Fixer works without assistance from humans and without access to a program’s underlying source code. Instead, the system monitors the behavior of a binary. By observing a program’s normal behavior and assigning a set of rules, Fixer detects certain types of errors, particularly those caused when an attacker injects malicious input into a program. When something goes wrong, Fixer throws up the anomaly and identifies the rules that have been violated. It then comes up with several potential patches designed to push the software into following the violated rules. (The patches are applied directly to the binary, bypassing the source code.) Fixer analyzes these possibilities to decide which are most likely to work, then installs the top candidates and tests their effectiveness. If additional rules are violated, or if a patch causes the system to crash, Fixer rejects it and tries another.
Fixer is particularly effective when installed on a group of machines running the same software. In that case, what Fixer learns from errors on one machine, is used to fix all the others. Because it doesn’t require access to source code, Fixer could be used to fix programs without requiring the cooperation of the company that made the software, or to repair programs that are no longer being maintained.
But Fixer’s approach could result in some hiccups for the user. For example, if a Web browser had a bug that made it unable to handle URLs past a certain length, Fixer’s patch might protect the system by clipping off the ends of URLs that were too long. By preventing the program from failing, it would also put a check on it working full throttle.

The x2 is an experimental helicopter being developed by Sikorsky, an American company, which hopes it will be zipping along at more than 460kph. The company, however, is interested in more than just breaking speed records. It plans to use the technology developed for the x2 in commercial helicopters.
Sikorsky reckons that future helicopters built using the x2 technology would be extremely versatile machines. They would dash to and from a medical emergency a lot faster. They would also be very agile in flight, which would increase their capabilities in combat.

It was once considered the ‘port of death’ in the 19th century. Ships tended to avoid docking at the wood plank port, fearing the yellow fever. The floods in the city’s area provoked illnesses and once the bubonic plague almost decimated the population.
In the early 20th century, major urbanization created the port’s modern structure seen today, eliminating the risk of diseases and providing the port with modern, industrial-age infrastructure.
The first railway link from the port to the state capital São Paulo City, 79 km away, and the state’s interior, was completed in 1864. This allowed for an easier transportation of the vast masses of migrant workers who headed to São Paulo and the state’s numerous coffee farms.
Millions of immigrants reached Brazil via the port of Santos in the late 19th and early 20th centuries, proceeding to the country’s interior by railway. Santos was for a few decades the true gateway to Brazil for millions of immigrants.
