Programs & Examples On #Docstring

In the end, you only have two options:

You generate your content using Doxygen, or you generate your content using Sphinx*.

1. Doxygen: It is not the tool of choice for most Python projects. But if you have to deal with other related projects written in C or C++ it could make sense. For this you can improve the integration between Doxygen and Python using doxypypy.

2. Sphinx: The defacto tool for documenting a Python project. You have three options here: manual, semi-automatic (stub generation) and fully automatic (Doxygen like).

   1. For manual API documentation you have Sphinx autodoc. This is great to write a user guide with embedded API generated elements.
   2. For semi-automatic you have Sphinx autosummary. You can either setup your build system to call sphinx-autogen or setup your Sphinx with the autosummary_generate config. You will require to setup a page with the autosummaries, and then manually edit the pages. You have options, but my experience with this approach is that it requires way too much configuration, and at the end even after creating new templates, I found bugs and the impossibility to determine exactly what was exposed as public API and what not. My opinion is this tool is good for stub generation that will require manual editing, and nothing more. Is like a shortcut to end up in manual.
   3. Fully automatic. This have been criticized many times and for long we didn't have a good fully automatic Python API generator integrated with Sphinx until AutoAPI came, which is a new kid in the block. This is by far the best for automatic API generation in Python (note: shameless self-promotion).

There are other options to note:

• Breathe: this started as a very good idea, and makes sense when you work with several related project in other languages that use Doxygen. The idea is to use Doxygen XML output and feed it to Sphinx to generate your API. So, you can keep all the goodness of Doxygen and unify the documentation system in Sphinx. Awesome in theory. Now, in practice, the last time I checked the project wasn't ready for production.
• pydoctor*: Very particular. Generates its own output. It has some basic integration with Sphinx, and some nice features.

I think the fix is relative easy without disabling this feature.

def kos_root():
    """Return the pathname of the KOS root directory."""
    global _kos_root
    if _kos_root: return _kos_root

All you need to do is add the triple double quotes string in every function.

Formats

Python docstrings can be written following several formats as the other posts showed. However the default Sphinx docstring format was not mentioned and is based on reStructuredText (reST). You can get some information about the main formats in this blog post.

Note that the reST is recommended by the PEP 287

There follows the main used formats for docstrings.

- Epytext

Historically a javadoc like style was prevalent, so it was taken as a base for Epydoc (with the called Epytext format) to generate documentation.

Example:

"""
This is a javadoc style.

@param param1: this is a first param
@param param2: this is a second param
@return: this is a description of what is returned
@raise keyError: raises an exception
"""

- reST

Nowadays, the probably more prevalent format is the reStructuredText (reST) format that is used by Sphinx to generate documentation. Note: it is used by default in JetBrains PyCharm (type triple quotes after defining a method and hit enter). It is also used by default as output format in Pyment.

Example:

"""
This is a reST style.

:param param1: this is a first param
:param param2: this is a second param
:returns: this is a description of what is returned
:raises keyError: raises an exception
"""

- Google

Google has their own format that is often used. It also can be interpreted by Sphinx (ie. using Napoleon plugin).

Example:

"""
This is an example of Google style.

Args:
    param1: This is the first param.
    param2: This is a second param.

Returns:
    This is a description of what is returned.

Raises:
    KeyError: Raises an exception.
"""

Even more examples

- Numpydoc

Note that Numpy recommend to follow their own numpydoc based on Google format and usable by Sphinx.

"""
My numpydoc description of a kind
of very exhautive numpydoc format docstring.

Parameters
----------
first : array_like
    the 1st param name `first`
second :
    the 2nd param
third : {'value', 'other'}, optional
    the 3rd param, by default 'value'

Returns
-------
string
    a value in a string

Raises
------
KeyError
    when a key error
OtherError
    when an other error
"""

Converting/Generating

It is possible to use a tool like Pyment to automatically generate docstrings to a Python project not yet documented, or to convert existing docstrings (can be mixing several formats) from a format to an other one.

Note: The examples are taken from the Pyment documentation

Use a nice editor like SciTe, select your code, press Ctrl + Q and done.

If you don't have an editor that supports block comments you can use a triple quoted string at the start and the end of your code block to 'effectively' comment it out. It is not the best practice though.

I also experienced that for example:

This code doesnt work and get the intended block error.

class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()

def __unicode__(self):
return self.title

However, when i press tab before typing return self.title statement, the code works.

class Foo(models.Model):
title = models.CharField(max_length=200)
body = models.TextField()
pub_date = models.DateTimeField('date published')
likes = models.IntegerField()

def __unicode__(self):
    return self.title

Hope, this will help others.

I know this post is realy old but now that some time and ant versions passed there is a way to do this with basic ant features and i thought i should share it.

It's done via a recursive macrodef that calls nested tasks (even other macros may be called). The only convention is to use a fixed variable name (element here).

<project name="iteration-test" default="execute" xmlns="antlib:org.apache.tools.ant" xmlns:if="ant:if" xmlns:unless="ant:unless">

    <macrodef name="iterate">
        <attribute name="list" />
        <element name="call" implicit="yes" />
        <sequential>
            <local name="element" />
            <local name="tail" />
            <local name="hasMoreElements" />
            <!-- unless to not get a error on empty lists -->
            <loadresource property="element" unless:blank="@{list}" >
                <concat>@{list}</concat>
                <filterchain>
                    <replaceregex pattern="([^;]*).*" replace="\1" />
                </filterchain>
            </loadresource>
            <!-- call the tasks that handle the element -->
            <call />

            <!-- recursion -->
            <condition property="hasMoreElements">
                <contains string="@{list}" substring=";" />
            </condition>

            <loadresource property="tail" if:true="${hasMoreElements}">
                <concat>@{list}</concat>
                <filterchain>
                    <replaceregex pattern="[^;]*;(.*)" replace="\1" />
                </filterchain>
            </loadresource>

            <iterate list="${tail}" if:true="${hasMoreElements}">
                <call />
            </iterate>
        </sequential>
    </macrodef>

    <target name="execute">
        <fileset id="artifacts.fs" dir="build/lib">
            <include name="*.jar" />
            <include name="*.war" />
        </fileset>

        <pathconvert refid="artifacts.fs" property="artifacts.str" />

        <echo message="$${artifacts.str}: ${artifacts.str}" />
        <!-- unless is required for empty lists to not call the enclosed tasks -->
        <iterate list="${artifacts.str}" unless:blank="${artifacts.str}">
            <echo message="I see:" />
            <echo message="${element}" />
        </iterate>
        <!-- local variable is now empty -->
        <echo message="${element}" />
    </target>
</project>

The key features needed where:

• http://ant.apache.org/manual/ifunless.html introduced in ant 1.9.1 (credits to ant conditional if within a macrodef)
• substrings, many thanks to How to pull out a substring in Ant
• the inline macrodef element.

I didnt manage to make the delimiter variabel, but this may not be a major downside.

No external dependency on 7zip or ZIP - create a vbs script and execute:

    @ECHO Zipping
    mkdir %TEMPDIR%
    xcopy /y /s %FILETOZIP% %TEMPDIR%
    echo Set objArgs = WScript.Arguments > _zipIt.vbs
    echo InputFolder = objArgs(0) >> _zipIt.vbs
    echo ZipFile = objArgs(1) >> _zipIt.vbs
    echo CreateObject("Scripting.FileSystemObject").CreateTextFile(ZipFile, True).Write "PK" ^& Chr(5) ^& Chr(6) ^& String(18, vbNullChar) >> _zipIt.vbs
    echo Set objShell = CreateObject("Shell.Application") >> _zipIt.vbs
    echo Set source = objShell.NameSpace(InputFolder).Items >> _zipIt.vbs
    echo objShell.NameSpace(ZipFile).CopyHere(source) >> _zipIt.vbs
    @ECHO *******************************************
    @ECHO Zipping, please wait..
    echo wScript.Sleep 12000 >> _zipIt.vbs
    CScript  _zipIt.vbs  %TEMPDIR%  %OUTPUTZIP%
    del _zipIt.vbs
    rmdir /s /q  %TEMPDIR%

    @ECHO *******************************************
    @ECHO      ZIP Completed

Open a new terminal and do the followin

M2_HOME=/Users/macbook/apache-maven-3.6.1 //Set where maven is
M2=$M2_HOME/bin                          //Set home as bin
export PATH=$M2:$PATH                   //Place the new path

Then type

mvn -version

You can set this in ./bash_profile to do it automatically each time you run the terminal

Since this only came up hidden in comments, difficult to find as a solution:

You can use java -Dhttps.protocols=TLSv1,TLSv1.1, but you need to use also useSystemProperties()

client = HttpClientBuilder.create().useSystemProperties();

We use this setup in our system now as this enables us to set this only for some usage of the code. In our case we still have some Java 7 running and one API end point disallowed TLSv1, so we use java -Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2 to enable current TLS versions. Thanks @jebeaudet for pointing in this direction.

You don't, basically. A HashMap is fundamentally unordered. Any patterns you might see in the ordering should not be relied on.

There are sorted maps such as TreeMap, but they traditionally sort by key rather than value. It's relatively unusual to sort by value - especially as multiple keys can have the same value.

Can you give more context for what you're trying to do? If you're really only storing numbers (as strings) for the keys, perhaps a SortedSet such as TreeSet would work for you?

Alternatively, you could store two separate collections encapsulated in a single class to update both at the same time?

Strangely enough,

package main

func main () {
    var sessions = map[string] chan int{};
    delete(sessions, "moo");
}

seems to work. This seems a poor use of resources though!

Another way is to check for existence and use the value itself:

package main

func main () {
    var sessions = map[string] chan int{};
    sessions["moo"] = make (chan int);
    _, ok := sessions["moo"];
    if ok {
        delete(sessions, "moo");
    }
}

This is the safer way:

var elements = document.getElementsByClassName("myclass");
for (var i = 0; i < elements.length; i++) myFunction(elements[i]);

You need to edit your ~/.ssh/config file. Add something like the following:

Host example.com
    Port 1234

A quick google search shows a few different resources that explain it in more detail than me.

Give name and values to those submit buttons like:

    <td>
    <input type="submit" name='mybutton' class="noborder" id="save" value="save" alt="Save" tabindex="4" />
    </td>
    <td>
    <input type="submit" name='mybutton' class="noborder" id="publish" value="publish" alt="Publish" tabindex="5" />
    </td>

and then in your php script you could check

if($_POST['mybutton'] == 'save')
{
  ///do save processing
}
elseif($_POST['mybutton'] == 'publish')
{
  ///do publish processing here
}

I've been successful in getting this to work when I set the margins of the container to 0:

#container
{
   margin: 0 px;
}

in addition to all your other styles

You can build docker image from a file called docker file and named Dockerfile by default. It has set of command/instruction that you need in your docker container. Below command creates image with tag latest, Dockerfile should present on that location (. means present direcotry)

docker build . -t <image_name>:latest

You can specify the Dockerfile via -f if the file name in not default (Dockerfile) Sameple Docker file contents.

FROM busybox
RUN echo "hello world"

Try MySQL Workbench. It packs in very nice data modeling tools. Check out their screenshots for EER diagrams (Enhanced Entity Relationships, which are a notch up ER diagrams).

This isn't CakePHP specific, but you can modify the options so that the foreign keys and join tables follow the conventions that CakePHP uses. This would simplify your data modeling process once you've put the rules in place.

You can use a getter, so that your property is going to be reading only. Example:

export class MyClass {
    private _LEVELS = {
        level1: "level1",
        level2: "level2",
        level2: "level2"
    };

    public get STATUSES() {
        return this._LEVELS;
    }
}

Used in another class:

import { MyClass } from "myclasspath";
class AnotherClass {
    private myClass = new MyClass();

    tryLevel() {
       console.log(this.myClass.STATUSES.level1);
    }
}

I caught this error a few days ago.

IN my case it was because I was using a Transaction on a Singleton.

.Net does not work well with Singleton as stated above.

My solution was this:

public class DbHelper : DbHelperCore
{
    public DbHelper()
    {
        Connection = null;
        Transaction = null;
    }

    public static DbHelper instance
    {
        get
        {
            if (HttpContext.Current is null)
                return new DbHelper();
            else if (HttpContext.Current.Items["dbh"] == null)
                HttpContext.Current.Items["dbh"] = new DbHelper();

            return (DbHelper)HttpContext.Current.Items["dbh"];
        }
    }

    public override void BeginTransaction()
    {
        Connection = new SqlConnection(Entity.Connection.getCon);
        if (Connection.State == System.Data.ConnectionState.Closed)
            Connection.Open();
        Transaction = Connection.BeginTransaction();
    }
}

I used HttpContext.Current.Items for my instance. This class DbHelper and DbHelperCore is my own class

The java design of the "enhanced for loop" was to not expose the iterator to code, but the only way to safely remove an item is to access the iterator. So in this case you have to do it old school:

 for(Iterator<String> i = names.iterator(); i.hasNext();) {
       String name = i.next();
       //Do Something
       i.remove();
 }

If in the real code the enhanced for loop is really worth it, then you could add the items to a temporary collection and call removeAll on the list after the loop.

EDIT (re addendum): No, changing the list in any way outside the iterator.remove() method while iterating will cause problems. The only way around this is to use a CopyOnWriteArrayList, but that is really intended for concurrency issues.

