iPhone Location Tracking

April 20th, 2011

As has been widely reported today, iPhones have been logging location and timestamps in a file that can easily be accessed on the computer the iPhone is backed up to. This doesn’t seem to pose a massive privacy/security issue since the data never appears to leave the user’s iPhone and the computer it is connected to, but it is understandably getting a lot of attention.

Personally, I’m quite pleased this data exists. I’ve been tracking my location with Google Latitude since it was made available with iOS 4 but this seems to provide an easier mechanism to visualise it. Take a look at my movements in the UK since August last year:

Unhabit – a Startup Weekend experience

March 14th, 2011

Last weekend was spent with dozens of technical and business people in Cambridge, all working on creating a new web business from scratch at Startup Weekend Cambridge. Whilst the venue lacked good coffee and good wifi (two essentials for an event of this type), it was a great experience.

The team I joined worked on an idea for how to quit smoking by self imposing financial penalties and asking your friends to report when they spotted you lighting up. I worked on refining the idea, developed the branding, created a promotional video and built a simple iOS app, as well as helping our two developers to get a demo site up and running.

Take a look at our video to get a flavour for the idea. Follow us on twitter. Sign up for notifications on our website and look for more updates on our blog.

Not bad for a weekend’s work. Thanks to Matt, Danny, John and Richard for making a great team.

I’m famous in Norway

February 6th, 2011

Turns out my exciting new Facebook profile picture got featured in the Norwegian newspaper Stavanger Aftenblad on Friday.

What a crazy world. Thanks to Annicka Lundin for letting me know. If anyone wants to send me a physical copy I’d be most grateful.

Video with a DSLR

January 12th, 2011

Since I got my Canon 7D a few months ago, I’ve been interested to try out its video capabilities, which were one of the many improvements over the 400D I had previously.

I shot this with a 50mm f/1.8 lens and got the low angle using the Manfrotto 190XPROB tripod that I recently received. The camera was set up using the custom settings suggested by Tyler Ginter. Thanks to Scruff for being a reasonably cooperative model.

Playing with the new Facebook profile

December 13th, 2010

Inspired by Alexandre Oudin, I updated my new Facebook profile page to extend my picture beyond the usual confines of the top left corner.

Now if only I could take control of my friends’ profile pictures and the adverts, I could make the picture even bigger!

Warning: This is a high maintenance profile picture. I’ve already had my eyes changed to a different colour by an intelligent friend.

King’s Affair 2010

June 20th, 2010

I’ve spent a good chunk of the last year organising the annual King’s Affair at my college in Cambridge. As Chair, I’ve been responsible for the budget of over £85,000 and for coordinating the team of 18 amazing students who all made sure that our 1400 guests had one of the best nights of their lives.

Set up and take down takes about four days in total, and by the time I went to sleep the day after the event I’d been up for well over 40 hours. Here’s my little memory of how it all went:

The Biggest Company in the US?

May 27th, 2010

Now that Apple has surpassed Microsoft to become the second largest company in the US by market cap, the question arises, will it ever become the biggest?

This position is currently held by Exxon Mobil, with a market cap of $278billion to Apple’s $222billion. It certainly isn’t implausible to imagine this happening within the year, given Apple’s strong growth. Assuming Exxon Mobil stays at the same valuation (unlikely, but bear with me…) Apple’s share price would have to jump from it’s current $244 to just over $305. A big jump? Yes. Unrealistic? Perhaps not. The NASDAQ give the 1 year target estimate as $315.

Taking the massive assumption that a year or two from now, Apple becomes the biggest (or should that be most valuable) company in the US. The next question is, how do they justify that position and won’t the stock be grossly overvalued by this point?

Before we go any further, it should be noted that I’m pretty unqualified to talk on the subject, but just wanted to make my thoughts public.

First of all, some reasons why Apple would be too highly valued:

The Steve Jobs question. Whatever you say about the ability of the rest of Apple’s employees, the truth remains that at the point Jobs is no longer CEO, the stock will tank. This high risk is something investors are going to be aware of and is unusual for a company this large.

Does it really make sense? Apple are a niche computer company who have started making quite expensive phones that some people like. Should they be worth more than Walmart, who have 3,500 stores in the US that are visited by almost half of Americans every week! When something seems too good to be true…

Google. The old rival was often seen to be Microsoft, but it is clear this isn’t the case any more. With Android beginning to outsell iPhone, the immediate smartphone dominance by Apple could be quickly eroded by a cheaper, more open platform that is supported by a wide range of manufacturers and carriers. Can iPhone keep up?

Losing the magic. With stories of App Store rejections and suicides at manufacturing plants, not to mention anti-trust and patents, it seems Apple is having to face up to the reality of being a really large company. People don’t see them as the underdogs anymore and are starting to question the control they have over all their products.

