On the wall now near desks are plates with power and ethernet (and phone until VoIP takes over.) I’ve been wondering if we shouldn’t add another jack — air, and plumb our walls with pipes to move air for cooling electronic devices.
This idea started by reading about a guy who attached a plastic vent hose from the output of his PC fan to a hole he cut in his wall. This directs much of the heat and some of the noise into the wall and up to the attic.
I started wondering, shouldn’t we deliberately plumb our houses to cool our devices? And even more, our office buildings? And can we put the blowers at the other end of the pipes, to move the noise away from our devices? How much would we save on air conditioning?

I’m an earlier adopter with my mythTV box and fast connection. But I’m really keen to see the move to getting TV shows over IP. Cable’s bulk pricing just isn’t doing it for me any more.
I get many shows now via broadcast digital TV, and while I think this is a giant waste of spectrum, while it’s there I will certainly use it. So I’ve started examining just how much I get from my cable. Of course your tastes will vary, but I find I’m starting to care about only 3 or 4 channels. And since I’m paying $45/month plus tax for expanded basic cable from Comcast, that’s a great deal of money per channel. Those channels would be wise to start becoming available over the net, because we early adopters will pay nice prices compared to what the cable companies are paying.
The key is that with the MythTV or other DVR, you stop channel surfing. You pick the programs you like, and it records all of them and you don’t watch random shows. (Except for Tivo-style “suggestions.”)
Even though you limit your TV to just a subset of shows, you quickly are surprised to change the “500 channels and nothing on” problem into “just a few shows and always something good ready to watch.” Surfing and deliberate watching are just that different.
So the shows on cable I’m watching are the Daily Show (and somtimes a few other Comedy Central programs), some SF shows on the Sci-Fi Channel, and Mythbusters on the Discovery Channel. Then, during certain events, I will go to the 24 hour news channels, the only things I ever find myself watching live. (Read on…)
Now news, as it turns out, is the one thing that makes sense to be broadcast. It’s the only thing (along with its cousin, sports) we all want to watch the moment it’s produced.
For the rest the delayed gratification of TV over IP, or even DVD rental through the mail, is just fine.
And indeed, the SF shows and Mythbusters will all appear on DVD 1-2 years after airing. The Daily Show is making itself available via the non-linux streaming media formats in reduced resolution, so it’s not quite ready for me, and it, as a form of news, needs to get to me right away. (The Daily show is on over the air TV in Canada.)
The TV shows on DVD are much better quality than analog broadcast, and of course inherently commercial free. They’re not HD yet, though. And the pointless delay, even though they get more money from people who buy or even rent DVDs than they do from advertisers at broadcast time. There is a 24 hour news channel made by ABC available over the air here.
The point is, if I could get my Daily Show in good quality and a format I can play on my system, I think I would be ready to drop my cable. The rest of my non-network watching would be on DVDs and the other brave shows willing to deliver to me this way, at a fair price — $1/hour for two adults, commercial free, if I buy in bulk. That would leave me without CNN, though the web is mostly substituting for that now, breaking news even faster than it does.
Of course there are people who watch shows from large numbers of channels who love the big bundling. They will hate this idea. But I expect most DVR users are seeing the number of non-network channels they watch drop, and the economics are changing.
(There are some intermediate alternatives. Dish Network has a $27/month package with the channels I want. Sadly, satellite systems don’t interface nearly as well with digital video recorders as analog cable does. Starchoice has a $20 CDN package but it has few of the classic cable channels, though it does provide The Daily Show, the Colbert Report, a couple of 24 hour news and lots of Canadian shows. About $18 USD after taxes.)

Washington, DC: The American Association for the Advancement of Science (AAAS) issued a stern warning today to Televangelist Pat Robertson. Robertson had recently condemned the citizens of Dover, PA to the wrath of God for not voting in a school board that would teach Intelligent Design in classes.
“We’d like to say to the good Reverend Robertson: if there is a disaster in your area, don’t turn to Science, you just rejected it from your life,” AAAS said on its daily television show broadcast from Washington, the 3.14159 Club.
“And don’t wonder why it hasn’t helped you when problems begin, if they begin. We’re not saying they will, but if they do, just remember, you just pushed science out of your life. And if that’s the case, don’t ask for its help because it might not be there,” they said. “In particular, you won’t have a phone to call the ambulance, and it won’t exist even if you could call it. And even if the doctor lived next door and you could call her, she would only bleed you and put smelly poultices on your forehead to balance your humours. And she would be a guy.”
“Actually, we’re just kidding,” the AAAS later corrected. “Science works whether you believe in it or not. That’s what’s really cool about it,” they said.
“What they said,” indicated Venezuelan President Hugo Chavez, in an independent statement. read more »

