Displays Of A Different Stripe

New image-management techniques provide brightness for half the power, easing the brutal tradeoff in video-rich gadgets

Best By Test: In a comparison of images, at a particular power level, a PenTile red-green-blue-white display (right) will outshine a conventional red-green-blue stripe display (left) hands down, yielding colors that are more vivid and distinct.

Today’s flat-panel displays provide bright, crisp, and vivid images--and they use plenty of power while doing it. It’s a tradeoff that hardly mattered when we rarely watched movies, played games, or surfed the Web on anything other than furniture-size monitors. But that power consumption is a serious engineering constraint today, when more and more of us are getting our visual data on the go, from cellphones, video iPods, and game players like Sony’s PSP. And as serious as the constraint is now, it will soon become downright intolerable as engineers strive to wring far more vivid visual information out of the next generation of portables than can be displayed by anything now on the market.

Fortunately, remarkable power savings--as much as 50 percent--can be achieved by simply redesigning the display to provide no more information than the eye can absorb and the brain can digest. This strategy is called biomimetic, because it deliberately mimics a living system.

The EV Transition Explained: Battery Challenges

Batteries expose supply chain and skills gaps

“Energy and information are two basic currencies of organic and social systems," the economics Nobelist Herb Simon once observed. "A new technology that alters the terms on which one or the other of these is available to a system can work on it the most profound changes.”

Electric vehicles at scale alter the terms of both basic currencies concurrently. Reliable, secure supplies of minerals and software are core elements for EVs, which represent a “shift from a fuel-intensive to a material-intensive energy system,” according to a report by the International Energy Agency (IEA). For example, the mineral requirements for an EV’s batteries and electric motors are six times that of an ICE vehicle, which can increase the average weight of an EV by 340 kgs (750 pounds). For something like the Ford Lightning, the weight can be more than twice that amount.

Ownership of AI-Generated Code Hotly Disputed

A copyright storm may be brewing for GitHub Copilot

GitHub Copilot dubs itself as an “AI pair programmer” for software developers, automatically suggesting code in real time. According to GitHub, Copilot is “powered by Codex, a generative pretrained AI model created by OpenAI” and has been trained on “natural language text and source code from publicly available sources, including code in public repositories on GitHub.”

However, a class-action lawsuit filed against GitHub Copilot, its parent company Microsoft, and OpenAI claims open-source software piracy and violations of open-source licenses. Specifically, the lawsuit states that code generated by Copilot does not include any attribution of the original author of the code, copyright notices, and a copy of the license, which most open-source licenses require.

Learn How Global Configuration Management and IBM CLM Work Together

In this presentation we will build the case for component-based requirements management

2 min read

This is a sponsored article brought to you by 321 Gang.

To fully support Requirements Management (RM) best practices, a tool needs to support traceability, versioning, reuse, and Product Line Engineering (PLE). This is especially true when designing large complex systems or systems that follow standards and regulations. Most modern requirement tools do a decent job of capturing requirements and related metadata. Some tools also support rudimentary mechanisms for baselining and traceability capabilities (“linking” requirements). The earlier versions of IBM DOORS Next supported a rich configurable traceability and even a rudimentary form of reuse. DOORS Next became a complete solution for managing requirements a few years ago when IBM invented and implemented Global Configuration Management (GCM) as part of its Engineering Lifecycle Management (ELM, formerly known as Collaborative Lifecycle Management or simply CLM) suite of integrated tools. On the surface, it seems that GCM just provides versioning capability, but it is so much more than that. GCM arms product/system development organizations with support for advanced requirement reuse, traceability that supports versioning, release management and variant management. It is also possible to manage collections of related Application Lifecycle Management (ALM) and Systems Engineering artifacts in a single configuration.
