On Wednesday, acting FAA Administrator Chris Rocheleau told the House Appropriations Committee that the Federal Aviation Administration plans to replace its aging air traffic control systems, which still rely on floppy disks and Windows 95 computers, Tom's Hardware reports. The agency has issued a Request For Information to gather proposals from companies willing to tackle the massive infrastructure overhaul.

"The whole idea is to replace the system. No more floppy disks or paper strips," Rocheleau said during the committee hearing. Transportation Secretary Sean Duffy called the project "the most important infrastructure project that we've had in this country for decades," describing it as a bipartisan priority.

Most air traffic control towers and facilities across the US currently operate with technology that seems frozen in the 20th century, although that isn't necessarily a bad thing—when it works. Some controllers currently use paper strips to track aircraft movements and transfer data between systems using floppy disks, while their computers run Microsoft's Windows 95 operating system, which launched in 1995.

On Thursday, pioneering computer engineer and Apple veteran William "Bill" Atkinson died of pancreatic cancer at his home in Portola Valley, California, surrounded by family. He was 74. "We regret to write that our beloved husband, father, and stepfather Bill Atkinson passed away," his family wrote on Facebook. "He was a remarkable person, and the world will be forever different because he lived in it."

As Apple employee No. 51, Atkinson transformed abstract computer science into intuitive visual experiences that millions would use daily: His QuickDraw graphics engine made the Macintosh interface possible; he introduced the wider world to bitmap editing with MacPaint; and HyperCard presaged hyperlinked elements of the World Wide Web by years.

"I say this with no hyperbole: Bill Atkinson may well have been the best computer programmer who ever lived," wrote veteran Apple analyst John Gruber on Daring Fireball in a tribute. "Without question, he's on the short list. What a man, what a mind, what gifts to the world he left us."

On Tuesday, classic computer collector Joe Strosnider announced the availability of a new 3D-printer filament that replicates the iconic "Platinum" color scheme used in classic Macintosh computers from the late 1980s through the 1990s. The PLA filament (PLA is short for polylactic acid) allows hobbyists to 3D-print nostalgic novelties, replacement parts, and accessories that match the original color of vintage Apple computers.

Hobbyists commonly feed this type of filament into commercial desktop 3D printers, which heat the plastic and extrude it in a computer-controlled way to fabricate new plastic parts.

The Platinum color, which Apple used in its desktop and portable computer lines starting with the Apple IIgs in 1986, has become synonymous with a distinctive era of classic Macintosh aesthetic. Over time, original Macintosh plastics have become brittle and discolored with age, so matching the "original" color can be a somewhat challenging and subjective experience.
