Open-source microprocessor

Filed under
OSS

Software source codes and hardware designs tend to be closely guarded trade secrets. Not so with open-source products. For instance, the code of open-source software is freely available to all: the best known example is the Linux operating system. Not only are interested developers able to use the software, they can also further develop it and adapt it to their own needs.

Open-source products also exist on the hardware side. Examples are open micro-controller boards such as Arduino or Raspberry Pi, of which blueprints are publicly available. However, these boards are based on commercial chips, whose internal architecture is not open-source. A few days ago, scientists at ETH Zurich and the University of Bologna, led by ETH Professor Luca Benini, open sourced the full design of one of their microprocessor systems - in a way that maximises the freedom of other developers to use and change the system, says Benini. "It will now be possible to build open source hardware from the ground up."

Cloud convenience is killing the open source database

Open source has never been more important or, ironically, irrelevant. As developers increasingly embrace the cloud to shorten time to market, they're speeding past open source, making it even harder to build an open source business. After all, if open source were largely a way for developers to skirt legal and purchasing departments to get the software they needed when they needed it, the cloud ups that convenience to the nth degree. In Accel's annual business review, the vaunted venture capital firm writes: "'Product' is no longer just the bits of software, it's also how the software is sold, supported, and made successful." The cloud is changing the way all software is consumed, including open source. Read more

Why the operating system matters even more in 2017

Operating systems don't quite date back to the beginning of computing, but they go back far enough. Mainframe customers wrote the first ones in the late 1950s, with operating systems that we'd more clearly recognize as such today—including OS/360 from IBM and Unix from Bell Labs—following over the next couple of decades.

OpenGov Partnership members mull open source policy

The Open Government Partnership (OGP) will suggest to its member governments to create a policy on open source. This week, a draft proposal is to be finalised at the OGP Global Summit in Paris. Read more
