Random tech topics I find interesting to share
I’ve been using Home Assistant for a while now. It is not ideal, but it does work and you can pretty much make it do anything you need for your home automation. My HA runs on a Raspberry Pi4, and I use a CC2531 ZigBee USB dongle to communicate with the Ikea and Philips lights,…
If you’re googling this and are eager to have a chroot running on your x86 Synology box, please scroll down.These instructions worked for me on my DS416play. Should work for you too.
Pi-hole is the best way to get rid of all the ads on all of your devices on your local network. You set it up as your DNS server and it blackholes all the requests for ad servers. No more ads on your network!
For a while now we’ve had the .NET Core, which is a cross-platform (Windows, Linux, MacOS) framework that allows you to write stuff in the C# for example and afterwards run it wherever you like. Say what you will, but once you’ve tried Visual Studio it is a bit hard (at least for me) to…
To my surprise I found that there’s no usable unrar command on my RaspberryPi. I run Raspbian on it and it so happens that I wanted to unpack a rather large rar file. The unrar-free package is not good enough for some archives, so that is not an option. So how to get a working…
I got quite the surprise today while opening a file for editing using vim. fx@teikapi2:~ sudo vim /etc/hosts Segmentation fault Say what? Vim, segfaulting? Okay. There was an automatic apt-get upgrade on this machine today, so that is the explanation. Still quite weird and most definitely not expected. Quick backtrace under gdb showed: #0 _dl_lookup_symbol_x…
So I wanted to play a bit with Systemtap on Debian Jessie. I installed it: sudo apt-get install systemtap Afterwards I wanted to run a quick one-liner: fx@cloudhawk:~$ stap -L ‘nd_syscall.*’ Checking “/lib/modules/3.16.0-4-amd64/build/.config” failed with error: No such file or directory Tip: /usr/share/doc/systemtap/README.Debian should help you get started. It failed, but hey, at least it…
As much as I enjoy hardcore command line stuff, it is nice to have some eye candy there as well. Like htop, for example. However I have recently discovered vtop. Not sure about the practicality of it but it sure looks nice (albeit at the expense of some additional cpu cycles): If you have node…
Yes, it works. How cool is that? The hardest part is to set up your environment and even that is easy. Kudos to MS. What you’ll need: a linux machine, golang, packer, Azure plugin for packer, nodejs, Azure cli tools and an Azure subscription. I’ll start with a clean Ubuntu 14.04 machine. Let’s start by…
For I while now I wanted to complete the Linux Foundation Certified Sysadmin exam and this week I did it. Yay! If you’re a linux admin then this will not present too much difficulty to pass it. The LF certification page explains what domains and competencies will be tested and this can be used to…
