  • Comparing companies effectiveness: a response to Savio Rodrigues « carlodaffara.conecta.itcarlodaffara.conecta.it
    to other public companies in the same sector he would have found that most of them are nearly identical in R D versus SG A costs when compared within the same class in terms of market capitalisation In fact only startups that rarely can go to the stock market have an higher than average R D Other companies with similar properties are companies in the biochemistry and drug design firms that have a long incubation period to create a product and for this reason have a high R D share Then the balance sheet is in itself not a good way to measure the productivity or savings in development compared to same class companies In fact as I wrote some days ago savings due to the adoption of OSS are not inherently visible in balance sheets but appear as better quality product or as the capability of producing goods at a lower price point In fact just thinking of comparing RedHat with a company that is 55 times larger should provide an idea of how big an advantage is OSS in terms of efficiency Many companies are helped by the existence of a trialable product and in this sense there may be a core of truth in the idea that cost for customer acquisition may be lower I am not convinced that cost reduction is so significant at least not to the same extent of R D advantages that are clearly easier to measure and that tend to be significant I agree with Savio that competition should not happen exclusively on pricing but it may be a part of a larger strategy but I contend that by looking just at two balance sheet breackdowns can give us information on whether OSS is more or less efficient in terms of product creation I continue to believe that in many markets OSS provides a substantial advantage after all Rishab et al estimated the average R D advantage at 36 my estimates are from 20 to 75 in specific industrial areas but in any case substantial update Savio added another company Tibco which is similar to RedHat size as before it shows very similar results It is my belief that even adding additional companies will more or less show that for software intensive companies the results will be more or less the same I also believe that the real comparison should happen outside the financial sheets by comparing the market in which markets do the company compete What is the average size of the competitors If we can show that on average OSS companies tend to be efficient competitors in markets much larger than their own then we can show that OSS can give an advantage If Rishab s evaluation is right the 36 increased efficiency should bring the equivalent of a capital advantage of 50 roughly so we should check whether RedHat or Alfresco effectively compete with companies that are at least 50 larger than themselves This entry was posted on Monday

  • The dynamics of OSS adoptions, II - diffusion processes « carlodaffara.conecta.itcarlodaffara.conecta.it
    choosing one technology over the other depends on several factors a very good model for such adoption is the UTAUT model some pdf examples here and here that was found capable of predicting 70 of the variance of adoption success what it means that the parameters in the model explain nearly perfectly whether you will adopt a technology or not The important point to remember this is about individual adoption not mandated and without external constraints In this sense we can use it to predict how a PC owner chooses her web browser or how a small company may choose which web server to use The model uses four parameters performance expectancy effort expectancy social influence and facilitating conditions performance expectancy The degree to which a person believes that using a particular system would enhance his or her job performance or the degree to which using an innovation is perceived as being better than using its precursor effort expectancy the degree to which a person believes that using a system would be free of effort or the degree to which a system is perceived as relatively difficult to understand and use social influence The individual s internalization of the reference group s subjective culture and specific interpersonal agreements that the individual has made with others in specific social situations or the degree to which use of an innovation is perceived to enhance one s image or status in one s social system facilitating conditions Reflects perceptions of internal and external constraints on behaviour and encompasses self efficacy resource facilitating conditions and technology facilitating conditions or objective factors in the environment that observers agree make an act easy to do including the provision of computer support In the next post I will present an example of these four parameters in the

  • Oracle/Google: the patents and the implications « carlodaffara.conecta.itcarlodaffara.conecta.it
    contributors to the Linux kernel That is something that will be very difficult to recover Second Google now has a free quite important gift the attention has been moved from their recent net neutrality blunder and they are again the David of the situation I could not imagine a better gift Third with this lawsuit Oracle basically announced the world that Java in mobile is dead This was actually something that most people already knew but seeing it in writing is always reassuring Update Miguel de Icaza claims that The Java specification patent grant patent grant seems to be only valid as long as you have a fully conformant implementation but that applies only to the Standard Implementation of Java not OpenJDK Sorry Miguel nice try More luck next time Update 2 cleaned the language on the phrase on patents ideas and implementation that was badly worded ù Update 3 clarified the Dalvik OpenJDK idea FLOSS open source software patents This entry was posted on Friday August 13th 2010 8 27 am and is filed under blog divertissements You can follow any responses to this entry through RSS 2 0 You can leave a response or trackback from your own site Comments 14 Trackbacks 20 1 by Andreas Kuckartz August 13th 2010 at 11 59 Can you please substantiate the statement that distributing the GPL2 binaries without linking and using them will transfer patent protection Quote 2 by cdaffara August 13th 2010 at 12 57 It was quite badly worded The point is that by releasing OpenJDK under the GPL2 Sun granted an implicit IPR license for its relevant patents as such any combined artefact that is derived from the OpenJDK code will get the same kind of protection I have changed the wording in the text as well to make it clearer by the way I think that the patents are quite weak on their own at least the first three that I read through I doubt that they will stand to a deeper scrutiny Quote 3 by Vuk August 13th 2010 at 16 30 Not a big deal though but it s not SPSS v WPS it s SAS v WPS Quote 4 by steve August 13th 2010 at 19 06 Google does not use the OpenJDK libraries It uses the ones from Apache Harmony And Dalvik is basically derived from Apache s implementation of the VM too So Oracle basically says that the Apache foundation which is the creator of some of the most important Java libraries servers frameworks stole from them Quote 5 by Tom August 13th 2010 at 19 09 Related This is truly a perversion of the open source spirit After 4 years of contributing to OpenSolaris his code flies by http sstallion blogspot com 2010 08 opensolaris is dead html Quote 6 by Matt August 13th 2010 at 21 57 questionable patents hmm Quote 7 by Nadav August 14th 2010 at 08 31 From a high level point of view I think that

  • OSS: the real point is software control « carlodaffara.conecta.itcarlodaffara.conecta.it
    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 compensated by the features you get which is reasonable or what kind of risk are you accepting in exchange You like the integrated set of features proposed by Microsoft That s good as long as you know that some of the actions that they did in the past were not exactly transparent and that your control of their offering is very limited You like Google Good Just understand what happens if Gmail does not work You prefer open source Good But with the increased control you get with it you also get responsibility and increased effort
