Recently our county sheriff put out an Amber Alert (a forced alert on all mobile devices) but the obfuscated link resolved to Twitter.

I wonder what portion of the public saw the Twitter login page and just closed the tab, never to see the details of the child abduction.

I think homelessness and despair cause mental illness and substance abuse. If we can prevent “normal” people from losing their homes, I think they would be more stable and able to take care of themselves long term.

Allowing homelessness is far more costly to everyone else than preventing it.

An EV engineer friend of mine said that this is specifically the Hertz Teslas because Tesla parts are expensive and sometimes hard to get. So when a Tesla breaks, they sell it rather than repair it.

I rented a Bolt EV from Hertz once. The car was fine, but the charging stations in the area were mostly broken, or they required downloading an app and giving personal information to charge.

I got the feeling the charging networks are all about collecting government incentives and the sale of private information from subscribers, and not at all about service.

My new preferred rental car is no rental car at all.

Ohm my god, right‽

I enjoyed the humor, but the OP did set a boundary of [serious].

So I guess what we are learning here is that setting boundaries is always going to provoke some people to break those boundaries out of spite.

The conviction was about a year after the crimes, which is a lot faster than I would expect than in my country. 5.5 years does seem light to me, too.

The rhetoric is still somewhat apologetic to the perpetrators. Like “it’s difficult for students to resist due to a sense of closeness to their teachers” doesn’t say anything about rank, authority, and power that teachers have over students. And “checking whether a teacher is under excessive pressure” seems to redirect fault away from the perpetrator.

Long ago “drive” meant urging an animal to move forward. And “dialing” a phone number meant entering the “digits” by turning a rotary dial with your digits.

Words aren’t as static as you seem to think.

BYD has a factory in California where they make electric buses and commercial trucks.

A lot of Brazil is in the tropics, so no, not winter kinda latitudes.

But Brazil also extends to something like 33° South, where winter starts in June.

I’m going to go look for an update on DeepSqueak…

No manufacturers can make a dishwasher that lasts 18 months anymore. And they don’t make replacement parts. I’m not in any hurry to add another hunk of electronic junk to my home.

Without reading the article, this smells a lot like #enshittification

I’m surprised this isn’t a named sort of cognitive bias. I think there’s a related thing where we humans tend to cite external causes outside our control when we are unfortunate or make mistakes, and we tend to cite our own virtues when we are fortunate and successful.

I agree with all of that. My intuition is that prior to curing, the polymers are less stable and may change in unpredictable ways depending on subtleties in the storage environment and handling. After curing, the polymers are much more stable and durable.

Metals definitely are more forgiving, and we have better tools for testing, especially non-destructive testing. Whether the CF flaws are due to fatigue or workmanship, it’s easy to miss them in inspection.

I’m also curious what the sub designers saw as the advantage of CF for this application. Is light weight really all that advantageous for a submersible? Generally no one chooses CF if they are prioritizing cost.

Different loads, different failures, but still a valid safety concern.

I would not want my bike frame or fork to be made with expired resin. But the age of the bike after the CF is cured is a different matter.

From my limited experience with laying up carbon fiber, I know there’s the raw carbon fiber cloth and there’s liquid resin that you spread into the cloth. It’s also very common to see carbon fiber cloth that is “pre-impregnated” - the resin is already applied to the cloth. Everyone calls this “pre-preg”.

So I’ve seen a lot of folks online scratching their heads about “how can carbon expire?” or “my carbon fiber (bike/boat/etc.) is N-years old, is it expired?” but I think the most likely thing to expire is the resin. Once the resin is cured it is much more stable.

Any materials folks or structures engineers who want step in and correct me, please do.
