HTTP HEAD requests must be treated slightly differently because response.getEntity() is null. Instead, you must capture the HttpContext passed into HttpClient.execute() and retrieve the connection parameter to close it (in HttpComponents 4.1.X anyway).
HttpRequest httpRqst = new HttpHead( uri );
HttpContext httpContext = httpFactory.createContext();
HttpResponse httpResp = httpClient.execute( httpRqst, httpContext );
...
// Close when finished
HttpEntity entity = httpResp.getEntity();
if( null != entity )
// Handles standard 'GET' case
EntityUtils.consume( entity );
else {
ConnectionReleaseTrigger conn =
(ConnectionReleaseTrigger) httpContext.getAttribute( ExecutionContext.HTTP_CONNECTION );
// Handles 'HEAD' where entity is not returned
if( null != conn )
conn.releaseConnection();
}
HttpComponents 4.2.X added a releaseConnection() to HttpRequestBase to make this easier.

The javax.mail-api
artifact is only good for compiling against.
You actually need to run code, so you need a complete implementation of JavaMail API. Use this:
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
</dependency>
NOTE: The version number will probably differ. Check the latest version here.
I wrote this method:
private string GetUrlParameter(HttpRequestBase request, string parName)
{
string result = string.Empty;
var urlParameters = HttpUtility.ParseQueryString(request.Url.Query);
if (urlParameters.AllKeys.Contains(parName))
{
result = urlParameters.Get(parName);
}
return result;
}
And I call it like this:
string fooBar = GetUrlParameter(Request, "FooBar");
if (!string.IsNullOrEmpty(fooBar))
{
}
This should do it:
//Returns the index of the first occurence of char c in char* string. If not found -1 is returned.
int get_index(char* string, char c) {
char *e = strchr(string, c);
if (e == NULL) {
return -1;
}
return (int)(e - string);
}
J.Random Coder's answer and initialize version field.
private string version = "10.4';
Call this in the project:
svn diff -r REVNO:HEAD --summarize
REVNO
is the start revision number and HEAD
is the end revision number. If HEAD is equal to the last revision number, it can skip it.
The command returns a list with all files that are changed/added/deleted in this revision period.
The command can be called with the URL revision parameter to check changes like this:
svn diff -r REVNO:HEAD --summarize SVN_URL
UPDATE
You can use document.location.reload(true)
as mentioned below instead of the forced trick below.
Replace your HTML with this:
<!DOCTYPE html>

var page_y = document.getElementsByTagName("body")[0].scrollTop;
window.location.href = window.location.href.split('?')[0] + '?page_y=' + page_y;
}
window.onload = function () {
setTimeout(refreshPage, 35000);
if ( window.location.href.indexOf('page_y') != -1 ) {
var match = window.location.href.split('?')[1].split("&")[0].split("=");
document.getElementsByTagName("body")[0].scrollTop = match[1];

Using the keyword "use" is for shortening namespace literals. You can use both with aliasing and without it. Without aliasing you must use last part of full namespace.
<?php
use foo\bar\lastPart;
$obj=new lastPart\AnyClass(); //If there's not the line above, a fatal error will be encountered.
?>
I uninstalled Intel HAXM and VirtualBox, Docker now runs
For variables describing distances, you would use \newlength
(and manipulate the values with \setlength
, \addlength
, \settoheight
, \settolength
and \settodepth
).
Similarly you have access to \newcounter
for things like section and figure numbers which should increment throughout the document. I've used this one in the past to provide code samples that were numbered separatly of other figures...
Also of note is \makebox
which allows you to store a bit of laid-out document for later re-use (and for use with \settolength
...).
As noted by S.Lott,
Variable set outside init belong to the class. They're shared by all instances.
Variables created inside init (and all other method functions) and prefaced with self. belong to the object instance.
However, Note that class variables can be accessed via self.<var> until they are masked by an object variable with a similar name This means that reading self.<var> before assigning it a value will return the value of Class.<var> but afterwards it will return obj.<var> . Here is an example
In [20]: class MyClass:
...: elem = 123
...:
...: def update(self,i):
...: self.elem=i
...: def print(self):
...: print (MyClass.elem, self.elem)
...:
...: c1 = MyClass()
...: c2 = MyClass()
...: c1.print()
...: c2.print()
123 123
123 123
In [21]: c1.update(1)
...: c2.update(42)
...: c1.print()
...: c2.print()
123 1
123 42
In [22]: MyClass.elem=22
...: c1.print()
...: c2.print()
22 1
22 42
Second note: Consider slots. They may offer a better way to implement object variables.
Using recursion:
function isPalindromeRecursive(str) {
const isLessThan2 = str.length < 2;
const firstAndLastEqual = str.slice(0, 1) === str.slice(-1);
return !isLessThan2 && firstAndLastEqual
? isPalindromeRecursive(str.slice(1, -1))
: isLessThan2;
}

