This code counts rows with date range:
Controller:
$this->load->model("YourModelName");
$data ['query'] = $this->YourModelName->get_report();
Model:
public function get_report()
{
$query = $this->db->query("SELECT *
FROM reservation WHERE arvdate <= '2016-7-20' AND dptrdate >= '2016-10-25' ");
return $query;
}
where 'arvdate' and 'dptrdate' are two dates on database and 'reservation' is the table name.
View:
<?php
echo $query->num_rows();
?>
This code is to return number of rows. To return table data, then use
$query->rows();
return $row->table_column_name;
If you want to see the changes including the # of lines that changed between your branch and another branch,
git diff the_other_branch_name --stat
This should work
gsub('\u009c','','\u009cYes yes for ever for ever the boys ')
"Yes yes for ever for ever the boys "
Here 009c is the hexadecimal number of unicode. You must always specify 4 hexadecimal digits. If you have many , one solution is to separate them by a pipe:
gsub('\u009c|\u00F0','','\u009cYes yes \u00F0for ever for ever the boys and the girls')
"Yes yes for ever for ever the boys and the girls"
Add**/.DS_Store
into .gitignore
for the sub directory
If .DS_Store
already committed:
find . -name .DS_Store -print0 | xargs -0 git rm --ignore-unmatch
To ignore them in all repository: (sometimes it named ._.DS_Store
)
echo ".DS_Store" >> ~/.gitignore_global
echo "._.DS_Store" >> ~/.gitignore_global
echo "**/.DS_Store" >> ~/.gitignore_global
echo "**/._.DS_Store" >> ~/.gitignore_global
git config --global core.excludesfile ~/.gitignore_global
I came up with this similar situation and I resolved it quiet easily.Here is what I did. Assuming you already have the value in array at your aspx.cs
page.
1)Put a hidden field in your aspx page and us the hidden field ID to store the array value.
HiddenField2.Value = string.Join(",", myarray);
2)Now that the hidden field has the value stored, just separated by commas. Use this hidden field in JavaScript like this. Simply create an array in JavaScript and then store the value in that array by removing the commas.
var hiddenfield2 = new Array();
hiddenfield2=document.getElementById('<%=HiddenField2.ClientID%>').value.split(',');
This should solve your problem.
If you mean that you have an environment variable named CLASSPATH, I'd say that's your mistake. I don't have such a thing on any machine with which I develop Java. CLASSPATH is so tied to a particular project that it's impossible to have a single, correct CLASSPATH that works for all.
I set CLASSPATH for each project using either an IDE or Ant. I do a lot of web development, so each WAR and EAR uses their own CLASSPATH.
It's ignored by IDEs and app servers. Why do you have it? I'd recommend deleting it.
i have been working on a dropdown replacement jquery plugin to combat this problem. As of this post, it is almost indistinguishable from a native dropdown in terms of look and functionality.
here is a demo (also a link to downloads): http://programmingdrunk.com/current-projects/dropdownReplacement/
here is the project page of the plugin:
http://plugins.jquery.com/project/dropdownreplacement
(update:) the jquery plugin page seems to no longer work. I will probably not put my plugin on their new site when they get it working, so feel free to use the programmingdrunk.com link for demo/download
This site says to try:
import datetime as dt
start="09:35:23"
end="10:23:00"
start_dt = dt.datetime.strptime(start, '%H:%M:%S')
end_dt = dt.datetime.strptime(end, '%H:%M:%S')
diff = (end_dt - start_dt)
diff.seconds/60
This forum uses time.mktime()
I don't know what you mean by "data dont get lost". Here's how you pass a normal 2D array to a function:
void myfunc(int arr[M][N]) { // M is optional, but N is required
..
}
int main() {
int somearr[M][N];
...
myfunc(somearr);
...
}
Note that if you use the xcodebuild
command line tool, then the last version of Xcode installed will become the default version. (A symbolic link is installed in /usr/bin.) To use the xcodebuild
for the other versions of Xcode you'll need to use the version in the (xcode_install_directory)/usr/bin
directory.
note To switch between different versions of the Xcode command-line tools, use the xcode-select
tool mentioned by other commenters.
You can use Javascript to get the viewport width and height. Then pass the values back via a hidden form input or ajax.
var width = $(window).width();
var height = $(window).height();
Assuming you have: JQuery framework.
First, add these hidden form inputs to store the width and height until postback.
<asp:HiddenField ID="width" runat="server" />
<asp:HiddenField ID="height" runat="server" />
Next we want to get the window (viewport) width and height. JQuery has two methods for this, aptly named width() and height().
Add the following code to your .aspx file within the head element.
<script type="text/javascript">
$(document).ready(function() {
$("#width").val() = $(window).width();
$("#height").val() = $(window).height();
});
</script>
Result
This will result in the width and height of the browser window being available on postback. Just access the hidden form inputs like this:
var TheBrowserWidth = width.Value;
var TheBrowserHeight = height.Value;
This method provides the height and width upon postback, but not on the intial page load.
Note on UpdatePanels: If you are posting back via UpdatePanels, I believe the hidden inputs need to be within the UpdatePanel.
Alternatively you can post back the values via an ajax call. This is useful if you want to react to window resizing.
Update for jquery 3.1.1
I had to change the JavaScript to:
$("#width").val($(window).width());
$("#height").val($(window).height());
loadXMLDoc JS function should return false, otherwise it will result in postback.
Usually you would be interested in also having some structure to your data in the receiving end:
json_encode($result)
This will preserve the array keys as well.
Do remember that json_encode only works on utf8 -encoded data.
You can try using this code:
protected ServiceConnection mServerConn = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName name, IBinder binder) {
Log.d(LOG_TAG, "onServiceConnected");
}
@Override
public void onServiceDisconnected(ComponentName name) {
Log.d(LOG_TAG, "onServiceDisconnected");
}
}
public void start() {
// mContext is defined upper in code, I think it is not necessary to explain what is it
mContext.bindService(intent, mServerConn, Context.BIND_AUTO_CREATE);
mContext.startService(intent);
}
public void stop() {
mContext.stopService(new Intent(mContext, ServiceRemote.class));
mContext.unbindService(mServerConn);
}
Google used to recommend putting it just before the </body>
tag, because the original method they provided for loading ga.js
was blocking. The newer async syntax, though, can safely be put in the head with minimal blockage, so the current recommendation is just before the </head>
tag.
<head>
will add a little latency; in the footer will reduce the number of pageviews recorded at some small margin. It's a tradeoff. ga.js
is heavily cached and present on a large percentage of sites across the web, so its often served from the cache, reducing latency to almost nil.
As a matter of personal preference, I like to include it in the <head>
, but its really a matter of preference.
For VS2017 and 2019... with the modern core library SDK project files, the platform can be changed during the build process. Here's an example to change to the anycpu
platform, just before the built-in CoreCompile
task runs:
<Project Sdk="Microsoft.NET.Sdk" >
<Target Name="SwitchToAnyCpu" BeforeTargets="CoreCompile" >
<Message Text="Current Platform=$(Platform)" />
<Message Text="Current PlatformTarget=$(PlatformName)" />
<PropertyGroup>
<Platform>anycpu</Platform>
<PlatformTarget>anycpu</PlatformTarget>
</PropertyGroup>
<Message Text="New Platform=$(Platform)" />
<Message Text="New PlatformTarget=$(PlatformTarget)" />
</Target>
</Project>
In my case, I'm building an FPGA with BeforeTargets
and AfterTargets
tasks, but compiling a C# app in the main CoreCompile
. (partly as I may want some sort of command-line app, and partly because I could not figure out how to omit or override CoreCompile
)
To build for multiple, concurrent binaries such as x86 and x64: either a separate, manual build task would be needed or two separate project files with the respective <PlatformTarget>x86</PlatformTarget>
and <PlatformTarget>x64</PlatformTarget>
settings in the example, above.
If you are using VS2010 or later it is even easier than that

