While gold has industrial uses, isn't most of its value based on the fact that people like it and believe that it has value?

jld — Sat, 28 Mar 2026 23:56:53 +0000

It seems inefficient to put solar panels over parking areas as it requires significant amount of structure which costs a lot more than shade it creates is worth. Especially compared to how much less structure is needed on more remote solar farms.

Maybe I'm just using American mindset where there is lots of open land that is good for solar generation? Perhaps not true in Korea?

jld — Mon, 26 Jan 2026 21:33:54 +0000

I saw a talk a long time ago about the structural aspects of runway design. The most interested fact I remember was that the stresses on the runway generated by departures was higher than those of arrivals, as departures repeatedly stress the same part of the runway, while jets land on a much more distributed area of the runway.

Plus jets weigh a lot less at arrival than at departure.

Double blind studies are helpful when we do not understand they underlying dynamics of a complicated system (like a body) but we want to learn what effect a change has on that system (like a medicine).

If we know pathogens cause disease, and we know filtering removes pathogens from the air (and we can test and verify that) we don't need to run a double blind study to verify they work.

It's the same reason you don't need to run a double blind study on whether seat belts work. We understand the cause and effect of car ejections and windshield/steering wheel impacts on human bodies. Seat belts are designed to mitigate these incidents and are tested and validated in the lab using formal science and engineering.

This is a different feature to allow sites/companies to see which of their users may be compromised to help facilitate resetting credentials.

I did figure out the other issue though. If you got the email saying you were part of the stealer log leak, you can find a link in the of the bottom email titled “check my email address again”.

Follow that link and scroll all the way to the bottom and you should find a section for “stealer log entries” which includes domains that tour email address was associated with.

If you don’t have the email from them, enter it again at the top of the homepage for haveibeenpwned.com to receive it.

HIBP emailed me to tell me I was part of the leak. The blog appears to mention I should be able to see what domains are associated with my email but I can’t seem to find how to access that info?

Have you always felt this way about development? Or is this a newer feeling?

If it's newer, you might just be burnt out and taking a step away from the stuff you hate for a while may be enough to regain your excitement and motivation.

I kinda feel like this is a result of suburban car-centric living too. If every 45 minute practice comes with another 45 minutes of commuting time it eats up all of everyone's time, attention and downtime.

I'm happy to let my kids do the activities they want to do, as long as it's within 5-10 minutes

I think the notch works ok on the iPhone as iOS is specifically designed with it in mind. The small spots abreast of the notch are fine for battery meter, clock, and reception bars.

The Mac notch is right in the middle of the toolbar. I have lots of applications that use that space for menus and will be curious how cumbersome it will be now that we need to literally navigate around it.

Will we need to move the mouse down to get around the notch, or will the cursor be allowed to go under the notch?

I found this video by Zach Freedman about finishing projects to be enlightening, especially the idea that "deciding to not finish a project" is a way to finish a project.

I actually had the idea of "hobby as a service". Create a catalog of a few dozen hobbies to start, and build boxes that are a foothold to the hobby.

Could be: - a cheap ukulele, tuner, with a link to some youtube lessons - a drawing pad and box of pens with some tips on figure drawing - a whittling knife and some wooden spoon blanks.

You receive the box and give it a try. Maybe you like it, maybe you don't but you can always put the stuff back in the box and return the items and receive another hobby to try without the dread of having a drawer full of nice spoon carving knives that you thought you'd love but are now just a symbol of your abandoned dreams.

Where I live, I think a shop space like that would cost a couple thousand dollars a month. Lots of hobbies cost that much (boats, rvs, cars, vacation homes, etc) so it's not outrageous, but also more than I think I could justify given that making do in my basement has no added expense.

If your hobby is making and building, embrace that fact and decide whether it's worth the leap. It might be a great life choice.

I love HN because sometimes the person you’re putting social pressure on is a co-founder of the megaplatform you’re pushing back against.

A way to limit the max spend per month would be great, even if that means creates outages.

I would happily put a $20/mo limit on many of my accounts. They should never bill more than few dollars a month.

I have read that cyclists who only eat beef generate more CO2 per mile than a hybrid car, though that presumably that ignores all the carbon cost of building cars and car infrastructure. Bikes are still better in pretty much every way.

So they'll default to showing directions for biking, walking, and transit?
