A lot of old hard rock and metal with power chords is easy to play a simplified version of. I think Metallica - ‘For whom the bell tolls’ and ‘Enter Sandman’ were probably the first things I learnt. You can learn enough to have fun playing a riff like that even if you struggle to get your hand into position to do proper 6-string chords.

I came across effect/affect swapping in university level textbook the other day, couldn’t believe it.

Lol at UK being more liberal than Ireland! Yes in terms of their abortion laws they were very behind until recently, but in every other way I can think of Ireland has been way more progressive. UK politics meanwhile (driven by middle England Sun readers) busy trying to brexit ourselves back to the spirit of the blitz or something. Can’t wait to get my blue passport, God save the king!

Power engineer? How is your job overall? Challenging in a good way and satisfying? Or stressy and boring? I’m studying right now, going on my first internship this summer with a network operator, can’t really imagine what to expect…

Can I ask your advice about some home locksmithing? I have a problem involving a password protected zip file from ten years ago, and a vault from an old Android password manager like keepassX or something. I have tried learning how to use johntheripper, but I want able to narrow down any of the parameters, so it was just doing the broadest brute force approach possible, which didn’t seem likely to work within my lifetime…

Thank you for sharing this! :-)

I’ve never seen it myself, but my wife spent most of her childhood/teenage years in Shetland, and apparently up there, back then, Smirnoff ice was the drink of choice for hard working middle aged men. We’re talking about a bunch of islands where the main employment is offshore fishing and the oil & gas industry, and where they’re very proud of their Viking heritage. (Image search Jarl squad to see what I mean, those guys who are picked for the squad will grow their beards all year to look the part)

It’s my favourite format. I think the original was ‘stop doing math’

Your second sentence does not follow logically from your first though. A randomly selected male might be half as likely as a randomly selected woman to be a victim of domestic violence, but what a man in the far smaller set of people who have googled that particular phrase? I would venture to say the ratio might be a lot closer

Not cool, mate. Too far. disappointed face.

I guess I was imagining it with the walls torn out as well, but you’re right the op (of this comment chain) said top and bottom broken. If the walls are somehow firmly fixed forever no matter how much force they experience, and are not subject to thermal degradation, then we have a square pipe with 3m sides and infinite length. If the walls break down then it’s also infinite diameter.

In terms of modelling it there’s a FOSS option openfoam.org but I don’t know how to use it and don’t have time to mess about with it right now.

It’s a really interesting question, I would love it if someone who understands this kind of physics properly would chime in!

By my understanding of Reynolds number etc, the faster they go, the more turbulent the flow, so the rocks would be constantly hitting against each other sideways, and surely grind to dust in the constantly accelerating scenario.

But maybe the infinite (looped) nature of this ‘dimension’ means that this logic doesn’t apply. What would even be the ‘characteristic length’? Are we thinking about established flow at the centre of an infinitely wide pipe? Am I wrong to think of constantly accelerating rocks with air in between as a type of fluid flow?

I don’t think the drag force due to air would work the same in a system with such a high concentration of rocks. It’s not like one object falling through undisturbed fluid, which then has to get out of the way, in this case the air would gradually start to move along with the rocks.

This might be better modelled as turbulent flow of a mixed solid/air suspension. But there’s no ‘edges’ to the flow due to the looped dimension, so the viscous forces are pretty uniform… There would still be a terminal velocity, but much much higher than a rock falling through an atmosphere

Also I imagine the rocks would quickly grind themselves to very fine dust, once they pick up a bit of kinetic energy, so then it would behave more like a fluid with uniform density… Could it even end up as laminar flow?

Look into lacto fermentation (home made pickles like real sauerkraut).

Basically make sure your jar is as clean as possible; chop up a little bit of cabbage, carrots, cauliflower, broccoli (any or all, this is just an easy beginner list, the possibilities are endless); jam it down in the jar leaving a good gap at the top, and packing it in to leave as little air as possible; top up with clean, salty water so the veggies are covered (not crazy loads of salt, but the water should taste like between blood and sea water) (can also use a weight to keep the veg submerged if necessary, like a clean glass with water in); cover, leave at room temp a few weeks; enjoy a delicious and healthy food that humans have maybe been doing since prehistory. I was going to say how it works, but ran out of time, look it up!

It’s not just you, it’s much safer to read disturbing content than watch it on TV, it has something to do with how your mind forms memories. I think while reading your mind will on some level make up pictures to go with it, but only has access to the libraries of what you can already imagine. So if you have nightmares about it later or whatever it can still be challenging, but it’s hard to get as traumatised as you can by seeing images on TV/film or irl. My source for this is something my wife read while we were researching ways to help our little girl, who gets freaked out by certain things on TV very easily. It seems to hold true for her at least.

Mate, you’re so right, can’t believe some of the takes on this! If I want to cook something a bit more involved, I nearly always make a big pot and freeze portions. People are complaining about texture, but it’s easy enough to: make a base out of your protein, sauce, spices and seasoning, and the sturdier veggies (eg Bolognese, chilli, curry, random sauce for pasta, their texture won’t suffer noticeably); freeze; then reheat and serve with a freshly cooked relevant carb (pasta, rice, couscous), and some kind of fresh green like salad or steamed broccoli. Or not! If you’re short on time just have your defrosted meal with toast and it’s still 80% as nutritious as a fresh home cooked meal This is coming from someone who worked in kitchens, including moderately fancy ones, for years, so I know how to do the opposite approach too. But now I have two kids, cooking something effortful without planning for leftovers feels like too much of a time-luxury.

What do you think a homeschool diet is like? I’m imagining high in veggies, low meat, maybe organic… Maybe lots of beans.
