It baffles me they're so casual about it ...
- netgusto 6y agoSee no evil :) There could be non-shady reasons to do this. Besides, I think this statement is just meant to give a sense of the kind of processing that can be done, and the scale it can reach.

- jccooper 6y agoPerhaps you're unfamiliar with the multitude of excercise tracking apps? Tracking is entirely the point of those. https://www.strava.com/ https://www.strava.com/ for example.
- haxen 6y agoThis statement comes from our benchmarking work: https://jet-start.sh/blog/2020/06/09/jdk-gc-benchmarks-part1 https://jet-start.sh/blog/2020/06/09/jdk-gc-benchmarks-part1 The point is that Jet can track several million distinct keys, even on a single machine, and finding velocity vectors boils down to linear regression sliding window against two FP variables. If your concern is why you would specifically want to track locations, the answer is that there are plenty location-based apps that track locations with user's consent.
- jmnicolas 6y agoYes my concern is about how casual you sound about tracking millions of GPS locations. By user consent you mean someone clicked a button without thinking to get to the app ?
- haxen 6y agoHere are some examples where user consent is undisputed: ride hailing, bicycle rental, street navigation, running/biking/sailing contests, location-sensitive searches. These are the kinds of applications for which Hazelcast Jet offers easy scaling into millions of users.
- rswail 6y agoInferring velocity vectors would be very useful for analyzing traffic flows, impacts of lane widening/reducing, signal timing, ML for adaptive traffic management, etc. None of those things are nefarious and don't necessarily provide additional knowledge, as long as care is taken to fully deanonymize and fuzz start/stop/end locations of trips or associate trips together. People agree to provide this information to services like Waze etc for exactly these tasks.
- kgraves 6y agoWhich is still a disgusting and unethical use of technology.
- kittiepryde 6y agoIt could be. It even might be. The baseline expectation, a better traffic forecast, is not good or evil -- but it is a benefit many people want.
- kgraves 6y agoUnfortunately it is under a company known for shutting down products and that spies on you. It is better to use alternatives like Open Street Map, or if there was absolutely no other option, Apple Maps.
- t0mas88 6y agoI use Waze, I'm choosing to give them my driving data to get information on traffic in return. That's not unethical, that's a choice I actively make. Them selling my data to others without telling me is unethical, but that's not the case that Jet describes.
- kgraves 6y agoWould you be interested in giving them your phone number? how about your contacts as well? maybe your own voice? apps have you've installed? and when you're not using the app, keep them posted on your location while you're at it too. > Them selling my data to others without telling me is unethical. Don't you think Google does this to you already?
