Building Meego with OBS an Introduction to the Meego Build Infrastructure
» The Linux Foundation Building MeeGo with OBS An Introduction to the MeeGo Build Infrastructure .................. By Rudolf Streif, The Linux Foundation June 2011 A Publication By The Linux Foundation Characters from the MeeGo Project (http://www.meego.com) http://www.linuxfoundation.org Background Building a Linux distribution from scratch can be a daunting task. Besides the obligatory Linux kernel itself with its myriad of configuration options, a working Linux distribution requires hundreds if not thousands of additional packages to form a viable platform for desktop, server, mobile or any other type of specialized applications. For embedded Linux solutions, the complexity scales with the need to support multiple and different processor architectures, hardware platforms with limited resources, requirements for cross toolchains, and more. The MeeGo project leverages the strengths of the Open Build Service (OBS) for distribution and application development. MeeGo has established a 6-months release cadence mounting two releases per year in April and October in addition to maintenance releases in-between. To support this, the MeeGo OBS environment builds bootable MeeGo images for the various MeeGo device categories and user experiences (Handset, Netbook, Tablet PC, In-vehicle Infotainment, and Smart TV) targeting multiple different hardware platforms for IA, ARM, etc. For application development, the MeeGo OBS allows developers to easily build their software packages utilizing the same infrastructure the MeeGo distributions were built with, validating dependencies and providing binary compliance. In this whitepaper, we will provide a brief introduction to the MeeGo build infrastructure and how it is utilized to support the MeeGo development process. Then we demonstrate the use of the OBS WebUI and the command-line client osc with step-by-step instructions. -

Concurrent Programming Made Simple: the (R)Evolution of Transactional Memory
Concurrent Programming Made Simple: The (r)evolution of Transactional Memory Nuno Diegues∗1 and Torvald Riegely2 1INESC-ID, Lisbon, Portugal 2Red Hat October 1, 2013 ∗[email protected] [email protected] 1 1 Harnessing Concurrency Today, it is commonplace for developers to deal with concurrency in their applications. This reality has been driven by two ongoing revolutions in terms of hardware deployments. On one hand, processors have evolved to a multi- core paradigm in which computational power increases by increasing number of cores rather than by enhancing single thread performance. On the other hand, cloud computing has democratized the access to affordable large- scale distributed platforms. In both cases programmers are faced with a similar problem: if they want to scale out their applications, then they need to tackle the issue of how to synchronize access to data in face of ever growing concurrency levels. For many decades, programmers have been taught to rely on locking mechanisms or centralized components to manage concurrent accesses to data. However, the ongoing architectural trends towards massively parallel/large- scale systems have unveiled the limitations of traditional synchronization schemes — not only can they significantly limit the feasible parallelism, when there may exist tremendous untapped parallel potential; they also force to use intricate programming models that are prone to tricky concurrency bugs, which can be a conundrum to detect and fix. In fact, popular knowledge considers locking approaches simple to understand, but difficult to master. 2 Programming with Transactions To tackle this fundamental problem in modern software development, during recent years both industry and academia have started to adopt Transactional Memory (TM). -
