OK, the queue of US carmakers outside the Congress grows again, and these idiots continue to advance a car with specs that no-one except a green millionaire would want to buy (because it is his 5th car).
To be useful you need 140 KPH, 500K range, 1 hour service time. If they cant produce that (a) dont give them any money, it will be back to 7l Surburbans in 6 months (b) fire the CEO; otherwise the far-east will eat your lunch in the up-turn.
First CD and DVD, including BlueRay, HD, are very different. The CD hardware layer is hugely redundant with each 8-bit byte being written as a 14-bit forward ECC block and each 2048 bit sector is protected by a Cross-interleaved Reed-Solomon code in 304/2048 bits ie hugely redundant. See the Sony/Philips rainbow books.
Thus unreadability means gross damage, dye decay, scratches or thick dirt. Physical scratches/dirt can often be recovered with very fine metal polish and wash. DVDs are _much_ more iffy. A few readers let you read all the 2352 mode 2 data bits of a data CD but most dont and you cannot detect 14 2 8 bit correction which is the first indication of the dye degrading. If you store the CDs in the dark, in scratch resistant envelopes in a strong box you have a good chance of 20+ years. I wrote the one of the first Philips writer drivers and have CDs that old.
Otherwise you are down to replication and data washing, but dont throw the washed CDs out!
Having just spent about 18 months working with highly clustered HPC the answer is your milage will vary. On your own laptop, even dual core, this is a silly idea, encrypt just what you must and de-/en- crypt it once as part of the JOB; no on the fly especially if your problem uses n000 giga-bytes of data; in an RDB encrypt just the appropriate column. E.G. if, for patient data you encrypt the Name/Address... you have (a) anonimised the entire data-set and you probably have (b) zero processing cost.
En/De- crypting cell data for the Gas or Elasticity equation or the intermediate results of a stochastic process is a waste of time.
If you are into heavy-metal c 1000 Barcelona level cores, then your storage architecture may/will be doing its own thing and that may encrypt everything but with such an architecture that will be done in the DISK CONTROLLER not the application CPUs.
The point is (a) if you travel, or (b) you have some sensitive data on a mobile device _DO_ encrypt it --- it will save you and your organization from much cost and _egg_on_face_.
I have now heard enough comments on the mis-behavior of many large company SUPPORT and HELP-CENTRES, the solution is to issue the writ, in local court first.
No call centre guy wants to responsible for his company failing to answer a writ!
The reason that personal information is so important today is the lack of proper and safe authentication, in the digital age and the culpable failure of law-makers and business to insist on a secure way of authenticationg anything beyond a (witnessed) signature.
I dont care that my social security number, address or phone number is public; I do care that this information can be used to impersonate me, and after that neither law-enforcement or business cares at all; and I get stuck with reverse-proofs in a legal system that barely works.
The cure is to put the onus, and loss, where it belongs, on business; and set a sensible minimum standard for digital authentication i.e. adaquate X509 or PGP keys.
Normally I would agree with you abou the obsession with safety,
but, the problem with the Shuttle is poor engineering, bad engineering management and excessive CUA by beaurocrats whose only risk is that the public will wake up to their repeated failure, and exactly the same thing comes with most military procurement.
The fix is fire the NASA __Management__, and appoint someone like Bert Rutan or Richard Branson.
This is the most stupid use of Federal Intelligence and policeing ever;
One must assume that the politicised senior executives have not the wit to understand the benefit of timely disclosure of security exploits and the fact that the black hats will know without public fanfare.
The FBI and the DHS have a job that SLOULD fully occupy them, find Ussama bin Laden, and kill him. When they have done that they can turn to lesser priorities.
the entire reason for the shuttle was to make frequent, 3 x weekly, launches, which it has never done!
The design is a failure, that much is obvious, what is not obvious is hou long the oversight, which should come from the Congress will let this waste of taxpayers money coninue.
