'xmlrpclib.Fault: Request contains to few param' error when using ldtp
I've been trying to use the Windows implementation of LDTP (Cobra) for
testing a stand-alone application within Python. It seems to work fine at
first, albeit running slow most of the time. For example I was able to
select menu items:
selectmenuitem('Sample App','File;New')
However, when I tried to execute any of the following lines:
waittillguiexist('Sample App', 'btnOK')
rightclick('Sample App','tblcBRANCH')
I get the following error in Python:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "build\bdist.win-amd64\egg\ldtp\client.py", line 69, in __call__
File "C:\Python27\lib\xmlrpclib.py", line 1578, in __request
verbose=self.__verbose
File "build\bdist.win-amd64\egg\ldtp\client.py", line 186, in request
xmlrpclib.Fault: <Fault 0: 'Request contains too few param elements based on
method signature.'>
I assume that I may still encounter this error with other functions. Are
there any problems with my installation of LDTP? Any help is very much
appreciated.

Extern variable has different values in different C files
Extern variable has different values in different C files
I'm trying to use a shared variable in multi C files. So, I write a
program to use its value:
In the path: sonnh\epan\dissectors\socket_sonnh.h , I defined a extern
variable: extern int ServerSocket;
In the path: sonnh\tshark.c , after #include
<epan/dissectors/socket_sonnh.h> I create the init value ServerSocket =
socket(AF_INET,SOCK_STREAM,IPPROTO_IP);
In the path: sonnh\epan\dissectors\packet-camel.c, after #include
"socket_sonnh.h" I want to use the value of ServerSocket by command i =
send(ServerSocket, cSendBuff, 20, 0);
The flow of code is: after creation of ServerSocket in tshark.c --> (call
func in other file) --> (somewhere I don't know) --> call func in
packet-camel.c to send socket. I know this because i check the log.
But actually, I check the value of ServerSocket at the top and bottom of
tshark.c, it is always 336, but the value of this in packet-camel.c is
always 0. i think it is extern variable , so it keeps its value while
running in different files but in this case, i cannot see the value of
ServerSocket being the same with the value of 336 as seen in tshark.c.
Could you please help me to find out why and how can I solve this problem
to have the value of ServerSocket in packket-camel.c (using shared
variable). Thank you so much.

For a 2nd order linear ODE,find the interval where some non-trivial solutions remain bounded and some become unbounded
For a 2nd order linear ODE,find the interval where some non-trivial
solutions remain bounded and some become unbounded
$$y^{''}+(2\alpha-3)y^{'}+\alpha(\alpha-3)y = 0$$
Determine all values of $\alpha$, if any, for which some non-trivial
solutions remain bounded and some become unbounded as $t \rightarrow
\infty$.
The general solution I got is
$$y(t) = C_1e^{(3-\alpha)t}+C_2e^{-at}$$
And I think the interval is $(-\infty,3]$, but this is not the correct
answer. Can anyone help me?

How to reload view asynchronously when carrierwave_backgrounder processing completes?
How to reload view asynchronously when carrierwave_backgrounder processing
completes?
I am using the carrierwave_backgrounder gem in a Rails 3.2 app to handle
background processing of image files and transfer to S3 via queue_classic.
The gem sets a file_processing boolean to null when processing is
complete, enabling the following:
#partial
<% if file.file_processing.nil? %>
<%= image_tag file %>
<% else %>
<p>processing</p>
<% end %>
I am using jquery to handle multiple file uploads (jquery-fileupload).
When a file upload completes, it triggers an ajax response via create.js
to render the partial.
This is fine, but means I end up with a long list of 'processing'.
Is there a callback I can take advantage of to reload the partial when
background processing is complete?

Resharper ToString Format Completion
Resharper ToString Format Completion
In the Reshaper 8.1 the new ToString() Format Completion is great, but for
DateTime all the options seem to be in America culture, eg month/ day
/year, being in Australia this is not very useful is there any way you can
chnage the default completion options so that day/month/year and
day-month-year could be added or replace the current list of formats,
If not how can I turn off only the datetime toString code completion ?

