Basically what others have already posted but IMHO a bit cleaner:

$('<iframe/>', {
    src: 'https://example.com/',
    load: function() {
        alert("loaded")
    }
}).appendTo('body');

This line will allow you to see all rows (up to the number that you set as 'max_rows') without any rows being hidden by the dots ('.....') that normally appear between head and tail in the print output.

pd.options.display.max_rows = 500

On most platforms, long and int are the same size (32 bits). Still, it does have its own format specifier:

long n;
unsigned long un;
printf("%ld", n); // signed
printf("%lu", un); // unsigned

For 64 bits, you'd want a long long:

long long n;
unsigned long long un;
printf("%lld", n); // signed
printf("%llu", un); // unsigned

Oh, and of course, it's different in Windows:

printf("%l64d", n); // signed
printf("%l64u", un); // unsigned

Frequently, when I'm printing 64-bit values, I find it helpful to print them in hex (usually with numbers that big, they are pointers or bit fields).

unsigned long long n;
printf("0x%016llX", n); // "0x" followed by "0-padded", "16 char wide", "long long", "HEX with 0-9A-F"

will print:

0x00000000DEADBEEF

Btw, "long" doesn't mean that much anymore (on mainstream x64). "int" is the platform default int size, typically 32 bits. "long" is usually the same size. However, they have different portability semantics on older platforms (and modern embedded platforms!). "long long" is a 64-bit number and usually what people meant to use unless they really really knew what they were doing editing a piece of x-platform portable code. Even then, they probably would have used a macro instead to capture the semantic meaning of the type (eg uint64_t).

char c;       // 8 bits
short s;      // 16 bits
int i;        // 32 bits (on modern platforms)
long l;       // 32 bits
long long ll; // 64 bits 

Back in the day, "int" was 16 bits. You'd think it would now be 64 bits, but no, that would have caused insane portability issues. Of course, even this is a simplification of the arcane and history-rich truth. See wiki:Integer

One possible approach for Helper method testing in the Ruby on Rails console is:

Struct.new(:t).extend(YourHelper).your_method(*arg)

And for reload do:

reload!; Struct.new(:t).extend(YourHelper).your_method(*arg)

I think that the best way to do this is:

Stash your local changes:

git stash

Update the branch to the latest code

git pull

Merge your local changes into the latest code:

git stash apply

Add, commit and push your changes

git add
git commit
git push

In my experience this is the path to least resistance with Git (on the command line anyway).

You should bind the tap event, the click does not exist on mobile safari or in the UIWbview. You can also use this polyfill ,to avoid the 300ms delay when a link is touched.

(Please note that the above accepted Answer provided for file/project structure is absolutely correct.)

Also..

In addition to properly setting up the project file structure, we have to tell flask to look in the appropriate level of the directory hierarchy.

for example..

    app = Flask(__name__, template_folder='../templates')

    app = Flask(__name__, template_folder='../templates', static_folder='../static')

Starting with ../ moves one directory backwards and starts there.

Starting with ../../ moves two directories backwards and starts there (and so on...).

Hope this helps

To set the PATH variable, within the Makefile only, use something like:

PATH := $(PATH):/my/dir

test:
@echo my new PATH = $(PATH)

guppy3 is quite simple to use. At some point in your code, you have to write the following:

from guppy import hpy
h = hpy()
print(h.heap())

This gives you some output like this:

Partition of a set of 132527 objects. Total size = 8301532 bytes.
Index  Count   %     Size   % Cumulative  % Kind (class / dict of class)
0  35144  27  2140412  26   2140412  26 str
1  38397  29  1309020  16   3449432  42 tuple
2    530   0   739856   9   4189288  50 dict (no owner)

You can also find out from where objects are referenced and get statistics about that, but somehow the docs on that are a bit sparse.

There is a graphical browser as well, written in Tk.

For Python 2.x, use Heapy.

What worked for me on an Amazon EC2 server was:

If you dont care about the aspect ration (i.e you want to force the image to a particular dimension), here is a simplified answer

// for jpg 
function resize_imagejpg($file, $w, $h) {
   list($width, $height) = getimagesize($file);
   $src = imagecreatefromjpeg($file);
   $dst = imagecreatetruecolor($w, $h);
   imagecopyresampled($dst, $src, 0, 0, 0, 0, $w, $h, $width, $height);
   return $dst;
}

 // for png
function resize_imagepng($file, $w, $h) {
   list($width, $height) = getimagesize($file);
   $src = imagecreatefrompng($file);
   $dst = imagecreatetruecolor($w, $h);
   imagecopyresampled($dst, $src, 0, 0, 0, 0, $w, $h, $width, $height);
   return $dst;
}

// for gif
function resize_imagegif($file, $w, $h) {
   list($width, $height) = getimagesize($file);
   $src = imagecreatefromgif($file);
   $dst = imagecreatetruecolor($w, $h);
   imagecopyresampled($dst, $src, 0, 0, 0, 0, $w, $h, $width, $height);
   return $dst;
}

Now let's handle the upload part. First step, upload the file to your desired directory. Then called one of the above functions based on file type (jpg, png or gif) and pass the absolute path of your uploaded file as below:

 // jpg  change the dimension 750, 450 to your desired values
 $img = resize_imagejpg('path/image.jpg', 750, 450);

The return value $img is a resource object. We can save to a new location or override the original as below:

 // again for jpg
 imagejpeg($img, 'path/newimage.jpg');

Hope this helps someone. Check these links for more on resizing Imagick::resizeImage and imagejpeg()

Update: in Rails 3.0.9: env method defined in railties/lib/rails.rb

In a different thread Justin suggests that the fastest way is to use strtok()

 $url = strtok($url, '?');

See his full answer with speed tests as well here: https://stackoverflow.com/a/1251650/452515

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

Add the active: false option (documentation)..

$("#accordion").accordion({ header: "h3", collapsible: true, active: false });

sudo dpkg-reconfigure dash 

Then select no.

Isn't it that simple ... tested working ..

eg.

---
- hosts: localhost
  vars:
     cleandir: /var/lib/cloud/
  tasks:
   - shell: ls -a -I '.' -I '..' {{ cleandir }}
     register: ls2del
     ignore_errors: yes
   - name: Cleanup {{ cleandir }}
     file:
       path: "{{ cleandir }}{{ item }}"
       state: absent
     with_items: "{{ ls2del.stdout_lines }}"

Found another example where you would have to call destructor(s) manually. Suppose you have implemented a variant-like class that holds one of several types of data:

struct Variant {
    union {
        std::string str;
        int num;
        bool b;
    };
    enum Type { Str, Int, Bool } type;
};

If the Variant instance was holding a std::string, and now you're assigning a different type to the union, you must destruct the std::string first. The compiler will not do that automatically.

I've found the updated answer from this video, the accepted answer didn't work for me.

First clone the latest repo from git (if haven't) using git clone <HTTPs link of the project> (or using SSH) then go to the desire branch using git checkout <branch name> .

Use the command

git log

to check the latest commits. Copy the shal of the particular commit. Then use the command

git fetch origin <Copy paste the shal here>

After pressing enter key. Now use the command

git checkout FETCH_HEAD

Now the particular commit will be available to your local. Change anything and push the code using git push origin <branch name> . That's all. Check the video for reference.

the window.onload event will fire when everything is loaded, including images etc.

You would want to check the DOM ready status if you wanted your js code to execute as early as possible, but you still need to access DOM elements.

That plugin will automatically do the "organize import" action on file save: https://github.com/dubreuia/intellij-plugin-save-actions.

To install: "File > Settings > Plugins > Browse repositories... > Search 'Save Actions' > Category 'Code tools'". Then activate the "organize import" save action.

If you really want to remove all of the repository, leaving only the working directory then it should be as simple as this.

rm -rf .git

The usual provisos about rm -rf apply. Make sure you have an up to date backup and are absolutely sure that you're in the right place before running the command. etc., etc.

From crtdbg.h (and many other headers):

#ifndef NULL
#ifdef __cplusplus
#define NULL    0
#else
#define NULL    ((void *)0)
#endif
#endif

Therefore NULL is 0, at least on the Windows platform. So no, not that I know of.

Add this style to your style.xml file

 <style name="AppTheme.NoActionBar">
     <item name="windowActionBar">false</item>
     <item name="windowNoTitle">true</item>
 </style>

After that reference this style name into your androidManifest.xml in perticular activity in which you don't want to see titlebar, as like below.

<activity android:name=".youractivityname"
     android:theme="@style/AppTheme.NoActionBar">
</activity>

Please Make sure that settings.XML file in the folder .m2 is valid first Then after clean the repository using below command in cmd

cd %userprofile%\.m2\repository
for /r %i in (*.lastUpdated) do del %i

Do this:

$(document).ready(function(){
    $(".header").click(function(){
        $(this).children(".children").toggle();
    });
   $(".header a").click(function(e) {
        e.stopPropagation();
   });
});

If you have the month number, you can first create a date from it with a default date of 1st and default year of the current year, then extract the month name from the date created:

echo date("F", strtotime(date("Y") ."-". $i ."-01"))

This code assumes you have your month number stored in $i

Table relationships vs. entity relationships

In a relational database system, there can be only three types of table relationships:

• one-to-many (via a Foreign Key column)
• one-to-one (via a shared Primary Key)
• many-to-many (via a link table with two Foreign Keys referencing two separate parent tables)

So, a one-to-many table relationship looks as follows:

Note that the relationship is based on the Foreign Key column (e.g., post_id) in the child table.

So, there is a single source of truth when it comes to managing a one-to-many table relationship.

Now, if you take a bidirectional entity relationship that maps on the one-to-many table relationship we saw previously:

If you take a look at the diagram above, you can see that there are two ways to manage this relationship.

In the Post entity, you have the comments collection:

@OneToMany(
    mappedBy = "post",
    cascade = CascadeType.ALL,
    orphanRemoval = true
)
private List<PostComment> comments = new ArrayList<>();

And, in the PostComment, the post association is mapped as follows:

@ManyToOne(
    fetch = FetchType.LAZY
)
@JoinColumn(name = "post_id")
private Post post;

So, you have two sides that can change the entity association:

• By adding an entry in the comments child collection, a new post_comment row should be associated with the parent post entity via its post_id column.
• By setting the post property of the PostComment entity, the post_id column should be updated as well.

