Ctrl + / works for me in Chrome browser in MS Windows. On a Mac, use Cmd + / (thanks Anton K).
Please note, if /
did not work out of the box, try pressing the /

In addition to the Wikipedia Cyclic redundancy check and Computation of CRC articles, I found a paper entitled Reversing CRC - Theory and Practice* to be a good reference.
There are essentially three approaches for computing a CRC: an algebraic approach, a bit-oriented approach, and a table-driven approach. In Reversing CRC - Theory and Practice*, each of these three algorithms/approaches is explained in theory accompanied in the APPENDIX by an implementation for the CRC32 in the C programming language.

.nil?
can be used on any object and is true if the object is nil.
.empty?
can be used on strings, arrays and hashes and returns true if:
Running .empty?
on something that is nil will throw a NoMethodError
.
That is where .blank?
comes in. It is implemented by Rails and will operate on any object as well as work like .empty?
on strings, arrays and hashes.
nil.blank? == true
false.blank? == true
[].blank? == true
{}.blank? == true
"".blank? == true
5.blank? == false
0.blank? == false
.blank?
also evaluates true on strings which are non-empty but contain only whitespace:
" ".blank? == true
" ".empty? == false
Rails also provides .present?
, which returns the negation of .blank?
.
Array gotcha: blank?
will return false
even if all elements of an array are blank. To determine blankness in this case, use all?
with blank?
, for example:
[ nil, '' ].blank? == false
[ nil, '' ].all? &:blank? == true
You can find last character using php many ways like substr() and mb_substr().
If you’re using multibyte character encodings like UTF-8, use mb_substr instead of substr
Here i can show you both example:
<?php
echo substr("testers", -1);
echo mb_substr("testers", -1);
?>
You can use below function for relative path as absolute path is not a good idea to add in script
Import
import sys, os
Use code as below :
ROOT_DIR = os.path.dirname(os.path.abspath(__file__))
screenshotpath = os.path.join(os.path.sep, ROOT_DIR,'Screenshots'+ os.sep)
driver.get_screenshot_as_file(screenshotpath+"testPngFunction.png")
make sure you create the folder where the .py file is present.
os.path.join
also prevent you to run your script in cross-platform like: UNIX and windows. It will generate path separator as per OS at runtime. os.sep
is similar like File.separtor
in java
simply add as many properties as you need to the data object.
$.ajax({
type: "POST",
url: "popup.aspx/GetJewellerAssets",
contentType: "application/json; charset=utf-8",
data: {jewellerId: filter , foo: "bar", other: "otherValue"},
dataType: "json",
success: AjaxSucceeded,
error: AjaxFailed
});
You are experiencing this issue for two reasons.
When performing a join in JPQL you must ensure that an underlying association between the entities attempting to be joined exists. In your example, you are missing an association between the User and Area entities. In order to create this association we must add an Area field within the User class and establish the appropriate JPA Mapping. I have attached the source for User below. (Please note I moved the mappings to the fields)
User.java
@Entity
@Table(name="user")
public class User {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="iduser")
private Long idUser;
@Column(name="user_name")
private String userName;
@OneToOne()
@JoinColumn(name="idarea")
private Area area;
public Long getIdUser() {
return idUser;
}
public void setIdUser(Long idUser) {
this.idUser = idUser;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public Area getArea() {
return area;
}
public void setArea(Area area) {
this.area = area;
}
}
Once this relationship is established you can reference the area object in your @Query declaration. The query specified in your @Query annotation must follow proper syntax, which means you should omit the on clause. See the following:
@Query("select u.userName from User u inner join u.area ar where ar.idArea = :idArea")
While looking over your question I also made the relationship between the User and Area entities bidirectional. Here is the source for the Area entity to establish the bidirectional relationship.
Area.java
@Entity
@Table(name = "area")
public class Area {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name="idarea")
private Long idArea;
@Column(name="area_name")
private String areaName;
@OneToOne(fetch=FetchType.LAZY, mappedBy="area")
private User user;
public Long getIdArea() {
return idArea;
}
public void setIdArea(Long idArea) {
this.idArea = idArea;
}
public String getAreaName() {
return areaName;
}
public void setAreaName(String areaName) {
this.areaName = areaName;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
if you want to wrap the data in td then you can use the below code
td{
width:60%;
word-break: break-word;
}
Correct way to exclude default logging, and configure log4j for logging.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
<exclusions>
<exclusion>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-logging</artifactId>
</exclusion>
</exclusions>
</dependency>
Refer Spring Logging - How To.
In gradle, I needed to do this with several other dependencies:
configurations {
all*.exclude module : 'spring-boot-starter-logging'
all*.exclude module : 'logback-classic'
}
you can make it using js file and ajax call. while validating data using js file we can read the text of selected dropdown
$("#dropdownid").val(); for value
$("#dropdownid").text(); for selected value
catch these into two variables and take it as inputs to ajax call for a php file
$.ajax
({
url:"callingphpfile.php",//url of fetching php
method:"POST", //type
data:"val1="+value+"&val2="+selectedtext,
success:function(data) //return the data
{
}
and in php you can get it as
if (isset($_POST["val1"])) {
$val1= $_POST["val1"] ;
}
if (isset($_POST["val2"])) {
$selectedtext= $_POST["val1"];
}
//Just add
RewriteBase /
//after
RewriteEngine On
//and you are done....
//so it should be
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [QSA,L]
Remember when you used to sum, for example 2 & 3, in your old calculator and every time you hit the =
you see 3 added to the total, the +=
does similar job. Example:
>>> orange = 2
>>> orange += 3
>>> print(orange)
5
>>> orange +=3
>>> print(orange)
8
@ingsaurabh's answer is the way to go if you are using an onClick even. However, if you are using an onTouch event, you can select the different backgrounds (still the same as @ingsaurabh's example) by using view.setPressed()
.

Debian/Ubuntu handles this with a cronjob defined in /etc/cron.d/php5
# /etc/cron.d/php5: crontab fragment for php5
# This purges session files older than X, where X is defined in seconds
# as the largest value of session.gc_maxlifetime from all your php.ini
# files, or 24 minutes if not defined. See /usr/lib/php5/maxlifetime
# Look for and purge old sessions every 30 minutes
09,39 * * * * root [ -d /var/lib/php5 ] && find /var/lib/php5/ -type f -cmin +$(/usr/lib/php5/maxlifetime) -print0 | xargs -r -0 rm
The maxlifetime script simply returns the number of minutes a session should be kept alive by checking php.ini, it looks like this
#!/bin/sh -e
max=1440
for ini in /etc/php5/*/php.ini; do
cur=$(sed -n -e 's/^[[:space:]]*session.gc_maxlifetime[[:space:]]*=[[:space:]]*\([0-9]\+\).*$/\1/p' $ini 2>/dev/null || true);
[ -z "$cur" ] && cur=0
[ "$cur" -gt "$max" ] && max=$cur
done
echo $(($max/60))
exit 0
You can use $_SERVER['HTTP_REFERER']
this will give you whole URL for example:
suppose you want to get url of site name www.example.com
then $_SERVER['HTTP_REFERER']
will give you https://www.example.com

Follow these steps to run your application on the device connected.
1. Change directories to the root of your Android project and execute:
ant debug
2. Make sure the Android SDK platform-tools/
directory is included in your PATH
environment variable, then execute: adb install bin/<*your app name*>-debug.apk
On your device, locate <*your app name*>
and open it.
Refer Running App
If you change .bash_profile, it only applies to new Terminal sessions.
To apply it to an existing session, run source ~/.bash_profile
. You can run any Bash script this way - think of executing source
as the same as typing commands in the Terminal window (from the specified script).
More info: How to reload .bash_profile from the command line?
Bonus: You can make environment variables available to OSX applications - not just the current Bash session but apps like Visual Studio Code or IntelliJ - using launchctl setenv GOPATH "${GOPATH:-}"

The .map
files are for js
and css
(and now ts
too) files that have been minified. They are called SourceMaps. When you minify a file, like the angular.js file, it takes thousands of lines of pretty code and turns it into only a few lines of ugly code. Hopefully, when you are shipping your code to production, you are using the minified code instead of the full, unminified version. When your app is in production, and has an error, the sourcemap will help take your ugly file, and will allow you to see the original version of the code. If you didn't have the sourcemap, then any error would seem cryptic at best.
Same for CSS files. Once you take a SASS or LESS file and compile it to CSS, it looks nothing like its original form. If you enable sourcemaps, then you can see the original state of the file, instead of the modified state.
So, to answer you questions in order:
I hope this makes sense.
I think this is the easiest way for multy selection/update/insert/delete. You can run as many update/insert/delete as u want after select (you have to make a select first(a dummy if needed)) with executeUpdate(str) (just use new int(count1,count2,...)) and if u need a new selection close 'statement' and 'connection' and make new for next select. Like example:
String str1 = "select * from users";
String str9 = "INSERT INTO `port`(device_id, potition, port_type, di_p_pt) VALUE ('"+value1+"', '"+value2+"', '"+value3+"', '"+value4+"')";
String str2 = "Select port_id from port where device_id = '"+value1+"' and potition = '"+value2+"' and port_type = '"+value3+"' ";
try{
Class.forName("com.mysql.jdbc.Driver").newInstance();
theConnection=(Connection) DriverManager.getConnection(dbURL,dbuser,dbpassword);
theStatement = theConnection.prepareStatement(str1);
ResultSet theResult = theStatement.executeQuery();
int count8 = theStatement.executeUpdate(str9);
theStatement.close();
theConnection.close();
theConnection=DriverManager.getConnection(dbURL,dbuser,dbpassword);
theStatement = theConnection.prepareStatement(str2);
theResult = theStatement.executeQuery();
ArrayList<Port> portList = new ArrayList<Port>();
while (theResult.next()) {
Port port = new Port();
port.setPort_id(theResult.getInt("port_id"));
portList.add(port);
}
I hope it helps
$('#dbType').change(function(){
var selection = $(this).val();

