The blogging world was stunned by the recent announcement by Google that it will be shutting down Google reader later this year. Due to my consulting relationship with Google I won’t comment too much on their reasoning, though I will note that I believe it’s possible the majority of regular readers of this blog, and many others, come via Google reader so this shutdown has a potential large effect here. Of particular note is Google’s statement that usage of Reader has been in decline, and that social media platforms have become the way to reach readers.
The effectiveness of those platforms is strong. I have certainly noticed that when I make blog posts and put up updates about them on Google Plus and Facebook, it is common that more people will comment on the social network than comment here on the blog. It’s easy, and indeed more social. People tend to comment in the community in which they encounter an article, even though in theory the most visibility should be at the root article, where people go from all origins.
However, I want to talk a bit about online publishing history, including USENET and RSS, and the importance of concepts within them. In 2004 I first commented on the idea of serial vs. browsed media, and later expanded this taxonomy to include sampled media such as Twitter and social media in the mix. I now identify the following important elements of an online medium:
- Is it browsed, serial or to be sampled?
- Is there a core concept of new messages vs. already-read messages?
- If serial or sampled, is it presented in chronological order or sorted by some metric of importance?
- Is it designed to make it easy to write and post or easy to read and consume?
Online media began with E-mail and the mailing list in the 60s and 70s, with the 70s seeing the expansion to online message boards including Plato, BBSs, Compuserve and USENET. E-mail is a serial medium. In a serial medium, messages have a chronological order, and there is a concept of messages that are “read” and “unread.” A good serial reader, at a minimum, has a way to present only the unread messages, typically in chronological order. You can thus process messages as they came, and when you are done with them, they move out of your view.
E-mail largely is used to read messages one-at-a-time, but the online message boards, notably USENET, advanced this with the idea of move messages from read to unread in bulk. A typical USENET reader presents the subject lines of all threads with new or unread messages. The user selects which ones to read — almost never all of them — and after this is done, all the messages, even those that were not actually read, are marked as read and not normally shown again. While it is generally expected that you will read all the messages in your personal inbox one by one, with message streams it is expected you will only read those of particular interest, though this depends on the volume.
Echos of this can be found in older media. With the newspaper, almost nobody would read every story, though you would skim all the headlines. Once done, the newspaper was discarded, even the stories that were skipped over. Magazines were similar but being less frequent, more stories would be actually read.
USENET newsreaders were the best at handling this mode of reading. The earliest ones had keyboard interfaces that allowed touch typists to process many thousands of new items in just a few minutes, glancing over headlines, picking stories and then reading them. My favourite was TRN, based on RN by Perl creator Larry Wall and enhanced by Wayne Davison (whom I hired at ClariNet in part because of his work on that.) To my great surprise, even as the USENET readers faded, no new tool emerged capable of handling a large volume of messages as quickly.
In fact, the 1990s saw a switch for most to browsed media. Most web message boards were quite poor and slow to use, many did not even do the most fundamental thing of remembering what you had read and offering a “what’s new for me?” view. In reaction to the rise of browsed media, people wishing to publish serially developed RSS. RSS was a bit of a kludge, in that your reader had to regularly poll every site to see if something was new, but outside of mailing lists, it became the most usable way to track serial feeds. In time, people also learned to like doing this online, using tools like Bloglines (which became the leader and then foolishly shut down for a few months) and Google Reader (which also became the leader and now is shutting down.) Online feed readers allow you to roam from device to device and read your feeds, and people like that. read more »

Interesting article about a new plan for mesh networking Android phones if the cell network fails. I point this out because of another blog post of mine from 2005 on a related proposal from Klein Gilhousen that he was pushing after Katrina.
The wifi mesh has the problem that wifi range is not going to get much better then 30-40m, and so you need a very serious density of phones to get a real mesh going, especially to route IP as this plan wishes to. Klein’s plan was to have the phones mesh over the wireless bands that were going unusued when the cell networks were dead (or absent in the wilderness.) The problem with his plan was that phone tranceivers tend to not be able to transmit and receive on the same bands, they need a cell tower. He proposed new generations of phones be modified to allow that.
But it hasn’t happened, in spite of being an obviously valuable thing in disasters. Sure there are some interference issues at the edges of legitimate cell nets, but they could be worked out. Cell phones are almost exclusively sold via carriers in the many countries, including the USA. They haven’t felt it a priority to push for phones that can work without carriers.
I suspect trying to route voice or full IP is also a mistake, especially for a Katrina like situation. There the older network technologies of the world, designed for very intermittent connectivity, make some sense. A network designed to send short text messages, a “short message service” if you will, using mesh principles combined with store and forward could make sure texts got to and from a lot of places. You might throw in small photos so trapped people could do things like send photos of wounds to doctors.
Today’s phones have huge amounts of memory. Phones with gigabytes of flash could store tens to hundreds of millions of passing (compressed and encrypted) texts until work got out that a text had been delivered. Texts could hop during brief connections, and airplanes, blimps and drones could fly overhead doing brief data syncs with people on the ground. (You would not send every text to every phone, but every phone would know how many hops it has been recently from the outside, and you could send always upstream.) A combination of cell protocols when far and wifi when close (or to those airplanes) could get decent volumes of data moving.
Phones would know if they were on their own batteries, or plugged into a car or other power source, and the ones with power would advertise they can route long term. It would not be perfect but it would be much better than what we have now.
But the real lament is that, as fast as the pace of change is in some fields of mobile, here we are 7.5 years after Katrina, having seen several other disasters that wiped out cell nets, and nothing much has changed.