It is cumbersome to interoperate socket.io and connect sessions support. The problem is not because socket.io "hijacks" request somehow, but because certain socket.io transports (I think flashsockets) don't support cookies. I could be wrong with cookies, but my approach is the following:
@Sanjeet Gupta answer is good but could be condensed. This question is specifically asking about the "Fastest" way but I only see times on one answer so I'll post a comparison of using scipy and numpy to the original poster's entropy2 answer with slight alterations.
Four different approaches: scipy/numpy, numpy/math, pandas/numpy, numpy
import numpy as np
from scipy.stats import entropy
from math import log, e
import pandas as pd
import timeit
def entropy1(labels, base=None):
value,counts = np.unique(labels, return_counts=True)
return entropy(counts, base=base)
def entropy2(labels, base=None):
""" Computes entropy of label distribution. """
n_labels = len(labels)
if n_labels <= 1:
return 0
value,counts = np.unique(labels, return_counts=True)
probs = counts / n_labels
n_classes = np.count_nonzero(probs)
if n_classes <= 1:
return 0
ent = 0.
# Compute entropy
base = e if base is None else base
for i in probs:
ent -= i * log(i, base)
return ent
def entropy3(labels, base=None):
vc = pd.Series(labels).value_counts(normalize=True, sort=False)
base = e if base is None else base
return -(vc * np.log(vc)/np.log(base)).sum()
def entropy4(labels, base=None):
value,counts = np.unique(labels, return_counts=True)
norm_counts = counts / counts.sum()
base = e if base is None else base
return -(norm_counts * np.log(norm_counts)/np.log(base)).sum()
Timeit operations:
repeat_number = 1000000
a = timeit.repeat(stmt='''entropy1(labels)''',
setup='''labels=[1,3,5,2,3,5,3,2,1,3,4,5];from __main__ import entropy1''',
repeat=3, number=repeat_number)
b = timeit.repeat(stmt='''entropy2(labels)''',
setup='''labels=[1,3,5,2,3,5,3,2,1,3,4,5];from __main__ import entropy2''',
repeat=3, number=repeat_number)
c = timeit.repeat(stmt='''entropy3(labels)''',
setup='''labels=[1,3,5,2,3,5,3,2,1,3,4,5];from __main__ import entropy3''',
repeat=3, number=repeat_number)
d = timeit.repeat(stmt='''entropy4(labels)''',
setup='''labels=[1,3,5,2,3,5,3,2,1,3,4,5];from __main__ import entropy4''',
repeat=3, number=repeat_number)
Timeit results:
# for loop to print out results of timeit
for approach,timeit_results in zip(['scipy/numpy', 'numpy/math', 'pandas/numpy', 'numpy'], [a,b,c,d]):
print('Method: {}, Avg.: {:.6f}'.format(approach, np.array(timeit_results).mean()))
Method: scipy/numpy, Avg.: 63.315312
Method: numpy/math, Avg.: 49.256894
Method: pandas/numpy, Avg.: 884.644023
Method: numpy, Avg.: 60.026938
Winner: numpy/math (entropy2)
It's also worth noting that the entropy2
function above can handle numeric AND text data. ex: entropy2(list('abcdefabacdebcab'))
. The original poster's answer is from 2013 and had a specific use-case for binning ints but it won't work for text.
May be, it is not the very worst idea to merge (via difftool) from ... yes ... a branch!
> current_branch=$(git status | head -n1 | cut -d' ' -f3)
> stash_branch="$current_branch-stash-$(date +%yy%mm%dd-%Hh%M)"
> git stash branch $stash_branch
> git checkout $current_branch
> git difftool $stash_branch
You can use any of:
cd ~/"My Code"
cd ~/M"y Code"
cd ~/My" Code"
You cannot use:
cd ~"/My Code"
The first works because the shell expands ~/ into $HOME/, and then tacks on My Code without the double quotes. The second fails because there isn't a user called '"
' (double quote) for ~"
to map to.
You can simply read each line from the file and assign it to an array.
#!/bin/bash
i=0
while read line
do
arr[$i]="$line"
i=$((i+1))
done < file.txt
Another option in case you don't wanna use a plugin:
Ctrl+` or
View -> Show Console
type on the console the following command:
view.encoding()
In case you want to something more intrusive, there's a option to create an shortcut that executes the following command:
sublime.message_dialog(view.encoding())
I don't understand what you want, but You can detect currently foreground/background application with ActivityManager.getRunningAppProcesses()
call.
Something like,
class ForegroundCheckTask extends AsyncTask<Context, Void, Boolean> {
@Override
protected Boolean doInBackground(Context... params) {
final Context context = params[0].getApplicationContext();
return isAppOnForeground(context);
}
private boolean isAppOnForeground(Context context) {
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
if (appProcesses == null) {
return false;
}
final String packageName = context.getPackageName();
for (RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND && appProcess.processName.equals(packageName)) {
return true;
}
}
return false;
}
}
// Use like this:
boolean foregroud = new ForegroundCheckTask().execute(context).get();
Also let me know if I misunderstand..
UPDATE: Look at this SO question Determining the current foreground application from a background task or service fore more information..
Thanks..
I had the same problem and solved like this: I deleted @Test annotation and retyped it. It just worked, I have no idea why.
You can combine both these actions and do Esc:wqEnter to save the commit and quit vim.
As an alternate to the above, you can also press ZZ while in the normal mode, which will save the file and exit vim. This is also easier for some people as it's the same key pressed twice.
public static void replaceFileString(String old, String new) throws IOException {
String fileName = Settings.getValue("fileDirectory");
FileInputStream fis = new FileInputStream(fileName);
String content = IOUtils.toString(fis, Charset.defaultCharset());
content = content.replaceAll(old, new);
FileOutputStream fos = new FileOutputStream(fileName);
IOUtils.write(content, new FileOutputStream(fileName), Charset.defaultCharset());
fis.close();
fos.close();
}
above is my implementation of Meriton's example that works for me. The fileName is the directory (ie. D:\utilities\settings.txt). I'm not sure what character set should be used, but I ran this code on a Windows XP machine just now and it did the trick without doing that temporary file creation and renaming stuff.
built-in types in Python have built in names:
>>> s = "hallo"
>>> type(s) is str
True
>>> s = {}
>>> type(s) is dict
True
btw note the is operator. However, type checking (if you want to call it that) is usually done by wrapping a type-specific test in a try-except clause, as it's not so much the type of the variable that's important, but whether you can do a certain something with it or not.
I simply copied my php_myslqli.dll file from ert folder back to php folder, and it worked for me after restarting my Apache and MySQL from the control Panel
Two methods:
You need to ask for the IP address that is bound to your eth0
interface. This is available from the netifaces package
import netifaces as ni
ni.ifaddresses('eth0')
ip = ni.ifaddresses('eth0')[ni.AF_INET][0]['addr']
print ip # should print "192.168.100.37"
You can also get a list of all available interfaces via
ni.interfaces()
Here's a way to get the IP address without using a python package:
import socket
import fcntl
import struct
def get_ip_address(ifname):
s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
return socket.inet_ntoa(fcntl.ioctl(
s.fileno(),
0x8915, # SIOCGIFADDR
struct.pack('256s', ifname[:15])
)[20:24])
get_ip_address('eth0') # '192.168.0.110'
Note: detecting the IP address to determine what environment you are using is quite a hack. Almost all frameworks provide a very simple way to set/modify an environment variable to indicate the current environment. Try and take a look at your documentation for this. It should be as simple as doing
if app.config['ENV'] == 'production':
#send production email
else:
#send development email
Nginx prefers prefix-based location matches (not involving regular expression), that's why in your code block, /stash redirects are going to /.
The algorithm used by Nginx to select which location to use is described thoroughly here: https://www.digitalocean.com/community/tutorials/understanding-nginx-server-and-location-block-selection-algorithms#matching-location-blocks
Have you tried using $("#<%= txtDateElementId.ClientID %>").datepicker(); instead of $("#txtDateElementId").datepicker(); when selecting an element by ID using JQuery.
To set JDK you can watch this video : how to set JDK . Then when you'll have JDK:
str_replace('"', "", $string);
str_replace("'", "", $string);
I assume you mean quotation marks?
Otherwise, go for some regex, this will work for html quotes for example:
preg_replace("/<!--.*?-->/", "", $string);
C-style quotes:
preg_replace("/\/\/.*?\n/", "\n", $string);
CSS-style quotes:
preg_replace("/\/*.*?\*\//", "", $string);
bash-style quotes:
preg-replace("/#.*?\n/", "\n", $string);
Etc etc...
As of Feb 2018, fetch()
can be cancelled with the code below on Chrome (read Using Readable Streams to enable Firefox support). No error is thrown for catch()
to pick up, and this is a temporary solution until AbortController
is fully adopted.
fetch('YOUR_CUSTOM_URL')
.then(response => {
if (!response.body) {
console.warn("ReadableStream is not yet supported in this browser. See https://developer.mozilla.org/en-US/docs/Web/API/ReadableStream")
return response;
}
// get reference to ReadableStream so we can cancel/abort this fetch request.
const responseReader = response.body.getReader();
startAbortSimulation(responseReader);
// Return a new Response object that implements a custom reader.
return new Response(new ReadableStream(new ReadableStreamConfig(responseReader)));
})
.then(response => response.blob())
.then(data => console.log('Download ended. Bytes downloaded:', data.size))
.catch(error => console.error('Error during fetch()', error))
// Here's an example of how to abort request once fetch() starts
function startAbortSimulation(responseReader) {
// abort fetch() after 50ms
setTimeout(function() {
console.log('aborting fetch()...');
responseReader.cancel()
.then(function() {
console.log('fetch() aborted');
})
},50)
}
// ReadableStream constructor requires custom implementation of start() method
function ReadableStreamConfig(reader) {
return {
start(controller) {
read();
function read() {
reader.read().then(({done,value}) => {
if (done) {
controller.close();
return;
}
controller.enqueue(value);
read();
})
}
}
}
}
There are various data structures which are optimized for adding elements at the first index. Mind though, that if you convert your collection to one of these, the conversation will probably need a time and space complexity of O(n)
The JDK includes the Deque
structure which offers methods like addFirst(e)
and offerFirst(e)
Deque<String> deque = new LinkedList<>();
deque.add("two");
deque.add("one");
deque.addFirst("three");
//prints "three", "two", "one"
Space and time complexity of insertion is with LinkedList
constant (O(1)
). See the Big-O cheatsheet.
A very easy but inefficient method is to use reverse:
Collections.reverse(list);
list.add(elementForTop);
Collections.reverse(list);
If you use Java 8 streams, this answer might interest you.
O(n)
O(1)
Looking at the JDK implementation this has a O(n)
time complexity so only suitable for very small lists.
try this ugly but workable solution:
// use CommonJS to export all keys
module.exports = { a: 1, b: 2, c: 3 };
// import by key
import { a, b, c } from 'commonjs-style-module';
console.log(a, b, c);
No. There is no such method in the standard Java SE class library.
The designers' view is that it is not needed in Java, since the language removes the need for an application1 to know about how much space needs to be reserved for a primitive value, an object or an array with a given number of elements.
You might think that a sizeof operator would be useful for people that need to know how much space their data structures take. However you can also get this information and more, simply and reliably using a Java memory profiler, so there is no need for a sizeof method.
Previous commenters made the point that sizeof(someType)
would be more readable than 4
. If you accept that readability argument, then the remedy is in your hands. Simply define a class like this ...
public class PrimitiveSizes {
public static int sizeof(byte b) { return 1; }
public static int sizeof(short s) { return 2; }
// etcetera
}
... and statically import it ...
import static PrimitiveSizes.*;
Or define some named constants; e.g.
public static final int SIZE_OF_INT = 4;
Or (Java 8 and later) use the Integer.BYTES
constant, and so on.
Why haven't the Java designers implemented this in standard libraries? My guess is that:
There is also the issue that the next demand would be for a sizeof(Object o)
method, which is fraught with technical difficulties.
The key word in the above is "they"!
1 - A programmer may need to know in order to design space efficient data structures. However, I can't imagine why that information would be needed in application code at runtime via a method call.
you might also like a more high-level approach (I have implemented and packaged as findtools):
from findtools.find_files import (find_files, Match)
# Recursively find all *.txt files in **/home/**
txt_files_pattern = Match(filetype='f', name='*.txt')
found_files = find_files(path='/home', match=txt_files_pattern)
for found_file in found_files:
print found_file
can be installed with
pip install findtools
def inside():
global var
var = 'info'
inside()
print(var)
>>>'info'
problem ended
Just to throw another variant into the mix, you can also use backquotes like this:
rm `find . -name *.pyc`
adb reboot
should not reboot your linux box.
But in any case, you can redirect the command to a specific adb device using adb -s <device_id> command
, where
Device ID can be obtained from the command adb devices
command in this case is reboot

Following @Erfan's good answer, most of the times in an analysis of aggregate values you want the unique possible combinations of these existing character values:
unique_chars = lambda x: ', '.join(x.unique())
(df
.groupby(['A'])
.agg({'C': unique_chars}))
Here is a practical example of how you could implement a running standard deviation with python and numpy
:
a = np.arange(1, 10)
s = 0
s2 = 0
for i in range(0, len(a)):
s += a[i]
s2 += a[i] ** 2
n = (i + 1)
m = s / n
std = np.sqrt((s2 / n) - (m * m))
print(std, np.std(a[:i + 1]))
This will print out the calculated standard deviation and a check standard deviation calculated with numpy:
0.0 0.0 0.5 0.5 0.8164965809277263 0.816496580927726 1.118033988749895 1.118033988749895 1.4142135623730951 1.4142135623730951 1.707825127659933 1.707825127659933 2.0 2.0 2.29128784747792 2.29128784747792 2.5819888974716116 2.581988897471611
I am just using the formula described in this thread:
stdev = sqrt((sum_x2 / n) - (mean * mean))
Beside the well-known (and already mentioned) System.currentTimeMillis()
and System.nanoTime()
there is also a neat library called perf4j which might be useful too, depending on your purpose of course.

This is a bit old, but I guess what you want is: ps -o pid -C PROCESS_NAME, for example:
ps -o pid -C bash
EDIT: Dependening on the sort of output you expect, pgrep
would be more elegant. This, in my knowledge, is Linux specific and result in similar output as above. For example:
pgrep bash
I agree with dfsq if all you want to do is show the button. If you want to switch between hiding and showing the button however, it is easier to use:
$("#buttonEditComment").toggleClass("hide");
I'm not so proud about this solution but you can have timestamp in microsecond or nanosecond in this way:
const microsecond = () => Number(Date.now() + String(process.hrtime()[1]).slice(3,6))
const nanosecond = () => Number(Date.now() + String(process.hrtime()[1]).slice(3))
// usage
microsecond() // return 1586878008997591
nanosecond() // return 1586878009000645600
// Benchmark with 100 000 iterations
// Date.now: 7.758ms
// microsecond: 33.382ms
// nanosecond: 31.252ms
Know that:
Date.now()
Date.now()
by Number(new Date())
to get timestamp in millisecondsEdit:
Here a solution to have microsecond with comma, however, the number version will be rounded natively by javascript. So if you want the same format every time, you should use the String version of it.
const microsecondWithCommaString = () => (Date.now() + '.' + String(process.hrtime()[1]).slice(3,7))
const microsecondWithComma = () => Number(Date.now() + '.' + String(process.hrtime()[1]).slice(3,7))
microsecondWithCommaString() // return "1586883629984.8997"
microsecondWithComma() // return 1586883629985.966
I've implemented a library with a category on UIViewController that simplifies this operation. Basically, you set the parameters you want to pass over in a NSDictionary associated to the UI item that is performing the segue. It works with manual segues too.
For example, you can do
[self performSegueWithIdentifier:@"yourIdentifier" parameters:@{@"customParam1":customValue1, @"customValue2":customValue2}];
for a manual segue or create a button with a segue and use
[button setSegueParameters:@{@"customParam1":customValue1, @"customValue2":customValue2}];
If destination view controller is not key-value coding compliant for a key, nothing happens. It works with key-values too (useful for unwind segues). Check it out here https://github.com/stefanomondino/SMQuickSegue
I would suggest creating a regex to do the job. You'll have to check for something like this: [a-zA-Z0-9+/=] You'll also have to check the length of the string. I'm not sure on this one, but i'm pretty sure if something gets trimmed (other than the padding "=") it would blow up.
Or better yet check out this stackoverflow question
You have a numpy array of strings, not floats. This is what is meant by dtype('<U9')
-- a little endian encoded unicode string with up to 9 characters.
try:
return sum(np.asarray(listOfEmb, dtype=float)) / float(len(listOfEmb))
However, you don't need numpy here at all. You can really just do:
return sum(float(embedding) for embedding in listOfEmb) / len(listOfEmb)
Or if you're really set on using numpy.
return np.asarray(listOfEmb, dtype=float).mean()

