Steve Langasek: SecureBoot in Ubuntu 12.10

The 12.10 release is the first version of Ubuntu that supports Secure Boot out of the box. In what is largely an accident of release timing, from what I can tell (and please correct me if I'm wrong), this actually makes Ubuntu 12.10 the first general release of any OS to support Secure Boot. (Windows 8 of course is also now available; and I'm sure Matthew Garrett, who has been a welcome collaborator throughout this process, has everything in good order for the upcoming Fedora 18 release.) That's certainly something of a bittersweet achievement. I'm proud of the work we've done to ensure Ubuntu will continue to work out of the box on the consumer hardware of the future; in spite of the predictable accusations on the blogowebs that we've sold out, I sleep well at night knowing that this was the pragmatic decision to make, maximizing users' freedom to use their hardware. All the same, I worry about what the landscape is going to look like in a few years' time. The Ubuntu first-stage EFI bootloader is signed by Microsoft, but the key that is used for signing is one that's recommended by Microsoft, not one that's required by the Windows 8 certification requirements. Will all hardware include this key in practice? The Windows 8 requirements also say that every machine must allow the user to disable Secure Boot. Will manufacturers get this right, and will users be able to make use of it in the event the manufacture didn't include the Microsoft-recommended key? Only time will tell. But I do think the Linux community is going to have to remain engaged on this for some time to come, and possibly hold OEMs' feet to the fire for shipping hardware that will only work with Windows 8. But that's for the future. For now, we have a technical solution in 12.10 that solves the parts of the problem that we can solve. This first release gives us preliminary support for booting on Secure Boot, but there's more work to be done to provide a full solution that's sustainable over the long term. We'll be discussing some of that this week at UDS in Copenhagen. And as part of our committment to enabling new hardware on the current LTS release, we will be backporting this work for inclusion in 12.04.2. It remains to be decided how Debian will approach the Secure Boot question. At DebConf 12, many people seemed to consider it a foregone conclusion that Debian would never agree to include binaries in main signed by third-party keys. I don't think that should be a given; I think allowing third-party signatures in main for hardware compatibility is consistent with Debian's principles, and refusing to make Debian compatible with this hardware out of the box does nothing to advance user freedom. I hope to see frank discussion post-wheezy about keeping Debian relevant on consumer hardware of the future.

Gunnar Wolf: Cycling: Atzcapozalco's cycle path; @p00k4 sends me rail-riding!

Yesterday I went to FES Iztacala, the faculty where I worked between 1999 and 2003. It's nice to go visit some good friends (even if to talk for work issues). It is somewhat far from my usual roaming area (~25Km straight to the North), so I cannot do it as often as I'd like. But anyway - I had to be at work early in the morning, but leaving from here a bit early for lunchtime, and leaving home at ~14:30, I managed to arrive to Iztacala in ~75 minutes. Sustained cycling for 20 Km/h, even counting stops at traffic lights on the way, yay! Anyway, had a productive and fun evening there, but around 18:00 I decided to head back before night got me Specially for the first part of the way, as I'm not familiar with Atzcapozalco. Alejandro suggested me to go by the recently (some months ago) opened cycle path that covers 4Km and almost exactly crosses the delegation (each of the 16 constitutive parts of Distrito Federal, where an important part of Mexico City is located). The cycle path is a good initiative... But I must say, I'm very very glad I took it still with good daylight. As well as the Recreative cyclepath that goes to the South, until the border of Morelos state, this one was built over abandoned rail tracks. Good use for a vacant and useless public space Rail tracks which lay unclaimed in the city are uncomfortable to walk, and useless for anything else, so they basically mean a useless 2m-wide strip of common grounds. So, I welcome any initiatives that make it into a useful space again! And two meters are just enough for a comfortable cycling path - Yes, which will surely be shared with pedestrians, and sometimes becomes uncomfortable. But lets try it! However... When rail tracks are decomissioned and cycle paths built over them... the metal should be dismounted! Not only because of economic concerns (good metal used for rail tracks is much more expensive and useful than asphalt), but because if it stays there, it just becomes a danger. Specially, as is the case, if the asphalt is just deep enough to sometimes cover the tracks And sometimes not. Had I known, I would have taken several photographs of important mistakes in the rail layout. I know I was very close to having an accident at least once (this means, I lost balance and miraclously managed to slow down from ~15Km/h by running with the bike between my legs!), and got in uncomfortable situations several more times. For a good portion of the track, there is a train track running at about of its width, so I had to constantly ring the bell or shout whenever I saw pedestrians As changing from side to side to route around them would put both them and me in danger. Towards the Southern part of the cycle path, as it is a much more active industrial area, there are many places where multiple tracks cross each other under the thin asphalt, sometimes completely unpaved. In one of those points I even decided to step down of the bike and make ~20m walking. This cycle path seems like it was done in a great hurry to present a successful project to the Politicians in Charge, without much thought on what it requires to be really a good project. It provides, yes, a very useful and good mobility solution for cyclists in the North-West. But it is too dangerous... And I am not sure whether I'd take it again. Probably not. So, all in all... Oh, and lastly: Some might be surprised I'm using bits of Twitterspeak here. But well, I now have presence a bot repeating my posts over there, so I'd better get Alejandro to read this using the proper channels ;-)

Julien Danjou: Ceilometer, the OpenStack metering project

For the last months, I've been working on a metering project for OpenStack, so it's time to talk a bit about it. OpenStack is a growing cloud platform providing IaaS. A problem easily identified by everyone building a public cloud platform is that nothing is provided to retrieve the platform usage data. Some data are available in some places, but not everything is, and you have to do a lot of processing from the various components to get something useful in the end. But in order to bill customers that are using your public cloud platform, you need to dot his. In this regard, a lot of companies running public OpenStack based infrastructure wrote their own solution to cover this functional areas, and to become able to bill theirs customers. To avoid everybody doing and maintaining such a stack in their corners, the Ceilometer has been created. The project aims to cover the metering aspect of the OpenStack components, pulling usage data from every components and storing them into a single place. It then offer a retrieving point for this data via a REST API. The initial specifications have been written in April this year, and actual implementation started in May. The project is currently worked on by me, Dreamhost and Canonical. We already have designed an architecture that we are implementing, and we hope to release a first usable version with Folsom. Ceilometer architecture I did a presentation of this project yesterday at XLCloud, which has been very well received. <iframe allowfullscreen="true" frameborder="0" height="389" mozallowfullscreen="true" src="https://docs.google.com/presentation/embed?id=11ALGC4xuWcRvXKTSnnsteJUkArsTfQW-7IAfWRRI5kQ&amp;start=false&amp;loop=false&amp;delayms=3000" webkitallowfullscreen="true" width="480"></iframe> If you are interested in helping us and contributing, feel free to join us during one of our weekly IRC meeting or fix some bugs. :-)

Christian Perrier: So, what happened with Kikithon?

