This week was spent getting everything prepared for my where2.0 talk next week. One of the things I want to do in my talk is show some interesting visualisation based on all the location data I’ve stored in the past three years. I started this on Tuesday by creating a page on MapMe.At that anyone can use to graph the amount of time they’ve spent in places over the course of a year. The graphs give really interesting results and can give some genuine insights. For instance they show that in 2009 I tended to go to the same places more regularly whereas in 2008 I went to a greater variety of places. I’ve also seen that I went to London more often than I thought last year.
Once I had my graphs done it was time to work on my slides. Though I was originally a little nervous about whether I’d have enough material and spent most of Wednesday procrastinating I have ended up with nearly 40 slides which take me about 20 minutes to deliver. This is 5 minutes more than I have but I’m sure I can get it down, I’m just happy I have enough material!
The final thing I spent most of yesterday on was adding in support for foursquare synchronisation. MapMe.At is all about offering as many ways as possible to store your location and currently foursquare is one of the most popular location tracking services around. They have an API so it was obvious to me that I should support it. That’s gone well and I’ve got full support for pulling your check-ins and “shouts” from foursquare into MapMe.At. I hope to get support for pushing your location into Foursquare done before my talk but I can definitely add another logo to my slides now! That support should be rolling out onto the site pretty soon.
This week is the big week then. I give my talk at Where 2.0 actually quite late in the conference so I get to stress about it all the way through. Hopefully it should go ok but wish me luck!

Last week I was intending to spend on all mapme.at, all the time. Things didn’t quite work out so well but I did get some stuff done. The week started slowly as I procrastinated due to jet lag and generally not feeling like getting back to “work” after my holiday. Most of Monday was spent catching up on the bits of client work that had come in during my three weeks away, I also booked in a full day of client work on the Thursday to sort out some problems a client was having.
Tuesday I decided to take a trip into town and debug the problems we’ve been having with the Mersey Ferries on mapme.at. For some reason their positions haven’t been updating on shipais.com and I wanted to see with my own eyes that they were running. Soon after I got to the ferry terminal Royal Iris turned up to confirm that they were running fine. I decided not to pay for a trip myself so that I could talk to the skipper, good thing too as when I got home later in the afternoon I found they’d randomly started working again that morning!
On Wednesday I finally got going with some more work on mapme.at. First thing I needed to do was fix a problem that was causing duplicate places to show up due to the recent updates. Currently when a user looks at an area and they’re zoomed in enough I always download data from cloudmade, de-dupe it against data I’ve already cached and then add any extra records to my database. Cloudmade provide their own IDs for their results and I had assumed that these would be unique, I had also de-duped against the OSM IDs but a bug in that code had stopped it from working. It turns out the IDs provided by Cloudmade change (every time they do an OSM import I’m guessing) but they’re also unnecessary for my purposes – I will only use a result if it has an OSM ID anyway – so I’ve switched to de-duping on the OSM IDs only and everything seems to be working now.
On Friday I got most of the Facebook work finished, on my development version I can now attach a Facebook account to an existing mapme.at account and use Facebook Connect for login and signup. I haven’t pushed it live yet as I want to improve the signup process a little but it’s definitely getting there.
This coming week I’ve got a trip to London (today) to talk about some more client work but hopefully I’ll get some more stuff done on mapme.at today. I’m actually hoping to get GPX file import working so that I can have a lot more data for visualisations for my Where 2.0 talk. That’s also going to be the main thing I’ll be doing this week, trying to get my talk completed and ready for handing over on Friday!

