You need to prevent the default event (following the link), otherwise your link will load a new page:
$(document).ready(function(){
$('.play_navigation a').click(function(e){
e.preventDefault();
console.log("this is the click");
});
});
As pointed out in comments, if your link has no href, then it's not a link, use something else.
Not working? Your code is A MESS! and ready() events everywhere... clean it, put all your scripts in ONE ready event and then try again, it will very likely sort things out.
fname = 'filenotfound.txt'
try:
f = open(fname, 'rb')
except FileNotFoundError:
print("file {} does not exist".format(fname))
file filenotfound.txt does not exist
exception FileNotFoundError Raised when a file or directory is requested but doesn’t exist. Corresponds to errno ENOENT.
https://docs.python.org/3/library/exceptions.html
This exception does not exist in Python 2.
Windows 10:
open cmd
change directory where you want to create text file(movie_list.txt) for the folder (d:\videos\movies)
type following command
d:\videos\movies> dir /b /a-d > movie_list.txt
Please try running
brew install docker
This will install the Docker engine, which will require Docker-Machine (+ VirtualBox) to run on the Mac.
If you want to install the newer Docker for Mac, which does not require virtualbox, you can install that through Homebrew's Cask:
brew install --cask docker
open /Applications/Docker.app
C99 added a builtin _Bool
data type (see Wikipedia for details), and if you #include <stdbool.h>
, it provides bool
as a macro to _Bool
.
You asked about the Linux kernel in particular. It assumes the presence of _Bool
and provides a bool
typedef itself in include/linux/types.h.
If you don't want the hassle of using mail
, you can read the mail with
cat /var/mail/<username>
and delete the mail with
sudo rm /var/mail/<username>
Here's a zsh-only function that I like for its compactness. It uses the ‘A’ expansion modifier — see zshexpn(1).
realpath() { for f in "$@"; do echo ${f}(:A); done }
The easiest way to achieve is by applying width to view.
width: '80%'
I'm assume you cannot get css working for your button using anchor tag. So you need to override the css styles which are being overwritten by other elements using !important
property.
HTML
<a href="#" class="selected_btn" data-role="button">Button name</a>
CSS
.selected_btn
{
border:1px solid red;
text-decoration:none;
font-family:helvetica;
color:red !important;
background:url('http://www.lessardstephens.com/layout/images/slideshow_big.png') repeat-x;
}
Here is the demo
You can create a RegExp
object to make it a bit more readable
str.replace(new RegExp('/'), 'foobar');
If you want to replace all of them add the "g"
flag
str.replace(new RegExp('/', 'g'), 'foobar');
In each class that you need to inherit from, you can run a loop of each class that needs init'd upon initiation of the child class...an example that can copied might be better understood...
class Female_Grandparent:
def __init__(self):
self.grandma_name = 'Grandma'
class Male_Grandparent:
def __init__(self):
self.grandpa_name = 'Grandpa'
class Parent(Female_Grandparent, Male_Grandparent):
def __init__(self):
Female_Grandparent.__init__(self)
Male_Grandparent.__init__(self)
self.parent_name = 'Parent Class'
class Child(Parent):
def __init__(self):
Parent.__init__(self)
#---------------------------------------------------------------------------------------#
for cls in Parent.__bases__: # This block grabs the classes of the child
cls.__init__(self) # class (which is named 'Parent' in this case),
# and iterates through them, initiating each one.
# The result is that each parent, of each child,
# is automatically handled upon initiation of the
# dependent class. WOOT WOOT! :D
#---------------------------------------------------------------------------------------#
g = Female_Grandparent()
print g.grandma_name
p = Parent()
print p.grandma_name
child = Child()
print child.grandma_name
I like this solution for small applications:
class App:
__conf = {
"username": "",
"password": "",
"MYSQL_PORT": 3306,
"MYSQL_DATABASE": 'mydb',
"MYSQL_DATABASE_TABLES": ['tb_users', 'tb_groups']
}
__setters = ["username", "password"]
@staticmethod
def config(name):
return App.__conf[name]
@staticmethod
def set(name, value):
if name in App.__setters:
App.__conf[name] = value
else:
raise NameError("Name not accepted in set() method")
And then usage is:
if __name__ == "__main__":
# from config import App
App.config("MYSQL_PORT") # return 3306
App.set("username", "hi") # set new username value
App.config("username") # return "hi"
App.set("MYSQL_PORT", "abc") # this raises NameError
.. you should like it because:
App
, @property
, but that requires more variable handling code per item and is object-based.--Edit--: For large applications, storing values in a YAML (i.e. properties) file and reading that in as immutable data is a better approach (i.e. blubb/ohaal's answer). For small applications, this solution above is simpler.
For only pick from local add this :
i.putExtra(Intent.EXTRA_LOCAL_ONLY,true)
And this working nice :
val i = Intent(Intent.ACTION_GET_CONTENT,MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
i.type = "image/*"
i.putExtra(Intent.EXTRA_LOCAL_ONLY,true)
startActivityForResult(Intent.createChooser(i,"Select Photo"),pickImageRequestCode)
The best solution is just not to use anonymous classes.
public class Test
{
class DummyInterfaceImplementor : IDummyInterface
{
public string A { get; set; }
public string B { get; set; }
}
public void WillThisWork()
{
var source = new DummySource[0];
var values = from value in source
select new DummyInterfaceImplementor()
{
A = value.A,
B = value.C + "_" + value.D
};
DoSomethingWithDummyInterface(values.Cast<IDummyInterface>());
}
public void DoSomethingWithDummyInterface(IEnumerable<IDummyInterface> values)
{
foreach (var value in values)
{
Console.WriteLine("A = '{0}', B = '{1}'", value.A, value.B);
}
}
}
Note that you need to cast the result of the query to the type of the interface. There might be a better way to do it, but I couldn't find it.
You can use the following:
$regex = '#<\s*?code\b[^>]*>(.*?)</code\b[^>]*>#s';
\b
ensures that a typo (like <codeS>
) is not captured.[^>]*
captures the content of a tag with attributes (eg a class).s
capture content with newlines.See the result here : http://lumadis.be/regex/test_regex.php?id=1081
MD5 also benefits from SSE2 usage, check out BarsWF and then tell me that it doesn't. All it takes is a little assembler knowledge and you can craft your own MD5 SSE2 routine(s). For large amounts of throughput however, there is a tradeoff of the speed during hashing as opposed to the time spent rearranging the input data to be compatible with the SIMD instructions used.
There are multiple ways to do it, let's run this script called exercise.sh
#!/usr/bin/env bash
> file1.txt cat <<< "This is a here-string with random value $RANDOM"
# Or if you prefer to see what is happening and write to file as well
tee file2.txt <<< "Here is another here-string I can see and write to file"
# if you want to work multiline easily
cat <<EOF > file3.txt
You don't need to escape any quotes here, $ marks start of variables, unless escaped.
This is random value from variable $RANDOM
This is literal \$RANDOM
EOF
# Let's say you have a variable with multiline text and you want to manipulate it
a="
1
2
3
33
"
# Assume I want to have lines containing "3". Instead of grep it can even be another script
a=$(echo "$a" | grep 3)
# Then you want to write this to a file, although here-string is fine,
# if you don't need single-liner command, prefer heredoc
# Herestring. (If it's single liner, variable needs to be quoted to preserve newlines)
> file4.txt cat <<< "$a"
# Heredoc
cat <<EOF > file5.txt
$a
EOF
This is the output you should see:
$ bash exercise.sh
Here is another here-string I can see and write to file
And files should contain these:
$ ls
exercise.sh file1.txt file2.txt file3.txt file4.txt file5.txt
$ cat file1.txt
This is a here-string with random value 20914
$ cat file2.txt
Here is another here-string I can see and write to file
$ cat file3.txt
You don't need to escape any quotes here, $ marks start of variables, unless escaped.
This is random value from variable 15899
This is literal $RANDOM
$ cat file4.txt
3
33
$ cat file5.txt

@Simple-Solution
I use a simple Python HTTP server. When in the directory of the Angular app in question (using a MBP with Mavericks 10.9 and Python 2.x) I simply run
python -m SimpleHTTPServer 8080
And that sets up the simple server on port 8080 letting you visit localhost:8080
on your browser to view the app in development.
Hope that helped!
I hope your stored procedure is not doing a cursor loop!
If not, take the query from your stored procedure and integrate that query within the query you are posting here:
SELECT t.TenantName, t.CarPlateNumber, t.CarColor, t.Sex, t.SSNO, t.Phone, t.Memo,
u.UnitNumber,
p.PropertyName
,dt.TenantBalance
FROM tblTenant t
LEFT JOIN tblRentalUnit u ON t.UnitID = u.ID
LEFT JOIN tblProperty p ON u.PropertyID = p.ID
LEFT JOIN (SELECT ID, SUM(ISNULL(trans.Amount,0)) AS TenantBalance
FROM tblTransaction
GROUP BY tenant.ID
) dt ON t.ID=dt.ID
ORDER BY p.PropertyName, t.CarPlateNumber
If you are doing something more than a query in your stored procedure, create a temp table and execute the stored procedure into this temp table and then join to that in your query.
create procedure test_proc
as
select 1 as x, 2 as y
union select 3,4
union select 5,6
union select 7,8
union select 9,10
return 0
go
create table #testing
(
value1 int
,value2 int
)
INSERT INTO #testing
exec test_proc
select
*
FROM #testing
Simple PHP solution for subdomains and multi-domain web apps
Step 1. Provide DNS A record as "*" for domains (or domain) you gonna serve "example.org"
A record => *.example.org
A record => *.example.net
Step 2. Check uniquity of logins when user registering or changing login. Also, avoid dots in those logins.
Step 3. Then check the query
// Request was http://qwerty.example.org
$q = explode('.', $_SERVER['HTTP_HOST']);
/*
We get following array
Array
(
[0] => qwerty
[1] => example
[2] => org
)
*/
// Step 4.
// If second piece of array exists, request was for
// SUBDOMAIN which is stored in zero-piece $q[0]
// otherwise it was for DOMAIN
if(isset($q[2])) {
// Find stuff in database for login $q[0] or here it is "qwerty"
// Use $q[1] to check which domain is asked if u serve multiple domains
}
?>
This solution may serve different domains
qwerty.example.org
qwerty.example.net
johnsmith.somecompany.com
paulsmith.somecompany.com
If you need same nicks on different domains served differently, you may need to store user choise for domain when registering login.
smith.example.org // Show info about John Smith
smith.example.net // Show info about Paul Smith
In the case of my Cordova-project, uninstalling and installing cordova -g fixed the problem for me.
npm uninstall -g cordova
npm install -g cordova
If you want to launch VM by sending arguments, you should send VM arguments and not Program arguments.
Program arguments are arguments that are passed to your application, which are accessible via the "args" String array parameter of your main method. VM arguments are arguments such as System properties that are passed to the JavaSW interpreter. The Debug configuration above is essentially equivalent to:
java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3
The VM arguments go after the call to your Java interpreter (ie, 'java') and before the Java class. Program arguments go after your Java class.
Consider a program ArgsTest.java:
package test;
import java.io.IOException;
public class ArgsTest {
public static void main(String[] args) throws IOException {
System.out.println("Program Arguments:");
for (String arg : args) {
System.out.println("\t" + arg);
}
System.out.println("System Properties from VM Arguments");
String sysProp1 = "sysProp1";
System.out.println("\tName:" + sysProp1 + ", Value:" + System.getProperty(sysProp1));
String sysProp2 = "sysProp2";
System.out.println("\tName:" + sysProp2 + ", Value:" + System.getProperty(sysProp2));
}
}
If given input as,
java -DsysProp1=sp1 -DsysProp2=sp2 test.ArgsTest pro1 pro2 pro3
in the commandline, in project bin folder would give the following result:
Program Arguments: pro1 pro2 pro3 System Properties from VM Arguments Name:sysProp1, Value:sp1 Name:sysProp2, Value:sp2
ECMAScript = ES:
ECMAScript is a Standard for scripting languages.
Languages like Javascript are based on the ECMAScript standard.
ECMA Standard is based on several originating technologies, the most well known being JavaScript (Netscape) and JScript (Microsoft).
ECMA means European Computer Manufacturer’s Association
JavaScript = JS:
JavaScript is the most popular implementation of the ECMAScript Standard.
The core features of Javascript are based on the ECMAScript standard, but Javascript also has other additional features that are not in the ECMA specifications/standard.
ActionScript and JScript are other languages that implement the ECMAScript.
JavaScript was submitted to ECMA for standardization but due to trademark issues with the name Javascript the standard became called ECMAScript.
Every browser has a JavaScript interpreter.
ES5 = ECMAScript 5:
ES5 is a version of the ECMAScript (old/current one).
ES5 is the JavaScript you know and use in the browser today.
ES5 does not require a build step (transpilers) to transform it into something that will run in today's browsers.
ECMAScript version 5 was finished in December 2009, the latest versions of all major browsers (Chrome, Safari, Firefox, and IE) have implemented version 5.
Version 5.1 was finished in June, 2011.
ES6 = ECMAScript 6 = ES2015 = ECMAScript 2015:
ES2015 is a version of the ECMAScript (new/future one).
Officially the name ES2015 should be used instead of ES6.
ES6 will tackle many of the core language shortcomings addressed in TypeScript and CoffeeScript.
ES6 is the next iteration of JavaScript, but it does not run in today's browsers.
There are quite a few transpilers that will export ES5 for running in browsers.
BabelJS:
BabelJS is the most popular transpiler that transforms new JavaScript ES6 to Old JavaScript ES5.
BabelJS makes it possible for writing the next generation of JavaScript today (means ES2015).
BabelJS simply takes ES2015 file and transform it into ES5 file.
Current browsers versions can now understand the new JavaScript code (ES2015), even if they don't yet support it.
TypeScript and CoffeeScript:
Both provides syntactic sugar on top of ES5 and then are transcompiled into ES5 compliant JavaScript.
You write TypeScript or CoffeeScript then the transpiler transforms it into ES5 JavaScript.
Have you looked at the Maven Dependency Plugin ? That won't remove stuff for you but has tools to allow you to do the analysis yourself. I'm thinking particularly of
mvn dependency:tree
You want the -u
option for sudo
in this case. From the man
page:
The -u (user) option causes sudo to run the specified command as a user other than root.
If you don't need to actually run it as them, you could move to their home directory with ~<user>
. As in, to move into my home directory you would use cd ~chooban
.
I know the question is about setting a input but just in case if you want to set a combobox then (I search net for it and didn't find anything and this place seems a right place to guide others)
If you had a form with ID attribute set (e.g. frm1) and you wanted to set a specific specific combobox, with no ID set but name attribute set (e.g. district); then use
$("#frm1 select[name='district'] option[value='NWFP']").attr('selected', true);
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>_x000D_
<form id="frm1">_x000D_
<select name="district">_x000D_
<option value="" disabled="" selected="" hidden="">Area ...</option>_x000D_
<option value="NWFP">NWFP</option>_x000D_
<option value="FATA">FATA</option>_x000D_
</select>_x000D_
</form>

