Someone keeps stealing my letters…

Wednesday, 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

Tuesday, 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

Tuesday, 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

Tuesday, 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!

SHA-1 kracked!

Monday, 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

Monday, 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

Sunday, 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

Sunday, 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.

Podcasting the environment

Sunday, February 20th, 2005

There’s lots been written on the value of the Internet for environmental activism, such as listserves, webpages, blogs, wikis, etc.

Could podcasting be the new wave of environmental activism on the web? Check out Tired of TiVo? Beyond Blogs? Podcasts Are Here

The Green TCP/IP Project

Thursday, 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.

The Sokal Affair

Tuesday, 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.

Do computers “feel” strain?

Saturday, February 12th, 2005

I am in the middle of scanning a few maps for my ecological restoration class. I put down a map presenting the number of thunderstoms…. in the United States and pressed scan…

Next thing I knew, I caught myself FEELING BAD for the computer! I felt sorry for having to put the computer through such great strain, by asking it to import an image via a scanner. Why did I have this feeling? Becuase the scanner window in photoshop was shaking as the lamp was moving inside the scanner. Or, at least to me it was shaking – same as a person would shake in fear, anxiety or shock. I guess what was really happening is that the window was flashing – light, dark, light, dark… I’m not sure why this is, but I’m sure it has a very logical and precise explanation.

Do we personify computers like we personify Sally the cat or George the dog? Are they any people that name their computers? I can’t count the number of times I’ve heard family members or friends say, “give the computer a rest”. I wonder if couples argue overthe decision of whether to get a pet or computer to add to their homes.

I certainly won’t grieve over the “death” of my computer when its time comes – i will be happy to replace it with a better one… I don’t know if all you cat lovers would feel the same way about your cats, and we certainly wouldn’t feel that way about a family member.

My vote is to for computers as material objects that have no emotional significance in our lives.

Technology and Religion

Wednesday, February 9th, 2005

Our origin is a great mystery, but it may not be so mysterious soon. Research into the “God Particle” in Geneva is being undertaken, to try and recreate the same conditions that resulted just after the big bang. It is known that the creation of the world with all the steps involved, all the chemical processes and exact sequence of events, was a very rare thing to have occured. In fact the odds were against us, so it seems that there must have been someone or something behind the engineering of this sequence of events. There must be some purpose that we are here. The fact that humans have been given the capacity to produce endless amounts of bits of information, reveals that we are intelligent agents, but for what purpose? I do not know. In the human body, our DNA is made up of proteins, which are engineers in themselves, very complex machines, really. But now that we know how they work, we can change our evolution patterns. We have become engineers of life itself, and this is not something we had real direct control over hundreds or thousands of years ago, this is a new emerging science. So where do we draw the line? And now that we have cracked these DNA codes, we are trying to reverse engineer the process to find answers…is this what our engineer would have wanted? It seems that technology has become the new religion, as we put so much faith in it…

Is Climate Change Awareness an Innovation?

Monday, February 7th, 2005

After our class discussion about ignorance of people about climate change and passionate wake up call from Jennifer in the Blog :), I wanted to bring up an interesting analogy that I think there is between convincing the village people that boiling their water is good in the article “Diffusion of Innovation” vs convincing people (mostly westerners) that something is going wrong with earth and that stopping polluting is good.

Just has boiling water didn’t go well with the village beliefs, stopping polluting/consuming doesn’t seem to go well with western beliefs/habits of consumption/capitalism/etc… The reality is that we are brainwashed 24/7 that we have to buy more and more stuff… disposable goods, fashion, marketing & more marketing all good incitatives to make us consume more & more (this is just a few examples).

We can continue the analogy with the scientist trying to convince the people of the village by explaining them
the scientific reasons to boil the water vs the environmentalists trying to explain the scientific reasons to stop polluting. A very little percentage of the population actually understand anything of it. It comes in one hear and goes out from the other; or it is rapidly forgotten under… just everything else. Furthermore the environmentalists themselves are marginalised… although it is less and less true they are still seen by a lot of people as tree huggers, hippies and dreamers… whatever.. the point is that most people don’t relate to them, just as nobody in the village relate to the westener scientist.

So my conclusion is that climate change awareness (and environment-friendly habits) is an Innovation that currently (and unfortunately) goes against western values. As westeners have been conquering the world and propagating their values all over the globe during the last centuries… I think that we are in big troubles. It’s going to take much more than regulations, sensibilization or a Tsunami to change the way people think.

