If I recall correctly, ethanol needed to be added at around a 10% level to prevent engine knocking. At its peak, lead was present at around 1.1 grams per gallon, so about 0.1%.

Not intended to excuse them. The amount of additive required was why leaded gas was cheaper than using ethanol. And as a reason, three generations grew up with lead poisoning.

MIDI was designed as a way to link up a controller like a piano keyboard to a synthesizer and transmit the notes being played. In that area it's certainly not obsolete: synthesizers still transmit and receive MIDI messages and sequencer software still records them. It's the only sane way to edit and view note data because you can't edit audio easily to change a few notes.

As a way of transmitting musical scores it's obsolete, but mostly because it was really hard to get MIDI soundtracks to sound as intended because there were so many different synthesizer implementations.
I don't think a balloon would fly erratically if the air was released in space or a vacuum. As far as I can understand it, the air would rush to equilibrium in all directions - the balloon would deflate rapidly - but the air 'movement' would not move the balloon, as in a vacuum there is nothing to push against. Any erratic movement would be due to the elastic of the balloon returning to its resting state. I think you would also get movement in earth based vacuum chambers due to gravity.

The presence of this and other telling symptoms suggests that you may have a thiamine insufficiency. Alcohol is a powerful inhibitor of thiamine. This is why when alcohol is consumed it causes exacerbation of symptoms.

Please note that B1 (thiamine) deficiency is a dynamic thing. A healthy individual needs a very specific amount, but a compromised individual may need up to 1000x of thiamine RDA dose to overcome the pathology after its onset.

Right. But “lol, we’ll just get rid of moderation, bro” is an incredibly naive and dangerous non-solution.

So far all I’ve read are vague claims of oppression. I do sympathise that you don’t feel happy about something. Life can be a struggle and nearly everyone has their share of challenges. But based on what you have written so far I’m very unconvinced it’s anything much to do with western life because a) it’s terribly vague and b) sounds very familiar to stuff I’ve heard before from people just wanting to blame others for their own problems. I’m listening though so be specific and I’ll genuinely consider anything you have to say.

Not quite the same but when we were rebuilding during COVID we knew we wanted two good WFH spaces but really only had room for one (tiny) office - as our second we built a shelf in our bedroom wardrobe that lifts up to reveal a work surface and a 32" monitor - inspired by this guy's work on ikeahackers:

https://ikeahackers.net/2020/10/fold-out-desk-home-office-pa...

Works really well and given the cost of space for a second desk it was a very cost effective solution - only minimally affects the utility of the wardrobe as a wardrobe. (We didn't build the laptop holder this guy describes, the laptop just gets sat on top of the clothes in the drawer below that shelf with attention to make sure we're not blocking a fan intake. We had a powerpoint and a ethernet port put into the back of the wardrobe but actually we just end up using Wi-Fi mostly.)

For bandwidth intensive usage such as video, it will probably be "paid relays" instead of free ones. Click on url in the "Popular paid relays" paragraph to see examples:

You send a photon with the polarization giving the bit:

Basis +: | = 0, — = 1,

Basis x: / = 0, \ = 1

You randomly choose a basis for each photon, but don't tell the receiver which basis it is until they receive the photon. They randomly choose a basis to decode on, and once learning the correct one discard the bit if they mismatch.

The key thing is an eavesdropper wouldn't know the correct basis either. If they try to "pass along the photon" they'll re-encode it in the wrong basis half the time, so the receiver will end up with the wrong bit when it should be correct (25% of the time). The sender can share some of the correct bits, and if the receiver has too many errors it's likely someone is eavesdropping.

Now, what bits do you actually send? Probably something like a "Learning With Errors" (LWE) cryptography key (as quantum computers kill RSA). Then you can transfer your actually data over classical communications. The quantum part is just the handshake at the beginning. If you detect eavesdropping you just send a new key over.

The current limitations are:

1. It's really slow. It can take seconds to send a 1,000 bit key just 1km (figure 4, 10.1109/PHOTONICS49561.2019.00010).

2. You need a single photon source so the eavesdropper cannot pass along photons while reading the message. It also has to be "heralded", i.e. you need to know when that photon gets sent. Right now these are pretty slow to generate.

3. The error rate has to be really low, otherwise you can't detect eavesdropping.

4. Your detection system can't have backscattering/other side-channel attacks. To detect single photons, people usually use "avalanche detectors", where the photon excites an electron, which goes on to excite many more due to a potential difference in a p-n junction. However this also creates small flashes every time a photon hits it.
I love that nostr identity is not tied to an instance (unlike activitypub/mastondon/fediverse)! However ignoring some (IMO) fundamental problems (because they are not problems until you hit scale) like hosting, somewhat moderation and letting that be solved "layer above" is a mistake (IMO) it will probably create non standardized APIs for paying for hosting or sth.

As for community it is heavily based on bitcoin/lightning enthusiasts and a lot of content revolving just around that - probably won't attract people outside the circle/general public (which may not be the goal or preferable outcome!)

You can also control what people can't see on nostr, by simply rejecting/deleting any messages from relays or ids you don't like. This isn't a big problem for something like plain text because it's cheap to run a relay that only stores text but if you're letting people upload/download video... That gets expensive fast.

I'm not sure why you're getting downvoted here. In any other context, "paste in the private key that your identity is irrevocably bound to" would get you laughed out of the room. It seems to be the default nostr UX nonetheless, and that's worthy of note.

Agree that there are things we don't want to exist, but by your logic internet should have been forbidden a long time ago.