How to add jquery to jasmine/angularjs unittests
How to add jquery to jasmine/angularjs unittests
I have a project which is builded on plain angular.js code. We creates
unittest with jasmine. But now we need to grab some 3rd party components
(some directives from Angular-Bootstrap), which is also pure angular.js
inside, but for testing that components some jQuery code and methods calls
used. And now a lot of 3rd party tests failed with exception like [object]
had no method 'trigger' and stuff like that
So my question is how to include jquery to my tests, to make 3rd party
unitests valid. I run tests with Karma.

Understanding php class structure from a javascript OOP background (how to adapt code workflow)
Understanding php class structure from a javascript OOP background (how to
adapt code workflow)
I have been attempting to write a simple RESTful api in php. Part of my
goal in doing this is to get a good grasp on how to approach php OOP
projects. In javascript, I have no issue with encapsulation, inheritance,
etc. I generally start out with a single object (maybe even just as a
namespace) that I will nest everything in, i.e.var appName = {}. A simpler
object may just be a group of methods...then are a few typical needs like
an init function to set things up and/or execute/run function in which I
can detail a flow. I like to use a few general functions there that
summarize everything that will happen, then detail them, then detail
those, etc, so it is always easy to see how the result is produced, and
you can investigate the details further as needed. I also keep everything
independent so that each function doesn't have to worry about how it gets
its dependencies, etc. So, I hope that gives you an idea of where I'm
coming from.. I am utterly lost in the world of oop php.
I went ahead and wrote a simple api in js just to demonstrate what I'm
trying to do. It could be better, but this is just a quick example.
http://jsbin.com/AmIfApO/3/edit I'll include that code at the end of my
post. I have attempted for weeks to achieve this functionality in php, and
have failed, failed, failed. I can make it work, but it's just awful code
and I am determined to write it using best practices. For the sake of not
appearing lazy, here's the latest php rewrite I tried....ended in disaster
like always http://pastebin.com/cKw9YeVz.
With js, I eventually saw the right example/ got the right advice and the
idea became pretty clear. I think that seeing even just the basic design
flow of how this would be done in php would probably help me tie in
everything I've learned. Something just hasn't clicked. If you can give me
an example of what classes I should have here or how to divide things up,
I would be so appreciative.

http://jsbin.com/AmIfApO/3/edit I'll include that code at the end of my
post. I have attempted for weeks to achieve this functionality in php, and
have failed, failed, failed. I can make it work, but it's just awful code
and I am determined to write it using best practices. For the sake of not
appearing lazy, here's the latest php rewrite I tried....ended in disaster
like always http://pastebin.com/cKw9YeVz.
With js, I eventually saw the right example/ got the right advice and the
idea became pretty clear. I think that seeing even just the basic design
flow of how this would be done in php would probably help me tie in
everything I've learned. Something just hasn't clicked. If you can give me
an example of what classes I should have here or how to divide things up,
I would be so appreciative.

Different increment on a for loop depending on a boolean
Different increment on a for loop depending on a boolean
How can i select the increment on a for loop depending on a boolean,i am
trying to do something like this:
for (int y = iniY; isdown? (y >= endY): (y <= iniY+dy) ; isdown?
--y:y++);
the for loop accepts the termination but not the increment...
The working code i currently have is something like this:
if(isdown)
for (int y = iniY; y >= endY; --y) {
code lines...
}
else
for (int y = iniY; y <= iniY+dy; ++y) {
code lines...
}
the code can not be extracted to a new method because it works on many
variables...

