Shotwell https://wiki.gnome.org/Apps/Sh... is very nice for browsing/tagging. I just wish it had a more advanced raw editing mode like RawTherapee or Darktable.
RawTherapee is great for editing the raw files, but I wish it had a better browser to photos. My perfect software would probably have shotwell as the browser/tagger and RawTherapee as the editor.
I was pleased to see that Matplotlib switch to Grace Hopper as their test image. http://matplotlib.org/examples...
Actually yes, assuming you have a phone (or similar) with GPS.
There are a couple of projects collecting locations of cell phone towers and wifi hotspots to allow geolocation to devices without GPS and faster geolocation for with GPS. Having opensource databases means you can do lookup without having to report your location to a google/apple/nokia and means you can do offline look ups. See https://location.services.mozi... or http://wiki.opencellid.org/wik... or http://openbmap.org/
If you are cycling on cycle paths, then you could record GPS traces and upload them to openstreet map. That will require a bit of time on the computer, but the valuable work is the actual recording.
e.g. Pluma which is a continuation of gedit 2.x maintained by the MATE project.
Eizo have been making lots of interesting monitors including 1x1 for a long time, eg

I live and work in a big city, so I cycle and use public transport for about 98% of my journeys. The remaining few percent I take a taxi, which is expensive but rare enough that its not an issue. If it were 5% journeys that I could not do by bike/bus/train then I would probably have to get a car, in which case probably 90% of my journeys would be by private car.
So if you make taxis cheaper, then maybe there are a lot of people who would no longer need a car for those occasional journeys where public transport or bike is not a good option. They can then use public transport most of the time, and taxis occasionally. In cities a bus is always going to be the cheapest (unless the price of fuel and labour drops to zero)
Because quantities do matter. 8 Bq/Tonne is tiny. If you drank this water for a year (3 litre per day), and your body somehow managed to store every Caesium atom, then that would be less radiation than 1 banana and less than 1% the radiation that is in your body naturally.
All this article shows is that radiation is easy to detect, even in tiny quantities, and gamma ray spectroscopy lets you identify the isotope, which in some cases means you can trace the origin.
The "no safe level" meme is mad. Its like saying that because if car hits you at 50 mhp you have a 50% chance of dying, so if it hits you at 1mph you have a 1% chance of dying (linear no threshold), even a 1 in a million chance of dying is dangerous, so even cars travelling at the speed of continental drift are dangerous.
There are more different units for distance. Actually its all the units for brightness that confuse me the most.
There are actually really only 2 physical units,
Activity, i.e. decays per second, Becquerel
Absorbed does, i.e. joule per kg, Greys
and a bonus biologically adjusted
Equivalent dose, like Greys adjusted by biological harm, Sievert
The others are obsolete (only used in USA).
So 2 tonnes of water has the same amount of radiation as 1 banana.
