The many definitions of a open standard
+
2010-12-27 14:45
-

Personvernet et under kontinuerlig og kraftig angrep. Her er noen -stemmer i debatten.

+

One of the reasons I like the Digistan definition of +"Free and +Open Standard" is that this is a new term, and thus the meaning of +the term has been decided by Digistan. The term "Open Standard" has +become so misunderstood that it is no longer useful very when talking +about standards. One end up discussing which definition is the best +one and with such frame the only one gaining are the proponents of +de-facto standards and proprietary solutions.

+ +

But to give us an idea about the diversity of definitions of open +standards, here are a few that I know about. This list is not +complete, but can be a starting point for those that want to do a +complete survey. More definitions are available on the +wikipedia +page.

+ +

First off is my favourite, the definition from the European +Interoperability Framework version 1.0. Really sad to notice that BSA +and others has succeeded in getting it removed from version 2.0 of the +framework by stacking the committee drafting the new version with +their own people. Anyway, the definition is still available and it +include the key properties needed to make sure everyone can use a +specification on equal terms.

-

+ + + +

It is said that one of the nice things about standards is that +there are so many of them. As you can see, the same holds true for +open standard definitions. Most of the definitions have a lot in +common, and it is not really controversial what properties a open +standard should have, but the diversity of definitions have made it +possible for those that want to avoid a level marked field and real +competition to downplay the significance of open standards. I hope we +can turn this tide by focusing on the advantages of Free and Open +Standards.

First version of a Perl library to control the Spykee robot

Is Ogg Theora a free and open standard?
+
2010-12-25 20:25
-

This summer I got the chance to buy cheap Spykee robots, and since -then I have worked on getting Linux software in place to control them. -The firmware for the robot is available from the producer, and using -that source it was trivial to figure out the protocol specification. -I've started on a perl library to control it, and made some demo -programs using this perl library to allow one to control the -robots.

- -

The library is quite functional already, and capable of controlling -the driving, fetching video, uploading MP3s and play them. There are -a few less important features too.

- -

Since a few weeks ago, I ran out of time to spend on this project, -but I never got around to releasing the current source. I decided -today that it was time to do something about it, and uploaded the -source to my Debian package store at people.skolelinux.org.

- -

Because it was simpler for me, I made a Debian package and -published the source and deb. If you got a spykee robot, grab the -source or binary package:

- -

- -

If you are interested in helping out with developing this library, -please let me know.

+

The +Digistan definition of a free and open standard reads like this:

+ +
+ +

The Digital Standards Organization defines free and open standard +as follows:

+ +
    + +
  1. A free and open standard is immune to vendor capture at all stages +in its life-cycle. Immunity from vendor capture makes it possible to +freely use, improve upon, trust, and extend a standard over time.
  2. + +
  3. The standard is adopted and will be maintained by a not-for-profit +organisation, and its ongoing development occurs on the basis of an +open decision-making procedure available to all interested +parties.
  4. + +
  5. The standard has been published and the standard specification +document is available freely. It must be permissible to all to copy, +distribute, and use it freely.
  6. + +
  7. The patents possibly present on (parts of) the standard are made +irrevocably available on a royalty-free basis.
  8. + +
  9. There are no constraints on the re-use of the standard.
  10. + +
+ +

The economic outcome of a free and open standard, which can be +measured, is that it enables perfect competition between suppliers of +products based on the standard.

+
+ +

For a while now I have tried to figure out of Ogg Theora is a free +and open standard according to this definition. Here is a short +writeup of what I have been able to gather so far. I brought up the +topic on the Xiph advocacy mailing list +in +July 2009, for those that want to see some background information. +According to Ivo Emanuel Gonçalves and Monty Montgomery on that list +the Ogg Theora specification fulfils the Digistan definition.

+ +

Free from vendor capture?

