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

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

rest2web is a simple tool that lets you build your website from a single template (or as many as you want), and keep the contents in reStructuredText.

Pygments

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, Wikis or other applications that need to prettify source code. See Using Pygments in reStructuredText documents.

Free Editors

While any plain text editor is suitable to write reStructuredText documents, some editors have better support than others.

Emacs

The Emacs support via rst-mode comes as part of the Docutils package under /docutils/tools/editors/emacs/rst.el

Vim

The vim-common package for that comes with most GNU/Linux distributions has reStructuredText syntax highlight and indentation support of reStructuredText out of the box:

• reStructuredText syntax highlighting mode for vim
• VST (Vim reStructured Text) is a plugin for Vim7 with folding for reStructuredText
• Riv.vim - fresh vim plugin for authoring rst and Sphinx doc
• Previm: Vim plugin for live previewing of reStructuredText and other mark up documents

Geany

Geany, a small and lightweight Integrated Development Environment include support for reStructuredText from version 0.12 (October 10, 2007).

Leo

Leo, an outlining editor for programmers, supports reStructuredText via rst-plugin or via "@auto-rst" nodes (it's not well-documented, but @auto-rst nodes allow editing rst files directly, parsing the structure into the Leo outline).

It also provides a way to preview the resulting HTML, in a "viewrendered" pane.

FTE

The FTE Folding Text Editor - a free (licensed under the GNU GPL) text editor for developers. FTE has a mode for reStructuredText support. It provides color highlighting of basic RSTX elements and special menu that provide easy way to insert most popular RSTX elements to a document.

PyK

PyK is a successor of PyEdit and reStInPeace, written in Python with the help of the Qt4 toolkit.

Eclipse

The Eclipse IDE with the ReST Editor plug-in provides support for editing reStructuredText files.

NoTex

NoTex is a browser based (general purpose) text editor, with integrated project management and syntax highlighting. Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Visual Studio Code

Visual Studio Code is a general purpose text editor for Windows/macOS/Linux. It has syntax highlighting for many languages built-in and supports reStructuredText via an extension from LeXtudio.

Dedicated reStructuredText Editors

• ReSTedit by Dinu Gherman and Bill Bumgarner
• Rest in Peace
• Enthought Tool Suite editor
• ReText a cross platform program that works like Marked.
• RSTPad a standalone cross-platform editor with live preview

Proprietary editors

Sublime Text

Sublime Text is a completely customizable and extensible source code editor available for Windows, OS X, and Linux. Registration is required for long-term use, but all functions are available in the unregistered version, with occasional reminders to purchase a license. Versions 2 and 3 (currently in beta) support reStructuredText syntax highlighting by default, and several plugins are available through the package manager Package Control to provide snippets and code completion, additional syntax highlighting, conversion to/from RST and other formats, and HTML preview in the browser.

BBEdit / TextWrangler

BBEdit (and its free variant TextWrangler) for Mac can syntax-highlight reStructuredText using this codeless language module.

TextMate

TextMate, a proprietary general-purpose GUI text editor for Mac OS X, has a bundle for reStructuredText.

Intype

Intype is a proprietary text editor for Windows, that support reStructuredText out of the box.

E Text Editor

E is a proprietary Text Editor licensed under the "Open Company License". It supports TextMate's bundles, so it should support reStructuredText the same way TextMate does.

PyCharm

PyCharm (and other IntelliJ platform IDEs?) has ReST/Sphinx support (syntax highlighting, autocomplete and preview).)

Wiki

here are some Wiki programs that support the reStructuredText markup as the native markup syntax, or as an add-on:

MediaWiki

MediaWiki reStructuredText extension allows for reStructuredText markup in MediaWiki surrounded by <rst> and </rst>.

rstiki

rstiki is a minimalist single-file personal wiki using reStructuredText syntax (via docutils) inspired by pwyky. It does not support authorship indication, versioning, hierarchy, chrome/framing/templating or styling. It leverages docutils/reStructuredText as the wiki syntax. As such, it's under 200 lines of code, and in a single file. You put it in a directory and it runs.

ikiwiki

Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git. There are many other features, including support for blogging, as well as a large array of plugins. It's reStructuredText plugin, however is somewhat limited and is not recommended as its' main markup language at this time.

Ultimately they both produce the same HTML but Html.TextBoxFor() is strongly typed where as Html.TextBox isn't.

1:  @Html.TextBox("Name")
2:  Html.TextBoxFor(m => m.Name)

will both produce

<input id="Name" name="Name" type="text" />

So what does that mean in terms of use?

Generally two things:

1. The typed TextBoxFor will generate your input names for you. This is usually just the property name but for properties of complex types can include an underscore such as 'customer_name'
2. Using the typed TextBoxFor version will allow you to use compile time checking. So if you change your model then you can check whether there are any errors in your views.

It is generally regarded as better practice to use the strongly typed versions of the HtmlHelpers that were added in MVC2.

You can simply add -Djava.library.path=yourPath to the eclipse.ini.

It means that the version of your default python (python -V) and the version of your default pip (pip -V) do not match. You have built tensorflow with your default python and trying to use a different pip version to install it. In mac, delete /usr/local/bin/pip and rename(copy) pipx.y (whatever x.y version that matches your python version) to pip in that folder.

I solved this using an absolutely positioned div inside the cell (relative).

td {
    position: relative;
}
td > div {
    position: absolute;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    max-width: 100%;        
}

That's it. Then you can either add a top: value to the div or vertically center it:

td > div {      
    top: 0;
    bottom: 0;
    margin: auto 0;
    height: 1.5em; // = line height 
}

To get some space on the right side, you can reduce the max-width a little.

As per the docs, OkHttp version 3 replaced FormEncodingBuilder with FormBody and FormBody.Builder(), so the old examples won't work anymore.

Form and Multipart bodies are now modeled. We've replaced the opaque FormEncodingBuilder with the more powerful FormBody and FormBody.Builder combo.

Similarly we've upgraded MultipartBuilder into MultipartBody, MultipartBody.Part, and MultipartBody.Builder.

So if you're using OkHttp 3.x try the following example:

OkHttpClient client = new OkHttpClient();

RequestBody formBody = new FormBody.Builder()
        .add("message", "Your message")
        .build();
Request request = new Request.Builder()
        .url("http://www.foo.bar/index.php")
        .post(formBody)
        .build();

try {
    Response response = client.newCall(request).execute();

    // Do something with the response.
} catch (IOException e) {
    e.printStackTrace();
}

Here is example code for usage of java's built-in FIFO queue:

public static void main(String[] args) {
    Queue<Integer> myQ = new LinkedList<Integer>();
    myQ.add(1);
    myQ.add(6);
    myQ.add(3);
    System.out.println(myQ);   // 1 6 3
    int first = myQ.poll();    // retrieve and remove the first element
    System.out.println(first); // 1
    System.out.println(myQ);   // 6 3
}

This is a confusion between constructors and instances.

Remember that when you write a component in React:

class Greeter extends React.Component<any, any> {
    render() {
        return <div>Hello, {this.props.whoToGreet}</div>;
    }
}

You use it this way:

return <Greeter whoToGreet='world' />;

You don't use it this way:

let Greet = new Greeter();
return <Greet whoToGreet='world' />;

In the first example, we're passing around Greeter, the constructor function for our component. That's the correct usage. In the second example, we're passing around an instance of Greeter. That's incorrect, and will fail at runtime with an error like "Object is not a function".

The problem with this code

function renderGreeting(Elem: React.Component<any, any>) {
    return <span>Hello, <Elem />!</span>;
}

is that it's expecting an instance of React.Component. What you want is a function that takes a constructor for React.Component:

function renderGreeting(Elem: new() => React.Component<any, any>) {
    return <span>Hello, <Elem />!</span>;
}

or similarly:

function renderGreeting(Elem: typeof React.Component) {
    return <span>Hello, <Elem />!</span>;
}

points is not within the function's scope. You can grab a reference to the variable by using nonlocal:

points = 0
def test():
    nonlocal points
    points += 1

If points inside test() should refer to the outermost (module) scope, use global:

points = 0
def test():
    global points
    points += 1

It may be nicer one to use slice like :

string.slice(1, -1)

You can use String.Join method to combine items:

var str = String.Join(",", lst);

If there is an interface anywhere in the ThreadProvider hierarchy try putting the name of the Interface as the type of your service provider, eg. if you have say this structure:

public class ThreadProvider implements CustomInterface{
...
}

Then in your controller try this:

@Controller
public class ChiusuraController {

    @Autowired
    private CustomInterface chiusuraProvider;
}

The reason why this is happening is, in your first case when you DID NOT have ChiusuraProvider extend ThreadProvider Spring probably was underlying creating a CGLIB based proxy for you(to handle the @Transaction).

When you DID extend from ThreadProvider assuming that ThreadProvider extends some interface, Spring in that case creates a Java Dynamic Proxy based Proxy, which would appear to be an implementation of that interface instead of being of ChisuraProvider type.

If you absolutely need to use ChisuraProvider you can try AspectJ as an alternative or force CGLIB based proxy in the case with ThreadProvider also this way:

<aop:aspectj-autoproxy proxy-target-class="true"/>

Here is some more reference on this from the Spring Reference site: http://static.springsource.org/spring/docs/3.1.x/spring-framework-reference/html/classic-aop-spring.html#classic-aop-pfb

I use three flags to resolve the problem:

intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
                Intent.FLAG_ACTIVITY_CLEAR_TASK | 
                Intent.FLAG_ACTIVITY_NEW_TASK);

Being a Singleton, you usually do not want it to be destructed.

It will get torn down and deallocated when the program terminates, which is the normal, desired behavior for a singleton. If you want to be able to explicitly clean it, it's fairly easy to add a static method to the class that allows you to restore it to a clean state, and have it reallocate next time it's used, but that's outside of the scope of a "classic" singleton.

In cases where the name attribute is different it is easiest to control the radio group via JQuery. When an option is selected use JQuery to un-select the other options.

My usual way of doing this is:

my %unique = ();
foreach my $item (@myarray)
{
    $unique{$item} ++;
}
my @myuniquearray = keys %unique;

If you use a hash and add the items to the hash. You also have the bonus of knowing how many times each item appears in the list.

grep -n "YOUR SEARCH STRING" * > output-file

The -n will print the line number and the > will redirect grep-results to the output-file.
If you want to "clean" the results you can filter them using pipe | for example:
grep -n "test" * | grep -v "mytest" > output-file will match all the lines that have the string "test" except the lines that match the string "mytest" (that's the switch -v) - and will redirect the result to an output file.
A few good grep-tips can be found on this post

If you just have a Python shell running, type:

import idlelib.PyShell
idlelib.PyShell.main()

double priceG = Double.parseDouble(priceGal.getText().toString());
double valG = Double.parseDouble(volGal.toString());

One of those is throwing the exception. You need to add some logging/printing to see what's in volGal and priceGal - it's not what you think.

You can only send 1 object as a parameter in the body via post. I would change your Post method to

public void Post(ICollection<Product> products)
{
}

and in your angular code you would pass up a product array in JSON notation

Besides the need to have an else, in many cases you will need to use the same condition on multiple locations.

I prefer to extract the condition into a variable:

<c:set var="conditionVar" value="#{expression}"/>

And after that, you can use the condition variable as many times as you need it:

...
<c:if test="#{conditionVar}">
       ...
</c:if>
<c:if test="#{!conditionVar}">
       ...
</c:if>
...
<c:if test="#{conditionVar}">
       ...
</c:if>
<c:if test="#{!conditionVar}">
       ...
</c:if>
...

The c:choose element is good for more complicated situations, but if you need an if else only, I think this approach is better. It is efficient and has the following benefits:

• more readable if the variable name is well chosen
• more reusable because the condition is extracted and the resulting variable can be reused for other ifs and in other expressions. It discourages writing the same condition (and evaluating it) multiple times.

I had a similar problem after I updated eclipse on Mavericks. Eventually I found that in the eclipse plugins directory the com.google.gdt.eclipse.login jar had version numbers at the end. I removed the version number from the name and it all started fine :)

The best way is not to write any initializing statements. This is because if you write int a[]=new int[3] then by default, in Java all the values of array i.e. a[0], a[1] and a[2] are initialized to 0! Regarding the local variable hiding a field, post your entire code for us to come to conclusion.

