Het heeft gezorgd voor een andere manier van leven, voor kansen en problemen, grote technische uitdagingen en mogelijkheden. Met het krachtiger en goedkoper worden van apparatuur schuiven mobiele apparaten steeds meer op in de richting waar nu vaak nog 'normale' computers gebruikt worden. Het is de verwachting dat over niet zo heel veel tijd er geen onderscheid meer is. Hierdoor ontstaat de noodzaak voor nieuwe vormen van beheer en beveiliging van infrastructuur met mobiele apparaten, maar ook voor een andere manier van applicatieontwikkeling om te zorgen dat een apparaat zo lang mogelijk en zo fijn mogelijk gebruikt kan worden. Toevallig (of juist niet) zijn deze apparaten ook één van de grootste toepassingsgebieden voor Linux. Naast mobility gerelateerde onderwerpen komen dus ook de laatste technologie trends en ontwikkelingen van embedded Linux aan bod. Op deze conferentie hopen NLUUG en CELF u een goed beeld te geven van wat er nu al kan, waar de valkuilen zitten en vooral ook wat we op korte termijn kunnen gaan verwachten. We wensen u een plezierige en vooral ook een leerzame conferentie toe. Armijn Hemel, programmacommissie NLUUG & ELC Europe. 8 November 6 and 7 Introduction Introduction In the last 15 years mobile devices have radically altered the way companies and people live and work. This has led to a different way of life, brought chances and new possibilities as well as humongous technological challenges. In daily life mobile devices have become more powerful and cheaper, and they are moving into areas where until recently a 'normal' computer would be used. It is expected that in due time there will very little difference between the two. Mobile devices demand new ways of administration and securing infrastructure, but also ask for new techniques in writing applications, to make sure that they can be used for a long time in a productive way. Coincidentally (or maybe not) these devices are also one of the biggest emerging markets for the Linux operating system. This conference is not just talk about mobility, but also a look at the latest technology trends and developments of embedded Linux. At this conference NLUUG and CELF hope to give you a good view of what is possible right now, where the pitfalls are and especially what we can expect in the near future. We wish you a pleasant and useful conference. Armijn Hemel, programme committee NLUUG & ELC Europe. 9 Joint Keynote November 6 2008 Joint Keynote NLUUG & ELC Europe November 6 2008 10 November 6 2008 K1 How chip makers should (not) support free software Harald Welte HMW-consulting Silicon manufacturers, or rather design houses play a key aspect in how well their products are supported in Free Software oparating systems such as Linux. In the early Linux days - more than a decade ago - it was normal to have completely public technical reference manuals for the silicon, enabling Linux community developers to write drivers for the chips. After chip design houses start to realize there is an economically significant Linux market, they try to use their existing workflow, processes and development model for proprietary operating systems and try to apply this to Linux. The result are in many cases binary-only drivers for certain kernel versions and/or distributions or unmaintained, non-portable, coding style incompliant open source drivers for outdated kernel versions. Those kind of drivers are bound to create dissatisfaction within the Free Software developer community, among the Free Software users. Furthermore, they also result in inefficient use of R&D resources both inside and outside the chip vendor. Many silicon design houses still don't understand the Free Software and particularly Linux development model at all. This results in suboptimal support of their hardware products. In the end, customers are likely to buy from a different vendor. So what can chip design houses do to ensure excellent support of their products in the Free Software world? 11 K1 November 6 2008 Biography Harald Welte is a freelancer, consultant, enthusiast, freedom fighter and hacker who is working with Free Software (and particularly the Linux kernel) since 1995. His first major code contribution to the kernel was within the netfilter/iptables packet filter. He has started a number of other Free Software and Free Hardware projects, mainly related to RFID such as librfid, OpenMRTD, OpenBeacon, OpenPCD, OpenPICC. During 2006 and 2007 Harald became the co-founder of OpenMoko, where he served as Lead System Architect for the worlds first 100% Open Free Software based mobile phone. Aside from his technical contributions, Harald has been pioneering the legal enforcement of the GNU GPL license as part of his gpl-violations.org project. More than 150 inappropriate use of GPL licensed code by commercial companies have been resolved as part of this effort, both in court and out of court. He has received the 2007 "FSF Award for the Advancement of Free Software" and the "2008 Google/O'Reilly Open Source award: Defender of Rights". Harald is currently working as "Open Source Liaison" for the Taiwanese CPU, chipset and peripheral design house VIA, helping them to understand how to attain the best possible Free Software support for their components. He continues to operate his consulting business hmw-consulting. 12 November 6 2008 Talks NLUUG Talks NLUUG November 6 2008 13 N1 November 6 2008 WAN optimization: Pain XOR gain Ralf van Dooren Snow BV High latency, low bandwidth, slecht ontworpen protocollen (bv CIFS); allemaal factoren die werken op afstand er niet eenvoudiger op maken.

