We all know how annoying it is that today’s much faster computers take such a long time to boot, and OS developers are working on speeding it up. Some time ago I proposed a defragmenter that notice what blocks were read in what order at boot and put the contiguous on the disk. I was told that experiments with this had not had much success, but more recently I read reports of how the latest Linux distributions will boot as much a 3 times faster on solid state disks as on rotating ones. There are some SSDs with performance that high (and higher) but typical ones range more in the 120 mb/second rate, better than 80 mb/second HDDs but getting more wins from the complete lack of latency.
However, today I want to consider something which is a large portion of the boot time, namely the power-on-self-test or “POST.” This is what the BIOS does before it gets ready to load the real OS. It’s important, but on many systems is quite slow.
I propose an effort to make the POST multitask with the loading of the real OS. Particularly on dual-core systems, this would be done by having one core do the POST and other BIOS (after testing all the cores of course) and other cores be used by the OS for loading. There are ways to do all this with one core I will discuss below, but this one is simple and almost all new computers have multiple cores.
Of course, the OS has to know it’s not supposed to touch certain hardware until after the BIOS is done initializing it and testing it. And so, there should be BIOS APIs to allow the OS to ask about this and get events as BIOS operations conclude. The OS, until given ownership of the screen, would output its status updates to the screen via a BIOS call. In fact, it would do that with all hardware, though the screen, keyboard and primary hard disk are the main items. When I say the OS, I actually mean both the bootloader that loads the OS and the OS itself once it is handed off to.
Next, the BIOS should, as soon as it has identified that the primary boot hard disks are ready, begin transferring data from the boot area into RAM. Almost all machines have far more RAM than they need to boot, and so pre-loading all blocks needed for boot into a cache, done in optimal order, will mean that by the time the OS kernal takes over, many of the disk blocks it will want to read will already be sitting in ram. Ideally, as I noted, the blocks should have been pre-stored in contiguous zones on the disk by an algorithm that watched the prior boots to see what was accessed and when.
Indeed, if there are multiple drives, the pre-loader could be configured to read from all of them, in a striping approach. Done properly, a freshly booted computer, once the drives had spun up, would start reading the few hundred megabytes of files it needs to boot from multiple drives into ram. All of this should be doable in just a few seconds on RAID style machines, where 3 disks striped can deliver 200mb/second or more of disk read performance. But even on a single drive, it should be quick. It would begin with the OS kernel and boot files, but then pre-cache all the pages from files used in typical boots. For any special new files, only a few seeks will be required after this is done. read more »

On a recent trip on a plane equipped with personal inflight video screens for each seat, I decided to watch a movie quickly and then have a nap. So I started watching the movie right after settling into the seat, about 20 minutes before takeoff. I figured with that I would watch the 1:30 minute movie through the meal service and be ready for the nap about an hour into the flight. What I learned instead was a greater awareness of just how many announcements there are on a typical flight these days. That’s because the in-flight system paused the video with each announcement and put it through my noise cancelling headphones.
The many announcements included:
- The routine ones about the process of takeoff. Door closing. Seatbelt sign on. Various blah-blah-blah
- The huge array of safety announcements and instructions I’ve seen literally hundreds of times.
- A very few useful announcements: Destination check, reasons for delay, updates on flight time.
- Some possibly useful announcements (cell phones off now, OK to use electronics now.)
- Ads: Join our frequent flyer program, get our frequent flyer card, shop from the duty free cart, buy meals, buy drinks (which did not even apply to those not in coach.)
The cacophony is getting worse, almost as bad as when you’re sitting in the terminal with the endless announcements. They know people hate that in the terminals and offer the paid lounge with no announcements, but I’ve said they should just use cell phones insteadand give us peace. On Japanese Shinkansen, they also offer a “quiet car” with no announcements — it is up to you to set your own alarm to make sure you don’t miss your stop if you want to sleep or relax. The trains are so on-time you can do this.
How about doing something like this, at least on a modern airplane where you have a personal screen for each seat? read more »

