Xdebug and the DBGp plugin for Notepad++ for heavy duty bug hunting, FirePHP for lightweight stuff. Quick and dirty? Nothing beats dBug.
<?php
ini_set('xdebug.max_nesting_level', 9999);
... your code ...
P.S. Change 9999 to any number you want.
Do you have Zend, IonCube, or xDebug installed? If so, that is probably where you are getting this error from.
I ran into this a few years ago, and it ended up being Zend putting that limit there, not PHP. Of course removing it will let you go past the 100 iterations, but you will eventually hit the memory limits.
I'd like to recommend var_export($array)
- it doesn't show types, but it generates syntax you can use in your code :)
An easy solution working on Linux distributions similar to Ubuntu
sudo php5dismod xdebug
sudo service apache2 restart
you can run this small php
code
<?php
phpinfo();
?>
Copy the whole output page, paste it in this link. Then analyze. It will show if Xdebug is installed or not. And it will give instructions to complete the installation.
Jeff Bridgman is correct. All you need is
background: url('pic.jpg')
and this assumes that pic is in the same folder as your html.
Also, Roberto's answer works fine. Tested in Firefox, and IE. Thanks to Raptor for adding formatting that displays full picture fit to screen, and without scrollbars... In a folder f, on the desktop is this html and a picture, pic.jpg, using your userid. Make those substitutions in the below:
<html>
<head>
<style>
body {
background: url('file:///C:/Users/userid/desktop/f/pic.jpg') no-repeat center center fixed;
background-size: cover; /* for IE9+, Safari 4.1+, Chrome 3.0+, Firefox 3.6+ */
-webkit-background-size: cover; /* for Safari 3.0 - 4.0 , Chrome 1.0 - 3.0 */
-moz-background-size: cover; /* optional for Firefox 3.6 */
-o-background-size: cover; /* for Opera 9.5 */
margin: 0; /* to remove the default white margin of body */
padding: 0; /* to remove the default white margin of body */
overflow: hidden;
}
</style>
</head>
<body>
hello
</body>
</html>
You could try some of the generic code in the Apache Commons project. The Collections subproject provides code for finding objects that match a particular Predicate, as well as a large number of predicates (equals, null, instanceof, etc). The BeanUtils subproject allows you to make predicates that test properties of beans.
Use the CollectionUtils class to search within a collection. There are a few methods for this, but check out the select() method, in particular. Use the following classes to construct predicates, or write your own: Predicate, PredicateUtils, BeanPredicate.
This is all sometimes a bit cumbersome, but at least it's generic! :-)
Try a using namespace std;
at the top of game.h
or use the fully-qualified std::string
instead of string
.
The namespace
in game.cpp
is after the header is included.
I had to install IIS Media Services 4.1 from the Windows Web App Gallery.
I would accept ldav1s' answer if I were you, but I just want to point out that 'else if' can be written in terms of 'else's and 'if's in any language:

else
if HAVE_SERVER
libtest_LIBS = $(top_builddir)/libserver.la
else
libtest_LIBS =

Some time ago i created an excel file with supported dimensions
Hope this will be helpful for somebody
To be honest i lost the idea, but it refers another screen feature as size (not only density)

One of Androids powerful feature is the AsyncTask class.
To work with it, you have to first extend it and override doInBackground
(...).
doInBackground
automatically executes on a worker thread, and you can add some
listeners on the UI Thread to get notified about status update, those functions are
called: onPreExecute()
, onPostExecute()
and onProgressUpdate()
You can find a example here.
Refer to below post for other alternatives:
The result produced by the Query is having no of rows that need proper handling this issue can be resolved if you provide the valid handler in the query like 1. limiting the query to return one single row 2. this can also be done by providing "select max(column)" that will return the single row

2012-03-01 00:00:00.000 1100.00 NULL NULL
I think to add timestamp to every record and get the latest. In this situation you can get any ids, pack rows and other ops.
I had this issue because a method I was trying to implement required a std::unique_ptr<Queue>(myQueue)
as a parameter, but the Queue
class is abstract. I solved that by using a QueuePtr(myQueue)
constructor like so:
using QueuePtr = std::unique_ptr<Queue>;
and used that in the parameter list instead. This fixes it because the initializer tries to create a copy of Queue
when you make a std::unique_ptr
of its type, which can't happen.
In my case I was calling s3request.promise().then()
incorreclty which caused two executions of the request happening when only one call was done.
What I mean is that I was iterating through 6 objects but 12 requests were made (you can check by logging in the console or debuging network in the browser)
Since the timestamp for the second, unwanted, request did not match the signture of the firs one this produced this issue.
Sure you just need to setup a local web server. Check out XAMPP: http://www.apachefriends.org/en/xampp.html
That will get you up and running in about 10 minutes.
There is now a way to run php locally without installing a server: https://stackoverflow.com/a/21872484/672229
Yes but the files need to be processed. For example you can install test servers like mamp / lamp / wamp depending on your plateform.
Basically you need apache / php running.
The key bindings has been changed with version 1.20:
SHIFT+ALT+0 for Linux.
Presumably the same works for Windows also and CMD+OPT+0 for Mac.
This is incorrect initialization. You interchanged row with col!
C = [[0 for row in range(len(A))] for col in range(len(B[0]))]
Correct initialization would be
C = [[0 for col in range(len(B[0]))] for row in range(len(A))]
Also I would suggest using better naming conventions. Will help you a lot in debugging. For example:
def matrixmult (A, B):
rows_A = len(A)
cols_A = len(A[0])
rows_B = len(B)
cols_B = len(B[0])
if cols_A != rows_B:
print "Cannot multiply the two matrices. Incorrect dimensions."
return
# Create the result matrix
# Dimensions would be rows_A x cols_B
C = [[0 for row in range(cols_B)] for col in range(rows_A)]
print C
for i in range(rows_A):
for j in range(cols_B):
for k in range(cols_A):
C[i][j] += A[i][k] * B[k][j]
return C
You can do a lot more, but you get the idea...
Your code is in the default package, i.e. you have source all files in src/main/java with no custom package. I strongly suggest u to create package n then place your source file in it.
Ex-
src->
main->
java->
com.myfirst.example
Example.java
com.myfirst.example.controller
PersonController.java
com.myfirst.example.repository
PersonRepository.java
com.myfirst.example.model
Person.java
I hope it will resolve your problem.
You can use the top level containers root pane to set a default button, which will allow it to respond to the enter.
SwingUtilities.getRootPane(submitButton).setDefaultButton(submitButton);
This, of course, assumes you've added the button to a valid container ;)
UPDATED
This is a basic example using the JRootPane#setDefaultButton
and key bindings API
public class DefaultButton {
public static void main(String[] args) {
new DefaultButton();
}
public DefaultButton() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
}
JFrame frame = new JFrame("Test");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLayout(new BorderLayout());
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
private JButton button;
private JLabel label;
private int count;
public TestPane() {
label = new JLabel("Press the button");
button = new JButton("Press me");
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridy = 0;
add(label, gbc);
gbc.gridy++;
add(button, gbc);
gbc.gridy++;
add(new JButton("No Action Here"), gbc);
button.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
doButtonPressed(e);
}
});
InputMap im = button.getInputMap(WHEN_ANCESTOR_OF_FOCUSED_COMPONENT);
ActionMap am = button.getActionMap();
im.put(KeyStroke.getKeyStroke(KeyEvent.VK_SPACE, 0), "spaced");
am.put("spaced", new AbstractAction() {
@Override
public void actionPerformed(ActionEvent e) {
doButtonPressed(e);
}
});
}
@Override
public void addNotify() {
super.addNotify();
SwingUtilities.getRootPane(button).setDefaultButton(button);
}
protected void doButtonPressed(ActionEvent evt) {
count++;
label.setText("Pressed " + count + " times");
}
}
}
This of course, assumes that the component with focus does not consume the key event in question (like the second button consuming the space or enter keys
Sorry I've not tested this but I think it's done like this:
var filemap = new System.Configuration.ExeConfigurationFileMap();
System.Configuration.Configuration config = System.Configuration.ConfigurationManager.OpenMappedExeConfiguration(filemap, System.Configuration.ConfigurationUserLevel.None);
//usage: config.AppSettings["xxx"]
First, one should check if the last character is a comma. If it exists, remove it.
if (str.indexOf(',', this.length - ','.length) !== -1) {
str = str.substring(0, str.length - 1);
}
NOTE str.indexOf(',', this.length - ','.length) can be simplified to str.indexOf(',', this.length - 1)
As of C#6 the best way to get the name of an enum is the new nameof
operator:
nameof(MyEnum.EnumValue);
// Ouputs
> "EnumValue"
This works at compile time, with the enum being replaced by the string in the compiled result, which in turn means this is the fastest way possible.
Any use of enum names does interfere with code obfuscation, if you consider obfuscation of enum names to be worthwhile or important - that's probably a whole other question.
You have some special words from CMAKE, take a look:

I'm actually surprised no one provided my answer. This is what you do (this will work if you have at least 1 eligible device):

You are trying to call a javascript function. If you want to call a PHP function, you have to use for example a form:
<form action="action_page.php">
First name:<br>
<input type="text" name="firstname" value="Mickey">
<br>
Last name:<br>
<input type="text" name="lastname" value="Mouse">
<br><br>
<input type="submit" value="Submit">
</form>
(Original Code from: http://www.w3schools.com/html/html_forms.asp)
So if you want do do a asynchron call, you could use 'Ajax' - and yeah, that's the Javascript-Way. But I think, that my code example is enough for this time :)
Today I accidentally solved the issue:
Press finish.
[Optional scenario]: If project(s) and their containing folders have been renamed with the fully qualified package names then simply click on project node parent (where you see project package name instead of project's old name) in Eclipse and rename project with old name. Eclipse will rename folder too.
P.S. Tested on Eclipse Juno.
Edit: Many times have passed since this answer and new Eclipse and Android SDK arrived. They have no much more problems during importing existing projects. The only thing one has to consider before importing is to move project folders(those ones one is willing to import) outside of eclipse workspace dir and then check checkboxes ("copy projects into working sets", "add projects into wokring sets") in import wizard dialog. Also I recommend doing this with latest Android SDK because it no more imports projects with dummy names and does not rename folders as it did in some custom cases.
If referrer

