use dirname(__FILE__)
in a global configuration file.
This feature is not available in older versions of Netbeans (up to 7.1) and the plugin is not supported anymore.
A plugin is now available for NetBeans 6.9.
I used to use PageSpiner from optima Software (http://www.optima-system.com/pagespinner/) but converted to Coda when Panic first released it and haven't looked back.
Now that the latest version has multi-file find and replace it has just about everything I need and I use it on a daily basis. Another vote for Coda from me.
This occurs when you try and write to a file that is currently being executed by the kernel, or execute a file that is currently open for writing.

Here is one good article to illustrate the difference among bind()
, apply()
and call()
, summarize it as below.
bind()
allows us to easily set which specific object will be bound to this when a function or method is invoked.
// This data variable is a global variable?
var data = [
{name:"Samantha", age:12},
{name:"Alexis", age:14}
]
var user = {
// local data variable?
data :[
{name:"T. Woods", age:37},
{name:"P. Mickelson", age:43}
],
showData:function (event) {
var randomNum = ((Math.random () * 2 | 0) + 1) - 1; // random number between 0 and 1?
console.log (this.data[randomNum].name + " " + this.data[randomNum].age);
}
}
// Assign the showData method of the user object to a variable?
var showDataVar = user.showData;
showDataVar (); // Samantha 12 (from the global data array, not from the local data array)?
/*
This happens because showDataVar () is executed as a global function and use of this inside
showDataVar () is bound to the global scope, which is the window object in browsers.
*/
// Bind the showData method to the user object?
var showDataVar = user.showData.bind (user);
// Now the we get the value from the user object because the this keyword is bound to the user object?
showDataVar (); // P. Mickelson 43?
bind()
allow us to borrow methods
// Here we have a cars object that does not have a method to print its data to the console?
var cars = {
data:[
{name:"Honda Accord", age:14},
{name:"Tesla Model S", age:2}
]
}
// We can borrow the showData () method from the user object we defined in the last example.?
// Here we bind the user.showData method to the cars object we just created.?
cars.showData = user.showData.bind (cars);
cars.showData (); // Honda Accord 14?
One problem with this example is that we are adding a new method showData
on the cars
object and
we might not want to do that just to borrow a method because the cars object might already have a property or method name showData
.
We don’t want to overwrite it accidentally. As we will see in our discussion of Apply
and Call
below,
it is best to borrow a method using either the Apply
or Call
method.
bind()
allow us to curry a function
Function Currying, also known as partial function application, is the use of a function (that accept one or more arguments) that returns a new function with some of the arguments already set.
function greet (gender, age, name) {
// if a male, use Mr., else use Ms.?
var salutation = gender === "male" ? "Mr. " : "Ms. ";
if (age > 25) {
return "Hello, " + salutation + name + ".";
}else {
return "Hey, " + name + ".";
}
}
We can use bind()
to curry this greet
function
// So we are passing null because we are not using the "this" keyword in our greet function.
var greetAnAdultMale = greet.bind (null, "male", 45);
greetAnAdultMale ("John Hartlove"); // "Hello, Mr. John Hartlove."
var greetAYoungster = greet.bind (null, "", 16);
greetAYoungster ("Alex"); // "Hey, Alex."?
greetAYoungster ("Emma Waterloo"); // "Hey, Emma Waterloo."
apply()
or call()
to set this value
The apply
, call
, and bind
methods are all used to set the this value when invoking a method, and they do it in slightly
different ways to allow use direct control and versatility in our JavaScript code.
The apply
and call
methods are almost identical when setting the this value except that you pass the function parameters to apply ()
as an array, while you have to list the parameters individually to pass them to the call ()
method.
Here is one example to use call
or apply
to set this in the callback function.
// Define an object with some properties and a method?
// We will later pass the method as a callback function to another function?
var clientData = {
id: 094545,
fullName: "Not Set",
// setUserName is a method on the clientData object?
setUserName: function (firstName, lastName) {
// this refers to the fullName property in this object?
this.fullName = firstName + " " + lastName;
}
};
function getUserInput (firstName, lastName, callback, callbackObj) {
// The use of the Apply method below will set the "this" value to callbackObj?
callback.apply (callbackObj, [firstName, lastName]);
}
// The clientData object will be used by the Apply method to set the "this" value?
getUserInput ("Barack", "Obama", clientData.setUserName, clientData);
// the fullName property on the clientData was correctly set?
console.log (clientData.fullName); // Barack Obama
Borrow functions with apply
or call
Borrow Array methods
Let’s create an array-like
object and borrow some array methods to operate on the our array-like object.
// An array-like object: note the non-negative integers used as keys?
var anArrayLikeObj = {0:"Martin", 1:78, 2:67, 3:["Letta", "Marieta", "Pauline"], length:4 };
// Make a quick copy and save the results in a real array:
// First parameter sets the "this" value?
var newArray = Array.prototype.slice.call (anArrayLikeObj, 0);
console.log (newArray); // ["Martin", 78, 67, Array[3]]?
// Search for "Martin" in the array-like object?
console.log (Array.prototype.indexOf.call (anArrayLikeObj, "Martin") === -1 ? false : true); // true?
Another common case is that convert arguments
to array as following
// We do not define the function with any parameters, yet we can get all the arguments passed to it?
function doSomething () {
var args = Array.prototype.slice.call (arguments);
console.log (args);
}
doSomething ("Water", "Salt", "Glue"); // ["Water", "Salt", "Glue"]
Borrow other methods
var gameController = {
scores :[20, 34, 55, 46, 77],
avgScore:null,
players :[
{name:"Tommy", playerID:987, age:23},
{name:"Pau", playerID:87, age:33}
]
}
var appController = {
scores :[900, 845, 809, 950],
avgScore:null,
avg :function () {
var sumOfScores = this.scores.reduce (function (prev, cur, index, array) {
return prev + cur;
});
this.avgScore = sumOfScores / this.scores.length;
}
}
// Note that we are using the apply () method, so the 2nd argument has to be an array?
appController.avg.apply (gameController);
console.log (gameController.avgScore); // 46.4?
// appController.avgScore is still null; it was not updated, only gameController.avgScore was updated?
console.log (appController.avgScore); // null?
Use apply()
to execute variable-arity function
The Math.max
is one example of variable-arity function,
// We can pass any number of arguments to the Math.max () method?
console.log (Math.max (23, 11, 34, 56)); // 56
But what if we have an array of numbers to pass to Math.max
? We cannot do this:
var allNumbers = [23, 11, 34, 56];
// We cannot pass an array of numbers to the the Math.max method like this?
console.log (Math.max (allNumbers)); // NaN
This is where the apply ()
method helps us execute variadic functions. Instead of the above, we have to pass the array of numbers using apply (
) thus:
var allNumbers = [23, 11, 34, 56];
// Using the apply () method, we can pass the array of numbers:
console.log (Math.max.apply (null, allNumbers)); // 56
One can reproduce the error with the code below:
public ActionResult ClosingTheConnectionAction(){
try
{
//we need to set buffer to false to
//make sure data is written in chunks
Response.Buffer = false;
var someText = "Some text here to make things happen ;-)";
var content = GetBytes( someText );
for(var i=0; i < 100; i++)
{
Response.OutputStream.Write(content, 0, content.Length);
}
return View();
}
catch(HttpException hex)
{
if (hex.Message.StartsWith("The remote host closed the connection. The error code is 0x800704CD."))
{
//react on remote host closed the connection exception.
var msg = hex.Message;
}
}
catch(Exception somethingElseHappened)
{
//handle it with some other code
}
return View();
}
Now run the website in debug mode. Put a breakpoint in the loop that writes to the output stream. Go to that action method and after the first iteration passed close the tab of the browser. Hit F10 to continue the loop. After it hit the next iteration you will see the exception. Enjoy your exception :-)
Instance variable on a class:
class Parent
@things = []
def self.things
@things
end
def things
self.class.things
end
end
class Child < Parent
@things = []
end
Parent.things << :car
Child.things << :doll
mom = Parent.new
dad = Parent.new
p Parent.things #=> [:car]
p Child.things #=> [:doll]
p mom.things #=> [:car]
p dad.things #=> [:car]
Class variable:
class Parent
@@things = []
def self.things
@@things
end
def things
@@things
end
end
class Child < Parent
end
Parent.things << :car
Child.things << :doll
p Parent.things #=> [:car,:doll]
p Child.things #=> [:car,:doll]
mom = Parent.new
dad = Parent.new
son1 = Child.new
son2 = Child.new
daughter = Child.new
[ mom, dad, son1, son2, daughter ].each{ |person| p person.things }
#=> [:car, :doll]
#=> [:car, :doll]
#=> [:car, :doll]
#=> [:car, :doll]
#=> [:car, :doll]
With an instance variable on a class (not on an instance of that class) you can store something common to that class without having sub-classes automatically also get them (and vice-versa). With class variables, you have the convenience of not having to write self.class
from an instance object, and (when desirable) you also get automatic sharing throughout the class hierarchy.
Merging these together into a single example that also covers instance variables on instances:
class Parent
@@family_things = [] # Shared between class and subclasses
@shared_things = [] # Specific to this class
def self.family_things
@@family_things
end
def self.shared_things
@shared_things
end
attr_accessor :my_things
def initialize
@my_things = [] # Just for me
end
def family_things
self.class.family_things
end
def shared_things
self.class.shared_things
end
end
class Child < Parent
@shared_things = []
end
And then in action:
mama = Parent.new
papa = Parent.new
joey = Child.new
suzy = Child.new
Parent.family_things << :house
papa.family_things << :vacuum
mama.shared_things << :car
papa.shared_things << :blender
papa.my_things << :quadcopter
joey.my_things << :bike
suzy.my_things << :doll
joey.shared_things << :puzzle
suzy.shared_things << :blocks
p Parent.family_things #=> [:house, :vacuum]
p Child.family_things #=> [:house, :vacuum]
p papa.family_things #=> [:house, :vacuum]
p mama.family_things #=> [:house, :vacuum]
p joey.family_things #=> [:house, :vacuum]
p suzy.family_things #=> [:house, :vacuum]
p Parent.shared_things #=> [:car, :blender]
p papa.shared_things #=> [:car, :blender]
p mama.shared_things #=> [:car, :blender]
p Child.shared_things #=> [:puzzle, :blocks]
p joey.shared_things #=> [:puzzle, :blocks]
p suzy.shared_things #=> [:puzzle, :blocks]
p papa.my_things #=> [:quadcopter]
p mama.my_things #=> []
p joey.my_things #=> [:bike]
p suzy.my_things #=> [:doll]
Lots of other answers here, but to answer precisely the question you asked (before @MarkAmery went and edited the original question and changed the meaning):
>>> f = open('myfile.txt')
>>> data = f.read()
>>> # I'm assuming you had the above before asking the question
>>> first_line = data.split('\n', 1)[0]
In other words, if you've already read in the file (as you said), and have a big block of data in memory, then to get the first line from it efficiently, do a split() on the newline character, once only, and take the first element from the resulting list.
Note that this does not include the \n
character at the end of the line, but I'm assuming you don't want it anyway (and a single-line file may not even have one). Also note that although it's pretty short and quick, it does make a copy of the data, so for a really large blob of memory you may not consider it "efficient". As always, it depends...
Try something like the following example, quoted from the output of IF /?
on Windows XP:
IF EXIST filename. ( del filename. ) ELSE ( echo filename. missing. )
You can also check for a missing file with IF NOT EXIST
.
The IF
command is quite powerful. The output of IF /?
will reward careful reading. For that matter, try the /?
option on many of the other built-in commands for lots of hidden gems.
In relative layout you need specify textview height:
android:layout_height="100dp"
Or specify lines attribute:
android:lines="3"
Windows & GitBash Terminal I needed to use this command inside Windows / Webstorm / GitBash terminal

