... While he seemed to be discussing only charges between ISPs to deal with their costs of routing traffic for each other, the discussion took on a more general tone, discussing whether or not flat rate was good or bad. Arguments in favor of flat rates were bandied about. ... I tend to agree that flat rate encouraged these services, and that in general that flat rate encourages use (and therefore, innovation), whereas metered rate discourages use. ... See how good flat rates are? ...

... The star formation rate (SFR) of the current SF episode can be estimated from the total H luminosity. ... For the derived total flux F (H )=5.8 erg s -1 cm -2 we obtain a total H luminosity of 10 39 erg s -1 . ... The total mass of ionized gas can be obtained from the average mass density inside the H II region and its volume. An average mass density corresponding to the average electron density of 1 cm -3 within a volume with a diameter of 0.5 kpc yields a total ionized gas mass of 10 6 . ...

... Re : Can you block or ignore ICMP packets? ... While adding that #define CONFIG_IP_IGNORE_ECHO_REQUESTS into linux/net/ipv4/icmp.c will work fine for now, I'd suggest putting it into the configuration-headers so it doesn't tangle up with further patches, or, should that define later move into different file(s), lose it's efficiency. ... Meanwhile, if you're worried that ignoring _all_ echo-requests may be a bit too rough move, there's a way to make the kernel ignore them selectively. ...