The cheapest (in terms of lines of code) way to remove duplicates is to dump the list into a LinkedHashSet (and then back into a List if you need). This preserves insertion order while removing duplicates.

    // acos(0.0) will return value of pi/2, inverse of cos(0) is pi/2 
    double pi = 2 * acos(0.0);
    int n; // upto 6 digit
    scanf("%d",&n); //precision with which you want the value of pi
    printf("%.*lf\n",n,pi); // * will get replaced by n which is the required precision

To invoke a dry run:

make -n

This will show what make is attempting to do.

Here is representation of screen eclipse to make hierarachical.

There is no way to automatically set CMAKE_PREFIX_PATH in a way you want. I see following ways to solve this problem:

1. Put all libraries files in the same dir. That is, include/ would contain headers for all libs, lib/ - binaries, etc. FYI, this is common layout for most UNIX-like systems.

2. Set global environment variable CMAKE_PREFIX_PATH to D:/develop/cmake/libs/libA;D:/develop/cmake/libs/libB;.... When you run CMake, it would aautomatically pick up this env var and populate it's own CMAKE_PREFIX_PATH.

3. Write a wrapper .bat script, which would call cmake command with -D CMAKE_PREFIX_PATH=... argument.

To download file on flask call. File name is Examples.pdf When I am hitting 127.0.0.1:5000/download it should get download.

Example:

from flask import Flask
from flask import send_file
app = Flask(__name__)

@app.route('/download')
def downloadFile ():
    #For windows you need to use drive name [ex: F:/Example.pdf]
    path = "/Examples.pdf"
    return send_file(path, as_attachment=True)

if __name__ == '__main__':
    app.run(port=5000,debug=True) 

Its very late here but thought to share below code. If we have our WebApi as a different project altogether in the same solution then we can call the same from MVC controller like below

public class ProductsController : Controller
    {
        // GET: Products
        public async Task<ActionResult> Index()
        {
            string apiUrl = "http://localhost:58764/api/values";

            using (HttpClient client=new HttpClient())
            {
                client.BaseAddress = new Uri(apiUrl);
                client.DefaultRequestHeaders.Accept.Clear();
                client.DefaultRequestHeaders.Accept.Add(new System.Net.Http.Headers.MediaTypeWithQualityHeaderValue("application/json"));

                HttpResponseMessage response = await client.GetAsync(apiUrl);
                if (response.IsSuccessStatusCode)
                {
                    var data = await response.Content.ReadAsStringAsync();
                    var table = Newtonsoft.Json.JsonConvert.DeserializeObject<System.Data.DataTable>(data);

                }


            }
            return View();

        }
    }

If you are using windows, then take a look at this link. Otherwise, you may look for your OS specific version api. I don't think C++ comes with a cross-platform way to do it. At the end, it's NOT C++'s work, it's the OS's work.

or you can use:

a {
    display: inline-block;
  }

If you are using Python 3, you can use urllib.parse

url = """example.com?title=%D0%BF%D1%80%D0%B0%D0%B2%D0%BE%D0%B2%D0%B0%D1%8F+%D0%B7%D0%B0%D1%89%D0%B8%D1%82%D0%B0"""

import urllib.parse
urllib.parse.unquote(url)

gives:

'example.com?title=????????+??????'

Remember to pipe Observables to async, like *ngFor item of items$ | async, where you are trying to *ngFor item of items$ where items$ is obviously an Observable because you notated it with the $ similar to items$: Observable<IValuePair>, and your assignment may be something like this.items$ = this.someDataService.someMethod<IValuePair>() which returns an Observable of type T.

Adding to this... I believe I have used notation like *ngFor item of (items$ | async)?.someProperty

I just bumped into this problem, tried all above suggestions but still failed. Without repeat what have been suggested above, here are the things I (you) may be missing: In case you are using maven, likely you'll state the dependencies i.e:

<groupId>org.apache.derby</groupId>
<artifactId>derbyclient</artifactId>
<version>10.10.1.1</version>

Please be careful with the version. It must be compatible with the server instance you are running.

I solved my case by giving up on what maven dependencies provided and manually adding external jar from "%JAVA_HOME%\db\lib", the same source of my running server. In this case I'm testing using my Local.

So if you're testing with remote server instance, look for the derbyclient.jar that come with server package.

If you need to show and hide progress bar inside your php and java script, then follow this step.Its a complete solution, no need of any library etc.

           //Design Progress Bar

  <style>

{     
position: absolute;
left: 50%;
top: 50%;
background-color: white;
z-index: 100;

height: 200px;


width: 300px;
margin-left: -300px;

    /*Change your loading image here*/
   background: url(images/loading12.gif) 50% 50% no-repeat ;

}
  </style>

               //Progress Bar inside your Page

<div id="spinner" style=" display:none; ">
</div>                                

    // Button to show and Hide Progress Bar
<input class="submit" onClick="Show()" type="button" value="Show" /> 
<input class="submit" onClick="Hide()" type="button" value="Hide" /> 

            //Java Script Function to Handle Button Event

Vectors and matrices can only be of a single type and cbind and rbind on vectors will give matrices. In these cases, the numeric values will be promoted to character values since that type will hold all the values.

(Note that in your rbind example, the promotion happens within the c call:

> c(10, "[]", "[[1,2]]")
[1] "10"      "[]"      "[[1,2]]"

If you want a rectangular structure where the columns can be different types, you want a data.frame. Any of the following should get you what you want:

> x = data.frame(v1=c(10, 20), v2=c("[]", "[]"), v3=c("[[1,2]]","[[1,3]]"))
> x
  v1 v2      v3
1 10 [] [[1,2]]
2 20 [] [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ v1: num  10 20
 $ v2: Factor w/ 1 level "[]": 1 1
 $ v3: Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using specifically the data.frame version of cbind)

> x = cbind.data.frame(c(10, 20), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c(10, 20) c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c(10, 20)              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1
 $ c("[[1,2]]", "[[1,3]]"): Factor w/ 2 levels "[[1,2]]","[[1,3]]": 1 2

or (using cbind, but making the first a data.frame so that it combines as data.frames do):

> x = cbind(data.frame(c(10, 20)), c("[]", "[]"), c("[[1,2]]","[[1,3]]"))
> x
  c.10..20. c("[]", "[]") c("[[1,2]]", "[[1,3]]")
1        10            []                 [[1,2]]
2        20            []                 [[1,3]]
> str(x)
'data.frame':   2 obs. of  3 variables:
 $ c.10..20.              : num  10 20
 $ c("[]", "[]")          : Factor w/ 1 level "[]": 1 1

The naive algorithm, which is what you've got once you correct it as noted in comments, is O(n^3).

There do exist algorithms that reduce this somewhat, but you're not likely to find an O(n^2) implementation. I believe the question of the most efficient implementation is still open.

See this wikipedia article on Matrix Multiplication for more information.

Numpy is required by pandas (and by virtually all numerical tools for Python). Scipy is not strictly required for pandas but is listed as an "optional dependency". I wouldn't say that pandas is an alternative to Numpy and/or Scipy. Rather, it's an extra tool that provides a more streamlined way of working with numerical and tabular data in Python. You can use pandas data structures but freely draw on Numpy and Scipy functions to manipulate them.

Sweet alerts also has an 'html' option, set it to true.

var hh = "<b>test</b>";
swal({
    title: "" + txt + "", 
    html: true,
    text: "Testno  sporocilo za objekt " + hh + "",  
    confirmButtonText: "V redu", 
    allowOutsideClick: "true" 
});

Call decode() on a bytes instance to get the text which it encodes.

str = bytes.decode()

Try this

if ( typeof is_json != "function" )
function is_json( _obj )
{
    var _has_keys = 0 ;
    for( var _pr in _obj )
    {
        if ( _obj.hasOwnProperty( _pr ) && !( /^\d+$/.test( _pr ) ) )
        {
           _has_keys = 1 ;
           break ;
        }
    }

    return ( _has_keys && _obj.constructor == Object && _obj.constructor != Array ) ? 1 : 0 ;
}

It works for the example below

var _a = { "name" : "me",
       "surname" : "I",
       "nickname" : {
                      "first" : "wow",
                      "second" : "super",
                      "morelevel" : {
                                      "3level1" : 1,
                                      "3level2" : 2,
                                      "3level3" : 3
                                    }
                    }
     } ;

var _b = [ "name", "surname", "nickname" ] ;
var _c = "abcdefg" ;

console.log( is_json( _a ) );
console.log( is_json( _b ) );
console.log( is_json( _c ) );

It's a bit late but I came across this post.

It's not perfect but here's what I do.

HTML Code

<div class="showcase-menu-social"><img class="margin-left-20" src="images/graphics/facebook-50x50.png" alt="facebook-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/twitter-50x50.png" alt="twitter-50x50" width="50" height="50" /><img class="margin-left-20" src="images/graphics/youtube-50x50.png" alt="youtube-50x50" width="50" height="50" /></div>

CSS Code

.showcase-menu {
  margin-left:20px;
    margin-right:20px;
    padding: 0px 20px 0px 20px;
    background-color: #C37500;
    behavior: url(/css/border-radius.htc);
  border-radius: 20px;
    }

.showcase-menu-social img:hover {
  background-color: #C37500;
  opacity:0.7 !important;
  filter:alpha(opacity=70) !important; /* For IE8 and earlier */
  box-shadow: 0 0 0px #000000 !important;
}

Now my border radius of 20px matches up exactly with the image border radius. As you can see the .showcase-menu has the same background as the .showcase-menu-social. What this does is to allow the 'opacity' to take effect and no 'square' background or border shows, thus the image slightly reduces it's saturation on hover.

It's a nice effect and does give the viewer the feedback that the image is in focus. I'm fairly sure on a darker background, it would have even a better effect.

The nice thing is that this is valid HTML-CSS code and will validate. To be honest, it should work on non-image elements just as good as images.

Enjoy!

if(document.readyState === 'complete') {
    DoStuffFunction();
} else {
    if (window.addEventListener) {  
        window.addEventListener('load', DoStuffFunction, false);
    } else {
        window.attachEvent('onload', DoStuffFunction);
    }
}

You can chain .fail() callback for error response.

$.get('http://example.com/page/2/', function(data){ 
   $(data).find('#reviews .card').appendTo('#reviews');
})
.fail(function() {
  //Error logic
})

set "html" option to true if you want to have html into tooltip. Actual html is determined by option "title" (link's title attribute shouldn't be set)

$('#example1').tooltip({placement: 'bottom', title: '<p class="testtooltip">par</p>', html: true});

Live sample

Better still (or shorter anyway):

SUM(ccc_news_comments.id = 'approved')

This works since the Boolean type in MySQL is represented as INT 0 and 1, just like in C. (May not be portable across DB systems though.)

As for COALESCE() as mentioned in other answers, many language APIs automatically convert NULL to '' when fetching the value. For example with PHP's mysqli interface it would be safe to run your query without COALESCE().

Use $_SERVER['REQUEST_METHOD'].

I use int in the event that Microsoft changes the default implementation for an integer to some new fangled version (let's call it Int32b).

Microsoft can then change the int alias to Int32b, and I don't have to change any of my code to take advantage of their new (and hopefully improved) integer implementation.

The same goes for any of the type keywords.

Variables are not defined, but declared.

This is possible duplicate of declare variables in a pl/sql block

But you can look here :

You need to add an instance of the class:

lstemail.Add(new EmailData { FirstName = "John", LastName = "Smith", Location = "Los Angeles"});

I would recommend adding a constructor to your class, however:

public class EmailData
{
    public EmailData(string firstName, string lastName, string location)
    {
        this.FirstName = firstName;
        this.LastName = lastName;
        this.Location = location;
    }
    public string FirstName{ set; get; }
    public string LastName { set; get; }
    public string Location{ set; get; }
}

This would allow you to write the addition to your list using the constructor:

lstemail.Add(new EmailData("John", "Smith", "Los Angeles"));

Even though this isn't entirely in the SO spirit, I love this question, because I had the same trouble when I started, so I'll give you a quick guide. Obviously you don't understand the principles behind them (don't take it as an offense, but if you did you wouldn't be asking).

Django is server-side. It means, say a client goes to a URL, you have a function inside views that renders what he sees and returns a response in HTML. Let's break it up into examples:

views.py:

def hello(request):
    return HttpResponse('Hello World!')

def home(request):
    return render_to_response('index.html', {'variable': 'world'})

index.html:

<h1>Hello {{ variable }}, welcome to my awesome site</h1>

urls.py:

url(r'^hello/', 'myapp.views.hello'),
url(r'^home/', 'myapp.views.home'),

That's an example of the simplest of usages. Going to 127.0.0.1:8000/hello means a request to the hello() function, going to 127.0.0.1:8000/home will return the index.html and replace all the variables as asked (you probably know all this by now).

Now let's talk about AJAX. AJAX calls are client-side code that does asynchronous requests. That sounds complicated, but it simply means it does a request for you in the background and then handles the response. So when you do an AJAX call for some URL, you get the same data you would get as a user going to that place.

