Updated by HeUnique: LynuxWorks has also wrote a response (only this one is a bit more detailed).

An Anonymous Coward writes: "Embedded linux vendor Lineo has apparently caved in to Victor Yodaiken, and become the first software company to publicly announce the licensing of Yodaiken's patented process for running a general purpose operating system (such as Linux) as a task under a real-time kernel(such as RTLinux or RTAI)."

There's a special report at LinuxDevices which includes . . .

• text of the Lineo press release
• comments from Victor Yodaiken
• news of a non-patented open source alternative ("Adeos")
• a reference list about RTLinux and the RTLinux patent
• a whitepaper about Adeos

There's an interesting quote where Yodaiken claims his patent will help open source."

Dorm writes: "The American Solar Challenge, a 2300-mile cross country solar-powered car race begins on Sunday in Chicago. The 10-day race follows old Route 66 (parallels I-55 from Chicago to St. Louis, I-44 from St. Louis to Oklahoma City, and I-40 from Oklahoma City to Los Angeles) to downtown Claremont, California where teams will cross the finish line on the afternoon of July 25th. If you live along the race route or will be in the area, take a look at the media stop schedule on the ASC site and stop by to see some of the cars during the race. Some teams (including ours, Iowa State) will also be displaying their cars Saturday on the front lawn of the Museum of Science and Industry in Chicago, where the race begins on Sunday." The submitter has more info about Iowa State's entry below.

"Many teams (as well as Iowa State) are using advanced technologies like lithium batteries, near space-grade solar cells, and composite materials such as carbon fiber and fiberglass in their cars. Additionally many of us are utilizing Linux with amateur radio and satellite data phones to monitor weather conditions and to help optimize energy usage.

"We run a LinuxPPC server in our solar car chase vehicle that receives GPS coordinates from a Motorola Encore GPS receiver that is driven by a Lineo uCdimm board running uClinux. The uCdimm board reads in the GPS coordinates and broadcasts the coordinates every second via UDP packets on the ethernet network in the van. The LinuxPPC machine uses the coordinates to track our position and to display upcoming route information (stop lights, turns, road contitions) and to aid our racing strategy. Additionally, the LinuxPPC machine connects to the Internet via a Globalstar satellite phone to periodically download weather maps and forecasts for our current location. We also use GPS and amateur radio with APRS in our other support vehicles to monitor all of our vehicles' positions.

"Most of the code that runs everything is developed in house with C/C++, some of it with the Qt library. Myself and another member of our team will be preparing a detailed presentation in September for our local Unix users group about how we've utilized Linux on our team. If there is interest, I'll post the URL here for that once we've got it prepared.

"A list of other teams competing in ASC next week is available online at the American Solar Challenge web site. Most are university teams from North America, but there are some international teams as well."

SEWilco has comprehensive report from the Spring Comdex show in Chicago. Good listing - show was smaller, but I think there was still some good exhibits put on there. Click thru to read more- you can also read the final report that Newsforge has.

"At Spring Comdex in Chicago, Linux was scattered around the exhibit floor in addition to the cluster under the Linux pennant. There were quite a few embedded and handheld Linux items in addition to the expected Linux software booths.

• Identifiable small Linux things:
• The Agenda PDA had high visibility.
• In the Korean booths, HNT was showing several tiny Linux machines in their Exilien line, using Linuette from MIZI. I won't call these multimedia devices a PDA.
• Hacker & Packers had Linux inside their web pad design.
• Up front, Century Software was showing their embeddable Linux on some Compaq iPaq handhelds, although their WebMedia (not yet on their web page) is aimed at larger appliance-sized devices.
• Milletech was showing a WinCE or Linux webpad prototype.
• Tuxia was tucked in the NEC area with their settop/webpad/thin client software.
• Lineo featured tiny boxes, although their line ranges up to high-capacity clusters.