For those using NHibernate, this is a port of [ram]'s code

Check your elasticsearch.yml, "transport.host" property must be "0.0.0.0" not "127.0.0.1" or "localhost"
The file permission is okay (0777) but i think your on the shared server, so to delete your file correctly use; 1. create a correct path to your file
// delete from folder
$filename = 'test.txt';
$ifile = '/newy/made/link/uploads/'. $filename; // this is the actual path to the file you want to delete.
unlink($_SERVER['DOCUMENT_ROOT'] .$ifile); // use server document root
// your file will be removed from the folder
That small code will do the magic and remove any selected file you want from any folder provided the actual file path is collect.
CFAbsoluteTimeGetCurrent()
returns the absolute time as a double
value, but I don't know what its precision is -- it might only update every dozen milliseconds, or it might update every microsecond, I don't know.
I can reproduce your problem if there are no files in the directory that were modified in the last hour. In that case, find . -mmin -60
returns nothing. The command find . -mmin -60 |xargs ls -l
, however, returns every file in the directory which is consistent with what happens when ls -l
is run without an argument.
To make sure that ls -l
is only run when a file is found, try:
find . -mmin -60 -type f -exec ls -l {} +
This is simple operation no need to use any external library.
You can use this class instead :) (handles even lists , nested lists and json)
public class Utility {
public static Map<String, Object> jsonToMap(Object json) throws JSONException {
if(json instanceof JSONObject)
return _jsonToMap_((JSONObject)json) ;
else if (json instanceof String)
{
JSONObject jsonObject = new JSONObject((String)json) ;
return _jsonToMap_(jsonObject) ;
}
return null ;
}
private static Map<String, Object> _jsonToMap_(JSONObject json) throws JSONException {
Map<String, Object> retMap = new HashMap<String, Object>();
if(json != JSONObject.NULL) {
retMap = toMap(json);
}
return retMap;
}
private static Map<String, Object> toMap(JSONObject object) throws JSONException {
Map<String, Object> map = new HashMap<String, Object>();
Iterator<String> keysItr = object.keys();
while(keysItr.hasNext()) {
String key = keysItr.next();
Object value = object.get(key);
if(value instanceof JSONArray) {
value = toList((JSONArray) value);
}
else if(value instanceof JSONObject) {
value = toMap((JSONObject) value);
}
map.put(key, value);
}
return map;
}
public static List<Object> toList(JSONArray array) throws JSONException {
List<Object> list = new ArrayList<Object>();
for(int i = 0; i < array.length(); i++) {
Object value = array.get(i);
if(value instanceof JSONArray) {
value = toList((JSONArray) value);
}
else if(value instanceof JSONObject) {
value = toMap((JSONObject) value);
}
list.add(value);
}
return list;
}
}
To convert your JSON string to hashmap use this :
HashMap<String, Object> hashMap = new HashMap<>(Utility.jsonToMap(response)) ;
SELECT (column name) FROM (table name) WHERE (column name) < DATEADD(Day,-30,GETDATE());
Example.
SELECT `name`, `phone`, `product` FROM `tbmMember` WHERE `dateofServicw` < (Day,-30,GETDATE());
Well, if you had already created the log4j.properties you would add its path to the classpath so it would be found during execution.
Yes, the thingy will search for this file in the classpath.
Since you said you looked into axis and didnt find one, I am assuming you dont have a log4j.properties, so here's a crude but complete example.
Create it somewhere and add to your classpath. Put it for example, in c:/proj/resources/log4j.properties
In your classpath you simple add .......;c:/proj/resources
# Root logger option
log4j.rootLogger=DEBUG, stdout, file
# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=c:/project/resources/t-output/log4j-application.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
I think this should work
destroyView : function () {
this.$el.remove();
}
All required parameters must be placed before any default arguments. Simply because they are mandatory, whereas default arguments are not. Syntactically, it would be impossible for the interpreter to decide which values match which arguments if mixed modes were allowed. A SyntaxError
is raised if the arguments are not given in the correct order:
Let us take a look at keyword arguments, using your function.
def fun1(a="who is you", b="True", x, y):
... print a,b,x,y
Suppose its allowed to declare function as above, Then with the above declarations, we can make the following (regular) positional or keyword argument calls:
func1("ok a", "ok b", 1) # Is 1 assigned to x or ?
func1(1) # Is 1 assigned to a or ?
func1(1, 2) # ?
How you will suggest the assignment of variables in the function call, how default arguments are going to be used along with keyword arguments.
>>> def fun1(x, y, a="who is you", b="True"):
... print a,b,x,y
...
Reference O'Reilly - Core-Python
Where as this function make use of the default arguments syntactically correct for above function calls.
Keyword arguments calling prove useful for being able to provide for out-of-order positional arguments, but, coupled with default arguments, they can also be used to "skip over" missing arguments as well.
The question has been asked on serverfault too.
You may want to take a look at this article which explains a lot about MySQL row sizes. It's important to note that even if you use TEXT or BLOB fields, your row size could still be over 8K (limit for InnoDB) because it stores the first 768 bytes for each field inline in the page.
The simplest way to fix this is to use the Barracuda file format with InnoDB. This basically gets rid of the problem altogether by only storing the 20 byte pointer to the text data instead of storing the first 768 bytes.
The method that worked for the OP there was:
Add the following to the my.cnf
file under [mysqld]
section.
innodb_file_per_table=1
innodb_file_format = Barracuda
ALTER
the table to use ROW_FORMAT=COMPRESSED
.
ALTER TABLE nombre_tabla
ENGINE=InnoDB
ROW_FORMAT=COMPRESSED
KEY_BLOCK_SIZE=8;
There is a possibility that the above still does not resolve your issues. It is a known (and verified) bug with the InnoDB engine, and a temporary fix for now is to fallback to MyISAM engine as temporary storage. So, in your my.cnf
file:
internal_tmp_disk_storage_engine=MyISAM
I experienced the same issue on a Drupal site. After enabling the Geocoding API on the Google Cloud Platform, works for me. On my setup I require two APIs, Geocoding and Maps Javascript APIs.

The Visitor design pattern works really well for "recursive" structures like directory trees, XML structures, or document outlines.
A Visitor object visits each node in the recursive structure: each directory, each XML tag, whatever. The Visitor object doesn't loop through the structure. Instead Visitor methods are applied to each node of the structure.
Here's a typical recursive node structure. Could be a directory or an XML tag. [If your a Java person, imagine of a lot of extra methods to build and maintain the children list.]
class TreeNode( object ):
def __init__( self, name, *children ):
self.name= name
self.children= children
def visit( self, someVisitor ):
someVisitor.arrivedAt( self )
someVisitor.down()
for c in self.children:
c.visit( someVisitor )
someVisitor.up()
The visit
method applies a Visitor object to each node in the structure. In this case, it's a top-down visitor. You can change the structure of the visit
method to do bottom-up or some other ordering.
Here's a superclass for visitors. It's used by the visit
method. It "arrives at" each node in the structure. Since the visit
method calls up
and down
, the visitor can keep track of the depth.
class Visitor( object ):
def __init__( self ):
self.depth= 0
def down( self ):
self.depth += 1
def up( self ):
self.depth -= 1
def arrivedAt( self, aTreeNode ):
print self.depth, aTreeNode.name
A subclass could do things like count nodes at each level and accumulate a list of nodes, generating a nice path hierarchical section numbers.
Here's an application. It builds a tree structure, someTree
. It creates a Visitor
, dumpNodes
.
Then it applies the dumpNodes
to the tree. The dumpNode
object will "visit" each node in the tree.
someTree= TreeNode( "Top", TreeNode("c1"), TreeNode("c2"), TreeNode("c3") )
dumpNodes= Visitor()
someTree.visit( dumpNodes )
The TreeNode visit
algorithm will assure that every TreeNode is used as an argument to the Visitor's arrivedAt
method.
Mmh ... there are many ways. I answer another network discovery question, and I write a little getting started.
Some tcpip stacks reply to icmp broadcasts. So you can try a PING to your network broadcast address.
For example, you have ip 192.168.1.1 and subnet 255.255.255.0
Note : on step 3. you get the lists of the MAC-to-IP cached entries, so there are also the hosts in your subnet you exchange data to in the last minutes, even if they don't reply to icmp_get.
Note (2) : now I am on linux. I am not sure, but it can be windows doesn't reply to icm_get via broadcast.
Is it the only one device attached to your pc ? Is it a router or another simple pc ?
I would use:
public class Test {
private static final Map<Integer, String> MY_MAP = createMap();
private static Map<Integer, String> createMap() {
Map<Integer, String> result = new HashMap<>();
result.put(1, "one");
result.put(2, "two");
return Collections.unmodifiableMap(result);
}
}
Be aware that caches do not just cache continuous memory. They have multiple lines (at least 4) so discontinous and overlapping memory can often be stored just as efficiently.
What is missing from all the above examples is measured benchmarks. There are many myths about performance. Unless you measure it you do not know. Do not complicate your code unless you have a measured improvement.
I implemented it in the following way. I wanted a generic MakeRequest
method that could call my API and receive content for the body of the request - and also deserialise the response into the desired type. I create a Dictionary<string, string>
object to house the content to be submitted, and then set the HttpRequestMessage
Content
property with it:
Generic method to call the API:
private static T MakeRequest<T>(string httpMethod, string route, Dictionary<string, string> postParams = null)
{
using (var client = new HttpClient())
{
HttpRequestMessage requestMessage = new HttpRequestMessage(new HttpMethod(httpMethod), $"{_apiBaseUri}/{route}");
if (postParams != null)
requestMessage.Content = new FormUrlEncodedContent(postParams); // This is where your content gets added to the request body
HttpResponseMessage response = client.SendAsync(requestMessage).Result;
string apiResponse = response.Content.ReadAsStringAsync().Result;
try
{
// Attempt to deserialise the reponse to the desired type, otherwise throw an expetion with the response from the api.
if (apiResponse != "")
return JsonConvert.DeserializeObject<T>(apiResponse);
else
throw new Exception();
}
catch (Exception ex)
{
throw new Exception($"An error ocurred while calling the API. It responded with the following message: {response.StatusCode} {response.ReasonPhrase}");
}
}
}
Call the method:
public static CardInformation ValidateCard(string cardNumber, string country = "CAN")
{
// Here you create your parameters to be added to the request content
var postParams = new Dictionary<string, string> { { "cardNumber", cardNumber }, { "country", country } };
// make a POST request to the "cards" endpoint and pass in the parameters
return MakeRequest<CardInformation>("POST", "cards", postParams);
}
A much easier and resource friendly approach would be.
import UIKit
@IBDesignable
class CircleDrawView: UIView {
@IBInspectable var borderColor: UIColor = UIColor.red;
@IBInspectable var borderSize: CGFloat = 4
override func draw(_ rect: CGRect)
{
layer.borderColor = borderColor.cgColor
layer.borderWidth = borderSize
layer.cornerRadius = self.frame.height/2
}
}
With Border Color
and Border Size
and the default Background
property you can define the appearance of the circle.
Please note, to draw a circle the view's height and width have to be equal in size.
The code is working for Swift >= 4