+ +

As far as I can see, there is no single vendor that can control the +Ogg Theora specification. It can be argued that the +Xiph foundation is such vendor, but +given that it is a non-profit foundation with the expressed goal +making free and open protocols and standards available, it is not +obvious that this is a real risk. One issue with the Xiph +foundation is that its inner working (as in board member list, or who +control the foundation) are not easily available on the web. I've +been unable to find out who is in the foundation board, and have not +seen any accounting information documenting how money is handled nor +where is is spent in the foundation. It is thus not obvious for an +external observer who control The Xiph foundation, and for all I know +it is possible for a single vendor to take control over the +specification. But it seem unlikely.

+ +

Maintained by open not-for-profit organisation?

+ +

Assuming that the Xiph foundation is the organisation its web pages +claim it to be, this point is fulfilled. If Xiph foundation is +controlled by a single vendor, it isn't, but I have not found any +documentation indicating this.

+ +

According to +a report +prepared by Audun Vaaler og Børre Ludvigsen for the Norwegian +government, the Xiph foundation is a non-commercial organisation and +the development process is open, transparent and non-Discrimatory. +Until proven otherwise, I believe it make most sense to believe the +report is correct.

+ +

Specification freely available?

+ +

The specification for the Ogg +container format and both the +Vorbis and +Theora codeces are available on +the web. This are the terms in the Vorbis and Theora specification: + +

+ +Anyone may freely use and distribute the Ogg and [Vorbis/Theora] +specifications, whether in private, public, or corporate +capacity. However, the Xiph.Org Foundation and the Ogg project reserve +the right to set the Ogg [Vorbis/Theora] specification and certify +specification compliance. + +
+ +

The Ogg container format is specified in IETF +RFC 3533, and +this is the term:

+ +

+ +

This document and translations of it may be copied and furnished to +others, and derivative works that comment on or otherwise explain it +or assist in its implementation may be prepared, copied, published and +distributed, in whole or in part, without restriction of any kind, +provided that the above copyright notice and this paragraph are +included on all such copies and derivative works. However, this +document itself may not be modified in any way, such as by removing +the copyright notice or references to the Internet Society or other +Internet organizations, except as needed for the purpose of developing +Internet standards in which case the procedures for copyrights defined +in the Internet Standards process must be followed, or as required to +translate it into languages other than English.

+ +

The limited permissions granted above are perpetual and will not be +revoked by the Internet Society or its successors or assigns.

+
+ +

All these terms seem to allow unlimited distribution and use, an +this term seem to be fulfilled. There might be a problem with the +missing permission to distribute modified versions of the text, and +thus reuse it in other specifications. Not quite sure if that is a +requirement for the Digistan definition.

+ +

Royalty-free?

+ +

There are no known patent claims requiring royalties for the Ogg +Theora format. +MPEG-LA +and +Steve +Jobs in Apple claim to know about some patent claims (submarine +patents) against the Theora format, but no-one else seem to believe +them. Both Opera Software and the Mozilla Foundation have looked into +this and decided to implement Ogg Theora support in their browsers +without paying any royalties. For now the claims from MPEG-LA and +Steve Jobs seem more like FUD to scare people to use the H.264 codec +than any real problem with Ogg Theora. + +

No constraints on re-use?

+ +

I am not aware of any constraints on re-use.

+ +

Conclusion

+ +

3 of 5 requirements seem obviously fulfilled, and the remaining 2 +depend on the governing structure of the Xiph foundation. Given the +background report used by the Norwegian government, I believe it is +safe to assume the last two requirements are fulfilled too, but it +would be nice if the Xiph foundation web site made it easier to verify +this.

+ +

It would be nice to see other analysis of other specifications to +see if they are free and open standards.

The reply from Edgar Villanueva to Microsoft in Peru
+
2010-12-25 10:50
-

+

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,
+DR. EDGAR DAVID VILLANUEVA NUÑEZ
+Congressman of the Republic of Perú.

Frikanalen og NUUG jobber for å få TED -talks kringkastet på -Frikanalen, for å gi et mer -variert innhold på kanalen som i dag sendes på RiksTV, Lyse og -Uninett. Før innslagene kan sendes må det lages norske undertekster, -og dette her trengs det frivillige. Det er hundrevis av innslag, men -mine favoritter er -James Randi og -Michael -Specter. Hvis du har litt tid til overs, bli med på å oversette -TED-foredragene til norsk og få på plass undertekster. TED har -allerede opplegg på plass for å håndtere oversettelser og -undertekster. Registrer deg på -sidene til TED i -dag!