Once Indentator is installed, you can use Ctrl + Alt + I
It didn't work for me when I excluded SecurityAutoConfiguration using @SpringBootApplication annotation, but did work when I excluded it in @EnableAutoConfiguration:
@EnableAutoConfiguration(exclude = { SecurityAutoConfiguration.class })
I don't know if this is 'efficient', but it also works:
x = [1,2,3,4]
x.insert(0,x.pop())
EDIT: Hello again, I just found a big problem with this solution! Consider the following code:
class MyClass():
def __init__(self):
self.classlist = []
def shift_classlist(self): # right-shift-operation
self.classlist.insert(0, self.classlist.pop())
if __name__ == '__main__':
otherlist = [1,2,3]
x = MyClass()
# this is where kind of a magic link is created...
x.classlist = otherlist
for ii in xrange(2): # just to do it 2 times
print '\n\n\nbefore shift:'
print ' x.classlist =', x.classlist
print ' otherlist =', otherlist
x.shift_classlist()
print 'after shift:'
print ' x.classlist =', x.classlist
print ' otherlist =', otherlist, '<-- SHOULD NOT HAVE BIN CHANGED!'
The shift_classlist() method executes the same code as my x.insert(0,x.pop())-solution, otherlist is a list indipendent from the class. After passing the content of otherlist to the MyClass.classlist list, calling the shift_classlist() also changes the otherlist list:
CONSOLE OUTPUT:
before shift:
x.classlist = [1, 2, 3]
otherlist = [1, 2, 3]
after shift:
x.classlist = [3, 1, 2]
otherlist = [3, 1, 2] <-- SHOULD NOT HAVE BIN CHANGED!
before shift:
x.classlist = [3, 1, 2]
otherlist = [3, 1, 2]
after shift:
x.classlist = [2, 3, 1]
otherlist = [2, 3, 1] <-- SHOULD NOT HAVE BIN CHANGED!
I use Python 2.7. I don't know if thats a bug, but I think it's more likely that I missunderstood something here.
Does anyone of you know why this happens?
Facebook Login for Devices is for devices that directly make HTTP calls over the internet. The following are the API calls and responses your device can make.
1. Enable Login for Devices
Change Settings > Advanced > OAuth Settings > Login from Devices to 'Yes'.
2. Generate a Code which is required for facebook device identification
When the person clicks Log in with Facebook, you device should make an HTTP POST to:
POST https://graph.facebook.com/oauth/device?
type=device_code
&client_id=<YOUR_APP_ID>
&scope=<COMMA_SEPARATED_PERMISSION_NAMES> // e.g.public_profile,user_likes
The response comes in this form:
{
"code": "92a2b2e351f2b0b3503b2de251132f47",
"user_code": "A1NWZ9",
"verification_uri": "https://www.facebook.com/device",
"expires_in": 420,
"interval": 5
}
This response means:
3. Display the Code
Your device should display the user_code and tell people to visit the verification_uri such as facebook.com/device on their PC or smartphone. See the Design Guidelines.
4. Poll for Authorization
Your device should poll the Device Login API to see if the person successfully authorized your application. You should do this at the interval in the response to your call in Step 1, which is every 5 seconds. Your device should poll to:
POST https://graph.facebook.com/oauth/device?
type=device_token
&client_id=<YOUR_APP_ID>
&code=<LONG_CODE_FROM_STEP_1> //e.g."92a2b2e351f2b0b3503b2de251132f47"
You will get 200 HTTP code i.e User has successfully authorized the device. The device can now use the access_token value to make authenticated API calls.
5. Confirm Successful Login
Your device should display their name and if available, a profile picture until they click Continue. To get the person's name and profile picture, your device should make a standard Graph API call:
GET https://graph.facebook.com/v2.3/me?
fields=name,picture&
access_token=<USER_ACCESS_TOKEN>
Response:
{
"name": "John Doe",
"picture": {
"data": {
"is_silhouette": false,
"url": "https://fbcdn.akamaihd.net/hmac...ile.jpg"
}
},
"id": "2023462875238472"
}
6. Store Access Tokens
Your device should persist the access token to make other requests to the Graph API.
Device Login access tokens may be valid for up to 60 days but may be invalided in a number of scenarios. For example when a person changes their Facebook password their access token is invalidated.
If the token is invalid, your device should delete the token from its memory. The person using your device needs to perform the Device Login flow again from Step 1 to retrieve a new, valid token.
Its possible, but not directly.
In short, go to the search, use your regex, check "mark line" and click "Find all". It results in bookmarks for all those lines.
In the search menu there is a point "delete bookmarked lines" voila.
I found the answer here (the correct answer is the second one, not the accepted!): How to delete specific lines on Notepad++?
Two ways of dealing with it
div
inside tbody
tagdiv
inside tr
tagBoth approaches are valid, if you see feference: https://stackoverflow.com/a/23440419/2305243
You can't include server side PHP in your client side javascript, you will have to port it over to javascript. If you wish, you can use php.js, which ports all PHP functions over to javascript. You can also create a new php file that returns the results of calling your PHP function, and then call that file using AJAX to get the results.
Because the concept of a List is incompatible with the concept of an automatically sorted collection. The point of a List is that after calling list.add(7, elem)
, a call to list.get(7)
will return elem
. With an auto-sorted list, the element could end up in an arbitrary position.
You need the textFX plugin. Then, just follow these instructions:
Paste the text into Notepad++ (CTRL+V). ...
Mark all the text (CTRL+A). ...
Click TextFX ? Click TextFX Tools ? Click Sort lines case insensitive (at column)
Duplicates and blank lines have been removed and the data has been sorted alphabetically.
Personally, I would use sort -i -u source >dest instead of notepad++
For what it's worth, when I did this I found that no folder should be include in the path in the css file. For instance if I have app/assets/images/example.png
, and I put this in my css file...
div.example { background: url('example.png'); }
... then somehow it magically works. I figured this out by running the rake assets:precompile
task, which just sucks everything out of all your load paths and dumps it in a junk drawer folder: public/assets
. That's ironic, IMO...
In any case this means you don't need to put any folder paths, everything in your assets folders will all end up living in one huge directory. How this system resolves file name conflicts is unclear, you may need to be careful about that.
Kind of frustrating there aren't better docs out there for this big of a change.
I personally think that it's more important for the code to be readable and editable than performant. Whichever one you find easier to look at and it should be the one you choose for above factors. You can write it as:
$('#box').append(
$('<div/>')
.attr("id", "newDiv1")
.addClass("newDiv purple bloated")
.append("<span/>")
.text("hello world")
);
And your first Method as:
// create an element with an object literal, defining properties
var $e = $("<div>", {id: "newDiv1", name: 'test', class: "aClass"});
$e.click(function(){ /* ... */ });
// add the element to the body
$("#box").append($e);
But as far as readability goes; the jQuery approach is my favorite. Follow this Helpful jQuery Tricks, Notes, and Best Practices
WPF doesn't have a built-in property to hide the title bar's Close button, but you can do it with a few lines of P/Invoke.
First, add these declarations to your Window class:
private const int GWL_STYLE = -16;
private const int WS_SYSMENU = 0x80000;
[DllImport("user32.dll", SetLastError = true)]
private static extern int GetWindowLong(IntPtr hWnd, int nIndex);
[DllImport("user32.dll")]
private static extern int SetWindowLong(IntPtr hWnd, int nIndex, int dwNewLong);
Then put this code in the Window's Loaded
event:
var hwnd = new WindowInteropHelper(this).Handle;
SetWindowLong(hwnd, GWL_STYLE, GetWindowLong(hwnd, GWL_STYLE) & ~WS_SYSMENU);
And there you go: no more Close button. You also won't have a window icon on the left side of the title bar, which means no system menu, even when you right-click the title bar - they all go together.
Important note: all this does is hide the button. The user can still close the window! If the user presses Alt+F4, or closes the app via the taskbar, the window will still close.
If you don't want to allow the window to close before the background thread is done, then you could also override OnClosing
and set Cancel
to true, as Gabe suggested.
While Richard's is what you want if you do want to go with a typedef, I'd suggest that it's probably not a particularly good idea in this instance, as you lose sight of it being a pointer, while not gaining anything.
If you were treating it a a counted string, or something with additional functionality, that might be different, but I'd really recommend that in this instance, you just get familiar with the 'standard' C string implementation being a 'char *'...
MVC 5.1 and higher solution (will merge local HtmlAttributes and defined in the EditorTemplates):
Shared\EditorTemplates\String.cshtml:
@Html.TextBoxFor(model => model, new { @class = "form-control", placeholder = ViewData.ModelMetadata.Watermark }.ToExpando().MergeHtmlAttributes(ViewData["htmlAttributes"].ToExpando()))
Extensions:
public static IDictionary<string, object> MergeHtmlAttributes(this ExpandoObject source1, dynamic source2)
{
Condition.Requires(source1, "source1").IsNotNull().IsLongerThan(0);
IDictionary<string, object> result = source2 == null

Here is my technique I'd like to share. Works well so long as your clr property types are sql equivalent types eg. bool -> bit, long -> bigint, string -> nchar/char/varchar/nvarchar, decimal -> money

using (var con = new SqlConnection(ConfigurationManager.ConnectionStrings["ConString"].ConnectionString))

foreach (var prop in transaction.GetType().GetProperties(BindingFlags.Public | BindingFlags.Instance))
cmd.Parameters.AddWithValue("@" + prop.Name, prop.GetValue(transaction, null));
con.Open();
cmd.ExecuteNonQuery();
}
}
}

See the docs:
"For an explanation of why (on Windows) the if __name__ == '__main__'
part is necessary, see Programming guidelines."
which say
"Make sure that the main module can be safely imported by a new Python interpreter without causing unintended side effects (such a starting a new process)."

