This genuine technological breakthrough is real and should be a main topic when discussing Tesla.

Admittedly, the road to a working version of FSD has been a bumpy one, with many overly optimistic timelines, but now it's finally here, and it is almost completely ignored.

It's a heat battery for district heating. Could be other sources than electricity, e.g. municipal garbage incineration plant.

That is a good question. https://starlink.com/map shows neither Myanmar, Thailand or Laos having coverage.

Perhaps they were using the "roam" version (https://starlink.com/roam), which seems to work pretty much anywhere.

Despite all the fanfare, it is actually still DoD. The decree merely allowed the use of DoW as a "secondary title".

Any idea what "output token efficiency" refers to? Gemini Flash is billed by number of input/output tokens, which I assume is fixed for the same output, so I'm struggling to understand how it could result in lower cost. Unless of course they have changed tokenization in the new version?

Thanks. This comment above does mention ASRock: https://news.ycombinator.com/item?id=43112594

On the other hand, dmidecode output in the article shows:

Manufacturer: Dell Inc. Product Name: 0H3K7P

Were you able to identify the manufacturer and model/revision of the failing motherboards? This would be extremely helpful when shopping for seconds hand servers.

Can you elaborate on this?

I have a proof-of-concept RAG system implemented with LangChain, but would like input before committing to this framework.

Take the announcement with a grain of salt. From German physicist Sabine Hoffenfelder:

> The particular calculation in question is to produce a random distribution. The result of this calculation has no practical use. > > They use this particular problem because it has been formally proven (with some technical caveats) that the calculation is difficult to do on a conventional computer (because it uses a lot of entanglement). That also allows them to say things like "this would have taken a septillion years on a conventional computer" etc. > > It's exactly the same calculation that they did in 2019 on a ca 50 qubit chip. In case you didn't follow that, Google's 2019 quantum supremacy claim was questioned by IBM pretty much as soon as the claim was made and a few years later a group said they did it on a conventional computer in a similar time.

Neat. I am curious what notable differences there are between Modal and Tailscale.

Nothing out of the ordinary, except for that final response.

Interesting. Do you know if your tool supports conversions resulting in multiple files, such as HLS and its myriad of timeslice files?

And, thankfully, high-voltage systems are extremely well-managed in EVs.

Evidence in support of this claim is that EVs are statistically 4-5 times less likely to catch on fire compared to ICE vehicles.

Exactly. Apart from waking up the vehicle and closing the high voltage connectors, a whole myriad of things run off the low-voltage system, including lights, climate, infotainment and most (if not all) actuators.

Cybertruck is the first Tesla vehicle with 800v architecture. The S3XY lineup uses 400v.

This. It may seem like wishful thinking, but the problem of desertification is so immense that we ought to approach any potential remedy with first principles and determine feasibility.

Could passive desalination be a way to bootstrap local ecosystems in arid environments to a degree where it would be self-sustaining?

New comment by crishoj in "Bun v1.0.0"

crishoj — Fri, 08 Sep 2023 19:57:09 +0000

Business plan is outlined on https://oven.sh/:

Oven will provide incredibly fast serverless hosting & continuous integration for backend & frontend JavaScript apps — and it will be powered by Bun.

It will support popular frontend frameworks like Next.js, Vite, SvelteKit, SolidStart and many more — along with backend frameworks like Express, Fastify, NestJS and more.

The plan is to run our own servers on the edge in datacenters around the world. Oven will leverage end-to-end integration of the entire JavaScript stack (down to the hardware) to make new things possible.

This would make sense if not for the fact that heat pumps are far more effective at heating homes than simply sending electricity through a heating element.
