I was struggling with similar problem (with mail) in one of my git's post_receive hooks and finally I found out, that sendmail actually works better for that kind of things, especially if you know a bit of how e-mails are constructed (and it seems like you know). I know this answer comes very late, but maybe it will be of some use to others too. I made use of heredoc operator and use of the feature, that it expands variables, so it can also run inlined scripts. Just check this out (bash script):
#!/bin/bash
recipients=(
'[email protected]'
'[email protected]'
# '[email protected]'
);
sender='[email protected]';
subject='Oh, who really cares, seriously...';
sendmail -t <<-MAIL
From: ${sender}
`for r in "${recipients[@]}"; do echo "To: ${r}"; done;`
Subject: ${subject}
Content-Type: text/html; charset=UTF-8
<html><head><meta charset="UTF-8"/></head>
<body><p>Ladies and gents, here comes the report!</p>
<pre>`mysql -u ***** -p***** -H -e "SELECT * FROM users LIMIT 20"`</pre>
</body></html>
MAIL
Note of backticks in the MAIL part to generate some output and remember, that <<-
operator strips only tabs (not spaces) from the beginning of lines, so in that case copy-paste will not work (you need to replace indentation with proper tabs). Or use <<
operator and make no indentation at all. Hope this will help someone. Of course you can use backticks outside o MAIL part and save the output into some variable, that you can later use in the MAIL part — matter of taste and readability. And I know, #!/bin/bash
does not always work on every system.
I made the following code so that even beginners can understand. Just copy the code and read comments. Note that message to be send is declared as a global variable which you can change just before sending the message. General changes can be done in Handler function.

As I understand it, you want the server be able to send messages through from client 1 to client 2. You cannot directly connect two clients because one of the two ends of a WebSocket connection needs to be a server.
This is some pseudocodish JavaScript:
Client:
var websocket = new WebSocket("server address");
websocket.onmessage = function(str) {
console.log("Someone sent: ", str);
};
// Tell the server this is client 1 (swap for client 2 of course)
websocket.send(JSON.stringify({
id: "client1"
}));
// Tell the server we want to send something to the other client
websocket.send(JSON.stringify({
to: "client2",
data: "foo"
}));
Server:
var clients = {};
server.on("data", function(client, str) {
var obj = JSON.parse(str);
if("id" in obj) {
// New client, add it to the id/client object
clients[obj.id] = client;
} else {
// Send data to the client requested
clients[obj.to].send(obj.data);
}
});
When you select a radio button and click on a submit button, you need to handle the submission of any selected values in your php code using $_POST[]
For example:
if your radio button is:
<input type="radio" name="rdb" value="male"/>
then in your php code you need to use:
$rdb_value = $_POST['rdb'];
The trick is to know the content id of the Image mime part when building the html body part. It boils down to making the img tag
https://github.com/horde/horde/blob/master/kronolith/lib/Kronolith.php
Look at the function buildMimeMessage for a working example.
I don't think it's a good idea to caculate yourself.
If you just want a pretty output, just covert it into str
with str()
function or directly print()
it.
And if there's further usage of the hours and minutes, you can parse it to datetime
object use datetime.strptime()
(and extract the time part with datetime.time()
mehtod), for example:
import datetime
delta = datetime.timedelta(seconds=10000)
time_obj = datetime.datetime.strptime(str(delta),'%H:%M:%S').time()
The following example demonstrates how to POST a JSON via WebClient.UploadString Method:
var vm = new { k = "1", a = "2", c = "3", v= "4" };
using (var client = new WebClient())
{
var dataString = JsonConvert.SerializeObject(vm);
client.Headers.Add(HttpRequestHeader.ContentType, "application/json");
client.UploadString(new Uri("http://www.contoso.com/1.0/service/action"), "POST", dataString);
}
Prerequisites: Json.NET library
In Python 3.8 version there is a new metadata

Might help someone else : I encountered the same kind of issues while I had done some "copy-paste" from a side Microsoft Word document, where I took notes, to my shell script(s).
Re-writing, manually, the exact same code in the script just solved this.
It was quite un-understandable at first, I think Word's hidden characters and/or formatting were the issue. Obvious but not see-able ... I lost about one hour on this (I'm no shell expert, as you might guess ...)
Wildcards aren't expanded inside quoted strings. And when wildcard is expanded, it's returned unchanged if there are no matches, it doesn't expand into an empty string. Try:
output="$(ls home/edward/bank1/fiche/Test* 2>/dev/null)"
if [ -n "$output" ]
then echo "Found one"
else echo "Found none"
fi
If the wildcard expanded to filenames, ls
will list them on stdout
; otherwise it will print an error on stderr
, and nothing on stdout. The contents of stdout
are assigned to output
.
if [ -n "$output" ]
tests whether $output
contains anything.
Another way to write this would be:
if [ $(ls home/edward/bank1/fiche/Test* 2>/dev/null | wc -l) -gt 0 ]
Why this error?
You broke the one definition rule and hence the linking error.
Suggested Solutions:
If you need the same named variable in the two cpp files then You need to use Nameless namespace(Anonymous Namespace) to avoid the error.
namespace
{
int k;
}
If you need to share the same variable across multiple files then you need to use extern
.
A.h
extern int k;
A.cpp
#include "A.h"
int k = 0;
B.cpp
#include "A.h"
//Use `k` anywhere in the file
NULL
is not guaranteed to be 0 -- its exact value is architecture-dependent. Most major architectures define it to (void*)0
.
'\0'
will always equal 0, because that is how byte 0 is encoded in a character literal.
I don't remember whether C compilers are required to use ASCII -- if not, '0'
might not always equal 48. Regardless, it's unlikely you'll ever encounter a system which uses an alternative character set like EBCDIC unless you're working on very obscure systems.
The sizes of the various types will differ on 64-bit systems, but the integer values will be the same.
Some commenters have expressed doubt that NULL be equal to 0, but not be zero. Here is an example program, along with expected output on such a system:
#include <stdio.h>
int main () {
size_t ii;
int *ptr = NULL;
unsigned long *null_value = (unsigned long *)&ptr;
if (NULL == 0) {
printf ("NULL == 0\n"); }
printf ("NULL = 0x");
for (ii = 0; ii < sizeof (ptr); ii++) {
printf ("%02X", null_value[ii]); }
printf ("\n");
return 0;
}
That program could print:
NULL == 0
NULL = 0x00000001
When we save anything in Django admin two steps validation happens, on Django level and on Database level. We can't save text in a number field.
Database has data type NULL, it's nothing. When Django creates columns in the database it specifies that they can't be empty. And if you will try to save NULL you will get the database error.
Also on Django-Admin level, all fields are required by default, you can't save blank field, Django will throw you an error.
So, if you want to save blank field you need to allow it on Django and Database level. blank=True - will allow empty field in admin panel null=True - will allow saving NULL to the database column.

You can easily create a Stream
out of an Iterable
or Iterator
:
public static <T> Stream<T> stream(Iterable<T> iterable) {
return StreamSupport.stream(
Spliterators.spliteratorUnknownSize(
iterable.iterator(),
Spliterator.ORDERED
),
false
);
}
Search for setTextAppearance
or also setTextTypeface
. There is similar question on stackoverflow: How to change a TextView's style at runtime
First of all get a string from an EDITTEXT and then convert this string into integer like
String no=myTxt.getText().toString(); //this will get a string
int no2=Integer.parseInt(no); //this will get a no from the string
In addition to using KeyListener (as shown by others' answers), sometimes you have to ensure that the JComponent you are using is Focusable. This can be set by adding this to your component(if you are subclassing):
@Override
public void setFocusable(boolean b) {
super.setFocusable(b);
}
And by adding this to your constructor:
setFocusable(true);
Or, if you are calling the function from a parent class/container:
JComponent childComponent = new JComponent();
childComponent.setFocusable(true);
And then doing all the KeyListener stuff mentioned by others.
I tried a few things in this scenario.
I removed ios and installed many times. Went down the path of deleting Splash screens to no avail! Bitcode on/off so many times.
However, after selecting a iOS provisioning team, and running pod update
inside ./platforms/ios
, I am pleased to announce this resolved my problems.
Hopefully you can try the same and get some resolution?
You should check that the spring.handlers
and spring.schemas
files are on the classpath and have the right content.
This can be done with ClassLoader.getResource(..)
. You can run the method with a remote debugger in the runtime environment. The extensible XML authoring setup is described in the Spring Reference B.5. Registering the handler and the schema.
Normally, the files should be in the spring jar (springframework.jar/META-INF/) and on the classpath when Spring can be initiated.
I had the same issue on OSX Mavericks, it turned out that Sophos anti-virus was blocking certain requests, once I uninstalled it the issue went away.
If you think that it might be caused by an extension one easy way to try and test this is to open chrome with the '--disable-extensions
flag to see if it fixes the problem. If that doesn't fix it consider looking beyond the browser to see if any other application might be causing the problem, specifically security apps which can affect requests.
It will order first, then get the first 20. A database will also process anything in the WHERE
clause before ORDER BY
.
No fancy tricks needed:
for i in *.java; do
[ -f "$i" ] || break
...
done
The guard ensures that if there are no matching files, the loop will exit without trying to process a non-existent file name *.java
. In bash
(or shells supporting something similar), you can use the nullglob
option
to simply ignore a failed match and not enter the body of the loop.
shopt -s nullglob
for i in *.java; do
...
done
You can use the null coalescing double question marks to test for nulls in a string or other nullable value type:
textBox1.Text = s ?? "Is null";
The operator '??' asks if the value of 's' is null and if not it returns 's'; if it is null it returns the value on the right of the operator.
More info here: https://msdn.microsoft.com/en-us/library/ms173224.aspx
And also worth noting there's a null-conditional operator ?. and ?[ introduced in C# 6.0 (and VB) in VS2015
textBox1.Text = customer?.orders?[0].description ?? "n/a";
This returns "n/a" if description is null, or if the order is null, or if the customer is null, else it returns the value of description.
More info here: https://msdn.microsoft.com/en-us/library/dn986595.aspx
IMHO, the most elegant way is using the Java API for JSON Processing (JSON-P), one of the JavaEE standards that conforms to the JSR 374.
try(StringReader sr = new StringReader(jsonStrn)) {
Json.createReader(sr).readObject();
} catch(JsonParsingException e) {
System.out.println("The given string is not a valid json");
e.printStackTrace();
}
Using Maven, add the dependency on JSON-P:
<dependency>
<groupId>org.glassfish</groupId>
<artifactId>javax.json</artifactId>
<version>1.1.4</version>
</dependency>
Visit the JSON-P official page for more informations.
You must dereference the iterator in order to retrieve the member of your set.
std::set<unsigned long>::iterator it;
for (it = SERVER_IPS.begin(); it != SERVER_IPS.end(); ++it) {
u_long f = *it; // Note the "*" here
}
If you have C++11 features, you can use a range-based for loop:
for(auto f : SERVER_IPS) {
// use f here
}
I just found a new trick to center a box in the middle of the screen even if you don't have fixed dimensions. Let's say you would like a box 60% width / 60% height. The way to make it centered is by creating 2 boxes: a "container" box that position left: 50% top :50%, and a "text" box inside with reverse position left: -50%; top :-50%;
It works and it's cross browser compatible.

