Still a zoning problem. Exclusionary zoning ➡️ supply shortage ➡️ price spike ➡️ property tax spike ➡️ Prop 13 backlash ➡️ THE ARISTOCRATS!


Roko's Basilisk's glaring intensifies!

If we really want to electrify the city, we should have PG&E build out the distribution infrastructure to lower electricity rates from $0.50/kWh to $0.05/kWh. At that price, conversion is a no brainer as it's not worth the cost of plumbing for gas.

True zooming way out, but biotech founders are not feeling this huge purported capital surplus at this moment.

The most common misconception about venture capital is that there’s a scarcity of capital, when in reality, there’s a shortage of ventures that are viable for the model. Venture investment isn’t zero sum – i.e. money that goes to SaaS isn’t taken from robotics. The zero sum…



I cannot wait for the Barque Revival.

You can tell a lot about a culture by how much effort they put into practical things, beyond their utility. This clock in New York’s Flatiron District was made it 1909. It doesn’t need to be nice. After all, it just tells the time. But somebody 116 years ago decided to make it a…

Although Intel got rich and famous on microprocessors, their first product was the 3101, at the time the fastest memory chip on the market. They need a mission, could be time to get back to their roots.

WTF did I just read. "OpenAI requiring 900K wpm of DRAM demand by 2029" Buy every WFE supplier and DRAM supplier under the sun Google will require a similar amount, and other hyperscalers + Chinese players will require nearly 2M WPM of DRAM If these forecasts hold, then DRAM…

The 90s called. They want their strip malls back. TCBY is feeling really left out of that sweet Ponzi dough right now.

Shout out to my dad who taught me to use an arc welder when I was 10 and that if it wasn't dangerous, it probably wasn't that useful or fun.

The comments on this attached thread are an important view into the mindset of Western people in 2025. 90 comments, mostly from technical people and all some version of “but did you know high voltages are dangerous!”, meanwhile you can buy chainsaws, guns, ladders and other…



Peskin in full meltdown right now.

Waymo is coming to SFO! The airport has approved a pilot permit to begin autonomous rides. This rollout will happen in phases—and we’ll keep you updated every step of the way until anyone can request a @Waymo ride right from @flySFO.

Literally $10/MWh or bust.

If you order an Uber, a Tesla Model Y shows up, and the driver uses FSD end-to-end to your destination, how many stars are you giving them?


Who's making AI for DJs? Reverb and auto tune are primitive. We should be dialing the measure, voice, phrasing and language of sample tracks. Sync tracks way beyond tempo.


No shame in building a ChatGPT wrapper. No shame in hyperscaling a negative gross margin business. Woe to the startup that does both of these at the same time.

In case you were wondering how my wife’s sourdough starter bread is going, she said this video is exactly how she feels so far. 🔊 … sound on



They may as well take the butter out of the biscuits at this point. Go Baroque or go broke.

JUST IN: Cracker Barrel unveils new logo. CEO Julie Felss Masino insists people love the rebrand. Is she right?



Early failures in organ transplantation, gene therapy, and CAR-T caused a backlash of skepticism and set those therapies back a decade or two. It's important to develop better preclinical models like organ chips to avoid these pitfalls in the future.

What are counter examples to this? Cases where it’s actually quite important to do it well the first time.



The real question is: what is airlines' edge selling credit cards? Corp travel policies pay for business travel but let the employee keep the miles and cash out via airline cards. They more they travel, the more they skim. Airlines "real" business is just embezzlement.

I used to think "I am really smart, I am just bad at taking tests" was just dumb cope, but LLMs are somehow really dumb yet really good at taking tests, so now I don't know any more.
