Native apps, and a new security model adapted to the new paradigm. i don't think it will look like the web's security model I think the web becoming native is another possibility, and the one I'd prefer 🤞

I think jev could simulate an LLM by just using the tokens as its available choices In a sense, jev acts like an LLM but with a customizable tokenizer

I don't think that's settled yet, buckmaster claims that it is very unlikely an AI would choose that direction without their work they've been doing for the past year getting into the training data

Well, supposedly openAI is using "an internal model that is significantly more capable than GPT‑6 Astra. "

I've been trying to setup an agent to get news tailored for me, but it's been hard to get the feed of some sources, especially personal views on social media, and I've realized that these social platforms that are closed to agents will be at a disadvantage soon if they don't find an escape hatch

Life is full of things that, by complexity or design or lack of care or required time, are hard to navigate: healthcare, government, personal finance, school forms are all among them It is why I feel consumer AI is underrated. People muddle by, but are missing support & AI is good enough to help.

What would be the minimum # of likes to get a good quality here? BTW, I have been trying to think of what "good quality" here means, and I don't know how to think about it. Have u thought of some metric or maybe just a different framing that is more useful to think this fuzzy "quality"?

Marco D'Agostini @madacol.com · 22/08/2026
Yeah, I stopped using socials 6m ago and came back last month, that's why only 25 likes. But then does that mean it will be hard for someone who is infrequent to get enough likes in the 90 days window for the For You to have good quality?

Marco D'Agostini @madacol.com · 22/08/2026
I don't know if it is related, but my for you got much worse, I has much less relevant posts. I am not super frequent here on bluesky, but I still should have a good amount of likes in the last 90 day I did went on a rampage 2 or 3 days ago of applying "see less like this"

I am learning so much about architecture by vibe coding i didn't know terms like seam, or testing vertical slices. I did knew them intuitively but I was struggling to communicate that to LLMs Also a shoutout to @mattpocock.com 's YT channel for helping me solidify these and other concepts

This is codex, I just asked him to find the root cause of a health issue by only asking yes/no questions. And now I don't know how to continue 🤦‍♂️
A WhatsApp conversation with an LLM agent, showing the agent become incoherent:

...

🤖 Do you have diabetes, or do you take a GLP-1 medicine such as Ozempic, Wegovy, Mounjaro, or similar?

no

(Oh btw, leaving the tab open also preserves editions you have made on inputs, scrolling position, and other states of the page), so you can rebuild what you were thinking when you opened that tab weeks/months/years ago.

Marco D'Agostini @madacol.com · 22/03/2026
The problem with those solutions is that they tend to be even higher friction than just deciding if to close or not the tab, because for them to be useful you have to classify them in some way, and I kid you not, leaving tabs open leaves you with a surrounding context that bookmarks do not preserve

Marco D'Agostini @madacol.com · 22/03/2026
I've had 1000+, and I have some idea where some of them are, but the vast majority (~900) are just leftovers of an area of tabs lost in the vastness of UI wasted space, pure cognitive chaos that I can tap into for an inspiration that was once felt but lost to the oblivion of lack of time

Marco D'Agostini @madacol.com · 22/03/2026
From my perspective, leaving the tab open is just the laziest strategy to manage tabs, I don't have to decide if I am finished with the tab right now, and I also get some kind of chronological sorted history of tabs opened so ... why not?

I am still wrapping my head around the fact that I am developing software inside a mainstream chat app
This image is a screenshot of a WhatsApp conversation, depicting a technical workflow for updating a bot's test suite.

The chat includes the following key elements:

* **Bot Message:** A message with a robot emoji explains that a 1-line JavaScript code block needs to be updated because a new rule requires a minimum of 5 lines for it to render as an image.
* **File Edit:** An "Edit" notification displays the file path: `/home/mada/whatsapp-llm-bot/tests/sendBlocks.test.js`.
* **Code Diff:** A visual diff shows a single line, `console.log("hello");`, being replaced by a multi-line `greet` function and a function call within a `markdown` constant.
* **Bash Command:** A final message shows a command block for running tests using `pnpm test`, with a 60-second timeout.

When @t3.gg published his t3code project video, I wasn't aware that the agent SDK could be used in that way, the next day I prompted Cc to make my WhatsApp agent custom harness modular and implement the Claude agent SDK, and it worked (after some back and forth that is still going after 24h 😅)

In memory of all the walls AI was about to hit.
Image by Nano Banana Pro.

A cinematic, wide-angle shot of a sunlit, overgrown cemetery filled with rows of weathered gray tombstones. Every headstone is engraved with the name "AI WALL" in a classic serif font. Below the names, various short date ranges from the past few years are listed, such as "JAN 2024 - FEB 2024" and "FEB 2026 - MAR 2026." Some stones include epitaphs like "Here lies a bad prediction," "Didn't age well," and "Spoke too soon." The scene is a satirical take on frequent but failed predictions that AI development would stop progressing.

Everyone wants to blame the content: misinformation, bots, polarisation. That mistakes catalysts and symptoms for the underlying causes. The crisis isn’t bad information, it's that the very information infrastructure we relied on to create a shared understand of the world had changed completely.

if only it were ""politically correct"" to do so years ago, we would've had a much better outcome under the democratic party than what we are currently getting. But we have learned the hard way that this is a golden opportunity for us, no one even dreamed it was possible to become a US colony

Large language models are often used to answer queries grounded in large text corpora (e.g. codebases, legal documents, or chat histories) by placing the entire corpus in the context window and leveraging in-context learning (ICL). Although current models support contexts of 100K-1M tokens, this setup is costly to serve because the memory consumption of the KV cache scales with input length. We explore an alternative: training a smaller KV cache offline on each corpus. At inference time, we load this trained KV cache, which we call a Cartridge, and decode a response. Critically, the cost of training a Cartridge can be amortized across all the queries referencing the same corpus. However, we find that the naive approach of training the Cartridge with next-token prediction on the corpus is not competitive with ICL. Instead, we propose self-study, a training recipe in which we generate synthetic conversations about the corpus and train the Cartridge with a context-distillation objective. We find that Cartridges trained with self-study replicate the functionality of ICL, while being significantly cheaper to serve. On challenging long-context benchmarks, Cartridges trained with self-study match ICL performance while using 38.6x less memory and enabling 26.4x higher throughput. Self-study also extends the model's effective context length (e.g. from 128k to 484k tokens on MTOB) and surprisingly, leads to Cartridges that can be composed at inference time without retraining.