Internally, string::operator==()
is using string::compare()
. Please refer to: CPlusPlus - string::operator==()
I wrote a small application to compare the performance, and apparently if you compile and run your code on debug environment the string::compare()
is slightly faster than string::operator==()
. However if you compile and run your code in Release environment, both are pretty much the same.
FYI, I ran 1,000,000 iteration in order to come up with such conclusion.
In order to prove why in debug environment the string::compare is faster, I went to the assembly and here is the code:
DEBUG BUILD
string::operator==()
if (str1 == str2)
00D42A34 lea eax,[str2]
00D42A37 push eax
00D42A38 lea ecx,[str1]
00D42A3B push ecx
00D42A3C call std::operator==<char,std::char_traits<char>,std::allocator<char> > (0D23EECh)
00D42A41 add esp,8
00D42A44 movzx edx,al
00D42A47 test edx,edx
00D42A49 je Algorithm::PerformanceTest::stringComparison_usingEqualOperator1+0C4h (0D42A54h)
string::compare()
if (str1.compare(str2) == 0)
00D424D4 lea eax,[str2]
00D424D7 push eax
00D424D8 lea ecx,[str1]
00D424DB call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0D23582h)
00D424E0 test eax,eax
00D424E2 jne Algorithm::PerformanceTest::stringComparison_usingCompare1+0BDh (0D424EDh)
You can see that in string::operator==(), it has to perform extra operations (add esp, 8 and movzx edx,al)
RELEASE BUILD
string::operator==()
if (str1 == str2)
008533F0 cmp dword ptr [ebp-14h],10h
008533F4 lea eax,[str2]
008533F7 push dword ptr [ebp-18h]
008533FA cmovae eax,dword ptr [str2]
008533FE push eax
008533FF push dword ptr [ebp-30h]
00853402 push ecx
00853403 lea ecx,[str1]
00853406 call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0853B80h)
string::compare()
if (str1.compare(str2) == 0)
00853830 cmp dword ptr [ebp-14h],10h
00853834 lea eax,[str2]
00853837 push dword ptr [ebp-18h]
0085383A cmovae eax,dword ptr [str2]
0085383E push eax
0085383F push dword ptr [ebp-30h]
00853842 push ecx
00853843 lea ecx,[str1]
00853846 call std::basic_string<char,std::char_traits<char>,std::allocator<char> >::compare (0853B80h)
Both assembly code are very similar as the compiler perform optimization.
Finally, in my opinion, the performance gain is negligible, hence I would really leave it to the developer to decide on which one is the preferred one as both achieve the same outcome (especially when it is release build).
Run sudo visudo
command then set -%sudo ALL=(ALL:ALL)
to %sudo ALL=(ALL:ALL) NOPASSWD: ALL
it will work.
Just for an addition reference to the above answers. I can not use dpkg -L
to find the correct path for cuda.
See the results I got from dpkg -L
$ dpkg -L cuda
/.
/usr
/usr/share
/usr/share/doc
/usr/share/doc/cuda
/usr/share/doc/cuda/copyright
/usr/share/doc/cuda/changelog.Debian.gz
the correct path is /usr/local/cuda
$ ll /usr/local | grep cuda
lrwxrwxrwx 1 root root 8 Oct 20 18:45 cuda -> cuda-9.0/
drwxr-xr-x 15 root root 4096 Oct 20 18:44 cuda-9.0/
Btw, I did install cuda by the command of
dpkg -i xx_cuda_xxx.deb
Here is the same kind of code but using the third-party library Joda-Time 2.3.
In real life, I would specify a time zone, as relying on default zone is usually a bad practice. But omitted here for simplicity of example.
org.joda.time.DateTime now = new DateTime();
org.joda.time.format.DateTimeFormatter formatter = DateTimeFormat.forPattern( "MM/dd/yyyy h:mm:ss a" );
String nowAsString = formatter.print( now );
System.out.println( "nowAsString: " + nowAsString );
When run…
nowAsString: 11/28/2013 11:28:15 PM
There is a workaround.
That's it.
You need to call $compile
on the HTML string before inserting it into the DOM so that angular gets a chance to perform the binding.
In your fiddle, it would look something like this.
$("#dynamicContent").html(
$compile(
"<button ng-click='count = count + 1' ng-init='count=0'>Increment</button><span>count: {{count}} </span>"
)(scope)
);
Obviously, $compile
must be injected into your controller for this to work.
Read more in the $compile
documentation.
For me what it worked was:
sudo apt-get install socat
Create a file inside your $BIN_PATH/gitproxy with:
#!/bin/sh
_proxy=192.168.192.1
_proxyport=3128
exec socat STDIO PROXY:$_proxy:$1:$2,proxyport=$_proxyport
Dont forget to give it execution permissions
chmod a+x gitproxy
Run following commands to setup environment:
export PATH=$BIN_PATH:$PATH
git config --global core.gitproxy gitproxy
I launched ubuntu Xampp server on AWS amazon. And met the same problem with FTP, even though add user to group ftp SFTP and set permissions, owner group of htdocs folder. Finally find the reason in inbound rules in security group, added All TCP, 0 - 65535 rule(0.0.0.0/0,::/0) , then working right!
Workaround:
template<class T, size_t N>
struct simple_array { // like std::array in C++0x
T arr[N];
};
class C : private simple_array<int, 3>
{
static simple_array<int, 3> myarr() {
simple_array<int, 3> arr = {1,2,3};
return arr;
}
public:
C() : simple_array<int, 3>(myarr()) {}
};
I had given permissions I shouldn't have to write in some folders (especially /usr/bin/), and that caused the problem. I fixed it by opening Disk Utility and running 'Repair Disk Permissions' on the Macintosh HD disk.
This worked for me - if you have to log in Application_Start, do it before you modify the context. You will get a log entry, just with no source, like:
2019-03-12 09:35:43,659 INFO (null) - Application Started
I generally log both the Application_Start and Session_Start, so I see more detail in the next message
2019-03-12 09:35:45,064 INFO ~/Leads/Leads.aspx - Session Started (Local)
protected void Application_Start(object sender, EventArgs e)
{
log4net.Config.XmlConfigurator.Configure();
log.Info("Application Started");
GlobalContext.Properties["page"] = new GetCurrentPage();
}
protected void Session_Start(object sender, EventArgs e)
{
Globals._Environment = WebAppConfig.getEnvironment(Request.Url.AbsoluteUri, Properties.Settings.Default.LocalOverride);
log.Info(string.Format("Session Started ({0})", Globals._Environment));
}
Pragma directives specify operating system or machine specific (x86 or x64 etc) compiler options. There are several options available. Details can be found in https://msdn.microsoft.com/en-us/library/d9x1s805.aspx
#pragma comment( comment-type [,"commentstring"] )
has this format.
Refer https://msdn.microsoft.com/en-us/library/7f0aews7.aspx for details about different comment-type.
#pragma comment(lib, "kernel32")
#pragma comment(lib, "user32")
The above lines of code includes the library names (or path) that need to be searched by the linker. These details are included as part of the library-search record in the object file.
So, in this case kernel.lib
and user32.lib
are searched by the linker and included in the final executable.
Component: Subscribe to all routing events instead of creating an action in the template and scroll on NavigationEnd b/c otherwise you'll fire this off on bad navs or blocked routes, etc... This is a sure fire way to know that if a route successfully is navigated to, then sooth scroll. Otherwise, do nothing.
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit, OnDestroy {
router$: Subscription;
constructor(private router: Router) {}
ngOnInit() {
this.router$ = this.router.events.subscribe(next => this.onRouteUpdated(next));
}
ngOnDestroy() {
if (this.router$ != null) {
this.router$.unsubscribe();
}
}
private onRouteUpdated(event: any): void {
if (event instanceof NavigationEnd) {
this.smoothScrollTop();
}
}
private smoothScrollTop(): void {
const scrollToTop = window.setInterval(() => {
const pos: number = window.pageYOffset;
if (pos > 0) {
window.scrollTo(0, pos - 20); // how far to scroll on each step
} else {
window.clearInterval(scrollToTop);
}
}, 16);

Callable
interface declares call()
method and you need to provide generics as type of Object call() should return -
public interface Callable<V> {
/**
* Computes a result, or throws an exception if unable to do so.
*
* @return computed result
* @throws Exception if unable to compute a result
*/
V call() throws Exception;
}
Runnable
on the other hand is interface that declares run()
method that is called when you create a Thread with the runnable and call start() on it. You can also directly call run() but that just executes the run() method is same thread.
public interface Runnable {
/**
* When an object implementing interface <code>Runnable</code> is used
* to create a thread, starting the thread causes the object's
* <code>run</code> method to be called in that separately executing
* thread.
* <p>
* The general contract of the method <code>run</code> is that it may
* take any action whatsoever.
*
* @see java.lang.Thread#run()
*/
public abstract void run();
}
To summarize few notable Difference are
Runnable
object does not return a result whereas a Callable
object returns a result.Runnable
object cannot throw a checked exception wheras a Callable
object can throw an
exception.Runnable
interface has been around since Java 1.0 whereas Callable
was only introduced
in Java 1.5.Few similarities include
Methods in ExecutorService interface are
<T> Future<T> submit(Callable<T> task);
Future<?> submit(Runnable task);
<T> Future<T> submit(Runnable task, T result);
If you always need to know the length, and you just need the content of the match rather than the other info, you might as well use re.findall
. Otherwise, if you only need the length sometimes, you can use e.g.
matches = re.finditer(...)
...
matches = tuple(matches)
to store the iteration of the matches in a reusable tuple. Then just do len(matches)
.
Another option, if you just need to know the total count after doing whatever with the match objects, is to use
matches = enumerate(re.finditer(...))
which will return an (index, match)
pair for each of the original matches. So then you can just store the first element of each tuple in some variable.
But if you need the length first of all, and you need match objects as opposed to just the strings, you should just do
matches = tuple(re.finditer(...))
I use Mac and Idea 14.1.7. Found idea.vmoptions file here: /Applications/IntelliJ IDEA 14.app/Contents/bin
Renaming a worksheet manually in Excel, you hit a limit of 31 chars, so I'd suggest that that's a hard limit.
You're not parsing a string, you're parsing an already-parsed object :)
var obj1 = JSON.parse('{"creditBalance":0,...,"starStatus":false}');
// ^ ^
// if you want to parse, the input should be a string
var obj2 = {"creditBalance":0,...,"starStatus":false};
// or just use it directly.
I solved this issue by creating a new virtual device and launching it from the AVD manager. The device takes a few minutes to start, you just have to wait. Then you can run your application on the already started device.
We pull in content frequently from our CMS as [innerHTML]="content.title"
. We place the necessary classes in the application's root styles.scss
file rather than in the component's scss file. Our CMS purposely strips out in-line styles so we must have prepared classes that the author can use in their content. Remember using {{content.title}}
in the template will not render html from the content.
If you are planning to use appending more then once, you might want to write a function:
//Append text to input element
function jQ_append(id_of_input, text){
var input_id = '#'+id_of_input;
$(input_id).val($(input_id).val() + text);
}
After you can just call it:
jQ_append('my_input_id', 'add this text');
Use this higher order function to prevent the pyramid of doom
foreach(){
arr="$(declare -p $1)" ; eval "declare -A f="${arr#*=};
for i in ${!f[@]}; do $2 "$i" "${f[$i]}"; done
}
example:
$ bar(){ echo "$1 -> $2"; }
$ declare -A foo["flap"]="three four" foo["flop"]="one two"
$ foreach foo bar
flap -> three four
flop -> one two
I'd say use the PID for whatever purpose you're obtaining it and handle the errors gracefully. Otherwise, it's a classic race (the PID may be valid when you check it's valid, but go away an instant later)
There are mainly two possible ways to achieve this:
Serialize the data in some way:
$postvalue = serialize($array); // Client side
$array = unserialize($_POST['result']; // Server side
And then you can unserialize the posted values with unserialize($postvalue)
. Further information on this is here in the PHP manuals.
Alternativeley you can use the json_encode()
and json_decode()
functions to get a JSON formatted serialized string. You could even shrink the transmitted data with gzcompress()
(note that this is performance intensive) and secure the transmitted data with base64_encode()
(to make your data survive in non-8 bit clean transport layers) This could look like this:
$postvalue = base64_encode(json_encode($array)); // Client side
$array = json_decode(base64_decode($_POST['result'])); // Server side
A not recommended way to serialize your data (but very cheap in performance) is to simply use implode()
on your array to get a string with all values separated by some specified character. On the server side you can retrieve the array with explode()
then. But note that you shouldn't use a character for separation that occurs in the array values (or then escape it) and that you cannot transmit the array keys with this method.
Use the properties of special named input elements:
$postvalue = "";
foreach ($array as $v) {
$postvalue .= '<input type="hidden" name="result[]" value="' .$v. '" />';
}
Like this you get your entire array in the $_POST['result']
variable if the form is sent. Note that this doesn't transmit array keys. However you can achieve this by using result[$key]
as name of each field.
Everyone of these methods got their own advantages and disadvantages. What you use is mainly depending on how large your array will be, since you should try to send a minimal amount of data with all of this methods.
Another way to achieve the same is to store the array in a server side session instead of transmitting it client side. Like this you can access the array over the $_SESSION
variable and don't have to transmit anything over the form. For this have a look at a basic usage example of sessions on php.net.
In the past, there was something like: https: //jstl.dev.java.net/download.html. But since a few days, there is something happening on dev.java.net.
Java.net will be modified, read this: http: //www.java.net/. So I think we have to wait. I also found: http: //java.net/projects/help/pages/RequestedProjects.
Maybe this is helpful.
Another option is to look into the maven repository: http://repo1.maven.org/maven2/javax/servlet/
As already mentioned by Amro, the most concise way to do this is using cell arrays. However, Budo touched on the new string
class introduced in version R2016b of MATLAB. Using this new object, you can very easily create an array of strings in a loop as follows:
for i = 1:10
Names(i) = string('Sample Text');
end
Once I had this "simple" task and I used (new Date()).getTimezoneOffset()
- the approach that is widely suggested here. But it turned out that the solution wasn't quite right.
For some undocumented reasons in my case new Date()
was returning GMT+0200 when new Date(0)
was returning GMT+0300 which was right. Since then I always use
(new Date(0)).getTimezoneOffset()
to get a correct timeshift.

