The Clojure Core team recently released a new Clojure library, tools.build , that is a culmination of thought around batteries-included build support for Clojure projects. I won’t go into detail around the history and contents of the library in this post because much of that is found elsewhere, including the…
"JVM Anatomy Quarks" is the on-going mini-post series, where every post is describing some elementary piece of knowledge about JVM. The name underlines the fact that the single post cannot be taken in isolation, and most pieces described here are going to readily interact with each other.
The primary admin account on an M1 Mac is its Owner, responsible for authorising the installation and use of second operating systems. Here’s what can go wrong with Ownership.

In our 54th reading group meeting, we were looking for an answer to an important question in the distributed systems community: “What about Raft?” We looked at the “ Paxos vs Raft: Have we reached consensus on distributed consensus? ” paper to try to find the answer. As always, we had an excellent presentation, this…

This post explains how Linux memory overcommit and OOM-killer behavior can turn a single runaway query into a full PostgreSQL crash, and why many managed cloud database services fail to disable overcommit the way self-hosted PostgreSQL recommends.
Failure in computer systems is inevitable. Adopting Erlang's philosophy of "Let it crash" at the many layers of abstractions in software can have a huge positive impact on resiliency.
During a recent RAID 5 recovery attempt, John made an interesting discovery inside the two failed disks. The plastic ramp that the heads park onto when idle had snapped in the same position on both drives. We don’t know if the heads got damaged first, and then broke the ramps during parking, or if the […]

In this article we’ll learn how to build shared libraries and install them properly on several platforms. For guidance, we’ll examine the goals and history of dynamic linking on UNIX-based operating systems.
Addendum : Many Hacker News commenters correctly point out that the right way to indicate to the compiler that a value does not change is const . This post is not about C best practices, but just about how one can easily get to the bottom of this kind of surprising behavior by looking at the compiler output. This…
A valid difference of opinion.
The job of a software engineer is not to produce code, but to solve problems; we just happen to solve most of those problems by producing code. Ultimately, producing code is hard, and we need help. That's why GitHub's Copilot is exciting, but it's far from ideal, and it's the tip of the iceberg of what's been done and…
