Good observation. Yes, because the gable wall isn't load bearing so it doesn't have a load bearing header which needs jack studs.

> non-linear computationally irreducible systems cannot be predicted

How confident are you of your ability to identify such systems?

Many systems are not such and therefore easy to predict.

mRNA could be said to be in the trough of disillusionment -- didn't prevent COVID as initially promised, and has problems like causing heart damage in rare cases.

This disillusionment is evidenced by lower proportion of people seeking to take such injections now.

Is the checklist complete? If not, it might lull you into a false sense of security. How do you know if it's complete or not?

Re:The Moving Assembly Line Turns 100 (2013) on Tuesday July 15, 2025 @01:15PM (#44573518)
It would seem the assembly line also prevents workers from slacking, as they are in constant competition to stay ahead of workers at other stations.

No need for managers to crack the whip. They do it to themselves.

Can't reset state after breakage.

When stuck I do what I call "prepping". Don't try to do the task, just prep for it -- clean the room, the desk, close distracting websites, gather the materials.

It's lowering the activation energy so the reaction can happen more easily.

You can't hold onto it regardless.

The best you can do is choose who gets it.

If people would spend more for the US product, we wouldn't need the tariffs.

Documenting existing system dependencies using the product which which I'm a founder:

Like UML deployment diagrams, but our models are interactive and can be queried.

We also have a large customer doing DDD modeling and then generating code directly from the models they build.

I feel the same way about Farscape.

a brighter room with light screen (not dark mode) causes smaller pupils and thus better focus.
Re:How to improve your WFH lighting to reduce eye strain on Thursday January 23, 2025 @11:20AM (#42805350)
When I was younger, dark room, dark screen was fine. Gets harder to focus as you age. Bright screen and room cause smaller pupils and therefore easier focusing like a pinhole camera.

Constant fans are sucking outside air into your house. Could be part of your Heat/AC efficiency problem mentioned in your post. A timer to run every 10th minute would be a simple improvement.

Place a wick in the center of the puddle and run out out the drain hole and down a couple inches lower than the lowest part of the puddle.

The wick will act like a self-priming siphon, and carry (wick) the water out the hole and drip from the lowest point of the wick.

The umbrella shade explanation might still be valid. There is still infrared radiation emitted from the roof of the freezer to encourage sublimation. It's just not visible light.