Let me expand a bit on a VonC's very comprehensive answer:
First, if I remember it correctly, the fact that Git by default doesn't create merge commits in the fast-forward case has come from considering single-branch "equal repositories", where mutual pull is used to sync those two repositories (a workflow you can find as first example in most user's documentation, including "The Git User's Manual" and "Version Control by Example"). In this case you don't use pull to merge fully realized branch, you use it to keep up with other work. You don't want to have ephemeral and unimportant fact when you happen to do a sync saved and stored in repository, saved for the future.
Note that usefulness of feature branches and of having multiple branches in single repository came only later, with more widespread usage of VCS with good merging support, and with trying various merge-based workflows. That is why for example Mercurial originally supported only one branch per repository (plus anonymous tips for tracking remote branches), as seen in older revisions of "Mercurial: The Definitive Guide".
Second, when following best practices of using feature branches, namely that feature branches should all start from stable version (usually from last release), to be able to cherry-pick and select which features to include by selecting which feature branches to merge, you are usually not in fast-forward situation... which makes this issue moot. You need to worry about creating a true merge and not fast-forward when merging a very first branch (assuming that you don't put single-commit changes directly on 'master'); all other later merges are of course in non fast-forward situation.
HTH
You'll need to serialize to something: that is, pick binary, or xml (for default serializers) or write custom serialization code to serialize to some other text form.
Once you've picked that, your serialization will (normally) call a Stream that is writing to some kind of file.
So, with your code, if I were using XML Serialization:
var path = @"C:\Test\myserializationtest.xml";
using(FileStream fs = new FileStream(path, FileMode.Create))
{
XmlSerializer xSer = new XmlSerializer(typeof(SomeClass));
xSer.Serialize(fs, serializableObject);
}
Then, to deserialize:
using(FileStream fs = new FileStream(path, FileMode.Open)) //double check that...
{
XmlSerializer _xSer = new XmlSerializer(typeof(SomeClass));
var myObject = _xSer.Deserialize(fs);
}
NOTE: This code hasn't been compiled, let alone run- there may be some errors. Also, this assumes completely out-of-the-box serialization/deserialization. If you need custom behavior, you'll need to do additional work.
As others pointed out, it is not good practice to initialize data on views. Initializing data on Controllers, however, is recommended. (see http://docs.angularjs.org/guide/controller)
So you can write
<input name="card[description]" ng-model="card.description">
and
$scope.card = { description: 'Visa-4242' };
$http.get('/getCardInfo.php', function(data) {
$scope.card = data;
});
This way the views do not contain data, and the controller initializes the value while the real values are being loaded.
How about .delay()
?
$("#test").animate({"top":"-=80px"},1500)
.delay(1000)
.animate({"opacity":"0"},500);
You can't call a PHP function with Javascript, in the same way you can't call arbitrary PHP functions when you load a page (just think of the security implications).
If you need to wrap your code in a function for whatever reason, why don't you either put a function call under the function definition, eg:
function test() {
// function code
}
test();
Or, use a PHP include:
include 'functions.php'; // functions.php has the test function
test();
I can't comment on mcaleaa's answer, hence I post this here. The "diff" variable should be on small case. Here is an example.
[root@test ~]# date1=$(date +"%s"); date
Wed Feb 21 23:00:20 MYT 2018
[root@test ~]#
[root@test ~]# date2=$(date +"%s"); date
Wed Feb 21 23:00:33 MYT 2018
[root@test ~]#
[root@test ~]# diff=$(($date2-$date1))
[root@test ~]#
Previous variable was declared on lower case. This is what happened when upper case is used.
[root@test ~]# echo "Duration: $(($DIFF / 3600 )) hours $((($DIFF % 3600) / 60)) minutes $(($DIFF % 60)) seconds"
-bash: / 3600 : syntax error: operand expected (error token is "/ 3600 ")
[root@test ~]#
So, quick fix would be like this
[root@test ~]# echo "Duration: $(($diff / 3600 )) hours $((($diff % 3600) / 60)) minutes $(($diff % 60)) seconds"
Duration: 0 hours 0 minutes 13 seconds
[root@test ~]#
In css you can't set table-cells max height, and if you white-space nowrap then you can't break it with max width, so the solution is javascript working in all browsers.
So, this can work for you.
For Limiting max-height of all cells or rows in table with Javascript:
This script is good for horizontal overflow tables.
This script increase the table width 300px each time, maximum 4000px until rows shrinks to max-height(160px) , and you can also edit numbers as your need.
var i = 0, row, table = document.getElementsByTagName('table')[0], j = table.offsetWidth;
while (row = table.rows[i++]) {
while (row.offsetHeight > 160 && j < 4000) {
j += 300;
table.style.width = j + 'px';
}
}

First, you need to configure your computer to get a static IP from your router. Instructions for how to do this can be found: here
For example, let's say you picked the IP address 192.168.1.102. After the above step is completed, you should be able to get to the website on your local machine by going to both http://localhost and http://192.168.1.102, since your computer will now always have that IP address on your network.
If you look up your IP address (such as http://www.ip-adress.com/), the IP you see is actually the IP of your router. When your friend accesses your website, you'll give him this IP. However, you need to tell your router that when it gets a request for a webpage, forward that request to your server. This is done through port forwarding.
Two examples of how to do this can be found here and here, although the exact screens you see will vary depending on the manufacturer of your router (Google for exact instructions, if needed).
For the Linksys router I have, I enter http://192.168.1.1/, enter my username/password, Applications & Gaming tab > Port Range Forward. Enter the application name (whatever you want to call it), start port (80), end port (80), protocol (TCP), ip address (using the above example, you would enter 192.168.1.102, which is the static IP you assigned your server), and be sure to check to enable the forwarding. Restart your router and the changes should take effect.
Having done all that, your friend should now be able to access your webpage by going to his web browser on his machine and entering http://IP.address.of.your.computer (the same one you see when you go here ).
As mentioned earlier, the IP address assigned to you by your ISP will eventually change whether you sign offline or not. I strongly recommend using DynDns, which is absolutely free. You can choose a hostname at their domain (such as cuga.kicks-ass.net) and your friend can then always access your website by simply going to http://cuga.kicks-ass.net in his browser. Here is their site again: DynDns
I hope this helps.
By definition, git reset --hard
will throw away uncommitted changes without any way for Git to recover them (your backup system may help, but not Git).
Actually, there are very few cases where git reset --hard
is a good idea. In most cases, there's a safer command to do the same thing:
If you want to throw away your uncommitted changes, then use git stash
. It will keep a backup of these changes, which will expire after some time if you run git gc
. If you're 99.9% sure you'll never need these changes back, then git stash
is still your friend for the 0.1% case. If you're 100% sure, then git stash
is still your friend because these 100% have a measurement error ;-).
If you want to move your HEAD
and the tip of the current branch in history, then git reset --keep
is your friend. It will do the same thing as git reset --hard
, but will not discard your local changes.
If you want to do both, then git stash && git reset --keep
is your friend.
Teach your fingers not to use git reset --hard
, it will pay back one day.
I use this command:
netstat -tulpn | grep LISTEN
You can have a clean output that shows process id and ports that's listening on
You're missing the actual pipe.
{{ myData | date:'fullDate' }}
Multiple parameters can be separated by a colon (:).
{{ myData | myPipe:'arg1':'arg2':'arg3' }}
Also you can chain pipes, like so:
{{ myData | date:'fullDate' | myPipe:'arg1':'arg2':'arg3' }}
Expanding on what Mark Elliot said earlier, the easiest way to get the size of a 2D array given that each array in the array of arrays is of the same size is:
array.length * array[0].length
The following works in MVC5:
document.getElementById('theID').value = 'new value';
I had the same problem under Windows and could solve it by running cmd.exe as administrator (right-click in start menu, then "Run as administrator).
You can use this:
String abc = "kushalhs , mayurvm , narendrabz ,";
String a = abc.substring(0, abc.lastIndexOf(","));
Joining the party late, but just as a complement, I ran into some problems with Seaborn not so long ago, because CoLab installed a version with !pip that wasn't updated. In my specific case, I couldn't use Scatterplot, for example. The answer to this is below:
To install the module, all you need is:
!pip install seaborn
To upgrade it to the most updated version:
!pip install --upgrade seaborn
If you want to install a specific version
!pip install seaborn==0.9.0
I believe all the rules common to pip apply normally, so that pretty much should work.
The string literals are const char *
s.
And your use of parenthesis is odd. You probably mean
const char *a[2] = {"blah", "hmm"};
which declares an array of two pointers to constant characters, and initializes them to point at two hardcoded string constants.
puts "string".split('').map(&:ord).to_s
You could convert it to a string instead of printing the list directly:
print(", ".join(LIST))
If the elements in the list aren't strings, you can convert them to string using either repr
(if you want quotes around strings) or str
(if you don't), like so:
LIST = [1, "foo", 3.5, { "hello": "bye" }]
print( ", ".join( repr(e) for e in LIST ) )
Which gives the output:
1, 'foo', 3.5, {'hello': 'bye'}
An XSD file is an XML Schema Definition and it is used to provide a standard method of checking that a given XML document conforms to what you expect.
DateTime.TryParse
This I believe is faster and it means you dont have to use ugly try/catches :)
e.g
DateTime temp;
if(DateTime.TryParse(startDateTextBox.Text, out temp))
{
// Yay :)
}
else
{
// Aww.. :(
}
If your backgrounds are in the drawable folder right now try moving the images from drawable to drawable-nodpi folder in your project. This worked for me, seems that else the images are rescaled by them self..
If none of the above seem to help, in my environment was broken from a system upgrade and I could not upgrade pip. While it won't give you an accurate list you can get an idea of which libraries were installed simply by looking inside your env>lib>python(version here)>site-packages> . Here you will get a good indication of modules installed.
For me it is often useful being able to set different log levels for each TAG.
I am using this very simple wrapper class:
public class Log2 {
public enum LogLevels {
VERBOSE(android.util.Log.VERBOSE), DEBUG(android.util.Log.DEBUG), INFO(android.util.Log.INFO), WARN(
android.util.Log.WARN), ERROR(android.util.Log.ERROR);
int level;
private LogLevels(int logLevel) {
level = logLevel;
}
public int getLevel() {
return level;
}
};
static private HashMap<String, Integer> logLevels = new HashMap<String, Integer>();
public static void setLogLevel(String tag, LogLevels level) {
logLevels.put(tag, level.getLevel());
}
public static int v(String tag, String msg) {
return Log2.v(tag, msg, null);
}
public static int v(String tag, String msg, Throwable tr) {
if (logLevels.containsKey(tag)) {
if (logLevels.get(tag) > android.util.Log.VERBOSE) {
return -1;
}
}
return Log.v(tag, msg, tr);
}
public static int d(String tag, String msg) {
return Log2.d(tag, msg, null);
}
public static int d(String tag, String msg, Throwable tr) {
if (logLevels.containsKey(tag)) {
if (logLevels.get(tag) > android.util.Log.DEBUG) {
return -1;
}
}
return Log.d(tag, msg);
}
public static int i(String tag, String msg) {
return Log2.i(tag, msg, null);
}
public static int i(String tag, String msg, Throwable tr) {
if (logLevels.containsKey(tag)) {
if (logLevels.get(tag) > android.util.Log.INFO) {
return -1;
}
}
return Log.i(tag, msg);
}
public static int w(String tag, String msg) {
return Log2.w(tag, msg, null);
}
public static int w(String tag, String msg, Throwable tr) {
if (logLevels.containsKey(tag)) {
if (logLevels.get(tag) > android.util.Log.WARN) {
return -1;
}
}
return Log.w(tag, msg, tr);
}
public static int e(String tag, String msg) {
return Log2.e(tag, msg, null);
}
public static int e(String tag, String msg, Throwable tr) {
if (logLevels.containsKey(tag)) {
if (logLevels.get(tag) > android.util.Log.ERROR) {
return -1;
}
}
return Log.e(tag, msg, tr);
}
}
Now just set the log level per TAG at the beginning of each class:
Log2.setLogLevel(TAG, LogLevels.INFO);
As Except
does not modify the list, you can use ForEach on List<T>
:
list2.ForEach(item => list1.Remove(item));
It may not be the most efficient way, but it is simple, therefore readable, and it updates the original list (which is my requirement).
this might be old but my answer might help someone
You can simply use
$str = '<textformat leading="2"><p align="left"><font size="10">get me</font></p></textformat>';
echo strip_tags($str);
let storyBoard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
let home = storyBoard.instantiateViewController(withIdentifier: "HOMEVC") as! HOMEVC
navigationController?.pushViewController(home, animated: true);
Above solution does not work for me , I have tried following and it is working in all browsers.
simply made a fake ajax call, it will make a entry into referer header.
var request;
if (window.XMLHttpRequest) { // Mozilla, Safari, ...
request = new XMLHttpRequest();
} else if (window.ActiveXObject) { // IE
try {
request = new ActiveXObject('Msxml2.XMLHTTP');
} catch (e) {
try {
request = new ActiveXObject('Microsoft.XMLHTTP');
} catch (e) {}
}
}
request.open("GET", url, true);
request.send();
try this:
var span = document.getElementById("span");
span.style.fontSize = "25px";
span.innerHTML = "String";
The rolling update command, when given an image argument, assumes that the image is different than what currently exists in the replication controller.