It seems like this is a pretty vague error, so I will share what I did to fix it when I ran into this:
Using Xcode 10.1 and Swift 4.2 I tried pretty much all the suggestions here but none of them worked for me, then I realized a dependency I was using was not compatible with Swift 4.2 and that was causing me to get this error on other pods. So to fix it I just had to force that pod to use Swift 4.0 by putting this at the end of my Podfile
:
post_install do |installer|
installer.pods_project.targets.each do |target|
if ['TKRadarChart'].include? target.name
target.build_configurations.each do |config|
config.build_settings['SWIFT_VERSION'] = '4.0'
end
end
end
end
numberList=[16,19,42,43,74,66]
largest = numberList[0]
for num2 in numberList:
if num2 > largest:
largest=num2
print(largest)
gives largest number out of the numberslist without using a Max statement
Well, what is ID
here? In particular, is it a local variable? There are some scope / capture issues, which mean that it may be desirable to use a second variable copy, just for the query:
var id = ID;
BlogPost post = (from p in dc.BlogPosts
where p.BlogPostID == id
select p).Single();
Also; if this is LINQ-to-SQL, then in the current version you get a slightly better behaviour if you use the form:
var id = ID;
BlogPost post = dc.BlogPosts.Single(p => p.BlogPostID == id);
In [1]: df
Out[1]:
data
0 1
1 2
2 3
3 4
You want to apply a function that conditionally returns a value based on the selected dataframe column.
In [2]: df['data'].apply(lambda x: 'true' if x <= 2.5 else 'false')
Out[2]:
0 true
1 true
2 false
3 false
Name: data
You can then assign that returned column to a new column in your dataframe:
In [3]: df['desired_output'] = df['data'].apply(lambda x: 'true' if x <= 2.5 else 'false')
In [4]: df
Out[4]:
data desired_output
0 1 true
1 2 true
2 3 false
3 4 false
It's caused by n % x
where x = 0
in the first loop iteration. You can't calculate a modulus with respect to 0.
If you need to find the max/min of a hash, you can use #max_by
or #min_by
people = {'joe' => 21, 'bill' => 35, 'sally' => 24}
people.min_by { |name, age| age } #=> ["joe", 21]
people.max_by { |name, age| age } #=> ["bill", 35]

You have it backwards. ob_start does not buffer the headers, it buffers the content. Using ob_start
allows you to keep the content in a server-side buffer until you are ready to display it.
This is commonly used to so that pages can send headers 'after' they've 'sent' some content already (ie, deciding to redirect half way through rendering a page).

Dictionaries in Python are data structures that store key-value pairs. You can use them like associative arrays. Curly braces are used when declaring dictionaries:
d = {'One': 1, 'Two' : 2, 'Three' : 3 }
print d['Two'] # prints "2"
Curly braces are not used to denote control levels in Python. Instead, Python uses indentation for this purpose.
I think you really need some good resources for learning Python in general. See https://stackoverflow.com/q/175001/10077
A null key can also be helpful when the map stores data for UI selections where the map key represents a bean field.
A corresponding null field value would for example be represented as "(please select)" in the UI selection.
Assume if all the input elements are inside a form u can refer the below code.
// get all the inputs into an array.
var $inputs = $('#myForm :input');
// not sure if you wanted this, but I thought I'd add it.
// get an associative array of just the values.
var values = {};
$inputs.each(function() {
values[this.name] = $(this).val();
});
Apart from all given answers I find this piece of code very straightforward. AS DateTime.MinValue is 1/1/1, we have to subtract 1 from month, years and days.
var timespan = endDate.Subtract(startDate);
var tempdate = DateTime.MinValue + timespan;
var totalMonths = (tempdate.Year - 1) * 12 + tempdate.Month - 1;
var totalDays = tempdate.Day - 1;
if (totalDays > 0)
{
totalMonths = totalMonths + 1;
}
Simple solution which will work on,
Input scroll events
Copy paste via keyboard
Copy paste via mouse
Input type etc cases
<input id="maxLengthCheck"
name="maxLengthCheck"
type="number"
step="1"
min="0"
oninput="this.value = this.value > 5 ? 5 : Math.abs(this.value)" />
See there is condition on this.value > 5, just update 5 with your max limit.
Explanation:
If our input number is more then our limit update input value this.value with proper number Math.abs(this.value)
Else just make it to your max limit which is again 5.
width: 80vmin; height: 80vmin;
CSS does 80% of the smallest view, height or width

Provisioning a SQL Server Virtual Machine on Windows Azure. These initial instructions provided 25% of the answer.
How to Troubleshoot Connecting to the SQL Server Database Engine. Reading this carefully provided another 50% of the answer.
How to configure SQL server to listen on different ports on different IP addresses?. This enabled setting up static ports for named instances (eg SQLEXPRESS.) It took us the final 25% of the way to the answer.

Deleting the .git
folder may cause problems in your git repository. If you want to delete all your commit history but keep the code in its current state, it is very safe to do it as in the following:
Checkout
git checkout --orphan latest_branch
Add all the files
git add -A
Commit the changes
git commit -am "commit message"
Delete the branch
git branch -D main
Rename the current branch to main
git branch -m main
Finally, force update your repository
git push -f origin main
PS: this will not keep your old commit history around
I got this issue when i wrote :
export default connect (mapDispatchToProps,mapStateToProps)(SearchInsectsComponent);
instead of
export default connect (mapStateToProps,mapDispatchToProps)(SearchInsectsComponent);
The error you are getting is in line 3. i.e. it is not in
CONSTRAINT no_duplicate_tag UNIQUE (question_id, tag_id)
but earlier:
CREATE TABLE tags
(
(question_id, tag_id) NOT NULL,
Correct table definition is like pilcrow showed.
And if you want to add unique on tag1, tag2, tag3 (which sounds very suspicious), then the syntax is:
CREATE TABLE tags (
question_id INTEGER NOT NULL,
tag_id SERIAL NOT NULL,
tag1 VARCHAR(20),
tag2 VARCHAR(20),
tag3 VARCHAR(20),
PRIMARY KEY(question_id, tag_id),
UNIQUE (tag1, tag2, tag3)
);
or, if you want to have the constraint named according to your wish:
CREATE TABLE tags (
question_id INTEGER NOT NULL,
tag_id SERIAL NOT NULL,
tag1 VARCHAR(20),
tag2 VARCHAR(20),
tag3 VARCHAR(20),
PRIMARY KEY(question_id, tag_id),

