Little confused - I’ve been using fractional scaling on Wayland for 6 months now!

> Do you have a link to a fridge like that so I can imagine the concept better?

Large camping fridges are as close as I have seen, but I'm sure someone's thought of one for domestic use.

As for practicality in the kitchen, I can imagine a design where you have multiple medium sized fridge drawers. Once pulled out, you can open their top lid and access the content. This way, you don't have one deep container, but rather, multiple shallower containers. For efficiency, a single compressor can feed all of them.

EDIT: actually I've seen freezer drawers - you just need to dial the cooling down a bit.

Another idea: Vertically long rectangular compartments that can be pulled out individually. Essentially a whole bunch of vertical drawers of different sizes, with meshed walls to allow air to pass through them.

Another silly idea: a horizontally mounted ferris wheel

Fridges with top doors tend to lose lot less cool air when opened than the regular front door ones.

I suffer from hyperventilation syndrome and anything that brings my attention to my breathing (including wearing a mask) sets it off. I feel suffocated wearing a mask. I can get out of breath, have tachycardia, dizziness, chest pain if I wear it for a long time. And yet I wear my mask everywhere I'm asked to.

There is a big difference between feeling suffocated in your own home where no one else is involved vs. among people you could potentially be putting at risk.

> People wear a sweater all the time

I never do because I feel suffocated.

> see a doctor

Thanks for the unsolicited advice. I in fact have and have been told not to wear clothing that makes me feel suffocated.

> the burden of wearing a sweater is just incredible in some of these comments

Your lack of sympathy is equally incredible

Heat properly insulated spaces. I don’t want to walk around with piles of movement limiting and suffocating clothing inside my own living room. The problem is not what you heat up, it’s how well you insulate it from losing its heat. In Australia where I live, insulation is non-existent in the average home/apartment. Even simple things like tinted windows (for hot days), double pane windows and floating floor is missing. On the top of that, you have archaic HVAC systems that cool and heat from one vent and have useless thermostat feedback loops. A $30 hand rolled thermostats I put together for my fairly expensive apartment unit is infinitely superior to what came with the unit.

> You really have to separate your life from comments on hacker news.

Except, that's not how human brain works. You learn whatever you see often. That's why it's considered counterproductive to learn by bad examples. The common brain learns by repetition - it doesn't distinguish if what's being repeated is good or bad.

> Did a website really make you decide to be a dismissive jerk to your girlfriend and father?

You'd be surprised! If you're not influenced by regular behavior you encounter, then lucky you. Most of the rest of us do get influenced by simple things like the people's accents, to how they deal with anger and other emotions (e.g. learning passive aggression from a co-worker).

HN is no different than anywhere else. Majority of replies are hot headed, critical, cynical, and negative. You can have the most inspiring news, a huge innovation, big leaps in tech, great new products, and 95%+ of the comments are just sad to read, which leads me to believe that it's just human nature.

And no, critical thinking doesn't mean shitting all over everything you come in contact with, which is what most of us have apparently learnt from poorly taught college classes.

The minority of us "mutants" who get excited about things, should learn and continue to spread the positivity and hopefully move the dial towards the middle a bit.

And ye, this post is negative — I'm not a cartoon character in ecstasy state all the time.

Depends on location, I’ve never had a problem where I live and even in remote camp sites and on the highway.

When iPhone came out in mass production, its battery life sucked compared to the cheapest phone out there at the time (and still fires in comparison), it had connection drop outs all the time, didn’t allow the flexibility of most smartphones at the time and that’s just from top of my head. What it did have was a platform that had a huge potential for evolving well past the rest. If you don’t agree, go read the news articles and forums around that time (with posts just like yours).

Thus your point about rain sensors is moot - they run vision software to detect rain. It can improve essentially forever and at no expense to the customer.

Your ICE car may have a better rain sensor or auto headlight whatever now, but for a car that may be the most expensive investment, you will be stuck with whatever capability it came with, much like the feature phones of the 2000s.

No they don’t. If you insist, tell me which car does all those and does it like Tesla (recognizing all accents, works snappy, doesn’t require training, etc)

Ye, kind of baffled me too - it seems to use Google tech to recognize your voice which is almost perfect. Google assistant already does an amazing job with understanding natural language variations, I think Tesla is doing their own thing after getting the stream of words from Google.

It completely stops everything else playing. I think they need multiple microphones to do the signal separation (like Homepod and Google Home do) but I'm not sure if the car has multiple microphones inside (new Model S and X certainly do as they have active noise cancellation for outside noise).

> but in a car with lives at stake, they can’t be so cavalier

Oh man, my hair will go white soon if I have to tell people who keep making these kind of statements : either show this is causing accidents or lives with numbers or you’re talking out of your intuitive ass.

I agree with the rest - the new interface isn’t as intuitive and multiple interactions is required for various things that needed one tap before. It’s definitely worse and I hope it gets better.

What’s not intuitive to non-Tesla owners is that Tesla owners use the voice command extensively to get things done. Here’s a few of my day to day usage:

- Turn on recirculate

- Lower the temperature

- Play song X by Y

- Navigate to supermarket

- Fold the mirrors (for when parking in tight spots)

- Turn wiper high (no longer use this as the auto setting is almost perfect as of late)

You initiate the voice command by pressing a physical button on the steering wheel under your thumb. For majority of what I’ve listed above, you’d have to take your eyes off the road to either operate a physical button or tap on awfully unresponsive touchscreens in other cars. So as far as I’m concerned, I’m more road alert in Tesla than I’ve been in any other car. Add autopilot in the mix and nothing else comes close.

And to add to that: you should use as many different symmetric keys as possible as long as asymmetric decryption of the key doesn't overly degrade performance.

> they will only investigate if they "see a trend".

That's your answer right there. It's awful what's happened to you and your car but if this issue affects one in XXX (some large number) customers, it doesn't warrant the NHSTA's time which I'm sure has a large existing backlog of issues to investigate.

In this particular case, not much. They are expanding their factory in California. They are not moving all their operations.

to move towards a sustainable future, he's moving on to Texas. Hell of a great use of subsidies.

If you’re truly interested to know the answer to this, you can find it aplenty online. And it’s not because it’s “sexy”.

Lots of misconceptions about how power delivery works over USB-C. Here are a few facts that may help:

- USB-C power is negotiated over USB-PD protocol. Dumb devices are going to get 5v at low max. current.

- The sink device (laptop) must communicate and specifically ask for voltage/current it needs. Sources (power supply) aren't going to just push the max voltage to any device.

- All USB-C cables are required to support 3A of current. For any higher current, the cable must have a chip that advertises its current capabilities.

- The new spec imposes further requirement for the cable (in form of extra capability advertised by the chip in the cable). Power supplies will only enable 50v if such a cable is present.
