Dear Lazyweb - Command Line YSlow!
The title pretty much says it all, I'd like a command line version of YSlow! (what is it with
Yahoo and !s) that I can run from cron and import in to a nice
spreadsheet for trending and site comparisons.
I don't have XUL on my list of things to play with so I'll give it a couple of months and watch someone else implement it. Hopefully.

More Memory Than Sense
My recent bugbear is - servers with inaccessible memory.
You go and spec a nice new server with say 8Gb of RAM (a little box),
you install Debian, you start adding applications to the machine and then a
couple of months later some anal sysadmin comes along, does a free
-m and mutters about under-specced virtualization servers when he sees
-
total used free shared buffers cached
Mem: 3287 225 3062 0 24 149
For those of you not paying attention - the machine isn't using over half of it's memory. So first of all how do you spot this and secondly how do you fix it?
If you're on Debian then the spotting is easy (for some hardware) -
apt-get install lshw
lshw -class memory | grep -A 4 '\-memory'.
If the size is bigger than the total from free then you've got
wasted resources.
The fix? Install the right bigmem kernel. And then recompile VMware server. Dammit.

Back in to the fold!
It's been a while since I posted anything here but now seems like as good a
time as any to get back in to the wider world of tech. Where's a good place
to start? Since this years YAPC::EU only has two or three talks I want
to see I've decided to use the cash (and holiday time) and invest them
in to PyCon UK instead.
