Because str_replace() replaces left to right, it might replace a previously inserted value when doing multiple replacements.

    // Outputs F because A is replaced with B, then B is replaced with C, and so on...
    // Finally E is replaced with F, because of left to right replacements.
    $search  = array('A', 'B', 'C', 'D', 'E');
    $replace = array('B', 'C', 'D', 'E', 'F');
    $subject = 'A';
    echo str_replace($search, $replace, $subject);

Try this instead:

$journalName = preg_replace('/\s+/', '_', $journalName);

Explanation: you are most likely seeing whitespace, not just plain spaces (there is a difference).

Set your Textbox value in a string like:

string MySTring = textBox1.Text;

Then replace your string. For example, replace "Text" with "Hex":

MyString = MyString.Replace("Text", "Hex");

Or for your problem (replace "," with ;) :

MyString = MyString.Replace(@""",""", ",");

Note: If you have "" in your string you have to use @ in the back of "", like:

@"","";

What about Abseil StrReplaceAll? From the header file:

// This file defines `absl::StrReplaceAll()`, a general-purpose string
// replacement function designed for large, arbitrary text substitutions,
// especially on strings which you are receiving from some other system for
// further processing (e.g. processing regular expressions, escaping HTML
// entities, etc.). `StrReplaceAll` is designed to be efficient even when only
// one substitution is being performed, or when substitution is rare.
//
// If the string being modified is known at compile-time, and the substitutions
// vary, `absl::Substitute()` may be a better choice.
//
// Example:
//
// std::string html_escaped = absl::StrReplaceAll(user_input, {
//                                                {"&", "&"},
//                                                {"<", "&lt;"},
//                                                {">", "&gt;"},
//                                                {"\"", "&quot;"},
//                                                {"'", "&#39;"}});

I had a situation whereby I had to replace the HTML tags with two different replacement results.

$trades = "<li>Sprinkler and Fire      Protection Installer</li>
<li>Steamfitter </li>
<li>Terrazzo, Tile and Marble      Setter</li>";

$s1 =  str_replace('<li>', '"', $trades);

$s2 = str_replace('</li>', '",', $s1);

echo $s2;

result

"Sprinkler and Fire Protection Installer", "Steamfitter ", "Terrazzo, Tile and Marble Setter",

return sentence.replaceAll("\s",".");

that function replaces only one occurrence.. if you need to replace multiple occurrences you should try this function: http://phpjs.org/functions/str_replace:527

Not necessarily. see the Hans Kesting answer:

city_name = city_name.replace(/ /gi,'_');

Another possibility would be to use pidof it usually comes with most distributions. It will return you the PID of a given process by using it's name.

pidof process_name

This way you could store that information in a variable and execute kill -9 on it.

#!/bin/bash
pid=`pidof process_name`
kill -9 $pid

Here is a solution using INDIRECT, which if you drag the formula, it will pick up different cells from the target sheet accordingly. It uses R1C1 notation and is not limited to working only on columns A-Z.

=INDIRECT("'"&$A$5&"'!R"&ROW()&"C"&COLUMN(),FALSE)

This version picks up the value from the target cell corresponding to the cell where the formula is placed. For example, if you place the formula in 'Summary'!B5 then it will pick up the value from 'SERVER-ONE'!B5, not 'SERVER-ONE'!G7 as specified in the original question. But you could easily add in offsets to the row and column to achieve the desired mapping in any case.

I tried many of the solutions offered here, but eventually deleted the file and created it again, and Xcode was mollified :/

use std::map< std::string, std::map<std::string, std::string> >::const_iterator when map is const.

1. yes you can run it on iOS and Android (Win8 is not supported!
2. no deployment as a web-app does not work

You can use:

QString str = "10";
int n = str.toInt();

Output:

n = 10

QR codes have three parameters: Datatype, size (number of 'pixels') and error correction level. How much information can be stored there also depends on these parameters. For example the lower the error correction level, the more information that can be stored, but the harder the code is to recognize for readers.

The maximum size and the lowest error correction give the following values:
Numeric only Max. 7,089 characters
Alphanumeric Max. 4,296 characters
Binary/byte Max. 2,953 characters (8-bit bytes)

If you know the Start and End index, you can use

String substr=mysourcestring.substring(startIndex,endIndex);

If you want to get substring from specific index till end you can use :

String substr=mysourcestring.substring(startIndex);

If you want to get substring from specific character till end you can use :

String substr=mysourcestring.substring(mysourcestring.indexOf("characterValue"));

If you want to get substring from after a specific character, add that number to .indexOf(char):

String substr=mysourcestring.substring(mysourcestring.indexOf("characterValue") + 1);

You can convert your number to string and use list slicing like this:

int(str(number)[:2])

Output:

>>> number = 1520
>>> int(str(number)[:2])
15

I think inline scripts are hard to stop instead you can try with this:

<div id="test">
    <div>Click Me</div>
</div>

and script:

$(function () {
    $('#test').children().click(function(){
      alert('hello');
    });
    $('#test').children().off('click');
});

Declare it as a decimal which uses the int variable and divide this by 100

OK, so within minutes after posting the question, I found the answer myself here: https://github.com/npm/npm/issues/2119#issuecomment-5321857

The issue seems to be that npm is not that great with HTTPS over a proxy. Changing the registry URL from HTTPS to HTTP fixed it for me:

npm config set registry http://registry.npmjs.org/

I still have to provide the proxy config (through Authoxy in my case), but everything works fine now.

Seems to be a common issue, but not well documented. I hope this answer here will make it easier for people to find if they run into this issue.

If you have PHP installed on your server, you can create a php file, let's called it phpinfo.php and add this <?php echo phpinfo();?>, and open the file in your browser, this shows information about your system environment, to quickly find info about your Apache loaded modules, locate 'Loaded Modules' on the resulting page.

To have unique Categories:

var uniqueCategories =  repository.GetAllProducts()
                                  .Select(p=>p.Category)
                                  .Distinct();

try this:

powershell "C:\Dummy Directory 1\Foo.ps1 'C:\Dummy Directory 2\File.txt'"

This is what i've implemented:

$(window).resize(function(){ setTimeout(someFunction, 500); });

we can clear the setTimeout if we expect resize to happen less than 500ms

Good Luck...

Check whether your config string is okay:

Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9999

I just had this issue today, and in my case it was because there was an invisible character in the jpda config parameter.

To be precise, I had dos line endings in my setenv.sh file on tomcat, causing a carriage-return character right after 'dt_socket'

Use Mail::factory in the Mail PEAR package. Example.

The accepted answer is fine if you can use lookarounds. However, there is also another approach to solve this problem.

If we look at the widely proposed regex for this question:

.*[^a]$

We will find that it almost works. It does not accept an empty string, which might be a little inconvinient. However, this is a minor issue when dealing with just a one character. However, if we want to exclude whole string, e.g. "abc", then:

.*[^a][^b][^c]$

won't do. It won't accept ac, for example.

There is an easy solution for this problem though. We can simply say:

.{,2}$|.*[^a][^b][^c]$

or more generalized version:

.{,n-1}$|.*[^firstchar][^secondchar]$ where n is length of the string you want forbid (for abc it's 3), and firstchar, secondchar, ... are first, second ... nth characters of your string (for abc it would be a, then b, then c).

This comes from a simple observation that a string that is shorter than the text we won't forbid can not contain this text by definition. So we can either accept anything that is shorter("ab" isn't "abc"), or anything long enough for us to accept but without the ending.

Here's an example of find that will delete all files that are not .jpg:

find . -regex '.{,3}$|.*[^.][^j][^p][^g]$' -delete

The C# compiler will transform both

for(;;)
{
    // ...
}

and

while (true)
{
    // ...
}

into

{
    :label
    // ...
    goto label;
}

The CIL for both is the same. Most people find while(true) to be easier to read and understand. for(;;) is rather cryptic.

Source:

I messed a little more with .NET Reflector, and I compiled both loops with the "Optimize Code" on in Visual Studio.

Both loops compile into (with .NET Reflector):

Label_0000:
    goto Label_0000;

In order to uninstall miniconda, simply remove the miniconda folder,

rm -r ~/miniconda/

As for avoiding conflicts between different Python environments, you can use virtual environments. In particular, with Miniconda, the following workflow could be used,

$ wget https://repo.continuum.io/miniconda/Miniconda3-3.7.0-Linux-x86_64.sh -O ~/miniconda.sh
$ bash miniconda
$ conda env remove --yes -n new_env    # remove the environement new_env if it exists (optional)
$ conda create --yes -n new_env pip numpy pandas scipy matplotlib scikit-learn nltk ipython-notebook seaborn python=2
$ activate new_env
$ # pip install modules if needed, run python scripts, etc
  # everything will be installed in the new_env
  # located in ~/miniconda/envs/new_env
$ deactivate

Microsoft has listened to the cry for supporting installers (MSI) in Visual Studio and released the Visual Studio Installer Projects Extension. You can now create installers in Visual Studio 2013; download the extension here from the visualstudiogallery.

Ran to the same issue, Assuming your using anaconda3 and your using a venv with >= python=3.6:

python -m pip install keras
sudo python -m pip install --user tensorflow

It's a logic bomb, it keeps recreating itself and takes up all your CPU resources. It overloads your computer with too many processes and it forces it to shut down. If you make a batch file with this in it and start it you can end it using taskmgr. You have to do this pretty quickly or your computer will be too slow to do anything.

Another vi command that'll do: :%s/.$// This removes the last character of each line in the file. The drawback to this search and replace command is that it doesn't care what the last character is, so be careful not to call it twice.

If you want to refresh previous activity, this solution should work:

In previous activity where you want to refresh:

Specify the maxrecursion option at the end of the query:

...
from EmployeeTree
option (maxrecursion 0)

That allows you to specify how often the CTE can recurse before generating an error. Maxrecursion 0 allows infinite recursion.

i was trying the same, so i downloaded the .7zip version of XAMPP with php 5.6.33 from https://sourceforge.net/projects/xampp/files/XAMPP%20Windows/5.6.33/

then followed the steps below: 1. rename c:\xampp\php to c:\xampp\php7 2. raname C:\xampp\apache\conf\extra\httpd-xampp.conf to httpd-xampp7.OLD 3. copy php folder from XAMPP_5.6 7zip archive to c:\xampp\ 4. copy file httpd-xampp.conf from XAMPP_5.6 7zip archive to C:\xampp\apache\conf\extra\

open xampp control panel and start Apache and then visit ( i am using port 82 instead of default 80) http://localhost and then click PHPInfo to see if it is working as expected.

Opening localhost shows dashboard

Opening phpinfo shows version 5.6

It seems to me all existing answers on this page are wrong, including the one marked as correct. That stems from the fact that the question is ambiguously worded.

Summary:   If you want to execute the command "exactly once for each line of input," passing the entire line (without newline) to the command as a single argument, then this is the best UNIX-compatible way to do it:

... | tr '\n' '\0' | xargs -0 -n1 ...

If you are using GNU xargs and don't need to be compatible with all other UNIX's (FreeBSD, Mac OS X, etc.) then you can use the GNU-specific option -d:

... | xargs -d\\n -n1 ...

Now for the long explanation…

There are two issues to take into account when using xargs:

1. how does it split the input into "arguments"; and
2. how many arguments to pass the child command at a time.

To test xargs' behavior, we need an utility that shows how many times it's being executed and with how many arguments. I don't know if there is a standard utility to do that, but we can code it quite easily in bash:

#!/bin/bash
echo -n "-> "; for a in "$@"; do echo -n "\"$a\" "; done; echo

Assuming you save it as show in your current directory and make it executable, here is how it works:

$ ./show one two 'three and four'
-> "one" "two" "three and four" 

Now, if the original question is really about point 2. above (as I think it is, after reading it a few times over) and it is to be read like this (changes in bold):

How can I make xargs execute the command exactly once for each argument of input given? Its default behavior is to chunk the input into arguments and execute the command as few times as possible, passing multiple arguments to each instance.

then the answer is -n 1.

Let's compare xargs' default behavior, which splits the input around whitespace and calls the command as few times as possible:

$ echo one two 'three and four' | xargs ./show 
-> "one" "two" "three" "and" "four" 

and its behavior with -n 1:

$ echo one two 'three and four' | xargs -n 1 ./show 
-> "one" 
-> "two" 
-> "three" 
-> "and" 
-> "four" 

If, on the other hand, the original question was about point 1. input splitting and it was to be read like this (many people coming here seem to think that's the case, or are confusing the two issues):

How can I make xargs execute the command with exactly one argument for each line of input given? Its default behavior is to chunk the lines around whitespace.

then the answer is more subtle.

