    Database Schema Design Examples

    Posted: 29 Aug 2019 07:28 PM PDT

    Designing a database schema is the first step in building a foundation in data management. Ineffective schema design can creates databases that are heavy consumers of memory and other resources.

    The article provides an examples of an effective data schema for a data project based on PostgreSQL. This discussion will also provide a general foundation in data schema design: Database Schema Design Examples

    Updates to Incredicat, my attempt at a 20 questions style game powered by Cat AI

    Posted: 29 Aug 2019 06:41 PM PDT

    I posted this a few months ago and had some great feedback. I've put some work into the model and have just released the latest update. It uses a modified version of C4.5 decision trees and a load of other adjustments. Think it is working better now after some changes around the classification process. Appreciate any feedback!

    I Need Advice

    Posted: 29 Aug 2019 07:24 PM PDT

    Most people look at me and think "Wow! This kid is pretty smart! I think that I should look up to him for advice for a variety of things." However, what people don't know is that I've been trapped in life. I may have lots of general knowledge, but I seldom find ways to apply it to real life. For example, I play video games. Unfortunately, I'm very poor at video games, especially against other players. My question is, is this truly unfortunate, or is it just plain stupidity. I think that it's just plain stupidity. This is because I spend at least 5 hours a day, every day playing video games. I always play the same video game, and I'm still far below average.

    In recent years, I've chosen to take up programming. After all, I have all of the qualities programmers would benefit from. When I started programming (in HTML and CSS for those who are wondering) I struggled very much. Most of my friends (same age and started programming at the same time) were able to develop a stunning website with ease, while also knowing another language which I did not - JavaScript. I, however, had difficulty creating a simple taskbar, let alone a full stunning website. This drove me insane, so I spent the next year trying my hardest to master HTML and even more CSS. Still yet, I was far behind from my friends. I hadn't a clue as to why I wasn't going anywhere.

    Recently, I've decided to attempt learning JavaScript and completely restart My coding journey from scratch. Still yet, I couldn't even open the canvas without Khan Academy's ProcessingJS library. Very quickly, I decided that this wasn't for me, and I'd rather learn something that I could use to make, instead of present and learn to present when I came to that step in a more important project I had in mind. I heard that C++ was one of the most powerful languages in the world, so I tried that, couldn't even print out the classic "Hello World" (while following a tutorial) to the console without a build error. I can't figure out what's wrong with me.

    I need some advice. Is this a question for a completely different subreddit? Did I start with the wrong language? Where did I go wrong? I'm a kid, over 4 years away from going to college, so that's not an option. Also being a kid, I have very little money to spend. I'm sorry if this was a bit overwhelming, I just thought this would be a good place to ask. Thank you.

    Best hopefully open source books for understanding compilers and program structure. Thanks!

    Posted: 29 Aug 2019 07:47 AM PDT

    I'm interested not only in learning a PL, but how they work. In my reading I saw where a seasoned programmer said, If I understand structure and interpretation of programs plus compilers that it would make it much easier to understand a language to write the theory in. Which makes sense, the only issue is lack of money and the fact that I really don't want to spend yrs on this. So I figured a couple of good books could help me.

    Is it necessary to know Linear Algebra for my comp sci degree?

    Posted: 29 Aug 2019 10:32 AM PDT

    I took Linear Algebra my senior year of high school so I don't have to take it in college. However, I don't remember much from the class and can't help my friends who are taking it right now. Is it bad that I don't remember anything from the class or am I fine?
