I found this a couple months ago and it was an amazing resource (thanks dmitrygr)! I ended up using atc1441's base station firmware[0] because it's a bit of a pain to actually pop open the case and get the programming pins on the

It's been a long while since I worked there, but IIRC one of the big issues at the time was that the symlink "support" couldn't actually work properly: - some users want symlinks to be synced as symlinks (and they might

I’ve been playing with Rust on the ESP32 using these tools on and off over the last couple of months or so, relying more in linking to the existing FreeRTOS/C HAL for accessing the peripherals. One thing I haven’t quite figured out: a

The compiler toolchain can cross compile to esp8266, but I think the pure Rust HAL is less developed there. If you use Rust to write components/code that link against the ESP-IDF, I’d imagine that would work? I have the toolchain in a

1. We thought about this at one point, IIRC, and various parts of Dropbox sync have been formally modeled. But CanopyCheck and Trinity are useful in part because they test the real, production code -- the hash-indexing bug that Sujay mentio

I'm not Sujay, but I worked on this system once upon a time too! (not anymore) 1. It does redo the minimization phase, but the actual execution is extremely fast, so this cost is minimal. Storing test outputs gets pretty expensive when

I can't speak for Slack, but it's not unreasonable to believe that a single machine's available output bandwidth (~10-40Gbps) can be saturated during a deploy of ~GB to hundreds of machines. Pushing the package to S3 and fetc

It depends on what you mean by checking all the boxes: Go is tricky if you run on diverse platforms and want to do a lot of FFI, since cgo overhead is significant. The type system in Go is also not very powerful, which is both good and bad.

As I recall, this was investigated at one point on Sync Engine Classic and is definitely a thing that folks were thinking about for Nucleus, for pretty much exactly this reason. The biggest challenges with this kind of work (not specific to

disclaimer: was on the team, but didn't write the article / don't work on this anymore Rust was adopted at Dropbox for some serving infrastructure use cases more than a year before the sync rewrite was started, which was abou

If you're interested in graphics, animation, simulation, machine learning, or other topics, knowing the concepts in linear algebra will be worthwhile. Most higher-level math will be easier for you if you have familiarity with vector ca
