Try this:
$("#cpa-form").submit(function(e){
return false;
});
use this too :
if(e.preventDefault)
e.preventDefault();
else
e.returnValue = false;
Becoz e.preventDefault() is not supported in IE( some versions ). In IE it is e.returnValue = false

Event capturing
When you use event capturing
| | ---------------| |----------------- | element1 | | | | -----------| |----------- | | |element2 \ / | | | ------------------------- | | Event CAPTURING | -----------------------------------the event handler of element1 fires first, the event handler of element2 fires last.
Event bubbling
When you use event bubbling
/ \ ---------------| |----------------- | element1 | | | | -----------| |----------- | | |element2 | | | | | ------------------------- | | Event BUBBLING | -----------------------------------the event handler of element2 fires first, the event handler of element1 fires last.
Any event taking place in the W3C event model is first captured until it reaches the target element and then bubbles up again.
| | / \ -----------------| |--| |----------------- | element1 | | | | | | -------------| |--| |----------- | | |element2 \ / | | | | | -------------------------------- | | W3C event model | ------------------------------------------
From w3.org, for event capture:
If the capturing
EventListener
wishes to prevent further processing of the event from occurring it may call thestopPropagation
method of theEvent
interface. This will prevent further dispatch of the event, although additionalEventListeners
registered at the same hierarchy level will still receive the event. Once an event'sstopPropagation
method has been called, further calls to that method have no additional effect. If no additional capturers exist andstopPropagation
has not been called, the event triggers the appropriateEventListeners
on the target itself.
For event bubbling:
Any event handler may choose to prevent further event propagation by calling the
stopPropagation
method of theEvent
interface. If anyEventListener
calls this method, all additionalEventListeners
on the currentEventTarget
will be triggered but bubbling will cease at that level. Only one call tostopPropagation
is required to prevent further bubbling.
For event cancelation:
Cancelation is accomplished by calling the
Event
'spreventDefault
method. If one or moreEventListeners
callpreventDefault
during any phase of event flow the default action will be canceled.
In the following examples, a click on the hyperlink in the web browser triggers the event's flow (the event listeners are executed) and the event target's default action (a new tab is opened).
HTML:
<div id="a">
<a id="b" href="http://www.google.com/" target="_blank">Google</a>
</div>
<p id="c"></p>
JavaScript:
var el = document.getElementById("c");
function capturingOnClick1(ev) {
el.innerHTML += "DIV event capture<br>";
}
function capturingOnClick2(ev) {
el.innerHTML += "A event capture<br>";
}
function bubblingOnClick1(ev) {
el.innerHTML += "DIV event bubbling<br>";
}
function bubblingOnClick2(ev) {
el.innerHTML += "A event bubbling<br>";
}
// The 3rd parameter useCapture makes the event listener capturing (false by default)
document.getElementById("a").addEventListener("click", capturingOnClick1, true);
document.getElementById("b").addEventListener("click", capturingOnClick2, true);
document.getElementById("a").addEventListener("click", bubblingOnClick1, false);
document.getElementById("b").addEventListener("click", bubblingOnClick2, false);
Example 1: it results in the output
DIV event capture
A event capture
A event bubbling
DIV event bubbling
Example 2: adding stopPropagation()
to the function
function capturingOnClick1(ev) {
el.innerHTML += "DIV event capture<br>";
ev.stopPropagation();
}
results in the output
DIV event capture
The event listener prevented further downward and upward propagation of the event. However it did not prevent the default action (a new tab opening).
Example 3: adding stopPropagation()
to the function
function capturingOnClick2(ev) {
el.innerHTML += "A event capture<br>";
ev.stopPropagation();
}
or the function
function bubblingOnClick2(ev) {
el.innerHTML += "A event bubbling<br>";
ev.stopPropagation();
}
results in the output
DIV event capture
A event capture
A event bubbling
This is because both event listeners are registered on the same event target. The event listeners prevented further upward propagation of the event. However they did not prevent the default action (a new tab opening).
Example 4: adding preventDefault()
to any function, for instance
function capturingOnClick1(ev) {
el.innerHTML += "DIV event capture<br>";
ev.preventDefault();
}
prevents a new tab from opening.
just like pure js do preventdefault : in class you should like this create a handler method :
handler(event) {
event.preventDefault();
console.log(event);
}
None of the solutions helped me here and I did this to solve my situation.
<a onclick="return clickEvent(event);" href="/contact-us">
And the function clickEvent()
,
function clickEvent(event) {
event.preventDefault();
// do your thing here
// remove the onclick event trigger and continue with the event
event.target.parentElement.onclick = null;
event.target.parentElement.click();
}
After close examining, not 300k lines but there are around 3-4 CSS properties that you need to override:
.navbar-collapse.collapse {
display: block!important;
}
.navbar-nav>li, .navbar-nav {
float: left !important;
}
.navbar-nav.navbar-right:last-child {
margin-right: -15px !important;
}
.navbar-right {
float: right!important;
}
And with this your menu won't collapse.
EXPLANATION
The four CSS properties do the respective:
The default .collapse
property in bootstrap hides the right-side of the menu for tablets(landscape) and phones and instead a toggle button is displayed to hide/show it. Thus this property overrides the default and persistently shows those elements.
For the right-side menu to appear on the same line along with the left-side, we need the left-side to be floating left.
This property is present by default in bootstrap but not on tablet(portrait) to phone resolution. You can skip this one, it's likely to not affect your overall navbar.
This keeps the right-side menu to the right while the inner elements (li
) will follow the property 2. So we have left-side float left and right-side float right which brings them into one line.
if (e.preventDefault) {
e.preventDefault();
} else {
e.returnValue = false;
}
Tested on IE 9 and Chrome.
UPDATE: I've since changed my mind on this solution. After more development and time spent working on this, I believe a better solution to this problem is to do the following:
<a ng-click="myFunction()">Click Here</a>
And then update your css
to have an extra rule:
a[ng-click]{
cursor: pointer;
}
Its much more simple and provides the exact same functionality and is much more efficient. Hope that might be helpful to anyone else looking up this solution in the future.
The following is my previous solution, which I am leaving here just for legacy purposes:
If you are having this problem a lot, a simple directive that would fix this issue is the following:
app.directive('a', function() {
return {
restrict: 'E',
link: function(scope, elem, attrs) {
if(attrs.ngClick || attrs.href === '' || attrs.href === '#'){
elem.on('click', function(e){
e.preventDefault();
});
}
}
};
});
It checks all anchor tags (<a></a>
) to see if their href
attribute is either an empty string (""
) or a hash ('#'
) or there is an ng-click
assignment. If it finds any of these conditions, it catches the event and prevents the default behavior.
The only down side is that it runs this directive for all anchor tags. So if you have a lot of anchor tags on the page and you only want to prevent the default behavior for a small number of them, then this directive isn't very efficient. However, I almost always want to preventDefault
, so I use this directive all over in my AngularJS apps.
If the element only has one handler, then simply use jQuery unbind.
$("#element").unbind();
A solution that worked for me is using the hidden input field in the template
<input type="hidden" id="myVar" name="variable" value="{{ variable }}">
Then getting the value in javascript this way,
var myVar = document.getElementById("myVar").value;
0xe0434352 is the SEH code for a CLR exception. If you don't understand what that means, stop and read A Crash Course on the Depths of Win32™ Structured Exception Handling. So your process is not handling a CLR exception. Don't shoot the messenger, KERNELBASE.DLL is just the unfortunate victim. The perpetrator is MyApp.exe.
There should be a minidump of the crash in DrWatson folders with a full stack, it will contain everything you need to root cause the issue.
I suggest you wire up, in your myapp.exe code, AppDomain.UnhandledException
and Application.ThreadException
, as appropriate.
As thirtydot said, you can use the CSS3 background-size
syntax:
For example:
-o-background-size:35% auto;
-webkit-background-size:35% auto;
-moz-background-size:35% auto;
background-size:35% auto;
However, as also stated by thirtydot, this does not work in IE6, 7 and 8.
See the following links for more information about background-size
:
http://www.w3.org/TR/css3-background/#the-background-size
It's not clear how you want your Date logic to behave? Usually a good way to deal with default behaviour is the Null Object pattern.
what about creating a stub node (document.createElement('div') - or using your library equivalent), filling it with the xml string (via innerHTML) and calling simple recursive function for the root element/or the stub element in case you don't have a root. The function would call itself for all the child nodes.
You could then syntax-highlight along the way, be certain the markup is well-formed (done automatically by browser when appending via innerHTML) etc. It wouldn't be that much code and probably fast enough.
you don't, declare an interface that declares the methods you would like to call:
public interface MyInterface
{
void doStuff();
}
public class MyClass implements MyInterface
{
public void doStuff()
{
System.Console.Writeln("done!");
}
}
then you use
MyInterface mobj = (myInterface)obj;
mobj.doStuff();
If MyClass
is not under your control then you can't make it implement some interface, and the other option is to rely on reflection (see this tutorial).
I used Rafid's suggestion of using AJAX.
This worked for me:
var url = "http://www.example.com/file.json";
var jsonFile = new XMLHttpRequest();
jsonFile.open("GET",url,true);
jsonFile.send();
jsonFile.onreadystatechange = function() {
if (jsonFile.readyState== 4 && jsonFile.status == 200) {
document.getElementById("id-of-element").innerHTML = jsonFile.responseText;
}
}
I basically(almost literally) copied this code from http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_get2 so credit to them for everything.
I dont have much knowledge of how this works but you don't have to know how your brakes work to use them ;)
Hope this helps!
Here is a simple analogy; Imagine you are downloading movies online, with O(1), if it takes 5 minutes to download one movie, it will still take the same time to download 20 movies. So it doesn't matter how many movies you are downloading, they will take the same time(5 minutes) whether it's one or 20 movies. A normal example of this analogy is when you go to a movie library, whether you are taking one movie or 5, you will simply just pick them at once. Hence spending the same time.
However, with O(n), if it takes 5 minutes to download one movie, it will take about 50 minutes to download 10 movies. So time is not constant or is somehow proportional to the number of movies you are downloading.
Use the formatting operator %

buf = "A = %d\n , B= %s\n" % (a, b)
print >>f, buf

OR (pretty print)
System.out.printf("0x%02X", test[0]);
OR (pretty print)
System.out.println(String.format("0x%02X", test[0]));

If the <div>
has id or name then you can use find_element_by_id
or find_element_by_name
You can also try with class name, css and xpath
find_element_by_class_name
find_element_by_css_selector
find_element_by_xpath
This will give you some control over the clicking, and looks tidy

To add to advice already given, if you have a web app running through IIS that uses the DB, you may also need to stop (not recycle) the app pool for the app while you restore, then re-start. Stopping the app pool kills off active http connections and doesn't allow any more, which could otherwise end up allowing processes to be triggered that connect to and thereby lock the database. This is a known issue for example with the Umbraco Content Management System when restoring its database
Answer using TypeScript spread operator (...)

const key = 'two';
// Your array
const arr = [
'one',
'two',
'three'
];
// Get either the index or -1
const index = arr.indexOf(key); // returns 0
// Despite a real index, or -1, use spread operator and Array.prototype.slice()
const newArray = (index > -1) ? [
...arr.slice(0, index),
...arr.slice(index + 1)
] : arr;
There is a new way to do this in iOS 11+ (new app store). You can open the "Write a Review" dialog directly.
iOS 11 example:
itms-apps://itunes.apple.com/us/app/id1137397744?action=write-review
or
https://itunes.apple.com/us/app/id1137397744?action=write-review
Notes:
/us/
). It can be any country code, doesn't matter.1137397744
) to your app id (get it from iTunes URL).Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.
server {
listen 80;
server_name localhost;
access_log logs/localhost.access.log main;
location / {
root /var/www/board/public;
index index.html index.htm index.php;
}

Adding this option for dealing with basic uint8 to byte[] conversion
foo := 255 // 1 - 255
ufoo := uint16(foo)
far := []byte{0,0}
binary.LittleEndian.PutUint16(far, ufoo)
bar := int(far[0]) // back to int
fmt.Println("foo, far, bar : ",foo,far,bar)
output :
foo, far, bar : 255 [255 0] 255
I faced this problem a few days ago - the solution for me was to use .bind() to bind the required function to the dynamically created link.
var catLink = $('<a href="#" id="' + i + '" class="lnkCat">' + category.category + '</a>');
catLink.bind("click", function(){
$.categories.getSubCategories(this);
});
getSubCategories : function(obj) {
//do something
}
I hope this helps.