What you have to implement in incremental steps is:
Should be :
HTML :
<form method="post" action="">
<input id="name" name="name" type="text" size="40"/>
<input type="radio" name="radio" value="test"/>Test
<input type="submit" name="submit" value="submit"/>
</form>
PHP Code :

In Android Studio, open the Device Manager: Tools -> Android -> Android Device Monitor
In Eclipse open the Device Manager:
In the device manager you can add files to the SD Card here:
set the target
attribute of your <a>
element to "_tab"
EDIT: It works, however W3Schools says there is no such target attribute: http://www.w3schools.com/tags/att_a_target.asp
EDIT2: From what I've figured out from the comments. setting target to _blank will take you to a new tab or window (depending on your browser settings). Typing anything except one of the ones below will create a new tab group (I'm not sure how these work):
_blank Opens the linked document in a new window or tab
_self Opens the linked document in the same frame as it was clicked (this is default)
_parent Opens the linked document in the parent frame
_top Opens the linked document in the full body of the window
framename Opens the linked document in a named frame
You could use Marshal.UnsafeAddrOfPinnedArrayElement
to get a memory pointer to the array (or to a specific element in the array). Keep in mind that the array must be pinned first as per the API documentation:
The array must be pinned using a GCHandle before it is passed to this method. For maximum performance, this method does not validate the array passed to it; this can result in unexpected behavior.
That will do the trick:

The debug
module can be used to analyze variables. Be careful running the following command. In our setup it generates 444709 lines with 16MB:
ansible -m debug -a 'var=hostvars' localhost
I am not sure but it might be necessary to enable facts caching.
If you need just one host use the host name as a key for the hostvars
hash:
ansible -m debug -a 'var=hostvars.localhost' localhost
Here is a general solution that doesn't rely on JQuery. Simply modify the definition of window.location.
<html>
<head>
<script>
function loadNewDoc(){
var loc = window.location;
window.location = loc.hostname + loc.port + loc.pathname + loc.search;
};
</script>
</head>
<body onLoad="loadNewDoc()">
</body>
</html>
I'd recommend you to try http://faviconer.com to convert your .PNG or .GIF to a .ICO file.
You can create both 16x16
and 32x32
(for new retina display) in one .ICO file.

I modified the script by Nicolay77 to output the database to stdout (the usual way of unix scripts) so that I could output the data to text file or pipe it to any program I want. The resulting script is a bit simpler and works well.
Some examples:
./mdb_to_mysql.sh database.mdb > data.sql
./mdb_to_mysql.sh database.mdb | mysql destination-db -u user -p
Here is the modified script (save to mdb_to_mysql.sh)
#!/bin/bash
TABLES=$(mdb-tables -1 $1)
for t in $TABLES
do
echo "DROP TABLE IF EXISTS $t;"
done
mdb-schema $1 mysql
for t in $TABLES
do
mdb-export -D '%Y-%m-%d %H:%M:%S' -I mysql $1 $t
done
The solution depends on the PHP version you are using. At least there are 2 solutions:
As @JosepAlsina said before the best and also shortest solution is to use array_column
as following:
$catIds = array_column($objects, 'id');
Notice:
For iterating an array
containing \stdClass
es as used in the question it is only possible with PHP versions >= 7.0
. But when using an array
containing array
s you can do the same since PHP >= 5.5
.
@Greg said in older PHP versions it is possible to do following:
$catIds = array_map(create_function('$o', 'return $o->id;'), $objects);
But beware: In newer PHP versions >= 5.3.0
it is better to use Closure
s, like followed:
$catIds = array_map(function($o) { return $o->id; }, $objects);
First solution creates a new function and puts it into your RAM. The garbage collector does not delete the already created and already called function instance out of memory for some reason. And that regardless of the fact, that the created function instance can never be called again, because we have no pointer for it. And the next time when this code is called, the same function will be created again. This behavior slowly fills your memory...
Both examples with memory output to compare them:
while (true)
{
$objects = array_map(create_function('$o', 'return $o->id;'), $objects);
echo memory_get_usage() . "\n";
sleep(1);
}
// the output
4235616
4236600
4237560
4238520
...
while (true)
{
$objects = array_map(function($o) { return $o->id; }, $objects);
echo memory_get_usage() . "\n";
sleep(1);
}
// the output
4235136
4235168
4235168
4235168
...
Memory leak?! Is Garbage Collector doing right when using 'create_function' within 'array_map'?
if you want to reload your entire page, like it seems, just inject $window into your controller and then call
$window.location.href = '/';
but if you only want to reload your current view, inject $scope, $state and $stateParams (the latter just in case you need to have some parameters change in this upcoming reload, something like your page number), then call this within any controller method:
$stateParams.page = 1;
$state.reload();

Yes, scripts can access properties of other windows in the same domain that they have a handle on (typically gained through window.open/opener and window.frames/parent). It is usually more manageable to call functions defined on the other window rather than fiddle with variables directly.
However, windows can die or move on, and browsers deal with it differently when they do. Check that a window (a) is still open (!window.closed) and (b) has the function you expect available, before you try to call it.
Simple values like strings are fine, but generally it isn't a good idea to pass complex objects such as functions, DOM elements and closures between windows. If a child window stores an object from its opener, then the opener closes, that object can become 'dead' (in some browsers such as IE), or cause a memory leak. Weird errors can ensue.
sigma = sum(y*(x - mean)**2)
should be
sigma = np.sqrt(sum(y*(x - mean)**2))
Make sure to invoke done();
on callbacks or it simply won't pass the test.
beforeAll((done /* Call it or remove it */ ) => {
done(); // Calling it
});
It applies to all other functions that have a done() callback.

I recently came up against a very similar problem, and believe my solution would work for you too. I had a text file which contained a list of items in the form:
["first item", 'the "Second" item', "thi'rd", 'some \\"hellish\\" \'quoted" item']
I wanted to parse the above into a python list but was not keen on eval() as I couldn't trust the input. I tried first using JSON but it only accepts double quoted items, so I wrote my own very simple lexer for this specific case (just plug in your own "stringtoparse" and you will get as output list: 'items')
#This lexer takes a JSON-like 'array' string and converts single-quoted array items into escaped double-quoted items,
#then puts the 'array' into a python list
#Issues such as ["item 1", '","item 2 including those double quotes":"', "item 3"] are resolved with this lexer
items = [] #List of lexed items
item = "" #Current item container
dq = True #Double-quotes active (False->single quotes active)
bs = 0 #backslash counter
in_item = False #True if currently lexing an item within the quotes (False if outside the quotes; ie comma and whitespace)
for c in stringtoparse[1:-1]: #Assuming encasement by brackets
if c=="\\": #if there are backslashes, count them! Odd numbers escape the quotes...
bs = bs + 1
continue
if (dq and c=='"') or (not dq and c=="'"): #quote matched at start/end of an item
if bs & 1==1: #if escaped quote, ignore as it must be part of the item
continue
else: #not escaped quote - toggle in_item
in_item = not in_item
if item!="": #if item not empty, we must be at the end
items += [item] #so add it to the list of items
item = "" #and reset for the next item
continue
if not in_item: #toggle of single/double quotes to enclose items
if dq and c=="'":
dq = False
in_item = True
elif not dq and c=='"':
dq = True
in_item = True
continue
if in_item: #character is part of an item, append it to the item
if not dq and c=='"': #if we are using single quotes
item += bs * "\\" + "\"" #escape double quotes for JSON
else:
item += bs * "\\" + c
bs = 0
continue
Hopefully it is useful to somebody. Enjoy!
In Java, what's the difference between a keystore and a truststore?
Here's the description from the Java docs at Java Secure Socket Extension (JSSE) Reference Guide. I don't think it tells you anything different from what others have said. But it does provide the official reference.
keystore/truststore
A keystore is a database of key material. Key material is used for a variety of purposes, including authentication and data integrity. Various types of keystores are available, including PKCS12 and Oracle's JKS.
Generally speaking, keystore information can be grouped into two categories: key entries and trusted certificate entries. A key entry consists of an entity's identity and its private key, and can be used for a variety of cryptographic purposes. In contrast, a trusted certificate entry contains only a public key in addition to the entity's identity. Thus, a trusted certificate entry cannot be used where a private key is required, such as in a javax.net.ssl.KeyManager. In the JDK implementation of JKS, a keystore may contain both key entries and trusted certificate entries.
A truststore is a keystore that is used when making decisions about what to trust. If you receive data from an entity that you already trust, and if you can verify that the entity is the one that it claims to be, then you can assume that the data really came from that entity.
An entry should only be added to a truststore if the user trusts that entity. By either generating a key pair or by importing a certificate, the user gives trust to that entry. Any entry in the truststore is considered a trusted entry.
It may be useful to have two different keystore files: one containing just your key entries, and the other containing your trusted certificate entries, including CA certificates. The former contains private information, whereas the latter does not. Using two files instead of a single keystore file provides a cleaner separation of the logical distinction between your own certificates (and corresponding private keys) and others' certificates. To provide more protection for your private keys, store them in a keystore with restricted access, and provide the trusted certificates in a more publicly accessible keystore if needed.
From the jQuery :input selector page:
Because :input is a jQuery extension and not part of the CSS specification, queries using :input cannot take advantage of the performance boost provided by the native DOM querySelectorAll() method. To achieve the best performance when using :input to select elements, first select the elements using a pure CSS selector, then use .filter(":input").
This is the best choice.
$('#new_user_form *').filter(':input').each(function(){
//your code here
});
Use git revert like so:
git revert <insert bad commit hash here>
git revert
creates a new commit with the changes that are rolled back. git reset
erases your git history instead of making a new commit.
The steps after are the same as any other commit.
Be sure to include the $route service into your scope and do this:
$route.reload();

