A Canadian cottage-goer developed a deafness-inducing ear-wax-clot from excessive swimming; a doctor on the cottage-island decided to substitute a handy SuperSoaker water-gun for a syringe and got great results -- so great that he wrote them up for the Canadian Medical Association Journal.
D.K. (a family and emergency physician) assessed the utility of the Super Soaker Max-D 5000. He was surprised to note that it was able to deliver a superbly pressured narrow stream of water equivalent to, or perhaps exceeding, the quality of that achieved with standard ear-syringing instruments. The owner of the Super Soaker Max-D 5000 was sought out; after hearing an explanation of its intended application, he granted permission for its use.
Verbal consent (covering risks and benefits) was obtained from the patient. He then changed into swimming shorts, located himself on an ideal location on the deck and held a Tupperware container (product number 1611-16) to the side of his neck, in lieu of a kidney basin. The Super Soaker Max-D 5000 was filled with body-temperature water and then mildly pressurized using the blue hand-pump. The trigger was depressed, releasing a gentle, narrow jet of water, which was then aimed along the posterior wall of the ear canal (Fig. 1). After approximately 15 seconds, the jet was aimed along the anterior wall. This cycle was repeated (with occasional repressurizing) until the Super Soaker was empty.
Midway through the second load's stream, wax particles began to run out of the ear. Just after starting the third load, a large plug of wax burst forth from the patient's ear. The 3 generations of family members present took turns admiring (or recoiling from) the specimen. The patient exclaimed in joy, "I can hear again!"

David Robinson used the data from the 28,657 people who self-selected to take the Stack Overflow survey to investigate the relationship between programmer pay and the conventions of using either tabs or spaces to mark indents, and found a persistent, significant correlation between using spaces and bringing home higher pay.
It’s the end of an era, sort of: Fraunhofer IIS, the developers of the MP3 audio compression format, announced that they are ceasing their licensing program.

As the old saying goes, “You should sit in meditation for 30 minutes every day. Unless you are too busy, in which case you should meditate for an hour.” Since most of us have an endless list of things to do and people to see, carving out quiet time can feel impossible, especially when most […]