At my bank (Wells Fargo) and some others I have checked, the ATM lets you make a deposit with an envelope. You must key in the total amount being deposited, even if you put several cheques in the envelope. This in turn shows up as just one transaction in my statement, and in my download of my transactions to my computer.
That’s not what I want of course. I want to see the different deposits split out individually. The bank certainly splits them out in any event to send each cheque out to the bank that will honour it. Why not have me start the process. It might also assure more accurate addition of the amounts.
Of course, this would take a little more time at the ATM, but a lot less time than what I do now — put each cheque into a different envelope, and deposit them one at a time. Or at least put the cheques of different classes into different envelopes. Of course, if I planned ahead, I could enter them all into the accounting software before I go to the bank, and in that case need not enter the individual tallies. But you don’t always plan like this.
Does any bank’s ATM do this?
Of course even better would be to let me make my deposits at home, with my scanner. No, I’m not kidding. More and more, people are happy to get scans of their cancelled cheques back instead of the physical paper ones. The banks are moving to doing it all inter-bank with scans. So let the customer do it too. Of course, the system would scan the OCR digits with cheque number, account number and routing number and not let the same cheque be deposited twice. A live query could be made after you scan with the payer’s bank. And you would be required to hold on to the cheques you scan, since any one could be challenged, and if challenged you would have to bring the physical one down to the bank. And perhaps you would have to bring them all down eventually for final records.
And eventually of course I could duplicate paypal, by writing you a cheque and sending you a scan of it which you can then cash — in which case we should just go to full electronic money.
Naturally all of this would only be for well trusted regular customers, and the money would probably be on invisible hold in your bank account just like ATM deposits often are until the bank looks at them.

More and more often when I tour a museum these days, I’ll see either a computer terminal with some interactive exhibit, or a video screen or cinema to play a movie.
All well and good, these media are sometimes the best way to present what the museum wants to present. On the other hand, since there is never enough time on a tourist’s schedule to see all the things you want to see, or even all the exhibits in a good museum, I often find myself saying, “Did I fly 5,000 miles to watch a video or browse a web application?” So I sometimes skip these videos and computers in order to spend times on things unique to the area.
Of course in many cases the videos and applications are unique to the museum, but only artificially, because the museum has chosen to do things that way. They could easily, and should, put these exhibits up on the web.
Depending on the role of the museum they might put them up for free, for the world to browse, or they might put them up for a fee. They would do this if they felt that people would stop coming to the museum because the materials were available free.
Another alternative would be to print an access code on your museum ticket, or issue you an access code ticket on requests. These access codes could be permanent, or bound to the first few IP addresses on which they are used, or work for only a few days after first use, if they need that level of access control. Then I would know that I could watch that movie later, when I have more free time, and devote more time to the physical exhibits that I came for.

Hard disk drives these days are cheap. Too cheap, in that while we love paying 30 cents/GB, the reliability is getting pretty poor. Doing backups, especially automatic backups is a must, but what about RAID?
One of the problems with RAID, at least RAID-5 is that you need to have 3, and ideally 4 or 5 drives in a machine. That’s a lot of drives, a lot of power, a lot of heat, a lot of noise. And many machines only have two IDE controllers so they can barely do 3 drives and can’t readily do more even if they had the slots and power for them.
So I propose a software RAID-5, done over a LAN with 3 to 5 drives scattered over several machines on the LAN.
Slow as hell, of course, having to read and write your data out over the LAN even at 100mbits. Gigabit would obviously be better. But what is it we have that’s taking up all this disk space — it’s video, music and photos. Things which, if just being played back, don’t need to be accessed very fast. If you’re not editing video or music, in particular, you can handle having it on a very slow device. (Photos are a bigger issue, as they do sometimes need fast access when building thumbnails etc.)
This could even be done among neighbours over 802.11g, with suitable encryption. In theory.
Not that there aren’t some major issues to overcome. The machines must be on most of the time. (A single disk can be taken out of a RAID temporarily, and thus a single machine hosting one disk can be turned off or rebooted, but not for long periods.)
If you lose access to two disks (or your LAN) you can’t get access to the data. And it’s going to use a lot of your network capacity, though gigabit networking is starting to get cheap. And the idea gets better… read more »

