    In the US, most protection comes from the breaker. It’s not common (or at least, not standard) to have overcurrent protection on extension cords, power strips, or even the outlet itself. And for typical wiring and uses, it usually works well enough. But it is possible to connect a space heater or hairdryer (1500w and 1800w respectively, due to the 80% rule for continuous draw) to that standard 16-gauge extension cord, or connect multiple space heaters to one circuit. Some homes are wired… Creatively… Making it easy to do. In these cases, you’re relying on the 15-amp breaker to trip, which would happen quickly. Not quite as quick, but still happens on a 20-amp. But it might melt a 15-amp receptacle first

    If it’s a 30-amp circuit, it won’t trip at all, unless the outlet melts to a short. And this is all assuming the wiring in the wall is rated for that amperage, which is implied but not stated. There are certainly a number of stories where someone upgraded the breaker to keep it from tripping, but didn’t upgrade the wiring.

    If we assume he’s talking about the wiring in the wall, this gets very simple. I once lived in a place where the upstairs bedroom and downstairs living room were on the same circuit. I currently live somewhere where a single circuit controls ALL of the bathroom outlets (multiple bathrooms), the garage, as well as outside outlets. Apparently GFCI outlets were more expensive than the entire mess of running copper all over the place.


  • This is highly dependent on what your needs are and how you plan to solve it. SATA-3 maxes at 6gbit, which SAS-2 had in 2009. Most cards are x8, and have at least 4 full speed SAS lanes (of whatever generation). That means 24 Gbit. PCIe x8 2.0 (from 2007) had 4 GB (32 Gbit). So if that meets your needs, you can run it on an ancient board.

    However, if you need something more advanced, such as SAS-3, a SAS expander, or a card with more native lanes, then you would need to plan accordingly.

    I’ve been running on an LSI 9211-4i4e, which is only a PCIe 2.0 card, for many years. I did notice my speeds dropped when I expanded the 4e to a 15-bay DAS (plus the 4 internal SATA drives), but it’s still enough to meet my needs.


  • It’s not really about 24/7, but it is about quality of components. Enterprise gear is made using slightly better parts and tighter tolerances. Things like more expensive capacitors rated for more hours/cycles, better power filters, things like that.

    The end result (and this is easily verified) is the failure rate is much, much lower than comparable consumer-grade equipment.

    There is sometimes a blurry line between what counts as enterprise vs pro-sumer vs consumer gear, though.

    McDonald’s gets the very last stage of leftover beef from the carcass. If they don’t buy it, it goes to things like animal feed.

    I don’t know how much McDonald’s-grade beef is on a cow, but I’m guessing the real numbers are how much non-McDonald’s beef people are eating, divided by the average weight of cows



  • There is a ratio, which may be a new experience if you’ve only used public trackers. It’s not really a big deal if you have some patience, though.

    TL (as do most ratio trackers) gives you bonus points for your time seeding, even if you have done nothing more than make it available. You don’t have to upload even a single byte unless someone wants it, and you’ll still get points. These points can be used to buy upload credit.

    If you simply keep seeding everything you download, and buy credits as needed, you’ll quickly have more ratio than you could ever hope to burn. No need to spend money or anything.

    As for limited content, it’s a general tracker. You probably have niche interests, so you would be better suited on a more specific tracker. I’ve almost never had issues finding anything mainstream, although quality can be a crapshoot. That’s the main reason I usually use other trackers.
