- Comment on The Raspberry Pi 5 is no match for a tini-mini-micro PC 5 months ago:
I would add:
- if you wanted direct and low-latency access to cameras (for machine vision)
- Comment on ZFS High Availability with Asynchronous Replication and zrep 6 months ago:
Thanks, that looks like something I might have to try. :) Myself, over the network, I still don’t do filesystem level incremental backups, sticking to either directories or virtual machine snapshots (both of which have their shortcomings).
- Comment on ZFS High Availability with Asynchronous Replication and zrep 6 months ago:
I’ve been hearing about ZFS and its beneficial features for years now, but mainstream Linux installers don’t seem to support it.
Out of curiosity - can anyone tell, what might be blocking them?
- Comment on Raspberry Pi 5 vs Intel N100 mini PC comparison - Features, Benchmarks, and Price 6 months ago:
From a person who builds robots, three notes:
- Camera
Raspberry Pi has two CSI (camera serial interface) connectors on board, which is a considerable advantage over having to deal with USB webcams. This matters if your industrial robot must see the work area faster, your competition robot must run circles around opposing robots, or more sadly - if your drone must fly to war. :( On Raspberry Pi, in laboratory conditions, you can access the camera (with big ifs and buts) at 500+ frames per second. That’s impossible over USB and unheard of to most USB camera makers.
- Optimized libraries
I know that Raspberry Pi has “WiringPi” (a fast C library for low level comms, helping abstract away difficult problems like hardware timing, DMA and interrupts) and Orange Pi recently got “WiringOP”. I don’t know of anything similar on a PC platform, so I believe that on NUC, you’d have to roll your own (a massive pain) or be limited to kilohertz GPIO access frequencies instead of megahertz.
- Antenna socket
Sadly, neither of them has a WiFi antenna socket. But the built-in WiFi cards are generally crappy too, so if you needed a considerable working area, you’d connect an external card with an external antenna anyway. Notably, some models of Orange Pi have an external antenna, and the Raspberry Pi Compute Module has one too.
