| Main focus is https://wheretodrink.beer, collecting and
| cataloging craft beer venues from around the world. No ambition
| of being exhaustive, but aiming for a curated and substantial
| list. After the last thread, a bunch of people added their
| suggestions, thanks! It helped add interesting new venues from
| cities I hadn't covered yet.
|
| I'm very slowly layering on features, and have a few spin-off
| ideas I'll keep brewing on for later. The hardest problem thus
| far has been attempting to automate popularity rankings and
| automatic removal of defunct venues without breaching a bunch of
| ToS.
|
| Also made https://drnk.beer, a small side project offering beer-
| related linkpages and @handles for Bluesky (AT Protocol). It's
| been on the backburner, but still very much live.
|
| Probably looking for another small project for the next few
| months to focus on something else for a while. Always curious to
| see what others are building and doing. Thanks for sharing!

|
| Started with the cities I know well, and after that adding on
| countries or cities close by, main focus has been Europe. At
| one point I tried to use ratebeer's dataset as a starting
| point, before they closed down, but it was so horribly
| outdated and irrelevant that it was more work than sourcing
| manually.
|
| So I basically look for existing blog-ish top-lists for a
| city, then try to verify the information with search, social
| media, untappd, etc. Looking for social proof that the venue
| is operational and relevant.
|
| To keep it updated I have some very rudimentary monthly tasks
| to ping a venue's website and notify me on things that signal
| they're closed. I also email myself a list of 10 random
| venues with all relevant links daily, so I can do a manual 5
| min alive check.

|
| * OSINT (r00m101 just beat me to it by launching...)
|
| * Research into recommendation algorithms, advertising placement

|
| * Marketing (ad libraries, detailed analysis of content given

|
| * Market research for products
|
| * Sales teams can use it to find exact mentions of other

| Just prototyping at the moment, but the goal is to allow users to

| forms, but encrypted and one time only (read once).
|
| The use case I have in mind is allowing businesses to create GDPR

| specific customers, and once the data is received by the business
| delete it from the server.
|
| This could be useful to businesses that don't have a customer-
| facing portal, but have to deal with PII and the customer needs
| to consent and verify the data and what it's used for.
|
| The data is encrypted client side (web crypto) and the password
| either shared in the url (in the hash fragment, also encrypted by
| a key stored on the server) or by other means (eg. could be the
| recipient's dob or id number or some other previously shared or
| known value).
|
| Still trying to figure out the details, use cases, business value
| but the core backend is done so is the client-side crypto stuff.
| I managed to get chunked AES-GCM working so that it doesn't load
| the whole file in memory in order to encrypt it, it does that in
| chunks of let's say 2MB. Chrome also has chunked requests (in

