Programs & Examples On #Nbehave

On Windows:

1. Add USER Environment variables:

NOTE: Path should be appended

JAVA_HOME           %ProgramFiles%\Android\Android Studio\jre
ANDROID_SDK_ROOT    %LocalAppData%\Android\Sdk
Path                %LocalAppData%\Android\Sdk

2. Run the below command to accept licenses:

NOTE: Accept all licenses (say y)

%ANDROID_SDK_ROOT%/tools/bin/sdkmanager.bat --licenses

3. Now run your app:

(like below, or another command that failed for you):

cd \myapp\
react-native run-android

push() adds a new element to the end of an array.
pop() removes an element from the end of an array.

unshift() adds a new element to the beginning of an array.
shift() removes an element from the beginning of an array.

To remove first element from an array arr , use arr.shift()
To remove last element from an array arr , use arr.pop()

strip is not limited to whitespace characters either:

# remove all leading/trailing commas, periods and hyphens
title = title.strip(',.-')

depending on who is going to be using your database, for example African names will do with varchar(20) for last name and first name separated. however it is different from nation to nation but for the sake saving your database resources and memory, separate last name and first name fields and use varchar(30) think that will work.

No.

Not even the very latest C99 standard supports this.

Here is yet another one-liner for you:

your_array.sort((a, b) => a.distance === b.distance ? 0 : a.distance > b.distance || -1);

If you want them to be really equal (i.e. the same items and the same number of each item), I think that the simplest solution is to sort before comparing:

Enumerable.SequenceEqual(list1.OrderBy(t => t), list2.OrderBy(t => t))

Edit:

Here is a solution that performs a bit better (about ten times faster), and only requires IEquatable, not IComparable:

public static bool ScrambledEquals<T>(IEnumerable<T> list1, IEnumerable<T> list2) {
  var cnt = new Dictionary<T, int>();
  foreach (T s in list1) {
    if (cnt.ContainsKey(s)) {
      cnt[s]++;
    } else {
      cnt.Add(s, 1);
    }
  }
  foreach (T s in list2) {
    if (cnt.ContainsKey(s)) {
      cnt[s]--;
    } else {
      return false;
    }
  }
  return cnt.Values.All(c => c == 0);
}

Edit 2:

To handle any data type as key (for example nullable types as Frank Tzanabetis pointed out), you can make a version that takes a comparer for the dictionary:

public static bool ScrambledEquals<T>(IEnumerable<T> list1, IEnumerable<T> list2, IEqualityComparer<T> comparer) {
  var cnt = new Dictionary<T, int>(comparer);
  ...

I ran into this error as well for a while. I think (hope) I've wrapped my head around it, wanted to write it here for reference.

When you add middleware to connect or express (which is built on connect) using the app.use method, you're appending items to Server.prototype.stack in connect (At least with the current npm install connect, which looks quite different from the one github as of this post). When the server gets a request, it iterates over the stack, calling the (request, response, next) method.

The problem is, if in one of the middleware items writes to the response body or headers (it looks like it's either/or for some reason), but doesn't call response.end() and you call next() then as the core Server.prototype.handle method completes, it's going to notice that:

1. there are no more items in the stack, and/or
2. that response.headerSent is true.

So, it throws an error. But the error it throws is just this basic response (from the connect http.js source code:

res.statusCode = 404;
res.setHeader('Content-Type', 'text/plain');
res.end('Cannot ' + req.method + ' ' + req.url);

Right there, it's calling res.setHeader('Content-Type', 'text/plain');, which you are likely to have set in your render method, without calling response.end(), something like:

response.setHeader("Content-Type", "text/html");
response.write("<p>Hello World</p>");

The way everything needs to be structured is like this:

Good Middleware

// middleware that does not modify the response body
var doesNotModifyBody = function(request, response, next) {
  request.params = {
    a: "b"
  };
  // calls next because it hasn't modified the header
  next();
};

// middleware that modify the response body
var doesModifyBody = function(request, response, next) {
  response.setHeader("Content-Type", "text/html");
  response.write("<p>Hello World</p>");
  response.end();
  // doesn't call next()
};

app.use(doesNotModifyBody);
app.use(doesModifyBody);

Problematic Middleware

var problemMiddleware = function(request, response, next) {
  response.setHeader("Content-Type", "text/html");
  response.write("<p>Hello World</p>");
  next();
};

The problematic middleware sets the response header without calling response.end() and calls next(), which confuses connect's server.

$("#datepicker").datepicker("option", "dateFormat", "yy-mm-dd ");

For the time picker, you should add timepicker to Datepicker, and it would be formatted with one equivalent command.

EDIT

Use this one that extend jQuery UI Datepicker. You can pick up both date and time.

You can use Oracle Data Dictionary to get information about oracle objects.

You can get list of tables in different ways:

select * 
from dba_tables

or for example:

select * 
from dba_objects 
where object_type = 'TABLE' 

Then you can get table columns using table name:

select * 
from dba_tab_columns

Then you can get list of dependencies (triggers, views and etc.):

select * 
from dba_dependencies
where referenced_type='TABLE' and referenced_name=:t_name 

Then you can get text source of this objects:

select * from dba_source

And you can use USER or ALL views instead of DBA if you want.

For Mac OS Users :

Go to your Android SDK folder and delete the tools folder (I recommend you to make a copy before deleting it, in case this solution does not solve the problem for you)

Then download the tools folder here :

http://dl-ssl.google.com/android/repository/tools_r25.2.5-macosx.zip

You can find all tools zip version here :

https://androidsdkoffline.blogspot.fr/p/android-sdk-build-tools.html

Then unzip the download file and place it in the Android sdk folder.

Hope it helps

Configuring this worked for me: -vmargs -Xms1536m -Xmx2048m -XX:MaxPermSize=1024m on Eclipse Java Photon June 2018

Running Windows 10, 8 GB ram and 64 bit. You can extend -Xmx2048 -XX:MaxpermSize= 1024m to 4096m too, if your computer has good ram.Mine worked well.

The path location must not contain á,à,â, and similars. Chinese characters or any other diferent than the usual alphabetical characters. For example, my path was C:\Users\Vinícius\AndroidStudioProjects\MyApplication .But my user name had the letter í. So I create a folder 'custom2222' and change the path to C:\custom2222\MyApplication

Try the following:

print "First is: %f" % (first)
print "Second is: %f" % (second)

I am unsure what answer is. But apart from that, this will be:

print "DONE: %f DIVIDED BY %f EQUALS %f, SWEET MATH BRO!" % (first, second, ans)

There's a lot of text on Format String Specifiers. You can google it and get a list of specifiers. One thing I forgot to note:

If you try this:

print "First is: %s" % (first)

It converts the float value in first to a string. So that would work as well.

How did you configure networking when you created the guest? The easiest way is to set the network adapter to NAT, if you don't need to access the vm from another pc.

Here is a version of Robert B's answer that works for List<T> and sorting by a specified String property of the object using Reflection and no 3rd party libraries

/**
 * Sorts a List by the specified String property name of the object.
 * 
 * @param list
 * @param propertyName
 */
public static <T> void sortList(List<T> list, final String propertyName) {

    if (list.size() > 0) {
        Collections.sort(list, new Comparator<T>() {
            @Override
            public int compare(final T object1, final T object2) {
                String property1 = (String)ReflectionUtils.getSpecifiedFieldValue (propertyName, object1);
                String property2 = (String)ReflectionUtils.getSpecifiedFieldValue (propertyName, object2);
                return property1.compareToIgnoreCase (property2);
            }
        });
    }
}


public static Object getSpecifiedFieldValue (String property, Object obj) {

    Object result = null;

    try {
        Class<?> objectClass = obj.getClass();
        Field objectField = getDeclaredField(property, objectClass);
        if (objectField!=null) {
            objectField.setAccessible(true);
            result = objectField.get(obj);
        }
    } catch (Exception e) {         
    }
    return result;
}

public static Field getDeclaredField(String fieldName, Class<?> type) {

    Field result = null;
    try {
        result = type.getDeclaredField(fieldName);
    } catch (Exception e) {
    }       

    if (result == null) {
        Class<?> superclass = type.getSuperclass();     
        if (superclass != null && !superclass.getName().equals("java.lang.Object")) {       
            return getDeclaredField(fieldName, type.getSuperclass());
        }
    }
    return result;
}

The query execution happens on all get methods like

$this->db->get('table_name');
$this->db->get_where('table_name',$array);

While last_query contains the last query which was run

$this->db->last_query();

If you want to get query string without execution you will have to do this. Go to system/database/DB_active_rec.php Remove public or protected keyword from these functions

public function _compile_select($select_override = FALSE)
public function _reset_select()

Now you can write query and get it in a variable

$this->db->select('trans_id');
$this->db->from('myTable');
$this->db->where('code','B');
$subQuery = $this->db->_compile_select();

Now reset query so if you want to write another query the object will be cleared.

$this->db->_reset_select();

And the thing is done. Cheers!!! Note : While using this way you must use

$this->db->from('myTable')

instead of

$this->db->get('myTable')

which runs the query.

Take a look at this example

Agreed with jcadcell comments, but had to use JDK 1.8 because my eclipse need that. So I just copied the MSVCR71.DLL from jdk1.6 and pasted into jdk1.8 in both the folder jdk1.8.0_121\bin and jdk1.8.0_121\jre\bin

and it Worked .... Wow... Thanks :)

For changing application name only (that will display along with app icon) in xcode 4 or later:

Click on your project file icon from Groups & Files panel, choose Target -> Build Settings -> Packaging -> Product Name. Click on the row, a pop-up will come, type your new app name here.

For changing Project name only (that will display along with project icon) in xcode 4 or later:

Click on your project file icon from Groups & Files panel, choose Project(above targets) from right pane, just see at the far right pane(it will be visible only if you have enabled "Hide or show utilities").Look for project name.Edit it to new name you want to give your project.

Delete your app from simulator/device, clean and run.Changes should reflect.

That's it

For me is better to have a schema that you can map directly to code (easy to automate), mainly because code is what is going to be at both ends.

GET  /orders          <---> orders 
POST /orders          <---> orders.push(data)
GET  /orders/1        <---> orders[1]
PUT  /orders/1        <---> orders[1] = data
GET  /orders/1/lines  <---> orders[1].lines
POST /orders/1/lines  <---> orders[1].lines.push(data) 

Afterall, you could edit the .vimrc,then add the conf

set tabstop=4

Or exec the command

Code ${1:-/dev/stdin} will just understand first argument, so, how about this.

ARGS='$*'
if [ -z "$*" ]; then
  ARGS='-'
fi
eval "cat -- $ARGS" | while read line
do
   echo "$line"
done

When you draw to a canvas element, you are simply drawing a bitmap in immediate mode.

The elements (shapes, lines, images) that are drawn have no representation besides the pixels they use and their colour.

Therefore, to get a click event on a canvas element (shape), you need to capture click events on the canvas HTML element and use some math to determine which element was clicked, provided you are storing the elements' width/height and x/y offset.

