Weather forecasts have become much more accurate. A four-day forecast today is as accurate as a one-day forecast 30 years ago.

This image shows the hourglass shape of the nights shortening and lengthening from winter to summer and from summer to winter, passing clouds, the Moon passing through the night sky every month (diagonal bands) and the Sun climbing higher in the sky during summer.

For the 4th year in a row, my all-sky camera has been taking an image of the sky above the Netherlands every 15 seconds. Combining these images reveal the length of the night changing throughout the year, the passage of clouds and the motion of the Moon and the Sun through the sky. #astrophotography

Writing bash scripts in ${CURRENT_YEAR}

Still can't bring myself to `rm` my tempfiles

You never know when a cosmic ray will strike the memory containing your $TMPDIR and turn your `rm -rf ${TMPDIR}/var` into `rm -rf /var`

The paranoia is real!
I'll leave cleaning up /tmp to a system service!

Wow, people using BlueSky's Open Network in their own apps to do add discussion threads to.. anything!

This is the sort of global database that Blockchain promised to be, without all the dodgy crypto and high energy use of existing Blockchains.

It's #SC24 week, so what better time for the Bristol Centre for Supercomputing (BriCS) to assemble the 5MW data centre for Isambard-AI. Of course we have typical UK winter weather to contend with, i.e. wind, rain, and today even snow. Fantastic support from HPE and Contour makes this possible #HPC

Thank you for all for blowing up my phone with New Follower notifications!

I plan to start sharing lessons learned in HPC, Cloud Native, Linux, but also considerably less sexy stuff such as documentation & project management approaches.

There, I can't take it back now!

IMO Twitter has ceased to exist, which means "Tweet" is up for grabs as a common verb!

Looking forward to Tweeting across the fediverse!

I dropped Twitter over a year ago now, between the new owner gutting the staff, scrapping safety teams and vocal intention to flood the user experience with junky cash-grab features, which all pales against the dodgy stuff he spouts about conspiracy and defamation.

I didn't want my name attached.

I'll never forget our Unified Model / NEMO team being surprised that their codebase... compiled!

They expected it to be wrestling through build errors all day!
Isambard helped prove the GNU/Clang/Cray stacks were supported without too many major caveats beyond a different ISA.

GW4 Isambard 2 officially powers down after 6 years of service and innovation - GW4 GW4 Isambard 2, one of the world’s first Arm-based supercomputers to go into production use, has officially powered down for the final time, after six years of service.

It seems like #SC24 is a popular time to not only announce new supercomputers, but decommission them.

In addition to Summit's farewell party this week (after six years of service!), Isambard-2 is being retired after 6 years as well: gw4.ac.uk/news/gw4-isa...

OK, let's try this to show the HPC community already has momentum and can thrive here on Bluesky ...

I've developed a pleasingly simple interactive Bash script template over the years, I need to do a write-up explaining it

Bash has such a long legacy some sysadmins will account for issues that have been long solved, or conversely use syntax that hasn't been necessary in well over a decade.

When you've invested too many hours in a platform before you realise it uses JQuery...

Worse that, the JQuery is introducing a 2 second rendering delay... and it's woven into everything so I'd have to rewrite ... Ugh Javascript.. to fix it!

My disappointment is immeasurable, and my day is ruined

BlueSky lists has really helped turbo charge my feed back to what I used to enjoy on that old website, "Twitter"? Was it?

It was like MySpace but less poorly compressed wav files.. and no custom background images...

Anyway, I'm glad to see my tech people tweeting again!

Wow, so all it took for people to try a new social media platform was realising they were accidentally fueling a crypto-fascist movement, oopsies!

Hello πŸ¦‹

Happy to see many familiar faces around. Wasn't easy to find all of you (I probably missed many), so I created a starter pack to make it easier to (re)connect and nerd out about distributed systems, programming languages, and container stuff. Let me know who I missed!
