J. Karl Rove writes "Nikita Borisov and Ian Goldberg (of many, many other projects) have released Off the Record Messaging for Gaim. Encrypt an IM, prove (at the time) that it came from you, and deny it later. The authentication works only when the message is sent; anybody can forge all the messages he wants afterwards (toolkit included). Captured or archived messages prove nothing. And forward secrecy means Big Brother can't read your messages even if he wiretaps you AND grabs your computer later on. All the gooey goodness of crypto, with none of the consequences! They have a protocol spec, source code, and Debian and Fedora binaries."

A not-so anonymous Anonymous Coward puts this tough issue up for discussion: "There seem some more determined efforts underway currently in some corners of the KDE project to port substantial parts of the software stack to the MS Windows platform. These efforts are now met by fierce resistance on the part of some of their core developers. Aaron J. Seigo summarizes his reasoning in his blog: 'If the applications people want are available on Windows, they will tend to stick with Windows...by porting software to Windows, we eliminate the majority of the competitive advantage of Free Software desktops in the eyes of the overwhelming majority of consumers while Microsoft has all the rope they need to shut the door once again on us ... Free Software desktop applications on Windows represent a no-win situation for Open Source, but Open Source desktops on Free Software operating systems do.'" (Read more below.) "Does it hurt the 'Linux to the Desktops!' battle fanfare, if Linux apps and other OSS are ported on a large-scale to MS Windows, or will it rather have a 'pave the way' effect? Does it help to migrate enterprises and public sector units if users to Linux if users are already familiar with Firefox and OpenOffice.org from Windows, or does it take away the motivation to migrate at all? Is porting Unix desktop software counterproductive? Does it even help Microsoft and damage Windows users?"

Cymage asks: "I usually do my charitable contributions in December, and so I am looking at organizations to give to. I try to give to organizations with different areas of focus. Here are some of the ones I have given to in the past/am considering: Basic Needs (Atlanta) - Food Bank and St Vincent, Promoting Self-Sufficiency - Habitat and Heifer, and Digital Rights/Software - EFF, Mozilla, SourceForge, and BitTorrent. What other organizations, especially technical ones, do you give to and why?"

Martin Ecker writes "Two-dimensional user interfaces (UIs) have been around for a long time, and people are accustomed to using them. However, 3-dimensional user interfaces have not yet received as much exposure. Only a select few applications utilize 3D UIs, some with more success than others. The book 3D User Interfaces: Theory and Practice (published by Addison-Wesley) attempts to give a broad overview of the field of 3D user interfaces. It discusses the hardware devices and the software techniques required to build successful 3D UIs and gives a number of design guidelines to follow when having to develop new 3D interaction techniques for specific applications." Read on for the rest of Ecker's review. 3D User Interfaces: Theory and Practice author Doug A. Bowman, Ernst Kruijff, Joseph J. LaViola Jr., Ivan Poupyrev pages 478 publisher Addison-Wesley Publishing rating 7/10 reviewer Martin Ecker ISBN 0201758679 summary An extensive overview of 3D input and output devices, 3D interaction techniques, and 3D user interfaces.

The book contains 13 chapters, divided into five parts. The first part contains two short chapters that introduce the basic concepts of 3D user interfaces, give a bit of history of 3D UIs, and define the scope of the book.

The second part discusses hardware input and output devices that are useful when developing 3D user interfaces. The first chapter in this part is on output devices and it presents various visual and auditory displays. Haptic devices are also discussed in this chapter. The following chapter presents 2D and 3D input devices that can be used with 3D user interfaces. The devices discussed include not only the classics, such as 2D mice, keyboards, and joysticks, but also 3D mice, tracking devices, and various forms of direct human input, such as via speech or via bioelectric signals.

The third and largest part of the book is on 3D interaction techniques. The first chapter of this part discusses the various ways that have been devised in the past to perform 3D selection and manipulation of objects. A vast number of techniques are presented in this chapter, from various pointing and virtual hand techniques to widgets for rotating an object. The following chapters discuss techniques to allow navigation through virtual worlds and user interfaces, in particular techniques for traveling and pathfinding. The following chapter is on system control and it discusses how to control the system via commands, such as using graphical menus, voice and gestural commands, or real-world tools. Finally, this part of the book contains a chapter on symbolic input, i.e. communicating text or numbers to the system, in the context of 3D UIs.

Part four of the book deals with designing and developing 3D user interfaces. For me, this was the most interesting part of the book because it shows how to put together the various input/output devices and interaction techniques presented in the previous chapters. This part also contains a chapter on evaluation of the design and implementation of user interfaces, an important aspect in order to ensure the usability of a user interface.

In the book's final section, the author takes a look at the future of 3D user interfaces with a focus on the combination of the virtual world with the real world -- so-called augmented or mixed reality. This area has received quite a bit of attention from academic research in recent years.

Throughout the book, there are useful guidelines on designing usable user interfaces. Following these guidelines will probably not give you a perfect 3D user interface, but it will definitely help you avoid the common mistakes and pitfalls. It would have been nice if all the guidelines in the book had been put all together in a separate appendix in addition to having them spread out all over the book.

The book also has a number of images and illustrations. The figures throughout the book are in black and white, apart from a four-page color insert that depicts various hardware input and output devices.

This book contains a lot of information and is probably the most comprehensive book on 3D user interfaces I have seen to date. Pretty much every aspect of 3D UIs is covered in the book somewhere, with some topics being covered in more detail than others. If you're not familiar with 3D UIs at all, this book gives you an excellent introduction to this active field of research. If you are already somewhat familiar with the topic, this book offers you a comprehensive overview of the field and gives you many references to more detailed research articles and papers.

Martin Ecker has been involved in real-time graphics programming for more than 9 years and works as a games developer for arcade games. In his rare spare time he works on a graphics-related open source project called XEngine.

ClintonRNixon writes "A new open-source tabletop RPG has been released, The Shadow of Yesterday. People have been putting RPGs online for free for years, and Wizards of the Coast has their Open Game License, but this is the first time a game has been written and published using only open-source tools, and is published under a Creative Commons license. To make the online version, vi and Python Docutils were used; the published game was laid out using Scribus, The Gimp, and OpenOffice."

Niek writes "The Netherlands Forensic Institute (part of the Dutch Ministry of Justice) has open sourced one of their high-profile software frameworks, TULP2G.

This was previously only possible with commercial software. Dutch press release, Powerpoint presentation. Earlier this year, the Dutch government GPLed their online election software."

Yort asks: "With the Christmas season upon us, it's time to dust off the Yuletide music. However, I'm finding once again this year that I'm needing to re-rip all my CDs to fit the format-of-the-year. Ogg Vorbis for my portable, MP3 for the Tivo, WMA and AAC for sharing with co-workers... Argh! So, I've decided it's time to end the madness: Hard drives are cheap, so I'm going to rip all my music once-and-for-all to a lossless format (I'm choosing FLAC at this point), then just batch convert to whatever format I need. I know I'm hardly the first one to think of this, but I've looked around and haven't found much in the way of good OSS tools for this sort of thing. Any recommendations, or do I have to write one myself?"

ChocLinux writes "A South African organisation has produced what it claims is the first television series dedicated to promoting open source software.

An anonymous reader asks: "70% of my phone bill comes from calls to a few colleagues. We all have 'broadband' internet access (at least 100 kbit/s upstream) and are behind NATs, so we can share our access with the rest of our house-mates. The OS most used is Linux. In order to lower our phone bills I'm looking for a Point-to-Point audio tool which enables you to pass relatively easily through the NATs. I've had a look at Speak-Freely, which is quite nice as it sports things like GPG-encryption. But it uses two UDP and one TCP ports which is a bit much and not very NAT friendly. I wouldn't like to use commercial tools with central servers like Skype. What would be ok is to use a webserver to serve as a kind of starting point where you would update your IP address and ports. But it should be possible to give your mom and pop webhoster to set up or even better just a cgi-script which interacts with the clients via http or https. The audio data itself shouldn't be routed over a server (what a waste of bandwidth). Thanks for all ideas."

