I learnt yesterday that one of my favourite guitar players passed away. Huw Lloyd Langton got notorious through his work with Hawkwind, a collaboration that spanned a good number of decades. Master of spacey reverbs and long improvisations, he could create dense atmospheres but still produce songs for more straightforward listeners. I never had the opportunity to see Huw playing live, and now I'm sure I never will. Folk that worked with him paint a personality of kindness and openness, someone pleasant to do music with. Good bye Huw, you'll be missed.

Petition for a Better Ubuntu

Not much has happened since I reported on the potential incompatibilities of Ubuntu 12.10 with the European data protection legislation. At the time I got the impression Canonical was not even in tune to personal data protection and the company remained almost silent on the issue, avoiding to address it directly. I find this somewhat strange, for Mark Shuttleworth, the company
Update: The text of this petition has been kindly translated into French by Vince.

Muse brings Peak Oil to the mainstream
Muse is a modern British progressive rock band, one of an handful that has harnessed commercial success during the past decade. They rank 9th in my Last.fm top, although time wise they just nearly make it into the top 25. The band released a new LP, the sixth of their career, about 2 months ago. So far I've been too busy to lend any attention to it, although friends already referenced it as well worth listen.
Thanks to our galician friends at Véspera de Nada I found out today that this LP is actually a reflection on the energy sustainability of modern society. Here's the trailer of The 2nd Law

Alternative materials

The energy transition modern societies are undergoing today can also be (and most likely will be) a transition into a different way of using matter. A possibility that has been explorer since the 1960s is the usage of carbon fibre composites to replace metals in a variety of applications. Strong and light, they have been promising a new Industrial Revolution for a long time. But while carbon fibres dispense much of the energy consumption of mining and refining processes, they still require relevant amounts of energy in its fabrication process; barring relevant innovation on this aspect, carbon fibre won't become an everyday material.
It so happens that Nature itself fabricates materials not that different from carbon fibre reinforced polymers. Trees produce their own polymers, cellulose and lignen, that are bound together into a material that has great resistance to compression and tension: wood.

Legal questions on the Ubuntu Shopping Lens
Several developments have followed the announcement of the default inclusion of the Shopping Lens feature in Ubuntu 12.10. What seemed at first a surreptitious inclusion of adware in Ubuntu turned into a full blown row when Mark Shutleworth, founder of Canonical, the company that coordinates the Ubuntu development, lit afire the blogosphere claiming that the company had administrative access to every computer running Ubuntu. From there we got to know that even the users that could benefit from the feature are not happy, since the results can not be filtered or customised. A further consequence of this is the possibility of adult oriented products showing up in the results, which puts at risk Ubuntu's usage by children and in professional environments. Answering to all the backlash, Canonical has decided to include settings that allow the user to switch off the Shopping Lens, but it will still be switched on by default.
Actually, this may be just the tip of the iceberg. The inclusion of this commercial oriented feature, more over by default, has the potential to open an unheard of conflict in the FOSS universe.
Update:In consequence of the questions raised in this post I created a petition addressed at Canonical requesting the removal of automatic data collection features.

A last good bye to Paul
Over the years I made a fair good number of "friends" over the internet. I use quotes because these are not the kind of folk you talk to when life is hard or with whom you go for a pint or two after work; most of them live thousands of kilometres away. These are folk with whom I exchange e-mails and forum comments, and by one reason or another mutual respect builds up to the kind of complicity that exists between real friends. I had the fortune to meet a few of them along the years, filling the gaps in my perception of their personality, many times in unexpected, but always positive, ways. But at best I get to see each of these folk once a year.
Earlier this week I learnt that one of my internet friends passed away. It was a news that left a special kind of void and logging in me.

