  • Just because a CISC will run multiple instructions in a single clock cycle, it doesn’t automatically make it faster. Complex instructions means complex decode logic, that makes the execution slower, even at the same clock cycle. A modern intel CPU has something like 20+ stages of pipelining, while ARM has 3-5 stages, that makes the execution more energy efficient and more powerful. Also superscalar RISC architectures exist, so RISC can also execute more instructions at a time, and in less time.

    Lastly, modern x86_64 look like CISC, but are actually RISC under the hood, the single instruction is just a pseudo-instruction divided in multiple simpler instructions. I don’t believe thay makes it much more efficient.




  • Also certificate does not ensure the website is safe, only that you are really talking with the server the URL points to, and not a man-in-the-middle trying to hijack your information (like passwords or payment details).

    Nothing stops a malicious site to have a valid https certificate. Sure, more spam-friendly Certification Authorities like Let’s Encrypt might revoke spammy certificate, but that’s not nevesserily always true.




  • To a certain extent yes, but at least on most social you at least follow single creators you enjoy, and you are usually presented with a lost of content they made so you choose. With tik tok you are served a random video and the algorithm chooses the next one, I don’t even know if when finished to see a video you can get a list of reccommended of you are served one only. It’s just a differenr structure.





  • Social media. Started strong in the mid 2000’s, peaked in features and quality and social usefulness in the early 2010’s and around 2014 they started removing features and enshittify because they got their core userbase and, once locked in, they could milk them.

    Remeber when facebook was about “connecting with old friends” and you could search by city, age range and a whole lot of filters? Or when YouTube was “broadcast yourself” and could fully customize your channel page? Then they reduced it to a stupid banner that got smaller and smaller.

    Bonus: everything that relies on infinite growth to keep cost down. I was skeptical of streaming services and guess what, they suck because they operated at loss for years, because “more future customers pay for the present ones”


  • IQ does not measure intelligence, it measures different fields of intellect, mostly about logic, language comprehension and memory. It doesn’t measure intelligence per se, but if you have a low score <70, you can be sure your life is going to be impacted negatively in some way, either because you don’t understand other people, you don’t understand the world or you cannot chain together complex logical chains.



  • Global warming is not about producing more energy, it’s about burning fossil fuels instead of clean energy (renewables, nuclear…) and about wasting energy.

    But it’s not as easy, technically everytime you use your car you become “part of the problem”, or everytime you buy some useless single-use crap from temu, but I think it’s unfair to blame yourself for it. The system allows and encourages wastes and “problematic behaviour” because it’s either more profitable (see bigger cars in the US) or changing is more difficult and politically inconvenient.