NoGray is nice eye candy but there are a few usability considerations. Firstly, analog clocks are growing increasingly obscure, and younger people sometimes have a difficult time reading them. Secondly, dragging with a mouse to a specific time is a bit tedious, just like the time pickers that use a slider. Thirdly, keyboard interaction for this picker is a bit sporadic.
For a more usable time picker, check out the Any+Time™ Datepicker/Timepicker AJAX Calendar Widget. It's perhaps the fastest-and-easiest-to-use time picker available, because it uses simple buttons to select specific times with speed and ease.
An interesting test of usability is this: pick an odd time (say, 10:32pm), then see how long it takes to accurately select that time using various time pickers. You can probably do it faster with Any+Time™ than you could write out the time by hand--just try to find another picker you can say that about! Not to mention, Any+Time™ supports a countless variety of date/time formats, 12/24-hour clock, full CSS (or jQuery UI) customization and even time zones!
Here is some relevant code:
// Create a trust manager that does not validate certificate chains
TrustManager[] trustAllCerts = new TrustManager[]{
new X509TrustManager() {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
return null;
}
public void checkClientTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
public void checkServerTrusted(
java.security.cert.X509Certificate[] certs, String authType) {
}
}
};
// Install the all-trusting trust manager
try {
SSLContext sc = SSLContext.getInstance("SSL");
sc.init(null, trustAllCerts, new java.security.SecureRandom());
HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
} catch (Exception e) {
}
// Now you can access an https URL without having the certificate in the truststore
try {
URL url = new URL("https://hostname/index.html");
} catch (MalformedURLException e) {
}
This will completely disable SSL checking—just don't learn exception handling from such code!
To do what you want, you would have to implement a check in your TrustManager that prompts the user.
The way I implemented automatical reformating like in Microsoft Visual Studio (It doesn't work perfect):
1. Edit > Macros > Start Macro Recording
2. Press continuously: Enter + Ctrl+Alt+I
3. Edit > Macros > Stop Macro Recording (Name it for example ReformatingByEnter)
Now we need to perform same actions but for Ctrl+Alt+L+;
4. Edit > Macros > Start Macro Recording
5. Press continuously: ; + Ctrl+Alt+I
6. Edit > Macros > Stop Macro Recording (Name it for example ReformatingBy;)
Now we need to assign HotKeys to these macros:
7. File > Settings > Keymap > press on a gear button > Duplicate...
8. Unfold a macro button (beneath) and by right clicking on two
ours macros assign HotKeys for them: "Enter" and ";" correspondingly.

Check out the request module.

You can fix the issue with the following steps:
sudo cd /var/lib/php/session
. If it does not exist then sudo mkdir /var/lib/php/session
or double check the logs to make sure you have the correct path.sudo chmod 666 /var/lib/php/session
.Rerun you script and it should be working fine, however, it's not recommended to leave the folder with full permissions. For security, files and folders should only have the minimum permissions required. The following steps will fix that:
sudo ls -l
to find out the owner of the session file.sudo chown user /var/lib/php/session
.sudo chmod 600 /var/lib/php/session
.NB
You might not need to use the sudo
command.
However using this 'self.pageViewController setViewControllers' method call does not call 'viewDidDissapear' on the viewController for the page that has been turned away, whereas manually turning a page does call viewDidDissapear on the turned away page. I believe this is the cause of my crash

ll `ls`
or
ls -l $(ls)
u can use this:
protected void btnConfirm_Click(object sender, EventArgs e)
{
Response.Redirect("Confirm.aspx");
}
You have basically two options:
export TESTVARIABLE
) before executing the 2nd script.. test2.sh
and it will run in the same shell. This would let you share more complex variables like arrays easily, but also means that the other script could modify variables in the source shell.UPDATE:
To use export
to set an environment variable, you can either use an existing variable:
A=10
# ...
export A
This ought to work in both bash
and sh
. bash
also allows it to be combined like so:
export A=10
This also works in my sh
(which happens to be bash
, you can use echo $SHELL
to check). But I don't believe that that's guaranteed to work in all sh
, so best to play it safe and separate them.
Any variable you export in this way will be visible in scripts you execute, for example:
a.sh:
#!/bin/sh
MESSAGE="hello"
export MESSAGE
./b.sh
b.sh:
#!/bin/sh
echo "The message is: $MESSAGE"
Then:
$ ./a.sh
The message is: hello
The fact that these are both shell scripts is also just incidental. Environment variables can be passed to any process you execute, for example if we used python instead it might look like:
a.sh:
#!/bin/sh
MESSAGE="hello"
export MESSAGE
./b.py
b.py:
#!/usr/bin/python
import os
print 'The message is:', os.environ['MESSAGE']
Sourcing:
Instead we could source like this:
a.sh:
#!/bin/sh
MESSAGE="hello"
. ./b.sh
b.sh:
#!/bin/sh
echo "The message is: $MESSAGE"
Then:
$ ./a.sh
The message is: hello
This more or less "imports" the contents of b.sh
directly and executes it in the same shell. Notice that we didn't have to export the variable to access it. This implicitly shares all the variables you have, as well as allows the other script to add/delete/modify variables in the shell. Of course, in this model both your scripts should be the same language (sh
or bash
). To give an example how we could pass messages back and forth:
a.sh:
#!/bin/sh
MESSAGE="hello"
. ./b.sh
echo "[A] The message is: $MESSAGE"
b.sh:
#!/bin/sh
echo "[B] The message is: $MESSAGE"
MESSAGE="goodbye"
Then:
$ ./a.sh
[B] The message is: hello
[A] The message is: goodbye
This works equally well in bash
. It also makes it easy to share more complex data which you could not express as an environment variable (at least without some heavy lifting on your part), like arrays or associative arrays.
it would be something like this
sqlplus -s /nolog <<-!
connect ${ORACLE_UID}/${ORACLE_PWD}@${ORACLE_DB};
whenever sqlerror exit sql.sqlcode;
set pagesize 0;
set linesize 150;
spool <query_output.dat> APPEND
@$<input_query.dat>
spool off;
exit;
!

ORACLE_PWD=<password>

By default mysqldump
always creates the CREATE DATABASE IF NOT EXISTS db_name;
statement at the beginning of the dump file.
[EDIT] Few things about the mysqldump
file and it's options:
--all-databases
, -A
Dump all tables in all databases. This is the same as using the --databases
option and naming all the databases on the command line.
--add-drop-database
Add a DROP DATABASE
statement before each CREATE DATABASE
statement. This option is typically used in conjunction with the --all-databases
or --databases
option because no CREATE DATABASE
statements are written unless one of those options is specified.
--databases
, -B
Dump several databases. Normally, mysqldump
treats the first name argument on the command line as a database name and following names as table names. With this option, it treats all name arguments as database names. CREATE DATABASE
and USE
statements are included in the output before each new database.
--no-create-db
, -n
This option suppresses the CREATE DATABASE
statements that are otherwise included in the output if the --databases
or --all-databases
option is given.
Some time ago, there was similar question actually asking about not having such statement on the beginning of the file (for XML file). Link to that question is here.
So to answer your question:
--add-drop-database
option in your mysqldump
statement.--databases
or --all-databases
and the CREATE DATABASE
syntax will be added

Step 1: Create a Type as Table with name TableType that will accept a table having one varchar column
create type TableType
as table ([value] varchar(100) null)
Step 2: Create a function that will accept above declared TableType as Table-Valued Parameter and String Value as Separator
create function dbo.fn_get_string_with_delimeter (@table TableType readonly,@Separator varchar(5))
returns varchar(500)
As
begin
declare @return varchar(500)
set @return = stuff((select @Separator + value from @table for xml path('')),1,1,'')
return @return
end
Step 3: Pass table with one varchar column to the user-defined type TableType and ',' as separator in the function
select dbo.fn_get_string_with_delimeter(@tab, ',')

int x = 0xFF; //your number - 11111111
How do I for example read a 3 bit integer value starting at the second bit

// and you shift it 2 to the left
This way will let you run the test scripts from wherever you want without messing around with system variables from the command line.
This adds the main project folder to the python path, with the location found relative to the script itself, not relative to the current working directory.
import sys, os
sys.path.insert(0, os.path.dirname(os.path.dirname(os.path.realpath(__file__))))
Add that to the top of all your test scripts. That will add the main project folder to the system path, so any module imports that work from there will now work. And it doesn't matter where you run the tests from.
You can obviously change the project_path_hack file to match your main project folder location.
Deleting the ~/.m2/repository
will solve your problem. But, if you still need to keep the old ~/.m2/repository
you can just change the maven local path temporarily.
If you are working on IntelliJ just go to Maven Settings and change the Local Repository path to somewhere else. You may need to tick the override checkbox near there.
I have to agree with foobarbecue (I don't have enough recs to be able to simply insert a comment under his post):
It's now recommended that python notebook isn't started wit the argument --pylab
, and according to Fernando Perez (creator of ipythonnb) %matplotlib inline
should be the initial notebook command.
If all of your tables are in a single schema, this approach could work (below code assumes that the name of your schema is public
)
DROP SCHEMA public CASCADE;
CREATE SCHEMA public;
If you are using PostgreSQL 9.3 or greater, you may also need to restore the default grants.
GRANT ALL ON SCHEMA public TO postgres;
GRANT ALL ON SCHEMA public TO public;
I would like to show a little example on how is
and ==
are involved in immutable types. Try that:
a = 19998989890
b = 19998989889 +1
>>> a is b
False
>>> a == b
True
is
compares two objects in memory, ==
compares their values. For example, you can see that small integers are cached by Python:
c = 1
b = 1
>>> b is c
True
You should use ==
when comparing values and is
when comparing identities. (Also, from an English point of view, "equals" is different from "is".)
In Spring 5, or maybe in earlier versions, there is MediaType
class. It has already correct line, if you want to follow DRY:
public static final String APPLICATION_JSON_UTF8_VALUE = "application/json;charset=UTF-8";
So I use this set of controller-related annotations:
@RestController
@RequestMapping(value = "my/api/url", produces = APPLICATION_JSON_UTF8_VALUE)
public class MyController {
// ... Methods here
}
It is marked deprecated in the docs, but I've run into this issue and it is better than copy-pastying the aforementioned line on every method/controller throughout your application, I think.
I had the same issue, but I found a good solution here: Stop caching for PHP 5.5.3 in MAMP
Basically find the php.ini file and comment out the OPCache lines. I hope this alternative answer helps others else out as well.
You should rather use GROUP BY UNIX_TIMESTAMP(time_stamp) DIV 300
instead of round(../300) because of the rounding I found that some records are counted into two grouped result sets.
You simply misspelled $stateParam

