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…

Comparing Svelte and React
Last year I created Pomodone , a small time tracking application based on the Pomodoro technique of working in 25 minute intervals. It's a pretty basic app; it has a 25 minute timer (that runs in a Web Worker) and saves a history of your "poms" to a small Firebase database. I initially built it using React (well…

Crazy fast build times, or when 10 seconds starts to make you nervous (2012)
Firstly this is not just my effort but my team and organisation. Secondly the usual rules apply, this is expert advise and what works for me will very probably cause your whole production stack to blow up and kill people. Lastly this is long so skip to the bit you care about or come along and chat at QCon London 2012

GPT-3 tries pickup lines
Once upon a time I decided to train a neural net to generate pickup lines. Once I started collecting the training data I began to regret it when I saw how awful the existing lines were. Turns out I needn’t have worried. The neural net I used was so small and clueless that

Closing web browser windows doesn't close connections
Months ago I noticed something strange in the Little Snitch Network Monitor: Safari was still connecting to web sites after every window had been closed.

The Raspberry Pi can boot off NVMe SSDs now
When the Compute Module 4 was released (see my CM4 review here), I asked the Pi Foundation engineers when we might be able to boot off NVMe storage, since it was trivially easy to use with the exposed PCIe x1 lane on the CM4 IO Board. The initial response in October 2020 was "we'll see". Luckily, after more people…

Living Like It's 99, No Social Media, No Smartphone
I’ve now lived without social media and without a smartphone for the past 3 years. And I’m still alive. A lot of people have asked me how I made it. So I wrote an article about it. The why, the how, and the now.

Automatic Video Editing