Adding to url with link
Adding to url with link
My url contains many variables that I want untouched (don't worry they
aren't important).
Let's say it contained...
../index.php?id=5
How would I make a url that just adds
¤t=1
rather than replacing it entirely?
I'd like...
../index.php?id=5¤t=1
rather than..
../index.php?current=1
I know it's a simple question but that's why I can't figure it out.
Thanks.

setInterval crashes my browser when running a user script?
setInterval crashes my browser when running a user script?
Okay so the script works but setInterval keeps crashing my browser after
30secs or so. At least I think that's what's happening.
Here's the code:
var count = 0;
setInterval(function()
{
var ifLose = document.getElementById('result-text').innerHTML;
if (ifLose.length > 4)
{
count++;
document.getElementById("bet-multiplier").click();
document.getElementById("bet-bt").click();
}
else
{
for (count > 0; count--;)
{
document.getElementById("bet-divider").click();
}
document.getElementById("bet-bt").click();
}
}, 1000);
What am I doing wrong? Does it have something to do with count and the for
loop? Any help is greatly appreciated!

Why does it print -2 when i pass "y" as my query param and -5 when i pass

Spawning multiple threads that monitor different files in a servlet
Spawning multiple threads that monitor different files in a servlet
I am trying to spawn multiple threads that monitor different log files. So
basically user types in the host and path of log file to tail, then hits
the montior button which will then start a thread and initiate the
tailing. My problem is that I know threads are not supposed to be spawned
in a servlet as it would cause tomcat to complain about resources. The
other thing is I need to be able to stop tailing of the file whenever the
user decides to stop monitoring button. My first approach was to have a
map that takes in the thread and starts tailing of file, then whenever I
hit stop monitoring file then I get thread by key then call a method
stopThread which I flag a volatile attribute in and set it to false then
it stops. Is there a way which I can do it maybe using ExecutorService and
make the thread run without halting the program as I understand that
Callable will wait for results to return which in my case I don't want
halting. Any shed of ligh is highly appreciated. Thank you in advance.

Absolutely positioned element margins move other elements
Absolutely positioned element margins move other elements
I need to animate the margin of form inputs without affecting any other
element's positions. So I gave all the inputs position: absolute for all
of the inputs in the form.
However, this has created a problem for me: all of the inputs stick close
together and if add a margin-top: 40px to them it affects all of the
inputs as one element rather than spacing them out individualy.
How do I space out all the input elements individually?

Java Arrays: Find Two Points In A Three-Dimensional Space Nearest To Each Other
Java Arrays: Find Two Points In A Three-Dimensional Space Nearest To Each
Other
As the title suggests, I'm working on a homework assignment where we are
limited to using multi-dimensional arrays in order to create a program
that finds two points nearest to each other in a three dimensional space.
So far my code looks like this (hybridized from examples in my textbook
and my own code):
package exercise7_7;
public class Exercise7_7 {
public static void main(String[] args) {
java.util.Scanner input = new java.util.Scanner(System.in);
System.out.println("Enter the number of points:");
int numberOfPoints = input.nextInt();
double[][] points = new double[numberOfPoints][3];
System.out.println("Enter " + numberOfPoints + " points:");
for (int i = 0; i < points.length; i++) {
points[i][0] = input.nextDouble();
points[i][1] = input.nextDouble();
points[i][2] = input.nextDouble();
}
int p1 = 0, p2 = 1, p3 = 2;
double shortestDistance = distance(points[p1][0] , points[p1][1] ,
points[p1][2] ,
points[p2][0] , points[p2][1] , points[p2][2] ,
points[p3][0] , points[p3][1] , points[p3][2]);
for (int i = 0; i < points.length; i++) {
for (int j = i + 1; j < points.length; j++) {
double distance = distance(points[i][0] , [points[j][0] ,
points[j][1] , points[j][2]);
if (shortestDistance > distance) {
p1 = i;
p2 = j;
shortestDistance = distance;
}
}
}
System.out.println("The closest two points are " + "(" + points[p1][0]
+ "," + points[p1][1] +
and (" + points[p2][0] + "," );
}
public static double distance(
double x1, double y1, double z1, double x2, double y2, double z2) {
return Math.sqrt(((x2 - x1) * (x2 - x1)) + ((y2 - y1) * (y2 - y1)) +
((z2 - z1) * (z2 - z1)));
}
}
Thanks for the help guys. I'm running on 2 hours of sleep for 2 days now
so please excuse any stupid questions or sloppy code.

