What I’ve learned in doing this type of normalization is whatever the specification says, you will always find some website that uses some insane url tweak to decide what content i…

Famously the actual main library at Pasila has a much larger book collection. Oodi is more of a community space / show piece.

The only thing I can argue with is the thoughts on Starship. Each ship failing in a new way is exactly what you'd expect to see from a research project fixing one issue at a time a…

If it’s underground (meaning not in the sun) the lifespan of PVC is 100+ years. It seems unlikely it will be his problem if it ever cracks.

One tiny nit on this amazing project / write up. He mentions that the traces have to be extra wide to support 24V. In truth though, the higher voltage means lower current, which me…

What so many people fail to realize is the true purpose of money is to avoid having to spend time with people you don’t like, or do things you don’t value. So if you have a $400/mi…

You can tell a company really builds using their own products when an abuse system can take them offline!

They actually like male/female enforced gender. Maybe what they’ll do is add gender to English grammar!

If you’re a Cloudflare shareholder, Kenton has increased your net worth quite a bit. He is one of the few people who is so unreasonably capable he can and has changed the direction…

If you are a SCUBA diver, but always wished that diving was a bit more technical and rigorous, I highly recommend trying cave diving [1]. You can do a cenote tour in just an aftern…

They lost me at dropping hot oil. There is no evidence of anyone dropping oil, it would have been expensive and hardly better than boiling water.

Where in Scotland? There’s 5G almost everywhere.

Those brick heaters are smart because they use electricity at off-peak times to heat the house for the whole day. What about it strikes you as less efficient than any other direct …

What’s your definition of finicky? JavaScript is something like 3-10x faster than Lua for most benchmarks (1). If you’re referring to the event loop, it shouldn’t be all that relev…

Canard aircraft, for example, stall the canard first, resulting in the nose dropping, preventing the main wing from ever stalling.

I would love to see this benchmarked against just running LZW compression on a list of the moves. I think the repeated nature of the moves means the entropy is actually rather low.…

Sure but an $800M investment is supposed to pay off over 10-20 years. It seems like the industry will change in more like 1-2.

It would probably be useful to actually read before you comment. He meticulously cites the sources of his claims with actual studies.

I personally would have added one additional byte, but when it is written I would have added two bits to each of the original bytes. That has the advantage of making each segment 0…

I’m sorry, but once an attacker can run arbitrary commands on your machines, it seems like your personal security battle has been lost. Cloudflare Tunnel isn’t doing anything that …

To play devil's advocate, the American format aligns with how (American's at least) speak the date "March 24th, 2022".

In diving we think in terms of partial pressures. At sea-level, 21% of air is oxygen, and .21 is also your partial pressure of O2. In order to breath at depth, though, we need to b…

The big thing to understand is that you gain a whole atmosphere of pressure every 10 meters underwater you go. So at 100 meters you are experiencing 11 atmospheres of pressure (ove…

Cloudflare Registrar, no markup and a reliable company.