One would think that -L 1 could be of help, but it turns out it doesn't change argument parsing. It only executes the command once for each input line, with as many arguments as were there on that input line:

$ echo $'one\ntwo\nthree and four' | xargs -L 1 ./show 
-> "one" 
-> "two" 
-> "three" "and" "four" 

Not only that, but if a line ends with whitespace, it is appended to the next:

$ echo $'one \ntwo\nthree and four' | xargs -L 1 ./show 
-> "one" "two" 
-> "three" "and" "four" 

Clearly, -L is not about changing the way xargs splits the input into arguments.

The only argument that does so in a cross-platform fashion (excluding GNU extensions) is -0, which splits the input around NUL bytes.

Then, it's just a matter of translating newlines to NUL with the help of tr:

$ echo $'one \ntwo\nthree and four' | tr '\n' '\0' | xargs -0 ./show 
-> "one " "two" "three and four" 

Now the argument parsing looks all right, including the trailing whitespace.

Finally, if you combine this technique with -n 1, you get exactly one command execution per input line, whatever input you have, which may be yet another way to look at the original question (possibly the most intuitive, given the title):

$ echo $'one \ntwo\nthree and four' | tr '\n' '\0' | xargs -0 -n1 ./show 
-> "one " 
-> "two" 
-> "three and four" 

As mentioned above, if you are using GNU xargs you can replace the tr with the GNU-specific option -d:

$ echo $'one \ntwo\nthree and four' | xargs -d\\n -n1 ./show 
-> "one " 
-> "two" 
-> "three and four" 

I created an attached property based on Aviad's Answer which doesn't require creating a new class

public static class RadioButtonHelper
{
    [AttachedPropertyBrowsableForType(typeof(RadioButton))]
    public static object GetRadioValue(DependencyObject obj) => obj.GetValue(RadioValueProperty);
    public static void SetRadioValue(DependencyObject obj, object value) => obj.SetValue(RadioValueProperty, value);
    public static readonly DependencyProperty RadioValueProperty =
        DependencyProperty.RegisterAttached("RadioValue", typeof(object), typeof(RadioButtonHelper), new PropertyMetadata(new PropertyChangedCallback(OnRadioValueChanged)));

    private static void OnRadioValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        if (d is RadioButton rb)
        {
            rb.Checked -= OnChecked;
            rb.Checked += OnChecked;
        }
    }

    public static void OnChecked(object sender, RoutedEventArgs e)
    {
        if (sender is RadioButton rb)
        {
            rb.SetCurrentValue(RadioBindingProperty, rb.GetValue(RadioValueProperty));
        }
    }

    [AttachedPropertyBrowsableForType(typeof(RadioButton))]
    public static object GetRadioBinding(DependencyObject obj) => obj.GetValue(RadioBindingProperty);
    public static void SetRadioBinding(DependencyObject obj, object value) => obj.SetValue(RadioBindingProperty, value);

    public static readonly DependencyProperty RadioBindingProperty =
        DependencyProperty.RegisterAttached("RadioBinding", typeof(object), typeof(RadioButtonHelper), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, new PropertyChangedCallback(OnRadioBindingChanged)));

    private static void OnRadioBindingChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        if (d is RadioButton rb && rb.GetValue(RadioValueProperty).Equals(e.NewValue))
        {
            rb.SetCurrentValue(RadioButton.IsCheckedProperty, true);
        }
    }
}

usage :

<RadioButton GroupName="grp1" Content="Value 1"
    helpers:RadioButtonHelper.RadioValue="val1" helpers:RadioButtonHelper.RadioBinding="{Binding SelectedValue}"/>
<RadioButton GroupName="grp1" Content="Value 2"
    helpers:RadioButtonHelper.RadioValue="val2" helpers:RadioButtonHelper.RadioBinding="{Binding SelectedValue}"/>
<RadioButton GroupName="grp1" Content="Value 3"
    helpers:RadioButtonHelper.RadioValue="val3" helpers:RadioButtonHelper.RadioBinding="{Binding SelectedValue}"/>
<RadioButton GroupName="grp1" Content="Value 4"
    helpers:RadioButtonHelper.RadioValue="val4" helpers:RadioButtonHelper.RadioBinding="{Binding SelectedValue}"/>

You can achieve this with the usage of filter and next methods in Python.

filter method filters the given sequence and returns an iterator. next method accepts an iterator and returns the next element in the list.

So you can find the element by,

my_dict = [
    {"name": "Tom", "age": 10},
    {"name": "Mark", "age": 5},
    {"name": "Pam", "age": 7}
]

next(filter(lambda obj: obj.get('name') == 'Pam', my_dict), None)

and the output is,

{'name': 'Pam', 'age': 7}

Note: The above code will return None incase if the name we are searching is not found.

I think you are not configured properly,

if you are using XAMPP then you can easily send mail from localhost.

for example you can configure C:\xampp\php\php.ini and c:\xampp\sendmail\sendmail.ini for gmail to send mail.

in C:\xampp\php\php.ini find extension=php_openssl.dll and remove the semicolon from the beginning of that line to make SSL working for gmail for localhost.

in php.ini file find [mail function] and change

SMTP=smtp.gmail.com
smtp_port=587
sendmail_from = [email protected]
sendmail_path = "C:\xampp\sendmail\sendmail.exe -t"

(use the above send mail path only and it will work)

Now Open C:\xampp\sendmail\sendmail.ini. Replace all the existing code in sendmail.ini with following code

[sendmail]

smtp_server=smtp.gmail.com
smtp_port=587
error_logfile=error.log
debug_logfile=debug.log
[email protected]
auth_password=my-gmail-password
[email protected]

Now you have done!! create php file with mail function and send mail from localhost.

Update

First, make sure you PHP installation has SSL support (look for an "openssl" section in the output from phpinfo()).

You can set the following settings in your PHP.ini:

ini_set("SMTP","ssl://smtp.gmail.com");
ini_set("smtp_port","465");

I think these three links sum it up:

• http://tinodidriksen.com/2010/02/07/cpp-convert-int-to-string-speed/

• http://www.fastformat.org/performance.html

stringstream and lexical_cast solutions are about the same as lexical cast is using stringstream.

Some specializations of lexical cast use different approach see http://www.boost.org/doc/libs/release/boost/lexical_cast.hpp for details. Integers and floats are now specialized for integer to string conversion.

One can specialize lexical_cast for his/her own needs and make it fast. This would be the ultimate solution satisfying all parties, clean and simple.

Articles already mentioned show comparison between different methods of converting integers <-> strings. Following approaches make sense: old c-way, spirit.karma, fastformat, simple naive loop.

Lexical_cast is ok in some cases e.g. for int to string conversion.

Converting string to int using lexical cast is not a good idea as it is 10-40 times slower than atoi depending on the platform/compiler used.

Boost.Spirit.Karma seems to be the fastest library for converting integer to string.

ex.: generate(ptr_char, int_, integer_number);

and basic simple loop from the article mentioned above is a fastest way to convert string to int, obviously not the safest one, strtol() seems like a safer solution

int naive_char_2_int(const char *p) {
    int x = 0;
    bool neg = false;
    if (*p == '-') {
        neg = true;
        ++p;
    }
    while (*p >= '0' && *p <= '9') {
        x = (x*10) + (*p - '0');
        ++p;
    }
    if (neg) {
        x = -x;
    }
    return x;
}

Well there are two methods to access this data easier, but the interface doesn't offer the possibility to get the whole URL with one call. You have to build it manually:

public static String makeUrl(HttpServletRequest request)
{
    return request.getRequestURL().toString() + "?" + request.getQueryString();
}

I don't know about a way to do this with any Spring MVC facilities.

If you want to access the current Request without passing it everywhere you will have to add a listener in the web.xml:

<listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
</listener>

And then use this to get the request bound to the current Thread:

((ServletRequestAttributes) RequestContextHolder.currentRequestAttributes()).getRequest()

Try using MySQLdb. MySQLdb only supports Python 2.

There is a how to page here: http://www.kitebird.com/articles/pydbapi.html

From the page:

# server_version.py - retrieve and display database server version

import MySQLdb

conn = MySQLdb.connect (host = "localhost",
                        user = "testuser",
                        passwd = "testpass",
                        db = "test")
cursor = conn.cursor ()
cursor.execute ("SELECT VERSION()")
row = cursor.fetchone ()
print "server version:", row[0]
cursor.close ()
conn.close ()

Implementations

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

On virtual hosting check your disk quota.

if quota exceed, move_uploaded_file return error.

PS : I've been looking for this for a long time :)

please consider .editorconfig overwrites everything, use:

[*]
quote_type = single

If you actually want a C-style array

import array
a = array.array('i', x * [0])
a[3] = 5
try:
   [5] = 'a'
except TypeError:
   print('integers only allowed')

Note that there's no concept of un-initialized variable in python. A variable is a name that is bound to a value, so that value must have something. In the example above the array is initialized with zeros.

However, this is uncommon in python, unless you actually need it for low-level stuff. In most cases, you are better-off using an empty list or empty numpy array, as other answers suggest.

When you run Python interactively the local __name__ variable is assigned a value of __main__. Likewise, when you execute a Python module from the command line, rather than importing it into another module, its __name__ attribute is assigned a value of __main__, rather than the actual name of the module. In this way, modules can look at their own __name__ value to determine for themselves how they are being used, whether as support for another program or as the main application executed from the command line. Thus, the following idiom is quite common in Python modules:

if __name__ == '__main__':
    # Do something appropriate here, like calling a
    # main() function defined elsewhere in this module.
    main()
else:
    # Do nothing. This module has been imported by another
    # module that wants to make use of the functions,
    # classes and other useful bits it has defined.

CARL LANGE also showed how to get hidden, autoplaying audio in html5 on a iOS device. Works for me.

In HTML,

<div id="hideme">
    <audio id="audioTag" controls>
        <source src="/path/to/audio.mp3">
    </audio>
</div>

with JS

<script type="text/javascript">
window.onload = function() {
    var audioEl = document.getElementById("audioTag");
    audioEl.load();
    audioEl.play();
};
</script>

In CSS,

#hideme {display: none;}

My solution:

Object.prototype.__index = function(index)
{
    var i = -1;
    for (var key in this)
    {
        if (this.hasOwnProperty(key) && typeof(this[key])!=='function')
            ++i;
        if (i >= index)
            return this[key];
    }
    return null;
}
aObj = {'jack':3, 'peter':4, '5':'col', 'kk':function(){alert('hell');}, 'till':'ding'};
alert(aObj.__index(4));

Given a Window object myWindow, myWindow.Show() will open it modelessly and myWindow.ShowDialog() will open it modally. However, even the latter doesn't block, from what I remember.

Theres the ByteArrayInputStream.

It does exactly this.

I'm always running tests against an in-memory DB (HSQLDB or Derby) for these reasons:

• It makes you think which data to keep in your test DB and why. Just hauling your production DB into a test system translates to "I have no idea what I'm doing or why and if something breaks, it wasn't me!!" ;)
• It makes sure the database can be recreated with little effort in a new place (for example when we need to replicate a bug from production)
• It helps enormously with the quality of the DDL files.

The in-memory DB is loaded with fresh data once the tests start and after most tests, I invoke ROLLBACK to keep it stable. ALWAYS keep the data in the test DB stable! If the data changes all the time, you can't test.

The data is loaded from SQL, a template DB or a dump/backup. I prefer dumps if they are in a readable format because I can put them in VCS. If that doesn't work, I use a CSV file or XML. If I have to load enormous amounts of data ... I don't. You never have to load enormous amounts of data :) Not for unit tests. Performance tests are another issue and different rules apply.

I didn't understand why my this didn't work but I found out that this setting is now also under the programming language itself at:

'Editor' | 'Code Style' | < your language > | 'Wrapping and Braces' | 'Right margin (columns)'

I figured that one solution would be to run a batch operation on the Eclipse JAR's which contain the icons and double their size. After a bit of tinkering, it worked. Results are pretty good - there's still a few "stubborn" icons which are tiny but most look good.

I put together the code into a small project: https://github.com/davidglevy/eclipse-icon-enlarger

The project works by:

1. Iterating over every file in the eclipse base directory (specified in argument line)
2. If a file is a directory, create a new directory under the present one in the output folder (specified in the argument line)
3. If a file is a PNG or GIF, double
4. If a file is another type copy
5. If a file is a JAR or ZIP, create a target file and process the contents using a similar process: a. Images are doubled b. Other files are copied across into the ZipOutputStream as is.

The only problem I've found with this solution is that it really only works once - if you need to download plugins then do so in the original location and re-apply the icon increase batch process.

On the Dell XPS it takes about 5 minutes to run.

Happy for suggestions/improvements but this is really just an adhoc solution while we wait for the Eclipse team to get a fix out.

