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.

You also seem to have a lack of understanding about how to use layout managers.
Take the time to read through Creating a GUI with Swing and Laying components out in a container
After adding JTextArea into JScrollPane here:
scroll = new JScrollPane(display);
You don't need to add it again into other container like you do:
middlePanel.add(display);
Just remove that last line of code and it will work fine. Like this:
middlePanel=new JPanel();
middlePanel.setBorder(new TitledBorder(new EtchedBorder(), "Display Area"));
// create the middle panel components
display = new JTextArea(16, 58);
display.setEditable(false); // set textArea non-editable
scroll = new JScrollPane(display);
scroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS);
//Add Textarea in to middle panel
middlePanel.add(scroll);
JScrollPane is just another container that places scrollbars around your component when its needed and also has its own layout. All you need to do when you want to wrap anything into a scroll just pass it into JScrollPane constructor:
new JScrollPane( myComponent )
or set view like this:
JScrollPane pane = new JScrollPane ();
pane.getViewport ().setView ( myComponent );
Additional:
Here is fully working example since you still did not get it working:
public static void main ( String[] args )
{
JPanel middlePanel = new JPanel ();
middlePanel.setBorder ( new TitledBorder ( new EtchedBorder (), "Display Area" ) );
// create the middle panel components
JTextArea display = new JTextArea ( 16, 58 );
display.setEditable ( false ); // set textArea non-editable
JScrollPane scroll = new JScrollPane ( display );
scroll.setVerticalScrollBarPolicy ( ScrollPaneConstants.VERTICAL_SCROLLBAR_ALWAYS );
//Add Textarea in to middle panel
middlePanel.add ( scroll );
// My code
JFrame frame = new JFrame ();
frame.add ( middlePanel );
frame.pack ();
frame.setLocationRelativeTo ( null );
frame.setVisible ( true );
}
And here is what you get:
Changing a variable doesn't magically execute code within the if
-block. Place the common code in a function, then bind the event, and call the function:
$(document).ready(function() {
// Optimalisation: Store the references outside the event handler:
var $window = $(window);
var $pane = $('#pane1');
function checkWidth() {
var windowsize = $window.width();
if (windowsize > 440) {
//if the window is greater than 440px wide then turn on jScrollPane..
$pane.jScrollPane({
scrollbarWidth:15,
scrollbarMargin:52
});
}
}
// Execute on load
checkWidth();
// Bind event listener
$(window).resize(checkWidth);
});
You don't need two JScrollPanes
.
Example:
JTextArea ta = new JTextArea();
JScrollPane sp = new JScrollPane(ta);
// Add the scroll pane into the content pane
JFrame f = new JFrame();
f.getContentPane().add(sp);
I´m not sure as to what the second problem is (based on your edit), but if you apply width:inherit
to all inner divs, it works: http://jsfiddle.net/4bGqF/9/
You might want to look into a javascript solution for browsers that you need to support and that don´t support width:inherit
From the javadoc:
The serialization runtime associates with each serializable class a version number, called a
serialVersionUID
, which is used during deserialization to verify that the sender and receiver of a serialized object have loaded classes for that object that are compatible with respect to serialization. If the receiver has loaded a class for the object that has a differentserialVersionUID
than that of the corresponding sender's class, then deserialization will result in anInvalidClassException
. A serializable class can declare its ownserialVersionUID
explicitly by declaring a field named"serialVersionUID"
that must be static, final, and of type long:
You can configure your IDE to:
As per your additional question "Can it be that the discussed warning message is a reason why my GUI application freeze?":
No, it can't be. It can cause a problem only if you are serializing objects and deserializing them in a different place (or time) where (when) the class has changed, and it will not result in freezing, but in InvalidClassException
.
This code is worked for me without setAutoResizeModes.
TableColumnModel columnModel = jTable1.getColumnModel();
columnModel.getColumn(1).setPreferredWidth(170);
columnModel.getColumn(1).setMaxWidth(170);
columnModel.getColumn(2).setPreferredWidth(150);
columnModel.getColumn(2).setMaxWidth(150);
columnModel.getColumn(3).setPreferredWidth(40);
columnModel.getColumn(3).setMaxWidth(40);
I think you'll have to import the project via the file->import wizard:
http://www.coderanch.com/t/419556/vc/Open-existing-project-Eclipse
It's not the last step, but it will start you on your way.
I also feel your pain - there is really no excuse for making it so difficult to do a simple thing like opening an existing project. I truly hope that the Eclipse designers focus on making the IDE simpler to use (tho I applaud their efforts at trying different approaches - but please, Eclipse designers, if you are listening, never complicate something simple).
You can change the value of a bool all you want. As for an if:
if randombool == True:
works, but you can also use:
if randombool:
If you want to test whether something is false you can use:
if randombool == False
but you can also use:
if not randombool:
For most cases (long for floats, long long for double and long double):
long a{ std::lround(1.5f) }; //2l
long long b{ std::llround(std::floor(1.5)) }; //1ll
It works for me:
HTML LINK to Anchor:
<a href="#security">SECURITY</a>
HTML Anchor:

position: absolute;
}
Unfortunately std::map::operator[]
is a non-const member function, and you have a const reference.
You either need to change the signature of function
or do:
MAP::const_iterator pos = map.find("string");
if (pos == map.end()) {
//handle the error
} else {
std::string value = pos->second;
...
}
operator[]
handles the error by adding a default-constructed value to the map and returning a reference to it. This is no use when all you have is a const reference, so you will need to do something different.
You could ignore the possibility and write string value = map.find("string")->second;
, if your program logic somehow guarantees that "string"
is already a key. The obvious problem is that if you're wrong then you get undefined behavior.
You have to add max-height
property.
.ScrollStyle_x000D_
{_x000D_
max-height: 150px;_x000D_
overflow-y: scroll;_x000D_
}

First, you need to configure your computer to get a static IP from your router. Instructions for how to do this can be found: here
For example, let's say you picked the IP address 192.168.1.102. After the above step is completed, you should be able to get to the website on your local machine by going to both http://localhost and http://192.168.1.102, since your computer will now always have that IP address on your network.
If you look up your IP address (such as http://www.ip-adress.com/), the IP you see is actually the IP of your router. When your friend accesses your website, you'll give him this IP. However, you need to tell your router that when it gets a request for a webpage, forward that request to your server. This is done through port forwarding.
Two examples of how to do this can be found here and here, although the exact screens you see will vary depending on the manufacturer of your router (Google for exact instructions, if needed).
For the Linksys router I have, I enter http://192.168.1.1/, enter my username/password, Applications & Gaming tab > Port Range Forward. Enter the application name (whatever you want to call it), start port (80), end port (80), protocol (TCP), ip address (using the above example, you would enter 192.168.1.102, which is the static IP you assigned your server), and be sure to check to enable the forwarding. Restart your router and the changes should take effect.
Having done all that, your friend should now be able to access your webpage by going to his web browser on his machine and entering http://IP.address.of.your.computer (the same one you see when you go here ).
As mentioned earlier, the IP address assigned to you by your ISP will eventually change whether you sign offline or not. I strongly recommend using DynDns, which is absolutely free. You can choose a hostname at their domain (such as cuga.kicks-ass.net) and your friend can then always access your website by simply going to http://cuga.kicks-ass.net in his browser. Here is their site again: DynDns
I hope this helps.
Append the following line to the end of your .vimrc
to prevent highlighting altogether:
set nohlsearch
There is a method addAll() which will serve the purpose of copying One ArrayList to another.
For example you have two Array Lists: sourceList and targetList, use below code.
targetList.addAll(sourceList);
line=$((${RANDOM} % $(wc -l < /etc/passwd)))
sed -n "${line}p" /etc/passwd
just with your file instead.
In this example I used the file /etc/password, using the special variable ${RANDOM}
(about which I learned here), and the sed
expression you had, only difference is that I am using double quotes instead of single to allow the variable expansion.
See the docs:
Since PHP 5.3, it is possible to leave out the middle part of the ternary operator. Expression
expr1 ?: expr3
returnsexpr1
ifexpr1
evaluates toTRUE
, andexpr3
otherwise.
Just summarising @libing's answer with a sample that worked for me.
val gson = Gson()
val todoItem: TodoItem = gson.fromJson(this.assets.readAssetsFile("versus.json"), TodoItem::class.java)
private fun AssetManager.readAssetsFile(fileName : String): String = open(fileName).bufferedReader().use{it.readText()}
Without this extension function the same can be achieved by using BufferedReader
and InputStreamReader
this way:
val i: InputStream = this.assets.open("versus.json")
val br = BufferedReader(InputStreamReader(i))
val todoItem: TodoItem = gson.fromJson(br, TodoItem::class.java)
This is because in relational database terminology, what you want to do is not called "inserting", but "UPDATING" - you are updating an existing row's field from one value (NULL in your case) to "test"
UPDATE your_table SET table_column = "test"
WHERE table_column = NULL
You don't need the second line if you want to update 100% of rows.
When you add an object to $stateProvider.state
that object is then passed with the state. So you can add additional properties which you can read later on when needed.
Example route configuration
$stateProvider
.state('public', {
abstract: true,
module: 'public'
})
.state('public.login', {
url: '/login',
module: 'public'
})
.state('tool', {
abstract: true,
module: 'private'
})
.state('tool.suggestions', {
url: '/suggestions',
module: 'private'
});
The $stateChangeStart
event gives you acces to the toState
and fromState
objects. These state objects will contain the configuration properties.
Example check for the custom module property
$rootScope.$on('$stateChangeStart', function(e, toState, toParams, fromState, fromParams) {
if (toState.module === 'private' && !$cookies.Session) {
// If logged out and transitioning to a logged in page:
e.preventDefault();
$state.go('public.login');
} else if (toState.module === 'public' && $cookies.Session) {
// If logged in and transitioning to a logged out page:
e.preventDefault();
$state.go('tool.suggestions');
};
});
I didn't change the logic of the cookies because I think that is out of scope for your question.
You can create a Helper to get you this to work more modular.
Value publicStates
myApp.value('publicStates', function(){
return {
module: 'public',
routes: [{
name: 'login',
config: {
url: '/login'
}
}]
};
});
Value privateStates
myApp.value('privateStates', function(){
return {
module: 'private',
routes: [{
name: 'suggestions',
config: {
url: '/suggestions'
}
}]
};
});
The Helper
myApp.provider('stateshelperConfig', function () {
this.config = {
// These are the properties we need to set
// $stateProvider: undefined
process: function (stateConfigs){
var module = stateConfigs.module;
$stateProvider = this.$stateProvider;
$stateProvider.state(module, {
abstract: true,
module: module
});
angular.forEach(stateConfigs, function (route){
route.config.module = module;
$stateProvider.state(module + route.name, route.config);
});
}
};
this.$get = function () {
return {
config: this.config
};
};
});
Now you can use the helper to add the state configuration to your state configuration.
myApp.config(['$stateProvider', '$urlRouterProvider',
'stateshelperConfigProvider', 'publicStates', 'privateStates',
function ($stateProvider, $urlRouterProvider, helper, publicStates, privateStates) {
helper.config.$stateProvider = $stateProvider;
helper.process(publicStates);
helper.process(privateStates);
}]);
This way you can abstract the repeated code, and come up with a more modular solution.
Note: the code above isn't tested
Create Arraylist<Date>
of Date class. And use Collections.sort()
for ascending order.
Sorts the specified list into ascending order, according to the natural ordering of its elements.
For Sort it in descending order See Collections.reverseOrder()
Collections.sort(yourList, Collections.reverseOrder());