| Since I had so much trouble managing my entire digital
| information universe [1], I decided to scratch my itch and solve
| it for myself and maybe others as well. Here are my ideas about
| my product:
|
| - Manages the entire range of personal (and maybe business)
| information/content: Documents, Media, Messages (email, instant,
| etc.), Contacts, Bookmarks, Calendar, etc.
|
| - Tag based, so that the question of where to put and find
| content is quite a bit easier to answer. Think of a set of flat
| folders, on one or more devices, within which the files are
| stored with tags attached. However, there will be some
| improvements on the usual implementation of tag-based systems out
| in the wild. Since people find navigating/browsing files more
| natural than searching, virtual folders will be dynamically
| generated to provide guided navigation. Also, entire folders can
| also be treated as atomic and tagged/managed as one object,
| useful for repositories and projects. And, heuristics (and maybe
| AI) will be used to automatically tag files when they are
| imported into the tool, greatly reducing the tedium of adding
| tags the first time.
|
| - Is file based, so that all information is ultimately physically
| stored as individual files. This allows information to be more
| easily managed on a physical level: moved around, backed up,
| exported/imported, searched, navigated, etc. without the
| restrictions imposed by the opaque islands of information we have
| now. So in addition to docs, each email/instant message, contact,
| scheduled task/event, bookmark, etc. would ultimately be stored
| as a file, unlocking all the things you can do with files.
|
| - Has a local web-based UI launched from a local agent, so actual
| file content does not usually need to move across the network and
| stays local, and the tool is also easily multi-platform, with
| consistent UI irrespective of platform.
|
| - Provides a cloud web UI as well, that communicates with content
| devices through the local agent, so that content stored across
| multiple devices can be managed in one central location, even
| without direct access to those devices, team/org features can be
| provided. However, file content still stays local, except when
| shared.
|
| - Provides tools for exporting data as file from the data islands
| of various apps and service, and backing up as files to cloud
| storage services.
|
| My vision is a situation where I am in charge of my own data
| irrespective of whatever device, app, or service I use, can
| ensure that it is always available and will not be lost, and that
| I can easily navigate and search through it all to find whatever
| I want, no matter how scattered and massive it is.
|
| I welcome your thoughts. What would make this work for you? Would
| you mostly prefer a cloud UI or a local UI? Are there any
| technical or market gotchas I should be aware of?
|
| [1] Here are some of my issues with personal information
| management affordances of current tech, which is driving me to
| work on a solution:
|
| - Our data is too bound to device and vendor islands. Can't
| easily move my information across Apple/Google/Whatsapp, etc
| accounts. Can't easily merge and de-duplicate either. I almost
| always somehow lose data whenever I have to move to a new phone,
| etc.
|
| - Hard to own your data on many services: Discord, Slack, etc.
| Can't easily export, search
|
| - Hard to have a 360 overview and handle on all your data assets
| and query them in consistent manner
|
| - Files as a unit of information storage and management is very
| ergonomic; we shouldn't allow that concept to be buried by
| vendors for their own gain.

| your UI/web design later, it's easy to know which pairs have
| accessible color contrast.
|
| For example, you can design your palette so that green-600,
| red-600, blue-600, all contrast against grey-50, and the same for
| any other 600 grade vs 50 grade color, like green-600 vs
| green-50.
|
| That way you won't run into failing color contrast surprises

| heading text and body text), a red danger alert box, a green
| success alert box etc. against different color backgrounds.

|

|
| A Datomic-like database on top of OPFS - where queries become

| trigrams, per-finger performance, etc. - SmartPractice mode using
| LLMs to create personalized exercises - Topic-based practice
| (coding, literature, etc.)
|
| I started this out of passion for typing. I went from 40wpm to
| ~120wpm (wrote about it here if you're interested:
| https://www.typequicker.com/blog/learn-touch-typing) and it

| Currently, we're doing a lot of analysis work on character

| features.

|
| 1. Typing uppercase characters counts as a mistake

|
| 2. WPM is not a useful metric on its own
|
| WPM can rise and fall depending on the length of the word. The

|
| Speaking of which, there are some more statistic things that
| could help, like measuring how fast you are at fixing the

| two-letter combinations, because the context of the third
| letter might help, but you do need more data to gain a

|
| It started as an experiment in writing LINQ-style queries over

| - declarative queries built into the language
|
| - a register-based VM designed for analysis and optimization
|
| - an intermediate representation with liveness analysis, constant

|
| - static type inference, inline tests, and golden snapshot
| support
|
| Example: type Person { name: string

| Person let adults = from p in people
| where p.age >= 18 select { name: p.name, age:
| p.age } for a in adults { print(a.name, "is",
| a.age) } save adults to "adults.json"
|
| The long-term goal is to make a small, expressive language for

| "sweets"... This allowed waiters to retrieve items and deliver
| them to customers.
|
| The system was used by around 40 users, with new waiters joining

| the app functioned without internet or Wi-Fi, gracefully
| downgraded (If a waiter didn't use the app due by choice or due
| to technical problems, they could manually relay orders to
| cashiers), Customers also had the option to approach cashiers
| directly, receive their order tickets, and pick up items
| themselves.
|
| This is not that technically interesting, but I liked how the old

