When I joined CloudFlare about 18 months ago, we had just started to build out our new Data Platform. At that point, the log processing and analytics pipeline built in the early days of the company had reached its limits.

We at Canonical have conducted a legal review, including discussion with the industry’s leading software freedom legal counsel, of the licenses that apply to the Linux kernel and to ZFS.And in doing so, we have concluded that we are acting within the r […]
I have gotten a significant amount of response on the Quake 2 extension mechanism. I do read everything that comes my way (I can't respond to all of it, though), and I have learned a few things from the mail.
In episode 379 of ATP both Marco Arment and John Siracusa described noticeable delays and stalls after upgrading to macOS 10.15.
After over two decades, players are now forbidden from flying a seaplane, all thanks to undefined code behavior.
If you remove the first word from the string "hello world" , what should the result be? This is the story of how we discovered that the answer could be your root password!

Pipes are ubiquitous in Unix --- but how fast can they go on Linux? In this post we'll iteratively improve a simple pipe-writing benchmark from 3.5GiB/s to 65GiB/s, guided by Linux `perf`.
I understand the classic UNIX Magic poster by Gary Overacre was distributed at past USENIX conferences, and I’ve known of it for years but now in confinement, I’ve decided I want one to hang in my ...
When it comes to infrastructure engineering, building a data center is probably closer to building a house than to deploying a Terraform stack.
Instructors of “Introduction to programming” courses know that students are willing to blame the failures of their programs on anything. Sorting routine discards half of the data? “That might be a Windows virus!” Binary search always fails? “The Java compiler is acting funny today!” More experienced programmers know…
Introduction My first encounter with docker goes back to early 2015. Docker was experimented with to find out whether it could benefit us. At the time it wasn’t possible to run a container [i…
Less than a month ago, I began investigating the Apple M1 GPU in hopes of developing a free and open-source driver. This week, I’ve reached a second milestone: drawing a triangle with my own open-source code. The vertex and fragment shaders are handwritten in machine code, and I interface with the hardware via the…
Dmitry.GR: Slowly booting full Linux on the intel 4004 for fun, art, and absolutely no profit
This is Part 1 of a series of posts. Part 2 is available here: Building a baseline JIT for Lua automatically It is well-known that writing a good VM for a dynamic language is never an easy job. High
The release of a small open-source operating system for deeply-embedded computer systems.
I have an affinity for performance optimization and making software as efficient as possible. Over the years, I've encountered specific instances and common patterns that make software or computers slow. In this post, I'll shine a spotlight on some of them.
PostgreSQL scalability on multicore and multisocket machines became a subject of optimization long time ago once such machines became widely used. This blog post shows brief history of vertical scalability improvements between versions 8.0 and 8.4. PostgreSQL 9.2 had very noticeable scalability improvement. Thanks to…
After a few weeks of investigating the Apple M1 GPU in January, I was able to draw a triangle with my own open source code . Although I began dissecting the instruction set, the shaders there were specified as machine code. A real graphics driver needs a compiler from high-level shading languages (GLSL or Metal) to a…
In this blog we'll discuss how we manage Cloudflare IP addresses used to retrieve the data from the Internet, how our egress network design has evolved, how we optimized it for best use of available IP space and introduce our soft-anycast technology
