Like most other technical people I know, I've been thinking about how AI is impacting my industry, and I found myself reminded of a different technology in a different field: auto belayers in rock climbing. 🧗

Still thinking about how how inspired I feel by @districtcon.bsky.social Year 1! I am enjoying still processing everything: engaging talks, a CTF, a badge challenge. Every room was filled with people with an insane amount of talent, skill, and experience.

🦀 Rust 1.92.0 was released yesterday! While reading the changelog, one thing that stood out to me was an update to the docs around build performance—not a main feature, but a useful improvement for anyone tuning compile times.

🔐📚 For cybersecurity professionals looking to do some technical reading: Saw this great @humblebundle.com deal for up to 18 books from @nostarchpress.bsky.social and supports @eff.org that includes essential reading for offensive and defensive techniques. www.humblebundle.com/books/hackin...

💡 Trivia: What language was used to write the first Rust compiler? Today's Rust compiler is self-hosting (written in Rust, compiles itself using an existing compiler). But this raises a question: How was the very first Rust compiler created when there was no Rust compiler to build it? #RustLang

Today I switched my deployment from staging to production using GitHub Environments. Same workflow, but GitHub Actions automatically loaded all the prod secrets and configs. No script changes needed—it just worked exactly as designed. Love to see it! #GitHubActions #DevOps

That moment your GitHub Actions workflow launches and AWS happens to be releasing the new 5.x.x version of your action and you catch the very moment they are re-creating the high-level v5 tag 👀

AWS Lambda now officially supports Rust! 🦀 This is huge news from pre:Invent 2025, bringing Rust's performance, memory efficiency, and safety to serverless functions. What AWS re:Invent (Dec 1-5, Las Vegas) announcements are you most excited about? #AWS #Rust #Serverless

Cloudflare's biggest outage since 2019 came down to an `.unwrap()` call that "should never fail" - until it did. Key lesson: "This can never happen" usually means "hasn't happened yet." Always implement proper error handling in prod! Kudos to Cloudflare for the transparent postmortem 🦀

Had a great time at MoCo Code & Coffee yesterday. Loved hearing what everyone’s building and swapping ideas. Already looking forward to the next one ☕💻 If you’re in MoCo and looking for a friendly group to code, chat, and caffeinate with, check out the meetup link: www.meetup.com/mocode-coffee/

Any D.C.-area folks planning on DistrictCon in January? GA tickets open tomorrow (Nov 16) at noon. Early Bird sold out in 30 𝘴𝘦𝘤𝘰𝘯𝘥𝘴, so set those alarms. ⏰ 🎟️ here: www.districtcon.org/tickets

Always love when textbook authors let their creativity (and sneaky humor) shine through in the code examples. From O'Reilly's Programming Rust, 2nd Edition #RustLang #Rust #RustProgramming #OReilly #Learning

🔧 #GitHubActions Tip: Watch Out for System PATH Resets! When using self-hosted runners, GitHub Actions resets the system PATH when executing jobs. This can break your workflow if you've pre-installed dependencies on your runner. 1/4

Have you logged into GitHub today? They've updated the color scheme to be festive. Happy Halloween!

Did you experience any issues accessing web applications yesterday? It felt like déjà vu with so much of the internet affected by the AWS outage early last week, but this time it was Microsoft's Azure cloud service. Link to the official Preliminary Report in thread 🧵⬇️

1/5 How I'm Actually Using AI in My Development Workflow 🤖 I recently heard someone describe AI as "spicy autocomplete," and after chuckling, I realized it's a perfect description of how I benefit from AI daily.

Today's bash regex puzzle: Can you spot the problem? 🤔 Goal: Match alphanumeric tokens with dots, hyphens, and underscores. Examples: abc123.test-token_example my-awesome.token_123 user_token-2.0 First attempt: $token =~ [A-Za-z0-9.\-_]+ (answers in thread...)