I recently went to the DLD conference in Germany, briefly to Davos during the World Economic Forum and then drove around the Alps for a few days, including a visit to an old friend in Grenoble. I have some panoramic galleries of the Alps in Winter up already.
Each trip brings some new observations and notes.
- For the first time, I got a rental car which had a USB port in it, as I’ve been wanting for years. The USB port was really part of the radio, and if you plugged a USB stick in, it would play the music on it, but for me its main use was a handy charging port without the need for a 12v adapter. As I’ve said before, let’s see this all the time, and let’s put them in a few places — up on the dashboard ledge to power a GPS, and for front and rear seats, and even the trunk. And have a plug so the computer can access the devices, or even data about the car.
- The huge network of tunnels in the alpine countries continues to amaze me, considering the staggering cost. Sadly, some seem to simply bypass towns that are pretty.
- I’ve had good luck on winter travel, but this trip reminded me why there are no crowds. The weather can curse you, and especially curse your photography, though the snow-covered landscapes are wonderful when you do get sun. Three trips to Lake Constance/Bodenzee now, and never any good weather!
- Davos was a trip. While there was a lot of security, it was far easier than say, flying in the USA. I was surprised how many people I knew at Davos. I was able to get a hotel in a village about 20 minutes away.

This weekend I spoke at BIL, a conference that was created to play off of the famous and expensive TED conference. BIL began as an un-conference, which is to say an ad-hoc conference created on short notice where the attendees are the speakers. Such conferences tend to be free or near-free. The movement begain with Tim O’Reilly’s FOO Camp. FOO camp is for Tim’s friends, and he has far more friend that can come. One year, he was explaining how he rotated among people and so some of those who were not invited that particular year (including myself) had a “BAR” camp which was a tremendous success, and created a trend.
The first two BILs were a lot of fun and worked pretty well. They had a variety of sub-par speakers, as these “anybody who wants to can talk” conferences often have, but there was always tons of hall conversation or sessions in other rooms to make up for that. And a modest number of TED speakers came over and gave their TED talks for free at BIL, and various regular TED attendees came as well.
This year’s BIL did not live up to the earlier standard, and the hard-working and generous organizers are fully aware of that, so this is not an attempt to criticise them, but rather to look at the problem. Many things went wrong, including a last minute need to move the conference from a Saturday and Sunday(with only Saturday morning overlap with TED) to Friday and Saturday morning, which had total overlap with TED and minimal weekend time. This change was forced because no venue could be found (cheaply enough, at least) which would offer Saturday afternoon and Sunday. However, it was a ruinous change — attendance on the workday Friday was way down, and even lower on Saturday, and no TED speakers came though a few attendees showed up, mostly near the end in the 2 hours after TED that BIL went on. The “outdoor” post-sessions were of limited success as a conference, but OK socially (I did not attend the planned Sunday events.) read more »

Tomorrow, I will be speaking on pre-Robocar technology at BIL an unconference that parallels the famous and expensive TED conference. This is in Long Beach, CA. Unconferences are fun, cheap and often as good as expensive conferences. I will also be attending a reception at TED tonight for Singularity University, which I lecture at, so I may see you if you’re at TED as well.
Last night’s EFF bash was a great success. Thanks to Adam Savage and all the others who made it go so well.

