Mincipal Wifi’s

February 24th, 2005

From the NYTimes reporting on Philadephia’s attempt at a municipality–wide wireless Internet network:

“City officials envision a seamless mesh of broadband signals that will enable the police to download mug shots as they race to crime scenes in their patrol cars, allow truck drivers to maintain Internet access to inventories as they roam the city, and perhaps most important, let students and low-income residents get on the net.”

Municipal wireless is at the same time a fascinating experiment in technology diffusion, a scary story of surveillance, an interesting battle between the public and private sectors over who should build the infrastructure and finally, an example of overlaying virtual public space over physical public space at 1:1 scale. As much as I love wireless, I’m not certain it’s a good idea to have my nose buried in a laptop instead of occasionally experiencing the world around me (at minimum, I’d likely bump into the lamposts). But then again, is it any different from the continual connection to the virtual afforded by cellphones and Blackberries?

Wi-fi Networking News has a good round up on munipical inititiatives to create wireless communities.

Legal actions to halt innovation

February 24th, 2005

Prevailing myths about computers hold that technological innovations epitomize progress, which are both desirable and inevitable. Next week in class, we’ll wonder out loud whether the inevitable thrust of progress is such a good idea, particularly when it seems devoid of any precautionary principle. But how comfortable do we really feel about halting progress? Consider this article from the The Washington Post, which asks: How should courts view technologies that have beneficial uses but also are heavily used for illegal acts?

Next month, the U.S. Supreme Court is scheduled to hear arguments on whether a file-sharing service named Grokster should be held liable for the millions of people around the world who use it to illegally trade music, movies and software.

The entertainment industry is asking the court to rule that even though Grokster itself does not engage in stealing files, the service is responsible because it is predominantly used for theft and has done nothing to try to stop that use.

The prospect that the court might adopt this legal reasoning is sending shudders through the technology and consumer electronics communities. Hundreds of existing products could be threatened, they say. And they fear that new products, and early funding, will die in the crib if the gear might be co-opted by people wishing to use it improperly.

“If it’s so risky for me to try out new things or put new things on the market, you are really going to devastate people’s willingness to innovate,” said Elliott Frutkin, chief executive of Time Trax Technologies Corp., a Gaithersburg start-up.

For those of us who love our iPods, peer-to-peer software, and Tivo, can we be so quick to condemn progress? That is the conundrum for our-technology-loving culture.

Asbestos & Canada

February 24th, 2005

There was an interesting reportage on radio-canada (cbc in french) on friday night about asbestos & canada. I found that the attitude of Canadian government and companies towards asbestos was the same “kind” of attitude than the one towards Basel treaty. Here’s some interesting facts that I noted from the reportage:

* Asbestos is recognized as hazardous and a threat for public health by all western countries except Canada.

* Some scientific studies show that with appropriate care, asbestos can be safe.

* The form of cancer due to asbestos takes 20-30 years to develop.

* The european union has recently banned asbestos completely.

* Canada blindly exports its asbestos to developing countries where they don’t take appropriate safety measures to handle it. Huge outbreaks of cancers due to asbestos are predicted in these countries (china, thailand,…).

* Other western countries accused canada of using its “good” image and being hypocrites towards developing countries.

* To be consistant and answer others accusations, canada lifted some restrictions on asbestos in canada… so now we put it everywhere in our roads. The government even considered put it in the parliement… but they backed off.

* If Quebec would be a country it would be the country with the highest rate of cancers directly linked to asbestos

* All the asbestos industry is in quebec and it’s worth about $160,000,000. It employs about 1000 persons only 4 months per year.

* Asbestos lobby would be one of the strongest, similar to tobacco lobby.

So basically the conclusion of the reportage was that we risk our own health, the health of thousands of construction workers in developping countries, the international credibility of canada… all this for saving that industry. And you can also do the maths:

+$160,000,000
– $(the welfare of the 1000 employees for the 8 months they don’t work)
– $(the medical cost for cancers)
– $(CSST cost)
– $(the indemnities for the relatives of the ones who die of that cancer)
– $(the cost of the agency that promotes asbestos)
==============================
Is it really worth it????

Someone keeps stealing my letters…

February 23rd, 2005

I’m not sure how many of you have had to deal with online communities, but one of the things holding them back definitely seems to be that a certain segment of people seem to be far more willing to be… unpleasant, when they feel anonymous. Spam is another branch in the same family, if the people sending all those e-mails, or running the bots which spam blogs and public forums actually knew the people using the forums/e-mail/etc, you can bet they’d think twice before they ran amok.

