Going Mobile: Network Neutrality
The traditional approach for implementing solutions in wireless sensor networks is to use academically designed sensor motes, which provide an open hardware and software platform. Such devices have been good for addressing fundamental problems, like radio irregularity, routing, data aggregation, and power savings, all of which require fine-grained control (open source) over the software and hardware. While sensor motes provide a good proof of concept solution to some problems, more practical solutions are needed that are more attention-grabbing than a collection of weak, low power devices with limited sensing capabilities. Basically, there aren’t a whole lot of applications for sensor motes that would be useful to most people. A more recent approach is to use cell phones, which are increasingly becoming equipped with GPS, accelerometers, and microphones, providing a platform for interesting and practical wireless sensor solutions. However, the hardware and software of most cell phones are extremely restrictive, clamped down by manufacturers and wireless providers, effectively limiting the research possibilities. For example, one can’t just perform a clear channel assessment using a cell phone’s WiFi radio without less restrictive or open source drivers (even with Android). Such restrictiveness is hindering improvements in mobile devices and many of these improvements would be welcomed by everyday consumers.
Like landline phones, Internet users will eventually drop wired ISP connections in favor of wireless. This shift towards mobile and ubiquitous computing emphasizes that wireless infrastructure and usage policies will be critical in the coming years. With few exceptions, ISPs have followed the principles of network neutrality with respect to wired networks, permitting wired customers to use any device with any software using any communication protocol. However, such openness is not reflected in wireless networks with ISPs placing heavy restrictions on devices, software, and means of communication. To ensure competitive pricing, hardware innovations, exciting software applications, and available bandwidth for the surge in wireless traffic, wireless providers must follow the principles of network neutrality. Since wireless providers are hesitant do do so, the FCC’s decision to enforce network neutrality is a step in the right direction. The enforcement of the FCC’s network neutrality principles will allow researchers to push mobile computing to new and exciting levels and will allow consumers to get more functionality at lower prices.
The openness of the wired Internet has seldom been encroached upon by ISPs and rarely regulated by government, making the Internet the world that it is today. This freedom has been defined by the FCC’s four principles of network neutrality:
- A user can access any content over the network. All who access the Internet are provided access to everything on the Internet, whether it be an AP news report or the Unabomber Manifesto. No ISP restricts content: everything is available, even if it may be morally objectionable or illegal.
- A user can run any application or use any service over the network. Anyone can use any web service or application (Google, Mapquest, Facebook) without restriction from an ISP. No ISP prevents users from making Skype calls even if that ISP also sells landline telephone service.
- A user can connect any device to the network, given it does no harm. An Internet user can connect with any hardware, whether it be with a ten year old piece of junk running Linux or with a $10,000 top-of-the-line quad core processor running the latest Windows 7 beta. No ISP restricts a user’s Internet access because his or her computer is a piece of junk. Nor do ISPs force users to connect only with proprietary computers sold by the ISP.
- Competition among network, content, and application providers. A user is open to choose from one of several ISPs (if more than one are even available), and also has choice over competing web services and content providers.
This freedom has not always been maintained, even with the wired Internet. Two years ago, Comcast deliberately throttled the bandwidth of peer-to-peer protocols, limiting the upload and download speed of file sharing applications. With peer-to-peer using customers enraged over this finding, the FCC forced Comcast to abandon this policy. Other than this incident and a few others, the Internet has always been delivered equally to all who have access.
Unfortunately, such open policies of the wired Internet are not followed by wireless providers. From the very birth of cell phones, wireless providers have controlled everything:
- Unrestricted content. Wireless providers block (through restricted software) bandwidth-heavy content, such as streaming videos, voice/video communication, as well as file sharing. Such restrictions are in place to limit or prevent wireless network congestion. Improvements in wireless infrastructure could alleviate such congestion, but wireless providers have decided to restrict, rather than improve.
