You probably want to have a list of supported encodings. For each file, try each encoding in turn, maybe starting with UTF-8. Every time you catch the MalformedInputException
, try the next encoding.
Use:
BEGIN
PACKAGE_NAME.PROCEDURE_NAME(parameter_value, ...);
END;
Replace "PACKAGE_NAME", "PROCEDURE_NAME", and "parameter_value" with what you need. OUT parameters will need to be declared prior to.
This should work:
$tmpfile = $_FILES['image']['tmp_name'];
$filename = basename($_FILES['image']['name']);
$data = array(
'uploaded_file' => '@'.$tmpfile.';filename='.$filename,
);
$ch = curl_init();
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
// set your other cURL options here (url, etc.)
curl_exec($ch);
In the receiving script, you would have:
print_r($_FILES);
/* which would output something like
Array (
[uploaded_file] => Array (
[tmp_name] => /tmp/f87453hf
[name] => myimage.jpg
[error] => 0
[size] => 12345
[type] => image/jpeg
)
)
*/
Then, if you want to properly handle the file upload, you would do something like this:
if (move_uploaded_file($_FILES['uploaded_file'], '/path/to/destination/file.zip')) {
// do stuff
}
you installed Xampp-VM (VirtualMachine), simply instead install one of the "normal" installations and everything runs fine.
Please make sure that compileSdkVersion
, buildToolsVersion
and targetSdkVersion
have the same version number. I also have this error because it has different version. This solution worked for me.
I hope it can help you all.
os.walk is the answer, this will find the first match:
import os
def find(name, path):
for root, dirs, files in os.walk(path):
if name in files:
return os.path.join(root, name)
And this will find all matches:
def find_all(name, path):
result = []
for root, dirs, files in os.walk(path):
if name in files:
result.append(os.path.join(root, name))
return result
And this will match a pattern:
import os, fnmatch
def find(pattern, path):
result = []
for root, dirs, files in os.walk(path):
for name in files:
if fnmatch.fnmatch(name, pattern):
result.append(os.path.join(root, name))
return result
find('*.txt', '/path/to/dir')
Sometimes it's easier to think in terms of which fields to exclude.
If the number of fields not being cut (not being retained in the output) is small, it may be easier to use the --complement
flag, e.g. to include all fields 1-20 except not 3, 7, and 12 -- do this:
cut -d, --complement -f3,7,12 <inputfile
Rather than
cut -d, -f-2,4-6,8-11,13-
render: ->
<a className="upvotes" onClick={(e) => {this.upvote(e); }}>upvote</a>
For anyone looking to do this dynamically then setCompoundDrawables(Drawable left, Drawable top, Drawable right, Drawable bottom)
on the buttons object will assist.
Sample
Button search = (Button) findViewById(R.id.yoursearchbutton);
search.setCompoundDrawables('your_drawable',null,null,null);
If your command pip install --upgrade tensorflow
compiles, then your version of tensorflow should be the newest. I personally prefer to use anaconda
. You can easily install and upgrade tensorflow as follows:
conda install -c conda-forge tensorflow # to install
conda upgrade -c conda-forge tensorflow # to upgrade
Also if you want to use it with your GPU you have an easy install:
conda install -c anaconda tensorflow-gpu
I've been using it for a while now and I have never had any problem.
Current thinking seems to be to "tolerate" nulls, that is, to allow them in general, although some operations are less tolerant and may end up throwing NPE. See the discussion of nulls on the Lambda Libraries expert group mailing list, specifically this message. Consensus around option #3 subsequently emerged (with a notable objection from Doug Lea). So yes, the OP's concern about pipelines blowing up with NPE is valid.
It's not for nothing that Tony Hoare referred to nulls as the "Billion Dollar Mistake." Dealing with nulls is a real pain. Even with classic collections (without considering lambdas or streams) nulls are problematic. As fge mentioned in a comment, some collections allow nulls and others do not. With collections that allow nulls, this introduces ambiguities into the API. For example, with Map.get(), a null return indicates either that the key is present and its value is null, or that the key is absent. One has to do extra work to disambiguate these cases.
The usual use for null is to denote the absence of a value. The approach for dealing with this proposed for Java SE 8 is to introduce a new java.util.Optional
type, which encapsulates the presence/absence of a value, along with behaviors of supplying a default value, or throwing an exception, or calling a function, etc. if the value is absent. Optional
is used only by new APIs, though, everything else in the system still has to put up with the possibility of nulls.
My advice is to avoid actual null references to the greatest extent possible. It's hard to see from the example given how there could be a "null" Otter. But if one were necessary, the OP's suggestions of filtering out null values, or mapping them to a sentinel object (the Null Object Pattern) are fine approaches.
Just do it the usual way and then insert it using SecurityContextHolder.setContext()
in your test class, for example:
Controller:
Authentication a = SecurityContextHolder.getContext().getAuthentication();
Test:
Authentication authentication = Mockito.mock(Authentication.class);
// Mockito.whens() for your authorization object
SecurityContext securityContext = Mockito.mock(SecurityContext.class);
Mockito.when(securityContext.getAuthentication()).thenReturn(authentication);
SecurityContextHolder.setContext(securityContext);
Here is a solution modified from Cruz Nunez's solution above.
// Used to format phone number
function phoneFormatter() {
$('.phone').on('input', function() {
var number = $(this).val().replace(/[^\d]/g, '')
if (number.length < 7) {
number = number.replace(/(\d{0,3})(\d{0,3})/, "($1) $2");
} else if (number.length <= 10) {
number = number.replace(/(\d{3})(\d{3})(\d{1,4})/, "($1) $2-$3");
} else {
// ignore additional digits
number = number.replace(/(\d{3})(\d{1,3})(\d{1,4})(\d.*)/, "($1) $2-$3");
}
$(this).val(number)
});
};
$(phoneFormatter);
In this solution, the formatting is applied no matter how many digits the user has entered. (In Nunes' solution, the formatting is applied only when exactly 7 or 10 digits has been entered.)
It requires the zip code for a 10-digit US phone number to be entered.
Both solutions, however, editing already entered digits is problematic, as typed digits always get added to the end.
I recommend, instead, the robust jQuery Mask Plugin code, mentioned below:
I recommend using jQuery Mask Plugin (page has live examples), on github.
These links have minimal explanations on how to use:
CDN
Instead of installing/hosting the code, you can also add a link to a CDN of the script
CDN Link for jQuery Mask Plugin
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery.mask/1.14.16/jquery.mask.min.js" integrity="sha512-pHVGpX7F/27yZ0ISY+VVjyULApbDlD0/X0rgGbTqCE7WFW5MezNTWG/dnhtbBuICzsd0WQPgpE4REBLv+UqChw==" crossorigin="anonymous"></script>

If you are using Contact Form 7 plugin on a WordPress site, the easiest option to control form fields is if you can simply add a class to your input field to take care of it for you.
Masks Form Fields plugin is one option that makes this easy to do.
I like this option, as, Internally, it embeds a minimized version of the code from jQuery Mask Plugin mentioned above.
Example usage on a Contact Form 7 form:
<label> Your Phone Number (required)
[tel* customer-phone class:phone_us minlength:14 placeholder "(555) 555-5555"]
</label>
The important part here is class:phone_us
.
Note that if you use minlength
/maxlength
, the length must include the mask characters, in addition to the digits.
Just need to add font-size: 0;
to your element that contains text.
This works well.
Html (you'll have to put the onclick attribute on every input you want it to work for on the page)
<input type="text" value="click the input to select" onclick="this.select();"/>
OR A BETTER OPTION
jQuery (this will work for every text input on the page, no need to change your html):
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.js"></script>
<script type="text/javascript">
$(function(){
$(document).on('click','input[type=text]',function(){ this.select(); });
});
</script>
I suggest split (not saying that the other answers are invalid, this is just another way to do it):
def findreplace(char, string):
return ''.join(string.split(char))
Splitting by a character removes all the characters and turns it into a list. Then we join the list with the join function. You can see the ipython console test below
In[112]: findreplace('i', 'it is icy')
Out[112]: 't s cy'
And the speed...
In[114]: timeit("findreplace('it is icy','i')", "from __main__ import findreplace")
Out[114]: 0.9927914671134204
Not as fast as replace or translate, but ok.

Yes, but it also means hash(b) == hash(x)
, so equality of the items isn't enough to make them the same.
By either escaping those characters with htmlspecialchars
, or, perhaps more appropriately, using a library for building XML documents, such as DOMDocument or XMLWriter.
Another alternative would be to use CDATA sections, but then you'd have to look out for occurrences of ]]>
.
Take also into consideration that that you must respect the encoding you define for the XML document (by default UTF-8).
you can use
return false;
or return;
within your condition.
function refreshGrid(entity) {
var store = window.localStorage;
var partitionKey;
....
if(some_condition) {
return false;
}

}
if($level > self::MAX_LEVEL) {
throw new OverflowException(sprintf('%s stack overflow: %d exceeds max recursion level', __METHOD__, $level));
}
$o = new stdClass();
foreach($a as $key => $value) {

As of Java 9, the JDK includes jshell
, a Java REPL.
Assuming the JDK 9+ bin
directory is correctly added to your path, you will be able to simply:
jshell File.java
— File.java
being your file of course. main
method: jshell> File.main(null)
./exit
Full documentation for JShell can be found here.
You can do something like this:
.flex {_x000D_
display: flex;_x000D_
flex-direction: row;_x000D_
flex-wrap: wrap;_x000D_
}_x000D_
_x000D_
.flex>div {_x000D_
flex: 1 0 50%;_x000D_
}_x000D_
_x000D_
.flex>div:first-child {_x000D_
flex: 0 1 100%;_x000D_
}
_x000D_
<div class="flex">_x000D_
<div>Hi</div>_x000D_
<div>Hello</div>_x000D_
<div>Hello 2</div>_x000D_
</div>
_x000D_
Here is a demo: http://jsfiddle.net/73574emn/1/
This model relies on the line-wrap after one "row" is full. Since we set the first item's flex-basis
to be 100% it fills the first row completely. Special attention on the flex-wrap: wrap;
The syntax of ng-style
is not quite that. It accepts a dictionary of keys (attribute names) and values (the value they should take, an empty string unsets them) rather than only a string. I think what you want is this:
<div ng-style="{ 'width' : width, 'background' : bgColor }"></div>
And then in your controller:
$scope.width = '900px';
$scope.bgColor = 'red';
This preserves the separation of template and the controller: the controller holds the semantic values while the template maps them to the correct attribute name.