About Plack::Middleware::Session, Do we really need to store the sessions?
About Plack::Middleware::Session, Do we really need to store the sessions?
In the builder part of a psgi app, I use the following code which I
remember seeing somewhere.
enable 'Plack::Middleware::Session',
store => Plack::Session::Store::DBI->new(
get_dbh => #....
),
state => Plack::Session::State::Cookie->new(
session_key => 'id_session',
httponly => 1,
);
1) Why do people store the sessions? And store the sessions in the server
side? 2) What happens if no sessions are stored?
I have a psgi running, where I used 'Plack::Middleware::Session' without
knowing its real purpose and now my sessions table is approaching 500
megas, so I really want to erase this if there is no need.

NSDictionary - (for id foo in dict) vs (for NSString *foo in [dict allKeys])
NSDictionary - (for id foo in dict) vs (for NSString *foo in [dict allKeys])
Suppose there is an NSDictionary *dict. What is the difference between the
following?
for (id key in dict) {
NSLog(@"value: %@", dict[key]);
}
for (NSString *key in [dict allKeys]) {
NSLog(@"value: %@", dict[key]);
}
I didn't know that the first version existed, and when I saw it I thought
it would be a compile-time error.

Invalid route name: 'users/:columnname_index' - Can't rollback, change column name, nor display some pages
Invalid route name: 'users/:columnname_index' - Can't rollback, change
column name, nor display some pages
I created a migration to add a Urlname column to Users table. Then I added
an index to the migration. Here's the resulting migration:
class AddUrlnameToUsers < ActiveRecord::Migration
def change
add_column :users, :urlname, :string
add_index :users, :urlname, :unique => true
end
end
Then I used rake db:migrate.
schema.rb contains the 'urlname' column & says it has a unique index.
However, certain pages on my site have errors: Invalid route name:
'users/:urlname_index'.
Fine, I don't want to call it 'urlname' anyway. I want to call it
'permalink'. But now I can't generate a FixColumnName migration, a
RemoveUrlNameFromUsers, nor can I rollback - same "Invalid route name:
'users/:urlname_index'" error for all three.
So I removed add_index :users, :urlname, :unique => true from the
migration file, even though I had already migrated it. That didn't help.
My routes.rb contains
Crowdpublishtv::Application.routes.draw do
devise_for :users
resources :users
#resources 'users/:urlname', :to => 'User#booklist'
#match 'users/:urlname_index', :to => 'users#show'
devise_for :users
authenticated :user do
root :to => "users#booklist"
end
get "attachments/show"
resources :users do
resources :books
end
devise_for :users
resources :users do
member do
get 'booklist', 'blog', 'profileinfo', 'readerprofileinfo',
'orgprofileinfo'
end
end
end
I tried commenting out & uncommenting out the lines that are marked with
#. Didn't help.
Here's the relevant db:migrate status:

The *NO FILE* was something I thought I had rolled back... But since it
was long before 'Add urlname to users,' I'm pretty sure it's irrelevant.

This project contains code Java and Scala. The error occurred when I
translated into Scala a feature related to the splitting of the word
documents that was previously written in java. The error is in fact tied
to a jar file library org.apache.poi.
I tried to document but I have not found similar cases.
Any idea?
thanks

HDFS FileSplit locations
HDFS FileSplit locations
I have a cluster with an installation of hadoop-2.1.0-beta. Is there a way
to learn where each filesplit is located in my cluster? What I am looking
for is a list such as the following

edit: I know that such a list is available in Microsoft Azure.

how to read interleaved data with memmapfile()?
how to read interleaved data with memmapfile()?
I have a large (4GB+) data file I'd like to access. It contains samples i
of a number of different signals {a, b, c} as follows:
a_1 b_1 c_1 a_2 b_2 c_2 .... a_n b_n c_n
I would like to use memmapfile to retrieve, say, the a stream. Since I
know the number of signals and the number of samples, I tried:
m = memmapfile('data.dat','Format',{'int16',[nSignals
1],'sid'},'repeat',nSamples);
but this returns the useless m field
Data: nSamples x 1 struct array with fields:
sid
Of course the following works fine, but is very slow:
m = memmapfile('data.dat','Format','int16');
a = m.Data(1:nSignals:end);
How can I recover a without having to access the full data matrix?