Did you play around with setDefaultUncaughtExceptionHandler() and the alike methods of the Thread class? From the API: "By setting the default uncaught exception handler, an application can change the way in which uncaught exceptions are handled (such as logging to a specific device, or file) for those threads that would already accept whatever "default" behavior the system provided."
You might find the answer to your problem there... good luck! :-)
I uninstall Only Android studio (keep the SDK and Emulator) and then reinstall it just android studio. took me 2 minutes and my android studio work again.
Like this:
> df[df==""]<-NA
> df
A B
1 <NA> 12
2 xyz <NA>
3 jkl 100
The key is to keep the declarations of the variable in the header file and source file the same.
I use this trick
------sample.c------
#define sample_c
#include sample.h
(rest of sample .c)
------sample.h------
#ifdef sample_c
#define EXTERN
#else
#define EXTERN extern
#endif
EXTERN int x;
Sample.c is only compiled once and it defines the variables. Any file that includes sample.h is only given the "extern" of the variable; it does allocate space for that variable.
When you change the type of x, it will change for everybody. You won't need to remember to change it in the source file and the header file.
You can use the <input>
tag with attribute type='number'.
For example you can use <input type='number' />
This input field allows only numerical values. You can also specify the minimum value and maximum value that should be accepted by this field.
Why do people always use jQuery when it isn't necessary?
Why can't people just use simple JavaScript?
var ele = /*Your Form Element*/;
if(ele.addEventListener){
ele.addEventListener("submit", callback, false); //Modern browsers
}else if(ele.attachEvent){
ele.attachEvent('onsubmit', callback); //Old IE
}
callback
is a function that you want to call when the form is being submitted.
About EventTarget.addEventListener
, check out this documentation on MDN.
To cancel the native submit
event (prevent the form from being submitted), use .preventDefault()
in your callback function,
document.querySelector("#myForm").addEventListener("submit", function(e){
if(!isValid){
e.preventDefault(); //stop form from submitting
}
});
submit
event with librariesIf for some reason that you've decided a library is necessary (you're already using one or you don't want to deal with cross-browser issues), here's a list of ways to listen to the submit event in common libraries:
jQuery
$(ele).submit(callback);
Where ele
is the form element reference, and callback
being the callback function reference. Reference
<iframe width="100%" height="100%" src="http://jsfiddle.net/DerekL/wnbo1hq0/show" frameborder="0"></iframe>
_x000D_
AngularJS (1.x)
<form ng-submit="callback()">
$scope.callback = function(){ /*...*/ };
Very straightforward, where $scope
is the scope provided by the framework inside your controller. Reference
React
<form onSubmit={this.handleSubmit}>
class YourComponent extends Component {
// stuff
handleSubmit(event) {
// do whatever you need here
// if you need to stop the submit event and
// perform/dispatch your own actions
event.preventDefault();
}
// more stuff
}
Simply pass in a handler to the onSubmit
prop. Reference
Other frameworks/libraries
Refer to the documentation of your framework.
You can always do your validation in JavaScript, but with HTML5 we also have native validation.
<!-- Must be a 5 digit number -->
<input type="number" required pattern="\d{5}">
You don't even need any JavaScript! Whenever native validation is not supported, you can fallback to a JavaScript validator.
Actually python will reclaim the memory which is not in use anymore.This is called garbage collection which is automatic process in python. But still if you want to do it then you can delete it by del variable_name
. You can also do it by assigning the variable to None
a = 10
print a
del a
print a ## throws an error here because it's been deleted already.
The only way to truly reclaim memory from unreferenced Python objects is via the garbage collector. The del keyword simply unbinds a name from an object, but the object still needs to be garbage collected. You can force garbage collector to run using the gc module, but this is almost certainly a premature optimization but it has its own risks. Using del
has no real effect, since those names would have been deleted as they went out of scope anyway.
My simple and easy version to the problem:
function titlecase(str){
var arr=[];
var str1=str.split(' ');
for (var i = 0; i < str1.length; i++) {
var upper= str1[i].charAt(0).toUpperCase()+ str1[i].substr(1);
arr.push(upper);
};
return arr.join(' ');
}
titlecase('my name is suryatapa roy');
There is no other way, I have to specify everything twice. First for the insert, second in the update case.
Wrong answer - see EDIT at the end
Let me build on Alex's answer.
To prevent the creation of a data object if it doesn't exists, I would better do:
$.fn.hasData = function(key) {
var $this = $(this);
return $.hasData($this) && typeof $this.data(key) !== 'undefined';
};
Then, where $this
has no data object created, $.hasData
returns false
and it will not execute $this.data(key)
.
EDIT: function $.hasData(element)
works only if the data was set using $.data(element, key, value)
, not element.data(key, value)
. Due to that, my answer is not correct.
I have to say if you are going to be linking to that area in the page... such as page.html#foo and Foo Title isn't a link you should be using:
<h1 id="foo">Foo Title</h1>
If you instead put an <a>
reference around it your headline will be influenced by an <a>
specific CSS within your site. It's just extra markup, and you shouldn't need it. I'd highly recommend placing an id on the headline, not only is it better formed, but it will allow you to either address that object in Javascript or CSS.
Just for contrast, I like using the object_id function as shown below. It's a bit easier to read, and you don't have to worry about sys.objects vs. sysobjects vs. sys.all_objects vs. sys.tables. Basic form:
IF object_id('MyTable') is not null
PRINT 'Present!'
ELSE
PRINT 'Not accounted for'
Of course this will show as "Present" if there is any object present with that name. If you want to check just tables, you'd need:
IF object_id('MyTable', 'U') is not null
PRINT 'Present!'
ELSE
PRINT 'Not accounted for'
It works for temp tables as well:
IF object_id('tempdb.dbo.#MyTable') is not null
PRINT 'Present!'
ELSE
PRINT 'Not accounted for'
Just a piece of advice. Instead of writing
for (int i=0; i=((Main.size())-1); i++) {
cout << Main[i] << '\n';
}
as suggested above, write a:
for (vector<double>::iterator it=Main.begin(); it!=Main.end(); it++) {
cout << *it << '\n';
}
to use iterators. If you have C++11
support, you can declare i
as auto i=Main.begin()
(just a handy shortcut though)
This avoids the nasty one-position-out-of-bound error caused by leaving out a -1
unintentionally.
If you're trying to do it in a Xamarin Forms PCL project, the above solutions using IsAssignableFrom
gives an error:
Error: 'Type' does not contain a definition for 'IsAssignableFrom' and no extension method 'IsAssignableFrom' accepting a first argument of type 'Type' could be found (are you missing a using directive or an assembly reference?)
because IsAssignableFrom
asks for a TypeInfo
object.
You can use the GetTypeInfo()
method from System.Reflection
:
typeof(BaseClass).GetTypeInfo().IsAssignableFrom(typeof(unknownType).GetTypeInfo())
Use this:
import boto3
s3 = boto3.client('s3')
bucket_name = "YOUR-BUCKET-NAME"
directory_name = "DIRECTORY/THAT/YOU/WANT/TO/CREATE" #it's name of your folders
s3.put_object(Bucket=bucket_name, Key=(directory_name+'/'))
There's no pretty way. You might be able to use a proxy with the handler having the target methods and delegating everything else to them. Of course you'll have to use a factory because there'll be no constructor.

If you have to disable SSL checks for one git server hosting several repositories, you can run :
git config --bool --add http.https://my.bad.server.sslverify false
This will add it to your user's configuration.
Command to check:
git config --bool --get-urlmatch http.sslverify https://my.bad.server
(If you still use git < v1.8.5, run git config --global http.https://my.bad.server.sslVerify false
)
Explanation from the documentation where the command is at the end, show the
.gitconfig
content looking like:
[http "https://my.bad.server"]
sslVerify = false
It will ignore any certificate checks for this server, whatever the repository.
You also have some explanation in the code

Accepted answer throws a java.lang.StackOverflowError
when calling the setParent
or addChild
methods.
Here's a slightly simpler implementation without those bugs:
public class MyTreeNode<T>{
private T data = null;
private List<MyTreeNode> children = new ArrayList<>();
private MyTreeNode parent = null;
public MyTreeNode(T data) {
this.data = data;
}
public void addChild(MyTreeNode child) {
child.setParent(this);
this.children.add(child);
}
public void addChild(T data) {
MyTreeNode<T> newChild = new MyTreeNode<>(data);
this.addChild(newChild);
}
public void addChildren(List<MyTreeNode> children) {
for(MyTreeNode t : children) {
t.setParent(this);
}
this.children.addAll(children);
}
public List<MyTreeNode> getChildren() {
return children;
}
public T getData() {
return data;
}
public void setData(T data) {
this.data = data;
}
private void setParent(MyTreeNode parent) {
this.parent = parent;
}
public MyTreeNode getParent() {
return parent;
}
}
Some examples:
MyTreeNode<String> root = new MyTreeNode<>("Root");
MyTreeNode<String> child1 = new MyTreeNode<>("Child1");
child1.addChild("Grandchild1");
child1.addChild("Grandchild2");
MyTreeNode<String> child2 = new MyTreeNode<>("Child2");
child2.addChild("Grandchild3");
root.addChild(child1);
root.addChild(child2);
root.addChild("Child3");
root.addChildren(Arrays.asList(
new MyTreeNode<>("Child4"),
new MyTreeNode<>("Child5"),
new MyTreeNode<>("Child6")
));
for(MyTreeNode node : root.getChildren()) {
System.out.println(node.getData());
}

I found this question because I wanted to do the same as the OP. I would like to add the following observation:
The iterative way (user225312, Sven Marnach):
list2 = [x for x in list1 if x]
Will return a list
object in python3
and python2
. Instead the filter way (lunaryorn, Imran) will differently behave over versions:
list2 = filter(None, list1)
It will return a filter
object in python3
and a list
in python2
(see this question found at the same time). This is a slight difference but it must be take in account when developing compatible scripts.
This does not make any assumption about performances of those solutions. Anyway the filter object can be reverted to a list using:
list3 = list(list2)
I think it's too late to talk about API 21, but I found a easy way.
When using 'Custom Notification(custom layout)'s,
RemoteView's
setImageViewResource(int viewId, int srcId);
and
setImageViewUri(int viewId, Uri uri);
makes those image white on Lollipop (API 21).
But when using
setImageViewBitmap(int viewId, Bitmap bitmap);
Image doesn't become white-masked!

If you have the connectivity between servers it is better to set up replication (which is trivial, unlike with SQL) with the new instance as a slave node - then you can switch the new node to master with a single command and do the move with zero downtime.
I was trying Viachaslau's answer since I like the idea of not removing the button but disabling it, but for some reason it did not always work: the close button was still enabled but no errors whatsoever.
This on the other hand always worked (error checking omitted):
[DllImport( "user32.dll" )]
private static extern IntPtr GetSystemMenu( IntPtr hWnd, bool bRevert );
[DllImport( "user32.dll" )]
private static extern bool EnableMenuItem( IntPtr hMenu, uint uIDEnableItem, uint uEnable );
private const uint MF_BYCOMMAND = 0x00000000;
private const uint MF_GRAYED = 0x00000001;
private const uint SC_CLOSE = 0xF060;
private const int WM_SHOWWINDOW = 0x00000018;
protected override void OnSourceInitialized( EventArgs e )
{
base.OnSourceInitialized( e );
var hWnd = new WindowInteropHelper( this );
var sysMenu = GetSystemMenu( hWnd.Handle, false );
EnableMenuItem( sysMenu, SC_CLOSE, MF_BYCOMMAND | MF_GRAYED );
}
Also, if your service is sending an object instead of an array add isArray:false to its declaration.
'query': {method: 'GET', isArray: false }

Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
String aNameFromContacts[] = new String[contacts.getCount()];
String aNumberFromContacts[] = new String[contacts.getCount()];
int i = 0;
int nameFieldColumnIndex = contacts.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int numberFieldColumnIndex = contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

String contactName = contacts.getString(nameFieldColumnIndex);
aNameFromContacts[i] = contactName ;
String number = contacts.getString(numberFieldColumnIndex);
aNumberFromContacts[i] = number ;
i++;

All of the current answers are addressing the symptom (shared memory pool exhaustion), and not the problem, which is likely not using bind variables in your sql \ JDBC queries, even when it does not seem necessary to do so. Passing queries without bind variables causes Oracle to "hard parse" the query each time, determining its plan of execution, etc.

