  1. Re:Who paid for this study. on Ethanol More Trouble Than It's Worth? · · Score: 1

    Yes, I am very sceptical of this article. I could kind of see ethanol using more energy than it creates, because corn-ethanol is very inefficent, and only exists because of lobbiests, not practical concerns. But when it goes on to say that biodiesal is just as bad, if not worse, my BS detectors went off big time. That has been disproven on many occasion, and with good science mind you, not wishfull-thinking hand-waving. Then they have the gaul to state that solar -> hydrogen is a more realistic alternative? That method of capturing energy from the sun requires significantly more energy than biodeisel!

    I'll have to find the actuall paper when I get off work and see what it really says. I am particlarly curious to see what these unnamed "energy uses not accounted in previous studies" are. Till then I can only speculate about how they came up with the results they did, but I'm definately don't plan on taking this at face value until I've had time to read it, and compare it to other studies.

  2. Re:Why humans have so few genes on Science's 125 Big Questions · · Score: 1

    In addition to lack of mobility, and ability to modify our environment, I think part of the reason we get by with such a small genome may be because we are intellegent. That seems backwards, but think about - plants have to have everything they do hard-coded into their genes. Therefore, they must have all sorts of conditions and exceptions in their genes to survive changing environments, and their existence is just the playing out of those genes. However, humans more than most animals, can learn and think. We have an elaborate unconscious mind that is built from experience as much as from our genes, that replaces much of the special-case heuristics that would otherwise take up space in the genome. And just as importantly, instead of simply acting out our impulses generated by our sense and unconscious mind, we constantly are receiving conflicting impulses which our conscious mind must determine what to do with. While the brain requires some additional genes to create, it would take so much more genes to hard code the same survival ability.

    In other words, our genome contains a small meta-algorithm to life rather than a large dumb spelled-out algorithm. Well, that's my uninformed idea at least :)

  3. No kidding. on Government To Fix Identity Theft? · · Score: 1

    Seeing as how they didn't link to or even cite any of these studies, I think I'll reserve judgment. Half the time the problem with "stupid science" is really stupid journalism. You'll have this perfectly good biology research that looks at how a specific enzyme facilitates a particular aspect of the metabolic system that wasn't completely understood before, and is a good step in the direction of understanding how our bodies work. And how does the news report on it? - "eating fat makes you gain weight". Well no duh. It wasn't that that was interesting, it is the details of how it causes you to gain weight that were meaningfull.

    Furthermore, "common sense" can be used to explain all sorts of conflicting ideas. If the study had come out the other way, everyone would be saying that it's obvious that people are happier if they jump in and try out all sorts of things before settling on what you really want to do - "life is a journey", "you need time to find yourself". Psychology is the study of scientifically testing what common sense ideas about ourselves actually are true, to what extent, and in what situations. Of course some psychologists are better than others, but just because you could have guessed the answer doesn't mean it's not worth finding out for sure.

    There is also a problem with papers written for the sole purpose of getting published, and I don't like that. I wish that more universities would wise up to the fact that knowledge is becoming more and more in-depth and specialized, and therefore it will take longer till someone is far enough along in thier specialty that they can begin doing research that is new and meaningfull. If you force people to write thesis earlier, 90% of them will be rediscovering somthing that has already been discovered.

    But I stand by my statement that stupid jounalism is more of the problem than stupid research, and that knowing something is better than thinking it.

    Corporations are good at one thing: providing goods and services in exchange for money as profitably as they can. They should be held responsible to operate according to the law - ie not to screw people over, but trying to make them responsible for any thing else is foolish and doomed to fail. I don't want the corporations to be responsible for creating/lobbing for labor laws as you suggest - they have a vested interest that may very likely not be in the interest of the workers.

    The same goes for about everything. I don't want them to responsible for protecting the environment - an independent group without vested interests should be doing that. I don't want my employer to be responsible for my retirement - who knows if they will still be around then? I don't want companies responsible for all the things that unions demand out of them - it only burdens them and makes them less competitive abroad.

    If you think that everyone is deserving of some level of pension or health care, then that is a job for the government, not companies. And for any level above that I would much rather be free to choose my own savings and insurance plan on an open market, than be locked into one picked by my employer.

    There is no one institute that is the solution to all our societal needs and problems. The task of providing goods and services as efficiently as possible is beneficial to society in and of itself and the competitive market does a much better job at it than any sort of monopoly, including the government. But corporations suck at other things. Demanding that they take initiative to be socially responsible may satisfy a visceral desire to lash out against them, but it achieves no good practical results. Let the market do what the market is good at, and let the government do what government is good at.

    If I were to complain about this release it would not be because it was not different, but because many of the changes are bad. Scrollbars in a menu? That isn't an issue with lack of polish leading up to the beta release - that is a stupid idea that should have never made it past the design stage.

