If you have multiple Action within same file then pass the same argument e.g. Id to all Action. This is because action only can identify Id, So instead of giving any name to argument only declare Id like this.
[httpget]
[ActionName("firstAction")] firstAction(string Id)
{.....
.....
}
[httpget]
[ActionName("secondAction")] secondAction(Int Id)
{.....
.....
}
//Now go to webroute.config file under App-start folder and add following
routes.MapHttpRoute(
name: "firstAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
routes.MapHttpRoute(
name: "secondAction",
routeTemplate: "api/{controller}/{action}/{id}",
defaults: new { id = RouteParameter.Optional }
);
For more modularity and in case you have many background images that you want to incorporate wherever you want you can for each image create a class :
.background-image1
{
background: url(image1.jpg);
}
.background-image2
{
background: url(image2.jpg);
}
and then insert the image wherever you want by adding a div
<div class='background-image1'>
<div class="page-header text-center", style='margin: 20px 0 0px;'>
<h1>blabaaboabaon</h1>
</div>
</div>
Make sure your code is in DOM Ready as pointed by rocket-hazmat
$('#RootNode').click(function(){
//do something
});
document.getElementById("RootNode").onclick = function(){//do something}
$(document).on("click", "#RootNode", function(){
//do something
});
Wrap Code in Dom Ready
$(document).ready(function(){
$('#RootNode').click(function(){
//do something
});
});
final
can be used to mark a variable "unchangeable"
private final String name = "foo"; //the reference name can never change
final
can also make a method not "overrideable"
public final String toString() { return "NULL"; }
final
can also make a class not "inheritable". i.e. the class can not be subclassed.
public final class finalClass {...}
public class classNotAllowed extends finalClass {...} // Not allowed
finally
is used in a try/catch statement to execute code "always"
lock.lock();
try {
//do stuff
} catch (SomeException se) {
//handle se
} finally {
lock.unlock(); //always executed, even if Exception or Error or se
}
Java 7 has a new try with resources statement that you can use to automatically close resources that explicitly or implicitly implement java.io.Closeable or java.lang.AutoCloseable
finalize
is called when an object is garbage collected. You rarely need to override it. An example:
protected void finalize() {
//free resources (e.g. unallocate memory)
super.finalize();
}
Another possible answer for Windows 10:
The command httpd -k restart
does not work on my machine somehow.
Try to use the Windows 10 Service to restart the relative service.
I know it's an old post but I had the same issue today, what I did is simple : changing my script that send my playbook from my local host to the server, before sending it with maven command, I did this :
cat common_vars.yml > vars.yml
cat snapshot_vars.yml >> vars.yml
# or
#cat release_vars.yml >> vars.yml
mvn ....
Just to elaborate on Bhavin's excellent answer - editing the solution file works but you may still get the incompatible error (as David reported) if you had .NET 4.5 selected as the default .NET version in your VS2012 project and your VS2010 enviroment doesn't support that.
To quickly fix that, open the VS2012 .csproj file in a text editor and change the TargetFrameworkVersion down to 4.0 (from 4.5). VS2010 will then happily load the "edited" solution and projects.
You'll also have to edit an app.config files that have references to .NET 4.5 in a similar way to allow them to run on a .NET 4.0 environment.
Why not recursive ?

Under Windows 7 I had anaconda and anaconda3 installed.
I went into \Users\me\anaconda\Scripts
and executed
sudo .\ipython kernelspec install-self
then I went into \Users\me\anaconda3\Scripts
and executed
sudo .\ipython kernel install
(I got jupyter kernelspec install-self is DEPRECATED as of 4.0. You probably want 'ipython kernel install' to install the IPython kernelspec.
)
After starting jupyter notebook
(in anaconda3) I got a neat dropdown menu in the upper right corner under "New" letting me choose between Python 2 odr Python 3 kernels.
Use this code in your php script (first lines)
ini_set('allow_url_fopen',1);
If your switch Install by USB on and you are getting "the device is temporarily restricted" error, then apply any of the default mobile themes. If any other developer theme is applied then it will not Allow you to switch Install by USB on. This works for me.
As the error idnicates - "This happens when the section is locked at a parent level". To unlock the section you can use appcmd.exe and execute the following command:
%windir%\system32\inetsrv\appcmd.exe unlock config -section:system.webServer/handlers -commitpath:apphost
For more information on about section locking and what a parent configuration context is refer to IIS documentation.
Just a side note, in Python 2.0 you could compare anything to anything (int to string). As this wasn't explicit, it was changed in 3.0, which is a good thing as you are not running into the trouble of comparing senseless values with each other or when you forget to convert a type.
Try this, In your onCreate()
getActionBar().setHomeButtonEnabled(true);
getActionBar().setDisplayHomeAsUpEnabled(true);
And for clickevent,

case android.R.id.home:
// app icon in action bar clicked; goto parent activity.
this.finish();
return true;

If you run sql server 2012 you can get this error by trying to attach an older version of an mdf-file. ex an mdf file from sql server 2008.
Yes, you can use Application.OnTime
for this and then put it in a loop. It's sort of like an alarm clock where you keep hittig the snooze button for when you want it to ring again. The following updates Cell A1 every three seconds with the time.
Dim TimerActive As Boolean
Sub StartTimer()
Start_Timer
End Sub
Private Sub Start_Timer()
TimerActive = True
Application.OnTime Now() + TimeValue("00:00:03"), "Timer"
End Sub
Private Sub Stop_Timer()
TimerActive = False
End Sub
Private Sub Timer()
If TimerActive Then
ActiveSheet.Cells(1, 1).Value = Time
Application.OnTime Now() + TimeValue("00:00:03"), "Timer"
End If
End Sub
You can put the StartTimer
procedure in your Auto_Open
event and change what is done in the Timer
proceedure (right now it is just updating the time in A1 with ActiveSheet.Cells(1, 1).Value = Time
).
Note: you'll want the code (besides StartTimer
) in a module, not a worksheet module. If you have it in a worksheet module, the code requires slight modification.
This is what I typically do:
File outputDir = context.getCacheDir(); // context being the Activity pointer
File outputFile = File.createTempFile("prefix", "extension", outputDir);
As for their deletion, I am not complete sure either. Since I use this in my implementation of a cache, I manually delete the oldest files till the cache directory size comes down to my preset value.
This should solve your problem:
td {

* left, right, center, justify, inherit
*/
text-align: center;
/* <http://www.w3.org/wiki/CSS/Properties/vertical-align>
* baseline, sub, super, top, text-top, middle,
* bottom, text-bottom, length, or a value in percentage
*/
vertical-align: top;
}
This is a bit late, but I just stumbled on this problem, trying to resolve my own problem of this kind. I then realized that I had this line in the ajax post wrong:
data: "{'quantity' : " + total_qty + ",'itemId':" + itemId + "}",
It should be:
data: "{quantity : '" + total_qty + "',itemId: '" + itemId + "'}",
As well as the WebMethod to:
public static string AddTo_Cart(string quantity, string itemId)
And this resolved my problem.
Hope it may be of help to someone else as well.
It probably aimed to select all the informations in your table. If you use this kind of query (for example in PHP) :
mysql_query("SELECT * FROM newsletter WHERE email = '$email'");
The email ' OR 1=1/* will give this kind of query :
mysql_query("SELECT * FROM newsletter WHERE email = '' OR 1=1/*");
So it selects all the rows (because 1=1 is always true and the rest of the query is 'commented'). But it was not successful
I found this funny example in terms of loose coupling:
Source: Understanding dependency injection
Any application is composed of many objects that collaborate with each other to perform some useful stuff. Traditionally each object is responsible for obtaining its own references to the dependent objects (dependencies) it collaborate with. This leads to highly coupled classes and hard-to-test code.
For example, consider a Car
object.
A Car
depends on wheels, engine, fuel, battery, etc. to run. Traditionally we define the brand of such dependent objects along with the definition of the Car
object.
Without Dependency Injection (DI):
class Car{
private Wheel wh = new NepaliRubberWheel();
private Battery bt = new ExcideBattery();
//The rest
}
Here, the Car
object is responsible for creating the dependent objects.
What if we want to change the type of its dependent object - say Wheel
- after the initial NepaliRubberWheel()
punctures?
We need to recreate the Car object with its new dependency say ChineseRubberWheel()
, but only the Car
manufacturer can do that.
Then what does the Dependency Injection
do for us...?
When using dependency injection, objects are given their dependencies at run time rather than compile time (car manufacturing time).
So that we can now change the Wheel
whenever we want. Here, the dependency
(wheel
) can be injected into Car
at run time.
After using dependency injection:
Here, we are injecting the dependencies (Wheel and Battery) at runtime. Hence the term : Dependency Injection. We normally rely on DI frameworks such as Spring, Guice, Weld to create the dependencies and inject where needed.
class Car{
private Wheel wh; // Inject an Instance of Wheel (dependency of car) at runtime
private Battery bt; // Inject an Instance of Battery (dependency of car) at runtime
Car(Wheel wh,Battery bt) {
this.wh = wh;
this.bt = bt;
}
//Or we can have setters
void setWheel(Wheel wh) {
this.wh = wh;
}
}
The advantages are:
The short answer - No.
The long answer - no, since the code relies on the presence of a SMTP server running on the local machine, and listening on port 25. The SMTP server (technically the MTA or Mail Transfer Agent) is responsible for communicating with the Mail User Agent (MUA, which in this case is the Java process) to receive outgoing emails.
Now, MTAs are typically responsible for receiving mails from users for a particular domain. So, for the domain gmail.com, it would be the Google mail servers that are responsible for authenticating mail user agents and hence transferring of mails to inboxes on the GMail servers. I'm not sure if GMail trusts open mail relay servers, but it is certainly not an easy task to perform authentication on behalf on Google, and then relay mail to the GMail servers.
If you read the JavaMail FAQ on using JavaMail to accessing GMail, you'll notice that the hostname and the port happen to be pointing to the GMail servers, and certainly not to localhost. If you intend to use your local machine, you'll need to perform either relaying or forwarding.
You'll probably need to understand the SMTP protocol in depth if you intend to get anywhere when it comes to SMTP. You can start with the Wikipedia article on SMTP, but any further progress will actually necessitate programming against a SMTP server.
You've added an extra level of abstraction by calling the method with reflection. The reflection layer wraps any exception in an InvocationTargetException
, which lets you tell the difference between an exception actually caused by a failure in the reflection call (maybe your argument list wasn't valid, for example) and a failure within the method called.
Just unwrap the cause within the InvocationTargetException
and you'll get to the original one.
You should change your code to make use of SqlParameters and adapt your insert statement to the following
string connetionString = "Data Source=UMAIR;Initial Catalog=Air; Trusted_Connection=True;" ;
// [ ] required as your fields contain spaces!!
string insStmt = "insert into Main ([First Name], [Last Name]) values (@firstName,@lastName)";
using (SqlConnection cnn = new SqlConnection(connetionString))
{
cnn.Open();
SqlCommand insCmd = new SqlCommand(insStmt, cnn);
// use sqlParameters to prevent sql injection!
insCmd.Parameters.AddWithValue("@firstName", textbox2.Text);
insCmd.Parameters.AddWithValue("@lastName", textbox3.Text);
int affectedRows = insCmd.ExecuteNonQuery();
MessageBox.Show (affectedRows + " rows inserted!");
}
You should set layout first by syntax pnlButton.setLayout()
, and then choose the most suitable layout which u want. Ex: pnlButton.setLayout(new FlowLayout(FlowLayout.LEADING, 5, 5));
. And then, take that JButton into JPanel.
You can also use the void operator to obtain an undefined value:
if (input !== void 0) {
// do stuff
}
(And yes, as noted in another answer, this will throw an error if the variable was not declared, but this case can often be ruled out either by code inspection, or by code refactoring, e.g. using window.input !== void 0
for testing global variables or adding var input
.)
You should android:layout_margin<Side>
on the children. Padding is internal.
Empty returns true if the var is not set. But isset returns true even if the var is not empty.
You can't call a Javascript function from the CodeBehind, because the CodeBehind file contains the code that executes server side on the web server. Javascript code executes in the web browser on the client side.