| level, it dovetails nicely into most of the shortcomings of the

|
| On the technical level, I'm starting to migrate away from reagent
| (ClojureScript react wrapper). The first step was adapting
| preact/signals-react to support r/atom, r/cursor, and r/reaction.
| This has worked _beautifully_ so far and the whole module, with
| helpers, is less than 100 LoC. I'm irrationally excited about it,
| and every time I use any method it brings me a stupid amount of
| joy... especially since it's exactly the same API as reagent.
|
| For those curious, the next steps in the migration will be:
| upgrading to React 19 support once reagent ships with it (in
| alpha currently), then replacing the leaf components with hsx and
| working my way up the tree. No real code changes, just a lot of
| testing needed. Maybe at the end of it all, I can switch the
| whole app over to preact -- will be interesting to test the
| performance differences.
|
| As far as ideas I'm thinking about, I'm currently planning the
| next task in my head. This will be an (internal) clojure library
| that will hopefully have ClojErl (erlang), ClojureScript (js),
| and jank (C) interfaces, which means I'll be able to write
| clojure once, and run on the server, browser, and mobile -- all

|
| Here's how it works: Find a product (or suggest one), contribute
| to its testing fund, get detailed lab results when testing
| completes. If a product doesn't reach its funding goal within 365
| days, automatic refund. All results are published openly.
| Laboratory.love uses the same methodology as PlasticList.org,
| which found plastic chemicals in everything from prenatal
| vitamins to ice cream. But instead of researchers choosing what
| to test, you do.
|
| The bigger picture: Companies respond to market pressure.
| Transparency creates that pressure. When consumers have data,
| supply chains get cleaner.
|
| Technical details: Laboratory.love works with ISO
| 17025-accredited labs, test three samples from different

| I'm building an AI-native operating system for business, from
| first principles. It's called Simple (https://simple.dev).
|
| With 20+ years of experience building an enterprise software
| platforms, I have seen firsthand that trying to bolt AI onto
| legacy systems is an architectural dead end. It's like building a
| state-of-the-art 'smart penthouse' on top of a 100-year-old brick
| building. The foundation wasn't designed for the weight, the
| wiring can't handle the power demands, and you get a high-tech
| facade on a crumbling, inefficient core.
|
| We decided to build the modern skyscraper from the ground up,
| designing the entire system around three core principles:
|
| 1. A Unified State Machine: We started with a single,
| transactional data model and a core set of APIs that can
| represent any business object or workflow. Everything from a
| customer record to an approval process is a primitive in this
| system.
|
| 2. Language as the Primary Interface: Natural language isn't just
| for Q&A; it's a first-class citizen for commands. A prompt like
| "Create an app to track sales leads with fields for status, deal
| size, and owner, then add a 3-step approval workflow for deals
| over $50k" directly executes against the core APIs, modifying the
| actual schema and logic in real-time. No consultants needed.
|
| 3. True Agentic Execution: Our AI agents are given credentials to
| this same core API layer. You can delegate multi-step, stateful
| tasks ("When a new lead is assigned, notify the rep on Slack,
| schedule a follow-up in my calendar for 3 days, and generate a
| draft outreach email using our template"). The agent executes
| this by making the same API calls a human developer would, but
| with the flexibility to handle variations.
|
| For the nerds, here's the tech stack we're using to make this
| happen: The backend is built in Elixir; the BEAM VM's actor model
| and fault tolerance are perfect for managing thousands of
| concurrent agents and workflows. For performance-critical parts,
| we drop down to Rust via NIFs. Crucially, all custom logic --
| whether generated by an AI agent or a human -- is compiled to
| WASM. This provides a secure, high-performance sandbox, giving us
| language flexibility and near-native speed for all automated
| tasks.
|
| We're moving from a paradigm of "users hunting through menus" to
| "users delegating real work." It's an ambitious mission, and I'd
| love to hear what the HN community thinks of this philosophy and
| architectural approach.

|
| - Similarly have a quick, improved option for dealing with

|
| - Add some additional reporting that I'd like to see (as well

|
| - Finally (and most importantly but also most ambitiously)
| develop a view with some simple tools that helps users figure

| Technical approach: - AST-based pattern matching (moved from

|
| Business model experiment: Success-based pricing - only charge

|
| Early observation: Slopsquatting (AI hallucinating package names