You have to create an object. Assign the values to the object. Then push it into the array:

I have same problem because option In-App Purchase
was ON
in project's Capabilities
. If your app is not need in-app purchases - turn it off, or you need to set a correct provision profile to Debug
scheme.
For my case, I Tried all above method, and none works. However I solve the problem now. Here's my trick:
In Control Panel -> "Programs" -> "Turn Windows features on or off" (under "Programs and Features") and I try to locate "Hyper-V", but I cannot locate "Hyper-V", however I have "Windows Virtual PC", and I suspect they are the same thing, so I disable it, reboot, and it works!

Good luck finding a font that supports them all. Only one shows up in Windows 7 with Chrome.
What about this:
int[] a = {1,2,3};
Integer[] b = ArrayUtils.toObject(a);
List<Integer> c = Arrays.asList(b);
You can alias the column names one by one, like so
SELECT col1 as `MyNameForCol1`, col2 as `MyNameForCol2`
FROM `foobar`
Edit You can access INFORMATION_SCHEMA.COLUMNS
directly to mangle a new alias like so. However, how you fit this into a query is beyond my MySql skills :(
select CONCAT('Foobar_', COLUMN_NAME)
from INFORMATION_SCHEMA.COLUMNS
where TABLE_NAME = 'Foobar'

The difference is that Any is an extension method for any IEnumerable<T>
defined on System.Linq.Enumerable. It can be used on any IEnumerable<T>
instance.
Exists does not appear to be an extension method. My guess is that coll is of type List<T>
. If so Exists is an instance method which functions very similar to Any.
In short, the methods are essentially the same. One is more general than the other.
Your question title and your question body are different. Ruby does not have a starts_with? method. Rails, which is a Ruby framework, however, does, as sepp2k states. See his comment on his answer for the link to the documentation for it.
You could always use a regular expression though:
if SomeString.match(/^abc/)
# SomeString starts with abc
^
means "start of string" in regular expressions
Think of a jar file as the root of a directory structure. Yes, you need to add them all separately.
You might want to look here and here.
A Little code example from the first link:
<?php
// include the SOAP classes
require_once('nusoap.php');
// define parameter array (ISBN number)
$param = array('isbn'=>'0385503954');
// define path to server application
$serverpath ='http://services.xmethods.net:80/soap/servlet/rpcrouter';
//define method namespace
$namespace="urn:xmethods-BNPriceCheck";
// create client object
$client = new soapclient($serverpath);
// make the call
$price = $client->call('getPrice',$param,$namespace);
// if a fault occurred, output error info
if (isset($fault)) {
print "Error: ". $fault;
}
else if ($price == -1) {
print "The book is not in the database.";
} else {
// otherwise output the result
print "The price of book number ". $param[isbn] ." is $". $price;
}
// kill object
unset($client);
?>
If you want a real timer you need to use the date object.
Calculate the difference.
Format your string.
window.onload=function(){
var start=Date.now(),r=document.getElementById('r');
(function f(){
var diff=Date.now()-start,ns=(((3e5-diff)/1e3)>>0),m=(ns/60)>>0,s=ns-m*60;
r.textContent="Registration closes in "+m+':'+((''+s).length>1?'':'0')+s;
if(diff>3e5){
start=Date.now()
}
setTimeout(f,1e3);
})();
}
Example
not so precise timer
var time=5*60,r=document.getElementById('r'),tmp=time;
setInterval(function(){
var c=tmp--,m=(c/60)>>0,s=(c-m*60)+'';
r.textContent='Registration closes in '+m+':'+(s.length>1?'':'0')+s
tmp!=0||(tmp=time);
},1000);
check window.history.length
or simply, history.length
EDIT: some browsers start their history with 0, others with 1. adjust accordingly.
if it has a value of 1, it means it's the first page in that window/tab - then you can have JS redirect you.
<script>
function backAway(){
//if it was the first page
if(history.length === 1){
window.location = "http://www.mysite.com/"
} else {
history.back();
}
}
</script>
<a href="#" onClick="backAway()">Back</a>
I wanted a solution to copy files modified after a certain date and time which mean't I need to use Get-ChildItem piped through a filter. Below is what I came up with:

$ArchiveFolder = "J:\Temp\Robin\Deploy\MyProject"
$ChangesStarted = New-Object System.DateTime(2013,10,16,11,0,0)
$IncludeFiles = ("*.vb","*.cs","*.aspx","*.js","*.css")
Get-ChildItem $SourceFolder -Recurse -Include $IncludeFiles | Where-Object {$_.LastWriteTime -gt $ChangesStarted} | ForEach-Object {
$PathArray = $_.FullName.Replace($SourceFolder,"").ToString().Split('\')
$Folder = $ArchiveFolder
for ($i=1; $i -lt $PathArray.length-1; $i++) {

Think of the phrase in the square brackets as a WHERE clause in SQL.
So this query says, "select the "href" attribute (@) of an "a" tag that appears anywhere (//), but only where (the bracketed phrase) the textual contents of the "a" tag is equal to 'programming questions site'".
Make sure you are sending the proper parameters too. This happened to me after switching to UI-Router.
To fix it, I changed $routeParams to use $stateParams in my controller. The main issue was that $stateParams was no longer sending a proper parameter to the resource.
You can use importlib to import modules where you want to import a module from a folder using a string like so:
import importlib
scriptName = 'Snake'
script = importlib.import_module('Scripts\\.%s' % scriptName)
This example has a main.py which is the above code then a folder called Scripts and then you can call whatever you need from this folder by changing the scriptName
variable. You can then use script
to reference to this module. such as if I have a function called Hello()
in the Snake module you can run this function by doing so:
script.Hello()
I have tested this in Python 3.6
Views are essentially logical table-like structures populated on the fly by a given query. The results of a view query are not stored anywhere on disk and the view is recreated every time the query is executed. Materialized views are actual structures stored within the database and written to disk. They are updated based on the parameters defined when they are created.
First of all, why is the map a HashMap<String, ArrayList<String>>
and not a HashMap<String, List<String>>
? Is there some reason why the value must be a specific implementation of interface List
(ArrayList
in this case)?
Arrays.asList
does not return a java.util.ArrayList
, so you can't assign the return value of Arrays.asList
to a variable of type ArrayList
.
Instead of:
allWords = Arrays.asList(strTemp.toLowerCase().split("\\s+"));
Try this:
allWords.addAll(Arrays.asList(strTemp.toLowerCase().split("\\s+")));
I want to understand the lock each transaction isolation takes on the table
For example, you have 3 concurrent processes A, B and C. A starts a transaction, writes data and commit/rollback (depending on results). B just executes a SELECT
statement to read data. C reads and updates data. All these process work on the same table T.
WHERE aField > 10 AND aField < 20
, A inserts data where aField
value is between 10 and 20, then B reads the data again and get a different result.I want to understand where we define these isolation levels: only at JDBC/hibernate level or in DB also
Using JDBC, you define it using Connection#setTransactionIsolation
.
Using Hibernate:
<property name="hibernate.connection.isolation">2</property>
Where
Hibernate configuration is taken from here (sorry, it's in Spanish).
By the way, you can set the isolation level on RDBMS as well:
SET ISOLATION TO DIRTY READ
sentence.)and on and on...
And if you want to vary the speed and include callbacks simply add them like this :
jQuery.fn.extend({
slideRightShow: function(speed,callback) {
return this.each(function() {
$(this).show('slide', {direction: 'right'}, speed, callback);
});
},
slideLeftHide: function(speed,callback) {
return this.each(function() {
$(this).hide('slide', {direction: 'left'}, speed, callback);
});
},
slideRightHide: function(speed,callback) {
return this.each(function() {
$(this).hide('slide', {direction: 'right'}, speed, callback);
});
},
slideLeftShow: function(speed,callback) {
return this.each(function() {
$(this).show('slide', {direction: 'left'}, speed, callback);
});
}
});
try this
Execute this SQL:
SHOW TABLE STATUS LIKE '<tablename>'
and fetch the value of the field Auto_increment
As of C++11, you have two major additional options. First, you can use insert()
with list initialization syntax:
function.insert({0, 42});
This is functionally equivalent to
function.insert(std::map<int, int>::value_type(0, 42));
but much more concise and readable. As other answers have noted, this has several advantages over the other forms:
operator[]
approach requires the mapped type to be assignable, which isn't always the case.operator[]
approach can overwrite existing elements, and gives you no way to tell whether this has happened.insert
that you list involve an implicit type conversion, which may slow your code down.The major drawback is that this form used to require the key and value to be copyable, so it wouldn't work with e.g. a map with unique_ptr
values. That has been fixed in the standard, but the fix may not have reached your standard library implementation yet.
Second, you can use the emplace()
method:
function.emplace(0, 42);
This is more concise than any of the forms of insert()
, works fine with move-only types like unique_ptr
, and theoretically may be slightly more efficient (although a decent compiler should optimize away the difference). The only major drawback is that it may surprise your readers a little, since emplace
methods aren't usually used that way.
For non-servers this requires Remote Server Administration Tools for Windows __
You can set a property on the form to do this for you if you have a button on the form that closes the form already.
Set the CancelButton
property of the form to that button.
Gets or sets the button control that is clicked when the user presses the Esc key.
If you don't have a cancel button then you'll need to add a KeyDown
handler and check for the Esc key in that:
private void Form_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Escape)
{
this.Close();
}
}
You will also have to set the KeyPreview
property to true.
Gets or sets a value indicating whether the form will receive key events before the event is passed to the control that has focus.
However, as Gargo points out in his answer this will mean that pressing Esc to abort an edit on a control in the dialog will also have the effect of closing the dialog. To avoid that override the ProcessDialogKey
method as follows:
protected override bool ProcessDialogKey(Keys keyData)
{
if (Form.ModifierKeys == Keys.None && keyData == Keys.Escape)
{
this.Close();
return true;
}
return base.ProcessDialogKey(keyData);
}
What about something like this:
print [ord(char) - 96 for char in raw_input('Write Text: ').lower()]
ord
list comprehension
ASCII character codes
EDIT
Since you asked me to explain I will... though it has been explained pretty well in the comments already by [?].
Let's do this in more that one line to start.
input = raw_input('Write Text: ')
input = input.lower()
output = []
for character in input:
number = ord(character) - 96
output.append(number)
print output
This does the same thing, but is more readable. Make sure you can understand what is going on here before you try to understand my first answer. Everything here is pretty standard, simple Python. The one thing to note is the ord
function. ord stand for ordinal, and pretty much every high level language will have this type of function available. It gives you a mapping to the numerical representation of any character. The inverse function of ord is called chr.
chr(ord('x')) == 'x' # for any character, not just x.
If you test for yourself, the ordinal of a is 97 (the third link I posted above will show the complete ASCII character set.) Each lower case letter is in the range 97-122 (26 characters.) So, if you just subtract 96 from the ordinal of any lower case letter, you will get its position in the alphabet assuming you take 'a' == 1. So, ordinal of 'b' == 98, 'c' == 99, etc. When you subtract 96, 'b' == 2, 'c' == 3, etc.
The rest of the initial solution I posted is just some Python trickery you can learn called list comprehension. But, I wouldn't focus on that as much as I would focus on learning to solve the problem in any language, where ord is your friend. I hope this helps.
I had an instance where .gitignore