I know this post is really old, but I have to reply because although BalusC's answer is marked as correct, it's not completely correct.
You have to write the query adding "[]" to foo like this:
foo[]=val1&foo[]=val2&foo[]=val3
Yes you understood it correctly, the function password_hash() will generate a salt on its own, and includes it in the resulting hash-value. Storing the salt in the database is absolutely correct, it does its job even if known.
// Hash a new password for storing in the database.
// The function automatically generates a cryptographically safe salt.
$hashToStoreInDb = password_hash($_POST['password'], PASSWORD_DEFAULT);
// Check if the hash of the entered login password, matches the stored hash.
// The salt and the cost factor will be extracted from $existingHashFromDb.
$isPasswordCorrect = password_verify($_POST['password'], $existingHashFromDb);
The second salt you mentioned (the one stored in a file), is actually a pepper or a server side key. If you add it before hashing (like the salt), then you add a pepper. There is a better way though, you could first calculate the hash, and afterwards encrypt (two-way) the hash with a server-side key. This gives you the possibility to change the key when necessary.
In contrast to the salt, this key should be kept secret. People often mix it up and try to hide the salt, but it is better to let the salt do its job and add the secret with a key.
You can use SET ECHO ON
in the beginning of your script to achieve that, however, you have to specify your script using @
instead of <
(also had to add EXIT
at the end):
test.sql
SET ECHO ON
SELECT COUNT(1) FROM dual;
SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual);
EXIT
terminal
sqlplus hr/oracle@orcl @/tmp/test.sql > /tmp/test.log
test.log
SQL> SQL> SELECT COUNT(1) FROM dual; COUNT(1) ---------- 1 SQL> SQL> SELECT COUNT(1) FROM (SELECT 1 FROM dual UNION SELECT 2 FROM dual); COUNT(1) ---------- 2 SQL> SQL> EXIT
Factory Method patter: BeanFactory for creating instance of an object Singleton : instance type can be singleton for a context Prototype : instance type can be prototype. Builder pattern: you can also define a method in a class who will be responsible for creating complex instance.
I think thats correct. RTSP may use RTP internally.
Doing an if exists ... else ... involves doing two requests minimum (one to check, one to take action). The following approach requires only one where the record exists, two if an insert is required:
DECLARE @RowExists bit
SET @RowExists = 0
UPDATE MyTable SET DataField1 = 'xxx', @RowExists = 1 WHERE Key = 123
IF @RowExists = 0
INSERT INTO MyTable (Key, DataField1) VALUES (123, 'xxx')
Did you consider using Apache Commons Net ? Since 3.3, just one jar (and you can depend on it using gradle or maven) and you're done : http://blog.dahanne.net/2013/06/17/sending-a-mail-in-java-and-android-with-apache-commons-net/
You could try changing the: SizeMode property of the PictureBox.
You could also set your image as the BackGroundImage of the PictureBox and try changing the BackGroundImageLayout to the correct mode.
For me, I had typed image with a lower case "i" instead of Image. So I did:
from PIL import Image
NOT from PIL import image
Brad Oyler's answer is correct. But you will only receive one event. If you need to get constant updates of the scroll position, you should set the scrollEventThrottle
prop, like so:
<ScrollView onScroll={this.handleScroll} scrollEventThrottle={16} >
<Text>
Be like water my friend …
</Text>
</ScrollView>
And the event handler:
handleScroll: function(event: Object) {
console.log(event.nativeEvent.contentOffset.y);
},
Be aware that you might run into performance issues. Adjust the throttle accordingly. 16 gives you the most updates. 0 only one.

In my case, I was uploading the wrong apk, to another app's release.
export PATH=/usr/pgsql-9.2/bin:$PATH
The program executable psql
is in the directory /usr/pgsql-9.2/bin
, and that directory is not included in the path by default, so we have to tell our shell (terminal) program where to find psql
. When most packages are installed, they are added to an existing path, such as /usr/local/bin
, but not this program.
So we have to add the program's path to the shell PATH variable if we do not want to have to type the complete path to the program every time we execute it.
This line should typically be added to theshell startup script, which for the bash shell will be in the file ~/.bashrc
.
Size of all tables:
Suppose your database or TABLE_SCHEMA
name is "news_alert". Then this query will show the size of all tables in the database.
SELECT
TABLE_NAME AS `Table`,
ROUND(((DATA_LENGTH + INDEX_LENGTH) / 1024 / 1024),2) AS `Size (MB)`
FROM
information_schema.TABLES
WHERE
TABLE_SCHEMA = "news_alert"
ORDER BY
(DATA_LENGTH + INDEX_LENGTH)
DESC;
Output:
+---------+-----------+
| Table | Size (MB) |
+---------+-----------+
| news | 0.08 |
| keyword | 0.02 |
+---------+-----------+
2 rows in set (0.00 sec)
For the specific table:
Suppose your TABLE_NAME
is "news". Then SQL query will be-
SELECT
TABLE_NAME AS `Table`,
ROUND(((DATA_LENGTH + INDEX_LENGTH) / 1024 / 1024),2) AS `Size (MB)`
FROM
information_schema.TABLES
WHERE
TABLE_SCHEMA = "news_alert"
AND

Adding table alias in front Set field causes this problem in my case.
Right Update Table1 Set SomeField = t2.SomeFieldValue From Table1 t1 Inner Join Table2 as t2 On t1.ID = t2.ID
Wrong Update Table1 Set t1.SomeField = t2.SomeFieldValue From Table1 t1 Inner Join Table2 as t2 On t1.ID = t2.ID
The reason for the error is that the nextInt only pulls the integer, not the newline. If you add a in.nextLine() before your for loop, it will eat the empty new line and allow you to enter 3 names.
int nnames;
String names[];
System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();
names = new String[nnames];
in.nextLine();
for (int i = 0; i < names.length; i++){
System.out.print("Type a name: ");
names[i] = in.nextLine();
}
or just read the line and parse the value as an Integer.
int nnames;
String names[];
System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = Integer.parseInt(in.nextLine().trim());
names = new String[nnames];
for (int i = 0; i < names.length; i++){
System.out.print("Type a name: ");
names[i] = in.nextLine();
}
I'm think this has been answered before...but anyway, if you want to encrypt/decrypt data, you can't use SHA256
//Key
$key = 'SuperSecretKey';
//To Encrypt:
$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, 'I want to encrypt this', MCRYPT_MODE_ECB);
//To Decrypt:
$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $encrypted, MCRYPT_MODE_ECB);
You can only include a script file in an HTML page, not in another script file. That said, you can write JavaScript which loads your "included" script into the same page:
var imported = document.createElement('script');
imported.src = '/path/to/imported/script';
document.head.appendChild(imported);
There's a good chance your code depends on your "included" script, however, in which case it may fail because the browser will load the "imported" script asynchronously. Your best bet will be to simply use a third-party library like jQuery or YUI, which solves this problem for you.
// jQuery
$.getScript('/path/to/imported/script.js', function()
{
// script is now loaded and executed.
// put your dependent JS here.
});
if addition please, if you have a long text please you can use this css code bellow;
text-overflow: ellipsis;
overflow: visible;
white-space: nowrap;
make the whole line text visible.

No. The HTML 5 spec mentions:
The method and formmethod content attributes are enumerated attributes with the following keywords and states:
The keyword get, mapping to the state GET, indicating the HTTP GET method. The GET method should only request and retrieve data and should have no other effect.
The keyword post, mapping to the state POST, indicating the HTTP POST method. The POST method requests that the server accept the submitted form's data to be processed, which may result in an item being added to a database, the creation of a new web page resource, the updating of the existing page, or all of the mentioned outcomes.
The keyword dialog, mapping to the state dialog, indicating that submitting the form is intended to close the dialog box in which the form finds itself, if any, and otherwise not submit.
The invalid value default for these attributes is the GET state
I.e. HTML forms only support GET and POST as HTTP request methods. A workaround for this is to tunnel other methods through POST by using a hidden form field which is read by the server and the request dispatched accordingly.
However, GET, POST, PUT and DELETE are supported by the implementations of XMLHttpRequest (i.e. AJAX calls) in all the major web browsers (IE, Firefox, Safari, Chrome, Opera).
Try with auto increment:
CREATE TABLE IF NOT EXISTS `my_table` (
`number` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(50) NOT NULL,
`money` int(11) NOT NULL,
PRIMARY KEY (`number`,`name`)
) ENGINE=MyISAM;
You can use Newtonsoft.Json
, it's a dependency of Microsoft.AspNet.Mvc.ModelBinding
which is a dependency of Microsoft.AspNet.Mvc
. So, you don't need to add a dependency in your project.json.
#using Newtonsoft.Json
....
JsonConvert.DeserializeObject(json);
Note, using a WebAPI controller you don't need to deal with JSON.
Json.NET has been removed from the ASP.NET Core 3.0 shared framework.
You can use the new JSON serializer layers on top of the high-performance Utf8JsonReader
and Utf8JsonWriter
. It deserializes objects from JSON and serializes objects to JSON. Memory allocations are kept minimal and includes support for reading and writing JSON with Stream asynchronously.
To get started, use the JsonSerializer
class in the System.Text.Json.Serialization
namespace. See the documentation for information and samples.
To use Json.NET in an ASP.NET Core 3.0 project:
services.AddMvc()
.AddNewtonsoftJson();

