Last night I actually also started playing with firebase studio, though the app I prompted isn’t even doing save of the document properly. I figure can’t be me but will try again and work through the errors.
And playing drums, must get better
Reactivity can update the state of the notebook automatically, so you don't have to keep track of which cells to execute again. Side effects are managed to make it easier to reason about while maintaining reactivity and ability to interact with the outside world.
I know, it sounds crazy.
In a month or so, I’ll be sharing some news.

Upstream SFML: - 10000 draw calls (!) - My fork: 1 draw call
This (opinionated) fork of SFML also supports many other changes:
- Modern OpenGL and first-class support for Emscripten - Batching system to render 500k+ objects in one draw call - New audio API supporting multiple simultaneous devices - Enhanced API safety at compile-time - Flexible design approach over strict OOP principles - Built-in SFML::ImGui module - Lightning fast compilation time - Minimal run-time debug mode overhead - Uses SDL3 instead of bespoke platform-dependent code
It is temporarily named VRSFML (https://github.com/vittorioromeo/VRSFML) until I officially release it.
You can read about the library and its design principles in this article: https://www.vittorioromeo.com/index/blog/vrsfml.html
You can read about the batching system in this article: https://www.vittorioromeo.com/index/blog/vrsfml2.html
You can find the source code here: https://github.com/vittorioromeo/VRSFML
You can try out the interactive demos online in your browser here: https://vittorioromeo.github.io/VRSFML_HTML5_Examples/
The target audience is mostly developers familiar with SFML who are looking for a library very similar in style but offering more power and flexibility. Upstream SFML remains more suitable for complete beginners.
I have used this fork to create and release my second commercial game, BubbleByte. It's open-source (https://github.com/vittorioromeo/VRSFML/tree/bubble_idle) and available now on Steam: https://store.steampowered.com/app/3499760/BubbleByte/
BubbleByte is a laid-back incremental game that mixes clicker, idle, automation, and a hint of tower defense, all inspired by my cat Byte’s fascination with soap bubbles.
A trailer is available here: https://www.youtube.com/watch?v=Db_zp66OHIU
You can search for full or partial rows and see the whole query lineage – which intermediate rows from which CTEs/subqueries contributed to the result you're searching for.

