I'm not sure if we'll see >10G over twisted pair/CAT but I'm sure we'll definitely see 5G and 10G baseT become far cheaper with 2.5G the baseline (e.g standard on cheap things like raspberry pi).

Base level Mac studio is already 10G as standard and it's only $100 extra on a mac mini.

Long time until 10G per device isn't enough at home.

I love this and agree with it almost in entirety. One thing that would be good to retain is 'regions' e.g 3 DCs under 10KM apart linked with free/very low cost internal network. It is cheap to build in colo these days with the advent of campus XCs and ever lowering cost of DF, optics and 400G/800G switches.

This is cool! In my experience the absolute most important factor for performance is that we are able to hold the FIB in CPU Cache, and my reading of this is that at >250K prefixes patrica may use less space? Did you find this?

E.g with a CPU with say 256MB L3 cache lookups are many many times more performant because you don't need to check ram on many/any lookups. Hot top levels in L2 > hot path in local CCD L3 > rest somewhere in socket L3 > DRAM misses (ideally almost 0)

London is about 3X bigger than Amsterdam in terms of capacity. If you look at the core western europe market (so called FLAP-D) which I am rather familiar with London holds 35% of that market and Amsterdam about 12%. I'm not at all sold that the old rule of thumb that this market is about 25% of global capacity has been true since about 2023 because of the AI buildout in NA/ME.

Pretty much the only way I've seen a /48 split in practice is to get 256 /56 (one per site) then 256 /64 (one per VLAN).

/52 and /60 are quite common as well, predictably what with falling on a "letter boundary" and all

Interesting. I've only seen /60 when they're trying to split up a /56, and IMO it's a little unclean.

I am surprised a serious facility would be happy having 100 old LiPo batteries in a rack. That is a (nasty) fire waiting to happen IMO. These are old batteries that may even have minor physical damage from being dropped and will be in maybe a ~25-30c environment.

Laptop batteries are lithium ion not lithium polymer.

Sometimes, but usually polymer these days. e.g the most popular laptop is probably a macbook https://www.apple.com/uk/macbook-pro/specs/ https://www.apple.com/uk/macbook-air/specs/

Raspberry Pi Zero 2 W (512MB) and Pi3B (1G) are both still super cheap if you can cope with that much RAM.

I agree, OTOH there are many very cool things that we can build if we're able to assume a user can spare 2GB of RAM that we'd otherwise have to avoid entirely like 3D scenes with Three.js, in-browser video/photo editing. Should be making sure that extra memory is enabling genuinely richer functionality, not just compensating for developer laziness (fewer excuses now than ever for that).

Flash has supply (and price) problems too.

One thing that's not super obvious, but is happening - 'AI' is increasing demand for 'normal' (e.g cpu) compute. People are building more apps because the cost of software has reduced, these need deploying somewhere. More commits == more CI runs, then there's then the 'agent' usage, things like openclaw instances etc. Just because they are expanding, it might not mean they're betting the house on more GPUs (though likely a part of it)