.
raise
causes an exception to be raised. Some other languages use the verb 'throw' instead.
It's intended to signal an error situation; it flags that the situation is exceptional to the normal flow.
Raised exceptions can be caught again by code 'upstream' (a surrounding block, or a function earlier on the stack) to handle it, using a try
, except
combination.
It is also possible to do it with an embedded web browser, note however that since this might be a local file, and also because it is not actually the browser directly and there is no DOM so there is no ready state.
Here is the code for the approach I worked out on a win form web browser control:
private void button1_Click(object sender, EventArgs e)
{
webBrowser1.Navigate(@"path\to\file");
}
private void webBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
{
//Progress Changed fires multiple times, however after the Navigated event it is fired only once,
//and at this point it is ready to print
webBrowser1.ProgressChanged += (o, args) =>
{
webBrowser1.Print();//Note this does not print only brings up the print preview dialog
//Should be on a separate task to ensure the main thread
//can fully initialize the print dialog
Task.Factory.StartNew(() =>
{
Thread.Sleep(1000);//We need to wait before we can send enter
//This assumes that the print preview is still in focus
Action g = () =>
{
SendKeys.SendWait("{ENTER}");
};
this.Invoke(g);
});
};
}
You can try this code. This is Simple PHP Image Deleting code from the server.
<form method="post">
<input type="text" name="photoname"> // You can type your image name here...
<input type="submit" name="submit" value="Delete">
</form>
<?php
if (isset($_POST['submit']))
{
$photoname = $_POST['photoname'];
if (!unlink($photoname))
{
echo ("Error deleting $photoname");
}
else
{
echo ("Deleted $photoname");
}
}
?>
If you do it in a migration then you could probably do it like this:
# Make sure no null value exist
MyModel.where(date_column: nil).update_all(date_column: Time.now)
# Change the column to not allow null
change_column :my_models, :date_column, :datetime, null: false
Bootstrap uses CSS3 transitions so progress bars are automatically animated when you set the width of .bar trough javascript / jQuery.
http://jsfiddle.net/3j5Je/ ..see?
This should strip away the date part:
select convert(datetime,convert(float, getdate()) - convert(int,getdate())), getdate()
and return a datetime with a default date of 1900-01-01.
well i found a solution to this problem for who want to work with xCode 4. All what you have to do is importing frameworks from the SimulatorSDK folder /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator4.3.sdk/System/Library/Frameworks
i don't know if it works when you try to test your app on a real iDevice, but i'm sure that it works on simulator.
ENJOY
If you wanted to find all the primes in a range you could do this:
def is_prime(num):
"""Returns True if the number is prime
else False."""
if num == 0 or num == 1:
return False
for x in range(2, num):
if num % x == 0:
return False
else:
return True
num = 0
itr = 0
tot = ''
while itr <= 100:
itr = itr + 1
num = num + 1
if is_prime(num) == True:
print(num)
tot = tot + ' ' + str(num)
print(tot)
Just add while its <=
and your number for the range.
OUTPUT:
2 3 5 7 11 13 17 19 23 29 31 37 41 43 47 53 59 61 67 71 73 79 83 89 97 101
you can display easly in a html page like this
<embed src="path_of_your_pdf/your_pdf_file.pdf" type="application/pdf" height="700px" width="500">
_x000D_
iframe have "sandbox" attribute that may block pop up etc
Here's one way of achieving this. You need to add incremental attribute to your html or it won't work.
window.onload = function() {_x000D_
var tf = document.getElementById('textField');_x000D_
var button = document.getElementById('b');_x000D_
button.disabled = true;_x000D_
var onKeyChange = function textChange() {_x000D_
button.disabled = (tf.value === "") ? true : false;_x000D_
}_x000D_
tf.addEventListener('keyup', onKeyChange);_x000D_
tf.addEventListener('search', onKeyChange);_x000D_
_x000D_
}
_x000D_
<input id="textField" type="search" placeholder="search" incremental="incremental">_x000D_
<button id="b">Go!</button>
_x000D_
Maybe something like this:
import matplotlib.pyplot
import pylab
x = [1,2,3,4]
y = [3,4,8,6]
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
EDIT:
Let me see if I understand you correctly now:
You have:
test1 | test2 | test3
test3 | 1 | 0 | 1
test4 | 0 | 1 | 0
test5 | 1 | 1 | 0
Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.
Let's say you results are stored in a 2-D list:
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
We want to transform them into two variables so we are able to plot them.
And I believe this code will give you what you are looking for:
import matplotlib
import pylab
results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]
x = []
y = []
for ind_1, sublist in enumerate(results):
for ind_2, ele in enumerate(sublist):
if ele == 1:
x.append(ind_1)
y.append(ind_2)
matplotlib.pyplot.scatter(x,y)
matplotlib.pyplot.show()
Notice that I do need to import pylab
, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.
.NET Framework provides many collection classes too. You can use Dictionary in C#. Please find the below msdn link for details and samples http://msdn.microsoft.com/en-us/library/xfhwa508.aspx
if (columnname != a && columnname != b && columnname != c
&& (columnname != A2 || checkbox.checked))
{
"statement 1"
}
Crude, but sufficient for restricting loading larger resources such as video files on phones vs tablet/desktop - simply look for small width or height to cover both orientations. Obviously, if the desktop browser has been resized the below could erroneously detect a phone, but that's fine / close enough for my use case.
Why 480, bcs that's what looks about right based on the info I've found re phone device dimensions.
if(document.body.clientWidth < 480 || document.body.clientHeight < 480) {
//this is a mobile device
}
To store values in shared preferences:
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = sp.edit();
editor.putString("Name","Jayesh");
editor.commit();
To retrieve values from shared preferences:
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(this);
String name = sp.getString("Name", ""); // Second parameter is the default value.
exports.handler = async (event) => {
let query = event.queryStringParameters;
console.log(`id: ${query.id}`);
const response = {
statusCode: 200,
body: "Hi",
};
return response;
};
Well, given your constraints, I think setting overflow: scroll;
on the .page
div is probably your only option. 280 px is pretty narrow, and given your font size, word wrapping alone isn't going to do it. Some words are just long and can't be wrapped. You can either reduce your font size drastically or go with overflow: scroll.
If you are using an MVC framework with routes and actions:
$(document).ready(function () {
$('a[href="' + this.location.pathname + '"]').parent().addClass('active');
});
As illustrated in this answer by Christian Landgren: https://stackoverflow.com/a/13375529/101662
Base on an answer I saw in stackoveflow, I created this LESS mixin (use this link to generate the CSS code):
.max-lines(@lines: 3; @line-height: 1.2) {
overflow: hidden;
text-overflow: ellipsis;
display: -webkit-box;
-webkit-box-orient: vertical;
-webkit-line-clamp: @lines;
line-height: @line-height;
max-height: @line-height * @lines;
}
.example-1 {
.max-lines();
}
.example-2 {
.max-lines(3);
}
.example-3 {
.max-lines(3, 1.5);
}
Have you tried binding the list to the datagridview directly? If not, try that first because it will save you lots of pain. If you have tried it already, please tell us what went wrong so we can better advise you. Data binding gives you different behaviour depending on what interfaces your data object implements. For example, if your data object only implements IEnumerable
(e.g. List
), you will get very basic one-way binding, but if it implements IBindingList
as well (e.g. BindingList
, DataView
), then you get two-way binding.
Just run the following commands,
composer update
Or
composer install
Use:
curl -s -L URL_TO_SCRIPT_HERE | bash
For example:
curl -s -L http://bitly/10hA8iC | bash
The web site likely uses cookies to store your session information. When you run
curl --user user:pass https://xyz.com/a #works ok
curl https://xyz.com/b #doesn't work
curl
is run twice, in two separate sessions. Thus when the second command runs, the cookies set by the 1st command are not available; it's just as if you logged in to page a
in one browser session, and tried to access page b
in a different one.
What you need to do is save the cookies created by the first command:
curl --user user:pass --cookie-jar ./somefile https://xyz.com/a
and then read them back in when running the second:
curl --cookie ./somefile https://xyz.com/b
Alternatively you can try downloading both files in the same command, which I think will use the same cookies.
set the below property:
"npm config set strict-ssl false"
There is a RawFormat property of Image parameter which returns the file format of the image. You might try the following:
// extension method
public static byte[] imageToByteArray(this System.Drawing.Image image)
{
using(var ms = new MemoryStream())
{
image.Save(ms, image.RawFormat);
return ms.ToArray();
}
}
A char array is just that - an array of characters:
A string is a class that contains a char array, but automatically manages it for you. Most string implementations have a built-in array of 16 characters (so short strings don't fragment the heap) and use the heap for longer strings.
You can access a string's char array like this:
std::string myString = "Hello World";
const char *myStringChars = myString.c_str();
C++ strings can contain embedded \0 characters, know their length without counting, are faster than heap-allocated char arrays for short texts and protect you from buffer overruns. Plus they're more readable and easier to use.
However, C++ strings are not (very) suitable for usage across DLL boundaries, because this would require any user of such a DLL function to make sure he's using the exact same compiler and C++ runtime implementation, lest he risk his string class behaving differently.
Normally, a string class would also release its heap memory on the calling heap, so it will only be able to free memory again if you're using a shared (.dll or .so) version of the runtime.
In short: use C++ strings in all your internal functions and methods. If you ever write a .dll or .so, use C strings in your public (dll/so-exposed) functions.
Copy and paste your data into MS Word and use built in text-conversion to "Capitalize Each Word". Compare against your original data to address exceptions. Can't see any way around manually sidestepping "MacDonald" and "IBM" type exceptions but this was how I got it done FWIW.
SELECT (
SELECT COUNT(*)
FROM user_table
) AS tot_user,
(
SELECT COUNT(*)