Also learning to deal with having very little to no money atm.
the process of creating APIs for testing and automation should be as easy possible. the tools that exist nowadays for this purpose aren't good enough IMHO, which led me to build it.
It's an website who's goal is to make it easier to find apartments/hotels/etc that fit your housing preferences (starting with places that are close to the people and things you care about). It's flagship feature is the ability to make heatmaps of cities based on your preferences.
Since February I've slowed down on feature development temporarily as I try and find a way to sustainably increase it's popularity and learn what's the most important thing to focus on next.
Hoping to share a first version of it soon. It’s been absolutely fascinating digging into Postgres internals!
What they are. their capabilities, and their and risks and write about it on my Substack
Encyclopedia Autonomica: https://jdsemrau.substack.com
On that note, I also curate a list of resources around AI Agents that fit my narrative:
It works like a run club, where you have to make a review first to see other people's reviews.
I am currently implementing watchlists, comments and a mural to make it feel a bit less lonely. Right now I like the UI but it feels to lonely.
But reviews are everywhere, good ones too so it will be a hard chicken egg problem to solve.
Official release is Cinco de Mayo, I'm very excited!
It has hierarchical clustering, rolling correlation charts, a minimap, time series data detrending, and 2D matrix virtualization (to render only visible cells to the DOM).
It has up to 130K matrix cells and correlates up to 23.5M time series data points.
What I'd love to be working on: Try to initiate a high voltage arc through the air to a target device, and modulate it to send "Data over Lightning", like Alyx does in Half-Life 2. It won't work the way it does in the game, but I'd it's an idea I've had for a long time and I'd love to prototype it some day.
Next feature is search.
I would love to see some UI/UX improvements like split view where the map is on the left and the news reading/scrolling happens on the right reading pane instead of on the bottom while horizontally scrolling.
You could even use AI/LLM's to summarize the most important news from each country etc.
thinking about taking dancing lessons instead, maybe afrobeats.
The first is a preventive maintenance and calibration tracker (https://pmcal.net) that was born out of my day job as an engineer in small business manufacturing.
The second is an AI engine for pulling structured data out of incoming email (either via IMAP on your email server or via SES). If you think of the engine that powers TripIt, they had to write about 10,000 different ingestors for each airline and hotel and travel booking site. With a structured output AI, the need to write specific ingestors goes away.
I'm giving myself 18 months- it's been super fun so far!
The only self-hosted option I found was wger.de and while it looks great, it's a bit too much for my needs. I want something lightweight (so as not to hog resources on my cheap VPS) that does what it needs to do and nothing more.
It's been a while since I've done web dev, so I'm going to try out Deno (TypeScript) with htmx.
I may also finally finish implementing WebMentions support too as a kind of comment section.
I may also work some more on my long-term relaxation/creative maze generation and solver project.
At work, I keep putting off yet more refactorings that are required because of poor/missing requirements and non-technical leadership of the project.
It wouldn't be so bad, but part of this "new" project involves communicating with some awful SharePoint """database""", as well as a poorly designed real database (it has multiple values in one column, not even with any standard, just sometimes there's extra numbers I need to parse, sometimes not - just lots of this type of crap repeated everywhere), and the worst development/deployment experience I've ever had to deal with in ~10 years.
To write code involves Remote desktop to what was a single core VM (and much protesting gained me... one extra core) to Windows Server 2016 meaning most modern/nice developer tooling isn't supported, and deployments are all done by copy pasting files over yet more nested remote desktop sessions.
Sadly there's no real way of automating any of this, every suggestion is always a "default no", again most of the tools I'd need for this won't run on Windows Server 2016, and even if I worked around it the stakes are way too high for "It's easier to ask forgiveness than it is to get permission".
The turn around time for even a small change is huge because of this mental burden, it's a complete slog to get anything done.
So I guess what I'm saying is I've been casually looking around at jobs this month.
This is why I always stress the importance of being able to work on my own projects, because otherwise, I'd have burnt out.

just waitlist for now, but I have posted some demos on my twitter - https://x.com/rogutkuba/status/1915533678207262931 - https://x.com/rogutkuba/status/1915226139812839690
I'm curious: what are your must-haves in a note-taking application?
Unlimited undos. Even if I deleted text a year ago, app must bring it back. Ideally something like git, with branches and auto-commits.
Currently working on adding a manga mode and Netflix auto-captioning
People hate AI generated content, but the quality is actually good and Google likes it.
Escape rooms are honestly... almost always a let down but the concept has a lot of potential and there are some really neat ones that standout like this local one where you pilot an airship https://www.portlandescaperooms.com/steampunk-airship
Once I build the best escape room on the planet, I can consider selling the tools.
Also working out the logistics of offering a microgrant to award people who want to make movies like this!
Talo makes it easy to add systems that traditionally need extra non-gameplay build time like authentication, player analytics and game stats.
Right now you can drop Talo into your game or use the API directly. Importantly, I’ve made Talo easy to self-host and you can point the Unity package/Godot plugin to your own Talo instance.
I am suggesting this since you said you want to better understand functional programming. Category Theory, as mathematicians look at it, is an extremely abstract field. If you want to do pure math related stuff in Category Theory, and only then, I would say important prereqs are Abstract Algebra and Topology. I believe the motivation for Category theory lies in Algebraic Geometry and Algebraic Topology, but you definitely don't need to be an expert on these to learn it.
Launch soon! Drop a comment if you want early access

