> provide better long-term compatibility than many native games

This is one of the big, but less obvious, benefits to Wine/Proton. Games with native Linux builds run into all kinds of distro-specific issues that you don't really get on Windows. It's an issue for new games and an even worse issue for older games that aren't being updated anymore. Just look at Steam on macOS to see how big of an issue this is - so many games are not compatible on the latest Macs because they were built for x86 (32-bit).

this only holds through if the data to be accessed is less valuable than the computational cost. in this case, that is false and spending a few dollars to scrape data is more than worth.

reducing the problem to a cost issue is bound to be short sighted.

This is not about preventing crawling entirely, it's about finding a way to prevent crawlers from repeatedly everything way too frequently just because crawling is just very cheap. Of course it will always be worth it to crawl the Linux Kernel mailing list, but maybe with a high enough cost per crawl the crawlers will learn to be fine with only crawling it once per hour for example

Less "social" would be a feature for me. I just want one that can plan routes, track journeys, and give me directions. I don't want to be worried that I'm accidentally sharing what I'm doing/where I am with the world.

r0uv3n · 7 months ago

Eh, the social features of Komoot were never intrusive to me, and among social features of most apps they were some of the most well designed. Local community, very much focused on actually sharing tracks and trying out other people's routes (and maybe commenting with your experience afterwards).

There was a guy in his 60s regularly doing very nice circular hiking routes of 40 to 60 km in our nearby forests, and apart from that just being kind of awesome and impressive to see when you look at local routes, actually walking his routes was often a very nice experience with diverse landscapes often along nice small, less used paths. It was great seeing nice weather in the morning, and then oftentimes without any pre-planning just walk or bike to the forest and just start along one of this guy's routes within a few minutes, all in an incredibly hassle free manner and with a result which pretty much always beat out just following the official hiking trails shown on signs etc. I don't know if there's another app right now where you can so easily profit from the experience and knowledge of your local community.

One only need a web server to share gpx files really.

Planning routes can be easily done offline with desktop apps. Don't even start with mobile use, I have never seen a web based tool where you could plan a route by tapping on a smartphone screen without pulling your hair out of desperation.

r0uv3n · 7 months ago

Well, Komoot worked quite well for exactly that use case. I have also only very rarely found tools even in the desktop space that were quite as mature as Komoot for that use case.

Also the question remains, what do you navigate the planned routes / gpx traces? What happens if you notice you want to improvise and replan to hit some target on the way you saw in the distance while on the trail? This was (and currently still is) absolutely trivial and intuitive to do on Komoot. The best alternative I can think of is maybe brouter+ osmand, but that's really quite clunky in comparison with Komoot (similar to the experience you probably mean when talking about pulling your hair out)

> Energy and momentum are always conserved in EVERY physical process.

Veritasium recently claimed otherwise https://www.youtube.com/watch?v=lcjdwSY2AzM

r0uv3n · 8 months ago

That is about something entirely different. It more or less just says that energy might be lost if you have a flux towards infinity. It does not in any way claim e.g. that the divergence of the stress energy tensor is non-zero (which would be how I think most people would interpret energy/momentum conservation).

> Why wouldn't it be?

Because the whole concept of "shape" assumes properties of space that might not apply inside an event horizon?

r0uv3n · 8 months ago

Eh, space inside or outside the horizon is only different in so far as to whether it can reach our timelike infinity. Locally you cannot even tell where any horizon might be (just look at a small patch of a Penrose diagram near a horizon), they are very much something related to global properties of the spacetime. In particular it's not problematic to talk about some extended volume in spacetime occupied by mass, as long as the divergence of the stress energy tensor is 0.

The point where our notions of geometry would break down would be near the singularity, not near the horizon, and we don't even know if a volume enclosed by a horizon (i.e. anything you might call a black hole) necessarily has a singularity inside, it's just that our simple mathematical models all assume one.

Reading the title and knowing exactly what this is about kind of makes me feel old to be honest.

r0uv3n · 8 months ago

I think this is enough of a classic to be widely known even among younger people. I'm 23 (doing math msc) and I think all the CS people that I know would instantly recognize the 500 miles title.

Though I do somewhat envy the possibility of having read the article close to publication and feel in some sense part of the history when it crops up again like this.

2 for example is not in the sequence. Remember that you need the first differences to this sequence to obtain all natural numbers

vitorgrs · 10 months ago

I really like KDE in general, and how full featured it is, but their design just feels dated compared to all modern OSes and other DMs on Linux...

The only reason why I'm a gnome user, it's because of that.

And yes, I know I can just customize, but everytime I try, it just make KDE more sluggish for some reason, and doesn't really feels natural.

r0uv3n · 10 months ago

Have you tried Plasma 6 yet? To me it feels way more modern than Gnome.

> Lorentz invariance is also violated in QFT assuming non-zero temperature.

r0uv3n · a year ago

If you couple your system to a heat path that is at rest wrt a specific Lorentz frame, you of course lose Lorentz incariance. On the other hand the lagrangian of the standard model itself is to my knowledge fully Lorentz invariant.
