Security Medium — Strava Heatmaps have Unintended Consequences
The popular exercise tracking app Strava regularly produces a really cool heat-map that shows where most people run, cycle, swim etc.. The data is anonymised, so it all seems like some innocent fun. The latest version of the heatmap was published back in November, and no one thought it was a problem.
This week’s Dumb Question comes from David Bodgan from Japan. He wrote:
“When I send jpeg pix to my siblings, they give me all sorts of grief about not being able to open them up. I guess they only show up as thumbnails.
The funny thing is that in their replies to me, I get the full jpegs back that I sent to them. Also funnier, the same pictures came out fine on my Mom’s Android tablet.
I’ve been trying to figure out what is going on, but haven’t come up with anything.”
This is one of those problems that probably has no good answer. We could spend a lot of time figuring out what kind of computers and phones they’re on, what mail program they’re using and try to diagnose it on their end. That would take a lot of time and energy. How about if we solve the problem differently?
Allister here standing in for Allison this week. I’ll tell you how I solved my OS X network drive problems. Then Dorothy, aka MacLurker, reviews the iOS game Enigmo. Next, inspired by Allison, I encourage you to play with fire. We hear from Drobo about their new myDrobo and DroboAccess services from the NAB conference. And finally, I review the Beurer GS485 digital scale.
Allister here, taking my turn to stand in for the vacationing Allison.
I’m a huge supporter of the OS X operating system and often try to gently drop hints to those second class citizens we call Windows users about how great we have it. But in the interests of objectivity, I do always admit there are flaws. One of the biggest flaws I warn people about is how OS X handles network volumes. That is, drives on another Mac, connected to a router like an Airport Extreme, or on a dedicated Network Attached Storage, or NAS, device.
I’m not a chef and I won’t even suggest that I’m an accomplished cook. In fact, it’s well known that Steve and I have been eating on a repetitive schedule for going on 20 years. Our kids first pointed it out when they noticed that we had made burritos every Monday for a very long time. It has been suggested that this is what happens when two engineers marry.
Like most kids, when our daughter Lindsay moved out on her own, she rebelled against her rigid upbringing and decided to try to cook two new meals every single week. She has inspired me over time, sending me the easier recipes in a quest to get me to break out and experiment.
