In a regular expression, you can "capture" parts of the matched string with (brackets)
; in this case, you are capturing the (^|_)
and ([a-z])
parts of the match. These are numbered starting at 1, so you have back-references 1 and 2. Match 0 is the whole matched string.
The /e
modifier takes a replacement string, and substitutes backslash followed by a number (e.g. \1
) with the appropriate back-reference - but because you're inside a string, you need to escape the backslash, so you get '\\1'
. It then (effectively) runs eval
to run the resulting string as though it was PHP code (which is why it's being deprecated, because it's easy to use eval
in an insecure way).
The preg_replace_callback
function instead takes a callback function and passes it an array containing the matched back-references. So where you would have written '\\1'
, you instead access element 1 of that parameter - e.g. if you have an anonymous function of the form function($matches) { ... }
, the first back-reference is $matches[1]
inside that function.
So a /e
argument of
'do_stuff(\\1) . "and" . do_stuff(\\2)'
could become a callback of
function($m) { return do_stuff($m[1]) . "and" . do_stuff($m[2]); }
Or in your case
'strtoupper("\\2")'
could become
function($m) { return strtoupper($m[2]); }
Note that $m
and $matches
are not magic names, they're just the parameter name I gave when declaring my callback functions. Also, you don't have to pass an anonymous function, it could be a function name as a string, or something of the form array($object, $method)
, as with any callback in PHP, e.g.
function stuffy_callback($things) {
return do_stuff($things[1]) . "and" . do_stuff($things[2]);
}
$foo = preg_replace_callback('/([a-z]+) and ([a-z]+)/', 'stuffy_callback', 'fish and chips');
As with any function, you can't access variables outside your callback (from the surrounding scope) by default. When using an anonymous function, you can use the use
keyword to import the variables you need to access, as discussed in the PHP manual. e.g. if the old argument was
'do_stuff(\\1, $foo)'
then the new callback might look like
function($m) use ($foo) { return do_stuff($m[1], $foo); }
preg_replace_callback
is instead of the /e
modifier on the regex, so you need to remove that flag from your "pattern" argument. So a pattern like /blah(.*)blah/mei
would become /blah(.*)blah/mi
./e
modifier used a variant of addslashes()
internally on the arguments, so some replacements used stripslashes()
to remove it; in most cases, you probably want to remove the call to stripslashes
from your new callback.You can use an anonymous function to pass the matches to your function:
$result = preg_replace_callback(
"/\{([<>])([a-zA-Z0-9_]*)(\?{0,1})([a-zA-Z0-9_]*)\}(.*)\{\\1\/\\2\}/isU",
function($m) { return CallFunction($m[1], $m[2], $m[3], $m[4], $m[5]); },
$result
);
Apart from being faster, this will also properly handle double quotes in your string. Your current code using /e
would convert a double quote "
into \"
.
Ansible command-line help, such as ansible-playbook --help
shows how to increase output verbosity by setting the verbose mode (-v) to more verbosity (-vvv) or to connection debugging verbosity (-vvvv). This should give you some of the details you're after in stdout, which you can then be logged.
Try with the below code it`s working for me.
public static String decrypt(String encrypted) throws NoSuchAlgorithmException, NoSuchPaddingException, InvalidKeyException, InvalidAlgorithmParameterException, IllegalBlockSizeException, BadPaddingException, UnsupportedEncodingException {
byte[] key = your Key in byte array;
byte[] input = salt in byte array;
SecretKeySpec skeySpec = new SecretKeySpec(key, "AES");
IvParameterSpec ivSpec = new IvParameterSpec(input);
Cipher ecipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
ecipher.init(Cipher.DECRYPT_MODE, skeySpec, ivSpec);
byte[] raw = Base64.decode(encrypted, Base64.DEFAULT);
byte[] originalBytes = ecipher.doFinal(raw);
String original = new String(originalBytes, "UTF8");
return original;
}
The annotation mappedBy ideally should always be used in the Parent side (Company class) of the bi directional relationship, in this case it should be in Company class pointing to the member variable 'company' of the Child class (Branch class)
The annotation @JoinColumn is used to specify a mapped column for joining an entity association, this annotation can be used in any class (Parent or Child) but it should ideally be used only in one side (either in parent class or in Child class not in both) here in this case i used it in the Child side (Branch class) of the bi directional relationship indicating the foreign key in the Branch class.
below is the working example :
parent class , Company
@Entity
public class Company {
private int companyId;
private String companyName;
private List<Branch> branches;
@Id
@GeneratedValue
@Column(name="COMPANY_ID")
public int getCompanyId() {
return companyId;
}
public void setCompanyId(int companyId) {
this.companyId = companyId;
}
@Column(name="COMPANY_NAME")
public String getCompanyName() {
return companyName;
}
public void setCompanyName(String companyName) {
this.companyName = companyName;
}
@OneToMany(fetch=FetchType.LAZY,cascade=CascadeType.ALL,mappedBy="company")
public List<Branch> getBranches() {
return branches;
}
public void setBranches(List<Branch> branches) {
this.branches = branches;
}
}
child class, Branch
@Entity
public class Branch {
private int branchId;
private String branchName;
private Company company;
@Id
@GeneratedValue
@Column(name="BRANCH_ID")
public int getBranchId() {
return branchId;
}
public void setBranchId(int branchId) {
this.branchId = branchId;
}
@Column(name="BRANCH_NAME")
public String getBranchName() {
return branchName;
}
public void setBranchName(String branchName) {
this.branchName = branchName;
}
@ManyToOne(fetch=FetchType.LAZY)
@JoinColumn(name="COMPANY_ID")
public Company getCompany() {
return company;
}
public void setCompany(Company company) {
this.company = company;
}
}

In this case it would probably be better to just have an empty database that you use as a template and when you need to refresh, drop the existing database and create a new one from the template.
I know this answer is coming 3 years late but none of the other answers are indeed 100% correct. If you would like to detect if the user is on ANY form of mobile device (Android, iOS, BlackBerry, Windows Phone, Kindle, etc.), then you can use the following code:
if (/Android|webOS|iPhone|iPad|iPod|BlackBerry|BB|PlayBook|IEMobile|Windows Phone|Kindle|Silk|Opera Mini/i.test(navigator.userAgent)) {
// Take the user to a different screen here.
}
Swift 2.0
// Checking if app is running iOS 8
if application.respondsToSelector("isRegisteredForRemoteNotifications") {
print("registerApplicationForPushNotifications - iOS 8")
application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: [.Alert, .Badge, .Sound], categories: nil));
application.registerForRemoteNotifications()
} else {
// Register for Push Notifications before iOS 8
print("registerApplicationForPushNotifications - <iOS 8")
application.registerForRemoteNotificationTypes([UIRemoteNotificationType.Alert, UIRemoteNotificationType.Badge, UIRemoteNotificationType.Sound])
}
arr=("sharlock" "bomkesh" "feluda" ) ##declare array
len=${#arr[*]} #determine length of array
# iterate with for loop
for (( i=0; i<len; i++ ))
do
echo ${arr[$i]}
done
If you do not want to install Xcode and/or MacPorts/Fink/Homebrew, you could always use the standalone installer: https://sourceforge.net/projects/git-osx-installer/
I had the same problem for different package. I was installing pyinstaller
in conda on Mac Mojave. I did
conda create --name ai37 python=3.7
conda activate ai37
I got the mentioned error when I tried to install pyinstaller using
pip install pyinstaller
I was able to install the pyinstaller with the following command
conda install -c conda-forge pyinstaller
Create a SQLCLR assembly with external access permission that returns the list of files as a result set. There are many examples how to do this, eg. Yet another TVF: returning files from a directory or Trading in xp_cmdshell for SQLCLR (Part 1) - List Directory Contents.
Please check the class you inherited. Whether it is simply Controller or APIController.
By mistake we might create a controller from MVC 5 controller. It should be from Web API Controller.
Update: As of jQuery 1.4 you can use the .delay( n )
method. http://api.jquery.com/delay/
$('.notice').fadeIn().delay(2000).fadeOut('slow');
Note: $.show()
and $.hide()
by default are not queued, so if you want to use $.delay()
with them, you need to configure them that way:
$('.notice')
.show({duration: 0, queue: true})
.delay(2000)
.hide({duration: 0, queue: true});
You could possibly use the Queue syntax, this might work:
jQuery(function($){
var e = $('.notice');
e.fadeIn();
e.queue(function(){
setTimeout(function(){
e.dequeue();
}, 2000 );
});
e.fadeOut('fast');
});
or you could be really ingenious and make a jQuery function to do it.
(function($){
jQuery.fn.idle = function(time)
{
var o = $(this);
o.queue(function()
{
setTimeout(function()
{
o.dequeue();
}, time);
});
};
})(jQuery);
which would ( in theory , working on memory here ) permit you do to this:
$('.notice').fadeIn().idle(2000).fadeOut('slow');
Unless you unpack them, assets remain inside the apk. Accordingly, there isn't a path you can feed into a File. The path you've given in your question will work with/in a WebView, but I think that's a special case for WebView.
You'll need to unpack the file or use it directly.
If you have a Context, you can use context.getAssets().open("myfoldername/myfilename");
to open an InputStream on the file. With the InputStream you can use it directly, or write it out somewhere (after which you can use it with File).
In js you can change zoom by
document.body.style.zoom="90%"
But it doesn't work in FF http://caniuse.com/#search=zoom
For ff you can try
-moz-transform: scale(0.9);
And check next topic How can I zoom an HTML element in Firefox and Opera?
If you want to load the file, as part of your app functionality, then the best approach would be to include and reference to that file.
Another approach is to ask for the file, and load it during runtime. This can be done with the FileAPI. There is also another StackOverflow answer about using it: How to open a local disk file with Javascript?
I will include a slightly modified version for using it in React:
class App extends React.Component {
constructor(props) {
super(props);
this.state = {
data: null
};
this.handleFileSelect = this.handleFileSelect.bind(this);
}
displayData(content) {
this.setState({data: content});
}
handleFileSelect(evt) {
let files = evt.target.files;
if (!files.length) {
alert('No file select');
return;
}
let file = files[0];
let that = this;
let reader = new FileReader();
reader.onload = function(e) {
that.displayData(e.target.result);
};
reader.readAsText(file);
}
render() {
const data = this.state.data;
return (
<div>
<input type="file" onChange={this.handleFileSelect}/>
{ data && <p> {data} </p> }
</div>
);
}
}
It's a reference to the current object, it's most commonly used in object oriented code.
Example:
<?php
class Person {
public $name;
function __construct( $name ) {
$this->name = $name;
}
};
$jack = new Person('Jack');
echo $jack->name;
This stores the 'Jack' string as a property of the object created.
You can also do it in the "mathematical" way without treating the number as a string:
var num = 278;_x000D_
var digits = [];_x000D_
while (num > 0) {_x000D_
digits.push(num % 10);_x000D_
num = parseInt(num / 10);_x000D_
}_x000D_
digits.reverse();_x000D_
console.log(digits);
_x000D_
One upside I can see is that you won't have to run parseInt()
on every digit, you're dealing with the actual digits as numeric values.
Jenkins lets you set up multiple times, separated by line breaks.
If you need it to build daily at 7 am, along with every Sunday at 4 pm, the below works well.