For example, an AJAX call to 127.0.0.1:8000/hello will return the same thing it would as if you visited it. Only this time, you have it inside a JavaScript function and you can deal with it however you'd like. Let's look at a simple use case:

$.ajax({
    url: '127.0.0.1:8000/hello',
    type: 'get', // This is the default though, you don't actually need to always mention it
    success: function(data) {
        alert(data);
    },
    failure: function(data) { 
        alert('Got an error dude');
    }
}); 

The general process is this:

1. The call goes to the URL 127.0.0.1:8000/hello as if you opened a new tab and did it yourself.
2. If it succeeds (status code 200), do the function for success, which will alert the data received.
3. If fails, do a different function.

Now what would happen here? You would get an alert with 'hello world' in it. What happens if you do an AJAX call to home? Same thing, you'll get an alert stating <h1>Hello world, welcome to my awesome site</h1>.

In other words - there's nothing new about AJAX calls. They are just a way for you to let the user get data and information without leaving the page, and it makes for a smooth and very neat design of your website. A few guidelines you should take note of:

1. Learn jQuery. I cannot stress this enough. You're gonna have to understand it a little to know how to handle the data you receive. You'll also need to understand some basic JavaScript syntax (not far from python, you'll get used to it). I strongly recommend Envato's video tutorials for jQuery, they are great and will put you on the right path.
2. When to use JSON?. You're going to see a lot of examples where the data sent by the Django views is in JSON. I didn't go into detail on that, because it isn't important how to do it (there are plenty of explanations abound) and a lot more important when. And the answer to that is - JSON data is serialized data. That is, data you can manipulate. Like I mentioned, an AJAX call will fetch the response as if the user did it himself. Now say you don't want to mess with all the html, and instead want to send data (a list of objects perhaps). JSON is good for this, because it sends it as an object (JSON data looks like a python dictionary), and then you can iterate over it or do something else that removes the need to sift through useless html.
3. Add it last. When you build a web app and want to implement AJAX - do yourself a favor. First, build the entire app completely devoid of any AJAX. See that everything is working. Then, and only then, start writing the AJAX calls. That's a good process that helps you learn a lot as well.
4. Use chrome's developer tools. Since AJAX calls are done in the background it's sometimes very hard to debug them. You should use the chrome developer tools (or similar tools such as firebug) and console.log things to debug. I won't explain in detail, just google around and find out about it. It would be very helpful to you.
5. CSRF awareness. Finally, remember that post requests in Django require the csrf_token. With AJAX calls, a lot of times you'd like to send data without refreshing the page. You'll probably face some trouble before you'd finally remember that - wait, you forgot to send the csrf_token. This is a known beginner roadblock in AJAX-Django integration, but after you learn how to make it play nice, it's easy as pie.

That's everything that comes to my head. It's a vast subject, but yeah, there's probably not enough examples out there. Just work your way there, slowly, you'll get it eventually.

1. Open xls file with a hex editor.
2. Search for DPB
3. Replace DPB to DPx
4. Save file.
5. Open file in Excel.
6. Click "Yes" if you get any message box.
7. Set new password from VBA Project Properties.
8. Close and open again file, then type your new password to unprotect.

...this is obviously performing a 'string' comparison

No - if the date/time format matches the supported format, MySQL performs implicit conversion to convert the value to a DATETIME, based on the column it is being compared to. Same thing happens with:

WHERE int_column = '1'

...where the string value of "1" is converted to an INTeger because int_column's data type is INT, not CHAR/VARCHAR/TEXT.

If you want to explicitly convert the string to a DATETIME, the STR_TO_DATE function would be the best choice:

WHERE expires_at <= STR_TO_DATE('2010-10-15 10:00:00', '%Y-%m-%d %H:%i:%s')

If you are mocking the behavior (with something like doNothing()) there should really be no need to call to verify*(). That said, here's my stab at re-writing your test method:

@PrepareForTest({InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest { //Note the renaming of the test class.
   public void testProcessOrder() {
        //Variables
        InternalService is = new InternalService();
        Order order = mock(Order.class);

        //Mock Behavior
        when(order.isSuccessful()).thenReturn(true);
        mockStatic(Internalutils.class);
        doNothing().when(InternalUtils.class); //This is the preferred way
                                               //to mock static void methods.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

        //Execute
        is.processOrder(order);            

        //Verify
        verifyStatic(InternalUtils.class); //Similar to how you mock static methods
                                           //this is how you verify them.
        InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());
   }
}

I grouped into four sections to better highlight what is going on:

1. Variables

I choose to declare any instance variables / method arguments / mock collaborators here. If it is something used in multiple tests, consider making it an instance variable of the test class.

2. Mock Behavior

This is where you define the behavior of all of your mocks. You're setting up return values and expectations here, prior to executing the code under test. Generally speaking, if you set the mock behavior here you wouldn't need to verify the behavior later.

3. Execute

Nothing fancy here; this just kicks off the code being tested. I like to give it its own section to call attention to it.

4. Verify

This is when you call any method starting with verify or assert. After the test is over, you check that the things you wanted to have happen actually did happen. That is the biggest mistake I see with your test method; you attempted to verify the method call before it was ever given a chance to run. Second to that is you never specified which static method you wanted to verify.

Additional Notes

This is mostly personal preference on my part. There is a certain order you need to do things in but within each grouping there is a little wiggle room. This helps me quickly separate out what is happening where.

I also highly recommend going through the examples at the following sites as they are very robust and can help with the majority of the cases you'll need:

• https://github.com/powermock/powermock/wiki/Mockito (PowerMock Overview / Examples)
• http://site.mockito.org/mockito/docs/current/org/mockito/Mockito.html (Mockito Overview / Examples)

You say it "works fine in a standalone program," but that you get "unusual difference values" when you "include this into my logic to read from report". That suggests that your report has some values for which it doesn't work correctly, and your standalone program doesn't have those values. Instead of a standalone program, I suggest a test case. Write a test case much as you would a standalone program, subclassing from JUnit's TestCase class. Now you can run a very specific example, knowing what value you expect (and don't give it today for the test value, because today changes over time). If you put in the values you used in the standalone program, your tests will probably pass. That's great - you want those cases to keep working. Now, add a value from your report, one that doesn't work right. Your new test will probably fail. Figure out why it's failing, fix it, and get to green (all tests passing). Run your report. See what's still broken; write a test; make it pass. Pretty soon you'll find your report is working.

just call startForeground method immediately after Service or IntentService is Created. like this:

import android.app.Notification;
public class AuthenticationService extends Service {

    @Override
    public void onCreate() {
        super.onCreate();
        startForeground(1,new Notification());
    }
}

Similar error with Glassfish 4.0 and several JDK installed:

SEVERE: GlassFish requires JDK 7, you are using JDK version 6.

There is no AS_JAVA reference in "C:\glassfish\config\asenv.bat" by default. After adding manually

set AS_JAVA=C:\Program Files\Java\jdk1.7.0_25 

it works.

Depending on the compelexity of your Account object, I would recomend either XML or Flat file.

If there are just a couple of values to store for each account, you could store them on a properties file, like this:

account.1.somekey=Some value
account.1.someotherkey=Some other value
account.1.somedate=2009-12-21
account.2.somekey=Some value 2
account.2.someotherkey=Some other value 2

... and so forth. Reading from a properties file should be easy, as it maps directly to a string dictionary.

As to where to store this file, the best choise would be to store into AppData folder, inside a subfolder for your program. This is a location where current users will always have access to write, and it's kept safe from other users by the OS itself.

You can use:

nslookup www.example.com

As Kyle suggested, you can measure the client browser viewport size without taking into account the size of the scroll bars this way.

Sample (Viewport dimensions WITHOUT scroll bars)

// First you forcibly request the scroll bars to hidden regardless if they will be needed or not.
$('body').css('overflow', 'hidden');

// Take your measures.
// (These measures WILL NOT take into account scroll bars dimensions)
var heightNoScrollBars = $(window).height();
var widthNoScrollBars = $(window).width();

// Set the overflow css property back to it's original value (default is auto)
$('body').css('overflow', 'auto');

Alternatively if you wish to find the dimensions of the client viewport while taking into account the size of the scroll bars, then this sample bellow best suits you.

First don't forget to set you body tag to be 100% width and height just to make sure the measurement is accurate.

body { 
width: 100%; // if you wish to measure the width and take into account the horizontal scroll bar.
height: 100%; // if you wish to measure the height while taking into account the vertical scroll bar.
}

Sample (Viewport dimensions WITH scroll bars)

// First you forcibly request the scroll bars to be shown regardless if they will be needed or not.
$('body').css('overflow', 'scroll');

// Take your measures.
// (These measures WILL take into account scroll bars dimensions)
var heightWithScrollBars = $(window).height();
var widthWithScrollBars = $(window).width();

// Set the overflow css property back to it's original value (default is auto)
$('body').css('overflow', 'auto');

Single bash line:

sed -n $((1+$RANDOM%`wc -l test.txt | cut -f 1 -d ' '`))p test.txt

Slight problem: duplicate filename.

I guess you want to decide which of 4:3 and 16:9 is the best fit.

function getAspectRatio(width, height) {
    var ratio = width / height;
    return ( Math.abs( ratio - 4 / 3 ) < Math.abs( ratio - 16 / 9 ) ) ? '4:3' : '16:9';
}

My configuration was like this. I had a QuartzJob , a Service Bean , and Dao . as usual it was configured with LocalSessionFactoryBean (for hibernate) , and SchedulerFactoryBean for Quartz framework. while writing the Quartz job , I by mistake annotated it with @Service , I should not have done that because I was using another strategy to wire the QuartzBean using AutowiringSpringBeanJobFactory extending SpringBeanJobFactory.

So what actually was happening is that due to Quartz Autowire , TX was getting injected to the Job Bean and at the same time Tx Context was set by virtue of @Service annotation and hence the TX was falling out of sync !!

I hope it help to those for whom above solutions really didn't solved the issue. I was using Spring 4.2.5 and Hibernate 4.0.1 ,

I see that in this thread there is a unnecessary suggestion to add @Transactional annotation to the DAO(@Repository) , that is a useless suggestion cause @Repository has all what it needs to have don't have to specially set that @transactional on DAOs , as the DAOs are called from the services which have already being injected by @Trasancational . I hope this might be helpful people who are using Quartz , Spring and Hibernate together.

Android's callOnClick() (added in API 15) can sometimes be a better choice in my experience than performClick(). If a user has selection sounds enabled, then performClick() could cause the user to hear two continuous selection sounds that are somewhat layered on top of each other which can be jarring. (One selection sound for the user's first button click, and then another for the other button's OnClickListener that you're calling via code.)

Another approach is to use ls when reading the file list within a directory so as to give you what you want, i.e. "just the file name/s". As opposed to reading the full file path and then extracting the "file name" component in the body of the for loop.

Example below that follows your original:

for filename in $(ls /home/user/)
do
  echo $filename
done;

If you are running the script in the same directory as the files, then it simply becomes:

for filename in $(ls)
do
  echo $filename
done;

Go to your client machine and type in:

nslookup server.company.com

substituting the real host name of your server for server.company.com, of course.

That should tell you which DNS server your client is using (if any) and what it thinks the problem is with the name.

To force an application to use an IP address, generally you just configure it to use the IP address instead of a host name. If the host name is hard-coded, or the application insists on using a host name in preference to an IP address (as one of your other comments seems to indicate), then you're probably out of luck there.

However, you can change the way that most machine resolve the host names, such as with /etc/resolv.conf and /etc/hosts on UNIXy systems and a local hosts file on Windows-y systems.

Whenever multiple values are returned from a function in python, does it always convert the multiple values to a list of multiple values and then returns it from the function??

I'm just adding a name and print the result that returns from the function. the type of result is 'tuple'.

  class FigureOut:
   first_name = None
   last_name = None
   def setName(self, name):
      fullname = name.split()
      self.first_name = fullname[0]
      self.last_name = fullname[1]
      self.special_name = fullname[2]
   def getName(self):
      return self.first_name, self.last_name, self.special_name

f = FigureOut()
f.setName("Allen Solly Jun")
name = f.getName()
print type(name)

I don't know whether you have heard about 'first class function'. Python is the language that has 'first class function'

I hope my answer could help you. Happy coding.

NOTE: I intend to make this a "one stop post" where you can use the Correct way to find the last row. This will also cover the best practices to follow when finding the last row. And hence I will keep on updating it whenever I come across a new scenario/information.

Unreliable ways of finding the last row

Some of the most common ways of finding last row which are highly unreliable and hence should never be used.

1. UsedRange
2. xlDown
3. CountA

UsedRange should NEVER be used to find the last cell which has data. It is highly unreliable. Try this experiment.

Type something in cell A5. Now when you calculate the last row with any of the methods given below, it will give you 5. Now color the cell A10 red. If you now use the any of the below code, you will still get 5. If you use Usedrange.Rows.Count what do you get? It won't be 5.

Here is a scenario to show how UsedRange works.

xlDown is equally unreliable.

Consider this code

lastrow = Range("A1").End(xlDown).Row

What would happen if there was only one cell (A1) which had data? You will end up reaching the last row in the worksheet! It's like selecting cell A1 and then pressing End key and then pressing Down Arrow key. This will also give you unreliable results if there are blank cells in a range.

CountA is also unreliable because it will give you incorrect result if there are blank cells in between.

And hence one should avoid the use of UsedRange, xlDown and CountA to find the last cell.