  • Montavista Linux Carrier Grade Edition
    MontaVista Linux Carrier Grade Edition WHITE PAPER ABSTRACT: Communications networks are very different from other kinds of computing applications. Networks require both very high reliability and very high performance. Not only must they process large volumes of data at high speed, but they must do so while limiting their downtime to minutes per year. Network failures can have huge economic consequences and can even result in the loss of life. Additionally, in this post-9/11 world, failure also has a national security dimension. This technical whitepaper introduces MontaVista Linux Carrier Grade Edition— what it is, how it evolved, and how it provides a foundation for developing and deploying carrier-grade applications like those described above.

  • The Growth of Android in Embedded Systems
    THE GROWTH OF ANDROID IN EMBEDDED SYstEMS THE LINUX FOUNDATION TRAINING PUBLICATION Written by Benjamin Zores OVERVIEW Linux has continuously grown in the embedded systems market for over a decade, gaining market share from proprietary operating systems. The proliferation of embedded devices, the explosion of open source development, the inherent hardware support, the incredible networking capabilities and the royalty-free economic model have all helped propel use of the Linux kernel into one of the best choices for the design of new embedded systems. While the success of Linux in the embedded market can not be denied, its notoriety was once confined to mostly technical professionals. That changed in 2008 with Google’s release of the Android mobile phone operating system, based on the Linux kernel. Thus began the tremendous growth of Linux in the consumer world, with over one million Android devices being activated every day in 2012 and predictions of total Android devices shipped reaching one billion in 2013. THE GROWTH OF ANDROID 1 IN EMBEDDED SYstEMS of Android in THE GROWTH Embedded Systems In a recent The Android Operating System survey, 34% Android’s success was no accident and was the result of a long-term strategy and loads of investment from Google. The early development of the OS came from within Android Inc. of embedded in the early 2000’s; it was purchased by Google in 2005. The original system relied on a Java framework for its application layer and was not based on the Linux kernel. Only after engineers are several years of development at Google labs, and after an architecture revamping, the first Android-based smart-phone (the HTC G1) was released and based on the very first version considering of the Android software development kit (SDK).

  • The History of Embedded Linux & Best Practices for Getting Started
    The History of Embedded Linux & Best Practices for Getting Started Henry Kingman July 2013 A Linux Foundation Training Publication www.training.linuxfoundation.org DISCLAIMER The Linux Foundation frequently works with subject matter experts on Linux educational pieces. In this publication, famed Linux Devices’ editor Henry Kingman has created a fun history and background on embedded Linux; we hope you enjoy Henry’s unique perspective on this fast-moving industry. The opinions found in this publication are Henry Kingman’s alone and don’t necessarily reflect those at the Linux Foundation. Overview This paper offers historical perspective and advice for those considering or planning to embed Linux. Before we plunge in, let’s define some terms: • By “Linux,” we mean any stack that includes a Linux kernel. Besides the kernel itself, stacks typically include a great deal of other software – typically the GNU C libraries, some graphics stack (like xorg), and the vendor’s particular software “value add.” However, a Linux device may include little more than a bootloader, bootstrap loader, and initramfs (i.e., a Linux kernel and a module or two running on a ramdisk). • By “embedded device,” we mean any device with a microprocessor, exclusive of PCs and servers. This describes the vast majority of computerized systems, since by most analyst estimates, PCs and servers consume only 1-5 percent of all microprocessor chips. The rest go into that vast, diverse, hard-to-generalize-about category known broadly as the “embedded” or “device” market. Many such systems, perhaps two thirds, have 8- and 16-bit “microcontrollers” that do not support “rich” 32-bit OSes like Linux.
