$35 Manta Sleep Mask has drastically improved my sleep


Meta comment: I really appreciate comments like this that breakdown problems to the first-principles physics and show their works. Thanks!


Full disclosure, I now think I badly messed up the capacitor energy calculation perhaps while recasting it from a battery system to a capacitor system. You probably don't need nearly that many just to store the energy usefully. But I estimate the other factors, like the discharge curves needing you to over build to get enough energy into the first 5ms, balance it out at to something vaguely fridge-sized anyway.


You perfectly articulated how I feel about python and why I am trying to move my team’s projects to Go.


Hopefully Go being such a bare bones language with unsound features will tire you out soon enough to follow the sibling comment in moving to C# instead :)


If you don't want type errors, go is not the best language to pick.


Anyone know what tool they used to make the flow diagrams? They seem to be text based and might be superior to mermaid.



Looks like monodraw, it was also on HN again a few days ago.


monodraw seems MacOS exclusive unfortunately :(


https://asciiflow.com will probably do


thanks


Does anyone have solid recommendations of reliable household appliance brands? If all the consumer brands are shit, would it be worth going commercial?


Look for commercial brands that have a small residential market.

If it's large, it can become shit on its own, so beware.

Commercial things are great but BE AWARE there may be things unexpected about them. Like noise is usually not an issue for a commercial item in an industrial kitchen.

Check used prices on commercial gear. Anything that maintains a used price after 5-10 years indicates a valuable brand. If you can't find any used ones being sold, it probably becomes crap. Auction sites (not eBay, but like physical "business is shutting down" auctions) can be good for this, if you can see the price they went for.

The only brand I'm really "all in" on is Speed Queen. Everything else so far I have been in the "I'll buy it scratch and dent cheap enough that I won't be sad if it explodes" - Best Buy clearance has been good to me here.

How did the ancient city deal with sewage and waste?


Tenochtitlan had a sophisticated system of urban planning with zoned public bathrooms (latrines, really) that were cleaned at night by a large labor force dedicated to keeping the city clean. The waste was collected by canoe from these bathrooms and dumped into the canal system where it decomposed and was later dredged up to fertilize and replenish the topsoil on the chinampas. Fresh drinking water was provided by mountain spring connected to the city by several aqueducts built in the 15th century.


If you are looking for a really good book about the history of water in America(especially dams), check out "Cadillac Desert" by Marc Reisner.


Doesn’t the go compiler support stripping symbols and debug info from the binary?


I am in a similar (age, mobility) situation and I got into indoor rock climbing about a year ago. Since then I have lost weight and gained a ton of muscle. I go around twice a week.

I always hated going to the gym because it was boring, but rock climbing is fun and challenging, like solving a puzzle. Also, I find I work a bit harder because it triggers your animal instincts of not wanting to fall. I do mostly top rope climbing(bouldering scares me). If you have a rock gym nearby, setup one or two trial sessions and see if you like it.