Try to configure the setting of your projects, it is usually due to x86/x64 architecture problems:
Go and set your choice as shown:
The isinstance
built-in is the preferred way if you really must, but even better is to remember Python's motto: "it's easier to ask forgiveness than permission"!-) (It was actually Grace Murray Hopper's favorite motto;-). I.e.:
def my_print(text, begin, end):
"Print 'text' in UPPER between 'begin' and 'end' in lower"
try:
print begin.lower() + text.upper() + end.lower()
except (AttributeError, TypeError):
raise AssertionError('Input variables should be strings')
This, BTW, lets the function work just fine on Unicode strings -- without any extra effort!-)
Don't forget to place your css links in the <head>

Note that you can also use the C99 fixed-width types perfectly well in Objective-C:
#import <stdint.h>
...
int32_t x; // guaranteed to be 32 bits on any platform
The wikipedia page has a decent description of what's available in this header if you don't have a copy of the C standard (you should, though, since Objective-C is just a tiny extension of C). You may also find the headers limits.h
and inttypes.h
to be useful.
There must be something wrong with the way you access the array's items. Here's how it's done:
for elem in "${files[@]}"
...
From the bash manpage:
Any element of an array may be referenced using ${name[subscript]}. ... If subscript is @ or *, the word expands to all members of name. These subscripts differ only when the word appears within double quotes. If the word is double-quoted, ${name[*]} expands to a single word with the value of each array member separated by the first character of the IFS special variable, and ${name[@]} expands each element of name to a separate word.
Of course, you should also use double quotes when accessing a single member
cp "${files[0]}" /tmp
For those not interested in USB debugging or using adb
there is an easier solution. In Android 6 (Not sure about prior version) there is an option under developer tools: Take Bug Report
Clicking this option will prepare a bug report and prompt you to save it to drive or have it sent in email.
I found this to be the easiest way to get logs. I don't like to turn on USB debugging.
Late to the party, but another easy way of comparing NSDate objects is to convert them into primitive types which allows for easy use of '>' '<' '==' etc
eg.
if ([dateA timeIntervalSinceReferenceDate] > [dateB timeIntervalSinceReferenceDate]) {
//do stuff
}
timeIntervalSinceReferenceDate
converts the date into seconds since the reference date (1 January 2001, GMT). As timeIntervalSinceReferenceDate
returns a NSTimeInterval (which is a double typedef), we can use primitive comparators.
If you created the DLL using .net 4.5 , then copy and paste this command on command prompt.
%SystemRoot%\Microsoft.NET\Framework\v4.0.30319\regasm.exe MyAssembly.dll
You are running the [
(aka test
) command with the argument "false", not running the command false
. Since "false" is a non-empty string, the test
command always succeeds. To actually run the command, drop the [
command.
if false; then
echo "True"
else
echo "False"

The MaxAge of -1 signals that you want the cookie to persist for the duration of the session. You want to set MaxAge to 0 instead.
From the API documentation:
A negative value means that the cookie is not stored persistently and will be deleted when the Web browser exits. A zero value causes the cookie to be deleted.
An ftl file could just have a series of html tags just as a JSP page or it can have freemarker template coding for representing the objects passed on from a controller java file.
But, its actual ability is to combine the contents of a java class and view/client side stuff(html/ JQuery/ javascript etc). It is quite similar to velocity. You could map a method or object of a class to a freemarker (.ftl) page and use it as if it is a variable or a functionality created in the very page.
Another interesting solution might be to do this:
<a href="#" itemid="<%itemid%>" itemname="<%itemname%>" onclick="SelectSurveyItem(this.itemid, this.itemname); return false;">Select</a>
Then you can use a standard HTML-encoding on both the variables, without having to worry about the extra complication of the javascript quoting.
Yes, this does create HTML that is strictly invalid. However, it is a valid technique, and all modern browsers support it.
If it was my, I'd probably go with my first suggestion, and ensure the values are HTML-encoded and have single-quotes escaped.
You can use aspnet_compiler for this:
C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_compiler -v /Virtual/Application/Path/Or/Path/In/IIS/Metabase -p C:\Path\To\Your\WebProject -f -errorstack C:\Where\To\Put\Compiled\Site
where "/Virtual/Application/Path/Or/Path/In/IIS/Metabase" is something like this: "/MyApp" or "/lm/w3svc2/1/root/"
Also there is a AspNetCompiler Task on MSDN, showing how to integrate aspnet_compiler with MSBuild:

The first thing you should do is learn to read error messages. What does it tell you -- that you can't use two strings with the divide operator.
So, ask yourself why they are strings and how do you make them not-strings. They are strings because all input is done via strings. And the way to make then not-strings is to convert them.
One way to convert a string to an integer is to use the int function. For example:
percent = (int(pyc) / int(tpy)) * 100
The MyKey class must implement Serializable
if you are using @IdClass
There is the easiest method, using File::Slurp
module:
use File::Slurp;
my @lines = read_file("filename", chomp => 1); # will chomp() each line
If you need some validation for each line you can use grep
in front of read_file
.
For example, filter lines which contain only integers:
my @lines = grep { /^\d+$/ } read_file("filename", chomp => 1);
Use git archive branch-index | tar -x -C your-folder-on-PC
to clone a branch to another folder. I think, then you can copy any file that you need
Try the following.
$d = [datetime](Get-ItemProperty -Path $source -Name LastWriteTime).lastwritetime
This is part of the item property weirdness. When you run Get-ItemProperty it does not return the value but instead the property. You have to use one more level of indirection to get to the value.
you can use DateTime.ParseExact
with the format string
DateTime dt = DateTime.ParseExact(inputString, formatString, System.Globalization.CultureInfo.InvariantCulture);
Above will throw an exception if the given string not in given format.
use DateTime.TryParseExact
if you don't need exception in case of format incorrect but you can check the return value of that method to identify whether parsing value success or not.
Another simple approach is to let Lombok
generate the toString
method for you.
For this:
Lombok
to your project@ToString
to the definition of your classSo for example in your case, your class would look like this:
@ToString
public class Contact {
private String name;
private String location;
private String address;
private String email;
private String phone;
private String fax;
// Getters and setters.
}
Example of output in this case:
Contact(name=John, location=USA, address=SF, [email protected], phone=99999, fax=88888)
More details about how to use the annotation @ToString
.
NB: You can also let Lombok
generate the getters and setters for you, here is the full feature list.
You can do it like this:
$str = "abc-123-xyz-789";
$last = array_pop( explode('-', $str) );
echo $last; //echoes 789
Tested with: log4j-ap 2.13.2, log4j-core 2.13.2.
<build> <resources> <resource> <filtering>false</filtering> <directory>src/main/resources</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </build>
You can simply add this when you are using same controller to redirect
var url = "YourActionName?parameterName=" + parameterValue;
window.location.href = url;
Follow these steps to run your application on the device connected.
1. Change directories to the root of your Android project and execute:

CORRECTION: I should take my own advice and actually read the documentation. It says that this does not apply to LD_LIBRARY_PATH: Since Ubuntu 9.04 Jaunty Jackalope, LD_LIBRARY_PATH cannot be set in $HOME/.profile, /etc/profile, nor /etc/environment files. You must use /etc/ld.so.conf.d/.conf configuration files.* So user1824407's answer is spot on.
FMJ can do this, as can the supporting library it uses, LTI-CIVIL. Both are on sourceforge.
UPDATED
I've updated your demo: http://jsfiddle.net/terryyounghk/QS56z/18/
Also, I've changed two ^=
to *=
. See http://api.jquery.com/category/selectors/
And note the :checked
selector. See http://api.jquery.com/checked-selector/
function createcodes() {
//run through each row
$('.authors-list tr').each(function (i, row) {
// reference all the stuff you need first
var $row = $(row),
$family = $row.find('input[name*="family"]'),
$grade = $row.find('input[name*="grade"]'),
$checkedBoxes = $row.find('input:checked');
$checkedBoxes.each(function (i, checkbox) {
// assuming you layout the elements this way,
// we'll take advantage of .next()
var $checkbox = $(checkbox),
$line = $checkbox.next(),
$size = $line.next();
$line.val(
$family.val() + ' ' + $size.val() + ', ' + $grade.val()
);
});
});
}

