• [C++] Is it possible to roll a significantly faster version of modf

  - by John

  In an app I'm profiling, I found that in some scenarios this function is able to take over 10% of total execution time. MSVC++ 2008 compiler is being used, for reference... I don't recall if modf maps to a single instruction or if there is likely any way to make it faster. see also here for similar question on sqrt function

• How can I pass information between 2 different View Controllers?

  - by sagiftw

  Hi, This is a simple question: I have 2 different view controllers, and each one has its own data stored in its .m file. I want to take a value, for instance, an integer value (int i=3;) that is declared in ViewController1 and pass it to ViewController2, so I will be able to use that value in the second view controller. Can anyone please tell me how to do it? Thanks in advance, Sagiftw

• Multithreaded Applications

  - by j-t-s

  Hi All I have been reading the articles on MSDN, but my mind is dead (this usually happens when I read MSDN (No offense MSDN, but your articles confuse me at times.)), and I'm trying to do some "background work" in may app, but not sure how. It's just a single method. But the application hangs, and I have to wait up to 1 - 3 minutes for it to become ...unhanged? Are there any simple examples that are laying 'roun online somewhere that I can have a look at/play around with? Thank you all

• C# start a static thread

  - by user595605

  I have a Queue of items I want to process in a thread, and any instance of a class can add items to the Queue to be processed. My idea for doing this is to have a static Thread in the class that processes the items, the only problem is that I don't know where to start this thread, since I can't start it in its initialization. Is there a way I can start a static thread? Or should I be changing the architecture completely?

• Amazon EC2 pricing question

  - by Industrial

  Hi everyone, I took my first step today on working with cloud servers and chosed Amazon EC2 for this project. Since I am a bit of a newcomer on this, I didn't fully understand their pricing: What happens when a instance is idling with no connections being made. Does it still cost us money? It would be sad to have instances idling and costing us money when we do not use them... Thanks a lot!

• What's the best way to have functions share an array in Objective-C?

  - by editor

  I understand that in Objective-C you declare an array in the header file and interact with it in a class. So far I'm adding things and fetching them fine within a single function. I'm new to the language however and can't figure out how to share that array across other functions. I'd like to initialize array data in my viewDidLoad and access it from various functions later on. Is this possible and if so what's the best way to do it?

• finding if an anniversary is coming up in n days in MySql

  - by user151841

  I have a table with anniversary dates. I want a query that returns me rows of anniversaries coming up in the next 10 days. For instance: birthdate --------- 1965-10-10 1982-05-25 SELECT birthdate FROM Anniversaries WHERE mystical_magical_mumbo_jumbo <= 10 +------------+ | birthdate | +------------+ | 1982-05-25 | +------------+ 1 row in set (0.01 sec) I'd like to keep the query in the form x <= 10, because I'll use that number 10 in other parts of the query, and if I set it to a variable, I can change it once everywhere by changing the variable, and not have to re-write the query.

• Click to select from a list of tags in jQuery

  - by Michael Doornbos

  I'm struggling to find a tag selection UI for a rails app. Ideally it would be something like the selection here on Stackoverflow, or on Delicious or Digg. I want users to be able to select multiple tags with a single click. We're already using jQuery, so it makes sense to use something that takes advantage of that. I've used the selection ui in jQuery and I'm not thrilled about having users need to hold down ctrl to select multiple tags.

• Method to sort MYSQL results by an arbitriary letter (ie, show all rows starting with F first)

  - by Buzz

  I have a column of states, and, depending on the query, I want to order by results by a particular state, then by id (Asc or Desc, depending). For instance, I might want to show all rows with state "HI", sorted by ID desc, and then all the other rows, sorted by id desc. I was hoping I could do this in one query, rather than getting all my favored state results, and then getting the rest. Can I?