Compression algorithms almost always have some form of space overhead, which means that they are only effective when compressing data which is sufficiently large that the overhead is smaller than the amount of saved space.

Compressing a string which is only 20 characters long is not too easy, and it is not always possible. If you have repetition, Huffman Coding or simple run-length encoding might be able to compress, but probably not by very much.

Lexeme is basically the unit of a token and it is basically sequence of characters that matches the token and helps to break the source code into tokens.

For example: If the source is x=b, then the lexemes would be x, =, b and the tokens would be <id, 0>, <=>, <id, 1>.

I would consider right method from StringUtils class from Apache Commons Lang: http://commons.apache.org/proper/commons-lang/apidocs/org/apache/commons/lang3/StringUtils.html#right(java.lang.String,%20int)

It is safe. You will not get NullPointerException or StringIndexOutOfBoundsException.

Example usage:

StringUtils.right("abcdef", 3)

You can find more examples under the above link.

Conversion from signed to unsigned does not necessarily just copy or reinterpret the representation of the signed value. Quoting the C standard (C99 6.3.1.3):

When a value with integer type is converted to another integer type other than _Bool, if the value can be represented by the new type, it is unchanged.

Otherwise, if the new type is unsigned, the value is converted by repeatedly adding or subtracting one more than the maximum value that can be represented in the new type until the value is in the range of the new type.

Otherwise, the new type is signed and the value cannot be represented in it; either the result is implementation-defined or an implementation-defined signal is raised.

For the two's complement representation that's nearly universal these days, the rules do correspond to reinterpreting the bits. But for other representations (sign-and-magnitude or ones' complement), the C implementation must still arrange for the same result, which means that the conversion can't just copy the bits. For example, (unsigned)-1 == UINT_MAX, regardless of the representation.

In general, conversions in C are defined to operate on values, not on representations.

To answer the original question:

unsigned int u = 1234;
int i = -5678;

unsigned int result = u + i;

The value of i is converted to unsigned int, yielding UINT_MAX + 1 - 5678. This value is then added to the unsigned value 1234, yielding UINT_MAX + 1 - 4444.

(Unlike unsigned overflow, signed overflow invokes undefined behavior. Wraparound is common, but is not guaranteed by the C standard -- and compiler optimizations can wreak havoc on code that makes unwarranted assumptions.)

if you want to copy folder from currant directory to binary (build folder) folder

file(COPY ${CMAKE_CURRENT_SOURCE_DIR}/yourFolder/ DESTINATION ${CMAKE_CURRENT_BINARY_DIR}/yourFolder/)

then the syntexe is :

file(COPY pathSource DESTINATION pathDistination)

This simple method solved the problem for me: Copy the content of your dataset, open an empty Excel sheet, choose "Paste Special" -> "Values", and save. Import the new file instead.

(I tried all the existing solutions, and none worked for me. My old dataset appeared to have no missing values, space, special characters, or embedded formulas.)

You cannot put primitive types into collections. However, you can declare them using their corresponding object wrappers and still add the primitive values, as long as the boxing allows you.

Look at the ToLookup and/or ToDictionary extension methods.

You can't.

"The Samsung Emulator has the same functionality as the Generic Android Emulator, but varies with the size and appearance of the device."

The problem with Samsung is that they don't use a generic android image, they have custom apps and they react in custom ways and do weird things you wouldn't expect and when you're trying to fix bugs that's what you want. You cannot get that. You need access to a physical device to get the right ecosystem to hunt down the bugs and map out which intents work and how they work on that device. And sometimes there are errors that only occur on Samsung devices because some of the core rendering code is different as well. I've had errors where all Android devices except Samsung would work flawlessly but the scheme itself could not work on Samsung and had to be scrapped. The only thing Samsung allows is skinning and that won't properly note the changes in the rendering pipeline or how the samsung ecosystem deals with intents.

You can make the device look similar, that's worthless. I don't care what it looks like, I care whether this bug still affects that particular model or whether the tweak to the intents I made rectified the issue and I can't learn that from a pretty picture as the border to the same device.

pointer-events: none;

Is a CSS property that makes events "pass through" the element to which it is applied and makes the event occur on the element "below".

See for details: https://developer.mozilla.org/en-US/docs/Web/CSS/pointer-events

It is not supported up to IE 11; all other vendors support it since quite some time (global support was ~92% in 12/'16): http://caniuse.com/#feat=pointer-events (thanks to @s4y for providing the link in the comments).

If you want to find the folder in a platform independent way, you should query the registry key:

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders\Cache

$http_name_of_the_header_key

i.e if you have origin = domain.com in header, you can use $http_origin to get "domain.com"

In nginx does support arbitrary request header field. In the above example last part of a variable name is the field name converted to lower case with dashes replaced by underscores

Reference doc here: http://nginx.org/en/docs/http/ngx_http_core_module.html#var_http_

For your example the variable would be $http_my_custom_header.

1. Highlight the range in question.
2. On the Home tab, in the Styles Group, Click "Conditional Formatting".
3. Click "Highlight cell rules"

For the first rule,

Click "greater than", then in the value option box, click on the cell criteria you want it to be less than, than use the format drop-down to select your color.

For the second,

Click "less than", then in the value option box, type "=.9*" and then click the cell criteria, then use the formatting just like step 1.

For the third,

Same as the second, except your formula is =".8*" rather than .9.

Here is another example:

##
## Python Properties Example
##
class GetterSetterExample( object ):
    ## Set the default value for x ( we reference it using self.x, set a value using self.x = value )
    __x = None


##
## On Class Initialization - do something... if we want..
##
def __init__( self ):
    ## Set a value to __x through the getter / setter... Since __x is defined above, this doesn't need to be set...
    self.x = 1234

    return None


##
## Define x as a property, ie a getter - All getters should have a default value arg, so I added it - it will not be passed in when setting a value, so you need to set the default here so it will be used..
##
@property
def x( self, _default = None ):
    ## I added an optional default value argument as all getters should have this - set it to the default value you want to return...
    _value = ( self.__x, _default )[ self.__x == None ]

    ## Debugging - so you can see the order the calls are made...
    print( '[ Test Class ] Get x = ' + str( _value ) )

    ## Return the value - we are a getter afterall...
    return _value


##
## Define the setter function for x...
##
@x.setter
def x( self, _value = None ):
    ## Debugging - so you can see the order the calls are made...
    print( '[ Test Class ] Set x = ' + str( _value ) )

    ## This is to show the setter function works.... If the value is above 0, set it to a negative value... otherwise keep it as is ( 0 is the only non-negative number, it can't be negative or positive anyway )
    if ( _value > 0 ):
        self.__x = -_value
    else:
        self.__x = _value


##
## Define the deleter function for x...
##
@x.deleter
def x( self ):
    ## Unload the assignment / data for x
    if ( self.__x != None ):
        del self.__x


##
## To String / Output Function for the class - this will show the property value for each property we add...
##
def __str__( self ):
    ## Output the x property data...
    print( '[ x ] ' + str( self.x ) )


    ## Return a new line - technically we should return a string so it can be printed where we want it, instead of printed early if _data = str( C( ) ) is used....
    return '\n'

##
##
##
_test = GetterSetterExample( )
print( _test )

## For some reason the deleter isn't being called...
del _test.x

Basically, the same as the C( object ) example except I'm using x instead... I also don't initialize in __init - ... well.. I do, but it can be removed because __x is defined as part of the class....

The output is:

[ Test Class ] Set x = 1234
[ Test Class ] Get x = -1234
[ x ] -1234

and if I comment out the self.x = 1234 in init then the output is:

[ Test Class ] Get x = None
[ x ] None

and if I set the _default = None to _default = 0 in the getter function ( as all getters should have a default value but it isn't passed in by the property values from what I've seen so you can define it here, and it actually isn't bad because you can define the default once and use it everywhere ) ie: def x( self, _default = 0 ):

[ Test Class ] Get x = 0
[ x ] 0

Note: The getter logic is there just to have the value be manipulated by it to ensure it is manipulated by it - the same for the print statements...

Note: I'm used to Lua and being able to dynamically create 10+ helpers when I call a single function and I made something similar for Python without using properties and it works to a degree, but, even though the functions are being created before being used, there are still issues at times with them being called prior to being created which is strange as it isn't coded that way... I prefer the flexibility of Lua meta-tables and the fact I can use actual setters / getters instead of essentially directly accessing a variable... I do like how quickly some things can be built with Python though - for instance gui programs. although one I am designing may not be possible without a lot of additional libraries - if I code it in AutoHotkey I can directly access the dll calls I need, and the same can be done in Java, C#, C++, and more - maybe I haven't found the right thing yet but for that project I may switch from Python..

Note: The code output in this forum is broken - I had to add spaces to the first part of the code for it to work - when copy / pasting ensure you convert all spaces to tabs.... I use tabs for Python because in a file which is 10,000 lines the filesize can be 512KB to 1MB with spaces and 100 to 200KB with tabs which equates to a massive difference for file size, and reduction in processing time...

Tabs can also be adjusted per user - so if you prefer 2 spaces width, 4, 8 or whatever you can do it meaning it is thoughtful for developers with eye-sight deficits.

Note: All of the functions defined in the class aren't indented properly because of a bug in the forum software - ensure you indent it if you copy / paste

Using parameter --force:

npm i -f

The following works as of now (tested in chrome and firefox):

<form onsubmit="event.preventDefault(); return validateMyForm();">

where validateMyForm() is a function that returns false if validation fails. The key point is to use the name event. We cannot use for e.g. e.preventDefault()

To print a schema, I use jade and do an export to a file of the database then bring it into word to format and print

• "r" is the same as "rt" for Translated mode
• "rb" is non-translated mode.

This makes a difference on Windows, at least. See that link for details.

You are off slightly on a few things here, so hopefully the following helps.

Firstly, you don't need to select ranges to access their properties, you can just specify their address etc. Secondly, unless you are manipulating the values within the range, you don't actually need to set them to a variant. If you do want to manipulate the values, you can leave out the bounds of the array as it will be set when you define the range.

It's also good practice to use Option Explicit at the top of your modules to force variable declaration.

The following will do what you are after:

Sub ARRAYER()
    Dim Number_of_Sims As Integer, i As Integer

    Number_of_Sims = 10

    For i = 1 To Number_of_Sims
       'Do your calculation here to update C4 to G4
       Range(Cells(4 + i, "C"), Cells(4 + i, "G")).Value = Range("C4:G4").Value
    Next
End Sub

If you do want to manipulate the values within the array then do this:

Sub ARRAYER()
    Dim Number_of_Sims As Integer, i As Integer
    Dim anARRAY as Variant

    Number_of_Sims = 10

    For i = 1 To Number_of_Sims
       'Do your calculation here to update C4 to G4
       anARRAY= Range("C4:G4").Value

       'You can loop through the array and manipulate it here

       Range(Cells(4 + i, "C"), Cells(4 + i, "G")).Value = anARRAY
    Next
End Sub

The easiest method is to use the toArray(IntFunction<A[]> generator) method with an array constructor reference. This is suggested in the API documentation for the method.

String[] stringArray = stringStream.toArray(String[]::new);

What it does is find a method that takes in an integer (the size) as argument, and returns a String[], which is exactly what (one of the overloads of) new String[] does.

You could also write your own IntFunction:

Stream<String> stringStream = ...;
String[] stringArray = stringStream.toArray(size -> new String[size]);

The purpose of the IntFunction<A[]> generator is to convert an integer, the size of the array, to a new array.

