Foldable Words
Packing up the household for a recent move, I was delving into shoeboxes, photo albums, and file folders that had not been opened in decades. One of my discoveries, found in an envelope at the back of a file drawer, was the paper sleeve from a drinking straw, imprinted with a saccharine message:

Let's take take a look, using the disastrously bad unix libc timezone tools , which you're almost certainly using under the hood if you're…

Amazon competitor got our belt listing taken down by saying it contains drugs

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…

Turtle visual cortex is non-retinotopic

Turning an old Amazon Kindle into a eInk development platform

Starting Over: A FOSS proposal for a new type of OS for a new type of computer
My talk should be on in about an hour and a half from when I post this. A possible next evolutionary step for computers is persistent memory: large capacity non-volatile main memory. With a few terabytes of nonvolatile RAM, who needs an SSD any more? I will sketch out a proposal for how to…

Migrate Everything from Linux to BSD
As an operating system GNU/Linux has become a mess because of the fragmented nature of the project, the bloatware in the kernel, but mainly because of the manipulation by corporate interests. There exist several technical reasons for when a migration from GNU/Linux to BSD make sense, but this article isn't about that…

Change your MAC address with a shell script (2019)
Sometimes I'm at a coffee shop and get locked out of the wifi, after an hour or two has passed. Rather than spending 2 minutes/week entering terminal commands, I thought it made sense to spend a few hours figuring out how to make it take one minute a week, instead, via AUTOMATION

How to Kill a Unicorn
I took a deep dive on freemium pricing and decided to document it in this post. Why freemium? I think it’s how the little guys can win against market leaders. Basically, it’s how you kill a unicorn. Notion, Figma, Canva, Mailchimp, and Segment. What do all of these