Welcome to 2019!

It appears a proposal to extend class syntax to allow for # prefixed variable to be private was accepted. Chrome 74 ships with this support.

_ prefixed variable names are considered private by convention but are still public.

This syntax tries to be both terse and intuitive, although it's rather different from other programming languages.

Why was the sigil # chosen, among all the Unicode code points?

• @ was the initial favorite, but it was taken by decorators. TC39 considered swapping decorators and private state sigils, but the committee decided to defer to the existing usage of transpiler users.
• _ would cause compatibility issues with existing JavaScript code, which has allowed _ at the start of an identifier or (public) property name for a long time.

This proposal reached Stage 3 in July 2017. Since that time, there has been extensive thought and lengthy discussion about various alternatives. In the end, this thought process and continued community engagement led to renewed consensus on the proposal in this repository. Based on that consensus, implementations are moving forward on this proposal.

See https://caniuse.com/#feat=mdn-javascript_classes_private_class_fields

You can also pass a RegExp object to the replace method like

var regexUnderscore = new RegExp("_", "g"); //indicates global match
var regexHash = new RegExp("#", "g");

string.replace(regexHash, "").replace(regexUnderscore, " ");

Javascript RegExp

Just make a rule for each case:

<div id="homePage" ng-class="{ 'center': page.isSelected(1) , 'left': !page.isSelected(1)  }">

Or use the ternary operator:

<div id="homePage" ng-class="page.isSelected(1) ? 'center' : 'left'">

You can add a little syntax sugar to the above solution with the following:

class Time
  def to_ms
    (self.to_f * 1000.0).to_i
  end
end

start_time = Time.now
sleep(3)
end_time = Time.now
elapsed_time = end_time.to_ms - start_time.to_ms  # => 3004

What Anthony says is absolutely correct, but I'd like to add that your experience will likely show a lot better performance and efficiency (due not to fpm-vs-fcgi but more to the implementation of your httpd).

For example, I had a quad-core machine running lighttpd + fcgi humming along nicely. I upgraded to a 16-core machine to cope with growth, and two things exploded: RAM usage, and segfaults. I found myself restarting lighttpd every 30 minutes to keep the website up.

I switched to php-fpm and nginx, and RAM usage dropped from >20GB to 2GB. Segfaults disappeared as well. After doing some research, I learned that lighttpd and fcgi don't get along well on multi-core machines under load, and also have memory leak issues in certain instances.

Is this due to php-fpm being better than fcgi? Not entirely, but how you hook into php-fpm seems to be a whole heckuva lot more efficient than how you serve via fcgi.

Additional tip for ASP NET CORE:

Interface:

public interface IViewRenderer
{
  Task<string> RenderAsync<TModel>(Controller controller, string name, TModel model);
}

Implementation:

public class ViewRenderer : IViewRenderer
{
  private readonly IRazorViewEngine viewEngine;

  public ViewRenderer(IRazorViewEngine viewEngine) => this.viewEngine = viewEngine;

  public async Task<string> RenderAsync<TModel>(Controller controller, string name, TModel model)
  {
    ViewEngineResult viewEngineResult = this.viewEngine.FindView(controller.ControllerContext, name, false);

    if (!viewEngineResult.Success)
    {
      throw new InvalidOperationException(string.Format("Could not find view: {0}", name));
    }

    IView view = viewEngineResult.View;
    controller.ViewData.Model = model;

    await using var writer = new StringWriter();
    var viewContext = new ViewContext(
       controller.ControllerContext,
       view,
       controller.ViewData,
       controller.TempData,
       writer,
       new HtmlHelperOptions());

       await view.RenderAsync(viewContext);

       return writer.ToString();
  }
}

Registration in Startup.cs

...
 services.AddSingleton<IViewRenderer, ViewRenderer>();
...

And usage in controller:

public MyController: Controller
{
  private readonly IViewRenderer renderer;
  public MyController(IViewRendere renderer) => this.renderer = renderer;
  public async Task<IActionResult> MyViewTest
  {
    var view = await this.renderer.RenderAsync(this, "MyView", model);
    return new OkObjectResult(view);
  }
}

If your looking for something a little more native, you can use getGnuWin32 to install all of the unix command line tools that have been ported. That plus winBash gives you most of a working unix environment. Add console2 for a better terminal emulator and you almost can't tell your on windows!

Cygwin is a better toolkit overall, but I have found myself running into suprise problems because of the divide between it and windows. None of these solutions are as good as a native linux system though.

You may want to look into using virtualbox to create a linux VM with your distro of choice. Set it up to share a folder with the host os, and you can use a true linux development environment, and share with windows. Just watch out for those EOL markers, they get ya every time.

For greater than 24 hours you can include days with the following query. The returned format is days:hh24:mi:ss

Query:
select trunc(trunc(sysdate) + numtodsinterval(9999999, 'second')) - trunc(sysdate) || ':' || to_char(trunc(sysdate) + numtodsinterval(9999999, 'second'), 'hh24:mi:ss') from dual;

Output:
115:17:46:39

You can try this:

 string sql = "UPDATE Customer SET City = @City WHERE CustomerId = @CustomerId";             
 conn.Execute(sql, customerEntity);

Notionally a += b "adds" b to a storing the result in a. This simplistic description would describe the += operator in many languages.

However the simplistic description raises a couple of questions.

1. What exactly do we mean by "adding"?
2. What exactly do we mean by "storing the result in a"? python variables don't store values directly they store references to objects.

In python the answers to both of these questions depend on the data type of a.

So what exactly does "adding" mean?

• For numbers it means numeric addition.
• For lists, tuples, strings etc it means concatenation.

Note that for lists += is more flexible than +, the + operator on a list requires another list, but the += operator will accept any iterable.

So what does "storing the value in a" mean?

If the object is mutable then it is encouraged (but not required) to perform the modification in-place. So a points to the same object it did before but that object now has different content.

If the object is immutable then it obviously can't perform the modification in-place. Some mutable objects may also not have an implementation of an in-place "add" operation . In this case the variable "a" will be updated to point to a new object containing the result of an addition operation.

Technically this is implemented by looking for __IADD__ first, if that is not implemented then __ADD__ is tried and finally __RADD__.

Care is required when using += in python on variables where we are not certain of the exact type and in particular where we are not certain if the type is mutable or not. For example consider the following code.

def dostuff(a):
    b = a
    a += (3,4)
    print(repr(a)+' '+repr(b))

dostuff((1,2))
dostuff([1,2])

When we invoke dostuff with a tuple then the tuple is copied as part of the += operation and so b is unaffected. However when we invoke it with a list the list is modified in place, so both a and b are affected.

In python 3, similar behaviour is observed with the "bytes" and "bytearray" types.

Finally note that reassignment happens even if the object is not replaced. This doesn't matter much if the left hand side is simply a variable but it can cause confusing behaviour when you have an immutable collection referring to mutable collections for example:

a = ([1,2],[3,4])
a[0] += [5]

In this case [5] will successfully be added to the list referred to by a[0] but then afterwards an exception will be raised when the code tries and fails to reassign a[0].

The nabvar will collapse on small devices. The point of collapsing is defined by @grid-float-breakpoint in variables. By default this will by before 768px. For screens below the 768 pixels screen width, the navbar will look like:

It's possible to change the @grid-float-breakpoint in variables.less and recompile Bootstrap. When doing this you also will have to change @screen-xs-max in navbar.less. You will have to set this value to your new @grid-float-breakpoint -1. See also: https://github.com/twbs/bootstrap/pull/10465. This is needed to change navbar forms and dropdowns at the @grid-float-breakpoint to their mobile version too.

Easiest way is to customize bootstrap

find variable:

 @grid-float-breakpoint

which is set to @screen-sm, you can change it according to your needs. Hope it helps!

For SAAS Users

add your custom variables like $grid-float-breakpoint: 0px; before the @import "bootstrap.scss";

If you're developing an application from scratch, you can make some educated choices about when to call free. Your example program is fine: it allocates memory, maybe you have it work for a few seconds, and then closes, freeing all the resources it claimed.

If you're writing anything else, though -- a server/long-running application, or a library to be used by someone else, you should expect to call free on everything you malloc.

Ignoring the pragmatic side for a second, it's much safer to follow the stricter approach, and force yourself to free everything you malloc. If you're not in the habit of watching for memory leaks whenever you code, you could easily spring a few leaks. So in other words, yes -- you can get away without it; please be careful, though.

Keep in mind, the jQuery UI's datepicker is not initialized with datetimepicker(), there appears to be a plugin/addon here: http://trentrichardson.com/examples/timepicker/.

However, with just jquery-ui it's actually initialized as $("#example").datepicker(). See jQuery's demo site here: http://jqueryui.com/demos/datepicker/

   $(document).ready(function(){
        $("#example1").datepicker();
    });

To use the datetimepicker at the link referenced above, you will want to be certain that your scripts path is correct for the plugin.

WOW! After reading all the above I find myself overwhelmed and confused. I took what I thought I learned in this post and tried something completely different. To select the text in a TexTbox when it gets focus I use this:

private void TextField_GotFocus(object sender, RoutedEventArgs e)
{
    TextBox tb = (sender as Textbox);
    if(tb != null)
    {
        e.Handled = true;
        tb.Focus();
        tb.SelectAll();
    }
}

Set the GotFocus property of the TexTbox to this method.

Running the application and clicking once in the TexTbox highlights everything already in the TexTbox.

If indeed, the objective is to select the text when the user clicks in the TexTbox, this seems simple and involves a whole lot less code. Just saying...

There's a simpler and more efficient way, using the native shell prefix/suffix removal feature:

temp="${opt%\"}"
temp="${temp#\"}"
echo "$temp"

${opt%\"} will remove the suffix " (escaped with a backslash to prevent shell interpretation).

${temp#\"} will remove the prefix " (escaped with a backslash to prevent shell interpretation).

Another advantage is that it will remove surrounding quotes only if there are surrounding quotes.

BTW, your solution always removes the first and last character, whatever they may be (of course, I'm sure you know your data, but it's always better to be sure of what you're removing).

Using sed:

echo "$opt" | sed -e 's/^"//' -e 's/"$//'

(Improved version, as indicated by jfgagne, getting rid of echo)

sed -e 's/^"//' -e 's/"$//' <<<"$opt"

So it replaces a leading " with nothing, and a trailing " with nothing too. In the same invocation (there isn't any need to pipe and start another sed. Using -e you can have multiple text processing).

Nothing new but caching your jQuery collections will have a small perf boost

$(function() {

    var $typeSelector = $('#type');
    var $toggleArea = $('#row_dim');

    $typeSelector.change(function(){
        if ($typeSelector.val() === 'parcel') {
            $toggleArea.show(); 
        }
        else {
            $toggleArea.hide(); 
        }
    });
});

And in vanilla JS for super speed:

(function() {

    var typeSelector = document.getElementById('type');
    var toggleArea = document.getElementById('row_dim');

    typeSelector.onchange = function() {
        toggleArea.style.display = typeSelector.value === 'parcel'
            ? 'block'
            : 'none';
    };

});

This will work for ENUM type as default value

ALTER TABLE engagete_st.holidays add column `STATUS` ENUM('A', 'D') default 'A' AFTER `H_TYPE`;

One approach would be to iterate over the array, calling the description message on each item:

NSMutableString * result = [[NSMutableString alloc] init];
for (NSObject * obj in array)
{
    [result appendString:[obj description]];
}
NSLog(@"The concatenated string is %@", result);

Another approach would be to do something based on each item's class:

NSMutableString * result = [[NSMutableString alloc] init];
for (NSObject * obj in array)
{
    if ([obj isKindOfClass:[NSNumber class]])
    {
        // append something
    }
    else
    {
        [result appendString:[obj description]];
    }
}
NSLog(@"The concatenated string is %@", result);

If you want commas and other extraneous information, you can just do:

NSString * result = [array description];

You can find and kill the running processes: ps aux | grep puma Then you can kill it with kill PID

The operators && and || are short-circuiting, meaning they will not evaluate their right-hand expression if the value of the left-hand expression is enough to determine the result.

The following function parseHTML will return either :

• a Document when your file starts with a doctype.

• a DocumentFragment when your file doesn't start with a doctype.