By combining Jason Robinson's answer with Felix's answer and filling the missing parts, here is the final complete solution for this issue that will do the following after testing it on Android Android 4.1 (Jelly Bean), Android 4.4 (KitKat) and Android 5.0 (Lollipop).
Steps
Scale down the image if it was bigger than 1024x1024.
Rotate the image to the right orientation only if it was rotate 90, 180 or 270 degree.
Recycle the rotated image for memory purposes.
Here is the code part:
Call the following method with the current Context
and the image URI
that you want to fix
/**
* This method is responsible for solving the rotation issue if exist. Also scale the images to
* 1024x1024 resolution
*
* @param context The current context
* @param selectedImage The Image URI
* @return Bitmap image results
* @throws IOException
*/
public static Bitmap handleSamplingAndRotationBitmap(Context context, Uri selectedImage)
throws IOException {
int MAX_HEIGHT = 1024;
int MAX_WIDTH = 1024;
// First decode with inJustDecodeBounds=true to check dimensions
final BitmapFactory.Options options = new BitmapFactory.Options();
options.inJustDecodeBounds = true;
InputStream imageStream = context.getContentResolver().openInputStream(selectedImage);
BitmapFactory.decodeStream(imageStream, null, options);
imageStream.close();
// Calculate inSampleSize
options.inSampleSize = calculateInSampleSize(options, MAX_WIDTH, MAX_HEIGHT);
// Decode bitmap with inSampleSize set
options.inJustDecodeBounds = false;
imageStream = context.getContentResolver().openInputStream(selectedImage);
Bitmap img = BitmapFactory.decodeStream(imageStream, null, options);
img = rotateImageIfRequired(context, img, selectedImage);
return img;
}
Here is the CalculateInSampleSize
method from the pre mentioned source:
/**
* Calculate an inSampleSize for use in a {@link BitmapFactory.Options} object when decoding
* bitmaps using the decode* methods from {@link BitmapFactory}. This implementation calculates
* the closest inSampleSize that will result in the final decoded bitmap having a width and
* height equal to or larger than the requested width and height. This implementation does not
* ensure a power of 2 is returned for inSampleSize which can be faster when decoding but
* results in a larger bitmap which isn't as useful for caching purposes.
*
* @param options An options object with out* params already populated (run through a decode*
* method with inJustDecodeBounds==true
* @param reqWidth The requested width of the resulting bitmap
* @param reqHeight The requested height of the resulting bitmap
* @return The value to be used for inSampleSize
*/
private static int calculateInSampleSize(BitmapFactory.Options options,
int reqWidth, int reqHeight) {
// Raw height and width of image
final int height = options.outHeight;
final int width = options.outWidth;
int inSampleSize = 1;
if (height > reqHeight || width > reqWidth) {
// Calculate ratios of height and width to requested height and width
final int heightRatio = Math.round((float) height / (float) reqHeight);
final int widthRatio = Math.round((float) width / (float) reqWidth);
// Choose the smallest ratio as inSampleSize value, this will guarantee a final image
// with both dimensions larger than or equal to the requested height and width.
inSampleSize = heightRatio < widthRatio ? heightRatio : widthRatio;
// This offers some additional logic in case the image has a strange
// aspect ratio. For example, a panorama may have a much larger
// width than height. In these cases the total pixels might still
// end up being too large to fit comfortably in memory, so we should
// be more aggressive with sample down the image (=larger inSampleSize).
final float totalPixels = width * height;
// Anything more than 2x the requested pixels we'll sample down further
final float totalReqPixelsCap = reqWidth * reqHeight * 2;
while (totalPixels / (inSampleSize * inSampleSize) > totalReqPixelsCap) {
inSampleSize++;
}
}
return inSampleSize;
}
Then comes the method that will check the current image orientation to decide the rotation angle
/**
* Rotate an image if required.
*
* @param img The image bitmap
* @param selectedImage Image URI
* @return The resulted Bitmap after manipulation
*/
private static Bitmap rotateImageIfRequired(Context context, Bitmap img, Uri selectedImage) throws IOException {
InputStream input = context.getContentResolver().openInputStream(selectedImage);
ExifInterface ei;
if (Build.VERSION.SDK_INT > 23)
ei = new ExifInterface(input);
else
ei = new ExifInterface(selectedImage.getPath());
int orientation = ei.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
switch (orientation) {
case ExifInterface.ORIENTATION_ROTATE_90:
return rotateImage(img, 90);
case ExifInterface.ORIENTATION_ROTATE_180:
return rotateImage(img, 180);
case ExifInterface.ORIENTATION_ROTATE_270:
return rotateImage(img, 270);
default:
return img;
}
}
Finally the rotation method itself
private static Bitmap rotateImage(Bitmap img, int degree) {
Matrix matrix = new Matrix();
matrix.postRotate(degree);
Bitmap rotatedImg = Bitmap.createBitmap(img, 0, 0, img.getWidth(), img.getHeight(), matrix, true);
img.recycle();
return rotatedImg;
}

I have spent two solid days working on this so I just thought I'd share my solution as well. As of 26/11/10 the current branch is 1.2.X so that means you'll have to have the following in you settings.py:
MEDIA_ROOT = "<path_to_files>" (i.e. /home/project/django/app/templates/static)
MEDIA_URL = "http://localhost:8000/static/"
*(remember that MEDIA_ROOT is where the files are and MEDIA_URL is a constant that you use in your templates.)*
Then in you url.py place the following:
import settings
# stuff
(r'^static/(?P<path>.*)$', 'django.views.static.serve',{'document_root': settings.MEDIA_ROOT}),
Then in your html you can use:
<img src="{{ MEDIA_URL }}foo.jpg">
The way django works (as far as I can figure is:
I know this is quite out of date, but this might still be useful for those coming late to the party. (EDIT: updated since this still gets traffic and @Goozak has pointed out in the comments that my original analysis of the sample was incorrect as well.)
I pulled this from the example code in your link:
IF !%1==! GOTO VIEWDATA
REM IF NO COMMAND-LINE ARG...
FIND "%1" C:\BOZO\BOOKLIST.TXT
GOTO EXIT0
REM PRINT LINE WITH STRING MATCH, THEN EXIT.
:VIEWDATA
TYPE C:\BOZO\BOOKLIST.TXT | MORE
REM SHOW ENTIRE FILE, 1 PAGE AT A TIME.
:EXIT0
!%1==!
is simply an idiomatic use of ==
intended to verify that the thing on the left, that contains your variable, is different from the thing on the right, that does not. The !
in this case is just a character placeholder. It could be anything. If %1
has content, then the equality will be false, if it does not you'll just be comparing !
to !
and it will be true.
!==!
is not an operator, so writing "asdf" !==! "fdas"
is pretty nonsensical.
The suggestion to use if not "asdf" == "fdas"
is definitely the way to go.
I think you've actually got a wider confusion here.
The initial error is that you're trying to call split
on the whole list of lines, and you can't split
a list of strings, only a string. So, you need to split
each line, not the whole thing.
And then you're doing for points in Type
, and expecting each such points
to give you a new x
and y
. But that isn't going to happen. Types
is just two values, x
and y
, so first points
will be x
, and then points will be y
, and then you'll be done. So, again, you need to loop over each line and get the x
and y
values from each line, not loop over a single Types
from a single line.
So, everything has to go inside a loop over every line in the file, and do the split
into x
and y
once for each line. Like this:
def getQuakeData():
filename = input("Please enter the quake file: ")
readfile = open(filename, "r")
for line in readfile:
Type = line.split(",")
x = Type[1]
y = Type[2]
print(x,y)
getQuakeData()
As a side note, you really should close
the file, ideally with a with
statement, but I'll get to that at the end.
Interestingly, the problem here isn't that you're being too much of a newbie, but that you're trying to solve the problem in the same abstract way an expert would, and just don't know the details yet. This is completely doable; you just have to be explicit about mapping the functionality, rather than just doing it implicitly. Something like this:
def getQuakeData():
filename = input("Please enter the quake file: ")
readfile = open(filename, "r")
readlines = readfile.readlines()
Types = [line.split(",") for line in readlines]
xs = [Type[1] for Type in Types]
ys = [Type[2] for Type in Types]
for x, y in zip(xs, ys):
print(x,y)
getQuakeData()
Or, a better way to write that might be:
def getQuakeData():
filename = input("Please enter the quake file: ")
# Use with to make sure the file gets closed
with open(filename, "r") as readfile:
# no need for readlines; the file is already an iterable of lines
# also, using generator expressions means no extra copies
types = (line.split(",") for line in readfile)
# iterate tuples, instead of two separate iterables, so no need for zip
xys = ((type[1], type[2]) for type in types)
for x, y in xys:
print(x,y)
getQuakeData()
Finally, you may want to take a look at NumPy and Pandas, libraries which do give you a way to implicitly map functionality over a whole array or frame of data almost the same way you were trying to.
If you already have a map and would like to sort it on keys, simply use :
Map<String, String> treeMap = new TreeMap<String, String>(yourMap);
A complete working example :
import java.util.HashMap;
import java.util.Set;
import java.util.Map;
import java.util.TreeMap;
import java.util.Iterator;
class SortOnKey {
public static void main(String[] args) {
HashMap<String,String> hm = new HashMap<String,String>();
hm.put("3","three");
hm.put("1","one");
hm.put("4","four");
hm.put("2","two");
printMap(hm);
Map<String, String> treeMap = new TreeMap<String, String>(hm);
printMap(treeMap);
}//main
public static void printMap(Map<String,String> map) {
Set s = map.entrySet();
Iterator it = s.iterator();
while ( it.hasNext() ) {
Map.Entry entry = (Map.Entry) it.next();
String key = (String) entry.getKey();
String value = (String) entry.getValue();
System.out.println(key + " => " + value);
}//while
System.out.println("========================");
}//printMap
}//class
This simple way to do your task:
setContentView(R.id.main);
ImageView iv = (ImageView) findViewById(R.id.left);
int width = 60;
int height = 60;
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(width,height);
iv.setLayoutParams(parms);
and another way if you want to give screen size in height and width then use below code :
setContentView(R.id.main);
Display display = getWindowManager().getDefaultDisplay();
ImageView iv = (LinearLayout) findViewById(R.id.left);
int width = display.getWidth(); // ((display.getWidth()*20)/100)
int height = display.getHeight();// ((display.getHeight()*30)/100)
LinearLayout.LayoutParams parms = new LinearLayout.LayoutParams(width,height);
iv.setLayoutParams(parms);
hope use full to you.
The easiest way is to use the request module.
request('https://example.com/url?a=b', function (error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
});
I am facing problems with composer because it consumes all the available memory, and then, the process get killed ( actualy, the output message is "Killed")
So, I was looking for a solution to limit composer memory usage.
I tried ( from @Sven answers )
$ php -d memory_limit=512M /usr/local/bin/composer update
But it didn't work because
"Composer internally increases the memory_limit to 1.5G."
-> Thats from composer oficial website.
Then I found a command that works :
$ COMPOSER_MEMORY_LIMIT=512M php composer.phar update
Althought, in my case 512mb is not enough !

