Programs & Examples On #Standard deviation

Here's some pure-Python code you can use to calculate the mean and standard deviation.

All code below is based on the statistics module in Python 3.4+.

def mean(data):
    """Return the sample arithmetic mean of data."""
    n = len(data)
    if n < 1:
        raise ValueError('mean requires at least one data point')
    return sum(data)/n # in Python 2 use sum(data)/float(n)

def _ss(data):
    """Return sum of square deviations of sequence data."""
    c = mean(data)
    ss = sum((x-c)**2 for x in data)
    return ss

def stddev(data, ddof=0):
    """Calculates the population standard deviation
    by default; specify ddof=1 to compute the sample
    standard deviation."""
    n = len(data)
    if n < 2:
        raise ValueError('variance requires at least two data points')
    ss = _ss(data)
    pvar = ss/(n-ddof)
    return pvar**0.5

Note: for improved accuracy when summing floats, the statistics module uses a custom function _sum rather than the built-in sum which I've used in its place.

Now we have for example:

>>> mean([1, 2, 3])
2.0
>>> stddev([1, 2, 3]) # population standard deviation
0.816496580927726
>>> stddev([1, 2, 3], ddof=1) # sample standard deviation
0.1

You can use arrows:

arrows(x,y-sd,x,y+sd, code=3, length=0.02, angle = 90)

After displaying the first 1000 records, you can page through them by clicking on the icon beside "Fetch rows:" in the header of the result grid.

If you wish to invoke a method if some boolean is true, you can put else None to terminate the trinary.

>>> a=1
>>> print(a) if a==1 else None
1
>>> print(a) if a==2 else None
>>> a=2
>>> print(a) if a==2 else None
2
>>> print(a) if a==1 else None
>>>

No need to add any third party library. Just use below code...

class SubmitReviewVC : UIViewController, UITextViewDelegate {

@IBOutlet var txtMessage : UITextView!
var lblPlaceHolder : UILabel!

override func viewDidLoad() {
    super.viewDidLoad()

    txtMessage.delegate = self
    lblPlaceHolder = UILabel()
    lblPlaceHolder.text = "Enter message..."
    lblPlaceHolder.font = UIFont.systemFont(ofSize: txtMessage.font!.pointSize)
    lblPlaceHolder.sizeToFit()
    txtMessage.addSubview(lblPlaceHolder)
    lblPlaceHolder.frame.origin = CGPoint(x: 5, y: (txtMessage.font?.pointSize)! / 2)
    lblPlaceHolder.textColor = UIColor.lightGray
    lblPlaceHolder.isHidden = !txtMessage.text.isEmpty
}

func textViewDidChange(_ textView: UITextView) {
    lblPlaceHolder.isHidden = !textView.text.isEmpty
}

}

This code may be helpful for you.

When uncertain or in doubt, run in circles, scream and shout.

class Ourself
{
    public static string OurFileName() {
        System.Reflection.Assembly _objParentAssembly;

        if (System.Reflection.Assembly.GetEntryAssembly() == null)
            _objParentAssembly = System.Reflection.Assembly.GetCallingAssembly();
        else
            _objParentAssembly = System.Reflection.Assembly.GetEntryAssembly();

        if (_objParentAssembly.CodeBase.StartsWith("http://"))
            throw new System.IO.IOException("Deployed from URL");

        if (System.IO.File.Exists(_objParentAssembly.Location))
            return _objParentAssembly.Location;
        if (System.IO.File.Exists(System.AppDomain.CurrentDomain.BaseDirectory + System.AppDomain.CurrentDomain.FriendlyName))
            return System.AppDomain.CurrentDomain.BaseDirectory + System.AppDomain.CurrentDomain.FriendlyName;
        if (System.IO.File.Exists(System.Reflection.Assembly.GetExecutingAssembly().Location))
            return System.Reflection.Assembly.GetExecutingAssembly().Location;

        throw new System.IO.IOException("Assembly not found");
    }
}

I can't claim to have tested each option, but it doesn't do anything stupid like returning the vhost during debugging sessions.

For those who need the input file to open directly the camera, you just have to declare capture parameter to the input file, like this :

<input type="file" accept="image/*" capture>

SLaks answer is correct, but as an addendum note that the x/html specs specify that all ids must be unique within a (single) html document. Although it's not exactly what the op asked, there could be valid instances where the same id is attached to different entities across multiple pages.

Example:

(served to modern browsers) article#main-content {styled one way}
(served to legacy) div#main-content {styled another way}

Probably an antipattern though. Just leaving here as a devil's advocate point.

I had the same problem with woff-fonts, multiple subdomains had to have access. To allow subdomains I added something like this to my httpd.conf:

SetEnvIf Origin "^(.*\.example\.com)$" ORIGIN_SUB_DOMAIN=$1
<FilesMatch "\.woff$">
    Header set Access-Control-Allow-Origin "%{ORIGIN_SUB_DOMAIN}e" env=ORIGIN_SUB_DOMAIN
</FilesMatch>

For multiple domains you could just change the regex in SetEnvIf.

I modified the WW's query to provide more detailed information:

SELECT * FROM (
  SELECT
    owner, object_name, object_type, table_name, ROUND(bytes)/1024/1024 AS meg,
    tablespace_name, extents, initial_extent,
    ROUND(Sum(bytes/1024/1024) OVER (PARTITION BY table_name)) AS total_table_meg
  FROM (
    -- Tables
    SELECT owner, segment_name AS object_name, 'TABLE' AS object_type,
          segment_name AS table_name, bytes,
          tablespace_name, extents, initial_extent
    FROM   dba_segments
    WHERE  segment_type IN ('TABLE', 'TABLE PARTITION', 'TABLE SUBPARTITION')
    UNION ALL
    -- Indexes

How about running the following from command line,

Devenv.exe /ResetSettings

You could also save those settings in to a file, like so,

Devenv.exe /ResetSettings "C:\My Files\MySettings.vssettings"

The /ResetSettings switch, Restores Visual Studio default settings. Optionally resets the settings to the specified .vssettings file.

You can use SQL Management Objects to perform this. These are the same objects that Management Studio uses to execute queries. I believe Server.ConnectionContext.ExecuteNonQuery() will perform what you need.

Here is if you want to locate it next to your executable (relative from the executable)

img.Source = new BitmapImage(new Uri(AppDomain.CurrentDomain.BaseDirectory + @"\Images\image.jpg", UriKind.Absolute));

While many of the suggestions work when converting 2 -> 4 space. I ran into some issues when converting 4 -> 2.

Here's what I ended up using:

Sublime Text 3/Packages/User/to-2.sublime-macro

[
  { "args": null, "command": "select_all" },
  { "args": { "set_translate_tabs": true }, "command": "unexpand_tabs" },
  { "args": { "setting": "tab_size", "value": 1 }, "command": "set_setting" },
  { "args": { "set_translate_tabs": true }, "command": "expand_tabs" },
  { "args": { "setting": "tab_size", "value": 2 }, "command": "set_setting" }

I wrote a function wrapper called bar() for barplot() to do what you are trying to do here, since I need to do similar things frequently. The Github link to the function is here. After copying and pasting it into R, you do

bar(dv = Species, 
    factors = c(Category, Reason), 
    dataframe = Reasonstats, 
    errbar = FALSE, 
    ylim=c(0, 140))  #I increased the upper y-limit to accommodate the legend. 

The one convenience is that it will put a legend on the plot using the names of the levels in your categorical variable (e.g., "Decline" and "Improved"). If each of your levels has multiple observations, it can also plot the error bars (which does not apply here, hence errbar=FALSE

To print the content of Root store:

certutil -store Root

To output content to a file:

certutil -store Root > root_content.txt

To add certificate to Root store:

certutil -addstore -enterprise Root file.cer

In Android Studio, which, quite honestly, you should be using, change the package name by right-clicking on the package name in the project structure -> Refactor -> Rename...

It then gives the option of renaming the directory or the package. Select the package. The directory should follow suit. Type in your new package name, and click Refactor. It will change all the imports and remove redundant imports for you. You can even have it fix it for you in comments and strings, etc.

Lastly, change the package name accordingly in your AndroidManifest.xml towards the top. Otherwise you will get errors everywhere complaining about R.whatever.

Another very useful solution

First create a new package with the desired nameby right clicking on thejava folder -> new -> package.`

Then, select and drag all your classes to the new package. AndroidStudio will re-factor the package name everywhere.

After that: in your app's build.gradle add/edit applicationId with the new one. i.e. (com.a.bc in my case):

defaultConfig {
    applicationId "com.a.bc"
    minSdkVersion 13
    targetSdkVersion 19
}

Original post and more comments here

flask.Flask.run accepts additional keyword arguments (**options) that it forwards to werkzeug.serving.run_simple - two of those arguments are threaded (a boolean) and processes (which you can set to a number greater than one to have werkzeug spawn more than one process to handle requests).

threaded defaults to True as of Flask 1.0, so for the latest versions of Flask, the default development server will be able to serve multiple clients simultaneously by default. For older versions of Flask, you can explicitly pass threaded=True to enable this behaviour.

For example, you can do

if __name__ == '__main__':
    app.run(threaded=True)

to handle multiple clients using threads in a way compatible with old Flask versions, or

if __name__ == '__main__':
    app.run(threaded=False, processes=3)

to tell Werkzeug to spawn three processes to handle incoming requests, or just

if __name__ == '__main__':
    app.run()

to handle multiple clients using threads if you know that you will be using Flask 1.0 or later.

That being said, Werkzeug's serving.run_simple wraps the standard library's wsgiref package - and that package contains a reference implementation of WSGI, not a production-ready web server. If you are going to use Flask in production (assuming that "production" is not a low-traffic internal application with no more than 10 concurrent users) make sure to stand it up behind a real web server (see the section of Flask's docs entitled Deployment Options for some suggested methods).

I used FileReader to display image on click of the file upload button not using any Ajax requests. Following is the code hope it might help some one.

$(document).ready(function($) {
    $.extend( true, jQuery.fn, {        
        imagePreview: function( options ){          
            var defaults = {};
            if( options ){
                $.extend( true, defaults, options );
            }
            $.each( this, function(){
                var $this = $( this );              
                $this.bind( 'change', function( evt ){

                    var files = evt.target.files; // FileList object
                    // Loop through the FileList and render image files as thumbnails.
                    for (var i = 0, f; f = files[i]; i++) {
                        // Only process image files.
                        if (!f.type.match('image.*')) {
                        continue;
                        }
                        var reader = new FileReader();
                        // Closure to capture the file information.
                        reader.onload = (function(theFile) {
                            return function(e) {
                                // Render thumbnail.
                                    $('#imageURL').attr('src',e.target.result);                         
                            };
                        })(f);
                        // Read in the image file as a data URL.
                        reader.readAsDataURL(f);
                    }

                });
            });
        }   
    });
    $( '#fileinput' ).imagePreview();
});

Suggestions:

• Don't use Canvas as you shouldn't mix AWT with Swing components unnecessarily.
• Instead use a JPanel or JComponent.
• Don't get your Graphics object by calling getGraphics() on a component as the Graphics object obtained will be transient.
• Draw in the JPanel's paintComponent() method.
• All this is well explained in several tutorials that are easily found. Why not read them first before trying to guess at this stuff?

Key tutorial links:

• Basic Tutorial: Lesson: Performing Custom Painting
• More advanced information: Painting in AWT and Swing

Use currentValue instead, as the type of currentValue is EventTarget & HTMLInputElement.

Mutex: exclusive-member access to a resource

Semaphore: n-member access to a resource

That is, a mutex can be used to syncronize access to a counter, file, database, etc.

A sempahore can do the same thing but supports a fixed number of simultaneous callers. For example, I can wrap my database calls in a semaphore(3) so that my multithreaded app will hit the database with at most 3 simultaneous connections. All attempts will block until one of the three slots opens up. They make things like doing naive throttling really, really easy.

