I'm Juho, a systems programmer currently living in Zürich. My blog covers whatever I'm currently interested in. In the past that has included posts about my Perl Golf exploits, stories about compiler and language runtime hacks (mostly for SBCL), and network programming.
For the past few years I've been an engineering lead at Teclo Networks, where we make TCP accelerator network appliances (originally aimed at optimizing TCP in mobile networks, but these days also for enterprise deployments). It's likely that a fairly large proportion of future posts will be related to things I've learned about networking and network programming during that time.
If you want to get in touch, my contact information is available.
