Probably it will sound strange or slow to you but my ISP upgraded to optical fiber and now I got 50Mbps from 20Mbps that I had before. I downloaded 1GB file in 3min. I'm so fucking happy.

Here in Saint Petersburg, Russia, our local governmental utility company that is responsible for providing tap water for the entire city, uses crayfish to monitor the water composition.

There are some crayfishes living at the plant and there are some scientists that constantly monitor the crayfish via optical fiber to measure how they feel. If crayfish feels bad, the water is cut out and the inspection begins. There are operators that are paid to watch for crayfish mood throughout the day.

This system works flawlessly since 2005 and helped prevent several accidents when toxic stuff that can’t be monitored on a large scale ended up in our local river.

I mean coal miners was using canaries and rats for years to detect what detectors just can’t detect good enough.

Our entire tap water system depends on some crayfish and it’s amazing.

Coming back home to find out that my parents switched to optical fiber and can download with 50MB/s WiFi speeds makes me feel sad to go back to my 15MB/s campus speed. Even more when I go to Germany.

You have to work, but you notice a fiber in your web cam. Clean the lens, but its still there. Open the web cam to the last bit and clean the optical chip.. There you fixed the web cam, but what about the work..