Using bash regular expressions:

re="http://([^/]+)/"
if [[ $name =~ $re ]]; then echo ${BASH_REMATCH[1]}; fi

Edit - OP asked for explanation of syntax. Regular expression syntax is a large topic which I can't explain in full here, but I will attempt to explain enough to understand the example.

re="http://([^/]+)/"

This is the regular expression stored in a bash variable, re - i.e. what you want your input string to match, and hopefully extract a substring. Breaking it down:

• http:// is just a string - the input string must contain this substring for the regular expression to match
• [] Normally square brackets are used say "match any character within the brackets". So c[ao]t would match both "cat" and "cot". The ^ character within the [] modifies this to say "match any character except those within the square brackets. So in this case [^/] will match any character apart from "/".
• The square bracket expression will only match one character. Adding a + to the end of it says "match 1 or more of the preceding sub-expression". So [^/]+ matches 1 or more of the set of all characters, excluding "/".
• Putting () parentheses around a subexpression says that you want to save whatever matched that subexpression for later processing. If the language you are using supports this, it will provide some mechanism to retrieve these submatches. For bash, it is the BASH_REMATCH array.
• Finally we do an exact match on "/" to make sure we match all the way to end of the fully qualified domain name and the following "/"

Next, we have to test the input string against the regular expression to see if it matches. We can use a bash conditional to do that:

if [[ $name =~ $re ]]; then
    echo ${BASH_REMATCH[1]}
fi

In bash, the [[ ]] specify an extended conditional test, and may contain the =~ bash regular expression operator. In this case we test whether the input string $name matches the regular expression $re. If it does match, then due to the construction of the regular expression, we are guaranteed that we will have a submatch (from the parentheses ()), and we can access it using the BASH_REMATCH array:

• Element 0 of this array ${BASH_REMATCH[0]} will be the entire string matched by the regular expression, i.e. "http://www.google.com/".
• Subsequent elements of this array will be subsequent results of submatches. Note you can have multiple submatch () within a regular expression - The BASH_REMATCH elements will correspond to these in order. So in this case ${BASH_REMATCH[1]} will contain "www.google.com", which I think is the string you want.

Note that the contents of the BASH_REMATCH array only apply to the last time the regular expression =~ operator was used. So if you go on to do more regular expression matches, you must save the contents you need from this array each time.

This may seem like a lengthy description, but I have really glossed over several of the intricacies of regular expressions. They can be quite powerful, and I believe with decent performance, but the regular expression syntax is complex. Also regular expression implementations vary, so different languages will support different features and may have subtle differences in syntax. In particular escaping of characters within a regular expression can be a thorny issue, especially when those characters would have an otherwise different meaning in the given language.

Note that instead of setting the $re variable on a separate line and referring to this variable in the condition, you can put the regular expression directly into the condition. However in bash 3.2, the rules were changed regarding whether quotes around such literal regular expressions are required or not. Putting the regular expression in a separate variable is a straightforward way around this, so that the condition works as expected in all bash versions that support the =~ match operator.

You can use drawableTop (also drawableLeft, etc) for the image and set text below the image by adding the gravity left|center_vertical

<Button
            android:id="@+id/btn_video"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_centerVertical="true"
            android:background="@null"
            android:drawableTop="@drawable/videos"
            android:gravity="left|center_vertical"
            android:onClick="onClickFragment"
            android:text="Videos"
            android:textColor="@color/white" />

In case you need to convert a timeval struct (seconds, microseconds) containing UNIX time to DateTime without losing precision, this is how:

DateTime _epochTime = new DateTime(1970, 1, 1, 0, 0, 0, DateTimeKind.Utc);
private DateTime UnixTimeToDateTime(Timeval unixTime)
{
    return _epochTime.AddTicks(
        unixTime.Seconds * TimeSpan.TicksPerSecond +
        unixTime.Microseconds * TimeSpan.TicksPerMillisecond/1000);
}

Your example:

{
    "items":
    [
        {
            "WR":"qwe",
            "QU":"asd",
            "QA":"end",
            "WO":"hasd",
            "NO":"qwer"
        },
        ...
    ]
}

add an element "itemorder"

{
    "items":
    [
        {
            "WR":"qwe",
            "QU":"asd",
            "QA":"end",
            "WO":"hasd",
            "NO":"qwer"
        },
        ...
    ],
    "itemorder":["WR","QU","QA","WO","NO"]
}

This code generates the desired output without the column title line:

JSONObject output = new JSONObject(json);
JSONArray docs = output.getJSONArray("data");
JSONArray names = output.getJSONArray("itemOrder");
String csv = CDL.toString(names,docs);

You can also use the Runtime to create a cross platform solution:

import java.awt.Desktop;
import java.net.URI;

public class App {

    public static void main(String[] args) throws Exception {
        String url = "http://stackoverflow.com";

        if (Desktop.isDesktopSupported()) {
            // Windows
            Desktop.getDesktop().browse(new URI(url));
        } else {
            // Ubuntu
            Runtime runtime = Runtime.getRuntime();
            runtime.exec("/usr/bin/firefox -new-window " + url);
        }
    }
}

For me,

Project ---> Source ---> Format

solved the problem

Assuming you are using Eclipse, on a MAC you can:

1. Launch Eclipse.app
2. Choose Eclipse -> Preferences
3. Choose Java -> Installed JREs
4. Click the Add... button
5. Choose MacOS X VM as the JRE type. Press Next.
6. In the "JRE Home:" field, type /Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
7. You should see the system libraries in the list titled "JRE system libraries:"
8. Give the JRE a name. The recommended name is JDK 1.7. Click Finish.
9. Check the checkbox next to the JRE entry you just created. This will cause Eclipse to use it as the default JRE for all new Java projects. Click OK.
10. Now, create a new project. For this verification, from the menu, select File -> New -> Java Project.
11. In the dialog that appears, enter a new name for your project. For this verification, type Test17Project
12. In the JRE section of the dialog, select Use default JRE (currently JDK 1.7)
13. Click Finish.

Hope this helps

I followed several suggestions in this list without success. Finally got it installed on Windows using this method: I extracted the zip file and placed the folders under my python27 folder. In a DOS window, I navigated to the installed root folder from extracting the zip file (python-dateutil-2.6.0), then issued this command:

.\python setup.py install

Whammo-bammo it all worked.

Actually, we really do not need to import any python library. We can separate the year, month, date using simple SQL. See the below example,

+----------+
|       _c0|
+----------+
|1872-11-30|
|1873-03-08|
|1874-03-07|
|1875-03-06|
|1876-03-04|
|1876-03-25|
|1877-03-03|
|1877-03-05|
|1878-03-02|
|1878-03-23|
|1879-01-18|

I have a date column in my data frame which contains the date, month and year and assume I want to extract only the year from the column.

df.createOrReplaceTempView("res")
sqlDF = spark.sql("SELECT EXTRACT(year from `_c0`) FROM res ")

Here I'm creating a temporary view and store the year values using this single line and the output will be,

+-----------------------+
|year(CAST(_c0 AS DATE))|
+-----------------------+
|                   1872|
|                   1873|
|                   1874|
|                   1875|
|                   1876|
|                   1876|
|                   1877|
|                   1877|
|                   1878|
|                   1878|
|                   1879|
|                   1879|
|                   1879|

I have found the try: ... else: construct useful in the situation where you are running database queries and logging the results of those queries to a separate database of the same flavour/type. Let's say I have lots of worker threads all handling database queries submitted to a queue

#in a long running loop
try:
    query = queue.get()
    conn = connect_to_db(<main db>)
    curs = conn.cursor()
    try:
        curs.execute("<some query on user input that may fail even if sanitized">)
    except DBError:
        logconn = connect_to_db(<logging db>)
        logcurs = logconn.cursor()

        logcurs.close()
        logconn.close()
    else:

        #we can't put this in main try block because an error connecting
        #to the logging DB would be indistinguishable from an error in 
        #the mainquery 

        #We can't put this after the whole try: except: finally: block
        #because then we don't know if the query was successful or not

        logconn = connect_to_db(<logging db>)
        logcurs = logconn.cursor()
        logcurs.execute("<update in DB log with record of successful query")
        logcurs.close()
        logconn.close()
        #do something in response to successful query
except DBError:
    #This DBError is because of a problem with the logging database, but 
    #we can't let that crash the whole thread over what might be a
    #temporary network glitch
finally:
    curs.close()
    conn.close()
    #other cleanup if necessary like telling the queue the task is finished

Of course if you can distinguish between the possible exceptions that might be thrown, you don't have to use this, but if code reacting to a successful piece of code might throw the same exception as the successful piece, and you can't just let the second possible exception go, or return immediately on success (which would kill the thread in my case), then this does come in handy.

It really depends on the kind of classes as not all classes are created equal.

As general guideline I would suggest 2 options:

• For value & immutable classes (Exception, Integer, DTOs and such) use single primary constructor as suggested in above answer
• For everything else (session beans, services, mutable objects, JPA & JAXB entities and so on) use default constructor only with sensible defaults on all the properties so it can be used without additional configuration

For MVC3 you don't have to add any dummy files to set a certain browser. All you have to do is:

• "Show all files" for the project
• go to bin folder
• right click the only .xml file to find the "Browse With..." option

How about (using Java 1.5 RegEx):

    String[] split = fullFileName.split("\\.");
    String ext = split[split.length - 1];

In cmd when you use > or >> the output will be only written on the file. Is it possible to see the output in the cmd windows and also save it in a file. Something similar if you use teraterm, when you can start saving all the log in a file meanwhile you use the console and view it (only for ssh, telnet and serial).

None of the above answers worked for me. Whatever I find on Internet focuses on: hide errors. None properly handles the process return-code / exit-code. I use command find within bash scripts to locate some directories and then inspect their content. I evaluate command find success using the exit-code: a value zero works, otherwise fails.

The answer provided above by Michael Brux works sometimes. But I have one scenario in which it fails! I discovered the problem and fixed it myself. I need to prune files when:

it is a directory AND has no read access AND/OR has no execute access

See the key issue here is: AND/OR. One good suggested condition sequence I read is:

-type d ! -readable ! -executable -prune

This does not work always. This means a prune is triggered when a match is:

it is directory AND no read access AND no execute access

This sequence of expressions fails when read access is granted but no execute access is.

After some testing I realized about that and changed my shell script solution to:

nice find /home*/ -maxdepth 5 -follow \
    \( -type d -a ! \( -readable -a -executable \) \) -prune \
    -o \
    \( -type d -a -readable -a -executable -a -name "${m_find_name}" \) -print

The key here is to place the "not true" for a combined expression:

has read access AND has execute access

Otherwise it has not full access, which means: prune it. This proved to work for me in one scenario which previous suggested solutions failed.

I provide below technical details for questions in the comments section. I apologize if details are excessive.

• ¿Why using command nice? I got the idea here. Initially I thought it would be nice to reduce process priority when looking an entire filesystem. I realized it makes no sense to me, as my script is limited to few directories. I reduced -maxdepth to 3.
• ¿Why search within /home*/? This it not relevant for this thread. I install all applications by hand via source code compile with non privileged users (not root). They are installed within "/home". I can have multiple binaries and versions living together. I need to locate all directories, inspect and backup in a master-slave fashion. I can have more than one "/home" (several disks running within a dedicated server).
• ¿Why using -follow? Users might create symbolic links to directories. It's usefulness depends, I need to keep record of the absolute paths found.

In Java, Regex constructor has

Regex(String pattern, RegexOption option)

So to ignore cases, use

option = RegexOption.IGNORE_CASE

There are two ways. In case of doubt, you can always just try it. If it does not work, you can add extra braces to make sure, like that:

if not ((u0 <= u) and (u < u0+step)):

Kotlin version with infix function

infix fun View.below(view: View) {
      (this.layoutParams as? RelativeLayout.LayoutParams)?.addRule(RelativeLayout.BELOW, view.id)
}

Then you can write:

view1 below view2

Or you can call it as a normal function:

view1.below(view2)

There is a React module called react-client-session that makes storing client side session data very easy. The git repo is here.

This is implemented in a similar way as the closure approach in my other answer, however it also supports persistence using 3 different persistence stores. The default store is memory(not persistent).