An anonymous submitter writes "A few stream-through-firewall applications have been announced recently. p2pnet has an interview with Ian Clarke about his new 'Dijjer' program, which promises to reduce bandwidth requirements from HTTP servers by transparently distributing the load. Slyck.com has an article about LimeWire's new version that offers firewall-to-firewall transfers (code here). [Both Dijjer and LimeWire are GPL'd.] There's also been a lot of discussion on the p2p hackers list about reliable UDP transfers."

Werner Heuser writes "Intel has just released Linux driver version 1.0.0 for the Centrino PRO/Wireless 2100 chipset. Almost two years, since the first Centrino generation with Pentium-M Banias has reached the market, a stable issue of a native Open Source driver has become available. The Wireless LAN driver for the current Centrino generation with Pentium-M Dothan and PRO/Wireless 2200BG chipset is still at version 0.13. This driver is intented to support also the third generation of the Intel miniPCI WLAN adapter named PRO/Wireless 2915ABG. Though Intel intended these projects to be community efforts, there are some possible working constraints. Mainly, no hardware documentation is available."

Nehle asks: "In almost every new multi-player game there is a way of keeping statistics about the games that are being played. Whether it's fan-based services or a service created by the game creator. Unreal Tournament 2004 can write nice HTML files for you, Bungie keep an insane amount of stats about games played over X-Box Live. For my favorite shooter - Enemy Territory, there is an application called Enemy Territory Teamstats and I wrote this little script to keep track of my games. Are stats any important to the average /. reader? Is it interesting how many times you shot 1337h4x0rg4m3r in the head, or is winning all that counts? Do you even want people to know if you lost 14 games in a row?"

Oddly, Microsoft's 2002 'invention' is described in detail in a 1999 listserv post and found its way into scientific journals and other sources before the patent's claims were disclosed. BTW, the patent's term was extended by 269 days, apparently the USPTO's way of apologizing for initially rejecting the patent."

grey writes "The Age has a story up about how the OpenBSD community has been contacting wireless chipset vendors to license their firmware binaries under terms that would allow for free redistribution. This is important, because even with existing GPL and BSD licensed drivers for these chipsets, the drivers don't function without first loading onerously licensed firmware binaries which can only be acquired from the vendor, not shipped by an OSS provider." (Read more, below.)

grey continues "This means that currently, these wireless NIC's don't work out of the box on OSS install or boot media. In just the first 4 days, hundreds of users wrote and called vendors, and already 2 vendors freed their firmware, and several others are in discussions with Theo de Raadt about taking similar steps.

We need your help! TI has still not responded at all. You can call or write to Bill Carney, - Director of Business Development of TI's WNBU to add to the approximately 400 well written messages the OpenBSD community has already sent to TI. We hope that you'll help, and if you do please keep messages polite and to the point. Please remember, we are not asking for the vendors to open source their firmware under the GPL or BSD licenses (though we wouldn't complain if they did). Instead, ask if they would simply email Theo to open discussions on licensing their firmware binaries under terms that allow for free redistribution. If changed, these firmware binaries would then be able to be included with OSS software and function with existing BSD and GPL licensed device drivers from the start.

You can find other contacts for target vendors here, here, here, and here, and it can't hurt to sign this petition. These changes aide all OSS efforts, not just OpenBSD. As you can see from the OpenBSD community's results already, contacting these vendors really does make a difference.

CherryBS writes "The CherryOS emulator, claiming that it could seamlessly run Mac OS X at 80% the speed of the host computer on standard x86 hardware (covered here previously), has created some controversy about stolen code. It turns out that CherryOS's emulation engine is nothing more than that of PearPC, an open source GPL project to create a PowerPC motheboard emulator." Read on for more details.