I mentioned this briefly yesterday, but now I'll try to summarize the story of a great surprise and a big moment for me. All this started when my wife Elizabeth and my son Jean-Baptiste wanted to do something special for my 50th birthday. So, it indeed all started months ago, probably early March or something (I don't yet have all the details). Jean-Baptiste described this well on the web site, so I won't go again into details, but basically, this was about getting birthday wishes from my "free software family" in, as you might guess, as many languages as possible. Elizabeth brought the original idea and JB helped her by setting up the website and collecting e-mail addresses of people I usually work with: he grabbed addresses from PO files on Debian website, plus some in his own set of GPG signatures and here we go. And then he started poking dozens of you folks in order to get your wishes for this birthday. Gradually, contributions accumulated on the website, with many challenges for them: be sure to get as many people as possible, poking and re-poking all those FLOSS people who keep forgetting things... It seems that poking people is something that's probably in the Perrier's genes! And they were doing all this without me noticing. As usually in Debian, releasing on time is a no-no. So, it quickly turned out that having everything ready by April 2nd wouldn't be possible. So, their new goal was offering this to me on Pentecost Sunday, which was yesterday. And...here comes the gift. Aha, this looks like a photo album. Could it be a "50 years of Christian" album? But, EH, why is that pic of me, with the red Debconf5 tee-shirt (that features a world map) and a "bubulle" sign, in front of the book? But, EH EH EH, what the .... are doing these word by H0lger, then Fil, then Joey doing on the following pages? And only then, OMG, I discover the real gift they prepared. 106, often bilingual, wishes from 110 people (some were couples!). 18 postcards (one made of wood). 45 languages. One postcard with wishes from nearly every distro representatives at LinuxTag 2011. Dozens of photos from my friends all around the world. All this in a wonderful album. I can't tell what I said. Anyway, JB was shooting a video, so...we'll see. OK, I didn't cry...but it wasn't that far and emotion was really really intense. Guys, ladies, gentlemen, friends....it took me a while to realize what you contributed to. It took me the entire afternoon to realize the investment put by Elizabeth and JB (and JB's sisters support) into this. Yes, as many of you wrote, I have an awesome family and they really know how to share their love. I also have an awesome virtual family all around the world. Your words are wholeheartedly appreciated and some were indeed much much much appreciated. Of course, I'll have the book in Banja Luka so that you can see the result. I know (because JB and Elizabeth told me) that many of you were really awaiting to see how it would be received (yes, that includes you, in Germany, who I visited in early May!!!).

