Where'd I get the nick "rewbycraft"?

Short version: No, I didn't get it because of MineCraft. See the long version for the reason why.

Long version: A long time ago I first started to get into programming with a program called GameMaker. I was 7 years old at the time (I think, it has been a *long* time). At the time I needed a name to sign my little games and experiments with (sadly, the files have gotten lost over time and the nick fell into disuse). 7 year old me thought he was being clever by taking my name and combining it with the word "craft" which, when translated to Dutch, means roughly the same as "maker". Some time ago a friend mentioned MineCraft to me and I decided to check it out (first by watching YouTube videos and later on trying a cracked version of the game (I did end up buying it)) and I decided to bring back the nick for it. The nick has since stuck around.

We've got to go back!

TechCavern is a community of people from all over the world. While not the most Safe For Work community, the people there and the things we talk about are rather interesting.

As one of TechCavern's few admins, I look after one of our Minecraft servers and the channel as a whole.


DN42 is a big dynamic VPN, which employs Internet technologies (BGP, whois database, DNS, etc). Participants connect to each other using network tunnels (GRE, OpenVPN, Tinc, IPsec) and exchange routes thanks to the Border Gateway Protocol. Network addresses are assigned in the range and private AS numbers are used (see registry) as well as IPv6 addresses from the ULA-Range (fd00::/8)

I operate a fairly large network in the project, the ASIX network.


While the name is not exactly short, it is accurate. The purpose of this program is to watch for new clients on a JACK server and automatically connect it to other clients following a set of rules defined in the configuration file.

These are the places where you can come into contact with me (IRC is your best bet):
