One of the advantages of of protobuf I never see anyone highlight is how neat and well-designed the wireformat is, in terms of backward/forward compatibility and lowlevel stuff you…

This brings back memories debugging an azul zing bug where an effectively final optimization ended up doing the wrong thing with zstd-jni. It was painful enough that I couldn’t con…

I agree. It’s the enshittification of the internet. Luckily we still have infrastructure providers with more sensible offerings. We don’t have to use aws, gcp, etc.

I've used bazel for about 10 years, all in small orgs. Right now, single digit team. I don't think there exists a better solution for a project mixing Java and C/C++ than Bazel. Th…

That’s the default in the monorepos I’ve worked on. When a third party dep is broken or needs a workaround, just include a patch in the build (or fork). Then those patches can be u…

I enjoyed both talks a lot. I really appreciate the work done to evolve Java. They seem to be able to both fix earlier mistakes (and there were many!) and new ones from happening. …

I think the «best practices» found in Java enterprise has meant that a lot of people think all Java has to look like that. High performance Java is awesome and can be competitive w…

Mechanisms for getting the linux kernel out of the way is pretty decent these days, and CPUs with a lot of cores are common. That means you can isolate a bunch of cores and pin thr…

Isolating a core and then pinning a single thread is the way to go to get both low latency and high throughput, sacrificing efficiency. This works fine on Linux, and common approac…

In a previous project we used fixedint32/64 instead of varint values in the schema for messages where performance was critical. That left only varint used for tags. For encoding we…

Nice work! I love the care and discussion around low level optimizations, as such things are often ignored. There are a lot of interesting variants of rank/select and other succinc…

The number of unique int32 values is not that great, and a full bitset would only be 512MB. Hard to bit a dense bitset in performance. As a general purpose data structure, I would …

Selective testing is great also for smaller projects to help keep velocity high for merging and working with branches with many commits. I implemented selective testing using bazel…

I'm a big fan of this solution! It's always been annoying to perform all the ceremony involved in deploying a system with a bunch of files, with config, scripts and system written …

I always found the existing bazel integrations annoying. My solution has been to generate .classpath based on a set of bazel queries. Not what's officially recommended, but it has …

There's a lot of ceremony to run jdtls! I find it easier to just install language servers using brew. Then the command can be simplified to cmd = { 'jdtls', '-data', home_dir .. '/…

They could also have gone the commercial route and gotten Zing with their pauseless GC. It’s been around forever and they even cover Cassandra in their marketing. https://www.azul.…

Patch series comes from the linux kernel workflow, which git was developed to support. https://kernelnewbies.org/PatchSeries In this workflow you review every commit and not just t…

The use case is when you look at a branch as a series of patches. Reviewing a clean set of commits is much easier than a branch full of mistakes and wrong paths taken. Useful when …

I struggle to use lmdb when using resource isolation (like docker, nomad exec driver). The hidden complexities really become apparent when you build largish systems using shared in…

I was asking around in my network after experience with self hosting S3 like solutions. One serious user of SeaweedFS recommended looking into min.io instead. Another serious user …

There are some workarounds. In my company we have a script that generated IDE files automatically. It uses `bazel query` and `bazel build` to find all external and non native depen…

I have fond memories of my grandfather serving RC Cola to me in a small town in Norway 30 years ago. Imported to the town by a small independent shop focusing on cheaper alternativ…

The lack of “interface” was one of the main reasons I never ended up using scheme to build production systems. I loved playing with scheme in my university days 20 years ago, and l…

We use gitlab and review a commit at a time and do CI runs on each commit in the MR branch. Just plain git with the fixup/interactive rebase dance. Gitlab is not optimized for this…
