Well yeah they aren't going after people trolling message boards, but I think you are getting a little over worried about no-knock raids (which don't have anything to do with the technology used to identify the location of the raid).
Against a limited mobility emitter, it is fairly trivial to identify the source of that emission with the right equipment. You could identify the model of the hardware you are using and an expectation on the antenna. Assuming that they are searching legally for an actual criminal statement (Let's say you made a threat of violence) If the searching agency goes to a judge with the paper trail I have listed, the data on which house they wish to search, and an expectation on the hardware they expect to find there, I doubt they would be denied an actual legal warrant.
My example was for someone attempting to make a political statement by simply passing through a wifi location once. Tracking that would be very hard.
For someone operating in a fixed location making actual criminal threats. Tracking that would be very possible.
the price of their preferred genuine Apple portable, divide it by the number of hours they spend hacking to keep things working every time there is a point update, subtract a bit for general annoyance, come up with a single-digit hourly figure, and if they have half a brain they'll just buy one.
Or if they're not capable of working that out they'll just post whiny little messages on Slashdot about how their freedoms are being repressed by the big bad company that chose not to support hardware they don't even ship.
I'd just rather companies didn't go out of their way to 'not support' ways in which they didn't intend their products to be utilized.
Should my television 'not support' my computer since their only input is VGA and my computer's output is DVI? Should they 'not support' that choice by implementing something that physically prevents me from using an adapter?
Great post, IndustrialComplex. To expand on that, using a home made cantenna I can access someones WiFi from a block or more away. Using a LiveCD or just doing a low level format I can hide any trace of connecting to someones WiFi. I don't even need to leave my house. What are the police going to do, kick down every door looking for someone who made anonymous comments? Get real.
Even if they were for any reason to get access to my house and find a pringles can, some coaxial cable and a few BNC connectors, what are they going to do? Arrest me? I'm some geek who enjoys pringles and I'm a certified to install fiber optic and copper cable.
I actually considered using a cantenna as an example in my statement, however I believe that the simple obstacles involved in just finding someone that is actually physically present in the store are evidence enough that anonymous speech in the United States is very possible, and very difficult if not impossible to track except for a few, very rare, instances.
Knowing that this is Slashdot, I also didn't mention the cantenna because for anything outside of your house, someone could be pedantic and use that as an "Aha, the cantenna is obvious and will mark you as something odd in the area and therefore noticable". Also, if you REALLY pushed it by doing something that 'They' really did want to find out (Maybe someone leaking nuclear blueprints or something), using an antenna from a stationary location for an extended period of time would make it so that you could be tracked, eventually, but it would take a very dedicated search.
By some other method of transport? I used to cycle 10 miles to work every day, even in the middle of winter, and I'm not exactly the fittest person you've ever met. Unless Bob is physically disabled in some fashion (and if he is, I'd guess there's some kind of assistance he can get, e.g. a charity that will do his shopping for him if he can't get into town) he should be able to do this too
The point isn't that there are other alternatives, but that the other alternatives are so far behind society that they simply cease to be valid options for the exercise of your rights.
Everyone here is arguing this all wrong. Lets say that Bob got his license suspended because he doesn't want to give his 'implied consent' with respect to breathalizers and the like. He has done nothing wrong, but simply does not wish to submit himself to a search of his person.
If driving is not a right, then Bob's only alternative is to find another way to travel those 10 miles. Riding a bicycle ALSO falls under the jurisdiction of driving a car (A bicycle, under this interpretation is simply an unlicensed vehicle, but not one you have a right to use)
Bob's only real option if he wishes to avoid being searched, is to walk.
However, in the US it is now impractical to expect our population to be able to walk to work. By the simple virtue of the fact that if we expected everyone to walk, everyone would have to live in a city, and at our current population levels, is simply not an option. Therefore we are effectively mandating that a certain portion of our population NOT walk, and therefore be forced to submit to searches of their person.
Now, lets take that a little further, literally.
What if Bob lived in DC, and wanted to go to Sacramento, CA? In a previous thread I calculated the time it would take Bob to walk to California, and return to DC. That time is greater than 110 DAYS! If you factor in Bob staying in a hotel at the per-diem rate and eating approximately $10/day of food it would cost him over $10,000 to make that trip.