cat /dev/urandom > /dev/null
If you need pixel level control over canvas you can do using createImageData and putImageData.
HTML:
<canvas id="qrCode" width="200", height="200">
QR Code
</canvas>
And JavaScript:
function setPixel(imageData, pixelData) {
var index = (pixelData.x + pixelData.y * imageData.width) * 4;
imageData.data[index+0] = pixelData.r;
imageData.data[index+1] = pixelData.g;
imageData.data[index+2] = pixelData.b;
imageData.data[index+3] = pixelData.a;
}
element = document.getElementById("qrCode");
c = element.getContext("2d");
pixcelSize = 4;
width = element.width;
height = element.height;
imageData = c.createImageData(width, height);
for (i = 0; i < 1000; i++) {
x = Math.random() * width / pixcelSize | 0; // |0 to Int32
y = Math.random() * height / pixcelSize| 0;
for(j=0;j < pixcelSize; j++){
for(k=0;k < pixcelSize; k++){
setPixel( imageData, {
x: x * pixcelSize + j,
y: y * pixcelSize + k,
r: 0 | 0,
g: 0 | 0,
b: 0 * 256 | 0,
a: 255 // 255 opaque
});
}
}
}
c.putImageData(imageData, 0, 0);
Unfortunately, there is not a direct way to do this with a single formula. However, there is a fairly simple workaround that exists.
On the Excel Ribbon, go to "Formulas" and click on "Name Manager". Select "New" and then enter "CellColor" as the "Name". Jump down to the "Refers to" part and enter the following:
=GET.CELL(63,OFFSET(INDIRECT("RC",FALSE),1,1))
Hit OK then close the "Name Manager" window.
Now, in cell A1 enter the following:
=IF(CellColor=3,"FQS",IF(CellColor=6,"SM",""))
This will return FQS for red and SM for yellow. For any other color the cell will remain blank.
***If the value in A1 doesn't update, hit 'F9' on your keyboard to force Excel to update the calculations at any point (or if the color in B2 ever changes).
Below is a reference for a list of cell fill colors (there are 56 available) if you ever want to expand things: http://www.smixe.com/excel-color-pallette.html
Cheers.
::Edit::
The formula used in Name Manager can be further simplified if it helps your understanding of how it works (the version that I included above is a lot more flexible and is easier to use in checking multiple cell references when copied around as it uses its own cell address as a reference point instead of specifically targeting cell B2).
Either way, if you'd like to simplify things, you can use this formula in Name Manager instead:
=GET.CELL(63,Sheet1!B2)
Check whether you have given python PATH in environmental variables properly.
If not, then set python path. Then use:
$ python -m notebook
This isn't a function of bash
, as all the shell does is open the file in question and then pass the file descriptor as the standard output of the script. What you need to do is make sure output is flushed from your script more frequently than you currently are.
In Perl for example, this could be accomplished by setting:
$| = 1;
See perlvar for more information on this.
An explicit default initialization can help:
struct foo {
bool a {};
bool b {};
bool c {};
} bar;
Behavior bool a {}
is same as bool b = bool();
and return false

The code is written quickly and did not refactored, raise the rating of my answer if you want me to improve the code and give ES2015 version (classes).
Try this:
DECLARE @COMBINED_STRINGS AS VARCHAR(50); -- Allocate just enough length for the two strings.
SET @COMBINED_STRINGS = 'rupesh''s' + 'malviya';
SELECT @COMBINED_STRINGS; -- Print your combined strings.
Or you can put your strings into variables. Such that:
DECLARE @COMBINED_STRINGS AS VARCHAR(50),
@STRING1 AS VARCHAR(20),
@STRING2 AS VARCHAR(20);
SET @STRING1 = 'rupesh''s';
SET @STRING2 = 'malviya';
SET @COMBINED_STRINGS = @STRING1 + @STRING2;
SELECT @COMBINED_STRINGS;
Output:
rupesh'smalviya
Just add a space in your string as a separator.

I was looking for a one-liner like:
Ask and ye shall receive. Convert from terrible legacy class Date
to its modern replacement, Instant
.
myJavaUtilDate.toInstant().toString()
2020-05-05T19:46:12.912Z
In Java 8 and later we have the new java.time package built in (Tutorial). Inspired by Joda-Time, defined by JSR 310, and extended by the ThreeTen-Extra project.
The best solution is to sort your date-time objects rather than strings. But if you must work in strings, read on.
An Instant
represents a moment on the timeline, basically in UTC (see class doc for precise details). The toString
implementation uses the DateTimeFormatter.ISO_INSTANT
format by default. This format includes zero, three, six or nine digits digits as needed to display fraction of a second up to nanosecond precision.
String output = Instant.now().toString(); // Example: '2015-12-03T10:15:30.120Z'
If you must interoperate with the old Date
class, convert to/from java.time via new methods added to the old classes. Example: Date::toInstant
.
myJavaUtilDate.toInstant().toString()
You may want to use an alternate formatter if you need a consistent number of digits in the fractional second or if you need no fractional second.
Another route if you want to truncate fractions of a second is to use ZonedDateTime
instead of Instant
, calling its method to change the fraction to zero.
Note that we must specify a time zone for ZonedDateTime
(thus the name). In our case that means UTC. The subclass of ZoneID
, ZoneOffset
, holds a convenient constant for UTC. If we omit the time zone, the JVM’s current default time zone is implicitly applied.
String output = ZonedDateTime.now( ZoneOffset.UTC ).withNano( 0 ).toString(); // Example: 2015-08-27T19:28:58Z
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes. Hibernate 5 & JPA 2.2 support java.time.
Where to obtain the java.time classes?
UPDATE: The Joda -Time project is now in maintenance mode, with the team advising migration to the java.time classes.
I was looking for a one-liner
Easy if using the Joda-Time 2.3 library. ISO 8601 is the default formatting.
In the code example below, note that I am specifying a time zone rather than depending on the default time zone. In this case, I'm specifying UTC per your question. The Z
on the end, spoken as "Zulu", means no time zone offset from UTC.
// import org.joda.time.*;
String output = new DateTime( DateTimeZone.UTC );
Output…