What brought this on is the following website: Someone keeps stealing my letters…

It’s pretty frustrating, there seems to be a high number of people who exist simply to try and mess up what other people are doing… I very nearly had a nifty sentence before someone came in and decided to wreck it. In fridges with more than say 20 people, it’s impossible to write anything at all.

Chicken feathers in computer circuit boards

February 22nd, 2005

Today in Wired there is an article about a researcher from the university of Delaware that is currently investigating the possibility to use chicken feathers and soybean oil in the circuit board manufacturing process, the soybean oil to replace the epoxy and chicken feathers to replace the fiberglass. In addition to the fact that it would be environmentally friendlier it would have the following advantages:
– There are a plenty of feathers available and mainly used for low-grade animal feed for cattle.
– Farmer could make more money out of their chickens.
– “It lightens the weight of the composite and creates an environment conducive to high-speed circuits.”

Informal Education in Florida

February 22nd, 2005

You’ll all be happy to know that I visited a small museum with an interactive computer exhibit that told me all about the flora and fauna of the park we were in as well as the hiking trails I could choose to walk on.

In the Everglades interp centre today there was a computer telling me all about the mosquitoes in the area!

I have yet to go on an interpretive program, but have seen a couple rangers straying around the areas we have visited. the museum and interp centre there were also some examples of more conventional non-personal educational media – such as a board with several swatches of animal pelts asking the visitor to decide which animal each pelt belonged to.

This will be interesting to look into… but I know I was more captivated by the computer exhibit than a poster on the wall, maybe not more than the pelt guessing game though! and it will be interesting to see how effective an interpretive program is compared to the computerized exhibits!

hello from gator land

February 22nd, 2005

People and nature:

This will be short and sweet as internet time in hostels is precious! Today we were in Everglades National Park! There were alligators EVERYWHERE! They were sunning themselves right up on the walking path. We saw at least 5 or 6 within 100m. There were parents who were asking their kids to move closer and closer to a gator so they could get a really cool picture! Can you believe that? Why doesn’t society, in general, have a greater appreciation for wild forces, such as the alligator? and why is it that the alligator didn’t just snap at that child?

Well, western humans have done a pretty good job of learning how to dominate just about any situation – and since that gator wasn’t offering any resistence to the humans, they just kept dominating! The gators on the other hand are probably used to hoards of humans walking by everyday and taking pictures non-stop!

Spam escalated

February 21st, 2005

The spam has accelerated in the past day. And it has reached a level of sophisticaton that the spam prevention aspects of wordpress cannot easy detect it. Therefore we have to moderate the comments. So be patient with us if your comments do not appear immediately.

SHA-1 kracked!

February 21st, 2005

Another encryption method bites the dust

This is HUGE for the digital security world! The SHA-1 encryption method is a ubiquitous standard used in almost every server software, web browser, online shopping system… the list goes on!

Here is a link to Bruce Schneier’s blog where he was the first to report this development.

Google modifying webpages

February 21st, 2005

Here is a story about a new feature Google is offering on its toolbar whereby links are automatically inserted into webpages you are looking at. For example, you might be reading about a certain book and the Google program running in the background will place a link to Amazon.com in the webpage. Seems like a convenient feature but what about the publisher or creator of the webpage you are looking at? Don’t they have the right to control how the page looks? Or should you the user be free to modify it however you like? There’s somewhat of a controversy brewing over these issues.

HTML is inherently a client-side layout system, meaning the browser interprets the HTML and presents it a certain way. There really isn’t any way for webpage designers to know for sure how their pages will look on the other side. But is this new feature going too far? The article I’m linking to makes the interesting point that if Microsoft or Oracle or some other huge and less-loved company were doing this, the world would be up in arms.

The skycar

February 20th, 2005

Don’t know if you had ever heard of the skycar (Moller has been working on it since 1962) but I hadn’t until yesterday when one of my friend who is doing a business case study on it talked to me about it.
The skycar is a “personal vertical takeoff and landing (VTOL) vehicle”. Their latest model can take up to 4 passengers, has a cruise speed of 315mph, a maximum range of 750 miles and a fuel efficiency of ~=20mpg, equivalent to the fuel consuption of a big SUV. The company claims it can burn any available fuel from diesel to natural gas. Considering it can burn 15.75 gallon of fuel per hour, I hope that by the time everyone has its skycar, its efficiency will be improved.
For the moment you can already put a $100,000 deposit to secure one of the 100 first skycar listed at $995,000 each.

PS: Mmmmh this might explain a lot of things about ufos :o).

