Just a thought, since the phone is a small computer recieving digital instruction... What is to stop there being a law enforcement ovre ride in the tracking option.
You turn it off, but LE can have the phone co send a signal and change the setting. Presto, you carry around a bug.
Cops don't *need* a warrant to observe you. Not even without this. There's never been any sort of protection against observing people.
True but they do need a warant to have your one device spy on you. Example a wire tap. Otherwise they have to do it the old fasioned way and follow you.
This card is targeted to high end users with 6 and 12 Mpixel cameras. They shoot raw images (lossless compression). Very high file sizes are created.
It is not geared to the 2 Mpixel consumer camera which is using jpeg compression. Tarring or zipping jpeg compressed immages would be pointless since the images are ALREADY compressed far beyond what normal compression can do.
Try the Adaptec 2400A ATA 100 controller. It has 4 IDE master ports and works very well under linux. I have had one up and running for 2 years.
Adaptec should be comming out with a Serial ATA raid soon.
when you send data down a wire (copper trace or actual wire) at very high speeds It needs to be treated like a transmission line. The length of the wire and relative speed have to be taken into account.
Basically this means that rather than treating the wire as a fixed capacitance, inductance, resistance, it must be treated as a distributed system. Each dx has a dc, dl, dr. The longer the wire the higher the impedence. Now you have to take into account the bundling the wires ans assuring that they are all equal length and impedence. This is why IDE went from a 40 pin connector to an 80 pin conector. The data pin count remained the same, but the grounds increased.
Next you have to take into account the drivers and receivers. Each has certain variations in their physical properties. Taken as an individual, you minimize the tollerances. BUT when you add many of them in parallel, the tollerances add as well. The end result is that the overall speed is limited due to the summation of tollerances in the wire AND in the silicon. This is physics and no real way around it.
Fibre channel is basically seiral SCSI. Is it gonna make it? Who knows, it is up to the market. I know there is an innitiave toward iSCSI for SCSR over ethernet. I don't believe this is intended to be over the common network on your LAN but a separate one for storage.
I am not an expert on fuel cells or hydrogen, but it is a viable alternative. Fuel cells are steadily increasing in wattage and will soon reach the 200Kw range.
Now all fuel cells use hydrogen. The question is where does it come from. The 3 most common ways are compressed gas as was used in the article, gasoline, and methanol. Methanol and Gasoline both require a reformer to break the hydrocarbon chain an mahe H. Gasoline is a complex hydrocarbon, has an excelent energy density, but is complicated to reform than methanol. It is also supported by a large infrastructure.
Methanol is a simple hydrocarbon that is easily reformed into H. It has approximately.5x the energy density of gasoline. One very large benefit is that it can be generated from local
renewable resources.
Anyway the H is made, there will be side efects. Reforming does produce carbon as waste. It can be captured as a liquid or solid rather than a greenhouse emission. Methanol from plant byproducts has all of the nasty issues of industrial farming.
As a side note: Why is that vehiclo so damn ugly. There are some very exciting EV prototypes out there. At least one does 0 to 60 in 3 seconds.
I do know that Toyota and now Ford are using microprocessors that contain the entire flash image. They have the ability to set a securtiy bit and you will not be able to read it. Maybe you can take the chip off the board assuming you have the equipment to handle BGAs... The micros often are disguised. So when you use IDA, which micro is your target. It makes a difference.
I can't speak to the imports, much. I do know that the increasingly more popular method of relflashing the PCM is through the OBD connector. Take a look at Hypertech or Superchips or Diablo Sport.
And as to how this applies to DMCA, the above mentioned companies DO break seed key algorithms. They do bypass copyrighted security mechanisms.
Really,
Amazing, where did you get your information?
ODB II mandates a common diagnostics interface. The error codes are spelled out in SAE doccuments. They also specify that a seed / key security mechanism or stronger security may be used when it comes to reflashing the PCM. In other words anyone can read the error codes but only the manufacturer can officially reprogram the ECU.
However, dipshit, the ECUs are NOT open source. Sure, if you know what you are doing you can intercept the serial stream, decode the proprietary parts and defeat the seed / key algorithm. Then you can hack the interface. If you are lucky, you can open the ECU, identify an eprom and read the code. THEN you need to figure out what MCU was used, disassemble the code etc. Ok, now where are the variables used to control fuel / air / timing etc?
