  • For SSD’s, it’s 100% a logical table, because data is stored all over the place for load balancing purposes, so it already uses a logical table to keep track of what each block is for at any given point in time.

    For HDD’s, historically they were physically separated, and they mostly are still, but there’s still a logical table, and there’s no reason the logical table can’t say “Blocks 0 through 1234 and 2000 are part of partition 1” if you have something somewhere else that you want on that partition.



  • From the other side: I’m pro-union, but at my workplace I’m management.

    One of the guys on my crew is terrible at his job. Just awful. Everyone hates working with him, he doesn’t get anything done on time, he’s either stupid or willfully ignorant, the list goes on and on.

    The union, however, has negotiated that I can’t action for productivity. It literally doesn’t matter how badly he does his job, as long as he’s in his spot and something is happening, I can’t do anything. On top of that, this guy has seniority over most of the other guys on the crew, so I can’t even give him less hours without cutting the people who actually get shit done.

    It’s incredibly frustrating, and the only thing I can do is watch his attendance like a hawk in the hopes I can get rid of him for being late one too many times.



  • Make sure your litter box is clean, and that your cat thinks it’s clean. Cats want to be able to bury their waste, and if there’s too much in the box for the cat’s liking, they’ll go somewhere else, and it’s often right outside the box if there isn’t something else they could use. It’s important to understand that it’s the cat’s opinion that matters here, not yours: you may need to scoop it every day, even if there’s only a little in it.

    You may also need to move the litter box and clean the previous area, including and most importantly the place outside the litter box that gets used. Use vinegar if you can: it has a strong smell that cats don’t like, but it won’t hurt them like bleach can. Lemon juice works well for this, also. What this will do is make sure that this area doesn’t smell like a place they have used as a litter box before.



  • Question 1: These surfaces are defined by having seams. So would it ever be right to rate them as ‘seamless’?

    I would say that something like cobblestone could be called seamless if the overall ‘pattern’ flows throughout, and there isn’t any obvious place where it breaks. It’s not so much “more than the expected number” of seams, because there would be a seam there anyway, but a bigger picture idea of two separate stretches of cobblestone pattern meeting versus one unbroken cobblestone pattern.

    Question 2: Tactile paving for blind people. Does that make a surface rough for you? In a way, that’s literally how this paving becomes tactile, right?

    Yes, it’s rougher terrain, by definition, because it’s less smooth.

    Question 3: A pedestrian crossing going over a traffic isle (but marked as one continuous path). Assuming otherwise perfect surfaces, does it have ‘cracks’ (since it goes over 4 curbs), and a ‘rough surface’ if it has tactile paving?

    It has rough surfaces and smooth surfaces. Since the surfaces are otherwise perfect, they have no cracks.

    Question 4: The marked entitiy is a wide area, not a narrow path. You’re asked to rate it’s surface quality. The area is mostly flat and smooth, but has some cracks and potholes in a few localized spots.

    If there are cracks and potholes, it’s clearly not perfect, so don’t rate it as such regardless of the ease of finding a path. It’s also not bumpy, because it’s flat and smooth. You should rate it something like “mostly flat and smooth, but has some cracks and potholes in a few localized spots.” Probably 4/5, going off your description.





  • Well, think about it.

    WiFi is electromagnetic radiation, and penetrates walls. The standard frequency is 5 GHz. With harmonics, we should expect similar behavior from wavelengths that are some whole-number multiple of this frequency.

    There are multiple such frequencies within the visible light spectrum, such as 500 THz (orange), but visible light doesn’t usually penetrate walls, it’s instead reflected or absorbed.

    On the other end, we have X-rays, which are in the range of 3×10^(16) - 3×10^(19) Hz, which are used medically to see into the human body. There are likewise whole-number divisors, such as 200, which put a potential fundamental at around 600 THz (green). Yet, we generally can’t see through people using normal light. That’s why we use X-rays.

    Now, this is all well and good, but it’s all purely academic, because the reason why you can’t use your infrared sensors to detect the color blue or purple is because the infrared sensors aren’t sensitive in that frequency, the same reason why you can’t use your blue cones to detect infrared.
