Slashback: Playstation, CueCat, Games

This edition of Slashback has updates and clarifications on the official release of Sony's PS2 Linux, relative security among various operating systems, dirty output on power-boosted Linksys wireless access points, and more, flying hardware you might have figured was no more, and more.

Maybe a bad day at the factory? An anonymous reader submits: "I'm not sure where the other fellow got his WAP11, but mine don't show the dirty output his does." See this diagram for a much more desireable outcome, if you care to play with (a little bit of) fire.

First application should be a GPL'd AIBO obedience school. gonz writes: "An update to the previous reported linux on ps2 kit has been submitted by Sony Computer Entertainment Europe (SCEE) to the people previously registering interest on their technology sites. The update consist of that it will be released in May on both SCEA (us) and SCEE (pal areas, including Europe and Australia) territories. A website has been set up at this place. On a side note, registering for notification when pre-ordering can apparently be done too: 'Finally, although sales haven't yet started, if you send an e-mail with the message "subscribe" to ps2linux-request@technology.scee.net we'll let you know when pre-ordering starts.'"

Lessons in obviousness. John Kozubik writes: "I have written an article describing, in a manner I have not yet seen, why the court decision by the U.S. appeals court in SF that claimed in-line linking was not fair use was inherently flawed. It is a short piece written for both the technical and the non-technical, and I think it raises a strong point concerning the arbitrary nature of browser behavior."

If they'd launch some pigs, perhaps global phones would be affordable. Guppy06 writes: "Many of you may be surprised to learn that Iridium (famous for trying to compete with cell phones and failing miserably) is still throwing up satellites (I sure was). The article on CNN tells of the technical woes of getting this particular Delta II off the pad in Vandenberg as Iridium tries to put five more spares into orbit."

Couldn't they have spayed or neutered them instead? Speaking of old hardware, Anonymous Radio Shack Employee writes: "RadioShack has sent a notice to all of its employees to destroy all CueCats (preferably with a hammer). Apparently the CueCat is among a couple of dozen items that RadioShack has given up on, and wants destroyed. The memo says that store employee's can not benefit from the items on the list. Which sucks because my store has over a hundred of these things just sitting in the back room." This week's Linux Weekly News has a great, detailed followup to the recent flap over relative OS security sparked by a post in Windows Informant.

Re:How does one do that thing with oscilloscope?

[John Miles]

I saw some cheap used oscilloscopes in a local electronics surplus store at the weekend. If I got my hands on one, how would I go about measuring the frequencies like those guys did with their Linksys? Does one have to buy an antenna, or can it be made? Do all oscilloscopes have the necessary inputs for this. Are there any other considerations? Is this directional (depending on antenna, I guess)?

The instrument used to make those screen shots is a spectrum analyzer, not an oscilloscope. Both instruments display amplitude on a vertical scale, but an oscilloscope displays amplitude versus time while a spectrum analyzer displays amplitude versus frequency. They are very different tools, and any serious RF hacker will own both.

In general, an analyzer is much more sensitive (they normally display RF signal power on a log10 scale, so their dynamic range in voltage terms can exceed 100,000,000:1.) If you had a fast-enough/fancy-enough oscilloscope, you could run an FFT on its display and get the same basic information, but the SA is still the tool of choice for most RF work above 500 MHz. The insanely-fast scopes that can do microwave FFT analysis come with Ferrari-size price tags (literally), and they still don't have the dynamic range of a $3,000 spectrum analyzer. Different horses for different courses.

Sorry for the rather basic questions, but I'm not an EE, and I've only used an oscilloscope very briefly about 12 years ago. I really want to find out where the interference for my 2.4GHz phone is coming from, and how moving the base station helps. I also want to put an FM transmitter on my sound card, and so I want to see how that works too.

For both of those purposes, a spectrum analyzer would be the right way to go. An analyzer capable of 2.4 GHz coverage can be had for under $2K on eBay, but not much less. Some 802.11 hardware can give you reasonably-decent pictures of the 2.4 GHz spectrum, so I'd investigate that possibility first. :)

Re:Your own personal CueCat

[Technician]

This makes *far* more sense than what you have described your Radioshack does.
Two words.. Labor costs. A portable CD player that sells for $50 costs less than that to manufacture. If the laser or spindle motor or such goes out, you have at least an hour troubleshooting, ordering parts, looking up part numbers, keeping inventory of unique parts, replacing the part, aligning and warrenting the repair. You break even with techs at $20 per hour how?? Short answer.. replace it. Very little sold in radio shack sells for over a $100.00. I used to fix VCR's when they were a 600 to 1200 dollar item. Now that they are a 60 dollar item, I found other work.

Re:Maybe its like bagels?

[ncc74656]

Talk to anyone that works in a bagel or donut shop and they will tell you that they throw away hundreds/thousands of units a week. Basically what isn't purchased is discarded. Surely we can think to give the units to the homeless/hungry/needy-cause, but there is apparently a legal reason not to do so.

My first job ever was at a franchise of a certain somewhat large fast-food chain, and it wasn't long before I asked why the food that was "QC'd" was pitched instead of held and shipped off to one of the local shelters. Liability was the primary reason...if some bum got sick off of a freebie burger, he could've contacted any of the hundreds of ambulance chasers in this town and sued the store into oblivion. It was hella wasteful...about the only thing you could do is keep an eye on production to minimize the waste, but it was nearly impossible to eliminate it completely.

Re:Destroy the Cue Cats?!?!? Hell No!

It's too late, they already are selling them on eBay!
