functional_dev··on A Faster Alternative to Jq
The backtracking implementation in jq is really the secret sauce for how it handles those complex filters without getting bogged down
functional_dev··on Starlink Mini as a failover
right, attenuation is particularly bad with Starlink because it operates in the Ku and Ka bands... wavelengths are small enough to be scattered by individual raindrops
functional_dev··on Intel Announces Arc Pro B70 and Arc Pro B65 GPUs
Yeah... attacks like LogoFAIL hit during the DXE and BDS phases when the firmware is acting as its own 'mini OS' before the handoff

Easier to comprehend here - https://vectree.io/c/uefi-firmware-architecture-principles

functional_dev··on Swift 6.3
yeah, Nim is great for that... much easier to explain to others than C or Zig especially for math code
functional_dev··on The EU still wants to scan your private messages and photos
I agree its unenforceable by design unless they control the OS
functional_dev··on HyperAgents: Self-referential self-improving agents
This 'self vs non-self' logic is very similar to how plants prevent self-pollination. They have a biological 'discrimination' system to recognize and reject their own genetic code.

Here is a breakdown - https://vectree.io/c/plant-self-incompatibility-logic

functional_dev··on On-Device AI Models Might Be the Next Reason to Upgrade Your iPhone
Here is a technical comparison to show how Knowledge Distillation works for on-device AI. It has visual maps for the Teacher vs Student models and explains things like 'Dark Knowledge' - https://vectree.io/compare/apple-intelligence-vs-knowledge-d...
functional_dev··on Olympic Committee bars transgender athletes from women’s events
It's very confusing topic. I rendered this visual map to show how SRY gene is the 'trigger' for development, not just having the Y chromosome. It helps see the signaling steps where things like AIS or XX syndrome happen: https://vectree.io/c/y-chromosome-genomic-signaling

To be honest, I'm a total introvert. I've spent my career as an IC, but I’m trying to transition into being an "Architect" of systems that people actually value and pay for.

The biggest hurdle for me isn't the code. It's talking to customers. I’ve always been told to read The Mom Test, but I’m a visual learner and usually too busy building to sit down with a business book.

I used Vectree to generate a schematic for the book’s core framework (the "juice") so I could understand the filter process at a glance. It turned out to be a perfect example of why I built this:

If you’re like me and want to understand a methodology or a complex system without the 200-page commitment, this is how I'm using the tool myself. I'd love to hear if this visual style helps you "get" it faster too.

You can download PDF of it as well!

functional_dev··on Ask HN: What Are You Working On? (March 2026)
Building a cheaper alternative to Twilio Voice Intelligence. Record phone calls, transcribe, generate AI summaries, enable semantic search over transcripts — $0.30/hour vs Twilio's $1.50/hour.

Stack is 15+ Go microservices on k3s. Cross-lingual semantic search is fun. Spanish query returns English calls with no translation code.

functional_dev··on I Hate Go, but It Saved My Startup: An Architectural Autopsy
It's probably SRI. I disabled "Email Address Obfuscation" in Cloudflare. It was probably misfiring.
functional_dev··on I Hate Go, but It Saved My Startup: An Architectural Autopsy
Thanks for follow up!

I suspect this is cloudflare doing some auto-minifying. It injects the "integrity" tags and something does not match. I will try to turn it off.

Thanks again!

That is strange. Just tried it on Firefox (Desktop), and it loaded fine. Any tips how to identify what is the issue?
functional_dev··on I Hate Go, but It Saved My Startup: An Architectural Autopsy
What browser are you using? It loads up for me fine. Could you help me to debug that, please?
functional_dev··on I Hate Go, but It Saved My Startup: An Architectural Autopsy
Could be both. I have used LLMs quite heavily on Rust (at work) and Haskell at leisure. And it is much harder to MOVE FAST.
functional_dev··on I Hate Go, but It Saved My Startup: An Architectural Autopsy
English is not my first language, and you nailed it. I used LLM to "polish" it. Probably too much. But I am open for questions if you like :)
functional_dev··on I Hate Go, but It Saved My Startup: An Architectural Autopsy
You are technically right, that is not a functional language. But it borrows many things from functional world :)
functional_dev··on I Hate Go, but It Saved My Startup: An Architectural Autopsy
Author here. I’m a huge FP snob (Rust/Scala) so using Go for this project kinda hurt at first.

But as a solo founder, I needed speed. The main thing I learned is that LLMs write amazing Go code. It's so simple and boilerplate-heavy that the AI almost never hallucinates.

Ended up building a distributed audio ingestion system that undercuts Twilio by like 80%.

Happy to answer questions about the architecture or other things.
