If something apparently isn't available on LibGen or SciHub, am I out of luck? Is there anywhere else I can ask?

>with upper-end prices on amazon marketplace, there would be two or more vendors somehow increasing their prices on a daily basis to dizzying heights

That's a slightly different thing I think - most tech savvy sellers on Marketplace revise their prices multiple times per day, to snipe at their competitors and drive prices down, ie to be the cheapest by a couple of pennies - when you see prices rising to stupid heights, it's nearly always an algorithm going wrong in some way. As an example, I once knew of/detected a competing seller scraping the prices of the company I worked for, so I made the system detect and show them slightly higher prices to break their algorithm - that kind of thing goes on a lot.

Huh, mine too. If you write the multiplication symbol explicitly it'll say 9. Clearly scientific calculators have additional grouping rules on top of BODMAS that most computer tools don't. I think programmer types will definitely parse it as 9 but if you've primarily used hardware calculators then sure, I guess.

I won't disagree with you. HP stopped making really great calculators about twenty years ago when they moved all the manufacturing to China. On the plus side, they are much cheaper now.

I have an ageing HP20S which is really good, it works fine, but the power button is gone so I have to hold a load of buttons down to get it alive and have to wait for it to time-out to switch off, so it eats batteries more than it did originally. Sad times.

As I understand it Aspect's experiment doesn't completely rule out hidden variables it just means that if they exist they must be non-local.

What's so bad about that? Maybe the hidden variables simply exist outside of spacetime. That's a lot more reasonable than observation "creating reality" or bazillions of parallel universes.

Based on half remembered popular science I read when I was 13, I think it's more that any time an outcome is undetermined, when the result is observed, all outcomes happen in different universes, and this includes our thought processes and decision making.

That's not how infinity works. There are infinite numbers between the integrals 3 and 4, but none of them are 5.

With infinite probability you're assuming that you can reduce the problem to something akin to "if you play the lottery infinite times, you'll win the lottery infinite times". However, without a guaranteed source of entropy we can't assume that infinite universes would be in any way different to our own.

In my early 20s I had to go on a course of antibiotics which seemed to coincide with IBS starting up. I've held the suspicion that the two might've been related in the sense that the antibiotics will have effected my gut biome. I got fluffy as well but that's more to do with being a greedy bastard.

Anyway, last week I had to start on a course of antibiotics again but this time the pharmacist managed to up-sell me some gut-bacteria pills to take with it. Do you think it was a silly purchase or do these things actually work? The science part of this thread is I will be able to tell you soon if they've worked.

Not the OP, but I have - the whole thing is fascinating to me. I think it might actually validate some of the ideas/hypothesis around the gut biome - not saying "probiotics" are anything other than snake oil, but there is clearly something in the science we have yet to discover. Also, some of the work that people are doing behind gut biome and depression/mood - very interesting. But still a bit gross. Maybe there is something in that ice docking business?

As I'm sure you've all been gripped with suspense regarding my bowel movements: I can report that things are running much better. That's nothing scientific but I've even been shagging my guts out this week by going back on huel with coffee with the side effects being much milder (just a bit of bloat).

I'd recommend it. Maybe I'll get some different types so there's an ongoing cycle of different bacteria and I'll see how it changes things.

4629 GS guide to fighting climate change
The problem of climate change can sometimes seem insurmountable. However, there are little things you can do which can have a big impact.

Easy mode
-If you have a workplace pension, consider changing your fund preferences into one that looks after the environment
-Use public transport over the car
-Have meat free Mondays, become a 'flexitarian'
-Switch to a renewable energy tariff. This way your energy only comes from renewable sources. There's one I've found called Octopus Energy which is quite competitive price wise.
-Grow your own veg/fruit
-Reduce, refuse, reuse and recycle (on waste/plastic)

Medium
-Cycle or walk to work
-Become vegetarian
-Insulate your house or upgrade to an environmentally friendly boiler
-Limit air travel to only a few holidays per year and don't fly long haul

It's piss-easy to make - one cup of rolled oats, three cups of water, blend for 30-40 seconds and strain through a coffee filter or a fine sieve. Add salt and/or sugar to taste. If it has a claggy porridge texture, you've blended for too long.

I like Partly the best, and it seems most people do because it keeps selling out at the local Sainsbury's. There's a 'full fat' version that's the best imo. I suppose the benefit to buying it is they add minerals to make it an actual milk substitute, if your diet would otherwise be lacking (as it probably would be if you're vegan).

It acts as a water reservoir, so it'll help prevent the soil from getting either too wet or too dry. It's not necessary, but it'll improve your chances of success.

f = f(x, y)

df = f(x + dx, y + dy) - f(x, y)
= f(x + dx, y + dy) - f(x, y + dy) + f(x, y + dy)- f(x, y)
= f_x.dx + f_y.dy

because evaluating the partial derivative at y+dy instead of y doesn't make any difference, right?

Not really sure where else to post this, so going to have a punt there.

My mother wants to do one of those home DNA testing kits (23 and me etc). Beyond pricing (which I don't really give too much of a shit about) are there any real distinctions between the companies offering these services?

While my 70-odd year old mum doesn't really need to worry about getting profiled for online advertising or whatever I'd prefer to not hand her genetic material over to a company who openly sells it for profit, and I'd rather a company that does honest comparisons rather than "we'll just choose a random genetic group for that 3% we can't recognise from our database" type shenanigans.

Thanks in advance for any advice lads.

Legally yes, but there's no guarantee that they won't just illegally transfer the data offshore. The GDPR gives you strong protections against companies with something to lose, but a lot of the DNA testing startups are offering tests at below cost; their business model wholly depends on being able to sell user data.