Okay guys another sleek option is
Application.Context.ApplicationInfo.NonLocalizedLabel
verified for hard coded android label on application element.
<application android:label="Big App"></application>
Reference: http://developer.android.com/reference/android/content/pm/PackageItemInfo.html#nonLocalizedLabel
I had a similar problem. To solve this (instead of calculate the iframe's height using the body, document or window) I created a div that wraps the whole page content (a div with an id="page" for example) and then I used its height.
use this JavaScript code:
<script>
setTimeout(function(){
window.location.href = 'form2.html';
}, 5000);
</script>
Quote your args in Testscript 1:
echo "TestScript1 Arguments:"
echo "$1"
echo "$2"
echo "$#"
./testscript2 "$1" "$2"
This doesn't say how to "fix" the problem - that's already been done in other answers; it exists to draw out the details and applicable documentation references.
When using String.replaceAll
or any of the applicable Matcher replacers, pay attention to the replacement string and how it is handled:
Note that backslashes (
\
) and dollar signs ($
) in the replacement string may cause the results to be different than if it were being treated as a literal replacement string. Dollar signs may be treated as references to captured subsequences as described above, and backslashes are used to escape literal characters in the replacement string.
As pointed out by isnot2bad in a comment, Matcher.quoteReplacement
may be useful here:
Returns a literal replacement String for the specified String. .. The String produced will match the sequence of characters in s treated as a literal sequence. Slashes (
\
) and dollar signs ($
) will be given no special meaning.
I had your code setup on jsFiddle to try diagnose the problem.
However, I don't seem to encounter your issue. Could you take a look and let us know?

The definitive answer (covering changes to jQuery api at version 1.6) has been given by Gnarf
This is all you need to do:
$((COUNTER++))
Here's an excerpt from Learning the bash Shell, 3rd Edition, pp. 147, 148:
bash arithmetic expressions are equivalent to their counterparts in the Java and C languages.[9] Precedence and associativity are the same as in C. Table 6-2 shows the arithmetic operators that are supported. Although some of these are (or contain) special characters, there is no need to backslash-escape them, because they are within the $((...)) syntax.
..........................
The ++ and - operators are useful when you want to increment or decrement a value by one.[11] They work the same as in Java and C, e.g., value++ increments value by 1. This is called post-increment; there is also a pre-increment: ++value. The difference becomes evident with an example:
$ i=0
$ echo $i
0
$ echo $((i++))
0
$ echo $i
1
$ echo $((++i))
2
$ echo $i
2
See http://www.safaribooksonline.com/a/learning-the-bash/7572399/
And even simpler using IN:
SELECT ads.*, location.county
FROM ads
LEFT JOIN location ON location.county = ads.county_id
WHERE ads.published = 1
AND ads.type = 13
AND ads.county_id IN (2,5,7,9)
It is possible and is deceptively easy:
bin\Debug
folder below the project file (.csproj).app.publish
folder (they are not needed), and the .pdb files unless you foresee debugging directly on your user's system (for example, by remote control)), and provide it to the users.An added advantage is that, as a ClickOnce application, it does not require administrative privileges to run (if your application follows the normal guidelines for which folders to use for application data, etc.).
As for .NET, you can check for the minimum required version of .NET being installed (or at all) in the application (most users will already have it installed) and present a dialog with a link to the download page on the Microsoft website (or point to one of your pages that could redirect to the Microsoft page - this makes it more robust if the Microsoft URL change). As it is a small utility, you could target .NET 2.0 to reduce the probability of a user to have to install .NET.
It works. We use this method during development and test to avoid having to constantly uninstall and install the application and still being quite close to how the final application will run.
In case you are using Java 8 and want to have a more Functional Programming approach, you can define a Function
that manages the control and then you can reuse it and apply()
whenever is needed.
Coming to practice, you can define the Function
as
Function<String, Boolean> isNotEmpty = s -> s != null && !"".equals(s)
Then, you can use it by simply calling the apply()
method as:
String emptyString = "";
isNotEmpty.apply(emptyString); // this will return false
String notEmptyString = "StackOverflow";
isNotEmpty.apply(notEmptyString); // this will return true
If you prefer, you can define a Function
that checks if the String
is empty and then negate it with !
.
In this case, the Function
will look like as :
Function<String, Boolean> isEmpty = s -> s == null || "".equals(s)
Then, you can use it by simply calling the apply()
method as:
String emptyString = "";
!isEmpty.apply(emptyString); // this will return false
String notEmptyString = "StackOverflow";
!isEmpty.apply(notEmptyString); // this will return true
I had a similar issue. I had installed PHPMailer version 1.72 which is not prepared to manage SSL connections. Upgrading to last version solved the problem.
A one liner shell script to remove a file if it already exist (based on Jindra Helcl's answer):
[ -f file ] && rm file
or with a variable:
#!/bin/bash
file="/path/to/file.ext"
[ -f $file ] && rm $file
There's something really simple that you might be overlooking after trying to center the window using either setLocationRelativeTo(null)
or setLocation(x,y)
and it ends up being a little off center.
Make sure that you use either one of these methods after calling pack()
because the you'll end up using the dimensions of the window itself to calculate where to place it on screen. Until pack()
is called, the dimensions aren't what you'd think thus throwing off the calculations to center the window. Hope this helps.
It was fixed when I removed settings.xml
from .m2 folder.
In case you use Razer product and install Razer Synapse software on your PC, it blocks the port 80 too.
It is not included in the netstat
command so I am not able to troubleshoot it. Since there are many services included within the software, I can't analyze which one that blocks the port. After uninstalling the Razer Synapse, I can start the Apache server again on Windows 10.
CSS has different pseudo selector by which you can achieve such effect. In your case you can use
:active : if you want background color only when the button is clicked and don't want to persist.
:focus: if you want background color untill the focus is on the button.
button:active{
background:olive;
}
and
button:focus{
background:olive;
}
P.S.: Please don't give the number in Id
attribute of html elements.
If your web server is running php5, I believe you must use php5_value
. This resolved the same error I received when using php_value
.
What about Regex.Replace solution?
myStr = Regex.Replace(myStr, "\s", "")

As you can see in the code of angular-JS ( https://github.com/angular/angular.js/blob/master/src/ng/filter/orderBy.js ) ng-repeat does not work with objects. Here is a hack with sortFunction.
http://jsfiddle.net/sunnycpp/qaK56/33/
<div ng-app='myApp'>
<div ng-controller="controller">
<ul>
<li ng-repeat="test in testData | orderBy:sortMe()">
Order = {{test.value.order}} -> Key={{test.key}} Name=:{{test.value.name}}
</li>
</ul>
</div>
</div>
myApp.controller('controller', ['$scope', function ($scope) {
var testData = {
a:{name:"CData", order: 2},
b:{name:"AData", order: 3},
c:{name:"BData", order: 1}
};
$scope.testData = _.map(testData, function(vValue, vKey) {
return { key:vKey, value:vValue };
}) ;
$scope.sortMe = function() {
return function(object) {
return object.value.order;
}
}
}]);
Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.
The easiest way to do it is to use the End
method, which is gives you the cell that you reach by pressing the end key and then a direction when you're on a cell (in this case B6). This won't give you what you expect if B6 or B7 is empty, though.
Dim start_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Range(start_cell, start_cell.End(xlDown)).Copy Range("[Workbook2.xlsx]Sheet1!A2")
If you can't use End
, then you would have to use a loop.
Dim start_cell As Range, end_cell As Range
Set start_cell = Range("[Workbook1.xlsx]Sheet1!B6")
Set end_cell = start_cell
Do Until IsEmpty(end_cell.Offset(1, 0))
Set end_cell = end_cell.Offset(1, 0)
Loop
Range(start_cell, end_cell).Copy Range("[Workbook2.xlsx]Sheet1!A2")
Simplified form:
Last week data:
SELECT id FROM tbl
WHERE
WEEK (date) = WEEK( current_date ) - 1 AND YEAR( date) = YEAR( current_date );
2 weeks ago data:
SELECT id FROM tbl
WHERE
WEEK (date) = WEEK( current_date ) - 2 AND YEAR( date) = YEAR( current_date );
SQL Fiddle
Short and sweet:
A hash table wraps up an array, lets call it internalArray
. Items are inserted into the array in this way:
let insert key value =
internalArray[hash(key) % internalArray.Length] <- (key, value)
//oversimplified for educational purposes
Sometimes two keys will hash to the same index in the array, and you want to keep both values. I like to store both values in the same index, which is simple to code by making internalArray
an array of linked lists:
let insert key value =
internalArray[hash(key) % internalArray.Length].AddLast(key, value)
So, if I wanted to retrieve an item out of my hash table, I could write:
let get key =
let linkedList = internalArray[hash(key) % internalArray.Length]
for (testKey, value) in linkedList
if (testKey = key) then return value
return null
Delete operations are just as simple to write. As you can tell, inserts, lookups, and removal from our array of linked lists is nearly O(1).
When our internalArray gets too full, maybe at around 85% capacity, we can resize the internal array and move all of the items from the old array into the new array.
Try this from different folder:
sudo tar -cvjSf folder.tar.bz2 folder/*
Talking about functional PHP, I have this more generic answer:
array_map(function($arr){
$ret = $arr;
$ret['value'] = $ret['url'];
unset($ret['url']);
return $ret;
}, $tag);
}
The usual answer to this is "use a DocumentListener
". However, I always find that interface cumbersome. Truthfully the interface is over-engineered. It has three methods, for insertion, removal, and replacement of text, when it only needs one method: replacement. (An insertion can be viewed as a replacement of no text with some text, and a removal can be viewed as a replacement of some text with no text.)
Usually all you want is to know is when the text in the box has changed, so a typical DocumentListener
implementation has the three methods calling one method.
Therefore I made the following utility method, which lets you use a simpler ChangeListener
rather than a DocumentListener
. (It uses Java 8's lambda syntax, but you can adapt it for old Java if needed.)
/**
* Installs a listener to receive notification when the text of any
* {@code JTextComponent} is changed. Internally, it installs a
* {@link DocumentListener} on the text component's {@link Document},
* and a {@link PropertyChangeListener} on the text component to detect
* if the {@code Document} itself is replaced.
*
* @param text any text component, such as a {@link JTextField}
* or {@link JTextArea}
* @param changeListener a listener to receieve {@link ChangeEvent}s
* when the text is changed; the source object for the events
* will be the text component
* @throws NullPointerException if either parameter is null
*/
public static void addChangeListener(JTextComponent text, ChangeListener changeListener) {
Objects.requireNonNull(text);
Objects.requireNonNull(changeListener);
DocumentListener dl = new DocumentListener() {
private int lastChange = 0, lastNotifiedChange = 0;
@Override
public void insertUpdate(DocumentEvent e) {
changedUpdate(e);
}
@Override
public void removeUpdate(DocumentEvent e) {
changedUpdate(e);
}
@Override
public void changedUpdate(DocumentEvent e) {
lastChange++;
SwingUtilities.invokeLater(() -> {
if (lastNotifiedChange != lastChange) {
lastNotifiedChange = lastChange;
changeListener.stateChanged(new ChangeEvent(text));
}
});
}
};
text.addPropertyChangeListener("document", (PropertyChangeEvent e) -> {
Document d1 = (Document)e.getOldValue();
Document d2 = (Document)e.getNewValue();
if (d1 != null) d1.removeDocumentListener(dl);
if (d2 != null) d2.addDocumentListener(dl);
dl.changedUpdate(null);
});
Document d = text.getDocument();
if (d != null) d.addDocumentListener(dl);
}
Unlike with adding a listener directly to the document, this handles the (uncommon) case that you install a new document object on a text component. Additionally, it works around the problem mentioned in Jean-Marc Astesana's answer, where the document sometimes fires more events than it needs to.
Anyway, this method lets you replace annoying code which looks like this:
someTextBox.getDocument().addDocumentListener(new DocumentListener() {
@Override
public void insertUpdate(DocumentEvent e) {
doSomething();
}
@Override
public void removeUpdate(DocumentEvent e) {
doSomething();
}
@Override
public void changedUpdate(DocumentEvent e) {
doSomething();
}
});
With:
addChangeListener(someTextBox, e -> doSomething());