I'd say @Wim is right. You should use ToString()
for logfiles - assuming a technical audience - and Message
, if at all, to display to the user. One could argue that even that is not suitable for a user, for every exception type and occurance out there (think of ArgumentExceptions, etc.).
Also, in addition to the StackTrace, ToString()
will include information you will not get otherwise. For example the output of fusion, if enabled to include log messages in exception "messages".
Some exception types even include additional information (for example from custom properties) in ToString()
, but not in the Message.
try this
= f.input :title, :as => :hidden, :input_html => { :value => "some value" }
I think Scapy is what are you looking for.

If you use git LFS, git count-objects does not count your binaries, but only the pointers to them.
If your LFS files are managed by Artifactorys, you should use the REST API:
Declare the $items
array outside the loop and use $items[]
to add items to the array:
$items = array();
foreach($group_membership as $username) {
$items[] = $username;
}
print_r($items);
We can adjust the factor levels based on target
and use it in arrange
library(dplyr)
df %>% arrange(factor(name, levels = target))
# name value
#1 b TRUE
#2 c FALSE
#3 a TRUE
#4 d FALSE
Or order
it and use it in slice
df %>% slice(order(factor(name, levels = target)))

I wanted to elaborate the answer by lifeless a bit because when I started reading about how to use super() in a multiple inheritance hierarchy in Python, I did't get it immediately.
What you need to understand is that super(MyClass, self).__init__()
provides the next __init__
method according to the used Method Resolution Ordering (MRO) algorithm in the context of the complete inheritance hierarchy.
This last part is crucial to understand. Let's consider the example again:
#!/usr/bin/env python2
class First(object):
def __init__(self):
print "First(): entering"
super(First, self).__init__()
print "First(): exiting"
class Second(object):
def __init__(self):
print "Second(): entering"
super(Second, self).__init__()
print "Second(): exiting"
class Third(First, Second):
def __init__(self):
print "Third(): entering"
super(Third, self).__init__()
print "Third(): exiting"
According to this article about Method Resolution Order by Guido van Rossum, the order to resolve __init__
is calculated (before Python 2.3) using a "depth-first left-to-right traversal" :
Third --> First --> object --> Second --> object
After removing all duplicates, except for the last one, we get :
Third --> First --> Second --> object
So, lets follow what happens when we instantiate an instance of the Third
class, e.g. x = Third()
.
Third.__init__
executes.
Third(): entering
super(Third, self).__init__()
executes and MRO returns First.__init__
which is called.First.__init__
executes.
First(): entering
super(First, self).__init__()
executes and MRO returns Second.__init__
which is called.Second.__init__
executes.
Second(): entering
super(Second, self).__init__()
executes and MRO returns object.__init__
which is called.object.__init__
executes (no print statements in the code there)Second.__init__
which then prints Second(): exiting
First.__init__
which then prints First(): exiting
Third.__init__
which then prints Third(): exiting
This details out why instantiating Third() results in to :
Third(): entering
First(): entering
Second(): entering
Second(): exiting
First(): exiting
Third(): exiting
The MRO algorithm has been improved from Python 2.3 onwards to work well in complex cases, but I guess that using the "depth-first left-to-right traversal" + "removing duplicates expect for the last" still works in most cases (please comment if this is not the case). Be sure to read the blog post by Guido!

sp.ShowDialog();
In my case, I get two objects in and I don't know if it's date or timedate objects. Converting to date won't be good as I'd be dropping information - two timedate objects with the same date should be sorted correctly. I'm OK with the dates being sorted before the datetime with same date.
I think I will use strftime before comparing:
>>> foo=datetime.date(2015,1,10)
>>> bar=datetime.datetime(2015,2,11,15,00)
>>> foo.strftime('%F%H%M%S') > bar.strftime('%F%H%M%S')
False
>>> foo.strftime('%F%H%M%S') < bar.strftime('%F%H%M%S')
True
Not elegant, but should work out. I think it would be better if Python wouldn't raise the error, I see no reasons why a datetime shouldn't be comparable with a date. This behaviour is consistent in python2 and python3.
Use IS NULL

A little clearer... A software program that has kernel mode access has total access to all of the computer's data and its hardware.
Since Windows Vista Microsoft has stopped any and all I/O processes from accessing the kernel (ring 0) directly ever again. The closest we get is a folder created as a virtual kernel access partition, but technically no access to kernel itself; the kernel meets halfway.
This is because the software itself dictates which token to use, so if it asks for an administrator access token, instead of just allowing communications with the kernel like on Windows XP you are prompted to allow access to the kernel, each and every time. Changing UAC could reduce prompts, but never the kernel prompts.
Even when you login as an Administrator, you are running processes as a standard user until prompted to elevate the rights you have. I believe logged in as the administrator saves you from entering the credentials. But it also writes to the administrator users folder structure.
Kernel access is similar to root access in Linux. When you elevate your permissions you are isolating yourself from the root of C:\ and whatever lovely environment variables are contained within.
If you remember BSODs this was the OS shutting down when it believed a bad I/O reached the kernel.
Use Socket.Connected
Property.
--UPDATE--
As Paul Turner answered Socket.Connected cannot be used in this situation. You need to poll connection every time to see if connection is still active. See 2
Your server tells you exactly what you need : [Hint: SSLProxyEngine]
You need to add that directive to your VirtualHost

ProxyPassReverse /primary/store https://localhost:9763/store/
var c = {'a':'A', 'b':'B', 'c':'C'};

for (var i in c) {
if (c.hasOwnProperty(i)) count++;
}
alert(count);
Take a look at the JavaDoc for RestTemplate.
There is the corresponding getForObject
methods that are the HTTP GET equivalents of postForObject
, but they doesn't appear to fulfil your requirements of "GET with headers", as there is no way to specify headers on any of the calls.
Looking at the JavaDoc, no method that is HTTP GET specific allows you to also provide header information. There are alternatives though, one of which you have found and are using. The exchange
methods allow you to provide an HttpEntity
object representing the details of the request (including headers). The execute
methods allow you to specify a RequestCallback
from which you can add the headers upon its invocation.
I enabled the Failed Request Tracing, and got the following info:
<EventData>
<Data Name="ContextId">{00000000-0000-0000-0F00-0080000000FA}</Data>
<Data Name="ModuleName">WebDAVModule</Data>

<Data Name="HttpReason">Method Not Allowed</Data>
<Data Name="HttpSubStatus">0</Data>
<Data Name="ErrorCode">0</Data>

</EventData>
So, I uninstalled the WebDAVModule from my IIS, everything is fine now~
The IIS tracing feature is very helpful.

The easiest way is to put the HTML inside of single quotes. And the modified json object is as follows:
[
{
"id": "services.html",
"img": "img/SolutionInnerbananer.jpg",
"html": '<h2 class="fg-white">AboutUs</h2><p class="fg-white">developing and supporting complex IT solutions.Touchingmillions of lives world wide by bringing in innovative technology </p>'
}
];
And the best way is to esacape the double quotes and other characters that need to be escaped. The modified json object is as follows:
[
{
"id": "services.html",
"img": "img/SolutionInnerbananer.jpg",
"html": "<h2 class=\"fg-white\">AboutUs</h2><p class=\"fg-white\">developing and supporting complex IT solutions.Touchingmillions of lives world wide by bringing in innovative technology </p>"
}
];
Try this:
String result = "34.1 -118.33\n<!--ABCDEFG-->";
result = result.substring(0, result.indexOf("\n"));
This problem also occurs if a 'view' (imaginary table) exists in database as same name as our new table name.
(Not exactly an answer for you, since do you want avoid opening the files, but maybe this helps others).

plt.subplots()
is a function that returns a tuple containing a figure and axes object(s). Thus when using fig, ax = plt.subplots()
you unpack this tuple into the variables fig
and ax
. Having fig
is useful if you want to change figure-level attributes or save the figure as an image file later (e.g. with fig.savefig('yourfilename.png')
). You certainly don't have to use the returned figure object but many people do use it later so it's common to see. Also, all axes objects (the objects that have plotting methods), have a parent figure object anyway, thus:
fig, ax = plt.subplots()
is more concise than this:
fig = plt.figure()
ax = fig.add_subplot(111)

