    use of an upgradeable read only code frame clearly mimicking set top boxes that can upgrade themselves OTA over the air for example from a satellite channel ChromiumOS is capable of managing in a transparent and secure way this upgrade handling securely interruptions and attacks This coupled with a totally encrypted local store means that the hardware can be effectively thought as a purely ephemeral device that can substituted with limited configuration needs and that large numbers of devices can be upgraded and managed without human intervention and in total security Applications are embedded in web pages and managed as web pages so the maintenance and training requirements are limited It is not really tied into Google Of course in this first release it heavily uses Google services for everything but changing that is trivial The authentication part is managed by a PAM module that can be easily swapped and login completion that actually turns your login name in a gmail account is just a small modification of the SLiM login manager used by the OS to perform the initial login and can be changed with a few lines of code The same for the application list the first icon on the top left of the screen that is merely a hardwired URL change it with your own portal address and you get the same result without using Google The only part that requires some work is the integration of Google SSO through a complex cookie exchange mechanism augmenting that with something like OpenSSO from Sun would not require more than a few days of work anyway It is not a SplashTop clone There are several Linux based instant on environments designed to be integrated inside of a flash BIOS the most famous one is SplashTop used in many motherboards and notebooks from Asus Acer HP Sony and many others The problem of this approach is that it is fixed the image is difficult to update and upgrade and this means that it rapidly loses appeal ChromiumOS uses a trusted boot mechanism to ensure that upgrades are legitimate but integrates it in a clean and smart way making sure that the users will continuously be up to date It does require the net most of the time but not always The first login requires a working connection but then the credentials are hashed and stored in a cache wallet that allows to enter even in absence of a connection If the pages allow for detached operation using Gears HTML5 persistent storage or similar mechanisms the system will work even without a connection It is a stopgag solution but is sensible most of the time spent in desktop applications is centered on online services that are unusable without a connection so it makes sense when considering the OS as something that is not competing in the same market as a traditional PC Local cached web applications may provide in the future more flexibility in this sense but moch effort needs to

    attribute of open source software At the same time saying that proprietary software has lower ongoing cost is not overall true and I have tons of independent confirmation of that claiming that proprietary has more features is as before not universally true saying that proprietary software maintains backward compatibility generated substantial laughter across the poor people here in the office that has to provide support to our commercial customers claiming that proprietary is more secure recalled the recent attack against DNS claiming that it was poorly protected freeware Should I continue Open standards anyone And the last one implying that only proprietary software is based on managed development Any commercial OSS vendor would happily dismiss this claim as untrue Commitment on support I believe that my fellow three readers would not encountering any difficulties in thinking about proprietary products that got bought and buried underground or that simply got scrapped altogether Ah I would happily send my guide to this fellow slide author but I believe that probably this would not change this company views a single bit FLOSS open source 1 Comment You are currently browsing the archives for Monday October 5th 2009 blog divertissements EveryDesk OSS adoption OSS

    and open services Open Cloud Tribune Following the various discussions and controversies around the topic FLOSS and Cloud Computing this opinion column aims to nourish the debates on this issue by freely publishing the various opinions and points of view 2009 s article questions about the impact of Cloud Computing on employment in IT Contradictory evolutions While significant progress was observed in line with 2020 FLOSS Roadmap the 2009 Synthesis highlights contradictory evolutions the penetration of FLOSS continues but at political level there is still some blocking In spite of recognition from intellectuals the alliance between security and proprietary has been reinforced and has delayed the evolution of lawful environments In terms of public policies progress is variable Except in Brazil United Kingdom and the Netherlands who have made notable moves no other major stimulus for FLOSS has appeared on the radar The 2009 Synthesis is questioning why governments are still reluctant to adopt a more voluntary FLOSS attitude Because FLOSS supports new concepts of society and supports the links between technology and solidarity it should be taken into account in public policies Two new issues Considering what has been published in 2008 two new issues have emerged which will need to be explored in the coming months proprietary hardware platforms which may slow the development of FLOSS and proprietary data which may create critical lock ins even when software is free The global economic crisis While the global crisis may have had a negative impact on services based businesses and services vendors specializing in FLOSS it has proved to be an opportunity for most FLOSS vendors who have seen their business grow significantly in 2009 When it comes to Cloud based businesses the facts tend to show a massive migration of applications in the coming months Impressive growth in terms of hosting is paving the way for these migrations Free software and financial system this new theme of the 2020 FLOSS Roadmap makes its appearance in the version 2009 in order to take into account the role which FLOSS can hold in a system which currently is the target of many reflexions Sun Oracle The acquisition of Sun by Oracle is seen by contributors to the 2009 Synthesis as a major event with the potential risk that it will significantly redefine the FLOSS landscape But while the number of major IT players is decreasing the number of small and medium size companies focused around FLOSS is growing rapidly This movement is structured around technology communities and business activities with some of the business models involved being hybrid ones FLOSS is like forests The 2009 Synthesis puts forward this analogy to make it easier to understand the complexity of FLOSS through the use of a simple and rich image Like forests and their canopies which play host to a rich bio diversity and diverse ecosystems FLOSS is diverse with multiple layers and branches both in term of technology and creation of wealth Like a forest FLOSS provides vital oxygen to