There is already a few early adopters, but how are we going to manage to diffuse that innovation to the rest of the people? This is a hard problem and maybe quite critical, but we could (& should) probably inspire ourselves and learn from the diffusion of other innovations.

pins 1, 2, 3 and 6

Sunday, February 6th, 2005

Here is another obscure item but I think you’ll like it…

In practically every modern office building and indeed in many homes, you will find hundreds if not thousands of metres of network cabling. I’m referring to the cables, slightly thicker than telephone wires, that run through walls and ceilings, are stapled under carpets, and connect computers, printers and servers to hubs, switches, and routers. They are almost always blue although sometimes the shorter ones are grey. Look around McGill and you’ll spot them; the ceiling in the basement of Burnside is a good place to look.

These days most network cabling is ushielded twisted pair (UTP) – inside that blue or grey outer sheath are a series of small copper wires twisted together, each one wrapped in its own insulation. Well before the advent of computer networking, voice communication was already requiring huge quantities of UTP cable but the modern local area network (LAN) increased the demand for this kind of cabling exponentially. It would be difficult, maybe even impossible, to estimate the amount of UTP cabling in use today. Increasingly, organizations are switching to fibre optic cables for longer distances; these cables carry thousands of times more data than their copper counterparts. And the migration to voice-over-IP technology that essentially combines voice and data on one cable is also reducing the use of UTP cabling. But the resource use by cabling of all types cannot be ignored.

Imagine all the plastic and copper needed for all that cabling and imagine what will happen to it all when eventually fibre replaces all of it. But this post is not about the basic environmental consequences of network cabling, there’s a more interesting tidbit to share…

Those blue network cables are 4-pair, which means there are 4 pairs of wire, 8 conductors total, inside each cable. At the end of the cables are RJ-45 connectors, they sort of look like oversized phone connectors. But here’s something that most people don’t know: only half of the conductors in a 4-pair UTP cable are needed. Ethernet networks, even gigabit ethernet, only use 4 wires. According to official Ethernet cabling specifications, the other 4 wires are reserved for “future use.” Now imagine all that cabling all over the world, half of all the wires inside those cables are unused, completely wasted. You could create a perfectly functioning network cable with 2 pairs instead of 4. In fact, many of the cheaper cables you find at FutureShop or RadioShack are made this way.

Why did this happen, you might be thinking. Why would they come up with a standard that only uses half the capacity of the cable? Could it go faster if they used all the wires? All good questions and maybe ones I will answer in my paper…

Can’t get away from the real world in online games

Sunday, February 6th, 2005

From MSNBC, via Slashdot, what’s going on in massive multiplayer games boggles the mind.

A funny thing is happening in these sprawling online multiplayer arenas. The ultimate in digital escapism, virtual worlds keep ending up in the ultimate in depressing reality: the courts.

It goes onto to explain how players and game companies are engaging in legal battles over virtual activity. However, this is the quote that got me to sit up:

Digital sweatshops, businesses where [real]Third World laborers play online games 24/7 in order to create virtual goods that can be sold for cash, are also on the rise.

Apparently players can buy digital goods on sites like eBay as a way to enhance their playing experience. One such sweatshop produces digital weaponry that is then auctioned off for real money. To give you a sense of the kind of money we’re talking about, a digital island on eBay recently was auctioned for $30,000. That’s $30,000US in real money to buy a virtual piece of property.

For more information on virtual worlds and the law, check out the conference, State of Play.

To bring it back to the topic of the blog, I wonder if there is any environmental regulation in these digital worlds? Can we have a clean air act in EverQuest?

Edible Packaging

Thursday, February 3rd, 2005

We know that packaging makes up a large portion of the waste stream today. A paper published by the American Society of Agricultural Engineers highlights a new type of edible packaging designed by the Agricultural Research Service together with the Western Regional Research Center. The edible packaging is made of food and vegetables, that can be used to store food and also can be eaten, and in themselves, contain nutritional benefits! It could not be used alone, though, in places with unsanitary conditions nor could it be used during transport and storage; however, it would ideally be used for packaging leftovers in the refrigerator, or food carried in a lunch bag. Considering 1.8 million tons of packaging waste is dumped into landfills each year, this may reduce some of the waste. Moreover, they were experimenting with different ingredients to make the film that would be the protective coating. They used apple puree, and various lipid-based concentrations.

