Hacker News with Generative AI: Code

How Big Is OpenVMS? (vmssoftware.com)
This question was asked during my Boot Camp presentation last fall in Boston, and over the past 35 years dozens of times people have asked, how big is VMS? That translates into "how many lines of code are in VMS"? I thought it was time to at least make a stab at pursuing some insight into the answer. I wrote some command procedures to count the number of source lines in .B32, .B64, .C, .MAR, .M64, and .S files.

Implementing LLaMA3 in 100 Lines of Pure Jax (saurabhalone.com)
In this post, we'll implement llama3 from scratch using pure jax in just 100 lines of code. Why jax? Because I think it has good aesthetics. Also jax looks like a NumPy wrapper but it has some cool features like xla; a linear algebra accelerator, jit, vmap, pmap etc., which makes your training go brr brr.

Five coding hats (dubroy.com)
Early in my career, I was convinced there was “good code” and “bad code”. That you could look at something and — without knowing anything about the context — pass judgement on it.

In C some things aren't what they seem – The Craft of Coding (wordpress.com)
In C it is possible to make up things that don’t exist. For example this can lead to operators being created when they don’t exist, at least in the eyes of the programmer. Take the “–>” operator. This operator doesn’t exist, but can function as if it does. Here is an example program:

What does f(x) mean in C++? (biowpn.github.io)
It is universally agreed that C++ is a complex language. One reason is that its syntax is highly overloaded, meaning that the same code could mean many different things. Let’s do a simple mental exersice by considering the following code:
