The Supernova 2003 conference is running right now and as usual all the great and good prime movers are there.

Supernova (along with O'Reilly's recent conferences) is turning into a showcase for just how connected and wired a conference can be. Needless to say there's plenty of WiFi and the attendees are all using it. And here's what they're doing:-
- An official organiser's weblog
- A group weblog driven by trackback
- A conference Wiki
- Confab: an ad hoc conversational space
- A PhotoWiki
- Chiki: A chat session auto-archived to a wiki
- A bunch of IRC channels
- Group document editing via Hydra
- A blogroll of Speaker weblogs
- Numerous RSS feeds of all this.

Some of this is pretty experimental, but I wonder if all the tech could be bundled into a distribution and then sold to conference organisers as a managed package? [from: JB Ecademy]

I've just read Irina's post about Britney with a reference to the Russian Club in her signature. This was posted at 9:28. At 9:50 Google had these ads showing.

Kremlin Gifts Catalogue
1000's of Russian gifts by talented Russian artists. Secure, low prices

M. Lysenko "Best works"
Arias, cantatas, choir music of the famous Ukrainian composer on a CD.

How do they do that? It looks as though they're indexing pages with ads on them either as they are shown or very soon afterwards. Is this introducing a 2 tier web in the index? Pages with Google Ads are grabbed much quicker than the rest of the web? [from: JB Ecademy]

More Like This WebLog: Necho Feed - Tuesday, 08 July 2003

Look! A necho feed in the wild. Excuse me if I'm distinctly underwhelmed. It looks almost exactly like an RSS 2.0 feed with all the element names changed. Is this what all the fuss is about? Surely, there's more to it than this?

DON'T MESS WITH RSS. DON'T MESS WITH CITLD.

[edited to add]Maybe there should be a challenge. "Show something you can do with necho that you can't do with RSS 2.0"

Things to make you go hmmm? The Speedpass-enabled Timex watch is a watch with an RFID tag in it. On the surface this looks great. By giving you an electronic personal ID in the real world you can use it to pay for stuff just by waving it past a sensor. The bad news is when you get mugged. "No, you don't understand. You are going to give me the watch" [from: JB Ecademy]

I've added a feature where you can add a link to a FOAF file that is off Ecademy. If you have one, you'll know what this means. You'll also want to turn on Ecademy FOAF so that your Ecademy network can be picked up.

If you don't currently have a FOAF file and want to create one, take a look at FOAF-A-Matic.

To see the results, try my FOAF viewer or Jonathan's

If you're concerned about security with all this I'm careful not to expose anyone's email address or details unless they specifically enable it in Ecademy. [from: JB Ecademy]

The Register : Wireless rural BB service names the day from WRBB

WRBB says it will have coverage within 10km of the main centres. 10Km is quite a way to go with 802.11 under ETSI power limits. Interesting. [from: JB Wifi]

Two events in the Linux world with 802.11g

- Linksys release source for the GPL bits of their WRT54G This is less significant than it looks as the really useful bits like the Broadcom drivers are binary and closed source. But it's still interesting that a major AP is linux based and this may well ope up possibilities for some interesting hacking.

- The first linux drivers for the Atheros A/B/G chip set have been released. At last the Linux world can start playing with 802.11g hardware. [from: JB Wifi]

Dave's just noted that the RSS 2.0 spec seems to have disappeared from google. With all the noise about link and echo and stuff I'd been going to that page repeatedly. As I can never remember the url (and for some reason didn't bookmark it) I'd been using a Google search for RSS repeatedly. I too noticed a couple of days ago that it had disappeared. It's really bizzare. A search for "RSS 2.0" points to the old url not the current url. If you search for http://backend.userland.com/rss it finds it, so the page is still in the index.

I too am also concerned about Google's use of DMOZ descriptions on Google searches. I don't like it that a 3rd party provides the text for the entry in a search rather than the web page author.

While I'm on Google, I had the same thought about the Blogger button on the Google toolbar. I would have liked to have seen support for other blogging systems. but then I used it and realized that it really doesn't do much. It's not using the blogger API, it's just opening a window into the blogger edit. This is just like Manila Express or the many bookmarklets and IE menu hacks. So I'm really not sure how Google could have easily made it work with other systems.

Perhaps what we really need is a 3rd party toolbar that does the Google specific things that Google manage like displaying Pagerank. Then add in the Alexa specific things out of the Alexa toolbar. But to be honest most of this passes me by since I started using Mozilla Firebird all the time.

