AWS Update

Monday, May 5th, 2014

At the end of April I went to the AWS Summit at ExCeL London, partly to keep up with the competition but largely because the attendees are a different crowd to those you get at your average IBM conference. I managed to miss most of the keynote, partly by design (no early start and an off-peak ticket) and partly due to someone driving in to a level-crossing in Southampton! Having watched the video subsequently, I don’t think I missed a great deal. The only announcements from Amazon that peaked my interest was the arrival of Amazon WorkSpaces in Ireland and the availability of the Twitter stream in Amazon Kinesis.

As in common with the rest of the day, it was the customer slots that were the most interesting. For example, SwiftKey talked about their use of Hadoop on AWS to crunch Wikipedia in other languages to build a starter set for their language models, through to CloudFront as the CDN for serving the final models up to their customers.

I had an interesting chat over lunch with someone who was actually an IBM customer and then wandered the expo watching demos by some of the likely suspects in the cloud deployment, management and monitoring space (Chef, Splunk, DataDog, …).

After lunch the breakout sessions began with six parallel tracks this year. I went to Deployment Done Right first, covering Elastic Beanstalk, OpsWorks and CloudFormation. The only new news for me was an aside that Beanstalk nows supports Docker. It seems like pretty lame support for containerisation though as you appear to get an EC2 instance per image. The accompanying presentation from Sportpursuit.com was most notable for the long list of open source software in use (Nginx, PHP, Magento, Varnish, Redis, Memcached, Elasticsearch, Jenkins, Capistrano, Capify EC2, Boto, …).

Next up was Dynamic Content Acceleration covering the CloudFront CDN and Route 53 DNS with the aim of knocking a second off your response times. The customer this time was import.io which is an interesting site in its own right, providing the capability to turn websites in to structured data (for free).

For the last session of the day I picked Scaling on AWS for the First 10 Million Users which did not, as you might expect, spend a lot of time on auto-scaling, but covered all aspect of application architecture that would contribute to scaling. The customer was the mobile taxi app firm Hailo who are pursuing a micro-services architecture. They are using containerisation (they didn’t specify which) and are apparently writing their own controller to manage the distribution of those containers across EC2 instances to balance workload.

The Vyne

Saturday, May 3rd, 2014

The VyneFor the second time this year we headed over to the National Trust’s Vyne Estate just the other side of Basingstoke to meet up with friends. As on our previous trip we were treated to lots of sunshine although there was a bit of a nip in the air for the first half of the day. There is plenty to keep the kids amused whether it is the sculptures scattered around the grounds, relaxing on deck chairs on the lawn, counting (toy) rats in the rooms of the house, the bird hide, or the imaginative playground. This time we also wandered a bit further in to the woods and enjoyed the bluebells and building dens.

Synchronised training

Friday, May 2nd, 2014

For the past couple of years, uploading my running training has been a bit of a faff. I like to use a desktop app (SportTracks) so that, whatever the changing fads online, I still have all of my data in one place. (It goes back to 2006 when I first got my Forerunner 305. Some day I may even important my old Polar Training Software data.) The desktop app also has some interesting plugins. One of these I used to push my training to dailymile for comparison with a few friends and colleagues and for the widget on this site. However, I’m also partial to a bit of segment stealing on Strava. Sadly no simple SportTracks plugin for Strava so that was a separate upload.

After a bit of search and experimentation, my new workflow is to upload to the SportTracks website which then syncs seamlessly (in both directions) to the desktop app. Then I’m using the excellent online tool Tapiriik to automatically synchronise the data from SportTracks to Strava.

On the plus side, this means I’m now only downloading once and it doesn’t have to be on the machine with SportTracks installed. Also, without really thinking about it, it means I know have 8 years worth of data synced back to Strava!

On the negative side, Tapiriik doesn’t support dailymile so that will have to go by the wayside, at least for now. That means you’ll see a slightly squished Strava widget in the sidebar of this site. The other major downside is cost. The SportTracks site has an annual subscription of $35. Whilst the site is nice and they are continually adding good features, if it weren’t for the sync with the desktop app I wouldn’t be forking out that money. We’ll see how things are going come renewal time. Automatic sync on Tapiriik also comes at a cost but a mere $2 pa for what is a very slick site and available as open source if you really wanted to host it yourself.

Now I just need to decide whether to add Garmin Uploader to my shopping list so that I don’t even need to turn on the Mac! (Works with my Nexus 7 but not my S2 unfortunately.)

Brecons JK

Wednesday, April 23rd, 2014

Emma CyclingThe second week of the Easter holidays we were booked in to a lovely cottage (once we found it!) called Heartsease near Brecon. We’d brought our bikes but I’d managed to forget the Trailgator for towing Duncan. Rather than cycling up to the waterfalls above Talybont as planned, we drove up, went for a walk, and then Christine and Emma cycled down to the dam where Duncan and I met them again (Duncan having practiced his cycling back and forth on the dam.)

Pen Y FanThe next day we repeated the walk we did two years ago up Pen y Fan. The main difference this time was that Duncan had to use his own leg power to get up to the summit! Both children were very good and it was only towards the very end of the walk that they both started to grumble a bit as they got tired.