(You might want to see Tivo’s actual press release about being able to move programs from a Tivo to an iPod.)
ALVISO, CA — NOV 21, 2005 — TiVo Inc. (NASDAQ: TIVO ), creator of and a leader in television services for digital video recorders, today announced an enhancement to it’s system which actually allows the copying of files from one computer
device to another, at least if its one of their partner devices.
The enhancement will include exclusive capabilities such as TiVo auto-sync that will allow subscribers to choose if they want new recordings of their favorite programs easily transferred to their portable devices via their PC. Every morning the devices can be loaded with new programs recorded the night before. This is similar to syncing technology available for decades on most computers, including the linux system Tivo is based on, but now in a revolutionary new feature, Tivo has put it back in.
“Sure, computers have always had the ability to copy and sync files, and we had to take all that stuff out of the Linux OS we built the Tivo on” said Tom Rogers , CEO of TiVo . “By enhancing our TiVo ToGo feature, we’re putting that back in, for our two specific partner devices, making it easy for consumers to enjoy the TV shows they want to watch though only if they have an iPod or PSP â€”whenever and wherever they want, unless it violates our other restrictions.”
TiVo said it will begin testing the feature in the coming weeks with a select group of TiVo Series2â„¢ subscribers who own the Apple Video iPod or PSP devices. TiVo said it plans to make the feature available to its entire standalone TiVo Series2 subscriber base as early as the first quarter of next year.
Last year, TiVo stopped disabling file copying for all its Series2 subscribers and called it the TiVoToGo feature. The TiVoToGo feature reducing the blocking of the normal ability to transfer TV shows from their DVR to a laptop or PC over their home network. From the PC, subscribers can watch the shows, or transfer them to devices compatible with Microsoft Portable Media Center format. Today’s announcement adds support for the Apple iPod and Sony PSP, as well as the ability to specify Season Passâ„¢ recordings to conveniently transfer to the portable device via the PC overnight. File copying is still blocked for all other devices.
Subscribers will need to purchase certain low-cost software to facilitate this revolutionary concept of copying files. To discourage abuse or unlawful use of this feature, TiVo intends to employ “watermark” technologies on programs transferred to a portable device using the TiVo ToGo feature that would disable the normal ability to have privacy over what programs you watch.

You've all heard the famous "Nokia ringtone" many times (hard to describe in text, it's 10 notes, often satirized on Trigger-Happy-TV) and even the polyphonic version.
I suggest that a symphony orchestra, around warmup time, should suddenly play this song with their full glory and set of instruments. This would be funny on its own, but could then be followed by a very memorable, "please remember to turn off your cell phone now in preparation for the performance." It might actually get people to do it.

