// Brand new home site launched!

Website you are viewing now superseded a simple landing page available here since 2009.

I'm going to publish here posts related to my interests and currently encountered issues.

New page is running on DokuWiki engine with my minor changes. Frontend platform is a tiny router with Marvell Kirkwood ARM CPU with Debian onboard, so some parts of dynamic content are served via Varnish + Nginx from more powerful backends. 100% of content is available via IPv6.

Some parts of former pages are still being moved.

Happy reading.
