The lab assignments are available (without solutions) to those who are self-studying from their accompanying book. Even if you haven't read the book, I'll urge you to try out their lab handouts (especially the Bomb Lab and the Attack Lab).

Shouldn't this be an 'Ask HN' ?

Off-topic: Do you have any recommendations for books or other resources for such game-dev postmortems? I remember that idTech's Doom and Quake were described in one such book, but I'd really like to read about some other major games.

Most MUDs/MUCKs that I connect to, have that kind of users who connect to simply hang around and chat, instead of roleplaying seriously, like most other players do. I've lately found myself resorting to these kind of gatherings (admittedly HN-like/geeky) for most of my socialization.

For users not interested in MUDs, I'd suggest looking at IRC channels which follow your interests.

<rant> The thread till here is a perfect example of how discussions/debates should be like on the web. Someone expressed an opinion, someone else expressed an opposing opinion (misinterpreting the first opinion). Both opinions, if interpreted correctly, are valid, and the person who misinterpreted admitted it. Beyond that, (and note this) the author of the original opinion also apologized for being confusing in his statement of his opinion. Well done! </rant>

Same for the XMPP based chat app for android, Conversations (although F-droid already provides a compiled package, so users don't really have much incentive to buy the Play Store version).

>Lots of music is most efficiently stored as MIDI, yet how many songs on iTunes are midi?

While storing music as its component instruments is indeed size efficient, converting existing music into MIDIs using some ML/AI algorithm is not yet effective. Vectorly seems to convert _existing_ raster videos into vector ones using some combination of computer vision algorithms.

Their android SDK (no release version yet) is available at their Github repo, and so are their bulk upload tools (for talking to their servers using, I guess, a pay to use API).

They've listed some uses for it — animated videos, e-learning (the likes of Khan Academy). While I doubt that animation would shift to vector video any time soon, it indeed would help e-learning a lot, speaking from the side of the content distributors (less size). The only benefit for end users might be faster streaming, but yeah, I agree that the average user can't be bothered about it.

Lithium, iirc, parses only epubs. Librera Pro parses a large number of formats, like PDF, epub, mobi, azw, djvu, and so on. It also supports auto-cropping of white margins in formats that do not support reflowing of text.

Oh hey, extremely sorry, new user here. Also, thanks for the tip!