Find Last Row in a Column

To find the last Row in Col E use this

With Sheets("Sheet1")
    LastRow = .Range("E" & .Rows.Count).End(xlUp).Row
End With

If you notice that we have a . before Rows.Count. We often chose to ignore that. See THIS question on the possible error that you may get. I always advise using . before Rows.Count and Columns.Count. That question is a classic scenario where the code will fail because the Rows.Count returns 65536 for Excel 2003 and earlier and 1048576 for Excel 2007 and later. Similarly Columns.Count returns 256 and 16384, respectively.

The above fact that Excel 2007+ has 1048576 rows also emphasizes on the fact that we should always declare the variable which will hold the row value as Long instead of Integer else you will get an Overflow error.

Note that this approach will skip any hidden rows. Looking back at my screenshot above for column A, if row 8 were hidden, this approach would return 5 instead of 8.

Find Last Row in a Sheet

To find the Effective last row in the sheet, use this. Notice the use of Application.WorksheetFunction.CountA(.Cells). This is required because if there are no cells with data in the worksheet then .Find will give you Run Time Error 91: Object Variable or With block variable not set

With Sheets("Sheet1")
    If Application.WorksheetFunction.CountA(.Cells) <> 0 Then
        lastrow = .Cells.Find(What:="*", _
                      After:=.Range("A1"), _
                      Lookat:=xlPart, _
                      LookIn:=xlFormulas, _
                      SearchOrder:=xlByRows, _
                      SearchDirection:=xlPrevious, _
                      MatchCase:=False).Row
    Else
        lastrow = 1
    End If
End With

Find Last Row in a Table (ListObject)

The same principles apply, for example to get the last row in the third column of a table:

Sub FindLastRowInExcelTableColAandB()
Dim lastRow As Long
Dim ws As Worksheet, tbl as ListObject
Set ws = Sheets("Sheet1")  'Modify as needed
'Assuming the name of the table is "Table1", modify as needed
Set tbl = ws.ListObjects("Table1")

With tbl.ListColumns(3).Range
    lastrow = .Find(What:="*", _
                After:=.Cells(1), _

Short answer:

int uses up 4 bytes of memory (and it CANNOT contain a decimal), double uses 8 bytes of memory. Just different tools for different purposes.

matches(); does not buffer, but find() buffers. find() searches to the end of the string first, indexes the result, and return the boolean value and corresponding index.

That is why when you have a code like

1:Pattern.compile("[a-z]");

2:Pattern.matcher("0a1b1c3d4");

3:int count = 0;

4:while(matcher.find()){

5:count++: }

At 4: The regex engine using the pattern structure will read through the whole of your code (index to index as specified by the regex[single character] to find at least one match. If such match is found, it will be indexed then the loop will execute based on the indexed result else if it didn't do ahead calculation like which matches(); does not. The while statement would never execute since the first character of the matched string is not an alphabet.

Here's a generic solution that keeps the child element in the document flow:

.child {
  width: 100vw;
  position: relative;
  left: calc(-50vw + 50%);
}

We set the width of the child element to fill the entire viewport width, then we make it meet the edge of the screen by moving it to the left by a distance of half the viewport, minus 50% of the parent element's width.

Demo:

* {
  box-sizing: border-box;
}

body {
  margin: 0;
  overflow-x: hidden;
}

.parent {
  max-width: 400px;
  margin: 0 auto;
  padding: 1rem;
  position: relative;
  background-color: darkgrey;
}

.child {
  width: 100vw;
  position: relative;
  left: calc(-50vw + 50%);

  height: 100px;
  border: 3px solid red;
  background-color: lightgrey;
}

<div class="parent">
  Pre
  <div class="child">Child</div>
  Post
</div>

Browser support for vw and for calc() can generally be seen as IE9 and newer.

Note: This assumes the box model is set to border-box. Without border-box, you would also have to subtract paddings and borders, making this solution a mess.

Note: It is encouraged to hide horizontal overflow of your scrolling container, as certain browsers may choose to display a horizontal scrollbar despite there being no overflow.

I found out an easier way.

• go to File -> Settings -> Keymap
• Search for Execute Selection in Console and reassign it to a new shortcut, like Crl + Enter.

This is the same shortcut to the same action in Spyder and R-Studio.

connect your server from mysqlworkbench and run this command-> ALTER USER 'root'@'localhost' IDENTIFIED BY 'yourpassword';

The top ranked answer to this question suggests using the readLine() method to take in user input from the command line. However, I want to note that you need to use the ! operator when calling this method to return a string instead of an optional:

var response = readLine()!

A bit too late but I got the same issue and fixed it switching schemalocation into schemaLocation in the persistence.xml file (line 1).

Be in the directory where you need to perform the renaming.

import os
# get the file name list to nameList
nameList = os.listdir() 
#loop through the name and rename
for fileName in nameList:
    rename=fileName[15:28]
    os.rename(fileName,rename)
#example:
#input fileName bulk like :20180707131932_IMG_4304.JPG
#output renamed bulk like :IMG_4304.JPG

Use Collections.list(iterator).stream()...

If you have it in a string, you can use .split() to separate them.

>>> for string in ('Mike 18', 'Kevin 35', 'Angel 56'):
...   l = string.split()
...   print repr(l[0]), repr(int(l[1]))
...
'Mike' 18
'Kevin' 35
'Angel' 56
>>>

Alternative way to check would be:

if (!$('#myModal').is(':visible')) {
    // if modal is not shown/visible then do something
}

On Chrome's latest update (38.0.2125.104 m at the moment), Google added the option to know whether the files loaded to the website were newly downloaded from the server - or read from the local cache.

When an error like yours "hits" the console - you know the files were just downloaded from the server and not read from the local cache. You can recreate this error by clicking Ctrl + F5 (refresh and erase cache).

It fits your description where Firebug (or equivalents) doesn't fire any errors to the console - whilst Chrome does.

So, the bottom line is - your're just fine and you can ignore this error - it's merely an indicator.

You can also use showdialog

Private Sub Button3_Click(sender As System.Object, e As System.EventArgs) _
                      Handles Button3.Click

     dim mydialogbox as new aboutbox1
     aboutbox1.showdialog()

End Sub

Yes, this is possible.

<form id="formName" action="<?php echo $_SERVER['PHP_SELF'];?>" method="get">
    <input type ="checkbox" name="cBox[]" value = "3" onchange="document.getElementById('formName').submit()">3</input>
    <input type ="checkbox" name="cBox[]" value = "4" onchange="document.getElementById('formName').submit()">4</input>
    <input type ="checkbox" name="cBox[]" value = "5" onchange="document.getElementById('formName').submit()">5</input>
    <input type="submit" name="submit" value="Search" />
</form>

By adding onchange="document.getElementById('formName').submit()" to each checkbox, you'll submit any time a checkbox is changed.

If you're OK with jQuery, it's even easier (and unobtrusive):

$(document).ready(function(){
    $("#formname").on("change", "input:checkbox", function(){
        $("#formname").submit();
    });
});

For any number of checkboxes in your form, when the "change" event happens, the form is submitted. This will even work if you dynamically create more checkboxes thanks to the .on() method.

mac os x don't use com numbers. you have to use something like 'ser:devicename' , 9600

To use support libraries starting from version 26.0.0 you need to add Google's Maven repository to your project's build.gradle file as described here: https://developer.android.com/topic/libraries/support-library/setup.html

allprojects {
        repositories {
            jcenter()
            maven {
                url "https://maven.google.com"
            }
        }
    }

For Android Studio 3.0.0 and above:

allprojects {
        repositories {
            jcenter()
            google()
        }
    }

Simply

$os = array("Mac", "NT", "Irix", "Linux");
if (!in_array("BB", $os)) {
    echo "BB is not found";
}

This works for me

cd "C:\Program Files\SmartBear\SoapUI-5.6.0\bin"

start SoapUI-5.6.0.exe -w "C:\DATA\SoapUi\Workspaces\Production-workspace.xml"

exit

Unless there is some other requirement not specified, I would simply convert your color image to grayscale and work with that only (no need to work on the 3 channels, the contrast present is too high already). Also, unless there is some specific problem regarding resizing, I would work with a downscaled version of your images, since they are relatively large and the size adds nothing to the problem being solved. Then, finally, your problem is solved with a median filter, some basic morphological tools, and statistics (mostly for the Otsu thresholding, which is already done for you).

Here is what I obtain with your sample image and some other image with a sheet of paper I found around:

The median filter is used to remove minor details from the, now grayscale, image. It will possibly remove thin lines inside the whitish paper, which is good because then you will end with tiny connected components which are easy to discard. After the median, apply a morphological gradient (simply dilation - erosion) and binarize the result by Otsu. The morphological gradient is a good method to keep strong edges, it should be used more. Then, since this gradient will increase the contour width, apply a morphological thinning. Now you can discard small components.

At this point, here is what we have with the right image above (before drawing the blue polygon), the left one is not shown because the only remaining component is the one describing the paper:

Given the examples, now the only issue left is distinguishing between components that look like rectangles and others that do not. This is a matter of determining a ratio between the area of the convex hull containing the shape and the area of its bounding box; the ratio 0.7 works fine for these examples. It might be the case that you also need to discard components that are inside the paper, but not in these examples by using this method (nevertheless, doing this step should be very easy especially because it can be done through OpenCV directly).

For reference, here is a sample code in Mathematica:

f = Import["http://thwartedglamour.files.wordpress.com/2010/06/my-coffee-table-1-sa.jpg"]
f = ImageResize[f, ImageDimensions[f][[1]]/4]
g = MedianFilter[ColorConvert[f, "Grayscale"], 2]
h = DeleteSmallComponents[Thinning[
     Binarize[ImageSubtract[Dilation[g, 1], Erosion[g, 1]]]]]
convexvert = ComponentMeasurements[SelectComponents[
     h, {"ConvexArea", "BoundingBoxArea"}, #1 / #2 > 0.7 &], 
     "ConvexVertices"][[All, 2]]
(* To visualize the blue polygons above: *)
Show[f, Graphics[{EdgeForm[{Blue, Thick}], RGBColor[0, 0, 1, 0.5], 
     Polygon @@ convexvert}]]

If there are more varied situations where the paper's rectangle is not so well defined, or the approach confuses it with other shapes -- these situations could happen due to various reasons, but a common cause is bad image acquisition -- then try combining the pre-processing steps with the work described in the paper "Rectangle Detection based on a Windowed Hough Transform".

Try this:

String urle = HOST + url + value;

Then return the values from:

urle.replace(" ", "%20").trim();

solution is

import time
import datetime
d = datetime.date(2015,1,5)

unixtime = time.mktime(d.timetuple())

You can always use iptables to delete the rules. If you have a lot of rules, just output them using the following command.

iptables-save > myfile

vi to edit them from the commend line. Just use the "dd" to delete the lines you no longer want.

iptables-restore < myfile and you're good to go.  

REMEMBER THAT IF YOU DON'T CONFIGURE YOUR OS TO SAVE THE RULES TO A FILE AND THEN LOAD THE FILE DURING THE BOOT THAT YOUR RULES WILL BE LOST.

You are passing hello() as a string, also hello() means execute hello immediately.

try

onClick={hello}

As others have said, you can use a DateTime and ignore the date, or use a TimeSpan. Personally I'm not keen on either of these solutions, as neither type really reflects the concept you're trying to represent - I regard the date/time types in .NET as somewhat on the sparse side which is one of the reasons I started Noda Time. In Noda Time, you can use the LocalTime type to represent a time of day.

One thing to consider: the time of day is not necessarily the length of time since midnight on the same day...

(As another aside, if you're also wanting to represent a closing time of a shop, you may find that you want to represent 24:00, i.e. the time at the end of the day. Most date/time APIs - including Noda Time - don't allow that to be represented as a time-of-day value.)

You should check the $GOPATH directory. If there is an empty directory of the package name, go get doesn't download the package from the repository.

For example, If I want to get the github.com/googollee/go-socket.io package from it's github repository, and there is already an empty directory github.com/googollee/go-socket.io in the $GOPATH, go get doesn't download the package and then complains that there is no buildable Go source file in the directory. Delete any empty directory first of all.

If you using webpack in your application, you can simply set it there, using DefinePlugin...

So in your plugin section, set the NODE_ENV to production:

plugins: [
  new webpack.DefinePlugin({
    'process.env.NODE_ENV': '"production"',
  })
]

<div id="clockbox" style="font:14pt Arial; color:#FF0000;text-align: center; border:1px solid red;background:cyan; height:50px;padding-top:12px;"></div>

Enums are just like Classes in that they are typed. Your current code just checks if it is an Enum without specifying what type of Enum it is a part of.

Because you haven't specified the type of the enum, you will have to use reflection to find out what the list of enum values is.

You can do it like so:

enumValue.getDeclaringClass().getEnumConstants() 

This will return an array of Enum objects, with each being one of the available options.

Just for convenience:

template<class V, typename T>
bool in(const V &v, const T &el) {
    return std::find(v.begin(), v.end(), el) != v.end();
}

The actual splitting based on multiple delimiters:

std::vector<std::string> split(const std::string &s,
                               const std::vector<char> &delims) {
    std::vector<std::string> res;
    auto stuff = [&delims](char c) { return !in(delims, c); };
    auto space = [&delims](char c) { return in(delims, c); };
    auto first = std::find_if(s.begin(), s.end(), stuff);
    while (first != s.end()) {
        auto last = std::find_if(first, s.end(), space);
        res.push_back(std::string(first, last));
        first = std::find_if(last + 1, s.end(), stuff);
    }
    return res;
}

The usage:

int main() {
    std::string s = "   aaa,  bb  cc ";
    for (auto el: split(s, {' ', ','}))
        std::cout << el << std::endl;
    return 0;
}

That happens because you're setting the src of the ImageView instead of the background.

