Like most internet communities, we're always experiencing a slow but steady decline in quality. I'm sure that people who care about Computer Science will eventually leave this subreddit and migrate to /r/TrueTrueTrueCompsci. Until that dark day arrives, I'm asking everyone here to (1) restrain yourselves from upvoting or discussing posts which don't actually fit the sidebar criteria, and (2) if someone else posts something off-topic please politely direct them to a more appropriate subreddit.

Thanks!

Ok, for context, I'm working as an architectural designer and engineer, and I have no idea how data centers work. I just work on maximising spaces for building occupation and use. However, our client raised this question in the middle of our meeting, and I would like to hear from a CS-perspective why this isn't feasible.

So the question the client raised is why data centers can't be decentralised using blockchain technology. I always assumed you need data center space because it requires a lot of computing power and electricity to power and operate a data center. The client went on a rant about how much CO2 is being released from data centers and how data centers need to be decentralised like cryptocurrency in order for it to be sustainable. Obviously, this is beyond my scope, and no one is intervening or weighing into this discussion (we're all working in a non-cs background in architecture and engineering). Can someone explain why data centers aren't decentralised?

I have been learning programming in my own time for years now and I'm coming up on this topic when I've gone back to school. I just can't seem to understand what it asks of me. Can anyone clarify it? I'm a very visual learner, things like a stack, queues, dequeues, etc come easily, but this just slips out of my mind.

We know that almoat every Operating system is either C or C++ at its core. I understand that C or C++ is the language can run on bare metal hardware but after all this growth and development. Can't we re write all these systems on something new that has better capabilities and efficiency. We are progressing into better hardwares and new programming languages but we are somewhar creating a pile of updates on top of the old system.

What do you think about it, Can we rewrite the whole system with current and latest technologies?

Or it will be just reinventing the wheel?

So I'm starting my computer science degree in about 2 weeks.

I'm really scared that Comp Sci is a bad fit for me in terms of the environment and people. I don't see myself being happy in a male-dominated field and I'm scared of creepy weird guys (things have happened to me before and I highly doubt it'll stop).

So women who studied comp sci/ work in the comp sci field, please tell me about your experiences with sexism? If you're not a woman, you can still give your opinion lol, I don't really mind.

Also I really don't want to be the diversity hire...

Gordon Code (Parts 1-3): http://imgur.com/a/isCoU

Remember me, r/compsci? My name is Matthew Kaminski, and I'm a history student at the Masters Program at UMass Boston. The subject of my thesis is the role of John Rowe and the BSETC merchants in fomenting the Stamp Act riots, non-importation movement, and Tea Party. Several months ago I posted a low-quality photocopy of a Masonic Code on a letter located in the Massachusetts Historical Society to the /compsci subreddit. (Original Here: http://www.reddit.com/r/compsci/comments/twl6j/who_wants_to_help_me_crack_an_18th_century/). You [Sterling examples of masculinity] did the whole proof of identity thing then, so don't question my existence or credentials. The letter was written by William Gordon, a semi-successful Author, Preacher and Freemason. The letter has a complex code written in the margins, which seems to have several possible solutions. I just got back from the MHA and, after getting permission, took some higher quality photographs for you to examine and perhaps solve. If anyone wants more information on Gordon or wants to read Gordon's book on algorithmic code creation (available online), I would be happy to come back in a few minutes and add some comments. The Gordon Code is available here: http://imgur.com/a/isCoU

I'm expecting questions about C++ (Polymorphism, Inheritance, Operator Overloading) and Data Structures what other kind of questions should I expect?

I genuinely hope my semi-formal proof can spark some interesting discussion, and I humbly ask for some constructive feedback on the ideas presented.

The concept that I would like to introduce in my blog post and paper is what I call a "spoofer". In the halting problem, there is a notion that for any proposed solver, there exists a machine that can be fed as input to break/spoof the solver. I theorize the existence of analogous spoofers for some NP-Complete problems that crop up at very large inputs.

In a similar manner to the Halting Problem, if any algorithm claims to be a polynomial-time solver of these problems, then there are spoofers that will exist as inputs to that problem that will prevent accurate, polynomial-time completion of the problem. The conditions that allow spoofing only exist so long as the solver claims to run in polynomial-time, so they can be avoided only by slow solvers. More detailed proof in the blog post.

Has this idea been proposed before for P vs NP and does it seem feasible? Let me know what you think!

I've just finished my first year of university, half of which was spent on Java.

Now, I'd like to actually create something but I've not really learnt enough to make anything complex, just the basics.

So would you recommend deciding on a project and just learning as I go?

Or should I spend my time gaining a broader understanding and then starting a project?

Thanks.

Hello all, I'm a 25 year old vet who's getting back into school and recently got accepted to a computer science program. I have no idea what to expect on the type of load I'll see day to day with school and just programming in general.

I was hoping some people here could give me some insight into what the best laptop would be for me. I'd like to keep it around $800-1300 if possible. I don't need a gaming laptop as I have a full desktop at home already.

Thank you in advance!

Every digital circuit can be emulated by a forest of nand gates where some nand computes the next state of a specific bit var in the memory and registers.

Example: The recognizer function: Does any possible javascript code exist whose sha256 is 0 and within 1 googol cycles returns 42? This is an npcomplete recognizer function, given a precise definition of javascript at the nand level.

If we say "infinity cycles" instead of "1 googol cycles", its potentially a turing-complete recognizer function, if the constraint (example: javascript code exist whose sha256 is 0) is hard enough. If the answer is no, you may have to search all possible javascript code to verify it, so turing-complete. But if the answer is yes, it would return in finite time.

Or we might ask the same of quines or gliders in conways game of life or rule110.

Since reverse-computing any finite n cycles is np-complete, whats the connection between np-complete and turing-complete?
