Lessons learned after working one year as a Common Lisp Developer (2018)
I intented this to be a small post with some lessons learned after working one year as a CL dev, however it turned out quite long (two parts!). As always: All opinions are my own. This post is not endorsed by anybody.

Raspberry Pi KVMs Compared: TinyPilot and Pi-KVM v3
In a strange coincidence, the authors of TinyPilot and Pi-KVM both emailed me within a week of each other and asked if I'd be interested in one of their KVM devices. Michael Lynch, founder of Tiny Pilot, said he'd used some of my Ansible work in building the TinyPilot update system, and Maxim Devaev, of Pi-KVM, liked…

Google could have killed Facebook with the flick of a switch
As we near the end of this decade, and more importantly the end of the hell that was 2020, I realised two things. First, I survived catching Covid-19, and secondly that I had a good story about the…

Counting cycles and instructions on the Apple M1 processor
When benchmarking software, we often start by measuring the time elapsed. If you are benchmarking data bandwidth or latency, it is the right measure. However, if you are benchmarking computational tasks where you avoid disk and network accesses and where you only access a few pages of memory, then the time elapsed is…

Why do drum sets have descending toms?
Before mic’ing became a necessity, acoustic drums were just that: acoustic. And when they needed to be louder, drum manufacturers made them bigger and longer. That led to some diameter and de…

Chiptunes on an ATtiny4 and the 3 Cent Micro
Ever since hearing about Rob Miles' Bitshift Variations in C Minor , a 4-voice polyphonic 16 minute piece of algorithmically generated music, I wanted to implement it in hardware. Getting it onto just any microcontroller seemed too easy , so I wanted it to run on the smallest µC I could find — the ATtiny4. A while…

The Rise of One-Time Password Interception Bots
In February, KrebsOnSecurity wrote about a novel cybercrime service that helped attackers intercept the one-time passwords (OTPs) that many websites require as a second authentication factor in addition to passwords. That service quickly went offline, but new research reveals a number of competitors have since…

Generics facilitators in Go
Go 1.18 is going to be released with generics support . Adding generics to Go was a multi-year effort and was a difficult one. Go type system is not a traditional type system and it was not possible just to bring an existing generics implementation from other language and be done. The current proposal was accepted…

Quick and dirty way to rip an eBook from Android
I recently purchased a book for my MSC which was only available via a crappy Android app. There was no obvious way to decrypt it to read on a more sensible device, so I resorted to the ancient art of screenscraping. This is a quick-and-dirty way to grab images of the pages and convert them to a standard PDF using…

Kina Knowledge, using Common Lisp extensively in their document processing stack
Recently, the awesome-lisp-companies list was posted on HN, more people got to know it (look, this list is fan-cooked and we add companies when we learn about one, often by chance, don’t assume it’s anything “official” or exhaustive), and Alex Nygren informed us that his company Kina Knowledge…

s/bash/zsh/g
There is simply no way you can do calculations with fractions in bash without relying on bc , dc , or some hacks. Compared to simply being able to use a + b it’s ugly, slow, and difficult.

Quitting a New Job
Two years ago, I did something that I’d never done in my career before- I left a job (at Nuro) only a few months after starting it. In this post, I want to explain what happened and what I learned from the experience.