On the third day of the holiday we were joined by Christine’s parents (in the nearby Pencelli Castle campsite) and they took the children to Dan-yr-Ogof caves leaving Christine and I to do another ascent of Pen y Fan, this time walking from near our cottage and taking in Fan y Big and Cribyn as well. The following day we all headed over to Cardiff and had a lovely time with Christine’s brother and family.

Then the serious business started – the JK. The Friday was a sprint race around Swansea University. I had a reasonable run finishing 8th on M35 in what was not a particularly tricky area whilst Christine picked up a Silver medal on her course. After a quick trip to the fun fair we then rushed back to the cottage to cook a big dinner with Christine’s cousin and family having arrived to stay in the cottage next door.

Saturday’s event was on Merthyr Common. It’s not my sort of area as I can neither run nor navigate fast in that terrain. I was therefore pleased with a 6th place in what would have looked like a respectable time if Duncan Archer hadn’t come and beaten the rest of the field by 10 minutes! On Sunday we returned to the same assembly area but the weather which, until this point had been very kind to us, had turned. I not only carried the mandatory cagoule but wore it all the way round my course! I finished 7th in a similar time to the previous day which brought me up to 5th over the two days. Christine failed to make it three second places in a row and dropped down to 4th.

We had to move out of our cottage by this point and went to stay with Christine’s parents in Monmouth. This meant we could leave the children there on the Monday whilst Christine and I went to the (sunny once more) relays at Pwll Du. I ran the last leg in the JK Trophy bringing the SOC team home in a respectable 17th place. Christine managed another 2nd (on first leg in W120+) although her team ended up 5th. Now we just needed a holiday to recover!

Logsearch & Decker

Friday, April 4th, 2014

Yesterday evening I headed up to the London PaaS User Group meeting as there were two Cloud Foundry related sessions on the agenda. First up was David Laing talking about the open source Logsearch project, a bosh deploy of an Elastic search ELK log analysis cluster. His employer (City Index) has this hooked up to Cloud Foundry system logs and, in some cases, they’re also using it for analysis of application logs with addition parsers. They’re looking for people to get involved in the project and help with the next phase: anomaly detection. One major hole in the solution as it currently stands: it’s only suitable for private PaaS as their is no access control over the logged data.

Up second was an entertaining pitch by Colin Humphreys, Founder and CEO of ours hosts CloudCredo, on how to sell hats to monkeys. That was the back story anyway, it was actually about how there is space in the stack for something that gives you the flexibility of IaaS over what you run but the simplicity of management, scaling and load balancing of PaaS. That something is Container as a Service. Specifically, the ability to push Docker files to Cloud Foundry using a custom stack for the DEA. Something that Colin is referring to as Decker.

Colin gave a nice demo but it is obviously still early days. Currently you can only push Docker files not images. There is also no staging at the moment – the image is created when each instance starts – consequently it is not taking any advantage of intermediate images. There is obviously lots of scope for improvement and it’s definitely one to watch. It was also interesting that Colin is currently focussing on the Docker side with the DEA interactions set to change with the introduction of Diego. The project is open source but Colin recommended waiting until he writes some docs before you try picking it up!

Gerry’s 60th

Friday, December 27th, 2013

Birthday CakeAs usual, the final countdown to Christmas began with Christine’s Dad’s birthday. This year was a bit different though as he’d reached a round 60 and a party was planned! Unfortunately the weather was a little unkind as the day was meant to begin with various outdoor activities. Ian and I joined a small party running the route of the Kymin Fell Race in the wind-blown rain. Gerry was injured so had planned a walk but strangely, no-one was keen to join him. Not to be deterred, he walked up the Kymin on his own! The children had perhaps the most sensible idea, getting wet in the swimming pool instead.

Gerry @ 60There was just time to wash off the mud before heading to their local where we were joined by friends, family, neighbours and fellow runners for food and drink. There was a skittles alley laid out down the middle of the room but this remained largely the domain of the children (even when there were other people standing on it!). Following the cutting of the cake (baked by Christine and decorated with the aid of myself and Sarah) Gerry was rendered speechless, although hard to say whether this was due to emotion or Sue stepping in very quickly! Anyway, here’s to the next 10!

King Duncan

Thursday, December 19th, 2013

wpid-king-duncan.jpgDuncan graduated from cow to king this week at his playgroup nativity play. Once again, he looked rather like he was slightly bemused by the whole affair but joined in with all the singing and actions and did rather seem to like his outfit! Then there was Emma’s Christmas lunch, both children had Christmas parties at playgroup and school respectively, and then there was the school carol concert. We’ll all be looking forward to a break come the end of term!

Run some Pubs

Sunday, December 15th, 2013

Today was the traditional ‘Run the Pubs’ where we run round the pubs that we’ve visited on Tuesday evening runs during the summer. There were six of us this year and, in keeping with last year’s tradition, we decided to bin one of the pubs (the Drift at Beaulieu Road Station) for a shorter run (13 miles) starting at the Redshoot Inn and ending with some great food at The Oak at Bank (where Andy somehow managed to book a table with less than a week’s notice). The weather deteriorated on our way round but no-one seemed to mind. We even got cheered along by a selection of Santas at one point when we accidentally came across the route of the CC6 cross-country race (over-taking the back marker in the process!). We also bumped in to Tuesday night veteran Mike Yeo at the New Forest Inn who, clad in wellies, declined to join us for the final short leg to Bank.
