There is a way that you can turn off this “feature” when you’re sending links to people: Don’t put the link as the first thing in the message… I use the “.” character to disable this on links that I send. You can (and should) also send a feedback report to Apple asking them to add in a user setting to disable the “feature.”
When I first learned about MongoDB’s geospatial capabilities similar to PostGIS, I was beyond excited because it meant I would not have to write helper functions to find data along geohash borders. Currently my data is indexed by geohash, which has great ordering properties, but is a little unwieldy for the “find me x near y”-type queries.
Unfortunately, it seems as though the 2dsphere index doesn’t cover geoWithin queries. As my collection of geoJSON documents grew from GBs to TBs, I noticed my tools taking extraordinary amounts of time to perform find queries, which caused me to investigate what was happening under the hood.
First, I double-checked that my geospatial index was present:
I was originally going to grant access to all of my Facebook friends (the Raspberry Pi would use Facebook’s API to check who my friends were), but thought that it might be less chaotic to design my own registration system, so that I can easily control when individual users are permitted to enter my room.
Not destroying a UNESCO World Heritage Site
Designing/Printing a container and transmission to adapt a servo motor to the existing door lock.
No existing “Instructables” for this project (or pieces of it therein)
Learning how to make the Arduino talk to the Raspberry Pi
Getting through the University’s draconian firewall to Twilio. (ended up using a few servers as mirrors to get there)
Allowing manual override for maintenance workers who occasionally let themselves in.
Here’s a video I submitted to the Engineering Student Council as part of a contest. (The second half shows how it works)
Update: Some new features!
I’ve been working on a few new features to make my room more intelligent. One of the features will save electricity by turning lights on only when there are people in the room, and turning them off automatically when the visitors leave. Another new feature sends me a text with a picture of the visitor who entered the room. Finally, I’ve created a lockdown mode so that I can go on vacation without worrying about what will happen to my room when I’m out of town for a weekend.
