It's not so much "constantly leaving it plugged in" as "constantly leaving it at a high state of charge" (near 100%) which naturally follows from the first.

In recent versions of iOS and macOS, Apple have added features to keep the battery at 80% charge as much as possible for this very reason - it massively extends battery life to not be at 100% all the time.

There isn't a standard that is broadly-adopted, but NUT (https://networkupstools.org/) has reverse-engineered drivers for nearly every UPS out there, usually each brand has their standard so as long as the brand is supported it will work. (NUT is also what TrueNAS, Synology, QNAP, etc use internally for their UPS support)

I've had good luck with using NUT with APC UPSes (both consumer models and buying used enterprise rack-mount models).

One cool thing you can do with NUT is share the UPS state over the network, so that multiple machines can respond to the power state instead of just the machine that is plugged in via USB directly.

Yeah after doing a bunch of testing what I settled on was a used ThinkCentre Tiny with a dual 10G NIC running OpenWRT, and then a cheap Chinese PoE switch with 4x2.5G ports and 2x10G SFP+ ports. Router and my main computer on 10G, NAS and Wi-Fi (UniFi AP that I've had since before) on 2.5G, and then everything else is on a separate 1G switch.

For a home network, 2.5G LAN is really the sweet spot. The hardware is affordable now, the spinny drives in my NAS can't realistically do more than 200 MB/s for a real workload, there are no single-stream downloads online that are going to be faster (the fastest "normal" download I've seen is 2Gbit from Microsoft)

I just got upgraded to 10 Gbit internet the other week and was looking at routers, and it seems to be a surprisingly common configuration (or routers with 10 Gbit WAN and 2.5 Gbit LAN ports). I think router manufacturers are banking on 99% of people only caring about Wi-Fi and then being fooled by those "up to 7000 mbit over wifi!" numbers. And then due to scale those are the only chipsets that are affordable.

Another reminder to developers to not bother with public APIs, just screen-scrape or reverse-engineer the official app private API.

When I was following Synology communities closer, the common wisdom was that the expansion units weren't great in either performance, stability or cost, and you were better off buying a new, bigger unit and then selling your old one used to recoup the cost difference.

I'm also in the same position, I have a DS918+ that is full. It's also 6 years old and probably on the tail end of getting software updates so I'm weighing my choices...

The cheaper aliexpress item you actually want is this one, it will read the emarker and tell you the power/data rates it supports, if it supports thunderbolt etc https://www.aliexpress.com/item/1005007287415216.html

The really janky ones you get with like USB gadgets like fans only have the 2 power lines hooked up and not the lines needed to communicate PD support, those will work exactly the same as the same janky USB A-microUSB cables they used to come with, supplying 5V/2A. You throw those away the second you get them and replace them with the decent quality cables you bought in bulk from AmazonBasics or something.

True but pretty much the only devices that need those are high-end SSDs and laptop docks and in both cases you just leave the cable with the device rather than pulling it out of your generic cables drawer.

 

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?
