I am having trouble on deciding whether to go for a computer engineering or computer science degree.

I am interested in both, but which one should I consider more of from a pragmatic and financial point on view?

Also which degree is more flexible and your opinions on the two degrees?

>> No.10675900

>>10675844

I'll preface this by saying I am an EE major so I can't talk about many of the specific course differences. As far as the overview, I can provide some insight.

EE, CE, and CS all exist on a spectrum of computing. EE is mostly hardware and some software. CS is mostly software and some hardware. The split for CE depends on your program. My school is skewed towards more software than hardware.

The reason I explain this is to emphasize that CE is less well defined. From what I've seen, most CE students get a little bit of both but really focus on software more than hardware.

By the definition of flexibility, CE is technically more flexible as it allows you to do either software or hardware. Realistically, there are many more software jobs than hardware jobs so CS has more scope.

The ultimate redpill however is that it really makes little difference in the end as the majors are so close together.

I'm an EE but I'm getting experience more related to strictly computer engineering 'defined' work. Also, from what I have seen, someone with experience in hardware (and EE) can learn CS more readily than a strictly software person can learn hardware.

This may have been rambling a bit but I hoped it help.

In short, pick CS if you want to avoid hardware engineering as much as possible. In the long run, it won't matter much.

Is the ability to feel pleasure something that can be depleted? Although I've been depressed and suicidal forever I can usually generate a few shots of pleasure from (you)'s and similar things, but there have been occasions in the past where I felt completely mentally empty. Not the oh I feel miserable empty but the it's totally impossible for me to feel anything good at all empty. If I was to do something like jerk of in this state I might feel the physical sensation of orgasm but not the associate pleasure.

Am I draining something physical in my brain to create this state? Some kind of neurotransmitter?

>> No.10675829

>>10675794
Yes. Habitiation is constant. The less unique a given experience is, the less total stimulus you can derive from it. Scientifically, this is called falling into a rut.

>> No.10675871

>>10675829
how do I fix this, is getting out and doing other things the only way?

>> No.10675908

>>10675871
No, there's plenty you can do indoors even to change your perspective. For me, I have no eye for design. My apartment is basically completely blank. All my stimulus comes from higher thought and reasoning. I'm a perfect candidate for things like surrogates, or perma-VR. I explore the mind, so the only times I get depressed is when I try to stop myself from thinking/creating new things or ideas.

Not everyone can live like that. Sometimes people need to change their furniture or rearrange the layout just to make things feel new. It's not about forcing things to be new, but just changing enough to make it feel that way. Everything, throughout all of human society, is an aesthetic decision. Who you vote for, what credit union you like, how the toilet paper feels, everything is a matter of taste. Some people prefer economical things, others prefer function over anything else, etc. There isn't one form of pragmatism, there are many. Singularity of purpose only occurs in small communities, probably no larger than 17 times the upper limit of Dunbar's number.


Or you could try new things, like hiking.

>> No.10675909

>>10675871
pretty much. but it usually happens naturally, when you can no longer stand your terrible emotions, you are compelled to go out and fix your life in some way, improve your condition in order to feel more pleasure.

>> No.10675920

Yes. The sex energy is the same as the life energy and is the same as pleasure. Why do you think babies are born from the male orgasm (semen)? That's your life, that's your soul. Every time you jack off, you lose the ability to have pleasure, and you lose a little bit of your life and become more depressed and suicidal. The ancient religions knew this. They knew that the virtue of celibacy/continence (which is really just retaining semen inside your body) led to a longer life and more contentment/happiness. People who masturbate are depleting their life force and end up depressed wrecks. Here, read this: http://www.dlshq.org/download/brahmacharya.htm

You'll get jobs quicker with Healthcare. My wife works at NYP Columbia, NYC, as a nurse. She works 3 nights week from 7:30 pm to 7:30 am,

She makes 120 grand annually with a little overtime. I will t take that over majority of engineering jobs working 5 days a week most likely making less money.

Also, agreed. nursing is one of the few low-difficulty jobs that probably won't be replaced by robots, since it involves so much face-to-face interaction and reassurance.

AI is a passing fad. Short of the over valuation we see from fad chasers in silicon Valley especially, AI has limited use case that Microsoft Excel.

Now, if robotics are to get enough traction, then will we see a lot of forging forward in reaching sentience.

The problem is all too often we're focused on the biomimetic aesthetics so much that we fail to discover possible advancements.

Until there's a radical departure from the logical pathology of AI, I'm sorry to say the reach is generations away

can professional CS guys tell me what are some cool nice projects to make to learn diferent topics in a CS degree that requires me to google and learn the basic topics like math, compilers, networking.

I feel like reading a 900 book about such CS topics to be a waste of time and I rather code the exercises without wasting too much time on the theory.

So far I come up with shit like:

>Data structures
code from scratchs things like trees, quadtrees, octotrees, linked lists, basic search algorithsm like sort bubble.
code from scratch an A* algorithm.

>Networking
basic chat app.
basic app that shows a twitch channel chat by giving an url link, or some app that renders a youtube video comments.
basic pong multiplayer from scatch.

>Linear algebra
do some 2D photoshop transformation tool I think.

>Computer graphics
A basic raytracer, a SDL demoscene demo.

>C
some basic text editor using C

>C++
dunno about what project to make for a modern C++

>trigonometry
a basic trigonometry calculator from mouse input positions.

>Functional programming
Maybe some calculator on haskell.

What are other projects that will teach me CS topics without reading a fucking textbook I don't give a fuck.

Think of air as a sponge with lots of little pockets between the atoms that can hold water vapor. When things get cold they shrink.