NUUG holder også på å få alle opptakene fra NUUG-presentasjonene -publisert -på Frikanalen. Foredrag på engelsk må også her tekstes og -oversettes. Ta kontakt med video@nuug.no hvis du vil bidra med -teksting og oversetting. Arbeidet koordineres på epostlisten og på -IRC (#nuug-video på irc.oftc.org), og en wikiside -brukes som notatblokk for arbeidet. Mest lovende verktøy for dette -ser i dag ut til å være -Universal Subtitles, som -lar en bidra med teksting via en nettleser.

Half a year ago I +wrote +a bit about OfficeShots, +a web service to allow anyone to test how ODF documents are handled by +the different programs reading and writing the ODF format.

+ +

I just had a look at the service, and it seem to be going strong. +Very interesting to see the results reported in the gallery, how +different Office implementations handle different ODF features. Sad +to see that KOffice was not doing it very well, and happy to see that +LibreOffice has been tested already (but sadly not listed as a option +for OfficeShots users yet). I am glad to see that the ODF community +got such a great test tool available.

Bilkollektivet vil ha retten til å se hvor jeg kjører...

165 norske overvåkningskamera registert så langt i OpenStreetmap.org

Jeg er med i -Bilkollektivet her i Oslo, -og har inntil i dag vært fornøyd med opplegget. I dag kom det brev -fra bilkollektivet, der de forteller om nytt webopplegg og nye -rutiner, og at de har tenkt å angripe min rett til å ferdes anonymt -som bruker av Bilkollektivet. Det gjorde meg virkelig trist å -lese.

- -

Brevet datert 2010-09-16 forteller at Bilkollektivet har tenkt å gå -over til biler med "bilcomputer" og innebygget sporings-GPS som lar -administrasjonen i bilkollektivet se hvor bilene er til en hver tid, -noe som betyr at de også kan se hvor jeg kjører når jeg bruker -Bilkollektivet. -Retten -til å ferdes anonymt er som tidligere nevnt viktig for meg, og jeg -finner det uakseptabelt å måtte godta å bli radiomerket for å kunne -bruke bil. Har ikke satt meg inn i hva som er historien for denne -endringen, så jeg vet ikke om det er godkjent av -f.eks. andelseiermøtet. Ser at -nye -bilbruksregler med følgende klausul ble vedtatt av styret -2010-08-26:

- -

Andelseier er med dette gjort kjent med at bilene er -utstyrt med sporingsutstyr, som kan benyttes av Bilkollektivet til å -spore biler som brukes utenfor gyldig reservasjon.

- -

For meg er det prinsipielt uakseptabelt av Bilkollektivet å skaffe -seg muligheten til å se hvor jeg befinner meg, og det er underordnet -når informasjonen blir brukt og hvem som får tilgang til den. Får se -om jeg har energi til å forsøke å endre planene til Bilkollektivet -eller bare ser meg om etter alternativer.

Jeg flikket litt på OpenStreetmap.org i går, og oppdaget ved en +tilfeldighet at det er en rekke noder som representerer +overvåkningskamera som ikke blir med på kartet med overvåkningskamera +i Norge som +jeg +laget for snart to år siden. Fra før tok jeg med noder merket med +man_made=surveillance, mens det er en rekke noder som kun er merket +med highway=speed_camera. Endret på koden som henter ut kameralisten +fra OSM, og vips er antall kamera økt til 165.

+ +Kartet +er fortsatt ikke komplett, så hvis du ser noen kamera som mangler, +legg inn ved å følge instruksene fra +prosjektsiden. +Hvis du vet om noen flere måter å merke overvåkningskamera i OSM, ta +kontakt slik at jeg kan få med også disse.