Like most people, I have a lot of different passwords in my brain. While we really should have used a different system from passwords for web authentication, that’s what we are stuck with now. A general good policy is to use the same password on sites you don’t care much about and to use more specific passwords on sites where real harm could be done if somebody knows your password, such as your bank or email.
The problem is that over time you develop many passwords, and sometimes your browser does not remember them for you. So you go back to a site and try to log in, and you end up trying all your old common passwords. The problem: At many sites, if you enter the wrong password too many times, they lock you out, or at least slow you down. That’s not unwise on their part, but a problem for you.
One solution: Sites can remember hashes of your old passwords. If you type in an old password, they can say, “No, that used to be your password but you have a new one now.” And not count that as a failed attempt by a password cracker. This adds a very slight risk, in that it lets a very specific attacker who knows you super well get a few free hits if they have managed to learn your old passwords. But this risk is slight.
Of course they should store a hash of the password, not the actual password. No site should store the actual password. If a site can offer to mail you your old password rather than offering a link to reset the password, it means they are keeping it around. That’s a security risk for you, and also means if you use a common password on such sites, they now know it and can log in as you on all the other sites you use that password at. Alas, it’s hard to tell when creating an account whether a site stores the password or just a hash of it. (A hash allows them to tell if you have typed in the right password by comparing the hash of what you typed and the stored hash of the password back when you created it. A hash is one-way so they can’t go from the hash to the actual password.) Alas, only a small minority of sites do this right.
This is just one of many things wrong with passwords. The only positive about them is you can keep a password entirely in your memory, and thus go to a random computer and login without anything but your brain. That is also part of what is wrong with them, in that others can do that too. And that the remote computers can quite easily be compromised and recording the password. The most secure systems use the combination of something in your memory and information in a device. Even today, though, people are wary of solutions that require them to carry a device. Pretty soon that will change and not having your device will be so rare as to not be an issue.

I’m back from our fun “Singuarlity Week” in Tel Aviv, where we did a 2 day and 1 day Singularity University program. We judged a contest for two scholarships by Israelis for SU, and I spoke to groups like Garage Geeks, Israeli Defcon, GizaVC’s monthly gathering and even went into the west bank to address the Palestinian IT Society and announce a scholarship contest for SU.
Of course I did more photography, though the weather did not cooperate. However, you will see six new panoramas on my Israel Panorama Page and my Additional Israeli panoramas. My favourite is the shot of the western wall during a brief period of sun in a rainstorm.
In Ramallah, the telecom minister for the Palestinian Authority asked us, jokingly, “how can this technology end the occupation?” But I wanted to come up with a serious answer. Everybody who goes to the middle east tries to come up with a solution or at least some sort of understanding. Israelis get a bit sick of it, annoyed that outsiders just don’t understand the incredible depth and nuance of the problem. Outsiders imagine the Israelis and Palestinians are so deep in their conflict that they are like fish who no longer see the water.
In spite of those warnings, here’s my humble proposal for how to use new media technology to help.
Take classrooms of Israelis and classrooms of Palestinians and give them a mandatory school assignment. Their assignment is to be paired with an online buddy from the “other side.” Students would be paired based on a matching algorithm, considering things like their backgrounds, language skills or languages and subjects they want to learn. The other student, with whom they would interact over online media and video-conferencing (like Skype or Google Hangouts,) would become a study partner and the students would collaborate on projects suitable to them. They might also help one another learn a language, like English, Arabic or Hebrew. Students would be encouraged to add their counterpart to their social networking circles.
Both students would also be challenged to write an essay attempting to see the world from the point of view of the other. They will not be asked to agree with it, but simply to be able to write from that point of view. And their counterpart must agree at the end that it mostly does reflect their point of view. Students would be graded on this.
It would be important not to have this be a “forced friendship.” The students would be told it was not demanded they forget their preconceptions; not demanded they agree with everything their counterpart says. In fact, they would be encouraged to avoid conflict, to not immediately contradict statements they think are false. That the goal is not to convince their counterpart of things but to understand and help them understand. And in particular, projects should be set up where the students naturally work together viewing the teachers as the common enemy.
At the end of the year, a meeting would be arranged. For example, west bank students would be thrilled at a chance to visit the beach or some amusement park. A meeting on the west bank border on neutral ground might make sense too, though parents would be paranoid about safety and many would veto trips by their children into the west bank.
Would this bring peace? Hardly on its own. But it would improve things if every student at least knew somebody from outside their world, and had tried to understand their viewpoint even without necessarily agreeing with it. And some of the relationships would last, and the social networks would grow. Soon each student would have at least one person in their network from outside their formerly insular world. This would start with some schools, but ideally it would be something for every student to do. And it could even be expanded to include online pen-pals from other countries. With some students it would fail, particularly older ones whose views are already set. Alas, for younger ones, finding a common language might be difficult. Few Israelis learn Arabic, more Palestinians learn Hebrew and all eventually want to learn English. Somebody has to provide computers and networking to the poorer students, but it seems the cost of this is small compared to the benefit.

