Linux and ARM

With more ARM based devices in the market, and with them getting more powerful every day, it is more common to see more of ARM images for your favorite Linux distribution. Of them, Debian has become the default choice for individuals and companies to base their work on. It must have to do with Debian’s long history of trying to support many more architectures than the rest of the distributions. Debian also tends to have a much wider user/developer mindshare even though it does not have a direct backing from any of the big Linux distribution companies.

I own a Fitbit Surge. But Fitibit chose to remain exclusive in terms of interoperability. Which means to make any sense out of the data that the watch gathers, you need to stick with what Fitbit mandates. Fair enough in today’s trends. It also is part of their business model to restrict useful aspects of the report to **Premium Membership. **Again, fair enough in today’s business' trends.

But a nice human chose to write a bridge; to extract Fitbit data and feed into Google Fit. The project is written in Python, so you can get it to work on most common computer platforms. I never bothered to package this tool for Debian, because I never was sure when I’d throw away the Fitbit. But until that happens, I decided to use the tool to sync my data to Google Fit. Which led me to requirements.txt

A couple of us DDs met here on the weekend. It is always a fun time, being part of these meetings. We talked briefly about the status of Cross Compilation in Debian, on the tools that simplify the process.

Next we touched upon licensing, discussing the benefits of particular licenses (BSD, Apache, GPL) from the point of view of the consumer. The consumer being an individual just wanting to use/improve software, to a consumer who’s building a (free / non-free) product on top of it. I think the overall conclusion was that there are 2 major licenses at a high level: Ones those allow you take the code and not give back, and the others which allow you to take code only if you are ready to share the enhancements back and forward.
