  • 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.



  • I view it as sidelining cars to improve public transportation.

    • First thing is to eliminate and revise public zoning laws and removing parking minimums. This causes change the slowest but is the most important to start since it will lead to denser population centers, and parking garages can be closer to residence.
    • Second move I think is to eliminate extra lanes and trim road widths. This leads to driving being something that takes more focus and is slower. This also frees space for bike lanes and even dedicated bus lanes.
    • Slowly phase out free parking across the city. Start with spots directly next to crosswalks so that there is better visibility of pedestrians crossing. Then focus on bus routes to free a dedicated lane when possible. This discourages driving since there’s fewer chances you’ll be able to park close to the place you are going.
    • While this is occurring, you should be introducing public transit as it becomes feasible. More buses or trams, guarded bike lanes, etc.
    • MAINTAIN YOUR PUBLIC TRANSIT!! As trains and buses fall into disrepair the number of people willing to ride it will drop off. Also keep the bike lanes and sidewalks clear and smooth.

    That’s what I’ve got. It takes decades to break down this infrastructure for new stuff. You also need the to be having accessibility in mind whenever you are thinking about installing public amenities or removing infrastructure.







  • One thing I think should definitely be put out there more loudly is that Alexithymia(emotional blindness) is likely very common among dudes. I’m mostly going off personal experience, and how I’ve had issues identifying my emotions, and how I’ve heard some dudes I’ve talked to straight up just say they think they don’t feel things. I suspect potentially most dudes don’t understand how to detect emotions outside of very intense sadness, anger, etc. and I think that they need that communicated and a path they can maybe follow.

    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.