CherryBS continues "PearPC developers who have seen CherryOS have confirmed it is a fraud, while others remaining anonymous have posted the 'strings' output that CherryOS and PearPC share, showing many function names, warning/informational message strings that exist verbatim in PearPC. Additionally, now-pulled screenshots of CherryOS, mirrored in the long thread at pearpc.net, show CherryOS's boot process revealing variable names and missing or incorrectly emulated hardware in such a way as to be specific to PearPC. Arben Kryeziu, the developer of CherryOS, claims that no code has been taken from PearPC whatsoever, and that he will release a trial version this week. However, with the amount of deception on the part of the company, and considering this wouldn't be the first time he's violated the GPL, it's hard to believe they're telling the truth. Additionally, Kryeziu now claims the "trial" may "disable modules like sound or drag and drop"...likely because PearPC itself does not support such features. To further add to the tale, someone who was likely Arben was specifically asking for video server load testing for their vx30.com video codec/server product, even specifically mentioning slashdot as a great candidate, and in the days following the CherryOS story unfolding, went back and deleted the posts. The first day, all that was left online were two videos, one of which was subsequently removed because of PearPC-specific strings in the boot process shown in the video..."

colonist writes "Tit for Tat, the reigning champion of the Iterated Prisoner's Dilemma Competition, has been defeated by a group of cooperating programs from the University of Southampton. The Prisoner's Dilemma is a game with two players and two possible moves: cooperate or defect. If the two players cooperate, they both have small wins. If one player cooperates and the other defects, the cooperator has a big loss and the defector has a big win. If both players defect, they both have small losses. Tit for Tat cooperates in the first round and imitates its opponent's previous move for the rest of the game. Tit for Tat is similar to the Mutual Assured Destruction strategy used by the two nuclear superpowers during the Cold War. Southampton's programs executed a known series of 5 to 10 moves which allowed them to recognize each other. After recognition, the two Southampton programs became 'master and slave': one program would keep defecting and the other would keep cooperating. If a Southampton program determined that another program was non-Southampton, it would defect."

According to an InternetNews report, they are using Wix to convert the MSI file designed using InstallShield into XML to achieve greater control over the installer. Of course, they are simply using it because it's Open Source (CPL license) and in good faith. Earlier this year, when Microsoft surprised everybody by releasing the Wix project under an open source license, some were cautious about using it, as the specific XML schema it uses might be patented just like the Office xml schema. Whatever.. Rob Mensching, Wix's lead developer, is very happy about MySQL choosing to use Wix for their installer."

Switching (Score:5, Interesting) by MikeMack (788889)

If I was a Republican or Democrat, what would you say to me to make me switch to the Green Party?

The Green Party offers both Republicans and Democrats the true essence of what each of their parties should be. For Republicans, the Greens offer true conservatism, which means keeping the government out of your personal business, out of your bedroom and out of your library. A true conservative would never support the so-called "Patriot Act;" nor would a true patriot for that matter. A true political conservative would recognize that public resources, such as forests, parks and oceans, should be conserved for use and enjoyment by future generations.

For Democrats, Greens are the party which champions what Democrats used to: support for working people and people of color and protection of the environment.

Both Democrats and Republicans don't represent the people of this country, they represent the transnational corporations who line their pockets and make their election to public office possible.

How do you avoid corruption? (Score:5, Interesting) by kwiqsilver (585008)

It's commonly accepted that power corrupts politicians. The Greens are always speaking out against politicians who sell favors to their corporate buddies or other special interests. But the Green party also espouses a system where the government strictly regulates most industry. How do you propose to have such strong government controlled regulation, without falling victim to the corruption inherent in a bureaucratic system?

The bureaucratic system may well be corrupt but what we really need to address is the corruption in the White House and in Congress-that's who makes the laws and the decisions which support the transnational corporate empire. The halls of Congress are filled with lobbyists representing the international profiteers who play Congress like puppets on strings. Although, I suppose, instead of strings it's campaign contributions which make the puppets dance.

If we take the private money out of our public elections and away from our public officials, we'll go a long way in addressing corruption and ensuring that we truly have a government by the people. We also need to strengthen public meeting laws so Dick Cheney and Enron can never again meet in private to determine the energy needs of this country. We also have to stop the revolving door between industry, Congress and the White House. There have to be much tighter restrictions on public servants going over to private industry.

