eBay has announced sellers will no longer be able to leave negative feedback for buyers. This remarkably simple change has caused a lot of consternation. Sellers are upset. Should they be?
While it seems to be an even-steven sort of thing, what is the purpose of feedback for buyers, other than noting if they pay promptly? (eBay will still allow sellers to mark non-paying buyers.) Sellers say they need it to have the power to give negative feedback to buyers who are too demanding, who complain about things that were clearly stated in listings and so on. But what it means in reality is the ability to give revenge feedback as a way to stop buyers from leaving negatives. The vast bulk of sellers don’t leave feedback first, even after the buyer has discharged 99% of his duties just fine.
Fear of revenge feedback was hurting the eBay system. It stopped a lot of justly deserved negative feedback. Buyers came to know this, and know that a seller with a 96% positive rating is actually a poor seller in many cases. Whatever happens on the new system, buyers will also come to notice it. Sellers will get more negatives but they will all get more negatives. What matters is your percentile more than your percentage. In fact, good sellers may get a better chance to stand out in the revenge free world, because they will get fewer negatives than the bad sellers who were avoiding negatives by threat of revenge.
As such, the only sellers who should be that afraid are ones who think they will get more negatives than average.
To help, eBay should consider showing feedback scores before and after the change as well as total. By not counting feedback that’s over a year old they will effectively be doing that within a year, of course.
There were many options for elimination of revenge feedback. This one was one of the simplest, which is perhaps why eBay went for it. I would tweak a bit, and also take a look at a buyer’s profile and how often they leave negative feedback as a fraction of transactions. In effect, make a negative from a buyer who leaves lots and lots of negatives count less than one who never leaves negatives. Put simply, you could give a buyer some number, like 10 negatives per 100 transactions. If they do more than that, their negatives are reduced, so that if they do 20 negatives, each one only counts as a half. That’s more complex but helps sellers avoid worrying about very pesky buyers.
Feedback on buyers was always a bit dubious. After all, while you can cancel bids, it’s hard to pick your winner based on their feedback level. If your winner has a lousy buyer reptutation, there is not normally much you can do — just sit and hope for funds.
If eBay wants to get really bold, they could go a step further and make feedback mandatory for all buyers. (ie. your account gets disabled if you have too many feedbacks not left older than 40 days.) This would make feedback numbers much more trustable by other buyers, though the lack of fear of revenge should do most of this. eBay doesn’t want to go too far. It likes high reputations, they grease the wheels of commerce that eBay feeds on.
One thing potentially lost here is something that never seemed to happen anyway. I always felt that if the seller had very low reputation (few transactions) and the buyer had a strong positive reputation, then the order of who goes first should change. Ie. the seller should ship before payment, and the buyer pay after receipt and satisfaction. But nobody ever goes for that and they will do so less often. A nice idea might be that if a seller offers this, this opens up the buyer to getting negative feedback again, and the seller would not offer it to buyers with bad feedback.

I’ve written before about both the desire for universal dc power and more simply universal laptop power at meeting room desks.
Today I want to report we’re getting a lot closer. A new generation of cheap “buck and boost” ICs which can handle more serious wattages with good efficiency has come to the market. This means cheap DC to DC conversion, both increasing and decreasing voltages. More and more equipment is now able to take a serious range of input voltages, and also to generate them. Being able to use any voltage is important for battery powered devices, since batteries start out with a high voltage (higher than the one they are rated for) and drop over their time to around 2/3s of that before they are viewed as depleted. (With some batteries, heavy depletion can really hurt their life. Some are more able to handle it.)
With a simple buck converter chip, at a cost of about 10-15% of the energy, you get a constant voltage out to matter what the battery is putting out. This means more reliable power and also the ability to use the full capacity of the battery, if you need it and it won’t cause too much damage. These same chips are in universal laptop supplies. Most of these supplies use special magic tips which fit the device they are powering and also tell the supply what voltage and current it needs. read more »

I want to enhance two other ideas I have talked about. The first was the early adoption of self-driving cars for parking. As I noted, long before we will accept these cars on the road we’ll be willing to accept automatic parking technology in specially equipped parking lots that lets us get something that’s effectively valet parking.
I also wrote about teleoperation of drive-by-wire cars for valet parking as a way to get this even earlier.
Valet parking has a lot of advantages. (I often joke, “I want to be a Valet. They get all the best parking spots” when I see a Valet Parking Only sign.) We’ve given up to 60% of our real estate to cars, a lot of that to parking. It’s not just denser, though. It can make a lot of sense at transportation hubs like airports, where people are carrying things and want to drive right up close with their car and walk right in. This is particularly valuable in my concept of the minimalist airport, where you just drive your car up to the fence at the back of the airport and walk through a security gate at the fence right onto your plane, leaving a valet to move your car somewhere, since you can’t keep it at the gate.
But valet parking breaks down if you have to move the cars very far, because the longer it takes to do this, the fewer cars you can handle per valet, and if the flow is imbalanced, you also have to get valets back quickly even if there isn’t another car that needs to come back. Valet parking works best of all when you can predict the need for your car a few minutes in advance and signal it from your cell phone. (I stayed at a hotel once with nothing but valet parking. The rooms were far enough from the door, however, that if you called from your room phone, your car was often there when you got to the lobby.)
So I’m now imagining that as cars get more and more drive-by-wire features, that a standardized data connection be created (like a trailer hitch brake connection, but even more standard) so that it’s possible to plug in a “valet unit.” This means the cars would not have any extra costs, but the parking lots would be able to plug in units to assist in the automated moving of the cars. read more »