If using xib
s, a very easy implementation is to encapsulate all subviews inside a container view with resizing flags (which you'll already be using for 3.5" and 4" compatibility) so that the view hierarchy looks something like this
and then in viewDidLoad
, do something like this:
- (void)viewDidLoad
{
[super viewDidLoad];
// initializations
if(SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"7.0")) // only for iOS 7 and above
{
CGRect frame = containerView.frame;
frame.origin.y += 20;
frame.size.height -= 20;
containerView.frame = frame;
}
}
This way, the nibs need not be modified for iOS 7 compatibility. If you have a background, it can be kept outside containerView
and let it cover the whole screen.
Use the not
boolean operator:
nyval = not myval
not
returns a boolean value (True
or False
):
>>> not 1
False
>>> not 0
True
If you must have an integer, cast it back:
nyval = int(not myval)
However, the python bool
type is a subclass of int
, so this may not be needed:
>>> int(not 0)
1
>>> int(not 1)
0
>>> not 0 == 1
True
>>> not 1 == 0
True
If you want to increase your heap space, you can use java -Xms<initial heap size> -Xmx<maximum heap size>
on the command line. By default, the values are based on the JRE version and system configuration. You can find out more about the VM options on the Java website.
However, I would recommend profiling your application to find out why your heap size is being eaten. NetBeans has a very good profiler included with it. I believe it uses the jvisualvm
under the hood. With a profiler, you can try to find where many objects are being created, when objects get garbage collected, and more.
For me, I was getting this error message when using PUT
or DELETE
to WebAPI. I also tried re-registering .NET Framework as suggested but to no avail.
I was able to fix this by disabling WebDAV for my individual application pool, this stopped the 'bad module' error when using PUT
or DELETE
.
WebDAV Authoring Tools
in the listDisable WebDAV
in the top right.This link is where I found the instructions but it's not very clear.
I found a way that works for me. It is not 100% exact but it eliminates all strings that contain more than just the word I am looking for because I check for the string not containing individual spaces too. By the way you don't need these " ". jQuery knows you are looking for a string. Make sure you only have one space in the :contains( ) part otherwise it won't work.
<p>hello</p>
<p>hello world</p>
$('p:contains(hello):not(:contains( ))').css('font-weight', 'bold');
And yes I know it won't work if you have stuff like <p>helloworld</p>
Question might be a little dated, but you could simply use AbstractMap.SimpleEntry<> as follows:
private Map<String, AttributeType> mapConfig(
Map<String, String> input, String prefix) {
int subLength = prefix.length();
return input.entrySet()
.stream()
.map(e -> new AbstractMap.SimpleEntry<>(
e.getKey().substring(subLength),
AttributeType.GetByName(e.getValue()))
.collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));
any other Pair-like value object would work too (ie. ApacheCommons Pair tuple).
Under certain circumstances, IE6 will still cache files even when Cache-Control: no-cache
is in the response headers.
If the no-cache directive does not specify a field-name, then a cache MUST NOT use the response to satisfy a subsequent request without successful revalidation with the origin server.
In my application, if you visited a page with the no-cache
header, then logged out and then hit back in your browser, IE6 would still grab the page from the cache (without a new/validating request to the server). Adding in the no-store
header stopped it doing so. But if you take the W3C at their word, there's actually no way to control this behavior:
History buffers MAY store such responses as part of their normal operation.
General differences between browser history and the normal HTTP caching are described in a specific sub-section of the spec.
I can't reproduce this issue in a simple .NET 4.0 console application:
static class Program
{
static void Main(string[] args)
{
var myDict = new Dictionary<string, string>
{
{ "key1", "value1" },
{ "key2", "value2" }
};
Console.ReadKey();
}
}
Can you try to reproduce it in a simple Console application and go from there? It seems likely that you're targeting .NET 2.0 (which doesn't support it) or client profile framework, rather than a version of .NET that supports initialization syntax.
We can add java folder from
It works fine.
Consider an example,
class Animal {
public void eat(String str) {
System.out.println("Eating for grass");
}
}
class Goat extends Animal {
public void eat(String str) {
System.out.println("blank");
}
}
class Another extends Goat{
public void eat(String str) {
System.out.println("another");
}
}
public class InheritanceSample {
public static void main(String[] args) {
Animal a = new Animal();
Another t5 = (Another) new Goat();
}
}
At Another t5 = (Another) new Goat()
: you will get a ClassCastException
because you cannot create an instance of the Another
class using Goat
.
Note: The conversion is valid only in cases where a class extends a parent class and the child class is casted to its parent class.
How to deal with the ClassCastException
:
So yes, you should prefer the shadowPath property for performance, but also: From the header file of CALayer.shadowPath
Specifying the path explicitly using this property will usually * improve rendering performance, as will sharing the same path * reference across multiple layers
A lesser known trick is sharing the same reference across multiple layers. Of course they have to use the same shape, but this is common with table/collection view cells.
I don't know why it gets faster if you share instances, i'm guessing it caches the rendering of the shadow and can reuse it for other instances in the view. I wonder if this is even faster with
OK, so we have to do splitting as you already got the answer I would generalize it.
If you want to split any string by spaces, delimiter(special chars).
First, remove the leading space as they create most of the issues.
str1 = " Hello I'm your String ";
str2 = " Are you serious about this question_ boy, aren't you? ";
First remove the leading space which can be space, tab etc.
String s = str1.replaceAll("^\\s+","");//starting with whitespace one or more
Now if you want to split by space or any special char.
String[] sa = s.split("[^\\w]+");//split by any non word char
But as w contains [a-zA-Z_0-9] ,so if you want to split by underscore(_) also use
String[] sa = s.split("[!,? ._'@]+");//for str2 after removing leading space
I had the same issue, I cleaned and rebuilt the project and it worked.
public static Date convertTimestampToDate(Timestamp timestamp) {
Instant ins=timestamp.toLocalDateTime().atZone(ZoneId.systemDefault()).toInstant();
return Date.from(ins);
}
Rather than resetting the locale after the installation of the locales package you can answer the questions you would normally get asked (which is disabled by noninteractive
) before installing the package so that the package scripts setup the locale correctly, this example sets the locale to english (British, UTF-8):
RUN echo locales locales/default_environment_locale select en_GB.UTF-8 | debconf-set-selections
RUN echo locales locales/locales_to_be_generated select "en_GB.UTF-8 UTF-8" | debconf-set-selections
RUN \
apt-get update && \
DEBIAN_FRONTEND=noninteractive apt-get install -y locales && \
rm -rf /var/lib/apt/lists/*
If you want it visually formatted to two decimals as a string (for output) use toFixed()
:
var priceString = someValue.toFixed(2);
The answer by @David has two problems:
It leaves the result as a floating point number, and consequently holds the possibility of displaying a particular result with many decimal places, e.g. 134.1999999999
instead of "134.20"
.
If your value is an integer or rounds to one tenth, you will not see the additional decimal value:
var n = 1.099;
(Math.round( n * 100 )/100 ).toString() //-> "1.1"
n.toFixed(2) //-> "1.10"
var n = 3;
(Math.round( n * 100 )/100 ).toString() //-> "3"
n.toFixed(2) //-> "3.00"
And, as you can see above, using toFixed()
is also far easier to type. ;)
When running the development server - which is what you get by running app.run()
, you get a single synchronous process, which means at most 1 request is being processed at a time.
By sticking Gunicorn in front of it in its default configuration and simply increasing the number of --workers
, what you get is essentially a number of processes (managed by Gunicorn) that each behave like the app.run()
development server. 4 workers == 4 concurrent requests. This is because Gunicorn uses its included sync
worker type by default.
It is important to note that Gunicorn also includes asynchronous workers, namely eventlet
and gevent
(and also tornado
, but that's best used with the Tornado framework, it seems). By specifying one of these async workers with the --worker-class
flag, what you get is Gunicorn managing a number of async processes, each of which managing its own concurrency. These processes don't use threads, but instead coroutines. Basically, within each process, still only 1 thing can be happening at a time (1 thread), but objects can be 'paused' when they are waiting on external processes to finish (think database queries or waiting on network I/O).
This means, if you're using one of Gunicorn's async workers, each worker can handle many more than a single request at a time. Just how many workers is best depends on the nature of your app, its environment, the hardware it runs on, etc. More details can be found on Gunicorn's design page and notes on how gevent works on its intro page.

There's a jQuery plugin called "imagesLoaded" that provides a cross-browser compatible method to check if an element's image(s) have been loaded.
Site: https://github.com/desandro/imagesloaded/
Usage for a container that has many images inside:
$('container').imagesLoaded(function(){
console.log("I loaded!");
})
The plugin is great:

The easiest solution is going to the config.js and setting:
config.allowedContent = true;
(Remember to clear browser's cache). Then CKEditor stops filtering the inputted content at all. However, this will totally disable content filtering which is one of the most important CKEditor features.
You can also configure CKEditor's content filter more precisely to allow only these element, classes, styles and attributes which you need. This solution is much better, because CKEditor will still remove a lot of crappy HTML which browsers produce when copying and pasting content, but it will not strip the content you want.
For example, you can extend the default CKEditor's configuration to accept all div classes:
config.extraAllowedContent = 'div(*)';
Or some Bootstrap stuff:
config.extraAllowedContent = 'div(col-md-*,container-fluid,row)';
Or you can allow description lists with optional dir
attributes for dt
and dd
elements:
config.extraAllowedContent = 'dl; dt dd[dir]';
These were just very basic examples. You can write all kind of rules - requiring attributes, classes or styles, matching only special elements, matching all elements. You can also disallow stuff and totally redefine CKEditor's rules. Read more about:

When you make a call to using namespace <some_namespace>;
all symbols in that namespace will become visible without adding the namespace prefix. A symbol may be for instance a function, class or a variable.
E.g. if you add using namespace std;
you can write just cout
instead of std::cout
when calling the operator cout
defined in the namespace std
.
This is somewhat dangerous because namespaces are meant to be used to avoid name collisions and by writing using namespace
you spare some code, but loose this advantage. A better alternative is to use just specific symbols thus making them visible without the namespace prefix. Eg:
#include <iostream>
using std::cout;
int main() {
cout << "Hello world!";
return 0;
}

You could do:
radio1.SelectedIndex = 1;
But this is the most simple form and would most likely become problematic as your UI grows. Say, for instance, if a team member inserts an item in the RadioButtonList
above option2
but doesn't know we use magic numbers in code-behind to select - now the app selects the wrong index!
Maybe you want to look into using FindControl in order to determine the ListItem
actually required, by name, and selecting appropriately. For instance:
//omitting possible null reference checks...
var wantedOption = radio1.FindControl("option2").Selected = true;
DataSet is collection of DataTables.... you can get the datatable from DataSet as below.

You can work around that via a Live Template. Go to Settings -> Live Template, click the "Add"-Button (green plus on the right).
In the "Abbreviation" field, enter the string that should activate the template (e.g. @a
), and in the "Template Text" area enter the string to complete (e.g. @author - My Name
). Set the "Applicable context" to Java (Comments only maybe) and set a key to complete (on the right).
I tested it and it works fine, however IntelliJ seems to prefer the inbuild templates, so "@a + Tab" only completes "author". Setting the completion key to Space worked however.
To change the user name that is automatically inserted via the File Templates (when creating a class for example), can be changed by adding

I had the same issue, multiple data type values in single column, package load only numeric values. Remains all it updated as null.
Solution
To fix this changing the excel data type is one of the solution. In Excel Copy the column data and paste in different file. Delete that column and insert new column as Text datatype and paste that copied data in new column.
Now in ssis package delete and recreate the Excel source and destination table change the column data type as varchar.
This will work.
Suppose consider two string s and t.
Give them some values.
When you compare them using (s==t) it returns a boolean value(true or false , 1 or 0).
But when you compare using s.compare(t) ,the expression returns a value
(i) 0 - if s and t are equal
(ii) <0 - either if the value of the first unmatched character in s is less than that of t or the length of s is less than that of t.
(iii) >0 - either if the value of the first unmatched character in t is less than that of s or the length of t is less than that of s.

