I am building https://framebench.dev/ in my free time. It comprises of a bunch of utilities aimed at common workflows found in automotive industry. Some highlights:

- Easily parsing UDS, ISO-TP protocol CAN frames

- Parsing CAN-DBC files

- Building CAN Frame Payloads based on messages in a DBC file.

This is really early stage. Any thoughts are welcome.

techtalksweekly•2mo ago
I've been working on Tech Talks Weekly which is a free weekly email with all the recently published Software Engineering podcasts and conference talks in the past 7 days.

https://techtalksweekly.io/

Every week I pull all the new talk recordings from hundreds of conferences (Devoxx, KubeCon, PyCon, QCon, LeadDev, JSNation, and many more) as well as podcasts. I feature the ones I think are must-watch with short summaries written by me, then include a list of everything else uploaded that week.

It started as a personal project to fix my own messy YT subscriptions and RSS feeds, and now 7,300+ people read it. I also publish fun extras like “Most Watched Talks of 2024” which made it to the HN front page.

If you watch software engineering conference talks or listen to podcasts, you might find it useful. I’d love to know what you think!

I'm building a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. We just won silver at the Big Indie Pitch competition as well!

- Currently in free Early Access with 18 competitive mini-games.

- Players use their mobile phones as controllers (you can use game pads as well!)

- Everything is completely web-based, no downloads or installs are necessary to play

- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!

- In the future we plan to open up the platform for 3rd party developers (and Gamejams!) as well. We take care of the network connectivity, controllers etc.. 3rd party devs can focus on developing cool multiplayer mini-games without spending an eternity with networking code and building the infrastructure.

Interested in your thoughts, would you play something like this? Feedback is much appreciated!

I've been working on a no-code multiplayer game editor. The idea is to let anyone create multiplayer games in a few clicks without writing code—and share them instantly.

You pick a template (platformer, tower defense, battle arena, etc.), customize it through the UI, and get real-time multiplayer with up to ?? players—no networking code, everything hosted.

The platform handles all the classic game systems out of the box: AI behaviors, combat, inventories, save/load, live leaderboards.

Technically, the engine just reads a config file and renders it for players. I've built all the foundation blocks that interpret the config. Once that's solid, I'm planning to add LLM generation—but foundation first.

I'll soon be onboarding game designers to stress-test the editor/engine. Still polishing templates so people have a good starting point, but it's functional and I'd love feedback!

Try it: https://craftmygame.com

Morale, mostly.

AI summaries have halved the traffic to the website I live from. My income is fine, but working for half the impact, knowing that it might get halved again is depressing. It feels like throwing resources - days of my finite life - at a war that I will lose.

Concretely, I am writing a guide about German citizenship and updating hundreds of slowly aging guides about immigration Germany. I am also collaborating with others to get better data about the housing market to help immigrants figure out their future housing costs.

I just finished adding Paywall as a Service functionality into https://gethly.com, which is a hosting and sales platform for digital content creators. This allows creators to host their content on their own without having to vendor lock themselves or anything like that. Best part is that the minimum price if any content is 1 cent due to how the platform works.

I am not sure what the next feature will be but this one was something I was looking forward to add.

I'm creating KeyPears, a password manager with support for decentralized Diffie-Hellman key exchange.

https://keypears.com

The basic idea is alice@keypears.com and bob@example.com have public keys exposed, enabling Diffie-Hellman, enabling end-to-end encrypted communications for sharing secrets. This enables company-to-company secret sharing, e.g. environment variables, without requiring that both companies use the same common service provider for password management. The network architecture is modeled after email.

Still a work-in-progress at this moment.

Building https://localhero.ai, automated on-brand i18n translations that run in your CI pipeline.

Right now I'm working on better .po/gettext support, based on feedback from an early customer. With gettext you usually keeps source strings in the actual source code. So I'm building a workflow where non-technical people (PMs, designers) can edit translations in the web UI and then easily generate a PR with both code changes and translation file updates. Trying to make translations work smooth for both automated CI pipelines and PMs/designers who don't live in Git, when translations are checked into the repo. Also going through my network, talking to devs and localization folks to understand what could be improved in their orgs for translations.

I truly, with passion, hate JIRA.

So, I'm building mooomooo, which is my idea of what it means to replace tools like JIRA, linear, and such with a unified data model that can adapt to solo devs, small teams and huge orgs so I don't have to manually move tickets to done.

I hope I can do my first release soon :)

I'm building epanet-js[0], a local-first web application for simulating water network.

The goal is to replace clunky, expensive enterprise desktop tools (which often charge $10k+ for a wrapped version of the open-source US EPA engine). We want our version to be frictionless: login optional, runs entirely in the browser, and saves files locally to your device.

We are using the Functional Source License (FSL) to keep it sustainable while remaining open.

A simple 50/30/20 budgeting app built on manual entry.

I found AI/automated trackers just meant i started to ignore everything. Research also suggests manual tracking trumps automated/ai tracking. You actually need to do the manual work to understand your finances well.

I’ve been working on a custom RTOS for Cortex-M for the past 10 years: https://github.com/raphui/rnk It started as a way to learn RTOS internals, and over time it has grown into something with lots of nice features. I’m even using it in a dirtbike anti-theft tracker I am building. Also, 2 months ago, I did a weekend challenge to build an embedded software parameter DSL and compiler. Its goal is to let firmware developers define configuration values, thresholds, constants, and other application-level parameters in a structured, human-readable format, and compile them into binary data that the firmware can directly use. https://github.com/raphui/epc

Happy to get any feedback :)

I'm building a manually curated catalog of videogames made by the HN community. Currently I've added data up to the end of 2023. Now I'm working on adding more data and evaluating a free newsletter to notify users when new games are added to the catalog. Currently at about 400 visits/month.

You can browse the catalog at these addresses:

I've spent several years (since Covid) developing an ad-free website with 50+ solitaire/puzzle games.

I've gotten some feedback from HN already and now trying to fix things (rewriting the engine for 4th time). Hoping to add some more hundred games soon!

I'm also wondering what it is missing – any particular game or mode (e.g. daily games or tournaments)?

Started working on a training plan builder after getting frustrated with trying to use an existing service (trainingpeaks) and not finding the controls intuitive enough without being a coach in their system.

I wanted something local and offline first + 10-20% better than excel, think I'm missing a few features other might find useful, but it works for my needs which has been great.
