Elm @ DublinJS February 2016

I gave a short Elm talk to the DublinJS meetup, extolling the virtues of functional programming.

To be honest, I was expecting a very hostile audience but it was super friendly (yay!) and I got really excellent questions. There should be video of that, so hopefully if you can scrub past me you can get to the questions :)

You can find my slides and examples on Github. You can view the slides on SlideShare.

Most importantly, I really recommend watching Evan's talk, it's fun and really gives you the feel for Elm's philosophy, and is much better than my talk :)

Oops, I Elm Tutorial'd Again

So I got "tricked" into running another Elm tutorial.

This time I tried to focus more on Signals and the graphics, and less on HTML.

Overall I think it went better, but everyone (including me) ran out of steam after the food arrived, so I should have stopped it there. Future lesson: Elm basics + Signals in tutorial 1, Models, updates and maybe Effects in tutorial 2. I think I can crack this Elm teaching thing soon.

Thanks to Functional Kats for putting up with, I mean, hosting me :)

Shonky Network Setup of the Day

So, here I am helping another GameCraft, this time I'm hoping to write a simple game using my shiny new Flotilla on my Raspberry Pis.

First problem: connecting to the network for stuff. The GameCraft is graciously being hosted by DIT in their excellent new Grangegorman campus. They have also given us access to the Wifi. The problem is it's 801.x so it's awkward to configure using WPA supplicant on a Pi.

Second problem: To get around this I want to share the wifi from my Macbook over an ethernet cable to a wifi router I brought for just such an occasion. The problem here is OS X won't share an 801.x connection.

Convoluted solution: Connect to the wifi from my Mac, then turn on my VPN connection (with send all traffic turned on), then share that connection to my Wifi router, which my Pis can connect to. Simples.

Bonus: For some reason the Irish VPN endpoint isn't working so I'm routing via the UK.

Ok, I could just simply connect the Pis to my router and my laptop to that, but then I'd lose the ability to download all the code I forgot to download in advance :)
