I'm not in the mood today

I wasn't vocal about it, but in the past few weeks, the support of eBPF has significantly improved in all iximiuz Labs playgrounds. I have tweaked the current 5.10 kernel several times, and support for the 6.1 kernel is coming soon as well. Example 👉 labs.iximiuz.com/tutorials/intr…

I'm periodically being reminded that there is no such thing as overcommunication. For folks who missed my update from a couple of months ago, it's now possible to publish your content on iximiuz Labs. Your ideas, our engine, everyone's enjoyment labs.iximiuz.com/for-creators

DAYS SINCE ETCD BACKUPS SAVED OUR ASS IN PRODUCTION: 0 If you manage your Kubernetes clusters and think you won’t lose your etcd, you’re almost certainly wrong. It takes years for the disaster to happen and you’ll be glad you have invested in building a backup/restore system.

5.3K out of 12K of the backend code rewritten, force pushed 17 times, and almost done (tm)! 😅

I think it would be a lot of fun to stream hacking things, learning new tech, vuln research, etc...

Multi-network playgrounds come to iximiuz Labs 🎉 This concludes the backend redesign for persistent playgrounds. The only missing part is the UI tweaks in the playground wizard to make the new capabilities available: - Custom sets of machines - Rootfs as a remote OCI image -

Free Linux, Networking, Containers, and Kubernetes playgrounds 🔽 50 (and counting) remote playgrounds. Always up to date, ideal for learning, experimentation, and ad hoc hacking, including running rogue AI agents 🙈 Check out the full collection at labs.iximiuz.com/playgrounds

This tweet should have been a case study, but I don't really have time for it. The first university course hosted on iximiuz Labs has just successfully finished. The theory and the practice both leveraged the content publishing and the playground capabilities of the platform 🚀

Teaching courses or conducting trainings on Linux, DevOps, or the like? Give iximiuz Labs a try labs.iximiuz.com/for-trainers 😉

I'm so behind schedule, but also the scope has grown so much that I don't feel too bad about the extra time spent. Here is what we've got. It's pretty much how I envisioned the ideal playground creation process from day 1 but never had enough time to actually build it until now🚀

Wrote a blog: containerd v2.1, nerdctl v2.1, and Lima v1.1 medium.com/nttlabs/contai…

Guess what is becoming even more relevant with agents, loads of AI-generated code, and other LLM slop? Reliable and safe infrastructure, in general, and containers in particular. The only way to herd agents is to understand what they're doing, so IMO practicing fundamentals

Releasing something hot today 🤞 - New playground constructor - "Bring your own VM rootfs" - Multi-network playgrounds - Multi-drive virtual machines - Linux kernel 6.1 (experimental)

Updated labctl to support Playgrounds 2.0. Now you can launch custom remote playgrounds from the command line with Kubernetes-style manifests. Next step: labctl-mcp 🙈 github.com/iximiuz/labctl…

Networking 101: How Traffic Routing Works 🔽 Did you know that computers can only talk with their neighbors (members of the same subnet)? But how can we then send packets across the Internet? That's where the routing comes into play. Learn more: labs.iximiuz.com/challenges/net…

Hey folks! 👋 To recognize a major milestone, the Playgrounds 2.0 release, I'm running an unprecedented event. For the next few days, you can get the iximiuz Labs Premium membership with a (very) sizeable discount. Don't miss it! And here is what the Playgrounds 2.0 is about 👇
