Like lots of people I’ve dabbled in step and fitness tracking for a while now, and one of my favourite tools to help me make sense of things is Exist. Exist is a (non-free) web service which pulls togther various tracking apps, like step trackers, mood, smart scales, runkeeper, last.fm and weather data and then shows you everything on a cool dashboard. While I use the dashboard as the main feature, Exist goes a step further and actually tries to correlate your different sources of data in order to help you gain some knowledge from all your tracking.

Update: after about a year and a half I realised I had a typo in the hardware name! It’s ESP8266, not ESP2866. I’ve updated the post to reflect this! You can find the corrected post at: https://hackerific.net/2016/02/21/an-iot-thermometer-with-esp8266-and-mqtt/

I bought a couple of cheap NodeMCU dev boards from aliexpress and decided to write turn them into simple remote thermometers. This post chronicles what I did, and how I did it. I won’t describe my MQTT setup too much, as I think that’s another post, and like most IoT manufacturers I’ve totally ignored security here! I’m hoping that a couple of these devices will let me make an intelligent wireless thermostat system with multiple room thermometers.

Mac Dev Tools

I’ve written in the past about various bits of Mac software, but not recently. This posts details some of the apps I use most days to make software development easier. Background I do most of my development work in virtual machines running CentOS 7. CentOS is a free distribution, based on RHEL, and both of these are commonly used and rock-solid Linux distributions. Because I tend to work on VMs, I tend to use an SSH client to connect to them, and so do most of my work remotely, on the command line.

This is a quick post on the static site generator Hugo, which I’m now using to power hackerific.net, with a little bit tacked on the end about how quick and easy it was to start using Let’s Encrypt to get working SSL certificates for this site, for free! These are both excellent projects, definitely work a look. Hugo I’ve been a fan of static site generators since I first read about Jekyll, but I was never completely happy with my setup.
