If the constraints are that an object has to be of uniform density, convex, and not containing any voids, then you cannot choose where its centre of mass will be, other than by changing it shape.

This is categorically different from the Gömböc, because it doesn't have uniform density. Most of its mass is concentrated in the base plate.

Emacs Lisp vectors being fixed seems like an easily fixable problem. More functions can be defined to do useful things with vectors including mutations. If it is important to keep the existing type produced by make-vector immutable, a sep

Mathematics is dominated by chaos. Let's consider the real numbers. Most of them can't be written down. Most real-valued functions of just one variable cannot be written as a symbolic formula of that variable. Consider the n-body

Boiler plate that is primary (not generated from a concise generation) is counterproductive: instant tech debt. The way to to use AI is to get help writing that generation logic, not to just get it to crank out boilerplate. You're not

The easy fix is to have two bikes. You can take the time to work on the offline bike, not to mention get needed parts.

From even before Lisp was implemented for the first time, MacCarthy envisioned it as a langauge for symbolic processing: manipulating representations of formulas, exhibiting nesting. So yes, it was actually tree processing, using lists. Whe

I'm guessing that someone among the authors has some 486 hardware that boots and can do the build, and pass whatever tests they have.

If your configuration doesn't randomize the MAC, that doesn't guarantee you won't be involved in a conflict. It only guarantees that it will go more badly for you, since you will be waiting on the other device to change thei

On the contrary, I'm simply questioning the idea that we should all be switching to vectors and abandoning list structures, because of "modern" machines. Every other tech bro blowhard likes to repeat this. So, first of all, I

We are talking about hardware. How recent is this supposed "modern" time when it became faster to go to the next cell of an array rather than chase a pointer (in the best hand-written machine code to do either).

When some random tech person says "modern", the dividing line is usually the date when they started programming. Everything which was already available at that time is "modern", and none of it existed the year before tha

This has been an option in Android network settings forever: randomize your MAC. I think it's enabled by default now? It's a basic privacy feature; you can be fingerprinted by your device's MAC.
