Where The Work Is Really Done – Casual Profiling

Once a program has been debugged and works properly, it might be time to start optimizing it. A common way of doing this is a method called profiling – watching a program execute and counting the amount of computing time each step in the program takes. This is all well …read more

Brain-mimicking chip uses different-colored light to learn and forget

The human brain is still a far more powerful computer than anything it itself has created so far. It’s no wonder then that engineers have recently focused on trying to emulate the structure of the brain with artificial synapses. Now, a team o… Continue reading Brain-mimicking chip uses different-colored light to learn and forget

A Nurse Call System Becomes Turing Complete

George Mallory, a famous English mountaineer, once suggested that it was of no use to climb mountains. Instead, he posited, the only reason to climb a mountain is because it is there. Likewise, when you become an expert in nurse call systems like those found in hospitals, you may find …read more

A Compiler in Plain Text Also Plays Music

As a layperson reading about some branches of mathematics, it often seems like mathematicians are just people who really like to create and solve puzzles. And, knowing that computer science shares a lot of its fundamentals with mathematics, we can assume that most computer scientists are also puzzle-solvers as well. This latest project from [tom7] shows off his puzzle creating and solving skills with a readable file which is also a paper, which is also a compiler for C programs, which can also play music.

[tom7] started off with the instruction set for the Intel 8086 processor. Of the instructions …read more
