In Japan they have an IR beacon system to track traffic congestion which works anonymously and lets offline car navigation systems have good-quality traffic info.

I picked up a used 2018 Fujitsu office PC with an i5-7500 for $60 (from a physical recycle shop, with a 14 day warranty) and it draws 15W idle. Way better value than a Pi (once you've added case, cooling, PSU etc) for running home server stuff.

A Pi still kills for "Arduino plus plus" use cases where you need the size, GPIO or can optimize the heck out of power usage on a battery.

iOS does have an API for apps to record the screen throughout the OS these days through Broadcast Extensions, but it has to be user-initiated through the control center screen recording toggle (where they then get to pick what app to record the screen to instead of just saving as a video), it wouldn't do that people think the T-Mobile app is doing

  1. I do have 10 Gbps, I pay $35/mo here in Japan (not even a big city like Tokyo, this is a depopulating, rural capitol)
  2. More importantly, even my 5 year old, 4-bay spinning rust Synology NAS can saturate 2.5 Gbps copying files. With soldered storage in modern machines, faster networking is cheaper than replacing my whole machine

Yeah what I've settled on is one of those $40 generic Chinese 4x2.5G PoE+2x10G SFP+ switches. Gives me:

  • 10G for internet/router
  • 10G for my main computer
  • 2.5G for secondary machine
  • 2.5G for NAS
  • 2.5G PoE for WiFi
  • One port chained to a 16-port Gbit switch for all the slow junk that doesn't need performance

Would be great to get another 10G for the NAS as well!

For what it's worth, Synology Hybrid RAID is just a fancy GUI over linux mdraid, so the drives can be mounted on any Linux system (Synology even have instructions for how to do this on their website). You'll be SOL mounting them with any kind of third-party NAS GUI that expects their own partition layout though.

What are you powering with it?

You plug it straight into the wall, it syncs to the grid and back-feeds it, up to 800W. Your meter stops spinning (or even goes backwards)

[–] [email protected] 5 points 1 month ago* (last edited 1 month ago)

because if the grid went down, these types of panels could keep feeding the house, out to the street, and electrocute a line worker

The inverter in these is designed to shut down if it doesn't detect a waveform from the grid to sync with - they are unable to create a 50 Hz AC wave on their own. As long as the hardware is legit (which is a big if with how easy it is to get unsafe junk in from China) there is no safety issue, it's purely regulatory.

Yeah when I went over my bank statements for last year, I only went to an ATM a single time in the whole year. Mostly only need cash for stuff like parking

The VGA plug in OP is part of a series and I bought all three, including the SCSI one (which is objectively the best one)

 
 

My internet connection is getting upgraded to 10 Gbit next week. I’m going to start out with the rental router from the ISP, but my goal is to replace it with a home-built router since I host a bunch of stuff and want to separate my out home Wi-Fi, etc onto VLANs. I’m currently using the good old Ubiquiti USG4. I don’t need anything fancy like high-speed VPN tunnels (just enough to run SSH though), just routing IPv6 and IPv4 tunneling (MAP-E with a static IP) as the new connection is IPv6 native.

After doing a bit of research the Lenovo ThinkCenter M720q has caught my eye. There are tons of them available locally and people online seem to have good luck using them for router duties.

The one thing I have not figured out is what CPU option I should go for? There’s the Celeron G4900T (2 core), Core i3 8100T (4 core), and Core i5 (6 core). The former two are pretty close in price but the latter costs twice as much as anything else.

Doing research I get really conflicting results, with half of people saying that just routing IP even 10 Gbit is a piece of cake for any decently modern CPU and others saying they experienced bottlenecks.

I’ve also seen comments mentioning that the BSD-based routing platforms like pfSense are worse for performance than Linux-based ones like OpenWRT due to the lack of multi-threading in the former, I don’t know if this is true.

Does anyone here have any experience routing 10 Gbit on commodity hardware and can share their experiences?
