Given $$M, N$$, matrices, let
$m_{ij} = \lfloor \log_2 M_{ij} \rfloor$
and similarly for $$n$$. Then $$M_{ij} \approx 2^{m_{ij}}$$. Define $$m \star n$$ by
$(m \star n)_{ij} = \max_k (m_{ik} + n_{kj}),$
This gives us an approximation $$(M \cdot N)_{ij}\approx 2^{(m \star n)_{ij}}$$

Has anyone here encountered this before? It's essentially floating point matrix multiplication without the mantissa bits, but I'm wondering if there are any papers or resources dealing with it.

I say "essentially", but I just mean "similar to"

‪after 4.69 years of uptime and over 16 years of continuous service our very last 64 bit DEC Alpha retired itself early this morning. @netbsd #bsd #rip #thankyou #goodbye

Mmmmmm try fucking off.

Apparently , instead of deleting files like I asked it to, has been moving everything to ~/.local/share/Trash/files. Ugh, I moved to and to get away from this shite.

Why do I have so many mini-usb cables and barely any micro? I can't even remember the last device I bought that required mini-usb

The #gameoftrees FAQ summarizes our responses to several questions the internet was asking when the project first became known to the general public: gameoftrees.org/faq.html

I friggin' love this educational video.

It's a -era film explaining . I listen to it over and over to practice my Russian. Repetition and a familiar subject help a lot.

Also, it's out of copyright. Soviet films belong to the people, comrade.

#Ghidra might be one of the coolest things I've played with lately, kind of bizarre seeing it running on #OpenBSD. The decompiler tool is.. something else. Also, notice RETGUARD prologue/epilogue?

On -current:
$pkg_add ghidra$ ghidraRun

Running NSA reverse engineering tool on the Huawei matebook, of course. 😏

Why did I tidy? Now I can't find the tip of my soldering iron.

I have no recollection whatsoever of the last 6 pages I read.

Looking for undeadly.org staff contact :)

I digged up 13 #OpenBSD developer interviews in manageable format that we did for the 20th project anniversary.

It would be great if undeadly.org was willing to re-publish them (currently there is only undeadly.org/cgi?action=articl pointing at dead links)

Not a fan of these, but this one certainly has it's charm:

I finally got my Minecraft account back after months, and all I am thinking is

DRM is bullshit and we should all just be investing in Minetest instead 😕
