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 …

Today is St. Patrick's day, which means there's a lot of this online:

Lá Féile Pádraig shona duit

or this:

Lá Fhéile Phádraig sona duit

or basically any variation of:

Lá F(h)éile P(h)ádraig s(h)ona duit

which all roughly mean 'Happy St. Patrick's Day' in …

I'm gradually migrating old posts over from my WordPress blog, which will be backdated, ruining the timestamps-through-commits system that could have been, but never was. Hopefully the validity of the alleged timestamps on these posts will never be important for anything.

Comparing the new post[1] with the old also …

I'm (arguably) a data scientist, so I need data to do science. A problem with data is that it's all over the place, a natural and unsurprising consequence of its many origins. Producing databases seems to be a hobby for bioinformaticians, which also includes databases of databases (Bolser et al …

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 …

Background: I am running python with Theano on a GPU, and I care about speed.

Scenario: I have a largeish matrix (C) which is stored as a shared variable, and I need to update a subset of the rows (modified_rows) by some other matrix (C_delta). What should I do?

Initialising …

I try to record useful one-liners for future reference. I forgot to write down what this one does:

    mv $f ${f##START}.${f%%${f##START}}

This awkwardly-timed (time-zone troubles) blog post is atonement for my carelessness. Like all one-liners it looks complicated but is pretty simple. It does this:
