[58:05][@abnercoimbre][Give us a sec]
[58:25][@garlandobloom][I tried to explain to someone that a color is just a uint32 and I am not sure I got it across]
[59:01][Blackboard: "Color" -> Ambiguous term!]
[1:03:46][@Robrobby][You added Textmetrics into the struct and then decided to alloc it - why? And whats the benefit?]
[1:05:02][@ijustwantfood][About the language having different fonts. Would this apply to added packages by other people?]
[1:06:00][@garlandobloom][I'm talking about in terms of how the GPU cares about the color of a pixel, as opposed to a struct with float r,g,b,a. Which is not really necessary for a buffer thing]
[1:06:22][Blackboard: GPU \~ CPU]
[1:14:07][@An0nymal][Do any systems ever represent light as an actual frequency and change that value based on interaction with the simulated environment?]
[1:16:28][@cubercaleb][If you take in user input at some point will you worry about blocking Unicode control characters?]
[1:16:44][@Robrobby][So you care about the stack memory. When would you start to really measure it, or is some gut feeling enough? I would never had that idea before not getting an actual error]
[1:17:15][@TheSizik][What is HDR?]
[1:18:51][@EnemyMouse][Do you think there will be a time when CPU and main bandwidth is fast enough to replace GPUs entirely, going back to the days of software renderers?]

Cinera 0.7.0 Update Add output parameter to all of hero/code, hero/intro-to-c and hero/misc, preserving the current URLs while allowing different .hmml filenames, notably for hero/misc which now gets sorted chronologically.

Fix some incorrectly converted annotations Also apply some :speech categorisation 2018-03-07 21:48:09 +00:00			`[57:35][Q&A][:speech]`
