Help needed to build a lookup tables

Hey everyone, I need an Argon2id hash lookup table for a project I'm working on.
The thing is, I need A LOT of them (the final final must be around 2/3Gib).
I did the math, that's ~20,000,000 hashes. Considering that my computer is old, and argon2id was literally made for this to be slow, it would take me more than 2 months computing hashes 24/7 to get this up. And I can't run my computer 24/7…
So I need you help, fellow CPU burners :)
If you would like to help me out, grab the code and join the hash party !
Code:git clone git://git.z3bra.org/hashcrush.git

mDNS Primer

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.