It is fallacious to suggest that walking is the only option by which a person may travel without subjecting themselves to violations of their Fourth Amendment Rights.
On all those situations you or your car will probably be video'd on CCTV or seen by someone and couple that with the time that you did whatever it was you'll be found pretty quick.
So lets say someone wants to make an anonymous statement.
Are you suggesting that 'they' are able to do this:
1. Know within a short period of time that Anonymous comment X was made by someone they wish to track down. 2. Subpoena the IP logs of the website where the comment was made (assuming that such logs are kept) 3. Receive the logs, determine which ISP the IP was assigned to 4. Subpoena the IP assignment table of the ISP and receive the cooperation of the ISP. 5. Assuming that the IP is correct, identify the location where the wifi router was. 6. Go to that location and take a guess as to which camera records to subpoena. 7. Subpoena the records of the cameras. 8. Hope that the cameras actually show something and that the data hasn't been overwritten. (Some only store 1 week of video) 9. Ask around and see if anyone saw any nefarious individuals using *gasp*, a laptop. (Who are you going to ask in a McDonalds? The people who are there now, or the people who have scattered to the winds 5 minutes after eating? The employees who are obviously savants and remember everything since they work at McDonalds and could easily identify someone using a laptop in their store 2-3 weeks ago)
10. Realize that the guy who posted the comment didn't even enter the store and simply typed up the statement/message in private and set it up to connect to the first open wifi location and didn't even have to take his laptop out of his bag.
*The DRM is not intended for BBC produced shows, we own them entirely and unlikely for independent UK shows (most of the BBCs programming), it is only a serious option for imported shows (which are almost entirely US shows)
So the exporting content holders have the choice:
Make $0 as the British simply download the already cracked shows
Make exactly the same amount of money that they would make broadcasting the shows to the BBC with or without DRM.
The thing is, I don't want to use Windows and install the umpteenth file viewer for the next flavor of DRM. They are making it so that if I want to watch anything at all, it has to be pirated.
Actually negotiating with your counterparty in a contract dispute is always cheaper and more productive.
It should be so far from not surprising I'm surprised that it had to be said.
Once you throw down the legal gauntlet, anyone you are dealing with now imagines, in bright red 30' letters, "Anything you say can and will be used against you in a court of law."
Ahh thanks, the term 'train' tripped me up, something like an automated-convoy seems more appropriate.
Though being able to set up some sort of mechanical linkage with a semi would be kind of cool.
You drive behind a semi, pull all the way to its bumper and click together like an actual train car. Put your car in neutral and let the truck driver handle it. Make the mechanical linkage robust enough to maintain the separation between your car and the truck if he slams on his brakes...
And the best part:
Include some sort of electrical connection that passes brake signals to your own signals, AND a transfer of data to the truck of your EZ-Ride account number. The truck then bills you per mile that you are attached to offset his additional fuel costs and wear and tear plus a 10% fee he keeps.
I had a professor that DID know what he was talking about, he decided that he wanted us to learn so much in a single course that this was a common occurance.
Professor arrives in class. 3 seconds later he has an overhead projector up and is now talking and writing directly on blank transparancy paper. The rate at which he was writing was near stream-of-consciousness. I typically took 20-30 PAGES of notes in a single lecture, and these notes were basically a transcription of his non-stop lecture. You couldn't afford to miss a single thing he said. He basically wrote one one sheet, slid it to the other side of the projector, and then started another one on the right side. If you were a fast writer, you could just finish up the previous page just as he completed the next.
The problem was that he did know what he was talking about, but it was the ultra-condenced version. You had to go home and take a few hours to review the classes transcript. Thankfully, he scanned his sheets and sent them out the next week. I doubt I could have survived that class on my notes alone.
Although it was nice in that since he wrote almost everything down, any accent barriers were inconsequential.
(The course wasn't a walk in the park either, it was our digital signals processing course)
This news is too late for a lot of people. However, preventing further damage is the first step in recovery (if recovery is possible). While the brain isn't technically viewed as a resiliant organ, it can partially recover if given enough time.
