You can also enter msinfo32
into the command line.
It will bring up all your system information. Then, in the find box, just enter processor
and it will show you your cores and logical processors for each CPU. I found this way to be easiest.
A lot of good answers already, but let me see if I can give you another viewpoint.
Simplifying things by quite a bit, you can view a framework as an application that is complete except for the actual functionality. You plug in the functionality and PRESTO! you have an application.
Consider, say, a GUI framework. The framework contains everything you need to make an application. Indeed you can often trivially make a minimal application with very few lines of source that does absolutely nothing -- but it does give you window management, sub-window management, menus, button bars, etc. That's the framework side of things. By adding your application functionality and "plugging it in" to the right places in the framework you turn this empty app that does nothing more than window management, etc. into a real, full-blown application.
There are similar types of frameworks for web apps, for server-side apps, etc. In each case the framework provides the bulk of the tedious, repetitive code (hopefully) while you provide the actual problem domain functionality. (This is the ideal. In reality, of course, the success of the framework is highly variable.)
I stress again that this is the simplified view of what a framework is. I'm not using scary terms like "Inversion of Control" and the like although most frameworks have such scary concepts built-in. Since you're a beginner, I thought I'd spare you the jargon and go with an easy simile.
Try this.
var dateAsString = DateTime.Now.ToString("dd/MM/yyyy");
// dateAsString = "09/07/2013"
You can replace an HTML Element
or Node
using Node.replaceWith(newNode)
.
This example should keep all attributes and childs from origin node:
const links = document.querySelectorAll('a')
links.forEach(link => {
const replacement = document.createElement('span')
// copy attributes
for (let i = 0; i < link.attributes.length; i++) {
const attr = link.attributes[i]
replacement.setAttribute(attr.name, attr.value)
}
// copy content
replacement.innerHTML = link.innerHTML
// or you can use appendChild instead
// link.childNodes.forEach(node => replacement.appendChild(node))
link.replaceWith(replacement)
})
If you have these elements:
<a href="#link-1">Link 1</a>
<a href="#link-2">Link 2</a>
<a href="#link-3">Link 3</a>
<a href="#link-4">Link 4</a>
After running above codes, you will end up with these elements:
<span href="#link-1">Link 1</span>
<span href="#link-2">Link 2</span>
<span href="#link-3">Link 3</span>
<span href="#link-4">Link 4</span>
Looking into this, it seems like the LibMan approach works best for my needs with adding Bootstrap. I like it because it is now built into Visual Studio 2017(15.8 or later) and has its own dialog boxes.
Update 6/11/2020: bootstrap 4.1.3 is now added by default with VS-2019.5 (Thanks to Harald S. Hanssen for noticing.)
The default method VS adds to projects uses Bower but it looks like it is on the way out. In the header of Microsofts bower page they write:
Following a couple links lead to Use LibMan with ASP.NET Core in Visual Studio where it shows how libs can be added using a built-in Dialog:
In Solution Explorer, right-click the project folder in which the files should be added. Choose Add > Client-Side Library. The Add Client-Side Library dialog appears: [source: Scott Addie 2018]
Then for bootstrap just (1) select the unpkg, (2) type in "bootstrap@.." (3) Install. After this, you would just want to verify all the includes in the _Layout.cshtml or other places are correct. They should be something like href="~/lib/bootstrap/dist/js/bootstrap...")
Here I am going to export 3 tables from database named myDB in an sql file named table.sql
mysqldump -u root -p myDB table1 table2 table3 > table.sql
If, as in my case, you would like to load the images from a local folder on your own machine, then there is a simple way to do it with a very short Windows batch file. This uses the ability to send the output of any command to a file using > (to overwrite a file) and >> (to append to a file).
Potentially, you could output a list of filenames to a plain text file like this:
dir /B > filenames.txt
However, reading in a text file requires more faffing around, so I output a javascript file instead, which can then be loaded in your to create a global variable with all the filenames in it.
echo var g_FOLDER_CONTENTS = mlString(function() { /*! > folder_contents.js
dir /B images >> folder_contents.js
echo */}); >> folder_contents.js
The reason for the weird function with comment inside notation is to get around the limitation on multi-line strings in Javascript. The output of the dir command cannot be formatted to write a correct string, so I found a workaround here.
function mlString(f) {
return f.toString().
replace(/^[^\/]+\/\*!?/, '').
replace(/\*\/[^\/]+$/, '');
}
Add this in your main code before the generated javascript file is run, and then you will have a global variable called g_FOLDER_CONTENTS, which is a string containing the output from the dir command. This can then be tokenized and you'll have a list of filenames, with which you can do what you like.
var filenames = g_FOLDER_CONTENTS.match(/\S+/g);
Here's an example of it all put together: image_loader.zip
In the example, run.bat generates the Javascript file and opens index.html, so you needn't open index.html yourself.
NOTE: .bat is an executable type in Windows, so open them in a text editor before running if you are downloading from some random internet link like this one.
If you are running Linux or OSX, you can probably do something similar to the batch file and produce a correctly formatted javascript string without any of the mlString faff.
In my case i had 3 projects, 1 main project and 2 sub projects referenced by main project.. So i updated the main project, leaving out sub project. That's where the conflict was. After i updated all my project everything worked just fine.
Please check this code, it works fine for me.
$data = array('shopid'=>3,'version'=> 1,'value=>1'); //here $data is dummy varaible
error_log(print_r($data,true), 3, $_SERVER['DOCUMENT_ROOT']."/your-file-name.log");
//In $data we can mention the error messege and create the log
LAravel 5.6
Auth::routes([
'register' => false, // Registration Routes...
'reset' => false, // Password Reset Routes...
'verify' => false, // Email Verification Routes...
]);
TL;DR: You should add a JProperty to a JObject. Simple. The index query returns a JValue, so figure out how to get the JProperty instead :)
The accepted answer is not answering the question as it seems. What if I want to specifically add a JProperty after a specific one? First, lets start with terminologies which really had my head worked up.
"name":"value"
.Now, when you query Json item using the index [], you are getting the JToken without the identifier, which might be a JContainer or a JValue (requires casting), but you cannot add anything after it, because it is only a value. You can change it itself, query more deep values, but you cannot add anything after it for example.
What you actually want to get is the property as whole, and then add another property after it as desired. For this, you use JOjbect.Property("name")
, and then create another JProperty of your desire and then add it after this using AddAfterSelf
method. You are done then.