Try this worked for me Add this dependency to your build.gradle File
compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
This is how I solved it. I forgot that sublist was a direct reference to the elements in the original list, so it makes sense why it wouldn't work.
ArrayList<Integer> inputA = new ArrayList<Integer>(input.subList(0, input.size()/2));
What have you tried? This should work.
h1 { font-size: 20pt; }
h2 { font-size: 16pt; }
For the ones not wanting to create an entrypoint script like me, you actually can start mysqld at build-time and then execute the mysql commands in your Dockerfile like so:
RUN mysqld_safe & until mysqladmin ping; do sleep 1; done && \
mysql -uroot -e "CREATE DATABASE somedb;" && \
mysql -uroot -e "CREATE USER 'someuser'@'localhost' IDENTIFIED BY 'somepassword';" && \
mysql -uroot -e "GRANT ALL PRIVILEGES ON somedb.* TO 'someuser'@'localhost';"
The key here is to send mysqld_safe to background with the single &
sign.

public class SecretKeyGenerator {
public static void main(String[] args) throws NoSuchAlgorithmException {

SecureRandom secureRandom = new SecureRandom();
int keyBitSize = 256;
keyGenerator.init(keyBitSize, secureRandom);
SecretKey secretKey = keyGenerator.generateKey();
System.out.println(Base64.getEncoder().encodeToString(secretKey.getEncoded()));
}

Very late to the thread, but a technique I've used, pre-Angular, is to take advantage of JSON and the flexibility of JS to dynamically reference collection keys, and use inalienable facts of the environment (host server name, current browser language, etc.) as inputs to selectively discriminate/prefer suffixed key names within a JSON data structure.
This provides not merely deploy-environment context (per OP) but any arbitrary context (such as language) to provide i18n or any other variance required simultaneously, and (ideally) within a single configuration manifest, without duplication, and readably obvious.
IN ABOUT 10 LINES VANILLA JS
Overly-simplified but classic example: An API endpoint base URL in a JSON-formatted properties file that varies per environment where (natch) the host server will also vary:
...
'svcs': {
'VER': '2.3',
'API@localhost': 'http://localhost:9090/',
'[email protected]': 'https://www.uat.productionwebsite.com:9090/res/',
'[email protected]': 'https://www.productionwebsite.com:9090/api/res/'
},
...
A key to the discrimination function is simply the server hostname in the request.
This, naturally, can be combined with an additional key based on the user's language settings:
...
'app': {
'NAME': 'Ferry Reservations',
'NAME@fr': 'Réservations de ferry',
'NAME@de': 'Fähren Reservierungen'
},
...
The scope of the discrimination/preference can be confined to individual keys (as above) where the "base" key is only overwritten if there's a matching key+suffix for the inputs to the function -- or an entire structure, and that structure itself recursively parsed for matching discrimination/preference suffixes:
'help': {
'BLURB': 'This pre-production environment is not supported. Contact Development Team with questions.',
'PHONE': '808-867-5309',
'EMAIL': '[email protected]'
},
'[email protected]': {
'BLURB': 'Please contact Customer Service Center',
'BLURB@fr': 'S\'il vous plaît communiquer avec notre Centre de service à la clientèle',
'BLURB@de': 'Bitte kontaktieren Sie unseren Kundendienst!!1!',
'PHONE': '1-800-CUS-TOMR',
'EMAIL': '[email protected]'
},
SO, if a visiting user to the production website has German (de) language preference setting, the above configuration would collapse to:
'help': {
'BLURB': 'Bitte kontaktieren Sie unseren Kundendienst!!1!',
'PHONE': '1-800-CUS-TOMR',
'EMAIL': '[email protected]'
},
What does such a magical preference/discrimination JSON-rewriting function look like? Not much:
// prefer(object,suffix|[suffixes]) by/par/durch storsoc
// prefer({ a: 'apple', a@env: 'banana', b: 'carrot' },'env') -> { a: 'banana', b: 'carrot' }
function prefer(o,sufs) {
for (var key in o) {
if (!o.hasOwnProperty(key)) continue; // skip non-instance props
if(key.split('@')[1]) { // suffixed!
// replace root prop with the suffixed prop if among prefs
if(o[key] && sufs.indexOf(key.split('@')[1]) > -1) o[key.split('@')[0]] = JSON.parse(JSON.stringify(o[key]));
// and nuke the suffixed prop to tidy up
delete o[key];
// continue with root key ...
key = key.split('@')[0];
}
// ... in case it's a collection itself, recurse it!
if(o[key] && typeof o[key] === 'object') prefer(o[key],sufs);
};
};
In our implementations, which include Angular and pre-Angular websites, we simply bootstrap the configuration well ahead of other resource calls by placing the JSON within a self-executing JS closure, including the prefer() function, and fed basic properties of hostname and language-code (and accepts any additional arbitrary suffixes you might need):
(function(prefs){ var props = {
'svcs': {
'VER': '2.3',
'API@localhost': 'http://localhost:9090/',
'[email protected]': 'https://www.uat.productionwebsite.com:9090/res/',
'[email protected]': 'https://www.productionwebsite.com:9090/api/res/'
},
...
/* yadda yadda moar JSON und bisque */
function prefer(o,sufs) {
// body of prefer function, broken for e.g.
};
// convert string and comma-separated-string to array .. and process it
prefs = [].concat( ( prefs.split ? prefs.split(',') : prefs ) || []);
prefer(props,prefs);
window.app_props = JSON.parse(JSON.stringify(props));
})([location.hostname, ((window.navigator.userLanguage || window.navigator.language).split('-')[0]) ] );
A pre-Angular site would now have a collapsed (no @ suffixed keys) window.app_props to refer to.
An Angular site, as a bootstrap/init step, simply copies the dead-dropped props object into $rootScope, and (optionally) destroys it from global/window scope
app.constant('props',angular.copy(window.app_props || {})).run( function ($rootScope,props) { $rootScope.props = props; delete window.app_props;} );
to be subsequently injected into controllers:
app.controller('CtrlApp',function($log,props){ ... } );
or referred to from bindings in views:
<span>{{ props.help.blurb }} {{ props.help.email }}</span>
Caveats? The @ character is not valid JS/JSON variable/key naming, but so far accepted. If that's a deal-breaker, substitute for any convention you like, such as "__" (double underscore) as long as you stick to it.
The technique could be applied server-side, ported to Java or C# but your efficiency/compactness may vary.
Alternately, the function/convention could be part of your front-end compile script, so that the full gory all-environment/all-language JSON is never transmitted over the wire.
UPDATE
We've evolved usage of this technique to allow multiple suffixes to a key, to avoid being forced to use collections (you still can, as deeply as you want), and as well to honor the order of the preferred suffixes.
Example (also see working jsFiddle):
var o = { 'a':'apple', 'a@dev':'apple-dev', 'a@fr':'pomme',
'b':'banana', 'b@fr':'banane', 'b@dev&fr':'banane-dev',
'c':{ 'o':'c-dot-oh', 'o@fr':'c-point-oh' }, 'c@dev': { 'o':'c-dot-oh-dev', 'o@fr':'c-point-oh-dev' } };
/*1*/ prefer(o,'dev'); // { a:'apple-dev', b:'banana', c:{o:'c-dot-oh-dev'} }
/*2*/ prefer(o,'fr'); // { a:'pomme', b:'banane', c:{o:'c-point-oh'} }
/*3*/ prefer(o,'dev,fr'); // { a:'apple-dev', b:'banane-dev', c:{o:'c-point-oh-dev'} }
/*4*/ prefer(o,['fr','dev']); // { a:'pomme', b:'banane-dev', c:{o:'c-point-oh-dev'} }
/*5*/ prefer(o); // { a:'apple', b:'banana', c:{o:'c-dot-oh'} }
1/2 (basic usage) prefers '@dev' keys, discards all other suffixed keys
3 prefers '@dev' over '@fr', prefers '@dev&fr' over all others
4 (same as 3 but prefers '@fr' over '@dev')
5 no preferred suffixes, drops ALL suffixed properties
It accomplishes this by scoring each suffixed property and promoting the value of a suffixed property to the non-suffixed property when iterating over the properties and finding a higher-scored suffix.
Some efficiencies in this version, including removing dependence on JSON to deep-copy, and only recursing into objects that survive the scoring round at their depth:
function prefer(obj,suf) {
function pr(o,s) {
for (var p in o) {
if (!o.hasOwnProperty(p) || !p.split('@')[1] || p.split('@@')[1] ) continue; // ignore: proto-prop OR not-suffixed OR temp prop score
var b = p.split('@')[0]; // base prop name
if(!!!o['@@'+b]) o['@@'+b] = 0; // +score placeholder
var ps = p.split('@')[1].split('&'); // array of property suffixes
var sc = 0; var v = 0; // reset (running)score and value
while(ps.length) {
// suffix value: index(of found suffix in prefs)^10
v = Math.floor(Math.pow(10,s.indexOf(ps.pop())));
if(!v) { sc = 0; break; } // found suf NOT in prefs, zero score (delete later)
sc += v;
}
if(sc > o['@@'+b]) { o['@@'+b] = sc; o[b] = o[p]; } // hi-score! promote to base prop
delete o[p];
}
for (var p in o) if(p.split('@@')[1]) delete o[p]; // remove scores
for (var p in o) if(typeof o[p] === 'object') pr(o[p],s); // recurse surviving objs
}
if( typeof obj !== 'object' ) return; // validate
suf = ( (suf || suf === 0 ) && ( suf.length || suf === parseFloat(suf) ) ? suf.toString().split(',') : []); // array|string|number|comma-separated-string -> array-of-strings
pr(obj,suf.reverse());
}
This isn't an answer. I was struggling but then realized that my install was trying to connect to internet to download dependencies.
So, I downloaded and installed dependencies first and then installed with below command. It worked
python -m pip install filename.tar.gz
Here is a simple script that you can use. I like using the non-standard module File::chdir
to handle managing cd
operations, so to use this script as-is you will need to install it (sudo cpan File::chdir
).
#!/usr/bin/perl
use strict;
use warnings;
use File::Copy;
use File::chdir; # allows cd-ing by use of $CWD, much easier but needs CPAN module
die "Usage: $0 dir prefix" unless (@ARGV >= 2);
my ($dir, $pre) = @ARGV;
opendir(my $dir_handle, $dir) or die "Cannot open directory $dir";
my @files = readdir($dir_handle);
close($dir_handle);
$CWD = $dir; # cd to the directory, needs File::chdir
foreach my $file (@files) {
next if ($file =~ /^\.+$/); # avoid folders . and ..
next if ($0 =~ /$file/); # avoid moving this script if it is in the directory
move($file, $pre . $file) or warn "Cannot rename file $file: $!";
}
If you just want to do it once, without adding a shortcut, you can always type
<prefix>
:
kill-window
<enter>
Use the Socket()
constructor, and connect(SocketAddress endpoint, int timeout)
method instead.
In your case it would look something like:
Socket socket = new Socket();
socket.connect(new InetSocketAddress(ipAddress, port), 1000);
Quoting from the documentation
connect
public void connect(SocketAddress endpoint, int timeout) throws IOException
Connects this socket to the server with a specified timeout value. A timeout of zero is interpreted as an infinite timeout. The connection will then block until established or an error occurs.
Parameters:
endpoint
- the SocketAddress
timeout
- the timeout value to be used in milliseconds.Throws:
IOException
- if an error occurs during the connection
SocketTimeoutException
- if timeout expires before connecting
IllegalBlockingModeException
- if this socket has an associated channel, and the channel is in non-blocking mode
IllegalArgumentException
- if endpoint is null or is a SocketAddress subclass not supported by this socketSince: 1.4
ContactNumbers = new List<ContactNumber>();
If you want it to be passed in, just take
public Human(List<ContactNumber> numbers)
{
ContactNumbers = numbers;
}