And,
Yes, you can use GT for free. See the post with explanation. And look at repo on GitHub.
UPD 19.03.2019 Here is a version for browser on GitHub.
document.getElementsByName("iframe_name")[0].contentWindow.document.body.focus();
This is a recursive version (i.e. it finds the most recently updated file in a certain directory or any of its subdirectory)
find $DIR -type f -printf "%T@ %p\n" | sort -n | cut -d' ' -f 2- | tail -n 1
Edit: use -f 2-
instead of -f 2
as suggested by Kevin
This simple hack will indent the text. Works well.
select {
text-indent: 5px;
}
Another way to do that, if you want the result as a List inline, you can do it like this:
Arrays.asList(new String[] { "String1", "string2" });
The disappointing thing here is that the "X" isn't transparent (which is how I would likely create a PNG, at least).
I put together this quick test. http://jsfiddle.net/UM3a2/22/embedded/result/ which allows you to color the positive space while leaving the negative space transparent. Since it is made entirely of borders it is easy to color since border-color defaults to the text color.
It doesn't fully support I.E. 8 and earlier (border-radius issues), but it degrades to a square fairly nicely (if you're okay with a square close button).
It also requires two HTML elements since you are only allowed two pseudo elements per selector. I don't know exactly where I learned this, but I think it was in an article by Chris Coyier.
<div id="close" class="arrow-t-b">
Close
<div class="arrow-l-r"> </div>
</div>
#close {
border-width: 4px;
border-style: solid;
border-radius: 100%;
color: #333;
height: 12px;
margin:auto;
position: relative;
text-indent: -9999px;
width: 12px;
}
#close:hover {
color: #39F;
}
.arrow-t-b:after,
.arrow-t-b:before,
.arrow-l-r:after,
.arrow-l-r:before {
border-color: transparent;
border-style: solid;
border-width: 4px;
content: "";
left: 2px;
top: 0px;
position: absolute;
}
.arrow-t-b:after {
border-top-color: inherit;
}
.arrow-l-r:after {
border-right-color: inherit;
left: 4px;
top: 2px;
}
.arrow-t-b:before {
border-bottom-color: inherit;
bottom: 0;
}
.arrow-l-r:before {
border-left-color: inherit;
left: 0;
top: 2px;
}
You can use Buffer Reader from request to read
// Read from request
StringBuilder buffer = new StringBuilder();
BufferedReader reader = request.getReader();
String line;
while ((line = reader.readLine()) != null) {
buffer.append(line);
buffer.append(System.lineSeparator());
}
String data = buffer.toString()
I used a very simple function to time a part of code execution:
import time
def timing():
start_time = time.time()
return lambda x: print("[{:.2f}s] {}".format(time.time() - start_time, x))
And to use it, just call it before the code to measure to retrieve function timing, and then call the function after the code with comments. The time will appear in front of the comments. For example:
t = timing()
train = pd.read_csv('train.csv',
dtype={
'id': str,
'vendor_id': str,
'pickup_datetime': str,
'dropoff_datetime': str,
'passenger_count': int,
'pickup_longitude': np.float64,
'pickup_latitude': np.float64,
'dropoff_longitude': np.float64,
'dropoff_latitude': np.float64,
'store_and_fwd_flag': str,
'trip_duration': int,
},
parse_dates = ['pickup_datetime', 'dropoff_datetime'],
)
t("Loaded {} rows data from 'train'".format(len(train)))
Then the output will look like this:
[9.35s] Loaded 1458644 rows data from 'train'
You can also use attr
along with style
:
$('#message').attr("style", "width:550; height:300; font-size:8px" );
One simple use case when reverting change:
1. Use reset if you want to undo staging of a modified file.
2. Use checkout if you want to discard changes to unstaged file/s.
You can simply add onended="myFunction()"
to your video tag.
<video onended="myFunction()">
...
Your browser does not support the video tag.
</video>
<script type='text/javascript'>
function myFunction(){
console.log("The End.")
}
</script>
I know it is old question but I would like to help too.
Actually, we have AWS Config, which help us to search for all resources in our cloud. You can perform SQL queries too.
I really encourage you all to know this awesome service.
Or in your SQL query wrap that field with IsNull or Coalesce (SQL Server).
Either way works, I like to put that logic in the query so the report has to do less.
Try this:
$('#foo1').html($('#foo2').children().clone());
Solution: Remove STRICT_TRANS_TABLES
from sql_mode
To check your default setting,
mysql> set @@sql_mode =
'STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION';
Query OK, 0 rows affected (0.00 sec)
mysql> select @@sql_mode;
+----------------------------------------------------------------+
| @@sql_mode |
+----------------------------------------------------------------+
| STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION |
+----------------------------------------------------------------+
1 row in set (0.00 sec)
Run a sample query
mysql> INSERT INTO nb (id) VALUES(3);
ERROR 1364 (HY000): Field 'field' doesn't have a default value
Remove your STRICT_TRANS_TABLES
by resetting it to null.
mysql> set @@sql_mode = '';
Query OK, 0 rows affected (0.00 sec)
Now, run the same test query.
mysql> INSERT INTO nb (id) VALUES(3);
Query OK, 1 row affected, 1 warning (0.00 sec)

Please Try to pass parameters in httpoptions
, you can follow function below
deleteAction(url, data) {
const authToken = sessionStorage.getItem('authtoken');
const options = {
headers: new HttpHeaders({
'Content-Type': 'application/json',
Authorization: 'Bearer ' + authToken,
}),
body: data,
};
return this.client.delete(url, options);
}
I always use below approach. I've created one table in database as Table1 with only one column i.e. Row_Id Number (Long Integer) and its value is 0
INSERT INTO <TABLE_NAME_TO_RESET>
SELECT Row_Id AS <COLUMN_NAME_TO_RESET>
FROM Table1;
This will insert one row with 0 value in AutoNumber column, later delete that row.
You could build your form using FormBuilder as it let you more flexible way to configure form.
export class MyComp {
form: ControlGroup;
constructor(@Inject()fb: FormBuilder) {
this.form = fb.group({
foo: ['', MyValidators.regex(/^(?!\s|.*\s$).*$/)]
});
}
Then in your template :
<input type="text" ngControl="foo" />
<div *ngIf="!form.foo.valid">Please correct foo entry !</div>
You can also customize ng-invalid CSS class.
As there is actually no validators for regex, you have to write your own. It is a simple function that takes a control in input, and return null if valid or a StringMap if invalid.
export class MyValidators {
static regex(pattern: string): Function {
return (control: Control): {[key: string]: any} => {
return control.value.match(pattern) ? null : {pattern: true};
};
}
}
Hope that it help you.
In our case, the Windows service account that SQL Server and SQL Agent were running under were locked out in Active Directory.
try this
<iframe name="myIframe" id="myIframe" width="400px" height="400px" runat="server"></iframe>
Expose this iframe in the master page's codebehind:
public HtmlControl iframe
{
get
{
return this.myIframe;
}
}
Add the MasterType directive for the content page to strongly typed Master Page.
<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits=_Default" Title="Untitled Page" %>
<%@ MasterType VirtualPath="~/MasterPage.master" %>
In code behind
protected void Page_Load(object sender, EventArgs e)
{
this.Master.iframe.Attributes.Add("src", "some.aspx");
}
String car [];
is a reference to an array of String-s. You can't see a length because there is no array there!
Try this:
function getYesterdaysDate() {
var date = new Date();
date.setDate(date.getDate()-1);
return date.getDate() + '/' + (date.getMonth()+1) + '/' + date.getFullYear();
}
In your Activity you can tint your PNG image resources with a single colour:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
myColorTint();
setContentView(R.layout.activity_main);
}
private void myColorTint() {
int tint = Color.parseColor("#0000FF"); // R.color.blue;
PorterDuff.Mode mode = PorterDuff.Mode.SRC_ATOP;
// add your drawable resources you wish to tint to the drawables array...
int drawables[] = { R.drawable.ic_action_edit, R.drawable.ic_action_refresh };
for (int id : drawables) {
Drawable icon = getResources().getDrawable(id);
icon.setColorFilter(tint,mode);
}
}
Now when you use the R.drawable.* it should be coloured with the desired tint. If you need additional colours then you should be able to .mutate() the drawable.
Cast the value so the compiler knows which function to call:
p.setval(static_cast<const char *>( 0 ));
Note, that you have a segmentation fault in your code after you get it to compile (depending on which function you really wanted to call).
If you use the JQuery library you can use the .hover() event which merges the mouseover and mouseout event and helps you with the timing and child elements:
$(this).hover(function(){},function(){});
The first function is the start of the hover and the next is the end. Read more at: http://docs.jquery.com/Events/hover

The code below gives the HEX and RGB value of the range whether formatted using conditional formatting or otherwise. If the range is not formatted using Conditional Formatting and you intend to use iColor function in the Excel as UDF. It won't work. Read the below excerpt from MSDN.
Note that the DisplayFormat property does not work in user defined functions. For example, in a worksheet function that returns the interior color of a cell, if you use a line similar to:
Range.DisplayFormat.Interior.ColorIndex
then the worksheet function executes to return a #VALUE! error. If you are not finding color of the conditionally formatted range, then I encourage you to rather use
Range.Interior.ColorIndex
as then the function can also be used as UDF in Excel. Such as iColor(B1,"HEX")
Public Function iColor(rng As Range, Optional formatType As String) As Variant
'formatType: Hex for #RRGGBB, RGB for (R, G, B) and IDX for VBA Color Index
Dim colorVal As Variant
colorVal = rng.DisplayFormat.Interior.Color
Select Case UCase(formatType)
Case "HEX"
iColor = "#" & Format(Hex(colorVal Mod 256),"00") & _
Format(Hex((colorVal \ 256) Mod 256),"00") & _
Format(Hex((colorVal \ 65536)),"00")
Case "RGB"
iColor = Format((colorVal Mod 256),"00") & ", " & _
Format(((colorVal \ 256) Mod 256),"00") & ", " & _
Format((colorVal \ 65536),"00")
Case "IDX"
iColor = rng.Interior.ColorIndex
Case Else
iColor = colorVal
End Select
End Function
'Example use of the iColor function
Sub Get_Color_Format()
Dim rng As Range
For Each rng In Selection.Cells
rng.Offset(0, 1).Value = iColor(rng, "HEX")
rng.Offset(0, 2).Value = iColor(rng, "RGB")
Next

