Using FFmpeg to replace video frames
Machine learning algorithms for video processing typically work on frames (images) rather than video. In a typical use-case, FFmpeg can be used to extract images from video – in this example, a 50-frame sequence starting at 1:47: Omit the -vf…
FFmpeg lossless filtering
Preserving Data Running a simple FFmpeg filter command: … one might expect the output video to be the same as the input video. Note that both input and output videos use the same container format (file name extension), and the…

Thunderbird: Highlight row on focus
I use the keyboard a lot. For many years now, Thunderbird’s default theme (probably inherited from the desktop, which does the same thing on many dialogues) has had a little quirk that is slightly less conducive to keyboard use: It…
https and the browser conspiracy
While Google promotes HTTPS Everywhere, browsers have been working with a certifying authority oligopoly for many years promoting and enforcing an industry based on perception. https: The good and the bad The ‘s’ in https stands for ‘secure’ and indicates…
HTTP DDoS: “Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1)”
Our servers were attacked recently by a constant stream of HTTP POST requests. The requests were coming in from a large range of IP addresses, at a rate of about 5-10 per second, with random POST data. However, all the…
Shell escaping in Perl
Shell Escaping: There are several methods for escaping special characters in the Linux shell: Double quotes: Double-quoted strings require escaping of only a few characters. Example: >echo “Some String: &>|\”\$’\`\s\\” Some String: &>|”$’`\s\ This method is useful as long as…