if(selectOptions.length >0)
{
var resultString = "";
resultString = selectOptions.text();
}
});
I suggest you should use one of the mappers' libraries: Mapstruct, ModelMapper, etc. With Mapstruct your mapper will look like:
@Mapper
public interface UserMapper {
UserMapper INSTANCE = Mappers.getMapper( UserMapper.class );
UserDTO toDto(User user);
}
The real object with all getters and setters will be automatically generated from this interface. You can use it like:
UserDTO userDTO = UserMapper.INSTANCE.toDto(user);
You can also add some logic for your activeText filed using @AfterMapping annotation.
You can remove an entry from your map by explicitly assigning it to 'undefined'. As in your case:
myArray["lastname"] = undefined;
You must convert to List
as shown below:
String[] valores = hierarquia.split(".");
List<String> lista = Arrays.asList(valores);
String jpqlQuery = "SELECT a " +
"FROM AcessoScr a " +
"WHERE a.scr IN :param ";
Query query = getEntityManager().createQuery(jpqlQuery, AcessoScr.class);
query.setParameter("param", lista);
List<AcessoScr> acessos = query.getResultList();
Here is a little utility class that I created:
import java.io.File;
import java.io.FilenameFilter;
import java.util.HashSet;
import java.util.Iterator;
import java.util.Set;
/**
* Convenience utility to create a FilenameFilter, based on a list of extensions
*/
public class FileExtensionFilter implements FilenameFilter {
private Set<String> exts = new HashSet<String>();
/**
* @param extensions
* a list of allowed extensions, without the dot, e.g.
* <code>"xml","html","rss"</code>
*/
public FileExtensionFilter(String... extensions) {
for (String ext : extensions) {
exts.add("." + ext.toLowerCase().trim());
}
}
public boolean accept(File dir, String name) {
final Iterator<String> extList = exts.iterator();
while (extList.hasNext()) {
if (name.toLowerCase().endsWith(extList.next())) {
return true;
}
}
return false;
}
}
Usage:
String[] files = new File("myfile").list(new FileExtensionFilter("pdf", "zip"));
--- Shameless plug ---
I have added this function to a library I created
vanillajs-browser-helpers: https://github.com/Tokimon/vanillajs-browser-helpers/blob/master/inView.js
-------------------------------
Well BenM stated, you need to detect the height of the viewport + the scroll position to match up with your top position. The function you are using is ok and does the job, though its a bit more complex than it needs to be.
If you don't use jQuery
then the script would be something like this:
function posY(elm) {
var test = elm, top = 0;
while(!!test && test.tagName.toLowerCase() !== "body") {
top += test.offsetTop;
test = test.offsetParent;
}
return top;
}
function viewPortHeight() {
var de = document.documentElement;
if(!!window.innerWidth)
{ return window.innerHeight; }
else if( de && !isNaN(de.clientHeight) )
{ return de.clientHeight; }
return 0;
}
function scrollY() {
if( window.pageYOffset ) { return window.pageYOffset; }
return Math.max(document.documentElement.scrollTop, document.body.scrollTop);
}
function checkvisible( elm ) {
var vpH = viewPortHeight(), // Viewport Height
st = scrollY(), // Scroll Top
y = posY(elm);
return (y > (vpH + st));
}
Using jQuery is a lot easier:
function checkVisible( elm, evalType ) {
evalType = evalType || "visible";
var vpH = $(window).height(), // Viewport Height
st = $(window).scrollTop(), // Scroll Top
y = $(elm).offset().top,
elementHeight = $(elm).height();
if (evalType === "visible") return ((y < (vpH + st)) && (y > (st - elementHeight)));
if (evalType === "above") return ((y < (vpH + st)));
}
This even offers a second parameter. With "visible" (or no second parameter) it strictly checks whether an element is on screen. If it is set to "above" it will return true when the element in question is on or above the screen.
See in action: http://jsfiddle.net/RJX5N/2/
I hope this answers your question.
-- IMPROVED VERSION--
This is a lot shorter and should do it as well:
function checkVisible(elm) {
var rect = elm.getBoundingClientRect();
var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
return !(rect.bottom < 0 || rect.top - viewHeight >= 0);
}
with a fiddle to prove it: http://jsfiddle.net/t2L274ty/1/
And a version with threshold
and mode
included:
function checkVisible(elm, threshold, mode) {
threshold = threshold || 0;
mode = mode || 'visible';
var rect = elm.getBoundingClientRect();
var viewHeight = Math.max(document.documentElement.clientHeight, window.innerHeight);
var above = rect.bottom - threshold < 0;
var below = rect.top - viewHeight + threshold >= 0;
return mode === 'above' ? above : (mode === 'below' ? below : !above && !below);
}
and with a fiddle to prove it: http://jsfiddle.net/t2L274ty/2/
Just an update.
Now if it's a github repository then using just a github shorthand is enough if you do not mind the version of course.
$ bower install desandro/masonry
do like this simply: (as said in comment here is with example with two methods)
import {Component} from 'angular2/core';
@Component({
selector: 'my-app',
template: `
<button (click)="checkEvent($event,'a')" id="abc" class="def">Display Toastr</button>
<button (click)="checkEvent($event,'b')" id="abc1" class="def1">Display Toastr1</button>
`
})
export class AppComponent {
checkEvent(event, id){
console.log(event, id, event.srcElement.attributes.id);
}
}
Another option is to add a new OnClickListener as parameter in setOnClickListener() and overriding the onClick()-method:
mycards_button = ((Button)this.findViewById(R.id.Button_MyCards));
exit_button = ((Button)this.findViewById(R.id.Button_Exit));
// Add onClickListener to mycards_button
mycards_button.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// Start new activity
Intent intent = new Intent(this, MyCards.class);
this.startActivity(intent);
}
});
// Add onClickListener to exit_button
exit_button.setOnClickListener(new OnClickListener() {
public void onClick(View view) {
// Display alertDialog
MyAlertDialog();
}
});
To answer the first question of the three asked, a simple way to see if the .htaccess file is working or not is to trigger a custom error at the top of the .htaccess file:
ErrorDocument 200 "Hello. This is your .htaccess file talking."
RewriteRule ^ - [L,R=200]
On to your second question, if the .htaccess file is not being read it is possible that the server's main Apache configuration has AllowOverride
set to None
. Apache's documentation has troubleshooting tips for that and other cases that may be preventing the .htaccess from taking effect.
Finally, to answer your third question, if you need to debug specific variables you are referencing in your rewrite rule or are using an expression that you want to evaluate independently of the rule you can do the following:
Output the variable you are referencing to make sure it has the value you are expecting:
ErrorDocument 200 "Request: %{THE_REQUEST} Referrer: %{HTTP_REFERER} Host: %{HTTP_HOST}"
RewriteRule ^ - [L,R=200]
Test the expression independently by putting it in an <If>
Directive. This allows you to make sure your expression is written properly or matching when you expect it to:
<If "%{REQUEST_URI} =~ /word$/">
ErrorDocument 200 "Your expression is priceless!"
RewriteRule ^ - [L,R=200]
</If>
Happy .htaccess debugging!
For completeness, here is a java-8 way of doing it
countMap.entrySet().stream().max((entry1, entry2) -> entry1.getValue() > entry2.getValue() ? 1 : -1).get().getKey();
or
Collections.max(countMap.entrySet(), (entry1, entry2) -> entry1.getValue() - entry2.getValue()).getKey();
or
Collections.max(countMap.entrySet(), Comparator.comparingInt(Map.Entry::getValue)).getKey();
I extended this question that is how to gets the row
, column
and value
of all matches value?
here is solution:
import pandas as pd
import numpy as np
def search_coordinate(df_data: pd.DataFrame, search_set: set) -> list:
nda_values = df_data.values
tuple_index = np.where(np.isin(nda_values, [e for e in search_set]))
return [(row, col, nda_values[row][col]) for row, col in zip(tuple_index[0], tuple_index[1])]
if __name__ == '__main__':
test_datas = [['cat', 'dog', ''],
['goldfish', '', 'kitten'],
['Puppy', 'hamster', 'mouse']
]
df_data = pd.DataFrame(test_datas)
print(df_data)
result_list = search_coordinate(df_data, {'dog', 'Puppy'})
print(f"\n\n{'row':<4} {'col':<4} {'name':>10}")
[print(f"{row:<4} {col:<4} {name:>10}") for row, col, name in result_list]
Output:
0 1 2
0 cat dog
1 goldfish kitten
2 Puppy hamster mouse
row col name
0 1 dog
2 0 Puppy
function order_summary_insert()
$OrderLines=$this->input->post('orderlines');
$CustomerName=$this->input->post('customer');
$data = array(
'OrderLines'=>$OrderLines,
'CustomerName'=>$CustomerName
);
$this->db->insert('Customer_Orders',$data);
}
Derek's solution worked fine for me, and I've just simply converted it to PHP, hope it helps somebody out there !
function calcCrow($lat1, $lon1, $lat2, $lon2){
$R = 6371; // km
$dLat = toRad($lat2-$lat1);
$dLon = toRad($lon2-$lon1);
$lat1 = toRad($lat1);
$lat2 = toRad($lat2);
$a = sin($dLat/2) * sin($dLat/2) +sin($dLon/2) * sin($dLon/2) * cos($lat1) * cos($lat2);
$c = 2 * atan2(sqrt($a), sqrt(1-$a));
$d = $R * $c;
return $d;
}
// Converts numeric degrees to radians
function toRad($Value)
{
return $Value * pi() / 180;
}
You can do multicolor outputs without any external programs.
@echo off
SETLOCAL EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
set "DEL=%%a"
)
echo say the name of the colors, don't read
call :ColorText 0a "blue"
call :ColorText 0C "green"
call :ColorText 0b "red"
echo(
call :ColorText 19 "yellow"
call :ColorText 2F "black"
call :ColorText 4e "white"
goto :eof
:ColorText
echo off
<nul set /p ".=%DEL%" > "%~2"
findstr /v /a:%1 /R "^$" "%~2" nul
del "%~2" > nul 2>&1
goto :eof
It uses the color feature of the findstr command.
Findstr can be configured to output line numbers or filenames in a defined color.
So I first create a file with the text as filename, and the content is a single <backspace>
character (ASCII 8).
Then I search all non empty lines in the file and in nul, so the filename will be output in the correct color appended with a colon, but the colon is immediatly removed by the <backspace>
.
EDIT: One year later ... all characters are valid
@echo off
setlocal EnableDelayedExpansion
for /F "tokens=1,2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
set "DEL=%%a"
)
rem Prepare a file "X" with only one dot
<nul > X set /p ".=."
call :color 1a "a"
call :color 1b "b"
call :color 1c "^!<>&| %%%%"*?"
exit /b
:color
set "param=^%~2" !
set "param=!param:"=\"!"
findstr /p /A:%1 "." "!param!\..\X" nul
<nul set /p ".=%DEL%%DEL%%DEL%%DEL%%DEL%%DEL%%DEL%"
exit /b
This uses the rule for valid path/filenames.
If a \..\
is in the path the prefixed elemet will be removed completly and it's not necessary that this element contains only valid filename characters.

