For fear of turning this blog into a Chinese Restaurant Process I've spawned a new category, called tips. This category is the closest to my original vision for a PhD-blog, where I would write down useful things as I learned them. It turns out that's not very sustainable (PhD involves …

I gave an 'Introduction to PGP'-type talk/tutorial at CryptoHarlem last night. PGP can be a little confusing and it gets a lot of criticism for being unusable, so I tried to focus on the higher-level aspects, like how it works and why you want that. I fear it ended …

I'm working on an embedding procedure for placing things into vector spaces. Things which might not normally live in a vector space (although in a sense we all live in a Lorentzian manifold). The basic idea is to take a model, present a bunch of examples of these objects relating …

In my previous post about getting Pond running on Yosemite, I ran into an issue with the GUI. The CLI interface seems to be fully-functional and pleasant enough for me, but GUI-errors are no guid. So yesterday I tried to figure out what the problem was, and somehow fixed it …

This is about Pond. If you have no idea what that is but don't want to click on the link, I shall quote directly; Pond is not email. Pond is forward secure, asynchronous messaging for the discerning. Pond messages are asynchronous, but are not a record; they expire automatically a …

Does anyone remember their first website? I know I was a nine-year-old with Microsoft Word and "Save as HTML", which seems like a decent reason to forget it, even if it was Pokemon-themed. Given my complete lack of gainful employment at the time, I took to website-making as if it …