XslCompiledTransform - Compile Error When Transforming XML Using XSLT
Stylesheet
I am trying to take a sheet in Excel and create an XML document using VBA
then transform that document using a XSLT stylesheet.
I have included the code below up to the point that I am having problems.
When I try to create an object like so:
Dim transformer As XslCompiledTransform ' transform document
I get this error:
Compile Error: User defined type - not defined
I was previously experiencing this error when defining
Dim objDom As DOMDocument
but referencing this question solved that problem for me. However, I
cannot find anything similar for this case.
Can someone explain to me if there is a reference that I need to include
and how to find these in the future?

password = 'myPswd'
url = 'https://NTLMwebsite/base.com'
nextPage = 'https://NTLMwebsite/base/next.com'
r = requests.get(url, auth=HttpNtlmAuth(username,password))

How do I request another page once I've passed NTLM? authentication. If I
simply do another request via: requests.get(nextPage,

Does anyone know how to follow a link ONCE you've bypassed NTLM?

Best ways of stopping sql injections? [duplicate]
Best ways of stopping sql injections? [duplicate]
This question already has an answer here:
How can I prevent SQL injection in PHP? 26 answers
Thanks to everyone for your help in advance. I am trying to learn mysql, I
was going to set up a database to practice with but I was on here reading
and looking for examples, and kept seeing people saying they where going
to get a sql injection. I have been reading about this for a while now,
and I'm getting more confused the more I read. I have decided to go with
PDO to prevent this. Even though from what I read it's the prepared
statements that makes it safe, and I will still have to whitelist it. My
question is if someone can give beginners like myself a set up we can use
that will be pretty effective at stopping these attacks. From what I
understand it seems almost imposable to stop them, I seen someone say
something about the dns is the only sure way. I would like to learn do
this the right way even though, I probably don't need to so much security
right now. If I'm not wrong they can still use blind injections even if
you use PDO, if so i was think of adding a delay of 2-5 seconds or
something like that. Idk if that would be to much on the user end, I'm
just learning, and have no real world experience. Also the type of things
I will be doing, will probably be very basic for now... mom a pop type
stuff. If I build someone a site with a user name and pass I don't want
them to get these attacks, I just don't like it. So if it is a little slow
but more secure I would like to be at least able to give them that option.
My thinking is to be really annoying to them and hopefully not be worth
it. From what I read also the length of the table names or user names can
make it harder for them, say using phrases instead of just 6-8 letters.
Also I think least privilege will help as well, but there seems there is
always a way around everything, and if your new and don't know exactly
what your doing, your going to vulnerable. I have copyied code from
somewhere that I was going to fit it for my needs, but I really have not
tried to put together what I'm looking for yet, still in the reading and
learning phase.
<?php
require_once "dBug!.php";
$dsn = "mysql:host=";
$user_name = "";
$pass_word = "";
$connect = new PDO($dsn, $user_name, $pass_word);
$sql = "SELECT * FROM books WHERE id <= 10";
$result = $connect->prepare($sql);
$status = $result->execute();
if (($status) && ($result->rowCount() > 0))
{
$results = array();

test("move 50", function () {
//Creates an element for testing and attaches to document
var el = appendToTest();
ok(el.css('left') == "auto", "element 0");
stop();
moveLeft(el, 50, 100);
setTimeout(function () {
equal(el.css("left"), "50px");
start();
}, 101);//Timeout duration
});
full fiddle
The test fails on all jQuery versions but 2.x (edge)
failed
Expected:
"50px"
Result:
"49.69220733642578px"
Diff:
"50px" "49.69220733642578px"
Incrementing the timeout duration enough makes the test pass so I figured
the animation didn't finish before being probed for the left property.
But this doesn't seem right. Having to guess how long to wait. Is there a
better way to do this?
Getting to know TDD i wrote a simple test suit for moving dom elements to
the left.
I testing animations I need to wait for them to finish. I didn't want to
use promises since it feels like monkey patching and I ended up using
qUnit example form:
test("move 50", function () {
//Creates an element for testing and attaches to document
var el = appendToTest();
ok(el.css('left') == "auto", "element 0");
stop();
moveLeft(el, 50, 100);
setTimeout(function () {
equal(el.css("left"), "50px");
start();
}, 101);//Timeout duration
});