Back to wishlists on credit cards: Every year, for tax time, I go over my downloaded credit card records and I classify them into categories. I could just try to divide out the business and personal expenses (which I handle by having credit cards for business only and for personal only) but I try to do a bit more categorization, and from time to time there’s a reason I don’t follow the strict rule about what card to use.
So I would like, when I do an online purchase, to have an optional field in the form in which I can type anything. This would get put in or added to the memo field that you get when you download your transactions into accounting software. A quick script could then turn these memos into the categories we need for accounting.
Since getting a new field in forms is a lot of work, card companies could also offer me a small set of similar card numbers, though there might be only one on the physical card. This could be used to do some very basic categorization on the same card. They would all download to the same account, but the last digit would show up in the memo field. I know there are cards that issued a new number for every internet transaction back in the more paranoid days, but I’m talking about a series of cards where only one digit changes (if accepted by the processors because they pass it fully along,) and I can fill in the digit I like for a given transaction. (If I wish I could also get another card made of course. In fact, that would be handy if I decide to get two cards on the same account when giving a sub-card to a family member but not wanting a completely independent account for them.)
Anybody do this?

Over the years I have come to the maxim that “Everything should be as secure as is easy to use, and no more secure” to steal a theme from Einstein. One of my peeves has been the many companies who, feeling that E-mail is insecure, instead send you an E-mail that tells you you have an E-mail if you would only log onto their web site (often one you rarely log into) with the password you set up 2 years ago to read it. I often get these for things like bills and statements — “Your statement is now available online.” A few nicer ones tell me that my statement is online but the e-maiil does contain the total in the statement. Only if the total is unexpected do I need to login to see the statement.
None of these sites seem to offer me the option of saying, “My E-mail is secure, at least if you are doing your job, so just send me the data in E-mail” or of using one of the end-to-end encrypted E-mail systems. Alas, there is more than one E-mail system, but it’s not hard to do the two most popular, PGP/GPG and S-Mime and they are fairly widely supported in mailers.
As I noted, my own mail is secure in that I run an SMTP server on my home server, and only access it over encrypted IMAP. If they have set up their server to do encrypted SMTP (which should be the default by now, frankly) then the mail is generally secure (though it does do a brief unencrypted stop at my spam filter system.)
However, somtimes the contents of the mail need no security, and so instead it’s just annoyance. I have an acccount with Wachovia bank, and yesterday got an E-mail that there was an “important, secure E-mail” I should read on their server. After logging in, I found that all they had to say was public information about their merger with Wells Fargo, and how accounts would be shifted over. There was no reason that needed to be secure, since the only secret to reveal was that I had an account there, and the E-mail revealed that.
So I wrote a note back to complain, telling them not to make me jump through hoops to read public information. What’s so much fun is the response I got back:
Thank you for contacting Wachovia. My name is Tulanee E, and I am happy
to assist you.
Mr. Templeton, I would be happy to assist you. However, to guarantee the

Almost all credit cards will let you download transactions. Many will e-mail you a balance or payment reminder once a month, or a warning if your balance goes above a certain amount. And I’ve seen a small number that will e-mail you on every transaction.
But does anybody have a smart notification system which I can set, allowing me to be comfortable that there is no misuse of my card without filling my mailbox?
- At a basic level, notification (email or SMS) of transactions above a certain amount
- Combine that with notification when a group of small transactions exceed a set amount or an amount of time goes by (E-mail only)
- “You don’t need to notify me of this transaction” for your repeating transactions
- Easy console to turn on or off warnings and fraud alerts on foreign locations
For those of us who are on e-mail or SMS literally every day, this is a lot better fraud protection for us than the systems they use now, especially the one that find us with denied transactions in unusual places.
Update: Thanks to all commenters — some cards are providing many of these services.

This time of year I do a lot of online shopping, and my bell rings with many deliveries. But today and tomorrow, not Saturday. The post office comes Saturday but has announced it wants to stop doing that to save money. They do need to save money, but this is the wrong approach. I think the time has come for Saturday and Sunday delivery to be the norm for UPS, Fedex and the rest.
When I was young almost all retailers closed on Sunday and even had limited hours on Saturday. Banks never opened on the weekend either. But people soon realized that because the working public had the weekend off, the weekend was the right time for consumer services to be operating. The weekend days are the busiest days at most stores.
The shipping companies like Fedex and UPS started up for business to business, but online shopping has changed that. They now do a lot of delivery to residences, and not just at Christmas. But Thursday and Friday are these odd days in that business. An overnight package on Friday gets there 3 days later, not 1. (If you use the post office courier, you get Saturday delivery as part of the package, and the approximately 2 day Priority mail service is a huge win for things sent Thursday.) In many areas, the companies have offered Saturday and even Sunday delivery, but only as a high priced premium service. Strangely, the weekend also produces a gap in ground shipping times — the truck driving cross-country presumably pauses for 2 days.
We online shoppers shop 7 days a week and we want out stuff as soon as we can get it. I understand the desire to take the weekend off, but usually there are people ready to take these extra shifts. This will cost the delivery companies more as they will have to hire more workers to operate on the weekend. And they can’t just do it for ground (otherwise a 3 day package sent Friday arrives the same time as an overnight package.)
Update: I will point out that while online shipping is the David to the Goliath of brick & mortar, changing shipping to 7 days a week will mean a bunch more stuff gets bought online, and shipped, and will bring new revenue to the shipping companies. It’s just just a cost of hiring more people. It also makes use of infrastructure that sits idle 2 days a week.
This is particularly good for those who are always not hope to sign for packages that come during the work week. The trend is already starting. OnTrak, which has taken over a lot of the delivery from Amazon’s Nevada warehouse to Californians, does Saturday delivery, and it’s made me much more pleased with Amazon’s service. When Deliverbots arrive, this will be a no brainer.

