In the early days when the kernel was small (I used to build kernels and copy them to floppy disks, and boot Linux from there) the kernel was called 'vmlinux', and when compression was added after the kernel started to get bigger it became 'vmlinuz'. It was still possible to boot from 'vmlinux', and it may be possible today as well, for all I know.
And 'vmlinux' was inspired by the 'vmunix' (Virtual Memory Unix) the UNIX kernel.
"Nvidia dgx os", ugh. It would be a lot more enticing if that thing could run stock Linux.
DGXOS is a customized Ubuntu Noble!

I couldn't get Nvidia AI Workbench to start on Neon KDE after changing to DISTRIB_ID=Ubuntu in /etc/lsb-release. Neon is based on Ubuntu Noble too.
Thank you, my friend! Let me know when it's done (only so that we can celebrate it together—good faith for the win!).
Just donated $100 to ZSF via ever.org!
Joran from TigerBeetle here!
TigerBeetle actually already donated around ~$100K this past year. We just didn't announce it.
With revenue increasing, we wanted to increase our donation to the foundation to $128K per year going forward, and Synadia were keen to match. The only reason we announced it this time is to encourage other companies to join us.
Finally, as I wrote in TB's post [1], both companies have already donated the first installment, and Derek and I have also both been donating as individual donors in our personal capacity since around 2018.
Hope that clears it up for you! :)
Please join us and consider donating (or increasing your donation): https://ziglang.org/zsf/

Very well done, sir! Now you challenged me to make a donation also. However, as an individual I assure you that it won't match yours.
That's a pledge only! Let me know when Synadia & TiregBeetle actually send money to Zig Foundation.

I realize not everyone will care about this, but I find the naming for these WSL-like subsystems is confusingly backwards. i.e. It should have been Linux Subsystem for Windows, or Window's Subsystem for [Linux | FreeBSD | etc].
Before WSL, Microsoft provided "Windows Services for UNIX" to "Seamlessly integrate Microsoft Windows into your UNIX environment."
The same Windows services are provided to "Seamlessly integrate Microsoft Widows into your Linux environment."
WSU became WSL!
United Airlines Flight 173 ran out of fuel while circling Portland International Airport trying to troubleshoot a landing gear. Six more minutes of fuel could have helped the airliner to land in the Columbia river by the airport or belly land on the runway. The captain chose to keep troubleshooting and crashed just 6 miles away from the airport.
9front commented on Why do we need MAC addresses? immibis.com/blog/why-mac-... · Posted by u/immibis
the internet predates MAC addresses - it was originally running over serial modem connections.
True. In the Second Edition the Preface mentioned that "Finally, the number of UNIX installations has grown to 10" and some of those systems were connected mostly via telephone lines.
The article refers to a "typical packet found on a typical network" then describes an Ethernet frame, so the author clearly refers to MACs in an Ethernet setup.
MAC is part of the Ethernet standard. The clue of why is needed for is in the name "access control". Without MAC there's no Ethernet. Without Ethernet there's no Internet.
Wait ...there are other networking standards!
