For Christmas my wife and I brought each other a new FitBit One device (Amazon affiliate link included). These are small fitness tracking devices that monitor the number of steps you take, how high you climb and how well you sleep. They’re great for providing motivation to walk that extra bit further, or to take the stairs rather than the lift.
I’ve only had the device for less than a week, but already I’m feeling the benefit of the gamification on FitBit.com. As well as monitoring your fitness it also provides you with goals, achievements and competitions against your friends. The big advantage of the FitBit One over the previous models is that it syncs to recent iPhones, iPads, as well as some Android phones. This means that your computer doesn’t need to be on, and often it will sync without you having to do anything. In the worst case you just have to open the FitBit app to update your stats on the website. Battery life seems good, at about a week.
The FitBit apps sync your data directly to FitBit.com, which is great for seeing your progress quickly. They also provide an API for developers to provide interesting ways to process the data captured by the FitBit device. One glaring omission from the API is any way to get access to the minute by minute data. For a fee of $50 per year you can become a Premium member which allows you do to a CSV export of the raw data. Holding the data, collected by a user hostage is deeply suspect and FitBit should be ashamed of themselves for making this a paid for feature. I have no problem with the rest of the features in the Premium subscription being paid for, but your own raw data should be freely available.
The FitBit API does have the ability to give you the intraday data, but this is not part of the open API and instead is part of the ‘Partner API’. This does not require payment, but you do need to explain to FitBit why you need access to this API call and what you intend to do with it. I do not believe that they would give you access if your goal was to provide a free alternative to the Premium export function.
So, has the free software community provided a solution? A quick search revealed that the GitHub user Wadey had created a library that uses the urls used by the graphs on the FitBit website to extract the intraday data. Unfortunately the library hadn’t been updated in the last three years and a change to the FitBit website had broken it.
Fortunately the changes required to make it work are relatively straightforward, so a fixed version of the library is now available as andrewjw/python-fitbit. The old version of the library relied on you logging into to FitBit.com and extracting some values from the cookies. Instead I take your email address and password and fake a request to the log in page. This captures all of the cookies that are set, and will only break if the log in form elements change.
Another change I made was to extend the example dump.py script. The previous version just dumped the previous day’s values, which is not useful if you want to extract your entire history. In my new version it exports data for every day that you’ve been using your FitBit. It also incrementally updates your data dump if you run it irregularly.
If you’re using Windows you’ll need both Python and Git installed. Once you’ve done that check out my repository at github.com/andrewjw/python-fitbit. Lastly, in the newly checked out directory run python examples/dump.py <email> <password> <dump directory>.
Alan Wake is a survival horror game where you’re fighting off hordes of people possessed by darkness. L.A. Noire is a detective story that has you solving crimes in 1940s Los Angeles. Both feature an over the shoulder third person camera, and both have excellent graphics. They also both have a film like quality to the story. In Alan Wake the action is divided up in six tv style “episodes”, with a title sequence between each one. It also has a number of cut scenes and narration by the title character sprinkled throughout the game which help to drive the story forward.
In L.A. Noire you are detective try to solve crimes and rise up the ranks of the police force. The game features cut scenes to introduce and close each case. During each case you head from location to location and interviewing suspects and witnesses. The big breakthrough in L.A. Noire is the facial animation in the game. Rather than being animated by hand the faces of characters were recorded directly from actor’s faces. This gives the faces a lifelike quality that has not been seen in games before.
This recent surge in isometric real-time games was caused partly by Zynga’s incredible ability to “keep the positive things and get rid of the negative things” in this particular genre of games, and partly by a shift in consumer interests. They took away the frustration of figuring out why no one was “moving to your city” (in the case of SimCity) and replaced it with adding friends to be your growing neighbours.
The need for the face of characters in L. A. Noire to be recorded from real actors limits one of the best things about games: their dynamic nature. Even if you get every question wrong you still solve the case and make progress. Initially you don’t really notice this, but quickly I found it meant that the questioning, the key game mechanic, became superfluous.
Alan Wake is a fairly standard game in that there’s really only one way to progress. This is well disguised though so you don’t notice. The atmosphere in the game forces you to keep moving and the story progresses at quite a pace.
Ultimately it’s not for me to criticise what games people want to play. FarmVille and the rest of Zynga’s games are enormously popular. What disappoints me most about L.A. Noire is that it such a technically advanced game, but falls down on such a simple piece of game mechanics. Alan Wake on the other hand succeeds mostly based on story and atmosphere, and that’s the way it should be.
