Building hearing aids with a Linux-based open hardware board

Filed under
Linux

Since Opensource.com first published the story of the GNU/Linux hearing aid research platform in 2010, there has been an explosion in the availability of miniature system boards, including the original BeagleBone in 2011 and the Raspberry Pi in 2012. These ARM processor devices built from cellphone chips differ from the embedded system reference boards of the past—not only by being far less expensive and more widely available—but also because they are powerful enough to run familiar GNU/Linux distributions and desktop applications.

What took a laptop to accomplish in 2010 can now be achieved with a pocket-sized board costing a fraction as much. Because a hearing aid does not need a screen and a small ARM board's power consumption is far less than a typical laptop's, field trials can potentially run all day. Additionally, the system's lower weight is easier for the end user to wear.

Is your startup built on open source? 9 tips for getting started

When I started Gluu in 2009, I had no idea how difficult it would be to start an open source software company. Using the open source development methodology seemed like a good idea, especially for infrastructure software based on protocols defined by open standards. By nature, entrepreneurs are optimistic—we underestimate the difficulty of starting a business. However, Gluu was my fourth business, so I thought I knew what I was in for. But I was in for a surprise! Every business is unique. One of the challenges of serial entrepreneurship is that a truth that was core to the success of a previous business may be incorrect in your next business. Building a business around open source forced me to change my plan. How to find the right team members, how to price our offering, how to market our product—all of these aspects of starting a business (and more) were impacted by the open source mission and required an adjustment from my previous experience. A few years ago, we started to question whether Gluu was pursuing the right business model. The business was growing, but not as fast as we would have liked.

An Everyday Linux User Review Of Elementary OS 5.0 Juno

Elementary OS is currently riding high in the Distrowatch rankings and it has been a while since my last review so I thought it was high time I took another look. The tag line at the top of the Elementary OS website reads as “The fast, open and privacy respecting replacement for Windows and macOS”. In this review I am going to examine this claim in depth as well as other claims such as “Apps you need, without the ones you don’t”. The website states that the applications have been carefully considered to cater for your everyday needs so you can spend more time using your computer and less time cleaning up bloatware. Without further ado lets separate the fact from the fiction and explore Elementary OS with a virtual magnifying glass befitting a well known sleuth. After all it is “Elementary” my dear Watson. (Sorry, couldn’t resist). Read more
