Ever since the first science fiction about cyberspace (First seen in Clarke’s 1956 “The City and the Stars” and more fully in 1976’s “Doctor Who: The Deadly Assassin”) people have wanted to build online 3-D virtual worlds. Snow Crash gelled it even further for people. 3D worlds have done well in games, including Mmorpgs and recently Second Life has attracted a lot of attention, first for its interesting world and its even more interesting economy, but lately for some of the ways it has not succeeded, such as a site for corporate sponsored stores.
Let me present one take on why 3D is not all it’s cracked up to be. Our real world is 3D of course, but we don’t view it that way. We take it in via our 2D eyes, and our 1.5D ears and then build a model of its 3D elements good enough to work in it. In a way I will call this 2.5D because it’s more than 2D but less than 3. But because we start in two dimensions, and use 2D screens, 3D interfaces on a flat screen are actually worse than ones designed for 2D. Anybody who tired the original VRML experiments that attempted to build site navigation in 3D, where you had to turn around your virtual body in order to use one thing or another, realized that.
Now it turns out the fact that 3D is harder is a good thing when it comes to games. Games are supposed to be a challenge. It’s good that you can’t see everything and can get confused. It’s good that you can sneak up behind your enemy, unseen, and shoot him. Because it makes the game harder to win, 3D works in games.
But for non-games, including second life, 3D can just plain make it harder. We have a much easier time with interfaces that are logical, not physical, and present all the information we need to use the system in one screen we can always see. The idea that important things can be “behind us” makes little sense in a computer environment. And that’s true for social settings. When you sit in a room of people and talk, it’s a bug that some people are behind you and some are in front of you. You want to see everybody, and have everybody see your face, the way the speaker on a podium would. The real 3D world can’t do that for a group of people, but virtual worlds can.
I am not saying 3D can’t have its place. You want and need it for modeling things form the real world, as in CAD/CAM. 3D can be a place to show off certain things, and of course a place to play games.
In making second life, a better choice might have been a 2D interface that has portals to occasional 3D environments for when those environments make sense. That would let those who want to build 3D objects in the environment get the ability to do so. But this would not have been nearly as sexy or as Snow-Crashy, so they didn’t do it. Indeed, it would look too much like an incremental improvement over the web, and that might not have gotten the same excitement, even if it’s the right thing to do. The web is also 2.5D, a series of 2D web pages with an arbitrary network of connections between them that exists in slightly more than 2 dimensions. And it has its 3D enclaves, though they are rare and mostly hard to use.
Another idea for a VR world might be a 3D world with 360 degree vision. You could walk around it but you could always see everything, laid out as a panorama. You would not have to turn, just point where you wish to go. It might be confusing at first but I think that could be worth experimenting with.

It’s way late, but I finally put captions on my gallery of regular-aspect photos from Burning Man 2006.
Some time ago I put together the 2006 Panoramas but just never got around to doing the regulars. There are many fun ones here, an particular novel are the ones of the burn taken from above it on
I also did another aerial survey, but that remains unfinished. Way too much processing to do, and Google did a decent one in google maps. I did put up a few such photos there.

Earlier I wrote about the frenzy buying Plastation 3s on eBay and lessons from it. There’s a smaller scale frenzy going on now about the iPhone, which doesn’t go on sale until 6pm today. With the PS3, many stores pre-sold them, and others lined up. In theory Apple/AT&T are not pre-selling, and limiting people to 2 units, though many eBay sellers are claiming otherwise.
The going price for people who claim they have one, either for some unstated reason, or because they are first in line at some store, is about $1100, almost twice the cost. A tidy profit for those who wait in line, time their auction well and have a good enough eBay reputation to get people to believe them. Quite a number of such auctions have closed at such prices with “buy it now.” If you live in a town without a frenzy and line it might do you well to go down to pick up two iPods. Bring your laptop with wireless access to update your eBay auction. None of the auctions I have seen have gone so far as to show a picture of the seller waiting in line to prove it.
eBay has put down some hard terms on iPhone sellers and pre-sellers. It says it does not allow pre-sales, but seems to be allowing those sellers who claim they can guarantee a phone. It requires a picture of the actual item in hand, with a non-photoshopped sign in the picture with the seller’s eBay name. A number of items show a stock photo with an obviously photoshopped tag. In spite of the publicised limit of 2, a number of people claim they have 4 or more.
It seems Apple may have deliberately tried to discourage this by releasing at 6pm on Friday, too late to get to Fedex in most places. Thus all most sellers can offer is getting the phone Monday, which is much less appealing, since that leaves a long window to learn that there are plenty more available Monday, and loses the all-important bragging rights of having an iPhone at weekend social events. Had they released it just a few hours earlier, I think sales like this would have been far more lucrative. (While Apple would not want to leave money on the table, it’s possible high eBay prices would add to the hype and be in their interest.)
As before, I predict timing of auctions will be very important. At this point even a 1 day auction will close after 18 hours of iPhone sales, adding a lot of rish. The PS3 kept its high value for much of the Christmas season, but the iPhone, if not undersupplied, may drop to retail in as little as a day. A standard 1 week auction would be a big mistake. Frankly I think paying $1200 (or a $300 wait-in-line fee) is pretty silly.
The iPhone, by the way, seems like a cool generalized device. A handheld that has the basic I/O tools including GSM phone and is otherwise completely made of touchscreen seems a good general device for the future. Better with a small bluetooth keyboard. Whether this device will be “the one” remains to be seen, of course.