The code :

function parseHTML(markup) {
    if (markup.toLowerCase().trim().indexOf('<!doctype') === 0) {
        var doc = document.implementation.createHTMLDocument("");
        doc.documentElement.innerHTML = markup;
        return doc;
    } else if ('content' in document.createElement('template')) {
       // Template tag exists!
       var el = document.createElement('template');
       el.innerHTML = markup;
       return el.content;
    } else {
       // Template tag doesn't exist!
       var docfrag = document.createDocumentFragment();
       var el = document.createElement('body');
       el.innerHTML = markup;
       for (i = 0; 0 < el.childNodes.length;) {
           docfrag.appendChild(el.childNodes[i]);
       }
       return docfrag;
    }
}

How to use :

var links = parseHTML('<!doctype html><html><head></head><body><a>Link 1</a><a>Link 2</a></body></html>').getElementsByTagName('a');

intern ? symbol Returns the Symbol corresponding to str, creating the symbol if it did not previously exist

"edition".intern # :edition

http://ruby-doc.org/core-2.1.0/String.html#method-i-intern

With JavaScript:

if (/Trident/g.test(navigator.userAgent)) { // detect trident engine so IE
        document.getElementsByTagName('html')[0].className= 'no-js ie'; }

Work for all IE.

IE08 => 'Trident/4.0'

IE09 => 'Trident/5.0'

IE10 => 'Trident/6.0'

IE11 => 'Trident/7.0'

So change /Trident/g by /Trident/x.0/g where x = 4, 5, 6 or 7 (or maybe 8 for the future).

Write your function this way:

onToggleLoop = (event) => {
    this.setState({loopActive: !this.state.loopActive})
    this.props.onToggleLoop()
}

Fat Arrow Functions

the binding for the keyword this is the same outside and inside the fat arrow function. This is different than functions declared with function, which can bind this to another object upon invocation. Maintaining the this binding is very convenient for operations like mapping: this.items.map(x => this.doSomethingWith(x)).

Strictly speaking, the difference between Database and Schema is inexisting in MySql.

However, this is not the case in other database engines such as SQL Server. In SQL server:,

Every table belongs to a grouping of objects in the database called database schema. It's a container or namespace (Querying Microsoft SQL Server 2012)

By default, all the tables in SQL Server belong to a default schema called dbo. When you query a table that hasn't been allocated to any particular schema, you can do something like:

SELECT *
FROM your_table

which is equivalent to:

SELECT *
FROM dbo.your_table

Now, SQL server allows the creation of different schema, which gives you the possibility of grouping tables that share a similar purpose. That helps to organize the database.

For example, you can create an schema called sales, with tables such as invoices, creditorders (and any other related with sales), and another schema called lookup, with tables such as countries, currencies, subscriptiontypes (and any other table used as look up table).

The tables that are allocated to a specific domain are displayed in SQL Server Studio Manager with the schema name prepended to the table name (exactly the same as the tables that belong to the default dbo schema).

There are special schemas in SQL Server. To quote the same book:

There are several built-in database schemas, and they can't be dropped or altered:

1) dbo, the default schema.

2) guest contains objects available to a guest user ("guest user" is a special role in SQL Server lingo, with some default and highly restricted permissions). Rarely used.

3) INFORMATION_SCHEMA, used by the Information Schema Views

4) sys, reserved for SQL Server internal use exclusively

Schemas are not only for grouping. It is actually possible to give different permissions for each schema to different users, as described MSDN.

Doing this way, the schema lookup mentioned above could be made available to any standard user in the database (e.g. SELECT permissions only), whereas a table called supplierbankaccountdetails may be allocated in a different schema called financial, and to give only access to the users in the group accounts (just an example, you get the idea).

Finally, and quoting the same book again:

It isn't the same Database Schema and Table Schema. The former is the namespace of a table, whereas the latter refers to the table definition

You can explicitly specify the return type of a lambda by using -> Type after the arguments list:

[]() -> Type { }

However, if a lambda has one statement and that statement is a return statement (and it returns an expression), the compiler can deduce the return type from the type of that one returned expression. You have multiple statements in your lambda, so it doesn't deduce the type.

Just had similar question and decided to try out some of the suggestions in this thread.

I've benchmarked best and worst case scenarios of 3 types of lookup:

• using a map
• using a list
• using a switch statement

here's the function code:

func belongsToMap(lookup string) bool {
list := map[string]bool{
    "900898296857": true,
    "900898302052": true,
    "900898296492": true,
    "900898296850": true,
    "900898296703": true,
    "900898296633": true,
    "900898296613": true,
    "900898296615": true,
    "900898296620": true,
    "900898296636": true,
}
if _, ok := list[lookup]; ok {
    return true
} else {
    return false
}
}


func belongsToList(lookup string) bool {
list := []string{
    "900898296857",
    "900898302052",
    "900898296492",
    "900898296850",
    "900898296703",
    "900898296633",
    "900898296613",
    "900898296615",
    "900898296620",
    "900898296636",
}
for _, val := range list {
    if val == lookup {
        return true
    }
}
return false
}

func belongsToSwitch(lookup string) bool {
switch lookup {
case
    "900898296857",
    "900898302052",
    "900898296492",
    "900898296850",
    "900898296703",
    "900898296633",
    "900898296613",
    "900898296615",
    "900898296620",
    "900898296636":
    return true
}
return false
}

best case scenarios pick the first item in lists, worst case ones use nonexistant value.

here are the results:

BenchmarkBelongsToMapWorstCase-4 2000000 787 ns/op BenchmarkBelongsToSwitchWorstCase-4 2000000000 0.35 ns/op BenchmarkBelongsToListWorstCase-4 100000000 14.7 ns/op BenchmarkBelongsToMapBestCase-4 2000000 683 ns/op BenchmarkBelongsToSwitchBestCase-4 100000000 10.6 ns/op BenchmarkBelongsToListBestCase-4 100000000 10.4 ns/op

Switch wins all the way, worst case is surpassingly quicker than best case. Maps are the worst and list is closer to switch.

So the moral is: If you have a static, reasonably small list, switch statement is the way to go.

json.dumps() is used to decode JSON data

import json

# initialize different data
str_data = 'normal string'
int_data = 1
float_data = 1.50
list_data = [str_data, int_data, float_data]
nested_list = [int_data, float_data, list_data]
dictionary = {
    'int': int_data,
    'str': str_data,
    'float': float_data,
    'list': list_data,
    'nested list': nested_list
}

# convert them to JSON data and then print it
print('String :', json.dumps(str_data))
print('Integer :', json.dumps(int_data))
print('Float :', json.dumps(float_data))
print('List :', json.dumps(list_data))
print('Nested List :', json.dumps(nested_list, indent=4))
print('Dictionary :', json.dumps(dictionary, indent=4))  # the json data will be indented

output:

String : "normal string"
Integer : 1
Float : 1.5
List : ["normal string", 1, 1.5]
Nested List : [

You can avoid using the --onto parameter by making a temp branch on the commit you like and then use rebase in its simple form:

git branch temp master^
git checkout topic
git rebase temp
git branch -d temp

When using JavaScript to access an HTML element, there is a good chance that the element is not on the page and therefore not in the dom as far as JavaScript is concerned, when the code to access that element runs.

This problem can occur even though you can visually see the HTML element in the browser window or have the code set to be called in the onload method.

I ran into this problem after writing code to repopulate specific div elements on a page after retrieving the cookies.

What is apparently happening is that even though the HTML has loaded and is outputted by the browser, the JavaScript code is running before the page has completed loading.

The solution to this problem which just may be a JavaScript bug, is to place the code you want to run within a timer that delays the code run by 400 milliseconds or so. You will need to test it to determine how quick you can run the code.

I also made a point to test for the element before attempting to assign values to it.

window.setTimeout(function() { if( document.getElementById("book") ) { // Code goes here }, 400 /* but after 400 ms */);

This may or may not help you solve your problem, but keep this in mind and understand that browsers do not always function as expected.

I'd build a list of keys that need removing, then remove them. It's simple, efficient and avoids any problem about simultaneously iterating over and mutating the dict.

keys_to_remove = [key for key, value in some_dict.iteritems()
                  if value == value_to_remove]
for key in keys_to_remove:
    del some_dict[key]

JSONObject typically uses HashMap internally to store the data. So, you can use it as Map in your code.

Example,

JSONObject obj = JSONObject.fromObject(strRepresentation);
Iterator i = obj.entrySet().iterator();
while (i.hasNext()) {
   Map.Entry e = (Map.Entry)i.next();
   System.out.println("Key: " + e.getKey());
   System.out.println("Value: " + e.getValue());
}

getResource by example:

package szb.testGetResource;
public class TestGetResource {
    private void testIt() {
        System.out.println("test1: "+TestGetResource.class.getResource("test.css"));
        System.out.println("test2: "+getClass().getResource("test.css"));
    }
    public static void main(String[] args) {
        new TestGetResource().testIt();
    }
}

output:

test1: file:/home/szb/projects/test/bin/szb/testGetResource/test.css
test2: file:/home/szb/projects/test/bin/szb/testGetResource/test.css

If you want to make sure that newly created projects or imported projects in Eclipse use another default java version than Java 1.5, you can change the configuration in the maven-compiler-plugin.

• Go to the folder .m2/repository/org/apache/maven/plugins/maven-compiler-plugin/3.1
• Open maven-compiler-plugin-3.1.jar with a zip program.
• Go to META-INF/maven and open the plugin.xml

• In the following lines:
  <source implementation="java.lang.String" default-value="1.5">${maven.compiler.source}</source>
  <target implementation="java.lang.String" default-value="1.5">${maven.compiler.target}</target>

• change the default-value to 1.6 or 1.8 or whatever you like.

• Save the file and make sure it is written back to the zip file.

From now on all new Maven projects use the java version you specified.

Information is from the following blog post: https://sandocean.wordpress.com/2019/03/22/directly-generating-maven-projects-in-eclipse-with-java-version-newer-than-1-5/

C# compiler is a two phase compiler. In the first phase it just checks namespaces, class hierarchies, Method signatures etc. Method bodies are compiled only during the second phase.

Anonymous types are not determined until the method body is compiled.

So the compiler has no way of determining the return type of the method during the first phase.

That is the reason why anonymous types can not be used as return type.

As others have suggested if you are using .net 4.0 or grater, you can use Dynamic.

If I were you I would probably create a type and return that type from the method. That way it is easy for the future programmers who maintains your code and more readable.

I'm pretty mixed up on this. I am also running Excel 2010. I tried saving two sheets as a single PDF using:

    ThisWorkbook.Sheets(Array(1,2)).Select
    **Selection**.ExportAsFixedFormat xlTypePDF, FileName & ".pdf", , , False

but I got nothing but blank pages. It saved both sheets, but nothing on them. It wasn't until I used:

    ThisWorkbook.Sheets(Array(1,2)).Select
    **ActiveSheet**.ExportAsFixedFormat xlTypePDF, FileName & ".pdf", , , False

that I got a single PDF file with both sheets.

I tried manually saving these two pages using Selection in the Options dialog to save the two sheets I had selected, but got blank pages. When I tried the Active Sheet(s) option, I got what I wanted. When I recorded this as a macro, Excel used ActiveSheet when it successfully published the PDF. What gives?

Another way to think of it is to calculate the unit vector for a given direction and then apply a 90 degree counterclockwise rotation to get the normal vector.

The matrix representation of the general 2D transformation looks like this:

x' = x cos(t) - y sin(t)
y' = x sin(t) + y cos(t)

where (x,y) are the components of the original vector and (x', y') are the transformed components.

If t = 90 degrees, then cos(90) = 0 and sin(90) = 1. Substituting and multiplying it out gives:

x' = -y
y' = +x

Same result as given earlier, but with a little more explanation as to where it comes from.

The following snippet will attempt to execute the "doStuff" function 2 seconds after the mouseDown event occurs in document.body. If the user lifts up the button, the mouseUp event will occur and cancel the delayed execution.

I'd advise using some method for cross-browser event attachment - setting the mousedown and mouseup properties explicitly was done to simplify the example.

function doStuff() {
  // does something when mouse is down in body for longer than 2 seconds
}

var mousedownTimeout;

document.body.onmousedown = function() { 
  mousedownTimeout = window.setTimeout(doStuff, 2000);
}

document.body.onmouseup = function() {
  window.clearTimeout(mousedownTimeout);
}

You had MarginTop instead of marginTop

It is also very buggy if you leave mid animation, here is update:

http://jsfiddle.net/kX7b6/3/

Note I changed it to mouseenter and mouseleave because I don't think the intention was to cancel the animation when you hover over the red or green area.

Just go to the (app level) build.gradle file, give an empty space somewhere and click on sync, once gradle shows sync complete then the Error will be gone

Apache Commons I/O provides FileUtils#readLines(), which should be fine for all but huge files: http://commons.apache.org/io/api-release/index.html. The 2.1 distribution includes FileUtils.lineIterator(), which would be suitable for large files. Google's Guava libraries include similar utilities.

