Anthropic submitted two sworn declarations to a California federal court late Friday afternoon, pushing back on the Pentagon's assertion that the AI company poses an "unacceptable risk to national security" and arguing that the government's case relies on technical misunderstandings and claims that were never actually raised during the months of negotiations.
The Department of Defense alleges the AI developer could manipulate models in the middle of war. Company executives argue that’s impossible.

A California jury determined that Elon Musk misled Twitter investors before making a $44 billion deal to buy the company in 2022, reports CNBC. The New York Times reports that Musk had testified this month that he didn't believe his posts would spook markets, but he did say that "If this was a trial about […]
At the time, Musk had tweeted that Twitter had too many bots, which is why he was trying to renege on his commitment to buy the company.
The verdict, while not a complete loss, could still cost him billions.
I go on a lot of backcountry trips where I barely get cell service. If my group splits, nobody knows knows where anyone is until you regroup at camp or at your destination. You can buy Garmin radios or try to set up an ATAK, but ATAK is Android-only and assumes you have a TAK Server running somewhere to make use of all of the functionality. Cool tools themselves, but expensive to set up correctly. I just wanted two iPhones to share their location directly over Bluetooth when cell coverage was lacking.
Red Grid Link does that. Start a session, and anyone nearby running the app shows up on your offline map. When they walk out of range their marker stays as a "ghost" that slowly fades.
The hard part was making sync reliable over BLE. The connections drop all the time. Someone turns a corner, walks behind a vehicle, whatever. I built a CRDT sync layer (LWW Register + G-Counter) so there's never merge conflicts. Each update is just under 200 bytes (from what I have tested so far). When a user/teammate disappears the app does exponential backoff from 2 to 30 seconds before giving up and marking them as a ghost.
Everything is encrypted (AES-256-GCM, ECDH P-256 key exchange per peer pair). Sessions can require a PIN or QR code to join. It also offers offline topo maps with MGRS grid coordinates, same system as in my other app, Red Grid MGRS.
The app is free, and I'm looking for some honest feedback from other real-world users. Let me know if you have any questions!

Fatal brain infection was thought to be from profound immune suppression. Not anymore.
Yes, that Fortran.