Here goes again (Score:5, Insightful) by MORTAR_COMBAT! (589963)

I'll ask the same questions I posed to the Libertarian candidate:

Would you approve of, and what would you think would be the results of, the following election reforms:

1. Abolition of electoral college, president is elected by simple popular vote.

The Electoral College is an historical, anti-democratic and racist anachronism which needs to be abolished. If you're wondering why it is racist, remember that when it was created, slaves were counted as three-fifths of a person to determine representation, yet they couldn't vote. Therefore, slave states had greater representation in the Electoral College-as if counting any human being as a portion of person wasn't insulting enough.

However, replacing the Electoral College with what you call a "simple popular vote" really doesn't go far enough. We need to replace it with Instant Runoff Voting to ensure that the winner of the popular vote wins with a majority of that vote. Instant Runoff Voting is a voting system, used to elect the mayor of London, the president of Ireland and many office-holders in Australia, which allows you to rank candidates in order of preference. If someone wins a majority of first choice votes, the election is over. If no one wins in the first round, the candidate with the fewest first choice votes is eliminated and a runoff is held instantly taking into account the second choice votes of people who voted for the eliminated candidates.

Instant Runoff Voting will be used in San Francisco this November and a number of other cities and counties have approved of using it or are considering doing so. Instant Runoff Voting, or IRV, solves the perceived "spoiler" problem because you can vote for all the candidates you like; you don't have to make a lesser-evil choice. I encourage people to learn more about IRV at Center for Voting and Democracy.

2. Federal mandate that electoral votes from a state be split proportional to the popular vote within that state. (e.g. if California splits 60-40 Kerry-Bush, then their electoral votes are split 60-40 as well). This helps move away from the very brittle "all or nothing" electoral system, where as few as 1 fraudulent or defrauded vote can change the outcome of the national election for president.

I believe we should move rapidly towards Instant Runoff Voting, as outlined above, rather than tinker with an anachronistic relic.

3. Constitutional amendment granting naturalised citizens the eligibility to run for president or vice president. This would allow for the 2008 ticket for the new political party, C.O.P. (Cast Of Predator) to field Arnold Schwartzeneggar and Jesse Venutra as their presidential ticket.

Democracy should be as inclusive as possible. While I don't necessarily find myself opposed to this proposed amendment, I believe there are much more profound and necessary reforms, such as Instant Runoff Voting and proportional representation, where we should focus our energy and attention.

Our country is made up of immigrants. Your place of birth should not disqualify someone from serving as president or vice president.

Lastly a question: is the democratic system as instituted in the United States hopelessly mired in a two-party stranglehold, leaving corporate interest in defacto charge of the discussion? Is legal election reform necessary, or even possible?

Election reform is absolutely necessary, it is possible and we are being successful in changing our system for the better. Instant Runoff Voting is part of the equation. So are open and unrestricted debates, free media for candidates on the public airwaves which we own, less burdensome access to the ballot, proportional representation and public financing of campaigns. A number of states, including Maine, Massachusetts and Arizona, have been successful in implementing campaign finance reform.

We also have to strike right at the heart of the corporate empire and rescind the human rights which have mistakenly been conferred on corporations.

Voting Rights for Noncitizens? (Score:5, Interesting)by anzha (138288)

Thank you for your time. Recently in San Francisco, Matt Gonzalez, a popular local Green Party politico, has been pushing for the ability for noncitizens to vote in some of the local elections. While there are other places that offer this long before SF, it seems as though this erodes the differences between having citizenship or not. Rather than expanding the franchise this way, why not work to streamline the process for getting citizenship and encourage people to seek it?

Can you expound and explain a bit on your stance on this?

Matt Gonzalez has championed the ability of non-citizens who have kids in school to be able to vote in School Board elections. This makes sense and we should support it.

I would like to see the process streamlined so that undocumented workers, who are here and are paying taxes and contributing to our society, can obtain citizenship more simply and easily. We have to remember that we are all immigrants or the children of immigrants, with, of course, the exception of the Native people of this continent.

Greens work both within and outside of the electoral system for genuine democracy, social and racial justice, a healthy environment and for peace and non-violence. We have to march both in the streets and into the ballot box. If we do one and not the other, we won't be successful. All great social movements have used this approach.

Greens believe in freedom and privacy. We support same-sex marriage and reproductive choice.

