If you have solved your problem you should answer your own question and then select ("check") it as the best answer. Answering your own question to complete it is perfectly acceptable, even encouraged (when a *better* answer is not available). See Jeff Atwood's [se] BLOG 01 July 2011 [*It’s OK to Ask and Answer Your Own Questions*](http://blog.stackoverflow.com/2011/07/its-ok-to-ask-and-answer-your-own-questions) or the end of this *[faq#question]* section.

comment Fast Way to Randomize HD?
@Gilles Also, even if it would work, openssl rand is still too slow on my admittedly "ancient" core 2 duo desktop. Piping openssl rand to the stdin of dd appears to fill the drive at around 30 MB/s. If I instead use if=/dev/zero on the dd command I get (initially) around 150 MB/s. Drat. (But of course that is still much better than /dev/urandom. ;-) )

comment Fast Way to Randomize HD?
@Gilles The problem I ran into in Ubuntu 13.10 is that openssl rand seems to have an upper limit on the number of bytes it will generate. If you exceed that limit, e.g. 'openssl rand 810000000000`, then no random output is generated. Only a brief "help" text is printed. I'm trying to random (pretty much) fill a 3TB hard drive. Not sure if there is a way to get openssl to produce that many random bytes.

comment lshw and lscpu disagree on caches - which is right?
@Raphael I don't really know why lshw returns the cache results it does. But possibly they didn't want to change their output format out of concern they might break a script that parsed their output. You can paint yourself into a corner all too easily with software tools.

comment lshw and lscpu disagree on caches - which is right?
@R I was not aware you were (still) looking for something. Frankly, the problem I usually have with Intel is that is too much information provided. What sort of info are you interested in? Looking to the right on the Intel i7-920 page you'll see Quick Links. The datasheet link takes you to a Technical documents page. There are two volumes on the i7-900 processors before they even list the mechanical & thermal specs. Software developer mans on another page. Too many to list.

Used markdown to clean up the links a bit. Added the diagram from the link because the quoted text refers to the diagram.

Pity we didn't think to try running fsck just to see what it would come back with.

You've still got me wondering (1) what the heck got written to that directory and (2) how it happened. Oh, well.

comment “Destination Host Unreachable” when pinging wireless router
You have not provided any information about your environment. Are there other wi-fi access points? Are there any possible sources of interference such as a microwave oven or a non-DECT 6.0 cordless phone? (If I want to blow my wi-fi connection away all I usually need to do is pop something into the microwave.)
