• Index a mysql table of 3 integer fields

  - by Doori Bar

  I have a mysql table of 3 integer fields. None of the fields have a unique value - but the three of them combined are unique. When I query this table, I only search by the first field. Which approach is recommended for indexing such table? Having a multiple-field primary key on the 3 fields, or setting an index on the first field, which is not unique? Thanks, Doori Bar

• Remember JVM state before executing a specific instruction.

  - by user559064

  I am working on a testing project using mutating technique. My project requires to manipulate a Java classfile and re-execute the classfile multiple times for testing. My implementation need to re-execute the whole system again after one manipulation, and that is not efficient. I am wondering whether I can save the JVM state right before executing a desired instruction in the classfile, so that I can start from that state after each manipulation. Thank you.

• Is there a way through the Visual Studio IDE to move buttons between ToolStrips?

  - by Eric

  I have multiple ToolStrips with buttons on my form. I'd like to move some buttons from one ToolStrip to another. However, the Visual Studio IDE is not allowing me to drag the buttons off of a ToolStrip. I could go and edit the designer file for the form, but I try to avoid that as much as possible. So is there some way to do this through the IDE?

• MySQL: How to do a conditional update?

  - by Tom

  Hi, I'm trying to a create an update statement along the following lines: TABLE car: id | owner_id | type | status An owner can have multiple cars. UPDATE car c SET c.type = 1 WHERE c.owner_id IN ($ids) AND c.status = [1 IF IT EXISTS, ELSE 0] $ids is reasonably small (under 50 values). It seems simple but I can't seem to get my head around it because I can't use a SELECT subquery with an UPDATE to the same table. Anyone? Thanks

• Are parallel calls to send/recv on the same socket valid?

  - by Jay

  Can we call send from one thread and recv from another on the same socket? Can we call multiple sends parallely from different threads on the same socket? I know that a good design should avoid this, but I am not clear how these system APIs will behave. I am unable to find a good documentation also for the same. Any pointers in the direction will be helpful.

• How can I automatically refactor my classes to use the default namespace for the folder they're in?

  - by Daniel Schaffer

  I've been playing around with the structure of my project, and I'd like to reset the namespaces of my classes to what the default would be. That is, the default namespace for the project, plus each of the folders in the hierarchy. It's not as simple as just find + replace, since I've both added and renamed some folders, and files from some namespaces were split into multiple other namespaces. I'm using VS 2010.

• Java Multi threading - Avoid duplicate request processing

  - by seawaves

  I have following multi threaded environment scenario - Requests are coming to a method and I want to avoid the duplicate processing of concurrent requests coming. As multiple similar requests might be waiting for being processed in blocked state. I used hashtable to keep track of processed request, but it will create memory leaks, so how should keep track of processed request and avoid the same requests to be processed which may be in blocking state.

• How to track how many times an iPhone app is opened?

  - by Jason

  I am building an iphone app and would like to keep track of how many times it has been opened so that I can prompt the user to do certain actions after it has been opened X number of times. I have thought about storing a variable in Core Data which I update every time it is opened, but this seems like a waste since it is a singleton data, not multiple instances of an object. What is the best way to store data like this and access it without slowing down the app opening time?