To add a click event to your canvas element, use...

canvas.addEventListener('click', function() { }, false);

To determine which element was clicked...

var elem = document.getElementById('myCanvas'),
    elemLeft = elem.offsetLeft + elem.clientLeft,
    elemTop = elem.offsetTop + elem.clientTop,
    context = elem.getContext('2d'),
    elements = [];

// Add event listener for `click` events.
elem.addEventListener('click', function(event) {
    var x = event.pageX - elemLeft,
        y = event.pageY - elemTop;

    // Collision detection between clicked offset and element.
    elements.forEach(function(element) {
        if (y > element.top && y < element.top + element.height 
            && x > element.left && x < element.left + element.width) {
            alert('clicked an element');
        }
    });

}, false);

// Add element.
elements.push({
    colour: '#05EFFF',
    width: 150,
    height: 100,
    top: 20,
    left: 15
});

// Render elements.
elements.forEach(function(element) {
    context.fillStyle = element.colour;
    context.fillRect(element.left, element.top, element.width, element.height);
});?

jsFiddle.

This code attaches a click event to the canvas element, and then pushes one shape (called an element in my code) to an elements array. You could add as many as you wish here.

The purpose of creating an array of objects is so we can query their properties later. After all the elements have been pushed onto the array, we loop through and render each one based on their properties.

When the click event is triggered, the code loops through the elements and determines if the click was over any of the elements in the elements array. If so, it fires an alert(), which could easily be modified to do something such as remove the array item, in which case you'd need a separate render function to update the canvas.

For completeness, why your attempts didn't work...

elem.onClick = alert("hello world"); // displays alert without clicking

This is assigning the return value of alert() to the onClick property of elem. It is immediately invoking the alert().

elem.onClick = alert('hello world');  // displays alert without clicking

In JavaScript, the ' and " are semantically identical, the lexer probably uses ['"] for quotes.

elem.onClick = "alert('hello world!')"; // does nothing, even with clicking

You are assigning a string to the onClick property of elem.

elem.onClick = function() { alert('hello world!'); }; // does nothing

JavaScript is case sensitive. The onclick property is the archaic method of attaching event handlers. It only allows one event to be attached with the property and the event can be lost when serialising the HTML.

elem.onClick = function() { alert("hello world!"); }; // does nothing

Again, ' === ".

For Apache 2 on Linux Mint 17.3 Cinnamon 64-bit, the following works:

1. In /etc/apache2/sites-available/ open the 000-default.conf file, and change the Document Root to the absolute path of your directory.

   sudo vim /etc/apache2/sites-available/000-default.conf

2. In folder /etc/apache2/ open file httpd.conf, and add a <Directory> tag referencing your directory and containing the exact same settings as the tag for var/www.

    sudo vim /etc/apache2/apache2.conf
   

   On my machine it looked like this:

   ---

    <Directory /home/my_user_name/php/>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
    </Directory>
   

Note: In the first step you probably want to change Document Root in the default-ssl.conf file as well for SSL purposes. But as far as I can tell, this isn't required to get a general development environment running.

SELECT date_part ('year', f) * 12

1) div id is not reusable and should only be applied to one element of HTML while div class can be added to multiple elements.

2) An id has greater importance if both are applied to the same element and have conflicting styles, the styles of the id will be applied.

3) Style element always refer a div class by putting a . (dot) in front of their names while div id class is referred by putting a # (hash) in front of their names.

4) Example :-

class in <style> declaration - .red-background { background-color: red; }

id in <style> declaration - #blue-background {background-color: blue;}

<div class="red-background" id="blue-background">Hello</div> Here background will be in blue color

Because the em (http://en.wikipedia.org/wiki/Em_(typography)) is directly proportional to the font size currently in use. If the font size is, say, 16 points, one em is 16 points. If your font size is 16 pixels (note: not the same as points), one em is 16 pixels.

This leads to two (related) things:

1. it's easy to keep proportions, if you choose to edit your font sizes in your CSS later on.
2. Many browsers support custom font sizes, overriding your CSS. If you design everything in pixels, your layout might break in these cases. But, if you use ems, these overridings should mitigate these problems.

With gradle, the project settings will be cleared whenever you refresh the gradle settings. Instead you need to add the following lines (or similar) in your build.gradle, I'm using kotlin so:

sourceSets {
    main {
        java {
            srcDir "${buildDir.absolutePath}/generated/source/kapt/main"
        }
    }
}

you are importing java.util package. That's why its giving error. there is a random() in java.util package too. Please remove the import statement importing java.util package. then your program will use random() method for java.lang by default and then your program will work. remember to cast it i.e

int x = (int)(Math.random()*100);

The answer from @Emiliano is excellent. You can also pass named parameters like so:

powershell.exe -Command 'G:\Karan\PowerShell_Scripts\START_DEV.ps1' -NamedParam1 "SomeDataA" -NamedParam2 "SomeData2"

Note the parameters are outside the command call, and you'll use:

[parameter(Mandatory=$false)]
  [string]$NamedParam1,
[parameter(Mandatory=$false)]
  [string]$NamedParam2

Because the bootstrap-select is a bootstrap component and therefore you need to include it in your code as you did for your V3

NOTE: this component only works in boostrap-4 since version 1.13.0

$('select').selectpicker();

Simply casting the string as an int won't work reliably. You need to convert it to an int32. For this you can use the .NET convert class and its ToInt32 method. The method requires a string ($strNum) as the main input, and the base number (10) for the number system to convert to. This is because you can not only convert to the decimal system (the 10 base number), but also to, for example, the binary system (base 2).

Give this method a try:

[string]$strNum = "1.500"
[int]$intNum = [convert]::ToInt32($strNum, 10)

$intNum

#import "YourViewController.h"

To push a view including the navigation bar and/or tab bar:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"YourStoryboard" bundle:nil];
YourViewController *viewController = (YourViewcontroller *)[storyboard instantiateViewControllerWithIdentifier:@"YourViewControllerIdentifier"];
[self.navigationController pushViewController:viewController animated:YES];

To set identifier to a view controller, Open YourStoryboard.storyboard. Select YourViewController View-> Utilities -> ShowIdentityInspector. There you can specify the identifier.

You can get that error if you have an object with the same name as the schema. For example:

create sequence s2;

begin
  s2.a;
end;
/

ORA-06550: line 2, column 6:
PLS-00302: component 'A' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored

When you refer to S2.MY_FUNC2 the object name is being resolved so it doesn't try to evaluate S2 as a schema name. When you just call it as MY_FUNC2 there is no confusion, so it works.

The documentation explains name resolution. The first piece of the qualified object name - S2 here - is evaluated as an object on the current schema before it is evaluated as a different schema.

It might not be a sequence; other objects can cause the same error. You can check for the existence of objects with the same name by querying the data dictionary.

select owner, object_type, object_name
from all_objects
where object_name = 'S2';

mysql> uninstall plugin validate_password;

A plugin can be disabled by configuration only if installed.

When using the sublime text editor, I was able to select the segment of my code that was giving me the inconsistent use of tabs and spaces in indentation error and select:

view > indentation > convert indentation to spaces

which resolved the issue for me.

you can use zscore to analyze the data in column C and D for outliers, where zscore is the series - series.mean / series.std(). Use apply too create a user defined function for difference between C and D creating a new resulting dataframe. Apply uses the group result set.

To execute easily a script file in the same folder (or subfolder of) as the caller you can use this:

# Get full path to the script:
$ScriptRoute = [System.IO.Path]::GetFullPath([System.IO.Path]::Combine($PSScriptRoot, "Scriptname.ps1"))

# Execute script at location:
&"$ScriptRoute"

Clojure can be used, but it's slow.

I do not like transformations to have any more info than needed. So instead of restating the keys, I simply state the condition and intention. It is much easier to see the intention when done like this, at least IMO. Also, I try and put all the xdt attributes first to indicate to the reader, these are transformations and not new things being defined.

<appSettings>
  <add xdt:Locator="Condition(@key='developmentModeUserId')" xdt:Transform="Remove" />
  <add xdt:Locator="Condition(@key='developmentMode')" xdt:Transform="SetAttributes"
       value="false"/>
</appSettings>

In the above it is much easier to see that the first one is removing the element. The 2nd one is setting attributes. It will set/replace any attributes you define here. In this case it will simply set value to false.

Here is my Solution, I think will better to use vh (viewport height) and vw for (viewport width), units regarding to the height and width of the current viewport

function myFunction() {
  var element = document.getElementById("main");
  element.classList.add("container");
}

.container{
  height: 100vh;
  width: 100vw;
  overflow: hidden;
  background-color: #333;
  margin: 0; 
  padding: 0; 
}

<div id="main"></div>
<button onclick="myFunction()">Try it</button>

The main difference between the web containers and application server is that most web containers such as Apache Tomcat implements only basic JSR like Servlet, JSP, JSTL wheres Application servers implements the entire Java EE Specification. Every application server contains web container.

Use vh attributes. It means viewport height and is a percentage. So height: 90vh would mean 90% of the viewport height. This works in most modern browsers.

Eg.

div {
  height: 90vh;
}

You can forego the rest of your silly 100% stuff on the body.

If you have a header you can also do some fun things like take it into account by using the calc function in CSS.

Eg.

div {
  height: calc(100vh - 50px);
}

This will give you 100% of the viewport height, minus 50px for your header.

I know this is an old thread but I thought I would chime in.

Chrome currently has a solution built in.

1. Use CTRL+SHIFT+I (or navigate to Current Page Control > Developer > Developer Tools. In the newer versions of Chrome, click the Wrench icon > Tools > Developer Tools.) to enable the Developer Tools.
2. From within the developer tools click on the Network button. If it isn't already, enable it for the session or always.
3. Click the "XHR" sub-button.
4. Initiate an AJAX call.
5. You will see items begin to show up in the left column under "Resources".
6. Click the resource and there are 2 tabs showing the headers and return content.

This is normally the case then the ID is not a natural part of the entity, but a database artifact that needs be abstracted away.

It is a design decision - to only allow setting the ID during construction or through method invocation, so it is managed internally by the class.

You can write a setter yourself, assuming you have a backing field:

private int Id = 0;
public void SetId (int id)
{
  this.Id = id;
}

Or through a constructor:

private int Id = 0;
public Person (int id)
{
  this.Id = id;
}

By changing one level in the "logging.config.dictConfig" you'll be able to take the whole logging level to a new level.

logging.config.dictConfig({
'version': 1,
'disable_existing_loggers': False,
'formatters': {
    'console': {
        'format': '%(name)-12s %(levelname)-8s %(message)s'
    },
    'file': {
        'format': '%(asctime)s %(name)-12s %(levelname)-8s %(message)s'
    }
},
'handlers': {
    'console': {
        'class': 'logging.StreamHandler',
        'formatter': 'console'
    },
#CHANGE below level from DEBUG to THE_LEVEL_YOU_WANT_TO_SWITCH_FOR
#if we jump from DEBUG to INFO
# we won't be able to see the DEBUG logs in our logging.log file
    'file': {
        'level': 'DEBUG',
        'class': 'logging.FileHandler',
        'formatter': 'file',
        'filename': 'logging.log'
    },
},
'loggers': {
    '': {
        'level': 'DEBUG',
        'handlers': ['console', 'file'],
        'propagate': False,
    },
}

})

For those interested in the details - you can see what's inside the public key file (generated as explained above), by doing this:-

openssl rsa -noout -text -inform PEM -in key.pub -pubin

or for the private key file, this:-

openssl rsa -noout -text -in key.private

which outputs as text on the console the actual components of the key (modulus, exponents, primes, ...)