I’m actually not a fan of login and sessions on the web, and in fact prefer a more stateless concept I call authenticated actions to the more common systems of login and “identity.”
But I’m not going to win the day soon on that, and I face many web sites that think I should have a login session, and that session should in fact terminate if I don’t click on the browser often enough. This frequently has really annoying results — you can be working on a complex form or other activity, then switch off briefly to other web sites or email to come back and find that “your session has expired” and you have to start from scratch.
There are times when there is an underlying reason for this. For example, when booking things like tickets, the site needs to “hold” your pending reservation until you complete it, but if you’re not going to complete it, they need to return that ticket or seat to the pool for somebody else to buy. But many times sessions expire without that reason. Commonly the idea is that for security, they don’t want to leave you logged on in a way that might allow somebody to come to your computer after you leave it and take over your session to do bad stuff. That is a worthwhile concept, particularly for people who will do sessions at public terminals, but it’s frustrating when it happens on the computer in your house when you’re alone.
Many sites also overdo it. While airlines need to cancel your pending seat requests after a while, there is no reason for them to forget everything and make you start from scratch. That’s just bad web design. Other sites are happy to let you stay “logged on” for a year.
To help, it would be nice if the browser had a way of communicating things it knows about your session with the computer to trusted web sites. The browser knows if you have just switched to other windows, or even to other applications where you are using your mouse and keyboard. Fancier tools have even gone so far as to use your webcam and microphone to figure if you are still at your desk or have left the computer. And you know whether your computer is in a public space, semi-public space or entirely private space. If a browser, or browser plug-in, has a standardized way to let a site query session status, or be informed of session changes and per-machine policy, sites could be smarter about logging you out. That doesn’t mean your bank still should not be paranoid if you are logged in to a session where you can spend your money, but they can be more informed about it. read more »

Today an op-ed by John Sununu and Harold Ford Jr. of “Broadband For America” (a group of cable companies and other ISPs which says it is really a grass-roots organization) declared that the net needs a better pricing model for what Netflix is doing. For a group of ISPs, they really seem to not understand how the internet works and how pricing works, so I felt it was worthwhile to describe how things work with a remarkably close analogy. (I have no association with Netflix, I am not even a customer, but I do stream video on the net.)
You can liken the internet to a package delivery service that works somewhat differently from traditional ones like the postal service or FedEx. The internet’s pricing model is “I pay for my line to the middle, and you pay for your line to the middle and we don’t account for the costs of individual traffic.”
In the package model, imagine a big shipping depot. Shippers send packages to this depot, and it’s the recipient’s job to get the package from the depot to their house. The shippers pay for their end, you pay for your end, and both share the cost of creating the depot.
Because most people don’t want to go directly to the depot to get their packages, a few “last mile” delivery companies have sprung up. For a monthly fee, they will deliver anything that shows up at the depot addressed to you directly to your house. They advertise in fact, that for the flat fee, they will deliver as many packages as show up, subject to a fairly high maximum rate per unit of time (called bandwidth in the internet world.) They promote and compete on this unlimited service.
To be efficient, the delivery companies don’t run a private truck from the depot to your house all the time. Instead, they load up a truck with all the packages for your neighbourhood, and it does one delivery run. Some days you have a lot of packages and your neighbours have few. Other days you have few and they have a lot. The truck is sized to handle the high end of the total load for all the neighbours. However, it can’t handle it if a large number of the neighbours all want to use a large fraction of their total load on the same day, they just didn’t buy enough trucks for that, even though they advertised they were selling that.
This is not unreasonable. A majority of the businesses in the world that sell flat rate service work this way, not just internet companies. Though there are a few extra twists in this case:
- The last mile companies have a government granted franchise. Only a couple can get permission to operate. (In reality — only a few companies have got permission to have wires strung on poles or under the street.)
- Some of the last mile companies also used to be your exclusive source for some goods (in this case phone service and TV) and are concerned that now there are competitors delivering those things to the customers.
The problem arises because new services like Netflix suddenly have created a lot more demand to ship packages. More than the last mile companies counted on. They’re seeing the truck fill up and need to run more trucks. But they proudly advertised unlimited deliveries from the depot to their customers. So now, in the op-ed, they’re asking that companies like Netflix, in addition to paying the cost of shipping to the depot, pay some of the cost for delivery from the depot to the customer. If they did this, companies would pass this cost on to the customer, even though the customer already paid for that last mile delivery. read more »

