From home temperature monitoring to a Kubernetes cluster hosting a live Drupal website, I have a lot of experience running Raspberry Pis. I've used every model through the years, and am currently using a mix of A+, 2 model B, and 4 model B Pis. The 3 model B+ was the first generation that had me concerned more about…
A few minutes ago I came across a Hacker News post that detailed a method of adding search to your static site. As you probably know, adding search to a static site is a bit tricky, because you can’t just send the query to a server and have the server process it and return the results. If you want full-text search…
Sounds great! But what does it mean? seL4 seL4 (pronounced ess-e-ell-four) is arguably the world’s most secure operating system (OS) kernel. The OS kernel is the lowest level of software runn…

A recent trend in our industry is the software architecture move from a monolith app to microservices, often with a related blog post explaining how much better everything is after. A recent blog post by neo-bank Monzo explains that they have reached the crazy amount of 1500 microservices (a ratio of ~10 microservices…
You’ve likely heard everyone at the office or online proclaim that “K8s has eaten everyone’s lunch!” or that “everything should be in a docker container!”. While there are advantages to the above methodologies; it’s very easy to have cargo-culted their adoption; especially for Kubernetes (K8s). I find the biggest…
Some examples of using unix tools in a pipeline
I’ve been thinking about cross platform GUIs, and one question led to the next and eventually I was asking: how do pixels end up on the monitor? A pretty neat stack overflow response answers:
It is well known that Win9x variants prior to Windows 98 have a tendency to crash on fast CPUs. The definition of “fast” is of course fuzzy but the problems were known to occur on AMD K6-2 processors running at 350 MHz or faster as early as 1998. This led to some acrimony when Microsoft attempted to charge $35 for the…
A lot of people seem to think that distributed tracing isn't useful, or at least not without extreme effort that isn't worth it for companies smaller than FB. For example, here are a couple of public conversations that sound like a number of private conversations I've had. Sure, there's value somewhere, but it costs…
Google Fonts is fast. Now it’s faster. Much faster.
Taking a second look at the newly introduced mask registers, this time with the benefit of a SKX die shot from Fritzchens Fritz.
I got into some interesting discussions about IPv6 on Twitter. Then someone asked if Android is getting DHCPv6 support in version 11 of the OS.
I've just released a new version of Idris 2 , which is a significant release in that it's the first one which is able to compile itself. Thus, it's the first one where we can really see how the performance of Idris 2 improves on the performance of Idris 1.
Using setjmp(), longjmp(), and assembly to implement a simple threading system in C!
I sense this sentiment on the internet that RAID is dangerous, that the likelihood of your RAID array failing during a rebuild is almost a certainty, because hard drives have become so large.
NetNewsWire is fast because performance is one of our core values. Being fast is part of the very definition of the app.
Decimating Array.Sort with AVX2. I ended up going down the rabbit hole re-implementing array sorting with AVX2 intrinsics. There’s no reason I should go down alone.
There are two types of engineers, the ones that can quickly do estimates and the ones that can’t. Are these people just smarter, or is there more to it? Enrico Fermi was a master at estimation Back of the envelope estimation is a skill that can be learned with practice. It becomes easier once you get familiar with…
In episode 379 of ATP both Marco Arment and John Siracusa described noticeable delays and stalls after upgrading to macOS 10.15.
A few weeks back, I was at XDC and gave a talk about various current and past input stack developments (well, a subset thereof anyway). On...
Trying to figure out how KVM-based virtual machine hosts work by implementing one from scratch.
I have a particular view of Python performance from my experience on the Pyston project, and since this view is somewhat nonstandard I wanted to take some time to explain it and give a motivating e…
Hopefully some signal in the noise.
T The problem Every once in a while I get involuntarily dragged into heat...
