    Help students learn the C programming language and data structure with visualizing the execution of C code

    Posted: 29 Jan 2020 03:20 PM PST

    Hi folks, We released a cloud IDE with the unique feature that none has -- visualizing the execution of C code. You can see how data structure is built statement by statement. I wrote up a page to explain how it can help students learn C (and data structure), https://www.cee.studio/educator.html

    It works for C++ too, but C++'s visualization need some fine tune because it really allocates/deallocates a lot of memory for some seemly simple operations.

    Is a distributed database system defined as one with replication, partition or both?

    Is a distributed database system defined as a database system whose data are replicated, partitioned or both across multiple computers?

    Is a parallel database system defined differently from a distributed database system?

    Thanks.

    Is a minor in computer science good enough for an artist?

    Posted: 29 Jan 2020 10:03 AM PST

    I want to major in studio art but i want to get a minor in computer science so it can put me in a reliable job in software/computer design i think? Is that enough expierence?

    Any ideas for a capstone project? I have had several ideas rejected and I'm not very creative

    Posted: 29 Jan 2020 06:34 PM PST

    Hello, I've been trying to work on my capstone project but have been unable to get any of my proposals approved by the directors.

    • I proposed building a stock market predictor using LSTM and Boltzmann machines and comparing its results with the $SPY, but I was told it was trite and likely not going to outperform even the most conservative indexes.

    • I proposed building a daily fantasy football team builder, studying different artificial intelligence and applied statistical methods to find the best predictor of weekly performance for players based on standard and advanced statistics (RNNs, different forms of regression, SVMs, etc), and using linear programming to pick the best team possible based on your league's positional and budget constraints. Again, I was told it was too trite and it was difficult that I could do something better than what's already available (apparently they expect something to be either a novelty or something that outpaces the market).

    We don't have a course that guides us through the process of writing a proposal and developing the project, nor we have official guidelines for it. It's "expected" that your work serves as proof of what you've learned throughout your career and is more complicated than a project for a regular class. In that sense, projects that deal with machine learning, blockchain, distributed systems and IoT seem to have an advantage over the rest because they are seen as "novelties" (though in my case it seems that I picked overdone subjects).

    Do you have any ideas I could work on? I'm not interested in blockchain and working with IoT is complicated in my country due to import restrictions.

    Stupid question: Why DTIME ⊆ DSPACE?

    Posted: 29 Jan 2020 08:55 AM PST

    I've tried to understand this "simple" statement, and I've seen it explained basically as:
    In T steps you can touch a maximum of T cells on a turing machine, so the space used is at maximum T (and can be lower). This is crystal clear to me, but then why is DTIME a subset of DSPACE and not the other way around?

    If space is bounded by the time, shouldn't it be DSPACE ⊆ DTIME?

    guidance need for my first project

    guidance needed for my first project

    hey every one i have to make a project for my class although iam really not new to programming this is going to be my first big project i am planning to make a web vulnerability scanner basically the idea is that you give the web app a url and it tells in what way your site is vulnerable i am planning to scan the top 10 owasp vulnerabilities . but i really dont know where to start and what all modules that i should include i have to make it in 5 days any guidance will be really appreciated
