    [R] Google Open-Sources 3D System That Shows How Places Looked in the Past

    Posted: 19 Oct 2020 02:35 PM PDT

    Historians and nostalgic residents alike take an interest in how cities were constructed and how they developed — and now there's a tool for that. Google AI recently launched the open-source browser-based toolset "," which was created to enable the exploration of city transitions from 1800 to 2000 virtually in a three-dimensional view.

    Here is a quick read: Google Open-Sources 3D System That Shows How Places Looked in the Past

    The associated paper Kartta Labs: Collaborative Time Travel is available on arXiv.

    UT Austin's online MS in CS?

    Posted: 20 Oct 2020 02:14 AM PDT

    Has anyone taken this? I'm really interested in it, as of now it needs no GRE, no rec letters and $10k for the total course's tuition fee, which is remarkable.

    Is it as good as GATech's online MS in CS? I've heard that degree doesn't even mention 'online' which still seems to be a major stigma, though that'll prolly change after this year.

    Side note: I am not American

    Trying to find some good icebreakers to employ...

    Posted: 20 Oct 2020 01:57 AM PDT

    Hi everyone, my committee and I have just been successful in relaunching the abandoned Computing Club at my University. We have our first meeting coming up and due to the pandemic, all of our events will take place online. Has anybody here got any good "icebreaker" ideas that we could employ on our first virtual meeting? Any help or guidance would be great :)

    Best Books on Propositional Logic?

    Posted: 19 Oct 2020 02:05 PM PDT

    Hey everyone! One of my favorite classes that I took in college was Discrete Structures as it really helped my proficiency in computational thinking and preparation for theory. Now that I'm out of college and have a job in the industry (I won't give specifics), I work with databases and SQL quite a bit for use cases of configuration, which leads to situations where I feel as though propositional logic can be used effectively, usually for sets. I find myself unable to recall how to formally write propositions and apply all the fun math to write proofs, hopefully to cut down on time spent solving a problem. We used an online book for the class that I took and I don't have access to those resources any more. Do you have a book you could recommend? I really do prefer to read understand the theory and math, so it doesn't need to be SQL specific.

    Do you use propositional logic and/or proofs in your professional work? What for?

    Recommendations for learning fundamentals of Computer Architecture and Organization?

    Posted: 19 Oct 2020 01:05 PM PDT

    I'm in my first year of CS and struggling in my intro to computer architecture class, which so far has covered topics on:

    • von Neumann architecture,
    • Harvard architecture,
    • instruction set architecture,
    • binary, hex, octal, decimal
      • conversions/addition/subtraction/multiplication/division methods;
    • IEEE 754, floating point arithmetic,
    • ALU, Registers, Commands, Memory, how commands are processed, Metrics( MIPS, MFLOPS), CPU Speed,
    • Amdahls law.

    What would be the best approach to learn all of this? What resources would be most effective to use? Basically everyone at my University says that they are struggling hard in this class.

    We have distant learning, so basically the professor just records a powerpoint video lecture and in a really monotone, hard to listen to manner talks through the slides and it's extremely difficult to understand what he is saying when you don't understand the subject well. One minute I'm trying my hardest to really listen and try to understand and a bit of it makes sense and then the next minute I have no idea what he is saying and I lose focus and it's super frustrating. I have no idea how I'll pass the exam, like I don't know how to study for it. The video lectures don't work for me, and the professor basically said that the materials he provides aren't enough to pass the exam and that we have to basically google everything to figure out the concepts ourselves but the subjects are so overwhelming I have no idea how to structure my learning in a way for me to really understand these subjects.

    Local search algorithms question-:

    Posted: 19 Oct 2020 06:51 AM PDT

    If elevation corresponds to an objective function, then aim is to find the highest peak-a global maximum.(I Can understand that if elevation corresponds to a cost, then the aim is to find the lowest valley as we would want the path cost to be minimum).

    Here is the copy from the book-:

    How Wolframalpha's sequence solver works?

    Posted: 18 Oct 2020 02:25 PM PDT

    So I was seeing this feature in wolframalpha where given some elements of a sequence, it will give you a general formula. From this wolframaplha blog link it says:

    Wolfram|Alpha can recognize millions of different sequences. Rules for the sequence terms are either recognized algorithmically or as part of the On-Line Encyclopedia of Integer Sequences (OEIS), such as 8, 14, 38, 68, 98, 104, 194, 224 ….

    But I do not think it is enough, what exactly happens is the underlying work?

    Relevant links to pointers will be appreciated and ( sorry if its offensive ) vague answers like "It uses an ML/DL model" is not the answer I am looking for.
