I have an M3 Ultra 96 GB, it works reasonably well with something like qwen/qwen3-vl-30b (fast) or openai/gpt-oss-120b (slow-ish) or openai/gpt-oss-20b (fast, largest context). I keep the latter loaded, and have a cronjob that generates a new MOTD for my shell every 15 minutes with information gathered from various sources.

What a misnomer! This doesn't help becoming sovereign, just vassals.

AWS European Vassal Cloud.

The moment USA decides to mandate no more software updates or security maintenance, it won't stand on its own for much longer.

Learn something else. Try Rust or Go.

E.g. Write a semi-naive datalog interpreter that uses sqlite as a backend (sql and datalog are computationally equivalent), make it available to Python and Typescript. (I am actually bored too, I might "steal" my own idea)

Have you tried Jax or Taichi? https://www.taichi-lang.org/

For Monte Carlo simulations, Pyro and tensorflow_probability have also nice abstractions.

New comment by rlupi in "Ask HN: Can systems function correctly without memory?"

rlupi — Sun, 28 Dec 2025 05:59:35 +0000

Rigidity in inputs lock down your system's evolution. The whole system need to evolve in lockstep if you need to change what the systems processes.

In practice, you either end up with an enlarging monolith or introducing state evolution (either explicitly, or by adding incremental input types that the system processes and expanding its API surface).

Beyond a certain inflection point of complexity, flexibility in introducing change becomes necessary.

> Not only would I like to see "skills" but also "processes" where you create a well defined order that tasks are accomplished in sequence. Repeatable templates. This would essentially include variables in the templates, set for replacement.

You can do this with Gemini commands and extensions.

You're asking for a database app. What prevents you from building one?

New comment by rlupi in "Ask HN: Is building a calm, non-gamified learning app a mistake?"

rlupi — Mon, 15 Dec 2025 16:52:48 +0000

I actively avoid anything that is gamified or uses engagement tricks.

I don't mind paying a subscription, if the app provides ongoing updates or new content that I value, or I understand why it has running costs. I would prefer if the app had extension packs, like games' DLCs over a subscription. If an app has a subscription, I will immediately cancel the subscription after subscribing to avoid the recurring cost (if I forget to cancel after year or so). If I find the app valuable, I will re-subscribe as needed.

New comment by rlupi in "Ask HN: How do you give a local AI model long-term memory?"

rlupi — Sat, 13 Dec 2025 11:32:28 +0000

I built an agent that has access to my diary, it has the ability to build hierarchical summaries of my diary, which help to compress context, I gave it tools to read pages, search using full text indexes and RAG (the former worked better, but I think it's largely because of limitation in my RAG implementation), it also has the ability to record memories (append to a specific markdown page). The latter are automatically included in the system prompt, when I invoke chat.

https://github.com/robertolupi/augmented-awareness/blob/main...

I use it mostly non-interactively, to summarize my past diary entries and to create a Message Of The Day (MOTD) shown when I launch a terminal.

rlupi — Tue, 02 Dec 2025 20:32:58 +0000

Do not forget that we're talking about supercomputers. Their interconnect makes machines not easily fungible, so even a low reduction in availability can have dramatic effects.

Also, after the end of the product life, replacement parts may no longer be available.

You need to get pretty creative with repair & refurbishment processes to counter these risks.

A CloudFlare tunnel?

https://developers.cloudflare.com/cloudflare-one/networks/co...

Although, you may also go with a 5$ virtual host (e.g. Linode Nanode 1 GB) and wireguard to build your own tunnel (or just the 5$ virtual host to run your server)

New comment by rlupi in "Ask HN: Did PageRank delay the invention of transformers and modern AI?"

rlupi — Sat, 22 Nov 2025 15:15:59 +0000

I doubt. Without the Google's money that PageRank created, others wouldn't have assembled the mix of compute, information, and brains that made the invention of transformers possible.

You need the vast amount of compute to accelerate matrix computation, that came from accelerating distbelief (https://research.google/pubs/large-scale-distributed-deep-ne...) for Search and Ads. Google developed custom ASICs (TPUs) because it would have been too costly to use CPUs and GPUs for their use cases.

You need the world information that came from Search.

You need the money to pay the researchers, and the willingness to do discretionary research that may not be directly applicable to your main products.

Transformers derive from neural machine translation.

rlupi — Tue, 09 Sep 2025 10:36:45 +0000

ASML is geopolitically relevant. If they want to offer dependable LLM-based solutions (even side products, like agents that help with their products) to their customers, they have to pick what partners to base their offering on.

Choosing something from US or China would add an external factor that could pull the rug at unexpected times. Mistral is safer for ASML because it has almost the same geopolitical constraints and stakeholders as they do.

Google search alerts are a thing (https://www.google.com/alerts). I'd expect a public figure, however niche their following is, would set them up to track the conversation about them.

rlupi — Mon, 18 Aug 2025 05:10:50 +0000

It would be nice to have the ability to define custom categories.

One option would be to let users drop custom folder in settings. These folders could have representative files in them (maybe with a custom Finder tag to identify them), then you can cluster documents by similarity like you are already doing.

Nice application! I am looking forward to see it evolve.

What are the chances of abandoning TPU-related projects where the company literally invested billions in infrastructure? Zero.