Copyright and Digital Law (Score:5, Interesting) by Nick Fury (624480)

Obviously we here at slashdot are a bit on the techie side. I know that I have personally watched my rights being taken away from me over the past few years. Mainly my right to fair use. Under current law it is illegal to watch CSS encoded DVDs under Linux or any other Open Source operating system. What are you and your party's feelings on loosening certain restrictions to make the act of fair use a right again.

Also, on the concept of intellectual property and copyright laws. What are your party's and your feelings on the current trend of extending the length of copyright terms? Do you have any plans to reverse the current trend or perhaps to set the lengths back to their original terms?

Nick, first let's look at what the Green Party's platform says about open source: copyrights:

"10. The Green Party supports protection of software (free or proprietary) by means of the copyright. We strongly oppose granting of software patents. Mathematical algorithms are discovered, not invented, by humans; therefore, they are not patentable. The overwhelming majority of software patents cover algorithms and should never have been awarded, or they cover message formats of some kind, which are essentially arbitrary. Format patents only exist to restrain competition, and the harm falls disproportionately on programmers who work independently or for the smallest employers."

Greens favor information flows that come from the grassroots and empower the grassroots. Excellent examples include free/open-source software, open document formats, and the Creative Commons Licenses. We recognize that creativity and productiveness do not exist in a vacuum. Rather, most innovations build on earlier innovations. Creators and producers should be entitled to seek financial compensation for their work - or not, as they choose - but to wall their work off from public access for unreasonable lengths of time is, well, unreasonable.

For most of the history of the US Patents and Copyrights Office, most patent applications were denied. Most "inventions" didn't meet the triple test of being novel, useful/valuable, and not obvious to "someone skilled in the art." Patents that were granted lasted 12 years which was considered to be a third of an invention's useful life. Today, the patent office rubber stamps just about anything. We don't need a new policy, we need the old policy. Let's give standing to all stakeholders to challenge and strike down mistaken or overly broad patents, or patents granted despite the existence of prior art. (Besides genetic patents being a particularly vile abuse of corporate power, genes are, by definition, prior art. We oppose the genetic modification of organisms, as well, but that's another topic.) There's also a place for an eminent domain process for striking down a patent when there is an overriding public interest, as in the case of absurdly overpriced life-saving drugs.

In copyrights, as in patents, we favor not a new policy, but a return to the original, which provided for protection for 20 years.

If we get the general principle right, we won't need a special policy for protecting proprietary digital artworks or people's right to make fair use copies of them. But we do need a prohibition on abusive license agreements. The case law striking down "shrink wrap licenses" should be legislated. A valid contract provides an equal exchange of value: It's not all prohibitions on one party while the other party has no obligations and retains all rights. It shouldn't be legal for Microsoft, for example, to license its OS for use on only one particular CPU. That is, you shouldn't have to buy a new copy of XP when you upgrade your motherboard. When you buy a movie on DVD you should be allowed to play it on any DVD player, and when you buy a copy of an OS you should be allowed to run it on all your computers. This should be a natural result of a more general prohibition on unfair contracts.

Three Contentious Technologies (Score:5, Interesting) by rumblin'rabbit (711865)

Here are three technologies which environmental groups have generally been opposed to, but which have undergone major advancements in recent years: * Nuclear energy. * High-temperature garbage incineration. * Genetically modified foods.

All of these technologies have drawbacks, but they also have many advantages over the alternatives. Nuclear energy does not produce greenhouse gases, incineration destroys toxic chemicals and does not require land fill, and GM foods can greatly reduce the amounts of pesticide, herbicide, fertilizer, or water needed to grow food.

What is the Green Parties' stance on these, and do you see them changing their stance in the near future?

Greens have moved beyond a lesser-evil approach to politics as well as to the issues you describe above. I cannot under any circumstances accept nuclear power and genetically modified foods as a healthy alternative. There are such simpler and more sensible ways to approach these issues. We could easily eliminate the need for nuclear power by conserving more energy. We could replace nuclear power-and coal and other dirty forms of producing power-with the abundance of solar energy which shines on our country. Wind turbines, like the one I visited in Nebraska recently, are also part of the solution.

