In a really broad sense, the history of observability tools over the past couple of decades have been about a pretty simple concept: how do we make terabytes of heterogeneous telemetry data comprehensible to human beings? We’ve seen different companies tackle this in different ways for technology like Ruby on Rails…
Binarly uncovers CVE-2025-3052: a Secure Boot bypass affecting most UEFI devices, enabling attackers to run unsigned code before OS load.
Learn how we tracked a performance bottleneck to a 15-year-old Git function and fixed it, leading to enhanced efficiency that supports more robust backup strategies and can reduce risk.
TigerBeetle is an Online Transactional Processing (OLTP) database built for double-entry accounting with a strong emphasis on safety and speed. It builds on the Viewstamped Replication (VR) consensus protocol to offer Strong Serializable consistency. Unlike general-purpose databases, TigerBeetle stores only accounts…
Introducing oniux: Kernel-level Tor isolation for any Linux app. This torsocks alternative uses namespaces to isolate Linux applications over the Tor network and eliminate data leaks.
We have some very fast AI-generated kernels in pure CUDA-C without using libraries and DSLs such as CUTLASS and Triton. They are performing close to or in some cases even beating the standard expert-optimized production kernels shipped in PyTorch. Some of our highlighted results:
Databricks offers a unified platform for data, analytics and AI. Build better AI with a data-centric approach. Simplify ETL, data warehousing, governance and AI on the Data + AI Platform.
Create DWARF debug information with the LIEF Extended DWARF editor and share reverse-engineered types and functions between Binary Ninja and Ghidra plugins.

Many Ruby applications allocate objects. What if we could make allocating objects six times faster? We can! Read on to learn more!
Today we’re very excited to announce the open-source release of the Windows Subsystem for Linux. This is the result of a multiyear effort to prepare for this, and a great closure to the first ever issue raised on the Microsoft/WSL repo:
A joyride through the dangers of lock-free programming.
In past years, the Rustls project has been happy to receive substantial investments from the ISRG. One of our goals has been to improve performance without compromising on safety. We last posted about our performance improvements in October of 2024, and we're back to talk about another round of improvements. What is…
The table below and notes which follow are a comparison of some of the different standard library implementations available for Linux, with a particular focus on the balance between feature-richness and bloat. I have tried to be fair and objective, but as I am the author of musl , that may have influenced my choice of…
In Lorena's latest instalment, learn about the foundations of Elixir's power and reliability with the Erlang Virtual Machine (BEAM).
Burstable VMs run on a fraction of CPU and burst to a higher level of CPU usage to support occasional usage spikes. To implement them, we leveraged Control Groups v2 (cgroups v2), a Linux kernel feature that helps manage resource usage. We thought our open-source implementation of burstable VMs might be interesting…
In JDK 25, Strings used as keys in immutable Maps can be much faster.
AWS’s Sergey Melnik, along with HN commenters matashii and Ants Aasma, have identified the cause of Long Fork in PostgreSQL clusters. As described a 2013 mailing list post , the order in which a PostgreSQL primary makes transactions visible is determined by an in-memory lock. Secondaries, however, make transactions…
It's waiting for Godot and eventually gives up.
ClickHouse learned to procrastinate strategically. Discover how lazy materialization skips unnecessary column reads to accelerate queries.
How we split Feldera into a thousand crates to use every core rustc can get, cutting compile times from 30 minutes to 2.
I did tell you not to do that.
Inside PgDog's wire protocol handling: parsing simple and extended messages, using pg_query for AST inspection, and routing queries via the Postgres hash partition function.
Previously, I said that TinyKVM runs regular Linux ELFs and I use this to test my programs on the terminal like a regular program before I load them in Varnish.
Colossus’s performance comes from its stateful protocol, which plays a pivotal role in the new Rapid Storage offering launched at Google Cloud Next '25.
Boost PostgreSQL full-text search speed by 50x with simple optimizations. Use VectorChord-BM25 to accelerate and better BM25 ranking in postgres.
