Zapcc high-speed C++ compiler now open source

Zapcc, a caching C++ compiler built for speed, has gone open source.

Ceemple Software, Zapcc’s builder, claims the compiler offers dramatic improvements in both incremental and full builds compared to building with Clang 4.0 and Clang 5.0. Based on heavily modified code from the Clang compiler project, Zapcc uses an in-memory compilation cache in a client-server architecture. All compilation information is remembered between runs.

Heterogeneous memory management meets EXPORT_SYMBOL_GPL()

One of the many longstanding — though unwritten — rules of kernel development is that infrastructure is not merged until at least one user for that infrastructure exists. That helps developers evaluate potential interfaces and be sure that the proposed addition is truly needed. A big exception to this rule was made when the heterogeneous memory management (HMM) code was merged, though. One of the reasons for the lack of users in this case turns out to be that many of the use cases are proprietary; that has led to some disagreements over the GPL-only status of an exported kernel symbol.

The HMM subsystem exists to support peripherals that have direct access to system memory through their own memory-management units. It allows the ownership of ranges of memory to be passed back and forth and notifies peripherals of changes in memory mappings to keep everything working well together. HMM is not a small or simple subsystem, and bringing it into the kernel has forced a number of low-level memory-management changes. After a multi-year development process, the core HMM code was merged for the 4.14 kernel, despite the lack of any users.

A broad overview of how modern Linux systems boot

 

For reasons beyond the scope of this entry, today I feel like writing down a broad and simplified overview of how modern Linux systems boot. Due to being a sysadmin who has stubbed his toe here repeatedly, I'm going to especially focus on points of failure.

Separation Architecture Supports Automotive Grade Linux

Green Hills Software now offers INTEGRITY Multivisor secure virtualization and advanced development tools for Automotive Grade Linux (AGL) on 64-bit automotive grade SoCs. For the first time, AGL applications can be added to automotive systems meeting the highest ISO 26262 safety levels through the INTEGRITY real-time operating system (RTOS). As a result, OEMs can confidently run AGL-based infotainment and connected car applications in secure partitions alongside safety-critical and security-critical functions including instrument clusters, rear-view camera, ADAS, OTA, gateway and V2X. The results are lower system costs, more scalable platforms, shorter development times and lower ASIL certification costs.

Second ONAP Open Source Network Automation Release Ships

The Linux Foundation announced the second software release from the Open Network Automation Platform (ONAP) project, a unified platform for end-to-end, closed-loop network automation

Announced last week, ONAP Beijing stems from the melding of two different open source networking automation projects under the direction of The Linux Foundation in March 2017. ONAP focuses on automating virtual network functions in software-defined networking (SDN) and network functions virtualization (NFV) implementations.

Getting started with Open edX to host your course

Now in its seventh major release, the Open edX platform is a free and open source course management system that is used all over the world to host Massive Open Online Courses (MOOCs) as well as smaller classes and training modules. To date, Open edX software has powered more than 8,000 original courses and 50 million course enrollments. You can install the platform yourself with on-premise equipment or by leveraging any of the industry-leading cloud infrastructure services providers, but it is also increasingly being made available in a Software-as-a-Service (SaaS) model from several of the project’s growing list of service providers.

The Open edX platform is used by many of the world’s premier educational institutions as well as private sector companies, public sector institutions, NGOs, non-profits, and educational technology startups, and the project’s global community of service providers continues to make the platform accessible to ever-smaller organizations. If you plan to create and offer educational content to a broad audience, you should consider using the Open edX platform.

Xapian Joins Conservancy as a Member Project

Software Freedom Conservancy proudly welcomes Xapian as Conservancy's newest member project. Xapian is a probabilistic information retrieval library that allows developers to add advanced indexing and search facilities to their own applications.

Conservancy, a public charity focused on ethical technology, is the home of over forty member projects dedicated to developing free and open source software. Conservancy acts as a corporate umbrella, allowing member projects to operate as charitable initiatives without having to independently manage their own corporate structure and administrative services.

"We've spent the past 18 years at Xapian developing a technologically mature software package," said Olly Betts, Xapian's Project Lead. "We're excited about how Conservancy can help us extend that maturity to our project governance."
