Hello from Ares!

I am pleased to be writing today’s blog post from a laptop running Ares OS. I am writing into an ed(1) session, on a file on an ext4 filesystem on its hard drive. That’s pretty cool! It seems that a lot of interesting stuff has happened since I gave that talk on Helios at FOSDEM in February.

The talk I gave at FOSDEM was no doubt impressive, but it was a bit of a party trick. The system was running on a Raspberry Pi with one process which included both the slide deck as a series of raster images baked into the ELF file, as well as...

What's everyone's daily driver device?

Could be anything, from a laptop, to a desktop, to a tablet. I personally daily drive a MacBook Air M1.

I'd noticed that updates to vim's git repository has recently been more sporadic than usual. Now I know why and I'm even sadder.

The rc shell and its excellent handling of whitespace

This blog post is a response to Mark Dominus’ “The shell and its crappy handling of whitespace”.

I’ve been working on a shell for Unix-like systems called rc, which draws heavily from the Plan 9 shell of the same name. When I saw Mark’s post about the perils of whitespace in POSIX shells (or derived shells, like bash), I thought it prudent to see if any of the problems he outlines are present in the shell I’m working on myself. Good news: they aren’t!

Let’s go over each of his examples. First he provides the following example:

for i in *.jpg; do
	cp $i /tmp
done

This breaks if there...

Alpine Linux does not make the news

My Linux distribution of choice for several years has been Alpine Linux. It’s a small, efficient distribution which ships a number of tools I appreciate for their simplicity, such as musl libc. It has a very nice package manager, apk, which is fast and maintainable. The development community is professional and focuses on diligent maintenance of the distribution and little else. Over the years I have used it, very little of note has happened.

I run Alpine in every context; on my workstation and my laptops but also on production servers, on bare-metal and in virtual machines, on my RISC-V and ARM development boards, at times on my...

Организуем фестиваль для хакеров

Дорогой Хабр, сегодня я пиарюсь. Я хочу анонсировать фестиваль под названием "Undefined". Моя задача - завлечь посетителей, показать, как устроен фестиваль изнутри, с точки зрения админа, а также попробовать найти спонсора.

Если коротко, Undefined - это конкурс компьютерного искусства (т. н. демосцены), конференция, хардварный хакатон, выставка самодельной электроники и робототехники (в том числе, ламповой и электромеханической) от частных коллекционеров, музей ретро-компьютеров и приставок. Фестиваль носит неофициальный характер и делает акцент на самодельные приспособления (от английского DIY, или Do It Yourself).

Чтобы статья не была пустой, я расскажу, как управлять гигантскими часами-табло с помощью микроконтроллера, либо Raspberry Pi.

Seriously, don't sign a CLA

SourceGraph is making their product closed source, abandoning the Apache 2.0 license it was originally distributed under, so once again we convene in the ritual condemnation we offer to commercial products that piss in the pool of open source. Invoking Bryan Cantrill once more:

A contributor license agreement, or CLA, usually (but not always) includes an important clause: a copyright assignment. These agreements are provided by upstream maintainers to contributors to open source software projects, and they demand a signature before the contributor’s work is incorporated into the upstream project. The copyright assignment clause that is usually included serves to offer the upstream maintainers...