@peterSO has correct answer. I am adding more examples here:
package main
import (
"fmt"
strings "strings"
)
func main() {
test := "\t pdftk 2.0.2 \n"
result := strings.TrimSpace(test)
fmt.Printf("Length of %q is %d\n", test, len(test))
fmt.Printf("Length of %q is %d\n\n", result, len(result))
test = "\n\r pdftk 2.0.2 \n\r"
result = strings.TrimSpace(test)
fmt.Printf("Length of %q is %d\n", test, len(test))
fmt.Printf("Length of %q is %d\n\n", result, len(result))
test = "\n\r\n\r pdftk 2.0.2 \n\r\n\r"
result = strings.TrimSpace(test)
fmt.Printf("Length of %q is %d\n", test, len(test))
fmt.Printf("Length of %q is %d\n\n", result, len(result))
test = "\r pdftk 2.0.2 \r"
result = strings.TrimSpace(test)
fmt.Printf("Length of %q is %d\n", test, len(test))
fmt.Printf("Length of %q is %d\n\n", result, len(result))
}
You can find this in Go lang playground too.
I prefer option two because it clearly shows the list item as the possessor of that nested list. I would always lean towards semantically sound HTML.
You can use this (I didn't try this yet, but I hope this works):
if(startService(someIntent) != null) {
Toast.makeText(getBaseContext(), "Service is already running", Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(getBaseContext(), "There is no service running, starting service..", Toast.LENGTH_SHORT).show();
}
The startService method returns a ComponentName object if there is an already running service. If not, null will be returned.
See public abstract ComponentName startService (Intent service).
This is not like checking I think, because it's starting the service, so you can add stopService(someIntent);
under the code.
It is most likely due to a cross-origin request, but it may not be. For me, I had been debugging an API and had set the Access-Control-Allow-Origin
to *
, but it appears that recent versions of Chrome are requiring an extra header. Try prepending the following to your file if you are using PHP:
header("Access-Control-Allow-Origin: *");
header("Access-Control-Allow-Headers: Origin, X-Requested-With, Content-Type, Accept");
Make sure that you haven't already used header
in another file, or you will get a nasty error. See the docs for more.
I got this error when I did a Response.Redirect
after a successful login of the user.
I fixed it by doing a FormsAuthentication.RedirectFromLoginPage
instead.
import vs. include
The primary purpose of an import is to import a namespace. A more common use of the XSD import statement is to import a namespace which appears in another file. You might be gathering the namespace information from the file, but don't forget that it's the namespace that you're importing, not the file (don't confuse an import
statement with an include
statement).
Another area of confusion is how to specify the location or path of the included .xsd
file: An XSD import statement has an optional attribute named schemaLocation
but it is not necessary if the namespace of the import statement is at the same location (in the same file) as the import statement itself.
When you do chose to use an external .xsd
file for your WSDL, the schemaLocation
attribute becomes necessary. Be very sure that the namespace you use in the import statement is the same as the targetNamespace of the schema you are importing. That is, all 3 occurrences must be identical:
WSDL:
xs:import namespace="urn:listing3" schemaLocation="listing3.xsd"/>
XSD:
<xsd:schema targetNamespace="urn:listing3"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
Another approach to letting know the WSDL about the XSD is through Maven's pom.xml:
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>xmlbeans-maven-plugin</artifactId>
<executions>
<execution>
<id>generate-sources-xmlbeans</id>
<phase>generate-sources</phase>
<goals>
<goal>xmlbeans</goal>
</goals>
</execution>
</executions>
<version>2.3.3</version>
<inherited>true</inherited>
<configuration>
<schemaDirectory>${basedir}/src/main/xsd</schemaDirectory>
</configuration>
</plugin>
You can read more on this in this great IBM article. It has typos such as xsd:import
instead of xs:import
but otherwise it's fine.
Thanks for the info, think I see the problem. This is a bug in hive-go
that only shows up when you add a host. The last lines of it are:
app.listen(3001);
console.log("... port %d in %s mode", app.address().port, app.settings.env);
When you add the host on the first line, it is crashing when it calls app.address().port
.
The problem is the potentially asynchronous nature of .listen()
. Really it should be doing that console.log
call inside a callback passed to listen. When you add the host, it tries to do a DNS lookup, which is async. So when that line tries to fetch the address, there isn't one yet because the DNS request is running, so it crashes.
Try this:
app.listen(3001, 'localhost', function() {
console.log("... port %d in %s mode", app.address().port, app.settings.env);
});
this datepicker is an excellent solution. datepickers are a must if you want to avoid code injection.

I'm a eternal newbie in regex but I'll try explain this one
(\w*(Hex): w*) : Find text in line where string contains "Hex: "
(.*?) This is the second captured text and means everything after

conversion specifiers behave the same with fprintf
but behave differently for fscanf
.
As some other wrote in their answer, the idiomatic way to print an int
is using d
conversion specifier.
Regarding i
specifier and fprintf
, C99 Rationale says that:
The %i conversion specifier was added in C89 for programmer convenience to provide symmetry with fscanf’s %i conversion specifier, even though it has exactly the same meaning as the %d conversion specifier when used with fprintf.
Output of git push
when pushing a new branch
> git checkout -b new_branch
Switched to a new branch 'new_branch'
> git push
fatal: The current branch new_branch has no upstream branch.
To push the current branch and set the remote as upstream, use
git push --set-upstream origin new_branch
A simple git push
assumes that there already exists a remote branch that the current local branch is tracking. If no such remote branch exists, and you want to create it, you must specify that using the -u
(short form of --set-upstream
) flag.
Why this is so? I guess the implementers felt that creating a branch on the remote is such a major action that it should be hard to do it by mistake. git push
is something you do all the time.
"Isn't a branch a new change to be pushed by default?" I would say that "a change" in Git is a commit. A branch is a pointer to a commit. To me it makes more sense to think of a push as something that pushes commits over to the other repositories. Which commits are pushed is determined by what branch you are on and the tracking relationship of that branch to branches on the remote.
You can read more about tracking branches in the Remote Branches chapter of the Pro Git book.

return Scaffold(

body:
SELECT *
FROM tbl
WHERE id = 1
ORDER BY signin DESC
LIMIT 1;
The obvious index would be on (id)
, or a multicolumn index on (id, signin DESC)
.
Conveniently for the case, MySQL sorts NULL
values last in descending order. That's what you typically want if there can be NULL
values: the row with the latest not-null signin
.
To get NULL
values first:
ORDER BY signin IS NOT NULL, signin DESC
You may want to append more expressions to ORDER BY
to get a deterministic pick from (potentially) multiple rows with NULL
.
The same applies without NULL
if signin
is not defined UNIQUE
.

While you can use rand(42-10) + 10
to get a random number between 10
and 42
(where 10 is inclusive and 42 exclusive), there's a better way since Ruby 1.9.3, where you are able to call:
rand(10...42) # => 13
Available for all versions of Ruby by requiring my backports
gem.
Ruby 1.9.2 also introduced the Random
class so you can create your own random number generator objects and has a nice API:
r = Random.new
r.rand(10...42) # => 22
r.bytes(3) # => "rnd"
The Random
class itself acts as a random generator, so you call directly:
Random.rand(10...42) # => same as rand(10...42)
Notes on Random.new
In most cases, the simplest is to use rand
or Random.rand
. Creating a new random generator each time you want a random number is a really bad idea. If you do this, you will get the random properties of the initial seeding algorithm which are atrocious compared to the properties of the random generator itself.
If you use Random.new
, you should thus call it as rarely as possible, for example once as MyApp::Random = Random.new
and use it everywhere else.
The cases where Random.new
is helpful are the following:
rand
/Random.rand

objects can marshalled)The use of levels is really up tp you. You need to decide what is severe in your application, what is a warning and what is just information. You need to split your logging so that your users can easily set up a level of logging that doesn't kill the system with excessing IO but which will report serious errors so you can fix them.
Here is how you do in Eloquent
$users = User::whereIn('id', array(1, 2, 3))->get();
And if you are using Query builder then :
$users = DB::table('users')->whereIn('id', array(1, 2, 3))->get();
It fires in this order.

When you're analyzing code, you have to analyse it line by line, counting every operation/recognizing time complexity, in the end, you have to sum it to get whole picture.
For example, you can have one simple loop with linear complexity, but later in that same program you can have a triple loop that has cubic complexity, so your program will have cubic complexity. Function order of growth comes into play right here.
Let's look at what are possibilities for time complexity of an algorithm, you can see order of growth I mentioned above:
Constant time has an order of growth 1
, for example: a = b + c
.
Logarithmic time has an order of growth LogN
, it usually occurs
when you're dividing something in half (binary search, trees, even loops), or multiplying something in same way.
Linear, order of growth is N
, for example
int p = 0;
for (int i = 1; i < N; i++)
p = p + 2;
Linearithmic, order of growth is n*logN
, usually occurs in divide and conquer algorithms.
Cubic, order of growth N^3
, classic example is a triple loop where you check all triplets:
int x = 0;
for (int i = 0; i < N; i++)
for (int j = 0; j < N; j++)
for (int k = 0; k < N; k++)
x = x + 2
Exponential, order of growth 2^N
, usually occurs when you do exhaustive search, for example check subsets of some set.

Update 2nd table data in 1st table need to Inner join before SET :

UINavigationItem *item = [[UINavigationItem alloc] initWithTitle:@"Title"];
item.rightBarButtonItem = rightButton;
item.hidesBackButton = YES;
[bar pushNavigationItem:item animated:NO];
But normally you would have a NavigationController
, enabling you to write:
UIBarButtonItem *rightButton = [[UIBarButtonItem alloc] initWithTitle:@"Done"
style:UIBarButtonItemStyleDone target:nil action:nil];
self.navigationItem.rightBarButtonItem = rightButton;
Try this -
select * from table where id in (3,4) or [name] in ('andy','paul');

Just create a button element with jQuery, and add the event handler when you create it :
var div = $('<div />', {'data-role' : 'fieldcontain'}),
btn = $('<input />', {
type : 'button',
value : 'Dynamic Button',
id : 'btn_a',
on : {
click: function() {
alert ( this.value );
}
}
});
div.append(btn).appendTo( $('#pg_menu_content').empty() );
What you're basically doing here is relying on Date#toString()
which already has a fixed pattern. To convert a Java Date
object into another human readable String pattern, you need SimpleDateFormat#format()
.
private String modifyDateLayout(String inputDate) throws ParseException{
Date date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss z").parse(inputDate);
return new SimpleDateFormat("dd.MM.yyyy HH:mm:ss").format(date);
}
By the way, the "unparseable date" exception can here only be thrown by SimpleDateFormat#parse()
. This means that the inputDate
isn't in the expected pattern "yyyy-MM-dd HH:mm:ss z"
. You'll probably need to modify the pattern to match the inputDate
's actual pattern.
Update: Okay, I did a test:
public static void main(String[] args) throws Exception {
String inputDate = "2010-01-04 01:32:27 UTC";
String newDate = new Test().modifyDateLayout(inputDate);
System.out.println(newDate);
}
This correctly prints:
03.01.2010 21:32:27
(I'm on GMT-4)
Update 2: as per your edit, you really got a ParseException
on that. The most suspicious part would then be the timezone of UTC
. Is this actually known at your Java environment? What Java version and what OS version are you using? Check TimeZone.getAvailableIDs()
. There must be a UTC
in between.

