usr does mean user. It was the place for user managed stuff originally. The home directory used to be a sub directory of the usr directory.

The meaning and purpose of unix directories has very organically evolved. Heck, it’s still evolving. For example, the new .config directory in the home directory.

Or just a decent bus system. You could replace 50 cars on that highway with a single bus.

2 tips.

1. Negative air pressure is your friend. If you open the windows upstairs and down and blow air out of the house it’ll suck air from the downstairs to the upstairs cooling the entire house.

2. Bernoulli’s principle is your friend. Rather than having fans right next to the windows you’ll move more air if you back the fans a meter or so from the window. https://youtu.be/BhWhTbins_A?si=9LGd0_EmfPFBNnDJ

Yes and no.

Some salts are easier to work with than others. Kosher salt, in particular, is fairly hard to over season with because you can visually see just how much you’ve thrown onto a steak or such. Fine salt, on the other hand, is a lot easier to over season with.

But then it also depends a lot on the dish. Sauces are really hard to over season. The sea of fluid can absorb a fair amount of salt before it’s noticeable. Meats are similar. A steak can have a snow covering of kosher salt and it won’t really taste super salty.

Bread, on the other hand, will be noticeably worse if you throw in a tbs of salt instead a tsp.

But salt wasn’t specifically what I was thinking when I wrote that. Herbal seasoning garlic, rosemary, thyme, sage, etc, generally won’t overpower a dish if you have too much of them. Especially if you aren’t working with the powdered form. (Definitely possible to over season something with garlic salt/powder).

I’m pretty much the same way, though I do throw in a bit of fine salt on occasion for the iodine content. I don’t eat a ton of seafood which makes getting the rda of iodine difficult.

Salt :D

Lots of home cooks are shy with seasoning in general (but especially salt). While not impossible, it’s fairly hard to over season stuff.

That’s why if you ever look at “miracle season alls” the first ingredients are usually something like “Salt, pepper, garlic powder, onion powder”.

If you want to be amused, look at these ingredients lists. Often the only difference is what food coloring is used.

For example.

AAA says that EV batteries tend to lose power faster in cold weather, getting as little as 50-60% of their advertised range.

Right, and the EVs that lose that much range are the ones with the smallest battery packs. The heating requirement as a percentage of the battery pack goes down as the battery gets larger. It takes roughly the same amount of energy to keep a 40kWh battery warm as it does to keep a 150kWh battery warm.

The same logic doesn’t directly translate for a car as a bus.

Buses will have fairly large batteries (Bird does 150kWh). The percentage of the battery needed for heat goes down as size goes up because the interior size is relatively negligible in how much added heating capacity is needed to keep the bus warm.

But yes, probably wouldn’t be too crazy to throw on a propane heater in especially cold climates.

1. Electric cars run just fine in icy weather

2. Heatpumps, which work a lot better for larger buses than smaller buses.

Bus routes are generally short, fixed, and planned. They are literally the perfect place for an EV.

The Walmart self checkout layout is generally just bad. Because they are paranoid about theft, it’s setup to make it easy for the worker monitoring to make sure nothing fishy is going on. However, that means that the customers that want to checkout often can’t see what’s open.

This creates lines as the machines aren’t fully utilized.

But further, it’s often the case that for whatever reason these machines need an employee to interact. With 10 machines running at full capacity, that means longer waits for everyone because 3 machines are waiting for an id badge scan.

Walmart can solve some of these problems with more employees but that cost money.

The problem with this is that every vehicle would need to be built around the same battery pack dimensions

There’s a lot of ways to tackle this issue. You could have a couple of standards (think AA vs AAA batteries). Or you could make the packs smaller and more modular so different applications can have more or less of them.

have the same amp-hour rating

No, they’d not need that. In fact, I’d say it’s desirable for them to not have that.

same voltage, same cooling system

Same voltage, yes, same cooling system? Not exactly. They’d just need to have cooling system hookups in the same place.

