  • Some EveryDesk Use Cases « carlodaffara.conecta.itcarlodaffara.conecta.it
    To summarize desktop PC are flexible adaptable usable without connectivity complex fragile difficult to manage Thin bitmap based like RDP or ICA clients are slightly easier to manage require little support require substantial infrastructure investments cannot work detached have marginally lower management costs We try to strive with a middle ground solution EveryDesk is a locally executed OS that when configured provides the same remote management advantages of thin clients without the costly infrastructure the only thing needed is storage that is nowadays cheap and plentiful The system is a real install not a live CD so the user administrator can install applications or customize it in depth simply by using the image and then replicating it for all the people working in a company or administration Updating it is simple just execute the Update Manager While developing EveryDesk we identified a few potential use cases and I would like to explain what advantage our hybrid model can have Hospital worker our initial use case We designed the system so that national regulations in the handling of sensitive data could be complied to without any specific effort on the side of the user that is to make nearly impossible for the worker to lose or disseminate data without an explicit and voluntary breach of confidentiality and make it possible to identify such breach immediately By moving user data on a centrally managed server standard logging and identity management techniques can be applied easily to prevent data loss as no private data is on the key including passwords losing the key or having it stolen is not sufficient to breach the system privacy For our health care customization we added to the basic image an excellent radiology workstation system called O3 already in use in some Italian hospitals a medical dictionary and some ancillary tools like the ImageJ image processing system Another important use case is widely found in developing countries and is the Internet Café While it is true that mobile internet access is fast becoming a fundamental infrastructure cost and efficiency reasons still make it sensible to have a physical shared space with PCs EveryDesk makes it possible to provide low maintenance PCs with no hard disks a central low cost storage and simply give away the USB keys to the attendees If a key stops working it is simply a matter of re copying the image on top of a new one to restore everything Within companies and Public Administration providing a diskless PC with EveryDesk allows the efficient use of even old PCs EveryDesk takes 150MB of RAM with both Firefox and OpenOffice org open while providing thanks to VirtualBox the set of applications that are not available within Linux In dispersed companies where you have multiple sites you can use a replicating file system like the wonderful XtreemFS developed within another EU funded research project that provides in a totally open source solution with differential and efficient replicas across sites This way you can use your

    The Windows Phone 7 chassis strategy allows devices to be created faster saving significant engineering cost It s essentially plug and play with device drivers authored by Microsoft This apart from the use of the clearly pejorative mention of fragmented mess is naturally true It is also another surprise the reason of Windows success namely the external ecosystem of hardware devices mostly unpredictable that were basically developed and managed outside of Microsoft control After much bashing of Apple s walled garden now Microsoft seem to imply that the same model that brought them success is now useless and that to win in mobile you have to adopt Apple centrally managed hardware experience It may be true or not but I suspect that hardware manufacturers will be more happy to create many permutation and device models designed for different price points and different users in a way that would be incompatible with MS central control and central device driver development What happens if I need to push on the market a device that deviates from the MS chassis Will MS write the driver for me for free What if it doesn t want to write it The chassis model is nice if you are Apple and are selling basically a single or a few models if you are going to market with many hardware vendors you are forcing the same undifferentiated hardware on all OEM and this is a great no no How are you going to go against competitors that do employ exactly the same model bill of material same procurement channel Also this phrase is a clear indication that someone inside of MS still don t understand what real open source is about The amount of engineering necessary for creating a complex product out of OSS is substantially lower than proprietary alternatives as I demonstrated here and here the driver development effort can easily be shared among many different projects that use the same component lowering the development costs substantially Windows Phone 7 has a software update architecture designed to make it easy for OEMs to plug in their custom code independent of the OS code We ve seen the delays due to Android OEMs having to sink engineering resources into each and every Android update Some Android OEMs skip updates or stop updating their less popular devices Because of the unique update architecture Windows Phone 7 OEMs don t need to roll their own updates based on the stock build Costs are reduced significantly This is another part that is until Phone 7 is out difficult to judge It is a part that I believe stems from an underlying error OEMs add code to differentiate and to push branded apps and services not because they have to compensate for an OS missing functionality especially now with Android 2 2 Android 1 5 and 1 6 needed some addition from third parties because of lack of features Carriers once sold a device are not that interested in providing updates

