Lazy toot: the Dell R440 has this mezzanine NIC that clearly has a 10G option. Anyone know what the keywords are that I should search for on eBay to upgrade the 2x1G NIC in this box?

@kwf CF4P0 or 0CF4P0

@kwf 0GVXF4 might also work. It is designed for the R540 (same gen) but it's a 2U, so the thermals will differ.

But looks like half the price.

@baloo@sfba.social avatar

@kwf I mean, I don't think you're ever going to have issues with a 0gvxf4. It's a dummy broadcom with very little amount of features.
And it looks like it's less expensive than a mellanox?

Unless you already have connect-x3 on hand?

baloo,
@baloo@sfba.social avatar

@kwf I didn't now x3 were that cheap.

Does anyone remember the MMO hacking game where you start with like a comically slow computer and you dial into other player's "computers" and can poke around in their file system, delete logs, download warez you find on their computer to add to your own toolkit?

It was from like 15 years ago

@kwf isn't this called internet?

My annual plea for a thing: I want a type 1 hypervisor that just has a small isolated VM and then passes through the rest of the hardware to the main VM which runs Linux. The small VM is intended to be used to run small pieces of code that the main OS should not be able to interfere with. Does such a thing exist? (Think Xen, but with a Dom0 that can't see into DomUs)

@mjg59 @hyc
Curious: what kind of hardware should the security VM need to access?
(I can only guess TPM? For state bootstrap or something?)

@mjg59 @hyc
I know you already dismissed SEV, but https://github.com/project-oak/oak seems vaguely related?

This is a VM inside the main OS, but the binary inside the TEE is available over grpc.

some good news: solutions to the nix stuff are coming; so if you’re thinking of mass evacuating the ecosystem please hold off a little to see what’s coming this week

@ktemkin Been holding my breath for over a week now. Currently running out of air.

@ktemkin Hey, I appreciate the good work, and I'm sure many others do too.
Thanks for stepping up.

Me: sending the vendor a detailed reproduction procedure, taking 3-4 hours to complete.

Vendor: we plugged the unit it and it will work fine. We tested all 4 faulty units within 10 minutes.

Thank you vendor.

@kwf "oh but the issue is because you're using an unsupported environment"

"well, first you don't list the supported environments, second, that also reproduces on ubuntu, environment has nothing to do"

baloo,
@baloo@sfba.social avatar

@kwf This vendor has been full of shit.

One of their support agent joined a zoom meeting where we could reproduce the issue in front of them.
The thing will output its error in morse code on a LED.

a month later, another support agent "We believe you can't read morse code".

"Please open the video attached 3 comments up, with the recording of the LED"

Welp. Work has put out the mandate that we start coming into the office one day per week.

The crack has been opened. Now we watch to see how quickly they try and move the goal posts.

@kwf this didn't trickle down to here yet.
Can't wait.

I love explaining complicated subjects in a quippy way that isn't necessarily wrong. For example:

Kubernetes is 20 while-true loops in a trench coat pretending to be a container orchestration platform.

What are your favorite quippy ways to explain a complicated topic? It could be anything! I'm just curious what y'all have :)

@hazelweakly nix is just a fancy way to run bash scripts.

@kwf now the question is: which of those is square one? And can we get back to it?

So I've got this empty concrete pad on the side of my house.

It used to have a rotted out 12x24' shed on it, but I demolished that last fall and figured I could do something better... 🧵

baloo,
@baloo@sfba.social avatar

@kwf what’s the plan for the shed? Put some kind of jacuzzi?

baloo,
@baloo@sfba.social avatar

@kwf The hexagonal shed!

chat, what's your recommended way of learning the theory behind PID controllers and autotuning? i need one that doesn't involve a 150 page treatise on z-transforms and poles in complex plane. i just want to write a script that makes heating in this house tolerable

baloo,

@whitequark wondering: wouldn’t a reinforcement learning approach with a temperature sensor inside and outside be enough?

Life uhhhh finds a way.

3/8” socket ratchet to a digital torque gauge, to a 3/8”-1/4” adapter, to a 1/4” hex, to a 1/2” socket adapter, to a shimano cassette tool.

baloo,
@baloo@sfba.social avatar

@whack that smaller section of the adapter is designed to break under load before the more expensive drill connected to it would.
Worked as designed?

(Also why you should only insert the small part in the drill chuck and not the whole shank)

baloo,
@baloo@sfba.social avatar

@whack yes I can see that. All I’m saying is: this is designed to break here when over the stress limit of the material, and it broke here.

There was a power outage earlier today, so now the printer doesn't have magenta anymore.

@gsuberland and that mdf looks thick. Must have been quite a slow process on the laser cutter.

Also: TIL mdf can be laser cut without fire hazard.
