The Winterlong Trilogy by Elizabeth Hand

Gothic, Grand Guignol-drenched post-apocalyptic science-fantasy. "Febrile" is a word that comes to mind – the language is overstuffed, it's dense with references to fantasy and folklore, and the characters are run through the wringer. Not the last of her novels to feature a transmogrified Washington DC as a primary venue.

Waking the Moon by Elizabeth Hand

Roman á clef and supernatural romance (in the traditional, not Twilight sense) featuring the hidden war between the Benandanti, a sect of nasty old patriarchal quasi-Catholics, and the forces of Othiym Lunarsa, goddess of a long-suppressed matriarchal death cult. If Camille Paglia ever read this, she probably loved it, but the central story is basically an overheated, fantastic version of Whit Stillman's Metropolitan and so th

I've known people at nodejitsu for years, since before the company even existed. I still consider many of them friends. That said, somebody over there has lost their mind.

Trademarks are an important part of open source. They protect the integrity of the trust that is built by any project. A classic example of why this is the case is Firefox. Suppose that a malware producer takes the Firefox codebase, which is free and open source, packages up their malware with it and then releases it as "Firefox". Then they buy search advertising and suddenly their bad and malicious version of Firefox is the first result on search engines across the web. This is clearly a bad thing for Firefox and open source everywhere, but what can Mozilla do to protect their community of users?

They can't enforce a software license since the use is permitted under the Mozilla Public License. They can, however, enforce on these hypothetical bad actors using their trademark on the word "Fi

When you build a community you're creating a culture. That culture will be about more than the code, the modules, or the language. The people you draw in will have their own biases and behaviors that impact the kinds of people you continue to draw as you grow.

Cultures will naturally fight behavior that is divisive. That is, behavior that is divisive to the established members of that community. As a community grows larger it is harder and harder to change what the culture finds acceptable because changing it, even if it is inclusive in nature, is disturbing and divisive to existing membership. Fighting for change in established cultures means dealing with a lot of dismissive language and attacks for the "tone" of your argument.

That is why it is so important that a culture becomes comfortable with aggressively fighting exclusionary behavior. While it is certainly more beneficial to make pro-active steps to increase diversity we cannot be dismissive of the effect that passionate reactions to poor behavior