1. Cookie
2. localStorage
3. sessionStorage

After installing, just set the desired store type where you mount the root component ...

import ReactSession from 'react-client-session';

ReactSession.setStoreType("localStorage");

... and set/get key value pairs from anywhere in your app:

import ReactSession from 'react-client-session';

ReactSession.set("username", "Bob");
ReactSession.get("username");  // Returns "Bob"

Here are the different ways in which you can create an array of booleans in typescript:

let arr1: boolean[] = [];
let arr2: boolean[] = new Array();
let arr3: boolean[] = Array();

let arr4: Array<boolean> = [];
let arr5: Array<boolean> = new Array();
let arr6: Array<boolean> = Array();

let arr7 = [] as boolean[];
let arr8 = new Array() as Array<boolean>;
let arr9 = Array() as boolean[];

let arr10 = <boolean[]> [];
let arr11 = <Array<boolean>> new Array();
let arr12 = <boolean[]> Array();

let arr13 = new Array<boolean>();
let arr14 = Array<boolean>();

You can access them using the index:

console.log(arr[5]);

and you add elements using push:

arr.push(true);

When creating the array you can supply the initial values:

let arr1: boolean[] = [true, false];
let arr2: boolean[] = new Array(true, false);

Everything is possible only if there is enough time to research :)

What I got to do is like having people that I iterate into a ui:repeat and display names and other fields in inputs. But one of fields was singleSelect - A and depending on it value update another input - B. even ui:repeat do not have id I put and it appeared in the DOM tree

<ui:repeat id="peopleRepeat"
value="#{myBean.people}"
var="person" varStatus="status">

Than the ids in the html were something like:

myForm:peopleRepeat:0:personType
myForm:peopleRepeat:1:personType

Than in the view I got one method like:

<p:ajax event="change"
listener="#{myBean.onPersonTypeChange(person, status.index)}"/>

And its implementation was in the bean like:

String componentId = "myForm:peopleRepeat" + idx + "personType";
PrimeFaces.current().ajax().update(componentId);

So this way I updated the element from the bean with no issues. PF version 6.2

Good luck and happy coding :)

Here's one way to do it, but probably not the most efficient.

find -type d -print0 | xargs -0 -n1 bash -c 'echo -n "$1:"; ls -1 "$1" | wc -l' --

Gives output like this, with directory name followed by count of entries in that directory. Note that the output count will also include directory entries which may not be what you want.

./c/fa/l:0
./a:4
./a/c:0
./a/a:1
./a/a/b:0

I was trying to add an Azure Artifacts NuGet source.

I followed Microsoft's instructions here, with one critical oversight.

I forgot to replace /v3/index.json with /v2.

If you aren't comfortable with using negative margins, check this out.

div {
  position: fixed;
  left: 50%;
  bottom: 20px;
  transform: translate(-50%, -50%);
  margin: 0 auto;
}

<div>
  Your Text
</div>

Especially useful when you don't know the width of the div.

align="center" has no effect.

Since you have position:absolute, I would recommend positioning it 50% from the left and then subtracting half of its width from its left margin.

#manipulate {
    position:absolute;
    width:300px;
    height:300px;
    background:#063;
    bottom:0px;
    right:25%;
    left:50%;
    margin-left:-150px;
}

1) This works without imports in Python 2:

>>>
>>> 'Some text'.encode('base64')
'U29tZSB0ZXh0\n'
>>>
>>> 'U29tZSB0ZXh0\n'.decode('base64')
'Some text'
>>>
>>> 'U29tZSB0ZXh0'.decode('base64')
'Some text'
>>>

(although this doesn't work in Python3 )

2) In Python 3 you'd have to import base64 and do base64.b64decode('...') - will work in Python 2 too.

all please check the updated code as we have to use

 form-control-static not only form-control

I found that the cleanest way to do this is to create a custom TwigExtension and override its getGlobals() method. Rather than using $_SESSION, it's also better to use Symfony's Session class since it handles automatically starting/stopping the session.

I've got the following extension in /src/AppBundle/Twig/AppExtension.php:

<?php    
namespace AppBundle\Twig;

use Symfony\Component\HttpFoundation\Session\Session;

class AppExtension extends \Twig_Extension {

    public function getGlobals() {
        $session = new Session();
        return array(
            'session' => $session->all(),
        );
    }

    public function getName() {
        return 'app_extension';
    }
}

Then add this in /app/config/services.yml:

services:
    app.twig_extension:
        class: AppBundle\Twig\AppExtension
        public: false
        tags:
            - { name: twig.extension }

Then the session can be accessed from any view using:

{{ session.my_variable }}

You don't have to cram multiple operations into one stream/lambda. Consider separating them into 2 statements (using static import of toList()):

entryList.forEach(e->e.setTempId(tempId));

List<Entry> updatedEntries = entryList.stream()
  .map(e->entityManager.update(entry, entry.getId()))
  .collect(toList());

Try this one. (LINK)

You've already got a working answer but just in case you are curious what was wrong with your original approach, the answer is that you need parentheses around your alternation otherwise the (\.|$) is only required if the number is less than 200.

'\b((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(\.|$)){4}\b'
    ^                                    ^

I had the same issue and believe that it has to do with the size of the repo (edited- or the size of a particular file) you are trying to push.

Basically I was able to create new repos and push them to github. But an existing one would not work.

The HTTP error code seems to back me up it is a 'Length Required' error. So maybe it is too large to calc or greated that the max. Who knows.

EDIT

I found that the problem may be files that are large. I had one update that would not push even though I had successful pushes up to that point. There was only one file in the commit but it happened to be 1.6M

So I added the following config change

git config http.postBuffer 524288000

To allow up to the file size 500M and then my push worked. It may have been that this was the problem initially with pushing a big repo over the http protocol.

END EDIT

the way I could get it to work (EDIT before I modified postBuffer) was to tar up my repo, copy it to a machine that can do git over ssh, and push it to github. Then when you try to do a push/pull from the original server it should work over https. (since it is a much smaller amount of data than an original push).

here it's a simple:

File file = new File(path);
int size = (int) file.length();
byte[] bytes = new byte[size];
try {
    BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
    buf.read(bytes, 0, bytes.length);
    buf.close();
} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Add permission in manifest.xml:

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

For me a typical while loop will be something like this:

xBool = True
# A counter to force a condition (eg. yCount = some integer value)

while xBool:
    # set up the condition (eg. if yCount > 0):
        (Do something)
        yCount = yCount - 1
    else:
        # (condition is not met, set xBool False)
        xBool = False

I could include a for..loop within the while loop as well, if situation so warrants, for looping through another set of condition.

Here you go:

date +%Y%m%d%H%M%S

As man date says near the top, you can use the date command like this:

date [OPTION]... [+FORMAT]

That is, you can give it a format parameter, starting with a +. You can probably guess the meaning of the formatting symbols I used:

• %Y is for year
• %m is for month
• %d is for day
• ... and so on

You can find this, and other formatting symbols in man date.

You can make you request headers by yourself using:

// open a socket connection on port 80
$fp = fsockopen($host, 80);

// send the request headers:
fputs($fp, "POST $path HTTP/1.1\r\n");
fputs($fp, "Host: $host\r\n");
fputs($fp, "Referer: $referer\r\n");
fputs($fp, "Content-type: application/x-www-form-urlencoded\r\n");
fputs($fp, "Content-length: ". strlen($data) ."\r\n");
fputs($fp, "Connection: close\r\n\r\n");
fputs($fp, $data);

$result = ''; 
while(!feof($fp)) {
    // receive the results of the request
    $result .= fgets($fp, 128);
}

// close the socket connection:
fclose($fp);

Like writen on how make request

Make use of the zfill() helper method to left-pad any string, integer or float with zeros; it's valid for both Python 2.x and Python 3.x.

Sample usage:

print str(1).zfill(3);
# Expected output: 001

Description:

When applied to a value, zfill() returns a value left-padded with zeros when the length of the initial string value less than that of the applied width value, otherwise, the initial string value as is.

Syntax:

str(string).zfill(width)
# Where string represents a string, an integer or a float, and
# width, the desired length to left-pad.

With the multiplication, I recommend using the modulo operator (%) to determine which numbers divide evenly into the target number like:

$factors = array();
for($i = 0; $i < $target; $i++){
    if($target % $i == 0){
        $temp = array()
        $a = $i;
        $b = $target / $i;
        $temp["a"] = $a;
        $temp["b"] = $b;
        $temp["index"] = $i;
        array_push($factors, $temp);
    }
}

This would leave you with an array of factors of the target number.

You can do that with StringUtils (from Apache Commons Lang). It avoids index-magic, so it's easier to understand. Unfortunately substringAfterLast returns empty string when there is no separator in the input string so we need the if statement for that case.

public static String getLastWord(String input) {
    String wordSeparator = " ";
    boolean inputIsOnlyOneWord = !StringUtils.contains(input, wordSeparator);
    if (inputIsOnlyOneWord) {
        return input;
    }
    return StringUtils.substringAfterLast(input, wordSeparator);
}

// Return today's date and time
var currentTime = new Date()

// returns the month (from 0 to 11)
var month = currentTime.getMonth() + 1

// returns the day of the month (from 1 to 31)
var day = currentTime.getDate()

// returns the year (four digits)
var year = currentTime.getFullYear()

// write output MM/dd/yyyy
document.write(month + "/" + day + "/" + year)

Basically the double-curly syntax is more naturally readable and requires less typing.

Both cases produce the same output but.. if you choose to go with {{}} there is a chance that the user will see for some milliseconds the {{}} before your template is rendered by angular. So if you notice any {{}} then is better to use ng-bind.

Also very important is that only in your index.html of your angular app you can have un-rendered {{}}. If you are using directives so then templates, there is no chance to see that because angular first render the template and after append it to the DOM.

If you want to carry on using CSS3 selectors but need to support older browsers I would suggest using a polyfill such as Selectivizr.js

Most of answers are perfect here, but when I landed here for my particular problem, I have to upload binary file (XLSX spread sheet) using POST method, I see one thing missing, i.e. usually its not just file you load, you may have more form data elements, like comment to file or tags to file etc as was my case. Hence, I would like to add it here as it was my use case, so that it could help others.

curl -POST -F comment=mycomment -F file_type=XLSX -F file_data=@/your/path/to/file.XLSX http://yourhost.example.com/api/example_url

Another option would be using flexbox.

While it's not supported by IE8 and IE9, you could consider:

• Not minding about those old IE versions
• Providing a fallback
• Using a polyfill

Despite some additional browser-specific style prefixing would be necessary for full cross-browser support, you can see the basic usage either on this fiddle and on the following snippet:

html {_x000D_
  height: 100%;_x000D_

I discovered that this behaviour only occurs after running a particular script, similar to the one in the question. I have no idea why it occurs.

It works (refreshes the graphs) if I put

plt.clf()
plt.cla()
plt.close()

after every plt.show()

They're not bad practice, they're just another tool and they add flexibility.

For use as a standard page element... they're good, because they're a simple and reliable way to separate content onto several pages. Especially for user-generated content, it may be useful to "sandbox" internal pages into an iframe so poor markup doesn't affect the main page. The downside is that if you introduce multiple layers of scrolling (one for the browser, one for the iframe) your users will get frustrated. Like adzm said, you don't want to use an iframe for primary navigation, but think about them as a text/markup equivalent to the way a video or another media file would be embedded.

For scripting background events, the choice is generally between a hidden iframe and XmlHttpRequest to load content for the current page. The difference there is that an iframe generates a page load, so you can move back and forward in browser cache with most browsers. Notice that Google, who uses XmlHttpRequest all over the place, also uses iframes in certain cases to allow a user to move back and forward in browser history.

Here is a self-contained example, with easily manipulated test data.

With this example, if you have a name with more than three parts, then all the "extra" stuff will get put in the LAST_NAME field. An exception is made for specific strings that are identified as "titles", such as "DR", "MRS", and "MR".

If the middle name is missing, then you just get FIRST_NAME and LAST_NAME (MIDDLE_NAME will be NULL).

You could smash it into a giant nested blob of SUBSTRINGs, but readability is hard enough as it is when you do this in SQL.

Edit-- Handle the following special cases:

1 - The NAME field is NULL

2 - The NAME field contains leading / trailing spaces

3 - The NAME field has > 1 consecutive space within the name

4 - The NAME field contains ONLY the first name

5 - Include the original full name in the final output as a separate column, for readability

6 - Handle a specific list of prefixes as a separate "title" column

Just append() the text nodes:

$('#replyBox').append(quote); 

http://jsfiddle.net/nQErc/

<html>
<head>
<script type="text/javascript">
function GetTimeZoneOffset() {
    var d = new Date()
    var gmtOffSet = -d.getTimezoneOffset();
    var gmtHours = Math.floor(gmtOffSet / 60);
    var GMTMin = Math.abs(gmtOffSet % 60);
    var dot = ".";
    var retVal = "" + gmtHours + dot + GMTMin;
    document.getElementById('<%= offSet.ClientID%>').value = retVal;
}

</script>
</head>
<body onload="GetTimeZoneOffset()">
    <asp:HiddenField ID="clientDateTime" runat="server" />
    <asp:HiddenField ID="offSet" runat="server" />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
</body>
</html>

key point to notice here is,body has an attribute onload. Just give it a function name and that function will be called on page load.

