I'm also there:

notes.vrypan.net is where share links and notes.
I'm @vrypan on Twitter. There's also @vrypan_ for tweets in greek.
I also write on Medium every now and then, but most posts are also posted to my blog.
And every now and then, I may write some code: my GitHub page.
My keybase profile: keybase.io/vrypan

Active Projects:

bucket3 — a simple, blog aware, static site generator written in python.
listnr — a webmentions endpoint (more about it here).
VSRE — Very Short Reply Expected (email netiquette)

Old/Inactive/Retired Projects:

Longaccess — Long-term data archiving. Retired in 2016.
BigStash — Stash away stuff you won’t need in the near future. Retired in 2016 (this was an experimental service by Longaccess).
tlbx.io — "tools to analyse, monitor and automate your Dropbox better." Retired in 2016.
jekyll-post-via-web — post to a GitHub hosted Jekyll blog, using this simple, self-hosted bookmarklet. The code is there, but I haven't done any updates for very long.
URLBorg — a URL shortener using AppEngine. This was my first try to write production code for GAE. Retired in 2009.
monitor — the Greek glogs aggregator. Started in 2005, monitor.vrypan.net played a central role in the early Greek blogoshpere. Retired in 2007.
lilina — an open source feed aggregator in PHP that required no DB backend.. Started in 2004, this aggregator was as simple as it could get (no DB), but was also one of the first to experiment with what would later be called "web mashups" and "web 2.0". Ryan McCue took ove r the project in 2006.
g-metrics.com — measure the occurance in google results of a keyword or set of keywords defined by you accross time. I started this in 2004, shortly after Google anounced a public API for Search. It was also mentioned in O'Reilly: Google Hacks.

A twitter mention or direct message is probably the best way to contact me. But if you really, really have to contact me by email, please, read vsre.info before emailing feedback@vrypan.net
