It is a trial and I am not related to redgate at all I just use there software.
A better alternative to Control Panel is to use this freeware program from SourceForge called Pathenator.
However, it only works for a system that has .NET 4.0 or greater such as Windows 7, Windows 8, or Windows 10.
The real trick is: Use a Backslash at the end of the target path where to copy the file. The /Y is for overwriting existing files, if you want no warnings.
Example:
xcopy /Y "C:\file\from\here.txt" "C:\file\to\here\"
If someone reads the original question to mean that they want to dynamically change the hover css and not just change the base css rule for the element, I've found this to work:
I have a dynamically loaded page that requires me to find out how high the container becomes after data is loaded. Once loaded, I want to change the hover effect of the css so that an element covers the resulting container. I need to change the css .daymark:hover rule to have a new height. This is how...
function changeAttr(attrName,changeThis,toThis){
var mysheet=document.styleSheets[1], targetrule;
var myrules=mysheet.cssRules? mysheet.cssRules: mysheet.rules;
for (i=0; i<myrules.length; i++){
if(myrules[i].selectorText.toLowerCase()==".daymark:hover"){ //find "a:hover" rule
targetrule=myrules[i];
break;
}
}
switch(changeThis)
{
case "height":
targetrule.style.height=toThis+"px";
break;
case "width":
targetrule.style.width=toThis+"px";
break;
}
}
@Transactional =javax.transaction.Transactional
. Put it just beside @Repository
.
The accepted answer to this question is awesome and should remain the accepted answer. However I ran into an issue with the code where the read stream was not always being ended/closed. Part of the solution was to send autoClose: true
along with start:start, end:end
in the second createReadStream
arg.
The other part of the solution was to limit the max chunksize
being sent in the response. The other answer set end
like so:
var end = positions[1] ? parseInt(positions[1], 10) : total - 1;
...which has the effect of sending the rest of the file from the requested start position through its last byte, no matter how many bytes that may be. However the client browser has the option to only read a portion of that stream, and will, if it doesn't need all of the bytes yet. This will cause the stream read to get blocked until the browser decides it's time to get more data (for example a user action like seek/scrub, or just by playing the stream).
I needed this stream to be closed because I was displaying the <video>
element on a page that allowed the user to delete the video file. However the file was not being removed from the filesystem until the client (or server) closed the connection, because that is the only way the stream was getting ended/closed.
My solution was just to set a maxChunk
configuration variable, set it to 1MB, and never pipe a read a stream of more than 1MB at a time to the response.
// same code as accepted answer
var end = positions[1] ? parseInt(positions[1], 10) : total - 1;
var chunksize = (end - start) + 1;
// poor hack to send smaller chunks to the browser
var maxChunk = 1024 * 1024; // 1MB at a time
if (chunksize > maxChunk) {
end = start + maxChunk - 1;
chunksize = (end - start) + 1;
}
This has the effect of making sure that the read stream is ended/closed after each request, and not kept alive by the browser.
I also wrote a separate StackOverflow question and answer covering this issue.
A void* can point to anything (it's a raw pointer without any type info).
I had this problem because I was not using StoryBorad, and on the project properties -> Deploy info -> Main interface was the name of the Main Xib.
I deleted the value in Main Interface and solved the problem.
If you want to exit your application from direct Second Activity without going to First Activity then try this code..`
In Second Activity put this code..
@Override
public void onBackPressed() {
new AlertDialog.Builder(this)
.setTitle("Really Exit?")
.setMessage("Are you sure you want to exit?")
.setNegativeButton(android.R.string.no, null)
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0, int arg1) {
setResult(RESULT_OK, new Intent().putExtra("EXIT", true));
finish();
}
}).create().show();
}
And Your First Activity Put this code.....
public class FirstActivity extends AppCompatActivity {
Button next;
private final static int EXIT_CODE = 100;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
next = (Button) findViewById(R.id.next);
next.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivityForResult(new Intent(FirstActivity.this, SecondActivity.class), EXIT_CODE);
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == EXIT_CODE) {
if (resultCode == RESULT_OK) {
if (data.getBooleanExtra("EXIT", true)) {
finish();
}
}
}
}
}
For Some People, Showing status bar by clearing FLAG_FULLSCREEN may not work,
Here is the solution that worked for me, (Documentation) (Flag Reference)
Hide Status Bar
// Hide Status Bar
if (Build.VERSION.SDK_INT < 16) {
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
View decorView = getWindow().getDecorView();
// Hide Status Bar.
int uiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
decorView.setSystemUiVisibility(uiOptions);
}
Show Status Bar
if (Build.VERSION.SDK_INT < 16) {
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
}
else {
View decorView = getWindow().getDecorView();
// Show Status Bar.
int uiOptions = View.SYSTEM_UI_FLAG_VISIBLE;
decorView.setSystemUiVisibility(uiOptions);
}
EF Core supports the views, here is the details.
This feature was added in EF Core 2.1 under the name of query types. In EF Core 3.0 the concept was renamed to keyless entity types. The [Keyless] Data Annotation became available in EFCore 5.0.
It is working not that much different than normal entities; but has some special points. According documentation:
- Cannot have a key defined.
- Are never tracked for changes in the DbContext and therefore are never inserted, updated or deleted on the database.
- Are never discovered by convention.
- Only support a subset of navigation mapping capabilities, specifically:
- They may never act as the principal end of a relationship.
- They may not have navigations to owned entities
- They can only contain reference navigation properties pointing to regular entities.
- Entities cannot contain navigation properties to keyless entity types.
- Need to be configured with a [Keyless] data annotation or a .HasNoKey() method call.
- May be mapped to a defining query. A defining query is a query declared in the model that acts as a data source for a keyless entity type
It is working like below:
public class Blog
{
public int BlogId { get; set; }
public string Name { get; set; }
public string Url { get; set; }
public ICollection<Post> Posts { get; set; }
}
public class Post
{
public int PostId { get; set; }
public string Title { get; set; }
public string Content { get; set; }
public int BlogId { get; set; }
}
If you don't have an existing View at database you should create like below:
db.Database.ExecuteSqlRaw(
@"CREATE VIEW View_BlogPostCounts AS
SELECT b.Name, Count(p.PostId) as PostCount
FROM Blogs b
JOIN Posts p on p.BlogId = b.BlogId
GROUP BY b.Name");
And than you should have a class to hold the result from the database view:
public class BlogPostsCount
{
public string BlogName { get; set; }
public int PostCount { get; set; }
}
And than configure the keyless entity type in OnModelCreating using the HasNoKey:
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder
.Entity<BlogPostsCount>(eb =>
{
eb.HasNoKey();
eb.ToView("View_BlogPostCounts");
eb.Property(v => v.BlogName).HasColumnName("Name");
});
}
And just configure the DbContext to include the DbSet:
public DbSet<BlogPostsCount> BlogPostCounts { get; set; }
you could inherit your controller then use it inside your action filter
inside your ActionFilterAttribute class:
if( filterContext.Controller is MyController )
if(filterContext.HttpContext.Session["login"] == null)
(filterContext.Controller as MyController).RedirectToAction("Login");
inside your base controller:
public class MyController : Controller
{
public void RedirectToAction(string actionName) {
base.RedirectToAction(actionName);
}
}
Cons. of this is to change all controllers to inherit from "MyController" class
For anyone who might still need this in the future. My answer is very similar to qaweb, just a lot less intimidating. There seems to be no cool automatic simple function to formate date in VBS. So you'll have to do it manually. I took the different components of the date and concatenated them together.
Dim timeStamp
timeStamp = Month(Date)&"-"&Day(Date)&"-"&Year(Date)
run = msgbox(timeStamp)
Which will result in 11-22-2019
(depending on the current date)
I like auxiliary functions to hide the crude details of bash. In this case, doing so adds even more (hidden) crudeness:
# The first ! negates the result (can't use -n to achieve this)
# the second ! expands the content of varname (can't do ${$varname})
function IsDeclared_Tricky
{
local varname="$1"
! [ -z ${!varname+x} ]
}
Because I first had bugs in this implementation (inspired by the answers of Jens and Lionel), I came up with a different solution:
# Ask for the properties of the variable - fails if not declared
function IsDeclared()
{
declare -p $1 &>/dev/null
}
I find it to be more straight-forward, more bashy and easier to understand/remember. Test case shows it is equivalent:
function main()
{
declare -i xyz
local foo
local bar=
local baz=''
IsDeclared_Tricky xyz; echo "IsDeclared_Tricky xyz: $?"
IsDeclared_Tricky foo; echo "IsDeclared_Tricky foo: $?"
IsDeclared_Tricky bar; echo "IsDeclared_Tricky bar: $?"
IsDeclared_Tricky baz; echo "IsDeclared_Tricky baz: $?"
IsDeclared xyz; echo "IsDeclared xyz: $?"
IsDeclared foo; echo "IsDeclared foo: $?"
IsDeclared bar; echo "IsDeclared bar: $?"
IsDeclared baz; echo "IsDeclared baz: $?"
}
main
The test case also shows that local var
does NOT declare var (unless followed by '='). For quite some time I thought i declared variables this way, just to discover now that i merely expressed my intention... It's a no-op, i guess.
IsDeclared_Tricky xyz: 1
IsDeclared_Tricky foo: 1
IsDeclared_Tricky bar: 0
IsDeclared_Tricky baz: 0
IsDeclared xyz: 1
IsDeclared foo: 1
IsDeclared bar: 0
IsDeclared baz: 0
BONUS: usecase
I mostly use this test to give (and return) parameters to functions in a somewhat "elegant" and safe way (almost resembling an interface...):
#auxiliary functions
function die()
{
echo "Error: $1"; exit 1
}
function assertVariableDeclared()
{
IsDeclared "$1" || die "variable not declared: $1"
}
function expectVariables()
{
while (( $# > 0 )); do
assertVariableDeclared $1; shift
done
}
# actual example
function exampleFunction()
{
expectVariables inputStr outputStr
outputStr="$inputStr world!"
}
function bonus()
{
local inputStr='Hello'
local outputStr= # remove this to trigger error
exampleFunction
echo $outputStr
}
bonus
If called with all requires variables declared:
Hello world!
else:
Error: variable not declared: outputStr
EntityManagerFactory is the standard implementation, it is the same across all the implementations. If you migrate your ORM for any other provider like EclipseLink, there will not be any change in the approach for handling the transaction. In contrast, if you use hibernate’s session factory, it is tied to hibernate APIs and cannot migrate to new vendor.
First you should use print_r($_FILES)
to debug, and see what it contains. :
your uploads.php
would look like:
//This is the directory where images will be saved
$target = "pics/";
$target = $target . basename( $_FILES['Filename']['name']);
//This gets all the other information from the form
$Filename=basename( $_FILES['Filename']['name']);
$Description=$_POST['Description'];
//Writes the Filename to the server
if(move_uploaded_file($_FILES['Filename']['tmp_name'], $target)) {
//Tells you if its all ok
echo "The file ". basename( $_FILES['Filename']['name']). " has been uploaded, and your information has been added to the directory";
// Connects to your Database
mysql_connect("localhost", "root", "") or die(mysql_error()) ;
mysql_select_db("altabotanikk") or die(mysql_error()) ;
//Writes the information to the database
mysql_query("INSERT INTO picture (Filename,Description)
VALUES ('$Filename', '$Description')") ;
} else {
//Gives and error if its not
echo "Sorry, there was a problem uploading your file.";
}
?>
EDIT: Since this is old post, currently it is strongly recommended to use either mysqli or pdo instead mysql_ functions in php
This could be even better to use
void replace(string& input, const string& from, const string& to)
{
while(true)
{
size_t startPosition = input.find(from);
if(startPosition == string::npos)
break;
input.replace(startPosition, from.length(), to);
}
}
This is what my final options section looks like for chart.js version 2.8.0.
options: {
legend: {
display: false //Have this or else legend will display as undefined
},
scales: {
//This will show money for y-axis labels with format of $xx.xx
yAxes: [{
ticks: {
beginAtZero: true,
callback: function(value) {
return (new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',
})).format(value);
}
}
}]
},
//This will show money in tooltip with format of $xx.xx
tooltips: {
callbacks: {
label: function (tooltipItem) {
return (new Intl.NumberFormat('en-US', {
style: 'currency',
currency: 'USD',
})).format(tooltipItem.value);
}
}
}
}
I wanted to show money values for both the y-axis and the tooltip values that show up when you hover over them. This works to show $49.99 and values with zero cents (ex: $50.00)
Primes are unique numbers. They are unique in that, the product of a prime with any other number has the best chance of being unique (not as unique as the prime itself of-course) due to the fact that a prime is used to compose it. This property is used in hashing functions.
Given a string “Samuel”, you can generate a unique hash by multiply each of the constituent digits or letters with a prime number and adding them up. This is why primes are used.
However using primes is an old technique. The key here to understand that as long as you can generate a sufficiently unique key you can move to other hashing techniques too. Go here for more on this topic about http://www.azillionmonkeys.com/qed/hash.html
http://computinglife.wordpress.com/2008/11/20/why-do-hash-functions-use-prime-numbers/
Make sure that the value of the column is really NULL and not an empty string or 0.
The easyest way is to change .attr() function to a javascript function .setAttribute()
$('#stop').click(function() {
$('next')[0].setAttribute('onclick','stopMoving()');
}
Use Heredocs to output muli-line strings containing variables. The syntax is...
$string = <<<HEREDOC
string stuff here
HEREDOC;
The "HEREDOC" part is like the quotes, and can be anything you want. The end tag must be the only thing on it's line i.e. no whitespace before or after, and must end in a colon. For more info check out the manual.