How to test if a laptop is working with Linux
+
2010-12-22 14:55
-

For ca. et og et halvt år siden -startet -jeg på et kart over overvåkningskamera i Norge, i regi av -personvernforeningen. Det har -blitt oppdatert regelmessing, og jeg oppdaterte det nettopp. Fra den -spede start med 22 kamera registrert er det nå registrert 54 kamera. -Det er bare en brøkdel av de kamera som finnes i Norge, men det går -sakte men sikkert i riktig retning.

- -

Informasjonen registreres fortsatt direkte inn i -OpenStreetmap, og hentes -automatisk over i -spesialkartet -når jeg kjører et script for å filtrere ut overvåkningskamera fra -OSM-dumpen for Norge.

+

The last few days I have spent at work here at the University of oslo testing if the new +batch of computers will work with Linux. Every year for the last few +years the university have organized shared bid of a few thousand +computers, and this year HP won the bid. Two different desktops and +five different laptops are on the list this year. We in the UNIX +group want to know which one of these computers work well with RHEL +and Ubuntu, the two Linux distributions we currently handle at the +university.

+ +

My test method is simple, and I share it here to get feedback and +perhaps inspire others to test hardware as well. To test, I PXE +install the OS version of choice, and log in as my normal user and run +a few applications and plug in selected pieces of hardware. When +something fail, I make a note about this in the test matrix and move +on. If I have some spare time I try to report the bug to the OS +vendor, but as I only have the machines for a short time, I rarely +have the time to do this for all the problems I find.

+ +

Anyway, to get to the point of this post. Here is the simple tests +I perform on a new model.

+ + + +

By now I suspect you are really curious what the test results are +for the HP machines I am testing. I'm not done yet, so I will report +the test results later. For now I can report that HP 8100 Elite work +fine, and hibernation fail with HP EliteBook 8440p on Ubuntu Lucid, +and audio fail on RHEL6. Ubuntu Maverik worked with 8440p. As you +can see, I have most machines left to test. One interesting +observation is that Ubuntu Lucid has almost twice the framerate than +RHEL6 with glxgears. No idea why.

Some thoughts on BitCoins
+
2010-12-11 15:10
-

Debatten rundt sporveiselskapet i Oslos (Ruter AS) ønske om -å -radiomerke med RFID alle sine kunder og -registerere -hvor hver og en av oss beveger oss pågår, og en ting som har -kommet lite frem i debatten er at det faktisk er en menneskerett å -kunne ferdes anonymt internt i ens eget land.

- -

Fant en grei kilde for dette i et -skriv -fra Datatilsynet til Samferdselsdepartementet om tema:

- -

Retten til å ferdes anonymt kan utledes av -menneskerettskonvensjonen artikkel 8 og av EUs personverndirektiv. -Her heter det at enkeltpersoners grunnleggende rettigheter og frihet -må respekteres, særlig retten til privatlivets fred. I både -personverndirektivet og i den norske personopplysningsloven er -selvråderetten til hver enkelt et av grunnprinsippene, hovedsaklig -uttrykt ved at en må gi et frivillig, informert og uttrykkelig -samtykke til behandling av personopplysninger.

- -

For meg er det viktig at jeg kan ferdes anonymt, og det er litt av -bakgrunnen til at jeg handler med kontanter, ikke har mobiltelefon og -forventer å kunne reise med bil og kollektivtrafikk uten at det blir -registrert hvor jeg har vært. Ruter angriper min rett til å ferdes -uten radiopeiler med sin innføring av RFID-kort, og dokumenterer sitt -ønske om å registrere hvor kundene befant seg ved å ønske å gebyrlegge -oss som ikke registrerer oss hver gang vi beveger oss med -kollektivtrafikken i Oslo. Jeg synes det er hårreisende.

+

As I continue to explore +BitCoin, I've starting to wonder +what properties the system have, and how it will be affected by laws +and regulations here in Norway. Here are some random notes.

