Windows Explorer is once again telling me it’s time for lunch while it thinks for a long time or just eventually crashes. We will see which happens first today.

Folks that have experience with deterministic automation in (esp. in distributed systems) understand compounding error rates well enough to be very sceptical about throwing non-determinism in that mix.

Created a super simple decodable worksheet generator for kids.
The lists of words and categories are AI generated so it’s not perfect but it’s better than anything else I could find for my needs.
You can shuffle and select categories and grade level and print

This is how AI should be used in most industries.
Small chunks, easy enough for a person to read & reason without giving too much planning & control up.

However, I think it's best, given the current state of the technology, to use AI to create small chunks of code that you, as a human, can easily vet, improve, and integrate into the larger system in an architecturally appropriate manner.

Windows 11 & the “new” Outlook seem to have so many bugs.
Some days it amazes me how this is the 2nd largest market cap company in the world & these are 2 of their main products that every business uses.

former NBA player Horace Grant kept wearing goggles on the court even after getting lasik surgery for just that reason

What was the initial reason for the goggles? And did you keep them because you had to, or did you like the look?
[–]officialchicagobulls[S] 298 points 9y ago
I got them because I was legally blind. I wore em because of that for a few years. After a few years I got Lasik surgery, but I kept wearing them without the perscription lenses because I had grandparents and parents come up to me and thank me for wearing them. Their kids and grandkids would get made fun of by wearing protective eyewear playing sports, so I kept wearing them to help make it cool to wear goggles for the kids.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:djvu2vj7yozxcgbaczvkftre/bafkreigxngjnx4xu3pttfzneiqu7ghobufz2r2rjaljft5v27dvf4l6nai@jpeg)

Glad to see you can have the books read to you aloud.
Looks like on ios devices you need to go download premium voices first.
Not as good as Edge’s built in but decent. Typical Apple is 5 years behind on tech

Great conversation. Much more to it than the headlines.
A must-see conversation with Gen. McChrystal — who argues America is stuck in a pattern where leaders lie to Americans, they know they’re lying, WE know they’re lying, and everyone accepts it.
How he’s working to return character to leadership:

Did Microsoft Edge 136.0.3240.50 just break css using max-content for width?
Fixing our app after a bug was found in only this specific version of Edge, no other browsers.
Using max-content is causing the container widths to be shrunk like they got stuck in a trash compactor on the Death Star.

Helping a young nephew build his first pc and it sounds like I need to have him look at the new AMD GPUs.
They sound great for the price but I have decades of scars from terrible AMD video card drivers that make me hesitant.

After a week of the new benq programming monitor I really like it.
I think they could have left off the speakers. They’re bad & everything else looks very nice, even the leatherish cable hook.
They could also make the arm taller. It was to short for me to consider using.
Monitor is great though.

Just started working on the BenQ monitor. Love the ux and craftsmanship on it. Display is beautiful & much more enjoyable to code/read than my Dell monitors (which I really liked until today). Very nice blacks.
Just ordered the BenQ 32” programming monitor. Have been looking at the models for over a year. Hoping it’s as awesome as it looks. It’ll be used in a 3 monitor setup as the main one for text.
