A short meander through some of the more obscure miscellany within Unicode. Languages hang around far longer than there are native speakers, and symbols get reused and repurposed (🍆). Here are some of the delightfully old-fashioned symbols hidden in your thoroughly modern smartphone.

Update for 2019! Twitter have changed how they compress images. Some of the techniques in this blog post may be out of date. Let's talk image compression!

Maximum quality for 6 channel audio. opusenc --bitrate 4096 out.flac out.opus Create an .mkv Add to an MKV with all the chapter information. mkvmerge -o test.mkv --chapters…

I'm lucky enough to get invited to speak at a variety of conferences around the world. After accepting a speaking invitation, and checking I'm not on an all-male line-up, I usually make one of the following requests to the organisers. Thanks for inviting me. Can you let me know if the venue is wheelchair accessible? So excited to be there. What are the crèche facilities going to be? Looking forward to speaking. Will you be providing a sign-language interpreter? Can't wait to see you. Please …