+ +

One interesting thing to note is that since the transactions are +verified using a peer to peer network, all details about a transaction +is known to everyone. This means that if a BitCoin address has been +published like I did with mine in my initial post about BitCoin, it is +possible for everyone to see how many BitCoins have been transfered to +that address. There is even a web service to look at the details for +all transactions. There I can see that my address +15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b +have received 16.06 Bitcoin, the +1LfdGnGuWkpSJgbQySxxCWhv8MHqvwst3 +address of Simon Phipps have received 181.97 BitCoin and the address +1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt +of EFF have received 2447.38 BitCoins so far. Thank you to each and +every one of you that donated bitcoins to support my activity. The +fact that anyone can see how much money was transfered to a given +address make it more obvious why the BitCoin community recommend to +generate and hand out a new address for each transaction. I'm told +there is no way to track which addresses belong to a given person or +organisation without the person or organisation revealing it +themselves, as Simon, EFF and I have done.

+ +

In Norway, and in most other countries, there are laws and +regulations limiting how much money one can transfer across the border +without declaring it. There are money laundering, tax and accounting +laws and regulations I would expect to apply to the use of BitCoin. +If the Skolelinux foundation +(SLX +Debian Labs) were to accept donations in BitCoin in addition to +normal bank transfers like EFF is doing, how should this be accounted? +Given that it is impossible to know if money can across the border or +not, should everything or nothing be declared? What exchange rate +should be used when calculating taxes? Would receivers have to pay +income tax if the foundation were to pay Skolelinux contributors in +BitCoin? I have no idea, but it would be interesting to know.

+ +

For a currency to be useful and successful, it must be trusted and +accepted by a lot of users. It must be possible to get easy access to +the currency (as a wage or using currency exchanges), and it must be +easy to spend it. At the moment BitCoin seem fairly easy to get +access to, but there are very few places to spend it. I am not really +a regular user of any of the vendor types currently accepting BitCoin, +so I wonder when my kind of shop would start accepting BitCoins. I +would like to buy electronics, travels and subway tickets, not herbs +and books. :) The currency is young, and this will improve over time +if it become popular, but I suspect regular banks will start to lobby +to get BitCoin declared illegal if it become popular. I'm sure they +will claim it is helping fund terrorism and money laundering (which +probably would be true, as is any currency in existence), but I +believe the problems should be solved elsewhere and not by blaming +currencies.

+ +

The process of creating new BitCoins is called mining, and it is +CPU intensive process that depend on a bit of luck as well (as one is +competing against all the other miners currently spending CPU cycles +to see which one get the next lump of cash). The "winner" get 50 +BitCoin when this happen. Yesterday I came across the obvious way to +join forces to increase ones changes of getting at least some coins, +by coordinating the work on mining BitCoins across several machines +and people, and sharing the result if one is lucky and get the 50 +BitCoins. Check out +BitCoin Pool +if this sounds interesting. I have not had time to try to set up a +machine to participate there yet, but have seen that running on ones +own for a few days have not yield any BitCoins througth mining +yet.

+ +

Update 2010-12-15: Found an interesting +criticism of bitcoin. Not quite sure how valid it is, but thought +it was interesting to read. The arguments presented seem to be +equally valid for gold, which was used as a currency for many years.

A few days ago I had the mixed pleasure of bying a new digital -camera, a Canon IXUS 130. It was instructive and very disturbing to -be able to verify that also this camera producer have the nerve to -specify how I can or can not use the videos produced with the camera. -Even thought I was aware of the issue, the options with new cameras -are limited and I ended up bying the camera anyway. What is the -problem, you might ask? It is software patents, MPEG-4, H.264 and the -MPEG-LA that is the problem, and our right to record our experiences -without asking for permissions that is at risk. - -

On page 27 of the Danish instruction manual, this section is -written:

- -
-

This product is licensed under AT&T patents for the MPEG-4 standard -and may be used for encoding MPEG-4 compliant video and/or decoding -MPEG-4 compliant video that was encoded only (1) for a personal and -non-commercial purpose or (2) by a video provider licensed under the -AT&T patents to provide MPEG-4 compliant video.

- -

No license is granted or implied for any other use for MPEG-4 -standard.

-
- -

In short, the camera producer have chosen to use technology -(MPEG-4/H.264) that is only provided if I used it for personal and -non-commercial purposes, or ask for permission from the organisations -holding the knowledge monopoly (patent) for technology used.