Food was grown by humankind for an awfully long time and rather successfully before the advent of pesticides and herbicides. We don't need that poison on our foods, on our soil or in our water supplies. And we don't need Frankenfood either.

As to our shortage of landfill space, we need to increase recycling and require manufacturers to take material back if it is not completely recyclable or biodegradable.

Furthermore, How will you deal with our budget deficit and reform the GOP's relentless tax cuts and the Democratic Party's exorbanent spending?

Marijuana has been declared by an Administrative Judge for the FDA as one of the safest therapeutic substances known. I fully support the right of physicians and patients to use what they deem best for treatment.

The "war on drugs" is racist and an insult to all Americans. This "war" has incarcerated people of color at a much higher rate than white people. It has resulted in senseless attacks on innocent people and on our Constitution. We have to treat drug addiction as a health problem, not as a crime.

The main contributing factor to our national deficit is the world's largest military budget. The Green Party supports closing overseas military bases and reducing the military budget by 50% over ten years.

Single Payer Healthcare (Score:4, Interesting) by Coryoth (254751)

You often point out that pretty much every developed western country except the US has some form of single payer healthcare, and I think it is a valid issue, worth dicussing. However, having lived in a few countries that operate such a system I have generally found the governments involved to be having difficulties sustaining the system.

"The dilemma amounts to this: as medical science continues to advance, and as we in general live longer and longer, the amount of things that can be done continues to expand, along with the costs involved with any new technologically advanced treatments. Because of this, the costs of providing complete healthcare continue to expand at a rate faster than we can pay for. With healthcare, if something is possible, people tend to demand that it be done, even if we do not have the resources to do it.

Complete provision of healthcare simply isn't a sustainable practice as the costs are not proportionally bound by population (and hence very roughly speaking, government income), but instead by the ever expanding limits of medical science.

How do you intend to deal with this dilemma? Do you only plan to provide single payer healthcare for core and emergency services only? Do you intend to allow a parallel private health system to provide the more expensive treatments?

The basic point of single payer is that it is cheaper to administer and also that the cost of pharmaceuticals are lower as a result of bulk purchase. It is true what you say, the costs of medical care will increase in all countries as a result of innovation. However, empirical evidence shows that they will increase far less in countries that employ single payer. The best example is that of Canada and the U.S. When Canada enacted single payer their health care costs were the same percent of GDP as the U.S. Now, some 30 years later, they spend 8.9% while we spend close to15% of GDP. They spend much less in Canada on health care while treatment outcomes are similar overall in both countries.

Besides, we could pay for lifelong health care for every citizen in this country, along with college tuition for everyone who wanted to attend universities, if we stopped waging war in Iraq and Afghanistan and cut 50% from the biggest and most bloated military budget in the history of our planet. We could also do a much better job of focusing on preventative measures and take special care of infants and pregnant women, thereby ensuring a healthier start to life and reducing costs later on.

We are not opposed to allowing a private system to offer services not covered by a public system, such as Canada does. However, it is our intention to offer a comprehensive health care system which includes outpatient, inpatient, medication, dental, mental health and long term care, as research shows that this is both the most efficient and effective means for delivering health care to our population.

Viable Third-parties (Score:5, Interesting) by thewiz (24994)

Mr. Cobb, What do you believe is necessary for your party or any other to become a viable third party in American elections? Even though George Washington warned against having a partisan political system in his farewell speech, America seems to have developed a two-party system that forces third-parties out of the political process.

Also, what do you think of the Democratic and Republican parties shift away from what's good for America toward what is good for their respective parties and the businesses / people that support them while leaving the majority of Americans out?.

The need for a viable third party-or a second one, given the similarities between the two old establishment parties-is obvious and dire. We need a viable political alternative because thousands of innocent civilians and hundreds of young American kids have been killed in Iraq and Afghanistan. We need a viable political alternative because we are the only industrialized nation which doesn't provide health care for its citizens. We need a viable political alternative because our country is addicted to fossil fuel and will literally kill to sustain this addiction. We need an alternative because both of the old parties support the expensive and failed "war on drugs." We need an alternative because they are more intent on building prisons than schools; because they conspired to pass the unconstitutional civil liberty-threatening "Patriot" Act and because we need to develop a solar-based economy and create family wage jobs.

