I would like to keep a local portage tree on it — it currently mounts the tree over NFS due to ... http://smorgasbord.gavagai.nl/2012/01/file-slack-space-calculator/ Legoland. Je kunt er van alles worden. Behalve als je vrouw bent. Dan ben je dat gewoon, "vrouw". "Hee, vrouw!" zegt de beroepsbevolking dan op straat tegen je. Of: "Zeg meisje daar! Word jij ook vrouw als je groot bent? Zal wel hé?" http://smorgasbord.gavagai.nl/2011/11/vrouwelijke-arbeidsparticipatie-in-legoland/ Stel: je beheert zo'n miljardenpensioenfonds, en je belegt dat in vastgoed — woningen in de vrije verhuur, flatjes op Kijkduin. Dan is wel zo aardig als daar daadwerkelijk huurders in komen. Jij wil verhuren, huurders willen huren, vraag en aanbod zoeken elkaar op. Alhoewel... Als verhuurder wil je er waarschijnlijk Nette ... http://smorgasbord.gavagai.nl/2011/10/de-markt/ Quite a while ago, I ranted about Facebook, their email "validation", and their rather eccentric take on quality assurance. Things have changed at Facebook — you can now sign up using a sub-addressed email account. Friend suggestions But there may have been more to it than improper validation. One of the many ... http://smorgasbord.gavagai.nl/2011/08/facebook-and-email-sub-addressing-but-of-course/ For a little while I've been running a DIY dynamic DNS service. My peers think it's convenient and pretty sweet, so in this post I'll set things straight — a full disclosure on the mess that it really is ;-) What is a dynamic DNS service? Since the dial-up days of yore ... http://smorgasbord.gavagai.nl/2011/08/homemade-dynamic-dns-service/ While planning my upcoming "Except Hungary"1 cycling trip I did some research on land mines, since I might find myself passing through areas mined during the Yugoslav wars of the 90's.

It just so happens that, for a certain project, I need the ad-hocishness of SQLite *and* multiprocess write concurrency. It appears ... http://smorgasbord.gavagai.nl/2011/02/postgresql-quickie-server/ Argh, soft switches So what's a soft power switch anyway? Let's start with the converse: a regular light switch, say, of the tumbler type. You switch it in the 'on' position and voila, light. There's a power cut and off it goes. But the switch maintains 'state', so when the mains ... http://smorgasbord.gavagai.nl/2010/12/soldering-your-way-around-soft-power-switches/ A while ago I received a question from a reader. He was having some trouble with a pretty interesting setup. As I was rather intrigued I spent some time to figure it out — it's solved, but I'm not 100% sure on the theory.