jQuery Validation Plugin already implements min and max rules, we just need to create an adapter for our custom attribute:
public class MaxAttribute : ValidationAttribute, IClientValidatable
{
private readonly int maxValue;
public MaxAttribute(int maxValue)
{
this.maxValue = maxValue;
}
public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
{
var rule = new ModelClientValidationRule();
rule.ErrorMessage = ErrorMessageString, maxValue;
rule.ValidationType = "max";
rule.ValidationParameters.Add("max", maxValue);
yield return rule;
}
public override bool IsValid(object value)
{
return (int)value <= maxValue;
}
}
Adapter:
$.validator.unobtrusive.adapters.add(
'max',
['max'],
function (options) {
options.rules['max'] = parseInt(options.params['max'], 10);
options.messages['max'] = options.message;
});
Min attribute would be very similar.
See Aaron's. Otherwise:
j=5;i=5
instead of break
.
To set thousand separator, say 123,456.78
you have to use DecimalFormat:
DecimalFormat df = new DecimalFormat("#,###.00");
System.out.println(df.format(new BigDecimal(123456.75)));
System.out.println(df.format(new BigDecimal(123456.00)));
System.out.println(df.format(new BigDecimal(123456123456.78)));
Here is the result:
123,456.75
123,456.00
123,456,123,456.78
Although I set #,###.00
mask, it successfully formats the longer values too.
Note that the comma(,) separator in result depends on your locale. It may be just space( ) for Russian locale.
The quick answer is 2^16 TCP ports, 64K.
The issues with system imposed limits is a configuration issue, already touched upon in previous comments.
The internal implications to TCP is not so clear (to me). Each port requires memory for it's instantiation, goes onto a list and needs network buffers for data in transit.
Given 64K TCP sessions the overhead for instances of the ports might be an issue on a 32-bit kernel, but not a 64-bit kernel (correction here gladly accepted). The lookup process with 64K sessions can slow things a bit and every packet hits the timer queues, which can also be problematic. Storage for in transit data can theoretically swell to the window size times ports (maybe 8 GByte).
The issue with connection speed (mentioned above) is probably what you are seeing. TCP generally takes time to do things. However, it is not required. A TCP connect, transact and disconnect can be done very efficiently (check to see how the TCP sessions are created and closed).
There are systems that pass tens of gigabits per second, so the packet level scaling should be OK.
There are machines with plenty of physical memory, so that looks OK.
The performance of the system, if carefully configured should be OK.
The server side of things should scale in a similar fashion.
I would be concerned about things like memory bandwidth.
Consider an experiment where you login to the local host 10,000 times. Then type a character. The entire stack through user space would be engaged on each character. The active footprint would likely exceed the data cache size. Running through lots of memory can stress the VM system. The cost of context switches could approach a second!
This is discussed in a variety of other threads: https://serverfault.com/questions/69524/im-designing-a-system-to-handle-10000-tcp-connections-per-second-what-problems
Have a look at the EditorConfig plugin.
By using the plugin you can have settings specific for various projects. Visual Studio Code also has IntelliSense built-in for .editorconfig files.
Modern processors are too fast to register the running time. Hence it may return zero. In this case, the time you started and ended is too small and therefore both the times are the same after round of.
While the selected answer is strictly correct, I believe I understand what the OP is trying to get at here as I had a similar issue.
I had a TimeSpan which I wished to display in a grid control (as just hh:mm) but the grid didn't appear to understand TimeSpan, only DateTime . The OP has a similar scenario where only the TimeSpan is the relevant part but didn't consider the necessity of adding the DateTime reference point.
So, as indicated above, I simply added DateTime.MinValue (though any date will do) which is subsequently ignored by the grid when it renders the timespan as a time portion of the resulting date.
You are all wrong! Why? Because all you need is this code to work:
(image View) / C# Img is : your Image box
Keep this as is, without change ("ms-appx:///) this is code not your app name Images is your folder in your project you can change it. dog.png is your file in your folder, as well as i do my folder 'Images' and file 'dog.png' So the uri is :"ms-appx:///Images/dog.png" and my code :
private void Button_Click(object sender, RoutedEventArgs e)
{
img.Source = new BitmapImage(new Uri("ms-appx:///Images/dog.png"));
}
c# 7.0 lets you do this:
var tupleList = new List<(int, string)>
{
(1, "cow"),
(5, "chickens"),
(1, "airplane")
};
If you don't need a List
, but just an array, you can do:
var tupleList = new(int, string)[]
{
(1, "cow"),
(5, "chickens"),
(1, "airplane")
};
And if you don't like "Item1" and "Item2", you can do:
var tupleList = new List<(int Index, string Name)>
{
(1, "cow"),
(5, "chickens"),
(1, "airplane")
};
or for an array:
var tupleList = new (int Index, string Name)[]
{
(1, "cow"),
(5, "chickens"),
(1, "airplane")
};
which lets you do: tupleList[0].Index
and tupleList[0].Name
Framework 4.6.2 and below
You must install System.ValueTuple
from the Nuget Package Manager.
Framework 4.7 and above
It is built into the framework. Do not install System.ValueTuple
. In fact, remove it and delete it from the bin directory.
note: In real life, I wouldn't be able to choose between cow, chickens or airplane. I would be really torn.
I recently needed to do this and I came up with this
-- GROUP_CONCAT turns all the rows into 1
-- @q:= stores all the kill commands to a variable
select @q:=GROUP_CONCAT(CONCAT('KILL ',ID) SEPARATOR ';')
FROM information_schema.processlist
-- If you don't need it, you can remove the WHERE command altogether
WHERE user = 'user';
-- Creates statement and execute it
PREPARE stmt FROM @q;
EXECUTE stmt;
DEALLOCATE PREPARE stmt;
That way, you don't need to store to file and run all queries with a single command.
Their is a tool called indent
. You can download it with apt-get install indent
, then run indent my_program.c
.
I'd say it depends on what you need it for:
If you need it just to get 3 columns layout, I'd suggest to do it with float
.
If you need it for menu, you can use inline-block
. For the whitespace problem, you can use few tricks as described by Chris Coyier here http://css-tricks.com/fighting-the-space-between-inline-block-elements/.
If you need to make a multiple choice option, which the width needs to spread evenly inside a specified box, then I'd prefer display: table
. This will not work correctly in some browsers, so it depends on your browser support.
Lastly, what might be the best method is using flexbox
. The spec for this has changed few times, so it's not stable just yet. But once it has been finalized, this will be the best method I reckon.
Another option could be:
var initial = function() {
console.log( 'initial function!' );
}
var iWantToExecuteThisOneToo = function () {
console.log( 'the other function that i wanted to execute!' );
}
function extendFunction( oldOne, newOne ) {
return (function() {
oldOne();
newOne();
})();
}
var extendedFunction = extendFunction( initial, iWantToExecuteThisOneToo );

Floating-point numbers, also known as real numbers, are used when evaluating expressions that require fractional precision. For example, calculations such as square root, or transcendentals such as sine and cosine, result in a value whose precision requires a floating-point type. Java implements the standard (IEEE–754) set of floatingpoint types and operators. There are two kinds of floating-point types, float and double, which represent single- and double-precision numbers, respectively. Their width and ranges are shown here:
Name Width in Bits Range
double 64 1 .7e–308 to 1.7e+308
float 32 3 .4e–038 to 3.4e+038
float
The type float specifies a single-precision value that uses 32 bits of storage. Single precision is faster on some processors and takes half as much space as double precision, but will become imprecise when the values are either very large or very small. Variables of type float are useful when you need a fractional component, but don't require a large degree of precision.
Here are some example float variable declarations:
float hightemp, lowtemp;
double
Double precision, as denoted by the double keyword, uses 64 bits to store a value. Double precision is actually faster than single precision on some modern processors that have been optimized for high-speed mathematical calculations. All transcendental math functions, such as sin( ), cos( ), and sqrt( ), return double values. When you need to maintain accuracy over many iterative calculations, or are manipulating large-valued numbers, double is the best choice.
A scalar always holds a single element. Whatever is in a scalar variable is always a scalar. A reference is a scalar value.
If you want to know if it is a reference, you can use ref
. If you want to know the reference type,
you can use the reftype
routine from Scalar::Util.
If you want to know if it is an object, you can use the blessed
routine from Scalar::Util. You should never care what the blessed package is, though. UNIVERSAL
has some methods to tell you about an object: if you want to check that it has the method you want to call, use can
; if you want to see that it inherits from something, use isa
; and if you want to see it the object handles a role, use DOES
.
If you want to know if that scalar is actually just acting like a scalar but tied to a class, try tied
. If you get an object, continue your checks.
If you want to know if it looks like a number, you can use looks_like_number
from Scalar::Util. If it doesn't look like a number and it's not a reference, it's a string. However, all simple values can be strings.
If you need to do something more fancy, you can use a module such as Params::Validate.
In Bootstrap 4 for Horizontal element you can use .row
with .col-*-*
classes to specify the width of your labels and controls. see this link.
And if you want to display a series of labels, form controls, and buttons on a single horizontal row you can use .form-inline

@David, thanks for the recommendation! @fluid_chelsea, I've just released Any+Time(TM) version 3.x which uses jQuery instead of Prototype and has a much-improved interface, so I hope it now meets your needs:
Any problems, please let me know via the comment link on my website!
I had the same problem.please do the following it may help you: By Default List View Threshold set at only 5,000 items this is because of Sharepoint server performance.

