Contributed by pitrh on Fri Jan 13 15:50:03 2017 (GMT) from the puffy the interface juggler dept. Martin Pieuchot has written another article chronicling the modernization of the network stack. Martin writes, I wrote a second article about the network MP thingy. The article talks about a new API built on top of a generic solution for a MP problem. The article, A story of if_get(9), is a followup to the part one article we featured earlier as Understanding the modernization of the OpenBSD network stack, part 1: ART single thread performances.

Get your name in the relayd book

Contributed by rueda on Sun Jan 8 04:02:42 2017 (GMT) from the bit-part-for-sale dept. Michael W Lucas is offering the chance to get your name in his forthcoming book on relayd and httpd: There’s a long tradition amongst science fiction writers of selling bit parts in books in exchange for charity donations. It’s called tuckerization. I see no reason why science fiction writers should have all the fun. I need a sample user for the forthcoming book on OpenBSD’s httpd and relayd. This user gets referred to in the user authentication sections as well as on having users manage web sites. They will also get randomly called out whenever it makes sense to me. That sample user could be you. All it would cost is a donation to the OpenBSD Foundation. See Michael's blog for details, and donate your way to fame(?) if you can!