Some snippets from the above link:
"Java supports bind variables, your developers must start using prepared statements and bind inputs into it. If you want your system to ultimately scale beyond say about 3 or 4 users -- you will do this right now (fix the code). It is not something to think about, it is something you MUST do. A side effect of this - your shared pool problems will pretty much disappear. That is the root cause. "
"The way the Oracle shared pool (a very important shared memory data structure) operates is predicated on developers using bind variables."
" Bind variables are SO MASSIVELY important -- I cannot in any way shape or form OVERSTATE their importance. "
This error can also be caused by having zero methods tagged with the OperationContract attribute. This was my problem when building a new service and testing it a long the way.
Smarter:
for (String key : hashMap.keySet()) {
System.out.println("Key: " + key + ", Value: " + map.get(key));
}
I'm assuming the contents of src/main/resources/
is copied to WEB-INF/classes/
inside your .war at build time. If that is the case you can just do (substituting real values for the classname and the path being loaded).
URL sqlScriptUrl = MyServletContextListener.class
.getClassLoader().getResource("sql/script.sql");
If you already have python3 installed as well virtualenvwrapper the only thing you would need to do to use python3 with the virtual environment is creating an environment using:
which python3 #Output: /usr/bin/python3
mkvirtualenv --python=/usr/bin/python3 nameOfEnvironment
Or, (at least on OSX using brew):
mkvirtualenv --python=`which python3` nameOfEnvironment
Start using the environment and you'll see that as soon as you type python you'll start using python3
You can also use the root shortcut like so
<template>
<div class="container">
<h1>Recipes</h1>
<img src="@/assets/burger.jpg" />
</div>
</template>
Although this was Nuxt, it should be same with Vue CLI.
If the problem allows it, try with EXISTS, since it's optimized to end as soon as a result is found (And don't buffer any response), so, if you are just trying to normalize data for a WHERE clause like this
SELECT FROM SOMETHING S WHERE S.ID IN ( SELECT DISTINCT DCR.SOMETHING_ID FROM DIFF_CARDINALITY_RELATIONSHIP DCR ) -- to keep same cardinality
A faster response would be:
SELECT FROM SOMETHING S WHERE EXISTS ( SELECT 1 FROM DIFF_CARDINALITY_RELATIONSHIP DCR WHERE DCR.SOMETHING_ID = S.ID )
This isn't always possible but when available you will see a faster response.
It may not be the elegant way but you can iterate all classes in the assembly and invoke Type.IsSubclassOf(AbstractDataExport)
for each one.
TLDR; technically space sorts before exclamation mar, and can be used by preceding it with ' or - (which will be ignored in sorting), but exclamation mark follows right after space, and is easier to use.
On windows 7 at least, a minus sign (-) and (') seem to be ignored in a name except for one quirk: in a name that is otherwise identical, the ' will be sorted before -, for example: (a'a) will sort above (a-a)
Empty string will sort above everything else, which means for example aa will sort above aaa because the 'empty string' after two a letters will sort before the third 'a'.
This also means that aa will be sorted above a'a because the 'empty string' between two a letters will sort above the ' mark.
What follows then is, ' alone will sort first, because technically it's an empty string. However adding for example letters behind it will sort the name as if the ' didn't exist.
Since the first 'unignored' character (as far as I know) is space, in case you want to sort 'real names' above others, the best way to go would be ' followed by space, and then the name you want to actually use. For example: (' first)
You can of course top that by using more than one space in the strong, such as (' firster) and (' firstest) with two and three blanks before the f.
While minus sign sorts below ' in otherwise similar name, there's no other difference in sorting (that I know of), and I find minus sign visually clearer, so if I want to put something on top of list, I'd use minus followed by space, then the 'actual name', for example: (- first file -)
If you are worried about using space on the filename, then exclamation mark (!) is the next best thing - and since it can appear as first character on a string, it's easier to use.
use parseInt
var total = parseInt(a) + parseInt(b);
$('#total_price').val(total);
Another approach would be to have an array of objects, with each individual object holding the properties of a column. This slightly changes the structure of "myMappings", but makes it easy to work with:
var myMappings = [
{ title: "Name", width: "10%" },
{ title: "Phone", width: "10%" },
{ title: "Address", width: "50%" },
{ title: "Zip", width: "10%" },
{ title: "Comments", width: "20%" }
];
Then you could easily iterate through all your "columns" with a for loop:
for (var i = 0; i < myMappings.length; i += 1) {
// myMappings[i].title ...
// myMappings[i].width ...
}
If you are using iTerm this command will open a new tab:
osascript -e 'tell application "iTerm" to activate' -e 'tell application "System Events" to tell process "iTerm" to keystroke "t" using command down'
Simply we can trace the request message as.
OperationContext context = OperationContext.Current;
if (context != null && context.RequestContext != null)
{
Message msg = context.RequestContext.RequestMessage;
string reqXML = msg.ToString();
}
Use regex:
result = result.replaceAll("\n.*", "");
replaceAll()
uses regex to find its target, which I have replaced with "nothing" - effectively deleting the target.
The target I've specified by the regex \n.*
means "the newline char and everything after"
In python 3
>>> from pathlib import Path
>>> Path("/tmp/d/a.dat").name
'a.dat'
Your problem is not with the match / replacement, but that String is immutable, you need to assign the result:
str = str.replaceAll(",","."); // or "\\.", it doesn't matter...
You can use the Blob to get the string size in bytes.
Examples:
console.info(_x000D_
new Blob(['']).size, // 4_x000D_
new Blob(['']).size, // 4_x000D_
new Blob(['']).size, // 8_x000D_
new Blob(['']).size, // 8_x000D_
new Blob(['I\'m a string']).size, // 12_x000D_
_x000D_
// from Premasagar correction of Lauri's answer for_x000D_

// https://stackoverflow.com/a/39488643/6225838_x000D_
new Blob([String.fromCharCode(55555)]).size, // 3_x000D_

I once needed to upload PDFs to an online backup archive. But the backup would fail if the user had the file open in another program (such as PDF reader). In my haste, I attempted a few of the top answers in this thread but could not get them to work. What did work for me was trying to move the PDF file to its own directory. I found that this would fail if the file was open in another program, and if the move were successful there would be no restore-operation required as there would be if it were moved to a separate directory. I want to post my basic solution in case it may be useful for others' specific use cases.
string str_path_and_name = str_path + '\\' + str_filename;
FileInfo fInfo = new FileInfo(str_path_and_name);
bool open_elsewhere = false;
try
{
fInfo.MoveTo(str_path_and_name);
}
catch (Exception ex)
{
open_elsewhere = true;
}
if (open_elsewhere)

If you want to print something = '@'
2 times in a line, you can write this:
print(something * 2)
If you want to print 4 lines of something, you can use a for loop:
for i in range(4):
print(something)
You can use the csv
module to parse tab seperated value files easily.
import csv
with open("tab-separated-values") as tsv:
for line in csv.reader(tsv, dialect="excel-tab"): #You can also use delimiter="\t" rather than giving a dialect.
...
Where line
is a list of the values on the current row for each iteration.
Edit: As suggested below, if you want to read by column, and not by row, then the best thing to do is use the zip()
builtin:
with open("tab-separated-values") as tsv:
for column in zip(*[line for line in csv.reader(tsv, dialect="excel-tab")]):
...