ICANN is meeting in San Francisco this week. And they’re getting closer to finally implementing a plan they have had in the works for some time to issue new TLDs, particularly generic top level domains.
Their heart is in the right place, because Verisign’s monopoly on “.com” — which has become the de facto only space where everybody wants a domain name, if they can get it — was a terrible mistake that needs to be corrected. We need to do something about this, but the plan of letting other companies get generic TLDs which are ordinary English words, with domains like “.sport” and “.music” (as well as .ibm and .microsoft) is a great mistake.
I have an odd ambivalence. This plan will either fail (as the others like .travel, .biz, .museum etc appear to have) or it will succeed at perpetuating the mistake. Strangely it is the trademark lawyers who know the answer to this. In trademark law, it was wisely ruled centuries ago that nobody gets ownership of generic terms. But some parties will offer the $185,000 fee to own .music precisely because they hope it will give them a monopoly on naming of music related internet sites. Like all monopolies these TLDs will charge excessive fees and give poor customer service. They’ll also get to subdivide the monopoly selling domains like rock.music or classical.music. And while .music will compete with .com, the new TLDs will largely not compete with one another — ie. nobody will be debating whether to go with .music or .sport, and so we won’t get the competition we truly need.
I’ve argued this before, but I have just prepared two new essays in my DNS sub-site:
Since I don’t like either of the two main consequences, what do I propose? Well for years I have suggested we should instead have truly competitive TLDs which can compete on everything — price, policies, service, priority and more. They should each start on an equal footing so they are equal competitors. That means not giving any one a generic name that has an intrinsic value like “.music.” People will seek out the .music domain not because the .music company is good or has good prices, they will seek it out because they want to name a site related to music, and that’s not a market.
Instead I propose that new TLDs be what trademark people call “coined terms” which are made up words with no intrinsic meaning. Examples from the past include names like Kodak, Xerox and Google. Today, almost every new .com site has to make up a coined term because all the generics are taken. If the TLDs are coined terms, then the owners must build the value in them by the sweat of their brow (or with mone) rather than getting a feudal lordship over an existing space. That means they can all compete for the business of people registering domains, and competition is what’s good for the market and the users.
Sadly the .com monopoly remains (along with the few other generic TLDs.) The answer there is to announce a phase out. All .com sites with generic meanings should get new names in the new system, but after a year or two they’ll get redirect as long as they want to pay. (Their new registrar will manage this and set the price.) All http requests, in particular would get an HTTP Redirect Permanent (301) so the browser shows the new name. E-mail MX would be provided but all sent email would use the new name. All old links and addresses would still work forever, but users would switch advertising and everything else to the new names at a reasonable pace. Yes, people who invested lots of money in trying to own words like “drugstore.com” lose some of that value, but it’s value they should never have been sold in the first place. (Companies with unique strings like microsoft.com could avoid the switch, but not non-unique ones like apple.com or ibm.com)
Check out the essays for the real details. Of course, at this point the forces of the “stakeholders” at ICANN are so powerful that I am tilting at windmills. They will go ahead even though it’s the wrong answer. And once done, it will be as hard to undo as .com is. But the right answer should still be proclaimed.

In media today, it’s common to talk about three screens: Desktop, mobile and TV. Many people watch TV on the first two now, and tools like Google TV and the old WebTV try to bring interactive, internet style content to the TV. People like to call the desktop the “lean forward” screen where you use a keyboard and have lots of interactivity, while the TV is the “lean back” couch-potato screen. The tablet is also distinguishing itself a bit from the small screen normally found in mobile.
More and more people also find great value in having an always-on screen where they can go to quickly ask questions or do tasks like E-mail.
I forecast we will soon see the development of a “fourth screen” which is a mostly-always-on wall panel meant to be used with almost no interaction at all. It’s not a thing to stare at like the TV (though it could turn into one) nor a thing to do interactive web sessions on. The goal is to have minimal UI and be a little bit psychic about what to show.
One could start by showing stuff that’s always of use. The current weather forecast, for example, and selected unusual headlines. Whether each member of the household has new mail, and if it makes sense from a privacy standpoint, possibly summaries of that mail. Likewise the most recent status from feeds on twitter or Facebook or other streams. One could easily fill a screen with these things so you need a particularly good filter to find what’s relevant. Upcoming calendar events (with warnings) also make sense.
Some things would show only when important. For example, when getting ready to go out, I almost always want to see the traffic map. Or rather, I want to see it if it has traffic jams on it, no need to show it when it’s green — if it’s not showing I know all is good. I may not need to see the weather if it’s forecast sunny either. Or if it’s raining right now. But if it’s clear now and going to rain later I want to see that. Many city transit systems have a site that tracks when the next bus or train will come to my stop — I want to see that, and perhaps at morning commute time even get an audio alert if something unusual is up or if I need to leave right now to catch the street car. A view from the security camera at the door should only show if somebody is at the door.
There are so many things I want to see that we will need some UI for the less popular ones. But it should be a simple UI, with no need to find a remote (though if I have a remote — any remote — it should be able to use it.) Speech commands would be good to temporarily see other screens and modes. A webcam (and eventually Kinect style sensor) for gestural UI would be nice, letting me swipe or wave to get other screens. read more »

