    CEO should decide what is more important so the decision is not ethical but practical and based on economics You will never get the kind of participation that Linux Apache and Eclipse do have in an Open Core model If that is ok for you that s great The fact that most VC are funding open core companies is just a data point Lots of open source companies do well without VC funding It is true that lots of people claims that pure open source models are not sustainable Even my friend Erwin Tenhumberg that is quite knowledgeable expert and incredibly nice on its own had a slide in this sense in his LinuxTag presentation and you can find lots of comments like that in many publication something like the majority of OSS companies adopt the so called mixed model despite this being actually false as we found in our survey of OSS companies The point like said before is that the important thing is not that there is a superior model but that for every company every market there is an optimal model it may be OC it may be pure services or lots of combinations of our 11 building blocks The optimal model changes with time and market condition and what is appropriate now may be wrong tomorrow No open source model can achieve the kind of profit margins of proprietary companies So if you want to make your OSS company remember this basic fact If you want the kind of profit margins of Microsoft or Oracle forget it So to end this post there are three critical points whether the model is clear for the adopter and this should be a given and actually nowadays I would say that most companies are absolutely honest and clear on this whether the software in its open source edition provides sufficient functionality to be useful to a wide range of adopters and this is a fine line to walk and requires constant adaptation and whether the increased monetization compensates for the lack of external contributions that can substantially increase the value of the code base you are trading cash for code and engineering in a sense Can we put this to rest End the name calling be friends and call all of us family Especially since right now under the sun of Fuerteventura where I am writing this it seems difficult to fight by the way sorry for any misspelling There is no spell checker here on this small screen open source OSS business models 6 Comments On WebM H264 and FFmpeg implementation Posted by cdaffara in blog divertissements on July 6th 2010 I was recently reminded by Gregory Maxwell of Xiph about the new non Google implementation of VP8 done within the context of FFmpeg and many commenters on Slashdot observed that the fact that the implementation shares lots of code with the H264 part is further demonstration that VP8 is infriging on MPEG LA held patents Actually there

    to Eucalyptus because that would have undermined the capability of the company to make users pay for the enterprise edition I already wrote in the past that Open Core is not evil per se but that it does introduce difficulties in encouraging external participation both because there is a very thin line in feature selection between the community and enterprise edition and because open core naturally hampers participation I had some readers asking me why and I will respond with a subset of my LinuxTag slides Open core is usually built by a set of internal open source components held together by a dual licensed wrapper plus proprietary modules on the outside One of the best examples of this is Zimbra an excellent product on its own but MySQL in recent editions can be included in the same group As discussed in previous posts dual licensing hampers contributions because it requires an explicit agreement on ceding rights to the company that employs it in order to be able to relicense it for the proprietary edition This means that Open Core companies in itself will have an easier time in monetizing their software but will receive much less contributions in exchange As I wrote before it is simply not possible to get something like Linux or Apache with Open Core Again open core is not bad per se but I would have been more cautious in calling Sugar an open source company for whatever definition you have of that But it is a tradeoff monetization versus contributions And my bets are on contributions as OpenStack demonstrates you need leverage and external resources to go beyond what a single company can do open source OSS adoption OSS business models 5 Comments You are currently browsing the archives for Wednesday July 21st 2010

    entity through a contract or legal transaction Efficiency is the ability to perform an action with a lower cost both tangible and intangible and is something that follows the specialization in a work area or appears thanks to a new technology Examples of the first are simply the decrease in time necessary to perform an action when you increase your expertise in it the first time you install a complex system may require lots of effort and this effort is reduced the more you experience the tasks necessary to perform the installation itself Examples of the second may be the introduction of a tool that simplifies the process for example through image cloning and it introduces a huge discontinuity a jump in the graph of efficiency versus time These two aspects are the basis of all the business models that we have analysed in the past it is possible to show that all of them fall in a continuum between properties and efficiency Among the results of our past research project one thing that we found is that property based projects tend to have lower contributions from the outside because it requires a legal transaction to become part of the company s properties think for example at dual licensing to become part of the product source code an external contributor needs to sign off his rights to the code to allow the company to sell the enterprise version alongside the open one On the other hand right handed models based purely on efficiency tends to have higher contributions and visibility but lower monetization rates As I wrote many times there is no ideal business model but a spectrum of possible models and companies should adapt themselves to changing market conditions and adapt their model as well Some companies start as
