Table alias scope in informix SQL
In the following example SQL
select * from (
select col
from myTable mt
inner join anotherMyTable amt on mt.id = amt.id
) as t
where
exists (select amt.colX from anotherMyTable amt where amt.id = 42)
The 'amt' alias is defined in two places. Is it correct to declare the
second table alias with the same name as the first or I should use another
name (amt2) ?
In this example I assume that both aliases are located in different scopes
so it's okay to use the same name. I use Informix DBMS.
p.s. it's an example SQL, the question is only about table alias scope.

Mysql subquery sum of votes
Mysql subquery sum of votes
I've got a table of votes, alongside a table of 'ideas' (entries)
Basically, I want to retrieve an object that can be read as:
id,
name,
title,
votes : {
up : x,
down : y
}
So it's simple enough until I get to the subquery and need to do two sets
of SUMs on the positive and negative values of votes.
SELECT id,name,title FROM ideas
LEFT JOIN votes ON ideas.id = votes.idea_id
My (simplified) votes table looks something like:
id
idea_id
value
Where value can be either a positive or negative int.
How would I go about getting the above object in a single query?
Bonus point: How would I also get an aggregate field, where positive and
negative votes are added together?

Intersecting two dictionaries in Python
Intersecting two dictionaries in Python
I am working on a search program over an inverted index. The index itself
is a dictionary whose keys are terms and whose values are themselves
dictionaries of short documents, with ID numbers as keys and their text
content as values.
To perform an 'AND' search for two terms, I thus need to intersect their
postings lists (dictionaries). What is a clear (not necessarily overly
clever) way to do this in Python? I started out by trying it the long way
with iter:
p1 = index[term1]
p2 = index[term2]
i1 = iter(p1)
i2 = iter(p2)
while ... # not sure of the 'iter != end 'syntax in this case

Backbone: Scroll event not firing after back button is pressed
Backbone: Scroll event not firing after back button is pressed
I'm using the following function to change the primary view of my Backbone
application:
changeView: function(view, options) {
if (this.contentView) {
this.contentView.undelegateEvents();
this.contentView.stopListening();
this.contentView = null;
}
this.contentView = view;
if (!options || (options && !options.noScroll)) {
$(document).scrollTop(0);
}
this.contentView.render();
},
As you can see, I'm resetting the scroll position every time the primary
view changes (so that the user doesn't land on the middle of a view after
scrolling down on the previous view). However, when the user presses the
back button, the scroll event isn't firing at all if you try to scroll
down. If you try to scroll up, however, then the scroll positions seems to
get reset to a position further down the page, after which scrolling works
normally.
Any ideas on what the cause might be?

I am using Spring MVC + Hibernate.
@Serice

return getGenVal;
}
}
@Controller
@Resource(name = "PersistenceTemplate")
private PersistenceTemplate pt;
pt.save(entityFoo);
My Project is running well. But is it compulsory to make @repository Class
and Interface for implementation like following, which is alternative to
above
Interface
public interface IOperations{

@repository
@Repository

Now I think interface is no matter for spring mvc because it manage proxy
by default if no found!
which implementation will u prefer either with @repository and interface
or without @repository and interface.

query/shred large xml document into sql server
query/shred large xml document into sql server
I'm looking to query an xml file that's in excess of 80GB (and insert the
results into a pre-existing db). This prevents me from simply declaring it
as an xml variable and using openrowset. I am NOT looking to use a CLR and
would prefer an entirely TSQL approach if possible (looking to do this on
SQL Server 2012/Windows Server 2008)
With the 2Gb limit on the XML datatype, I realize the obvious approach is
to split the file into say 1GB pieces. However, it would simply be too
messy to be worthwhile (Elements in the document are of varying sizes and
not all elements have the same sub-elements. Only looking to keep some
common elements though).
Anyone have a suggestion?

how to get list of user defined tables in the specific database in sybase
how to get list of user defined tables in the specific database in sybase
I need to list the name of all tables in the specific database in sybase
and then filter these table name according some string in the name.
this gives current database but i cant specify specific database
select name from sysobjects where type = 'U'
this gives more than tables, it includes trigger and stored procedure
Select name from sysobjects
WHERE db_name()='pad_orr_db'
does any body know how to do it and also filter the name of tables by some
string in the name for example only the table with the SASSA in the name
be displayed?
thanks in advanced

WCF service fails to call another WCF service on same machine
WCF service fails to call another WCF service on same machine
I have a website hosted in IIS7 in server A. The website calls a web
service that is also hosted in server A, but the call returns an error
401. I tried referencing to the web service by IP address, host
(A.domain.com), and fully qualified dsn. None worked.
After some research, I found out about the loopback check, and the
BackConnectionHostNames.
Refer to this article
Disabling the loopback check fixes the problem, but is not a desirable
solution.
For the BackConnectionHostNames, I tried adding:
A
A.domain.com
A.full.domain.com
But it didn't work.
I played some with IIS http bindings for the website, I tried adding
A.domain.com to the host name, and I also tried setting the IP, but still
got the same error.
Am I missing something? (I clearly am...) Where else should I be looking at?
Any help appreciated. Thanks

font-family not showing in IE8
font-family not showing in IE8
I'm just trying to add a regular font-family to my website, but IE8 won't
display it. It just displays its default Times New Roman. This is my CSS:
body {
font-family: Arial, Helvetica, sans-serif;
}
This appears fine on IE7, 9 and obviously Chrome and Firefox but I'm not
sure why IE8 is having issues?
My doctype is:
<!DOCTYPE HTML>
I'm really stuck on this. It's such a simple thing, I'm not sure why IE8
is not liking it. Any help would be very much appreciated.

