All The News Is Gone And The Sky Is Grey Edition
- I didn't post yesterday's update until this morning and now there's no news for today. Oh well.
- A few more notes on the RTX 3090 and GDDR6X. (Tom's Hardware)
It will be the first card to deliver 1TB per second of bandwidth without using HBM. A 384-bit bus and 21Gbps signalling makes for 1008GBps.
The card will come with 12GB of RAM in 12 8Gbit chips. Micron will ship 16Gbit GDDR6X parts next year with speeds up to 24Gbps.
- Writing your own virtual machine. (GitHub)
As in, writing a virtual microprocessor, rather than the container kind of virtual machine.
This is a pretty easy task if (a) you don't need to deliver perfect compatibility with an existing processor and (b) you're not aiming for ultimate performance.
I wrote a simple VM in C++ a couple of years back and got it to nudge 1 TFLOPS single-threaded on a 2015 iMac without any clever tricks. That was when I was still looking at writing my own programming language, before Crystal came along and filled that niche.
If I do it again, first I'd probably write it in Crystal (it's nearly as fast as C and much nicer to user), and second I'd do it as a virtual fantasy retro-computer, a 10-bit or 12-bit home computer that never was.
Put it into a tiny Linux distro, plop the whole thing on a Chuwi Larkbox, and you have your very own retrocomputer without ever having picked up a soldering iron.
- Ubuntu 18.04.5 LTS now includes the Linux 5.4 LTS kernel from Ubuntu 20.04 LTS. (9to5Linux)
I guess LTS stands for long-term support and not long-term stable. RedHat back-ports bugfixes and security patches to older kernels while maintaining 100% compatibility; Ubuntu seems to just keeping the user space the same.
- Fun fact: Semi-automatic rifles with large (20 round) magazines were first invented in the Holy Roman Empire.
- Twitter seems to have hired Clippy to enforce self-censorship.
In case Twitter is misbehaving:
Music Not Really A Video of the Day
It's a great album. Also contains... Oh, there's a cleaner version of the Alive and Brilliant video available now.
And Today I'm a Daisy.
Actually, not sure if those will work for everyone. It not only shows up as YouTube Premium (which I have because of that Google Play Very Long Name subscription), but worse, YouTube Premium Australia.
