Why don't they make HDDs and platters like this?

When I did electronics at university SRAM was much faster than DRAM and
you didn't need the refresh cycles. Have things changed? They are larger
(physically) and more expensive because each cell uses multiple transistors.

Indeed wikipedia hashttp://en.wikipedia.org/wiki/Static_random_access_memory

Characteristics
SRAM is more expensive, but faster and significantly less power hungry
(especially idle) than DRAM. It is therefore used where either bandwidth
or low power, or both, are principal considerations. SRAM is also easier
to control (interface to) and generally more truly random access than
modern types of DRAM. Due to a more complex internal structure, SRAM is
less dense than DRAM and is therefore not used for high-capacity,
low-cost applications such as the main memory in personal computers.

Data remanence is a problem that affects SRAM more significantly and
longer than DRAM.

Capacitor-free DRAM is the best for preserving your privacy.

You can have one anytime. Just use a linux live CD system with no hard drive.



Linux live CDs do that fine.

Is Linux live compatible with currently-available laptops? If so, will
the CD work if I remove the laptop's HDD?

If this works, then part of my problem is solved.

Then next obstacles are figuring out how to keep changing the MAC
address and finding a wireless internet hotspot whose IP address is
dynamic.

Oh and another hurdle is to make sure the laptop uses capacitor-free
dynamic volatile RAM.

CFDVRAM poses the least risk of data remanence.

Yep, completely trivial to do that.
What if I use a wireless router that is powerful/sensitive
enough to communicate with internet cafes at least 1/4 mile
away from me and the IP of the cafe is dynamic? Am I safe, then?

Nope, because it still ends up coming from that cafe.
The new IDs will keep getting useless to them each time I turn off my laptop.
Not when they keep track of the new ones every time your turn it on again.
They can keep track of the MAC addresses, but how do they know the
source of them if I can simply produce random new MAC addresses
[and get rid of the old ones] -- which is what I was thinking of doing?

They can do it by content analysis too.

Its completely trivial to work out that its you again from the content of the shit you post.

Thats not that hard. Corse I cant tell you how to do that because then I'd have to kill you.

Wont save your bacon even if you do find one.

Its pointless bothering about that, they'll do you on the shit you dump into the system.

Wouldnt save your bacon even if you did find a laptop with that.

Data remanence is a trivial part of your problem.

But it will still be difficult to find me considering that so many
people are using wireless internet hotspots at a given time. Right?

Why would you have to kill me if you told me how to continuously
change my MAC address?

What if I keep changing my writing style? Wouldn't that make it more
difficult for content analysis to figure me out?