I seriously doubt that would ever happen as nothing like that has ever existed in the 120+ years of automotive history.

Loads of things like that have existed in the automotive industry. In fact, that’s one of the biggest features of the big 3 automotive manufacturers is having standardized parts shared between one another.

I wasn’t fully aware of NVK and where it’s at. It’s actually pretty exciting. I wouldn’t mind dropping my current nvidia binary blob for fully open source drivers.

Not as bad as you might think. The nouveau drivers have come a long way for maxwell. You should give it a shot if you haven’t. But, unfortunately, if you are using anything new then nouveau sucks. It’s a fun game where you get to wait until nvidia no longer wants to support your GPU and hope by that point that nouveau has progressed far enough that you won’t be looking at noman’s land.

Graphics drivers are what matters. Your orange pi uses a mali GPU which is well supported by Linux (thanks ARM).

nVidia is just barely at the point where their most recent gpu drivers aren’t terrible under Wayland. It’s taken a while to get there.

GPUs with good open source drivers will fare fine.

Standard and swappable battery packs? Yes. All the skateboard style vehicles or ebikes have battery packs that can be removed and replaced.

Making that automated could be nice but isn’t necessary to get the benefits of a standard. A standard forces pack producers to compete with one another in terms of quality and price. It makes it cheaper to install new batteries. And it makes it possible to upgrade your cars range with newer packs. With an EV, you won’t need to get a new vehicle hardly ever if getting new packs is relatively affordable and easy. Further, the worn packs still have value so swap locations will be incentivized to pay you for the pack they remove.

The notion this needs to be part of a giant battery swapping network to reduce charge times is silly. 10 to 15 minute charge stops are already very short and all you need on most cars for the next leg of a journey. It also introduces a lot of complexity. Like, what if I want or need a 100kWh pack but the standard is 80kWh packs? What about pack wear? Who’s in charge of pulling the degraded packs? And what do we do about someone putting in a pack with fake capabilities? You have a situation where you are cycling parts worth well north of $10k. That’s a mighty tempting target for theft.

A standardized battery is still a really good thing. I just don’t think it needs to be a part of road trips.

Every EV has this already. What they don’t have is a standard. Not shockingly, every EV manufacturer will argue why theirs should be the standard.

For your car repair example, it would kinda be like someone got that and then started going to every crash up derby they could find.

No, it’s actually more like you bought the car because you know you’re going to rack up a million miles every year. Out of the norm but not an asshole move.

If Google didn’t want to lose here, they could have not had that feature.

200TB is a lot of data and a completely reasonable amount if you are doing a lot of filming. HD film takes up a lot of space, especially if it’s raw.

This sort of usage is so predictable I can’t imagine Google didn’t consider it when pricing things out. Heck, they advertised the unlimited storage space being useful FOR preserving photos and video.

Why give a company that spent 26 billion dollars making their search engine the default everywhere because they don’t want to spend the 1 million dollars it’d require to continue supporting a product they advertised. They could have ended new sign ups and just supported existing customers.

I’m saying that Google should not be allowed to sell a product with an advertised feature to gain advantage over competitors only to later change their mind and remove that feature when they deem it too costly.

A multibillion dollar advertising company should have to support the products they sell.

If you bought a car and one of the features sold was “free repairs for the life of the vehicle” you’d be rightly upset if a year later the dealer emailed you to say “actually, this was too expensive to support so we are cancelling the free repairs, but you can still pay us to repair your vehicle or we’ll sell you a new one, aren’t we generous!”

but I’m not exactly sure what he was expecting. Storing files is an ongoing expense

He was expecting a company that promised unlimited data to not reneg on their advertised product. Or to simply delete data they promised to store because it’s inconvenient for them.

Yeah, it costs money to store things, something Google’s sales, marketing, and legal teams should have thought about before offering an “unlimited” product.