We need a viable political alternative because we need to manufacture democracy here at home before we can export it.

We don't have a "two party system" so much as we have an electoral system which favors two center-right political parties. And those two parties have done everything in their power to maintain their power and eliminate, ridicule and harass the competition.

To establish viable political alternatives, we first have to create a genuine democracy. Let's remember that this country was founded by rich, white landowners for their benefit. Our founders did not create a democracy. "The people" did not-and still don't-elect the president or the judiciary. Only the House of Representatives was elected by the people when this country was founded and those people were not women or people of color or the poor.

Our democracy is evolving and we still have a long ways to go. We need to get private money out of public elections and public policy. We can't have Enron and Dick Cheney's friends writing our energy policies in secret. We need to open up the whole process including how we make decisions on who will represent us. We need to have presidential debates open to all candidates on enough ballots to win the presidency. We need to address our voter participation rates which are among the lowest of any democracy.

I'm glad to see that we are making inroads with Instant Runoff Voting which will be used this fall in San Francisco's city elections. Instant Runoff Voting is a voting method which eliminates the perceived "spoiler" problem and ensures that the winner of an election has the support of a majority of voters. Our last three presidential elections were won with less than a majority vote. Instant Runoff Voting solves this problem and allows you to vote your hopes instead of your fears.

Most democracies use proportional representation to elect their legislatures. Countries which use proportional representation have a much broader representation of political parties and also have greater representation by women and higher voter turnout.

Of course, first a party has to get on the ballot in the first place and here again, the U.S. is light years behind the rest of the world. The United States is the only country where someone has to comply with 51 different and separate requirements to run for national office.

We also have to address the corporate control of the media. It's gotten to the point where, literally, a handful of companies control everything most people see and hear on the radio, on television and in the movies. We, the people, need to reclaim our public airwaves and we need to support our local, grassroots broadcasters.

Green activists are working on all these issues and, with San Francisco as just one example, we are succeeding, even if success is often incremental and not as quick as we would like. These issues also provide an opportunity to work in coalition with other political parties, concerned citizens and "good government" organizations.

To address your other question, I'm not sure that the two old parties actually ever represented the people. As long as there have been powerful, monied interests in this country, they have had their servants in Washington, D.C.

The Green Party is beholden to no one except the people. That, above all else, is what makes us unique.

In the words of Tip O'Neill, "All politics is local".

What is this desire to aim directly for the Whitehouse? Why not pool resources and fight the local battles? By aiming for the presidency (and ignoring the local politics), you are setting yourselves up for a fall. We all know that in a 2-party system, rigged the way it is, your chances of winning the Whitehouse are somewhere between 0.00 and 0.000. Then why waste the resources on this race?

How many members of Congress do you have? How many locally elected officials does the Green Party have? How many judicial appointees do you have? See the pattern here?

Maybe this isn't a question as much as a rant, but if you feel like, please answer why you are wasting the time and effort on a run for the Whitehouse, when the same resources, applied at local levels, would yield immensely more benefit.

I'm glad you asked this question because many people are not aware of the fact that the Greens have elected hundreds of local officials all across this country, including Green judges. We have elected city and county councilors, school board members, soil and water conservation board members, mayors and members of state legislatures. And that's just in this country. The Green Party is an international movement and around the world we have elected members to over two dozen national legislatures and parliaments. We haven't yet elected a member of congress in this country but we will. We are getting bigger, stronger and better organized in each election cycle. We are the fastest growing political party in America.

One of the reasons why we are the fastest growing party in America is because we participate in presidential elections. Like it or not, much of the nation-indeed the world-focuses on our presidential election. One of the main reasons I'm running is to continue to build the Green Party; to register more Green voters and especially to support local candidates. Running a national and a multitude of local races are not mutually exclusive endeavors. They are actually symbiotic and each enforces and supports the other.

In this election, the Cobb-LaMarche campaign is the only campaign which supports a genuine, progressive agenda for change and which will continue building a movement beyond Election Day. Greens are in this for the long haul. What we are trying to accomplish is greater than any one candidate or any single election.
