Boiled linseed oil is because the additives make it look like boiling - this contradicts the article but I believe the article is wrong. One of the traditional additives was lead, but even the modern lead free versions are not all that safe for food unless the manufacture claims otherwise (most don't)

You can still get actual "proper" double boiled linseed oil. It's not even especially expensive, just mildly annoying to source. It's a surprisingly durable finish for outdoor furniture etc, just takes an age to cure compared to the chemically boiled linseed oil.

It would. Currently they and everyone else are getting deeply fucked because the signal to noise ratio on the internet has been obliterated and everyone is being manipulated all the time by misinformation from humans lying to bots.

I think the trade off for a lack of anonymity is worth it. This is crass and old but the penny arcade guys identified this decades ago

I agree misinformation is a big problem. Possibly the biggest problem of our time, right next to global warming. But as it stands now, as a queer person, you can find a spot on the internet with like-minded people. Even when closeted. Hell when closeted it's the only place you can find like-minded people.

If we require people identify themselves online you drive all closeted queer people away, into solitude, into feeling no one will ever understand them. That's not worth the price of admission.

We need a better solution than that.

Everyone keeps making religious connections, but it’s worth pointing out linguistically most countries in Europe (and the world) refer to red meat, poultry, and seafood as entirely separate. Meat often just refers to red meat. English is in the minority to bucket them all under “meat”

Not to mention that loads of people detour through pescetarianism on their way to vegetarianism. But even if you stop at pescetarianism that's still a wild improvement on plenty of metrics over eating other meats.

There seems to be this pressure to either go fully vegetarian or it doesn't count, which is obviously total nonsense.

Hard disagree on anonymous speech. Individual humans should have free speech but that is divorced from anonymous speech.

With anonymous speech you don’t even know if you’re talking to a person or a program.

If you want to say something, then say it with your identity. You don’t get to be anonymous when saying something to my face so why should it be allowed across a screen?

Doxin · 4 days ago

While what you're saying sounds like a reasonable enough stance on the face of it, keep in mind that this would deeply fuck over closeted queer folks among other marginalized groups.

So what grocery stores used to be ~90 years ago, when the norm was you would give the clerk a list and they would grab your items from the back? The only stores I'm still aware of that are setup like this are auto parts stores, where 90% of the inventory is in the back.

Toolstation still has a model like that, and I gotta say I love it. They also seem to hire people who actually know something about the products they sell which is an unfortunate rarity these days.

You don't need to be able to mathematically jerk the equation off to understand why increasing material at the perimeter adds more strength than the center (within reason and in typical cases) or why you probably shouldn't use something that melts around 200deg in an engine bay.

Doxin · 7 days ago

Note that the actual material used has a glass transition temperature around 50 degrees, not 200. If the part was actually made from ABS-CF (as the pilot thought it was) it'd stand a decent chance of surviving for a long time given that it gets a lot of air cooling.

It sounds like it was something like PLA when it was supposed to be ABS.

According to https://assets.publishing.service.gov.uk/media/69297a4e345e3...

> The aircraft owner [...] understood from the vendor that it was printed from CF-ABS (carbon fibre – acrylonitrile butadiene styrene) filament material, with a glass transition temperature of 105°C [...] he was satisfied the component was fit for use in this application when it was installed.

> [...] Two samples from the air induction elbow were subjected to testing, [...] The measured glass transition temperature for the first sample was 52.8°C, and 54.0°C for the second sample.

I've known 3D printing folks who run off a throwaway prototype in a cheap, easy-to-print material to check for fit before printing in more difficult, expensive materials. Easy to imagine a careless manufacturer getting the PLA prototype mixed in with the ABS production parts, and selling it by mistake.

Of course, the aviation industry usually steers clear of careless manufactures....

You'd be very hard pressed to confuse PLA with carbon fiber reinforced ABS. The latter has a definite surface texture that's hard to get confused with that of PLA.

> I really want to know though, what is all that data!? Textures?

Yeah.

A single 4096x4096 texture is 16 megapixels. At 8 bits per channel with potentially 4 channels, that's 64 MB for a single texture uncompressed.

Doxin · 10 days ago

But who in their right mind is storing textures uncompressed? and that still fits over two thousand 4k textures in a 130GiB game. Are there really that many things you'd look at close enough to fill a whole screen in a game?

Imagine how much unnecessary time would be added to a course about series if the lecturer had to write sum() instead of ∑ every time. If you find it hard to remember that ∑ means sum, math might not be for you, and that’s fine.

Doxin · 10 days ago

it's not so much remembering what ∑ means insomuch as that it's completely impossible to google the first time you run across it. It'll be in some PDF that doesn't allow you to copy-paste the symbol and you won't know what it's called. Rinse and repeat for any of the million symbols mathematicians use, never mind that loads of symbols are context dependent even if you could google them.

I hope mathematicians have a better reason than "it's tradition" for making the entire field completely opaque to anyone who hasn't studied math extensively.

Many forms of cheating revolve around modding the game locally so that certain textures can be seen through walls, so you always know where opponents are. So you aren't breaking any laws of physics, you are just able to make much better tactical decisions.

The obvious solution would be, just don't send data to the player's client about enemies that are behind walls. But this is a surprisingly hard thing to engineer in realtime games without breaking the player experience (see: https://technology.riotgames.com/news/demolishing-wallhacks-..., and then notice that even in the final video wallhacks are still possible, they're just more delayed).

In Minecraft one of the common ways to catch people using x-ray hacks or transparent texture packs is to run statistics on the blocks mined. If the ratio of stone-to-diamond gets significantly out of whack it's a sure sign someone is cheating.

In blackjack card counting is (probabilistically) caught by tracking player winnings. If someone is beating the odds a bit too much it's a fairly good indicator they are counting cards. Of course in this case getting it wrong isn't so bad from the casinos perspective either since then they'll just kick out a player that was costing them money anyhow.

When the enigma cypher got cracked they had to be very careful about when to act on information gained. If they started beating the odds too much the Germans would cotton on to enigma being broken.

My point being that cheating will almost by definition improve your odds. There are definitely ways to catch that sort of thing happening without installing rootkits. You just might need to hire a couple mathematicians to figure it out.
