I looked at adding USB-PD as a replacement for a 12V barrel-plug power supply in a recent project.

One big issue that came up (and killed the idea) is that if you are not battery powered, then putting a USB-C power input on your device that will only work if you can negotiate 12V+ with adequate current will just cause confusion. In my case, I don't think I could even boot to an error message on 5V.

Phones and the like don't have this issue, since they are still usable (charging slowly) on 5V, but can make use of higher voltages and currents to charge faster.

So I guess my question for the implementer is how booting & negotiating on 5V and then accepting higher voltage is likely to work in practice.

In those cases you have to use a micro or purpose built controller chip to negotiate a higher power input while running off the 5V (bootstrap with dead battery mode). There are chips out for it including power regulation built in.

Autonomy subscriptions are how things are going to go, I called this a long time ago. It makes too much sense in terms of continuous development and operations/support to not have a subscription -- and subscriptions will likely double as insurance at some point in the future (once the car is driving itself 100% of the time, and liability is always with the self driving stack anyway).

Of course, people won't like this, I'm not exactly enthused either, but the alternative would be a corporation constantly providing -- for free -- updates and even support if your car gets into an accident or stuck. That doesn't really make sense from a business perspective.

Eh they are offering a one time payment for autonomy for $2500 which is equal to 4.1 years of paying $50/mo.

It's not a unreasonable cost for development but also maintenance of the self driving system.

Not going to help the tech industry given their largest audience bases are in blue states, who will happily just regulate them to death if the federal government doesn't.

Yes, of course AI offered by a company can be sued. The reason corporations became legal people in the first place was specifically so we could sue them.

In theoretical sense sure.

In a practical sense? They are invulnerable due to what can be extreme financial obstacles they can put in place. They can drag a court case out until you fold if you haven't found a lawyer willing to do it on contigency.

Well on the one hand, an obviously terrible solution is not inherently better than doing nothing. ie, LLM mental healthcare could be _worse_ than just letting the current access times climb.

My other stance, which I suspect is probably more controversial, is that I'm not convinced that mental health care is nearly as effective as people think. In general, mental health outcomes for teens are getting markedly worse, and it's not for lack of access. We have more mental health access than we've had previously -- it just doesn't feel like it because the demand has risen even more sharply.

On a personal level, I've been quite depressed lately, and also feeling quite isolated. As part of an attempt to get out of my own shell I mentioned this to a friend. Now, my friend is totally well-intended, and I don't begrudge him whatsoever. But, the first response out of his mouth was whether I'd sought professional mental health care. His response really hurt. I need meaningful social connection. I don't need a licensed professional to charge me money to talk about my childhood. I think a lot of people are lost and lonely, and for many people mental health care is a band-aid over a real crisis of isolation and despair.

I'm not recommending against people seeking mental health care, of course. And, despite my claims there are many people who truly need it, and truly benefit from it. But I don't think it's the unalloyed good that many people seem to believe it to be.

There's also the elephant in the room that mental healthcare, in particular for teens will probably just be compensating for the disease that is social media addiction. Australia has the right idea, banning social media for all goods.

While we will never be able to get folks to stop using AI to “help” them shape their replies, it’s super annoying to have folks think that by using AI that they’re doing others a favor. If I wanted to know what an AI thinks I’ll ask it. I’m here because I want to know what other people think.

At this point, I make value judgments when folks use AI for their writing, and will continue to do so.

It's kinda funny how we once in internet culture had "lmgtfy" links because people weren't just searching google instead of asking questions.

But now people are vomiting chatgpt responses instead of linking to chatgpt.

I feel like part of this is people not being comfortable with the idea that they don't have to be deferent to the robots (i.e. do what you want, it will avoid you). That's perfectly understandable (nobody wants to walk in front a moving industrial robots), but is something these companies will have to work on if they want people comfortable around their bots.

Sounds like the robots don't do a good job at avoiding

> Because a PE fund is at most a seven year timeline

Berkshire Hathaway is a PE fund with permanent capital.

Broadly speaking, making generalisatios about PE is almost impossible because it's an asset class which is, essentially, all non-public business. Instead, it's more useful to think about which element private equity touches you're specifically complaining about: capitalism in general, financial transparency, leverage and liability.

delfinom · 7 days ago

The problem with PE is only the hyper aggressive and generally terrible ones make the news.

The quiet ones that simply run business well, don't make the news.

There are PE firms that specialize in rescuing distressed companies with potential and turning them around. In many cases not firing anyone and holding onto the form they acquired for a long time.

>> Red Baron frozen pizzas, listed on the shelf at $5, rang up at $7.65.

The crazy thing is that even if it did ring up at the correct price it isn't a good deal. It's around $4.80-4.90 at Walmart and Target and others.

delfinom · 7 days ago

It's worse than that. In many cases the dollar stores now get skus of items made for them that are "cheaper" than a sku in Walmart but for a more expensive unit price than Walmart as they shrink the product.