We hate waiting in line at the cashier and stores don’t like paying cashiers so some have self-service cashiers which are still hard to use. So here’s an idea.
Provide shoppers who wish to self-serve a scanning wand, which is battery powered and attached by coiled cable to the shopping cart. In the shopping cart, have a number of shopping bags present and numbered. Paper bags which hold a square shape are better. Also have an open area or special bag.
As you pick up an item you scan it and put it in a bag. It would probably tell you which bag to put it in, though in some cases you could pick and tell it.
However, if the item is “unverifiable” then the scanner would indicate it should be put in the special bag.
An unverifiable item would be one whose weight can’t be reliably measured. That’s because the idea is to verify the main bags at check-out by weighing them. That weight should match the calculated weights for the items put in the bag, plus the weight of the bag of course. If the weight matches, the bag is just loaded back into your cart. If it doesn’t, the items are scanned by the cashier as they normally are today.
Sometimes, even in a bag that matches the weight, a random scan of a few items in the bag would be done. Along with a basic visual check every time. This is to stop people from gaming it, by finding expensive items (notably pills) that happen to in combination weigh close to what some cheap items weigh.
Items of very small weight would go in the unverifiable bag, along with the most expensive items (just so that clerks know that they should never see them in the self-checked bags on visual inspection). Items of large weight would not be put with items of tiny weight in the same bag. Bags would also be balanced by weight, and a smart system would know to put cold items together, and not to mix cleansers and food.
Variable weight items, like meat, usually already have their weight encoded in the barcode as they are priced by weight.
There already are self-checkouts, and they do use a weight check, but it’s one item at a time and they are a pain to use — so much so that I have seen people reject them with just a couple of items. I am guessing scan as you shop will seem to add almost no time. Of course you will need buttons on the scanner to remove items, and even to move them to other bags when it won’t hurt the measuring system.
Check-out will be with a cashier, but the cashier will simply place the bags on a scale, and if it beeps correct, put it back in your cart. They will do a quick visual scan (seeing the list of items and the order they were put in the bag on the screen) and if told to by the system, do a random item check. Sometimes they will even do a full re-scan of everything, but ideally this would be rare. Then they would hand check the specials bin, the way they check everything today. And then take your money. You should be through the cahsier in 1/2 to 1/3rd the time. A small number of cashiers would be open for those who wish to have everything personally rung up by the cashier.
Note as well that with this system you don’t need to bar code the individual products! It’s sufficient to have a bar code on the shelf tag, and to scan that, though of course people will get errors sometimes. The screen on the scanner would possibly show a picture of the item so you are sure you scanned the right shelf tag.
In the produce department, you would pick up vegetables, put them in a bag, and put them on the scale. It would show you the weight and price and also beam that to your scanner. Items priced by count would have to go in the specials bin unless they are all so close in weight that the scale can figure out the count based on the weight. I suspect this would work with most items in fact. (You would need to scan the shelf tag before heading to the counting-scale for these items.)
Of course it’s also possible that regular customers could just get dispensation to just put the bags on the scale and walk out (auto-billed to their credit card) but frankly I am not that in favour of systems (like the discount cards) which generate giant databases of everything you buy.

I don’t post most EFF news here, since the EFF has a news page and 2 blogs for that, but today I’m doing it
twice because congress is voting tomorrow on renewal of the PATRIOT act. There was a lot of effort to
reduce the bad stuff in the bill, efforts that seemed to be getting somewhere but were ignored.
Ok, do I have to tell you why this erosion of so many fundamental rights is a bad idea? At first,
I thought the PATRIOT only came about because in the weeks after Sept 11, the country was acting
in anger and shock. It did things it wouldn’t do with time to be calm and reasoned about it.
And the PATRIOT act has resulted in huge waves of new surveillance as we’ve been seing in the past
So do what you can to stop it. Our Action Center will help you contact your representatives to give them the message. Plus you can read the bill and
commentary on it on the EFF web site.
We’ve been saying these things for so long you may be getting tired of it. But every time we strip away
rights, make society a little bit more scared — each time we live in fear — I think that’s exactly
what terrorists want. Like the name says, their goal is to sew fear and terror in hope of getting their
way. Sure, people were angry when this law was first passed, but there is no excuse today. Take action
yourself. Donation to organizations like the EFF and others if you don’t have time to take all the action
you think you should, but do have the money. It’s as simple as that.

Today there's more evidence we should be taking more and more supplements, but they often come in giant pills that are uncomfortable to take. At the same time, easy to take chewable vitamin pills are also on the market.
So I propose: Divide up all the vitamins and minerals and supplements wanted in a daily regimen. Make a chewable pill that contains all the ones that can go in a chewable pill (ie. don't taste bad, and will maintain proper cohesion.) Then take the ones that can't go in that chewable, and bundle just them in a hopefully smaller, coated pill to swallow.