I was able to setup a SSL certificated for a domain AND multiple subdomains by using using --cert-name
combined with --expand
options.
See official certbot-auto documentation at https://certbot.eff.org/docs/using.html
Example:
certbot-auto certonly --cert-name mydomain.com.br \
--renew-by-default -a webroot -n --expand \
--webroot-path=/usr/share/nginx/html \
-d mydomain.com.br \
-d www.mydomain.com.br \
-d aaa1.com.br \
-d aaa2.com.br \
-d aaa3.com.br
To change indicator color and height programmatically you can use reflection. for example for indicator color use code below:
try {
Field field = TabLayout.class.getDeclaredField("mTabStrip");
field.setAccessible(true);
Object ob = field.get(tabLayout);
Class<?> c = Class.forName("android.support.design.widget.TabLayout$SlidingTabStrip");
Method method = c.getDeclaredMethod("setSelectedIndicatorColor", int.class);
method.setAccessible(true);
method.invoke(ob, Color.RED);//now its ok
} catch (NoSuchFieldException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
and to change indicator height use "setSelectedIndicatorHeight" instead of "setSelectedIndicatorColor" then invoke it by your desired height
You can use phpseclib, a pure PHP RSA implementation:
<?php
include('Crypt/RSA.php');
$privatekey = file_get_contents('private.key');
$rsa = new Crypt_RSA();
$rsa->loadKey($privatekey);
$plaintext = new Math_BigInteger('aaaaaa');
echo $rsa->_exponentiate($plaintext)->toBytes();
?>
We ran into this problem because we had set up CORS according to best practice (e.g. http://www.asp.net/web-api/overview/security/enabling-cross-origin-requests-in-web-api) AND ALSO had a custom header <add name="Access-Control-Allow-Origin" value="*"/>
in web.config.
Remove the web.config entry, and all is well.
Contrary to @mww's answer, we still have EnableCors()
in the WebApiConfig.cs AND an EnableCorsAttribute
on the controller. When we took out one or the other, we ran into other issues.

How i deal with EXC_BAD_ACCESS
Sometimes i feel that when a EXC_BAD_ACCESS error is thrown xcode will show the error in the main.m class giving no extra information of where the crash happens(Sometimes).
In those times we can set a Exceptional Breakpoint in Xcode so that when exception is caught a breakpoint will be placed and will directly intimate the user that crash has happened in that line
As I wrote in my comment, the solution to your problem is to write the following:
Set hyperLinkText = hprlink.Range
Set
is needed because TextRange
is a class, so hyperLinkText
is an object; as such, if you want to assign it, you need to make it point to the actual object that you need.
Check your server config file /etc/mysql/my.cnf
- verify bind_address
is not set to 127.0.0.1
. Set it to 0.0.0.0
or comment it out then restart server with:
sudo service mysql restart
The above answers only work if AllowUserToAddRows
is set to false
. If that property is set to true
, then you will get a NullReferenceException
when the loop or Linq query tries to negotiate the new row. I've modified the two accepted answers above to handle AllowUserToAddRows = true
.
Loop answer:
String searchValue = "somestring";
int rowIndex = -1;
foreach(DataGridViewRow row in DataGridView1.Rows)
{
if (row.Cells["SystemId"].Value != null) // Need to check for null if new row is exposed
{
if(row.Cells["SystemId"].Value.ToString().Equals(searchValue))
{
rowIndex = row.Index;
break;
}
}
}
LINQ answer:
int rowIndex = -1;
bool tempAllowUserToAddRows = dgv.AllowUserToAddRows;
dgv.AllowUserToAddRows = false; // Turn off or .Value below will throw null exception
DataGridViewRow row = dgv.Rows
.Cast<DataGridViewRow>()
.Where(r => r.Cells["SystemId"].Value.ToString().Equals(searchValue))
.First();
rowIndex = row.Index;
dgv.AllowUserToAddRows = tempAllowUserToAddRows;
Just to add one more point to this:
R does have a data structure equivalent to the Python dict in the hash
package. You can read about it in this blog post from the Open Data Group. Here's a simple example:
> library(hash)
> h <- hash( keys=c('foo','bar','baz'), values=1:3 )
> h[c('foo','bar')]
<hash> containing 2 key-value pairs.
bar : 2
foo : 1
In terms of usability, the hash
class is very similar to a list. But the performance is better for large datasets.
For me it worked with:
unset TMPDIR
mysql_install_db --user=`whoami` --basedir="$(brew --prefix mariadb)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

Deleting is such a headache. I am posting the solution for Android Studio 1.0.2.
Step 1: Right click on the "Project Name" selected from the folder hierarchy like shown.
Note: It can also be deleted from the Commander View from right hand side of your window by right clicking the project name and selecting delete from the context menu.
Step 2: The project is deleted(seemingly) but gradle seems to keep the record of the project app folder(Check it by clcking on the Gradle View). Now go to File->Close Project.
Step 3: Now you are at the start window. Move the cursor on the in recent project list. Press Delete.
Step 4: Delete the folder from the explorer by moving or deleting it actually. This location is in your_user_name->Android Studio Projects->...
Step 5: Go back to the Android studio window and the project is gone for good. You can start a new project now.
Is this what you mean?

I have posted the answer to a similar question here.
Another approach is to add a toString()
method to your Car
class and just let the toString()
method of ArrayList do all the work.
@Override
public String toString()
{
return "Car{" +
"make=" + make +
", registration='" + registration + '\'' +
'}';
}
You don't get one car per line in the output, but it is quick and easy if you just want to see what is in the array.
List<Car> cars = c1.getAll();
System.out.println(cars);
Output would be something like this:
[Car{make=FORD, registration='ABC 123'},
Car{make=TOYOTA, registration='ZYZ 999'}]
var e = $('<div style="display:block; id="myid" float:left;width:'+width+'px; height:'+height+'px; margin-top:'+positionY+'px;margin-left:'+positionX+'px;border:1px dashed #CCCCCC;"></div>');
$("#box").html(e);

The answer to my own question is, I think, to use tomcat7.exe:
cd $CATALINA_HOME
.\bin\service.bat install tomcat
.\bin\tomcat7.exe //US//tomcat7 --JvmMs=512 --JvmMx=1024 --JvmSs=1024
Also, you can launch the UI tool mentioned by BalusC without the system tray or using the installer with tomcat7w.exe
.\bin\tomcat7w.exe //ES//tomcat
An additional note to this:
Setting the --JvmXX parameters (through the UI tool or the command line) may not be enough. You may also need to specify the JVM memory values explicitly. From the command line it may look like this:
bin\tomcat7w.exe //US//tomcat7 --JavaOptions=-Xmx=1024;-Xms=512;..
Be careful not to override the other JavaOption values. You can try updating bin\service.bat or use the UI tool and append the java options (separate each value with a new line).
You are iterating over one string (word
), but then using the index into that to look up a character in so_far
. There is no guarantee that these two strings have the same length.
GET: Usually used for submitted search requests, or any request where you want the user to be able to pull up the exact page again.
Advantages of GET:
Disadvantages of GET:
POST: Used for higher security requests where data may be used to alter a database, or a page that you don't want someone to bookmark.
Advantages of POST:
Disadvantages of POST:
Directly from the Hypertext Transfer Protocol -- HTTP/1.1:
9.3 GET
The GET method means retrieve whatever information (in the form of an entity) is identified by the Request-URI. If the Request-URI refers to a data-producing process, it is the produced data which shall be returned as the entity in the response and not the source text of the process, unless that text happens to be the output of the process.
The semantics of the GET method change to a "conditional GET" if the request message includes an If-Modified-Since, If-Unmodified-Since, If-Match, If-None-Match, or If-Range header field. A conditional GET method requests that the entity be transferred only under the circumstances described by the conditional header field(s). The conditional GET method is intended to reduce unnecessary network usage by allowing cached entities to be refreshed without requiring multiple requests or transferring data already held by the client.
The semantics of the GET method change to a "partial GET" if the request message includes a Range header field. A partial GET requests that only part of the entity be transferred, as described in section 14.35. The partial GET method is intended to reduce unnecessary network usage by allowing partially-retrieved entities to be completed without transferring data already held by the client.
The response to a GET request is cacheable if and only if it meets the requirements for HTTP caching described in section 13.
See section 15.1.3 for security considerations when used for forms.
9.5 POST
The POST method is used to request that the origin server accept the entity enclosed in the request as a new subordinate of the resource identified by the Request-URI in the Request-Line. POST is designed to allow a uniform method to cover the following functions:
Annotation of existing resources;
Posting a message to a bulletin board, newsgroup, mailing list, or similar group of articles;
Providing a block of data, such as the result of submitting a form, to a data-handling process;
Extending a database through an append operation.
The actual function performed by the POST method is determined by the server and is usually dependent on the Request-URI. The posted entity is subordinate to that URI in the same way that a file is subordinate to a directory containing it, a news article is subordinate to a newsgroup to which it is posted, or a record is subordinate to a database.
The action performed by the POST method might not result in a resource that can be identified by a URI. In this case, either 200 (OK) or 204 (No Content) is the appropriate response status, depending on whether or not the response includes an entity that describes the result.
Hey Try This Code.

