  16 years ago today, after watching a presentation on YouTube titled "Write and Submit your first Linux Kernel Patch"[1] by @gregkh, I submitted my first patch[2] to the Linux kernel. 🙂 I didn't really have much idea of what I was doing, and after submitting a few more similar patches that same year (2010), I stopped. Years later, in 2017, I picked it up again, and haven't stopped since: https://embeddedor.com/blog/ 🐧⚔️🛡 [1] https://youtu.be/LLBrBBImJt4 [2] ht...

  I talked for more than two hours (135 mins to be precise) about upstream Linux kernel hardening at Okayama University this afternoon. 🐧👨🏽‍💻🎙 I just uploaded my slides here: https://embeddedor.com/blog/presentations/#Enhancing_spatial_safety_Better_array-bounds_checking_in_C_and_Linux_Okayama_University_%E2%80%93Guest_talk I really enjoyed the session. The students were amazing. They were well prepared and asked a lot of questions. 👏🏼👏🏼 #Linux #OpenSource #Education #Mentoring #Okayama #OkayamaUniv...

  While reviewing one of the patches sent to the linux-hardening list this afternoon, I spotted a bug I introduced in the same code two years ago (on March 5 2024, to be precise). Over nearly a decade contributing to the Linux kernel, I’ve discovered and fixed many years-old bugs, and it’s always a special feeling. This time is no different. Here to fix what I break! 🙌🏼 https://embeddedor.com/blog/2026/03/17/here-to-fix-what-i-break-fixing-a-2-year-old-bug-in-the-linux-kernel/ 🐧 #Linux #OpenSou...
