It’s winter. Here’s some hot IT links to warm you up (What I find interesting in tech, January, 2026 edition)

I haven’t posted on tech in awhile, which I think is a shame, because I like to see these posts myself, if no one else does. Especially I like to come across them years later and think: oh yeah, I was working on that then. Or think: I forgot about that…I need to take that up again.

So here are dozens of good links on IT that I have found interesting over the last year while I’ve been developing software that uses much of the technology you see highlighted below.

As always, almost all of these links are self explanatory. The ones that aren’t…well…few if anyone but me reads these posts anyway. Just treat it like a collection of potentially good resources that I found worthy of sharing.

AWS: I was doing some work on pushing containers into AWS (which I wrote about, here) so I found these useful
Okta/Authentication: before I pushed the containers into AWS, I had to integrate them into Okta. So I did a ton of research on Okta. Here’s some of the links I found useful:
API Dev: my code has a FastAPI interface, so I also had a few issues on that front I had to figure out first:
Milvus: likewise my code interacts with Milvus, which took a moment to master. Ha! Master! I have barely scratched the surface: 
Langchain: Langchain is at the core of my application, so I have been doing lots of studying on this software:
RAG: RAG is another essential part of my application, specifically agentic RAG. Hence these links:
Other good stuff: I’d be remiss if I didn’t keep these links and share them….some of them are especially good.

Finally here’s the obituary for Lou Gerstner. IBM and my place in it was greatly and positively affected by him. I wonder if there would have even been an IBM anymore if Lou did not come along. May he rest in peace. More on his impact on IBM, here.
