bpftrace is a new open source tracer for Linux for analyzing production performance problems and troubleshooting software. For example, iostat(1), or a monitoring agent, may tell you your average disk latency, but not the distribution of this latency. software Kernel software-based events.

In the MySQL open source ecosystem, we have only two consolidated ways to perform sharding — Vitess and ProxySQL. Let’s see the write operations with 24 and 64 threads: We get a gain of ~33% just using sharding, while for latency, we do not have a cost. Why ProxySQL?

Created by Alastair Robertson , bpftrace is an open source high-level tracing front-end that lets you analyze systems in custom ways. eBPF was created by Alexei Starovoitov while at PLUMgrid (he's now at Facebook) as a generic in-kernel virtual machine, with software defined networks as the primary use case. eBPF does more.

Apple Corporate is at fault, not Open Source engineers or the line managers who support them. The open, royalty-free codec AV1 has been delivered instead. For heavily latency-sensitive use-cases like WebXR, this is a critical component in delivering a good experience. So is speedy resolution and agreement. CSS color().

Suz Hinton's talks on WebUSB show the through-line: as the web gets more capable, whole classes of software suddenly benefit from frictionless deployment, increased safety, better privacy, and more meaningful user controls. Together, they make software better. Other use-cases weren't addressable with early 2000's tech.

If both AVIF and WebP are not viable options, consider evaluating MozJPEG (optimize JPEG images), OxiPNG (non-photographic images), or JPEG 2000 (lossy or lossless photographic images). The AV1 image file format (AVIF) is an open-source image format for storing still and animated images. Jump to table of contents ?.
