What’s amazing, of course, is that Smith can steer a pointer with his brain well enough to text with his wife at home and answer our emails. Since he’d only been semi-famous for a few days, he told us, he didn’t want to opine too much on philosophical questions about the authenticity of his AI-assisted posts. “I don’t want to wade in over my head,” he said. “I leave it for experts to argue about that!” The eye tracker Smith previously used to type required low light and worked only indoors. “I

Even though I am a C++ programmer at heart, Go fascinates me for none of the reasons you think. Go has made several interesting design decisions: It has virtually no Undefined Behavior. It has very simple GC semantics that they’re mostly stuck with due to design decisions in the surface language. These things mean that despite Go having a GC, it’s possible to do manual memory management in pure Go and in cooperation with the GC (although without any help from the runtime package). To demonstra

I work on Dolt, the first SQL database with git-like version control, written entirely in Go. And as a rule, databases need to be fast. So we have lots of tests in our CI workflow to monitor performance regressions before they ever hit our main branch. Last month, a commit that was supposed to be a no-op refactor caused a 30% regression in sysbench's types_scan benchmark. Pictured: An example of what you don't want to see on your GitHub PR. Uncovering the root cause of this regression turned

Finding a crash while fuzzing is just the beginning of Vulnerability Research. After finding a crash, Exploit Development is often a long journey. Not every bug is exploitable, and my previous article (Case Study: Analyzing macOS IONVMeFamily Driver Denial of Service Issue) is great proof of that. Sometimes, I am sure that something can be exploited, but then I face a wall of mitigations implemented by the OS. During my recent fuzzing session, I discovered a bug that, after some readings, trial

The original version of this story appeared in Quanta Magazine. Sometime in the fall of 2021, Andrew Krapivin, an undergraduate at Rutgers University, encountered a paper that would change his life. At the time, Krapivin didn’t give it much thought. But two years later, when he finally set aside time to go through the paper (“just for fun,” as he put it), his efforts would lead to a rethinking of a widely used tool in computer science. The paper’s title, “Tiny Pointers,” referred to arrowlike

Sublinear Time Algorithms Sublinear time is a daunting goal since it allows one to read only a miniscule fraction of the input. There are problems for which deterministic exact sublinear time algorithms are known. However, for most natural problems the algorithm must use randomization and must give an answer which is in some sense approximate. There is a growing body of work aimed at finding sublinear time algorithms for various problems. Recent results have shown that there are classical optim