Example code:

Stream<String> stringStream = Stream.of("a", "b", "c");
String[] stringArray = stringStream.toArray(size -> new String[size]);
Arrays.stream(stringArray).forEach(System.out::println);

Prints:

a
b
c

To disable CSRF for class based views the following worked for me.
Using django 1.10 and python 3.5.2

from django.views.decorators.csrf import csrf_exempt
from django.utils.decorators import method_decorator

@method_decorator(csrf_exempt, name='dispatch')
class TestView(View):
    def post(self, request, *args, **kwargs):
        return HttpResponse('Hello world')

As indicated by the other answers, the error is to due to k = list[0:j], where your key is converted to a list. One thing you could try is reworking your code to take advantage of the split function:

# Using with ensures that the file is properly closed when you're done
with open('filename.txt', 'rb') as f:
  d = {}
  # Here we use readlines() to split the file into a list where each element is a line
  for line in f.readlines():
    # Now we split the file on `x`, since the part before the x will be
    # the key and the part after the value
    line = line.split('x')
    # Take the line parts and strip out the spaces, assigning them to the variables
    # Once you get a bit more comfortable, this works as well:
    # key, value = [x.strip() for x in line] 
    key = line[0].strip()
    value = line[1].strip()
    # Now we check if the dictionary contains the key; if so, append the new value,
    # and if not, make a new list that contains the current value
    # (For future reference, this is a great place for a defaultdict :)
    if key in d:
      d[key].append(value)
    else:
      d[key] = [value]

print d
# {'AAA': ['111', '112'], 'AAC': ['123'], 'AAB': ['111']}

Note that if you are using Python 3.x, you'll have to make a minor adjustment to get it work properly. If you open the file with rb, you'll need to use line = line.split(b'x') (which makes sure you are splitting the byte with the proper type of string). You can also open the file using with open('filename.txt', 'rU') as f: (or even with open('filename.txt', 'r') as f:) and it should work fine.

You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.

Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.

You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.

The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.

You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.

Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.

But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).

You should provide @2x images for the Retina Macbook Pro and future Retina Macs.

foreach (DataGridViewColumn c in dataGridView.Columns)
    c.Width = c.GetPreferredWidth(DataGridViewAutoSizeColumnMode.AllCells, true);

This should work whether the dataGridView has been displayed or not (i.e. even if called from the class constructor).

The same method, but with DataGridViewAutoSizeColumnMode.DisplayedCells, fails in the above case for the obvious reason - no cell has been displayed yet! For some non-obvious reason, AutoResizeColumns also fails in this case.

Check the service name of a database by

sql> show parameter service;

To supplement what everyone else has said above, your js file is being read on the client side when you have a path to it in your HTML file. At least that was the problem for me. I had it as a script in my tag in my index.html Hope this helps!

Arrays.sort(yourArray)

will do the job perfectly

It's used for proxying requests to other servers.

An example from http://wiki.nginx.org/LoadBalanceExample is:

http {
  upstream myproject {
    server 127.0.0.1:8000 weight=3;
    server 127.0.0.1:8001;
    server 127.0.0.1:8002;    
    server 127.0.0.1:8003;
  }

  server {
    listen 80;
    server_name www.domain.com;
    location / {
      proxy_pass http://myproject;
    }
  }
}

This means all requests for / go to the any of the servers listed under upstream XXX, with a preference for port 8000.

When you put the username and password in front of the host, this data is not sent that way to the server. It is instead transformed to a request header depending on the authentication schema used. Most of the time this is going to be Basic Auth which I describe below. A similar (but significantly less often used) authentication scheme is Digest Auth which nowadays provides comparable security features.

With Basic Auth, the HTTP request from the question will look something like this:

GET / HTTP/1.1
Host: example.com
Authorization: Basic Zm9vOnBhc3N3b3Jk

The hash like string you see there is created by the browser like this: base64_encode(username + ":" + password).

To outsiders of the HTTPS transfer, this information is hidden (as everything else on the HTTP level). You should take care of logging on the client and all intermediate servers though. The username will normally be shown in server logs, but the password won't. This is not guaranteed though. When you call that URL on the client with e.g. curl, the username and password will be clearly visible on the process list and might turn up in the bash history file.

When you send passwords in a GET request as e.g. http://example.com/login.php?username=me&password=secure the username and password will always turn up in server logs of your webserver, application server, caches, ... unless you specifically configure your servers to not log it. This only applies to servers being able to read the unencrypted http data, like your application server or any middleboxes such as loadbalancers, CDNs, proxies, etc. though.

Basic auth is standardized and implemented by browsers by showing this little username/password popup you might have seen already. When you put the username/password into an HTML form sent via GET or POST, you have to implement all the login/logout logic yourself (which might be an advantage and allows you to more control over the login/logout flow for the added "cost" of having to implement this securely again). But you should never transfer usernames and passwords by GET parameters. If you have to, use POST instead. The prevents the logging of this data by default.

When implementing an authentication mechanism with a user/password entry form and a subsequent cookie-based session as it is commonly used today, you have to make sure that the password is either transported with POST requests or one of the standardized authentication schemes above only.

Concluding I could say, that transfering data that way over HTTPS is likely safe, as long as you take care that the password does not turn up in unexpected places. But that advice applies to every transfer of any password in any way.

According to the Microsoft documentation, the TimeSpan structure exposes Hours, Minutes, Seconds, and Milliseconds as integer members. Maybe you want something like:

dateDifference.Hours.ToString() + " hrs, " + dateDifference.Minutes.ToString() + " mins, " + dateDifference.Seconds.ToString() + " secs"

There are numerous methods of accomplishing this, which I'll detail with a few examples below.

Pure CSS (using only one colored image)

You can find an article related to this technique here.

Pure CSS (using a grayscale and colored images)

This approach requires two copies of an image: one in grayscale and the other in full color. Using the CSS :hover psuedoselector, you can update the background of your element to toggle between the two:

#yourimage { 
    background: url(../grayscale-image.png);
}
#yourImage:hover { 
    background: url(../color-image.png};
}

#google {_x000D_
  background: url('http://www.google.com/logos/keystroke10-hp.png');_x000D_
  height: 95px;_x000D_
  width: 275px;_x000D_
  display: block;_x000D_
  /* Optional for a gradual animation effect */_x000D_
  transition: 0.5s;_x000D_
}_x000D_
_x000D_
#google:hover {_x000D_
  background: url('https://graphics217b.files.wordpress.com/2011/02/logo1w.png');_x000D_
}

<a id='google' href='http://www.google.com'></a>

This could also be accomplished by using a Javascript-based hover effect such as jQuery's hover() function in the same manner.

Consider a Third-Party Library

The desaturate library is a common library that allows you to easily switch between a grayscale version and full-colored version of a given element or image.

ORA-12560: TNS:erro de adaptador de protocolo

1. set Environment Variables: ORACLE_BASE, ORACLE_HOME, ORACLE_SID
2. make sure your user is part of ORACLE_GROUP_NAME (Windows)
3. make sure the file ORACLE_HOME/network/admin/sqlnet.ora is: SQLNET.AUTHENTICATION_SERVICES = (NTS)
4. (Windows) Be carefull when you add a new Oracle client: adding a new path to the PATH env. variable can mess things up. The first entry in this variable makes a difference: certify that the sqlplus executable in the ORACLE_HOME (ORACLE_HOME/bin) comes first in the PATH env. variable.

This is the simplest way I found after using reflector. I created an extension method for that:

public static class ProcessExtensions
{
    public static bool IsRunning(this Process process)
    {
        if (process == null) 
            throw new ArgumentNullException("process");

        try
        {
            Process.GetProcessById(process.Id);
        }
        catch (ArgumentException)
        {
            return false;
        }
        return true;
    }
}

The Process.GetProcessById(processId) method calls the ProcessManager.IsProcessRunning(processId) method and throws ArgumentException in case the process does not exist. For some reason the ProcessManager class is internal...

You do not have permissions to access the file. Please be sure whether you can access the file in that drive.

string route= @"E:\Sample.text";
FileStream fs = new FileStream(route, FileMode.Create);

You have to provide the file name to create. Please try this, now you can create.

Prints:

python test.py

If you are using Kotlin, you might as well keep your code as succinct as possible. The run method turns the receiver into this and returns the value of the block. this as HttpURLConnection creates a smart cast. bufferedReader().readText() avoids a bunch of boilerplate code.

return URL(url).run {
        openConnection().run {
            this as HttpURLConnection
            inputStream.bufferedReader().readText()
        }
}

You can also wrap this into an extension function.

fun URL.getText(): String {
    return openConnection().run {
                this as HttpURLConnection
                inputStream.bufferedReader().readText()
            }
}

And call it like this

return URL(url).getText()

Finally, if you are super lazy, you can extend the String class instead.

fun String.getUrlText(): String {
    return URL(this).run {
            openConnection().run {
                this as HttpURLConnection
                inputStream.bufferedReader().readText()
            }
    }
}

And call it like this

return "http://somewhere.com".getUrlText()

Just because you're in PowerShell don't forgot about good ol' exes. Sometimes they can provide the easiest solution e.g.:

icacls.exe $folder /grant 'domain\user:(OI)(CI)(M)'

You could call an mWebView.reload(); That's what it does

Here, I'll over-architect the answer using LINQ. Just shows that there's more than 'n' ways to cook an egg:

public int countTrue(string data)
{
    string[] splitdata = data.Split(',');

    var results = from p in splitdata
            where p.Contains("true")
            select p;

    return results.Count();
}

I have used this library with sucess

http://plugins.krajee.com/checkbox-x

It requires jQuery and bootstrap 3.x

Download the zip here: https://github.com/kartik-v/bootstrap-checkbox-x/zipball/master

Put the contents of the zip in a folder within your project

Pop the needed libs in your header

<link href="http://netdna.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">
<link href="path/to/css/checkbox-x.min.css" media="all" rel="stylesheet" type="text/css" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.12.3/jquery.min.js"></script>
<script src="path/to/js/checkbox-x.min.js" type="text/javascript"></script>

Add the data controls to the element using the data-size="xl" to change the size as shown here http://plugins.krajee.com/cbx-sizes-demo

<label for="element_id">CheckME</label>
<input type="checkbox" name="my_element" id="element_id" value="1" data-toggle="checkbox-x" data-three-state="false" data-size="xl"/>

There are numerous other features as well if you browse the plugin site.

The quick answer is 2^16 TCP ports, 64K.

The issues with system imposed limits is a configuration issue, already touched upon in previous comments.

The internal implications to TCP is not so clear (to me). Each port requires memory for it's instantiation, goes onto a list and needs network buffers for data in transit.

Given 64K TCP sessions the overhead for instances of the ports might be an issue on a 32-bit kernel, but not a 64-bit kernel (correction here gladly accepted). The lookup process with 64K sessions can slow things a bit and every packet hits the timer queues, which can also be problematic. Storage for in transit data can theoretically swell to the window size times ports (maybe 8 GByte).

The issue with connection speed (mentioned above) is probably what you are seeing. TCP generally takes time to do things. However, it is not required. A TCP connect, transact and disconnect can be done very efficiently (check to see how the TCP sessions are created and closed).

There are systems that pass tens of gigabits per second, so the packet level scaling should be OK.

There are machines with plenty of physical memory, so that looks OK.

The performance of the system, if carefully configured should be OK.

The server side of things should scale in a similar fashion.

I would be concerned about things like memory bandwidth.

Consider an experiment where you login to the local host 10,000 times. Then type a character. The entire stack through user space would be engaged on each character. The active footprint would likely exceed the data cache size. Running through lots of memory can stress the VM system. The cost of context switches could approach a second!

This is discussed in a variety of other threads: https://serverfault.com/questions/69524/im-designing-a-system-to-handle-10000-tcp-connections-per-second-what-problems

Another solution is you could use a background image to mimic the look of a left border

1. Create the border-left style you require as a graphic
2. Position it to the very left of your div (make it long enough to handle roughly two text size increases for older browsers)
3. Set the vertical position 50% from the top of your div.

You might need to tweak for IE (as per usual) but it's worth a shot if that's the design you are going for.

• I am generally against using images for something that CSS inherently provides, but sometimes if the design needs it, there's no other way round it.

Lots of answers already exist here! I am answering this question with additional and reliable solutions:

Using PowerManager.WakeLock is not so reliable a solution, as the app requires additional permissions.

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

Also, if it accidentally remains holding the wake lock, it can leave the screen on.

So, I recommend not using the PowerManager.WakeLock solution. Instead of this, use any of the following solutions:

First:

We can use getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON); in onCreate()

@Override
        protected void onCreate(Bundle icicle) {
            super.onCreate(icicle);    
            getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
        }

Second:

we can use keepScreenOn

1. implementation using setKeepScreenOn() in java code:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        View v = getLayoutInflater().inflate(R.layout.driver_home, null);// or any View (incase generated programmatically ) 
        v.setKeepScreenOn(true);
        setContentView(v);
       }

Docs http://developer.android.com/reference/android/view/View.html#setKeepScreenOn(boolean)

2. Adding keepScreenOn to xml layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:keepScreenOn="true" >

Docs http://developer.android.com/reference/android/view/View.html#attr_android%3akeepScreenOn

Notes (some useful points):

1. It doesn't matter that keepScreenOn should be used on a Main/Root/Parent View. It can be used with any child view and will work the same way it works in a parent view.
2. The only thing that matters is that the view's visibility must be visible. Otherwise, it will not work!

