If you run a home lab, this one's for you! Omer from @devopstoolbox just dropped a video on managing home lab:
✅ Real domain, not .local nonsense
✅ Valid TLS with caddy
✅ Headscale for remote access
✅ DNSimple for DNS that stays out of your way

📡 The recent “GemStuffer” spam wave used RubyGems like a public dead drop: fetch data, wrap it in a gem, push it to the registry, retrieve it later with standard tooling. A very odd abuse of package infrastructure. socket.dev/blog/gemstuffer

Really enjoyed this conversation with @weppos. Some of my own early web development work involved DNS, so this one was especially interesting to me. We went nearly two hours… because I wanted to get into the weeds.
The On Rails podcast is back with a new season! In this first episode, host @robbyrussell chats with Simone Carletti (@weppos), CTO of @dnsimple, where Rails has powered the main application and API since they launched in 2010. They chat about what it takes to keep a long-lived codebase healthy with a lean team of around 15 engineers.
🎙️ Listen to the full episode here: podcast.rubyonrails.org/2462…

🚨 New Investigation: Attackers are hunting the maintainers behind Lodash, Fastify, buffer, Pino, mocha, Express, and #Nodejs core, because compromising one of them means write access to packages downloaded billions of times a week.

The fact that so many developers are fine with paying a huge monthly bill for AI models but won't donate a fraction of that money to open-source projects that make their software work is a great example of how monetization of OSS is a culture problem.

Did you know that frankenphp.dev/ is actually *the* software I dreamed of having since I was writing PHP at 11 years old?
IT FINALLY EXISTS.
Thank you @dunglas for your amazing work on it!

✨ We're feeling nostalgic as we gear up for the very last #RailsConf ! Today flashback "2016" when our CTO @weppos took the stage at RailsConf Kansas city.

Thank you, RailsConf, for the memories, the inspiration, and the friendships🚀❤

There is an increase of account takeovers due to insiders at telco firms simply giving control to people paying them. Do a check on systems where this would permit a compromise.
We can confirm that the account @SECGov was compromised and we have completed a preliminary investigation. Based on our investigation, the compromise was not due to any breach of X’s systems, but rather due to an unidentified individual obtaining control over a phone number associated with the @SECGov account through a third party. We can also confirm that the account did not have two-factor authentication enabled at the time the account was compromised. We encourage all users to enable this extra layer of security. More information and tips on how to keep your account secure can be found in our Help Center: help.x.com/en/safety-and-sec…