Download to root directory
Download to root directory
Okay, so I have been searching for ages to find this but no luck.
I am using:
Me.downloader.DownloadFileAsync(New Uri(fileUrl),
Path.GetFileName(fileUrl), Stopwatch.StartNew)
To download a file but I want it to save to the root directory of my
program in a file called launcher.
So for example, if my program is on the desktop and I open it and click
start I want it to create the launcher folder if it's missing then
download the files into that and if it's not then just download the files
into it.
I've been looking everywhere to find code which would allow me to do this
and I have tried lots of different things.
At the moment, it justs saves in the root directory of where the program is.
Thanks.

Direct Oracle Access cuts off the end of unicode (wide) strings
Direct Oracle Access cuts off the end of unicode (wide) strings
I am encountering a problem with unicode (wide) string field in Delphi XE2
is not returning last part of string and any database control component
also is not showing whole string completely to the end.
You can see the simple test below.
with TOracleDataSet.Create(self) do
try
Session := OraSession;
SQL.Text := 'CREATE TABLE test1 (fsString10 VARCHAR2(10))');
ExecSQL;
SQL.Text := 'INSERT INTO test1 (fsString10) VALUES ('1234567890')');
ExecSQL;
SQL.Text := 'INSERT INTO test1 (fsString10) VALUES ('é234567890')');
ExecSQL;
SQL.Text := 'INSERT INTO test1 (fsString10) VALUES ('éöóêåíãøùç')');
ExecSQL;
SQL.Text := 'SELECT fsString10 FROM test1';
Open;
while not Eof do
ShowMessage(FieldByName('fsString10').AsString);
// '1234567890' turned into '1234567890'
// 'é234567890' turned into 'é23456789'
// 'éöóêåíãøùç' turned into 'éöóêå'
SQL.Text := 'DROP TABLE test1');
ExecSQL;
finally
Free;
end;
As you can see unicode strings is not properly loaded.
On the other hand the "Direct Oracle Access 4.1.3" component didn't save
chars in the string after half one on post record. Anyway it saves only
first half-string.
Is there a way to fix it?
BytesPerCharacter is set to bcAutoDetect.
I have tried toggling NoUnicodeSupport and all other options with no luck.
Does anyone have any ideas on how to fix this?

As you can see unicode strings is not properly loaded.
On the other hand the "Direct Oracle Access 4.1.3" component didn't save
chars in the string after half one on post record. Anyway it saves only
first half-string.
Is there a way to fix it?
BytesPerCharacter is set to bcAutoDetect.
I have tried toggling NoUnicodeSupport and all other options with no luck.
Does anyone have any ideas on how to fix this?
Parsing XML with Python ignoring parts
Parsing XML with Python ignoring parts
I'm having difficulty parsing a particular style of XML.
The XML file looks like:
<channels>
<genre type = blah1>
<channel name="Channel 1">
<show>
<title>hello</title>
</show>
</channel>
<channel name="Channel 2">
<show>
<title>hello</title>
</show>
</channel>
</genre>
<genre type="blah2">
<channel name="Channel 3">
<show>
<title>hello</title>
</show>
</channel>
</genre>
<channels>
So my problem is as follows:
channelList = rootElem.find(".//channel[@name]")
howManyChannels = len(channelList)
for x in range(1, howManyChannels):
print x
print rootElem.find(".//channel[@name]["+str(x)+"]").get('name')
for y in rootElem.find(".//channel[@name]["+str(x)+"]"):
print y.findtext('title')
This gets to Channel 2 and then errors with:
Traceback (most recent call last):
File "parse.py", line 17, in <module>
print rootElem.find(".//channel[@name]["+str(x)+"]").get('name')
AttributeError: 'NoneType' object has no attribute 'get'
Why doesn't the code:
for y in rootElem.find(".//channel[@name]["+str(x)+"]"):
include the 3rd channel, why is it being isolated as it is in another
genre tab? How do I change the code to accommodate for this?
Thanks

I'm working on a www page that is gonna communicate with outside server (I

I would like to test messages my page is gonna receive from outside

debugging mode using VS 2013 and set up a breakpoint somewhere, but I
don't know how to make my page visible on the internet. It is visible on

Connect and read data from third-party site
Connect and read data from third-party site
It's a little bit hard to explain it but I'll try. I want to make an app
that connects to a third-party website, that displays some data. I HAVE NO
access to that site and I have NO idea how this site works.
The only thing I know is that it requires a username and a password to
connect to the site and then it displays some data.
My question is how to "read" that data (and how to connect to that site),
if it's possible.
I'm just asking generally, some tip or tutorial will be great.
Thank you.