Because there are two ways to represent the Foreign Key column, you must define which is the source of truth when it comes to translating the association state change into its equivalent Foreign Key column value modification.

MappedBy (a.k.a the inverse side)

The mappedBy attribute tells that the @ManyToOne side is in charge of managing the Foreign Key column, and the collection is used only to fetch the child entities and to cascade parent entity state changes to children (e.g., removing the parent should also remove the child entities).

It's called the inverse side because it references the child entity property that manages this table relationship.

Synchronize both sides of a bidirectional association

Now, even if you defined the mappedBy attribute and the child-side @ManyToOne association manages the Foreign Key column, you still need to synchronize both sides of the bidirectional association.

The best way to do that is to add these two utility methods:

public void addComment(PostComment comment) {
    comments.add(comment);
    comment.setPost(this);
}

public void removeComment(PostComment comment) {
    comments.remove(comment);
    comment.setPost(null);
}

The addComment and removeComment methods ensure that both sides are synchronized. So, if we add a child entity, the child entity needs to point to the parent and the parent entity should have the child contained in the child collection.

Simple solution for standard observablecollection that I've used:

DO NOT ADD to your property OR CHANGE it's inner items DIRECTLY, instead, create some temp collection like this

ObservableCollection<EntityViewModel> tmpList= new ObservableCollection<EntityViewModel>();

and add items or make changes to tmpList,

tmpList.Add(new EntityViewModel(){IsRowChecked=false}); //Example
tmpList[0].IsRowChecked= true; //Example
...

then pass it to your actual property by assignment.

ContentList=tmpList;

this will change whole property which causes notice the INotifyPropertyChanged as you need.

If the package is on PYPI, download it and its dependencies to some local directory. E.g.

$ mkdir /pypi && cd /pypi
$ ls -la
  -rw-r--r--   1 pavel  staff   237954 Apr 19 11:31 Flask-WTF-0.6.tar.gz
  -rw-r--r--   1 pavel  staff   389741 Feb 22 17:10 Jinja2-2.6.tar.gz

  -rw-r--r--   1 pavel  staff  2597214 Apr 10 18:26 SQLAlchemy-0.7.6.tar.gz
  -rw-r--r--   1 pavel  staff  1108056 Feb 22 17:10 Werkzeug-0.8.2.tar.gz

  -rw-r--r--   1 pavel  staff   490192 Apr 16 12:00 flask-0.9-dev-2a6c80a.tar.gz

Some packages may have to be archived into similar looking tarballs by hand. I do it a lot when I want a more recent (less stable) version of something. Some packages aren't on PYPI, so same applies to them.

Suppose you have a properly formed Python application in ~/src/myapp. ~/src/myapp/setup.py will have install_requires list that mentions one or more things that you have in your /pypi directory. Like so:

  install_requires=[
    'boto',
    'Flask',
    'Werkzeug',
    # and so on

If you want to be able to run your app with all the necessary dependencies while still hacking on it, you'll do something like this:

$ cd ~/src/myapp
$ python setup.py develop --always-unzip --allow-hosts=None --find-links=/pypi

This way your app will be executed straight from your source directory. You can hack on things, and then rerun the app without rebuilding anything.

If you want to install your app and its dependencies into the current python environment, you'll do something like this:

$ cd ~/src/myapp
$ easy_install --always-unzip --allow-hosts=None --find-links=/pypi .

In both cases, the build will fail if one or more dependencies aren't present in /pypi directory. It won't attempt to promiscuously install missing things from Internet.

I highly recommend to invoke setup.py develop ... and easy_install ... within an active virtual environment to avoid contaminating your global Python environment. It is (virtualenv that is) pretty much the way to go. Never install anything into global Python environment.

If the machine that you've built your app has same architecture as the machine on which you want to deploy it, you can simply tarball the entire virtual environment directory into which you easy_install-ed everything. Just before tarballing though, you must make the virtual environment directory relocatable (see --relocatable option). NOTE: the destination machine needs to have the same version of Python installed, and also any C-based dependencies your app may have must be preinstalled there too (e.g. say if you depend on PIL, then libpng, libjpeg, etc must be preinstalled).

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

I know this is late info, but in jQuery, using .checked is possible and easy! If your element is something like:

<td>
    <input type="radio" name="bob" />
</td>

You can easily get/set checked state as such:

$("td").each(function()
{
    $(this).click(function()
    {
        var thisInput  = $(this).find("input[type=radio]");
        var checked = thisInput.is(":checked");
        thisInput[0].checked = (checked) ?  false : true;
    }
});

The secret is using the "[0]" array index identifier which is the ELEMENT of your jquery object! ENJOY!

Difference between last but one commit and last commit (plus current state, if any):

git diff HEAD~

or even (easier to type)

git diff @~

where @ is the synonim for HEAD of current branch and ~ means "give me the parent of mentioned revision".

A "ContractFilter mismatch at the EndpointDispatcher" means the receiver could not process the message because it did not match any of the contracts the receiver has configured for the endpoint which received the message.

This can be because:

• You have different contracts between client and sender.
• You're using a different binding between client and sender.
• The message security settings are not consistent between client and sender.

Have at look at the EndpointDispatcher class for more information on the subject.

So:

Make certain that your client and server contracts match.

• If you've generated your client from a WSDL, is the WSDL up-to-date?
• If you've made a recent change to the contract, have you deployed the right version of both client and server?
• If you've hand-crafted your client contract classes, make sure the namespaces, elements names and action names match the ones expected by the server.

Check the bindings are the same between client and server.

• If you're using a .config file to manage your endpoints, make sure the binding elements match.

Check the security settings are the same between client and server.

• If you're using a .config file to manage your endpoints, make sure the security elements match.

I know this is a really old post. But I want to share my module for configuring environment variables, I think it is very flexible solution. Here is the module json-configurator

var configJson = {
  'baseUrl': 'http://test.com',
  '$prod_baseUrl': 'https://prod.com',
  'endpoints': {
    'users': '<%= baseUrl %>/users',
    'accounts': '<%= baseUrl %>/accounts'
    },
  foo: 'bar',
  foobar: 'foobar',
  $prod_foo: 'foo in prod',
  $test_foo: 'foo in test',
  deep:{
    veryDeep: {
      publicKey: 'abc',
      secret: 'secret',
      $prod_secret: 'super secret'
    }
  }
};

var config = require('json-configurator')(configJson, 'prod');

console.log(config.deep.veryDeep.secret) 
// super secret 

console.log(config.endpoints.users)
// https://prod.com/users 

Then you can use process.env.NODE_ENV to get all the variables for your environment.

I'm not exactly sure what's causing this. You can try looking in your socket.py (mine is a different version, so line numbers from the trace don't match, and I'm afraid some other details might not match as well).

Anyway, it seems like a good practice to put your url fetching code in a try: ... except: ... block, and handle this with a short pause and a retry. The URL you're trying to fetch may be down, or too loaded, and that's stuff you'll only be able to handle in with a retry anyway.

If you go thru this IBM link on java, it says that on 32 bit windows the recommended heap size is 1.5 GB and the Maximum heap size is 1.8 GB. So your jvm does not gets initialized for -Xmx2G and above.

Also if you go thru this SO answer, clearly the DLL bindings are an issue for memory reservation changing which is no trivial task. Hence what may be recommended is that you go for 64-bit Windows and a 64-bit JVM. while it will chew up more RAM, you will have much more contiguous virtual address space.

The problem here is very simple. If you want to display value in JSP, you have to use <%= %> tag instead of <% %>, here is the solved code:

<tr> <td><%=rs.getInt("ID") %></td> <td><%=rs.getString("NAME") %></td> <td><%=rs.getString("SKILL") %></td> </tr>

Building on the solution by MoonScript, you could try this instead:

https://github.com/intuit/xhr-xdr-adapter/blob/master/src/xhr-xdr-adapter.js

The benefit is that since it's a lower level solution, it will enable CORS (to the extent possible) on IE 8/9 with other frameworks, not just with jQuery. I've had success using it with AngularJS, as well as jQuery 1.x and 2.x.

I discovered git-annex recently which I find awesome. It was designed for managing large files efficiently. I use it for my photo/music (etc.) collections. The development of git-annex is very active. The content of the files can be removed from the Git repository, only the tree hierarchy is tracked by Git (through symlinks). However, to get the content of the file, a second step is necessary after pulling/pushing, e.g.:

$ git annex add mybigfile
$ git commit -m'add mybigfile'
$ git push myremote
$ git annex copy --to myremote mybigfile ## This command copies the actual content to myremote
$ git annex drop mybigfile ## Remove content from local repo
...
$ git annex get mybigfile ## Retrieve the content
## or to specify the remote from which to get:
$ git annex copy --from myremote mybigfile

There are many commands available, and there is a great documentation on the website. A package is available on Debian.

Target parameters:

float width = 1024;
float height = 768;
var brush = new SolidBrush(Color.Black);

Your original file:

var image = new Bitmap(file);

Target sizing (scale factor):

float scale = Math.Min(width / image.Width, height / image.Height);

The resize including brushing canvas first:

var bmp = new Bitmap((int)width, (int)height);
var graph = Graphics.FromImage(bmp);

// uncomment for higher quality output
//graph.InterpolationMode = InterpolationMode.High;
//graph.CompositingQuality = CompositingQuality.HighQuality;
//graph.SmoothingMode = SmoothingMode.AntiAlias;

var scaleWidth = (int)(image.Width * scale);
var scaleHeight = (int)(image.Height * scale);

graph.FillRectangle(brush, new RectangleF(0, 0, width, height));
graph.DrawImage(image, ((int)width - scaleWidth)/2, ((int)height - scaleHeight)/2, scaleWidth, scaleHeight);

And don't forget to do a bmp.Save(filename) to save the resulting file.

If you use an = statement to assign a value to a var with an object on the right side, javascript will not copy but reference the object.