A few years ago, during high school, I did a co-op program at the University of Western, and worked in a chemical laboratory, harvesting bacteria to make cellulose. Cellulose was originally found in fruits, (in Japan, it was first commericially harvested from a rotten black cherry), but today it is used in a variety of ways and across many sectors. Its strong and resilient, yet flexible properties makes it versatile, lending itself to products such as medical tools, wound dressings, personal hygiene products, and also it is used in low-fat drinks (it doesn’t have any calories, but it makes the drink thicker). I’m curious whether they’ve considered this type of technology for their use in edible packaging. They probably have…

What will it take?

Thursday, February 3rd, 2005

Ok… well here we go, my first chance to steer away from the technological aspects of this course… although I don’t know how any blog can not be related to technology, due merely to the fact that a blog requires a fairly advanced combination of technology. This post relates to the intersection of nature and society.

So in searching for a blog to review I found a list of blogs related to the December ’05 tsunami, a natural (or was it?) disaster, occurring in South East Asia. I came across one blog that was a honey-mooning couples account of the seismological activity and resultant environmental and cultural effects. If you have the time to skim through this blog please pay special attention to the recurring theme: what happened to the couple’s luggage.

The point I want to make here, is that planet Earth just experienced one of the largest natural disasters in recent history, yet many of the human inhabitants of the Earth can not get past the idea that the tsunami may affect their cultural lives. The honey-mooning couple was worried about their luggage, locals are worried about rebuilding their homes, caring individuals are thinking about and helping the many orphaned children, but who is thinking about the state of the Earth?

With global climate change upon us, scientists are predicting that natural disasters will only happen more frequently and more intensely, drastically altering the Earth as we know it. What is the sake of culture if there is no place to host it?

What people all around the world need to start realizing is that these “natural disasters” may not be so natural at all… that is if you consider humans to be removed from nature. Human induced climate change is a real possibility – it may be that our own species is taking enjoyment (i.e. driving around their fancy cars, consuming factory made goods) from creating conditions that may prove only to deteriorate the cultural world as we know it. Hundreds, even thousands, of communities were demolished as a result of December’s tsunami – why wasn’t it yours or mine? What will it take for people to realize that we are our own demise?

No amount of warning signals (eg. Tsunami) or awareness attempts (eg. “The Day After Tomorrow”) seem to be working: I still see countless cars everyday carrying only one person and there is no shortage of goods requiring huge factory emissions for production. Societal stubbornness wins out again.

Wake up people!

Keyhole

Thursday, February 3rd, 2005

Well, I basically just wasted my entire night playing with this program. If you have a Windows computer I really recommend playing with it for the week trial, all it asks for is your e-mail, and Google recently bought them, so hopefully they’re not too evil.

The program (Keyhole) is basically a big clickable zoomable map of the entire world, which streams information from the internet (so it loads as you go) about whatever you happen to be looking at, including borders, cities, and street names, altitude, latitude and longitude. For quite a few north american, and a few famous ones in the rest of the world, you can actually zoom in far enough to see individual people and cars! It’s extremely cool. Besides trying to find your house (which my roommates could), other fun things to zoom in and/or try to find: the Coliseum in Rome, Tiananmen Square in Beijing, the Statue of Liberty, the Eiffel Tower, and probably a lot more.

Anyways, it really is very cool, and if you happen to have a semi-decent windows computer, you should certainly check it out here.

Slashdot Review on the Cellphone Blog

Wednesday, February 2nd, 2005

The blog posted by “timothy” is fairly short, but brings up an interesting article regarding a study that was conducted at the University of Utah in which cell phone users have impaired driving skills. This link was also included in the blog and leads to the news article. I notice that whenever I walk on the sidewalk and someone is talking on their cell phone and approaching me, they always run into me, even if I stop and like go in the opposite direction…it bugs me. It’s funny though. Whereas, in the past we would see people talking to themselves on the street and think they were crazy, now we see people talking to themselves (with a hidden phone), and assume they’re fine.

The act of blogging leads me to a question, regarding intellectual property. If a person chooses to blog, and his or her ideas are made open to the public, can they claim it was their intellectual property, if someone else chooses to use his or her idea? And if so, are there any consequences for the person who uses their material in some way? How would one even monitor this…?