This is the code I modified.
public class Program
{
public static void Main()
{
try
{
string jsonText = @"
{
""food"": {
""fruit"": {
""apple"": {
""colour"": ""red"",
""size"": ""small""
},
""orange"": {
""colour"": ""orange"",
""size"": ""large""
}
}
}
}";
var foodJsonObj = JObject.Parse(jsonText);
var bananaJson = JObject.Parse(@"{ ""banana"" : { ""colour"": ""yellow"", ""size"": ""medium""}}");
var fruitJObject = foodJsonObj["food"]["fruit"] as JObject;
fruitJObject.Property("orange").AddAfterSelf(new JProperty("banana", fruitJObject));
Console.WriteLine(foodJsonObj.ToString());
}
catch (Exception ex)
{
Console.WriteLine(ex.GetType().Name + ": " + ex.Message);
}
}
}
Fetch promises only reject with a TypeError when a network error occurs. Since 4xx and 5xx responses aren't network errors, there's nothing to catch. You'll need to throw an error yourself to use Promise#catch
.
A fetch Response conveniently supplies an ok
, which tells you whether the request succeeded. Something like this should do the trick:
fetch(url).then((response) => {
if (response.ok) {
return response.json();
} else {
throw new Error('Something went wrong');
}
})
.then((responseJson) => {
// Do something with the response
})
.catch((error) => {
console.log(error)
});
Your program is still running. You have to kill it by closing the command line window. If you press control alt delete, task manager, process`s (kill the ones that match your filename).
The Tag is just used to easily find your output, because the Output of LogCat can be sometimes very long. You can define somewhere in your class:
private static final String TAG = "myApp";
and use it when debugging
Log.v(TAG, "did something");
You can apply as well a Filter to only search for the tag.
You could probably write your own custom implementation of click/dblclick to have it wait for an extra click. I don't see anything in the core jQuery functions that would help you achieve this.
Quote from .dblclick() at the jQuery site
It is inadvisable to bind handlers to both the click and dblclick events for the same element. The sequence of events triggered varies from browser to browser, with some receiving two click events before the dblclick and others only one. Double-click sensitivity (maximum time between clicks that is detected as a double click) can vary by operating system and browser, and is often user-configurable.
Since the glyphicons image is a sprite, you really can't do that: fundamentally what you want is to limit the size of the background, but there's no way to specify how big the background is. Either you cut out the icon you want, size it down and use it, or use something like the input field prepend/append option (http://twitter.github.io/bootstrap/base-css.html#forms and then search for prepended inputs).
Android's Java API does not support javax.naming.* and many other javax.* stuff. You need to include the dependencies as separate jars.
If you want to allow a user to add a bunch of new MyObjects to the list, you can do it with a for loop: Let's say I'm creating an ArrayList of Rectangle objects, and each Rectangle has two parameters- length and width.
//here I will create my ArrayList:
ArrayList <Rectangle> rectangles= new ArrayList <>(3);
int length;
int width;
for(int index =0; index <3;index++)
{JOptionPane.showMessageDialog(null, "Rectangle " + (index + 1));
length = JOptionPane.showInputDialog("Enter length");
width = JOptionPane.showInputDialog("Enter width");
//Now I will create my Rectangle and add it to my rectangles ArrayList:
rectangles.add(new Rectangle(length,width));
//This passes the length and width values to the rectangle constructor,
which will create a new Rectangle and add it to the ArrayList.
}
There is something called 'locked reference' in excel which you can use for this, and you use $
symbols to lock a range. For your example, you would use:
=IF(B4<>"",B4/B$1,"")
This locks the 1
in B1
so that when you copy it to rows below, 1
will remain the same.
If you use $B$1
, the range will not change when you copy it down a row or across a column.
Go to Setting>Debug>Un-check close on end.
Static methods can not be overridden because there is nothing to override, as they would be two different methods. For example
static class Class1 {
public static int Method1(){
return 0;
}
}
static class Class2 extends Class1 {
public static int Method1(){
return 1;
}
}
public static class Main {
public static void main(String[] args){
//Must explicitly chose Method1 from Class1 or Class2
Class1.Method1();
Class2.Method1();
}
}
And yes static methods can be overloaded just like any other method.
You can deserialize directly to a list by using the TypeReference
wrapper. An example method:
public static <T> T fromJSON(final TypeReference<T> type,
final String jsonPacket) {
T data = null;
try {
data = new ObjectMapper().readValue(jsonPacket, type);
} catch (Exception e) {
// Handle the problem
}
return data;
}
And is used thus:
final String json = "";
Set<POJO> properties = fromJSON(new TypeReference<Set<POJO>>() {}, json);
In Windows 7 and later, this will do the trick for you
The menu item Copy as Path is not available in Windows XP.
Here how to do it using format()
print "bin_signedDate : ", ''.join(format(x, '08b') for x in bytevector)
It is important the 08b . That means it will be a maximum of 8 leading zeros be appended to complete a byte. If you don't specify this then the format will just have a variable bit length for each converted byte.
I found a good choice to be coc.nvim with the python language server.
It takes a bit of effort to set up. I got frustrated with jedi-vim, because it would always freeze vim for a bit when completing. coc.nvim doesn't do it because it's asyncronous, meaning that . It also gives you linting for your code. It supports many other languages and is highly configurable.
The python language server uses jedi so you get the same completion as you would get from jedi.
As many of the members suggested use LinkedHashSet to retain the order of the collection. U can wrap your set using this implementation.
SortedSet implementation can be used for sorted order but for your purpose use LinkedHashSet.
Also from the docs,
"This implementation spares its clients from the unspecified, generally chaotic ordering provided by HashSet, without incurring the increased cost associated with TreeSet. It can be used to produce a copy of a set that has the same order as the original, regardless of the original set's implementation:"
Source : http://docs.oracle.com/javase/6/docs/api/java/util/LinkedHashSet.html
eval isn't always evil. There are times where it's perfectly appropriate.
However, eval is currently and historically massively over-used by people who don't know what they're doing. That includes people writing JavaScript tutorials, unfortunately, and in some cases this can indeed have security consequences - or, more often, simple bugs. So the more we can do to throw a question mark over eval, the better. Any time you use eval you need to sanity-check what you're doing, because chances are you could be doing it a better, safer, cleaner way.
To give an all-too-typical example, to set the colour of an element with an id stored in the variable 'potato':
eval('document.' + potato + '.style.color = "red"');
If the authors of the kind of code above had a clue about the basics of how JavaScript objects work, they'd have realised that square brackets can be used instead of literal dot-names, obviating the need for eval:
document[potato].style.color = 'red';
...which is much easier to read as well as less potentially buggy.
(But then, someone who /really/ knew what they were doing would say:
document.getElementById(potato).style.color = 'red';
which is more reliable than the dodgy old trick of accessing DOM elements straight out of the document object.)
If You want to check only when scroll ended, in Vanilla JS, You can come up with a solution like this:
Super Super compact
var t
window.onresize = () => { clearTimeout(t) t = setTimeout(() => { resEnded() }, 500) }
function resEnded() { console.log('ended') }
All 3 possible combinations together (ES6)
var t
window.onresize = () => {
resizing(this, this.innerWidth, this.innerHeight) //1
if (typeof t == 'undefined') resStarted() //2
clearTimeout(t); t = setTimeout(() => { t = undefined; resEnded() }, 500) //3
}
function resizing(target, w, h) {
console.log(`Youre resizing: width ${w} height ${h}`)
}
function resStarted() {
console.log('Resize Started')
}
function resEnded() {
console.log('Resize Ended')
}
If you're getting something like getElementById call returns null
, it's probably because the function is running, but the ID hasn't had time to load in the DOM.
Try using Will's answer (towards the top) with a delay. Example:
angular.module('MyApp', [])
.controller('MyCtrl', [function() {
$scope.sleep = (time) => {
return new Promise((resolve) => setTimeout(resolve, time));
};
angular.element(document).ready(function () {
$scope.sleep(500).then(() => {
//code to run here after the delay
});
});
}]);
I also like itertuples()
for row in df.itertuples():
print(row.A)
print(row.Index)
since row is a named tuples, if you meant to access values on each row this should be MUCH faster
speed run :
df = pd.DataFrame([x for x in range(1000*1000)], columns=['A'])
st=time.time()
for index, row in df.iterrows():
row.A
print(time.time()-st)
45.05799984931946
st=time.time()
for row in df.itertuples():
row.A
print(time.time() - st)
0.48400020599365234
Convert your UTC date to Local Date
-(NSString *)getLocalDateTimeFromUTC:(NSString *)strDate
{
NSDateFormatter *dtFormat = [[NSDateFormatter alloc] init];
[dtFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
[dtFormat setTimeZone:[NSTimeZone timeZoneWithAbbreviation:@"UTC"]];
NSDate *aDate = [dtFormat dateFromString:strDate];
[dtFormat setDateFormat:@"yyyy-MM-dd HH:mm:ss"];
[dtFormat setTimeZone:[NSTimeZone systemTimeZone]];
return [dtFormat stringFromDate:aDate];
}
Use Like This
NSString *localDate = [self getLocalDateTimeFromUTC:@"yourUTCDate"];
$('#div_id').css({marginTop: '-=15px'});
This will alter the css for the element with the id "div_id"
To get the effect you want I recommend adding the code above to a callback function in your animation (that way the div will be moved up after the animation is complete):
$('#div_id').animate({...}, function () {
$('#div_id').css({marginTop: '-=15px'});
});
And of course you could animate the change in margin like so:
$('#div_id').animate({marginTop: '-=15px'});
Here are the docs for .css()
in jQuery: http://api.jquery.com/css/
And here are the docs for .animate()
in jQuery: http://api.jquery.com/animate/
Assume the date as milliseconds date is 1526813885836
, so you can access the date as string with this sample code:
console.log(new Date(1526813885836).toString());
For clearness see below code:
const theTime = new Date(1526813885836);
console.log(theTime.toString());
Just another possibility: Spring initializes bean by type not by name if you don't define bean with a name, which is ok if you use it by its type:
Producer:
@Service
public void FooServiceImpl implements FooService{}
Consumer:
@Autowired
private FooService fooService;
or
@Autowired
private void setFooService(FooService fooService) {}
but not ok if you use it by name:
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
ctx.getBean("fooService");
It would complain: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'fooService' is defined
In this case, assigning name to @Service("fooService")
would make it work.
My system was 32 bit. I removed and re-installed Notepad++. After that from below got PluginManager_v1.4.12_UNI.zip and extracted it.

I created a folder called PluginManager at C:\Program Files (x86)\Notepad++\plugins\ and copied PluginManager.dll into it. I restarted my notepad++ and now I see Plugin Manager.
Just to correct mingos' answer:
If you set the expiration time to 0, the cookie won't be created at all. I've tested this on Google Chrome at least, and when set to 0 that was the result. The cookie, I guess, expires immediately after creation.
To set a cookie so it expires at the end of the browsing session, simply OMIT the expiration parameter altogether.
Example:
Instead of:
document.cookie = "cookie_name=cookie_value; 0; path=/";
Just write:
document.cookie = "cookie_name=cookie_value; path=/";
1) Create a Dateable protocol
protocol Dateable {
func userFriendlyFullDate() -> String
func userFriendlyHours() -> String
}
2) Extend Date class and implement the Dateable protocol
extension Date: Dateable {
var formatter: DateFormatter { return DateFormatter() }
/** Return a user friendly hour */
func userFriendlyFullDate() -> String {
// Customize a date formatter
formatter.dateFormat = "yyyy-MM-dd'T'HH:mm:ss.SSSZ"
formatter.timeZone = TimeZone(abbreviation: "UTC")
return formatter.string(from: self)
}
/** Return a user friendly hour */
func userFriendlyHours() -> String {
// Customize a date formatter
formatter.dateFormat = "HH:mm"
formatter.timeZone = TimeZone(abbreviation: "UTC")
return formatter.string(from: self)
}
// You can add many cases you need like string to date formatter
}
3) Use it
let currentDate: Date = Date()
let stringDate: String = currentDate.userFriendlyHours()
// Print 15:16
$date = '2013-01-22';
$time = strtotime($date) + 86400;
echo date('Y-m-d', $time);
Where 86400 is the # of seconds in a day.
What are the differences in the applications of
Runnable
andCallable
. Is the difference only with the return parameter present inCallable
?
Basically, yes. See the answers to this question. And the javadoc for Callable
.
What is the need of having both if
Callable
can do all thatRunnable
does?
Because the Runnable
interface cannot do everything that Callable
does!
Runnable
has been around since Java 1.0, but Callable
was only introduced in Java 1.5 ... to handle use-cases that Runnable
does not support. In theory, the Java team could have changed the signature of the Runnable.run()
method, but this would have broken binary compatiblity with pre-1.5 code, requiring recoding when migrating old Java code to newer JVMs. That is a BIG NO-NO. Java strives to be backwards compatible ... and that's been one of Java's biggest selling points for business computing.
And, obviously, there are use-cases where a task doesn't need to return a result or throw a checked exception. For those use-cases, using Runnable
is more concise than using Callable<Void>
and returning a dummy (null
) value from the call()
method.
Another short oneliner:
mydict = {'c': 1, 'b': 2, 'a': 3}
print(*sorted(mydict.items()), sep='\n')
Adding this trick to gabriel garcia's following solution -
var img = 'data:image/png;base64, ...'; //place ur base64 encoded img here
document.body.style.backgroundImage = 'url(' + img + ')';
However, in my case this wasn't working. Moving url into the img variable did the trick. SO the final code looked like this
var img = "url('data:image/png;base64, "+base64Data + "')";
document.body.style.backgroundImage = img;
I know it's an old question and Path.GetFileNameWithoutExtension
is a better and maybe cleaner option. But personally I've added this two methods to my project and wanted to share them. This requires C# 8.0 due to it using ranges and indices.
public static string RemoveExtension(this string file) => ReplaceExtension(file, null);
public static string ReplaceExtension(this string file, string extension)
{
var split = file.Split('.');
if (string.IsNullOrEmpty(extension))
return string.Join(".", split[..^1]);
split[^1] = extension;
return string.Join(".", split);
}
Change <?php echo $proxy ?>
to ' . $proxy . '
.
You use <?php
when you're outputting HTML by leaving PHP mode with ?>
. When you using echo
, you have to use concatenation, or wrap your string in double quotes and use interpolation.
Things to Note here is your app will crash badly in either of two cases:-
1) In order to reuse fragment with Maps again MapView Fragment must be removed when your fragment showing Maps got replaced with other fragment in onDestroyView callback.
else when you try to inflate same fragment twice Duplicate ID, tag null, or parent id with another fragment for com.google.android.gms.maps.MapFragment error will happen.
2) Secondly you must not mix app.Fragment operations with android.support.v4.app.Fragment API operations eg.do not use android.app.FragmentTransaction to remove v4.app.Fragment type MapView Fragment. Mixing this will again result into crash from fragment side.

