+[1:51:51][@centhusiast][Q: Are you going to implement the PNG writer?]
+[1:53:12][@centhusiast][Q: Does the Windows API use Hungarian notation?[ref
+    site=Wikipedia
+    page="Hungarian notation"
+    url=https://en.wikipedia.org/wiki/Hungarian_notation]][:language]
+[1:54:04][@recyrillic][Q: We had a yellow ~4coder flash today. Did we know about that color of flash already?]
+[1:54:53][@lucid_frost][Q: Do you think you still improve a lot as a programmer (as opposed to when you first started)? I'd be curious to know if there are specific things you work on to keep improving]
+[1:59:30][@skytrias][Q: Is it hard to write a level editor? What are the steps? I just want to set positions via mouse, save them so that they're used once exited]
+[2:00:10][Demo the game's asset editing :UI][:"asset system" :run]
+[2:02:34][@gayonara][Q: What do you mean by better :language?]
+[2:04:56][@centhusiast][Q: I really like your programming style of returning a struct from a function and I have been using it a lot. Is it true that it was not possible to return a struct from a function in the early days of C?][:language]
+[2:06:52][@basedyam][Q: If you were making a game with a lot of text on-screen, what text :rendering technique do you think you'd go for?]
+[2:08:43][@spranklz1][Q: How do you visualize your logic so easily? Sometimes I'll write a complicated function and it will take me, potentially, hours to debug (or fully understand); but that never seems to be a problem for you]
+[2:11:22][@se5a1][Q: I keep running into problems that I cannot figure out, but if I drop it and come back to it at a later date (weeks / months), I can sometimes figure out what's going wrong within 10 minutes. Any suggestions on how to improve my problem solving in this regard?]
+[2:14:59][@centhusiast][Q: What font do you recommend for a native desktop app? A font that looks pleasant to the eye. I have a hard time finding one. Thanks for your help!]
+[2:15:43][@flightlesshippo][Q: What's the hardest programming problem you've found yourself dealing with?]
+[2:16:03][@nickito97][Q: Do you ever use Valgrind? Would you recommend it for C (or maybe C++) code? Is there a decent Windows alternative?][:profiling]
+[2:17:42][@ud_0][Q: What language / environment do you recommend for introducing young kids to programming?][:language]
+[2:21:23][@nickito97][Q: Do you think learning to program with C is a bad idea?][:language]
+[2:22:00][@overture2112][Q: How often do you work on random small projects that aren't work-related (i.e. not [~hero Handmade Hero], Molly Rocket stuff, etc)?]
