[56:02][Q&A][:speech]
[56:32][@Miblo][When we come to do the AI system, do you think it'd be reasonable to give the dudes a "gather lunch" behaviour?]
[56:50][@insofaras][What did you have for lunch?]
[57:24][@doritosranger][Imagine that you're young again and you're eating your lunch and you can choose between a C and Java-like language in what you can work with memory in much C-like way but that language would say you how to implement some ideas (like a Python is about line offsets, which is not good I think)? What would you choose then and why?]
[58:42][@evraire][During HandmadeCon will there be an organised lunch at the Campfire BBQ?]
[59:04][@assnburgers][Does Emacs offer more syntax support than what I am seeing at the moment?]
[59:36][@Ikkir_Isth][Is there anything that could be considered a "free lunch" in low level optimization?]
[59:47][@cubercaleb][Fair warning: The optimizer might store the strings in the same place which will break the whole GUID thing]
[1:00:13][@btnGames][Do you suggest programming should be snacked upon throughout the day as an alternative to a 3 course code feast?]
[1:02:28][@insofaras][Why do you think that there have been no good new languages since C? Are all the language designers out to lunch these days?]
[1:04:13][@PookiesRevenge][Do you feel there's a perfect balance between test-based coding, or more efficiency / optimization? Or do you prefer one over the other?]
[1:06:39][@assnburgers][What are your thoughts on clang?]
[1:07:31][@TheMaxS_][I think he meant string literals, like the -Og flag, I think]
[1:07:41][@Csixone][What do you think about Unity, etc.?]
[1:09:49][@z3rky][What's been the biggest hurdle you've had to overcome so far on this endeavor?]
[1:10:03][@killerfred3000][What do you suggest that people who are in the first year of C++ do as projects for coding throughout the day? (Feel free to skip if you've answered this before)]
[1:11:21][@jessem3y3r][Have you seen John Cleese's talk on creativity? If so, what are your thoughts on it?]
[1:11:36][@insofaras][How many more features will the debug system get? It already eats most other engines' lunch]
[1:12:25][@LeXxXiNgToN][Do you feel that taking calculus 1/2 is needed to become a good programmer?]
[1:13:31][@TheMaxS_][It was actually the -GF flag for the MSVC compiler. It enables string pooling, lumping all string literals into a read-only portion of memory so it only stores one of each different string]
[1:14:42][@ImJustRoids][Do you think there really hasn't been a good language since C, period? Or just that there haven't been any good languages that do what C can, like a good "competitor"? For example, if someone needs a small app, use C regardless or some higher languages are good for that (in your opinion)?]
[1:16:00][@insofaras][What if it doesn't pool strings and two same string literals get different addresses? Would the system lose its lunch?]
[1:17:06][Pseudonym73: Note that "good language" is relative to what you're doing. I've done things in Prolog that I wouldn't want to do in C]
