+1 button

As an experiment (and before I let anyone go anywhere that near my employers precious website with it) I added the google +1 button to this blog today.
Unfortunately while I understand the idea of giving a bit of content an Big +1 I can't see where anyone would know that I've +1'ed anything.
If you have more of a grip of reality than I do, do let me know!

UPDATE! I found out, you need to use google.com not google.co.uk[1].. hardly had I done this and +1'ed things than +1's started showing up in my search results.. 

[1] I had to go to my google profile, enter a search term in the search box, then click "reset search tools" and I was on google.com instead of .co.uk

Colleagues go mad for "cheap" TV

OMG, get-a-cheap-tv fever gripped the workplace today as my colleagues (who should've known better!) went on a fevered buying spree after woolworths appeared to be selling Sharp 37" & 42" LCD TV's for £150.
Sadly no-such-luck boys and girls, woolies T's & C's retain the right not only to cancel your order but also to ... ".. continue with the order at the correct price" which might embarrass those who chose to order several of the two grand machines!
There were reports of orders being cancelled, however the on-line price was still £150 as this post "went to press", so if anyone else fancies a go...

Quote of the [specify period]

This [period]'s quote is from Nicola Morrison, ScottishPower online manager quoted on computerweekly.com, here, in a piece which quite frankly looks like marketing blurb placed by a PR agent on a day when the editor was hungover.

Anyway, Nicola have an award for improving customer service not by answering customers questions but by analysing them!

Working with [tech co][1] has ... given us an unparalleled insight into our customers' requirements through the ability to analyse the questions they are asking.

[1] I'm not going to repeat the name of the company involved, I don't want to draw attention to them!

Note to self, how to get row numbers in a MySQL SELECT

I've often wondered, idly, how to get MySQL to output a row number column, which would rank sorted and grouped results.
Well thanks to this excellent post I've found out how:

SELECT *, @rownum:=@rownum+1 as rank FROM ( 
-- Your Query Goes in Here
        SELECT t.*
        FROM table t
        WHERE something
        group by 2,3,4
        order by 1 desc limit 20
    ) day_rank, (SELECT @rownum:=0) r;

Note to self, want stats on nfs usage, try this

I thought I'd put this in as well, since I had to google for it, using -n will make iostat provide you with stats for nfs shares too.

iostat -nh 5

You can also use nfsstat

nfsstat -cvn -o nfs
