The QOI File Format Specification
Last month I announced a toy project called QOI — the Quite OK Image Format . It losslessly compresses RGB and RGBA images to a similar size of PNG, while offering a 20x-50x speedup in compression and 3x-4x speedup in decompression.

Kafka vs. Redpanda performance – do the claims add up?
Apache Kafka has been the most popular open source event streaming system for many years and it continues to grow in popularity. Within the wider ecosystem there are other open source and source available competitors to Kafka such as Apache Pulsar, NATS Streaming, Redis Streams, RabbitMQ and more re

A Tale of Query Optimization
Last December, I got an interesting bug report from the VWO support team. It seemed like the loading time of a particular analytics report was ridiculously slow for a big Enterprise customer. Since I am part of the Data platform, a flag was immediately raised and I got involved in debugging the issue.

Unpacking Elixir: Resilience
The nine nines. 99.9999999% of uptime. Whether the AXD301 actually deserves to be held up as a system of nine nines seems debatable. I am not particularly interested in that debate. Erlang has a strong record for reliability and a design intended to help you as a developer and operator achieve your nines. Maybe just…

Why Intel Added Cache Partitioning
Typical server utilization is between 10% and 50%. Google has demonstrated 90% utilization without impacting latency SLAs . Xkcd estimated that Google owns 2 million machines . If you estimate an amortized total cost of $4k per machine per year , that's $8 billion per year. With numbers like that, even small…

Switch Lowering in GCC
We have seen in a previous post that switch statements are more complex than they seem. The compiler is able to implement them as a decision tree (even though maybe it shouldn't). Is that everything it can do?

Modern CPUs have a backstage cast
If you take someone with intermediate knowledge of computing in the right areas, and ask them how an x86 machine boots, they'll probably start telling you about how the CPU first comes up in real mode and starts executing code from the 8086 reset vector of FFFF:FFF0. This understanding of how an x86 machine boots has…

Caddy compatibility for zeroserve: 3x throughput and 70% lower latency
zeroserve is a high-performance HTTPS server that runs eBPF scripts in userspace ( intro ). Now it's got a Caddy-compat mode - when provided a Caddyfile, zeroserve JIT-compiles it to eBPF and then to native x86_64/ARM64 machine code, and runs it in an io_uring event loop.