Actually python will reclaim the memory which is not in use anymore.This is called garbage collection which is automatic process in python. But still if you want to do it then you can delete it by del variable_name
. You can also do it by assigning the variable to None
a = 10
print a
del a
print a ## throws an error here because it's been deleted already.
The only way to truly reclaim memory from unreferenced Python objects is via the garbage collector. The del keyword simply unbinds a name from an object, but the object still needs to be garbage collected. You can force garbage collector to run using the gc module, but this is almost certainly a premature optimization but it has its own risks. Using del
has no real effect, since those names would have been deleted as they went out of scope anyway.

An alias will expand to the string it represents. Anything after the alias will appear after its expansion without needing to be or able to be passed as explicit arguments (e.g. $1
).
$ alias foo='/path/to/bar'
$ foo some args
will get expanded to
$ /path/to/bar some args
If you want to use explicit arguments, you'll need to use a function
$ foo () { /path/to/bar "$@" fixed args; }
$ foo abc 123
will be executed as if you had done
$ /path/to/bar abc 123 fixed args
To undefine an alias:
unalias foo
To undefine a function:
unset -f foo
To see the type and definition (for each defined alias, keyword, function, builtin or executable file):
type -a foo
Or type only (for the highest precedence occurrence):
type -t foo
It is not clear to me what you mean by "escape an executable which is running", but ctrl-z will put a process into the background and return control to the command line. You can then use the fg command to bring the program back into the foreground.
Use pandas.Series.dt.day_name()
, since pandas.Timestamp.weekday_name
has been deprecated:
import pandas as pd
df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])
df['day_of_week'] = df['my_dates'].dt.day_name()
Output:
my_dates myvals day_of_week
0 2015-01-01 1 Thursday
1 2015-01-02 2 Friday
2 2015-01-03 3 Saturday
As user jezrael points out below, dt.weekday_name
was added in version 0.18.1
Pandas Docs
import pandas as pd
df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])
df['day_of_week'] = df['my_dates'].dt.weekday_name
Output:
my_dates myvals day_of_week
0 2015-01-01 1 Thursday
1 2015-01-02 2 Friday
2 2015-01-03 3 Saturday
Use this:
http://pandas.pydata.org/pandas-docs/stable/generated/pandas.Series.dt.dayofweek.html
See this:
Get weekday/day-of-week for Datetime column of DataFrame
If you want a string instead of an integer do something like this:
import pandas as pd
df = pd.DataFrame({'my_dates':['2015-01-01','2015-01-02','2015-01-03'],'myvals':[1,2,3]})
df['my_dates'] = pd.to_datetime(df['my_dates'])
df['day_of_week'] = df['my_dates'].dt.dayofweek
days = {0:'Mon',1:'Tues',2:'Weds',3:'Thurs',4:'Fri',5:'Sat',6:'Sun'}
df['day_of_week'] = df['day_of_week'].apply(lambda x: days[x])
Output:
my_dates myvals day_of_week
0 2015-01-01 1 Thurs
1 2015-01-02 2 Fri
2 2015-01-01 3 Thurs
var myObj = {
1: [1, 2, 3],
2: [4, 5, 6]

console.log(array);
Output:
[[1, 2, 3], [4, 5, 6]]
Such thing is easy with ggplot2
library(ggplot2)
dataset <- data.frame(X = c(rep(65, times=5), rep(25, times=5),
rep(35, times=10), rep(45, times=4)))
ggplot(dataset, aes(x = X)) +
geom_histogram(aes(y = ..density..)) +
geom_density()
or to mimic the result from Dirk's solution
ggplot(dataset, aes(x = X)) +
geom_histogram(aes(y = ..density..), binwidth = 5) +
geom_density()
LD_LIBRARY_PATH

The getimagesize() should be the most definite way of working out whether the file is an image:
if(@is_array(getimagesize($mediapath))){
$image = true;
} else {
$image = false;
}
because this is a sample getimagesize() output:
Array (
[0] => 800
[1] => 450
[2] => 2
[3] => width="800" height="450"
[bits] => 8
[channels] => 3
[mime] => image/jpeg)
I believe you are looking for this:
string str = "{\"Arg1\":\"Arg1Value\",\"Arg2\":\"Arg2Value\"}";
JavaScriptSerializer serializer1 = new JavaScriptSerializer();
object obje = serializer1.Deserialize(str, obj1.GetType());
On a vanilla Apache2 install in CentOS, when you install mod_ssl it will automatically add a configuration file in:
{apache_dir}/conf.d/ssl.conf
This configuration file contains a default virtual host definition for port 443, named default:443. If you also have your own virtual host definition for 443 (i.e. in httpd.conf) then you will have a confict. Since the conf.d files are included first, they will win over yours.
To solve the conflict you can either remove the virtual host definition from conf.d/ssl.conf
or update it to your own settings.
For those interested, there is no:
<xsl:tag-of select="."/>
However you can re-create the tag/element by going:
<xsl:element name="{local-name()}">
<xsl:value-of select="substring(.,1,3)"/>
</xsl:element>
This is useful in an xslt template that for example handles formatting data values for lots of different elements. When you don't know the name of the element being worked on and you can still output the same element, and modify the value if need be.
Try to use (focusout) instead of (blur)
Based on the discussion in the comments (particularly from BalusC), it's probably not worth doing anything more complicated than this:

Another option is to write to a temporary file to prevent the stdout blocking instead of needing to poll with communicate(). This worked for me where the other answers did not; for example on windows.
outFile = tempfile.SpooledTemporaryFile()
errFile = tempfile.SpooledTemporaryFile()
proc = subprocess.Popen(args, stderr=errFile, stdout=outFile, universal_newlines=False)
wait_remaining_sec = timeout
while proc.poll() is None and wait_remaining_sec > 0:
time.sleep(1)
wait_remaining_sec -= 1
if wait_remaining_sec <= 0:
killProc(proc.pid)
raise ProcessIncompleteError(proc, timeout)
# read temp streams from start
outFile.seek(0);
errFile.seek(0);
out = outFile.read()
err = errFile.read()
outFile.close()
errFile.close()
The ?type=daily
argument (ending up in the $_GET
array) is only valid for web-accessed pages.
You'll need to call it like php myfile.php daily
and retrieve that argument from the $argv
array (which would be $argv[1]
, since $argv[0]
would be myfile.php
).
If the page is used as a webpage as well, there are two options you could consider. Either accessing it with a shell script and Wget, and call that from cron:
#!/bin/sh
wget http://location.to/myfile.php?type=daily
Or check in the PHP file whether it's called from the command line or not:
if (defined('STDIN')) {
$type = $argv[1];
} else {
$type = $_GET['type'];
}
(Note: You'll probably need/want to check if $argv
actually contains enough variables and such)
The correct way to create a user in Django is to use the create_user function. This will handle the hashing of the password, etc..

Also seems nobody noticed -x operator on symlinks. A symlink (chain) to a regular file (not classified as executable) fails the test.
Here is an alternative which uses a custom output iterator. This example behaves correctly for the case of an empty list. This example demonstrates how to create a custom output iterator, similar to std::ostream_iterator
.
#include <iterator>
#include <vector>
#include <iostream>
#include <sstream>
struct CommaIterator
:
public std::iterator<std::output_iterator_tag, void, void, void, void>
{
std::ostream *os;
std::string comma;
bool first;
CommaIterator(std::ostream& os, const std::string& comma)
:
os(&os), comma(comma), first(true)
{
}
CommaIterator& operator++() { return *this; }
CommaIterator& operator++(int) { return *this; }
CommaIterator& operator*() { return *this; }
template <class T>
CommaIterator& operator=(const T& t) {
if(first)
first = false;
else
*os << comma;
*os << t;
return *this;
}
};
int main () {
// The vector to convert
std::vector<int> v(3,3);
// Convert vector to string
std::ostringstream oss;
std::copy(v.begin(), v.end(), CommaIterator(oss, ","));
std::string result = oss.str();
const char *c_result = result.c_str();
// Display the result;
std::cout << c_result << "\n";
}

If anyone stumblng here has problems with internal grid selection happening after OnSelectionChanged - after unsuccessfully trying out all the selection setters for a dozen hours the only thing that worked for me was reloading and repopulating DataGrid along with selected item.

datagrid.ItemsSource = null
datagrid.ItemsSource = items;
datagrid.SelectedItem = selectedItem;
I don't know what you mean by "data dont get lost". Here's how you pass a normal 2D array to a function:

int somearr[M][N];
...
myfunc(somearr);
...
}
function fixNumericScrolling() {
$$( "input[type=number]" ).addEvent( "mousewheel", function(e) {

Folks you can see what the optimizer is doing by running a plan. The generic format of looking into a plan is from the MongoDB documentation . i.e. Cursor.plan()
. If you really want to dig deeper you can do a cursor.plan(true)
for more details.
Having said that if you have an index, your db.col.find().sort({"field":-1}).limit(1)
will read one index entry - even if the index is default ascending and you wanted the max entry and one value from the collection.
In other words the suggestions from @yogesh is correct.

C++11 added alias declarations, which are generalization of typedef
, allowing templates:
template <size_t N>
using Vector = Matrix<N, 1>;
The type Vector<3>
is equivalent to Matrix<3, 1>
.
In C++03, the closest approximation was:
template <size_t N>
struct Vector
{
typedef Matrix<N, 1> type;
};
Here, the type Vector<3>::type
is equivalent to Matrix<3, 1>
.
You could replace the original jQuery addClass and removeClass functions with your own that would call the original functions and then trigger a custom event. (Using a self-invoking anonymous function to contain the original function reference)
(function( func ) {
$.fn.addClass = function() { // replace the existing function on $.fn
func.apply( this, arguments ); // invoke the original function
this.trigger('classChanged'); // trigger the custom event
return this; // retain jQuery chainability
}
})($.fn.addClass); // pass the original function as an argument
(function( func ) {
$.fn.removeClass = function() {
func.apply( this, arguments );
this.trigger('classChanged');
return this;
}
})($.fn.removeClass);
Then the rest of your code would be as simple as you'd expect.
$(selector).on('classChanged', function(){ /*...*/ });
Update:
This approach does make the assumption that the classes will only be changed via the jQuery addClass and removeClass methods. If classes are modified in other ways (such as direct manipulation of the class attribute through the DOM element) use of something like MutationObserver
s as explained in the accepted answer here would be necessary.
Also as a couple improvements to these methods:
classAdded
) or removed (classRemoved
) with the specific class passed as an argument to the callback function and only triggered if the particular class was actually added (not present previously) or removed (was present previously)Only trigger classChanged
if any classes are actually changed
(function( func ) {
$.fn.addClass = function(n) { // replace the existing function on $.fn
this.each(function(i) { // for each element in the collection
var $this = $(this); // 'this' is DOM element in this context
var prevClasses = this.getAttribute('class'); // note its original classes
var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString(); // retain function-type argument support
$.each(classNames.split(/\s+/), function(index, className) { // allow for multiple classes being added
if( !$this.hasClass(className) ) { // only when the class is not already present
func.call( $this, className ); // invoke the original function to add the class
$this.trigger('classAdded', className); // trigger a classAdded event
}
});
prevClasses != this.getAttribute('class') && $this.trigger('classChanged'); // trigger the classChanged event
});
return this; // retain jQuery chainability
}
})($.fn.addClass); // pass the original function as an argument
(function( func ) {
$.fn.removeClass = function(n) {
this.each(function(i) {
var $this = $(this);
var prevClasses = this.getAttribute('class');
var classNames = $.isFunction(n) ? n(i, prevClasses) : n.toString();
$.each(classNames.split(/\s+/), function(index, className) {
if( $this.hasClass(className) ) {
func.call( $this, className );
$this.trigger('classRemoved', className);
}
});
prevClasses != this.getAttribute('class') && $this.trigger('classChanged');
});
return this;
}
})($.fn.removeClass);
With these replacement functions you can then handle any class changed via classChanged or specific classes being added or removed by checking the argument to the callback function:
$(document).on('classAdded', '#myElement', function(event, className) {
if(className == "something") { /* do something */ }
});
I think this is the correct answer for csh.
xxx >/dev/stderr
Note most csh are really tcsh in modern environments:
rmockler> ls -latr /usr/bin/csh
lrwxrwxrwx 1 root root 9 2011-05-03 13:40 /usr/bin/csh -> /bin/tcsh
using a backtick embedded statement to portray this as follows:
echo "`echo 'standard out1'` `echo 'error out1' >/dev/stderr` `echo 'standard out2'`" | tee -a /tmp/test.txt ; cat /tmp/test.txt
if this works for you please bump up to 1. The other suggestions don't work for my csh environment.