std::make_pair with float array (float2, unsigned int)
std::make_pair with float array (float2, unsigned int)
I have a vector containing templated with a float2, unsigned int pair like:

float2 ab = {1.0, 2.0};
myVec.push_back(std::make_pair(ab, j));
This is how I expect it should work, though when I try to compile it I get

There are three questions i would like to ask.
1) Why does the animation for the value change not work? 2) Why does the
slider position move only when I release my finger from the button and
does not follow it? 3) Is using an NSTimer the best way to do it? I have
heard that NSTimer is a lot memory consuming...

OpenGL ES 2.0 Context in Android

I'm new to OpenGL on Android and I have read heavily documented samples,

Overriding a method that is called from a constructor
Overriding a method that is called from a constructor
If an instance of subclass is created, the output is sub0 sub2
Two questions on this:
Why is the subclass method called even though the superclass constructor
is not finished?
Why is the instance field not initialized when called from the superclass
constructor (the sub0 output)?
Example:
class superclass{
int i = 1;
void aMethod(){
System.out.println("super" + i);
}
superclass(){
aMethod();
}
}
class subclass extends superclass{
int i = 2;
void aMethod(){
System.out.println("sub" + i);
}
subclass(){
aMethod();
}
}

What to pair with Sinatra? Backbone, Ember, Angular, Knockout, or something else?
What to pair with Sinatra? Backbone, Ember, Angular, Knockout, or
something else?
I have a Sinatra REST service. I'm trying to put a "face" to it. Right
now, getting the information to and from the service and the database is a
bunch of JQuery AJAX calls like this:
$.getJSON()....
It's quite ugly. Given that I'm using Sinatra, which one of these
front-end frameworks would you recommend for me to learn? BTW, still
learning re: JavaScript, as I use JQuery with AJAX (though I accept that I
will probably need to learn native JS in the future), and have some
experience with MVC frameworks in PHP, but nothing yet on JavaScript.

Get parameter values of an ajax request after form submit
Get parameter values of an ajax request after form submit
I have a form_tag that looks like this:
<%= form_tag products_path, method:'get', remote: true, format: :js do %>
<%= number_field_tag :price, params[:price]%>
<%= submit_tag 'Go', class:'submit_button', :id => 'submit_button'%>
<% end %>
on the index action of the products_controller.rb, I have this:
def index
@price = params[:price]
....
end
The problem is that @price returns nil when i submit the form with remote:
true. I am able to get the value of @price when I remove remote: true and
submit the form without ajax. How can I get the parameters value(s) when i
submit the form via ajax ?

Visual C# 2010 Multiple lisbox choose
Visual C# 2010 Multiple lisbox choose
i have added 2 value in listbox as 1, it generates from MySQL code and
using While loop:
string name = myReader["name"].ToString();
string index = myReader["index"].ToString();
listBox1.Items.Add(index + " - " + name);
now im making a SELECT query with MySQL and i want to generate from
listbox, index which ill use in WHERE name = ..., i can use just string
name but when ppl have same name, it generates with errors so... example i
want to generate with index for no mistakes:
string query = "SELECT * FROM list WHERE index='" + listBox1.Text + "'";
but when it can`t choose only string index which added in top, it not
generates any name...
Finally my question is: how to force sql choose only index from listbox
when added 2 value as 1...
Thanks, hope i`ll get my answer

Equality operator issue (C++)
Equality operator issue (C++)
I'm getting the error
no match for 'operator==' in
'MyNestedClassPointer->MyClass::MyNestedClass::NestedVar == s'
Where s is a reference to a string, and NestedVar is a pointer to a
string. The offending line of code is an if statement comparing the two to
see if they're identical.
if(thePointer->theVar == s)
I have no overloaded operators, but I don't think I should have a need for
them, seeing as these are just string pointers we're dealing with. Now
correct me if I'm wrong, since I'm more than a little rusty, but can't I
do this?
I also apologize if my question is phrased 'incorrectly,' it's my first
post here.