Alternatively, you can also call the function on page load event like this

<html>
<head>
<script type="text/javascript">

window.onload = load();

function load() {
    var d = new Date()
    var gmtOffSet = -d.getTimezoneOffset();
    var gmtHours = Math.floor(gmtOffSet / 60);
    var GMTMin = Math.abs(gmtOffSet % 60);
    var dot = ".";
    var retVal = "" + gmtHours + dot + GMTMin;
    document.getElementById('<%= offSet.ClientID%>').value = retVal;
}

</script>
</head>
<body >
    <asp:HiddenField ID="clientDateTime" runat="server" />
    <asp:HiddenField ID="offSet" runat="server" />
    <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox></body>
</body>
</html>

You could define a macro containing the following code:

Sub DeleteA5X50()   
    Range("A5:X50").Select
    Selection.ClearContents
end sub

Running the macro would select the range A5:x50 on the active worksheet and clear all the contents of the cells within that range.

To leave your formulas intact use the following instead:

Sub DeleteA5X50()   
    Range("A5:X50").Select
    Selection.SpecialCells(xlCellTypeConstants, 23).Select
    Selection.ClearContents
end sub

This will first select the overall range of cells you are interested in clearing the contents from and will then further limit the selection to only include cells which contain what excel considers to be 'Constants.'

You can do this manually in excel by selecting the range of cells, hitting 'f5' to bring up the 'Go To' dialog box and then clicking on the 'Special' button and choosing the 'Constants' option and clicking 'Ok'.

You will need a PDF renderer. There are a few more or less good ones on the market (ICEPdf, pdfrenderer), but without, you will have to rely on external tools. The free PDF renderers also cannot render embedded fonts, and so will only be good for creating thumbnails (what you eventually want).

My favorite external tool is Ghostscript, which can convert PDFs to images with a single command line invocation.

This converts Postscript (and PDF?) files to bmp for us, just as a guide to modify for your needs (Know you need the env vars for gs to work!):

pushd 
setlocal

Set BIN_DIR=C:\Program Files\IKOffice_ACME\bin
Set GS=C:\Program Files\IKOffice_ACME\gs
Set GS_DLL=%GS%\gs8.54\bin\gsdll32.dll
Set GS_LIB=%GS%\gs8.54\lib;%GS%\gs8.54\Resource;%GS%\fonts
Set Path=%Path%;%GS%\gs8.54\bin
Set Path=%Path%;%GS%\gs8.54\lib

call "%GS%\gs8.54\bin\gswin32c.exe" -q -dSAFER -dNOPAUSE -dBATCH -sDEVICE#bmpmono -r600x600 -sOutputFile#%2 -f %1

endlocal
popd

UPDATE: pdfbox is now able to embed fonts, so no need for Ghostscript anymore.

git remote set-url origin <URL>

You forgot to specify the variable name. It should be CERas.CERAS newCeras = new CERas.CERAS();

Well, you can hide it, by removing the entire system menu:

private const int WS_SYSMENU = 0x80000;
protected override CreateParams CreateParams
{
    get
    {
        CreateParams cp = base.CreateParams;
        cp.Style &= ~WS_SYSMENU;
        return cp;
    }
}

Of course, doing so removes the minimize and maximize buttons.

If you keep the system menu but remove the close item then the close button remains but is disabled.

The final alternative is to paint the non-client area yourself. That's pretty hard to get right.

CSS3 grab and grabbing are now allowed values for cursor. In order to provide several fallbacks for cross-browser compatibility3 including custom cursor files, a complete solution would look like this:

.draggable {
    cursor: move; /* fallback: no `url()` support or images disabled */
    cursor: url(images/grab.cur); /* fallback: Internet Explorer */
    cursor: -webkit-grab; /* Chrome 1-21, Safari 4+ */
    cursor:    -moz-grab; /* Firefox 1.5-26 */
    cursor:         grab; /* W3C standards syntax, should come least */
}

.draggable:active {
    cursor: url(images/grabbing.cur);
    cursor: -webkit-grabbing;
    cursor:    -moz-grabbing;
    cursor:         grabbing;
}

Update 2019-10-07:

.draggable {
    cursor: move; /* fallback: no `url()` support or images disabled */
    cursor: url(images/grab.cur); /* fallback: Chrome 1-21, Firefox 1.5-26, Safari 4+, IE, Edge 12-14, Android 2.1-4.4.4 */
    cursor: grab; /* W3C standards syntax, all modern browser */
}

.draggable:active {
    cursor: url(images/grabbing.cur);
    cursor: grabbing;
}

The other approach would be to allocate one contiguous chunk of memory comprising header block for pointers to rows as well as body block to store actual data in rows. Then just mark up memory by assigning addresses of memory in body to the pointers in header on per-row basis. It would look like follows:

int** 2dAlloc(int rows, int* columns) {    
    int header = rows * sizeof(int*);

    int body = 0;
    for(int i=0; i<rows; body+=columnSizes[i++]) {  
    }
    body*=sizeof(int);

    int** rowptr = (int**)malloc(header + body);

    int* buf  = (int*)(rowptr + rows);
    rowptr[0] = buf;
    int k;
    for(k = 1; k < rows; ++k) {
        rowptr[k] = rowptr[k-1] + columns[k-1];
    }
    return rowptr;
}

int main() {
    // specifying column amount on per-row basis
    int columns[] = {1,2,3};
    int rows = sizeof(columns)/sizeof(int);
    int** matrix = 2dAlloc(rows, &columns);

    // using allocated array
    for(int i = 0; i<rows; ++i) {
        for(int j = 0; j<columns[i]; ++j) {
            cout<<matrix[i][j]<<", ";
        }   
            cout<<endl;
    }

    // now it is time to get rid of allocated 
    // memory in only one call to "free"
    free matrix;
}

The advantage of this approach is elegant freeing of memory and ability to use array-like notation to access elements of the resulting 2D array.

JavaScript Code

function ctrl($scope){
$scope.call={state:['second','first','nothing','Never', 'Gonna', 'Give', 'You', 'Up']}


$scope.whatClassIsIt= function(someValue){
     if(someValue=="first")
            return "ClassA"
     else if(someValue=="second")
         return "ClassB";
    else
         return "ClassC";
}
}

This will use less memory, since it doesn't load the whole file into memory:

$file="largefile.txt";
$linecount = 0;
$handle = fopen($file, "r");
while(!feof($handle)){
  $line = fgets($handle);
  $linecount++;
}

fclose($handle);

echo $linecount;

fgets loads a single line into memory (if the second argument $length is omitted it will keep reading from the stream until it reaches the end of the line, which is what we want). This is still unlikely to be as quick as using something other than PHP, if you care about wall time as well as memory usage.

The only danger with this is if any lines are particularly long (what if you encounter a 2GB file without line breaks?). In which case you're better off doing slurping it in in chunks, and counting end-of-line characters:

$file="largefile.txt";
$linecount = 0;
$handle = fopen($file, "r");
while(!feof($handle)){
  $line = fgets($handle, 4096);
  $linecount = $linecount + substr_count($line, PHP_EOL);
}

fclose($handle);

echo $linecount;

I think it's also worth mentioning that you will also get the message when you try to link to object of any class that has at least one virtual method and linker cannot find the file. For example:

Foo.hpp:

class Foo
{
public:
    virtual void StartFooing();
};

Foo.cpp:

#include "Foo.hpp"

void Foo::StartFooing(){ //fooing }

Compiled with:

g++ Foo.cpp -c

And main.cpp:

#include "Foo.hpp"

int main()
{
    Foo foo;
}

Compiled and linked with:

g++ main.cpp -o main

Gives our favourite error:

/tmp/cclKnW0g.o: In function main': main.cpp:(.text+0x1a): undefined reference tovtable for Foo' collect2: error: ld returned 1 exit status

This occure from my undestanding becasue:

1. Vtable is created per class at compile time

2. Linker does not have access to vtable that is in Foo.o

You can use Radium - it is an open source tool for inline styles with ReactJS. It adds exactly the selectors you need. Very popular, check it out - Radium on npm

As said @Jack, when mouseup happens outside of browser window, we are not aware of it...

This code (almost) worked for me:

window.addEventListener('mouseup', mouseUpHandler, false);
window.addEventListener('mousedown', mouseDownHandler, false);

Unfortunately, I won't get the mouseup event in one of those cases:

• user simultaneously presses a keyboard key and a mouse button, releases mouse button outside of browser window then releases key.
• user presses two mouse buttons simultaneously, releases one mouse button then the other one, both outside of browser window.

I was setting up cors.support.credentials to true along with cors.allowed.origins as *, which won't work.

When cors.allowed.origins is * , then cors.support.credentials should be false (default value or shouldn't be set explicitly).

To generate a shared library you need first to compile your C code with the -fPIC (position independent code) flag.

gcc -c -fPIC hello.c -o hello.o

This will generate an object file (.o), now you take it and create the .so file:

gcc hello.o -shared -o libhello.so

EDIT: Suggestions from the comments:

You can use

gcc -shared -o libhello.so -fPIC hello.c

to do it in one step. – Jonathan Leffler

I also suggest to add -Wall to get all warnings, and -g to get debugging information, to your gcc commands. – Basile Starynkevitch

Webpack is a bundler. Like Browserfy it looks in the codebase for module requests (require or import) and resolves them recursively. What is more, you can configure Webpack to resolve not just JavaScript-like modules, but CSS, images, HTML, literally everything. What especially makes me excited about Webpack, you can combine both compiled and dynamically loaded modules in the same app. Thus one get a real performance boost, especially over HTTP/1.x. How exactly you you do it I described with examples here http://dsheiko.com/weblog/state-of-javascript-modules-2017/ As an alternative for bundler one can think of Rollup.js (https://rollupjs.org/), which optimizes the code during compilation, but stripping all the found unused chunks.

For AMD, instead of RequireJS one can go with native ES2016 module system, but loaded with System.js (https://github.com/systemjs/systemjs)

Besides, I would point that npm is often used as an automating tool like grunt or gulp. Check out https://docs.npmjs.com/misc/scripts. I personally go now with npm scripts only avoiding other automation tools, though in past I was very much into grunt. With other tools you have to rely on countless plugins for packages, that often are not good written and not being actively maintained. npm knows its packages, so you call to any of locally installed packages by name like:

{
  "scripts": {
    "start": "npm http-server"
  },
  "devDependencies": {
    "http-server": "^0.10.0"
  }
}

Actually you as a rule do not need any plugin if the package supports CLI.

Typescript: following should work,

export const getTimeBetweenDates = ({
  until,
  format
}: {
  until: number;
  format: 'seconds' | 'minutes' | 'hours' | 'days';
}): number => {
  const date = new Date();
  const remainingTime = new Date(until * 1000);
  const getFrom = moment([date.getUTCFullYear(), date.getUTCMonth(), date.getUTCDate()]);
  const getUntil = moment([remainingTime.getUTCFullYear(), remainingTime.getUTCMonth(), remainingTime.getUTCDate()]);
  const diff = getUntil.diff(getFrom, format);
  return !isNaN(diff) ? diff : null;
};

Here's a lightweight way to do so:

String responseString = "";
for (int i = 0; i < response.getEntity().getContentLength(); i++) { 
    responseString +=
    Character.toString((char)response.getEntity().getContent().read()); 
}

With of course responseString containing website's response and response being type of HttpResponse, returned by HttpClient.execute(request)

You can use Enum.GetNames to return an IEnumerable of values in your enum and then .Count the resulting IEnumerable.

GetNames produces much the same result as GetValues but is faster.

I found a way to make a textarea with all this working at the same time:

• With horizontal scrollbar
• Supporting multiline text
• Text not wrapping

It works well on:

• Chrome 15.0.874.120
• Firefox 7.0.1
• Opera 11.52 (1100)
• Safari 5.1 (7534.50)
• IE 8.0.6001.18702

Let me explain how i get to that: I was using Chrome inspector integrated tool and I saw values on CSS styles, so I try these values, instead of normal ones... trial & errors till I got it reduced to minimum and here it is for anyone that wants it.