- -

This issue has been brewing for a while, and I recommend you to -read -"Why -Our Civilization's Video Art and Culture is Threatened by the -MPEG-LA" by Eugenia Loli-Queru and -"H.264 Is Not -The Sort Of Free That Matters" by Simon Phipps to learn more about -the issue. The solution is to support the -free and -open standards for video, like Ogg -Theora, and avoid MPEG-4 and H.264 if you can.

Via en +blogpost fra Simon Phipps i går, fant jeg en referanse til +en +artikkel i Washington Times som igjen refererer til en artikkel i +det fagfellevurderte tidsskriftet Journal of Transportation Security +med tittelen +"An +evaluation of airport x-ray backscatter units based on image +characteristics" som enkelt konstaterer at +pornoscannerne +som kler av reisende på flyplasser ikke er i stand til å avsløre det +produsenten og amerikanske myndigheter sier de skal avsløre. Kort +sagt, de bedrer ikke sikkerheten. Reisende må altså la ansatte på +flyplasser se dem +nakne eller la seg beføle i skrittet uten grunn. Jeg vil +fortsette å nekte å bruke disse pornoskannerne, unngå flyplasser der +de er tatt i bruk, og reise med andre transportmidler enn fly hvis jeg +kan.

Navteq bruker 3-12 måneder, OpenStreetmap.org trenger noen dager

Now accepting bitcoins - anonymous and distributed p2p crypto-money

Jeg ble riktig fascinert av -en -artikkel i Aftenposten om hvor hardt Navteq jobber for å oppdatere -kartene som brukes i navigasjons-GPSer, der det blant annet heter at -"på grunn av teknikken tar det alt fra tre til tolv måneder før -kartene er oppdatert". Når en kjenner hva slags oppdateringshastighet -som er tilgjengelig på -OpenStreetmap som -oppdateres på dugnad, blir det litt trist å se hva noe av det beste en -kan kjøpe for penger får til.

- -

Fra en endrer kartdataene i databasen til OpenStreetmap tar det -ca. 15 minutter før endringen er synlig på kartet som alle kan se på -web. Dernest overføres det daglig til en kartdump som lastes ned av -personen som lager Garmin-kart for Norge ca. en gang i uken. Med -OpenStreetmap.org og Frikart.no -kan en altså ha korreksjonene på plass i sin Garmin-GPS i løpet av en -uke. Det er også av tekniske årsaker at det tar så langt tid. -Jobbene som tegner kartene, henter ut kartdumpene og konverterer til -Garmin-format tar minutter og timer å gjennomføre, slik at de ikke -gjøres kontinuerlig men kun regelmessing.

+

With this weeks lawless +governmental +attacks on Wikileak and +free +speech, it has become obvious that PayPal, visa and mastercard can +not be trusted to handle money transactions. +A blog post from +Simon +Phipps on bitcoin reminded me about a project that a friend of +mine mentioned earlier. I decided to follow Simon's example, and get +involved with BitCoin. I got +some help from my friend to get it all running, and he even handed me +some bitcoins to get started. I even donated a few bitcoins to Simon +for helping me remember BitCoin.

+ +

So, what is bitcoins, you probably wonder? It is a digital +crypto-currency, decentralised and handled using peer-to-peer +networks. It allows anonymous transactions and prohibits central +control over the transactions, making it impossible for governments +and companies alike to block donations and other transactions. The +source is free software, and while the key dependency wxWidgets 2.9 +for the graphical user interface is missing in Debian, the command +line client builds just fine. Hopefully Jonas +will get the package into +Debian soon.

+ +

Bitcoins can be converted to other currencies, like USD and EUR. +There are companies accepting +bitcoins when selling services and goods, and there are even +currency "stock" markets where the exchange rate is decided. There +are not many users so far, but the concept seems promising. If you +want to get started and lack a friend with any bitcoins to spare, +you can even get +some for free (0.05 +bitcoin at the time of writing). Use +BitcoinWatch to keep an eye +on the current exchange rates.