You could try:

print ''.join(ch for ch in some_string if ch.isalnum())

I found these two links very helpful while I was trying to learn socket.io:

You can use Random.Next(int maxValue):

Return: A 32-bit signed integer greater than or equal to zero, and less than maxValue; that is, the range of return values ordinarily includes zero but not maxValue. However, if maxValue equals zero, maxValue is returned.

var r = new Random();
// print random integer >= 0 and  < 100
Console.WriteLine(r.Next(100));

For this case however you could use Random.Next(int minValue, int maxValue), like this:

// print random integer >= 1 and < 101
Console.WriteLine(r.Next(1, 101);)
// or perhaps (if you have this specific case)
Console.WriteLine(r.Next(100) + 1);

I looked at some of the solutions and they're great but I think I found a surprisingly easy way.

First, we need to get the ratio from the background image. We simply divide one dimension through another. Then we get something like for example 66.4%

When we have image ratio we can simply calculate the height of the div by multiplying the ratio by viewport width:

height: calc(0.664 * 100vw);

To me, it works, sets div height properly and changes it when the window is resized.

same happen to me i just resolved by deleting "dist" file and re run the app.

String is a reference type and always nullable, you don't need to do anything special. Specifying that a type is nullable is necessary only for value types.

In Mathematics, where these conventions stem from, there is no assertion that modulo arithmetic should yield a positive result.

Eg.

1 mod 5 = 1, but it can also equal -4. That is, 1/5 yields a remainder 1 from 0 or -4 from 5. (Both factors of 5)

Similarly, -1 mod 5 = -1, but it can also equal 4. That is, -1/5 yields a remainder -1 from 0 or 4 from -5. (Both factors of 5)

For further reading look into equivalence classes in Mathematics.

opt is new for ruby 1.9. The various options are documented in IO.new : www.ruby-doc.org/core/IO.html

This depends on implementation, but the general rule is that the domain is checked against all SANs and the common name. If the domain is found there, then the certificate is ok for connection.

RFC 5280, section 4.1.2.6 says "The subject name MAY be carried in the subject field and/or the subjectAltName extension". This means that the domain name must be checked against both SubjectAltName extension and Subject property (namely it's common name parameter) of the certificate. These two places complement each other, and not duplicate it. And SubjectAltName is a proper place to put additional names, such as www.domain.com or www2.domain.com

Update: as per RFC 6125, published in 2011, the validator must check SAN first, and if SAN exists, then CN should not be checked. Note that RFC 6125 is relatively recent and there still exist certificates and CAs that issue certificates, which include the "main" domain name in CN and alternative domain names in SAN. I.e. by excluding CN from validation if SAN is present, you can deny some otherwise valid certificate.

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

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

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

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

https://github.com/kcsaff/getkey

Can allow for a more elegant solution.

Code example:

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

You can try this code:

#include <algorithm>
#include <vector>

// You can use class, struct or primitive data type for Item
struct Item {
    //Some fields
};
typedef std::vector<Item> ItemVector;
typedef ItemVector::iterator ItemIterator;
//...
ItemVector vtItem;
//... (init data for vtItem)
Item itemToFind;
//...

ItemIterator itemItr;
itemItr = std::find(vtItem.begin(), vtItem.end(), itemToFind);
if (itemItr != vtItem.end()) {
    // Item found
    // doThis()
}
else {
    // Item not found
    // doThat()
}

You can write this in a more compact way:

var now = new Date();
now.setTime(now.getTime() + 1 * 3600 * 1000);
document.cookie = "name=value; expires=" + now.toUTCString() + "; path=/";

And for someone like me, who wasted an hour trying to figure out why the cookie with expiration is not set up (but without expiration can be set up) in Chrome, here is in answer:

For some strange reason Chrome team decided to ignore cookies from local pages. So if you do this on localhost, you will not be able to see your cookie in Chrome. So either upload it on the server or use another browser.

Some notes to complement the ALTER DATABASE process:

1) You can obtain a full list of databases with logical names and full paths of MDF and LDF files:

   USE master SELECT name, physical_name FROM sys.master_files

2) You can move manually the files with CMD move command:

Move "Source" "Destination"

Example:

md "D:\MSSQLData"
Move "C:\test\SYSADMIT-DB.mdf" "D:\MSSQLData\SYSADMIT-DB_Data.mdf"
Move "C:\test\SYSADMIT-DB_log.ldf" "D:\MSSQLData\SYSADMIT-DB_log.ldf"

3) You should change the default database path for new databases creation. The default path is obtained from the Windows registry.

You can also change with T-SQL, for example, to set default destination to: D:\MSSQLData

USE [master]

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultData', REG_SZ, N'D:\MSSQLData'

GO

EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', N'Software\Microsoft\MSSQLServer\MSSQLServer', N'DefaultLog', REG_SZ, N'D:\MSSQLData'

GO

I think this other Stack Overflow answer would solve your problem: How do I run a bat file in the background from another bat file?

Basically, you use the /B and /C options:

START /B CMD /C CALL "foo.bat" [args [...]] >NUL 2>&1

This worked for me:

In my CSS I have:

tab0  { position:absolute;left:25px;  }
tab1  { position:absolute;left:50px;  }
tab2  { position:absolute;left:75px;  }
tab3  { position:absolute;left:100px; }
tab4  { position:absolute;left:125px; }
tab5  { position:absolute;left:150px; }
tab6  { position:absolute;left:175px; }
tab7  { position:absolute;left:200px; }
tab8  { position:absolute;left:225px; }
tab9  { position:absolute;left:250px; }
tab10 { position:absolute;left:275px; }

Then in the HTML I just use my tabs:

Dog Food <tab3> :$30
Milk <tab3> :$3
Pizza Kit <tab3> :$5
Mt Dew <tab3> :$1.75

I've just found this solution:

if(@getimagesize($remoteImageURL)){
    //image exists!
}else{
    //image does not exist.

Use setFinishOnTouchOutside(false) for API > 11 and don't worry because its android's default behavior that activity themed dialog won't get finished on outside touch for API < 11 :) !!Cheerss!!

Current answers are either incomplete or inefficient. Here is (perhaps) the shortest way to achieve the outcome (using theme_void():

data(diamonds) # Data example
ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut)) +
      theme_void() + theme(legend.position="none")

The outcome is:

If you are interested in just eliminating the labels, labs(x="", y="") does the trick:

ggplot(data = diamonds, mapping = aes(x = clarity)) + geom_bar(aes(fill = cut)) + 
      labs(x="", y="")

Asking for the difference /between/ two commits without including the commits in-between makes little sense. Commits are just snapshots of the contents of the repository; asking for the difference between two necessarily includes them. So the question then is, what are you really looking for?

As William suggested, cherry-picking can give you the delta of a single commit rebased on top of another. That is:

$ git checkout 012345
$ git cherry-pick -n abcdef
$ git diff --cached

This takes commit 'abcdef', compares it to its immediate ancestor, then applies that difference on top of '012345'. This new difference is then shown - the only change is the context comes from '012345' rather than 'abcdef's immediate ancestor. Of course, you may get conflicts and etc, so it's not a very useful process in most cases.

If you're just interested in abcdef itself, you can do:

$ git log -u -1 abcdef

This compares abcdef to its immediate ancestor, alone, and is usually what you want.

And of course

$ git diff 012345..abcdef

gives you all differences between those two commits.

It would help to get a better idea of what you're trying to achieve - as I mentioned, asking for the difference between two commits without what's in between doesn't actually make sense.

There is a getch() function in the ncurses library. You can get it by installing the ncurses-dev package.

Simple (Demo):

function sortedIndex(array, value) {
    var low = 0,
        high = array.length;

    while (low < high) {
        var mid = (low + high) >>> 1;
        if (array[mid] < value) low = mid + 1;
        else high = mid;
    }
    return low;
}

Following the steps will make it 10 times faster and reduce build time 90%

First create a file named gradle.properties in the following directory:

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

Add this line to the file:

org.gradle.daemon=true

org.gradle.parallel=true

In Excel, you can set a Range.NumberFormat to any string as you would find in the "Custom" format selection. Essentially, you have two choices:

1. General for no particular format.
2. A custom formatted string, like "$#,##0", to specify exactly what format you're using.

I have observed on Windows 2008 the Windows Error Reporting crash dumps get staged in the folder:

C:\Users\All Users\Microsoft\Windows\WER\ReportQueue

Which, starting with Windows Vista, is an alias for:

C:\ProgramData\Microsoft\Windows\WER\ReportQueue

If you want to know how many files and sub-directories exist from the present working directory you can use this one-liner

find . -maxdepth 1 -type d -print0 | xargs -0 -I {} sh -c 'echo -e $(find {} | wc -l) {}' | sort -n

This will work in GNU flavour, and just omit the -e from the echo command for BSD linux (e.g. OSX).

easy.

Have you tried the __name__ attribute of the class? ie type(x).__name__ will give you the name of the class, which I think is what you want.

>>> import itertools
>>> x = itertools.count(0)
>>> type(x).__name__
'count'

If you're still using Python 2, note that the above method works with new-style classes only (in Python 3+ all classes are "new-style" classes). Your code might use some old-style classes. The following works for both:

x.__class__.__name__

if you are looking for a boolean, the quickest way would be

var values = [_x000D_
    { name: 'someName1' },_x000D_
    { name: 'someName2' },_x000D_
    { name: 'someName1' },_x000D_
    { name: 'someName1' }_x000D_
]_x000D_
_x000D_
// solution_x000D_
var hasDuplicate = false;_x000D_
values.map(v => v.name).sort().sort((a, b) => {_x000D_
  if (a === b) hasDuplicate = true_x000D_
})_x000D_
console.log('hasDuplicate', hasDuplicate)

earl's answer gives you the solution, but I thought I'd add what the problem is that's causing your IllegalStateException. You're calling group(1) without having first called a matching operation (such as find()). This isn't needed if you're just using $1 since the replaceAll() is the matching operation.

Maybe will be useful for someone.
When you login to any user of any console/terminal history of your current session exists only in some "buffer" which flushes to ~/.bash_history on your logout.
So, to keep things secret you can just:
history -r && exit
and you will be logged out with all your session's (and only) history cleared ;)

Your question and code sample are a little vague, and I believe the other developers are focusing on the wrong thing. I am making an application in Laravel, have used online tutorials for creating a new user and authentication, and seemed to have noticed that when you create a new user in Laravel, no Auth object is created - which you use to get the (new) logged-in user's ID in the rest of the application. This is a problem, and I believe what you may be asking. I did this kind of cludgy hack in userController::store :

$user->save();

Session::flash('message','Successfully created user!');

//KLUDGE!! rest of site depends on user id in auth object - need to force/create it here
Auth::attempt(array('email' => Input::get('email'), 'password' => Input::get('password')), true);

Redirect::to('users/' . Auth::user()->id);

Shouldn't have to create and authenticate, but I didn't know what else to do.

I had a very long path, and there's a file in there somewhere (not gcc.exe) but another file, that gcc.exe is accessing from the path..

So when I cleared the path, it worked

C:\MinGW>cd bin


C:\MinGW\bin>where gcc.exe
C:\MinGW\bin\gcc.exe
C:\Perl64\site\bin\gcc.exe

^^ So running gcc from there will definitely run the ming gcc.exe

C:\MinGW\bin>type file6.c
#include<stdio.h>
void main()
{
int num1,num2;
scanf("%2d %4d",&num1,&num2);
printf("a=%d b=%d",num1,num2);
scanf("%d",&num1);
//flushall();
printf("c=%d",num1);
}

Compiling it I got this error

C:\MinGW\bin>gcc file6.c
gcc: error: CreateProcess: No such file or directory

My PATH was huge

C:\MinGW\bin>path
PATH=C:\Windows\system32;C:\Windows;C:\Windows\system32\wbem;C:\P......

C:\MinGW\bin>path | grep -io "ming"

It didn't have ming there.

C:\MinGW\bin>echo MING | grep -io "ming" MING

(and yeah that grep works..the path didn't have ming there)

Clearing my path completely, led it to work!

C:\MinGW\bin>set PATH=

C:\MinGW\bin>gcc file6.c

C:\MinGW\bin>

So, it's not clear yet precisely what it was in the PATH that led to the clash. What directory, what file.

Update-

The above seems to be correct to me but to add, it's also not a simple case of something earlier in the path clashing.. because normally the current directory takes precedence. And it does here in so far as gcc --version shows it's running the ming one and not one of the ones in a conflicting directory. So there's something funny going on that, if the conflicting directory is in the path) , one has to either do .\gcc or add . to the start of the path or add c:\MinGW\bin before any conflicting directories in the path. this is the case even when you're in C:\MinGW\bin and that's strange. And when it gives an error, it is still running Ming's gcc but (For some reason) looking at the conflicting directory too, as I see from process monitor. There may be more of an answer here http://wiki.codeblocks.org/index.php?title=Installing_MinGW_with_Vista in the link mentioned in the very upvoted answer here

That's Ming32 bit..