If we can stop the damage causing element, I wouldn't be surprised (I wouldn't hold my breath) if the damage reversed itself over time (which could be decades)
The problem with this approach is that the worse the disease, the more snake-oil you can find out there, promising to cure you and your wallet of all of your ills.
For something that IS time sensitive like Parkinson's, I'd not lower the bar on claims, I'd lower the bar on the risk aspect.
In otherwords, lets say I make a claim that my drug does "A". I would like for the FDA to evaluate it for "A" and the major risks of "Will this likely hurt me more than help?"
Then once "A" has been sufficiently proven, and patients aren't immediately dying from liver failure or brain hemorrhages, I'd like to see the drug released with a medical disclaimer that it is still in the 'trial' phase and the negative effects have not yet been fully evaluated.
That way, you don't have snake oil (ineffective) treatments being sold, but you aren't holding off a treatment from someone who WILL die because the treatment may cause their hair to fall out. (Isn't that how we treat chemotherapy?)
Even though vehicle aerodynamics have tried to combat it, there is a big negative pressure bubble forming your car's wake 'pulling' it backwards. Partially filling it with another vehicle's high pressure region where it 'cuts' the oncoming air helps.
I would imagine that would only apply in a series of unconnected cars. When the cars are connected, that negative pressure bubble will exist at the end of the final car and exert the force on the pulling vehicle through the link system.
That doesn't occur for bikers since there is no linking mechanism for the rear vehicle to pull on the leading vehicles.
LOL. Not many other possibilities for an engineer around here.
I was offered the chance to move back to Owego, I'd been doing on-site work with a customer. The sad thing is the severance package looked more economically appealing than sticking around in the area. With the way the layoffs were handled for off-site employees, I wasn't going to put myself at risk again.
However to keep this on topic, I've used both AT&T and Verizon in Owego, and AT&T's coverage, as of earlier this year was still fairly hit and miss. I'm under the impression that it is due to the nature of GSM and that it doesn't get as much distance coverage per tower.
Also, don't forget the further segmentation of the carriers, one of which is how GSM is further segregated regarding the data which is why you wouldn't be able to use a jailbroken iphone for 3g data on T-Mobile.
I can tell you that I went from a steady weight at a 5000-6000 calorie per day diet and about 8% bodyfat to about 30% bodyfat over about 8 years.
The reason for me is that my job used to be so strenuous that the 5500 calorie diet was just enough to maintain my weight. Then I went to college and a deskjob.
I was just used to being able to eat whatever the hell I wanted, and combine that with the fact that I didn't pick my meals (They were tailored for us), it caused me to have some very poor habits.
I just don't buy it or participate anymore. However, I get recorded as a pirate, simply because their sales have dropped and they record a reduction in sales as an increase in piracy.
To participate in the discussion, one would have to believe that Jesus was a god.
Err, no.
If you believe homosexuality is wrong based on the premise that Jesus is God and that the Bible is correct, why would God heal someone whom He felt was an abomination?
It is a perfectly valid question when presented with someone arguing that God (aka Jesus) is against homosexuality.
On the other hand, there's no real ethical or legal excuse for pirating something, simply because you don't like the price of it. If you don't like the quality of the offering at the price it is offered, then don't buy it. It's quite simple
What about me wishing to simply send high definition video and 7.1 audio to the display of my choice without having to purchase 'special' hardware?
It's a bit too late, you missed our generation, and it has already spread to our parents (who are pissed that their TVs now require several boxes and don't just 'work') and our children certainly aren't going to 'rebel' by embracing the corporate message.
The only way to earn respect is by showing respect. And, last I checked, my television/vidcard/cablebox/musicplayer/gameconsole all don't seem to want to trust me or each other. I'll continue to go with the more convenient, fully compatible, more functional, product.
When my iPhone decides it won't try to automatically erase itself after I reinstall my OS, When my cable box outputs an unencrypted signal... hell, when I don't need to rent cable boxes just to access channels my TV can technically display, When I can install a new hard disk in my game console without thrashing the firmware...
Start with that, and then I'll listen again. At that point, then we can discuss some of the other built in annoyances you have contrived.

It's not how much sense you make, it's how "strongly" you feel about it and how loud you can yell. Just like in politics
Really? In that case, $5 for everyone that mods me +1.
Now it's just like politics.