-in php.ini (inside /etc/php.ini)

 max_input_time = 24000
 max_execution_time = 24000
 upload_max_filesize = 12000M
 post_max_size = 24000M
 memory_limit = 12000M

-in nginx.conf(inside /opt/nginx/conf)

client_max_body_size 24000M

Its working for my case

You can also do something like that:

<error-page>
    <error-code>403</error-code>
    <location>/403.html</location>
</error-page>

<error-page>
    <location>/error.html</location>
</error-page>

For error code 403 it will return the page 403.html, and for any other error code it will return the page error.html.

If you are trying to cache the tiles that Google serves, that may be a violation of Google's Terms of Service (unless, under certain circumstances, if you've purchased their enterprise Maps API Premier). That's why gmapcatcher has it crossed off their list. See http://code.google.com/p/gmapcatcher/issues/detail?id=210.

At the gmapcatcher URL above, you will also find a shell script that can download tiles (or so its author says).

There are also other projects that try to make Google Maps available offline:

http://code.google.com/p/ogmaps/

http://code.google.com/p/gmapoffline/

Lastly, if Google Earth can meet your needs, then you can use that. Offline usage of Google Earth requires a Google Earth Enterprise license according to http://www.google.com/permissions/geoguidelines.html.

Note that the preceding page also says: "You may not scrape or otherwise export Content from Google Maps or Earth or save it for offline use." So if you try to cache tiles, that will almost certainly be considered (by Google, anyway) a violation of the Terms of Service.

I use this

def cleaned( aFile ):
    for line in aFile:
        yield line.strip()

Then I can do things like this.

lines = list( cleaned( open("file","r") ) )

Or, I can extend cleaned with extra functions to, for example, drop blank lines or skip comment lines or whatever.

The ':' is a delimiter for key value pairs basically. In your example it is a Javascript Object Literal notation.

In javascript, Objects are defined with the colon delimiting the identifier for the property, and its value so you can have the following:

return { 
    Property1 : 125,
    Property2 : "something",
    Method1 : function() { /* do nothing */ },
    array: [5, 3, 6, 7]
};

and then use it like:

var o =  { 
    property1 : 125,
    property2 : "something",
    method1 : function() { /* do nothing */ },
    array: [5, 3, 6, 7]
};

alert(o.property1); // Will display "125"

A subset of this is also known as JSON (Javascript Object Notation) which is useful in AJAX calls because it is compact and quick to parse in server-side languages and Javascript can easily de-serialize a JSON string into an object.

// The parenthesis '(' & ')' around the object are important here
var o = eval('(' + "{key: \"value\"}" + ')');

You can also put the key inside quotes if it contains some sort of special character or spaces, but I wouldn't recommend that because it just makes things harder to work with.

Keep in mind that JavaScript Object Literal Notation in the JavaScript language is different from the JSON standard for message passing. The main difference between the 2 is that functions and constructors are not part of the JSON standard, but are allowed in JS object literals.

In your MakeFile or CMakeLists.txt you can set CMAKE_CXX_FLAGS as below:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -I/path/to/your/folder")

Another way to do it, with Java 8 and without external libs:

Stream.concat(collectionA.stream(), collectionB.stream())
      .collect(Collectors.toList())

Nothing compares to extjs in terms of community size and presence on StackOverflow. Despite previous controversy, Ext JS now has a GPLv3 open source license. Its learning curve is long, but it can be quite rewarding once learned. Ext JS lacks a Material Design theme, and the team has repeatedly refused to release the source code on GitHub. For mobile, one must use the separate Sencha Touch library.

Have in mind also that,

large JavaScript libraries, such as YUI, have been receiving less attention from the community. Many developers today look at large JavaScript libraries as walled gardens they don’t want to be locked into.

-- Announcement of YUI development being ceased

That said, below are a number of Ext JS alternatives currently available.

Leading client widget libraries

1. Blueprint is a React-based UI toolkit developed by big data analytics company Palantir in TypeScript, and "optimized for building complex data-dense interfaces for desktop applications". Actively developed on GitHub as of May 2019, with comprehensive documentation. Components range from simple (chips, toast, icons) to complex (tree, data table, tag input with autocomplete, date range picker. No accordion or resizer.

   Blueprint targets modern browsers (Chrome, Firefox, Safari, IE 11, and Microsoft Edge) and is licensed under a modified Apache license.

   Sandbox / demo • GitHub • Docs

2. Webix - an advanced, easy to learn, mobile-friendly, responsive and rich free&open source JavaScript UI components library. Webix spun off from DHTMLX Touch (a project with 8 years of development behind it - see below) and went on to become a standalone UI components framework. The GPL3 edition allows commercial use and lets non-GPL applications using Webix keep their license, e.g. MIT, via a license exemption for FLOSS. Webix has 55 UI widgets, including trees, grids, treegrids and charts. Funding comes from a commercial edition with some advanced widgets (Pivot, Scheduler, Kanban, org chart etc.). Webix has an extensive list of free and commercial widgets, and integrates with most popular frameworks (React, Vue, Meteor, etc) and UI components.

   

   Skins look modern, and include a Material Design theme. The Touch theme also looks quite Material Design-ish. See also the Skin Builder.

   Minimal GitHub presence, but includes the library code, and the documentation (which still needs major improvements). Webix suffers from a having a small team and a lack of marketing. However, they have been responsive to user feedback, both on GitHub and on their forum.

   The library was lean (128Kb gzip+minified for all 55 widgets as of ~2015), faster than ExtJS, dojo and others, and the design is pleasant-looking. The current version of Webix (v6, as of Nov 2018) got heavier (400 - 676kB minified but NOT gzipped).

   The demos on Webix.com look and function great. The developer, XB Software, uses Webix in solutions they build for paying customers, so there's likely a good, funded future ahead of it.

   Webix aims for backwards compatibility down to IE8, and as a result carries some technical debt.

3. react-md - MIT-licensed Material Design UI components library for React. Responsive, accessible. Implements components from simple (buttons, cards) to complex (sortable tables, autocomplete, tags input, calendars). One lead author, ~1900 GitHub stars.

4. kendo - jQuery-based UI toolkit with 40+ basic open-source widgets, plus commercial professional widgets (grids, trees, charts etc.). Responsive&mobile support. Works with Bootstrap and AngularJS. Modern, with Material Design themes. The documentation is available on GitHub, which has enabled numerous contributions from users (4500+ commits, 500+ PRs as of Jan 2015).

   

   Well-supported commercially, claiming millions of developers, and part of a large family of developer tools. Telerik has received many accolades, is a multi-national company (Bulgaria, US), was acquired by Progress Software, and is a thought leader.

   A Kendo UI Professional developer license costs $700 and posting access to most forums is conditioned upon having a license or being in the trial period.

   [Wikipedia] • GitHub/Telerik • Demos • Playground • Tools

5. OpenUI5 - jQuery-based UI framework with 180 widgets, Apache 2.0-licensed and fully-open sourced and funded by German software giant SAP SE.

   

   The community is much larger than that of Webix, SAP is hiring developers to grow OpenUI5, and they presented OpenUI5 at OSCON 2014.

   The desktop themes are rather lackluster, but the Fiori design for web and mobile looks clean and neat.

   Wikipedia • GitHub • Mobile-first controls demos • Desktop controls demos • SO

6. DHTMLX - JavaScript library for building rich Web and Mobile apps. Looks most like ExtJS - check the demos. Has been developed since 2005 but still looks modern. All components except TreeGrid are available under GPLv2 but advanced features for many components are only available in the commercial PRO edition - see for example the tree. Claims to be used by many Fortune 500 companies.

   

   Minimal presence on GitHub (the main library code is missing) and StackOverflow but active forum. The documentation is not available on GitHub, which makes it difficult to improve by the community.

7. Polymer, a Web Components polyfill, plus Polymer Paper, Google's implementation of the Material design. Aimed at web and mobile apps. Doesn't have advanced widgets like trees or even grids but the controls it provides are mobile-first and responsive. Used by many big players, e.g. IBM or USA Today.

   

8. Ant Design claims it is "a design language for background applications", influenced by "nature" and helping designers "create low-entropy atmosphere for developer team". That's probably a poor translation from Chinese for "UI components for enterprise web applications". It's a React UI library written in TypeScript, with many components, from simple (buttons, cards) to advanced (autocomplete, calendar, tag input, table).

   The project was born in China, is popular with Chinese companies, and parts of the documentation are available only in Chinese. Quite popular on GitHub, yet it makes the mistake of splitting the community into Chinese and English chat rooms. The design looks Material-ish, but fonts are small and the information looks lost in a see of whitespace.

9. PrimeUI - collection of 45+ rich widgets based on jQuery UI. Apache 2.0 license. Small GitHub community. 35 premium themes available.

10. qooxdoo - "a universal JavaScript framework with a coherent set of individual components", developed and funded by German hosting provider 1&1 (see the contributors, one of the world's largest hosting companies. GPL/EPL (a business-friendly license).

    Mobile themes look modern but desktop themes look old (gradients).

11. jQuery UI - easy to pick up; looks a bit dated; lacks advanced widgets. Of course, you can combine it with independent widgets for particular needs, e.g. trees or other UI components, but the same can be said for any other framework.

12. angular + Angular UI. While Angular is backed by Google, it's being radically revamped in the upcoming 2.0 version, and "users will need to get to grips with a new kind of architecture. It's also been confirmed that there will be no migration path from Angular 1.X to 2.0". Moreover, the consensus seems to be that Angular 2 won't really be ready for use until a year or two from now. Angular UI has relatively few widgets (no trees, for example).

13. DojoToolkit and their powerful Dijit set of widgets. Completely open-sourced and actively developed on GitHub, but development is now (Nov 2018) focused on the new dojo.io framework, which has very few basic widgets. BSD/AFL license. Development started in 2004 and the Dojo Foundation is being sponsored by IBM, Google, and others - see Wikipedia. 7500 questions here on SO.

    

    Themes look desktop-oriented and dated - see the theme tester in dijit. The official theme previewer is broken and only shows "Claro". A Bootstrap theme exists, which looks a lot like Bootstrap, but doesn't use Bootstrap classes. In Jan 2015, I started a thread on building a Material Design theme for Dojo, which got quite popular within the first hours. However, there are questions regarding building that theme for the current Dojo 1.10 vs. the next Dojo 2.0. The response to that thread shows an active and wide community, covering many time zones.

    Unfortunately, Dojo has fallen out of popularity and fewer companies appear to use it, despite having (had?) a strong foothold in the enterprise world. In 2009-2012, its learning curve was steep and the documentation needed improvements; while the documentation has substantially improved, it's unclear how easy it is to pick up Dojo nowadays.

    With a Material Design theme, Dojo (2.0?) might be the killer UI components framework.

Widgets - Demo Apps - Examples - GitHub

Full-stack frameworks

1. SproutCore - developed by Apple for web applications with native performance, handling large data sets on the client. Powers iCloud.com. Not intended for widgets.

2. Wakanda: aimed at business/enterprise web apps - see What is Wakanda?. Architecture:

   • Wakanda Server (server-side JavaScript (custom engine) + open-source NoSQL database)
   • desktop IDE and WYSIWYG editor for tables, forms, reports

   • Wakanda Application Framework (datasource layer + browser-based interface widgets) that helps with browser and device compatibility across desktop and mobile

     Wakanda is highly integrated, includes a ton of features out of the box, but has a very small GitHub community and SO presence.

