Since this is not yet documented, I figured I would mention this here now... we are experimenting with some very rudimentary keystroke navigation in the discussion2 system. We support both FPS style WASD keybindings, as well as the standard vi layout of HJKL. Down/Up will cycle you through next/previous comment chronologically... left/right will cycle you through next/previous in thread order. Holding SHIFT down while you press the navigation key will collapse the previous comment. And when you get to the end, pressing down or right will attempt to retrieve more comments if you want them.

What this means is that you can now use D2 to simulate most of the most popular viewing modes of the original discussion system. By dragging both the abbreviate & display sliders right next to each other you effectively remove abbreviated comments which simulates nested mode. By toggling comment retrieval order to 'Oldest First' and using up down, you can effectivel read the discussion from oldest to newest. And of course the default settings gives you the best comments first, providing a nice default view of discussions for most anonymous users (who rarely participate and we want to really show only the best comments).

You can also disable D2 in the comment prefs (the word 'prefs' in the floating dialog box) if you are logged in. Right now we're testing D2 for a large percentage of anonymous readers. As soon as we finish IE7 support we'll roll out D2 for the rest of the ACs.

The Ann Arbor party seemed to go great- lots of people packed Leopold Bros place, doing battle with barflies and football fans. It was somewhat bizarre watching obvious normal bar people try to figure out what this large crowd of 'different' people were all about. We handed out a ton of t-shirts, drank much alcohol, ate nachos etc. Our party had a great number of Slashdot and SourceForge staffers... all folks who have been with Slashdot for so many years it's hard to remember Slashdot without them. I'm not exactly sure how many people eventually showed up... a lot of our RSVPs didn't show, and a lot more didn't bother sign up at all, so I think the two balanced out.

For me personally these sorts of things are always difficult. I'm not very good at crowds. I can smile for a picture, but I'm perpetually nervous when surrounded by strangers who have certain expectations of me. There's a reason I live life behind a keyboard!

Further compounding matters lately is baby induced chronic sleep deprivation. Me want REM cycles. It's always nice to get out and have a beer. Kathleen & I get only so many hours "out" together now, gotta make each one count. The party attendees were all cool... and understanding that I was pretty tired.

Anyway, thanks to everyone who showed up... I've still got the california party later this week. Hopefully my throat heals up by then. The only real problem with this location was the acoustics... I had to shout to be heard, and stick my ear in front of people to hear them (baby crying has done some amount of hopefully temporary ear damage). My throat is raaaaw from yelling. Sucking on cough drops helps.

As for other parties, boxes have been shipped. Hopefully they have arrived to most places on time, although I think they were shipped on a slowish shipping option so I'm not sure. I know some folks got shirts on friday, but I'm sure the others will arrive monday or so. Also, keep in mind that we only had 700 shirts and 2300 attendees from 136 parties with more than 5 attendees. So obviously not every party is getting a box... when we sent out the bulk mail, we had over 100 replies, and I'm sure there was nowhere near enough to fill even that.

But shirts or not, I hope your parties go well. Remember to submit videos or pictures or whatever to anniversary at slashdot dot org for your chance at the $1k ThinkGeek gift certificate grand prize.

So if you only count anniversary parties with 5 or more attendees, we have 128 venues with a grand total of 2366 attendees. The largest parties include Pudge's in seattle with 129, mine in Ann Arbor with 194 and Hemos's in CA with 197.

I'm sure that there will be many RSVPs that no show, but still, that's still an awful lot of interest. We'll be shipping shirts to a good number of those parties, but we have triple the attendees to shirts available, so we'll see just how far we're able to spread the love. Emails will be going out to party planners in the next couple days to get postal addresses.

As we're nearing 100 signed up people for the A2 Slashdot anniversary party, we've changed the venue to Leopold Bros... it's just a block south from the other place and they can handle us. I've also got word that we'll be printing a few hundred extra shirts since there was already like 50 parties with 5+ people in attendance. We certainly won't have enough for everyone, but we'll make a good dent in it.

I will of course put this information into a story next reasonable chance I get for a story, but I figured at least I could get the word out there. The anniversary party entry on the official page has been updated with the new location & address.

The A2 party already has like 70 signed up. We're going to have to rethink venue or time I think if we really have that many people. Wait a few more days and see what we can work out. Keep reading in the party forum for info. We have 500 shirts to print and hand out... it'll be fun to see where they go.

more info as I get it. There will be notes on future stories as days get closer.