textView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -20),
textView.heightAnchor.constraint(greaterThanOrEqualToConstant: 150),

You can use Charset.defaultCharset()
API or file.encoding
property.
But if you want your own constant, you'll need to define it yourself.
In case you have multiple images and you want to loop though them and show them 1 by 1 along with titles - this is what you can do. No need to explicitly define ax1, ax2, etc.
import matplotlib.pyplot as plt
fig, ax = plt.subplots(2, 2, figsize=(6, 8))
for i in range(len(ax)):
for j in range(len(ax[i])):
## ax[i,j].imshow(test_images_gr[0].reshape(28,28))
ax[i,j].set_title('Title-' + str(i) + str(j))

I did quite a bit of investigation on that topic recently since I was not satisfied with the many libraries I found out there.
I ended up developing a library to address this, it is named valid8. As explained in the documentation, it is for value validation mostly (although it comes bundled with simple type validation functions too), and you might wish to associate it with a PEP484-based type checker such as enforce or pytypes.
This is how you would perform validation with valid8
alone (and mini_lambda
actually, to define the validation logic - but it is not mandatory) in your case:
# for type validation
from numbers import Integral
from valid8 import instance_of
# for value validation
from valid8 import validate_arg
from mini_lambda import x, s, Len
@validate_arg('a', instance_of(Integral))
@validate_arg('b', (0 < x) & (x < 10))
@validate_arg('c', instance_of(str), Len(s) > 0)
def my_function(a: Integral, b, c: str):
"""an example function I'd like to check the arguments of."""
# check that a is an int
# check that 0 < b < 10
# check that c is not an empty string
# check that it works
my_function(0.2, 1, 'r') # InputValidationError for 'a' HasWrongType: Value should be an instance of <class 'numbers.Integral'>. Wrong value: [0.2].
my_function(0, 0, 'r') # InputValidationError for 'b' [(x > 0) & (x < 10)] returned [False]
my_function(0, 1, 0) # InputValidationError for 'c' Successes: [] / Failures: {"instance_of_<class 'str'>": "HasWrongType: Value should be an instance of <class 'str'>. Wrong value: [0]", 'len(s) > 0': "TypeError: object of type 'int' has no len()"}.
my_function(0, 1, '') # InputValidationError for 'c' Successes: ["instance_of_<class 'str'>"] / Failures: {'len(s) > 0': 'False'}
And this is the same example leveraging PEP484 type hints and delegating type checking to enforce
:
# for type validation
from numbers import Integral
from enforce import runtime_validation, config
config(dict(mode='covariant')) # type validation will accept subclasses too
# for value validation
from valid8 import validate_arg
from mini_lambda import x, s, Len
@runtime_validation
@validate_arg('b', (0 < x) & (x < 10))
@validate_arg('c', Len(s) > 0)
def my_function(a: Integral, b, c: str):
"""an example function I'd like to check the arguments of."""
# check that a is an int
# check that 0 < b < 10
# check that c is not an empty string
# check that it works
my_function(0.2, 1, 'r') # RuntimeTypeError 'a' was not of type <class 'numbers.Integral'>
my_function(0, 0, 'r') # InputValidationError for 'b' [(x > 0) & (x < 10)] returned [False]
my_function(0, 1, 0) # RuntimeTypeError 'c' was not of type <class 'str'>
my_function(0, 1, '') # InputValidationError for 'c' [len(s) > 0] returned [False].
There shouldn't be any LINQ magic keeping you from doing this. Don't use projection though that'll return an anonymous type.
User u = UserCollection.FirstOrDefault(u => u.Id == 1);
u.FirstName = "Bob"
That will modify the real object, as well as:
foreach (User u in UserCollection.Where(u => u.Id > 10)
{
u.Property = SomeValue;
}
With Python 3 I had this problem:
self.path = 'T:\PythonScripts\Projects\Utilities'
produced this error:
self.path = 'T:\PythonScripts\Projects\Utilities'
^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in
position 25-26: truncated \UXXXXXXXX escape
the fix that worked is:
self.path = r'T:\PythonScripts\Projects\Utilities'
It seems the '\U' was producing an error and the 'r' preceding the string turns off the eight-character Unicode escape (for a raw string) which was failing. (This is a bit of an over-simplification, but it works if you don't care about unicode)
Hope this helps someone
This can be done from the command line. This will create a column for your image with a NOT NULL
property.
CREATE TABLE `test`.`pic` (
`idpic` INTEGER UNSIGNED NOT NULL AUTO_INCREMENT,
`caption` VARCHAR(45) NOT NULL,
`img` LONGBLOB NOT NULL,
PRIMARY KEY(`idpic`)
)
TYPE = InnoDB;

To add some clarification and directly address the question above, there are several classes of characters that cause problems for URLs and URIs.
There are some characters that are disallowed and should never appear in a URL/URI, reserved characters (described below), and other characters that may cause problems in some cases, but are marked as "unwise" or "unsafe". Explanations for why the characters are restricted are clearly spelled out in RFC-1738 (URLs) and RFC-2396 (URIs). Note the newer RFC-3986 (update to RFC-1738) defines the construction of what characters are allowed in a given context but the older spec offers a simpler and more general description of which characters are not allowed with the following rules.
Excluded US-ASCII Characters disallowed within the URI syntax:
control = <US-ASCII coded characters 00-1F and 7F hexadecimal>
space = <US-ASCII coded character 20 hexadecimal>
delims = "<" | ">" | "#" | "%" | <">
The character "#" is excluded because it is used to delimit a URI from a fragment identifier. The percent character "%" is excluded because it is used for the encoding of escaped characters. In other words, the "#" and "%" are reserved characters that must be used in a specific context.
List of unwise characters are allowed but may cause problems:
unwise = "{" | "}" | "|" | "\" | "^" | "[" | "]" | "`"
Characters that are reserved within a query component and/or have special meaning within a URI/URL:
reserved = ";" | "/" | "?" | ":" | "@" | "&" | "=" | "+" | "$" | ","
The "reserved" syntax class above refers to those characters that are allowed within a URI, but which may not be allowed within a particular component of the generic URI syntax. Characters in the "reserved" set are not reserved in all contexts. The hostname, for example, can contain an optional username so it could be something like ftp://user@hostname/
where the '@' character has special meaning.
Here is an example of a URL that has invalid and unwise characters (e.g. '$', '[', ']') and should be properly encoded:
http://mw1.google.com/mw-earth-vectordb/kml-samples/gp/seattle/gigapxl/$[level]/r$[y]_c$[x].jpg
Some of the character restrictions for URIs and URLs are programming language-dependent. For example, the '|' (0x7C) character although only marked as "unwise" in the URI spec will throw a URISyntaxException in the Java java.net.URI constructor so a URL like http://api.google.com/q?exp=a|b
is not allowed and must be encoded instead as http://api.google.com/q?exp=a%7Cb
if using Java with a URI object instance.
There are quite a few ways in which you can implement Stacks and Queues in Javascript. Most of the answers above are quite shallow implementations and I would try to implement something more readable (using new syntax features of es6) and robust.
Here's the stack implementation:
class Stack {
constructor(...items){
this._items = []
if(items.length>0)
items.forEach(item => this._items.push(item) )
}
push(...items){
//push item to the stack
items.forEach(item => this._items.push(item) )
return this._items;
}
pop(count=0){
//pull out the topmost item (last item) from stack
if(count===0)
return this._items.pop()
else
return this._items.splice( -count, count )
}
peek(){
// see what's the last item in stack
return this._items[this._items.length-1]
}
size(){
//no. of items in stack
return this._items.length
}
isEmpty(){
// return whether the stack is empty or not
return this._items.length==0
}
toArray(){
return this._items;
}
}
And this is how you can use the stack :
let my_stack = new Stack(1,24,4);
// [1, 24, 4]
my_stack.push(23)
//[1, 24, 4, 23]
my_stack.push(1,2,342);
//[1, 24, 4, 23, 1, 2, 342]
my_stack.pop();
//[1, 24, 4, 23, 1, 2]
my_stack.pop(3)
//[1, 24, 4]
my_stack.isEmpty()
// false
my_stack.size();
//3
If you would like to see the detailed description about this implementation and how it can be further improved, you can read here : http://jschap.com/data-structures-in-javascript-stack/
Here's the code for queue implementation in es6 :
class Queue{
constructor(...items){
//initialize the items in queue
this._items = []
// enqueuing the items passed to the constructor
this.enqueue(...items)
}
enqueue(...items){
//push items into the queue
items.forEach( item => this._items.push(item) )
return this._items;
}
dequeue(count=1){
//pull out the first item from the queue
this._items.splice(0,count);
return this._items;
}
peek(){
//peek at the first item from the queue
return this._items[0]
}
size(){
//get the length of queue
return this._items.length
}
isEmpty(){
//find whether the queue is empty or no
return this._items.length===0
}
}
Here's how you can use this implementation:
let my_queue = new Queue(1,24,4);
// [1, 24, 4]
my_queue.enqueue(23)
//[1, 24, 4, 23]
my_queue.enqueue(1,2,342);
//[1, 24, 4, 23, 1, 2, 342]
my_queue.dequeue();
//[24, 4, 23, 1, 2, 342]
my_queue.dequeue(3)
//[1, 2, 342]
my_queue.isEmpty()
// false
my_queue.size();
//3