On SourceTree for Mac, right click the files you want to discard (in the Files in the working tree list), and choose Reset.
On SourceTree for Windows, right click the files you want to discard (in the Working Copy Changes list), and choose Discard.
On git, you'd simply do:
git reset --hard
to discard changes made to versioned files;
git clean -xdf
to erase new (untracked) files, including ignored ones (the x
option). d
is to also remove untracked directories and f
to force.
I was able to update it with markForCheck()
Import ChangeDetectorRef
import { ChangeDetectorRef } from '@angular/core';
Inject and instantiate it
constructor(private ref: ChangeDetectorRef) {
}
Finally mark change detection to take place
this.ref.markForCheck();
Here's an example where markForCheck() works and detectChanges() don't.

EDIT: This example doesn't portray the problem anymore :( I believe it might be running a newer Angular version where it's fixed.

Found a site on google explaining some changes, according to the author of the page fb does not allow custom buttons. Heres the website.
Unfortunately, it’s against Facebook’s developer policies, which state:
You must not circumvent our intended limitations on core Facebook features.
The Facebook Connect button is intended to be rendered in FBML, which means it’s only meant to look the way Facebook lets it.
Another possibility is to set the app:actionViewClass
attribute in your menu:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/get_item"
android:orderInCategory="1"
android:text="Get"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.AppCompatButton"/>
</menu>
In your code you can access this button after the menu was inflated:
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.sample, menu);
MenuItem getItem = menu.findItem(R.id.get_item);
if (getItem != null) {
AppCompatButton button = (AppCompatButton) getItem.getActionView();
//Set a ClickListener, the text,
//the background color or something like that
}
return super.onCreateOptionsMenu(menu);
}
This should be faster:
DELETE * FROM table_name;
because RDBMS don't have to look where
is what.
You should be fine with truncate
though:
truncate table table_name
Do you mean something like:
SELECT COLUMN1, COLUMN2 FROM MY_TABLE WHERE COLUMN1 = 'Value' OR COLUMN1 IS NULL
?
None of the answers above works for me. The only (let's say) solution has been to change the first TextView in a disabled EditText that receives focus and then add
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
in the onCreate callback to prevent keyboard to be shown. Now my first EditText looks like a TextView but can get the initial focus, finally.

<Button fx:id="closeButton" onAction="#closeButtonAction">
In your controller class:
@FXML private javafx.scene.control.Button closeButton;
@FXML
private void closeButtonAction(){
// get a handle to the stage
Stage stage = (Stage) closeButton.getScene().getWindow();
// do what you have to do
stage.close();
}
It might be the easiest way to input a string and find its length.
// Finding length of a string in C++
#include<iostream>
#include<string>
using namespace std;
int count(string);
int main()
{
string str;
cout << "Enter a string: ";
getline(cin,str);
cout << "\nString: " << str << endl;
cout << count(str) << endl;
return 0;
}
int count(string s){
if(s == "")
return 0;
if(s.length() == 1)
return 1;
else
return (s.length());

Put whatever you want to send to PHP in the value
attribute.
<select id="cmbMake" name="Make" >
<option value="">Select Manufacturer</option>
<option value="--Any--">--Any--</option>
<option value="Toyota">Toyota</option>
<option value="Nissan">Nissan</option>
</select>
You can also omit the value
attribute. It defaults to using the text.
If you don't want to change the HTML, you can put an array in your PHP to translate the values:
$makes = array(2 => 'Toyota',
3 => 'Nissan');
$maker = $makes[$_POST['Make']];

Do not do this object.hasOwnProperty(key))
. It's really bad because these methods may be shadowed by properties on the object in question - consider { hasOwnProperty: false }
- or, the object may be a null object (Object.create(null))
.
The best way is to do Object.prototype.hasOwnProperty.call(object, key)
or:
const has = Object.prototype.hasOwnProperty; // Cache the lookup once, in module scope.
/* Or */
import has from 'has'; // https://www.npmjs.com/package/has
// ...
console.log(has.call(object, key));
If the request could not be correctly parsed (including the request entity/body) the appropriate response is 400 Bad Request [1].
RFC 4918 states that 422 Unprocessable Entity is applicable when the request entity is syntactically well-formed, but semantically erroneous. So if the request entity is garbled (like a bad email format) use 400; but if it just doesn't make sense (like @example.com
) use 422.
If the issue is that, as stated in the question, user name/email already exists, you could use 409 Conflict [2] with a description of the conflict, and a hint about how to fix it (in this case, "pick a different user name/email"). However in the spec as written, 403 Forbidden [3] can also be used in this case, arguments about HTTP Authorization notwithstanding.
412 Precondition Failed [4] is used when a precondition request header (e.g. If-Match
) that was supplied by the client evaluates to false. That is, the client requested something and supplied preconditions, knowing full well that those preconditions might fail. 412 should never be sprung on the client out of the blue, and shouldn't be related to the request entity per se.
To elaborate slightly on @erikkallen's excellent answer, here is a function that allows all keyboard-based input types, including those introduced in HTML5:
$(document).unbind('keydown').bind('keydown', function (event) {
var doPrevent = false;
var INPUTTYPES = [
"text", "password", "file", "date", "datetime", "datetime-local",
"month", "week", "time", "email", "number", "range", "search", "tel",
"url"];
var TEXTRE = new RegExp("^" + INPUTTYPES.join("|") + "$", "i");
if (event.keyCode === 8) {
var d = event.srcElement || event.target;
if ((d.tagName.toUpperCase() === 'INPUT' && d.type.match(TEXTRE)) ||
d.tagName.toUpperCase() === 'TEXTAREA') {
doPrevent = d.readOnly || d.disabled;
} else {
doPrevent = true;
}
}
if (doPrevent) {
event.preventDefault();
}
});
A trick I haven't seen on here yet that doesn't use extglob
, find
, or grep
is to treat two file lists as sets and "diff" them using comm
:
comm -23 <(ls) <(ls *Music*)
comm
is preferable over diff
because it doesn't have extra cruft.
This returns all elements of set 1, ls
, that are not also in set 2, ls *Music*
. This requires both sets to be in sorted order to work properly. No problem for ls
and glob expansion, but if you're using something like find
, be sure to invoke sort
.
comm -23 <(find . | sort) <(find . | grep -i '.jpg' | sort)
Potentially useful.
For me following easy steps works:
1. git checkout myFeature
2. git rebase master
3. git push --force-with-lease
4. git branch -f master HEAD
5. git checkout master
6. git pull
After doing all above, we can delete myFeature branch as well by following command:
git push origin --delete myFeature
As nobody has mentioned reflector yet...
If you compile the following C# code:
static void Main(string[] args)
{
var x = "hello";
string y = "hello again!";
Console.WriteLine(x);
Console.WriteLine(y);
}
Then use reflector on it, you get:
// Methods
private static void Main(string[] args)
{
string x = "hello";
string y = "hello again!";
Console.WriteLine(x);
Console.WriteLine(y);
}
So the answer is clearly no runtime performance hit!
This is the most elegant solution I've been using for a while. It doesn't require external counter variable and it provides nice degree of encapsulation.
var urls = ['http://..', 'http://..', ..];
function ajaxRequest (urls) {
if (urls.length > 0) {
$.ajax({
method: 'GET',
url: urls.pop()
})
.done(function (result)) {
ajaxRequest(urls);
});
}
}
ajaxRequest(urls);
Why not try MySQL GUI Tools? It's light, and does its job well.
The git blame
command annotates lines with information from the revision which last modified the line, and... with Git 2.22 (Q2 2019), will do so faster, because of a performance fix around "git blame
", especially in a linear history (which is the norm we should optimize for).
See commit f892014 (02 Apr 2019) by David Kastrup (fedelibre
).
(Merged by Junio C Hamano -- gitster
-- in commit 4d8c4da, 25 Apr 2019)
blame.c
: don't drop origin blobs as eagerlyWhen a parent blob already has chunks queued up for blaming, dropping the blob at the end of one blame step will cause it to get reloaded right away, doubling the amount of I/O and unpacking when processing a linear history.
Keeping such parent blobs in memory seems like a reasonable optimization that should incur additional memory pressure mostly when processing the merges from old branches.

