Currently a one-man side project:

https://laboratory.love

Last year PlasticList discovered that 86% of food products they tested contain plastic chemicals—including 100% of baby food tested. The EU just lowered their "safe" BPA limit by 20,000x. Meanwhile, the FDA allows levels 100x higher than what Europe considers safe.

This seemed like a solvable problem.

Laboratory.love lets you crowdfund independent testing of specific products you actually buy. Think Consumer Reports meets Kickstarter, but focused on detecting endocrine disruptors in your yogurt, your kid's snacks, whatever you're curious about.

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 production lots, detect chemicals down to parts per billion. The testing protocol is public.

So far a couple dozen products have received some funding, six products have been fully funded (five product results published, the sixth is at the lab as I write this!)

You can browse products, add your own, or just follow specific items you're curious about: https://laboratory.love

Looking at the tofu reports, I really don't know what to make of them. Is there a way to give more meaning to them for the average person? Also, I'd love to see a sort by "almost funded" option.
I love this idea. I imagine it could be extended to other types of testing - for example, I've always wished there was a way to more readily verify whether the contents of vitamins were as specified on the label.
I LOVE this idea. Tangentially, a more pimitive case: in trying to recycle or reuse jars or carboard containers food comes in, I wish there was a simple service for ranking brands. For example, some jam jars have labels that can be immediatey removed - others tear and stick to the jar. Similarly, some brands use excessive plastics and packaging, others less so.
I love this!

I keep telling my euro-friends that food and health regulation could potentially be enforced by the free market more effectively than by corruptible government, and this is a perfect example of this.

I'd want to see all products I can buy in there, with all possible chemical, ingredients and nutrients, and clear indications of good/bad, a little bit like in Yuka. You should partner with them maybe even!

Wow, great idea, simple website and hopefully a positive impact, not often you see all three in one project :) Good job!

I'm guessing it's limited to US products and US labs? Would love something similar in Europe and/or EU, but it isn't clear if you're limited to US/North America right now, would be nice if it was a bit clearer up front :)

Really cool project. A quick note, I had to dig in your FAQ to find your definition for LOQ:

> "What does 'LOQ' mean in your results? > > Limit of Quantification (LOQ) is the lowest concentration we can reliably measure. Results below LOQ are marked "<LOQ" - this doesn't mean zero, just below our measurement threshold."

IMO this definition should be on every results page, since most of the pages have more LOQs than anything else.

This is great. I thought about a different model even before plasticlist: make a subscription and test various products, but people will have a number of upvotes based on their sub streak. They vote for food to test, and then you show results to everyone subbed. Kind of like what examined does, but they do deep dives into medical topics for subs. I think this model will work better than the one you currently have. Awesome project anyways!

It is extremely weird to me that countries don't do that on taxpayers money and show the results publicly, this is what they should do.

A couple of suggestions:

The completed entry should include the date of the test results, so currency can be judged,

Ideally the completed entry should contain a scan of the full test report from each of the accredited laboratories.

This is great. We definitely need something like this.

Where are the safe levels limits to interpret test results? This would be a small addition that would make any of the results interpretable. I had to open the PlasticList website to get the baseline safe thresholds for each chemical and to do some rough approximations.

I'm working on a system that helps surgeons make precise bone cuts during knee replacement surgery. Believe it or not, manual cuts are still the standard in that type of procedure. Robotic systems exist but they are very costly, big, and actually add time to the surgery (bad news when you are under anesthesia and your leg is in a tourniquet).

It uses 4k stereoscopic capture and bunch of ML models to match bone position with sub-millimeter precision. The surgeon screws a metal base piece into the bone, and we detect where that is in space. Then, a Stewart Platform adjusts another part that is placed onto the base. The robotic adjustment allows the base to be placed in a ballpark area, with the robotically-adjusted piece oriented in the exact spot where the surgeon needs to cut.