from StringIO import StringIO
else:
from io import StringIO
import pandas as pd
TESTDATA = StringIO("""col1;col2;col3
1;4.4;99

Actually what Luis proposed did not work for me. I had to figure out another way. This is what helped me. Might help you too. Links:
*.getEncoded(): https://docs.oracle.com/javase/7/docs/api/java/security/Key.html

Decoder information: https://docs.oracle.com/javase/8/docs/api/java/util/Base64.Decoder.html
Code snippets: For encoding:
String temp = new String(Base64.getEncoder().encode(key.getEncoded()));
For decoding:
byte[] encodedKey = Base64.getDecoder().decode(temp);
SecretKey originalKey = new SecretKeySpec(encodedKey, 0, encodedKey.length, "DES");
I was able to customize the hrTag by editing the inline styling as such:
<div class="row"> <!-- You can also position the row if need be. -->
<div class="col-md-12 col-lg-12"><!-- set width of column I wanted mine to stretch most of the screen-->
<hr style="min-width:85%; background-color:#a1a1a1 !important; height:1px;"/>
</div>
</div>
The hrTag is now thicker and more visible; it's also a darker gray color. The bootstrap code is actually very flexible. As the snippet demonstrates above, you can use inline styling or your own custom code. Hope this helps someone.
In a controller action, you could just do:
public function someAction(Request $request)
{
$routeName = $request->route()->getName();
}
$request
here is resolved by Laravel's service container.
getName()
returns the route name for named routes only, null
otherwise (but you could still explore the \Illuminate\Routing\Route
object for something else of interest).
In other words, you should have your route defined like this to have "nameOfMyRoute" returned:
Route::get('my/some-action', [
'as' => 'nameOfMyRoute',
'uses' => 'MyController@someAction'
]);
According to the documentation for 3.4, It is preferred to use attributes with attr()
method.
$('<div></div>').attr(
{
id: 'some dynanmic|static id',
"class": 'some dynanmic|static class'
}
).click(function() {
$( "span", this ).addClass( "bar" ); // example from the docs
});

Had the same problem with base64. For anyone in the future with the same problem:
url = "data:image/png;base64,iVBORw0KGgoAAAAAAAAyCAYAAAAUYybjAAAgAElE...";
This would work executed from console, but not from within a script:
$img.css("background-image", "url('" + url + "')");
But after playing with it a bit, I came up with this:
var img = new Image();
img.src = url;
$img.css("background-image", "url('" + img.src + "')");
No idea why it works with a proxy image, but it does. Tested on Firefox Dev 37 and Chrome 40.
Hope it helps someone.
EDIT
Investigated a little bit further. It appears that sometimes base64 encoding (at least in my case) breaks with CSS because of line breaks present in the encoded value (in my case value was generated dynamically by ActionScript).
Simply using e.g.:
$img.css("background-image", "url('" + url.replace(/(\r\n|\n|\r)/gm, "") + "')");
works too, and even seems to be faster by a few ms than using a proxy image.

1:
what are the Grant Tables?
The MySQL system database includes several grant tables that contain information about user accounts and the privileges held by them.
clari?cation: in MySQL, there are some inbuilt databases , one of them is "mysql" , all the tables on "mysql" database have been called as grant tables
2:
note that if you perform:
UPDATE a_grant_table SET password=PASSWORD('1234') WHERE test_col = 'test_val';
and refresh phpMyAdmin , you'll realize that your password has been changed on that table but even now if you perform:
mysql -u someuser -p
your access will be denied by your new password until you perform :
FLUSH PRIVILEGES;
if you have more files in my case i have 7000 image files when i try to add them from project's route folder it hasn't added them but when i go to the image folder everything is ok. Go through the target folder and command like abows

Take a look at ISO 11179-5: Naming and identification principles You can get it here: http://metadata-standards.org/11179/#11179-5

The reason you are getting the unexpected result is that hist(...)
calculates the distribution from a numeric vector. In your code, table(animalFactor)
behaves like a numeric vector with three elements: 1, 3, 7. So hist(...)
plots the number of 1's (1), the number of 3's (1), and the number of 7's (1). @Roland's solution is the simplest.
Here's a way to do this using ggplot
:
library(ggplot2)
ggp <- ggplot(data.frame(animals),aes(x=animals))
# counts
ggp + geom_histogram(fill="lightgreen")
# proportion
ggp + geom_histogram(fill="lightblue",aes(y=..count../sum(..count..)))
You would get precisely the same result using animalFactor
instead of animals
in the code above.
To totally steal from Bill answer you can make an extension method and use some syntactic sugar to help you out.
Create a class file, StringExtensions.cs
Content:
public static class StringExt
{
public static bool IsNumeric(this string text)
{
double test;
return double.TryParse(text, out test);
}
}
EDIT: This is for updated C# 7 syntax. Declaring out parameter in-line.
public static class StringExt
{
public static bool IsNumeric(this string text) => double.TryParse(text, out _);
}
Call method like such:
var text = "I am not a number";
text.IsNumeric() //<--- returns false
It is simpler just to run an exact copy like below to put the copy in as the last sheet
Sub Test()
Dim ws1 As Worksheet
Set ws1 = ThisWorkbook.Worksheets("Master")
ws1.Copy ThisWorkbook.Sheets(Sheets.Count)
End Sub
git submodule update --recursive
You will also probably want to use the --init option which will make it initialize any uninitialized submodules:
git submodule update --init --recursive
Note: in some older versions of Git, if you use the --init
option, already-initialized submodules may not be updated. In that case, you should also run the command without --init
option.
Use env
.
For example, env FOO=BAR command
. Note that the environment variables will be restored/unchanged again when command
finishes executing.
Just be careful about about shell substitution happening, i.e. if you want to reference $FOO
explicitly on the same command line, you may need to escape it so that your shell interpreter doesn't perform the substitution before it runs env
.
$ export FOO=BAR
$ env FOO=FUBAR bash -c 'echo $FOO'
FUBAR
$ echo $FOO
BAR
@P-A's solution partially works for me. Detail my findings below:
1) The first code snippet is incorrect, see below:
<activity
...
<intent-filter>
==> <action android:name="android.intent.action.MAIN" /> <== This line shouldn't be deleted, otherwise will have compile error
<category android:name="android.intent.category.LAUNCHER" /> //DELETE THIS LINE
</intent-filter>
</activity>
2) Should use following code to disable all icons before enabling another one, otherwise it will add a new icon, instead of replacing it.
getPackageManager().setComponentEnabledSetting(

BUT, if you use code above, then shortcut on homescreen will be removed! And it won't be automatically added back. You might be able to programmatically add icon back, but it probably won't stay in the same position as before.
3) Note that the icon won't get changed immediately, it might take several seconds. If you click it right after changing, you might get an error saying: "App isn't installed".
So, IMHO this solution is only suitable for changing icon in app launcher only, not for shortcuts (i.e. the icon on homescreen)
I use @gnarf's method, though I fall back on document.writeln
ing a <script>
tag for IE<7 as I couldn't get DOM creation to work reliably in IE6 (and TBH didn't care enough to put much effort into it). The core of my code is:
if (horus.script.broken) {
document.writeln('<script type="text/javascript" src="'+script+'"></script>');
horus.script.loaded(script);
} else {
var s=document.createElement('script');
s.type='text/javascript';
s.src=script;
s.async=true;
if (horus.brokenDOM){
s.onreadystatechange=
function () {
if (this.readyState=='loaded' || this.readyState=='complete'){
horus.script.loaded(script);
}
}
}else{
s.onload=function () { horus.script.loaded(script) };
}
document.head.appendChild(s);
}
where horus.script.loaded()
notes that the javascript file is loaded, and calls any pending uncalled routines (saved by autoloader code).
You can get access to the WhatsApp data base located on the SD card only as a root user I think. if you open "\data\data\com.whatsapp" you will see that "databases" is linked to "\firstboot\sqlite\com.whatsapp\"
Caution - remember to always include the "quotes" - at least on Chrome, target=_blank
(no quotes) is NOT THE SAME as target="_blank"
(with quotes).
The latter opens each link in a new tab/window. The former (missing quotes) opens the first link you click in one new tab/window, then overwrites that same tab/window with each subsequent link you click (that's named also with the missing quotes).
This is the command to use to tell Gradle to upgrade the wrapper such that it will grab the distribution versions of libraries that includes source code:
./gradlew wrapper --gradle-version <version> --distribution-type all
Specifying the distribution-type with "all" will make sure Gradle downloads source files for use by your development environment.
Pros:
Cons:
Please comment or provide another answer if you know of any command line option to tell Gradle not to download sources on a build server.
I think a lot of folks are looking for a footer on the bottom that scrolls instead of being fixed, called a sticky footer. Fixed footers will cover body content when the height is too short. You have to set the html, body, and page container to a height of 100%, set your footer to absolute position bottom. Your page content container needs a relative position for this to work. Your footer has a negative margin equal to height of footer minus bottom margin of page content. See the example page I posted.
Example with notes: http://markbokil.com/code/bottomfooter/
Tip for 1 website resizing the height. But you can change to 2 websites.
Here is my code to resize an iframe with an external website. You need insert a code into the parent (with iframe code) page and in the external website as well, so, this won't work with you don't have access to edit the external website.
Local:
<IFRAME STYLE="width:100%;height:1px" SRC="http://www.remote-site.com/" FRAMEBORDER="no" BORDER="0" SCROLLING="no" ID="estframe"></IFRAME>
<SCRIPT>
var eventMethod = window.addEventListener ? "addEventListener" : "attachEvent";
var eventer = window[eventMethod];
var messageEvent = eventMethod == "attachEvent" ? "onmessage" : "message";
eventer(messageEvent,function(e) {
if (e.data.substring(0,3)=='frm') document.getElementById('estframe').style.height = e.data.substring(3) + 'px';
},false);
</SCRIPT>
You need this "frm" prefix to avoid problems with other embeded codes like Twitter or Facebook plugins. If you have a plain page, you can remove the "if" and the "frm" prefix on both pages (script and onload).
Remote:
You need jQuery to accomplish about "real" page height. I cannot realize how to do with pure JavaScript since you'll have problem when resize the height down (higher to lower height) using body.scrollHeight or related. For some reason, it will return always the biggest height (pre-redimensioned).
<BODY onload="parent.postMessage('frm'+$('#master').height(),'*')" STYLE="margin:0">
<SCRIPT SRC="path-to-jquery/jquery.min.js"></SCRIPT>
<DIV ID="master">
your content
</DIV>
So, parent page (iframe) has a 1px default height. The script inserts a "wait for message/event" from the iframe. When a message (post message) is received and the first 3 chars are "frm" (to avoid the mentioned problem), will get the number from 4th position and set the iframe height (style), including 'px' unit.
The external site (loaded in the iframe) will "send a message" to the parent (opener) with the "frm" and the height of the main div (in this case id "master"). The "*" in postmessage means "any source".
Hope this helps. Sorry for my english.
Can't upvote so I'll repost @jfs comment cause I think it should be more visible.
@AnneTheAgile: shell=True is not required. Moreover you should not use it unless it is necessary (see @ valid's comment). You should pass each command-line argument as a separate list item instead e.g., use ['command', 'arg 1', 'arg 2'] instead of "command 'arg 1' 'arg 2'". – jfs Mar 3 '15 at 10:02
Like this:
>>>mystr = "abcdefghijkl"
>>>mystr[-4:]
'ijkl'
This slices the string's last 4 characters. The -4 starts the range from the string's end. A modified expression with [:-4]
removes the same 4 characters from the end of the string:
>>>mystr[:-4]
'abcdefgh'
For more information on slicing see this Stack Overflow answer.
Remember that the "folders/groups" you make in xcode, those which are yellowish are not reflected as real folders in your iPhone app. They are just there to structure your XCode project. You can nest as many yellow group as you want and they still only serve the purpose of organizing code in XCode.
Make a folder outside of XCode then drag it over, and select "Create folder references for any added folders" instead of "Create groups for any added folders" in the popup.
You can easily simulate a click on an element, but a click on a <select>
won’t open up the dropdown.
Using multiple selects can be problematic. Perhaps you should consider radio buttons inside a container element which you can expand and contract as needed.
If I understood your problem correctly, $(this).parents('.box').children('.something1')
Is this what you are looking for?
EDIT: Bootstrap 3.3.4 has solved this problem (and other modal issues) so if you can update your bootstrap CSS and JS that would be the best solution. If you can't update the solution below will still work and essentially does the same thing as bootstrap 3.3.4 (recalculate and apply padding).
As Bass Jobsen pointed out, newer versions of Bootstrap have the z-index solved. The modal-open class and padding-right were still problems for me but this scripts inspired by Yermo Lamers solution solves it. Just drop it in your JS file and enjoy.
$(document).on('hide.bs.modal', '.modal', function (event) {
var padding_right = 0;
$.each($('.modal'), function(){
if($(this).hasClass('in') && $(this).modal().data('bs.modal').scrollbarWidth > padding_right) {
padding_right = $(this).modal().data('bs.modal').scrollbarWidth
}
});
$('body').data('padding_right', padding_right + 'px');
});
$(document).on('hidden.bs.modal', '.modal', function (event) {
$('body').data('open_modals', $('body').data('open_modals') - 1);
if($('body').data('open_modals') > 0) {
$('body').addClass('modal-open');
$('body').css('padding-right', $('body').data('padding_right'));
}
});
$(document).on('shown.bs.modal', '.modal', function (event) {
if (typeof($('body').data('open_modals')) == 'undefined') {
$('body').data('open_modals', 0);
}
$('body').data('open_modals', $('body').data('open_modals') + 1);
$('body').css('padding-right', (parseInt($('body').css('padding-right')) / $('body').data('open_modals') + 'px'));
});
This calls exactly for the using the Maven JAR Plugin
For example, if you want to exclude everything under src/test/resources/
from the final jar, put this:
<build>
<plugins>
<!-- configure JAR build -->
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.1</version>
<configuration>
<excludes>
<exclude>src/test/resources/**</exclude>
</excludes>
</configuration>
</plugin>
...
Files under src/test/resources/
will still be available on class-path, they just won't be in resulting JAR.
Simply run whatever returned in step one would fix the issue.
The right and standard way to do it is using classList
. It is now widely supported in the latest version of most modern browsers:
ELEMENT.classList.remove("CLASS_NAME");
remove.onclick = () => {_x000D_
const el = document.querySelector('#el');_x000D_
if (el.classList.contains("red")) {_x000D_
el.classList.remove("red");_x000D_
_x000D_
}_x000D_
}
_x000D_
.red {_x000D_
background: red_x000D_
}
_x000D_
<div id='el' class="red"> Test</div>_x000D_
<button id='remove'>Remove Class</button>
_x000D_
Documentation: https://developer.mozilla.org/en/DOM/element.classList
In an ideal case, you would like to test for all three values, null, "" or empty(field doesn't exist in the record)
You can do the following.
db.users.find({$and: [{"name" : {$nin: ["", null]}}, {"name" : {$exists: true}}]})
System.out.println(new String(new byte[]{ (byte)0x63 }, "US-ASCII"));
Note especially that converting bytes to Strings always involves an encoding. If you do not specify it, you'll be using the platform default encoding, which means the code can break when running in different environments.

