@ryanc @owen I don't run my own mail, mostly because I'm on a DOCSIS pipe that (despite being a static) is probably part of a larger netblock that's on spam blacklists.

At some point maybe I'll look at getting a box in a colo or something to do that but right now I don't have time to deal with the hassle of actually making my mail be delivered.

I do want to move to a managed mail host that is anything-but-ms365 though, since my previous mail host rolled up their in house operation and turned into a 365 reseller

@ryanc @owen I mean I have my own local CA with two different intermediate CAs, but I also run my own DNS.

And I need the CA to issue client certificates to VPN clients (I have a ban on password authentication, to the extent supported by the service, for anything network reachable). Once you have that infrastructure in place also issuing your own HTTPS certs is straightforward enough.

But it's certainly not something the average person wants to deal with.

@gigabecquerel please figure out how to build a detector around scintillator frog

It's 3 in the morning on a Saturday and I'm trying to use SLURM to spawn a batch job on a Linux frontend node, which SSH's into a Windows 11 VM, spawns a msys2 UCRT64 shell, then runs a bash script in it.

Not even the KPDH soundtrack I'm blasting is enough to excise the demons here.

Progress! I am now able to run the entire build flow end to end.

All of the unit tests fail, probably because there's no Vulkan in the VM (I guess there's no llvmpipe in windows). So fixing that is probably going to be the next step.

Actually, first I want to shut down and wipe the VM to the snapshot and make sure none of my debug attempts borked anything that would make it fail from a clean slate.

Tossed a PCIe passthrough GTX 1630 in the builder VM and fixed a few other things and now it's churning away again.

We'll let this build do its thing and hopefully it'll pass tests, if not I need to troubleshoot further.

Gotta love those plots of 100% CPU usage lol. No sense having all this big iron if it's not going to be put to use.

Huh, weird. All of the tests passed *except* the Vulkan sanity check which crashed with c0000135 and no stdout.

This is exactly backwards. Expected outcomes are

* this test fails, so does everything else because vulkan is broken
* this test passes, one or more other tests fail due to a bug
* all tests pass

The sanity check code is practically copy pasted from the other tests just not doing anything besides init. Why is it failing??

But this is where self hosting is helpful. Unlike on GitHub's infrastructure, it's trivial for me to kick off a test job that doesn't shut down and wipe the runner after completion, so I can look at the Windows event log, inspect the generated binaries, etc.

So in another 10ish minutes I should have a better idea of what's going on.

Getting ready to deploy the new switch and realized a major problem: it doesn't have a hostname yet.

My general theme for switch hostnames is hash algorithms although I've expanded a bit due to exhausting the common ones so I'm using MACs etc as namesakes too.

My current fleet is keccak, blake, skein, poly1305, and ethash. All of the SHA/MD algorithms are previously used.

Still no hostname but a new problem: the rails aren't long enough to provide rear support

$DEITY forgive me for I have sinned

Has anyone ever seen an *incorrect* horse battery staple?

Well this is interesting. Last night during the workstation outage the grid power voltage to my house reached the highest level I've ever seen, 257V across the two nominally 120 legs (meaning they were 128.5V RMS above/below neutral). And a day or two earlier it dropped down to 235V.

Almost certainly unrelated, they don't pull enough power for this to make a difference and are on double conversion UPS so the voltage they saw wouldn't change. But the timing is curious, as is the data - things were pretty stable then in just the last few days had some huge swings. I wonder if somebody was testing/adjusting a voltage regulator upstream of me? Can't be related to my solar since this was the middle of the night and the sun wasn't shining

@dalias i guess more generally would the tax be on AWS or the customer?

Like if your tax rate depends on usage and you have 100 customers pulling 10 kW each to make the numbers round, do you tax at the 10 kW or 1 MW rate if they're independent users under one roof?

Does it change if the customers own the hardware and are just paying for rack space in a colo, or if they're renting a third party server?

@dalias given the prevalence of cloud/outsourced compute, how would you implement this? Would AWS have to collect signed certifications from every customer as to whether any given instance was an exempted purpose or not? Or tax them at the full rate regardless, making the entire cloud business model non viable and forcing a transition back to on premises hosting (which I'd prefer but it's a somewhat orthogonal issue)

@dalias @trademark @GossiTheDog the hashes are of advisories they claim they will publish in the future afaik, not patches.

@dalias @trademark @GossiTheDog so easily verifiable if they actually turn up but the hype cycle will have moved on by then and they already got the PR benefit of claiming a huge number of bugs

Cranky again about how Android randomly reserves the right to kill applications for power management or its own inscrutable reasons, even if you have power management settings for the app set to "unrestricted".

So every time I open firefox it's a 50/50 shot whether my incognito tabs from my last browsing session (my default browsing mode to minimize leaving residue in history etc) are there or not.

On a desktop OS, apps randomly being terminated for no reason would be a sev1 issue. On mobile, it's just expected.

@petrillic me and my classmates who moved out here used to joke about the "Microsoft bait and switch" but you could substitute any other big Seattle area tech employer.

You get offered an internship, spend a great summer doing fun work in beautiful weather, go back to school, finish your degree, and get offered a full time job on graduation.

Then you move out there, work through the summer, think everything is great.

And then the fall and winter hits.