- Use of any application or service. Nearly all providers restrict the operating system and applications available on connecting mobile devices. Apple blocks the use of Skype when the phone is not connected to a WiFi network. Similarly, the Google Voice application was also removed by Apple and AT&T. Both applications provide features that could be seen as subversive to standard cellular voice calls. Instead of providing competing applications (maybe with better features), the ISP and application providers just block any competition.
- Connection of any device. Verizon’s network may be good, but their phones are terrible. A customer cannot just build their own tricked out phone and connect it to Verizon’s network. Instead, users are forced to choose from a handful of phones with menial features (only sold by Verizon, of course).
- Competition. Since content, applications, and hardware are restricted on most wireless networks, competition is limited. Only a handful of wireless providers offer large coverage areas, especially for data communication. Since the United States pays more for wireless than any other western country, it is clear that less restriction would provide more options and more competition for consumers.
Despite the crackdown on allowable hardware, software, and access, wireless executives somehow manage to argue that their industry is “perhaps the most competitive consumer market in America.” While unregulated competition would be great for consumers in terms of increasing wireless freedom, there simply isn’t enough competition to go around. There are only four major carriers in the United States, effectively forming a cartel that can set prices artificially high and extensively limit consumer freedom. With barriers to entry so high (infrastructure), few new carriers are likely to emerge. In cases like these, government intervention is the only solution. Fortunately, the FCC is investigating the lack of competition in the wireless market with respect to insane billing rules and lack of consumer freedom in comparison to the wired Internet. Of course, their latest decision to enforce network neutrality will also provide a strong push.
The end result should allow anyone to build their own phone, install a custom operating system, and connect it to the wireless provider of their choice without issue. Such a user should be allowed unrestricted access to the entire Internet without throttling or restriction of streaming video, large file downloads, or VoIP calls. Ultimately, text messaging and voice calls will be merged into wireless data plans, removing such unreal and confusing costs like $.25 to send a 160 byte message or “anytime” minutes, which are anything but anytime. Unrestricted hardware, software, and access will bring increased competition among existing wireless providers, fostering the development of better mobile hardware and cool applications.
Force Fed by Broadcast Media
If I see one more thing about Michael Jackson I’m going to puke.
As I was heading home from Rome, a guy in the seat in front of me had a USA Today with a full page spread and giant picture of Michael Jackson. I couldn’t read the text, but it was pretty obvious that he had died. Ever since I got home, every newspaper front page and every TV news station has been droning endlessly about Michael Jackson and rehashing every last detail pertaining to his death.
I don’t care and I don’t want to hear about it. It doesn’t interest me.
If I were biking somewhere outside of Williamsburg and crashed into a ditch and died where nobody could immediately see me, it could be a week before people even noticed I was missing. It might be up to two weeks before someone would think to file a police report and even longer before anyone would find my body. Few would care that I was missing or died, and such is the case for the thousands of people that die every day. None of them get news of their death plastered all over newspapers and television for days on end, and most of the world really wouldn’t care to hear about it.
The problem with this is that this is difficult to get away from when relying on broadcast media alone. Turn on the TV and it’s Michael Jackson. Turn on AM talk radio and it’s Michael Jackson. Open to the front page of the newspaper and it’s Michael Jackson. The good thing is that with the power of the Internet, and social networking, it’s easier to find alternative sources that give you the news you are interested in. The Internet is the great equalizer in that you no longer have to mindlessly read, watch, or hear what media executives want you to see. You can read about the topics you are interested in from a wide range of sources.
Those in broadcast media don’t like this paradigm shift. They file suits complaining of copyright infringement, claiming that they are losing money due to DVRs and piracy. The real issue isn’t as much monetary as it is control: broadcast media wants you to watch only what they feed you and only at the time they want you to see it.
Since broadcast media isn’t willing to embrace the Internet, they even try to restrict the freedom it brings in ways much more backhanded than traditional lawsuits. Recently, the New York Times worked with Wikipedia founder Jimmy Wales to stifle edits about a Times journalist being captured in Afghanistan. While hiding the news about the capture was meant to save the journalist’s life, if it were anything but a journalist that was captured, news of the capture would be blasted all around the world by the same news outlets trying to keep this case quiet. It’s as if those in the media industry think they are on a plane above everyone else. They want to think our thoughts for us and only show us what they want us to see. Most people just blindly follow along as evidenced by comments in blogs and Facebook. It’s time to stop being sheep.
I find myself watching almost no TV and reading the newspaper less and less, skipping through most of the stories and only reading the things I’m interested in. Personalized Google News and Digg do a halfway decent job of filtering out broadcast media’s force feeding. Maybe soon everyone will realize that plenty of other things happened today than the decision of who is receiving custody of Michael Jackson’s kids.
The Coast Guard and location prediction using Monte Carlo simulation
In the paper this morning, the front page article was on debris tracking and prediction for Air France Flight 447. Software developed by the Coast Guard in Portsmouth is being used in the recovery effort to predict where debris is located. Ocean currents are used along with the last known location of the plane to predict the most likely places where debris will be found. A density map of location probabilities is shown in the article and I knew without reading it they were using Monte Carlo simulation. This was confirmed in the article.
Using water current and Monte Carlo simulation to predict object positions in water? This sounds really similar to our Sidewinder paper. It’s strange enough that the people who did this debris location prediction practically live right down the block.
There are plenty of differences, though. I would bet that the Coast Guard’s current model is much more advanced than a general group velocity with random deviations for all objects involved. Instead of predicting debris location, we use Sequential Monte Carlo simulation to predict the location of a sink node in a mobile wireless sensor network. The prediction is refined over multiple hops to make routing more reliable and efficient in a highly mobile environment, such as floating sensors routing data in a flood tracking application. A similar density plot to the one provided in the paper is created at each hop for the estimated sink location. This density plot becomes darker and smaller with each hop as the refinement occurs. I’m guessing that the Coast Guard doesn’t use such sequential refinement.
So where’s my front page newspaper article on SMC prediction and flood tracking?
The mediocre call it obsession
But I call it passion.
Today, there was an article in the local paper about a guy, Paul Boyette, from Chesapeake who had a running streak that lasted over six years. He ran at least two miles every day, running through injuries, terrible respiratory infections, and all kinds of weather. His streak was finally ended by a torn meniscus which proved too painful for him to run through. Oddly, this happened last summer, within a month of the pain in my knee becoming too great to run. The article was really vague as to what happened after he stopped because of the torn meniscus, but one of the photo captions describes him running last month. So, it appears as though he is back to doing what he loves.
The author of the article really makes this guy out to be an eccentric, hounding him because of his massive music and beer stein collections. The author describes how Boyette’s family and friends gave him endless grief about maintaining the running streak and running every day though illness and injury. Boyette is compared with a drug addict, as someone who has to get his fix or else he can’t function. His stacks of meticulously kept running logs and piles of worn out shoes are referenced as paraphernalia, aiding the addiction. A few commenters for the article say the guy is addicted to endorphins.
It isn’t addiction. It isn’t obsession. It is passion. Over the years, I’ve been hounded by people saying the same things, over and over:
“Why are you running in this weather? It’s too [cold/hot/rainy].”
“If you’re tired, take a day off.”
“Why don’t you try doing something else instead of running?”
The mediocre, the average, the run-of-the-mill Joe Six Pack only cares enough to go through the motions with any activity. These people, which make up a large majority of the population, see those who put all their effort into something as obsessive. The mediocre only wish to do good enough and to quit early. They will never feel good about any of their accomplishments, yet they simultaneously envy and criticize those who work extremely hard and become successful. The mediocre are everywhere and would love nothing more than to witness the failure of those who actually try. To that end, the mediocre spread their negativity and criticism to those they know that are successful, secretly wishing their endeavors will implode and their work will be for nothing. The author of the article and the commenters that follow are prime examples of those who just don’t get it.