Android graphics user interaction ie. balloon popper
Android graphics user interaction ie. balloon popper
I'm more wondering how to go about implementing my very simple game.
For anyone who has played Angry Birds Star Wars, you know that on the
screen where you select the stage, you can tap on the piggies in the
background, and they will explode.
My daughter likes to tap on these piggies more than actually playing the
game... so I thought it'd be fun to write a simple app that displays
bouncing pigs on the screen for her to tap and explode. I know such apps
already exist, but I also wanted to expand my own programming experience.
So I think I have an idea on how to implement tapping on static graphical
elements. You could simply keep track of the xy coordinates of where the
picture is, and as long as the user taps somewhere in the vicinity, it'll
trigger the picture to be replaced by an explosion animation. Or something
like that.
But how about moving graphics? I've found tutorials that teach how to
write a bouncing ball thread on a canvas. For my idea, should each
bouncing ball (piggy) have it's own thread?
Or should I take it a step further, and try using OpenGL instead of just
the android Canvas function?
What would you guys suggest?

Error in git install from source on Ubuntu
I had git previously installed using ubuntu apt-get installed. Recently

However now whenever I open a new termial on Ubuntu, I get the following

How can I remove this error. I do not have /usr/lib/git_core folder, but

increment width from right to left
increment width from right to left
in html, i want to increment the width from right to left.
<div dir="rtl" id="progress">
<dt id='dt'></dt>
<dd id='dd'></dd>
</div>
the main goal is to make this progress bar moves from right to left when i
use Arabic language in my website (default direction of Arabic language is
from right to left)
i tried the attribute dir as i wrote , but it didn't fix the problem.
I have an idea, but it will change the html, but that's not the correct
thing to do, because my website supports English & Arabic, and i don't
want to change the html, i just want to change the style, or a javascript
code.

Dummy questions about setting up git on amazon cloud ec2
Dummy questions about setting up git on amazon cloud ec2
first of all, apologize for dummy questions that I might throw here. It
would be nice if you could point the directions where should I go from
here.
I'm totally new to version control(as well as git) and cloud system.
However, it came to the point that I have to develop php web based
application on AWS EC2 instance and make codes contributable for future
developers.
I did successfully create EC2 instance that run PHP/MySQL and map the
domain with Elastic IP. So the website is now publicly accessible via port
80.
I also installed git using $sudo yum install git and configed user.name
and user.email
I then, go to root folder of the website (e.g. public_html) and run 'git
init' which create the fold ".git" and I then add file using "git add ."
and commit "git commit -m 'initial upload'"
Is that the right way to go? Would it be ok to have the project folder
sitting on /public_html (where accessible from anyone).
If above is ok, then where should I go from here? I would like to have git
server running on EC2 that allow developers to connect from their local
machines (e.g. Eclipse) while being able to keep the backup and compare
the different between codes.
What detail do I suppose to give developers so that they can connect to
git server and working on project?
I quick direction or few keywords to do more research would help.

Passing Data from a View Controller to a First Detail Controller and then to a Second Detail Controller
Passing Data from a View Controller to a First Detail Controller and then
to a Second Detail Controller
Posting my first question here on stackoverflow! Hope my question is
clear, here it is...
I have a Navigation Controller embedded in a First View Controller that
has a table view. From the table view I have a segue that pushes to a
First Detail Controller. Everything works fine, the segue passes the data
to the First Detail Controller, however I would like to push again from a
button to a Second Detail Controller.
The layout in the storyboard looks like this Image of storyboard
I set-up a Second Detail Controller and pushed to that from a button on
the First Detail Controller. However I can not figure out how to pass the
data I have in an array along to the Second Detail Controller. I added an
NSLog line to see what was being passed along and the debug panel is
outputing "(null)"
Here is my viewdidload and segue code from the .m First View Controller
named ColorBookViewController:
- (void)viewDidLoad
{
[super viewDidLoad];
Color *color1 = [Color new];
color1.name = @"Red";
color1.hexnumber = @"FF0000";
color1.spanishname =@"Rojo";
Color *color2 = [Color new];
color2.name = @"Green";
color2.hexnumber = @"00FF00";
color2.spanishname =@"Verde";
Color *color3 = [Color new];
color3.name = @"Blue";
color3.hexnumber = @"0000FF";
color3.spanishname = @"Azul";
colors = [NSArray arrayWithObjects: color1,color2,color3, nil];

something more fundamental here? I tried setting up a second segue on the
First Detail Controller and the NSLog produces the correct result (the
color name in Spanish), but I am not sure how I would pass this onto the
Second Detail Controller:

to a Second Detail Controller
Posting my first question here on stackoverflow! Hope my question is
clear, here it is...
I have a Navigation Controller embedded in a First View Controller that
has a table view. From the table view I have a segue that pushes to a
First Detail Controller. Everything works fine, the segue passes the data
to the First Detail Controller, however I would like to push again from a
button to a Second Detail Controller.
The layout in the storyboard looks like this Image of storyboard
I set-up a Second Detail Controller and pushed to that from a button on
the First Detail Controller. However I can not figure out how to pass the
data I have in an array along to the Second Detail Controller. I added an
NSLog line to see what was being passed along and the debug panel is
outputing "(null)"
Here is my viewdidload and segue code from the .m First View Controller
named ColorBookViewController:
- (void)viewDidLoad
{
[super viewDidLoad];
Color *color1 = [Color new];
color1.name = @"Red";
color1.hexnumber = @"FF0000";
color1.spanishname =@"Rojo";
Color *color2 = [Color new];
color2.name = @"Green";
color2.hexnumber = @"00FF00";
color2.spanishname =@"Verde";
Color *color3 = [Color new];
color3.name = @"Blue";
color3.hexnumber = @"0000FF";
color3.spanishname = @"Azul";
colors = [NSArray arrayWithObjects: color1,color2,color3, nil];
}
-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
{
if ([segue.identifier isEqualToString:@"showColorDetail"]) {
NSIndexPath *indexPath = [self.tableView indexPathForSelectedRow];

Which processes do contribute to "commit charge"?
Which processes do contribute to "commit charge"?
I want to put the question squarely: what is the contribution of every
process into commited memory. Process Explorer refers to the total memory
committed and commit charge but only Private bytes, Working Set and
Virtual Memory is reported for the processes. I see no process that has
the commit column. Yet, I want to know who committed all my memory.