In early 2000, after a tumultuous period in the EFF’s history, and
the staff down to just a handful, I was elected chair of the Electronic Frontier Foundation.
I had been on the board for just a few years, but had been close to the
organization since it was founded, including participating with it as
a plaintiff in the landmark supreme court case which struck down the
Communications Decency Act in 1996.
Having now served 10 years as chairman, it is time to rotate out, and I
am happy to report the election of John Buckman, founder of Magnatune
and Bookmooch (among other ventures) as our new chair. As a part-time
resident of Europe, John will, like me, offer an international perspective
to the EFF’s efforts. Pam Samuelson, a law professor of stunning
reputation and credentials, is the vice-chair for the coming
5-year term, replacing John Perry Barlow.
I would love to claim credit for the EFF’s tremendous growth and success
during my tenure, but the truth is that our active and star-studded board
is a board of equals. We all take an active role in setting policy
and attempting to guide the organization in its mission to protect
important freedoms in the online world. While it would shock most of
my previous employees, my board management has been very laissez-faire.
I and the other board members try to let our great team do their stuff.
After I became chairman, one of the best things we on the board
did was to re-recruit Shari Steele, our former legal director,
to become the new executive director. Shari had been with the EFF for
many years but had left to work on a new venture. We brought her back
and it’s been positive ever since. We also recruited Cindy Cohn
to be our legal director. Cindy had a long history of friendship with
the organization, having worked tirelessly with our help on the fight
to stop export controls on encryption. WIth these two appointments, I
and my fellow board members started the course for an incredible decade.
In spite of a chaotic global economy, during this period, our fundraising,
budget and staff size have more than tripled. (That may seem minor
for a dot-com but it’s great news for a non-profit.) We’ve boosted
membership and membership dontations, increased funding from foundations,
and created an endowment to assure the EFF’s future.
The EFF is now 20, so I’ve been privileged to chair it for half of
its lifetime. In that period we’ve seen dramatic victories for free
speech, privacy and freedom to program. We’ve stopped e-voting abuse
and rootkits in your music CDs. We’ve protected bloggers as journalists
and preserved anonymous speech online. We’ve stopped encryption software
from being controlled like a munition and had so many other triumphs, big
and small. We’ve also seen an expanded technical and activism program,
as our technologists have led the way in unveiling things like secret
dots generated by colour laser printers that track your printouts back
to you and network interference with filesharing by cable ISPs.
We’ve also had our failures, but even those have spoken loudly about the
quality of our team. When we took Grokster/Streamcast to the supreme
court, our client lost, but the court laid down a fairly narrow standard
that allows software developers building new generations of publishing
products to know how to stay clear of liability. Our cases against the
White House’s warrantless wiretapping program have hit major hurdles,
one of which was an act of congress created specifically to nullify our
attempts to have a court examine this program — granting a retroactive
immunity to the phone companies that did it. Bad as that was, I figure
if they have to get an act of congress to stop you, you know you’ve hit
We’ve also hit many nerves with our great FOIA team that has uncovered
all sorts of attacks on your rights, and continues to do so, and our
team of activists and our new international team are working hard to
promote our doctrine of free speech and freedom to develop technology
around the world. With all our team does, many are shocked to find it is
only around 30 people. Still, we could do much more and your donations
are still what makes it all happen. I hope that if you believe in the
duty to protect fundamental freedoms online, you will work towards that end directly,
or consider outsourcing that work with a donation to us.
I am not leaving the EFF — far from it. I will continue to be
an active boardmember. In addition, I will begin to re-explore
commercial ventures, seek new opportunities, and continue on my quest
to become a leading evangelist for one of the world’s most exciting
new technologies — robotic transportation. At my robocars site you
can see my beginnings of a book on the subject, and why it may have the
largest positive effect on the world that computer technology delivers
in the medium term. Of course with my EFF hat on you will find growing
sections on the freedom and privacy issues of the technology.
During my tenure, I have served with a tremendous group of
fellow board members, as you can see from the biographies at
the EFF board page. I will continue to work with them to
protect your rights as the world becomes digital, and I hope you will all
join with me in supporting the EFF with your thoughts and your dollars.
We’ll mark the transition tonight, Feb 10 at the special EFF 20th birthday bash
at DNA lounge. This fundraiser can be attended
with a requested $30 donation, and there is also a special VIP event earlier where you can mingle more
intimately with the special guests, such as Mythbuster Adam Savage. We have quite a program planned.

I’ll have many more observations about my recent trip to DLD, Davos and the Alps soon, but one thing I’ve decided I do want to find (or train) is a travel agent/helper who can assist well with unscheduled travel (ie. a road or railpass trip.)
With unscheduled travel, you don’t know in the morning where you will end up that night. You only figure it out later in the day. Sometimes you just drive until it starts getting late and then you pick where you will end the night. It’s hard (or expensive) to do this in high season but in low season you can always find a room, and I and many others like that sort of freedom.
So when you do pick where you want to end up you have a few options:
- You can have a guidebook or database (such as AAA in the USA) and phone around places until you get something you like
- You can hunt around for web access (better if you have a data plan on your phone) and use sites like TripAdvisor and the various booking search engines (like Kayak/Sidestep) to find a decent hotel at a good price.
- You can just drive into town and look for Vacancy/Zimmer Frei signs and go in and ask the price.
- You can find somebody to do this for you.
There are problems with all these approaches. Method 3 (especially using tripadivsor) helps you avoid turkey hotels and find the better values. However, the databases cover only a fraction of the hotels, and the online reservations systems also cover only a small fraction of hotels in an area. There will be better values out there. On the other hand, many hotels offer a better price through the internet than if you call them, or will charge even more if you just walk in. read more »

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.