People scoff at Bill Gates for sleeping in his office during the early years of Microsoft, working at his computer until he collapsed onto the floor with exhaustion. Though the mediocre label him as obsessive and wish to see Microsoft wiped from the earth, every single one of them has used a Microsoft product. If it weren’t for Gates’s efforts, this large scale success would never have been realized. Computing would never be what it is today without those “obsessives” working until they drop on the floor. Still more people can’t believe that the efforts Adam Savage of Mythbusters undertook to recreate an exact duplicate of the Maltese Falcon. He spent months of work researching the prop from the film, drawing sketches, making several mockups, and eventually getting his hands on the original prop to create a near flawless duplicate. In the video, Savage’s passion for his work really comes out as he speaks quickly and excitedly about every last detail of his quest. You don’t see that with the mediocre. You can tell when someone is passionate about their work when they speak of it like Savage, and you can tell when someone really just doesn’t care. I’ve seen professors, other grad students, running teammates, and internship co-workers speak with the same excitedness as Savage when they speak about their latest accomplishments. The passionate can pull you right into the hype.
It disappoints me to see that most others criticize the concentrated efforts of those like Bill Gates and Adam Savage while it is efforts such as those that keep the world in one piece. Without them, this world would be a bunch of slackers.
So why run until the pain becomes unbearable? Why work until you fall asleep at your desk? It is because not doing so would be a failure. I ran every day I could because I wanted to make the best of what I had. I ran every day and through all weather and many illnesses and injuries of my own because I knew there would be a day where the problems would be too great to run. On that day when I finally couldn’t run, I could look back and know that I had done my best. On the day I couldn’t run, I would have no regrets about the past. I would not have to wish that I had gone out for a run on a day that I was only too lazy to go. That day came last summer when my knee made running unbearable. Like Boyette, I had to stop. I had no regrets: I knew that I had made the best with what I had. Those who are mediocre will regret the day that they are unable to do something because of circumstances beyond their control. They had the chance to give it their all, but they didn’t make use of it.
I hope that I never again get criticised for biking or running as much as I can or for doing work when someone wants me to go out. It is what makes me who I am and it is not a disorder that should be treated with magic pills.
One reason grad school is different
My sister (and others) have been complaining about the gobs of work they’ve got to get done during exam period. There are papers, projects, and of course, exams. My case is somewhat different. I remember how it seemed all kinds of massive projects and papers were due right before or during exams, and then I would have to suffer through a whole ton of exams. It was a huge weight off my back when it was done.
But now, it’s almost worse. I started working on my current project in September, right after my knee surgery. It’s been going for nine months and now I am finally cramming all of those nine months into ten pages or less, double column.
To put this in perspective for an undergrad: take all the papers, all the projects, all the homework assignments, and all the exams, tests, and quizzes in the last two semesters and make them all due next week. That is the weight of what I am working on. It nags at me every day that I have been working for so long and have nothing to show for it. I think about it in bed before I go to sleep, I think about it when I wake up, I think about it when I’m in the shower, and I think about it when I’m on the bike. As an undergrad and even for the first part of grad school, I got closure incrementally: with periodic assignments and tests and at the finish of each semester when classes end. Closure is now when I get a paper out, and the time span for that seems indefinite.
My first project and paper was faster — it took a semester and a summer. However, I’m still dealing with that project now — I’m going to present it at SECON and when I do, it will almost be a year since the first version of the paper went out.
It seems most undergrads treat papers lightly: “Oh, I can crank out a ten page paper in a few hours and still get an A…” I was the same way — it was spit something out as fast as possible to get it over with, but put enough effort into it to get a decent grade. Now, papers are everything. The paper is how everyone else sees your work. I may have spent the past nine months creating something that could have huge implications for the future of wireless sensor networks, but nobody but my adviser would know about it unless I tell them in a paper. The reviewers will lay the smack down on you if you try to whip out a paper in a matter of hours. Yesterday, I spent six hours writing and got out about five paragraphs. They were five critical paragraphs about the core of what I did, and they had better be comprehensive and understandable from the perspective of an outsider.