For anyone not using storyboards to set the layout constraint. This is a pure programmatic way to get it working on Swift 5:
var discussionsMessageBoxBottomAnchor: NSLayoutConstraint = NSLayoutConstraint()
discussionsMessageBox
. Also, add the listener for keyboard events.For correctly initializing the constraint, you need to first add the subview and then define the constraint.
NotificationCenter.default.addObserver(self,
selector: #selector(self.keyboardNotification(notification:)),
name: NSNotification.Name.UIKeyboardWillChangeFrame,
object: nil)
view.addSubview(discussionsMessageBox)
if #available(iOS 11.0, *) {
discussionsMessageBoxBottomAnchor = discussionsMessageBox.bottomAnchor.constraint(equalTo: view.safeAreaLayoutGuide.bottomAnchor, constant: 0)
} else {
// Fallback on earlier versions
discussionsMessageBoxBottomAnchor = discussionsMessageBox.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: 0)
}
NSLayoutConstraint.activate([ discussionsMessageBoxBottomAnchor ])
deinit
.deinit {
NotificationCenter.default.removeObserver(self)
}
extension DiscussionsViewController {
@objc func keyboardNotification(notification: NSNotification) {
guard let userInfo = notification.userInfo else { return }
let endFrame = (userInfo[UIKeyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue
let endFrameY = endFrame?.origin.y ?? 0
let duration:TimeInterval = (userInfo[UIKeyboardAnimationDurationUserInfoKey] as? NSNumber)?.doubleValue ?? 0
let animationCurveRawNSN = userInfo[UIKeyboardAnimationCurveUserInfoKey] as? NSNumber
let animationCurveRaw = animationCurveRawNSN?.uintValue ?? UIView.AnimationOptions.curveEaseInOut.rawValue
let animationCurve:UIView.AnimationOptions = UIView.AnimationOptions(rawValue: animationCurveRaw)
if endFrameY >= UIScreen.main.bounds.size.height {
self.discussionsMessageBoxBottomAnchor.constant = 0.0
} else {
//Changed line
self.discussionsMessageBoxBottomAnchor.constant = -1 * (endFrame?.size.height ?? 0.0)
}

There are a number of Atom packages which give you access to the terminal from within Atom. Try a few out to find the best option for you.
Some recommendations which work in Ubuntu (with their primary keyboard shortcuts):
Edit: recommended plugin changed as terminal-plus
is no longer maintained. Thanks for the head's-up, @MorganRodgers.
If you want to open a terminal panel in Atom, try atom-ide-terminal
. Use the keyboard shortcut ctrl-`
to open a new terminal instance.
If you just want a shortcut to open your external terminal from within Atom, try atom-terminal
(this is what I use). You can use ctrl-shift-t
to open your external terminal in the current file's directory, or alt-shift-t
to open the terminal in the project's root directory.
Will delete all files/directories below the current one.
find -mindepth 1 -delete
If you want to do the same with another directory whose name you have, you can just name that
find <name-of-directory> -mindepth 1 -delete
If you want to remove not only the sub-directories and files of it, but also the directory itself, omit -mindepth 1
. Do it without the -delete
to get a list of the things that will be removed.
It would be more useful to have a full function for real-world usage of truncating a decimal in C#. This could be converted to a Decimal extension method pretty easy if you wanted:
public decimal TruncateDecimal(decimal value, int precision)
{
decimal step = (decimal)Math.Pow(10, precision);
decimal tmp = Math.Truncate(step * value);
return tmp / step;
}
If you need VB.NET try this:
Function TruncateDecimal(value As Decimal, precision As Integer) As Decimal
Dim stepper As Decimal = Math.Pow(10, precision)
Dim tmp As Decimal = Math.Truncate(stepper * value)
Return tmp / stepper
End Function
Then use it like so:
decimal result = TruncateDecimal(0.275, 2);
or
Dim result As Decimal = TruncateDecimal(0.275, 2)
You can use the clearfix
to do "layout preserving" the same way overflow: hidden
does.
.clearfix:before,
.clearfix:after {
content: ".";
display: block;
height: 0;
overflow: hidden;
}
.clearfix:after { clear: both; }
.clearfix { zoom: 1; } /* IE < 8 */
add class="clearfix"
class to the parent, and remove overflow: hidden;
Short answer:
$ ssh-keygen -p
This will then prompt you to enter the keyfile location, the old passphrase, and the new passphrase (which can be left blank to have no passphrase).
If you would like to do it all on one line without prompts do:
$ ssh-keygen -p [-P old_passphrase] [-N new_passphrase] [-f keyfile]
Important: Beware that when executing commands they will typically be logged in your ~/.bash_history
file (or similar) in plain text including all arguments provided (i.e. the passphrases in this case). It is, therefore, is recommended that you use the first option unless you have a specific reason to do otherwise.
Notice though that you can still use -f keyfile
without having to specify -P
nor -N
, and that the keyfile defaults to ~/.ssh/id_rsa
, so in many cases, it's not even needed.
You might want to consider using ssh-agent, which can cache the passphrase for a time. The latest versions of gpg-agent also support the protocol that is used by ssh-agent.
import webbrowser
webbrowser.open(url, new=0, autoraise=True)
Display url using the default browser. If new is 0, the url is opened in the same browser window if possible. If new is 1, a new browser window is opened if possible. If new is 2, a new browser page (“tab”) is opened if possible. If autoraise is True, the window is raised
webbrowser.open_new(url)
Open url in a new window of the default browser
webbrowser.open_new_tab(url)
Open url in a new page (“tab”) of the default browser

Hope this help someone.

To print the N first characters you can remove the N+1 characters up to the end of line:
$ sed 's/.//5g' <<< "defn-test"
defn
top5 = array[:5]
array[start:stop:step]
array[start:]
, array[:stop]
, array[::step]
import itertools
top5 = itertools.islice(my_list, 5) # grab the first five elements
You can't slice a generator directly in Python. itertools.islice()
will wrap an object in a new slicing generator using the syntax itertools.islice(generator, start, stop, step)
Remember, slicing a generator will exhaust it partially. If you want to keep the entire generator intact, perhaps turn it into a tuple or list first, like: result = tuple(generator)
They say it right there in the documentation for the FPDF constructor:
FPDF([string orientation [, string unit [, mixed size]]])
This is the class constructor. It allows to set up the page size, the orientation and the unit of measure used in all methods (except for font sizes). Parameters ...
size
The size used for pages. It can be either one of the following values (case insensitive):
A3 A4 A5 Letter Legal
or an array containing the width and the height (expressed in the unit given by unit).
They even give an example with custom size:
Example with a custom 100x150 mm page size:
$pdf = new FPDF('P','mm',array(100,150));
Here is a script I used for recursive trimming. Replace $1 with the directory you want, of course.

using nodejs without express/external libraries I made use of the below method within my server.js file. The key parts here are getting the origin from the request header then allowing it in the server response at which point we can set the header that will be returned including the allowed origin if a match is found.
**const origin = req.headers.origin;**
let decoder = new StringDecoder('utf-8');
let buffer = '';
req.on('data', function (data) {
buffer += decoder.write(data);
});
req.on('end', function () {
buffer += decoder.end();
let chosenHandler = typeof (server.router[trimmedPath]) !== 'undefined' ? server.router[trimmedPath] : handlers.notFound;
const data = { ....data object vars}
// should be wrapped in try catch block
chosenHandler(data, function (statusCode, payload, contentType) {
server.processHandlerResponse(res, method, trimmedPath, statusCode, payload, contentType, **origin**);
server.processHandlerResponse = function (res, method, trimmedPath, statusCode, payload, contentType, origin) {
contentType = typeof (contentType) == 'string' ? contentType : 'json';
statusCode = typeof (statusCode) == 'number' ? statusCode : 200;
let payloadString = '';
if (contentType == 'json') {
res.setHeader('Content-Type', 'application/json');
const allowedOrigins = ['https://www.domain1.com', 'https://someotherdomain','https://yetanotherdomain',
...// as many as you need
];
**if (allowedOrigins.indexOf(origin) > -1) {
res.setHeader('Access-Control-Allow-Origin', origin);
}**
payload = typeof (payload) == 'object' ? payload : {};
payloadString = JSON.stringify(payload);
}
... // if (other content type) ...rinse and repeat..
As the others have said, there is no error tracking for send mail it return the boolean result of adding the mail to the outgoing queue. If you want to track true success failure try using SMTP with a mail library like Swift Mailer, Zend_Mail, or phpmailer.
At some point, I suppose you will add your programatically created LinearLayout to some root layout that you defined in .xml. This is just a suggestion of mine and probably one of many solutions, but it works: Simply set an ID for the programatically created layout, and add it to the root layout that you defined in .xml, and then use the set ID to add the Fragment.
It could look like this:
LinearLayout rowLayout = new LinearLayout();
rowLayout.setId(whateveryouwantasid);
// add rowLayout to the root layout somewhere here
FragmentManager fragMan = getFragmentManager();
FragmentTransaction fragTransaction = fragMan.beginTransaction();
Fragment myFrag = new ImageFragment();
fragTransaction.add(rowLayout.getId(), myFrag , "fragment" + fragCount);
fragTransaction.commit();
Simply choose whatever Integer value you want for the ID:
rowLayout.setId(12345);
If you are using the above line of code not just once, it would probably be smart to figure out a way to create unique-IDs, in order to avoid duplicates.
UPDATE:
Here is the full code of how it should be done: (this code is tested and works) I am adding two Fragments to a LinearLayout with horizontal orientation, resulting in the Fragments being aligned next to each other. Please also be aware, that I used a fixed height and width of 200dp, so that one Fragment does not use the full screen as it would with "match_parent".
MainActivity.java:
public class MainActivity extends Activity {
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout fragContainer = (LinearLayout) findViewById(R.id.llFragmentContainer);
LinearLayout ll = new LinearLayout(this);
ll.setOrientation(LinearLayout.HORIZONTAL);
ll.setId(12345);
getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 1"), "someTag1").commit();
getFragmentManager().beginTransaction().add(ll.getId(), TestFragment.newInstance("I am frag 2"), "someTag2").commit();
fragContainer.addView(ll);
}
}
TestFragment.java:
public class TestFragment extends Fragment {
public static TestFragment newInstance(String text) {
TestFragment f = new TestFragment();
Bundle b = new Bundle();
b.putString("text", text);
f.setArguments(b);
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment, container, false);
((TextView) v.findViewById(R.id.tvFragText)).setText(getArguments().getString("text"));
return v;
}
}

And this is the result of the above code: (the two Fragments are aligned next to each other)
mysqli_select_db()
should have 2 parameters, the connection link and the database name -
mysqli_select_db($con, 'phpcadet') or die(mysqli_error($con));
Using mysqli_error
in the die statement will tell you exactly what is wrong as opposed to a generic error message.
If you have luasocket installed:
local socket = require 'socket'

The Connector 6.7.x does not integrate the native data provider anymore. For "Visual Studio 2012" or less, you have to install "MySQL for Visual Studio". If you are using "Visual Studio 2013" there is no possibility to integrate MySQL for the "Entity Framework" yet. A solution should be available on 10/2013!
It is a whole lot easier if you think of unicode as a character set (which it actually is - it is very basically the numbered set of all known characters). You can encode it as UTF-8 (1-3 bytes per character depending) or maybe UTF-16 (2 bytes per character or 4 bytes using surrogate pairs).
Back in the mist of time Java used to use UCS-2 to encode the unicode character set. This could only handle 2 bytes per character and is now obsolete. It was a fairly obvious hack to add surrogate pairs and move up to UTF-16.
A lot of people think they should have used UTF-8 in the first place. When Java was originally written unicode had far more than 65535 characters anyway...