There’s talk that in the battle between the USA and Europe over control
of ICANN, which may come to a head at the upcoming World Summit on the
Information Society in Tunis, people will seriously consider “splitting
the root” of DNS.
I’ve written a fair bit about how DNS
works and how the
true power over how names get looked up actually resides with hundreds of
thousands of individual site administrators. However, there is a natural
monopoly in the root. All those site admins really have to all do the
same thing, or you get a lot of problems, which takes away most of
Still, this is an interesting power struggle. If a large group of admins
to switch to a new DNS root, different from ICANN, they could. The cooperation
of Microsoft, which includes the default root list for IIS, and Paul Vixie,
who puts that list in BIND, would play a large part in that as well.
many times in the past people have split the root by creating alternate,
roots which mirror the existing .com/.org/.net/etc. and add new top
level domains. Some of these have been “innocent” efforts frustrated
at how slowly ICANN had created new TLDs, but in truth all of them have
also been landgrabs, hoping to get ownership of more generic terms,
furthering the mistake that was made with .com. ICANN is also furthering
the mistake, just more slowly. (The mistake is ignoring what trademark
law has known for centuries — you don’t grant ownership rights in ordinary
All of these superset attempts have also failed. I don’t think I have
ever seen anybody promote a URL using one of the alternate root TLDs,
or give me an email address from an alternate root TLD. I consider
This is, of course, what creates the natural monopoly. Few people are
interested in setting it up so that two different people looking for a
domain get different results. That applies to the fact that most
people get an error for www.drug.shop (in the new.net alternate TLDs)
and a few get the registrant’s site, but it applies even moreso to the
Americans would get one answer for foo.com and Europeans a different one.
Because of this, Larry Lessig recently suggested he wasn’t worried
about a root split because there would be such strong pressure to keep
The difficulty is, what’s the point of creating your own root if you
can’t actually make it any different from the original? The whole
point of wanting control is to have your way when there is a dispute,
and to have your way does not mean just doing it the same as everybody
else lest we get inconsistent results.
It’s possible that a group of nations might try to wrest control in
order to do nothing at first, but eventually create a superset of TLDs
which would, for the first time, be a success. That might work, since
if all the nations of the world except the USA were to go to a new
root set, it would be hard for the private individuals in the USA who
control name servers not to follow. But then the new group would
no doubt attempt at some point to issue policies for the existing
top-level-domains and country code domains. read more »

I was amused to hear folks on PRI’s Marketplace radio program say that 99 cents for a rerun on the video iPod was a good price. Turns out that 99 cents includes commercials in that rerun, because people polled said
they would rather pay 99 cents with commercials intead of $1.50 without them.
As I have written before, the public sure is misjuding this. TV CPMs are about $10, or 1 cent per ad shown to a viewer. So in a half hour program, with about 15 ads, the network and everybody below them would have made about 15 cents to show it to you. 30 cents for an hour long show. At full resolution too, and the ability to record it without DRM to watch later. Yes, Apple gets a cut, is it that huge?
So 99 cents is no deal, though they are actually sacrificing more to cut the price 50 cents and include ads, unless they can target the ads better and thus get more revenue from them. Will you be able to fast forward on the downloaded shows?
My main lament has been about what a bad deal TV advertising is. You get $1.20 worth of programming to watch a full hour of pure advertising. Way below minimum wage.
I want to see TV available for download, but I think instead of this system should give us shows at a similar cost to the advertising based one (plus a retail markup) at better resolution to boot.

Everybody is annoyed at how long it takes computers to boot. Some use hibernate mode to save a copy of the system in a booted state, which is one approach. Booting procedures have also gotten better about running stuff in parallel.
How about watching a system as it boots, and noting what disk blocks are read to boot it. Then save that map for the disk defragmenter or other disk organizer and have it try to rearrange the files needed at boot so they are all contiguous
and close together. This should reduce the role of I/O as a boot bottleneck. Many disks today can read 50 megabytes in a second, and most OSs only need to access a few 100MB in order to boot, and they have the ram to only need to read files once.

After we picked up our rental car in Darwin in the Northern Territory of Australia, the blasting heat told us we would like a cooler full of drinks on our 3 day road trip through the outback. So we stopped at a Woolworths and picked up one of those terrible foam coolers, ice and some drinks. There was no bar code on the cooler so we wasted what seemed like 10 minutes in the checkout because the clerk wasn't authorized to ring up an item as general merchandise. (Hint to stores: I know you're scared of your cashiers stealing from you but this is ridiculous.)
It seemed to me that with a sizeable number of the renters in Darwin going off on outback road trips, who among them wouldn't want a cooler. So the rental company should offer a cooler pre-loaded with ice, and even perhaps some drinks. They would of course overprice this, but as long as it's not more than buying a decent cooler, people would go for it over those cheap ones, that can't keep ice long and run a risk of leaking into the nice rental cars in any event. There's other stuff that could go into the road-trip kit, ranging from walkie-talkies to umbrellas to snacks, too.