If you use numpy.multiply
S = [22, 33, 45.6, 21.6, 51.8]
P = 2.45
multiply(S, P)
It gives you as a result
array([53.9 , 80.85, 111.72, 52.92, 126.91])
This is a summary of a Wikipedia article. It specifies the different types of relationships you can stipulate in PHPmyadmin. I am putting it here because it is relevant to @Nathan's comment on setting the foreign keys options for "on update/delete" but is too large for a comment - hope it helps.
CASCADE
Whenever rows in the master (referenced) table are deleted (resp. updated), the respective rows of the child (referencing) table with a matching foreign key column will get deleted (resp. updated) as well. This is called a cascade delete (resp. update[2]).
RESTRICT
A value cannot be updated or deleted when a row exists in a foreign key table that references the value in the referenced table. Similarly, a row cannot be deleted as long as there is a reference to it from a foreign key table.
NO ACTION
NO ACTION and RESTRICT are very much alike. The main difference between NO ACTION and RESTRICT is that with NO ACTION the referential integrity check is done after trying to alter the table. RESTRICT does the check before trying to execute the UPDATE or DELETE statement. Both referential actions act the same if the referential integrity check fails: the UPDATE or DELETE statement will result in an error.
SET NULL
The foreign key values in the referencing row are set to NULL when the referenced row is updated or deleted. This is only possible if the respective columns in the referencing table are nullable. Due to the semantics of NULL, a referencing row with NULLs in the foreign key columns does not require a referenced row.
SET DEFAULT
Similar to SET NULL, the foreign key values in the referencing row are set to the column default when the referenced row is updated or deleted.
Here is the correct command: set path=%path%;C:\Python34 [Replace with the correct path of your python installation]
I had the same problem and I just solved this like that.
As some other people pointed out, this is volatile configuration, it only works for the current cmd session, and (obviously) you have to set your path before you run npm install.
I hope this helps.

Previous anwser works fine. I would just add that you dont need to specify CURLOPT_POSTFIELDS as "xmlRequest=" . $input_xml
to read your $_POST. You can use file_get_contents('php://input')
to get the raw post data as plain XML.
If you are looking for a library to carry out client-side image compression, you can check this out:compress.js. This will basically help you compress multiple images purely with JavaScript and convert them to base64 string. You can optionally set the maximum size in MB and also the preferred image quality.
To illustrate Nippysaurus's answer: If you are going to add the new items to the list and want to process the newly added items too during the same enumeration then you can just use for loop instead of foreach loop, problem solved :)
var list = new List<YourData>();
... populate the list ...
//foreach (var entryToProcess in list)
for (int i = 0; i < list.Count; i++)
{
var entryToProcess = list[i];
var resultOfProcessing = DoStuffToEntry(entryToProcess);
if (... condition ...)
list.Add(new YourData(...));
}
For runnable example:
void Main()
{
var list = new List<int>();
for (int i = 0; i < 10; i++)
list.Add(i);
//foreach (var entry in list)
for (int i = 0; i < list.Count; i++)
{
var entry = list[i];
if (entry % 2 == 0)
list.Add(entry + 1);
Console.Write(entry + ", ");
}
Console.Write(list);
}
Output of last example:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 1, 3, 5, 7, 9,

To remove the commas, you'll need to use replace
on the string. To convert to a float so you can do the maths, you'll need parseFloat
:
var total = parseFloat('100,000.00'.replace(/,/g, '')) +
parseFloat('500,000.00'.replace(/,/g, ''));
Guido van Rossum (the inventor of Python) answers this exact question himself in an old blog post.
Basically, he admits that it's theoretically possible, but that any proposed solution would be un-Pythonic:
"But the complexity of any proposed solution for this puzzle is immense, to me: it requires the parser (or more precisely, the lexer) to be able to switch back and forth between indent-sensitive and indent-insensitive modes, keeping a stack of previous modes and indentation level. Technically that can all be solved (there's already a stack of indentation levels that could be generalized). But none of that takes away my gut feeling that it is all an elaborate Rube Goldberg contraption."

If you type:
git status
Git will tell you what is staged, etc., including instructions on how to unstage:
use "git reset HEAD <file>..." to unstage
I find Git does a pretty good job of nudging me to do the right thing in situations like this.
Note: Recent Git versions (1.8.4.x) have changed this message:
(use "git rm --cached <file>..." to unstage)

It took a while to put together a solution for this, but have found this is the easiest way to get it to work in the way that you describe. There could be better ways to do this, but since you haven't posted your activity code I will have to improvise and assume you have a list like this at the start of your activity:
private List<String> items = db.getItems();
ExampleActivity.java
private List<String> items;
private Menu menu;
@Override
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.example, menu);
this.menu = menu;
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();
search.setSearchableInfo(manager.getSearchableInfo(getComponentName()));
search.setOnQueryTextListener(new OnQueryTextListener() {
@Override
public boolean onQueryTextChange(String query) {
loadHistory(query);
return true;
}
});
}
return true;
}
// History
@TargetApi(Build.VERSION_CODES.HONEYCOMB)
private void loadHistory(String query) {
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
// Cursor
String[] columns = new String[] { "_id", "text" };
Object[] temp = new Object[] { 0, "default" };
MatrixCursor cursor = new MatrixCursor(columns);
for(int i = 0; i < items.size(); i++) {
temp[0] = i;
temp[1] = items.get(i);
cursor.addRow(temp);
}
// SearchView
SearchManager manager = (SearchManager) getSystemService(Context.SEARCH_SERVICE);
final SearchView search = (SearchView) menu.findItem(R.id.search).getActionView();
search.setSuggestionsAdapter(new ExampleAdapter(this, cursor, items));
}
}
Now you need to create an adapter extended from CursorAdapter
:
ExampleAdapter.java
public class ExampleAdapter extends CursorAdapter {
private List<String> items;
private TextView text;
public ExampleAdapter(Context context, Cursor cursor, List<String> items) {
super(context, cursor, false);
this.items = items;
}
@Override
public void bindView(View view, Context context, Cursor cursor) {
text.setText(items.get(cursor.getPosition()));
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.item, parent, false);
text = (TextView) view.findViewById(R.id.text);
return view;
}
}
A better way to do this is if your list data is from a database, you can pass the Cursor
returned by database functions directly to ExampleAdapter
and use the relevant column selector to display the column text in the TextView
referenced in the adapter.
Please note: when you import CursorAdapter
don't import the Android support version, import the standard android.widget.CursorAdapter
instead.
The adapter will also require a custom layout:
res/layout/item.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="@+id/item"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
You can now customize list items by adding additional text or image views to the layout and populating them with data in the adapter.
This should be all, but if you haven't done this already you need a SearchView menu item:
res/menu/example.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/search"
android:title="@string/search"
android:showAsAction="ifRoom"
android:actionViewClass="android.widget.SearchView" />
</menu>
Then create a searchable configuration:
res/xml/searchable.xml
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="@string/search"
android:hint="@string/search" >
</searchable>
Finally add this inside the relevant activity tag in the manifest file:
AndroidManifest.xml
<intent-filter>
<action android:name="android.intent.action.SEARCH" />
</intent-filter>
<meta-data
android:name="android.app.default_searchable"
android:value="com.example.ExampleActivity" />
<meta-data
android:name="android.app.searchable"
android:resource="@xml/searchable" />
Please note: The @string/search
string used in the examples should be defined in values/strings.xml, also don't forget to update the reference to com.example
for your project.
You need to download the java-openjfx package from the official Arch Linux repos. (Also, make sure you have the openjdk8-openjdk package). After doing that, open your project in Intellij and go to Project-Structure -> SDKs -> 1.8 -> Classpath and try removing the old JDK you had and clicking on the directory for the new JDK that will now contain jfxrt.jar.
Probably the string would be like this data:image/jpeg;base64,/9j/4QN8RXh...
First split for /
and get the second token.
var StrAfterSlash = Face.Split('/')[1];
Then Split for ;
and get the first token which will be the format. In my case it's jpeg.
var ImageFormat =StrAfterSlash.Split(';')[0];
Then remove the line data:image/jpeg;base64,
for the collected format
CleanFaceData=Face.Replace($"data:image/{ImageFormat };base64,",string.Empty);
The notion of complex numbers was introduced in mathematics, from the need of calculating negative quadratic roots. Complex number concept was taken by a variety of engineering fields.
Today that complex numbers are widely used in advanced engineering domains such as physics, electronics, mechanics, astronomy, etc...
Real and imaginary part, of a negative square root example:
#include <stdio.h>
#include <complex.h>
int main()
{
int negNum;
printf("Calculate negative square roots:\n"
"Enter negative number:");
scanf("%d", &negNum);
double complex negSqrt = csqrt(negNum);
double pReal = creal(negSqrt);
double pImag = cimag(negSqrt);
printf("\nReal part %f, imaginary part %f"
", for negative square root.(%d)",
pReal, pImag, negNum);
return 0;
}
This is a shameless plug, but I'm just now writing some extensive Javadoc for JSch.
Also, there is now a Manual in the JSch Wiki (written mainly by me).
About the original question, there is not really an example for handling the streams. Reading/writing a stream is done as always.
But there simply can't be a sure way to know when one command in a shell has finished just from reading the shell's output (this is independent of the SSH protocol).
If the shell is interactive, i.e. it has a terminal attached, it will usually print a prompt, which you could try to recognize. But at least theoretically this prompt string could also occur in normal output from a command. If you want to be sure, open individual exec
channels for each command instead of using a shell channel. The shell channel is mainly used for interactive use by a human user, I think.
Another simple and complete example of turning the recursive function into iterative one using the stack.
#include <iostream>
#include <stack>
using namespace std;
int GCD(int a, int b) { return b == 0 ? a : GCD(b, a % b); }
struct Par
{
int a, b;
Par() : Par(0, 0) {}
Par(int _a, int _b) : a(_a), b(_b) {}
};
int GCDIter(int a, int b)
{
stack<Par> rcstack;
if (b == 0)
return a;
rcstack.push(Par(b, a % b));
Par p;
while (!rcstack.empty())
{
p = rcstack.top();
rcstack.pop();
if (p.b == 0)
continue;
rcstack.push(Par(p.b, p.a % p.b));
}
return p.a;
}
int main()
{
//cout << GCD(24, 36) << endl;
cout << GCDIter(81, 36) << endl;
cin.get();
return 0;
}

I found an alternative that works.
None of these answers worked for me (currently testing in FireFox 22.0), and after a lot of research I found, what seems to be, a much cleaner and straight forward solution.
Implemented solution:
function IsScrollbarAtBottom() {
var documentHeight = $(document).height();
var scrollDifference = $(window).height() + $(window).scrollTop();
return (documentHeight == scrollDifference);
}

