gct··on Salary Stream – Software Engineer Offers
Usually they specify the stock part in dollars, it doesn't turn into a concrete number of shares until after you start.
gct··on AMD is determined to gets its rightful datacenter share
I'm curious, why encrypt Netflix video traffic at all?
gct··on Peter Thiel at Center of Facebook’s Internal Divisions on Politics
Money spent by non-profits that don't have to report their donors (hence "dark")
gct··on Google Culture War Escalates as Era of Transparency Wanes
Amazon vests 5/15/40/40, even worse than you said.
gct··on Separating gifted children hasn't led to better achievement
I was in TIP. Hanging out with smart, kind kids every summer was the highlight of my year. Lotta great memories. Public school...not so much.
gct··on The hypersane are among us, if only we are prepared to look
There's a book called "The Killing Star" where humanity is wiped out by an alien species because "Why take a risk?" That's a hyper rational position.
gct··on The hypersane are among us, if only we are prepared to look
It's a canonical fact that one of The Joker's super powers is hypersanity.
gct··on AMD lands Google, Twitter as customers with newest server chip
I bought at $5.75 and held for the past 11 years...
gct··on A Commercial Path to Fusion
The magnets are on the outside of the containment vessel, their whole point is to keep the plasma in the center. What little leaks out ablates the walls of the container, it never even touches the magnets.
gct··on Peter Thiel Calls Google 'Treasonous' and Says CIA Should Investigate
Peter Thiel is a blithering idiot, film at 11
gct··on The side of Paul Allen I wish more people knew about
Remember when Gates and Ballmer tried to screw Allen out of his shares because his productivity had gone down due to cancer?

gct··on Why are 2D vector graphics so much harder than 3D?
I'd just like to say, I'm generally hard to please on software, but Blend2D is good stuff, those guys are s-m-r-t.
gct··on Configurable Memristor-Based Finite Impulse Response Filter
I write FIR filters in software all the time, it's plenty fast for what I do. Why use analog circuit elements to emulate a fundamentally digital technique? Build an analog circuit with similar filtering characteristics. You can even design it digitally and convert it to analog using the bilinear transform.
gct··on Ask HN: Best questions for an engineer to ask a CEO during a job interview?
Yeah I had a startup offer me 50K shares or something like that and I started poking at what their full diluted share count is and they hemmed and hawwed. Pass.
gct··on Show HN: A minimal FFT code
They just project a periodic signal onto a basis of orthogonal complex exponentials, what's so hard? (/s)
gct··on AWS Ground Station – Ingest and Process Data from Orbiting Satellites
Is the data time tagged?
gct··on Magit 2.90 released
Magit is one of the packages I can't live without now that I've given it an honest try. It's that good.
gct··on Why I use a 20-year-old IBM Model M keyboard
I shelled out ~$600 for two new in-box model Ms from the 80s last year, worth it.
gct··on Google Plans Large New York City Expansion
There's dozens of us!
gct··on Automatic Differentiation with Julia
Hear hear. Everyone that's making excuses for one based is wrong. You need a zero in your set of integers to form a Ring modulo N. I hereby declare everyone that wants 1 based indexing out of some naive sense of it being easier a scrub.
gct··on Ask HN: What's your favorite elegant/beautiful algorithm?
In the tradition of naming things terribly this is called std::nth_element in C++
gct··on Ask HN: What's your favorite elegant/beautiful algorithm?
Even after working with it for 15 years I still find new and interesting things about it.
gct··on Java’s new garbage collector promises low pause times on multi-terabyte heaps
x86 caches uses virtual address for indexing (physical bits for tag), so this'll increase cache pressure too.
gct··on What Was the Microsoft Network?
MFW people don't realize where MSNBC came from
gct··on Complex numbers in JavaScript
Here's an article on it that was posted awhile back: https://medium.com/@smcallis_71148/complex-arithmetic-is-com...

The gist is that you can get Nan+jNan for some operations where you wanted "infinity", so to do things their way, you have to insert a NaN check after multiplication for example. This isn't too bad by itself (it's just a bit mask), but it completely borks the vectorizer.

gct··on S2 Geometry
Yeah I guess it depends on what you're trying to optimize (they use web mercator because roads didn't meet at right angles up north for example). But if you're mostly interested in indexing physical areas with polygon approximations, it seems like having each cell be the same area would be the ideal, but idk.
gct··on S2 Geometry
I'm still puzzled why they went with 6 quad-trees, instead of doing an equal-area projection with 2:1 ratio and quad-treeing that instead. You lose a bit for half the map but you do with 6 sides too (takes 3 bits).
gct··on Complex numbers in JavaScript
They don't really, they tried to glue IEEE semantics onto their complex numbers, so they're largely broken in the modern era of auto-vectorizing compilers.
gct··on WireGuard is submitted for Linux kernel inclusion
I'd kind of like to see a screen shot of this
gct··on Fibonacci Hashing: The Optimization That the World Forgot
If you have a reasonable hash function, why is power-of-two and bitmasking bad? If you're uniformly distributed over a range N you'll be uniformly distributed over N/2