You may have heard of the idea of pollution credit trading. I’ve been pointed to two firms that are selling CO2 credits on the retail level for individuals, to offset the output from driving a car, heating a house etc.
I’ll get into the details on how it works a bit below, but if you have a car like mine that is putting out 5 metric tons of CO2 each year, you can for a low price (about $50, which includes a whopping markup) pay a factory somewhere to cut their own output by 5 tons, meaning that net, you are causing zero emissions. Which means you are reducing total emissions by a lot more than you would by switching to a Prius, and you are doing it at a vastly lower cost. (This doesn’t mean you shouldn’t drive a Prius, it just means this is a lot more effective.)
Normally pollution credits are traded only by the big boys, trading contracts with hundreds or thousands of tonnes of emissions. The retail firms are letting small players get in the game.
This is a fabulous idea, in theory at least, and also a great, if sneaky gift idea. After all, if you buy the gift of not polluting for your loved one all they get is a bumper sticker and a good feeling. At least it’s better than giving to The Human Fund in their name.
Here’s the catch. I went and priced the credits, and while www.certifiedcleancar.com wanted $50 to credit my car, the actual price of credits on the Chicago Climate Exchange is about $2.16 per tonne of CO2, or about $8 for my actual output as they calculated it. One expects some markup, of course, and even some profit for the company selling the retail credits, but this is nuts. I called the other company, Terrapass and got reasonably frank answers. First of all, they claim they invest more in wind power and other truly non-polluting forms of energy more than they just buy carbon credits. Secondly, this is still a small volume thing, and most of the costs are not the credits, but the $20,000 or so to become a member of the exchange, or so I was told. And of course, in small volumes, administrative costs can swamp the real costs.
Another outfit I found is carbonfund.org which is non-profit and cheaper. In some sense since people buy these out of guilt rather than compulsion (they were meant to be forced on polluters to give money to non polluters and make a market) non-profit might make sense, but they are also supposed to be a real market.
Still, if I pay $50, I would love for my $50 to mostly go to reducing pollution, not mostly to administration. Usually when exchanges are expensive there are members who will trade for you at much more modest markups. The folks at Terrapass said they were not yet profitable at the current prices.
And it is such a good idea. Read below for more on pollution credits. read more »

Yesterday I visited Tag Camp an impromptu weekend conference on tagging in the spirit of Foo Camp and the Bar Camp I wrote about earlier. User-applied tagging has become all the rage on sites like fickr and del.icio.us. I was pleased when one person at the conference saw my name and said, “hey you started all this.”
Well I didn’t really. Tagging is of course an ancient concept, espcially for personal use. And it’s been done formally by professionals like librarians in card catalogs and online databases.
However, back in 1983, in one of my many forays into fixing USENET’s newsgroup system, I drafted an RFC of sorts around the idea of a tag (or keyword) based USENET. I called it K News, or Keyword based News, and posted the KNews URFC
As today, people were of mixed opinions about tagging. You can see some of the discussion via Google Groups. It never went very far, but a standard “Keywords” header was added to the the USENET standard. Some used it but there was no critical mass. I wrote the newsclip filtering language which was able to filter on the tags. And for 18 years we have been tagging posts in rec.humor.funny with tags ranging from how funny the joke is, to whom it might be offensive to and so on. I don’t know how many people really use the tags to filter the group (it’s low volume) but I used them to build the web site for the newsgroup (which is of course netfunny.com.
Now, as noted tagging is the hot topic in online community and publishing. I lost faith in the concept, deciding users could not self-tag well enough. However, today the net is so big that even though users indeed do not self-tag well, you get enough people who do tag in ways you like to get useful stuff.
Of course, many of the people excited about tagging are in that state because they see it as a means to find even more cool stuff on the web. I’ve been moving to the camp that wants to find less stuff, higher quality stuff. There’s already too much good stuff to read, too much good stuff I have to discard. I can’t even read the blogs of my friends let alone all the truly interesting folks I don’t know. I hope that tags might help us along that path somehow, though it’s not the area of research right now.
But I thought a pointer to the history might be of use.