No, this is not supported in MySQL stored routine syntax.
Feel free to submit a feature request at bugs.mysql.com.
For beginners, the accepted answer is correct, but a little terse if you're not that familiar with either VSC or Regex.
So, in case this is your first contact with either:
To find and modify text,
In the "Find" step, you can use regex with "capturing groups," e.g. I want to find (group1) and (group2)
, using parentheses. This would find the same text as I want to find group1 and group2
, but with the difference that you can then reference group1
and group2
in the next step:
In the "Replace" step, you can refer to the capturing groups via $1
, $2
etc, so you could change the sentence to I found $1 and $2 having a picnic
, which would output I found group1 and group2 having a picnic.
Notes:
Instead of just a string, anything inside or outside the ()
can be a regular expression.
$0
refers to the whole match
This solution needs the jQuery's data method.
$._data($(".example").get(0), "events")
$._data()
is just accessing jQuery's data method. A more readable alternative could be jQuery._data()
.
Interesting point by this SO answer:
As of jQuery 1.8, the event data is no longer available from the "public API" for data. Read this jQuery blog post. You should now use this instead:
jQuery._data( elem, "events" );
elem should be an HTML Element, not a jQuery object, or selector.Please note, that this is an internal, 'private' structure, and shouldn't be modified. Use this for debugging purposes only.
In older versions of jQuery, you might have to use the old method which is:
jQuery( elem ).data( "events" );
A version agnostic jQuery would be: (jQuery._data || jQuery.data)(elem, 'events');
I had the same problem and the solution was to encapsulate the json inside this function
jsonp(
.... your json ...
)
Database and table names are not case sensitive in Windows, and case sensitive in most varieties of Unix or Linux.
To resolve the issue, set the lower_case_table_names to 1
lower_case_table_names=1
This will make all your tables lowercase, no matter how you write them.

Here is your solution for the problem,
$letter = array();
for ($i = 'A'; $i !== 'ZZ'; $i++){
if(ord($i) % 2 != 0)
$letter[] .= $i;
}
print_r($letter);
You need to get the ASCII value for that character which will solve your problem.
Here is ord doc and working code.
For your requirement, you can do like this,
for ($i = 'A'; $i !== 'ZZ'; ord($i)+$x){
$letter[] .= $i;
}
print_r($letter);
Here set $x as per your requirement.
you have to create a custom DataGridView
`

{
if (PreventUserClick) return;
base.OnMouseDown(e);
}
}
}
` note that you have to first compile the program once with the added class, before you can use the new control.
then go to The .Designer.cs and change the old DataGridView to the new one without having to mess up you previous code.
private System.Windows.Forms.DataGridView dgv; // found close to the bottom

this.dgv = new System.Windows.Forms.DataGridView();

If you want your integers to be bound between two integers (i.e. start with something other than 1), you can use something like this:
with bnd as (select 4 lo, 9 hi from dual)
select (select lo from bnd) - 1 + level r
from dual
connect by level <= (select hi-lo from bnd);
It gives:
4

Using HTTP Request verb such as GET, POST, DELETE, PUT etc... enables you to build RESTful web applications. Read about it here: http://en.wikipedia.org/wiki/Representational_state_transfer
The easiest way to see benefits from this is to look at this example.
Every MVC framework has a Router/Dispatcher
that maps URL-s to actionControllers.
So URL like this: /blog/article/1
would invoke blogController::articleAction($id);
Now this Router is only aware of the URL or /blog/article/1/
But if that Router would be aware of whole HTTP Request object instead of just URL, he could have access HTTP Request verb (GET, POST, PUT, DELETE...), and many other useful stuff about current HTTP Request.
That would enable you to configure application so it can accept the same URL and map it to different actionControllers depending on the HTTP Request verb.
For example:
if you want to retrive article 1 you can do this:
GET /blog/article/1 HTTP/1.1
but if you want to delete article 1 you will do this:
DELETE /blog/article/1 HTTP/1.1
Notice that both HTTP Requests have the same URI, /blog/article/1, the only difference is the HTTP Request verb. And based on that verb your router can call different actionController. This enables you to build neat URL-s.
Read this two articles, they might help you:
These articles are about Symfony 2 framework, but they can help you to figure out how does HTTP Requests and Responses work.
Hope this helps!
Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:
<Style TargetType="{x:Type TabItem}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type TabItem}">
<Grid>
<Border Name="Border" Margin="0,0,0,0" Background="Transparent"
BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
<ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
HorizontalAlignment="Center"

RecognizesAccessKey="True">
<ContentPresenter.LayoutTransform>
<RotateTransform Angle="270" />
</ContentPresenter.LayoutTransform>
</ContentPresenter>
</Border>

On our site we have pages where the content is static, and pages where it is loaded in with AJAX. On one page (a search page), there were cases when the AJAX results would more than fill the page, and cases where it would return no results. In order for the background image to fill the page in all cases we had to apply the following CSS:
html {
margin: 0px;
height: 100%;
width: 100%;
}
body {
margin: 0px;
min-height: 100%;
width: 100%;
}
height
for the html
and min-height
for the body
.
you cannot access array (php array) from js try
<?php
$array = array(1,2,3,4,5,6);
echo implode('~',$array);
?>
and js
$(document).ready( function() {
$('#prev').click(function() {
$.ajax({
type: 'POST',
url: 'ajax.php',
data: 'id=testdata',
cache: false,
success: function(data) {
result=data.split('~');
$('#content1').html(result[0]);
},
});
});
});
Well, Pavel was close, but there's even a more simple and elegant solution to initialize a sequential container from a c style array.
In your case:
w_ (array, std::end(array))
For Passing a single variable to view.
Inside Your controller create a method like:
function sleep()
{
return view('welcome')->with('title','My App');
}
In Your route
Route::get('/sleep', 'TestController@sleep');
In Your View Welcome.blade.php
. You can echo your variable like {{ $title }}
For An Array(multiple values) change,sleep method to :
function sleep()
{
$data = array(
'title'=>'My App',
'Description'=>'This is New Application',
'author'=>'foo'
);
return view('welcome')->with($data);
}
You can access you variable like {{ $author }}
.
An alternative way to order a List is using the Collections framework;
in this case using the SortedSet (the bean in the list should implement Comparable, so Double is ok):
List<Double> testList;
...
SortedSet<Double> sortedSet= new TreeSet<Double>();
for(Double number: testList) {
sortedSet.add(number);
}
orderedList=new ArrayList(sortedSet);
In general, to order by an attribute of a bean in the list,put all the elements of the list in a SortedMap, using as a key the attribute, then get the values() from the SortedMap (the attribute should implement Comparable):
List<Bean> testList;
...
SortedMap<AttributeType,Bean> sortedMap= new TreeMap<AttributeType, Bean>();
for(Bean bean : testList) {
sortedMap.put(bean.getAttribute(),bean);
}
orderedList=new ArrayList(sortedMap.values());
I think the best way to reach your div:
var your_element=$('iframe#uploads').children('iframe').children('div#element');
It should work well.
This can be simplified by completely skipping the where object and the $users declaration. All you need is:
Code
get-content c:\scripts\users.txt | get-aduser -properties * | select displayname, office | export-csv c:\path\to\your.csv
For the second part of your question, see the array page of the manual, which states (quoting) :
Array assignment always involves value copying. Use the reference operator to copy an array by reference.
And the given example :
<?php
$arr1 = array(2, 3);
$arr2 = $arr1;
$arr2[] = 4; // $arr2 is changed,
// $arr1 is still array(2, 3)
$arr3 = &$arr1;
$arr3[] = 4; // now $arr1 and $arr3 are the same
?>
For the first part, the best way to be sure is to try ;-)
Consider this example of code :
function my_func($a) {
$a[] = 30;
}
$arr = array(10, 20);
my_func($arr);
var_dump($arr);
It'll give this output :
array
0 => int 10
1 => int 20
Which indicates the function has not modified the "outside" array that was passed as a parameter : it's passed as a copy, and not a reference.
If you want it passed by reference, you'll have to modify the function, this way :
function my_func(& $a) {
$a[] = 30;
}
And the output will become :
array
0 => int 10
1 => int 20
2 => int 30
As, this time, the array has been passed "by reference".
Don't hesitate to read the References Explained section of the manual : it should answer some of your questions ;-)
Have just solved. Just two f. days of brutforce
For me the secret was in following:
I called POST /api/auth and see that cookies were successfully received.
Then calling GET /api/users/ with credentials: 'include'
and got 401 unauth, because of no cookies were sent with the request.
The KEY is to set credentials: 'include'
for the first /api/auth
call too.
You can also use list comprehension on splitted string
[ int(x) for x in example_string.split(',') ]
Some others not mentioned here -
Mono Cecil: With Cecil, you can load existing managed assemblies, browse all the contained types, modify them on the fly and save back to the disk the modified assembly.
Kaliro: This is a tool for exploring the content of applications built using the Microsoft.Net framework.
Dotnet IL Editor (DILE): Dotnet IL Editor (DILE) allows disassembling and debugging .NET 1.0/1.1/2.0/3.0/3.5 applications without source code or .pdb files. It can debug even itself or the assemblies of the .NET Framework on IL level.
Common Compiler Infrastructure: Microsoft Research Common Compiler Infrastructure (CCI) is a set of libraries and an application programming interface (API) that supports some of the functionality that is common to compilers and related programming tools. CCI is used primarily by applications that create, modify or analyze .NET portable executable (PE) and debug (PDB) files.
In my case, my Android app uses Volley to make a POST call with an empty body to an API application hosted on Microsoft Azure.
The error was:
JSONException: Value <p>iisnode of type java.lang.String cannot be converted to JSONObject
This is a snippet on how I was constructing the Volley JSON request:
final JSONObject emptyJsonObject = new JSONObject();
JsonObjectRequest request = new JsonObjectRequest(Request.Method.POST, url, emptyJsonObject, listener, errorListener);
I solved my problem by creating the JSONObject
with an empty JSON object as follows:
final JSONObject emptyJsonObject = new JSONObject("{}");
My solution is along the lines to this older answer.
$('tableName').find('tr').length
Use command >> file_to_append_to
to append to a file.
For example echo "Hello" >> testFile.txt
CAUTION: if you only use a single >
you will overwrite the contents of the file. To ensure that doesn't ever happen, you can add set -o noclobber
to your .bashrc
.
This ensures that if you accidentally type command > file_to_append_to
to an existing file, it will alert you that the file exists already. Sample error message: file exists: testFile.txt
Thus, when you use >
it will only allow you to create a new file, not overwrite an existing file.
Tried and working. you are using,
<textarea name='Status'> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>
I am using javascript , (don't know about php), use id ="status" in textarea like
<textarea name='Status' id="status"> </textarea>
<input type='button' onclick='UpdateStatus()' value='Status Update'>
then make a call to servlet sending the status to backend for updating using whatever strutucre(like MVC in java or anyother) you like, like this in your UI in script tag
<srcipt>
function UpdateStatus(){
//make an ajax call and get status value using the same 'id'
var var1= document.getElementById("status").value;
$.ajax({
type:"GET",//or POST
url:'http://localhost:7080/ajaxforjson/Testajax',
// (or whatever your url is)
data:{data1:var1},
//can send multipledata like {data1:var1,data2:var2,data3:var3
//can use dataType:'text/html' or 'json' if response type expected
success:function(responsedata){
// process on data
alert("got response as "+"'"+responsedata+"'");
}
})
}
</script>
and jsp is like
the servlet will look like: //webservlet("/zcvdzv") is just for url annotation
@WebServlet("/Testajax")
public class Testajax extends HttpServlet {
private static final long serialVersionUID = 1L;
public Testajax() {
super();
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
String data1=request.getParameter("data1");
//do processing on datas pass in other java class to add to DB
// i am adding or concatenate
String data="i Got : "+"'"+data1+"' ";
System.out.println(" data1 : "+data1+"\n data "+data);
response.getWriter().write(data);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
doGet(request, response);
}
}
You can do it like this:
// step 1
var one = "1" + "2" + "3"; // string value "123"
// step 2
var two = parseInt(one); // integer value 123
// step 3
var three = 123 + 100; // integer value 223
// step 4
var four = three.toString(); // string value "223"
This indicates the linux has delivered a SIGTERM
to your process. This is usually at the request of some other process (via kill()
) but could also be sent by your process to itself (using raise()
). This signal requests an orderly shutdown of your process.
If you need a quick cheatsheet of signal numbers, open a bash shell and:
$ kill -l
1) SIGHUP 2) SIGINT 3) SIGQUIT 4) SIGILL
5) SIGTRAP 6) SIGABRT 7) SIGBUS 8) SIGFPE
9) SIGKILL 10) SIGUSR1 11) SIGSEGV 12) SIGUSR2
13) SIGPIPE 14) SIGALRM 15) SIGTERM 16) SIGSTKFLT
17) SIGCHLD 18) SIGCONT 19) SIGSTOP 20) SIGTSTP
21) SIGTTIN 22) SIGTTOU 23) SIGURG 24) SIGXCPU
25) SIGXFSZ 26) SIGVTALRM 27) SIGPROF 28) SIGWINCH
29) SIGIO 30) SIGPWR 31) SIGSYS 34) SIGRTMIN
35) SIGRTMIN+1 36) SIGRTMIN+2 37) SIGRTMIN+3 38) SIGRTMIN+4
39) SIGRTMIN+5 40) SIGRTMIN+6 41) SIGRTMIN+7 42) SIGRTMIN+8
43) SIGRTMIN+9 44) SIGRTMIN+10 45) SIGRTMIN+11 46) SIGRTMIN+12
47) SIGRTMIN+13 48) SIGRTMIN+14 49) SIGRTMIN+15 50) SIGRTMAX-14
51) SIGRTMAX-13 52) SIGRTMAX-12 53) SIGRTMAX-11 54) SIGRTMAX-10
55) SIGRTMAX-9 56) SIGRTMAX-8 57) SIGRTMAX-7 58) SIGRTMAX-6
59) SIGRTMAX-5 60) SIGRTMAX-4 61) SIGRTMAX-3 62) SIGRTMAX-2
63) SIGRTMAX-1 64) SIGRTMAX
You can determine the sender by using an appropriate signal handler like:
#include <signal.h>
#include <stdio.h>
#include <stdlib.h>
void sigterm_handler(int signal, siginfo_t *info, void *_unused)
{
fprintf(stderr, "Received SIGTERM from process with pid = %u\n",
info->si_pid);
exit(0);
}
int main (void)
{
struct sigaction action = {
.sa_handler = NULL,
.sa_sigaction = sigterm_handler,
.sa_mask = 0,
.sa_flags = SA_SIGINFO,
.sa_restorer = NULL
};
sigaction(SIGTERM, &action, NULL);
sleep(60);
return 0;
}
Notice that the signal handler also includes a call to exit()
. It's also possible for your program to continue to execute by ignoring the signal, but this isn't recommended in general (if it's a user doing it there's a good chance it will be followed by a SIGKILL if your process doesn't exit, and you lost your opportunity to do any cleanup then).
We can use date -d option
1) Change format to "%Y-%m-%d" format i.e 20121212 to 2012-12-12
date -d '20121212' +'%Y-%m-%d'
2)Get next or last day from a given date=20121212. Like get a date 7 days in past with specific format
date -d '20121212 -7 days' +'%Y-%m-%d'
3) If we are getting date in some variable say dat
dat2=$(date -d "$dat -1 days" +'%Y%m%d')