The easiest way to do this is with the new CSS style select
method:
soup = BeautifulSoup(html)
results = soup.select('td[valign="top"]')
With commas separating them, just like parameters without default values.
int func( int x = 0, int y = 0 );
func(); // doesn't pass optional parameters, defaults are used, x = 0 and y = 0
func(1, 2); // provides optional parameters, x = 1 and y = 2
I object the above answer and provide my own. csh
DOES have this capability and here is how it's done:
xxx |& some_exec # will pipe merged output to your some_exec
or
xxx |& cat > filename
or if you just want it to merge streams (to stdout) and not redirect to a file or some_exec:
xxx |& tee /dev/null
If your code, if the user enters 'X' (for instance), when you reach the while condition evaluation it will determine that 'X' is differente from 'n' (nChar != 'n') which will make your loop condition true and execute the code inside of your loop. The second condition is not even evaluated.
You can use the NotMapped
attribute data annotation to instruct Code-First to exclude a particular property
public class Customer
{
public int CustomerID { set; get; }
public string FirstName { set; get; }
public string LastName{ set; get; }
[NotMapped]
public int Age { set; get; }
}
[NotMapped]
attribute is included in the System.ComponentModel.DataAnnotations
namespace.
You can alternatively do this with Fluent API
overriding OnModelCreating
function in your DBContext
class:
protected override void OnModelCreating(DbModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>().Ignore(t => t.LastName);
base.OnModelCreating(modelBuilder);
}
http://msdn.microsoft.com/en-us/library/hh295847(v=vs.103).aspx
The version I checked is EF 4.3
, which is the latest stable version available when you use NuGet.
Edit : SEP 2017
Data annotation
If you are using asp.net core (2.0 at the time of this writing), The [NotMapped]
attribute can be used on the property level.
public class Customer
{
public int Id { set; get; }
public string FirstName { set; get; }
public string LastName { set; get; }
[NotMapped]
public int FullName { set; get; }
}
Fluent API
public class SchoolContext : DbContext
{
public SchoolContext(DbContextOptions<SchoolContext> options) : base(options)
{
}
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<Customer>().Ignore(t => t.FullName);
base.OnModelCreating(modelBuilder);
}
public DbSet<Customer> Customers { get; set; }
}
Another solution could be using in JSP:
<input type="hidden" id="jsonBom" value='${jsonBom}'/>
and getting the value in Javascript with jQuery:
var jsonBom = $('#jsonBom').val();
var mask = /^\d+$/;
if ( myString.exec(mask) ){
/* That's a number */
}
Increase phpMyAdmin upload / import size
By default you get a 2mb limit of upload / import size in phpmyadmin. That makes it odd and highly impossible to import larger files. You can increase the allowed upload size of phpmyadmin by editing your server’s php.ini configuration file. Usually in servers like CentOs it is located at /etc/php.ini.
Step 1: Go to php.ini and find the following and change their values to something more higher than your database size. (In this example i have used 20mb).
upload_max_filesize = 20M
post_max_size = 20M
Step2 : Restart your apache service for this new change to take effect. Usually the command to restart apache would be
service httpd restart (CentOs) / service apache2 restart (ubuntu)
You can also restart directly from their path like
/etc/init.d/apache2 restart or /etc/init.d/httpd restart
If you are in a shared hosting and do not have root access or access to your php.ini configuration file, then the other way is to create a .htaccess file in your application root and add the following line
php_value upload_max_filesize 10M
php_value post_max_size 10M
If you were still not able to increase it, please send me an email for more detailed assistance.
Add this in your web.config file
<connectionStrings>
<add name="itmall"
connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=D:\19-
02\ABCC\App_Data\abcc.mdf;Integrated Security=True;User Instance=True" />
</connectionStrings>
You can simply open the phpmyadmin page from your browser, then open any existing database -> go to Privileges tab, click on your root user and then a popup window will appear, you can set your password there.. Hope this Helps.
Make sure that this element you would like to control with z-index does not have a parent with z-index property, because element is in a lower stacking context due to its parent’s z-index level.
Here's an example:
<section class="content">
<div class="modal"></div>
</section>
<div class="side-tab"></div>
// CSS //
.content {
position: relative;
z-index: 1;
}
.modal {
position: fixed;
z-index: 100;
}
.side-tab {
position: fixed;
z-index: 5;
}
In the example above, the modal has a higher z-index than the content, although the content will appear on top of the modal because "content" is the parent with a z-index property.
Here's an article that explains 4 reasons why z-index might not work: https://coder-coder.com/z-index-isnt-working/
#compare 1st half with reversed second half
# i.e. 'abba' -> 'ab' == 'ba'[::-1]
def is_palindrome( s ):
return True if len( s ) < 2 else s[ :len( s ) // 2 ] == s[ -( len( s ) // 2 ):][::-1]
For me the UnicodeWriter
class from Python 2 CSV module documentation didn't really work as it breaks the csv.writer.write_row()
interface.
For example:
csv_writer = csv.writer(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)
works, while:
csv_writer = UnicodeWriter(csv_file)
row = ['The meaning', 42]
csv_writer.writerow(row)
will throw AttributeError: 'int' object has no attribute 'encode'
.
As UnicodeWriter
obviously expects all column values to be strings, we can convert the values ourselves and just use the default CSV module:
def to_utf8(lst):
return [unicode(elem).encode('utf-8') for elem in lst]
...
csv_writer.writerow(to_utf8(row))
Or we can even monkey-patch csv_writer to add a write_utf8_row
function - the exercise is left to the reader.

Broken pipe means you wrote to a connection that is already closed by the other end.
isConnected()
does not detect this condition. Only a write does.
is it wise to always call SocketChannel.isConnected() before attempting a SocketChannel.write()
It is pointless. The socket itself is connected. You connected it. What may not be connected is the connection itself, and you can only determine that by trying it.
Simply check that the directory/package of the class is marked as "Sources Root". I believe the package should be application or execution in your case.
To do so, right click on the package, and select Mark Directory As->Sources Root.
If the script is short and is meant to be embedded inside your script and you are running under bash
shell and also bash
shell is available on the remote side, you may use declare
to transfer local context to remote. Define variables and functions containing the state that will be transferred to the remote. Define a function that will be executed on the remote side. Then inside a here document read by bash -s
you can use declare -p
to transfer the variable values and use declare -f
to transfer function definitions to the remote.
Because declare
takes care of the quoting and will be parsed by the remote bash
, the variables are properly quoted and functions are properly transferred. You may just write the script locally, usually I do one long function with the work I need to do on the remote side. The context has to be hand-picked, but the following method is "good enough" for any short scripts and is safe - should properly handle all corner cases.
somevar="spaces or other special characters"
somevar2="!@#$%^"
another_func() {
mkdir -p "$1"
}
work() {
another_func "$somevar"
touch "$somevar"/"$somevar2"
}
ssh user@server 'bash -s' <<EOT
$(declare -p somevar somevar2) # transfer variables values
$(declare -f work another_func) # transfer function definitions
work # call the function

Automatically waits , you can also use:

How to reproduce this error, put this in a file called a.php
:
<?php
$a = 5
$b = 7; // Error happens here.
print $b;
?>
Run it:
eric@dev ~ $ php a.php
PHP Parse error: syntax error, unexpected T_VARIABLE in
/home/el/code/a.php on line 3
Explanation:
The PHP parser converts your program to a series of tokens. A T_VARIABLE
is a Token of type VARIABLE. When the parser processes tokens, it tries to make sense of them, and throws errors if it receives a variable where none is allowed.
In the simple case above with variable $b
, the parser tried to process this:
$a = 5 $b = 7;
The PHP parser looks at the $b after the 5 and says "that is unexpected".
I solved it with just using the +foo, to convert the string.
Keep in mind it's not great for readability (dirty fix).
console.log( +'1' )

