Experience Java like never before with Azul Prime. Turbocharge Java performance with a JVM that starts fast and stays fast, with less infrastructure.
A lot of people seem to think that distributed tracing isn't useful, or at least not without extreme effort that isn't worth it for companies smaller than FB. For example, here are a couple of public conversations that sound like a number of private conversations I've had. Sure, there's value somewhere, but it costs…
Memory management is the heart of operating systems; it is crucial for both programming and system administration. In the next few posts I'll cover memory with an eye towards practical aspects, but wi

There are many books available that deal with modernising legacy codebases. These books generally focus on how to go about understanding the legacy system, improving test coverage, introducing build automation, as well as strategies for refactoring or rearchitecting the codebase. However, Marianne Bellotti’s Kill It…
After failing to find good papers about distributed systems testing for many months, yesterday I asked a question in Twitter:
In this blog, we discuss continuous batching, a critical systems-level optimization that improves both throughput and latency under load for LLMs.
Minitest is a beautifully made test suite for writing tests to verify your expectations from your Ruby code base. Here's how to run tests in Minitest.
This paper is from SOSP'13. The Polyjuice paper, which we studied last week, built on the Silo codebase and commit protocol, which led me ...

This post might seem a little basic for folks who spend all day heads down in gdb or who do this stuff professionally, but I just wanted to share a quick intro to some tools that others may…
In 1978, Intel introduced the 8086 processor, a revolutionary chip that led to the modern x86 architecture. Unlike modern 64-bit processors,...

“Can I use Snappy Ubuntu Core on the Raspberry Pi?” is one of the most frequently asked questions we heard since launching Ubuntu Core for smart devices. Thanks to a very successful collaboration between the Raspberry Pi Foundation and Canonical, the company behind Ubuntu, we are pleased to announce that Snappy Ubuntu…
