attaining a skill later in life should be more common, props to you! most people just start doing a whole lot of nothing when they retire, but you decided to do something you found interest in.

nice ! thank you

LOL. I love the music too

Sager no u are a miserable fuck. Bitch hole.

Joe L Yes

Maybe late but check out vacuum tube. Its like a light bulb but a special one. It acts like a transistor. It controls the light that is passing through. 1 if on 0 if off. Now connect a bunch of it together you can create a gates. And gate. Or gate xor gate.

Hey! Yo man, thx for the words, really really appreciate it. I'm glad the videos are helpful and I will be doing my best to keep making them.

+Dave Xiang your videos are dope. They are easy to follow and understand. I'm very much an analog girl in a digital world. Meaning I like to take notes while I listen to content. Your videos allow me to do that without feeling rushed. Thank you

yea i'm killing the music in all future videos.

+alexander babich You are right. First you have to remember that when you break 0s and 1s down to their basic level, they are actually just electricity. For RAM or your main memory, you can think of it as a huge array of 1s and 0s. The only way they keep their state is that electricity is flowing through them. If the electricity stopped all the RAM would go back to 0s. The instruction is sitting in memory and the program counter is pointing to it. I think you might be confused in how this is "sent" to the processor. Actually, the processor reads the values at this specific address and it recognizes it as a machine instruction. The program counter is ALWAYS pointing to memory that has valid processor instructions. If it's ever not pointing to that kind of memory, things are gonna go bad and crash the processor. The instruction itself has a special sequence of 1s and 0s that the processor recognizes and will behave a certain way to. Nothing is really transferred, but the flow of logic and electricity inside the processor changes based on various values (1s and 0s) of those machine instructions. The instruction in memory will represent ADD or SUBTRACT and the processor will react to it.

+alexander babich hey man whats up! amazing to see classmate and former colleague/friend @Dave Xiang right in one video. awesome video Dave :)

+faisal farooq Thanks dude. Damn small world

+Dave Xiang Now that I'm thinking about it my problem was that I was viewing the software as what's displayed on the screen lol. If I just think about it as always being electricity then it makes a lot more sense. Of course the computer doesn't need the display to do anything. All we are doing is basically controlling a gigantic electrical circuit.

+faisal farooq hey man! Good to hear from you!

+The Riddle Ah yea, I thought about it, but teaching programming is pretty tough to do in a video. I think the best way is actually through books, a course, and fiddling around with it on your own. I can maybe do a video on how to like get set up with python. I can probably do some stuff on like general programming concepts but I wouldn't really be able to get into the details in a video. Also a part of the learning processes is just struggling on your own. The more struggle the better the reward. haha

Alright I will keep that in mind.

+Dave Xiang Is there an online, preferably free course medium that you prefer for general self-study of programming and scripting languages?

+BOSSDONMAN Hey, check this out www.edx.org/course/introduction-computer-science-harvardx-cs50x Free, completely online, intro level course from Harvard. I think they know what they're doing =P Good luck.

yea, that's a pretty complex topic. it depends on what's in the text file. it's either compiled down to machine code with separate applications like GCC (languages like C/C++) but it can also be just interpreted as text by an interpreter(python3/ruby2x)

Dave Xiang Thanks.

No, they're not really the same. The context switching in this video is process context switching. The OS scheduling different processes to be run. If you're in a terminal and execute a script, those are two completely separate processes. This is all the stuff you on your task manager, or activity monitor. Recursion is a programming technique, usually contained within a single program or process. Recursion is just a programming technique to get something done. Just like using a loop is a programming technique. That is the common use of the word recursion, unless you're referring to something really different. Hope this helps

Thanks for your answer. You and a couple other channels are doing a lot to provide direction to people trying to develop in the wide field of development. There's a lot in the way of basic coding tutorial, but not much in the way of helpful counsel. I understand what you are saying. It just reminded me of what I remember about what happens when in the process of recursion, and wasn't sure if somehow the processes were related. The way for each function call the state of the previous function is reserved in memory, and revisited in the unwind when the base case is met. I admit that I have to brush up on the details of what actually happens..

Functions calling functions and preserving state is done via the "callstack". A program using recursion (makes a lot of function calls) would utilize the call stack often. You should google it and check it out

+kenrenjamrio Jamir Yes, HTML is all you need to hack computers.

Don't forget about CSS, which is mandatory for hacking. But yeah, first start off with HTML like Kon suggested.

How original.

Yes, if you want to do that, go do that. DiRT, I don't call out people often, but please don't disparage random people. This person is probably in like high-school, or younger, who just has some aspirations for a job. If you need to be sarcastic, you can call me out instead of replying to random people you don't even know. Stop being a bitch, or don't comment at all on my videos.

Dave Xiang hmh, i truly enjoy your videos and didnt expect a reply from you : ) I didnt mean to sound mean but its such a common "dream" and none of them even have the slighest clue to what it even is or what it takes to do so, he/she does mabye not even know if its 2D, 3D, Sound, consept art or codeing he/she wants to do. Being a game dev is not a LAN party with friends where you play games all night, its work, ofcourse if he/she wants to play games all day playtesting could be it, but i doubt that is what the dream is, playing the same level over and over again for days. Offtopic: Im wondering if all you know is "required" to program good programs, i get its a vague question becourse it depends on what the program is designed for but how much of the stuff you talk about on your channel is "super top tier" knowledge that is not important to know for the hobby programmer? -In ohter words, how much is learned through education, like a carpenter as an example, where i live a carpenter spends 20/40 weeks in a school + 4 years in a real shop to be a real carpenter and doing that time he is learning lots and lots of things and tricks that the normal hobby woodworker might not know or even need. I myself dont want to work as a programmer but do it mostly becourse i have an obsession with knowing how things work from the ground up and i spend alot of time on the computer, so having such a "small" grasp of whats going on behind the scences is annoying to me. You seem to know ALOT about everything in a computer and i must admit that you impress me with the amount of knowledge you have, not alot of people do that to me on a few topics, and i hope my question made sence, im not sure if i can explain it diffrently. Keep doing what you are doing! :)

Thanks for your reply. Yes, I agree a lot of people want to become a game dev because they like games, and really have no idea what it could be like. I was only worried because short comments like that which you wrote in like 1 minute can really be a bummer to someone who is young. As for "super top tier" knowledge, I really don't think the info I'm giving is super top tier at all. I'm a little different perhaps since I majored in electrical / computer engineering which is not very close to software engineering. So I come at it from a different angle. But all the info I give here is really basic. I think most people who know about those topics in details would have much more to say. They'd probably get offended by how much I dumb it down. I studied ECE but somehow through work/life... I just started getting into software. You are right in that a lot of this stuff isn't really required to become a programmer. I don't think you really have to understand the ins and outs of a computer to do programming well. My goal is to just give people a little bit of a taste of what else is going on. Hopefully it's interesting or at least makes people curious.

Dave Xiang it atleast did for me, but i spend too much time on the pc :) Thanks for the reply btw.

+axon magnus Yea no problem dude. I think one key thing to finding inspiration is to use programming to help you do something you really love. Use it to help you with something you already like -- good luck bro

+Anthovv7 ikr ;) ! thumbs up for this asian

*****​ Ikr! This is a nice asian
