I'll be speaking at three conferences in the near future, and can offer discounts to blog readers for two of them.
VoIP
Coming up October 19, I will be speaking on the future of SIP, and whether IAX2 or Skype might kill it, at the Pulver Voice on the Net conference in Boston.
Nanotech and Privacy

Tested my UPS systems and found them wanting in Friday's 10 hour Cupertino blackout. Last week I wrote about my longtime desire for a PC power supply that let you plug in an external battery for a cheap, long lasting UPS. But here are some other ideas.

We've gotten used to a painful, privacy invading security process when we fly. But why should we do this for shot-hop, small aircraft. Those ones on the 20 seat Canadair Business Jets and similar. Secure the cockpit with a sealed door and arm the pilot so that terrorists can't take control of the plane. Put in sealed transponders so ATC knows if the plane goes astray. Give the pilot a "disable" button that limits what can be done with the plane in the event of attempted hijack.

I like fine camera lenses, but the best quality are very expensive. There are many things that are hard to do in a good lens -- you want a sharp image, of course, over the full flat plane. Over the whole image plane you want low flare, high contrast and low chromatic abberation (ie. red and blue focus in the same spot.) And you want low distortions.

Most camera lenses try to be "rectilinear." That means they try to make a straight line straight in the image. This isn't actually natural, due to perspective straight lines are not straight.

So I wonder if we might soon see a new lens where no effort is made to fix distortions or make the image rectilinear, and all effort goes into the other factors. You are thus expected, with every image, to do digital post-processing to get a non-distorted rectilinear image. That will mean some small loss of image quality at the edges of the image, but probably a less distorted image than ordinary lens physics can deliver -- and a lot less cost -- in exchange.

Of course, this would primarily be for digital cameras, but a film user could also use the lens if they planned to scan their film for digital processing, as most do these days.

Down the road, each lens might contain within it the specifics of its own particular distortions, and the camera might be able to fetch this and either process directly or store it with the image for post-processing. Indeed, the lens might be a cheaply made lens with distortions due to the poor quality elements, or it might be a fine lens with deliberate distortions. (I have wondered if some P&S digicams might be doing this already.)

A lot of our democratic process involves our elected officials voting and presiding over things that voters are not going to change their vote over. Oh, they are important things, and the voters actually do care about them, but they are not going to change many votes.

That's especially true now. In deciding whether to re-elect your congresscritter, is how they voted on say FCC spectrum policy going to make a difference to you, compared to their stance on bigger issues like the war and the economy? Even when spectrum policy matters a lot to you?

Oh baby it's a wide world (And it's hard to get by Bangor, if you have to fly, Girl)

Oh Very Muslim, will you please leave us this time?

Generally, getting a case to use a camera underwater is expensive. The case has to be custom made for the particular camera, and it has to be full of waterproof push-through button-pushers for all the major controls. Digital cameras have helped a lot, since they can shoot far longer on a "roll" and things like zoom are electronic. They also sell in enough volume that some cases have gotten down to reasonable prices.

RVs come in all sizes, from 40' bus to towable pop-up. But what about inflatable in a trunk in the back of a minivan?

Setting up and tearing down tented campsites is a pain, and there are instant-setup tents and even some inflatable tents. But what about a super-duper inflatable tent, designed for car-camping.

Vernor Vinge (Vin-GEE)(whose 1993 novel "A Fire Upon the Deep" I published in hypertext form) coined the term "singularity" to refer to a future social and technological shift so profound and vast that those who come before it are actually incapable of understanding it.

This is an important concept, one that plays out in his novels and the writings of many others, and it needs a term. But this term has ended up not being ideal.

One core reason I haven't blogged much in the last while is the flurry of activity regarding my annual trip to Burning Man. I've prepared a page about one of my too-many projects this year, which was to build an incongruous phone kiosk in the middle of the desert which worked and let you call anybody in the world for free. It was battery powered, and used 802.11 and Voice over IP combined with a satellite internet connection.

I finally watched the closing ceremonies yesterday (did not see them while at Burning Man, obviously.) I liked the blinky balls that the children and audience members had, and the sense that the flame lit the LED ball. But it was just manual, people pushed buttons.

We all would love solar power to work better, but it's hard to have it make economic sense yet, at least if you're near the grid. A solar panel takes 4 years just to give back the energy it took to build it, and it never pays back the money put in if you compare it to putting the money into the stock market. And that's with full utilization. If you use panels and batteries, any time your batteries are near full the power is being discarded, and you also have to replace your batteries every so often and dispose of the old lead-filled ones. Yuk.

First entry in a while due to trip to Burning Man ... more on that later. This time I returned to RV rental, after 2 years in a tent, so I thought I would make some notes on that.

I regret to get in anybody's way, but the volume of comment spam I have been getting has been driving me nuts, and Movable Type makes it a royal pain to delete. There is no point in them spamming, I turned off putting links on URLs they include in the spams, but they do it anyway.

The movement for RFID in passports (and biometric passports) is growing. Belgium plans a trial later this year. As a privacy advocate I take some irony in realizing that this gives us what we have been asking for for ages.

Not having to show ID when we travel.

As I watch the Olympics on my Tivo, I'm having a hard time understanding how anybody could watch them without one. The number of events has become immense, and the coverage is 24 hour -- more than that, because I have both CBC and NBC coverage. (Plus CNBC, MSNBC and others, and I could buy TSN and Country Canada if I were desperate.)

At the Olympics, only in equestrian events do men and women compete on an equal footing, since it's about control of the horse, not strength. There used to be a truly mixed event in shooting (skeet and trap) but these were split in the 90s. (Perhaps shotgun experts will explain why this is, even though a woman won the last mixed event.) There are other mixed events -- Sailing, mixed doubles badminton, ice dancing, pairs skating, mixed doubles luge and so on, which are mixed by requiring a fixed number of men and a fixed number of women.

2 years ago, I got so frustrated at Bob Costas blabbing over parts of the Olympic opening ceremonies that clearly were not meant to be blabbed over that I rush ordered a satellite dish to watch the rest of the Olympics on the CBC.

(Besides, you find out there are events at the Olympics in which Americans are not competing for medals!)

I've been a longtime user of the Tivo, and when my mother got an HDTV, I pushed her to get a PVR. In Canada, the only really workable option for her was to rent the HD-8000 HD PVR from Rogers, her cable company. No Tivo service in Canada, and she wasn't ready for a PC based PVR (And HD ones are still immature.)

One of the thing that annoys Bush's opponents so much is that Bush does not appear to be the sharpest tool in the shed, and we feel the President should be so. I talked with Bush when he was running, and he wasn't as stupid as he appears on TV under all that scruity (nobody is, everybody reported that Quayle wasn't), but he's not at Clinton's level, for example.
