I never got the pleasure to have met him in person, but virtually any desktop computer owes a debt to him. Not only the computers using the the 6502 microprocessor he designed, but because the 6502 was so inexpensive (especially compared against the Intel and Motorola chips it competed with) that it made the possibility of a computer in everybody's home actually feasible. Here just in the very room I'm typing this, there is a Commodore 128D, several Commodore SX-64s (with the 8502 and 6510 respectively, variants of the 6502 with on-chip I/O ports), a Commodore KIM-1, a blue-label PET 2001, an Apple IIgs (technically with a 65816, the later WDC 16-bit variant), an Atari 2600 (6507, with a reduced address bus), an Atari Lynx (with the CMOS WDC WD65SC02), and an NEC TurboExpress (Hudson HuC6280, another modified WDC 65C02, with a primitive MMU). The 6502 appeared in fact in the Nintendo Famicom/NES (Ricoh 2A03 variant) and Super Nintendo (65816) and the vast majority of Commodore home computers before the Amiga, plus the Atari 8-bit and Apple II lines. For that matter, the Commodore 1541s and 1571s separate and built-into the 128D and SX-64s have 6502 CPUs too. Most impactful was probably its appearance in the BBC Micro series which was one of the influences on the now-ubiquitous ARM architecture.

Cloud Foundry sees top leadership change

For over a decade, Abby Kearns has been the face of the popular open-source, Platform-as-a-Service (PaaS) cloud, Cloud Foundry. First as the project manager for Pivotal Cloud Foundry and then as the Cloud Foundry Foundation's executive director. Now, Kearns' moving on to another executive position, and CTO Chip Childers has assumed her role as executive director. Childers brings vast experience with Cloud Foundry to the head chair. With five-years under his belt at Cloud Foundry as CTO, he and Kearns have both been Cloud Foundry's public faces. Before he came to Cloud Foundry, he had served as vice-president of Apache Cloudstack Infrastructure-as-a-Service (IaaS). In short, Childers knows cloud technology like the back of his hand.

The Strangest Operating Systems Ever Released

Ninety-nine percent of computer users don’t give a single thought to their operating system. It comes with the machine, it gets updated automatically, and that’s all there is to it. But here at PCMag, we like to talk about that other 1 percent. If you’re really interested in getting into the guts of how your home PC works, installing a new operating system is a fascinating way to do it. While there are many alternative OS choices with dedicated user bases, there are also some weird beasts out there, made for niche interests and unique hardware. Here’s a tour through some of the strangest operating systems ever released. Read more