Update: This answer has led to the development of ng2-completer
an Angular2 autocomplete component.
This is the list of existing autocomplete components for Angular2:
Credit goes to @dan-cancro for coming up with the idea
Keeping the original answer for those who wish to create their own directive:
To display autocomplete list we first need an attribute directive that will return the list of suggestions based on the input text and then display them in a dropdown. The directive has 2 options to display the list:
It looks to me that 2nd way is a better choice as it uses angular 2 core mechanisms instead of bypassing them by working directly with the DOM and therefore I'll use this method.
This is the directive code:
"use strict";
import {Directive, DynamicComponentLoader, Input, ComponentRef, Output, EventEmitter, OnInit, ViewContainerRef} from "@angular/core";
import {Promise} from "es6-promise";
import {AutocompleteList} from "./autocomplete-list";
@Directive({
selector: "[ng2-autocomplete]", // The attribute for the template that uses this directive
host: {
"(keyup)": "onKey($event)" // Liten to keyup events on the host component
}
})
export class AutocompleteDirective implements OnInit {
// The search function should be passed as an input
@Input("ng2-autocomplete") public search: (term: string) => Promise<Array<{ text: string, data: any }>>;
// The directive emits ng2AutocompleteOnSelect event when an item from the list is selected
@Output("ng2AutocompleteOnSelect") public selected = new EventEmitter();
private term = "";
private listCmp: ComponentRef<AutocompleteList> = undefined;
private refreshTimer: any = undefined;

The directive dynamically loads a dropdown component, this is a sample of such a component using bootstrap 4:
"use strict";
import {Component, Output, EventEmitter} from "@angular/core";
@Component({
selector: "autocomplete-list",
template: `<div class="dropdown-menu search-results">
<a *ngFor="let item of list" class="dropdown-item" (click)="onClick(item)">{{item.text}}</a>
</div>`, // Use a bootstrap 4 dropdown-menu to display the list
styles: [".search-results { position: relative; right: 0; display: block; padding: 0; overflow: hidden; font-size: .9rem;}"]
})
export class AutocompleteList {
// Emit a selected event when an item in the list is selected
@Output() public selected = new EventEmitter();
public list;
/**
* Listen for a click event on the list
*/
public onClick(item: {text: string, data: any}) {
this.selected.emit(item);
}
}
To use the directive in another component you need to import the directive, include it in the components directives and provide it with a search function and event handler for the selection:
"use strict";
import {Component} from "@angular/core";
import {AutocompleteDirective} from "../component/ng2-autocomplete/autocomplete";
@Component({
selector: "my-cmp",
directives: [AutocompleteDirective],
template: `<input class="form-control" type="text" [ng2-autocomplete]="search()" (ng2AutocompleteOnSelect)="onItemSelected($event)" autocomplete="off">`
})
export class MyComponent {
/**
* generate a search function that returns a Promise that resolves to array of text and optionally additional data
*/
public search() {
return (filter: string): Promise<Array<{ text: string, data: any }>> => {
// do the search
resolve({text: "one item", data: null});
};
}
/**
* handle item selection
*/
public onItemSelected(selected: { text: string, data: any }) {
console.log("selected: ", selected.text);
}
}
Update: code compatible with angular2 rc.1
os.system('cls')
works fine when I open them. It opens in cmd style.
The basic premise of the question and the answers are wrong. Every Select in a union can have a where clause. It's the ORDER BY in the first query that's giving yo the error.
I had an onpremises HA installation, a master and a worker stopped working returning a NOTReady status. Checking the kubelet logs on the nodes I found out this problem:
failed to run Kubelet: Running with swap on is not supported, please disable swap! or set --fail-swap-on flag to false
Disabling swap on nodes with
swapoff -a
and restarting the kubelet
systemctl restart kubelet
did the work.
When you don't have a PC on hand, you could use Eruda, which is devtools for mobile browsers https://github.com/liriliri/eruda
It is provided as embeddable javascript and also a bookmarklet (pasting bookmarklet in chrome removes the javascript: prefix, so you have to type it yourself)
Yes, case insensitivity can be enabled and disabled at will in Java regex.
It looks like you want something like this:
System.out.println(
"Have a meRry MErrY Christmas ho Ho hO"
.replaceAll("(?i)\\b(\\w+)(\\s+\\1)+\\b", "$1")
);
// Have a meRry Christmas ho
Note that the embedded Pattern.CASE_INSENSITIVE
flag is (?i)
not \?i
. Note also that one superfluous \b
has been removed from the pattern.
The (?i)
is placed at the beginning of the pattern to enable case-insensitivity. In this particular case, it is not overridden later in the pattern, so in effect the whole pattern is case-insensitive.
It is worth noting that in fact you can limit case-insensitivity to only parts of the whole pattern. Thus, the question of where to put it really depends on the specification (although for this particular problem it doesn't matter since \w
is case-insensitive.
To demonstrate, here's a similar example of collapsing runs of letters like "AaAaaA"
to just "A"
.
System.out.println(
"AaAaaA eeEeeE IiiIi OoooOo uuUuUuu"
.replaceAll("(?i)\\b([A-Z])\\1+\\b", "$1")
); // A e I O u
Now suppose that we specify that the run should only be collapsed only if it starts with an uppercase letter. Then we must put the (?i)
in the appropriate place:
System.out.println(
"AaAaaA eeEeeE IiiIi OoooOo uuUuUuu"
.replaceAll("\\b([A-Z])(?i)\\1+\\b", "$1")
); // A eeEeeE I O uuUuUuu
More generally, you can enable and disable any flag within the pattern as you wish.
java.util.regex.Pattern
/regex/i
(Pattern.CASE_INSENSITIVE
in Java), you can do /(?i)regex/
/first(?i)second(?-i)third/
/first(?i:second)third/
\b
between a \w
and a \s
)int *a[]
, when used as a function parameter (but not in normal declarations), is a pointer to a pointer, not a pointer to an array (in normal declarations, it is an array of pointers). A pointer to an array looks like this:
int (*aptr)[N]
Where N
is a particular positive integer (not a variable).
If you make your function a template, you can do it and you don't even need to pass the size of the array (because it is automatically deduced):
template<size_t SZ>
void generateArray(int (*aptr)[SZ])
{
for (size_t i=0; i<SZ; ++i)
(*aptr)[i] = rand() % 9;
}
int main()
{
int a[5];
generateArray(&a);
}
You could also take a reference:
template<size_t SZ>
void generateArray(int (&arr)[SZ])
{
for (size_t i=0; i<SZ; ++i)
arr[i] = rand() % 9;
}
int main()
{
int a[5];
generateArray(a);
}
This solution works for Integer length size =1.
Integer input = 9;
Character.valueOf((char) input.toString().charAt(0))
if size >1 we need to use for loop and iterate through.
You should seriously consider dhiller's answer:
new ArrayList(set)
(or a new LinkedList(set)
, whatever).I think that the solution you posted with the NoDuplicatesList
has some issues, mostly with the contains()
method, plus your class does not handle checking for duplicates in the Collection passed to your addAll()
method.
If you use jdk8 see @Nathaniel Johnson's answer as that is better.
I think that many of the answer here are complex or not easily read. With branch prediction so efficient why you simply not use a if statement?
public static String join(List<String> fooList){
if (fooList.isEmpty()) return "";
StringBuilder sb = null;
for (String element : fooList) {
if (sb == null) {
sb = new StringBuilder();
} else {
sb.append(", ");
}
sb.append(element);
}
return sb.toString();
}
Something that should be mentioned is that Apache uses a simple for loop with an if statement inside it like this (it uses an array as its index to know the first element), and openjdk 8 does the same but in separated methods calls instead of a simple loop.
If you want to iterate over both the keys and the values in a key sorted order, this form is quite succinct
let d = [
"A" : [1, 2],
"Z" : [3, 4],
"D" : [5, 6]
]
Swift 1,2:
for (k,v) in Array(d).sorted({$0.0 < $1.0}) {
println("\(k):\(v)")
}
Swift 3+:
for (k,v) in Array(d).sorted(by: {$0.0 < $1.0}) {
println("\(k):\(v)")
}
I had the same issue.
Solution was to change the platform of my current solution to x64.

This is not right. Here's how you should use Runtime.exec()
. You might also try its more modern cousin, ProcessBuilder
:
All of the above show hard it can be to make a nice, flexible (or forbid an overloaded) function in LaTeX!!! (that TeX code looks like greek to me)
well, just to add my recent (albeit not as flexible) development, here's what I've recently used in my thesis doc, with
\usepackage{ifthen} % provides conditonals...
Start the command, with the "optional" command set blank by default:
\newcommand {\figHoriz} [4] [] {
I then have the macro set a temporary variable, \temp{}, differently depending on whether or not the optional argument is blank. This could be extended to any passed argument.
\ifthenelse { \equal {#1} {} } %if short caption not specified, use long caption (no slant)
{ \def\temp {\caption[#4]{\textsl{#4}}} } % if #1 == blank
{ \def\temp {\caption[#1]{\textsl{#4}}} } % else (not blank)
Then I run the macro using the \temp{} variable for the two cases. (Here it just sets the short-caption to equal the long caption if it wasn't specified by the user).
\begin{figure}[!]
\begin{center}
\includegraphics[width=350 pt]{#3}
\temp %see above for caption etc.
\label{#2}
\end{center}
\end{figure}
}
In this case I only check for the single, "optional" argument that \newcommand{} provides. If you were to set it up for, say, 3 "optional" args, you'd still have to send the 3 blank args... eg.
\MyCommand {first arg} {} {} {}
which is pretty silly, I know, but that's about as far as I'm going to go with LaTeX - it's just not that sensical once I start looking at TeX code... I do like Mr. Robertson's xparse method though, perhaps I'll try it...
To merge a local directory into a directory within an image, do this. It will not delete files already present within the image. It will only add files that are present locally, overwriting the files in the image if a file of the same name already exists.