Ubuntu sailing into uncharted waters
Every time a new Ubuntu release is out there is always some controversy on this or that new quirk the developers of this distribution decide to take. With a release cycle of only 6 months that's all to be expected for, if you're willing to use the latest Ubuntu you simply have to accept the fact that you're by default also a tester. That's pretty much one of the tenets of FOSS, more so with a product that tries to be as innovative as Ubuntu. About 18 months ago, when the new desktop environment was introduced a good deal of backlash came up. Indeed the first Unity versions were difficult to understand and buggy; but today, after absorbing its logic and with most bugs dealt with, I can only say it clearly improved my productivity over Gnome 2. That's just the way it is: the latest Ubuntu release is a bleeding edge product and you are part of its maturation process; if you don't like it you can always opt for an older release.
But only one month away from the introduction of Ubuntu 12.10 a new Unity feature has been made public that can potentially change all this.

Loose notes from a conference
Earlier this month I went to an Environmental Modelling conference in Leipzig to present an article on my current professional endeavours. On any field, conferences are mostly important for the networking you build, meeting people from literally all continents and finding new projects to work on. This particular conference was no exception on that regard, but apart from that, there were some interesting points in terms of software worthy of note. Below the fold is a loose collection of thoughts I brought back.

Bundes-Europa oder Tod

Irrespective of her faith in her words, as usual Angela Merkel got the timing wrong. She says the federation has to be built in the next 5 years, but Europe doesn't have even 5 months, it might not even have 5 days. This call for a European Federation should have been issued 4 years ago, in the wake of the credit freeze. The elections in Greece this Sunday may just mark another moment when events overcome Angela Merkel, sending her back to the defensive.

Getting MySQL back after another Ubuntu upgrade mess up

My first reaction was simply to search for available packages, and indeed version 5.5 of MySQL is available in the repositories for this new Ubuntu release. I immediately proceeded to the install command, with it that starting a painful journey to get MySQL back on Ubuntu.

The last ASPO conference

The title "last conference" can be interpreted in varied ways. It can refer simply to the latest, it can also allude to this being the last ever, or even the last I'll ever attend. I haven't quite decided which is it. Below the fold is a short account of my feelings about ASPO 10, may it shed some light on the title.

A Postcard from Portugal
After 7 months in Luxembourg, where my professional carer has been successfully relaunched, I returned to Portugal for this Easter. It was a time to review family and many friends, to rest and see a bit more of a country that can have many good experiences to offer. I brought back mixed feelings, while it is always pleasing to return home, the contact on the flesh with the present social context was rather depressing. Portugal has changed a lot these past months, the crisis has installed itself and spread like the plague. Most folk are being hit one way or the other and families that seemed to be in a comfortable situation when I left are now facing daunting difficulties. This text is a postcard from my visit to Portugal. It has no real photos, like a black and white documentary about war, I prefer using words to paint an hideous scenery.

An obvious path for Science
I got an e-mail today with a link to a fresh publication in the Science journal. It is entitled "Shining Light into Black Boxes" and while it is mostly stating the obvious, it is quite a breakthrough in this sort of journal. Without further ado here's the abstract:
The publication and open exchange of knowledge and material form the backbone of scientific progress and reproducibility and are obligatory for publicly funded research. Despite increasing reliance on computing in every domain of scientific endeavor, the computer source code critical to understanding and evaluating computer programs is commonly withheld, effectively rendering these programs “black boxes” in the research work flow. Exempting from basic publication and disclosure standards such a ubiquitous category of research tool carries substantial negative consequences. Eliminating this disparity will require concerted policy action by funding agencies and journal publishers, as well as changes in the way research institutions receiving public funds manage their intellectual property (IP).Amen.

Operating systems and philosophical users
Small details lost in the rhythm of the days. The many things that a small number cast to the very end of the daily news roll can tell. The following Ubuntu release is coming out in about one month; expectation is growing, especially because this will be a Long Time Support version, in principle somewhat more solid than regular releases, where developers always like to experiment a bit. These days I try to follow the Ubuntusphere a bit closer, in anticipation of what may be in the menu for the 26th of April.
It happens that another piece of software is making some fuss too. It is called Humble Bundle, a set of computer games wrapped in a somewhat childish package. Childish is also a synonym for simple, which permits these humble games to run on toy like gadgetry such as smart-phones. This bundle is not open source, not even free, but you can pay for it whatever you feel is right, and even choose to direct part of your payment to charity.

