Sleep apnea graph
At the start of the pandemic, I read a suggestion from a nurse that having a pulse oximeter would be a good idea. I’ve also had issues sleeping for some years including mild (and some not-so-mild) sleep apnea so I figured it might be good to document these. I bought a model which can be worn comfortably overnight and track the full night’s sleep, the Wellue/ViaTom SleepU P03.
The data it’s shown me is alarming. I have been having apnea events almost every night, some of these lasting long enough to dramatically drop my oxygen saturation. I’d been wondering why I’d suddenly find myself wide awake at 3 AM. Now I know it’s because I’d stopped breathing and my body struggled itself awake.
Though I’ve collected months of graphs showing a problem, I’ve not been successful demonstrating this during the VA sleep studies I’ve had done. I don’t do this every night but it happens with enough frequency that it makes it hard for me to feel rested in the morning. I’m hopeful that a future study will open the door to some treatment. A good night’s sleep is a fantastic gift.
Along my sleep apnea journey, I found the excellent OSCAR app, an open-source data visualization tool that gathers data from CPAP machines and pulse oximeters like mine.
Getting old is not for wusses.
It’s October 6th, day whatever of our home quarantine thanks to the COVID-19 novel coronavirus and President Trump’s utterly abysmal failure to confront it early on. We’ve been essentially holed up since March going out only for essential shopping, medical appointments, takeout or curbside food, and little else. My company shuttered its downtown Raleigh office in favor of an everyone-work-from-home model. I haven’t hugged my mom or dad in over seven months.
We do get out for exercise every weekend possible. Kelly and I have put a few hundred miles on our bikes riding the greenways. But I still won’t go into an office building or an enclosed space for any longer than necessary.
We’ve learned so much about COVID-19 since those early days. Poorly-ventilated spaces are the worst, particularly if they’re crowded. Outdoor activity is safest. Experts roll their eyes at the photos of people at beaches used to illustrate pandemic news stories, as those scenarios are among the safest.
As I’ve written before, I kept noticing ads pop up on Facebook and Twitter which seemed suspiciously as if they were triggered by conversations held around my phone. I got so fed up with this this summer that I briefly listed my Samsung Galaxy phone on Craigslist. And yet, something pulled me back. A friend pointed out that certain apps – even system ones – could be removed from the phone without actually rooting it. I have always been impressed with the Galaxy’s hardware; it was Samsung’s bloatware that drew my suspicion. Samsung’s locked my phone down so tightly that rooting it is out of the question. Perhaps this other method might work?
After carefully examining apps in Android’s app permissions page, paying particular attention to system apps (which usually are firmly entrenched and can’t be removed), my eyes focused on one quite innoculous one that called itself SmartThings.
I already tweeted my discovery of two separate SmartThings apps, each with wildly different permissions, but a search of the phone’s packages never turned up any of the more entrenched, system version of SmartThings.
After more Googling, I found the name of the offender, a mysterious package called com.samsung.android.beaconmanager.
