I don’t spend much time on @bsky.app & mainly cross-post from Mastodon 🐘. But, if you follow @ap.brid.gy, you can bridge your account & let people (like me) follow you from the fediverse, which is very cool.

A strange thing happened today. I wrote a to-do list this morning and, by the end of the day, had ticked everything off. My inbox is also empty.
I’m not entirely sure what to do with myself.
Presumably I’ve forgotten something important.

Each of us has a dream,
a heart's desire.
It calls to us.
And when we're brave enough to listen,
and bold enough to pursue,
that dream will lead us on a journey to discover who we're meant to be
There’s nothing quite like Happily Ever After :MickeyHeadOutline:

A moderately productive weekend of #DIY : installed an outdoor camera, routed wiring through the loft, replaced a single socket with a double, and spent more time than planned on ladders and crawling through insulation.

It’s not often that I give up on a book, but I’m 100 pages in and this really isn’t for me. It’s a real shame because I was really looking forward to this one. #bookstodon

I’ve got my eye on a new #aquarium . Does anyone have any experience with #fluval #roma ? I am just looking for a tank and light, but it seems that full packages seem to be the best value. I don’t need the filter or heater, so I will probably sell those on. #fishkeeping #fish

Tomorrow is my first completely free day in as long as I can remember: no work, no children’s activities, no parties, no travel.
Just rest. Possibly silence. At this point, sheer momentum is doing most of the work.

Already a busy weekend: eldest’s #SchoolLeavers Mass and party yesterday; two #dance performances for the youngest today; then #GrassrootsFootball for the eldest and a birthday party for the youngest tomorrow.

I *may* have wandered into our local fish store this afternoon. I *may* also have bought more #fish .
On an *entirely* unrelated matter, please meet Kung Fu the Panda Cory 🐼. I haven’t had chance to think of suitable punny names for the rest of the school yet. :seas:

On the train to Edinburgh for a meeting of the ICMS Programme Committee.
Lots of interesting proposals to discuss. Coffee in hand, which is doing the heavy intellectual lifting at this stage of the journey.

For years my #Mastodon database backup strategy was nightly pg_dumps, which worked perfectly well until I started thinking about all the ways this could fail.
Now #PostgreSQL is backed up properly with #Barman : base backups, WAL streaming, retention policies, and off-site storage over WireGuard.

I need to go for a fasting blood test today. I can cope without food. Coping without coffee, however, is beginning to feel less like preparation for a blood test and more like a character assessment I did not consent to.