(slow but pure git solution) and BFG (easier and very performant), there is also another tool to filter with good performance:
https://github.com/xoofx/git-rocket-filter
From its description:
The purpose of git-rocket-filter is similar to the command git-filter-branch
while providing the following unique features:
I am not sure it will help but you can try this.This worked for me
Start -> Visual Studio Installer -> Repair
after this enable the Microsoft Symbols Server under
TOOLS->Options->Debugging->Symbols
This will automatically set all the issues.

so I have a solution that isn't perfect but it worked for me. Use the polygon example from Google, and use the pinpoint on Google Maps to get lat & long locations.
I used what I call "ocular copy & paste" where you look at the screen and then write in the numbers you want ;-)

mapTypeId: 'terrain'
});
// Define the LatLng coordinates for the polygon's path.
var triangleCoords = [

Try this PDF Duo .Net converting component for converting HTML to PDF from ASP.NET application without using additional dlls.
You can pass the HTML string or file, or stream to generate the PDF. Use the code below (Example C#):
string file_html = @"K:\hdoc.html";
string file_pdf = @"K:\new.pdf";
try
{
DuoDimension.HtmlToPdf conv = new DuoDimension.HtmlToPdf();
conv.OpenHTML(file_html);
conv.SavePDF(file_pdf);
textBox4.Text = "C# Example: Converting succeeded";
}
Info + C#/VB examples you can find at: http://www.duodimension.com/html_pdf_asp.net/component_html_pdf.aspx
You can add style to your text:
style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);
text-shadow: rgb(255, 255, 255) -2px -2px 0px, rgb(255, 255, 255) -2px 2px 0px,
rgb(255, 255, 255) 2px -2px 0px, rgb(255, 255, 255) 2px 2px 0px;"
White, in this example. Does not work in IE :)
I suggest to use id command as it tests valid user existence wrt passwd file entry which is not necessary means the same:
if [ `id -u $USER_TO_CHECK 2>/dev/null || echo -1` -ge 0 ]; then
echo FOUND
fi
Note: 0 is root uid.
If you want to be real smart, at the command line type:
echo svcutil.exe /language:cs /out:generatedProxy.cs /config:app.config http://localhost:8000/ServiceModelSamples/service >CreateService.cmd
Then you have CreateService.cmd
that you can run whenever you want (.cmd
is just another extension for .bat
files)
You could write a directive for this, which simply assigns the (jqLite) element to the scope using an attribute-given name.
Here is the directive:
app.directive("ngScopeElement", function () {
var directiveDefinitionObject = {
restrict: "A",
compile: function compile(tElement, tAttrs, transclude) {
return {
pre: function preLink(scope, iElement, iAttrs, controller) {
scope[iAttrs.ngScopeElement] = iElement;
}
};
}
};
return directiveDefinitionObject;
});
Usage:
app.directive("myDirective", function() {
return {
template: '<div><ul ng-scope-element="list"><li ng-repeat="item in items"></ul></div>',
link: function(scope, element, attrs) {
scope.list[0] // scope.list is the jqlite element,
// scope.list[0] is the native dom element
}
}
});
Some remarks:
scope.list
from myDirective
s postLink-Function, which you are very likely using anywayngScopeElement
uses a preLink-function, so that directives nested within the element having ng-scope-element
can already access scope.list
Think of (char *) as string.begin(). The essential difference is that (char *) is an iterator and std::string is a container. If you stick to basic strings a (char *) will give you what std::string::iterator does. You could use (char *) when you want the benefit of an iterator and also compatibility with C, but that's the exception and not the rule. As always, be careful of iterator invalidation. When people say (char *) isn't safe this is what they mean. It's as safe as any other C++ iterator.
You can use \
to indicate that any line of Ruby continues on the next line. This works with strings too:
string = "this is a \
string that spans lines"
puts string.inspect
will output "this is a string that spans lines"
Including its "big result", this paper describes a couple of variants of in-place merge sort (PDF):

In-place sorting with fewer moves
Jyrki Katajainen, Tomi A. Pasanen
It is shown that an array of n elements can be sorted using O(1) extra space, O(n log n / log log n) element moves, and n log2n + O(n log log n) comparisons. This is the first in-place sorting algorithm requiring o(n log n) moves in the worst case while guaranteeing O(n log n) comparisons, but due to the constant factors involved the algorithm is predominantly of theoretical interest.
I think this is relevant too. I have a printout of it lying around, passed on to me by a colleague, but I haven't read it. It seems to cover basic theory, but I'm not familiar enough with the topic to judge how comprehensively:
http://comjnl.oxfordjournals.org/cgi/content/abstract/38/8/681
Optimal Stable Merging
Antonios Symvonis
This paper shows how to stably merge two sequences A and B of sizes m and n, m = n, respectively, with O(m+n) assignments, O(mlog(n/m+1)) comparisons and using only a constant amount of additional space. This result matches all known lower bounds...
If you don't remove manually these fragments, they are still attached to the activity. Your activity is not destroyed so these fragments are too. To remove (so destroy) these fragments, you can call:
fragmentTransaction.remove(yourfragment).commit()
Hope it helps to you
a = dict(one=1, two=2, three=3)
Providing keyword arguments as in this example only works for keys that are valid Python identifiers. Otherwise, any valid keys can be used.
It's method syntax (which I find easier to read) but this might do it
Updated post comment
Use .FirstOrDefault()
instead of .First()
With regard to the dates average, you may have to drop that ordering for the moment as I am unable to get to an IDE at the moment
var groupByReference = context.Measurements
.GroupBy(m => m.Reference)
.Select(g => new {Creation = g.FirstOrDefault().CreationTime,
// Avg = g.Average(m => m.CreationTime.Ticks),
Items = g })
.OrderBy(x => x.Creation)
// .ThenBy(x => x.Avg)
.Take(numOfEntries)
.ToList();
A bit old, but I was still getting the same SettingWithCopyWarning. Here was my solution:

What kind of document library information do you want in the view? How do you want the user to filter the view?
In general the most powerful way of creating views in sharepoint is with the data view web part. http://office.microsoft.com/en-us/sharepointdesigner/HA100948041033.aspx
You will need Microsoft Office SharePoint Designer.
You can present different views of you folders using the data view filter and sorting controls.
You can use web part connections to filter a dataview. You can use any datasource linked to say a drop down to filter a dataview. How to tie a dropdown list to a gridview in Sharepoint 2007?
If you need not equal object condition use cross join sequences:
var query = from obj1 in set1
from obj2 in set2
where obj1.key1 == obj2.key2 && obj1.key3.contains(obj2.key5) [...conditions...]
You can pass params directly to $http.get()
The following works fine
$http.get(user.details_path, {
params: { user_id: user.id }
});
Follow the below steps it will helps you.
step 1: Go to to your site root folder and you can find the .htaccess
file there. Open it with a text editor and find the line #RewriteBase /magento/
. Just replace it with #RewriteBase /
take out just the 'magento/'
step 2: Then go to your admin panel and enable the Rewrites(set yes for Use Web Server Rewrites). You can find it at System->Configuration->Web->Search Engine Optimization.
step 3: Then go to Cache management page (system cache management ) and refresh your cache and refresh to check the site.
I had the similar problem. It was a maven project with the following snippet of pom.xml.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<release>9</release>
</configuration>
</plugin>
</plugins>
</build>
I had to change the following.
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<release>11</release>
</configuration>
</plugin>
</plugins>
</build>
If you have already installed JDK 11 and working with java 9 or java 10 as maven compiler, eclipse can not detect. Hence change the release to 11 or the actual installed version of JDK.
The EF Core doesn't create DBset for the SQL views automatically in the context calss, we can add them manually as below.
public partial class LocalDBContext : DbContext
{
public LocalDBContext(DbContextOptions<LocalDBContext> options) : base(options)
{
}
public virtual DbSet<YourView> YourView { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity<YourView>(entity => {
entity.HasKey(e => e.ID);
entity.ToTable("YourView");
entity.Property(e => e.Name).HasMaxLength(50);
});
}
}
The sample view is defined as below with few properties
using System;
using System.Collections.Generic;
namespace Project.Entities
{
public partial class YourView
{
public string Name { get; set; }
public int ID { get; set; }
}
}
After adding a class for the view and DB set in the context class, you are good to use the view object through your context object in the controller.
A compiler consists of two major blocks: the 'front end' and the 'back end'. The front end of a compiler analyzes the source code and builds some form of a 'intermediary representation' of said source code which is much easier to analyze by a machine algorithm than is the source code (i.e. whereas the source code e.g. C++ is designed to help the human programmer to write code, the intermediary form is designed to help simplify the algorithm that analyzes said intermediary form easier). The back end of a compiler takes the intermediary form and then converts it to a 'target language'.
Now, the target language for general-use compilers are assembler languages for various processors, but there's nothing to prohibit a compiler back end to produce code in some other language, for as long as said target language is (at least) as flexible as a general CPU assembler.
Now, as you can probably imagine, C is definitely as flexible as a CPU's assembler, such that a C++ to C compiler is really no problem to implement from a technical pov.
So you have: C++ ---frontEnd---> someIntermediaryForm ---backEnd---> C
You may want to check these guys out: http://www.edg.com/index.php?location=c_frontend (the above link is just informative for what can be done, they license their front ends for tens of thousands of dollars)
PS As far as i know, there is no such a C++ to C compiler by GNU, and this totally beats me (if i'm right about this). Because the C language is fairly small and it's internal mechanisms are fairly rudimentary, a C compiler requires something like one man-year work (i can tell you this first hand cause i wrote such a compiler myself may years ago, and it produces a [virtual] stack machine intermediary code), and being able to have a maintained, up-to-date C++ compiler while only having to write a C compiler once would be a great thing to have...
There are two interfaces
org.springframework.web.context.request.WebRequest
org.springframework.web.context.request.NativeWebRequest
Allows for generic request parameter access as well as request/session
attribute access, without ties to the native Servlet/Portlet API.
Ex.:
@RequestMapping(value = "/", method = GET)
public List<T> getAll(WebRequest webRequest){
Map<String, String[]> params = webRequest.getParameterMap();
//...
}
P.S. There are Docs about arguments which can be used as Controller params.
I know this is an ancient question, but I just thought that I'd weigh in.
I'm using disableScroll. Simple and it works like in a dream.
I have had some trouble disabling scroll on body, but allowing it on child elements (like a modal or a sidebar). It looks like that something can be done using disableScroll.on([element], [options]);
, but I haven't gotten that to work just yet.
The reason that this is prefered compared to overflow: hidden;
on body is that the overflow-hidden can get nasty, since some things might add overflow: hidden;
like this:
... This is good for preloaders and such, since that is rendered before the CSS is finished loading.
But it gives problems, when an open navigation should add a class to the body
-tag (like <body class="body__nav-open">
). And then it turns into one big tug-of-war with overflow: hidden; !important
and all kinds of crap.
Currently (Swift 2.1) you can check it using 3 ways:
Using '?' answered by @Sulthan
And using as?
operator:
if let delegateMe = self.delegate as? YourCustomViewController
{
delegateMe.onSuccess()
}
Basically it depends on what you are trying to achieve:
Look, the sed script that prints the 100 last lines you can find in the documentation for sed (https://www.gnu.org/software/sed/manual/sed.html#tail):
$ cat sed.cmd
1! {; H; g; }
1,100 !s/[^\n]*\n//
$p
$ sed -nf sed.cmd logfilename
For me it is way more difficult than your script so
tail -n 100 logfilename
is much much simpler. And it is quite efficient, it will not read all file if it is not necessary. See my answer with strace report for tail ./huge-file
: https://unix.stackexchange.com/questions/102905/does-tail-read-the-whole-file/102910#102910
I like to think of branches as where you're going, tags as where you've been.
A tag feels like a bookmark of a particular important point in the past, such as a version release.
Whereas a branch is a particular path the project is going down, and thus the branch marker advances with you. When you're done you merge/delete the branch (i.e. the marker). Of course, at that point you could choose to tag that commit.
There are two ways to do this:
CSS: Use width as %, like 75%, so the width of the div will change automatically when user resizes the browser.
Javascipt: Use resize event
$(window).bind('resize', function()
{
if($(window).width() > 500)
$('#divID').css('width', '300px');
else
$('divID').css('width', '200px');
});
Hope this will help you :)
For completeness and correct resource management:
ICursor cursor = null;
try
{
cursor = db.RawQuery("SELECT * FROM " + RECORDS_TABLE + " WHERE " + RECORD_ID + "=?", new String[] { id + "" });
if (cursor.Count > 0)
{
cursor.MoveToFirst();
}
return GetRecordFromCursor(cursor); // Copy cursor props to custom obj
}
finally // IMPORTANT !!! Ensure cursor is not left hanging around ...
{
if(cursor != null)
cursor.Close();
}
mysqli_fetch_array()
returns NULL
if there is no row.
In procedural style:
if ( ! $row = mysqli_fetch_array( $result ) ) {
... no result ...
}
else {
... get the first result in $row ...
}
In Object oriented style:
if ( ! $row = $result->fetch_array() ) {
...
}
else {
... get the first result in $row ...
}
I've implemented and tested this one; it should cover most bases:
public static <T> List<T> safeSubList(List<T> list, int fromIndex, int toIndex) {
int size = list.size();
if (fromIndex >= size || toIndex <= 0 || fromIndex >= toIndex) {
return Collections.emptyList();
}
fromIndex = Math.max(0, fromIndex);
toIndex = Math.min(size, toIndex);
return list.subList(fromIndex, toIndex);
}
This works fine if you want the http protocol also since it could be http or https.
$domainURL = $_SERVER['REQUEST_SCHEME']."://".$_SERVER['SERVER_NAME'];
I can offer two options
Based on your description I'm guessing you are doing something like
Set wb2 = Application.Workbooks.Open("YourFile.xls")
wb2.Sheets("YourSheet").[<YourRange>].Copy
ThisWorkbook.Sheets("SomeSheet").Paste
wb2.close
If this is the case, you don't need to copy via the clipboard. This method copies from source to destination directly. No data in clipboard = no prompt
Set wb2 = Application.Workbooks.Open("YourFile.xls")
wb2.Sheets("YourSheet").[<YourRange>].Copy ThisWorkbook.Sheets("SomeSheet").Cells(<YourCell")
wb2.close
You can prevent all alert pop-ups by setting
Application.DisplayAlerts = False
[Edit]
Dim rSrc As Range
Dim rDst As Range
Set rSrc = wb2.Sheets("YourSheet").Range("YourRange")
Set rDst = ThisWorkbook.Sheets("SomeSheet").Cells("YourCell").Resize(rSrc.Rows.Count, rSrc.Columns.Count)
rDst = rSrc.Value
This may help someone,

