Deepseek_to_nowhere

My problem

I needed to find the CIDR from a range to block because of spam issues and I figured instead of calculating it myself I could ask Deepseek through Ollama no? It’s open-source after all and it’s supposed to be incredible so why not?

Mind you, I tried afterwards to compare with claude.ai and it answered within a second the right answer: 103.82.92.0/23

The settings

Model: deepseek-r1:14b
Ollama: 0.5.7
CPU: Ryzen 9 3900x
RAM: 64GB

Question

can you give me the subnet with the “/” notation for this range? 103.82.92.0 - 103.82.93.255. Just give the answer, nothing else

Traffikey

In the previous post, I’ve mentioned something called Traffikey that would help through my transition out of the Hashicorp products.

Since I’ve been using it for quite a while now and I’ve finally added some much needed features, I think it’s time to talk about it.

The use case

Put simply, etcd can be used by Traefik for it’s configuration of routers, services and middlewares the same way as Consul can be used. But since this would be all manual because there is nothing to “detect” those services, something would need to be automated to put the right keys at the right places in etcd.

The quest to find a replacement for Hashicorp products, part 1: Consul.

We can’t have nice things

Hashicorp recently changed their licensing for all their product. This new Business Source License isn’t open-source so that made me think of my usage of their product. With this change, I’ve decided it is time to move on from their product as it’s unsure where it’s going. Furthermore, some distributions like NixOS already marked the first version after the license change as non-free.

Got to start somewhere, no idea where this is going. This will be focused on technical things for sure. I’m not much of a writer to begin with.

Summary

I am a very hard working, resourceful and passionate person. I love to discover new technologies and improve my work methods in ways that can make my workflow faster and more efficient. I can adapt well to new problems and situations. I thrive under pressure while managing my time well to meet deadlines.

Give me a project and a deadline I will take it over the finish line. Over 15+ years I’ve been the person handed the ambiguous problem: designing infrastructure from a blank slate, writing the backend service it needed, migrating a system nobody wanted to touch, or building the tooling to keep the whole thing running. I don’t work inside one lane. I work on whatever the project actually needs to ship on time and hold up under load.
