You know, the newest Linux wireless drivers have moved _everything_ into software -- thus the ability to throw up an AP on demand.
Where can I find out how to do that? I researched this reccently, hostAP only works with cards that have built in support for being a master. I'd like to use cheap cards in routers made from old PC's to act as access points in mesh networks instead of operating in ad-hoc mode. What about the performance issues, will this work on early pentium hardware?
WEP is broken by design. A few engineers who don't know anything about cryptanalysis making their own encryption system that turns out to be broken is quite plausable however wifi standards are set by the IEEE. The IEEE is not stupid.
Was WEP deliberatly broken to make government snooping easier? That may seem ludicrus now but what if the likes of consume suceed in their goal of building mesh networks across citys? Securing wireless connections at VPN or application level is so much hassle that only 0.01% of users bother.
The reaction of the American government to the new Chinese wifi encryption standard lends weight to this theory. Supporting WAPI just means hardware manufacturers have to write a bit more software. Once it's in the software it will no doubt be supplied as standard worldwide. It may actuall be secure with little work. Why else would the American government threaten retailation over somthing so obscure?
a '3' phone is a 2.5G service Hmm, that would explain why they are ignoring the people petitioning them for internet service.
So 3G is not failing in the UK - IT IS NOT IN THE UK! Actually vodafone launched their 3G service a few days ago. Up to 384kbps down 64kbps up depending on how far you are from the cell and how many other people are using it. The coverage is just London and a couple of other citys.
100Mbps down is useless if it is priced at the same cost as sending data over the current UK 3G networks.
Orange's idea of "as much data as you like" turns out to be 100 megabytes a month. Vodafone charges the equivalent of 182 dollars (150 euro) for 500MB per month. "Three" is unwilling or unable to even provide a data service over it's 3G network.
The official bittoreent client and the popular variations like abc and shadows are not spyware but there are a few around that have adware/spyware added. It's open source, opportunists are free to do that sort of thing. You may have mispelled when searching like the people who end up at the fake site kazza.com instead of kazaa.com
No. Waste, mute, winny and freenet use variations of the "proxy the traffic" idea but emuleplus does not. It is just another client for the edonkey network. Emule plus transfers data directly between uploaders and downloaders.
If it overwrites the first few sectrs of the harddrive, as opposed to the first few sectors of the partiton, then it will take out the MBR which contains the partition table. You can have a physical disk broken up into several partitions eg a 60Gb disk that is partitoned as a 10GB C: drive and a 50GB d: drive.
Who knows who windows will interpreit a partition table containg random data, it might boot far enough to write to the drive using a mistaken idea of how big the partitions are reducing the chance of data recovery.
We are just guessing based on these first reports. Someone will analyse the worm properly in a day or two and give a better idea of how to deal with it.

it's a pyramid scheme. They call it "a matrix"
Matrixwatch has a lot of info on how these scams work and are involved in bringing a lawsuit against one of the biggest operators. They have instructions on how to report those annoying "free link!" auctions to ebay and how to get paypal to close the accounts of people who start new matrix sites.
There are a lot of people out there who are bad at maths and are unable to grasp that if they are the twentheth person to sign up for a plasma TV 50x matrix then they don't get their TV until 1000 people have join that list which will take years even if the matrix operator is not sued, shutdown by his card process and dosn't dissapear with the money or just not pay out when it's your turn. If you are signing up for place 20 to get a TV the chances are that people 1-19 are non existant or shills.
Ebay is slow to remove "free link!" auctions but they are certainly monitoring for people offering to sell goods outside of ebay. I doubt it a conincidence that transactions outside ebay reduce their income whereas matrix scams just annoy users. I reccently bid for a computer. I got half a dozen email message sent via ebay saying "I have ten of those really cheap, email me!" followed by half a dozen warnings from "eBay Singapore customer support" (I'm nowhere near singapore) which began "We recently investigated the possibility that 'newoffretez@yahoo.com's account was compromised and used by an unauthorized third party. Our records indicate that you may have been contacted by this third party about purchasing an item off of the eBay site."
Wouldn't this take up quite a hefty chunk of hard drive space?
No doubt it will be compressed so I'd expect it to be about 1.5GB for a typical consumer PC preinstalled with windows XP, DVD player, burner software etc. They will still describe it as having an 80GB disk,. not 75GB free space. Manufacturers are happy to save a few dollars by slowing down PC's with software modems and sound synthesis done in software so I doubt they will balk at this oportunity.