3. Servoy - "a cross platform frontend development and deployment environment for SQL databases". Boasts a "full WYSIWIG (What You See Is What You Get) UI designer for HTML5 with built-in data-binding to back-end services", responsive design, support for HTML6 Web Components, Websockets and mobile platforms. Written in Java and generates JavaScript code using various JavaBeans.

4. SmartClient/SmartGWT - mobile and cross-browser HTML5 UI components combined with a Java server. Aimed at building powerful business apps - see demos.

5. Vaadin - full-stack Java/GWT + JavaScript/HTML3 web app framework

6. Backbase - portal software

7. Shiny - front-end library on top R, with visualization, layout and control widgets

8. ZKOSS: Java+jQuery+Bootstrap framework for building enterprise web and mobile apps.

CSS libraries + minimal widgets

These libraries don't implement complex widgets such as tables with sorting/filtering, autocompletes, or trees.

1. Bootstrap

2. Foundation for Apps - responsive front-end framework on top of AngularJS; more of a grid/layout/navigation library

3. UI Kit - similar to Bootstrap, with fewer widgets, but with official off-canvas.

Libraries using HTML Canvas

Using the canvas elements allows for complete control over the UI, and great cross-browser compatibility, but comes at the cost of missing native browser functionality, e.g. page search via Ctrl/Cmd+F.

There are two problems in your code:

• The property is called visibility and not visiblity.
• It is not a property of the element itself but of its .style property.

It's easy to fix. Simple replace this:

document.getElementById("remember").visiblity

with this:

document.getElementById("remember").style.visibility

Have you got the driver installed? If you go into Start > Settings > Control Panel > Administrative Tools and click the Data Sources, then select the Drivers tab your driver info should be registered there.

Failing that it may be easier to simply set up a DSN connection to test with.

You can define multiple connection strings of course and set-up a 'mode' for working on different machines.

Also there's ConnectionStrings.com.

-- EDIT --

Just to further this, I found this thread on another site.

For my case I was getting that error when I was using async function on my server-side to fetch documents using mongoose. It turned out that the reason was I forgot to put await before calling find({}) method. Adding that part fixed my issue.

You could also try a pre/post checkout hook might do the trick.

ls -lR is to display all files, directories and sub directories of the current directory ls -lR | more is used to show all the files in a flow.

The best solution to me is to create a client service that you'll instantiate with your token an use it to wrap axios.

import axios from 'axios';

const client = (token = null) => {
    const defaultOptions = {
        headers: {
            Authorization: token ? `Token ${token}` : '',
        },
    };

    return {
        get: (url, options = {}) => axios.get(url, { ...defaultOptions, ...options }),
        post: (url, data, options = {}) => axios.post(url, data, { ...defaultOptions, ...options }),
        put: (url, data, options = {}) => axios.put(url, data, { ...defaultOptions, ...options }),
        delete: (url, options = {}) => axios.delete(url, { ...defaultOptions, ...options }),
    };
};

const request = client('MY SECRET TOKEN');

request.get(PAGES_URL);

In this client, you can also retrieve the token from the localStorage / cookie, as you want.

1. Go to File > Preference > Settings then
2. type: run code and scroll down until you see code-runner: Run in terminal, There will be multiple options called "code-runner". In that you can find the option mentioned below.
3. just check "Whether to run code in integrated terminal" and
4. restart vscode.

For Mac users, it is Code > Preference > Settings.

dynamic myDynamic = new { PropertyOne = true, PropertyTwo = false};

By default, SQL Plus treats '&' as a special character that begins a substitution string. This can cause problems when running scripts that happen to include '&' for other reasons:

SQL> insert into customers (customer_name) values ('Marks & Spencers Ltd');
Enter value for spencers: 
old   1: insert into customers (customer_name) values ('Marks & Spencers Ltd')
new   1: insert into customers (customer_name) values ('Marks  Ltd')

1 row created.

SQL> select customer_name from customers;

CUSTOMER_NAME
------------------------------
Marks  Ltd

If you know your script includes (or may include) data containing '&' characters, and you do not want the substitution behaviour as above, then use set define off to switch off the behaviour while running the script:

SQL> set define off
SQL> insert into customers (customer_name) values ('Marks & Spencers Ltd');

1 row created.

SQL> select customer_name from customers;

CUSTOMER_NAME
------------------------------
Marks & Spencers Ltd

You might want to add set define on at the end of the script to restore the default behaviour.

In case of building the heap, we start from height, logn -1 (where logn is the height of tree of n elements). For each element present at height 'h', we go at max upto (logn -h) height down.

    So total number of traversal would be:-
    T(n) = sigma((2^(logn-h))*h) where h varies from 1 to logn
    T(n) = n((1/2)+(2/4)+(3/8)+.....+(logn/(2^logn)))
    T(n) = n*(sigma(x/(2^x))) where x varies from 1 to logn
     and according to the [sources][1]
    function in the bracket approaches to 2 at infinity.
    Hence T(n) ~ O(n)

The server_name^docs directive is used to identify virtual hosts, they're not used to set the binding.

netstat tells you that nginx listens on 0.0.0.0:80 which means that it will accept connections from any IP.

If you want to change the IP nginx binds on, you have to change the listen^docs rule.
So, if you want to set nginx to bind to localhost, you'd change that to:

listen 127.0.0.1:80;

In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).

Look into the httpd.conf and/or httpd-vhosts.conf files and search for the DocumentRoot entry. If you configure multiple virtual hosts, there may be more than one of those, separated in <VirtualHost> tags.

Try below:

let image = UIImage(named: "ImageName.png") as UIImage
var button   = UIButton.buttonWithType(UIButtonType.System) as UIButton
button.frame = CGRectMake(100, 100, 100, 100)
button .setBackgroundImage(image, forState: UIControlState.Normal)
button.addTarget(self, action: "Action:", forControlEvents:UIControlEvents.TouchUpInside)
menuView.addSubview(button)

Let me know whether if it works or not?

You wouldn't have to put it in the button click hander. If you were, then you'd assign your text box a name (x:Name) in your view and then use the generated member of the same name in the code behind to set the Text property.

If you were avoiding code behind, then you would investigate the MVVM design pattern and data binding, and bind a property on your view model to the text box's Text property.

Some of these are lovely, but it can be done much more simply:

start = 0 # some starting index
end = 5000 # some ending index
filename = 'test.txt' # some file we want to use

with open(filename) as fh:
    data = fin.readlines()[start:end]

print(data)

That will use simply list slicing, it loads the whole file, but most systems will minimise memory usage appropriately, it's faster than most of the methods given above, and works on my 10G+ data files. Good luck!

In most cases it could be better to pad the columns only on the right so just the spacing between the columns gets padded, and the first column is still aligned with the table.

CSS:

.padding-table-columns td
{
    padding:0 5px 0 0; /* Only right padding*/
}

HTML:

<table className="padding-table-columns">
  <tr>
    <td>Cell one</td>
     <!-- There will be a 5px space here-->
    <td>Cell two</td>
     <!-- There will be an invisible 5px space here-->
  </tr>
</table>

int rgb = new Color(r, g, b).getRGB();

First add your item to mItems and then use:

mAdapter.notifyItemInserted(mItems.size() - 1);

this method is better than using:

mAdapter.notifyDataSetChanged();

in performance.

the following is that the difference between iterator and listIterator

iterator :

boolean hasNext();
E next();
void remove();

listIterator:

boolean hasNext();
E next();
boolean hasPrevious();
E previous();
int nextIndex();
int previousIndex();
void remove();
void set(E e);
void add(E e);

I wouldn't recommend this, but if you're really into it being one line and only writing 0 once, you can also do this:

int row, column, index = row = column = 0;

This means a class is redundantly mentioned with a class function. Try removing JSONDeserializer::

Well 'Abstract Interface' is a Lexical construct: http://en.wikipedia.org/wiki/Lexical_analysis.

It is required by the compiler, you could also write interface.

Well don't get too much into Lexical construct of the language as they might have put it there to resolve some compilation ambiguity which is termed as special cases during compiling process or for some backward compatibility, try to focus on core Lexical construct.

The essence of `interface is to capture some abstract concept (idea/thought/higher order thinking etc) whose implementation may vary ... that is, there may be multiple implementation.

An Interface is a pure abstract data type that represents the features of the Object it is capturing or representing.

Features can be represented by space or by time. When they are represented by space (memory storage) it means that your concrete class will implement a field and method/methods that will operate on that field or by time which means that the task of implementing the feature is purely computational (requires more cpu clocks for processing) so you have a trade off between space and time for feature implementation.

If your concrete class does not implement all features it again becomes abstract because you have a implementation of your thought or idea or abstractness but it is not complete , you specify it by abstract class.

A concrete class will be a class/set of classes which will fully capture the abstractness you are trying to capture class XYZ.

So the Pattern is

Interface--->Abstract class/Abstract classes(depends)-->Concrete class

Yes:

RelativeLayout.LayoutParams params= new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,ViewGroup.LayoutParams.WRAP_CONTENT); 
params.addRule(RelativeLayout.BELOW, R.id.below_id);
viewToLayout.setLayoutParams(params);

First, the code creates a new layout params by specifying the height and width. The addRule method adds the equivalent of the xml properly android:layout_below. Then you just call View#setLayoutParams on the view you want to have those params.

<?php
    $arr = array(3 => "Apple", 5 => "Ball", 11 => "Cat");
    echo array_values($arr)[0]; // Outputs: Apple
?>

Other Example:

<?php
    $arr = array(3 => "Apple", 5 => "Ball", 11 => "Cat");
    echo current($arr); // Outputs: Apple
    echo reset($arr); // Outputs: Apple
    echo next($arr); // Outputs: Ball
    echo current($arr); // Outputs: Ball
    echo reset($arr); // Outputs: Apple
?>

It may be effective to assign to the events 'touchstart mousedown' or 'touchend mouseup' to avoid undesired side-effects of using click.

If you are at a certain branch mybranch, just go ahead and git checkout commit_hash. Then you can return to your branch by git checkout mybranch. I had the same game bisecting a bug today :) Also, you should know about git bisect.

The part about not being able to use the Back button is a common misinterpretation. window.location.replace(URL) throws out the top ONE entry from the page history list, by overwriting it with the new entry, so the user can't easily go Back to that ONE particular webpage. The function does NOT wipe out the entire page history list, nor does it make the Back button completely non-functional.

(NO function nor combination of parameters that I know of can change or overwrite history list entries that you don't own absolutely for certain - browsers generally impelement this security limitation by simply not even defining any operation that might at all affect any entry other than the top one in the page history list. I shudder to think what sorts of dastardly things malware might do if such a function existed.)

If you really want to make the Back button non-functional (probably not "user friendly": think again if that's really what you want to do), "open" a brand new window. (You can "open" a popup that doesn't even have a "Back" button too ...but popups aren't very popular these days:-) If you want to keep your page showing no matter what the user does (again the "user friendliness" is questionable), set up a window.onunload handler that just reloads your page all over again clear from the very beginning every time.

