I’ve long since been a die-hard BeOS fan and have been running the open-source recreation Haiku for many years. I think it’s interesting to explore the “alternative OS” world and consider some great ideas that for whatever reason never caught on elsewhere. The way Haiku handles package management and its alternative…
When you generate an SSH key (like I did when looking at signing commits with SSH keys ), you get a “randomart image” from ssh-keygen . These things:
In which you probably wonder, but ...why?
Since declaring our intention to leave the cloud in October, we've been busy at work making it so. After a brief detour down a blind alley with an enterprise Kubernetes provider, we found our stride building our own tools, and successfully moved the first small application out of the cloud a few weeks ago. Now our…

What is a LAN? What is a network segment? How are L1, L2, and L3 segments related? What does it take to send an IP packet from one host to another? What is the difference between LAN, VLAN, and VXLAN?
One of the best features of Podman is how well it works with systemd. Podman uses the standard fork/exec model, which is easily adaptable to the systemd syst...
There is more to communication than just the correct use of words, phrases, and clauses. Let’s look at some of the communication skills that don’t get enough attention.
A common assumption I see on the ‘net is that NP-complete problems are impossible to solve. I recently read that dependency management in Python is hard because package resolution is NP-complete. This is true in principle, but the reality is more complicated. When we say “NP-complete is hard” we’re talking about…
This week I stepped out of one world and landed in another. It started while I was marking assignments in a few of my programming courses.The quality of the code I was reading was amazing! My students were doing the sorts of things that my open source peers do:
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…
This is my opinionated list of four approaches to building websites and web applications. Publicly hosted on the internet, serving HTML, CSS, JavaScript, images, etc over HTTP.
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.
Technical excellence begins in wonder but is honed by disgust
(Spoiler alert: it has been very successful, but there are some lessons to be learned)
It’s Saturday, and I’m enjoying the last sunlight for the day in my studio. The house is silent now; my family is taking a nap downstairs. And I’m here, writing, in silence. There’s a thought that kept coming in the last few weeks. As painful as it is, any creation happens in isolation without any signals or external…
A practical guide to starting a personal blog you can keep for years, without depending on social platforms or fragile tools.
I found myself going down a previously unexplored rabbit hole recently, or more specifically, what I thought was "a" rabbit hole but in actual fact was an ever-expanding series of them that led me to what I refer to in the title of this post as "6 rabbits deep"
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 woke up yesterday to the news that DigitalOcean has cut a bunch of jobs from the payroll. It sounds like a pretty big wave, and yes, my job was lopped off
The recent Ohio train derailment and subsequent fire that released vinyl chloride into the environment has been a terrifying experience for the nearby population. The accident rekindles memories of the 1979 train accident in Mississauga, Ontario, when over 200,000 people had to be evacuated after a wheel bearing…

Once you become an engineering executive, an invisible timer starts ticking in the background. Tick tick tick. At some point that timer will go off, at which point someone will rush up to you demanding an engineering strategy. It won’t be clear what they mean, but they will want it, really, really badly. If we just…