So many answers and still everybody forgot about the strangely named, oddly behaved, and yet still handy dict.setdefault()
This
value = my_dict.setdefault(key, default)
basically just does this:
try:
value = my_dict[key]
except KeyError: # key not found
value = my_dict[key] = default
e.g.
>>> mydict = {'a':1, 'b':2, 'c':3}
>>> mydict.setdefault('d', 4)
4 # returns new value at mydict['d']
>>> print(mydict)
{'a':1, 'b':2, 'c':3, 'd':4} # a new key/value pair was indeed added
# but see what happens when trying it on an existing key...
>>> mydict.setdefault('a', 111)
1 # old value was returned
>>> print(mydict)
{'a':1, 'b':2, 'c':3, 'd':4} # existing key was ignored

Quick answer
On src, you can always specify files to ignore using "!".
Example (you want to exclude all *.min.js files on your js folder and subfolder:
gulp.src(['js/**/*.js', '!js/**/*.min.js'])
You can do it as well for individual files.
Expanded answer:
Extracted from gulp documentation:
gulp.src(globs[, options])
Emits files matching provided glob or an array of globs. Returns a stream of Vinyl files that can be piped to plugins.
glob refers to node-glob syntax or it can be a direct file path.
So, looking to node-glob documentation we can see that it uses the minimatch library to do its matching.
On minimatch documentation, they point out the following:
if the pattern starts with a ! character, then it is negated.
And that is why using ! symbol will exclude files / directories from a gulp task
If somehow you want a simple, yet different solution, you can use the {**dict}
syntax:
from collections import OrderedDict
ordered = OrderedDict([('method', 'constant'), ('data', '1.225')])
regular = {**ordered}
You say your website is in http://localhost/mywebsite
, and let's say that your image is inside a subfolder named pictures/
:
Absolute path
If you use an absolute path, /
would point to the root of the site, not the root of the document: localhost
in your case. That's why you need to specify your document's folder in order to access the pictures folder:
"/mywebsite/pictures/picture.png"
And it would be the same as:
"http://localhost/mywebsite/pictures/picture.png"
Relative path
A relative path is always relative to the root of the document, so if your html is at the same level of the directory, you'd need to start the path directly with your picture's directory name:
"pictures/picture.png"
But there are other perks with relative paths:
dot-slash (./
)
Dot (.
) points to the same directory and the slash (/
) gives access to it:
So this:
"pictures/picture.png"
Would be the same as this:
"./pictures/picture.png"
Double-dot-slash (../
)
In this case, a double dot (..
) points to the upper directory and likewise, the slash (/
) gives you access to it. So if you wanted to access a picture that is on a directory one level above of the current directory your document is, your URL would look like this:
"../picture.png"
You can play around with them as much as you want, a little example would be this:
Let's say you're on directory A
, and you want to access directory X
.
- root
|- a
|- A
|- b
|- x
|- X
Your URL would look either:
Absolute path
"/x/X/picture.png"
Or:
Relative path
"./../x/X/picture.png"
I found the reason why the connection was not working, it was because the connection was trying to connect to port 8888, when it needed to connect to port 8889.
$conn = new PDO("mysql:host=$servername;port=8889;dbname=AppDatabase", $username, $password);
This fixed the problem, although changing the server name to localhost still gives the error.
Connection failed: SQLSTATE[HY000] [2002] No such file or directory
But it connects successfully when the IP address is entered for the server name.
Here's a variant that lets you use a regex pattern for initial filtering, change the regex to be get the filtering you desire.
files=($(find -E . -type f -regex "^.*$"))
for item in ${files[*]}
do
printf " %s\n" $item
done
Open your page in Firefox and get the HTTPFox addon. It will tell you all that you need.
Found this on archivist.incuito:
http://archivist.incutio.com/viewlist/css-discuss/76444
When you first request a page, your browser sends a GET request to the server, which returns the HTML to the browser. The browser then starts parsing the page (possibly before all of it has been returned).
When it finds a reference to an external entity such as a CSS file, an image file, a script file, a Flash file, or anything else external to the page (either on the same server/domain or not), it prepares to make a further GET request for that resource.
However the HTTP standard specifies that the browser should not make more than two concurrent requests to the same domain. So it puts each request to a particular domain in a queue, and as each entity is returned it starts the next one in the queue for that domain.
The time it takes for an entity to be returned depends on its size, the load the server is currently experiencing, and the activity of every single machine between the machine running the browser and the server. The list of these machines can in principle be different for every request, to the extent that one image might travel from the USA to me in the UK over the Atlantic, while another from the same server comes out via the Pacific, Asia and Europe, which takes longer. So you might get a sequence like the following, where a page has (in this order) references to three script files, and five image files, all of differing sizes:
- GET script1 and script2; queue request for script3 and images1-5.
- script2 arrives (it's smaller than script1): GET script3, queue images1-5.
- script1 arrives; GET image1, queue images2-5.
- image1 arrives, GET image2, queue images3-5.
- script3 fails to arrive due to a network problem - GET script3 again (automatic retry).
- image2 arrives, script3 still not here; GET image3, queue images4-5.
- image 3 arrives; GET image4, queue image5, script3 still on the way.
- image4 arrives, GET image5;
- image5 arrives.
- script3 arrives.
In short: any old order, depending on what the server is doing, what the rest of the Internet is doing, and whether or not anything has errors and has to be re-fetched. This may seem like a weird way of doing things, but it would quite literally be impossible for the Internet (not just the WWW) to work with any degree of reliability if it wasn't done this way.
Also, the browser's internal queue might not fetch entities in the order they appear in the page - it's not required to by any standard.
(Oh, and don't forget caching, both in the browser and in caching proxies used by ISPs to ease the load on the network.)
WPF has built-in converters for certain types. If you bind the Image's Source
property to a string
or Uri
value, under the hood WPF will use an ImageSourceConverter to convert the value to an ImageSource
.
So
<Image Source="{Binding ImageSource}"/>
would work if the ImageSource property was a string representation of a valid URI to an image.
You can of course roll your own Binding converter:
public class ImageConverter : IValueConverter
{
public object Convert(
object value, Type targetType, object parameter, CultureInfo culture)
{
return new BitmapImage(new Uri(value.ToString()));
}
public object ConvertBack(
object value, Type targetType, object parameter, CultureInfo culture)
{
throw new NotSupportedException();
}
}
and use it like this:
<Image Source="{Binding ImageSource, Converter={StaticResource ImageConverter}}"/>
Similarly using Bash regexp. Shall be able to snatch any key/value pair.
key="Body"
re="\"($key)\": \"([^\"]*)\""
while read -r l; do
if [[ $l =~ $re ]]; then
name="${BASH_REMATCH[1]}"
value="${BASH_REMATCH[2]}"
echo "$name=$value"
else
echo "No match"
fi
done
Regular expression can be tuned to match multiple spaces/tabs or newline(s). Wouldn't work if value has embedded "
. This is an illustration. Better to use some "industrial" parser :)
About the extra space at the bottom: is your page an ASP.NET application? If so, there is probably a wrapping almost everything in your markup. Don't forget to style the form as well. Adding overflow:hidden;
to the form might remove the extra space at the bottom.
Note that namespaces that are in the format of a valid Web URL don't necessarily need to be dereferenced i.e. you don't need to serve actual content at that URL. All that matters is that the namespace is globally unique.

There are various methods available in Rust to concatenate strings
concat!()
):fn main() {
println!("{}", concat!("a", "b"))
}
The output of the above code is :
ab
push_str()
and +
operator):fn main() {
let mut _a = "a".to_string();
let _b = "b".to_string();
let _c = "c".to_string();
_a.push_str(&_b);
println!("{}", _a);
println!("{}", _a + &_c);
}
The output of the above code is:
ab
abc
Using format!()
):fn main() {
let mut _a = "a".to_string();
let _b = "b".to_string();
let _c = format!("{}{}", _a, _b);
println!("{}", _c);
}
The output of the above code is :