empty() used to work for this, but the behavior of empty() has changed several times. As always, the php docs are always the best source for exact behavior and the comments on those pages usually provide a good history of the changes over time. If you want to check for a lack of object properties, a very defensive method at the moment is:
if (is_object($theObject) && (count(get_object_vars($theObject)) > 0)) {
Here is my solution:
#include <stdexcept>
#include <sstream>
class Formatter
{
public:
Formatter() {}
~Formatter() {}
template <typename Type>
Formatter & operator << (const Type & value)
{
stream_ << value;
return *this;
}
std::string str() const { return stream_.str(); }
operator std::string () const { return stream_.str(); }
enum ConvertToString
{
to_str
};
std::string operator >> (ConvertToString) { return stream_.str(); }
private:
std::stringstream stream_;
Formatter(const Formatter &);
Formatter & operator = (Formatter &);
};
Example:
throw std::runtime_error(Formatter() << foo << 13 << ", bar" << myData); // implicitly cast to std::string
throw std::runtime_error(Formatter() << foo << 13 << ", bar" << myData >> Formatter::to_str); // explicitly cast to std::string
Neither collection will let you add items that way.
You can make an extension to make for examle List(Of String)
have an Add
method that can do that:
Imports System.Runtime.CompilerServices
Module StringExtensions
<Extension()>
Public Sub Add(ByVal list As List(Of String), ParamArray values As String())
For Each s As String In values
list.Add(s)
Next
End Sub
End Module
Now you can add multiple value in one call:
Dim lstOfStrings as New List(Of String)
lstOfStrings.Add(String1, String2, String3, String4)
this is how:
/**
* Get a web file (HTML, XHTML, XML, image, etc.) from a URL. Return an
* array containing the HTTP server response header fields and content.
*/
function get_web_page( $url )
{
$user_agent='Mozilla/5.0 (Windows NT 6.1; rv:8.0) Gecko/20100101 Firefox/8.0';
$options = array(
CURLOPT_CUSTOMREQUEST =>"GET", //set request type post or get
CURLOPT_POST =>false, //set to GET
CURLOPT_USERAGENT => $user_agent, //set user agent
CURLOPT_COOKIEFILE =>"cookie.txt", //set cookie file
CURLOPT_COOKIEJAR =>"cookie.txt", //set cookie jar
CURLOPT_RETURNTRANSFER => true, // return web page
CURLOPT_HEADER => false, // don't return headers

CURLOPT_ENCODING => "", // handle all encodings
CURLOPT_AUTOREFERER => true, // set referer on redirect
CURLOPT_CONNECTTIMEOUT => 120, // timeout on connect
CURLOPT_TIMEOUT => 120, // timeout on response
CURLOPT_MAXREDIRS => 10, // stop after 10 redirects
);
$ch = curl_init( $url );
curl_setopt_array( $ch, $options );
$content = curl_exec( $ch );
$err = curl_errno( $ch );
$errmsg = curl_error( $ch );
$header = curl_getinfo( $ch );
curl_close( $ch );
$header['errno'] = $err;
$header['errmsg'] = $errmsg;
$header['content'] = $content;
return $header;
}
Example
//Read a web page and check for errors:
$result = get_web_page( $url );
if ( $result['errno'] != 0 )
... error: bad url, timeout, redirect loop ...
if ( $result['http_code'] != 200 )
... error: no page, no permissions, no service ...
$page = $result['content'];
When using most functions of objects with apply
or call
, the context
parameter MUST be the object you are working on.
In this case, you need a.push.apply(a, [1,2])
(or more correctly Array.prototype.push.apply(a, [1,2])
)
You can also do it using reredirect
(https://github.com/jerome-pouiller/reredirect/).
The command bellow redirects the outputs (standard and error) of the process PID
to FILE
:
reredirect -m FILE PID
The README
of reredirect
also explains other interesting features: how to restore the original state of the process, how to redirect to another command or to redirect only stdout or stderr.
The tool also provides relink
, a script allowing to redirect the outputs to the current terminal:
relink PID
relink PID | grep usefull_content
(reredirect
seems to have same features than Dupx described in another answer but, it does not depend on Gdb).
@media print {_x000D_
a[href]:after {_x000D_
display: none;_x000D_
visibility: hidden;_x000D_
}_x000D_
}
_x000D_
Work's perfect.
Below code will look for last used row in sheet1 and copy the entire range from A1 upto last used row in column A to Sheet2 at exact same location.
Sub test()
Dim lastRow As Long
lastRow = Sheets("Sheet1").Range("A" & Rows.Count).End(xlUp).Row
Sheets("Sheet2").Range("A1:A" & lastRow).Value = Sheets("Sheet1").Range("A1:A" & lastRow).Value
End Sub
It's the better way to connect to your redis.
At first, check the ip address of redis server like this.
ps -ef | grep redis
The result is kind of " redis 1184 1 0 .... /usr/bin/redis-server 172.x.x.x:6379
And then you can connect to redis with -h(hostname) option like this.
redis-cli -h 172.x.x.x
All of these answers appear to be incomplete and/or kludges. Looking at the RestTemplate interface, it sure looks like it is intended to have a ClientHttpRequestFactory
injected into it, and then that requestFactory will be used to create the request, including any customizations of headers, body, and request params.
You either need a universal ClientHttpRequestFactory
to inject into a single shared RestTemplate
or else you need to get a new template instance via new RestTemplate(myHttpRequestFactory)
.
Unfortunately, it looks somewhat non-trivial to create such a factory, even when you just want to set a single Authorization header, which is pretty frustrating considering what a common requirement that likely is, but at least it allows easy use if, for example, your Authorization header can be created from data contained in a Spring-Security Authorization
object, then you can create a factory that sets the outgoing AuthorizationHeader on every request by doing SecurityContextHolder.getContext().getAuthorization()
and then populating the header, with null checks as appropriate. Now all outbound rest calls made with that RestTemplate will have the correct Authorization header.
Without more emphasis placed on the HttpClientFactory mechanism, providing simple-to-overload base classes for common cases like adding a single header to requests, most of the nice convenience methods of RestTemplate
end up being a waste of time, since they can only rarely be used.
I'd like to see something simple like this made available
@Configuration
public class MyConfig {
@Bean
public RestTemplate getRestTemplate() {
return new RestTemplate(new AbstractHeaderRewritingHttpClientFactory() {
@Override
public HttpHeaders modifyHeaders(HttpHeaders headers) {
headers.addHeader("Authorization", computeAuthString());
return headers;
}
public String computeAuthString() {
// do something better than this, but you get the idea
return SecurityContextHolder.getContext().getAuthorization().getCredential();
}
});
}
}
At the moment, the interface of the available ClientHttpRequestFactory's are harder to interact with than that. Even better would be an abstract wrapper for existing factory implementations which makes them look like a simpler object like AbstractHeaderRewritingRequestFactory for the purposes of replacing just that one piece of functionality. Right now, they are very general purpose such that even writing those wrappers is a complex piece of research.
I am facing small trouble in returning a value from callback function in Node.js
This is not a "small trouble", it is actually impossible to "return" a value in the traditional sense from an asynchronous function.
Since you cannot "return the value" you must call the function that will need the value once you have it. @display_name already answered your question, but I just wanted to point out that the return in doCall is not returning the value in the traditional way. You could write doCall as follow:
function doCall(urlToCall, callback) {
urllib.request(urlToCall, { wd: 'nodejs' }, function (err, data, response) {
var statusCode = response.statusCode;
finalData = getResponseJson(statusCode, data.toString());
// call the function that needs the value
callback(finalData);
// we are done
return;
});
}
Line callback(finalData);
is what calls the function that needs the value that you got from the async function. But be aware that the return statement is used to indicate that the function ends here, but it does not mean that the value is returned to the caller (the caller already moved on.)
You could use:
git merge-file
Tip: https://www.kernel.org/pub/software/scm/git/docs/git-merge-file.html
If you have already defined your view in layout(xml) file and only want to change the weight pro grammatically, then then creating new LayoutParams overwrites other params defined in you xml file.
So first you should use "getLayoutParams" and then setLayoutParams
LinearLayout.LayoutParams params = (LinearLayout.LayoutParams) mButton.getLayoutParams();
params.weight = 4f;
mButton.setLayoutParams(params);
Inline Alternative:
<div>
<!-- Other content. -->
<a onclick='event.stopPropagation();' href="http://foo.com">I don't want #clickable to handle this click event.</a>
</div>
You need to use gdb's memory-display commands. The basic one is x
, for examine. There's an example on the linked-to page that uses
gdb> x/4xw $sp
to print "four words (w
) of memory above the stack pointer (here, $sp
) in hexadecimal (x
)". The quotation is slightly paraphrased.
You can simply use jQuery’s delay() method to set the delay time interval.
HTML code:
<div class="box"></div>
JQuery code:
$(document).ready(function(){
$(".show-box").click(function(){
$(this).text('loading...').delay(1000).queue(function() {
$(this).hide();
showBox();
$(this).dequeue();
});
});
});
You can see an example here: How to Call a Function After Some Time in jQuery
Why should I use it instead of optparse? Are their new features I should know about?
@Nicholas's answer covers this well, I think, but not the more "meta" question you start with:
Why has yet another command-line parsing module been created?
That's the dilemma number one when any useful module is added to the standard library: what do you do when a substantially better, but backwards-incompatible, way to provide the same kind of functionality emerges?
Either you stick with the old and admittedly surpassed way (typically when we're talking about complicated packages: asyncore vs twisted, tkinter vs wx or Qt, ...) or you end up with multiple incompatible ways to do the same thing (XML parsers, IMHO, are an even better example of this than command-line parsers -- but the email
package vs the myriad old ways to deal with similar issues isn't too far away either;-).
You may make threatening grumbles in the docs about the old ways being "deprecated", but (as long as you need to keep backwards compatibility) you can't really take them away without stopping large, important applications from moving to newer Python releases.
(Dilemma number two, not directly related to your question, is summarized in the old saying "the standard library is where good packages go to die"... with releases every year and a half or so, packages that aren't very, very stable, not needing releases any more often than that, can actually suffer substantially by being "frozen" in the standard library... but, that's really a different issue).
If there are multiple values for the same key, the following code will append those values to a list corresponding to their key,
d = dict()
for x,y in t:
if(d.has_key(y)):
d[y].append(x)
else:
d[y] = [x]
Here is my solution in TypeScript, following the idea that @Mizipzor suggested (using projection):
/**
* Determines whether a line segment defined by a start and end point intersects with a sphere defined by a center point and a radius
* @param a the start point of the line segment
* @param b the end point of the line segment
* @param c the center point of the sphere
* @param r the radius of the sphere
*/
export function lineSphereIntersects(
a: IPoint,
b: IPoint,
c: IPoint,
r: number
): boolean {
// find the three sides of the triangle formed by the three points
const ab: number = distance(a, b);
const ac: number = distance(a, c);
const bc: number = distance(b, c);
// check to see if either ends of the line segment are inside of the sphere
if (ac < r || bc < r) {
return true;
}
// find the angle between the line segment and the center of the sphere
const numerator: number = Math.pow(ac, 2) + Math.pow(ab, 2) - Math.pow(bc, 2);
const denominator: number = 2 * ac * ab;
const cab: number = Math.acos(numerator / denominator);
// find the distance from the center of the sphere and the line segment
const cd: number = Math.sin(cab) * ac;
// if the radius is at least as long as the distance between the center and the line
if (r >= cd) {
// find the distance between the line start and the point on the line closest to
// the center of the sphere
const ad: number = Math.cos(cab) * ac;
// intersection occurs when the point on the line closest to the sphere center is
// no further away than the end of the line
return ad <= ab;
}
return false;
}
export function distance(a: IPoint, b: IPoint): number {
return Math.sqrt(
Math.pow(b.z - a.z, 2) + Math.pow(b.y - a.y, 2) + Math.pow(b.x - a.x, 2)
);
}
export interface IPoint {
x: number;
y: number;
z: number;
}
The trim method should work great for you.
http://download.oracle.com/docs/cd/E17476_01/javase/1.4.2/docs/api/java/lang/String.html#trim()
Returns a copy of the string, with leading and trailing whitespace omitted. If this String object represents an empty character sequence, or the first and last characters of character sequence represented by this String object both have codes greater than '\u0020' (the space character), then a reference to this String object is returned.
Otherwise, if there is no character with a code greater than '\u0020' in the string, then a new String object representing an empty string is created and returned.
Otherwise, let k be the index of the first character in the string whose code is greater than '\u0020', and let m be the index of the last character in the string whose code is greater than '\u0020'. A new String object is created, representing the substring of this string that begins with the character at index k and ends with the character at index m-that is, the result of this.substring(k, m+1).
This method may be used to trim whitespace from the beginning and end of a string; in fact, it trims all ASCII control characters as well.
Returns: A copy of this string with leading and trailing white space removed, or this string if it has no leading or trailing white space.leading or trailing white space.
You could trim and then compare to an empty string or possibly check the length for 0.
I think the best way is:
data: "{'Ids':['2','2']}"
To read this values Ids[0], Ids[1].
In VBA we can not use if jj = 5 or 6 then
we must use if jj = 5 or jj = 6 then
maybe this:
If inputWks.Range("d9") > 0 And (inputWks.Range("d11") = "Restricted_Expenditure" Or inputWks.Range("d11") = "Unrestricted_Expenditure") Then
No, that's it. You might want to make sure you have all optional library headers installed too so you don't have to recompile it later. They are listed in the documentation I think.
Also, you can install it even in the standard path if you do make altinstall
. That way it won't override your current default "python".
You could do this
class x
{
private int _myInt;
public virtual int myInt { get { return _myInt; } set { _myInt = value; } }
}
class y : x
{
private int _myYInt;
public override int myInt { get { return _myYInt; } set { _myYInt = value; } }
}
virtual lets you get a property a body that does something and still lets sub-classes override it.
1: No difference. It is kept around to allow old S-code to continue to function. This is documented a "Note" in ?Math
2: Yes: But you already know it:
`^`(x,y)
#[1] 1024
In R the mathematical operators are really functions that the parser takes care of rearranging arguments and function names for you to simulate ordinary mathematical infix notation. Also documented at ?Math
.
Edit: Let me add that knowing how R handles infix operators (i.e. two argument functions) is very important in understanding the use of the foundational infix "[[" and "["-functions as (functional) second arguments to lapply
and sapply
:
> sapply( list( list(1,2,3), list(4,3,6) ), "[[", 1)
[1] 1 4
> firsts <- function(lis) sapply(lis, "[[", 1)
> firsts( list( list(1,2,3), list(4,3,6) ) )
[1] 1 4
One way that you can do it is creating a new object in the module instead of replacing it.
for example:
var testone = function () {
console.log('test one');
};
var testTwo = function () {
console.log('test two');
};
module.exports.testOne = testOne;
module.exports.testTwo = testTwo;
and to call
var test = require('path_to_file').testOne:
testOne();
try this:
timeout 5 ssh user@ip
timeout executes the ssh command (with args) and sends a SIGTERM if ssh doesn't return after 5 second. for more details about timeout, read this document: http://man7.org/linux/man-pages/man1/timeout.1.html
or you can use the param of ssh:
ssh -o ConnectTimeout=3 user@ip
This should work.