Put them into a list and use merge with Reduce

Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
#    id v1 v2 v3
# 1   1  1 NA NA
# 2  10  4 NA NA
# 3   2  3  4 NA
# 4  43  5 NA NA
# 5  73  2 NA NA
# 6  23 NA  2  1
# 7  57 NA  3 NA
# 8  62 NA  5  2
# 9   7 NA  1 NA
# 10 96 NA  6 NA

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

Since we have a virtual address space of 2^32 and each page size is 2^12, we can store (2^32/2^12) = 2^20 pages. Since each entry into this page table has an address of size 4 bytes, then we have 2^20*4 = 4MB. So the page table takes up 4MB in memory.

The most complete (and correct) way of doing this would be, I believe:

if (old_key !== new_key) {
    Object.defineProperty(o, new_key,
        Object.getOwnPropertyDescriptor(o, old_key));
    delete o[old_key];
}

This method ensures that the renamed property behaves identically to the original one.

Also, it seems to me that the possibility to wrap this into a function/method and put it into Object.prototype is irrelevant regarding your question.

I found a way to check whether the input given is an integer or not using atoi() function .

Read the input as a string, and use atoi() function to convert the string in to an integer.

atoi() function returns the integer number if the input string contains integer, else it will return 0. You can check the return value of the atoi() function to know whether the input given is an integer or not.

There are lot more functions to convert a string into long, double etc., Check the standard library "stdlib.h" for more.

Note : It works only for non-zero numbers.

#include<stdio.h>
#include<stdlib.h>

int main() {
    char *string;
    int number;

    printf("Enter a number :");
    string = scanf("%s", string);

    number = atoi(string);

    if(number != 0)
        printf("The number is %d\n", number);
    else
        printf("Not a number !!!\n");
    return 0;
}

You are returning a reference to ret which is a variable on the stack.

You could use absolute positioning to pin the footer to the base of the parent div. I have also added 10px padding-bottom to the wrap (match the height of the footer). The absolute positioning is relative to the parent div rather than outside of the flow since you have already given it the position relative attribute.

body{ height:20000px }
#wrapper {padding:10%;}
#wrap{ 
    float: left;
    padding-bottom: 10px;
    position: relative;
    width: 40%; 
    background:#ccc; 
}
#fixed{ 
    position:absolute;
    width:100%;
    left: 0;
    bottom: 0;
    padding:0px;
    height:10px;
    background-color:#333;

}

I was getting this error when running a remote development development machine using Vagrant. None of the above solutions worked because all the files had the correct permissions.

I fixed it by changing config.vm.box = "hasicorp/bionic64" to config.vm.box = "bento/ubuntu-20.10".

This should do the trick

Sometimes we may not have access to a Jenkins machine to copy a folder directly into another Jenkins instance. So I wrote a menu driven utility which uses Jenkins REST API calls to install plugins and jobs from one Jenkins instance to another.

For plugin migration:

1. GET request: {SOURCE_JENKINS_SERVER}/pluginManager/api/json?depth=1 will get you the list of plugins installed with their version.

2. You can send a POST request with the following parameters to install these plugins.

   final_url=`{DESTINATION_JENKINS_SERVER}/pluginManager/installNecessaryPlugins`
   
   data=`<jenkins><install plugin="{PLUGIN_NAME}@latest"/></jenkins>` (where, latest will fetch the latest version of the plugin_name)
   
   auth=`(destination_jenkins_username, destination_jenkins_password)`
   
   header=`{crumb_field:crumb_value,"Content-Type":"application/xml”}` (where crumb_field=Jenkins-Crumb and get crumb value using API call {DESTINATION_JENKINS_SERVER}/crumbIssuer/api/json
   

For job migration:

1. You can get the list of jobs installed on {SOURCE_JENKINS_URL} using a REST call, {SOURCE_JENKINS_URL}/view/All/api/json
2. Then you can get each job config.xml file from the jobs on {SOURCE_JENKINS_URL} using the job URL {SOURCE_JENKINS_URL}/job/{JOB_NAME}.
3. Use this config.xml file to POST the content of the XML file on {DESTINATION_JENKINS_URL} and that will create a job on {DESTINATION_JENKINS_URL}.

I have created a menu-driven utility in Python which asks the user to start plugin or Jenkins migration and uses Jenkins REST API calls to do it.

You can refer the JenkinsMigration.docx from this URL jenkinsjenkinsmigrationjenkinsrestapi

Unicode string handling is already standardized in Python 3.

1. char's are already stored in Unicode (32-bit) in memory

2. You only need to open file in utf-8

How do I have to do in Python for calling an static method from another static method of the same class?

class Test() :
    @staticmethod
    def static_method_to_call()
        pass

    @staticmethod
    def another_static_method() :
        Test.static_method_to_call()

    @classmethod
    def another_class_method(cls) :
        cls.static_method_to_call()

var my_arr = new Array(listingID, site_click, browser, dimension);
    var AjaxURL = 'http://example.com';
    var jsonString = JSON.stringify(my_arr);
    $.ajax({
        type: "POST",
        url: AjaxURL,
        data: {data: jsonString},
        success: function(result) {
            window.console.log('Successful');
        }
    });

This has been working for me for quite some time.

WhatsApp is now providing a much simpler API https://wa.me/ This isn't introducing any new features, just a simpler way to execute things. There's no need to check for user agent while implementing this API as it will also work with native apps as well as the web interface of whatsapp (web.whatsapp.com) on desktop.

This can be used in multiple use cases

• A Click to chat button : Use https://wa.me/whatsappphonenumber to open a chat dialog with the specified whatsapp user. Please note that the whatsappphonenumber should be a valid whatsapp number in international format without leading zeros, '+', '-' and spaces. e.g. 15551234567

  <a href="https://wa.me/15551234567">Whatsapp Me</a>

• A Share this on whatsapp button : Use https://wa.me/?text=urlencodedtext to open a whatsapp contact selection dialog with a preset text. e.g.

  <a href="https://wa.me/?text=I%20found%20a%20great%20website.%20Check%20out%20this%20link%20https%3A%2F%2Fwww.example.com%2F">Share on WhatsApp</a>

• A Contact me button with prefilled text : A combination of the above two, Might be useful if you want to get a prefilled custom message from users landing on a particular page. Use format https://wa.me/whatsappphonenumber/?text=urlencodedtext

  <a href="https://wa.me/15551234567?text=I%20am%20interested%20in%20your%20services.%20How%20to%20get%20started%3F">I am interested</a>

Just found out that with the Java NIO (java.nio.file.*) you can easily write:

List<String> lines=Files.readAllLines(Paths.get("/tmp/test.csv"), StandardCharsets.UTF_8);
for(String line:lines){
  System.out.println(line);
}

instead of dealing with FileInputStreams and BufferedReaders...

Dont work for me, need to put scope in plural

validates_uniqueness_of :teacher_id, :scopes => [:semester_id, :class_id]

Maybe worth looking at QRGen, which is built on top of ZXing and supports UTF-8 with this kind of syntax:

// if using special characters don't forget to supply the encoding
VCard johnSpecial = new VCard("Jöhn D?e")
                        .setAdress("ëåäö? Sträät 1, 1234 Döestüwn");
QRCode.from(johnSpecial).withCharset("UTF-8").file();

Since the OP asked about CPU usage AND memory usage (accepted answer only shows technique to get cpu usage), I'd like to recommend the ActivityManager class and specifically the accepted answer from this question: How to get current memory usage in android?

I tried using this example but it failed miserably. Every time I use to invoke finish()/ finishactivity() inside a handler, I end up with this menacing java.lang.IllegalAccess Exception. i'm not sure how did it work for the one who posed the question.

Instead the solution I found was that create a method in your activity such as

void kill_activity()
{ 
    finish();
}

Invoke this method from inside the run method of the handler. This worked like a charm for me. Hope this helps anyone struggling with "how to close an activity from a different thread?".

Sometimes you really want to set the axes limits before you plot the data. In that case, you can set the "autoscaling" feature of the Axes or AxesSubplot object. The functions of interest are set_autoscale_on, set_autoscalex_on, and set_autoscaley_on.

In your case, you want to freeze the y axis' limits, but allow the x axis to expand to accommodate your data. Therefore, you want to change the autoscaley_on property to False. Here is a modified version of the FFT subplot snippet from your code:

fft_axes = pylab.subplot(h,w,2)
pylab.title("FFT")
fft = scipy.fft(rawsignal)
pylab.ylim([0,1000])
fft_axes.set_autoscaley_on(False)
pylab.plot(abs(fft))

The command is gradle dependencies, and its output is much improved in Gradle 1.2. (You can already try 1.2-rc-1 today.)

VMDK/VMX are VMWare file formats but you can use it with VirtualBox:

1. Create a new Virtual Machine and when asks for a hard disk choose "Use an existing hard disk"
2. Click on the "button with folder and green arrow image on the combo box right" which opens Virtual Media Manager, it looks like this (you can open it directly pressing CTRL+D on main window or in File > Virtual Media Manager menu)...
3. Then you can add the VMDK/VMX hard disk image and setup it for your virtual machine :)

Since the question was labeled with Github, adding another remote like https_origin and add the https connection can force you always to enter the password:

git remote add https_origin https://github.com/.../...

Install NPM uuid package (sources: https://github.com/kelektiv/node-uuid):

npm install uuid

and use it in your code:

var uuid = require('uuid');

Then create some ids ...

// Generate a v1 (time-based) id
uuid.v1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a'

// Generate a v4 (random) id
uuid.v4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1'

** UPDATE 3.1.0
The above usage is deprecated, so use this package like this:

const uuidv1 = require('uuid/v1');
uuidv1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a' 

const uuidv4 = require('uuid/v4');
uuidv4(); // -> '110ec58a-a0f2-4ac4-8393-c866d813b8d1' 

** UPDATE 7.x
And now the above usage is deprecated as well, so use this package like this:

const { v1: uuidv1 } = require('uuid');
uuidv1(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a' 

const { v4: uuidv4 } = require('uuid');
uuidv4(); // -> '6c84fb90-12c4-11e1-840d-7b25c5ee775a' 

try this on google search (or click here)

255 * .2 to hex

it will generate 0x33 as a result.

However, google does not round off values so you can only use 1-digit multipliers. if you want to use say .85, you have to get the rounded-off value of 255 * .85 first, then type (rounded-value here) to hex in google search.

You should use sum:

Total = df['MyColumn'].sum()
print (Total)
319

Then you use loc with Series, in that case the index should be set as the same as the specific column you need to sum:

df.loc['Total'] = pd.Series(df['MyColumn'].sum(), index = ['MyColumn'])
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

because if you pass scalar, the values of all rows will be filled:

df.loc['Total'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A        84   13.0   69.0
1        B        76   77.0  127.0
2        C        28   69.0   16.0
3        D        28   28.0   31.0
4        E        19   20.0   85.0
5        F        84  193.0   70.0
Total  319       319  319.0  319.0

Two other solutions are with at, and ix see the applications below:

df.at['Total', 'MyColumn'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

df.ix['Total', 'MyColumn'] = df['MyColumn'].sum()
print (df)
         X  MyColumn      Y      Z
0        A      84.0   13.0   69.0
1        B      76.0   77.0  127.0
2        C      28.0   69.0   16.0
3        D      28.0   28.0   31.0
4        E      19.0   20.0   85.0
5        F      84.0  193.0   70.0
Total  NaN     319.0    NaN    NaN

Note: Since Pandas v0.20, ix has been deprecated. Use loc or iloc instead.