Is it not clear to everyone that these vehicles are a DEAD HORSE and that they, and most of the NASA beaurocracy and engineering going on into this is about as fruitful as flogging that dead horse.
Why does the US seem unable to deploy the expertise that it has and spend these research and devopment funds wisely,
all the existing crew seems good at is dreaming up slogans:
RETURN TO FLIGHT --- nonsense
Abandon this mess, and find some good engineers, fire the spinners and apologists!
Along with Linux, the biggest competitor to M$ is old M$ systems which do not get upgraded.
Every time they do something like this they hurt themselves more, but as a Marketing company they _cannot_ admit this, and that is a huge clueless weakness.
No, the root of all evil it the UNCRITICAL acceptance of (a) strong typeing, and bending the language so that a compiler can, always, and theoretically, detect mistakes at compile time instead of warning and interpreting as CPL, ancestor of BCPL, B, C, C++ tried to do, but, of course warning and checking at run time, and (b) the fact that new developers are taught that a single paradigm, procedural, functional or OO is not only a GOOD_THING but the ONLY_WAY!
This leads to the pure Java mantra, "Perl is write only", you can't write OO code in C and a lot of more nonsense.
Like many others, I need to remember lots of passwords, including lots of root passwords to SSH into machines; so I have modified SSH so it will decrypt a file containing tripple machine -- user -- password, given a master password, which happens to be my root password and that for a 'gringotts' file of all other interesting secrets so I only have one password to remember, and change so I commend the 'gringotts' approach, also available from Schneier PasswordSafe? for Windoze.
You do have to copy the files to a CD or floppy and put a post-it note on it in case you get run over by a bus!
Compare and contrast DARPA, which founded the research to build the internet,
and what is happening in the post 9/11 chaos,
one was engineer led, the other opressive and much more importantly, completely inefective.
Someone, in the US space, needs to start asking serious questions, so security policy is made by scientists and engineers, not politicians, whether elected or not. If US military-industrial waste is allowed to continue, in this failure mode,
Usama bin-Laden will get another chance, and will do _more_ damage the next time.
No, this is not flamebait --- it is clear common sense and directly in line with the legal theory behind both patent and copyright, where the benefit is granted for the _long_term_ benefit of society,
not so a corporation has a licence to print money, and rip their customers off.
If you are a corporation, committed to evil, as M$ is please do not be surprised when marketing turns technical sanity into a pretzel;
The message you are intended to take, from this, if you are smart is __UPGRADE__ since w2K is dead,
if you are smarter, use this as a poster child for why M$ is not to be trusted as a business partner, and move your servers to Apache, and your clients to Firefox,
then migrate all servers to Linux, carefully and cautiously, and forget about crashes and reboots.
This kind of copy protection is usually full of shit; if you look at the CD spec, you will find dozens of different formats + lots of ways of of using the P,Q...W sub-channels in non-standard usage _but_ the cheapo cd-player firmware usually assumes a (final) TOC with CD-DA tracks without mute in Q-subchannel. as its world.
If you read a CD on most burners you can get (a) all TOCs + the complete interim track table (b) the write calibration data (c) all track data (d) all sub-channel data for each track (e) inter track + inter session, ie lead-in/out
data (f) ATIP data (absolute time in pre-groove)
With this you can ignore the junk, and just rip the audio data you want, and usually it is trivially easy ie set session/track/mode read data
and then re-write that data as a vanilla CD_DA track, withoute mute.
If you read what was actually said, most replies make no sense; to paraphrase:
Mainstream developers, using common architectures, which will change over time, should not hold themselves hostage to proprietary, minority or legacy platforms... and lack of platform access makes this impractical in any event.
This makes complete sense, if, as is actually the case HP, IBM & SUN have, by incompetance or greed, placed themselves in a position where their platform _depends_ on GNU tools they need to spend some support revenue on the tool-chain, and provide gratis platform access. This is how it used to be before Red Hat bought Cygnus.
Finally, no one is going to deprive legacy platforms, they have to do work, pay or resign themselves to a feature freeze.