• The assorted Linux items that caught my eye:
• Appgen was showing their personal-to-Fortune range of accounting applications.
• ACCPAC has some of their accounting modules on RedHat.
• FreeDesk.com was showing their collection of web/Java based services and applications.
• Equinox was showing the Linux label due to Linux support for their multiport serial/modem line.
• Linux support in the distributed machine control system *this, which is generalizing proprietary industrial control equipment.
• Starnet X-Win32 helps an unstable desktop access your stable server windows.
• neTRAVERSE was running MS-Windows 95/98 apps within Linux.
• A GeekCruises.com brochure for a Fall Linux Lunacy cruise was floating about.

In addition to Linux Magazine, Linux Journal, and Embedded Linux Journal, Pen Computing magazine chose to feature the Agenda on their cover.

The overall Comdex exhibit area seemed smaller than two years ago, with Waste Expo taking the south hall this year. But maybe the way the space between the three buildings was arranged was deceptive."

zonker writes "This article at C|Net says the army is going to try an embedded version of Linux to use on portable vehicle diagnosis devices. Red Hat got the contract. Here is an article at Red Hat's site." Not a huge deal fiscally, but this is one of the areas where Linux is probably going to grow the most - hence companies like Lineo and others like them.

sconeu writes "Wired News has this article wherein they claim that they like hackers, and that the whole thing is overblown. It says that 'Doug Davis, Digital Convergence's CTO, said he applauds the hackers' ingenuity and 'chuckles' at some of the ideas they have dreamed up.' " Meanwhile, driver sites remain offline and software writers continue to be threatened. That's how much they like it. C'mon, guys.

Just noted that CueCat is going for this year's Useless Legal Action Beanie by going after www.upcdatabase.com, a site that is storing UPC codes and allows people to look them up. The database contains almost a half a million entries right now. Unfortunately they're not distributing copies of their database, so it may be necessary to create an open db just to make sure that this data isn't locked up. Update: 09/28 08:14 PM by CT : Lineo's cuecat site was taken down also.

On Aug. 30 several folks who have written Linux drivers and apps relating to the free barcode scanner mentioned here a few days ago were sent cease and desist orders demanding that they stop distributing the code. [updated by timothy 20:00 GMT: Please note that what flyingbuttmonkeys received is not officially a "cease and desist" letter; instead, it merely says that the longer the drivers are available, the "longer damages will accrue," citing "intellectual property rights owned by Digital Convergence." ] The barcode scanner is called a CueCat (with some lame marketroid colons that I'm not using because it irritates me when people name things like that). The code included a device driver written by Pierre-Philippe Coupard and a reader/decrypter written by Michael Rothwell. The code is afaik unavailable, but hopefully folks who downloaded it will have mirrors soon. I asked Michael to describe to me what his decoder did, and a few other questions.

> How complicated is the driver/what does it do?

It isn't terribly complicated. There's two programs that I wrote in the package, and one I did not. All are based on the "libcue" I wrote, also in the package. The deocder algorithm is a simple modified base-64 XOR 67. Jean-Philippe 'JP' Sugarbroad figured it out, and Colin Cross wrote code based on it and made me aware of it. I re-implemented it for the learning experience. The program named "decode" reads in a line of output from the cuecat for stdin or as first argument. CueCat output looks like this:

<ALT-F10>.C3nZC3nZC3nYDhv7D3DWCxnX.cGf2.ENr7C3b3DNbWChPXDxzZDNP6.

decode splits the Cue output into fields separeted buy ".". It ignores the first field and runs the rest through the base64+XOR decoder. This becomes the first line output. Digital Converegence added some additional "encryption" to their Web service; their program takes the output of the cuecat and inverts its case befoe sending it off to http://[server].dcnv.com/CRQ/1..[activation code].04.[cuecat scan].0

[Server] can be a, o, s, t, or u. [activation code] is supposed to be the activation code you get from your registration, but can be simply "ACTIVATIONCODE", which is actually what my spftware puts there. [cuecat scan] is the raw output of the device, minus the ALT-F10, with case inverted. Their servers send back a little blob of text containing several fields, including a suggested URL and description. Libcue parses those out and makes them available to its clients. Here's the scan of an NADA car-guide book:

The output of decode looks like this
DATA 000000001768443202 IB5 978034533392650599

CUE 0345333926
AMAZON 0345333926

The gnome panel applet reads in CueCat scans, looks up the :Cue at DCNV servers, and redirects Netscape to the suggested site, if any.