Again, no formatting, just saving the story and links. This article got pulled because it's a dupe of one from several weeks back, maybe even a few months ago. I remember seeing it; it may have been this February article on Graphene Transistors, but I thought it was more recent than that.

Edit: The article has been restored. I guess the previous article was way back in February, so this one adds useful information.

Science: Replacing Copper With Pencil Graphite

"A key discovery at Rensselaer Polytechnic Institute could help advance the role of graphene as a possible heir to copper and silicon in nanoelectronics. Researchers believe graphene's extremely efficient conductive properties can be exploited for use in nanoelectronics. Graphene, a one-atom-thick sheet of carbon, eluded scientists for years but was finally made in the laboratory in 2004 with the help of everyday, store-bought transparent tape. The current research, which shows a way to control the conductivity of graphene, is an important first step towards mass producing metallic graphene that could one day replace copper as the primary interconnect material on nearly all computer chips."
Researchers are now hot to pursue graphene for this purpose over the previous favorite candidate, buckytubes (which are just rolled-up graphene). Farther down the road, semiconducting graphene might take over from silicon at the heart of logic chips.

(By the way, it's strange that I can't get a Science icon. I went for the Sci-Fi icon instead, for lack of anything more appropriate.)

If any of you are using an iPhone and are willing to help test out some Slashdot handheld crap, shoot me off a note... my email is the same address as always, and if you can't guess it, you probably can't help anyway ;) I've built a stylesheet and Tim put together a few little options that we think will make a few bits of Slashdot look nice on an iPhone (or really most lower resolution displays) but unfortunately none of us actually HAVE one yet... so anyway, let us know. Or if you work at Apple, send us freebies dammit!

I'm going to try the rapid-response, no-formatting method again.

MacBook Hacked in Security Contest

"Macaulay, a software engineer, was able to hack into a MacBook through a zero-day security hole in Apple's Safari browser. The computer was one of two offered as a prize in the "PWN to Own" hack-a-Mac contest at the CanSecWest conference in Vancouver. The successful attack on the second and final day of the contest required a conference organizer to surf to a malicious website using Safari on the MacBook -- a type of attack familiar to Windows users. CanSecWest organizers relaxed the rules Friday after nobody at the event had breached either of the Macs on the previous day."

I'm too tired today to add the fancy formatting, sorry. I've got two other ghosts from last month sitting on my hard drive, and I don't want this one to join them for fear of ectoplasmic overload, or something. So here's the basics:

Science: "Smart Dust" to Explore Planets

Ollabelle writes
"The BBC is reporting how tiny chips with flexible skins could be used to glide through a planet's atmosphere in swarms to gather data and report back. 'The idea of using millimetre-sized devices to explore far-flung locations is nothing new, but Dr Barker and his colleagues are starting to look in detail at how it might be achieved. The professor at Glasgow's Nanoelectronics Research Centre told delegates at the Royal Astronomical Society gathering that computer chips of the size and sophistication required to meet the challenge already existed.'"

Update: Good thing I didn't go to all that trouble, because the article was only playing dead. It went to "Nothing to see here", but remained in red on the front page and eventually went live.

I can't believe I missed it. I had a ghost slip right through my fingers!

When I came to work, I fired up my list of morning bookmarks. After checking email and half a dozen news and message boards, I got around to Slashdot. I ctl-shift-clicked the two red links and went on to read another dozen or so sites, and even went and got some work done.

When I happened to click the Slashdot links in another window, I saw "Nothing to see here. Please move along." Yikes! That meant that between when I first fired up the browser and when I shift-ctl-clicked, the article met its untimely (or perhaps just-in-timely) demise.

But there's nothing left of the ghost. I'd already gone on to read other Slashdot articles, and Opera 9 no longer seems to keep cached versions of pages -- when you hit "Back", it reloads with the current version.

I don't even know the original title of the article. All I have is the URL... like a feeling of cold in a creaky old house on a warm summer night.

Rest in peace, http://yro.slashdot.org/article.pl? sid=07/03/06/1227222

The Radical OLPC Security System
Posted by kdawson in The Mysterious Future!
from the tighter-than-yours dept.