For some reasons, Webkit-based browsers don't follow the spec for the dialog box. An almost cross-working example would be close from the below example.
window.addEventListener("beforeunload", function (e) {
var confirmationMessage = "\o/";
(e || window.event).returnValue = confirmationMessage; //Gecko + IE
return confirmationMessage; //Webkit, Safari, Chrome
});
This example for handling all browsers.
If you create a tag by e.g.
git tag v1.0
the tag will refer to the most recent commit of the branch you are currently on. You can change branch and create a tag there.
You can also just refer to the other branch while tagging,
git tag v1.0 name_of_other_branch
which will create the tag to the most recent commit of the other branch.
Or you can just put the tag anywhere, no matter which branch, by directly referencing to the SHA1 of some commit
git tag v1.0 <sha1>

Here is a snippet for not only closing modals without page refresh but when pressing enter it submits modal and closes without refresh
I have it set up on my site where I can have multiple modals and some modals process data on submit and some don't. What I do is create a unique ID for each modal that does processing. For example in my webpage:
HTML (modal footer):
<div class="modal-footer form-footer"><br>
<span class="caption">
<button id="PreLoadOrders" class="btn btn-md green btn-right" type="button" disabled>Add to Cart <i class="fa fa-shopping-cart"></i></button>
<button id="ClrHist" class="btn btn-md red btn-right" data-dismiss="modal" data-original-title="" title="Return to Scan Order Entry" type="cancel">Cancel <i class="fa fa-close"></i></a>
</span>
</div>
jQUERY:
$(document).ready(function(){
// Allow enter key to trigger preloadorders form
$(document).keypress(function(e) {
if(e.which == 13) {
e.preventDefault();
if($(".trigger").is(".ok"))
$("#PreLoadOrders").trigger("click");
else
return;
}
});
});
As you can see this submit performs processing which is why I have this jQuery for this modal. Now let's say I have another modal within this webpage but no processing is performed and since one modal is open at a time I put another $(document).ready()
in a global php/js script that all pages get and I give the modal's close button a class called: ".modal-close"
:
HTML:
<div class="modal-footer caption">
<button type="submit" class="modal-close btn default" data-dismiss="modal" aria-hidden="true">Close</button>
</div>
jQuery (include global.inc):
$(document).ready(function(){
// Allow enter key to trigger a particular button anywhere on page
$(document).keypress(function(e) {
if(e.which == 13) {
if($(".modal").is(":visible")){
$(".modal:visible").find(".modal-close").trigger('click');
}
}
});
});
Try this.
public static void main(String[] args) {
EchoServer0 myServer;
myServer = new EchoServer0();
myServer.listen();
}
What you were trying to do was declaring a variable of type Object
, not creating anything for that variable to reference, then trying to call a method that didn't exist (in the class Object
) on an object that hadn't been created. It was never going to work.
Send the email to a real SMTP server. If you don't want to set up your own then you can find companies that will run one for you, such as Google themselves.
try this
SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy HH:mm:ss");
String string = dateFormat.format(new Date());
System.out.println(string);
you can create any format see this
msbuild "C:\path to solution\project.sln"
I´ve done a tiny solution using only jQuery.
First, you need to put an additional class to your <div class="modal-body">
I called "ativa-scroll", so it becomes something like this:
<div class="modal-body ativa-scroll">
So now just put this piece of code on your page, near your JS loading:
<script type="text/javascript">
$(document).ready(ajustamodal);
$(window).resize(ajustamodal);
function ajustamodal() {
var altura = $(window).height() - 155; //value corresponding to the modal heading + footer
$(".ativa-scroll").css({"height":altura,"overflow-y":"auto"});
}
</script>
I works perfectly for me, also in a responsive way! :)
I had a similar warning/error/failure when I was simply trying to make an executable from two different object files (main.o and add.o). I was using the command:
gcc -o exec main.o add.o
But my program is a C++ program. Using the g++
compiler solved my issue:
g++ -o exec main.o add.o
I was always under the impression that gcc
could figure these things out on its own. Apparently not. I hope this helps someone else searching for this error.
Or you can convert it into Char Array first by:
string Something = "1,5,12,34,";
char[] SomeGoodThing=Something.ToCharArray[];
Now you have each character indexed
:
SomeGoodThing[0] -> '1'
SomeGoodThing[1] -> ','
Play around it

public int compare(myObject o1, myObject o2) {
try {
return simpleDateFormat.parse(o2.getCreated_at()).compareTo(simpleDateFormat.parse(o1.getCreated_at()));
} catch (ParseException e) {
e.printStackTrace();
return 0;
}
}
});
}
If Object(Model Class/POJO) contains date in Date datatype
private void sortArray(ArrayList<myObject> arrayList) {
if (arrayList != null) {
Collections.sort(arrayList, new Comparator<myObject>() {
@Override
public int compare(myObject o1, myObject o2) {
return o2.getCreated_at().compareTo(o1.getCreated_at()); }
});
} }
The above code is for sorting the array in descending order of date, swap o1 and o2 for ascending order.
In jQuery documentation it says:
The matching text can appear directly within the selected element, in any of that element's descendants, or a combination
Therefore it is not enough that you use :contains()
selector, you also need to check if the text you search for is the direct content of the element you are targeting for, something like that:
function findElementByText(text) {
var jSpot = $("b:contains(" + text + ")")
.filter(function() { return $(this).children().length === 0;})
.parent(); // because you asked the parent of that element
return jSpot;
}
<a href="javascript:void(0)" class="aaf" id="users_id">add as a friend</a>
on jquery
$('.aaf').on("click",function(){
var usersid = $(this).attr("id");
//post code
})
//other method is to use the data attribute
<a href="javascript:void(0)" class="aaf" data-id="102" data-username="sample_username">add as a friend</a>
on jquery
$('.aaf').on("click",function(){
var usersid = $(this).data("id");
var username = $(this).data("username");
})
Add this in the head section of your html
<link rel="icon" type="image/gif/png" href="mouse_select_left.png">
If you just want to get the information of current directory, you can type:
pwd
and you don't need to use the Nautilus, or you can use a teamviewer software to remote connect to the computer, you can get everything you want.
I think that this one is the simplest one and it accepts European and USA way of writing numbers e.g. USA 10,555.12 European 10.555,12 Also this one does not allow several commas or dots one after each other e.g. 10..22 or 10,.22 In addition to this numbers like .55 or ,55 would pass. This may be handy.

Here is my approach:
var preloadImages = function (srcs, imgs, callback) {
var img;
var remaining = srcs.length;
for (var i = 0; i < srcs.length; i++) {
img = new Image;
img.onload = function () {
--remaining;
if (remaining <= 0) {
callback();
}
};
img.src = srcs[i];
imgs.push(img);
}
};
Rather than importing all of curses or shelling out just to get one control character, you can simply use (on Linux/macOS):
print(chr(27) + "[2J")
(Source: Clear terminal in Python)
Use ROW_NUMBER()
instead. ROWNUM
is a pseudocolumn and ROW_NUMBER()
is a function. You can read about difference between them and see the difference in output of below queries:
SELECT * FROM (SELECT rownum, deptno, ename
FROM scott.emp
ORDER BY deptno
)
WHERE rownum <= 3
/
ROWNUM DEPTNO ENAME
---------------------------
7 10 CLARK
14 10 MILLER

(
SELECT deptno, ename

From the documentation Restore activity UI state using saved instance state it is stated as:
Instead of restoring the state during onCreate() you may choose to implement onRestoreInstanceState(), which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null:
IMO, this is more clear way than checking this at onCreate, and better fits with single responsiblity principle.
The accepted answer is not ideal, so I decided to add my 2 cents
timeStamp.toLocalDateTime().toLocalDate();
is a bad solution in general, I'm not even sure why they added this method to the JDK as it makes things really confusing by doing an implicit conversion using the system timezone. Usually when using only java8 date classes the programmer is forced to specify a timezone which is a good thing.
The good solution is
timestamp.toInstant().atZone(zoneId).toLocalDate()
Where zoneId is the timezone you want to use which is typically either ZoneId.systemDefault() if you want to use your system timezone or some hardcoded timezone like ZoneOffset.UTC
The general approach should be
I use this routine to find the count of data rows. There is a minimum of overhead required, but by counting using a decreasing scale, even a very large result requires few iterations. For example, a result of 28,395 would only require 2 + 8 + 3 + 9 + 5, or 27 times through the loop, instead of a time-expensive 28,395 times.
Even were we to multiply that by 10 (283,950), the iteration count is the same 27 times.

YapDi is a relatively new python module that popped up in Hacker News. Looks pretty useful, can be used to convert a python script into daemon mode from inside the script.
this is how:
/**
* Get a web file (HTML, XHTML, XML, image, etc.) from a URL. Return an
* array containing the HTTP server response header fields and content.
*/
function get_web_page( $url )
{
$user_agent='Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0';
$options = array(
CURLOPT_CUSTOMREQUEST =>"GET", //set request type post or get
CURLOPT_POST =>false, //set to GET
CURLOPT_USERAGENT => $user_agent, //set user agent
CURLOPT_COOKIEFILE =>"cookie.txt", //set cookie file
CURLOPT_COOKIEJAR =>"cookie.txt", //set cookie jar
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers
CURLOPT_FOLLOWLOCATION => true, // follow redirects

CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect

Be aware that a lot of the really killer features are only in Enterprise Edition. Data compression and backup compression are among two of my top favorites - they give you free performance improvements right off the bat. Data compression lessens the amount of I/O you have to do, so a lot of queries speed up 20-40%. CPU use goes up, but in today's multi-core environments, we often have more CPU power but not more IO. Anyway, those are only in Enterprise.
If you're only going to use Standard Edition, then most of the improvements require changes to your application code and T-SQL code, so it's not quite as easy of a sell.
sample fiddle: http://jsfiddle.net/z68VD/
html:
<form id="uguu" action="http://google.ca">
<input type="submit" value="text 1" />
</form>
jquery:
$("#uguu").submit(function() {
if ($("input[type='submit']").val() == "text 1") {
alert("Please confirm if everything is correct");
$("input[type='submit']").val("text 2");
return false;
}
});
This is more a workaround than a real solution. You can create a new object test_data
with another column name:
left_join("names<-"(test_data, "name"), kantrowitz, by = "name")
name gender
1 john M
2 bill either
3 madison M
4 abby either
5 zzz <NA>
You can also use something like:
imageView.setImageDrawable(ActivityCompat.getDrawable(getContext(),
R.drawable.generatedID));
or using Picasso:
Picasso.with(getContext()).load(R.drawable.generatedId).into(imageView);
I've interpreted this question as:
"Can anyone tell me how to pass values for JavaScript for use in a JSP?"
If that's the case, this HTML file would pass a server-calculated variable to a JavaScript in a JSP.
<html>
<body>
<script type="text/javascript">
var serverInfo = "<%=getServletContext().getServerInfo()%>";
alert("Server information " + serverInfo);
</script>
</body>
</html>
I know this is an old thread but what solved the issue for me was adding the following to my build.gradle files.
As already stated above there is a compatibility issue with mockito-all
Possibly useful post:
testCompile ('junit:junit:4.12') {
exclude group: 'org.hamcrest'