WhereCampEU was this past weekend and by all accounts it was a blast! In case you don’t know, WhereCamp is based on the BarCamp model meaning that it’s a conference which is free to attend at which anyone can speak. The schedule is blank until the day of the conference when any of the attendees can announce their talk by putting it on “The Wall”: a big grid drawn out using masking paper allowing you to choose a time slot and a room.
It may have started out blank but the schedule was packed with great talks by the time the conference got going. I tried to go to as many as possible but, especially on the first day, many of the rooms ended up full to bursting. I was also tired because I’d just got off a 24 hour flight from Sydney so I did end up missing a few slots. Harry’s already posted photos of the wall and the talk titles have been copied onto the wiki, now it’s just up to the speakers to add some info about their slot (I’ve only just done mine).
The first talk I went to was about “GeoPrivacy, Your thoughts”, a discussion introduced by Chaitanya. It was interesting but most of the discussion was about privacy on the internet generally, rather than specifically location privacy which interests me most. I later caught the end of the Pedestrian routing talk as they came to the conclusion that for ideal results it really would depend on the user (a young female is likely to want to walk down different streets to an older male, probably). I also found a talk about using Apple’s iPhone “MapKit” library quite interesting as so far I’ve only used the route-me library. It also gave me the opportunity to plug my LocationManagerSimulator code. There was a few talks around the concept of “place” too, with my recent switch on mapme.at to using “places” these were quite interesting.
The evening involved geo-beers kindly sponsored by Axon Active:
Day two started for me with my own talk on Hacking Location into Hardware. I had intended to discuss my “Weasley Clock” a little and talk about how it worked. In the end I think I just rambled on too much and probably didn’t actually help people to understand how either the hardware or the software was put together, but hopefully I was entertaining at least.
I actually quite enjoyed the talk titled “A little light relief. Using global terrain data in your maps”. I only really attended because it promised light relief (and I only just got the pun today!) and because it was being given by an old colleague – Simon Lewis but it ended up being quite interesting and inspired me for some visualisation I need to do soon. The talk covered various aspects of Simon’s attempts to add terrain and relief shading to maps using a selection of open source tools.
I have to mention that one of “my” biggest contributions to the event was actually the logo, which I asked a friend to produce. Though I knew the logo was good originally it looked really great when printed out and mounted on posters, t-shirts and blog posts so I’ll definitely thank Sophie Green for producing that. I’ve used her for my mapme.at business cards before and always been happy with the results.
And there’s more geotastic geogoodness to come with Where 2.0 in two weeks. I will be talking about my experiences of tracking my location for the past few years in a session titled Why I Track My Location and You Should Too. It’s based on the session I’ve given at a few events already but should have fully new material. Maybe this time I’ll actually answer the question of “why?”, but more likely I’ll just show more pretty visualisations and hope no-one notices!

Just got back from a three week holiday to Australia and Singapore (well, in fact I still haven’t actually made it back, I’m on the train home from London after WhereCampEU!) Most of this was written on the train to Heathrow on the 19th February, unfortunately I didn’t really get time or sufficient internets to post it sooner. Hopefully next week’s will be up faster!
Another busy week as I prepared for my holiday which I’m now on! As mentioned last week my focus was supposed to be finishing off the mapme.at features while also mopping up the scraps from the client work I’ve done recently. I also ended up with a new day’s worth of client work which I’d quoted for a few weeks ago but forgotten about. I had finished the bulk of the client work that I’d been planning by Tuesday lunchtime but annoyingly I did find it kept springing back as my numerous related tweets will show. I had hoped that with all this “just one more thing” that someone might have paid me before I left, but alas no.
But enough about client work. The “place based check-ins” for mapme.at that I mentioned last week came along really well and I managed to get the code live on Wednesday (17th February). Since then there’s been a few tweaks here and there but as far as I can tell it all went out without any major problems. I put a blog post up about the changes so take a look at that for more information on those.
Something I forgot to mention from lunch last Friday was that Adrian McEwen asked me if I would like him to take my Weasley Clock to Maker Faire UK. Adrian was there last year and his famous Bubblino was filmed by the BBC. Maker Faire is all about interesting hardware hacks and so my clock should definitely be welcome there. Unfortunately it’s on the same weekend as WhereCampEU so it’s a good thing that Adrian offered to take the clock for me. I’ve wanted to come up with something better for it to show than my location as, even with my current travels, it tends not to change much over the course of a few hours. Something more interesting would allow me to demonstrate the clock more actively at conferences. Adrian suggested we use the mapme.at accounts for the Mersey Ferries so I made a few changes and got the clock showing that.
There’s three ferries but usually only one or two of them are active so the 2 hands of the clock can be utilised. When on their standard route the ferries travel between 3 ports – Liverpool, Seaforth and Woodchurch. Other than that they tend to either be in open water or moored in the docks. Using the new place-based functionality I was able to make sure that all the ports and mooring points were in as favourited places with labels for all the accounts. I then updated the clock’s Arduino code so that it could handle 6 different locations (instead of the existing 4). It seems to be working ok but unfortunately before I handed the clock over to Adrian the ferries didn’t seem to go anywhere. I’ve only described 5 of the 6 “places” so far… I took the opportunity with the redesign of the clock face to add a “Mortal Peril” option which should now occur when the ferries are doing tours down the Manchester Ship Canal!
Now I’m back from my holiday I’m sure I’ll have to spend some time over the next few weeks sorting out client requests that have come in while I’ve been away but I’m really hoping to get some more time to work on even more mapme.at features. I’m speaking at Where 2.0 in two weeks and so need to get a talk written with some good visualisations, and want to have a few products I can announce too.
