If you think affordability of healthcare is important (and it is for many Americans, even if they haven't been following the news on these expirations), please contact your representatives.

There's about three weeks left before the subsidies expire on December 31, but really there's less than 8 days, because Congress goes on winter break next week:

How much will they go up? A lot: anywhere from 30% to 300% (quadruple!), depending on your income level, and the relative impact is worse the lower your income level.

Specifically, what is expiring is the temporary expansion and enhancement of the ACA’s Premium Tax Credits (PTCs). (The statutes enshrining this come from 26 CFR § 601.105, Rev Proc 2023-29 and Rev Proc 2025-25.)

When these credits go away, the effective price for healthcare goes up for many plans.

I set the schedule so it's running while I take the kids to school. Blissful ignorance of machine stupidity.

Oh, by the way, Dekoda is also in trouble because it turns out it isn't really keeping your data private as promised: arstechnica.com/gadgets/2025...

Couldn't agree more. Has there ever been a movie in which a large manor estate was *not* also the location of terrible events?

The thermosphere (~50 to 600 miles above ground) is very hot (~2,500° F) because of the absorption of solar radiation. There just isn't a lot of mass since the density is so low.

Either way data centers in space is exceptionally stupid.

How are you seeing the question get asked? Can easily believe that over 50% of folks are (say) using a conversational interface once a week. But I'd be very skeptical that (say) 50% of folks have a production agentic capability deployed.

Also agree it's not FDE, but I do think "engineers at customer sites" can add nonobvious value. Thinking here of past engagements where there isn't a lot of cultural impetus or freedom to create products, but the simple act of building something that scratches an itch moves mountains.

No, I agree with you that the service-to-general-product thing is unusual. But I do think that the opportunity for making *internal* products/platforms is one that gets exploited well by capable consultant-engineers, and it's hard to do that well if you aren't embedded or listening to customers.

I remember being excited by Subversion getting introduced at my internship because I thought literally anything was better than CVS.
