| What is the point of inverting a binary tree? Posted: 29 Aug 2020 08:45 PM PDT It might be obvious but for someone like me who primarily does web development and just general programming, I cannot see the point of inverting one. [link] [comments]  |

| Posted: 29 Aug 2020 10:27 AM PDT I've been stuck reasoning about this problem recently. Let's take the traveling salesman decision problem as an example: Is there a path through a graph G which visits every node once and whose edges amount to a cost less than C If I want to produce an "yes" answer to this problem with a nondeterministic machine, my algorithm is simple: nondeterministically grab nodes from G and the sum the weight of the edges between them, and if the total cost is less than C, yield "yes" and accept, otherwise loop or whatever. This is clearly polynomial (linear) in the number of nodes in G. However, I can't figure out a way to produce a "no" answer to this decision problem in polynomial time. The problem of proving that there isn't a path with a cost less than C seems to run into the same problem that the generalized traveling salesman problem has: any algorithm needs to do work on every possible path to prove the result. I don't think that you would be able to do this in polynomial time, even nondeterministically. Am I thinking about this wrong? Or is my concept of NP-complete wrong, and that we don't have deciders which run in polynomial time nondeterministically for NP-complete problems, just recognizers. [link] [comments]  |
| Posted: 29 Aug 2020 10:52 AM PDT Apparently the C compiler compiles C source code into assembly code, which is specific to one CPU architecture and is not portable. (Assembly code then gets compiled into machine code aka binary code. I think one assembly compiler is called gcc?) The Java compiler on the other hand compiles Java source code into Java bytecode. Unlike assembly code, this code is still portable. It is taken by the Java virtual machine and compiled to...? What? Is it first compiled to assembly, which then gets compiled to machine code? Or does the Java VM compile straight to machine code? I've seen both stated online and I'm not sure which is correct Another way to phrase the question is whether "assembly code" is synonymous with "C bytecode" Please correct me if anything I said was wrong [link] [comments]  |
| Posted: 29 Aug 2020 05:22 PM PDT I am a developer who never studied computer science, but the field interests me and I would like to learn more about it. Every explanation I found about the micro controller was one of two things:
I think what would help me understand is comparing with computers, specifically SBCs. My understanding of MCUs currently is that they're low power and low cost, but can only run one program over and over again, and cannot do complex things like load an operating system. What I would like to understand is what complexity are MCUs missing that forms the limitations that prevent MCUs of being full computers like the Pi. Thanks in advance! [link] [comments]  |
| Which skill is good for the future? Posted: 30 Aug 2020 03:44 AM PDT Hello, I need advice about select a good skill for the future but I don't know which field is good!! I very like Virtualization and development a hypervisor like Xen, but I don't know how can I start and which skills are needed. Most of hypervisors written in C, but I heard C\C++ are not useful in the future because of Rust-Lang and Linux kernel wants use Rust-Lang too. I'm thankful if anyone share opinions here. Thank you.

| What career choices would I have if I pursued a PhD and MBA? Posted: 30 Aug 2020 01:22 AM PDT I'm looking to get into Georgia tech's computer science PhD program with a focus in artificial intelligence. They also offer to earn a degree on the side as well which is the MBA which I plan on being in management of information systems. What career choices would I have if I completed this program.
