I’m leaving Datadog at the end of next month and plan to spend some time on personal projects, I’ll probably look at finding another job next September.

17-year-long Scottish study of 82,000+ adults finds commuting by bike reduces your risk of:
• early death
• hospitalisation for any reason
• cardiovascular disease
• cancer mortality
• treatment for mental health problems.
Yeah, but those LTNs and bike lanes are *really* annoying.

Real professionals do not plug random devices into their computers. Real professionals do "curl -sL totally-trustworthy-site.com/install.sh | sudo bash" instead.

It was really nice to see my work used to reduce latency of complex event recognition queries by an order of magnitude in a paper in ACM, but I was disappointed to find I hadn’t been cited, hopefully this will be fixed.

TIL when you use "from module import function" python still loads the entire module. Saw this in my memory flame graph. I moved some functions with heavy deps to a separate file and it deleted a whole "flame" of memory allocations

If you are eager to write something you are going to regret (if you are lucky, also be proud of) in 10 years, want to tinker with Kotlin and not afraid of dragons (also: performance, concurrency), drop me a line!

I want my experience of this app to be apolitical, but everyone I follow gets three strikes: if I see one dimensional political takes three times because of you, I stop engaging with you on any other topic. I hope this will keep my timeline readable.

Even more important than having colleagues which give you kudos for a job well done, is to have peers who tell you in a constructive and encouraging way if there's room for improvement in what you do. It's hard to get any better without this sort of feedback.

Parts of Leyden and other CDS improvements are now in JDK mainline, in time for JDK 24 fork. The improvements are visible even on simple HelloWorld-style examples. There are even more things to squeeze!

range queries (e.g. `age > 20 AND age < 35`) have a cool indexing strategy in apache pinot. each row gets assigned to `log(n)` bitsets based on the binary representation of `age`. range queries then turn into unions and intersections of these sets.

RangeBitmap - How range indexes work in Apache Pinot
Suppose you have an unsorted array of numeric values and need to find the set of indexes of all the values which are within a range. The range predicate will be evaluated many times, so any time spent...

If you enjoy programming, as opposed to software engineering in the large, I expect codebases where unique semantics are preserved as cross-cutting concerns to be the last refuge from LLM automation. Working on OpenJDK is probably a pretty safe bet.

Hi, I'm Claes.
I grew tired of that other place, too.
I work mostly on the OpenJDK (github.com/cl4es). Sometimes I blog a bit about that (cl4es.github.io), though it's been a quiet lately because reasons.
Here to look for inspiration and engage with others.

This is nice, but the reality is running a social network with millions of users is a costly business, and donations are an ineffective funding mechanism. Cue advertising revenue, product managers with engagement targets, algorithms designed to enrage. Enjoy it while it lasts.

I haven’t seen a starter pack where I don’t recognise some of the members by their spam from Twitter, so I’m not going to use any. Unless there are really good starter packs out there?

Who should I be following here for JVM, data, performance topics? I enjoyed the lack of politics in my first scroll here, I think I’m going to enforce that with my follows as I start using the app more.