Fixed positioning is supposed to define everything in relation to the viewport, so position:fixed
is always going to do that. Try using position:relative
on the child div instead.
(I realize you might need the fixed positioning for other reasons, but if so - you can't really make the width match it's parent with out JS without inherit
)
if it is cluster MongoDB then you need to add your current IP to the cluster, to add your current IP address you need to complete few steps below-
step 1- go to login page of Mongodb and login with valid credential - https://cloud.mongodb.com/user#/atlas/login
step 2- CLick Network Access from left sidebar under Security Section
Step 3 - Click Add IP Address
Step 4 - Click Add Current IP Address or Allow Connection From Any Where
now try to connect - npm start
and for Local MongoDB use mongo String like "mongodb+srv://username:pass%[email protected]/test?retryWrites=true&w=majority"
password must be encoded like example string
While you can call exit()
(and may need to do so if your application encounters some fatal error), the cleanest way to exit a program is to return from main()
:
int main()
{
// do whatever your program does
} // function returns and exits program
When you call exit()
, objects with automatic storage duration (local variables) are not destroyed before the program terminates, so you don't get proper cleanup. Those objects might need to clean up any resources they own, persist any pending state changes, terminate any running threads, or perform other actions in order for the program to terminate cleanly.
For-loop in C:
for(int x = 0; x<=3; x++)
{
//Do something!
}
The same loop in 8086 assembler:
xor cx,cx ; cx-register is the counter, set to 0
loop1 nop ; Whatever you wanna do goes here, should not change cx
inc cx ; Increment
cmp cx,3 ; Compare cx to the limit
jle loop1 ; Loop while less or equal
That is the loop if you need to access your index (cx). If you just wanna to something 0-3=4 times but you do not need the index, this would be easier:
mov cx,4 ; 4 iterations
loop1 nop ; Whatever you wanna do goes here, should not change cx
loop loop1 ; loop instruction decrements cx and jumps to label if not 0
If you just want to perform a very simple instruction a constant amount of times, you could also use an assembler-directive which will just hardcore that instruction
times 4 nop
Do-while-loop in C:
int x=1;
do{
//Do something!
}
while(x==1)
The same loop in assembler:
mov ax,1
loop1 nop ; Whatever you wanna do goes here
cmp ax,1 ; Check wether cx is 1
je loop1 ; And loop if equal
While-loop in C:
while(x==1){
//Do something
}
The same loop in assembler:
jmp loop1 ; Jump to condition first
cloop1 nop ; Execute the content of the loop
loop1 cmp ax,1 ; Check the condition
je cloop1 ; Jump to content of the loop if met
For the for-loops you should take the cx-register because it is pretty much standard. For the other loop conditions you can take a register of your liking. Of course replace the no-operation instruction with all the instructions you wanna perform in the loop.
If you are looking for generic usage, here is my suggestion:
Create a class named as Run
:
class Run {
companion object {
fun after(delay: Long, process: () -> Unit) {
Handler().postDelayed({
process()
}, delay)
}
}
}
And use like this:
Run.after(1000, {
// print something useful etc.
})
To use copying with xargs
to directories using wildcards on Mac OS, the only solution that worked for me with spaces in the directory name is:
find ./fs*/* -type d -print0 | xargs -0 -n 1 cp test
Where test
is the file to copy
And ./fs*/*
the directories to copy to
The problem is that xargs sees spaces as a new argument, the solutions to change the delimiter character using -d
or -E
is unfortunately not properly working on Mac OS.
Answer by @Ben proved to be useful for me. But I needed to check the product version as it was the main increment happening in my software and followed semantic versioning.
myFileVersionInfo.ProductVersion
This method met my expectations
Update: Instead of explicitly mentioning dll path in program (as needed in production version), we can get product version using Assembly.
Assembly assembly = Assembly.GetExecutingAssembly();
FileVersionInfo fileVersionInfo =FileVersionInfo.GetVersionInfo(assembly.Location);
string ProdVersion= fileVersionInfo.ProductVersion;
You are missing the fact that 6.999,50 is not a valid decimal. You can't have a comma and a decimal point in a decimal value surely? What number is it supposed to be?
Assuming your locale specifies . as grouping and , as decimal separator: To remove the grouping digits:
SELECT CONVERT(decimal(11,2), REPLACE('6.999,50', '.', ''))
will yield 6999,50 as a decimal

I think you are using 'global' incorrectly. See Python reference. You should declare variable without global and then inside the function when you want to access global variable you declare it global yourvar
.
#!/usr/bin/python
total
def checkTotal():
global total
total = 0
See this example:
#!/usr/bin/env python
total = 0
def doA():
# not accessing global total
total = 10
def doB():
global total
total = total + 1
def checkTotal():
# global total - not required as global is required
# only for assignment - thanks for comment Greg
print total
def main():
doA()
doB()
checkTotal()
if __name__ == '__main__':
main()
Because doA()
does not modify the global total the output is 1 not 11.

For those of you who want to execute a side-effect only if an optional is absent

// logic goes here
})
Are you familiar with other functional languages? i.e. are you trying to learn how python does functional programming, or are you trying to learn about functional programming and using python as the vehicle?
Also, do you understand list comprehensions?
map(f, sequence)
is directly equivalent (*) to:
[f(x) for x in sequence]
In fact, I think map()
was once slated for removal from python 3.0 as being redundant (that didn't happen).
map(f, sequence1, sequence2)
is mostly equivalent to:
[f(x1, x2) for x1, x2 in zip(sequence1, sequence2)]
(there is a difference in how it handles the case where the sequences are of different length. As you saw, map()
fills in None when one of the sequences runs out, whereas zip()
stops when the shortest sequence stops)
So, to address your specific question, you're trying to produce the result:
foos[0], bars
foos[1], bars
foos[2], bars
# etc.
You could do this by writing a function that takes a single argument and prints it, followed by bars:
def maptest(x):
print x, bars
map(maptest, foos)
Alternatively, you could create a list that looks like this:
[bars, bars, bars, ] # etc.
and use your original maptest:
def maptest(x, y):
print x, y
One way to do this would be to explicitely build the list beforehand:
barses = [bars] * len(foos)
map(maptest, foos, barses)
Alternatively, you could pull in the itertools
module. itertools
contains many clever functions that help you do functional-style lazy-evaluation programming in python. In this case, we want itertools.repeat
, which will output its argument indefinitely as you iterate over it. This last fact means that if you do:
map(maptest, foos, itertools.repeat(bars))
you will get endless output, since map()
keeps going as long as one of the arguments is still producing output. However, itertools.imap
is just like map()
, but stops as soon as the shortest iterable stops.
itertools.imap(maptest, foos, itertools.repeat(bars))
Hope this helps :-)
(*) It's a little different in python 3.0. There, map() essentially returns a generator expression.
Can you do this on the server, using Apache's mod_rewrite for example? If not, you can use the window.location.replace
method to erase the current URL from the back/forward history (to not break the back button) and go to the root of the web site:
window.location.replace('/');
Can do the following
PRINT dbo.[FunctionName] ( [Parameter/Argument] )
E.g.:
PRINT dbo.StringSplit('77,54')
If you are using emulator use Ctrl+M & simulator Cmd+D