Next time do your homework.
Oh, Ford is moving to the PPC555 which is all internal flash with security so good luck.;)
I mentioned this yesterday on the DMCA thread. A lot will depend on the outcome of the lexmark case(me thinks).
The ECUs all have security ranging form simple 16 bit seed / key to fairly complex hardware (including analog signals) with complicated pass codes. The companies have definitely bypassed the protection to gain access to copyrighted firmware.
I think the interoperability issue might be a loophole but... As far as the big 3 are concerned, chipping a car raises their profile and gives them some extra free advertising. It is a love / hate relationship.
It depends on the year / manufacturer. Some even have different comm busses across different models. OBD II only. Prior to '96 ECUs were not reflashable.
Ford generally uses j1850 pwm (diff pair).
GM generally uses j1850 vpw (single wire).
Chrysler (North America) may use j1850 vpw, can, ISO9141 or a proprietary SCI protocol.
Toyota uses (at least partly, ISO9141).
VW/Audi (BMW????) does diagnostics over K-line, (ISO9141 or KWP2000). Then they use a proprietary protocol called VAG.
Other Euro cars use mostly can.
Honda???? not sure about this one.
Wether it is easier or not is up for debate. The fact remains that the aftermarket companies prefer the reflash method. Perhaps, because it does not require you to open the hood or lift a screwdriver. You simply plug a handheld into your dash and press some buttons. Removal of the mod program is done the same way for inspections / waranty work.
But THAT is not the issue. The issue is the ramications of DMCA on that industry.
Thera are a number of aftermarket companies who make modifications to the vehicle's stock program to alter its performance. The old way was to physically replace an eprom, or add a "chip". The new way is to use the vehicle's communication bus, pass a PROPRIETARY authentication algorithm, and then reflash the vehicle computer.
In either case, the "new" program fundamentally contains the copyrighted code from the manufacturer plus a few slight parameter changes. And the authentication algorithm was definitely circumvented.
The ramifications for this go beyond the chip companies. Aftermarket hardware such as turbo, blowers, cams, all require changes in the air / fuel ratio or timing to work. They can dammage the car otherwise. With modern EFI this can only be done by modifications to the vechicle's program.
If you can find a surplus 10x or better scope with a light buy it. You would be amazed at how steady you become when you look through it. 10x is not enough to really check for fine hair like bridges but you can do TQFPs and 0402s.
The trick is to use lots of flux. Put the solder on the tip before touching the pin. It will flow like magic. Practice, practice, practice....
FWIW, unemp = unemployment insuance. That is the money you get paid to sit on your ass and work on your resume.
If this guy was unemployed and doing a project like this, kudos to him. If he was a student, or an engineer doing it in his spare time, kudos to him.
And I believe I said I am WORKING. I make MORE than $275 a week. It is the fact that I do projects that enables me to keep my skills up and quickly land on my feet whe the market softens.
This is my first post on/. because this touched a nerve.
I am a WORKING hardware engineer. Currently I am programming a Xilinx Spartan II XC2S100 FPGA in VHDL. This week I am "learning" VHDL because my primary HDL is Verilog.
As to the value of this skill, one of my very good friends is a member of the Xilinx Xperts program. He is a paid consultant and makes serious $ hourly. Companies kiss his ass just to get him to come work and get them out of a jam.
Now, I have been laid off from a major hardware vendor in the server industry. Me and about 1500 others. In case no one noticed the industry is still somewhat depressed.
Looking for a job... Get up, check the paper, monster.com, etc. Make 20 phone calls, email 20 resumes. This is usually done before LUNCH.
I spent the rest of my time doing neat projects. Polishing my verilog skills, doing anything to keep close to technology. This project is cool shit.
Even now, I have 3 projects going. It always pays for hardware engineers to keep on a wide variety of technical designs. Otherwise you will get fat and stale. That can kill a resume.
Oh, for the record unemp here is $275 a week. See how far that goes when you have to feed, dress, and provide health insurance for 2 children.