Actually, all of those examples on the web wherein the common content/file type like "js", "css", "img", etc is been used as library name are misleading.
To start, let's look at how existing JSF implementations like Mojarra and MyFaces and JSF component libraries like PrimeFaces and OmniFaces use it. No one of them use resource libraries this way. They use it (under the covers, by @ResourceDependency
or UIViewRoot#addComponentResource()
) the following way:
<h:outputScript library="javax.faces" name="jsf.js" />
<h:outputScript library="primefaces" name="jquery/jquery.js" />
<h:outputScript library="omnifaces" name="omnifaces.js" />
<h:outputScript library="omnifaces" name="fixviewstate.js" />
<h:outputScript library="omnifaces.combined" name="[dynamicname].js" />
<h:outputStylesheet library="primefaces" name="primefaces.css" />
<h:outputStylesheet library="primefaces-aristo" name="theme.css" />
<h:outputStylesheet library="primefaces-vader" name="theme.css" />
It should become clear that it basically represents the common library/module/theme name where all of those resources commonly belong to.
This way it's so much easier to specify and distinguish where those resources belong to and/or are coming from. Imagine that you happen to have a primefaces.css
resource in your own webapp wherein you're overriding/finetuning some default CSS of PrimeFaces; if PrimeFaces didn't use a library name for its own primefaces.css
, then the PrimeFaces own one wouldn't be loaded, but instead the webapp-supplied one, which would break the look'n'feel.
Also, when you're using a custom ResourceHandler
, you can also apply more finer grained control over resources coming from a specific library when library
is used the right way. If all component libraries would have used "js" for all their JS files, how would the ResourceHandler
ever distinguish if it's coming from a specific component library? Examples are OmniFaces CombinedResourceHandler
and GraphicResourceHandler
; check the createResource()
method wherein the library is checked before delegating to next resource handler in chain. This way they know when to create CombinedResource
or GraphicResource
for the purpose.
Noted should be that RichFaces did it wrong. It didn't use any library
at all and homebrewed another resource handling layer over it and it's therefore impossible to programmatically identify RichFaces resources. That's exactly the reason why OmniFaces CombinedResourceHander
had to introduce a reflection-based hack in order to get it to work anyway with RichFaces resources.
Your own webapp does not necessarily need a resource library. You'd best just omit it.
<h:outputStylesheet name="css/style.css" />
<h:outputScript name="js/script.js" />
<h:graphicImage name="img/logo.png" />
Or, if you really need to have one, you can just give it a more sensible common name, like "default" or some company name.
<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />
Or, when the resources are specific to some master Facelets template, you could also give it the name of the template, so that it's easier to relate each other. In other words, it's more for self-documentary purposes. E.g. in a /WEB-INF/templates/layout.xhtml
template file:
<h:outputStylesheet library="layout" name="css/style.css" />
<h:outputScript library="layout" name="js/script.js" />
And a /WEB-INF/templates/admin.xhtml
template file:
<h:outputStylesheet library="admin" name="css/style.css" />
<h:outputScript library="admin" name="js/script.js" />
For a real world example, check the OmniFaces showcase source code.
Or, when you'd like to share the same resources over multiple webapps and have created a "common" project for that based on the same example as in this answer which is in turn embedded as JAR in webapp's /WEB-INF/lib
, then also reference it as library (name is free to your choice; component libraries like OmniFaces and PrimeFaces also work that way):
<h:outputStylesheet library="common" name="css/style.css" />
<h:outputScript library="common" name="js/script.js" />
<h:graphicImage library="common" name="img/logo.png" />
Another main advantage is that you can apply resource library versioning the right way on resources provided by your own webapp (this doesn't work for resources embedded in a JAR). You can create a direct child subfolder in the library folder with a name in the \d+(_\d+)*
pattern to denote the resource library version.
WebContent
|-- resources
| `-- default
| `-- 1_0
| |-- css
| | `-- style.css
| |-- img
| | `-- logo.png
| `-- js
| `-- script.js
:
When using this markup:
<h:outputStylesheet library="default" name="css/style.css" />
<h:outputScript library="default" name="js/script.js" />
<h:graphicImage library="default" name="img/logo.png" />
This will generate the following HTML with the library version as v
parameter:
<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&v=1_0" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&v=1_0"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&v=1_0" alt="" />
So, if you have edited/updated some resource, then all you need to do is to copy or rename the version folder into a new value. If you have multiple version folders, then the JSF ResourceHandler
will automatically serve the resource from the highest version number, according to numerical ordering rules.
So, when copying/renaming resources/default/1_0/*
folder into resources/default/1_1/*
like follows:
WebContent
|-- resources
| `-- default
| |-- 1_0
| | :
| |
| `-- 1_1
| |-- css
| | `-- style.css
| |-- img
| | `-- logo.png
| `-- js
| `-- script.js
:
Then the last markup example would generate the following HTML:
<link rel="stylesheet" type="text/css" href="/contextname/javax.faces.resource/css/style.css.xhtml?ln=default&v=1_1" />
<script type="text/javascript" src="/contextname/javax.faces.resource/js/script.js.xhtml?ln=default&v=1_1"></script>
<img src="/contextname/javax.faces.resource/img/logo.png.xhtml?ln=default&v=1_1" alt="" />
This will force the webbrowser to request the resource straight from the server instead of showing the one with the same name from the cache, when the URL with the changed parameter is been requested for the first time. This way the endusers aren't required to do a hard refresh (Ctrl+F5 and so on) when they need to retrieve the updated CSS/JS resource.
Please note that library versioning is not possible for resources enclosed in a JAR file. You'd need a custom ResourceHandler
. See also How to use JSF versioning for resources in jar.
For MySQL Workbench 8.0 navigate to:
Server > Data Import
A new tab called Administration - Data Import/Restore appears. There you can choose to import a Dump Project Folder or use a specific SQL file according to your needs. Then you must select a schema where the data will be imported to, or you have to click the New... button to type a name for the new schema.
Then you can select the database objects to be imported or just click the Start Import button in the lower right part of the tab area.
Having done that and if the import was successful, you'll need to update the Schema Navigator by clicking the arrow circle icon.
That's it!

First of all, you can't prevent people from downloading fonts except if it is yours and that usually takes months. And it makes no sense to prevent people from using fonts. A lot of fonts that you see on websites can be found on free platforms like the one I mentioned below.
But if you want to implement a font into your website read this: There is a pretty simple and free way to implement fonts into your website. I would recommend Google fonts because it is free and easy to use. For example, I'll use the Bangers font from Google.(https://fonts.google.com/specimen/Bangers?query=bangers&sidebar.open&selection.family=Bangers) This is how it would look like: HTML
<head>
<link href="https://fonts.googleapis.com/css2?family=Bangers&display=swap" rel="stylesheet">
</head>
CSS
body {
font-family: 'Bangers', cursive;
}
Just reading the file into an array, one line per element, is trivial:
open my $handle, '<', $path_to_file;
chomp(my @lines = <$handle>);
close $handle;
Now the lines of the file are in the array @lines
.
If you want to make sure there is error handling for open
and close
, do something like this (in the snipped below, we open the file in UTF-8 mode, too):
my $handle;
unless (open $handle, "<:encoding(utf8)", $path_to_file) {
print STDERR "Could not open file '$path_to_file': $!\n";
# we return 'undefined', we could also 'die' or 'croak'
return undef
}
chomp(my @lines = <$handle>);
unless (close $handle) {
# what does it mean if close yields an error and you are just reading?
print STDERR "Don't care error while closing '$path_to_file': $!\n";
}
for switch to another page, try with this code:
viewPager.postDelayed(new Runnable()
{
@Override
public void run()
{
viewPager.setCurrentItem(num, true);
}
}, 100);
It should be as simple as using a list of receiving variables:
scanf("%i %i %i", &var1, &var2, &var3);
Press A to enter edit mode starting at the end of the line.
Use setInverseBackgroundForced(true)
on the alert dialog builder to invert the background.
I fixed an error like this changing the places of the routes in routes.php, for example i had something like this:
Route::resource('Mensajes', 'MensajeriaController');
Route::get('Mensajes/modificar', 'MensajeriaController@modificarEstado');
and then I put it like this:
Route::get('Mensajes/modificar', 'MensajeriaController@modificarEstado');
Route::resource('Mensajes', 'MensajeriaController');
If you put
window.location.reload(true);
at the beginning of your page with no other condition qualifying why that code runs, the page will load and then continue to reload itself until you close your browser.
I was also facing the same problem a few minutes before when I tried to run a flutter project in my C/(.something../.something../.something../.something....)

you can have a variable
DEBUG = 0
then you can use a conditional statement
ifeq ($(DEBUG),1)
else

The general rule-of-thumb is, if you can do it using a single SQL statement instead of using PL/SQL, you should. It will usually be more efficient.
However, if you need to add more procedural logic (for some reason), you might need to use PL/SQL, but you should use bulk operations instead of row-by-row processing. (Note: in Oracle 10g and later, your FOR loop will automatically use BULK COLLECT to fetch 100 rows at a time; however your insert statement will still be done row-by-row).
e.g.
DECLARE
TYPE tA IS TABLE OF FOO.A%TYPE INDEX BY PLS_INTEGER;
TYPE tB IS TABLE OF FOO.B%TYPE INDEX BY PLS_INTEGER;
TYPE tC IS TABLE OF FOO.C%TYPE INDEX BY PLS_INTEGER;
rA tA;
rB tB;
rC tC;
BEGIN
SELECT * BULK COLLECT INTO rA, rB, rC FROM FOO;
-- (do some procedural logic on the data?)
FORALL i IN rA.FIRST..rA.LAST
INSERT INTO BAR(A,
B,
C)
VALUES(rA(i),
rB(i),
rC(i));
END;
The above has the benefit of minimising context switches between SQL and PL/SQL. Oracle 11g also has better support for tables of records so that you don't have to have a separate PL/SQL table for each column.
Also, if the volume of data is very great, it is possible to change the code to process the data in batches.
If your grid is bound to a DataTable
, I believe you can just do:
// Should probably add a DBNull check for safety; but you get the idea.
long sum = (long)table.Compute("Sum(count)", "True");
If it isn't bound to a table, you could easily make it so:
var table = new DataTable();
table.Columns.Add("type", typeof(string));
table.Columns.Add("count", typeof(int));
// This will automatically create the DataGridView's columns.
dataGridView.DataSource = table;
To return the client side date you can use the following javascript:
var d = new Date();
var month = d.getMonth()+1;
var date = d.getDate()+"."+month+"."+d.getFullYear();
document.getElementById('date').innerHTML = date;
or in jQuery:
var d = new Date();
var month = d.getMonth()+1;
var date = d.getDate()+"."+month+"."+d.getFullYear();
$('#date').html(date);
equivalent to following PHP:
<?php date("j.n.Y"); ?>
To get equivalent to the following PHP (i.e. leading 0's):
<?php date("d.m.Y"); ?>
JavaScript:
var d = new Date();
var day = d.getDate();
var month = d.getMonth()+1;
if(day < 10){
day = "0"+d.getDate();
}
if(month < 10){
month = "0"+eval(d.getMonth()+1);
}
var date = day+"."+month+"."+d.getFullYear();
document.getElementById('date').innerHTML = date;
jQuery:
var d = new Date();
var day = d.getDate();
var month = d.getMonth()+1;
if(day < 10){
day = "0"+d.getDate();
}
if(month < 10){
month = "0"+eval(d.getMonth()+1);
}
var date = day+"."+month+"."+d.getFullYear();
$('#date').html(date);
I just managed to make it work again. It makes not much sense but it worked:
I'll investigate further later but the method I called with hangfire receives a DBContext and that is the possible cause.
I've had this problem after installing the genymotion (another android amulator) plugin. A closer inspection reveled that gradle needs SDK tools version 19.1.0 in order to run (I had 19.0.3 previously).
To fix it, I had to edit build.gradle
and under android
I changed to: buildToolsVersion 19.1.0
Then I had to rebuild again, and the error was gone.
If you want to delete all files whose names match a particular form, a wildcard (glob pattern) is the most straightforward solution. Some examples:
$ rm -f abc.log.* # Remove them all
$ rm -f abc.log.2012* # Remove all logs from 2012
$ rm -f abc.log.2012-0[123]* # Remove all files from the first quarter of 2012
Regular expressions are more powerful than wildcards; you can feed the output of grep
to rm -f
. For example, if some of the file names start with "abc.log"
and some with "ABC.log"
, grep
lets you do a case-insensitive match:
$ rm -f $(ls | grep -i '^abc\.log\.')
This will cause problems if any of the file names contain funny characters, including spaces. Be careful.
When I do this, I run the ls | grep ...
command first and check that it produces the output I want -- especially if I'm using rm -f
:
$ ls | grep -i '^abc\.log\.'
(check that the list is correct)
$ rm -f $(!!)
where !!
expands to the previous command. Or I can type up-arrow or Ctrl-P and edit the previous line to add the rm -f
command.
This assumes you're using the bash shell. Some other shells, particularly csh and tcsh and some older sh-derived shells, may not support the $(...)
syntax. You can use the equivalent backtick syntax:
$ rm -f `ls | grep -i '^abc\.log\.'`
The $(...)
syntax is easier to read, and if you're really ambitious it can be nested.
Finally, if the subset of files you want to delete can't be easily expressed with a regular expression, a trick I often use is to list the files to a temporary text file, then edit it:
$ ls > list
$ vi list # Use your favorite text editor
I can then edit the list
file manually, leaving only the files I want to remove, and then:
$ rm -f $(<list)
or
$ rm -f `cat list`
(Again, this assumes none of the file names contain funny characters, particularly spaces.)
Or, when editing the list
file, I can add rm -f
to the beginning of each line and then:
$ . ./list
or
$ source ./list
Editing the file is also an opportunity to add quotes where necessary, for example changing rm -f foo bar
to rm -f 'foo bar'
.
Or you could have done this:
select trunc(sysdate) - to_date('2009-10-01', 'yyyy-mm-dd') from dual
This returns a NUMBER of whole days:
SQL> create view v as
2 select trunc(sysdate) - to_date('2009-10-01', 'yyyy-mm-dd') diff
3 from dual;
View created.
SQL> select * from v;

