    Music recommendation is a case where you really do want to overfit your training data, even at the expense of generality -- every single manually marked favorite should be in the play list, even if the sample seems bizarrely out of place.

    When doing exploratory research, there is a tension around optimization. Let it run for a couple hours, our optimize it to speed up the runtime and increase experiment count, at the expense of increasing the chance that there is an implementation error.

    It would be interesting to have some kind of massive corpus statistics on color distribution to pick the best range for chroma-key transparency for video.

    You might be marked down for it on an exam, but not explicitly cleaning up many classes of resources and just exiting the process to let the OS do it is often completely reasonable, and the high performance thing to do. Apps that don't exit instantly get a glare.

    Lately I have been writing a lot of "isolationist code", where I avoid all utility and convenience functions that might be available outside system libraries. Somewhat bulkier, but rather pleasant.

    This applies in games -- trading off a high advance for a high royalty because you are confident you are going to sell well may leave the publisher with an argument to instead promote a similar title that they have less royalty cost on. A high advance motivates them!

    While I vigorously defend the right to work harder than most people think is reasonable, this *IS* a great point.

    When shooting 180 VR, try to make your scene composition "V shaped", with the closer objects in the center, otherwise vertical disparity on nearby objects off to the sides will be uncomfortable.

    I like that! It is probably a good time for some soul searching if you find you are engineering "bulletproof shoes" to combat shooting yourself in the foot.

    I try to keep a positive attitude -- I cheer when we don't pull the trigger after carefully aiming at our foot.

    Every year now, I wistfully think about how fun it would be to just show up at with some brand new 8 bit code. I know I don't have time to do a real project, but maybe just a demo...

    Many of Rich's observations in the surrounding hundred+ tweets seem overly cynical (granted, my viewpoint would be conductive to naivete), but early Id Software days of massive bonuses did cause some pathologies that even socially-oblivious-me could notice.

    Heard a rule of thumb today: 100 mW of power per GB/s of main memory traffic in a modern SoC. That seems plausible, but does anyone have pointers to surveys of measured data?
