[1:49:18][Q&A][:speech]
[1:49:51][@vateferfout][Q: At the end of the y loop of the downsample, shouldn't it be SourceBuffer0 = SourceBuffer1 + PrevDim; SourceBuffer1 = SourceBuffer0 + PrevDim; and x and y advancing by 2?][:rendering]
[1:51:01][@mmozeiko][Q: You added a comment for handling big-endianness for residual value when calculating hash, but I feel it is important to mention that the same comment should apply also for *At dereferencing in the loop. Loading u64 from byte array will also be affected by endianness and hash value will be different][:hardware :hashing]
[1:51:50][Make the big-endian comment apply to the whole of CheckSumOf()][:hardware :hashing]
[1:52:39][@zrizi][Q: (Off-topic) Are you the founder of Molly? How long ago did you start working there?]
[1:53:02][@jim0_o][Q: Does Anna draw Vector graphics initially and would you consider rasterising vector graphics in the asset system or at startup for a game like this?][:art :"asset loading"]
[1:54:23][@nxsy][Q: What sort of precision would we be losing by doing the downsamples from each other and doing srgb->linear->srgb, rather than, say, doing the linear conversion at the start and keeping it in linear, and doing the linear->srgb only when writing out each file?][:"asset loading" :rendering]
[1:56:28][@zrizi][Q: (Off-topic) Any suggestion / resource about how to implement a :networking layer from scratch for massive multiplayer games?]
[1:56:46][@nxsy][Q: I guess that’s a fun thing for me to test out][:rendering]
[1:59:06][@ivereadthesequel][Q: (Off-topic) Just curious, are there any games that require more accurate or complex digital filters on the image than those of bilinear or other approximations? Like any sort of sharp low pass filter, etc?][:rendering]
[2:00:49][@centhusiast][Q: Could you explain again the rotation to the left in the bit pattern you used?][:hashing]
[2:02:01][@zrizi][Q: I was thinking about a shooter. But let's think that we want to support multiplayer (over network) for [~hero Handmade Hero]][:networking]
[2:03:01][@graemephi][Q: (Off-topic, a bit) Can you give a quick description of the filter you designed? I'm fine with heavy DSP jargon][:rendering]

[2:05:00][@frostyninja][Q: My girlfriend appreciates how much you hate on Microsoft and Windows (since I scream about it day in and out), but she said your keyboard sounds like someone's peeing in the next room and it has ruined my life]
[2:05:38][@zrizi][Q: But when client updates using server's incoming updates, assuming client simulates locally, it can create discontinuation if simulation diverged. Maybe in [~hero Handmade Hero] it cannot diverge that much, though][:networking]
[2:07:38][@vateferfout][You can just lerp between the client state and the server update][:networking]
[2:08:11][@jim0_o][Q: Would you need the brush strokes or would vector graphics from a conversion tool work? In Adobe Illustrator there is a quick and dirty conversion tool that I found works nicely for high-res cartoony graphics to vector graphics][:art]