Last week I talked briefly about self-driving delivery vehicles. I’ve become interested in what I’ll call the “roadmap” (pun intended) for the adoption of self-driving cars. Just how do we get there from here, taking the technology as a given? I’ve seen and thought of many proposals, and been ignoring the one that should stare us in the face — delivery. I say that because this is the application the DARPA grand challenge is actually aimed at. They want to move cargo without risks to soldiers. We mostly think of that as a path to the tech that will move people, but it may be the pathway.
Robot delivery vehicles have one giant advantage. They don’t have to be designed for passenger safety, and you don’t have to worry about that when trying to convince people to let them on the road. They also don’t care nearly as much about how fast they get there. Instead what we care about is whether they might hit people, cars or things, or get in the way of cars. If they hit things or hurt their cargo, that’s usually just an insurance matter. In fact, in most cases even if they hit cars, or cars hit them, that will just be an insurance matter.
A non-military cargo robot can be light and simple. It doesn’t need crumple zones or airbags. It might look more like a small electric trike, on bicycle wheels. (Indeed, the Blue Team has put a focus on making it work on 2 wheels, which could be even better.) It would be electric (able to drive itself to charging stations as needed) and mechanically, very cheap.
The first step will be to convince people they can’t hit pedestrians. To do that, the creators will need to make an urban test track and fill it with swarms of the robots, and demonstrate that they can walk out into the swarm with no danger. Indeed, like a school of fish, it should be close to impossible to touch one even if you try. Likewise, skeptics should be able to get onto bicycles, motorcycles, cars and hummers and drive right through the schools of robots, unable to hit one if they try. After doing that for half an hour and getting tired, doubters will be ready to accept them on the roads. read more »

For many of us, E-mail has become our most fundamental tool. It is not just the way we communicate with friends and colleagues, it is the way that a large chunk of the tasks on our “to do” lists and calendars arrive. Of course, many E-mail programs like Outlook come integrated with a calendar program and a to-do list, but the integration is marginal at best. (Integration with the contact manager/address book is usually the top priority.)
If you’re like me you have a nasty habit. You leave messages in your inbox that you need to deal with if you can’t resolve them with a quick reply when you read them. And then those messages often drift down in the box, off the first screen. As a result, they are dealt with much later or not at all. With luck the person mails you again to remind you of the pending task.
There are many time management systems and philosophies out there, of course. A common theme is to manage your to-do list and calendar well, and to understand what you will do and not do, and when you will do it if not right away.
I think it’s time to integrate our time management concepts with our E-mail. To realize that a large number of emails or threads are also a task, and should be bound together with the time manager’s concept of a task.
For example, one way to “file” an E-mail would be to the calendar or a day oriented to-do list. You might take an E-mail and say, “I need 20 minutes to do this by Friday” or “I’ll do this after my meeting with the boss tomorrow.” The task would be tied to the E-mail. Most often, the tasks would not be tied to a specific time the way calendar entries are, but would just be given a rough block of time within a rough window of hours or days.
It would be useful to add these “when to do it” attributes to E-mails, because now delegating a task to somebody else can be as simple as forwarding the E-mail-message-as-task to them.
In fact, because, as I have noted, I like calendars with free-form input (ie. saying “Lunch with Peter 1pm tomorrow” and having the calender understand exactly what to do with it) it makes sense to consider the E-mail window as a primary means of input to the calendar. For example, one might add calendar entries by emailing them to a special address that is processed by the calendar. (That’s a useful idea for any calendar, even one not tied at all to the E-mail program.)
One should also be able to assign tasks to places (a concept from the “Getting Things Done” book I have had recommended to me.) In this case, items that will be done when one is shopping, or going out to a specific meeting, could be synced or sent appropriately to one’s mobile device, but all with the E-mail metaphor.
Because there are different philosophies of time management, all with their fans, one monolithic e-mail/time/calendar/todo program may not be the perfect answer. A plug-in architecture that lets time managers integrate nicely with E-mail could be a better way to do it.
Some of these concepts apply to the shared calendar concepts I wrote about last month.

