Transcoding Latin 1 strings to UTF-8 strings at 12 GB/s using AVX-512
Though most strings online today follow the Unicode standard (e.g., using UTF-8), the Latin 1 standard is still in widespread inside some systems (such as browsers) as JavaScript strings are often stored as either Latin 1, UTF-8 or UTF-16 internally. Latin 1 captures the first 256 characters from the Unicode standard…

C and C++ prioritize performance over correctness
The original ANSI C standard, C89, introduced the concept of “undefined behavior,” which was used both to describe the effect of outright bugs like accessing memory in a freed object and also to capture the fact that existing implementations differed about handling certain aspects of the language, including use of…

We reduced the cost of building Mastodon at Twitter-scale by 100x
I’m going to cover a lot of ground in this post, so here’s the TLDR: We built a Twitter-scale Mastodon instance from scratch in only 10k lines of code. This is 100x less code than the ~1M lines Twi…

Ode to the M1
It is not often I am blown away by a piece of hardware. My Hall of Fame features the 1991 Super Nintendo, the 1995 3dfx1, and the 2010 Intel's Serie 520 SSD [1] . This past month my 2021 MacBook Pro M1 [2] joined the club.

What is gained and lost with 63-bit integers? (2014)
Almost every programming language uses 64-bit integers on typical modern Intel machines. OCaml uses a special 63-bit representation. How does it affect OCaml?

Squeeze the hell out of the system you have
When complexity leaps are on the table, there’s usually also an opportunity to squeeze some extra juice out of the system you have. By tweaking the workload, tuning performance, or supplement…

Graceful behavior at capacity
Suppose we’ve got a service. We’ll gloss over the details for now, but let’s stipulate that it accepts requests from the outside world, and takes some action in response. Maybe those requests are HTTP requests, or RPCs, or just incoming packets to be routed at the network layer. We can get more specific later. What…

Why libvirt supports only 14 PCIe hotplugged devices on x86-64
You might have used libvirt , a Linux daemon that provides an abstraction and management layer for virtualization software. This daemon allows you to submit an XML file containing a description of a VM, disk image or network. libvirt is then able to configure, start it and keep it running.
