[1:04:58][Q&A]
|
||
|
|
[1:05:39][@neres909][I posted my question twice on pre-stream but both times it wasn't addressed. I experienced a bit of lag back then so I checked on archive what's up and it wasn't there. Am I doing something wrong?]
|
||
|
|
[1:06:31][@hayai][A few people in the twitch chat are asking about what level of math do you think is required to be an effective programmer]
|
||
|
|
[1:08:26][@internal_static_void][Casey, I understand that you are replacing all the string header functions (strlen, etc.). Are you not worried about optimization for these new functions you plan to write?]
|
||
|
|
[1:09:14][@tiferet418][I'm just trying to learn how to code. I'm following Stroustrup's book and he insists on teaching using math. All the good beginner books tend to assume math knowledge]

[1:14:26][@neres909][Hey. In one year I'm graduating and it will be time to find a job. All I always wanted was to work in the game industry but I have no work experience or projects that I am proud of to show as my portfolio. I guess you were leading programmer in your projects and you were responsible for making decision who to hire]
|
||
|
|
[1:15:52][@neres909][How you see people like me in this decision? Should I take whichever offer as a programmer I could find which might not even be connected with games, or maybe try to make the best game I can do in one year, or save some money and do an internship without salary (I didn't see any studios with a paid one in my region)? What's your opinion?[ref

[1:27:46][@neres909][Thank you for the in-depth explanation! I have one more Q: Since you're going on a break, can you trash out OOP just a bit so we don't get confused in the time you're not there, and stick to beloved compression oriented programming]