curl's --data
will by default send Content-Type: application/x-www-form-urlencoded
in the request header. However, when using Postman's raw
body mode, Postman sends Content-Type: text/plain
in the request header.
So to achieve the same thing as Postman, specify -H "Content-Type: text/plain"
for curl:
curl -X POST -H "Content-Type: text/plain" --data "this is raw data" http://78.41.xx.xx:7778/
Note that if you want to watch the full request sent by Postman, you can enable debugging for packed app. Check this link for all instructions. Then you can inspect the app (right-click in Postman) and view all requests sent from Postman in the network

The function mb_strlen()
is not enabled by default in PHP. Please read the manual for installation details:
I thought I would provide a much more robust example, also in typescript, but it would be easy to convert to pure javascript. This function will query parents using either the ID like so "#my-element" or the class ".my-class" and unlike some of these answers will handle multiple classes. I found I named some similarly and so the examples above were finding the wrong things.
function queryParentElement(el:HTMLElement | null, selector:string) {
let isIDSelector = selector.indexOf("#") === 0
if (selector.indexOf('.') === 0 || selector.indexOf('#') === 0) {
selector = selector.slice(1)
}
while (el) {
if (isIDSelector) {
if (el.id === selector) {
return el
}
}
else if (el.classList.contains(selector)) {
return el;
}
el = el.parentElement;
}
return null;
}
let elementByClassName = queryParentElement(someElement,".my-class")
let elementByID = queryParentElement(someElement,"#my-element")
I use PHP to find the URL and match the page name (without the extension of .php, also I can add multiple pages that all have the same word in common like contact, contactform, etc. All will have that class added) and add a class with PHP to change the color, etc.
For that you would have to save your pages with file extension .php
.
Here is a demo. Change your links and pages as required. The CSS class for all the links is .tab
and for the active link there is also another class of .currentpage
(as is the PHP function) so that is where you will overwrite your CSS rules.
You could name them whatever you like.
<?php # Using REQUEST_URI
$currentpage = $_SERVER['REQUEST_URI'];?>
<div class="nav">
<div class="tab
<?php
if(preg_match("/index/i", $currentpage)||($currentpage=="/"))
echo " currentpage";
?>"><a href="index.php">Home</a>
</div>
<div class="tab
<?php
if(preg_match("/services/i", $currentpage))
echo " currentpage";
?>"><a href="services.php">Services</a>

<?php
if(preg_match("/about/i", $currentpage))
echo " currentpage";
?>"><a href="about.php">About</a>
</div>
<div class="tab
<?php
if(preg_match("/contact/i", $currentpage))
echo " currentpage";
?>"><a href="contact.php">Contact</a>
</div>
</div> <!--nav-->
Hm.
You have to specify window you clicked in Mouse.GetPosition(IInputElement relativeTo)
Following code works well for me
protected override void OnMouseDown(MouseButtonEventArgs e)
{
base.OnMouseDown(e);
Point p = e.GetPosition(this);
}
I suspect that you need to refer to the window not from it own class but from other point of the application. In this case Application.Current.MainWindow
will help you.
Decimal representation of floating point numbers is kind of strange. If you have a number with 15 decimal places and convert that to a double
, then print it out with exactly 15 decimal places, you should get the same number. On the other hand, if you print out an arbitrary double
with 15 decimal places and the convert it back to a double
, you won't necessarily get the same value back—you need 17 decimal places for that. And neither 15 nor 17 decimal places are enough to accurately display the exact decimal equivalent of an arbitrary double
. In general, you need over 100 decimal places to do that precisely.
See the Wikipedia page for double-precision and this article on floating-point precision.
For my suggestion, please read the last section: “When to use SO_LINGER with timeout 0”.
Before we come to that a little lecture about:
TIME_WAIT
FIN
, ACK
and RST
The normal TCP termination sequence looks like this (simplified):
We have two peers: A and B
close()
FIN
to BFIN_WAIT_1
stateFIN
ACK
to ACLOSE_WAIT
stateACK
FIN_WAIT_2
stateclose()
FIN
to ALAST_ACK
stateFIN
ACK
to BTIME_WAIT
stateACK
CLOSED
state – i.e. is removed from the socket tablesSo the peer that initiates the termination – i.e. calls close()
first – will end up in the TIME_WAIT
state.
To understand why the TIME_WAIT
state is our friend, please read section 2.7 in "UNIX Network Programming" third edition by Stevens et al (page 43).
However, it can be a problem with lots of sockets in TIME_WAIT
state on a server as it could eventually prevent new connections from being accepted.
To work around this problem, I have seen many suggesting to set the SO_LINGER socket option with timeout 0 before calling close()
. However, this is a bad solution as it causes the TCP connection to be terminated with an error.
Instead, design your application protocol so the connection termination is always initiated from the client side. If the client always knows when it has read all remaining data it can initiate the termination sequence. As an example, a browser knows from the Content-Length
HTTP header when it has read all data and can initiate the close. (I know that in HTTP 1.1 it will keep it open for a while for a possible reuse, and then close it.)
If the server needs to close the connection, design the application protocol so the server asks the client to call close()
.
Again, according to "UNIX Network Programming" third edition page 202-203, setting SO_LINGER
with timeout 0 prior to calling close()
will cause the normal termination sequence not to be initiated.
Instead, the peer setting this option and calling close()
will send a RST
(connection reset) which indicates an error condition and this is how it will be perceived at the other end. You will typically see errors like "Connection reset by peer".
Therefore, in the normal situation it is a really bad idea to set SO_LINGER
with timeout 0 prior to calling close()
– from now on called abortive close – in a server application.
However, certain situation warrants doing so anyway:
CLOSE_WAIT
or ending up in the TIME_WAIT
state.TIME_WAIT
(when calling close()
from the server end) as this might prevent the server from getting available ports for new client connections after being restarted.CLOSE_WAIT
trying to deliver data to a stuck terminal port, but would properly reset the stuck port if it got an RST
to discard the pending data."I would recommend this long article which I believe gives a very good answer to your question.
Neither of these options is correct. You're trying to implement a synchronous interface asynchronously. Don't do that. The problem is that when DoOperation()
returns, the operation won't be complete yet. Worse, if an exception happens during the operation (which is very common with IO operations), the user won't have a chance to deal with that exception.
What you need to do is to modify the interface, so that it is asynchronous:
interface IIO
{
Task DoOperationAsync(); // note: no async here
}
class IOImplementation : IIO
{
public async Task DoOperationAsync()
{
// perform the operation here
}
}
This way, the user will see that the operation is async
and they will be able to await
it. This also pretty much forces the users of your code to switch to async
, but that's unavoidable.
Also, I assume using StartNew()
in your implementation is just an example, you shouldn't need that to implement asynchronous IO. (And new Task()
is even worse, that won't even work, because you don't Start()
the Task
.)
My code let the browser go back one page, and if that fails it loads a fallback url. It also detect hashtags changes.
When the back button wasn't available, the fallback url will be loaded after 500 ms, so the browser has time enough to load the previous page. Loading the fallback url right after window.history.go(-1);
would cause the browser to use the fallback url, because the js script didn't stop yet.
function historyBackWFallback(fallbackUrl) {
fallbackUrl = fallbackUrl || '/';
var prevPage = window.location.href;
window.history.go(-1);
setTimeout(function(){
if (window.location.href == prevPage) {
window.location.href = fallbackUrl;
}
}, 500);
}
In your .gradle
change MinSDK, for example:
build.gradle

minSdkVersion 9
minSdkVersion 14
etc.
Try this
String[] arr = list.toArray(new String[list.size()]);
AF_INET = Address Format, Internet = IP Addresses
PF_INET = Packet Format, Internet = IP, TCP/IP or UDP/IP
AF_INET is the address family that is used for the socket you're creating (in this case an Internet Protocol address). The Linux kernel, for example, supports 29 other address families such as UNIX sockets and IPX, and also communications with IRDA and Bluetooth (AF_IRDA and AF_BLUETOOTH, but it is doubtful you'll use these at such a low level).
For the most part sticking with AF_INET for socket programming over a network is the safest option.
Meaning, AF_INET refers to addresses from the internet, IP addresses specifically.
PF_INET refers to anything in the protocol, usually sockets/ports.
Sharing a personal case if it helps. It is that a virtual environment was previously arranged. Its path can be displayed by
echo $VIRTUAL_ENV
Make sure that the it is writable to the current user. If not, using
sudo ipython
would certainly clear off the warning message.
In anaconda, if $VIRTUAL_ENV is independently arranged, one can simply delete this folder or rename it, and then restart the shell. Anaconda will recover to its default setup.
Use the "has attribute" selector:
$('p[MyTag]')
Or to select one where that attribute has a specific value:
$('p[MyTag="Sara"]')
There are other selectors for "attribute value starts with", "attribute value contains", etc.