While iterating through the loop, you are trying to change the List value in the remove() operation. This will result in ConcurrentModificationException.
Follow the below code, which will achieve what you want and yet will not throw any exceptions
private String toString(List aDrugStrengthList) {
StringBuilder str = new StringBuilder();
List removalList = new ArrayList();
for (DrugStrength aDrugStrength : aDrugStrengthList) {
if (!aDrugStrength.isValidDrugDescription()) {
removalList.add(aDrugStrength);
}
}
aDrugStrengthList.removeAll(removalList);
str.append(aDrugStrengthList);
if (str.indexOf("]") != -1) {
str.insert(str.lastIndexOf("]"), "\n " );
}
return str.toString();
}
I know it's been a long time since the guy posted this question, but I had the same question and this post didn't give me the answer. I wanted an easy way to see what the number represents, easy comparison, and most of all ActiveRecord support for lookup using the column representing the enum.
I didn't find anything, so I made an awesome implementation called yinum which allowed everything I was looking for. Made ton of specs, so I'm pretty sure it's safe.
Some example features:
COLORS = Enum.new(:COLORS, :red => 1, :green => 2, :blue => 3)
=> COLORS(:red => 1, :green => 2, :blue => 3)
COLORS.red == 1 && COLORS.red == :red
=> true
class Car < ActiveRecord::Base
attr_enum :color, :COLORS, :red => 1, :black => 2
end
car = Car.new
car.color = :red / "red" / 1 / "1"
car.color
=> Car::COLORS.red
car.color.black?
=> false
Car.red.to_sql
=> "SELECT `cars`.* FROM `cars` WHERE `cars`.`color` = 1"
Car.last.red?
=> true
I would imagine Google grabs some data server-side - remember, when a page loads into your browser that has Google Analytics code within it, your browser makes a request to Google's servers; Google can obtain data in that way as well as through the JavaScript embedded in the page.
I remember the StaticSelectedStyle-CssClass attribute used to work in ASP.NET 2.0. And in .NET 4.0 if you change the Menu control's RenderingMode attribute "Table" (thus making it render the menu as s and sub-s like it did back '05) it will at least write your specified StaticSelectedStyle-CssClass into the proper html element.
That may be enough for you page to work like you want. However my work-around for the selected menu item in ASP 4.0 (when leaving RenderingMode to its default), is to mimic the control's generated "selected" CSS class but give mine the "!important" CSS declaration so my styles take precedence where needed.
For instance by default the Menu control renders an "li" element and child "a" for each menu item and the selected menu item's "a" element will contain class="selected" (among other control generated CSS class names including "static" if its a static menu item), therefore I add my own selector to the page (or in a separate stylesheet file) for "static" and "selected" "a" tags like so:
a.selected.static
{
background-color: #f5f5f5 !important;
border-top: Red 1px solid !important;
border-left: Red 1px solid !important;
border-right: Red 1px solid !important;
}
Use Memoize
The op's derivation of state is a direct manipulation of props, with no true derivation needed. In other words, if you have a prop which can be utilized or transformed directly there is no need to store the prop on state.
Given that the state value of start_time
is simply the prop start_time.format("HH:mm")
, the information contained in the prop is already in itself sufficient for updating the component.
However if you did want to only call format on a prop change, the correct way to do this per latest documentation would be via Memoize: https://reactjs.org/blog/2018/06/07/you-probably-dont-need-derived-state.html#what-about-memoization
a = Array.new(Array.new(4))
0.upto(a.length-1) do |i|
0.upto(a.length-1) do |j|
a[i[j]] = 1
end
end
0.upto(a.length-1) do |i|
0.upto(a.length-1) do |j|
print a[i[j]] = 1 #It's not a[i][j], but a[i[j]]
end
puts "\n"

Change your input to a button element and you can use the Font Awesome classes on it. The alignment of the glyph isn't great in the demo, but you get the idea:
<div id="search-bar">
<form method="get" action="search.php" autocomplete="off" name="form_search">
<input type="hidden" name="type" value="videos" />
<input autocomplete="on" id="keyword" name="keyword" value="Search Videos" onclick="clickclear(this,
'Search Videos')" onblur="clickrecall(this,'Search Videos')" style="font-family: verdana; font-weight:bold;
font-size: 10pt; height: 28px; width:186px; color: #000000; padding-left: 2px; border: 1px solid black; background-color:
#ffffff" /><!--
--><button class="icon-search">Search</button>
<div id="searchBoxSuggestions"></div>
</form>
</div>
#search-bar .icon-search {
width: 30px;
height: 30px;
background: black;
color: white;
border: none;
overflow: hidden;
vertical-align: middle;
padding: 0;
}
#search-bar .icon-search:before {
display: inline-block;
width: 30px;
height: 30px;
}
The advantage here is that the form is still fully functional without having to add event handlers for elements that aren't buttons but look like one.
Several of the answers on this page are 'single use' fixes to the described problem. Meaning, the next time you open a document with vim, the previous tab settings will return.
If anyone is interested in permanently changing the tab settings:
add the following lines: (more info here)
set tabstop=4 set shiftwidth=4 set expandtab
then save file and test
/// <summary>
/// Given two list, compare and extract differences
/// http://stackoverflow.com/questions/5620266/the-opposite-of-intersect
/// </summary>
public class CompareList
{
/// <summary>
/// Returns list of items that are in initial but not in final list.
/// </summary>
/// <param name="listA"></param>
/// <param name="listB"></param>
/// <returns></returns>
public static IEnumerable<string> NonIntersect(
List<string> initial, List<string> final)
{
//subtracts the content of initial from final
//assumes that final.length < initial.length
return initial.Except(final);
}
/// <summary>
/// Returns the symmetric difference between the two list.
/// http://en.wikipedia.org/wiki/Symmetric_difference

public static IEnumerable<string> SymmetricDifference(
List<string> initial, List<string> final)
{
IEnumerable<string> setA = NonIntersect(final, initial);
IEnumerable<string> setB = NonIntersect(initial, final);
// sum and return the two set.
return setA.Concat(setB);
}
}
It turns out the best solution for me here was to just reformat the drive. Once reformatted all these problems were no longer problems.
Import HttpModule
in your app.module.ts file.
import { HttpModule } from '@angular/http';
import { YourHttpTestService } from '../services/httpTestService';
Also remember to declare HttpModule under imports like below:
imports: [
BrowserModule,
HttpModule
],
put these in values/colors.xml
<resources>
<color name="light_font">#FBFBFB</color>
<color name="grey_font">#ff9e9e9e</color>
<color name="text_shadow">#7F000000</color>
<color name="text_shadow_white">#FFFFFF</color>
</resources>
Then in your layout xml here are some example TextView's
Example of Floating text on Light with Dark shadow
<TextView android:id="@+id/txt_example1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14sp"
android:textStyle="bold"
android:textColor="@color/light_font"
android:shadowColor="@color/text_shadow"
android:shadowDx="1"
android:shadowDy="1"
android:shadowRadius="2" />
Example of Etched text on Light with Dark shadow
<TextView android:id="@+id/txt_example2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14sp"
android:textStyle="bold"
android:textColor="@color/light_font"
android:shadowColor="@color/text_shadow"
android:shadowDx="-1"
android:shadowDy="-1"
android:shadowRadius="1" />
Example of Crisp text on Light with Dark shadow
<TextView android:id="@+id/txt_example3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="14sp"
android:textStyle="bold"
android:textColor="@color/grey_font"
android:shadowColor="@color/text_shadow_white"
android:shadowDx="-2"
android:shadowDy="-2"
android:shadowRadius="1" />
Notice the positive and negative values... I suggest to play around with the colors/values yourself but ultimately you can adjust these settings to get the effect your looking for.
Just create a small delete function which can help you to achieve this task, I have tested this code and it runs perfectly well.
This function deletes files older than 90 days as well as a file with extension .zip to be deleted from a folder.
Private Sub DeleteZip()
Dim eachFileInMydirectory As New DirectoryInfo("D:\Test\")
Dim fileName As IO.FileInfo
Try
For Each fileName In eachFileInMydirectory.GetFiles
If fileName.Extension.Equals("*.zip") AndAlso (Now - fileName.CreationTime).Days > 90 Then
fileName.Delete()
End If
Next
Catch ex As Exception
WriteToLogFile("No Files older than 90 days exists be deleted " & ex.Message)
End Try
End Sub

Following applies to IIS 7
The error is trying to tell you that one of two things is not working properly:
See the following link for instructions on how to diagnose and fix the above issues.
http://support.microsoft.com/kb/942062/en-us
If neither of these issues is the problem, another thing to check is to make sure that the application pool configured for your website (under IIS Manager, select your website, and click "Basic Settings" on the far right) is configured with the same .Net framework version (in IIS Manager, under "Application Pools") as the targetFramework configured in your web.config, e.g.:
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<httpRuntime targetFramework="4.0" />
</system.web>
I'm not sure why this would generate such a seemingly unrelated error message, but it did for me.
To see your key on Ubuntu, just enter the following command on your terminal:
ssh-add -l
You will get an output like this:
2568 0j:20:4b:88:a7:9t:wd:19:f0:d4:4y:9g:27:cf:97:23
yourName@ubuntu (RSA)
If however you get an error like; Could not open a connection to your authentication agent.
Then it means that ssh-agent is not running. You can start/run it with:
ssh-agent bash
(thanks to @Richard in the comments) and then re-run ssh-add -l
I use Unicode Character Highlighter

