Ridge Regression Revisited

I’ve been neglecting the blog a bit lately, partly because I haven’t had much to say and partly because I’ve been a bit busy with other things.

Institutional Alzheimers: A Culture of Secrecy and the Opacity of #GAMEDEV Work

[Cross Posted at Culture Digitally] Yesterday, Todd Harper (@laevantine) tweeted a reflection on several other blog posts responding to recent news that Irrational Games was closing.

Loligo pealeii (squid) data dump

A few months back, I announced the khmer protocols project, an effort to write down an explicit, open protocol for transcriptome and metagenome assembly.

For the second time, I’m requiring students to use github for their homework; unlike last year, I now understand pull requests and have integrated them into the process. How does it work, basically?

Futebol Nation: The Story of Brazil

The Garrincha of futbology, David Goldblatt, admits he’s neither Brazilian nor a Brazilianist as he begins his recent public lecture at Pitzer College in California. Then, like Garrincha, he feigns left, goes right through through Brazil’s World Cup history, pivots on slavery, Lusotropicalism and GINI coefficients, does a give-and-go with Mario Filho, dribbles around Benedict …
