Next meeting: 31st July (next Monday)

[Duncan Roe]

Hi everyone,

Sorry for the late notice: my system (nvme) disk failed
and my newest backup was 3 months old.

The next meeting is next Monday. I've updated https://mlug-au.org

Right now we have no talks scheduled.
@Danny: Did you say last month that you might have something?
Email me on or off list about that please.

With the crash I haven't had time to adequately explore the Makefile debugger
that I was going to demonstrate, but I also came across some unexpected (by me)
features of the MANPATH environment variable so I could do a
(somewhat shorter) session on that.

Meeting will again be virtual unless there is overwhelming enthusiasm(*)
to meet in the pub.

Cheers ... Duncan.

(*) at least 3 more people sign up on the website (I'm there already)

Coincidentally I recently had a (much smaller) disk failure; a backing
disk for a database had a few dozen bad sectors.

I can give a tour of the ways I probed and "fixed" the problem (without
backups).

"Adventures in database corruption" or something similar?

Cheers,
Danny Robson

interesting - I was thinking about presenting some work I did recently where I was deploying a new system using an ubuntu live cd and ansible, portions of which needed to modify the pre-boot non-functional copy of the OS from inside a chroot in the livecd environment, which might be useful in a rescue situation also ...