You don't need three .yml files for this. You can have a single application.yml file and write profile specific properties in the same where each profile section is separated by 3 hyphen (---)
Next, for selecting the current active profile, you can specify that as well in your application.yml file, like this :
spring:
profiles:
active:
- local
However, this configuration will be overriden if you set an Environment variable, eg : SPRING_PROFILES_ACTIVE = dev
Here is a sample file for you requirement:
# include common properties for every profile in this section
server.port: 5000
spring:
profiles:
active:
- local
---
# profile specific properties
spring:
profiles: local
datasource:
url: jdbc:mysql://localhost:3306/
username: root
password: root
---
# profile specific properties
spring:
profiles: dev
datasource:
url: jdbc:mysql://<dev db url>
username: <username>
password: <password>
Since PowerShell doesn't support "-Credential" usage via many of the cmdlets (very annoying), and mapping a network drive via WMI proved to be very unreliable in PS, I found pre-caching the user credentials via a net use command to work quite well:
# cache credentials for our network path
net use \\server\C$ $password /USER:$username
Any operation that uses \\server\C$ in the path seems to work using the *-item cmdlets.
You can also delete the share when you're done:
net use \\server\C$ /delete
The main reason ++ comes in handy in C-like languages is for keeping track of indices. In Python, you deal with data in an abstract way and seldom increment through indices and such. The closest-in-spirit thing to ++
is the next
method of iterators.
After OP's edit:
def contains(small, big):
for i in xrange(1 + len(big) - len(small)):
if small == big[i:i+len(small)]:
return i, i + len(small) - 1
return False
You can do this:
var getValue = function (input, defaultValue) {
return input.value || defaultValue;
};
Something even simpler and more basic in case you're happy for your string to contain any printable characters:
#include <time.h> // we'll use time for the seed
#include <string.h> // this is for strcpy
void randomString(int size, char* output) // pass the destination size and the destination itself
{
srand(time(NULL)); // seed with time
char src[size];
size = rand() % size; // this randomises the size (optional)
src[size] = '\0'; // start with the end of the string...
// ...and work your way backwards
while(--size > -1)
src[size] = (rand() % 94) + 32; // generate a string ranging from the space character to ~ (tilde)
strcpy(output, src); // store the random string
}
try this package, works wonders, and was made for date/time...

Illustration of @Jan Philip Matuschek excellent explanation.(Please up-vote his answer, not this; I am adding this as I took a little time in understanding the original answer)
The bounding box technique of optimizing of finding nearest neighbors would need to derive the minimum and maximum latitude,longitude pairs, for a point P at distance d . All points that fall outside these are definitely at a distance greater than d from the point. One thing to note here is the calculation of latitude of intersection as is highlighted in Jan Philip Matuschek explanation. The latitude of intersection is not at the latitude of point P but slightly offset from it. This is a often missed but important part in determining the correct minimum and maximum bounding longitude for point P for the distance d.This is also useful in verification.
The haversine distance between (latitude of intersection,longitude high) to (latitude,longitude) of P is equal to distance d.

30x30 is points, which means 30px @1x, 60px @2x, not somewhere in-between. Also, it's not a great idea to embed the title of the tab into the image—you're going to have pretty poor accessibility and localization results like that.
Simple:
btn.setBackground(Color.red);
To use RGB values:
btn[i].setBackground(Color.RGBtoHSB(int, int, int, float[]));
This will work.

You need to set the flags after the project
command in your CMakeLists.txt.
Also, if you're calling include(${QT_USE_FILE})
or add_definitions(${QT_DEFINITIONS})
, you should include these set
commands after the Qt ones since these would append further flags. If that is the case, you maybe just want to append your flags to the Qt ones, so change to e.g.
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -O0 -ggdb")
As an alternative and superior solution, you could use a custom counter in a before element. It involves no extra HTML markup. A CSS reset should be used alongside it, or at least styling removed from the ol
element (list-style-type: none, reset margin
), otherwise the element will have two counters.
<ol>
<li>First line</li>
<li>Second line</li>
</ol>
CSS:
ol {
counter-reset: my-badass-counter;

You should add the pipe to the interpolation

There's also the DateTime class which implements a function for comparison operators.
// $now = new DateTime();
$dtA = new DateTime('05/14/2010 3:00PM');
$dtB = new DateTime('05/14/2010 4:00PM');
if ( $dtA > $dtB ) {
echo 'dtA > dtB';
}
else {
echo 'dtA <= dtB';
}
If you want to only trigger validation when the input looses focus you can use onBlur
Trivia: React <17 listens to blur
event and >=17 listens to focusout
event.
ROUND(time_to_sec((TIMEDIFF(NOW(), "2015-06-10 20:15:00"))) / 60);
You can use:
To Insert After,
jQuery("#source").insertAfter("#destination");
To Insert inside another element,
jQuery("#source").appendTo("#destination");
What Chad says, except its better to use .keyup in this case because with .keydown and .keypress the value of the input is still the older value i.e. the newest key pressed would not be reflected if .val() is called.
This should probably be a comment on Chad's answer but I dont have privileges to comment yet.
Use the change event.
$('#myform :checkbox').change(function() {
// this represents the checkbox that was checked
// do something with it
});
You can try a list comp
>>> exampleSet = [{'type':'type1'},{'type':'type2'},{'type':'type2'}, {'type':'type3'}]
>>> keyValList = ['type2','type3']
>>> expectedResult = [d for d in exampleSet if d['type'] in keyValList]
>>> expectedResult
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]
Another way is by using filter
>>> list(filter(lambda d: d['type'] in keyValList, exampleSet))
[{'type': 'type2'}, {'type': 'type2'}, {'type': 'type3'}]
Would like to outline a brief semantic parallel to an already correct answer.
In 'simple' terms, a recursive CTE can be semantically defined as the following parts:
1: The CTE query. Also known as ANCHOR.
2: The recursive CTE query on the CTE in (1) with UNION ALL (or UNION or EXCEPT or INTERSECT) so the ultimate result is accordingly returned.
3: The corner/termination condition. Which is by default when there are no more rows/tuples returned by the recursive query.
A short example that will make the picture clear:
;WITH SupplierChain_CTE(supplier_id, supplier_name, supplies_to, level)
AS
(
SELECT S.supplier_id, S.supplier_name, S.supplies_to, 0 as level
FROM Supplier S
WHERE supplies_to = -1 -- Return the roots where a supplier supplies to no other supplier directly
UNION ALL
-- The recursive CTE query on the SupplierChain_CTE
SELECT S.supplier_id, S.supplier_name, S.supplies_to, level + 1
FROM Supplier S
INNER JOIN SupplierChain_CTE SC
ON S.supplies_to = SC.supplier_id
)
-- Use the CTE to get all suppliers in a supply chain with levels
SELECT * FROM SupplierChain_CTE
Explanation: The first CTE query returns the base suppliers (like leaves) who do not supply to any other supplier directly (-1)
The recursive query in the first iteration gets all the suppliers who supply to the suppliers returned by the ANCHOR. This process continues till the condition returns tuples.
UNION ALL returns all the tuples over the total recursive calls.
Another good example can be found here.
PS: For a recursive CTE to work, the relations must have a hierarchical (recursive) condition to work on. Ex: elementId = elementParentId.. you get the point.
When testing for directories remember that every directory contains two special files.
One is called '.' and the other '..'
. is the directory's own name while .. is the name of it's parent directory.
To avoid trailing backslash problems just test to see if the directory knows it's own name.
eg:
if not exist %temp%\buffer\. mkdir %temp%\buffer
The row_number() function would be the best approach to this problem.
UPDATE T
SET T.Number = R.rowNum
FROM Test T
JOIN (
SELECT T2.id,row_number() over (order by T2.Id desc) rowNum from Test T2
) R on T.id=R.id

mentioned in other answers, you can use css()

