Haywire

kellabyte’s hack in progress — ‘an asynchronous HTTP server framework written in C. The goal of Haywire is to learn how to create a server with a minimal feature set that can handle a high rate of requests and connections with as low of latency and resource usage as possible. Haywire uses the event loop based libuv platform layer that node.js is built on top of (also written in C). libuv abstracts IOCP on Windows and epoll/kqueue/event ports/etc. on Unix systems to provide efficient asynchronous I/O on all supported platforms.’ Outperforms libevent handily, it seems. Apache-licensed.

spoofing the samsung smart tv internet check

If this kind of bullshit — a HTTP GET of an XML file from www.samsung.com — is how the Samsung Smart TV firmware decides if the internet is working or not, I dread to think how crappy the rest of the code is. (At least in Netnote we performed a bunch of bigco-domain DNS lookups before giving up…)

ImperialViolet – No, don’t enable revocation checking

…because it doesn’t stop attacks. Turning it on does nothing but slow things down. You can tell when something is security theater because you need some absurdly specific situation in order for it to be useful.

Uplink Latency of WiFi and 4G Networks

It’s high. Wifi in particular shows high variability and long latency tails

vim-flake8

vim-flake8 is a Vim plugin that runs the currently open file through Flake8, a static syntax and style checker for Python source code. It supersedes both vim-pyflakes and vim-pep8. Flake8 is a wrapper around PyFlakes (static syntax checker), PEP8 (style checker) and Ned’s MacCabe script (complexity checker).