The reason is the browser can not understand it and try to somehow translate it to what it can understand and in this case into a hexadecimal value!...
chucknorris
starts with c
which is recognised character in hexadecimal, also it's converting all unrecognised characters into 0
!
So chucknorris
in hexadecimal format becomes: c00c00000000
, all other characters become 0
and c
remains where they are...
Now they get divided by 3 for RGB
(red, green, blue)... R: c00c, G: 0000, B:0000
...
But we know valid hexadecimal for RGB is just 2 characters, means R: c0, G: 00, B:00

One of the above answer states to convert XML String to bytes which is not needed. Instead you can can use InputSource
and supply it with StringReader
.
String xmlStr = "<message>HELLO!</message>";
DocumentBuilder db = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(xmlStr)));
System.out.println(doc.getFirstChild().getNodeValue());
You can also use PostCSS and the custom selectors plugin
@custom-selector :--headings h1, h2, h3, h4, h5, h6;
article :--headings {
margin-top: 0;
}
Output:
article h1,
article h2,
article h3,
article h4,
article h5,
article h6 {
margin-top: 0;
}
After failed attempts to find references to EntityFramework in repositories.config and elsewhere, I stumbled upon a reference in Web.config as I was editing it to help with my diagnosis.
The bindingRedirect referenced 5.0.0.0 which was no longer installed and this appeared to be the source of the exception. Honestly, I did not add this reference to Web.config and, after trying to duplicate the error in a separate project, discovered that it is not added by the NuGet package installer so, I don't know why it was there but something added it.
<dependentAssembly>
<assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-5.0.0.0" newVersion="5.0.0.0" />
</dependentAssembly>
I decided to replace this with the equivalent element from a working project. NB the references to 5.0.0.0 are replaced with 4.3.1.0 in the following:
<dependentAssembly>
<assemblyIdentity name="EntityFramework" publicKeyToken="b77a5c561934e089" culture="neutral" />
<bindingRedirect oldVersion="0.0.0.0-4.3.1.0" newVersion="4.3.1.0" />
</dependentAssembly>
This worked!
I then decided to remove the dependentAssembly reference for the EntityFramework in its entirety.
It still worked!

After upgrading lots of packages (Spyder
3 to 4, Keras
and Tensorflow
and lots of their dependencies), I had the same problem today! I cannot figure out what happened; but the (conda-based) virtual environment that kept using Spyder
3 did not have the problem. Although installing tkinter
or changing the backend, via matplotlib.use('TkAgg)
as shown above, or this nice post on how to change the backend, might well resolve the problem, I don't see these as rigid solutions. For me, uninstalling matplotlib
and reinstalling it was magic and the problem was solved.
pip uninstall matplotlib
... then, install
pip install matplotlib
From all the above, this could be a package management problem, and BTW, I use both conda
and pip
, whenever feasible.
I don't think Bass's answer is correct. Why touch the row margins? They have a negative margin to offset the column padding for the columns on the edge of the row. Messing with this will break any nested rows.
The answer is simple, just make the container padding equal to the gutter size:
e.g for default bootstrap:
.container {
padding-left:30px;
padding-right:30px;

Omar's solution is decent* if you cannot upgrade your environment to .NET 4.5 in order to gain access to the async and await APIs. That said, there here is one important change that should be made in order to avoid poor performance. A slight delay should be added between calls to Application.DoEvents() in order to prevent excessive CPU usage. By adding
Thread.Sleep(1);
before the call to Application.DoEvents(), you can add such a delay (1 millisecond) and prevent the application from using all of the cpu cycles available to it.
private void WaitNSeconds(int seconds)
{
if (seconds < 1) return;
DateTime _desired = DateTime.Now.AddSeconds(seconds);
while (DateTime.Now < _desired) {
Thread.Sleep(1);
System.Windows.Forms.Application.DoEvents();
}
}
*See https://blog.codinghorror.com/is-doevents-evil/ for a more detailed discussion on the potential pitfalls of using Application.DoEvents().
In java System.out.println()
prints something to console. In javascript same can be achieved using console.log()
.
You need to view browser console by pressing F12
key which opens developer tool and then switch to console
tab.
var eventids = GetEventIdsByEventDate(DateTime.Now);
var result = eventsdb.Where(e => eventids.Contains(e));
If you are returnning List<EventFeed>
inside the method, you should change the method return type from IEnumerable<EventFeed>
to List<EventFeed>
.
Text decoration affects the underline, not the color.
To set the visited color to the same as the default, try:
a {
color: blue;
}
Or
a {
text-decoration: none;
}
a:link, a:visited {
color: blue;
}
a:hover {
color: red;
}
Just .filter()
it first:
var sources = images.filter(function(img) {
if (img.src.split('.').pop() === "json") {
return false; // skip
}
return true;
}).map(function(img) { return img.src; });
If you don't want to do that, which is not unreasonable since it has some cost, you can use the more general .reduce()
. You can generally express .map()
in terms of .reduce
:
someArray.map(function(element) {
return transform(element);
});
can be written as
someArray.reduce(function(result, element) {
result.push(transform(element));
return result;
}, []);
So if you need to skip elements, you can do that easily with .reduce()
:
var sources = images.reduce(function(result, img) {
if (img.src.split('.').pop() !== "json") {
result.push(img.src);
}
return result;
}, []);
In that version, the code in the .filter()
from the first sample is part of the .reduce()
callback. The image source is only pushed onto the result array in the case where the filter operation would have kept it.
update — This question gets a lot of attention, and I'd like to add the following clarifying remark. The purpose of .map()
, as a concept, is to do exactly what "map" means: transform a list of values into another list of values according to certain rules. Just as a paper map of some country would seem weird if a couple of cities were completely missing, a mapping from one list to another only really makes sense when there's a 1 to 1 set of result values.
I'm not saying that it doesn't make sense to create a new list from an old list with some values excluded. I'm just trying to make clear that .map()
has a single simple intention, which is to create a new array of the same length as an old array, only with values formed by a transformation of the old values.
You can have a Windows 10 configuration with and without Hyper-V as follows in an Admin prompt:
bcdedit /copy {current} /d "Windows 10 no Hyper-V"
find the new id of the just created "Windows 10 no Hyper-V" bootentry, eg. {094a0b01-3350-11e7-99e1-bc5ec82bc470}
bcdedit /set {094a0b01-3350-11e7-99e1-bc5ec82bc470} hypervisorlaunchtype Off
After rebooting you can choose between Windows 10 with and without Hyper-V at startup
Unit test is usually done for a single functionality implemented in Software module. The scope of testing is entirely within this SW module. Unit test never fulfils the final functional requirements. It comes under whitebox testing methodology..
Whereas Integration test is done to ensure the different SW module implementations. Testing is usually carried out after module level integration is done in SW development.. This test will cover the functional requirements but not enough to ensure system validation.
Agree @Drixson Oseña: You should not write localhost/xampp/...., else write for e.g: localhost/mw-config/index.php
This one-liner should work too:
(cd /path/to/your/app && npm start)
Note that the current directory will be changed to /path/to/your/app after executing this command. To preserve the working directory:
(cd /path/to/your/app && npm start && cd -)
I used this solution because a program configuration file I was editing back then didn't support specifying command line arguments.
@jennifer06262016, you can definitely add another filter to return the objects inside a django Queryset.
@register.filter
def get_item(Queryset):
return Queryset.your_item_key
In that case, you would type something like this {{ Queryset|index:x|get_item }} into your template to access some dictionary object. It works for me.
We can use this. Please change the src location of ur img from git folder and add alternate text if img is not loaded
<p align="center">
<img src="ur img url here" alt="alternate text">
</p>
You can write the function this way also Which helps to build your code one time just to add class name or ID at the end
function equalHeight(group) {
tallest = 0;
group.each(function() {
thisHeight = jQuery(this).height();
if(thisHeight > tallest) {
tallest = thisHeight;
}
});
group.height(tallest);
}
equalHeight(jQuery("Add your class"));
In my case, the table's id column was not set as an Identity column.
You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model
Post.objects.all().delete()
and to delete any Post with a future publication date
Post.objects.filter(pub_date__gt=datetime.now()).delete()
You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.
EDIT:
Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForm
s and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.
fig = plt.figure()
ax = fig.add_subplot(111)
plt.xticks([0.4,0.14,0.2,0.2], fontsize = 50) # work on current fig
plt.show()
the x/yticks has the same properties as matplotlib.text
With Android 8.0 using Custom Fonts in Application became easy with downloadable fonts
.
We can add fonts directly to the res/font/ folder
in the project folder, and in doing so, the fonts become automatically available in Android Studio.
Now set fontFamily
attribute to list of fonts or click on more and select font of your choice. This will add tools:fontFamily="@font/your_font_file"
line to your TextView.
This will Automatically generate few files.
1. In values folder it will create fonts_certs.xml
.
2. In Manifest it will add this lines:
<meta-data
android:name="preloaded_fonts"
android:resource="@array/preloaded_fonts" />
3.
preloaded_fonts.xml
<resources>
<array name="preloaded_fonts" translatable="false">
<item>@font/open_sans_regular</item>
<item>@font/open_sans_semibold</item>
</array>
</resources>

css href link is incorrect. Use relative path instead:
<link href="../css/loginstyle.css" rel="stylesheet" type="text/css">

file.name # Gives name
file.content_type # Gives Content type text/html etc
file.size # Gives file's size in byte
file.read() # Reads file
Putting the various suggestions together, the cleanest version I was able to come up with (without unreliable grep which triggers parts of words) is:
kill -0 $(pidof mysql) 2> /dev/null || echo "Mysql ain't runnin' message/actions"
kill -0 doesn't kill the process but checks if it exists and then returns true, if you don't have pidof on your system, store the pid when you launch the process:
$ mysql &
$ echo $! > pid_stored
then in the script:
kill -0 $(cat pid_stored) 2> /dev/null || echo "Mysql ain't runnin' message/actions"
Simple like this:
import math
def my_cdf(x):
return 0.5*(1+math.erf(x/math.sqrt(2)))
I found the formula in this page https://www.danielsoper.com/statcalc/formulas.aspx?id=55
You can use white-space: nowrap;
to define this behaviour:
// HTML:
.nowrap {_x000D_
white-space: nowrap ;_x000D_
}
_x000D_
<p>_x000D_
<span class="nowrap">How do I wrap this line of text</span>_x000D_
<span class="nowrap">- asked by Peter 2 days ago</span>_x000D_
</p>
_x000D_
// CSS:
.nowrap {
white-space: nowrap ;
}
Try:
psql -U role_name -d database -h hostname..com -W
@Query("select u from user u where u.username LIKE :username")
List<User> findUserByUsernameLike(@Param("username") String username);
Leave your email.php code the same, but replace this JavaScript code:
var name = $("#form_name").val();
var email = $("#form_email").val();
var text = $("#msg_text").val();
var dataString = 'name='+ name + '&email=' + email + '&text=' + text;
$.ajax({
type: "POST",
url: "email.php",
data: dataString,
success: function(){
$('.success').fadeIn(1000);
}
});
with this:
$.ajax({
type: "POST",
url: "email.php",
data: $(form).serialize(),
success: function(){
$('.success').fadeIn(1000);
}
});
So that your form input names match up.
Try this:
input[type="radio"] {
margin-top: -1px;
vertical-align: middle;
}
Try using Sublime Package Control to install your packages.

