Brief note on LuaWrapper and unexpected crashes in destructor & destructor ordering
PowerDNS products rely heavily on Lua, and we mostly use the most excellent LuaWrapper  to seamlessly share data and code between Lua and C++. LuaWrapper is such a fundamental part of our products that we took over maintenance of LuaWrapper when the genius ...

This week, one of my heroes died a highly untimely death. (...) In this post I want to honour and perpetuate his work on delivering the real, rational, story of how we use energy and how we could (not) generate it sustainably. Because sadly, this is going to be far harder than optimistic articles and politicians would have us believe. Please help spread the word!

How to do fast canonical ordering of domain names
A small post to document an arcane subject: how to quickly do a comparison of DNS names in canonical order. First, to recap, what is DNS canonical ordering? It is case insensitive, but 8 bit, based on the labels that make up the DNS name in reverse order. S...

Some notes on sendmsg()
This post is mostly so other people can saves themselves the two days of pain PowerDNS just went through. When sending or receiving datagrams with metadata, POSIX offers us sendmsg() and recvmsg(). These are complicated calls, but they can do quite magical ...

Think Uber, AirBNB, Slack and Snapchat are innovative? Think again! Learn from the people that got us to Mars in this meandering post on invention that ends up with a book review.

Fun graph from a dnsdist user today! Blue in this graph represents "really fast answers". User added 1 PowerDNS server to the pool which already contained two non-PowerDNS servers. But why did things improve SO much? Turns out the default dnsdist load balancing policy ('leastOutstanding') quickly decided to send ALL traffic to PowerDNS (since this gave a smaller queue), and nothing to the two legacy servers :-)

(I’d like to thank Dirk Peeters who taught me most things RFP and Remco van Mook for commenting on and improving this post.) As I find myself in RFP-land again, I found myself pondering how my previous startups spent tremendous amounts of time working on th...

Design of DelayPipe, a small class to let you execute millions of things in the near future
When developing, quite frequently we run into the situation where we want to delay an action a little bit, perhaps for half a second. If your software is not highly concurrent, this is as easy as a call to one of the more granular sleep() calls now availabl...

I have never felt more welcome in a restaurant in The Netherlands! The owners care deeply that you have a great time & great food. And it works! It is like a small piece of Italy in The Hague. We'll be back a lot!