You can use lodash's clone method

var obj = {a: 25, b: 50, c: 75};
var A = _.clone(obj);

Or lodash's cloneDeep method if your object has multiple object levels

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.cloneDeep(obj);

Or lodash's merge method if you mean to extend the source object

var obj = {a: 25, b: {a: 1, b: 2}, c: 75};
var A = _.merge({}, obj, {newkey: "newvalue"});

Or you can use jQuerys extend method:

var obj = {a: 25, b: 50, c: 75};
var A = $.extend(true,{},obj);

Here is jQuery 1.11 extend method's source code :

jQuery.extend = jQuery.fn.extend = function() {
    var src, copyIsArray, copy, name, options, clone,
        target = arguments[0] || {},
        i = 1,
        length = arguments.length,
        deep = false;

    // Handle a deep copy situation
    if ( typeof target === "boolean" ) {
        deep = target;

        // skip the boolean and the target
        target = arguments[ i ] || {};
        i++;
    }

    // Handle case when target is a string or something (possible in deep copy)
    if ( typeof target !== "object" && !jQuery.isFunction(target) ) {
        target = {};

                if ( deep && copy && ( jQuery.isPlainObject(copy) || (copyIsArray = jQuery.isArray(copy)) ) ) {

                        clone = src && jQuery.isArray(src) ? src : [];

                    } else {
                        clone = src && jQuery.isPlainObject(src) ? src : {};
                    }

                    // Never move original objects, clone them
                    target[ name ] = jQuery.extend( deep, clone, copy );

                // Don't bring in undefined values
                } else if ( copy !== undefined ) {
                    target[ name ] = copy;
                }
            }
        }
    }

    // Return the modified object
    return target;
};

I just tried a bare-bones implementation and it just works:

public class Test {

    public static void main(String[] args) {
            JFrame frame = new JFrame("Hello");
            frame.setPreferredSize(new Dimension(200, 200));
            frame.add(new Board());
            frame.pack();
            frame.setVisible(true);
    }
}

public class Board extends JPanel {

    private Player player = new Player();

    public Board(){
        setBackground(Color.BLACK);
    }

    public void paintComponent(Graphics g){  
        super.paintComponent(g);
        g.setColor(Color.red);
        g.fillOval(player.getCenter().x, player.getCenter().y,
             player.getRadius(), player.getRadius());
    } 
}

public class Player {

    private Point center = new Point(50, 50);

    public Point getCenter() {
        return center;
    }

    private int radius = 10;

    public int getRadius() {
        return radius;
    }
}

your data grid needs to be bound to a sortable list in the first place.

Create this event handler:

    void MakeColumnsSortable_DataBindingComplete(object sender, DataGridViewBindingCompleteEventArgs e)
    {
        //Add this as an event on DataBindingComplete
        DataGridView dataGridView = sender as DataGridView;
        if (dataGridView == null)
        {
            var ex = new InvalidOperationException("This event is for a DataGridView type senders only.");
            ex.Data.Add("Sender type", sender.GetType().Name);
            throw ex;
        }

        foreach (DataGridViewColumn column in dataGridView.Columns)
            column.SortMode = DataGridViewColumnSortMode.Automatic;
    }

And initialize the event of each of your datragrids like this:

        dataGridView1.DataBindingComplete += MakeColumnsSortable_DataBindingComplete;

If all the previous answers didn't give any solution, you should check your user privileges.

If you could login as root to mysql then you should add this:

CREATE USER 'root'@'192.168.1.100' IDENTIFIED BY  '***';
GRANT ALL PRIVILEGES ON * . * TO  'root'@'192.168.1.100' IDENTIFIED BY  '***' WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0 ;

Then try to connect again using mysql -ubeer -pbeer -h192.168.1.100. It should work.

For phpMyAdmin I figured this out:

SELECT GROUP_CONCAT("ALTER TABLE ", TABLE_SCHEMA, '.', TABLE_NAME," CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;" SEPARATOR ' ') AS    OneSQLString
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA="yourtableschemaname"
AND TABLE_TYPE="BASE TABLE"

Just change yourtableschemaname and you're fine.

I recommend Derek Bruening's bar graph generator Perl script. Available at http://www.burningcutlery.com/derek/bargraph/

Here's your method:

public static Calendar toCalendar(Date date){ 
  Calendar cal = Calendar.getInstance();
  cal.setTime(date);
  return cal;
}

Everything else you are doing is both wrong and unnecessary.

BTW, Java Naming conventions suggest that method names start with a lower case letter, so it should be: dateToCalendar or toCalendar (as shown).

OK, let's milk your code, shall we?

DateFormat formatter = new SimpleDateFormat("yyyyMMdd");
date = (Date)formatter.parse(date.toString()); 

DateFormat is used to convert Strings to Dates (parse()) or Dates to Strings (format()). You are using it to parse the String representation of a Date back to a Date. This can't be right, can it?

if you want same string output then try below else use without double quotes for proper output

$str = '20130814';
  echo date('"F Y"', strtotime($str));

//output  : "August 2013" 

Use CTRL+D at each line and it will find the matching words and select them then you can use multiple cursors.

You can also use find to find all the occurrences and then it would be multiple cursors too.

Start menu → Accessories → right click on "Command prompt". In the menu, click "Run as Administrator" (on Windows XP you can just run it as usual), run netstat -anb, and then look through output for your program.

BTW, Skype by default tries to use ports 80 and 443 for incoming connections.

You can also run netstat -anb >%USERPROFILE%\ports.txt followed by start %USERPROFILE%\ports.txt to open the port and process list in a text editor, where you can search for the information you want.

You can also use PowerShell to parse netstat output and present it in a better way (or process it any way you want):

$proc = @{};
Get-Process | ForEach-Object { $proc.Add($_.Id, $_) };
netstat -aon | Select-String "\s*([^\s]+)\s+([^\s]+):([^\s]+)\s+([^\s]+):([^\s]+)\s+([^\s]+)?\s+([^\s]+)" | ForEach-Object {
    $g = $_.Matches[0].Groups;
    New-Object PSObject |
        Add-Member @{ Protocol =           $g[1].Value  } -PassThru |
        Add-Member @{ LocalAddress =       $g[2].Value  } -PassThru |
        Add-Member @{ LocalPort =     [int]$g[3].Value  } -PassThru |
        Add-Member @{ RemoteAddress =      $g[4].Value  } -PassThru |
        Add-Member @{ RemotePort =         $g[5].Value  } -PassThru |
        Add-Member @{ State =              $g[6].Value  } -PassThru |
        Add-Member @{ PID =           [int]$g[7].Value  } -PassThru |
        Add-Member @{ Process = $proc[[int]$g[7].Value] } -PassThru;
#} | Format-Table Protocol,LocalAddress,LocalPort,RemoteAddress,RemotePort,State -GroupBy @{Name='Process';Expression={$p=$_.Process;@{$True=$p.ProcessName; $False=$p.MainModule.FileName}[$p.MainModule -eq $Null] + ' PID: ' + $p.Id}} -AutoSize
} | Sort-Object PID | Out-GridView

Also it does not require elevation to run.

From the Android Studio download page:

Caution: Android Studio is currently available as an early access preview. Several features are either incomplete or not yet implemented and you may encounter bugs. If you are not comfortable using an unfinished product, you may want to instead download (or continue to use) the ADT Bundle (Eclipse with the ADT Plugin).

DMitryG's code "get the return value of the underlying MessageBox" has a bug so the timerResult is never actually correctly returned (MessageBox.Show call returns AFTER OnTimerElapsed completes). My fix is below:

public class TimedMessageBox {
    System.Threading.Timer _timeoutTimer;
    string _caption;
    DialogResult _result;
    DialogResult _timerResult;
    bool timedOut = false;

    TimedMessageBox(string text, string caption, int timeout, MessageBoxButtons buttons = MessageBoxButtons.OK, DialogResult timerResult = DialogResult.None)
    {
        _caption = caption;
        _timeoutTimer = new System.Threading.Timer(OnTimerElapsed,
            null, timeout, System.Threading.Timeout.Infinite);
        _timerResult = timerResult;
        using(_timeoutTimer)
            _result = MessageBox.Show(text, caption, buttons);
        if (timedOut) _result = _timerResult;
    }

    public static DialogResult Show(string text, string caption, int timeout, MessageBoxButtons buttons = MessageBoxButtons.OK, DialogResult timerResult = DialogResult.None) {
        return new TimedMessageBox(text, caption, timeout, buttons, timerResult)._result;
    }

    void OnTimerElapsed(object state) {
        IntPtr mbWnd = FindWindow("#32770", _caption); // lpClassName is #32770 for MessageBox
        if(mbWnd != IntPtr.Zero)
            SendMessage(mbWnd, WM_CLOSE, IntPtr.Zero, IntPtr.Zero);
        _timeoutTimer.Dispose();
        timedOut = true;
    }

    const int WM_CLOSE = 0x0010;
    [System.Runtime.InteropServices.DllImport("user32.dll", SetLastError = true, CharSet = System.Runtime.InteropServices.CharSet.Auto)]
    static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
    [System.Runtime.InteropServices.DllImport("user32.dll", CharSet = System.Runtime.InteropServices.CharSet.Auto)]
    static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
}

Probably u might be using a incorrect SDK version. Right click on your project. Select Properties-->Android. Note that 2.2 is the latest SDK. Check it and see if it gets compiled...

Edit

Also Do a clean after that

The increasingly popular D3 library handles the oddities of appending/manipulating svg very nicely. You may want to consider using it as opposed to the jQuery hacks mentioned here.

HTML

<svg xmlns="http://www.w3.org/2000/svg"></svg>

Javascript

var circle = d3.select("svg").append("circle")
    .attr("r", "10")
    .attr("style", "fill:white;stroke:black;stroke-width:5");

I prefer to use WebClient, it seems to handle SSL transparently:

http://msdn.microsoft.com/en-us/library/system.net.webclient.aspx

Some troubleshooting help here:

https://clipperhouse.com/webclient-fiddler-and-ssl/

$("#my-select option:contains(" + myText +")").attr("selected", true);

This returns the first option containing your text description.

 $(this).find('option:selected').text();

$('div.alldivs :first-child');

Or you can just refer to the id directly:

$('#div1');

As suggested, you might be better of using the child selector:

$('div.alldivs > div:first-child')

If you dont have to use first-child, you could use :first as also suggested, or $('div.alldivs').children(0).