You may have heard of Bus Rapid Transit — a system to give a bus line a private or semi-private right-of-way, along with bus stops that are more akin to stations than bus shelters (with ticket-taking machines and loading platforms for multiple doors.) The idea is to make bus transit competitive with light-rail (LRT) in terms of speed and convenience. Aside from getting caught in slow traffic, buses also are slow to board. BRT is hoped to be vastly less expensive than light rail — which is not hard because LRT (which means light capacity rail, not lightweight rail) has gotten up to $80 to $100M per mile. When BRT runs down the middle of regular roads, it gets signal timing assistance to help it have fewer stops. It’s the “hot new thing” in transit. Some cities even give it bits of underground or elevated ROW (the Boston Silver Line) and others just want to wall off the center of a road to make an express bus corridor. Sometimes BRT gets its own highway lane or shares a special carpool lane.
At the same time just about anybody who has looked at transit and the internet has noticed that as the buses go down the street, they travel with tons of cars carrying only one person and lots of empty seats. Many have wondered, “how could we use those empty private car seats to carry the transit load?” There are a number of ride-sharing and carpooling apps on web sites and on smartphones, but success has been modest. Drivers tend to not want to take the time to declare their route, and if money is offered, it’s usually not enough to counter the inconvenience. Some apps are based on social networks so friends can give rides to friends — great when it works but not something you can easily do on demand.
But one place I’ve seen a lot of success at this is the casual carpooling system found in a number of cities. Here it’s very popular to cross the Oakland-SF Bay Bridge, which has a $6 toll to cross into SF. It used to be free for 3-person carpools, now it’s $2.50, but the carpools also get a faster lane for access to the highly congested bridge both going in and out of SF.
Almost all the casual carpool pickup spots coming in are at BART (subway) stations, which are both easy for everybody to get to, and which allow those who can’t get a carpool to just take the train. There is some irony that it means that the carpools mostly take people who would have ridden BART trains, not people who would have driven, the official purpose of carpool subsidies. In the reverse direction the carpools are far fewer with no toll to be saved, but you do get a better onramp.
People drive the casual carpools because they get something big for for it — saving over $1,000/year, and hopefully a shorter line to the bridge. This is the key factor to success in ride share. The riders are saving a similar amount of money in BART tickets, even more if they skipped driving.
Let’s consider what would happen if you put in the dedicated lane for BRT, but instead of buses created an internet mediated carpooling system. Drivers could enter the dedicated lane only if:
- They declared their exit in advance to the app on their phone, and it’s far enough away to be useful to riders.
- They agree to pick up riders that their phone commands them to.
- They optionally get a background check that they pay for so they can be bonded in some way to do this. (Only the score of the background check is recorded, not the details.)
Riders would declare their own need for a ride, and to what location, on their own phones, or on screens mounted at “stops” (or possibly in nearby businesses like coffee shops.) When a rider is matched to a car, the rider will be informed and get to see the approach of their ride on the map, as well as a picture of the car and plate number. The driver will be signaled and told by voice command where to go and who to pick up. I suggest calling this Carpool-Rapid-Transit or CRT. read more »

Passwords are in the news thanks to Gawker media, who had their database of userids, emails and passwords hacked and published on the web. A big part of the fault is Gawker’s, who was saving user passwords (so it could email them) and thus was vulnerable. As I have written before, you should be very critical of any site that is able to email you your password if you forget it.
Some of the advice in the wake of this to users has been to not use the same password on multiple sites, and that’s not at all practical in today’s world. I have passwords for many hundreds of sites. Most of them are like gawker — accounts I was forced to create just to leave a comment on a message board. I use the same password for these “junk accounts.” It’s just not a big issue if somebody is able to leave a comment on a blog with my name, since my name was never verified in the first place. A different password for each site just isn’t something people can manage. There are password managers that try to solve this, creating different passwords for each site and remembering them, but these systems often have problems when roaming from computer to computer, or trying out new web browsers, or when sites change their login pages.
The long term solution is not passwords at all, it’s digital signature (though that has all the problems listed above) and it’s not to even have logins at all, but instead use authenticated actions so we are neither creating accounts to do simple actions nor using a federated identity monopoly (like Facebook Connect). This is better than OpenID too. read more »

Yesterday we had a meeting using some videoconferencing. In a situation I find fairly common, the setup was a meeting room with many people, and then a small number of people calling in remotely. In spite of this being a fairly common situation, I have had trouble finding conferencing systems that do this particular task very well. I have not been looking in the high-priced end but I believe the more modestly priced tools should be able to focus on this and make it work. Yesterday we used Oovoo, one of the few multi-part conference systems to support PC and Mac, with some good but many bad results.
The common answer, namely a speakerphone on the meeting room table and a conference bridge system, is pretty unsatisfactory, though the technology is stable enough that it is easy to get going. The remote people are never really part of the meeting. It’s harder for them to engage in random banter, and the call fidelity is usually low and never better than PSTN phone quality. They usually have trouble hearing some of the people in the meeting room, though fancier systems with remote microphones help a bit with that.
The audio level
The next step up is a higher quality audio call. For this Skype is an excellent and free solution. The additional audio quality offers a closer sense of being in the room, and better hearing in both directions. It comes with a downside in that tools like Skype often pick up ambient noise in the room (mostly with remote callers) including clacking of keyboards, random background noises and bleeps and bloops of software using the speakers of the computer. While Skype has very good echo cancellation for those who wish to use it in speakerphone mode, I still strongly recommend the use of headsets by those calling in remotely, and even the judicious use of muting. There’s a lot more Skype and others could do in this department, but a headset is a real winner, and they are cheap.
Most of these notes also apply to video calling which of course includes audio. read more »