In the CSS section I used just this for Chrome, Firefox, Opera and Safari:

textarea {
  white-space:nowrap;
  overflow:scroll;
}

In the CSS section I used just this for IE:

textarea {
  overflow:scroll;
}

It was a bit tricky, but there is the CSS.

An (x)HTML tag like this:

<textarea id="myTextarea" rows="10" cols="15"></textarea>

And at the end of the <head> section a JavaScript like this:

 window.onload=function(){
   document.getElementById("myTextarea").wrap='off';
 }

The JavaScript is for making the W3C validator passing XHTML 1.1 Strict, since the wrap attribute is not official and thus cannot be an (x)HTML tag directly, but most browsers handle it, so after loading the page it sets that attribute.

Hope this can be tested on more browsers and versions and help someone to improve it and makes it fully cross-browser for all versions.

The final keyword has several usages in Java. It corresponds to both the sealed and readonly keywords in C#, depending on the context in which it is used.

Classes

To prevent subclassing (inheritance from the defined class):

Java

public final class MyFinalClass {...}

C#

public sealed class MyFinalClass {...}

Methods

Prevent overriding of a virtual method.

Java

public class MyClass
{
    public final void myFinalMethod() {...}
}

C#

public class MyClass : MyBaseClass
{
    public sealed override void MyFinalMethod() {...}
}

As Joachim Sauer points out, a notable difference between the two languages here is that Java by default marks all non-static methods as virtual, whereas C# marks them as sealed. Hence, you only need to use the sealed keyword in C# if you want to stop further overriding of a method that has been explicitly marked virtual in the base class.

Variables

To only allow a variable to be assigned once:

Java

public final double pi = 3.14; // essentially a constant

C#

public readonly double pi = 3.14; // essentially a constant

As a side note, the effect of the readonly keyword differs from that of the const keyword in that the readonly expression is evaluated at runtime rather than compile-time, hence allowing arbitrary expressions.

I had to do something very similar to find out why my iPhone was bleeding cellular network data, eating 80% of my 500Mb allowance in a couple of days.

Unfortunately I had to packet sniff whilst on 3G/4G and couldn't rely on being on wireless. So if you need an "industrial" solution then this is how you sniff all traffic (not just http) on any network.

Basic recipe:

1. Install VPN server
2. Run packet sniffer on VPN server
3. Connect iPhone to VPN server and perform operations
4. Download .pcap from VPN server and use your favourite .pcap analyser on it.

Detailed'ish instructions:

1. Get yourself a linux server, I used Fedora 20 64bit from Digirtal Ocean on a $5/month box
2. Configure OpenVPN on it. OpenVPN has comprehensive instructions
3. Ensure you configure the Routing all traffic through the VPN section
4. Be aware the instructions for (3) are all iptables which has been superseded, at time of writing, by firewall-cmd. This website explains the firewall-cmd to use
5. Check that you can connect your iPhone to the VPN. I did this by downloading the free OpenVPN software. I then set up a OpenVPN certificate. You can embed your ca, crt & key files by opening up and embedding the --- BEGIN CERTIFACTE --- ---- END CERTIFICATE --- in < ca > < /ca > < crt >< /crt>< key > < /key > blocks. Note that I had to do this in Mac with text editor, when I used notepad.exe on Win it didn't work. I then emailed this to my iphone and picked installed it.
6. Check the iPhone connects to VPN and routes it's traffic through (google what's my IP should return the VPN server IP when you run it on iPhone)
7. Now that you can connect go to your linux server & install wireshark (yum install wireshark)
8. This installs tshark, which is a command line packet sniffer. Run this in the background with screen tshark -i tun0 -x -w capture.pcap -F pcap (assuming vpn device is tun0)
9. Now when you want to capture traffic simply start the VPN on your machine
10. When complete switch off the VPN
11. Download the .pcap file from your server, and run analysis as you normally would. It's been decrypted on the server when it arrives so the traffic is viewable in plain text (obviously https still encrypted)

Note that the above implementation is not security focussed it's simply about getting a detailed packet capture of all of your iPhone's traffic on 3G/4G/Wireless networks

cp -r ./SourceFolder ./DestFolder

If anyone came here to replace a character for the first occurrence in all lines (like myself), use this:

sed '/old/s/old/new/1' file

-bash-4.2$ cat file
123a456a789a
12a34a56
a12
-bash-4.2$ sed '/a/s/a/b/1' file
123b456a789a
12b34a56
b12

By changing 1 to 2 for example, you can replace all the second a's only instead.

Since C++17 you can use range-based for loops together with structured bindings for iterating over your map. This improves readability, as you reduce the amount of needed first and second members in your code:

std::map<std::string, std::pair<std::string, std::string>> myMap;
myMap["x"] = { "a", "b" };
myMap["y"] = { "c", "d" };

for (const auto &[k, v] : myMap)
    std::cout << "m[" << k << "] = (" << v.first << ", " << v.second << ") " << std::endl;

Output:

m[x] = (a, b)
m[y] = (c, d)

I have to agree with Vladimir. I too looked into using UNION in HQL and couldn't find a way around it. The odd thing was that I could find (in the Hibernate FAQ) that UNION is unsupported, bug reports pertaining to UNION marked 'fixed', newsgroups of people saying that the statements would be truncated at UNION, and other newsgroups of people reporting it works fine... After a day of mucking with it, I ended up porting my HQL back to plain SQL, but doing it in a View in the database would be a good option. In my case, parts of the query were dynamically generated, so I had to build the SQL in the code instead.

I made an alias so that whenever I create a new branch, it will push and track the remote branch accordingly. I put following chunk into the .bash_profile file:

# Create a new branch, push to origin and track that remote branch
publishBranch() {
  git checkout -b $1
  git push -u origin $1
}
alias gcb=publishBranch

Usage: just type gcb thuy/do-sth-kool with thuy/do-sth-kool is my new branch name.

While the other answers are correct, using the "-s" option will also show the file is empty even if the file does not exist.
By adding this additional check "-f" to see if the file exists first, we ensure the result is correct.

if [ -f diff.txt ]
then
  if [ -s diff.txt ]
  then
    rm -f empty.txt
    touch full.txt
  else
    rm -f full.txt
    touch empty.txt
  fi
else
  echo "File diff.txt does not exist"
fi

nametext is an std::string but these do not have the stream insertion operator (<<) like output streams do.

To concatenate strings you can use the append member function (or its equivalent, +=, which works in the exact same way) or the + operator, which creates a new string as a result of concatenating the previous two.

There is no disabled attribute for hyperlinks. If you don't want something to be linked then you'll need to remove the <a> tag altogether.

Alternatively you can remove its href attribute - though this has other UX and Accessibility issues as noted in the comments below so is not recommended.

Expanding on a previous answer, this removes all new lines and saves the result to a new file (thanks to @tripleee):

tr -d '\n' < yourfile.txt > yourfile2.txt

Which is better than a "useless cat" (see comments):

cat file.txt | tr -d '\n' > file2.txt

Also useful for getting rid of new lines at the end of the file, e.g. created by using echo blah > file.txt.

Don't forget nProf - a prefectly good, freeware profiler.

As Hunter McMillen mentioned, tuples are immutable, you need to create a new tuple in order to achieve this. For instance:

>>> tpl = ('275', '54000', '0.0', '5000.0', '0.0')
>>> change_value = 200
>>> tpl = (change_value,) + tpl[1:]
>>> tpl
(200, '54000', '0.0', '5000.0', '0.0')

Alex mentioned memory efficiency, and Roberto mentions convenience, and these are both good points. For a few more ideas, I'll mention speed and functionality.

Functionality: You get a lot built in with NumPy, FFTs, convolutions, fast searching, basic statistics, linear algebra, histograms, etc. And really, who can live without FFTs?

Speed: Here's a test on doing a sum over a list and a NumPy array, showing that the sum on the NumPy array is 10x faster (in this test -- mileage may vary).

from numpy import arange
from timeit import Timer

Nelements = 10000
Ntimeits = 10000

x = arange(Nelements)
y = range(Nelements)

t_numpy = Timer("x.sum()", "from __main__ import x")
t_list = Timer("sum(y)", "from __main__ import y")
print("numpy: %.3e" % (t_numpy.timeit(Ntimeits)/Ntimeits,))
print("list:  %.3e" % (t_list.timeit(Ntimeits)/Ntimeits,))

which on my systems (while I'm running a backup) gives:

numpy: 3.004e-05
list:  5.363e-04

you need double quotes in all your three if statements, eg.:

IF "%a%"=="2" (

@echo OFF &SETLOCAL ENABLEDELAYEDEXPANSION

echo 2.Enable/Disable Writing Data onto USB Storage.
echo 3.~Yet to come~.

echo %a%

IF "%a%"=="2" (
    title USB WRITE LOCK
    echo What do you want to do?
    echo 1.Apply USB Write Protection
    echo 2.Remove USB Write Protection
    ::param1
    set "param1=%globalparam2%"
    goto :param1Check
    :param1Prompt
    set /p "param1=Enter Choice: "
    :param1Check

    )

    )
)

As others have pointed out, you can only use werkzeug.server.shutdown from a request handler. The only way I've found to shut down the server at another time is to send a request to yourself. For example, the /kill handler in this snippet will kill the dev server unless another request comes in during the next second:

import requests
from threading import Timer
from flask import request
import time

LAST_REQUEST_MS = 0
@app.before_request
def update_last_request_ms():
    global LAST_REQUEST_MS
    LAST_REQUEST_MS = time.time() * 1000


@app.route('/seriouslykill', methods=['POST'])
def seriouslykill():
    func = request.environ.get('werkzeug.server.shutdown')
    if func is None:
        raise RuntimeError('Not running with the Werkzeug Server')
    func()
    return "Shutting down..."


@app.route('/kill', methods=['POST'])
def kill():
    last_ms = LAST_REQUEST_MS
    def shutdown():
        if LAST_REQUEST_MS <= last_ms:  # subsequent requests abort shutdown
            requests.post('http://localhost:5000/seriouslykill')
        else:
            pass

    Timer(1.0, shutdown).start()  # wait 1 second
    return "Shutting down..."

Hey I had the same issue.
You can find all the packages in the link below:
http://www.lfd.uci.edu/~gohlke/pythonlibs/#scikit-learn
And choose the package you need for your version of windows and python.

You have to download the file with whl extension. After that, you will copy the file into your python directory then run the following command:
py -3.6 -m pip install matplotlib-2.1.0-cp36-cp36m-win_amd64.whl

Here is an example when I wanted to install matplolib for my python 3.6 https://www.youtube.com/watch?v=MzV4N4XUvYc
and this is the video I followed.

In my case, I wanted to have several windows pop up as they are being computed. For reference, this is the way:

from matplotlib.pyplot import draw, figure, show
f1, f2 = figure(), figure()
af1 = f1.add_subplot(111)
af2 = f2.add_subplot(111)
af1.plot([1,2,3])
af2.plot([6,5,4])
draw() 
print 'continuing computation'
show()

PS. A quite useful guide to matplotlib's OO interface.

Set rs = me.RecordsetClone
rs.Bookmark = me.Bookmark
Do
    rs.movenext
Loop until rs.eof

UPDATE databaseName.tableName
SET columnName = replace(columnName, '?', '''')

For Data access you can use OData. Here is a demo where Scott Hanselman creates an OData front end to StackOverflow database in 30 minutes, with XML and JSON access: Creating an OData API for StackOverflow including XML and JSON in 30 minutes.

For administrative access, like phpMyAdmin package, there is no well established one. You may give a try to IIS Database Manager.

You could use createElement() method for creating that textbox

Start from m2e 0.13.0 (if not earlier than), you can convert a Java project to Maven project from the context menu. Here is how:

• Right click the Java project to pop up the context menu
• Select Configure > Convert to Maven Project

Here is the detailed steps with screen shots.

You MUST override the "stop()" method in your Application instance to make it works. If you have overridden even empty "stop()" then the application shuts down gracefully after the last stage is closed (actually the last stage must be the primary stage to make it works completely as in supposed to be). No any additional Platform.exit or setOnCloseRequest calls are need in such case.

This is a cross-browser solution:

var w = window.innerWidth || document.documentElement.clientWidth || document.body.clientWidth;
var h = window.innerHeight || document.documentElement.clientHeight || document.body.clientHeight;

AJAX file uploads are now possible by passing a FormData object to the data property of the $.ajax request.