And some reasons it is reasonable for Apple to be the largest company in the US:

iPad. I said before the iPad was announced that I thought it could replace laptops for many people and I stand by that even more having owned one for the last month. The iPad has the potential to replace the PC (in the personal computer, including laptop, sense) in many people’s lives. It will take a while for many to move away from a proper computer to a “big iPhone”, but given time I really believe it will happen. Owning the new mainstream computing platform is valuable.

Owning the whole platform is valuable. Apple figured that one out decades ago. How can HP, Dell or Lenovo differentiate themselves when they are all selling Microsoft Windows, and therefore rely on Microsoft to provide their customers with a good experience? HP are starting to realise this, hence the acquisition of Palm, but have a long way to catch up.

Targeting the high end. Whilst the rest of the market race to the bottom with cheaper and cheaper computers (even if you take netbooks out of the equation) Apple stays firm at the premium end. Apple have a 91% share of computers over $1000 sold to consumers. This means profit margins can stay at a healthy 25%, which is when market share stops being so important.

Amongst my peers at university, more and more are choosing to spend their limited funds on a Mac. Because of this, for many (perhaps the majority) of my university friends, their largest ever purchase has been from Apple. Okay, so they’ll buy houses and cars and it won’t seem so big, but the fact is still impressive and shows how technology spending is not something people are scared of.

To conclude: Apple’s stock price has been incredible to watch over the last few years, yet I’m not sure Apple will ever reach the biggest company milestone and I am nervous about the things that could go wrong along the way. Despite this, I think they are well positioned to benefit from greater consumer use of technology and their stock can continue to grow.

Full disclosure: I hold a small, long-term personal position in AAPL.

Student Cooking

May 10th, 2010

Since I’ve had a kitchen in my student accommodation, I’ve ‘cooked’ a meal most days, but often this doesn’t stretch far beyond a cheese toastie or frozen pizza.

Now I’ve nothing to do but revise, I thought I may as well cook myself some decent food. To keep me entertained and to somewhat decrease my intake of crap. The lack of utensils/pans/spices/oils makes everything that bit harder than at home, but I guess I’ll have to cope one day.

Some experiments the last couple of nights:

Tomato and Feta Pastry Tart
Serves 2

Tomato and Feta Tart

Time to prepare: 5 mins
Cooking time: 15 mins

  • Pre-rolled puff pastry
  • Tomato Pesto
  • Feta Cheese
  • Cherry Tomatoes
  • Fresh Basil
  • After remembering to defrost the pastry (the main downside to this meal), spread the pesto, chop and place some tomatoes and crumble some feta. Cook in oven on a normal heat. Remove and serve with ripped basil on top.

    Really simple, and tastes pretty good.

    Caponata

    Caponata

    Slightly more ambitious this time, I tried a proper recipe as opposed to a pile-stuff-on-pastry method.

    Caponata by Yotam Ottolenghi

    Took the best part of an hour, but turned out reasonably well and proved a nice meal served with warm ciabatta.

    Next time, maybe I’ll see if I can branch away from Italian cooking. I’ll find it difficult, believe me. Any suggestions are welcome.

    Initial reactions from playing around with the trial of Photoshop CS5 make the hype worthwhile. One of my many successes reproduced below. This is made from one very loose lasso selection and a press of one button.

    Revision Status

    March 10th, 2010

    So, as my term comes to an end, the focus inevitably shifts to revision. It’s something I struggled to knuckle down to last year, and so I decided to spend yesterday building a web-app to help me track my progress, along with my classmates.

    Welcome revisionstatus.com

    The easiest way to explain what this does, and why it should prove useful, will be through demonstrating it.

    Users log into a primitive user authentication system.

    User login screen

    Once authenticated, they are taken to a list of all the lecture courses in their chosen year and subject. These are manually added, and currently only available for University of Cambridge, Computer Science Tripos Part 1B (Second Year).

    Lecture list

    The orange bars behind some of the lectures show the progress in that subject. This is calculated as an average of the progress of the ‘Course Topics’ that are defined below. As you can see, I have a way to go.

    There is also a view which show the topics aligned next to the questions in the exam, on which they will be examined.

    Exam Paper Questions List

    You can access Course Topics by clicking on any Lecture Course.

    Course Topics list

    These are not as strictly defined by the University, and so I choose which topics I want to split the course into. Additional topics can be added using the box at the bottom of the screen.

    If I click on a topic, I can change my progress or delete the topic.

    Topic view

    You can also see the progress of any ‘Supervision Partners’. I am paired with two people for example here, and so I can see if they are ahead or behind me. Rather than creating a competitive aspect, the idea is to find out who you should ask for help from. If one partner is ‘Feeling Confident’ about a subject that you don’t understand then it may be a good idea to have a chat with them.

    The system is obviously very limited in its scope at the moment, and I only expect three users during this exam period. However it is designed in a way that other degree courses, years etc. could be easily added with little work. Maybe if it works well for me this year then I’ll invest some time in making it more available to others.

    Now, if you’ll excuse me, I think I should do some revision. After all, most of this tracking could have been done in minutes on a sheet of paper…
