    Not too much to put into a formula, just a lot of stuff to account for. I'd love to see someone (who has access to the necessary equipment) try to approximate a chip's max stable clock, the math involved must be fun.

    Well, it is. You just have to destroy the chip to get all the parameters. I wonder if the inspection tools at big fab would even be able to gather the necessary information...
  3. Like maths, where there's only one right answer? *chuckle* What you appreciate about math and science is that the solutions are mechanical and easy to verify, and while that doesn't hold all that well in advanced topics, it's invariably true in comparison to language. Problem is, in order to consistently grade language-based work, they've come up with some very specific systems that condense everything down to an arbitrary and disjointed set of parts, while the rest is still subjective bullshit. There's no way to properly evaluate language-based academic work the same way you can with math and science, and until people realize that, we have to deal with their pitiful and misguided attempts. Basically, it's stupid people trying to make a completely subjective thing fit on a scale and only succeeding to make the subject utterly worthless.
  4. Is that a... A regular, house door? With a regular knob?
  5. I'd say that it's irrelevant at this point because it made assumptions about component density and computing power over time that just haven't held up. It's not like standardized units or anything where even if it's not the best definition we need something, it's just a conjecture that doesn't work anymore. EDIT: Reading about it, while it's fallen apart in the last decade, many people (a couple notable ones in the semiconductor industry) say that Moore's Law is still valid just as it was every other time it was challenged. That's a bit short-sited because current semiconductor technology can only support down to a 5nm process node with current projections, and it's certainly getting exponentially more difficult to make those leaps. Essentially, traditional microprocessors follow a logarithmic growth curve, where Moore's Law supposes an exponential one. We're currently at what looks like an inflection point, and will need some other technology for the same advances we've seen. One possibility is heavily multi-layered architectures, but it'll be a long time before we've resolved the heat, power, and manufacturing issues to the point where we can make fully 3D high-performance processors, not to mention the fact that just having more circuitry can't make single-threaded performance substantially better than it is at this point. The rest is either theoretical or very, very experimental.
  6. Only meaning I can find is "school," which makes me wonder what school he goes to where he would decide to use that shortening. @IAR117 Not really. Doubling your component density on the same basic technology only works until you start dealing with quantum mechanics, and microarchitecture is (I think) the only widespread technology where we're at that point.

    Work

    I think they're still looking for coders for Floatplane. If you're good with coding, might try pursuing that. Not sure why they'd hire someone just to hire someone, though.
  8. They basically fixed them after the Haswell 'hiccup' generation. I haven't used an Elitebook to compare, but the only thing I find wrong with my T450s's touchpad is Synaptics, which isn't there with their newer ones.
  9. It gives you the system of DEs, so from there you find the eigenvalues and their associated eigenvectors for the coefficient matrix (also given) and use them to construct the solutions for the system. For each distinct eigenvalue λ and its associated eigenvector v, [x(t),y(t)]=veλt is a solution to the system. As the system is linear, every solution can therefore be expressed as a linear combination of those two solutions; [x(t),y(t)] = C1v1eλ1t + C2v2eλ2t The given answer supposed that [x(t),y(t)]=vt is a solution to the system, which is obviously incorrect because that would mean that x(t) and y(t) are linear functions. What is correct about the given answer is that every 2D vector can be expressed as a linear combination of the eigenvectors, because the eigenvectors are linearly independent and therefore form a basis for R2. That's linear algebra, though, so it's not relevant here.
  10. ... This confuses me.
  11. 1: For the line to go with the flow, it must be a solution to the DE. The given (incorrect) answer is a superposition of only the vectors, not of solutions. 2: A linear system is linear with respect to each function and its derivatives. Taking the first one as example: sin(x)+4.9y is nonlinear with respect to x as sin is a nonlinear function. -2.3x+.4y is linear. Because part of the system is nonlinear, the system is nonlinear. EDIT: Sorry again for the wait, I hate taking so long.

    midnight thought: if i'd be leader of a country…

    Yeah, it should just be illegal to use your name, regardless of the length. Your name can be part of it, but the name at least has to say something about the company's purpose.
  13. Makes sense. Can't hold stuff if you don't know what it is.
  14. Well, to start, that's a right triangle on top of a rectangle. The interior angles of a triangle sum up to 180, and since it's a right triangle you know that the third angle is 90 degrees, and you also know that the bottom angle is actually the angle in the triangle plus the angle in the rectangle. That lets you construct an algebraic equation that you can solve for X, then just plug it into the expressions for the angles.
  15. Might be better to use Google forms. People generally don't like to sign in for questionnaires. Personally, I can't fill it out because my Microsoft account password is the only password my mind refuses to keep.
  16. When did she become a dog? Is that the purpose to this? Is this a PSA about befriending dogs?

    Math help

    What exactly does it want from you? 10 and 12 are already factored sufficiently to find the solution. Does it want you to put it in terms of other trig functions?
  18. An iFixit toolkit, a CS GI Tanto, pencil lead/erasers, a couple figures, a set of TWC sonic screwdrivers, an amount of papers that makes me want to burn everyone at school who gives them to me with every flammable object within twenty miles, water bottles, a cactus, all the knives that people gave me to sharpen, and some 30 or so cubes. EDIT: Oh, and a torch.
  19. They shouldn't though. I'm not saying anyone who doesn't get them is an idiot, but there is definitely some exceptional factor. I'd say it's that they, from most to least likely, were poorly taught, are very young, or are mentally challenged in some way (I've only ever met one person who fit the last one). Reason being, since "per" indicates division, "of" indicates multiplication, and "cent" is a number, "X percent of Y" is literally the mathematical expression you use. Every time you say it, you're reciting instructions on how to handle it. I guess it could also be that English isn't the person's first language (if they know it at all), in which case the phrase might not be so explicit.
  20. There is indeed a programming section. And when he asked about the language, he meant the programming language. Also, it would be nice to know what precisely you need help with. "I need help" isn't descriptive enough for us to actually do anything.
  21. Well that's fallacious. I don't buy into the "a weird name will destroy your kid's life because bullies will pick on it and drive them to suicide blah blah blah" stuff, but there's a certain range where the name absolutely will inspire the joke. I remember hearing the administrator at my high school call a "Clifford Fomit" to the front office. If people were to pick on that kid's name, would you say that the name itself had nothing to do with it? There was also a kid at a dissection summer camp named "Kenny." Sounds pretty unremarkable, sure, but every person he was introduced to made a forced "OH MY GOD HE KILLED KENNY" joke, and the completely flat and robotic way he reacted made it abundantly clear that he got that a lot. Nothing else about him, just his name did that. Now, for a name like Calculus, the general reaction will just be "well that's odd," but he'll probably silently want to punch everyone in the room every time he hears an "I was doing Calculus" joke by the time he's 15.
  22. It's an iBook M6497, those use PPC 745/750/755cxe chips.
  23. I agree. People should be able to play games with whatever they prefer, no reason to force someone to use something they're not comfortable with. It's all just for fun. Problem is, devs have gotten into some really stupid habits. So many games, even games where controllers make no sense (almost every FPS), just have the mouse and keyboard parts thrown on haphazardly, and it can be annoying at best, game-ruining at worst. In the worst of Ross Scott: "It doesn't matter how good the game is, if the controls feel like you're steering with your elbows, it can ruin almost any game."
