    Can anybody help me develop more efficient study habits for CompSci?

    Posted: 11 Nov 2018 06:16 AM PST

    Hello everyone, so i'm a pretty new online CompSci student. I put in a lot of hours to get the coursework done an spend hours jotting down important notes from the interactive E-Books, writing down code that I want to memorize, and making dozens of flash-cards. The only problem is, at the end of every week, even though I'm putting in the effort, I don't actually get a chance to study because I spent all week making the flashcards, doing assignments, and writing notes.

    I'm wondering if it would be smarter to change my study habits, how I take notes, etc. Any advice would be great! I am maintaining a 4.0, but that being said, when the classes get more difficult, I want to be prepared.

    OS; How to decide which instructions are privileged to kernel mode?

    Posted: 12 Nov 2018 12:51 AM PST

    I have a midterm coming up and I noticed that I can't intuitively tell whether an action sends a trap or an interrupt, AND if it's supposed to run in kernel mode or not. I know that kernel mode has access to hardware related memory locations and generally system and hardware related operations should be privileged. But I still can't feel sure. Here are some example questions, I would really appreciate hearing your approach on answering them.
    - Are these trap or interrupt; Rotating mobile phone, pressing ctrl+C, issuing a system call, plugging in charger to notebook, terminating a program
    - Which of these are privileged; Memory access, causing an interrupt, reading from the disk, writing data to CDROM, opening a network connection, clearing memory, terminating a process

    Thank you for your help in advance.

    An Educational Programming Language that Runs in the Browser

    Posted: 12 Nov 2018 03:11 AM PST

    I have made an easy programming language that runs in the browser. A development environment and various tutorials are integrated in the browser application.

    I have already posted it in other subreddits - I hope it is not considered spam and it's useful for someone.

    kabas.online

    The language is kept simple in syntax and semantics. It has built-in commands for graphics. The browser application has an auto-formating and syntax highlighting editor and program execution tracer.

    There are the basic data types for integers, floats and strings and one-dimensional arrays of the basic data types. As in BASIC, the data type of the variable is derived from the name extension.

    You can define functions with value and reference parameters and local variables. So recursive programs are also possible.

    There are some interactive tutorials:

    It is possible to copy the runtime files to your own web server and to create your own tutorial.

    What Is Java Programming Language? Should You Learn It In 2018?

    Thesis subjects/companies

    Posted: 11 Nov 2018 10:48 AM PST

    I am on the end of my master degree Computer science at an prestigious uni in the EU and I need to write a thesis.

    Although it is an theoretical master I do not see myself doing research the rest of my life. I don't feel like doing a PHD neither. I am allowed to do this at an company, which I think is the best option for me because I want to start working after this anyway.

    But I really have no clue what kind of subject or kind of company i have to look for.

    The main topics I enjoyed in my master where:

    -Theoretical computer science: Graph theory, Constructing/proofing algorithms -> literally anything (approximations, GA's, exact). But I found it hard to connect this to real life problems/companies (Maybe something towards video streaming algorithms?)

    -A more applied topic which is close to the mathematical field Operations Research: Mathematically Planning and Scheduling of Jobs, trains, busses (whatever). But i don't see myself working at a big national train company (sounds boring to me)

    -I also got a lot of statistics and machine learning, but I do not like this as much (still interesting tho)..

    The actual country doesn't matter for my thesis, as i am willing to move for it. Any suggestions?

    Long-shot: Does anyone have the answers to "Computational Geometry: Algorithms and Applications"?

    Posted: 11 Nov 2018 04:39 PM PST

    My class's TAs communicated with the author himself, and he couldnt provide them. Do they even exist? (Sorry if this kind of post is not allowed. This is a last-ditch attempt to find these answers).

    (Edit) By answers I mean the solution manual. We are using 3rd edition but any will do.

    Are Parallel connections still used for anything?

    Posted: 11 Nov 2018 03:05 PM PST

    I have to teach Serial and Parallel connections as part of computer science for iGCSE, but since USB and SATA I wonder if Parallel connections are used for anything in a modern computer? Can anybody think of any good examples, I hate to teach my students defunct theory, but its still in the exam...
