• What should I do during the summer?

  - by zamN

  I have just recently graduated from High School and I am looking for something productive to do over the summer. I was thinking of possibly learning a new language that can give me an edge in school or a good project to pursue that will look good on my resume for future jobs. Also how would I go about getting a job right out of high school or interning for a company for the summer? Thanks in advance.

• What's the best UML diagramming tool?

  - by eplawless

  I'm trying to choose a tool for creating UML diagrams of all flavours. Usability is a major criteria for me, but I'd still take more power with a steeper learning curve and be happy. Free (as in beer) would be nice, but I'd be willing to pay if the tool's worth it. What should I be using?

• What is the best way to use whitespace while programming?

  - by Emmanuel Smith

  I'm fairly new to programming and from learning I have seen different ways of formatting code, comments, etc; and have been recommended on different techniques. I mostly program in C#, C++, and Java so I want to know what is the the best way to layout code so that if other people where to go through it, they would be impressed by how simple and easy to understand it is. I would like to know the same thing for commenting as well.

• Remove stateful EJB bean in client

  - by palto

  I'm currently learning EJB and as I understand when client gets a stateful session bean the server keeps it in memory(or passivates it) until the client removes the bean. Pretty simple, except nowhere I have seen any examples of how the client can actually remove the bean. How do you do that other than shutting down your client application? Or do I just have to implement a reset method in all my stateful beans if I want to start over?

• Dynamic adding HttpModules and HttpHandlers

  - by pokrate

  Hi, Is adding / removing HttpModules and HttpHandlers at runtime from a website a good idea ? I am looking at ways to make my website as dynamic as possible without uploading changed content all over again. Something like config files. Rule engines exist, but learning them seems like a pain. I might be wrong in my perspective. Please suggest possible ways to change logic in the code at runtime.

• Asp.net mvc small amount data storage

  - by Trimack

  Hi there, I am writing some learning tests (i.e. what's the answer for...; choose correct options...). Now my question is, how should I store them. SQL db seems quite an overkill, but I really don't know what would be the best choice if I wanted to select random subset of questions etc. Perhaps some simple xml files? Thanks for advice.

• Categorize the approximate shape of an array of Points in 3D Space

  - by user1295133

  I have a set of points in 3d space and I want to be able to categorize the shape that best fits them - cube, sphere, cylinder, planar (flat) etc. I've looked at supervised/machine learning but since I need first generate a large training data set that's not really suitable. My dream solution would be a java library with a wonderful magical function something like : public enum ShapeType { CUBE, SPHERE, CYLINDER, PLANAR } public ShapeType CategorizeShapeFromPoints( 3DPoint[] points ) However, any and all help will be appreciated. Thanks