Named tuples are basically easy-to-create, lightweight object types. Named tuple instances can be referenced using object-like variable dereferencing or the standard tuple syntax. They can be used similarly to struct
or other common record types, except that they are immutable. They were added in Python 2.6 and Python 3.0, although there is a recipe for implementation in Python 2.4.
For example, it is common to represent a point as a tuple (x, y)
. This leads to code like the following:
pt1 = (1.0, 5.0)
pt2 = (2.5, 1.5)
from math import sqrt
line_length = sqrt((pt1[0]-pt2[0])**2 + (pt1[1]-pt2[1])**2)
Using a named tuple it becomes more readable:
from collections import namedtuple
Point = namedtuple('Point', 'x y')
pt1 = Point(1.0, 5.0)
pt2 = Point(2.5, 1.5)
from math import sqrt
line_length = sqrt((pt1.x-pt2.x)**2 + (pt1.y-pt2.y)**2)
However, named tuples are still backwards compatible with normal tuples, so the following will still work:
Point = namedtuple('Point', 'x y')
pt1 = Point(1.0, 5.0)
pt2 = Point(2.5, 1.5)
from math import sqrt
# use index referencing
line_length = sqrt((pt1[0]-pt2[0])**2 + (pt1[1]-pt2[1])**2)
# use tuple unpacking
x1, y1 = pt1
Thus, you should use named tuples instead of tuples anywhere you think object notation will make your code more pythonic and more easily readable. I personally have started using them to represent very simple value types, particularly when passing them as parameters to functions. It makes the functions more readable, without seeing the context of the tuple packing.
Furthermore, you can also replace ordinary immutable classes that have no functions, only fields with them. You can even use your named tuple types as base classes:
class Point(namedtuple('Point', 'x y')):
[...]
However, as with tuples, attributes in named tuples are immutable:
>>> Point = namedtuple('Point', 'x y')
>>> pt1 = Point(1.0, 5.0)
>>> pt1.x = 2.0

If you want to be able change the values, you need another type. There is a handy recipe for mutable recordtypes which allow you to set new values to attributes.
>>> from rcdtype import *
>>> Point = recordtype('Point', 'x y')
>>> pt1 = Point(1.0, 5.0)
>>> pt1 = Point(1.0, 5.0)
>>> pt1.x = 2.0
>>> print(pt1[0])
2.0
I am not aware of any form of "named list" that lets you add new fields, however. You may just want to use a dictionary in this situation. Named tuples can be converted to dictionaries using pt1._asdict()
which returns {'x': 1.0, 'y': 5.0}
and can be operated upon with all the usual dictionary functions.
As already noted, you should check the documentation for more information from which these examples were constructed.
I found that I needed to group by the month and year so neither of the above worked for me. Instead I used date_format
SELECT date
FROM blog
GROUP BY DATE_FORMAT(date, "%m-%y")
ORDER BY YEAR(date) DESC, MONTH(date) DESC
I use this alert

This problem occurs when the controller or directive are not specified as a array of dependencies and function. For example
angular.module("appName").directive('directiveName', function () {
return {
restrict: 'AE',
templateUrl: 'calender.html',
controller: function ($scope) {
$scope.selectThisOption = function () {
// some code
};
}
};
});
When minified The '$scope' passed to the controller function is replaced by a single letter variable name . This will render angular clueless of the dependency . To avoid this pass the dependency name along with the function as a array.
angular.module("appName").directive('directiveName', function () {
return {
restrict: 'AE',
templateUrl: 'calender.html'
controller: ['$scope', function ($scope) { //<-- difference
$scope.selectThisOption = function () {
// some code
};
}]
};
});
From documentation:
Matplotlib can only read PNGs natively. Further image formats are supported via the optional dependency on Pillow.
So in case of PNG
we may use plt.imread()
. In other cases it's probably better to use Pillow
directly.
If the project is Maven, you can try this way :
Then the import issue should be solved .
In my case you should put the function in $(document).ready
$(document).ready(function () {
$('div#page').on('scroll', function () {
...
});
});
In order to make font-size fit its container, rather than the window, see the resizeFont()
function I have shared in this question (a combination of other answers, most of which are already linked here). It is triggered using window.addEventListener('resize', resizeFont);
.
Vanilla JavaScript: Resize font-awesome to fit container
function resizeFont() {
var elements = document.getElementsByClassName('resize');
console.log(elements);
if (elements.length < 0) {
return;
}
_len = elements.length;
for (_i = 0; _i < _len; _i++) {
var el = elements[_i];
el.style.fontSize = "100%";
for (var size = 100; el.scrollHeight > el.clientHeight; size -= 10) {
el.style.fontSize = size + '%';
}
}
}
You could perhaps use vw/vh as a fallback, so you dynamically assign em
or rem
units using JavaScript, ensuring that the fonts do scale to the window if JavaScript is disabled.
Apply the .resize
class to all elements containing text you wish to be scaled.
Trigger the function prior to adding the window resize event listener. Then, any text which doesn't fit its container will be scaled down when the page loads, as well as when it is resized.
NOTE: The default font-size
must be set to either em
,rem
or %
to achieve proper results.
I remember my CompSci professor saying never to use floats for currency.
The reason for that is how the IEEE specification defines floats in binary format. Basically, it stores sign, fraction and exponent to represent a Float. It's like a scientific notation for binary (something like +1.43*10^2
). Because of that, it is impossible to store fractions and decimals in Float exactly.
That's why there is a Decimal format. If you do this:
irb:001:0> "%.47f" % (1.0/10)
=> "0.10000000000000000555111512312578270211815834045" # not "0.1"!
whereas if you just do
irb:002:0> (1.0/10).to_s
=> "0.1" # the interprer rounds the number for you
So if you are dealing with small fractions, like compounding interests, or maybe even geolocation, I would highly recommend Decimal format, since in decimal format 1.0/10
is exactly 0.1.
However, it should be noted that despite being less accurate, floats are processed faster. Here's a benchmark:
require "benchmark"
require "bigdecimal"
d = BigDecimal.new(3)
f = Float(3)
time_decimal = Benchmark.measure{ (1..10000000).each { |i| d * d } }
time_float = Benchmark.measure{ (1..10000000).each { |i| f * f } }
puts time_decimal
#=> 6.770960 seconds
puts time_float
#=> 0.988070 seconds
Use float when you don't care about precision too much. For example, some scientific simulations and calculations only need up to 3 or 4 significant digits. This is useful in trading off accuracy for speed. Since they don't need precision as much as speed, they would use float.
Use decimal if you are dealing with numbers that need to be precise and sum up to correct number (like compounding interests and money-related things). Remember: if you need precision, then you should always use decimal.
There doesn't seem to be justify-self
, but you can achieve similar result setting appropriate margin
to auto
¹. E. g. for flex-direction: row
(default) you should set margin-right: auto
to align the child to the left.

height: 100px;_x000D_
border: solid 10px skyblue;_x000D_
_x000D_

justify-content: flex-end;_x000D_
}_x000D_
.block {_x000D_
width: 50px;_x000D_
background: tomato;_x000D_
}_x000D_
.justify-start {_x000D_
margin-right: auto;_x000D_
}
_x000D_
<div class="container">_x000D_
<div class="block justify-start"></div>_x000D_
<div class="block"></div>_x000D_
</div>
_x000D_

Is there a reason you couldn't select your results and right click and choose Advanced Copy -> Advanced Copy? I'm on a Mac and this is how I always copy results to the clipboard for pasting.
I know you're talking about MySQL, but anyway: In Oracle 9 explicit joins and implicit joins would generate different execution plans. AFAIK that has been solved in Oracle 10+: there's no such difference anymore.
Try using the overflow
CSS property. There are also separate properties to define the behaviour of just horizontal overflow (overflow-x
) and vertical overflow (overflow-y
).
Since you only want the vertical scroll, try this:
table {
height: 500px;
overflow-y: scroll;
}
EDIT:
Apparently <table>
elements don't respect the overflow
property. This appears to be because <table>
elements are not rendered as display: block
by default (they actually have their own display type). You can force the overflow
property to work by setting the <table>
element to be a block type:
table {
display: block;
height: 500px;
overflow-y: scroll;
}
Note that this will cause the element to have 100% width, so if you don't want it to take up the entire horizontal width of the page, you need to specify an explicit width for the element as well.
Flexboxes can accomplish this by using align-items: flex-end;
with display: flex;
or display: inline-flex;
div#imageContainer {
height: 160px;
align-items: flex-end;
display: flex;
/* This is the default value, so you only need to explicitly set it if it's already being set to something else elsewhere. */
/*flex-direction: row;*/
}
The other issue here lies under Code Signing Identity under the Build Settings. Be sure that it contains the Code Signing Identity: "iOS Developer" as opposed to "Don't Code Sign." This will allow you to deploy it to your iOS device. Especially, if you have downloaded a GitHub example or something to this effect.
In recent browser, you can use filter
var size = arr.filter(function(value) { return value !== undefined }).length;
console.log(size);
Another method, if the browser supports indexOf for arrays:
var size = arr.slice(0).sort().indexOf(undefined);
If for absurd you have one-digit-only elements in the array, you could use that dirty trick:
console.log(arr.join("").length);
There are several methods you can use, but at the end we have to see if it's really worthy doing these instead of a loop.
Try the SetField method:
table.Rows[i].SetField(column, value);
table.Rows[i].SetField(columnIndex, value);
table.Rows[i].SetField(columnName, value);
This should get the job done and is a bit "cleaner" than using Rows[i][j].
The following works with a relative path to an image into a subfolder next to the document (currently only tested on a Windows System):
![image info](./pictures/image.png)
This worked for me. Others might find it useful.