The background colors are there so you can see how this works. Copy this code to a file and open it in your browser. Try playing around with the CSS a bit and see what happens.
The width: inherit; height: inherit;
pulls the width and height from the parent element. This should be the default and is not truly necessary.
Try removing the h1 { ... }
CSS block and see what happens. You might notice the layout reacts in an odd way. This is because the h1
element is influencing the layout of its container. You could prevent this by declaring overflow: hidden;
on the container or the body.
I'd also suggest you do some reading on the CSS Box Model.
You can get clean and clear solutions by building the appropriate predicates as helper functions. In other words, use the Python set-builder notation the same way you would write the answer with regular mathematics set-notation.
The whole idea behind set comprehensions is to let us write and reason in code the same way we do mathematics by hand.
With an appropriate predicate in hand, problem 1 simplifies to:
low_primes = {x for x in range(1, 100) if is_prime(x)}
And problem 2 simplifies to:
low_prime_pairs = {(x, x+2) for x in range(1,100,2) if is_prime(x) and is_prime(x+2)}
Note how this code is a direct translation of the problem specification, "A Prime Pair is a pair of consecutive odd numbers that are both prime."
P.S. I'm trying to give you the correct problem solving technique without actually giving away the answer to the homework problem.
The Google Style Guide for HTML recommends omitting all optional tags.
That includes <html>
, <head>
, <body>
, <p>
and <li>
.
https://google.github.io/styleguide/htmlcssguide.html#Optional_Tags
For file size optimization and scannability purposes, consider omitting optional tags. The HTML5 specification defines what tags can be omitted.
(This approach may require a grace period to be established as a wider guideline as it’s significantly different from what web developers are typically taught. For consistency and simplicity reasons it’s best served omitting all optional tags, not just a selection.)

I had an issue similar to this and found out is was due to a default .Net framework setting
Sqlcommand.Timeout
The default is 30 seconds as sated in the above url by Microsoft, try setting this to a higher number of seconds or maybe -1 before opening the connection to see if this solves the issue.
It maybe a setting in your web.config or app.config files or on you applicaiton / web server config files.
First of all, the code you wrote isn't portable, even if you get it to work. Why use OS-specific functions when there is a perfectly platform-independent way of doing it? Here's a version that uses just a single header file and is portable to any platform that implements the C standard library.

EDIT: The glibc reference has this to say:
In general, you should stick with using streams rather than file descriptors, unless there is some specific operation you want to do that can only be done on a file descriptor. If you are a beginning programmer and aren't sure what functions to use, we suggest that you concentrate on the formatted input functions (see Formatted Input) and formatted output functions (see Formatted Output).
If you are concerned about portability of your programs to systems other than GNU, you should also be aware that file descriptors are not as portable as streams. You can expect any system running ISO C to support streams, but non-GNU systems may not support file descriptors at all, or may only implement a subset of the GNU functions that operate on file descriptors. Most of the file descriptor functions in the GNU library are included in the POSIX.1 standard, however.
My fix was to create Platform in configuration manager in visual studio, and set to x64
10 year old question but felt most of the answers were a bit convoluted or didn't quite work the way that was asked. Also the most upvoted answer here didn't provide any examples. Here's a simple class I made:
https://gist.github.com/Maxdw/d71afd11db2df4f1297ad3722d6392ec
Usage:
Trim.left("\joe\jill\", "\") == "joe\jill\"
Trim.left("jack\joe\jill\", "jack") == "\joe\jill\"
Trim.left("\\\\joe\\jill\\\\", "\") == "joe\\jill\\\\"
Define "much faster". Asymptotically they're about the same. The differences lie in how they make use of secondary storage. The Wikipedia articles on B-trees and B+trees look pretty trustworthy.
if($scope.test == null || $scope.test == undefined || $scope.test == "" || $scope.test.lenght == 0){
console.log("test is not defined");
}
else{
console.log("test is defined ",$scope.test);
}
Java 9 allows you to create an unmodifiable list with a single line of code using List.of
factory:
public class Main {
public static void main(String[] args) {
List<String> examples = List.of("one", "two", "three");
System.out.println(examples);
}
}
Output:
[one, two, three]
Normally the dot matches any character except newlines.
So if .*
isn't working, set the "dot matches newlines, too" option (or use (?s).*
).
If you're using JavaScript, which doesn't have a "dotall" option, try [\s\S]*
. This means "match any number of characters that are either whitespace or non-whitespace" - effectively "match any string".
Another option that only works for JavaScript (and is not recognized by any other regex flavor) is [^]*
which also matches any string. But [\s\S]*
seems to be more widely used, perhaps because it's more portable.