To find all tables containing a particular foreign key such as employee_id
SELECT DISTINCT TABLE_NAME
FROM INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME IN ('employee_id')
AND TABLE_SCHEMA='table_name';
As an extra thought, if is needed to pass the column name unquoted to the custom function, perhaps match.call()
could be useful as well in this case, as an alternative to deparse(substitute())
:
df <- data.frame(A = 1:10, B = 2:11)
fun <- function(x, column){
arg <- match.call()
max(x[[arg$column]])
}
fun(df, A)
#> [1] 10
fun(df, B)
#> [1] 11
If there is a typo in the column name, then would be safer to stop with an error:
fun <- function(x, column) max(x[[match.call()$column]])
fun(df, typo)
#> Warning in max(x[[match.call()$column]]): no non-missing arguments to max;
#> returning -Inf
#> [1] -Inf
# Stop with error in case of typo
fun <- function(x, column){
arg <- match.call()
if (is.null(x[[arg$column]])) stop("Wrong column name")
max(x[[arg$column]])
}
fun(df, typo)
#> Error in fun(df, typo): Wrong column name
fun(df, A)
#> [1] 10

I do not think I would use this approach since there is extra typing and complexity than just passing the quoted column name as pointed in the above answers, but well, is an approach.

Take a look at Count(*) vs Count(1) which may be the issue you were described.
The Excel number for a modern date is most easily calculated as the number of days since 12/30/1899 on the Gregorian calendar.
Excel treats the mythical date 01/00/1900 (i.e., 12/31/1899) as corresponding to 0, and incorrectly treats year 1900 as a leap year. So for dates before 03/01/1900, the Excel number is effectively the number of days after 12/31/1899.
However, Excel will not format any number below 0 (-1 gives you ##########) and so this only matters for "01/00/1900" to 02/28/1900, making it easier to just use the 12/30/1899 date as a base.
A complete function in DB2 SQL that accounts for the leap year 1900 error:
SELECT
DAYS(INPUT_DATE)
- DAYS(DATE('1899-12-30'))
- CASE
WHEN INPUT_DATE < DATE('1900-03-01')
THEN 1
ELSE 0
END
You get this message in the logs, because you do something that is not allowed in the current state of your MediaPlayer instance.
Therefore you should always register an error handler to catch those things (as @tidbeck suggested).
At first, I advice you to take a look at the documentation for the MediaPlayer
class and get an understanding of what that with states means. See: http://developer.android.com/reference/android/media/MediaPlayer.html#StateDiagram
Your mistake here could well be one of the common ones, the others wrote here, but in general, I would take a look at the documentation of what methods are valid to call in what state: http://developer.android.com/reference/android/media/MediaPlayer.html#Valid_and_Invalid_States
In my example it was the method mediaPlayer.CurrentPosition
, that I called while the media player was in a state, where it was not allowed to call this property.
I encountered with this issue spending couple of hours, however solved it in different ways. You can see, I have just created an assets folder outside application folder. Finally I linked my style sheet in the page header section. Folder structure are below images.
Before action this you should include url helper file either in your controller class method/__constructor files or by in autoload.php file. Also change $config['base_url'] = 'http://yoursiteurl';
in the following file application/config/config.php
If you include it in controller class method/__constructor then it look like
public function __construct()
{
$this->load->helper('url');
}
or If you load in autoload file then it would looks like
$autoload['helper'] = array('url');
Finally, add your stylesheet file. You can link a style sheet by different ways, include it in your inside section
-><link rel="stylesheet" href="<?php echo base_url();?>assets/css/style.css" type="text/css" />
-> or
<?php
$main = array(
'href' => 'assets/css/style.css',
'rel' => 'stylesheet',
'type' => 'text/css',
'title' => 'main stylesheet',
'media' => 'all',
'index_page' => true
);
echo link_tag($main); ?>
-> or
finally I get more reliable code cleaner concept. Just create a config file, named styles.php in you application/config/styles.php folder. Then add some links in styles.php file looks like below
<?php
$config['style'] = array(
'main' => array(
'href' => 'assets/css/style.css',
'rel' => 'stylesheet',
'type' => 'text/css',
'title' => 'main stylesheet',
'media' => 'all',
'index_page' => true
)
);
?>
call/add this config to your controller class method looks like below
$this->config->load('styles');
$data['style'] = $this->config->config['style'];
Pass this data in your header template looks like below.
$this->load->view('templates/header', $data);
And finally add or link your css file looks like below.
<?php echo link_tag($style['main']); ?>

You need to be aware about how AngularJS works in order to understand it.
First and foremost, AngularJS defines a concept of a so-called digest cycle. This cycle can be considered as a loop, during which AngularJS checks if there are any changes to all the variables watched by all the $scope
s. So if you have $scope.myVar
defined in your controller and this variable was marked for being watched, then you are implicitly telling AngularJS to monitor the changes on myVar
in each iteration of the loop.
A natural follow-up question would be: Is everything attached to $scope
being watched? Fortunately, no. If you would watch for changes to every object in your $scope
, then quickly a digest loop would take ages to evaluate and you would quickly run into performance issues. That is why the AngularJS team gave us two ways of declaring some $scope
variable as being watched (read below).
There are two ways of declaring a $scope
variable as being watched.
<span>{{myVar}}</span>
$watch
serviceAd 1)
This is the most common scenario and I'm sure you've seen it before, but you didn't know that this has created a watch in the background. Yes, it had! Using AngularJS directives (such as ng-repeat
) can also create implicit watches.
Ad 2)
This is how you create your own watches. $watch
service helps you to run some code when some value attached to the $scope
has changed. It is rarely used, but sometimes is helpful. For instance, if you want to run some code each time 'myVar' changes, you could do the following:
function MyController($scope) {
$scope.myVar = 1;
$scope.$watch('myVar', function() {
alert('hey, myVar has changed!');
});
$scope.buttonClicked = function() {
$scope.myVar = 2; // This will trigger $watch expression to kick in
};
}
You can think of the $apply
function as of an integration mechanism. You see, each time you change some watched variable attached to the $scope
object directly, AngularJS will know that the change has happened. This is because AngularJS already knew to monitor those changes. So if it happens in code managed by the framework, the digest cycle will carry on.
However, sometimes you want to change some value outside of the AngularJS world and see the changes propagate normally.
Consider this - you have a $scope.myVar
value which will be modified within a jQuery's $.ajax()
handler. This will happen at some point in future. AngularJS can't wait for this to happen, since it hasn't been instructed to wait on jQuery.
To tackle this, $apply
has been introduced. It lets you start the digestion cycle explicitly. However, you should only use this to migrate some data to AngularJS (integration with other frameworks), but never use this method combined with regular AngularJS code, as AngularJS will throw an error then.
Well, you should really follow the tutorial again, now that you know all this. The digest cycle will make sure that the UI and the JavaScript code stay synchronised, by evaluating every watcher attached to all $scope
s as long as nothing changes. If no more changes happen in the digest loop, then it's considered to be finished.
You can attach objects to the $scope
object either explicitly in the Controller, or by declaring them in {{expression}}
form directly in the view.
I hope that helps to clarify some basic knowledge about all this.

