jld··on Who should be held accountable when an AI Agent (accidentally) acts maliciously?
This is not some theoretical, there are lots of existing laws about who is liable for damages caused by livestock.

Some areas are open range. If you don't want cattle on your land its your job to put fences up to keep them out. Other areas are restricted to livestock and it's on the rancher to keep them out of where they shouldn't be.

jld··on SpaceX to buy Cursor for $60B
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··on South Korea Mandates Solar Panels for Public Parking Lots
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··on RAM now represents 35 percent of bill of materials for HP PCs

jld··on The hidden engineering of runways
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.

jld··on Study finds gaps in evidence for air-cleaning technologies to prevent infections
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.

jld··on Processing 23B Rows of Alien Txtbase Stealer Logs
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.

jld··on Processing 23B Rows of Alien Txtbase Stealer Logs
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?
jld··on Roblox is the biggest game in the world, but is unprofitable
Sounds like John Malone at TCI Cable
jld··on Ask HN: Tired of software career. What now?
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.

jld··on Parents who are saying no to "extracurriculars"
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

jld··on MacBook Pro 14-inch and MacBook Pro 16-inch
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?

jld··on Meterorite chunk crashes into house, bedroom, pillow
Pretty common. You can probably find one in your gutters or roof.

This video says 1 per square meter per year. https://www.youtube.com/watch?v=0xD7SvtPAMM

jld··on Art or heist? A Danish artist took $84k and sent a museum 2 blank canvases
He should send another invoice for the extra services!
jld··on A Tour of Grant Imahara’s Shop [video]
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.

jld··on A Tour of Grant Imahara’s Shop [video]
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.

jld··on A Tour of Grant Imahara’s Shop [video]
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.

jld··on Little Free Library
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.
jld··on Please fix the AWS free tier before somebody gets hurt
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.

jld··on Redefining what a map can be with new information and AI
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.

jld··on Redefining what a map can be with new information and AI
So they'll default to showing directions for biking, walking, and transit?
jld··on Mining Bitcoin with pencil and paper: 0.67 hashes per day (2014)
Banks are companies and their service is to create new money.
jld··on Spotify is letting employees work from anywhere while paying SF and NY salaries
In a world where employees need to show up to 6X Co HQ everyday to work, the cost of living and the cost of hiring is directly linked (6x). But in a world where people can work anywhere, salaries will be disconnected from housing costs and we may see a lot of 6x companies happily slide lower. It will come down to how many employees meet the 6X Co's hiring bar and how good 6X Co is at turning new hires into productive employees. If there are enough available people above their current headcount, the floor will be closer to 1x. How close to 1x (2x? 4x? 5.5x?) is hard to know. I don't think it's simple to know where the market will fall after a remote work revolution.
jld··on Launch HN: Tint (YC W21) – Embed insurance into any product
I've always thought Kickstarter should offer insurance that the creator will deliver the products they're selling.

It would be hard to assess risk between all the different kinds of creators/levels of experience delivering/types of products sold, but I think it would be an interesting product for them.

jld··on How do wombats poop cubes? Scientists get to the bottom of the mystery
> As for what the world is supposed to do with this new information, Hu admits that it’s “not going to replace the way we manufacture plastic.” But the wombat’s strategy could help engineers design better ways to shape valuable or sensitive materials, he says.

I am amused that every researcher is asked to defend how their research will help industry, as if there is no value in the pursuit of knowledge that has no known application. No one starts studying wombat poop because they are hoping that they can someday make some industrial process 1% more efficient.

jld··on Protocol for a U.S. Nuclear Strike
The people receiving the orders are trained to understand that they do not/will not have full situational awareness. The president issues the orders and they carry them out.

The presidential football is basically a menu of strike options that are ready to execute. To launch a strike all the president needs to do is call the number in the book, authenticate himself using the a two letter challenge code, and tell them which strike from the menu to order. Targeting is preprogrammed and designed to eliminate any delay or nuance in the process.

The US has spent billions (trillions?) of dollars on its nuclear strike capabilities and the systems that order its use. To presume that these systems will fail precisely when they are called upon seems short sighted.

jld··on Mark Rober (former NASA) launches a 30 day Creative Engineering Class
After his latest video I was wondering if his recording of the thieves in their homes runs afoul of wiretapping laws. I can appreciate that someone who just stole a package probably isn't likely to try to press charges, but made me wonder if he is just assuming that risk.

Maybe the box has a 'shrinkwrap' license agreeing to be recorded?

jld··on Why Doctors Hate Their Computers (2018)
It's like asking "Why do pilots hate airplane food?"

It has nothing to do with why pilots are/aren't epicures, and a more to do with their bosses deciding to serve them crappy food.

jld··on Yandex Image Search is better than Google with “fuzzy” images
Google image search seemingly has become more about identifying your image and then searching for different images of the same thing. It’s really not a useful tool for identifying a particular image any more.

Yandex is my go to now.

jld··on Amazon Warehouse scam: 16TB HDD swapped for 8TB, returned for full refund
I have had luck having Amazon credit me back part of the purchase price when I need to repair what they sent me. Their chat agents have refunded me 20-30% of purchase price for keeping defective items like yours.