I'm sure Don Box created SOAP as a joke - 'look you can call RPC methods over the web' and today groans when he realises what a bloated nightmare of web standards it has become :-)
REST is good, simple, implemented everywhere (so more a 'standard' than the standards) fast and easy. Use REST.
Don't like any of those solutions.
this is how i do it:
$update_query = "UPDATE db.tablename SET insert_time=now() WHERE username='"
. sqlEsc($somename) . "' ;";
then i use my own sqlEsc function:
function sqlEsc($val)
{
global $mysqli;
return mysqli_real_escape_string($mysqli, $val);
}
This will create a Date
exactly one year in the future with just one line. First we get the fullYear
from a new Date
, increment it, set that as the year of a new Date
. You might think we'd be done there, but if we stopped it would return a timestamp, not a Date
object so we wrap the whole thing in a Date
constructor.
new Date(new Date().setFullYear(new Date().getFullYear() + 1))
Use the getResourceAsStream()
method on the ServletContext object, e.g.
servletContext.getResourceAsStream("/WEB-INF/myfile");
How you get a reference to the ServletContext depends on your application... do you want to do it from a Servlet or from a JSP?
EDITED: If you're inside a Servlet object, then call getServletContext()
. If you're in JSP, use the predefined variable application
.
Under TortoiseSVN, see the following page: http://tortoisesvn.net/docs/release/TortoiseSVN_en/tsvn-dug-copy.html
A fundamental mistake is here:
result = methodInfo.Invoke(methodInfo, parametersArray);
You are invoking the method on an instance of MethodInfo
. You need to pass in an instance of the type of object that you want to invoke on.
result = methodInfo.Invoke(classInstance, parametersArray);
This should do the trick:
$('#thisElement').find('.classToSelect')
This also works
SELECT *

WHERE ID NOT IN (
SELECT ID FROM tableA

If you care about the command's error output you can separate them like this while still using the built-in time command.
{ time your_command 2> command.err ; } 2> time.log
or
{ time your_command 2>1 ; } 2> time.log
As you see the command's errors go to a file (since stderr
is used for time
).
Unfortunately you can't send it to another handle (like 3>&2
) since that will not exist anymore outside the {...}
That said, if you can use GNU time, just do what @Tim Ludwinski said.
\time -o time.log command
One option is to put the subquery in a LEFT JOIN
:
select sum ( t.graduates ) - t1.summedGraduates
from table as t
left join
(
select sum ( graduates ) summedGraduates, id
from table
where group_code not in ('total', 'others' )
group by id
) t1 on t.id = t1.id
where t.group_code = 'total'
group by t1.summedGraduates
Perhaps a better option would be to use SUM
with CASE
:
select sum(case when group_code = 'total' then graduates end) -
sum(case when group_code not in ('total','others') then graduates end)
from yourtable
According to CodeGuru:
CString
to std::string
:
CString cs("Hello");
std::string s((LPCTSTR)cs);
BUT: std::string
cannot always construct from a LPCTSTR
. i.e. the code will fail for UNICODE builds.
As std::string
can construct only from LPSTR
/ LPCSTR
, a programmer who uses VC++ 7.x or better can utilize conversion classes such as CT2CA
as an intermediary.
CString cs ("Hello");
// Convert a TCHAR string to a LPCSTR
CT2CA pszConvertedAnsiString (cs);
// construct a std::string using the LPCSTR input
std::string strStd (pszConvertedAnsiString);
std::string
to CString
: (From Visual Studio's CString FAQs...)
std::string s("Hello");
CString cs(s.c_str());
CStringT
can construct from both character or wide-character strings. i.e. It can convert from char*
(i.e. LPSTR
) or from wchar_t*
(LPWSTR
).
In other words, char-specialization (of CStringT
) i.e. CStringA
, wchar_t
-specilization CStringW
, and TCHAR
-specialization CString
can be constructed from either char
or wide-character, null terminated (null-termination is very important here) string sources.
Althoug IInspectable amends the "null-termination" part in the comments:
NUL-termination is not required.
CStringT
has conversion constructors that take an explicit length argument. This also means that you can constructCStringT
objects fromstd::string
objects with embeddedNUL
characters.
Found these docu on the google docu pages:
In your example, you would get (if you picked the 3rd row) "C3:O3", cause C --> O is 12 columns
edit
Using the example on the docu:
// The code below will get the number of columns for the range C2:G8
// in the active spreadsheet, which happens to be "4"
var count = SpreadsheetApp.getActiveSheet().getRange(2, 3, 6, 4).getNumColumns(); Browser.msgBox(count);
The values between brackets:
2: the starting row = 2
3: the starting col = C
6: the number of rows = 6 so from 2 to 8
4: the number of cols = 4 so from C to G
So you come to the range: C2:G8

Check if your commits have Change-Id: ...
in their descriptions. Every commit should have them.
If no, use git rebase -i
to reword the commit messages and add proper Change-Ids (usually this is a SHA1 of the first version of the reviewed commit).
For the future, you should install commit hook, which automatically adds the required Change-Id.
Execute scp -p -P 29418 username@your_gerrit_address:hooks/commit-msg .git/hooks/
in the repository directory
or download them from
http://your_gerrit_address/tools/hooks/commit-msg
and copy to .git/hooks
Here is the function:
document.body.setScaledFont = function(f) {
var s = this.offsetWidth, fs = s * f;
this.style.fontSize = fs + '%';
return this
};
Then convert all your documents child element font sizes to em's or %.
Then add something like this to your code to set the base font size.
document.body.setScaledFont(0.35);
window.onresize = function() {
document.body.setScaledFont(0.35);
}
Fail module works great! Thanks.
I had to define my fact before checking it, otherwise I'd get an undefined variable error.
And I had issues when doing setting the fact with quotes and without spaces.
This worked:
set_fact: flag="failed"
This threw errors:
set_fact: flag = failed
The semantics of C# differs slightly from Java here. In C# assignment in declaration is performed before calling the superclass constructor. In Java it is done immediately after which allows 'this' to be used (particularly useful for anonymous inner classes), and means that the semantics of the two forms really do match.
If you can, make the fields final.
This answer is an attempt at a technical answer rather than opinion.
If we want to be POSIX purists, we define a line as:
A sequence of zero or more non- <newline> characters plus a terminating <newline> character.
Source: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_206
An incomplete line as:
A sequence of one or more non- <newline> characters at the end of the file.
Source: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_195
A text file as:
A file that contains characters organized into zero or more lines. The lines do not contain NUL characters and none can exceed {LINE_MAX} bytes in length, including the <newline> character. Although POSIX.1-2008 does not distinguish between text files and binary files (see the ISO C standard), many utilities only produce predictable or meaningful output when operating on text files. The standard utilities that have such restrictions always specify "text files" in their STDIN or INPUT FILES sections.
Source: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_397
A string as:
A contiguous sequence of bytes terminated by and including the first null byte.
Source: https://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap03.html#tag_03_396
From this then, we can derive that the only time we will potentially encounter any type of issues are if we deal with the concept of a line of a file or a file as a text file (being that a text file is an organization of zero or more lines, and a line we know must terminate with a <newline>).
Case in point: wc -l filename
.
From the wc
's manual we read:
A line is defined as a string of characters delimited by a <newline> character.
What are the implications to JavaScript, HTML, and CSS files then being that they are text files?
In browsers, modern IDEs, and other front-end applications there are no issues with skipping EOL at EOF. The applications will parse the files properly. It has to since not all Operating Systems conform to the POSIX standard, so it would be impractical for non-OS tools (e.g. browsers) to handle files according to the POSIX standard (or any OS-level standard).
As a result, we can be relatively confident that EOL at EOF will have virtually no negative impact at the application level - regardless if it is running on a UNIX OS.
At this point we can confidently say that skipping EOL at EOF is safe when dealing with JS, HTML, CSS on the client-side. Actually, we can state that minifying any one of these files, containing no <newline> is safe.
We can take this one step further and say that as far as NodeJS is concerned it too cannot adhere to the POSIX standard being that it can run in non-POSIX compliant environments.
What are we left with then? System level tooling.
This means the only issues that may arise are with tools that make an effort to adhere their functionality to the semantics of POSIX (e.g. definition of a line as shown in wc
).
Even so, not all shells will automatically adhere to POSIX. Bash for example does not default to POSIX behavior. There is a switch to enable it: POSIXLY_CORRECT
.
Food for thought on the value of EOL being <newline>: https://www.rfc-editor.org/old/EOLstory.txt
Staying on the tooling track, for all practical intents and purposes, let's consider this:
Let's work with a file that has no EOL. As of this writing the file in this example is a minified JavaScript with no EOL.
curl http://cdnjs.cloudflare.com/ajax/libs/AniJS/0.5.0/anijs-min.js -o x.js
curl http://cdnjs.cloudflare.com/ajax/libs/AniJS/0.5.0/anijs-min.js -o y.js
$ cat x.js y.js > z.js
-rw-r--r-- 1 milanadamovsky 7905 Aug 14 23:17 x.js
-rw-r--r-- 1 milanadamovsky 7905 Aug 14 23:17 y.js
-rw-r--r-- 1 milanadamovsky 15810 Aug 14 23:18 z.js
Notice the cat
file size is exactly the sum of its individual parts. If the concatenation of JavaScript files is a concern for JS files, the more appropriate concern would be to start each JavaScript file with a semi-colon.
As someone else mentioned in this thread: what if you want to cat
two files whose output becomes just one line instead of two? In other words, cat
does what it's supposed to do.
The man
of cat
only mentions reading input up to EOF, not <newline>. Note that the -n
switch of cat
will also print out a non- <newline> terminated line (or incomplete line) as a line - being that the count starts at 1 (according to the man
.)
-n Number the output lines, starting at 1.
Now that we understand how POSIX defines a line , this behavior becomes ambiguous, or really, non-compliant.
Understanding a given tool's purpose and compliance will help in determining how critical it is to end files with an EOL. In C, C++, Java (JARs), etc... some standards will dictate a newline for validity - no such standard exists for JS, HTML, CSS.
For example, instead of using wc -l filename
one could do awk '{x++}END{ print x}' filename
, and rest assured that the task's success is not jeopardized by a file we may want to process that we did not write (e.g. a third party library such as the minified JS we curl
d) - unless our intent was truly to count lines in the POSIX compliant sense.
Conclusion
There will be very few real life use cases where skipping EOL at EOF for certain text files such as JS, HTML, and CSS will have a negative impact - if at all. If we rely on <newline> being present, we are restricting the reliability of our tooling only to the files that we author and open ourselves up to potential errors introduced by third party files.
Moral of the story: Engineer tooling that does not have the weakness of relying on EOL at EOF.
Feel free to post use cases as they apply to JS, HTML and CSS where we can examine how skipping EOL has an adverse effect.
Does this help?
This property returns all the attributes of an element into an array for you. Here is an example.
window.addEventListener('load', function() {_x000D_
var result = document.getElementById('result');_x000D_
var spanAttributes = document.getElementsByTagName('span')[0].attributes;_x000D_
for (var i = 0; i != spanAttributes.length; i++) {_x000D_
result.innerHTML += spanAttributes[i].value + ',';_x000D_
}_x000D_
});
_x000D_
<span name="test" message="test2"></span>_x000D_
<div id="result"></div>
_x000D_
To get the attributes of many elements and organize them, I suggest making an array of all the elements that you want to loop through and then create a sub array for all the attributes of each element looped through.
This is an example of a script that will loop through the collected elements and print out two attributes. This script assumes that there will always be two attributes but you can easily fix this with further mapping.
window.addEventListener('load',function(){_x000D_
/*_x000D_
collect all the elements you want the attributes_x000D_
for into the variable "elementsToTrack"_x000D_
*/ _x000D_
var elementsToTrack = $('body span, body div');_x000D_
//variable to store all attributes for each element_x000D_
var attributes = [];_x000D_
//gather all attributes of selected elements_x000D_
for(var i = 0; i != elementsToTrack.length; i++){_x000D_
var currentAttr = elementsToTrack[i].attributes;_x000D_
attributes.push(currentAttr);_x000D_
}_x000D_
_x000D_
//print out all the attrbute names and values_x000D_
var result = document.getElementById('result');_x000D_
for(var i = 0; i != attributes.length; i++){_x000D_
result.innerHTML += attributes[i][0].name + ', ' + attributes[i][0].value + ' | ' + attributes[i][1].name + ', ' + attributes[i][1].value +'<br>'; _x000D_