Keep in mind that @"%d" will only work on 32 bit. Once you start using NSInteger for compatibility if you ever compile for a 64 bit platform, you should use @"%ld" as your format specifier.

this is actually the summation of an arithmatic progression with common difference as 1. So this is a special case of sum of natural numbers. Its easy can be done with a single line of code.
int i = 100;
// Implement the fomrulae n*(n+1)/2
int sum = (i*(i+1))/2;
System.out.println(sum);

I also want to know is it possible to push the compiled binary into android device or AVD and run using the terminal of the android device or AVD?
here you can see NestedVM
NestedVM provides binary translation for Java Bytecode. This is done by having GCC compile to a MIPS binary which is then translated to a Java class file. Hence any application written in C, C++, Fortran, or any other language supported by GCC can be run in 100% pure Java with no source changes.
Example: Cross compile Hello world C program and run it on android

Unfortunately, Dictionary has problems with Model Binding in MVC. Read the full story here. Instead, create a custom model binder to get the Dictionary as a parameter for the controller action.
To solve your requirement, here is the working solution -
First create your ViewModels in following way. PersonModel can have list of RoleModels.
public class PersonModel
{
public List<RoleModel> Roles { get; set; }
public string Name { get; set; }
}
public class RoleModel
{
public string RoleName { get; set;}
public string Description { get; set;}
}
Then have a index action which will be serving basic index view -
public ActionResult Index()
{
return View();
}
Index view will be having following JQuery AJAX POST operation -
<script src="~/Scripts/jquery-1.10.2.min.js"></script>
<script>
$(function () {
$('#click1').click(function (e) {
var jsonObject = {
"Name" : "Rami",
"Roles": [{ "RoleName": "Admin", "Description" : "Admin Role"}, { "RoleName": "User", "Description" : "User Role"}]
};
$.ajax({
url: "@Url.Action("AddUser")",
type: "POST",
data: JSON.stringify(jsonObject),
contentType: "application/json; charset=utf-8",
dataType: "json",
error: function (response) {
alert(response.responseText);
},
success: function (response) {
alert(response);
}
});
});
});
</script>
<input type="button" value="click1" id="click1" />
Index action posts to AddUser action -
[HttpPost]
public ActionResult AddUser(PersonModel model)
{
if (model != null)
{
return Json("Success");
}
else
{
return Json("An Error Has occoured");
}
}
So now when the post happens you can get all the posted data in the model parameter of action.
Update:
For asp.net core, to get JSON data as your action parameter you should add the [FromBody]
attribute before your param name in your controller action. Note: if you're using ASP.NET Core 2.1, you can also use the [ApiController]
attribute to automatically infer the [FromBody] binding source for your complex action method parameters. (Doc)
You could fill the dependend cell (D2) by a User Defined Function (VBA Macro Function) that takes the value of the C2-Cell as input parameter, returning the current date as ouput.
Having C2 as input parameter for the UDF in D2 tells Excel that it needs to reevaluate D2 everytime C2 changes (that is if auto-calculation of formulas is turned on for the workbook).
EDIT:
Here is some code:
For the UDF:
Public Function UDF_Date(ByVal data) As Date
UDF_Date = Now()
End Function
As Formula in D2:
=UDF_Date(C2)
You will have to give the D2-Cell a Date-Time Format, or it will show a numeric representation of the date-value.
And you can expand the formula over the desired range by draging it if you keep the C2 reference in the D2-formula relative.
Note: This still might not be the ideal solution because every time Excel recalculates the workbook the date in D2 will be reset to the current value. To make D2 only reflect the last time C2 was changed there would have to be some kind of tracking of the past value(s) of C2. This could for example be implemented in the UDF by providing also the address alonside the value of the input parameter, storing the input parameters in a hidden sheet, and comparing them with the previous values everytime the UDF gets called.
Addendum:
Here is a sample implementation of an UDF that tracks the changes of the cell values and returns the date-time when the last changes was detected. When using it, please be aware that:
The usage of the UDF is the same as described above.
The UDF works only for single cell input ranges.
The cell values are tracked by storing the last value of cell and the date-time when the change was detected in the document properties of the workbook. If the formula is used over large datasets the size of the file might increase considerably as for every cell that is tracked by the formula the storage requirements increase (last value of cell + date of last change.) Also, maybe Excel is not capable of handling very large amounts of document properties and the code might brake at a certain point.
If the name of a worksheet is changed all the tracking information of the therein contained cells is lost.
The code might brake for cell-values for which conversion to string is non-deterministic.
The code below is not tested and should be regarded only as proof of concept. Use it at your own risk.
Public Function UDF_Date(ByVal inData As Range) As Date
Dim wb As Workbook
Dim dProps As DocumentProperties
Dim pValue As DocumentProperty
Dim pDate As DocumentProperty
Dim sName As String
Dim sNameDate As String
Dim bDate As Boolean
Dim bValue As Boolean
Dim bChanged As Boolean
bDate = True
bValue = True
bChanged = False
Dim sVal As String
Dim dDate As Date
sName = inData.Address & "_" & inData.Worksheet.Name
sNameDate = sName & "_dat"
sVal = CStr(inData.Value)
dDate = Now()
Set wb = inData.Worksheet.Parent
Set dProps = wb.CustomDocumentProperties
On Error Resume Next
Set pValue = dProps.Item(sName)
If Err.Number <> 0 Then
bValue = False
Err.Clear
End If
On Error GoTo 0
If Not bValue Then
bChanged = True
Set pValue = dProps.Add(sName, False, msoPropertyTypeString, sVal)
Else
bChanged = pValue.Value <> sVal
If bChanged Then
pValue.Value = sVal
End If
End If
On Error Resume Next
Set pDate = dProps.Item(sNameDate)
If Err.Number <> 0 Then
bDate = False
Err.Clear
End If
On Error GoTo 0
If Not bDate Then
Set pDate = dProps.Add(sNameDate, False, msoPropertyTypeDate, dDate)
End If
If bChanged Then
pDate.Value = dDate
Else
dDate = pDate.Value
End If
UDF_Date = dDate
End Function
Make the insertion of the date conditional upon the range.
This has an advantage of not changing the dates unless the content of the cell is changed, and it is in the range C2:C2, even if the sheet is closed and saved, it doesn't recalculate unless the adjacent cell changes.

If I understand you correctly, you need to use -SearchBase:
Get-ADUser -SearchBase "OU=Accounts,OU=RootOU,DC=ChildDomain,DC=RootDomain,DC=com" -Filter *
Note that Get-ADUser defaults to using
-SearchScope Subtree
so you don't need to specify it. It's this that gives you all sub-OUs (and sub-sub-OUs, etc.).
Somebody posted quite a few form fields to your page. The new default max introduced by the recent security update is 1000.
Try adding the following setting in your web.config's <appsettings>
block. in this block you are maximizing the MaxHttpCollection values this will override the defaults set by .net Framework. you can change the value accordingly as per your form needs
<appSettings>
<add key="aspnet:MaxHttpCollectionKeys" value="2001" />
</appSettings>
For more information please read this post. For more insight into the security patch by microsoft you can read this Knowledge base article
The length of a base64 encoded string is always a multiple of 4. If it is not a multiple of 4, then =
characters are appended until it is. A query string of the form ?name=value
has problems when the value
contains =
charaters (some of them will be dropped, I don't recall the exact behavior). You may be able to get away with appending the right number of =
characters before doing the base64 decode.
Edit 1
You may find that the value of UserNameToVerify
has had "+"
's changed to " "
's so you may need to do something like so:
a = a.Replace(" ", "+");
This should get the length right;
int mod4 = a.Length % 4;
if (mod4 > 0 )
{
a += new string('=', 4 - mod4);
}
Of course calling UrlEncode
(as in LukeH's answer) should make this all moot.
Do you mean something like this?

Python 3.0 doesn't have sys.maxint any more since Python 3's ints are of arbitrary length. Instead of sys.maxint it has sys.maxsize; the maximum size of a positive sized size_t aka Py_ssize_t.
Use this code.
driver.FindElement(By.XPath(".//[@id='header']/div/div[3]/div/form/input[1]")).SendKeys("25025");
you may also want to look at that already answered question Differences in string compare methods in C#

Have a nice day
I don't think that can be done RELIABLY with built in methods on the native Date object. The toLocaleString
method gets close, but if I am remembering correctly, it won't work correctly in IE < 10. If you are able to use a library for this task, MomentJS is a really amazing library; and it makes working with dates and times easy. Otherwise, I think you will have to write a basic function to give you the format that you are after.
function formatDate(date) {
var year = date.getFullYear(),
month = date.getMonth() + 1, // months are zero indexed
day = date.getDate(),
hour = date.getHours(),
minute = date.getMinutes(),
second = date.getSeconds(),
hourFormatted = hour % 12 || 12, // hour returned in 24 hour format
minuteFormatted = minute < 10 ? "0" + minute : minute,
morning = hour < 12 ? "am" : "pm";
return month + "/" + day + "/" + year + " " + hourFormatted + ":" +
minuteFormatted + morning;
}
Another way of doing this:
Dim strings() As String = {}
Testing that it is an empty string array:
MessageBox.Show("count: " + strings.Count.ToString)
Will show a message box saying "count: 0".

