University of Toronto ☛ Lingering bad DNS traffic to our authoritative DNS server
The rejected DNS queries we're seeing so far are a mixture of three types of queries. The first sort of query is for one of those DNS zones that used to be pointing to us but haven't been for long enough that people's DNS caches should have timed out by now. My best guess is that some systems simply hold on to DNS nameserver information for well over any listed TTLs for it. The amount of these queries has been going down for some time so it seems that eventually people do refresh their DNS information and stop poking us.
Pi My Life Up ☛ Checking what Raspberry Pi Model you are using from the Terminal
While checking what Raspberry Pi model you have is pretty easy if you have physical access to it, that isn’t always the case. If you have installed the Pi in a hard-to-reach position, you might need another way to check which model you are running.
This guide will explore one of the easiest methods for determining the exact Pi model you are running, without physically inspecting it.
APNIC ☛ 21 years and counting of 'eight fallacies of distributed computing'
You’d think that by now, networks were well enough understood that people would stop making assumptions that we have known, almost since the dawn of networking, to be untrue. Yet as users, developers, and network administrators, we still seem curiously unable to let go of long-held beliefs.
Perhaps the best-known collection of mistaken ideas about networks is the eight fallacies of distributed computing.
