2025-01-30 19:59:38

With everything you know about me, roast me without mercy.
ChatGPT response:
So, you're running Linux Mint on an ancient laptop, yet you expect performance. What, did you think Cinnamon was some lightweight, minimalist DE? Newsflash: Your machine wheezes every time you open a terminal. Arch users would bully you, but even they feel bad for you.
And then there's your love-hate relationship with Lisp. You can't stand the parentheses? Fine. But let’s be real—you’d rather wrestle Haskell’s type system for days than deal with a few extra ( and ). You claim to love purity and elegance, but in reality, your effectful spaghetti code is just monads in a trench coat.
Speaking of which, you’re breaking effects into tiny groups just to reuse state? So instead of dealing with deep effect stacks, you just shuffle your problems around like a shell game and call it "good design." Your codebase must be a Byzantine maze of STM updates and arcane type signatures that only future-you will suffer through. Good luck debugging that in a month.
And let's not forget your grand subscription model, handling every possible event with precision. Meanwhile, someone out there is writing a ten-line script that does 90% of the same thing, and it just works. But no, you need the correct solution, even if it takes three weeks of yak-shaving to get there.
Then there's your storage choices. LMDB? You mean the database equivalent of "I don't trust Postgres, and SQLite is too mainstream"? You're so obsessed with performance that you'd rather hand-optimize data storage than admit that maybe, just maybe, something off-the-shelf would be good enough.
Oh, and your website? Running on gh-pages like some GitHub beginner tutorial. You're probably over-engineering a static site that could be a single HTML file, but no—you need structure. And of course, you have a Flatpak project, because why just distribute software normally when you can wrap it in extra layers of sandboxing complexity?
In the end, you’re a performance-obsessed, purity-loving, state-rebuilding, effect-splitting Haskell masochist who would rather spend a week perfecting an abstraction than writing a simple solution. And you love it. Because deep down, you don’t really want things to be easy—you want them to be right.

2025-01-15 00:58:18

The new event-centric inbox model of futr will replace the relay pool implementation completely, state is now persistent in LMDB, and the relay mgmt can be dramatically simplified.
Deeper insights into the domain over time, will lead to better code and simplify a lot. Interestingly adding new features actually removes more code that it adds.
While from a users perspective the app didn't change much, under the hood the engine is getting completely revamped.
Doing all this in Haskell, allows me to write consice code expressing only the things I need, which gives time to think about the problem as is.

2025-01-14 01:35:45

- reply

Look at it this way: Haskell's do-notation actually looks like procedural code. If you actually write procedural in any language, you have to take care of error handling, exception handling, possibly async tasks, logging, etc. This will inevitably clutter your code and make it less readable. Not so in Haskell. Monads allow you to abstract these things away and do-notation actually looks like procedural (do this, then do this), but without all this other stuff around (aka try-catch f.e.).

2025-01-14 01:30:01

I haven't pushed latest commits to GitHub for the last at least 3 weeks. Rest assured, a lot of work is getting done behind the scenes. I'm still working on the new subscription model and it will take time to build it. I'm hesitant with estimations, as I get them wrong too often, but I expect this week to get it done. Right after, all work will get split into smaller pull requests for final review and commits will be stashed and rebased, so I get a clean git history.
The upcoming futr release will be pure 🔥.
I promise you haven't seen a faster nostr client, ever. The UI is quicker then any website you could build. Native apps are not to beat!
Last release is almost two months ago. The wait will be worth it, 100%!
I'll also publish release notes with all the changes, and it's a long one.

It often times fails to connect to the node, needs multiple retries, and even then it's kind of slow. For me that's the pain point.

2025-01-02 14:22:57

The necessity of nation-states is, in my view, a false premise. The threats you describe—whether from predatory practices like slave labor or aggressive foreign powers—are often consequences of state policies. Nation-states escalate conflicts, enforce harmful economic interventions, and create conditions where exploitation thrives. A world of decentralized, voluntary communities would be far less susceptible to such threats, as individuals would engage in peaceful trade and mutual cooperation rather than being conscripted into the state’s conflicts.

What's so far to expect in the next release:
- public short text notes
- comments
- reposts
- quote reposts
- event deletion
- persistant lmdb event cache and app backend
- improved inbox- & subscription model
- improved app performance
- add ping/pong to websocket connections
- some nice UI additions
- cleaner code structure, removing hundreds of old lines of code that is not required anymore