In Bootstrap 4, there is a new utility known as .mx-auto
. You just need to specify the width of the centered element.
Ref: http://v4-alpha.getbootstrap.com/utilities/spacing/#horizontal-centering
Diffferent from Bass Jobsen's answer, which is a relative center to the elements on both ends, the following example is absolute centered.
Here's the HTML:
<nav class="navbar bg-faded">
<div class="container">
<ul class="nav navbar-nav pull-sm-left">
<li class="nav-item">
<a class="nav-link" href="#">Link 1</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link 2</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link 3</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link 4</a>
</li>
</ul>
<ul class="nav navbar-nav navbar-logo mx-auto">
<li class="nav-item">
<a class="nav-link" href="#">Brand</a>
</li>
</ul>
<ul class="nav navbar-nav pull-sm-right">
<li class="nav-item">
<a class="nav-link" href="#">Link 5</a>
</li>
<li class="nav-item">
<a class="nav-link" href="#">Link 6</a>
</li>
</ul>
</div>
</nav>
And CSS:
.navbar-logo {
width: 90px;
}
cities.reject! { |c| c.blank? }
The reason you want to use blank?
over empty?
is that blank recognizes nil, empty strings, and white space. For example:
cities = ["Kathmandu", "Pokhara", " ", nil, "", "Dharan", "Butwal"].reject { |c| c.blank? }
would still return:
["Kathmandu", "Pokhara", "Dharan", "Butwal"]
And calling empty?
on " "
will return false
, which you probably want to be true
.
Note: blank?
is only accessible through Rails, Ruby only supports empty?
.
In the opening tag of your form, set an action attribute like so:
<form id="contactForm" action="#">
From my past experience, I found that different browsers deal with trailing commas in JSON differently.
Both Firefox and Chrome handles it just fine. But IE (All versions) seems to break. I mean really break and stop reading the rest of the script.
Keeping that in mind, and also the fact that it's always nice to write compliant code, I suggest spending the extra effort of making sure that there's no trailing comma.
:)
Like so:
filtered_list = [i for (i, v) in zip(list_a, filter) if v]
Using zip
is the pythonic way to iterate over multiple sequences in parallel, without needing any indexing. This assumes both sequences have the same length (zip stops after the shortest runs out). Using itertools
for such a simple case is a bit overkill ...
One thing you do in your example you should really stop doing is comparing things to True, this is usually not necessary. Instead of if filter[idx]==True: ...
, you can simply write if filter[idx]: ...
.
No need for jQuery
var type = window.location.hash.substr(1);
My current reputation does not yet allow to post this as a comment. Stans solution to enter the debug mode, press twice Ctrl+Break, play on, save did solve my problem, but I have two unexpected twists:
My project struture is password protected, so in order to get into the Debug Mode I had to first enter Developer mode, click on the project structure and enter the password.
My project is a template file (.xmtl). I opened the file via double click which opens it as .xml with a "1" at the end of the previous file name. I fixed the bug as by Stans instruction and saved it as that ...1.xml file. When I then opened the template again, this time as template, and wanted to apply the same bug fix to that file, the bug was gone! I did not change this file and still no bug at executing the Macro. This means to me that the bug is not actually in the file, but in a (hidden) setting in Excel.
If you're using GNU find
, you can try -execdir
parameter, e.g.:
find . -type d -execdir realpath "{}" ';'
or (as per @gniourf_gniourf comment):
find . -type d -execdir sh -c 'printf "%s/%s\n" "$PWD" "$0"' {} \;
Note: You can use ${0#./}
instead of $0
to fix ./
in the front.
or more practical example:
find . -name .git -type d -execdir git pull -v ';'
If you want to include the current directory, it's even simpler by using -exec
:
find . -type d -exec sh -c 'cd -P -- "{}" && pwd -P' \;
or using xargs
:
find . -type d -print0 | xargs -0 -L1 sh -c 'cd "$0" && pwd && echo Do stuff'
Or similar example suggested by @gniourf_gniourf:
find . -type d -print0 | while IFS= read -r -d '' file; do
# ...
done
The above examples support directories with spaces in their name.
Or by assigning into bash array:
dirs=($(find . -type d))
for dir in "${dirs[@]}"; do
cd "$dir"
echo $PWD
done
Change .
to your specific folder name. If you don't need to run recursively, you can use: dirs=(*)
instead. The above example doesn't support directories with spaces in the name.
So as @gniourf_gniourf suggested, the only proper way to put the output of find in an array without using an explicit loop will be available in Bash 4.4 with:
mapfile -t -d '' dirs < <(find . -type d -print0)
Or not a recommended way (which involves parsing of ls
):
ls -d */ | awk '{print $NF}' | xargs -n1 sh -c 'cd $0 && pwd && echo Do stuff'
The above example would ignore the current dir (as requested by OP), but it'll break on names with the spaces.

I was looking for a inline editing solution and I found a plunker that seemed promising, but it didn't work for me out of the box. After some tinkering with the code I got it working. Kudos to the person who made the initial effort to code this piece.
The example is available here http://plnkr.co/edit/EsW7mV?p=preview
Here goes the code:
app.controller('MainCtrl', function($scope) {
$scope.updateTodo = function(indx) {
console.log(indx);
};
$scope.cancelEdit = function(value) {
console.log('Canceled editing', value);
};
$scope.todos = [
{id:123, title: 'Lord of the things'},
{id:321, title: 'Hoovering heights'},
{id:231, title: 'Watership brown'}
];
});
// On esc event
app.directive('onEsc', function() {
return function(scope, elm, attr) {
elm.bind('keydown', function(e) {
if (e.keyCode === 27) {
scope.$apply(attr.onEsc);
}
});
};
});
// On enter event
app.directive('onEnter', function() {
return function(scope, elm, attr) {
elm.bind('keypress', function(e) {
if (e.keyCode === 13) {
scope.$apply(attr.onEnter);
}
});
};
});
// Inline edit directive
app.directive('inlineEdit', function($timeout) {
return {
scope: {
model: '=inlineEdit',
handleSave: '&onSave',
handleCancel: '&onCancel'
},
link: function(scope, elm, attr) {
var previousValue;
scope.edit = function() {
scope.editMode = true;
previousValue = scope.model;
$timeout(function() {
elm.find('input')[0].focus();
}, 0, false);
};
scope.save = function() {
scope.editMode = false;
scope.handleSave({value: scope.model});
};
scope.cancel = function() {
scope.editMode = false;
scope.model = previousValue;
scope.handleCancel({value: scope.model});
};
},
templateUrl: 'inline-edit.html'
};
});
Directive template:
<div>
<input type="text" on-enter="save()" on-esc="cancel()" ng-model="model" ng-show="editMode">
<button ng-click="cancel()" ng-show="editMode">cancel</button>
<button ng-click="save()" ng-show="editMode">save</button>
<span ng-mouseenter="showEdit = true" ng-mouseleave="showEdit = false">
<span ng-hide="editMode" ng-click="edit()">{{model}}</span>
<a ng-show="showEdit" ng-click="edit()">edit</a>
</span>
</div>
To use it just add water:
<div ng-repeat="todo in todos"
inline-edit="todo.title"
on-save="updateTodo($index)"
on-cancel="cancelEdit(todo.title)"></div>
UPDATE:
Another option is to use the readymade Xeditable for AngularJS:
Yet another cause of this error is when you are calling the stored procedure from code, and the parameter type in code does not match the type on the stored procedure.
The short answer is: It is possible, and can be done with either a special HTTP proxy or a SOCKS proxy.
First and foremost, HTTPS uses SSL/TLS which by design ensures end-to-end security by establishing a secure communication channel over an insecure one. If the HTTP proxy is able to see the contents, then it's a man-in-the-middle eavesdropper and this defeats the goal of SSL/TLS. So there must be some tricks being played if we want to proxy through a plain HTTP proxy.
The trick is, we turn an HTTP proxy into a TCP proxy with a special command named CONNECT
. Not all HTTP proxies support this feature but many do now. The TCP proxy cannot see the HTTP content being transferred in clear text, but that doesn't affect its ability to forward packets back and forth. In this way, client and server can communicate with each other with help of the proxy. This is the secure way of proxying HTTPS data.
There is also an insecure way of doing so, in which the HTTP proxy becomes a man-in-the-middle. It receives the client-initiated connection, and then initiate another connection to the real server. In a well implemented SSL/TLS, the client will be notified that the proxy is not the real server. So the client has to trust the proxy by ignoring the warning for things to work. After that, the proxy simply decrypts data from one connection, reencrypts and feeds it into the other.
Finally, we can certainly proxy HTTPS through a SOCKS proxy, because the SOCKS proxy works at a lower level. You may think a SOCKS proxy as both a TCP and a UDP proxy.
I am not 100% sure what the conditions are for this, but for me the above didn't work directly, thought it got close. I think it was because I needed "id" for my view by in the model it was called "ObjectID".
I had a model with a variety of pieces of information. I just needed the id.
Before the above I created a new System.Web.Routing.RouteValueDictionary object and added the needed id.
(System.Web.Routing.)RouteValueDictionary RouteInfo = new RouteValueDictionary();
RouteInfo.Add("id", ObjectID);
return RedirectToAction("details", RouteInfo);
(Note: the MVC project in question I didn't create, so I don't know where all the right "fiddly" bits are.)
Change . to / as the path separator and use getResourceAsStream
:
reader = new BufferedReader(new InputStreamReader(
getClass().getClassLoader().getResourceAsStream(
"com/company/app/dao/sql/SqlQueryFile.sql")));
or
reader = new BufferedReader(new InputStreamReader(
getClass().getResourceAsStream(
"/com/company/app/dao/sql/SqlQueryFile.sql")));
Note the leading slash when using Class.getResourceAsStream()
vs ClassLoader.getResourceAsStream
.
getSystemResourceAsStream
uses the system classloader which isn't what you want.
I suspect that using slashes instead of dots would work for ClassPathResource
too.
I fond this YouTube video from Google where are some tips and tricks for it. The video also includes advantages and disadvantages of suggested changes.
Improving Android Studio Performance on Memory-Constrained Machines
If you are using older versions of Powershell where Test-NetConnection isn't available, here is a one-liner for hostname "my.hostname" and port "123":
$t = New-Object System.Net.Sockets.TcpClient 'my.hostname', 123; if($t.Connected) {"OK"}
Returns OK, or an error message.
If using a plugin is ok in you case, then I suggest Ben Alman's clickoutside plugin located here:
its usage is as simple as this:
$('#menu').bind('clickoutside', function (event) {
$(this).hide();
});
hope this helps.
The solution is much too big. Try this simple one. Please provide a 7+ character buffer, no check made.
char *i2str(int i, char *buf){
byte l=0;
if(i<0) buf[l++]='-';
boolean leadingZ=true;
for(int div=10000, mod=0; div>0; div/=10){
mod=i%div;
i/=div;
if(!leadingZ || i!=0){
leadingZ=false;
buf[l++]=i+'0';
}
i=mod;
}
buf[l]=0;
return buf;
}
Can be easily modified to give back end of buffer, if you discard index 'l' and increment the buffer directly.
In addittion, you can do in a Fragment (for example when getting server data failed):
getView().setVisibility(View.GONE);
This works for me:
protected boolean isTypeOf(String myClass, Class<?> superClass) {
boolean isSubclassOf = false;
try {
Class<?> clazz = Class.forName(myClass);
if (!clazz.equals(superClass)) {
clazz = clazz.getSuperclass();
isSubclassOf = isTypeOf(clazz.getName(), superClass);
} else {
isSubclassOf = true;
}
} catch(ClassNotFoundException e) {
/* Ignore */
}
return isSubclassOf;
}
Fast, simple, but maybe not always right:
>>> [x for x in mylist if x.isdigit()]
['1', '2', '3', '4']
More traditional if you need to get numbers:
new_list = []
for value in mylist:
try:
new_list.append(int(value))
except ValueError:
continue
Note: The result has integers. Convert them back to strings if needed, replacing the lines above with:
try:
new_list.append(str(int(value)))
User order by with that field, and then do distinct.
ProductOrder.objects.order_by('category').values_list('category', flat=True).distinct()
An object is defined by an OBJECT_ID, which is unique. If A and B are objects and A == B is true, then they are the very same object, they have the same data and methods, but, this is also true:
A.OBJECT_ID == B.OBJECT_ID
if A.Equals(B) is true, that means that the two objects are in the same state, but this doesn't mean that A is the very same as B.
Strings are objects.
Note that the == and Equals operators are reflexive, simetric, tranzitive, so they are equivalentic relations (to use relational algebraic terms)
What this means: If A, B and C are objects, then:
(1) A == A is always true; A.Equals(A) is always true (reflexivity)
(2) if A == B then B == A; If A.Equals(B) then B.Equals(A) (simetry)
(3) if A == B and B == C, then A == C; if A.Equals(B) and B.Equals(C) then A.Equals(C) (tranzitivity)
Also, you can note that this is also true:
(A == B) => (A.Equals(B)), but the inverse is not true.
A B =>
0 0 1
0 1 1
1 0 0
1 1 1
Example of real life: Two Hamburgers of the same type have the same properties: they are objects of the Hamburger class, their properties are exactly the same, but they are different entities. If you buy these two Hamburgers and eat one, the other one won't be eaten. So, the difference between Equals and ==: You have hamburger1 and hamburger2. They are exactly in the same state (the same weight, the same temperature, the same taste), so hamburger1.Equals(hamburger2) is true. But hamburger1 == hamburger2 is false, because if the state of hamburger1 changes, the state of hamburger2 not necessarily change and vice versa.
If you and a friend get a Hamburger, which is yours and his in the same time, then you must decide to split the Hamburger into two parts, because you.getHamburger() == friend.getHamburger() is true and if this happens: friend.eatHamburger(), then your Hamburger will be eaten too.
I could write other nuances about Equals and ==, but I'm getting hungry, so I have to go.