    Further, history shows that IBM is likely to use a GNU compatible license if they open the source at all.

    Sort of. When they release code added to an existing project, it is released under that projects licence. But most of the code that they have released on their own is under the Common Public License (previously IBM Public License). The CPL is a very nice license, simular to the LGPL in what rights it gives to the user, and the FSF has no philosophical objections with it. However it is not compatable with the GPL for technical legal reasons. That means that you cannot compile GPL(or LGPL) code and CPL code together, although you can link CPL code against LGPL.

    I also agree that it would be very difficult to open source OS/2 because of cross licensing. Just one example - OS/2 is posix compliant. I would be very suprised if IBM did not have some license agreement with the holders of the SVR4 when making the posix layer. Also because they were not planning on releasing the code, they may not have kept track of every location of licensed code. This could become a bigger nightmare then the SCO lawsuit if they tried to open it up.

  22. Re:Sites will just use Reuters for the time being on AP to Charge Members to Post Content Online · · Score: 2, Interesting

    While sites like drudge might switch, I don't think many newspapers would stop using stories from AP just because they have to pay extra to put them online. The larger ones will just pay the license fee and continue. For the smaller ones this will likely be the final straw that makes them realise that their online presence isn't making any money anyway. This will cause them to scale back to just posting local, self-written news or can their website altogether.

    And honestly I think that is inevitable. There simply isn't any demand for hundreds of online news sites that all just regergitate AP and Reuters stories. These newspapers need to realise that once they go online they are competing with every major news source in the world. If they can't provide something unique then they will fail, and deserve to.

    I don't think it's going to be long untill the major wires actually close their content to subscribers only.

    They will only do that when it becomes a viable business model. People keep saying that subscription services cannot be profitable for online news services, because customers will not tolerate them - they will just move to another site. But that is assuming that all of these sites will have the same news - which is only valid so long as the wires maintain a liberal policy regarding posting their content online.

    On the extreme end, if all the wires flat-out prohibited posting of their content online (or make it very expensive), then their online subscription would suddenly be very viable and lucrative. However this might anger the large newpapers enough that they turn to another wire, and therefore it will not happen soon. As (if) the newspapers become shrink in importance (and sales) and online news becomes more important, then the wires will have the motivation and leverage to become more and more restrictive regarding online posting of content. As they do so more and more news sites will die, until the only ones left are the ones that actually create content (wires & analysts), not just regergitate it. At this point subscription would be a viable model for the wires as they are no longer competing with their customers.

    Of course blogs are a possible kink in this scenario. The wires won't be able to shut down every blog that reposts its stories. Will blogs be usefull news sources if they become shut down as soon as they become popular? Will cleverly run blogs be able to get away with rewording every AP article that they post? If so then subscription will not be a viable model for the wires, and things will likely stay just as they are.

  25. Re:AppleDoc rehashed? on Jef Raskin's Humane Interface Released · · Score: 2, Informative

    I think I am correct in assuming that you are referring to the OpenDoc system, which both Apple and IBM worked on.

    This project shares several technical similarities with OpenDoc but it has a significantly different goal. The purpose of the OpenDoc system (and OLE, COM, ActiveX, .NET, KDE KParts, and GNOME Bonobo after it) was to reduce duplicate effort on the behalf of programmers by implementing high level document objects which could be easily reused in applications. This would mean that similar tasks in different applications would be done the same way, because they were using the same code, but you would still have applications.

    Now if this method of programming became widespread, applications would basically just be a bunch of documents object glued together with extra features added - commands and tools that operate on the document object. This project would do away with applications all together, by creating a system framework and graphical shell that provides the "glue" that applications used to. To compare the difference consider a library written in C vs. a set of UNIX command line tools. Both implement the same functionality, both can be save the programmer time in implementing a task, and both can be flexibly combined to do new things. However to you the C library you have to be a programmer, and have to create a library write a full program with its own interface, and finite feature set. With the command line tools, you can right a full program with them (a shell script), but you can also issue the commands in real-time from the shell. With the C library, you have to do extra work to make the application extendable (your own plug-in system), with the command line tools, the ability to add new commands and recombine them in new ways is built into the shell.

    The UNIX shell has limitations though. Its interface and framework (stdin, stdout, pipes, redirect) is primarily useful for filtering documents, not for interactively editing them. Which is why all the unix editors are basically monolithic applications (with their own plug-in and scripting systems).

    The goal of this project to make an operating environment that is more pleasant and powerful to use. It intends to do so by making a graphical shell and system framework that will allow for the developer to make software that consists purely of documents and tools that operate on documents, with no applications to wall things off.

    I hope this explanation is useful - it is a bit abstract, but the details could fill an entire book. In fact they did :)
