I like to tinker and build. Growing up, it was Erector Sets, Lincoln Logs, and Legos. Now that I'm older I sometimes play with old muscle cars or tune firearms for target shooting. Overwhelmingly, I've always tinkered with code.

In days gone by, people would unambiguously refer to this tinkering as "hacking", and that's where the name of this blog comes from. In it, I explore different ideas about systems through my opinionated perspective. I am not one to play a game of research-as-marketing, and I'm definitely not a talking head blogging about the work of PhD students that I consider to be dogs pulling my sled. I am in the trenches, building systems that are (usually intricately) related to ideas I discuss.

These days, I'm a Ph.D. student in Computer Science at Cornell, specializing in distributed systems. I also serve as a distributed systems consultant.

    Non-Volatile Memory (NVRAM) is rapidly becoming the focus for the next generation of data-backed applications. In this post we will look at some of the pitfalls that come from using NVRAM as a direct replacement for DRAM and propose some (hypothetical) solutions going forward.

    Proof-of-Concept DB (pocdb) is a demonstration of how one could use Paxos to implement a strongly consistent key-value store. The code base is approximately 1,000 lines of code, and is intended to act as a teaching example that can be easily digested quickly.

    Consus is a new transactional key-value store that provides strong guarantees across data centers. Consus is a spiritual successor to HyperDex, another transactional key-value store. This post describes why I have switched my focus from working on HyperDex to working on Consus, what that means for HyperDex, and why I believe Consus to be the path forward.

    Consus is a geo-replicated transactional key-value store. This post introduces Consus, describes its open source release, and discusses the merits of releasing the code in advance of the publication. Finally, the post references other key-value stores related to Consus
