• What does Silverlight offer?

  - by Maurizio Reginelli

  I'm working with C# and WPF and I would like to study something related to web programming. I already know HTML and CSS, and since I'm working with WPF, I am wondering if going into Silverlight is a good choice to start web developing. Can it be a substitute of server-side programming languages, like PHP or ASP .NET? What do you suggest? Thank you very much

• Core Animation: resizing layer from just one side on iPhone

  - by Jonathan Sterling

  I want to animate the resize of a CALayer. It needs to expand from the left (the right side needs to stay put). Setting the anchorPoint will make resizes work this way, but once I start animating, it doesn't behave the way I want it to. Does anyone have a suggestion? Thanks, and sorry for the noob-question.

• Dummies guide to locking in innodb

  - by ming yeow

  The typical documentation on locking in innodb is way too confusing. I think it will be of great value to have a "dummies guide to innodb locking" I will start, and I will gather all responses as a wiki: The column needs to be indexed before row level locking applies. EXAMPLE: delete row where column1=10; will lock up the table unless column1 is indexed

• MySQL app with Cassandra in mind

  - by SODA

  I am planning to make a web app which will eventually use Cassandra. But now that I don't have it and don't have server(s) to run it from, I'd like to start by using MySQL. The question is, is it possible to structure data and queries in such a way that it would be fairly easy to later port it to Cassandra? Main idea, I guess, would be writing MySQL queries that would be possible to change to same Cassandra queries. Maybe you have a better suggestion?

• celeryd dead but subsys locked

  - by Jeames Bone

  I get the message 'celeryd dead but subsys locked' when I check if celery is running. I get a [failed] message when trying to stop the service, and as soon as I start it I get this message again. I have deleted the var/lock/subsys/celeryd file which doesn't help at all. I noticed that the PID and log files are not being created in the specified place either, but the service is starting with an [ok] message. I am running CentOS.

• Managed code (C#) vs Matlabs and C++ for speed

  - by dotnetdev

  Hi, I am about to start developing an edge detection system (once I've read through a couple of books, which I'm doing so at good speed), but one thing I am wondering is the speed of an app like Matlabs (which can compile code to C++) vs AFORGE.NET for edge detecton. Is unmanaged code generally faster? Thanks

  Datatables has an option to select the number of records shown per page. The default value starts from 10, 25, 50 and 100. How can I change it to start from 5 instead of 10? 10 records is a bit too much and takes a lot of space in my current design. Thanx! http://datatables.net/

• MySQL: automatic rollback on transaction failure

  - by praksant

  Is there any way to set MySQL to rollback any transaction on first error/warning automatically? Now if everything goes well, it commits, but on failure it leaves transaction open and on another start of transaction it commits incomplete changes from failed transaction. (I'm executing queries from php, but i don't want to check in php for failure, as it would make more calls between mysql server and webserver.) Thank you