With the best TS support and many other useful features!
Use StringTokenizer to parse the string.
String s ="SALES:0,SALE_PRODUCTS:1,EXPENSES:2,EXPENSES_ITEMS:3";
Map<String, Integer> lMap=new HashMap<String, Integer>();
StringTokenizer st=new StringTokenizer(s, ",");
while(st.hasMoreTokens())
{
String [] array=st.nextToken().split(":");
lMap.put(array[0], Integer.valueOf(array[1]));
}
You could use cursor.lastrowid (see "Optional DB API Extensions"):
connection=sqlite3.connect(':memory:')
cursor=connection.cursor()
cursor.execute('''CREATE TABLE foo (id integer primary key autoincrement ,
username varchar(50),
password varchar(50))''')
cursor.execute('INSERT INTO foo (username,password) VALUES (?,?)',
('test','test'))
print(cursor.lastrowid)
# 1
If two people are inserting at the same time, as long as they are using different cursor
s, cursor.lastrowid
will return the id
for the last row that cursor
inserted:
cursor.execute('INSERT INTO foo (username,password) VALUES (?,?)',
('blah','blah'))
cursor2=connection.cursor()
cursor2.execute('INSERT INTO foo (username,password) VALUES (?,?)',
('blah','blah'))
print(cursor2.lastrowid)
# 3
print(cursor.lastrowid)
# 2
cursor.execute('INSERT INTO foo (id,username,password) VALUES (?,?,?)',
(100,'blah','blah'))
print(cursor.lastrowid)
# 100
Note that lastrowid
returns None
when you insert more than one row at a time with executemany
:
cursor.executemany('INSERT INTO foo (username,password) VALUES (?,?)',
(('baz','bar'),('bing','bop')))
print(cursor.lastrowid)
# None
The file you give is a shell script, not an awk program. So, try sh my.awk
.
If you want to use awk -f my.awk life.csv > life_out.cs
, then remove awk -F , '
and the last line from the file and add FS=","
in BEGIN
.
This is an old question, but if you wanted to break out of an if statement, you could do:
while 1:
if blah:
break
contentType
is the type of data you're sending, so application/json; charset=utf-8
is a common one, as is application/x-www-form-urlencoded; charset=UTF-8
, which is the default.
dataType
is what you're expecting back from the server: json
, html
, text
, etc. jQuery will use this to figure out how to populate the success function's parameter.
If you're posting something like:
{"name":"John Doe"}
and expecting back:
{"success":true}
Then you should have:
var data = {"name":"John Doe"}
$.ajax({
dataType : "json",
contentType: "application/json; charset=utf-8",
data : JSON.stringify(data),
success : function(result) {
alert(result.success); // result is an object which is created from the returned JSON
},
});
If you're expecting the following:
<div>SUCCESS!!!</div>
Then you should do:
var data = {"name":"John Doe"}
$.ajax({
dataType : "html",
contentType: "application/json; charset=utf-8",
data : JSON.stringify(data),
success : function(result) {
jQuery("#someContainer").html(result); // result is the HTML text
},
});
One more - if you want to post:
name=John&age=34
Then don't stringify
the data, and do:
var data = {"name":"John", "age": 34}
$.ajax({
dataType : "html",
contentType: "application/x-www-form-urlencoded; charset=UTF-8", // this is the default value, so it's optional
data : data,
success : function(result) {
jQuery("#someContainer").html(result); // result is the HTML text
},
});
change the MaxClients directive. it is now on 256.
I think you may have installed the version of mongodb for the wrong system distro.
Take a look at how to install mongodb for ubuntu and debian:
http://docs.mongodb.org/manual/tutorial/install-mongodb-on-debian/ http://docs.mongodb.org/manual/tutorial/install-mongodb-on-ubuntu/
I had a similar problem, and what happened was that I was installing the ubuntu packages in debian
If you want to avoid the mem cost of using the exec command, I believe you can do better with xargs. I think the following is a more efficient alternative to
find foo -type f ! -name '*Music*' -exec cp {} bar \; # new proc for each exec
find . -maxdepth 1 -name '*Music*' -prune -o -print0 | xargs -0 -i cp {} dest/
Ear files provide more options to configure the interaction with the application server.
For example: if the hibernate version of the application server is older than the one provided by your dependencies, you can add the following to ear-deployer-jboss-beans.xml for JBOSS to isolate classloaders and avoid conflicts:
<bean name="EARClassLoaderDeployer" class="org.jboss.deployment.EarClassLoaderDeployer">
<property name="isolated">true</property>
</bean>
or to src/main/application/META-INF/jboss-app.xml :
<?xml version="1.0"?>
<jboss-app>
<loader-repository>
loader=nameofyourear.ear
<loader-repository-config>java2ParentDelegation=false</loader-repository-config>
</loader-repository>
</jboss-app>
This will make sure that there is no classloader conflict between your application and the application server.
Normally the classloader mechanism works like this:
When a class loading request is presented to a class loader, it first asks its parent class loader to fulfill the request. The parent, in turn, asks its parent for the class until the request reaches the top of the hierarchy. If the class loader at the top of the hierarchy cannot fulfill the request, then the child class loader that called it is responsible for loading the class.
By isolating the classloaders, your ear classloader will not look in the parent (=JBoss / other AS classloader). As far is I know, this is not possible with war files.
Well, this question appears on top of search results, so I believe we need code example here. Here's the Python code:
import cv2
def apply_mask(frame, mask):
"""Apply binary mask to frame, return in-place masked image."""
return cv2.bitwise_and(frame, frame, mask=mask)
Mask and frame must be the same size, so pixels remain as-is where mask is 1
and are set to zero where mask pixel is 0
.
And for C++
it's a little bit different:
cv::Mat inFrame; // Original (non-empty) image
cv::Mat mask; // Original (non-empty) mask
// ...
cv::Mat outFrame; // Result output
inFrame.copyTo(outFrame, mask);
maybe something like this:
foreach (var keyvaluepair in dict)
{
if(Object.ReferenceEquals(keyvaluepair.Value, searchedObject))
{
//dict.Remove(keyvaluepair.Key);
break;
}
}
First I executed:
sudo chown -R $(whoami):admin /usr/local
Then:
cd $(brew --prefix) && git fetch origin && git reset --hard origin/master
The add
method that takes a String
and a Person
is calling a different add
method that takes a Position
. The one that takes Position
is inherited from the ArrayList
class.
Since your class Staff
extends ArrayList<Position>
, it automatically has the add(Position)
method. The new add(String, Person)
method is one that was written particularly for the Staff class.
_, err := os.Stat(file)
if err == nil {

} else if os.IsNotExist(err) {
log.Printf("file %s not exists", file)
} else {

}

If it's running all of the above from the command line that you're looking for, then I'd recommend HTTPie. It is a fantastic cURL alternative and is super easy and convenient to use (and customize).
Here's is its (succinct and precise) description from GitHub;
HTTPie (pronounced aych-tee-tee-pie) is a command line HTTP client. Its goal is to make CLI interaction with web services as human-friendly as possible.
It provides a simple http command that allows for sending arbitrary HTTP requests using a simple and natural syntax, and displays colorized output. HTTPie can be used for testing, debugging, and generally interacting with HTTP servers.

To respond to something Mehrdad said:
However, there might be cases where you still need arrays. When interfacing with low level code (i.e. assembly) or old libraries that require arrays, you might not be able to use vectors.
Not true at all. Vectors degrade nicely into arrays/pointers if you use:
vector<double> vector;
vector.push_back(42);
double *array = &(*vector.begin());
// pass the array to whatever low-level code you have
This works for all major STL implementations. In the next standard, it will be required to work (even though it does just fine today).
Simple and powerful way(dynamic validation)
place formats in array like "image/*"

var array=["video/mp4","image/png"];
upload.accept=array;

console.log(upload.value)

This won't win a code golf competition, and borrows from the previous answers - but clearly shows how the key is added, and how the join works. This creates 2 new data frames from lists, then adds the key to do the cartesian product on.
My use case was that I needed a list of all store IDs on for each week in my list. So, I created a list of all the weeks I wanted to have, then a list of all the store IDs I wanted to map them against.
The merge I chose left, but would be semantically the same as inner in this setup. You can see this in the documentation on merging, which states it does a Cartesian product if key combination appears more than once in both tables - which is what we set up.
days = pd.DataFrame({'date':list_of_days})
stores = pd.DataFrame({'store_id':list_of_stores})
stores['key'] = 0
days['key'] = 0
days_and_stores = days.merge(stores, how='left', on = 'key')
days_and_stores.drop('key',1, inplace=True)
Using map (halfdanrump's answer) is best for me, though haven't timed it...
But if you go for a dictionary, and if you have a big_dict:
so e.g.:
big_dict = {'a':1,'b':2,'c':3,................................................}
req = ['a','c','w']
{k:big_dict.get(k,None) for k in req )
# or
{k:big_dict[k] for k in req if k in big_dict)
Note that in the converse case, that the req is big, but my_dict is small, you should loop through my_dict instead.
In general, we are doing an intersection and the complexity of the problem is O(min(len(dict)),min(len(req))). Python's own implementation of intersection considers the size of the two sets, so it seems optimal. Also, being in c and part of the core library, is probably faster than most not optimized python statements. Therefore, a solution that I would consider is:
dict = {'a':1,'b':2,'c':3,................................................}
req = ['a','c','w',...................]
{k:dic[k] for k in set(req).intersection(dict.keys())}
It moves the critical operation inside python's c code and will work for all cases.
Dynamically adding directives on angularjs has two styles:
it's simple. And u can use in "link" or "compile".
var newElement = $compile( "<div my-diretive='n'></div>" )( $scope );
$element.parent().append( newElement );
It's hard, and make me headache within two days.
Using "$compile" will raise critical recursive error!! Maybe it should ignore the current directive when re-compiling element.
$element.$set("myDirective", "expression");
var newElement = $compile( $element )( $scope ); // critical recursive error.
var newElement = angular.copy(element); // the same error too.
$element.replaceWith( newElement );
So, I have to find a way to call the directive "link" function. It's very hard to get the useful methods which are hidden deeply inside closures.
compile: (tElement, tAttrs, transclude) ->
links = []
myDirectiveLink = $injector.get('myDirective'+'Directive')[0] #this is the way
links.push myDirectiveLink
myAnotherDirectiveLink = ($scope, $element, attrs) ->
#....
links.push myAnotherDirectiveLink
return (scope, elm, attrs, ctrl) ->
for link in links
link(scope, elm, attrs, ctrl)
Now, It's work well.
Let's start with a qualitative description of what we want to do (much of this is said in Ben Straub's answer). We've made some number of commits, five of which changed a given file, and we want to revert the file to one of the previous versions. First of all, git doesn't keep version numbers for individual files. It just tracks content - a commit is essentially a snapshot of the work tree, along with some metadata (e.g. commit message). So, we have to know which commit has the version of the file we want. Once we know that, we'll need to make a new commit reverting the file to that state. (We can't just muck around with history, because we've already pushed this content, and editing history messes with everyone else.)
So let's start with finding the right commit. You can see the commits which have made modifications to given file(s) very easily:
git log path/to/file
If your commit messages aren't good enough, and you need to see what was done to the file in each commit, use the -p/--patch
option:
git log -p path/to/file
Or, if you prefer the graphical view of gitk
gitk path/to/file
You can also do this once you've started gitk through the view menu; one of the options for a view is a list of paths to include.
Either way, you'll be able to find the SHA1 (hash) of the commit with the version of the file you want. Now, all you have to do is this:
# get the version of the file from the given commit
git checkout <commit> path/to/file
# and commit this modification
git commit
(The checkout command first reads the file into the index, then copies it into the work tree, so there's no need to use git add
to add it to the index in preparation for committing.)
If your file may not have a simple history (e.g. renames and copies), see VonC's excellent comment. git
can be directed to search more carefully for such things, at the expense of speed. If you're confident the history's simple, you needn't bother.

