comment Do partitions on SSDs map to physical addresses? 2
Actually, on a modern HDD the mapping LBA -> physical sector is also variable. For example, if the drive detects a bad sectior, it will transparently replace it with a good sector (on the next write); this is known as "sector remapping". I believe in (very) old HDDs the mapping was fixed, as you write.

comment BIOS continuously pressing a key internally filling keyboard buffer
@Pacerier: You could just remove the keyboard. While this requires some disassembly, on most laptops it's not terribly difficult.

comment How to do secure erase of CF card over USB in Linux?
@D.W.: Yes, that is true. However, accessing bad or remapped blocks requires some technical investment. You will have to replace the the card's firmware with a hacked version (if that is possible), or directly access the flash memory chips. This probably involves soldering and intricate knowledge of the card's internals. Very probably doable, but definitely not for a few hundred dollars. The CIA will most likely be able to pull it off - a nosy person poking through the card, most likely not.

comment Is there any software to analyze and detect 'fake' hi-res images (TIFF when really JPEG, deliberately upscaled images)?
Just a note for GIMP users: GIMP also supports LAB mode; it's under "Colors / Components / Decompose... / LAB".

comment How can I download the certificate of a wireless AP using 802.1X?
Thanks for the detailed writeup. It sounds a bit complicated; but if that's the simplest way to do it, I'll try.

comment Make wpa_supplicant ignore server certificate trust
It should be pointed out that doing this can be a major security risk: When using username/password authentication, the client will broadcast its username and password to any fake AP, making them easy to harvest.

comment Accidentally deleted files from /boot
@user3109672: Just dowload one :-). The installation CDs of most Linux distributions also work as rescue CDs - ideally use the CD you installed from (or re-download it). Failing that, use any modern Linux rescue CD, for example Knoppix.