The following captures stdout and stderr of the process in a single variable. It is Python 2 and 3 compatible:
from subprocess import check_output, CalledProcessError, STDOUT
command = ["ls", "-l"]
try:
output = check_output(command, stderr=STDOUT).decode()
success = True
except CalledProcessError as e:
output = e.output.decode()
success = False
If your command is a string rather than an array, prefix this with:
import shlex
command = shlex.split(command)
I have slightly modified the accepted answer by handling value types. I came across this when trying to do the following and because GetProperties() is zero length for value types I was getting an empty dataset. I know this is not the use case for the OP but thought I'd post this change in case anyone else came across the same thing.
Enumerable.Range(1, 10).ToList().ToDataSet();
public static DataSet ToDataSet<T>(this IList<T> list)
{
var elementType = typeof(T);
var ds = new DataSet();
var t = new DataTable();
ds.Tables.Add(t);
if (elementType.IsValueType)
{
var colType = Nullable.GetUnderlyingType(elementType) ?? elementType;
t.Columns.Add(elementType.Name, colType);
} else
{
//add a column to table for each public property on T
foreach (var propInfo in elementType.GetProperties())
{
var colType = Nullable.GetUnderlyingType(propInfo.PropertyType) ?? propInfo.PropertyType;
t.Columns.Add(propInfo.Name, colType);
}
}
//go through each property on T and add each value to the table
foreach (var item in list)
{
var row = t.NewRow();
if (elementType.IsValueType)
{
row[elementType.Name] = item;
}
else
{
foreach (var propInfo in elementType.GetProperties())
{
row[propInfo.Name] = propInfo.GetValue(item, null) ?? DBNull.Value;
}
}
t.Rows.Add(row);
}
return ds;

Following are the rules defining the valid combinations in each number of an IP address:
Any three-digit number beginning with 1
.
Any three-digit number beginning with 2
if the second digit is 0
through 4
.
25
if the third digit is 0
through 5
.Let'start with (((25[0-5])|(2[0-4]\d)|(1\d{2})|(\d{1,2}))\.)
, a set of four nested subexpressions, and we’ll look at them in reverse order. (\d{1,2})
matches any one- or two-digit number or numbers 0
through 99
. (1\d{2})
matches any three-digit number starting with 1
(1
followed by any two digits), or numbers 100
through 199
. (2[0-4]\d)
matches numbers 200
through 249
. (25[0-5])
matches numbers 250
through 255
. Each of these subexpressions is enclosed within another subexpression with an |
between each (so that one of the four subexpressions has to match, not all). After the range of numbers comes \.
to match .
, and then the entire series (all the number options plus \.
) is enclosed into yet another subexpression and repeated three times using {3}
. Finally, the range of numbers is repeated (this time without the trailing \.
) to match the final IP address number. By restricting each of the four numbers to values between 0
and 255
, this pattern can indeed match valid IP addresses and reject invalid addresses.
Excerpt From: Ben Forta. “Learning Regular Expressions.”
If neither a character is wanted at the beginning of IP address nor at the end, ^
and $
metacharacters ought to be used, respectively.

I have faced similar problem and it was returning #N/A
. That means matching data is present but you might having extra space in the M3 column record, that may prevent it from getting exact value. Because you have set last parameter as FALSE, it is looking for "exact match".
This formula is correct: =VLOOKUP(M3,Sheet1!$A$2:$Q$47,13,FALSE)
Based on comments below, it no longer works in modern browsers
This question demonstrates an approach that might be helpful to you: Silent print an embedded PDF
It uses the <embed>
tag to embed the PDF in the document:
<embed
type="application/pdf"
src="path_to_pdf_document.pdf"
id="pdfDocument"
width="100%"
height="100%" />
Then you call the .print()
method on the element in Javascript when the PDF is loaded:
function printDocument(documentId) {
var doc = document.getElementById(documentId);
//Wait until PDF is ready to print
if (typeof doc.print === 'undefined') {
setTimeout(function(){printDocument(documentId);}, 1000);
} else {
doc.print();
}
}
You could place the embed in a hidden iframe and print it from there, giving you a seamless experience.
From the MSDN website:
This error frequently occurs if you declare a variable in a loop or a try or if block and then attempt to access it from an enclosing code block or a separate code block.
So declare the variable outside the block.
Two possibilities. Either use a combined key:
class MyKey {
int firstIndex;
int secondIndex;
// important: override hashCode() and equals()
}
Or a Map of Map:
Map<Integer, Map<Integer, Integer>> myMap;
Do not use Jo Liss's resumer answer. It will work in most cases, but in my case it lost me a good 4 or 5 hours bug finding. There is no need for third party modules to do this.
NEW ANSWER:
var Readable = require('stream').Readable
var s = new Readable()
s.push('beep') // the string you want
s.push(null) // indicates end-of-file basically - the end of the stream
This should be a fully compliant Readable stream. See here for more info on how to use streams properly.
OLD ANSWER: Just use the native PassThrough stream:
var stream = require("stream")
var a = new stream.PassThrough()
a.write("your string")
a.end()
a.pipe(process.stdout) // piping will work as normal
/*stream.on('data', function(x) {
// using the 'data' event works too
console.log('data '+x)
})*/
/*setTimeout(function() {
// you can even pipe after the scheduler has had time to do other things
a.pipe(process.stdout)
},100)*/
a.on('end', function() {
console.log('ended') // the end event will be called properly
})
Note that the 'close' event is not emitted (which is not required by the stream interfaces).
You can use .add() and .subtract() method to get yesterday and tomorrow date. Then use format method to get only date .format("D/M/Y"), D stand for Day, M for Month, Y for Year. Check in Moment Docs
let currentMilli = Date.now()
let today = Moment(currentMilli).format("D/M/Y");
let tomorrow = Moment(currentMilli).add(1, 'days').format("D/M/Y");
let yesterday = Moment(currentMilli).subtract(1, 'days').format("D/M/Y");
Result will be:
Current Milli - 1576693800000
today - 19/12/2019
tomorrow - 18/12/2019
yesterday - 18/12/2019

You can avoid the commas by using /-C on the DIR command.
FOR /F "usebackq tokens=3" %%s IN (`DIR C:\ /-C /-O /W`) DO (
SET FREE_SPACE=%%s
)
ECHO FREE_SPACE is %FREE_SPACE%
If you want to compare the available space to the space needed, you could do something like the following. I specified the number with thousands separator, then removed them. It is difficult to grasp the number without commas. The SET /A is nice, but it stops working with large numbers.
SET EXITCODE=0
SET NEEDED=100,000,000
SET NEEDED=%NEEDED:,=%
IF %FREE_SPACE% LSS %NEEDED% (
ECHO Not enough.
SET EXITCODE=1
)
EXIT /B %EXITCODE%
IMHO, fs.readFile()
should be avoided because it loads ALL the file in memory and it won't call the callback until all the file has been read.
The easiest way to read a text file is to read it line by line. I recommend a BufferedReader:
new BufferedReader ("file", { encoding: "utf8" })
.on ("error", function (error){
console.log ("error: " + error);
})
.on ("line", function (line){
console.log ("line: " + line);
})
.on ("end", function (){
console.log ("EOF");
})
.read ();
For complex data structures like .properties or json files you need to use a parser (internally it should also use a buffered reader).
It's been a while but the question is still relevant, though the answer might have changed a bit.
An API Gateway would be a flexible and highly configurable solution. I tested and used KONG quite a bit and really liked what I saw. KONG provides an admin REST API of its own which you can use to manage users.
Express-gateway.io is more recent and is also an API Gateway.

Not sure why is this complicated. I would do this basic javascript
<body onresize='document.getElementsByTagName("body")[0].style[ "font-size" ] = document.body.clientWidth*(12/1280) + "px";'>
Where 12 means 12px at 1280 resolution. You decide the value you want here
type="text/javascript"
This attribute is optional. Since Netscape 2, the default programming language in all browsers has been JavaScript. In XHTML, this attribute is required and unnecessary. In HTML, it is better to leave it out. The browser knows what to do.
W3C did not adopt the
language
attribute, favoring instead atype
attribute which takes a MIME type. Unfortunately, the MIME type was not standardized, so it is sometimes"text/javascript"
or"application/ecmascript"
or something else. Fortunately, all browsers will always choose JavaScript as the default programming language, so it is always best to simply write<script>
. It is smallest, and it works on the most browsers.
For entertainment purposes only, I tried out the following five scripts
<script type="application/ecmascript">alert("1");</script>
<script type="text/javascript">alert("2");</script>
<script type="baloney">alert("3");</script>
<script type="">alert("4");</script>
<script >alert("5");</script>
On Chrome, all but script 3 (type="baloney"
) worked. IE8 did not run script 1 (type="application/ecmascript"
) or script 3. Based on my non-extensive sample of two browsers, it looks like you can safely ignore the type
attribute, but that it you use it you better use a legal (browser dependent) value.
simple way to do this in one line of code would be this
string sub = input.Substring(input.Length > 5 ? input.Length - 5 : 0);

Try float(a)/b
Instead of instantiating the FileUpload
in your code behind file, just declare it in your markup file (.aspx file):
<asp:FileUpload ID="fileUpload" runat="server" />
Then you will be able to access all of the properties of the control, such as HasFile
.
Just combine them. I think this should work but it's untested:
p <- ggplot(visual1, aes(ISSUE_DATE,COUNTED)) + geom_point() +
geom_smooth(fill="blue", colour="darkblue", size=1)
p <- p + geom_point(data=visual2, aes(ISSUE_DATE,COUNTED)) +
geom_smooth(data=visual2, fill="red", colour="red", size=1)
print(p)
This is the shortest I could find.
List version
public List<Integer> makeSequence(int begin, int end)
{
List<Integer> ret = new ArrayList<Integer>(++end - begin);
for (; begin < end; )
ret.add(begin++);
return ret;
}
Array Version
public int[] makeSequence(int begin, int end)
{
if(end < begin)
return null;
int[] ret = new int[++end - begin];
for (int i=0; begin < end; )
ret[i++] = begin++;
return ret;
}
You can use Java 8 collectors and TreeSet
list.stream().collect(Collectors.toCollection(TreeSet::new))
You can use javascript Spread Syntax to convert string to an array. In the solution below, I remove the comma then convert the string to an array.
var string = "0,1"
var array = [...string.replace(',', '')]
console.log(array[0])
Its as simple as if([myString isEqual:@""])
or if([myString isEqualToString:@""])
In [7]: %%timeit dic = {str(i):i for i in xrange(10)}; dic['10'] = None; dic['5'] = None
...: dic = {k: v for k, v in dic.items() if v is not None}
1000000 loops, best of 7: 375 ns per loop
In [8]: %%timeit dic = {str(i):i for i in xrange(10)}; dic['10'] = None; dic['5'] = None
...: dic = dict((k, v) for k, v in dic.items() if v is not None)
1000000 loops, best of 7: 681 ns per loop
In [10]: %%timeit dic = {str(i):i for i in xrange(10)}; dic['10'] = None; dic['5'] = None
...: for k, v in dic.items():
...: if v is None:
...: del dic[k]
...:
10000000 loops, best of 7: 160 ns per loop
so loop and delete is the fastest at 160ns, list comprehension is half as slow at ~375ns and with a call to dict()
is half as slow again ~680ns.
Wrapping 3 into a function brings it back down again to about 275ns. Also for me PyPy was about twice as fast as neet python.
Overwrite the brand class, either in the bootstrap.css or a new CSS file, as below -
.brand