This weekend is the Foresight Institute conference on molecular nanotechnology and AI. I am on the board of Foresight Institute and will be speaking on the latest developments in robocars at the conference, along with a raft of great speakers. If you are interested in futurist issues around AI, nanotech and other accelerating technologies, this is the longest running conference in the field and the place to be. The whole conference is just $175 and you can register for it here.
I will also be doing my general Robocar talk on Wednesday, February 24th at the “Homebrew Robotics Club” of Silicon Valley. This is a great group of people who hack robotics as a hobby, and it meets at the CMU building at NASA Ames Research Center. This event is free and open to the public.
Finally, in 2 weeks I will be attending the DLD 10 conference in Munich Germany, and may try to make my way into some parties at the World Economic Forum in Davos while doing a little Alpine road trip after DLD.

The pharma industry is littered with cases of drugs that showed good promise, but proved to be too dangerous when they got into human trials. Dangerous side effects will cancel development for most drugs. In some cases, such as Vioxx and Fen-Phen the dangerous effects were discovered later, and the drugs pulled from the market.
Some people got better on the drugs, others had bad side effects. Sometimes those bad side effects will be the result of various environmental factors, or perhaps rarely they will be bad luck. However, I suspect that some good portion of the time, they will be due to genetic factors in the test subject.
DNA sequencing is getting cheaper every day. Even today the whole genome can be done for $5,000 wholesale and many expect it to be hundreds before long. Collections of 600,000 to 1,000,000 SNPs can be read for a few hundred dollars.
It strikes me that the drug companies will want to make efforts immediately to get DNA samples, if they don’t have them, from all the people who participated in the trials of failed drugs, particularly those who had the bad side effects. And to get those samples sequenced. Because in some cases, they may well find a connection between the bad reaction and genetic patterns. They might find cases where all the side effects had one gene and all the regular reactions had another.
If they do find this, then suddenly they will have a billion dollar drug on their hands again, with much of the work already done, presuming the FDA and other regulatory agencies accept this approach. With the gene identified, making a test for it would be very cheap, and suddenly a useful drug might be available to those who have no problems with it. This might leave the people with the reacting DNA out in the lurch of course, and nobody is likely to try to find a drug for them in the immediate future.
If people get large DNA scans, those scans should remain in the possession of the patient or their doctor. There are already laws forbidding insurance companies in some jurisdictions from using DNA data to adjust insurance, but there will be powerful forces trying to reverse this.
DNA results will also explain differing efficacies of the drugs. It’s already been learned that many people need different doses of the same drug, and also that some drugs
work on men but not on women, for example.
I expect this will be standard practice for future drug trials, but my point today is that since many of these people are still alive, we can reach into the past and learn the truth about long-past drug trials as well, and perhaps get a brief flood of new useful substances as long as the patient is DNA typed in advance.

I was contacted this week by the daughter of Don Watt, a well known Canadian graphic designer responsible for the branding and logos at many large companies including Loblaws and WalMart. Watt had just died at the end of December, and she was looking for more information from me about her father’s account of how he had secretly been the designer of the modern Canadian Flag. She contacted me, because in his story, my father, Charles Templeton, had been the go-between for Watt and the government leaders who picked the flag.
There’s a bit about Watt’s story in this Toronto Star Obituary for him. His version contradicts the official version quite markedly, and there is evidence on both sides. Many of the players, however, are deceased.
As the story goes, there was a plan to give Canada its own flag, replacing the colonial Red Ensign. A national contest was held, and people could submit designs. Don Watt worked at Hathaway-Templeton, a design firm co-founded by my uncle Bill Templeton in Toronto. My father was also working at Hathaway-Templeton at the time — his brother gave him a job to help him recover from his expensive 2nd place run for leader of the Ontario Liberal Party. (Or this may have been just before he worked there, during his various visits to his brother’s company.)
Watt came up with a flag design, supposedly like the current one but with blue bars (“From sea to sea” being the motto.) He says he did this because my father told him the government didn’t like the designs that were coming in through the competition. Watt did a design and my father took it to the leadership in Ottawa — the Liberal party was in power at the time under Prime Minister “Mike” Pearson, and they were the ones driving the controversial flag change. In one version of the story Pearson likes the design but prefers red bars (the Liberal party colours after all, but also the national colours.) Contradictory reports say Pearson liked an alternate design with blue bars but 3 maple leaves in the middle.
According to Watt, when his flag was chosen, it was also felt it would be bad if it were known that the design came from a professional logo designer, and worse, from one working for a design firm with many government contracts and tied to a prominent person in the Liberal party (ie. my father.) This was very far from the impression they had of a populist contest.
So it was, according to Watt, agreed that his role and my father’s would be kept silent. Many others had similar designs, bars and maple leaves in various sizes and configurations were common in many of them. Other names got the glory, but Watt was content with that.
Watt told his family, and later after the secrecy period was over, others in the industry but never made big public declarations about it. He told it to my cousin with whom he worked closely.
Is the story true? It’s hard to evaluate. The others did have similar designs, and even if Watt’s version is correct, I suspect they honestly believe it was their designs that were used. And of course, it may be true. From what little I know of Mr. Watt, he seems to have a good reputation and many other claims to fame, so it does not seem the sort of story he would need to make up.
However, my prime reason for some skepticism comes from the fact that my father never told me this story, nor put it in his memoirs. He wasn’t the sort of person to avoid bragging. If the story is true and he never told of it, he must have had a particularly strong sense of honour on the temporary bond of secrecy, and did not want to disrupt the official story. Nor did Watt until his later years.
Still, it was an interesting anecdote to hear. The Canadian experience is different from the U.S. one. Things like the Candian flag and
constitution are events in living memory, while for the USA, they are distant history. If true, it would be a fun thing to add to the list of family stories.
On a side note, the Canadian flag is considered one of the better ones from a graphic design standpoint by some.

