• _REQUIREDNAME always nil

  - by Nali4Freedom

  I'm trying to use the method for naming a lua package after the filename mentioned here, however _REQUIREDNAME is never defined. For example I have these two files samplePackage.lua: print("_REQUIREDNAME: ", _REQUIREDNAME) return nil; packageTest.lua: require "samplePackage" And when I run packageTest.lua it outputs > _REQUIREDNAME: nil I also couldn't find any mention of _REQUIREDNAME in the Lua 5.1 Refrence manual, so was this removed from the language, or am I missing something?

• A nuts and bolts reference to C# performance and memory use

  - by phil

My aim of learning this is to get a better understanding of how increase the performance of an application and get a better understanding of how the C# language works.

• Get all Vector2 Points Within Radius

  - by CheapDevotion

  I am looking for a formula that will give me all of the Vector2 Points within a certain radius given the center. Essentially what I am trying to do is change the color of each pixel in a 256 x 256 texture that is within a certain radius from a specific pixel (Using the Unity3d Game Engine). Programming Language doesn't really matter, as I can probably convert it to something I can use.

• Pin Control in HCS12

  - by Brian Lindsey

  A HCS12 microcontroller I had to buy for a class I had recently taken has 40 pins on the back side of it. The class was merely about computer organization, and so unfortunately, we never had a chance to cover all the capabilities of the chip itself. Now that the class is over, I have been thinking about using the to familiarize myself with the assembly language. I haven't found any sources that cover pin control and was wondering if anyone could possibly provide me with a hands-on pin tutorial.

• Globbing in `git checkout`

  - by yar

  Is there any way to implement globbing in git checkout? It would be great to be able to use git checkout re* or even to have tab completion in the shell. I'm using zsh, but an answer that is shell independent would be great. Note: I realize that this is kind of a pipe dream, so... if I needed to implement this myself, must it be done in the shell language itself, or could it be done in, say, Ruby?

• Learning Recommendations? Classroom? Tutorials?

  - by cdg

  Hi there. Does anyone have any recommendations for a class (online) or tutorial that teaches android programing for dummies? It's frustrating knowing exactly what you want to do and no idea how to do it. Something that uses basic language and explains each line in detail to help a person remember how to do it later. Any suggestions would be great. Thanks.

• How to calculate the cycles that change one permutation into another?

  - by fortran

  Hi, I'm looking for an algorithm that given two permutations of a sequence (e.g. [2, 3, 1, 4] and [4, 1, 3, 2]) calculates the cycles that are needed to convert the first into the second (for the example, [[0, 3], [1, 2]]). The link from mathworld says that Mathematica's ToCycle function does that, but sadly I don't have any Mathematica license at hand... I'd gladly receive any pointer to an implementation of the algorithm in any FOSS language or mathematics package. Thanks!

• Is it the best practice to extract an interface for every class?

  - by the_drow

  I have seen code where every class has an interface that it implements. Sometimes there is no common interface for them all. They are just there and they are used instead of concreate objects. They do not offer a generic interface for two classes and are specific to the domain of the problem that the class solves. Is there any reason to do that?

• Encrypt hashed passwords?

  - by Industrial

  Hi everyone, Is it common sense to encrypt hashed&salted passwords that are stored in a database with a strong encryption (AES 192 or so) or are we just aiming for the stars? Of course, the encryption key will not be in the database itself, but will be kept at a safe place. Thanks a lot!

• One UI for two business objects

  - by JC

  I have an order edit and quote edit screen that are very similar. I want to try to avoid code like this: if (order is Order) SetupScreenForOrder(); if (order is Quote) SetupScreenForQuote(); But maintaining two screens is not good either. If I create some common interface between a Quote and Order then how do you deal with fields like OrderNumber or QuoteDate? What's the best way to handle this?
