Interesting article about how people diagnosed with Type 1 diabetes have resorted to using outdated hardware and some cracked software to get their insulin pumps to work "as intended" to allow them the freedom to live.

Most people living with Type 1 diabetes have to plan their whole day in advance, or be ready to mathematically calculate if the extra steps they took or the extra bite of cake will throw their blood sugar levels off, or even be awoken in the middle of the night when their blood sugar is too low from not calculating correctly.
So hackers realized that an old model insulin pump had a flaw that allowed it to be hacked, which lead to the hackers realizing that the pump can adjust insulin levels on the fly if it's given the proper data. And since some Type 1 patients have glucose monitors under their skin, all that was needed was an interface to take the realtime readings and convert it to data for the pump to adjust the levels in real-time.
Also shows what's wrong with the Pharmaceutical industry with their insistence to not adapt a system like this by now.