I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.
Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled
Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is
Here is the xmlns reference:
xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
Then the ad itself:
<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480" AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>

Add an EditText on top of your listview in its .xml layout file. And in your activity/fragment..
lv = (ListView) findViewById(R.id.list_view);
inputSearch = (EditText) findViewById(R.id.inputSearch);
// Adding items to listview
adapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.product_name, products);
lv.setAdapter(adapter);
inputSearch.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) {
// When user changed the Text
MainActivity.this.adapter.getFilter().filter(cs);
}
@Override
public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { }
@Override
public void afterTextChanged(Editable arg0) {}
});
The basic here is to add an OnTextChangeListener to your edit text and inside its callback method apply filter to your listview's adapter.
EDIT
To get filter to your custom BaseAdapter you"ll need to implement Filterable interface.
class CustomAdapter extends BaseAdapter implements Filterable {
public View getView(){
...
}
public Integer getCount()
{
...
}
@Override
public Filter getFilter() {
Filter filter = new Filter() {
@SuppressWarnings("unchecked")
@Override
protected void publishResults(CharSequence constraint, FilterResults results) {
arrayListNames = (List<String>) results.values;
notifyDataSetChanged();
}
@Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
ArrayList<String> FilteredArrayNames = new ArrayList<String>();
// perform your search here using the searchConstraint String.
constraint = constraint.toString().toLowerCase();
for (int i = 0; i < mDatabaseOfNames.size(); i++) {
String dataNames = mDatabaseOfNames.get(i);
if (dataNames.toLowerCase().startsWith(constraint.toString())) {
FilteredArrayNames.add(dataNames);
}
}
results.count = FilteredArrayNames.size();
results.values = FilteredArrayNames;
Log.e("VALUES", results.values.toString());
return results;
}
};
return filter;
}
}
Inside performFiltering() you need to do actual comparison of the search query to values in your database. It will pass its result to publishResults() method.
I think you declared the Equals
method like this:
public override bool Equals(BOX obj)
Since the object.Equals
method takes an object, there is no method to override with this signature. You have to override it like this:
public override bool Equals(object obj)
If you want type-safe Equals,
you can implement IEquatable<BOX>
.
ng serve --port 122345 is worked fine for me.
You could use random.sample
to generate the list with one call:
import random
my_randoms = random.sample(range(100), 10)
That generates numbers in the (inclusive) range from 0 to 99. If you want 1 to 100, you could use this (thanks to @martineau for pointing out my convoluted solution):
my_randoms = random.sample(range(1, 101), 10)
paramiko finally worked for me after adding additional line, which is really important one (line 3):
import paramiko
p = paramiko.SSHClient()
p.set_missing_host_key_policy(paramiko.AutoAddPolicy()) # This script doesn't work for me unless this line is added!
p.connect("server", port=22, username="username", password="password")
stdin, stdout, stderr = p.exec_command("your command")
opt = stdout.readlines()
opt = "".join(opt)
print(opt)
Make sure that paramiko package is installed. Original source of the solution: Source

Like @Alexander-Klyubin suggests, do the move in the repository. It's also going to be much faster, especially if you have a large amount of data to move, because you won't have to transfer all that data over the network again.
svn mv https://username@server/svn/old/ https://username@server/svn/new/
should work just fine
As of 7/29/2019, Github presents users with the instructions for accomplishing this task when a repo is created, offering several options:
create a new repository on the command line
git init
git add README.md
git commit -m "first commit"
git remote add origin https://github.com/user/repo.git
git push -u origin master
push an existing repository from the command line
git remote add origin https://github.com/user/repo.git
git push -u origin master
import code from another repository
press import
button to initialize process.
For the visual learners out there:
for example:
dir1=$(find . -name \*foo\* -type d -maxdepth 1 -print | head -n1)
echo "$dir1"
or (For the better shell solution see Adrian Frühwirth's answer)
for dir1 in *
do
[[ -d "$dir1" && "$dir1" =~ foo ]] && break
dir1= #fix based on comment
done
echo "$dir1"
or
dir1=$(find . -type d -maxdepth 1 -print | grep 'foo' | head -n1)
echo "$dir1"
Edited head -n1 based on @ hek2mgl comment
Next based on @chepner's comments
dir1=$(find . -type d -maxdepth 1 -print | grep -m1 'foo')
or
dir1=$(find . -name \*foo\* -type d -maxdepth 1 -print -quit)

In my case it was because I declared a subclass of a subclass of a UITableView cell in the .h file (the declaration of both subclasses were in the same .h file), but forgot to make an empty implementation of that second subclass in the .m file.
don't forget to implement any subclass of a subclass you declare in the .h file! sounds simple, but easy to forget because Xcode will do this for you if you are working with one class per .h/.m file.
A pair of simple definitions would be:
Forward Proxy: Acting on behalf of a requestor (or service consumer)
Reverse Proxy: Acting on behalf of service/content producer.
Another solution is to make the POST using an hidden form where all the input are of type hidden. The visible form will use input of type "password". The latter form will never be submitted and so the browser can't intercept at all the operation of login.
Are dictionaries ordered in Python 3.6+?
They are insertion ordered[1]. As of Python 3.6, for the CPython implementation of Python, dictionaries remember the order of items inserted. This is considered an implementation detail in Python 3.6; you need to use OrderedDict
if you want insertion ordering that's guaranteed across other implementations of Python (and other ordered behavior[1]).
As of Python 3.7, this is no longer an implementation detail and instead becomes a language feature. From a python-dev message by GvR:
Make it so. "Dict keeps insertion order" is the ruling. Thanks!
This simply means that you can depend on it. Other implementations of Python must also offer an insertion ordered dictionary if they wish to be a conforming implementation of Python 3.7.
How does the Python
3.6
dictionary implementation perform better[2] than the older one while preserving element order?
Essentially, by keeping two arrays.
The first array, dk_entries
, holds the entries (of type PyDictKeyEntry
) for the dictionary in the order that they were inserted. Preserving order is achieved by this being an append only array where new items are always inserted at the end (insertion order).
The second, dk_indices
, holds the indices for the dk_entries
array (that is, values that indicate the position of the corresponding entry in dk_entries
). This array acts as the hash table. When a key is hashed it leads to one of the indices stored in dk_indices
and the corresponding entry is fetched by indexing dk_entries
. Since only indices are kept, the type of this array depends on the overall size of the dictionary (ranging from type int8_t
(1
byte) to int32_t
/int64_t
(4
/8
bytes) on 32
/64
bit builds)
In the previous implementation, a sparse array of type PyDictKeyEntry
and size dk_size
had to be allocated; unfortunately, it also resulted in a lot of empty space since that array was not allowed to be more than 2/3 * dk_size
full for performance reasons. (and the empty space still had PyDictKeyEntry
size!).
This is not the case now since only the required entries are stored (those that have been inserted) and a sparse array of type intX_t
(X
depending on dict size) 2/3 * dk_size
s full is kept. The empty space changed from type PyDictKeyEntry
to intX_t
.
So, obviously, creating a sparse array of type PyDictKeyEntry
is much more memory demanding than a sparse array for storing int
s.
You can see the full conversation on Python-Dev regarding this feature if interested, it is a good read.
In the original proposal made by Raymond Hettinger, a visualization of the data structures used can be seen which captures the gist of the idea.
For example, the dictionary:
d = {'timmy': 'red', 'barry': 'green', 'guido': 'blue'}
is currently stored as [keyhash, key, value]:
entries = [['--', '--', '--'], [-8522787127447073495, 'barry', 'green'], ['--', '--', '--'], ['--', '--', '--'], ['--', '--', '--'], [-9092791511155847987, 'timmy', 'red'], ['--', '--', '--'], [-6480567542315338377, 'guido', 'blue']]
Instead, the data should be organized as follows:
indices = [None, 1, None, None, None, 0, None, 2] entries = [[-9092791511155847987, 'timmy', 'red'], [-8522787127447073495, 'barry', 'green'], [-6480567542315338377, 'guido', 'blue']]
As you can visually now see, in the original proposal, a lot of space is essentially empty to reduce collisions and make look-ups faster. With the new approach, you reduce the memory required by moving the sparseness where it's really required, in the indices.
[1]: I say "insertion ordered" and not "ordered" since, with the existence of OrderedDict, "ordered" suggests further behavior that the dict
object doesn't provide. OrderedDicts are reversible, provide order sensitive methods and, mainly, provide an order-sensive equality tests (==
, !=
). dict
s currently don't offer any of those behaviors/methods.
[2]: The new dictionary implementations performs better memory wise by being designed more compactly; that's the main benefit here. Speed wise, the difference isn't so drastic, there's places where the new dict might introduce slight regressions (key-lookups, for example) while in others (iteration and resizing come to mind) a performance boost should be present.
Overall, the performance of the dictionary, especially in real-life situations, improves due to the compactness introduced.
This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n
and the output of np.add.reduce()
are both scalars, this implies that the problem lies with xm
and ym
, the two of which are simply your x
and y
inputs minus their respective means.
Based on this, my guess is that your x
and y
inputs have different shapes from one another, making them incompatible for element-wise multiplication.
** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.

For a single item enumerable in java it would be Collections.singleton("string");
In c# this is going to be more efficient than a new List:
public class SingleEnumerator<T> : IEnumerable<T>
{
private readonly T m_Value;
public SingleEnumerator(T value)
{
m_Value = value;
}
public IEnumerator<T> GetEnumerator()
{
yield return m_Value;
}
IEnumerator IEnumerable.GetEnumerator()
{
yield return m_Value;
}
}
but is there a simpler way using the framework?