Economics of climate change

February 20th, 2005

Big feature in the Globe yesterday on the economic impacts of climate change. Some major institutional investors such as pension plans and retirement funds are asking the companies they invest in tough questions about their ‘risk exposure’ to Kyoto. They want to know how much the companies will have to spend in the future to reduce emissions, how well they are positioned to deal with shifts to alternative energy sources, and what the economic consequences will be to their investments. I think it’s quite promising to see the investment and business community ratcheting up their discource on Kyoto; it almost makes it seem like they realize it’s something they’ll have to deal with whether they like it or not.

There’s a sidebar about green investing. I know most students don’t have much money to invest but it’s still interesting to read about some of the supposedly socially/environmentally responsible investments out there.

Artificial intelligence and the environment

February 20th, 2005

The NYTimes today has an article on the future of war fought with artificial intelligence, “a 21st-century fighting force of automated tanks, helicopters and planes, remote missile launchers and even troops of robot soldiers – all coordinated by a self-configuring network of satellites, sensors and supercomputers.”

This is little different from the myriad computer models and satellite photos with which we make life-and-death decisions about the environment. Protect this habitat here. Put that dam in there. The NYTimes article reminds us of the conundrum inherent in leaving everything to the computer:

The whole point of automation is to rise above human fallibility – knee-jerk decisions, misunderstood orders, cowardly retreats. Machines are faster, more focused, impermeable to propaganda and, at least for now, they don’t talk back.

As the thinking machinery continues to evolve, the strategists will keep asking themselves the same question: Is there still a good reason to trust ourselves or should we defer to a computer’s calculations?

In other words, is it better to model the environment or better to walk in the woods? Base judgements on our spiritual connections to nature or let the computer determine the optimal solution? If nature is socially constructed, that is an individual’s mental vision built up of past experiences, biases and culture, then whom/what should we believe? Would a computer be less biased?

Podcasting the environment

Recursive Zoe

The Green TCP/IP Project

February 17th, 2005

While browsing around to find litterature for my paper proposal, I found this interesting website: The Green TCP/IP project.
For the ones that would not know TCP/IP is the communication protocol that the internet uses. This protocol is quite old and would be energy unnefficient.

“Studies by Lawrence Berkeley National Laboratory (LBNL) show that about 74 TWh/yr of electricity (which is approximately $6 billion per year) is consumed by the Internet in the USA alone, of which 24 TWh/yr or 32% could be saved with full use of power management on desktop computers, currently the most common of edge devices on the Internet. Unfortunately, due to limits of existing protocols and architectures, networked desktop computers typically remain powered-up during frequent and often lengthy periods of idleness. As network devices, they are prevented from operating in an energy-efficient manner due to their need to respond to network transactions of various types without warning.”

If you check out the literature section of the website you will see that there are interesting studies on the subject.

Reflecting on Java

February 17th, 2005

J-S’s proposal to research the social and environmental impacts of the Java architecture prompted me to see if there was anything on the social construction of Java, which led me to this. Enjoy.

Kyoto Protocol Enacted

February 16th, 2005

Today’s the day that the Kyoto Protocol comes into effect. If Canada fails to meet its targets in reducing greenhouse gases then it faces punishment (e.g., it will be unable to sell emissions credits). Of course, according to the article, Canada has already pushed back its industrial targets.

It has just been announced that Montreal will host the conference that is a follow-up to Kyoto in December. At this conference, some 10,000 attendees will hammer out the protocol that will supercede Kyoto when it expires in 2012. Maybe Canada actually have a concrete policy by then. And being in our city, maybe we can have an impact too. What do you think we should do?

The Sokal Affair

February 15th, 2005

An interesting thing I discovered while trying to gain some more background on relativism, was various accounts of the Sokal affair. The Sokal affair was something of a big deal in the Postmoderist world, wherein Alan Sokal, a physics professor at NYU, wrote a deliberately nonsensical paper in his own words, “a pastiche of left-wing cant, fawning references, grandiose quotations, and outright nonsense”, and submitted it to Social Text, a postmodern journal published by Duke.

The same day his article was published, he revealed in the journal Lingua Franca that in fact his article was meant as a parody. Of course, scandal ensued, with the story being picked up by many newspapers around the world, and various angry articles written about it.

In defense of Social Text, they are not a peer reviewed journal for the reason that they wished to promote more original research, and thus provide less of a guarantee about the accuracy of its articles. It doesn’t seem unreasonable that if someone like Chomsky were to write an incomprehensible treatise on nothing, many journals would be tempted to publish it simply on the weight of his name alone.

There are many sources of knowledge about the hoax, Sokal’s Website and Wikipedia provide a good overview.

