A pendulum! This jogs my brain to an apparently-random #memory, likely from #JamesBurke's #TheDayTheUniverseChanged series, about how #latitude was easy to determine via the skies, but that #longitude could not be measured until timepieces that did NOT require a #pendulum to drive it were invented.

Pendulum movement isn't very functional on a rolling #ship, after all.

And at that moment, the name of the item
I held and it's purpose snapped vividly to mind: it was a #sextant!

Was talking memory with a friend recently and mentioned SDAM, Severely Deficient Autobiographical Memory, that they had never heard of. Another poll friends.

Mondlicht,
schau hinauf in das Mondlicht,
geh' ins Land der Erinnerung,
auf der mondhellen Bahn.
Und wenn du dort erfahren hast,
was Glück wirklich ist,
fängt ein neues Leben an.

(Teil einer dt. Übersetzung)

Mit diesem wundervollen Song aus dem Musical Cats
wünsche ich euch, ihr Lieben, 🧡
einen schönen Abend und später eine behütete Vollmond-Nacht
mit Nähe, Wärme, Liebe und wundervollen Träumen! ✨

Just a random thought: right now, running LLMs on the CPU is slow because of the bottleneck of bandwidth between RAM and CPU. Wouldn't that be less on X3D CPUs where there is a buffer of high speed, low latency memory at the CPU if we use the 128MB CPU cache and use multicores to handle the memory to cache loading and offloading? Isn't that what Strix Halo is doing by bringing memory closer to the CPU and quad channel?

I'm sure there are other technical improvements but wouldn't this make X3D CPUs also better for LLM loads?

Mum said she thought Dad might have a new girlfriend. He hadn't visited her in "hospital".

Mum has #dementia. Dad died 25 years ago. They were happily married for 45 years. (This challenging conversation had a very positive outcome.)

Mum repeated this girlfriend thing a few times and I resisted the obvious head-on factual approach and was replying "Dad wouldn't do that Mum".

Mum wasn't retrieving #memory from the "right" time. I wondered if a different hook might help.

I asked Mum, Do you remember when you last saw Dad? No. Do you remember Dad at home in W---? Yes! Do you remember Dad getting sick, having treatment and you working hard looking after him? Yes! And then he went to ---- Hospital? Yes! (Mum and I came up with the hospital name simultaneously.) And Dad died? Yes.

I saw the realisation on Mum's face. She wasn't distressed; she looked reassured. At this stage Mum had accessed a memory by coming from a different angle.

We talked about Dad a bit more. Mum even revealed she'd sneakily scattered some of Dad's ashes at our T--- family home. I don't recall that story myself!

Mum thanked me for reminiscing and helping her remember. It was a gentle joyful moment.

(This week, together with my son, I visited Mum for a few days. Mum is in an aged facility, 1200km away from me and even further from him.)

“BASIC was a fine tool to learn programming with. But #programs in it occupied far too much of the limited working #memory of a #microcomputer, and it was horribly slow.

The way to get anything ambitious done was to write the program directly in the language #BASIC translated into: #assembly code, only one layer up from the #silicon.

Suddenly, you were responsible for the entire flow of very simple commands that allowed the computer to function.”

40 years ago, Elite was created and released by #IanBell and #DavidBraben.

Interesting. If on-board SRAM can be kept alive while rebooting the CPU, you can extract information stored in it.

"This paper presents Volt Boot, an attack that demonstrates a vulnerability of on-chip SRAM due to the physical separation common in modern system-on-chip power distribution networks."

📖 Vaidya et al. investigate how #hippocampal #CA1 #PlaceCells form expanding #memory representations over days. Using longitudinal in vivo recordings, they show that stable #PlaceFields progressively emerge as active cells increase their likelihood of remaining active across sessions. This gradual stabilization hinges on #behavioral‑timescale #SynapticPlasticity, offering a new model of how CA1 memories solidify w/o #CatastrophicOverwriting.

NatureFormation of an expanding memory representation in the hippocampus - Nature NeuroscienceMultiday imaging of CA1 neurons during learning reveals that the representation stabilizes as the number of readily retrievable, information-rich and stable place cells increases and suggests novel mechanisms of hippocampal memory formation.

Today I was able to recall and correctly use the word "subtend," which was precisely the word I needed and one I probably last heard from the mouth of my geometry teacher Mr. Morris in 1977.

It took a good 3 minutes of just sitting there, feeling the shape of the meaning in my belly, picturing it, and moving my lips ineffectually hoping they'd sense just a small recognizable piece of the word poking out of the dark ocean floor.

And then there it was.

Please celebrate with me. 🥳

#Herring used to feed in northern Norway and migrate south (>1000km) to spawn. A few years ago they abruptly stopped doing that.
The authors of a new study think older adults were overfished and didn't "teach" younger fish to migrate: nature.com/articles/s41586-025
