Heh. I just spent half a minute squinting the dark trees in the background, looking for the outline of a car. I didn't realise the picture was swapped.

There are at least a couple of distros that are based on Ubuntu. Mint is a popular example. I'd say that based on Ubuntu means it is also a Debian derivative.

Perhaps this is what Musk means when it says that empathy is bad.

If your goal is to maximise your own personal wealth, then empathy really is a hindrance. But I put to you that maximising money is not a goal worth devoting a lifetime to. And perhaps not scamming dumb people is a valuable way to act regardless.

(This is essentially what motivated the Quakers to push for set prices for goods rather than constant bartering. They believed that dump people should still be able to go to a shop and buy stuff without getting ripped off. I'd say that moral position has made the world a slightly better place.)

But that will never happen, because electromagnetic forces haven't learned the power of friendship and co-operation. Gravity always works together, but the other fickle fundamental forces just can't decide if they are pushing or pulling or whatever.

That's true, but there is far more energy to gain by fusing hydrogen compared to carbon. I'm not sure how it compares to uranium though. I suspect it might be similar. (I mean, obviously in practice you wouldn't / couldn't actually get the energy from fusing carbon - but we can still compare hypothetically. ... also, I'm sure we could get a clear answer by looking it up; but this is one of those things where thinking about it is probably more interesting than knowing the answer.)

I was thinking the same thing. It's unfair compare chemical energy to nuclear energy. Coal still kind of sucks, but the hydrogen in the others could definitely be used in fusion...

Blocking means that you don't have to devote your time and thoughts to that person. That's pretty valuable. And even if they decide they are going to attack you, not-responding is often a good strategy vs that kind of crap anyway - to avoid getting pulled into an endless bad-faith argument. (I'd still suggest not announcing that you've blocked them though. Just block and forget about it.)

Every tech can be safe and unsafe? I think you've oversimplified to the point of meaninglessness. Obviously some technologies are safer than others, and some are more useful than others, and some have overwhelming negative effects. Different tech can and should be discussed and considered on a case by case basis - not just some "every tech is good and bad" nonsense.

I'm not suggesting that we ignore the problems. I'm suggesting that we don't let trivial things, such as playing a computer game poorly, distract us from the problems. This post is not an example of behaviour that needs to be confronted.

Maybe; but either way it means he gets to have more air-time and head-space.

Being disliked for someone trivial, such as being bad at a computer game, doesn't really translate across to more important things. So that reputational damage is shallow and unimportant, but maintaining his position as being newsworthy is powerful and useful to Musk. So I agree with the other guy: better to not fuel these discussions about trivial junk. If you want to keep talking about Musk, then stick to stuff that matters.

I don't have an account there, so it's surprising to hear that it has pizza smeared all over it.

So intimate and close, you can still smell his presence.

I'm intending to buy some gloves to use for commuting on cold days. I'm looking for something wind-proof, fairly light, and hopefully a bit water resistant.

Here are three sets of gloves that I've been looking at:

  • Outdoor Research, commuter windstopper gloves
  • Arc'teryx, Venta gloves
  • Rab, Vapour-Rise gloves

I don't really know if any of those are good options. But they seem roughly what I'm looking for.

I'm wondering what gloves other people wear, and if you have any recommendations.

[edit] Although the primary purpose of the gloves is for commuting; I'd also like them to be my general "go to" gloves for whenever they are needed when visiting cold places.

 

tl;dr : Does Office 365 work well on Linux via winapps?


longer version:

At my work, I'm currently using my own (Windows) laptop. But its getting a bit long in the tooth, and my tolerance of Windows continues to drop... So I'm considering my options.

One option is to buy myself a new laptop and use Linux. The main barrier to this is that I use Office 365 stuff a lot for work. (Specifically: Word, Excel, and OneNote).

In my brief look around, my impression is that the only reliable way to get those products running on Linux is using winapps; which, as I understand it, basically runs the apps in a virtual machine but tries to make them look like they are running on the host OS.

(The alternative option is that my work will lend a Windows laptop to me indefinitely. But I generally like my stuff to be my own, and I don't like to create waste by accepting cheap and crap laptops with short life-spans.)

I'm writing here to ask if anyone has any experience using winapps. Does it work reliably? Is it easy to open and save files without any weirdness? Will I be able to use a stylus to write notes in OneNote?

 

This is a problem that I've given out many times as an example of an easy-to-understand but unsolved problem in maths. ... So it's slightly disappointing that I can't do that anymore! (But cool to see that progress is in fact possible in weird problems like this.)

 

I've just discovered this maths magazine (online, and in print). What I've seen so far looks good, and I'd never heard of it before - so I figured I'd share it here.

 

I've recently realised something about Pythagorean triads; a topic which very few people I know would be interested in hearing about... so I'm posting in here - a ghost town maths community. (But I'll also post on mastodon.). Anyway, the realisation is related to complex numbers.

If I have two complex numbers, I can multiply them like this: (x₁+y₁i)(x₂+y₂i), or like this r₁r₂cis(𝜃₁+𝜃₂). So then, if I represent a Pythagorean triad as a complex number, x+yi, with r as the hypotenuse, then multiplying two of these together is guaranteed to produce another triad. The rectangular method of multiplication guarantees integer real and imaginary components, and the polar method guarantees an integer hypotenuse. For example, (3+4i)(3+4i) = -7+24i. And 7²+24²=25².

So that's a bit interesting. But I have more. Since the polar angle in these triads is always an irrational multiple of 𝜋, repeatedly multiplying by the same triad will never return the angle to where it started. You'll just get new triads every time. But of course, if we are multiplying different triads together, its easy to come up with different ways of producing the same triad product. Following this line of thinking, we can view the Pythagorean triads as either 'prime' or 'composite'. Any triad can be written uniquely as a product of prime triads - just like with integers. (For this to fully work, we must allow 'flat' triads such as (1, 0, 1), (2, 0, 2), etc.)

How can we tell if a triad is prime? Well, I don't know - other than trying to brute-force the factorisation. If the hypotenuse is a prime number, then the triad is definitely prime. But if it isn't... I haven't thought much about that yet, but my current answer is to just check to see if a triad can be made with the factors of the hypotenuse.

Anyway, that's all I've got on that for now. No doubt there's some fully fleshed out details somewhere on a wikipedia page citing some well known facts from 2000 years ago or whatever. But discovering is more interesting that knowing. So I'm not going to check right now.

 

I'm looking for discussion and suggestions about the best way to play games from GOG on linux.

My current method is that I've got GOG Galaxy installed with bottles, and then I use GOG Galaxy to install and launch the Windows games. That's working alright so far. One downside is that won't install Iinux versions like that, so for games that have a native linux version I have to decide if I want to install it separately, or just run the windows version with the others. So that isn't perfect. Another minor thing I don't like is that since I'm installing games via GOG Galaxy via Bottles via Flatpak... I end up having very little idea of where stuff is being saved. It's difficult to find save game files for example; and if there is some junk installed or left over from something, there's very little chance that I'm going to notice and delete it. It just feels very opaque. (I guess that's mostly just about my personal lack of knowledge though.)

Anyway, I'm mostly just wondering how others are choosing to handle their games from GOG.
