Famous Potato

2009-11-04T14:46:00.000-08:00

Google are trying to sell me AdWords. They sent me an email today offering $100 of free credit. It was enough to make me go and check the analytics page for the site.

40,665 visits came from 160 countries/territories

Wow. This is the total count for the 3 years the site has been live, so it's not a large amount of traffic, but it's more that I would expect for a static page with no promotion or advertising at all. The reason for the high hit rate is search rankings. What on earth are people searching for to find howbigismypotato.com? Turns out they're looking for images of a potato, and Google images has indexed the picture I took of my potato in my London flat as one of the top examples of a potato image. What a beautiful sight:

The rankings change over time, and I can see that reflected in the varying traffic volumes hitting the site. It also seems that each country-specific instance of Google has its own rankings. Of course most of the hits come from Google in English speaking countries; who is going to ask for a picture of a "potato" if you don't use that word? I happened to notice that in recent months Indonesia is the 3rd most popular country as a traffic source (behind the US and the UK), while early on there was hardly any traffic coming from there. What has changed in Indonesia?

Open question: is there a relationship between a region's potato production or consumption and visits to the site? I'm glad to say that's something I don't have time to investigate.

Why?

The original inspiration for this project was an incident at home. My flat-mate Dave wanted to microwave a potato. How long would it take? Handily the mirowave had a baked potato button, but it needed him to type in a mass. With no scales available, he asked for my help and I devised a see-saw like device involving a wooden spoon, a spatula and a block a cheese. We were able to get the potato to balance against the block of cheese and we could measure the distances to the pivot with a tape measure. The final step was to divide a couple of numbers to find the mass we wanted. I turned to my laptop and used its calculator. 346g - success! Ironically the microwave only wanted a measurement to the nearest 100g, so we probably could have just guessed.

This incident was silly in a number of ways, but the thing I found most ironic was that the final step in our low-tech process invloved an expensive computer - not low-tech at all. How many people, I speculated, lacked scales in their kitchen but did have a computer close to hand.

A week later I was showing off to my girlfriend, telling her about my potato weighing skills over a romantic dinner. In the chat that followed, howbigismypotato.com was born. It was going to be fun, very silly, and surprisingly hard work.

Warning! Damage!

2006-10-07T20:47:00.000-07:00

Here's a bit of a problem that somebody pointed out to me. Computer screens aren't actually designed to have things held up to them, so there's a possibility that things might go wrong while trying to measure a potato. Just in case, I've decided to put in these warnings. I've also included them in a disclaimer just in case something really bad happens.
I think there are two main things to be wary of:

Scratching or denting the screen. Be careful with the edge of your credit card, and your finger nails when holding it. Only measure relatively clean potatoes; big chunks of earth could be quite abrasive. If necessary, it would be possible to measure a potato wrapped in a clear plastic bag which would be less abrasive.
Damaging other computer components. Laptops are really common these days. Laptop keyboards are notorious for allowing bad stuff to enter between the keys and cause serious damage below (usually the processor is directly underneath the keyboard). While measuring a potato does not involve the worst laptop poison (hot sugary coffee) it's conceivable that earth or even water could find its way between the keys during the process.

So, you've been warned. Please be careful and enjoy a safe measuring experience.

The internet is a small place

After an embarrassingly long gap of inactivity, I'm making some progress again. There's a shortish list of things to fix before I'll feel happy promoting the site. Top of the list was appearance; the markup and CSS is respectably structured, but it still doesn't look great. I did a little googling for inspiration. Cameron Moll's impressive portfolio caught my eye. I especially liked the look of what he did for Joyent. So who are these Joyent people? Turns out it's part of the same outfit as TextDrive, a hosting company. The second thing on my to-do list? Hosting. And I'd heard good things about TextDrive via the Ruby on Rails crowd. In fact I'd already started checking out their prices. And there was the freaky moment, the same page open in two Firefox tabs via completely different navigation. It was a sign; I bought a server from TextDrive straight away.

No more sliding, just dragging

2006-07-06T14:54:00.000-07:00

The sliders have gone. Now both calibration and measurement use the diagonal "drag me" icon. The hardest part of this exercise was learning the required javascript to intercept mouse events properly. In fact it was so hard that it isn't finished yet: it works fine in Firefox but it's utterly broken in IE. That's a problem for another day, probably a day that I have a PC available so I can actually run IE rather than guessing how it behaves.

There is some subtlety to the behaviour: on the calibration page the credit card outline maintains its aspect ratio, while the measurement potato outline can be stretched to any shape. This distinction probably won't be noticed by a user.