In Tomcat 7, you can use "aliases" property. From the docs:

This attribute provides a list of external locations from which to load resources for this context. The list of aliases should be of the form "/aliasPath1=docBase1,/aliasPath2=docBase2" where aliasPathN must include a leading '/' and docBaseN must be an absolute path to either a .war file or a directory. A resource will be searched for in the first docBaseN for which aliasPathN is a leading path segment of the resource. If there is no such alias, then the resource will be searched in the usual way. These external locations will not be emptied if the context is un-deployed.

With ES6: This is now part of the language:

function myFunc(a, b = 0) {
   // function body
}

Please keep in mind that ES6 checks the values against undefined and not against truthy-ness (so only real undefined values get the default value - falsy values like null will not default).

With ES5:

function myFunc(a,b) {
  b = b || 0;

  // b will be set either to b or to 0.
}

This works as long as all values you explicitly pass in are truthy. Values that are not truthy as per MiniGod's comment: null, undefined, 0, false, ''

It's pretty common to see JavaScript libraries to do a bunch of checks on optional inputs before the function actually starts.

Mono comes with a wrapper, use theirs!

https://github.com/mono/mono/tree/master/mcs/class/Mono.Data.Sqlite/Mono.Data.Sqlite_2.0 gives code to wrap the actual SQLite dll ( http://www.sqlite.org/sqlite-shell-win32-x86-3071300.zip found on the download page http://www.sqlite.org/download.html/ ) in a .net friendly way. It works on Linux or Windows.

This seems the thinnest of all worlds, minimizing your dependence on third party libraries. If I had to do this project from scratch, this is the way I would do it.

Compare date only instead of date + time (NOW) with:

CURDATE()

You can also get the value of an item in the jObject like this:

JToken value;
if (json.TryGetValue(key, out value))
{
   DoSomething(value);
}

You can use SWITCH() function to evaluate multiple criteria to color the cell. The node <BackgroundColor> is the cell fill, <Color> is font color.

Expression:

=SWITCH(
    (
        Fields!Usage_Date.Value.Contains("TOTAL") 
        AND (Fields!User_Name.Value.Contains("TOTAL"))

I've collected info together:

• add into scope user_link, see https://developers.facebook.com/docs/facebook-login/permissions/
• add into fields request link (e.g. https://graph.facebook.com/me?fields=link,name,email)
• get link from answer. Be aware of field length- in my case it is 202: https://www.facebook.com/app_scoped_user_id/YXNpZADpBWEd0SlhFZAElYa3BQT3U3Tm4xWVRLSlJfYUdUM3Y4YmIwQjBaRkM0VDBMNURQdUhhYk5NRDJoR1ZA5ZA1JOdGNwampsSTQyMDQwbW93bkp0dnZAmOXg3NTFISFVZAQlRscWQ5eEZAvcU4xZAC1B/

And finaly: it doen't work without additional Facebook permission check:(

It works in a different way for variables copied by reference:

$a = 5;
$b = &$a;
unset($b); // just say $b should not point to any variable
print $a; // 5

$a = 5;
$b = &$a;
$b = null; // rewrites value of $b (and $a)
print $a; // nothing, because $a = null

You can do this:

And to capture locale. You can do this:

private static final String LOCALE = LocaleContextHolder.getLocale().getLanguage()
            + "-" + LocaleContextHolder.getLocale().getCountry();

If you can use BigDecimal, then use it, else:

/**
  *@param precision number of decimal digits
  */
public static boolean areEqualDouble(double a, double b, int precision) {
   return Math.abs(a - b) <= Math.pow(10, -precision);
}

The C++-canonical way: Don't check for errors...use the C++ bindings which throw exceptions.

I used to be irked by this problem; and I used to have a macro-cum-wrapper-function solution just like in Talonmies and Jared's answers, but, honestly? It makes using the CUDA Runtime API even more ugly and C-like.

So I've approached this in a different and more fundamental way. For a sample of the result, here's part of the CUDA vectorAdd sample - with complete error checking of every runtime API call:

// (... prepare host-side buffers here ...)

auto current_device = cuda::device::current::get();
auto d_A = cuda::memory::device::make_unique<float[]>(current_device, numElements);
auto d_B = cuda::memory::device::make_unique<float[]>(current_device, numElements);
auto d_C = cuda::memory::device::make_unique<float[]>(current_device, numElements);

cuda::memory::copy(d_A.get(), h_A.get(), size);
cuda::memory::copy(d_B.get(), h_B.get(), size);

// (... prepare a launch configuration here... )

cuda::launch(vectorAdd, launch_config,
    d_A.get(), d_B.get(), d_C.get(), numElements
);    
cuda::memory::copy(h_C.get(), d_C.get(), size);

// (... verify results here...)

Again - all potential errors are checked , and an exception if an error occurred (caveat: If the kernel caused some error after launch, it will be caught after the attempt to copy the result, not before; to ensure the kernel was successful you would need to check for error between the launch and the copy with a cuda::outstanding_error::ensure_none() command).

The code above uses my

Thin Modern-C++ wrappers for the CUDA Runtime API library (Github)

Note that the exceptions carry both a string explanation and the CUDA runtime API status code after the failing call.

A few links to how CUDA errors are automagically checked with these wrappers:

• A test program throwing and catching a bunch of exceptions
• Documentation for the error-related functionality

This is pretty straightforward using the File class.

if(File.Exists(@"C:\test.txt"))
{
    File.Delete(@"C:\test.txt");
}

Try

make clean
./configure --with-option=/path/etc
make && make install

This answer could be really late, but its useful.

You can play youtube videos in the app itself using android-youtube-player.

Some code snippets:

To play a youtube video that has a video id in the url, you simply call the OpenYouTubePlayerActivity intent

Intent intent = new Intent(null, Uri.parse("ytv://"+v), this, 
            OpenYouTubePlayerActivity.class);
startActivity(intent);

where v is the video id.

Add the following permissions in the manifest file:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

and also declare this activity in the manifest file:

<activity 
        android:name="com.keyes.youtube.OpenYouTubePlayerActivity"></activity>

Further information can be obtained from the first portions of this code file.

Hope that helps anyone!

This goes also for statements like this (auto-formatted by PyCharm):

    return combine_sample_generators(sample_generators['train']), \
           combine_sample_generators(sample_generators['dev']), \
           combine_sample_generators(sample_generators['test'])

Which will give the same style-warning. In order to get rid of it I had to rewrite it to:

    return \
        combine_sample_generators(sample_generators['train']), \
        combine_sample_generators(sample_generators['dev']), \
        combine_sample_generators(sample_generators['test'])

Have a look at the timeit module. It's not really equivalent but if the code you want to time is inside a function you can easily use it.

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?

here you can see NestedVM

NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.

Example: Cross compile Hello world C program and run it on android

it's really astounding to see such a heated discussion coming up when such a basic, valid and, i believe, mundane question is being asked.

some people have pointed out that type-checking against int (and long) might loose cases where a big decimal number is encountered. quite right.

some people have pointed out that you should 'just do x + 1 and see whether that fails. well, for one thing, this works on floats too, and, on the other hand, it's easy to construct a class that is definitely not very numeric, yet defines the + operator in some way.

i am at odds with many posts vigorously declaring that you should not check for types. well, GvR once said something to the effect that in pure theory, that may be right, but in practice, isinstance often serves a useful purpose (that's a while ago, don't have the link; you can read what GvR says about related issues in posts like this one).

what is funny is how many people seem to assume that the OP's intent was to check whether the type of a given x is a numerical integer type—what i understood is what i normally mean when using the OP's words: whether x represents an integer number. and this can be very important: like ask someone how many items they'd want to pick, you may want to check you get a non-negative integer number back. use cases like this abound.

it's also, in my opinion, important to see that (1) type checking is but ONE—and often quite coarse—measure of program correctness, because (2) it is often bounded values that make sense, and out-of-bounds values that make nonsense. sometimes just some intermittent values make sense—like considering all numbers, only those real (non-complex), integer numbers might be possible in a given case.

funny non-one seems to mention checking for x == math.floor( x ). if that should give an error with some big decimal class, well, then maybe it's time to re-think OOP paradigms. there is also PEP 357 that considers how to use not-so-obviously-int-but-certainly-integer-like values to be used as list indices. not sure whether i like the solution.

I generally use a small jQuery snippet globally to open any external links in a new tab / window. I've added the selector for a form for my own site and it works fine so far:

// URL target
    $('a[href*="//"]:not([href*="'+ location.hostname +'"]),form[action*="//"]:not([href*="'+ location.hostname +'"]').attr('target','_blank');

The CSS box model is rather complicated, particularly when it comes to scrolling content. While the browser uses the values from your CSS to draw boxes, determining all the dimensions using JS is not straight-forward if you only have the CSS.

That's why each element has six DOM properties for your convenience: offsetWidth, offsetHeight, clientWidth, clientHeight, scrollWidth and scrollHeight. These are read-only attributes representing the current visual layout, and all of them are integers (thus possibly subject to rounding errors).

Let's go through them in detail:

• offsetWidth, offsetHeight: The size of the visual box incuding all borders. Can be calculated by adding width/height and paddings and borders, if the element has display: block
• clientWidth, clientHeight: The visual portion of the box content, not including borders or scroll bars , but includes padding . Can not be calculated directly from CSS, depends on the system's scroll bar size.
• scrollWidth, scrollHeight: The size of all of the box's content, including the parts that are currently hidden outside the scrolling area. Can not be calculated directly from CSS, depends on the content.

Try it out: jsFiddle

Since offsetWidth takes the scroll bar width into account, we can use it to calculate the scroll bar width via the formula

scrollbarWidth = offsetWidth - clientWidth - getComputedStyle().borderLeftWidth - getComputedStyle().borderRightWidth

Unfortunately, we may get rounding errors, since offsetWidth and clientWidth are always integers, while the actual sizes may be fractional with zoom levels other than 1.

Note that this

scrollbarWidth = getComputedStyle().width + getComputedStyle().paddingLeft + getComputedStyle().paddingRight - clientWidth

does not work reliably in Chrome, since Chrome returns width with scrollbar already substracted. (Also, Chrome renders paddingBottom to the bottom of the scroll content, while other browsers don't)

To immediately flush call fflush(stdout) or fflush(NULL) (NULL means flush everything).

The command is lowercase: touch filename.