If you are using styled-components
, you could do something like this:
import React, { Component } from 'react';
import { Link } from 'react-router-dom';
import styled from 'styled-components';
const StyledLink = styled(Link)`
text-decoration: none;
&:focus, &:hover, &:visited, &:link, &:active {
text-decoration: none;
}
`;
export default (props) => <StyledLink {...props} />;
This can be the solution:
git fetch
git checkout origin/master -- FolderPathName/fileName

The GuidToBinary routine posted by KCD should be tweaked to account for the bit layout of the timestamp in the GUID string. If the string represents a version 1 UUID, like those returned by the uuid() mysql routine, then the time components are embedded in letters 1-G, excluding the D.
12345678-9ABC-DEFG-HIJK-LMNOPQRSTUVW
12345678 = least significant 4 bytes of the timestamp in big endian order
9ABC = middle 2 timestamp bytes in big endian
D = 1 to signify a version 1 UUID
EFG = most significant 12 bits of the timestamp in big endian
When you convert to binary, the best order for indexing would be: EFG9ABC12345678D + the rest.
You don't want to swap 12345678 to 78563412 because big endian already yields the best binary index byte order. However, you do want the most significant bytes moved in front of the lower bytes. Hence, EFG go first, followed by the middle bits and lower bits. Generate a dozen or so UUIDs with uuid() over the course of a minute and you should see how this order yields the correct rank.
select uuid(), 0
union
select uuid(), sleep(.001)
union
select uuid(), sleep(.010)
union
select uuid(), sleep(.100)
union
select uuid(), sleep(1)
union
select uuid(), sleep(10)
union
select uuid(), 0;

The first two UUIDs were generated closest in time. They only vary in the last 3 nibbles of the first block. These are the least significant bits of the timestamp, which means we want to push them to the right when we convert this to an indexable byte array. As a counter example, the last ID is the most current, but the KCD's swapping algorithm would put it before the 3rd ID (3e before dc, last bytes from the first block).
The correct order for indexing would be:
1e497556eec5eb6...
1e497556eec5f10...
1e497556eec8ddc...
1e497556eee30d0...
1e497556efda038...
1e497556f9641bf...
1e49755758c3e3e...
See this article for supporting information: http://mysql.rjweb.org/doc.php/uuid
*** note that I don't split the version nibble from the high 12 bits of the timestamp. This is the D nibble from your example. I just throw it in front. So my binary sequence ends up being DEFG9ABC and so on. This implies that all my indexed UUIDs start with the same nibble. The article does the same thing.
SQL Server uses Julian dates so your 30 means "30 calendar days". getdate() - 0.02083 means "30 minutes ago".
You need to use the command echo $PATH
to display the PATH variable or you can just execute set
or env
to display all of your environment variables.
By typing $PATH
you tried to run your PATH variable contents as a command name.
Bash displayed the contents of your path any way. Based on your output the following directories will be searched in the following order:
/usr/local/share/npm/bin
/Library/Frameworks/Python.framework/Versions/2.7/bin
/usr/local/bin
/usr/local/sbin
~/bin
/Library/Frameworks/Python.framework/Versions/Current/bin
/usr/bin
/bin
/usr/sbin
/sbin
/usr/local/bin
/opt/X11/bin
/usr/local/git/bin
To me this list appears to be complete.
It gets a little bit more complicated if you want to add the background to a specific modal. One way of solving that is to add and call something like this function instead of showing the modal directly:
function showModal(selector) {
$(selector).modal('show');
$('.modal-backdrop').addClass('background-backdrop');
}
Any css can then be applied to the background-backdrop
class.
You can get top and left without traversing DOM like this:
function getCoords(elem) { // crossbrowser version
var box = elem.getBoundingClientRect();
var body = document.body;
var docEl = document.documentElement;
var scrollTop = window.pageYOffset || docEl.scrollTop || body.scrollTop;
var scrollLeft = window.pageXOffset || docEl.scrollLeft || body.scrollLeft;
var clientTop = docEl.clientTop || body.clientTop || 0;
var clientLeft = docEl.clientLeft || body.clientLeft || 0;
var top = box.top + scrollTop - clientTop;
var left = box.left + scrollLeft - clientLeft;
return { top: Math.round(top), left: Math.round(left) };
}
When I was recently looking for an R function returning indexes of top N max/min numbers in a given vector, I was surprised there is no such a function.
And this is something very similar.
The brute force solution using base::order function seems to be the easiest one.
topMaxUsingFullSort <- function(x, N) {
sort(x, decreasing = TRUE)[1:min(N, length(x))]
}
But it is not the fastest one in case your N value is relatively small compared to length of the vector x.
On the other side if the N is really small, you can use base::whichMax function iteratively and in each iteration you can replace found value by -Inf
# the input vector 'x' must not contain -Inf value
topMaxUsingWhichMax <- function(x, N) {
vals <- c()
for(i in 1:min(N, length(x))) {
idx <- which.max(x)
vals <- c(vals, x[idx]) # copy-on-modify (this is not an issue because idxs is relative small vector)
x[idx] <- -Inf # copy-on-modify (this is the issue because data vector could be huge)
}
vals
}
I believe you see the problem - the copy-on-modify nature of R. So this will perform better for very very very small N (1,2,3) but it will rapidly slow down for larger N values. And you are iterating over all elements in vector x N times.
I think the best solution in clean R is to use partial base::sort.
topMaxUsingPartialSort <- function(x, N) {
N <- min(N, length(x))
x[x >= -sort(-x, partial=N)[N]][1:N]
}
Then you can select the last (Nth) item from the result of functions defiend above.
Note: functions defined above are just examples - if you want to use them, you have to check/sanity inputs (eg. N > length(x)).
I wrote a small article about something very similar (get indexes of top N max/min values of a vector) at http://palusga.cz/?p=18 - you can find here some benchmarks of similar functions I defined above.
You can also use the PostAsJsonAsync() method available in HttpClient()
var requestObj= JsonConvert.SerializeObject(obj);_x000D_
HttpResponseMessage response = await client.PostAsJsonAsync($"endpoint",requestObj).ConfigureAwait(false);
_x000D_
In our case, everything LOOKED ok, but it took most of the day to figure this out:
TLDR: Check your certificate paths to make sure the root certificate is correct. In the case of COMODO certificates, it should say "USERTrust" and be issued by "AddTrust External CA Root". NOT "COMODO" issued by "COMODO RSA Certification Authority".
From the CloudFront docs: http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/SecureConnections.html
If the origin server returns an invalid certificate or a self-signed certificate, or if the origin server returns the certificate chain in the wrong order, CloudFront drops the TCP connection, returns HTTP error code 502, and sets the X-Cache header to Error from cloudfront.
We had the right ciphers enabled as per: http://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/RequestAndResponseBehaviorCustomOrigin.html#RequestCustomEncryption
Our certificate was valid according to Google, Firefox and ssl-checker: https://www.sslshopper.com/ssl-checker.html
However the last certificate in the ssl checker chain was "COMODO RSA Domain Validation Secure Server CA", issued by "COMODO RSA Certification Authority"
It seems that CloudFront does not hold the certificate for "COMODO RSA Certification Authority" and as such thinks the certificate provided by the origin server is self signed.
This was working for a long time before apparently suddenly stopping. What happened was I had just updated our certificates for the year, but during the import, something was changed in the certificate path for all the previous certificates. They all started referencing "COMODO RSA Certification Authority" whereas before the chain was longer and the root was "AddTrust External CA Root".
Because of this, switching back to the older cert did not fix the cloudfront issue.
I had to delete the extra certificate named "COMODO RSA Certification Authority", the one that did not reference AddTrust. After doing this, all my website certificates' paths updated to point back to AddTrust/USERTrust again. Note can also open up the bad root certificate from the path, click "Details" -> "Edit Properties" and then disable it that way. This updated the path immediately. You may also need to delete multiple copies of the certificate, found under "Personal" and "Trusted Root Certificate Authorities"
Finally I had to re select the certificate in IIS to get it to serve the new certificate chain.
After all this, ssl-checker started displaying a third certificate in the chain, which pointed back to "AddTrust External CA Root"
Finally, CloudFront accepted the origin server's certificate and the provided chain as being trusted. Our CDN started working correctly again!
To prevent this happening in the future, we will need to export our newly generated certificates from a machine with the correct certificate chain, i.e. distrust or delete the certificate "COMODO RSA Certification Authroity" issued by "COMODO RSA Certification Authroity" (expiring in 2038). This only seems to affect windows machines, where this certificate is installed by default.
The following might help you:
ini_set('max_execution_time', 100000);
And in your mysql - max_allowed_packet=100M
in some cases where queries are too long sql also produce and error "MySQL server has gone away";
Change the values to whatever you need.
There is one more way to achieve it:-
Private Sub UserForm_Initialize()
Dim list As Object
Set list = UserForm1.Controls.Add("Forms.ListBox.1", "hello", True)
With list
.Top = 30
.Left = 30
.Width = 200
.Height = 340
.ColumnHeads = True
.ColumnCount = 2
.ColumnWidths = "100;100"
.MultiSelect = fmMultiSelectExtended
.RowSource = "Sheet1!C4:D25"
End With End Sub
Here, I am using the range C4:D25 as source of data for the columns. It will result in both the columns populated with values.
The properties are self explanatory. You can explore other options by drawing ListBox in UserForm and using "Properties Window (F4)" to play with the option values.
Given your URL:
http://locahost:8000/example?a=10
The best way that I have found to get the value for 'a' and display it on the page is to use the following:
{{ request()->get('a') }}
However, if you want to use it within an if statement, you could use:
@if( request()->get('a') )
<script>console.log('hello')</script>
@endif
Hope that helps someone! :)
I’m pretty sure you don’t add the mime type as a JPEG on file downloads:
header('Content-Type: image/png');
These headers have never failed me:
$quoted = sprintf('"%s"', addcslashes(basename($file), '"\\'));
$size = filesize($file);
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename=' . $quoted);
header('Content-Transfer-Encoding: binary');
header('Connection: Keep-Alive');
header('Expires: 0');
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
header('Pragma: public');
header('Content-Length: ' . $size);
Assuming you do as David Zaslavsky suggests, so that the first argument simply is the program to run (no option-parsing required), you're dealing with the question of how to pass arguments 2 and on to your external program. Here's a convenient way:
#!/bin/bash
ext_program="$1"
shift
"$ext_program" "$@"
The shift
will remove the first argument, renaming the rest ($2
becomes $1, and so on).
$@` refers to the arguments, as an array of words (it must be quoted!).
If you must have your --file
syntax (for example, if there's a default program to run, so the user doesn't necessarily have to supply one), just replace ext_program="$1"
with whatever parsing of $1
you need to do, perhaps using getopt or getopts.
If you want to roll your own, for just the one specific case, you could do something like this:
if [ "$#" -gt 0 -a "${1:0:6}" == "--file" ]; then
ext_program="${1:7}"
else
ext_program="default program"
fi
You can use:
set content=
for /f "delims=" %%i in ('type text.txt') do set content=!content! %%i
var distinctItems = items.Distinct();
To match on only some of the properties, create a custom equality comparer, e.g.:
class DistinctItemComparer : IEqualityComparer<Item> {
public bool Equals(Item x, Item y) {
return x.Id == y.Id &&
x.Name == y.Name &&
x.Code == y.Code &&
x.Price == y.Price;
}
public int GetHashCode(Item obj) {
return obj.Id.GetHashCode() ^
obj.Name.GetHashCode() ^
obj.Code.GetHashCode() ^
obj.Price.GetHashCode();
}
}
Then use it like this:
var distinctItems = items.Distinct(new DistinctItemComparer());
Easy way out is to use a condition like this ( use desired date > GETDATE()-1)
your sql statement "date specific" > GETDATE()-1
You need a new version of notepad++. Looks like old versions don't support |
.
Note: egrep "CAT|TOWN"
will search for lines containing CATOWN. (CAT)|(TOWN)
is the proper or extension (matching 1,3,4). Strangely you wrote and which is btw (CAT.*TOWN)|(TOWN.*CAT)
Agreed with Yuri Tkachenko's answer.
I wanna point this out.
It's a pretty specific scenario. BUT it happens.
When you copy a gif before its loaded fully in some site like google images. it just gives the preview image address of that gif. Which is clearly not a gif.
So, make sure it ends with .gif extension
To do it in a simpler way, consider below:
JsonObject jsonObject = (new JsonParser()).parse(json).getAsJsonObject();
I would have thought that something like this would be much better, since you're adding a variable, so why not restrict access and make it cleaner? Your getter/setters should do what they say on the tin.
public abstract class ExternalScript extends Script {
private String source;
public void setSource(String file) {
source = file;
}
public String getSource() {
return source;
}
}
Bringing this back to the question, do you ever bother looking at where the getter/setter code is when reading it? If they all do getting and setting then you don't need to worry about what the function 'does' when reading the code. There are a few other reasons to think about too:
Always think whether your class is really a different thing or not, and that should help decide whether you need anything more.
The example on the Python docs is quite straightforward:
groups = []
uniquekeys = []
for k, g in groupby(data, keyfunc):
groups.append(list(g)) # Store group iterator as a list
uniquekeys.append(k)
So in your case, data is a list of nodes, keyfunc
is where the logic of your criteria function goes and then groupby()
groups the data.
You must be careful to sort the data by the criteria before you call groupby
or it won't work. groupby
method actually just iterates through a list and whenever the key changes it creates a new group.
I took the wiki answer and I translated it into typescript static class, for people that come from for example angular.