To get a type that implements io.Reader
from a []byte
slice, you can use bytes.NewReader
in the bytes
package:
r := bytes.NewReader(byteData)
This will return a value of type bytes.Reader
which implements the io.Reader
(and io.ReadSeeker
) interface.
Don't worry about them not being the same "type". io.Reader
is an interface and can be implemented by many different types. To learn a little bit more about interfaces in Go, read Effective Go: Interfaces and Types.
Note that since git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1 and release note, June 2012) mentions:
"
git push --recurse-submodules
" learned to optionally look into the histories of submodules bound to the superproject and push them out.
Probably done after this patch and the --on-demand
option:
recurse-submodules=<check|on-demand>::
Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.
- If
check
is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
Otherwise the push will be aborted and exit with non-zero status.- If
on-demand
is used, all submodules that changed in the revisions to be pushed will be pushed.
If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.
So you could push everything in one go with (from the parent repo) a:
git push --recurse-submodules=on-demand
This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.
With git 2.7 (January 2016), a simple git push will be enough to push the parent repo... and all its submodules.
See commit d34141c, commit f5c7cd9 (03 Dec 2015), commit f5c7cd9 (03 Dec 2015), and commit b33a15b (17 Nov 2015) by Mike Crowe (mikecrowe

push
: addrecurseSubmodules
config optionThe
--recurse-submodules
command line parameter has existed for some time but it has no config file equivalent.Following the style of the corresponding parameter for
git fetch
, let's inventpush.recurseSubmodules
to provide a default for this parameter.
This also requires the addition of--recurse-submodules=no
to allow the configuration to be overridden on the command line when required.The most straightforward way to implement this appears to be to make
push
use code insubmodule-config
in a similar way tofetch
.
The git config
doc now include:
push.recurseSubmodules
:Make sure all submodule commits used by the revisions to be pushed are available on a remote-tracking branch.
- If the value is '
check
', then Git will verify that all submodule commits that changed in the revisions to be pushed are available on at least one remote of the submodule. If any commits are missing, the push will be aborted and exit with non-zero status.- If the value is '
on-demand
' then all submodules that changed in the revisions to be pushed will be pushed. If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status. -- If the value is '
no
' then default behavior of ignoring submodules when pushing is retained.You may override this configuration at time of push by specifying '
--recurse-submodules=check|on-demand|no
'.
So:
git config push.recurseSubmodules on-demand
git push
Git 2.12 (Q1 2017)
git push --dry-run --recurse-submodules=on-demand
will actually work.
See commit 0301c82, commit 1aa7365 (17 Nov 2016) by Brandon Williams (mbrandonw
).
(Merged by Junio C Hamano -- gitster
-- in commit 12cf113, 16 Dec 2016)
push run with --dry-run
doesn't actually (Git 2.11 Dec. 2016 and lower/before) perform a dry-run when push is configured to push submodules on-demand.
Instead all submodules which need to be pushed are actually pushed to their remotes while any updates for the superproject are performed as a dry-run.
This is a bug and not the intended behaviour of a dry-run.Teach
push
to respect the--dry-run
option when configured to recursively push submodules 'on-demand'.
This is done by passing the--dry-run
flag to the child process which performs a push for a submodules when performing a dry-run.
And still in Git 2.12, you now havea "--recurse-submodules=only
" option to push submodules out without pushing the top-level superproject.

You might need to build an inverted index for your database. It is assured to be pretty fast.
if you want to change default:
for bootstrap 3.x:
$.fn.modal.prototype.constructor.Constructor.DEFAULTS.backdrop = 'static';
$.fn.modal.prototype.constructor.Constructor.DEFAULTS.keyboard = false;
for bootstrap 4.x:
$.fn.modal.prototype.constructor.Constructor.Default.backdrop = 'static';
$.fn.modal.prototype.constructor.Constructor.Default.keyboard = false;
Yes, you've downloaded and installed the Java Runtime Environment (JRE) instead of the Java Development Kit (JDK). The latter has the tools.jar, java.exe, javac.exe, etc.
This happens when Eclipse screws up. To fix it, delete all the files in:

cesards's answer is correct, but only for API > 15. For lower API versions I decided to use getRunningTasks()
method:
private boolean isAppInForeground(Context context)
{
if (android.os.Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP)
{
ActivityManager am = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE);
ActivityManager.RunningTaskInfo foregroundTaskInfo = am.getRunningTasks(1).get(0);
String foregroundTaskPackageName = foregroundTaskInfo.topActivity.getPackageName();
return foregroundTaskPackageName.toLowerCase().equals(context.getPackageName().toLowerCase());
}
else
{
ActivityManager.RunningAppProcessInfo appProcessInfo = new ActivityManager.RunningAppProcessInfo();
ActivityManager.getMyMemoryState(appProcessInfo);
if (appProcessInfo.importance == IMPORTANCE_FOREGROUND || appProcessInfo.importance == IMPORTANCE_VISIBLE)
{
return true;
}
KeyguardManager km = (KeyguardManager) context.getSystemService(Context.KEYGUARD_SERVICE);
// App is foreground, but screen is locked, so show notification
return km.inKeyguardRestrictedInputMode();
}
}
Please, let me know if it works for you all.
You can also use Prototype's Object.inspect() method, which "Returns the debug-oriented string representation of the object".

I know this question is old, however I ran into this problem on Windows 8.1 while trying to use .htaccess files for rewriting. My solution was simple, I forgot to modify the following line in httpd.conf

LoadModule rewrite_module modules/mod_rewrite.so
Restarted the apache monitor, now all works well. Just posting this as an answer because someone in the future may run across the same issue with a simple fix.

Not exactly what the user asked, but an easy way to just count unique values:
Google introduced a new function to count unique values in just one step, and you can use this as an input for other formulas:
=COUNTUNIQUE(A1:B10)
Using this,
String s = "03/24/2013 21:54";
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("MM/dd/yyyy HH:mm");
try
{
Date date = simpleDateFormat.parse(s);
System.out.println("date : "+simpleDateFormat.format(date));
}
catch (ParseException ex)
{
System.out.println("Exception "+ex);
}

return Stream.

I put the following javascript in the page header and it seems to work. It detects when the browser does not support showModalDialog and attaches a custom method that uses window.open, parses the dialog specs (height, width, scroll, etc.), centers on opener and sets focus back to the window (if focus is lost). Also, it uses the URL as the window name so that a new window is not opened each time. If you are passing window args to the modal you will need to write some additional code to fix that. The popup is not modal but at least you don't have to change a lot of code. Might need some work for your circumstances.
<script type="text/javascript">
// fix for deprecated method in Chrome 37
if (!window.showModalDialog) {
window.showModalDialog = function (arg1, arg2, arg3) {
var w;
var h;
var resizable = "no";
var scroll = "no";
var status = "no";
// get the modal specs
var mdattrs = arg3.split(";");
for (i = 0; i < mdattrs.length; i++) {
var mdattr = mdattrs[i].split(":");
var n = mdattr[0];
var v = mdattr[1];
if (n) { n = n.trim().toLowerCase(); }
if (v) { v = v.trim().toLowerCase(); }
if (n == "dialogheight") {
h = v.replace("px", "");
} else if (n == "dialogwidth") {
w = v.replace("px", "");
} else if (n == "resizable") {
resizable = v;
} else if (n == "scroll") {
scroll = v;
} else if (n == "status") {
status = v;
}
}
var left = window.screenX + (window.outerWidth / 2) - (w / 2);
var top = window.screenY + (window.outerHeight / 2) - (h / 2);
var targetWin = window.open(arg1, arg1, 'toolbar=no, location=no, directories=no, status=' + status + ', menubar=no, scrollbars=' + scroll + ', resizable=' + resizable + ', copyhistory=no, width=' + w + ', height=' + h + ', top=' + top + ', left=' + left);

The Problem is the Container that gets the smallest possible size.
Just give a width:
to the Container (in red) and you are done.

If you want to test explicitly for valid JSON (as opposed to the absence of the returned value false

Here is the one-liner version getting the client's IP address:

Notes:
@
, it suppresses the PHP notices.Value from HTTP_X_FORWARDED_FOR
may consist multiple addresses separated by comma, so if you prefer to get the first one, you can use the following method:
current(explode(',', @$_SERVER['HTTP_X_FORWARDED_FOR']))

@Baxter's is mostly correct but it is missing one important Windows-specific detail.
Subversion's runtime configuration area is stored in the %APPDATA%\Subversion\
directory. The files are config
and servers
.
However, in addition to text-based configuration files, Subversion clients can use Windows Registry to store the client settings. It makes it possible to modify the settings with PowerShell in a convenient manner, and also distribute these settings to user workstations in Active Directory environment via AD Group Policy. See SVNBook | Configuration and the Windows Registry (you can find examples and a sample *.reg
file there).
You can use that and adjust the time you want to launch 1= onload 2000= 2 sec
$(document).ready(function(){
$('#click').click(function(){
alert('button clicked');
});
// set time out 2 sec
setTimeout(function(){
$('#click').trigger('click');
}, 2000);
});

I got the same problem.

You typically have to do this in a single syscall, or else you will get a race condition.
This will open for reading and writing, creating the file if necessary.
FILE *fp = fopen("scores.dat", "ab+");
If you want to read it and then write a new version from scratch, then do it as two steps.
FILE *fp = fopen("scores.dat", "rb");
if (fp) {
read_scores(fp);
}
// Later...
// truncates the file
FILE *fp = fopen("scores.dat", "wb");
if (!fp)
error();
write_scores(fp);
The proper way is to do a Time.now.getutc.to_i
to get the proper timestamp amount as simply displaying the integer need not always be same as the utc timestamp due to time zone differences.
My answer is very similar to the one from @biscoop, but I am going to elaborate a bit as it may apply to the question or to other people.
I had a .xls that was an extraction from one of our webapps. The Excel connection would not work (error message: "no tables or views could be loaded"). As a side note, when opening the file, there would be a warning stating that the file was from an online source and that the content needed activation.
I tried to save the same file as an .xlsx and it worked. I tried to save the same file with another name as an .xls and it worked too. So as a last test I only opened the source .xls file, clicking save and the connection worked.
Short answer: just try and see if opening the file and saving does the trick.
If you can, I strongly suggest you tar
and bzip
(or gzip
, whatever floats your boat) the directory on the remote machine—for a directory of any significant size, the bandwidth savings will probably be worth the time to zip/unzip.
If you go to the Flat file connection manager under Advanced and Look at the "OutputColumnWidth" description's ToolTip It will tell you that Composit characters may use more spaces. So the "é" in "Société" most likely occupies more than one character.
EDIT: Here's something about it: http://en.wikipedia.org/wiki/Precomposed_character
There could be many reason why document.getElementById
doesn't work
You have an invalid ID
ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods ("."). (resource: What are valid values for the id attribute in HTML?)
you used some id that you already used as <meta>
name in your header (e.g. copyright, author... ) it looks weird but happened to me: if your 're using IE take a look at
(resource: http://www.phpied.com/getelementbyid-description-in-ie/)
you're targeting an element inside a frame or iframe. In this case if the iframe loads a page within the same domain of the parent you should target the contentdocument
before looking for the element
(resource: Calling a specific id inside a frame)
you're simply looking to an element when the node is not effectively loaded in the DOM, or maybe it's a simple misspelling
I doubt you used same ID twice or more: in that case document.getElementById
should return at least the first element

