Because they know they can blame it on the other party. And people will eat it up.

Seagate was my go-to after I had bought those original IBM DeathStars and had to RMA the RMA replacement drive after a few months. But brand loyalty is for suckers. It seemed Seagate had a really bad run after they acquired Maxstor who always had a bad reputation.

Our first computer was a Macintosh Classic with a 40 MB SCSI hard disk. My first "own" computer had a 120 MB drive.

I keep typoing TB as GB when talking about these huge drives, it's just so weird how these massive capacities are just normal!

Yeah our file server has 17 Toshiba drives in the 10/14 TiB sizes ranging from 2-4 years of power-on age and zero failures so far (touch wood).

Of our 6 Seagate drives (10 TiB), 3 of them died in the 2-4 year age range, but one is still alive 6 years later.

We're in Japan and Toshiba is by far the cheapest here (and have the best support - they have advance replacement on regular NAS drives whereas Seagate takes 2 weeks replacement to ship to and from a support center in China!) so we'll continue buying them.

In addition to needing to fit it into the gear you have on hand, you may also have limitations in rack space (the data center you're in may literally be full), or your power budget.

That marketing copy is just amazing.

First of all, acknowledging that the blimp is "incredibly wacky"

Then trying to sell the fact that it doesn't float, mount or have any powered features as "Just you and good clean fun!"

What I read is that US Steel doesn't feel there's a payback in investing in refurbishing the blast furnaces to keep them going, and want to move to other methods of steel production (apparently something called EAF is cheaper and more eco-friendly), and these would not be in Pittsburgh.

Nippon Steel OTOH still believes there is money in renovating and continuing to run the blast furnaces with the current staffing in place, so the unions who support the current workers are in favor of this.

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.

Noun PC (countable and uncountable, plural PCs)

Initialism of personal computer.

A personal computer, especially one similar to an IBM PC that runs Microsoft Windows (or, originally, DOS), usually as opposed to (say) an Apple Mac.

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)

 

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?