Shortcut to compile the .tex and .bib in one go with Texmaker?
As known, Texmaker requires the user to PDFLaTeX first, then BibTeX, and
then PDFLaTeX twice.
This is really tedious. Is there any shortcut that allows me to do it in
one go?

How to do 64 bit multiply on 16 bit machine?
How to do 64 bit multiply on 16 bit machine?
I have an embedded 16 bit CPU. On this machine ints are 16 bit wide and it
supports longs that are 32 bits wide. I need to do some multiplications
that will need to be stored in 64 bits. How can I do that with the given
constraints?

ListView performance is slow
ListView performance is slow
I have a custom ListView where I display some weapons which are retrieved
from a local database. I have a total of 88 rows, for each row a text and
an image is set each time getView() is called. The ListView lags while
scrolling fast and the garbage collector is going insane, deleting some 1M
objects per second. I'm not getting why.
Before I post my Adapter implementation, some explanation about how the
Image is set. My Weapon class is simply a data holder with setters and
getters. This is how names and images are getting set when the database
gets created (yeah it might seem very strange, but all other solutions
work even more slowly):
Weapon w = new Weapon();
w.setId(cursor.getLong(0));
w.setName(cursor.getString(1));
w.setImage(Constants.ALL_WEAPON_IMAGES[(int) cursor.getLong(0)-1]);
So I have an Array containing all weapon images in the form of
R.drawable.somegun. The data structure is implemented such way that ID-1
always points to the right drawable reference in my Array. The image field
in the Weapon class is an Integer. Now you have an idea how my getImage()
method works and below goes my Adapter:
public class Weapon_Adapter extends BaseAdapter {
private List<Weapon> items;
private LayoutInflater inflater = null;
private WeaponHolder weaponHolder;
private Weapon wp;
static class WeaponHolder {
public TextView text;
public ImageView image;
}
// Context and all weapons of specified class are passed here
public Weapon_Adapter(List<Weapon> items, Context c) {
this.items = (List<Weapon>) items;
inflater = LayoutInflater.from(c);
Log.d("Adapter:", "Adapter created");
}
@Override
public int getCount() {
return items.size();
}
@Override
public Weapon getItem(int position) {
return items.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
wp = (Weapon) getItem(position);
if (convertView == null) {
convertView = inflater.inflate(R.layout.category_row, null);
weaponHolder = new WeaponHolder();
weaponHolder.text = (TextView) convertView
.findViewById(R.id.tvCatText);
weaponHolder.image = (ImageView) convertView
.findViewById(R.id.imgCatImage);
convertView.setTag(weaponHolder);
}
weaponHolder = (WeaponHolder) convertView.getTag();
weaponHolder.text.setText(wp.getName());
weaponHolder.image.setImageResource(wp.getImage());
// weaponHolder.image.setImageResource(R.drawable.ak74m);
return convertView;
}}
Now the strange thing: using the outcommented line to statically set the
same image for all items removes all lags and GC in not even called once!
I'm not getting it.. wp.getImage() returns exactly the same thing, only
R.drawable.name is different for each weapon. But GC removes tons of
objects and the ListView lags while scrolling. Any ideas what I'm doing
wrong?
P.S. I've tried all possible ways of saving the Image to database, and all
possible ways to set it, including setImageBitmap(), setImageDrawable()..
the one I posted above is the fastest, though it also causes lag and many
GC calls

Class variables behave differently for list and int?
Class variables behave differently for list and int?
The class shared variables are shared with all the instances of the
classes as far as I know. But I am having trouble getting my head around
this.
class c():
a=[1]
b=1
def __init__(self):
pass
x=c()
x.a.append(1)
x.b+=1 #or x.b=2
print x.a #[1,1]
print x.b #2
y=c()
print y.a #[1,1] :As Expected
print y.b #1 :why not 2?
y.a resonates with the x.a but y.b doesn't.
hope someone can clarify.
EDIT: And how can the same functionality be created for ints.

Android: Save Mediarecorder-Stream as playable file
Android: Save Mediarecorder-Stream as playable file
I want to record videos with my android device (Nexus 10) and upload it
later to youtube.
So far I'am recording with the android MediaRecoder and stream it via
LocalSocket to save the data to multiple files. But the files are not
playable.
I read some articles that sine API-Level 18 it is possible to convert
files with MediaCodec and/or MediaMuxer. And i found this this code, but i
do not really understand how to handle it.
Has anybody an easy example which shows how to convert the raw data from
the LocalSocket to a playable file (i.e. mp4 files)?
My MediaRecoder looks like this:
recorder = new MediaRecorder();
recorder.setAudioSource(MediaRecorder.AudioSource.DEFAULT);
recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT);
CamcorderProfile camcorderProfile_HQ =
CamcorderProfile.get(CamcorderProfile.QUALITY_HIGH);
camcorderProfile_HQ.fileFormat = MediaRecorder.OutputFormat.MPEG_4;
camcorderProfile_HQ.videoCodec = MediaRecorder.VideoEncoder.MPEG_4_SP;
recorder.setProfile(camcorderProfile_HQ);
recorder.setPreviewDisplay(surfaceHolder.getSurface());
clientSocket = new LocalSocket();
clientSocket.connect(new LocalSocketAddress(SOCKET_ADDRESS));
recorder.setOutputFile(clientSocket.getFileDescriptor());
recorder.prepare();
recorder.start();
Thanks in advance.

Cant remotely access my VNC Server ..
Cant remotely access my VNC Server ..
Ive installed a TightVNC server .. and it accepts connections on port
12589 instead of 5900 with authentication .. On my Local LAN of class A
private address .. I can access my VNC server running machine with the
java viewer .. and remote desktop works fine locally!
But I cant connect on the same port number on my public IP address
assigned to my WiFi router .. I have a DSL connection .. and ive even
forwarded the port 12589 to my 10.x.x.x static IP in Netgear WGR614v10
(tried all 3 protocols: UDP/TCP/both(any))
Online open port checker programs too report the port is closed!
Even with Disabling antivirus and firewall , I couldn't remote desktop ..
Is there anything more can be done ..

But I cant connect on the same port number on my public IP address
assigned to my WiFi router .. I have a DSL connection .. and ive even
forwarded the port 12589 to my 10.x.x.x static IP in Netgear WGR614v10
(tried all 3 protocols: UDP/TCP/both(any))
Online open port checker programs too report the port is closed!
Even with Disabling antivirus and firewall , I couldn't remote desktop ..
Is there anything more can be done ..

Array out of bounds - Basic Java
Array out of bounds - Basic Java
I'm learning how to program in Java but I can't seem to get past an array
problem. See, I get an array out of bounds error when I run this program:
I know this is probably really easy to solve but I have no idea what's
going on.
Thanks!
public class AlturaPromedio {
float alturas[];
int cont;
float promedio;
InputStreamReader inputStream = new InputStreamReader(System.in);
BufferedReader buffRead = new BufferedReader(inputStream);
float cargarAlturas() throws IOException {
alturas = new float[4];
for (cont = 0; cont < alturas.length; cont++) {
System.out.println("Escriba el nombre de la primer altura:");
alturas[cont] = Float.parseFloat(buffRead.readLine());
}
return alturas[cont];
}
float calcularPromedio() {
promedio = (alturas[1] + alturas[2] + alturas[3] + alturas[4] +
alturas[0]) / 5;

Selecting enabled rows with ClientSelectColumn
Selecting enabled rows with ClientSelectColumn
I have a telerik GridClientSelectColumn along with AllowMultiRowSection
set to true for selecting all rows. So on the server side, some of the
rows are disabled, but when I go ahead click the button, it will select
all the rows regardless the button is being enabled/disabled.
So I figured I can loop through all the rows on client side using jquery
and see if they are disabled previously and if so I will mark them as
unchecked during OnRowSelected.
But I am not sure how to go about it, I have a RadGrid, a MasterTableView
and several GridBoundColumn.
Any tips would be helpful!

Application freeze after manual rotation in iOS 5
Application freeze after manual rotation in iOS 5
So i have a bug. It appears when i try to rotate my application after user
clicked unlock rotation button. For this feature i use next code
RotateHelperViewController *viewController =
[[RotateHelperViewController alloc] init];
viewController.neededOrientation = currentDeviceOrientation;
self.orientationFromLockedState = currentDeviceOrientation;
[UIView animateWithDuration:0.4 animations:^{
[self presentModalViewController:viewController animated:NO];
}
completion:^(BOOL finished) {
[viewController dismissModalViewControllerAnimated:NO];
[viewController release];
self.orientationFromLockedState = -1;
}];
this bug appears only on ios 5.x on iOS 6.x all works good. Also rotation
works fine if we rotate automaticaly.

Communicate with multiple clients & server with certificates
Communicate with multiple clients & server with certificates
I have a software that communicates with different clients and servers.
For each server/client you need a certificate to communicate with it. For
the communication with the server there is mainly .cer/.crt needed, for
the clients .jks & .p12.
Im looking for the best way to deal with this different certificates &
keystores (in java):
.cer /.crt
.jks
.p12
If possible I dont want to programm every communication different and
every time new when the certificate-type changes. Is there a way??
As I never worked before with certificates or keystores any help is
appreciated. Thanks!

Basic Object Structure and Calling for JavaScript
Basic Object Structure and Calling for JavaScript
I'm trying to do something very simple. That is, create an object with a
function I can call from somewhere else. I must be missing something. The
code I'm trying right now is:
function Object1() {
function Function1() {
alert("hello");
}
}
Object1.Function1();

Git hook for any action that updates the working directory
Git hook for any action that updates the working directory
Following an answer to a previous question, I implemented a Git hook
script which needs to fire whenever the working directory is updated. I
linked this script to the following in .git/hooks:
post-checkout
post-commit
post-merge
This mostly works, but not always. One case I found is git stash. This is
a problem because my hook generates a text file wihch I also mark with git
update-index --assume-unchanged to tell Git that I don't want to check in
changes (an empty version is checked in). However, git stash will revert
the assume-unchanged file (to the empty file), which means the hook needs
to run again, yet the hook is not invoked after git stash.
I suspect a similar problem may exist with git rebase too, but that's not
as easy to explain.
I want a hook which Git will always run after updating the working
directory. Is this possible?