I find it hard to tell the story of my project, but I think the difficulty is from inexperience. There are key things that reviewers look for that I must give special attention in addressing. Because of this, there is a pretty rigid way to write a research paper, but even then I find it difficult. It is hard to convey specific algorithmic details, yet be concise and easy to understand. I have to remember the main selling points of my work and refer back to them throughout the paper. For these projects, I find the initial problem discovery, solution design, and implementation to be interesting and sometimes even fun. Enough experience programming and thinking about solutions to problems has helped with that, but I haven’t done much writing.
With time, I imagine writing will get easier. I will know exactly what to do. With my current paper, I’m almost there. I’m almost to the point where I feel good about what I have written and know that everything will turn out okay. I just have to keep working and get it done. Then there will be some closure.
Ubuntu 9.04: Rough Upgrade
I recently upgraded from 8.10 to 9.04 on my desktop machine, and so far, it’s been a mess. This was not the painless upgrade from 7.10 to 8.04 or from 8.04 to 8.10. So far:
1. ATI/AMD is no longer providing drivers for my X1900XTX video card, so I’m using the free drivers. The problem is that I can’t use two monitors without the mouse flickering like crazy and some strange window focusing problem where an unfocused window “jumps out” at me occasionally and then reverts to normal. Disabling compiz and visual effects didn’t solve this. Only when I disable the second monitor do the flickering and focusing issues go away. I’m still messing with this one to try and find a solution, but there isn’t anyone else on the internet that’s complained about this. I find it funny that people switch to Linux so they can run older hardware, but without driver support, that can’t happen. The free drivers work well, but only if you’ve got one monitor.
2. Something hosed my ability to play MP3s with Amarok. From this thread, I learned that running the following solved the problem:
sudo apt-get install phonon-backend-xine
3. Flash stopped working in Firefox. Any page with Flash would crash Firefox. This can be solved by uninstalling and reinstalling Flash:
sudo aptitude remove flashplugin-nonfree flashplugin-installer
sudo apt-get install flashplugin-nonfree
4. My Eclipse installation randomly crashes. Also, the splash screen never goes away after starting up. I’m in the process of reinstalling Eclipse to see if this does anything. Edit: reinstalling appears to have fixed the crashing and splash screen issues.
This hasn’t been an enjoyable experience so far — I was under the opinion that Linux is reaching maturity, especially Ubuntu, but this is definitely not the case. The problems I’m experiencing seem to be a step backward from the last upgrade cycle. As I just mentioned, the ability to run fast on older hardware is a huge enticement to switch to Linux, and if my three year old desktop can’t handle it, there’s a lot more work to be done. I’m certainly not going to buy a new video card that’s worth much more than the rest of the computer.
Published
My past year and a half of research-oriented work has resulted in a conference acceptance. This summer, I’ll go to IEEE SECON in Italy to give a presentation on:
Sidewinder: A Predictive Data Forwarding Protocol for Mobile Wireless Sensor Networks
In the coming weeks, I’ll have to revise the paper somewhat for publication and then prepare a presentation. As a M.S. student, a lot of my classes involved reading papers and giving class presentations on them. I hadn’t thought much about it at the time, but it really sets everything up for the next phase: presenting your own research. It will be interesting (and challenging) to face down some tough questions on my paper from people all over the world.
In the meantime there’s a whole bunch of other work I’ve got to take care of on a current project. Things are about to get interesting.
This weekend I…
Posted by Matt in general, microfracture on April 5, 2009
… rode outside for the first time since the surgery. This was a huge step forward and I had been waiting too long.
Over the past week or two I had been getting really restless. The hour on the trainer every day gave me a workout, but the weather was starting to turn. Spending nearly 95% of my time indoors over the past seven months was starting to really get to me. As goes the quote from “Office Space,” “Human beings were not meant to sit in little cubicles staring at computer screens all day,” which was pretty much what I have been doing. I would walk back and forth from the Computer Science office and that was about it in terms of getting outside. Something was about to give.
