This blog post is a slightly edited version of the live transcript of the talk I gave at RustFest 2019 in Barcelona on November 10th, 2019. As it's a transcript some parts of it are a bit repetitive or badly worded, but I hope the message behind the talk will be conveyed by this post anyway.
We rendered the top 1 million pages on the web, tracking every conceivable performance metric, logging every error, noting every requested URL. To our knowledge this produces the first dataset that connects performance, errors, and library use on the web. In this article we analyze what the data can tell us about…
Technical maxims that define Urbit's approach to engineering.
SIMD is a powerful performance technique, and is especially valuable in signal and image processing applications. I will be using it very extensively in my synthesizer, and also it’s increasingly used in xi-editor to optimize string comparisons and similar primitives.
Now they’ve gone an done it. An unidentified agency has spread a potent computer virus across all the world’s computers and deleted the binaries for every copy of every software development tool. Even the offline copies — it’s that potent.
You log in to a Linux server with a performance issue: what do you check in the first minute?
Google Cloud will now offer the ability to encrypt data in use, while it’s being processed in a Google data center
When we switch on a computer, it goes through a series of steps before it is able to load the operating system. In this post we will see how a typical x86 processor boots. This is a very complex an…
The time has come to replace file systems!
SentinelOne unifies AI-powered endpoint, cloud, identity, and data protection—enhanced by our Security Data Lake for seamless and efficient cybersecurity.
How TCP interacts with the characteristics of the Starlink service.
Ruby 3.2 YJIT has optimized the production workloads of Shopify and other companies. We encourage you to enable YJIT in production. Once Ruby 3.3 is released, it should make your application even faster.
Collectively, we have been thinking about sorting for longer than we have had computers. There is still an active literature 1 , 2 , 3 . We are taught that how the counts of comparisons and swaps vary with problem size is what matters: as problems get bigger, order dominates, and anything else is buried in the noise…
I needed to list all files in a directory, but ls , find , and os.listdir all hung. This is my story.
In 2010, Google engineers Daniel Peng & Frank Dabek published Large-scale Incremental Processing Using Distributed Transactions and Notifications , which described Percolator: a Google-internal database for random access transactional workloads where low latencies are not required. Percolator uses a global…
Join me as I test-drive the smallest ever Kubernetes distribution k3s. Find out how this runs on Raspberry Pi compared to kubeadm with Docker.
The Microsoft Azure Core Upstream team is excited to announce the Hyperlight project, an open-source Rust library you can use to create very small VMs for embedded functions. Learn more.

Since I work a lot with clustered VMs , I’ve ended up spending a lot of time trying to figure out how DNS lookups work. I applied ‘fixes’ to my problems from StackOverflow without really understanding why they work (or don’t work) for some time.
Go 1.21 adds a new port targeting the WASI preview 1 syscall API
Many recent Intel processors benefit from a new family of instructions called AVX-512. These instructions operate over wide registers (up to 512 bits) and follow the Single instruction, multiple data (SIMD) paradigm. These new AVX-512 instructions allow you to break some speed records, such as decoding base64 data at…
I recently gave a talk on the internals of multicore OCaml GC at Jane Street offices in NYC. The slides from the talk are available online . But I felt that the slides alone aren’t particularly edifying. This post is basically the slides from the talk annotated with notes.