Petter Reinholdtsen: The reply from Edgar Villanueva to Microsoft in Peru

A few days ago an article in the Norwegian Computerworld magazine about how version 2.0 of European Interoperability Framework has been successfully lobbied by the proprietary software industry to remove the focus on free software. Nothing very surprising there, given earlier reports on how Microsoft and others have stacked the committees in this work. But I find this very sad. The definition of an open standard from version 1 was very good, and something I believe should be used also in the future, alongside the definition from Digistan. Version 2 have removed the open standard definition from its content. Anyway, the news reminded me of the great reply sent by Dr. Edgar Villanueva, congressman in Peru at the time, to Microsoft as a reply to Microsofts attack on his proposal regarding the use of free software in the public sector in Peru. As the text was not available from a few of the URLs where it used to be available, I copy it here from my source to ensure it is available also in the future. Some background information about that story is available in an article from Linux Journal in 2002.
Lima, 8th of April, 2002
To: Se or JUAN ALBERTO GONZ LEZ
General Manager of Microsoft Per Dear Sir: First of all, I thank you for your letter of March 25, 2002 in which you state the official position of Microsoft relative to Bill Number 1609, Free Software in Public Administration, which is indubitably inspired by the desire for Peru to find a suitable place in the global technological context. In the same spirit, and convinced that we will find the best solutions through an exchange of clear and open ideas, I will take this opportunity to reply to the commentaries included in your letter. While acknowledging that opinions such as yours constitute a significant contribution, it would have been even more worthwhile for me if, rather than formulating objections of a general nature (which we will analyze in detail later) you had gathered solid arguments for the advantages that proprietary software could bring to the Peruvian State, and to its citizens in general, since this would have allowed a more enlightening exchange in respect of each of our positions. With the aim of creating an orderly debate, we will assume that what you call "open source software" is what the Bill defines as "free software", since there exists software for which the source code is distributed together with the program, but which does not fall within the definition established by the Bill; and that what you call "commercial software" is what the Bill defines as "proprietary" or "unfree", given that there exists free software which is sold in the market for a price like any other good or service. It is also necessary to make it clear that the aim of the Bill we are discussing is not directly related to the amount of direct savings that can by made by using free software in state institutions. That is in any case a marginal aggregate value, but in no way is it the chief focus of the Bill. The basic principles which inspire the Bill are linked to the basic guarantees of a state of law, such as:
  • Free access to public information by the citizen.
  • Permanence of public data.
  • Security of the State and citizens.
To guarantee the free access of citizens to public information, it is indispensable that the encoding of data is not tied to a single provider. The use of standard and open formats gives a guarantee of this free access, if necessary through the creation of compatible free software. To guarantee the permanence of public data, it is necessary that the usability and maintenance of the software does not depend on the goodwill of the suppliers, or on the monopoly conditions imposed by them. For this reason the State needs systems the development of which can be guaranteed due to the availability of the source code. To guarantee national security or the security of the State, it is indispensable to be able to rely on systems without elements which allow control from a distance or the undesired transmission of information to third parties. Systems with source code freely accessible to the public are required to allow their inspection by the State itself, by the citizens, and by a large number of independent experts throughout the world. Our proposal brings further security, since the knowledge of the source code will eliminate the growing number of programs with *spy code*. In the same way, our proposal strengthens the security of the citizens, both in their role as legitimate owners of information managed by the state, and in their role as consumers. In this second case, by allowing the growth of a widespread availability of free software not containing *spy code* able to put at risk privacy and individual freedoms. In this sense, the Bill is limited to establishing the conditions under which the state bodies will obtain software in the future, that is, in a way compatible with these basic principles. From reading the Bill it will be clear that once passed:
  • the law does not forbid the production of proprietary software
  • the law does not forbid the sale of proprietary software
  • the law does not specify which concrete software to use
  • the law does not dictate the supplier from whom software will be bought
  • the law does not limit the terms under which a software product can be licensed.
  • What the Bill does express clearly, is that, for software to be acceptable for the state it is not enough that it is technically capable of fulfilling a task, but that further the contractual conditions must satisfy a series of requirements regarding the license, without which the State cannot guarantee the citizen adequate processing of his data, watching over its integrity, confidentiality, and accessibility throughout time, as these are very critical aspects for its normal functioning. We agree, Mr. Gonzalez, that information and communication technology have a significant impact on the quality of life of the citizens (whether it be positive or negative). We surely also agree that the basic values I have pointed out above are fundamental in a democratic state like Peru. So we are very interested to know of any other way of guaranteeing these principles, other than through the use of free software in the terms defined by the Bill. As for the observations you have made, we will now go on to analyze them in detail: Firstly, you point out that: "1. The bill makes it compulsory for all public bodies to use only free software, that is to say open source software, which breaches the principles of equality before the law, that of non-discrimination and the right of free private enterprise, freedom of industry and of contract, protected by the constitution." This understanding is in error. The Bill in no way affects the rights you list; it limits itself entirely to establishing conditions for the use of software on the part of state institutions, without in any way meddling in private sector transactions. It is a well established principle that the State does not enjoy the wide spectrum of contractual freedom of the private sector, as it is limited in its actions precisely by the requirement for transparency of public acts; and in this sense, the preservation of the greater common interest must prevail when legislating on the matter. The Bill protects equality under the law, since no natural or legal person is excluded from the right of offering these goods to the State under the conditions defined in the Bill and without more limitations than those established by the Law of State Contracts and Purchasing (T.U.O. by Supreme Decree No. 012-2001-PCM). The Bill does not introduce any discrimination whatever, since it only establishes *how* the goods have to be provided (which is a state power) and not *who* has to provide them (which would effectively be discriminatory, if restrictions based on national origin, race religion, ideology, sexual preference etc. were imposed). On the contrary, the Bill is decidedly antidiscriminatory. This is so because by defining with no room for doubt the conditions for the provision of software, it prevents state bodies from using software which has a license including discriminatory conditions. It should be obvious from the preceding two paragraphs that the Bill does not harm free private enterprise, since the latter can always choose under what conditions it will produce software; some of these will be acceptable to the State, and others will not be since they contradict the guarantee of the basic principles listed above. This free initiative is of course compatible with the freedom of industry and freedom of contract (in the limited form in which the State can exercise the latter). Any private subject can produce software under the conditions which the State requires, or can refrain from doing so. Nobody is forced to adopt a model of production, but if they wish to provide software to the State, they must provide the mechanisms which guarantee the basic principles, and which are those described