comment How to delete all hidden files and directories using Bash?
Be careful with that shorter version, it will give similar, but not identical results. It won't match names with two dots at the front (e.g. ".../" which is sometimes seen hiding rootkits, etc.)

comment Making hosted applications resilient to BGP failures
Be wary of providers that will "cough up" a /24 or /23 of address space based on how much you are spending rather than demonstrable need. Chances are they are breaking the rules that they agreed to when becoming an LIR. Provision of Provider Independant address space is out of your service provider's hands. AFAIK no RIRs will make a PI assignment based on invoice size...

Previous comment should have read the IEEE have never standardised Jumbo frames. IETF have no remit to mess with the 802 standards...

comment What IP MTU sizes are seen in real networks
Jumbo frames of 9k are quite common in datacentres, especially if there are NAS devices present. Some ethernet vendors support jumbos of higher than 9k (largest I have seen supported is 15k) but 9k is the largest that is likely to be seen cross-vendor. Even the 9k figure varies from vendor to vendor (e.g. 9000, 9192, 9600). The sizes vary from vendor to vendor due to the fact that the IETF have never standardised Jumbo frames. The 802.3 standards all give 1500 as the largest supported payload.

comment Do entries in local 'hosts' files override both forward and reverse name lookups?
I haven't had a chance to look at the source yet; however a quick look at ldd output shows that on my system ping is linked directly to the libresolv DNS resolver library, which could imply that it is bypassing the nsswitch file and doing its reverse lookups directly...