Ok, I haven't had a new laptop in a while so perhaps this already happens, but I'm now carrying more devices that can charge off the USB power, including my cell phone. It's only 2.5 watts, but it's good enough for many purposes.
However, my laptops, and desktops, do not provide USB power when in standby or off. So how about a physical or soft switch to enable that? Or even a smart mode in the US that lets you list what devices you want to keep powered and which ones you don't? (This would probably keep all devices powered if any one such device is connected, unless you had individual power control for each plug.)
This would only be when on AC power of course, not on battery unless explicitly asked for as an emergency need.
To get really smart a protocol could be developed where the computer can ask the USB device if it needs power. A fully charged device that plans to sleep would say no. A device needing charge could say yes.
Of course, you only want to do this if the power supply can efficiently generate 5 volts. Some PC power supplies are not efficient at low loads and so may not be a good choice for this, and smaller power supplies should be used.

There’s a lot of equipment you don’t need to have for long. And in some cases, the answer is to rent that equipment, but only a small subset of stuff is available for rental, especially at a good price.
So one alternative is what I would call a “ReBay” — buy something used, typically via eBay, and then after done with it, sell it there again. In an efficient market, this costs only the depreciation on the unit, along with shipping and transaction fees. Unlike a rental, there is little time cost other than depreciation.
For some items, like DVDs and Books and the like we see companies that cater specially to this sort of activity, like Peerflix and Bookmooch and the like.
But it seems that eBay could profit well from encouraging these sorts of markets (while vendors of new equipment might fear it eats into their sales.)
Here are some things eBay could do to encourage the ReBay.
- By default, arrange so that all listings include a licence to re-use the text and original photographs used in a listing for resale on eBay. While sellers could turn this off, most listings could now be reusable from a copyright basis.
- Allow the option to easily re-list an item you’ve won on eBay, including starting from the original text and photos as above. If you add new text and photos, you must allow your buyer to use them as well.
- ReBays would be marked however, and generally text would be added to the listing to indicate any special wear and tear since the prior listing. In general an anonymised history of the rebaying should be available to the buyer, as well as the feedback history of the seller’s purchase.
- ReBayers would keep the packaging in which they got products. As such, unless they declare a problem with the packaging, they would be expected to charge true shipping (as eBay calculates) plus a very modest handling fee. No crazy inflated shipping or flat rate shipping.
- Since some of these things go against the seller’s interests (but are in the buyer’s) it may be wise for eBay to offer reduced auction fees and paypal fees on a reBay. After all, they’re making the fees many times on such items, and the paypal money will often be paypal balance funded.
- Generally you want people who are close, but for ReBaying you may also prefer to pass on to those outside your state to avoid having to collect sales tax.
- Because ReBayers will be actually using their items, they will have a good idea of their condition. They should be required to rate it. No need for “as-is” or disclaimers of not knowing what if it works.
This could also be done inside something like Craigslist. Craigslist is more popular for local items (which is good because shipping cost is now very low or “free”) though it does not have auctions or other such functionality. Nor is it as efficient a market.

I have written a few times before about versed, the memory drug and the ethical and metaphysical questions that surround it. I was pointed today to a story from Time about propofol, which like the Men in Black neuralizer pen, can erase the last few minutes of your memory from before you are injected with it. This is different from Versed, which stops you from recording memories after you take it.
Both raise interesting questions about unethical use. Propofol knocks you out, so it’s perhaps of only limited use in interrogation, but I wonder whether more specific drugs might exist in secret (or come along with time) to just zap the memory. (I would have to learn more about how it acts to consider if that’s possible.)
Both bring up thoughts of the difference between our firmware and our RAM. Our real-time thoughts and very short term memories seem to exist in a very ephemeral form, perhaps even as electrical signals. Similar to RAM — turn off the computer and the RAM is erased, but the hard disk is fine. People who flatline or go through serious trauma often wake up with no memory of the accident itself, because they lost this RAM. They were “rebooted” from more permanent encodings of their mind and personality — wirings of neurons or glia etc. How often does this reboot occur? We typically don’t recall the act of falling asleep, or even events or words from just before falling asleep, though the amnesia isn’t nearly so long as that of people who flatline.
These drugs most trigger something similar to this reboot. While under Versed, I had conversations. I have no recollection of after the drug was injected, however. It is as if there was a version of me which became a “fork.” What he did and said was destined to vanish, my brain rebooting to the state before the drug. Had this other me been aware of it, I might have thought that this instance of me was doomed to a sort of death. How would you feel if you knew that what you did today would be erased, and tomorrow your body — not the you of the moment — would wake up with the same memories and personality as you woke up with earlier today? Of course many SF writers have considered this as well as some philosophers. It’s just interesting to see drugs making the question more real than it has been before.

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.

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.

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 really wish I could find a really good calendaring tool. I’ve seen many of the features I want scattered in various tools, though some are nowhere to be found. I thought it would be good to itemize some of them. I’m mostly interested in *nix — I know that on Windows, MS Outlook is the most common choice, with Exchange for sharing. read more »
