PVC used in water pipes had some surprises, the lifespan there turned out to be less than optimistically expected when PVC pipes came to the market. 100 years might be hard to test for...
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 means if anything the traces can be less wide. The size of the traces is determined by the current they carry, the voltage determines how much space must be between the traces (but it’s unlikely to be an issue at these voltages).
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/million per month job, but you have to have meetings all day long, you’re not really rich. Similarly, no offense to billionaires, but the ones I’ve met have been someone manic and misanthropic. If you are using your access to spend your time with them, you are not really rich in my book.
True wealth is being able to spend all your time doing things with and for people you love. It sounds trite, but the truth is many people miss the opportunity to jump off the train and enjoy their life while they can.
A few years back I took some mandatory training. As part of this we were told to write down our personal goals which we all did. Then the trainer said something profound "I can tell you are engineers - mostly I give this class to executives who get mad when they do the above exercise. They realize their goals are things like spending time with family and yet instead of going home after this class they will be getting on an airplane to get to their next meeting".
I would love to have a private yacht, or whatever other symbol of wealth you can dream of. I have plans for what I would do with a house more than double my current house in size. However it isn't worth going into upper management to get those things.
La primera pregunta es: Que es mas macho, pineapple o knife?
Well, let's see
My guess is that a pineapple is more macho than a knife
Si! Correcto! Pineapple es mas macho que knife
La segunda pregunta es: Que es mas macho, lightbulb o schoolbus?
Uh, lightbulb?
No! Lo siento, Schoolbus es mas macho que lightbulb
Gracias. And we'll be back in un momento
I wonder how that'd go. Like in French "the book is on the table" is "le livre est sur la table" so I guess it'd become something like "he book is on she table"? We might need some new words. Or just steal the French ones "le book is on la table"? Vive la franglais!
Old English had gender, and the feminine definite article to match masculine the would be theo. (The whole concept of "the" was a late addition, mind you, and Middle English followed soon after and got rid of grammatical gender, apparently because an influx of Nordics had trouble with pronunciation.)
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 of a multibillion dollar company single handedly. It sounds hyperbolic, but it’s not in this particular case.
I’m also fairly convinced he didn’t capture one tenth of one percent of the value he created, so I’m not sure how anyone can argue this is ‘unfair’.
As someone that was previously bullish on Workers but now fully disillusioned with a barely positive cost basis on it right now I disagree with this - if anything I feel burned for believing and continuing to believe.
Either way, people like me aren’t going to be able to capture even a tenth of the success of joining Google in 2005 or buying a $1m house in Palo Alto ~4 years after graduating (I’m 6.5 years out of graduating) because people like me aren’t as human as the folks that own this house.
Take it easy. These kind of thought won't help you. It's a rough time out there but thing change. Our ancestors survived famines and war. We should be able to manage this.
And yes, life is not fair. But don't waste it, it's finite.
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 afternoon, and if you’re hooked a few weeks of training (spaced over time) will make you into a radically better diver.
We have historical evidence of using hot oil, especially pitch (which is "oil" in the sense of petroleum, not plant oil), e.g. see [1], which provides academic sources.
If we go beyond Medieval Europe, using hot oil was observed by Josephus in AD 67 [2].
I respectfully beg to differ. There are massive chunks of Scotland which have no cellular reception at all. There are many places where there is service from some-but-not-all providers. Of those places, there are a few where the service is glacial in performance.
Example: if you stop at The Green Welly Stop in Tyndrum (FK20 8RY), you'll have coverage from only two of the mobile networks. Vodafone and o2 have a coverage patch there. Have a look at the coverage maps (bidb.uk aggregates them all). It's absolutely patchy, and certainly not contiguous.
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 electric heating?
They're pretty dreadful in that they leak heat while charging up during the night, using (still-expensive) off-peak electricity, when you don't really need the heat, then run out of stored heat quickly during the day, failing to do their job. Maybe in a heavily insulated building they would work better - just my personal experience before ripping them out to install gas central heating.
They don't work particularly well. You're roasting in the night when they heat up, nice and toasty at breakfast, but by the time you're back from work in the evening you're sat in the cold.
