Hacking HTTP Host Headers, Collaborative Coding, Glitch is the Overloaded Essence, and Crazy Culture

  1. Practical HTTP Host Header Attacks — lots of cleverness like So, to persuade a cache to serve our poisoned response to someone else we need to create a disconnect between the host header the cache sees, and the host header the application sees. In the case of the popular caching solution Varnish, this can be achieved using duplicate Host headers. Varnish uses the first host header it sees to identify the request, but Apache concatenates all host headers present and Nginx uses the last host header.

  3. Too Momentous for the MediumWhatever you now find weird, ugly, uncomfortable and nasty about a new medium will surely become its signature. CD distortion, the jitteriness of digital video, the crap sound of 8-bit – all of these will be cherished and emulated as soon as they can be avoided. It’s the sound of failure: so much modern art is the sound of things going out of control, of a medium pushing to its limits and breaking apart. The distorted guitar sound is the sound of something too loud for the medium supposed to carry it. The blues singer with the cracked voice is the sound of an emotional cry too powerful for the throat that releases it. The excitement of grainy film, of bleached-out black and white, is the excitement of witnessing events too momentous for the medium assigned to record them. (Brian Eno’s words)
  4. Where the Happy Talk about Corporate Culture is All Wrong (NY Times) — I think there are two types of happiness in a work culture: Human Resources Happy and High Performance Happy. Fast-growth success has everything to do with the latter and nothing to do with the former. Lazy false opposition, and he describes an asshole-rich workplace that would only please a proctologist.
