Re: IDEs and the death of the command line interface

it just seems to me like the majority of the real work isn't going to benefit, and most of the rest (in my experience) actually suffers from "stop helping me dammit!" syndrome when I use a full-fledged IDE. This summarizes why I've started to gravitate towards text editors instead of IDEs...

Getting a second bachelor's online? (In CS)

I have a bachelor's in pure math and a master's in applied math, and I currently have a pretty good job. But the industry I work in is tumultuous, so I worry that massive layoffs may come without warning. Long story short, I'm starting to seriously think about getting a second bachelor's degree to m...

Re: Does anyone feel like previous levels don't prepare you?

But it also depends greatly on their high school as well as their own individual work ethic. Many people come out of high school without...

Re: Confusion on question concerning matrix norms

Thanks, I greatly appreciate it. I just finished a kinda-sorta proof of it just now, one that needs to be really tightened, maybe even thrown out. But, I do understand the concept now, and I see why it has to be true; just having a little trouble articulating it.

Again, thanks!