in the Bill. By way of an example: nothing in the text of the Bill would prevent your company offering the State bodies an office "suite", under the conditions defined in the Bill and setting the price that you consider satisfactory. If you did not, it would not be due to restrictions imposed by the law, but to business decisions relative to the method of commercializing your products, decisions with which the State is not involved. To continue; you note that:" 2. The bill, by making the use of open source software compulsory, would establish discriminatory and non competitive practices in the contracting and purchasing by public bodies..." This statement is just a reiteration of the previous one, and so the response can be found above. However, let us concern ourselves for a moment with your comment regarding "non-competitive ... practices." Of course, in defining any kind of purchase, the buyer sets conditions which relate to the proposed use of the good or service. From the start, this excludes certain manufacturers from the possibility of competing, but does not exclude them "a priori", but rather based on a series of principles determined by the autonomous will of the purchaser, and so the process takes place in conformance with the law. And in the Bill it is established that *no one* is excluded from competing as far as he guarantees the fulfillment of the basic principles. Furthermore, the Bill *stimulates* competition, since it tends to generate a supply of software with better conditions of usability, and to better existing work, in a model of continuous improvement. On the other hand, the central aspect of competivity is the chance to provide better choices to the consumer. Now, it is impossible to ignore the fact that marketing does not play a neutral role when the product is offered on the market (since accepting the opposite would lead one to suppose that firms' expenses in marketing lack any sense), and that therefore a significant expense under this heading can influence the decisions of the purchaser. This influence of marketing is in large measure reduced by the bill that we are backing, since the choice within the framework proposed is based on the *technical merits* of the product and not on the effort put into commercialization by the producer; in this sense, competitiveness is increased, since the smallest software producer can compete on equal terms with the most powerful corporations. It is necessary to stress that there is no position more anti-competitive than that of the big software producers, which frequently abuse their dominant position, since in innumerable cases they propose as a solution to problems raised by users: "update your software to the new version" (at the user's expense, naturally); furthermore, it is common to find arbitrary cessation of technical help for products, which, in the provider's judgment alone, are "old"; and so, to receive any kind of technical assistance, the user finds himself forced to migrate to new versions (with non-trivial costs, especially as changes in hardware platform are often involved). And as the whole infrastructure is based on proprietary data formats, the user stays "trapped" in the need to continue using products from the same supplier, or to make the huge effort to change to another environment (probably also proprietary). You add: "3. So, by compelling the State to favor a business model based entirely on open source, the bill would only discourage the local and international manufacturing companies, which are the ones which really undertake important expenditures, create a significant number of direct and indirect jobs, as well as contributing to the GNP, as opposed to a model of open source software which tends to have an ever weaker economic impact, since it mainly creates jobs in the service sector." I do not agree with your statement. Partly because of what you yourself point out in paragraph 6 of your letter, regarding the relative weight of services in the context of software use. This contradiction alone would invalidate your position. The service model, adopted by a large number of companies in the software industry, is much larger in economic terms, and with a tendency to increase, than the licensing of programs. On the other hand, the private sector of the economy has the widest possible freedom to choose the economic model which best suits its interests, even if this freedom of choice is often obscured subliminally by the disproportionate expenditure on marketing by the producers of proprietary software. In addition, a reading of your opinion would lead to the conclusion that the State market is crucial and essential for the proprietary software industry, to such a point that the choice made by the State in this bill would completely eliminate the market for these firms. If that is true, we can deduce that the State must be subsidizing the proprietary software industry. In the unlikely event that this were true, the State would have the right to apply the subsidies in the area it considered of greatest social value; it is undeniable, in this improbable hypothesis, that if the State decided to subsidize software, it would have to do so choosing the free over the proprietary, considering its social effect and the rational use of taxpayers money. In respect of the jobs generated by proprietary software in countries like ours, these mainly concern technical tasks of little aggregate value; at the local level, the technicians who provide support for proprietary software produced by transnational companies do not have the possibility of fixing bugs, not necessarily for lack of technical capability or of talent, but because they do not have access to the source code to fix it. With free software one creates more technically qualified employment and a framework of free competence where success is only tied to the ability to offer good technical support and quality of service, one stimulates the market, and one increases the shared fund of knowledge, opening up alternatives to generate services of greater total value and a higher quality level, to the benefit of all involved: producers, service organizations, and consumers. It is a common phenomenon in developing countries that local software industries obtain the majority of their takings in the service sector, or in the creation of "ad hoc" software. Therefore, any negative impact that the application of the Bill might have in this sector will be more than compensated by a growth in demand for services (as long as these are carried out to high quality standards). If the transnational software companies decide not to compete under these new rules of the game, it is likely that they will undergo some decrease in takings in terms of payment for licenses; however, considering that these firms continue to allege that much of the software used by the State has been illegally copied, one can see that the impact will not be very serious. Certainly, in any case their fortune will be determined by market laws, changes in which cannot be avoided; many firms traditionally associated with proprietary software have already set out on the road (supported by copious expense) of providing services associated with free software, which shows that the models are not mutually exclusive. With this bill the State is deciding that it needs to preserve certain fundamental values. And it is deciding this based on its sovereign power, without affecting any of the constitutional guarantees. If these values could be guaranteed without having to choose a particular economic model, the effects of the law would be even more beneficial. In any case, it should be clear that the State does not choose an economic model; if it happens that there only exists one economic model capable of providing software which provides the basic guarantee of these principles, this is because of historical circumstances, not because of an arbitrary choice of a given model. Your letter continues: "4. The bill imposes the use of open source software without considering the dangers that this can bring from the point of view of security, guarantee, and possible violation of the intellectual property rights of third parties." Alluding in an abstract way to "the dangers this can bring", without specifically mentioning a single one of these supposed dangers, shows at the least some lack of knowledge of the topic. So, allow me to enlighten you on these points. On security: National security has already been mentioned in general terms in the initial discussion of the basic principles of the bill. In more specific terms, relative to the security of the software itself, it is well known that all software (whether proprietary or free) contains errors or "bugs" (in programmers' slang). But it is also well known that the bugs in free software are fewer, and are fixed much more quickly, than in proprietary software. It is not in vain that numerous public bodies responsible for the IT security of state systems in developed countries require the use of free software for the same conditions of security