But again, this isn't intended for a general audience.

Anyone who might need this would already know what BPF is. And anyone who isn't familiar with the term BPF in this context wouldn't be the target audience for this.

It's also worth noting that BPF isn't ever referred to in it's non-acronym form. Literally no-one in the field calls this "Berkeley Packet Filter". Just like nobody calls PHP "PHP: Hypertext Processor" (or whatever backronym they've decided on this week), nor SQL as Structured Query Language. The name for this technically literally is just referred to as "BPF".

So while I agree with your point in general -- it's not really a fair complaint in this specific occurrence.

Well, it's posted on Hacker News which is a general audience including people working on electrical/signal/audio/radio-frequency systems among other things (not just low-level network code) where BPF has a different meaning, so I think disambiguation is appropriate.

And it's been explained on HN exactly what it is. So problem solved.

By the way, I noticed you didn't follow your own recommendation for the "RF" acronym in your comment. Nor "NASA" in your first reply. Perhaps you should check your own comments before you criticize others for doing the same.

Maybe you should also leave a comment in the Mullvad story (currently #1 on HN) that nobody has explained the VPN acronym there. Likewise for the threads where people reminisce about BASIC, of which there have been many lately. They're also only obvious if you already know the subject matter.

Thanks for the catch! Fixed :-)

Nitpick: eBPFs aren’t just for low level networking manipulations but also lots of other parts of the kernel. In fact the expanded version of the acronym is slightly confusing as it sort of implies being entirely to do with networking, which it isn’t.
