Some time passed since I last wrote about OBS. In 2014, I started using OBS as a streaming solution for an event in Sao Paulo. I had quite some time to convince the co-organizers that streaming to an app and YouTube at the same time is a good idea, and Read more…
Raspbian is based on Debian. Upgrading it to the latest version is done the same way as upgrading a normal Debian distribution. To not make this my shortest blog ever, I’ll show how I upgrade one of my Raspberry Pi. The upgrade to release N is performed by starting the Read more…
After setting up a DHCP server on a Raspberry Pi running Linux I get working leases for my clients. However, these are not static. It can happen that my smartphone gets a new IP address the next it connects: 192.168.0.161 instead of 192.168.0.160. For some clients I want to make Read more…

Recently I got some new hardware that I will use to run some useful software. To use the software from anywhere, I’ll need to have remote access. As I cannot do DMZ or port forwarding with my new internet provider, I decided to connect my home server using VPN to Read more…
A 5xx error code is returned by a web server when something went wrong: The server was not able to process the request. For a reverse proxy, a common 5xx error message is 503, meaning that the backend server is not reachable. In the technical architecture of my blog site, the Read more…
2016 is history. As I have done in last year, I will use the start of a new year to look back at my private blog to see if my experiment is still on track. 2016 was the first year my blog was up and running for a full year. Read more…
After installing GateOne on my Raspberry Pi 2 Debian system, I can log on to SSH via HTTP and browser. But only from my internal network, as the external accessible port is blocked by Apache. To add GateOne from outside, I either can disable Apache (no, won`t do it) or Read more…
