Re the spikejapan blog: The author’s About page includes this line which describes my experience of the article very accurately, having bailed after a couple of minutes:

“It's a species of anti-blog, as there is no way that you'll get through a post if you suffer from any kind of attention-deficit disorder; even then, you may need a strong cup of coffee and an hour to kill.”

The github repo link from the npm page doesn't work, so I guess the author had second thoughts.

I was just fighting ffmpeg earlier today, or rather Gemini and Claude were fighting it. Task: create a video that is a pan across a photo, followed by a scale/zoom.

Probably easy for some people, but I had no clue and the LLMs weren't doing that well either. Things took a turn for the better when I asked Gemini for an alternative tool.

The answer was Vapoursynth - https://www.vapoursynth.com/doc/introduction.html#introducti...

Again, the LLM did the work, but it was able to do so. Since Vapoursynth is driven by python scripts (though with the extension .vpy), it was easy for me to make adjustments.

These were great and I am always on the lookout for something similar, but no luck so far.

I also liked that there was a neckband - easy to take the buds out when not needed and leave them hanging, and of course more power in a larger battery.

Indeed! Quite interesting.

title: The neural basis for uncertainty processing in hierarchical decision making

abstract: Hierarchical decisions in natural environments require processing uncertainty across multiple levels, but existing models struggle to explain how animals perform flexible, goal-directed behaviors under such conditions. Here we introduce CogLinks, biologically grounded neural architectures that combine corticostriatal circuits for reinforcement learning and frontal thalamocortical networks for executive control. Through mathematical analysis and targeted lesion, we show that these systems specialize in different forms of uncertainty, and their interaction supports hierarchical decisions by regulating efficient exploration, and strategy switching. We apply CogLinks to a computational psychiatry problem, linking neural dysfunction in schizophrenia to atypical reasoning patterns in decision making. Overall, CogLink fills an important gap in the computational landscape, providing a bridge from neural substrates to higher cognition.

N8n raises $180M 10 months ago

Just participated in a hackathon where my team used n8n. We found it didn't have good connectors for getting data from Kinesis streams or Slack. Given the abbreviated timeline of the hackathon we ended up simulating the Kinesis input and dropping the interactive Slack part of our project, which was unfortunate.

I hope they spend a good bit of the $180M on building out their input connectors.

gotta source or two? it's an ungooglable topic due to "see pigeon do funny dance" social media spam

Speculation by a non-accountant:

At the end Nvidia retains ownership of what are probably very low value assets.

Contrast that with car leases: there is a robust market for used cars.

Nvidia is in effect financing the GPUs by not requiring the full payment up front.

Do the lease payments add up to the total cost?

Expresses a longing for the semantic web.

Remember Semantic Web? The web was supposed to evolve into semantically structured, linked, machine-readable data that would enable amazing opportunities. That never happened.

I think the lesson to be learned is in answering the question "Why didn't the semantic web happen?"
