[0:26][Recap and set the stage for the day]
[1:25][handmade_shared.h: Consider what we must implement in FormatStringList()]
[4:51][handmade_shared.h: Begin to enable FormatStringList() to handle decimal, hexadecimal and octal integers \[see Resources: C++ Reference\]]
[11:14][handmade_shared.h: Introduce U64ToASCII()]
[13:38][Blackboard: printf]
[16:47][handmade_shared.h: Implement U64ToASCII()]
[18:57][handmade_shared.h: Enable FormatStringList() to process the data returned by U64ToASCII()]
[20:28][Run the game and see our integer printouts]
[21:21][handmade_shared.h: Enable FormatStringList() to handle write back for the %n format and obey flags[ref
    site="C++ Reference"
    page="printf"
    url="http://www.cplusplus.com/reference/cstdio/printf/"]]
[27:11][handmade_shared.h: Enable FormatStringList() to handle AnnotateIfNotZero and introduce OutChars()]
[30:17][handmade_shared.h: Enable FormatStringList() to handle Prefixes]
[35:14][Run the game and checkout the printout]
[35:47][handmade_shared.h: Enable FormatStringList() to handle UseWidth and UsePrecision]
[38:34][A few words on this approach of boiling down complexity to simplicity]
[39:06][handmade_shared.h: Continue enabling FormatStringList() to handle UseWidth and UsePrecision]
[46:30][handmade_shared.h: Enable FormatStringList() to handle LeftJustify and PadWithZeros]
[49:04][Run the game and see the beautiful printout]
[50:38][Homework: Enable FormatStringList() to handle floating point values[ref
    site="Marc Andrysco, Ranjit Jhala, Sorin Lerner"
    page="Printing Floating-Point Numbers: A Faster, Always Correct Method"
    url="https://cseweb.ucsd.edu/~lerner/papers/fp-printing-popl16.pdf"]]
[53:32][handmade_shared.h: Make FormatStringList() only create temporary buffers where necessary, and enable it to obey precision for the %s format]
[58:42][Run the game, see that the strings print backwards and hit the assertion in FormatStringList()]
[1:00:06][handmade_shared.h: Make FormatStringList() correctly increment the At, run the game and note that the strings are backwards]
[1:00:37][handmade_shared.h: Give FormatStringList() the ability to choose whether or not to reverse the characters]
[1:02:02][Run the game and admire the beautiful printout]
[1:02:17][handmade_debug.cpp: Play with the formatting in DrawTopClocksList(), running the game and seeing it all working fine]
[1:04:58][Q&A][:speech]
[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]
[1:12:27][@neres909][And again. Just let me know if you see it[ref

[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]
[1:29:12][Wrap it up][:speech]