Of course, I’m sure many of us have toyed with the idea of doing something similar, in both arts and sciences: whether to insert jargon in order to bewilder whoever happens to be marking it, that they will hopefully be fooled into believing the work is credible, or that they will be too baffled (and too proud to admit it) to comment on it. In high school, I played with this a little bit, where I would use two very uncommon words (correctly) in essays in close proximity, followed by a completely made up word that sounded ok. On one occaison, the first two words were underlined, however the third wasn’t, leading me to believe my teacher looked up the first two in the dictionary, and then seeing that they checked out, gave me the benefit of the doubt. Of course, Sokal took this a step further, by openly rubbing it in the faces of those who had bought his self described parody.

The hoax also serves to highlight the disconnect in academia which exists in many places between the arts and sciences. I can’t say I’ve ever really discussed social construction, relativism, or postmodern thought in university prior to this class (although I’ve only taken three arts classes) and I don’t imagine I’m alone. Likewise, I don’t imagine too many arts students have taken a lot of physics or mathematics courses. I suppose it’s a product of having undergraduate education becoming so focused, I feel like it’s not uncommon for people in the same field to be completely unaware of each others specializations.

Science, computer models and politics

February 14th, 2005

In politics all it requires is a little tweak of the computer model, perhaps a change in the units of analysis, and you get the result that the politicians want.

Subject: Survey: political intervention in science pervasive at USFWS

Hello everyone,
The Union of Concerned Scientists (UCS) held a press conference to announce the disturbing results of a survey of U.S. Fish and Wildlife Service field scientists: political intervention to alter scientific findings has become pervasive within the agency. At field offices around the country, USFWS scientists tell of being asked to change scientific information, remove scientific facts or come to conclusions that are not supported by the science. As a result, the scientists say, endangered and threatened wildlife are not being protected as intended by the Endangered Species Act.

Despite agency directives to scientists not to reply to the survey even on their own time nearly 30% of the scientists responded. You can find a summary of the survey, its methodology, and a summary of results broken down by region here or by clicking here.

RESULTS SUMMARY
The survey paints a vivid picture of the systemic abuse of science and the need for change. Results show that:

Large numbers of agency scientists reported political interference in scientific determinations. Nearly half of all respondents whose work is related to endangered species (44%) report that they have been directed for nonscientific reasons to refrain from making findings that protect species. One in five have been instructed to compromise their scientific integrity, reporting that they have been “directed to inappropriately exclude or alter technical information from a USFWS scientific document.” In the Southwest region, that number was even higher -closer to one in three.

Agency scientists reported being afraid to speak frankly about issues and felt constrained in their role as scientists. 42% said they could not publicly express “concerns about the biological needs of species and habitats without fear of retaliation,” while 30% were afraid to do so even within the agency. A third felt they are not allowed to do their jobs as scientists.

There has been a significant strain on staff morale. Half of all scientists reported that morale is poor to extremely poor; only 12% believed morale to be good or excellent. And 64% did not feel the agency is moving in the right direction.

Political intrusion has undermined the USFWS’s ability to fulfill its mission of protecting wildlife from extinction. Three out of four staff scientists felt that the USFWS is not “acting effectively to maintain or enhance species and their habitats.”

In one of numerous essays submitted on the topic of improving scientific integrity at USFWS, one biologist wrote: “We are not allowed to be honest and forthright…I have 20 years of federal service in this and this is the worst it has ever been.” Another scientist reported that Department of Interior officials “have forced upper-level managers to say things that are incorrect.” A manager wrote: “There is a culture of fear of retaliation in mid-management.”

Encouragingly, it is clear from the survey that USFWS scientists are committed to and proud of their work and believe in the potential of the agency to conserve, protect and enhance fish, wildlife and plants and their habitats. However, political intervention is having a chilling effect on the ability of USFWS scientists to carry out the agency’s mission.

UCS has joined with Public Employees for Environmental Responsibility (PEER) to design and conduct surveys of several government agencies to document the abuse of science and determine the pervasiveness off the problem. The surveys will assist the scientific community in documenting that the abuse of science is an ongoing, serious concern. We are looking into ways that the results of the USFWS survey can be used to further a more thorough investigation of this problem.

It has taken decades to build worldclass scientific staff at the USFWS and other government science agencies. The future ability of the agency to fulfill its mission will be severely hampered if this political interference is allowed to continue. To restore scientific integrity at the USFWS, at least two reforms are needed: there must be protections for scientists who are asked to take actions that violate their scientific integrity and the Bush administration must recognize at its highest levels that manipulating or suppressing science for political reasons is unethical.
