I really wanted to make this post because you guys helped me out so much. I honestly thought I was stupid and maybe the entire major wasn't for me. But all the motivation I got in the comments helped me see otherwise. So let me tell you, I took my first 'object-oriented programming' in Java this semester, and I got an A! I know this was just a basic course, but I'm really happy that I didn't give up and more importantly that I believed in myself (thanks to you guys<3). I even joined a programming club! Thank you all so much for the support you gave me, and I hope this helps anyone that was in my situation.

Unlimited budget: what software would you buy?

Posted: 02 May 2019 05:32 PM PDT

So I work on campus as a TA for our computer science department and have been given the task of building a wishlist for new toys and tools for the next semester. My professor specifically told me to find some software to add to the list. What would you buy if you could?

Feel free to suggest hardware as well.

We're a CIS/java programming focused lab.

I've posted here before but I've been working on a new model for the decision tree system. It seems to be working better now but would appreciate feedback!

I'm using a similar process to ID3 / C4.5 but the main issues have been around how to optimise for missing data. An older algorithm I wrote from scratch was performing much better and I couldn't work out why. Anyway, I've started using the three sigma rule to both detect outliers in the resulting matches and also to decide how many nodes to test for branching the tree. This took some tweaking but is working better now.

Would appreciate feedback!

How to convert a negative decimal number in Hex without going over the binary digits?

Posted: 02 May 2019 02:45 PM PDT

Can somebody help me out?

So my task was to convert - 17 in hex, my result is : 0xFFEE is this correct?

But my Professor said, there is no need to convert it into Binary digits etc. you can go right ahead, but HOW?`
