  • Ok, I’ve done some double checking: The Bantu expansion is approximately what I thought it was. I believe the language group I was thinking about that survived the Bantu expansion was the Khoisan.

    My (very coarse) knowledge of this comes from a mixture of reading Jared Diamond (Guns, Germs and Steel) and from following it up with some Wikipedia. In short: The genetic makeup in a lot of the world is relatively dominated by the groups that were the first to adopt agriculture in their respective regions. Before the Bantu expansion, phenotypes south of Sahara were more varied, just like the phenotypes in the Americas were more varied before the corresponding “European expansion”, or the equivalent expansion that happened in South-East Asia (I don’t remember which society stood behind that one).

    According to Diamond, we can trace a lot of (most?) surviving human phenotypes and languages back to relatively few societies, which after adopting agriculture, more or less wiped out / displaced neighbouring cultures due to increased resistance to a lot of infectious diseases and massively increased food production / need for land. This mostly happened less than 10 000 years ago, i.e. far too recently for natural selection to have a major impact on things like skin colour, hair type, height, facial features, etc. afterwards.

    So: While major trends in phenotypes are of course a result of natural selection / evolutionary pressure in specific regions (resistance to skin cancer / sunburn vs. vitamin D production, or cooling down more efficiently with a wider nose vs. retaining heat with a slimmer one, or having an eye-shape that lets in more light vs. provides more shade), a lot of what we see today is simply a result of what phenotype the first group a given region that adopted agriculture had. This means that looking at the dominant phenotype in a region today will not necessarily give a good impression of what phenotype that is “optimally designed” to survive in the conditions of that region.


  • I seem to remember that the majority traits south of Sahara (black/very dark skin, and curly hair) can be traced back to something called the “great Bantu expansion”, which was essentially the result of a group of people with these traits developing agriculture and wiping out most other peoples south of Sahara, much like the Europeans did to the Americas.

    Some cultures south of Sahara did survive, which can be seen both genetically, and in some languages that are completely from other languages in the area (I believe the family of languages with “clicking” sounds is an example).

    I’m on my phone now, but I’ll have a double check and come back.



  • Sorry, but I honestly don’t get it. I I were to point out the crown jewel of open source, it’s gcc. gcc is the backbone and survival condition for so much modern industry that it’s not even remotely funny.

    Take away gcc, and the world will likely burn for a substantial amount of time until people start making in-house or proprietary alternatives.



  • I didn’t say that. I’m pointing out that we spent shitloads of money that could have gone to out own schools and healthcare, and a dozens of young soldiers lives (I’m not American), and we were clearly told by both the local population and a bunch of other countries to fuck off.

    So yes. I’ll say it. Fuck em. We don’t owe them shit. We came down there, suppressed the Taliban, built s schools and hospitals, and secured elections, and when we left, the Afghan army, which we had trained and supplied, folded immediately.

    We can’t be held responsible for them not revolting against a suppressive regime. We gave them all the tools to keep the taliban out, but they chose to fold. That’s on them.

    It’s tragic, but that’s how it is. If they’re not willing to fight for their own rights, they won’t get to enjoy them.





  • I’ve been wondering for a while: What is preventing a bunch of not-drowning-in-corruption countries from just not recognising FIFA any more, saying they’re sick of the blatant corruption, and starting their own international association? I would think you could get a lot of the major football nations to support something like that, because it looks like it’s mostly Quatar, Saudi-Arabia and the likes which benefit from the current system…



  • I mean, it’s no secret that a bunch of countries are running massive disinformation campaigns in order to divide the populations of western countries. Attempting to destabilise another country by propping up certain political factions is a tactic that has been employed across the world for at least the past century (see: Lenin, and how he got in power).

    Of course, we are responsible for ensuring that we do not become fascist states, but acting like theres no outside influence propping up the fascists is naive at best.




  • This is so facinating! I remember hearing about this around 2016 when they did excavations, but didn’t know they found the guy already in the 1930s. It’s just awesome that the story of how this person died has survived a thousand years through the sagas.

    I do think it’s a bit weird that the article focuses on whether he had some disease though- obviously throwing a dead person in the well is going to make the water undrinkable, regardless of whether said person was sick when they died…


  • I am/was in the same boat as you: For a long time, I just didn’t care that I was giving away a bunch of information in return for convenience, and didn’t get why people cared so much.

    I don’t really know what triggered it, but at some point I became painfully aware that the only goal these companies have is to squeeze every possible penny out of selling me. I started noticing that the stuff they ask you to confirm is 95% stuff they want because they can sell it, or use it to get you hooked to their service, and 5% (at best) stuff they need to make the service good for you.

    This triggered a change in my perspective: Now it pretty much makes me sick to my stomach to think about all the companies that are drooling over me, trying to make a buck by getting me to click something I’m not actually interested in, or don’t actually need.

    These people have a vested interest in manipulating me, and by giving them my data, I’m giving them the tools to do it. I don’t want to be manipulated or sold as a product: That’s what made me start caring about protecting my data.


  • What you’re thinking about is the relation between energy, temperature, and heat capacity. When you add energy to a system (e.g. heat) the amount of energy you need to heat it up a certain amount is described by its heat capacity. If your molecules can “wiggle” (i.e. they’re multi-atomic) a portion of the energy you’re adding will go to increasing the “wiggling” rather than the mean speed of the molecules.

    What we perceive as temperature is related to the mean speed of the molecules, so because molecules that can “wiggle” more will require more heat to see the same increase in mean speed as non-wiggling molecules (because some of the heat is going to increasing the wiggling) they have higher heat capacity.

    It should also be mentioned that even the concept of temperature is really a statistical concept, so it doesn’t really make much sense to talk about the temperature of a single isolated molecule, or even a pair of them. Temperature as a concept starts to be fruitful to talk about in the thermodynamic limit which classically means “a whole shitload of molecules”, but (relatively) recent research suggests “a whole shitload” can be as little as 10-30 molecules. Once you go below the thermodynamic limit, we’re not really talking about the temperature of a system, but it’s energy, which is still well defined (although definitions may vary depending on context). Depending on who you ask, it can make sense to define a temperature also for single-particle systems, but at that point we’re talking about applying thermodynamic definitions that work (and are correct in the macroscopic limit) and no longer about what we classically perceive as temperature.


  • This will sound dumb, but I’m saying it sincerely.

    I’ve had similar issues (without getting into details), but what worked for me was getting outside a couple times a week. By that I mean bringing a tent or hammock + tarp and sleeping outside a couple nights a week on workdays.

    To be specific: I sleep outside Monday-Tuesday and Wednesday-Thursday. On those days I also make my dinner at my campsite. What I’ve found is that my brain goes into a much more “primal” state of “monke outside in cold, monke get shit done”, and that it propagates into my day and week.

    The barrier to this is of course actually going outside, but I’ve been able to get to a place where I have a “deal with myself” about those two nights a week. I always have my pack ready, so it’s just about grabbing it and heading out- I think that’s key.

    I’m not saying this is a solution for everyone, but it’s done wonders for me. As of now, I get restless and feel bad if I’m in a situation where I can’t get outside at least once a week. It brings me a peace of mind and will to get stuff done that nothing else can.