Another poossible solution is based on the array_search()
function. You need to use PHP 5.5.0 or higher.
$userdb=Array
(
(0) => Array
(
(uid) => '100',
(name) => 'Sandra Shush',
(url) => 'urlof100'
),
(1) => Array
(
(uid) => '5465',
(name) => 'Stefanie Mcmohn',
(pic_square) => 'urlof100'
),
(2) => Array
(
(uid) => '40489',
(name) => 'Michael',
(pic_square) => 'urlof40489'
)
);
$key = array_search(40489, array_column($userdb, 'uid'));
echo ("The key is: ".$key);
//This will output- The key is: 2
The function array_search()
has two arguments. The first one is the value that you want to search. The second is where the function should search. The function array_column()
gets the values of the elements which key is 'uid'
.
So you could use it as:
array_search('breville-one-touch-tea-maker-BTM800XL', array_column($products, 'slug'));
or, if you prefer:
// define function
function array_search_multidim($array, $column, $key){
return (array_search($key, array_column($array, $column)));
}
// use it
array_search_multidim($products, 'slug', 'breville-one-touch-tea-maker-BTM800XL');
The original example(by xfoxawy) can be found on the DOCS.
The array_column()
page.
Update
Due to Vael comment I was curious, so I made a simple test to meassure the performance of the method that uses array_search
and the method proposed on the accepted answer.
I created an array which contained 1000 arrays, the structure was like this (all data was randomized):
[
{
"_id": "57fe684fb22a07039b3f196c",
"index": 0,
"guid": "98dd3515-3f1e-4b89-8bb9-103b0d67e613",
"isActive": true,
"balance": "$2,372.04",
"picture": "http://placehold.it/32x32",
"age": 21,
"eyeColor": "blue",
"name": "Green",
"company": "MIXERS"
},...
]
I ran the search test 100 times searching for different values for the name field, and then I calculated the mean time in milliseconds. Here you can see an example.
Results were that the method proposed on this answer needed about 2E-7 to find the value, while the accepted answer method needed about 8E-7.
Like I said before both times are pretty aceptable for an application using an array with this size. If the size grows a lot, let's say 1M elements, then this little difference will be increased too.
Update II
I've added a test for the method based in array_walk_recursive
which was mentionend on some of the answers here. The result got is the correct one. And if we focus on the performance, its a bit worse than the others examined on the test. In the test, you can see that is about 10 times slower than the method based on array_search
. Again, this isn't a very relevant difference for the most of the applications.
Update III
Thanks to @mickmackusa for spotting several limitations on this method:
Here are a few simple examples to see the difference in action:
See the list of numbers here:
nums = [1, 9, -3, 4, 8, 5, 7, 14]
When calling sorted
on this list, sorted
will make a copy of the list. (Meaning your original list will remain unchanged.)
Let's see.
sorted(nums)
returns
[-3, 1, 4, 5, 7, 8, 9, 14]
Looking at the nums
again
nums
We see the original list (unaltered and NOT sorted.). sorted
did not change the original list
[1, 2, -3, 4, 8, 5, 7, 14]
Taking the same nums
list and applying the sort
function on it, will change the actual list.
Let's see.
Starting with our nums
list to make sure, the content is still the same.
nums
[-3, 1, 4, 5, 7, 8, 9, 14]
nums.sort()
Now the original nums list is changed and looking at nums we see our original list has changed and is now sorted.
nums
[-3, 1, 2, 4, 5, 7, 8, 14]
No, it is not okay to put a link
element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):
“This element defines a link. Unlike
A
, it may only appear in theHEAD
section of a document, although it may appear any number of times.”
There is already an AI implementation for this game here. Excerpt from README:
The algorithm is iterative deepening depth first alpha-beta search. The evaluation function tries to keep the rows and columns monotonic (either all decreasing or increasing) while minimizing the number of tiles on the grid.
There is also a discussion on Hacker News about this algorithm that you may find useful.
Use the str.isspace()
method:
Return
True
if there are only whitespace characters in the string and there is at least one character,False
otherwise.A character is whitespace if in the Unicode character database (see unicodedata), either its general category is Zs (“Separator, space”), or its bidirectional class is one of WS, B, or S.
Combine that with a special case for handling the empty string.
Alternatively, you could use str.strip()
and check if the result is empty.
Use enumerate()
like so:
def draw_menu(options, selected_index):
for counter, option in enumerate(options):
if counter == selected_index:
print " [*] %s" % option
else:
print " [ ] %s" % option
options = ['Option 0', 'Option 1', 'Option 2', 'Option 3']
draw_menu(options, 2)
Note: You can optionally put parenthesis around counter, option
, like (counter, option)
, if you want, but they're extraneous and not normally included.
If you are sending this through your own mail server you might need to add a "Sender" header which will contain an email address of from your own domain. Gmail will probably be spamming the email because the FROM address is a gmail address but has not been sent from their own server.

As joe mentioned, creating the shell script and then creating an applescript script to call the shell script, will accomplish this, and is quite handy.
Create your shell script in your favorite text editor, for example:
mono "/Volumes/Media/~Users/me/Software/keepass/keepass.exe"
(this runs the w32 executable, using the mono framework)
Save shell script, for my example "StartKeepass.sh"
Open AppleScript Editor, and call the shell script
do shell script "sh /Volumes/Media/~Users/me/Software/StartKeepass.sh" user name "<enter username here>" password "<Enter password here>" with administrator privileges
do shell script
- applescript command to call external shell commands"sh ...."
- this is your shell script (full path) created in step one (you can also run direct commands, I could omit the shell script and just run my mono command here)user name
- declares to applescript you want to run the command as a specific user"<enter username here>
- replace with your username (keeping quotes) ex "josh"password
- declares to applescript your password"<enter password here>"
- replace with your password (keeping quotes) ex "mypass"with administrative privileges
- declares you want to run as an adminsave your applescript as filename.scpt, in my case RunKeepass.scpt
save as... your applescript and change the file format to application, resulting in RunKeepass.app in my case

You could pass an object as attribute and read it into the directive like this:
<div my-directive="{id:123,name:'teo',salary:1000,color:red}"></div>
app.directive('myDirective', function () {
return {
link: function (scope, element, attrs) {
//convert the attributes to object and get its properties
var attributes = scope.$eval(attrs.myDirective);
console.log('id:'+attributes.id);
console.log('id:'+attributes.name);
}
};
});
You would use the focus
and blur
events of the window:
var interval_id;
$(window).focus(function() {
if (!interval_id)
interval_id = setInterval(hard_work, 1000);
});
$(window).blur(function() {
clearInterval(interval_id);
interval_id = 0;
});
To Answer the Commented Issue of "Double Fire" and stay within jQuery ease of use:
$(window).on("blur focus", function(e) {
var prevType = $(this).data("prevType");
if (prevType != e.type) { // reduce double fire issues
switch (e.type) {
case "blur":
// do work
break;
case "focus":
// do work
break;
}
}
$(this).data("prevType", e.type);
})

0
and 7
both stand for Sunday, you can use the one you want, so writing 0-6 or 1-7 has the same result.
Also, as suggested by @Henrik, it is possible to replace numbers by shortened name of days, such as MON
, THU
, etc:
0 - Sun Sunday
1 - Mon Monday
2 - Tue Tuesday
3 - Wed Wednesday
4 - Thu Thursday
5 - Fri Friday
6 - Sat Saturday
7 - Sun Sunday
Graphically:
+---------- minute (0 - 59)
¦ +-------- hour (0 - 23)
¦ ¦ +------ day of month (1 - 31)
¦ ¦ ¦ +---- month (1 - 12)
¦ ¦ ¦ ¦ +-- day of week (0 - 6 => Sunday - Saturday, or
¦ ¦ ¦ ¦ ¦ 1 - 7 => Monday - Sunday)
? ? ? ? ?
* * * * * command to be executed
Finally, if you want to specify day by day, you can separate days with commas, for example SUN,MON,THU
will exectute the command only on sundays, mondays on thursdays.
You can read further details in Wikipedia's article about Cron.
I am suggesting a much simpler utility I just wrote. It's currently called par, but will be renamed soon to either parl or pll, haven't decided yet.
API is as simple as:
par "script1.sh" "script2.sh" "script3.sh"
Prefixing commands can be done via:
par "PARPREFIX=[script1] script1.sh" "script2.sh" "script3.sh"
This takes care of nulls
var body = JObject.Parse("anyjsonString");
body?.SelectToken("path-string-prop")?.ToString();
body?.SelectToken("path-double-prop")?.ToObject<double>();
Just for reference if someone is still looking on how to do this for multiple files, see the linked answer to Finding matching lines across many files.
Combining these two answers (ans1 and ans2), I think you can get the result you are needing without sorting the files:
#!/bin/bash
ans="matching_lines"
for file1 in *
do
for file2 in *
do
if [ "$file1" != "$ans" ] && [ "$file2" != "$ans" ] && [ "$file1" != "$file2" ] ; then
echo "Comparing: $file1 $file2 ..." >> $ans
perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/' $file1 $file2 >> $ans
fi
done
done
Simply save it, give it execution rights (chmod +x compareFiles.sh
) and run it. It will take all the files present in the current working directory and will make an all-vs-all comparison leaving in the "matching_lines" file the result.
Things to be improved:
I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..
1. onBindViewHolder() methods never got called. --> Problem 1.
2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.
Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.
Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it.
To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager
and paste the code below into it. NO CHANGES REQUIRED
public class CustomLinearLayoutManager extends LinearLayoutManager {
private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();
public CustomLinearLayoutManager(Context context) {
super(context);
}
public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
super(context, orientation, reverseLayout);
}

public void onMeasure(RecyclerView.Recycler recycler, RecyclerView.State state, int widthSpec, int heightSpec) {

int width = 0;
int height = 0;
for (int i = 0; i < getItemCount(); i++) {
measureScrapChild(recycler, i, View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
View.MeasureSpec.makeMeasureSpec(i, View.MeasureSpec.UNSPECIFIED),
mMeasuredDimension);
if (getOrientation() == HORIZONTAL) {
width = width + mMeasuredDimension[0];
if (i == 0) {
height = mMeasuredDimension[1];
}
} else {
height = height + mMeasuredDimension[1];
if (i == 0) {
width = mMeasuredDimension[0];
}
}
}
switch (widthMode) {
case View.MeasureSpec.EXACTLY:
width = widthSize;
case View.MeasureSpec.AT_MOST:
case View.MeasureSpec.UNSPECIFIED:
}
switch (heightMode) {
case View.MeasureSpec.EXACTLY:
height = heightSize;
case View.MeasureSpec.AT_MOST:
case View.MeasureSpec.UNSPECIFIED:
}
setMeasuredDimension(width, height);
}
private void measureScrapChild(RecyclerView.Recycler recycler, int position, int widthSpec,
int heightSpec, int[] measuredDimension) {
try {
View view = recycler.getViewForPosition(position);
if (view != null) {
RecyclerView.LayoutParams p = (RecyclerView.LayoutParams) view.getLayoutParams();
int childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec,
getPaddingLeft() + getPaddingRight(), p.width);
int childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec,
getPaddingTop() + getPaddingBottom(), p.height);
view.measure(childWidthSpec, childHeightSpec);
measuredDimension[0] = view.getMeasuredWidth() + p.leftMargin + p.rightMargin;
measuredDimension[1] = view.getMeasuredHeight() + p.bottomMargin + p.topMargin;
recycler.recycleView(view);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
You could use use max
and min
with dict.get
:
maximum = max(mydict, key=mydict.get) # Just use 'min' instead of 'max' for minimum.
print(maximum, mydict[maximum])
# D 87
I had a similar problem. My solution was to switch off the antivirus software (Avast), download the .iso file, mount it (double click in the Windows Explorer on the .iso file), and then run it from the PowerShell with admin rights with the following switches:
.\vs_community.exe /NoWeb /NoRefresh
This way you don't have to go offline or remove your existing installation.
With version 1.2.0-alpha06 of material design library, now we can use android:background="..."
on MaterialButton
components:
<com.google.android.material.button.MaterialButton
android:background="#fff"
...
/>
You can keep primitive type by setting default value, in the your case just add "required = false" property:
@RequestParam(value = "i", required = false, defaultValue = "10") int i

