I find Dolphin streets ahead of any of the competition (at least, when I last tried using any of them). The ability to have both a command line and a graphical view of a directory in the same window, so I can seamlessly switch between GUI and shell, is something I consider a fundamental requirement of a modern file browser. I get thumbnail views of image files and documents for quick identification, and I can easily run script commands against them. If I change directory (either by clicking in the GUI half, or by running cd), both views change.

As far as I'm aware, no other file browser does that.

I hardly use my phone to make phone calls or texts, less than 15 minutes a month and an average of zero texts. I deliberately chose a plan with minimal minutes (about 200 I think) to save a few quid. The default tends to be unlimited though.

No. It's one of the missing features they haven't added to Google Photos yet. You can see locations for photos already geotagged, but you can't add a geotag to a photo that doesn't have the information, or edit geotag information on a photo that does. I still go to picasaweb for this feature.

I've raised a feature request for this, but it's still missing the functionality.

I'd say 15, so if an author becomes widely popular and Hollywood want to try to cash in on that by making a film of their books whilst they're still fresh in the public's mind, then at least the author gets a chance to make a profit from the films.

Our business cards have a QR code on the back. If you want an old style business card, we can give you one. If you want to just stick our contact details into your phone, then just turn the card over and scan the code. I could also display the QR code on my phone, but I'd rather pass a bit of disposable cardboard around a group of strangers than my phone.

I'm also bad at remembering names and faces, so if I've just been given some cards at the start of a meeting, I can drop them in front of me and glance at them to recall who is who.

Oh, I have :-) Back in the days when we used C, someone had something like:

if (foo)
      A_MACRO

It worked fine, until the #define was changed to consist of multiple statements. The problems caused weren't local to that bit of the code, so it took ages to track down.

I've seen a number of easy to fix bugs caused by this as well, but none quite as spectacular as the above.

Problem with tabs is when you're lining up code on multiple lines (e.g., variables, where many people use whitespace between the type definition and the name to line up the names), a different tab size breaks the alignment. You either have to force everyone to use the same tab size, or suffer ugly code.

If you're aiming to keep line length down (back in the days of 80 character displays), switching between tab sizes could cause code to become an unreadable wrapped mess if it'd been written using 2 space tabs (and fitted nicely into the editor window) and you viewed it with 8 space tabs (at which point it no longer did).

These days it's almost irrelevant. Most IDEs allow you to reformat the whole file with a single keypress to whatever style you want. Then reformat back to project standard before submitting to source control.
