comment Can Ubuntu Desktop “become” Ubuntu Server?
Note to anyone visiting this page: this answer is wrong. Firstly, it's easy to change kernels. Secondly, there are no longer separate kernels for server: linux-image-server is now just an alias for the generic kernel.

comment How to minimise SpamAssassin (spamd) memory use
From my observation and using the tool smem, it looks like spamassassin uses around 50 MB of RAM, and that if you fork it into multiple processes, almost all their memory is shared memory, so it'll still use around 50 MB of RAM total amongst all processes, even though ps reports each one having a RSS of 50 MB. YMMV.

comment Recommended DNS SOA record TTL default?
To clarify, the SOA Minimum TTL field stores the TTL value to be used to cache a negative request - a request made to the zone for some resource which doesn't exist. Their explanation is sort of true but fails to clarify it's only for negative responses. Secondly, the SOA Refresh is never used by normal DNS queries, it's only used in situations where you have secondary (slave) nameservers updating themselves from your primary (master) nameserver. So their explanation of that field is definitely untrue.

comment Why should one have a secondary DNS server?
I've read quite a few comments that indicate that many real-world DNS caching services (like those used by ISP) don't re-try using a second name server, they just fail if the first server doesn't respond. For example, this answer on serverfault. In which case, if you have two separate nameservers you need to make sure both are up, because either one being down can lead to downtime for the hosted domains. This does go against common practice and the RFCs, but seems concerning.

comment Should I use .htaccess in an Apache production/live environment?
Whether it is in the source code and whether the impact is significant enough to be measurable are different. As we're talking about read-only access, this should be entirely satisfiable from the system cache once it's read in the first time, shouldn't it? If so that would eliminate physical disk access. The rest is in-memory and not very strenuous.