}
and your html should look like -
<div class="container-fluid">

This is very simple If you have already set a remote origin url then you use
set-url
command to change that, otherwise simply useadd
command
git remote -v
Check if any remote already existsgit remote set-url origin [email protected]:User/UserRepo.git
to change the origingit remote add origin [email protected]:User/UserRepo.git
to set new origin for your repo.git push -u origin master
to push your code to remote and add upstream (tracking) reference to your remote branch.NOTE: If you use -u
flag, its for upstream, it enables you to use simply git pull
instead of git pull origin <branch-name>
in upcoming operations.
Happy Coding ;)
I use this one:
LocationManager.requestLocationUpdates(String provider, long minTime, float minDistance, LocationListener listener)
For example, using a 1s interval:
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
the time is in milliseconds, the distance is in meters.
This automatically calls:
public void onLocationChanged(Location location) {
//Code here, location.getAccuracy(), location.getLongitude() etc...
}
I also had these included in the script but didnt actually use them:
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
In short:
public class GPSClass implements LocationListener {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
Log.i("Message: ","Location changed, " + location.getAccuracy() + " , " + location.getLatitude()+ "," + location.getLongitude());
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
locationManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,1000,0,this);
}
}
With these types of things, it's much better to be explicit about what you want and do not want.
It will help the next guy to not get caught by surprise at the behaviour of array_filter()
without a callback. For example, I ended up on this question because I forgot if array_filter()
removes NULL
or not. I wasted time when I could have just used the solution below and had my answer.
Also, the logic is language angnostic in the sense that the code can be copied into another language without having to under stand the behaviour of a php function like array_filter
when no callback is passed.
In my solution, it is clear at glance as to what is happening. Remove a conditional to keep something or add a new condition to filter additional values.
Disregard the actual use of array_filter()
since I am just passing it a custom callback - you could go ahead and extract that out to its own function if you wanted. I am just using it as sugar for a foreach
loop.
<?php
$xs = [0, 1, 2, 3, "0", "", false, null];
$xs = array_filter($xs, function($x) {
if ($x === null) { return false; }
if ($x === false) { return false; }
if ($x === "") { return false; }
if ($x === "0") { return false; }
return true;
});
$xs = array_values($xs); // reindex array
echo "<pre>";
var_export($xs);
Another benefit of this approach is that you can break apart the filtering predicates into an abstract function that filters a single value per array and build up to a composable solution.
See this example and the inline comments for the output.
<?php
/**
* @param string $valueToFilter
*
* @return \Closure A function that expects a 1d array and returns an array
* filtered of values matching $valueToFilter.
*/
function filterValue($valueToFilter)
{
return function($xs) use ($valueToFilter) {
return array_filter($xs, function($x) use ($valueToFilter) {
return $x !== $valueToFilter;
});
};
}
// partially applied functions that each expect a 1d array of values
$filterNull = filterValue(null);
$filterFalse = filterValue(false);
$filterZeroString = filterValue("0");
$filterEmptyString = filterValue("");
$xs = [0, 1, 2, 3, null, false, "0", ""];
$xs = $filterNull($xs); //=> [0, 1, 2, 3, false, "0", ""]
$xs = $filterFalse($xs); //=> [0, 1, 2, 3, "0", ""]
$xs = $filterZeroString($xs); //=> [0, 1, 2, 3, ""]
$xs = $filterEmptyString($xs); //=> [0, 1, 2, 3]
echo "<pre>";
var_export($xs); //=> [0, 1, 2, 3]
Now you can dynamically create a function called filterer()
using pipe()
that will apply these partially applied functions for you.
<?php
/**
* Supply between 1..n functions each with an arity of 1 (that is, accepts
* one and only one argument). Versions prior to php 5.6 do not have the
* variadic operator `...` and as such require the use of `func_get_args()` to
* obtain the comma-delimited list of expressions provided via the argument
* list on function call.
*
* Example - Call the function `pipe()` like:
*
* pipe ($addOne, $multiplyByTwo);
*
* @return closure
*/
function pipe()
{
$functions = func_get_args(); // an array of callable functions [$addOne, $multiplyByTwo]
return function ($initialAccumulator) use ($functions) { // return a function with an arity of 1
return array_reduce( // chain the supplied `$arg` value through each function in the list of functions
$functions, // an array of functions to reduce over the supplied `$arg` value
function ($accumulator, $currFn) { // the reducer (a reducing function)
return $currFn($accumulator);
},
$initialAccumulator
);
};
}
/**
* @param string $valueToFilter
*
* @return \Closure A function that expects a 1d array and returns an array
* filtered of values matching $valueToFilter.
*/
function filterValue($valueToFilter)
{
return function($xs) use ($valueToFilter) {
return array_filter($xs, function($x) use ($valueToFilter) {
return $x !== $valueToFilter;
});
};
}
$filterer = pipe(
filterValue(null),
filterValue(false),
filterValue("0"),
filterValue("")
);
$xs = [0, 1, 2, 3, null, false, "0", ""];
$xs = $filterer($xs);
echo "<pre>";
var_export($xs); //=> [0, 1, 2, 3]
You should either use
if str1[0] == '"' and str1[-1] == '"'
or
if str1.startswith('"') and str1.endswith('"')
but not slice and check startswith/endswith together, otherwise you'll slice off what you're looking for...
It is important to highlight that the Property (MaximumErrorCount) that needs to be changed must be set as more than 0 (which is the default) in the Package level and not in the specific control that is showing the error (I tried this and it does not work!)
Be sure that in the Properties Window, the Pull down menu is set to "Package", then look for the property MaximumErrorCount to change it.
>>> print "%r, %r" % (True, False)
True, False
This is not specific to boolean values - %r
calls the __repr__
method on the argument. %s
(for str
) should also work.
Regarding #2, according to the JSR-330 spec:
This package provides dependency injection annotations that enable portable classes, but it leaves external dependency configuration up to the injector implementation.
So it's up to the provider to determine which objects are available for injection. In the case of Spring it is all Spring beans. And any class annotated with JSR-330 annotations are automatically added as Spring beans when using an AnnotationConfigApplicationContext.
cPickle
comes with the standard library… in python 2.x. You are on python 3.x, so if you want cPickle
, you can do this:
>>> import _pickle as cPickle
However, in 3.x, it's easier just to use pickle
.
No need to install anything. If something requires cPickle
in python 3.x, then that's probably a bug.
An event in .net is a designated combination of an Add method and a Remove method, both of which expect some particular type of delegate. Both C# and vb.net can auto-generate code for the add and remove methods which will define a delegate to hold the event subscriptions, and add/remove the passed in delegagte to/from that subscription delegate. VB.net will also auto-generate code (with the RaiseEvent statement) to invoke the subscription list if and only if it is non-empty; for some reason, C# doesn't generate the latter.
Note that while it is common to manage event subscriptions using a multicast delegate, that is not the only means of doing so. From a public perspective, a would-be event subscriber needs to know how to let an object know it wants to receive events, but it does not need to know what mechanism the publisher will use to raise the events. Note also that while whoever defined the event data structure in .net apparently thought there should be a public means of raising them, neither C# nor vb.net makes use of that feature.
One way to do it will be to move all the php code above the HTML, copy the result to a variable and then add the result in the <input>
tag.
Try this -
<?php
//Adding the php to the top.
if(isset($_POST['submit']))
{
$value1=$_POST['value1'];
$value2=$_POST['value2'];
$sign=$_POST['sign'];
...
//Adding to $result variable
if($sign=='-') {
$result = $value1-$value2;
}
//Rest of your code...
}
?>

Today I have experienced above issue saying
svn: run 'svn cleanup' to remove locks (type 'svn help cleanup' for details)
And here is my solution, got working
svn cleanup <Dir path of my SVN project code>
exmaple:
svn cleanup /Users/Ramdhan/SVN_Repo/ProjectName
Hope this will help.

When the normType
is NORM_MINMAX
, cv::normalize
normalizes _src
in such a way that the min value of dst
is alpha
and max value of dst
is beta
. cv::normalize
does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).
CV_8UC1
says how many channels dst
has.
The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize
What you can do is dynamically build the select string (the 'IN (?)' part) by a simple for loop as soon as you know how many values you need to put inside the IN clause. You can then instantiate the PreparedStatement.
You can use:
Object instance = new SomeClass();
instance.getClass().getName(); //will return the name (as String) (== "SomeClass")
instance.getClass(); //will return the SomeClass' Class object
HTH. But I think most of the time it is no good practice to use that for control flow or something similar...
For an oneliner, on linux or cygwin, you need to do public key authentication on the host, otherwise ssh will be asking for password.
gunzip -c numbers.sql.gz | ssh user@host mysql --user=user_name --password=your_password db_name
Or do port forwarding and connect to the remote mysql using a "local" connection:
ssh -L some_port:host:local_mysql_port user@host
then do the mysql connection on your local machine to localhost:some_port.
The port forwarding will work from putty too, with the similar -L option or you can configure it from the settings panel, somewhere down on the tree.
What your looking for is the DefaultListModel - Dynamic String List Variable.
Here is a whole class that uses the DefaultListModel as though it were the TStringList of Delphi. The difference is that you can add Strings to the list without limitation and you have the same ability at getting a single entry by specifying the entry int.

