Encrypted Media Extensions

Now that Season 3 of Rick and Morty has been completely aired, it’s time to start watching. I’m not a big fan of waiting a week between episodes, especially when the episodes are only 20 minutes long.

As of last night, all but the final episode of the season was available on Netflix and Ana has a subscription for this. This is the first time I’ve seen Netflix being used, so I didn’t know that the W3C Recommendedation “Encrypted Media Extensions” that upset the EFF enough for them to resign from the W3C has actually been in use by Netflix since April 2013 (growing platform support over time, not supporting all platforms immediately).

Hugo Syntax Highlighting

I’ve been tidying up my Hugo theme in an effort to make it reusable by others. In doing so, I’ve learnt about a lot of Hugo features that I didn’t know existed, like shortcodes. I remembered this concept from long ago in Wordpress and I had even written a plugin that took advantage of them.

I’ve been manually writing out HTML for figures, instead of using the figure shortcode. I haven’t started to fix these up yet, but I have made some changes for syntax highlighting.

MAC Catching

As we walk around with mobile phones in our pockets, there are multiple radios each with identifiers that can be captured and recorded just through their normal operation. Bluetooth and Wifi devices have MAC addresses and can advertise their presence to other devices merely by sending traffic, or by probing for devices to connect to if they’re not connected.

I found a simple tool, probemon that allows for anyone with a wifi card to track who is at which location at any given time. You could deploy a few of these with Raspberry Pis or even go even cheaper with a number of ESP8266.