If you have settled on a particular set of tools to access / modify your databases, I would go with whatever extension they expect you to use. This will avoid needless friction when doing development tasks.
For instance, SQLiteStudio v3.1.1 defaults to looking for files with the following extensions:
(db|sdb|sqlite|db3|s3db|sqlite3|sl3|db2|s2db|sqlite2|sl2
)
If necessary for deployment your installation mechanism could rename the file if obscuring the file type seems useful to you (as some other answers have suggested). Filename requirements for development and deployment can be different.
You can always write it like this
String[] errorSoon = {"Hello","World"};
For (int x=0;x<errorSoon.length;x++) // in this way u create a for loop that would like display the elements which are inside the array errorSoon.oh errorSoon.length is the same as errorSoon<2
{
System.out.println(" "+errorSoon[x]); // this will output those two words, at the top hello and world at the bottom of hello.
}
You should think JS for behaviour, and CSS for visual candy as much as possible. By changing your HTML a bit :
<td class="post">
<a class="p-edit-btn" href="#" onclick="showStuff(this.parentNode);return false;">Edit</a>
<span id="answer1" class="post-answer">
<textarea rows="10" cols="115"></textarea>
</span>
<span class="post-text" id="text1">Lorem ipsum ... </span>
</td>
You'll be able to switch from one view to the other simply using CSS rules :
td.post-editing > a.post-edit-btn,
td.post-editing > span.post-text,
td.post > span.post-answer
{
display : none;
}
And JS code that switch between the two classes
<script type="text/javascript">
function showStuff(aPostTd) {
aPostTd.className="post-editing";
}
</script>
Make 'maven.test.skip' as false in pom file, while building project test reource will come under test-classes.
<maven.test.skip>false</maven.test.skip>
Faced with the same problem, I was able to solve it using only vanilla JS, but in an ugly way. To be more accurate, in a non-procedural way. I removed all my function parameters and return values and replaced them with global variables, and now the functions only serve as containers for lines of code - they're no longer logical units.
In my case, I also had the added complication of needing many confirmations (as a parser works through a text). My solution was to put everything up to the first confirmation in a JS function that ends by painting my custom popup on the screen, and then terminating.
Then the buttons in my popup call another function that uses the answer and then continues working (parsing) as usual up to the next confirmation, when it again paints the screen and then terminates. This second function is called as often as needed.
Both functions also recognize when the work is done - they do a little cleanup and then finish for good. The result is that I have complete control of the popups; the price I paid is in elegance.
Probably the easiest to hide a div and show a div in PHP based on a variables and the operator.
<?php
$query3 = mysql_query($query3);
$numrows = mysql_num_rows($query3);
?>
<html>
<?php if($numrows > null){ ?>
no meow :-(
<?php } ?>
<?php if($numrows < null){ ?>
lots of meow
<?php } ?>
</html>
Here is my original code before adding your requirements:
<?php
$address = 'meow';
?>
<?php if($address == null){ ?>
no meow :-(
<?php } ?>
<?php if($address != null){ ?>
lots of meow
<?php } ?>
In SQL Server Management Studio of Any Version, Use
BIT
as Data Type
which will provide you with True
or False
Value options. in case you want to use Only 1
or 0
then you can use this method:
CREATE TABLE SampleBit(
bar int NOT NULL CONSTRAINT CK_foo_bar CHECK (bar IN (-1, 0, 1))
)
But I will strictly advise BIT
as The BEST Option. Hope fully it's help someone.
While iterating over a JSON array (org.json.JSONArray, built into Android), watch out for null objects; for example, you may get "null"
instead of a null string.
A check may look like:
s[i] = array.isNull(i) ? null : array.getString(i);
The issue pointed in the comment is valid, so here is a different revision that's immune to that:
function show_alert() {
if(!confirm("Do you really want to do this?")) {
return false;
}
this.form.submit();
}
Have you tried using the JQuery
change event?
$("#g01-01").change(function() {
if(this.checked) {
//Do stuff
}
});
Then you can also remove onchange="doalert(this.id)"
from your checkbox :)
Edit:
I don't know if you are using JQuery
, but if you're not yet using it, you will need to put the following script in your page so you can use it:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
There are a few options:
Read all sheets directly into an ordered dictionary.
import pandas as pd
# for pandas version >= 0.21.0
sheet_to_df_map = pd.read_excel(file_name, sheet_name=None)
# for pandas version < 0.21.0
sheet_to_df_map = pd.read_excel(file_name, sheetname=None)
Read the first sheet directly into dataframe
df = pd.read_excel('excel_file_path.xls')
# this will read the first sheet into df
Read the excel file and get a list of sheets. Then chose and load the sheets.
xls = pd.ExcelFile('excel_file_path.xls')
# Now you can list all sheets in the file
xls.sheet_names
# ['house', 'house_extra', ...]
# to read just one sheet to dataframe:
df = pd.read_excel(file_name, sheetname="house")
Read all sheets and store it in a dictionary. Same as first but more explicit.
# to read all sheets to a map
sheet_to_df_map = {}
for sheet_name in xls.sheet_names:
sheet_to_df_map[sheet_name] = xls.parse(sheet_name)
# you can also use sheet_index [0,1,2..] instead of sheet name.
Thanks @ihightower for pointing it out way to read all sheets and @toto_tico for pointing out the version issue.
sheetname : string, int, mixed list of strings/ints, or None, default 0 Deprecated since version 0.21.0: Use sheet_name instead Source Link
Update - as of Spark 1.6, you can simply use the built-in csv data source:
spark: SparkSession = // create the Spark Session
val df = spark.read.csv("file.txt")
You can also use various options to control the CSV parsing, e.g.:
val df = spark.read.option("header", "false").csv("file.txt")
For Spark version < 1.6:
The easiest way is to use spark-csv - include it in your dependencies and follow the README, it allows setting a custom delimiter (;
), can read CSV headers (if you have them), and it can infer the schema types (with the cost of an extra scan of the data).
Alternatively, if you know the schema you can create a case-class that represents it and map your RDD elements into instances of this class before transforming into a DataFrame, e.g.:
case class Record(id: Int, name: String)
val myFile1 = myFile.map(x=>x.split(";")).map {
case Array(id, name) => Record(id.toInt, name)
}
myFile1.toDF() // DataFrame will have columns "id" and "name"
on Mac OS X (BSD find): Same as accepted answer, the .*/
prefix is needed to match a complete path:
$ find -E . -regex ".*/[a-f0-9\-]{36}.jpg"
man find
says -E
uses extended regex support
Use it as a top level function in some common class of your project such as Utils.kt
// Vibrates the device for 100 milliseconds.
fun vibrateDevice(context: Context) {
val vibrator = getSystemService(context, Vibrator::class.java)
vibrator?.let {
if (Build.VERSION.SDK_INT >= 26) {
it.vibrate(VibrationEffect.createOneShot(100, VibrationEffect.DEFAULT_AMPLITUDE))
} else {
@Suppress("DEPRECATION")
it.vibrate(100)
}
}
}
And then call it anywhere in your code as following:
vibrateDevice(requireContext())
Using Vibrator::class.java
is more type safe than using String
constants.
We check the vibrator
for nullability using let { }
, because if the vibration is not available for the device, the vibrator
will be null
.
It's ok to supress deprecation in else
clause, because the warning is from newer SDK.
We don't need to ask for permission at runtime for using vibration. But we need to declare it in AndroidManifest.xml
as following:
<uses-permission android:name="android.permission.VIBRATE"/>
I intend to add some extra explanation regarding the attempts of OP and other answers as well.
You can use John Kugelmans' solution like this too:
grep -x "ABB\.log" a.tmp
quoting the string and escaping the dot (.
) makes it to not need the -F
flag any more.
You need to escape the .
(dot) (because it matches any character (not only .
) if not escaped) or use the -F
flag with grep. -F
flag makes it a fixed string (not a regex).
If you don't quote the string, you may need double backslash to escape the dot (.
):
grep -x ABB\\.log a.tmp
$ echo "ABBElog"|grep -x ABB.log
ABBElog #matched !!!
$ echo "ABBElog"|grep -x "ABB\.log"
#returns empty string, no match
-x
forces to match the whole line..
without -F
flag are wrong.-x
switch by wrapping your pattern string with ^
and $
. In this case make sure you don't use -F
, instead escape the .
, because -F
will prevent the regex interpretation of ^
and $
.If you want to match a string starting with -
, then you should use --
with grep. Whatever follows --
will be taken as an input (not option).
Example:
echo -f |grep -- "-f" # where grep "-f" will show error
echo -f |grep -F -- "-f" # whre grep -F "-f" will show error
grep "pat" -- "-file" # grep "pat" "-file" won't work. -file is the filename
You should add next permission:
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
And then here is usages in code:
val externalFilesDir = context.getExternalFilesDir(DIRECTORY_DOWNLOADS)
1.include
<script type="text/javascript" src="http://www.youtube.com/player_api"></script>
2.add your youtube iframe.
<iframe id="player" src="http://www.youtube.com/embed/YOURID?rel=0&wmode=Opaque&enablejsapi=1" frameborder="0"></iframe>
3.magic time.
<script>
var player;
function onYouTubePlayerAPIReady() {player = new YT.Player('player');}
//so on jquery event or whatever call the play or stop on the video.
//to play player.playVideo();
//to stop player.stopVideo();
</script>
In SQL, this problem could be solved by several methods:
select * from df1 where exists (select * from df2 where df2.user_id = df1.user_id)
union all
select * from df2 where exists (select * from df1 where df1.user_id = df2.user_id)
or join and then unpivot (possible in SQL server)
select
df1.user_id,
c.rating
from df1
inner join df2 on df2.user_i = df1.user_id
outer apply (
select df1.rating union all
select df2.rating
) as c
Second one could be written in pandas with something like:
>>> df1 = pd.DataFrame({"user_id":[1,2,3], "rating":[10, 15, 20]})
>>> df2 = pd.DataFrame({"user_id":[3,4,5], "rating":[30, 35, 40]})
>>>
>>> df4 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df = pd.merge(df1, df2, on='user_id', suffixes=['_1', '_2'])
>>> df3 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df4 = df[['user_id', 'rating_2']].rename(columns={'rating_2':'rating'})
>>> pd.concat([df3, df4], axis=0)
user_id rating
0 3 20
0 3 30
You can't alloc UIImage, this is impossible. Proper code with UIImageView allocate:
UIImageView *_image = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"something.png"]] ;
Draw image:
CGContextDrawImage(context, rect, _image.image.CGImage);
public class RemoveDecimalPoint{
public static void main(String []args){
System.out.println(""+ removePoint(250022005.60));
}
public static String removePoint(double number) {
long x = (long) number;
return x+"";
}
}
Like bruno said, you're better configuring it yourself. Here's how I do it. Start by creating a properties file (/etc/myapp/config.properties).
javax.net.ssl.keyStore = /etc/myapp/keyStore
javax.net.ssl.keyStorePassword = 123456
Then load the properties to your environment from your code. This makes your application configurable.
FileInputStream propFile = new FileInputStream("/etc/myapp/config.properties");
Properties p = new Properties(System.getProperties());
p.load(propFile);
System.setProperties(p);
They change it again. At this moment documentation does not fit actual situation.
Commonly all works as expected with one small difference. Login from Devices
config now moves to Products -> Facebook Login
.
So you need to:
App id
from headline,Client Token
from app Settings -> Advanced
. There is also Native or desktop app?
question/config. I turn it on.Add product
and then Get started
on Facebook login
. Move back to your app config, click to newly added Facebook login
and you'll see your Login from Devices
config.You could use pandas plot as @Bharath suggest:
import seaborn as sns
sns.set()
df.set_index('App').T.plot(kind='bar', stacked=True)
Output:
Updated:
from matplotlib.colors import ListedColormap
df.set_index('App')\
.reindex_axis(df.set_index('App').sum().sort_values().index, axis=1)\
.T.plot(kind='bar', stacked=True,
colormap=ListedColormap(sns.color_palette("GnBu", 10)),
figsize=(12,6))
Updated Pandas 0.21.0+ reindex_axis
is deprecated, use reindex
from matplotlib.colors import ListedColormap
df.set_index('App')\
.reindex(df.set_index('App').sum().sort_values().index, axis=1)\
.T.plot(kind='bar', stacked=True,
colormap=ListedColormap(sns.color_palette("GnBu", 10)),
figsize=(12,6))
Output:
I think what you want is something like:
=INDEX(B:B,MATCH(C2,A:A,0))
I should mention that MATCH checks the position at which the value can be found within A:A (given the 0
, or FALSE, parameter, it looks only for an exact match and given its nature, only the first instance found) then INDEX returns the value at that position within B:B.
You can use urllib2
import urllib2
content = urllib2.urlopen(some_url).read()
print content
Also you can use httplib
import httplib
conn = httplib.HTTPConnection("www.python.org")
conn.request("HEAD","/index.html")
res = conn.getresponse()
print res.status, res.reason
# Result:
200 OK
or the requests library
import requests
r = requests.get('https://api.github.com/user', auth=('user', 'pass'))
r.status_code
# Result:
200
You can use system
:
system("/usr/local/bin/foo.sh");
This will block while executing it using sh -c
, then return the status code.
These 2 methods I tried are not working:
sudo npm cache clean -f
sudo npm install -g n
sudo n stable
After trying, node -v
still shows the old version of node.
Below method works for me:
Step 1: Install nvm (for more details: https://github.com/creationix/nvm#installation)
Open terminal and type this command:
curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash
Close terminal and reopen it.
Type this command to check if nvm is installed:
command -v nvm
Step 2: To download, compile, and install the latest release of node, type this:
nvm install node
("node" is an alias for the latest version)
To check if node gets the latest version (v10.11.0).
Installing the latest node also installs the latest npm.
Check if npm gets the latest version (6.4.1).
Nope, what you have is fine. You could also do this as a formula (sliderVal < 5 ? (1.0 - 0.1 * sliderVal) : 1.0
) or use a Map<Integer,Double>
, but what you have is fine.
The "coef" option of the geom_boxplot function allows to change the outlier cutoff in terms of interquartile ranges. This option is documented for the function stat_boxplot. To deactivate outliers (in other words they are treated as regular data), one can instead of using the default value of 1.5 specify a very high cutoff value:
library(ggplot2)
# generate data with outliers:
df = data.frame(x=1, y = c(-10, rnorm(100), 10))
# generate plot with increased cutoff for outliers:
ggplot(df, aes(x, y)) + geom_boxplot(coef=1e30)
Granted, there are definitely different thinking, in my world, I cannot enforce "Never pass a null" because I am dealing with uncontrollable third parties like API callers, database records, former programmers etc... so I am paranoid and defensive in approaches. Since you are on Java8 or later there is a bit cleaner approach than an if
block.
public String foo(@Nullable String mayBeNothing) {
return Optional.ofNullable(mayBeNothing).orElse("Really Nothing");
}
You can also throw some exception in there by swapping .orElse
to
orElseThrow(() -> new Exception("Dont' send a null"))
.
If you don't want to use @Nullable, which adds nothing functionally, why not just name the parameter with mayBe...
so your intention is clear.
To assign value of a text box whose id is "textbox" in JQuery please do the following
$("#textbox").get(0).value = "blah"
I'd do this one of two ways. Since you're setting your start and end dates in your t-sql code, i wouldn't ask for parameters in the stored proc
Option 1
Create Procedure [Test] AS
DECLARE @StartDate varchar(10)
DECLARE @EndDate varchar(10)
Set @StartDate = '201620' --Define start YearWeek
Set @EndDate = (SELECT CAST(DATEPART(YEAR,getdate()) AS varchar(4)) + CAST(DATEPART(WEEK,getdate())-1 AS varchar(2)))
SELECT
*
FROM
(SELECT DISTINCT [YEAR],[WeekOfYear] FROM [dbo].[DimDate] WHERE [Year]+[WeekOfYear] BETWEEN @StartDate AND @EndDate ) dimd
LEFT JOIN [Schema].[Table1] qad ON (qad.[Year]+qad.[Week of the Year]) = (dimd.[Year]+dimd.WeekOfYear)
Option 2
Create Procedure [Test] @StartDate varchar(10),@EndDate varchar(10) AS
SELECT
*
FROM
(SELECT DISTINCT [YEAR],[WeekOfYear] FROM [dbo].[DimDate] WHERE [Year]+[WeekOfYear] BETWEEN @StartDate AND @EndDate ) dimd
LEFT JOIN [Schema].[Table1] qad ON (qad.[Year]+qad.[Week of the Year]) = (dimd.[Year]+dimd.WeekOfYear)
Then run exec test '2016-01-01','2016-01-25'
You can also specify the font size relative to the base_size
included in themes such as theme_bw()
(where base_size
is 11) using the rel()
function.
For example:
ggplot(mtcars, aes(disp, mpg, col=as.factor(cyl))) +
geom_point() +
theme_bw() +
theme(legend.text=element_text(size=rel(0.5)))
There are mainly two ways to generate new component in Angular,
using ng g c <component_name>
, another way is that using ng generate component <component_name>
. using one of these commands new component can be generated.
can you try this :
function f (){
fname = $("input[name='fname']").val();
lname = $("input[name='fname']").val();
att=form.attr("action") ;
$.post(att ,{fname : fname , lname :lname}).done(function(data){
alert(data);
});
return true;
}
Use:

Always use the above command to enable to executing PowerShell in the current session.
H2CO3 is right, you can use a makefile with the CXXFLAGS set with -std=c++11 A makefile is a simple text file with instructions about how to compile your program. Create a new file named Makefile (with a capital M). To automatically compile your code just type the make command in a terminal. You may have to install make.
Here's a simple one :
CXX=clang++
CXXFLAGS=-g -std=c++11 -Wall -pedantic
BIN=prog
SRC=$(wildcard *.cpp)
OBJ=$(SRC:%.cpp=%.o)
all: $(OBJ)
$(CXX) -o $(BIN) $^
%.o: %.c
$(CXX) $@ -c $<
clean:
rm -f *.o
rm $(BIN)
It assumes that all the .cpp files are in the same directory as the makefile. But you can easily tweak your makefile to support a src, include and build directories.
Edit : I modified the default c++ compiler, my version of g++ isn't up-to-date. With clang++ this makefile works fine.
CORRELATED SUBQUERIES: Is evaluated for each row processed by the Main query. Execute the Inner query based on the value fetched by the Outer query. Continues till all the values returned by the main query are matched. The INNER Query is driven by the OUTER Query
Ex:
SELECT empno,fname,sal,deptid FROM emp e WHERE sal=(SELECT AVG(sal) FROM emp WHERE deptid=e.deptid)
The Correlated subquery specifically computes the AVG(sal)
for each department.
SUBQUERY: Runs first,executed once,returns values to be used by the MAIN Query. The OUTER Query is driven by the INNER QUERY
Before proceeding:
Install a proper mergetool. On Linux, I strongly suggest you to use meld:
sudo apt-get install meld
Configure your mergetool:
git config --global merge.tool meld
Then, iterate in the following way:
git cherry-pick ....
git mergetool
git cherry-pick --continue
To give the simplest answer I can think of:
Suppose we have a problem that takes a certain number of inputs, and has various potential solutions, which may or may not solve the problem for given inputs. A logic puzzle in a puzzle magazine would be a good example: the inputs are the conditions ("George doesn't live in the blue or green house"), and the potential solution is a list of statements ("George lives in the yellow house, grows peas, and owns the dog"). A famous example is the Traveling Salesman problem: given a list of cities, and the times to get from any city to any other, and a time limit, a potential solution would be a list of cities in the order the salesman visits them, and it would work if the sum of the travel times was less than the time limit.
Such a problem is in NP if we can efficiently check a potential solution to see if it works. For example, given a list of cities for the salesman to visit in order, we can add up the times for each trip between cities, and easily see if it's under the time limit. A problem is in P if we can efficiently find a solution if one exists.
(Efficiently, here, has a precise mathematical meaning. Practically, it means that large problems aren't unreasonably difficult to solve. When searching for a possible solution, an inefficient way would be to list all possible potential solutions, or something close to that, while an efficient way would require searching a much more limited set.)
Therefore, the P=NP problem can be expressed this way: If you can verify a solution for a problem of the sort described above efficiently, can you find a solution (or prove there is none) efficiently? The obvious answer is "Why should you be able to?", and that's pretty much where the matter stands today. Nobody has been able to prove it one way or another, and that bothers a lot of mathematicians and computer scientists. That's why anybody who can prove the solution is up for a million dollars from the Claypool Foundation.
We generally assume that P does not equal NP, that there is no general way to find solutions. If it turned out that P=NP, a lot of things would change. For example, cryptography would become impossible, and with it any sort of privacy or verifiability on the Internet. After all, we can efficiently take the encrypted text and the key and produce the original text, so if P=NP we could efficiently find the key without knowing it beforehand. Password cracking would become trivial. On the other hand, there's whole classes of planning problems and resource allocation problems that we could solve effectively.
You may have heard the description NP-complete. An NP-complete problem is one that is NP (of course), and has this interesting property: if it is in P, every NP problem is, and so P=NP. If you could find a way to efficiently solve the Traveling Salesman problem, or logic puzzles from puzzle magazines, you could efficiently solve anything in NP. An NP-complete problem is, in a way, the hardest sort of NP problem.
So, if you can find an efficient general solution technique for any NP-complete problem, or prove that no such exists, fame and fortune are yours.
if(isset($response->records))
print "we've got records!";
Although it is very old question, but as i didn't find a one liner, i made one.
# original numbers in list
l = [1, 2, 2, 3, 3, 3, 4]
# empty dictionary to hold pair of number and its count
d = {}
# loop through all elements and store count
[ d.update( {i:d.get(i, 0)+1} ) for i in l ]
print(d)
You could use a classmethod
or staticmethod
class Paul(object):
elems = []
@classmethod
def addelem(cls, e):
cls.elems.append(e)
@staticmethod
def addelem2(e):
Paul.elems.append(e)
Paul.addelem(1)
Paul.addelem2(2)
print(Paul.elems)
classmethod
has advantage that it would work with sub classes, if you really wanted that functionality.
module is certainly best though.
Use an empty element sized for the content as the background, and position the content over the blurred element.
#dialog_base{
background:white;
background:rgba(255,255,255,0.8);
position: absolute;
top: 40%;
left: 50%;
z-index: 50;
margin-left: -200px;
height: 200px;
width: 400px;
filter:blur(4px);
-o-filter:blur(4px);
-ms-filter:blur(4px);
-moz-filter:blur(4px);
-webkit-filter:blur(4px);
}
#dialog_content{
background: transparent;
position: absolute;
top: 40%;
left: 50%;
margin-left -200px;
overflow: hidden;
z-index: 51;
}
The background element can be inside of the content element, but not the other way around.
<div id='dialog_base'></div>
<div id='dialog_content'>
Some Content
<!-- Alternatively with z-index: <div id='dialog_base'></div> -->
</div>
This is not easy if the content is not always consistently sized, but it works.
var img = new Image();
img.onload = function(){
var height = img.height;

Use ViewChild with #localvariable as shown here,
<textarea #someVar id="tasknote"
name="tasknote"
[(ngModel)]="taskNote"
placeholder="{{ notePlaceholder }}"
style="background-color: pink"
(blur)="updateNote() ; noteEditMode = false " (click)="noteEditMode = false"> {{ todo.note }}
</textarea>
In component,
import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;
ngAfterViewInit()
{
this.el.nativeElement.focus();
}
import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;
constructor(private rd: Renderer) {}
ngAfterViewInit() {
this.rd.invokeElementMethod(this.el.nativeElement,'focus');
}
Please note from Angular v4.0.0-rc.3 (2017-03-10) few things have been changed.
Since Angular team will deprecate invokeElementMethod
, above code no longer can be used.
BREAKING CHANGES
since 4.0 rc.1:
rename RendererV2 to Renderer2
rename RendererTypeV2 to RendererType2
rename RendererFactoryV2 to RendererFactory2
import {ElementRef,Renderer2} from '@angular/core';
@ViewChild('someVar') el:ElementRef;
constructor(private rd: Renderer2) {}
ngAfterViewInit() {
console.log(this.rd);
this.el.nativeElement.focus(); //<<<=====same as oldest way
}
console.log(this.rd)
will give you following methods and you can see now invokeElementMethod
is not there. Attaching img as yet it is not documented.
NOTE: You can use following methods of Rendere2
with/without ViewChild variable to do so many things.
The client has a pre-seeded store of SSL certificate authorities' public keys. There must be a chain of trust from the certificate for the server up through intermediate authorities up to one of the so-called "root" certificates in order for the server to be trusted.
You can examine and/or alter the list of trusted authorities. Often you do this to add a certificate for a local authority that you know you trust - like the company you work for or the school you attend or what not.
The pre-seeded list can vary depending on which client you use. The big SSL certificate vendors insure that their root certs are in all the major browsers ($$$).
Monkey-in-the-middle attacks are "impossible" unless the attacker has the private key of a trusted root certificate. Since the corresponding certificates are widely deployed, the exposure of such a private key would have serious implications for the security of eCommerce generally. Because of that, those private keys are very, very closely guarded.
ocLazyLoad allows to lazily load scripts in the templates/views via routers (e.g. ui-router). Here is a sniplet
$stateProvider.state('parent', {
url: "/",
resolve: {
loadMyService: ['$ocLazyLoad', function($ocLazyLoad) {
return $ocLazyLoad.load('js/ServiceTest.js');
}]
}
})
.state('parent.child', {
resolve: {
test: ['loadMyService', '$ServiceTest', function(loadMyService, $ServiceTest) {
// you can use your service
$ServiceTest.doSomething();
}]
}
});