If you are reencoding in your ffmpeg command line, that may be the reason why it is CPU intensive. You need to simply copy the streams to the single container. Since I do not have your command line I cannot suggest a specific improvement here. Your acodec and vcodec should be set to copy is all I can say.
EDIT: On seeing your command line and given you have already tried it, this is for the benefit of others who come across the same question. The command:
ffmpeg -i rtsp://@192.168.241.1:62156 -acodec copy -vcodec copy c:/abc.mp4
will not do transcoding and dump the file for you in an mp4. Of course this is assuming the streamed contents are compatible with an mp4 (which in all probability they are).
You can see in this List of useful HTTP headers.
X-XSS-Protection: This header enables the Cross-site scripting (XSS) filter built into most recent web browsers. It's usually enabled by default anyway, so the role of this header is to re-enable the filter for this particular website if it was disabled by the user. This header is supported in IE 8+, and in Chrome (not sure which versions). The anti-XSS filter was added in Chrome 4. Its unknown if that version honored this header.
There is no way to delete or read the past history.
You could try going around it by emulating history in your own memory and calling history.pushState
everytime window popstate
event is emitted (which is proposed by the currently accepted Mike's answer), but it has a lot of disadvantages that will result in even worse UX than not supporting the browser history at all in your dynamic web app, because:
So even if you try going around it by building virtual history, it's very likely that it can also lead into a situation where you have blank history states (to which going back/forward does nothing), or where that going back/forward skips some of your history states totally.
Removing Space-:

style: new TextStyle(color: Color(0xFF2E3233))),
onTap: () {},
),
GestureDetector(
onTap: (){},
child: new Text(

You can also use the special word like

Debug.Print ("Found ','")

Well, this is already in 2018 but I think it is better late than never (like a title in a TV program), lol. Down here is the jQuery code that I create during my thesis.
<script type="text/javascript">
$(document).ready(function(){
$('a[data-toggle="tab"]').on('show.affectedDiv.tab', function(e) {
localStorage.setItem('activeTab', $(e.target).attr('href'));
});
var activeTab = localStorage.getItem('activeTab');
if(activeTab){
$('#myTab a[href="' + activeTab + '"]').tab('show');
}
});
</script>
and here is the code for bootstrap tabs:
<div class="affectedDiv">
<ul class="nav nav-tabs" id="myTab">
<li class="active"><a data-toggle="tab" href="#sectionA">Section A</a></li>
<li><a data-toggle="tab" href="#sectionB">Section B</a></li>
<li><a data-toggle="tab" href="#sectionC">Section C</a></li>
</ul>
<div class="tab-content">
<div id="sectionA" class="tab-pane fade in active">
<h3>Section A</h3>
<p>Aliquip placeat salvia cillum iphone. Seitan aliquip quis cardigan american apparel, butcher voluptate nisi qui. Raw denim you probably haven't heard of them jean shorts Austin.

Dont forget to call the bootstrap and other fundamental things
here are quick codes for you:
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
Now let's come to the explanation:
The jQuery code in the above example simply gets the element's href attribute value when a new tab has been shown using the jQuery .attr() method and save it locally in the user's browser through HTML5 localStorage object. Later, when the user refresh the page it retrieves this data and activate the related tab via .tab('show') method.

The LDF is the transaction log. It keeps a record of everything done to the database for rollback purposes.
You do not want to delete, but you can shrink it with the dbcc shrinkfile
command. You can also right-click on the database in SQL Server Management Studio and go to Tasks > Shrink.
I found same problem, we can resolve in three steps:-
Step 1
sudo chown -R $(whoami) $(brew --prefix)/*
Step 2
brew doctor
Step 3
brew prune
If you still get any linking problem, lets say for mysql
, just write
brew link mysql
This will work.

If id
is the first key in the array, this'll do:
$ids = array_map('current', $users);
You should not necessarily rely on this though. :)
You can use a defaultdict for this.
from collections import defaultdict
d = defaultdict(list)
d['key'].append('mykey')
This is slightly more efficient than setdefault
since you don't end up creating new lists that you don't end up using. Every call to setdefault
is going to create a new list, even if the item already exists in the dictionary.
See Is there a clean wikipedia API just for retrieve content summary? for other proposed solutions. Here is one that I suggested:
There is actually a very nice prop called extracts that can be used with queries designed specifically for this purpose. Extracts allow you to get article extracts (truncated article text). There is a parameter called exintro that can be used to retrieve the text in the zeroth section (no additional assets like images or infoboxes). You can also retrieve extracts with finer granularity such as by a certain number of characters (exchars) or by a certain number of sentences(exsentences)
Here is a sample query http://en.wikipedia.org/w/api.php?action=query&prop=extracts&format=json&exintro=&titles=Stack%20Overflow and the API sandbox http://en.wikipedia.org/wiki/Special:ApiSandbox#action=query&prop=extracts&format=json&exintro=&titles=Stack%20Overflow to experiment more with this query.
Please note that if you want the first paragraph specifically you still need to get the first tag. However in this API call there are no additional assets like images to parse. If you are satisfied with this intro summary you can retrieve the text by running a function like php's strip_tag that remove the html tags.
You can print some text by using SELECT
command like that:
SELECT 'some text'
Result:
+-----------+
| some text |
+-----------+
| some text |
+-----------+
1 row in set (0.02 sec)
You can try this:
if(document.documentMode) {
document.documentElement.className+=' ie'+document.documentMode;
}
I'd stay well away from using MAC addresses. On some hardware, the MAC address can change when you reboot. We learned quite early during our research not to rely on it.
Take a look at the article Developing for Software Protection and Licensing which has some pointers on how to design & implement apps to reduce piracy.
Obligatory disclaimer & plug: the company I co-founded produces the OffByZero Cobalt licensing solution. So it probably won't surprise you to hear that I recommend outsourcing your licensing, & focusing on your core competencies.
This has a good general description: https://gephi.wordpress.com/tag/maven/
Let me make a few statement that can put the difference in focus:
We migrated our code base from Ant to Maven
All 3rd party librairies have been uploaded to Nexus. Maven is using Nexus as a source for libraries.
Basic functionalities of a repository manager like Sonatype are:
def get_client_ip(request):
x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR')
if x_forwarded_for:
ip = x_forwarded_for.split(',')[0]
else:
ip = request.META.get('REMOTE_ADDR')
return ip
Make sure you have reverse proxy (if any) configured correctly (e.g. mod_rpaf
installed for Apache).
Note: the above uses the first item in X-Forwarded-For
, but you might want to use the last item (e.g., in the case of Heroku: Get client's real IP address on Heroku)
And then just pass the request as argument to it;
get_client_ip(request)
Remember that a single =
is always an assignment in C or C++.
Your test should be if ( match == 0 && k == M )
you made a typo on the k == M
test.
If you really mean k=M
(i.e. a side-effecting assignment inside a test) you should for readability reasons code if (match == 0 && (k=m) != 0)
but most coding rules advise not writing that.
BTW, your mistake suggests to ask for all warnings (e.g. -Wall
option to g++
), and to upgrade to recent compilers. The next GCC 4.8 will give you:
% g++-trunk -Wall -c ederman.cc
ederman.cc: In function ‘void foo()’:
ederman.cc:9:30: error: lvalue required as left operand of assignment
if ( match == 0 && k = M )
^
and Clang 3.1 also tells you ederman.cc:9:30: error: expression is not assignable
So use recent versions of free compilers and enable all the warnings when using them.
"Unable to load the requested file"
Can be also caused by access permissions under linux , make sure you set the correct read permissions for the directory "views/home"
As already explained by the other contributers, you could print out the counter and then replace the return with a break statement.
N = int(input("enter a positive integer:"))
counter = 1
while (N > 0):
counter = counter * N
N = N - 1
print(counter)
break
You can always check the latest gradle plugin version here: https://bintray.com/android/android-tools/com.android.tools.build.gradle
So as of today you should use:
classpath 'com.android.tools.build:gradle:2.2.2'
accordingly.
N+1 SELECT problem is really hard to spot, especially in projects with large domain, to the moment when it starts degrading the performance. Even if the problem is fixed i.e. by adding eager loading, a further development may break the solution and/or introduce N+1 SELECT problem again in other places.
I've created open source library jplusone to address those problems in JPA based Spring Boot Java applications. The library provides two major features:

Browser have cross domain security at client side which verify that server allowed to fetch data from your domain. If Access-Control-Allow-Origin
not available in response header, browser disallow to use response in your JavaScript code and throw exception at network level. You need to configure cors
at your server side.
You can fetch request using mode: 'cors'
. In this situation browser will not throw execption for cross domain, but browser will not give response in your javascript function.
So in both condition you need to configure cors
in your server or you need to use custom proxy server.
Looks like MySQLdb doesn't actually provide a translation for that API call. The relevant C API call is mysql_fetch_fields
, and there is no MySQLdb translation for that
In my case there was a race, as I needed the ajax response to fill a hidden field and send the form after it's filled. I fixed it with putting e.preventDefault() into a condition.
var all_is_done=false;
$("form").submit(function(e){
if(all_is_done==false){
e.preventDefault();
do_the_stuff();
}
});
function do_the_stuf(){
//do stuff
all_is_done=true;
$("form").submit();
}
Class<?> cls = Class.forName(className);
But your className
should be fully-qualified - i.e. com.mycompany.MyClass
If you know the format of date in $_POST[intake_date] you can use explode to get year , month and time and then concatenate to form a valid mySql date. for example if you are getting something like 12/15/1988 in date you can do like this
$date = explode($_POST['intake_date'], '/');
mysql_date = $date[2].'-'$date[1].'-'$date[0];
though if you have valid date date('y-m-d', strtotime($date)); should also work