Product searches over multiple sites
Product searches over multiple sites
So, I am not sure if there is any tools out there for this, but I have
been looking for quite some time, I want to be able to write a code that
would search a list of websites for a specific product. For example
searching for a model number and then bring back links to each page. It
would be fine if I were looking for one site alone, i would just use
Google or that site, but I want to search several sites at once. The key
is to reduce the time it takes to search all of these sites.

Best practice for repeated network tasks?
Best practice for repeated network tasks?
I have a small Android application in which I need to do some FTP stuff
every couple of seconds. After learning the hard way that running network
stuff on the UI thread is something Android does not really like, I've
come to this solution:
// This class gets declared inside my Activity
private class CheckFtpTask extends AsyncTask<Void, Void, Void> {
protected Void doInBackground(Void... dummy) {
Thread.currentThread().setName("CheckFtpTask");
// Here I'll do the FTP stuff
ftpStuff();
return null;
}
}
// Member variables inside my activity
private Handler checkFtpHandler;
private Runnable checkFtpRunnable;
// I set up the task later in some of my Activitiy's method:
checkFtpHandler = new Handler();
checkFtpRunnable = new Runnable() {
@Override
public void run() {
new CheckFtpTask().execute((Void[])null);
checkFtpHandler.postDelayed(checkFtpRunnable, 5000);
}
};
checkFtpRunnable.run();
Is this good practice to perform a recurring task that cannot run on the
UI thread directly? Furthermore, instead of creating a new AsyncTask
object all the time by calling
new CheckFtpTask().execute((Void[])null);
would it be an option to create the CheckFtpTask object once and then
reuse it? Or will that give me side effects?
Thanks in advance, Jens.

What is the equivalent of C++ '*&' in C ?. Does it even exist?
What is the equivalent of C++ '*&' in C ?. Does it even exist?
for example, how to implement this C++ code in C ?
void someFunction(type *&outParamOnly) ;
returnType someOtherFunction() ;
...
returnType someOtherFunction()
{
type *data = NULL ;
someFunction(data) ;
...
}
...
void someFunction(type *&outParamOnly)
{
bool condition ;
int array_len ;
...
if(condition) // variable's value passed to this function stays as it was
return ;
...
outParamOnly = new type[array_len] ; // value is moddified and it's
reflected in 'someOtherFunction'
...
}
...
I'm asking because I don't know how to create such equivalent. Does it's
complex ?. In fact I don't know much about C, but much more about C++
syntax, etc. I'm used to write in C++ and once I tryied C to feel
diffrence I'm not doing well when trying to implement what I want. I
expect positive answer - that it possible to create some equivalent, but
will it be running faster then in C++ or slower ? Please answer.

ZF2 how to display tweets in layout
ZF2 how to display tweets in layout
I'm developing a site using ZF2. One of the section in footer contains
tweets. I can fetch tweets but I am not sure how to display them in the
layout. I have following ideas but not sure which approach to use
Create a controller plugin and use it on each request.
Create a ViewHelper which fetches the tweets from the ServiceLocator and
call the helper in the layout
Attach an event to the MvcEvent::EVENT_RENDER in the module.php which sets
the html to a layout variable.
If there is anyother better approach, please let me know.

Javascript nested list css
Javascript nested list css
I have a list below:

<li>
<a>SubLink1</a>
</li>
...
</ul>
</li>
<li>
<a>Link2</a>

And would like to add 'css_class' to the current mouseovered <li> element:
document.getElements('li').addEvents({
mouseover: function(){
this.addClass('css_class');
},
mouseout: function(){
this.removeClass('css_class');
}
});
But this code is wrong as my parent<li> also has 'css_class'. How can I
fix this? Thanks.
