In a home buildout, running fiber is surprisingly inexpensive and easy to do. There is one area to watch out for - In most US homes drywall is installed with screws that go into studs so if you have large bundles of wire or fiber be caref

There is no power over fiber.

"I never understand why anyone needs anything faster than 1G". i just upgraded my home network from 40g to 100g. g, not m. Anyone who does video knows the pain of 10g.

"(running fibre in the house isn't practical yet)" What does that mean? I assume you are saying most builders don't offer fiber? Running fiber in a house is entirely practical and easy to do. Cheap as well.

I ran fiber when I built my house a few years ago. I have MANY 12 fiber runs going to my IDF/MDFs, Server room, the gate, the dmarc, etc. I also ran SM fiber to every AP location. Out of 20 miles of pulls about 1 mile was fiber.

This is VERY true - especially for home use. You could have many db of loss and still have a perfectly functional 100g network.

I have a $1000 fusion splicer from Amazon, and it is fantastic. It is very straightforward to use, and for my home use it is perfect. If I did spicing as a job this wouldn't be the tool to use, but for occasional splices in my homela

"While I agree with the sentiments, there is a societal need for gatekeepers in some professions. The engineer title often comes with legal liabilities. It’s not necessarily just about talent. Of course it often becomes misused as well

That is a good estimate. You can see US non profit compensation online - https://datarepublican.com/nonprofit/assets/ Many of the presidents/vps make in that exact range (~$200 - $300k), although there are ot

It is ridiculous that your registrar was going to act on your domain without any kind of verification of jurisdiction. Can anyone just email a registrar and claim there is some injunction and have something removed?

"The uplink, in front of a directional VSAT antenna, this is very significant." This is reasonable, and I fully can understand that direct transmission at reasonable power going into a sensitive receiver can be problematic. In pra

I fully understand the risk of highly directional radiation - but that is why I was asking if there was some actual specific testing done. I believe the software in the Starlink (and the beamforming) is designed to only transmit when it kn

I'm an electrical engineer - I don't understand how what you said can be true at a wide and effective scale. Of course any device can interfere with something else - But what kind of evidence exists that starlink terminals, and in

The wikipedia page for the Tristan da Cuhna island is really interesting. It is amazing that a small population was able to survive there over such a large period of time with just occasional ship access (sometimes years apart). https:&#x

Interesting - I suppose it depends on how you count things. I have more than 100 smart light switches in my house, so if you add in smart plugs, sensors, cameras, etc I certainly have more than 300 'smart devices'. That has no

Ha! It is a funny thing.. one time I was trying to remember something specific about a calibration table in a Subaru ECU and I googled it and found a great answer.. and sure enough it was something I posted years before. Ah the beauty of

"That's not everyone of course, but that level of CTO with his hand in the bits just seems constantly dangerous." The biggest danger of a CTO being too deeply involved at a technical level is it does not scale. Knowledge and

"someone who is technically very curious." By far the most useful quality in a CTO, but I'm a CTO and have said that exact thing so I'm biased. I have met hundreds of CTOs in my career so far. It is surprising how quick

2? I have 12 APs in my house. 5 ghz propagation is terrible through insulated walls, especially those with metal film and 5/8's drywall. Add the green stuff and a closed door and APs multiply.

I like it. I use Ubiquiti gear for most of my homelab and home networking stuff with the exception of the 40g and 100g stuff. It is both easy to use and provision as well as easy to upgrade… and of course it works. Sometimes people do re

Nice... I did that same problem as it was a numberphile episode. Very cool! Fortunately I have over a PB of local storage at home which helps out.

My current method is O( (n/h)^2 ) where h is the hash size, which is really O(n^2) for n>>h. I'll have to think about this to see if it would be better.