Use this instead:

qImageView.setBackgroundResource(R.drawable.thumbs_down);

Here's a thread that talks about the differences between the two methods.

In my case I was trying to show a DialogFragment containing a pager and this exception was thrown when the FragmentPagerAdapter attempted to add the Fragments to the pager. Based on howettl answer I guess that it was due to the Pager parent was not the view set in setContentView() in my FragmentActivity.

The only change I did to solve the problem was to create the FragmentPagerAdapter passing in a FragmentMager obtained by calling getChildFragmentManager(), not the one obtained by calling getFragmentManager() as I normally do.

    public class PagerDialog extends DialogFragment{

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.pager_dialog, container, false);

        MyPagerAdapter pagerAdapter = new MyPagerAdapter(getChildFragmentManager());
        ViewPager pager = (ViewPager) rootView.findViewById(R.id.pager);
        pager.setAdapter(pagerAdapter);

        return rootView;
    }
}

In a command prompt:

$ git --version

In bash, contrary to [, [[ prevents word splitting of variable values.

If you already install the correct Android SDK Platform-Tools (Build Tool) and you still get an error, try to invalidate the cache; File -> Invalidate caches / Restart....

Use repr:

a = "Hello\tWorld\nHello World"
print(repr(a))
# 'Hello\tWorld\nHello World'

Note you do not get \s for a space. I hope that was a typo...?

But if you really do want \s for spaces, you could do this:

print(repr(a).replace(' ',r'\s'))

You can add new function to your jQuery library by adding these line on your own script file and you can easily use fadeSlideRight() and fadeSlideLeft().

Note: you can change width of animation as you like instance of 750px.

$.fn.fadeSlideRight = function(speed,fn) {
    return $(this).animate({
        'opacity' : 1,
        'width' : '750px'
    },speed || 400, function() {
        $.isFunction(fn) && fn.call(this);
    });
}

$.fn.fadeSlideLeft = function(speed,fn) {
    return $(this).animate({
        'opacity' : 0,
        'width' : '0px'
    },speed || 400,function() {
        $.isFunction(fn) && fn.call(this);
    });
}

You can iterate through each and every node and see if a node exists.

doc.Load(xmlPath);
        XmlNodeList node = doc.SelectNodes("//Nodes/Node");
        foreach (XmlNode chNode in node)
        {
            try{
            if (chNode["innerNode"]==null)
                return true; //node exists
            //if ... check for any other nodes you need to
            }catch(Exception e){return false; //some node doesn't exists.}
        }

You iterate through every Node elements under Nodes (say this is root) and check to see if node named 'innerNode' (add others if you need) exists. try..catch is because I suspect this will throw popular 'object reference not set' error if the node does not exist.

Better code with adding a subclass AuthorizeRole.cs

    [AttributeUsage(AttributeTargets.Method | AttributeTargets.Class, Inherited = true, AllowMultiple = true)]
    class AuthorizeRoleAttribute : AuthorizeAttribute
    {
        public AuthorizeRoleAttribute(params Rolenames[] roles)
        {
            this.Roles = string.Join(",", roles.Select(r => Enum.GetName(r.GetType(), r)));
        }
        protected override void HandleUnauthorizedRequest(System.Web.Mvc.AuthorizationContext filterContext)
        {
            if (filterContext.HttpContext.Request.IsAuthenticated)
            {
                filterContext.Result = new RedirectToRouteResult(
                new RouteValueDictionary {
                  { "action", "Unauthorized" },
                  { "controller", "Home" },
                  { "area", "" }
                  }
              );
                //base.HandleUnauthorizedRequest(filterContext);
            }
            else
            {
                filterContext.Result = new RedirectToRouteResult(
                new RouteValueDictionary {
                  { "action", "Login" },
                  { "controller", "Account" },
                  { "area", "" },
                  { "returnUrl", HttpContext.Current.Request.Url }
                  }
              );
            }
        }
    }

How to use this

Since you installed a new OS you probably don't have any more of your private and public keys that you used to sign your app in to XCode before. You need to regenerate those keys on your machine by revoking your previous certificate and asking for a new one on the iOS development portal. As part of the process you will be asked to generate a Certificate Signing Request which is where you seem to have a problem.

You will find all you need there which consists of (from the official doc):

1.Open Keychain Access on your Mac (located in Applications/Utilities).

2.Open Preferences and click Certificates. Make sure both Online Certificate Status Protocol and Certificate Revocation List are set to Off.

3.Choose Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority.

Note: If you have a private key selected when you do this, the CSR won’t be accepted. Make sure no private key is selected. Enter your user email address and common name. Use the same address and name as you used to register in the iOS Developer Program. No CA Email Address is required.

4.Select the options “Saved to disk” and “Let me specify key pair information” and click Continue.

5.Specify a filename and click Save. (make sure to replace .certSigningRequest with .csr)

For the Key Size choose 2048 bits and for Algorithm choose RSA. Click Continue and the Certificate Assistant creates a CSR and saves the file to your specified location.

This might be a little better:

}

I did a test finding a case-insensitive match of a string. I have a Vector of 150,000 objects all with a String as one field and wanted to find the subset which matched a string. I tried three methods:

1. Convert all to lower case

   for (SongInformation song: songs) {
       if (song.artist.toLowerCase().indexOf(pattern.toLowercase() > -1) {
               ...
       }
   }
   

2. Use the String matches() method

   for (SongInformation song: songs) {
       if (song.artist.matches("(?i).*" + pattern + ".*")) {
       ...
       }
   }
   

3. Use regular expressions

   Pattern p = Pattern.compile(pattern, Pattern.CASE_INSENSITIVE);
   Matcher m = p.matcher("");
   for (SongInformation song: songs) {
       m.reset(song.artist);
       if (m.find()) {
       ...
       }
   }
   

Timing results are:

• No attempted match: 20 msecs

• To lower match: 182 msecs

• String matches: 278 msecs

• Regular expression: 65 msecs

The regular expression looks to be the fastest for this use case.

Using map and lambda function can produce a list of hex values, which can be printed (or used for other purposes)

>>> s = 'Hello 1 2 3 \x01\x02\x03 :)'

>>> map(lambda c: hex(ord(c)), s)
['0x48', '0x65', '0x6c', '0x6c', '0x6f', '0x20', '0x31', '0x20', '0x32', '0x20', '0x33', '0x20', '0x1', '0x2', '0x3', '0x20', '0x3a', '0x29']

In layman's term, char is a letter, while String is a collection of letter (or a word). The distinction of ' and " is important, as 'Test' is illegal in Java.

char is a primitive type, String is a class

You could also just use regular expressions to accomplish a slightly simpler job if this is enough for you (e.g. as seen in [1]).

They are build in into javascript so you can use them without any libraries.

function isValidDate(dateString) {
  var regEx = /^\d{4}-\d{2}-\d{2}$/;
  return dateString.match(regEx) != null;
}

would be a function to check if the given string is four numbers - two numbers - two numbers (almost yyyy-mm-dd). But you can do even more with more complex expressions, e.g. check [2].

If you accept itertools but not numpy, here is an adaptation of rwh_primes2 for Python 3 that runs about twice as fast on my machine. The only substantial change is using a bytearray instead of a list for the boolean, and using compress instead of a list comprehension to build the final list. (I'd add this as a comment like moarningsun if I were able.)

import itertools
izip = itertools.zip_longest
chain = itertools.chain.from_iterable
compress = itertools.compress
def rwh_primes2_python3(n):
    """ Input n>=6, Returns a list of primes, 2 <= p < n """
    zero = bytearray([False])
    size = n//3 + (n % 6 == 2)
    sieve = bytearray([True]) * size
    sieve[0] = False
    for i in range(int(n**0.5)//3+1):
      if sieve[i]:
        k=3*i+1|1
        start = (k*k+4*k-2*k*(i&1))//3
        sieve[(k*k)//3::2*k]=zero*((size - (k*k)//3 - 1) // (2 * k) + 1)
        sieve[  start ::2*k]=zero*((size -   start  - 1) // (2 * k) + 1)
    ans = [2,3]
    poss = chain(izip(*[range(i, n, 6) for i in (1,5)]))
    ans.extend(compress(poss, sieve))
    return ans

This answer to a similar question describes how to extend the properties plugin so it can use a remote descriptor for the properties file. The descriptor is basically a jar artifact containing a properties file (the properties file is included under src/main/resources).

The descriptor is added as a dependency to the extended properties plugin so it is on the plugin's classpath. The plugin will search the classpath for the properties file, read the file''s contents into a Properties instance, and apply those properties to the project's configuration so they can be used elsewhere.

I found an easier way to get UTC in Swift4. Put this code in playground

let date = Date() 
*//"Mar 15, 2018 at 4:01 PM"*

let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd HH:mm:ss ZZZ"
dateFormatter.timeZone = TimeZone(secondsFromGMT: 0)

let newDate = dateFormatter.string(from: date) 
*//"2018-03-15 21:05:04 +0000"*

If you want a cryptographically strong random number generator (also thread safe) without using a third party API, you can use SecureRandom.

Java 6 & 7:

SecureRandom random = new SecureRandom();
byte[] bytes = new byte[20];
random.nextBytes(bytes);

Java 8 (even more secure):

byte[] bytes = new byte[20];
SecureRandom.getInstanceStrong().nextBytes(bytes);

a = 10 * [0]

gives you an array of length 10, filled with zeroes.

Here's how to do this with java.nio operations:

public static void copyFile(File sourceFile, File destFile) throws IOException {
    if(!destFile.exists()) {
        destFile.createNewFile();
    }

    FileChannel source = null;
    FileChannel destination = null;
    try {
        source = new FileInputStream(sourceFile).getChannel();
        destination = new FileOutputStream(destFile).getChannel();

        // previous code: destination.transferFrom(source, 0, source.size());
        // to avoid infinite loops, should be:
        long count = 0;
        long size = source.size();              
        while((count += destination.transferFrom(source, count, size-count))<size);
    }
    finally {
        if(source != null) {
            source.close();
        }
        if(destination != null) {
            destination.close();
        }
    }
}

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

If you are using java technology(Servlet/JSP) for making web application you will probably use Apache Tomcat. However, if you are using other technologies like Perl, PHP or ruby, its better(easier) to use Apache HTTP Server.

cp1250 is used extensively in Microsoft Office documents, including Word and Excel 2003.

http://en.wikipedia.org/wiki/Windows-1250

A simple way to confirm this would be to:

1. Create a spreadsheet with higher order characters, e.g. "Veszprém" in one of the cells;
2. Use your favourite scripting language to parse and decode the spreadsheet;
3. Look at what your script produces when you print out the decoded data.

Example perl script:

#!perl

use strict;

use Spreadsheet::ParseExcel::Simple;
use Encode qw( decode );

my $file    = "my_spreadsheet.xls";

my $xls     = Spreadsheet::ParseExcel::Simple->read( $file );
my $sheet   = [ $xls->sheets ]->[0];

while ($sheet->has_data) {

    my @data = $sheet->next_row;

    for my $datum ( @data ) {
        print decode( 'cp1250', $datum );
    }

}

Here is another, very manual solution. You can define the size of the axis and paddings are considered accordingly (including legend and tickmarks). Hope it is of use to somebody.

Example (axes size are the same!):

For multiple shell commands, I ignores the failures by adding:

set +e commands true

This is more of a stopgap 'quick and dirty' solution similar to the one Matthew Fox suggests, this time using JavaScript.

In JavaScript you can just offset the lat and long of all of your locations by adding a small random offset to both e.g.

myLocation[i].Latitude+ = (Math.random() / 25000)

(I found that dividing by 25000 gives enough separation but doesn't move the marker significantly from the exact location e.g. a specific address)

This makes a reasonably good job of offsetting them from one another, but only after you've zoomed in closely. When zoomed out, it still won't be clear that there are multiple options for the location.

rather than extension methods, just try a couple of static methods

public static class Utility
{
    public static string GetDescriptionFromEnumValue(Enum value)
    {
        DescriptionAttribute attribute = value.GetType()
            .GetField(value.ToString())
            .GetCustomAttributes(typeof (DescriptionAttribute), false)
            .SingleOrDefault() as DescriptionAttribute;
        return attribute == null ? value.ToString() : attribute.Description;
    }

    public static T GetEnumValueFromDescription<T>(string description)
    {
        var type = typeof(T);
        if (!type.IsEnum)
            throw new ArgumentException();
        FieldInfo[] fields = type.GetFields();
        var field = fields
                        .SelectMany(f => f.GetCustomAttributes(
                            typeof(DescriptionAttribute), false), (
                                f, a) => new { Field = f, Att = a })
                        .Where(a => ((DescriptionAttribute)a.Att)
                            .Description == description).SingleOrDefault();
        return field == null ? default(T) : (T)field.Field.GetRawConstantValue();
    }
}

and use here

var result1 = Utility.GetDescriptionFromEnumValue(
    Animal.GiantPanda);
var result2 = Utility.GetEnumValueFromDescription<Animal>(
    "Lesser Spotted Anteater");

There are several related solutions available on the internet, but it all depends on the configuration of the machine and the firewall rules.