Keep in mind that touch will only create a new file if it does not exist! Here's some docs for good measure: http://unixhelp.ed.ac.uk/CGI/man-cgi?touch

If you always want an empty file, one way to do so would be to use:

echo "" > filename

You should have font-weight set to 900 for Font Awesome 5 Free font-family to work.

This is the working one:

.css-selector::before {
   font-family: 'Font Awesome 5 Free';
   content: "\f101";
   font-weight: 900;
}

You can go to for example C:\Python2.7\Scripts and then run cmd from that path. After that you can run pip2.7 install yourpackage...

That will install package for that version of Python.

First of all, Applets are designed to be run from within the context of a browser (or applet viewer), they're not really designed to be added into other containers.

Technically, you can add a applet to a frame like any other component, but personally, I wouldn't. The applet is expecting a lot more information to be available to it in order to allow it to work fully.

Instead, I would move all of the "application" content to a separate component, like a JPanel for example and simply move this between the applet or frame as required...

ps- You can use f.setLocationRelativeTo(null) to center the window on the screen ;)

Updated

You need to go back to basics. Unless you absolutely must have one, avoid applets until you understand the basics of Swing, case in point...

Within the constructor of GalzyTable2 you are doing...

JApplet app = new JApplet(); add(app); app.init(); app.start(); 

...Why are you adding another applet to an applet??

Case in point...

Within the main method, you are trying to add the instance of JFrame to itself...

f.getContentPane().add(f, button2); 

Instead, create yourself a class that extends from something like JPanel, add your UI logical to this, using compound components if required.

Then, add this panel to whatever top level container you need.

Use the M0Rf30/android-udev-rules GitHub community maintained udev-rules

https://github.com/M0Rf30/android-udev-rules/blob/master/51-android.rules

This is the most complete udev-rules list I've seen so far, even more than the currently recommended sudo apt-get install android-tools-adb on the official documentation, and it solved that problem for me.

You can use private as well and you can call private methods with reflection. If you're using Visual Studio Team Suite it has some nice functionality that will generate a proxy to call your private methods for you. Here's a code project article that demonstrates how you can do the work yourself to unit test private and protected methods:

http://www.codeproject.com/KB/cs/testnonpublicmembers.aspx

In terms of which access modifier you should use, my general rule of thumb is start with private and escalate as needed. That way you will expose as little of the internal details of your class as are truly needed and it helps keep the implementation details hidden, as they should be.

Goto PhoneGapTest>>platform Then delete the folder ios after that go to terminal then type: sudo phonegap build ios after that you can run the project

In case others have the same issue:

I had a similar error happening. turned out I was wrapping several SQL statements in a transactions, where one of them executed on a linked server (Merge statement in an EXEC(...) AT Server statement). I resolved the issue by opening a separate connection to the linked server, encapsulating that statement in a try...catch then abort the transaction on the original connection in case the catch is tripped.

You can use following syntax, For more information see this question and answers : Add a column with a default value to an existing table in SQL Server

Syntax :

ALTER TABLE {TABLENAME} 
ADD {COLUMNNAME} {TYPE} {NULL|NOT NULL} 
CONSTRAINT {CONSTRAINT_NAME} DEFAULT {DEFAULT_VALUE}
WITH VALUES

Example :

ALTER TABLE SomeTable
ADD SomeCol Bit NULL --Or NOT NULL.
CONSTRAINT D_SomeTable_SomeCol --When Omitted a Default-Constraint Name is 
autogenerated.
DEFAULT (0)--Optional Default-Constraint.
WITH VALUES --Add if Column is Nullable and you want the Default Value for Existing Records.

Another way :

Right click on the table and click on Design,then click on column that you want to set default value.

Then in bottom of page add a default value or binding : something like '1' for string or 1 for int.

Foreign keys are almost always "Allow Duplicates," which would make them unsuitable as Primary Keys.

Instead, find a field that uniquely identifies each record in the table, or add a new field (either an auto-incrementing integer or a GUID) to act as the primary key.

The only exception to this are tables with a one-to-one relationship, where the foreign key and primary key of the linked table are one and the same.

You could use simple regex:

var result = fileAsString.replace(/string to be replaced/g, 'replacement');

So...

var fs = require('fs')
fs.readFile(someFile, 'utf8', function (err,data) {
  if (err) {
    return console.log(err);
  }
  var result = data.replace(/string to be replaced/g, 'replacement');

  fs.writeFile(someFile, result, 'utf8', function (err) {
     if (err) return console.log(err);
  });
});

You have to add an OnItemClickListener to the listview to determine which item was clicked, then find the checkbox.

mListView.setOnItemClickListener(new OnItemClickListener()
{
    @Override
    public void onItemClick(AdapterView<?> parent, View v, int position, long id)
    {
        CheckBox cb = (CheckBox) v.findViewById(R.id.checkbox_id);
    }
});

undefined index means the array key is not set , do a var_dump($_POST);die(); before the line that throws the error and see that you're trying to get an array key that does not exist.

I am not familiar with, react-table, so I do not know it has direct support for selecting and deselecting (it would be nice if it had).

If it does not, with the piece of code you already have you can install the onCLick handler. Now instead of trying to attach style directly to row, you can modify state, by for instance adding selected: true to row data. That would trigger rerender. Now you only have to override how are rows with selected === true rendered. Something along lines of:

// Any Tr element will be green if its (row.age > 20) 
<ReactTable
  getTrProps={(state, rowInfo, column) => {
    return {
      style: {
        background: rowInfo.row.selected ? 'green' : 'red'
      }
    }
  }}
/>

It looks like you were on the right track - get_FOO_display() is most certainly what you want:

In templates, you don't include () in the name of a method. Do the following:

{{ person.get_gender_display }}

You can check it by connecting MySQL through the command prompt.

I think that your MySQL Database is blocked by firewall. Once stop all the services of antivirus software you have on your computer, then try to connect.

I faced this problem as well and rectified by blocking all firewalls..

$ unset GOROOT worked for me. As most answers suggest your GOROOT is invalid.

I have had an issue using Bootstrap where using double quotes did matter vs using single quote (which didn't work). class='row-fluid' gave me issues causing the last span to fall below the other spans rather than sitting nicely beside on the far right, whereas class="row-fluid" worked.

Douglas Crockford says:

type="text/javascript"

This attribute is optional. Since Netscape 2, the default programming language in all browsers has been JavaScript. In XHTML, this attribute is required and unnecessary. In HTML, it is better to leave it out. The browser knows what to do.

He also says:

W3C did not adopt the language attribute, favoring instead a type attribute which takes a MIME type. Unfortunately, the MIME type was not standardized, so it is sometimes "text/javascript" or "application/ecmascript" or something else. Fortunately, all browsers will always choose JavaScript as the default programming language, so it is always best to simply write <script>. It is smallest, and it works on the most browsers.

For entertainment purposes only, I tried out the following five scripts

  <script type="application/ecmascript">alert("1");</script>
  <script type="text/javascript">alert("2");</script>
  <script type="baloney">alert("3");</script>
  <script type="">alert("4");</script>
  <script >alert("5");</script>

On Chrome, all but script 3 (type="baloney") worked. IE8 did not run script 1 (type="application/ecmascript") or script 3. Based on my non-extensive sample of two browsers, it looks like you can safely ignore the type attribute, but that it you use it you better use a legal (browser dependent) value.

You can apply any one approach:

$("#Input_Id").change(function(){   // 1st
    // do your code here
    // When your element is already rendered
});


$("#Input_Id").on('change', function(){    // 2nd (A)
    // do your code here
    // It will specifically called on change of your element
});

$("body").on('change', '#Input_Id', function(){    // 2nd (B)
    // do your code here
    // It will filter the element "Input_Id" from the "body" and apply "onChange effect" on it
});

You're doing only one mistake.

use replaceAll() function over there.

e.g.

String str = "Hi";
String str1 = "hello";
str.replaceAll( str, str1 );

An example usage:

>>> s = 'Hello world'
>>> t = buffer(s, 6, 5)
>>> t
<read-only buffer for 0x10064a4b0, size 5, offset 6 at 0x100634ab0>
>>> print t
world

The buffer in this case is a sub-string, starting at position 6 with length 5, and it doesn't take extra storage space - it references a slice of the string.

This isn't very useful for short strings like this, but it can be necessary when using large amounts of data. This example uses a mutable bytearray:

>>> s = bytearray(1000000)   # a million zeroed bytes
>>> t = buffer(s, 1)         # slice cuts off the first byte
>>> s[1] = 5                 # set the second element in s
>>> t[0]                     # which is now also the first element in t!
'\x05'

This can be very helpful if you want to have more than one view on the data and don't want to (or can't) hold multiple copies in memory.

Note that buffer has been replaced by the better named memoryview in Python 3, though you can use either in Python 2.7.

Note also that you can't implement a buffer interface for your own objects without delving into the C API, i.e. you can't do it in pure Python.

Check the apache User and Group setting in the httpd.conf. It should default to apache on AMI/RedHat or www-data on Debian.

grep '^Group\|^User' /etc/httpd/conf/httpd.conf

Then add the apache user to the group setting of your site's root directory.

sudo usermod -a -G <your-site-root-dir-group> apache

This function generates random string consisting of upper,lowercase letters, digits, pass the length seperator, no_of_blocks to specify your string format

eg: len_sep = 4, no_of_blocks = 4 will generate the following pattern,

F4nQ-Vh5z-JKEC-WhuS

Where, length seperator will add "-" after 4 characters

XXXX-

no of blocks will generate the following patten of characters as string

XXXX - XXXX - XXXX - XXXX

if a single random string is needed, just keep the no_of_blocks variable to be equal to 1 and len_sep to specify the length of the random string.

eg: len_sep = 10, no_of_blocks = 1, will generate the following pattern ie. random string of length 10,

F01xgCdoDU

import random as r

def generate_random_string(len_sep, no_of_blocks):
    random_string = ''
    random_str_seq = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
    for i in range(0,len_sep*no_of_blocks):
        if i % len_sep == 0 and i != 0:
            random_string += '-'
        random_string += str(random_str_seq[r.randint(0, len(random_str_seq) - 1)])
    return random_string

adb shell
su
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system

This assumes your /system is yaffs2 and that it's at /dev/block/mtdblock3 the easier/better way to do this on most Android phones is:

adb shell
su
mount -o remount,rw /system

Done. This just says remount /system read-write, you don't have to specify filesystem or mount location.

