Twitter Web Client Inline Image Removal

If you're a heavy user of the Twitter web client like me then you'll find the new inline preview feature extremely intrusive as it breaks up the timeline too much. If I wanted to use facebook or linkedin then I'd be using facebook or linkedin. Having said that, cards in Twitter are great and the ability to preview media before jumping off site is really cool - but it should be my choice, not have everything foisted on my timeline.

That the mobile client allows for this with a setting is even more annoying.

So here's the fix. This only works in Chrome but I'm sure an enterprising person could do something similar for Safari and Firefox using the same CSS. Pull requests to update instructions for other browsers are of course very welcome.

Making your Cricket Australia live stream bigger.

If you signed up for Cricket Australia's digital streaming service this summer you'd be pretty disappointed with the very tiny size of the video stream. For those of us that can't get terrestrial TV for whatever reason and use digital services and paid good money for them this is a terrible decision.

Thankfully, with a bit of CSS-fu it's possible to get an almost full-screen video feed and get rid of all those rubbish ads to boot.

This is version one - mostly because I only did enough to be satisfied watching the first ODI. I'll keep this updated and refine it over the course of the summer.

 Basic ESP8266 MQTT example

 This sketch demonstrates the capabilities of the pubsub library in combination
 with the ESP8266 board/library.

 It connects to an MQTT server then:
  - publishes "hello world" to the topic "outTopic" every two seconds
  - subscribes to the topic "inTopic", printing out any messages
    it receives. NB - it assumes the received payloads are strings not binary
