I don't really know anything about (semi-)professional photography, but I always assumed objectives from different manufacturers were compatible. Can't you use your old glass with the new, different camera?

Just as a bit of additional background modern lenses and flashes may do a bit more than you'd imagine. I'm a Canon user but say I attach a 70-200 zoom lens the auto-focus motor is in the lens so if say tracking a moving vehicle in servo mode there's a constant stream of information flowing between the camera and lens to try and hold it in focus. The current focal length also gets reported back as I zoom in and out, and if a compatible flash is attached it will mechanically move reflectors to direct the most flash power into a smaller area that will still cover the scene.

Those are proprietory protocols but have been reverse-engineered by 3rd party lens manufacturers. Occasionally though the OEM will begin using some new feature / protocol that was always present in their lenses and it's not uncommon to hear that a 3rd party lens needs to go back to the factory for a firmware update to work with a newly released camera.

Not sure really, understanding an article written by an anthropologist on programming seems harder than kernel development to me. But you're probably on the right track though. Other requirements from what I gather are a one-click install and a Microsoft Bob equivalent to ask what you want to achieve.

However, if I *did* see surveillance cameras around here, I'd just continue to go about my business as usual, because I'd be pretty sure nothing I was planning on doing is the sort of thing they're looking for, anyway

We must be a step ahead here in Australia. Only last night I was watching a current affairs program that showed a frame used from 'security' footage used by a local council to book a lady for illegal parking. Only problem was she was clearly in the car, brake lights were on and she had merely stopped on a bend because of traffic congestion. It wasn't blocking an intersection and there was nothing she could have legally done at that point to avoid the situation because of the lane markings.

+ - Ask Slashdot: Best geek toys for goldfish

Submitted by commlinx
commlinx (1068272) writes "As it approaches Christmas I'm in the process of adding a geek touch to my goldfish tank and need some ideas from the Slashdot community. So far I have collected a few static plastic models, such as the Enterprise NCC-1701, R2D2 and a Supreme Dalek to glue to the bottom of the tank; however I would also like to add some more dynamic items. I already have a USB controlled switchable power socket connected to a Raspberry Pi to control the main tank light remotely and was thinking this might be expanded to control some LEDs, motors and maybe even some Nixie tubes. However I'm unsure of the best way to interface these together and also wondering what precautions are needed because the water in the tank may not be pure? I look forward to hearing ideas from the community and am interested in how you would approach the problem."

Thanks for the clarification. I'd assumed from TFS it was GPS data.

It probably makes the anecdote suspect as well unless he's a good cheater but poor liar. I assume the sort of people who buy these products are the kind who might have trouble sleeping and end up doing a little excercise or go for a jog in the early hours.

I tried that too using Melbourne and Sydney and got similar results, but then realised it was because I was using 3000 and 2000 postcodes which are the CBD areas that probably don't have a lot of residents comparitively. Using my actual suburb which is only medium size and is Tasmania yielded 63 results and that would strike me as fairly plausible.

Results are pretty useless in a lot of areas though because of the obvious bias of using credit cards. For example "Christco Hampers" that are once a year Christmas mail-orders hampers come up as the #1 grocery supplier because just about all customers would use a credit card card. The two big supermarket chains that have about a 90% market share I believe come up as #2 and #3.

This wasn't about stopping taking pictures - the demand was to delete the pictures. Which he couldn't - it's a film camera.

Not that it's the point in the case, but with a film camera it is rather easy to delete your photos albeit at the expense of losing your other shots as well.

I suspect a few seconds of sun exposure is a whole lot harder to recover than deleted pictures on a DSLR, where you can just use a FAT undelete utility especially if no more pictures are taken afterwards.

I suspect many millions like myself have thousands of HD5970 cards busy mining bitcoins which probably accounts for some of it. Hell I had to install my own array of diesel generators after I realized that silicon solar cells can't be vertically stacked well.

Anyway I expect my cache of BTC will keep my family and myself financially secure for generations to come, even if air quality may be somewhat degraded.
