Impressive coverage, but how do you verify that the reverse engineering matches what the hardware expects? Do you find people who own those beds and get them to test stuff for you?

I particularly like per-pert PoE power monitoring on the RTL837x. I hooked that up to my netdata to get a full history of how much each device in my rack is drawing. Don't need a fancy PDU or separate power bricks for each device -- everything is powered by the $60 switch.

(This is a home network and I'm not at all bothered about single points of failure or lack of redundancy/failover.)

Four-fibre cable was about US$ 1.5/m (here in Switzerland, I am sure cheaper elsewhere).

I picked ONTi JT-S508CL-8S as the main 10G fibre switch (direct from Ali, for about 100 bucks).

For wired Ethernet and PoE, I have a couple of KeepLink KP-9000-9XHPML-X switches (I paid about 60 buck for each, they seem to cost around $85 now). I find that they work well and use them for 10/100/1000/2500 GbE switching and to power various devices (other switches, U7-Pro-XGS AP, Zigbee dongle, home automation server, rack fans etc).

The main splice box was about 60 bucks, 24 pigtails included.

From memory, 10G SFP+ fibre modules were about ten bucks apieces. (DAC cables are cheaper, 10G copper transceivers are more expensive.)

Plus various paraphenalia (wall face plates, keystone modules, more pigtails etc), all of which was pretty cheap.

Note that I was able to borrow a fusion splicer from a friend. Otherwise they seem to start at around 500 bucks; buying one would have been the single biggest expense.

I also run a 25G path from one point in my flat to my ISP. The cabling is exactly the same but 25G switching equipment and optics are considerably more expensive and less available than 10G.

I can't tell if you're being sarcastic, but on my full desktop browser the side bar overlaps the main panel, putting text on top of other text.

P.S. Other than this, I do like the presentation.

I love the idea, but is there a risk that folks would drop off one by one and over time forget that the thing existed?

As someone who'd be at risk of forgetting, I'd find it nice to be periodically reminded about such a digest. Maybe get an abridged version once in a while or something like that.

It obviously confounds fragility with participation but, still, it must mean that people continue to use bikes -- I'm guessing increasingly e-bikes -- well into their old age.

(42% is 118/281 in the report.)

One thing worth pointing out: Moscow was very different from the rest of the country. It had better housing and infrastructure, the shops were stocked far better than elsewhere in the country, it had more grandiose architecture and richer cultural life and so on.

In many is ways it was the country's showcase city.

As of Feb, Amazon held $45.8 billion of convertible notes and $14.8 billion of nonvoting preferred stock in Anthropic.
