The Next Generation of 2D Roleplaying Games

. I'll eventually have to learn it anyway. I plan on double majoring in Computer Engineering and Computer Science and taking extra theoretical physics courses (don't say it is a stupid idea, I want to work on quantum computers, robotics, artificial intelligence, computer architectures, and just anything computer research related) when I go to college. Personally, I am the type that rather take a lego making machine over a ton of legos. 
If you know what I mean.This is why:So why are people so scared of it? BTW, I have only done basic operations and using inline assembly.

It's programs like this that make me hate assembly. I hate that my university has forced me to learn three assembly languages thus far into my bachelors. The code above is for an AVR atmega128 chip to power the infrared receiver, using hardware interrupts. It's difficult as hell to remember what everything is on a piece of hardware I have no interest in ever programming for again.Code: Select all

something about making sure we understand what we wroteI would never say thats a stupid idea. I was a theoretical physics student before I was a Comp sci student. I can tell you though that you aren't likely to do much work with quantum computing. All the courses I did were based around quantum mechanics, partical physics, thermodynamics, relativity and a lot more that I can't even remember now. Also you end up doing a lot of pure maths courses.davidthefat wrote:I plan on double majoring in Computer Engineering and Computer Science and taking extra theoretical physics courses (don't say it is a stupid idea, I want to work on quantum computers, robotics, artificial intelligence, computer architectures, and just anything computer research related) when I go to college.

I'm guessing you were introduced to moving things around in registers and calling simple math instructions. Trust me, there's a shitload more to it than that.
Double majoring in Computer Science and computer engineering? Sorry, but I honestly would say that's a stupid idea. The two already overlap in almost half of the spectrum. I have never heard of a computer engineer not being able to get a job as a computer scientist OR an electrical engineer. CPE is broader than CS. Yes, you go into software less, but you learn a lot more about architecture and hardware.
Since a CPE can get a job as a CS, what is the point? You're wasting precious class money and hours. If you really seek a sincere pursuit of knowledge, this is still not a very intelligent alternative. I will ALWAYS recommend getting a master's as opposed to a double major. Masters are respected, result in pay increases, and are utilized in the work place. A double major is almost useless.
If you're regretting not being CPE (and choosing CS), just finish your degree and get a masters in CPE. It's really not that much of a change. And guess what? You haven't wasted another two years of your time and money for another undergraduate degree that ... sorry to say... is useless...
Great! Seriously! I would like a phD as well... So why would you waste time and money getting an EXTREMELY redundant double major like computer engineering and computer science when you could be furthering your education and obtaining a higher, more respected, more useful degree? There was a time when I wanted to double major in either mathematics or electrical engineering with my computer engineering degree. Just because I "loved the subject and wanted to pursue knowledge." Once you get into college and are introduced to the work-force, you realize that this is really silly. A dual major is literally a waste of time and money. You do NOT need a piece of paper saying that you know something to know something.davidthefat wrote:I'm aiming for the doctorate just sayin'.

Also, I have another bit of bad news for you. 90% of jobs are NOT research intensive, unless you work in R&D which is VERY rare. Only the best of the best work there, and you have to work you way up. How do I know what I'm talking about? I worked as a government contractor for Stanley Associates (fortune 100 engineering company) for the Army on the Redstone arsenal for about 2 years. I literally just interviewed with Boeing and Lockheed Martin (I graduate in two months), my father works as an engineer for NASA, and I have friends who work for Boeing, Lockheed, and all of those other big, private sector companies. It's just a sad fact that "research"--especially for newly graduates with nothing more than an undergraduate degree--is not marketable, not profitable, and not in a company's own selfish self interest.
If you are interested in an earnest pursuit of knowledge, aim for the same goal I'm trying to reach. Get hired by one of those high-paying, high-profile jobs. Do useful, meaningful work for them (with one undergrad), and 90% of them pay for your entire Masters and phD for free. If you "genuinely" want to get into research, your future almost certainly must be within academia. And trust me, it's at the GRADUATE level pursuing a Masters or phD, not as an UNDERGRADUATE wasting more time on redundant bachelors. The difference between undergraduate and graduate is literally the pursuit of a piece of paper to get you a job versus the pursuit of knowledge as an end to itself. You have much to learn, grasshopper.
Thanks for the info. Yes, I do have much to learn.Just to clarify I meant the theoretical physics part wasn't stupid not the double major, I agree that those two subjects are far too interrelated and doing both is redundant.GyroVorbis wrote: Double majoring in Computer Science and computer engineering?