It gave this weekend. The Colonial Relays was this weekend, and on Friday I walked over from the office and watched some of the distance races. The hour or so that I was out there had been the longest I’d been outside in quite a long time. That night, I went back and talked to a few of my teammates and alumni that had come back to watch. It was a great change of pace and was good to see everyone run. I talked to a lot of people that I hadn’t talked to in months, some even longer than that. A lot of people asked me when I would try running again, since the doctors have given me the okay to start. I replied that I wasn’t sure, but it would be soon. In talking to my old teammates, I had forgotten what I had left behind. For quite awhile, I’ve been in my own really tiny world, working on my projects.
Until now, the only times I would be shocked back into reality was when I would be having a discussion with my adviser in the late afternoon. We would be having a discussion on the whiteboard in his office and I would happen to glance out the window and see all my teammates run by in a blur. It’s a real kick in the butt to see that and remember what I used to do. In the world of computer science, the atmosphere is mellow, but determined. In the world that I came from, it’s about getting on the track and suffering. Unfortunately, in the context in which I live now, I don’t think anyone says, “I really dominated in that conference paper.” You don’t sweat and breathe hard while thinking up and coding a slick algorithm.
On Saturday, I got up, ate breakfast and prepared to do what I had done since before Thanksgiving: get on the trainer and pound away for about an hour. I would open the window, turn on the fan, and listen to music while I looked outside at the law students coming and going from the library. But on Saturday, the sun was shining and it was getting warm. I couldn’t take it any longer: it was time to go out.
It was about the best feeling I’ve ever had. I was uncaged, released into the wild, my natural habitat. I hauled it out past the state park at York River. The weather said the wind was blowing 30 mph gusts from the west, but I didn’t notice a thing. I powered up hills where over the summer I remember being exhausted and downshifting into the lowest gear. I remember trying to upshift, only to look down and see there were no more gears to use. A dog bolted out from its house and chased after me for nearly a quarter mile, but I kept it at bay. I turned around right before the road ended at the river. As I got closer to home, I never got tired. I looped around campus and got to the track just in time to watch the 4×800.
Yesterday was the first day in months that I didn’t do any work before dinner. I still did a little before I went to bed, so I couldn’t call it a complete day off. I was outside at the meet all day and got a nasty sunburn. I guess that happens when you don’t have a built up tolerance from running or biking outside every day. I watched all the distance relays and hung out with everyone some more. By the end of the day, I was exhausted. On the bike, I’d gone 45 minutes over an hour, and despite feeling much easier than the trainer, was enough to make me not want to move for most of the afternoon.
Today I went out again, but took it easier. I was definitely more tired today and felt more normal as compared with pre-surgery rides.
As for my knee, I was out of the saddle several times and really hammered up some hills without any real discomfort. I might have felt something this afternoon walking around, but I can’t be sure. I do know, that if my knee could handle what I did today and yesterday, I’m pretty sure I’ll be able to do at least some running. Sometime soon, the same thing will happen with biking outdoors and I’ll just start running on a whim. It won’t take much to push me over the edge.
I finally broke down and got a new bike. For awhile, I’ve been worried that the rear cogs are so worn that someday I’ll go up a hill and the chain will just rip off. I tried a few new bikes out at the bike shop, the first one being a Specialized aluminum frame. It felt like my old one, nothing really special about it. But, I tried a Giant TCR-0 with a carbon frame and it felt like a rocket. It was an unused 2006 and I think I got a pretty good deal on it since equivalent new models of just about every manufacturer go for about $1000 more. I’d been to bike shops quite a bit in the past few years and I don’t often see anything older or discounted. It seems most owners keep a limited stock. The components had been switched up and have a combination of Shimano Ultegra and 105. I really don’t need the way high end components since I don’t care too much about saving some fraction of an ounce of weight. As it is, the bike feels like a feather compared to the steel Bianchi. Since my shoes and pedals were a mess, I went ahead and replaced those. Hopefully I’ll be able to try out the bike before the weather crashes this week.