CHaN_316 recommends a Wired article about the One Laptop Per Child project entitled "High Security for $100 Laptop":

"The laptop... will premiere a security system that takes a radical approach to computer protection. Krstic's system, known as the BitFrost platform, imposes limits on every program's powers. Every program runs in its own virtual machine with a limited set of permissions... Krstic contrasts this approach to Microsoft's Windows XP where every program, including Solitaire, has the right to access the web, turn on the video camera, open spreadsheets and send e-mail... 'This kind of model makes it more difficult for glue between applications to be built,' Krstic said. 'But 99 percent don't need glue.'"

What are the Ghosts of Slashdot?
As a Slashdot Subscriber, I get to see stories before they're posted to the general public. This means that I get to see the mistakes -- the articles that almost made it, but got sent to the cutting room floor at the last minute. They become the Ghosts of Slashdot, a URL that points to nothing.

Note that this is NOT the same as whining about article submissions that didn't get accepted! These stories were accepted, posted for subscribers, and then pulled from the site. Their brief existence gives us a glimpse into the Slashdot post-submission process, for those who are interested in what's going on behind the curtain.

By the way, any Subscriber can join the Ghost Hunt, but so far only morcheeba has shown the requisite sensitivity to ectoplasmic vibrations.

Ghosts of Slashdot: 02/06/2007
[Wow, it's been a ghost-free new year up until now. Kinda dead, you know. (groan) But here's one, though it may come back from the dead -- I suspect it got pushed from the front page in favor of the news of the DNS Root Server attack. The DNS story is also posted by "kdawson" who, oddly, doesn't have a link for his/her name -- perhaps it's this one? :) ]

Ogg Vorbis Gaining Industry Support
Posted by kdawson in The Mysterious Future!
from the chicken-or-the-ogg dept.

An anonymous reader writes

"While Ogg Vorbis format has not gained much adoption in music sales and portable players, it is not an unsupported format in the industry. Toy manufacturers (e.g. speaking dolls), voice warning systems, and reactive audio devices exploit Ogg Vorbis for its good quality at small bit-rates. As a sign of this, VLSI Solution Oy has just announced VS1000, the first 16 bits DSP device for playing Ogg Vorbis on low-power and high-volume products. Earlier Ogg Vorbis chips use 32 bits for decoding, which consumes more energy than a 16-bit device does. See the Xiph wiki page for a list of Ogg Vorbis chips."

In the early 1800s, sparsely populated southwestern Missouri was shaken by the largest earthquake recorded in the continental US: the New Madrid Earthquake, estimated at an 8.0 on the Richter scale. Since then, cities along the Mississippi River from Memphis to St. Louis have wondered when the next one would hit. Maybe never, say researchers at Northwestern University. The rock deep underground is cold and dead, and 1812 may have been the fault's dying gasp.

The discussion2 system had 2 notable changes in this weeks code refresh that I'd love to hear feedback on (use email if you can't post here). The first is Scott's very excellent new draggable slider control. Everyone mostly figured out the slider tool before, but it was very unresponsive... but no longer! It has some layout niggles under some browsers, but it functions properly in most of them.

Equally exciting is new dynamic updating... the old code actually transferred the full discussion and displayed/hid content as requested by your settings. Thew new code properly requests comments as needed, and when needed. This cuts page sizes dramatically for people reading with filters turned up very high. It also puts us a few stone throws away from a 'refresh' button which can just add newly posted comments in place. There's some work to be done yet, but it's made a lot of progress. I hope you like it.

We've tested everything under most of our most common browsers... if you're curious they are very roughly FF2 38%, FF1.5 19%, IE7 8%, Safari 7%, Opera 3%. Missing from our compatibility list is IE6 with 13% of our traffic. Fixing IE6 is non-trivial and we'd certainly take patches... but since the IE6 population lost a point or two last month anyway, and fixing the code is pretty substantial, we'll probably be focusing our development time on the larger and growing platforms (FF2 and IE7 obviously being the most important).

Anyway, merry-whatever-you-believe to everyone out there. I'm spending my holidays the same as always- driving from family gathering to family gathering. Roads suck but the person I like being with most is in the car too, so it doesn't matter.

If you have enabled the Discussion2 beta, you will notice a number of confusingly titled links appearing in comments. These control expansion/contraction of threads in several different ways. They are confusingly titled because we want you to try each of them and let us know which ones you like best without concerning yourself explicitly with how they work.

You can email your feedback to me (try d2 at cmdrtaco dot net) or some of you can actually post here.

I think next week will have a patch with a number of D2 changes (including some results from this experiment hopefully) so your help is really appreciated.
