Suppose that I give you a long list of strings (e.g., “A”, “A6”, “AAAA”, “AFSDB”, “APL”, “CAA”, “CDS”, “CDNSKEY”, “CERT”, “CH”, “CNAME”, “CS”, “CSYNC”, “DHC”, etc.). I give you a pointer inside a much larger string and I ask you whether you are pointing at…

Happy to share our FUZZING'23 paper on analyzing fuzz blockers: https://t.co/CzQR5iIFzW. This work is led by my PhD student @WentaoGao5 in collaboration w/ @Alan32Liu, @halbecaf, @tobycmurray, and @bipr. Can't wait to e-meet #fuzzing lovers in the workshop…

CPU design is hard. You can tell because there aren’t a lot of companies doing it. AMD and Intel are your only choices in the PC scene. In the Android ecosystem, ARM Ltd’s cores dominate. Qualcomm, MediaTek, Samsung and other SoC makers put chips together…

The strategy for winning is simple: do good work and tell the world about it. In that order! This implies some level of stealth as you are doing the good work. If you plan to lose weight, don’t announce it… lose the weight and then do the reveal. Early feedback…

Suppose that I give you a short string of digits, containing possibly spaces or other characters (e.g., "20141103 012910"). We would like to pack the digits into an integer (e.g., 0x20141103012910) so that the lexicographical order over the string matches…

The C++11 standard introduced used-defined string suffixes. It also added regular expressions to the C++ language as a standard feature. I wanted to have fun and see whether we could combine these features. Regular expressions are useful to check whether…

GPUs started out as devices meant purely for graphics rendering, but their highly parallel nature made them attractive for certain compute tasks too. As the GPU compute scene grew over the past couple decades, Nvidia made massive investments to capture the…

In software, it is common to represent time as a time-stamp string. It is usually specified by a time format string. Some standards use the format%Y%m%d%H%M%S meaning that we print the year, the month, the day, the hours, the minutes and the seconds. The…
