    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.








  • 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.


  • It’s not entirely true that you can’t identify him from that Facebook account. It’s just really, really hard.

    Facebook almost certainly knows who he is. Like specifically, name and all. Their data mining is VERY extensive, and he likely has other accounts.

    Anyway, with a lawyer’s help, you can (possibly) get a court order for Facebook to reveal what they have on the guy. They certainly have things like IP addresses and timestamps, but they also probably have name, other associated accounts, viewing history across the web (from those “share with Facebook” icons/links, even if untouched), and hundreds or thousands of additional pages.

    Is it worthwhile? Probably not. But it can be done.





  • While the AG has a number of options available, most common are civil suits. But even before that, simply having the AG in the middle is putting them on notice that they need to really, REALLY be confident that they are in the right. In most circumstances, they will simply approve your warranty claim to avoid the risk.

    When you see headlines of “[state] AG sues XYZ Corp for not honoring warranty claims”, it means there have been a ton of complaints, or a lot of complaints where they still refused. You should never purchase from a company that’s had one of these headlines recently.


  • Adding onto this, every state AG regularly pursues companies for not honoring their warranty. It takes some paperwork (usually original purchase receipt, original warranty terms, and your desired resolution), but it’s usually not too bad. Yours might even list it as a common category for your complaint. Probably takes about 20 minutes.

    Companies don’t usually fuck around when the AG is watching. You probably aren’t the only one to complain, and too many complaints can lead to a full-blown lawsuit from one of the most capable organizations in the state. The penalties can include your entire company - including parent, children, and sibling companies, being banned from doing business in the state.


  • This one is tough. A longer warranty is a way to reassure customers that it’s made better, with the promise that it will be repaired/replaced if it breaks. And if they honor their warranties as promised, it’s probably valid. Warranty claims are expensive, regardless of industry, so they go to great lengths to minimize claims. Whatever the warranty is, you can reasonably be sure that it will last that long, but probably not a second longer. Again, assuming a trustworthy company that will honor the warranty.

    Otherwise, anyone can shit in a box and mark it guaranteed. If it’s from Amazon/AliExpress, the company probably won’t even exist in 6 months (but a strangely similar new company will).

    The flip side is that an unusually short/weak warranty, below that of its competitors, is almost certainly a shit product. They aren’t even going to pretend it’s up to industry standards.


  • This is part of a series frequently known as “Microsoft interview” questions. The most famous one is, “Why is a manhole cover round?” They are partially meant to gauge your problem-solving abilities, but more importantly see how you react to a question you did not (and could not) prepare for. They’ve since fallen out of fashion, because it was always a terrible way to gauge roles like software developers.


  • During US prohibition, there were “grape bricks” with warnings not to dissolve in water and place in a cupboard for 20 days, because then it would turn into wine.

    A simple negation probably won’t cut it legally (the bricks had a significant legal purpose), but you could probably word it in a similar way. For instance, “While VPNs are effective at anonymizing yourself during piracy, they can also protect your privacy from data mining ad companies”.

    At some point, you’ll have to conspicuously avoid the topic and let people infer. Remember when high-speed connections were advertised as being great to “download movie trailers”?