I solved my issue on Bing Maps WPF on my project Using CalculateRoute (). The solution in my case was setting the maxReceivedMessageSize and maxReceivedMessageSize on attribute "httpTransport" for "customBinding" section .

Current answers are perfectly correct on how to create the aggregations, but none actually address the column alias/renaming that is also requested in the question.
Typically, this is how I handle this case:
val dimensionFields = List("col1")
val metrics = List("col2", "col3", "col4")
val columnOfInterests = dimensions ++ metrics
val df = spark.read.table("some_table").
.select(columnOfInterests.map(c => col(c)):_*)
.groupBy(dimensions.map(d => col(d)): _*)
.agg(metrics.map( m => m -> "sum").toMap)
.toDF(columnOfInterests:_*) // that's the interesting part
The last line essentially renames every columns of the aggregated dataframe to the original fields, essentially changing sum(col2)
and sum(col3)
to simply col2
and col3
.
You just need to specify a minimum date - setting it to 0 means that the minimum date is 0 days from today i.e. today. You could pass the string '0d'
instead (the default unit is days).
$(function () {
$('#date').datepicker({ minDate: 0 });
});
I found the log file at /usr/local/var/log/postgres.log on a mac installation from brew.
You can increase the performance of excel export by following these steps:
1) When you fetch data from database, avoid casting the result set to the list of entity classes. Instead assign it directly to List
List<Object[]> resultList =session.createSQLQuery("SELECT t1.employee_name, t1.employee_id ... from t_employee t1 ").list();
instead of
List<Employee> employeeList =session.createSQLQuery("SELECT t1.employee_name, t1.employee_id ... from t_employee t1 ").list();
2) Create excel workbook object using SXSSFWorkbook instead of XSSFWorkbook and create new row using SXSSFRow when the data is not empty.
3) Use java.util.Iterator to iterate the data list.
Iterator itr = resultList.iterator();
4) Write data into excel using column++.
int rowCount = 0;
int column = 0;
while(itr.hasNext()){
SXSSFRow row = xssfSheet.createRow(rowCount++);
Object[] object = (Object[]) itr.next();
//column 1
row.setCellValue(object[column++]); // write logic to create cell with required style in setCellValue method
//column 2
row.setCellValue(object[column++]);
itr.remove();
}
5) While iterating the list, write the data into excel sheet and remove the row from list using remove method. This is to avoid holding unwanted data from the list and clear the java heap size.
itr.remove();
Multiline version (e.g. if you need to add comment after each line):
a = if b # a depends on b
then 5 # b is true
else 10 # b is false

You could also just copy plugins to the eclipse/plugins

I have found solution at https://www.youtube.com/watch?v=dm4z9l26O0I
You would need to use Tools > Script Editor. Create .gs and .html files there. See example at http://goo.gl/LxGXfU (link can be also found under Youtube video). Just copy
Once you have .gs and .html files in place save them and reload your spreadsheet. You will see "Custom menu" as the last item of your top menu. Select cell you would like to manage and click on this menu item.
During the first time it will ask you to authorize application - go ahead and do this.
Note (1): make sure that your cell has "Data validation" defined before you click on "Custom menu".
Note (2): it appeared that solution works with "List from a range" criteria for Data validation (it does not work with "List of items")
I actually came across something like this not too long ago... check it out over on msdn (see the first answer)
in summary:
.cer - certificate stored in the X.509 standard format. This certificate contains information about the certificate's owner... along with public and private keys.
.pvk - files are used to store private keys for code signing. You can also create a certificate based on .pvk private key file.
.pfx - stands for personal exchange format. It is used to exchange public and private objects in a single file. A pfx file can be created from .cer file. Can also be used to create a Software Publisher Certificate.
I summarized the info from the page based on the suggestion from the comments.
You need first to cut the string in how many pieces you want. Then replace the part that you want:
$text = 'this is the test for string.';
$text = substr($text, 0, 10);
echo $text = str_replace(" ", "_", $text);
This will output:

first of all;
a Fragment
must be inside a FragmentActivity
, that's the first rule,
a FragmentActivity
is quite similar to a standart Activity
that you already know, besides having some Fragment oriented methods
second thing about Fragments, is that there is one important method you MUST call, wich is onCreateView
, where you inflate your layout, think of it as the setContentLayout
here is an example:
@Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { mView = inflater.inflate(R.layout.fragment_layout, container, false); return mView; }
and continu your work based on that mView, so to find a View
by id, call mView.findViewById(..);
for the FragmentActivity
part:
the xml part "must" have a FrameLayout
in order to inflate a fragment in it
<FrameLayout android:id="@+id/content_frame" android:layout_width="match_parent" android:layout_height="match_parent" > </FrameLayout>
as for the inflation part
getSupportFragmentManager().beginTransaction().replace(R.id.content_frame, new YOUR_FRAGMENT, "TAG").commit();
begin with these, as there is tons of other stuf you must know about fragments and fragment activities, start of by reading something about it (like life cycle) at the android developer site
Windows version:
cd \Program Files\NVIDIA Corporation\NVSMI
nvidia-smi
JsonNode node = mapper.readValue("[{\"id\":\"value11\",\"name\": \"value12\",\"qty\":\"value13\"},"
System.out.println("id : "+node.findValues("id").get(0).asText());
this also done the trick.
Just need to get the element and use the method setCustomValidity.
Example
var foo = document.getElementById('foo');
foo.setCustomValidity(' An error occurred');
If you don't care about any local changes (including untracked or generated files or subrepositories which just happen to be here) and just want a copy from the repo:
git reset --hard HEAD
git clean -xffd
git pull
Again, this will nuke any changes you've made locally so use carefully. Think about rm -Rf
when doing this.
Another thing to mention is that atan2
is more stable when computing tangents using an expression like atan(y / x)
and x
is 0 or close to 0.
Page Control can be contained in Window Control but vice versa is not possible
You can use Page control within the Window control using NavigationWindow and Frame controls. Window is the root control that must be used to hold/host other controls (e.g. Button) as container. Page is a control which can be hosted in other container controls like NavigationWindow or Frame. Page control has its own goal to serve like other controls (e.g. Button). Page is to create browser like applications. So if you host Page in NavigationWindow, you will get the navigation implementation built-in. Pages are intended for use in Navigation applications (usually with Back and Forward buttons, e.g. Internet Explorer).
WPF provides support for browser style navigation inside standalone application using Page class. User can create multiple pages, navigate between those pages along with data.There are multiple ways available to Navigate through one page to another page.
Here are a variety of ways to do this in base R
including an alternative aggregate
approach. The examples below return means per month, which I think is what you requested. Although, the same approach could be used to return means per person:
Using ave
:
my.data <- read.table(text = '
Name Month Rate1 Rate2
Aira 1 12 23
Aira 2 18 73
Aira 3 19 45
Ben 1 53 19
Ben 2 22 87
Ben 3 19 45
Cat 1 22 87
Cat 2 67 43
Cat 3 45 32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')
Rate1.mean <- with(my.data, ave(Rate1, Month, FUN = function(x) mean(x, na.rm = TRUE)))
Rate2.mean <- with(my.data, ave(Rate2, Month, FUN = function(x) mean(x, na.rm = TRUE)))
my.data <- data.frame(my.data, Rate1.mean, Rate2.mean)
my.data
Using by
:
my.data <- read.table(text = '
Name Month Rate1 Rate2
Aira 1 12 23
Aira 2 18 73
Aira 3 19 45
Ben 1 53 19
Ben 2 22 87
Ben 3 19 45
Cat 1 22 87
Cat 2 67 43
Cat 3 45 32
', header = TRUE, stringsAsFactors = FALSE, na.strings = 'NA')
by.month <- as.data.frame(do.call("rbind", by(my.data, my.data$Month, FUN = function(x) colMeans(x[,3:4]))))
colnames(by.month) <- c('Rate1.mean', 'Rate2.mean')
by.month <- cbind(Month = rownames(by.month), by.month)
my.data <- merge(my.data, by.month, by = 'Month')
my.data
Using lapply
and split
:

LastLogon is the last time that the user logged into whichever domain controller you happen to have been load balanced to at the moment that you ran the GET-ADUser cmdlet, and is not replicated across the domain. You really should use LastLogonTimestamp if you want the time the last user logged in to any domain controller in your domain.
Ctrl+p is the normal alternative to the up arrow. Make sure you have gnu readline enabled in your Python build.
You first have to tell Gnuplot to use a style that uses points, e.g. with points
or with linespoints
. Try for example:
plot sin(x) with points
Output:
Now try:
plot sin(x) with points pointtype 5
Output:
You may also want to look at the output from the test

With bash:
Create an array of entries with ( ) and get the count with #.
FILES=(./*); echo ${#FILES[@]}
Ok that doesn't recursively count files but I wanted to show the simple option first. A common use case might be for creating rollover backups of a file. This will create logfile.1, logfile.2, logfile.3 etc.
CNT=(./logfile*); mv logfile logfile.${#CNT[@]}
Recursive count with bash 4+ globstar
enabled (as mentioned by @tripleee)
FILES=(**/*); echo ${#FILES[@]}
To get the count of files recursively we can still use find in the same way.
FILES=(`find . -type f`); echo ${#FILES[@]}
Good part of accepted answer, modified to use UriBuilder.Uri.ParseQueryString() instead of HttpUtility.ParseQueryString():
var builder = new UriBuilder("http://example.com");
var query = builder.Uri.ParseQueryString();
query["foo"] = "bar<>&-baz";
query["bar"] = "bazinga";
builder.Query = query.ToString();
string url = builder.ToString();
A better answer is to leave your script as it was. When doing the Select name
, follow it by -ExpandProperty Name
like so:
Get-ADGroupMember 'Domain Admins' | Select Name -ExpandProperty Name | out-file Admins.txt
UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')
WHERE number like 'KIT%'
or simply this if you are sure that you have no values like this CKIT002
UPDATE tblKit
SET number = REPLACE(number, 'KIT', 'CH')
You have a view model to which your view is strongly typed => use strongly typed helpers:
<%= Html.DropDownListFor(
x => x.SelectedAccountId,
new SelectList(Model.Accounts, "Value", "Text")
) %>
Also notice that I use a SelectList
for the second argument.
And in your controller action you were returning the view model passed as argument and not the one you constructed inside the action which had the Accounts property correctly setup so this could be problematic. I've cleaned it a bit:
public ActionResult AccountTransaction()
{
var accounts = Services.AccountServices.GetAccounts(false);
var viewModel = new AccountTransactionView
{
Accounts = accounts.Select(a => new SelectListItem
{
Text = a.Description,
Value = a.AccountId.ToString()
})
};
return View(viewModel);
}

Official standard dialogs are coming to JavaFX in release 8u40, as part of the implemenation of RT-12643. These should be available in final release form around March of 2015 and in source code form in the JavaFX development repository now.
In the meantime, you can use the ControlsFX solution below...
ControlsFX is the defacto standard 3rd party library for common dialog support in JavaFX (error, warning, confirmation, etc).
There are numerous other 3rd party libraries available which provide common dialog support as pointed out in some other answers and you can create your own dialogs easily enough using the sample code in Sergey's answer.
However, I believe that ControlsFX easily provide the best quality standard JavaFX dialogs available at the moment. Here are some samples from the ControlsFX documentation.
From in Sql Server Management Studio: Tools -> Sql Server profiler. Although as @bobs said, you may need to install additional components first.
Apply the reverse function to the range to iterate backwards:
For Swift 1.2 and earlier:
// Print 10 through 1
for i in reverse(1...10) {
println(i)
}
It also works with half-open ranges:
// Print 9 through 1
for i in reverse(1..<10) {
println(i)
}
Note: reverse(1...10)
creates an array of type [Int]
, so while this might be fine for small ranges, it would be wise to use lazy
as shown below or consider the accepted stride
answer if your range is large.
To avoid creating a large array, use lazy
along with reverse()
. The following test runs efficiently in a Playground showing it is not creating an array with one trillion Int
s!
Test:
var count = 0
for i in lazy(1...1_000_000_000_000).reverse() {
if ++count > 5 {
break
}
println(i)
}
For Swift 2.0 in Xcode 7:
for i in (1...10).reverse() {
print(i)
}
Note that in Swift 2.0, (1...1_000_000_000_000).reverse()
is of type ReverseRandomAccessCollection<(Range<Int>)>
, so this works fine:
var count = 0
for i in (1...1_000_000_000_000).reverse() {
count += 1
if count > 5 {
break
}
print(i)
}
For Swift 3.0 reverse()
has been renamed to reversed()
:
for i in (1...10).reversed() {
print(i) // prints 10 through 1
}
For PyCharm Community Edition 2016.3.2 it is:
"Project Interpreter" -> Top right settings icon -> "More".
Then on the right side there should be a packages icon. When hovering over it it should say "Show paths for selected interpreter". Click it.
Then click the "Add" button or press "alt+insert" to add a new path.
I written in main activity like this,
override fun onSupportNavigateUp(): Boolean {
return findNavController(R.id.my_nav_host_fragment).navigateUp(appBarConfiguration)
}
$ git rev-parse HEAD 273cf91b4057366a560b9ddcee8fe58d4c21e6cb
Update:
Alternatively (if you have tags):
(Good for naming a version, not very good for passing back to git.)
$ git describe v0.1.49-localhost-ag-1-g273cf91
Or (as Mark suggested, listing here for completeness):
$ git show --oneline -s c0235b7 Autorotate uploaded images based on EXIF orientation
The easiest is:
int label = 0;
loop:while(true) {
switch(state) {
case 0:
// Some code
state = 5;
break;
case 2:
// Some code
state = 4;
break;
...
default:
break loop;
}
}
According to my knowledge we should use ng-change with the select option and in textbox case we should use ng-blur.
Bootstrap 4 is not yet a mature tool yet. The part of requiring another plugin to work is even more complicated especially for developers who have been using Bootstrap for a while. I have seen many ways to eliminate the error but not all work for everyone. I think the best and cleanest way to work with Bootstrap 4. Among the Bootstrap installation files, There is one with the name "bootstrap.bundle.js" that already comes with the Popper included.
If you have rooted your phone, but so not have busybox, only stock toybox, here a one-liner to run as root :
mount -o rw,remount $( mount | sed '/ /system /!d' | cut -d " " -f 1 ) /system
toybox do not support the "-o remount,rw" option
if you have busybox, you can use it :
busybox mount -o remount,rw /system
in my case adding clipToPadding
solved the problem.
<android.support.v4.view.ViewPager
...
android:clipToPadding="false"
...
/>

As @MilacH pointed out, there is an error in the implementation. If an statusCode > 400 is returned a IOException is thrown, as the errorHandler is not invoked, from interceptors. The exception can be ignored and is then caught again in the handler method.

