As you may know, I allow anonymous comments on this blog. Generally, when a blog is small, you don't want to do too much to discourage participation. Making people sign up for an account (particularly with email verification) is too much of a barrier when your comment volume is small. You can't allow raw posting these days because of spammers -- you need some sort of captcha or other proof-of-humanity -- but in most cases moderate readership sites can allow fairly easy participation.
Internet economics, technology and issues
Ok, admit it, who likes blogging in to a vacuum. You want to know how many people are actually reading your blog.
I have created a simple Perl script that scans your blog's log file and attempts to calculate how many people read the blog and the RSS feeds.
You can download the feed reader script. I release it under GPL2.
Recently, while keynoting the Freedom 2 Connect conference in Washington, I spoke about some of my ideas for fiber networks being built from the ground up. For example, I hope for the day when cheap kits can be bought at local stores to fiber up your block by running fiber through the back yards, in some cases literally burying the fiber in the "grass roots."
Over the weekend I was at the [BIL conference]http://www.bilconference.com, a barcamp/unconference style justaposition on the very expensive TED conference. I gave a few talks, including one on self driving cars, privacy and AI issues.
The conference, being free, was at a small community center. This location did not have internet. Various methods were possible to provide internet. The easiest are routers which can take cellular network EVDO cards and offer an 802.11 access point. That works most places, but is not able to handle many people, and may or may not violate some terms of service. However, in just about all these locations there are locations very nearby with broadband internet which can be used, including hotels, businesses and even some private homes. But how to get the access in quickly?
What would be useful would be an "instant internet kit" with all you need to take an internet connection (or two) a modest distance over wireless. This kit would be packed up and available via courier to events that want internet access on just a couple of days notice.
What would you put in the kit?
As our devices get more and more complex, configuring them gets harder and harder. And for members of the non-tech-savvy public, close to impossible.
Here's an answer: Develop a simple browser plug-in for all platforms that can connect a USB peripheral to a TCP socket back to the server where the plugin page came from. (This is how flash and Java applets work, in fact this could be added to flash or Java.)
I'm a director of BitTorrent Inc. (though not speaking for it) and so the recent debate about P2P applications and ISPs has been interesting to me. Comcast has tried to block off BitTorrent traffic by detecting it and severing certain P2P connections by forging TCP reset packets. Some want net neutrality legislation to stop such nasty activity, others want to embrace it. Brett Glass, who runs a wireless ISP, has become a vocal public opponent of P2P.
Some base their opposition on the fact that since BitTorrent is the best software for publishing large files, it does get used by copyright infringers a fair bit. But some just don't like the concept at all. Let's examine the issues.
A broadband connection consists of an upstream and downstream section. In the beginning, this was always symmetric, you had the same capacity up as down. Even today, big customers like universities and companies buy things like T-1 lines that give 1.5 megabits in each direction. ISPs almost always buy equal sized pipes to and from their peers.
With aDSL, the single phone wire is multiplexed so that you get much less upstream than downstream. A common circuit will give 1.5mbps down and say 256kb up -- a 6 to 1 ratio. Because cable systems weren't designed for 2 way data, they have it worse. They can give a lot down, but they share the upstream over a large block of customers under the existing DOCSIS system. They also will offer upstream on near the 6 to 1 ratio but unlike the DSL companies, there isn't a fixed line there.
Bruce Schneier has made a fuss by writing about how he leaves his wireless internet open. As a well regarded security expect, how can he do this. You'll see many arguments for and against in his posting. I'll expand on one of mine.
Part of Bruce's argument is one I express different. I sometimes say "Firewalls are a hoax." They are the wrong choice for security, but we sell them as a good choice. Oddly, however, this very fact does make them a valid choice. I will explain the contradiction.
If you have bought a home router or access point, you know it comes by default listening to some NAT based IP address, and the setup guide tells the user to type "http://192.168.1.1" or similar into their browser.
I may be on the extreme, but I use hundreds of different E-mail addresses. Since I have whole domains where every address forwards to me (or to my spam filters) I actually have an uncountable number of addresses, but I also have a very large number of real ones I use. That's because I generate a new address for every web site I enter an E-mail address on. It lets me know who sells or loses my address, and lets me cut off or add filtering to mail from any party. (By the way, most companies are very good, and really don't sell your E-mail.)
I'm quite impressed with Google's mobile maps application for smartphones. It works nicely on the iPhone but is great on other phones too.
Among other things, it will display live traffic on your map. And I recently saw, when asking it for directions, that it told me that there would be "7 minutes of traffic delay" along my route. That's great.