This brought everything back to normal.
Added this as a comment to accepted answer, but felt it deserved a longer explanation. Starting around April 2015 this will probably be raised a few times.
As of V2 of the graph api the accepted answer no longer works using a username. So now you need the userid first, and you can no longer use a username to get this. To further complicate matters, for privacy reasons, Facebook is now changing userid's per app (see https://developers.facebook.com/docs/graph-api/reference/v2.2/user/ and https://developers.facebook.com/docs/apps/upgrading/#upgrading_v2_0_user_ids ), so you will have to have some kind of proper authentication to retrieve a userid you can use. Technically the profile pic is still public and available at /userid/picture (see docs at https://developers.facebook.com/docs/graph-api/reference/v2.0/user/picture and this example user: http://graph.facebook.com/v2.2/4/picture?redirect=0) however figuring out a user's standard userid seems impossible based just on their profile - your app would need to get them to approve interaction with the app which for my use case (just showing a profile pic next to their FB profile link) is overkill.
If someone has figured out a way to get the profile pic based on username, or alternatively, how to get a userid (even an alternating one) to use to retrieve a profile pic, please share! In the meantime, the old graph url still works until April 2015.
Just cast one of the two operands to a float first.
v = (float)s / t;
The cast has higher precedence than the division, so happens before the division.
The other operand will be effectively automatically cast to a float by the compiler because the rules say that if either operand is of floating point type then the operation will be a floating point operation, even if the other operand is integral. Java Language Specification, §4.2.4 and §15.17
Here is a complete solution
<form id="form1" runat="server">
<asp:LinkButton ID="LinkButton1" runat="server" /> <%-- included to force __doPostBack javascript function to be rendered --%>
<input type="button" id="Button45" name="Button45" onclick="javascript:__doPostBack('ButtonA','')" value="clicking this will run ButtonA.Click Event Handler" /><br /><br />
<input type="button" id="Button46" name="Button46" onclick="javascript:__doPostBack('ButtonB','')" value="clicking this will run ButtonB.Click Event Handler" /><br /><br />
<asp:Button runat="server" ID="ButtonA" ClientIDMode="Static" Text="ButtonA" /><br /><br />
<asp:Button runat="server" ID="ButtonB" ClientIDMode="Static" Text="ButtonB" />
</form>
Private Sub ButtonA_Click(sender As Object, e As System.EventArgs) Handles ButtonA.Click
Response.Write("You ran the ButtonA click event")
End Sub
Private Sub ButtonB_Click(sender As Object, e As System.EventArgs) Handles ButtonB.Click
Response.Write("You ran the ButtonB click event")
End Sub
Two input controls are rendered to the client:
<input type="hidden" name="__EVENTTARGET" id="__EVENTTARGET" value="" />
<input type="hidden" name="__EVENTARGUMENT" id="__EVENTARGUMENT" value="" />
__EVENTTARGET
receives argument 1 of __doPostBack__EVENTARGUMENT
receives argument 2 of __doPostBackThe __doPostBack function is rendered out like this:
function __doPostBack(eventTarget, eventArgument) {
if (!theForm.onsubmit || (theForm.onsubmit() != false)) {
theForm.__EVENTTARGET.value = eventTarget;
theForm.__EVENTARGUMENT.value = eventArgument;
theForm.submit();
}
}
When the form submits / postback occurs:
javascript:__doPostBack('ButtonB','')
, then the button click handler for that button will be run.You can pass whatever you want as arguments to __doPostBack
You can then analyze the hidden input values and run specific code accordingly:
If Request.Form("__EVENTTARGET") = "DoSomethingElse" Then
Response.Write("Do Something else")
End If
ClientIDMode="Static"
, then you can do something like this: __doPostBack('<%= myclientid.UniqueID %>', '')
. __doPostBack('<%= MYBUTTON.UniqueID %>','')
Essentially:
<?php
//somewhere set a value
$var = "a value";
?>
<script>
// then echo it into the js/html stream
// and assign to a js variable
spge = '<?php echo $var ;?>';
// then
alert(spge);
</script>
Another great way to accomplish this is to use a transparent image with a set aspect ratio. Then set the width of the image to 100% and the height to auto. That unfortunately will push down the original content of the container. So you need to wrap the original content in another div and position it absolutely to the top of the parent div.
<div class="parent">
<img class="aspect-ratio" src="images/aspect-ratio.png" />
<div class="content">Content</div>
</div>
CSS
.parent {
position: relative;
}
.aspect-ratio {
width: 100%;
height: auto;
}
.content {
position: absolute;
width: 100%;
top: 0; left: 0;
}
To copy conditional formatting from google spreadsheet (doc1) to another (doc2) you need to do the following:
The error comes when you try to call sum(x)
and x
is a factor.
What that means is that one of your columns, though they look like numbers are actually factors (what you are seeing is the text representation)
simple fix, convert to numeric. However, it needs an intermeidate step of converting to character first. Use the following:
family[, 1] <- as.numeric(as.character( family[, 1] ))
family[, 3] <- as.numeric(as.character( family[, 3] ))
For a detailed explanation of why the intermediate as.character
step is needed, take a look at this question: How to convert a factor to integer\numeric without loss of information?
That looks like it might belong in the select statement:
SELECT id, col1, col2, col3, (CASE WHEN table3.col3 IS NULL THEN table2.col3 AS col4 ELSE table3.col3 as col4 END)
FROM table1
LEFT OUTER JOIN table2
ON table1.id = table2.id
LEFT OUTER JOIN table3
ON table1.id = table3.id
Mark's iterative approach would be the usual way, I think.
Here's an alternative with string-splitting, which can often be useful for finding-related processes:
def findnth(haystack, needle, n):
parts= haystack.split(needle, n+1)
if len(parts)<=n+1:
return -1
return len(haystack)-len(parts[-1])-len(needle)
And here's a quick (and somewhat dirty, in that you have to choose some chaff that can't match the needle) one-liner:
'foo bar bar bar'.replace('bar', 'XXX', 1).find('bar')
Update for 2018:
Now there's no need for jQuery and it's been a while since document.querySelector
or document.querySelectorAll
(for multiple elements) do almost exactly same job as $, plus more explicit ones getElementById
, getElementsByClassName
, getElementsByTagName
Disabling one field of "input-checkbox" class
document.querySelector('.input-checkbox').disabled = true;
or multiple elements
document.querySelectorAll('.input-checkbox').forEach(el => el.disabled = true);
Try:
$string = "'name', 'name2', 'name3',";
$string = rtrim($string,',');
Set the Credentials property before sending the message.
without using regex, using isdigit() built-in function, only works if starting part is text and latter part is number
def text_num_split(item):
for index, letter in enumerate(item, 0):
if letter.isdigit():
return [item[:index],item[index:]]
print(text_num_split("foobar12345"))
OUTPUT :
['foobar', '12345']
It looks like the github.com
host which jenkins tries to connect to is not listed under the Jenkins user's $HOME/.ssh/known_hosts
. Jenkins runs on most distros as the user jenkins
and hence has its own .ssh
directory to store the list of public keys and known_hosts
.
The easiest solution I can think of to fix this problem is:
# Login as the jenkins user and specify shell explicity,
# since the default shell is /bin/false for most
# jenkins installations.
sudo su jenkins -s /bin/bash
cd SOME_TMP_DIR
# git clone YOUR_GITHUB_URL
# Allow adding the SSH host key to your known_hosts
# Exit from su
exit
Emulation is a multi-faceted area. Here are the basic ideas and functional components. I'm going to break it into pieces and then fill in the details via edits. Many of the things I'm going to describe will require knowledge of the inner workings of processors -- assembly knowledge is necessary. If I'm a bit too vague on certain things, please ask questions so I can continue to improve this answer.
Emulation works by handling the behavior of the processor and the individual components. You build each individual piece of the system and then connect the pieces much like wires do in hardware.
There are three ways of handling processor emulation:
With all of these paths, you have the same overall goal: execute a piece of code to modify processor state and interact with 'hardware'. Processor state is a conglomeration of the processor registers, interrupt handlers, etc for a given processor target. For the 6502, you'd have a number of 8-bit integers representing registers: A
, X
, Y
, P
, and S
; you'd also have a 16-bit PC
register.
With interpretation, you start at the IP
(instruction pointer -- also called PC
, program counter) and read the instruction from memory. Your code parses this instruction and uses this information to alter processor state as specified by your processor. The core problem with interpretation is that it's very slow; each time you handle a given instruction, you have to decode it and perform the requisite operation.
With dynamic recompilation, you iterate over the code much like interpretation, but instead of just executing opcodes, you build up a list of operations. Once you reach a branch instruction, you compile this list of operations to machine code for your host platform, then you cache this compiled code and execute it. Then when you hit a given instruction group again, you only have to execute the code from the cache. (BTW, most people don't actually make a list of instructions but compile them to machine code on the fly -- this makes it more difficult to optimize, but that's out of the scope of this answer, unless enough people are interested)
With static recompilation, you do the same as in dynamic recompilation, but you follow branches. You end up building a chunk of code that represents all of the code in the program, which can then be executed with no further interference. This would be a great mechanism if it weren't for the following problems:
These combine to make static recompilation completely infeasible in 99% of cases. For more information, Michael Steil has done some great research into static recompilation -- the best I've seen.
The other side to processor emulation is the way in which you interact with hardware. This really has two sides:
Certain platforms -- especially older consoles like the NES, SNES, etc -- require your emulator to have strict timing to be completely compatible. With the NES, you have the PPU (pixel processing unit) which requires that the CPU put pixels into its memory at precise moments. If you use interpretation, you can easily count cycles and emulate proper timing; with dynamic/static recompilation, things are a /lot/ more complex.
Interrupts are the primary mechanism that the CPU communicates with hardware. Generally, your hardware components will tell the CPU what interrupts it cares about. This is pretty straightforward -- when your code throws a given interrupt, you look at the interrupt handler table and call the proper callback.
There are two sides to emulating a given hardware device:
Take the case of a hard-drive. The functionality is emulated by creating the backing storage, read/write/format routines, etc. This part is generally very straightforward.
The actual interface of the device is a bit more complex. This is generally some combination of memory mapped registers (e.g. parts of memory that the device watches for changes to do signaling) and interrupts. For a hard-drive, you may have a memory mapped area where you place read commands, writes, etc, then read this data back.
I'd go into more detail, but there are a million ways you can go with it. If you have any specific questions here, feel free to ask and I'll add the info.
I think I've given a pretty good intro here, but there are a ton of additional areas. I'm more than happy to help with any questions; I've been very vague in most of this simply due to the immense complexity.
It's been well over a year since this answer was submitted and with all the attention it's been getting, I figured it's time to update some things.
Perhaps the most exciting thing in emulation right now is libcpu, started by the aforementioned Michael Steil. It's a library intended to support a large number of CPU cores, which use LLVM for recompilation (static and dynamic!). It's got huge potential, and I think it'll do great things for emulation.
emu-docs has also been brought to my attention, which houses a great repository of system documentation, which is very useful for emulation purposes. I haven't spent much time there, but it looks like they have a lot of great resources.
I'm glad this post has been helpful, and I'm hoping I can get off my arse and finish up my book on the subject by the end of the year/early next year.
I made a nice helper class which converts an object with get methods to an array. It doesn't rely on properties, just methods.
So i have a the following review object which contain two methods:
Review
Comment
The script I wrote will transform it into an array with properties what looks like this:

},
{
subject: "En een zwembad 2!",

p
is the conversion specifier to print pointers. Use this.
int a = 42;
printf("%p\n", (void *) &a);
Remember that omitting the cast is undefined behavior and that printing with p
conversion specifier is done in an implementation-defined manner.
Not sure if it has changed since the accepted answer was accepted, but it is possible.
$location.search()
will return an object of key-value pairs, the same pairs as the query string. A key that has no value is just stored in the object as true. In this case, the object would be:
{"test_user_bLzgB": true}
You could access this value directly with $location.search().test_user_bLzgB
Example (with larger query string): http://fiddle.jshell.net/TheSharpieOne/yHv2p/4/show/?test_user_bLzgB&somethingElse&also&something=Somethingelse
Note: Due to hashes (as it will go to http://fiddle.jshell.net/#/url, which would create a new fiddle), this fiddle will not work in browsers that do not support js history (will not work in IE <10)
Edit:
As pointed out in the comments by @Naresh and @DavidTchepak, the $locationProvider
also needs to be configured properly: https://code.angularjs.org/1.2.23/docs/guide/$location#-location-service-configuration
To export data you need to right click on your results and select export data, after which you will be asked for a specific file format such as insert

This is now a multiple-year old question, but being very popular, it's worth mentioning a fantastic resource for learning about the C++11 memory model. I see no point in summing up his talk in order to make this yet another full answer, but given this is the guy who actually wrote the standard, I think it's well worth watching the talk.
Herb Sutter has a three hour long talk about the C++11 memory model titled "atomic<> Weapons", available on the Channel9 site - part 1 and part 2. The talk is pretty technical, and covers the following topics:
The talk doesn't elaborate on the API, but rather on the reasoning, background, under the hood and behind the scenes (did you know relaxed semantics were added to the standard only because POWER and ARM do not support synchronized load efficiently?).
WinForm:
private void button1_Click(object sender, EventArgs e)
{
button2.BackColor = Color.Red;
}
WPF:
private void button1_Click(object sender, RoutedEventArgs e)
{
button2.Background = Brushes.Blue;
}
You cannot add a column with a default value in Hive. You have the right syntax for adding the column ALTER TABLE test1 ADD COLUMNS (access_count1 int);
, you just need to get rid of default sum(max_count)
. No changes to that files backing your table will happen as a result of adding the column. Hive handles the "missing" data by interpreting NULL
as the value for every cell in that column.
So now your have the problem of needing to populate the column. Unfortunately in Hive you essentially need to rewrite the whole table, this time with the column populated. It may be easier to rerun your original query with the new column. Or you could add the column to the table you have now, then select all of its columns plus value for the new column.
You also have the option to always COALESCE
the column to your desired default and leave it NULL
for now. This option fails when you want NULL
to have a meaning distinct from your desired default. It also requires you to depend on always remembering to COALESCE
.
If you are very confident in your abilities to deal with the files backing Hive, you could also directly alter them to add your default. In general I would recommend against this because most of the time it will be slower and more dangerous. There might be some case where it makes sense though, so I've included this option for completeness.
If you need (for example) a two digit approximation for A, then
int(A*100+0.5)/100.0
will do what you are looking for.
If you need three digit approximation multiply and divide by 1000 and so on.