Looking at Ming 64bit, probably has te same issue, but I see, interestingly, it comes with a bat file that (sensibly) actually puts the bin directory at the tart of the path. And it looks like that is a standard way of running Ming gcc properly.

The code::blocks IDE (sensibly) also puts the bin directory at the start of the path. If you run a C program that shows environment variables then you see that.

The deduplication (to select the max T1) and the aggregation need to be done as distinct steps. I've used a CTE since I think this makes it clearer:

;WITH sumCTE
AS
(
    SELECT  Rel.t2ID, SUM(Price) price
    FROM    @t1         AS T1
    JOIN    @relation   AS Rel 
    ON      Rel.t1ID=T1.ID
    GROUP 
    BY      Rel.t2ID
)
,maxCTE
AS
(
    SELECT  Rel.t2ID, Rel.t1ID, 
            ROW_NUMBER()OVER(Partition By Rel.t2ID Order By Price DESC)As PriceList
    FROM    @t1         AS T1
    JOIN    @relation   AS Rel 
    ON      Rel.t1ID=T1.ID
)
SELECT T2.ID AS T2ID
,T2.Name as T2Name
,T2.Orders
,T1.ID AS T1ID
,T1.Name As T1Name
,sumT1.Price
FROM    @t2 AS T2
JOIN    sumCTE AS sumT1
ON      sumT1.t2ID = t2.ID
JOIN    maxCTE AS maxT1
ON      maxT1.t2ID = t2.ID
JOIN    @t1 AS T1
ON      T1.ID = maxT1.t1ID
WHERE   maxT1.PriceList = 1

If the value stored in PropertyLoader.RET_SECONDARY_V_ARRAY is not "V_ARRAY", then you are using different types; even if they are declared identically (e.g. both are table of number) this will not work.

You're hitting this data type compatibility restriction:

You can assign a collection to a collection variable only if they have the same data type. Having the same element type is not enough.

You're trying to call the procedure with a parameter that is a different type to the one it's expecting, which is what the error message is telling you.

TL;DR

Markdown doesn't support color but you can inline HTML inside Markdown, e.g.:

<span style="color:blue">some *blue* text</span>.

Longer answer

As the original/official syntax rules state (emphasis added):

Markdown’s syntax is intended for one purpose: to be used as a format for writing for the web.

Markdown is not a replacement for HTML, or even close to it. Its syntax is very small, corresponding only to a very small subset of HTML tags. The idea is not to create a syntax that makes it easier to insert HTML tags. In my opinion, HTML tags are already easy to insert. The idea for Markdown is to make it easy to read, write, and edit prose. HTML is a publishing format; Markdown is a writing format. Thus, Markdown’s formatting syntax only addresses issues that can be conveyed in plain text.

For any markup that is not covered by Markdown’s syntax, you simply use HTML itself.

As it is not a "publishing format," providing a way to color your text is out-of-scope for Markdown. That said, it is not impossible as you can include raw HTML (and HTML is a publishing format). For example, the following Markdown text (as suggested by @scoa in a comment):

Some Markdown text with <span style="color:blue">some *blue* text</span>.

Would result in the following HTML:

<p>Some Markdown text with <span style="color:blue">some <em>blue</em> text</span>.</p>

Now, StackOverflow (and probably GitHub) will strip the raw HTML out (as a security measure) so you lose the color here, but it should work on any standard Markdown implementation.

Another possibility is to use the non-standard Attribute Lists originally introduced by the Markuru implementation of Markdown and later adopted by a few others (there may be more, or slightly different implementations of the same idea, like div and span attributes in pandoc). In that case, you could assign a class to a paragraph or inline element, and then use CSS to define a color for a class. However, you absolutely must be using one of the few implementations which actually support the non-standard feature and your documents are no longer portable to other systems.

If you want to ignore lines with only whitespace:

if not line.strip():
    ... do something

The empty string is a False value.

Or if you really want only empty lines:

if line in ['\n', '\r\n']:
    ... do  something

You can just use the pipe on its own:

"string1|string2"

for example:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|string2", "blah"));

Output:

blah, blah, string3

The main reason to use parentheses is to limit the scope of the alternatives:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(1|2)", "blah"));

has the same output. but if you just do this:

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string1|2", "blah"));

you get:

blah, stringblah, string3

because you've said "string1" or "2".

If you don't want to capture that part of the expression use ?::

String s = "string1, string2, string3";
System.out.println(s.replaceAll("string(?:1|2)", "blah"));

If you frequently use a large number of exceptions, you can pre-define a tuple, so you don't have to re-type them many times.

#This example code is a technique I use in a library that connects with websites to gather data

ConnectErrs  = (URLError, SSLError, SocketTimeoutError, BadStatusLine, ConnectionResetError)

def connect(url, data):
    #do connection and return some data
    return(received_data)

def some_function(var_a, var_b, ...):
    try: o = connect(url, data)
    except ConnectErrs as e:
        #do the recovery stuff
    blah #do normal stuff you would do if no exception occurred

NOTES:

1. If you, also, need to catch other exceptions than those in the pre-defined tuple, you will need to define another except block.

2. If you just cannot tolerate a global variable, define it in main() and pass it around where needed...

You should also consider the OPTIMIZE FOR n ROWS clause. More details on all of this in the DB2 LUW documentation in the Guidelines for restricting SELECT statements topic:

• The OPTIMIZE FOR clause declares the intent to retrieve only a subset of the result or to give priority to retrieving only the first few rows. The optimizer can then choose access plans that minimize the response time for retrieving the first few rows.

{
  "data": {
    "__type": {
      "fields": [
        {
          "name": "id",
          "description": ""
        },
        {
          "name": "username",
          "description": "Required. 150 characters or fewer. Letters, digits and @/./+/-/_ only."
        },
        {
          "name": "firstName",
          "description": ""
        },
        {
          "name": "lastName",
          "description": ""
        },
        {
         "name": "email",
          "description": ""
        },
        ( etc. etc. ...)
      ]
    }
  }
}

You can then read this list of fields in your client and dynamically build a second GraphQL query to get all of these fields.

This relies on you knowing the name of the type that you want to get the fields for -- if you don't know the type, you could get all the types and fields together using introspection like

{
  __schema {
    types {
      name
      fields {
        name
        description
      }
    }
  }
}

NOTE: this is the over-the-wire GraphQL data -- you're on your own to figure out how to read and write with your actual client. Your graphQL javascript library may already employ introspection in some capacity, for example the apollo codegen command uses introspection to generate types.

This is not a compiler error: the error is coming from the linker. After compilation, the linker will merge the object files resulting from the compilation of each of your translation units (.cpp files).

The linker finds out that you have the same symbol defined multiple times in different translation units, and complains about it (it is a violation of the One Definition Rule).

The reason is most certainly that main.cpp includes client.cpp, and both these files are individually processed by the compiler to produce two separate object files. Therefore, all the symbols defined in the client.cpp translation unit will be defined also in the main.cpp translation unit. This is one of the reasons why you do not usually #include .cpp files.

Put the definition of your class in a separate client.hpp file which does not contain also the definitions of the member functions of that class; then, let client.cpp and main.cpp include that file (I mean #include). Finally, leave in client.cpp the definitions of your class's member functions.

client.h

#ifndef SOCKET_CLIENT_CLASS
#define SOCKET_CLIENT_CLASS
#ifndef BOOST_ASIO_HPP
#include <boost/asio.hpp>
#endif

class SocketClient // Or whatever the name is...
{

// ...

    bool read(int, char*); // Or whatever the name is...

//  ...
};

#endif

client.cpp

#include "Client.h"

// ...

bool SocketClient::read(int, char*)
{
    // Implementation  goes here...
}

// ... (add the definitions for all other member functions)

main.h

#include <iostream>
#include <string>
#include <sstream>
#include <boost/asio.hpp>
#include <boost/thread/thread.hpp>
#include "client.h"
//              ^^ Notice this!

main.cpp

#include "main.h"

Minimal reproduction example with disassembly analysis

main.c

void myfunc(char *const src, int len) {
    int i;
    for (i = 0; i < len; ++i) {
        src[i] = 42;
    }
}

int main(void) {
    char arr[] = {'a', 'b', 'c', 'd'};
    int len = sizeof(arr);
    myfunc(arr, len + 1);
    return 0;
}

GitHub upstream.

Compile and run:

gcc -fstack-protector-all -g -O0 -std=c99 main.c
ulimit -c unlimited && rm -f core
./a.out

fails as desired:

*** stack smashing detected ***: terminated
Aborted (core dumped)

Tested on Ubuntu 20.04, GCC 10.2.0.

On Ubuntu 16.04, GCC 6.4.0, I could reproduce with -fstack-protector instead of -fstack-protector-all, but it stopped blowing up when I tested on GCC 10.2.0 as per Geng Jiawen's comment. man gcc clarifies that as suggested by the option name, the -all version adds checks more aggressively, and therefore presumably incurs a larger performance loss:

-fstack-protector

Emit extra code to check for buffer overflows, such as stack smashing attacks. This is done by adding a guard variable to functions with vulnerable objects. This includes functions that call "alloca", and functions with buffers larger than or equal to 8 bytes. The guards are initialized when a function is entered and then checked when the function exits. If a guard check fails, an error message is printed and the program exits. Only variables that are actually allocated on the stack are considered, optimized away variables or variables allocated in registers don't count.

-fstack-protector-all

Like -fstack-protector except that all functions are protected.

Disassembly

Now we look at the disassembly:

objdump -D a.out

which contains:

Notice the handy comments automatically added by objdump's artificial intelligence module.

If you run this program multiple times through GDB, you will see that:

• the canary gets a different random value every time
• the last loop of myfunc is exactly what modifies the address of the canary

The canary randomized by setting it with %fs:0x28, which contains a random value as explained at:

• https://unix.stackexchange.com/questions/453749/what-sets-fs0x28-stack-canary
• Why does this memory address %fs:0x28 ( fs[0x28] ) have a random value?

Debug attempts

From now on, we modify the code:

    myfunc(arr, len + 1);

to be instead:

    myfunc(arr, len);
    myfunc(arr, len + 1); /* line 12 */
    myfunc(arr, len);

to be more interesting.

We will then try to see if we can pinpoint the culprit + 1 call with a method more automated than just reading and understanding the entire source code.

gcc -fsanitize=address to enable Google's Address Sanitizer (ASan)

If you recompile with this flag and run the program, it outputs:

#0 0x4008bf in myfunc /home/ciro/test/main.c:4
#1 0x40099b in main /home/ciro/test/main.c:12
#2 0x7fcd2e13d82f in __libc_start_main (/lib/x86_64-linux-gnu/libc.so.6+0x2082f)
#3 0x400798 in _start (/home/ciro/test/a.out+0x40079

followed by some more colored output.

This clearly pinpoints the problematic line 12.

The source code for this is at: https://github.com/google/sanitizers but as we saw from the example it is already upstreamed into GCC.

ASan can also detect other memory problems such as memory leaks: How to find memory leak in a C++ code/project?

Valgrind SGCheck

As mentioned by others, Valgrind is not good at solving this kind of problem.

It does have an experimental tool called SGCheck:

SGCheck is a tool for finding overruns of stack and global arrays. It works by using a heuristic approach derived from an observation about the likely forms of stack and global array accesses.

So I was not very surprised when it did not find the error:

valgrind --tool=exp-sgcheck ./a.out

The error message should look like this apparently: Valgrind missing error

GDB

An important observation is that if you run the program through GDB, or examine the core file after the fact:

gdb -nh -q a.out core

then, as we saw on the assembly, GDB should point you to the end of the function that did the canary check:

(gdb) bt
#0  0x00007f0f66e20428 in __GI_raise (sig=sig@entry=6) at ../sysdeps/unix/sysv/linux/raise.c:54
#1  0x00007f0f66e2202a in __GI_abort () at abort.c:89
#2  0x00007f0f66e627ea in __libc_message (do_abort=do_abort@entry=1, fmt=fmt@entry=0x7f0f66f7a49f "*** %s ***: %s terminated\n") at ../sysdeps/posix/libc_fatal.c:175
#3  0x00007f0f66f0415c in __GI___fortify_fail (msg=<optimized out>, msg@entry=0x7f0f66f7a481 "stack smashing detected") at fortify_fail.c:37
#4  0x00007f0f66f04100 in __stack_chk_fail () at stack_chk_fail.c:28
#5  0x00000000004005f6 in main () at main.c:15
(gdb) f 5
#5  0x00000000004005f6 in main () at main.c:15
15      }
(gdb)

And therefore the problem is likely in one of the calls that this function made.