  • On WebM again: freedom, quality, patents « carlodaffara.conecta.itcarlodaffara.conecta.it
    a convenient licensing alternative to everyone on the same terms and to include as much essential intellectual property as possible for their convenience Participation in the License is voluntary on the part of essential patent holders however So if someone claims that you infringe on its patent claiming that you licensed it from MPEG LA is not a defense And just to provide an example in the Microsoft vs Alcatel Lucent case MS had to fight quite a long time to have the claim dismissed after an initial 1 52B damages decision In a previous effort for creating an open video codec by Sun Microsystem Sun similarly did not introduce a patent indemnification clause in it in fact in one of the OMV presentations this text was included While we are encouraged by our findings so far the investigation continues and Sun and OMC cannot make any representations regarding encumbrances or the validity or invalidity of any patent claims or other intellectual property rights claims a third party may assert in connection with any OMC project or work product So after all this text I think that there may be some more complexity behind Google s decision to drop H264 than we want to kill Apple as some commenters seem to think and the final line is software patents are adding a degree of complexity to the ICT world that is becoming in my humble opinion damaging in too many ways not only in terms of uncertainty but adding a great friction in the capability of companies and researchers to bring innovation to the market Something that curiously patent promoters describe as their first motivation This entry was posted on Wednesday January 19th 2011 9 53 am and is filed under Uncategorized You can follow any responses to this entry through RSS 2 0 You can leave a response or trackback from your own site Comments 16 Trackbacks 24 1 by antimatter15 February 2nd 2011 at 00 01 Great article But chromium never had support for h 264 or mp3 for that matter Quote 2 by Greg February 2nd 2011 at 08 14 Stop spoiling it for everyone The Google is sticking it to Apple story is much more entertaining than the prosaic facts Quote 3 by El Lizardo February 2nd 2011 at 08 30 Sincere question how will WebM improve over time in terms of quality and feature set without infringing on all those patents Quote 4 by cdaffara February 2nd 2011 at 09 16 That s a very good question a problem of the current patent environment is that there are not only the H264 patents to avoid but an entire minefield that is extremely hard to travel unscathed My own belief is that improvements are possible in two areas preprocessing of video material to make it easier to process things like film grain separation and iterative encoding that used non psycho visual measures to direct bit allocation At the moment WebM is roughly equivalentto a good H264 encoder and in the lower league of x264 that is absolutely the best in the market Overall it is good enough to be competitive quality wise the biggest problem is encoding speed that is abysmal well probably not that bad but certainly too slow On that I believe that it is possible to improve substantially without infringing patents Quote 5 by cdaffara February 2nd 2011 at 09 16 Ah But I am trying to spoil fun for everyone Despicable me Quote 6 by cdaffara February 2nd 2011 at 09 17 Yes it is Chrome that embeds native mp3 and H264 support thanks to a license obtained from MPEGLA Quote 7 by Andy February 2nd 2011 at 18 29 Let s hope John Gruber of Daring Fireball reads this Quote 8 by Arturo February 2nd 2011 at 20 41 Quoting Considering that most H264 players are limited to the baseline H264 profile we can safely say that WebM is or can be on the same quality level of H264 But isn t the graph saying the opposite with VP8 best on par with x264 worst Am i misinterpreting the graph Or is it assumed that the bitrates used for HTML5 video will be around 500kbps where VP8 best matches x264 normal Quote 9 by Tim F February 3rd 2011 at 03 15 The mostly just baseline myth doesn t work anymore the vast majority of smartphones made over the last few years easily support main profile up to 720p at 30fps Quote 10 by Jason IANAL February 3rd 2011 at 03 27 The advantage of MPEG LA over Google is that patent holders have a choice to join a patent pool that would advance their mutual interests If a patent holder knows about a patent pool but chooses not to inform the pool of their patent it could be found as an indication that they waive their right to enforce their patent e g Qualcomm v Broadcom 2008 The members of a patent pool would also have a common interest in protecting their patents against a patent holder outside the pool Therefore the patent risk is lower with H 264 than VP8 Quote 11 by cdaffara February 3rd 2011 at 08 36 The problem may be more complex than that In the Alcatel MS trial the existence of additional patents was not found to be an automatic waiver a fact that is also part of Qualcomm vs Broadcom the waiver was decided because when a witness for Qualcomm in a patent dispute admitted that she had received e mails from a mailing list called the avc ce list which was evidence of Qualcomm s participation in a standards setting body called JVT on the H 2264 standard before a specific point in time In the Court s words Qualcomm s assertion that it had not participated in the JVT was vital to its success in defeating Broadcom s waiver argument http allaboutinformation ca 2008 01 09 more on qualcomm v broadcom

    That s the difference not price that may be lower or not as RedHat demonstrates it is competition on value and speed of change Ah by the way SugarCRM despite being a nice company with a nice CEO is not 100 open source since that by definition would mean that all code and all releases are under a 100 open source license and this is not the case As I mentioned before I am not against open core or whatever model a company wants to use especially if it works for them like the case of SugarCRM My observation is that we must be careful how we handle words or those words start to lose their value as bearers of meaning This entry was posted on Monday December 6th 2010 10 15 am and is filed under Uncategorized You can follow any responses to this entry through RSS 2 0 You can leave a response or trackback from your own site Comments 4 Trackbacks 2 1 by Charles Tryon December 6th 2010 at 23 34 I m not saying that I agree with RMS on this point but since you mentioned his name I should point out that he has long had a gripe with the Open Source value of as you say a way to allow for far faster development and improvement of a product RMS has long emphasized the intrinsic value of real freedom in software as a guarantee that I can use the software as I see fit that I can improve it in any way I like regardless of whether or not someone else is interested in my changes and I can pass those changes along to anyone I want and by extension they will have the same freedoms as I have The fact that this ends up being a more energized development environment is a side effect of the fact that the software has been set free Again I m not disagreeing with you Just clarifying a point on RMS Thanks Quote 2 by cdaffara December 7th 2010 at 08 17 Dear Charles many thanks for your comment I know that RMS has always valued freedom more than any supposed Open Source development advantage and I agree with you that he sees it only as a nice side effect In our research I have however voluntarily decided to avoid any philosophical or political background and focus on the aspects that do have a direct impact on the economic potential of FLOSS So in this sense freedom has a substantial economic value as it does collaborative development You are right in pointing out that my presentation of RMS views is simplistic but I still have qualms with the choice of free as the defining word given the ease with which it can be turned into something different Thanks again Carlo Daffara Quote 3 by twitter December 8th 2010 at 19 10 Thanks for noticing this but why do you blame RMS for Microsoft s dishonesty and