Think of strings as abstract objects, and char arrays as containers. The string can be any size but the container must be at least 1 more than the string length (to hold the null terminator).
C has very little syntactical support for strings. There are no string operators (only char-array and char-pointer operators). You can't assign strings.
But you can call functions to help achieve what you want.
The strncpy()
function could be used here. For maximum safety I suggest following this pattern:
strncpy(p.name, "Jane", 19);
p.name[19] = '\0'; //add null terminator just in case
Also have a look at the strncat()
and memcpy()
functions.
enumerate()
when working on list actually gives the index and the value of the items inside the list.
For example:
l = [1, 2, 3, 4, 5, 6, 7, 8, 9]
for i, j in enumerate(list):
print(i, j)
gives
0 1
1 2
2 3
3 4
4 5
5 6
6 7
7 8
8 9
where the first column denotes the index of the item and 2nd column denotes the items itself.
In a dictionary
enumm = {0: 1, 1: 2, 2: 3, 4: 4, 5: 5, 6: 6, 7: 7}
for i, j in enumerate(enumm):
print(i, j)
it gives the output
0 0
1 1
2 2
3 4
4 5
5 6
6 7
where the first column gives the index of the key:value
pairs and the second column denotes the keys
of the dictionary enumm
.
So if you want the first column to be the keys
and second columns as values
, better try out dict.iteritems()
(Python 2) or dict.items()
(Python 3)
for i, j in enumm.items():
print(i, j)
output
0 1
1 2
2 3
4 4
5 5

attributedPlaceholder = NSAttributedString(string: currentAttributedString.string, attributes: attributes)
}
}
}

@IBInspectable var placeholderColor: UIColor {
get {
return attributedPlaceholder?.attribute(.foregroundColor, at: 0, effectiveRange: nil) as? UIColor ?? .clear
}
set {
guard let attributedPlaceholder = attributedPlaceholder else { return }
let attributes: [NSAttributedStringKey: UIColor] = [.foregroundColor: newValue]
self.attributedPlaceholder = NSAttributedString(string: attributedPlaceholder.string, attributes: attributes)
}
}
}
extension UITextField {
@IBInspectable var placeholderColor: UIColor {

In addition to all the answers above, don't forget the part of the documentation that says
Marker annotation that can be used to define a non-static method as a "setter" or "getter" for a logical property (depending on its signature), or non-static object field to be used (serialized, deserialized) as a logical property.
If you have a non-static
method in your class that is not a conventional getter or setter
then you can make it act like a getter and setter
by using the annotation on it. See the example below
public class Testing {
private Integer id;
private String username;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getUsername() {
return username;
}
public void setUsername(String username) {
this.username = username;
}
public String getIdAndUsername() {
return id + "." + username;
}
public String concatenateIdAndUsername() {
return id + "." + username;
}
}
When the above object is serialized, then response will contain
getUsername()
getId()
getIdAndUsername
* Since the method getIdAndUsername
starts with get
then it's treated as normal getter hence, why you could annotate such with @JsonIgnore
.
If you have noticed the concatenateIdAndUsername
is not returned and that's because it name does not start with get
and if you wish the result of that method to be included in the response then you can use @JsonProperty("...")
and it would be treated as normal getter/setter
as mentioned in the above highlighted documentation.
Assuming you only want to disallow strings that match the regex completely (i.e., mmbla
is okay, but mm
isn't), this is what you want:
^(?!(?:m{2}|t)$).*$
(?!(?:m{2}|t)$)
is a negative lookahead; it says "starting from the current position, the next few characters are not mm
or t
, followed by the end of the string." The start anchor (^
) at the beginning ensures that the lookahead is applied at the beginning of the string. If that succeeds, the .*
goes ahead and consumes the string.
FYI, if you're using Java's matches()
method, you don't really need the the ^
and the final $
, but they don't do any harm. The $
inside the lookahead is required, though.
When you create reversed_arr
you are creating a view into the original array. You can then change the original array, and the view will update to reflect the changes.
Are you re-creating the view more often than you need to? You should be able to do something like this:
arr = np.array(some_sequence)
reversed_arr = arr[::-1]
do_something(arr)
look_at(reversed_arr)
do_something_else(arr)
look_at(reversed_arr)

Here's a way to do it by making use of the way adding one day causes the date to roll over to the next month if necessary, and without messing around with milliseconds. Daylight savings aren't an issue either.
var now = new Date();
var daysOfYear = [];
for (var d = new Date(2012, 0, 1); d <= now; d.setDate(d.getDate() + 1)) {
daysOfYear.push(new Date(d));
}
Note that if you want to store the date, you'll need to make a new one (as above with new Date(d)
), or else you'll end up with every stored date being the final value of d
in the loop.

Its very easy to create procedure in Mysql. Here, in my example I am going to create a procedure which is responsible to fetch all data from student table according to supplied name.
DELIMITER //
CREATE PROCEDURE getStudentInfo(IN s_name VARCHAR(64))
BEGIN
SELECT * FROM student_database.student s where s.sname = s_name;
END//
DELIMITER;
In the above example ,database and table names are student_database and student respectively. Note: Instead of s_name, you can also pass @s_name as global variable.
How to call procedure? Well! its very easy, simply you can call procedure by hitting this command
$mysql> CAll getStudentInfo('pass_required_name');

Although conceptually the same as Asaph's answer (benefiting from the same cross-browser compatibility, even IE6), it is a lot smaller and comes in handy when size is at a premium and/or when it is not needed so often.
function childOf(/*child node*/c, /*parent node*/p){ //returns boolean
while((c=c.parentNode)&&c!==p);
return !!c;
}
..or as one-liner (just 64 chars!):
function childOf(c,p){while((c=c.parentNode)&&c!==p);return !!c}
and jsfiddle here.
Usage:
childOf(child, parent)
returns boolean true
|false
.
Explanation:
while
evaluates as long as the while-condition evaluates to true
.
The &&
(AND) operator returns this boolean true/false after evaluating the left-hand side and the right-hand side, but only if the left-hand side was true (left-hand && right-hand
).
The left-hand side (of &&
) is: (c=c.parentNode)
.
This will first assign the parentNode
of c
to c
and then the AND operator will evaluate the resulting c
as a boolean.
Since parentNode
returns null
if there is no parent left and null
is converted to false
, the while-loop will correctly stop when there are no more parents.
The right-hand side (of &&
) is: c!==p
.
The !==
comparison operator is 'not exactly equal to'. So if the child's parent isn't the parent (you specified) it evaluates to true
, but if the child's parent is the parent then it evaluates to false
.
So if c!==p
evaluates to false, then the &&
operator returns false
as the while-condition and the while-loop stops. (Note there is no need for a while-body and the closing ;
semicolon is required.)
So when the while-loop ends, c
is either a node (not null
) when it found a parent OR it is null
(when the loop ran through to the end without finding a match).
Thus we simply return
that fact (converted as boolean value, instead of the node) with: return !!c;
: the !
(NOT
operator) inverts a boolean value (true
becomes false
and vice-versa).
!c
converts c
(node or null) to a boolean before it can invert that value. So adding a second !
(!!c
) converts this false back to true (which is why a double !!
is often used to 'convert anything to boolean').
Extra:
The function's body/payload is so small that, depending on case (like when it is not used often and appears just once in the code), one could even omit the function (wrapping) and just use the while-loop:
var a=document.getElementById('child'),
b=document.getElementById('parent'),
c;
c=a; while((c=c.parentNode)&&c!==b); //c=!!c;
if(!!c){ //`if(c)` if `c=!!c;` was used after while-loop above
//do stuff
}
instead of:
var a=document.getElementById('child'),
b=document.getElementById('parent'),
c;
function childOf(c,p){while((c=c.parentNode)&&c!==p);return !!c}
c=childOf(a, b);
if(c){
//do stuff
}
I did the following experiment at home:
let's compare how 2 computers compile the same android application in eclipse. Here are the competitors:
"the monster" - pentinum i7 - 16 gig RAM - solid state hard drive
"peabody" - pentinum i3 - 4 gig RAM
The results: when I compiled the same application in eclipse, the monster and peabody took exactly the same amount of time to bring up the emulator to the point where you have to slide the button to run the app: 1 minute 12 seconds.
After that point, the monster executed the app 30-40 seconds faster than peabody.
The monster costs about $500 more than the peabody. So the question is, is it really worth it? In my opinion, No. I can wait the extra 30-40 seconds
There are many different versions of mail around. When you go beyond mail -s subject to1@address1 to2@address2
With some mailx implementations, e.g. from mailutils on Ubuntu or Debian's bsd-mailx, it's easy, because there's an option for that.
mailx -a 'Content-Type: text/html' -s "Subject" to@address <test.html
With the Heirloom mailx, there's no convenient way. One possibility to insert arbitrary headers is to set editheaders=1 and use an external editor (which can be a script).
## Prepare a temporary script that will serve as an editor.
## This script will be passed to ed.
temp_script=$(mktemp)
cat <<'EOF' >>"$temp_script"
1a
Content-Type: text/html
.
$r test.html
w
q
EOF
## Call mailx, and tell it to invoke the editor script
EDITOR="ed -s $temp_script" heirloom-mailx -S editheaders=1 -s "Subject" to@address <<EOF
~e
.
EOF
rm -f "$temp_script"
With a general POSIX mailx, I don't know how to get at headers.
If you're going to use any mail or mailx, keep in mind that
This isn't portable even within a given Linux distribution. For example, both Ubuntu and Debian have several alternatives for mail and mailx.
When composing a message, mail and mailx treats lines beginning with ~ as commands. If you pipe text into mail, you need to arrange for this text not to contain lines beginning with ~.
If you're going to install software anyway, you might as well install something more predictable than mail/Mail/mailx. For example, mutt. With Mutt, you can supply most headers in the input with the -H option, but not Content-Type, which needs to be set via a mutt option.
mutt -e 'set content_type=text/html' -s 'hello' 'to@address' <test.html
Or you can invoke sendmail directly. There are several versions of sendmail out there, but they all support sendmail -t to send a mail in the simplest fashion, reading the list of recipients from the mail. (I think they don't all support Bcc:.) On most systems, sendmail isn't in the usual $PATH, it's in /usr/sbin or /usr/lib.
cat <<'EOF' - test.html | /usr/sbin/sendmail -t
To: to@address

First of all, my response to the question you've originally asked
Q: How do I discover if a variable is defined at a point in my code?
A: Read up in the source file until you see a line where that variable is defined.
But further, you've given a code example that there are various permutations of that are quite pythonic. You're after a way to scan a sequence for elements that match a condition, so here are some solutions:
def findFirstMatch(sequence):
for value in sequence:
if matchCondition(value):
return value
raise LookupError("Could not find match in sequence")
Clearly in this example you could replace the raise
with a return None
depending on what you wanted to achieve.
If you wanted everything that matched the condition you could do this:
def findAllMatches(sequence):
matches = []
for value in sequence:
if matchCondition(value):
matches.append(value)
return matches
There is another way of doing this with yield
that I won't bother showing you, because it's quite complicated in the way that it works.
Further, there is a one line way of achieving this:
all_matches = [value for value in sequence if matchCondition(value)]

