Online age-verification tools spread across U.S. for child safety, but adults are being surveilled New age-verification laws and tools are designed for child safety on social media and the internet, but adults are in the crosshairs, say privacy experts.

Age verification risks tying users’ β€œmost sensitive and immutable data” β€” names, faces, birthdays, home addresses β€” to their online activity, EFF’s @mollibroccoli.bsky.social told @CNBC.com. β€œAge verification strikes at the foundation of the free and open internet.” www.cnbc.com/2026/03/08/...

A messaging window.

Me:  I need to get my car washed, but the car wash is just 300 meters away. Should I walk or drive?

The LLM:

Walk.

Reasons, quickly:

- 300 m is extremely short; by the time you start the car, you’re basically there.
- Engine wear and fuel use are high on very short cold runs; it’s actually worse for the car than a normal drive.
- You avoid any hassle with parking, traffic, or queuing space around the wash.
- It’s a bit of extra movement for you and zero extra emissions.

Only real reasons to drive 300 m would be:
- Mobility or health issues
- Bad weather / unsafe walking conditions
- You need the car immediately afterward for a longer trip

If none of those apply, I’d absolutely walk, get the wash, then drive away clean.

Stop what you're doing and watch this video. It's long, but you can watch it at 1.5X speed if you need to. It's worth your time.

Some #AmateurRadio radio fun this afternoon. Tried out making an antenna out of two metal slinkies.

It worked better than I thought! I was able to make four contacts with FT8!

I second this nomination!

I loved driving past Nipper when I grew up in the Albany area.

My mom enjoys Nipper too. Growing up she would always ask my Grandpa to build Nipper a dog house so he wouldn't get wet when it rained.

A sideways view of the elevation between two points.  One represents my house, the other the repeater.  There are several large hills in the way.

Honestly, though, given the terrain, I'm *shocked* I can receive anything to begin with.

RF is gonna RF I guess.

Built a DIY Yagi Antenna in an attempt to reach a nearby repeater.

Alas, my transmissions don't seem to be reaching it. The repeater hears *something* since I hear the curiosity tone, but thats it.

The good news is that it can receive just fine 😁.

Can you spare a minute to help this campaign? Save the RIT Model Railroad Club!

Speaking of RIT's Model Train club, RIT is being dumb and forcing them out of their space without a backup space.

Club members put out this petition to try to help save it.

Made an #APRS digipeater recently, and put it in my attic. It detects APRS from folks driving near my house and forwards them to aprs.fl!

It is powered by a Raspberry Pi, a SHARI and software called Direwolf.

I also made the antenna for it out of some copper wire.