I suggest you to go through switch (manual).
switch ($your_variable)
{
case 1:
case 2:
echo "the value is either 1 or 2.";
break;
}
Explanation
Like for the value you want to execute a single statement for, you can put it without a break as as until or unless break is found. It will go on executing the code and if a break found, it will come out of the switch case.
Instead of explicitly writing the class name you could use
this.getClass().getResource("/unibo/lsb/res/dice.jpg");
Admitting you want to use some smtp server, you can do:
export SUBJECT=some_subject
export smtp=somehost:someport
export EMAIL=someaccount@somedomain
echo "some message" | mailx -s "$SUBJECT" "$EMAIL"
Change somehost
, someport
, and someaccount@somedomain
to actual values that you would use.
No encryption and no authentication is performed in this example.
To get the output of ls
, use stdout=subprocess.PIPE
.
>>> proc = subprocess.Popen('ls', stdout=subprocess.PIPE)
>>> output = proc.stdout.read()
>>> print output
bar
baz
foo
The command cdrecord --help
outputs to stderr, so you need to pipe that indstead. You should also break up the command into a list of tokens as I've done below, or the alternative is to pass the shell=True
argument but this fires up a fully-blown shell which can be dangerous if you don't control the contents of the command string.
>>> proc = subprocess.Popen(['cdrecord', '--help'], stderr=subprocess.PIPE)
>>> output = proc.stderr.read()
>>> print output
Usage: wodim [options] track1...trackn
Options:
-version print version information and exit
dev=target SCSI target to use as CD/DVD-Recorder
gracetime=# set the grace time before starting to write to #.
...
If you have a command that outputs to both stdout and stderr and you want to merge them, you can do that by piping stderr to stdout and then catching stdout.
subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
As mentioned by Chris Morgan, you should be using proc.communicate()
instead of proc.read()
.
>>> proc = subprocess.Popen(['cdrecord', '--help'], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> out, err = proc.communicate()
>>> print 'stdout:', out
stdout:
>>> print 'stderr:', err
stderr:Usage: wodim [options] track1...trackn
Options:
-version print version information and exit
dev=target SCSI target to use as CD/DVD-Recorder
gracetime=# set the grace time before starting to write to #.

No need of JQuery simply you can do
if(yourObject['email']){
// what if this property exists.
}
as with any value for email
will return you true
, if there is no such property or that property value is null
or undefined
will result to false
Try this:
>>> f = open('goodlines.txt')
>>> mylist = f.readlines()
open()
function returns a file object. And for file object, there is no method like splitlines()
or split()
. You could use dir(f)
to see all the methods of file object.
TL;DR
The @Autowired
annotation spares you the need to do the wiring by yourself in the XML file (or any other way) and just finds for you what needs to be injected where and does that for you.
Full explanation
The @Autowired
annotation allows you to skip configurations elsewhere of what to inject and just does it for you. Assuming your package is com.mycompany.movies
you have to put this tag in your XML (application context file):
<context:component-scan base-package="com.mycompany.movies" />
This tag will do an auto-scanning. Assuming each class that has to become a bean is annotated with a correct annotation like @Component
(for simple bean) or @Controller
(for a servlet control) or @Repository
(for DAO
classes) and these classes are somewhere under the package com.mycompany.movies
, Spring will find all of these and create a bean for each one. This is done in 2 scans of the classes - the first time it just searches for classes that need to become a bean and maps the injections it needs to be doing, and on the second scan it injects the beans. Of course, you can define your beans in the more traditional XML file or with an @Configuration
class (or any combination of the three).
The @Autowired
annotation tells Spring where an injection needs to occur. If you put it on a method setMovieFinder
it understands (by the prefix set
+ the @Autowired
annotation) that a bean needs to be injected. In the second scan, Spring searches for a bean of type MovieFinder
, and if it finds such bean, it injects it to this method. If it finds two such beans you will get an Exception
. To avoid the Exception
, you can use the @Qualifier
annotation and tell it which of the two beans to inject in the following manner:
@Qualifier("redBean")
class Red implements Color {
// Class code here
}
@Qualifier("blueBean")
class Blue implements Color {
// Class code here
}
Or if you prefer to declare the beans in your XML, it would look something like this:
<bean id="redBean" class="com.mycompany.movies.Red"/>
<bean id="blueBean" class="com.mycompany.movies.Blue"/>
In the @Autowired
declaration, you need to also add the @Qualifier
to tell which of the two color beans to inject:
@Autowired
@Qualifier("redBean")
public void setColor(Color color) {
this.color = color;
}
If you don't want to use two annotations (the @Autowired
and @Qualifier
) you can use @Resource
to combine these two:
@Resource(name="redBean")
public void setColor(Color color) {
this.color = color;
}
The @Resource
(you can read some extra data about it in the first comment on this answer) spares you the use of two annotations and instead, you only use one.
I'll just add two more comments:
@Inject
instead of @Autowired
because it is not Spring-specific and is part of the JSR-330
standard.@Inject
/ @Autowired
on a constructor instead of a method. If you put it on a constructor, you can validate that the injected beans are not null and fail fast when you try to start the application and avoid a NullPointerException
when you need to actually use the bean.Update: To complete the picture, I created a new question about the @Configuration
class.
The working version of your code (from the errors pointed out by BoltClock):
<?php
$date = '2011-01-01';
$timestamp = strtotime($date);
$weekday= date("l", $timestamp );
$normalized_weekday = strtolower($weekday);
echo $normalized_weekday ;
if (($normalized_weekday == "saturday") || ($normalized_weekday == "sunday")) {
echo "true";
} else {
echo "false";
}
?>
The stray "{" is difficult to see, especially without a decent PHP editor (in my case). So I post the corrected version here.

You can see it implemented here : Sql Fiddle Demo. Exactly what you need.
Update Splitting in two steps. First we get a table having all values(comma separated) against a unique[Name,id]. Then from obtained table we get all names and values as a single value against each unique id See this explained here SQL Fiddle Demo (scroll down as it has two result sets)
Edit There was a mistake in reading question, I had grouped only by id. But two group_contacts are needed if (Values are to be concatenated grouped by Name and id and then over all by id). Previous answer was
select
id,group_concat(concat(`name`,':',`value`) separator ',')
as Result from mytbl group by id

You need to add a reference to System.Web.Extensions.dll
in project for System.Web.Script.Serialization error.
$(window).on("touchstart", function(ev) {

I know it been asked a long time ago, but I thought a concrete example might help.
Another way: add windowNoTitle
and windowFullscreen
attributes directly to the theme (you can find styles.xml
file in res/values/
directory):
<!-- Application theme. -->
<style name="AppTheme" parent="AppBaseTheme">
<item name="android:windowNoTitle">true</item>
<item name="android:windowFullscreen">true</item>
</style>
in the manifest file, in application
specify your theme
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
If you use clearRect only, if you have it in a form to submit your drawing, you'll get a submit instead the clearing, or maybe it can be cleared first and then upload a void drawing, so you'll need to add a preventDefault at the beggining of the function:
function clearCanvas(canvas,ctx) {
event.preventDefault();
ctx.clearRect(0, 0, canvas.width, canvas.height);
}
<input type="button" value="Clear Sketchpad" id="clearbutton" onclick="clearCanvas(canvas,ctx);">
Hope it helps someone.
I believe the id accessors don't match the bean naming conventions and that's why the exception is thrown. They should be as follows:
public Integer getId() { return id; }
public void setId(Integer i){ id= i; }
Use the -p flag and add /udp
suffix to the port number.
-p 53160:53160/udp
Full command
sudo docker run -p 53160:53160 \
-p 53160:53160/udp -p 58846:58846 \
-p 8112:8112 -t -i aostanin/deluge /start.sh
If you're running boot2docker on Mac, be sure to forward the same ports on boot2docker to your local machine.
You can also document that your container needs to receive UDP using EXPOSE in The Dockerfile
(EXPOSE does not publish the port):
EXPOSE 8285/udp
Here is a link with more Docker Networking info covered in the container docs: https://docs.docker.com/config/containers/container-networking/ (Courtesy of Old Pro in the comments)
You can do this by creating a constraint and connecting it via interface builder

AutolayoutPG Articles constraint Fundamentals
@interface ViewController : UIViewController {
IBOutlet NSLayoutConstraint *leadingSpaceConstraint;
IBOutlet NSLayoutConstraint *topSpaceConstraint;
}
@property (weak, nonatomic) IBOutlet NSLayoutConstraint *leadingSpaceConstraint;
connect this Constraint outlet with your sub views Constraint or connect super views Constraint too and set it according to your requirements like this
self.leadingSpaceConstraint.constant = 10.0;//whatever you want to assign
I hope this clarifies it.
Spring won't allow to decouple via java.util.Properties

