Running tcpdump on remote hosts with no storage

If you have tcpdump on your embedded home router and you want to see what traffic your crippled phone is doing, you can dump traffic on the router and visualise it on your main workstation using wireshark.

  1. On the remote host, create a FIFO
remotehost# mkfifo /tmp/tcpdump

Welcome in many languages (in JSON format)

Today I wanted to implement a multi-language greeter for an application, and I ended up on http://www.omniglot.com/language/phrases/welcome.htm

I extracted all the welcomes from the page using jQuery, serialized them as JSON and processed them using Ruby:

welcomes = x.inject({}) {|h, (lang, val)| val.gsub!(/\(.*?\)/, ''); vals = val.split(%r{\s+/\s+|\n}); vals.map! {|val| val.strip!; val.gsub!(/^\w+ -\s+|- \w+$|^lit.*|>.+$/, ''); val.strip!; val}; vals.flatten!; vals.reject!(&:blank?);; h.update(lang => vals) }

FontAwesome.EOT that works with IE8, as it has Fontname, Family Name and Name for Humans all set to the same "FontAwesome" value. Refer to http://stackoverflow.com/a/12459447/80969 ... Internet Explorer, as usual, is the crappiest crap of all craps.