Another working example, using similar approach posted : create a html form, use javascript to simulate the post. This does 2 things : post data to a new page and open it in a new window/tab.

HTML

<form name='myForm' target="_blank" action='newpage.html' method='post'>
<input type="hidden" name="thisIsTheParameterName" value="testDataToBePosted"/>
</form>

JavaScript

document.forms["myForm"].submit();

put .; at classpath value in beginning..it will start working...it happens because it searches the class file in classpath which is mentioned in path variable.

First copy the source range then paste-special on target range with Transpose:=True, short sample:

Option Explicit

Sub test()
  Dim sourceRange As Range
  Dim targetRange As Range

  Set sourceRange = ActiveSheet.Range(Cells(1, 1), Cells(5, 1))
  Set targetRange = ActiveSheet.Cells(6, 1)

  sourceRange.Copy
  targetRange.PasteSpecial Paste:=xlPasteValues, Operation:=xlNone, SkipBlanks:=False, Transpose:=True
End Sub

The Transpose function takes parameter of type Varaiant and returns Variant.

  Sub transposeTest()
    Dim transposedVariant As Variant
    Dim sourceRowRange As Range
    Dim sourceRowRangeVariant As Variant

    Set sourceRowRange = Range("A1:H1") ' one row, eight columns
    sourceRowRangeVariant = sourceRowRange.Value
    transposedVariant = Application.Transpose(sourceRowRangeVariant)

    Dim rangeFilledWithTransposedData As Range
    Set rangeFilledWithTransposedData = Range("I1:I8") ' eight rows, one column
    rangeFilledWithTransposedData.Value = transposedVariant
  End Sub

I will try to explaine the purpose of 'calling transpose twice'. If u have row data in Excel e.g. "a1:h1" then the Range("a1:h1").Value is a 2D Variant-Array with dimmensions 1 to 1, 1 to 8. When u call Transpose(Range("a1:h1").Value) then u get transposed 2D Variant Array with dimensions 1 to 8, 1 to 1. And if u call Transpose(Transpose(Range("a1:h1").Value)) u get 1D Variant Array with dimension 1 to 8.

First Transpose changes row to column and second transpose changes the column back to row but with just one dimension.

If the source range would have more rows (columns) e.g. "a1:h3" then Transpose function just changes the dimensions like this: 1 to 3, 1 to 8 Transposes to 1 to 8, 1 to 3 and vice versa.

Hope i did not confuse u, my english is bad, sorry :-).

If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").

Date and Time format explanation

aa : ( AM / PM )

You've got a workable idea, but the #flatten! is in the wrong place -- it flattens its receiver, so you could use it to turn [1, 2, ['foo', 'bar']] into [1,2,'foo','bar'].

I'm doubtless forgetting some approaches, but you can concatenate:

a1.concat a2
a1 + a2              # creates a new array, as does a1 += a2

or prepend/append:

a1.push(*a2)         # note the asterisk
a2.unshift(*a1)      # note the asterisk, and that a2 is the receiver

or splice:

a1[a1.length, 0] = a2
a1[a1.length..0] = a2
a1.insert(a1.length, *a2)

or append and flatten:

(a1 << a2).flatten!  # a call to #flatten instead would return a new array

Ok, finally found the solution.

Probably due to lack of experience with ReactJS and web development...

    var Task = React.createClass({
    render: function() {
      var percentage = this.props.children + '%';
      ....
        <div className="ui-progressbar-value ui-widget-header ui-corner-left" style={{width : percentage}}/>
      ...

I created the percentage variable outside in the render function.

Assume that you've defined do_something as a function, and you'd like to perform it N times. Maybe you can try the following:

todos = [do_something] * N  
for doit in todos:  
    doit()

Based on the List Members Instance docs, the easiest way is to use a PUT request which according to the docs either "adds a new list member or updates the member if the email already exists on the list".

Furthermore apikey is definitely not part of the json schema and there's no point in including it in your json request.

Also, as noted in @TooMuchPete's comment, you can use CURLOPT_USERPWD for basic http auth as illustrated in below.

I'm using the following function to add and update list members. You may need to include a slightly different set of merge_fields depending on your list parameters.

$data = [
    'email'     => '[email protected]',
    'status'    => 'subscribed',
    'firstname' => 'john',
    'lastname'  => 'doe'
];

syncMailchimp($data);

function syncMailchimp($data) {
    $apiKey = 'your api key';
    $listId = 'your list id';

    $memberId = md5(strtolower($data['email']));
    $dataCenter = substr($apiKey,strpos($apiKey,'-')+1);
    $url = 'https://' . $dataCenter . '.api.mailchimp.com/3.0/lists/' . $listId . '/members/' . $memberId;

    $json = json_encode([
        'email_address' => $data['email'],
        'status'        => $data['status'], // "subscribed","unsubscribed","cleaned","pending"
        'merge_fields'  => [
            'FNAME'     => $data['firstname'],
            'LNAME'     => $data['lastname']
        ]
    ]);

    $ch = curl_init($url);

    curl_setopt($ch, CURLOPT_USERPWD, 'user:' . $apiKey);
    curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/json']);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'PUT');
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $json);                                                                                                                 

    $result = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

    return $httpCode;
}

if( strtotime($database_date) > strtotime('now') ) {
...

Without dragging ostream into it:

constexpr char const* to_c_str(bool b) {
   return  
    std::array<char const*, 2>{"false", "true "}[b]
   ;
};

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

version: '2'
services:
  ubuntu:
        build: .
        container_name: ubuntu
        volumes:
            - ~/sph/laravel52:/www/laravel
        ports:
          - "80:80"
        tty: true

This is just a warning.

Fixing

This occurs when the default configuration files log4j.properties and log4j.xml can not be found and the application performs no explicit configuration.

To fix that, simply create/copy log4j.properties or log4j.xml into your a location on the classpath (usually the same as the jar files).

Optionally set java option: -Dlog4j.configuration=file:///path/to/log4j.properties.

log4j uses Thread.getContextClassLoader().getResource() to locate the default configuration files and does not directly check the file system. Knowing the appropriate location to place log4j.properties or log4j.xml requires understanding the search strategy of the class loader in use. log4j does not provide a default configuration since output to the console or to the file system may be prohibited in some environments.

Debugging

For debugging, you may try to use -Dlog4j.debug=true parameter.

Configuration of log4j.properties

Sample configuration of log4j.properties:

# Set root logger level to DEBUG and its only appender to A1.
log4j.rootLogger=DEBUG, A1

# A1 is set to be a ConsoleAppender.
log4j.appender.A1=org.apache.log4j.ConsoleAppender

# A1 uses PatternLayout.
log4j.appender.A1.layout=org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern=%-4r [%t] %-5p %c %x - %m%n

# Print only messages of level WARN or above in the package com.foo.
log4j.logger.com.foo=WARN

Here is another configuration file that uses multiple appenders:

log4j.rootLogger=debug, stdout, R

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (%F:%L) - %m%n

log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=example.log

log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1

log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n

Apache Solr

If using Solr, copy <solr>/example/resources/log4j.properties into a location on the classpath.

Sample configuration of log4j.properties from Solr goes like:

#  Logging level
solr.log=logs/
log4j.rootLogger=INFO, file, CONSOLE

log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender

log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=%-4r [%t] %-5p %c %x \u2013 %m%n

#- size rotation with log cleanup.
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.MaxFileSize=4MB
log4j.appender.file.MaxBackupIndex=9

#- File to log to and log format
log4j.appender.file.File=${solr.log}/solr.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%-5p - %d{yyyy-MM-dd HH:mm:ss.SSS}; %C; %m\n

log4j.logger.org.apache.zookeeper=WARN
log4j.logger.org.apache.hadoop=WARN

# set to INFO to enable infostream log messages
log4j.logger.org.apache.solr.update.LoggingInfoStream=OFF

A sting (str-type) in Python is a series of bytes. There is no way of telling just from looking at the string whether this series of bytes represent an ascii string, a string in a 8-bit charset like ISO-8859-1 or a string encoded with UTF-8 or UTF-16 or whatever.

However if you know the encoding used, then you can decode the str into a unicode string and then use a regular expression (or a loop) to check if it contains characters outside of the range you are concerned about.

I went through the Word to PDF pain when someone dumped me with 10000 word files to convert to PDF. Now I did it in C# and used Word interop but it was slow and crashed if I tried to use PC at all.. very frustrating.

This lead me to discovering I could dump interops and their slowness..... for Excel I use (EPPLUS) and then I discovered that you can get a free tool called Spire that allows converting to PDF... with limitations!

You have four choices to supply a password:

1. Set the PGPASSWORD environment variable. For details see the manual:
   http://www.postgresql.org/docs/current/static/libpq-envars.html
2. Use a .pgpass file to store the password. For details see the manual:
   http://www.postgresql.org/docs/current/static/libpq-pgpass.html
3. Use "trust authentication" for that specific user: http://www.postgresql.org/docs/current/static/auth-methods.html#AUTH-TRUST
4. Since PostgreSQL 9.1 you can also use a connection string:
   https://www.postgresql.org/docs/current/static/libpq-connect.html#LIBPQ-CONNSTRING

Set inputType attribute to none in your layout.xml file under EditText

This solution could seem very long, but it's not. I just included many examples so that everything was clear. It worked for me in Mavericks OS.

Note: I combined and edited some of the answers shown above, added some examples and format and posted the result, so the credit goes mostly to the creators of the original posts.

1. Download Maven from here.

2. Open the Terminal.

3. Extract the file you just downloaded to the location you want, either manually or by typing the following lines in the Terminal (fill the required data):

   mv [Your file name] [Destination location]/ tar -xvf [Your file name]

   For example, if our file is named "apache-maven-3.2.1-bin.tar" (Maven version 3.2.1) and we want to locate it in the "/Applications" directory, then we should type the following lines in Terminal:

   mv apache-maven-3.2.1-bin.tar /Applications/
   tar -xvf apache-maven-3.2.1-bin.tar
   

4. If you don't have any JDK (Java Development Kit) installed on your computer, install one.

5. Type "java -version" in Terminal. You should see something like this:

   java version "1.8.0"
   Java(TM) SE Runtime Environment (build 1.8.0-b132)
   Java HotSpot(TM) 64-Bit Server VM (build 25.0-b70, mixed mode)
   

   Remember your java version (in the example, 1.8.0).

6. Type "cd ~/" to go to your home folder.

7. Type "touch .bash_profile".

8. Type "open -e .bash_profile" to open .bash_profile in TextEdit.

9. Type the following in TextEdit (copy everything and replace the required data):

   export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk[Your Java version].jdk/Contents/Home export M2_HOME=[Your file location]/apache-maven-[Your Maven version]/ export PATH=$PATH:$M2_HOME/bin alias mvn='$M2_HOME/bin/mvn'

   For example, in our case we would replace "[Your Java version]" with "1.8.0" (value got in step 5), "[Your file location]" with "/Applications" (value used as "Destination Location" in step 3) and "[Your Maven version]" with "3.2.1" (Maven version observed in step 3), resulting in the following code:

   export JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home
   export M2_HOME=/Applications/apache-maven-3.2.1/
   export PATH=$PATH:$M2_HOME/bin
   alias mvn='$M2_HOME/bin/mvn'
   

10. Save your changes

11. Type "source .bash_profile" to reload .bash_profile and update any functions you add.

12. Type mvn -version. If successful you should see the following:

    Apache Maven [Your Maven version] ([Some weird stuff. Don't worry about this]) Maven home: [Your file location]/apache-maven-[Your Maven version] Java version: [You Java version], vendor: Oracle Corporation Java home: /Library/Java/JavaVirtualMachines/jdk[Your Java version].jdk/Contents/Home/jre [Some other stuff which may vary depending on the configuration and the OS of the computer]

    In our example, the result would be the following:

    Apache Maven 3.2.1 (ea8b2b07643dbb1b84b6d16e1f08391b666bc1e9; 2014-02-14T18:37:52+01:00)
    Maven home: /Applications/apache-maven-3.2.1
    Java version: 1.8.0, vendor: Oracle Corporation
    Java home: /Library/Java/JavaVirtualMachines/jdk1.8.0</b>.jdk/Contents/Home/jre
    Default locale: es_ES, platform encoding: UTF-8
    OS name: "mac os x", version: "10.9.2", arch: "x86_64", family: "mac"
    

IMO, you cannot create an empty Date(java.util). You can create a Date object with null value and can put a null check.

 Date date = new Date(); // Today's date and current time
 Date date2 = new Date(0); // Default date and time
 Date date3 = null; //Date object with null as value.
 if(null != date3) {
    // do your work.
 }

As many others pointed out if you are trying to add a new element at the end of list then something like, array[array.length-1]=x; should do. But this will replace the existing element.

For something like continuous addition to the array. You can keep track of the index and go on adding elements till you reach end and have the function that does the addition return you the next index, which in turn will tell you how many more elements can fit in the array.

Of course in both the cases the size of array will be predefined. Vector can be your other option since you do not want arraylist, which will allow you all the same features and functions and additionally will take care of incrementing the size.

Coming to the part where you want StringBuffer to array. I believe what you are looking for is the getChars(int srcBegin, int srcEnd,char[] dst,int dstBegin) method. Look into it that might solve your doubts. Again I would like to point out that after managing to get an array out of it, you can still only replace the last existing element(character in this case).

I think a really simple answer might be useful here:

return makes the value (a variable, often) available for use by the caller (for example, to be stored by a function that the function using return is within). Without return, your value or variable wouldn't be available for the caller to store/re-use.

print prints to the screen, but does not make the value or variable available for use by the caller.

(Fully admitting that the more thorough answers are more accurate.)

I wasn't able to replicate your bug:

var message = new MailMessage();

message.To.Add("[email protected]");
message.To.Add("[email protected]");

message.From = new MailAddress("[email protected]");
message.Subject = "Test";
message.Body = "Test";

var client = new SmtpClient("localhost", 25);
client.Send(message);

Dumping the contents of the To: MailAddressCollection:

MailAddressCollection (2 items)
DisplayName User Host Address

user example.com [email protected]
user2 example.com [email protected]

And the resulting e-mail as caught by smtp4dev:

Are you sure there's not some other issue going on with your code or SMTP server?

You could write an extension method with linq.

public static bool MyContains(this string str, params string[] p) {
 return !p.Cast<string>().Where(s => !str.Contains(s)).Any();
}

EDIT (thx to sirid):

public static bool MyContains(this string str, params string[] p) {

Yes, the problem is that there are no commits in "bare". This is a problem with the first commit only, if you create the repos in the order (bare,alice). Try doing:

git push --set-upstream origin master

This would only be required the first time. Afterwards it should work normally.

As Chris Johnsen pointed out, you would not have this problem if your push.default was customized. I like upstream/tracking.

To write text to (or read text from) the Windows clipboard use this VBA function:

Function Clipboard$(Optional s$)
    Dim v: v = s  'Cast to variant for 64-bit VBA support
    With CreateObject("htmlfile")
    With .parentWindow.clipboardData
        Select Case True
            Case Len(s): .setData "text", v
            Case Else:   Clipboard = .getData("text")
        End Select
    End With
    End With
End Function

'Three examples of copying text to the clipboard:
Clipboard "Excel Hero was here."
Clipboard var1 & vbLF & var2
Clipboard 123

'To read text from the clipboard:
MsgBox Clipboard

This is a solution that does NOT use MS Forms nor the Win32 API. Instead it uses the Microsoft HTML Object Library which is fast and ubiquitous and NOT deprecated by Microsoft like MS Forms. And this solution respects line feeds. This solution also works from 64-bit Office. Finally, this solution allows both writing to and reading from the Windows clipboard. No other solution on this page has these benefits.

I'd suggest storing these in a Hashtable. You can then access an item in the collection using the key, it's a much more efficient lookup.

var myObjects = new Hashtable();
myObjects.Add(yourObject.Title, yourObject);
...
var myRetrievedObject = myObjects["TargetTitle"];

git reset --soft HEAD^ Will keep the modified changes in your working tree.

git reset --hard HEAD^ WILL THROW AWAY THE CHANGES YOU MADE !!!

The best place to write your JavaScript code is at the end of the document after or right before the </body> tag to load the document first and then execute js code.

<script> ... your code here ... </script>
</body>

And if you write in JQuery the following can be in the head document and it will execute after the document loads:

<script>
$(document).ready(function(){
   //your code here...
});
</script>

You have to enable Type Name Handling and pass that to the (de)serializer as a settings parameter.

Base object1 = new Base() { Name = "Object1" };
Derived object2 = new Derived() { Something = "Some other thing" };
List<Base> inheritanceList = new List<Base>() { object1, object2 };

JsonSerializerSettings settings = new JsonSerializerSettings { TypeNameHandling = TypeNameHandling.All };
string Serialized = JsonConvert.SerializeObject(inheritanceList, settings);
List<Base> deserializedList = JsonConvert.DeserializeObject<List<Base>>(Serialized, settings);

This will result in correct deserialization of derived classes. A drawback to it is that it will name all the objects you are using, as such it will name the list you are putting the objects in.

Consider using django-bulk-update found here on GitHub.

Install: pip install django-bulk-update

Implement: (code taken directly from projects ReadMe file)

from bulk_update.helper import bulk_update

random_names = ['Walter', 'The Dude', 'Donny', 'Jesus']
people = Person.objects.all()

for person in people:
    r = random.randrange(4)
    person.name = random_names[r]

bulk_update(people)  # updates all columns using the default db

Update: As Marc points out in the comments this is not suitable for updating thousands of rows at once. Though it is suitable for smaller batches 10's to 100's. The size of the batch that is right for you depends on your CPU and query complexity. This tool is more like a wheel barrow than a dump truck.

It's unclear if the original problem was the same problem I had: wanting to max CPU threads on computation inside a loop while preserving the iterator's value and keeping inline to avoid passing a ton of variables to a worker function.

for (int i = 0; i < 300; i++)
{
    Task.Run(() => {
        var x = ComputeStuff(datavector, i); // value of i was incorrect
        var y = ComputeMoreStuff(x);
        // ...
    });
}

I got this to work by changing the outer iterator and localizing its value with a gate.

for (int ii = 0; ii < 300; ii++)
{
    System.Threading.CountdownEvent handoff = new System.Threading.CountdownEvent(1);
    Task.Run(() => {
        int i = ii;
        handoff.Signal();

        var x = ComputeStuff(datavector, i);
        var y = ComputeMoreStuff(x);
        // ...

    });
    handoff.Wait();
}

Add a space   between them (or more depending on your preference)

    <div style="text-align: center">         
        <asp:Button ID="btnSubmit" runat="server" Text="Submit" Width="89px" OnClick="btnSubmit_Click" />
        &nbsp;
        <asp:Button ID="btnClear" runat="server" Text="Clear" Width="89px" OnClick="btnClear_Click" />
    </div>

Since Ant 1.8.0 there's apparently also resourceexists

From http://ant.apache.org/manual/Tasks/conditions.html

Tests a resource for existance. since Ant 1.8.0

The actual resource to test is specified as a nested element.

An example:

<resourceexists>
  <file file="${file}"/>
</resourceexists>

I was about rework the example from the above good answer to this question, and then I found this

As of Ant 1.8.0, you may instead use property expansion; a value of true (or on or yes) will enable the item, while false (or off or no) will disable it. Other values are still assumed to be property names and so the item is enabled only if the named property is defined.

Compared to the older style, this gives you additional flexibility, because you can override the condition from the command line or parent scripts:

<target name="-check-use-file" unless="file.exists">
    <available property="file.exists" file="some-file"/>
</target>
<target name="use-file" depends="-check-use-file" if="${file.exists}">
    <!-- do something requiring that file... -->
</target>
<target name="lots-of-stuff" depends="use-file,other-unconditional-stuff"/>

from the ant manual at http://ant.apache.org/manual/properties.html#if+unless

Hopefully this example is of use to some. They're not using resourceexists, but presumably you could?.....

I know this is an old one but it comes up top of Google and all the links provided now seem out of date.

This is the latest list of types Facebook accepts: https://developers.facebook.com/docs/reference/opengraph

If you don't use one of these then the type will default to 'website' which is best used for home pages/summarising a web site.

In answer to the OP you would now want to use a place which will allow you to add lat/long location details.

wmode=opaque or transparent at the beginning of my query string didnt solve anything. This issue for me only occurs on Chrome, and not across even all computers. Just one cpu. It occurs in vimeo embeds as well, and possibly others.

My solution to to attach to the 'shown' and 'hidden' event of the bootstrap modals I am using, add a class which sets the iframe to 1x1 pixels, and remove the class when the modal closes. Seems like it works and is simple to implement.

A data contract is a formal agreement between a service and a client that abstractly describes the data to be exchanged. That is, to communicate, the client and the service do not have to share the same types, only the same data contracts. A data contract precisely defines, for each parameter or return type, what data is serialized (turned into XML) to be exchanged.

Windows Communication Foundation (WCF) uses a serialization engine called the Data Contract Serializer by default to serialize and deserialize data (convert it to and from XML). All .NET Framework primitive types, such as integers and strings, as well as certain types treated as primitives, such as DateTime and XmlElement, can be serialized with no other preparation and are considered as having default data contracts. Many .NET Framework types also have existing data contracts.

What's a "block scheme"?

If I were drawing it, I might draw a box with "for each x in y" written in it.

If you're drawing a flowchart, there's always a loop with a decision box.

Nassi-Schneiderman diagrams have a loop construct you could use.

What ultimately worked for me was the following steps:

1. Configure the Environment Injector Plugin: https://wiki.jenkins-ci.org/display/JENKINS/EnvInject+Plugin
2. Goto to the /job//configure screen
3. In Build Environment section check "Inject environment variables to the build process"
4. In "Properties Content" specified: TZ=America/New_York

if jQuery.fancybox.open is not available (on fancybox 1.3.4) you may need to use semafor to get around the recursion problem:

<a href="/index.html" onclick="return myfunction(this)">click me</a>

<script>

var clickSemafor = false;
myfunction(el)
{
 if (!clickSemafor) {
   clickSemafor = true; 
   return false; // do nothing here when in recursion
 }
 var e = jQuery(el); 
 e.fancybox({
    type: 'iframe',
    href: el.href
  }); 
 e.click();  // you could also use e.trigger('click');
 return false; // prevent default

}
</script>

Try this

 {items && items.title ? items.title : 'No item'}

try this:

var maxid = from i in items
            group i by i.clientid int g
            select new { id = g.Max(i=>i.ID }

Did you want the HTML or text that is inside the li tag?

If so, use either:

$(this).html()

or:

$(this).text()

The val() is for form fields only.

I would recommend getting a mac because the ios simulator is amazing for testing in the early stages of an app. But I do know of a small company we work with that develops using Unity so they don't need a load of macs. That way they only need one mac for the office and that's just to compile the final build. It also means it works on android but it really depends on what your building because it's a games engine. You may want to look into web apps using frameworks like Sencha Touch Mobile

It is possible to hide a button in place without changing its width or removing it from the bar. If you set the style to plain, remove the title, and disable the button, it will disappear. To restore it, just reverse your changes.

-(void)toggleBarButton:(bool)show
{
    if (show) {
        btn.style = UIBarButtonItemStyleBordered;
        btn.enabled = true;
        btn.title = @"MyTitle";
    } else {
        btn.style = UIBarButtonItemStylePlain;
        btn.enabled = false;
        btn.title = nil;
    }
}

Fork

• A copy to your remote repo (cloud) that links it to Joe's
• A copy you can then clone to your local repo and F*%$-up
• When you are done you can push back to your remote
• You can then ask Joe if he wants to use it in his project by clicking pull-request

Clone

• a copy to your local repo (harddrive)

Example:

$number = 4;
print "You have the {$number}th edition book";
//output: "You have the 4th edition book";

Without curly braces PHP would try to find a variable named $numberth, that doesn't exist!

it turns out that with python 2.5.2, del l[:] is slightly slower than l[:] = [] by 1.1 usec.

$ python -mtimeit "l=list(range(1000))" "b=l[:];del b[:]"
10000 loops, best of 3: 29.8 usec per loop
$ python -mtimeit "l=list(range(1000))" "b=l[:];b[:] = []"
10000 loops, best of 3: 28.7 usec per loop
$ python -V

Just wanted to add: If you create a database in mySQL on a live site, then go into PHPMyAdmin and the database isn't showing up - logout of cPanel then log back in, open PHPMyAdmin, and it should be there now.