You can use either "=" or "==" operators for string comparison in bash. The important factor is the spacing within the brackets. The proper method is for brackets to contain spacing within, and operators to contain spacing around. In some instances different combinations work; however, the following is intended to be a universal example.
if [ "$1" == "something" ]; then ## GOOD
if [ "$1" = "something" ]; then ## GOOD
if [ "$1"="something" ]; then ## BAD (operator spacing)
if ["$1" == "something"]; then ## BAD (bracket spacing)
Also, note double brackets are handled slightly differently compared to single brackets ...
if [[ $a == z* ]]; then # True if $a starts with a "z" (pattern matching).
if [[ $a == "z*" ]]; then # True if $a is equal to z* (literal matching).
if [ $a == z* ]; then # File globbing and word splitting take place.
if [ "$a" == "z*" ]; then # True if $a is equal to z* (literal matching).
I hope that helps!
As of Pandas version 0.22, there exists also an alternative to apply
: pipe
, which can be considerably faster than using apply
(you can also check this question for more differences between the two functionalities).
For your example:
df = pd.DataFrame({"my_label": ['A','B','A','C','D','D','E']})
my_label
0 A
1 B
2 A
3 C
4 D
5 D
6 E
The apply
version
df.groupby('my_label').apply(lambda grp: grp.count() / df.shape[0])
gives
my_label
my_label
A 0.285714
B 0.142857
C 0.142857
D 0.285714
E 0.142857
and the pipe
version
df.groupby('my_label').pipe(lambda grp: grp.size() / grp.size().sum())
yields
my_label
A 0.285714
B 0.142857
C 0.142857
D 0.285714
E 0.142857
So the values are identical, however, the timings differ quite a lot (at least for this small dataframe):
%timeit df.groupby('my_label').apply(lambda grp: grp.count() / df.shape[0])
100 loops, best of 3: 5.52 ms per loop
and
%timeit df.groupby('my_label').pipe(lambda grp: grp.size() / grp.size().sum())
1000 loops, best of 3: 843 µs per loop
Wrapping it into a function is then also straightforward:
def get_perc(grp_obj):
gr_size = grp_obj.size()
return gr_size / gr_size.sum()
Now you can call
df.groupby('my_label').pipe(get_perc)
yielding
my_label
A 0.285714
B 0.142857
C 0.142857
D 0.285714
E 0.142857
However, for this particular case, you do not even need a groupby
, but you can just use value_counts
like this:
df['my_label'].value_counts(sort=False) / df.shape[0]
yielding
A 0.285714
C 0.142857
B 0.142857
E 0.142857
D 0.285714
Name: my_label, dtype: float64
For this small dataframe it is quite fast
%timeit df['my_label'].value_counts(sort=False) / df.shape[0]
1000 loops, best of 3: 770 µs per loop
As pointed out by @anmol, the last statement can also be simplified to
df['my_label'].value_counts(sort=False, normalize=True)
I will go with ParentNode.children:
As it provides namedItem
method that allows me directly to get one of the children elements without looping through all children or avoiding to use getElementById
etc.
e.g.
ParentNode.children.namedItem('ChildElement-ID'); // JS
ref.current.children.namedItem('ChildElement-ID'); // React
this.$refs.ref.children.namedItem('ChildElement-ID'); // Vue
I will go with Node.childNodes:
As it provides forEach
method when I work with window.IntersectionObserver
e.g.
nodeList.forEach((node) => { observer.observe(node) })
// IE11 does not support forEach on nodeList, but easy to be polyfilled.
On Chrome 83
Node.childNodes provides
entries
,forEach
,item
,keys
,length
andvalues
ParentNode.children provides
item
,length
andnamedItem
You need to use parentheses: myList.insert([1, 2, 3])
. When you leave out the parentheses, python thinks you are trying to access myList.insert
at position 1, 2, 3
, because that's what brackets are used for when they are right next to a variable.
var getMatchingGroups = function(s) {
var r=/\((.*?)\)/g, a=[], m;
while (m = r.exec(s)) {
a.push(m[1]);
}
return a;
};
getMatchingGroups("something/([0-9])/([a-z])"); // => ["[0-9]", "[a-z]"]
In my case reason was too stupid :
I had a Constant.h file where I had macros defined. I thought of doing NSString there. and did this :
NSString const *kGreenColor = @"#00C34E";
this caused the problem of Duplicate Symbols for Architecture arm64 and Linker command failed with exit code 1. Removing const NSString line worked for me.
Create custom.js file inside ~/.jupyter/custom/ with following contents:
$("<style type='text/css'> .cell.code_cell.collapse { max-height:30px; overflow:hidden;} </style>").appendTo("head");
$('.prompt.input_prompt').on('click', function(event) {
console.log("CLICKED", arguments)
var c = $(event.target.closest('.cell.code_cell'))
if(c.hasClass('collapse')) {
c.removeClass('collapse');
} else {
c.addClass('collapse');
}
});
After saving, restart the server and refresh the notebook. You can collapse any cell by clicking on the input label (In[]).
Since not all datetime.datetime
instances have a microsecond component (i.e. when it is zero), you can partition the string on a "." and take only the first item, which will always work:
unicode(datetime.datetime.now()).partition('.')[0]
<http pattern="/resources/**" security="none"/>
Or with Java configuration:
web.ignoring().antMatchers("/resources/**");
Instead of the old:
<intercept-url pattern="/resources/**" filters="none"/>
for exp . disable security for a login page :
<intercept-url pattern="/login*" filters="none" />
In VB.NET, you need to use the GetType
method to retrieve the type of an instance of an object, and the GetType()
operator to retrieve the type of another known type.
Once you have the two types, you can simply compare them using the Is
operator.
So your code should actually be written like this:
Sub FillCategories(ByVal Obj As Object)
Dim cmd As New SqlCommand("sp_Resources_Categories", Conn)
cmd.CommandType = CommandType.StoredProcedure
Obj.DataSource = cmd.ExecuteReader
If Obj.GetType() Is GetType(System.Web.UI.WebControls.DropDownList) Then
End If
Obj.DataBind()
End Sub
You can also use the TypeOf
operator instead of the GetType
method. Note that this tests if your object is compatible with the given type, not that it is the same type. That would look like this:
If TypeOf Obj Is System.Web.UI.WebControls.DropDownList Then
End If
Totally trivial, irrelevant nitpick: Traditionally, the names of parameters are camelCased (which means they always start with a lower-case letter) when writing .NET code (either VB.NET or C#). This makes them easy to distinguish at a glance from classes, types, methods, etc.
Ignore me. I'm sorry everyone. I'd mistyped the url of the script. Thanks to Simon Ainley for the prod in the right direction.
Sorry again. Thanks.
This is the best way, I know of to create dynamic variables in python.
my_dict = {}
x = "Buffalo"
my_dict[x] = 4
I found a similar, but not the same question here Creating dynamically named variables from user input
I finally fixed this using the Google's camera app. It gets the phone's orientation by using a sensor and then sets the EXIF tag appropriately. The JPEG which comes out of the camera is not oriented automatically.
Also, the camera preview works properly only in the landscape mode. If you need your activity layout to be oriented in portrait, you will have to do it manually using the value from the orientation sensor.
Try this:
function funcName() {
alert("test");
}
var run = setInterval(funcName, 10000)
There are two ways to tackle this based on what you want:
Solution 1: Remove purple commits, preserving history (incase you want to roll back)
git revert -m 1 <SHA of merge>
-m 1
specifies which parent line to choose
Purple commits will still be there in history but since you have reverted, you will not see code from those commits.
Solution 2: Completely remove purple commits (disruptive change if repo is shared)
git rebase -i <SHA before branching out>
and delete (remove lines) corresponding to purple commits.
This would be less tricky if commits were not made after merge. Additional commits increase the chance of conflicts during revert/rebase
.
You have to figure out if the string is ascii encoded or encoded with a multi-byte format.
In the former case, you can just use strlen
.
In the latter case you need to find the number of bytes per character.
the strlen documentation gives an example of how to do it : http://www.php.net/manual/en/function.strlen.php#72274
i personally would prefer
if(true == foo)
{
}
there is no chance for the ==/= mistype and i find it more expressive in terms of foo's type. But it is a very subjective question.
If you are still getting an error that says "Default Activity not found" when you try to edit the run configurations even after executing:
Invalidate cache and Restart.
Then try deleting the Settings/Preferences folder:
/< USER_HOME_DIR >/.AndroidStudioPreview3.2
or on Mac :
/Users/<USER_NAME>/Library/Preferences/.AndroidStudioPreview3.2
There are two types of measurements you can use for specifying widths, heights, margins etc: relative and fixed.
An example of a relative measurement is percentages, which you have used. Percentages are relevant to their containing element. If there is no containing element they are relative to the window.
<div style="width:100%">
<!-- This div will be the full width of the browser, whatever size it is -->
<div style="width:300px">
<!-- this div will be 300px, whatever size the browser is -->
<p style="width:50%">
This paragraph's width will be 50% of it's parent (150px).
</p>
</div>
</div>
Another relative measurement is ems which are relative to font size.
An example of a fixed measurement is pixels but a fixed measurement can also be pt (points), cm (centimetres) etc. Fixed (sometimes called absolute) measurements are always the same size. A pixel is always a pixel, a centimetre is always a centimetre.
If you were to use fixed measurements for your sizes the browser size wouldn't affect the layout.
Another way assuming it's not server side code you want to comment out is...
<asp:panel runat="server" visible="false">
html here
</asp:panel>
I have installed both python 2.7.13 and python 3.6.1 on windows 10pro and I was getting the same "Fatal error" when I tried pip2 or pip3.
What I did to correct this was to go to the location of python.exe for python 2 and python 3 files and create a copy of each, I then renamed each copy to python2.exe and python3.exe depending on the python version in the installation folder. I therefore had in each python installation folder both a python.exe file and a python2.exe or python3.exe depending on the python version.
This resolved my problem when I typed either pip2 or pip3.
I updated extension method from @AminRostami to return IAsyncEnumerable (so LINQ filtering can be applied) and it's mapping Model Column name of records returned from DB to models (Tested with EF Core 5):
Extension itself:
public static class QueryHelper
{
private static string GetColumnName(this MemberInfo info)
{
List<ColumnAttribute> list = info.GetCustomAttributes<ColumnAttribute>().ToList();
return list.Count > 0 ? list.Single().Name : info.Name;
}
/// <summary>
/// Executes raw query with parameters and maps returned values to column property names of Model provided.
/// Not all properties are required to be present in model (if not present - null)
/// </summary>
public static async IAsyncEnumerable<T> ExecuteQuery<T>(
[NotNull] this DbContext db,
[NotNull] string query,
[NotNull] params SqlParameter[] parameters)
where T : class, new()
{
await using DbCommand command = db.Database.GetDbConnection().CreateCommand();
command.CommandText = query;
command.CommandType = CommandType.Text;
if (parameters != null)
{
foreach (SqlParameter parameter in parameters)
{
command.Parameters.Add(parameter);
}
}
await db.Database.OpenConnectionAsync();
await using DbDataReader reader = await command.ExecuteReaderAsync();
List<PropertyInfo> lstColumns = new T().GetType()
.GetProperties(BindingFlags.DeclaredOnly | BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic).ToList();
while (await reader.ReadAsync())
{
T newObject = new();
for (int i = 0; i < reader.FieldCount; i++)
{
string name = reader.GetName(i);
PropertyInfo prop = lstColumns.FirstOrDefault(a => a.GetColumnName().Equals(name));
if (prop == null)
{
continue;
}
object val = await reader.IsDBNullAsync(i) ? null : reader[i];
prop.SetValue(newObject, val, null);
}
yield return newObject;
}
}
}
Model used (note that Column names are different than actual property names):
public class School
{
[Key] [Column("SCHOOL_ID")] public int SchoolId { get; set; }
[Column("CLOSE_DATE", TypeName = "datetime")]
public DateTime? CloseDate { get; set; }
[Column("SCHOOL_ACTIVE")] public bool? SchoolActive { get; set; }
}
Actual usage:
public async Task<School> ActivateSchool(int schoolId)
{
// note that we're intentionally not returning "SCHOOL_ACTIVE" with select statement
// this might be because of certain IF condition where we return some other data
return await _context.ExecuteQuery<School>(
"UPDATE SCHOOL SET SCHOOL_ACTIVE = 1 WHERE SCHOOL_ID = @SchoolId; SELECT SCHOOL_ID, CLOSE_DATE FROM SCHOOL",
new SqlParameter("@SchoolId", schoolId)
).SingleAsync();
}
The id should set as auto-increment
.
To modify an existing id column to auto-increment, just add this
ALTER TABLE card_games MODIFY id int NOT NULL AUTO_INCREMENT;
Below is the code for drop down using MySql
and PHP
:
<?
$sql="Select PcID from PC"
$q=mysql_query($sql)
echo "<select name=\"pcid\">";
echo "<option size =30 ></option>";
while($row = mysql_fetch_array($q))
{
echo "<option value='".$row['PcID']."'>".$row['PcID']."</option>";
}
echo "</select>";
?>
If you have a single Buffer
you can use its toString
method that will convert all or part of the binary contents to a string using a specific encoding. It defaults to utf8
if you don't provide a parameter, but I've explicitly set the encoding in this example.
var req = http.request(reqOptions, function(res) {
...
res.on('data', function(chunk) {
var textChunk = chunk.toString('utf8');
// process utf8 text chunk
});
});
If you have streamed buffers like in the question above where the first byte of a multi-byte UTF8
-character may be contained in the first Buffer
(chunk) and the second byte in the second Buffer
then you should use a StringDecoder
. :
var StringDecoder = require('string_decoder').StringDecoder;
var req = http.request(reqOptions, function(res) {
...
var decoder = new StringDecoder('utf8');
res.on('data', function(chunk) {
var textChunk = decoder.write(chunk);
// process utf8 text chunk
});
});
This way bytes of incomplete characters are buffered by the StringDecoder
until all required bytes were written to the decoder.
using(StreamWriter writer = new StreamWriter("debug.txt", true))
{
writer.WriteLine("whatever you text is");
}
The second "true" parameter tells it to append.
While there are plenty of excellent Answers here, I'd like to present my own table describing the various Map
implementations bundled with Java 11.
We can see these differences listed on the table graphic:
HashMap
is the general-purpose Map
commonly used when you have no special needs.LinkedHashMap
extends HashMap
, adding this behavior: Maintains an order, the order in which the entries were originally added. Altering the value for key-value entry does not alter its place in the order.TreeMap
too maintains an order, but uses either (a) the “natural” order, meaning the value of the compareTo
method on the key objects defined on the Comparable
interface, or (b) invokes a Comparator
implementation you provide.
TreeMap
implements both the SortedMap
interface, and its successor, the NavigableMap
interface.TreeMap
does not allow a NULL as the key, while HashMap
& LinkedHashMap
do.
HashTable
is legacy, from Java 1. Supplanted by the ConcurrentHashMap
class. Quoting the Javadoc: ConcurrentHashMap
obeys the same functional specification as Hashtable
, and includes versions of methods corresponding to each method of Hashtable
.nodeName will give you the tag name in uppercase, while localName will give you the lower case.
$("yourelement")[0].localName
will give you : yourelement instead of YOURELEMENT
// Initiate set interval and assign it to intervalListener
var intervalListener = self.setInterval(function () {someProcess()}, 1000);
function someProcess() {
console.log('someProcess() has been called');
// If some condition is true clear the interval
if (stopIntervalIsTrue) {
window.clearInterval(intervalListener);
}
}
I would:
for _ in range(3):
do()
The _
is convention for a variable whose value you don't care about.
You might also see some people write:
[do() for _ in range(3)]
however that is slightly more expensive because it creates a list containing the return values of each invocation of do()
(even if it's None
), and then throws away the resulting list. I wouldn't suggest using this unless you are using the list of return values.
You may not have the UDP port open/VPN-forwarded, it's port number 1433.
Despite client protocol name of "TCP/IP", mssql uses UDP for bitbanging.
From my understanding matplotlib is a plotting library.
If you want to change the image data (e.g. draw a rectangle on an image), you could use PIL's ImageDraw, OpenCV, or something similar.
Here is PIL's ImageDraw method to draw a rectangle.
Here is one of OpenCV's methods for drawing a rectangle.
Your question asked about Matplotlib, but probably should have just asked about drawing a rectangle on an image.
Here is another question which addresses what I think you wanted to know: Draw a rectangle and a text in it using PIL
Java supports Regular Expressions, but they're kind of cumbersome if you actually want to use them to extract matches. I think the easiest way to get at the string you want in your example is to just use the Regular Expression support in the String
class's replaceAll
method:
String x = "test string (67)".replaceAll(".*\\(|\\).*", "");
// x is now the String "67"
This simply deletes everything up-to-and-including the first (
, and the same for the )
and everything thereafter. This just leaves the stuff between the parenthesis.
However, the result of this is still a String
. If you want an integer result instead then you need to do another conversion:
int n = Integer.parseInt(x);
// n is now the integer 67
Sometimes all the solutions with Workbooks.open is not working no matter how many parameters are set. For me, the fastest solution was to change the List separator in Region & language settings. Region window / Additional settings... / List separator.
If csv is not opening in proper way You probly have set ',' as a list separator. Just change it to ';' and everything is solved. Just the easiest way when "everything is against You" :P
For uploading, the S3 SDK has two putObject methods:
PutObjectRequest(String bucketName, String key, File file)
and
PutObjectRequest(String bucketName, String key, InputStream input, ObjectMetadata metadata)
The inputstream+ObjectMetadata method needs a minimum metadata of Content Length of your inputstream. If you don't, then it will buffer in-memory to get that information, this could cause OOM. Alternatively, you could do your own in-memory buffering to get the length, but then you need to get a second inputstream.
Not asked by the OP (limitations of his environment), but for someone else, such as me. I find it easier, and safer (if you have access to temp file), to write the inputstream to a temp file, and put the temp file. No in-memory buffer, and no requirement to create a second inputstream.
AmazonS3 s3Service = new AmazonS3Client(awsCredentials);
File scratchFile = File.createTempFile("prefix", "suffix");
try {
FileUtils.copyInputStreamToFile(inputStream, scratchFile);
PutObjectRequest putObjectRequest = new PutObjectRequest(bucketName, id, scratchFile);
PutObjectResult putObjectResult = s3Service.putObject(putObjectRequest);
} finally {
if(scratchFile.exists()) {
scratchFile.delete();
}
}
Use the quotemeta
function:
$text_to_search = "example text with [foo] and more";
$search_string = quotemeta "[foo]";
print "wee" if ($text_to_search =~ /$search_string/);
Response.Write("<script>window.opener.location.href = window.opener.location.href </script>");
I have the same issue today and I concur with Jack Leow. Basically, on Windows XP, I had to go to Control Panel > Java and then:

The error is caused because ElementTree did not expect to find non-ASCII strings set the XML when trying to write it out. You should use Unicode strings for non-ASCII instead. Unicode strings can be made either by using the u
prefix on strings, i.e. u'€'
or by decoding a string with mystr.decode('utf-8')
using the appropriate encoding.
The best practice is to decode all text data as it's read, rather than decoding mid-program. The io
module provides an open()
method which decodes text data to Unicode strings as it's read.
ElementTree will be much happier with Unicodes and will properly encode it correctly when using the ET.write()
method.
Also, for best compatibility and readability, ensure that ET encodes to UTF-8 during write()
and adds the relevant header.
Presuming your input file is UTF-8 encoded (0xC2
is common UTF-8 lead byte), putting everything together, and using the with
statement, your code should look like:
with io.open('myText.txt', "r", encoding='utf-8') as f:
data = f.read()
root = ET.Element("add")
doc = ET.SubElement(root, "doc")
field = ET.SubElement(doc, "field")
field.set("name", "text")
field.text = data
tree = ET.ElementTree(root)
tree.write("output.xml", encoding='utf-8', xml_declaration=True)
Output:
<?xml version='1.0' encoding='utf-8'?>
<add><doc><field name="text">data€</field></doc></add>

selenium.common.exceptions.WebDriverException: Message: unknown error: Chrome failed to start: crashed
(unknown error: DevToolsActivePort file doesn't exist)
(The process started from chrome location /opt/google/chrome/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.)
...implies that the ChromeDriver was unable to initiate/spawn a new WebBrowser i.e. Chrome Browser session.
Your main issue is the Chrome browser is not installed at the default location within your system.
The server i.e. ChromeDriver expects you to have Chrome installed in the default location for each system as per the image below:
1For Linux systems, the ChromeDriver expects /usr/bin/google-chrome
to be a symlink to the actual Chrome binary.
In case you are using a Chrome executable in a non-standard location you have to override the Chrome binary location as follows:
Python Solution:
from selenium import webdriver
from selenium.webdriver.chrome.options import Options
options = Options()
options.binary_location = "C:\\path\\to\\chrome.exe" #chrome binary location specified here
options.add_argument("--start-maximized") #open Browser in maximized mode
options.add_argument("--no-sandbox") #bypass OS security model
options.add_argument("--disable-dev-shm-usage") #overcome limited resource problems
options.add_experimental_option("excludeSwitches", ["enable-automation"])
options.add_experimental_option('useAutomationExtension', False)
driver = webdriver.Chrome(options=options, executable_path=r'C:\path\to\chromedriver.exe')
driver.get('http://google.com/')
Java Solution:
System.setProperty("webdriver.chrome.driver", "C:\\Utility\\BrowserDrivers\\chromedriver.exe");
ChromeOptions opt = new ChromeOptions();
opt.setBinary("C:\\Program Files (x86)\\Google\\Chrome\\Application\\chrome.exe"); //chrome binary location specified here
options.addArguments("start-maximized");
options.setExperimentalOption("excludeSwitches", Collections.singletonList("enable-automation"));
options.setExperimentalOption("useAutomationExtension", false);
WebDriver driver = new ChromeDriver(opt);
driver.get("https://www.google.com/");
Bill's answer is very good, but you may want to do some things with the request like compression or user-agents. The following code shows how you can various types of compression to your requests.
URL url = new URL(urlStr);
HttpURLConnection conn = (HttpURLConnection) url.openConnection(); // Cast shouldn't fail
HttpURLConnection.setFollowRedirects(true);
// allow both GZip and Deflate (ZLib) encodings
conn.setRequestProperty("Accept-Encoding", "gzip, deflate");
String encoding = conn.getContentEncoding();
InputStream inStr = null;
// create the appropriate stream wrapper based on
// the encoding type
if (encoding != null && encoding.equalsIgnoreCase("gzip")) {
inStr = new GZIPInputStream(conn.getInputStream());
} else if (encoding != null && encoding.equalsIgnoreCase("deflate")) {
inStr = new InflaterInputStream(conn.getInputStream(),
new Inflater(true));
} else {
inStr = conn.getInputStream();
}
To also set the user-agent add the following code:
conn.setRequestProperty ( "User-agent", "my agent name");
You can use this function in the route like this
app.get('/one/two', function (req, res) {
const url = getFullUrl(req);
}
/**
* Gets the self full URL from the request
*
* @param {object} req Request
* @returns {string} URL
*/
const getFullUrl = (req) => `${req.protocol}://${req.headers.host}${req.originalUrl}`;
req.protocol
will give you http or https,
req.headers.host
will give you the full host name like www.google.com,
req.originalUrl
will give the rest pathName
(in your case /one/two
)
You need to use the local set command below:
local set
git config user.email [email protected]
git config user.name 'Mahmoud Zalt'
local get
git config --get user.email
git config --get user.name
The local config file is in the project directory: .git/config
.
global set
git config --global user.email [email protected]
git config --global user.name 'Mahmoud Zalt'
global get
git config --global --get user.email
git config --global --get user.name
The global config file in in your home directory: ~/.gitconfig
.
Remember to quote blanks, etc, for example: 'FirstName LastName'
This alternative also provides a back function.
The template:
<a ng-click='back()'>Back</a>
The module:
myModule.run(function ($rootScope, $location) {
var history = [];
$rootScope.$on('$routeChangeSuccess', function() {
history.push($location.$$path);
});
$rootScope.back = function () {
var prevUrl = history.length > 1 ? history.splice(-2)[0] : "/";
$location.path(prevUrl);
};
});
As you all know, Spring Boot is a wonderful way of developing a WebApp or StandaloneApp with minimum configuration and opinionated Setup.