Everybody has an Avatar review. Indeed, Avatar is a monument of moviemaking in terms of the quality of its animation and 3-D. Its most interesting message for Hollywood may be “soon actors will no longer need to look pretty.” Once the generation of human forms passes through the famous uncanny valley there will be many movies made with human characters where you never see their real faces. That means the actors can be hired based strictly on their ability to act, and their bankability, not necessarily their looks, or more to the point their age. Old actors will be able to play their young selves before too long, and be romantic leading men and women again. Fat actors will play thin, supernaturally beautiful leads.
And our images of what a good looking person looks like will get even more bizarre. We’ll probably get past the age thing, with software to make old star look like young star, before we break through the rest of the uncanny valley. If old star keeps him or herself in shape, the skin, hair and shapes of things like the nose and earlobes can be fixed, perhaps even today.
But this is not what I want to speak about. What I do want to speak about involves Avatar spoilers. read more »

Who writes a gift guide in January?
This one is not about specific gifts but rather a philosophy of gift giving. Every year at Seasons I run into the problem that decently well off adults have with gift giving. They will often ask for a list of possible gifts, not knowing what to get. And it can be hard to come up with the list because, frankly in these days of online ordering, if there’s something you really want that is not that expensive an item, you would have bought it already.
I believe that instead of giving people what they want, you should give them what you want to give them. This is not simply a desire to make gift giving more selfish, to making giving be in the interests of the giver. It is a statement that a proper gift should be an expression of yourself. It should be something you enjoy giving, and not just because you want to bring a smile to your recipient (though you should also want that.)
Christmas shoppers often overspend to buy fancy and overadvertised gifts which seem nice but which are never really used by the recipient. This is actually a major inefficiency in the economy, in that products are produced to little productive end other than to say, “see, I spent some serious money on you.” We’ll never stop that but we might redirect it.
Rule One: No money between adults
Adults should never give money. That’s not an expression of yourself, unless the expression is “I’m really rich.” The one exception is that parents can give life-changing amounts of money to children. A large sum can be an expression of your instinctive desire to make your kids’ lives better. Likewise employers can give cash bonuses. But those are not really gifts.
Rule One-A: Absolutely no gift cards.
Gift cards are like giving money, except they’re stupid money that can only be spent at one store. Stores love them because people leave $5 billion undredeemed on gift cards every year — down from $10 billion back when they were allowed to let gift cards expire. Many people think a gift card is better than money because it says, “OK, at least I know enough about you to get you a gift card at a store I know you like to shop at.” But that’s hardly saying much.
Gift cards from generic stores that sell something for everyone are right out. That’s just the gift of cash with a restriction. Gift cards might be more tolerable from extreme specialty stores, so that your picking of the store constitutes an expression of yourself and your relationship with the recipient.
Gift cards for services are a bit more tolerable. After all, it’s hard to give services otherwise.
Gift cards would make more sense if they were offered at a discount, so you could buy a $50 card usable after seasons for $40. They almost never do this though. But it still isn’t much of an expression of you.
Exception: If you truly need a gift that requires no expression of yourself, these might work. For example, gifts for people you don’t know well, gifts for a large group of co-workers etc. But what you’re saying here is, “listen, I wanted to give you a small gift but let’s face it, you weren’t high enough up on the list to merit a lot of time.”
Sometimes that’s a perfectly OK thing to say, if it’s a gift for your postal worker or the office.
Limit your manufactured items
The adage that the best gifts are ones you make yourself has much truth. And where you can afford the time for that, or have the skills for it, this is indeed the right way to go. But I don’t expect you to stop giving manufactured items entirely.
When you give a manufactured item, one that you can just point-click-and-ship, the gift is not the item, but what went into selecting it. The choice must depend not on your impressions of what they want, but rather ways in which you can be better (by some standards) at picking what they want than they are. You must find something that you knew was good but they didn’t.
So if you really know cameras, you probably know better how to shop for certain items. Buy something that you know more about than the recipient. Do you have good taste in clothing, or know where the best shops are? That’s where to buy your items. Not in a big box store or at the mall — anybody can go there.