See this link, following is quoted from there:
A BufferedReader is a simple class meant to efficiently read from the underling stream. Generally, each read request made of a Reader like a FileReader causes a corresponding read request to be made to underlying stream. Each invocation of read() or readLine() could cause bytes to be read from the file, converted into characters, and then returned, which can be very inefficient. Efficiency is improved appreciably if a Reader is warped in a BufferedReader.
BufferedReader is synchronized, so read operations on a BufferedReader can safely be done from multiple threads.
A scanner on the other hand has a lot more cheese built into it; it can do all that a BufferedReader can do and at the same level of efficiency as well. However, in addition a Scanner can parse the underlying stream for primitive types and strings using regular expressions. It can also tokenize the underlying stream with the delimiter of your choice. It can also do forward scanning of the underlying stream disregarding the delimiter!
A scanner however is not thread safe, it has to be externally synchronized.
The choice of using a BufferedReader or a Scanner depends on the code you are writing, if you are writing a simple log reader Buffered reader is adequate. However if you are writing an XML parser Scanner is the more natural choice.
Even while reading the input, if want to accept user input line by line and say just add it to a file, a BufferedReader is good enough. On the other hand if you want to accept user input as a command with multiple options, and then intend to perform different operations based on the command and options specified, a Scanner will suit better.
The onunload event won't fire if the onload event did not fire. Unfortunately the onload event waits for all binary content (e.g. images) to load, and inline scripts run before the onload event fires. DOMContentLoaded fires when the page is visible, before onload does. And it is now standard in HTML 5, and you can test for browser support but note this requires the <!DOCTYPE html>
(at least in Chrome). However, I can not find a corresponding event for unloading the DOM. And such a hypothetical event might not work because some browsers may keep the DOM around to perform the "restore tab" feature.
The only potential solution I found so far is the Page Visibility API, which appears to require the <!DOCTYPE html>
.
There are a bunch of answers that mention pysftp, so in the event that you want a context manager wrapper around pysftp, here is a solution that is even less code that ends up looking like the following when used
path = "sftp://user:p@[email protected]/path/to/file.txt"
# Read a file
with open_sftp(path) as f:
s = f.read()
print s
# Write to a file
with open_sftp(path, mode='w') as f:
f.write("Some content.")
The (fuller) example: http://www.prschmid.com/2016/09/simple-opensftp-context-manager-for.html
This context manager happens to have auto-retry logic baked in in the event you can't connect the first time around (which surprisingly happens more often than you'd expect in a production environment...)

You can't select a sheet in a non-active workbook.
You must first activate the workbook, then you can select the sheet.
workbooks("A").activate
workbooks("A").worksheets("B").select
When you use Activate it automatically activates the workbook.
Note you can select >1 sheet in a workbook:
activeworkbook.sheets(array("sheet1","sheet3")).select
but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.
Use this code:
let registrationDateString = "2008-10-06 00:00:00"
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd hh:mm:ss"
if let registrationDate = dateFormatter.date(from: registrationDateString) {
let currentDate = Date()
let dateDifference = Calendar.current.dateComponents([.day, .month, .year],
from: registrationDate,
to: currentDate)
print("--------------------- Result: \(dateDifference.year ?? 0) years \(dateDifference.month ?? 0) months and \(dateDifference.day ?? 0) days")
} else {
print("--------------------- No result")
}
Output is: Result: 10 years 1 months and 18 days
To add up on the selected answer, I have been testing a new option that is working too using jinja2 and flask:
@app.route('/')
def my_view():
data = [1, 2, 3, 4, 5]
return render_template('index.html', data=data)
The template:
<script>
console.log( {{ data | tojson }} )
</script>
the output of the rendered template:
<script>
console.log( [1, 2, 3, 4] )
</script>
The safe
could be added but as well like {{ data | tojson | safe }}
to avoid html escape but it is working without too.
This is how i do it.
$("input[name='title']").on({
"change keyup": function(e) {
var slug = $(this).val().split(" ").join("-").toLowerCase();
$("input[name='slug']").val(slug);
},
});
We implemented a ngModelChange observable directive that sends all model changes through an event emitter that you instantiate in your own component. You simply have to bind your event emitter to the directive.
See: https://github.com/atomicbits/angular2-modelchangeobservable
In html, bind your event emitter (countryChanged in this example):
<input [(ngModel)]="country.name"
[modelChangeObservable]="countryChanged"
placeholder="Country"
name="country" id="country"></input>
In your typescript component, do some async operations on the EventEmitter:
import ...
import {ModelChangeObservable} from './model-change-observable.directive'
@Component({
selector: 'my-component',
directives: [ModelChangeObservable],
providers: [],
templateUrl: 'my-component.html'
})
export class MyComponent {
@Input()
country: Country
selectedCountries:Country[]
countries:Country[] = <Country[]>[]
countryChanged:EventEmitter<string> = new EventEmitter<string>()
constructor() {
this.countryChanged
.filter((text:string) => text.length > 2)
.debounceTime(300)
.subscribe((countryName:string) => {
let query = new RegExp(countryName, 'ig')
this.selectedCountries = this.countries.filter((country:Country) => {
return query.test(country.name)
})
})
}
}
Prompted by this question, may I present another alternative which might be a bit nicer to use and will look the same for both methods and functions:
@static_var2('seed',0)
def funccounter(statics, add=1):
statics.seed += add
return statics.seed
print funccounter() #1
print funccounter(add=2) #3
print funccounter() #4
class ACircle(object):
@static_var2('seed',0)
def counter(statics, self, add=1):
statics.seed += add
return statics.seed
c = ACircle()
print c.counter() #1
print c.counter(add=2) #3
print c.counter() #4
d = ACircle()
print d.counter() #5
print d.counter(add=2) #7
print d.counter() #8
If you like the usage, here's the implementation:
class StaticMan(object):
def __init__(self):
self.__dict__['_d'] = {}
def __getattr__(self, name):
return self.__dict__['_d'][name]
def __getitem__(self, name):
return self.__dict__['_d'][name]
def __setattr__(self, name, val):
self.__dict__['_d'][name] = val
def __setitem__(self, name, val):
self.__dict__['_d'][name] = val
def static_var2(name, val):
def decorator(original):
if not hasattr(original, ':staticman'):
def wrapped(*args, **kwargs):
return original(getattr(wrapped, ':staticman'), *args, **kwargs)
setattr(wrapped, ':staticman', StaticMan())
f = wrapped
else:
f = original #already wrapped
getattr(f, ':staticman')[name] = val
return f
return decorator
As Scala was mentioned, Kotlin is also worth mentioning. In Kotlin function parameters can have default values as well and they can even refer to other parameters:
fun read(b: Array<Byte>, off: Int = 0, len: Int = b.size) {
...
}
Like Scala, Kotlin runs on the JVM and can be easily integrated into existing Java projects.
FindByAttributeValue("Attribute-Name", "Attribute-Value");
p.s. if you know exact element-type, you add 3rd parameter (i.e.div, a, p ...etc...
):
FindByAttributeValue("Attribute-Name", "Attribute-Value", "div");
but at first, define this function:
function FindByAttributeValue(attribute, value, element_type) {
element_type = element_type || "*";
var All = document.getElementsByTagName(element_type);
for (var i = 0; i < All.length; i++) {
if (All[i].getAttribute(attribute) == value) { return All[i]; }
}
}
p.s. updated per comments recommendations.

A very simple way to do it is:
list1=['']
j=0
for i in com_list:
if j==0:
list1[0]=(i['value'])
else:
list1.append(i['value'])
j+=1
Output:
['apple', 'banana', 'cars']
It is SUBSTITUTE(B1," ","")
, not REPLACE(xx;xx;xx)

ArrayList<String> data = new ArrayList<String>();
try {
// jsonArray looks like { "everything" : [{}, {},] }
JSONArray jsonArray = jsonObject.getJSONArray( "everything" );
int number = jsonArray.length(); //How many rows have got from the database?
Log.i( Constants.INFORMATION, "Number of ows returned: " + Integer.toString( number ) );
// Array elements look like this
//{"success":1,"error":0,"name":"English One","owner":"Tutor","description":"Initial Alert","posted":"2013-08-09 15:35:40"}
for( int element = 0; element < number; element++ ) { //visit each element
JSONObject jsonObject_local = jsonArray.getJSONObject( element );
// Overkill on the error/success checking
Log.e("JSON SUCCESS", Integer.toString( jsonObject_local.getInt(Constants.KEY_SUCCESS) ) );
Log.e("JSON ERROR", Integer.toString( jsonObject_local.getInt(Constants.KEY_ERROR) ) );

Each database's implementation but you can probably guess that they all solve common problems in more or less the same way. If you are using MSSQL have a look at the execution plan that is generated. You can do this by turning on the profiler and executions plans. This will give you a text version when you run the command.
I am not sure what version of MSSQL you are using but you can get a graphical one in SQL Server 2000 in the query analyzer. I am sure that this functionality is lurking some where in SQL Server Studio Manager in later versions.
Have a look at the exeuction plan. As far as possible avoid table scans unless of course your table is small in which case a table scan is faster than using an index. Read up on the different join operations that each different scenario produces.
I didn't see my thoughts repeated already, so I will suggest that you look at string.Trim
in the Microsoft documentation for C# you can add a character to be trimmed instead of simply trimming empty spaces:
string withQuotes = "\"hellow\"";
string withOutQotes = withQuotes.Trim('"');
should result in withOutQuotes being "hello"
instead of ""hello""
Size of a pointer should be 8 byte on any 64-bit C/C++ compiler, but not necessarily size of int.
If I Understood correctly you need to view the .db file that you extracted from internal storage of Emulator. If that's the case use this
http://sourceforge.net/projects/sqlitebrowser/
to view the db.
You can also use a firefox extension
https://addons.mozilla.org/en-us/firefox/addon/sqlite-manager/
EDIT: For online tool use : https://sqliteonline.com/
If you use constants then you have no choice:
const numbers = [1, 2, 3]
You can not reasign:
numbers = []
You can only truncate:
numbers.length = 0

