Trail of Bits recently completed a security assessment of Kubernetes, including its interaction with Docker. Felix Wilhelm’s recent tweet of a Proof of Concept (PoC) “container escape” sparked our interest, since we performed similar research and were curious how this PoC could impact Kubernetes. Quick and dirty way…

This is part two in my series of articles about bytecode interpreters, based on a small stack virtual machine which I have nicknamed PM…
QUIC, the new internet transport protocol set to replace TCP, was comprehensively built by tech industry leaders over nearly seven years. Go behind the scenes to see how QUIC evolved from a lofty experiment to a standard set to modernize the internet.
When considering the panel to discuss concurrency, you’d be pushed to find a higher calibre than Sir Tony Hoare, Joe Armstrong, and Carl Hewitt.
Have you ever wondered how well PostgreSQL performs on a Raspberry Pi 3B ? Oh. You haven't? Oh well, I asked myself that question and put it to the test. This post covers how I used pgbench to answer this question and the results of what I found.
It seems like it was just six months ago that we announced Fedora 29, and here we are again. Today, we announce our next operating system release. Even though it went so quickly, a lot has happened in the last half year, and you’ll see the results in Fedora 30. If you’re impatient, go to […]
Parallel Commits are an atomic commit protocol in CockroachDB. The feature promises to halve the latency of distributed transactions by performing all consensus round trips required to commit a transaction concurrently.
Advancing the state of the art of HTTP/2 to deliver a faster user experience. See why it matters and how much of a differenc
TL;DR: x86_64 decoding is hard, and the number and variety of implementations available for it makes it uniquely suited to differential fuzzing. We’re open sourcing mishegos, a differential fuzzer for instruction decoders. You can use it to discover discrepancies in your own decoders and analysis tools! In the…
CockroachDB uses RocksDB for its storage engine because of RocksDB's rich feature set, which is necessary for a complex product like a distributed SQL database.
In this deep-dive, we identified and worked through sporadic latency issues with services running on Kubernetes in our environment.

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…
Today, Red Hat has introduced a new Linux development model into the CentOS community: CentOS Stream, a developer-forward, faster-moving distribution that helps community members, partners and others take full advantage of open innovation.
Martin Sebor looks at C string handling functions used to copy and concatenate strings and examines ways to improve their efficiency.
Get a closer look at how we investigated errors originating from scheduled jobs, and how we stumbled upon "the tyranny of the clock."
