The videos of the presentations held at the Embedded Linux Conference 2010 have been recently made public on Free Electrons. I was particularly interested in one speech: Custom Hardware Modeling for FPGAs and Embedded Linux Platforms with QEMU (PDF slides and OGV video). John Williams (PetaLogix) illustrates the work they have been doing on reducing […]

A few tips to speed up boot for your Linux box: 1. You need a tool to measure performance objectively: bootchart is very useful to track the lifetime of the processes, disk I/O and CPU load during boot. It needs no configuration whatsoever: you install it (for example using “apt-get install bootchart” in Debian-based systems) […]

When the visibility of these patterns is raised, so that more developers know and understand them, better quality code […]