You have to correctly override method equals() from class Object
Edit: I think that my first response was misunderstood probably because I was not too precise. So I decided to to add more explanations.
Why do you have to override equals()? Well, because this is in the domain of a developer to decide what does it mean for two objects to be equal. Reference equality is not enough for most of the cases.
For example, imagine that you have a HashMap whose keys are of type Person. Each person has name and address. Now, you want to find detailed bean using the key. The problem is, that you usually are not able to create an instance with the same reference as the one in the map. What you do is to create another instance of class Person. Clearly, operator == will not work here and you have to use equals().
But now, we come to another problem. Let's imagine that your collection is very large and you want to execute a search. The naive implementation would compare your key object with every instance in a map using equals(). That, however, would be very expansive. And here comes the hashCode(). As others pointed out, hashcode is a single number that does not have to be unique. The important requirement is that whenever equals() gives true for two objects, hashCode() must return the same value for both of them. The inverse implication does not hold, which is a good thing, because hashcode separates our keys into kind of buckets. We have a small number of instances of class Person in a single bucket. When we execute a search, the algorithm can jump right away to a correct bucket and only now execute equals for each instance. The implementation for hashCode() therefore must distribute objects as evenly as possible across buckets.
There is one more point. Some collections require a proper implementation of a hashCode() method in classes that are used as keys not only for performance reasons. The examples are: HashSet and LinkedHashSet. If they don’t override hashCode(), the default Object hashCode() method will allow multiple objects that you might consider "meaningfully equal" to be added to your "no duplicates allowed" set.
Some of the collections that use hashCode()
Have a look at those two classes from apache commons that will allow you to implement equals() and hashCode() easily
on Mac, how I usually solve it
Hope this helps OP or someone else reading
I am posting this as an answer because this is very important as of PHP 7.4.
The opcache.preload
mechanism of PHP 7.4 makes it possible to preload opcodes for classes. If you use it to preload a file that contains a class definition and some side effects, then classes defined in that file will "exist" for all subsequent scripts executed by this FPM server and its workers, but the side effects will not be in effect, and the autoloader will not require the file containing them because the class already "exists". This completely defeats any and all static initialization techniques that rely on executing top-level code in the file that contains the class definition.
you can solve it by overriding the Run function of CI_Form_Validation
copy this function in a class which extends CI_Form_Validation .
This function will override the parent class function . Here i added only a extra check which can handle file also
/**
* Run the Validator
*
* This function does all the work.
*
* @access public
* @return bool
*/
function run($group = '') {
// Do we even have any data to process? Mm?
if (count($_POST) == 0) {
return FALSE;
}
// Does the _field_data array containing the validation rules exist?
// If not, we look to see if they were assigned via a config file
if (count($this->_field_data) == 0) {
// No validation rules? We're done...
if (count($this->_config_rules) == 0) {
return FALSE;
}
// Is there a validation rule for the particular URI being accessed?
$uri = ($group == '') ? trim($this->CI->uri->ruri_string(), '/') : $group;
if ($uri != '' AND isset($this->_config_rules[$uri])) {
$this->set_rules($this->_config_rules[$uri]);
} else {
$this->set_rules($this->_config_rules);
}
// We're we able to set the rules correctly?
if (count($this->_field_data) == 0) {
log_message('debug', "Unable to find validation rules");
return FALSE;
}
}
// Load the language file containing error messages
$this->CI->lang->load('form_validation');
// Cycle through the rules for each field, match the
// corresponding $_POST or $_FILES item and test for errors
foreach ($this->_field_data as $field => $row) {
// Fetch the data from the corresponding $_POST or $_FILES array and cache it in the _field_data array.
// Depending on whether the field name is an array or a string will determine where we get it from.
if ($row['is_array'] == TRUE) {
if (isset($_FILES[$field])) {
$this->_field_data[$field]['postdata'] = $this->_reduce_array($_FILES, $row['keys']);
} else {
$this->_field_data[$field]['postdata'] = $this->_reduce_array($_POST, $row['keys']);
}
} else {
if (isset($_POST[$field]) AND $_POST[$field] != "") {
$this->_field_data[$field]['postdata'] = $_POST[$field];
} else if (isset($_FILES[$field]) AND $_FILES[$field] != "") {
$this->_field_data[$field]['postdata'] = $_FILES[$field];
}
}
$this->_execute($row, explode('|', $row['rules']), $this->_field_data[$field]['postdata']);
}
// Did we end up with any errors?
$total_errors = count($this->_error_array);
if ($total_errors > 0) {
$this->_safe_form_data = TRUE;
}
// Now we need to re-set the POST data with the new, processed data
$this->_reset_post_array();
// No errors, validation passes!
if ($total_errors == 0) {
return TRUE;
}
// Validation fails
return FALSE;
}
sudo find / | grep -i mysql
This worked like a charm for me. Just went through the list and ensured that anything MySQL related was deleted.
Do you want to iterate over characters or words?
For words, you'll have to split the words first, such as
for index, word in enumerate(loopme.split(" ")):
print "CURRENT WORD IS", word, "AT INDEX", index
This prints the index of the word.
For the absolute character position you'd need something like
chars = 0
for index, word in enumerate(loopme.split(" ")):
print "CURRENT WORD IS", word, "AT INDEX", index, "AND AT CHARACTER", chars
chars += len(word) + 1
I got this error because I forgot the type="module" inside the script tag:

I think you are a little messed up with what you doing. Athlete is an object, athlete has a name, i has a city where he lives. Athlete can dive.
public class Athlete {
private String name;
private String city;
public Athlete (String name, String city){
this.name = name;
this.city = city;
}
--create method dive, (i am not sure what exactly i has to do)
public void dive (){}
}
public class Main{
public static void main (String [] args){
String name = in.next(); //enter name from keyboad
String city = in.next(); //enter city form keybord
--create a new object athlete and pass paramenters name and city into the object
Athlete a = new Athlete (name, city);
}
}
I have created some handy code snippets that'll create overloaded constructors as well. You're welcome to use them: https://github.com/ejbeaty/Power-Snippets
For example: 'ctor2' would create a constructor with two arguments and allow you to tab through them one by one like this:
public MyClass(ArgType argName, ArgType argName)
{
}
Sometimes if the update application is abruptly stopped, then the lock remains stuck.
Then running
UPDATE DATABASECHANGELOGLOCK SET LOCKED=0, LOCKGRANTED=null, LOCKEDBY=null where ID=1;
against the database helps.
You may also need to replace LOCKED=0
with LOCKED=FALSE
.
Or you can simply drop the DATABASECHANGELOGLOCK
table, it will be recreated.

As Martin Thoma has said, you need to normally apply thresholding. But you can do this using simple vectorization which will run much faster than the for loop that is used in that answer.
The code below converts the pixels of an image into 0 (black) and 1 (white).
from PIL import Image
import numpy as np
import matplotlib.pyplot as plt
#Pixels higher than this will be 1. Otherwise 0.
THRESHOLD_VALUE = 200
#Load image and convert to greyscale
img = Image.open("photo.png")
img = img.convert("L")
imgData = np.asarray(img)
thresholdedData = (imgData > THRESHOLD_VALUE) * 1.0
plt.imshow(thresholdedData)
plt.show()

First you need an object
public class MyObject {
public string Id {get;set;}
public string Text {get;set;}
...
}
Then in here
using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {
using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
JavaScriptSerializer js = new JavaScriptSerializer();
var objText = reader.ReadToEnd();
MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
}
}
I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.
JavaScriptSerializer System.Web.Script.Serialization
call like this

I like using pandas.apply() with python format().
import pandas as pd
s = pd.Series([1.357, 1.489, 2.333333])
make_float = lambda x: "${:,.2f}".format(x)
s.apply(make_float)
Also, it can be easily used with multiple columns...
df = pd.concat([s, s * 2], axis=1)
make_floats = lambda row: "${:,.2f}, ${:,.3f}".format(row[0], row[1])
df.apply(make_floats, axis=1)
The child views in your list row should be considered selected whenever the parent row is selected, so you should be able to just set a normal state drawable/color-list on the views you want to change, no messy Java code necessary. See this SO post.
Specifically, you'd set the textColor
of your textViews to an XML resource like this one:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true" android:drawable="@color/black" /> <!-- focused -->
<item android:state_focused="true" android:state_pressed="true" android:drawable="@color/black" /> <!-- focused and pressed-->
<item android:state_pressed="true" android:drawable="@color/green" /> <!-- pressed -->
<item android:drawable="@color/black" /> <!-- default -->
</selector>
In phpMyAdmin, navigate to the table in question and click the "Operations" tab. On the left under Table Options you will be allowed to set the current AUTO_INCREMENT value.

One workaround is to create clone environment, and then remove original one:
(remember about deactivating current environment with deactivate
on Windows and source deactivate
on macOS/Linux)
conda create --name new_name --clone old_name
conda remove --name old_name --all # or its alias: `conda env remove --name old_name`

I think this need to be run from the Management Shell rather than the console, it sounds like the module isn't being imported into the Powershell console. You can add the module by running:
Add-PSSnapin Microsoft.Sharepoint.Powershell
in the Powershell console.
Take a look at Shell MegaPack control set. It provides Windows Explorer like folder/file browsing with most of the features and functionality like context menus, renaming, drag-drop, icons, overlay icons, thumbnails, etc
If your project is not a Gradle project,
And you got this "local path doesn't exist" error after updating Android Studio to 0.9.2+ version
You should open the .iml file of the project and remove this:

<configuration>
<option name="GRADLE_PROJECT_PATH" />
</configuration>
</facet>
It solved the problem for me.
Output from subprocess.call()
should only be redirected to files.
You should use subprocess.Popen()
instead. Then you can pass subprocess.PIPE
for the stderr, stdout, and/or stdin parameters and read from the pipes by using the communicate()
method:
from subprocess import Popen, PIPE
p = Popen(['program', 'arg1'], stdin=PIPE, stdout=PIPE, stderr=PIPE)
output, err = p.communicate(b"input data that is passed to subprocess' stdin")
rc = p.returncode
The reasoning is that the file-like object used by subprocess.call()
must have a real file descriptor, and thus implement the fileno()
method. Just using any file-like object won't do the trick.

