New article! A user *cough* @aras *cough* is reporting full system freezes while using Superluminal on Linux. What do you do? Cry? Well, we did a little bit.

But we also dove into the kernel...again, this time finding & fixing several issues in eBPF's spinlock implementation. Read all about it:

@rovarma @aras great story and writeup!

Also, it's good to hear Superluminal is coming to Linux. It might be useful should I one day decide to add bugs to my code. (:
