Sebastian Anthony, writing for ExtremeTech:
There are two key breakthroughs here. First, IBM has managed to build a monolithic silicon chip that integrates both electrical (transistors, capacitors, resistors) and optical (modulators, photodetectors, waveguides) components. Monolithic means that the entire chip is fabricated from a single crystal of silicon, on a single production line; i.e. the optical components are produced at the same time as the electrical components, using the same process. There aren’t two separate regions on the chip that each deal with different signals; the optical and electrical components are all mixed up together to form an integrated nanophotonic circuit.
Second, and perhaps more importantly, IBM has manufactured these chips on its 90nm SOI process — the same process that was used to produce the original Xbox 360, PS3, and Wii CPUs. According to Solomon Assefa, a nanophotonics scientist at IBM Research who worked on this breakthrough, this was a very difficult step. It’s one thing to produce a nanophotonic device in a standalone laboratory environment — but another thing entirely to finagle an existing, commercial 90nm process into creating something it was never designed to do. It sounds like IBM spent most of the last two years trying to get it to work.
This could potentially be a really big deal. The power and heat profiles of optical systems are different from those of electrical systems.

Jack Tramiel, founder of Commodore International and former CEO of Atari International, died on Sunday at the age of 83. He was surrounded by family at the time of his passing, according to Forbes.
Famous for saying that computers should be built “for masses, not the classes,” Tramiel played an important role in the early days of personal computing and video gaming, as his company introduced a line of powerful but affordable home computers, including the popular Commodore 64.
I was honestly not familiar with Tramiel by name at all until reading this, but the Commodore 64 was a legendary computer. My older brother even had one, although I was only a few years old at the time so I sadly don’t remember a thing about it.
Here’s some music generated from one line C programs. Neat.
Viznut wrote a lot on the origin and theory behind this stuff on his blog, and there are a couple more videos there too. There’s also a mathematical analysis for the numbers nerds.
Here’s Andrew Salamone showing off some garments he’s made with a hacked knitting machine that can “print” monochrome bitmap images. Included is a sweater of Bill Cosby wearing a sweater of Bill Cosby wearing a sweater of Bill Cosby wearing a sweater of…
I’m pretty sure this is part of a creation myth somewhere.
Andy Rooney will announce on this Sunday’s “60 Minutes” that it will be his last regular appearance on the broadcast. Rooney, 92, has been featured on “60 Minutes” since 1978.
He will make the announcement in his regular essay at the end of the program, his 1097th original essay for “60 Minutes”. It will be preceded by a segment in which Rooney looks back on his career in an interview with Morley Safer.
Rooney began his run on “60 Minutes” in July 1978 with an essay about the reporting of automobile fatalities on the Independence Day weekend. He became a regular feature that fall, alternating weeks with the dueling James J. Kilpatrick and Shana Alexander before getting the end slot all to himself in the fall of 1979. In Rooney’s first full season as the “60 Minutes” commentator, the broadcast was the number one program for the first time.
As a tribute to the world’s greatest living commentator, we here at Nullary Sources would like to share with you some of our favorite Andy Rooney moments. Here he is rambling in his inimitable style about typewriters and computer usability.