Using Firefox, I went to Options -> Advanced -> Certificates -> View Certificates -> Servers
, found there the selfsigned host, selected it and using Export
button I got exactly the same file, as created using openssl
.
Note: I was a bit surprised, there is no name of the authority visibly mentioned. This is fine.
Previous steps shall result in having the certificate in some file. It does not matter, what file it is as long as it is visible to your git when accessing that domain. I used ~/git-certs/cert.pem
Note: If you need more trusted selfsigned certificates, put them into the same file:
-----BEGIN CERTIFICATE-----
MIIDnzCCAocCBE/xnXAwDQYJKoZIhvcNAQEFBQAwgZMxCzAJBgNVBAYTAkRFMRUw
...........
/27/jIdVQIKvHok2P/u9tvTUQA==
-----END CERTIFICATE-----
-----BEGIN CERTIFICATE-----
AnOtHeRtRuStEdCeRtIfIcAtEgOeShErExxxxxxxxxxxxxxxxxxxxxxxxxxxxxxw
...........
/27/jIdVQIKvHok2P/u9tvTUQA==
-----END CERTIFICATE-----
This shall work (but I tested it only with single certificate).
$ git config --global http.sslCAInfo /home/javl/git-certs/cert.pem
You may also try to do that system wide, using --system
instead of --global
.
And test it: You shall now be able communicating with your server without resorting to:
$ git config --global http.sslVerify false #NO NEED TO USE THIS
If you already set your git to ignorance of ssl certificates, unset it:
$ git config --global --unset http.sslVerify
and you may also check, that you did it all correctly, without spelling errors:
$ git config --global --list
what should list all variables, you have set globally. (I mispelled http to htt).
SpringBoot is actually pre configured that reduced boiler configuration and providing easiest or quick way to start your application.
SpringBoot take the headache of configuration from developer to it's own self rather than Spring.
Implicitly SpringBoot is based on Spring framework concept like bean, controller , services, jpa etc.
You can say that SpringBoot is a wrapper of Spring.
In SpringBoot by default port of Server is 8080 but if you want to change then go to your application.properties and write
server.port = 8084
Use This as the solution
This worked for me perfectly..
<div align="center">

It is used to stop the propagation of the event. You see when you have two elements both with a click event handler (for example)
-----------------------------------
| element1 |
| ------------------------- |
| |element2 | |
| ------------------------- |
| |
-----------------------------------
If you click on the inner element (element2) it will trigger a click event in both elements: 1 and 2. It is called "Event bubbling". If you want to handle the event in element2 only, then the event handler has to return false to stop the event propagation.
Another example will be the link onclick handler. If you want to stop a link form working. You can add an onclick handler and return false. To stop the event from propagating to the default handler.
try this
$('#div_id').animate({scrollTop:0}, '500', 'swing');
HashMap compatible Pair class:

public int hashCode() {
int hashFirst = first != null ? first.hashCode() : 0;
int hashSecond = second != null ? second.hashCode() : 0;
return (hashFirst + hashSecond) * hashSecond + hashFirst;
}
public boolean equals(Object other) {
if (other instanceof Pair) {

To meet these criteria: modify original list in situ, no list copies, only one pass, works, a traditional solution is to iterate backwards:
for i in xrange(len(somelist) - 1, -1, -1):
element = somelist[i]
do_action(element)
if check(element):
del somelist[i]
Bonus: Doesn't do len(somelist)
on each iteration. Works on any version of Python (at least as far back as 1.5.2) ... s/xrange/range/ for 3.X.
Update: If you want to iterate forwards, it's possible, just trickier and uglier:
i = 0
n = len(somelist)
while i < n:
element = somelist[i]
do_action(element)
if check(element):
del somelist[i]
n = n - 1
else:
i = i + 1
This post has helped me a lot, and after a few iterations, this is what we use.
The idea is to post log messages and errors to HTML, for example if you need to debug JS and don't have access to the console.
You do need to change 'console.log' with 'logThis', as it is not recommended to change native functionality.
What you'll get:
function logThis(message) {
// if we pass an Error object, message.stack will have all the details, otherwise give us a string
if (typeof message === 'object') {
message = message.stack || objToString(message);
}
console.log(message);
// create the message line with current time
var today = new Date();
var date = today.getFullYear() + '-' + (today.getMonth() + 1) + '-' + today.getDate();
var time = today.getHours() + ':' + today.getMinutes() + ':' + today.getSeconds();
var dateTime = date + ' ' + time + ' ';
//insert line
document.getElementById('logger').insertAdjacentHTML('afterbegin', dateTime + message + '<br>');
}
function objToString(obj) {
var str = 'Object: ';
for (var p in obj) {
if (obj.hasOwnProperty(p)) {
str += p + '::' + obj[p] + ',\n';
}
}
return str;
}
const object1 = {
a: 'somestring',
b: 42,
c: false
};
logThis(object1)
logThis('And all the roads we have to walk are winding, And all the lights that lead us there are blinding')

Thanks this answer too, JSON.stringify() didn't work for this.
The main()
method is the entry point for a Java application. run()
is typically used for new threads or tasks.
Where have you been writing a run()
method, what kind of application are you writing (e.g. Swing, AWT, console etc) and what's your development environment?
If you are planning to use the code in a production web application code,
using any web framework like Django/Flask, use projects like envparse, using it you can read the value as your defined type.
from envparse import env
# will read WHITE_LIST=hello,world,hi to white_list = ["hello", "world", "hi"]
white_list = env.list("WHITE_LIST", default=[])
# Perfect for reading boolean
DEBUG = env.bool("DEBUG", default=False)
NOTE: kennethreitz's autoenv is a recommended tool for making project specific environment variables, please note that those who are using autoenv
please keep the .env
file private (inaccessible to public)
Another nifty way is:
DATEADD(dd, 0, DATEDIFF(dd, 0, [YourDate]))
Which gets the number of days from DAY 0 to YourDate and the adds it to DAY 0 to set the baseline again. This method (or "derivatives" hereof) can be used for a bunch of other date manipulation.
Edit - other date calculations:
First Day of Month:
DATEADD(mm, DATEDIFF(mm, 0, getdate()), 0)
First Day of the Year:
DATEADD(yy, DATEDIFF(yy, 0, getdate()), 0)
First Day of the Quarter:
DATEADD(qq, DATEDIFF(qq, 0, getdate()), 0)
Last Day of Prior Month:
DATEADD(ms, -3, DATEADD(mm, DATEDIFF(mm, 0, getdate()), 0))
Last Day of Current Month:
DATEADD(ms, -3, DATEADD(mm, DATEDIFF(m, 0, getdate()) + 1, 0))
Last Day of Current Year:
DATEADD(ms, -3, DATEADD(yy, DATEDIFF(yy, 0, getdate()) + 1, 0))
First Monday of the Month:
DATEADD(wk, DATEDIFF(wk, 0, DATEADD(dd, 6 - DATEPART(day, getdate()), getdate())), 0)
Edit: True, Joe, it does not add it to DAY 0, it adds 0 (days) to the number of days which basically just converts it back to a datetime.
Thank you for your responses. Turns out my problem was a database issue with duplicate entries, not with my logic. A quick table sync fixed that and the SUM feature worked as expected. This is all still useful knowledge for the SUM feature and is worth reading if you are having trouble using it.
Because the dot is inside character class (square brackets []
).
Take a look at http://www.regular-expressions.info/reference.html, it says (under char class section):
Any character except ^-]\ add that character to the possible matches for the character class.
Inside bootstrap.css search the next code:
.fixed-table-body {
overflow-x: auto;
overflow-y: auto;
height: 100%;
}
...and update with this:
.fixed-table-body {
overflow-x: visible;
overflow-y: visible;
height: 100%;
}
If the string contains Unicode data (strictly speaking, non-BMP characters) the other methods that have been posted will corrupt it, because you cannot swap the order of high and low surrogate code units when reversing the string. (More information about this can be found on my blog.)
The following code sample will correctly reverse a string that contains non-BMP characters, e.g., "\U00010380\U00010381" (Ugaritic Letter Alpa, Ugaritic Letter Beta).
public static string Reverse(this string input)
{
if (input == null)
throw new ArgumentNullException("input");
// allocate a buffer to hold the output
char[] output = new char[input.Length];
for (int outputIndex = 0, inputIndex = input.Length - 1; outputIndex < input.Length; outputIndex++, inputIndex--)
{
// check for surrogate pair
if (input[inputIndex] >= 0xDC00 && input[inputIndex] <= 0xDFFF &&
inputIndex > 0 && input[inputIndex - 1] >= 0xD800 && input[inputIndex - 1] <= 0xDBFF)
{
// preserve the order of the surrogate pair code units
output[outputIndex + 1] = input[inputIndex];
output[outputIndex] = input[inputIndex - 1];
outputIndex++;
inputIndex--;
}
else
{
output[outputIndex] = input[inputIndex];
}
}
return new string(output);
}

Since I cannot comment yet, I'm posting an enhanced answer based on @tiago-peres-frança fantastic solution (thanks!). His code does not make directory in a case where only the last directory is missing in the path, e.g. the input is "C:/test/abc" and "C:/test" already exists. Here is a snippet that works:
function mkdirp(filepath) {
var dirname = path.dirname(filepath);
if (!fs.existsSync(dirname)) {
mkdirp(dirname);
}
fs.mkdirSync(filepath);
}
I've personally never seen .cc
in any project that I've worked on, but in all technicality the compiler won't care.
Who will care is the developers working on your source, so my rule of thumb is to go with what your team is comfortable with. If your "team" is the open source community, go with something very common, of which .cpp
seems to be the favourite.
Example of how to use Python REPL interpreter with function that accepts parameters.
>>> import timeit
>>> def naive_func(x):
... a = 0
... for i in range(a):
... a += i
... return a
>>> def wrapper(func, *args, **kwargs):
... def wrapper():
... return func(*args, **kwargs)
... return wrapper
>>> wrapped = wrapper(naive_func, 1_000)
>>> timeit.timeit(wrapped, number=1_000_000)