Net Energy and Time: a critical review
This essay was originally written between December of 2010 and February of 2011. Soon after it was submitted to The Oil Drum, where it underwent a long process of review that greatly improved it; nevertheless it was archived without being ever published. Since its content could have had a negative impact on the scientific career of the folk mentioned, I decided to keep it at bay. One year on it seems now the time to bring it to light.
“Net Energy and Time” is the title of an article by Nate Hagens and Hannes Kunz that attempts to assess how the lifetime of an energy system impacts its EROEI (a digest of this article was published by TheOilDrum). The main objective was to include stochastic risk in EROEI analysis – random or otherwise unpredictable events that may affect the expected output of an energy system. Considering a series of risks of this kind, Nate and Hannes slashed future energy returns, in a way proportional to the system expected lifetime. In parallel, future energy inputs were too reduced as a function of lifetime. The results of this analysis where markedly favourable to Fossil Fuels and especially negative for those systems that require most of the capital investment upfront, as is the case of many Renewable Energies.
This is a review of the “Net Energy and Time” article, pointing the factors that lead to such conclusions.

Trouble with OpenStreetMap
I'm a big fan of OpenStreetMap (OSM), a collective effort to map the world on a voluntary basis. The idea is simple: anyone possessing a georeferencing system can collected data on the various features of their neighbourhood or the places they travel. This data can then be committed to a central repository and made available to everyone else in the world. With time the OSM data base has achieved a remarkable extension, detailing many parts of the world, especially the most populated of those. This data is also served freely by several instances around, you can try it at the project website OpenStreetMaps.org.
For some time I have been using the OSM data as base layer for the web GIS applications I work with, taking advantage of handy libraries like OpenLayers facilitate their use. Especially during prototyping it is quite convenient, but even in later stages can be useful as well, considering the amount of data it provides for some places: buildings, cultural sites, transport infrastructure and more. Recently I employed OSM data on a European wide project focused on urban planning and the outcome was quite unexpected.

Poverty in the USA
The video below contains some unbelievable stuff. Children going to bed without food and folk eating rats. The well established consciously condemning the poor to death. Not really a surprise that is happening in the USA, that democracy where only two parties can win: liberal and even-more-liberal. It is sad, really sad, to see how educated human beings can treat each other.
The home of the brave, where once you loose your job you loose everything else: medical care, home, energy, hot water, mobility, dignity. This is what a country without a Social State looks like, and this is what the liberals are trying to accomplish in Europe, with the tragic help of hesitant and drifting conservatives.

Tactics and Strategy at the Strait of Hormuz

After the Portuguese came the Persians and then the English; the importance of the fortress waned, but of the Strait of Hormuz itself, if anything, it has only increased. Commodities flow in the opposite way these days, but unlike the luxury and exoticism of the past, today they are vital inputs to the world economy.

Mismatch with the Natural Gas Market

And in what is now becoming an yearly routine the gas supplies from Russia got disrupted once more. This time there's no fundamental economic or political dispute, no bad tempered leaders or tough negotiations, it is simply too cold. Russian stakeholders had to choose between honouring their contracts or let their folk die of hypothermia. I guess it wasn't a hard choice.
Nevertheless, some stakeholders seem to be living in a parallel universe, where none of this is real.

Housing in China
For some time there has been this slow, but constant, flow of news on the Chinese housing market. A runaway construction spree that has created entire cities out of nothing, to be left largely empty of people. Days ago a friend sent me a link to the video reproduced below that portraits this reality in detail. The term “ghost city” is not an hyperbole, it really exists in China, and not just in one or two places. This piece can only be classified as a good example of reporting journalism, perhaps rare, but refreshening. Nevertheless, is the Chinese housing market really just a speculative bubble or is there something deeper at work here?

