• Is there a max size for POST parameter content?

  - by l3dx

  I'm troubleshooting a java app where XML is sent between two systems using HTTP POST and a servlet. I suspect that the problem is that the XML is growing way to big. Is it possible that this is the problem? Is there a limit? When it doesn't work, the request.getParameter("message") on the consumer side will return null. Both apps are running on tomcat

• What are the downside of not having an index.html file to some directories

  - by Pennf0lio

  Hi, I'm curious what are some effects/downside of not putting an index.html file to your directories (e.g images). I know when an index file is not present to a directory, files inside that directory are no longer private and will be visible to the browsers when point (eg yoursite.com/images/). Aside from that what are some big effects to consider? and how to properly secure them. thanks!

• Does the NSManagedObject instance still float around in space when it turns into a fault?

  - by mystify

  Or is turning into a fault the same as deleting that thing completely? I mean... is that guy then just still alive as a super lightweight object with no big data inside, or is it actually deleted? Or: Is a fault an object in memory with low footprint, or is that a "virtual object that COULD be there, but isn't yet"?

• Should I move this task to a message queue?

  - by Fedyashev Nikita

  I'm a big fan of using message queue systems(like Apache ActiveMQ) for the tasks which are rather slow and do not require instant feedback in User Interface. The question is: Should I use it for other tasks(which are pretty fast) and do not require instant feedback in User Interface? Or does it in involve another level of complexity without not so much benefits?

• efficiently convert string (or tuple) to ctypes array

  - by Mu Mind

  I've got code that takes a PIL image and converts it to a ctypes array to pass out to a C function: w_px, h_px = img.size pixels = struct.unpack('%dI'%(w_px*h_px), img.convert('RGBA').tostring()) pixels_array = (ctypes.c_int * len(pixels))(*pixels) But I'm dealing with big images, and unpacking that many items into function arguments seems to be noticeably slow. What's the simplest thing I can do to get a reasonable speedup? I'm only converting to a tuple as an intermediate step, so if it's unnecessary, all the better.

• Does having more methods in a class mean that object uses more memory at runtime

  - by frinkz

  Say I have one class ClassBig with 100 methods inside, and a second with only 10 methods ClassSmall When I have objects at runtime ClassBig big = new ClassBig(); ClassSmall small = new ClassSmall(); Does the larger class take up more memory space? If both classes contained an identical method, does the larger class take longer to execute it?

• What is the most efficient way to use Core Data?

  - by Eric

  I'm developing an iPad application using Core Data, and was hoping someone could clarify something about Core Data. Right now, I populate my table by making a fetch request for all of my data in viewDidLoad. I'd rather make individual fetch requests in my tableView:cellForRowAtIndexPath:. Can anyone tell me which is more efficient, and why? In other words, is it much less efficient to make lots of small requests as opposed to one big request?

• Fix a font size for .NET GUI

  - by Dmi

  Hi, Depending on the font settings (DPI and such) on the user's computers, I can have text become too big to fit in a button and moves down to the next line (wrap), so if it is a small button that says "Do xyz", it will only show "Do" unless I increase the height on the user's computer, but it looks fine on mine. Is there any way to force it to stick to original font size?

• Collision free hash function for a specific data structure

  - by Max

  Is it possible to create collision free hash function for a data structure with specific properties. The datastructure is int[][][] It contains no duplicates The range of integers that are contained in it is defined. Let's say it's 0..1000, the maximal integer is definitely not greater than 10000. Big problem is that this hash function should also be very fast. Is there a way to create such a hash function? Maybe at run time depending on the integer range?

• Is passing a struct value to a method by-reference in C# an acceptable optimization?

  - by Arc

  Say I have a struct: struct MyStruct { public int X public int Y } And a method in some class that is iterated over many times elsewhere: public bool MyMethod( MyStruct myStruct ) { return ... } Is changing the MyMethod signature to the following an acceptable optimization? public bool MyMethod( ref MyStruct myStruct ) If so, how much of an advantage would it really be? If not, about how many fields would a struct need for a big enough advantage using ref this way?
