I've been building HX Code Studio, a browser IDE for a small programming language called HX. The goal is to make Arduino-style programming easier for kids and beginners.

For example:

• digitalWrite() D.write()

• setup() / loop() fun set / fun loop

I'm trying to find the right balance between making programming easier and keeping concepts that beginners will eventually need when they move to standard Arduino/C++.

Hi,

I am new to the site and joined here to promote a free movie web app I developed. Want to know where and under what category to post it.

I am the founder of Slydr. We are targeting to simplify gifting process. Currently operating only from India. With Slydr, you can gift anyone, anytime. Without needing their address.

Now with Slydr, its possible to send a gift to your reddit friend, PH friend, online date, without having to worry about their address. After making the payment, a gift link (or code) gets generated, which the gift sender will share it with the recipient. After reviewing and accepting the gift, the recipient will provide the delivery address directly on the website, which will not be visible to the gift sender.

Hey everyone! I'm an indie developer based in South Africa building GUARDIAN 2.0.

I got tired of legacy safety tools relying on slow, expensive SMS notifications, so I re-architected my platform to run real-time crash telemetry straight through WhatsApp while bridging directly into physical home alarm hardware (like Olarm, Paradox, and IDS).

Really glad to join the PH community! Excited to connect with other makers working on IoT, mobile sensors, and developer-led projects. What are you all currently building?

Hey everyone, I'm Abhay

I'm a software engineer contributing to OpenObserve, an open-source observability platform (Rust backend, Vue frontend). Most of my work is on the frontend design system and developer tooling lately I've been deep in a large component migration and building Claude-powered PR review automation with GitHub Actions.

One thing I'm genuinely trying to figure out: for those of you using AI in your code review or CI pipelines, where has it actually saved you time vs. added noise? I've found it great for catching style drift and missed edge cases, but I'm still tuning how much to trust it on architectural feedback.

Happy to share what I've learned about open-source contribution workflows or setting up AI code review in GitHub Actions if that's useful to anyone. Looking forward to being here!

I ve spent a lot of time looking at how businesses manage customer conversations, and one thing kept bothering me.

Customers might message a business on WhatsApp, Instagram, email, webchat, or somewhere else entirely, but the business often ends up managing each conversation in a different place.

Hi from Austin, TX!

In the last few years, I've been moving around different enterprises and startups. Pretty different worlds but somehow they all got me more interested in one particular topic - the way people work together.

Mine starts with a number too: 220 seconds. That's how long it took, on a real
dependency advisory, from pressing a button to an open pull request the alert
landed, an embedded coding session opened already holding the repository and
the package, edited an isolated checkout, and the runner pushed the branch. I build Celmis: one tree-sitter symbol graph across a set of repositories, read
by four surfaces cross-repo Q&A with citations re-checked against the files
on disk, a pull-request reviewer, generated documentation, and an MCP server.
Self-hosted, AGPL-3.0, one machine under docker compose. The number I'd rather not hide: 17th of 50 on a public PR-review benchmark. I
audited all 79 findings the benchmark scored as false positives against the
source and published the verdicts 33 turned out to be real defects the gold
set missed. A wrong number said honestly is worth more than a good one said
quietly. Launching Thursday, 00:01 PT.

I'm Abiting, a Taiwanese developer and creator, graduate of National Yang Ming Chiao Tung University. I've independently created a range of free online tools, with the hope of benefiting more people through technology.
