Any hard drive can fail at any time with or without warning. Worrying too much about individual drive families’ reliability isn’t worth it if you’re dealing with few drives. Worry instead about backups and recovery plans in case it does happen.

Bigger drives have significantly lower power usage per TB, and cost per TB is lowest around 12-16TB. Bigger drives also lets you fit more storage in a given box. Drives 12TB and up are all currently helium filled which run significantly cooler.

Two preferred options in the data hoarder communities are shucking (external drives are cheaper than internal, so remove the case) and buying refurb or grey market drives from vendors like Server Supply or Water Panther. In both cases, the savings are usually big enough that you can simply buy an extra drive to make up for any loss of warranty.

Under US$15/TB is typically a ‘good’ price.

For media serving and deep storage, HDDs are still fine and cheap. For general file storage, consider SSDs to improve IOPS.


When you download a torrent, you’re downloading it from someone else’s computer. That ‘someone else’ is usually an individual, not some file sharing site with redundant servers.

When you download a torrent, someone had to send it. It’s a small cost for individual torrents, but they had to pay for energy, internet connection, hard drives etc. If more people seed the torrent, you get a small bit of it from each seed, spreading the burden.

If no-one with the torrent has their computer on and seeding it, you cannot download the file, because there is no-one to download it from. If there are several seeds with the torrent, then you can still download it even if one or more seeds turn the computer off at night, delete the file, or are overloaded.


I’ve certainly never heard of a chicken ranch, but plenty of chicken farms.


Indeed, the US has a major lack of fixed-line competition and lack of regulation. Starlink doesn’t really help with that, at least in urban areas.

I’m not familiar with the wireless situation. You’re saying that there are significant coverage discrepancies to the point where many if not most consumers are choosing a carrier based on coverage, not pricing/plans? There’s always areas with unequal coverage but I didn’t think they were that common.

Here in NZ, the state funding for very rural 4G broadband (Rural Broadband Initiative 2 / RBI-2) went to the Rural Connectivity Group, setting up sites used and owned equally by all three providers, to reduce costs where capacity isn’t the constraint.


Starlink plugs the rural coverage gaps, but in urban areas it’s still more expensive than either conventional fixed-line connections or wireless (4G/5G) broadband. Even in rural areas, while it’s the best option, it’s rarely the cheapest, at least in the NZ market I’m familiar with.

It also doesn’t have the bandwidth per square kilometre/mile to serve urban areas well, and it’s probably never going to work in apartment buildings.

This is a funding/subsidisation issue, not so much a technical one. I imagine Starlink connections are eligible for the current subsidy, but in most cases it’s probably going to conventional DSL/cable/fibre/4G connections.


Aggregate bandwidth now rivals or slightly exceeds gigabit wired connections.

Where that aggregate bandwidth is shared amongst large numbers of users, bandwidth per user can suffer dramatically.

Low density areas may be fine, but cube farms are an issue especially when staff are doing data intensive or latency sensitive tasks.

If you’re giving employees docking stations for their laptops, running ethernet to those docking stations is a no-brainer.

Moving most of the traffic to wired connections frees up spectrum/bandwidth for situations that do need to be wireless.


Secondhand stuff can be really cheap if you know where to look, but the drawbacks are usually power and noise.


I wouldn’t start worrying until 50k+ hours.

There should be a way to view SMART info and that includes an hour count.


You’re also potentially blocking a seat that could be used by a paying passenger, and the operator will statistically run more/longer trains at higher cost to cope with increased demand.


Hmm. They’re very common in NZ now, however it appears that document is talking about modulating the actual normal shop lighting, not just an independent transmitter.

I redid the electrical in a supermarket already fitted out with Pricer gear, and we went from dumb electronic-ballasted fluoros to dumb-driver LEDs, no DALI and certainly no comms uplink or modulation smart enough for that. I’m aware that the document suggests power-line communication to the drivers, but these were off the shelf dumb drivers/ballasts.

The ceiling mounted Pricer transceivers would have been doing all the transmitting, and as I never saw any visible light coming out of them, and the HF ripple and instability from the shop lighting would have been significant, I think it’s pretty safe to say they were using some form of IR.


Yup. They use ceiling-mounted IR transmitters that are a bit like a big multi-directional TV remote control.


FYI: This has been going on for about a month. If you still see warnings, update your ad blocker, switch to UBlock Origin, and/or check their FAQs.


Assuming the setup ends up similar to how it is in NZ, the barrier to entry to either found a new ISP, or for an existing ISP (even from another area) to set up shop, is really really low.

We now have far too many fibre ISPs and resellers to keep track of - a few dozen. It’s like the days of dial up.


Yes, or at least 9 when the seed numbers were last checked, which shouldn’t change too quickly.

As for why seed numbers listed on trackers are significantly larger than those found by actual clients, who knows.


Not all seeds are online 24/7. Sometimes leaving the torrent running for hours or days can allow you to download it when that PC/server gets switched on.


But how do you determine what’s just ‘fixing poor wording’ and what’s actively hiding major bias or retcons of history?

Radio NZ got caught a year or so ago with a staffer who was editing articles syndicated from Reuters to be more pro-Russian. Should they be able to sweep that under the rug and claim it was only ever the one article they got caught on?

Likewise, bin Laden was originally hailed as an anti-Soviet freedom fighter. The articles relating to that are part of the historical record and kinda important.

Allowing the historical record to be retconned with impunity was probably the defining trait of 1984. It’s really not a path you want to go down.