The net result is a robotic system that is many times cheaper than the least expensive incumbent, decreases surgery time significantly, reduces error, and basically "just works" as opposed to requiring a ton of training. We are debuting at a tradeshow in October.

"Google maps but for old maps": https://pastmaps.com

This is a solo startup that I've been working on for 2 years now. It's a labor of love and I'm very lucky and thankful that it's big enough to surprisingly pay all of our bills. Still constantly feeling FOMO over all of my startup buddies working with AI and LLMs while I plug away at old maps and GIS .

It gets ~80K MAUs and just slowly and consistently is growing organically through word of mouth through history focused communities. I'm currently playing with expanding the coverage internationally as I still only support the US which is a wickedly fun project.

In 2023 a friend and I started a monthly dinner club with the goal of eating around the world without getting on a plane. We gather once a month at a restaurant on Long Island for a meal focused on a theme or region of the world. The meals are around 10+ courses and include a drink. We work with the restaurant to craft a menu that is as close to authentic to the region as possible.

Our first dinner was with 13 friends and has since grown into a group of just about 1,000 members. Last year we generated around $140k for local restaurants on off nights (dinners are on Tues and Wed when business is slow).

Now we are working on evolving into more of a lifestyle brand for people who love food. I'm currently working on our clothing line and new site, which we quietly launched a few days ago (there's still a few odds and ends to finish): https://www.deadchefssociety.com. Would love any feedback!

I’m working on an ISBN database that fetches information from several other services, such as Hardcover.app, Google Books, and ISBNDB, merges that information, and return something more complete than using them alone. It also saves that information in the database for future lookups.

Mostly because I’m working on a personal library management service called Shelvica to solve my own problems[1], and none of those services provided all the information on a book. One might provide the series, the other might provide genres, and yet another might provide a cover with good dimensions, but none provided everything, so I decided to work on something of my own (called Librario).

While Shelvica is the focus, Librario could become its own thing in time, so I don’t mind the sidetracking.

I also plan on having a “ISBN Search” kind of website that feeds from that database as a way to let users search for information about books, which then feeds the service’s database, making it stronger for Shelvica.

I open source everything I make, but I’m still wondering if these will be open sourced or not. I’ll probably go with the EUPL 1.2 license if I do decide on open sourcing them.

[1]: My wife and I have a personal library with around 1800 books, but most applications for management are either focused on ebooks or choke with this many books. Libib is the exception, but I wanted a little more.

I finally collected the courage to release my operating system into the wild:

https://news.ycombinator.com/item?id=45400006

I'm super curious if anybody will pick it up and do something useful with it. This was a couple of years of my life and I absolutely loved working on it but having a child put a hard stop to such entertainment for many years. Now, a good 30 years later I finally found the time to resurrect it.

I'm not sure yet if I am going to do more work on it or leave it as it is, it's good enough to give someone new to OS development a running start and a foundation to build on.

I've been working on a 3D voxel-based game engine for like 10 years in my spare time. The most recent big job has been to port the world gen and editor to the GPU, which has had some pretty cute knock-on effects. The most interesting is you can hot-reload the world gen shaders and out pop your changes on the screen, like a voxel version of shadertoy.

https://github.com/scallyw4g/bonsai

I also wrote a metaprogramming language which generates a lot of the editor UI for the engine. It's a bespoke C parser that supports a small subset of C++, which is exposed to the user through a 'scripting-like' language you embed directly in your source files. I wrote it as a replacement for C++ templates and in my completely unbiased opinion it is WAY better.

https://github.com/scallyw4g/poof

I launched Quiet UI this week:

https://quietui.org/

It prioritizes accessibility, longevity, performance, and simplicity.

With the autoloader, one script tag loads components dynamically without downloading the entire library. (npm also available.)

Theming uses color-mix() and OKLAB to create uniform color palettes from a single CSS property. Adaptive palettes are used for dark mode.

All form controls are form-associated via ElementInternals and work with native validation APIs (required, pattern, etc.).