I know the question specifies Excel, but since the same question for Access got marked as duplicate, so I will post my answer here. The principle is simple: open a new Access application, then open a form with a timer inside that application, send the function/sub you want to execute to that form, execute the task if the timer hits, and quit the application once execution has finished. This allows the VBA to work with tables and queries from your database. Note: it will throw errors if you've exclusively locked the database.
This is all VBA (as opposed to other answers)
The function that runs a sub/function asynchronously
Public Sub RunFunctionAsync(FunctionName As String)
Dim A As Access.Application
Set A = New Access.Application
A.OpenCurrentDatabase Application.CurrentProject.FullName
A.DoCmd.OpenForm "MultithreadingEngine"
With A.Forms("MultiThreadingEngine")
.TimerInterval = 10
.AddToTaskCollection (FunctionName)
End With
End Sub
The module of the form required to achieve this
(form name = MultiThreadingEngine, doesn't have any controls or properties set)
Public TaskCollection As Collection
Public Sub AddToTaskCollection(str As String)
If TaskCollection Is Nothing Then
Set TaskCollection = New Collection
End If
TaskCollection.Add str
End Sub
Private Sub Form_Timer()
If Not TaskCollection Is Nothing Then
If TaskCollection.Count <> 0 Then
Dim CollectionItem As Variant
For Each CollectionItem In TaskCollection
Run CollectionItem
Next CollectionItem
End If
End If
Application.Quit
End Sub
Implementing support for parameters should be easy enough, returning values is difficult, however.
Comparison of execution time of bubble sort and selection sort I have a program which compares the execution time of bubble sort and selection sort. To find out the time of execution of a block of code compute the time before and after the block by
clock_t start=clock();
…
clock_t end=clock();
CLOCKS_PER_SEC is constant in time.h library
Example code:
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
int main()
{
int a[10000],i,j,min,temp;
for(i=0;i<10000;i++)
{
a[i]=rand()%10000;
}
//The bubble Sort
clock_t start,end;
start=clock();
for(i=0;i<10000;i++)
{
for(j=i+1;j<10000;j++)
{
if(a[i]>a[j])
{
int temp=a[i];
a[i]=a[j];
a[j]=temp;
}
}
}
end=clock();
double extime=(double) (end-start)/CLOCKS_PER_SEC;
printf("\n\tExecution time for the bubble sort is %f seconds\n ",extime);
for(i=0;i<10000;i++)
{
a[i]=rand()%10000;
}
clock_t start1,end1;
start1=clock();
// The Selection Sort
for(i=0;i<10000;i++)
{
min=i;
for(j=i+1;j<10000;j++)
{
if(a[min]>a[j])
{
min=j;
}
}
temp=a[min];
a[min]=a[i];
a[i]=temp;
}
end1=clock();
double extime1=(double) (end1-start1)/CLOCKS_PER_SEC;
printf("\n");
printf("\tExecution time for the selection sort is %f seconds\n\n", extime1);
if(extime1<extime)
printf("\tSelection sort is faster than Bubble sort by %f seconds\n\n", extime - extime1);
else if(extime1>extime)
printf("\tBubble sort is faster than Selection sort by %f seconds\n\n", extime1 - extime);
else
printf("\tBoth algorithms have the same execution time\n\n");
}
You can't have two Content-Type
s (well technically that's what we're doing below, but they are separated with each part of the multipart, but the main type is multipart). That's basically what you are expecting with your method. You are expecting mutlipart and json together as the main media type. The Employee
data needs to be part of the multipart. So you can add a @FormDataParam("emp")
for the Employee
.
@FormDataParam("emp") Employee emp) { ...
Here's the class I used for testing
@Path("/multipart")
public class MultipartResource {
@POST
@Path("/upload2")
@Consumes({MediaType.MULTIPART_FORM_DATA})
public Response uploadFileWithData(
@FormDataParam("file") InputStream fileInputStream,
@FormDataParam("file") FormDataContentDisposition cdh,
@FormDataParam("emp") Employee emp) throws Exception{
Image img = ImageIO.read(fileInputStream);
JOptionPane.showMessageDialog(null, new JLabel(new ImageIcon(img)));
System.out.println(cdh.getName());
System.out.println(emp);
return Response.ok("Cool Tools!").build();
}
}
First I just tested with the client API to make sure it works
@Test
public void testGetIt() throws Exception {
final Client client = ClientBuilder.newBuilder()
.register(MultiPartFeature.class)
.build();
WebTarget t = client.target(Main.BASE_URI).path("multipart").path("upload2");
FileDataBodyPart filePart = new FileDataBodyPart("file",
new File("stackoverflow.png"));
// UPDATE: just tested again, and the below code is not needed.
// It's redundant. Using the FileDataBodyPart already sets the
// Content-Disposition information
filePart.setContentDisposition(
FormDataContentDisposition.name("file")
.fileName("stackoverflow.png").build());
String empPartJson
= "{"
+ " \"id\": 1234,"
+ " \"name\": \"Peeskillet\""
+ "}";
MultiPart multipartEntity = new FormDataMultiPart()
.field("emp", empPartJson, MediaType.APPLICATION_JSON_TYPE)
.bodyPart(filePart);
Response response = t.request().post(
Entity.entity(multipartEntity, multipartEntity.getMediaType()));
System.out.println(response.getStatus());
System.out.println(response.readEntity(String.class));
response.close();
}
I just created a simple Employee
class with an id
and name
field for testing. This works perfectly fine. It shows the image, prints the content disposition, and prints the Employee
object.
I'm not too familiar with Postman, so I saved that testing for last :-)
It appears to work fine also, as you can see the response "Cool Tools"
. But if we look at the printed Employee
data, we'll see that it's null. Which is weird because with the client API it worked fine.
If we look at the Preview window, we'll see the problem
There's no Content-Type
header for the emp
body part. You can see in the client API I explicitly set it
MultiPart multipartEntity = new FormDataMultiPart()
.field("emp", empPartJson, MediaType.APPLICATION_JSON_TYPE)
.bodyPart(filePart);
So I guess this is really only part of a full answer. Like I said, I am not familiar with Postman So I don't know how to set Content-Type
s for individual body parts. The image/png
for the image was automatically set for me for the image part (I guess it was just determined by the file extension). If you can figure this out, then the problem should be solved. Please, if you find out how to do this, post it as an answer.
See UPDATE below for solution
Basic configurations:
Dependency:
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-multipart</artifactId>
<version>${jersey2.version}</version>
</dependency>
Client config:
final Client client = ClientBuilder.newBuilder()
.register(MultiPartFeature.class)
.build();
Server config:
// Create JAX-RS application.
final Application application = new ResourceConfig()
.packages("org.glassfish.jersey.examples.multipart")
.register(MultiPartFeature.class);
If you're having problems with the server configuration, one of the following posts might help
So as you can see from the Postman client, some clients are unable to set individual parts' Content-Type, this includes the browser, in regards to it's default capabilities when using FormData
(js).
We can't expect the client to find away around this, so what we can do, is when receiving the data, explicitly set the Content-Type before deserializing. For example
@POST
@Path("upload2")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFileAndJSON(@FormDataParam("emp") FormDataBodyPart jsonPart,
@FormDataParam("file") FormDataBodyPart bodyPart) {
jsonPart.setMediaType(MediaType.APPLICATION_JSON_TYPE);
Employee emp = jsonPart.getValueAs(Employee.class);
}
It's a little extra work to get the POJO, but it is a better solution than forcing the client to try and find it's own solution.
Another option is to use a String parameter and use whatever JSON library you use to deserialze the String to the POJO (like Jackson ObjectMapper). With the previous option, we just let Jersey handle the deserialization, and it will use the same JSON library it uses for all the other JSON endpoints (which might be preferred).
When Excel finds mixed data types in same column it guesses what is the right format for the column (the majority of the values determines the type of the column) and dismisses all other values by inserting NULLs. But Excel does it far badly (e.g. if a column is considered text and Excel finds a number then decides that the number is a mistake and insert a NULL instead, or if some cells containing numbers are "text" formatted, one may get NULL values into an integer column of the database).
Solution:
Note that formatting the columns on an existing Excel sheet is not enough.
I would use this syntax to set the index value into an attribute of the HTML element:
You have to use let
to declare the value rather than #
.
<ul>
<li *ngFor="let item of items; let i = index" [attr.data-index]="i">
{{item}}
</li>
</ul>
<ul>
<li *ngFor="#item of items; #i = index" [attr.data-index]="i">
{{item}}
</li>
</ul>
Here is the updated plunkr: http://plnkr.co/edit/LiCeyKGUapS5JKkRWnUJ?p=preview.
The following checklink.cmd
program is a good place to start. It relies on the fact that you can do a single-shot ping and that, if successful, the output will contain the line:
Packets: Sent = 1, Received = 1, Lost = 0 (0% loss),
By extracting tokens 5 and 7 and checking they're respectively "Received"
and "1,"
, you can detect the success.
@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
:loop
set state=down
for /f "tokens=5,6,7" %%a in ('ping -n 1 !ipaddr!') do (
if "x%%b"=="xunreachable." goto :endloop
if "x%%a"=="xReceived" if "x%%c"=="x1," set state=up
)
:endloop
echo.Link is !state!
ping -n 6 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal
Call it with the name (or IP address) you want to test:
checklink 127.0.0.1
checklink localhost
checklink nosuchaddress
Take into account that, if your locale is not English, you must replace Received
with the corresponding keyword in your locale, for example recibidos
for Spanish. Do a test ping to discover what keyword is used in your locale.
To only notify you when the state changes, you can use:
@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
set oldstate=neither
:loop
set state=down
for /f "tokens=5,7" %%a in ('ping -n 1 !ipaddr!') do (
if "x%%a"=="xReceived" if "x%%b"=="x1," set state=up
)
if not !state!==!oldstate! (
echo.Link is !state!
set oldstate=!state!
)
ping -n 2 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal
However, as Gabe points out in a comment, you can just use ERRORLEVEL
so the equivalent of that second script above becomes:
@setlocal enableextensions enabledelayedexpansion
@echo off
set ipaddr=%1
set oldstate=neither
:loop
set state=up
ping -n 1 !ipaddr! >nul: 2>nul:
if not !errorlevel!==0 set state=down
if not !state!==!oldstate! (
echo.Link is !state!
set oldstate=!state!
)
ping -n 2 127.0.0.1 >nul: 2>nul:
goto :loop
endlocal
You can write your own jQuery plugins(function which can be called on selected elements) like below:
(function( $ ){ $.fn.myFunc = function(param1, param2){ //this - jquery object holds your selected elements } })( jQuery );
Call it later like:
$('div').myFunc(1, null);
if you know the index of the item of default value,just
lstDepartment.SelectedIndex = 1;//the second item
or if you know the value you want to set, just
lstDepartment.SelectedValue = "the value you want to set";
The easiest/best supported method is to use <table cellspacing="10">
The css way: border-spacing (not supported by IE I don't think)
<!-- works in firefox, opera, safari, chrome -->_x000D_
<style type="text/css">_x000D_
_x000D_
table.foobar {_x000D_
border: solid black 1px;_x000D_
border-spacing: 10px;_x000D_
}_x000D_
table.foobar td {_x000D_
border: solid black 1px;_x000D_
}_x000D_
_x000D_
_x000D_
</style>_x000D_
_x000D_
<table class="foobar" cellpadding="0" cellspacing="0">_x000D_
<tr><td>foo</td><td>bar</td></tr>_x000D_
</table>
_x000D_
Edit: if you just want to pad the cell content, and not space them you can simply use
<table cellpadding="10">
OR
td {
padding: 10px;
}
Running commands as Super Admin worked for me. Retry after closing Editor your are working in.
If you have a ConstraintLayout
with some size, and a child View
with some smaller size, you can achieve centering by constraining the child's two edges to the same two edges of the parent. That is, you can write:
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
or
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
Because the view is smaller, these constraints are impossible. But ConstraintLayout
will do the best it can, and each constraint will "pull" at the child view equally, thereby centering it.
This concept works with any target view, not just the parent.
Below is XML that achieves your desired UI with no nesting of views and no Guideline
s (though guidelines are not inherently evil).

