Netsight is a network scanner and security toolkit I built solo in Swift 6 / SwiftUI, targeting iOS 26. It does live LAN scanning, device fingerprinting (OUI/DNS/HTTP), a force-directed topology map, on-device AI analysis via Apple Foundation Models, and CVE lookups against the NVD database.

Happy to answer anything about the architecture or the security tooling.

For anyone wondering, the app I'm working on is https://www.AppScout.co.

It helps people discover web and mobile apps from across the internet by showing them one app at a time. People like apps in order to get personalized app recommendations.

Tiny high-level programming language built in less than a month *without* any AI assistance as my first ever C++ project at 17.

- No dependencies
- Close to Python/NodeJS performance, in some cases faster (see benchmark)
- Tiny memory footprint
- Tiny executable size
- Incredibly modular. Pick & choose everything.
- Nones, Bools, Ints, Floats, Strings, Arrays, Maps (dict), & user defineable types*
- I/O, Math, File Managment, Time, Str/Arr Util, & full ANSI modules all included, most are embedded into the executable itself.

Why make this? I wanted a portable & embeddable language that was fully sandboxed, very memory efficient, & has all the essential high-level language features, all while being under 200KB in size. I have looked all over, the language I was looking for just didn't exist, so I made it myself.

I want to keep working on it & improving this because I know this is something a lot of people beside me would find useful, giving a star really helps

I've been building a side project called Portlio over the last few months.

The problem I wanted to solve was simple: I kept finishing projects, pushing them to GitHub, and forgetting to update my portfolio. By the time I started applying for internships, my portfolio was already outdated.

So I built Portlio.

It lets you:

• Connect your GitHub account
• Choose which repositories to showcase
• Generate a portfolio website
• Add context about your projects
• Keep your portfolio updated as your GitHub changes

Some recent improvements based on community feedback:

• Demo mode (no GitHub login required)
• Multiple portfolio templates
• Better onboarding
• Faster page loads (mobile Lighthouse: 90 on the landing page)
• Improved GitHub sync flow
• Better project storytelling instead of just listing repositories

I'm not really looking for design feedback anymore—I want to know whether this actually solves a problem for developers.

A few questions:

• Do you maintain a portfolio, or has it become outdated?
• Would you trust GitHub as the primary source for keeping it updated?
• What would stop you from using a tool like this?

You can try the demo here without signing in:

I'd appreciate honest opinions, especially from developers who've gone through internship or job applications. If you think this is solving the wrong problem, I'd rather hear that now than after launch.

I've spent the last few months building something and I'm finally at the point where I want to share it properly rather than just quietly hoping people find it.

The idea came from a frustration I kept seeing (and feeling myself): SQL tutorials teach the syntax fine but there's never a reason to care about the answer. You filter a table called employees, get a result, and nothing happens. Your brain doesn't bother keeping it.

I wanted to try a different approach. QueryCase teaches SQL through detective investigations. You get a briefing from Chief Fox (our mascot), a real database to query, and a mystery to crack. The JOIN matters when a suspect has an alibi. The WHERE clause matters when you're trying to find who entered the building at 22:13. The SQL is the tool for solving something, not the point in itself.

Here's what's actually in it:

• A structured learning path across 54 cases, going from Recruit through Rookie, Detective, Senior Detective, and Chief Detective. Each rank has drills and a level exam to pass before you progress.
• Sandbox mode where you can explore real datasets (IMDB movies, Spotify, sports stats, Steam games) and run whatever you want with no pressure and no mystery attached. Just free exploration against actual data.
• Everything runs in the browser using DuckDB WASM so there's nothing to install.

I'm a solo developer and this is genuinely early days. I'm sharing here because this community is exactly the kind of people I built it for, and I'd rather get honest feedback now than find out later I've built the wrong thing.

What's missing? What would make you actually stick with something like this versus what you've used before?

Any feedback appreciated!

I'm building OBridge — a platform where early-stage startups raise

capital through video pitch reels, matched directly to investors

who fit your stage and sector.

We're filling the final spots for our V1 launch. First 200 founders

get early access with special perks — priority investor matching,

founding member status, and direct visibility to our investor

network from day one.

Drop your startup below or grab your spot: https://joinobridge.com

What we need from you: your startup name, what you're building,

and what stage you're at. That's it.

For most of my life I tried to be someone else. I'd find someone I admired, decide they were better than me, and copy them. That mindset pushed me into a business I never enjoyed and only started because I looked up to one specific guy. It failed. I felt completely lost.

Around that time I was obsessively tracking my sleep with a Whoop, trying to optimize it. I kept getting good recovery scores. And I was still exhausted, yawning through entire afternoons, dead by 2pm. That's when it clicked: the score doesn't do anything. It just confirms you slept well or badly. Cool. Now what? Knowing isn't fixing.

So I built the thing I actually wanted. It takes the data your wearable already collects sleep, recovery, heart rate, and turns it into a daily protocol instead of another number. It tells you what supplements to take based on your metrics, predicts your most productive hours and gives you the exact time window when you should do deep focus tasks and light focus tasks, it tells you how much caffeine you have in your system left based on your first coffee taken and notifies you when you should take the next caffeinated drink for maximum productivity, it even tells you when to nap so your energy lasts the whole day instead of crashing and much more...

It's on the App Store as RizeAI https://apps.apple.com/us/app/rizeai-maximize-your-energy/id6762402079. i built by myself, it's early stage right now, and I want honest feedback, what's confusing, what's missing, what you'd never use. Tear it apart.

Is it bad that it took me over year to build this web app?

I'm sure experienced developers could have built something like this faster, but I learned a lot while making it and I also spent a lot of time iterating it based off of feedback, so I'm genuinely proud of how far it has come.

It's a checklist app for repeatable routines that only resets when you finish every task. Instead of daily streaks it's based on completion. One unique thing about this is that it resets automatically when you finish so you can complete it again immediately. I also added light gamification to help with the repetition of completing the same tasks over and over again.

Sometimes when you're doing the same routine repetitively, it's easy to for things to get overlooked. I originally built this because, as an aerospace inspector, missing a step is not an option.

It may not be the flashiest app, but I spent a lot of time making sure it can handle real routines, work offline, require no account, and keep data local on your device.