This should do the job

//get a reference to the canvas
var ctx = $('#canvas')[0].getContext("2d");

//draw a dot
ctx.beginPath();
ctx.arc(20, 20, 10, 0, Math.PI*2, true);
ctx.closePath();
ctx.fill();

This may work for you

grep -E '(^|\s)OK($|\s)'

HTML

<input type="text" id="youridher" size="10">

Use JQuery,

SIZE = 10
$(document).ready(function() {
      $("#youridher").bind('keyup', function() { 
            if($("#youridher").val().length <= SIZE && PHONE_REGEX) {
                return true;
            }
            else {
                return false;
            }  
      });
});

You can use Collections.swap(List<?> list, int i, int j);

You can download a list of CA certificates from curl's website at http://curl.haxx.se/ca/cacert.pem

Then set the SSL_CERT_FILE environment variable to tell Ruby to use it. For example, in Linux:

$ SSL_CERT_FILE=~/cacert.pem bundle install

In TypeScript, you can do:

private getImage(imagePath): ng.IPromise<any> {
    var defer = this.q.defer<any>();
    var img = new Image();
    img.src = imagePath;
    img.addEventListener('load',()=>{
       defer.resolve(img);
    });


    return defer.promise;
} 

Use the above function to getimage object. Then the following to add to pdf file:

pdf.addImage(getImage(url), 'png', x, y, imagewidth, imageheight);

In plain JavaScript, the function looks like this:

function (imagePath) {
        var defer = this.q.defer();
        var img = new Image();
        img.src = imagePath;
        img.addEventListener('load', function () {
            defer.resolve(img);
        });
        return defer.promise;
    };

The cause if had for this problem was IIS Express not allowing WindowsAuthentication. This can be enabled by setting

<windowsAuthentication enabled="true">

in the applicationhost.config file located at C:\Users[username]\Documents\IISExpress\config.

There is no easy way to do multiple class inheritance. I follow the combination of association and inheritance to achieve this kind of behavior.

    class Person {
        constructor(firstname, lastname, age){
            this.firstname = firstname,
            this.lastname = lastname
            this.Age = age
        }

        fullname(){
                return this.firstname +" " + this.lastname;
            } 
    }

    class Organization {
        constructor(orgname){
            this.orgname = orgname;
        }
    }

    class Employee extends Person{
        constructor(firstname, lastname, age,id) {
            super(firstname, lastname, age);
            this.id = id;
        }

    }
    var emp = new Employee("John", "Doe", 33,12345);
    Object.assign(emp, new Organization("Innovate"));
    console.log(emp.id);
    console.log(emp.orgname);
    console.log(emp.fullname());

Hope this is helpful.

Try adding this in your vhost config:

RewriteEngine On
RewriteRule ^(.*)$ https://%{HTTP_HOST}$1 [R=301,L]

I had the same problem because i had an old version of Virtual Box (4.0.0).
So, I uninstalled genymotion and the old version of VB,
and I installed genymotion with virtual box (5.0.28).
And Its worked fine.

Generate a file from the string of your folder directory

String path="Folder directory";    
File file = new File(path);

and use method exist.
If you want to generate the folder you sould use mkdir()

if (!file.exists()) {
            System.out.print("No Folder");
            file.mkdir();
            System.out.print("Folder created");
        }

select <column list> into <dest. table> from <source table>;

You could do this way.

SELECT windows_release, windows_service_pack_level, 
       windows_sku, os_language_version
into   new_table_name
FROM   sys.dm_os_windows_info OPTION (RECOMPILE);

Another example using COALESCE. http://sqlmag.com/t-sql/coalesce-vs-isnull

SELECT (COALESCE(SUM(val1),0) + COALESCE(SUM(val2), 0)
+ COALESCE(SUM(val3), 0) + COALESCE(SUM(val4), 0)) AS 'TOTAL'
FROM Emp

}
</script>

Codes starting with 4 (4xx) are meant for client errors. Maybe 400 (Bad Request) could be suitable to this case? Definition in http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html says:

"The request could not be understood by the server due to malformed syntax. The client SHOULD NOT repeat the request without modifications. "

Ends an iterator block (e.g. says there are no more elements in the IEnumerable).

From the Javadoc of Method.invoke()

Throws: InvocationTargetException - if the underlying method throws an exception.

This exception is thrown if the method called threw an exception.

It is never a good idea to break out of a for-loop. If you are using a for-loop it means that you know how many times you want to iterate. Use a while-loop with 2 conditions.

for example

var done = false
while (i <= length && !done) {
  if (sum > 1000) {
     done = true
  }
}

use setAttribute() and removeAttribute()

function disbtn(e) { 
    if ( someCondition == true ) {
       document.getElementById('btn1').setAttribute("disabled","disabled");
    } else {
       document.getElementById('btn1').removeAttribute("disabled");
    }
}

I had a similar question, but was actually looking for a different answer; I'm looking to create a custom event. For example instead of always saying this:

$('#myInput').keydown(function(ev) {
    if (ev.which == 13) {
        ev.preventDefault();
        // Do some stuff that handles the enter key
    }
});

I want to abbreviate it to this:

$('#myInput').enterKey(function() {
    // Do some stuff that handles the enter key
});

trigger and bind don't tell the whole story - this is a JQuery plugin. http://docs.jquery.com/Plugins/Authoring

The "enterKey" function gets attached as a property to jQuery.fn - this is the code required:

(function($){
    $('body').on('keydown', 'input', function(ev) {
        if (ev.which == 13) {
            var enterEv = $.extend({}, ev, { type: 'enterKey' });
            return $(ev.target).trigger(enterEv);
        }
    });

    $.fn.enterKey = function(selector, data, fn) {
        return this.on('enterKey', selector, data, fn);
    };
})(jQuery);

http://jsfiddle.net/b9chris/CkvuJ/4/

A nicety of the above is you can handle keyboard input gracefully on link listeners like:

$('a.button').on('click enterKey', function(ev) {
    ev.preventDefault();
    ...
});

Edits: Updated to properly pass the right this context to the handler, and to return any return value back from the handler to jQuery (for example in case you were looking to cancel the event and bubbling). Updated to pass a proper jQuery event object to handlers, including key code and ability to cancel event.

You will achive it with setting property Anchor: None.

You should be careful about using the finally block, as it is not the same thing as using an else block in the try, except. The finally block will be run regardless of the outcome of the try except.

In [10]: dict_ = {"a": 1}

In [11]: try:
   ....:     dict_["b"]
   ....: except KeyError:
   ....:     pass
   ....: finally:
   ....:     print "something"
   ....:     
something

As everyone has noted using the else block causes your code to be more readable, and only runs when an exception is not thrown

In [14]: try:
             dict_["b"]
         except KeyError:
             pass
         else:
             print "something"
   ....:

Many say it is not possible, I would go one step further and say it is not meaningfull.

A static member is something that does not relate to any instance, only to the class.

A virtual member is something that does not relate directly to any class, only to an instance.

So a static virtual member would be something that does not relate to any instance or any class.

Use Keytool binary or exe to generate a private keystore. Instructions here. You can then sign your app using this keystore. Keytool gets installed when you install Java.

NOTE: Save/backup this keystore because once you publish an app on play by signing it with this keystore, you will have to use the same keystore for any future updates. So, it's important that you back it up.

HTH.

char c = '5'

A char (1 byte) is allocated on stack at address 0x12345678.

char *d = &c;

You obtain the address of c and store it in d, so d = 0x12345678.

int *e = (int*)d;

You force the compiler to assume that 0x12345678 points to an int, but an int is not just one byte (sizeof(char) != sizeof(int)). It may be 4 or 8 bytes according to the architecture or even other values.

So when you print the value of the pointer, the integer is considered by taking the first byte (that was c) and other consecutive bytes which are on stack and that are just garbage for your intent.

if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then

You keep on getting new a new string and continue the loop if it's not empty. Simply insert a control in the loop for an exit string.

while(!s1.equals("exit") && sc.hasNext()) {
    // operate
}

If you want to declare the string inside the loop and not to do the operations in the loop body if the string is "exit":

while(sc.hasNext()) {
    String s1 = sc.next();
    if(s1.equals("exit")) {
        break;
    }
    //operate
}

1. Go to setting app.
2. Click Storage & USB.
3. Click Phone Card.
4. Click Android.
5. Click Data.

Tries, also known as prefix-trees or crit-bit trees, have existed for over 40 years but are still relatively unknown. A very cool use of tries is described in "TRASH - A dynamic LC-trie and hash data structure", which combines a trie with a hash function.

JavaScript has a RegExp object which does what you want. The String object has a match() function that will help you out.

var matches = text.match(/price\[(\d+)\]\[(\d+)\]/);
var productId = matches[1];
var shopId    = matches[2];

When I used above code.It show me translated text as question mark like (???????).Then I convert from WebClient to HttpClient then I got a accurate result.So you can used code like this.

public static string TranslateText( string input, string languagePair)       
{
    string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
    HttpClient httpClient = new HttpClient();
    string result = httpClient.GetStringAsync(url).Result;
    result = result.Substring(result.IndexOf("<span title=\"") + "<span title=\"".Length);
    result = result.Substring(result.IndexOf(">") + 1);
    result = result.Substring(0, result.IndexOf("</span>"));
    return result.Trim();
}

Then you Call a function like.You put first two letter of any language pair.

From English(en) To Urdu(ur).

TranslateText(line, "en|ur")

In your situation you got a reference to the missing symbols. But in some situations, ld will not provide error information.

If you want to expand the information provided by ld, just add the following parameters to your $(LDFLAGS)

-Wl,-V

StringBuilder will perform replace more efficiently, since its character array buffer can be specified to a required length.StringBuilder is designed for more than appending!

Of course the real question is whether this is an optimisation too far ? The JVM is very good at handling creation of multiple objects and the subsequent garbage collection, and like all optimisation questions, my first question is whether you've measured this and determined that it's a problem.

Alternatively, in situations where I want to return a number of things from a method I will sometimes use a callback mechanism instead of a container. This works very well in situations where I cannot specify ahead of time just how many objects will be generated.

