Gives them a pretense to give money to the weapons industry -> weapons industry has higher profit -> stock goes up -> Dow Jones is over 50k, which makes their other crimes legal.
- Comment on Motorola confirms GrapheneOS support for a future phone, bringing over features 2 days ago:
theoretically you should be right but there’s software hidden in the hardware that you can’t uninstall or modify that could (hypothetically) be surveilling you. like in the networking equipment that’s inside the phone.
realistically, i think the chances for that happening are actually very low, also because the networking firmware could only see your encrypted data packets, but it could still figure out the IP addresses that you communicate with. i’d rate it a none/low risk level.

it’s cheap. mine was like $200 new. can recommend.
- Comment on Motorola confirms GrapheneOS support for a future phone, bringing over features 2 days ago:
I actually bought a new Motorola phone 2 months ago precisely because i wanted a phone with an unlockable bootloader, and motorola delivered that.

About the golf meetings:
I made up a story around it. Basically, golf is a metaphor for business. You gotta get the ball (yourself) into the hole (your target). Sometimes, you can’t do it in one step, so you require multiple steps to approach your goal. In any case, you take big steps in the beginning, and then as you get closer you need to become more gentle and delicate to not miss the perfect spot.

I keep thinking that your lower back hurts for psychological reasons. Like, tummy ache is caused by psychological reasons like 90% of the time. It makes sense that the same would apply to back aching, since they’re in the same region.

Also the internet makes money mostly with ads, which is a way to manipulate people’s opinions on things.

I find it helps to raise your hand in front of the screen to block the ads when they start playing. It’s like a middle finger to the advertisement companies.

yeah i guess it depends on the time frame that you look at things. I was only considering the next 1-3 years.
- Comment on The Physics of Data Centers in Space 6 days ago:
The price is dropping but not that rapidly. IIRC the price dropped like 95% over the last 25 years … That’s a 12% reduction annually on average. Compare that to computer chips where prices dropped 60% annually IIRC and solar panels where it dropped 30% annually.

This also reminds me of something else: Yes, you can have all kinds of problems in space missions. Not just bit flips.
I have been thinking about planning a mars mission. And one of the things that you need to guarantee is the safety of the crew in untested environments. Like on the surface of mars, you have to guarantee that the crew can survive at least until the next ship can arrive to help them. And launch windows to mars appear only once every two earth years (once every martian year), so crew has to survive that long.
You also have to survive when there’s a power outage for any reason. Could be that the coworker stumbled over a cable and pulled out a power line’s connection. Could be that there’s 3-months-long dust storms (which would block solar panels). (they appear each martian year, sometimes more sometimes less severe, i think typical duration is less than 50 days, but just to be sure make that 100 days). Could be that there’s a problem with your electronics and they simply won’t work anymore and you can’t figure out why.
So imagine you’re standing in your apartment. I recommend you live inside the Starship for the first few years because it’s already a habutat since you flew in it for 6 months to get to mars in the first place.
Power outage. How do you get out of the door? There’s obviously a pressure door between your apartment and the outside world. And the power line’s outside. So if the power line disconnects because a rover messed up and pulled it out, there’s a power outage. And if the door is electrically operable, you can’t get out of the door to repair it. That is why i say that every door has to be manually operable. Like, pressure doors should have manual operation mode. You need to be able to operate the pressure door with your bare hands. I already thought of some designs that can actually deliver that, but i’m too lazy to do a drawing now.
- Comment on The Physics of Data Centers in Space 1 week ago:
Like, very interesting article. It also mentions bit flips.
I think the major protection against bit flips is to use larger structure sizes. Like, today’s desktop computers use structure sizes around 2 nm or sometimes even less than that. Which means you only need to shift a few electrons around to cause a bit flip. If you use larger wires inside the processor, they store more electrons so it takes more energy to flip them around. So there’s a much much smaller number of radiation particles that have a minimum of that energy, so lower risk of bit flips.
Does anybody have actual numbers on the structure sizes needed to effectively prevent bit flips? I mean, outer space missions like NASA flights already need this today.

You know how much it costs to transport stuff into space? Well, currently, around $1k/kg of material. Let that sink in.

- Comment on Singing is just talking with more tone variations. 1 week ago:
Nope. there’s three domains that are typically distinguished: the biochemical, mechanical, and neural level.
You wouldn’t call a thinking process a “motor activity” since the ideal neural net has practically no moving parts, similar to an ideal computing machine.
- Comment on Singing is just talking with more tone variations. 1 week ago:
No i think there’s also rhythm to it.
Fun fact: Many people who stutter can sing just fine.
I attribute it to the fact that music enforces a certain rhythm and that makes you move on with your speech more fluently than you would otherwise do.
- Comment on Can a reasonable person genuinely believe in ghosts? 1 week ago:
IMHO “ghosts” is just an older word vor virus.
People in earlier times knew that some diseases jumped around from person to person and that that could be dangerous, but didn’t have a proper explanation for it.
So they assumed that there must be something invisible in the air that creates the kind of spooky effect that people fall ill sometimes without being touched or physically hit in any way. Kinda spooky, if you think about it and only know about mechanics, but not about cellular biology.
- Comment on Europe is ready to ditch US tech for private alternatives 2 weeks ago:
yes, german has a very weird way of writing numbers, where . is replaced by , and , is replaced by .
So, in US numbers, that would be EUR 274,091,361.75
It has confused many people already. It should be made more consistent internationally. I propose all use the US format of 274091361.75 because that’s already used in programming and so it’s widespread.
- Comment on Europe is ready to ditch US tech for private alternatives 2 weeks ago:
To give a bit of technical details, the hardware must have a feature to destroy encryption keys for user data whenever a new OS is installed on it; and you have to be able to install a new OS on it at all.
Like, today, many smartphones have the problem that you can’t install a new OS on them at all, because the bootloader doesn’t allow it. Meanwhile PCs have a different problem, where they do allow installing new OS, but the user data is typically not encrypted and so you can just boot linux from a USB device and read all contents on the internal disk.
The best solution might be to encrypt all userdata, store the keys in the bootloader on the device, but when a new OS is loaded/installed, the bootloader doesn’t give out the keys so the userdata can’t be decrypted.