If I can bike or even run outside more often it will provide more of a balance to my life. I really can’t just hole up and work all day — there’s got to be a balance to the equation. The recent discussion about goofing off boosting productivity probably has some merit in it. Biking or running isn’t really goofing off, but it provides the same release.
Who pays for the Internet?
This was the question presented by the professor of my undergraduate networking class. As far as I can tell, the answer is: you do. And you’ll pay increasingly more for it if some people have their way.
Unless you live in an area with subsidized broadband and/or wifi, you’ve got to pay an access fee to an ISP. At this point, dial-up is more or less useless, so you’ve got to fork over $40 every month just to get online. Like most people, your ISP is probably a large telecom, like Verizon, Comcast, or AT&T, so the true cost is probably a lot more than that since it’s almost impossible to buy internet access by itself. You’re forced into signing up for a “bundle” which is some combination of land line phone, cell phone, TV, and internet all provided by the same company. A lot of the junk (and added cost) that comes along with the bundle is probably unwanted, like bizarre foreign language TV channels, call waiting, and hardware rental fees since the option isn’t often given to buy your own modem or cable boxes. By purchasing a bundle from an ISP, you’re subsidizing the weirdos who actually watch some of those high-numbered TV stations, listen music on their TV, or enjoy being nagged by call waiting that can’t be turned off. Since the number of providers available for a given location are usually pretty limited, you’re forced into paying monopolistic prices as well as paying for services that you don’t even want.
It’s bad enough that you’ve got to fork over the dough for services that you don’t even want in order to get internet access, but in truth, it’s a lot worse. Access is merely a base cost for using the internet. In nearly all cases, there’s also a cost for accessing content. Somebody has to pay for hosting and generation of that website you frequent or the videos you watch, and again, it’s going to be you. Advertising is one commonly used method to shift the cost onto consumers. Nearly every website has it. Until around five years ago with the advent of pop-up blockers, Javascript removal tools, and ad-blocking tools, every website I visited spammed me with a torrent of flashing banner ads, pop-ups, and keyword advertising. Somehow, the notion goes, enough people would actually click on that crap and buy whatever it was that was being advertised. The advertising revenue would keep the servers running and provide the blog/newspaper authors with a small paycheck.
Personally, I can’t stand advertising in general. It gets in the way of whatever it is I’m trying to do, whether it be searching or browsing the internet, reading a print newspaper, or watching TV. Reading the paper or watching TV probably adds about fifteen minutes of sifting through all the ads or waiting through commercials to get to the rest of the TV show I want to watch or the newspaper article I want to read. I’ve never clicked on a banner ad, much less even bought something that was advertised in this manner. On the internet, it’s hard to manually filter out all the crap to get to what you want. Fortunately, current ad-blocking tools do a pretty good job. I’ve even forgotten how good a job they really do, for when I sit down in front of a computer without any ad-blocking software, the harassment of flashing banners and keyword ads drive me up the wall.
Though internet advertising revenue has increased in the last year, it is predicted to fall in 2009. Everyone is finally getting sick of all the junk constantly being pushed at them as advertising approaches levels seen in “Idiocracy” and methods used in “Minority Report.” A great argument against internet advertising states that it is “not trusted, not wanted, and not needed.” While print newspapers are folding due to declining subscriptions, content providers on the internet are worried about a similar fate due to declining ad revenue. Ironically, the print newspapers mainly blame their plight on the shift to electronic media. To that end, content providers are considering increasing their usage of a second tool to provide revenue: yet another access cost.
