Support public/private in 802.11 access points

Almost everybody has a WiFi (802.11) access point these days. Some leave them open by accident, some deliberately, some turn on encryption or other security. Being open can be nice to neighbours and wanderers, though it can also be abused, and if you have insecure machines on the local NAT, it's risky.

Foresight Conference

The weekend of May 14th, I will be attending (and MCing for part of) the Foresight Senior Associates Conference. This conference is always a lot of fun, with many at the edge (and beyond) ideas about nanotech, AI, anti-aging and other related topics. It's run by my friends Chris Peterson and Eric Drexler and their Foresight Institute. You may have read Eric's book "Engines of Creation."

Accelerometer in Cell Phone for emergencies

In writing the previous entry, another idea came to me that I stuck at the end which is worthy of its own entry. Place an accelerometer in your cell phone that will detect a violent event, such as a car crash or bike crash. Similar to the detector already in the car that triggers the airbag.

Upon detection of the event, the phone would start beeping for about 30 seconds warning about the emergency. If there is no emergency, you would press any key to stop the call. Otherwise it could call 911.

Why don't cell phones have USB?

In line with earlier thoughts about univeral DC power, let me ask why cell phones haven't standardized on USB (or a mini-USB plug) as an interface?

USB provides power. Not as much as some chargers, but enough to get a decent rate to many phones. And it has data, which can be used for phone control and configuration, speakerphone and headset interfaces, address book sync, ringtone download, memory card download, data-modem connections to PCs and anything else, all with one standard plug.

Offshore patient monitoring

As you might guess from the prior entry, somebody I know recently had an ICU visit. The hospital had to cut back staff, laying off nurses' aides and hiring some extra nurses, then making them do the former work of the nurses aides (changing sheets etc) because of regulations forcing them to have a higher ratio of patients to nurses. So, more nurses per patient but the nurses end up doing less actual nursing per patient because they are doing the work the aides did. Clever, no?

How can the US have been a player in new Iraqi constitution?

The new constitution of Iraq says:

Article 7.

A) Islam is the official religion of the State and is to be considered a source of legislation. No law that contradicts the universally agreed tenets of Islam, the principles of democracy, or the rights cited in Chapter Two of this Law may be enacted during the transitional period. This Law respects the Islamic identity of the majority of the Iraqi people and guarantees the full religious rights of all individuals to freedom of religious belief and practice.

Political action in anger

The recent attacks in spain appear to have affected the outcome of the election. Some say the voters rejected the pro-US stand of the former government. Others say they rejected the botched handling of the early investigation. Whatever reason, it seems the terrorist attacks altered the election, since the government was considered fairly solid before, and experienced quite the upset.

New mobile domain another bad idea

You may have seen a new proposal for a "mobile" top-level domain name for use by something called "mobile users" whatever they are. (The domain will not actually be named .mobile, rumours are they are hoping for a coveted one-letter TLD like .m "to make it easier to type on a mobile phone.)

Centuries ago, as trademark law began its evolution, we learned one pretty strong rule about building rules for a name system for commerce, and even for non-commerce.

Political Spam == Campaign Finance Reform?

I've maintained for some time that while most spam is commercial, whether something is spam is not dependent on it being commercial. Charity spam, religious spam and political spam are just as bothersome as Viagra spam.

However, fellow EFFer Larry Lessig challenged me on this by asking whether we might want to allow political spam. Spam is super-cheap to send (that's one reason it's a problem) but as a very cheap form of advertising it could be an equalizer when it comes to campaign expenses, since a candidate would low-funding could spam almost as well as one with boatloads of special interest money. That's unlike TV advertising, where the better funded candidate wins the game.

I have to admit that the current way elections are funded and political influence is bought and sold is a much more important problem than spam, so this is a question worth looking at.

Of course, it would be stupid for a politician to spam, even though they have exempted themselves from the spam laws. Spam generates such ill will (appropriately too) that I think a spam campaign from a candidate would backfire. Plus, I really don't like the idea of regulating spam based on what it says -- If it says one thing it's banned, if it says another it's OK.

