In this article, learn about file path formats on Windows systems, such as traditional DOS paths, DOS device paths, and universal naming convention (UNC) paths.

ZeroNet is a decentralized web-like network of peer-to-peer users, created by Tamas Kocsis in 2015, programming for the network was based in Budapest, Hungary; is built in Python; and is fully open source. Instead of having an IP address, sites are identified by a public key. The private key allows the owner of a site to sign and publish changes, which propagate through the network. Sites can be accessed through an ordinary web browser when using the ZeroNet application, which acts as a local webhost for such pages. In addition to using bitcoin cryptography, ZeroNet uses trackers from the BitTorrent network to negotiate connections between peers. ZeroNet is not anonymous by default, but it supports routing traffic through the Tor network.

The latest notions from the developments on human-AI partnerships (yes also DeepSeek), and thoughts triggered by lessons from the global south and blockchain reflections.

The last weeks I've been focusing a lot on the data and information models in architecture. Organizations have so much data flowing around that it's hard to effectively map it all out. That's a shame because there are some very valuable learnings to be had from that data.

DeepSeek, a company associated with High-Flyer, an $8 billion Chinese hedge fund, changed the AI narrative when it claimed OpenAI-like capabilities for a mere $6 million. The company challenged con…

Most people know that robots no longer sound like tinny trash cans. They sound like Siri, Alexa, and Gemini. They sound like the voices in labyrinthine customer support phone trees. And even those robot voices are being made obsolete by new AI-generated voices that can mimic every vocal nuance and tic of human speech, down to specific regional accents. And with just a few seconds of audio, AI can now clone someone’s specific voice. This technology will replace humans in many areas. Automated customer support will save money by cutting staffing at ...

Researchers at the University of Waterloo's Cheriton School of Computer Science in Canada found that modifying just 30 lines of code in the Linux kernel could cut data center energy consumption by 30% to 45%.

Entering 2025, I decided to spend some time exploring the topic of agents. I started reading Anthropic’s Building effective agents, followed by Chip Huyen’s AI Engineering. I kicked off a major workstream at work on using agents, and I also decided to do a personal experiment of sorts. This is a general commentary on building that project. What I wanted to build was a simple chat interface where I could write prompts, select models, and have the model use tools as appropriate. My side goal was to build this using Cursor and generally avoid writing code directly as much as possible, but I found that generally slower than writing code in emacs while relying on 4o-mini to provide working examples to pull from.

Since IPv6 is gaining momentum, and is generally operating alongside other protocols, it has become important to define the operating modes that may exist in any IPv6 environment. This allows for consistent communication and understanding of a fundamental part of operating a production network. Most of this hard work has been done by the IETF, and 99% of those definitions as can be referenced by engineers and architects when creating designs, proposals, and documentation, can be found in one really well crafted RFC.
