A simple 3-step plan to prevent abuse on Twitter
  • Bayesian filter to detect potential abusers, filtering on words, length of time the user has been active, number of tweets a user has sent, who the user has tweeted to, # of spam reports against the user
  • Anyone who is tweeted to on a regular basis by potential abusers gets flagged (not publicly visible of course) as being a target
  • Anyone who tweets at someone who is a target and triggers the Bayesian filter gets auto-suspended and has to submit a form explaining why they should be unblocked

Some notes on codes of conduct from a conference organizer's perspective

Some notes on codes of conduct from a conference organizer's perspective

  1. The customers of a Code of Conduct are the people whom it is protecting. For tech conferences, that means marginalized people.
  2. The Code of Conduct is a promise to its customers from the conference organizers that they will be in a safe space, and that they will be protected and given the benefit of the doubt in the event of something bad happening.
  3. Thus the wording of a code of conduct should be decided by its customers. The Geek Feminism wiki hosts an example code of conduct:
  4. The legal basis of a code of conduct is my right, as an event organizer, to kick anybody out of my private event for any reason, even if they have paid. This happens all the time, often with the most flimsy excuses:

If you, as a non-customer of the CoC, are not


Inclusion Rider

I'm lucky enough to get asked to speak at a number of conferences, and I want to make sure I use that privilege to help improve the state of the industry. As a result I've put together a list to make sure the conferences I speak at reflect my values:

For all events

  • Code of Conduct: There must be a code of conduct that is clearly visible on the front page of the website, and which covers all conference participants including sponsors. The code of conduct must include details on who to contact and guidelines on enforcement and reporting. A good sample code of conduct is available at
  • Speaker diversity: At least 40% of speakers (including keynote speakers) must be women or nonbinary folks, and if the conference is held in North America, Europe, or Australia/NZ, at least 5% must be of non-European origin. If you would like me to speak on a panel, there must be at least two women on the panel.
  • Bathrooms: There m

Stevey's Google Platforms Rant

I was at Amazon for about six and a half years, and now I've been at Google for that long. One thing that struck me immediately about the two companies -- an impression that has been reinforced almost daily -- is that Amazon does everything wrong, and Google does everything right. Sure, it's a sweeping generalization, but a surprisingly accurate one. It's pretty crazy. There are probably a hundred or even two hundred different ways you can compare the two companies, and Google is superior in all but three of them, if I recall correctly. I actually did a spreadsheet at one point but Legal wouldn't let me show it to anyone, even though recruiting loved it.

I mean, just to give you a very brief taste: Amazon's recruiting process is fundamentally flawed by having teams hire for themselves, so their hiring bar is incredibly inconsistent across teams, despite various efforts they've made to level it out. And their operations are a mess; they don't real