Android needs to be compiled for every hardware plattform / every device model seperatly with the specific drivers etc. If you manage to do that you need also break the security arrangements every manufacturer implements to prevent the installation of other software - these are also different between each model / manufacturer. So it is possible at in theory, but only there :-)

There is also https://github.com/Valloric/YouCompleteMe and it includes things like Jedi and also has fuzzy match. So far I found YCM to be the fastest among what I have tried.

Based on a Graphviz script I found in an answer to a related question, I've hacked up a ruby script that creates a summary view of a git repository. It elides all linear history and just shows "interesting" commits, i.e. those with multiple parents, multiple children, or pointed to by a branch or tag. Here's a snippet of the graph it generates for jquery:

git-big-picture and BranchMaster are similar tools that try to show only the high-level structure of a graph, by only displaying how tags, branches, merges, etc. are related.

This question has some more options.

You can use ~/img/myImage.png instead of ../img/myImage.png to avoid this error in ASP.NET pages.

@Mihai-Andrei Dinculescu's answer is correct, but for the benefit of searchers, there is also a subtle point that can cause this error.

Adding a '/' on the end of your URL will stop EnableCors from working in all instances (e.g. from the homepage).

I.e. This will not work

var cors = new EnableCorsAttribute("http://testing.azurewebsites.net/", "*", "*");
config.EnableCors(cors);

but this will work:

var cors = new EnableCorsAttribute("http://testing.azurewebsites.net", "*", "*");
config.EnableCors(cors);

The effect is the same if using the EnableCors Attribute.

MySQL casts to Decimal:

Cast bare integer to decimal:

select cast(9 as decimal(4,2));       //prints 9.00

Cast Integers 8/5 to decimal:

select cast(8/5 as decimal(11,4));    //prints 1.6000

Cast string to decimal:

select cast(".885" as decimal(11,3));   //prints 0.885

Cast two int variables into a decimal

mysql> select 5 into @myvar1;
Query OK, 1 row affected (0.00 sec)

mysql> select 8 into @myvar2;
Query OK, 1 row affected (0.00 sec)

mysql> select @myvar1/@myvar2;   //prints 0.6250

Cast decimal back to string:

select cast(1.552 as char(10));   //shows "1.552"

I had this problem on Windows.

My problem was that my %GOPATH% environment variable was set to

C:\Users\john\src\goworkspace

instead of

C:\Users\john\src\goworkspace\

Adding the missing trailing slash at the end fixed it for me.

I don't know why, I did everything exactly the same as Pkosta (https://stackoverflow.com/a/38858040 ) but kept getting error:

I wasted hours on this issue. The culprit? Kotlin.

val playIntent = Intent(Intent.ACTION_VIEW, uri)
intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION)

intent was actually setting getIntent().addFlags instead of operating on my newly declared playIntent.

This is the command to use to tell Gradle to upgrade the wrapper such that it will grab the distribution versions of libraries that includes source code:

./gradlew wrapper --gradle-version <version> --distribution-type all

Specifying the distribution-type with "all" will make sure Gradle downloads source files for use by your development environment.

Pros:

• IDEs will have immediate access to source code. For example, Intellij IDEA won't prompt you to update your build scripts to include the source distro (because this command already did that)

Cons:

• Longer/Bigger build process because it's downloading source code. This is a waste of time/space on a build or CI server where the source code is not necessary.

Please comment or provide another answer if you know of any command line option to tell Gradle not to download sources on a build server.

What if you use a character-based BufferedReader instead of byte-based InputStream?

BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
String line = reader.readLine();
while (line != null) { 
    ...
    line = reader.readLine();
}

Don't forget that readLine() skips the new-lines!

I found that the hostname was not visible to other containers when using docker run. This turns out to be a known issue (perhaps more a known feature), with part of the discussion being:

We should probably add a warning to the docs about using hostname. I think it is rarely useful.

The correct way of assigning a hostname - in terms of container networking - is to define an alias like so:

services:
  some-service:
    networks:
      some-network:
        aliases:
          - alias1
          - alias2

Unfortunately this still doesn't work with docker run. The workaround is to assign the container a name:

docker-compose run --name alias1 some-service

And alias1 can then be pinged from the other containers.

UPDATE: As @grilix points out, you should use docker-compose run --use-aliases to make the defined aliases available.

The best methods are already given but why not look at a couple of other methods for fun? Warning: these are more expensive methods but do serve in other circumstances.

The expensive regex method and the css attribute selector with starts with ^ operator

Option Explicit

Public Sub test()

    Debug.Print StartWithSubString("ab", "abc,d")

End Sub

Regex:

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft VBScript Regular Expressions
    Dim re As VBScript_RegExp_55.RegExp
    Set re = New VBScript_RegExp_55.RegExp

    re.Pattern = "^" & substring

    StartWithSubString = re.test(testString)

End Function

Css attribute selector with starts with operator

Public Function StartWithSubString(ByVal substring As String, ByVal testString As String) As Boolean
    'required reference Microsoft HTML Object Library
    Dim html As MSHTML.HTMLDocument
    Set html = New MSHTML.HTMLDocument

    html.body.innerHTML = "<div test=""" & testString & """></div>"

    StartWithSubString = html.querySelectorAll("[test^=" & substring & "]").Length > 0

End Function

You can also use:

@Scripts.RenderFormat("<script type=\"text/javascript\" src=\"{0}\"></script>", "~/bundles/mybundle")

To specify the format of your output in a scenario where you need to use Charset, Type, etc.

If your lines are multiple points instead, you can use this version.

Using TempData

Represents a set of data that persists only from one request to the next

[HttpPost]
public ActionResult FillStudent(Student student1)
{
    TempData["student"]= new Student();
    return RedirectToAction("GetStudent","Student");
}

[HttpGet]
public ActionResult GetStudent(Student passedStd)
{
    Student std=(Student)TempData["student"];
    return View();
}

Alternative way Pass the data using Query string

return RedirectToAction("GetStudent","Student", new {Name="John", Class="clsz"});

This will generate a GET Request like Student/GetStudent?Name=John & Class=clsz

Ensure the method you want to redirect to is decorated with [HttpGet] as the above RedirectToAction will issue GET Request with http status code 302 Found (common way of performing url redirect)

I would say, it depends on kind of dev team you are and your application needs.

For example, if you require a lot of querying, that mostly means it would be more work for your developers to use Redis, where your data might be stored in variety of specialized data structures, customized for each type of object for efficiency. In MongoDB the same queries might be easier because the structure is more consistent across your data. On the other hand, in Redis, sheer speed of the response to those queries is the payoff for the extra work of dealing with the variety of structures your data might be stored with.

MongoDB offers simplicity, much shorter learning curve for developers with traditional DB and SQL experience. However, Redis's non-traditional approach requires more effort to learn, but greater flexibility.

Eg. A cache layer can probably be better implemented in Redis. For more schema-able data, MongoDB is better. [Note: both MongoDB and Redis are technically schemaless]

If you ask me, my personal choice is Redis for most requirements.

Lastly, I hope by now you have seen http://antirez.com/post/MongoDB-and-Redis.html

use sep='\s*,\s*' so that you will take care of spaces in column-names:

transactions = pd.read_csv('transactions.csv', sep=r'\s*,\s*',
                           header=0, encoding='ascii', engine='python')

alternatively you can make sure that you don't have unquoted spaces in your CSV file and use your command (unchanged)

prove:

print(transactions.columns.tolist())

Output:

['product_id', 'customer_id', 'store_id', 'promotion_id', 'month_of_year', 'quarter', 'the_year', 'store_sales', 'store_cost', 'unit_sales', 'fact_count']

static arrary meens with giving on elements in side the array

dynamic arrary meens without giving on elements in side the array

example:

     char a[10]; //static array
       char a[];  //dynamic array

Not exactly an answer to the quoting/escaping problem of the original question but probably something that would actually have been more useful for the op:

unset FILES
for f in 2011-*.jpg; do FILES+=("$f"); done
echo "${FILES[@]}"

Where of course the expression would have to be adopted to the specific requirement (e.g. *.jpg for all or 2001-09-11*.jpg for only the pictures of a certain day).

Same issue on macOS and got it fixed by running the same installer again.

Whereas I COULD NOT get it fixed by

1. Changing port
2. Rebooting XAMPP
3. Restarting system

Note: Make sure to select 'XAMPP Core Files' component while running the installer as by default it is not selected.

Though re-running the installer is not smart option when one has to do it every now and then. My installer is xampp-osx-7.0.13-1-installer.dmg

Update: I've got my MAMP working with this simple solution here. So, same should work for XAMPP.

To select data in numerical range you can use BETWEEN which is inclusive.

SELECT JOB FROM MYTABLE WHERE ID BETWEEN 10 AND 15;

You really just need a single struct, and as mentioned in the comments the correct annotations on the field will yield the desired results. JSON is not some extremely variant data format, it is well defined and any piece of json, no matter how complicated and confusing it might be to you can be represented fairly easily and with 100% accuracy both by a schema and in objects in Go and most other OO programming languages. Here's an example;

package main

import (
    "fmt"
    "encoding/json"
)

type Data struct {
    Votes *Votes `json:"votes"`
    Count string `json:"count,omitempty"`
}

type Votes struct {
    OptionA string `json:"option_A"`
}

func main() {
    s := `{ "votes": { "option_A": "3" } }`
    data := &Data{
        Votes: &Votes{},
    }
    err := json.Unmarshal([]byte(s), data)
    fmt.Println(err)
    fmt.Println(data.Votes)
    s2, _ := json.Marshal(data)
    fmt.Println(string(s2))
    data.Count = "2"
    s3, _ := json.Marshal(data)
    fmt.Println(string(s3))
}

https://play.golang.org/p/ScuxESTW5i

Based on your most recent comment you could address that by using an interface{} to represent data besides the count, making the count a string and having the rest of the blob shoved into the interface{} which will accept essentially anything. That being said, Go is a statically typed language with a fairly strict type system and to reiterate, your comments stating 'it can be anything' are not true. JSON cannot be anything. For any piece of JSON there is schema and a single schema can define many many variations of JSON. I advise you take the time to understand the structure of your data rather than hacking something together under the notion that it cannot be defined when it absolutely can and is probably quite easy for someone who knows what they're doing.

Try the following statement:

select  distinct A.[Tag],
     count(A.[Tag]) as TAG_COUNT,
     (SELECT count(*) FROM [TagTbl] AS B WHERE A.[Tag]=B.[Tag] AND B.[ID]>0)
     from [TagTbl] AS A GROUP BY A.[Tag]

The first field will be the tag the second will be the whole count the third will be the positive ones count.

If each user has its own SQL Server login you could try this

select 
    so.name, su.name, so.crdate 
from 
    sysobjects so 
join 
    sysusers su on so.uid = su.uid  
order by 
    so.crdate

For the Platform Independent Users or Windows users, what you can do is:

import runtime:

import (
    "runtime"
    "strings"
)

and then trim the string like this:

if runtime.GOOS == "windows" {
  input = strings.TrimRight(input, "\r\n")
} else {
  input = strings.TrimRight(input, "\n")
}

now you can compare it like that:

if strings.Compare(input, "a") == 0 {
  //....yourCode
}

This is a better approach when you're making use of STDIN on multiple platforms.

Explanation

This happens because on windows lines end with "\r\n" which is known as CRLF, but on UNIX lines end with "\n" which is known as LF and that's why we trim "\n" on unix based operating systems while we trim "\r\n" on windows.

All mentioned solutions until now perform a GroupBy. Even if I only need the first Duplicate all elements of the collections are enumerated at least once.

The following extension function stops enumerating as soon as a duplicate has been found. It continues if a next duplicate is requested.

As always in LINQ there are two versions, one with IEqualityComparer and one without it.

public static IEnumerable<TSource> ExtractDuplicates(this IEnumerable<TSource> source)
{
    return source.ExtractDuplicates(null);
}
public static IEnumerable<TSource> ExtractDuplicates(this IEnumerable<TSource source,
    IEqualityComparer<TSource> comparer);
{
    if (source == null) throw new ArgumentNullException(nameof(source));
    if (comparer == null)
        comparer = EqualityCompare<TSource>.Default;

    HashSet<TSource> foundElements = new HashSet<TSource>(comparer);
    foreach (TSource sourceItem in source)
    {
        if (!foundElements.Contains(sourceItem))
        {   // we've not seen this sourceItem before. Add to the foundElements
            foundElements.Add(sourceItem);
        }
        else
        {   // we've seen this item before. It is a duplicate!
            yield return sourceItem;
        }
    }
}

Usage:

IEnumerable<MyClass> myObjects = ...

