erikvanoostenon Precursor

Your keyboard and mouse rhythm and timings are probably so unique that they can be considered PII. Wonder how that works out legally.

erikvanoostenon Jolla Phone (October 2026)

Perhaps my bank is special (Triodos), its app works just fine on the Jolla.

erikvanoostenon Capture Checking in Scala

Scala (with ZIO) is still the only language I know that lets me write a fairly complex program with a few unit tests, and then run it without any bugs.

erikvanoostenon How to Firefox

Open a new tab for a certain container with Cmd-1 (or Cmd-Shift-1, I forgot) for the first container in your list, with 2 for the second, etc.

erikvanoostenon Aeron: Efficient reliable UDP unicast, UDP multicast, and IPC message transport

It has been a while since I saw their presentation. What I remember is that Aaron has an insanely low delay even in the high percentiles, that is orders of magnitude better. Throughput for a large stream of data is probably similar to plain UDP. Please correct me if I remember wrong.

erikvanoostenon Aeron: Efficient reliable UDP unicast, UDP multicast, and IPC message transport

With Aaron I would think the focus should be on 'efficiënt', not reliable. Within a datacenter they are orders of magnitude faster than plan UDP. You get this crazy efficiency at the cost of reduced flexibility in how you send messages.

erikvanoostenon The Fastest Way yet to Color Graphs

Indeed. Thanks, I stand corrected.

erikvanoostenon The Fastest Way yet to Color Graphs

You can convert edge coloring problems into vertex coloring problems and vice versa through a simple O(n) procedure.

erikvanoostenon Nvidia's Project Digits is a 'personal AI supercomputer'

> It’s a cloud computing platform that sits on your desk …

This goes against every definition of cloud that I know off. Again proving that 'cloud' means whatever you want it to mean.

erikvanoostenon The Hexagonal Tiling Honeycomb

I wonder how this compares to H3. Why does H3 has pentagons as well, and this doesn't?

erikvanoostenon Zio-Kafka, faster than Java-Kafka

TlDR: Concurrency and pre-fetching gives zio-kafka a higher consumer throughput than the default java Kafka client for most workloads.

erikvanoostenon Care Doesn't Scale

Another non scaling field is making houses ready for the energy transition. Here in the Netherlands there is a lot of uncertainty and distrust which requires an almost one-on-one approach for each (owned) house. Only powerful neighborhood initiatives can do this and do well.

erikvanoostenon Study: Air purifier use at daycare centres cut kids' sick days by a third (2023)

You don't need poor schools for that. Just ~3 years ago exactly this happened to a public primary school in a rich neighborhood of Haarlem (The Netherlands). If I remember correctly, the filters had not been replaced for 8 years.

erikvanoostenon MavenGate gets it all wrong and hurts open source

As package maintainer you are required to sign the packages with a PGP key. Maven Central also requires that you upload that PGP key (the public part only of course) to one of a few well-known key servers.
