I send this link around quite frequently. It contains a truth we often forget: “Software is hard. The way to fix it is to fix it, not sweep it under the rug.” The OCD part is a tough thing to swallow. But it’s spot on. redhat.com/archives/fedora-dev

A list of (respectable) open access journals in mathematics: thehighergeometer.wordpress.co

Possibly because it's aimed more at math than CS, it doesn't include the two open journals I read and write to most frequently, J. Graph Algorithms (jgaa.info/) and J. Comput. Geom. (jocg.org/index.php/jocg).

"The record industry insists that all unauthorized copies represent lost sales. So Peter "brokep" Sunde, co-founder of #ThePirateBay, has built a machine that makes 100 copies per second of Gnarls Barkley's "Crazy," storing them in /dev/null (which is to say, deleting them even as they're created)."

Article by Ord, Toby
In collection: Basically computer science
Due to common misconceptions about the Church-Turing thesis, it has been widely assumed that the Turing machine provides an upper bound on what is computable. This is not so. The new field of hypercomputation studies models of...

Expecting to know math after only reading books is like expecting to speak a foreign language after you read a dictionary/manual.

The way we teach mathematics should include the stories of how each breakthrough was discovered.

I recently found some hilariously-named software that cuts PDFs scanned as two pages side-by-side into single pages.

I've definitely found myself affected by social cooling. On Twitter, I wouldn't tell jokes or make controversial statements because I knew all my colleagues and present/potential employers were on there. In my field (webdev), your reputation on Twitter can determine which jobs you land and which conferences you get invited to. Best just to be bland and cheerful if you want to fit in with the crowd.