As the OP specifically asked for a jQuery implementation, here you go:

<form id="upload" enctype="multipart/form-data" action="@Url.Action("JsonSave", "Survey")" method="POST">
    <input type="file" name="fileUpload" id="fileUpload" size="23" /><br />
    <button>Upload!</button>
</form>

$('#upload').submit(function(e) {
    e.preventDefault(); // stop the standard form submission

    $.ajax({
        url: this.action,
        type: this.method,
        data: new FormData(this),
        cache: false,
        contentType: false,
        processData: false,
        success: function (data) {
            console.log(data.UploadedFileCount + ' file(s) uploaded successfully');
        },
        error: function(xhr, error, status) {
            console.log(error, status);
        }
    });
});

public JsonResult Survey()
{
    for (int i = 0; i < Request.Files.Count; i++)
    {
        var file = Request.Files[i];
        // save file as required here...
    }
    return Json(new { UploadedFileCount = Request.Files.Count });
}

You can do this without using refs. This approach is preferred, since refs can lead to fragile code. The React docs advise finding other solutions where possible:

If you have not programmed several apps with React, your first inclination is usually going to be to try to use refs to "make things happen" in your app. If this is the case, take a moment and think more critically about where state should be owned in the component hierarchy. Often, it becomes clear that the proper place to "own" that state is at a higher level in the hierarchy. Placing the state there often eliminates any desire to use refs to "make things happen" – instead, the data flow will usually accomplish your goal.

Instead, we'll use a state variable to focus the second input field.

1. Add a state variable that we'll pass as a prop to the DescriptionInput:

   initialState() {
     return {
       focusDescriptionInput: false,
     };
   }
   

2. Define a handler method that will set this state variable to true:

   handleTitleInputSubmit() {
     this.setState(focusDescriptionInput: true);
   }
   

3. Upon submitting / hitting enter / next on the TitleInput, we'll call handleTitleInputSubmit. This will set focusDescriptionInput to true.

   <TextInput 
      style = {styles.titleInput}
      returnKeyType = {"next"}
      autoFocus = {true}
      placeholder = "Title" 
      onSubmitEditing={this.handleTitleInputSubmit}
   />
   

4. DescriptionInput's focus prop is set to our focusDescriptionInput state variable. So, when focusDescriptionInput changes (in step 3), DescriptionInput will re-render with focus={true}.

   <TextInput
      style = {styles.descriptionInput}          
      multiline = {true}
      maxLength = {200}
      placeholder = "Description" 
      focus={this.state.focusDescriptionInput}
   />
   

This is a nice way to avoid using refs, since refs can lead to more fragile code :)

EDIT: h/t to @LaneRettig for pointing out that you'll need to wrap the React Native TextInput with some added props & methods to get it to respond to focus:

    // Props:
    static propTypes = { 
        focus: PropTypes.bool,
    } 

    static defaultProps = { 
        focus: false,
    } 

    // Methods:
    focus() {
        this._component.focus(); 
    } 

    componentWillReceiveProps(nextProps) {
        const {focus} = nextProps; 

        focus && this.focus(); 
    }

 function uploadFile() {
     var fileElement = document.getElementById("fileToUpload");
        var fileExtension = "";
        if (fileElement.value.lastIndexOf(".") > 0) {
            fileExtension = fileElement.value.substring(fileElement.value.lastIndexOf(".") + 1, fileElement.value.length);
        }
        if (fileExtension == "odx-d"||fileExtension == "odx"||fileExtension == "pdx"||fileExtension == "cmo"||fileExtension == "xml") {
         var fd = new FormData();
        fd.append("fileToUpload", document.getElementById('fileToUpload').files[0]);
        var xhr = new XMLHttpRequest();
        xhr.upload.addEventListener("progress", uploadProgress, false);
        xhr.addEventListener("load", uploadComplete, false);
        xhr.addEventListener("error", uploadFailed, false);
        xhr.addEventListener("abort", uploadCanceled, false);
        xhr.open("POST", "/post_uploadReq");
        xhr.send(fd);
        }
        else {
            alert("You must select a valid odx,pdx,xml or cmo file for upload");
            return false;
        }
       
      }

tried this , works very well

This is a symlink resolver in Bash that works whether the link is a directory or a non-directory:

function readlinks {(
  set -o errexit -o nounset
  declare n=0 limit=1024 link="$1"

  # If it's a directory, just skip all this.
  if cd "$link" 2>/dev/null
  then
    pwd -P
    return 0
  fi

  # Resolve until we are out of links (or recurse too deep).
  while [[ -L $link ]] && [[ $n -lt $limit ]]
  do
    cd "$(dirname -- "$link")"
    n=$((n + 1))
    link="$(readlink -- "${link##*/}")"
  done
  cd "$(dirname -- "$link")"

  if [[ $n -ge $limit ]]
  then
    echo "Recursion limit ($limit) exceeded." >&2
    return 2
  fi

  printf '%s/%s\n' "$(pwd -P)" "${link##*/}"
)}

Note that all the cd and set stuff takes place in a subshell.

Thread safe simply means that it may be used from multiple threads at the same time without causing problems. This can mean that access to any resources are synchronized, or whatever.

Have a look at: os.remove to remove existing files.

Based on IceForge's answer I prepared a reusable solution:

xaml style:

<Style x:Key="ComboBoxSelectOverlay" TargetType="TextBlock">
    <Setter Property="Grid.ZIndex" Value="10"/>
    <Setter Property="Foreground" Value="{x:Static SystemColors.GrayTextBrush}"/>
    <Setter Property="Margin" Value="6,4,10,0"/>
    <Setter Property="IsHitTestVisible" Value="False"/>
    <Setter Property="Visibility" Value="Hidden"/>
    <Style.Triggers>
        <DataTrigger Binding="{Binding}" Value="{x:Null}">
            <Setter Property="Visibility" Value="Visible"/>
        </DataTrigger>
    </Style.Triggers>
</Style>

example of use:

<Grid>
     <ComboBox x:Name="cmb"
               ItemsSource="{Binding Teams}" 
               SelectedItem="{Binding SelectedTeam}"/>
     <TextBlock DataContext="{Binding ElementName=cmb,Path=SelectedItem}"
               Text=" -- Select Team --" 
               Style="{StaticResource ComboBoxSelectOverlay}"/>
</Grid>

use

SELECT COUNT(DISTINCT productId) from  table_name WHERE keyword='$keyword'

function removeElements(){
  $('#models').html('');
}

They are completely equivalent when used with printf(). Personally, I prefer %d, it's used more often (should I say "it's the idiomatic conversion specifier for int"?).

(One difference between %i and %d is that when used with scanf(), then %d always expects a decimal integer, whereas %i recognizes the 0 and 0x prefixes as octal and hexadecimal, but no sane programmer uses scanf() anyway so this should not be a concern.)

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

The short answer is to comma-separate the folders you want to ignore in "files to exclude".

1. Start workspace wide search: CTRL+SHIFT+f
2. Expand the global search with the three-dot button
3. Enter your search term
4. As an example, in the files to exclude-input field write babel,concat to exclude the folder "babel" and the folder "concat" in the search (make sure the exclude button is enabled).
5. Press enter to get the results.

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

The bin/XXX.apk file can be built automatically as soon as you save any source file:

Window/Preferences, Android/Build, uncheck "skip packaging and indexing..."

In order to get the desired result, you must set "box-sizing: border-box" vs. the default which is "box-sizing: content-box". This is precisely the issue you are referring to (From MDN):

content-box

This is the initial and default value as specified by the CSS standard. The width and height properties are measured including only the content, but not the padding, border or margin.

border-box

The width and height properties include the content, the padding and border, but not the margin."

Reference: https://developer.mozilla.org/en-US/docs/Web/CSS/box-sizing

Compatibility for this CSS is good.

This happens when python cannot refer to your default site-packages folder where you have kept the required python files or libraries

Add these lines in the code:

import sys

sys.path.append('/usr/local/lib/python2.7/site-packages')

or before running the python command in bash move to /usr/local/lib/python2.7/site-packages directory. This is a work around if you don't want to add any thing to the code.

In case somebody needs to append the output and not overriding, it is possible to use "-a" or "--append" option of "tee" command :

ls 2>&1 | tee -a /tmp/ls.txt
ls 2>&1 | tee --append /tmp/ls.txt

If you prefer not to write your own function, try check.integer from package installr. Currently it uses VitoshKa's answer.

Also try check.numeric(v, only.integer=TRUE) from package varhandle, which has the benefit of being vectorized.

I had the same problem, and I solved it by installing :

• Redistribuable Visual C++ pour Visual Studio 2012 Update 4 (6.9 MB)
• Redistributable Visual C++ pour Visual Studio 2015 Update 1 (14.1 MB)

NB : 64 bit installation was enough, I had to uninstall / reinstall Wamp after that

Well you would need to get a file with JFileChooser and then read through the lines of the file using a scanner and the hasNext() function

http://docs.oracle.com/javase/7/docs/api/javax/swing/JFileChooser.html

once you do that you can save the line into a variable and manipulate the contents.

std::vector<std::string> split(std::string text, char delim) {
    std::string line;
    std::vector<std::string> vec;
    std::stringstream ss(text);
    while(std::getline(ss, line, delim)) {
        vec.push_back(line);
    }
    return vec;
}

split("String will be split", ' ') -> {"String", "will", "be", "split"}

split("Hello, how are you?", ',') -> {"Hello", "how are you?"}

EDIT: Here's a thing I made, this can use multi-char delimiters, albeit I'm not 100% sure if it always works:

std::vector<std::string> split(std::string text, std::string delim) {
    std::vector<std::string> vec;
    size_t pos = 0, prevPos = 0;
    while (1) {
        pos = text.find(delim, prevPos);
        if (pos == std::string::npos) {
            vec.push_back(text.substr(prevPos));
            return vec;
        }

        vec.push_back(text.substr(prevPos, pos - prevPos));
        prevPos = pos + delim.length();
    }
}

For Swift 3

I did as following because just removing from superview did not erase the buttons from array.

In getting started with require.js I ran into the issue and as a beginner the docs may as well been written in greek.

The issue I ran into was that most of the beginner examples use "anonymous defines" when you should be using a "string id".

anonymous defines

define(function() {
        return { helloWorld: function() { console.log('hello world!') } };
 })
    
  
define(function() {
        return { helloWorld2: function() { console.log('hello world again!') } };
 })

define with string id

define('moduleOne',function() {
    return { helloWorld: function() { console.log('hello world!') } };
})

 define('moduleTwo', function() {
      return { helloWorld2: function() { console.log('hello world again!') } };
})

When you use define with a string id then you will avoid this error when you try to use the modules like so:

require([ "moduleOne", "moduleTwo" ], function(moduleOne, moduleTwo) {
    moduleOne.helloWorld();
    moduleTwo.helloWorld2();
});

Private Function LoaderData(ByVal strSql As String) As DataTable
    Dim cnn As SqlConnection
    Dim dad As SqlDataAdapter

    Dim dtb As New DataTable
    cnn = New SqlConnection(My.Settings.mySqlConnectionString)
    Try
        cnn.Open()
        dad = New SqlDataAdapter(strSql, cnn)
        dad.Fill(dtb)
        cnn.Close()
        dad.Dispose()
    Catch ex As Exception
        cnn.Close()
        MsgBox(ex.Message)
    End Try
    Return dtb
End Function

I would use two classes. Keep your test class and add a second class called testhover which you only add to those you want to hover - alongside the test class. This isn't directly what you asked but without more context it feels like the best solution and is possibly the cleanest and simplest way of doing it.

Example:

.test {  border: 0px; }_x000D_
.testhover:hover {  border: 1px solid red; }

<div class="test"> blah </div>_x000D_
<div class="test"> blah </div>_x000D_
<div class="test testhover"> blah </div>

//Set Length filter. Restricting to 10 characters only
editText.setFilters(new InputFilter[]{new InputFilter.LengthFilter(MAX_LENGTH)});

//Allowing only upper case characters
editText.setFilters(new InputFilter[]{new InputFilter.AllCaps()});

//Attaching multiple filters
editText.setFilters(new InputFilter[]{new InputFilter.LengthFilter(MAX_LENGTH), new InputFilter.AllCaps()});

If using bash:

# Redirect standard out and standard error separately
% cmd >stdout-redirect 2>stderr-redirect

# Redirect standard error and out together
% cmd >stdout-redirect 2>&1

# Merge standard error with standard out and pipe
% cmd 2>&1 |cmd2

This was extremely helpful for me when trying to automate Cisco SIP phone configuration using an Excel spreadsheet as the source. My only issue was when I tried to make an array and populate it using $array | Add-Member ... as I needed to use it later on to generate the config file. Just defining an array and making it the for loop allowed it to store correctly.

