Fuel stations in "older europe" Please Take Note. In a station deep in rural Poland, I can charge at any table (and Yes, the sockets are actually under power)

Warm day, sitting in evening-shade. Just had a rabbit hopping up to me. At abt 2m it realized "oops, a human" and turned around....

Sitting in a metal barn, just underneath that big red Thunderstorm area W of Middelburg. Noise ! But the wind and rain are very welcome after the heatwave-days we just had.

It worked on my machine... Not even the in/famous "rosetta warning." Thanks !
Smooth. 
Not even rosetta required.Yep. 
First test Positive: it took my additional pluggable databases without blinking. 
ORCL is there for historic reasons. Nowadays, I either add pdbs or services names ORCL and FREEPDB1 just about everywhere...

Fixed by AI: Custom software stopped throwing errors in the category "Exception"... AI-supported developers laughing their heads off: The silly human had a query : reason like 'Exception%'. Hence Easy to eliminate those Errors...

Brag moment: new macbook isnt quite quite top-of-specs (M5pro, not M5max). But the extra money for nano-texture screen makes this 1st laptop I can truly use in garden. Let s see how she holds up...

Who else gets a small kick out of running xeyes.. kids loved it 20yrs ago and still.... In my case, on a container-image, enabling it was... # dnf config-manager --enable ol8_codeready_builder # dnf install xorg-x11-apps

hey, Can Never Resist a new Toy. I got it (downloaded, X11-installed...) Then tested it (trivially....) Sometime I feel like holding a shiny new tool, looking for a use-case. Will try more when time... Nice job by @toonkoppelaars.bsky.social and @chrisrsaxon.bsky.social

I suddenly have a much higher opinion of ChatGPT..

Piet de Visser @pdevisser.bsky.social · 29/08/2025
ZeroGPT agrees with Timor, but ChatGPT leans to "human".. I'm neutral.. a lot of medium etc, especially when the topic is AI, smells "marketing", "clickbait", "must-produce-for-boss". A lot is just BS.. But even in the BS there can be some nuggets.. lot of AI is trained by BS. AI-in = AI-out.

Thx! my test in screenshot. pl/sql funct and sql-macro. col1 and col2: funct-calls. col3: sql-macro col4: systimestamp. Note how the function-values vary, increase, per cell, and start slightly newer than the systmst and sql-macro. Macro is atomic and == systimestamp. maybe blog soon.

Data-processsing the #SmartDB way. Any processing that can take place "inside the database" should be done Right There. Bring your code to the data, do not drag the data out to the code.

You just "invalidated" a series of my test-cases, some dmp-files going back as far as 90s and v8.1.7. Unsable on Autonomous. But I could still import one into 23ai (free-version 25.7.0.25.01)(docker image from @gvenzl.bsky.social ) Have to revert to SQLcl and/or dp for saving testcases.

All Good Answers so far. Thx! Specific case: q+d test where python-function spits out mystats after each test/loop/run, in style of autotrace (screenshot). Those nrs accumulate in session, unless either re-connect, or subtract, or ... re-Set => 0. okok, I may code a subtract. #instrumentation
