Alex Payne — Bitcoin, Magical Thinking, and Political Ideology
Working in technology has an element of pioneering, and with new frontiers come those would prefer to leave civilization behind. But in a time of growing inequality, we need technology that preserves and renews the civilization we already have. The first step in this direction is for technologists to engage with the experiences and struggles of those outside their industry and community. There’s a big, wide, increasingly poor world out there, and it doesn’t need 99% of what Silicon Valley is selling. I’ve enjoyed the thought experiment of Bitcoin as much as the next nerd, but it’s time to dispense with the opportunism and adolescent fantasies of a crypto-powered stateless future and return to the work of building technology and social services that meaningfully and accountably improve our collective quality of life.

MP Claire Perry tells UK that worrying about filter overblocking is a “load of cock”
the bottom line appears to be “think of the children” — in other words, any degree of overblocking is acceptable as long as children cannot access porn:
The debate and letter confuse legal, illegal and potentially harmful content, all of which require very different tactics to deal with. Without a greater commitment to evidence and rational debate, poor policy outcomes will be the likely result. There’s a pattern, much the same as the Digital Economy Act, or the Snooper’s Charter. Start with moral panic; dismiss evidence; legislate; and finally, watch the policy unravel, either delivering unintended harms, even to children in this case, or simply failing altogether.
See https://www.openrightsgroup.org/blog/2013/talktalk-wordpress for a well-written exploration of a case of overblocking and its fallout. Talk Talk, one UK ISP, has filters which incorrectly dealt with IWF data and blocked WordPress.com’s admin interface, resulting in all blogs there become unusable for their owners for over a week, with seemingly nobody able to diagnose and fix the problem competently.(tags: filtering overblocking uk politics think-of-the-children porn cam claire-perry open-rights-group false-positives talk-talk networking internet wordpress)

ie. “i18n”, “a11y” etc.
According to Tex Texin, the first numeronym [..] was “S12n”, the electronic mail account name given to Digital Equipment Corporation (DEC) employee Jan Scherpenhuizen by a system administrator because his surname was too long to be an account name. By 1985, colleagues who found Jan’s name unpronounceable often referred to him verbally as “S12n”. The use of such numeronyms became part of DEC corporate culture.[1]