Next we try to pinpoint the exact failing call by first single stepping up just after the canary is set:

  400581:       64 48 8b 04 25 28 00    mov    %fs:0x28,%rax
  400588:       00 00 
  40058a:       48 89 45 f8             mov    %rax,-0x8(%rbp)

and watching the address:

(gdb) p $rbp - 0x8
$1 = (void *) 0x7fffffffcf18
(gdb) watch 0x7fffffffcf18
Hardware watchpoint 2: *0x7fffffffcf18
(gdb) c
Continuing.

Hardware watchpoint 2: *0x7fffffffcf18

Old value = 1800814336
New value = 1800814378
myfunc (src=0x7fffffffcf14 "*****?Vk\266", <incomplete sequence \355\216>, len=5) at main.c:3
3           for (i = 0; i < len; ++i) {
(gdb) p len
$2 = 5
(gdb) p i
$3 = 4
(gdb) bt
#0  myfunc (src=0x7fffffffcf14 "*****?Vk\266", <incomplete sequence \355\216>, len=5) at main.c:3
#1  0x00000000004005cc in main () at main.c:12

Now, this does leaves us at the right offending instruction: len = 5 and i = 4, and in this particular case, did point us to the culprit line 12.

However, the backtrace is corrupted, and contains some trash. A correct backtrace would look like:

#0  myfunc (src=0x7fffffffcf14 "abcd", len=4) at main.c:3
#1  0x00000000004005b8 in main () at main.c:11

so maybe this could corrupt the stack and prevent you from seeing the trace.

Also, this method requires knowing what is the last call of the canary checking function otherwise you will have false positives, which will not always be feasible, unless you use reverse debugging.

You need to change || to && so that both conditions must be true to enter the loop.

while(myChar != 'n' && myChar != 'N')

I think you can use the nrows parameter. From the docs:

nrows : int, default None

    Number of rows of file to read. Useful for reading pieces of large files

which seems to work. Using one of the standard large test files (988504479 bytes, 5344499 lines):

In [1]: import pandas as pd

In [2]: time z = pd.read_csv("P00000001-ALL.csv", nrows=20)
CPU times: user 0.00 s, sys: 0.00 s, total: 0.00 s
Wall time: 0.00 s

In [3]: len(z)
Out[3]: 20

In [4]: time z = pd.read_csv("P00000001-ALL.csv")
CPU times: user 27.63 s, sys: 1.92 s, total: 29.55 s
Wall time: 30.23 s

eval(s);

But this can be dangerous if you are taking data from users, although I suppose if they crash their own browser thats their problem.

Can with defaulth value (T-SQL)

ALTER TABLE
    Regions
ADD
    HasPhotoInReadyStorage BIT NULL, --this column is nullable
    HasPhotoInWorkStorage BIT NOT NULL, --this column is not nullable
    HasPhotoInMaterialStorage BIT NOT NULL DEFAULT(0) --this column default value is false
GO

Building on Rene's answer, you could also write a function that returned either TRUE if the substring was present, or FALSE if it wasn't:

Public Function Contains(strBaseString As String, strSearchTerm As String) As Boolean
'Purpose: Returns TRUE if one string exists within another
On Error GoTo ErrorMessage
    Contains = InStr(strBaseString, strSearchTerm)
Exit Function
ErrorMessage:
MsgBox "The database has generated an error. Please contact the database administrator, quoting the following error message: '" & Err.Description & "'", vbCritical, "Database Error"
End
End Function

I played with this two weeks ago, it's very simple. The only problem is that all the tutorials just talk about saving the image locally. This is how I did it:

1) I set up a form so I can use a POST method.

2) When the user is done drawing, he can click the "Save" button.

3) When the button is clicked I take the image data and put it into a hidden field. After that I submit the form.

document.getElementById('my_hidden').value = canvas.toDataURL('image/png');
document.forms["form1"].submit();

4) When the form is submited I have this small php script:

<?php 
$upload_dir = somehow_get_upload_dir();  //implement this function yourself
$img = $_POST['my_hidden'];
$img = str_replace('data:image/png;base64,', '', $img);
$img = str_replace(' ', '+', $img);
$data = base64_decode($img);
$file = $upload_dir."image_name.png";
$success = file_put_contents($file, $data);
header('Location: '.$_POST['return_url']);
?>

Only people from Microsoft can really answer that question. However, I'd like to offer some fun facts about it ;)

First, this is what it says in MSDN about the Boolean.ToString() method:

Return Value

Type: System.String

TrueString if the value of this instance is true, or FalseString if the value of this instance is false.

Remarks

This method returns the constants "True" or "False". Note that XML is case-sensitive, and that the XML specification recognizes "true" and "false" as the valid set of Boolean values. If the String object returned by the ToString() method is to be written to an XML file, its String.ToLower method should be called first to convert it to lowercase.

Here comes the fun fact #1: it doesn't return TrueString or FalseString at all. It uses hardcoded literals "True" and "False". Wouldn't do you any good if it used the fields, because they're marked as readonly, so there's no changing them.

The alternative method, Boolean.ToString(IFormatProvider) is even funnier:

Remarks

The provider parameter is reserved. It does not participate in the execution of this method. This means that the Boolean.ToString(IFormatProvider) method, unlike most methods with a provider parameter, does not reflect culture-specific settings.

What's the solution? Depends on what exactly you're trying to do. Whatever it is, I bet it will require a hack ;)

File > Site Manager > Select your site > Transfer Settings > Active

Works for me.

This only converts the tabs without changing anything else:

Edit -> Convert Indents -> To Spaces

You have to specify the folder where you are saving it and it has to exist, in other case it will throw an error.

var s = txt.CreateTextFile("c:\\11.txt", true);

For those using beta versions of Xcode, just change the application name in the command to Xcode-beta.app:

cd ~
mv .itmstransporter/ .old_itmstransporter/
"/Applications/Xcode-beta.app/Contents/Applications/Application Loader.app/Contents/itms/bin/iTMSTransporter"

Depending on your internet connection, the update may take some time. For me it was around 15 minutes.

Easiest is by using FileUtils from Apache commons-io.( https://commons.apache.org/proper/commons-io/javadocs/api-2.5/org/apache/commons/io/FileUtils.html )

Returns human readable file size from Bytes to Exabytes , rounding down to the boundary.

File fileObj = new File(filePathString);
String fileSizeReadable = FileUtils.byteCountToDisplaySize(fileObj.length());

// output will be like 56 MB 

To interact with the box you need to update the state for the checkbox once you change it. And to have a default setting you can use defaultChecked.

An example:

<input type="checkbox" defaultChecked={this.state.chkbox} onChange={this.handleChangeChk} />

This can be accomplished by Unmarshaling into a map[string]json.RawMessage.

var objmap map[string]json.RawMessage
err := json.Unmarshal(data, &objmap)

To further parse sendMsg, you could then do something like:

var s sendMsg
err = json.Unmarshal(objmap["sendMsg"], &s)

For say, you can do the same thing and unmarshal into a string:

var str string
err = json.Unmarshal(objmap["say"], &str)

EDIT: Keep in mind you will also need to export the variables in your sendMsg struct to unmarshal correctly. So your struct definition would be:

type sendMsg struct {
    User string
    Msg  string
}

Example: https://play.golang.org/p/OrIjvqIsi4-

is that what you are looking for:

URI uri = new URI("http://example.com/foo/bar/42?param=true");
String path = uri.getPath();
String idStr = path.substring(path.lastIndexOf('/') + 1);
int id = Integer.parseInt(idStr);

alternatively

URI uri = new URI("http://example.com/foo/bar/42?param=true");
String[] segments = uri.getPath().split("/");
String idStr = segments[segments.length-1];
int id = Integer.parseInt(idStr);

Try moving the OGG source to the top. I've noticed Firefox sometimes gets confused and stops the player when the one it wants to play, OGG, isn't first.

Worth a try.

Don't forget to return the mapped array , like:

lapsList() {

    return this.state.laps.map((data) => {
      return (
        <View><Text>{data.time}</Text></View>
      )
    })

}

Reference for the map() method: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/map

The general idea is to sweep the function across. You have many options, one is apply():

R> set.seed(42)
R> M <- matrix(rnorm(40),ncol=4)
R> apply(M, 2, sd)
[1] 0.835449 1.630584 1.156058 1.115269
R> 

To remove disabled attribute use,

 $("#elementID").removeAttr('disabled');

and to add disabled attribute use,

$("#elementID").prop("disabled", true);

Enjoy :)

In .NET you can use grouping to your advantage like this:

http://regexhero.net/tester/?id=65b32601-2326-4ece-912b-6dcefd883f31

You'll notice that:

(ABC)|(.)

Will grab everything except ABC in the 2nd group. Parenthesis surround each group. So (ABC) is group 1 and (.) is group 2.

So you just grab the 2nd group like this in a replace:

$2

Or in .NET look at the Groups collection inside the Regex class for a little more control.

You should be able to do something similar in most other regex implementations as well.

UPDATE: I found a much faster way to do this here: http://regexhero.net/tester/?id=997ce4a2-878c-41f2-9d28-34e0c5080e03

It still uses grouping (I can't find a way that doesn't use grouping). But this method is over 10X faster than the first.

This is how it worked for me :

df= pd.DataFrame([d.keys(), d.values()]).T
df.columns= ['keys', 'values']  # call them whatever you like

I hope this helps

I had the same issue and I have gone through all these solutions given, but none of them worked for me. But then I realised my stupid mistake. I forgot to change Code signing identity to iOS Distribution from iOS Developer, under build settings tab. Please make sure you have selected 'iOS Distribution' there.

I found a solution to this. It's bloody witchcraft, but it works.

When you install the client, open Control Panel > Network Connections.

You'll see a disabled network connection that was added by the TAP installer (Local Area Connection 3 or some such).

Right Click it, click Enable.

The device will not reset itself to enabled, but that's ok; try connecting w/ the client again. It'll work.

window.onbeforeunload = function () {
    return "Do you really want to close?";
};

There's no easy way to do this, but something like this will work:

SELECT ET.TrainingID, 
  ET.CompletedDate, 
  ET.Notes
FROM 
HR_EmployeeTrainings ET
inner join
(
  select TrainingID, Max(CompletedDate) as CompletedDate
  FROM HR_EmployeeTrainings
  WHERE (ET.AvantiRecID IS NULL OR ET.AvantiRecID = @avantiRecID)
  GROUP BY AvantiRecID, TrainingID  
) ET2 
  on ET.TrainingID = ET2.TrainingID
  and ET.CompletedDate = ET2.CompletedDate

I write these 2 functions to make my life easier:

function scrollToTop(elem, parent, speed) {
    var scrollOffset = parent.scrollTop() + elem.offset().top;
    parent.animate({scrollTop:scrollOffset}, speed);
    // parent.scrollTop(scrollOffset, speed);
}

function scrollToCenter(elem, parent, speed) {
    var elOffset = elem.offset().top;
    var elHeight = elem.height();
    var parentViewTop = parent.offset().top;
    var parentHeight = parent.innerHeight();
    var offset;

    if (elHeight >= parentHeight) {
        offset = elOffset;
    } else {
        margin = (parentHeight - elHeight)/2;
        offset = elOffset - margin;
    }

    var scrollOffset = parent.scrollTop() + offset - parentViewTop;

    parent.animate({scrollTop:scrollOffset}, speed);
    // parent.scrollTop(scrollOffset, speed);
}

And use them:

scrollToTop($innerListItem, $parentDiv, 200);
// or
scrollToCenter($innerListItem, $parentDiv, 200);

You can use PyInstaller to package Python programs as standalone executables. It works on Windows, Linux, and Mac.

pip install pyinstaller

Go to your program’s directory and run:

pyinstaller yourprogram.py

This will generate the bundle in a subdirectory called dist.

For a more detailed walkthrough, see the manual.

This issue happens when you reference a .NET Standard project from a .NET 4.x project: none of the .NET Standard project's nuget package references are brought in as dependencies.

To fix this, you need to ensure your .NET 4.x csproj file is pointing to current build tools (at least 14):

<Project ToolsVersion="15.0">...

The below should no longer be needed, it was fixed around VS 15.3:

There was a known bug in VS2017, specifically in NuGet 4.0.

To work around the bug, you'll need to open up the .csproj file for your .NET 4.x project and add this snippet:

<ItemGroup>
  <PackageReference Include="Legacy2CPSWorkaround" Version="1.0.0">
    <PrivateAssets>All</PrivateAssets>
  </PackageReference>
</ItemGroup>

NuGet 4.x brings with it the "package reference" -- no more packages.config -- but the old 4.x pipeline was not fully updated at the time of VS2017's launch. The above snippet seems to "wake up" the build system to correctly include package references from dependencies.

