One of the highlights of Open Source Summit Europe 2025 was the deep and insightful technical talk on Container Performance Isolation delivered by Jonathan Perry, founder and CEO of Unvariance and a maintainer of the OpenTelemetry eBPF network collector:

I highly recommend this talk to anyone interested in the topic.
I would also like to thank Jonathan for patiently answering my technical questions after the session.

On the final day of the conference, James De Vile from RISC-V International delivered a short but very valuable talk about streamlining barriers to entry for new RISC-V developers. He outlined key steps for getting started, including obtaining membership at RISC-V International.
Short. Clear. Concise.
Congrats, James!

From vision to reality: RISC-V in action.

On the final day of the conference, 🗡⚔️🛡Yuning Liang, CEO of several companies including DeepComputing and a true RISC-V believer, delivered a great talk on his company’s RISC-V products and shared his strong personal support for the ecosystem.

I want to thank Ying for staying true to RISC-V values, for the inspiring talk, and for his patience and willingness to answer questions ranging from beginner to expert level.

Another great meeting — this time with Kaiwan N Billimoria, author of the excellent book Linux Kernel Programming, 2nd Edition:

As a reminder, Kaustubh Manglurkar from Packt had asked me to review this book a while ago. You can find my review in one of my earlier posts, or in the Editorial Review section on Amazon.

Highly recommended!

Hello everyone,

As you might remember, I previously reviewed a best-in-class book by Chris Simmonds and Frank Vasquez:
"Mastering Embedded Linux Development":

This was at the request of Kaustubh Manglurkar from Packt.

Yesterday, I had the opportunity to participate in an expert session with one of the authors, Chris Simmonds.

I want to thank Chris for the wise and insightful conversation.

Back in January 2024, I came across this post in a Google search: 🔗 https://lnkd.in/dzstA-fs That discovery set me on a path where I applied, was accepted, and successfully graduated from the Linux Kernel Mentorship Program (LKMP) – Linux Kernel Bug Fixing Spring Unpaid 2024. This week, I had the honor of presenting the results of my half-year journey at Open Source Summit Europe 2025, Amsterdam. I would like to warmly thank everyone who supported me along the way: Shuah Khan – mentor Javier Carrasco Cruz – co-mentor Julia Lawall – guest mentor Your support and inspiration were invaluable throughout this journey. A special thank you to Monika Masciangelo, who patiently answered my endless questions before the conference and helped me present successfully. I would also like to thank the The Linux Foundation, who made my presentation possible by inviting me to speak at the conference. And finally, thanks to all the attendees who received my presentation so warmly. #LinuxKernel #OpenSource #LKMP #OpenSourceSummitEurope25 #LinuxFoundation #Mentorship

I would like to warmly thank Greg Kroah-Hartman for providing us with such insightful answers to our questions during the Expert Session.

Excited to share that I’ll be presenting at the LFX Mentorship Showcase during the Open Source Summit Europe 2025 in Amsterdam!

On Tuesday, Aug 26 (17:00–18:30 CEST) at RAI Amsterdam, I’ll talk about my journey in the Linux Kernel Bug Fixing Spring 2024 Mentorship Program.
I warmly invite everyone attending the Summit to join this session and connect!

My friend @Needlesscomplexity has posted two articles about RISC-V assembly language techniques to his substack:
https://needlesscomplexity.substack.com/p/efficient-risc-v-range-checking
https://needlesscomplexity.substack.com/p/efficient-sign-extension-on-risc
And a library of useful integer operations:

I did a lot of assembly language programming back when dinosaurs still roamed the earth, and there are still some valid use cases even today. I firmly believe that having a grasp of assembly language also helps one write better HLL code.
