... 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. ...

... PPTA timeline . ... List of projects . ... RedGW . ... One of the main goals of pulsar timing array projects is to limit the existence of a background of gravitational waves (GWs). Jenet et al. (2006) developed a method to determine such a limit if (and only if) the pulsar timing residuals were statistically white. In the paper we used data from six pulsars from the PPTA project to obtain a limit. The remaining pulsars were rejected because their timing residuals were not white. ...

DISCLAIMER: The larger the aperture, the more light a telescope will gather and the fainter the object you can see. Here is a range of magnitudes you might expect to see. Given excellent sky conditions and good optics, a well trained eye can sometimes add up to 0.8 magnitude to these values. Limiting Magnitude depends on much more than the instruments aperture. ...