Is it too late to go back and get the un-uppercased data?
The von Neumann's, McCain's, DeGuzman's, and the Johnson-Smith's of your client base may not like the result of your processing...
Also, I'm guessing that this is intended to be a one-time upgrade of the data? It might be easier to export, filter/modify, and re-import the corrected names into the db, and then you can use non-SQL approaches to name fixing...
You'll need pattern recognition for that. To determine small differences between two images, Hopfield nets work fairly well and are quite easy to implement. I don't know any available implementations, though.
Hi i wrote this general function to generate a dummy variable which essentially replicates the replace function in Stata.
If x is the data frame is x and i want a dummy variable called a
which will take value 1
when x$b
takes value c
introducedummy<-function(x,a,b,c){
g<-c(a,b,c)
n<-nrow(x)
newcol<-g[1]
p<-colnames(x)
p2<-c(p,newcol)
new1<-numeric(n)
state<-x[,g[2]]
interest<-g[3]
for(i in 1:n){
if(state[i]==interest){
new1[i]=1
}
else{
new1[i]=0
}
}
x$added<-new1
colnames(x)<-p2
x
}

A way i did it was to create a separate res folder at the same level as the actual res folder in your project, then you can use this in your apps build.gradle
android {
//other stuff
sourceSets {
main.res.srcDirs = ['src/main/res', file('src/main/layouts').listFiles()]
}
}
then each subfolder of your new res folder can be something relating to each particular screen or something in your app, and each folder will have their own layout
/ drawable
/ values
etc keeping things organised and you dont have to update the gradle file manually like some of these other answers require (Just sync your gradle each time you add a new resource folder so it knows about it, and make sure to add the relevant subfolders before adding your xml files).
The number of distinct words (i.e. count of entries in the dictionary) can be found using the len()
function.
> a = {'foo':42, 'bar':69}
> len(a)
2
To get all the distinct words (i.e. the keys), use the .keys()
method.
> list(a.keys())
['foo', 'bar']
You're giving parameters to your program instead to Java. Use
java -Dtest="true" -jar myApplication.jar
instead.
Consider using
"true".equalsIgnoreCase(System.getProperty("test"))
to avoid the NPE. But do not use "Yoda conditions" always without thinking, sometimes throwing the NPE is the right behavior and sometimes something like
System.getProperty("test") == null || System.getProperty("test").equalsIgnoreCase("true")
is right (providing default true). A shorter possibility is
!"false".equalsIgnoreCase(System.getProperty("test"))
but not using double negation doesn't make it less hard to misunderstand.
Here is a method that I found long ago and cleaned up a bit. This works great, and can be quickly changed to accept objects as well.
/**
* A method for sorting arrays by a certain key:value.
* SortByKey is the key you wish to sort by
* Direction can be ASC or DESC.
*
* @param $array
* @param $sortByKey
* @param $sortDirection
* @return array
*/
private function sortArray($array, $sortByKey, $sortDirection) {
$sortArray = array();
$tempArray = array();
foreach ( $array as $key => $value ) {
$tempArray[] = strtolower( $value[ $sortByKey ] );
}
if($sortDirection=='ASC'){ asort($tempArray ); }
else{ arsort($tempArray ); }
foreach ( $tempArray as $key => $temp ){
$sortArray[] = $array[ $key ];
}
return $sortArray;
}
to change the method to sort objects simply change the following line:
$tempArray[] = strtolower( $value[ $sortByKey ] );
to
$tempArray[] = strtolower( $value->$sortByKey );
To run the method simply do
sortArray($inventory,'price','ASC');
jQuery provides a way to encode and decode html entities.
If you use a "<div/>" tag, it will strip out all the html.
function htmlDecode(value) {
return $("<div/>").html(value).text();
}
function htmlEncode(value) {
return $('<div/>').text(value).html();
}
If you use a "<textarea/>" tag, it will preserve the html tags.
function htmlDecode(value) {
return $("<textarea/>").html(value).text();
}
function htmlEncode(value) {
return $('<textarea/>').text(value).html();
}
Old question, I know. Disabling the cache facility is not needed and not the best way to manage the problem. By disabling the cache facility the server needs to work harder and generates more traffic. Also the browser and device needs to work harder, especially on mobile devices this could be a problem.
The empty page can be easily solved by using Shift key+reload button at the browser.
The empty page can be a result of:
Try first the Shift keyboard key + reload button and see if the problem still exists and review your code.
Look at where your html file is, the path you provided is relative not absolute. Are you sure it's placed correctly. According to the path you gave in the example above: "src="../js/moment.js" " the JS file is one level higher in hierarchy. So it should be placed as following:
Parent folder sub-folder html file js (this is a folder) moment.js
The double dots means the parent folder from current directory, in your case, the current directory is the location of html file.
But to make your life easier using a server will safe you troubles of doing this manually since the server directory is same all time so it's much easier.
New in python 3.8, you can pass a delimiter argument to the hex
function, as in this example
>>> value = b'\xf0\xf1\xf2'
>>> value.hex('-')
'f0-f1-f2'
>>> value.hex('_', 2)
'f0_f1f2'
>>> b'UUDDLRLRAB'.hex(' ', -4)
'55554444 4c524c52 4142'
To delete every branch except the one that you currently have checked out:
for b in `git branch --merged | grep -v \*`; do git branch -D $b; done
I would recommend changing git branch -D $b
to an echo $b
the first few times to make sure that it deletes the branches that you intend.

Same as the updating existing collection field, $set
will add a new fields if the specified field does not exist.
Check out this example:
> db.foo.find()
> db.foo.insert({"test":"a"})
> db.foo.find()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "test" : "a" }
> item = db.foo.findOne()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "test" : "a" }
> db.foo.update({"_id" :ObjectId("4e93037bbf6f1dd3a0a9541a") },{$set : {"new_field":1}})
> db.foo.find()
{ "_id" : ObjectId("4e93037bbf6f1dd3a0a9541a"), "new_field" : 1, "test" : "a" }
EDIT:
In case you want to add a new_field to all your collection, you have to use empty selector, and set multi flag to true (last param) to update all the documents
db.your_collection.update(
{},
{ $set: {"new_field": 1} },
false,
true
)
EDIT:
In the above example last 2 fields false, true
specifies the upsert
and multi
flags.
Upsert: If set to true, creates a new document when no document matches the query criteria.
Multi: If set to true, updates multiple documents that meet the query criteria. If set to false, updates one document.
This is for Mongo versions
prior to 2.2
. For latest versions the query is changed a bit
db.your_collection.update({},
{$set : {"new_field":1}},
{upsert:false,
multi:true})
You have a library that needs to be erased Like the following library
implementation 'org.apache.maven.plugins:maven-surefire-plugin:2.4.3'
I use something like this
>>> import datetime
>>> regex = datetime.datetime.strptime
>>>
>>> # TEST
>>> assert regex('2020-08-03', '%Y-%m-%d')
>>>
>>> assert regex('2020-08', '%Y-%m-%d')
ValueError: time data '2020-08' does not match format '%Y-%m-%d'
>>> assert regex('08/03/20', '%m/%d/%y')
>>>
>>> assert regex('08-03-2020', '%m/%d/%y')
ValueError: time data '08-03-2020' does not match format '%m/%d/%y'
When passing parameters through the URL you're able to retrieve the values as GET parameters.
Use this:
$variable = $_GET['param_name'];
//Or as you have it
$ppc = $_GET['ppc'];
It is safer to check for the variable first though:
if (isset($_GET['ppc'])) {
$ppc = $_GET['ppc'];
} else {
//Handle the case where there is no parameter
}
Here's a bit of reading on GET/POST params you should look at: http://php.net/manual/en/reserved.variables.get.php
EDIT: I see this answer still gets a lot of traffic years after making it. Please read comments attached to this answer, especially input from @emc who details a WordPress function which accomplishes this goal securely.
If your choices are not pre-decided or they are coming from some other source, you can generate them in your view and pass it to the form .
Example:
views.py:
def my_view(request, interview_pk):
interview = Interview.objects.get(pk=interview_pk)
all_rounds = interview.round_set.order_by('created_at')
all_round_names = [rnd.name for rnd in all_rounds]
form = forms.AddRatingForRound(all_round_names)
return render(request, 'add_rating.html', {'form': form, 'interview': interview, 'rounds': all_rounds})
forms.py
class AddRatingForRound(forms.ModelForm):
def __init__(self, round_list, *args, **kwargs):
super(AddRatingForRound, self).__init__(*args, **kwargs)
self.fields['name'] = forms.ChoiceField(choices=tuple([(name, name) for name in round_list]))
class Meta:
model = models.RatingSheet
fields = ('name', )
template:
<form method="post">
{% csrf_token %}
{% if interview %}
{{ interview }}
{% endif %}
{% if rounds %}
<hr>
{{ form.as_p }}
<input type="submit" value="Submit" />
{% else %}
<h3>No rounds found</h3>
{% endif %}
</form>
One thing to keep in mind:
If you develop a webpage to be displayed within UIWebView on iOS, then you have to use BASE tag. It simply won't work otherwise. Be that JavaScript, CSS, images - none of them will work with relative links under UIWebView, unless tag BASE is specified.
I've been caught by this before, till I found out.
<style>
.abc {
text-align: center;
}
</style>
<table class="abc">
<tr>
<td>Item1</td>
<td>Item2</td>
</tr>
</table>
If you have an object that can be converted to {key: 'stringValue'}
pairs, you can use this shortcut to convert it:
this._Http.get(myUrlString, {params: {...myParamsObject}});
I just love the spread syntax!
I spent quite a while wrestling with this problem and then I realized I was making a simple mistake in the fact that I had forgotten which particular database I was targeting my connection to. I was using the standard SQL Server connection window to enter the credentials:
I had to check the Connection Properties tab to verify that I was choosing the correct database to connect to. I had accidentally left the Connect to database option here set to a selection from a previous session. This is why I was unable to connect to the database I thought I was trying to connect to.
Note that you need to click the Options >>
button in order for the Connection Properties and other tabs to show up.
You're trying to use a dict
as a key to another dict
or in a set
. That does not work because the keys have to be hashable. As a general rule, only immutable objects (strings, integers, floats, frozensets, tuples of immutables) are hashable (though exceptions are possible). So this does not work:
>>> dict_key = {"a": "b"}
>>> some_dict[dict_key] = True
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'
To use a dict as a key you need to turn it into something that may be hashed first. If the dict you wish to use as key consists of only immutable values, you can create a hashable representation of it like this:
>>> key = frozenset(dict_key.items())
Now you may use key
as a key in a dict
or set
:
>>> some_dict[key] = True
>>> some_dict
{frozenset([('a', 'b')]): True}
Of course you need to repeat the exercise whenever you want to look up something using a dict:
>>> some_dict[dict_key] # Doesn't work
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'
>>> some_dict[frozenset(dict_key.items())] # Works
True
If the dict
you wish to use as key has values that are themselves dicts and/or lists, you need to recursively "freeze" the prospective key. Here's a starting point:
def freeze(d):
if isinstance(d, dict):
return frozenset((key, freeze(value)) for key, value in d.items())
elif isinstance(d, list):
return tuple(freeze(value) for value in d)
return d
Identity is not equality.
==
test identity.equals(Object obj)
method compares equality test(i.e. we need to tell equality by overriding the method)Why do I need to override the equals and hashCode methods in Java?
First we have to understand the use of equals method.
In order to identity differences between two objects we need to override equals method.
For example:
Customer customer1=new Customer("peter");
Customer customer2=customer1;
customer1.equals(customer2); // returns true by JVM. i.e. both are refering same Object
------------------------------
Customer customer1=new Customer("peter");
Customer customer2=new Customer("peter");
customer1.equals(customer2); //return false by JVM i.e. we have two different peter customers.
------------------------------
Now I have overriden Customer class equals method as follows:
@Override
public boolean equals(Object obj) {
if (this == obj) // it checks references
return true;
if (obj == null) // checks null
return false;
if (getClass() != obj.getClass()) // both object are instances of same class or not
return false;
Customer other = (Customer) obj;
if (name == null) {
if (other.name != null)
return false;
} else if (!name.equals(other.name)) // it again using bulit in String object equals to identify the difference
return false;
return true;
}
Customer customer1=new Customer("peter");
Customer customer2=new Customer("peter");
Insteady identify the Object equality by JVM, we can do it by overring equals method.
customer1.equals(customer2); // returns true by our own logic
Now hashCode method can understand easily.
hashCode produces integer in order to store object in data structures like HashMap, HashSet.
Assume we have override equals method of Customer
as above,
customer1.equals(customer2); // returns true by our own logic
While working with data structure when we store object in buckets(bucket is a fancy name for folder). If we use built-in hash technique, for above two customers it generates two different hashcode. So we are storing the same identical object in two different places. To avoid this kind of issues we should override the hashCode method also based on the following principles.
I'll assume you want to check a string value. One nice way is the REGEXP operator, matching the string to a regular expression. Simply do
select field from table where field REGEXP '^-?[0-9]+$';
this is reasonably fast. If your field is numeric, just test for
ceil(field) = field
instead.
Inspired in this answer I came up with a bit more object-oriented solution.
This is only valid if you're intending to read characters
You can override BufferedReader and implement something like this:
public class SafeBufferedReader extends BufferedReader{
private long millisTimeout;
( . . . )
@Override
public int read(char[] cbuf, int off, int len) throws IOException {
try {
waitReady();
} catch(IllegalThreadStateException e) {
return 0;
}
return super.read(cbuf, off, len);
}
protected void waitReady() throws IllegalThreadStateException, IOException {
if(ready()) return;
long timeout = System.currentTimeMillis() + millisTimeout;
while(System.currentTimeMillis() < timeout) {
if(ready()) return;
try {
Thread.sleep(100);
} catch (InterruptedException e) {
break; // Should restore flag
}
}
if(ready()) return; // Just in case.
throw new IllegalThreadStateException("Read timed out");
}
}
Here's an almost complete example.
I'm returning 0 on some methods, you should change it to -2 to meet your needs, but I think that 0 is more suitable with BufferedReader contract. Nothing wrong happened, it just read 0 chars. readLine method is a horrible performance killer. You should create a entirely new BufferedReader if you actually want to use readLine. Right now, it is not thread safe. If someone invokes an operation while readLines is waiting for a line, it will produce unexpected results
I don't like returning -2 where I am. I'd throw an exception because some people may just be checking if int < 0 to consider EOS. Anyway, those methods claim that "can't block", you should check if that statement is actually true and just don't override'em.