I think the code below

If you want to use Arrays, it's pretty simple.

logs = gson.fromJson(br, JsonLog[].class); // line 6

Provide the JsonLog as an array JsonLog[].class

The :: are used to dereference scopes.

const int x = 5;

namespace foo {
  const int x = 0;
}

int bar() {
  int x = 1;
  return x;
}

struct Meh {
  static const int x = 2;
}

int main() {
  std::cout << x; // => 5
  {
    int x = 4;
    std::cout << x; // => 4
    std::cout << ::x; // => 5, this one looks for x outside the current scope
  }
  std::cout << Meh::x; // => 2, use the definition of x inside the scope of Meh
  std::cout << foo::x; // => 0, use the definition of x inside foo
  std::cout << bar(); // => 1, use the definition of x inside bar (returned by bar)
}

unrelated: cout and cin are not functions, but instances of stream objects.

This code is work perfect for me

Bitmap tempbg = BitmapFactory.decodeResource(getResources(),R.drawable.b1); //Load a background.
Bitmap final_Bitmap = BlurImage(tempbg);


@SuppressLint("NewApi")
Bitmap BlurImage (Bitmap input)
{
    try
    {
    RenderScript  rsScript = RenderScript.create(getApplicationContext());
    Allocation alloc = Allocation.createFromBitmap(rsScript, input);

    ScriptIntrinsicBlur blur = ScriptIntrinsicBlur.create(rsScript,   Element.U8_4(rsScript));
    blur.setRadius(21);
    blur.setInput(alloc);

    Bitmap result = Bitmap.createBitmap(input.getWidth(), input.getHeight(), Bitmap.Config.ARGB_8888);
    Allocation outAlloc = Allocation.createFromBitmap(rsScript, result);

    blur.forEach(outAlloc);
    outAlloc.copyTo(result);

    rsScript.destroy();
    return result;
    }
    catch (Exception e) {
        // TODO: handle exception
        return input;
    }

}

Most answers above will prevent users from adding new lines in a textarea field. If this is something you want to avoid, you can exclude this particular case by checking which element currently has focus :

var keyCode = e.keyCode || e.which;
if (keyCode === 13 && !$(document.activeElement).is('textarea')) {
  e.preventDefault();
  return false;
}

If you are looking for solution without using Java String functionality (i.e. split, match, etc.) then the following should help:

List<String> splitString(String string) {
        List<String> list = new ArrayList<String>();
        String token = "";
        char curr;
        for (int e = 0; e < string.length() + 1; e++) {
            if (e == 0)
                curr = string.charAt(0);
            else {
                curr = string.charAt(--e);
            }

            if (isNumber(curr)) {
                while (e < string.length() && isNumber(string.charAt(e))) {
                    token += string.charAt(e++);
                }
                list.add(token);
                token = "";
            } else {
                while (e < string.length() && !isNumber(string.charAt(e))) {
                    token += string.charAt(e++);
                }
                list.add(token);
                token = "";
            }

        }

        return list;
    }

boolean isNumber(char c) {
        return c >= '0' && c <= '9';
    }

This solution will split numbers and 'words', where 'words' are strings that don't contain numbers. However, if you like to have only 'words' containing English letters then you can easily modify it by adding more conditions (like isNumber method call) depending on your requirements (for example you may wish to skip words that contain non English letters). Also note that the splitString method returns ArrayList which later can be converted to String array.

calling select will result is lazy evaluation: for example:

val df1 = df.select("col1")
val df2 = df1.filter("col1 == 3")

both above statements create lazy path that will be executed when you call action on that df, such as show, collect etc.

val df3 = df2.collect()

Nimgoble's is the version I used in 2015. Thought I'd put it here as this question was top of the list in google for "wpf autocomplete textbox"

1. Install nuget package for project in Visual Studio

2. Add a reference to the library in the xaml:
   xmlns:behaviors="clr-namespace:WPFTextBoxAutoComplete;assembly=WPFTextBoxAutoComplete"

3. Create a textbox and bind the AutoCompleteBehaviour to List<String> (TestItems):
   <TextBox Text="{Binding TestText, UpdateSourceTrigger=PropertyChanged}" behaviors:AutoCompleteBehavior.AutoCompleteItemsSource="{Binding TestItems}" />

IMHO this is much easier to get started and manage than the other options listed above.

You can also use:

{{ word|striptags('<b>')|raw }}

so that only <b> tag will be allowed.

This solution worked for me:

<body onload="setTimeout(function() { document.myform.submit() }, 5000)">
   <form action=TripRecorder name="myform">
      <textarea id="result1"  name="res1" value="str1" cols="20" rows="1" ></textarea> <br> <br/>
      <textarea id="result2" name="res2" value="str2" cols="20" rows="1" ></textarea>
   </form>
</body>

You should create an App.config file (very similar to web.config).

You should right click on your project, add new item, and choose new "Application Configuration File".

Ensure that you add using System.Configuration in your project.

Then you can add values to it:

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <appSettings>
    <add key="setting1" value="key"/>
  </appSettings>
  <connectionStrings>
    <add name="prod" connectionString="YourConnectionString"/>
  </connectionStrings>
</configuration>

    private void Form1_Load(object sender, EventArgs e)
    {
        string setting = ConfigurationManager.AppSettings["setting1"];
        string conn = ConfigurationManager.ConnectionStrings["prod"].ConnectionString;
    }

Just a note: According to Microsoft, you should use ConfigurationManager instead of ConfigurationSettings (see the remarks section):

"The ConfigurationSettings class provides backward compatibility only. For new applications you should use the ConfigurationManager class or WebConfigurationManager class instead. "

One more thing that I would definitely like to highlight as logit is just a raw output, generally the output of last layer. This can be a negative value as well. If we use it as it's for "cross entropy" evaluation as mentioned below:

-tf.reduce_sum(y_true * tf.log(logits))

then it wont work. As log of -ve is not defined. So using o softmax activation, will overcome this problem.

This is my understanding, please correct me if Im wrong.

Configure static ip for your laptop and raspberry pi. On the rapberryPI configure it as following.

pi@rpi>sudo nano /etc/network/interfaces

Then configure following as required to connect to your laptop.

iface eth0 inet static

address 192.168.1.81

netmask 255.255.255.0

broadcast 192.168.1.255

mainJSON.getJSONArray("source") returns a JSONArray, hence you can remove the new JSONArray.

The JSONArray contructor with an object parameter expects it to be a Collection or Array (not JSONArray)

Try this:

JSONArray jsonMainArr = mainJSON.getJSONArray("source"); 

No problem. Just use the following. This will behave exactly like serializing a form but using a div's content instead.

$('#divId :input').serialize();

Here Blank mean what you are meaning.
A line contains full of whitespaces or a line contains nothing.
If you want to match a line which contains nothing then use '/^$/'.

You can use this command:

start /min iexplore http://www.google.com

With the use of /min, it will hit on the URL without opening in the browser.

Bewaaaaare of Gson! It's very cool, very great, but the second you want to do anything other than simple objects, you could easily need to start building your own serializers (which isn't that hard).

Also, if you have an array of Objects, and you deserialize some json into that array of Objects, the true types are LOST! The full objects won't even be copied! Use XStream.. Which, if using the jsondriver and setting the proper settings, will encode ugly types into the actual json, so that you don't loose anything. A small price to pay (ugly json) for true serialization.

Note that Jackson fixes these issues, and is faster than GSON.

Use the Task manager to find the Service and kill it from there using End Task. Always does the trick for me.

If you have made the service yourself, consider removing Long running operations from the OnStart event, usually that is what causes the Service to be non responsive.

I believe this is much simpler;

dynamic obj = JObject.Parse(jsonString);
string results  = obj.results;
foreach(string result in result.Split('))
{
//Todo
}

Try this:

$("#Search_Result").load("AJAX-Search.aspx?q=" + $("#q").val() + "&rnd=" + String((new Date()).getTime()).replace(/\D/gi, ''));

It works fine when i used it.

i think that is the solution

h:button - clicking on a h:button issues a bookmarkable GET request.

h:commandbutton - Instead of a get request, h:commandbutton issues a POST request which sends the form data back to the server.

Stringifying a null value in ActionScript will give the string "NULL". My suspicion is that someone has decided that it is, therefore, a good idea to decode the string "NULL" as null, causing the breakage you see here -- probably because they were passing in null objects and getting strings in the database, when they didn't want that (so be sure to check for that kind of bug, too).

For those that want a nice conditional:

DECLARE @MyDate DATETIME  = 'some date in future' --example  DateAdd(day,5,GetDate())

IF @MyDate < DATEADD(DAY,1,GETDATE())
    BEGIN
        PRINT 'Date NOT greater than today...'
END
ELSE 
    BEGIN
       PRINT 'Date greater than today...'
END 

I think you can find the answer you want in these two posts. They are mentioning Flash Builder, but essentially, the talk is about its Eclipse base.

Clear improperly cached compile errors in FlexBuilder: http://blog.aherrman.com/2010/05/clear-improperly-cached-compile-errors.html

How to fix Flash Builder broken workspace: http://va.lent.in/how-to-fix-flash-builder-broken-workspace/

It's incorrect, but you can try this instead:

select
    a.x,
    ( select b.y from b where b.v = a.v) as by,
    ( select b.z from b where b.v = a.v) as bz
from a

you can also use subquery in join

 select
        a.x,
        b.y,
        b.z
    from a
    left join (select y,z from b where ... ) b on b.v = a.v

or

   select
        a.x,
        b.y,
        b.z
    from a
    left join b on b.v = a.v

^{(ansible 2.9.6 ansible-lint 4.2.0)}

See ansible-lint default rules. The condition below causes E602 Don’t compare to empty string

    when: test_myscript.stderr != ""

Correct syntax and also "Ansible Galaxy Warning-Free" option is

    when: test_myscript.stderr | length > 0

Quoting from source code

"Use when: var|length > 0 rather than when: var != "" (or ' 'conversely when: var|length == 0 rather than when: var == "")"

Notes

1. Test empty bare variable e.g.

    - debug:
        msg: "Empty string '{{ var }}' evaluates to False"
      when: not var
      vars:
        var: ''

    - debug:
        msg: "Empty list {{ var }} evaluates to False"
      when: not var
      vars:
        var: []

give

    "msg": "Empty string '' evaluates to False"
    "msg": "Empty list [] evaluates to False"

2. But, testing non-empty bare variable string depends on CONDITIONAL_BARE_VARS. Setting ANSIBLE_CONDITIONAL_BARE_VARS=false the condition works fine but setting ANSIBLE_CONDITIONAL_BARE_VARS=true the condition will fail

    - debug:
        msg: "String '{{ var }}' evaluates to True"
      when: var
      vars:
        var: 'abc'

gives

fatal: [localhost]: FAILED! => 
  msg: |-
    The conditional check 'var' failed. The error was: error while 
    evaluating conditional (var): 'abc' is undefined

Explicit cast to Boolean prevents the error but evaluates to False i.e. will be always skipped (unless var='True'). When the filter bool is used the options ANSIBLE_CONDITIONAL_BARE_VARS=true and ANSIBLE_CONDITIONAL_BARE_VARS=false have no effect

    - debug:
        msg: "String '{{ var }}' evaluates to True"
      when: var|bool
      vars:
        var: 'abc'

gives

skipping: [localhost]

3. Quoting from Porting guide 2.8 Bare variables in conditionals

  - include_tasks: teardown.yml
    when: teardown

  - include_tasks: provision.yml
    when: not teardown

" based on a variable you define as a string (with quotation marks around it):"

• In Ansible 2.7 and earlier, the two conditions above evaluated as True and False respectively if teardown: 'true'

• In Ansible 2.7 and earlier, both conditions evaluated as False if teardown: 'false'

• In Ansible 2.8 and later, you have the option of disabling conditional bare variables, so when: teardown always evaluates as True and when: not teardown always evaluates as False when teardown is a non-empty string (including 'true' or 'false')

4. Quoting from CONDITIONAL_BARE_VARS

"Expect that this setting eventually will be deprecated after 2.12"

Heredoc sounds more convenient for this purpose. It is used to send multiple commands to a command interpreter program like ex or cat

cat << EndOfMessage
This is line 1.
This is line 2.
Line 3.
EndOfMessage

The string after << indicates where to stop.

