Datalagring, igen!
Some of my usual readers will have to excuse me. This post will be in
Swedish. It's about proposed Swedish legislation for forcing someone
who offers a message system to the public to cooperate with the law.

TKey SSH CA
I wrote a stupidly simple SSH certificate authority that can you can
use directly over SSH to buy new certificates. It can be used with a
Tillitis TKey both for the private key of the CA itself and for the
user authentication to get a SSH certificate:

for user authentication, but also solving the problem of public key

The Uniform
[Based on a story I wrote during upper-secondary school based on real
events. I translated it recently from Swedish and edited some of it. I
removed most (all?) elements of fiction.
Not a typical night, since it's at an event in another city, but it
gives a taste of what partying in, say, 1989(?) was like. And yes, I
really usually drank two bottles of wine during a pre-party in those
days. Not unusual in the crowd I was hanging out with, I'm afraid.]

Experiment in Digital minimalism
I recently read Cal Newport's book _Digital Minimalism_. It really
resonated with me, despite (or because of?) being glued to my computer
many hours of the day.
Cal suggests a month of digital decluttering, at first cutting off
everything that your job and other obligations don't depend on. At the
end of the month you evaluate what, if anything, is to be let back
inside.
I did a decluttering plan for April. It ended up being an ongoing
project when I'm writing this in June.

Evening, hackers! I feel a column coming on!
TL;DR: In which we learn about the EU parliament election, some

Security Fest conference, fighting against a Supermicro server, and
some other recent shenanigans,

Dream Setup
I love Daniel Bogan's Uses This blog, even though it seems a bit Apple
heavy at times. People sharing what tools, both hardware and software,
that work for them is very helpful. A lot of things I never knew
about came from this or similar sites, or just people's own home pages
copying Uses This' questions and giving their own answers.

About death
I'm on a train again. This time I'm going home from Hudiksvall after a
grueling weekend.
I went from Malmö on Thursday morning and worked the entire day on
trains. I arrived in Ljusdal after close to nine hours. I checked in
at the only hotel in town again and, after a quick meal and glass of
wine, went over to a very sad dad with a bottle of Macallan. We didn't
empty it but we sure tried. I got back to the hotel pretty late.
Wasn't able to sleep much.
The day after it was my dad's wife's funeral. Met up at dad's ... ⌘ Read more

Presentation at Sundsgymnasiet school
I was invited by Mats, a teacher at the Sundsgymnasiet school in
Vellinge, to give a talk to his students, all three years of the
Technical Programme. Sundsgymnasiet is an upper secondary school,
probably what in the US would be called senior highschool, with
students normally starting in the year they turn 16 and finishing
at 19.
I didn't know what to expect, really. Mats told me I could talk about

Keyboard layouts
I've updated my article about keyboard layouts with XKB after 13
years!
https://hack.org/mc/writings/xkb.html
I've edited it so the focus is on the layouts if you just want to grab
them and don't need any handholding. Also added Thinkpad layouts along
with the original HHKB layouts.
It now also includes instructions for use with the River and Sway
Wayland compositors as well as X11.
I will probably update it soon with some images of different Thinkpad
keyboards. ⌘ Read more

about doing them on the blog instead, but see below for some thoughts

MC in the US: OSFC, SF, Seattle, Microsoft
OSFC badge saying "Speaker" and handwritten by me, "MC".
I attended the [Open Source Firmware Conference (OSFC)](https://osfc.io) on Oct 10-12 in
Sunnyvale, spent a long weekend in San Francisco, took a very long
train ride to Seattle, spent a week in the Seattle area, and held an
intimate talk at Microsoft. Managed to meet friends, drink some nice
beverages, and even see a show but came home with a heavy heart. Then

Tillitis TKey
The Tillitis TKey, which I first wrote about in September last year,
is now available for sale at the the Tillitis webshop.
The TKey is a small bare-bones RISC-V computer in a USB stick form

and derives a deterministic secret every time the same app is started.
You can use it, for instance, as a security token to keep your private
key and do signing operations. Everyt ... ⌘ Read more

Gemini capsule
Gemini is a lightweight Internet protocol. It's heavier than Gopher
but lighter than HTTP(S), especially if combined with all other web
technologies. The name makes sense if Gopher is Project Mercury and
the web is the Apollo program.

Markdown-like markup language, instead of HTML. Gemini browsers don't