Although not technically grep nor command line, both Microsoft Visual Studio and Notepad++ have a very good Find in Files feature with full regular expression support. I find myself using them frequently even though I also have the CygWin version of grep available on the command line.
JavaScript is single threaded and has a synchronous execution model. Single threaded means that one command is being executed at a time. Synchronous means one at a time i.e. one line of code is being executed at time in order the code appears. So in JavaScript one thing is happening at a time.
Execution Context
The JavaScript engine interacts with other engines in the browser. In the JavaScript execution stack there is global context at the bottom and then when we invoke functions the JavaScript engine creates new execution contexts for respective functions. When the called function exits its execution context is popped from the stack, and then next execution context is popped and so on...
For example
function abc()
{
console.log('abc');
}
function xyz()
{
abc()
console.log('xyz');
}
var one = 1;
xyz();
In the above code a global execution context will be created and in this context var one
will be stored and its value will be 1... when the xyz() invocation is called then a new execution context will be created and if we had defined any variable in xyz function those variables would be stored in the execution context of xyz(). In the xyz function we invoke abc() and then the abc() execution context is created and put on the execution stack... Now when abc() finishes its context is popped from stack, then the xyz() context is popped from stack and then global context will be popped...
Now about asynchronous callbacks; asynchronous means more than one at a time.
Just like the execution stack there is the Event Queue. When we want to be notified about some event in the JavaScript engine we can listen to that event, and that event is placed on the queue. For example an Ajax request event, or HTTP request event.
Whenever the execution stack is empty, like shown in above code example, the JavaScript engine periodically looks at the event queue and sees if there is any event to be notified about. For example in the queue there were two events, an ajax request and a HTTP request. It also looks to see if there is a function which needs to be run on that event trigger... So the JavaScript engine is notified about the event and knows the respective function to execute on that event... So the JavaScript engine invokes the handler function, in the example case, e.g. AjaxHandler() will be invoked and like always when a function is invoked its execution context is placed on the execution context and now the function execution finishes and the event ajax request is also removed from the event queue... When AjaxHandler() finishes the execution stack is empty so the engine again looks at the event queue and runs the event handler function of HTTP request which was next in queue. It is important to remember that the event queue is processed only when execution stack is empty.
For example see the code below explaining the execution stack and event queue handling by Javascript engine.
function waitfunction() {
var a = 5000 + new Date().getTime();
while (new Date() < a){}
console.log('waitfunction() context will be popped after this line');
}
function clickHandler() {
console.log('click event handler...');
}
document.addEventListener('click', clickHandler);
waitfunction(); //a new context for this function is created and placed on the execution stack
console.log('global context will be popped after this line');
And
<html>
<head>
</head>
<body>
<script src="program.js"></script>
</body>
</html>
Now run the webpage and click on the page, and see the output on console. The output will be
waitfunction() context will be popped after this line
global context will be emptied after this line
click event handler...
The JavaScript engine is running the code synchronously as explained in the execution context portion, the browser is asynchronously putting things in event queue. So the functions which take a very long time to complete can interrupt event handling. Things happening in a browser like events are handled this way by JavaScript, if there is a listener supposed to run, the engine will run it when the execution stack is empty. And events are processed in the order they happen, so the asynchronous part is about what is happening outside the engine i.e. what should the engine do when those outside events happen.
So JavaScript is always synchronous.
You may be using old version of Mysql but surely you can use
DELETE FROM konta WHERE taken <> ''
But there are many other options available. You can try the following ones
DELETE * from konta WHERE strcmp(taken, '') <> 0;
DELETE * from konta where NOT (taken = '');
Another reason of this problem may be a missing library.
Go to Properties -> Android and check that you add the libraries correctly
You can dump a whole database in one go with mysqldump's --tab
option. You supply a directory path and it creates one .sql
file with the CREATE TABLE DROP IF EXISTS
syntax and a .txt
file with the contents, tab separated. To create comma separated files you could use the following:
mysqldump --password --fields-optionally-enclosed-by='"' --fields-terminated-by=',' --tab /tmp/path_to_dump/ database_name
That path needs to be writable by both the mysql user and the user running the command, so for simplicity I recommend chmod 777 /tmp/path_to_dump/
first.

git stash pop
applies the top stashed element and removes it from the stack. git stash apply
does the same, but leaves it in the stash stack.
I think I have found an easy hack out.
Delete the file that you have on the local repository (the file that you want updated from the latest commit in the remote server)
And then do a git pull
Because the file is deleted, there will be no conflict
Using PHP close/open tags is not very good solution because of 2 reasons: you can't print PHP variables in plain HTML and it make your code very hard to read (the next code block starts with an end bracket }
, but the reader has no idea what was before).
Better is to use heredoc syntax. It is the same concept as in other languages (like bash).
<?php
if ($condition) {
echo <<< END_OF_TEXT
<b>lots of html</b> <i>$variable</i>
lots of text...
many lines possible, with any indentation, until the closing delimiter...
END_OF_TEXT;
}
?>
END_OF_TEXT
is your delimiter (it can be basically any text like EOF, EOT). Everything between is considered string by PHP as if it were in double quotes, so you can print variables, but you don't have to escape any quotes, so it very convenient for printing html attributes.
Note that the closing delimiter must begin on the start of the line and semicolon must be placed right after it with no other chars (END_OF_TEXT;
).
Heredoc with behaviour of string in single quotes ('
) is called nowdoc. No parsing is done inside of nowdoc. You use it in the same way as heredoc, just you put the opening delimiter in single quotes - echo <<< 'END_OF_TEXT'
.
This command is working fine for me ubuntu 16.04 LTS:
npm install --save-dev @angular/cli@latest
Honestly.. you are going about this the wrong way by relying on inject to mock a service instead of module. Also, calling inject in a beforeEach is an anti-pattern as it makes mocking difficult on a per test basis.
Here is how I would do this...
module(function ($provide) {
// By using a decorator we can access $q and stub our method with a promise.
$provide.decorator('myOtherService', function ($delegate, $q) {
$delegate.makeRemoteCallReturningPromise = function () {
var dfd = $q.defer();
dfd.resolve('some value');
return dfd.promise;
};
});
});
Now when you inject your service it will have a properly mocked method for usage.
Wikipedia's explanation is:
Typically, quicksort is significantly faster in practice than other T(nlogn) algorithms, because its inner loop can be efficiently implemented on most architectures, and in most real-world data it is possible to make design choices which minimize the probability of requiring quadratic time.
I think there are also issues with the amount of storage needed for Mergesort (which is O(n)) that quicksort implementations don't have. In the worst case, they are the same amount of algorithmic time, but mergesort requires more storage.
For this sample the comprehension is fastest
$ python -m timeit -s 's=["one","two","three"]*1000' '[x.upper for x in s]' 1000 loops, best of 3: 809 usec per loop $ python -m timeit -s 's=["one","two","three"]*1000' 'map(str.upper,s)' 1000 loops, best of 3: 1.12 msec per loop $ python -m timeit -s 's=["one","two","three"]*1000' 'map(lambda x:x.upper(),s)' 1000 loops, best of 3: 1.77 msec per loop
You can use float:left in DIV or use SPAN tag, like
<div style="width:100px;float:left"> First </div>
<div> Second </div>
<br/>
or
<span style="width:100px;"> First </span>
<span> Second </span>
<br/>
Thread t1 = new Thread(new Runnable() {
@Override
public void run() {
// code goes here.
}
});
t1.start();
or
new Thread(new Runnable() {
@Override
public void run() {
// code goes here.
}
}).start();
or
new Thread(() -> {
// code goes here.
}).start();
or
Executors.newSingleThreadExecutor().execute(new Runnable() {
@Override
public void run() {
myCustomMethod();
}
});
or
Executors.newCachedThreadPool().execute(new Runnable() {
@Override
public void run() {
myCustomMethod();
}
});
In python
Using built in method
driver.refresh()
or, executing JavaScript
driver.execute_script("location.reload()")
The keyword you're looking for is list comprehensions:
>>> x = [1, 2, 3, 4, 5]
>>> y = [2*a for a in x if a % 2 == 1]
>>> print(y)
[2, 6, 10]
According to size_t description on en.cppreference.com size_t
is defined in the following headers :
std::size_t
...
Defined in header <cstddef>
Defined in header <cstdio>
Defined in header <cstring>
Defined in header <ctime>
Defined in header <cwchar>
1 += 2
is a syntax error (left-side must be a variable).
x += y
is shorthand for x = x + y