$lastCell = 11 
$startRow, $model, $mac, $nOF, $ext = 1, 1, 5, 6, 7

$excel = New-Object -ComObject excel.application
$wb = $excel.workbooks.open("H:\Strike Network\Phones\phones.xlsx")
$sh = $wb.Sheets.Item(1)
$endRow = $sh.UsedRange.SpecialCells($lastCell).Row

$phoneData = for ($i=1; $i -le $endRow; $i++)
            {
                $pModel = $sh.Cells.Item($startRow,$model).Value2
                $pMAC = $sh.Cells.Item($startRow,$mac).Value2
                $nameOnPhone = $sh.Cells.Item($startRow,$nOF).Value2
                $extension = $sh.Cells.Item($startRow,$ext).Value2
                New-Object PSObject -Property @{ Model = $pModel; MAC = $pMAC; NameOnPhone = $nameOnPhone; Extension = $extension }
                $startRow++
            }

I used to have no issues adding information to an array with Add-Member but that was back in PSv2/3, and I've been away from it a while. Though the simple solution saved me manually configuring 100+ phones and extensions - which nobody wants to do.

My colleagues made a URL Rewrite rule, which reduced all URLs to a StaticFileHandler; mapped to a file path at the root of my Application physical folder.

(i.e. an over-aggressive URL rewrite means that my Controllers/Actions were not working)

Check your applications' URL Rewrite rules to confirm they do what you expect.

In my case the sql server version on my localhost is higher than that on the production server and hence some new variables were added to the generated script from the localhost. This caused errors in creating the table in the first place. Since the creation of the table failed, subsequent query on the "NON EXISITING" table also failed. Luckily, in among the long list of the sql errors, I found this "OPTIMIZE_FOR_SEQUENTIAL_KEY = OFF" to be the new varialbe in the script causing my issue. I did a search and replace and the error went away. Hope it helps someone.

If you are like me just want to print a sequence within a lambda, without get the return value (list of None).

x = range(3)
from __future__ import print_function           # if not python 3
pra = lambda seq=x: map(print,seq) and None     # pra for 'print all'
pra()
pra('abc')

1. Check if compatible Mysql for your PHP version is correctly installed. (eg. mysql-installer-community-5.5.40.1.msi for PHP 5.2.10, apache 2.2 and phpMyAdmin 3.5.2)
2. In your php\php.ini set your loadable php extensions path (eg. extension_dir = "C:\php\ext") (https://drive.google.com/open?id=1DDZd06SLHSmoFrdmWkmZuXt4DMOPIi_A)
3. (In your php\php.ini) check if extension=php_mysqli.dll is uncommented (https://drive.google.com/open?id=17DUt1oECwOdol8K5GaW3tdPWlVRSYfQ9)
4. Set your php folder (eg."C:\php") and php\ext folder (eg."C:\php\ext") as your runtime environment variable path (https://drive.google.com/open?id=1zCRRjh1Jem_LymGsgMmYxFc8Z9dUamKK)
5. Restart apache service (https://drive.google.com/open?id=1kJF5kxPSrj3LdKWJcJTos9ecKFx0ORAW)

I had the same problem with small difference:

Exception was raised at the moment of flushing

It is a different stackoverflow issue. The brief explanation was a wrong response header setting:

response.setHeader("Content-Encoding", "gzip");

despite uncompressed response data content.

So the the connection was closed by the browser.

my problem was not including the ../ before the image name

background-image: url("../image.png");

Your code should look like:

<?php
if ( that_happened ) {
    header("HTTP/1.0 500 Internal Server Error");
    die();
}

if ( something_else_happened ) {
    header("HTTP/1.0 500 Internal Server Error");
    die();
}

// Your function should return FALSE if something goes wrong
if ( !update_database() ) {
    header("HTTP/1.0 500 Internal Server Error");
    die();
}

// the script can also fail on the above line
// e.g. a mysql error occurred


header('HTTP/1.1 200 OK');
?>

I assume you stop execution if something goes wrong.

seems weird that no one proposed the CSS media query solution:

@media screen and (orientation: portrait) {
  ...
}

and the option to use a specific style sheet:

<link rel="stylesheet" type="text/css" href="css/style_p.css" media="screen and (orientation: portrait)">

Many years ago I was teaching someone to program in C. The exercise was to rotate a graphic through 90 degrees. He came back with a solution that took several minutes to complete, mainly because he was using multiplies and divides etc.

I showed him how to recast the problem using bit shifts, and the time to process came down to about 30 seconds on the non-optimizing compiler he had.

I had just got an optimizing compiler and the same code rotated the graphic in < 5 seconds. I looked at the assembly code that the compiler was generating, and from what I saw decided there and then that my days of writing assembler were over.

You are not selecting multiple indexes with PriceList[0][1][2][3][4][5][6] , instead each [] is going into a sub index.

Try this

PizzaChange=float(input("What would you like the new price for all standard pizzas to be? "))      
PriceList[0:7]=[PizzaChange]*7  
PriceList[7:11]=[PizzaChange+3]*4

If you assume that there can be duplicate values the only way to do this is to put the values in lists, sort them and compare the lists viz:

List<String> values1 = new ArrayList<String>(map1.values());
List<String> values2 = new ArrayList<String>(map2.values());
Collections.sort(values1);
Collections.sort(values2);
boolean mapsHaveEqualValues = values1.equals(values2);

If values cannot contain duplicate values then you can either do the above without the sort using sets.

First convert you datagridview's data to List, then convert List to DataTable

        public static DataTable ToDataTable<T>( this List<T> list) where T : class {
        Type type = typeof(T);
        var ps = type.GetProperties ( );
        var cols = from p in ps
                   select new DataColumn ( p.Name , p.PropertyType );

        DataTable dt = new DataTable();
        dt.Columns.AddRange(cols.ToArray());

        list.ForEach ( (l) => {
            List<object> objs = new List<object>();
            objs.AddRange ( ps.Select ( p => p.GetValue ( l , null ) ) );
            dt.Rows.Add ( objs.ToArray ( ) );
        } );

        return dt;
    }

In 1985, individuals from companies throughout the computer industry joined together to develop the POSIX (Portable Operating System Interface for Computer Environments) standard, which is based largely on the UNIX System V Interface Definition (SVID) and other earlier standardization efforts. These efforts were spurred by the U.S. government, which needed a standard computing environment to minimize its training and procurement costs. Released in 1988, POSIX is a group of IEEE standards that define the API, shell, and utility interfaces for an operating system. Although aimed at UNIX-like systems, the standards can apply to any compatible operating system. Now that these stan- dards have gained acceptance, software developers are able to develop applications that run on all conforming versions of UNIX, Linux, and other operating systems.

I fetch all items from dynamodb with the following query. It works fine. i create these function generic in zend framework and access these functions over the project.

        public function getQuerydata($tablename, $filterKey, $filterValue){
            return $this->getQuerydataWithOp($tablename, $filterKey, $filterValue, 'EQ');
        }

        public function getQuerydataWithOp($tablename, $filterKey, $filterValue, $compOperator){
        $result = $this->getClientdb()->query(array(
                'TableName'     => $tablename,
                'IndexName'     => $filterKey,
                'Select'        => 'ALL_ATTRIBUTES',
                'KeyConditions' => array(
                    $filterKey => array(
                        'AttributeValueList' => array(
                            array('S' => $filterValue)
                        ),
                'ComparisonOperator' => $compOperator
            )
            )
        ));
            return $result['Items'];
        }

       //Below i Access these functions and get data.
       $accountsimg = $this->getQuerydataWithPrimary('accounts', 'accountID',$msgdata[0]['accountID']['S']);

It's a little difficult to tell what you're trying to achieve, but assuming you're trying to get a Base64 string that when decoded is abcdef==, the following should work:

byte[] bytes = Encoding.UTF8.GetBytes("abcdef==");
string base64 = Convert.ToBase64String(bytes);
Console.WriteLine(base64);

This will output: YWJjZGVmPT0= which is abcdef== encoded in Base64.

Edit:

To decode a Base64 string, simply use Convert.FromBase64String(). E.g.

string base64 = "YWJjZGVmPT0=";
byte[] bytes = Convert.FromBase64String(base64);

At this point, bytes will be a byte[] (not a string). If we know that the byte array represents a string in UTF8, then it can be converted back to the string form using:

string str = Encoding.UTF8.GetString(bytes);
Console.WriteLine(str);

This will output the original input string, abcdef== in this case.

If you want to use Parameters and regulate the maximum number of async functions you can use a simple async worker I've build:

var BackgroundWorker = function(maxTasks) {
    this.maxTasks = maxTasks || 100;
    this.runningTasks = 0;
    this.taskQueue = [];
};

/* runs an async task */
BackgroundWorker.prototype.runTask = function(task, delay, params) {
    var self = this;
    if(self.runningTasks >= self.maxTasks) {
        self.taskQueue.push({ task: task, delay: delay, params: params});
    } else {
        self.runningTasks += 1;
        var runnable = function(params) {
            try {
                task(params);
            } catch(err) {
                console.log(err);
            }
            self.taskCompleted();
        }
        // this approach uses current standards:
        setTimeout(runnable, delay, params);
    }
}

BackgroundWorker.prototype.taskCompleted = function() {
    this.runningTasks -= 1;

    // are any tasks waiting in queue?
    if(this.taskQueue.length > 0) {
        // it seems so! let's run it x)
        var taskInfo = this.taskQueue.splice(0, 1)[0];
        this.runTask(taskInfo.task, taskInfo.delay, taskInfo.params);
    }
}

You can use it like this:

var myFunction = function() {
 ...
}
var myFunctionB = function() {
 ...
}
var myParams = { name: "John" };

var bgworker = new BackgroundWorker();
bgworker.runTask(myFunction, 0, myParams);
bgworker.runTask(myFunctionB, 0, null);

In python 3.x all strings are sequences of Unicode characters. and doing the isinstance check for str (which means unicode string by default) should suffice.

isinstance(x, str)

With regards to python 2.x, Most people seem to be using an if statement that has two checks. one for str and one for unicode.

If you want to check if you have a 'string-like' object all with one statement though, you can do the following:

isinstance(x, basestring)

Aggregation - separable part to whole. The part has a identity of its own, separate from what it is part of. You could pick that part and move it to another object. (real world examples: wheel -> car, bloodcell -> body)

Composition - non-separable part of the whole. You cannot move the part to another object. more like a property. (real world examples: curve -> road, personality -> person, max_speed -> car, property of object -> object )

Note that a relation that is an aggregate in one design can be a composition in another. Its all about how the relation is to be used in that specific design.

dependency - sensitive to change. (amount of rain -> weather, headposition -> bodyposition)

Note: "Bloodcell" -> Blood" could be "Composition" as Blood Cells can not exist without the entity called Blood. "Blood" -> Body" could be "Aggregation" as Blood can exist without the entity called Body.

You can declare SqlConnection and SqlCommand instances at global level so that you can use it through out the class. Connection string is in Web.Config.

SqlConnection sqlConn = new SqlConnection(WebConfigurationManager.ConnectionStrings["SqlConnector"].ConnectionString);
SqlCommand sqlcomm = new SqlCommand();

Now you can use the below method to pass values to Stored Procedure and get the DataSet.

public DataSet GetDataSet(string paramValue)
{
    sqlcomm.Connection = sqlConn;
    using (sqlConn)
    {
        try
        {
            using (SqlDataAdapter da = new SqlDataAdapter())
            {  
                // This will be your input parameter and its value
                sqlcomm.Parameters.AddWithValue("@ParameterName", paramValue);

                // You can retrieve values of `output` variables
                var returnParam = new SqlParameter
                {
                    ParameterName = "@Error",
                    Direction = ParameterDirection.Output,
                    Size = 1000
                };
                sqlcomm.Parameters.Add(returnParam);
                // Name of stored procedure
                sqlcomm.CommandText = "StoredProcedureName";
                da.SelectCommand = sqlcomm;
                da.SelectCommand.CommandType = CommandType.StoredProcedure;

                DataSet ds = new DataSet();
                da.Fill(ds);                            
            }
        }
        catch (SQLException ex)
        {
            Console.WriteLine("SQL Error: " + ex.Message);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
    }
    return new DataSet();
}

The following is the sample of connection string in config file

<connectionStrings>
    <add name="SqlConnector"
         connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=YourDatabaseName;User id=YourUserName;Password=YourPassword"
         providerName="System.Data.SqlClient" />
</connectionStrings>

If you don't know how to enable php_mbstring extension in windows, open your php.ini and remove the semicolon before the extension:

change this

;extension=php_mbstring.dll

to this

extension=php_mbstring.dll

after modification, you need to reset your php server.

