  • You haven’t mentioned what sort of access link or speed you have, that seems very relevant here.

    For my 1Gbit/s fiber connection the Edgerouter 6P has been pretty good. It has an SFP port and can route 1 Gbit/s of traffic without issue and my dual-stack setup works well too.

    The only significant downside is that its switching is slow, it has no hw support. So I put my NAS on a separate subnet instead so that the traffic to it can be routed instead.


  • When I first played DOOM I was a bit afraid of the monster sounds. I would usually ask my little sister if she could color her things in my room so I wouldn’t be alone while playing. I was way too bad to ever finish the game back then. I used to ask my father to make me “untötbar” (unkillable) because the word “unverwundbar” (invulnerable) was too difficult for me.

    But I really like the reboot and DOOM Eternal especially.




  • “in the lab” is always a dangerous one. If the Tokyo U people only just demonstrated that hard carbon electrode, then who knows if it can be produced at an industrial scale and if that can be done economically. Even if it can, maybe there is still enough time until production picks up that one more technological refresh on the LiFePO4 production is justified in the mean time.

    Besides, there is some inherent inertia, in research, in the markets, in politics. Even if a clear technological winner emerged suddenly some researchers would still have a year or two to finish their grant and publish their findings, some production lines would produce until their eventual superior replacements come online and the stocks would be sold off, and some subsidies would still be payed out until a new law could redirect the funds to only support the acceleration of the new best thing.















  • USB Type-C is not all over the place, it’s a pretty normal connector standard, that was updated a few times.

    What may be confusing to is that there are also two other relevant standards:

    • USB Power Delivery 2.0 and its updates
    • USB 3.0 and its updates

    Both of these standards require the USB Type-C connector for some of their features. Sometimes in a specific revision, for example at least USB Type-C Rev 2.1 is required for the Extendend Power Range introduced in USB Power Delivery 3.1 for charging at more than 100W.

    Furthermore USB 3.1 has absorbed USB 3.0 and USB 3.2 has absorbed USB 3.1. Each time they renamed the old connection speeds. For example a USB 3.2 Gen 1×1 connection used to be called a USB 3.1 Gen 1 connection and before USB 3.1 came out it was called a USB 3.0 connection.

    Finally USB Type-C has so called alternate modes, where the lanes for SuperSpeed USB can instead be assigned to carry other protocols, like DisplayPort.

    Since very few features are actually required to be supported, and marketing managers are apparently allergic to precision, it’s hard to find out what feature is supported on which interface for any given device.