// check if has duplicates:
bool hasDuplicates = myObjects.ExtractDuplicates().Any();

// or find the first three duplicates:
IEnumerable<MyClass> first3Duplicates = myObjects.ExtractDuplicates().Take(3)

// or find the first 5 duplicates that have a Name = "MyName"
IEnumerable<MyClass> myNameDuplicates = myObjects.ExtractDuplicates()
    .Where(duplicate => duplicate.Name == "MyName")
    .Take(5);

For all these linq statements the collection is only parsed until the requested items are found. The rest of the sequence is not interpreted.

IMHO that is an efficiency boost to consider.

just to add a detail to what Tamlyn wrote, instead of
$('form').get(0).setAttribute('action', 'baz'); //this works

$('form')[0].setAttribute('action', 'baz');
works equally well

The Bootstrap grid system has four classes:
xs (for phones)
sm (for tablets)
md (for desktops)
lg (for larger desktops)

The classes above can be combined to create more dynamic and flexible layouts.

Tip: Each class scales up, so if you wish to set the same widths for xs and sm, you only need to specify xs.

OK, the answer is easy, but read on:

col-lg- stands for column large = 1200px
col-md- stands for column medium = 992px
col-xs- stands for column extra small = 768px

The pixel numbers are the breakpoints, so for example col-xs is targeting the element when the window is smaller than 768px(likely mobile devices)...

I also created the image below to show how the grid system works, in this examples I use them with 3, like col-lg-6 to show you how the grid system work in the page, look at how lg, md and xs are responsive to the window size:

Open atom editor and then press Alt and menu bar will appear. Now click on View tab and then click on Toggle Menu Bar as seen on this screenshot.

I had the same error and struggled to fix it, then answer above by Nagaraja JB helped me to fix it. In my case:

Was before: JSONObject response_json = new JSONObject(response_data);

Changed it to: JSONArray response_json = new JSONArray(response_data);

This fixed it.

map(float, mylist) should do it.

(In Python 3, map ceases to return a list object, so if you want a new list and not just something to iterate over, you either need list(map(float, mylist) - or use SilentGhost's answer which arguably is more pythonic.)

You could try this:

[DllImport("user32.dll", EntryPoint="FindWindow", SetLastError = true)]
static extern IntPtr FindWindowByCaption(IntPtr ZeroOnly, string lpWindowName);

[DllImport("user32.Dll")]
static extern int PostMessage(IntPtr hWnd, UInt32 msg, int wParam, int lParam);

private const UInt32 WM_CLOSE = 0x0010;

public void ShowAutoClosingMessageBox(string message, string caption)
{
    var timer = new System.Timers.Timer(5000) { AutoReset = false };
    timer.Elapsed += delegate
    {
        IntPtr hWnd = FindWindowByCaption(IntPtr.Zero, caption);
        if (hWnd.ToInt32() != 0) PostMessage(hWnd, WM_CLOSE, 0, 0);
    };
    timer.Enabled = true;
    MessageBox.Show(message, caption);
}

Static methods are treated as global by the JVM, there are not bound to an object instance at all.

It could conceptually be possible if you could call static methods from class objects (like in languages like Smalltalk) but it's not the case in Java.

EDIT

You can overload static method, that's ok. But you can not override a static method, because class are no first-class object. You can use reflection to get the class of an object at run-time, but the object that you get does not parallel the class hierarchy.

class MyClass { ... }
class MySubClass extends MyClass { ... }

MyClass obj1 = new MyClass();
MySubClass obj2 = new MySubClass();

ob2 instanceof MyClass --> true

Class clazz1 = obj1.getClass();
Class clazz2 = obj2.getClass();

clazz2 instanceof clazz1 --> false

You can reflect over the classes, but it stops there. You don't invoke a static method by using clazz1.staticMethod(), but using MyClass.staticMethod(). A static method is not bound to an object and there is hence no notion of this nor super in a static method. A static method is a global function; as a consequence there is also no notion of polymorphism and, therefore, method overriding makes no sense.

But this could be possible if MyClass was an object at run-time on which you invoke a method, as in Smalltalk (or maybe JRuby as one comment suggest, but I know nothing of JRuby).

Oh yeah... one more thing. You can invoke a static method through an object obj1.staticMethod() but that really syntactic sugar for MyClass.staticMethod() and should be avoided. It usually raises a warning in modern IDE. I don't know why they ever allowed this shortcut.

I wrote the following function. It replaces the following:

Single quote ['] with a slash and a single quote [\'].

Backslash [\] with two backslashes [\\]

function escapePhpString($target) {
    $replacements = array(
            "'" => '\\\'',
            "\\" => '\\\\'
    );
    return strtr($target, $replacements);
}

You can modify it to add or remove character replacements in the $replacements array. For example, to replace \r\n, it becomes "\r\n" => "\r\n" and "\n" => "\n".

/**
 * With new line replacements too
 */
function escapePhpString($target) {
    $replacements = array(
            "'" => '\\\'',
            "\\" => '\\\\',
            "\r\n" => "\\r\\n",
            "\n" => "\\n"
    );
    return strtr($target, $replacements);
}

The neat feature about strtr is that it will prefer long replacements.

Example, "Cool\r\nFeature" will escape \r\n rather than escaping \n along.

Building on nickd's answer...

def foo(param1, *param2):
    print(param1)
    print(param2)


def bar(param1, **param2):
    print(param1)
    print(param2)


def three_params(param1, *param2, **param3):
    print(param1)
    print(param2)
    print(param3)


foo(1, 2, 3, 4, 5)
print("\n")
bar(1, a=2, b=3)
print("\n")
three_params(1, 2, 3, 4, s=5)

Output:

1
(2, 3, 4, 5)

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

1
(2, 3, 4)
{'s': 5}

Basically, any number of positional arguments can use *args and any named arguments (or kwargs aka keyword arguments) can use **kwargs.

Taking the hint from #Felipe Oriani, I made the extension which I would like to share here for good.

public static class CollectionExtension
{
    public static void AddUniqueItem<T>(this List<T> list, T item, bool throwException)
    {
        if (!list.Contains(item))
        {
            list.Add(item);
        }
        else if(throwException)
        {
            throw new InvalidOperationException("Item already exists in the list");
        }
    }
    public static bool IsUnique<T>(this List<T> list, IEqualityComparer<T> comparer)
    {
        return list.Count == list.Distinct(comparer).Count();
    }
    public static bool IsUnique<T>(this List<T> list)
    {
        return list.Count == list.Distinct().Count();
    }
}

Just kill all node process and start npm server and run application:

Step1: run command killall -9 node

For windows users, run: taskkill /im node.exe

Run taskkill /f /im node.exe if the process still persists.

Step2: run command npm start --reset-cache

Step3: run command react-native run-ios OR react-native run-android

The .browser call has been removed in jquery 1.9 have a look at http://jquery.com/upgrade-guide/1.9/ for more details.

As stated in the urllib2 documentation:

The urllib2 module has been split across several modules in Python 3 named urllib.request and urllib.error. The 2to3 tool will automatically adapt imports when converting your sources to Python 3.

So you should instead be saying

from urllib.request import urlopen
html = urlopen("http://www.google.com/").read()
print(html)

Your current, now-edited code sample is incorrect because you are saying urllib.urlopen("http://www.google.com/") instead of just urlopen("http://www.google.com/").

This function runs in O(n log(n) + m log(m)) compared to O(n*m) (as seen in the other solutions with loops/indexOf) which can be useful if you are dealing with lots of values.

However, because neither "a" > 1 nor "a" < 1, this only works for elements of the same type.

function intersect_arrays(a, b) {
    var sorted_a = a.concat().sort();
    var sorted_b = b.concat().sort();
    var common = [];
    var a_i = 0;
    var b_i = 0;

    while (a_i < a.length
           && b_i < b.length)
    {
        if (sorted_a[a_i] === sorted_b[b_i]) {
            common.push(sorted_a[a_i]);
            a_i++;
            b_i++;
        }
        else if(sorted_a[a_i] < sorted_b[b_i]) {
            a_i++;
        }
        else {
            b_i++;
        }
    }
    return common;
}

Example:

var array1 = ["cat", "sum", "fun", "hut"], //modified for additional match
    array2 = ["bat", "cat", "dog", "sun", "hut", "gut"];
intersect_arrays(array1, array2);
>> ["cat", "hut"]

The APPLY operator in SQL 2005 and higher works for this:

select
    t.id ,
    t.somedate ,
    t.somevalue ,
    rt.runningTotal
from TestTable t
 cross apply (select sum(somevalue) as runningTotal
                from TestTable
                where somedate <= t.somedate
            ) as rt
order by t.somedate

You can use this script to export or import any database from terminal given at this link: https://github.com/Ridhwanluthra/mysql_import_export_script/blob/master/mysql_import_export_script.sh

echo -e "Welcome to the import/export database utility\n"
echo -e "the default location of mysqldump file is: /opt/lampp/bin/mysqldump\n"
echo -e "the default location of mysql file is: /opt/lampp/bin/mysql\n"
read -p 'Would like you like to change the default location [y/n]: ' location_change
read -p "Please enter your username: " u_name
read -p 'Would you like to import or export a database: [import/export]: ' action
echo

mysqldump_location=/opt/lampp/bin/mysqldump
mysql_location=/opt/lampp/bin/mysql

if [ "$action" == "export" ]; then
    if [ "$location_change" == "y" ]; then
        read -p 'Give the location of mysqldump that you want to use: ' mysqldump_location
        echo
    else
        echo -e "Using default location of mysqldump\n"
    fi
    read -p 'Give the name of database in which you would like to export: ' db_name
    read -p 'Give the complete path of the .sql file in which you would like to export the database: ' sql_file
    $mysqldump_location -u $u_name -p $db_name > $sql_file
elif [ "$action" == "import" ]; then
    if [ "$location_change" == "y" ]; then
        read -p 'Give the location of mysql that you want to use: ' mysql_location
        echo
    else
        echo -e "Using default location of mysql\n"
    fi
    read -p 'Give the complete path of the .sql file you would like to import: ' sql_file
    read -p 'Give the name of database in which to import this file: ' db_name
    $mysql_location -u $u_name -p $db_name < $sql_file
else
    echo "please select a valid command"
fi

You can also use setShowSoftInputOnFocus(boolean) directly on API 21+ or through reflection on API 14+:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    editText.setShowSoftInputOnFocus(false);
} else {
    try {
        final Method method = EditText.class.getMethod(
                "setShowSoftInputOnFocus"
                , new Class[]{boolean.class});
        method.setAccessible(true);
        method.invoke(editText, false);
    } catch (Exception e) {
        // ignore
    }
}

You are dividing by rr which may be 0.0. Check if rr is zero and do something reasonable other than using it in the denominator.

For anyone who is still looking for an answer where the above tricks didn't work. Static linking is the way to solve this problem. Change your Runtime library settings as below

Project properties --> C/C++ --> Code generation --> Runtime Library --> Multi-threaded Debug (/MTd) instead of /MDd

Just select the code and

• on Windows do Ctrl + Alt + L

• on Linux do Ctrl + Windows Key + Alt + L

• on Mac do CMD + Option + L

find()

>>> s = "the dude is a cool dude"
>>> s.find('dude')
4

This helped me for active/inactive routes:

<a routerLink="/user/bob" routerLinkActive #rla="routerLinkActive" [ngClass]="rla.isActive ? 'classIfActive' : 'classIfNotActive'">
</a>

Ref

You can get the count by the below query (without * or any column names).

select from table_name;

Use modern JavaScript!