For me below solution is worked:

• Disabled the VMware Network Adapter VMNet8
• Removed the network from the VM
• Enabled the VMware Network Adapter VMNet8
• Re-added the Network to VM, and set it to NAT
• Restarted the machine

You've gotten some answers, and most of them are correct, but miss what (I think) is probably the point here.

My guess is that you have a makefile you're trying to use to create an executable. In case you're not familiar with them, makefiles list dependencies between files. For a really simple case, it might have something like:

myprogram.exe: myprogram.o
    $(CC) -o myprogram.exe myprogram.o

myprogram.o: myprogram.cpp
    $(CC) -c myprogram.cpp

The first line says that myprogram.exe depends on myprogram.o. The second line tells how to create myprogram.exe from myprogram.o. The third and fourth lines say myprogram.o depends on myprogram.cpp, and how to create myprogram.o from myprogram.cpp` respectively.

My guess is that in your case, you have a makefile like the one above that was created for gcc. The problem you're running into is that you're using it with MS VC instead of gcc. As it happens, MS VC uses ".obj" as the extension for its object files instead of ".o".

That means when make (or its equivalent built into the IDE in your case) tries to build the program, it looks at those lines to try to figure out how to build myprogram.exe. To do that, it sees that it needs to build myprogram.o, so it looks for the rule that tells it how to build myprogram.o. That says it should compile the .cpp file, so it does that.

Then things break down -- the VC++ compiler produces myprogram.obj instead of myprogram.o as the object file, so when it tries to go to the next step to produce myprogram.exe from myprogram.o, it finds that its attempt at creating myprogram.o simply failed. It did what the rule said to do, but that didn't produce myprogram.o as promised. It doesn't know what to do, so it quits and give you an error message.

The cure for that specific problem is probably pretty simple: edit the make file so all the object files have an extension of .obj instead of .o. There's room for a lot of question whether that will fix everything though -- that may be all you need, or it may simply lead to other (probably more difficult) problems.

Building on lonesomeday's example (upvote that answer not this one), I ran into this output:

undefined NaN, NaN

var datetime = '1324339200000'; //LOOK HERE_x000D_
_x000D_
function prettyDate(date) {_x000D_
  var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',_x000D_
                'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];_x000D_
_x000D_
  return months[date.getUTCMonth()] + ' ' + date.getUTCDate() + ', ' + date.getUTCFullYear();_x000D_
}_x000D_
_x000D_
console.log(prettyDate(new Date(datetime))); //AND HERE

The cause was using a string as input. To fix it, prefix the string with a plus sign:

prettyDate(new Date(+datetime));

var datetime = '1324339200000';_x000D_
_x000D_
function prettyDate(date) {_x000D_
  var months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun',_x000D_

  return months[date.getUTCMonth()] + ' ' + date.getUTCDate() + ', ' + date.getUTCFullYear();_x000D_
}_x000D_

console.log(prettyDate(new Date(+datetime))); //HERE

console.log(prettyDate(new Date(+datetime)));

I had a similar problem on Internet Explorer, and got the same error number. The culprit was an HTML comment. I know it sounds unbelievable, so here is the story.

I saw a series of 6 articles on the Internet. I liked them, so I decided to download the 6 Web-Pages and store them on my Hard Drive. At the top of each page, was a couple of HTML <a> Tags, that would allow you to go to the next article or the previous article. So I changed the href attribute to point to the next folder on my Hard Drive, instead of the next URL on the Internet.

After all of the links had been re-directed, the Browser refused to display any of the Web-Pages when I clicked on the Links. The message in the Console was the Error Number that was mentioned at the top of this page.

However, the real problem was a Comment. Whenever you download a Web-Page using Google Chrome, the Chrome Browser inserts a Comment at the very top of the page that includes the URL of the location that you got the Web-Page from. After I removed the Comment at the top of each one of the 6 Pages, all of the Links worked fine ( although I continued to get the same Error Message in the Console. )

What is the difference between them?

Image: the generic Linux kernel binary image file.

zImage: a compressed version of the Linux kernel image that is self-extracting.

uImage: an image file that has a U-Boot wrapper (installed by the mkimage utility) that includes the OS type and loader information.
A very common practice (e.g. the typical Linux kernel Makefile) is to use a zImage file. Since a zImage file is self-extracting (i.e. needs no external decompressors), the wrapper would indicate that this kernel is "not compressed" even though it actually is.

Note that the author/maintainer of U-Boot considers the (widespread) use of using a zImage inside a uImage questionable:

Actually it's pretty stupid to use a zImage inside an uImage. It is much better to use normal (uncompressed) kernel image, compress it using just gzip, and use this as poayload for mkimage. This way U-Boot does the uncompresiong instead of including yet another uncompressor with each kernel image.

(quoted from https://lists.yoctoproject.org/pipermail/yocto/2013-October/016778.html)

Which type of kernel image do I have to use?

You could choose whatever you want to program for.
For economy of storage, you should probably chose a compressed image over the uncompressed one.
Beware that executing the kernel (presumably the Linux kernel) involves more than just loading the kernel image into memory. Depending on the architecture (e.g. ARM) and the Linux kernel version (e.g. with or without DTB), there are registers and memory buffers that may have to be prepared for the kernel. In one instance there was also hardware initialization that U-Boot performed that had to be replicated.

ADDENDUM

I know that u-boot needs a kernel in uImage format.

That is accurate for all versions of U-Boot which only have the bootm command.
But more recent versions of U-Boot could also have the bootz command that can boot a zImage.

Just declare? You don't have to. Just make sure variable exists:

$d = array();

Arrays are resized dynamically, and attempt to write anything to non-exsistant element creates it (and creates entire array if needed)

$d[1][2] = 3;

This is valid for any number of dimensions without prior declarations.

An example of an antipattern might be to use the with inside a loop when it would be more efficient to have the with outside the loop

for example

for row in lines:
    with open("outfile","a") as f:
        f.write(row)

vs

with open("outfile","a") as f:
    for row in lines:
        f.write(row)

The first way is opening and closing the file for each row which may cause performance problems compared to the second way with opens and closes the file just once.

if sum of column is 0 then display empty

select if(sum(column)>0,sum(column),'')
from table 

If anyone else is using fetch from the "Using Fetch" documentation on Web API's in Mozilla: (This is really useful: https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API/Using_Fetch)

  fetch(api_url + '/database', {
    method: 'POST', // or 'PUT'
    headers: {
     'Content-Type': 'application/json'
    },
    body: qrdata //notice that it is not qr but qrdata
  })
  .then((response) => response.json())
  .then((data) => {
    console.log('Success:', data);
  })  
  .catch((error) => {
  console.error('Error:', error);  });

This was inside the function:

async function postQRData(qr) {

  let qrdata = qr; //this was added to fix it!
  //then fetch was here
}

I was passing into my function qr what I believed to be an object because qr looked like this: {"name": "Jade", "lname": "Bet", "pet":"cat"} but I kept getting syntax errors. When I assigned it to something else: let qrdata = qr; it worked.

Suppose for example your date is coming like this & you need to install momentjs for advance date features.

let cmpDate = Thu Aug 27 2020 00:00:00 GMT+0530 (India Standard Time)

    let format = "MM/DD/YYYY";
    let startDate: any = moment().format(format);
    let endDate: any = moment().add(30, "days").format(format);
    let compareDate: any = moment(cmpDate).format(format);
    var startDate1 = startDate.split("/");
    var startDate2 = endDate.split("/");
    var compareDate1 = compareDate.split("/");

    var fromDate = new Date(startDate1[2], parseInt(startDate1[1]) - 1, startDate1[0]);
    var toDate = new Date(startDate2[2], parseInt(startDate2[1]) - 1, startDate2[0]);
    var checkDate = new Date(compareDate1[2], parseInt(compareDate1[1]) - 1, compareDate1[0]);

    if (checkDate > fromDate && checkDate < toDate) {
      ... condition works between current date to next 30 days
    }

If you know there are three li's in the list you're looking at, for example, you could do this:

li + li + li { /* Selects third to last li */
}

In IE6 you can use expressions:

li {
    color: expression(this.previousSibling ? 'red' : 'green'); /* 'green' if last child */
}

I would recommend using a specialized class or Javascript (not IE6 expressions), though, until the :last-child selector gets better support.

the "\xe1" represents just one byte. "\x" tells you that "e1" is in hexadecimal. When you write

Capit\xc3\xa1n

into your file you have "\xc3" in it. Those are 4 bytes and in your code you read them all. You can see this when you display them:

>>> open('f2').read()
'Capit\\xc3\\xa1n\n'

You can see that the backslash is escaped by a backslash. So you have four bytes in your string: "\", "x", "c" and "3".

Edit:

As others pointed out in their answers you should just enter the characters in the editor and your editor should then handle the conversion to UTF-8 and save it.

If you actually have a string in this format you can use the string_escape codec to decode it into a normal string:

In [15]: print 'Capit\\xc3\\xa1n\n'.decode('string_escape')
Capitán

The result is a string that is encoded in UTF-8 where the accented character is represented by the two bytes that were written \\xc3\\xa1 in the original string. If you want to have a unicode string you have to decode again with UTF-8.

To your edit: you don't have UTF-8 in your file. To actually see how it would look like:

s = u'Capit\xe1n\n'
sutf8 = s.encode('UTF-8')
open('utf-8.out', 'w').write(sutf8)

Compare the content of the file utf-8.out to the content of the file you saved with your editor.

@commonpike's answer is "the right one", but as he goes on to comment...

most browsers nowadays just support Object.keys()

Yeah.. Object.keys() is WAY better.

But what's even better? Duh, it's it in coffeescript!

sortedKeys = (x) -> Object.keys(x).sort (a,b) -> x[a] - x[b]

sortedKeys
  'a' :  1
  'b' :  3
  'c' :  4
  'd' : -1

[ 'd', 'a', 'b', 'c' ]

Short definition:

grep: search for specific terms in a file

#usage
$ grep This file.txt
Every line containing "This"
Every line containing "This"
Every line containing "This"
Every line containing "This"

$ cat file.txt
Every line containing "This"
Every line containing "This"
Every line containing "That"
Every line containing "This"
Every line containing "This"

Now awk and sed are completly different than grep. awk and sed are text processors. Not only do they have the ability to find what you are looking for in text, they have the ability to remove, add and modify the text as well (and much more).

awk is mostly used for data extraction and reporting. sed is a stream editor
Each one of them has its own functionality and specialties.

Example
Sed

$ sed -i 's/cat/dog/' file.txt
# this will replace any occurrence of the characters 'cat' by 'dog'

Awk

$ awk '{print $2}' file.txt
# this will print the second column of file.txt

Basic awk usage:
Compute sum/average/max/min/etc. what ever you may need.

$ cat file.txt
A 10
B 20
C 60
$ awk 'BEGIN {sum=0; count=0; OFS="\t"} {sum+=$2; count++} END {print "Average:", sum/count}' file.txt
Average:    30

I recommend that you read this book: Sed & Awk: 2nd Ed.

It will help you become a proficient sed/awk user on any unix-like environment.

A simple example without classes:

from tkinter import *    
master = Tk()

# Create this method before you create the entry
def return_entry(en):
    """Gets and prints the content of the entry"""
    content = entry.get()
    print(content)  

Label(master, text="Input: ").grid(row=0, sticky=W)

entry = Entry(master)
entry.grid(row=0, column=1)

# Connect the entry with the return button
entry.bind('<Return>', return_entry) 

mainloop()

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

The content of the table/tables in PostgreSQL database can be deleted in several ways.

Deleting table content using sql:

Deleting content of one table:

TRUNCATE table_name;
DELETE FROM table_name;

Deleting content of all named tables:

TRUNCATE table_a, table_b, …, table_z;

Deleting content of named tables and tables that reference to them (I will explain it in more details later in this answer):

TRUNCATE table_a, table_b CASCADE;

Deleting table content using pgAdmin:

Deleting content of one table:

Right click on the table -> Truncate

Deleting content of table and tables that reference to it:

Right click on the table -> Truncate Cascaded

Difference between delete and truncate:

From the documentation:

DELETE deletes rows that satisfy the WHERE clause from the specified table. If the WHERE clause is absent, the effect is to delete all rows in the table. http://www.postgresql.org/docs/9.3/static/sql-delete.html

TRUNCATE is a PostgreSQL extension that provides a faster mechanism to remove all rows from a table. TRUNCATE quickly removes all rows from a set of tables. It has the same effect as an unqualified DELETE on each table, but since it does not actually scan the tables it is faster. Furthermore, it reclaims disk space immediately, rather than requiring a subsequent VACUUM operation. This is most useful on large tables. http://www.postgresql.org/docs/9.1/static/sql-truncate.html

Working with table that is referenced from other table:

When you have database that has more than one table the tables have probably relationship. As an example there are three tables:

create table customers (
customer_id int not null,
name varchar(20),
surname varchar(30),
constraint pk_customer primary key (customer_id)
);

create table orders (
order_id int not null,
number int not null,
customer_id int not null,
constraint pk_order primary key (order_id),
constraint fk_customer foreign key (customer_id) references customers(customer_id)
);

create table loyalty_cards (
card_id int not null,
card_number varchar(10) not null,
customer_id int not null,
constraint pk_card primary key (card_id),
constraint fk_customer foreign key (customer_id) references customers(customer_id)
);

And some prepared data for these tables:

insert into customers values (1, 'John', 'Smith');

insert into orders values 
(10, 1000, 1),
(11, 1009, 1),
(12, 1010, 1);        

insert into loyalty_cards values (100, 'A123456789', 1);

Table orders references table customers and table loyalty_cards references table customers. When you try to TRUNCATE / DELETE FROM the table that is referenced by other table/s (the other table/s has foreign key constraint to the named table) you get an error. To delete content from all three tables you have to name all these tables (the order is not important)

TRUNCATE customers, loyalty_cards, orders;

or just the table that is referenced with CASCADE key word (you can name more tables than just one)

TRUNCATE customers CASCADE;

The same applies for pgAdmin. Right click on customers table and choose Truncate Cascaded.