Most online newspaper websites and online offerings of network TV shows do so with fairly low restrictions on who accesses their content. The front page stories for nearly every newspaper are available online as well as last night’s Lost episode. This freedom of access is what makes the internet so great: once you get in, there are few barriers to access anything. However, the same people that brought you bundled internet access want to change that. One media executive says, “We want to change consumer behavior somewhat, so the expectation that everything online is free has to change.” If this expectation changes, the internet as we know it is finished. It is the freedom and openness of the internet that makes it as valuable as it is. You can find anything or anyone and learn about nearly any topic available. On the internet, you can collaborate with people half a world away. The introduction of a second access cost for some internet content will most likely remove that openness. The effort to preserve network neutrality has been in place for several years, but now it may be coming to an end. Several ISPs are currently proposing pay access for channels and TV shows online. The movement of this business model may force providers of other media to do the same. Original sources will become locked down, leaving open and collaborative efforts to rot without them, such as Wikipedia, or IMDB. Someone may want you to look at a video posted to YouTube, but you can’t look at it because you don’t have the money to pay the access fee.
Nobody really wants to pay a pile of access fees to get the latest news, or even to watch videos on the internet, especially when an ISP is charging a significant monthly fee just to get online (though some say they are). The problem is that the annoyance and unprofitability of internet advertising is forcing a shift to another solution to prop up content providers. If the shift to selling access to content goes too far, the internet may become segmented into a large number of tiers, causing the digital divide to span both the physical and electronic worlds.
Microfracture: +7 months
Posted by Matt in microfracture on March 27, 2009
It’s been over seven months since the surgery and there are days I don’t think much about my knee. It just works like it’s supposed to. No more painful popping. Sometimes it does pop on the inside, which I think is some kind of compensation due to the new tissue growth on the outside, where the damage was. It probably isn’t very smooth in there.
I still haven’t tried running yet. With a lot of work for school, the immense overhead of returning to running is just too much. With past running injuries, there is so much time that is needed for walk/jog, cross training, and way more stretching and icing to deal with potential comeback injuries. When work subsides some, hopefully within a month or two, I should have more time to try running again. With the biking that I’ve done, I’m fairly confident that my knee will tolerate some running. Otherwise, I’ve got a feeling that I would have some pain on the bike.
My bike got a flat from the resistance trainer this week. I find that odd. The tire rubs against a smooth surface on the trainer, so it wasn’t punctured. I have a feeling that the rubber tube degrades over time and eventually the glue and seams that hold it together come apart. It was probably a pinch flat: as air slowly leaked out, the underinflated tire was pinched by the rim, causing a small tear in a seam. I did notice this week that the resistance didn’t seem as much as usual although I had recently put air in the tire. This morning it was flat, and five minutes after putting in more air, it was flat again. After a tube change, the resistance seemed more normal, but I always get real paranoid about stuff like this when biking. Sooner or later, something’s going to give. It’s why I like running: no equipment to rely on.
It’s almost as if with biking, some of my stress-induced injuries that would occur with running get transferred to the bike. With running or biking, there is a single entity performing the activity with the same probability of some kind of failure. With running, it’s just me, but with biking, the bike and I are sharing the task. Sometimes I break down, and sometimes the bike breaks down. In most cases, the bike can be fixed a lot faster than I can.
I’m still considering getting a new bike, but haven’t looked into it too much. I would like a carbon fiber frame, but that jacks up the price significantly. I know Trek has a fairly wide range of relatively affordable carbon fiber bikes, but it seems that some are better than others, so I’ll have to do research. The aluminum frames I’ve ridden feel kind of twisty while the steel-framed Bianchi I’ve got is solid. The components on the Bianchi are about ground to dust so I’ve got to get something that’s fairly robust. I figure that shelling out a bit of dough will be worth it if it’s something I’m going to use every day. Like the computer monitor, I would rather pay a bit more for something that’s good and that will work well and hold up than get something cheap that will break down. If I start running again, I’ll probably not bike as much, but I would probably still do it to help ease the impact of just running and doing nothing else.
For now, I’ve got no reason to rush anything, and when the time is right, I’ll look more into running again. I do think that time is coming soon.