To send these lines to a file, use:

cat > $FILE <<- EOM
Line 1.
Line 2.
EOM

You could also store these lines to a variable:

read -r -d '' VAR << EOM
This is line 1.
This is line 2.
Line 3.
EOM

This stores the lines to the variable named VAR.

When printing, remember the quotes around the variable otherwise you won't see the newline characters.

echo "$VAR"

Even better, you can use indentation to make it stand out more in your code. This time just add a - after << to stop the tabs from appearing.

read -r -d '' VAR <<- EOM
    This is line 1.
    This is line 2.
    Line 3.
EOM

But then you must use tabs, not spaces, for indentation in your code.

If you want to use a function form a package or module in python you have to import and reference them. For example normally you do the following to draw 5 points( [1,5],[2,4],[3,3],[4,2],[5,1]) in the space:

import matplotlib.pyplot
matplotlib.pyplot.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
matplotlib.pyplot.show()

In your solution

from matplotlib import*

This imports the package matplotlib and "plot is not defined" means there is no plot function in matplotlib you can access directly, but instead if you import as

from matplotlib.pyplot import *
plot([1,2,3,4,5],[5,4,3,2,1],"bx")
show()

Now you can use any function in matplotlib.pyplot without referencing them with matplotlib.pyplot.

I would recommend you to name imports you have, in this case you can prevent disambiguation and future problems with the same function names. The last and clean version of above example looks like:

import matplotlib.pyplot as plt
plt.plot([1,2,3,4,5],[5,4,3,2,1],"bx")
plt.show()

Simply put, you need to rewrite all of your database connections and queries.

You are using mysql_* functions which are now deprecated and will be removed from PHP in the future. So you need to start using MySQLi or PDO instead, just as the error notice warned you.

A basic example of using PDO (without error handling):

<?php
$db = new PDO('mysql:host=localhost;dbname=testdb;charset=utf8', 'username', 'password');
$result = $db->exec("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");
$insertId = $db->lastInsertId();
?>

A basic example of using MySQLi (without error handling):

$db = new mysqli($DBServer, $DBUser, $DBPass, $DBName);
$result = $db->query("INSERT INTO table(firstname, lastname) VAULES('John', 'Doe')");

Here's a handy little PDO tutorial to get you started. There are plenty of others, and ones about the PDO alternative, MySQLi.

Response.Write(@"<script language='javascript'>alert('Message: 
\n" + "Hi!" + " .');</script>");

This worked for me. But it gives only the main menu name. That is if user has opened Settings --> Bluetooth --> Device Name screen, RunningAppProcessInfo calls it as just Settings. Not able to drill down furthur

ActivityManager activityManager = (ActivityManager) context.getSystemService( Context.ACTIVITY_SERVICE );
                PackageManager pm = context.getPackageManager();
                List<RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
                for(RunningAppProcessInfo appProcess : appProcesses) {              
                    if(appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
                        CharSequence c = pm.getApplicationLabel(pm.getApplicationInfo(appProcess.processName, PackageManager.GET_META_DATA));
                        Log.i("Foreground App", "package: " + appProcess.processName + " App: " + c.toString());
                    }               
                }

Because '' is not a valid Javascript/JSON object. An empty object would be '{}'

For reference: https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse

I've made an Int type extension. tested it in playground, hope this is useful. It also accepts negative ranges:

extension Int
{
    static func random(range: Range<Int> ) -> Int
    {
        var offset = 0

        if range.startIndex < 0   // allow negative ranges
        {
            offset = abs(range.startIndex)
        }

        let mini = UInt32(range.startIndex + offset)
        let maxi = UInt32(range.endIndex   + offset)

        return Int(mini + arc4random_uniform(maxi - mini)) - offset
    }
}

use like

var aRandomInt = Int.random(-500...100)  // returns a random number within the given range.

or define it as a Range extension as property like this:

extension Range
{
    var randomInt: Int
    {
        get
        {
            var offset = 0

            if (startIndex as Int) < 0   // allow negative ranges
            {
                offset = abs(startIndex as Int)
            }

            let mini = UInt32(startIndex as Int + offset)
            let maxi = UInt32(endIndex   as Int + offset)

            return Int(mini + arc4random_uniform(maxi - mini)) - offset
        }
    }
}

// usage example: get an Int within the given Range:
let nr = (-1000 ... 1100).randomInt

Here's how to do it with list comprehension:

a = (1, 2, 3)
b = (4, 5, 6)
[print('f:', i, '; b', j) for i, j in zip(a, b)]

prints:

f: 1 ; b 4
f: 2 ; b 5
f: 3 ; b 6

Looking at the sample I guess you mean that a string array is actually an array of HEX representation of bytes, don't you?

If yes, then for each string item I would do the following:

1. check that a string consists only of 2 characters
2. these chars are in '0'..'9' or 'a'..'f' interval (take their case into account as well)
3. convert each character to a corresponding number, subtracting code value of '0' or 'a'

4. build a byte value, where first char is higher bits and second char is lower ones. E.g.

   int byteVal = (firstCharNumber << 4) | secondCharNumber;

--device works until your USB device gets unplugged/replugged and then it stops working. You have to use cgroup devices.allow get around it.
You could just use -v /dev:/dev but that's unsafe as it maps all the devices from your host into the container, including raw disk devices and so forth. Basically this allows the container to gain root on the host, which is usually not what you want.
Using the cgroups approach is better in that respect and works on devices that get added after the container as started.

See details here: Accessing USB Devices In Docker without using --privileged

It's a bit hard to paste, but in a nutshell, you need to get the major number for your character device and send that to cgroup:

189 is the major number of /dev/ttyUSB*, which you can get with 'ls -l'. It may be different on your system than on mine:

root@server:~# echo 'c 189:* rwm' > /sys/fs/cgroup/devices/docker/$A*/devices.allow  
(A contains the docker containerID)

Then start your container like this:

docker run -v /dev/bus:/dev/bus:ro -v /dev/serial:/dev/serial:ro -i -t --entrypoint /bin/bash debian:amd64

without doing this, any newly plugged or rebooting device after the container started, will get a new bus ID and will not be allowed access in the container.

There is another useful method called AutoResizeColumn which allows you to auto size a specific column with the required parameter.

You can call it like this:

listview1.AutoResizeColumn(1, ColumnHeaderAutoResizeStyle.ColumnContent);
listview1.AutoResizeColumn(2, ColumnHeaderAutoResizeStyle.ColumnContent);
listview1.AutoResizeColumn(3, ColumnHeaderAutoResizeStyle.HeaderSize);
listview1.AutoResizeColumn(4, ColumnHeaderAutoResizeStyle.HeaderSize);

For the kinds of large files I tend to get, I generally wouldn't even do this in R. I would use the cut command in Linux to process data before it gets to R. This isn't a critique of R, just a preference for using some very basic Linux tools like grep, tr, cut, sort, uniq, and occasionally sed & awk (or Perl) when there's something to be done about regular expressions.

Another reason to use standard GNU commands is that I can pass them back to the source of the data and ask that they prefilter the data so that I don't get extraneous data. Most of my colleagues are competent with Linux, fewer know R.

(Updated) A method that I would like to use before long is to pair mmap with a text file and examine the data in situ, rather than read it at all into RAM. I have done this with C, and it can be blisteringly fast.

if num in range(min, max):
  """do stuff..."""
else:
  """do other stuff..."""

I had same issue, with Latest Spring 4.1.1 onwards you need to add following jars to pom.xml.

If you hate numpy, get out RPy and your local copy of R, and use it instead.

(I would also echo to make you you really need to invert the matrix. In R, for example, linalg.solve and the solve() function don't actually do a full inversion, since it is unnecessary.)

You don't use ls to get a file's permission information. You use the stat command. It will give you the numerical values you want. The "Unix Way" says that you should invent your own script using ls (or 'echo *') and stat and whatever else you like to give the information in the format you desire.

import os
os.system('file_path/filename.mp3')

if( isset( $_POST['login'] ) &&  strlen( $_POST['login'] ))
{
  // valid $_POST['login'] is set and its value is greater than zero
}
else
{
  //error either $_POST['login'] is not set or $_POST['login'] is empty form field

DIVs inherently lack any useful meaning, other than to divide, of course.

Best course of action would be to add a meaningful class name to them, and style their individual margins in CSS.

<h1>Important Title</h1>
<div class="testimonials">...</div>
<div class="footer">...</div>

h1 {margin-bottom: 0.1em;}
div.testimonials {margin-bottom: 0.2em;}
div.footer {margin-bottom: 0;}

I know this has already been answered and its stupid late but I think this should be here. This is a regex that matches any kind of url.

process.cwd() returns the current working directory,

__dirname returns the directory name of the directory containing the JavaScript source code file

There is a calc function in both SCSS [compile-time] and CSS [run-time]. You're likely invoking the former instead of the latter.

For obvious reasons mixing units won't work compile-time, but will at run-time.

You can force the latter by using unquote, a SCSS function.

.selector { height: unquote("-webkit-calc(100% - 40px)"); }

git rev-parse --show-toplevel

could be enough if executed within a git repo.
From git rev-parse man page:

--show-toplevel

Show the absolute path of the top-level directory.

For older versions (before 1.7.x), the other options are listed in "Is there a way to get the git root directory in one command?":

git rev-parse --git-dir

That would give the path of the .git directory.

The OP mentions:

git rev-parse --show-prefix

which returns the local path under the git repo root. (empty if you are at the git repo root)

Note: for simply checking if one is in a git repo, I find the following command quite expressive:

git rev-parse --is-inside-work-tree

And yes, if you need to check if you are in a .git git-dir folder:

git rev-parse --is-inside-git-dir

This will only return 1 row, because you're just selecting a COUNT(). you will use mysql_num_rows() on the $query in this case.

If you want to get a count of each of the ID's, add GROUP BY id to the end of the string.

Performance-wise, don't ever ever ever use * in your queries. If there is 100 unique fields in a table and you want to get them all, you write out all 100, not *. This is because * has to recalculate how many fields it has to go, every single time it grabs a field, which takes a lot more time to call.