I'd factor out the prepared statement handling to at least a method. In this case, because there are no results it is fairly simple (and assuming that the connection is an instance variable that doesn't change):

private PreparedStatement updateSales;
public void updateSales(int sales, String cof_name) throws SQLException {
    if (updateSales == null) {
        updateSales = con.prepareStatement(
            "UPDATE COFFEES SET SALES = ? WHERE COF_NAME LIKE ?");
    }
    updateSales.setInt(1, sales);
    updateSales.setString(2, cof_name);
    updateSales.executeUpdate();
}

At that point, it is then just a matter of calling:

updateSales(75, "Colombian");

Which is pretty simple to integrate with other things, yes? And if you call the method many times, the update will only be constructed once and that will make things much faster. Well, assuming you don't do crazy things like doing each update in its own transaction...

Note that the types are fixed. This is because for any particular query/update, they should be fixed so as to allow the database to do its job efficiently. If you're just pulling arbitrary strings from a CSV file, pass them in as strings. There's also no locking; far better to keep individual connections to being used from a single thread instead.

Here is a workaround using a flag:

//outside your event or method, but inside your class
private bool IsExecuted = false;

private async Task MethodA()
{

//Do Stuff Here

IsExecuted = true;
}

.
.
.

//Inside your event or method

{
await MethodA();

while (!isExecuted) Thread.Sleep(200); // <-------

await MethodB();
}

A version using MSHTA and javascript. Change %jsfunc% to whateve jscript function you want to call

@echo off
::Invoke a javascript function using mhta

set jsfunc=new Date().getDay()
set dialog="about:<script>resizeTo(0,0);new ActiveXObject('Scripting.FileSystemObject').
set dialog=%dialog%GetStandardStream(1).WriteLine(%jsfunc%);close();</script>"

for /f "tokens=* delims=" %%p in ('mshta.exe %dialog%') do set ndow=%%p

::get dow string from array of strings  
for /f "tokens=%ndow%"  %%d in ("Mon Tue Wed Thu Fri Sat Sun") do set dow=%%d 

echo dow is : %ndow%  %dow%
pause

        <android.support.design.widget.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <EditText
                android:id="@+id/name"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:hint="Name"
                android:textColor="@color/black"
                android:textColorHint="@color/grey"/>
        </android.support.design.widget.TextInputLayout>

Use textColorHint to set the color that you want as the Hint color for the EditText. The thing is that Hint in the EditText disappears not when you type something, but immediately when the EditText gets focus (with a cool animation). You will notice this clearly when you switch focus away and to the EditText.

The method used in the accepted answer drop attributes when encountering child elements with only a text node. For example:

$xml = '<container><element attribute="123">abcd</element></container>';
print_r(json_decode(json_encode(simplexml_load_string($xml, "SimpleXMLElement", LIBXML_NOCDATA)),1));

Array
(
    [element] => abcd
)

My solution (and I wish I could give credit here because I'm sure I adapted this from something):

function XMLtoArray($xml) {
    $previous_value = libxml_use_internal_errors(true);
    $dom = new DOMDocument('1.0', 'UTF-8');
    $dom->preserveWhiteSpace = false; 
    $dom->loadXml($xml);
    libxml_use_internal_errors($previous_value);
    if (libxml_get_errors()) {
        return [];
    }
    return DOMtoArray($dom);
}

function DOMtoArray($root) {
    $result = array();

    if ($root->hasAttributes()) {
        $attrs = $root->attributes;
        foreach ($attrs as $attr) {
            $result['@attributes'][$attr->name] = $attr->value;
        }
    }

    if ($root->hasChildNodes()) {
        $children = $root->childNodes;
        if ($children->length == 1) {
            $child = $children->item(0);
            if (in_array($child->nodeType,[XML_TEXT_NODE,XML_CDATA_SECTION_NODE])) {
                $result['_value'] = $child->nodeValue;
                return count($result) == 1
                    ? $result['_value']
                    : $result;
            }

        }
        $groups = array();

Creating an isolate scope is undesirable. I would avoid using the scope attribute and do something like this. scope:true gives you a new child scope but not isolate. Then use parse to point a local scope variable to the same object the user has supplied to the ngModel attribute.

app.directive('myDir', ['$parse', function ($parse) {
    return {
        restrict: 'EA',
        scope: true,
        link: function (scope, elem, attrs) {
            if(!attrs.ngModel) {return;}
            var model = $parse(attrs.ngModel);
            scope.model = model(scope);
        }
    };
}]);

From the dplyr package you can also use the mutate_all() function in combination with toupper(). This will affect both character and factor classes.

library(dplyr)
df <- mutate_all(df, funs=toupper)

The other two answers are correct. When you include spaces in your CSS selectors you're targeting child elements so:

.form-group .required {
    styles
}

Is targeting an element with the class of "required" that is inside an element with the class of "form-group".

Without the space it's targeting an element that has both classes. 'required' and 'form-group'

Use "This is' it".replace("'", "\\'")

thanks S Doerin:

"Just for completion. This error might be as well the case if you have a foreign key with VARCHAR(..) and the charset of the referenced table is different from the table referencing it. e.g. VARCHAR(50) in a Latin1 Table is different than the VARCHAR(50) in a UTF8 Table."

i solved this problem, changing the type of characters of the table. the creation have latin1 and the correct is utf8.

add the next line. DEFAULT CHARACTER SET = utf8;

"Thousands" is not a large number. A few thousand paragraph-length strings are on the order of a couple of megabytes in size. If all you want to do is access these serially, use an immutable singly-linked List.

Yes numpy has a size function, and shape and size are not quite the same.

Input

import numpy as np
data = [[1, 2, 3, 4], [5, 6, 7, 8]]
arrData = np.array(data)

print(data)
print(arrData.size)
print(arrData.shape)

Output

[[1, 2, 3, 4], [5, 6, 7, 8]]

8 # size

(2, 4) # shape

in devices which has Android 4.3 and above you should follow these steps:

How to enable Developer Options:

Launch Settings menu.
Find the open the ‘About Device’ menu.
Scroll down to ‘Build Number’.
Next, tap on the ‘build number’ section seven times.
After the seventh tap you will be told that you are now a developer.
Go back to Settings menu and the Developer Options menu will now be displayed.

In order to enable the USB Debugging you will simply need to open Developer Options, scroll down and tick the box that says ‘USB Debugging’. That’s it.

Here's the best answer, and the easiest! Put an extra password field in front of your input field and set the display:none , so that when the browser fills it in, it does it in an input that you don't care about.

Change this:

<input type="password" name="password" size="25" class="input" id="password" value="">

to this:

<input type="password" style="display:none;">
<input type="password" name="password" size="25" class="input" id="password" value="">

def p1( ):
    print("in p1")

def p2():

For the record, jQuery has an is() function for this:

a.is(b)

Note that a is already a jQuery instance.

Errors and exceptions in PowerShell are structured objects. The error message you see printed on the console is actually a formatted message with information from several elements of the error/exception object. You can (re-)construct it yourself like this:

$formatstring = "{0} : {1}`n{2}`n" +
                "    + CategoryInfo          : {3}`n" +
                "    + FullyQualifiedErrorId : {4}`n"
$fields = $_.InvocationInfo.MyCommand.Name,
          $_.ErrorDetails.Message,
          $_.InvocationInfo.PositionMessage,
          $_.CategoryInfo.ToString(),
          $_.FullyQualifiedErrorId

$formatstring -f $fields

If you just want the error message displayed in your catch block you can simply echo the current object variable (which holds the error at that point):

try {
  ...
} catch {
  $_
}

If you need colored output use Write-Host with a formatted string as described above:

try {
  ...
} catch {
  ...
  Write-Host -Foreground Red -Background Black ($formatstring -f $fields)
}

With that said, usually you don't want to just display the error message as-is in an exception handler (otherwise the -ErrorAction Stop would be pointless). The structured error/exception objects provide you with additional information that you can use for better error control. For instance you have $_.Exception.HResult with the actual error number. $_.ScriptStackTrace and $_.Exception.StackTrace, so you can display stacktraces when debugging. $_.Exception.InnerException gives you access to nested exceptions that often contain additional information about the error (top level PowerShell errors can be somewhat generic). You can unroll these nested exceptions with something like this:

$e = $_.Exception
$msg = $e.Message
while ($e.InnerException) {
  $e = $e.InnerException
  $msg += "`n" + $e.Message
}
$msg

In your case the information you want to extract seems to be in $_.ErrorDetails.Message. It's not quite clear to me if you have an object or a JSON string there, but you should be able to get information about the types and values of the members of $_.ErrorDetails by running

$_.ErrorDetails | Get-Member
$_.ErrorDetails | Format-List *

If $_.ErrorDetails.Message is an object you should be able to obtain the message string like this:

$_.ErrorDetails.Message.message

otherwise you need to convert the JSON string to an object first:

$_.ErrorDetails.Message | ConvertFrom-Json | Select-Object -Expand message

Depending what kind of error you're handling, exceptions of particular types might also include more specific information about the problem at hand. In your case for instance you have a WebException which in addition to the error message ($_.Exception.Message) contains the actual response from the server:

PS C:\> $e.Exception | Get-Member

   TypeName: System.Net.WebException

Name             MemberType Definition

Status           Property   System.Net.WebExceptionStatus Status {get;}
TargetSite       Property   System.Reflection.MethodBase TargetSite {get;}

which provides you with information like this:

PS C:\> $e.Exception.Response

IsMutuallyAuthenticated : False
Cookies                 : {}

Since not all exceptions have the exact same set of properties you may want to use specific handlers for particular exceptions:

try {
  ...
} catch [System.ArgumentException] {
  # handle argument exceptions
} catch [System.Net.WebException] {
  # handle web exceptions
} catch {
  # handle all other exceptions
}

If you have operations that need to be done regardless of whether an error occured or not (cleanup tasks like closing a socket or a database connection) you can put them in a finally block after the exception handling:

try {
  ...
} catch {
  ...
} finally {
  # cleanup operations go here
}

From what I've learned with Alex Cowan in the course Continuous Delivery & DevOps, CI and CD is part of a product pipeline that consists in the time it goes from an Observations to a Released Product.

From Observations to Designs the goal is to get high quality testable ideas. This part of the process is considered Continuous Design.

What happens after, when we go from the Code onwards, it's considered a Continuous Delivery capability whose aim is to execute the ideas and release to the customer very fast (you can read Jez Humble's book Continuous Delivery: Reliable Software Releases through Build, Test, and Deployment Automation for more details). The following pipeline explains which steps Continuous Integration (CI) and Continuous Delivery (CD) consist of.

Continuous Integration, as Mattias Petter Johansson explains,

is when a software team has habit of doing multiple merges per day and they have an automated verification system in place to check those merges for problems.

(you can watch the following two videos for a more pratical overview using CircleCI - Getting started with CircleCI - Continuous Integration P2 and Running CircleCI on Pull Request).

One can specify the CI/CD pipeline as following, that goes from New Code to a released Product.

The first three steps have to do with Tests, extending the boundary of what's being tested.

Continuous Deployment, on the other hand, is to handle the Deployment automatically. So, any code commit that passes the automated testing phase is automatically released into the production.

Note: This isn't necessarily what your pipelines should look like, yet they can serve as reference.

Just use the length property of a JavaScript array like so:

$scope.names.length

Also, I don't see a starting <script> tag in your code.

If you want the length inside your view, do it like so:

{{ names.length }}

Usually I will just use the undocumented proc sp_MSForEachTable

-- disable referential integrity
EXEC sp_MSForEachTable 'ALTER TABLE ? NOCHECK CONSTRAINT ALL' 
GO 

EXEC sp_MSForEachTable 'TRUNCATE TABLE ?' 
GO 

-- enable referential integrity again 
EXEC sp_MSForEachTable 'ALTER TABLE ? CHECK CONSTRAINT ALL' 
GO

First check whether the java classes are compiled or not in your [PROJECT_NAME]\target\classes directory.

If not you have some compilation errors in your java classes.

I've implemented cross-browser compatible page to test browser's refresh behavior (here is the source code) and get results similar to @some, but for modern browsers:

You should use

 SSLContext.getInstance("TLSv1.2"); 

for specific protocol version.

The second exception occured because default socketFactory used fallback SSLv3 protocol for failures.

You can use NoSSLFactory from main answer here for its suppression How to disable SSLv3 in android for HttpsUrlConnection?

Also you should init SSLContext with all your certificates(client and trusted ones if you need them)

But all of that is useless without using

ProviderInstaller.installIfNeeded(getContext())

Here is more information with proper usage scenario https://developer.android.com/training/articles/security-gms-provider.html

Hope it helps.

