nick_kline··on Robin Williams suffered with undiagnosed Lewy body dementia before suicide
Thanks for posting that. I wonder if some people I've known who passed with kind of unknown cause dementia passed away had it. "Lewy body dementia" is a confusing term on its own, I was guessing that it meant some kind of body confusion thing, instead of growths (bodies) in the brain. https://en.wikipedia.org/wiki/Lewy_body_dementias
nick_kline··on No, SAR Can't See Through Buildings
Reading that long article where the writer didn't have awareness that they should define that term reminds me of reading in grad school. Please define the main term in your articles, people! Geeze.
nick_kline··on 2020 United States Postal Service Crisis
He is significantly damaging the normal operation of the usps by his actions, regardless of intent.
nick_kline··on 9k-Year-Old Stonehenge-Like Structure Found Under Lake Michigan
This is a separate site that doesn't have rocks from the famous UK stonehenge. The idea is it might be independently created, as a natural thing people might make to track things like the sun or other astronomical movements (like the movement of the sun at the solstices). And if the age is about 9,000 years old, a little older than the uk stonehenge.
nick_kline··on Linus Torvalds on the new MacBook Air
Chromebooks are often a nice, relatively inexpensive and hackable x86 or arm device, but there's nothing that interesting about their hardware other than not so locked down (there's dev mode allowing anything and you can overwrite the firmware even). The new apple arm has fascinatingly good performance, and long battery life and the Air has no fan, so there's a lot to like there.

I don't work at Gaia platform any more, I have no influence on them, but they should observe good behavior toward their customers like anyone.
nick_kline··on Tunnels in the US cost more than anywhere else
And increasing the construction speed is the major thing we need to do here! Otherwise many of us working in seattle from outside will be retired or dead by the time it gets to us. I'm very eager to spend more of my own tax money to construct the system faster. Plus we should do it before Tim Eyman eventually takes away our ability to tax ourselves.
nick_kline··on “Before cancelling your subscription, you must agree to the following”
Terms of service that hurt the end user are a bad idea, unacceptable, like dark patterns that cause people to opt in to things they don't want. It's not a crime, but it's immoral.
nick_kline··on Ask HN: Is an unusual keyboard layout a problem when interviewing?
Just bring your own keyboard. Unless it's in a super high security area, no one will care.
nick_kline··on My 21km P2P ubiquiti link
This is a nice read if you ever were interested in wireless backhaul. He really goes 21km through line of sight, 3ms latency, 80u/70down (other side was family member's 1gbit).

Sends his legal wireless signal across a tiny. border toofrance/switzerland/france

nick_kline··on Lost Languages Discovered in One of the World’s Oldest Libraries (2017)
Danh, yeah, got that wrong, not sure why dead went to red, thanks for the fix.
nick_kline··on Lost Languages Discovered in One of the World’s Oldest Libraries (2017)
I love reading about newly discovered works from the ancients. I'm really hoping some of the missing plays and history and math shows up here. There are also those burned red sea scrolls, I hope later tech can read them.
nick_kline··on Google could make Chromebooks last years longer with a change to Chrome OS
Today they update everything until the end of life. Google has made no announcement about extending life with only browser updates - that would be great but I'd be surprised. They could just use this change to make faster updates by separating the browser and OS, that's the obvious thing.

It would be really great for google to extend support and make the browser updateable later - the browser must be the vast majority of attacks. I think they have to keep old hardware around and they want to use more power, it's hard to keep things working on weaker, older systems.

My guess is google doesn't add chrome-only updates to existing end-of-lifed units, it will only be for new ones. But I hope I'm wrong.

nick_kline··on 'Wild West' mentality lingers in modern populations of US mountain regions
Don't forget the very first settlers were native american people as we call them today in the us. It's interesting to think about their views of today's self-reliance culture. I don't know what they are.
nick_kline··on A Superspreading Event: The Sturgis Motorcycle Rally and Covid-19 [pdf]
As others have said, there are unknown but already detected cases of asymptomatic impacts. One football team doc said he thought 1/8 had some impact on heart function long term. Those who see this as no big deal for some reason are stuck on arguing the exact percentage of impact.
nick_kline··on Escape from Creek Fire
Probably getting sick was a combination of exhaustion, breathing smoke and anxiety.
nick_kline··on Escape from Creek Fire
That seems unfair. When I've been backpacking, there is not much info about anything like a sudden fire that could move randomly around you. That could easily kill you. Even with help there were 200+ people who were surrounded by fire. There weren't a lot of extra resources to help a small group.
nick_kline··on Show HN: Base32H, a human-friendly duotrigesimal number system
Use the us ascii 0-9 and a-z (caps equivalent). O and zero (0) are the same, as are numeral 1 and L and I. S matches a and 5.

