  • Depends on what your goal is. Strictly speaking cc by sa is more permissive than putting no copyright notice at all, since copyright is automatic, and the cc licenses grant various permissions not contained in standard copyright. It’s just a fancy legalistic way of saying “please credit me if you use this, continue to share in a similar fashion, but not for any commercial purpose”.

    So if you want people to share your work, cc by sa makes sense.


  • As someone in the dev team for a “business app”, we probably know about most or all of them, but they’re just not important enough for anyone in management to prioritize them as part of a sprint. It’s also possible no one has given us reproducible steps to make them happen, so we just straight up don’t know what to fix. Usually the former though.










  • In addition to what atmur said, EVs don’t have the baseline inefficiencies an internal combustion engine requires just to keep itself running. ICEs waste a huge amount of energy just running, which gets lost as heat, vibration, and noise. EVs have the advantage of being able to run just as much as needed, so you don’t throw away huge amounts of energy at low speeds.

    The efficiency curve of an ICE vehicle generally peaks somewhere around 70-90km/h, due to a combination of wasted energy at low speeds and gearing ratios. EVs peak much lower, generally in the 35-55km/h range. This is due to not having the low speed overhead of an ICE, but still being subject to high speed inefficiencies like rolling resistance and drag.



  • I wasn’t speaking about PPPoE specifically when I made my post, all wired ethernet traffic only travels from sender to recipient without being visible to any other devices that’s not in the direct communication chain. This wasn’t always true. A network hub will send out incoming data to every single port, but hubs haven’t been in common use for decades. A network switch is aware of what is plugged in where, and will only send received data out whichever specific port the destination is connected to. If you have three PCs plugged into a network switch and PC1 needs to send a packet to PC2, PC3 has no way of even knowing it happened.

    That said, your final point is correct, and ARP spoofing defeats this. It had completely slipped my mind when I made the above post.