Regardless of if I target macOS or Linux first, this would be a pretty full time endeavour on my part. I could wait until the commercial use licenses of the Windows version sustain me enough to be able to work on this full time, or try to raise a Kickstarter for $X00,000 to be able to quit my 9-5 and work on porting full time for a year or so
In what I believe is still the spirit of the question though, I discovered Maltese these week and have added it to my casual study. It’s a Semitic language (closely related to Arabic), written in the latin script, with about 40-50% of its vocabulary being Italian/Sicilian based. It’s become my new obsession
I signed up, but now it's asking me for a "reference language" (which is a little ironic because it tells me this in English lol). I guess I'll play with this later.
In the process of adding stuff like euclydian sequences, and trying to figure out how to generate melodies. Been considering using something like a simple markov probability from a bunch of jazz standards, but also starting to read more music theory behind it.
It's a programming project but it's directly related to me trying to figure out music. So not a random sequence of notes in scale or not. The idea is more to generate backing tracks or song starters.
Strong recommendation: Hire a teacher. Even with experience playing four instruments, and when I decided to learn another, I still hired a teacher.
Let me know if you have any feedback or feature requests.
Using a dataset-based implementation would require me to have a backend, which is out of the scope of this project. Right now, I'm generating random IPv4 addresses, but if I were generating random IPv6 addresses, I would have to go the database route. For that, I would use our free IPinfo Lite dataset: https://ipinfo.io/lite
My colleagues actually developed an extremely fast algorithm to select truly random IPv6 IPs from a series of CIDRs, which is what you see reflected in our dataset.
Let me know if you have any feedback or suggestions for me, please.
I'm generating random IP addresses on the frontend, then making an call to our free API to validate the "realness" of the IP addresses — mainly to remove bogon IP addresses, non-routable IPs, and IPs from large ASNs (national ISPs, the DoD, car companies, etc.).
Our free API supports 1,000 requests per day from unique IP addresses, so there shouldn't be any issues for low usage. However, if we get more power users who enjoy the game, I’ll switch to our Lite API service (which is also free, https://ipinfo.io/lite) to validate IP addresses, as it supports unlimited requests.
Let me know if you have any feedback for me :) I made it mostly by "vibe coding", I will write a post about the whole process of it.

A merge conflict resolution tool integrated with GitHub. Now working on a solution for preemptive conflict detection and a smarter/simpler merge queue.
Are you building a Google Trends like tool?
I've been using / testing out such tools lately for market research + discovering new ideas etc.
I’m still looking for a new SaaS idea, so if you have something you want to partner on do reach out. Preferably Rails or Go. Previously I built stuff like https://getbirdfeeder.com/
In parallel, I'm building an exercise generator "Jazzln" [2] to help me practice.

