I just wanted to comment on the brilliance of the post title.

Plugin security is one thing. Plugin budget is another thing... much larger of a problem in some cases.

I'm not sure if this an urban legend but, it's cool anyway. The name "Ramones" is an adaptation from "Jamon", Paul Jamon, a fake name Paul Mccartney used in hotel check-ins to avoid stalking fans. So most if not all Ramones members through history changed their last name, family name, to "Ramone" to honor the tradition and be a Remone forever in Rock history. Again, this is cool enough for me on top of the great music they've made.

"GitHub Open Source Contributions" aside, everything else falls into the consumption/intake/internal categories; thin data on production/output/external ones.

Tell me about it... that infinite Ctrl + Shift + L sequence circling through all credentials from all subdomains. Then you brain betrays you making you skip the right credential... ugh, now you'll circle the entire set again. Annoying.

My family members know of my physical "red notebook" and its location. It has instructions on how to access my digital life on detail.

Sounds more like a lobby thing. Once a government finds a new "recipe" to be worked out with global vendors, meaning, a new way to allocate budget with a strong social justification (e.g. protect children, fight terrorism etc.), governments from other nations jump into the matter and literally copy/paste it locally. In short, whoever comes up with a creative idea to allocate public budget will serve as the basis for others to copy.

New comment by rodolphoarruda in "I canceled my book deal"

rodolphoarruda — Wed, 31 Dec 2025 21:10:05 +0000

I'm writing my first book now. It's a novel aimed at teenagers and young adults, in a technical format similar to "The Phoenix Project" by Gene Kim et al., if you're familiar with it. It explores FOSS, non-proprietary file formats, digital preservation, cryptography, and the concept of freedom as a whole. I resonate with the author of the article who discusses motivation to write and the "existential crisis" that comes and goes almost every day. I've been fighting those negative feelings by adopting the mindset that I'm writing the book for myself. It's a book I've always wanted to read, which I can then lend to my teenage children so they can read it as well. Everything else (commercially speaking) will be a nice consequence of this endeavor.

Amazing: the website's index page has the book's index in it. While this makes perfect sense, it's a kind of a feature that is becoming rare in today's tech book websites which display all sorts of marketing fluff, social confirmations etc and not the structure of the book itself.

I first read about Unpoly in Stephan Schmidt's Radical Simplicity website[1], I liked it's value prop and decided to try it. I found it bit too complex just as you said. A long time later I came across htmx and decided to try it even after reading a side comment that the library was "like unpoly". 15 minutes later I had a simple to-do list running htmx ajax calls using php and mysqlite in the backend. It was so easy I could not believe such thing could exist. Then I decided to read the Hypermedia book and never stopped using htmx in my projects.

Using metaphors is dangerous, but I would dare to say that big tech AI is like cement suppliers. It's too low level of a service. In civil engineering you have the option to contract value added suppliers that will give you prefabricated pieces in concrete or steel you could be using to build your construction.

I'm seeing a lot of AI firms building value added services on top of big tech "foundational" AI offerings. Value addition can start very early at a clear plans/billing structure, going through rate limiting, documentation and extra features that will bring stability or consistency to our AI enhanced products.

Going the other way around (I tried) and building things on top of big tech AI is challenging starting at the fundamentals as the OP described well.

I've been catching myself thinking about this idea for the last two years. Maybe it's my old obsession with PKI and "personal digital infrastructures" that were both promised to us in the early days of the commercial Internet, but never turned concrete for various reasons.

IMHO, the best we could have today in terms of digital infrastructure is a personal/family level custom Mastodon node with basic Internet services like email, posts, tasks, chat, IM etc. but implemented in a way that all data would be portable to other services (open standards) and its storage would be "bottomless", meaning that users wouldn't have to worry about storage limitation for photos/videos for instance, as they would be sharing resources with other nodes worldwide. There would have to be some monetary incentive(s), of course, but they would be secondary to the bigger cause of keeping a true cyber interconnected community outside big tech.

> you’re copying entire works from unauthorized distributors

Yep, this sounds like an issue. So the idea from MP3 early days of "let me download these files as a backup before I lend my CD collection to my cousin" is not a real option.

A question to the community: would it be a (legal) problem if I decided to download digital copies of the physical books I already have in my bookshelf? I was thinking on using Anna's Archive for that. Hobby project.

I like this website. It's very entertaining to me, and a bit nostalgic too. And those minimalist websites also help us remember the importance of building things to last the effects of time. Most of them are good candidates to stay online for the next 15 or 20 Internet years to come (almost like eternity in human terms).
