janOsch··on Saving Three Months of Latency with a Single OpenTelemetry Trace
Thank you for pointing that out! You are correct, μs stands for microseconds, not picoseconds. I've corrected the mistake, and the update should be visible as soon as the CDN cache invalidates.
janOsch··on Saving Three Months of Latency with a Single OpenTelemetry Trace
Fun fact: it probably took more time to write up and refine the blog post than it did to hunt down that sneaky 40ms savings.

I'm the author of the post. You raise a good point about relative savings. Based on last week's data, our change reduced the task time by 40ms from an average of 3440ms, and this task runs 11 million times daily. This translates to a saving of about 1% on compute.
janOsch··on Monospace: A JavaScript demo in 1021 bytes, winner of the demo competition
It is amazing how much one can achieve with so little code. I would dare to say that such demos are a kind of...indie art?

janOsch··on AWS forked my project and launched it as its own service
In my mind there are two aspects on the matter:

License - what AWS did is "legal", most commercial software is built on top of OSS.

Worst possible outcome of this thread: the community will become scared of big corporations stealing their hard work - this will stifle OSS creativity.

janOsch··on Theheadless.dev – open source Puppeteer and Playwright knowledge base
I am asking out of curiosity: is it possible & legal to set up a simple proxy server to redirect analytics data to the provider? So that the analytics traffic goes to the same domain - and is not blocked?

This list gives me shivers...is the USA a scary, uncivilized country?
janOsch··on Top Mistakes and Learnings from My Startup: Postmortem Samsamia
It seems that this startup was successful in finding product market fit but was killed because of co-founders mismatch.

I am planning to start a business with my fiancée, we have been together for 10 years, and we complement each other nicely in terms of skills. What are your experiences with that?
