I assume this is something internal to Flickr and am mildly concerned about their deployment of some system that would wantonly blast tuna from the waters.
I like tuna. They're high on the food chain, and convert small fish into one large fish so they can be easily fished, and canned. Canned tuna is great for pasta. Wikipedia also tells us:
Many tuna species associate with dolphins, swimming alongside them. These include yellowfin tuna in the eastern Pacific Ocean, but not albacore or skipjack. The reason for the association is believed to be the avoidance of dolphins by sharks, which are predators of tuna. Swimming near dolphins reduces the likelihood of the tuna being attacked by a shark.They're smart enough to avoid sharks, just so they can end up in cans. For us.
Conclusion: tuna is awesome.
So why is Flickr blasting tuna?!
I searched on Google, and found this photo of John deploying the tuna blaster.
Further digging via the tunablaster tag, revealed another mysterious clue:
And finally, I landed on a Google Base entry for Tuna Blaster.
Thus far all I can establish is that John Allspaw has an insidious plan to blast tuna from our oceans. But for what purpose?
On a semi-related note, despite his tuna murdering tendencies, John does produce some useful stuff, including some neato system visualisations.