For various reasons, a wide variety of otherwise free wifi hotspots require you to go through a login screen. (This is also common of course with for-pay hotspots where you must enter an account or room number.)
Earlier I wrote about the frenzy buying Plastation 3s on eBay and lessons from it. There's a smaller scale frenzy going on now about the iPhone, which doesn't go on sale until 6pm today. With the PS3, many stores pre-sold them, and others lined up. In theory Apple/AT&T are not pre-selling, and limiting people to 2 units, though many eBay sellers are claiming otherwise.
The going price for people who claim they have one, either for some unstated reason, or because they are first in line at some store, is about $1100, almost twice the cost. A tidy profit for those who wait in line, time their auction well and have a good enough eBay reputation to get people to believe them. Quite a number of such auctions have closed at such prices with "buy it now." If you live in a town without a frenzy and line it might do you well to go down to pick up two iPods. Bring your laptop with wireless access to update your eBay auction. None of the auctions I have seen have gone so far as to show a picture of the seller waiting in line to prove it.
eBay has put down some hard terms on iPhone sellers and pre-sellers. It says it does not allow pre-sales, but seems to be allowing those sellers who claim they can guarantee a phone. It requires a picture of the actual item in hand, with a non-photoshopped sign in the picture with the seller's eBay name. A number of items show a stock photo with an obviously photoshopped tag. In spite of the publicised limit of 2, a number of people claim they have 4 or more.
It seems Apple may have deliberately tried to discourage this by releasing at 6pm on Friday, too late to get to Fedex in most places. Thus all most sellers can offer is getting the phone Monday, which is much less appealing, since that leaves a long window to learn that there are plenty more available Monday, and loses the all-important bragging rights of having an iPhone at weekend social events. Had they released it just a few hours earlier, I think sales like this would have been far more lucrative. (While Apple would not want to leave money on the table, it's possible high eBay prices would add to the hype and be in their interest.)
As before, I predict timing of auctions will be very important. At this point even a 1 day auction will close after 18 hours of iPhone sales, adding a lot of rish. The PS3 kept its high value for much of the Christmas season, but the iPhone, if not undersupplied, may drop to retail in as little as a day. A standard 1 week auction would be a big mistake. Frankly I think paying $1200 (or a $300 wait-in-line fee) is pretty silly.
The iPhone, by the way, seems like a cool generalized device. A handheld that has the basic I/O tools including GSM phone and is otherwise completely made of touchscreen seems a good general device for the future. Better with a small bluetooth keyboard. Whether this device will be "the one" remains to be seen, of course.
At Supernova 2007, several of us engaged Andrew Keen over his controversial book "The Cult of the Amateur." I will admit to not yet having read the book. Reviews in the blogosphere are scathing, but of course the book is entirely critical of the blogosphere so that's not too unexpected.
Recently, Lauren Weinstein posted a query for a way to bring a certain type of commentary on web sites to the web. In particular, he's interested in giving people who are the subject of attack web sites, who may even have gotten court judgments against such web sites to inform people of the dispute by annotations that show up when they search in search engines.
I'm not sure this is a good idea for a number of reasons. I like the idea of being able to see 3rd party commentary on web sites (such as Third Voice and others have tried to do) and suspect the browser is a better place than the search engine for it. I don't like putting any duty upon people who simply link to web sites (which is what search engines do) because the sites are bad. They may want to provide extra info on what they link to as a service to users, but that's up to them and should be unless they are a monopoly.
In addition, putting messages with an agenda next to search results is what search engines do for a living. However, in that may be the answer.
For many of us, E-mail has become our most fundamental tool. It is not just the way we communicate with friends and colleagues, it is the way that a large chunk of the tasks on our "to do" lists and calendars arrive. Of course, many E-mail programs like Outlook come integrated with a calendar program and a to-do list, but the integration is marginal at best. (Integration with the contact manager/address book is usually the top priority.)
You've all seen it many times. You hit the 'back' button and the browser tells you it has to resubmit a form, which may be dangerous, in order to go back. A lot of the blame for this I presume lies on pages not setting suitable cache TTLs on pages served by forms, but I think we could be providing more information here, even with an accurate cache note.
Most search engines now have a search box in the toolbar, which is great, and like most people mine defaults to Google. I can change the engine with a drop down menu to other places, like Amazon, Wikipedia, IMDB, eBay, Yahoo and the like. But that switch is a change in the default, rather than a temporary change -- and I don't want that, I want it to snap back to Google.