Make sure that the RSA host key and the IP of the bitbucket server is added to the 'known hosts' file. The contents should look like

Remember to change ownership to Jenkins for all the files in /var/lib/jenkins/.ssh/
Here is a simplified function that returns a boolean and has no output pushed to stdout:
import subprocess, platform
def pingOk(sHost):
try:
output = subprocess.check_output("ping -{} 1 {}".format('n' if platform.system().lower()=="windows" else 'c', sHost), shell=True)
except Exception, e:
return False
return True
You need to use command:
git config --global core.editor "'C:\Program Files\Microsoft VS Code\code.exe' -n -w"
Make sure you can start your editor from Git Bash
If you want to use Code.exe with short path, you can do this by adding the following line to your .bash_profile:
alias vscode="C:/Program\ Files/Microsoft\ VS\ Code/Code.exe"
And now, you can call it using only vscode
command(or whatever you named it)
Some additional info:
Setup will add Visual Studio Code to your %PATH%, so from the console you can type 'code' to open VS Code on that folder. You will need to restart your console after the installation for the change to the %PATH% environmental variable to take effect.

.It's easy to create a .NET Windows GUI in C++.
See the following tutorial from MSDN. You can download everything you need (Visual C++ Express) for free.
Of course you tie yourself to .NET, but if you're just playing around or only need a Windows application you'll be fine (most people still have Windows...for now).
Codeigniter is an MVC (Model - View - Controller) framework. It's really not a good idea to call a function from the view. The view should be used just for presentation, and all your logic should be happening before you get to the view in the controllers and models.
A good start for clarifying the best practice is to follow this tutorial:
https://codeigniter.com/user_guide/tutorial/index.html
It's simple, but it really lays out an excellent how-to.
I hope this helps!

pandas 0.21 introduces new functions for Parquet:
pd.read_parquet('example_pa.parquet', engine='pyarrow')
or
pd.read_parquet('example_fp.parquet', engine='fastparquet')
The above link explains:
These engines are very similar and should read/write nearly identical parquet format files. These libraries differ by having different underlying dependencies (fastparquet by using numba, while pyarrow uses a c-library).
As doc says also keep in mind the correct value combination:
The setting must be one of the values listed in the following table, or a combination of one "state..." value plus one "adjust..." value. Setting multiple values in either group — multiple "state..." values, for example — has undefined results. Individual values are separated by a vertical bar (|). For example:
<activity android:windowSoftInputMode="stateVisible|adjustResize" . . . >
For dynamic arrays (malloc or C++ new) you need to store the size of the array as mentioned by others or perhaps build an array manager structure which handles add, remove, count, etc. Unfortunately C doesn't do this nearly as well as C++ since you basically have to build it for each different array type you are storing which is cumbersome if you have multiple types of arrays that you need to manage.
For static arrays, such as the one in your example, there is a common macro used to get the size, but it is not recommended as it does not check if the parameter is really a static array. The macro is used in real code though, e.g. in the Linux kernel headers although it may be slightly different than the one below:
#if !defined(ARRAY_SIZE)
#define ARRAY_SIZE(x) (sizeof((x)) / sizeof((x)[0]))
#endif
int main()
{
int days[] = {1,2,3,4,5};
int *ptr = days;
printf("%u\n", ARRAY_SIZE(days));
printf("%u\n", sizeof(ptr));
return 0;
}
You can google for reasons to be wary of macros like this. Be careful.
If possible, the C++ stdlib such as vector which is much safer and easier to use.
A subtle alternative to MaxNoe's answer where you aren't explicitly setting the ticks but instead setting the cadence.
import matplotlib.pyplot as plt
from matplotlib.ticker import (AutoMinorLocator, MultipleLocator)
fig, ax = plt.subplots(figsize=(10, 8))
# Set axis ranges; by default this will put major ticks every 25.
ax.set_xlim(0, 200)
ax.set_ylim(0, 200)
# Change major ticks to show every 20.
ax.xaxis.set_major_locator(MultipleLocator(20))
ax.yaxis.set_major_locator(MultipleLocator(20))
# Change minor ticks to show every 5. (20/4 = 5)
ax.xaxis.set_minor_locator(AutoMinorLocator(4))
ax.yaxis.set_minor_locator(AutoMinorLocator(4))
# Turn grid on for both major and minor ticks and style minor slightly
# differently.
ax.grid(which='major', color='#CCCCCC', linestyle='--')
ax.grid(which='minor', color='#CCCCCC', linestyle=':')
I had a similar issue which i solved by making two changes
added below entry in application.yaml file
spring:
jackson:
serialization.write_dates_as_timestamps: false
add below two annotations in pojo
sample example
import com.fasterxml.jackson.databind.annotation.JsonDeserialize;
import com.fasterxml.jackson.databind.annotation.JsonSerialize;
public class Customer {
//your fields ...
@JsonDeserialize(using = LocalDateDeserializer.class)
@JsonSerialize(using = LocalDateSerializer.class)
protected LocalDate birthdate;
}
then the following json requests worked for me
{
"birthdate": "2019-11-28"
}
{
"birthdate":[2019,11,18]
}
Hope it helps!!

i++
is the standard use of a loop, but not the only way. Try incrementing by 3 each time:
for (int i = 0; i < theData.Length - 2; i+=3)
{
// use theData[i], theData[i+1], theData[i+2]
}
${var@Q}
Under bash, you could store your variable content with Parameter Expansion's @
command for Parameter transformation:
${parameter@operator} Parameter transformation. The expansion is either a transforma- tion of the value of parameter or information about parameter itself, depending on the value of operator. Each operator is a single letter: Q The expansion is a string that is the value of parameter quoted in a format that can be reused as input. ... A The expansion is a string in the form of an assignment statement or declare command that, if evaluated, will recreate parameter with its attributes and value.
Sample:
$ var=$'Hello\nGood world.\n'
$ echo "$var"
Hello
Good world.
$ echo "${var@Q}"
$'Hello\nGood world.\n'
$ echo "${var@A}"
var=$'Hello\nGood world.\n'
There is a special printf
format directive (%q
) built for this kind of request:
printf [-v var] format [arguments]
%q causes printf to output the corresponding argument in a format that can be reused as shell input.
read foo
Hello world
printf "%q\n" "$foo"
Hello\ world
printf "%q\n" $'Hello world!\n'
$'Hello world!\n'
This could be used through variables too:
printf -v var "%q" "$foo
"
echo "$var"
$'Hello world\n'
Note that all bytes from 128 to 255 have to be escaped.
for i in {0..127} ;do
printf -v var \\%o $i
printf -v var $var
printf -v res "%q" "$var"
esc=E
[ "$var" = "$res" ] && esc=-
printf "%02X %s %-7s\n" $i $esc "$res"

Where first field is hexa value of byte, second contain E
if character need to be escaped and third field show escaped presentation of character.
,
?You could see some characters that don't always need to be escaped, like ,
, }
and {
.
So not always but sometime:
echo test 1, 2, 3 and 4,5.
test 1, 2, 3 and 4,5.
or
echo test { 1, 2, 3 }
test { 1, 2, 3 }
but care:
echo test{1,2,3}
test1 test2 test3
echo test\ {1,2,3}
test 1 test 2 test 3
echo test\ {\ 1,\ 2,\ 3\ }
test 1 test 2 test 3
echo test\ {\ 1\,\ 2,\ 3\ }
test 1, 2 test 3
Java implementation contains utilities classes java.util.Arrays and java.util.Collections both of them contains static factory methods, examples of it and how to use :
Arrays.asList("1","2","3")
Collections.synchronizedList(..), Collections.emptyList(), Collections.unmodifiableList(...)
(Only some examples, could check javadocs for mor methods examples https://docs.oracle.com/javase/8/docs/api/java/util/Collections.html)
Also java.lang.String class have such static factory methods:
String.format(...), String.valueOf(..), String.copyValueOf(...)
Check whether your config string is okay:
Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=9999
I just had this issue today, and in my case it was because there was an invisible character in the jpda config parameter.
To be precise, I had dos line endings in my setenv.sh file on tomcat, causing a carriage-return character right after 'dt_socket'
To get all the messages stored for the topic you can seek the consumer to the beginning and end of the stream for each partition and sum the results
List<TopicPartition> partitions = consumer.partitionsFor(topic).stream()
.map(p -> new TopicPartition(topic, p.partition()))
.collect(Collectors.toList());
consumer.assign(partitions);
consumer.seekToEnd(Collections.emptySet());
Map<TopicPartition, Long> endPartitions = partitions.stream()
.collect(Collectors.toMap(Function.identity(), consumer::position));
consumer.seekToBeginning(Collections.emptySet());
System.out.println(partitions.stream().mapToLong(p -> endPartitions.get(p) - consumer.position(p)).sum());
The first thing that comes to my mind is a one-liner regex:
var pageNum = $("#specificLink").attr("href").match(/page=([0-9]+)/)[1];
Warning
If you run PowerShell from a cmd.exe window created by Powershell, the 2nd instance no longer waits for jobs to complete.
cmd> PowerShell
PS> Start-Process cmd.exe -Wait
Now from the new cmd window, run PowerShell again and within it start a 2nd cmd window: cmd2> PowerShell
PS> Start-Process cmd.exe -Wait
PS>
The 2nd instance of PowerShell no longer honors the -Wait request and ALL background process/jobs return 'Completed' status even thou they are still running !
I discovered this when my C# Explorer program is used to open a cmd.exe window and PS is run from that window, it also ignores the -Wait request. It appears that any PowerShell which is a 'win32 job' of cmd.exe fails to honor the wait request.
I ran into this with PowerShell version 3.0 on windows 7/x64
For DSA keys, use

to print the public keys, then
openssl dsa -in dsa.key -modulus -noout
to display the public keys corresponding to a private key, then compare them.
I don't know about y'all but for my own lazy purposes I just got the text fields from 'document' by ID and set the values as parameters to my back-end JS function:

