Friends are coming over for (distant) bday fun but I've pushed a bunch of updates to the #Spritely site:

Only two subsystems left to describe...!

Thinking out loud ...

People are saying the mortality rate of COVID-19 is ~ 1%. Roughly the number of cases trebles every 5 days, or roughly by 10 every 10 days.

Time from infection to death is ~3 weeks, say 20 days.

So ...

In the UK there've been 10 deaths. At 1%, that means 1000 people had the virus 20 days ago. It's multiplied by 10 twice since then. On that basis ...

The current number of infected people in the UK right now, detected & undetected, is ~ 100K.


It seems a lot of people are finding out about now that their team has transitioned to remote work. Coincidentally, we've been working on a major upgrade to our encrypted kanban app featuring a markdown editor and tagging system for all your tasks. #WFH

Very pleased to have stumbled across org-roam (

I think it'll be the next step I wanted for my personal wiki that I've been keeping in org-mode.  I tried org-brain for a bit (again) and it just didn't click, and also broke my org-publish step.  org-roam just works with straight up org file links, nothin' fancy needed.

Hoping it'll get me a bit closer to TiddlyWiki in Emacs kind of thing that I'm after.

even mediocre programmers can write a program that RUNS. what distinguishes a skilled programmer isn't how well they talk to the machine, it's how well they talk to the other people who will read/write/use the code

The fastest way to get your favorite Twitter user to join the Fediverse is simply to ask them for a link to their account on the Fediverse so you can follow them!

It's as simple as that.

The more people that ask journalists and other professionals to provide them with their link to their Fediverse profile, the more people will sign up and create one. #fediverse #twitter #exodus #mastodon #pleroma

The latest in my series of case histories of #AdversarialInteroperability and the role it played in keeping tech competitive is the history of Gopher, which I was able to write thanks to the generous assistance of Gopher's co-inventor
