Evaporation Prevention Using Molecular Blankets

Makarand writes "According to this article in the New Scientist, a Canadian company is testing a technology to reduce water evaporation from reservoirs by spreading an ultra-thin blanket of organic molecules on the surface to block the escape of water molecules into the air. Trials conducted in India and Morocco showed between 30 and 45 per cent reduction in evaporation using this method. However, the long term ecological effects of reducing evaporation in lakes or reservoirs is not yet clear as evaporation prevention can increase water temperatures and affect the exchange rates of gases such as oxygen, nitrogen and carbon dioxide."

    Eric S. Raymond, self-appointed historian/custodian of hacker culture and inventor of the "official" logo for said culture, a libertarian, "gun nut", neo-pagan, musician, open-source developer, fetchmail maintainer, LARP-er, warblogger, and anti-censorship activist. Surprising however is the claim to be a libertarian, and yet at the same time praise both Bush, the war on terror, and the blatant violations of international law in pursuit of the WOT.

    Certainly an accomplished and diverse resume. Certainly an unconventional person by anyone's measure. I for one appreciate and commend ESR for his many contributions to the "hacker" culture that I consider myself to be somewhat a part of, although I disagree with the terminology and some of the widely held beliefs of said culture. There is no doubt that Eric has been a valuable member of our community, certainly The Cathedral and the Bazaar and his lobbying of Netscape were large steps forward for the open-source movement. There are those who view these important contributions with less appreciation that I, and ESR has his foes among our movement, of that we can be certain, but the general consensus is that he has added greatly to that which we cherish.

    Now however, even more than ever we have begun to see Raymond take the path of those who seek fame and power more than the ability to serve and contribute. Claims of egotistical behavior and power-hungry publicity tactics are more the norm than the praise of the past. Resentment and revulsion have become the typical reactions among many here and elsewhere. Why is it that we are more likely to see unchecked trolling against ESR than any other in our community save perhaps Stallman? I will present the facts and background that will inform you the reader of the self-absorbed and uncompromising views of Eric S. Raymond. To take a cheap and easy shot, I would say that it is an ugly picture, even more so than the portrait of the man himself.

    Let us begin with what seems to be the most specific and common complaint against the man, his usurpation of the Jargon File, the dictionary of hacker culture. Disregarding those who are angered merely at the fact that ESR has taken the Jargon File as his own and removed some of the older terms, many have railed against him for molding the File in his own image. We will also disregard terms such as "Aunt Tilly", that although not used widely if at all by any hackers at all save Raymond and a handful of others is not an entirely unfit term for the File, as it originated on the LKML and some feel it is fit for inclusion. Instead I will cite the three massively unfit terms that Raymond has chosen to enter into the "offical" lexicon of hacker-dom, "GandhiCon", "anti-idiotarianism" and "fisking". GandhiCon - 386 hits on google. I have found that ESR is the main user of this term, and seems to be it's originator. Other than ESR this term seems to be limited to those who have read ESR's writings on the subject and wish to imitate him. Hardly a widespread "hacker" term by anyone's measure. However I am willing to concede this addition on the basis that at least it deals with issues central to the open-source movement, others are more up in arms over it's usage than I, but I appreciate that this particular term actually could be a candidate for inclusion in the Jargon File.

    The other two additions are more troubling, and are nothing more than pet terms of ESR himself and his personal ideology and habits, which I will delve into further into this post. Anti-idiotarianism - supposedly "very common" according to ESR's entry. This entry is far beyond grips with things like "Aunt Tilly". Anti-idiotarianism refers mostly to ESR's own screed on the subject, "The Anti-Idiotarianism Manifesto". A document that highlights ESR's own personal politics and attempts to bash multiple groups of people. Simply search for this term to find out the depths of of his political views. This political term that describes ESR's own writings has no place in the Jargon File, as is the case for fiskin

    The latest violence comes amid increasingly bleak assessments from Washington, where the latest attacks have been compared in the media to Vietnam's 1968 Tet Offensive against US forces

    That is, actually, an interesting quote although in a different context than the author of the article intended.

    The Tet Offensive was an unmitigated military disaster by the NVA. All attacks were repulsed by the US troops at a horrible cost to the attackers. It was also a major disaster when it came to politics. North Vietnamese leaders wished to raise a nationwide popular uprising that would drive the capitalists and their South Vietnamese "puppets" into the sea.

    Why was it such a turning-point then? Because of the media - both international and US. The Vietnam war was the first televised war. When the audience saw young soldiers exibiting the signs of combat stress, crawling in dirt and dying, it gave the impression that the US forces were losing the war. In fact, the reverse was true. Before the Tet offensive the NVA was almost smashed and the casualties inflicted by the Americans during Tet made it even worse.

    What broke was the morale at home and it was broken by the sensationalistic media. Even worse, something similar is certainly happening in Iraq as we speak.

    I'm curious why this had to be tested in India and Morocco. I don't know if it's the case here, but I get really sick of things being tested in far away places, apparently because the lives of the people who live there are not valued as high as those of westerners. Remember Mururoa?