Uncle Dave wrote this not so long ago.theLizardBrainOfRss. Mark Pilgrim used this as a reason for leaving item.link out of his RSS 2.0 feed in favour of guid, saying "The RSS 2.0 spec introduces [guid] and clearly defines it as a way to express a permalink. The clarification of June 25th clearly deprecates [link] as a way to express a permalink, in favor of [guid]."

And yet I look at the Lizard Brain description and I see DW saying that the BBC, news.com feeds are using link correctly, but Simon Willison isn't, when all three are putting a permalink into link. Then he says "link should be used only to link to the article being described by the post, it should only be used in the TLD context". Unfortunately the piece starts with "Now for the third -- should he use link or guid to represent the permalink to the post? I believe he should use guid because that's what it was designed for. Link was designed for something else. "

I'm sorry, but I just don't get it. I don't know what DW is trying to say and why it's still ambiguous. I don't understand why Mark Pilgrim is saying that this article is telling him to stop using link. I'm still looking at all this and thinking that if you have a permalink, you should put it in the link element. I do agree that adding guid is a good idea. And if the most convenient guid to use is the permalink then by all means put that in guid. As well as link.

But. But I'm still where I was. Almost every spec, almost every feed that has links and almost everything DW has said tells me that link should be filled, if you can, with a permalink.

If you don't have a permalink, then leave out link. If you absolutely must, then put the most important link embedded in the description into link. But don't put the permalink into guid and leave out link altogether.

Please don't mess with the CITLD core of RSS. It works. Why are we still arguing about this? And why is still ambiguous?

Now the only reason I'm posting this here is that Mark has turned off comments on that thread. I'd post it to syndication@yahoogroups.com but despite having >600 members, nobody ever replies any more. I'm feeling intense frustration about all this because it all seems so stupid.

So I'll just continue to do what everyone else does (put permalink into link) and try not to get too worked up about it.

BTW. I tried out RSS Reader for Firebird. It's quite neat though I don't particularly like the approach. The problem is that it only uses title and link. Predictably it fails miserably on Mark's feed. Mark would say it's broken because it doesn't properly support RSS 2.0. I would say his feed is broken because there are aggregators out there who only use CITLD, the old lizard brain.

MIT has started a project called Open Government Information Awareness. It's very roughly an IMDB for government in the USA. A huge (hopefully) repository for information about the government. Source code is going to be available.

NTK asked at the weekend for people to port it to the UK. Perhaps an unemployed Ecademy developer with time on their hands could pick this up? Between us all I'm sure we could find somewhere to host it.

The Register

What we have here is a WiFi show with presumably WiFi specialists attending. A Security firm has big banners everywhere telling people they're monitoring traffic. Despite all that,What they found was that users checking their e-mail through unencrypted POP connections vastly outnumbered those using a VPN or another encrypted tunnel.

What will it take to get ISPs and Corporates to routinely provide SSL email and SMTP with Auth, and for their customers and employees to use it?

Passive eavesdropping is undetectable, but AirDefense picked-up 149 active scans from war driving tools like Netstumbler, Hmm. So its ok for AirDefence to monitor and track all traffic, but it's not ok for attendees to use Netstumbler to see what APs are running? Especially when Netstumbler really doesn't do a great deal more than XP or the typical wifi card client manager?

On Wed night Pierre Danon had a very strange take on WiFi on trains. I've thought for ages that this is an excellent location for all sorts of reasons. Being able to work in comfort and relative quiet on a long haul train journey or a long commute seems like a great idea that would encourage people to switch from cars or planes. Pierre's take was that people would use WiFi in the station to collect email, work on it while travelling and then send email via WiFi at the other end. huh? Now if he'd said "We see the need but getting bandwidth on a train is really hard" I'd understand. But suggesting that people don't want bandwidth on the train makes no sense to me. I'd like to see every first and business class seat have a power outlet and an ethernet jack.

Anyway, we're now beginning to see airlines work this out with satellite comms. We've seen this wek an announcement from India that they're working on bandwidth on trains. So my feeling is that this is inevitable. The real question is how?

So to any wireless engineers out there here's the challenge. How do you get broadband connectivity to a moving train reasonably reliably. Banks of 3G phones? High gain parabolas on signal boxes pointing up and down the track? Leaky coax? Gymboled sat dishes on the roof (what about tunnels)? [from: JB Wifi]

I had a question for Pierre when he announced the BT Hotspot-in-a-box that didn't get answered. The story is that all you need is the £400 box and an ADSL Broadband line and you can set up a hotspot with Openzone doing all the billing. But exactly what broadband do you need? Can I use my Home Openworld line which expressly forbids this in the AUP or do I have to take a business line which is twice the cost? Does the backhaul have to be via BT or can I use a more sharing-friendly and cheaper ISP?

Anyone got answers to this? [from: JB Wifi]
