Is your favorite color purple?

I'll take School Shootings and Privatized Healthcare for $100, Trebek.

The list is short because historically it has been hard to designate domestic organizations as terrorists without violating their First Amendment rights (among others, I'm sure).

Sec. 3. General Provisions. (a) This order shall be implemented consistent with applicable law.

Glances nervously at the first amendment

You alright bud?

A capacitor has ~1% of the storage capacity of a battery of similar power rating.

Saying its storage performance is better because its holds a larger % of that capacity at low temperatures is nonsense because its storage performance objectively sucks (and not what it's designed to be good at)

It's like saying a Tesla is better than a 747 because it can go from 0-60 faster. A technically true statement but a meaningless performance comparison.

30-50% of my energy is the EV. About 20% is 120V plug loads (computers, fridges, home server), ~5-10% lighting, ~15% large equipment (dryer, electric range, electric water heater), and the remainder (15-30% seasonally) is HVAC (heat pump)

Any gas appliances would bring a lot of those numbers down

American House with an EV, all electric, and no solar, I use about 1200 kWh/mo (1.2 MWh/mo) on average. This could only carry me through about 3y. Even if I had access to good public infrastructure I think best I could do is 6y (again, all-electric home).

But I digress. Lithium ion as purely load shifting is a pretty reasonable, I'd argue critical, solution for covering day/night loads, but starts to fall apart completely when it comes to seasonal (summer/winter) loads.

But what makes this plant interesting is the addition of super capacitors. The combo battery/SC plant is less about day/night load shifting and more about providing stability to a shifting grid. As supply and demand grow increasingly decoupled, and we try and shift away from expensive peaker plants always on standby, systems like this can dramatically help smooth grid performance.

~90 MW of peaker capacity is small potatoes currently, but this is a big step towards a more reliable grid future.

Supercapacitors provide ultrafast response times – specified at 0.001 seconds – and maintain over 85% capacity at –40°C, significantly outperforming lithium-ion batteries in extreme cold.

Outperform how? At being a capacitor? That's their whole point.

On the energy side, 85% of 29 MW-min is 0.41 MWh. Even if the batteries lose 99% of their capacity at -40 °F, last I checked .42 MWh > 0.41 MWh.

These are two different tools for two different purposes, I'm not sure how you compare their "performance" under this metric.

Why "back" of course!! I hear babies got it, so start with them.

I'll run a backup and restore when moving to a new device, because why not. But regular backups? Meh, the ether can have my messages if my phone dies.

That said, depending on how this new system is rolled out, I may subscribe just to support the Signal foundation.

Frankly I love this, because now we get to watch the conservatives squirm.

Is Bill Clinton a pedo for associating with Epstein? Or are they going to walk back all of their statements and say Clinton did nothing wrong writing a sex trafficker a birthday card?

All the Democrats I know are fine with locking him up if evidence against him surfaces, but boy howdy is it gonna do a number on the conservatives in my life.

You do you - anything is technically possible, and from a purely engineering perspective a Steam Deck is an impressive little piece of hardware.

That said. I would advise against getting it for any sort of productivity. Having to haul out it, a separate keyboard, and mouse, just to take a quick note in class is cumbersome and distracting, even if we assume everything works on the first go every time (it won't.).

As others have pointed out, Linux is nice until it isn't - maybe you can partner up with a friend when your chemistry lab needs you to reference their archaic software to find some material property, but its a risk you're choosing to take on. Will it pair with the campus printers? What if you need to run Solid Works? Ansys? The drivers for a digital microscope? Collaborating on group projects in Microsoft Office (the web apps aren't the same.)? The list goes on.

Additionally, something like the Steam Deck is built for gaming. Meaning every time you pick it up, it reminds you it's time to game. As someone with ADHD who struggled to stay on task in college, having a constant reminder of distractions at my fingertips would have been overwhelming.

That's before we factor in the 'cool' factor of being that person in the class.

Get a laptop.

Except the video took 10 whole minutes to get there and probably wasted more than 2 sentences describing the problem.

I hate videos that could just be a 2-minute read.

Maybe, but I'm talking about this fuckerthat you would see at a restaurant:

Ghostly pink on the inside and full of air between thick crunchy dividers. It can fuck right off.

I still hate tomatoes...

...that aren't ripe heirloom tomatoes. You try to put an unripe, dried out, perfectly red and circular, bland slice of mass market tomato on my burger and I will RAAAGE.

Fair point! As far as I can tell, the temp sensors are just beacons - anyone can connect and see that somewhere in your house it's 72 °F, but who cares ¯(ツ)_/¯

If you're running on a Raspberry Pi, you can just use the onboard BT, whose drivers are updated regularly.

ZigBee ones get occasional updates automatically detected through HA, and have to be moved to somewhere near the controller to update. I assume, as temperature and humidity sensing hasn't changed, that these are security patches.

BT ones get no updates, which either means their security goes unpatched, or it really doesn't matter when all they do is shout out measurements into the void.

A couple of people mentioned sparkling water, and I want to join the train.

I got an off-brand sodastream. That and some Aarke flavor drops (https://aarke.us/collections/flavor-drops), and I have an infinite supply of la croix-esq bubble water.

I keep 2 bottles of (fridge-filtered) tap water in the fridge at all times and when I get the "I'm bored and don't know what else I want" pangs, I go there first.

I also generally try drinking more water, especially at the start of a meal, to push back against the tendency to over eat.

Finally there's the "just buy healthier snacks" but I struggle with that one the most

If i did mean to rape children, it's all of your faults their fault for "dressing that way" or whatever

FTFY. 100% think he'll go the "asking for it" route like most rapists.

Of course! From an end-user the experience between Bluetooth and ZigBee sensors is basically indistinguishable, except for range.

I have a detached garage, on the opposite end of my property from my HA controller, so the Bluetooth sensor out there specifically was a little flaky. The BT sensor is rated for ~160 ft but realistically it's 50-100 ft if your home has walls.

Swapping that one sensor to ZigBee so it could tie into my mesh network solved the problem. All other BT sensors have had zero issues, and their AA batteries unsurprisingly last longer than the 3R ZigBee AAAs, but both last at least 6mo.

Some Shelly devices can be used as "Bluetooth repeaters" but I'm unsure of the specifics of how that works.

If the screen isn't important, Third Reality makes a slightly cheaper version with no screen that also takes AAA - conveniently on sale now

I have a mix of those and an old version of these Govee Bluetooth sensors that are also fully offline, take AA batteries, and pair well with HA

Not strictly ZigBee, but cheaper, just as accurate as the 3R, and fully offline