I declared my Web Filter in the following manner, adhering to Servlet Specifications 3.0
This is the Programmatic way of defining a Filter as a replacement to web.xml based definitions.
"@Webfilter" annotation will be processed by the container during deployment, the Filter class in which it is found will be created as per the configuration and applied to the URL patterns, javax.servlet.Servlets and javax.servlet.DispatcherTypes.
To avoid Web.xml completely and to achieve "Deployable" WebApp:-
To deploy Spring Boot Application as "Traditional WAR", the application class should extend SpringBootServletInitializer.
NOTE::
SpringBootServletInitializer is a "Programmatic Implementation" of web.xml with reference to Servlet 3.0+ specifications, which requires an implementation of WebApplicationInitializer.
Thus, SpringBootApplication doesn't require "web.xml" as its Application class (after extending SpringBootServletInitializer) scans for
- @WebFilter,
- @WebListener and
- @WebServlet.
Annotation @ServletComponentScan
This annotation enables scanning base packages for the web components annotated with @WebFilter, @WebListener and @WebServlet.
Due to the fact that embedded containers do not support @WebServlet, @WebFilter and @WebListener annotations, Spring Boot, relying greatly on embedded containers, introduced this new annotation @ServletComponentScan to support some dependent jars that use these 3 annotations.
Scanning is only performed when using an embedded Servlet container.
Following is my Spring Boot Application Class Definition:-
Custom Servlet Initializer:-
Here: I have defined a Custom Class: "ServletInitializer" which extends Class: SpringBootServletInitializer.
As explained earlier, SpringBootServletInitializer is responsible for scanning annotations:-
- @WebFilter,
- @WebListener and
- @WebServlet.
And hence the Spring Boot Application Class should
Adding two Int16
values result in an Int32
value. You will have to cast it to Int16
:
Int16 answer = (Int16) (firstNo + secondNo);
You can avoid this problem by switching all your numbers to Int32
.
I am working with Meteor and I just got the same problem. The cause of my bug was this:
{{#if tourmanager}}
{{>contactInformation tourmanager}}
{{else}}
<a href="#addArtistTourmanagerModal" data-toggle="modal"><i class="fa fa-plus"></i> Tourmanager toevoegen</a>
{{>addArtistTourmanagerModal}}
{{/if}}
As you can see I added the modal in the else, so when my modal updated the contactinformation the if had another state. This caused the modal template to be left out of the DOM just before it would close.
The solution: move the modal out of the if-else:
{{#if tourmanager}}
{{>contactInformation tourmanager}}
{{else}}
<a href="#addArtistTourmanagerModal" data-toggle="modal"><i class="fa fa-plus"></i> Tourmanager toevoegen</a>
{{>addArtistTourmanagerModal}}
{{/if}}
I found this as an easiest way to add row . The awesome thing about this is that it doesn't change the already present table contents even if it contains input elements .
row = `<tr><td><input type="text"></td></tr>`
$("#table_body tr:last").after(row) ;
Here #table_body
is the id of the table body tag .

Use this package, it just works: https://github.com/jdunck/python-unicodecsv.
Use ClassLoader#getResource()
instead if its URI represents a valid local disk file system path.
URL resource = classLoader.getResource("resource.ext");
File file = new File(resource.toURI());
FileInputStream input = new FileInputStream(file);
// ...
If it doesn't (e.g. JAR), then your best bet is to copy it into a temporary file.
Path temp = Files.createTempFile("resource-", ".ext");
Files.copy(classLoader.getResourceAsStream("resource.ext"), temp, StandardCopyOption.REPLACE_EXISTING);
FileInputStream input = new FileInputStream(temp.toFile());
// ...
That said, I really don't see any benefit of doing so, or it must be required by a poor helper class/method which requires FileInputStream
instead of InputStream
. If you can, just fix the API to ask for an InputStream
instead. If it's a 3rd party one, by all means report it as a bug. I'd in this specific case also put question marks around the remainder of that API.
Depends on what you're doing.
For instance:
//bankers' rounding - midpoint goes to nearest even
GetIntPart(2.5) >> 2
GetIntPart(5.5) >> 6
GetIntPart(-6.5) >> -6
or
//arithmetic rounding - midpoint goes away from zero
GetIntPart(2.5) >> 3
GetIntPart(5.5) >> 6
GetIntPart(-6.5) >> -7
The default is always the former, which can be a surprise but makes very good sense.
Your explicit cast will do:
int intPart = (int)343564564.5
// intPart will be 343564564
int intPart = (int)343564565.5
// intPart will be 343564566
From the way you've worded the question it sounds like this isn't what you want - you want to floor it every time.
I would do:
Math.Floor(Math.Abs(number));
Also check the size of your decimal
- they can be quite big, so you may need to use a long
.
Try this. It will work just fine:
int week = Convert.ToInt32(currentDateTime.DayOfWeek);
You need the -ExecutionPolicy
parameter:
Powershell.exe -executionpolicy remotesigned -File C:\Users\SE\Desktop\ps.ps1
Otherwise PowerShell considers the arguments a line to execute and while Set-ExecutionPolicy
is a cmdlet, it has no -File
parameter.
Change into the directory and;
attrib.exe /s ./*.* |find /c /v ""
I presumed that would be simple to discover. use
Process p = new Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
p.StartInfo.FileName = "batchfile.bat";
p.Start();
string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();
I run this and the variable output
was holding this
D:\VSS\USSD V3.0\WTU.USSD\USSDConsole\bin\Debug>attrib.exe /s ./*.* | find /c /v "" 13
where 13 is the file count. It should solve the issue
U+F0FE ?
is not a checkbox, it's a Private Use Area character that might render as anything. Whilst you can certainly try to include it in an HTML document, either directly in a UTF-8 document, or as a character reference like 
, you shouldn't expect it to render as a checkbox. It certainly doesn't on any of my browsers—although on some the ‘unknown character’ glyph is a square box that at least looks similar!
So where does U+F0FE come from? It is an unfortunate artifact of Word RTF export where the original document used a symbol font: one with no standard mapping to normal unicode characters; specifically, in this case, Wingdings. If you need to accept Word RTF from documents still authored with symbol fonts, then you will need to map those symbol characters to proper Unicode characters. Unfortunately that's tricky as it requires you to know the particular symbol font and have a map for it. See this post for background.
The standardised Unicode characters that best represent a checkbox are:
?
, U+2610 Ballot box?
, U+2611 Ballot box with checkIf you don't have a Unicode-safe editor you can naturally spell them as ☐
and ☑
.
(There is also U+2612 using an X, ?
.)
It seems you are hitting a UTF-8 byte order mark (BOM). Try using this unicode string with BOM extracted out:
import codecs
content = unicode(q.content.strip(codecs.BOM_UTF8), 'utf-8')
parser.parse(StringIO.StringIO(content))
I used strip
instead of lstrip
because in your case you had multiple occurences of BOM, possibly due to concatenated file contents.
document.getElementById()
method accepts only one argument.
However, you may always set classes to the elements and use getElementsByClassName()
instead. Another option for modern browsers is to use querySelectorAll()
method:
document.querySelectorAll("#myCircle1, #myCircle2, #myCircle3, #myCircle4");
x
is used to print t pointer argument in hexadecimal.
A typical address when printed using %x
would look like bfffc6e4
and the sane address printed using %p
would be 0xbfffc6e4
TextView textv = (TextView) findViewById(R.id.textview1);
textv.setShadowLayer(1, 0, 0, Color.BLACK);
The answers given so far are not ideal because they require a lot of needless work resolving merge conflicts, or they make too many assumptions which are frequently false. This is how to do it perfectly. The link is to my own site.
You have uncommited changes on my_branch
that you want to commit to master
, without committing all the changes from my_branch
.
git merge master
git stash -u
git checkout master
git stash apply
git reset
git add example.js
git commit
git checkout .
git clean -f -d
git checkout my_branch
git merge master
git stash pop
Start by merging master
into your branch, since you'll have to do that eventually anyway, and now is the best time to resolve any conflicts.
The -u
option (aka --include-untracked
) in git stash -u
prevents you from losing untracked files when you later do git clean -f -d
within master
.
After git checkout master
it is important that you do NOT git stash pop
, because you will need this stash later. If you pop the stash created in my_branch
and then do git stash
in master
, you will cause needless merge conflicts when you later apply that stash in my_branch
.
git reset
unstages everything resulting from git stash apply
. For example, files that have been modified in the stash but do not exist in master
get staged as "deleted by us" conflicts.
git checkout .
and git clean -f -d
discard everything that isn't committed: all changes to tracked files, and all untracked files and directories. They are already saved in the stash and if left in master
would cause needless merge conflicts when switching back to my_branch
.
The last git stash pop
will be based on the original my_branch
, and so will not cause any merge conflicts. However, if your stash contains untracked files which you have committed to master, git will complain that it "Could not restore untracked files from stash". To resolve this conflict, delete those files from your working tree, then git stash pop
, git add .
, and git reset
.
All, I want to let you all know that I was having this same issue. I solve it by resetting my remote URL git remote set-url origin https://new.url.here I found how to do this from this answer but I had to change hit to https: Change the URI (URL) for a remote Git repository
Updated version of HCD's solution which avoids conflict:

when we pass vector by value in a function as an argument,it simply creates the copy of vector and no any effect happens on the vector which is defined in main function when we call that particular function. while when we pass vector by reference whatever is written in that particular function, every action will going to perform on the vector which is defined in main or other function when we call that particular function.