The max length of a varchar is subject to the max row size in MySQL, which is 64KB (not counting BLOBs):
VARCHAR(65535)
However, note that the limit is lower if you use a multi-byte character set:
VARCHAR(21844) CHARACTER SET utf8
Here are some examples:
The maximum row size is 65535, but a varchar also includes a byte or two to encode the length of a given string. So you actually can't declare a varchar of the maximum row size, even if it's the only column in the table.
mysql> CREATE TABLE foo ( v VARCHAR(65534) );
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs
But if we try decreasing lengths, we find the greatest length that works:
mysql> CREATE TABLE foo ( v VARCHAR(65532) );
Query OK, 0 rows affected (0.01 sec)
Now if we try to use a multibyte charset at the table level, we find that it counts each character as multiple bytes. UTF8 strings don't necessarily use multiple bytes per string, but MySQL can't assume you'll restrict all your future inserts to single-byte characters.
mysql> CREATE TABLE foo ( v VARCHAR(65532) ) CHARSET=utf8;
ERROR 1074 (42000): Column length too big for column 'v' (max = 21845); use BLOB or TEXT instead
In spite of what the last error told us, InnoDB still doesn't like a length of 21845.
mysql> CREATE TABLE foo ( v VARCHAR(21845) ) CHARSET=utf8;
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs
This makes perfect sense, if you calculate that 21845*3 = 65535, which wouldn't have worked anyway. Whereas 21844*3 = 65532, which does work.
mysql> CREATE TABLE foo ( v VARCHAR(21844) ) CHARSET=utf8;
Query OK, 0 rows affected (0.32 sec)
Try just --with-curl, without specifying a location, and see if it'll find it by itself.
If a function does not return anything, e.g.:
def test():
pass
it has an implicit return value of None
.
Thus, as your pick*
methods do not return anything, e.g.:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
the lines that call them, e.g.:
word = pickEasy()
set word
to None
, so wordInput
in getInput
is None
. This means that:
if guess in wordInput:
is the equivalent of:
if guess in None:
and None
is an instance of NoneType
which does not provide iterator/iteration functionality, so you get that type error.
The fix is to add the return type:
def pickEasy():
word = random.choice(easyWords)
word = str(word)
for i in range(1, len(word) + 1):
wordCount.append("_")
return word
try this. it works for me.
app.configure(function(){
.....
// disable layout
app.set("view options", {layout: false});
// make a custom html template
app.register('.html', {
compile: function(str, options){
return function(locals){
return str;
};
}
});
});
....
app.get('/', function(req, res){
res.render("index.html");
});
Another way to make column aligned is as follows:
using namespace std;
cout.width(20); cout << left << "Artist";
cout.width(20); cout << left << "Title";
cout.width(10); cout << left << "Price";
...
cout.width(20); cout << left << artist;
cout.width(20); cout << left << title;
cout.width(10); cout << left << price;
We should estimate maximum length of values for each column. In this case, values of "Artist" column should not exceed 20 characters and so on.
For anybody else looking, here is a decent set of steps. http://forums.asp.net/t/1678976.aspx/1
Don't forget to manually add your key in OnActionExecuting() like I did.
The way to dynamically modify a CSS property value in a CSS class is by using a CSS variable in the CSS class property value, and then use JavaScript and the DOM to change the CSS variable. The end result is that the styling on the device screen will immediately change when the code runs that sets the new CSS variable value. So, code changes the CSS variable, and the CSS variable is used in the CSS class setting. Note that a CSS class name and a JavaScript Class are two different things.
<style>
:root { /* Set CSS variable values - These values can be changed with JavaScript
and DOM */
--myCSS_ValueOne: initialValue;
}
.classNameHere {
property_Name_Here: var(--myCSS_ValueOne);/* This CSS property gets its value from
the CSS variable */
}
</style>
JavaScript and DOM
<script>
var r = document.querySelector(':root');//Get global root element
function setA_NewCSS_VariableValue() {
r.style.setProperty('--myCSS_ValueOne', 'the_New_Value');// Set a new CSS variable
//value which immediately changes the CSS class setting because the CSS
//property setting uses a CSS Variable -
}
</script>
It is also possible to run a function in response to media queries (changes in the device viewport - like width of the device screen) using the matchMedia()
method.
var x = window.matchMedia("(max-width: 300px)")
x.addListener(setA_NewCSS_VariableValue) // create a listener function that runs
//when the viewport is less than, or equal to, 300 pixels wide.
I got the same problem when toggling the accordion. But when I try to put the script block in the header block, it works for my case!!
<head>
...
<link rel="stylesheet" href="../assets/css/bootstrap.css" />
<script src="../assets/js/jquery-1.9.1.min.js" ></script>

</head>
I'm pretty darn sure I just solved this with:
overflow-y: auto;
(Presumably just overflow: auto;
would work too depending on your needs.)
AFAIK, {...}
can only be used as a path, not inside a query-param. Try this instead:
public interface FooService {
@GET("/maps/api/geocode/json?sensor=false")
void getPositionByZip(@Query("address") String address, Callback<String> cb);
}
If you have an unknown amount of parameters to pass, you can use do something like this:
public interface FooService {
@GET("/maps/api/geocode/json")
@FormUrlEncoded
void getPositionByZip(@FieldMap Map<String, String> params, Callback<String> cb);
}
I was searching an answer for this same question and found ENTRYPOINT in Dockerfile solution for me.
Dockerfile
...
ENTRYPOINT /my-script.sh ; /my-script2.sh ; /bin/bash
Now the scripts are executed when I start the container and I get the bash prompt after the scripts has been executed.

Just use this js file. (I mentioned 2 examples with different js files. hope the second one is what you need) You can simply change the scroll amount, speed etc by changing the parameters.

Here's a Demo
The other answers all mention text-decoration. Sometimes you use a Wordpress theme or someone else's CSS where links are underlined by other methods, so that text-decoration: none won't turn off the underlining.
Border and box-shadow are two other methods I'm aware of for underlining links. To turn these off:
border: none;
and
box-shadow: none;
May I suggest a somewhat hacky but still genius solution! I got the idea from this article and adapted it for Android. Basically you use a WebView
and insert the HTML you want to show and edit in an editable div tag. This way when the user taps the WebView
the keyboard appears and allows editing. They you just add some JavaScript to get back the edited HTML and voila!
Here is the code:
public class HtmlTextEditor extends WebView {
class JsObject {
// This field always keeps the latest edited text
public String text;
@JavascriptInterface
public void textDidChange(String newText) {
text = newText.replace("\n", "");
}
}
private JsObject mJsObject;
public HtmlTextEditor(Context context, AttributeSet attrs) {
super(context, attrs);
getSettings().setJavaScriptEnabled(true);
mJsObject = new JsObject();
addJavascriptInterface(mJsObject, "injectedObject");
setWebViewClient(new WebViewClient(){
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
loadUrl(
"javascript:(function() { " +
" var editor = document.getElementById(\"editor\");" +
" editor.addEventListener(\"input\", function() {" +
" injectedObject.textDidChange(editor.innerHTML);" +
" }, false)" +
"})()");
}
});
}
public void setText(String text) {
if (text == null) { text = ""; }
String editableHtmlTemplate = "<!DOCTYPE html>" + "<html>" + "<head>" + "<meta name=\"viewport\" content=\"initial-scale=1.0\" />" + "</head>" + "<body>" + "<div id=\"editor\" contenteditable=\"true\">___REPLACE___</div>" + "</body>" + "</html>";
String editableHtml = editableHtmlTemplate.replace("___REPLACE___", text);
loadData(editableHtml, "text/html; charset=utf-8", "UTF-8");
// Init the text field in case it's read without editing the text before
mJsObject.text = text;
}
public String getText() {
return mJsObject.text;
}
}
And here is the component as a Gist.
Note: I didn't need the height change callback from the original solution so that's missing here but you can easily add it if needed.
Have the best of both worlds
These days you can just write all your sql statements in lowercase and if you ever need to have it formatted then just install a plugin that will do it for you. This is only applicable if your code editor has those plugins available. VSCode has many extensions that can do this.

It's a simple Mistake while adding a new file you just have to make sure that \
is added to the file before and the new file remain as it is
eg.
Check Out what to do if i want to add a new file named customer.cc
In addition to existing answers it is often desired to format the REST output (typically JSON and XML lacks indentation). Try this:
$ curl https://api.twitter.com/1/help/configuration.xml | xmllint --format -
$ curl https://api.twitter.com/1/help/configuration.json | python -mjson.tool
Tested on Ubuntu 11.0.4/11.10.
Another issue is the desired content type. Twitter uses .xml
/.json
extension, but more idiomatic REST would require Accept
header:
$ curl -H "Accept: application/json"

Just FYI, Geocoder is asynchronous so the accepted answer while logical doesn't really work in this instance. I would prefer to have an outside object that acts as your updater.
var updater = {};
function geoCodeCity(goocoord) {
var geocoder = new google.maps.Geocoder();
geocoder.geocode({
'latLng': goocoord
}, function(results, status) {
if (status == google.maps.GeocoderStatus.OK) {
updater.currentLocation = results[1].formatted_address;
} else {
if (status == "ERROR") {
console.log(status);
}
}
});
};
For performing Unmarshall using JAXB:
1) Convert given XML to XSD(by yourself or by online convertor),
2) Create a JAXB project in eclipse,
3) Create XSD file and paste that converted XSD content in it,
4) Right click on **XSD file--> Generate--> JAXB Classes-->follow the instructions(this will create all nessasary .java files in src, i.e., one package-info, object factory and pojo class),
5) Create another .java file in src to operate unmarshall operation, and run it.
Happy Coding !!
Make sure /webapps/ROOT file is there and it has all the icons, WEB-INF, and index.jsp is in the folder.
When you startup Tomcat, it will run this code in <Tomcat-Directory>/conf/web.xml
directory:
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
The location of index.jsp is in <Tomcat-Directory>/webapps/ROOT/index.jsp
Also, try running tomcat from the /bin directory using ./catalina.sh start
instead of ./startup.sh
. For some reason, ./startup.sh
isn't as reliable.
With flexbox, creating gutters is a pain, especially when wrapping is involved.
You need to use negative margins (as shown in the question):
#box {
display: flex;
width: 100px;
margin: 0 -5px;
}
... or alter the HTML (as shown in another answer):
<div class='flex-wrapper'>
<div class='flex'>
<div class='box'></div>
<div class='box'></div>
...
</div>
</div>
... or something else.
In any case, you need an ugly hack to make it work because flexbox doesn't provide a "flex-gap
" feature
(at least for now).
The issue of gutters, however, is simple and easy with CSS Grid Layout.
The Grid spec provides properties that create space between grid items, while ignoring the space between items and the container. These properties are:
grid-column-gap
grid-row-gap
grid-gap
(the shorthand for both properties above)Recently, the spec has been updated to conform with the CSS Box Alignment Module, which provides a set of alignment properties for use across all box models. So the properties are now:
column-gap
row-gap
gap
(shorthand)However, not all Grid-supporting browsers support the newer properties, so I'll use the original versions in the demo below.
Also, if spacing is needed between items and the container, padding
on the container works just fine (see the third example in the demo below).
From the spec:
10.1. Gutters: the
row-gap
,column-gap
, andgap
propertiesThe
row-gap
andcolumn-gap
properties (and theirgap
shorthand), when specified on a grid container, define the gutters between grid rows and grid columns. Their syntax is defined in CSS Box Alignment 3 §8 Gaps Between Boxes.The effect of these properties is as though the affected grid lines acquired thickness: the grid track between two grid lines is the space between the gutters that represent them.