I had to think about the maths for a while. Confusingly I am now measuring two dimensions of a three-dimensional object. I toyed with inferring that the shortest measured dimension was probably closest to the unmeasured dimension, in which case I would square the short dimension and multiple by the long one to get the volume of the containing cuboid. However, I decided it was simpler to just raise both dimensions to the power of 1.5 and be done with it. I struggle to find a physical analogy for a length to the power of 1.5, but the maths seem to work.

One point calibration

2006-05-04T15:37:00.000-07:00

Due to tiredness, and the prospect of yet another 11 hour day in the office tomorrow, I was only able to measure one potato. Despite this rather pathetic attempt at calibration, it's a heck of a lot better than it used to be. It felt really good to hold the potato up to the screen and read the right answer back.

First calibration weighings

2006-05-04T14:24:00.000-07:00

After much time away from the project, I return armed with some brand new kitchen scales. They will be used to calibrate the system, so in effect these will be the scales that lucky people out there will use to weigh their potatoes.

Cosmetic Surgery

2006-04-09T15:14:00.000-07:00

Iteration 3 is complete. This time there was no new functionality, but cosmetic surgery to make the page more presentable - still very valuable progress.

CSS is hard

2006-04-09T14:42:00.000-07:00

CSS is cool. It's easy to get the basics to work well. However when I try to do something a bit more complicated, I don't find it very intuitive. I'm still near the other end of the scale from a CSS power-user. After most of a train journey back from Poole spent laying out just two boxes, I gave up and used a table. Yuk, but it works. Maybe with an internet connection and a bit more time I'll be able to fix it sometime.

Two pages of potato measurement action

2006-03-26T14:47:00.000-08:00

Iteration 2 is compete. I am no longer totally ashamed of how the thing looks, plus I (and my test users) are starting to get the feel of how this might actually work.

Corrupted password file

2006-03-18T11:01:00.000-08:00

I first bought hosting back in 2000 I think. On the recommendation of a friend, I chose Nexpoint, and bought their shared server package which was based on a Cobalt RAQ server. This has worked fine ever since, and on the few occasions that I've needed support (password reset and PHP reconfiguration) they have been helpful and efficient. On Wednesday I thought I'd try to upload the howbigismypotato files to my webspace, to try it out as a possible hosting option. I couldn't log in through FTP or SSH using any user I could remember, so with a sigh I submitted a support request to have the passwords reset. I was surprised to get this message in response:

The password file on your server has recently been corrupted. The server you are on is a cobalt linux server and cobalt no longer provides support for their servers.

Oh dear. How often does this sort of thing happen? I've never heard of it happening at work. It must be quite a nightmare in a shared hosting environment like the one nexpoint run. Amusingly all my web pages, including the dynamic stuff, was still working fine without me having looked at it for years. If I'd never tried to log in at the host level, I would never have known there was a problem.
Thankfully Nexpoint provided a good solution - moving all my files onto a newer server, and effectively setting me up a whole new hosting package. It all went through smoothly and I remain very happy with their service. Now it's time to get on with something more productive.

Rounded corners

2006-03-14T13:35:00.000-08:00

Drawing a rectangle is pretty easy, even if you are stuck using Powerpoint. Drawing rounded corners that are arcs rather than eliptical arcs turned out a little harder. Here's my first attempt at a credit card outline, based on the ISO dimensions. Seems OK apart from the small artifacts on the right-hand side. Maybe I should use slightly heavier lines. Maybe I should write "Bank of Potato" on it.

Spelling mistake

2006-03-14T12:29:00.000-08:00

Somehow I spelt "building" wrong in the URL for this blog. It's fixed now. The QA department will be sacked.

Baby steps with a slider

2006-03-13T15:34:00.000-08:00

Iteration 1 is complete. Small GIF grows and shrinks when you use the slider. I found the slider at Web FX, and it seems pretty clean. The page itself is just on my laptop for now; hosting not sorted out yet.

Got the domain

2006-03-13T13:19:00.000-08:00

It's not 1999 anymore, but even now you haven't started your .com adventure until you've bought the domain. I bought mine, with a little help from Claire, last night. So now we are showing the UK2 holding page. Why did I choose UK2? Because I've used them before, when I thought they were quite cheap, and they did the job just fine. I'm amazed that their pages don't appear to have changed in 5 years. I guess they must work.

The beginning

2006-03-13T12:56:00.000-08:00

was actually a few weeks ago. Full story to follow. In the mean time I'm starting this blog about building a silly website. Let's see how silly it gets.