Do you own and love a hot gadget that is not that popular yet? Get it, even though they might not love it as much. What you are sharing is your knowledge and love for the item, to let them see and experience a part of your life.
Books and other media
One particular type of manufactured item deserves special attention, namely books and media. Don’t give books of the type they like to read. Give the books and authors that you have read and love. Again, you might give them a book they would not love as much as the new hardcover from their favourite author. But the book, and the love for it, is an expression of you. If you know them intimately enough to know of books by their favourite writers which they themselves might not know about, that’s also OK.
It’s also OK if you are a better researcher to use that skill to surprise them. Perhaps you know more about how to look things up online, or read the right blogs where good people will recommend things. You can buy those things as long as your knowledge was special, and not generic.
Time rather than money
No gift expresses yourself more than time. A gift which is hard to choose and takes time says more than a gift which cost a lot. Most personalization requires time. Photography can be a great source for this — do you have a series of photos of the person, or places they love, that you could make into a slideshow or poster?
In addition, we all have too much stuff already, so don’t just give more “stuff” that they have to bring out when you visit. Unless they have a weight problem or a drinking problem, unusual foods and drinks that you enjoy can be a good expression of yourself. Of course, stuff you made yourself is even better.
Sometimes ya gotta break the rules
This is not the only way to give gifts. And nobody will figure the perfect gift for every person every time, not even close. This is just a direction to go, in opposition to what is most marketed — “impress them with how much money you were willing to spend on them.” And while your gift should be an expression of your personality, it would be wrong to think this means that gift giving is all about you, the giver. Rather the message is that it’s about both people.
In addition, many of these rules don’t apply to gifts to young children. First of all young children may not yet be able to understand an adult’s expression. And unlike adults they don’t have all that they want. They are easy to impress and very grateful.
Still, which children, look to gifts that you particularly enjoyed as a child, or in particular gifts which changed your life in a positive way. Did a football turn you into an athlete? Did a microscope make you a scientist? Pass it on.

I have the photo archives of a theatre company I was involved with for 12 years. It is coming upon its 50th anniversary. I have a high speed automatic scanner, so I am going to generate scans of many of the photos — that part is not too hard.
Even easier for modern groups in the digital age, where the photos are already digital and date-tagged.
But now I want members of the group to be able to rotate the photos, tag them with the names of people in them and other tags, group them into folders where needed, and add comments. I can’t do this on my own, it is a collaborative project.
Lots of photo sharing sites let other people add comments. Few sites let you add tags or let trusted other people do things like rotations. Flickr lets others draw annotations and add tags/people which would make it a likely choice, but they can’t rotate.
Facebook has an interesting set of features. It’s easy to tag photos with friends’ names, and they get notified of it and the photos appear on their page, which is both good and bad. (The need for the owner to approve is a burden here.) Tagging non-friends is annoying because when somebody adds a real friend tag you must delete the old one, and the old ones may be spelled differently. However, the real deal-breaker on facebook is that the resolution is unacceptably small.
The recent killer feature I really want is face recognition, which makes tagging with people’s names vastly easier. Even the fact that it auto-draws boxes around the faces for you to tag is a win even without the recognition feature. The algorithms are far from perfect but they speed up the task a great deal. As such, right now an obvious choice is Picasa and Picasa Web Albums. however, while PWA lets you allow others to upload photos to your albums and tag their own photos, they can’t tag yours.
There is also face recognition in iPhoto, but I am not a Mac user so I don’t know if that can meet this need.
So right now two choices seem to be Flickr (but I must do all rotates) or a newly created Picasa account to which the password is shared. That’s a bit of a kludge but it seems to be the only way to get shared face recognition tagging.
Facebook can be integrated with a face recognizer called “Polar Rose” which also works with the 23hq photo sharing site. However, Facebook’s resolution is way, way too small and you need to approve tags.
I have not tried all the photo sharing sites so I wonder if people know of one that can do what I want?

