Increíble de ver a los “expertos” en solventar la emergencia de vivienda que vive España! En cada televisión! @telediario_tve @A3Noticias @tele5_noticias @noticias_cuatro La realidad es que tenemos a políticos que intentan crear decretos y soluciones cuando no tienen la preparación ni el conocimiento para idear una solución real al problema que vivimos.
España no tiene un problema de falta de decretos. Tiene un problema de falta de viviendas.
Y mientras el Gobierno siga confundiendo anunciar medidas con resolver problemas, seguiremos pagando las consecuencias de su inacción.
Subvencionar la demanda sin aumentar la oferta presiona los precios. Regular cada vez más un mercado sin construir vivienda nueva no elimina la escasez: la administra. Castigar fiscalmente una modalidad de alquiler puede cambiar incentivos, pero tampoco pone un solo ladrillo.
El Gobierno puede aprobar todas las medidas que quiera y venderlas como grandes soluciones. Puede encadenar decretos, anuncios y campañas de propaganda. Pero hay una pregunta que desmonta cualquier discurso:
¿Cuántas viviendas nuevas crea todo esto?
Porque la vivienda no se abarata repartiendo la escasez. Se abarata acabando con ella.
España necesita construir. Mucho.
Más suelo disponible. Licencias en meses, no en años. Más densidad donde sea posible. Seguridad jurídica. Muchísima más vivienda pública y también privada.
Pero el Gobierno no está haciendo lo necesario. Prefiere intervenir sobre las pocas viviendas que existen antes que crear las condiciones para que haya muchas más. Prefiere presentar parches como soluciones y cargar sobre propietarios, promotores y ciudadanos el coste de su fracaso.
Lo demás puede servir para redistribuir, proteger a determinados colectivos o cambiar incentivos. Pero no confundamos eso con solucionar el problema de fondo.
No se arregla una falta de vivienda repartiendo mejor las pocas casas que existen. Se arregla haciendo que existan muchas más.
Menos propaganda. Menos parches. Menos obsesión por intervenir sobre el mismo piso.
Más oferta. Más construcción. Más casas.

The skill atrophy from not coding can get pretty serious, but at least many of us spent years in the industry before AI. So even if the syntax gets rusty, the principles and the logical and analytical thinking we built up will still be there.
The real issue will be future devs and software engineers entering the field without ever having written a single line of code… they’re cooked.

Before Cursor. Before VS Code. Before everything got flooded with AI and vibe coding.
There was another era. An era every veteran developer remembers with a mix of nostalgia… and pain.
Back then, we’d spend hours fighting our IDEs just to get a simple “Hello World” running.
Here’s a throwback to 6 IDEs/editors that shaped us long before the AI era 👇🧵

This weekend I made some progress on my spooky theme park builder game for the #vibejam 👻🎢
🎢 New rides
🗿 More decorations: statues, lamps, bins, plants…
🧠 Improved guest behavior: show emotions, hunger, thirst, and smarter decisions based on fun/price ratio
💾 Save / Load system
🌧️ Rain and thunder
🧩 Challenges now have 3 difficulty tiers
This has been a super fun experience so far 😄
Would love to hear your feedback! 👇

LLM Knowledge Bases
Something I'm finding very useful recently: using LLMs to build personal knowledge bases for various topics of research interest. In this way, a large fraction of my recent token throughput is going less into manipulating code, and more into manipulating knowledge (stored as markdown and images). The latest LLMs are quite good at it. So:
Data ingest:
I index source documents (articles, papers, repos, datasets, images, etc.) into a raw/ directory, then I use an LLM to incrementally "compile" a wiki, which is just a collection of .md files in a directory structure. The wiki includes summaries of all the data in raw/, backlinks, and then it categorizes data into concepts, writes articles for them, and links them all. To convert web articles into .md files I like to use the Obsidian Web Clipper extension, and then I also use a hotkey to download all the related images to local so that my LLM can easily reference them.
IDE:
I use Obsidian as the IDE "frontend" where I can view the raw data, the the compiled wiki, and the derived visualizations. Important to note that the LLM writes and maintains all of the data of the wiki, I rarely touch it directly. I've played with a few Obsidian plugins to render and view data in other ways (e.g. Marp for slides).
Q&A:
Where things get interesting is that once your wiki is big enough (e.g. mine on some recent research is ~100 articles and ~400K words), you can ask your LLM agent all kinds of complex questions against the wiki, and it will go off, research the answers, etc. I thought I had to reach for fancy RAG, but the LLM has been pretty good about auto-maintaining index files and brief summaries of all the documents and it reads all the important related data fairly easily at this ~small scale.
Output:
Instead of getting answers in text/terminal, I like to have it render markdown files for me, or slide shows (Marp format), or matplotlib images, all of which I then view again in Obsidian. You can imagine many other visual output formats depending on the query. Often, I end up "filing" the outputs back into the wiki to enhance it for further queries. So my own explorations and queries always "add up" in the knowledge base.
Linting:
I've run some LLM "health checks" over the wiki to e.g. find inconsistent data, impute missing data (with web searchers), find interesting connections for new article candidates, etc., to incrementally clean up the wiki and enhance its overall data integrity. The LLMs are quite good at suggesting further questions to ask and look into.
Extra tools:
I find myself developing additional tools to process the data, e.g. I vibe coded a small and naive search engine over the wiki, which I both use directly (in a web ui), but more often I want to hand it off to an LLM via CLI as a tool for larger queries.
Further explorations:
As the repo grows, the natural desire is to also think about synthetic data generation + finetuning to have your LLM "know" the data in its weights instead of just context windows.
TLDR: raw data from a given number of sources is collected, then compiled by an LLM into a .md wiki, then operated on by various CLIs by the LLM to do Q&A and to incrementally enhance the wiki, and all of it viewable in Obsidian. You rarely ever write or edit the wiki manually, it's the domain of the LLM. I think there is room here for an incredible new product instead of a hacky collection of scripts.