If you are using AdonisJS and have mixed IDs such as ABC-202, ABC-201..., you can combine raw queries with Query Builder and implement the solution above (https://stackoverflow.com/a/25061144/4040835) as follows:
const sortField =
'membership_id'
const sortDirection =
'asc'
const subquery = UserProfile.query()
.select(
'user_profiles.id',
'user_profiles.user_id',
'user_profiles.membership_id',
'user_profiles.first_name',
'user_profiles.middle_name',
'user_profiles.last_name',
'user_profiles.mobile_number',
'countries.citizenship',
'states.name as state_of_origin',
'user_profiles.gender',
'user_profiles.created_at',
'user_profiles.updated_at'
)
.leftJoin(
'users',
'user_profiles.user_id',
'users.id'
)
.leftJoin(
'countries',
'user_profiles.nationality',
'countries.id'
)
.leftJoin(
'states',
'user_profiles.state_of_origin',
'states.id'
)
.orderByRaw(
`SUBSTRING(:sortField:,3,15)*1 ${sortDirection}`,
{
sortField: sortField,
}
)
.paginate(
page,
per_page
)
NOTES:
In this line: SUBSTRING(:sortField:,3,15)*1 ${sortDirection}
,
Ref 1: You can read more about parameter bindings in raw queries here: https://knexjs.org/#Raw-Bindings Ref 2: Adonis Raw Queries: https://adonisjs.com/docs/4.1/query-builder#_raw_queries
Do you mean like this?
var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);
To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll()
to accomplish this:
HTML
<div class="abc"></div>
<div class="abc"></div>
JS
var abcElements = document.querySelectorAll('.abc');
// Set their ids
for (var i = 0; i < abcElements.length; i++)
abcElements[i].id = 'abc-' + i;
This will assign the ID 'abc-<index number>'
to each element. So it would come out like this:
<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>
To create an element and assign an id
we can use document.createElement()
and then appendChild()
.
var div = document.createElement('div');
div.id = 'hello1';
var body = document.querySelector('body');
body.appendChild(div);
Update
You can set the id
on your element like this if your script is in your HTML file.
<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">
<script type="text/javascript">
var s = document.getElementsByClassName('assign-me')[0];
s.id = btoa({{str(produit["avt"]["fto"])}});
</script>
Your requirements still aren't 100% clear though.
I got this error and fixed by appending the directory path in the loop. script not in the same directory as the files. dr1 ="~/test" directory variable
fileop=open(dr1+"/"+fil,"r")
You can mock member variables of a Mockito Mock with ReflectionTestUtils
ReflectionTestUtils.setField(yourMock, "memberFieldName", value);
Using the request module solved the issue.
// Include the request library for Node.js
var request = require('request');
// Basic Authentication credentials
var username = "vinod";
var password = "12345";
var authenticationHeader = "Basic " + new Buffer(username + ":" + password).toString("base64");
request(
{
url : "https://133-70-97-54-43.sample.com/feedSample/Query_Status_View/Query_Status/Output1?STATUS=Joined%20school",
headers : { "Authorization" : authenticationHeader }
},
function (error, response, body) {
console.log(body); } );
We can define maximum pool size in following way:
<pool>
<min-pool-size>5</min-pool-size>
<max-pool-size>200</max-pool-size>
<prefill>true</prefill>
<use-strict-min>true</use-strict-min>
<flush-strategy>IdleConnections</flush-strategy>
</pool>
Shafik Yaghmour's answer correctly explains why the lambda cannot be passed as a function pointer if it has a capture. I'd like to show two simple fixes for the problem.
Use std::function
instead of raw function pointers.
This is a very clean solution. Note however that it includes some additional overhead for the type erasure (probably a virtual function call).
#include <functional>
#include <utility>
struct Decide
{
using DecisionFn = std::function<bool()>;
Decide(DecisionFn dec) : dec_ {std::move(dec)} {}
DecisionFn dec_;
};
int
main()
{
int x = 5;
Decide greaterThanThree { [x](){ return x > 3; } };
}
Use a lambda expression that doesn't capture anything.
Since your predicate is really just a boolean constant, the following would quickly work around the current issue. See this answer for a good explanation why and how this is working.
// Your 'Decide' class as in your post.
int
main()
{
int x = 5;
Decide greaterThanThree {
(x > 3) ? [](){ return true; } : [](){ return false; }
};
}
I suggest you also add separate checkboxes or a textfield for the special flags. That way it is clear that the user does not need to add any //
's. In the case of a replace, provide two textfields. This will make your life a lot easier.
Why? Because otherwise some users will add //
's while other will not. And some will make a syntax error. Then, after you stripped the //
's, you may end up with a syntactically valid regex that is nothing like what the user intended, leading to strange behaviour (from the user's perspective).

for cs of this file :
public partial class MessageboxNew : Window
{
public MessageboxNew()
{
InitializeComponent();
//second time show error solved
if (Application.Current == null) new Application();
Application.Current.ShutdownMode = ShutdownMode.OnExplicitShutdown;
}
private void ButtonBase_OnClick(object sender, RoutedEventArgs e)
{
DialogResult = true;
}
private void cancel_Click(object sender, RoutedEventArgs e)
{
DialogResult = false;
}
private void FrameworkElement_OnLoaded(object sender, RoutedEventArgs e)
{
this.MouseDown += delegate { DragMove(); };
}
}
then create a class to use this :
public class Mk_MessageBox
{
public static bool? Show(string title, string text)
{
MessageboxNew msg = new MessageboxNew
{
TitleBar = {Text = title},
Textbar = {Text = text}
};
msg.noBtn.Focus();
return msg.ShowDialog();
}
}
now you can create your message box like this:
var result = Mk_MessageBox.Show("Remove Alert", "This is gonna remove directory from host! Are you sure?");
if (result == true)
{
// whatever
}
copy this to App.xaml inside

Regards to your question... counting one Field? I decided to make it a question, but I hope it helps...
Say I have the following DataFrame
import numpy as np
import pandas as pd
df = pd.DataFrame(np.random.normal(0, 1, (5, 2)), columns=["A", "B"])
You could count a single column by
df.A.count()
#or
df['A'].count()
both evaluate to 5.
The cool thing (or one of many w.r.t. pandas
) is that if you have NA
values, count takes that into consideration.
So if I did
df['A'][1::2] = np.NAN
df.count()
The result would be
A 3
B 5
SQL doesn't return any ordering by default because it's faster this way. It doesn't have to go through your data first and then decide what to do.
You need to add an order by clause, and probably order by which ever ID you expect. (There's a duplicate of names, thus I'd assume you want One.ID)
select * From one
inner join two
ON one.one_name = two.one_name
ORDER BY one.ID

On unix and linux there is the file
command to guess file types. There's even a windows port.
From the man page:
File tests each argument in an attempt to classify it. There are three sets of tests, performed in this order: filesystem tests, magic number tests, and language tests. The first test that succeeds causes the file type to be printed.
You would need to run the file
command with the subprocess
module and then parse the results to figure out an extension.

A more distilled quick answer:
git add -A
git add .
git add -u
net use \\<host> /delete
should work, but many times it does not.
net stop workstation
as @DaveInCaz offered works in such cases.
I have some why and hows I couldn't fit into a comment.
It's not enough to restart the Workstation service (e.g. from services.msc console)
The service probably needs to be disabled for some short period of time. If you do this restart from a script, might be better to add a 1 second delay.
In cases when net use \\<host> /delete
does not work because another program is still using that share, you can identify such program and remove the blocking handle without closing it. Use Sysinternals Process Explorer, press Ctrl+F for search and enter the name of host machine owning such share. Click on each result, program window behind search dialog jumps to found program's handle. Right click that handle and select Close Handle. (or just close such program if you can) This works only in regular cases where there really is a program blocking the share disconnect. Not in those weird cases when it's blocked for no reason.
elevated account has it's own environment. This brings some unexpected behavior.
If you do net use
command in an elevated cmd/PS console, it will not affect which user will Windows Explorer use to access the share.
And also other way around, if you run a program from the share and the program will ask and get elevated access, that program will loose connection to that share and any files it might need to run. You need to run net use
from elevated cmd/PS to create an elevated share connection to that share.
Removing Recent folders from Quick Access in Windows Explorer (top of left panel) might help in certain cases.
If the Host you are connecting to offers different access levels based on user, and/or has a Guest user (anonymous) share access, this is a situation you might often run into.
When you access a share using your username, folder inside such share might get assigned to Quick Access panel as a Recent item. When you open Windows Explorer after restart, Recent items inside Quick Access will be checked and a connection will be made to the Host machine and will stay open in form of a MUP. If your share accepts both authorized and anonymous connections, just opening Windows Explorer will create anonymous connection and when you click on a share which needs authorization, you will not get credential dialog but an error.

The answer of Pardeep Jain can be useful for static data, but what if we have an array in JSON?
For example, we have i values and get the value of id field
alert(obj[i].id); //works!
But what if we need key with spaces?
In this case, the following construction can help (without point between [] blocks):
alert(obj[i]["No. of interfaces"]); //works too!
Try this:
export PATH=/home/your_username/anaconda3/bin:$PATH
in ~/.bashrc
Then source ~/.bashrc
This works for me for the same problem.
(See the history on this answer to get the more elaborate text, but I now think it's easier for the reader to see real command lines).
Common files shared by all below commands
$ cat a.cpp

int main() {
return a;
}
$ cat b.cpp

int a = b;
$ cat d.cpp

$ g++ -c b.cpp -o b.o
$ ar cr libb.a b.o
$ g++ -c d.cpp -o d.o
$ ar cr libd.a d.o
$ g++ -L. -ld -lb a.cpp # wrong order

$ g++ a.cpp -L. -ld -lb # wrong order
$ g++ a.cpp -L. -lb -ld # right order
The linker searches from left to right, and notes unresolved symbols as it goes. If a library resolves the symbol, it takes the object files of that library to resolve the symbol (b.o out of libb.a in this case).
Dependencies of static libraries against each other work the same - the library that needs symbols must be first, then the library that resolves the symbol.
If a static library depends on another library, but the other library again depends on the former library, there is a cycle. You can resolve this by enclosing the cyclically dependent libraries by -(
and -)
, such as -( -la -lb -)
(you may need to escape the parens, such as -\(
and -\)
). The linker then searches those enclosed lib multiple times to ensure cycling dependencies are resolved. Alternatively, you can specify the libraries multiple times, so each is before one another: -la -lb -la
.
$ export LD_LIBRARY_PATH=. # not needed if libs go to /usr/lib etc
$ g++ -fpic -shared d.cpp -o libd.so
$ g++ -fpic -shared b.cpp -L. -ld -o libb.so # specifies its dependency!
$ g++ -L. -lb a.cpp # wrong order (works on some distributions)
$ g++ -Wl,--as-needed -L. -lb a.cpp # wrong order
$ g++ -Wl,--as-needed a.cpp -L. -lb # right order
It's the same here - the libraries must follow the object files of the program. The difference here compared with static libraries is that you need not care about the dependencies of the libraries against each other, because dynamic libraries sort out their dependencies themselves.
Some recent distributions apparently default to using the --as-needed
linker flag, which enforces that the program's object files come before the dynamic libraries. If that flag is passed, the linker will not link to libraries that are not actually needed by the executable (and it detects this from left to right). My recent archlinux distribution doesn't use this flag by default, so it didn't give an error for not following the correct order.
It is not correct to omit the dependency of b.so
against d.so
when creating the former. You will be required to specify the library when linking a
then, but a
doesn't really need the integer b
itself, so it should not be made to care about b
's own dependencies.
Here is an example of the implications if you miss specifying the dependencies for libb.so
$ export LD_LIBRARY_PATH=. # not needed if libs go to /usr/lib etc
$ g++ -fpic -shared d.cpp -o libd.so
$ g++ -fpic -shared b.cpp -o libb.so # wrong (but links)
$ g++ -L. -lb a.cpp # wrong, as above
$ g++ -Wl,--as-needed -L. -lb a.cpp # wrong, as above
$ g++ a.cpp -L. -lb # wrong, missing libd.so
$ g++ a.cpp -L. -ld -lb # wrong order (works on some distributions)
$ g++ -Wl,--as-needed a.cpp -L. -ld -lb # wrong order (like static libs)
$ g++ -Wl,--as-needed a.cpp -L. -lb -ld # "right"
If you now look into what dependencies the binary has, you note the binary itself depends also on libd
, not just libb
as it should. The binary will need to be relinked if libb
later depends on another library, if you do it this way. And if someone else loads libb
using dlopen
at runtime (think of loading plugins dynamically), the call will fail as well. So the "right"
really should be a wrong
as well.
When using SQL Express, you need to specify \SQLExpress instance in your connection string:
string str = "Data Source=HARIHARAN-PC\\SQLEXPRESS;Initial Catalog=master;Integrated Security=True" ;
If you are using a data source, here's another way to do it without code behind.
Note the following key points:
ListItem
of Value="0"
is on the source page, not added in codeListItem
in the source will be overwritten if you don't include
AppendDataBoundItems="true"
in the DropDownList
InitialValue="0"
tells the validator that this is the value that
should fire that validator (as pointed out in other answers)Example:
<asp:DropDownList ID="ddlType" runat="server" DataSourceID="sdsType"
DataValueField="ID" DataTextField="Name" AppendDataBoundItems="true">
<asp:ListItem Value="0" Text="--Please Select--" Selected="True"></asp:ListItem>
</asp:DropDownList>
<asp:RequiredFieldValidator ID="rfvType" runat="server" ControlToValidate="ddlType"
InitialValue="0" ErrorMessage="Type required"></asp:RequiredFieldValidator>
<asp:SqlDataSource ID="sdsType" runat="server"
ConnectionString='<%$ ConnectionStrings:TESTConnectionString %>'
SelectCommand="SELECT ID, Name FROM Type"></asp:SqlDataSource>
Another way to get only the numbers in a regex string is as shown below:
$output = preg_replace("/\D+/", "", $input);
The simple way to solve the problem is to use ComparisonChain from Guava http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/collect/ComparisonChain.html
private static Comparator<String> stringAlphabeticalComparator = new Comparator<String>() {
public int compare(String str1, String str2) {
return ComparisonChain.start().
compare(str1,str2, String.CASE_INSENSITIVE_ORDER).
compare(str1,str2).
result();
}
};
Collections.sort(list, stringAlphabeticalComparator);
The first comparator from the chain will sort strings according to the case insensitive order, and the second comparator will sort strings according to the case insensitive order. As excepted strings appear in the result according to the alphabetical order:
"AA","Aa","aa","Development","development"
One additional suggestion to be explicit. It seems best to go from specific to general down the stack of errors to get the desired error to be caught, so the specific ones don't get masked by the general one.