A few examples of what it can currently do:
- Automated data backup: Listens for Nomad job events and spawns auxiliary jobs to back up data from services like PostgreSQL or Redis to your storage backend based on job meta tags. The provider for this is not limited to backups, as it allows users to define their custom job and ACL templates, and expected tags. So it can potentially run anything based on the job registration and de-registration events.
- Cross-namespace service discovery: Provides a lightweight DNS server that acts as a single source of truth for services across all namespaces, solving Nomad's limitation of namespace-bound services. Works as a drop-in resolver for HAProxy, Nginx, etc.
- Event-driven task execution: Allows defining custom actions triggered by specific Nomad events; perfect for file transfers, notifications, or kicking off dependent processes without manual intervention. This provider takes in a user-defined shell script and executes it as a nomad job based on any nomad event trigger the user defines in the configuration.
Damon uses a provider-based architecture, making it extensible for different use cases. You can define your own providers with custom tags, job templates, and event triggers. There's also go-plugin support (though not recommended for production) for runtime extension.
I built this to eliminate the mundane operational tasks our team kept putting off. It's already saving us significant time and reducing gruntwork in our clusters.
Check out the repository[1] if you're interested in automating your Nomad operations. I'd love to hear your thoughts or answer any questions about implementation or potential use cases!
Really like to look of the product page!
I do want to give them a little privacy and it gets to the appropriate level. Like restricting some apps at certain times, access to chrome but not xhamster. Locking it for certain periods of time and having them request more screen time past 4 hrs/day. Locking the phone whenever they've barricaded themselves in the room the whole morning.
I don't necessarily mind that they're watching YT or TikTok and such. I just want to kick them out of the doom scrolling cycle every now and then.
My main challenge has been making meeting detection more robust -- it currently uses both mic and camera activity, which led to a lot of false positives. In the next version I’m switching to mic only (the camera caused most of the noise) and I’ve added a way to identify which app is using the mic, so users can exclude non-meeting apps.
I’ve also added plenty of small tweaks throughout to make LookAway even less interruptive. I’m excited for the next release!
I am also working on the last few remaining issues of Hyvector, of which some are surprisingly difficult to solve and AI unfortunately cannot help me a lot.
Sounds basic, and it is, but I've yet to find any open source project (let alone product) that does this.
All I want to tap a button, talk to the little guy about how to update my document, and see the changes flow. I guess Claude projects or similar might do this but I'm making it more for friends and family. Current use case is keeping track of a house renovation project going on.
- there are lots of expenses still to be made (fertilizer, pesticide, salaries), which may not be worth it if germination is under certain threshold
- if detected early, there is still time to plant another grain or to fill up the missing plants (requires precision seeders and seeding maps)
- is a very good proxy for yield estimation (farmers often trade futures even before they have harvested)
For the purpose I have created a dataset (a collaboration between my employer and Sofia University) and published it in order to enable scientific collaboration with other interested parties. Still working on the dataset annotations.
https://huggingface.co/datasets/su-fmi/sunflower-density-est...
I wanted a library to store my own prompts once and retrieve it in multiple locations (i.e. Try something on claude desktop and then once I wrinkle out the edges, load it in Roo code or claude code and use it.) Give some variables to the prompt and creating infinite versions of same prompt by providing the value. Or having the versions of each prompt.
Currently I have the landing page, soon (In max 10 days) I will make it live for everyone to use.
Instead of masonry I would like to work on time of flight cameras. But the day has only 24 hours :-(
I am purposefully not doing chain loading or multi-stage to see how much I can squeeze out of 510bytes.
It comes with a file system, a shell, and a simple process management. Enough to write non-trivial guest applications, like a text editor. It's a lot of fun!
Not quite done with it yet, but you can see the progress here https://github.com/shikaan/OSle and even test it out in the browser https://shikaan.github.io/OSle/

The idea is to build scanning databases, file systems, buckets, etc. for static keys and credentials while allowing users to add new file types and parsers.
I also published the list of url schemes / universal links on GitHub: http://github.com/sxp-studio/app-list-catalog
(Minor note: The Setup Tutorial says, "Swipe right to continue" when the user actually swipes left.)
A few released apps for now that are iOS/macOS, with some exciting more things in the pipeline.
If you’re a photographer who has frustrations with current mainstream photography software (whether capture/edit/publishing), I’d also love to hear from you - you can find me as Héliographe on (mastodon,bluesky,threads,x) or just email me at contact@heliographe.net :)
I'm trying to capture a sense of fun, wonder and connection through these tools which I feel has been lost in recent times with remote working.
You might ask why use Pocketbase at all, and I'm not sure anymore. I suppose the dashboard is great, built in auth is great (although I've had to write cookie middleware to make it SSR anyway). I wish there was a lightweight Pocketbase/Supabase style "backend in a box" setup that didn't push the whole client library directly communicating to DB paradigm.
https://github.com/ncruces/go-sqlite3/tree/main/sqlite3/libc
Collecting the data helps with recording engine performance, tyre ages, best lap times but is also really useful for recalling how well each setup performed for future reference.
I’m deliberately doing this all in a very low-tech way as my son will be creating a more polished version for a school project. We’re front-running that a bit to give him a good dataset and explore various ideas.
On that note, they do Python in school. For the backend it will be SqlLite and Flask. Any suggestions for the front end tech? This will mostly be forms- and grids-based so nothing sophisticated needed, but some simple client-side logic (e.g. validation, geolocation, simple stop watch) would be good. Ideally this would be python as well. We could use WebAssembly but am wondering if there is a suitable framework that does the is out-of-the-box.
No app required!
We took all of the complexity of issuing MIFARE DESFire enabled NFC credentials and made it extremely simple.