It's that simple.
Firstly, why doesn't your solution work. You mix up a lot of concepts. Mostly character class with other ones. In the first character class you use |
which stems from alternation. In character classes you don't need the pipe. Just list all characters (and character ranges) you want:
[Uu]
Or simply write u
if you use the case-insensitive modifier. If you write a pipe there, the character class will actually match pipes in your subject string.
Now in the second character class you use the comma to separate your characters for some odd reason. That does also nothing but include commas into the matchable characters. s
and W
are probably supposed to be the built-in character classes. Then escape them! Otherwise they will just match literal s
and literal W
. But then \W
already includes everything else you listed there, so a \W
alone (without square brackets) would have been enough. And the last part (^a-zA-Z)
also doesn't work, because it will simply include ^
, (
, )
and all letters into the character class. The negation syntax only works for entire character classes like [^a-zA-Z]
.
What you actually want is to assert that there is no letter in front or after your u
. You can use lookarounds for that. The advantage is that they won't be included in the match and thus won't be removed:
r'(?<![a-zA-Z])[uU](?![a-zA-Z])'
Note that I used a raw string. Is generally good practice for regular expressions, to avoid problems with escape sequences.
These are negative lookarounds that make sure that there is no letter character before or after your u
. This is an important difference to asserting that there is a non-letter character around (which is similar to what you did), because the latter approach won't work at the beginning or end of the string.
Of course, you can remove the spaces around you
from the replacement string.
If you don't want to replace u
that are next to digits, you can easily include the digits into the character classes:
r'(?<![a-zA-Z0-9])[uU](?![a-zA-Z0-9])'
And if for some reason an adjacent underscore would also disqualify your u
for replacement, you could include that as well. But then the character class coincides with the built-in \w
:
r'(?<!\w)[uU](?!\w)'
Which is, in this case, equivalent to EarlGray's r'\b[uU]\b'
.
As mentioned above you can shorten all of these, by using the case-insensitive modifier. Taking the first expression as an example:
re.sub(r'(?<![a-z])u(?![a-z])', 'you', text, flags=re.I)
or
re.sub(r'(?<![a-z])u(?![a-z])', 'you', text, flags=re.IGNORECASE)
depending on your preference.
I suggest that you do some reading through the tutorial I linked several times in this answer. The explanations are very comprehensive and should give you a good headstart on regular expressions, which you will probably encounter again sooner or later.
In postgres:
user = User.find(:first, :conditions => ['username ~* ?', "regedarek"])
Come 2021 and Spring Boot 2.4 the solution I have found is to have 3 properties files
src/main/resources/application.yml
- contains the application's default propssrc/test/resources/application.yml
- sets the profile to 'test', and imports properties from 'main'src/test/resources/application-test.yml
- contains test-specific profiles, which will override 'main'Here is the content of src/test/resources/application.yml
:
# for testing, set default profile to 'test'
spring.profiles.active: "test"
# and import the 'main' properties
spring.config.import: file:src/main/resources/application.yml
For example, if src/main/resources/application.yml
has the content
ip-address: "10.7.0.1"
username: admin
and src/test/resources/application-test.yml
has
ip-address: "999.999.999.999"
run-integration-test: true
Then (assuming there are no other profiles)...
when running tests,
profiles=test
--
ip-address=999.999.999.999
username=admin
run-integration-test=true
and when running the application normally
profiles=none
--
ip-address=10.7.0.1
username=admin
run-integration-test <undefined>
Simplest way to set image as JPanel background
Don't use a JPanel. Just use a JLabel with an Icon then you don't need custom code.
See Background Panel for more information as well as a solution that will paint the image on a JPanel with 3 different painting options:
If you need a function try this.
First we'll create a type:
CREATE OR REPLACE TYPE T_TABLE IS OBJECT
(
Field1 int
, Field2 VARCHAR(25)
);
CREATE TYPE T_TABLE_COLL IS TABLE OF T_TABLE;
/
Then we'll create the function:
CREATE OR REPLACE FUNCTION TEST_RETURN_TABLE
RETURN T_TABLE_COLL
IS
l_res_coll T_TABLE_COLL;
l_index number;
BEGIN
l_res_coll := T_TABLE_COLL();
FOR i IN (
WITH TAB AS
(SELECT '1001' ID, 'A,B,C,D,E,F' STR FROM DUAL
UNION
SELECT '1002' ID, 'D,E,F' STR FROM DUAL
UNION
SELECT '1003' ID, 'C,E,G' STR FROM DUAL
)
SELECT id,
SUBSTR(STR, instr(STR, ',', 1, lvl) + 1, instr(STR, ',', 1, lvl + 1) - instr(STR, ',', 1, lvl) - 1) name
FROM
( SELECT ',' || STR || ',' AS STR, id FROM TAB
),
( SELECT level AS lvl FROM dual CONNECT BY level <= 100
)
WHERE lvl <= LENGTH(STR) - LENGTH(REPLACE(STR, ',')) - 1
ORDER BY ID, NAME)
LOOP
IF i.ID = 1001 THEN
l_res_coll.extend;
l_index := l_res_coll.count;
l_res_coll(l_index):= T_TABLE(i.ID, i.name);
END IF;
END LOOP;
RETURN l_res_coll;
END;
/
Now we can select from it:
select * from table(TEST_RETURN_TABLE());
Output:
SQL> select * from table(TEST_RETURN_TABLE());
FIELD1 FIELD2
---------- -------------------------
1001 A
1001 B
1001 C
1001 D
1001 E
1001 F
6 rows selected.
Obviously you'd need to replace the WITH TAB AS...
bit with where you would be getting your actual data from.

help about_comparison_operators
displays help and includes this text:
All comparison operators except the containment operators (-contains, -notcontains) and type operators (-is, -isnot) return a Boolean value when the input to the operator (the value on the left side of the operator) is a single value (a scalar). When the input is a collection of values, the containment operators and the type operators return any matching values. If there are no matches in a collection, these operators do not return anything. The containment operators and type operators always return a Boolean value.

I would like to add to the answer provided by Sangam Belose. Here's his code:
select ('id') as id, ('time') as time, ('unit') as unit
UNION ALL
SELECT * INTO OUTFILE 'C:/Users/User/Downloads/data.csv'
FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"'
LINES TERMINATED BY '\n'
FROM sensor
However, if you have not set up your "secure_file_priv"
within the variables, it may not work. For that, check the folder set on that variable by:
SHOW VARIABLES LIKE "secure_file_priv"
The output should look like this:
mysql> show variables like "%secure_file_priv%";
+------------------+------------------------------------------------+
| Variable_name | Value |
+------------------+------------------------------------------------+
| secure_file_priv | C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\ |
+------------------+------------------------------------------------+
1 row in set, 1 warning (0.00 sec)
You can either change this variable or change the query to output the file to the default path showing.
I also just stumbled across this and the following seems to do the trick for me, on MySQL and PostgreSQL:

Unique annotation should be placed right above the attribute declaration. UniqueContraints go into the @Table annotation above the data class declaration. See below:
@Entity
@Table(uniqueConstraints= arrayOf(UniqueConstraint(columnNames = arrayOf("col_1", "col_2"))))
data class Action(
@Id @GeneratedValue @Column(unique = true)
val id: Long?,
val col_1: Long?,
val col_2: Long?,
)
The exception occurs due to this statement,
called_from.equalsIgnoreCase("add")
It seem that the previous statement
String called_from = getIntent().getStringExtra("called");
returned a null reference.
You can check whether the intent to start this activity contains such a key "called".
I hope ls -lah
will do the job. Also if you are new to unix environment please go to http://www.tutorialspoint.com/unix/unix-useful-commands.htm
I got a similar problem.
Due to timeout !
Timeout can be indicated like this :
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'method' => "POST",
'content' => http_build_query($data2),
'timeout' => 30,
),
);
$context = stream_context_create($options); $retour =
$retour = @file_get_contents("http://xxxxx.xxx/xxxx", false, $context);
(function(undefined){
var charsToReplace = {
'&': '&',
'<': '<',
'>': '>'
};
var replaceReg = new RegExp("[" + Object.keys(charsToReplace).join("") + "]", "g");
var replaceFn = function(tag){ return charsToReplace[tag] || tag; };
var replaceRegF = function(replaceMap) {
return (new RegExp("[" + Object.keys(charsToReplace).concat(Object.keys(replaceMap)).join("") + "]", "gi"));
};
var replaceFnF = function(replaceMap) {
return function(tag){ return replaceMap[tag] || charsToReplace[tag] || tag; };
};
String.prototype.htmlEscape = function(replaceMap) {
if (replaceMap === undefined) return this.replace(replaceReg, replaceFn);
return this.replace(replaceRegF(replaceMap), replaceFnF(replaceMap));
};
})();
No global variables, some memory optimization. Usage:
"some<tag>and&symbol©".htmlEscape({'©': '©'})
result is:
"some<tag>and&symbol©"
From a linear point of view, consider the matrices:
1 2 3 0 0 1
A = 4 5 6 B = 0 1 0
7 8 9 1 0 0
Now take A transpose
1 4 7
A' = 2 5 8
3 6 9
And consider the action of A' on B, or B on A'.
Respectively:
7 4 1 3 6 9
A'B = 8 5 2 BA' = 2 5 8
9 6 3 1 4 7
This is expandable for any n x n matrix. And applying this concept quickly in code:
void swapInSpace(int** mat, int r1, int c1, int r2, int c2)
{
mat[r1][c1] ^= mat[r2][c2];
mat[r2][c2] ^= mat[r1][c1];
mat[r1][c1] ^= mat[r2][c2];
}
void transpose(int** mat, int size)
{
for (int i = 0; i < size; i++)
{
for (int j = (i + 1); j < size; j++)
{
swapInSpace(mat, i, j, j, i);
}
}
}
void rotate(int** mat, int size)
{
//Get transpose
transpose(mat, size);
//Swap columns
for (int i = 0; i < size / 2; i++)
{
for (int j = 0; j < size; j++)
{
swapInSpace(mat, i, j, size - (i + 1), j);
}
}
}
And, just to throw it in the mix, is the oft-forgotten str.translate
which will work a lot faster than looping/regular expressions:
For Python 2:
from string import digits
s = 'abc123def456ghi789zero0'
res = s.translate(None, digits)
# 'abcdefghizero'
For Python 3:
from string import digits
s = 'abc123def456ghi789zero0'
remove_digits = str.maketrans('', '', digits)
res = s.translate(remove_digits)
# 'abcdefghizero'
The two methods previously described are not enough today. I personnally use :
input[type="text"]{
background-color: transparent;
border: 0px;
outline: none;
-webkit-box-shadow: none;
-moz-box-shadow: none;
box-shadow: none;
width:5px;
color:transparent;
cursor:default;
}
It also removes the shadow set on some browsers, hide the text that could be input and make the cursor behave as if the input was not there.
You may want to set width to 0px also.
My observations based on a few tests has been that whichever name differs from the property name is one which takes effect:
For eg. consider a slight modification of your case:
@JsonProperty("fileName")
private String fileName;
@JsonProperty("fileName")
public String getFileName()
{
return fileName;
}
@JsonProperty("fileName1")
public void setFileName(String fileName)
{
this.fileName = fileName;
}
Both fileName
field, and method getFileName
, have the correct property name of fileName
and setFileName
has a different one fileName1
, in this case Jackson will look for a fileName1
attribute in json at the point of deserialization and will create a attribute called fileName1
at the point of serialization.
Now, coming to your case, where all the three @JsonProperty differ from the default propertyname of fileName
, it would just pick one of them as the attribute(FILENAME
), and had any on of the three differed, it would have thrown an exception:
java.lang.IllegalStateException: Conflicting property name definitions
You don't need both hibernate.cfg.xml
and persistence.xml
in this case. Have you tried removing hibernate.cfg.xml
and mapping everything in persistence.xml
only?
But as the other answer also pointed out, this is not okay like this:
@Id
@JoinColumn(name = "categoria")
private String id;
Didn't you want to use @Column
instead?