and efficiency. What is impossible to prove is that proprietary software is more secure than free, without the public and open inspection of the scientific community and users in general. This demonstration is impossible because the model of proprietary software itself prevents this analysis, so that any guarantee of security is based only on promises of good intentions (biased, by any reckoning) made by the producer itself, or its contractors. It should be remembered that in many cases, the licensing conditions include Non-Disclosure clauses which prevent the user from publicly revealing security flaws found in the licensed proprietary product. In respect of the guarantee: As you know perfectly well, or could find out by reading the "End User License Agreement" of the products you license, in the great majority of cases the guarantees are limited to replacement of the storage medium in case of defects, but in no case is compensation given for direct or indirect damages, loss of profits, etc... If as a result of a security bug in one of your products, not fixed in time by yourselves, an attacker managed to compromise crucial State systems, what guarantees, reparations and compensation would your company make in accordance with your licensing conditions? The guarantees of proprietary software, inasmuch as programs are delivered AS IS'', that is, in the state in which they are, with no additional responsibility of the provider in respect of function, in no way differ from those normal with free software. On Intellectual Property: Questions of intellectual property fall outside the scope of this bill, since they are covered by specific other laws. The model of free software in no way implies ignorance of these laws, and in fact the great majority of free software is covered by copyright. In reality, the inclusion of this question in your observations shows your confusion in respect of the legal framework in which free software is developed. The inclusion of the intellectual property of others in works claimed as one's own is not a practice that has been noted in the free software community; whereas, unfortunately, it has been in the area of proprietary software. As an example, the condemnation by the Commercial Court of Nanterre, France, on 27th September 2001 of Microsoft Corp. to a penalty of 3 million francs in damages and interest, for violation of intellectual property (piracy, to use the unfortunate term that your firm commonly uses in its publicity). You go on to say that: "The bill uses the concept of open source software incorrectly, since it does not necessarily imply that the software is free or of zero cost, and so arrives at mistaken conclusions regarding State savings, with no cost-benefit analysis to validate its position." This observation is wrong; in principle, freedom and lack of cost are orthogonal concepts: there is software which is proprietary and charged for (for example, MS Office), software which is proprietary and free of charge (MS Internet Explorer), software which is free and charged for (Red Hat, SuSE etc GNU/Linux distributions), software which is free and not charged for (Apache, Open Office, Mozilla), and even software which can be licensed in a range of combinations (MySQL). Certainly free software is not necessarily free of charge. And the text of the bill does not state that it has to be so, as you will have noted after reading it. The definitions included in the Bill state clearly *what* should be considered free software, at no point referring to freedom from charges. Although the possibility of savings in payments for proprietary software licenses are mentioned, the foundations of the bill clearly refer to the fundamental guarantees to be preserved and to the stimulus to local technological development. Given that a democratic State must support these principles, it has no other choice than to use software with publicly available source code, and to exchange information only in standard formats. If the State does not use software with these characteristics, it will be weakening basic republican principles. Luckily, free software also implies lower total costs; however, even given the hypothesis (easily disproved) that it was more expensive than proprietary software, the simple existence of an effective free software tool for a particular IT function would oblige the State to use it; not by command of this Bill, but because of the basic principles we enumerated at the start, and which arise from the very essence of the lawful democratic State. You continue: "6. It is wrong to think that Open Source Software is free of charge. Research by the Gartner Group (an important investigator of the technological market recognized at world level) has shown that the cost of purchase of software (operating system and applications) is only 8% of the total cost which firms and institutions take on for a rational and truly beneficial use of the technology. The other 92% consists of: installation costs, enabling, support, maintenance, administration, and down-time." This argument repeats that already given in paragraph 5 and partly contradicts paragraph 3. For the sake of brevity we refer to the comments on those paragraphs. However, allow me to point out that your conclusion is logically false: even if according to Gartner Group the cost of software is on average only 8% of the total cost of use, this does not in any way deny the existence of software which is free of charge, that is, with a licensing cost of zero. In addition, in this paragraph you correctly point out that the service components and losses due to down-time make up the largest part of the total cost of software use, which, as you will note, contradicts your statement regarding the small value of services suggested in paragraph 3. Now the use of free software contributes significantly to reduce the remaining life-cycle costs. This reduction in the costs of installation, support etc. can be noted in several areas: in the first place, the competitive service model of free software, support and maintenance for which can be freely contracted out to a range of suppliers competing on the grounds of quality and low cost. This is true for installation, enabling, and support, and in large part for maintenance. In the second place, due to the reproductive characteristics of the model, maintenance carried out for an application is easily replicable, without incurring large costs (that is, without paying more than once for the same thing) since modifications, if one wishes, can be incorporated in the common fund of knowledge. Thirdly, the huge costs caused by non-functioning software ("blue screens of death", malicious code such as virus, worms, and trojans, exceptions, general protection faults and other well-known problems) are reduced considerably by using more stable software; and it is well known that one of the most notable virtues of free software is its stability. You further state that: "7. One of the arguments behind the bill is the supposed freedom from costs of open-source software, compared with the costs of commercial software, without taking into account the fact that there exist types of volume licensing which can be highly advantageous for the State, as has happened in other countries." I have already pointed out that what is in question is not the cost of the software but the principles of freedom of information, accessibility, and security. These arguments have been covered extensively in the preceding paragraphs to which I would refer you. On the other hand, there certainly exist types of volume licensing (although unfortunately proprietary software does not satisfy the basic principles). But as you correctly pointed out in the immediately preceding paragraph of your letter, they only manage to reduce the impact of a component which makes up no more than 8% of the total. You continue: "8. In addition, the alternative adopted by the bill (I) is clearly more expensive, due to the high costs of software migration, and (II) puts at risk compatibility and interoperability of the IT platforms within the State, and between the State and the private sector, given the hundreds of versions of open source software on the market." Let us analyze your statement in two parts. Your first argument, that migration implies high costs, is in reality an argument in favor of the Bill. Because the more time goes by, the more difficult migration to another technology will become; and at the same time, the security risks associated with proprietary software will continue to increase. In this way, the use of proprietary systems and formats will make the State ever more dependent on specific suppliers. Once a policy of using free software has been established (which certainly, does imply some cost) then on the contrary migration from one system to another becomes very simple, since all data is stored in open formats. On the other hand, migration to an open software context implies no more costs than migration between two different proprietary software contexts, which invalidates your argument