> What does their commercial software do exactly?

The same thing mine does, without the amazon lookup and with some annoying GUI features, like a tabbed CueCat panel.

> How many lines of code?

1258 according to "cat cuecat-applet.c cuecat-applet.h decode.c decode.h libcue.c libcue.h | wc -l"

Michael makes another interesting point in a seperate e-mail

When they sent the letter (Aug. 30), my software did not touch the DCNV servers to look up :Cues. It simply decoded the data, and if an ISBN number was scanned, the panel applet made Netscape go to the Amazon page blindly: http://www.amazon.com/exec/obidos/ASIN/[isbn number here].

So it was not the use of DCNV servers they objected to, but the mere decoding of the output of the cuecat. I didn't release the :Cue and Amazon lookup-enabled version until yesterday (Aug. 31), when the FedEx letter arrived by overnight delivery.

Thanks to Michael for taking the time to answer this stuff. It's pretty scary when the stuff that you have can't be poked at without a corporation demanding you stop. Imagine if Ford had said you can't open the hoods of your car a hundred years ago.

Update: 09/01 02:49 PM by CT : Freshmeat has a perl script CueCat Decoder that will also decode the CueCat's output.

Update: 09/01 02:57 PM by CT : Russel Nelson pointed out that Lineo's Driver has also been taken down following a cease and desist from Digital Convergence (CueCat's parent).

Nooooooo! Noooooooo! Not another Slashback! Especially not one dripping with the not-unexpected but unexpectedly-quick news which will let you use your spankin' new Rat Shack Scannin' Cat for other things. And with tons of pictures and a superb wrap-up of LWCE which puts mine to shame! Not to mention ... well, you will have to read more.

Thanks, Marc! Hey, he should charge an admission price for this one. This is perhaps the most comprehensive coverage of LWCE I've see yet, and if you're considering going this is a great way to whet your appetite for the next one.

Don't be alarmed, but we're going to have to give you a cat scan. MP3Car writes "The Dudes over at MP3Car have decoded the protocol used by the CueCat which you can get for free at Radio Shack. they have a Web page where you can scan in any barcode and it will tell you the number. Very neat and hightech space age hack. CueCat HACK"

A free package of Slashdot goodies to the first person who can make my Visor into a CueCat basestation so I can scan random items at the grocery. Note: As of 23:55 GMT, a search for "Radio Shack CueCat" at Google yields a grand total of zero (0) matches. Updated: 3:15 GMT 26th August by timothy: An unnamed correspondent writes:

Auckerman writes "It seems someone wants to put all standards and platforms for the entire history of computing on one graph. Pretty ambitious, if you ask me. Though, it would be nice if someone began recording these relationships before they are permanently lost forever."

Heck, I'd like to see this even if it covered only a history of video games!

Q: Will you visit my apartment? A: Yes. Speaking of collaborative knowledge systems, GutterBunny writes: "This week's I Cringley talks about Chris McKinstry's latest project - the Mindpixel Digital Mind Modeling Project. It's a pretty cool idea. Take about 900 million mindpixels (basic nuggets of truth about the human condition), throw them into a neural net, then let the neural net think out the next 100 million mindpixels. The article goes on to talk about how McKinstry's going to make money from it and some of the ideas behind it."

If the therapy was scuccessful, you may recall the fascinating interview that Chris gave to Slashdot a little while ago. Looks like some of the questions that people had then about Mindpixel(s) will be answered by reality.

Snarfvs Maximvs wrote to us with the news Lineo's Embedix Linux 1.0 for embedded x86 devices is out, with a distribution ready for download. One of the areas of interest is the WinCE compatibility layer that's currently in development - anyone know anything more about that? And what's going to happen now that Transmeta's "Mobile Linux" is out and about as well as Lineo?

Fourier writes "There's an article on NewsAlert that says Lineo has released Embrowser, an embedded micro browser designed for applications like set-top boxes. It is currently being ported from DR DOS to the infamous Embedix. " I guess this means that not only do we have another browser for thin-clients and low-end hardware, Linux will have more leverage in the embedded market. Licensing terms are unclear, however...
