    What are some not so known books you have read and you can recommend?

    Posted: 05 Apr 2020 12:26 PM PDT

    When it comes to books, everyone is familiar with the likes of CLRS or Dragon book etc but what is that one book you have found and read that turn out to be a hidden gem? gave you a new perspective perhaps?

    How long did it take you to feel like you had valuable programming skills/knowledge?

    Posted: 05 Apr 2020 11:39 PM PDT

    I have been programming basically daily for the last year and a half and the more i program/learn the more less i feel like i know and that there's so much more that i don't know. How long did it take you to feel like you had valuable knowledge/skills?

    Questions regarding multiprocessors & false sharing

    Posted: 05 Apr 2020 08:07 PM PDT

    Hi, I am currently learning about false sharing in multiprocessors and have run across some questions I'm interested in:

    One proposed solution for the problem of false sharing is to add a valid bit per word. This would allow the protocol to invalidate a word without removing the entire block, letting a processor keep a portion of a block in its cache while another processor writes a different portion of the block. What extra complications are introduced into the basic snooping cache coherence protocol by this addition? (considering all possible protocol actions.) Furthermore, how would you change the code of an application to avoid false sharing? What might be done by a compiler and what might require programmer directives?

    TIA!

    What would I need to know to make a 'game' that lets you build a bread-board computer?

    Posted: 05 Apr 2020 07:09 PM PDT

    I've been looking at these types of things on youtube, but I have no way to acquire the components to get to fiddle with stuff like this myself. However, I do have a two-year degree in programming, and have made some progress in learning pygame (despite the lack of a tutorial for the language, or good documention on how each of its functions actually work). From what little I do know, I believe I could in theory make such a game. I actually did own a game like this long long ago. It came in a pack with a bunch of other old sim games (such as sim ant and sim music). Sadly, I no longer have that game and I have no idea what it was even called.

    Getting back on point, I believe I could make a game like this. However, I don't really know a lot about how computers actually work, or even electronics. I've been thinking about this using the simple example of an and-gate. It seems deceptively simple, but it really isn't. Should my program take into account how much power is going into everything (I was planning on requiring chips to actually be hooked up to power in my game to work)? What if I chain and-gates together? I really don't know. I know nothing about electronics other than you plug things into a wall and push a button to turn it on. Another problem is replicating the more elaborate chips you often see people using in homebrew computers. I have no idea if the wiring inside those things is proprietary or not, and with how elaborate they are my program may lag trying to simulate it. I also have no idea how memory storage physically works. What's actually inside a RAM chip? How does hardware process data coming from a storage device such as a hard drive? How do you make a multi-functional programmable computer? I don't understand how something that has no moving parts could perform multiple tasks.

    Yeah, I'm a complete novice at this. I don't even know what I would have to study to seriously make a program like this, or if I would have to make up my own chip designs? I really know nothing, even though I could probably make such a game easily if someone else was explaining to me exactly what it was trying to simulate.

    Is it possible to redo your Final year project, or fail it and be given a chance to redo it?

    Posted: 05 Apr 2020 04:59 PM PDT

    I am in my 3rd year of undergraduate, I am meant to hand in this work. But the work I have done is dog shit, and honestly not even worth sending in. Does anyone know if I am able to redo my final year project or been in a similar situation?

    edit: UK student

    Self-learning CS while stuck at home

    Posted: 05 Apr 2020 09:26 AM PDT

    Hey guys, I hope you're all safe and well during these times!

    Since I'm stuck at home for a while and at the end of 12th grade, I wanted to get a head start by self-learning CS since I will be a CS major at University in September. (A little background: I took AP CS at my high school 2 years ago which focuses on java. I don't remember most of the content but I can easily refresh my memory by revisiting my old notes).

    I've been doing a LOT of research and looking into different learning resources but I've no idea where to start. I see SEVERAL online courses (Harvard CS50, MIT OCW intro to CS, Stanford's CS intro, Stanford's 106A, Coursera, etc) and I'm honestly overwhelmed as I've heard mixed opinions about all of these courses (Ex: some people are saying CS50 is a great start but some are saying it's too hard).

    So I wanted to know what you guys think would be the best way for me to start learning CS so that I can be prepared for college in September (I've from now till end of August)?

    What do you do when an OSS software that you use has a nice but not so useful feature that is not working properly?

    Posted: 05 Apr 2020 01:08 PM PDT

    Edit: I understand that it is possible to have done one or more of these things, but this is just to see the usual/default mindset and understand how we can better the participation of people using OSS softwares. Or for that matter write more intentionally accessible software.

    Please take it with a grain of salt, this is not representative of everyone and every experience that you have had.

    Hey guys, check this link out. Does this algorithm solve X3C or does it only solve a special-case?
