What I want from Amazon

I buy masses of stuff through Amazon. And I do take note of the reviews left by others. When you do a search, you can choose to order the results by average customer review, which is almost useful, but not quite.

The problem is that if there is only one review, but it’s rated 5-stars, that item will appear at the top. Similarly, an item could be unfairly blighted by a single negative review. I’m not so interested in things that were only bought by the vendor’s cousin, who thought it was great.

So, Amazon, could you come up with something like this, please?

“Sort by the median value where there are more than 5 reviews, and where there are 5 or fewer, by a value somewhere between the mean and the average rating used for all reviews on the entire site, weighted towards the former proportionately to the number of reviews.”

Ideally, a given user’s review would also be weighted to some degree based on the distribution of that user’s reviews for any other products as well. And I’d like to be able to tweak the parameters for my own searches.

Of course, any scheme like this could be gamed, so they’d probably need to keep the actual algorithm secret and change it from time to time, like Google. They could call it Q-Rank; I wouldn’t mind. This would also have another significant advantage:

They’d be able to fit it in the pull-down menu.

A handy tip for those who don’t have expensive fluid video tripod heads.

Passionflower: lateral strumming

 

Jon Gomm demonstrates some real lateral thinking on how to use a guitar.

 

Aerial Anthony Gormley?

This publicity stunt for the movie Chronicle is nicely done, I think.

British Pathé

Have just discovered that British Pathé have a splendid archive of “90,000 Historic Clips”.

Here’s a pleasing little example. (I remember meeting George Cansdale a couple of times in my childhood – he was a minor hero of mine.)

If you like these, you can also find a good selection of historic videos on the Internet Archive.

Beyond Reasonable Doubt?

We all know the courtroom drama, where the suspense is tangible as we wait for the jury’s verdict. But should such things actually happen, asks Richard Dawkins in a New Statesman article?

Extract:

You cannot have it both ways. Either the verdict is beyond reasonable doubt, in which case there should be no suspense while the jury is out. Or there is real, nail-biting suspense, in which case you cannot claim that the case has been proved “beyond reasonable doubt”.

Smart Energy – now it’s personal

PilgrimMy pal Pilgrim Beart gave a splendid talk at the IET last week, about smart energy monitoring.

45 mins of talk, 45 mins of questions. Well worth the time.

Humour for Geeks

If you’re an elderly Computer Scientist (i.e. older than about 35), you’ll enjoy James Iry’s post, A Brief, Incomplete and Mostly Wrong History of Programming Languages. Extract:

1957 – John Backus and IBM create FORTRAN. There’s nothing funny about IBM or FORTRAN. It is a syntax error to write FORTRAN while not wearing a blue tie.

1958 – John McCarthy and Paul Graham invent LISP. Due to high costs caused by a post-war depletion of the strategic parentheses reserve LISP never becomes popular. In spite of its lack of popularity, LISP (now “Lisp” or sometimes “Arc”) remains an influential language in “key algorithmic techniques such as recursion and condescension”.

Splendid stuff! – Many thanks to Dave Clarke for the link.

A Different World

A shot from my impromptu skiing trip last week.

Lots more photos here.

Sliding-Q

Geoff took some nice photos of me on the slopes today.  I’ve edited out the ones that made me look less cool.

 

 

If you read my earlier post, you may be amused to notice that the poles are not the same colour in all of these pictures!
