Interesting: Crafting Endless AS Paths in BGP

Vincent Bernat documented a quirk I hope you’ll never see outside of a CCIE lab: combining BGP confederations with AS-override can generate endless AS paths.

I agree entirely with his conclusions (avoid both features). However, I still think that replacing an AS within the confederation part of an AS path (which should belong to a single well-managed AS) is not exactly the most brilliant idea I’ve seen.

For Meta Platforms, An Open AI Policy Is The Best Policy

For Mark Zuckerberg, the decision by Meta Platforms – and way back when it was still known as Facebook – to open much of its technology – including server and storage designs, datacenter designs, and most recently its Llama AI large language models – came about because the company often found itself trailing competitors when it came to deploying advanced technologies. …

Avoiding downtime: modern alternatives to outdated certificate pinning practices

In today’s world, technology is quickly evolving and some practices that were once considered the gold standard are quickly becoming outdated. At Cloudflare, we stay close to industry changes to ensure that we can provide the best solutions to our customers. One practice that we’re continuing to see in use that no longer serves its original purpose is certificate pinning. In this post, we’ll dive into certificate pinning, the consequences of using it in today’s Public Key Infrastructure (PKI) world, and alternatives to pinning that offer the same level of security without the management overhead.  

PKI exists to help issue and manage TLS certificates, which are vital to keeping the Internet secure – they ensure that users access the correct applications or servers and that data between two parties stays encrypted. The mis-issuance of a certificate can pose great risk. For example, if a malicious party is able to issue a TLS certificate for your bank’s website, then they can potentially impersonate your bank and intercept that traffic to get access to your bank account. To prevent a mis-issued certificate from intercepting traffic, the server can give a certificate to the client and say “only trust connections if Continue reading

Using Vale to Improve my Writing

Back in March of this year, I talked about how I started using markdownlint-cli to perform linting against the Markdown source files that are used by Hugo to generate this site. At the same time, I also started exploring the use of similar tools to check (or lint, if you will) my writing itself. In this post, I’ll share with you how I started using Vale to perform some checks against my writing.

More details on my use of markdownlint-cli are available here for reference. markdownlint-cli checks for the structure and formatting of Markdown files, but it doesn’t do any “higher level” checks regarding the writing itself. For that, I needed to add a second tool, and I opted to use Vale, an open source tool specifically aimed at “linting your prose.” Among other things, what I liked about Vale was that it offers integration with graphical editors like Visual Studio Code (what I use when I’m on macOS) and Sublime Text (what I use when I’m on Linux), but it also can be run directly from the command-line. And, if you are so inclined, there’s a GitHub Action for Vale, too. Nice!