Dialogs, popovers, tooltips, etc. use Popover API for top-layer access without having to portal or hoist.

Some of the more fun components include: Joystick, Stamp, Mesh Gradient, Flip Card, Random Content, Intersection Observer, Typewriter, Lorem Ipsum, Slide Activator

The library is free for personal, educational, non-profit use. Commercial use requires a license.

Hi HN, I am working on Circuitscript, a language based on python to describe electronic schematics/circuits: https://circuitscript.net/

Recently, I have released a simple IDE (called the Bench) to try Circuitscript online: https://bench.circuitscript.net/

The next steps are to create more schematics with Circuitscript as examples to test the limitations of the language and to generate PCB designs with KiCAD. The Circuitscript tool (currently only the desktop cli tool) is able to generate KiCAD netlists and this can be imported into PCBnew.

The motivation for creating Circuitscript is to describe schematics in terms of code rather than graphical UIs after using different CAD packages extensively (Allegro, Altium, KiCAD) in the past. I wanted to spend more time thinking about the schematic design itself rather than fiddling around with GUIs.

The main language goals are to be easy to write and reason, generated graphical schematics should be displayed according to how the designer wishes so (because this is also part of the design process) and to encourage code reuse.

Please check it out and I look forward to your feedback, especially from electronics designers/hobbyists. Thanks!

Working on orbital dynamics code for my PhD in astronomy, written in rust, it can accurately calculate the positions of all asteroids/comets to within a few meters. Today I am adding a new numerical integration method which should enable me to predict orbits from observations.

https://github.com/dahlend/kete

I'm working on modeling the motion of observed dust particles coming off of comet 67P, here is are some example 3d plots:

Example of rocks ejected from one position and their possible motions: https://dahlend.github.io/67p_beta_dust.html

Trying to determine possible orbits from a set of observations (the straight lines): https://dahlend.github.io/67p_dust_orbit.html

Shout out to pyvista for making these great 3d plots possible, a little less ergonomic than matplotlib, but it can export directly to html.

I'm working on Typegres, a new data layer for the modern stack (TypeScript + PostgreSQL).

My take is that for years, ORMs have hidden the power of PostgreSQL behind generic, database-agnostic abstractions. This made sense in 2010, but now it's a bottleneck.

Typegres rejects this. It's a "translator, not an abstraction," designed to express the full power of PostgreSQL (all statements, built-in functions, etc.) in a type-safe TypeScript API.

The latest killer feature my take of "object-relational mapping done right": class-based models with methods that are actually composable SQL expressions. This lets you extend your tables with expressive logic and fully-composable relations.

It's easier to show than tell. Take a look: https://typegres.com/play

I've been making and selling my electronic social battery pin badges for a while now (https://hortus.dev/products/social-battery) and I'm expanding the range with seasonal versions like a Christmas mood badge, and a halloween themed ghost badge that's coming soon. I'm lucky enough that these projects have gone down well and are making enough money to fund some more complicated (and expensive) projects that I wouldn't have otherwise had the guts to try. Currently I'm working on an RGB digital sand timer with customizable timing sequences so that you can use it for things like the pomodoro technique - I have a working prototype and at the moment I'm experimenting with interfaces for setting the sequences. I wanted to use a combination of buttons and an accelerometer for this but it's not as intuitive as I'd like so I may end up making a small smartphone app to configure it.
Building an iOS app for metronome sequencing to get faster at playing guitar and reaching "shred" speeds at different subdivisions/time signatures in a single sequence. Planning on adding accuracy indicators and scoring so rushing or dragging can be easily identified when finishing a saved routine. I.e., some post-routine metrics.

I've been playing guitar for a little under 6 years and ran into the common problem among many intermediate guitarists fall into, which is stagnating into a plateau at a certain BPM.

