Welcome to Fixpoint: the blog of Jacob Welsh and a journey of convergence toward roots underway since 2019.

The sidebar navigation links provide a number of cross-sectional views of the items herein, or you can subscribe to the global articles and comments RSS feeds. There are also some historical bits still up on my older hand-coded site.

I'm an applied cryptographer and key management consultant, with skills in system administration (principally Linux/UNIX), networks, software development, and teaching. I earned the degree of Bachelor of Science in Computer Science from the University of Virginia in 2012. I worked variously as an intern, part-time and full-time engineer for Sine Nomine Associates from 2007-2013, and as an independent contractor 2013-2016. I co-founded JWRD Computing and have served as its Chief Technical Officer since 2016. I've been playing with Bitcoin since 2012, and became active in The Most Serene Republic in 2019 through submission to the Young Hands Club ("jfw" in its chat logs). I held good standing in the Web of Trust as of the Republic's 2020 closure. These days I'm also involved in testing for Eulora2.

The best way to reach me about subjects on this blog is, of course, the comment box on the relevant article. Presently, all comments passing my CUPTCHA(i) and not otherwise from known-spammy corners of the 'net are published.

For chat, stop by #jwrd on our Internet Relay Chat network; I'll usually respond within a day. This is a public forum with logs updated in real-time under the logs category.

Failing that, you can try email: pwhtp4@welshcomputing.com, replacing the garbage spamtrap before the @ sign with "fixpoint". Platforms that I once graced with my presence but which will NOT work to reach me and certainly do not speak for me include Facebook, LinkedIn, GitHub and GMail.

My GPG key is here and reproduced in full below.

I've also certified some subordinate keys for specific uses:

  3. Dear KevinNop,

    I don't suppose these would be the same 2367896 public figures & politicians as exactly sitted elsewhere? And with the same drop address even? You don't think they'd catch on?

    Anyways, in the vanishingly unlikely event that any "dangerous community guys" find zheir ways over here, I can but point to the proximate source:

    although it's unlikely the good folks at CDN77 have any more to do with this than I.

    Incidentally, rh3torica.com isn't even my domain name although it has a record pointing here; its owner had this to say on the subject:

  6. @Isabellajah: Fished this out of spam to point out that finding and using my blog is indeed one of the better ways to start something serious with me. Your link is broken, though.