This is a warning for usual. You can either disable it by

#pragma warning(disable:4996)

or simply use fopen_s like Microsoft has intended.

But be sure to use the pragma before other headers.

I know it's not the answer to the original question, but you may find yourself here with this problem.

If you want all of the duplicate items in your results, the following works.

var duplicates = list
    .GroupBy( x => x )               // group matching items
    .Where( g => g.Skip(1).Any() )   // where the group contains more than one item
    .SelectMany( g => g );           // re-expand the groups with more than one item

In my situation I need all duplicates so that I can mark them in the UI as being errors.

This can happen if the @Service class is marked abstract.

If dir does not exist, create it:

data-target is used by bootstrap to make your life easier. You (mostly) do not need to write a single line of Javascript to use their pre-made JavaScript components.

<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  [...]
</div>

In this example, the button has data-target="#myModal", if you click on it, <div id="myModal">...</div> will be modified (in this case faded in). This happens because #myModal in CSS selectors points to elements that have an id attribute with the myModal value.

I think @ben-rollert's solution is a good solution.

You just have to be careful if you want to use this solution in a function inside a new package.

When developping packages, it's recommended to use the syntaxe packagename::function_name() (see http://kbroman.org/pkg_primer/pages/depends.html).

In this case, you have to use the version of as.Date() defined by the zoo library.

Here is an example :

> devtools::session_info()
Session info ----------------------------------------------------------------------------------------------------------------------------------------------------

 ui       RStudio (1.0.35)

Packages --------------------------------------------------------------------------------------------------------------------------------------------------------

 package  * version date       source        
 devtools   1.12.0  2016-06-24 CRAN (R 3.3.1)

 memoise    1.0.0   2016-01-29 CRAN (R 3.2.3)
 withr      1.0.2   2016-06-20 CRAN (R 3.2.3)

> as.Date(zoo::as.yearmon("1989-10", "%Y-%m")) 
Error in as.Date.default(zoo::as.yearmon("1989-10", "%Y-%m")) : 
  do not know how to convert 'zoo::as.yearmon("1989-10", "%Y-%m")' to class “Date”

> zoo::as.Date(zoo::as.yearmon("1989-10", "%Y-%m"))
[1] "1989-10-01"

So if you're developping a package, the good practice is to use :

zoo::as.Date(zoo::as.yearmon("1989-10", "%Y-%m"))

Using lodash and not pure javascript

This is actually quite simple using lodash and very easy to add/modify filters.

import _ from 'lodash';

async getUsersWithFilter(filters) {
     const users = yourArrayOfSomethingReally();

    // Some properties of the 'filters' object can be null or undefined, so create a new object without those undefined properties and filter by those who are defined
    const filtersWithoutUndefinedValuesObject = _.omitBy(
      filters,
      _.isNil,
    );

    return _.filter(users, { ...filtersWithoutUndefinedValuesObject });
}

1. The omitBy function checks your filters object and removes any value that is null or undefined (if you take it out, the lodash.filter function wont return any result.

2. The filter function will filter out all the objects who's values don't match with the object you pass as a second argument to the function (which in this case, is your filters object.)

Why use this?

Well, assume you have this object:

const myFiltersObj = {

   name: "Java",
   age: 50

};

If you want to add another filter, just add a new property to the myFilterObj, like this:

const myFiltersObj = {

   name: "Java",
   email: 50,
   country: "HND"

};

Call the getUsersWithFilter function, and it will work just fine. If you skip, let's say the name property in the object, the getUsersWithFilter function will filter by the email and country just fine.

Add this to your main CSS:

table td {
    border-top: none !important;
}

Use this for newer versions of bootstrap:

.table th, .table td { 
     border-top: none !important; 
 }

This macro adds a hyperlink to the worksheet with the same name, I also modify the range to be more flexible, just change the first cell in the code. Works like a charm

Sub hyper()
 Dim cl As Range
 Dim nS As String

 Set MyRange = Sheets("Sheet1").Range("B16")
 Set MyRange = Range(MyRange, MyRange.End(xlDown))

 For Each cl In MyRange
  nS = cl.Value
  cl.Hyperlinks.Add Anchor:=cl, Address:="", SubAddress:="'" & nS & "'" & "!B16", TextToDisplay:=nS
 Next
End Sub

I also wanted to read the Request.Body without automatically map it to some action parameter model. Tested a lot of different ways before solved this. And I didn´t find any working solution described here. This solution is currently based on the .NET Core 3.0 framework.

reader.readToEnd() seamed like a simple way, even though it compiled, it throwed an runtime exception required me to use async call. So instead I used ReadToEndAsync(), however it worked sometimes, and sometimes not. Giving me errors like, cannot read after stream is closed. The problem is that we cannot guarantee that it will return the result in the same thread (even if we use the await). So we need some kind of callback. This solution worked for me.

[Route("[controller]/[action]")]
public class MyController : ControllerBase
{

    // ...

    [HttpPost]
    public async void TheAction()
    {
        try
        {
            HttpContext.Request.EnableBuffering();
            Request.Body.Position = 0;
            using (StreamReader stream = new StreamReader(HttpContext.Request.Body))
            {
                var task = stream
                    .ReadToEndAsync()
                    .ContinueWith(t => {
                        var res = t.Result;
                        // TODO: Handle the post result!
                    });

                // await processing of the result
                task.Wait();
            }
        }
        catch (Exception ex)
        {
            _logger.LogError(ex, "Failed to handle post!");
        }
    }

I like Jaco Pretorius' solution, but I wanted to make the "this" keyword a bit more useful by pointing it to the module/namespace object. My version of skillet:

(function ($, undefined) {

    console.log(this);

}).call(window.myNamespace = window.myNamespace || {}, jQuery);

It should by located in: ~/Library/Developer/Xcode/DerivedData.

If you changed the defaults, you can see where the build directory is by going to File->Workspace Settings then look at Build Location

This worked for me:

select * from mytable
where array_to_string(pub_types, ',') like '%Journal%'

Depending on your normalization needs, it might be better to implement a separate table with a FK reference as you may get better performance and manageability.

The problem is you haven't declared your interface state replace any with your suitable variable type of the 'value'

Here is a good reference

interface AppProps {
   //code related to your props goes here
}

interface AppState {
   value: any
}

class App extends React.Component<AppProps, AppState> {
  // ...
}

It's syntatic sugar and a handy shorthand for brief if/else blocks that only contain one statement. Functionally, both constructs should perform identically.

Komodo is wonderful, and it runs on OS X; they have a free version, Komodo Edit.

UPDATE from 2015: I've switched to PHPStorm from Jetbrains, the same folks that built IntelliJ IDEA and Resharper. It's better. Not just better. It's well worth the money.

When you convert an address or object to a lat/long it is called Geocoding.

There are a lot geocoding solutions around. The solution right for your project will depend on the acceptability of the licensing terms of each geocoding solution. Both Microsoft Virtual Earth and Google Maps offer solutions which are free to use under a very restrictive licenses...

I am shamelessly copying the excerpts from man page of top

VIRT -- Virtual Image (kb) The total amount of virtual memory used by the task. It includes all code, data and shared libraries plus pages that have been swapped out and pages that have been mapped but not used.

SWAP -- Swapped size (kb) Memory that is not resident but is present in a task. This is memory that has been swapped out but could include additional non- resident memory. This column is calculated by subtracting physical memory from virtual memory

When you want to generate URL from your Business Logic layer, you do not have the flexibility of using ASP.NET Web Form's Page class/ Control's ResolveUrl(..) etc. Moreover, you may need to generate URL from ASP.NET MVC controller too where you not only miss the Web Form's ResolveUrl(..) method, but also you cannot get the Url.Action(..) even though Url.Action takes only Controller name and Action name, not the relative url.

I tried using

var uri = new Uri(absoluteUrl, relativeUrl)

approach, but there is a problem too. If the web application is hosted in IIS virtual directory, where the url of the app is like this : http://localhost/MyWebApplication1/, and the relative url is "/myPage" then the relative url is resolved as "http://localhost/MyPage" which is another problem.

Therefore, in order to overcome such problems, I have written a UrlUtils class which can work from a class library. So, it wont depend on Page class but it depends on ASP.NET MVC. So, if you dont mind adding reference to MVC dll to your class library project then my class will work smoothly. I have tested in IIS virtual directory scenario where the web application url is like this : http://localhost/MyWebApplication/MyPage. I realized that, sometimes we need to make sure that the Absolute url is SSL url or non SSL url. So, I wrote my class library supporting this option. I have restricted this class library so that the relative url can be absolute url or a relative url that starts with '~/'.

Using this library, I can call

string absoluteUrl = UrlUtils.MapUrl("~/Contact");

Returns : http://localhost/Contact when the page url is : http://localhost/Home/About

Returns : http://localhost/MyWebApplication/Contact when the page url is : http://localhost/MyWebApplication/Home/About

  string absoluteUrl = UrlUtils.MapUrl("~/Contact", UrlUtils.UrlMapOptions.AlwaysSSL);

Returns : **https**://localhost/MyWebApplication/Contact when the page url is : http://localhost/MyWebApplication/Home/About

Here is my class Library :

 public class UrlUtils
    {
        public enum UrlMapOptions
        {
            AlwaysNonSSL,
            AlwaysSSL,
            BasedOnCurrentScheme
        }

        public static string MapUrl(string relativeUrl, UrlMapOptions option = UrlMapOptions.BasedOnCurrentScheme)
        {
            if (relativeUrl.StartsWith("http://", StringComparison.OrdinalIgnoreCase) ||
                relativeUrl.StartsWith("https://", StringComparison.OrdinalIgnoreCase))
                return relativeUrl;

            if (!relativeUrl.StartsWith("~/"))
                throw new Exception("The relative url must start with ~/");

            UrlHelper theHelper = new UrlHelper(HttpContext.Current.Request.RequestContext);

            string theAbsoluteUrl = HttpContext.Current.Request.Url.GetLeftPart(UriPartial.Authority) +
                                           theHelper.Content(relativeUrl);

            switch (option)
            {
                case UrlMapOptions.AlwaysNonSSL:
                    {
                        return theAbsoluteUrl.StartsWith("https://", StringComparison.OrdinalIgnoreCase)
                            ? string.Format("http://{0}", theAbsoluteUrl.Remove(0, 8))
                            : theAbsoluteUrl;
                    }
                case UrlMapOptions.AlwaysSSL:
                    {
                        return theAbsoluteUrl.StartsWith("https://", StringComparison.OrdinalIgnoreCase)
                            ? theAbsoluteUrl
                            : string.Format("https://{0}", theAbsoluteUrl.Remove(0, 7));
                    }
            }

            return theAbsoluteUrl;
        }
    }   

I didnt know about css3pie.com, a very useful site after seeing this post:

But what after testing it out it didnt work for me either. However I found that wrapping it in the .PHP file worked fine. So instead of:

behavior: url(PIE.htc);

use this:

behavior: url(PIE.php);

I put mine in a folder called jquery, so mine was:

 behavior: url(jquery/PIE.php);

So goto their downloads or get it here:

http://css3pie.com/download-latest

And use their PHP file. Inside the PHP file it explains that some servers are not configured for proper .HTC usage. And that was the problem I had.

Try it! I did, it works. Hope this helps others out too.
