top Google Announces Image Recognition Advance
findimagedupes builds a database of fingerprints (basically a scaled-down monochrome image) and can call an external program with the matching duplicates. You could read the resolution in the external script using jhead or exiftool.
top Researchers Develop $60 Sonar Watch To Aid the Visually Impaired
Yes, I first heard of similar devices decades ago. Back in the 70s, I think, there were handheld units and I remember seeing a sonar system built into spectacle frames (I don't know if it was a practical design, not sure how it was powered).
I think that the story here is that it's cheap and built into a watch, although I'd have thought that a handheld device would still be better for aiming as well as battery life.

top Charity Promotes Covert Surveillance App For Suicide Prevention
It depends on how the app works.
Does it work like an old-style program that performs some computation and does something, or is it a 'cloud'-based app, i.e. it sends all the raw data off to some server somewhere?
Given that it is said to send an email instead of just display a notification, I suspect the latter, in which case you're sending those potentially 'followers only' tweets off to a third party.
top We Need Distributed Social Networks More Than Ello
I could totally see it being coupled with email accounts
Yes, if either via a separate program or as part of an existing service, everyone had a personal mailing list, the 'social network' aspects would be separated from the transportation method. You would 'follow' someone by sending them a subscribe message (or your app would do it when you clicked a button).
A reader could display a digest of all such mails from the people you follow (maybe sorted by tags added to headers).
Someone without any specialized program could still subscribe and get your mails. Conversely a webmail service like GMail could dress it up to look G+, where someone replying to one of your messages would appear as 'posting on your page'.
The initial draw of a social network is the ease of broadcasting your (possibly inane) thoughts to everyone who wants to hear from you. You don't do that to everyone in your contact list because they've not signed up to know what you had for breakfast. A way of collecting a willing audience is all that's needed.
top BitTorrent Performance Test: Sync Is Faster Than Google Drive, OneDrive, Dropbox
And all the others were uploading an online copy too, so this isn't a like-for-like comparison (I think that DropBox, at least, supports direct local network copying but would probably be making the online backup at the same time).
top Google Announces Inbox, a New Take On Email Organization
It wasn't threading, it was displaying a thread as one scrollable page that was the innovation. I'd not seen a newsreader or mail client that did that before. Combined with collapsing of quoted text (which was an old idea, I think it was in Eudora or Xnews or something, at least), it's an easier way to read through a thread, removing one level of navigation (paging through messages merged with scrolling down a single message).

top Google Foresees Ads On Your Refrigerator, Thermostat, and Glasses
Garmin GPS units have been showing ads for years. It used to be a small message on the search screen or something, but I read that the newer ones display on the screen when they sense that you're stopped (e.g. at lights). So when upgrading I switched to another brand, despite being a fan or Garmin.

top Facebook Estimates Around 10% of Accounts Are Fake
due to FB's policies, legitimate users feel compelled to put in fake names, birthdates, locations, schools, employers, etc.
Or in fact not put most of those in at all. Facebook is still trying to guess which continent I live on (it occasionally asks if I live in cities related to my friends list). I haven't given any info about education, work or interests (although I'm sure there's a big profile on what interests me based on what I click on).

What are you doing? Maybe it it different for some models, but for mine, you place the end of the canister into a trash bag and pull the trigger on the handle. You can even close the base again by pushing it while it's still in the trash bag.
top Does Anyone Make a Photo De-Duplicator For Linux? Something That Reads EXIF?
I've used findimagedups. IIRC, it rescales each image to a standard size (64x64 or something) then filters and normalizes it down to a 1-bit-depth image.
It then builds a database of these 'hashes'/'signatures' and can output a list of files that have a threshold of bits in common. That's how it can ignore small changes, it loses most detail and then can ignore a threshold of differences.
It would fail if an image was cropped or rotated, for instance. It could handle picture orientation it it was modified to store 4 versions of the signature, I guess.
It won't actually remove images itself (I wrote a script to read it's output and delete listed images matching a specific path).
I needed it because Dropbox was 'fixing' orientation when it uploaded images and I wanted to clear out ones I'd backed up directly from the camera. (I usually delete duplicate images based on hash.)