I'd suggest looking into fetch. It is the ES5 equivalent and uses Promises. It is much more readable and easily customizable.

const url = "http://example.com";
fetch(url, {
    method : "POST",
    body: new FormData(document.getElementById("inputform")),
    // -- or --
    // body : JSON.stringify({
        // user : document.getElementById('user').value,
        // ...
    // })
}).then(
    response => response.text() // .json(), etc.
    // same as function(response) {return response.text();}
).then(
    html => console.log(html)
);

In Node.js, you'll need to import fetch using:

const fetch = require("node-fetch");

If you want to use it synchronously (doesn't work in top scope):

const json = await fetch(url, optionalOptions)
  .then(response => response.json()) // .text(), etc.
  .catch((e) => {});

In C++11 you can. A note beforehand: Don't new the array, there's no need for that.

First, string[] strArray is a syntax error, that should either be string* strArray or string strArray[]. And I assume that it's just for the sake of the example that you don't pass any size parameter.

#include <string>

void foo(std::string* strArray, unsigned size){
  // do stuff...
}

template<class T>
using alias = T;

int main(){
  foo(alias<std::string[]>{"hi", "there"}, 2);
}

Note that it would be better if you didn't need to pass the array size as an extra parameter, and thankfully there is a way: Templates!

template<unsigned N>
void foo(int const (&arr)[N]){
  // ...
}

Note that this will only match stack arrays, like int x[5] = .... Or temporary ones, created by the use of alias above.

int main(){
  foo(alias<int[]>{1, 2, 3});
}

I have gone through this question earlier but did not found complete gui based solution.Today I got a GUI based solution provided by spring.

In short we need to do only that much:

1.Install plugin in eclipse from update site: site link

2.Import project as gradle and browse the .gradle file..that's it.

Complete documentation is here

My suggestion if it is the case that the table is empty or not very very big is to export the create statements as a .sql file, rewrite them as you wish. Also do the same if you have any existing data, i.e. export insert statements (I recommend doing this in a separate file as the create statements). Finally, drop the table and execute first create statement and then inserts.

You can use for that either mysqldump command, included in your MySQL installation or you can also install MySQL Workbench, which is a free graphical tool that includes also this option in a very customisable way without having to look for specific command options.

There are a couple issues here. First, you need to make sure to bind your JSON object back to the model in the controller. This is done by changing

data: JSON.stringify(usersRoles),

to

data: { model: JSON.stringify(usersRoles) },

Secondly, you aren't binding types correctly with your jquery call. If you remove

contentType: "application/json; charset=utf-8",

it will inherently bind back to a string.

All together, use the first ActionResult method and the following jquery ajax call:

    jQuery.ajax({
        type: "POST",
        url: "@Url.Action("AddUser")",
        dataType: "json",
        data: { model: JSON.stringify(usersRoles) },
        success: function (data) { alert(data); },
        failure: function (errMsg) {
        alert(errMsg);
        }
   });

My problem was that I already had some Facebook SDKs in my project (FBSDKLoginKit and FBSDKCoreKit).

I only needed one more SDK (FBSDKShareKit) and imported it, which thus gave "Undefined symbols architecture for arm64".

As the FBSDKShareKit is dependent on an updated version of FBSDKCoreKit, by updating the other frameworks, everything worked again.

There are two main ways that you can do this. One of them is the standard CakePHP way, and the other is using a custom join.

It's worth pointing out that this advice is for CakePHP 2.x, not 3.x.

The CakePHP Way

You would create a relationship with your User model and Messages Model, and use the containable behavior:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array('Message');
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array('User');
}

You need to change the messages.from column to be messages.user_id so that cake can automagically associate the records for you.

Then you can do this from the messages controller:

$this->Message->find('all', array(
    'contain' => array('User')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

The (other) CakePHP way

I recommend using the first method, because it will save you a lot of time and work. The first method also does the groundwork of setting up a relationship which can be used for any number of other find calls and conditions besides the one you need now. However, cakePHP does support a syntax for defining your own joins. It would be done like this, from the MessagesController:

$this->Message->find('all', array(
    'joins' => array(
        array(
            'table' => 'users',
            'alias' => 'UserJoin',
            'type' => 'INNER',
            'conditions' => array(
                'UserJoin.id = Message.from'
            )
        )
    ),
    'conditions' => array(
        'Message.to' => 4
    ),
    'fields' => array('UserJoin.*', 'Message.*'),
    'order' => 'Message.datetime DESC'
));

Note, I've left the field name messages.from the same as your current table in this example.

Using two relationships to the same model

Here is how you can do the first example using two relationships to the same model:

class User extends AppModel {
    public $actsAs = array('Containable');
    public $hasMany = array(
        'MessagesSent' => array(
            'className'  => 'Message',
            'foreignKey' => 'from'
         )
    );
    public $belongsTo = array(
        'MessagesReceived' => array(
            'className'  => 'Message',
            'foreignKey' => 'to'
         )
    );
}

class Message extends AppModel {
    public $actsAs = array('Containable');
    public $belongsTo = array(
        'UserFrom' => array(
            'className'  => 'User',
            'foreignKey' => 'from'
        )
    );
    public $hasMany = array(
        'UserTo' => array(
            'className'  => 'User',
            'foreignKey' => 'to'
        )
    );
}

Now you can do your find call like this:

$this->Message->find('all', array(
    'contain' => array('UserFrom')
    'conditions' => array(
        'Message.to' => 4
    ),
    'order' => 'Message.datetime DESC'
));

Although, I'm pretty sure that as long as there is only one field in the form and one submit button, hitting enter should submit the form, even if there is another form on the page.

You can then capture the form onsubmit with js and do whatever validation or callbacks you want.

Two options for runtime type checking with generics:

Option 1 - Corrupt your constructor

Let's assume you are overriding indexOf(...), and you want to check the type just for performance, to save yourself iterating the entire collection.

Make a filthy constructor like this:

public MyCollection<T>(Class<T> t) {

    this.t = t;
}

Then you can use isAssignableFrom to check the type.

public int indexOf(Object o) {

    if (
        o != null &&

        !t.isAssignableFrom(o.getClass())

    ) return -1;

//...

Each time you instantiate your object you would have to repeat yourself:

new MyCollection<Apples>(Apples.class);

You might decide it isn't worth it. In the implementation of ArrayList.indexOf(...), they do not check that the type matches.

Option 2 - Let it fail

If you need to use an abstract method that requires your unknown type, then all you really want is for the compiler to stop crying about instanceof. If you have a method like this:

protected abstract void abstractMethod(T element);

You can use it like this:

public int indexOf(Object o) {

    try {

        abstractMethod((T) o);

    } catch (ClassCastException e) {

//...

You are casting the object to T (your generic type), just to fool the compiler. Your cast does nothing at runtime, but you will still get a ClassCastException when you try to pass the wrong type of object into your abstract method.

NOTE 1: If you are doing additional unchecked casts in your abstract method, your ClassCastExceptions will get caught here. That could be good or bad, so think it through.

NOTE 2: You get a free null check when you use instanceof. Since you can't use it, you may need to check for null with your bare hands.

Having MATLAB 2014b or newer installed, the MATLAB engine for Python could be used:

import matlab.engine
eng = matlab.engine.start_matlab()
content = eng.load("example.mat", nargout=1)

I faced with the problem like this.

The problem was that I added the public key without '-----BEGIN PUBLIC KEY-----' at the beginning and without '-----END PUBLIC KEY-----'.

So it causes the error.

Initially, my public key was like this:

-----BEGIN PUBLIC KEY-----
WnsbGUXbb0GbJSCwCBAhrzT0s2KMRyqqS7QBiIG7t3H2Qtmde6UoUIcTTPJgv71
......
oNLcaK2wKKyRdcROK7ZTSCSMsJpAFOY
-----END PUBLIC KEY-----

But I used just this part:

WnsbGUXb+b0GbJSCwCBAhrzT0s2KMRyqqS7QBiIG7t3H2Qtmde6UoUIcTTPJgv71
......
oNLcaK2w+KKyRdcROK7ZTSCSMsJpAFOY

As you said GWT does not support reflection. You should use deferred binding instead of reflection, or third party library such as gwt-ent for reflection suppport at gwt layer.

[What you have is just an object, not a "json-object". JSON is a textual notation. What you've quoted is JavaScript code using an array initializer and an object initializer (aka, "object literal syntax").]

If you can rely on having ECMAScript5 features available, you can use the Object.keys function to get an array of the keys (property names) in an object. All modern browsers have Object.keys (including IE9+).

Object.keys(jsonData).forEach(function(key) {
    var value = jsonData[key];
    // ...
});

The rest of this answer was written in 2011. In today's world, A) You don't need to polyfill this unless you need to support IE8 or earlier (!), and B) If you did, you wouldn't do it with a one-off you wrote yourself or grabbed from an SO answer (and probably shouldn't have in 2011, either). You'd use a curated polyfill, possibly from es5-shim or via a transpiler like Babel that can be configured to include polyfills (which may come from es5-shim).

Here's the rest of the answer from 2011:

Note that older browsers won't have it. If not, this is one of the ones you can supply yourself:

if (typeof Object.keys !== "function") {
    (function() {
        var hasOwn = Object.prototype.hasOwnProperty;
        Object.keys = Object_keys;
        function Object_keys(obj) {
            var keys = [], name;
            for (name in obj) {
                if (hasOwn.call(obj, name)) {
                    keys.push(name);
                }
            }
            return keys;
        }
    })();
}

That uses a for..in loop (more info here) to loop through all of the property names the object has, and uses Object.prototype.hasOwnProperty to check that the property is owned directly by the object rather than being inherited.

(I could have done it without the self-executing function, but I prefer my functions to have names, and to be compatible with IE you can't use named function expressions [well, not without great care]. So the self-executing function is there to avoid having the function declaration create a global symbol.)

You shouldn't use the third one because its wrong. "String" takes 7 bytes, not 5.

The first one is a pointer (can be reassigned to a different address), the other two are declared as arrays, and cannot be reassigned to different memory locations (but their content may change, use const to avoid that).

Huh, spent quite a lot of time on a problem with separate DB contexts for each DB schema, hope that it will help somebody else...

I recently started working on a project that had one database with 3 schemas (DB first approach), one of them for user management. There was a DB context scaffolded from each separate schema. Of course, users were related to other schemas as well, eg. schema KB had a table Topic, which had "created by", "last modified by" etc. FK to identity schema, table appuser.

These objects were loaded separately in C#, firstly, topic was loaded from 1 context, then users were loaded via user IDs from the other db context - not nice, have to fix this! (similar to using multiple dbcontexts in the same database with EF 6)

First, I tried to add missing FK instructions from identity schema to KB schema, to EF modelBuilder in KB DB context. The same as if there was only 1 context, but I separated it to 2.

modelBuilder.Entity<Topic>(entity =>
{
  entity.HasOne(d => d.Creator)
    .WithMany(p => p.TopicCreator)
    .HasForeignKey(d => d.CreatorId)
    .HasConstraintName("fk_topic_app_users");

It didnt work, because kb db context didn't have any information about the user object, postgres returned error relation "AppUsers" does not exist. Select statement didnt have proper information about schema, field names etc.

I almost gave up, but then i noticed a switch "-d" when running dotnet ef dbcontext scaffold. Its short for -data-annotations - Use attributes to configure the model (where possible). If omitted, only the fluent API is used. With this switch specified, object properties were defined not in db context OnModelCreating(), but rather on the object itself, with attributes.

This way, EF got sufficient information for generating a proper SQL statement with proper field names and schemas.

TL;DR: separate DB contexts don't handle relations (FKs) between them well, each context only has information about its own entities. When specifying "-data-annotations" switch on dotnet ef dbcontext scaffold, these informations arent stored in each separate context, but on DB objects themselves.

if you want to make use of lamdas and make it a bit easier to read

  List<Map<String,String>> results;

  Comparator<Map<String,String>> sortByName = Comparator.comparing(x -> x.get("Name"));

  public void doSomething(){
    results.sort(sortByName)
  }

map(lambda s: s.strip(), mylist) would be a little better than explicitly looping.
Or for the whole thing at once:

map(lambda s:s.strip(), string.split(','))

That's basically everything you need.

My vote is string.Join

No need for lambda evaluations and temporary functions to be created, fewer function calls, less stack pushing and popping.

One thing bothering me with default parameters is that you can't specify the last parameters but use the default values for the first ones. For example, in your code, you can't create a Foo with no name but a given age (however, if I remember correctly, this will be possible in C++0x, with the unified constructing syntax). Sometimes, this makes sense, but it can also be really awkward.

In my opinion, there is no rule of thumb. Personnaly, I tend to use multiple overloaded constructors (or methods), except if only the last argument needs a default value.