completely. The second argument refers to "problems in interoperability of the IT platforms within the State, and between the State and the private sector" This statement implies a certain lack of knowledge of the way in which free software is built, which does not maximize the dependence of the user on a particular platform, as normally happens in the realm of proprietary software. Even when there are multiple free software distributions, and numerous programs which can be used for the same function, interoperability is guaranteed as much by the use of standard formats, as required by the bill, as by the possibility of creating interoperable software given the availability of the source code. You then say that: "9. The majority of open source code does not offer adequate levels of service nor the guarantee from recognized manufacturers of high productivity on the part of the users, which has led various public organizations to retract their decision to go with an open source software solution and to use commercial software in its place." This observation is without foundation. In respect of the guarantee, your argument was rebutted in the response to paragraph 4. In respect of support services, it is possible to use free software without them (just as also happens with proprietary software), but anyone who does need them can obtain support separately, whether from local firms or from international corporations, again just as in the case of proprietary software. On the other hand, it would contribute greatly to our analysis if you could inform us about free software projects *established* in public bodies which have already been abandoned in favor of proprietary software. We know of a good number of cases where the opposite has taken place, but not know of any where what you describe has taken place. You continue by observing that: "10. The bill discourages the creativity of the Peruvian software industry, which invoices 40 million US$/year, exports 4 million US$ (10th in ranking among non-traditional exports, more than handicrafts) and is a source of highly qualified employment. With a law that encourages the use of open source, software programmers lose their intellectual property rights and their main source of payment." It is clear enough that nobody is forced to commercialize their code as free software. The only thing to take into account is that if it is not free software, it cannot be sold to the public sector. This is not in any case the main market for the national software industry. We covered some questions referring to the influence of the Bill on the generation of employment which would be both highly technically qualified and in better conditions for competition above, so it seems unnecessary to insist on this point. What follows in your statement is incorrect. On the one hand, no author of free software loses his intellectual property rights, unless he expressly wishes to place his work in the public domain. The free software movement has always been very respectful of intellectual property, and has generated widespread public recognition of its authors. Names like those of Richard Stallman, Linus Torvalds, Guido van Rossum, Larry Wall, Miguel de Icaza, Andrew Tridgell, Theo de Raadt, Andrea Arcangeli, Bruce Perens, Darren Reed, Alan Cox, Eric Raymond, and many others, are recognized world-wide for their contributions to the development of software that is used today by millions of people throughout the world. On the other hand, to say that the rewards for authors rights make up the main source of payment of Peruvian programmers is in any case a guess, in particular since there is no proof to this effect, nor a demonstration of how the use of free software by the State would influence these payments. You go on to say that: "11. Open source software, since it can be distributed without charge, does not allow the generation of income for its developers through exports. In this way, the multiplier effect of the sale of software to other countries is weakened, and so in turn is the growth of the industry, while Government rules ought on the contrary to stimulate local industry." This statement shows once again complete ignorance of the mechanisms of and market for free software. It tries to claim that the market of sale of non- exclusive rights for use (sale of licenses) is the only possible one for the software industry, when you yourself pointed out several paragraphs above that it is not even the most important one. The incentives that the bill offers for the growth of a supply of better qualified professionals, together with the increase in experience that working on a large scale with free software within the State will bring for Peruvian technicians, will place them in a highly competitive position to offer their services abroad. You then state that: "12. In the Forum, the use of open source software in education was discussed, without mentioning the complete collapse of this initiative in a country like Mexico, where precisely the State employees who founded the project now state that open source software did not make it possible to offer a learning experience to pupils in the schools, did not take into account the capability at a national level to give adequate support to the platform, and that the software did not and does not allow for the levels of platform integration that now exist in schools." In fact Mexico has gone into reverse with the Red Escolar (Schools Network) project. This is due precisely to the fact that the driving forces behind the Mexican project used license costs as their main argument, instead of the other reasons specified in our project, which are far more essential. Because of this conceptual mistake, and as a result of the lack of effective support from the SEP (Secretary of State for Public Education), the assumption was made that to implant free software in schools it would be enough to drop their software budget and send them a CD ROM with Gnu/Linux instead. Of course this failed, and it couldn't have been otherwise, just as school laboratories fail when they use proprietary software and have no budget for implementation and maintenance. That's exactly why our bill is not limited to making the use of free software mandatory, but recognizes the need to create a viable migration plan, in which the State undertakes the technical transition in an orderly way in order to then enjoy the advantages of free software. You end with a rhetorical question: "13. If open source software satisfies all the requirements of State bodies, why do you need a law to adopt it? Shouldn't it be the market which decides freely which products give most benefits or value?" We agree that in the private sector of the economy, it must be the market that decides which products to use, and no state interference is permissible there. However, in the case of the public sector, the reasoning is not the same: as we have already established, the state archives, handles, and transmits information which does not belong to it, but which is entrusted to it by citizens, who have no alternative under the rule of law. As a counterpart to this legal requirement, the State must take extreme measures to safeguard the integrity, confidentiality, and accessibility of this information. The use of proprietary software raises serious doubts as to whether these requirements can be fulfilled, lacks conclusive evidence in this respect, and so is not suitable for use in the public sector. The need for a law is based, firstly, on the realization of the fundamental principles listed above in the specific area of software; secondly, on the fact that the State is not an ideal homogeneous entity, but made up of multiple bodies with varying degrees of autonomy in decision making. Given that it is inappropriate to use proprietary software, the fact of establishing these rules in law will prevent the personal discretion of any state employee from putting at risk the information which belongs to citizens. And above all, because it constitutes an up-to-date reaffirmation in relation to the means of management and communication of information used today, it is based on the republican principle of openness to the public. In conformance with this universally accepted principle, the citizen has the right to know all information held by the State and not covered by well- founded declarations of secrecy based on law. Now, software deals with information and is itself information. Information in a special form, capable of being interpreted by a machine in order to execute actions, but crucial information all the same because the citizen has a legitimate right to know, for example, how his vote is computed or his taxes calculated. And for that he must have free access to the source code and be able to prove to his satisfaction the programs used for electoral computations or calculation of his taxes. I wish you the greatest respect, and would like to repeat that my office will always be open for you to expound your point of view to whatever level of detail you consider suitable. Cordially,

