As far as I know, you can't trivially decrypt traffic as a passive observer, even if you have the private key of the website or the CA. The sides still perform key exchange using something like Diffie-Hellman. The asymmetric keys are u

I wonder what is the benefit of rewriting the libc in Rust, as most of the functions are actually unsafe. Implementing memcpy in Rust won't make memcpy any safer. As far as I understand, the main selling point of Rust is safety, so if

If you're into NT kernel internals, I recommend an excellent book "What Makes It Page?". It describes the VMM in way too much detail (in a good way). It's a great combination of theory and practice - it describes concept

You're right, I missed it. Nice catch :)

Sure: I wrote it in Typescript, modeled everything in Blender and rendered with three.js. The simulation logic itself it in https://github.com/nikital/clock/blob/master/src/mechanics.t... . That code

In real life the do align perfectly, otherwise they will get stuck. Here there are off a bit because 1. I didn't get the sizes absolutely right as I modeled it in Blender and not in a real CAD (like Gearotic) and 2. The gear simulation

Thanks for the feedback. Regarding the simple version, did you see that you can rotate, pan and zoom the camera? You can focus on the escapement to get a better view. You can also slow it down using the speed slider.

According to https://ssl.masterpasswordapp.com/algorithm.html , Scrypt is used for key derivation. Scrypt is supposed to be very expensive to brute-force. Quote: The master key is a 64-byte secret key generated by performing

Your comment regarding the gravity was really insightful for me (I didn't learn PID formally). When I put large values for i, the ball just oscillated and I couldn't see how i is useful. After I added gravity (in my local build, n

Yeah, I didn't put anything there yet, but thanks for the heads-up.

I agree, I pushed a new update. Also, I adjusted the defaults for a snappier response with a bit of satisfying overshoot

That's a good idea, I'll add them. Edit: Done.

I looked at the source of 2.7: The function PyString_Format (Objects/stringobject.c) does the formatting for the % operator. For %s it calls _PyObject_Str which in turn calls "str()" on the object. For %d it calls formatint (

Is there a reason to use two separate canvases? You won't have this problem if you had just one canvas.

It's a fun toy to play with! One thing I would improve: When drawing on the left half and moving to the right half without releasing the mouse, the drawing stops. I would expect the drawing to continue on the right canvas, while mirror

The anecdote about electrical education 100 years ago is great, I never thought about the similarities. I think electricity was the high-tech industry of that time, all the cool guys were building generators instead of apps. A lot of big pr