OutputAs methods are for outputting an entry as int, double, etc... so that you don't have to convert from string on the other side.
SaveFile & LoadFile are to save and load strings to and from files.
StrToList & ListToStr are to place delimiters between each entry.
ex. 1<>2<>3<>4<> if "<>" is the delimiter and 1 2 3 & 4 are the entries.
AddEntry & GetEntry are to add and get strings to and from the DefaultListModel.
RemoveEntry is to delete a string from the DefaultListModel.
You use the DefaultListModel instead of an array here like this:
DefaultListModel list = new DefaultListModel();
//now that you have a list, you can run it through the above class methods.
Question was more about XML but as annotation are more popular nowadays and it works similarly I'll show by example.
Let's create class Foo
:
public class Foo {
private String name;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
}
and two Configuration files (you can't create one):
@Configuration
public class Configuration1 {
@Bean
public Foo foo() {
Foo foo = new Foo();
foo.setName("configuration1");
return foo;
}
}
and
@Configuration
public class Configuration2 {
@Bean
public Foo foo() {
Foo foo = new Foo();
foo.setName("configuration2");
return foo;
}
}
and let's see what happens when calling foo.getName()
:
@SpringBootApplication
public class OverridingBeanDefinitionsApplication {
public static void main(String[] args) {
SpringApplication.run(OverridingBeanDefinitionsApplication.class, args);
AnnotationConfigApplicationContext applicationContext =
new AnnotationConfigApplicationContext(
Configuration1.class, Configuration2.class);
Foo foo = applicationContext.getBean(Foo.class);
System.out.println(foo.getName());
}
}
in this example result is: configuration2
.
The Spring Container gets all configuration metadata sources and merges bean definitions in those sources. In this example there are two @Bean
s. Order in which they are fed into ApplicationContext
decide. You can flip new AnnotationConfigApplicationContext(Configuration2.class, Configuration1.class);
and result will be configuration1
.
its simple let us assume you have made an state full class by extending Component which contains following
class DisableButton extends Components
{
constructor()
{
super();
// now set the initial state of button enable and disable to be false
this.state = {isEnable: false }
}
// this function checks the length and make button to be enable by updating the state
handleButtonEnable(event)
{
const value = this.target.value;
if(value.length > 0 )
{
// set the state of isEnable to be true to make the button to be enable
this.setState({isEnable : true})
}
}
// in render you having button and input
render()
{
return (
<div>
<input
placeholder={"ANY_PLACEHOLDER"}
onChange={this.handleChangePassword}
/>
<button
onClick ={this.someFunction}
disabled = {this.state.isEnable}
/>
<div/>
)
}
}
The issue appears with parsing the JSON from request body, tipical for an invalid JSON. If you're using curl on windows, try escaping the json like -d "{"name":"value"}"
or even -d "{"""name""":"value"""}"
On the other hand you can ommit the content-type header in which case whetewer is sent will be converted to your String argument
I had exactly the same problem, my solution was to use module definition file (.def) instead of __declspec(dllexport)
to define exports(http://msdn.microsoft.com/en-us/library/d91k01sh.aspx). I have no idea why this works, but it does
Look here http://docs.oracle.com/javase/6/docs/api/java/awt/Font.html#deriveFont%28float%29
JComponent has a setFont() method. You will control the font there, not on the String.
Such as
JButton b = new JButton();
b.setFont(b.getFont().deriveFont(18.0f));
DAO
is an abstraction of data persistence.
Repository
is an abstraction of a collection of objects.
DAO
would be considered closer to the database, often table-centric.
Repository
would be considered closer to the Domain, dealing only in Aggregate Roots.
Repository
could be implemented using DAO
's, but you wouldn't do the opposite.
Also, a Repository
is generally a narrower interface. It should be simply a collection of objects, with a Get(id)
, Find(ISpecification)
, Add(Entity)
.
A method like Update
is appropriate on a DAO
, but not a Repository
- when using a Repository
, changes to entities would usually be tracked by separate UnitOfWork.
It does seem common to see implementations called a Repository
that is really more of a DAO
, and hence I think there is some confusion about the difference between them.
using the Reflections library, it's easy as:
Reflections reflections = new Reflections("my.pkg", new SubTypesScanner(false));
That would scan all classes in the url/s that contains my.pkg package.
So, getting all classes is effectively getting all subtypes of Object, transitively:
Set<String> allClasses =
reflections.getStore().getSubTypesOf(Object.class.getName());
(The ordinary way reflections.getSubTypesOf(Object.class)
would cause loading all classes into PermGen and would probably throw OutOfMemoryError. you don't want to do it...)
If you want to get all direct subtypes of Object (or any other type), without getting its transitive subtypes all in once, use this:
Collection<String> directSubtypes =
reflections.getStore().get(SubTypesScanner.class).get(Object.class.getName());
Maybe you can use ListBuffers in scala to create empty list and add strings later because ListBuffers are mutable. Also all the List functions are available for the ListBuffers in scala.
import scala.collection.mutable.ListBuffer
val dm = ListBuffer[String]()
dm: scala.collection.mutable.ListBuffer[String] = ListBuffer()
dm += "text1"
dm += "text2"
dm = ListBuffer(text1, text2)
if you want you can convert this to a list by using .toList
Use --single-branch
option to only clone history leading to tip of the tag. This saves a lot of unnecessary code from being cloned.
git clone <repo_url> --branch <tag_name> --single-branch
Be very careful when using find
and sed
in a git repo! If you don't exclude the binary files you can end up with this error:
error: bad index file sha1 signature
fatal: index file corrupt
To solve this error you need to revert the sed
by replacing your new_string
with your old_string
. This will revert your replaced strings, so you will be back to the beginning of the problem.
The correct way to search for a string and replace it is to skip find
and use grep
instead in order to ignore the binary files:
sed -ri -e "s/old_string/new_string/g" $(grep -Elr --binary-files=without-match "old_string" "/files_dir")

This problem usually happen if eclipse accidentally compile the main.xml incorrectly. The easiest solution is to delete R.java inside gen directory. Once we delete, than eclipse will generate the new R.java base on the latest main.xml
This will alert on leaving current page

FWIW, Codegear C++Builder doesn't destruct in the expected order according to the standard.
C:\> sample.exe 1 2
Created in foo
Created in if
Destroyed in foo
Destroyed in if
... which is another reason not to rely on the destruction order!
shape
is a property of both numpy ndarray's and matrices.
A.shape
will return a tuple (m, n), where m is the number of rows, and n is the number of columns.
In fact, the numpy matrix
object is built on top of the ndarray
object, one of numpy's two fundamental objects (along with a universal function object), so it inherits from ndarray
You can try cactoos for that.
final InputStream input = new InputStreamOf("example");
The object is created with new
and not a static method for a reason.
Be careful that don't use [email protected]
or [email protected]
with [email protected]
. URL will update after history.push
or any other push to history instructions but navigation is not working with react-router
. use npm install [email protected]
to change the history version. see React router not working after upgrading to v 5.
I think this problem is happening when push to history happened. for example using <NavLink to="/apps">
facing a problem in NavLink.js that consume <RouterContext.Consumer>
. context.location
is changing to an object with action and location properties when the push to history occurs. So currentLocation.pathname
is null to match the path.
This basically covers all cases (make sure you have __init__.py
in relative/path/to/your/lib/folder):
import sys, os
sys.path.append(os.path.dirname(os.path.realpath(__file__)) + "/relative/path/to/your/lib/folder")
import someFileNameWhichIsInTheFolder
...
somefile.foo()
Example:
You have in your project folder:
/root/myproject/app.py
You have in another project folder:
/root/anotherproject/utils.py
/root/anotherproject/__init__.py
You want to use /root/anotherproject/utils.py
and call foo function which is in it.
So you write in app.py:
import sys, os
sys.path.append(os.path.dirname(os.path.realpath(__file__)) + "/../anotherproject")
import utils
utils.foo()
Try using zoom: 101%;
for complex designs when you can't use a combination of zoom + scale.
I solved it in my site making this in functions.php
add_action("template_redirect", "start_buffer");
add_action("shutdown", "end_buffer", 999);
function filter_buffer($buffer) {
$buffer = replace_insecure_links($buffer);
return $buffer;
}
function start_buffer(){
ob_start("filter_buffer");
}
function end_buffer(){
if (ob_get_length()) ob_end_flush();
}
function replace_insecure_links($str) {
$str = str_replace ( array("http://www.yoursite.com/", "https://www.yoursite.com/") , array("/", "/"), $str);
return apply_filters("rsssl_fixer_output", $str);
}
I took part of one plugin, cut it into pieces and make this. It replaced ALL links in my site (menus, css, scripts etc.) and everything was working.
A simple way for doing this could be
double d = 7.88; //sample example
int x=floor(d); //floor of number
int y=ceil(d); //ceil of number
if(x==y) //both floor and ceil will be same for integer number
cout<<"integer number";
else
cout<<"double number";
Your .htaccess
is slightly off. Look at mine:
RewriteEngine On
RewriteBase /codeigniter
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond $1 !^(index\.php|images|robots\.txt|css|docs|js|system)
RewriteRule ^(.*)$ /codeigniter/index.php?/$1 [L]
Notice "codeigniter" in two places.
after that, in your config:
base_url = "http://localhost/codeigniter"
index = ""
Change codeigniter to "ci" whereever appropriate
Iteration vs Space, usage could be an issue. In different situations profiling may show either to be "faster" and/or "less memory" intensive.
# first
>>> L = [0, 23, 234, 89, None, 0, 35, 9, ...]
>>> [x for x in L if x is not None]
[0, 23, 234, 89, 0, 35, 9, ...]
# second
>>> L = [0, 23, 234, 89, None, 0, 35, 9]
>>> for i in range(L.count(None)): L.remove(None)
[0, 23, 234, 89, 0, 35, 9, ...]
The first approach (as also suggested by @jamylak, @Raymond Hettinger, and @Dipto) creates a duplicate list in memory, which could be costly of memory for a large list with few None
entries.
The second approach goes through the list once, and then again each time until a None
is reached. This could be less memory intensive, and the list will get smaller as it goes. The decrease in list size could have a speed up for lots of None
entries in the front, but the worst case would be if lots of None
entries were in the back.
The second approach would likely always be slower than the first approach. That does not make it an invalid consideration.
Parallelization and in-place techniques are other approaches, but each have their own complications in Python. Knowing the data and the runtime use-cases, as well profiling the program are where to start for intensive operations or large data.
Choosing either approach will probably not matter in common situations. It becomes more of a preference of notation. In fact, in those uncommon circumstances, numpy
(example if L is numpy.array: L = L[L != numpy.array(None)
(from here)) or cython
may be worthwhile alternatives instead of attempting to micromanage Python optimizations.

Double check the fields in the relationship the foreign key is defined for. SQL Server Management Studio may not have had the fields you wanted selected when you defined the relationship. This has burned me in the past.
UPDATE:
Like @jack-marchetti stated in his comment, and @devantoine with the link: https://developers.facebook.com/x/bugs/357750474364812/
Facebook has changed how the sharer.php works, as Ibrahim Faour replies to the bug filed with Facebook.
The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post, from the url OG meta tags.
Try this (via Javascript in this example):
'http://www.facebook.com/sharer.php?s=100&p[title]='+encodeURIComponent('this is a title') + '&p[summary]=' + encodeURIComponent('description here') + '&p[url]=' + encodeURIComponent('http://www.nufc.com') + '&p[images][0]=' + encodeURIComponent('http://www.somedomain.com/image.jpg')
I tried this quickly without the image part and the sharer.php window appears pre-populated, so it looks like a solution.
I found this via this SO article:
Want custom title / image / description in facebook share link from a flash app
and this link contained in an answer from Lelis718:
so all credit to Lelis718 for this answer.
[EDIT 3rd May 2013] - seems like the original URL i had here no longer works for me without also including "s=100" in the query string - no idea why but have updated accordingly
An object of a class cannot be set to NULL; however, you can set a pointer (which contains a memory address of an object) to NULL.
Example of what you can't do which you are asking:
Cat c;
c = NULL;//Compiling error
Example of what you can do:
Cat c;
//Set p to hold the memory address of the object c
Cat *p = &c;
//Set p to hold NULL
p = NULL;
