IBM need help with statistics

Look at this infographic

The way I read this, before and after were the same.

So,”Stockholm convinced the skeptics to pay for a faster commute.”?

I’m assuming that means pay for an IBM traffic management system as I’m not exactly sure what was being paid for.  I’m don’t I agree the skeptics were convinced though from reading their infographic. The two key bits of data to prove their point are: “Before: Over 50% say no.  After: Over 50% say yes”

Now, I’m not a statistical genius, but I don’t imagine they’re doing too much rounding on these numbers.  If 60% said no, I’m sure they’d have told us. If 55% said no, I’m sure they’d have told us.  We don’t know how accurate their data is either, did they ask everyone or try for a representative survey?  They may be out by 10% anyway (let’s hope not).  To keep it clearly written,  let’s replace the word “Over” with “About”. Does that sound reasonable? Well it does to me so let’s do it.

Now let’s put the ‘after’ into the same context as the ‘before’. As “Over 50% said yes”, that’s the equivalent of “Under 50% said no”, or replacing Over/Under with About, that’s the equivalent of “About 50% said no”  Let’s rewrite their phrase:

Before: About 50% say no.  After: About 50% say no.

At least, that’s how I read it, but maybe it’s me that needs the help with statistics.

Caught in my spam trap – buildingmergers.co.uk

I’ve decided to start naming and shaming the people who spam me. I have an email address hidden in the code of one of my web sites. It doesn’t display to visitors but robots will read it.  To give the spammers a sporting chance, the email address is nospam@….mydomain… I then email them to ask where they got the address from.

Their response to asking where they got the email address from?

No reply from ibenson@buildingmergers.co.uk  (also the address on the web site)

Installing a new hard disk in a Mac = not fun

So I had to upgrade my mac hard disk. 12 months and I filled the 320Gb disk so I treated myself to a Seagate Momentus XT 750Gb disk.

It has NOT been fun. Problems so far include:

Initialise disk over the internet and restore from TimeMachine – fails to restore the recovery partition so cannot use FileVault2. Correct way: initalise disk over the internet and reinstall OS X Lion with a new temporary user that has a different user name (not one that’s within your TimeMachine backup). Then restore Mac from TimeMachine, then delete temporary user to keep things tidy.

BootCamp has been a nightmare. I eventually bought WinClone which has made things slightly easier. I got dual boot working, then setup FileVault2 which managed to prevent me logging in to the windows partition. I’m sure I had FileVault2 running before on the old disk with bootcamp and without any problems. Trouble is it takes hours for the encryption process, hours to clone the windows partition, hours to restore the windows partition. I have yet to get that working.

Now, I want to do some ruby coding and discover TimeMachine doesn’t save my ‘path’ information so Git didn’t work (it was backup up). TimeMachine also didn’t backup my /etc/hosts file (I had entries that weren’t important but finding them gone is a little disconcerting) and at the moment I can’t compile some software for a variety of errors.

Argghhhh!