    Matthew Garrett: Unicode 6.0

    As Roozbeh noted, Unicode 6.0 came out yesterday. Somewhat fittingly (given it having been National Coming Out Day), it adds
    U+1F46C TWO MEN HOLDING HANDS and
    U+1F46D TWO WOMEN HOLDING HANDS

    Unfortunately most people will probably be looking at small boxes with numbers in there for a while yet, which is probably a wonderful metaphor but I'm not quite sure for what.

    I love Unicode. I love that it lets me produce correct typography without having to resort to . I love that it allows for hilarity like Zalgo and years of entertainment in searching for the limits of the LCA conference badge rendering. I'm thrilled that a poorly managed introduction of IDNs let me get away with things like www. .net, and that nobody's got around to taking it away from me yet. And U+1F64C PERSON RAISING BOTH HANDS IN CELEBRATION is going to be a core part of my IRC character set the moment I get a compose map that includes compose+\+o+/. But I also love little things like having the typographical freedom to express whatever kind of relationship I choose to.

    Well, providing that it's between two adults. Maybe 6.1 should add combining variants?

    Uwe Hermann: Using the HP Pavilion dv7-3127eg laptop with Debian GNU/Linux

    HP Pavilion dv7-3127eg Yep, so I bought a new laptop recently, my IBM/Lenovo Thinkpad T40p was slowly getting really unbearably sloooow (Celeron 1.5 GHz, 2 GB RAM max). After comparing some models I set out to buy a certain laptop in a local store, which they didn't have in stock, so I spontaneously got another model, the HP Pavilion dv7-3127eg (HP product number VY554EA). Why this one? Well, the killer feature for me was that it has two SATA disks, hence allows me to run a RAID-1 in my laptop. This allows me to sleep better at night, knowing that the next dying disk will not necessarily lead to data loss (yes, I do still perform regular backups, of course). Other pros: Much faster than the old notebook, this one is an AMD Turion II Dual-Core Mobile M520 at 2.3 GHz per core, it has 4 GB RAM (8 GB max), and uses an AMD RS780 / SB700 chipset which is supported by the Free-Software / Open-Source BIOS / firmware project coreboot, so this might make the laptop a good coreboot-target on the long run. I'll probably start working on that when I'm willing to open / dissect it or when the warranty expires, whichever happens first. Anyway, I set up a page at randomprojects.org which contains lots more details about using Linux on this laptop:
    http://randomprojects.org/wiki/HP_Pavilion_dv7-3127eg
    Most of the hardware is supported out of the box, though I haven't yet tested everything. There may be issues with suspend-to-disk / suspend-to-RAM, sometimes it seems to hang (may be just a simple config change is needed in /etc/hibernate/disk.cfg). Cons: Pretty big and heavy (but that's OK, I use it mostly as "semi-mobile desktop replacement"), glossy screen, loud fans (probably due to the two disks). For reference, here's an lspci of the box:

    Alastair McKinstry: EGU 2010 - Monday

    I'm at the European Geosciences Union (EGU) General Assembly, 2010, the biggest gethering of European geoscientists, in Vienna, May 2-7. This is my first time here and its huge: over 9000 participants. Merely finding the talks and posters is a challenge (they supply a USB stick with the abstracts and agendas as they can't print them all! The first day I spent mostly at the exoplanet stream (and putting up my own poster). Some neat stuff on show: summaries by Borucki on Keplers findings (on the Hot Jupiters they found :" these things glow like a blast furnace; forget life"). He points out that when they look for Earth sized planets, radial velocity confirmation would take 1000s of hours on 10M telescopes - so it won't happen. hmm. Steve Unwin on SIM: neat astrometric mission for planet hunting and galaxy measurement. A targeted mission list, unlike the Gaia survey; to fly in 2016 if the Decadal survey says yes. 20% of time available under the general observer program, so get proposals ready ? Nestest poster idea: Anomalous night-time temps on Mars, Gonzales et al.. Finding hot spots on Arsia Mons, a volcano. Explained by air rising from 100km long lava tubes. We've seen pit entrances to caves on Mars with HiRISE, etc. here they model heat output from a pit entrace/exit and imply 100km caves. Oh to go exploring... Tinetti points out that we lack proper spectra, both experimental and theoretical, for high temperature and pressure gases such as methane, etc. Hmm, I know a group in Galway that might be able to help ... Helmut Lammer raised an interesting point at the poster session, that many groups ignore the stellar wind when looking at H2 atmospheres around exoplanets. Theis grossly inflates the apparent H2 atmosphere. Without taking this into acount it would be easy to mistake H2 detections with a Neptune-like atmosphere. He points to a 1.7M UV telescope that the Russians are planning to launch that would help do UV measurements when Hubble is gone. Lena Noack gave a talk on convection in tidally-locked planets (with related poster Low-lid formation on Super-Earths and implications for the habitability of Super-Earths and Sub-Earths). They argue that no covection can be expected in the mantle, and hence no geodynamo or magnetosphere. This could be a problem for holding an atmosphere. Time to check for planetary magnetic fields.

    Alastair McKinstry: EGU 2010 - Monday

    I'm at the European Geosciences Union (EGU) General Assembly, 2010, the biggest gethering of European geoscientists, in Vienna, May 2-7. This is my first time here and its huge: over 9000 participants. Merely finding the talks and posters is a challenge (they supply a USB stick with the abstracts and agendas as they can't print them all! The first day I spent mostly at the exoplanet stream (and putting up my own poster). Some neat stuff on show: summaries by Borucki on Keplers findings (on the Hot Jupiters they found :" these things glow like a blast furnace; forget life"). He points out that when they look for Earth sized planets, radial velocity confirmation would take 1000s of hours on 10M telescopes - so it won't happen. hmm. Steve Unwin on SIM: neat astrometric mission for planet hunting and galaxy measurement. A targeted mission list, unlike the Gaia survey; to fly in 2016 if the Decadal survey says yes. 20% of time available under the general observer program, so get proposals ready ? Nestest poster idea: Anomalous night-time temps on Mars, Gonzales et al.. Finding hot spots on Arsia Mons, a volcano. Explained by air rising from 100km long lava tubes. We've seen pit entrances to caves on Mars with HiRISE, etc. here they model heat output from a pit entrace/exit and imply 100km caves. Oh to go exploring... Tinetti points out that we lack proper spectra, both experimental and theoretical, for high temperature and pressure gases such as methane, etc. Hmm, I know a group in Galway that might be able to help ... Helmut Lammer raised an interesting point at the poster session, that many groups ignore the stellar wind when looking at H2 atmospheres around exoplanets. Theis grossly inflates the apparent H2 atmosphere. Without taking this into acount it would be easy to mistake H2 detections with a Neptune-like atmosphere. He points to a 1.7M UV telescope that the Russians are planning to launch that would help do UV measurements when Hubble is gone.

    Gunnar Wolf: Authoral rights in the editorial world seminar

    I must confess I don't remember who I got this invitation from. Anyway, if you are in the right geographic area, you might be interested. I will try to participate: This is a year-long seminar that will be held the second Thursday every month at Fonoteca Nacional (a place I have wanted to visit for a long time!), in Barrio de Santa Catarina, Coyoac n. Among the organizers they have Creative Commons Mexico. Free entrance (but limited space - so they ask interested people to confirm their presence by mail to bvallarta@conaculta.gob.mx). [update] I went with Pooka to the first session. We arrived almost 1hr late (due to me mistaking the schedule :-/ ) but it was interesting. Of course, quite biased towards the Google viewpoints, but interesting. We got the program for the next sessions So, mostly for myself to keep handy, here it goes:

    Aigars Mahinovs: New hardware planning

    My primary workstation is a 3 and a half year old Dell XPS M1710 laptop and it is getting old the 320 Gb hard drive is getting small and slow, the 3 Gb or RAM (expanded from 2 Gb) look too small and screen is turning brown in one corner. Also dead or dying: keyboard (after cat+coffee incident), built-in speakers, battery, power adapter (twice replaced), DVD writer (rads but does not write any more) and fans (one replaced, one getting louder by the week). Also the video card is a bit slow for nowadays needs. So I set aside some money and started considering the options. In short, I could get another laptop OR get a regular computer for the same price but with twice the power. After considering all the laptop options up to 1000LVL, I decided to get a regular computer and if/when I ll need to travel I ll either take one of the old laptops with me or get a new netbook. Now comes the fun part choosing the components! So far my choices are as follows: And that is it a great setup that will last me a few years for around 700 LVL and it will have more partial upgradability than my laptop that I paid twice as much 3 years ago. Any tips? Did I miss anything? Is it likely that anything in the above list will cause me any trouble in latest Ubuntu/Debian installations? Update: got all of the above, except 500 Gb HDD of the same kind (faster, cooler, but higher price per Gb) and no Blueray (no drive in LV at the moment and did not want to wait a few weeks). The results are good, but I wish I would have gone with a 5 LVL more expensive video card that has a quieter cooler. Now I am buying a separate video card cooler for around 20 LVL that will be both more efficient and much quieter than the stock cooler I have Zalman VF1000 is the model. Has not arrived yet. P.S. It looks like updating a post in WP, automatically bumps it back into the Planet feed. Sorry :(

    Gunnar Wolf: Lovin' it in Afghanistan

    Lovin' it in Afghanistan
    A couple of weeks ago, I was invited to travel to Colombia, where I delivered a talk at III Encuentro Internacional de Seguridad Inform tica in the city of Manizales (photos available, of course. I travelled with Colombia's nacional airline, Avianca. On completely unrelated news, today I entered Avianca's website to check my miles. To my biggest amusement Turns out I am now a resident of Bamiyan, Afghanistan! (I swear I didn't select that) Seems they do beard-based georeferentiation?
    NP: Hey, mister Taliban, tally me bananas
    daylight come and me wanna go home!

    Christian Perrier: Glasses

    I'm now wearing glasses. Reaching birthdays between 45 and 50 gives one nice gift: presbytia. In a few months, my arms were getting longer and longer while I was reading, to the extent that it became difficult to read, and even hack on the laptop during evenings. As a consequence, I won a visit to an ophtalmologist and then got a prescription for glasses. Luckily for me, my wife (and my son, indeed) works for the Essilor International company, world leader of corrective glasses, and particularly makers of the quite famous "Varilux" progressive glasses. So, I could get their top product, Varilux Physio glasses with Cryzal Forte anti-reflection treatments. Getting used to these nice pieces of glass technology is quite tricky but the result is...amazing, even for my far vision (which I thought was perfect until now). So, expect some pics soon...or, alternatively just come at Debconf9...:-)

    Gunnar Wolf: Some prefer marathoning... I prefer going to my old workplace

    I was invited to talk about Free Software at yesterday's FLISOL. Yesterday? Aren't FLISOLs organized on Saturday? Well, not this one, for various reasons which I won't quote here. And no, I am not a supporter of the installfests idea, but I went gladly to talk about what is Free Software all about - The philosophy behind Free Software. Besides, the talk was at FES Iztacala, where I worked for four happy years, 1999-2003. I have not been often to Iztacala since 2003 (probably I have visited only three or four times), partly because of the distance (~25Km from home in a straight line, but the city's Northern part is quite poorly communicated). The last time I was there, last October, I went by bike, just to test my endurance and... because I could. Yesterday, I also did, not to be outdone by my fellow Debianers Christian and Dirk. Think they are so cool because they can run for 43Km? Well, I had my 55Km yesterday, and I was not even in a competition! (yes, yes, running and biking is not the same. So sue me. I just didn't want to stand still and let them walk away with all of the fun!) I took slightly different routes (my route to get there on Nokia Sportstracker and OpenStreetMap trace, my route back on Nokia Sportstracker and OpenStreetMap trace), crossing diagonally Azcapotzalco, a region of the city (delegaci n) I hardly know... The Sourthern of it seems like a continuation of Tacuba to the North, small and not-very-well-communicated prior villages engulfed by our hungry, huge city. The Northern half is a mostly industrial area, with very sparse population, lots of trucks, and streets that are not in the best shape. You can end up feeling lonely in those regions, and I am glad not to have crossed back by night. And the trip back was interesting as well... Mexico City is home to many more bikers you would expect given its size, and it is very common to find other people doing nice long stretches. In this case, I started cycling quite close to another guy in a white bike more or less when I got to Calzada Camarones. Possibly we had passed each other over and over until after Tlatelolco, arriving to Guerrero, where I approached him at a stoplight:
    Hi! Where to?
    Near Vocacional 7, Iztapalapa!
    Nice! I'm just going to Copilco Every now and then we crossed each other... Turns out he does this ~30Km commute daily between Iztapalapa and Azcapotzalco. Quite admirable, to be honest. I also crossed my road with Sergio Mendoza, fellow Debianer (and co-administrator of our Mexican mirror) around Centro M dico (about 7Km north from my destination), whom I had only seen before around the University. Nice surprise. And yes, getting to know the city by bike is the best way to go! Back to the conference... my first thought when I was invited was to present Qu es el Software Libre?, a talk I have given over and over since... 2002 (although, yes, with updates). I must say it's one of the best structured talks I have prepared and has almost always been very successful - But give the same talk based on the same script over and over (AFAICT, around 20 times), and you will be fed up with it. And yes, yesterday I didn't take my laptop along, and didn't put my presentation on a USB stick - I took a pen and some paper, and during the presentation prior to mine, wrote some points to go over. And yes, it was a refreshing change. The talk was as successful as expected, and it's much more refreshing to talk about the same topics bot on a different way, and without being constrained to a predefined script. I know that organizing formally your ideas makes sure you don't miss out important points and that the audience is sometimes encouraged to pay attention by having some bullet points to look at - But on the other hand, it is much easier to follow your audience's interest if you are not bound by the script. And the few times I've spoken that way, it has felt refreshing and nice.