It's a bit weird that I placed the start stop restart in a separate case but it should work
From Django docs :
To handle both of these situations, Django has a consistent way of processing filter() calls. Everything inside a single filter() call is applied simultaneously to filter out items matching all those requirements. Successive filter() calls further restrict the set of objects, but for multi-valued relations, they apply to any object linked to the primary model, not necessarily those objects that were selected by an earlier filter() call.
filter()
are applied simultaneously.
That means that doing :objs = Mymodel.objects.filter(a=True, b=False)
will return a queryset with raws from model Mymodel
where a=True
AND b=False
.
filter()
, in some case, will provide the same result. Doing :objs = Mymodel.objects.filter(a=True).filter(b=False)
will return a queryset with raws from model Mymodel
where a=True
AND b=False
too. Since you obtain "first" a queryset with records which have a=True
and then it's restricted to those who have b=False
at the same time.
filter()
comes when there are multi-valued relations
, which means you are going through other models (such as the example given in the docs, between Blog and Entry models). It is said that in that case (...) they apply to any object linked to the primary model, not necessarily those objects that were selected by an earlier filter() call.
Which means that it applies the successives filter()
on the target model directly, not on previous filter()
If I take the example from the docs :
Blog.objects.filter(entry__headline__contains='Lennon').filter(entry__pub_date__year=2008)
remember that it's the model Blog
that is filtered, not the Entry
. So it will treat the 2 filter()
independently.
It will, for instance, return a queryset with Blogs, that have entries that contain 'Lennon' (even if they are not from 2008) and entries that are from 2008 (even if their headline does not contain 'Lennon')
THIS ANSWER goes even further in the explanation. And the original question is similar.
And now for something completely different. The following assumes arial font, and makes a wild guess based on a linear interpolation of character vs width.
// Returns the size in PICA of the string, given space is 200 and 'W' is 1000.
// see https://p2p.wrox.com/access/32197-calculate-character-widths.html
static int picaSize(String s)
{
// the following characters are sorted by width in Arial font
String lookup = " .:,;'^`!|jl/\\i-()JfIt[]?{}sr*a\"ce_gFzLxkP+0123456789<=>~qvy$SbduEphonTBCXY#VRKZN%GUAHD@OQ&wmMW";
int result = 0;
for (int i = 0; i < s.length(); ++i)
{
int c = lookup.indexOf(s.charAt(i));
result += (c < 0 ? 60 : c) * 7 + 200;
}
return result;
}
Interesting, but perhaps not very practical.
I had the same issue, I changed Tools -> Options -> Projects and Solutions/Build and Run -> MSBuild project build log file verbosity[Diagnostic]. This option shows error in log, due to some reasons my VS not showing Error in Errors tab!
Do above settings and in output copy in notepad/texteditor and search for error. It will show you all errors.
If your jQuery page isn't being loaded from http://localhost:54473
then this issue is probably because you're trying to make cross-domain request.
Update 1 Take a look at this blog post.
Update 2 If this is indeed the problem (and I suspect it is), you might want to check out JSONP as a solution. Here are a few links that might help you get started:
Some generic help:
gdb start GDB, with no debugging les
gdb program begin debugging program
gdb program core debug coredump core produced by program
gdb --help describe command line options
First of all, find the directory where the corefile is generated.
Then use ls -ltr
command in the directory to find the latest generated corefile.
To load the corefile use
gdb binary path of corefile
This will load the corefile.
Then you can get the information using the bt
command.
For a detailed backtrace use bt full
.
To print the variables, use print variable-name
or p variable-name
To get any help on GDB, use the help
option or use apropos search-topic
Use frame frame-number
to go to the desired frame number.
Use up n
and down n
commands to select frame n frames up and select frame n frames down respectively.
To stop GDB, use quit
or q
.
my python is build from source, the cause is missing options when exec configure python version:3.7.4

If you are using wiindows OS (I am using windows 10 ) just type
where python
in command prompt ( cmd )
It will show you the directory where you have installed .
npm uninstall -g create-react-app
could be an answer in some cases, but not in mine.
You should manually delete your create-react-app located at ~/.node/bin/
or /usr/bin/
(just type which create-react-app
and remove it from locations you saw using rm -rf
), next just run npm i -g create-react-app
.
After that create-react-app
will be working correctly.
Change this:
public FrameForm() {
initComponents();
}
to this:
public FrameForm() {
initComponents();
this.setLocationRelativeTo(null);
}
You need to float all the buttons to left and make sure its width to fit within outer container.
CSS:
.btn{
float:left;
}
HTML:
<button type="submit" class="btn" onClick="return false;" >Save</button>
<button type="submit" class="btn" onClick="return false;">Publish</button>
<button class="btn">Back</button>
Did you try passwd -d root
? Most likely, this will do what you want.
You can also manually edit /etc/shadow
: (Create a backup copy. Be sure that you can log even if you mess up, for example from a rescue system.) Search for "root". Typically, the root entry looks similar to
root:$X$SK5xfLB1ZW:0:0...
There, delete the second field (everything between the first and second colon):
root::0:0...
Some systems will make you put an asterisk (*) in the password field instead of blank, where a blank field would allow no password (CentOS 8 for example)
root:*:0:0...
Save the file, and try logging in as root. It should skip the password prompt. (Like passwd -d
, this is a "no password" solution. If you are really looking for a "blank password", that is "ask for a password, but accept if the user just presses Enter", look at the manpage of mkpasswd
, and use mkpasswd
to create the second field for the /etc/shadow.)
using pymsql if it helps
import pymysql
import csv
db = pymysql.connect("localhost","root","12345678","data" )
cursor = db.cursor()
csv_data = csv.reader(open('test.csv'))
next(csv_data)
for row in csv_data:
cursor.execute('INSERT INTO PM(col1,col2) VALUES(%s, %s)',row)
db.commit()
cursor.close()
Try using Joda Time instead of standard java.util.Date classes. Joda Time library has much better API for handling dates.
DateTime dt = new DateTime(); // current time
int month = dt.getMonth(); // gets the current month
int hours = dt.getHourOfDay(); // gets hour of day
See this question for pros and cons of using Joda Time library.
Joda Time may also be included to some future version of Java as a standard component, see JSR-310.
If you must use traditional java.util.Date and java.util.Calendar classes, see their JavaDoc's for help (java.util.Calendar and java.util.Date).
You can use the traditional classes like this to fetch fields from given Date instance.
Date date = new Date(); // given date
Calendar calendar = GregorianCalendar.getInstance(); // creates a new calendar instance
calendar.setTime(date); // assigns calendar to given date
calendar.get(Calendar.HOUR_OF_DAY); // gets hour in 24h format
calendar.get(Calendar.HOUR); // gets hour in 12h format
calendar.get(Calendar.MONTH); // gets month number, NOTE this is zero based!
It's worth noting that Java can overload a method such as abs
so that it works with an integer or a double. In C, overloading doesn't exist, so you need different functions for integer versus double.
Using for:
for each in "${alpha[@]}"
do
echo "$each"
done
Using history; note this will fail if your values contain !
:
history -p "${alpha[@]}"
Using basename; note this will fail if your values contain /
:
basename -a "${alpha[@]}"
Using shuf; note that results might not come out in order:
shuf -e "${alpha[@]}"
You need to make it a generic method, like this:
public static T ConfigSetting<T>(string settingName)
{
return /* code to convert the setting to T... */
}
But the caller will have to specify the type they expect. You could then potentially use Convert.ChangeType
, assuming that all the relevant types are supported:
public static T ConfigSetting<T>(string settingName)
{
object value = ConfigurationManager.AppSettings[settingName];
return (T) Convert.ChangeType(value, typeof(T));
}
I'm not entirely convinced that all this is a good idea, mind you...
I struggled with the same permission denied error apparently due to
key_parse_private2: missing begin marker
In my situation the cause was the ssh config file of the current user (~/.ssh/config).
Using the following:
ssh -i ~/myKey.pem ec2-user@<IP address> -v 'exit'
The initial output showed:
debug1: Reading configuration data /home/ec2-user/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 56: Applying options for *
debug1: Hostname has changed; re-reading configuration
debug1: Reading configuration data /home/ec2-user/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
... many debug lines cut here ...
debug1: Next authentication method: publickey
debug1: Trying private key: /home/ec2-user/somekey.pem
debug1: key_parse_private2: missing begin marker
debug1: read PEM private key done: type RSA
debug1: Authentications that can continue: publickey
debug1: No more authentication methods to try.
The third line above is where the problem actual was identified; however, I looked for at the debug message four lines from the bottom (above) and was misled. There isn't a problem with the key but I tested it and compared other configurations.
My user ssh config file reset the host via an unintended global setting as shown below. The first Host line should not have been a comment.
$ cat config
StrictHostKeyChecking=no
#Host myAlias
user ec2-user
Hostname bitbucket.org
# IdentityFile ~/.ssh/somekey
# IdentitiesOnly yes
Host my2ndAlias
user myOtherUser
Hostname bitbucket.org
IdentityFile ~/.ssh/my2ndKey
IdentitiesOnly yes
I hope someone else finds this helpful.
Run these three commands to make sure that you have all the relevant packages installed:
pip install bs4
pip install html5lib
pip install lxml
Then restart your Python IDE, if needed.
That should take care of anything related to this issue.
sudo apt-get install docker # DO NOT do this
is a different library on ubuntu.
Use sudo apt-get install docker-ce
to install the correct docker.
I too found Python lacking when it comes to reading and writing binary files, so I wrote a small module (for Python 3.6+).
With binaryfile you'd do something like this (I'm guessing, since I don't know Fortran):
import binaryfile
def particle_file(f):
f.array('group_ids') # Declare group_ids to be an array (so we can use it in a loop)
f.skip(4) # Bytes 1-4
num_particles = f.count('num_particles', 'group_ids', 4) # Bytes 5-8
f.int('num_groups', 4) # Bytes 9-12
f.skip(8) # Bytes 13-20
for i in range(num_particles):
f.struct('group_ids', '>f') # 4 bytes x num_particles
f.skip(4)
with open('myfile.bin', 'rb') as fh:
result = binaryfile.read(fh, particle_file)
print(result)
Which produces an output like this:
{
'group_ids': [(1.0,), (0.0,), (2.0,), (0.0,), (1.0,)],
'__skipped': [b'\x00\x00\x00\x08', b'\x00\x00\x00\x08\x00\x00\x00\x14', b'\x00\x00\x00\x14'],
'num_particles': 5,
'num_groups': 3
}
I used skip() to skip the additional data Fortran adds, but you may want to add a utility to handle Fortran records properly instead. If you do, a pull request would be welcome.
I have come across exactly the same problem when trying to write a client for the National Rail SOAP service with Perl.
The problem was caused because the Perl module that I'm using 'SOAP::Lite' inserts a '#' in the SOAPAction header ...
SOAPAction: "http://thalesgroup.com/RTTI/2008-02-20/ldb/#GetDepartureBoard"
This is not interpreted correctly by .NET servers. I found this out from Example 3-19 in O'Reilly's Programming Web Services with SOAP . The solution was given below in section 3-20, namely you need to explicitly specify the format of the header with the 'on_action' method.
print SOAP::Lite
-> uri('urn:Example1')
-> on_action(sub{sprintf '%s/%s', @_ })
-> proxy('http://localhost:8080/helloworld/example1.asmx')
-> sayHello($name)
-> result . "\n\n";
My guess is that soapclient.com is using SOAP::Lite behind the scenes and so are hitting the same problem when talking to National Rail.
The solution is to write your own client so that you have control over the format of the SOAPAction header ... but you've probably done that already.