Steps I did:
Init cookies as being NOT http-only in server-side app.'s:
app.configure(function(){
//a bunch of stuff
app.use(express.cookieSession({secret: 'mySecret', store: store, cookie: cookieSettings}));```
Then in client-side services.jss I put ['ngCookies'] in like this:
angular.module('swrp', ['ngCookies']).//etc
Then in controller.js
, in my function UserLoginCtrl
, I have $cookies
in there with $scope
at the top like so:
function UserLoginCtrl($scope, $cookies, socket) {
Lastly, to get the value of a cookie inside the controller function I did:
var mySession = $cookies['connect.sess'];
Now you can send that back to the server from the client. Awesome. Wish they would've put this in the Angular.js documentation. I figured it out by just reading the actual code for angular-cookies.js directly.
In a couple of lines, Cygwin and PowerShell are different tools however if you have Cygwin installed you can run the Cygwin executables within a PowerShell session. I've gotten so used to PowerShell that now I no longer use grep, sort, awk, etc. There are pretty much built-in alternatives in PowerShell, and if not you can find a cmdlet out there.
The main tool I find myself using is ssh.exe, but within a PowerShell session.
It works great.

The NUMBER
type can be specified in different styles:
Resulting Resulting Precision Specification Precision Scale Check Comment ------------------------------------------------------------------------------- NUMBER NULL NULL NO 'maximum range and precision', values are stored 'as given' NUMBER(P, S) P S YES Error code: ORA-01438 NUMBER(P) P 0 YES Error code: ORA-01438 NUMBER(*, S) 38 S NO
Where the precision is the total number of digits and scale is the number of digits right or left (negative scale) of the decimal point.
Oracle specifies ORA-01438 as
value larger than specified precision allowed for this column
As noted in the table, this integrity check is only active if the precision is explicitly specified. Otherwise Oracle silently rounds the inserted or updated value using some unspecified method.
The easiest way:
Step 1: Open AndroidManifest.xml file
Step 2: Locate android:theme="@style/AppTheme" >

Here's a other way to do it using kotlin extensions:
val Int.dpToPx: Int
get() = Math.round(this * Resources.getSystem().displayMetrics.density)
val Int.pxToDp: Int
get() = Math.round(this / Resources.getSystem().displayMetrics.density)
and then it can be used like this from anywhere
12.dpToPx
244.pxToDp
If you want to find the control from code behind you have to use runat="server"
attribute on control. And then you can use Control.FindControl
.
<div class="tab-pane active" id="portlet_tab1" runat="server">
Control myControl1 = FindControl("portlet_tab1");
if(myControl1!=null)
{
//do stuff
}
If you use runat server and your control is inside the ContentPlaceHolder
you have to know the ctrl name would not be portlet_tab1 anymore. It will render with the ctrl00 format.
Something like: #ctl00_ContentPlaceHolderMain_portlet_tab1. You will have to modify name if you use jquery.
You can also do it using jQuery on client side without using the runat-server attribute:
<script type='text/javascript'>
$("#portlet_tab1").removeClass("Active");
</script>
FindIndex seems to be what you're looking for:
FindIndex(Predicate<T>)
Usage:
list1.FindIndex(x => x==5);
Example:
// given list1 {3, 4, 6, 5, 7, 8}
list1.FindIndex(x => x==5); // should return 3, as list1[3] == 5;
If the variable is interchangable, you must have logic somewhere that's determining which variable gets used. All you need to do is put the variable name in $variable
within that logic while you're doing everything else.
I think we're all having a hard time understanding what you're needing this for. Sample code or an explanation of what you're actually trying to do might help, but I suspect you're way, way overthinking this.
There is a problem with pylint, which I do not completely understood yet.
You can just import OpenCV with:

you probably don't have the correct arch in that lib, you can do a

and it should show you the arch's that are in that library... I am not sure how you are linking, but it probably isn't the right way (if libswiftcore is a factory library, if it is some add on library then it probably isn't compiled correctly)

Just to rule out the possibility you aren't actually trying to see the fragment on a GET/POST and actually want to know how to access that part of a URI object you have within your server-side code, it is under Uri.Fragment (MSDN docs).
You will have to define the functions inside your header file.
You cannot separate definition of template functions in to the source file and declarations in to header file.
When a template is used in a way that triggers its intstantation, a compiler needs to see that particular templates definition. This is the reason templates are often defined in the header file in which they are declared.
Reference:
C++03 standard, § 14.7.2.4:
The definition of a non-exported function template, a non-exported member function template, or a non-exported member function or static data member of a class template shall be present in every translation unit in which it is explicitly instantiated.
EDIT:
To clarify the discussion on the comments:
Technically, there are three ways to get around this linking problem:
.cpp
file. #include
the .cpp
file defining the template at the .cpp
file using the template. Each of them have their pros and cons,
Moving the defintions to header files may increase the code size(modern day compilers can avoid this) but will increase the compilation time for sure.
Using the explicit instantiation approach is moving back on to traditional macro like approach.Another disadvantage is that it is necessary to know which template types are needed by the program. For a simple program this is easy but for complicated program this becomes difficult to determine in advance.
While including cpp files is confusing at the same time shares the problems of both above approaches.
I find first method the easiest to follow and implement and hence advocte using it.
I think you would need a Tuple2 like class. Be sure that it's GetHashCode() and Equals() is based upon the two contained elements.
See Tuples in C#
The largest integer that can be represented in IEEE 754 double (64-bit) is the same as the largest value that the type can represent, since that value is itself an integer.
This is represented as 0x7FEFFFFFFFFFFFFF
, which is made up of:
0x7FE
(2046 which represents 1023 after the bias is subtracted) rather than 0x7FF
(2047 which indicates a NaN
or infinity).0xFFFFFFFFFFFFF
which is 52 bits all 1.In binary, the value is the implicit 1 followed by another 52 ones from the mantissa, then 971 zeros (1023 - 52 = 971) from the exponent.
The exact decimal value is:
179769313486231570814527423731704356798070567525844996598917476803157260780028538760589558632766878171540458953514382464234321326889464182768467546703537516986049910576551282076245490090389328944075868508455133942304583236903222948165808559332123348274797826204144723168738177180919299881250404026184124858368

I'm using python 3.4, requests 2.19.1:
'urllib3' is the logger to get now (no longer 'requests.packages.urllib3'). Basic logging will still happen without setting http.client.HTTPConnection.debuglevel
Form my point of view, below is my suggestions:
From here:
http://www.christianengvall.se/undo-pushed-merge-git/
git revert -m 1 <merge commit hash>
Git revert adds a new commit that rolls back the specified commit.
Using -m 1 tells it that this is a merge and we want to roll back to the parent commit on the master branch. You would use -m 2 to specify the develop branch.
let pattern = /^(?=.*[0-9])(?=.*[!@#$%^&*])(?=.*[a-z])(?=.*[A-Z])[a-zA-Z0-9!@#$%^&*]{6,16}$/;
//following will give you the result as true(if the password contains Capital, small letter, number and special character) or false based on the string format
let reee =pattern .test("helLo123@"); //true as it contains all the above
I find letter identifiers to be more readable and more indicative of parsed type:
1 - 7f / 10
1 - 7 / 10f
or:
1 - 7d / 10
1 - 7 / 10d
A pkg-config file describes all necessary compile-time and link-time flags and dependencies needed to use a library.
pkg-config --static --libs glfw3

First go to Wamp->Apache->Service->Test Port 80
If its being user by Microsoft HTTPAPI / 2.0
Then the solution is to manually stop the service named web deployment agent service
If you have Microsoft Sql Server installed, even though the IIS service is disabled, it keeps a web service named httpapi2.0 running.
Technically, you can too put image data in an img tag, using data URIs.
<img src="data:image/jpeg;base64,<?php echo base64_encode( $image_data ); ?>" />
There are some special circumstances where this could even be useful, although in most cases you're better off serving the image through a separate script like daiscog suggests.

Use setInverseBackgroundForced(true)
on the alert dialog builder to invert the background.
Yes:
bigInt.sign = !(number < 0);
The !
operator always evaluates to true
or false
. When converted to int
, these become 1
and 0
respectively.
Of course this is equivalent to:
bigInt.sign = (number >= 0);
Here the parentheses are redundant but I add them for clarity. All of the comparison and relational operator evaluate to true
or false
.
pip has a --no-dependencies
