Recently I was doing some work decoding the new Galileo High Accuracy Service data. In short, this new service will allow Galileo (“European GPS”) users to achieve decimeter-level accuracy, which is nice. This “HAS” data is transmitted highly redundantly by making good use of Reed-Solomon encoding. To work with this…
How to keep secret credentials safe on the command line.
So it’s borderline useless for all but the simplest use cases, and even there it does a very subpar job. I’d like to have an inline image every now and then, or organize things in some multi-column layouts or the like, or a table. 19th century newspapers could do this, and if your technology can’t emulate typography…
Just now, Avdi had a miserable experience buying curtains. He went to pick up an order that he placed last night, but Lowe’s didn’t have it. The order was sent to the wrong store and it…
I want to say a few words about my current adventure. I joined the Fuchsia project at its inception and worked on the daunting task of buil...
Physicists have proved that a subatomic particle can switch into its antiparticle alter-ego and back again, in a new discovery revealed today. An extraordinarily precise measurement made by Oxford researchers using the LHCb experiment at CERN has provided the first evidence that charm mesons can change into their…

I was 9 years old. A revision of the notebook containing my first Z80 assembly language program
A while back there was a thread on one of our company mailing lists about SSH quoting, and I posted a long answer to it. Since then a few people have asked me questions that caused me to reach for it, so I thought it might be helpful if I …
It's a common architecture to have PostgreSQL and Redis serve as the backbone of your app, but PostgreSQL may be capable of everything you use Redis for.
Learn about Taildrop, the first test of an experimental p2p app discovery layer in Tailscale. Understand why it was so easy to build, and how it works for large files.
This talk will reflect on what GNU Guix has to offer to users and how it compares to other approaches—from CONDA and pip to Flatpak and Docker. Guix is not only a transactional package manager and declarative GNU/Linux distribution: it’s also an environment manager, a container provisioning tool, and more. We will…
In order to support its growing ecosystem and community as we move toward the 3.0 release, we are making changes to Vagrant that will maintain its Ruby-based features while being ported to Go.
I find word etymologies fascinating . Every word we speak or write sits unassumingly on the surface of a rich history, sometimes spanning millenia.
When it comes to accuracy, how you add a series of arbitrary values together, and average them still matters.

Who were the Romans? How did they understand themselves as a people and ‘Roman’ as an identity? And what were the implications of that understanding – and perhaps more importantly…
Software is full of circular dependencies if you look deep enough. Compilers written in the language they compile are the most obvious example, but not the only one. To compile a kernel, you need a running kernel. Linkers, build systems, shells. Even text editors, if you want to write the code instead of just…
In this article, the author shares their experience as an engineering manager and the challenges they faced when trying to reach alignment and prev...
How to use aligned word vectors from fastText to translate words from one language to another instantly.
The goal is to connect a non-WiFi computer to a WiFi network using a Raspberry Pi. We will use a Raspberry Pi 4 Model B as a bridge between the non-WiFi computer and the WiFi network. The Raspberry Pi connects to WiFi and shares its connection with other computers over Ethernet. These instructions were only tested and…
In a previous post, I wrote about a new set of technologies “Privacy Preserving Advertising”, which are intended to allow for advertising without compr

Since 2008, I've ripped every DVD and Blu-Ray I bought to my Mac, with a collection of SD and HD media totaling around 2 TB today. To make that library accessible, I've always used iTunes and the iTunes Shared Library functionality that—while it still exists today—seems to be on life support, in kind of a "we still…