With your particular problem, it would look something like this:

public class ResultsConsumer implements ResultsGenerator.ResultsCallback
{
    public void handleResult( String name, Object value )
    {
        ... 
    }
}

public class ResultsGenerator
{
    public interface ResultsCallback
    {
        void handleResult( String aName, Object aValue );
    }

    public void generateResults( ResultsGenerator.ResultsCallback aCallback )
    {
        Object value = null;
        String name = null;

        ...

        aCallback.handleResult( name, value );
    }
}

Yes, if bar is not None is more explicit, and thus better, assuming it is indeed what you want. That's not always the case, there are subtle differences: if not bar: will execute if bar is any kind of zero or empty container, or False. Many people do use not bar where they really do mean bar is not None.

I believe this is what you're looking for. It automatically scaled the video to fit the container.

A layman response would be that it is a function that is not called by you but rather by the user or by the browser after a certain event has happened or after some code has been processed.

The command (or the URL in it) to add the github repository as a remote isn't quite correct. If I understand your repository name correctly, it should be;

git remote add demo_app '[email protected]:levelone/demo_app.git'

string result = System.Text.Encoding.UTF8.GetString(fs.ToArray());

Angular is based on observable instead of promise base as of angularjs 1.x, so when we try to get data using http it returns observable instead of promise, like you did

 return this.http
      .get(this.configEndPoint)
      .map(res => res.json());

then to get data and show on view we have to convert it into desired form using RxJs functions like .map() function and .subscribe()

.map() is used to convert the observable (received from http request)to any form like .json(), .text() as stated in Angular's official website,

.subscribe() is used to subscribe those observable response and ton put into some variable so from which we display it into the view

this.myService.getConfig().subscribe(res => {
   console.log(res);
   this.data = res;
});

If you really need to do this, use reverse proxy.

For example, with nginx as reverse proxy

server {
  listen       api.mydomain.com:80;
  server_name  api.mydomain.com;
  location / {
    proxy_pass http://127.0.0.1:8000;
  }
}

It is the version key.It gets updated whenever a new update is made. I personally don't like to disable it .

Read this solution if you want to know more [1]: Mongoose versioning: when is it safe to disable it?

I found this shorter and much better:

    if(varName !== (undefined || null)) { //do something }

This will do it:

declare @UNIX_TIME int
select @UNIX_TIME = 1111111111
-- Using dateadd to add seconds to 1970-01-01
select [Datetime from UNIX Time] = dateadd(!precision!,@UNIX_TIME,'1970-01-01')

Instead of !precision! use: ss,ms or mcs according to the precision of the timestamp. Bigint is capable to hold microsecond precision.

You can try this :-

AlterDialog alterdialog;
alertDialog.setCanceledOnTouchOutside(true);

or

alertDialog.setCancelable(true);

And if you have a AlterDialog.Builder Then you can try this:-

alertDialogBuilder.setCancelable(true);

I found this example Generate random numbers :

This example generates random integers in a specific range.

import java.util.Random;

/** Generate random integers in a certain range. */
public final class RandomRange {

  public static final void main(String... aArgs){
    log("Generating random integers in the range 1..10.");

    int START = 1;
    int END = 10;
    Random random = new Random();
    for (int idx = 1; idx <= 10; ++idx){
      showRandomInteger(START, END, random);
    }

    log("Done.");
  }

  private static void showRandomInteger(int aStart, int aEnd, Random aRandom){
    if ( aStart > aEnd ) {
      throw new IllegalArgumentException("Start cannot exceed End.");
    }
    //get the range, casting to long to avoid overflow problems
    long range = (long)aEnd - (long)aStart + 1;
    // compute a fraction of the range, 0 <= frac < range
    long fraction = (long)(range * aRandom.nextDouble());
    int randomNumber =  (int)(fraction + aStart);    
    log("Generated : " + randomNumber);
  }

  private static void log(String aMessage){
    System.out.println(aMessage);
  }
} 

An example run of this class :

Converting and removing annoying stars:

$array = (array) $object;
foreach($array as $key => $val)
{
    $new_array[str_replace('*_', '', $key)] = $val;
}

Probably, it will be cheaper than using reflections.

$('#submenu li').hover(function(){
    $('#carousel').css('backgroundPosition', newValue);
});

'a' in x

and a quick search reveals some nice information about it: http://docs.python.org/3/tutorial/datastructures.html#dictionaries

This feature has been added to node.js in version 10.12.0, so it's as easy as passing an option {recursive: true} as second argument to the fs.mkdir() call. See the example in the official docs.

No need for external modules or your own implementation.

I had success using .on() like so:

$('.leadtoscore').on('click', {event_type: 'shot'}, add_event);

Then inside the add_event function you get access to 'shot' like this:

event.data.event_type

See the .on() documentation for more info, where they provide the following example:

function myHandler( event ) {
  alert( event.data.foo );
}
$( "p" ).on( "click", { foo: "bar" }, myHandler );

In file /etc/ssh/sshd_config

# Change to no to disable tunnelled clear text passwords
#PasswordAuthentication no

Uncomment the second line, and, if needed, change yes to no.

Then run

service ssh restart

So as to have another possibility¹ to find the files that are executable by the current user:

find . -type f -exec test -x {} \; -print

(the test command here is the one found in PATH, very likely /usr/bin/test, not the builtin).

¹ Only use this if the -executable flag of find is not available! this is subtly different from the -perm +111 solution.

Here's a one-liner using Maven:

mvn dependency:get -Dartifact=mysql:mysql-connector-java:5.1.38

Then, with default settings, it's available in:

$HOME/.m2/repository/mysql/mysql-connector-java/5.1.38/mysql-connector-java-5.1.38.jar

Just replace the version number if you need a different one.

You want to see the entire object (all nested levels of objects and variables inside it) in JSON form. JSON stands for JavaScript Object Notation, and printing out a JSON string of your object is a good equivalent of var_dump (to get a string representation of a JavaScript object). Fortunately, JSON is very easy to use in code, and the JSON data format is also pretty human-readable.

Example:

var objectInStringFormat = JSON.stringify(someObject);
alert(objectInStringFormat);

$this->db->select('overal_points');
$this->db->where('point_publish', 1);
$this->db->order_by('overal_points', 'desc'); 
$query = $this->db->get('company', 4)->result();

That's not what map does. You really want Array.filter. Or if you really want to remove the elements from the original list, you're going to need to do it imperatively with a for loop.

Object.keys(myObj).length === 0;

As there is need to just check if Object is empty it will be better to directly call a native method Object.keys(myObj).length which returns the array of keys by internally iterating with for..in loop.As Object.hasOwnProperty returns a boolean result based on the property present in an object which itself iterates with for..in loop and will have time complexity O(N2).

On the other hand calling a UDF which itself has above two implementations or other will work fine for small object but will block the code which will have severe impact on overall perormance if Object size is large unless nothing else is waiting in the event loop.

Your problem can be caused by different things. I will provide you three possible scenarios in Linux:

• The File location

When you use scp name , you mean that your File name is in Home directory. When it is in Home but inside in another Folder, for example, my_folder, you should write:

scp /home/my-username/my_folder/name [email protected]:/Path....

• You File Permission

You must know the File Permission your File has. If you have Read-only you should change it.

To change the Permission:

As Root ,sudo caja ( the default file manager for the MATE Desktop) or another file manager ,then with you Mouse , right-click to the File name , select Properties + Permissions and change it on Group and Other to Read and write .

Or with chmod .

• You Port Number

Maybe you remote machine or Server can only communicate with a Port Number, so you should write -P and the Port Number.

scp -P 22 /home/my-username/my_folder/name [email protected] /var/www/html

I modified @LcSalazar's answer a bit... it's still not perfect because the background of the default buttons can still be seen in both Firefox, Chrome & Opera (not tested in Safari); but clicking on the arrows still works

Notes:

• Adding pointer-events: none; allows you to click through the overlapping button, but then you can not style the button while hovered.
• The arrows are visible in Edge, but don't work because Edge doesn't use arrows. It only adds an "x" to clear the input.

Because C, where the concept originated, is 30 years old, and back then, it was the only viable way to link together code from multiple files.

Today, it's an awful hack which totally destroys compilation time in C++, causes countless needless dependencies (because class definitions in a header file expose too much information about the implementation), and so on.

You need to edit the Tomcat/conf/server.xml and change the connector port. The connector setting should look something like this:

<Connector port="8080" maxHttpHeaderSize="8192"
           maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
           enableLookups="false" redirectPort="8443" acceptCount="100"
           connectionTimeout="20000" disableUploadTimeout="true" />

Just change the connector port from default 8080 to another valid port number.

This is tailored to finding formulas but you should be able to expand it to general content by altering how you test the starting cells. You'll have to handle single cell ranges outside of this.

    public static Range GetUsedPartOfRange(this Range range)
    {
        Excel.Range beginCell = range.Cells[1, 1];
        Excel.Range endCell = range.Cells[range.Rows.Count, range.Columns.Count];

        if (!beginCell.HasFormula)
        {
            var beginCellRow = range.Find(
                "*",
                beginCell,
                XlFindLookIn.xlFormulas,
                XlLookAt.xlPart,
                XlSearchOrder.xlByRows,
                XlSearchDirection.xlNext,
                false);

            var beginCellCol = range.Find(
                "*",
                beginCell,
                XlFindLookIn.xlFormulas,
                XlLookAt.xlPart,
                XlSearchOrder.xlByColumns,
                XlSearchDirection.xlNext,
                false);

            if (null == beginCellRow || null == beginCellCol)
                return null;

            beginCell = range.Worksheet.Cells[beginCellRow.Row, beginCellCol.Column];
        }

        if (!endCell.HasFormula)
        {
            var endCellRow = range.Find(
            "*",
            endCell,
            XlFindLookIn.xlFormulas,
            XlLookAt.xlPart,
            XlSearchOrder.xlByRows,         
            XlSearchDirection.xlPrevious,
            false);

            var endCellCol = range.Find(
                "*",
                endCell,
                XlFindLookIn.xlFormulas,
                XlLookAt.xlPart,
                XlSearchOrder.xlByColumns,
                XlSearchDirection.xlPrevious,
                false);

            if (null == endCellRow || null == endCellCol)
                return null;

            endCell = range.Worksheet.Cells[endCellRow.Row, endCellCol.Column];
        }

        if (null == endCell || null == beginCell)
            return null;

        Excel.Range finalRng = range.Worksheet.Range[beginCell, endCell];

        return finalRng;
    }
}

To make the whole div act as a link, set the anchor tag as:

display: block

And set your height of the anchor tag to 100%. Then set a fixed height to your div tag. Then style your anchor tag like usual.