Follow the steps given below:
Stop your MySQL server completely. This can be done by accessing the Services window inside Windows XP and Windows Server 2003, where you can stop the MySQL service.
Open your MS-DOS command prompt using "cmd" inside the Run window. Inside it navigate to your MySQL bin folder, such as C:\MySQL\bin using the cd command.
Execute the following command in the command prompt: mysqld.exe -u root --skip-grant-tables
Leave the current MS-DOS command prompt as it is, and open a new MS-DOS command prompt window.
Navigate to your MySQL bin folder, such as C:\MySQL\bin using the cd command.
Enter mysql
and press enter.
You should now have the MySQL command prompt working. Type use mysql;
so that we switch to the "mysql" database.
Execute the following command to update the password:
UPDATE user SET Password = PASSWORD('NEW_PASSWORD') WHERE User = 'root';
However, you can now run any SQL command that you wish.
After you are finished close the first command prompt and type exit;
in the second command prompt windows to disconnect successfully. You can now start the MySQL service.
From the documentation:
In order to execute a command and have it not hang your PHP script while
it runs, the program you run must not output back to PHP. To do this,
redirect both stdout and stderr to /dev/null, then background it.
> /dev/null 2>&1 &
In order to execute a command and have
it spawned off as another process that
is not dependent on the Apache thread
to keep running (will not die if
somebody cancels the page) run this:
exec('bash -c "exec nohup setsid your_command > /dev/null 2>&1 &"');
this is output of this program
Scanner s=new Scanner (System.in);
int row, elem, col;
Systm.out.println("Enter Element to insert");
elem = s.nextInt();
System.out.println("Enter row");
row=s.nextInt();
System.out.println("Enter row");
col=s.nextInt();
for (int c=row-1; c < row; c++)
{
for (d = col-1 ; d < col ; d++)
array[c][d] = elem;
}
for(c = 0; c < size; c++)
{
for (d = 0 ; d < size ; d++)
System.out.print( array[c] [d] +" ");
System.out.println();
}
I have seen instances where the remote became out of sync and needed to be updated. If a reset --hard
or a branch -D
fail to work, try
git pull origin
git reset --hard
I fixed such a problem by putting a div down the nav link
<div [ngClass]="{'nav-div': tab['active']}"></div>
and giving this css to it.
.nav-div {
width: inherit;
position: relative;
height: 8px;
background: white;
top: 4px
}
and nav link css as
.nav-link {
position: relative;
top: 8px;
&.active {
box-shadow: rgba(0, 0, 0, 0.3) 0 1px 4px -1px;
}
}
Hope this helps!
For example you can find any textView:
TextView textView = (TextView) ((Activity) context).findViewById(R.id.textView1);
I created a jQuery function in order to make this task a bit easier. Just add this to your JavaScript file:
$.fn.dialogButtons = function(name, state){
var buttons = $(this).next('div').find('button');
if(!name)return buttons;
return buttons.each(function(){
var text = $(this).text();
if(text==name && state=='disabled') {$(this).attr('disabled',true).addClass('ui-state-disabled');return this;}
if(text==name && state=='enabled') {$(this).attr('disabled',false).removeClass('ui-state-disabled');return this;}
if(text==name){return this;}
if(name=='disabled'){$(this).attr('disabled',true).addClass('ui-state-disabled');return buttons;}
if(name=='enabled'){$(this).attr('disabled',false).removeClass('ui-state-disabled');return buttons;}
});};
Disable button 'OK' on dialog with class 'dialog':
$('.dialog').dialogButtons('Ok', 'disabled');
Enable all buttons:
$('.dialog').dialogButtons('enabled');
Enable 'Close' button and change color:
$('.dialog').dialogButtons('Close', 'enabled').css('color','red');
I hope this helps.
Dynamic resources can only be used when property being set is on object which is derived from dependency object or freezable where as static resources can be used anywhere. You can abstract away entire control using static resources.
Static resources are used under following circumstances:
Dynamic resources:
Be careful, you can not modify the preflight. In addition, the browser (at least chrome) removes the "authorization" header ... this results in some problems that may arise according to the route design. For example, a preflight will never enter the passport route sheet since it does not have the header with the token.
In case you are designing a file with an implementation of the options method, you must define in the route file web.php one (or more than one) "trap" route so that the preflght (without header authorization) can resolve the request and Obtain the corresponding CORS headers. Because they can not return in a middleware 200 by default, they must add the headers on the original request.
Are you meaning?
data2 <- data1[good,]
With
data1[good]
you're selecting columns in a wrong way (using a logical vector of complete rows).
Consider that parameter pollutant
is not used; is it a column name that you want to extract? if so it should be something like
data2 <- data1[good, pollutant]
Furthermore consider that you have to rbind
the data.frame
s inside the for
loop, otherwise you get only the last data.frame (its completed.cases)
And last but not least, i'd prefer generating filenames eg with
id <- 1:322
paste0( directory, "/", gsub(" ", "0", sprintf("%3d",id)), ".csv")
A little modified chunk of ?sprintf
The string fmt
(in our case "%3d"
) contains normal characters, which are passed through to the output string, and also conversion specifications which operate on the arguments provided through ...
. The allowed conversion specifications start with a %
and end with one of the letters in the set aAdifeEgGosxX%
. These letters denote the following types:
d
: integerEg a more general example
sprintf("I am %10d years old", 25)
[1] "I am 25 years old"

You can use CSS Grid:
dl {
display: grid;
grid-template-columns: repeat(2, minmax(0, 1fr));
}
_x000D_
<dl>
<dt>Title 1</dt>
<dd>Description 1</dd>
<dt>Title 2</dt>
<dd>Description 2</dd>
<dt>Title 3</dt>
<dd>Description 3</dd>
<dt>Title 4</dt>
<dd>Description 4</dd>
<dt>Title 5</dt>
<dd>Description 5</dd>

Parameters are key-value pairs that can appear inside URL path, and start with a semicolon character (;
).
Query string appears after the path (if any) and starts with a question mark character (?
).
Both parameters and query string contain key-value pairs.
In a GET
request, parameters appear in the URL itself:
<scheme>://<username>:<password>@<host>:<port>/<path>;<parameters>?<query>#<fragment>
In a POST
request, parameters can appear in the URL itself, but also in the datastream (as known as content).
Query string is always a part of the URL.
Parameters can be buried in form-data
datastream when using POST method so they may not appear in the URL. Yes a POST
request can define parameters as form data and in the URL, and this is not inconsistent because parameters can have several values.
I've found no explaination for this behavior so far. I guess it might be useful sometimes to "unhide" parameters from a POST
request, or even let the code handling a GET
request share some parts with the code handling a POST
. Of course this can work only with server code supporting parameters in a URL.
Until you get better insights, I suggest you to use parameters only in form-data
datastream of POST
requests.

You can develop your own thing in a second. For instance:
class Program
{
static void Main(string[] args)
{
var a = new object();
var b = new object();
Console.WriteLine("", a.GetId(), b.GetId());
}
}
public static class MyExtensions
{
//this dictionary should use weak key references
static Dictionary<object, int> d = new Dictionary<object,int>();
static int gid = 0;
public static int GetId(this object o)
{
if (d.ContainsKey(o)) return d[o];
return d[o] = gid++;
}
}
You can choose what you will like to have as unique ID on your own, for instance, System.Guid.NewGuid() or simply integer for fastest access.
You need to turn off the compiler optimisation.
If you are interested in a particular variable in gdb, you can delare the variable as "volatile" and recompile the code. This will make the compiler turn off compiler optimization for that variable.
volatile int quantity = 0;
you should use extend()
>>> c=[1,2,3]
>>> c.extend(c)
>>> c
[1, 2, 3, 1, 2, 3]
other info: append vs. extend
You can simply do this with help of AJAX... Here is a example which calls a python function which prints hello without redirecting or refreshing the page.
In app.py put below code segment.
#rendering the HTML page which has the button
@app.route('/json')
def json():
return render_template('json.html')
#background process happening without any refreshing
@app.route('/background_process_test')
def background_process_test():
print ("Hello")
return ("nothing")
And your json.html page should look like below.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type=text/javascript>
$(function() {
$('a#test').on('click', function(e) {
e.preventDefault()
$.getJSON('/background_process_test',
function(data) {
//do nothing
});
return false;
});
});
</script>
//button
<div class='container'>
<h3>Test</h3>
<form>
<a href=# id=test><button class='btn btn-default'>Test</button></a>
</form>
</div>
Here when you press the button Test simple in the console you can see "Hello" is displaying without any refreshing.
You should be using the strict not equals
comparison operator !==
so that if the user inputs "null"
then you won't get to the else
.
This is how it can be done using CASE
:
DECLARE @myParam INT;
SET @myParam = 1;
SELECT *
FROM MyTable
WHERE 'T' = CASE @myParam
WHEN 1 THEN
CASE WHEN MyColumn IS NULL THEN 'T' END
WHEN 2 THEN
CASE WHEN MyColumn IS NOT NULL THEN 'T' END
WHEN 3 THEN 'T' END;
To be specific, set the value to be the name of a constant of the enum type, e.g., "TYPE1" or "TYPE2" in your case, as shown below. And it will work:
<bean name="someName" class="my.pkg.classes">
<property name="type" value="TYPE1" />
</bean>
I just changed the .htaccess file contents and as shown in the following links answer. And tried refreshing the page (which didn't work, and couldn't find the request to my controller) it worked.
Then just because of my doubt I undone the changes I did to my .htaccess inside my public_html folder back to original .htaccess content. So it's now as follows (which is originally it was):
DirectoryIndex index.php
RewriteEngine on
RewriteCond $1 !^(index\.php|images|css|js|robots\.txt|favicon\.ico)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ ./index.php?/$1 [L,QSA]
And now also it works.
Hint: Seems like before the Rewrite Rules haven't been clearly setup within the Server context.
My file structure is as follows:
/
|- gheapp
| |- application
| L- system
|
|- public_html
| |- .htaccess
| L- index.php
And in the index.php
I have set up the following paths to the system and the application:
$system_path = '../gheapp/system';
$application_folder = '../gheapp/application';
Note: by doing so, our application source code becomes hidden to the public at first.
Please, if you guys find anything wrong with my answer, comment and re-correct me!
Hope beginners would find this answer helpful.
Thanks!
There are a number of ways to get information on the attributes of your DataFrame or Series.
Create Sample DataFrame and Series
df = pd.DataFrame({'a':[5, 2, np.nan], 'b':[ 9, 2, 4]})
df
a b
0 5.0 9
1 2.0 2
2 NaN 4
s = df['a']
s
0 5.0
1 2.0
2 NaN
Name: a, dtype: float64
shape
AttributeThe shape
attribute returns a two-item tuple of the number of rows and the number of columns in the DataFrame. For a Series, it returns a one-item tuple.
df.shape
(3, 2)
s.shape
(3,)
len
functionTo get the number of rows of a DataFrame or get the length of a Series, use the len
function. An integer will be returned.
len(df)
3
len(s)
3
size
attributeTo get the total number of elements in the DataFrame or Series, use the size
attribute. For DataFrames, this is the product of the number of rows and the number of columns. For a Series, this will be equivalent to the len
function:
df.size
6
s.size
3
ndim
attributeThe ndim
attribute returns the number of dimensions of your DataFrame or Series. It will always be 2 for DataFrames and 1 for Series:
df.ndim
2
s.ndim
1
count
methodThe count
method can be used to return the number of non-missing values for each column/row of the DataFrame. This can be very confusing, because most people normally think of count as just the length of each row, which it is not. When called on a DataFrame, a Series is returned with the column names in the index and the number of non-missing values as the values.
df.count() # by default, get the count of each column
a 2
b 3
dtype: int64
df.count(axis='columns') # change direction to get count of each row
0 2
1 2
2 1
dtype: int64
For a Series, there is only one axis for computation and so it just returns a scalar:
s.count()
2
info
method for retrieving metadataThe info
method returns the number of non-missing values and data types of each column
df.info()
<class 'pandas.core.frame.DataFrame'>
RangeIndex: 3 entries, 0 to 2
Data columns (total 2 columns):
a 2 non-null float64
b 3 non-null int64
dtypes: float64(1), int64(1)
memory usage: 128.0 bytes
When writing queries, this difference should be kept in mind :
DECLARE @A INT = 2
SELECT @A = TBL.A
FROM ( SELECT 1 A ) TBL
WHERE 1 = 2
SELECT @A
/* @A is 2*/
---------------------------------------------------------------
DECLARE @A INT = 2
SET @A = (
SELECT TBL.A
FROM ( SELECT 1 A) TBL
WHERE 1 = 2
)
SELECT @A
/* @A is null*/
