Testing Turing?

Stephen Pulman gave the Wheeler Lecture in our department this afternoon; an excellent discussion about whether current machine-learning techniques would ever allow us to build a machine that passes the Turing Test.

It made me wonder about the value of a variation on the theme, which I propose to call the Meta-Turing-Test.

It which would work like this:

Can we build a machine which, given a Turing Test scenario, can work out whether the responses are from a human or a machine, even when a human can’t?

Reviewing Amazon reviews

One of the best things about shopping online is the ability to view other purchasers’ reviews. But it is also remarkable just how foolish some people can be when reviewing a product.

I’m talking about the reviews that give something 5 stars, with the explanation: “I haven’t opened this yet but I’m sure my son will love it”.

Or the ones that slam a product with 1 star: “Arrived a day late and the postman left it in the wrong place.” So you want to punish your postman by telling people this isn’t a good camera, say? How does that work?

Discussing this with my friend Mac in the pub last night, we came up with a simple solution: When writing an Amazon review, you should be asked for separate ratings, as you are with TripAdvisor. They might be:

  • Purchasing, delivery, packaging and support
  • Quality of the product
  • Value for money

The first one should then become part of the rating of the supplier, not the product.

You could just have one other value, but splitting it into two like this might make people think a bit more, and allow you to take your price sensitivity into account when making a decision.

And someone who gives everything 1 star is probably just grumpy and their opinion should be weighted accordingly!

Then you could make more informed decisions like “This seems good, but I don’t want to buy it here”, or “I know this is isn’t great, but I just want something cheap”.

Viticulture

I’m used to labels on bottles of wine telling me that I should expect a ‘hint of blackcurrant’ or ‘subtle aromas’.

But in Portugal recently I had a (very drinkable) wine from a vineyard whose marketing department had, perhaps, become a little over-excited.

It’s nice to know there are still jobs out there for people with Literature degrees, isn’t it?

It’s not all bad in Zuckerland…

I left Facebook a little over a year ago, and hadn’t really felt any desire to return even before the recent round of news stories.

This NYT piece by Kathleen O’Brien gives an interesting and more positive viewpoint, though. But where are the ‘lifeboats’?

Is it time to revisit some of those other social networks on which I’ve had accounts in the last few years that never quite made it? I wonder how many of them are still in business…

Seen it before?

Here’s a handy site: TinEye. It’s a reverse image search.

If you’ve got an image on your machine and don’t know where it came from, or you find it online and wonder where the original lives or who uploaded it first, this can help.

I learned about this from Terence Eden, who has a great example on his blog showing how it can be useful…

This is your life

This is either fascinating, useful, or scary, depending on your point of view.

I’m usually logged in to my Google accounts on all of my devices, because I really appreciate the synchronisation of my history, finishing YouTube videos on one device that I started on another, and so forth.

Subconsciously, we all understand that Google therefore knows a lot about us. But if you go to:

https://myactivity.google.com/myactivity

you can see it all laid out before you.

For me, amongst other things, it shows things I’ve searched for, YouTube videos I’ve watched, posts on StackExchange, areas I’ve explored on Google maps, and so on. I generally use Safari, but if I were a more regular Chrome user, there would be a great deal more of my online activity listed here. (If you try this, then switch to ‘Item view’ for a blow-by-blow account.)

This timeline is also searchable, which is very useful for the more forgetful amongst us.

Now, if you subscribe to the ‘Big Companies are Bad’ philosophy, especially in light of recent Facebook news, this would be terrifying, though if you’re of that frame of mind you’d probably not log in to accounts on these services anyway, in which case your record will be less detailed, but you’ll use a lot of benefits too. And Google does offer you plenty of control over what they store, how much ads are personalised, etc. And you can delete your record of past activities.

Wherever you come on the paranoia scale, it is worthwhile and educational, I think, to visit such pages from time to time to develop a clearer understanding of what’s being recorded behind the scenes.

Nibble

Ah, so here’s why my shiny new lawnmower isn’t getting as much use as it might…

Our spaniel is sitting looking out of the patio door, and positively quivering with excitement…

Zooming in the rain

On Wednesdays, there’s an interesting group of catering vans that collect at the far end of the West Cambridge campus, and I like to go there for lunch.

But it’s a bit of a distance, and the weather today was bad, so it was important to find the most appropriate method of transportation…

Everything stops for tea

There are some tunes that are so catchy, they stick with you for ages.

I think I heard ‘Everything stops for tea’ about three or four decades ago, and probably only once. But the wonder of modern search engines is that they allow you to go back and renew your acquaintance with the things that formed those neural pathways all that time ago…

Adding custom ringtones to your iPhone using iTunes

In case you’re Googling for it, or in case I forget how to do it…

If you search online, you can can find various articles about how to take an MP3 or AAC audio file and make a .M4R-format file which an iOS device can then use as a ringtone. I’ve had a bit of Gilbert & Sullivan as mine for years, and have probably infuriated and/or amused those around me in equal measure when my phone starts announcing that I am the Captain of the Pinafore…

I lost this, though, in a recent wipe and re-install of my phone, after which I discovered that iTunes no longer makes it at all obvious how to put these custom ringtones onto your device. It’s easy if you buy them on the iTunes store, of course, but otherwise no amount of dragging and dropping would get my old favourites into iTunes or onto my phone.

But it turns out that there is still a way, and it’s documented some way down on this Apple page. As a quick summary:

  • Connect your phone to your computer, so it appears in the sidebar of your iTunes
  • Go and find your ringtone(s) in the Finder or Windows Explorer and COPY them.
  • Select the ‘Tones’ section of your device in iTunes and PASTE.

This works fine for me in iTunes 12.7 – no dragging and dropping needed. You should then see your ringtones, and be able to choose them in Settings > Sounds on the iPhone.
