scaling web apps

A little video, thin on detail of course, but hints at some home truths on building/designing scale-able applications (and i’d go so far to say that they are applicable to ALL applications not just webapps)

Of course, I know Ben Rockwood like’s his solaris and F5′s – but that’s not going to surprise many (and I just LOVE f5s)

And here’s a blog entry with the details on /how/ that’s done:-

. . . basically as simple as:-

when HTTP_REQUEST {
  if { [HTTP::uri] contains "/popular_something/list"} {
    HTTP::respond 200 content "<fb:ref handle='[HTTP::uri]'/>"
  } else {
    pool facebook.application_server_pool
  }
}

the wet and the cold

Well finally put a few pictures from my Berlin trip up, should have taken my bigger camera though – but the strike by BVG didn’t help near the end of the stay, in the whole I think I liked Dresden more than Berlin – but I can’t really put my finger on why I feel that way.

Anywho, both were very nice – though it was pretty cold :(

recent applications window

This little snippet will give you a new little window for all those recent applications you launch – I seem to have picked up a habit for closing applications down when I stop working with them for an hour or two (pages etc.)