As iEamin said in his answer, HTML 5 does now support this. The link he gave, http://www.html5rocks.com/en/tutorials/file/dndfiles/ , is excellent. Here is a minimal sample based on the samples at that site, but see that site for more thorough examples.
Add an onchange
event listener to your HTML:
<input type="file" onchange="onFileSelected(event)">
Make an image tag with an id (I'm specifying height=200
to make sure the image isn't too huge onscreen):
<img id="myimage" height="200">
Here is the JavaScript of the onchange
event listener. It takes the File
object that was passed as event.target.files[0]
, constructs a FileReader
to read its contents, and sets up a new event listener to assign the resulting data:
URL to the img
tag:
function onFileSelected(event) {
var selectedFile = event.target.files[0];
var reader = new FileReader();
var imgtag = document.getElementById("myimage");
imgtag.title = selectedFile.name;
reader.onload = function(event) {
imgtag.src = event.target.result;
};
reader.readAsDataURL(selectedFile);
}
You need a dependency property for this:
public BindingList<User> Users
{
get { return (BindingList<User>)GetValue(UsersProperty); }
set { SetValue(UsersProperty, value); }
}
public static readonly DependencyProperty UsersProperty =
DependencyProperty.Register("Users", typeof(BindingList<User>),
typeof(OptionsDialog));
Once that is done, you bind the checkbox to the dependency property:
<CheckBox x:Name="myCheckBox"
IsChecked="{Binding ElementName=window1, Path=CheckBoxIsChecked}" />
For that to work you have to name your Window or UserControl in its openning tag, and use that name in the ElementName parameter.
With this code, whenever you change the property on the code side, you will change the textbox. Also, whenever you check/uncheck the textbox, the Dependency Property will change too.
EDIT:
An easy way to create a dependency property is typing the snippet propdp, which will give you the general code for Dependency Properties.
All the code:
XAML:
<Window x:Class="StackOverflowTests.Window1"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="Window1" x:Name="window1" Height="300" Width="300">
<Grid>
<StackPanel Orientation="Vertical">
<CheckBox Margin="10"
x:Name="myCheckBox"
IsChecked="{Binding ElementName=window1, Path=IsCheckBoxChecked}">
Bound CheckBox
</CheckBox>
<Label Content="{Binding ElementName=window1, Path=IsCheckBoxChecked}"
ContentStringFormat="Is checkbox checked? {0}" />
</StackPanel>
</Grid>
</Window>
C#:
using System.Windows;
namespace StackOverflowTests
{
/// <summary>
/// Interaction logic for Window1.xaml
/// </summary>
public partial class Window1 : Window
{
public bool IsCheckBoxChecked
{
get { return (bool)GetValue(IsCheckBoxCheckedProperty); }
set { SetValue(IsCheckBoxCheckedProperty, value); }
}
// Using a DependencyProperty as the backing store for
//IsCheckBoxChecked. This enables animation, styling, binding, etc...
public static readonly DependencyProperty IsCheckBoxCheckedProperty =
DependencyProperty.Register("IsCheckBoxChecked", typeof(bool),
typeof(Window1), new UIPropertyMetadata(false));
public Window1()
{
InitializeComponent();
}
}
}
Notice how the only code behind is the Dependency Property. Both the label and the checkbox are bound to it. If the checkbox changes, the label changes too.
Simple solution:
document.getElementById("upload-files").value = "";
Escape sequences must be interpreted by SOMETHING to be converted to color. The standard CMD.EXE used by java when started from the command line, doesn't support this so therefore Java does not.
You could use feature detection to see if browser is IE10 or greater like so:
var isIE = false;
if (window.navigator.msPointerEnabled) {
isIE = true;
}
Only true if > IE9
I had the same error because I switched from XML- to java-configuration.
The point was, I didn't migrate <tx:annotation-driven/>
tag, as Stone Feng suggested.
So I just added @EnableTransactionManagement
as suggested here
Setting Up Annotation Driven Transactions in Spring in @Configuration Class, and it works now
To give the simplest answer I can think of:
Suppose we have a problem that takes a certain number of inputs, and has various potential solutions, which may or may not solve the problem for given inputs. A logic puzzle in a puzzle magazine would be a good example: the inputs are the conditions ("George doesn't live in the blue or green house"), and the potential solution is a list of statements ("George lives in the yellow house, grows peas, and owns the dog"). A famous example is the Traveling Salesman problem: given a list of cities, and the times to get from any city to any other, and a time limit, a potential solution would be a list of cities in the order the salesman visits them, and it would work if the sum of the travel times was less than the time limit.
Such a problem is in NP if we can efficiently check a potential solution to see if it works. For example, given a list of cities for the salesman to visit in order, we can add up the times for each trip between cities, and easily see if it's under the time limit. A problem is in P if we can efficiently find a solution if one exists.
(Efficiently, here, has a precise mathematical meaning. Practically, it means that large problems aren't unreasonably difficult to solve. When searching for a possible solution, an inefficient way would be to list all possible potential solutions, or something close to that, while an efficient way would require searching a much more limited set.)
Therefore, the P=NP problem can be expressed this way: If you can verify a solution for a problem of the sort described above efficiently, can you find a solution (or prove there is none) efficiently? The obvious answer is "Why should you be able to?", and that's pretty much where the matter stands today. Nobody has been able to prove it one way or another, and that bothers a lot of mathematicians and computer scientists. That's why anybody who can prove the solution is up for a million dollars from the Claypool Foundation.
We generally assume that P does not equal NP, that there is no general way to find solutions. If it turned out that P=NP, a lot of things would change. For example, cryptography would become impossible, and with it any sort of privacy or verifiability on the Internet. After all, we can efficiently take the encrypted text and the key and produce the original text, so if P=NP we could efficiently find the key without knowing it beforehand. Password cracking would become trivial. On the other hand, there's whole classes of planning problems and resource allocation problems that we could solve effectively.
You may have heard the description NP-complete. An NP-complete problem is one that is NP (of course), and has this interesting property: if it is in P, every NP problem is, and so P=NP. If you could find a way to efficiently solve the Traveling Salesman problem, or logic puzzles from puzzle magazines, you could efficiently solve anything in NP. An NP-complete problem is, in a way, the hardest sort of NP problem.
So, if you can find an efficient general solution technique for any NP-complete problem, or prove that no such exists, fame and fortune are yours.
Use text break like this (\n):
<string name="sample_string"><![CDATA[some test line 1 \n some test line 2]]></string>
Updating this post (2015) : unbind/bind should not be used anymore with jQuery 1.7+. Use instead the function off(). Example :
$('#id').off('click');
$('#id').click(function(){
myNewFunction();
//Other code etc.
});
Be sure that you call a non-parameter function in .click, otherwise it will be ignored.
For mongo v3.6.3+ (or 2019 versions)
rm /var/lib/mongodb/mongod.lock
service mongodb restart
We had the same problem and you have to use
git fetch
git push origin branch_name
git branch -r
Hope this help someone facing the same problem
$('#container').clone().wrapAll("<div/>").parent().html();
Update: outerHTML works on firefox now so use the other answer unless you need to support very old versions of firefox
I got one more solution for this problem:
0 5 * * * . $HOME/.profile; /path/to/command/to/run
In this case it will pick all the environment variable defined in your $HOME/.profile
file.
Of course $HOME
is also not set, you have to replace it with the full path of your $HOME
.
Here's a simple little utility class that you can use to convert local date times from zone to zone, including a utility method directly to convert a local date time from the current zone to UTC (with main method so you can run it and see the results of a simple test):
import java.time.LocalDateTime;
import java.time.ZoneId;
import java.time.ZoneOffset;
import java.time.ZonedDateTime;
public final class DateTimeUtil {
private DateTimeUtil() {
super();
}
public static void main(final String... args) {
final LocalDateTime now = LocalDateTime.now();
final LocalDateTime utc = DateTimeUtil.toUtc(now);
System.out.println("Now: " + now);
System.out.println("UTC: " + utc);
}
public static LocalDateTime toZone(final LocalDateTime time, final ZoneId fromZone, final ZoneId toZone) {
final ZonedDateTime zonedtime = time.atZone(fromZone);
final ZonedDateTime converted = zonedtime.withZoneSameInstant(toZone);
return converted.toLocalDateTime();
}
public static LocalDateTime toZone(final LocalDateTime time, final ZoneId toZone) {
return DateTimeUtil.toZone(time, ZoneId.systemDefault(), toZone);
}
public static LocalDateTime toUtc(final LocalDateTime time, final ZoneId fromZone) {
return DateTimeUtil.toZone(time, fromZone, ZoneOffset.UTC);
}
public static LocalDateTime toUtc(final LocalDateTime time) {
return DateTimeUtil.toUtc(time, ZoneId.systemDefault());
}
}
I personally prefer the for (;;)
idiom (coming from a C/C++ point of view). While I agree that the while (true)
is more readable in a sense (and it's what I used way back when even in C/C++), I've turned to using the for
idiom because:
I think the fact that a loop doesn't terminate (in a normal fashion) is worth 'calling out', and I think that the for (;;)
does this a bit more.
Abstract classes and interfaces are semantically different, although their usage can overlap.
An abstract class is generally used as a building basis for similar classes. Implementation that is common for the classes can be in the abstract class.
An interface is generally used to specify an ability for classes, where the classes doesn't have to be very similar.
In Bootstrap 4
In my case I have just changed the .navbar
min-height
and the links font-size
and it decreased the navbar.
For example:
.navbar{
min-height:12px;
}
.navbar a {
font-size: 11.2px;
}
And this also worked for increasing the navbar height.
This also helps to change the navbar size when scrolling down the browser.
When I were trying install librosa
package with pip
(pip install librosa
), this error were appeared:
ERROR: Cannot uninstall 'llvmlite'. It is a distutils installed project and thus we cannot accurately determine which files belong to it which would lead to only a partial uninstall.
I tried to remove llvmlite
, but pip uninstall
could not remove it. So, I used capability of ignore
of pip
by this code:
pip install librosa --ignore-installed llvmlite
Indeed, you can use this rule for ignoring a package you don't want to consider:
pip install {package you want to install} --ignore-installed {installed package you don't want to consider}
You can convert it to a string, and then to an int:
print(int("".join(str(x) for x in [7,7,7,7])))
I know this is an old thread but for anyone looking to retrieve a script after ssms crashes do the following
You need URL Rewrite module, preferably v2 (I have no v1 installed, so cannot guarantee that it will work there, but it should).
Here is an example of such web.config -- it will force HTTPS for ALL resources (using 301 Permanent Redirect):
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<clear />
<rule name="Redirect to https" stopProcessing="true">
<match url=".*" />
<conditions>
<add input="{HTTPS}" pattern="off" ignoreCase="true" />
</conditions>
<action type="Redirect" url="https://{HTTP_HOST}{REQUEST_URI}" redirectType="Permanent" appendQueryString="false" />
</rule>
</rules>
</rewrite>
</system.webServer>
</configuration>
P.S. This particular solution has nothing to do with ASP.NET/PHP or any other technology as it's done using URL rewriting module only -- it is processed at one of the initial/lower levels -- before request gets to the point where your code gets executed.
Combining the ideas from:
Levon or Jesse, Faheel and ddrscott
with my formatting suggestion, you could write your query as:
query = ('SELECT'
' action.descr as "action"'
',role.id as role_id'
',role.descr as role'
' FROM'
' public.role_action_def'
',public.role'
',public.record_def'
',public.action'
' WHERE'
' role.id = role_action_def.role_id'
' AND'
' record_def.id = role_action_def.def_id'
' AND'
' action.id = role_action_def.action_id'
' AND'
' role_action_def.account_id = ?' # account_id
' AND'
' record_def.account_id = ?' # account_id
' AND'
' def_id = ?' # def_id
)
vars = (account_id, account_id, def_id) # A tuple of the query variables
cursor.execute(query, vars) # Using Python's sqlite3 module
Or like:
vars = []
query = ('SELECT'
' action.descr as "action"'
',role.id as role_id'
',role.descr as role'
' FROM'
' public.role_action_def'
',public.role'
',public.record_def'
',public.action'
' WHERE'
' role.id = role_action_def.role_id'
' AND'
' record_def.id = role_action_def.def_id'
' AND'
' action.id = role_action_def.action_id'
' AND'
' role_action_def.account_id = '
vars.append(account_id) or '?'
' AND'
' record_def.account_id = '
vars.append(account_id) or '?'
' AND'
' def_id = '
vars.append(def_id) or '?'
)
cursor.execute(query, tuple(vars)) # Using Python's sqlite3 module
Which could be interesting together with 'IN' and 'vars.extend(options) or n_options(len(options))', where:
def n_options(count):
return '(' + ','.join(count*'?') + ')'
Or with the hint from darkfeline, that you might still make mistakes with those leading spaces and separators and also with named placeholders:
SPACE_SEP = ' '
COMMA_SEP = ', '
AND_SEP = ' AND '
query = SPACE_SEP.join((
'SELECT',
COMMA_SEP.join((
'action.descr as "action"',
'role.id as role_id',
'role.descr as role',
)),
'FROM',
COMMA_SEP.join((
'public.role_action_def',
'public.role',
'public.record_def',
'public.action',
)),
'WHERE',
AND_SEP.join((
'role.id = role_action_def.role_id',
'record_def.id = role_action_def.def_id',
'action.id = role_action_def.action_id',
'role_action_def.account_id = :account_id',
'record_def.account_id = :account_id',
'def_id = :def_id',
)),
))
vars = {'account_id':account_id,'def_id':def_id} # A dictionary of the query variables
cursor.execute(query, vars) # Using Python's sqlite3 module
See documentation of Cursor.execute-function.