I would like to include this repo How-to-Make-a-Computer-Operating-System by Samy Pesse. Is a work-in-progress. Very interesting.
I will quickly complement for cases where the header contains emojis, in that case it is simpler to just remove the emoji in the link of the reference. For example
# ? Title 2
....
[Take me to title 2](#-title-2)
There are some cases where this does not work for a weird reason, for example here in setup. The solution in that case is to include the whole code for the emoji as well.
For Fedora (tested for Fedora 23/24) run

Try to use
ng g component plainsight/some-name.component.ts
Or try it manually, if you feel more comfortable.
try this:
Dim ws as Worksheet
Set ws = Thisworkbook.Sheets("Sheet2")
With ws
.Range("E2").Formula = "=VLOOKUP(D2,Sheet1!$A:$C,1,0)"
End With
End Sub
This just the simplified version of what you want.
No need to use Application
if you will just output the answer in the Range("E2")
.
If you want to stick with your logic, declare the variables.
See below for example.
Sub Test()
Dim rng As Range
Dim ws1, ws2 As Worksheet
Dim MyStringVar1 As String
Set ws1 = ThisWorkbook.Sheets("Sheet1")
Set ws2 = ThisWorkbook.Sheets("Sheet2")
Set rng = ws2.Range("D2")
With ws2
On Error Resume Next 'add this because if value is not found, vlookup fails, you get 1004
MyStringVar1 = Application.WorksheetFunction.VLookup(rng, ws1.Range("A1:C65536").Value, 1, False)
On Error GoTo 0
If MyStringVar1 = "" Then MsgBox "Item not found" Else MsgBox MyStringVar1
End With
End Sub
Hope this get's you started.
On the Form Move Event add this:
private void Frm_Move (object sender, EventArgs e)
{
Top = 0; Left = 0;
Size = new System.Drawing.Size(Screen.PrimaryScreen.Bounds.Width, Screen.PrimaryScreen.Bounds.Height);
}
h.inject({}) { |m, (k,v)| m[k.sub(/^_/,'')] = v; m }
Your path includes " at the beginning and at the end. Drop the quotes, and it'll be ok.
The \" at the beginning and end of what you see in VS Debugger is what tells us that the quotes are literally in the string.
$dbh = new PDO('pgsql:host=localhost;port=5432;dbname=###;user=###;password=##');
For PDO type connection uncomment
extension=php_pdo_pgsql.dll
and comment with
;extension=php_pgsql.dll
$dbh = pg_connect("host=localhost dbname=### user=### password=####");
For pgconnect type connection comment
;extension=php_pdo_pgsql.dll
and uncomment
extension=php_pgsql.dll
Both the connections should work.
I have already upvoted the @dasblinkenlight answer since the Median of Medians algorithm in fact solves this problem in O(n) time. I only want to add that this problem could be solved in O(n) time by using heaps also. Building a heap could be done in O(n) time by using the bottom-up. Take a look to the following article for a detailed explanation Heap sort
Supposing that your array has N elements, you have to build two heaps: A MaxHeap that contains the first N/2 elements (or (N/2)+1 if N is odd) and a MinHeap that contains the remaining elements. If N is odd then your median is the maximum element of MaxHeap (O(1) by getting the max). If N is even, then your median is (MaxHeap.max()+MinHeap.min())/2 this takes O(1) also. Thus, the real cost of the whole operation is the heaps building operation which is O(n).
BTW this MaxHeap/MinHeap algorithm works also when you don't know the number of the array elements beforehand (if you have to resolve the same problem for a stream of integers for e.g). You can see more details about how to resolve this problem in the following article Median Of integer streams
Try this instead:
ping -c2 -s16 sntdn | awk '{print NR " | " strftime("%Y-%m-%d_%H:%M:%S") " | " $0 }'
Check if it suits you