The most effective solution I've found is to take the top speed hit playing a chunk of a lick and simply increase it 20-50 BPM past that limit, attempting one's best to stay in tempo. Regardless of how sloppy it sounds. Then roughly halve that increased addition of BPM, it will become relatively easier to play. For example, if you are stuck at 120 BPM, upping it to 150 BPM with sloppy attempts, then dropping it back down to 130-140 BPM.

I've gone cleanly from alternate picked 140 BPM triplets to 220 BPM triplets in two months after being stuck at 140 BPM for over a year with this method. Sometimes even hitting 280 BPM triplets when I have the focus and time for it.

Even then, I want a more consistent, and variable way of customizing a practice session using a metronome from a hobbyist perspective without using a DAW. With a simpler interface for doing so. As well as encourage with said method above for other guitarists in the pursuit of speed.

Release engineering for FreeBSD 15.0-RELEASE. Major releases are always a lot of work, but this is probably the biggest release in 20 years due to the new base system distribution system landing. (We're switching from "here's a tarball containing everything" to "here's 500 packages", with resulting changes in the build process, download/update mirrors, installer, etc.)
On the side, custom coloring books for kids using nano banana, started with a project for my son, and its a little janky for some photos but have had some interest already: https://bespokebooks.io. I think it needs to be a phone app to really work for most people though, so that's next on my to do list besides some prompt tweaking.

Notebook to do it yourself here: https://github.com/dbish/bespoke-books-ai-example

I think there are a lot of really fun projects possible now in the child book creation space, particularly as you build tools that they can use themselves (like adding voice interfaces to building a book or story).

This is outside my 996 job of AI Agent/Assistant infra + ops :)

I’ve been suffering from migraines for the past year and the health system hasn’t been too helpful in diagnosing why. I’ve got some meds, but they’re expensive and not without side effects. So I’m building an app to try and figure out how to avoid the triggers in the first place.

https://dotsjournal.app

Sort of like a digital bullet journal. You setup some rows of events you want to track, then just tap for when/if that events happens. It’s already helped me spot certain triggers for my migraines, which I can now minimize. My wife has been finding it helpful to diagnose sleep problems. I think it might be super helpful to others with trying to understand lifestyle choices and how it impacts their wellbeing.

About to roll out the beta. Hoping to have a full release by the end of the year.

It’s my first iOS app in 8 years! Learning SwiftUI after UIKit has been quite the shift.

Working on a webapp for critically think with others about a problem.

The idea is that you build a diagram that contains all the details about the problem and people's thoughts on it, and it's organized in such a way that it's easy to just keep refining, down to the smallest detail. So you build this concrete, shared understanding, and move it forward and forward, until hopefully y'all can make some best decision to improve the situation.

There's a lot to do. Currently working on UX to allow hiding intermediate nodes and still have indirect edges drawn. Want to add an LLM integration to generate/update diagrams via natural language, which I think will help a lot with usage barriers to using the app.

Happy to get any feedback :) https://ameliorate.app/ https://github.com/amelioro/ameliorate

I'm working on Small Transfers (https://smalltransfers.com/), a payment platform that makes it very convenient for SaaS / API makers to provide a pay-as-you-go model to their customers.

You can charge as little as 0.000001 USD per request. The platform uses our own system for tracking usage, which is settled through Stripe. No crypto, tokens, or wallets.

If combined with subscriptions, the pricing can work similarly to mobile plans, where monthly plans become cheaper above a certain usage threshold.

Looking for more developers to try it and share feedback.

Resources: integration guide (https://smalltransfers.com/merchant/docs/integration-guide), a quick walkthrough (https://youtu.be/WQW5fiUFNRk), a Next.js template (source code: https://github.com/smalltransfers/nextjs-starter, live demo: https://nextjs-starter.smalltransfers.com/), an AI template (source code: https://github.com/smalltransfers/ai-starter, live demo: https://ai-starter.smalltransfers.com/).

I’m building a daily word puzzle game with a twist!

In Tiled Words you rearrange tiles to solve clues and rebuild a broken crossword.