Java Tapestry: Clearing a count value after a t:loop
Java Tapestry: Clearing a count value after a t:loop
I am printing the first 12 elements of a Comments array. After 12 have
been printed, a "More" link is printed. I am doing using a COMMENT_COUNT
int, and iterating it on each comment printed. I want to return the value
of COMMENT_COUNT to 0 after the "More" link is printed. How can I do this?
I have left my current hack in place, in which I just call ${clearCount()}
after printing the "More" link (right now it spits "true" out into the
template). I am guessing there is a much, much better way to do this. I am
looking for a better way to call ${clearCount()}, or a better way to set
COMMENT_COUNT to 0 after printing the "More" link.

Android FTP file Upload
Android FTP file Upload
I want to upload a existing file from my Android to a FTP-Server.
The following code works, but only in its own project.
public class FtpConnectDemo {
public static void main(String[] args) {
uploadDatei(SERVER, "SERVER/htdocs/wa/data/ArtikelDatenbank.csv",
"ArtikelDatenbank.csv", USER, PASSWORD);
}
public static void uploadDatei(String ftpServer, String
pfadUndDateiName, String dateiName, String benutzer, String passwort)
{
StringBuffer sb = new StringBuffer("ftp://");
sb.append(benutzer);
sb.append(':');
sb.append(passwort);
sb.append('@');
sb.append(ftpServer);
sb.append('/');
sb.append(pfadUndDateiName);
sb.append(";type=a");
BufferedInputStream bis = null;
BufferedOutputStream bos = null;
try {
URL url = new URL(sb.toString());
URLConnection urlc = url.openConnection();
bos = new BufferedOutputStream(urlc.getOutputStream());
bis = new BufferedInputStream(new FileInputStream(dateiName));
int i;
// read byte by byte until end of stream
while ((i = bis.read()) != -1) {
bos.write(i);
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} finally {
if (bis != null) {
try {
bis.close();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
if (bos != null) {
try {
bos.close();
} catch (IOException ioe) {
ioe.printStackTrace();
}
}
}
}
}
If I include this code into my other project it doesn't work anymore. The
method is called by a click on a button. The onClickListener should call
the second method uploadCsvAufServer()
Here is my other project.
Calling method:
private void initObjekte() {
dbHelper = new DBController(this);
this.buttonSync = (Button) this.findViewById(R.id.button_sync);
this.buttonSync.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// 1. Erstellen einer csv-Datei, die die Werte aus 1.

);
// Bisher als "nein" gekennzeichnete Werte werden als

How to save a CSV file to a variable with a foreach loop?
How to save a CSV file to a variable with a foreach loop?
Basically, I am loading a CSV file via a HTML upload form, then saving it
into PHP. I need to create a foreach loop to somehow print out the file
line by line.
I am not to sure how to do this since I have honestly never designed a PHP
foreach loop before.
This is the code that is capturing and saving the multidimensional array
from the CSV file
$csv_array = array(array());
$file = fopen($_FILES['upload_csv']['tmp_name'], 'r');
if($file)
{
while (($line = fgetcsv($file)) !== FALSE)
{
$csv_array[] = array_combine(range(1, count($line)),
array_values($line));
}
fclose($file);
}
This is my current foreach loop which is not working well at all which I
grabbed and slightly changed from one of my other functions.
$all_questions;
if(!empty($csv_array))
{
foreach($csv_array as $question)
{
$all_questions = $all_questions . implode(',',$question) . "\n";
}
}
So in conclusion, I need my foreach loop to go through my multidimensional
array to save it as one big string. If my CSV file is like this:
question1,answer1,answer2,answer3,answer4
question2,answer1,answer2,answer3,answer4
question3,answer1,answer2,answer3,answer4
I need it saved into a variable in the exact same format. I need to also
keep my multidimensional array since I need it for other reasons.
Thanks in advance!

How to change DataGridView column value based on condition in C#
How to change DataGridView column value based on condition in C#
Is it possible to change the column value or cell value based on the
Condition.
Consider i am having 3 columns in a data-grid view (i.e) to find the
greatest of two number
The input from Data gird view is got from SQL Server
1.First Data grid view column is A and second one is B and 3rd column is
to find whether A is bigger than B or not. if the condition satisfies it
should display the text "TRUE" or else "FALSE" in 3rd Column

Comma gem export failing on Heroku - working on local environment
Comma gem export failing on Heroku - working on local environment
Using the the comma gem and exporting CSV files perfectly fine on my local
environment. Also working on our staging environment which is running on
an AWS instance.
ONLY failing on Heroku.
Heroku says:
2013-08-21T21:55:34.875724+00:00 app[web.1]: NoMethodError (undefined
method `klass' for nil:NilClass):
2013-08-21T21:55:34.875724+00:00 app[web.1]: app/models/job.rb:220:in
`block in <class:Job>'
2013-08-21T21:55:34.875724+00:00 app[web.1]:

2013-08-21T21:55:34.875724+00:00 app[web.1]:
app/controllers/jobs_controller.rb:18:in `index'
And line 220 in my Job model is:
Comma do
...
customer :first_name
...
end
job.rb includes the line:
belongs_to :customer
And customer.rb has:
has_many :jobs
And as I mentioned this entire thing works great on my local box - I click
the export button and out pops all the jobs, with each customer in the
appropriate column.
For whatever reason it's only failing on Heroku.
I'm using Ruby 2.0.0-p0 on Heroku, Comma gem only verified up to 1.9.2
according to the documentation - BUT - I'm using Ruby 2.0.0-p0 on the
staging server AND on my local environment and, again, it's working.
It's the 'klass" that's really throwing me off, because I don't have that
anywhere in my code. I've read other threads about the same error and
their solutions, but I don't have things like nested model forms and the
like.
It is some issue with Heroku & Ruby 2.0 and associations? I've got the
has_many and belongs_to on both sides, but still seems to be
misunderstanding the association...

Heroku says:
2013-08-21T21:55:34.875724+00:00 app[web.1]: NoMethodError (undefined
method `klass' for nil:NilClass):

2013-08-21T21:55:34.875724+00:00 app[web.1]:
app/controllers/jobs_controller.rb:18:in `index'
And line 220 in my Job model is:
Comma do
...
customer :first_name
...
end
job.rb includes the line:
belongs_to :customer
And customer.rb has:
has_many :jobs
And as I mentioned this entire thing works great on my local box - I click
the export button and out pops all the jobs, with each customer in the
appropriate column.
For whatever reason it's only failing on Heroku.
I'm using Ruby 2.0.0-p0 on Heroku, Comma gem only verified up to 1.9.2
according to the documentation - BUT - I'm using Ruby 2.0.0-p0 on the
staging server AND on my local environment and, again, it's working.
It's the 'klass" that's really throwing me off, because I don't have that
anywhere in my code. I've read other threads about the same error and
their solutions, but I don't have things like nested model forms and the
like.
It is some issue with Heroku & Ruby 2.0 and associations? I've got the
has_many and belongs_to on both sides, but still seems to be
misunderstanding the association...
AJax/PHP Login Form - Mysql Database [Jquery Mobile]
AJax/PHP Login Form - Mysql Database [Jquery Mobile]
I'm having an issue with AJAX/PHP form submission.
My ajax is as follows:
<script type="text/javascript">
$('#loginForm').submit(function() {
$.ajax({
type: "POST",
url: "php/server/login.php",
data: {
username: $("#username").val(),
password: $("#password").val()
},
success: function(html)
{
if(html == 'true')
{
window.location.replace('main.html');
}
else
{
$("#errorMessage").html(html);
}
},
beforeSend:function()
{
$("$errorMessage").html("Attempting to login...");
}
});
return false;
});
</script>
My form:
<form id="loginForm">
<div id="errorMessage"></div>
<div data-role="fieldcontain">
<label for="username">Username:</label>
<input class="required" id="username" type="text"
placeholder="Username" />
</div><!-- End Contained Fields -->
<div data-role="fieldcontain">
<label for="password">Password:</label>
<input class="required" id="password" type="password"
placeholder="Password" />
</div><!-- End Contained Fields -->
<div data-role="fieldcontain">
<input type="submit" id="login" value="Login" />
</div><!-- End Contained Fields -->
</form><!-- End Form -->
And then my login.php script:
<?php
session_start();
$username = $_POST['username'];
$password = md5($_POST['password']);
$db = new PDO('mysql:host=localhost;dbname=mobile;charset=utf8', 'root',
'password');
try {
$stmt = $db->query("SELECT * FROM users WHERE username='$username' and
password='$password'");
$row_count = $stmt->rowCount();
if($row_count == 1)
{
echo 'true';
$_SESSION['username'] = $username;
}
else
{
echo 'false';
}
} catch(PDOException $ex) {
echo "An error has occured!";
}
?>
I originally had programmed my whole JQuery Mobile application using just
raw php, but recently found out that I must use AJAX and Html to be able
to port it to IOS and Android using PhoneGap.
I'm rather new to using ajax and have read as many articles that I
could/topics here to try to get it to work. Unsure if I'm having a syntax
issue or just not handling it correctly.
My local machine is loading a mysql server (database name is mobile, table
I'm trying to load is users). I know that part is all correct because it
works fine with php.
Could someone explain my issue? Thank you.

Add the Empty space on view source using javascript or jquery
Add the Empty space on view source using javascript or jquery
Is there is a way to add the extra empty spaces while viewing source. I am
not asking for hiding the source. I want to add the extra white space in
the source code when you view.
http://www.immihelp.com/visitor-visa/sponsor-documents.html. If you visit
the site click view source then it appear with empty white space. Is there
is a way to do this in jquery or javascript.
Any suggestion would be great.
Thanks.