If you have some process listening on port 8080 then you can always configure tomcat to listen on a different port. To change the listener port by editing your server.xml
located under tomcat server conf
directory.
Search for Connector port="8080"
in server.xml and change the port number to some other port.
I happened to encounter a similar kind of issue after setting up local internal JFrog Docker Private Registry on Amazon Linux.
THE followings I did to solve the issue:
Added "--insecure-registry xx.xx.xx.xx:8081" by modifying the OPTIONS variable in the /etc/sysconfig/docker file:
OPTIONS="--default-ulimit nofile=1024:40961 --insecure-registry hostname:8081"
Then restarted the docker.
I was then able to login to the local docker registry using:
docker login -u admin -p password hostname:8081
What are metaclasses? What do you use them for?
TLDR: A metaclass instantiates and defines behavior for a class just like a class instantiates and defines behavior for an instance.
Pseudocode:
>>> Class(...)
instance
The above should look familiar. Well, where does Class
come from? It's an instance of a metaclass (also pseudocode):
>>> Metaclass(...)
Class
In real code, we can pass the default metaclass, type
, everything we need to instantiate a class and we get a class:
>>> type('Foo', (object,), {}) # requires a name, bases, and a namespace
<class '__main__.Foo'>
A class is to an instance as a metaclass is to a class.
When we instantiate an object, we get an instance:
>>> object() # instantiation of class
<object object at 0x7f9069b4e0b0> # instance
Likewise, when we define a class explicitly with the default metaclass, type
, we instantiate it:
>>> type('Object', (object,), {}) # instantiation of metaclass
<class '__main__.Object'> # instance
Put another way, a class is an instance of a metaclass:
>>> isinstance(object, type)
True
Put a third way, a metaclass is a class's class.
>>> type(object) == type
True
>>> object.__class__
<class 'type'>
When you write a class definition and Python executes it, it uses a metaclass to instantiate the class object (which will, in turn, be used to instantiate instances of that class).
Just as we can use class definitions to change how custom object instances behave, we can use a metaclass class definition to change the way a class object behaves.
What can they be used for? From the docs:
The potential uses for metaclasses are boundless. Some ideas that have been explored include logging, interface checking, automatic delegation, automatic property creation, proxies, frameworks, and automatic resource locking/synchronization.
Nevertheless, it is usually encouraged for users to avoid using metaclasses unless absolutely necessary.
When you write a class definition, for example, like this,
class Foo(object):
'demo'
You instantiate a class object.
>>> Foo
<class '__main__.Foo'>
>>> isinstance(Foo, type), isinstance(Foo, object)
(True, True)
It is the same as functionally calling type
with the appropriate arguments and assigning the result to a variable of that name:
name = 'Foo'
bases = (object,)
namespace = {'__doc__': 'demo'}
Foo = type(name, bases, namespace)
Note, some things automatically get added to the __dict__
, i.e., the namespace:
>>> Foo.__dict__
dict_proxy({'__dict__': <attribute '__dict__' of 'Foo' objects>,
'__module__': '__main__', '__weakref__': <attribute '__weakref__'
of 'Foo' objects>, '__doc__': 'demo'})
The metaclass of the object we created, in both cases, is type
.
(A side-note on the contents of the class __dict__
: __module__
is there because classes must know where they are defined, and __dict__
and __weakref__
are there because we don't define __slots__
- if we define __slots__
we'll save a bit of space in the instances, as we can disallow __dict__
and __weakref__
by excluding them. For example:
>>> Baz = type('Bar', (object,), {'__doc__': 'demo', '__slots__': ()})
>>> Baz.__dict__
mappingproxy({'__doc__': 'demo', '__slots__': (), '__module__': '__main__'})
... but I digress.)
type
just like any other class definition:Here's the default __repr__
of classes:
>>> Foo
<class '__main__.Foo'>
One of the most valuable things we can do by default in writing a Python object is to provide it with a good __repr__
. When we call help(repr)
we learn that there's a good test for a __repr__
that also requires a test for equality - obj == eval(repr(obj))
. The following simple implementation of __repr__
and __eq__
for class instances of our type class provides us with a demonstration that may improve on the default __repr__
of classes:
class Type(type):
def __repr__(cls):
"""
>>> Baz
Type('Baz', (Foo, Bar,), {'__module__': '__main__', '__doc__': None})
>>> eval(repr(Baz))
Type('Baz', (Foo, Bar,), {'__module__': '__main__', '__doc__': None})
"""
metaname = type(cls).__name__
name = cls.__name__
parents = ', '.join(b.__name__ for b in cls.__bases__)
if parents:
parents += ','
namespace = ', '.join(': '.join(
(repr(k), repr(v) if not isinstance(v, type) else v.__name__))
for k, v in cls.__dict__.items())
return '{0}(\'{1}\', ({2}), {{{3}}})'.format(metaname, name, parents, namespace)
def __eq__(cls, other):
"""
>>> Baz == eval(repr(Baz))
True
"""
return (cls.__name__, cls.__bases__, cls.__dict__) == (
other.__name__, other.__bases__, other.__dict__)
So now when we create an object with this metaclass, the __repr__
echoed on the command line provides a much less ugly sight than the default:
>>> class Bar(object): pass
>>> Baz = Type('Baz', (Foo, Bar,), {'__module__': '__main__', '__doc__': None})
>>> Baz
Type('Baz', (Foo, Bar,), {'__module__': '__main__', '__doc__': None})
With a nice __repr__
defined for the class instance, we have a stronger ability to debug our code. However, much further checking with eval(repr(Class))
is unlikely (as functions would be rather impossible to eval from their default __repr__
's).
__prepare__
a namespaceIf, for example, we want to know in what order a class's methods are created in, we could provide an ordered dict as the namespace of the class. We would do this with __prepare__
which returns the namespace dict for the class if it is implemented in Python 3:
from collections import OrderedDict
class OrderedType(Type):
@classmethod
def __prepare__(metacls, name, bases, **kwargs):
return OrderedDict()
def __new__(cls, name, bases, namespace, **kwargs):
result = Type.__new__(cls, name, bases, dict(namespace))
result.members = tuple(namespace)
return result
And usage:
class OrderedMethodsObject(object, metaclass=OrderedType):
def method1(self): pass
def method2(self): pass
def method3(self): pass
def method4(self): pass
And now we have a record of the order in which these methods (and other class attributes) were created:
>>> OrderedMethodsObject.members
('__module__', '__qualname__', 'method1', 'method2', 'method3', 'method4')
Note, this example was adapted from the documentation - the new enum in the standard library does this.
So what we did was instantiate a metaclass by creating a class. We can also treat the metaclass as we would any other class. It has a method resolution order:
>>> inspect.getmro(OrderedType)
(<class '__main__.OrderedType'>, <class '__main__.Type'>, <class 'type'>, <class 'object'>)
And it has approximately the correct repr
(which we can no longer eval unless we can find a way to represent our functions.):
>>> OrderedMethodsObject
OrderedType('OrderedMethodsObject', (object,), {'method1': <function OrderedMethodsObject.method1 at 0x0000000002DB01E0>, 'members': ('__module__', '__qualname__', 'method1', 'method2', 'method3', 'method4'), 'method3': <function OrderedMet
hodsObject.method3 at 0x0000000002DB02F0>, 'method2': <function OrderedMethodsObject.method2 at 0x0000000002DB0268>, '__module__': '__main__', '__weakref__': <attribute '__weakref__' of 'OrderedMethodsObject' objects>, '__doc__': None, '__d
ict__': <attribute '__dict__' of 'OrderedMethodsObject' objects>, 'method4': <function OrderedMethodsObject.method4 at 0x0000000002DB0378>})
I struggled a lot with something similar. Try the following:
If this doesn't help, take a look at this article. It's on PHP, but it describes exactly which headers must be set to which values for CORS to work.
Expanding on Tony's answer, and also answering Dhaval Ptl's question, to get the true accordion effect and only allow one row to be expanded at a time, an event handler for show.bs.collapse can be added like so:
$('.collapse').on('show.bs.collapse', function () {
$('.collapse.in').collapse('hide');
});
I modified his example to do this here: http://jsfiddle.net/QLfMU/116/
You can declare an object of a class in another Class,that's possible but you cant initialize that object. For that you need to do something like this :--> (inside main)
Orderbook o1;
o1.m.check(side)
but that would be unnecessary. Keeping things short :-
You can't call functions inside a Class
Yes! You can use Range.EntireColumn
MSDN
dim column : column = 4
dim column_range : set column_range = Sheets(1).Cells(column).EntireColumn
If you were after a specific column, you could create a hard coded column range with the syntax e.g. Range("D:D")
.
However, I'd use entire column as it provides more flexibility to change that column at a later time.
Worksheet.Columns
provides Range access to a column within a worksheet. MSDN
If you would like access to the first column of the first sheet. You would
call the Columns
function on the worksheet.
dim column_range: set column_range = Sheets(1).Columns(1)
The Columns
property is also available on any Range
MSDN
EntireRow
can also be useful if you have a range for a single cell but would like to reach other cells on the row, akin to a LOOKUP
dim id : id = 12345
dim found : set found = Range("A:A").Find(id)
if not found is Nothing then
'Get the fourth cell from the match
MsgBox found.EntireRow.Cells(4)
end if
While @AniketThakur's answer is very good. No one has answered the following question yet.
Can I only send pull requests via GitHub if I've forked a project?
No. If you are a contributor to a repository, you can: Make a local clone. Make a local branch. Add commits to that branch. Push the local branch back to github (creating a remote branch in the process). Make a pull request requesting for that branch to be merged into the master branch (or whatever branch you like).
I'm using the TortoiseSVN client on Windows, and for me, setting store-passwords parameter as yes in %USERPROFILE%\AppData\Roaming\Subversion\config
does not help to store the password.
The password was successfully saved after removing this folder (just in case renaming):
%USERPROFILE%\AppData\Roaming\Subversion\auth

Thanks so much Jason Pan for suggesting that method. The thread1 if statement is not atomic, so that while that statement executes, it's possible for thread2 to intrude on thread1, allowing non-reachable code to be reached. I've organized ideas from the prior posts into a complete demonstration program (below) that I ran with Python 2.7.
With some thoughtful analysis I'm sure we could gain further insight, but for now I think it's important to demonstrate what happens when non-atomic behavior meets threading.
# ThreadTest01.py - Demonstrates that if non-atomic actions on
# global variables are protected, task can intrude on each other.
from threading import Thread
import time
# global variable
a = 0; NN = 100
def thread1(threadname):
while True:
if a % 2 and not a % 2:
print("unreachable.")
# end of thread1
def thread2(threadname):
global a

As predicted, in running the example, the "unreachable" code sometimes is actually reached, producing output.
Just to add, when I inserted a lock acquire/release pair into thread1 I found that the probability of having the "unreachable" message print was greatly reduced. To see the message I reduced the sleep time to 0.01 sec and increased NN to 1000.
With a lock acquire/release pair in thread1 I didn't expect to see the message at all, but it's there. After I inserted a lock acquire/release pair also into thread2, the message no longer appeared. In hind signt, the increment statement in thread2 probably also is non-atomic.
The practical reason for this is often that the python or django shells have opened a request to the DB and it wasn't closed properly; killing your terminal access often frees it up. I had this error on running command line tests today.
Edit: I get periodic upvotes on this. If you'd like to kill access without rebooting the terminal, then from commandline you can do:
from django import db
db.connections.close_all()
add this line in your build.gradle

This is one of the most accurate answers that is able to resolve the birthday of 29th of Feb compared to any year of 28th Feb.
public int GetAge(DateTime birthDate)
{
int age = DateTime.Now.Year - birthDate.Year;
if (birthDate.DayOfYear > DateTime.Now.DayOfYear)
age--;
return age;
}
Josh David Miller is correct.
PCoelho, In case you're wondering what $compile
does behind the scenes and how HTML output is generated from the directive, please take a look below
The $compile
service compiles the fragment of HTML("< test text='n' >< / test >"
) that includes the directive("test" as an element) and produces a function. This function can then be executed with a scope to get the "HTML output from a directive".
var compileFunction = $compile("< test text='n' > < / test >");
var HtmlOutputFromDirective = compileFunction($scope);

Inspired from it, an approach can be made by creating a temporary table and inserting the constraints in that table, and then dropping the constraints and then reapplying them from that temporary table. Enough said here is what i am talking about
SET NOCOUNT ON
DECLARE @temptable TABLE(
Id INT PRIMARY KEY IDENTITY(1, 1),
FKConstraintName VARCHAR(255),
FKConstraintTableSchema VARCHAR(255),
FKConstraintTableName VARCHAR(255),
FKConstraintColumnName VARCHAR(255),
PKConstraintName VARCHAR(255),
PKConstraintTableSchema VARCHAR(255),
PKConstraintTableName VARCHAR(255),
PKConstraintColumnName VARCHAR(255)
)
INSERT INTO @temptable(FKConstraintName, FKConstraintTableSchema, FKConstraintTableName, FKConstraintColumnName)
SELECT
KeyColumnUsage.CONSTRAINT_NAME,
KeyColumnUsage.TABLE_SCHEMA,
KeyColumnUsage.TABLE_NAME,
KeyColumnUsage.COLUMN_NAME
FROM
INFORMATION_SCHEMA.KEY_COLUMN_USAGE KeyColumnUsage
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS TableConstraints
ON KeyColumnUsage.CONSTRAINT_NAME = TableConstraints.CONSTRAINT_NAME
WHERE
TableConstraints.CONSTRAINT_TYPE = 'FOREIGN KEY'
UPDATE @temptable SET
PKConstraintName = UNIQUE_CONSTRAINT_NAME
FROM
@temptable tt
INNER JOIN INFORMATION_SCHEMA.REFERENTIAL_CONSTRAINTS ReferentialConstraint
ON tt.FKConstraintName = ReferentialConstraint.CONSTRAINT_NAME
UPDATE @temptable SET
PKConstraintTableSchema = TABLE_SCHEMA,
PKConstraintTableName = TABLE_NAME
FROM @temptable tt
INNER JOIN INFORMATION_SCHEMA.TABLE_CONSTRAINTS TableConstraints
ON tt.PKConstraintName = TableConstraints.CONSTRAINT_NAME
UPDATE @temptable SET
PKConstraintColumnName = COLUMN_NAME
FROM @temptable tt
INNER JOIN INFORMATION_SCHEMA.KEY_COLUMN_USAGE KeyColumnUsage
ON tt.PKConstraintName = KeyColumnUsage.CONSTRAINT_NAME
--Now to drop constraint:
SELECT
'
ALTER TABLE [' + FKConstraintTableSchema + '].[' + FKConstraintTableName + ']
DROP CONSTRAINT ' + FKConstraintName + '
GO'
FROM
@temptable
--Finally to add constraint:
SELECT
'
ALTER TABLE [' + FKConstraintTableSchema + '].[' + FKConstraintTableName + ']
ADD CONSTRAINT ' + FKConstraintName + ' FOREIGN KEY(' + FKConstraintColumnName + ') REFERENCES [' + PKConstraintTableSchema + '].[' + PKConstraintTableName + '](' + PKConstraintColumnName + ')
GO'
FROM