You can play a demo at https://tiledwords.com - it’s free and web based so it works on whatever device you’ve got.

I’ll be officially launching on October 19th at the Portland Retro Gaming Expo. You can sign up to be notified on launch. Starting then there will be a new puzzle every day!

So far I’ve gotten really positive feedback and have around 100 people signed up to get notified. It’s been a lot of fun to build!

Non tech, but I started a sports beverage company with my brother and a neighbor. We are based in South Florida.

My brother and I grew up playing sports and remember the simplicity of home-made drinks we'd take to games that blew the likes of Gatorade out of the park. We aim to replicate the simplicity of home-made drinks with simple ingredients.

https://www.drinkiso.com/

Our whole value-add is based around the fact that most sports drinks or hydration drinks contain a lot of junk. We are opposed to the bullshit catch-all that is "natural flavors" and believe in product transparency and honesty. Our products straddle the line between fresh-pressed juice and sports drinks. Our prices are definitely on the higher end, but with scale, we can lower them.

We currently are in growth mode - and currently are one of the best selling products in the top boutique gym chain in the Miami area, as well as going strong in all SoFLA Equinox locations (except for the WPB location which isn't open yet).

We do sell online but shipping is a PITA as overnight shipping costs for cold products are astronomical. When we find a cheaper solution so I can ship around the country, I'll let everyone here know :)

Based in South Florida (Miami-Dade, FtL, West Palm)? DM me and let's meet up!

I'm on the cusp of launching an interior design software I have built with my partner (she's the interior designer, I'm the coder).

https://inspec.design

My read of the industry in terms of software is that it's split into 3 groups:

1. Interior visualisation (basically 3D renders) which largely target the what-if amateur market

2. Big, clunky and old software tools for professional interior designers working on huge projects, which works well but has that universal sort of mild dislike to strong disdain depending on the person

3. New players who want to replace the old clunky software

Seeing this, we decided not to try to overthrow the old all-powerful project management solution, but rather to replace a single process in the interior design workflow. And of course to do it very well.

I'm creating Comper, an infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the company etc), languages used, security issues. There's time-travel, think Gource for all software in your company, and maybe the most fun: a GeoGuessr for code. Select the repos for your team (or if you feel confident, of the entire org), you get a snippet and have to guess where it is. The plan is for LLMs + tree-sitter to analyze all the code and show relations to other systems, databases etc.

My initial announcement got the top spot in "What are you working on? (February 2025)" https://news.ycombinator.com/item?id=43157056 but now I'm a lot further, there's a website https://comper.io and the company is getting incorporated within two weeks.

Last week I showed it off in the Feeling of Computing Meetup (fka Future of Coding) - the recording is here and the reactions were extremely positive https://www.youtube.com/watch?v=3-rg-FPZJtk

I'm opening the private beta soon, where I mix using the product with consultancy, to get better customer feedback. Not sure if that will work, but I don't have all the features yet for bottom-up adoption.

https://github.com/little-book-of/maths/blob/main/books/en-U...

I've been working on a book called "The Little Chronicles of Mathematics, Data, and the Mind of Machines", this is a 100 sections journey from counting stones to thinking silicon. This book is more like a storybook for curious builders. I wrote it for people who love see how things connect, how math become language, how data become memory, and how machines learned to reason. If you enjoy clear ideas, and big arcs of history, this book is for you.

I'm currently building Visirya, an app that helps people record their night dreams and transforms them into short videos and written journals. The bigger goal is to use this dream data to create dream cartographies, essentially maps of recurring themes, emotions, and symbols—to uncover patterns and insights across dreams over time.

So far, we've built the video generation and dream journaling features. The app is live on TestFlight, and we're preparing a major update soon that includes a new better UI, and dream questionnaire to help with pattern recognition and dream mapping.

Would love to hear thoughts, feedback, or connect with others working on similar intersections of tech and the mind! If you're interested in trying it out, you can find the TestFlight link on our website: https://visirya.com

I started a newsletter that tries to recreate the original magic of stumble upon. To feature cool random stuff from across the internet.

