Interesting! We interact with the low-level APIs too vs the SDK, also: an IO scheduler for request batching and conn management, request hedging, full MVCC transactions, etc. We st…

Curious how the DB startup with Dynamo at its core went. We use it heavily. The primary tricky thing for us at the moment is aligning pricing with workload value.

Do you have any of your fixes publicly available?

Regardless, that’s kind of the beauty of this project: term-keys generates the terminal config file based on all your bespoke keybindings for you. Would probably be easier to setup…

MacOS user here. So many times over the last decade I’ve journeyed to get terminal Emacs working with my litany of weird keybindings. But I always end up back in the GUI. I switche…

For simple high-frequency time deltas, I've found this function wins on the perf front: //go:linkname nanotime runtime.nanotime func nanotime() int64

Love the simplicity and elegance of the design to address this problem.

I mentioned this in another place on this thread, but a simple AIMD algorithm paired with a token bucket is surprisingly effective at dynamically adjusting to available capacity, e…

I’ve found the AIMD algo (additive increase, multiplicative decrease) paired with a token bucket gives a nice way to have a distributed set of processes adapt to backend capacity w…

I built a thread-safe rate limiting library for Go that's lock-free with zero allocations on the hot path. It features multiple strategies including classic token bucket and TCP-in…

Bazel is a fully reproducible and hermetic build system. A lot of painstaking work goes into it producing the exact same artifacts build after build. And that provides some interes…

I wish “Prevailing Time” would catch on. Eg PPT

Mergify just introduced a “speculative merge queues[1]” feature that does something very similar. [1] https://blog.mergify.io/announcing-speculative-merge-queues

That sweet, sweet traffic data.

I've always been curious about the general directory structure they use for this. Does anyone have insight?

I’m firmly on team monorepo, and I agree great tooling is an absolute requirement. We use Bazel + AWS CodeBuild with local caching. We have an average incremental CI build of our m…

The AWS Cognito User Pool Authentication Flow utilizes an augmented PAKE (SRP). I imagine there are a number of major sites that use Cognito along with the SRP auth flows baked int…

TLA+ specs explore all state spaces of concurrent processes. Avoiding state explosions is something you need to be conscious of when building those. The modeling required also take…
