  • I understand some instruction expansions today are used to good effect in x86, but that there are also a sizeable number of instructions that are rarely utilized by compilers and are mostly only continuing to exist for backwards compatibility. That does not really make me think “more instructions are usually better”. It makes me think “CISC ISAs are usually bloated with unused instructions”.

    My whole understanding is that while more specific instruction options do provide benefits, the use-cases of these instructions make up a small amount of code and often sacrifice single-cycle completion. The most commonly cited benefit for RISC is that RISC can complete more work (measured in ‘clockcycles per program’ over ‘clockrate’) in a shorter cyclecount, and it’s often argued that it does so at a lower energy cost.

    I imagine that RISC-V will introduce other standards in the future (hopefully after it’s finalized the ones already waiting), hopefully with thoroughly thought out instructions that will actually find regular use.

    I do see RISC-V proponents running simulated benchmarks showing RISC-V is more effective. I have not seen anything similar from x86 proponents, who usually either make general arguments, or worse , just point at the modern x86 chips that have decades of research, funding, and design behind them.

    Overall, I see alot of doubt that ISAs even matter to performance in any significant fashion, and I believe it for performance at the GHz/s level of speed.



  • You already have an entire vocabulary for solar time (sunrise, morning, noon, evening, sunset, night, midnight). This being all of a sudden assigned to a different time on a clock does not change things in any dramatic fashion. It would also be a consistent change for your current location, guarantee it only takes you less than a work week to acclimate.

    All the things you’ve described I’ve literally been doing for 6 months now. It is not a noticable difference and does not impact me.

    Also, a book that says “it was 5 o’clock” is objectively more boring than one that describes the shadows of twilight blanketing the scene in a checkering of shadow. Also TV shows show outside, where solar time is visibly apparent. The specific time is not nearly as relevant.

    Also, you already look up time zones when scheduling international meetings, and those aren’t going to tell you about siestas or other local practices which might affect scheduling. Maybe just actually ask the person what times will work when trying to schedule, and now since you’re both using UTC, you both can figure it out together without looking up timezones.

    I watched though about half of it, before concluding that this video is only going to be a summary video that won’t answer my questions fully.

    Digital ID and Digital signature are absolutely necessary, though depending on how those two are implemented I could still see fraud and vote manipulation being feasible. I was hoping someone with more knowledge about how Estonia is doing its security and verification systems to ensure records aren’t being modified maliciously.
