Latest news

I recently attended PerlCon, where I delivered a keynote speech on Perl 6 concurrency as well as an update on my work on Perl 6 performance. The slides for both can be found on my talks page. The Swiss Perl Workshop dates unfortunately didn't work for me this year.

I recently developed Log::Timeline, a module that helps visualize and understand what is happening in parallel and concurrent Perl 6 applications. There's a visualizer for it in Comma IDE; I've been finding it helpful in my own work, and hope others will too.

I'm a little behind with my page about trying to travel on all of the Czech railways; it covers all of my 2018 trips, but not yet 2019.

Elsewhere online...

I blog about my work on Perl 6. Or at least, I used to; I'm still doing the work, but got less good at writing about it.

I've got some amount of code on my GitHub account - mostly Perl 6 modules.

I'm @jnthnwrthngtn on Twitter, and even bother to tweet stuff occasionally.

See my consulting profile at Edument, the company I have worked for since 2010. I am co-founder of Edument Central Europe, based in Prague.

My Hobbies

Travel and Trains

I'm a keen traveller, having visited over 40 countires so far. I've managed to stand on every continent except Antarctica - which remains a dream! I am especially fond of train journeys; some of the most memorable were in Switzerland, China (especially the railway to Tibet), Japan, Russia (the classic Vladivostok to Moscow route), and New Zealand.

Photography

I find photography an enjoyable and creative experience, especially while travelling. I'm not into lugging around heavy equipment to get the best possible technical image; it's the composition of images that interests me more. These days I am using a Sony RX-100, which I'm plenty happy with. My photos adorn the front of my slide decks, and I make a photo calendar each year for family also.

Cooking

A decade ago I really couldn't imagine cookery becoming one of my hobbies. These days, I find it a pleasant way to unwind after a day at the keyboard, or a nice way to while away some hours on a weekend. Indian cuisine is by far my favorite thing to cook - and, of course, to eat! A handful of spices and a frying pan have given way to a couple of shelves of spices, a karahi, and a tawa.
