Confused on the simplification of this boolean expression: Posted: 04 Feb 2018 01:23 AM PST First year computer science student here, I'm kinda stumped with simplifying this boolean expression: ~(m * ~n) + ~n It is supposed to return true, but the closest ive been able to get it to is ~(n * m) * 1 What are the laws/steps I need to use to get it to return true? Edit: Here is my full procedure, where did I go wrong? ~(m * ~n) + ~n = (~m * n) + ~ n = (~n + ~m) * (~n + n) distributive law = ~(n * m) * 1 Edit: Thanks guys, I see where I went wrong. ~(m * ~n) + ~n = ~m + n + ~ n = ~m + 1 = 1 Don't know how I didn't see that before, too tired I guess : \ submitted by /u/7th_Spectrum [link] [comments]

What can I do to become a more desirable candidate/student? Posted: 04 Feb 2018 02:19 AM PST I'm a first year undergraduate studying CS and Maths. I'm fairly experience in Java, and a beginner in HTML, CSS, PHP, mySQL, Ruby and am going to attempt to self learn C. I'm going to be taking a year before my final year of my degree to do a placement but I wanted to know what I can do to become a more desirable candidate. I will be competing with my fellow classmates, as well as students from universities better than me. What can I do to become the best candidate? I have read a lot of people saying to do projects but I always get stuck at what kind of project to do in terms of ideas, and complexity. Any and all help is appreciated!! EDIT: By candidate I'm mostly referring to a career in software engineering or maybe an industrial placement submitted by /u/15150776 [link] [comments]
