Around this time of year it’s great to have a festive tipple such as Bucks Fizz, Mulled Wine or Mulled Cider. I’ve started making my own Mulled Cider recently as it’s made from fairly common spices.
Ingredients
4 cans of cider (Scrumpy recommended)
Spices: 6 cloves, 3 star anise, ¼ nutmeg (finely grated), 1 cinnamon stick, 1 vanilla pod (halved, or ½ teaspoon of vanilla extract)
Add the cider to a large pan. Heat it on low heat for 3 minutes.
Add the spices and the juice of each fruit.
Then crank up the heat to boiling. Once boiling turn the heat down and simmer for 6 minutes.
Grab a spoon and take a taste of your wonderful concoction. It probably needs sugar. Add two tablespoons of sugar at a time until you get a good balance of sweet and spicy.
Once the sugar is mixed you can enjoy your creation immediately. Grab a ladle and put it into a mug or glass.
Last Saturday I attended the Developer Developer Developer Scotland 2011 conference in Glasgow. I posted before about the sessions I’d planned to attend, which I ended up ignoring.
The event itself was exceptionally well run, timing was like clockwork and you didn’t see anyone running around trying to find the right video adapter for their laptop. It’s incredible that such a well run event can also be free. The only minor problem was the lack of air conditioning, which meant enduring a tropical climate for popular sessions.
Personally I haven’t had to code for .NET for anything serious since 2007, so I’m not overly keen on attending sessions on ASP.NET or about the latest library being reproduced for c# programmers. This has proved tricky at previous DDD conferences I’ve attended where you have no choice but to attend a .NET based session. Thankfully this conference proved to accommodate with sessions where the programming language wasn’t important.
I started the day off at an open discussion event hosted by Craig Nicol on “Professional Development”. There were only a few of us at the session but it was a wonderful way to wake up at 9am while discussing what we all considered traits of a professional developer. Craig guided the session by using a mind map already containing the BCS definition of professional development. Colouful anecdotes were retold by the session attendees and it was good to hear about the working environments of others.
Feeling inspired, I then headed along to Gary Short’s presentation on “Asymptotics and Algorithms”. Gary himself was part of an ongoing Twitter drive-by that ended up with a satirical twitter profile being created in his honour. Not that I want to feed inflated egos’ but this session was brilliantly done. Gary clearly knew his stuff and had that knack of taking something complicated and making it simple to understand.
After lunch I attend the BDD with F# session. I was under the impression that F# was similar to Clojure, but I couldn’t of been more wrong; there wasn’t a single piece of parenthesis in the entire talk!
The final session for me was Chris McDermott’s introduction to Kanban development. In the session Chris went over the important parts of Kanban and then discussed how he could have used the methodologies practices in his past. The idea of evolutionary change over time, rather than using a change everything approach is very compelling. I’ll keep this talk in mind next time I have to introduce an agile change in an organisation.
I met up with Chris, Rob Lally and a few others at Thai Lemon Grass for a post conference meal. The meal like the conference was excellent. I can’t thank the Scottish Developer community enough for making this day happen.
This saturday the Scottish Developers are treating us to their annual free conference in Glasgow: Developer Developer Developer Scotland 2011 (#dddscot for short).
There’s 6 tracks on this year which were voted on in a free vote, and there’s still a strong .NET theme. Here’s the sessions I’m planning on attending.
I’m just back from attending an Alex Bellos event as part of the Aye Write festival. Alex has spent the last few years traveling the world exploring how different cultures approach mathematics.
The talk covered an eclectic mix of topics ranging from the mathematical reasons for Puff Daddy becoming P Diddy to pre-electronic calculators designed to be used in rally cars.
I’m going to talk about the three parts of his talk that I found most interesting.
Tallying systems
Tally marks are a form of numeral used for counting. They allow updating written intermediate results without erasing or discarding anything written down. The system Europeans are used to seeing is the 4 single 1s with a strike to represent a 5.
This system is pretty simple and often used:
However, in South America they use a system where you build a box:
And in China they use the 5 lines that make up the parts of their number 5:
I’m going to switch to using the the South American system!
Japanese Abacus counting system
Alex also showed a video of some Japanese kids who excel at adding numbers together. They are using an abacus system in their mind which makes counting a visual rather than an arithmetic problem.
In this video the participants are playing a game called “Flash Anzan” where they have to add up numbers that are being momentarily displayed on a screen without the use of paper.
As if that wasn’t scary enough, the abacus system doesn’t use the part of the brain which we traditionally use for counting, meaning that we are free to use it to perform word games.
In this video the 10 year old girls are counting the numbers displayed to them while simultaneously performing a word game where you have to start a word with the last syllable used by the previous word.
Chimpanzee Math
During the 1980s (in Japan again) they trained a few Chimpanzees to be able to recognise the numbers 1 to 9 and be able to answer questions about which one is higher and lower.
Then they decided to see if the chimps could remember sequences shown to them for a short period of time and then use a touch screen to select the numbers in order after they have disappeared. The scientists were suprised to see find that the chimps could perform to the same levels as humans in a control group.
Then they thought it would be interesting to reduce the time the numbers are shown from 0.6 seconds to 0.4. The human group only managed a 50% success ratio when shown the test. The chimps still managed 100%. Amazingly, they were able to reduce the time to 0.09 seconds and the chimps still have a 100% success rate.
In March the Aye Write book festival will be bringing authors from around the world to Glasgow’s Mitchell Library. The annual festival started in 2007 and this year has a special focus on science and technology.
Here are the events for which I’ve bought tickets so far…
I’m one of many Joe Wright’s and I currently dwell in Glasgow, Scotland. I work as a software developer for JPMorgan and previously the Scottish Qualifications Authority. I mainly use Ruby, Java, Bash and anyautomationtools I can get my hands on.
As well as this blog I now have a technical blog: Joejag Tech
I used to be heavily into Gentoo Linux but since finishing my Bachelors and Masters in Computing at the University of Aberdeen I haven't found the time. I can usually be found hacking on side projects, writing songs on guitar or enjoying a fine Islay single malt. I'm happy to say this fascination has now manifested as a Single Malt Guide
