Hacker News: Newest

We are building this to be a true Replit/Vercel competitor, but with zero vendor lock-in. You can build and develop entirely on our platform alongside our SOTA agent, but you own the code and can deploy it seamlessly to any 3rd-party host like DigitalOcean, Netlify, AWS, or your own VPS.

To prove the core agent's capability, we just ran it against the LiveCodeBench Lite dataset (Python split). Here is the breakdown over a blind 369-problem run:

    Total: 348/369 passed (94.3%)

    Easy: 138/141 passed (97.9%)

    Medium: 152/156 passed (97.4%)

    Hard: 58/72 passed (80.6%)

(Note: We achieved that 80% on Hard by engineering the agent's constraints to strictly prioritize optimal time complexities like O(n log n) over brute-force O(n^2), avoiding the Time Limit Exceeded errors that usually trip up standard wrappers).

But we aren't just building this for the tech. My co-founder is a Palestinian refugee currently living in the Gaza Strip, and we are launching this to drive immediate humanitarian impact. 100% of the profits from 11 months of the year from this platform will be donated directly to support Palestinian refugees.

The agent is this good already, but I have a roadmap of architectural ideas to make it even better. Right now, I'm looking for fast angel funding, compute sponsorships, or strategic partners to help us scale this ASAP.

I would love any feedback on the platform or the agent architecture. If you are an investor or want to support the mission, my DMs are open on X, or you can reach us at univenceai@gmail.com.

Show HN: OpenDeck – DIY MIDI Platform Based on Zephyr RTOS

somemisopaste — Wed, 22 Apr 2026 20:44:42 +0000

This is OpenDeck, my own platform for building custom MIDI controllers. I've been working on it for more than 10 years, and now I've made the biggest change so far - rewritten the entire codebase to make use of Zephyr - RTOS with which I've been working professionally for few years now. This now allows me to support many newer boards, complex features and also to modernize the codebase in general. I've been limited on all fronts before.

The platform itself allows for simple building and configuring of custom MIDI controllers - main reason for that is because it requires no coding. Load the firmware on the board, configure it via web configurator and you're good to go. The amount of configurable features is also huge. I do have extensive documentation which covers usage, configuration, flashing of various boards, customization of own boards etc. All available on GitHub.

The platform supports a large number of various boards - not only my own, custom designs, which I sell, but boards like Raspberry Pi Pico 1 and 2, STM32F4 Discovery, Teensy 4 and 4.1, nRF52840DK etc. Lots of choices. Before Zephyr, I rolled my own HAL for various platforms and YAML-based peripheral configuration, both of which is now replaced with Zephyr and its various subsystems and tools, primarily device tree. I must admit however I do not enjoy C at all so most of the stuff I use is wrapped in an external C++ library (zlibs) used as west module on which OpenDeck depends. The project itself is written in C++20. Currently I'm using Zephyr 4.4 and its MIDI 2.0 driver in MIDI 1 compatibility mode, as well as WebUSB for firmware updates, so this is a fairly modern stack.

Show HN: FourthSpace – Bridging Social Media with Your Social Life

adra_1010 — Wed, 22 Apr 2026 20:39:58 +0000

Hello I’m Aditya.

Me and my co-founder are on a mission to eradicate social media addiction and loneliness off the earth. There’s no reason for us to turn to digital companions of any kind, or be in social isolation, when we can and should be having direct discussions with each other everyday.

We're building FourthSpace as a solution to these issues.

One of the biggest problems many people are dealing with right now which is preventing them from hanging out with others is the cost of going out, buying drinks, transportation, etc.

We've built a beta version of a feature to solve this.

If you go to our website and launch an Audio Content Lounge(at the bottom of landing page), you can watch Youtube videos synchronously with your friends or family. You don’t need an account to test it out.

Once you’re in you need only copy the link by tapping the ‘share’ button and sending it to whoever you want to join you. And to add a YouTube video simply tap the ‘+ Youtube Video’ button and paste in the links of the videos you want to watch together. Pausing and playing a video will be synchronous.

We hope this audio content lounge feature can help people who are dealing with this problem be able to more easily spend time with others on a daily basis and not have to worry about all the logistics of going out.

My friends and I love watching NBA highlights together in them and recently we’ve been discussing upcoming playoff games together in the lounge’s while watching related content together even though we are in different parts of the country.

Additional Features Inside of FourthSpace(after you sign-up and log-in):

* A social media content globe as opposed to a feed, designed to give you the ability to choose what you consume. The globe is broken up into topic areas, where you will only see content for the specific topic area you choose to consume content in. Click on a topic to zoom into a topic area or use pinch gesture on your track pad to zoom in and out of the globe. * We don’t have much content uploaded as of yet but you can be amongst the first. Kind of like the early days of YouTube. * Content system is not designed for discovery or time spent on platform but instead for building community.

* Dedicated “Friends” section. If you add someone as a friend and they accept and you upload a picture to FourthSpace they will see it in their friends area. No other content will be in this area other than picture or video posts from friends. Also no likes or comments or followers so there is less incentive for people to chase clout. Like original instagram without the vanity.

* Built-in time tracker and notifications whenever you’re spending too much time ‘scrolling’ or in this case moving around the globe. Every 5 minutes you will be invited to instead ‘touch grass’.

Plus a whole lot more.

Keep in mind we are in early beta and a lot of the features within the globe aren’t fully functional yet. So please be patient with us as we continue to build. But the audio content lounges are functional and hopefully can help people spend more time with each other already.

Please read our manifesto at the bottom of our website if you have the time as well.

If you have any comments, questions, or suggestions feel free DM me on Instagram @aditya.rao.iv

Thank you.

Show HN: Cosmo – Desktop agent with generated UI

row0 — Wed, 22 Apr 2026 20:33:31 +0000

Hey there! I’m Shiyuan, a recent college grad working on this.

Cosmo lets you interact with your computer through generative UI.

Examples:

- Type “github action status for my website” → desktop dashboard of all the action run statuses

- Speak “create a linear issue” → instant UI on desktop to select the assignee, labels, etc.

It is integrated with GitHub, Vercel, Jira, Supabase, Linear, Posthog, Google Workspace etc. so people can see charts, make edits, and complete tasks through these generated interfaces.

And everything happens on your desktop, it’s not another app window you have to switch to. We hope to use generative UI to kill app windows :P

The concept is still early, and generation speed may be suboptimal (meant to be instant, faster than human navigation on traditional UIs). But I’d love to hear if it can boost productivity somewhere in your workflow. Feedback is greatly appreciated!

We mapped unauthenticated Vector DBs exposing corporate AI data

echelongraph — Wed, 22 Apr 2026 20:21:12 +0000

We noticed a massive spike in misconfigured RAG pipelines leaving vector ports open to the public internet with zero auth. We built a live map pulling OSINT data to visualize the scale of the leak: https://echelongraph.io/ai-threat-map

It highlights why perimeter security is failing in the AI rush, and why we are building EchelonGraph to process telemetry with zero-knowledge encapsulation at the source. Happy to answer questions.

Ask HN: How are you handling data retention across your stack?

preston-kwei — Wed, 22 Apr 2026 19:58:37 +0000

For people building SaaS with data across multiple systems (S3, DBs, caches, etc), do you actually have a clean way to manage retention/deletion across all of them? (Especially when each customer has custom policies)

Or is it more a mix of lifecycle rules, cron jobs, and manual cleanup?

How are you doing this today? I feel like this is a blocker in enterprise deals when selling to regulated industries.