If you're more into gaming you can use PyGame for GUIs.
You can continue using WebClient to POST (instead of GET, which is the HTTP verb you're currently using with DownloadString), but I think you'll find it easier to work with the (slightly) lower-level classes WebRequest and WebResponse.
There are two parts to this - the first is to post the login form, the second is recovering the "Set-cookie" header and sending that back to the server as "Cookie" along with your GET request. The server will use this cookie to identify you from now on (assuming it's using cookie-based authentication which I'm fairly confident it is as that page returns a Set-cookie header which includes "PHPSESSID").
POSTing to the login form
Form posts are easy to simulate, it's just a case of formatting your post data as follows:
field1=value1&field2=value2
Using WebRequest and code I adapted from Scott Hanselman, here's how you'd POST form data to your login form:
string formUrl = "http://www.mmoinn.com/index.do?PageModule=UsersAction&Action=UsersLogin"; // NOTE: This is the URL the form POSTs to, not the URL of the form (you can find this in the "action" attribute of the HTML's form tag
string formParams = string.Format("email_address={0}&password={1}", "your email", "your password");
string cookieHeader;
WebRequest req = WebRequest.Create(formUrl);
req.ContentType = "application/x-www-form-urlencoded";
req.Method = "POST";
byte[] bytes = Encoding.ASCII.GetBytes(formParams);
req.ContentLength = bytes.Length;
using (Stream os = req.GetRequestStream())
{
os.Write(bytes, 0, bytes.Length);
}
WebResponse resp = req.GetResponse();
cookieHeader = resp.Headers["Set-cookie"];
Here's an example of what you should see in the Set-cookie header for your login form:
PHPSESSID=c4812cffcf2c45e0357a5a93c137642e; path=/; domain=.mmoinn.com,wowmine_referer=directenter; path=/; domain=.mmoinn.com,lang=en; path=/;domain=.mmoinn.com,adt_usertype=other,adt_host=-
GETting the page behind the login form
Now you can perform your GET request to a page that you need to be logged in for.
string pageSource;
string getUrl = "the url of the page behind the login";
WebRequest getRequest = WebRequest.Create(getUrl);
getRequest.Headers.Add("Cookie", cookieHeader);
WebResponse getResponse = getRequest.GetResponse();
using (StreamReader sr = new StreamReader(getResponse.GetResponseStream()))
{
pageSource = sr.ReadToEnd();
}
EDIT:
If you need to view the results of the first POST, you can recover the HTML it returned with:
using (StreamReader sr = new StreamReader(resp.GetResponseStream()))
{
pageSource = sr.ReadToEnd();
}
Place this directly below cookieHeader = resp.Headers["Set-cookie"];
and then inspect the string held in pageSource.
In another way to limit a string in php and add on readmore text or like '...' using below code
if (strlen(preg_replace('#^https?://#', '', $string)) > 30) {
echo substr(preg_replace('#^https?://#', '', $string), 0, 35).'…';
}
This is just an indentation problem since Python is very strict when it comes to it.
If you are using Sublime, you can select all, click on the lower right beside 'Python' and make sure you check 'Indent using spaces' and choose your Tab Width to be consistent, then Convert Indentation to Spaces to convert all tabs to spaces.
You need to declare your event in the class from myObject :
public event EventHandler<EventArgs> myMethod; //you should name it as an event, like ObjectChanged.
then myNameEvent is the callback to handle the event, and it can be in any other class
The JSON.stringify
method supported by many modern browsers (including IE8) can output a beautified JSON string:
JSON.stringify(jsObj, null, "\t"); // stringify with tabs inserted at each level
JSON.stringify(jsObj, null, 4); // stringify with 4 spaces at each level
Demo: http://jsfiddle.net/AndyE/HZPVL/
This method is also included with json2.js, for supporting older browsers.
If you don't need to do it programmatically, Try JSON Lint. Not only will it prettify your JSON, it will validate it at the same time.
For a specific column, there is an alternative with sapply
DF <- data.frame(A = letters[1:5],
B = letters[6:10],
C = c(2, 5, NA, 8, NA))
DF_NEW <- sapply(seq(1, nrow(DF)),
function(i) ifelse(is.na(DF[i,3]) ==
TRUE,
0,
DF[i,3]))
DF[,3] <- DF_NEW

A GridView is a ViewGroup that displays items in two-dimensional scrolling grid. The items in the grid come from the ListAdapter associated with this view.
This is what you'd want to use (keep using). Because a GridView gets its data from a ListAdapter, the only data loaded in memory will be the one displayed on screen. GridViews, much like ListViews reuse and recycle their views for better performance.
Whereas a GridLayout is a layout that places its children in a rectangular grid.
It was introduced in API level 14, and was recently backported in the Support Library. Its main purpose is to solve alignment and performance problems in other layouts. Check out this tutorial if you want to learn more about GridLayout.
Add this style to your style.xml file
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
After that reference this style name into your androidManifest.xml in perticular activity in which you don't want to see titlebar, as like below.
<activity android:name=".youractivityname"
android:theme="@style/AppTheme.NoActionBar">
</activity>
>>> item = set([0,1,2,3,4,5,6,7,8,9])
>>> z = set([2,3,4])
>>> print item - z
set([0, 1, 5, 6, 7, 8, 9])
This worked for me:
location / {
try_files $uri $uri/ /base.html;
}
I am listing the difference in each of the casting ways. What a particular type of casting handles and it doesn't?
// object to int
// does not handle null
// does not handle NAN ("102art54")
// convert value to integar
int intObj = (int)obj;
// handles only null or number
int? nullableIntObj = (int?)obj; // null
Nullable<int> nullableIntObj1 = (Nullable<int>)obj; // null
// best way for casting from object to nullable int
// handles null
// handles other datatypes gives null("sadfsdf") // result null
int? nullableIntObj2 = obj as int?;
// string to int
// does not handle null( throws exception)
// does not string NAN ("102art54") (throws exception)
// converts string to int ("26236")
// accepts string value
int iVal3 = int.Parse("10120"); // throws exception value cannot be null;
// handles null converts null to 0
// does not handle NAN ("102art54") (throws exception)
// converts obj to int ("26236")
int val4 = Convert.ToInt32("10120");
// handle null converts null to 0
// handle NAN ("101art54") converts null to 0
// convert string to int ("26236")
int number;
bool result = int.TryParse(value, out number);
if (result)
{
// converted value
}
else
{
// number o/p = 0
}
Use double braces {{
or }}
so your code becomes:
sb.AppendLine(String.Format("public {0} {1} {{ get; private set; }}",
prop.Type, prop.Name));
// For prop.Type of "Foo" and prop.Name of "Bar", the result would be:
// public Foo Bar { get; private set; }
While building an algorithm in Python (interpreted language) that incorporated multi-threading I was surprised to see that execution time was not any better when compared to the sequential algorithm I had previously built. In an effort to understand the reason for this result I did some reading, and believe what I learned offers an interesting context from which to better understand the differences between multi-threading and multi-processes.
Multi-core systems may exercise multiple threads of execution, and so Python should support multi-threading. But Python is not a compiled language and instead is an interpreted language1. This means that the program must be interpreted in order to run, and the interpreter is not aware of the program before it begins execution. What it does know, however, are the rules of Python and it then dynamically applies those rules. Optimizations in Python must then be principally optimizations of the interpreter itself, and not the code that is to be run. This is in contrast to compiled languages such as C++, and has consequences for multi-threading in Python. Specifically, Python uses the Global Interpreter Lock to manage multi-threading.
On the other hand a compiled language is, well, compiled. The program is processed "entirely", where first it is interpreted according to its syntactical definitions, then mapped to a language agnostic intermediate representation, and finally linked into an executable code. This process allows the code to be highly optimized because it is all available at the time of compilation. The various program interactions and relationships are defined at the time the executable is created and robust decisions about optimization can be made.
In modern environments Python's interpreter must permit multi-threading, and this must both be safe and efficient. This is where the difference between being an interpreted language versus a compiled language enters the picture. The interpreter must not to disturb internally shared data from different threads, while at the same time optimizing the use of processors for computations.
As has been noted in the previous posts both a process and a thread are independent sequential executions with the primary difference being that memory is shared across multiple threads of a process, while processes isolate their memory spaces.
In Python data is protected from simultaneous access by different threads by the Global Interpreter Lock. It requires that in any Python program only one thread can be executed at any time. On the other hand it is possible to run multiple processes since the memory for each process is isolated from any other process, and processes can run on multiple cores.
1 Donald Knuth has a good explanation of interpretive routines in The Art of Computer Programming: Fundamental Algorithms.
The below code gives you the simple extrapolation module. k is the value to which the data set y has to be extrapolated based on the data set x. The numpy
module is required.
def extrapol(k,x,y):
xm=np.mean(x);
ym=np.mean(y);
sumnr=0;
sumdr=0;
length=len(x);
for i in range(0,length):
sumnr=sumnr+((x[i]-xm)*(y[i]-ym));
sumdr=sumdr+((x[i]-xm)*(x[i]-xm));
m=sumnr/sumdr;
c=ym-(m*xm);
return((m*k)+c)
Just append a div
with that class to body
, then remove it when you're done:
// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);
// Remove it (later)
$(".modal-backdrop").remove();
Live Example:
$("input").click(function() {_x000D_
var bd = $('<div class="modal-backdrop"></div>');_x000D_
bd.appendTo(document.body);_x000D_
setTimeout(function() {_x000D_

Check out this blog post from Nemikor, which should do what you want.
http://blog.nemikor.com/2009/04/18/loading-a-page-into-a-dialog/
Basically, before calling 'open', you 'load' the content from the other page first.
jQuery('#dialog').load('path to my page').dialog('open');
Thank you so much for that class, Cristian.
I made a minor tweak to it so that the custom loading view is optional, like so:
@Override
public View getVideoLoadingProgressView() // Video will start loading, only called in the case of VideoView (typically API level 10-)
{
if (loadingView == null)
{
return super.getVideoLoadingProgressView();
}
else
{
loadingView.setVisibility(View.VISIBLE);
return loadingView;
}
}
I also added a new constructor that just takes two parameters. Anyway, just a minor simplification if you don't need the loading view. Thanks again for providing this.
When you click the Button
if(isset($_POST['save'])){
$sql = "INSERT INTO `members`(`id`, `membership_id`, `email`, `first_name`)
VALUES ('".$_POST["id"]."','".$_POST["membership_id"]."','".$_POST["email"]."','".$_POST["firstname"]."')";
**if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}**
}
This will execute the Query in the variable $sql
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
Since not all of my clients use authenticated SMTP accounts, I resorted to using the SMTP account only if app key values are supplied in web.config file.
Here is the VB code:
sSMTPUser = ConfigurationManager.AppSettings("SMTPUser")
sSMTPPassword = ConfigurationManager.AppSettings("SMTPPassword")
If sSMTPUser.Trim.Length > 0 AndAlso sSMTPPassword.Trim.Length > 0 Then
NetClient.Credentials = New System.Net.NetworkCredential(sSMTPUser, sSMTPPassword)
sUsingCredentialMesg = "(Using Authenticated Account) " 'used for logging purposes
End If
NetClient.Send(Message)
The following function converts an integer to binary in a string (n is the number of bits):

The following function converts an integer to binary in a string and allocate memory for the string (n is the number of bits):
// Convert an integer to binary (in a string)
char* int2bin(unsigned integer, int n=8)
{
char* binary = (char*)malloc(n+1);
for (int i=0;i<n;i++)
binary[i] = (integer & (int)1<<(n-i-1)) ? '1' : '0';
binary[n]='\0';
return binary;
}
This option allows you to write something like printf ("%s", int2bin(78));
but be careful, memory allocated for the string must be free later.