I believe the old internet is still alive and well. It's just buried under a mountain of shit.

https://randomdailyurls.com/

1. A port of linq-to-sql for Typescript (https://github.com/webpods-org/tinqer) allowing queries like:

  const activeAdults = from<User>("users")
    .where((u) => u.age >= 18)
    .where((u) => u.active === true);
It mostly works.

It'll go into webpods (https://github.com/webpods-org/webpods), which is like firebase but with hash chains underneath.

I'm trying to make an RF lightning detector small enough to trivially add to my motorbike.

I live in Viet Nam, and driving through bad storms this time of year is pretty miserable, and they happen fast and are local enough that weather prediction is not terribly useful.

There are a lot of problems with EMI. Lots of ungrounded brushed motors everywhere that make the RF bits hard. If I succeed, I'll publish the PCB designs.

I've also got some educational products in production right now, about Vietnamese history. I'd share a link, but my website probably can't handle the traffic right now.

I'm launching a new product for my clock-making business: https://DigitalHorology.com

None of my clocks tell the time.

They're all fully automatic GPS-enabled timepieces. For a couple of years I've been developing, hand-making, and selling these clocks that track the moon phase, the sun's position, etc.

My new idea is the tide clock "NautiKron." It's getting a lot of interest from US coastal buyers.

Building an app where 1 pushup = 1 minute of scrolling allowed [1]. We've fiiinally started to grow and reached a whooping $30k in the last month!!

I was literally thinking about quitting in August. My motivation is now at an all-time high - some users have done >8k pushups :)

As always, the key has been the marketing (10M views on Instagram). But we have to improve the product to make people love it even more. So the roadmap is more full than ever.

Very much a hobby, but I'm working on a Pinterest alternative built on ATProto called Scrapboard[1]

The Bluesky ecosystem is a really great platform to build social media on and with Pinterest being overtaken by AI content I figured I'd give it a shot. There is definitely not as much content there, but it is of much higher quality and the culture of providing alt text on images really makes search work rather well.

Just an old hobbyist these days. I'm finishing up the written manual portion of a "breadboard helper" for playing with (learning) electronics. The current "helper" I am finishing up gives you instructions (and an explanation) for wiring up over a dozen transistor logic circuits with the aid of a small PCB + breadboard [1].

Inspired by Forrest Mims III, Don Lancaster and the "75 in 1" style electronic project kits my mom got for me for Christmas when I was a kid.

I hope to sell them and then probably never recoup my investment.

(I'll leave it as an exercise for someone clever to figure out what circuit is being depicted in the photo.)

I’m building https://www.kidcarekit.com, a Rails SaaS for family-run daycare centers that still juggle spreadsheets and phone calls. It wraps waitlist management, enrollments, and Stripe billing into a single dashboard with Tailwind + Hotwire on the front, Devise for auth, and Azure Blob for logos. Solid Queue handles scheduled jobs like weekly tuition and late fee automation so owners get predictable cash flow without hand-cranking invoices, while MailerSend keeps parents in the loop.

Right now I’m polishing the onboarding flow so new centers can import families, configure their billing cadence, and connect Stripe in under ten minutes. Next up is richer analytics (occupancy tracking and revenue health) and rolling out a guided setup for late fee policies. If you’re running childcare ops or know someone who is, I’d love feedback on the workflow pain points you still feel daily.

Full-time indie dev breathing life into next-gen terminals [0]. This is my lifelong career ambition.

If you can't afford early access, please email me and I'll grant you a free copy: I need all the feedback I can get!

I love these threads, and always learn or pick up something new.

From my side, I've been working on a multi-lingual first words book for a baby. None of the published books have our mix of languages (which is fair enough, I don't think there is much of a market for it!) and so I decided to create our own. It's just images and then the word translated into three different languages alongside it (like a typical first words book). I used Google's AI for the images, and it has done a surprisingly good job of creating baby friendly images, with enough detail to spark interest.