Remember that sizes on the web are increasing dramatically. 3 years ago, I did an overhaul to bring our 500 px wide site layout to 1000. Now, where many sites are doing the jump to 1200, we jumped past that and went to a 2560 max optimized for 1600 wide (or 80% depending on the content level) main content area with responsiveness to allow the exact same ratios and look and feel on a laptop (1366x768) and on mobile (1280x720 or smaller).
Dynamic resizing is an integral part of this and will only become more-so as responsiveness becomes more and more important in 2013.
My smartphone has no trouble dealing with the content with 25 items on a page being resized - neither the computation for resizing nor the bandwidth. 3 seconds loads the page from fresh. Looks great on our 6 year old presentation laptop (1366x768) and on the projector (800x600).
Only on Mozilla Firefox does it look genuinely atrocious. It even looks just fine on IE8 (never used/updated since I installed it 2.5 years ago).

Your error might be because of the merge branch.
Just follow this:
step 1 : git pull origin master
(in case if you get any message then ignore it)
step 2 : git add .
step 3 : git commit -m 'your commit message'
step 4 : git push origin master
The term 'slug' comes from the world of newspaper production.
It's an informal name given to a story during the production process. As the story winds its path from the beat reporter (assuming these even exist any more?) through to editor through to the "printing presses", this is the name it is referenced by, e.g., "Have you fixed those errors in the 'kate-and-william' story?".
Some systems (such as Django) use the slug as part of the URL to locate the story, an example being www.mysite.com/archives/kate-and-william
.
Even Stack Overflow itself does this, with the GEB-ish(a) self-referential https://stackoverflow.com/questions/427102/what-is-a-slug-in-django/427201#427201
, although you can replace the slug with blahblah
and it will still find it okay.
It may even date back earlier than that, since screenplays had "slug lines" at the start of each scene, which basically sets the background for that scene (where, when, and so on). It's very similar in that it's a precis or preamble of what follows.
On a Linotype machine, a slug was a single line piece of metal which was created from the individual letter forms. By making a single slug for the whole line, this greatly improved on the old character-by-character compositing.
Although the following is pure conjecture, an early meaning of slug was for a counterfeit coin (which would have to be pressed somehow). I could envisage that usage being transformed to the printing term (since the slug had to be pressed using the original characters) and from there, changing from the 'piece of metal' definition to the 'story summary' definition. From there, it's a short step from proper printing to the online world.

I am not sure but you can try intialising handler to null in onDestroy()
You should be able to do this like (as you're using the query api):
Entrant.where("pincode").ne(null)
... which will result in a mongo query resembling:
entrants.find({ pincode: { $ne: null } })

In IIS you can declare the mime type for WOFF2 font files by adding the following to your project's web.config:
<system.webServer>
<staticContent>
<remove fileExtension=".woff2" />
<mimeMap fileExtension=".woff2" mimeType="font/woff2" />
</staticContent>
</system.webServer>
Update:
The mime type may be changing according to the latest W3C Editor's Draft WOFF2 spec. See Appendix A: Internet Media Type Registration section 6.5. WOFF 2.0 which states the latest proposed format is font/woff2
Firstly, check that you're using the same accounts in both Application Loaded (or XCode) and iTunes connect. Secondly, check that Bundle Id in error message and in iTunes connect are match, including tHe cAsE!
There are several ways that you can transform data from multiple rows into columns.
PIVOT
In SQL Server you can use the PIVOT
function to transform the data from rows to columns:
select Firstname, Amount, PostalCode, LastName, AccountNumber
from
(
select value, columnname
from yourtable
) d
pivot
(
max(value)
for columnname in (Firstname, Amount, PostalCode, LastName, AccountNumber)
) piv;
See Demo.
columnnames
If you have an unknown number of columnnames
that you want to transpose, then you can use dynamic SQL:
DECLARE @cols AS NVARCHAR(MAX),
@query AS NVARCHAR(MAX)
select @cols = STUFF((SELECT ',' + QUOTENAME(ColumnName)
from yourtable
group by ColumnName, id
order by id
FOR XML PATH(''), TYPE
).value('.', 'NVARCHAR(MAX)')
,1,1,'')
set @query = N'SELECT ' + @cols + N' from
(
select value, ColumnName
from yourtable
) x
pivot
(
max(value)
for ColumnName in (' + @cols + N')
) p '
exec sp_executesql @query;
See Demo.
If you do not want to use the PIVOT
function, then you can use an aggregate function with a CASE
expression:
select
max(case when columnname = 'FirstName' then value end) Firstname,
max(case when columnname = 'Amount' then value end) Amount,
max(case when columnname = 'PostalCode' then value end) PostalCode,
max(case when columnname = 'LastName' then value end) LastName,
max(case when columnname = 'AccountNumber' then value end) AccountNumber
from yourtable
See Demo.
This could also be completed using multiple joins, but you will need some column to associate each of the rows which you do not have in your sample data. But the basic syntax would be:
select fn.value as FirstName,
a.value as Amount,
pc.value as PostalCode,
ln.value as LastName,
an.value as AccountNumber
from yourtable fn
left join yourtable a
on fn.somecol = a.somecol
and a.columnname = 'Amount'
left join yourtable pc
on fn.somecol = pc.somecol
and pc.columnname = 'PostalCode'
left join yourtable ln
on fn.somecol = ln.somecol
and ln.columnname = 'LastName'
left join yourtable an
on fn.somecol = an.somecol
and an.columnname = 'AccountNumber'
where fn.columnname = 'Firstname'
In more modern browsers (including IE 10+) you can now use calc()
:
.moveto {
top: 0px;
left: calc(100% - 50px);
}
You can achive this with creating new array:
<?php
$array = array(1 => "Toyota", 2 => "Nissan", 3 => "BMW");
if (isset ($_POST['search'])) {
$maker = mysql_real_escape_string($_POST['Make']);
echo $array[$maker];
}
?>
Run the following query:
use mysql;
update user set host='%' where host='localhost'
NOTE: Not recommended for production use.
I had a very messy cody that loaded facebook's javascript via AJAX and i had to make sure that the js file has been completely loaded before calling FB.init this seem to work for me
$jQuery.load( document.location.protocol + '//connect.facebook.net/en_US/all.js',
function (obj) {
FB.init({
appId : 'YOUR APP ID',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
//ANy other FB.related javascript here
});
This code uses jquery to load the javascript and do the function callback onLoad of the javascript. it's a lot less messier than having creating an onLoad eventlistener for the block which in the end didn't work very well on IE6, 7 and 8
On input:
step="any"
class="two-decimals"
On script:
$(".two-decimals").change(function(){
this.value = parseFloat(this.value).toFixed(2);
});
Just created this:

Storage.setObj('users.albums.sexPistols',{ sid : "My Way", nancy : "Bitch" });
Storage.setObj('users.albums.sexPistols.sid',"Other songs");
//Getters
Storage.getObj('users');
Storage.getObj('users.albums');
Storage.getObj('users.albums.sexPistols');
Storage.getObj('users.albums.sexPistols.sid');
Storage.getObj('users.albums.sexPistols.nancy');