    step in a more appropriate commercialization structure that for efficiency reason should be composed of a commuity managed or at least transparently managed consortia that manages the core of what now is the open source part of open core offerings and a purely proprietary company that provides the monetization services may those be proprietary add ons paid services and so on Why Because the current structure is not the most efficient to enable participation from outside groups if you look at the various open core offerings the majority of the code is developed from in house developers while on community managed consortia the code may be originated by a single company but is taken up by more entities The best example is Eclipse as recently measured 25 of the committers work for IBM with individuals accounting for 22 and a large number of companies like Oracle Borland Actuate and many others with percentages that go from 1 to 7 in a collective non IBM collaboration Having then a pure proprietary company that sells services or add ons also removes any possibility of misunderstanding about what is offered to the customer and thus will make the need of a OSS checklist unnecessary Of course this means that the direction of the project is no longer in the hand of a single company and this may be a problem for investors that may want to have some form of exclusivity or guarantee of maintaining the control But my impression is that there is only the illusion of control because if there is a large enough payoff forks will make the point moot exactly like it happened with MySQL and by relieving control the company gets back a much enlarged community of developers and potential adopters FLOSS open source 3 Comments You are

    can happen It is not just a question of religious beliefs but practical thinking is the software yours Does the service you are using gives you the opportunity of moving somewhere else What happens if the developers are not going in the direction you need If we consider this as the basis for discussion lots of arguments in the OSS FS camp become much simpler The crusade against software patents is a way of defending the rights of use of the end user against arbitrary legal attacks in this sense the only real reason for being not happy of having something like Mono is not the fact that it is a Microsoft standard but the fact that it is probably covered by unknown patents The same thing applies for Flash most people is dependent from a single company for what amounts as a platform still not replicated by OSS alternatives like Gnash and in any case potentially covered by patents not only by Adobe but by many other companies as well The victory of pragmatism that Matt proclaims is not actually related to FS and OSS that are the same exact thing but the general overcoming of emotional based arguments that is absolutely a positive thing But the new pragmatism should also be viewed with suspicion exactly as the claims that free software is better without reason I will make the example of Mono now it is pushed as a way to overcome what is equally proprietary that is Flash What happens when Microsoft stops promoting it It is OSS s0 it can theoretically go on forever but very few will risk infringing patents with it and so it will remain more or less limited to those shops already using NET elsewhere thus having paid for the right of use limiting its growth potential The scenario is not so unbelievable after the unveiling of a real Silverlight port to Moblin that makes Mono more or less redundant Some open core systems suffer of the same problem the user is forced by the proprietary part to abide to whatever decision is made by the vendor independently of what OSS license the open part is licensed with The uncritical embracing of online services is similarly flawed what happens if the company goes bankrupt or discontinue the service If you use EC2 you can always create your own infrastructure using Eucalyptus and continue your work Can you say the same of all the services that are being promoted right now Can you get a complete copy of your data move it somewhere else Control is what really matters on premise and online Who how such control is performed what it may affects You may prefer the ethical angle like Stallman did or the economic angle like I do but the end result is the same exactly like free software and open source are the same The critical aspect is being able to assess this control and weight if the lack of control is
