Fun experiment alexwlchan! Two small mistakes in your post: you write "15,000,000,000.00 in" and "that the size of a page is 15 billion inches", but it should be 15 million. You said you had difficulty formatting text. H

Actually it's 0.03% but the mistake is elsewhere. The correct figures are that 1.3M out of 4.36B checked bags (so 0.03%) are lost and never claimed. The infographic incorrectly states "43.6B" (should be 4.36B, to be consisten

Tip for author: you can drastically reduce hardware & software complexity of this project by removing the Arduino and use this library which allows controlling WS281x strips directly from your Raspberry Pi: https://github.com

If "looking nice" was the main factor, people would be buying jewelry made of materials that look identical to gold AND are more durable AND are less expensive.

It's been possible for years to short Bitcoin on reputable exchanges. For example Coinbase and Gemini, to name two of the most regulated and compliant US-based exchanges... unlike FTX which was not in the same category, and definitely

Yup. 10% industrial, ~45% jewelry, and ~45% bullion. Jewelry's use of gold is speculation just like bullion. People want gold or other precious metals in jewelry not because they provide the best physical properties at a given price-po

Only 10% of global gold production is used industrially. Most of gold's price is sustained by pure speculation.

This -15% fall was sort of expected as the ETFs were already priced in, which is why Bitcion went up before their launch. Now Bitcoin is back to $39k, which is early Dec 2023 levels, ie. back when the market thought ETF being approved were

The language surprised me too! I realize the researchers wanted to be extra cautious (enough to pass peer-review) and that's the reason I did a literal quote instead of paraphrasing.

Thanks! So not only preservation of soft tissue was confirmed, although the exact mechanism is not fully understood. But also there are "multiple lines of evidence for material consistent with DNA in dinosaur" found in fossils ht

Anyone knows what research came out after scientists recovered 70 million-year-old T. rex soft tissue back in 2005 ? I remembered being blown away by the fact we could have soft tissues instead of fossilized remains... https://ww

You are probably right. Reading some old notes of mine when I was fine-tuning PCIe bandwith on my ZFS server, I had discovered back then that a PCIe Max_Payload_Size of 256 bytes limited usable bandwidth to about 74% of the link's theo

"1/4 the speed of a Pi" applies to the original (slow) 2012 Pi which is unable to run LLM as fast as you think. However the 2020 Pi 400 (equivalent to Pi 4), which can run the LLM workload, is about 100 times faster than the

Hindsight is 20/20. I'm sure one could go back and read thousands of these internal technical symposium papers criticizing X or Y or Z, and most of those turned out to be unwarranted.

Oh, yes they did. 200-300 GPUs for about 2-4 months at an average $0.10/kWh has a TCO of $100k-200k. 12.5 BTC was worth $375k back when it was solved. So definitely profitable—they would have made around $175k-275k, and end up with ess
