Twitter’s length limit is deceptive. At a glance, it suggests that writing tweets should be easy and quick. This is true for superficial tweets, but does not mean all tweets are written quickly and with little effort.
Twitter is actually a platform for concise writing, and writing concisely is harder than writing verbosely. There are certain tweets I spend a lot of time on and it’s shame to have them get lost in my feed. So I’m storing them here.Continue reading

Wrote a twitter thread about this:
Are you one of those people that believes their time is their most valuable resource?
I think this is wrong. Your time is valuable, but what’s most valuable is your decision making & creative energy.Continue reading
Most people thought I was crazy for doing this, but I spent the last few months of my gap year working as a short order cook at a family-owned fast-food restaurant. (More on this here.) I’m a programmer by trade, so I enjoyed thinking about the restaurant’s systems from a programmer’s point of view. Here’s some thoughts about two such systems.Continue reading
Most people thought I was crazy for doing this, but I spent the last few months of my gap year working as a short order cook at a family-owned fast-food restaurant. Here’s a short reflection on 2 things I learned from the experience as it pertains to my gap year. If you’re a programmer you’d probably be more interested in this post instead. Of course, I learned much more than this, but the rest is basic food service industry lessons that would be cringy to write about, so I’ll keep it to myself.Continue reading
This post details my adventures with the Linux virtual memory subsystem, and my discovery of a creative way to taunt the OOM (out of memory) killer by accumulating memory in the kernel, rather than in userspace.
Keep reading and you’ll learn:
- Internal details of the Linux kernel’s demand paging implementation
- How to exploit virtual memory to implement highly efficient sparse data structures
- What page tables are and how to calculate the memory overhead incurred by them
- A cute way to get killed by the OOM killer while appearing to consume very little memory (great for parties)
Congratulations! You just finished developing your first contribution to the Linux kernel, and are excited to submit it. The process for doing so is tricky, with many conventions that the community has developed over time, so here is what I learned after doing so for the first time. This is intended to be a succinct supplement to the official contribution documentation.Continue reading
