AI is my CMS
I mean... it's not really, of course. I just thought such a thing would start to trickle out to people's minds as agentic workflows start to take hold. AI agents are already up in your codebase fingerbanging whole batches of files on command. What's the difference between a CMS taking some content and smashing it into some templates and an AI doing that same job instead?

Lest We Forget The Horrors
Just a high five to McSweeney's for the month-by-month documentation of the horrible crap Trump does. Just a paragraph reminder with good links to confirm. I try to keep my own little mental list of things that horrify me. Not to slather myself in, as I don't have the mental health spoons to live like that, but to be ready when I find myself in a…

A Little Arm Chair Businessin’ about Chrome
It was August 5th, 2024 when a federal judge in the US decided that "Google acted illegally to maintain a monopoly in online search". Then November 20th, 2024 when "The Justice Department and a group of states asked a federal court late Wednesday to force Google to sell Chrome". It hasn't been forced yet and I have no idea if it will be.

Nest Cams
First, we had the Nest thermostat. Gotta have that, right? The first thermostat in the history of time that feels well-designed1. Works great. Pleasure to use and look at. Then we got the smoke alarm. Why not — seems nice2. Then we got a free Nest Mini as a promotion when Miranda went Android for a while and got a Pixel phone.

Blood Pressure Monitors: QardioArm 2 vs OMRON Silver
I've got high blood pressure at the moment. My doctor wanted to keep an eye on it. It's tricky as one blood pressure reading isn't particularly useful. You need a whole bunch of readings over time, and that's pretty hard to do unless you're taking the measurements at home. So, I got a home blood pressure monitor. The first one I got was the…

Full Feed RSS
With Paul Kinlan's Full Feed RSS I can now subscribe to Khoi's site where the RSS entries are more than one sentence. It does make me think... would this annoy Khoi? Does he have it that way on purpose, perhaps because he really wants the site to be read on the site? Do I feel compelled to respect that wish, if it were true?

Manuel Moreale: Sometimes I spot posts like Chris’ Media Diet in my RSS feed and I’m always amazed by the fact the people manage to keep up with movies and TV series and the rest of the media landscape. I can totally see how someone posting a post like mine makes it feel like I just bathe myself in popular media.

Confirming "Hide Distracting Items" in new Safari works pretty well for prepping a page to print out. Also *some* of the items stayed hidden as I navigated around site, but not all.

They got @npub1ncs…a6v8 back at the helm at https://css-tricks.com/ he's been doing great cleaning the design up and getting content flowing, including big beefy guides. He's doing better than I ever did, so that's a win.

Big Snow Globe absolutely needs to be disrupted.
Have you shake a snow globe lately? The snow falls for like 4 seconds. That is some garbage shake effort to satisfying snowfall ratio. One shake should be good for like 20 minutes.