I just landed on a flight from Toronto to San Francisco. If you were inside the USA you may not have heard about the various crazy rules applied to travel to the USA, or at least not experienced them. While we were away the rules changed every day, and perhaps every hour.
Toronto was hit the hardest because it has the most flights to the USA of any airport in the world (with a few other Canadian airports not far behind.) Due to the busy border, you clear U.S. customs and immigration through their satellite office in Toronto, so your plane lands you at domestic gates in the USA, making connections far easier.
The USA started insisting on intimate pat-downs on all passengers and complete hand screening of all carry-ons. For a while there was even a regulation that passengers would have to sit in their seats with nothing on their laps (not blankets, not books, not computers) for the last hour of the flight. That got reverted to “pilot’s discretion” and in our case there was no talk of this.
The heavy search requirements brought Toronto’s heavy to-USA traffic to a standstill. Even with extra mounties pitching in, there was now way to get all those people through the terminal, so the CATSA brought in a near-ban on carry-ons. You could only carry on items from a short list. Notable things not on the list (ie. banned) included books, kid’s toys, lenses and various items people bring on not because they need them in flight, but because they are essential to their trip, or are fragile.
After a few days of reduced carry-ons, they got the processing down, as long as you got there 3 hours in advance, sometimes more. A real burden on 1 hour flights to New York, Boston or Washington. Still a burden on my 5 hour flight to SFO, since that was at 7am, meaning getting to the airport at 4am, (1am Pacific Time, about the time I would get to bed.)
The process included the fairly standard x-ray (with agents making various exceptions for people, generally allowing books that could be paged through and even some small knapsacks) with pat down only if you set off the alarm. Then, shortly after you started walking down the row of gates was a 2nd checkpoint. There you got a serious patdown that might remind you of a massage, and a complete hand inspection of everything in your bags. (I suggest they should let you pay extra for a real massage, which also of course detects anything on your body.) Many checks of ID and boarding pass and you are on your way.
There are many disturbing things about the reaction to the underpants bomber but a few stand out.
- It is certain that the TSA and all other major agencies knew about the risk of somebody strapping explosives to their legs and taking them through the magnetometer. So a plan should have been in place long ago about what to do about it, and how to react at the first public incident.
- In spite of this the agencies are out running around like chickens with their heads cut off, changing plans every day, no sign of forethought. Are they just testing the public to see what they will tolerate?
- Lots of talk of thz scanners to see everybody naked. Is this a way to get those accepted, after people complained?
- For Toronto, and most of the Canadian airports, a bad guy can quite readily drive just 90 minutes and go to another airport like Buffalo and get no special screening! While the public does not like this extra trek, it’s no burden to the terrorist to do this. Only the innocent are punished.
- You could still smuggle your stuff inside a laptop, or a body cavity or several other places I noticed.
- Keep this up and people will stop flying, and they will definitely go to airports like Buffalo.
- As I have suggested before, appointments for security inspections are one answer to the 3 hour early arrival.
- For me the worst thing was packing lenses in checked bag. I had to improvise protection for them. When such a rule is put in place by surprise over Christmas, you have to expect a lot of people brought stuff that they needed to carry on on the way back, even if they would not plan a new trip today expecting to carry on their fragiles.
With some irony, all this came after a lunch with Peter Watts. If you didn’t hear, Peter was crossing back into Canada at Port Huron/Sarnia and got pull over for exit inspection leaving the USA. Because he wasn’t a complete little sheep, he reports he was beaten up by the border patrol and now is charged with assaulting an officer. I really doubt he did those things, but the most disturbing thing are those who comment on the story saying it’s his fault for not being subservient enough. I understand the reasons for letting police do their jobs, but when you are just inspecting people driving out of the country, with no special reason to believe they are criminals or worthy of above average suspicion or anything but the presumption of innocence we are all owed, then there should be standards, and better defined rights for the subject of the inspections. If a person is not a known threat, why should they not get to ask questions about what is being done to them and their vehicle? Yes, one time in many thousands, an actual nasty criminal might do something odd and need to be set upon with force. It’s one of the risks people take doing an armed policing job. It can happen anywhere, any time. But must the people give up their rights and be complete sheep because of it?
Can’t we have a system where different situations suggest different levels of police control? Where the police, while they may have the power to give you orders and you have to obey without much chance to question, get in trouble if they abuse that power in a non-hostile situation? Where they have a simple way of explaining that they think the situation has escalated, and a way to declare it that we are taught in school to understand? So if the copy says, “I’m escalation — get on the ground now” you have to get on the ground, but the cop has to justify later why he escalated. Simply being a citizen who is mindful of his rights doesn’t seem much grounds for that.