I like it.

Religious people pine for any proof of consciousness being something other than a mechanical thing in our body but all availableinformation points to there being no magic.
nick_kline··on Withings' ScanWatch packs ECG and SpO2 sensors alongside the usual tools
The question for everyone else than apple is what will the likely imminent next gen apple apple watch have on it and what will it cost, etc. The market isn't quite owned by apple & Garmin...) but it feels closer every cycle.
nick_kline··on Your mind will not be uploaded (2014)
If you can handle 25k neurons today that's roughly 19 binary orders of magnitude to 10 billion or less than 38 years of Moore's law type doubling, calling it 2 years instead of 18 months per double. So not that scary. There are different kinds of doubling and who knows if it will keep on keeping on.
nick_kline··on Your mind will not be uploaded (2014)
It's not immaterial at all. It's basically the same thing as going to sleep at night and waking up or seeing your friend after a 1 minute break. It can feel like the person who was gone had continuity.

Great point, need to consider that in my will. Every mini me can have 5% of my estate, up to 60% of my estate being consumed.
nick_kline··on ReMarkable 2.0 – A digital notebook that feels like paper
That seems naive. Very few products succeed without marketing. Only tesla, for example, in autos succeeds without much marketing. I'd never have heard about remarkable2 without current marketing around the v2.
nick_kline··on Lucid Air EV’s Battery Will Be 113.0 KWh
Then why does every company say that they have production limitations based on availability? VW was saying that just a few months ago, and so was porsche. That's give as the reason why Audi and Jaguar have low volumes.
nick_kline··on Apple to start requiring written consent for third party API usage in apps
That's correct, the drivetrain is completely separate from what you can access from the outside.
nick_kline··on Apple to start requiring written consent for third party API usage in apps
It's not driving it. It's controlling the entertainment system, which includes things like AC/heater, charging or not (you have to be plugged in), closing or cracking the sunroof, looking at the state of charge. You can also unlock the doors. You have to get an otp token based on your name and password. People reverse engineered the tesla api from looking at what the app does. There are two concerns I have with the tesla system.

1. They only allow for tokens that take a very long time to expire, it's something like 3 months.

2. Although a few of these apps allow you to get the token on your own and send it to them (thus not exposing your password), that's too technically demanding for most users and so most of the apps have you get a token by giving your email/password, thus you expose it to them.

For those that don't know, Tesla pays people for security vulnerabilities, welcomes hacker attempts, they disclose things after they fix them, there's a list of the things and people who found them at their website, etc. There is a separate computer system for the drive train that is not accessible through this system.

nick_kline··on Lucid Air EV’s Battery Will Be 113.0 KWh
There's no magic required here, people. Batteries, engines, just tiny changes on existing Teslas. This car is dooable by Tesla and by third parties like Lucid Air just replicating some of the things Tesla has done and making small improvements.

1. Battery capacity: Tesla had 100kw cars 4 years ago. 13% increase - easy, even within Tesla's grasp, they just have not bothered.

2. Efficiency and range - this is just a small improvement on what the Tesla model S has, add more batteries. The Lucid Air is bigger than a model 3 and closer to an S. The S already has 400 miles. Tesla improved on the original 2012 (yes, those are 8 years old!) model S' range by using the more efficient model 3 engines on the S. The S has 100kwh currently.

3. The model 3 has different batteries than the S, apparently they have a bit higher capacity in the 3 than in the S. All Tesla has to do to give the S another boost is switch to using the model 3 batteries, add a few more. The one downside of the 3 batteries is supposed to be they have less max power, so less acceleration? Tesla is going to have 'battery day' soon when they will talk about their next generation batteries, and perhaps talk about S improvements.

4. Manufacturing, and especially getting enough batteries - this is where Tesla is likely really ahead. It's hard to make cars in volume, even expensive ones. But getting enough batteries for a large fleet of cars is the early 21st century unobtanium. Every other car company that ones to make large volume EVs can't do it. Where everyone is at least Japan and Europe and the US. China might be able to pull this off, too soon to say.

nick_kline··on Boom Supersonic hopes to test-fly its supersonic plane in 2021
Wow, I hadn't heard about that. If they were 1 or 2 years quicker they might have been out in the market before the pandemic presumably killed them?
nick_kline··on Boom Supersonic hopes to test-fly its supersonic plane in 2021
It's interesting to speculate about what a ticket might cost and what would be worth it to you. Instead of a non-stop almost 10 hour flight to west coast to London at $1,000 (9:20 hours), where my company gives me an extra $500 for an upgrade in class because it's so long, I'd pay an extra $500 of my own money for a 4 or 5 hour trip probably. But I'm not paying $5k more for that quicker trip.
