  • Taxonomically speaking, birds are dinosaurs.

    There isn’t a place to put a line between them - all the things that make birds “birds” also apply to dinosaurs.

    A super fun fact is that of the two main types of dinosaur, Saurischia (“lizard-hipped”) and Ornithischia (“bird-hipped”), birds actually evolved from the lizard-hipped group.










  • It’s a ridiculous take that the political minutiae of the US is largely meaningless to people outside the US?

    Look, it’s enough for me to know that the USA has made a thinly veiled threat about forcibly taking over Greenland. This is of immediate concern to me.

    I don’t need to know the details of what the American version of Göring said in defence of the American version of the Gestapo this week.

    We have our own domestic nonsense that I’m sure you don’t get inundated with - why would it be so ridiculous for us not to want to get bombarded with yours?

    He was. He just didn’t get the mechanism behind it right.

    A crude way of explaining Lamarckian evolution would be to look at giraffes. Lamarckism suggests that because an animal that spends much of its life stretching its neck to reach food, it ends up with a slightly longer neck. This trait is then passed down to children, who might spend much of their lives stretching their necks, making them slightly longer. And so on.

    He correctly identified that speciation occurs over many many generations, as a result of tiny incremental changes.

    What Darwin did was to recognise the actual mechanism behind speciation - Natural Selection. Darwin was aware of and built on Lamarck’s work.

    Weirdly, within the last thirty years, we’ve realised that the truth is not so clear cut. Epigenetic changes do occur as a result of the environment and are hereditary. While genes are still the main drivers of evolution, these epigenetic changes affect gene expression.





  • I’m going to go against the grain here and say “kinda”.

    But porn isn’t the driver, it was a facet of the actual reason - accessibility and cost.

    Betamax was, by any metric, the superior system.

    VHS, however, was cheaper to produce, and cheaper to buy the recording equipment.

    JVC had an open licencing strategy to encourage manufacturers to produce VHS-compatible equipment. Sony had a closed licencing strategy to maximise revenue.

    So in this new world, where small movie studios could now record directly to magnetic tape and small companies could duplicate and distribute copies for very little cost, which format would you pick? The cheapest one.

    The ready availability of porn was a factor for VHS’s success, but so was the ready availability of cheaply made horror films, martial arts films and other niche genres (niche by 1970s/1980s standards).



  • I feel lucky that I was born at a time when computers were knowable. I grew up in the 80s, and cut my teeth on a ZX Spectrum. Very little was hidden - even loading software into memory was something you experienced, listening to the beeps and warbles and watching the flashing colours for ten minutes or more. Guide books showed labelled photos and diagrams of the actual hardware inside, giving real tangible meaning to the commands you typed in.

    I think there’s a massive amount of disconnect now between the users and the actual hardware, and getting up to speed with how things work is so much more difficult.

    Also, I’m lucky that I was born into a family that was just able to afford a microcomputer. My dad had a stable enough job that he was able to get a loan from the bank to buy one.

    Not sure my life would have turned out the way it did without this starting point.



  • Ok, I think I’ve worked out what the issue is here.

    First of all, let’s go back to where Owen Jones starts off.

    The term chav refers to a specific subset of young people who spend a disproportionate amount of their money on fashionable clothes and hang around being a nuisance to other people.

    He also argues that the term is used by right-wing media outlets as a broader generalisation of working-class people as a whole, to further push their arguments.

    These two things can be true at the same time.

    But I’d definitely agree it’s not a slur. It’s just lazy journalism presenting a caricature of the working-class because it’s easier for their deranged arguments.

    The majority of people are born into working class families, but only a few become chavs.

    It’s a sad reflection on the country that the right-wing media is able to get away with presenting absolute rubbish with abandon, and it’s unfortunate that a lot of people consume this media without realising that they’re being told lies and half-truths.

    But that’s what the problem is. It’s not that the term itself is bad, it’s that bad people use the image it conjures to caricature the working class in general.


  • “Chav” doesn’t mean “working class” in the same way that “penguin” doesn’t mean “bird”.

    Heck, some of the chavs I know wouldn’t know work if it hit them.

    Chavs are a tiny subset of working class people, in the same way that penguins are a tiny subset of birds.

    I live in a northern mill town. Most of my very large extended family are working class (it’d probably be a bit disingenuous for me to claim that I still am, though). They would look at you like you were an idiot if you tried to convince them that chav means them.

    Chavs are the kids who hang around with expensive trainers and caps, who have absolutely no qualms about being a nuisance to other people.

    They represent a tiny proportion of the working class, and any criticism of them is specifically targeted at them.
