Tech updates: reducing storage writes from logging, slow random.

I'm trying to concentrate on my shiny new research work, so this month has been mainly reactive.

2023-03-18: random.hd.org

As of today, random.hd.org is back and running, after a fashion!

2023-03-06: Catchup

Some simple housekeeping today, while stuck in bed with a resurgence of an annoying cold...

I realised that I had not updated the by-year meter readings table in the overall "saving electricity and gas" page to move to 2023. Now fixed. (I also updated the thumbnails to the latest snapshots.)

I realise that this could probably be an automated page insert now, but to avoid adding another moving part to be maintained I'll probably leave it as-is.

2023-03-05: Syslogging Less: BIND

Having turned down mail logging, other nonsense became more visible.

I have now turned off a lot of BIND9/named log entries of the form sencha named[NNN]: network unreachable resolving 'nnn.nnn.nnn.nn6.in-addr.arpa/PTR/IN': NNNN:NNN:N::N#53, by adding the OPTION -4 (IPv4 only) in /etc/default/bind9.

2023-03-04: Syslogging Less: Mail

There has been in my to-do list for a while an item to reduce logging from mail (via syslog) in particular.

Now done.

It looks as if SPAMming attempts over the last few days at least were nearer 4,000 a day than the historic norm of ~10,000 per day.
