I'm using NSURLConnection as it appears in apple's examples to get xml files from a certain server - pretty straight forward. And most of time it works, but sometimes it's just stuck after initialing and don't get into connection's delegate methods. I'm working with WiFi & 3G and the same server all the time. When it comes to didFailWithError i see that mostly it was a timeout error. When I enter same link in Safari it takes a second to bring data. And after another trial I can access the link. What might be the reason for such a weird behavior? How can I improve it? What is the role of cache policy with NSURLConnection?
Thanks,

**There are three considerations to be thought of:**
1. Which version control software?
2. Which project mangement library?
3. Hosted or on my own server?
Version Control
-
Currently i am using **SVN**, and i planned to migrate to **GIT**. But there are also other possibilities like **Mercurial** or **Bazaar**. GIT and Mercurial seem to be very similar and i didn't understand the pro's and con's of both yet. Also, i'd like to know if there are also any other good alternatives.
Project Management
-
Currently, i use **Maven** to manage the Java library dependencies and to carry out the releases. There are also other tools like **Hudson** or **Apache Ivy** and many others. They should be able to handle library dependencies and be able to include currently released versions. Deployment automation is also a plus.
To host or not to host?
-
Currently i use an own server to host my SVN code and Maven releases. There are so many hosted solutions out there, and i think one of them would be nice to make it easier for people to join my project if they are interested.
Some of the platforms i heard about or used are for example **Github**, **Bitbucket**, **Google Code** or **Sourceforge**. They should be able to easily integrate support for the selected version control and project management software. Additional stuff for developers like a bugtracker and a wiki are good too and need to be considered useful.
The best team
-
So, which combination would you recommend? I'd like to gather all information and create an overview so that people can decide for themselves which setup meets their needs at best. | java | version-control | open-source | project-management | null | 12/07/2011 13:41:20 | off topic | A good team of version control, project management and hosting for an open-source Java project

My goal is to have an image of an Android, where the user can rotate
the arms and legs on touch. I've found that canvasses have a rotate method.
Also, I am using regions so that the user can better manipulate the image later. If this is a problem, let me know, but that's just my reasoning as I know someone will be confused by it.
Is there any other way to go about doing this? So far I have something like this (and it doesn't work):

There are about twenty tables with non-clustered, unique primary keys that were created during the MS Access > SQL Server upgrade.
Many of these tables also have unique, non-clustered indexes that are duplicates of the primary key.
I am attempting to clean this up.
But what I have found is after I recreate the primary keys as clustered indexes, and then try to rebuild the foreign key, the foreign key is referencing the old, duplicate index (which was unique).
I know this because it won't let me drop the duplicate indexes.
I would think SQL Server would always choose a primary key if one existed. Does SQL Server have a method of choosing between a unique index and a primary key? Or is this a bug?

The resulting file may also have another format (e.g. avi), but I would prefer mkv.
Btw. doesn't ffmpeg have an mkv muxer? My test with param *-f mkv* resulted in error *Requested output format 'mkv' is not a suitable output format* | 2 |

Customers will insert a chunk of code that we'll supply which includes a few <script> elements that build a widget in a <script>-created <iframe>. If they aren't already using the latest version of jQuery, this will also include (most likely) a <script> for Google's hosted version of jQuery.
The problem is that some customers may already have an older version of jQuery installed. While this may work if it's at least a fairly recent version, our code does rely on some recently introduced functionality in the jQuery library, so there are bound to be instances when a customer's jQuery version is just too old. We can't require that they upgrade to the latest version of jQuery.
Is there any way to load a newer version of jQuery to use only wihtin the context of our code, that will not interfere with, or affect, any code on the customer's page? Ideally, maybe we could check for the presence of jQuery, detect the version, and if it's too old, then somehow load the most recent version just to use for our code.
I had the idea of loading jQuery in an <iframe> in the customer's domain that also includes our <script>s, which seems like it might be feasible, but I'm hoping there's a more elegant way to do it (not to mention without the performance and complexity penalties of extra <iframe>s_).

I have MDI parent form - form1, form that starts and stops the timer - form 2, and a timerCalls class with all the timer logic.

{
InitializeComponent();
timerCalls.InitializeTimer();

Form2 code:

{
//send timer

Once I reopen the form2 all I can do is start and stop a new timer, but the previous one is still running. Everything works fine (timer starting and stopping) until I close form2. If the timer was on when I closed the form I can't stop it once I open the form2 again.

Basically what I am trying to do is read a list of events from a log file (with date and time info) and display in the jqGrid.
This is my setup:

System.out.println("doGet(): Received Request: " + aRequest.getServletPath());

// Calling getLogEntries() method populates logEntries & logEntriesCnt.
// logEntries contains the "rows" data as specified above.
// For now I am testing with 10 rows of data.
getLogEntries(aLocale);
JSONObject jqGridData = new JSONObject();
jqGridData.put("total", "1");
jqGridData.put("page", "1");
jqGridData.put("records", String.valueOf(logEntriesCnt-1));
jqGridData.put("rows", logEntries);
System.out.println("\n\n# Event Log Entries (" + new Date() + "):" + (logEntriesCnt-1));
System.out.println("jqGrid JSON: \n" + jqGridData.toJSONString());
aRequest.setAttribute("userdata", jqGridData.toJSONString());
aRequest.getRequestDispatcher("/jsp/eventlogtest.jsp").forward(aRequest, aResponse);
}
</code>
The output on the console (I validated it via http://jsonlint.com/):
<code>

As you can see from my Javascript. I have a test json data that corresponds to the json being sent from server. The Test data has no problem being rendered. Also I have tried changing jqGrid datatype. Again both work for test data:
datatype:'json'
datatype:'jsonstring'
I don't really mind about being able to page the data in the table. I just want to be able display the data and update it every 5 mins. I will do the updates once I get the basic data to display.
Any help appreciated.
Thanks in advance.

I output the userdata to the screen and again validated the json is correct. Firebug does not have any errors.
[3] My JavaScript:
<code>
$(document).ready(function(){
// Test Data: All entries double quoted
var userdatatest1 =
{
"total":"1",
"page":"1",
"records":"10",
"rows":[
{"id":"1","cell":["08\/12\/11","21:09:19","Communication Established"]},
{"id":"2","cell":["08\/12\/11","21:09:19","Monitoring Started"]},
{"id":"3","cell":["08\/12\/11","21:02:47","Communication Established"]},
{"id":"4","cell":["08\/12\/11","21:02:47","Monitoring Started"]},
{"id":"5","cell":["08\/12\/11","20:51:40","Communication Established"]},
{"id":"6","cell":["08\/12\/11","20:51:40","Monitoring Started"]},

As you can see from my Javascript. I have a test json data that corresponds to the json being sent from server. The Test data has no problem being rendered. Also I have tried changing jqGrid datatype. Again both work for test data:
datatype:'json'
datatype:'jsonstring'
I don't really mind about being able to page the data in the table. I just want to be able display the data and update it every 5 mins. I will do the updates once I get the basic data to display.
Any help appreciated.
Thanks in advance.

I have Googled till my fingers bled and I cannot find anything that matches my needs, which are:
- admin can provide templates (backgrounds) for the cards
- users can customise the card with text (font style and colour)
- users can upload their own photos (minor editing e.g. crop) to insert into the cards
- user can purchase a printed card via credit card payment
Seeing as this kind of e-Commerce has been around for a while now, I would have thought there were some systems to purchase that can provide this functionality?