You can reset the plot by doing this:

dev.off()

Just figure out the difference in seconds (don't forget JS timestamps are actually measured in milliseconds) and decompose that value:

// get total seconds between the times
var delta = Math.abs(date_future - date_now) / 1000;

// calculate (and subtract) whole days
var days = Math.floor(delta / 86400);
delta -= days * 86400;

// calculate (and subtract) whole hours
var hours = Math.floor(delta / 3600) % 24;
delta -= hours * 3600;

// calculate (and subtract) whole minutes
var minutes = Math.floor(delta / 60) % 60;
delta -= minutes * 60;

// what's left is seconds
var seconds = delta % 60;  // in theory the modulus is not required

EDIT code adjusted because I just realised that the original code returned the total number of hours, etc, not the number of hours left after counting whole days.

INSERT INTO ... ON DUPLICATE KEY UPDATE will only work for MYSQL, not for SQL Server.

for SQL server, the way to work around this is to first declare a temp table, insert value to that temp table, and then use MERGE

Like this:

declare @Source table
(
name varchar(30),
age decimal(23,0)
)

insert into @Source VALUES
('Helen', 24),
('Katrina', 21),
('Samia', 22),
('Hui Ling', 25),
('Yumie', 29);


MERGE beautiful  AS Tg
using  @source as Sc
on tg.namet=sc.name 

when matched then update 
set tg.age=sc.age

when not matched then 
insert (name, age) VALUES
(SC.name, sc.age);

You can use netcat for this.

nc ip port < /dev/null

connects to the server and directly closes the connection again. If netcat is not able to connect, it returns a non-zero exit code. The exit code is stored in the variable $?. As an example,

nc ip port < /dev/null; echo $?

will return 0 if and only if netcat could successfully connect to the port.

success has been the traditional name of the success callback in jQuery, defined as an option in the ajax call. However, since the implementation of $.Deferreds and more sophisticated callbacks, done is the preferred way to implement success callbacks, as it can be called on any deferred.

For example, success:

$.ajax({
  url: '/',
  success: function(data) {}
});

For example, done:

$.ajax({url: '/'}).done(function(data) {});

The nice thing about done is that the return value of $.ajax is now a deferred promise that can be bound to anywhere else in your application. So let's say you want to make this ajax call from a few different places. Rather than passing in your success function as an option to the function that makes this ajax call, you can just have the function return $.ajax itself and bind your callbacks with done, fail, then, or whatever. Note that always is a callback that will run whether the request succeeds or fails. done will only be triggered on success.

For example:

function xhr_get(url) {

  return $.ajax({
    url: url,
    type: 'get',
    dataType: 'json',
    beforeSend: showLoadingImgFn
  })
  .always(function() {
    // remove loading image maybe
  })
  .fail(function() {
    // handle request failures
  });

}

xhr_get('/index').done(function(data) {
  // do stuff with index data
});

xhr_get('/id').done(function(data) {
  // do stuff with id data
});

An important benefit of this in terms of maintainability is that you've wrapped your ajax mechanism in an application-specific function. If you decide you need your $.ajax call to operate differently in the future, or you use a different ajax method, or you move away from jQuery, you only have to change the xhr_get definition (being sure to return a promise or at least a done method, in the case of the example above). All the other references throughout the app can remain the same.

There are many more (much cooler) things you can do with $.Deferred, one of which is to use pipe to trigger a failure on an error reported by the server, even when the $.ajax request itself succeeds. For example:

function xhr_get(url) {

  return $.ajax({
    url: url,
    type: 'get',
    dataType: 'json'
  })
  .pipe(function(data) {
    return data.responseCode != 200 ?
      $.Deferred().reject( data ) :
      data;
  })
  .fail(function(data) {
    if ( data.responseCode )
      console.log( data.responseCode );
  });
}

xhr_get('/index').done(function(data) {
  // will not run if json returned from ajax has responseCode other than 200
});

Read more about $.Deferred here: http://api.jquery.com/category/deferred-object/

NOTE: As of jQuery 1.8, pipe has been deprecated in favor of using then in exactly the same way.

I guess you are using Rails 4. If so, the needed parameters must be marked as required.

You might want to do it like this:

class UsersController < ApplicationController

  def create
    @user = User.new(user_params)
    # ...

Gives you the list of files with full path:

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

I hope you get the answer.

You can send Email by Jquery just follow these steps 

include this link : <script src="https://smtpjs.com/v3/smtp.js"></script>
after that use this code :

$( document ).ready(function() {
 Email.send({
Host : "smtp.yourisp.com",
Username : "username",
Password : "password",
To : '[email protected]',
From : "[email protected]",
Subject : "This is the subject",
Body : "And this is the body"}).then( message => alert(message));});

if ($elem.parents('.left').length) {

}

You can do that by using this simple code:

Object.keys(myObject).length

That line should be sufficient:

BooleanUtils.and(boolean... array)

but to calm the link-only purists:

Performs an and on a set of booleans.

Just call plt.show() at the end:

import numpy as np
import matplotlib.pyplot as plt

plt.axis([0,50,60,80])
for i in np.arange(1,5):
    z = 68 + 4 * np.random.randn(50)
    zm = np.cumsum(z) / range(1,len(z)+1)
    plt.plot(zm)    

n = np.arange(1,51)
su = 68 + 4 / np.sqrt(n)
sl = 68 - 4 / np.sqrt(n)

plt.plot(n,su,n,sl)

plt.show()

See Introduction to the POM

finalName is created as:

<build>
    <finalName>${project.artifactId}-${project.version}</finalName>
</build>

One of the solutions is to add own property:

<properties>
    <finalName>${project.artifactId}-${project.version}</finalName>
</properties>
<build>
    <finalName>${finalName}</finalName>
 </build>

And now try:

mvn -DfinalName=build clean package

There's an option in the Simulator to open the console

Object oriented style:

$datetime1 = new DateTime('2009-10-11');
$datetime2 = new DateTime('2009-10-13');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%R%a days');

Procedural style:

$datetime1 = date_create('2009-10-11');
$datetime2 = date_create('2009-10-13');
$interval = date_diff($datetime1, $datetime2);
echo $interval->format('%R%a days');

The problem is that flex: 1 sets flex-basis: 0. Instead, you need

.container .box {
  min-width: 200px;
  max-width: 400px;
  flex-basis: auto; /* default value */
  flex-grow: 1;
}

.container {_x000D_
  display: -webkit-flex;_x000D_
  display: flex;_x000D_
  -webkit-flex-wrap: wrap;_x000D_
  flex-wrap: wrap;_x000D_
}_x000D_
_x000D_
.container .box {_x000D_
  -webkit-flex-grow: 1;_x000D_
  flex-grow: 1;_x000D_
  min-width: 100px;_x000D_
  max-width: 400px;_x000D_
  height: 200px;_x000D_
  background-color: #fafa00;_x000D_
  overflow: hidden;_x000D_
}

<div class="container">_x000D_
  <div class="box">_x000D_
    <table>_x000D_
      <tr>_x000D_
        <td>Content</td>_x000D_
        <td>Content</td>_x000D_
        <td>Content</td>_x000D_
      </tr>_x000D_
    </table>    _x000D_

  <div class="box">_x000D_

      <tr>_x000D_
        <td>Content</td>_x000D_
      </tr>_x000D_
    </table>    _x000D_
  </div>_x000D_
  <div class="box">_x000D_

Look at the following:

map(multilambda x:
      y=x+1
      return y
   , [1,2,3])

Is this a lambda returning (y, [1,2,3]) (thus map only gets one parameter, resulting in an error)? Or does it return y? Or is it a syntax error, because the comma on the new line is misplaced? How would Python know what you want?

Within the parens, indentation doesn't matter to python, so you can't unambiguously work with multilines.

This is just a simple one, there's probably more examples.

If you are trying to do something fast, efficient and readable, use a standard if...then...else structure like this:

var d = this.dealer;
if (d < 12) {
    if (d < 5) {
        alert("less than five");
    }else if (d < 9) {
        alert("between 5 and 8");
    }else{
        alert("between 9 and 11");
    }
}else{
    alert("none");
}

If you want to obfuscate it and make it awful (but small), try this:

var d=this.dealer;d<12?(d<5?alert("less than five"):d<9?alert("between 5 and 8"):alert("between 9 and 11")):alert("none");

BTW, the above code is a JavaScript if...then...else shorthand statement. It is a great example of how NOT to write code unless obfuscation or code minification is the goal. Be aware that code maintenance can be an issue if written this way. Very few people can easily read through it, if at all. The code size, however, is 50% smaller than the standard if...then...else without any loss of performance. This means that in larger codebases, minification like this can greatly speed code delivery across bandwidth constrained or high latency networks.

This, however, should not be considered a good answer. It is just an example of what CAN be done, not what SHOULD be done.

Here's an extremely simple answer

yourPlot +
  theme(
    panel.border = element_blank(), 
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(), 
    axis.line = element_line(colour = "black")
    )

It's that easy. Source: the end of this article

Its not a perfect solution, but a good workaround.

You need to assign your elements to behave as table with display: table-cell

Solution: ^Demo

HTML:

<ul>        
    <li>
        <div><input type="checkbox" value="1" name="test[]" id="myid1"></div>
        <div><label for="myid1">label1</label></div>
    </li>
    <li>
        <div><input type="checkbox" value="2" name="test[]" id="myid2"></div>
        <div><label for="myid2">label2</label></div>
    </li>
</ul>

CSS:

li div { display: table-cell; vertical-align: middle; }

This is working sample that i have tried :

Open your mail.php under config folder then fill with this option :

'driver'     => env('MAIL_DRIVER', 'smtp'),
'host'       => env('MAIL_HOST', 'smtp.gmail.com'),
'port'       => env('MAIL_PORT', 587),
'from'       => ['address' =>'[email protected]', 'name' => 'Email_Subject'],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username'   => env('MAIL_USERNAME','[email protected]'),
'password'   => env('MAIL_PASSWORD','youremailpassword'),
'sendmail'   => '/usr/sbin/sendmail -bs',

Open your .env file under root project. Also edit this file following above option such

MAIL_DRIVER=smtp    
MAIL_HOST=smtp.gmail.com   
MAIL_PORT=587      
MAIL_USERNAME=youremailusername
MAIL_PASSWORD=youremailpassword
MAIL_ENCRYPTION=tls

After that clear your config by running this command

php artisan config:cache

Restart your local server

struct rect
{
    int x;
    int y;
    int width;
    int height;
};

bool valueInRange(int value, int min, int max)
{ return (value >= min) && (value <= max); }

bool rectOverlap(rect A, rect B)
{
    bool xOverlap = valueInRange(A.x, B.x, B.x + B.width) ||
                    valueInRange(B.x, A.x, A.x + A.width);

    bool yOverlap = valueInRange(A.y, B.y, B.y + B.height) ||
                    valueInRange(B.y, A.y, A.y + A.height);

    return xOverlap && yOverlap;
}

first of all;

a Fragment must be inside a FragmentActivity, that's the first rule,

a FragmentActivity is quite similar to a standart Activity that you already know, besides having some Fragment oriented methods

second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView, where you inflate your layout, think of it as the setContentLayout

here is an example:

    @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {     mView       = inflater.inflate(R.layout.fragment_layout, container, false);       return mView; } 

and continu your work based on that mView, so to find a View by id, call mView.findViewById(..);

for the FragmentActivity part:

the xml part "must" have a FrameLayout in order to inflate a fragment in it

        <FrameLayout             android:id="@+id/content_frame"             android:layout_width="match_parent"             android:layout_height="match_parent"  >         </FrameLayout> 

as for the inflation part

getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();

begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site

I ended up here after struggling for a while, but actually what I was missing was just:

If a #include file or one of its dependencies cannot be found, you can also click on the red squiggles under the include statements to view suggestions for how to update your configuration.
