on 9 September 1947,

US Navy technician fixed a fault in a Harvard Mark II computer by removing a moth that was caught between the contacts of a relay in the system.

This event is often thought to be the origin of the terms, “bug” and “debug“, in reference to computer problems.

Even though use of word “bug” in other device is actually in Pall Mall Gazette from 1889

The mobile unit comes with one solar panel as standard and the heating component is an extra USD$400. The design also provides the flexibility to incorporate other alternative forms of power generation such as wind power.

The product is now available, but the company says that due to high-demand it is currently only selling the systems for commercial applications. Both McDonald’s and the US Navy are testing Greencore’s solar cooling systems.

Mosquito Wisdom

In a way to office, that thought just eventually exist in my mind. Mosquito is a very unique bug because it cannot have AIDS even tough it’s suck human blood from AIDS person. So maybe vaccine from AIDS can be come from this animal. But that not thought came in my mind, thought that came my mind is :

if mosquito suck blood it will suck until the mosquito is full, and that will affect the flying maneuver. if mosquito full it will hard to maneuver in flying, and then it will become death, because person which is bite by them will kill them.

So the mosquito wisdom is “don’t be a greedy person because it will kill you”.