Delphi COM objects multithreading
Delphi COM objects multithreading
I've been programming for a while and regarding COM/ActiveX object, I'm
facing very strange issues, that are abviously above my knowledge. Here it
is. My software talks to COM objects using late binding. Since those COM
object talk to hardware (such as scientific camera for instance), I have
choosen to seralise all calls into a dedicated thread. this allows the
main thread to interact with the user. So I'm sending messages from the
main user thread (or any other thread) to the thread that is design to
dealing solely with activeX.
Here how it looks
procedure MythreadActiveX.execute;
begin
CoInitialize(nil);
Try
ComObject :=CreateOLEObject(COMID);
While not Terminated do
Begin
If PeekMessage(Msg,0,0,0,PM_REMOVE) then
Begin
TranslateMessage(Msg);
DispatchMessage (Msg);
end;
If (FEvent.WaitFor(TimOutMs)=wrSignaled) then // Wait for command
Begin
FEvent.ResetEvent;
Try
Case COM_Order of
Oder1:Begin
.........
end
Oder2:Begin
.........
end
end;
FEventComplete.SetEvent;
end;
end;
CoUnInitialize;
end;
This works like a charm with most COM server, but fails with other COM
DLL/Server, especially written in visual basic, where the I have noticed
with process explorer that the ActiveX code is executed into the main
thread despite what I did above ! The consequence result in - main thread
holding up - main thread memory corruption (with large array for
instance)... == my app crash
What is the cause ? is this related to ActiveX threading model ? I would
like to understand and to correct my code to cope with that (In that case,
the COM shall run in the main thread....)
Thanks (Since I spent time on this, i'm ready to provide more information
in order to understand)

Can I use .htaccess to convert a url slug to a POST request?
Can I use .htaccess to convert a url slug to a POST request?
I would like to use .htaccess to take a URL like this:
mydomain.com/some-url-slug
and instead redirects the user to mydomain.com, but with a POST request
that includes "some-url-slug".
Is this possible? Thanks!!

Horizontal scroll on UIScrollView without pan gesture
How can I make it so that when I use my UIScrollView the pan gesture
recognizer selector is not called.
I want to be able to scroll in the scroll view without the pan gesture
selector being called.
Here is my pan detected function:
- (void)panDetected:(UIPanGestureRecognizer *)panRecognizer
{
CGPoint translation = [panRecognizer translationInView:self.view];
CGPoint imageViewPosition = self.draggableImage.center;
imageViewPosition.x += translation.x;
imageViewPosition.y += translation.y;
self.draggableImage.center = imageViewPosition;
[panRecognizer setTranslation:CGPointZero inView:self.view];
}
I do not want it to be called when I am using my UIScrollView at the
bottom of the page.

Calculating limits. Am I correct? (with working)
Calculating limits. Am I correct? (with working)
This is my working for the first two questions (i and ii). Does anyone
know how to work out iii? Also, is my working correct? Any feedback is
appreciated. I also did a rough calculation of iii and I think the answer
is supposed to be 5 but I'm not too sure of the working.
(i) We are finding the limit as x approaches -2. According to the system
of equations, we should look at where it says -2 ¡Ü x ¡Ü 3 because x is
approaching -2 and -2 fits into this system. So Ix^2 - 4I if -2 ¡Ü x ¡Ü 3
is what we're looking at. What we're finding is the limit if x approaches
-2. So let's replace x with -2. Ix^2 - 4I I(-2)^2 - 4I I(4) - 4I I0I 0 lim
f(x) as x app. -2 = 0.
(ii) lim f(x) as x app. 2. This fits into Ix^2 - 4I if -2 ¡Ü x ¡Ü 3. Same
reasoning as above. After it says if, it says if -2 ¡Ü x ¡Ü 3 and if we
replace 2 for x here it makes sense. So now we replace 2 for x where it
says Ix^2 - 4I. Ix^2 - 4I I(2)^2 - 4I I(4) - 4I I0I 0 lim f(x) as x app. 2
= 0.

pyinstaller exe with pubsub
pyinstaller exe with pubsub
I have written a wxpython application that uses several different threads
all of which need to write to the log window (textctrl box). Because of
this I followed this tutorial
http://www.blog.pythonlibrary.org/2010/05/22/wxpython-and-threads/
And used wx.CallAfter and PubSub.
This was my original code
from wx.lib.pubsub import Publisher
Publisher().subscribe(self.messenger, "update")
wx.CallAfter(Publisher().sendMessage, "update", "Thread finished!")
def messenger(self, msg):
self.logtxtctrl.WriteText(msg.data)
this code worked brilliantly and thought it would be easy to use
pyinstaller to create an exe for my code.
How wrong was I!!
So after reading some comments it seems there are two versions of the
pubSub API, so using this
http://wiki.wxpython.org/WxLibPubSub
I tweaked my code to the following
from wx.lib.pubsub import setuparg1
from wx.lib.pubsub import pub
pub.subscribe(self.messenger, "update")
wx.CallAfter(pub.sendMessage, "update", data="Program success")
def messenger(self, data):
self.logtxtctrl.WriteText(data)
This code now works and again I tried to use pyinstaller and still no luck.
So i then read the following articles
How to get pubsub to work with pyinstaller?
http://www.pyinstaller.org/ticket/312
Both of which were very useful and I tried all the different variations of
changing the hook files and different spec files, I still cannot get it to
work.
These posts are almost 2 years ago and I would have thought adding pubsub
would be solved.
Can anyone please explain the process of what hooks I need, what to have
in a spec file and other elements I need to do to get it to work?
if there is no solution how else can I do thread safe communications to
widgets?
