[1:40:43][Q&A][:speech]
[1:41:03][@macielda][Q: Have you tried lldb? I use that at work and it seems to be stable]
[1:42:20][@Rounin][Q: How come the shaded debug window with the graphs makes transparent pixels around the main character white?][:"debug system"]
[1:42:45][@mallesbixie][Q: Why is the "there is no file" there if it's in the way all the time?]
[1:43:00][@jimerinorustlerino][@handmade_hero If you need to run a bunch of regexp substitutions on huge chunks of your codebase, how you go about it?]
[1:45:55][@ivereadthesequel][@JimerinoRustlerino you need Q:]
[1:46:33][@somebody_took_my_name][Q: There was this issue with the glyph count printed the wrong way around][:"asset loading"]
[1:46:56][Fix the font printout PrintContents()][:"asset loading"]
[1:47:18][@vtlmks][Q: Not really a question, but why EFI? What problem did they make up to have EFI solve?][:firmware]
[1:47:56][@vtlmks][Q: Yes, the BIOS standard][:firmware]
[1:48:19][BIOS, EFI (Extensible :Firmware Interface) and UEFI (Unified EFI)][:speech]
[1:53:23][@darksprites][Q: Bit of an off-topic question: I found your talk about GJK (which was really great!) and implemented it for my project but now I don't know what to do to "resolve" collisions when I detect them. What should I do?][:collision]
[1:54:54][@pythno][Q: Can you give advice for someone who wants to drop out of college (CS undergrad) and just finally get a programming job? Or is it a big no-no nowadays to do so?]
[2:03:17][@longboolean][Q: I am a bit confused by your answer, because I have booted from USB on pre UEFI systems. Am I missing something?][:firmware]
[2:05:12][@ivereadthesequel][Q: Can you give an overview of how you have structured your web programming in C? I've heard you mention it in some stream on how you made certain components behind the [~hero Handmade Hero] website in C or at least more-sanely programmed than most web frameworks. It really interests me, could you give some more info?][:"web development"]
[2:10:39][@jimerinorustlerino][@handmade_hero How about learning some online courses at python or something, and contributing to open source at GitHub (documentation fixes)?]
[2:10:46][@jim0_o][Q: You talked about people needing to know C++ to be hired for programming jobs these days. Did you mean OOP C++ with compile times linked to lunch-breaks? Do you think you would need to bone-up on newer C++ to do such a job?][:language]
[2:14:02][@cylvtwitch2][@handmade_hero How can you create a interesting portfolio for backend developers? I can't make fancy sites because I know nothing about design]

[2:25:02][@jimerinorustlerino][@handmade_hero Have you read "Out of the Tar Pit"?[ref
author="Ben Mosely and Peter Marks"
title="Out of the Tar Pit"
url=https://github.com/papers-we-love/papers-we-love/blob/master/design/out-of-the-tar-pit.pdf] It seems to resurface lately for some reason]
[2:25:09][@grimjoey][Q: Have you checked out kore.io (web server written in C)?]
[2:25:42][@uplinkcoder][@handmade_hero: libmicrohttpd is pretty good, as far as I can tell]
[2:25:49][@vikingcoder][Q: Do you have any advice for a programmer having trouble to adjust to a OOP way of thinking on the job and how to cope with or handle patterns. Thank you]
[2:26:28][@pythno][Q: Follow-up question: What kind of projects would be interesting for recruiters to look at? For example, at the moment I am working on a 3D rasterizer in x86 assembly using mode 13h with a DOS emulator. I don't know if that is interesting, because it is so legacy-like but I like doing it and reading the Michael Abrash stuff about it][:rendering]
[2:28:19][@uplinkcoder][@handmade_hero They can't tell you because then you could just try mails and see if they are subscribed, leading to data breach]
[2:29:36][@mattiamanzati][Q: Your subscribe form is not GDPR compliant. You need to add an unchecked-by-default checkbox with "I want to subscribe" text and add double verification emails]
[2:33:00][@thecodedragon][GDPR has a section dedicated to it[ref

page="GDPR Email Marketing"

[2:36:57][@jecosm]["If you have not previously unsubscribed, a confirmation email will be sent"]
[2:37:45][@maccod][Q: If he unsubscribes, he has to accept the terms again (a checkbox) when he enters the email address and wants to subscribe again]
[2:39:03][@vateferfout][Q: Why not just have an FAQ with the fact that if you don't receive the subscription mail and have unsubscribed before, you have to send a mail?]
[2:39:26][Propose responding identically to email addresses which have already been put on the mailing list or unsubscribed][:speech]
[2:41:11][Close it up][:speech]
