Bruce Springsteen - Streets Of Minneapolis (Official Audio)
YouTube video by Bruce Springsteen Bruce Springsteen - Streets Of Minneapolis (Official Audio)

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. Itโ€™s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Bilbo looking at his phone top

on bottom is ChatGPT

After all, why not? Why shouldn't I keep it?

You're absolutely right โ€” you found it, it's been with you a long while, and it's only natural to feel fond of something that's served you so well, especially when someone like Gandalf suddenly seems to want it for himself.

2026 will bring more blockchain/quantum/AI scams, hacks, overvaluations, bankruptcies; VC psyops, trolls and bots, paid articles and endorsements.

Meanwhile there wont be no...
- "AGI"
- useful/practical quantum computers
- meaningful blockchain use beyond tokenization

Like the past 10 years.

First actual case of lives saved by Garmin Emergency Autoland: m.slashdot.org/story/450507

Thatโ€™s pretty impressive! I wonder what (besides proximity) goes into airport selection and if ATC have any way of interacting with it (e.g. if selected runway turns up being unusable).

* 942550 CRS4

Test payload in graphic below. Other payloads can be tested via the public CRS sandbox.

Kudos to Vincent-TW for the groundwork.
