Household Slack

Hi all, Been a while since my last post. It has also been a while since I did something interesting that was worhty of a blogpost. Bought a house last year, brought along with it a lot of stuff that needed to be done, a lot of to-do lists, a lot of sharing ideas for wall colors back and forth between me and my significant other. We used to use Facebook Messenger to talk to each other when not physically in the same room, but we don't like Mark anymore.

Don't want to terminate your SSL connections on the haproxy server? Just do it like this! SSL terminations happen on the respective backend servers.

Reverse engineering list of used games

In Belgium we have this retailer, which sells games. And then buys them back again, and tries to sell them again. They have a slow, bulky website that allows you to search through the used games, based upon your platform of choice, and your preferred store. But wouldn't it be cool if we could scrape this data, and see when games where being brought in, and when they disappear again?

Packaging python into rpms (like a boss)

What do you do when you need to package an rpm on an Ubuntu box? You use Vagrant and FPM ofcourse! Tools needed: vagrant virtualbox fpm a git repo with python waiting to be packaged into rpms Vagrantfile: # -*- mode: ruby -*- # vi: set ft=ruby : Vagrant.configure("2") do |config| config.vm.box = "centos/6" config.vm.network "private_network", ip: "192.168.33.10" config.vm.provision "shell", inline: <<-SHELL # Clean up everything yum clean all # Install Software Collections yum install centos-release-scl -y # Install ruby193 + needed dependencies for fpm and some tooling yum install ruby193 ruby193-ruby-devel python-setuptools git -y yum groupinstall 'Development tools' -y # Set ruby193 to be default one echo "source /opt/rh/ruby193/enable" | sudo tee -a /etc/profile.

Poor man ILO | IDRAC

When buying an expensive server you get some kind of way for remote access when the server has made a booboo. I wanted the same thing: to be able to keep connecting to my Raspberry Pi's when I made a booboo with the network config. This is my first iteration: just being able to see the console. Next iteration will hopefully add some way to reboot/reset the pi remotely. Parts needed:

MQ-135 CO2 Sensor part 2

Couple of updates since my latest post: I added a new Wifi hotspot, called it ThaissaPatrickInternetOfThings, for all of my IOT gagdetery, since the girlfriend was complaining about the internet being slow because of all the devices connected to it. Added a logic level converter since a collegue (you know who you are!) pointed out that the sensor operates at 5v and the Wemos at 3.3V Took some pictures: !