+ +

As an experiment, I have decided to set up bitcoind on one of my +machines. If you want to support my activity, please send Bitcoin +donations to the address +15oWEoG9dUPovwmUL9KWAnYRtNJEkP1u1b. Thank you!

Martin Bekkelund: En stille bønn om Datalagringsdirektivet
+
2010-12-09 21:25
-

In the Debian -popularity-contest numbers, the adobe-flashplugin package the -second most popular used package that is missing in Debian. The sixth -most popular is flashplayer-mozilla. This is a clear indication that -working flash is important for Debian users. Around 10 percent of the -users submitting data to popcon.debian.org have this package -installed.

- -

In the report written by Lars Risan in August 2008 -(«Skolelinux -i bruk – Rapport for Hurum kommune, Universitetet i Agder og -stiftelsen SLX Debian Labs»), one of the most important problems -schools experienced with Debian -Edu/Skolelinux was the lack of working Flash. A lot of educational -web sites require Flash to work, and lacking working Flash support in -the web browser and the problems with installing it was perceived as a -good reason to stay with Windows.

- -

I once saw a funny and sad comment in a web forum, where Linux was -said to be the retarded cousin that did not really understand -everything you told him but could work fairly well. This was a -comment regarding the problems Linux have with proprietary formats and -non-standard web pages, and is sad because it exposes a fairly common -understanding of whose fault it is if web pages that only work in for -example Internet Explorer 6 fail to work on Firefox, and funny because -it explain very well how annoying it is for users when Linux -distributions do not work with the documents they receive or the web -pages they want to visit.

- -

This is part of the reason why I believe it is important for Debian -and Debian Edu to have a well working Flash implementation in the -distribution, to get at least popular sites as Youtube and Google -Video to working out of the box. For Squeeze, Debian have the chance -to include the latest version of Gnash that will make this happen, as -the new release 0.8.8 was published a few weeks ago and is resting in -unstable. The new version work with more sites that version 0.8.7. -The Gnash maintainers have asked for a freeze exception, but the -release team have not had time to reply to it yet. I hope they agree -with me that Flash is important for the Debian desktop users, and thus -accept the new package into Squeeze.

+

Martin Bekkelund ved +friprog-senteret har skrevet +følgende +korte +oppsummering rundt datalagringsdirektivet, som jeg videreformidler +her.

+ +

Det pågår i disse dager en intens diskusjon om +innføring av Datalagringsdirektivet (DLD) i norsk rett. Kanskje +har du gjort deg opp en mening, kanskje er du usikker. I begge +tilfeller ber jeg deg lese videre.

+ +

Samtlige fagmiljøer, både i Norge og EU, har konkludert med at +DLD ikke bør +innføres på nåværende tidspunkt. Den tekniske kvaliteten på direktivet +er dårlig, det griper uforholdsmessig inn i personvernet, det har +store mangler og viktige spørsmål som hvem som skal ha tilgang og +hvordan data skal lagres er fortsatt uavklart.

+ + + +

Jeg liker å tro at jeg er en hyggelig fyr. Jeg har et rent +rulleblad, og med unntak av to fartsbøter har jeg aldri vært en byrde +for samfunnet. Det akter jeg å fortsette med. Det er mange som meg, +lovlydige, pliktoppfyllende borgere som aldri vil utgjøre en trussel +mot noe som helst. Vi synes derfor det er trist og sårende at all vår +atferd skal overvåkes døgnkontinuerlig.

+ +

Understøttet av faglige vurderinger kan du trygt si nei til +DLD.

+ +

Ta kontakt med meg +hvis du har spørsmål om DLD, uansett hva det måtte +gjelde.

+ +

Denne teksten er å anse som Public +Domain. Spre den videre til alle som kan ha nytte av +den!

+

+ +

Siste melding +fra Nettavisen er at regjeringen planlegger å fremme sitt forslag +til implementering av datalagringsdirektivet i morgen, i ly av +fredprisutdelingen for å få minst mulig pressedekning om saken. Vi +får snart se om det stemmer.
