  • It’s a special experience. Others have gone over the broad strokes, so I’ll instead describe my two favourite characters in the entirety of fiction.

    Sam Vimes is a pragmatic, down to earth everyman. In a world full of crime, racism, magic, and political shenanigans, he tries (and mostly succeeds) to be true to his beliefs and convictions. Convictions like female dwarves deserve to identify as female if they want to, no matter how much dwarven society despises any dwarf not sticking to male identities. That anyone and everyone deserves to be hired and promoted on merit, no matter the stigma around ghouls, zombies and werewolves. He cares about his people and his city, and really tries. He may not fully understand your culture or religion, but he will defend your right to it to the death.

    Rincewind is the opposite of the hero archetype. He’s the coward with a thousand backs. A failed wizard, because the immensely powerful spell living in his head scares off all the other spells, all he wants is to live a nice, calm, peaceful life. Against his will, he’s dragged from adventure to adventure and runs away from every exciting and mystical thing in the world. He’s seen everything, done everything, and never wanted to step out of the Unseen University.










  • So, first of all, thank you for the cogent attempt at responding. We may disagree, but I sincerely respect the effort you put into the comment.

    The specific part that I thought seemed like a pretty big claim was that human brains are “simply” more complex neural networks and that the outputs are based strictly on training data.

    Is it not well established that animals learn and use reward circuitry like the role of dopamine in neuromodulation?

    While true, this is way too reductive to be a one to one comparison with LLMs. Humans have genetic instinct and body-mind connection that isn’t cleanly mappable onto a neural network. For example, biologists are only just now scraping the surface of the link between the brain and the gut microbiome, which plays a much larger role on cognition than previously thought.

    Another example where the brain = neural network model breaks down is the fact that the two hemispheres are much more separated than previously thought. So much so that some neuroscientists are saying that each person has, in effect, 2 different brains with 2 different personalities that communicate via the corpus callosum.

    There’s many more examples I could bring up, but my core point is that the analogy of neural network = brain is just that, a simplistic analogy, on the same level as thinking about gravity only as “the force that pushes you downwards”.

    To say that we fully understand the brain, to the point where we can even make a model of a mosquito’s brain (220,000 neurons), I think is mistaken. I’m not saying we’ll never understand the brain enough to attempt such a thing, I’m just saying that drawing a casual equivalence between mammalian brains and neural networks is woefully inadequate.




  • I’m happy with the Oxford definition: “the ability to acquire and apply knowledge and skills”.

    LLMs don’t have knowledge as they don’t actually understand anything. They are algorithmic response generators that apply scores to tokens, and spit out the highest scoring token considering all previous tokens.

    If asked to answer 10*5, they can’t reason through the math. They can only recognize 10, * and 5 as tokens in the training data that is usually followed by the 50 token. Thus, 50 is the highest scoring token, and is the answer it will choose. Things get more interesting when you ask questions that aren’t in the training data. If it has nothing more direct to copy from, it will regurgitate a sequence of tokens that sounds as close as possible to something in the training data: thus a hallucination.






  • So on the gaming front, pretty much any mainstream Linux distro would work for that. Proton is pretty damn stable and great on any distro that supports Steam. If you like Bazzite though, you do you.

    For pen testing, must-have skills are nmap, bash, sqlmap, wireshark and the burp suite. If you know how to use all those, you’ve got basic coverage of most common attack vectors (password cracking is also covered by bash, there’s 101 different password cracking algorithms in various CLI spps).

    I’m a lazy ass who doesn’t care much about customization, hopefully someone else can help you with that :))

    A quick Google shows that someone got sharex working on Linux: https://github.com/ShareX/ShareX/issues/6531

    Might take some effort and learning bash and WINE + winetricks to get that running, but hey, you’re gonna need to do that anyways for the pentest stuff :)