Today an interesting paper (written with the assistance of the EFF) was released. The authors have found evidence that governments are compromising trusted “certificate authorities” by issuing warrants to them, compelling them to create a false certificate for a site whose encrypted traffic they want to snoop on.
That’s just one of the many ways in which web traffic is highly insecure. The biggest reason, though, is that the vast majority of all web traffic takes place “in the clear” with no encryption at all. This happens because SSL/TLS, the “https” system is hard to set up, hard to use, considered expensive and subject to many false-alarm warnings. The tendency of security professionals to deprecate anything but perfect security often leaves us with no security at all. My philosophy is different. To paraphrase Einstein:
Ordinary traffic should be made as secure as can be made easy to use, but no more secure
In this vein, I have prepared a new article on how to make the web much more secure, and it makes sense to release it today in light of the newly published threat. My approach, which calls for new browser behaviour and some optional new practices for sites, calls for the following:
- Make TLS more lightweight so that nobody is bothered by the cost of it
- Automatic provisioning (Zero UI) for self-signed certificates for domains and IPs.
- A different meaning for the lock icon: Strong (Locked), Ordinary (no icon) and in-the-clear (unlocked).
- A new philosophy of browser warnings with a focus on real threats and on changes in security, rather than static states deemed insecure.
- A means so sites can provide a file with advisories for browsers about what warnings make sense at this site.
There is one goal in mind here: The web must become encrypted by default, with no effort on the part of site operators and users, and false positive warnings that go off too frequently and make security poor and hard to use must be eliminated.
If you have interest in browser design and security policy I welcome your comments on A new way to secure the web.

I’m at DLD in Munich, and going to Davos tomorrow. While at DLD I made a brief mention during a panel on identity and tracking of my concept of the privacy dangers of the AIs of the future, which are able to extract things from recorded data (like faces) that we can’t do today.
I mentioned a new idea, however, which is a search engine which focuses on the negative, because though advanced algorithms it can tell the difference between positive and negative content.
We’re quite interested in dirt. Every eBay user who looks at a seller’s feedback would like to see only the negative comments, as the positive ones tell almost no information. eBay doesn’t want to show this, they want people to see eBay sellers as positive and to bid.
But a lot of the time if we are investigating a company we might do business with or even a person, we want to focus on the negative. A company with few complaints is of interest to us. AI software will exist to find such complaints, and possibly even to do things like understand photos and know which ones might be a source of embarrassment, or read on postings on message boards and tell which ones are damning. This is hard to do well today, but will change over time.
This will have deep consequences to concepts of reputation. Those with a big online presence certainly have bad stuff written by or about them out there. Normally, however, it is buried in the large volume of stuff, and doesn’t get high search engine rankings. However, our human thirst for gossip and dirt will result in some search engines will push it to the top. In addition, there will be those wanting to game this with deliberate libel of their enemies and competitors. Today they can do this but their libels will be hidden in the large volume of information.
Some have proposed that in the future it will be necessary to pay a service to libel you, and spread lots of false material that buries and discredits any libel left by enemies (as well as true negative comments.) The AIs may be able to spot the difference, but that’s an arms race which can’t easily be predicted.
It is likely that all the bad in our lives will haunt us even more than we already fear. Efforts by some countries to pass laws which let people delete alleged libels will not work, and may bring even more attention to the materials. While you might be able to remove your tag from a photo on facebook, once that photo makes it into a system that can do face recognition the tag will come back and do so in ways beyond your control.

These days it is getting very common to make videos of presentations, and even to do live streams of them. And most of these presentations have slides in Powerpoint or Keynote or whatever. But this always sucks, because the camera operator — if there is one — never moves between the speaker and the slide the way I want. You can’t please everybody of course.
In the proprietary “web meeting” space there are several tools that will let people do a video presentation and sync it with slides, ideally by pre-transmitting the slide deck so it is rendered in full resolution at the other end, along with the video. In this industry there are also some video players where you can seek along in the video and it automatically seeks within the slides. This can be a bit complex if the slides try to do funny animations but it can be done.
Obviously it would be nice to see a flash player that understands it is playing a video and also playing slides (even video of slides, though it would be better to do it in higher quality since it isn’t usually full motion video.) Sites like youtube could support it. However, getting the synchronization requires that you have a program on the presenting computer, which you may not readily control.
One simple idea would be a button the camera operator could push to say “Copy this frame to the slide window.” Then the camera would, when there is a new slide, move or switch over there, and the button would be pushed, and the camera could go immediately back to the speaker. Usually though the camera crew has access to the projector feed and would not need to actually point a camera, in fact some systems “switch” to the slides by just changing the video feed. A program which sends the projector feed with huge compresion (in other words, an I frame for any slide change and nothing after) would also work well. No need to send all the fancy transitions.
But it would be good to send the slides not as mpeg, but as PNG style, to be sharper if you can’t get access to the slides themselves. I want a free tool, so I can’t ask for the world, yet, but even something as basic as this would make my watching of remote presentations and talks much better. And it would make people watching my talks have a better time too — a dozen or so of them are out on the web.
I’m in O’Hare waiting to fly to Munich for DLD. More details to come.