Just to update this question for mod_security 2.7.0+ - they turned off the ability to mitigate modsec via htaccess unless you compile it with the --enable-htaccess-config
flag. Most hosts do not use this compiler option since it allows too lax security. Instead, vhosts in httpd.conf are your go-to option for controlling modsec.
Even if you do compile modsec with htaccess mitigation, there are less directives available. SecRuleEngine
can no longer be used there for example. Here is a list that is available to use by default in htaccess if allowed (keep in mind a host may further limit this list with AllowOverride
):
- SecAction
- SecRule
- SecRuleRemoveByMsg
- SecRuleRemoveByTag
- SecRuleRemoveById
- SecRuleUpdateActionById
- SecRuleUpdateTargetById
- SecRuleUpdateTargetByTag
- SecRuleUpdateTargetByMsg
More info on the official modsec wiki
As an additional note for 2.x users: the IfModule
should now look for mod_security2.c
instead of the older mod_security.c
I don't think it's bad to use any?
at all. I use it a lot. It's clear and concise.
However if you are concerned about all nil
values throwing it off, then you are really asking if the array has size > 0
. In that case, this dead simple extension (NOT optimized, monkey-style) would get you close.
Object.class_eval do
def size?
respond_to?(:size) && size > 0
end
end
> "foo".size?
=> true
> "".size?
=> false
> " ".size?
=> true
> [].size?
=> false
> [11,22].size?
=> true
> [nil].size?
=> true
This is fairly descriptive, logically asking "does this object have a size?". And it's concise, and it doesn't require ActiveSupport. And it's easy to build on.
Some extras to think about:
present?
from ActiveSupport.String
, that ignores whitespace (like present?
does).length?
for String
or other types where it might be more descriptive.Integer
and other Numeric
types, so that a logical zero returns false
.Try this for selecting div by first id
$('div[id^="c-"]')
public interface IService {
String BASE_URL = "https://api.demo.com/";
@GET("Login") //i.e https://api.demo.com/Search?
Call<Products> getUserDetails(@Query("email") String emailID, @Query("password") String password)
}
It will be called this way. Considering you did the rest of the code already.
Call<Results> call = service.getUserDetails("[email protected]", "Password@123");
For example when a query is returned, it will look like this.
https://api.demo.com/[email protected]&password=Password@123
None of the other answers dealt with the case of using .children()
or .find(">")
to only search for immediate children of a parent element. So, I created a jsPerf test to find out, using three different ways to distinguish children.
As it happens, even when using the extra ">" selector, .find()
is still a lot faster than .children()
; on my system, 10x so.
So, from my perspective, there does not appear to be much reason to use the filtering mechanism of .children()
at all.
A slight extension to the answer given, so, hopefully useful to the asker and anyone else looking.
You can also SELECT
the values you want to delete. But watch out for the Error 1093 - You can't specify the target table for update in FROM clause.
DELETE FROM
orders_products_history
WHERE
(branchID, action) IN (
SELECT
branchID,
action
FROM
(
SELECT
branchID,
action
FROM
orders_products_history
GROUP BY
branchID,
action
HAVING
COUNT(*) > 10000
) a
);
I wanted to delete all history records where the number of history records for a single action/branch exceed 10,000. And thanks to this question and chosen answer, I can.
Hope this is of use.
Richard.
In my case, it seems that the crawler is just having a bug. I've tried:
None of these works. This costed me a week. And suddenly out of nowhere it seems to work again.
Here are my research, if someone meets this problem again:
What makes Open Graph checkers unable to detect Open Graph data?
How to know what bots of a website, if I have no root access to the hosting they will read?
What makes Open Graph checkers unable to detect Open Graph data? - Let's Encrypt Community Support
Also, there are more checkers other than the Facebook's Object Debugger for you to check: OpenGraphCheck.com, Abhinay Rathore's Open Graph Tester, Iframely's Embed Codes, Card Validator | Twitter Developers.
I changed the ownership of the wordpress folder to www-data recursively and restarted apache.
sudo chown -R www-data:www-data <folderpath>
It worked like a charm!
In my case I had all these worked except for the correct character recognition.
But you need to consider these few things:
ocr.Init(@"c:\tessdata", "eng", true);
hope that this helps

I tried http://gitstats.sourceforge.net/, starts are very interesting.
Once git clone git://repo.or.cz/gitstats.git
is done, go to that folder and say gitstats <git repo location> <report output folder>
(create a new folder for report as this generates lots of files)
Here is a quick list of stats from this:
Building on @boulder_ruby's answer, this is what I'm looking for, assuming us_eco

us_eco.each do |row|
csvfile << row.values
end

Branches in SVN are essentially directories; you don't name the branch so much as choose the name of the directory to branch into.
The common way of 'naming' a branch is to place it under a directory called branches
in your repository. In the "To URL:" portion of TortoiseSVN's Branch dialog, you would therefore enter something like:
(svn/http)://path-to-repo/branches/your-branch-name
The main branch of a project is referred to as the trunk, and is usually located in:
(svn/http)://path-to-repo/trunk
While this is an old post, I recently came across it when I was looking for a solution to the same issue. While the above solutions do prevent charts from plotting data (when source cells are #N/A or made to look blank), it doesn't resolve the issue of the chart data labels themselves still showing a zero label.
I had searched and searched and almost given up, when I came across the solution posted online @ https://www.extendoffice.com/documents/excel/2031-excel-hide-zero-data-labels.html
It worked liked a charm. Attached is an image showing an example of how the data (labels) displayed before, Chart#1, and how it displays using this tip chart#2.
To make things really simple you can use DateJS, a date library for JavaScript:

If you're purely using underscore.js, it doesn't have unionWith, unionBy
you can try out :
_.uniq(_.union(arr1, arr2), (obj) => obj.key)
( key is the key param of each object )
this should help to get unique after union of both arrays.
I wanted to keep the formulas in place, which the above code did not do.

for LOCAL_MACHINE.reg add "HKEY_CURRENT_USER\Environment" /v shared_dir /d "c:\shared" /t REG_SZ
. Use REG_EXPAND_SZ
for paths containing other %% variables.reg delete "HKEY_CURRENT_USER\Environment" /v shared_dir
.I do this simply by passing the user credentials to ldap_bind().

Follow the simple steps to rename your app name
and Package name
in case you have not made any custom changes in android folder(ie. scenario where u just initialized the project)
name
in the package.json
file as you need and save it.react-native upgrade
Note:As ivoteje50 mentioned in comment,Don't remove the android folder if you have already followed the official instructions to generate a keystore, since it will remove the keystore and you cannot sign a new app again.

There is a blog post with brief source code sample about how misuse of IEnumerable<T>
can dramatically impact LINQ query performance: Entity Framework: IQueryable vs. IEnumerable.
If we dig deeper and look into the sources, we can see that there are obviously different extension methods are perfomed for IEnumerable<T>
:
// Type: System.Linq.Enumerable
// Assembly: System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
// Assembly location: C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Core.dll
public static class Enumerable
{
public static IEnumerable<TSource> Where<TSource>(
this IEnumerable<TSource> source,
Func<TSource, bool> predicate)
{
return (IEnumerable<TSource>)
new Enumerable.WhereEnumerableIterator<TSource>(source, predicate);
}
}
and IQueryable<T>
:
// Type: System.Linq.Queryable
// Assembly: System.Core, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
// Assembly location: C:\Windows\Microsoft.NET\Framework\v4.0.30319\System.Core.dll
public static class Queryable
{
public static IQueryable<TSource> Where<TSource>(
this IQueryable<TSource> source,
Expression<Func<TSource, bool>> predicate)
{
return source.Provider.CreateQuery<TSource>(
Expression.Call(
null,
((MethodInfo) MethodBase.GetCurrentMethod()).MakeGenericMethod(
new Type[] { typeof(TSource) }),
new Expression[]
{ source.Expression, Expression.Quote(predicate) }));
}
}
The first one returns enumerable iterator, and the second one creates query through the query provider, specified in IQueryable
source.
You may use a controller in directive:
angular.module('app', [])
.directive('appClick', function(){
return {
restrict: 'A',
scope: true,
template: '<button ng-click="click()">Click me</button> Clicked {{clicked}} times',
controller: function($scope, $element){
$scope.clicked = 0;
$scope.click = function(){
$scope.clicked++
}
}
}
});
More about directives in Angular guide. And very helpfull for me was videos from official Angular blog post About those directives.
According to Swift 4 Documentation, String values can be added together (or concatenated) with the addition operator (+) to create a new String value:
let string1 = "hello"
let string2 = " there"
var welcome = string1 + string2
// welcome now equals "hello there"
You can also append a String value to an existing String variable with the addition assignment operator (+=):
var instruction = "look over"
instruction += string2
// instruction now equals "look over there"
You can append a Character value to a String variable with the String type’s append() method:
let exclamationMark: Character = "!"
welcome.append(exclamationMark)
// welcome now equals "hello there!"
MaxLength is used for the Entity Framework to decide how large to make a string value field when it creates the database.
From MSDN:
Specifies the maximum length of array or string data allowed in a property.
StringLength is a data annotation that will be used for validation of user input.
From MSDN:
Specifies the minimum and maximum length of characters that are allowed in a data field.
Use [String Length]
[RegularExpression(@"^.{3,}$", ErrorMessage = "Minimum 3 characters required")]
[Required(ErrorMessage = "Required")]
[StringLength(30, MinimumLength = 3, ErrorMessage = "Maximum 30 characters")]
30 is the Max Length
Minimum length = 3
public class MyStringLengthAttribute : StringLengthAttribute
{
public MyStringLengthAttribute(int maximumLength)
: base(maximumLength)
{
}
public override bool IsValid(object value)
{
string val = Convert.ToString(value);
if (val.Length < base.MinimumLength)
base.ErrorMessage = "Minimum length should be 3";
if (val.Length > base.MaximumLength)
base.ErrorMessage = "Maximum length should be 6";
return base.IsValid(value);
}
}
public class MyViewModel
{
[MyStringLength(6, MinimumLength = 3)]
public String MyProperty { get; set; }

It is represented in reverse DNS notation and it is recommended that you use your company name and application name to create it.
An example bundle ID for an App called The Best App by a company called Awesome Apps would look like:
com.awesomeapps.thebestapp
In this case the suffix is thebestapp