The closest equivalent to Java's toString
is to implement __str__
for your class. Put this in your class definition:
def __str__(self):
return "foo"
You may also want to implement __repr__
to aid in debugging.
See here for more information:
Caution! This command can cause losing commit history, if user put the wrong commit mistakenly. Always have en extra backup of your git some where else just in case if you do mistakes, than you are a bit safer. :)
I have had a similar issue and wanted to revert back to an earlier commit. In my case I was not interested to keep the newer commit, hence I used Hard
.
This is how I did it:
git reset --hard CommitId && git clean -f
This will revert on the local repository, and here after using git push -f
will update the remote repository.
git push -f
Missed property runat="server"
or in code use Request.Params["TextArea1"]
Right now (as of 2008), all the SOAP libraries available for Python suck. I recommend avoiding SOAP if possible. The last time we where forced to use a SOAP web service from Python, we wrote a wrapper in C# that handled the SOAP on one side and spoke COM out the other.
ImageButton
can't have text
(or, at least, android:text
isn't listed in its attributes).
The Trick is:
It looks like you need to use Button
(and look at drawableTop
or setCompoundDrawablesWithIntrinsicBounds(int,int,int,int))
.
If it wasn't checked in as a Java Project, you can add the java nature as shown here.
As mentioned in the earlier comment, stacked bar chart does the trick, though the data needs to be setup differently.(See image below)
Duration column = End - Start
The simplest way on Linux is, in my humble opinion,
sed -i 's/\r$//g' <filename>
The strong quotes around the substitution operator 's/\r//'
are essential. Without them the shell will interpret \r
as an escape+r and reduce it to a plain r
, and remove all lower case r
. That's why the answer given above in 2009 by Rob doesn't work.
And adding the /g
modifier ensures that even multiple \r
will be removed, and not only the first one.
A more modern version would be to use something akin to the following...
require 'rubygems'
puts Gem::Specification.all().map{|g| [g.name, g.version.to_s].join('-') }
NOTE: very similar the first part of an answer by Evgeny... but due to page formatting, it's easy to miss.
Put this line into your vimrc
:
set nobk nowb noswf noudf
"
nobackup
nowritebackup
noswapfile
noundofile
In windows that would be the:
C:\Program Files (x86)\vim\_vimrc
file for system-wide vim configuration for all users.
Setting the last one noundofile
is important in Windows to prevent the creation of *~
tilda files after editing.
I wish Vim had that line included by default. Nobody likes ugly directories.
Let the user choose if and how she wants to enable advanced backup/undo file features first.
This is the most annoying part of Vim.
The next step might be setting up:
set noeb vb t_vb=

errorbells
visualbell
to disable beeping in vim as well :-)
Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)
import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1
u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0
#option 1
#keep index of t
u.index = t.index
#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)
#now concat will keep number of rows
r=pd.concat([t,u], axis=1)

The following code is used by Google Now App and will NOT work for any other application.
I'm writing this post because it makes me angry, that WhatsApp does not allow any other developers to send messages directly except for Google.
And I want other freelance-developers to know, that this kind of cooperation is going on, while Google keeps talking about "open for anybody" and WhatsApp says they don't want to provide any access to developers.
Recently WhatsApp has added an Intent specially for Google Now, which should look like following:
Intent intent = new Intent("com.google.android.voicesearch.SEND_MESSAGE_TO_CONTACTS");
intent.setPackage("com.whatsapp");
intent.setComponent(new ComponentName("com.whatsapp", "com.whatsapp.VoiceMessagingActivity"));
intent.putExtra("com.google.android.voicesearch.extra.RECIPIENT_CONTACT_CHAT_ID", number);
intent.putExtra("android.intent.extra.TEXT", text);
intent.putExtra("search_action_token", ?????);
I could also find out that "search_action_token" is a PendingIntent that contains an IBinder-Object, which is sent back to Google App and checked, if it was created by Google Now.
Otherwise WhatsApp will not accept the message.

I have just discovered and used FETCH_HEAD
. I wanted a local copy of some software from a server and I did
git fetch gitserver release_1
gitserver
is the name of my machine that stores git repositories.
release_1
is a tag for a version of the software. To my surprise, release_1
was then nowhere to be found on my local machine. I had to type
git tag release_1 FETCH_HEAD
to complete the copy of the tagged chain of commits (release_1) from the remote repository to the local one. Fetch had found the remote tag, copied the commit to my local machine, had not created a local tag, but had set FETCH_HEAD
to the value of the commit, so that I could find and use it. I then used FETCH_HEAD
to create a local tag which matched the tag on the remote. That is a practical illustration of what FETCH_HEAD
is and how it can be used, and might be useful to someone else wondering why git fetch doesn't do what you would naively expect.
In my opinion it is best avoided for that purpose and a better way to achieve what I was trying to do is
git fetch gitserver release_1:release_1
i.e. to fetch release_1 and call it release_1 locally. (It is source:dest, see https://git-scm.com/book/en/v2/Git-Internals-The-Refspec; just in case you'd like to give it a different name!)
You might want to use FETCH_HEAD
at times though:-
git fetch gitserver bugfix1234
git cherry-pick FETCH_HEAD
might be a nice way of using bug fix number 1234 from your Git server, and leaving Git's garbage collection to dispose of the copy from the server once the fix has been cherry-picked onto your current branch. (I am assuming that there is a nice clean tagged commit containing the whole of the bug fix on the server!)
To add on to what Egon said, simply create your blob called "folder/1.txt", and it will work. No need to create a directory.
I had the same problem. Here is how I resolved the issue with help from the Microsoft link: https://msdn.microsoft.com/en-us/library/office/gg278655.aspx

If you want to see the array as an array, you can say
alert(JSON.stringify(aCustomers));
instead of all those document.write
s.
However, if you want to display them cleanly, one per line, in your popup, do this:
alert(aCustomers.join("\n"));
As a pure CSS solution for the close or 'times' symbol you can use the ISO code with the content property. I often use this for :after or :before pseudo selectors.
The content code is \00d7.
Example
div:after{
display: inline-block;
content: "\00d7"; /* This will render the 'X' */
}
You can then style and position the pseudo selector in any way you want. Hope this helps someone :).
The maximum length of a string variable is only 2GiB - (2^(32-1) bits). Variables can be addressed on a character (8 bits/1 byte) basis and the addressing is done by signed integers which is why the limit is what it is. Arrays can contain multiple variables that each follow the previous restriction but can have a total cumulative size up to memory_limit of which a string variable is also subject to.
Try AddDate:
package main
import (
"fmt"
"time"
)
func main() {
now := time.Now()
fmt.Println("now:", now)
then := now.AddDate(0, -1, 0)
fmt.Println("then:", then)
}
Produces:
now: 2009-11-10 23:00:00 +0000 UTC
then: 2009-10-10 23:00:00 +0000 UTC

behaviors:AutoCompleteBehavior.AutoCompleteItemsSource="{Binding TestItems}" />
IMHO this is much easier to get started and manage than the other options listed above.
I usually use sys.platform
(docs) to get the platform. sys.platform
will distinguish between linux, other unixes, and OS X, while os.name
is "posix
" for all of them.
For much more detailed information, use the platform module. This has cross-platform functions that will give you information on the machine architecture, OS and OS version, version of Python, etc. Also it has os-specific functions to get things like the particular linux distribution.
You can try this simple android dialog popup library to cut the cluttered dialog code. It is very simple to use on your activity. after that you can have this code in your activity to show dialog
Pop.on(this).with().title(R.string.title).layout(R.layout.custom_pop).show();
where R.layout.custom_pop is your custom layout the way you want to decorate your dialog.
write code in body tag like this
<body style="background-image: url('Image URL');" >
</body>
Using Chrome, searching for the images files in links (as proposed previously) didn't work as it is generating something like:
(...) i18nTemplate.process(document, loadTimeData);
</script>
<script>start("current directory...")</script>
<script>addRow("..","..",1,"170 B","10/2/15, 8:32:45 PM");</script>
<script>addRow("fotos-interessantes-11.jpg","fotos-interessantes-> 11.jpg",false,"","");</script>
Maybe the most reliable way is to do something like this:
var folder = "img/";_x000D_
_x000D_
$.ajax({_x000D_
url : folder,_x000D_
success: function (data) {_x000D_
var patt1 = /"([^"]*\.(jpe?g|png|gif))"/gi; // extract "*.jpeg" or "*.jpg" or "*.png" or "*.gif"_x000D_
var result = data.match(patt1);_x000D_
result = result.map(function(el) { return el.replace(/"/g, ""); }); // remove double quotes (") surrounding filename+extension // TODO: do this at regex!_x000D_
_x000D_
var uniqueNames = []; // this array will help to remove duplicate images_x000D_
$.each(result, function(i, el){_x000D_
var el_url_encoded = encodeURIComponent(el); // avoid images with same name but converted to URL encoded_x000D_
console.log("under analysis: " + el);_x000D_
if($.inArray(el, uniqueNames) === -1 && $.inArray(el_url_encoded, uniqueNames) === -1){_x000D_
console.log("adding " + el_url_encoded);_x000D_
uniqueNames.push(el_url_encoded);_x000D_
$("#slider").append( "<img src='" + el_url_encoded +"' alt=''>" ); // finaly add to HTML_x000D_
} else{ console.log(el_url_encoded + " already in!"); }_x000D_
});_x000D_
},_x000D_
error: function(xhr, textStatus, err) {_x000D_
alert('Error: here we go...');_x000D_
alert(textStatus);_x000D_
alert(err);_x000D_
alert("readyState: "+xhr.readyState+"\n xhrStatus: "+xhr.status);_x000D_