I’ve been feeling we in the secular, atheist world should still have an official event at the end of the year, since with the Christians and the Jews making merry, it’s a good time to do it. We have New Year’s Eve of course, but so does everybody.
This new holiday, to mark the changing of the Seasons might be called “Seasons.” Of course that is in part so that all the people saying “Seasons Greetings” (without the apostrophe, oddly enough) will now be making our greeting. Another name for it could be “Holidays” but that does have religious roots.
Now the real changing of the seasons is around Dec 21, but it makes far more sense to celebrate a gift holiday on Dec 28-29. That way you can buy gifts for everybody at half price. And we seculars are smart and thrifty.
So Happy Seasons to all.

I’m waiting for the right price point on a good >24” monitor with a narrow bezel to drop low enough that I can buy 4 or 5 of them to make a panoramic display wall without the gaps being too large.
However, another idea that I think would be very cool would be to exploit the gaps between the monitors to create a simulated set of windows in a wall looking out onto a scene. It’s been done before in lab experiments with single monitors, but not as a large panoramic installation or something long term from what I understand. The value in the multi display approach is that now the gap between displays is a feature rather than a problem, and viewers can see the whole picture by moving. (Video walls must edit out the seams from the picture, removing the wonderful seamlessness of a good panorama.) We restore the seamlessness in the temporal dimension.
To do this, it would be necessary to track the exact location of the eyes of the single viewer. This would only work for one person. From the position of the eyes (in all 3 dimensions) and the monitors the graphics card would then project the panoramic image on the monitors as though they were windows in a wall. As the viewer’s head moved, the image would move the other way. As the viewer approached the wall (to a point) the images would expand and move, and likewise shrink when moving away. Fortunately this sort of real time 3-D projection is just what modern GPUs are good at.
The monitors could be close together, like window panes with bars between them, or further apart like independent windows. Now the size of the bezels is not important.
For extra credit, the panoramic scene could be shot on layers, so it has a foreground and background, and these could be moved independently. To do this is would be necessary to shoot the panorama from spots along a line and both isolate foreground and background (using parallax, focus and hand editing) and also merge the backgrounds from the shots so that the background pixels behind the foreground ones are combined from the left and right shots. This is known as “background subtraction” and there has been quite a lot of work in this area. I’m less certain over what range this would look good. You might want to shoot above and below to get as much of the hidden background as possible in that layer. Of course having several layers is even better.
The next challenge is to very quickly spot the viewer’s head. One easy approach that has been done, at least with single screens, is to give the viewer a special hat or glasses with easily identified coloured dots or LEDs. It would be much nicer if we could do face detection as quickly as possible to identify an unadorned person. Chips that do this for video cameras are becoming common, the key issue is whether the detection can be done with very low latency — I think 10 milliseconds (100hz) would be a likely goal. The use of cameras lets the system work for anybody who walks in the room, and quickly switch among people to give them turns. A camera on the wall plus one above would work easily, two cameras on the left and right sides of the wall should also be able to get position fairly quickly.
Even better would be doing it with one camera. With one camera, one can still get a distance to the subject (with less resolution) by examining changes in the size of features on the head or body. However, that only provides relative distance, for example you can tell if the viewer got 20% closer but not where they started from. You would have to guess that distance, or learn it from other queues (such as a known sized object like the hat) or even have the viewer begin the process by standing on a specific spot. This could also be a good way to initiate the process, especially for a group of people coming to view the illusion. Stand still in the spot for 5 seconds until it beeps or flashes, and then start moving around.
If the face can be detected with high accuracy and quickly, a decent illusion should be possible. I was inspired by this clever simulated 3-D videoconferencing system which simulates 3-D in this way and watches the face of the viewer.
You need high resolution photos for this, as only a subset of the image appears in the “windows” at any given time, particularly when standing away from the windows. It could be possible to let the viewer get reasonably close to the “window” if you have a gigapan style panorama, though a physical barrier (even symbolic) to stop people from getting so close that the illusion breaks would be a good idea.

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.
