Rabin, co-recipient of the 1976 Turing Award and a giant in computer science, has died at 94. His foundational work on nondeterministic finite automata and the Miller-Rabin primality test fundamentally shaped the trajectory of computational complexity theory and modern public-key cryptography.</p> <h2 id="front-page-highlights">Front Page Highlights<a class="anchor" href="#front-page-highlights">#</a></h2> <p><strong><a href="https://amitlimaye1.substack.com/p/rewriting-every-syscall-in-a-linux">Rewriting Every Syscall in a Linux Binary at Load Time</a></strong> Instead of relying on <code>ptrace</code> or <code>seccomp</code>, this author built a hypervisor shim that replaces the <code>0F 05</code> syscall instruction with an <code>INT3</code> trap right at load time. It&rsquo;s a brilliantly unhinged but practical approach to sandboxing untrusted AI agent code with sub-microsecond overhead, gaining full execution control without a kernel module.</p>
