The licence is not a hurdle. HF licencing in Canada is simple. You get the transmitter certified ($500) and then you rent the spectrum licence. Since there is actually not much demand for HF spectrum it's quite cheap. If you plan

It seems to be a vibe coded joke that implements a database in the worst way possible. For example, it appears to store post data in the timestamps and permission bits of the file system.

Practically? Quite a few codebases from *nix systems rely on the case sensitivity. To do a successful git clone you need a file system that handles both Makefile and makefile, or whatever. I ran into it more than once back in the day when

Very cool. I've been working on something similar. My cutoff date is 1994 as Usenet changes substantially in nature then. May I ask how you collected the data? Usenet is not fully archived anywhere. No one has a complete set. I am

For that type of structured data (logs and such), a custom dictionary can be extremely effective. Zstd among others support generating a custom dictionary. You just run zstd --train over the data first, and then feed that in when you run

Effective natural language processing of sign languages. Current LLMs are almost completely incapable. And it's a steep hill to climb. No text corpus. Must be learned from video. I do not believe current LLM approaches are capable

I'm reminded that chips like the Intel 8080 and Motorola 6800 were not intended to be general-purpose computers, and were originally designed mostly to be embedded controllers and as building blocks for "real" computers like

I consider most deep learning and statistical learning systems to be AI. But I also consider traditional symbolic AI to be AI. You only underline my original point: no one can define AI.

All of the major hearing aid manufacturers incorporate DNNs or transformers into their chipsets. The manufacturers advertise it as "AI" and that's probably a fair description. It's a kind of filter, implemented with neu

I find it fascinating how self-aware the Mespotamians were of their own literary culture and history. Later rulers would do early forms of archaeology and dig up the ruins of earlier kings. The Library of Ashurbanipal has sign lists (prot