For example:

<html>
<head>
    <title>DIV Link</title>

    <style type="text/css">
    .link-container {
        border: 1px solid;
        width: 50%;
        height: 20px;
    }

    .link-container a {
        display: block;
        background: #c8c8c8;
        height: 100%;
        text-align: center;
    }

    .link-container a:hover {
        background: #f8f8f8;
    }

    </style>

</head>
<body>

    <div class="link-container">
        <a href="http://www.stackoverflow.com">Stack Overflow</a>
    </div>

    <div class="link-container">
        <a href="http://www.stackoverflow.com">Stack Overflow</a>
    </div>

</body> </html>

Good luck!

Serializable

Serializable is a markable interface or we can call as an empty interface. It doesn’t have any pre-implemented methods. Serializable is going to convert an object to byte stream. So the user can pass the data between one activity to another activity. The main advantage of serializable is the creation and passing data is very easy but it is a slow process compare to parcelable.

Parcelable

Parcel able is faster than serializable. Parcel able is going to convert object to byte stream and pass the data between two activities. Writing parcel able code is little bit complex compare to serialization. It doesn’t create more temp objects while passing the data between two activities.

There are two options:

Using Imports

This is the suggested option. It ensures your fonts go through the build pipeline, get hashes during compilation so that browser caching works correctly, and that you get compilation errors if the files are missing.

As described in “Adding Images, Fonts, and Files”, you need to have a CSS file imported from JS. For example, by default src/index.js imports src/index.css:

import './index.css';

A CSS file like this goes through the build pipeline, and can reference fonts and images. For example, if you put a font in src/fonts/MyFont.woff, your index.css might include this:

@font-face {
  font-family: 'MyFont';
  src: local('MyFont'), url(./fonts/MyFont.woff) format('woff');
}

Notice how we’re using a relative path starting with ./. This is a special notation that helps the build pipeline (powered by Webpack) discover this file.

Normally this should be enough.

Using public Folder

If for some reason you prefer not to use the build pipeline, and instead do it the “classic way”, you can use the public folder and put your fonts there.

The downside of this approach is that the files don’t get hashes when you compile for production so you’ll have to update their names every time you change them, or browsers will cache the old versions.

If you want to do it this way, put the fonts somewhere into the public folder, for example, into public/fonts/MyFont.woff. If you follow this approach, you should put CSS files into public folder as well and not import them from JS because mixing these approaches is going to be very confusing. So, if you still want to do it, you’d have a file like public/index.css. You would have to manually add <link> to this stylesheet from public/index.html:

<link rel="stylesheet" href="%PUBLIC_URL%/index.css">

And inside of it, you would use the regular CSS notation:

@font-face {
  font-family: 'MyFont';
  src: local('MyFont'), url(fonts/MyFont.woff) format('woff');
}

Notice how I’m using fonts/MyFont.woff as the path. This is because index.css is in the public folder so it will be served from the public path (usually it’s the server root, but if you deploy to GitHub Pages and set your homepage field to http://myuser.github.io/myproject, it will be served from /myproject). However fonts are also in the public folder, so they will be served from fonts relatively (either http://mywebsite.com/fonts or http://myuser.github.io/myproject/fonts). Therefore we use the relative path.

Note that since we’re avoiding the build pipeline in this example, it doesn’t verify that the file actually exists. This is why I don’t recommend this approach. Another problem is that our index.css file doesn’t get minified and doesn’t get a hash. So it’s going to be slower for the end users, and you risk the browsers caching old versions of the file.

 Which Way to Use?

Go with the first method (“Using Imports”). I only described the second one since that’s what you attempted to do (judging by your comment), but it has many problems and should only be the last resort when you’re working around some issue.

This can be done with standard java properties in combination with the maven-resource-plugin with enabled filtering on properties.

For more info see http://maven.apache.org/plugins/maven-resources-plugin/examples/filter.html

This will work for standard maven project as for plugin projects

You have to define the text color in the layout *simple_list_item_1* that defines the layout of each of your items.

You set the background color of the LinearLayout and not of the ListView. The background color of the child items of the LinearLayout are transparent by default (in most cases).

And you set the black text color for the TextView that is not part of your ListView. It is an own item (child item of the LinearLayout) here.

You can use std::reverse like this

std::reverse(str.begin(), str.end());

Simple way which i found is,

In servlet:

You can set the value and forward it to JSP like below

req.setAttribute("myname",login);
req.getRequestDispatcher("welcome.jsp").forward(req, resp); 

In Welcome.jsp you can get the values by

.<%String name = (String)request.getAttribute("myname"); %>
<%= name%>

(or) directly u can call

<%= request.getAttribute("myname") %>.

It looks like you are running something in Windows by double clicking on it. This will execute the program in a new window and close the window when it terminates. No wonder you cannot read the output.

A better way to do this would be to switch to the command prompt. Navigate (cd) to the directory where the program is located and then call it using python. Something like this:

C:\> cd C:\my_programs\
C:\my_programs\> python area.py

Replace my_programs with the actual location of your program and area.py with the name of your python file.

When you get a UnicodeEncodeError, it means that somewhere in your code you convert directly a byte string to a unicode one. By default in Python 2 it uses ascii encoding, and utf8 encoding in Python3 (both may fail because not every byte is valid in either encoding)

To avoid that, you must use explicit decoding.

If you may have 2 different encoding in your input file, one of them accepts any byte (say UTF8 and Latin1), you can try to first convert a string with first and use the second one if a UnicodeDecodeError occurs.

def robust_decode(bs):
    '''Takes a byte string as param and convert it into a unicode one.
First tries UTF8, and fallback to Latin1 if it fails'''
    cr = None
    try:
        cr = bs.decode('utf8')
    except UnicodeDecodeError:
        cr = bs.decode('latin1')
    return cr

If you do not know original encoding and do not care for non ascii character, you can set the optional errors parameter of the decode method to replace. Any offending byte will be replaced (from the standard library documentation):

Replace with a suitable replacement character; Python will use the official U+FFFD REPLACEMENT CHARACTER for the built-in Unicode codecs on decoding and ‘?’ on encoding.

bs.decode(errors='replace')

The native DOM method does the right thing:

$('.cssbuttongo')[0].click();
                  ^
              Important!

This works regardless of whether the href is a URL, a fragment (e.g. #blah) or even a javascript:.

Note that this calls the DOM click method instead of the jQuery click method (which is very incomplete and completely ignores href).

expr(1) has a substr subcommand:

expr substr <string> <start-index> <length>

This may be useful if you don't have bash (perhaps embedded Linux) and you don't want the extra "echo" process you need to use cut(1).

if($("h1").is(":hidden")){
    // your code..
}

Why don't you just save/serve the CSS file as UTF-8?

nav a:hover:after {
    content: "?";
}

If that's not good enough, and you want to keep it all-ASCII:

nav a:hover:after {
    content: "\2193";
}

The general format for a Unicode character inside a string is \000000 to \FFFFFF – a backslash followed by six hexadecimal digits. You can leave out leading 0 digits when the Unicode character is the last character in the string or when you add a space after the Unicode character. See the spec below for full details.

Relevant part of the CSS2 spec:

Third, backslash escapes allow authors to refer to characters they cannot easily put in a document. In this case, the backslash is followed by at most six hexadecimal digits (0..9A..F), which stand for the ISO 10646 ([ISO10646]) character with that number, which must not be zero. (It is undefined in CSS 2.1 what happens if a style sheet does contain a character with Unicode codepoint zero.) If a character in the range [0-9a-fA-F] follows the hexadecimal number, the end of the number needs to be made clear. There are two ways to do that:

1. with a space (or other white space character): "\26 B" ("&B"). In this case, user agents should treat a "CR/LF" pair (U+000D/U+000A) as a single white space character.
2. by providing exactly 6 hexadecimal digits: "\000026B" ("&B")

In fact, these two methods may be combined. Only one white space character is ignored after a hexadecimal escape. Note that this means that a "real" space after the escape sequence must be doubled.

If the number is outside the range allowed by Unicode (e.g., "\110000" is above the maximum 10FFFF allowed in current Unicode), the UA may replace the escape with the "replacement character" (U+FFFD). If the character is to be displayed, the UA should show a visible symbol, such as a "missing character" glyph (cf. 15.2, point 5).

• Note: Backslash escapes are always considered to be part of an identifier or a string (i.e., "\7B" is not punctuation, even though "{" is, and "\32" is allowed at the start of a class name, even though "2" is not).
  The identifier "te\st" is exactly the same identifier as "test".

Comprehensive list: Unicode Character 'DOWNWARDS ARROW' (U+2193).

Likely quite simple but best way is to edit manually the file .classpath at the root of your project folder with something like

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
        <attributes>
            <attribute name="maven.pomderived" value="true"/>
            <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
        </attributes>
    </classpathentry>

when you want to have jar in your WEB-IN/lib folder (case for a web app)

Looks pretty complete for a smiple survey. Don't forget to add a table for 'open values', where a customer can provide his opinion via a textbox. Link that table with a foreign key to your answer and place indexes on all your relational columns for performance.

when i run

from c in Customers
where c.CustomerID == 1
where c.CustomerID == 2
where c.CustomerID == 3
select c

and

from c in Customers
where c.CustomerID == 1 &&
c.CustomerID == 2 &&
c.CustomerID == 3
select c customer table in linqpad

against my Customer table it output the same sql query

-- Region Parameters
DECLARE @p0 Int = 1
DECLARE @p1 Int = 2
DECLARE @p2 Int = 3
-- EndRegion
SELECT [t0].[CustomerID], [t0].[CustomerName]
FROM [Customers] AS [t0]
WHERE ([t0].[CustomerID] = @p0) AND ([t0].[CustomerID] = @p1) AND ([t0].[CustomerID] = @p2)

so in translation to sql there is no difference and you already have seen in other answers how they will be converted to lambda expressions
