If the car charges the house battery, what charges the car?
irons · 5 months ago
If you have solar panels or time-of-use electrical rates, you charge the car when power is cheap/free, and spend stored power when the grid costs are high. During a protracted outage, maybe you drive the car to a fast charger.

Personally speaking, having just bought an Ioniq 5 and installing solar at home what I see as the near future improvement is adding V2L functionality, which I can hook up to the generator input of my solar inverter, essentially adding another 60kWh buffer to my grid storage.

Considering how expensive residential batteries are and how quickly EVs depreciate, I think soon it'll be cheaper to get a used EV as a cheap source of cells that accidentally happens to be able to drive itself around.

Imo V2G, and V2H is unnecessary and add too much complication, I think for the future, solar inverters already have the necessary hardware and certifications to be able to take power and safely connect to the grid - something that requires different hardware and standards compliance in basically every country (yes even within the EU).

In the US, V2L limits your ability to output power from the car to about 1500 W. It's not going to power your house as more than a stopgap, even if you do have supplementary house batteries. V2H/V2G justify their complexity by solving that problem, along with all the ancillary grid benefits.

I feel like this review needs a huge amount of context on PTA and his previous films to create any sort of justification for this film. That... that does not seem like a good movie to me.

This is the January 2024 ruling allowing Apple to resume imports of Apple Watches to the US with the blood oxygen feature disabled. Hopefully the recent ruling will show up on this site at some point.

Yeah, the secret of a good ice cream is the egg and cream custard, and churning while it freezes. Which does make it a bit of a pain, but well worth it.
irons · a year ago
My go-to ice cream book is Jeni Britton-Bauer's https://jenis.com/products/jenis-splendid-ice-creams-at-home (which won a James Beard award), and her base for all but a few custard recipes is milk, cream, sugar, starch, and cream cheese. I love eggs, but they are not a required element of top-shelf ice cream.

> Wishful thinking, but next up should be homeopathic snake-oil.

It sounds like it's serving a useful purpose.

> "I know so many people… hell, I've done this myself, I've bought [a homeopathic] product by mistake," Little said. In a trip to the drug store while sick or as a weary parent of a miserably ill child, it's easy to mistakenly pick up a homeopathic product in haste or the fog of infection.

If folks are going to irresponsibly take some random drug without having any idea what's in it, it sounds like funneling them toward something that won't harm them is a good thing. I mean would you really rather have them giving their kids something like tylenol without reading the dosage instructions?

If you're assuming that the homeopathic stuff is incapable of harming anyone, you're mistaken. https://arstechnica.com/health/2023/08/fda-warns-amazon-to-s...

"Neutral", maybe, but their stance goes beyond neutral. They clearly position themselves as "infrastructure". HNers should appreciate this more, as it's often a recurring theme here to talk about ISPs as infrastructure.

Infrastructure doesn't privately discriminate, period. Water/Electricity utilities don't cut the supply to rapists and terrorists just because they're rapists and terrorists. They cut it when law enforcement ask them to.

This conflicting discussion is better had on this level: "Should Cloudflare be considered infrastructure, or not?". It's not straightforward.

irons · 4 years ago
If rapists and terrorists used their water or electrical service as a primary means to rape and terrorize, then those infrastructure services would find themselves feeling justified pressure to develop terms of service prohibiting that conduct, and to cut off the rapists and terrorists who violated those terms.

"Infrastructure" has the luxury of being value-neutral. Cloudflare wishes that were also true of it, frequently and publicly, to no avail.

BeefySwain · 4 years ago
Can someone summarize how this compares to how things were prior (if there is even any change at all)? Does this make it easier or harder to sideload apps, for instance?
irons · 4 years ago
Previously, each developer had to do one or more of:

* use TestFlight for centralized distribution of pre-release apps, through Apple (with some lighter-touch app review involved), or

* use enterprise signing (which requires enrolling in a more expensive program and jumping through some corporate hoops, with your apps subject to deactivation if you abuse it) to install on an unrestricted number of devices theoretically owned by your company, or

* whitelist a pretty low number of specific iOS devices to install arbitrary apps onto — I think that limit is still 100 devices per year, per developer account

This sounds like it removes the whitelisting requirement from the third option. Hope it's enough friction to prevent the worst aspects of sideloading from taking hold.

I wonder how many others also have such strong negative reactions to this sort of mass destruction. It is hard to explain the feeling, but regardless of the product or manufacturer, seeing something which most certainly took a lot of effort to design and create brutally pulverised almost makes me want to cry.

On the other hand, maybe a lot of other people love seeing things destroyed, as evidenced by the popularity of shredder videos on YouTube, or maybe it's interesting in the same way as car crashes and other disasters.

The article's conflation of things being broken down into their component parts and recycled, vs things being "destroyed", is maddening and tendentious. Try not to fall for it.

Let's encrypt looks so cool with its very few steps. But then you install and you get all sorts of errors not me toned on the page. I spent a good 5 hours debugging yesterday.

When it finally works I see that the certificate expires in 2 months.
