"At some point I realized that rather than do something else until it finishes, I would constantly check on it to see if it was asking for yet another permission, which felt like it was missing the point of having an agent do stuff"

Why don't Claude Code & other AI agents offer an option to make a sound or trigger a system notification whenever they prompt for approval? I've looked into setting this up, and it seems like I'd have to wire up a script that scrapes terminal output for an approval request. Codex has had a feature request open for a while: https://github.com/openai/codex/issues/3052

Great article, but one key difference missing from the software experience is that the person for whom you are installing the washing machine doesn't like it there, and wants it moved over to the others side of the utility closet so that when you open the door it is easier to put clothes from there into the dryer. Also, it's too noisy, we need utility closet doors that absorb more of the sound.

One primary driver of the unknowability of software estimation, is that the customer doesn't actually know, and perhaps CANNOT actually know, what they really want or need until they see something that isn't it. No amount of asking beforehand will bring out this information, and complaining afterwards that they didn't say that doesn't accomplish anything except souring the relationship.

Bill by the hour, and absolutely refuse to bill by the project. It's the only way.

That's when you swap the hinges so the door opens the other way, and you thank the manufacturer for providing such an easy solution to a common problem. It's good to keep things flexible and user-configurable.

Now quick, someone reply with a counterexample of how user configuration complicates the product and increases cost. It's design tradeoffs all the way down...

This is very cool, congrats on the execution!

Seems great for grandparents. Have you tested with older people with frail or arthritic hands? I'm curious how much dexterity and force is required.

Having recently ridden Amtrak, easily the worst thing about it is the fact that they've decided to go with an airline style boarding process where the platforms are treated as a secure area and everybody has to single-file get their ticket checked to get onto a platform.

The whole advantage of a train vs a plane is that a train has many doors, allowing a lot of simultaneous boarding to happen; and they also already have conductors who check your ticket to make sure you are getting into the correct car, and another ticket check once the train is in motion. It would be significantly better at major stations to just have conductors at every train car on the platform in parallel doing ticket checks, rather than just have one funnel.

So is there undeveloped photos in the cameras, or is the film blank/unrecoverable?

jackcarter · 3 years ago

I don't know the answer, but there's a famous lost camera owned by a team that perished on Everest before Hillary/Norgay successfully climbed it. It's possible that the camera contains proof of an earlier first ascent: https://en.wikipedia.org/wiki/George_Mallory#Reaching_the_su...

Kodak has published instructions for how to protect the camera and develop the film, if it's ever found: https://web.archive.org/web/20130303001517/http://www.veloci...

Incredible. Going through this gave me similar sentiments to when i first used my school library copy of Encarta 98.

Question: there are some blurred out areas, how come?

Camera limitation – it doesn't capture a full sphere. That's exactly the spot where I also noticed it.

Also, mechanically, as someone who was paid primarily in RSUs last year, you pay taxes based on their value at the date of grant. This is painful if they go down quite a bit between when you receive them vs tax time.

jackcarter · 3 years ago

This isn't true for RSUs in the USA. You're taxed on the value at the time when you receive them.

Once upon a time I was a young punk with a fairly nice car. I had about 6 years of driving under my belt, and less than half of it was with a manual transmission.

I was up in Palo Alto during a light rainstorm, and we were on our lunch break. I was driving two coworkers in my 1988 Acura, one of whom was an absolute freak who drove his sports car super-aggressively.

I was at an intersection in the left turn lane, waiting for an opening. Traffic was fairly heavy and the roads were slick. I saw a possible opening and took it, but there was a car in oncoming traffic faster than I had anticipated. Having begun my maneuver, I counterintuitively held my foot to the accelerator, rather than stomping the brake, and my Integra obediently sped through the turn without incident.

Both of my coworkers commended my presence of mind and I was relieved that my driving skills were validated. Our company was involved in selling software components, and I have no idea what a "self-driving" car would've done in that situation, but as I had discovered, staying the course and stomping the gas pedal was counterintuitive in that place and time, but ultimately correct and safe.

Hopefully, a self-driving car would have waited for a safe opening to make the turn.

Just because you pay a positive non-zero amount for less than a quarter of the energy in, it does not mean that a device has greater than 100% efficiency, which is not possible.

If heat pumps are 400% efficient then log burners in cabins in the woods are even better.

jackcarter · 4 years ago

A heat pump warms a home more efficiently than using the same amount of electricity for resistive heating. It can do this because it's not generating the heat from scratch; it's moving heat from outside to inside.