There’s a phenomenon we’re seeing more and more often. A company screws over a customer, but this customer now has a means to reach a large audience through the internet, and as a result it becomes a PR disaster for the company. The most famous case recently was United Breaks Guitars where Nova Scotia musician David Carroll had his luggage mistreated and didn’t get good service, so he wrote a funny song and music video about it. 7 million views later, a lot of damage was done to United Airlines’ reputation.
I’ve done this myself to companies who refuse to fix things. I will write a page about the incident sometimes, and due to my high google pagerank, the page will show up high. Do a Google search for Qwest Long Distance and you’ll see the first hit is Qwest, and the 2nd is my boring but frustrating story of bad service. I’m not the only one to have done this. Over 200 people per month visit that page — which has been up for almost a decade — and you have to assume they have lost more business than it would have cost to make things right.
Now I think all good companies should make things right whenever they can to show that the errors are rare enough that they can afford to go the extra mile and fix them. If you won’t fix them, it means you must have a lot of them.
However, companies are soon going to realize that there are a whole raft of “minor celebrities” like David Carroll and even myself who can do far more damage than they can tolerate. Companies have always given top notch service to A-list celebrities, and even to B list. Not just gift bags at the Oscars. When I was kid, my father was A-list for a time in Canada, and that meant that when he got on a plane with a coach ticket, the flight attendant escorted him to first class. That was in the days before first class was always full due to upgrades, of course.
But there are tens of thousands, maybe hundreds of thousands of people who can be a risk for a company if they piss us off. All bloggers with a decent audience (and even some who have an audience that includes the A-list bloggers.) People with high search engine rank. People who can simply write well to get their story out there — in particular people who are good at making a story funny and entertaining. And of course, musicians and people who are good at video editing and producing viral videos. Perhaps them most of all.
So I predict that before long services will spring up to enumerate these D-list and E-list celebrities and potential celebs. Everybody will get graded. And a flag will show up in the customer service computer for the top few percentiles saying, “this one is an influencer.” It will say, “you are authorized, though you are just a script monkey customer rep, to do more for this customer.” Or you might just be direct right to a more powerful rep. This “long tail elite” may just start getting better service and even better deals, so long as they identify themselves first.
Companies have done this for some time based on how good a customer you are, ie. how much you spend. If you are a big spending customer, you get the magic 800 number or just get routed to the better service due to your frequent flyer number or even caller-ID. But I’m talking about doing this not just for those who spend a lot, but for those who influence a lot of spending — or could influence it in a negative way.
And of course they are working hard to make us identify ourselves in every transaction, just not yet for this. People who review products for a living will need to be sure they are anonymous when they buy and ask for service. But oddly, negative reviews from people who review stuff for a living are becoming less important than the horror story from the negative guy. Since most product reviewers at magazines are unwilling to go through the horrors of real customer service, they call the PR flacks and get top-rated service, and then explain in the review that they did this (if they are honest.)
If you’re not in the long-tail elite, this is all a bad sign. You’ll never get much satisfaction, and the number of horror stories on the net will go down below what the true level should be. Of course you will be able to join the long tail elite if you want to, since I am sure those who track it will note the names of people who regularly show up on consumer complaint message boards that have high readership or rank. But that’s a lot of work.
It doesn’t really do a lot of good for the rest of the world if perks are given to the long tail elite. Better just for companies to get good enough that they make mistakes rarely, and thus can afford to go the extra distance to fix them when it happens.

I think URL shorteners are are a curse, but thanks to Twitter they are growing vastly in use. If you don’t know, URL shorteners are sites that will generate a compact encoded URL for you to turn a very long link into a short one that’s easier to cut and paste, and in particular these days, one that fits in the 140 character constraint on Twitter.
I understand the attraction, and not just on twitter. Some sites generate hugely long URLs which fold over many lines if put in text files or entered for display in comments and other locations. The result, though, is that you can no longer determine where the link will take you from the URL. This hurts the UI of the web, and makes it possible to fool people into going to attack sites or Rick Astley videos. Because of this, some better twitter clients re-expand the shortened URLs when displaying on a larger screen.
Anyway, here’s an idea for the Twitter clients and URL shorteners, if they must be used. In a tweet, figure out how much room there is to put the compacted URL, and work with a shortener that will let you generate a URL of exactly that length. And if that length has some room, try to put in some elements from the original URL so I can see them. For example, you can probably fit the domain name, especially if you strip off the “www.” from it (in the visible part, not in the real URL.) Try to leave as many things that look like real words, and strip things that look like character encoded binary codes and numbers. Of course, in the end you’ll need something to make the short URL unique, but not that much. Of course, if there already is a URL created for the target, re-use that.
Google just did its own URL shortener. I’m not quite sure what the motives of URL shortener sites are. While sometimes I see redirects that pause at the intermediate site, nobody wants that and so few ever use such sites. The search engines must have started ignoring URL redirect sites when it comes to pagerank long ago. They take donations and run ads on the pages where people create the tiny URLs, but when it comes to ones used on Twitter, these are almost all automatically generated, so the user never sees the site.
