I worked on a similar system at Plaid, but we used lightstep. The biggest challenge was on boarding engineers to the tool. It was also a bit of a workaround with respect to test flakiness, which we tackled separately. Still, I and many engi

I 100% agree with the central thesis that tests are about evidence-based correctness. I think keeping this in mind is important as a product and codebase scales since a lot of testing approaches shift in importance over time. The articles s

Highly recommend publishing this as a blog post and sharing as a post on HN so it isnt lost to the ether - hard to consume this as a comment but theres good nuggets in there

Sorry I should have clarified - by "refactoring APIs" I meant the sort of work that would e.g. be unifying all photo abstractions at Facebook behind a new service, not just refactoring package-level abstractions. That sort of work

I used to joke at work that the fastest, simplest way to get promoted to a staff engineering position was to finish a 1 yr refactor. Getting existing codebases to do new things is hard, and most of enterprise software engineering is basical

T+2 is an artifact of fund transfer settlement times isn’t it? Or to rephrase, why do we still have T+2 for equities?

As someone who has only read 1/3rd of Pearls book (for fun, just an engineer by day), this was a great answer and convinced me to pick it back up after surveying the non-Pearl world - thank you!

I might be biased by personal experience, but I think this has less to do with US regulation vs Europe and more to do with direct competition between tech firms’ equity value, notably late stage private companies and recent IPOs. A recent e

The OP is being cheeky with that comment - God as a first cause is really orthogonal to abrahamic religion and many arguments are in full agreement with the "original cause" being uncreated. OP is likely alluding to current popula

I have 0 brain HCI experience but can’t you take that 2 or 3 bits of information and then use time multiplexing to encode more signals? Eg if I can reliably switch between relaxed and angry at a rate of 100ms I get 2x the bandwidth every 20

Gotcha, it seems like you want to run backtests from within Prometheus for richer post-hoc analysis. That sounds like a normal use case, I often do fairly non-trivial post hoc analysis in Prometheus (e.g. Z scores and stddevs of metrics) si

By backfilling I assume you mean retroactively applying labels to a time series? Can you link to the thread with more context if you have it around? As a prometheus user myself at a 100+ eng org company I've never had a use case for a

First inspection of this made it seem like a modern reskinning of Ibn Khaldoun's Kitab al Ibar which also attempted to explain the rise and fall of empires[1]. Turns out the wiki page calls this out as an explicit source of inspiration
