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.

At the start of every day, go to amazon and Google and search for lingerie (or appropriate underwear for your gender of choice).

All day long, web pages you visit will be filled with pleasing images.

People are comparing this to packet radio. Well, the first software I used for internet access was ka9q, originally for HAM use. And it ran on DOS. So there's no need to feel left out.

There were some with a full set of calculator keys which included a stylus clipped to the strap.

Also there was the PalmOS Fossil watch (a stylus, but no keyboard).

Only if you don't opt for the airbag or parachute modules.

Just as with the lightning connector, they make a big point that the plug is reversible but NO mention of whether the socket can be used either way around!

And it has versioning via the website. You can see all recent activity, revert to old versions and undo deletions.

And yet won't tell us what they are?

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.

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.)

Well I heard that they track the trains, so they're sure to be tracking buses too.

You may need to use -c to force rsync to compare checksums.

I use something like this as part of my backup DATE=$(date +%C%y%m%d%H%M)
rsync --del --backup --backup-dir=../changedfiles_$DATE

The whole backup also goes to S3 glacier.

As an added step - I don't delete pictures from my camera unless they match the checksum of files in the _backup_ - not the original copy (via a script).

That way, once they're first copied from the camera, a single failure in the original, PC copy or backup copy will all result in the camera version remaining and I can check what has gone wrong.

Google Chrome allows easy creation and switching of user profiles.

I've wondered whether I should have a separate profile for each social site as a way to isolate them.

I turn off 3rd party cookies, but I heard that there was an exclusion for sites that you had logged into and received cookies from.

Meaning, 3rd-party ad site could not send you cookies, but Facebook still could if you'd signed in to it earlier.

More drastic isolation of browser instances is another option (I've wondered about sandboxie but not tried it).