I wrote recently about the paradox of identity management and how the easier it is to offer information, the more often it will be exchanged.
To address some of these issues, let me propose something different: The creation of an infrastructure that allows people to generate secure (effectively anonymous) pseudonyms in a manner that each person can have at most one such ID. (There would be various classes of these IDs, so people could have many IDs, but only one of each class.) I’ll call this a QID (the Q “standing” for “unique.”)
The value of a unique ID is strong — it allows one to associate a reputation with the ID. Because you can only get one QID, you are motivated to carefully protect the reputation associated with it, just as you are motivated to protect the reputation on your “real” identity. With most anonymous systems, if you develop a negative reputation, you can simply discard the bad ID and get a new one which has no reputation. That’s annoying but better than using a negative ID. (Nobody on eBay keeps an account that gets a truly negative reputation. An account is abandoned as soon as the reputation seems worse than an empty reputation.) In effect, anonymous IDs let you demonstrate a good reputation. Unique IDs let you demonstrate you don’t have a negative reputation. In some cases systems try to stop this by making it cost money or effort to generate a new ID, but it’s a hard problem. Anti-spam efforts don’t really care about who you are, they just want to know that if they ban you for being a spammer, you stay banned. (For this reason many anti-spam crusaders currently desire identification of all mailers, often with an identity tied to a real world ID.)
I propose this because many web sites and services which demand accounts really don’t care who you are or what your E-mail address is. In many cases they care about much simpler things — such as whether you are creating a raft of different accounts to appear as more than one person, or whether you will suffer negative consequences for negative actions. To solve these problems there is no need to provide personal information to use such systems. read more »

In 2005, John Scalzi burst on the scene with a remarkable first novel, Old Man’s War. It got nominated for a Hugo and won him the Campbell award for best new writer. Many felt it was the sort of novel Heinlein might be writing today. That might be too high a praise, but it’s close. The third book in this trilogy has just come out, so it was time to review the set.
It’s hard to review the book without some spoilers, and impossible for me to review the latter two books without spoiling the first, but I’ll warn you when that’s going to happen.
OMW tells the story of John Perry, a 75 year old man living on an Earth only a bit more advanced than our own, but it’s hundreds of years in the future. Earth people know they’re part of a collection of human colonies which does battle with nasty aliens, but they are kept in the dark about the realities. People in the third world are offered o ne way trips to join colonies. People in the 1st world can, when they turn 75, sign up for the colonial military, again a one-way trip. It’s not a hard choice to make since everybody presumes the military will make them young again, and the alternative is ordinary death by old age.
The protagonist and his wife sign up, but she dies before the enlistment date, so he goes on his own. The first half of the book depicts his learning the reality of the colonial union, and boot camp, and the latter half outlines his experiences fighting against various nasty aliens.
It’s a highly recommended read. If you loved Starship Troopers or The Forever War this is your kind of book.
Now I’ll go into some minor spoilers. read more »

Since the dawn of the web, there has been a call for a “single sign-on”
facility. The web consists of millions of independently operated web sites,
many of which ask users to create “accounts” and sign-on to use the site.
This is frustrating to users.
Today the general single sign-on concept has morphed into what is now called
“digital identity management” and is considerably more complex. The most recent
project of excitement is OpenID which is a standard which allows users
to log on using an identifier which can be the URL of an identity service,
possibly even one they run themselves.
Many people view OpenID as positive for privacy because of what came before it.
The first major single sign-on project was Microsoft Passport which came
under criticism both because all your data was managed by a single company and
that single company was a fairly notorious monopoly. To counter that, the
Liberty Alliance project was brewed by Sun, AOL and many other companies,
offering a system not run by any single company. OpenID is simpler and even
However, I feel many of the actors in this space are not considering an inherent
paradox that surrounds the entire field of identity management. On the
surface, privacy-conscious identity management puts control over who gets
identity information in the hands of the user. You decide who to give identity
info to, and when. Ideally, you can even revoke access, and push for minimal
disclosure. Kim Cameron summarized a set of laws of identity
outlining many of these principles.
In spite of these laws one of the goals of most identity management
systems has been ease of use. And who, on the surface, can argue with ease
of use? Managing individual accounts at a thousand web sites is hard.
Creating new accounts for every new web site is hard. We want something
However, here is the contradiction. If you make something easy to do,
it will be done more often. It’s hard to see how this can’t be true.
The easier it is to give somebody ID information, the more often it will
be done. And the easier it is to give ID information, the more palatable
it is to ask for, or demand it. read more »