'Effectively final' is a variable which would not give compiler error if it were to be appended by 'final'
From a article by 'Brian Goetz',
Informally, a local variable is effectively final if its initial value is never changed -- in other words, declaring it final would not cause a compilation failure.
The above answer seems good. But another way of doing this is adding the auto commit option along with the db connect. This automatically commits every other operations performed in the db, avoiding the use of mentioning sql.commit()
every time.
mydb = MySQLdb.connect(host='localhost',
user='root',
passwd='',
db='mydb',autocommit=true)

NSCalendar *cal = [NSCalendar currentCalendar];
NSDate *tomorrow = [cal dateByAddingUnit:NSCalendarUnitDay

Basically in java, continue is a statement. So continue statement is normally used with the loops to skip the current iteration.
For how and when it is used in java, refer link below. It has got explanation with example.

Starting from Xcode 8, you can use the class property attribute as answered by Berbie.
However, in the implementation, you need to define both class getter and setter for the class property using a static variable in lieu of an iVar.
Sample.h
@interface Sample: NSObject
@property (class, retain) Sample *sharedSample;
@end
Sample.m
@implementation Sample
static Sample *_sharedSample;
+ ( Sample *)sharedSample {
if (_sharedSample==nil) {
[Sample setSharedSample:_sharedSample];
}
return _sharedSample;
}
+ (void)setSharedSample:(Sample *)sample {
_sharedSample = [[Sample alloc]init];
}

I really question the value of this, though. You're stated goal is to make the value shorter, which it will, but that isn't a goal in itself. You really mean either make it easier to remember or easier to type.
If you mean easier to remember, then you're taking a step backwards. We know it's still the same size, just encoded differently. But your users won't know that the letters are restricted to 'A-F', and so the ID will occupy the same conceptual space for them as if the letter 'A-Z' were allowed. So instead of being like memorizing a telephone number, it's more like memorizing a GUID (of equivalent length).
If you mean typing, instead of being able to use the keypad the user now must use the main part of the keyboard. It's likely to be more difficult to type, because it won't be a word their fingers recognize.
A much better option is to actually let them pick a real username.
With this matcher function you can get desirable behavior without component re-rendering. When url.length equals to 0, there's no optional parameters, with url.length equals to 1, there's 1 optional parameter. id - is the name of optional parameter.
const routes: Routes = [
{
matcher: (segments) => {
if (segments.length <= 1) {
return {
consumed: segments,
posParams: {
id: new UrlSegment(segments[0]?.path || '', {}),
},
};
}
return null;
},
pathMatch: 'prefix',
component: UserComponent,
}]
For other language use day of week to recognize day name
For example for Persian use below code
$dayName = getDayName(date('w', strtotime('2019-11-14')));
function getDayName($dayOfWeek) {
switch ($dayOfWeek){
case 6:
return '????';
case 0:
return '?? ????';
case 1:
return '?? ????';
case 2:
return '?? ????';
case 3:
return '???? ????';
case 4:
return '??? ????';
case 5:
return '????';
default:
return '';
}
}

Here is a small demo
Identifiers are used for class names, method names, and variable names. An identifiermay be any descriptive sequence of uppercase and lowercase letters, numbers, or theunderscore and dollar-sign characters. They must not begin with a number, lest they beconfused with a numeric literal. Again, Java is case-sensitive, so VALUE is a differentidentifier than Value. Some examples of valid identifiers are:
AvgTemp ,count a4 ,$test ,this_is_ok
Invalid variable names include:
2count, high-temp, Not/ok
Quoted from monsur,
The Access-Control-Allow-Headers header does not allow wildcards. It must be an exact match: http://www.w3.org/TR/cors/#access-control-allow-headers-response-header.
So here is my php solution.
if ($_SERVER['REQUEST_METHOD'] == 'OPTIONS') {
$headers=getallheaders();
@$ACRH=$headers["Access-Control-Request-Headers"];
header("Access-Control-Allow-Headers: $ACRH");
}
It does work indeed. Issue was with my less compiler. It was compiled in to:
.container {
min-height: calc(-51vh);
}
Fixed with the following code in less file:
.container {
min-height: calc(~"100vh - 150px");
}

Answering the question "given two lists, find all possible permutations of pairs of one item from each list" and using basic Python functionality (i.e., without itertools) and, hence, making it easy to replicate for other programming languages:
def rec(a, b, ll, size):
ret = []
for i,e in enumerate(a):
for j,f in enumerate(b):
l = [e+f]
new_l = rec(a[i+1:], b[:j]+b[j+1:], ll, size)
if not new_l:
ret.append(l)
for k in new_l:
l_k = l + k
ret.append(l_k)
if len(l_k) == size:
ll.append(l_k)
return ret
a = ['a','b','c']
b = ['1','2']
ll = []
rec(a,b,ll, min(len(a),len(b)))
print(ll)
Returns
[['a1', 'b2'], ['a1', 'c2'], ['a2', 'b1'], ['a2', 'c1'], ['b1', 'c2'], ['b2', 'c1']]

The objects in the std::set
are stored as const StudentT
. So when you try to call getId()
with the const
object the compiler detects a problem, mainly you're calling a non-const member function on const object which is not allowed because non-const member functions make NO PROMISE not to modify the object; so the compiler is going to make a safe assumption that getId()
might attempt to modify the object but at the same time, it also notices that the object is const; so any attempt to modify the const object should be an error. Hence compiler generates an error message.
The solution is simple: make the functions const as:
int getId() const {
return id;
}
string getName() const {
return name;
}
This is necessary because now you can call getId()
and getName()
on const objects as:
void f(const StudentT & s)
{
cout << s.getId(); //now okay, but error with your versions
cout << s.getName(); //now okay, but error with your versions
}
As a sidenote, you should implement operator<
as :
inline bool operator< (const StudentT & s1, const StudentT & s2)
{
return s1.getId() < s2.getId();
}
Note parameters are now const
reference.
Construct a Random object at application startup:
Random random = new Random();
Then use Random.nextInt(int):
int randomNumber = random.nextInt(max + 1 - min) + min;
Note that the both lower and upper limits are inclusive.
Here's an alternate
req.hostname
Read about it in the Express Docs.
I was able to get mine working using the following Client Credentials:
Authorized JavaScript origins
http://localhost
Authorized redirect URIs
http://localhost:8090/oauth2callback
Note: I used port 8090 instead of 8080, but that doesn't matter as long as your python script uses the same port as your client_secret.json file.
Reference: Python Quickstart
var yearsToAdd = 5;
var current = new Date().toISOString().split('T')[0];
var addedYears = Number(this.minDate.split('-')[0]) + yearsToAdd + '-12-31';
file__IO = input('\nEnter file name here to analize with path:: ')
with open(file__IO, 'r') as f:
data = f.read()
line = data.splitlines()
words = data.split()
spaces = data.split(" ")
charc = (len(data) - len(spaces))
print('\n Line number ::', len(line), '\n Words number ::', len(words), '\n Spaces ::', len(spaces), '\n Charecters ::', (len(data)-len(spaces)))
I tried this code & it works as expected.
You can only use aggregates for comparison in the HAVING clause:
GROUP BY ...
HAVING SUM(cash) > 500
The HAVING
clause requires you to define a GROUP BY clause.
To get the first row where the sum of all the previous cash is greater than a certain value, use:
SELECT y.id, y.cash
FROM (SELECT t.id,
t.cash,
(SELECT SUM(x.cash)
FROM TABLE x
WHERE x.id <= t.id) AS running_total
FROM TABLE t
ORDER BY t.id) y
WHERE y.running_total > 500
ORDER BY y.id
LIMIT 1
Because the aggregate function occurs in a subquery, the column alias for it can be referenced in the WHERE clause.

How about:
ACell.ListObject.DataBodyRange.Rows.Delete
That will keep your table structure and headings, but clear all the data and rows.
EDIT: I'm going to just modify a section of my answer from your previous post, as it does mostly what you want. This leaves just one row:
With loSource
.Range.AutoFilter
.DataBodyRange.Offset(1).Resize(.DataBodyRange.Rows.Count - 1, .DataBodyRange.Columns.Count).Rows.Delete
.DataBodyRange.Rows(1).Specialcells(xlCellTypeConstants).ClearContents
End With
If you want to leave all the rows intact with their formulas and whatnot, just do:
With loSource
.Range.AutoFilter
.DataBodyRange.Specialcells(xlCellTypeConstants).ClearContents
End With
Which is close to what @Readify suggested, except it won't clear formulas.
read from assets html file
ViewGroup webGroup;
String content = readContent("content/ganji.html");
final WebView webView = new WebView(this);
webView.loadDataWithBaseURL(null, content, "text/html", "UTF-8", null);
webGroup.addView(webView);
So here is the controller code.
public IActionResult AddURLTest()
{
return ViewComponent("AddURL");
}
You can load it using JQuery load method.
$(document).ready (function(){
$("#LoadSignIn").click(function(){
$('#UserControl').load("/Home/AddURLTest");
});
});

JRE
JRE is an acronym for Java Runtime Environment.It is used to provide runtime environment.It is the implementation of JVM.It physically exists.It contains set of libraries + other files that JVM uses at runtime.
JDK
JDK is an acronym for Java Development Kit.It physically exists.It contains JRE + development tools.
Link :- http://www.javatpoint.com/difference-between-jdk-jre-and-jvm
Usually, when you only care about running Java programs on your browser or computer you will only install JRE. It's all you need. On the other hand, if you are planning to do some Java programming, you will also need JDK.
In my case I was using more than two variables, and this worked for me better:
cor(x = as.matrix(tbl), method = "pearson", use = "pairwise.complete.obs")
However:
If use has the value "pairwise.complete.obs" then the correlation or covariance between each pair of variables is computed using all complete pairs of observations on those variables. This can result in covariance or correlation matrices which are not positive semi-definite, as well as NA entries if there are no complete pairs for that pair of variables.