The other tangential benefit is that I found it awkward to speak in my mother tongue, but having this book helps break that by having me speak in that language and then leads to it feeling much more natural in other contexts with babies.

This is not very technical project (though if I had the time it could easily become a fun project where people select their unique mix of languages and the book gets produced).

If anybody is in a similar boat and wants to produce their own version for their mix of languages then please let me know and message here - I will happily share the Canva file with you (you'll just need to write in the words yourself). (This idea of sharing is inspired very directly by Derek Sivers 'Sharing' idea [0])

I started a company to grow unlimited eggs from stem cells, based on the work from my recent PhD. This will solve nearly all female infertility and help prevent genetic disease.

I've been working non-stop on my game development tutorial website:

https://raizensoft.com/tutorials/

Currently it mainly focuses on libGDX which is my most favorite framework. I prefer code-centric approach because that's how game development should be in my opinion.

Most of the tutorials are just pure coding with algorithms explanations. My goal is to build one of the most resourceful website for libGDX because it's quite underserved at the moment.

In the future I may expand to other code-centric frameworks and more general game development topics, let's see how it go.

I'm pursuing my vision of "music-i18n": Open source music software that works for microtonal music and worldwide musical cultures.

It's not a from-scratch effort, quite the contrary: I'm trying to tie in existing music standards (MIDI, MusicXML, SMuFL, MEI, etc.) and ensure that FOSS systems (MuseScore, Verovio, smaller components) implement enough of those standards to support music-i18n.

Sometimes, this also includes extending the standards themselves when they are not fully capable of representing some non-mainstream musical aspect. For example, MusicXML lacks the ability of representing multiple accidentals per note (whereas MEI does), which is a must for microtonality.

I started down this path around 2018, as a music player who got interested in arranging Arabic songs in a "Real Book" style. It opened a giant rabbit hole that I'm still far from having fully explored.

Now and then, I collaborate with other devs who are interested in adjacent topics. I would love to hear from some of you here!

As an entry point, I recommend checking out the "progress report" I wrote last October: https://blog.karimratib.me/2024/10/01/music-grimoire-progres... - I'm currently drafting this year's update. My main demo is at https://blog.karimratib.me/demos/musicxml/

Building https://fallinorg.com/, a Mac app that organizes your files.

It looks inside each file to see what it’s about, then moves it to the right folder for you.

Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.

It already works with PDFs, text, Markdown, and many other file types. Next I’m adding ePub, and later Microsoft Office and iWork support.

If you have messy folders anywhere on your Mac, Fallinorg can help.

I'm working on a new unconventional form of computing called "temporal computing" - as both a PhD and as a fledgling business. The idea is to use delays in time (It's called interval modulation) as the data. I have a video explainer on YouTube https://youtu.be/rXbzJxThgig?si=FYMleAgZ0GMNEqk9. It's a long road building your own computational model and I'm currently looking at Turing completeness, and models of multiplication.
Building Evidentia – platform for scientific knowledge that never gets published

Science's most valuable output never gets published. Negative results, failed replications, protocol details etc. all vanish into the file drawer. This means that the public body of knowledge is slow and also often wrong.

The cost: 70% of researchers can't reproduce published findings. Only 6 of 53 landmark cancer studies replicated. Industry wastes $28B annually re-validating work that doesn't hold up.

We're building a platform to capture what gets lost. Scientists share the details papers omit: failed antibodies, critical protocol tweaks, replication attempts. AI + a graph DB structures it into queryable data. Contributors get DOIs so it counts as real academic credit.

Been testing with beta users for 2 weeks. Opening up waitlist now: https://evidentia.bio/

Key challenge: will scientists share without traditional publication incentives? Early signal says yes (especially younger researchers), but needs to scale.

Feedback welcome, especially on keeping it alive (avoiding the "data graveyard" problem) and monetization.