text-align: right
The text-align CSS property describes how inline content like text is aligned in its parent block element. text-align does not control the alignment of block elements itself, only their inline content.
See
<td class='alnright'>text to be aligned to right</td>

You cannot decrypt this password again but there is another method named "pwdcompare". Here is a example how to use it with SQL syntax:
USE TEMPDB
GO
declare @hash varbinary (255)
CREATE TABLE tempdb..h (id_num int, hash varbinary (255))
SET @hash = pwdencrypt('123') -- encryption
INSERT INTO tempdb..h (id_num,hash) VALUES (1,@hash)
SET @hash = pwdencrypt('123')
INSERT INTO tempdb..h (id_num,hash) VALUES (2,@hash)
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 2
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
INSERT INTO tempdb..h (id_num,hash)
VALUES (3,CONVERT(varbinary (255),
0x01002D60BA07FE612C8DE537DF3BFCFA49CD9968324481C1A8A8FE612C8DE537DF3BFCFA49CD9968324481C1A8A8))
SELECT TOP 1 @hash = hash FROM tempdb..h WHERE id_num = 3
SELECT pwdcompare ('123', @hash) AS [Success of check] -- Comparison
SELECT * FROM tempdb..h
DROP TABLE tempdb..h
GO
As the other poster mention, py2exe
, will generate an executable + some libraries to load. You can also have some data to add to your program.
Next step is to use an installer, to package all this into one easy-to-use installable/unistallable program.
I have used InnoSetup with delight for several years and for commercial programs, so I heartily recommend it.
Set minDate to current date in jQuery Datepicker :
$("input.DateFrom").datepicker({
minDate: new Date()
});
Scanner scan = new Scanner(System.in);
int i = scan.nextInt();
Double d = scan.nextDouble();
String newStr = "";
Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
while( charScanner.hasNext() ) {
String c = charScanner.next();
if (c.equalsIgnoreCase("\r")) {
break;
}
else {
newStr += c;
}
}
System.out.println("String: " + newStr);
System.out.println("Int: " + i);
System.out.println("Double: " + d);
This code works fine
With the dplyr
package, you can use summarise_all
, summarise_at
or summarise_if
functions to aggregate multiple variables simultaneously. For the example dataset you can do this as follows:
library(dplyr)
# summarising all non-grouping variables
df2 <- df1 %>% group_by(year, month) %>% summarise_all(sum)
# summarising a specific set of non-grouping variables
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(x1, x2), sum)
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(-date), sum)
# summarising a specific set of non-grouping variables using select_helpers
# see ?select_helpers for more options
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(starts_with('x')), sum)
df2 <- df1 %>% group_by(year, month) %>% summarise_at(vars(matches('.*[0-9]')), sum)
# summarising a specific set of non-grouping variables based on condition (class)
df2 <- df1 %>% group_by(year, month) %>% summarise_if(is.numeric, sum)
The result of the latter two options:
year month x1 x2
<dbl> <dbl> <dbl> <dbl>
1 2000 1 -73.58134 -92.78595
2 2000 2 -57.81334 -152.36983
3 2000 3 122.68758 153.55243
4 2000 4 450.24980 285.56374
5 2000 5 678.37867 384.42888
6 2000 6 792.68696 530.28694
7 2000 7 908.58795 452.31222
8 2000 8 710.69928 719.35225
9 2000 9 725.06079 914.93687
10 2000 10 770.60304 863.39337
# ... with 14 more rows
Note: summarise_each
is deprecated in favor of summarise_all
, summarise_at
and summarise_if
.
As mentioned in my comment above, you can also use the recast
function from the reshape2
-package:
library(reshape2)
recast(df1, year + month ~ variable, sum, id.var = c("date", "year", "month"))
which will give you the same result.
For me it was a very specific problem, I've got a Lg g5 to test my application on, and to reset my apps data I uninstalled it on the phone, but the phone has a "nice" feature to don't uninstall apps immediatly so you might can reinstall them within one day. So the app was installed but not usable(disabled) after removing the app from the phone completely it worked.
PCDATA - Parsed Character Data
XML parsers normally parse all the text in an XML document.
CDATA - (Unparsed) Character Data
The term CDATA is used about text data that should not be parsed by the XML parser.
Characters like "<" and "&" are illegal in XML elements.
That's an Object and you want to count the properties of it.
Object.keys(jsonArray).length

My approach:
define a default constraint on the ModDate
column with a value of GETDATE()
- this handles the INSERT
case
have a AFTER UPDATE
trigger to update the ModDate
column
Something like:
CREATE TRIGGER trg_UpdateTimeEntry
ON dbo.TimeEntry
AFTER UPDATE
AS
UPDATE dbo.TimeEntry
SET ModDate = GETDATE()
WHERE ID IN (SELECT DISTINCT ID FROM Inserted)
This is totally covered by the other answers, but I'll make it explicit. An object may have class attributes and static and dynamic instance attributes.
class foo:
classy = 1
@property
def dyno(self):
return 1
def __init__(self):
self.stasis = 2
def fx(self):
return 3
stasis
is static, dyno
is dynamic (cf. property decorator) and classy
is a class attribute. If we simply do __dict__
or vars
we will only get the static one.
o = foo()
print(o.__dict__) #{'stasis': 2}
print(vars(o)) #{'stasis': 2}
So if we want the others __dict__
will get everything (and more).
This includes magic methods and attributes and normal bound methods. So lets avoid those:
d = {k: getattr(o, k, '') for k in o.__dir__() if k[:2] != '__' and type(getattr(o, k, '')).__name__ != 'method'}
print(d) #{'stasis': 2, 'classy': 1, 'dyno': 1}
The type
called with a property decorated method (a dynamic attribute) will give you the type of the returned value, not method
. To prove this let's json stringify it:
import json
print(json.dumps(d)) #{"stasis": 2, "classy": 1, "dyno": 1}
Had it been a method it would have crashed.
TL;DR. try calling extravar = lambda o: {k: getattr(o, k, '') for k in o.__dir__() if k[:2] != '__' and type(getattr(o, k, '')).__name__ != 'method'}
for all three, but not methods nor magic.

There is a limit, but you can split your values into separate blocks of in()
Select *

select E.DeptId from [Employee] E
where E.Salary > 1000
group by E.DeptId

)
This question may seem old and odd, but when I was trying to load a module(lazy loading) and getting the same error, I realized I was missing an exports clause for the component that shipped as a part of a larger module.
This Angular.io Link explains why: Components/Services inside a module, remains private(or protected) by default. To make them public, you have to export them.
Expanding on @Robin Djikof's answer with @live-love code sample, this is what was technically missing in my case(Angular 8):
@NgModule({
declarations: [
SomeOtherComponent,
ProductListComponent
],
imports: [
DependantModule
],
exports: [ProductListComponent]
//<- This line makes ProductListComponent available outside the module,
//while keeping SomeOtherComponent private to the module
})
export class SomeLargeModule { }

I want change default directory dumpfile.
You could create a new directory and give it required privileges, for example:
SQL> CREATE DIRECTORY dmpdir AS '/opt/oracle';
Directory created.
SQL> GRANT read, write ON DIRECTORY dmpdir TO scott;
Grant succeeded.
To use the newly created directory, you could just add it as a parameter:
DIRECTORY=dmpdir
Oracle introduced a default directory from 10g R2, called DATA_PUMP_DIR, that can be used. To check the location, you could look into dba_directories:
SQL> select DIRECTORY_NAME, DIRECTORY_PATH from dba_directories where DIRECTORY_NAME = 'DATA_PUMP_DIR';
DIRECTORY_NAME DIRECTORY_PATH

means.
I ran into a similar problem and stumbled on this question. I got an SMTP Authentication Error but my user name / pass was correct. Here is what fixed it. I read this:
https://support.google.com/accounts/answer/6010255
In a nutshell, google is not allowing you to log in via smtplib because it has flagged this sort of login as "less secure", so what you have to do is go to this link while you're logged in to your google account, and allow the access:
https://www.google.com/settings/security/lesssecureapps
Once that is set (see my screenshot below), it should work.
Login now works:
smtpserver = smtplib.SMTP("smtp.gmail.com", 587)
smtpserver.ehlo()
smtpserver.starttls()
smtpserver.ehlo()
smtpserver.login('[email protected]', 'me_pass')
Response after change:
(235, '2.7.0 Accepted')
Response prior:
smtplib.SMTPAuthenticationError: (535, '5.7.8 Username and Password not accepted. Learn more at\n5.7.8 http://support.google.com/mail/bin/answer.py?answer=14257 g66sm2224117qgf.37 - gsmtp')
Still not working? If you still get the SMTPAuthenticationError but now the code is 534, its because the location is unknown. Follow this link:
https://accounts.google.com/DisplayUnlockCaptcha
Click continue and this should give you 10 minutes for registering your new app. So proceed to doing another login attempt now and it should work.
This doesn't seem to work right away you may be stuck for a while getting this error in smptlib
:
235 == 'Authentication successful'
503 == 'Error: already authenticated'
The message says to use the browser to sign in:
SMTPAuthenticationError: (534, '5.7.9 Please log in with your web browser and then try again. Learn more at\n5.7.9 https://support.google.com/mail/bin/answer.py?answer=78754 qo11sm4014232igb.17 - gsmtp')
After enabling 'lesssecureapps', go for a coffee, come back, and try the 'DisplayUnlockCaptcha' link again. From user experience, it may take up to an hour for the change to kick in. Then try the sign-in process again.