Here is the answer with some explanation.
st = "Hey, you - what are you doing here!?"
# replace all the non alpha-numeric with space and then join.
new_string = ''.join([x.replace(x, ' ') if not x.isalnum() else x for x in st])
# output of new_string
'Hey you what are you doing here '
# str.split() will remove all the empty string if separator is not provided
new_list = new_string.split()
# output of new_list
['Hey', 'you', 'what', 'are', 'you', 'doing', 'here']
# we can join it to get a complete string without any non alpha-numeric character
' '.join(new_list)
# output
'Hey you what are you doing'
or in one line, we can do like this:
(''.join([x.replace(x, ' ') if not x.isalnum() else x for x in st])).split()
# output
['Hey', 'you', 'what', 'are', 'you', 'doing', 'here']
updated answer
Standard C doesn't define binary constants. There's a GNU (I believe) extension though (among popular compilers, clang adapts it as well): the 0b
prefix:
int foo = 0b1010;
If you want to stick with standard C, then there's an option: you can combine a macro and a function to create an almost readable "binary constant" feature:
#define B(x) S_to_binary_(#x)
static inline unsigned long long S_to_binary_(const char *s)
{
unsigned long long i = 0;
while (*s) {
i <<= 1;
i += *s++ - '0';
}
return i;
}
And then you can use it like this:
int foo = B(1010);
If you turn on heavy compiler optimizations, the compiler will most likely eliminate the function call completely (constant folding) or will at least inline it, so this won't even be a performance issue.
Proof:
The following code:
#include <stdio.h>
#include <stdlib.h>
#include <limits.h>
#include <string.h>
#define B(x) S_to_binary_(#x)
static inline unsigned long long S_to_binary_(const char *s)
{
unsigned long long i = 0;
while (*s) {
i <<= 1;
i += *s++ - '0';
}
return i;
}
int main()
{
int foo = B(001100101);
printf("%d\n", foo);
return 0;
}
has been compiled using clang -o baz.S baz.c -Wall -O3 -S
, and it produced the following assembly:
.section __TEXT,__text,regular,pure_instructions
.globl _main
.align 4, 0x90
_main: ## @main
.cfi_startproc
## BB#0:
pushq %rbp
Ltmp2:
.cfi_def_cfa_offset 16
Ltmp3:
.cfi_offset %rbp, -16
movq %rsp, %rbp
Ltmp4:
.cfi_def_cfa_register %rbp
leaq L_.str1(%rip), %rdi
movl $101, %esi ## <= This line!
xorb %al, %al
callq _printf
xorl %eax, %eax
popq %rbp
ret
.cfi_endproc
.section __TEXT,__cstring,cstring_literals
L_.str1: ## @.str1
.asciz "%d\n"
.subsections_via_symbols
So clang
completely eliminated the call to the function, and replaced its return value with 101
. Neat, huh?
The variables/parameters within the class
definition requires { get; set; }
I was using like a variable declaration (stupid of me, because it was working for other scenarios) without
{ get; set; }
Because of which, whatever I send from the JavaScript, it was not being received in the Action method. It was always getting null or empty model.
Once the {get; set;} is added, it worked like charm.
I hope it helps someone who is coming from VB6 style of programming line.
If you'd like to track only failed logins, you can use the SQL Server Audit feature (available in SQL Server 2008 and above). You will need to add the SQL server instance you want to audit, and check the failed login operation to audit.
Note: tracking failed logins via SQL Server Audit has its disadvantages. For example - it doesn't provide the names of client applications used.
If you want to audit a client application name along with each failed login, you can use an Extended Events session.
To get you started, I recommend reading this article: http://www.sqlshack.com/using-extended-events-review-sql-server-failed-logins/
Here is an example straight from PHP.net
$a = array(
"one" => 1,
"two" => 2,
"three" => 3,
"seventeen" => 17
);
foreach ($a as $k => $v) {
echo "\$a[$k] => $v.\n";
}
in the foreach you can do a comparison of each key to something that you are looking for
To compare floating point, double or float types, use the specific method of CSharp:
if (double1.CompareTo(double2) > 0)
{
// double1 is greater than double2
}
if (double1.CompareTo(double2) < 0)
{
// double1 is less than double2
}
if (double1.CompareTo(double2) == 0)
{
// double1 equals double2
}

The way that Magento themes handle actual url's is as such (in view partials - phtml files):
echo $this->getSkinUrl('images/logo.png');
If you need the actual base path on disk to the image directory use:
echo Mage::getBaseDir('skin');
Some more base directory types are available in this great blog post:
Try this:
Now you can extend %base-class in any of your classes (e.g. .my-class).
%base-class {
width: 80%;
margin-left: 10%;
margin-right: 10%;
}
.my-base-class {
@extend %base-class;
}
.my-class {
@extend %base-class;
margin-bottom: 40px;
}
C doesn't have exceptions.

In my case was that I have enable "Show All Files". Visual Studio 2017
another solution:
add src/myproject

Then import "mylib"

You mentioned a signed angle (-90). In many applications angles may have signs (positive and negative, see http://en.wikipedia.org/wiki/Angle). If the points are (say) P2(1,0), P1(0,0), P3(0,1) then the angle P3-P1-P2 is conventionally positive (PI/2) whereas the angle P2-P1-P3 is negative. Using the lengths of the sides will not distinguish between + and - so if this matters you will need to use vectors or a function such as Math.atan2(a, b).
Angles can also extend beyond 2*PI and while this is not relevant to the current question it was sufficiently important that I wrote my own Angle class (also to make sure that degrees and radians did not get mixed up). The questions as to whether angle1 is less than angle2 depends critically on how angles are defined. It may also be important to decide whether a line (-1,0)(0,0)(1,0) is represented as Math.PI or -Math.PI
// Swift 2
override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {
let orientation: UIInterfaceOrientationMask =
[UIInterfaceOrientationMask.Portrait, UIInterfaceOrientationMask.PortraitUpsideDown]
return orientation
}
I fell into this issue because my Activity was called MainActivityMVVM and the Binding was converted into MainActivityMvvmBinding
instead of MainActivityMVVMBinding
. After digging into the generated classes I found the issue.
I have created function to disable previous date, disable flexible weekend days (Like Saturday, Sunday)
We are using beforeShowDay method of jQuery UI datepicker plugin.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
var NotBeforeToday = function(date) {_x000D_
var now = new Date(); //this gets the current date and time_x000D_
if (date.getFullYear() == now.getFullYear() && date.getMonth() == now.getMonth() && date.getDate() >= now.getDate() && (date.getDay() > 0 && date.getDay() < 6) )_x000D_
return [true,""];_x000D_
if (date.getFullYear() >= now.getFullYear() && date.getMonth() > now.getMonth() && (date.getDay() > 0 && date.getDay() < 6))_x000D_
return [true,""];_x000D_
if (date.getFullYear() > now.getFullYear() && (date.getDay() > 0 && date.getDay() < 6))_x000D_
return [true,""];_x000D_
return [false,""];_x000D_
}_x000D_
_x000D_
_x000D_
jQuery("#datepicker").datepicker({_x000D_
beforeShowDay: NotBeforeToday_x000D_
});
_x000D_
Here today's date is 15th Sept. I have disabled Saturday and Sunday.
From an answer to Force a browser to save file as after clicking link:
<a href="path/to/file" download>Click here to download</a>
I would suggest 3 things:
The last one worked for me.
%s%d%s%d\n is a format string. It is used to specify how the information is formatted on an output. here the format string is supposed to print string followed by a digit followed by a string and then again a digit. The last symbol \n represents carriage return which marks the end of a line. In C, strings cannot be concatenated by + or , although you can combine different outputs on a single line by using the appropriate format strings (the use of format strings is to format output info.).
You can turn on your PHP errors with error_reporting
:
error_reporting(E_ALL);
ini_set('display_errors', 'on');
Edit: It's possible that even after putting this, errors still don't show up. This can be caused if there is a fatal error in the script. From PHP Runtime Configuration:
Although display_errors may be set at runtime (with ini_set()), it won't have any affect if the script has fatal errors. This is because the desired runtime action does not get executed.
You should set display_errors = 1
in your php.ini
file and restart the server.
If you can't access the file and your os is any linux distro or mac os x then either of these commands should work:
sudo nano .bashrc
chmod 777 .bashrc
it is worthless
Something like this should work unless I'm missing the point:
import json
import urllib2
json.load(urllib2.urlopen("url"))
If you're happy to use the Microsoft Reactive Extensions, then this can work nicely:
public class Foo
{
public delegate void MyEventHandler(object source, MessageEventArgs args);
public event MyEventHandler _event;
public string ReadLine()
{
return Observable
.FromEventPattern<MyEventHandler, MessageEventArgs>(
h => this._event += h,
h => this._event -= h)
.Select(ep => ep.EventArgs.Message)
.First();
}
public void SendLine(string message)
{
_event(this, new MessageEventArgs() { Message = message });
}
}
public class MessageEventArgs : EventArgs
{
public string Message;
}
I can use it like this:
var foo = new Foo();
ThreadPoolScheduler.Instance
.Schedule(
TimeSpan.FromSeconds(5.0),
() => foo.SendLine("Bar!"));
var resp = foo.ReadLine();
Console.WriteLine(resp);
I needed to call the SendLine
message on a different thread to avoid locking, but this code shows that it works as expected.
The value you have passed as the file descriptor is not valid. It is either negative or does not represent a currently open file or socket.
So you have either closed the socket before calling write()
or you have corrupted the value of 'sockfd' somewhere in your code.
It would be useful to trace all calls to close()
, and the value of 'sockfd' prior to the write()
calls.
Your technique of only printing error messages in debug mode seems to me complete madness, and in any case calling another function between a system call and perror()
is invalid, as it may disturb the value of errno
. Indeed it may have done so in this case, and the real underlying error may be different.
You can use the step attribute to the input type number:
<input type="number" id="totalAmt" step="0.1"></input>
step="any"
will allow any decimal.
step="1"
will allow no decimal.
step="0.5"
will allow 0.5; 1; 1.5; ...
step="0.1"
will allow 0.1; 0.2; 0.3; 0.4; ...
For me,
I did not install that nib in required target.
Step 1: Click on your nib in Project Navigator (i.e. In First left tab)
Step 2: Go to File Inspector (i.e. In First right tab)
Step 3: Go to Target membership and tick on target in which you want to use your nib.
If you want a version that raises an error:
"string to search".index("needle")
If you want a version that returns -1:
"string to search".find("needle")
This is more efficient than the 'in' syntax
REPEAT
...
UNTIL cond
Is equivalent to
while True:
...
if cond:
break
If your click handler is successfully called then this should work:
$('#results').on('click', '.item', function () {
var NestId = $(this).data('id');
var url = "/Artists/Details?NestId=" + NestId;
window.location.href = url;
})
EDIT: In this particular case given that the action method parameter is a string which is nullable, then if NestId == null
, won't cause any exception at all, given that the ModelBinder won't complain about it.