These examples seem a bit inefficient. Try this if you want to act upon the value:
<input id="cta" type="email" placeholder="Enter Email...">
<button onclick="return joinMailingList()">Join</button>
<script>
const joinMailingList = () => {
const email = document.querySelector('#cta').value
console.log(email)
}
</script>
You will encounter issue if you use this
keyword with fat arrow (=>
). If you need to do that, go old school:
<script>
function joinMailingList() {
const email = document.querySelector('#cta').value
console.log(email)
}
</script>
If you are working with password inputs, you should use type="password"
so it will display ****** while the user is typing, and it is also more semantic.
To check if any module in a project is 'old':
npm outdated
'outdated' will check every module defined in package.json
and see if there is a newer version in the NPM registry.
For example, say xml2js 0.2.6
(located in node_modules
in the current project) is outdated because a newer version exists (0.2.7). You would see:
[email protected] node_modules/xml2js current=0.2.6
To update all dependencies, if you are confident this is desirable:
npm update
Or, to update a single dependency such as xml2js
:
npm update xml2js
ElementFormDefault has nothing to do with namespace of the types in the schema, it's about the namespaces of the elements in XML documents which comply with the schema.
Here's the relevent section of the spec:
Element Declaration Schema Component Property {target namespace} Representation If form is present and its ·actual value· is qualified, or if form is absent and the ·actual value· of elementFormDefault on the <schema> ancestor is qualified, then the ·actual value· of the targetNamespace [attribute] of the parent <schema> element information item, or ·absent· if there is none, otherwise ·absent·.
What that means is that the targetNamespace you've declared at the top of the schema only applies to elements in the schema compliant XML document if either elementFormDefault is "qualified" or the element is declared explicitly in the schema as having form="qualified".
For example: If elementFormDefault is unqualified -
<element name="name" type="string" form="qualified"></element>
<element name="page" type="target:TypePage"></element>
will expect "name" elements to be in the targetNamespace and "page" elements to be in the null namespace.
To save you having to put form="qualified" on every element declaration, stating elementFormDefault="qualified" means that the targetNamespace applies to each element unless overridden by putting form="unqualified" on the element declaration.
to pass the event
object:
<p id="p" onclick="doSomething(event)">
to get the clicked child element
(should be used with event
parameter:
function doSomething(e) {
e = e || window.event;
var target = e.target || e.srcElement;
console.log(target);
}
to pass the element
itself (DOMElement):
<p id="p" onclick="doThing(this)">
see live example on jsFiddle.
You can specify the name of the event
as above, but alternatively your handler can access the event
parameter as described here: "When the event handler is specified as an HTML attribute, the specified code is wrapped into a function with the following parameters". There's much more additional documentation at the link.
public class Factorial2 {
public static long factorial(long x) {
if (x < 0)
throw new IllegalArgumentException("x must be >= 0");
if (x <= 1)
return 1; // Stop recursing here
else
return x * factorial(x-1); // Recurse by calling ourselves
}
}
You just need to use the Gradle Application plugin:
apply plugin:'application'
mainClassName = "org.gradle.sample.Main"
And then simply gradle run
.
As Teresa points out, you can also configure mainClassName
as a system property and run with a command line argument.
Simplest of all would be.
Create xml layout file for dialog . Add whatever view you want like EditText , ListView , Spinner etc.
Inflate this view and set this to AlertDialog
Lets start with Layout file first.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:orientation="vertical">
<EditText
android:id="@+id/etComments"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="top"
android:hint="Enter comments(Optional)"
android:inputType="textMultiLine"
android:lines="8"
android:maxLines="3"
android:minLines="6"
android:scrollbars="vertical" />
</LinearLayout>
final View view = layoutInflater.inflate(R.layout.xml_file_created_above, null);
AlertDialog alertDialog = new AlertDialog.Builder(ct).create();
alertDialog.setTitle("Your Title Here");
alertDialog.setIcon("Icon id here");
alertDialog.setCancelable(false);
Constant.alertDialog.setMessage("Your Message Here");
final EditText etComments = (EditText) view.findViewById(R.id.etComments);
alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
alertDialog.setButton(AlertDialog.BUTTON_NEGATIVE, "Cancel", new OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
alertDialog.dismiss()
}
});
alertDialog.setView(view);
alertDialog.show();
Grouped Array of Object in typescript with this:
groupBy (list: any[], key: string): Map<string, Array<any>> {
let map = new Map();
list.map(val=> {
if(!map.has(val[key])){
map.set(val[key],list.filter(data => data[key] == val[key]));
}
});
return map;
});
You can check Wikipedia. But mainly when more actions or resources are used. Like if you are familiar with .NET there you can have value types and reference types. Reference types have memory overhead as they require more memory than value types.
For an uglier version of unshift
use splice
:
TheArray.splice(0, 0, TheNewObject);
just using this:
select {
text-align-last: center;
padding-right: 29px;
}
From the docs
To whitelist an entire hash of parameters, the permit! method can be used
params.require(:log_entry).permit!
Nested attributes are in the form of a hash. In my app, I have a Question.rb model accept nested attributes for an Answer.rb model (where the user creates answer choices for a question he creates). In the questions_controller, I do this
def question_params
params.require(:question).permit!
end
Everything in the question hash is permitted, including the nested answer attributes. This also works if the nested attributes are in the form of an array.
Having said that, I wonder if there's a security concern with this approach because it basically permits anything that's inside the hash without specifying exactly what it is, which seems contrary to the purpose of strong parameters.
sudo apt-get install nodejs
does not work for me. In order to get it to work, I have to do the following:
sudo apt-get install python-software-properties
sudo add-apt-repository ppa:chris-lea/node.js
sudo apt-get update
sudo apt-get install nodejs
Hope this will help someone having the same problem as me.
You could also use function exposed by the axes object of the scatter plot
scatter = plt.scatter(x, y)
ax = scatter.axes
ax.invert_xaxis()
ax.invert_yaxis()
You can choose:
if [[ $? -ne 0 ]]; then # -ne: not equal
if ! [[ $? -eq 0 ]]; then # -eq: equal
if [[ ! $? -eq 0 ]]; then
!
inverts the return of the following expression, respectively.
if(document.getElementById("question").value == "")
{
alert("empty")
}
Extending Udi's answer, this only checks on form submission, not on every input change.
$(document).ready( function () {
var form_data = $('#myform').serialize();
$('#myform').submit(function () {
if ( form_data == $(this).serialize() ) {
alert('no change');
} else {
alert('change');
}
});
});
1-firstly, drop the foreign key constraint after that drop the tables.
2-you can drop all foreign key via executing the following query:
DECLARE @SQL varchar(4000)=''
SELECT @SQL =
@SQL + 'ALTER TABLE ' + s.name+'.'+t.name + ' DROP CONSTRAINT [' + RTRIM(f.name) +'];' + CHAR(13)
FROM sys.Tables t
INNER JOIN sys.foreign_keys f ON f.parent_object_id = t.object_id
INNER JOIN sys.schemas s ON s.schema_id = f.schema_id
--EXEC (@SQL)
PRINT @SQL
if you execute the printed results @SQL, the foreign keys will be dropped.
There is no keyboard shortcut for restoring the perspective directly AFAIK. To open the Window menu (where Reset Perspective resides), try Alt-W. If that does not work, I guess your Eclipse has hung for some reason. Another shortcut you might want to try is F10 (should open the main menu).
Here is an example that should give you some idea..
=IIF(First(Fields!Gender.Value,"vw_BrgyClearanceNew")="Female" and
(First(Fields!CivilStatus.Value,"vw_BrgyClearanceNew")="Married"),false,true)
I think you have to identify the datasource name or the table name where your data is coming from.
I know the user asked this for Linux, but I had this issue in Windows (10 64bits) and found little information, so this is how I solved it:
In case LIBAV does not help, try with FFMPEG, copying the contents of the "bin" folder to where "youtube-dl.exe" is. That did not help me, but others said it did, so it may worth a try.
Hope this helps someone having the issue in Windows.
I realise this is an old post, but in case it helps, you can apply this CSS to have IE11 draw a dotted outline for the focus indication of a <select>
element so that it resembles Firefox's focus indication:
select:focus::-ms-value {
background: transparent;
color: inherit;
outline-style: dotted;
outline-width: thin;
}
You want Reflection
Type t = typeof(Car);
PropertyInfo prop = t.GetProperty("Make");
if(null != prop)
return prop.GetValue(this, null);
Use subquery
SELECT * FROM RES_DATA inner join (SELECT [CUSTOMER ID], sum([TOTAL AMOUNT]) FROM INV_DATA group by [CUSTOMER ID]) T on RES_DATA.[CUSTOMER ID] = t.[CUSTOMER ID]
This is the NPM known Issue for windows that NPM is pretty much unusable under Windows. This is of course related to the path size limitations.
https://github.com/npm/npm/issues/5641
My main concern here is that there are no mention of these issues when installing node or npm via the website. Not being able to install prime packages makes npm fundamentally unusable for windows.
just use a label tag, that way you can hide the input, and make it work through its related label https://developer.mozilla.org/fr/docs/Web/HTML/Element/Label
in visual studio for vb.net, go to the project properties, click Add Resource > Existing File, select your Icon.
in your code:
Me.Icon = My.Resources.IconResourceName
An alternative solution is to use a wrapper for the String
, for instances this:
public class StringResponse {
private String response;
public StringResponse(String response) {
this.response = response;
}
public String getResponse() {
return response;
}
}
Then return this in your controller's methods:
ResponseEntity<StringResponse>
For adding compression to the resulting zip file, check out this link.
You need to change:
zip = zipfile.ZipFile('Python.zip', 'w')
to
zip = zipfile.ZipFile('Python.zip', 'w', zipfile.ZIP_DEFLATED)
You can't, and you shouldn't.
Every other approach / alternative will only cause really bad user engagement.
That's my opinion.
You can put your test specific properties into src/test/resources/config/application.properties
.
The properties defined in this file will override those defined in src/main/resources/application.properties
during testing.
For more information on why this works have a look at Spring Boots docs.
jQuery v1.11.3
There is a lot of good information in the answers provided. But, recently I spent a lot of time trying to actually tie everything together into a working solution for the accomplishing two things:
Besides this post and Detecting touch screen devices with Javascript, I found this post by Patrick Lauke extremely helpful: https://hacks.mozilla.org/2013/04/detecting-touch-its-the-why-not-the-how/
Here is the code...
$(document).ready(function() {
//The page is "ready" and the document can be manipulated.
if (('ontouchstart' in window) || (navigator.maxTouchPoints > 0) || (navigator.msMaxTouchPoints > 0))
{
//If the device is a touch capable device, then...
$(document).on("touchstart", "a", function() {
//Do something on tap.
});
}
else
{
null;
}
});
Important! The *.on( events [, selector ] [, data ], handler )
method needs to have a selector, usually an element, that can handle the "touchstart" event, or any other like event associated with touches. In this case, it is the hyperlink element "a".
Now, you don't need to handle the regular mouse clicking in JavaScript, because you can use CSS to handle these events using selectors for the hyperlink "a" element like so:
/* unvisited link */
a:link
{
}
/* visited link */
a:visited
{
}
/* mouse over link */
a:hover
{
}
/* selected link */
a:active
{
}
Note: There are other selectors as well...

