    (Question) Connecting Python, Graph Database, and Supporting Elements

    Posted: 12 May 2019 01:44 PM PDT

    Hi Reddit,

    I'm pretty confused about connecting services to create a real-time analysis system. Basically, I have a website via squarespace, and I want to make an environment where this website will display a realtime analysis on something (for example news)

    This is how i want it to work:

    My python code pull a set of . data from API -> this python code make some calculation and adjustment -> save it in graph database (neo4j) -> display it in my website

    Rinse and repeat every 10 - 30 seconds.

    How can I do this using python and neo4j (and additional services like AWS to run the code on cloud) ? I think I need a server to store the data(?). Pretty much very confused now. I apologize if this question is too newbie to be displayed here.

    Aspiring CompSci major...Failed Computer Information Systems SEVEN times ;_; (I know...)

    Posted: 12 May 2019 06:45 PM PDT

    Alright so spare me the roasting please, I'm well aware of how unbelievably stupid and pathetic this is.

    I'm a community college student for a few years now, working and scraping by. There's one class I've been taking since i started here- an entry level class, Computer Information Systems.

    Now, I know what you're thinking. "Maybe this class isn't for you" etc...

    The thing is, I can use Excel, Access, Powerpoint, Word, etc... fine. I'm more than competent with microsoft office, I know an elementary amount of coding (just moving past the basics in Python/Java) and I've been working on and with computers all my life. I think that's part of the issue.

    It's like I'm not taking the work seriously because I know how simple it is, and I'm always doing that sort of shit anyway, so I just put it off. and put it off, and off, and off, until there's like 7-9 hours worth of spreadsheets to hand in at the end of the semester, and I don't do them because busy with work/other classes, and I fail.

    Well, I just failed the 7th time. The final exam and all the semesters work is due in 6 minutes. I handed in everything up until the midterm and then just slacked off.

    I hate myself for this and I really am beyond ashamed, frustrated, etc.. It's just so unbelievably unnecessary and stupid.

    That being said though, what the fuck do I do about those 7 F's on my transcript for the SAME class, ESPECIALLY when I wanna go to school for Computer Science?! Forrget about it dude, that'll look like a joke. Applying to a fucking computer science program with 7 F's in a class that can be done by a 12 year old.

    It's the only class left I need to graduate with my prestigious Liberal Arts: Social Sciences and Humanities A.A. degree, and then I can start to applying to 4 years that I can't afford.

    I was thinking about maybe asking the Dean if those classes could possibly be removed from my transcript but honestly I highly doubt it.

    I'm gonna retake it 5/20-6/20 as a 5 week course and just knock it out and get the A, but still, even an A after that is just like...come on dude, SEVEN times? The thing is, I'm not bad with school whatsoever. I've been good about disciplining myself since High School for the most part, and I have B+/A in just about everything else. It's just this one fucking class that it's just so easy for me that I get despondent about doing it because it's so tedious and I already know how, so I swear to myself I'll do it later and I've done that more than a half dozen times now.

    So guys....wat do. If I wanna transfer to a 4 year for CompSci, I'm thinking my best option from here would be to change my major from Liberal Arts A.A. -----> CompSci A.S. I would only need to add like 10 classes which I can knock out in summer/Fall/Winter (3/6/3) which honestly would be dreadful since I want to get a move on things academically/etc... but It would at least show that maybe I'm competent in computers but just that that specific class had a weird thing with me.

    Proof of complexity problem PSPACE vs NP

    Posted: 12 May 2019 03:33 PM PDT

    % This is a proof that all n^2 x n^2 Sudoku is in PSPACE for Infinite Deterministic Turing Machines if and only if PSPACE allows Infinite Deterministic Turing Machines. % Usage: % prover9 -f pspacevsnp.tx > pspacevsnp.out % Use prolog-style names (initial uppercase is a variable): set(prolog_style_variables). formulas(assumptions). Sudoku(X) -> Pspace(X). % If X is in polyspace computable for Infinite Deterministic-turing machine, then X is reducible to (PSPACE). Sudoku(allsizes). % Sudoku is in PSPACE. end_of_list. formulas(goals). Pspace(allsizes). % Therefore, Sudoku is in PSPACE. end_of_list. 

    Well, the automated theorem prover proves that if Infinite Deterministic Machines(if allowed) proves Sudoku is in PSPACE. Seems, that I'm breaking a rule as I'm suspecting this is not allowed. What's your opinion?

    Update: Turns out its allowed. Turing Machines have infinite tape!!! https://en.wikipedia.org/wiki/Turing_machine