But is there a germ of something worthwhile in here? What if the election officials managed the mailing list and voters had to be on it, for example.

Undefeatable commercial elimination

I've written elsewhere about the doom of the TV commercial, and as you may know, we represented Replay TV owners in their fight to not be declared lawbreakers for skipping commercials..

Commercial skipping tools have existed for some time, my old VCR has a complex automatic commercial advance. DVR makers have been scared against doing it for a while it seems.

Exercise bike that makes you exercise

Everybody knows one of the big problems with exercise machines is they end up as clothesracks. I've seen this literally happen. A lot of people put their machine in front of the TV to make them use it, for a while we even had no couch.

Here's an invention to create an exercise machine you'll really use, if you watch TV. The machine, or a device attached to it, would be programmed to constantly broadcast a recorded infrared signal trained from your remote. This code would be one that would interfere with watching TV. For example, volume-mute or channel-up, or a digit. Whatever you want to train it to. (Off doesn't work as that also turns the TV on.)

However, once you get on the machine and start using it, it stops sending this code, and you can watch TV. Once you have done your exercise quota, it would stop sending the muck-up code until you are next due to exercise, whatever your schedule is.

To stop you from just covering the transmitter with clothing (remember the clothesrack?) it would also need to have a receiver some distance away which gets upset and chirps annoyingly if it can't see the regular ping from the transmitter.

Others in the house not on a regimen could enter a code on the remote to temporarily disable the system when they want to watch. If 2 or more people had a regimen, they would have to enter which person they were to activate their disabling code. That gets a bit messy but it can be done.

Fantasy a risk in moviemaking?

At the Oscars last night (which were pretty boring, with one nice joke featuring Billy Crystal camcordering a new movie) Peter Jackson thanked the Studios for having the courage to back a big fantasy epic like the Lord of the Rings.

But a look at IMDB's list of all-time movie revenues reveals something else. Of the top 25 grossing movies of all time, how many were science fiction and fantasy?

Down with P2P software that isn't P2P

No surprise that after the RIAA started filing lawsuits against people they allege were distributing lots of copyrighted files, a movement has sprung up to build filesharing networks where the user hosting data can't be traced so easily.

Today, on Kazaa, all they need to do is try to find a file, look at what a user is sharing and try to download it. That gives them the IP address of the party in question.

Big Brother Tivo

Each year when Tivo reminds people they gather anonymized viewing data on Tivo usage by reporting superbowl stats, a debate arises. A common view is that it's OK because they go to a lot of work (which indeed they do) to strip the data of the identity of the user.

As noted, I've read Tivo's reports and talked to Tivo's programmers, and they did work hard to try to keep the data secure and anonymised.

Car dock for my MP3 player

I like to use our Rio Karma MP3 player in the car, but it's not nearly as good as it could be. So here are some jottings on what an ideal car dock would do for the player.

  • Power and charge the player, of course
  • Offer various options for sending audio to the car, including a built-in quality FM transmitter, a port for a special Cassette sized interface (more below) and various cables for car stereos that have an accessory jack (as mine has for a trunk CD-changer) or plain audio inputs.
  • A wireless remote control to stick on the wheel (not needed if other remote control methods can work.)
  • A microphone.
  • To get really fancy, an 802.11 interface to allow it to sync up with computers inside the house while in the driveway. Though strictly, this would be even better inside the player, not in the dock.

The microphone would perform several roles. One, it would detect the ambient sound level in the car, and boost the music volume as the car gets noisier. No more super-loud when you start the car either.

Secondly, it would listen for the sound of the music the player is playing. It would try to tell if it was playing, so it could detect when the stereo is turned off or switched to something else, or when the car is turned off (if the loss of power from the accessory jack doesn't already reveal this.) When the sound stops (even if this takes 5 seconds to confirm) just pause the music back in time when the sound was first detected to stop. One could then from time to time send out pulses of the forthcoming audio, and if it hears them, treat that as a resumption of play.
