  1. Re:I thought.. on Home Improvement Chains Accused of False Advertising Over Lumber Dimensions (consumerist.com) · · Score: 3, Insightful

    I know fuckall about wood, but if I plan something where I use a 2x4, I used the dimensions 2x4xh on my plan, I want 2x4.

    Right, for that you have to look up what the material is and get the dimensions from the datasheet. Or in the case of lumber, a website explaining the basics of it. You want 2"x4" and you go to the cabinet shop and they explain to you to buy 10/4 4s4 that is 4" wide and it will be 2 5/16", but they can plane it down for you for cheap/free. They might not have 10/4, you might have to choose between 8/4 which is 1 13/16" or 12/4 which is 2 13/16".

    If it is 13/16" or thicker, then then it will be labeled in 4ths where 4/4 = 1" and describes the rough thickness before planing. But you can't get an exact thickness by buying it rough, because then it is rough and isn't exactly that thickness. It has to be planed to have exact dimensions. And then it is 3/16" thinner than the starting thickness. But sawmills don't cut anything less than 1", so you won't normally see 3/4 or anything like that, instead they would start from 4/4 and plane it all the way down and give you an exact measurement. So 1/2" is really exactly 1/2".

    You aren't fucking with 2x4's anyways if you don't know anything about wood, because that is a specialty product for framing.

    You can basically never design a physical item before you make it and not have to know anything about each material. Doesn't work.

    You can always wait until after you have a pile of parts, measure them, examine their properties, and then design it without having had to actually learn anything. It might be harder to get the correct parts into the pile that way though, or to repeat the process and build 2 that are the same.

    The vast majority of parts and materials are sized slightly larger or smaller than the printed size, which is actually a fitting size not the exact size of either side of the fitting. It is almost always greater than, less than, or started as before finishing.

    Reading comprehension matters, too.

    Also, not very much in a datacenter is encrypted. Intel has enhanced AES because they have enterprise remote management that has be encrypted and runs outside the main CPU cores. So it is more built-out.

    Cost generally is for a specific level of performance and heat. It is like Ohm's Law, you can't separate the parts. Different sides of a die.

    As far as compatibility, you have to buy a motherboard for one or the other, and everything else works the same. That's a complete wash, and has been since the EISA bus went out of fashion.

  4. You ran left, you ran right, you ran right around all of it.

    That bugs are expensive does not mean that a bug can't be built into a tube amplifier. You're engaging in magical thinking to disprove the possibility of a device that actually exists, and that you simply don't know about. Weak. But weaker is that you ran left, you ran right, you ran right around all the specific factual claims and just waved your hands each time.

    Don't blame him, it the neckbeard talking. Everybody knows that once a neckbeard attaches to the central nervous system it cannot be removed from the host without killing them both. They're symbiotes now.

    The good news is, neckbeards are biologically compatible with ewoks. So there is some hope for a semi-normal life.

  8. I don't doubt you worked in a building where those activities were being done, but this isn't even a hard problem. You're trying to wave around some sort of authority chode, but argument from authority is crap. And you're not even claiming experience; "I did work I thought was important, a long time ago, therefore I know all about modern materials engineering." It is really weak sauce.

    What is really really weak about the Peltier cooler idea is that, as with all heat exchangers, there is a net increase in heat. So if you're hiding it entirely inside another device, you're only adding another heater. The bottom of the plug socket is likely to be thermally insulated to prevent the heat from leaking into the rest of the device, so there is just no way. You'd do better with just air cooling.

    If you're wondering why an IC from radio shack might not handle that temperature it is not because of the circuit, the part that does the work, it is because of the cheap plastic package it is in. Most ICs are also available in ceramic packages. Typically that means it is rated to 210C ambient. And with good thermal shielding, it isn't going to get that hot because only one side of the application package would be that hot. If ambient inside your amplifier is getting to 200C you have other problems. The base of the tube's plug doesn't get that hot, and the reason is because it has a high temperature plastic washing in between. So you if put a flexible printed circuit (made of kapton, good to 260C) with a ceramic IC somewhere inside of some plastic whose purpose is already thermal shielding, then it is safe to assume that that circuit will be somewhere in between the temperature of the tube, and the ambient temperature. And it isn't going to melt or burn.

    And no, you can never put a new whatthewhat into an audiophile's favorite amplifier without losing a fatal number of style points. So that is a given.

    You could fit it inside a plastic washer, antenna and all. The power pins have to pass through the washer.

    Luckily, radio emissions are detectable so it wouldn't be worth the effort. But don't assume the old stuff doesn't have room for new tricks.

  14. Then the device will refuse to function.

    It is just current through nichrome wire, they're not going to stop the internet from being full of mods to make it function.

    It is just not doable. You can make an electric toast timer with a "light/dark" dial from parts in a junk bin; a 555 timer, a capacitor, 2 resistors, a relay, a potentiometer, done.

    On 64bit systems we're good until December 4th, 292277026596.

    But keep in mind, 32 bit timestamps are signed, not unsigned. This is important when constructing things like HTTP cookies when you want the maximum time, which is going to be 0x7fffffff.

    The good news is that most programs that blindly trust that signed 32 bit value will just think it is 1901, there is no reason they would crash. Most of the servers and things that having calendar-aware timing that would set up a crash situation will have already been updated to 64 bit systems by then. Few appliances use dates in that way.

    No no no. Simply switching to a 64 bit linux will be enough for linux users to avoid the bug; a switch most already made.

    The problem is going to be appliances, not just linux but *BSD too. And combined, the *nixes make up the majority of appliance computers, and many are 32 bit.

    All sorts of things from routers to air conditioners might stop working. Or at least, operate at the wrong times until somebody changes the date.
