How to write a rootkit without really trying
We open-sourced a fault injection tool, KRF, that uses kernel-space syscall interception. You can use it today to find faulty assumptions (and resultant bugs) in your programs. Check it out! This post covers intercepting system calls from within the Linux kernel, via a plain old kernel module. We’ll go through a quick…

Streaming Video and Audio with Low Delay
Data sent over the Internet will traverse a large number of smaller links. The combination of these links forms a path from the sender to the receiver. Sometimes data is lost when it traverses this path. For video and audio streams such losses can lead to playback glitches if not corrected.

Improving compression with a preset DEFLATE dictionary
A few years ago Google made a proposal for a new HTTP compression method, called SDCH (SanDwiCH). The idea behind the method is to create a dictionary of long strings that appear throughout many pages of the same domain (or popular search results).

VP9 encoding/decoding performance vs. HEVC/H.264
A while ago, I posted about ffvp9, FFmpeg's native decoder for the VP9 video codec, which significantly outperforms Google's decoder (part of libvpx). We also talked about encoding performance (quality, mainly), and showed VP9 significantly outperformed H.264, although it was much slower. The elephant-in-the-room…