In the 1980s, my brother Ty Templeton published his first independent comic book series, Stig’s Inferno. He went on to considerable fame writing and drawing comics for Marvel, D.C. and many others, including favourite characters like Superman, Batman and Spider-Man, as well as a lot of comics associated with TV shows like The Simpsons and Ren and Stimpy. But he’s still at his best doing original stuff.
You may not know it, but years ago I got most of Stig’s Inferno up on the web. Just this week however, a fan scanned in the final issue and I have converted it into web pages. The fan also scanned the covers and supplemental stories from the issues, they will be put up later.
So if you already enjoyed the other episodes journey now to Stig’s Inferno #7.
If you never looked go to The main Stig’s Inferno page. You can also check out small versions of all the issue covers.
I’ll announce when the supplemental stories are added.
The comic tells a variation of Dante’s Inferno, where our hero Stig is killed by the creatures that live in his piano and makes a strange journey through the netherworld. It’s funny stuff, and I’m not just saying it because he’s my brother. Give it a read.

First, let me introduce a new blog topic, Sysadmin where I will cover computer system administration and OS design issues, notably in Linux and related systems.
My goal is to reduce the nightmare that is system administration and upgrading.
One step that goes partway in my plan would be a special software system that would build for a user a specialized operating system “package” or set of packages. This magic package would, when applied to a virgin distribution of the operating system, convert it into the customized form that the user likes.
The program would work from a modified system, and a copy of a map (with timestamps and hashes) of the original virgin OS from which the user began. First, it would note what packages the user had installed, and declare dependencies for these packages. Thus, installing this magic package would cause the installation of all the packages the user likes, and all that they depend on.
In order to do this well, it would try to determine which packages the user actually used (with access or file change times) and perhaps consider making two different dependency setups — one for the core packages that are frequently used, and another for packages that were probably just tried and never used. A GUI to help users sort packages into those classes would be handy. It must also determine that those packages are still available, dealing with potential conflicts and name change concerns. Right now, most package managers insist that all dependencies be available or they will abort the entire install. To get around this, many of the packages might well be listed as “recommended” rather than required, or options to allow install of the package with missing 1st level (but not 2nd level) dependencies would be used. read more »

Self-driving cars are still some ways in the future, but there are some things they will want that human drivers can also make use of.
I think it would be nice if the urban data networks were to broadcast the upcoming schedule for traffic light changes in systems with synchronized traffic lights. Information like “The light at location X will go green westbound at 3:42:15.3, amber at 3:42.45.6 and red at 3:42.47.8” and so on. Data for all directions and for turn arrow lights etc. This could be broadcast on data networks, or actually even in modulations of the light from the LEDs in the traffic lights themselves (though you could not see that around turns and over hills.)
Now a simple device that could go in the car could be a heads-up-display (perhaps even just an audio tone) that tells you whether you are in the “zone” for a green light. As you move through the flow, if you started getting so fast that you would get to the intersection too early for it to be green, it could show you in the too-fast zone with a blinking light or a tone that rises in pitch the faster you are. A green light (no tone) would appear when you were in the zone.
It would arrange for you to arrive at the light after it had been green for a second or two, to avoid the risk of hitting cars running the red light in the other direction. Sometimes when I drive down a street with timed lights I will find myself trusting the timing a bit too much, so I am blowing through the moment the light is green, which actually is a bit risky because of red light runners.
(Perhaps the city puts in a longer all-red gap on such lights to deal with this?)
More controversial is the other direction, a tone telling you that you will need to speed up to catch this green before it goes amber. This might encourage people to drive recklessly fast and might be a harder product to legally sell. Though perhaps it could tell you that if you sped up to the limit you would make the light but stop telling you after no legal speed can make it. Of course, people would learn to figure it out.
We figure that out already of course. Many walk/don’t walk signs now have red light countdown timers, and how many of us have not sped up upon seeing the counter getting low? Perhaps this isn’t that dangerous. Just squeaking through a light rarely helps, of course, because the way the timing works you usually are even more likely to miss the next one, and you have to go even faster to make it — to the point that even a daredevil won’t try.
This simple device could be just the start of it. Knowledge of this data for the city (combined with a good GPS map system of course) could advise you of good alternate routes where you will get better traffic light timing. It could advise you to turn if you’re first at a red light (which it will know thanks to GPS) if your destination is off to the right anwyay. Of course it could do better combined with real traffic data and information on construction, gridlock etc.
This is not a cruise control, you would still control the gas. However, if you pressed too hard on the gas your alert would start making the tone, and you would soon learn it is quite unproductive to keep pressing. (You could make this a cruise control but you need to be able to speed up some times to avoid things and change lanes.) People tend more often to speed up and then have to break for a short while waiting for the green, which doesn’t get you there any faster, and is a jerky ride.
The system I describe could be a nice add-on for car GPS systems.

