Great essay on sexism in tech, “brogrammer” culture, “clubhouse chemistry”, outsiders, wierd nerds and exclusion:
Every group, including the excluded and disadvantaged, create cultural capital and behave in ways that simultaneously create a sense of belonging for them in their existing social circle while also potentially denying them entry into another one, often at the expense of economic capital. It’s easy to see that wearing baggy, sagging pants to a job interview, or having large and visible tattoos in a corporate setting, might limit someone’s access. These are some of the markers of belonging used in social groups that are often denied opportunities. By embracing these markers, members of the group create real barriers to acceptance outside their circle even as they deepen their peer relationships. The group chooses to adopt values that are rejected by the society that’s rejecting them. And that’s what happens to “weird nerd” men as well—they create ways of being that allow for internal bonding against a largely exclusionary backdrop.(via Bryan O’Sullivan)

a utility to perform parallel, pipelined execution of a single HTTP GET. htcat is intended for the purpose of incantations like: htcat https://host.net/file.tar.gz | tar -zx It is tuned (and only really useful) for faster interconnects: [….] 109MB/s on a gigabit network, between an AWS EC2 instance and S3. This represents 91% use of the theoretical maximum of gigabit (119.2 MiB/s).
