Is “The Substance” a modern, contemporary, less comedic version of 1992’s “Death Becomes Her”?

明けましておめでとうございます!

Some mathematical observations in 2025

• 45^2 - yeah that one is a bit much
- (So also 2025 = 9^2 x 5^2 and 3^4 x 5^2)
• Σ n^3 | 1-9
• 40^2 + 20^2 + 5^2

While diving deep down a media product placement rabbit hole, I came across this, and had to stifle a giggle while humming a song from my youth a long long time ago ...

In things I did not need to see today but still found impressive:

A Toyota minivan drifting through an interchange ramp.

I haven't had to think about this in a while, but here I am.

What MTAs/SMTP Clients support both:
1. DKIM-signing outbound mail (milter/etc OK)
2. Per-sender-address SMTP relay configs

From what I can tell, MTAs like sendmail, postfix, etc do 1, but not 2, while things like msmtp do 2, not 1.

Just to be clear since there seems to be some confusion. The tsunami warning is due to the M7.3 about 50 miles off the coast near Eureka.

The quake many in SF felt in the same timeframe was much more likely to have been the M2.5 quake near Cobb.

I go away for a couple of days and I get three UC Berkeley WarnMe messages about shots fired around campus.

Fun times.

When you get mail from the CIO ... about the Retirement Savings Program ... you know something got compromised without even reading the mail.

On final to SFO 28R on UAL648 (N19130) (20 mins early) w/ JBU1515 (N976JT) on parallel track ahead of us at our 10:00 for their approach to 28L (?) when both initiate go-arounds ~500ft just short of the runway.

Thought maybe <min separation and asked. Nope.

Campus Datacenter generator test fail, lots of stuff broken
@ UC Berkeley

Even WiFi/Wired Network access is down. [ignore the part about "not to [expect significant impacts to] on-campus network connectivity" - that's clearly (already) out of date.

On our Linux systems, we run into OOM - Out Of Memory - events from time to time (okay ... every week).

For The Cloud™ I'd like to redefine OOM to mean something else resource-related: Out Of Money.

Cloud OOM. CloudOOM. ClouDOOM?

I kvetch about aviation fuckups from time to time.

15 years ago today, though, was an aviation success.

US Air 1549. Bird strike just minutes after takeoff from LGA, dual-engine failure, barely 3000' of altitude, no runways within realistic reach – just the Hudson.

All 155 survive.

I know I made some semi-serious promises a while back to stop going on about Boeing and the 737 Max … but this is a different 737 Max problem, right?

Dear “Custom Systems Integrators” in my inbox.

If you’re going to tout “Thermal Design” consulting for my “AI applications”, you’d better have something quite a bit more than a manufacturer’s info sheet about their prepackaged “solution”.

Russian “mouse fever” eh? Hemorrhagic “mouse fever”?

Nah, that couldn’t be Hantavirus. No Way. Uh Uh. Nope.

This is going to be entertaining - a 6 month closure of 28L @flySFO for taxiway improvements. No mention of addressing the runway subsidence (the runways are sinking about 1cm yearly).

Was talking with someone just yesterday about Adobe's acquisition of Figma.

Doh. Guess not anymore.
