Lmao I've had my (used) Ioniq 5 for less than two weeks and when I tried to start it I got a message â12V battery low. Stop safelyâ and now it won't turn on at all. Seems like this is a known issue that Hyundai hasn't been able to fix for years?

I get questions about Graham Platner every time I talk to people outside of Maine. I think this is a very good and measured view of how heâs been campaigning here and why a lot of Mainers are supporting him.

Platner is the presumptive candidate, but is he the right person? My Final Thoughts
NOTE: Almost certainly this piece will travel beyond my usual readership, so I thought it wise to add a quick preface.

Explosive diarrhea is just aggressive top-of-funnel leakage. The viral velocity is high but retention is zero. Your unit economics are totally broken.

WTF does âwipe out those debtsâ mean?? Bail them out by paying off their creditors? Because otherwise if the debts aren't getting paid then the companies can just go bankrupt without even a dollar of government funding.

OpenAI just announced their custom inference processor & close partnership with Broadcom, specifically calling out Tomahawk switches. So reading between the lines OpenAI aligns with SUE (Broadcom-proprietary Scale-Up Ethernet)

What does an AI company do after one of those not-acqui-hire deals? Groq raised money, is leaning into its neocloud business, and is hiring new execs.

I wrote a bunch of open source software that businesses made a lot of money with (Linux kernel drivers/infiniband and libibverbs gotta be 0.1% of Nvidia's market cap) and I feel great about it. I put it into the world hoping people would build on it to do cool stuff and they did!

Musk likes to talk about how great Grok is, but Xai seems to have fully given up on their own stuff (spending $60B on Cursor notwithstanding) and pivoted to being yet another neocloud? Not sure what their moat is beyond being most willing to violate environmental regs.

Weirdly written story - the âauthorities saidâ caveat very much seems to apply to Autopilot or FSD being engaged. The video shows the car absolutely flying down a suburban street and straight into the house, which doesn't look like an ADAS bug - more like the driver trying to blame a crash on ADAS?

Very useful post - as I've said before maybe a lot of these companies don't have enough runway so investors get wiped out, but given all the capex and R&D spending that already happened, the business of serving model inference is wildly profitable at huge scale

If you're thinking of stacking 4x Mac Studios with 512GB each, you might be better off with a GB300 from Nvidia? Only 748GB of memory total but 7 TB/sec of HBM bandwidth and something like 30X the FLOPS
