comment How can I destroy data on a failed hard disk without voiding warranty?
@JoelCoel: No, that's not true. If the drive is properly encrypted, a brute force attack is (phyically) impossible - see e.g. Amount of simple operations that is safely out of reach for all humanity?. Of course, there are a lot of mistakes you can make when encrypting things...

comment Is there a way to provide user-specific passwords for Wi-Fi?
The captive portal is something to consider. However, note that captive portals usually authenticate by the MAC address once you are logged in, so this is just a more sophisticated way of setting up MAC filtering.

comment Should Carrier Ethernet traffic be encrypted?
Also, even if you have "full and sole control" over the hardware, it will be difficult to enforce it. You cannot patrol every meter of a kilometer-long cable.

Also note that accidentally logging in to the wrong site is rather likely in a "foreign" network, because intranets often have some hosts that use "generic" hostnames like www, wiki, mail etc. For these names, it is quite likely that they will exist in the foreign network, too.

Note to self: Another interesting paper on latency: Latency in HSPA Data Networks, Qualcomm.

Thanks for the information, very interesting. Since not everyone can read the book (and since answers should stand on their own): Could you explain a bit more how TCP slow start, radio controllers and configuration contribute to latency?
