Pinned post

Hello, I'm Florian. I have been on here since 2018.

I work as a system and network engineer for the RIPE NCC. I'm a Domain Name System (DNS) and Border Gateway Protocol (BGP) expert and I'm responsible for running one of the 13 root name servers. In short, I'm one of the people keeping the Internet running. :flan_royal:

In my spare time I hack on OpenBSD and found my niche with privilege separated network daemons. :flan_hacker:

I like hiking and bicycle touring. We live with four people (two species felis catus, two species homo sapiens) in a house with a garden in the Netherlands. :flan_cat:

I identify as socialist but you'll find very little political commentary from me here.

A wise person once said: "Computers were a mistake." I can't agree more.

Since srand(time(NULL)) is good enough for the NSA, it ought to be good enough for everyone. We can stop with the getentropy() / arc4random() nonsense...

Blessed are the pessimists for they have made [offsite] backups.

We do have bugs but our bugs were hand-crafted by humans.

This (*waves at everything*) turns more and more into a Culture novel. The only problem is, it's the Affront who are designing and training the ship minds...

Every plan needs at least 4 people:
1. The person with the plan.
2. The person who's responsible.
3. A patsy
4. The person doing the work.

@mwl you mentioned the other day that you'd been introduced to the LOTR movies. I just came across this open tab, HTH: mastodon.social/@Richard_Littl

Oh: " I don't know what I'm doing. I'm rawdogging life..."

@danlew Actual conversation with the people who installed our dishwasher last year:

Them: "nice machine you got there"
Me: "it was the only one without wifi"
Them: "oh, so you're in IT?"
