The Knowledge Graph Conference is currently happening in NYC and there's a bit of talk around KG assisting AI with various things like truth grounding (RAG) and Agentic development. Curious if anyone is seeing more discussions of Semantic Technologies in their orbit these days?

revisiting this question 9yrs later: https://news.ycombinator.com/item?id=7491925

Very curious how people are thinking about RDF/semantic technologies these days after the initial question was posed. With "Artificial Hallucinations" running rampant in the ChatGPT world, a call for more moderated/structured data may be a possible prescription which is where RDF/ST shines. While relational/no-sql continue to dominate our industry, I'm very surprised that a graphdb hasn't emerged to compete with the former given how incredibly flexible graphs are in our space.

Any good research going on with RDF/ST to call out here?

We are a large company and have many small systems with disparate key sets that we would like to standardized and would like to use UUIDs for the new global keyset. I have several questions regarding UUIDs if anyone can help with the answers.

1) Are there any issues co-mingling v4 & v5 UUIDs in a single system? We would use v5 to transition the legacy systems to UUID and v4 for generating anything outside the legacy systems (new systems).

2) Per https://tools.ietf.org/html/rfc4122, "A UUID is 128 bits long, and requires no central registration process.". This implies anyone in our ecosystem can generate a UUID and probably never collide. However, are there minimum restrictions on the machine that would generate these UUIDs? For instance, I would imagine a dependable clock (eg one that doesn't reset to 1/1/1970 ever time it restarts) is necessary, but do they all have to be in sync or is some measure of skewing acceptable? Anything else?

3) Is there a list of reliable (future proof) uuid implementations we can use to cover all the major languages or are the standard libraries sufficient for v4/v5 uuid gens? We have a mix of various flavors of *nix and windows in our ecosystem.

Thank you!

My wife is planning to do a bootcamp programming course. She's currently taking some prep course offered by the company and is progressing along doing various problems on a daily basis. This course is mostly independent studies where the instructor assigns problems with some lectures but you're expected to figure it most of it out on your own. You can ask questions and request help via a ticketing system but it's a little bulky to walk through. As I look through some of her solutions, I noticed she's a little deficient on some fundamentals (eg scoping, by value/reference concepts, etc.). They're learning programming using Javascript.

Obviously I can help her but I work during the day and she's taking some time off to focus exclusively on this pivot so I don't want her to sit around waiting on me.

Does anyone have any good resources (authors/books, bloggers, youtube instructors) that they like that has an easy to understand teaching style for beginners?

TIA

My wife is sorta in this middle management space and looking to sharpen and maintain her tech skills. Not necessarily programming but talk sufficiently in depth about current trends. Any recs on any periodicals/sites (subscription or free) that can keep her in the loop (have already recommending HN!)