This can be said for so many situations:

Most people does not want cars to crash into Christmas fairs either.

But the solution is not to ban cars.

Most people does not want kids to be bullied at school.

But the solution is not to ban schools.

Etc.

You can say we have laws about cars. Yes, but those laws aren't enforced by Ford or Volkswagen. Edit: or by Shell or Exxon for that matter.

There will be laws about content on internet even if Google can't willy nilly remove the channel of Warthog Defense because it hurt some russians feelings.
Yeah - there's even some fairly capable "cloners" available on eBay for most of the common formats. I guess that the ongoing use of (derived from magnetic stripe) Wiegand interfaces mean that most can be cloned like this.

There are absolutely some unclonable (without massive expenditure on defeating CC EAL 5+ smartcards) access control systems, but those are never the cheapest, so they don't get adopted outside of (very) high security environments.

I wondered if we'd see a shift once the Flipper Zero hit the ground, but it's probably still a bit too early on that.

A lot of hotels used to use insecure (and pretty easily cloned with an Android app) Mifare Ultralight NFC on room keys, but I've not seen one of those recently - most seem to be Mifare classic now, which is secure if your keys aren't compromised.
Maybe there used to be one and was later removed? There's no doubt some kind of indexing, so the data may become stale.
I think we're largely agreeing, but a fundamental difference is that actual debt you have to pay back, and with technical debt you don't. So inherently you need to start discussing the trade-offs associated with the debt, and not the actual "debt" itself. Technical debt is not some external thing that we are forced to deal with.
Android is a Google project through and through, so I'm not sure if basing the result would actually be "reducing google hold on european market". For that you'd have to actually have a product that isn't developed by one of those corps.

I was nine in 1984 and had a BBC B for my 9th birthday earlier that year. Later I modded it with the speech ROM chip docked in the left hand panel open slot.

That boot up noise brings back a lot of memories, as did the 5-10 minutes waiting for the cassette tape to load the games.

I had to wait for my next birthday to get my hands on Elite, spending my time with Meteors and Kingdom and other games that I can no longer remember. Apart from dipping into games like Repton for my siblings, Elite became the game I played religiously, often late in the night without my parents knowledge, and giving up my TV rights to watch the A-Team and Knight Rider (but not Battlestar Galactica) — determined to reach Elite status.

I became extremely proficient at trading slaves, drugs and people, and dogfighting with the police vipers and bounty hunting pirates. I amazed my friends how quickly I could dock, since for newbies it was extremely hard to get the right roll and trajectory until it finally “clicked”. A proficiency in hand-eye coordination in 3D space.

I managed to complete it some three years later. It’s one of the few games I’ve actually ever “finished”, not that you could ever really finish Elite.

This machine was what started me on my path to where I am today. Later I added a Commodore 64 to my collection, and the poor old Beeb was relegated to the attic and finally given to someone else by my parents, but that mottled cream tin box shell with its mechanical keyboard will always have a place in my heart. I also remember it being very heavy, but I was a nine year old child.

I achieved Elite status and nobody can take that away from this nearly 50 year old geek. Sometimes I'm tempted to put that on my CV as a conversation starter.
If I wanted to be controversial I'd say that most recurring meetings and any meeting with more than 5 people are a waste of time.

You're probably right but it's sad that this is regarded as controversial rather than self-evident. Maybe any meeting with more than 5 people being a waste of time is a stretch and most again would have been a more defensible claim? But the spirit is right. Good meetings happen when there is a good reason to have a meeting. Recurring meetings are often symptoms of other management problems that have better solutions available.
Interesting. There's a similar library called PhlexUI, also in pre-release. https://phlexui.com/
> Self-driving is very easy to evaluate.

I disagree. We can say that someone is driving safely in one given moment. A drunk driver could drive quite safely through a main road while we watch them, and then turn around a corner and run over someone the moment they leave our sight. We can only extrapolate the "goodness" of a driver by expanding the time we spend observing their driving. 2-3 hours of evaluation will be quite solid. It would be even more solid if we are inside the car with the driver, and if we have received training about how to evaluate a driver. And the result would be even more reliable if the evaluator is financially independent from the driver. And for safety, the car should have controls that allow the examinator to take over if needed.

So yeah, I am describing a driving test. As far as I know we don't have those for self-driving cars. We should.

They should be way more thorough than than the ones we give to a human, because machines lack the shared context that humans have with each other. Tests like driving offroad, driving while there's tiny (fake) animals around, behavior in a (staged) accident, etc. Things that we know a human will have enough context to deal with, but for a machine it's not a given.

One advantage is that these tests could be done in parallel. You can load the same AI in 50 identical vehicles and have 50 examinators run tests on it at the same time.

Unfortunately it is the opposite for me. My children are five and two and these have been the worst years of my life. I never knew unhappiness like this before. I've had depression since a few months after the birth of our first child. He has adhd and autism and has been extremely challenging. I should have known better, as a childhood adhd sufferer (on medication for most of school age), known that I probably wasn't a good fit to be a parent.

I have realised too late that my coping mechanism for dealing with the complexities of the world is retreating to a safe space when I need to. That usually involves getting away from everyone and playing a computer game for a few hours, or going for a long hike, or just driving somewhere to be by myself. And it needs to be frequent.

I cannot do that any longer. Our kids are so challenging that leaving one partner to cope by themselves is too hard. I never get to escape and I find it bordering on impossible to deal with the world. I have been suicidal at times. I'm on medication for it.