The Hydrogen dream

Cesare Marchetti proposed hydrogen (H2) as a large scale energy vector almost fifty years ago. Then the concern was mainly to find a simple enough way to feed transport systems with what seemed to be a fountain of energy about to come from the expanding Nuclear park. The Nuclear dream is largely gone, but hydrogen lives on. Is it about to come true as a piece in the transition puzzle to a post-fossil fuel world? That's what I was expecting to know.

Chorus: Austerity isn't working

But something less visible has remained from last week's attack: the analysis upon which Standard & Poor's supposedly based its downgrades. The company vised particularly the blind Austerity policy followed by the Council, joining the body of voices claiming it is leading Europe to a dead end. This is an interesting and useful outcome of the unsuccessful strike, that echoed through the last days. Le Monde published a wrap up that is worth looking closer.

Interview with Tarja Cronberg
Below is a video published this morning by the EUObserver with an interview to the Green European Parliament member Tarja Cronberg, who is the head of the Parliamentary Iran delegation and an expert on Nuclear technology. Cronberg is very directly opposed to further sanctions on Iran and seems convinced that it can lead to a military conflict in the Strait of Hormuz. Moreover, she says that harsher sanctions will likely lead to a rally of the population around the present political regime, rather than the weakening of the Ayatollahs' power. Instead of being concerned with particular consequences on the EU states most reliant on Iranian oil, Spain, Italy and Greece, the consequences to the world economy of a conflict around Hormuz can be much deeper and far reaching in her view.
It is good to see politicians thinking outside the box laid down on them by the media, especially by those seeded in the Anglo world. Irrespective of the final outcome of the sanctions being planed it is important to understand that OECD economies will hardly come out of it unscathed.

Oil price forecasts for 2012
This week a friend of mine asked about oil prices for 2012. As usual by this time of the year newspapers and investors alike thrive to have an outlook for the following twelve months, more or less trying to devise how their portfolios may fare. I always find this a bit awkward, the dynamics underlying markets like that of crude oil have little relationship to the rhythm of the Earth's revolution around the Sun. But somehow there is this idea that markets have a sort of fresh start in the beginning of a new year. Hence, usually well informed people put out their forecasts around this time, so as to prove how well informed they are. It just happens that for 2012 the most disparate projections exist, either of a fall in oil prices or of a price boom.
Instead of pointing out who is wrong or is right in this story, the importing thing is to understand that both visions can be correct, both can develop through out 2012.

Video: “You Are Here: The Oil Journey."
Below the fold is a not to be missed video by the Post Carbon Institute. It is a fictional work with an argument written by Richard Heinberg, Peak Oil's proser. A parable of what cheap oil gave to the industrial societies in the XX century and what peak oil may take away in the XXI century. I do not exactly agree with the assessment that alternative energies cannot provide the same sort of services in similar quantities. To my judgement the challenges are much more the social evolutions we'll have to undertake to guarantee that the transition takes place smoothly: a monetary system compliant with an economy that doesn't grow exponentially, adapting markets to favour long term investments, a different concept of mobility, a different kind of agriculture. Cheap oil was good while it lasted, but what may come after it may not necessarily be worse.
In any case, congratulations to the Post Carbon Institute for this excellent effort.

Pre-salt in Angola is for good
A small piece of news quitely surfaced yesterday that could have an important impact on future oil production. Simply put: hydrocarbons where found in pre-salt layers in Angola's waters. This is the confirmation of the expectations some industry agents (especially Petrobras) had built in recent years around the possibility of an Atlantic wide pre-salt resource. The Danish company Maersk was able to recover oil of “good quality” from a well in a block in the Kwanza Basin, part of a joint venture with Sonangol and Svenska (these are blocks that had been commissioned prior to the large auction that took place last month). In its statement to the press Maersk quoted a potential production figure of 3 000 barrels per day from this well.