If you are already using SOLR, remain stick to it. If you are starting up, go for Elastic search.
Maximum major issues have been fixed in SOLR and it is quite mature.
I don't like the accepted answer or @fivetwentysix's comment regarding how to solve this. It gets at one method for doing this, but doesn't give the full solution to using toArray. You need to use toArray and give it an argument that's an array of the correct type and size so that you don't end up with an Object array. While an object array will work, I don't think it's best practice in a strongly typed language.
String[] array = arrayList.toArray(new String[arrayList.size()]);
JComboBox comboBox = new JComboBox(array);
Alternatively, you can also maintain strong typing by just using a for loop.
String[] array = new String[arrayList.size()];
for(int i = 0; i < array.length; i++) {
array[i] = arrayList.get(i);
}
JComboBox comboBox = new JComboBox(array);
alternative commands that does same job

It's called a Favicon, have a read.
<link rel="shortcut icon" href="http://www.example.com/myicon.ico"/>
You can use this neat tool to generate cross-browser compatible Favicons.
That's one of the reasons why you need to quote your variables:
echo "${str:$i:1}"
Otherwise, bash expands the variable and in this case does globbing before printing out. It is also better to quote the parameter to the script (in case you have a matching filename):
sh lash_ch.sh 'abcde*'
Also see the order of expansions in the bash reference manual. Variables are expanded before the filename expansion.
To get the last character you should just use -1
as the index since the negative indices count from the end of the string:
echo "${str: -1}"
The space after the colon (:
) is REQUIRED.
This approach will not work without the space.
If you don't want a timeout happening for some purpose:
<session-config>
<session-timeout>0</session-timeout>
</session-config>
Should result in no timeout at all -> infinite

Try HostingEnvironment.MapPath
, which is static
.
See this SO question for confirmation that HostingEnvironment.MapPath
returns the same value as Server.MapPath
: What is the difference between Server.MapPath and HostingEnvironment.MapPath?
You can use something like this
[HttpPost]
public async Task<HttpResponseMessage> AddFile()
{
if (!Request.Content.IsMimeMultipartContent())
{
this.Request.CreateResponse(HttpStatusCode.UnsupportedMediaType);
}
string root = HttpContext.Current.Server.MapPath("~/temp/uploads");
var provider = new MultipartFormDataStreamProvider(root);
var result = await Request.Content.ReadAsMultipartAsync(provider);
foreach (var key in provider.FormData.AllKeys)
{
foreach (var val in provider.FormData.GetValues(key))
{
if (key == "companyName")
{
var companyName = val;
}
}
}
// On upload, files are given a generic name like "BodyPart_26d6abe1-3ae1-416a-9429-b35f15e6e5d5"
// so this is how you can get the original file name
var originalFileName = GetDeserializedFileName(result.FileData.First());
var uploadedFileInfo = new FileInfo(result.FileData.First().LocalFileName);
string path = result.FileData.First().LocalFileName;
//Do whatever you want to do with your file here
return this.Request.CreateResponse(HttpStatusCode.OK, originalFileName );
}
private string GetDeserializedFileName(MultipartFileData fileData)
{
var fileName = GetFileName(fileData);
return JsonConvert.DeserializeObject(fileName).ToString();
}
public string GetFileName(MultipartFileData fileData)
{
return fileData.Headers.ContentDisposition.FileName;
}
If you want to unit test code then you need to isolate your code you want to test (in this case your service) from external resources (e.g. databases). You could probably do this with some sort of in-memory EF provider, however a much more common way is to abstract away your EF implementation e.g. with some sort of repository pattern. Without this isolation any tests you write will be integration tests, not unit tests.
As for testing EF code - I write automated integration tests for my repositories that write various rows to the database during their initialization, and then call my repository implementations to make sure that they behave as expected (e.g. making sure that results are filtered correctly, or that they are sorted in the correct order).
These are integration tests not unit tests, as the tests rely on having a database connection present, and that the target database already has the latest up-to-date schema installed.
Do one of the two jQuery serializers inside your form submit to get all inputs having a submitted value.
var criteria = $(this).find('input,select').filter(function () {
return ((!!this.value) && (!!this.name));
}).serializeArray();
var formData = JSON.stringify(criteria);
serializeArray() will produce an array of names and values
0: {name: "OwnLast", value: "Bird"}
1: {name: "OwnFirst", value: "Bob"}
2: {name: "OutBldg[]", value: "PDG"}
3: {name: "OutBldg[]", value: "PDA"}
var criteria = $(this).find('input,select').filter(function () {
return ((!!this.value) && (!!this.name));
}).serialize();
serialize() creates a text string in standard URL-encoded notation
"OwnLast=Bird&OwnFirst=Bob&OutBldg%5B%5D=PDG&OutBldg%5B%5D=PDA"
In order to sync
multiple models along with custom pivot data, you need this:
$user->roles()->sync([
1 => ['expires' => true],
2 => ['expires' => false],
...
]);
Ie.
sync([
related_id => ['pivot_field' => value],
...
]);
edit
Answering the comment:
$speakers = (array) Input::get('speakers'); // related ids
$pivotData = array_fill(0, count($speakers), ['is_speaker' => true]);
$syncData = array_combine($speakers, $pivotData);
$user->roles()->sync($syncData);
Yup, check out getImageData(). Here's an example of breaking CAPTCHA with JavaScript using canvas:
You can only use await
in an async
method, and Main
cannot be async
.
You'll have to use your own async
-compatible context, call Wait
on the returned Task
in the Main
method, or just ignore the returned Task
and just block on the call to Read
. Note that Wait
will wrap any exceptions in an AggregateException
.
If you want a good intro, see my async
/await
intro post.
Hold shift and right click on SQL Server Mangement studion icon. You can Run as other windows account user.
Once you have obtained the context in your onTap() you can also do:
Intent myIntent = new Intent(mContext, theNewActivity.class);
mContext.startActivity(myIntent);
My understanding is that arrays are stored more efficiently (i.e. as contiguous blocks of memory vs. pointers to Python objects), but I am not aware of any performance benefit. Additionally, with arrays you must store primitives of the same type, whereas lists can store anything.
You may work with Integer instead of int, Double instead of double, etc. (such classes exists for all primitive types).
Then you may use the operator instanceof, like if(var instanceof Integer){...}
I have made a dynamic function takes the objects Array, Key and value and returns the same array after removing the desired object:
function removeFunction (myObjects,prop,valu)
{
return myObjects.filter(function (val) {
return val[prop] !== valu;
});
}
Full Example: DEMO
var obj = {
"results": [
{
"id": "460",
"name": "Widget 1",
"loc": "Shed"
}, {
"id": "461",
"name": "Widget 2",
"loc": "Kitchen"
}, {
"id": "462",
"name": "Widget 3",
"loc": "bath"
}
]
};
function removeFunction (myObjects,prop,valu)
{
return myObjects.filter(function (val) {
return val[prop] !== valu;
});
}
console.log(removeFunction(obj.results,"id","460"));
rownumber() over(...) is working but I didn't like this solution for 2 reasons. - This function is not available when you using older version of SQL like SQL2000 - Dependency on function and is not really readable.
Another solution is:
SELECT tmpall.[OrderNO] ,
tmpall.[PartCode] ,
tmpall.[Quantity] ,
FROM (SELECT [OrderNO],
[PartCode],
[Quantity],
[DateEntered]
FROM you_table) AS tmpall
INNER JOIN (SELECT [OrderNO],
Max([DateEntered]) AS _max_date
FROM your_table
GROUP BY OrderNO ) AS tmplast
ON tmpall.[OrderNO] = tmplast.[OrderNO]
AND tmpall.[DateEntered] = tmplast._max_date
For me (selectionChange)
and the suggested (onSelectionChange)
didn't work and I'm not using ReactiveForms
. What I ended up doing was using the (valueChange)
event like:
<mat-select (valueChange)="someFunction()">
And this worked for me

