SAS will stay with me for a long time
For too many reasons, this was my favorite conference by far
@TheSAScon, thank you for having me, I hope to see everyone again in future!

My favourite speaker at #TheSAS2026 has to be Mirko (@mirkhoff)! 🔥 Really enjoyed his talk, “Anarchy in the IR: When V8’s Compilers Disagree.” Definitely one of the highlights of the conference for me! 🙌
took me some time to finish this post:
"Breaking SSA Phi destruction in SYSyVM", could this be a #0day?! ඞ