It works just fine.
You can also create a new document from MongoDB compass or using command and set the specific _id
value that you want.
I'm quite a beginner in Python and I found the answer of Anand was very good but quite complicated to me, so I try to reformulate :
1) insert
and append
methods are not specific to sys.path
and as in other languages they add an item into a list or array and :
* append(item)
add item
to the end of the list,
* insert(n, item)
inserts the item
at the nth position in the list (0
at the beginning, 1
after the first element, etc ...).
2) As Anand said, python search the import files in each directory of the path in the order of the path, so :
* If you have no file name collisions, the order of the path has no impact,
* If you look after a function already defined in the path and you use append
to add your path, you will not get your function but the predefined one.
But I think that it is better to use append
and not insert
to not overload the standard behaviour of Python, and use non-ambiguous names for your files and methods.
Type this code in your editor so that it can import necessary modules.
query.setOnEditorActionListener(new TextView.OnEditorActionListener() {
@Override
public boolean onEditorAction(TextView textView, int actionId, KeyEvent keyEvent) {
if(actionId == EditorInfo.IME_ACTION_DONE
|| keyEvent.getAction() == KeyEvent.ACTION_DOWN
|| keyEvent.getAction() == KeyEvent.KEYCODE_ENTER) {
// Put your function here ---!
return true;
}
return false;
}
});
From ?read.table
: The number of data columns is determined by looking at the first five lines of input (or the whole file if it has less than five lines), or from the length of col.names if it is specified and is longer. This could conceivably be wrong if fill or blank.lines.skip are true, so specify col.names if necessary.
So, perhaps your data file isn't clean. Being more specific will help the data import:
d = read.table("foobar.txt",
sep="\t",
col.names=c("id", "name"),
fill=FALSE,
strip.white=TRUE)
will specify exact columns and fill=FALSE
will force a two column data frame.
If you're looking to do something with a list of files, you can use find combined with the bash $()
construct (better than backticks since it's allowed to nest).
for example, say you're at the top level of your project directory and you want a list of all C files starting with "btree". The command:
find . -type f -name 'btree*.c'
will return a list of them. But this doesn't really help with doing something with them.
So, let's further assume you want to search all those file for the string "ERROR" or edit them all. You can execute one of:
grep ERROR $(find . -type f -name 'btree*.c')
vi $(find . -type f -name 'btree*.c')
to do this.
I found this worked in my scenario.
The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.
$.get("urlToCheck.com").done(function () {
alert("success");
}).fail(function () {
alert("failed.");
});
I'd suggest a better solution is to give the --add-host NAME:IP
argument to docker run when starting the container. That will update the /etc/hosts/
file without any need to become root.
Otherwise, you can override the the USER
setting by giving the -u USER
flag to docker run
. I would advise against this however, as you shouldn't really be changing things in a running container. Instead, make your changes in a Dockerfile and build a new image.
I'm guessing you didn't run this command after the commit failed so just actually run this to create the remote :
git remote add origin https://github.com/VijayNew/NewExample.git
And the commit failed because you need to git add
some files you want to track.
On windows I tried to do quit git bash and re-run but didn't work, finally me(frustated) did a restart and it worked the next time :)

Yes, Python does support Short-circuit evaluation, minimal evaluation, or McCarthy evaluation for Boolean operators. It is used to reduce the number of evaluations for computing the output of boolean expression. Example -
Base Functions
def a(x):
print('a')
return x
def b(x):
print('b')
return x
AND
if(a(True) and b(True)):
print(1,end='\n\n')
if(a(False) and b(True)):
print(2,end='\n\n')
AND-OUTPUT
a
b
1
a
OR
if(a(True) or b(False)):
print(3,end='\n\n')
if(a(False) or b(True)):
print(4,end='\n\n')
OR-OUTPUT
a
3
a
b

I use pip freeze
to get the packages I need into a requirements.txt

The context classes for badge
are indeed removed from Bootstrap 3, so you'd have to add some custom CSS to create the same effect like...
.badge-important{background-color:#b94a48;}
You can use List as a classifier for many fields, but you need wrap null values into Optional:
Function<String, List> classifier = (item) -> List.of(
item.getFieldA(),
item.getFieldB(),
Optional.ofNullable(item.getFieldC())
);
Map<List, List<Item>> grouped = items.stream()
.collect(Collectors.groupingBy(classifier));
I had the same question as the OP, and none of those answers fitted my needs. I needed a simple condition, for a simple need.
Here's my answer:
if ($("#myoverflowingelement").prop('scrollWidth') > $("#myoverflowingelement").width() ) {
alert("this element is overflowing !!");
}
else {
alert("this element is not overflowing!!");
}
Also, you can change scrollWidth
by scrollHeight
if you need to test the either case.
You can sort the dataFrame by count and then remove duplicates. I think it's easier:

1) In this case they use a uid and it's not a JWT. When they refresh the token they send the refresh token and the user. If you implement it as a JWT, you don't need to send the user, because it would inside the JWT.
2) They implement this in a separated document (table). It has sense to me because a user can be logged in in different client applications and it could have a refresh token by app. If the user lose a device with one app installed, the refresh token of that device could be invalidated without affecting the other logged in devices.
3) In this implementation it response to the log in method with both, access token and refresh token. It seams correct to me.
Simply use :
mapA.equals(mapB);
Compares the specified object with this map for equality. Returns true if the given object is also a map and the two maps represent the same mappings
;with cte as
(
Select Department, Max(salary) as MaxSalary
from test
group by department
)
select t.* from test t join cte c on c.department=t.department
where t.salary=c.MaxSalary;

Nodejs is a scripting language (like Python or Ruby, and unlike PHP or C++). To run your code, you need to enter a command in the terminal / shell / command prompt. Look for an application shortcut in your operating system by one of those names.
The command to run in the terminal will be
node server.js
But you will first need to browse in the terminal to the same folder as the file server.js
. The syntax for using the terminal varies by operating system, look for its documentation.
Change the cell type to Markdown in the menu bar, from Code
to Markdown
. Currently in Notebook 4.x
, the keyboard shortcut for such an action is: Esc
(for command mode), then m
(for markdown).
You can even pass parameters to the sed command:
test.sh
#!/bin/bash
echo "-> start"
for i in $(seq 5); do
# passing parameters to sed
j=$(($i+3))
sed -i "${j}s/.*/replaced by '$i'!/" output.dat
done
echo "-> finished"
exit
orignial output.dat:
a
b
c
d
e
f
g
h
i
j
Executing ./test.sh gives the new output.dat
a
b
c
replaced by '1'!
replaced by '2'!
replaced by '3'!
replaced by '4'!
replaced by '5'!
i
j
You should use <h:panelGroup ...>
tag with attribute rendered
. If you set true
to rendered, the content of <h:panelGroup ...>
won't be shown. Your XHTML file should have something like this:
<h:panelGroup rendered="#{userBean.showPassword}">
<h:outputText id="password" value="#{userBean.password}"/>
</h:panelGroup>
UserBean.java:
import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
@ManagedBean
@SessionScoped
public class UserBean implements Serializable{
private boolean showPassword = false;
private String password = "";
public boolean isShowPassword(){
return showPassword;
}
public void setPassword(password){
this.password = password;
}
public String getPassword(){
return this.password;
}
}
querySelectorAll returns a NodeList which has its own forEach method:
document.querySelectorAll('input').forEach( input => {
// ...
});
getElementsByTagName now returns an HTMLCollection instead of a NodeList. So you would first need to convert it to an array to have access to methods like map and forEach:
Array.from(document.getElementsByTagName('input')).forEach( input => {
// ...
});
I like this:
if (wlocation !== undefined)
But if you prefer the second way wouldn't be as you posted. It would be:
if (typeof wlocation !== "undefined")
You can set any pointer to NULL
, though NULL
is simply defined as 0 in C++:
myObject *foo = NULL;
Also note that NULL
is defined if you include standard headers, but is not built into the language itself. If NULL
is undefined, you can use 0 instead, or include this:
#ifndef NULL
#define NULL 0
#endif
As an aside, if you really want to set an object, not a pointer, to NULL
, you can read about the Null Object Pattern.
setInterval
fires again and again in intervals, while setTimeout
only fires once.
See reference at MDN.
I've seen this a couple times, and it is usually fixed by running a repair on .NET Framework (whichever version the application is trying to use).
Fixed it...

To continue a statement from one line to the next, type a space followed by the line-continuation character [the underscore character on your keyboard (_)].
You can break a line at an operator, list separator, or period.
Simple solution (ES6)
If you don't have duplicate element
Array.prototype.remove = function(elem) {
var indexElement = this.findIndex(el => el === elem);
if (indexElement != -1)
this.splice(indexElement, 1);
return this;
};
To merge the sets in the array Sets, you can do
var Sets = [set1, set2, set3];
var merged = new Set([].concat(...Sets.map(set => Array.from(set))));
It is slightly mysterious to me why the following, which should be equivalent, fails at least in Babel:
var merged = new Set([].concat(...Sets.map(Array.from)));
Try calling read_csv
with encoding='latin1'
, encoding='iso-8859-1'
or encoding='cp1252'
(these are some of the various encodings found on Windows).
Using constants allows to combine multiple fields for verification:

As a beginner to android development, my issue wasn't any of these solutions. I had several problems.
Firstly, I didn't realise that you had to use the bug symbol to use the debugger to hit breakpoints.
Then I was silently getting an error in my on click listener, I was trying to pass something to a method, but the method required a float value.
However in the ide, the method was shown as unused. It wasn't until I cast the value that the method was shown in the correct colour and wasn't marked as unused anymore.
Not sure why I didn't get an error from trying to use a method with the wrong type ?
Also I had to add the android:debuggable="true"
to my manifest to get debugging to hit breakpoints.
There are a number of ways you can do this:
How to implement Idea #5? Well, one way is to first create an interface:
public interface ThreadCompleteListener {
void notifyOfThreadComplete(final Thread thread);
}
then create the following class:
public abstract class NotifyingThread extends Thread {
private final Set<ThreadCompleteListener> listeners
= new CopyOnWriteArraySet<ThreadCompleteListener>();
public final void addListener(final ThreadCompleteListener listener) {
listeners.add(listener);
}
public final void removeListener(final ThreadCompleteListener listener) {
listeners.remove(listener);
}
private final void notifyListeners() {
for (ThreadCompleteListener listener : listeners) {
listener.notifyOfThreadComplete(this);
}
}
@Override
public final void run() {
try {
doRun();
} finally {
notifyListeners();
}
}
public abstract void doRun();
}
and then each of your Threads will extend NotifyingThread
and instead of implementing run()
it will implement doRun()
. Thus when they complete, they will automatically notify anyone waiting for notification.
Finally, in your main class -- the one that starts all the Threads (or at least the object waiting for notification) -- modify that class to implement ThreadCompleteListener
and immediately after creating each Thread add itself to the list of listeners:
NotifyingThread thread1 = new OneOfYourThreads();
thread1.addListener(this); // add ourselves as a listener
thread1.start(); // Start the Thread
then, as each Thread exits, your notifyOfThreadComplete
method will be invoked with the Thread instance that just completed (or crashed).
Note that better would be to implements Runnable
rather than extends Thread
for NotifyingThread
as extending Thread is usually discouraged in new code. But I'm coding to your question. If you change the NotifyingThread
class to implement Runnable
then you have to change some of your code that manages Threads, which is pretty straightforward to do.