4" external verse 4" internal is the same thing. No it isn't. Firstly the users hand is around the phone and secondly the internal antennas are usually a small coil of wire. A 4" whip antanna stickout out the top of the phone has a considerably different efficiency and radiation pattern to a 4" whip a few millimeters away from the metal shields around the innards of the phone.
How wise is it to stick a 802.11 transmitter right next to your brain for extended periods of time?
This device 14dBm = 0.025watts My GSM phone 33dBm = 2 watts (with automatic power control so it dosn't allways use that much)
I'm not worried at all. Would you expect to see a rise in brain tumours by now considering the number of people with mobiles?
That said I think the SAR ratings for phones are completly bogus. A phone with a 4 inch pull out antenna may have a higher SAR rating but it transmitts more efficiently so it can contact the base with less power and the amount of power being absorbed by the users head is less than a tiny new phone with an internal antenna.
Nokia recently announced the next version of the nokia communicator. Triple band, edge, GPRS, bluetooth, infrared, wifi, qwerty keyboard, browser, organiser, telnet, ssh, plays mp3s, 80MB memory, camera, 640x200 colour screen.
A highly desirably toy, though judging by previous communicators there will be a dozen firmware updates and you will need the extended warranty because they often break.
>The exceptions are KDE 2.0 (which is slower than 1.0; >but 3.0 is faster than 2.0 and 3.2 is even faster than 3.0)
My expericance on an older machine is that KDE 3.0 is slower than 2.0
>Athlon 1.4 Ghz 390 MB RAM The fact you can see a difference on such a powerful machine indicates just how bad the problem is. It is possible to have a smooth user interface that reacts instantly on a 33MHz machine. You should not notice delays to to the window manager at all on a 1.4GHz machine, things like redrawing and opening new windows should happen in less time than it takes to display the next frame on the monitor.
The terrible performance of KDE is the biggest obstacle to linux on the desktop.
I also suspect that the developers are using the fastest machine available and don't consider speed issues. I also suspect they use the highest possible screen resoloution resulting in a restrcited working area at common resoloutions.
I sometimes use headphones as a concentration aid when working at a computer. I found listening to music distracing so I tried listen to white noise for a while. I used a radio tuned to an empty VHF frequency, ocasionally I'd hear voices drifting in from hundreds of miles away and end up playing ham radio instead of working.
I'v now assembled a playlist of no-vocals no-beats ambient music. Classical is ok but all the well known tracks remind of of adverts.
I slid a smartcard into the sleave and pushed a few buttons to designate whether or not this voter should receive a Democrat or Republican ballot
As an non-American I'm baffled by the practise of having voters
register which party they prefer in a government database.
The basic principle of an election is the secret ballot.
Why is this done? Why isn't it widely condemmed? Why do people cooperate instead of all claiming to prefer the monster raving loony party?
I don't reccomend picotech. My boss bought a ADC-216 when we needed an 50KHz spectrum analyser. I'd seen picotech equipment before and reccommended buying a spectrum analyser off ebay instead. When the picotech unit arrived I connected it in parallel with a conventional scope and tried it out.
I found several serious software bugs. I can't remember them all now.
It has an AC voltmeter function, the spec page claims 1% accuracy. It worked ok up to about 10KHz and above that the reading were completly wrong. The hardware is just a fast ADC so the PC software did the task of adding up the area of the voltage versus time graph.
A picotech support person reproduced the problems I found and promised to send a new version of the software. Months later after a few reminders they finally emailed me some software, the same buggy software I'd already been supplied with the unit.
Well, I'm sure that the folks who sell cables for $500 a foot will come to the rescue with $15000 power filters.
If you actually know a bit about physics, electronics and audio browising audiofool forums is hilarious. There are already people selling 50 pound isolating transformers and huge chokes to the golden-eared brigade. Suggesting they do a double blind test to see if they can hear a diference will not endear you to them.
Slashdotters who have done network programming or read the RFC's that describe how the internet works may have heard of John Nagle. He created the Nagle algorithm which combines small packets of data to avoid the dreaded Silly Window Syndrome.
There is the related story of another old time phone phreak. The Cheshire Catalyst got the number 321-LIFTOFF. IIRC he tried to sell it to the Houston tourist board who called in lawyers and discovered that it is not legal to sell a phone number. He told the story at the H2K conference in New York.
Regarding phone jammers, the cheap ones are usuall just a low frequency sine or sawtooth wave oscillator, a schottky diode to generate lots of harmonics and a couple of telescopic antennas are at about 1/4 of a wavelength long at 900 and 1800MHz. They produce plenty of noise on non-mobilephone frequencys as well.
Planning has begun for HEX2005, the next conference in the HEU, HIP, HAL series.

Yes, if you don't count university networks that has been using 6bone for several years now. Read up a bit on 6bone, and you'll see that the primary purpose of it is to function as a testbed for IPv6. But of course, computer scientists aren't really able to find and fix problems in the protocol.
It is reason to assume that new ip6 software will have _implementation_ bugs that open security holes. This is not about problems with the protocol. IP4 is a reasonable protocol but there have been plenty of problems caused by buggy implementations such as winnuke (large ping packets) and the fragment reassembly bugs in linux a few years ago.
Since software like an IP stack in a operating system tends to same once it works reasonably even with new OS releases introducing a new protocol does carry a much higher risk of new widespread security holes.
"Each about 500 bytes in length" - wrong, i can change my packets to 15Kb in size if i wanted, or even 512KB
You are being unecessarily pedantic. The article author makes that analogy that "You can think about these packets as tiny digital postcards, each about 500 bytes in length" which is a resonable simplification since in practise most packets are below the required minimum MTU of 576 bytes.
he doesn't realize that ipv6 is just called that because of the 6 areas to insert a IP address:
Are you making this up? IP4 packets start with a four-bit version field that contains the number 4, IP6 packets start with a four-bit version filed that contains the number 6.
"those routers don't have similar hardware that can route V6 in hardware: those packets have to be routed in software, which is a slower process." - all enterprise routers, which the Internet runs on, can have their roms changed, no changing of routers required.
ROM's hold software. he is refering to the difference between a general purpose processor executing some instructions that compare a destination ip to the entry in a routing table and physical logic gates that directly do the same operation. Custon logic is much faster than software and unless implemented in somthing reprogrammable like an FPGA, much less flexible.
I got an email from paypal a few days ago. I'm 99% certain it's genuine and not a cleverer-than-average attempt to get me to enter my details into a false website.
PayPal, Inc. is pleased to announce that we are preparing to introduce PayPal (
Europe) Ltd., a company incorporated in the United Kingdom, as the service provider for PayPal customers in the European Union.
We anticipate that PayPal (Europe) Ltd. will begin operating in February 2004,
subject to receiving authorisation from the Financial Services Authority (FSA)
in the UK. Please note, no action will be necessary on your part. You will be a
ble to continue using your PayPal account as you do today.
This sounds like a good thing to me. I expect the UK financial regulators will keep them on a tighter leash.