I’ve been writing a lot about self-driving cars which have automatic accident avoidance and how they will change our cities. I was recently talking again with Robin Chase, whose new company, goloco attempts to set people up for ad-hoc carpools and got into the issues again. She believes we should use more transit in cities and there’s a lot of merit to that case.
However, in the wealthy USA, we don’t, outside of New York City. We love our cars, and we can afford their much higher cost, so they still dominate, and even in New York many people of means rely strictly on taxis and car services.
Transit is, at first glance, more energy efficient. When it shares right of way with cars it reduces congestion. Private right of way transit also reduces congestion but only when you don’t consider the cost of the private right-of-way, where the balance is harder to decide. (The land only has a many-person vehicle on it a small fraction of the time compared to 1-3 passenger vehicles almost all the time on ordinary roads.)
However, my new realization is that transit may not be as energy efficient as we hope. During rush hour, packed transit vehicles are very efficient, especially if they have regenerative braking. But outside those hours it can be quite wasteful to have a large bus or train with minimal ridership. However, in order to give transit users flexibility, good service outside of rush-hour is important. read more »

I’ve been remiss in updating my panoramas, so I just did some work on the site and put up a new page full of Alberta panoramas, as well as some others I will point to shortly.
The Alberta rockies are among the most scenic mountains in the world. Many have called the Icefields Parkway, which goes between Banff and Jasper national parks, the most scenic drive in the world. I’ve taken it several times in both summer and winter and it is not to be missed. I have a wide variety of regular photos I need to sort and put up as well from various trips.
This image is of Moraine Lake, which is close to the famous Lake Louise. All the lakes of these parks glow in incredible colours of teal, blue and green due to glacial silt. In winter they are frozen and the colour is less pronounced, but the mountains are more snow-capped, so it’s hard to say which is the best season. (This photo is available as a jigsaw puzzle from Ratzenberger.)
Enjoy the Panoramics of Alberta. And I recommend you book your own trip up to Calgary or Edmonton to do the drive yourself. I think you’ll find this to be among my best galleries of panoramas.
I also recently rebuilt and improved my shot of Ginza-5-Chome, Tokyo’s most famous street corner. While it was handheld I have been able to remove almost all the ghosts with new software.

As part of my series on the horrors of modern system administration and upgrading, let me propose the need for a universal API, over all operating systems, for accessing data from, and some control of the package management system.
There have been many efforts in the past to standardize programming APIs within all the unix-like operating systems, some of them extending into MS Windows, such as Posix. Posix is a bit small to write very complex programs fully portably but it’s a start. Any such API can make your portability easier if it can’t make it trivial the way it’s supposed to.
But there has been little effort to standardize the next level, machine administration and configuration. Today a large part of that is done with the package manager. Indeed, the package manager is the soul (and curse) of most major OS distributions. One of the biggest answers to “what’s the difference between debian and Fedora” is “dpkg and apt, vs. rpm and yum.” (Yes you can, and I do, use apt with rpm.)
Now the truth is that from a user perspective, these package managers don’t actually look very different. They all install and remove packages by name, perform upgrades, handle dependencies etc. Add-ons like apt and GUI package managers help users search and auto-install all dependencies. To the user, the most common requests are to find and install a package, and to upgrade it or the system. read more »

