If you change your UI to place the AI button exactly where the most used button in your entire app was, I wish you not just unending gastrointestinal distress, but to stub your little toe at least once a day, and to get a splinter under your fingernail at least once a week

I’m on a flight next to a guy who is listening to Seinfeld with no headphones and all I hear is the laughtrack and the worst bass noises of all time every 15 seconds and all I can think about is this.
Pftompkins.bsky.social: The music of Seinfeld, divorced from the show itself, is nothing short of disgusting. Imagine if the show didn’t exist but the music somehow did. Hearing it, your face would twist in angry revulsion

you don’t hold "AI" accountable; you hold AI developers, vendors, and corporations that profit off it accountable holding "AI accountable" is like holding a toaster accountable. it's an inanimate object. it doesn't have wishes, feelings, or desires

sure, however i do know people at companies trying to do the folding laundry robots (and amusingly there's much more interest outside of the US, but I digress) and yeah bang for invested buck is not scaling out. The robot tech IS getting better though; but yeah it requires insane training amounts.

one set is easy and one set isn't. it's not like they're NOT trying to make domestic chore robots, its that when they fuck up the robots breaks something or hurts someone! in any case it's neat to see what whacky amounts of linear algebra can produce!

it is really hard to not hold this position whenever i was able to build a career for myself with absolutely zero education in the field. i didn't have to buy any books, pay for any classes. everything that i know was learned through free information that was accessible to me starting at the age 10

But there's just a lot of stuff to do in net80211 to be able to mark and validate the correct frames as needing MFP for TX and RX and then multicast needs a /different/ approach, and action frames need a third magic approach. Which is why its taking me so long to do it in my copious spare time :-)

Adrian Chadd @erikarn.bsky.social · 05/10/2026
yup, i've been paying attention to that. I've been plumbing in the PMF bits through net80211 and cleaning up the crypto/cipher APIs whilst doing so. I'm now at the point where i need to actually /make/ and /verify/ the frames. In STA mode where the HW supports it fully offloaded? Its easier.

If you're curious, the stack is here so far - reviews.freebsd.org/D60286 . There's 12 diffs so far and I'm working on a few more at the moment.

Like, I just really like making stuff work, making working stuff better, and building new stuff that works. I wish I could do this full time. In any case, I'll keep chipping away at it until I get all the non-11n bits updated, land it and let it bake in -16. Then its back to net80211 and MFP/WPA3.

I'm slowly updating the #freebsd intel 7260/etc driver (if_iwm) to OpenBSD circa 2021. It's a checkpoint I chose because it has working 11n support. It's a big leap and there's a crap load of stuff to refactor and port over so the next leap (11ac and 2026) will be easier. I .. missed this. A lot.

So, know how over time packaging and packaged food / drink amounts keeps trying to trend to smaller amounts for more money? Not ocean spray cranberry juice. Those fuckers fill up the container so high you can't avoid spilling it everywhere when you open the bottle. Props to Ocean Spray.

i know, but (a) I'm gonna need to pick some up, as we're out, and (b) I've stop taking it on time to see if things are healing or not. I haven't taken one in 18 hours now and the bulk of the pain is gone, which is good. It's just a bit odd feeling, not pain feeling.

So last night miss 8yo sat me down after she did some writing to show me some math problems she had just thought up. Readers, she was doing algebra. With variables. So I did what I do, I gave her a question - X + Y = 20; X + 5 = 8 .. and she was like "DAD I AM A MATH NERD BUT NOT AN ALGEBAR NERD!"

"I'm supposed to be a tough guy," Curtis confided. "I can hold your hand," the mayor offered "What happens if I faint?" Sliwa asked. "I've got you," Mamdani assured him, grabbing his hand as Sliwa received his flu shot. abc7ny.com/post/nyc-may...

so today i'll be making snickerdoodles and picking up a birthday card for reasons that can only be explained as "miss 8yo takes 12 hours to process the previous day at school and only tells me about things she wanted to do just before it's time to go to school and then her sadness/anxiety kicks in"
