Maybe off-topic but,

If you're not familiar with the CMU DB Group you might want to check out their eccentric teaching style [1].

I absolutely love their gangsta intros like [2] and pre-lecture dj sets like [3].

I also remember a video where he was lecturing with someone sleeping on the floor in the background for some reason. I can't find that video right now.

Not too sure about the context or Andy's biography, I'll research that later, I'm even more curious now.

> I decided to leave my phone at home

I used to do this too but soon I realized I wanted my phone for payments (say, coffee) and/or unlocking public bikes (like Lime).

Now I have 2 phones: - Phone A with my SIM, internet, payment cards, but unlogged from any internet account - Phone B, no SIM, usually connected to Phone A via hotspot, with email, messaging apps, logged into hacker news and everything.

When I want to take an offline walk/ebike-ride I only bring Phone A with me.

I see more and more blog posts that contain interactive elements. Despite the general enshittification of the average blog and the internet, this feels like a 'modern' touch that actually adds something valuable to the sufficient ad-free no-popups old blog style.

danielfalbo··on Reflections on AI at the End of 2025
Exactly. The singularity is already here. It's just "programmers + AI" as a whole, rather than independent self-improvements of the AI.

I wonder how a "programmers + AI" self-improving loop is different from an "AI only" one.

I'm not sure antirez is involved in any business decision making process at Redis Ltd.

He may not be part of "they".

I think he's referring to AI safety.

danielfalbo··on Reflections on AI at the End of 2025
> There are certain tasks, like improving a given program for speed, for instance, where in theory the model can continue to make progress with a very clear reward signal for a very long time.

This makes me think: I wonder if Goodhart's law[1] may apply here. I wonder if, for instance, optimizing for speed may produce code that is faster but harder to understand and extend. Should we care or would it be ok for AI to produce code that passes all tests and is faster? Would the AI become good at creating explanations for humans as a side effect?

And if Goodhard's law doesn't apply, why is it? Is it because we're only doing RLVR fine-tuning on the last layers of the network so all the generality of the pre-training is not lost? And if this is the case, could this be a limitation in not being able to be creative enough to come up with move 37?

danielfalbo··on Ask HN: What Are You Working On? (December 2025)
Building my own static site generator using vanilla Python and SQLite for my personal blog and Notion-like second-brain https://github.com/danielfalbo/prev
danielfalbo··on Show HN: prev.js: Blog/PKM SSG using SQLite and Python. Compiles in 5s on Vercel
Author here. I previously used Next.js for my blog and Notion for my collection of linked books/resources/notes, but I wasn't happy with the compilation time of Next.js for a simple blog and the slowness of Notion. So I built my own solution for both from scratch.

I use Python for the logic (zero dependencies) and SQLite for the data.

I still have to migrate the data, but the core is already online at https://danielfalbo.com

For instance, I have an SQLite table for resources and one for authors, linked together.

The indices for each are automatically generated at https://danielfalbo.com/resources and https://danielfalbo.com/authors

If you open, for example, an author's page, you'll find hyperlinks to all their resources in the first part of the document, and vice versa for the resources. Example: https://danielfalbo.com/resources/fabric-of-reality

The blog will live in the "notes" table, which behaves similarly at https://danielfalbo.com/notes (actually, I'm still thinking whether to split the notes and the blog tables or keep them together, but infrastructure-wise it doesn't change anything).

A fun feature is the dynamic calculation of my age at the moment of writing of any blog post, for example, seen at https://danielfalbo.com/notes/essentials

There is also a lightweight livee preview feature for nice offline html content editing.

I still have to finish migrating everything and might realize there are gaps along the way, but the goal is relevant-features parity with https://old.danielfalbo.com/weblog and https://danielfalbo.notion.site/3cce7ff647e94470ba1342211337...
