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.)
Internet economics, technology and issues
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.
While I was at Tim O'Reilly's Web 2.0 Expo, I did an interview with an online publication called Web Pro News. I personally prefer written text to video blogging, but for those who like to see video, you can check out:
The video quality is pretty good, if not the lighting.
I really wish I could find a really good calendaring tool. I've seen many of the features I want scattered in various tools, though some are nowhere to be found. I thought it would be good to itemize some of them. I'm mostly interested in *nix -- I know that on Windows, MS Outlook is the most common choice, with Exchange for sharing.
An eBay reputation is important if you're going to sell there. Research shows it adds a decent amount to the price, and it's very difficult to sell at all with just a few feedbacks. Usually sellers will buy a few items first to get a decent feedback -- sometimes even scam items sold just for feedback. Because savvy buyers insist on selling feedback, it's harder, and sometimes sellers will also sell bogus items just for feedback as a seller. eBay has considered offering a feedback score based on the dollar volume of positive and negative transactions but has not yet done this.
Yesterday I attended the online community session of Web2Open, a barcamp-like meeting going on within Tim O'Reilly's Web 2.0 Expo. (The Expo has a huge number of attendees, it's doing very well.)
I put forward a number of questions I've been considering for later posts, but one I want to make here is this: Where has the innovation been in online discussion software? Why are most message boards and blog comment systems so hard to use?
I know this is true because huge numbers of people are still using USENET, and not just for downloading binaries. USENET hasn't seen much technical innovation since the 80s. As such, it's aging, but it shouldn't be simply aging, it should have been superseded long ago. We've gone through a period of tremendous online innovation in the last few decades, unlike any in history. Other old systems, like the Well, continue to exist and even keep paying customers in spite of minimal innovation. This is like gopher beating Firefox, or a CD Walkman being superior in some ways to an iPod. It's crazy. (The users aren't crazy, it's the fact that their choice is right that's crazy.)
In many cities, the transit systems have GPS data on the vehicles to allow exact prediction of when trains and buses will arrive at stops. This is quite handy if you live near a transit line, and people are working on better mobile interfaces for them, but it's still a lot harder to use them at a remote location.
A friend (Larry P.) once suggested to me that he thought you could build a rural mobile phone much cheaper than Iridium network by putting nodes in all the airliners flying over the country. The airliners have power, and have line of sight to ground stations, and to a circle of about 200 miles radius around them. That's pretty big (125,000 square miles) and in fact most locations will be within sight of an airliner most of the time.
I've been seeing a lot of press lately worrying that the internet won't be able to handle the coming video revolution, that as more and more people try to get their TV via the internet, it will soon reach a traffic volume we don't have capacity to handle. (Some of this came from a Google TV exec's European talk, though Google has backtracked a bit on that.)
If you're like me, you select special unique passwords for the sites that count, such as banks, and you use a fairly simple password for things like accounts on blogs and message boards where you're not particularly scared if somebody learns the password. (You had better not be scared, since most of these sites store your password in the clear so they can mail it to you, which means they learn your standard account/password and could pretend to be you on all the sites you duplicate the password on.) There are tools that will generate a different password for every site you visit, and of course most browsers will remember a complete suite of passwords for you, but neither of these work well when roaming to an internet cafe or friend's house.
However, every so often you'll get a site that demands you use a "strong" password, requiring it to be a certain length, to have digits or punctuation, spaces and mixed case, or subsets of rules like these. This of course screws you up if the site is an unimportant site and you want to use your easy to remember password, you must generate a variant of it that meets their rules and remember it. These are usually sites where you can't imagine why you want to create an account in the first place, such as stores you will shop at once, or blogs you will comment on once and so on.
Strong passwords make a lot of sense in certain situations, but it seems some people don't understand why. You need a strong password in case it is possible or desireable for an attacker to do a "dictionary" attack on your account. This means they have to try thousands, or even millions of passwords until they hit the one that works. If you use a dictionary word, they can try the most common words in the dictionary and learn your password.
So many social networking sites (LinkedIn, Orkut, Friendster, Tribe, Myspace etc.) seem bent on being islands. But there can't be just one player in this space, not even one player in each niche. But when you join a new one it's like starting all over again. I routinely get invitations to join new social applications, and I just ignore them. It's not worth the effort.
It's more and more common today to see software that is capable of easily or automatically updating itself to a new version. Sometimes the user must confirm the update, in some cases it is fully automatic or manual but non-optional (ie. the old version won't work any more.) This seems like a valuable feature for fixing security problems as well as bugs.
But rarely do we talk about what a giant hole this is in general computer security. On most computers, programs you run have access to a great deal of the machine, and in the case of Windows, often all of it. Many of these applications are used by millions and in some cases even hundreds of millions of users.
When you install software on almost any machine, you're trusting the software and the company that made it, and the channel by which you got it -- at the time you install. When you have auto-updating software, you're trusting them on an ongoing basis. It's really like you're leaving a copy of the keys to your office at the software vendor, and hoping they won't do anything bad with them, and hoping that nobody untrusted will get at those keys and so something bad with them.
I was seduced by Google's bribe of $20 per $50 or greater order to try their new Checkout service, and did some Christmas shopping on buy.com. Normally buy.com, being based in Southern California, takes only 1 or 2 days by UPS ground to get things to me. So ordering last weekend should have been low risk for items that are "in stock and ship in 1-2 days." Yes, they cover their asses by putting a longer upper bound on the shipping time, but generally that's the ship time for people on the other coast.
I've spoken before about ZUI (Zero User Interface) and how often it's the right interface.
One important system that often has too complex a UI is backup. Because of that, backups often don't get done. In particular offsite backups, which are the only way to deal with fire and similar catastrophe.
Here's a rough design for a ZUI offsite backup. The only UI at a basic level is just installing and enabling it -- and choosing a good password (that's not quite zero UI but it's pretty limited.)
Normally I'm a general-purpose computing guy. I like that the computer that runs my TV with MythTV is a general purpose computer that does far more than a Tivo ever would. My main computer is normally on and ready for me to do a thousand things.
But there is value in specialty internet appliances, especially ones that can be very low power and small. But it doesn't make sense to have a ton of those either.