It is not mere a syntactic sugar. Try this:
x = [] # empty list
x += "something" # iterates over the string and appends to list
print(x) # ['s', 'o', 'm', 'e', 't', 'h', 'i', 'n', 'g']
versus
x = [] # empty list
x = x + "something" # TypeError: can only concatenate list (not "str") to list
The +=
operator invokes the __iadd__()
list method, while +
one invokes the __add__()
one. They do different things with lists.
You mean you don't know the sizes of the arrays at compile-time? At run-time they could be found by the value of lastone.length
and lastwo.length
.
You could make the webpage scroll down to a position where you can't see the address bar, and if the user scrolls, the page should return to your set position. In that way, Mobile browsers when scrolled down , will try to guve you full-screen experience. So it will hide the address bar. I don't know the code, someone else might put up the code.
It sounds like you're essentially trying to use the hash code as a key in a map (which is what HashSets do behind the scenes). You could just do it explicitly, by declaring HashMap<Integer, MyHashObject>
.
There is no get
for HashSets because typically the object you would supply to the get
method as a parameter is the same object you would get back.
Well, null
is not an instance of any type. Rather, it is an invalid reference.
However, System.DbNull.Value
, is a valid reference to an instance of System.DbNull
(System.DbNull
is a singleton and System.DbNull.Value
gives you a reference to the single instance of that class) that represents nonexistent* values in the database.
*We would normally say null
, but I don't want to confound the issue.
So, there's a big conceptual difference between the two. The keyword null
represents an invalid reference. The class System.DbNull
represents a nonexistent value in a database field. In general, we should try avoid using the same thing (in this case null
) to represent two very different concepts (in this case an invalid reference versus a nonexistent value in a database field).
Keep in mind, this is why a lot of people advocate using the null object pattern in general, which is exactly what System.DbNull
is an example of.
This check is compatible with both Python 2.x and Python 3.x.
import six
isinstance(obj, six.class_types)
This is basically a wrapper function that performs the same check as in andrea_crotti answer.
Example:
>>> import datetime
>>> isinstance(datetime.date, six.class_types)
>>> True
>>> isinstance(datetime.date.min, six.class_types)
>>> False
loadXMLDoc JS function should return false, otherwise it will result in postback.
The only way I found is check if navigator.userAgent contains iPhone or iPad word
if (navigator.userAgent.toLowerCase().match(/(ipad|iphone)/)) {

There's a lot of similar responses to this question, but none of them fully touch on the root cause. Sebastian Schmid's comment on the original post touches on it but not fully. Here's my take as of 2018-11-06:
Root Cause
When you try to upload a plugin through the WordPress admin interface, WordPress will make a call over to a function called "get_filesystem_method()" (ref: /wp-admin/includes/file.php:1549). This routine will attempt to write a file to the location in question (in this case the plugin directory). It can of course fail here immediately if file permissions aren't setup right to allow the WordPress user (think the user identity executing the php) to write the file to the location in question.
If the file can be created, this function then detects the file owner of the temporary file, along with the file owner of the function's current file (ref: /wp-admin/includes/file.php:1572) and compares the two. If they match then, in WordPress's words, "WordPress is creating files as the same owner as the WordPress files, this means it's safe to modify & create new files via PHP" and your plugin is uploaded successfully without the FTP Credentials prompt. If they don't match, you get the FTP Credentials prompt.
Fixes
Ensure the identity that is running your php process is the file owner for either:
a) All WordPress application files, or...
b) At the very least the /wp-admin/includes/file.php file
Final Comments
I'm not overly keen on specifically applying file ownership to the file.php to work around this issue (it feels a tad hacky to say the least!). It seems to me at this point that the WordPress code base is leaning towards having us execute the PHP process under the same user principal as the file owner for the WordPress application files. I would welcome some comments from the community on this.
Here is a link from developer.nokia.com wiki pages, which explains how to install Windows Phone 8 SDK on a Virtual Machine with Working Emulator
And another link here
AFAIK, it is not possible to directly install WP8 SDK in Windows 7, because WP8 sdk is VS 2012 supported and also its emulator works on a Hyper-V (which is integrated into the Windows 8).
If you want to get a long-as-possible (not sure what limits there are), similar to Solaris' pargs, you can use this on Linux & OSX:

Real problem is when you need draw some tile/sprites intersecting/spanning two or more other tiles.
After 2 (hard) months of personal analisys of problem I finally found and implemented a "correct render drawing" for my new cocos2d-js game. Solution consists in mapping, for each tile (susceptible), which sprites are "front, back, top and behind". Once doing that you can draw them following a "recursive logic".
You can change the memory_limit
value in your php.ini
Try increasing the limit in your php.ini file
Use -1 for unlimited or define an explicit value like 2G
memory_limit = -1
Note: Composer internally increases the memory_limit to 1.5G.
Read the documentation getcomposer.org
Refresh the page containing the script whilst the developer tools are open on the scripts tab. This will add a (program) entry in the file list which shows the html of the page including the script. From here you can add breakpoints.
Since your Print() method presumably deals with Text data, could you rewrite it to accept a TextWriter
parameter?
The library provides a StringWriter: TextWriter
but not a StringStream. I suppose you could create one by wrapping a MemoryStream, but is it really necessary?
After the Update:
void Main()
{
string myString; // outside using
using (MemoryStream stream = new MemoryStream ())
{
Print(stream);
myString = Encoding.UTF8.GetString(stream.ToArray());
}
...
}
You may want to change UTF8 to ASCII, depending on the encoding used by Print().

server_name www.test.com test.com;

}
boolean
can only be true
or false
because it's a primitive datatype (+ a boolean
variables default value is false
). You can use the class Boolean
instead if you want to use null
values. Boolean is a reference type, that's the reason you can assign null
to a Boolean "variable". Example:
Boolean testvar = null;
if (testvar == null) { ...}
Well, here's an example for overloaded constructors.
public class Employee
{
private String name;
private int age;
public Employee()
{
System.out.println("We are inside Employee() constructor");
}
public Employee(String name)
{
System.out.println("We are inside Employee(String name) constructor");
this.name = name;
}
public Employee(String name, int age)
{
System.out.println("We are inside Employee(String name, int age) constructor");
this.name = name;
this.age = age;
}
public Employee(int age)
{
System.out.println("We are inside Employee(int age) constructor");
this.age = age;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public int getAge()
{
return age;
}
public void setAge(int age)
{
this.age = age;
}
}
In the above example you can see overloaded constructors. Name of the constructors is same but each constructors has different parameters.
Here are some resources which throw more light on constructor overloading in java,
There is a very simple and easy solution to your question:
var districtId = 210;
if (DistrictsEnum[districtId] != null) {
// Returns 'undefined' if the districtId not exists in the DistrictsEnum
model.handlingDistrictId = districtId;
}
We had the same issue, working from JS code (i.e. not from HTML anchor). This is how we solved that:
If needed, virtually alter current URL through $location
service. This might be useful if your destination is just a variation on the current URL, so that you can take advantage of $location
helper methods. E.g. we ran $location.search(..., ...)
to just change value of a querystring paramater.
Build up the new destination URL, using current $location.url()
if needed. In order to work, this new one had to include everything after schema, domain and port. So e.g. if you want to move to:
http://yourdomain.com/YourAppFolder/YourAngularApp/#/YourArea/YourAction?culture=en
then you should set URL as in:
var destinationUrl = '/YourAppFolder/YourAngularApp/#/YourArea/YourAction?culture=en';
(with the leading '/'
as well).
Assign new destination URL at low-level: $window.location.href = destinationUrl;
Force reload, still at low-level: $window.location.reload();
To stage only the deleted files:
for x in $(git status | grep deleted | awk '{print $2}'); do git rm $x; done
Or (the xargs way):
git status | awk '/deleted/ {print $2}' | xargs git rm
You can alias your preferred command set for convenient later use.
From .Net 3.5 you can use LINQ extension method that (sometimes) makes code flow a bit better.
Usage looks like this:
using System.Linq;
// ...
public void My()
{
var myArray = new[] { "abc", "123", "zyx" };
List<string> myList = myArray.ToList();
}
PS. There's also ToArray()
method that works in other way.
Inspired by all the responses related on the internet, finally I've found the solution to correctly configure the Proxy for R and Rstudio.
There are several steps to follow, perhaps some of the steps are useless, but the combination works!
Add environment variables http_proxy
and https_proxy
with proxy details.
variable name: http_proxy
variable value: https://user_id:password@your_proxy:your_port/
variable name: https_proxy
variable value: https:// user_id:password@your_proxy:your_port
If you start R from a desktop icon, you can add the --internet
flag to the target line (right click -> Properties)
e.g."C:\Program Files\R\R-2.8.1\bin\Rgui.exe" --internet2
For RStudio just you have to do this:
Firstly, open RStudio like always, select from the top menu:
Tools-Global Options-Packages
Uncheck the option: Use Internet Explorer library/proxy for HTTP
Find the file (.Renviron
) in your computer, most probably you would find it here: C:\Users\your user name\Documents
.
Note that: if it does not exist you can create it just by writing this command in R:
file.edit('~/.Renviron')
Then add these six lines to the initials of the file:
options(internet.info = 0)
http_proxy = https:// user_id:password@your_proxy:your_port
http_proxy_user = user_id:password
https_proxy = https:// user_id:password0@your_proxy:your_port
https_proxy_user = user_id:password
ftp_proxy = user_id:password@your_proxy:your_port
Restart R. Type the following commands in R to assure that the configuration above works well:
Sys.getenv("http_proxy")
Sys.getenv("http_proxy_user")
Sys.getenv("https_proxy")
Sys.getenv("https_proxy_user")
Sys.getenv("ftp_proxy")
Now you can install the packages as you want by using the command like:
install.packages("mlr",method="libcurl")
It's important to add method="libcurl"
, otherwise it won't work.
Im using Asp.Net Core 2.2 with MVC and Razor cshtml My JQuery is referenced in a layout page I needed to add the following to my view.cshtml:
@section Scripts {
$script-here
}
Frustratingly, you have to enable showing the dividers from code in your activity. For example:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set the view to your layout
setContentView(R.layout.yourlayout);
// Find the LinearLayout within and enable the divider
((LinearLayout)v.findViewById(R.id.llTopBar)).
setShowDividers(LinearLayout.SHOW_DIVIDER_MIDDLE);
}
The best way is to use the ng-options
directive on the select
element.
Controller
function Ctrl($scope) {
// sort options
$scope.products = [{
value: 'prod_1',
label: 'Product 1'
}, {
value: 'prod_2',
label: 'Product 2'
}];
}
HTML
<select ng-model="selected_product"
ng-options="product as product.label for product in products">
</select>
This will bind the selected product
object to the ng-model
property - selected_product
. After that you can use this:
<p>Ordered by: {{selected_product.label}}</p>

Use a packet analyzer to intercept the packets to/from somewhere.com

Time-outs or connections refused could mean that the remote host is too busy.
Here is the way I executed the program without environment variable configured.
Java file execution procedure: After you saved a file MyFirstJavaProgram.java
Enter the whole Path of "Javac" followed by java file For executing output Path of followed by comment <-cp> followed by followed by
C:\Program Files\Java\jdk1.8.0_101\bin>javac C:\Sample\MyFirstJavaProgram2.java C:\Program Files\Java\jdk1.8.0_101\bin>java -cp C:\Sample MyFirstJavaProgram2 Hello World
SYSDATE returns the system date, of the system on which the database resides
CURRENT_TIMESTAMP returns the current date and time in the session time zone, in a value of datatype TIMESTAMP WITH TIME ZONE
execute this comman
ALTER SESSION SET TIME_ZONE = '+3:0';
and it will provide you the same result.
If you're looking to do something with a list of files, you can use find combined with the bash $()
construct (better than backticks since it's allowed to nest).
for example, say you're at the top level of your project directory and you want a list of all C files starting with "btree". The command:
find . -type f -name 'btree*.c'
will return a list of them. But this doesn't really help with doing something with them.
So, let's further assume you want to search all those file for the string "ERROR" or edit them all. You can execute one of:
grep ERROR $(find . -type f -name 'btree*.c')
vi $(find . -type f -name 'btree*.c')
to do this.