Override ui-page class in your css:

.ui-page {
    background: url("image.gif");
    background-repeat: repeat;
}

Once you've installed MySQL, you'll need to establish the "root" password. If you don't establish a root password, then, well, there is no root password, and you don't need a password to log in.

So, that being said, you need to establish a root password.

Using terminal enter the following:

Installation: Set root user password:

/usr/local/mysql/bin/mysqladmin -u root password NEW_PASSWORD_HERE

If you've made a mistake, or need to change the root password use the following:

Change root password:

cd /usr/local/mysql/bin/
./mysql -u root -p
> Enter password: [type old password invisibly]

use mysql;
update user set password=PASSWORD("NEW_PASSWORD_HERE") where User='root';
flush privileges;
quit

An easy foolproof way to UNDO local file changes since the last commit is to place them in a new branch:

git branch changes
git checkout changes
git add .
git commit

This leaves the changes in the new branch. Return to the original branch to find it back to the last commit:

git checkout master

The new branch is a good place to practice different ways to revert changes without risk of messing up the original branch.

There is also another way if you define one pointcut for many advices it can be helpful:

@Pointcut("execution(@com.stackoverflow.MyAnnotation * *(..))")
protected void myPointcut() {
}

@AfterThrowing(pointcut = "myPointcut() && args(someId,..)", throwing = "e")
public void afterThrowingException(JoinPoint joinPoint, Exception e, Integer someId) {
    System.out.println(someId.toString());
}

@AfterReturning(pointcut = "myPointcut() && args(someId,..)")
public void afterSuccessfulReturn(JoinPoint joinPoint, Integer someId) {
    System.out.println(someId.toString());
}

I would suggest the method presented on the Gradle forum:

def createMinifyCssTask(def brand, def sourceFile, def destFile) {
    return tasks.create("minify${brand}Css", com.eriwen.gradle.css.tasks.MinifyCssTask) {
        source = sourceFile
        dest = destFile
    }
}

I have used this method myself to create custom tasks, and it works very well.

df[df.col.str.contains("foo").fillna(False)]

As described in issue 6255:

use '**./**model_name.ckpt'
saver.restore(sess,'./my_model_final.ckpt')

instead of

saver.restore('my_model_final.ckpt')

You can create a config class witch static properties

class Config 
{
    static $dbHost = 'localhost';
    static $dbUsername = 'user';
    static $dbPassword  = 'pass';
}

then you can simple use it:

Config::$dbHost  

Sometimes in my projects I use a design pattern SINGLETON to access configuration data. It's very comfortable in use.

Why?

For example you have 2 data source in your project. And you can choose witch of them is enabled.

• mysql
• json

Somewhere in config file you choose:

$dataSource = 'mysql' // or 'json'

When you change source whole app shoud switch to new data source, work fine and dont need change in code.

Example:

Config:

class Config 
{
  // ....
  static $dataSource = 'mysql';
  / .....
}

Singleton class:

class AppConfig
{
    private static $instance;
    private $dataSource;

    private function __construct()
    {
        $this->init();
    }

    private function init()
    {
        switch (Config::$dataSource)
        {
            case 'mysql':
                $this->dataSource = new StorageMysql();
                break;
            case 'json':
                $this->dataSource = new StorageJson();
                break;
            default:
                $this->dataSource = new StorageMysql();
        }
    }

    public static function getInstance()
    {
        if (empty(self::$instance)) {
            self::$instance = new self();
        }
        return self::$instance;
    }

    public function getDataSource()
    {
        return $this->dataSource;
    }
}

... and somewhere in your code (eg. in some service class):

$container->getItemsLoader(AppConfig::getInstance()->getDataSource()) // getItemsLoader need Object of specific data source class by dependency injection

We can obtain an AppConfig object from any place in the system and always get the same copy (thanks to static). The init () method of the class is called In the constructor, which guarantees only one execution. Init() body checks The value of the config $dataSource, and create new object of specific data source class. Now our script can get object and operate on it, not knowing even which specific implementation actually exists.

In my case, the accepted answer didn't work:

f.sort_values(by=["c1","c2"], ascending=[False, True])

Only the following worked as expected:

f = f.sort_values(by=["c1","c2"], ascending=[False, True])

May be, it is not the very worst idea to merge (via difftool) from ... yes ... a branch!

> current_branch=$(git status | head -n1 | cut -d' ' -f3)
> stash_branch="$current_branch-stash-$(date +%yy%mm%dd-%Hh%M)"
> git stash branch $stash_branch
> git checkout $current_branch
> git difftool $stash_branch

Since AngularJS does not have directive DOM manipulations as jQuery does, a proper way to modify attributes of one element will be using directive. Through link function of a directive, you have access to both element and its attributes.

Wrapping you whole input inside one directive, you can still introduce ng-model's methods through controller property.

This method will help to decouple the logic of ngmodel with placeholder from controller. If there is no logic between them, you can definitely go as Wagner Francisco said.

A few years late, but I have a solution for the most recent version of WordPress, which has this same issue (WordPress-generated .htaccess files break sites, reuslting in 403 Forbidden error messages). Here's that it looks like when WordPress creates it:

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

The problem is that the conditional doesn't work. It doesn't work because the module it's looking for isn't .c, it's .so. I think this is a platform-specific, or configuration-specific issue, where Mac OS and Lunix Apache installations are set up for .so AKA 'shared-object' modules. Looking for a .c module shouldn't break the conditional, I think that's a bug, but it's the issue.

Simply change the mod_rewrite.c to mod_rewrite.so and you're all set to go!

# BEGIN WordPress
<IfModule mod_rewrite.so>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]
</IfModule>

# END WordPress

After trying many different ways, re-installing IIS on my windows solved the problem.

The shortest version.

startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com")));

Here's a similar system for the situation where you have a variable you want to sort by, initially, but then you want to sort by a secondary variable according to the order that this secondary variable first appears in the initial sort.

In the function below, the initial sort variable is called order_by and the secondary variable is called order_along - as in "order by this variable along its initial order".

library(dplyr, warn.conflicts = FALSE)
df <- structure(
  list(
    msoa11hclnm = c(
      "Bewbush", "Tilgate", "Felpham",
      "Selsey", "Brunswick", "Ratton", "Ore", "Polegate", "Mile Oak",
      "Upperton", "Arundel", "Kemptown"
    ),
    lad20nm = c(
      "Crawley", "Crawley",
      "Arun", "Chichester", "Brighton and Hove", "Eastbourne", "Hastings",
      "Wealden", "Brighton and Hove", "Eastbourne", "Arun", "Brighton and Hove"
    ),
    shape_area = c(
      1328821, 3089180, 3540014, 9738033, 448888, 10152663, 5517102,
      7036428, 5656430, 2653589, 72832514, 826151
    )
  ),
  row.names = c(NA, -12L), class = "data.frame"
)

this does not give me what I need:

df %>% 
  dplyr::arrange(shape_area, lad20nm)
#>    msoa11hclnm           lad20nm shape_area
#> 1    Brunswick Brighton and Hove     448888
#> 2     Kemptown Brighton and Hove     826151
#> 3      Bewbush           Crawley    1328821
#> 4     Upperton        Eastbourne    2653589
#> 5      Tilgate           Crawley    3089180
#> 6      Felpham              Arun    3540014
#> 7          Ore          Hastings    5517102
#> 8     Mile Oak Brighton and Hove    5656430
#> 9     Polegate           Wealden    7036428
#> 10      Selsey        Chichester    9738033
#> 11      Ratton        Eastbourne   10152663
#> 12     Arundel              Arun   72832514

Here’s a function:

order_along <- function(df, order_along, order_by) {
  cols <- colnames(df)
  
  df <- df %>%
    dplyr::arrange({{ order_by }})
  
  df %>% 
    dplyr::select({{ order_along }}) %>% 
    dplyr::distinct() %>% 
    dplyr::full_join(df) %>% 
    dplyr::select(dplyr::all_of(cols))
  
}

order_along(df, lad20nm, shape_area)
#> Joining, by = "lad20nm"
#>    msoa11hclnm           lad20nm shape_area
#> 1    Brunswick Brighton and Hove     448888
#> 2     Kemptown Brighton and Hove     826151
#> 3     Mile Oak Brighton and Hove    5656430
#> 4      Bewbush           Crawley    1328821
#> 5      Tilgate           Crawley    3089180
#> 6     Upperton        Eastbourne    2653589
#> 7       Ratton        Eastbourne   10152663
#> 8      Felpham              Arun    3540014
#> 9      Arundel              Arun   72832514
#> 10         Ore          Hastings    5517102
#> 11    Polegate           Wealden    7036428
#> 12      Selsey        Chichester    9738033

You can try as follows:

//------ js/functions.js ------
export function square(x) {
    return x * x;
}
export function diag(x, y) {
    return sqrt(square(x) + square(y));
}

//------ js/main.js ------
import { square, diag } from './functions.js';
console.log(square(11)); // 121
console.log(diag(4, 3)); // 5

You can also import completely:

//------ js/main.js ------
import * as lib from './functions.js';
console.log(lib.square(11)); // 121
console.log(lib.diag(4, 3)); // 5

Normally we use ./fileName.js for importing own js file/module and fileName.js is used for importing package/library module

When you will include the main.js file to your webpage you must set the type="module" attribute as follows:

<script type="module" src="js/main.js"></script>

I recently switched from a core 2 @ 2.5 with 3gb of ram to an i7 @ 1.73 with 8gb ram (both systems ran Ubuntu 10.10) and the emulator runs at least twice as fast now. Throwing more hardware at it certainly does help.

My problem on git was the project permission configuration. I've fixed it by enable the "Container registry" in settings->general->Visibility, project features, permissions and enable Container Registry for my project (link):

Adding some info to the previous answer from @linusg :

sklearn keeps a release history of all its changes. Think of checking it from time to time. Here is the link to the documentation.

As you can see in the documentation for the version 0.18, a new module was created called model_selection. Therefore it didn't exist in previous versions.

Update sklearn and it will work !

i had the same issue, but I just typed export on top and erased the default one on the bottom. Scroll down and check the comments.

import React, { Component } from "react";

export class Counter extends Component { // type this  
export default Counter; // this is eliminated  

Interfaces are concerned with polymorphism which is inherently tied to object instances, not classes. Therefore static doesn't make sense in the context of an interface.

Use a binding, like in this example:

<a href="#new-search" data-bind="click:SearchManager.bind($data,'1')">
  Search Manager
</a>

var ViewModelStructure = function () {
    var self = this;
    this.SearchManager = function (search) {
        console.log(search);
    };
}();

Try:

With DependencedIncidents AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
),
lalala AS
(
    SELECT INC.[RecTime],INC.[SQL] AS [str] FROM
    (
        SELECT A.[RecTime] As [RecTime],X.[SQL] As [SQL] FROM [EventView] AS A 
        CROSS JOIN [Incident] AS X
            WHERE
                patindex('%' + A.[Col] + '%', X.[SQL]) > 0
    ) AS INC
)

And yes, you can reference common table expression inside common table expression definition. Even recursively. Which leads to some very neat tricks.

Use

implementation 'com.android.support:appcompat-v7:27.1.1'

Don't use like

implementation 'com.android.support:appcompat-v7:27.+'

It may give you an error and don't use an older version than this.

or event don't do like this

implementation 'com.android.support:appcompat-v7:27.1.1'
implementation 'com.android.support:design:27.1.1' 

etc... numbers of libraries and then

implementation 'com.android.support:appcompat-v7:27.+'

the same library but it has a different version, it can give you an error.

Nothing new here but married this answer with this answer and slightly refactored it so that even I understand what's going on:

public static class ExpressionExtensions
{
    public static Expression<Func<T, bool>> AndAlso<T>(this Expression<Func<T, bool>> expr1, Expression<Func<T, bool>> expr2)
    {
        ParameterExpression parameter1 = expr1.Parameters[0];
        var visitor = new ReplaceParameterVisitor(expr2.Parameters[0], parameter1);
        var body2WithParam1 = visitor.Visit(expr2.Body);
        return Expression.Lambda<Func<T, bool>>(Expression.AndAlso(expr1.Body, body2WithParam1), parameter1);
    }

    private class ReplaceParameterVisitor : ExpressionVisitor
    {
        private ParameterExpression _oldParameter;
        private ParameterExpression _newParameter;

        public ReplaceParameterVisitor(ParameterExpression oldParameter, ParameterExpression newParameter)
        {
            _oldParameter = oldParameter;
            _newParameter = newParameter;
        }

        protected override Expression VisitParameter(ParameterExpression node)
        {
            if (ReferenceEquals(node, _oldParameter))
                return _newParameter;

            return base.VisitParameter(node);
        }
    }
}
