    Bell Labs current equal.

    Posted: 11 Sep 2020 02:37 PM PDT

    Bell Labs was the hub of so many key inventions in both software and hardware field. It contributed to so many different areas in such a huge amount. Tens of nobel laureates came from that fruitful period from Bell Labs.

    What is the current equal of Bell Labs?

    What are the inputs and outputs of Karnaugh map method for minimizing propositional formulas?

    Posted: 12 Sep 2020 02:05 AM PDT

    I heard that truth tables are used for simplifing the boolean expressions in an if-then command (https://old.reddit.com/r/compsci/comments/iqwxyh/six_years_as_a_professional_developer_and_yes_i/g4vckf4/), and Karnaugh map was also brought up in the discussion (https://old.reddit.com/r/compsci/comments/iqwxyh/six_years_as_a_professional_developer_and_yes_i/g4urk87/).

    Wikipedia says:

    The Karnaugh map (KM or K-map) is a method of simplifying Boolean algebra expressions.

    In propositional logic, what are the inputs and outputs of K-map method? Specifically

    • can K-map simplify all formulas, or just some? What kinds of formulas can K-map simplify?

    • Does K-map guarantee that the resulted formula must be logically equivalent to the input formula?

    • what (normal) form does K-map simplify a formula into?

    • Does K-map guarantee that the resulted formula must be completely in terms of some complete set of connectives? (e.g. any of ${\neg, \lor}, {\neg, \land}, {\neg, \lor, \land},\dots$?

    • K-map is said to convert a formula into some minimal or least complicated form. What is the criterion for measuring complexity of a formula?

    Is K-map covered in mathematical logic books? I have not been able to find K-map in logic books, but only in some digital circuit design books, which don't present it in a mathematically clear way.

    Thanks.

    Advice for new students just starting career journey

    Posted: 11 Sep 2020 01:31 PM PDT

    I just started out as a freshman at a large public school that's well regarded for CS. I've been programming for a few years primarily for my high school robotics team, and am pretty confident in core concepts but I have very little to put on a resume or my github.

    Searching through the internet, I've been overloaded with advice to work on personal projects, do leetcode problems, email professors for research opportunities, get involved with student orgs, go to office hours, ect. This all sounds like good advice, but it's a lot for a student just beginning. I really enjoy CS and want to build my resume and get a CS-relevant job asap, so what do you think students like me should prioritize right now?

    [R] OpenAI ‘GPT-f’ Delivers SOTA Performance in Automated Mathematical Theorem Proving

    Posted: 11 Sep 2020 08:37 AM PDT

    San Francisco-based AI research laboratory OpenAI has added another member to its popular GPT (Generative Pre-trained Transformer) family. In a new paper, OpenAI researchers introduce GPT-f, an automated prover and proof assistant for the Metamath formalization language.

    Here is a quick read: OpenAI 'GPT-f' Delivers SOTA Performance in Automated Mathematical Theorem Proving

    [R] Argo AI Model Jointly Plots Vehicle Pose and Shape From LiDAR Data

    Posted: 11 Sep 2020 02:34 PM PDT

    Autonomous vehicle systems have evolved their own digital approaches to shoulder-checking, leveraging data from one of their most common sensing modalities, LiDAR. Now, a team of researchers from Pittsburgh-based autonomous vehicle technology company Argo AI, Microsoft, and CMU have introduced a novel network architecture for jointly estimating the shape and pose of vehicles even from partial LiDAR observations.

    Here is a quick read: Argo AI Model Jointly Plots Vehicle Pose and Shape From LiDAR Data

    The paper Joint Pose and Shape Estimation of Vehicles from LiDAR Data is on arXiv.

    How hard is CS?

    Posted: 11 Sep 2020 09:24 PM PDT

    I know it depends on the person but having seen that many students change their major from cs, what makes this class so hard? What type of people thrive in this major (technical or conceptual people, perhaps both)

    I am a finance major at baruch and always wanted to learn more about computers but due to lack of knowledge I was always intimidated by the subject. I'm wondering if this is something I want to dwell myself into.

    Is it me or does MS documentation suck compared to others?

    Posted: 11 Sep 2020 10:57 AM PDT

    I currently started using java and looked at oracle's documentation and I couldn't help but notice how much cleaner and concise it was to me. Their layout is much easier to navigate through and their descriptions is less dense (imo). MS documentation can be vague or non-existent at times, and I feel like they deprecate something every couple months leading to inconsistent blogs from asp/blazor enthusiasts. But to their defense, I guess blazor is "cutting-edge".

    I haven't dug deep into java yet, nor have I looked at any of their walkthroughs yet (if they even have any) but I recall trying to follow some of MS walkthroughs for blazor, mvc, asp.net etc... straight from their site and I swear their documentation is all over the place, they'll explain one concept in one section one way and another way at a different place section. Maybe it's because there are different contributors for each section in MS (at least for the walkthroughs).

    Even with the OS, I feel like I MacOS operates more efficiently (in regards to W8/10, Win 7 is still king imo). My programs seem to execute faster in mac, the transition between apps and screens are smoother and overall the aesthetics of the ui just seem much cleaner and well thought out. Maybe it's because of the leadership change with MS, after gates and ballmer left it just seems like MS quality just went down the drain.

    Anyways that's my rant, and my experience. I'm just glad I started learning java, swift which forced me to get a MBP as it opened my eyes to all this.

    Unsure whether this is a knapsack problem.

    Posted: 11 Sep 2020 06:14 AM PDT

    Hi guys,

    i recently run into an optimization problem during work that seems like a knapsack problem with a certain constraint. Although at this point i don't think it is a knapsack problem at all. Basically, I have a list of objects with an y-axis value. Each object also has a different score/value associated with it. I want to get the a combination of the objects with length N with the largest sum of score. Where they also have to be a certain distance X apart based on their y-axis value. Which make it also seems similar to a house robber problem. My instinct also points to model it as a graph problem. But i'm very unsure on where to start.

    Edit: and whether a hueristic approach would be better time/complexity wise

    I have a huge problem about language design

    Posted: 11 Sep 2020 05:43 AM PDT

    I am fluent in C language. I even made a separate compiler similar to C ( Not C ) by C Language. But it is not OOP. I now want to create an OOP ( Object Oriented Programming ) language. But I do not know much about OOP. I have not used languages ​​like C++, C#, Python etc. So I have a problem. Do I have to learn another similar language ( OOP Language ) completely if I want to make an OOP language? Or is it enough to study its theory? Or is there another solution for learning OOP?

    What are some real time programming problems?

    Posted: 11 Sep 2020 05:42 AM PDT

    I have an interview where the 4th round is system test. It says that the candidate will be given a Real time programming problem to solve. I just want to know some Real time programming problems to practice.