Your web pages are served by an application pool. If you disable/stop the application pool, and anyone tries to browse the application, you will get a Service Unavailable. It can happen due to multiple reasons...
Your application may have crashed [check the event viewer and see if you can find event logs in your Application/System log]
Your application may be crashing very frequently. If an app pool crashes for 5 times in 5 minutes [check your application pool settings for rapid fail], your application pool is disabled by IIS and you will end up getting this message.
In either case, the issue is that your worker process is failing and you should troubleshoot it from crash perspective.
What is a Crash (technically)... in ASP.NET and what to do if it happens?
Default-Values are only considered for parameters NOT given to the function.
So given a function
procedure foo( bar1 IN number DEFAULT 3,
bar2 IN number DEFAULT 5,
bar3 IN number DEFAULT 8 );
if you call this procedure with no arguments then it will behave as if called with
foo( bar1 => 3,
bar2 => 5,
bar3 => 8 );
but 'NULL' is still a parameter.
foo( 4,
bar3 => NULL );
This will then act like
foo( bar1 => 4,
bar2 => 5,
bar3 => Null );
( oracle allows you to either give the parameter in order they are specified in the procedure, specified by name, or first in order and then by name )
one way to treat NULL the same as a default value would be to default the value to NULL
procedure foo( bar1 IN number DEFAULT NULL,
bar2 IN number DEFAULT NULL,
bar3 IN number DEFAULT NULL );
and using a variable with the desired value then
procedure foo( bar1 IN number DEFAULT NULL,
bar2 IN number DEFAULT NULL,
bar3 IN number DEFAULT NULL )
AS
v_bar1 number := NVL( bar1, 3);
v_bar2 number := NVL( bar2, 5);
v_bar3 number := NVL( bar3, 8);
Although other answers are correct they are setting the global config value whereas there is a default git location for the global git ignore file:
*nix:
~/.config/git/ignore
Windows:
%USERPROFILE%\git\ignore
You may need to create git
directory and ignore
file but then you can put your global ignores into that file and that's it!
Which file to place a pattern in depends on how the pattern is meant to be used.
…
- Patterns which a user wants Git to ignore in all situations (e.g., backup or temporary files generated by the user’s editor of choice) generally go into a file specified by
core.excludesFile
in the user’s~/.gitconfig
. Its default value is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore is used instead.
check this.configuration..
app = module.exports = express();
var httpsOptions = { key: fs.readFileSync('certificates/server.key'), cert: fs.readFileSync('certificates/final.crt') };
var secureServer = require('https').createServer(httpsOptions, app);
io = module.exports = require('socket.io').listen(secureServer,{pingTimeout: 7000, pingInterval: 10000});
io.set("transports", ["xhr-polling","websocket","polling", "htmlfile"]);
secureServer.listen(3000);
How about you store it like this? Maybe in username:password format, so
sebastion:password123
anotheruser:password321
Then you can use list($username,$password) = explode(':',file_get_contents('users.txt'));
to parse the data on your end.
XAMPP uses a file called mysql_start.bat to start MySQL and if you open that file with a text editor you can see what config file is trying to use, in the current version it is:
mysql\bin\mysqld --defaults-file=mysql\bin\my.ini --standalone --console
If you installed XAMPP on the default path it means it is on c:/xampp/mysql/bin/my.ini
If somehow the file doesn't exist you should open a console terminal (start-> type "cmd", press enter) and then write "mysql --help" and it prints a text mentioning the default locations, in the current version of XAMPP is:
C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf C:\xampp\mysql\my.ini C:\xampp\mysql\my.cnf
@vnr you can retrieve all the sort keys associated with a partition key by just using the query using partion key. No need of scan. The point here is partition key is compulsory in a query . Sort key are used only to get range of data

For anyone who stumbles here with the issue I had (some but not all packages being restored on a build server), the final piece of the puzzle for me was adding a NuGet.config in the root of my solution, sibling to the .SLN file as David Ebbo explained here: http://blog.davidebbo.com/2014/01/the-right-way-to-restore-nuget-packages.html.
From Ebbo's blog post, the file contents for me are simply
<?xml version="1.0" encoding="utf-8"?>
<configuration>
<packageSources>
<add key="nuget.org" value="https://www.nuget.org/api/v2/" />
</packageSources>
</configuration>
UPDATE:
The NuGet API URL has changed for v3 (current as of Sept 2016). From https://www.nuget.org/
<add key="nuget.org" value="https://api.nuget.org/v3/index.json" />
I can't get it to work on $.get()
because it has no complete
event.
I suggest to use $.ajax()
like this,
$.ajax({
url: 'http://www.example.org',
data: {'a':1,'b':2,'c':3},
dataType: 'xml',
complete : function(){
alert(this.url)
},
success: function(xml){
}
});
This works:
$string = 'A B C D';
$arr = preg_split('/[\s]+/', $string);
In my experience, it has expired at the end of that month. That is based on the fact that I can use it during that month, and that month is when my bank sends a new one.
You are loding jQuery.DataTables.js
before jquery.js
so for that :-
You need to load jQuery.js
before you load jQuery.DataTables.js
You are using two versions of jQuery.js
on the same page so for that :-
Try to use the higher version and make sure both links have same version of jQuery
You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw()
, ensure that you binding the parameters.
Try the following:
$array = array(1,2,3); $query = DB::table('offers'); $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used'); $query->leftJoin('user_offer_collection', function ($join) use ($array) { $join->on('user_offer_collection.offers_id', '=', 'offers.id') ->whereIn('user_offer_collection.user_id', $array); }); $query->get();
Most "new" things in computing aren't really new at all, they're just a mystifying wrapper around something that already well-understood. When they're hard to understand, it's usually because someone decided to invent new language terms or colonise existing terms for a different purpose (a good example of that is the X developers' reversal of what "client" and "server" mean.)
Camel is a Java-based wrapper/API for inter-application middleware.
Middleware is a general term for software that provides interpretation services between entities that don't share a common language or data types.
That's what Camel is, at bottom. We can flesh out the description by noting that it provides for EIP-type middleware.
It doesn't provide the middleware itself, since it can't know the details of what the applications need to communicate. But it provides the API for creating the invariant parts of that middleware (create a start point, create an end point, create conditions for starting and ending, etc)
Hope that helps.
In fact if you write any C extensions for your Ruby projects there is really only one way to define a Module method.
rb_define_singleton_method
I know this self business just opens up all kinds of other questions so you could do better by searching each part.
Objects first.
foo = Object.new
Can I make a method for foo?
Sure
def foo.hello
'hello'
end
What do I do with it?
foo.hello
==>"hello"
Just another object.
foo.methods
You get all the Object methods plus your new one.
def foo.self
self
end
foo.self
Just the foo Object.
Try to see what happens if you make foo from other Objects like Class and Module. The examples from all the answers are nice to play with but you have to work with different ideas or concepts to really understand what is going on with the way the code is written. So now you have lots of terms to go look at.
Singleton, Class, Module, self, Object, and Eigenclass was brought up but Ruby doesn't name Object Models that way. It's more like Metaclass. Richard or __why shows you the idea here. http://viewsourcecode.org/why/hacking/seeingMetaclassesClearly.html And if the blows you away then try looking up Ruby Object Model in search. Two videos that I know of on YouTube are Dave Thomas and Peter Cooper. They try to explain that concept too. It took Dave a long time to get it so don't worry. I'm still working on it too. Why else would I be here? Thanks for your question. Also take a look at the standard library. It has a Singleton Module just as an FYI.
This is pretty good. https://www.youtube.com/watch?v=i4uiyWA8eFk
I think what you are looking for is:
startDate.setDate(startDate.getDate() + 1);
Also, you can have a look at Moment.js
A javascript date library for parsing, validating, manipulating, and formatting dates.
