Re: Flash wear
Yep I've seen a good number of failed firewalls after logging was configured to store on the local storage after a couple years. Never used to happen when you had real hard drives inside the firewalls :)

Err do I know this person? Did exactly the same on an IBM 4Mbps Token Ring (TOKENLINK III 16/4 3C619B cards if my memory serves me correct). In Novell Netware you could run a command to view local PCs (like net show in Windows) and after a while it'd come back and you'd only see the PCs that were playing DOOM :)
Two stories I'm sure I've mentioned in these halls before with interference:
1) Our CEO many moons ago had an apartment in Paris and used to moan that his WiFi (original 802.11b) was unreliable, even after purchasing a full blown outdoor antenna, complete with lightning arrestor. I told him he was talking rubbish so he shipped me out there on the EuroStar and to my astonishment I could stand at the end of the corridor looking at this massive outdoor antenna mounted 5m away at the end of his hallway I lost my signal. Turned out he lived under half a mile from the Eiffel Tower and as you stepped into the hallway where a large floor to ceiling window showed off the Tower you immediately lost all WiFi. The Eiffel Tower was spewing all sorts of EMF. The CEO later told me taxi radios didn't work round here either amongst other weirdness. Ended up putting Wifi repeaters in every room of the apartment.
2) We moved IT into a new office and I kitted out the place network-wise and I also put up a dozen large LCD TVs for various monitoring uses. These TVs used HDMI over CAT5/6 and were SO unreliable it drove me almost mad. They used to blank out all the time at random times. It turned out after one late night working on the screen resolutions, refresh rates and so on that a cleaner walked in and the TVs that had been fine for hours suddenly all blanked out! It was the IR sensors that kept the lights on! Whenever it detected any movement, it send out a load of EMF radiation that messed up the HDMI over CAT6. Had to replace all the cabling with shielded cabling and then it was fine.

I did the same while sitting in c:\win31 on my dad's IBM 386 PS/2 P70 luggable he'd brought home for the weekend. Undelete saved me, but you had to supply the first character for every file (in DOS 5 anyway) so it took a lot of slightly educated guesses to get Windows 3.1 up and running again! This would have been 1993 ish and a very happy 13 year old I was when I got back into Program Manager!
I have a right mix of smart tech at home, but my Z-Wave stuff is still working fine too. The controller is cloud based but runs happily locally if it loses Internet connectivity, and I'm pretty sure the company has vowed to open source their software should they ever go bust.
Ah Packeteer's PacketShaper appliances were the nuts! I loved them too. I remember being impressed by the fail-safe failure mode where the appliance just basically turned into an RJ45 connector.
Just Googled and now it's all owned by Symantec (via Blue Coat) so that's sad :(