An eBay reputation is important if you’re going to sell there. Research shows it adds a decent amount to the price, and it’s very difficult to sell at all with just a few feedbacks. Usually sellers will buy a few items first to get a decent feedback — sometimes even scam items sold just for feedback. Because savvy buyers insist on selling feedback, it’s harder, and sometimes sellers will also sell bogus items just for feedback as a seller. eBay has considered offering a feedback score based on the dollar volume of positive and negative transactions but has not yet done this. Some plugins will do that.
One thing I recommend to low feedback sellers it to offer to reverse the “normal” payment system. If the seller has little feedback and the buyer has much better feedback, the seller should send the item without payment, and the buyer pay on receipt. Many people find this foreign but in fact it makes perfect sense. In real stores you don’t pay until you get the item, and many big reputation merchants allow payment on credit for known buyers. Another idea is to offer to pay for escrow. This costs money, but will make it back in higher sale prices.
However, here’s a new idea. Allow high-reputation sellers to “lease out” feedback, effectively acting as a co-signer. This means they vouch for the brand new seller. If the new seller gets a negative feedback on the transaction, it goes on both the new seller’s feedback and the guarantor’s. Positive feedback goes on the seller and possibly into a special bucket on the guarantor’s. The guarantor would also get to be involved in any disputes.
Seems risky, and because of that, guarantors would only do this for people they trusted well, or who paid them a juicy bond, which is the whole point of the idea. Guarantors would probably use bonds to issue refunds to badly treated customers to avoid a negative, though you want to be careful about blackmail risks. It’s possible the breakdown of true and as-guarantor negatives might be visible on a guarantor if you look deep, but the idea is the guarantor should be strongly motivated to keep the new seller in line.
With lendable reputation, new sellers could start pleasing customers and competing from day one.

Yesterday I attended the online community session of Web2Open, a barcamp-like meeting going on within Tim O’Reilly’s Web 2.0 Expo. (The Expo has a huge number of attendees, it’s doing very well.)
I put forward a number of questions I’ve been considering for later posts, but one I want to make here is this: Where has the innovation been in online discussion software? Why are most message boards and blog comment systems so hard to use?
I know this is true because huge numbers of people are still using USENET, and not just for downloading binaries. USENET hasn’t seen much technical innovation since the 80s. As such, it’s aging, but it shouldn’t be simply aging, it should have been superseded long ago. We’ve gone through a period of tremendous online innovation in the last few decades, unlike any in history. Other old systems, like the Well, continue to exist and even keep paying customers in spite of minimal innovation. This is like gopher beating Firefox, or a CD Walkman being superior in some ways to an iPod. It’s crazy. (The users aren’t crazy, it’s the fact that their choice is right that’s crazy.) read more »

The use of virtual machines is getting very popular in the web hosting world. Particularly exciting to many people is Amazon.com’s EC2 — which means Elastic Compute Cloud. It’s a large pool of virtual machines that you can rent by the hour. I know people planning on basing whole companies on this system, because they can build an application that scales up by adding more virtual machines on demand. It’s decently priced and a lot cheaper than building it yourself in most cases.
In many ways, something like EC2 would be great for all those web sites which deal with the “slashdot” effect. I hope to see web hosters, servers and web applications just naturally allow scaling through the addition of extra machines. This typically means either some round-robin-DNS, or a master server that does redirects to a pool of servers, or a master cache that processes the data from a pool of servers, or a few other methods. Dealing with persistent state that can’t be kept in cookies requires a shared database among all the servers, which may make the database the limiting factor. Rumours suggest Amazon will release an SQL interface to their internal storage system which presumably is highly scalable, solving that problem.
As noted, this would be great for small to medium web sites. They can mostly run on a single server, but if they ever see a giant burst of traffic, for example by being linked to from a highly popular site, they can in minutes bring up extra servers to share the load. I’ve suggested this approach for the Battlestar Galactica Wiki I’ve been using — normally their load is modest, but while the show is on, each week, predictably, they get such a huge load of traffic when the show actually airs that they have to lock the wiki down. They have tried to solve this the old fashioned way — buying bigger servers — but that’s a waste when they really just need one day a week, 22 weeks a year, of high capacity.
However, I digress. What I really want to talk about is using such systems to get access to all sorts of platforms. As I’ve noted before, linux is a huge mishmash of platforms. There are many revisions of Ubuntu, Fedora, SuSE, Debian, Gentoo and many others out there. Not just the current release, but all the past releases, in both stable, testing and unstable branches. On top of that there are many versions of the BSD variants. read more »
