Note that PyCharm and mypy's semantics differ in some key ways: https://youtrack.jetbrains.com/issue/PY-54411/Type-checkers-... . https://youtrack.jetbrains.com/issue/PY-24834/Support

The reason is that the community decided they needed some form of type annotations, but nobody could agree on which ones or how they should work. So some syntax was added just so the parser wouldn't fall over, but the semantics were le

The usual cases are scroll positions, selected text, form fields, event handlers, basically any state that isn't naturally captured in the HTML text. That's where the VDOM differ comes in handy, by modifying existing elements and

wgpu supports both a SPIR-V passthrough mode [0] and a regular SPIR-V mode where it will get some transformations added to it (e.g. bounds checks are added on backends without VK_KHR_robustness). I don't believe Dawn has a similar pass

Frenet frames are simply any orthonormal frame. A rotation-minimizing frame is a frame that has minimal twist from some previous frame.

Yeah, I don't understand the disparaging of 4-bit ADPCM as being terrible quality when this is effectively a 3-bit ADPCM. Most ADPCM codecs I've seen shipped have a similar table based system with a frame header with coefficients

The galaxy is billions of years old. Human civilization is a few thousand. Human civilization with a significant radiometric footprint above noise is less than a hundred. And there's some not unreasonable concern that if we don't

There were a lot of people that left Python for other languages and never came back in the whole 2 to 3 debacle. It doesn't help that the early versions of Python 3 were really opinionated and terrible. Python 3 only took off after the

Personally, I see elevating Fabrice Bellard to this godlike figure that nobody else can possibly touch as insulting to the whole rest of the multimedia community who helped maintain ffmpeg. Fabrice didn't touch ffmpeg past the first co

The only consistent thing yet hear about the FAANG interview process is how universally bad it is, but also how you should just play along to get your $300k/yr salary.

The easiest way to describe matrix multiplication is nested function composition. f(x) = 2x g(x) = x + 5 It should hopefully be obvious that "nesting" the two isn't commutative: g(f(x)) = (2x) + 5 = 2x + 5

TCP/IP does not use the OSI model. Stacking layers on top of each other promotes inefficiency and poor security, and is one reason why TCP/IP won over the OSI-recommended protocols.

Yeah, if it wasn't for the improved developer velocity of these fancy new JavaScript frameworks, we would have been left with a basic HTML version of the widget that doesn't require any JavaScript and has all the same features. Un

Worth noting that there is a spec for the custom XML file, it's known as FXG. S starts a cubic Bezier curve in absolute coordinates: https://web.archive.org/web/20110611002637/http://opensource...

It's worth noting that Python str's are sequences of code points, not scalar values. This was a truly horrendous mistake made mostly out of ignorance, but now they rely upon it in surrogateescape to hide "invalid" data,

I have a MacBook I use occasionally for work. I don't have an AppleID and don't want to make one (same as Microsoft Account). Every time I boot the system, there are about 20 untagged login prompts and have to manually cancel.

The simplest way I know of to make a discriminated number type in TypeScript is: declare const isRobotID: unique symbol; type RobotID = number & { [isRobotID]: true }; and now you can cast a number to a RobotID and back.

I really wish that int arr[5] adopted the semantics of struct { int arr[5]; } -- that is, you can copy it, and you can pass it through a function without it decaying to a pointer. Right now in C: typedef uint32_t t1[5]; typedef st

You do as much of that offline as possible. The "split them into micropolygons" happens at editor time, along with a search tree that makes it really easy to find them. It's still very demanding! But the goal is that you bake