They are taking a 'shotgun' approach to referencing the font. The browser will attempt to match each font name with any installed fonts on the user's machine (in the order they have been listed).

In your example "HelveticaNeue-Light" will be tried first, if this font variant is unavailable the browser will try "Helvetica Neue Light" and finally "Helvetica Neue".

As far as I'm aware "Helvetica Neue" isn't considered a 'web safe font', which means you won't be able to rely on it being installed for your entire user base. It is quite common to define "serif" or "sans-serif" as a final default position.

In order to use fonts which aren't 'web safe' you'll need to use a technique known as font embedding. Embedded fonts do not need to be installed on a user's computer, instead they are downloaded as part of the page. Be aware this increases the overall payload (just like an image does) and can have an impact on page load times.

A great resource for free fonts with open-source licenses is Google Fonts. (You should still check individual licenses before using them.) Each font has a download link with instructions on how to embed them in your website.

One case which is prevalent in duplicates is the requirement to use quotes for external processes. A workaround for that is to not use a shell, which removes the requirement for one level of quoting.

os.system("""awk '/foo/ { print "bar" }' %""" % filename)

can usefully be replaced with

subprocess.call(['awk', '/foo/ { print "bar" }', filename])

(which also fixes the bug that shell metacharacters in filename would need to be escaped from the shell, which the original code failed to do; but without a shell, no need for that).

Of course, in the vast majority of cases, you don't want or need an external process at all.

with open(filename) as fh:
    for line in fh:
        if 'foo' in line:
            print("bar")

There is also one ugly but working way. Decompile FirebaseMessagingService.class and modify it's behavior. Then just put the class to the right package in yout app and dex use it instead of the class in the messaging lib itself. It is quite easy and working.

There is method:

private void zzo(Intent intent) {
    Bundle bundle = intent.getExtras();
    bundle.remove("android.support.content.wakelockid");
    if (zza.zzac(bundle)) {  // true if msg is notification sent from FirebaseConsole
        if (!zza.zzdc((Context)this)) { // true if app is on foreground
            zza.zzer((Context)this).zzas(bundle); // create notification
            return;
        }
        // parse notification data to allow use it in onMessageReceived whe app is on foreground
        if (FirebaseMessagingService.zzav(bundle)) {
            zzb.zzo((Context)this, intent);
        }
    }
    this.onMessageReceived(new RemoteMessage(bundle));
}

This code is from version 9.4.0, method will have different names in different version because of obfuscation.

import java.io.*;

public class Code {
  public static void main(String[] args) throws Exception {
    ProcessBuilder builder = new ProcessBuilder("ls", "-ltr");
    Process process = builder.start();

    StringBuilder out = new StringBuilder();
    try (BufferedReader reader = new BufferedReader(new InputStreamReader(process.getInputStream()))) {
        String line = null;
      while ((line = reader.readLine()) != null) {
        out.append(line);
        out.append("\n");
      }
      System.out.println(out);
    }
  }
}

Try online

private fun setImage(view: ImageView, uri: Uri) {
        val stream = contentResolver.openInputStream(uri)
        val bitmap = BitmapFactory.decodeStream(stream)
        view.setImageBitmap(bitmap)
}

curl sends POST requests with the default content type of application/x-www-form-urlencoded. If you want to send a JSON request, you will have to specify the correct content type header:

$ curl -vX POST http://server/api/v1/places.json -d @testplace.json \
--header "Content-Type: application/json"

But that will only work if the server accepts json input. The .json at the end of the url may only indicate that the output is json, it doesn't necessarily mean that it also will handle json input. The API documentation should give you a hint on whether it does or not.

The reason you get a 401 and not some other error is probably because the server can't extract the auth_token from your request.

For a recursive search:

find . -type f -name '*.log' -printf x | wc -c

wc -c will count the number of characters in the output of find, while -printf x tells find to print a single x for each result.

For a non-recursive search, do this:

find . -maxdepth 1 -type f -name '*.log' -printf x | wc -c

May be using this query you don't get any result or empty result. You need to use OR instead of AND in your query like below.

$query = mysql_query("SELECT image_id FROM list WHERE (style_id = 24 AND style_value = 'red') OR (style_id = 25 AND style_value = 'big') OR (style_id = 27 AND style_value = 'round');

Try out this query.

I know people say you shouldn't use regular expressions to parse HTML, but in this case I find it perfectly fine.

$string = '<img border="0" src="/images/image.jpg" alt="Image" width="100" height="100" />';
preg_match('/<img(.*)src(.*)=(.*)"(.*)"/U', $string, $result);
$foo = array_pop($result);

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

When I do what explains some answers:

The result is:

So, anybody can explain really really how to delete an old App ID?

My opinion is: Apple does not let you remove them. I suppose it is a way to maintain the traceability or the historical of the published.

And of course: application is no longer available in the App Store. It was available (in the past), yes.

If you're using MFC, you can use CString:

int a = 10;
CString strA;
strA.Format("%d", a);

PreparedStatement doesn't provide any good way to deal with SQL IN clause. Per http://www.javaranch.com/journal/200510/Journal200510.jsp#a2 "You can't substitute things that are meant to become part of the SQL statement. This is necessary because if the SQL itself can change, the driver can't precompile the statement. It also has the nice side effect of preventing SQL injection attacks." I ended up using following approach:

String query = "SELECT my_column FROM my_table where search_column IN ($searchColumns)";
query = query.replace("$searchColumns", "'A', 'B', 'C'");
Statement stmt = connection.createStatement();
boolean hasResults = stmt.execute(query);
do {
    if (hasResults)
        return stmt.getResultSet();

    hasResults = stmt.getMoreResults();

} while (hasResults || stmt.getUpdateCount() != -1);

How about this

for (int i = 0; i < str.length(); i++) { 
    System.out.println(str.substring(i, i + 1)); 
} 

That's a very complex question for a simple answer.

You may want to take a look at existing API frameworks, like Swagger Specification (OpenAPI), and services like apiary.io and apiblueprint.org.

Also, here's an example of the same REST API described, organized and even styled in three different ways. It may be a good start for you to learn from existing common ways.

• https://api.coinsecure.in/v1
• https://api.coinsecure.in/v1/originalUI
• https://api.coinsecure.in/v1/slateUI#!/Blockchain_Tools/v1_bitcoin_search_txid

At the very top level I think quality REST API docs require at least the following:

• a list of all your API endpoints (base/relative URLs)
• corresponding HTTP GET/POST/... method type for each endpoint
• request/response MIME-type (how to encode params and parse replies)
• a sample request/response, including HTTP headers
• type and format specified for all params, including those in the URL, body and headers
• a brief text description and important notes
• a short code snippet showing the use of the endpoint in popular web programming languages

Also there are a lot of JSON/XML-based doc frameworks which can parse your API definition or schema and generate a convenient set of docs for you. But the choice for a doc generation system depends on your project, language, development environment and many other things.

The Content hugging priority is like a Rubber band that is placed around a view. The higher the priority value, the stronger the rubber band and the more it wants to hug to its content size. The priority value can be imagined like the "strength" of the rubber band

And the Content Compression Resistance is, how much a view "resists" getting smaller The View with higher resistance priority value is the one that will resist compression.

A thing to note is that you need to send in an object for Lambda expressions and can't use an instance for a class.

Example:

public class Key
{
    public string Prop1 { get; set; }

    public string Prop2 { get; set; }
}

This will compile but will generate one key per cycle.

var groupedCycles = cycles.GroupBy(x => new Key
{ 
  Prop1 = x.Column1, 
  Prop2 = x.Column2 
})

If you wan't to name the key properties and then retreive them you can do it like this instead. This will GroupBy correctly and give you the key properties.

var groupedCycles = cycles.GroupBy(x => new 
{ 
  Prop1 = x.Column1, 
  Prop2= x.Column2 
})

foreach (var groupedCycle in groupedCycles)
{
    var key = new Key();
    key.Prop1 = groupedCycle.Key.Prop1;
    key.Prop2 = groupedCycle.Key.Prop2;
}

This is how I enhance the enum inheritance pattern with runtime check in static initializer. The BaseKind#checkEnumExtender checks that "extending" enum declares all the values of the base enum in exactly the same way so #name() and #ordinal() remain fully compatible.

There is still copy-paste involved for declaring values but the program fails fast if somebody added or modified a value in the base class without updating extending ones.

Common behavior for different enums extending each other:

public interface Kind {
  /**
   * Let's say we want some additional member.
   */
  String description() ;

  /**
   * Standard {@code Enum} method.
   */
  String name() ;

  /**
   * Standard {@code Enum} method.
   */
  int ordinal() ;
}

Base enum, with verifying method:

public enum BaseKind implements Kind {

  FIRST( "First" ),
  SECOND( "Second" ),

  ;

  private final String description ;

  public String description() {
    return description ;
  }

  private BaseKind( final String description ) {
    this.description = description ;
  }

  public static void checkEnumExtender(
      final Kind[] baseValues,
      final Kind[] extendingValues
  ) {
    if( extendingValues.length < baseValues.length ) {
      throw new IncorrectExtensionError( "Only " + extendingValues.length + " values against "
          + baseValues.length + " base values" ) ;
    }
    for( int i = 0 ; i < baseValues.length ; i ++ ) {
      final Kind baseValue = baseValues[ i ] ;
      final Kind extendingValue = extendingValues[ i ] ;
      if( baseValue.ordinal() != extendingValue.ordinal() ) {
        throw new IncorrectExtensionError( "Base ordinal " + baseValue.ordinal()
            + " doesn't match with " + extendingValue.ordinal() ) ;
      }
      if( ! baseValue.name().equals( extendingValue.name() ) ) {
        throw new IncorrectExtensionError( "Base name[ " + i + "] " + baseValue.name()
            + " doesn't match with " + extendingValue.name() ) ;
      }
      if( ! baseValue.description().equals( extendingValue.description() ) ) {
        throw new IncorrectExtensionError( "Description[ " + i + "] " + baseValue.description()
            + " doesn't match with " + extendingValue.description() ) ;
      }
    }
  }


  public static class IncorrectExtensionError extends Error {
    public IncorrectExtensionError( final String s ) {
      super( s ) ;
    }
  }

}

Extension sample:

public enum ExtendingKind implements Kind {
  FIRST( BaseKind.FIRST ),
  SECOND( BaseKind.SECOND ),
  THIRD( "Third" ),
  ;

  private final String description ;

  public String description() {
    return description ;
  }

  ExtendingKind( final BaseKind baseKind ) {
    this.description = baseKind.description() ;
  }

  ExtendingKind( final String description ) {
    this.description = description ;
  }

}

*JAVA SCRIPT TO SELECT ALL CHECK BOX *

Best Solution.. Try it

<script type="text/javascript">
        function SelectAll(Id) {
            //get reference of GridView control
            var Grid = document.getElementById("<%= GridView1.ClientID %>");
            //variable to contain the cell of the Grid
            var cell;

            if (Grid.rows.length > 0) {
                //loop starts from 1. rows[0] points to the header.
                for (i = 1; i < grid.rows.length; i++) {
                    //get the reference of first column
                    cell = grid.rows[i].cells[0];

                    //loop according to the number of childNodes in the cell
                    for (j = 0; j < cell.childNodes.length; j++) {
                        //if childNode type is CheckBox                 
                        if (cell.childNodes[j].type == "checkbox") {
                            //Assign the Status of the Select All checkbox to the cell checkbox within the Grid
                            cell.childNodes[j].checked = document.getElementById(Id).checked;
                        }
                    }
                }
            }
        }
    </script>

The one that worked for me is:

grep -e '->'

The -e means that the next argument is the pattern, and won't be interpreted as an argument.

From: http://www.linuxquestions.org/questions/programming-9/how-to-grep-for-string-769460/

Python is a dynamically typed language, which means that you cannot define the type of the variable as you do in C or C++:

type variable = value

or

type variable(value)

In Python, you use coercing if you change types, or the init functions (constructors) of the types to declare a variable of a type:

my_set = set([1,2,3])
type my_set

will give you <type 'set'> for an answer.

If you have a list, do this:

my_list = [1,2,3]
my_set = set(my_list)

Note the standard sed syntax (as in POSIX, so supported by all conforming sed implementations around (GNU, OS/X, BSD, Solaris...)):

sed '/CLIENTSCRIPT=/a\
CLIENTSCRIPT2="hello"' file

Or on one line:

sed -e '/CLIENTSCRIPT=/a\' -e 'CLIENTSCRIPT2="hello"' file

(-expressions (and the contents of -files) are joined with newlines to make up the sed script sed interprets).

The -i option for in-place editing is also a GNU extension, some other implementations (like FreeBSD's) support -i '' for that.

Alternatively, for portability, you can use perl instead:

perl -pi -e '$_ .= qq(CLIENTSCRIPT2="hello"\n) if /CLIENTSCRIPT=/' file

Or you could use ed or ex:

printf '%s\n' /CLIENTSCRIPT=/a 'CLIENTSCRIPT2="hello"' . w q | ex -s file

if using /bin/sh you can use:

if [ <condition> ] && [ <condition> ]; then
    ...
fi

if using /bin/bash you can use:

if [[ <condition> && <condition> ]]; then
    ...
fi
