Yep, the COP goes down as the temperature goes up, and at a certain point it's not worthwhile increasing the temperature.

Stefan-Boltzmann law means radiative heat transfer in space is approx. to the 4th power of the hot side of your radiator. Typical space based radiators operate around 350K. If you can increase the hot side of the refrigeration cycle by 4x (1400K) you increase heat transfer by 256x. Create a radiator design that can operate at this temp (multi-stage Brayton loops, heat pumps, possible liquid metal final stage) with a large enough surface area and now a datacenter in space seems possible.

It's a difficult engineering challenge but physically possible, and Elon is no stranger to engineering challenges.

Some numbers: assume an emissivity of 0.85, assume no absorption from the sun, assume heat rejected from both sides of a panel, a 1m^2 panel will reject 1.45kW/m^2 @ 350K.

At 900K its 62 kW/m^2. Not a trivial amount of heat.

Moved object storage from AWS to CloudFlare and have been pretty happy. No problems with performance so far. Bills were 90% cheaper too (free bandwidth)

Agreed. The market should decide if beef consumption is viable. Ultimately energy is the basis all food production. Cheap and plentiful energy solves the food production and distribution problem, then its just matter of preferences.

Well.. farming equipment are high 6 figures 7 pieces of business equipment (the lifetime operating costs are definitely in the 7 figures.) These are owned and operated by people who I would expect to do this type of research and critical thinking. These aren't normie consumers buying everyday appliances or electronics.

However.. farmers are a weird bunch and they are blinded by brand loyalty or will only buy from an "American" company which ironically allowed JD to stomp all over them because of their dominant market position.

Bootstrapping an electronics supply chain on another planet seems harder than building the dyson swarm itself.

Probably not that flexible without some big cancellation fee. It can take 4-6 months to go from bare wafer to packaged chips.

Investors are not part of the market?

I speculate that they are hitting the reticle limit for models not much bigger than this. Judging by the size of the chip in their demonstrator for a 8B model I'm sure they know this already.

To scale this up means splitting up large models into multiple chips (layer or tensor parallelism). And that gets quite complicated quite quickly and you'll need really high bandwdith/low latency interconnects.

Still a REALLY interesting approach with a ton of potential despite the unstated challenges.

Apple has products in their lineup where they refresh and keep the name. Example: Mac Studio is the same every refresh.

I speculate they gave themselves a lot of thermal engineering margin to bump up TDP with the M-series MBP design (or perhaps they underestimated how good the M-series chips were going to be) The battery being at the TSA limit of 100Wh is quite nice as well. Another benefit is that it now differentiates the "Pro" line from the rest of the laptop lineup quite significantly. For most people the Air has enough power now and its plenty thin and light. The pro line is for "true" pros with actually intense workflows.

I'm a dev and the MBP line is definitely overkill for me. The 15" MBA handles everything I can throw at it.

Congrats on the front page MH, hard to forget fellow Chicago/midwest entrepreneurs.

Fight fire with fire. Anti-drone drones that are near cost parity. Or make some investments to develop, cheap, mobile, relatively short ranged point-defense systems. A middle ground between CWIS and CROWS or a CROWS-like system optimized for drone defense. The engagement distance will be close, but it turns the asymmetry back around.

South Korea is a very young democracy with fresh memories of what it was like under dictatorships. The people very much understand the price it took to get to that point and is not complacent in stomping out wannabe autocrats.

YES. I hit the rate limit in about ~15 mins on Claude. But it will take me a few hours with Codex. A/B testing them on the same tasks. Same $20/mo.

If we can have mass produced fast fashion from runway to store in weeks...

Why not tailored clothing at scale? Have a set of portable body measurements that can be sent to any retailer - make an order and have it sent from factory to door in a week or two.

Or get a size that is close enough - bring it to your neighborhood tailor. Most alterations are simple and not very expensive.

Unfortunately sizing is just a leaky abstraction. You are trying to distill many variables into a single dimension. It will never be particularly great.

Why? I don't see it as particularly onerous. They are simply complying with their country's KYC requirements. I've gone through worse to accept payments from US citizens with a US corporation. KYC/AML is annoying but its pretty unavoidable unless you want to do crypto.

Hundreds of millions over what time frame? I got a system with Rails/Solid Queue + Postgres and doing about 20M jobs/day on a $45/mo VM with plenty of room to spare.

Count your blessings.

Yep, thats a good one. Caffeine is deadly to insects, but a mostly safe stimulant for us. Nicotine also comes to mind. Plants have developed tons of defense mechanisms that are deadly to one class of animals, but useful or only mildly deterrent to others. Avians are immune to capsaicin, but an irritant for mammals.. except for some hairless primates.

Its the same evolutionary patterns that plants went through.

Most mushrooms are edible because their spores can pass through the digestive system of most animals, thus allowing them to spread.

Other mushrooms developed toxins to protect their fruiting bodies - often the biggest threat isn't larger animals, but insects. Toxins that are neurotoxic to insect nervous systems, happen to cause mostly "harmless" psychedelic trips to our brains. Other toxin mechanisms happen to be deadly to both insects and humans.

As proof of this evolutionary arms race, there are fruit flies that have developed resistance to amatoxins.

The pendulum swings back.

What PM thought this was a good idea? This has to be the result of some braindead we need more AI in the product mandate

That is an easily falsifiable statement. If I ask ChatGPT or Claude what MCP is Model Context Protocol comes up, and furthermore it can clearly explain what MCP does. That seems unlikely to be a coincidental hallucination.

I think the apt comparison is the rental car business. They are reasonably good at quality standards because the competition is stiff, and if the vehicles aren't reliable and clean, you will just use the company next door. This incentivizes prudent fleet management, and thanks to economies of scale, having in-house mechanics to constantly maintain the fleet quickly becomes cost efficient.

I always found it ironic that Intel benignly neglected the mobile CPU/SoC market and also lost their process lead despite this supposed culture of never underestimating the competition. The paranoid Intel of the 80s/90s is clearly not the one that existed going into the 2000s and 2010's

I can buy 3 or 4 x JetKVMs for 1 PiKVM, pretty hard to justify going for PiKVM unless there is a PiKVM feature you need

Its remarkably straightforward. Not fool-proof, but easy. Bacteriostatic water, single use needles/syringes, and self healing injection port vials makes it simple to maintain sterility throughout the process.

Multiple doses can be mixed and stored in the fridge for 4-6 weeks.

> I have such a hard time imagining a sub 250g drone under 50ft being justifiably something that the state can deny people in such a huge radius.
