Ask HN: What are you working on? (August 2026)
Today you you can self-host some models, yet this does not mean you can safely browse the web with it, and automate tasks that would interact with your email account, your bank account and your clients.
This is the reason why I left Mozilla, to work full-time on fixing these problems.
Prompt-injection, hallucinations and private information leakage might not be fixable, but they can be identified 100% of the time, deterministically, before any undesirable consequences.
However, asking people to pay first without an established brand nor the ability to audit the code requires a lot of trust. Without any additional judgement about the product, I would never recommend anybody to do that by fear of spyware, phishing or worse …
From the same consideration, I intend to open source my solutions. At the very least offer auditing capabilities to people like me, who are too paranoiac about security and privacy.
On the topic, I do not want to ask the user to always vouch for every usage. My goal is to detect ahead of executing any command, and offer options to re-try automatically, strip the leaking context, abstract the information or accept it. Only asking the user when there is a doubt, while not bothering the user when there is no issue.
Meanwhile, I decided to revive my Rust liblinux project. Rust has come a long way since 2019, notably the inline assembly macro has been stabilized. I will learn Rust this time!
So I'm building an app a week and focusing on solving niche problems I've experienced in my own life to start
I think it's never been easier to build prototypes, but because of all of the slop, building community and finding users around them are harder than ever before
This latter part I think is going to be the hardest part of going out on my own
But going to try
Things I'm working on right now:
https://a2ciple.pt/ - testing prep for a language exam required for residency & citizenship in Portugal
https://basehub.org/ - a docs site for agents to get the latest context on Base, an Ethereum L2
https://playgokab.com/ - a vocab game to learn words in diff languages
https://mru.space/ - a protocol to run software that gracefully degrades across failing hardware
https://shiponeshot.com/ - a framework to help me ship prototypes more quickly
Anyhow, cheers :)
We have built a few apps recently and what we observe is that while building the app has gotten dramatically faster with AI, everything around it still takes a surprising amount of human effort - testing, debugging, reviewing, store submissions, releases, monitoring, and keeping things running.
Deckhand is our attempt to make that entire loop faster, while keeping humans in control. Would love to hear how others are shipping and operating mobile apps.
Basically I'm finding myself in a bind where:
- I spend too much time doomscrolling (X, reddit, HN etc) - AI is making me lose touch with a lot of basic skills like coding, and I was already losing touch with doing real math
So I built an extension that blocks sites and forces you to actually solve a problem before you can get to a distracting site. The idea is to 1) block the reflex of visiting a site and getting a dopamine hit, and 2) at least get some mild cognitive benefit from it. I use it myself.
Even experimented with per-client Linux users. Per-client calendars & routines. Per client knowledge-base, etc
Very curious to see what you come up with.
People seem to love the concept so far and are starting to sign up, now just need to figure out how to get them to actually use it

I always get frustrated when using local file transfer tools like:
Dukto: was my personal favorite, but is tiring to run cross platform, and most importantly does not support transfer resumes (so if copy got cancelled/disconnected at 99% you either have to copy again or search for the diff and copy it manually)
LocalSend: pretty good cross platform support, but does not work when connecting 2 devices using a LAN cable, and resume support is poorish
So I'm building Tensou to be an alternative that doesn't compromise all these features. Supporting resumes, folder syncing similar to rsync, cross platform (well I don't have a Mac to test on but it should work, and mobile support is planned)
Performance wise it's on par with Dukto and even slightly better with large files (and I'm still working on optimizations for small files too)
Would like to hear HN's feedback or what other features should I add? My goal with Tensou is to be the best, most performant and feature rich local file transfer tool ever.
