We’ve written previously about the fact that the Internet seems to be missing a standard protocol for the request/response paradigm, with repeated attempts to force-fit TCP leading to inevitable mismatches. Sometimes we feel that we are the only people who think this way, with our networking
One of my readers asked for my opinion about the provocative “It’s Time to Replace TCP in the Datacenter” article by prof. John Ousterhout. I started reading it, found too many things that didn’t make sense, and decided to ignore it as another attempt of a proverbial physicist solving hard problems in someone else’s…
Since the change of year, I’ve been using Alpine Linux on my main computing device (a new desktop PC that I assembled in December). These are some notes on in, some niceties and caveats.
Yes, here at Old VCR we live in the past, when RISC Unix workstations still ruled the earth like large boxy tentaculous Cthulhus. Oh, sure, ...
I’ve been writing a pubsub listener for work recently and had this silly “shower thought”: the ideal queue should be empty. Why? If the queue is not empty, it means that whatever job is consuming from the queue is not keeping up with messages coming into it. Ok, then if queues are supposed to be empty, then what are…
Tailscale v1.36 for macOS features a significantly reduced binary size (going from 92MB to 56MB). The effort started out with a chance observation about a surprisingly large executable, and ended up involving some creative approaches using dlopen.
This post will mainly focus on ROCm HIP wasted opportunities for adoption. I wrote an overview of ROCm earlier at https://threedots.ovh/blog/2021/11/what-is-amd-rocm/ . This post will specifically eschew talking about issues about the API renames in ROCm HIP – breaking source compatibility with CUDA quite needlessly.
To be able to investigate and work on the the measured boot features I have switched from grub to systemd-boot (sd-boot).
Go inside the WAL file with this in-depth look at WAL file Log Sequence Number (LSN), WAL segment positions, WAL file names, and pg_switch_wal.

On this Valentine's Day Weekend I share the heartbreak that caused my fear of commitment to the 1st CPU Core of any socket (not just core 0).

Today, the Manticore team is thrilled to announce the release of Manticore Search 6.
Service mesh is a blazing hot topic in software engineering right now and rightfully so. I think it’s extremely promising technology and I’d love to see it widely adopted (in cases where it truly makes sense). Yet it remains shrouded in mystery for many people and even those who are familiar with it have trouble…

Command languages and scripting languages are and should be different things.
podman provides an integrated auto-update mechanism, which I recently applied to all of my containers running on feldspaten. The mechanism is nice, but at first appears a bit counter-intuitive. In this post ’m trying to explain how you can use the mechanism and what to watch out for. I’ll start with the trap I think…
This is a brief mini-howto on how to build a linux based wireless router out of what amounts to spare parts, using the linux router project's single disk router software. The total cost of each end of the router, including antennas and cabling, is less than 1300 US dollars, which is a considerable cost savings over…
A deep dive into container scheduling and Flyd, our new orchestrator.
Audio formats typically fall into one of three categories: “lossless” , “complicated” or “bad” . After developing a simple image format last year, I tried to come up with an audio format that fits neither of these categories.
