• Windows Phone app download stats

    I’ve installed the Windows 10 preview build on my laptop, and one side-effect of this is that I can’t get the Windows Phone 7.1 SDK bits to work (they won’t install). Hopefully they will be supported eventually in later (or the final) versions of Windows 10, but for now it means I can’t do any 7.1 builds of my phone apps using my laptop.

    I thought it would be interesting to find out how many 7.1 users are still downloading the app, to gauge whether I should still try and support the older devices. I took a look at the download data for one of my apps (Aussie Toilets) for the last 3 months:

    Graph showing percentage of Windows Phone OS versions. 7.1 at 13%, 8.0 at 33% and 8.1 at 53%

    So, just over half of the downloads were using 8.1 and a third are still on 8.0. Only 13% are still on 7.1

    What about handset manufacturers? No surprises there – Nokia with 90%.

    Bar graph showing handset manufacturers by percentage. HTC with 8%, LG with 1%, Nokia with 90% and Samsung with 3%

    And the same for country/region – Australia with 89%. I assume the other countries were just curious, international travellers or possibly even immigrants who preferred their original country’s settings.

    Bar graph showing downloads by region. Australia with 83%, other countries all below 6%

    And finally just out of interest, age groups:

    Bar graph showing age groups. Reasonably even spread from 15 - 22% across age groups

    That’s a nice even spread across the various age groups.

    So that might mean that for now I’ll have to leave the 7.1 users high and dry. If support for installing the old SDK is fixed, then I can look at giving them a few more updates in the future. Alternatively I might be able to convert my old system image into a VHD file and then I can boot the laptop back into the old Windows 8.1 image. I’d have to trim down the VHD file so it can fit onto the 500GB SSD I’ve got in my laptop though (that may not be that easy as the original image that’s still sitting on the old non-SSD drive was also 500GB).

    The other messy part is that you can’t easily develop within a single version of Visual Studio for Windows Phone 7.1, 8 and 8.1. Visual Studio 2012 was the last to support 7.1 and also supported 8.0. Visual Studio 2013 can do 8.0 and 8.1 and Universal Apps (sharing code with desktop Windows).

  • Tour Down Under 2015

    Me and Dad approaching the finish lineYesterday, I took part in the BUPA Challenge Tour ride, part of the 2015 Tour Down Under. I rode with my Dad and Philip – all as part of the Mud, Sweat and Gears bike club. We followed the same route that the professionals would take later in the day. Apparently around 6,500 cyclist took part – some like us doing the full distance, others choosing to do shorter distances by starting at a number of locations along the route.

    The official route started at Glenelg, but to save riding down to Glenelg and then back the same way, we started from the bottom of the Southern Expressway. We then headed south down the Expressway (a route not unfamiliar as the veloway parallels this) and then through Old Noarlunga, back onto Main South Road then past Aldinga to Sellicks Hill.

    Sellicks Hill was designated as the “King of the Mountain” section for the professionals, but it really was just a gentle incline.

    Nangkita food stopFurther along, after nearing Myponga, we veered off back towards Mt Compass. Just before Mt Compass it was great to have my in-laws Rick & Margaret cheering us on (they’re a regular fixture every year to see us during the ride and at the finish line). Passing through Mt Compass, we travelled a few kms before stopping for food and refreshments at Nangkita.

    Back on the bikes, through Ashbourne, Strathalbyn, Macclesfield and then another drink stop at Meadows. No time to stop at the bakery unfortunately!

    Here’s a summary of my ride captured by the Endomondo app on my phone. (Note that the distance/time includes travelling from my home, but I’ve edited out that part from the map).

    We rode a total of 152km and took 7 hours, 4 minutes (including rest stops).

    TDU 2015 Ride Summary

    As you can see, we don’t set a blistering pace 😀 - 20km/h is about our average. Those sharp dips on the bottom graph’s green line correspond to our rest stops. The grey line on that graph shows the elevation.

    I think this year I had one of my better preparations for the ride. I’d been able to get in some regular rides to work and got out most Saturday mornings in the last few months. Whilst glad to finish, I felt in reasonable shape at the end. The weather certainly helped – it was very mild for most of the morning, and we even had a bit of drizzle as we passed through Sellicks Hill. It was only in the last hour and a bit that the clouds parted and the sun made itself felt.

    The tour organisers did a great job. Lots of drink stops and well provisioned food stops. No complaints there.

  • Riding in the wet

    Unlike earlier this week when Adelaide was dealing with 40°C heat and the worst bushfires since Ash Wednesday in 1983, today is wet.

    The weather radar image gives you an idea:

    128 km Adelaide (Buckland Park) Radar - 8th January 2015, 11am

    This is fantastic to help put out the bushfires (and water the garden). Not as much fun if you’re trying to get some exercise for the Tour Down Under ride in a couple of weeks.

    I hadn’t ridden my bike earlier in the week because it had been so hot, so I was determined to ride to work today, even if it was a little moist outside.

    One problem I’ve noticed on the rare occasion that I am out riding in the rain is that your feet get saturated. The water flicks up front wheel and goes straight onto your feet, so you feet end up sloshing around inside your shoes. It’s at those times that you wonder a) why you’re out riding in the rain in the first place, and b) is there anything you could do to make it a little more comfortable.

    This morning I thought I’d try an experiment – putting plastic bags over my bike shoes. The plastic bags were just held on with my reflective strips.

    Long story short.. it worked for about 15min, then I discovered that the other source of moisture in my shoes comes from the rain hitting my legs and trickling down into my socks.

    Maybe sticky tape might have helped a bit. I’ve also heard that you can get proper wet weather booties (apparently made of neoprene like a wetsuit). If you were regularly riding in the wet, I suspect they’d do a much better job.

    At least now I don’t need to wonder anymore.
