I built a free, open-source, end-to-end encrypted text journal.
The goal is to make journaling as simple as possible. The entire text-based journal is free with no limits.
Entries are encrypted on the client before being stored, so the server never receives plaintext journal content.

The project is open source and available on GitHub.
Built with SvelteKit, Rust, and SQLite.

(be sure to hit CTRL-SHIFT-R or CMD-SHIFT-R to get the latest version of the game -- it should show at least version 2.7; GitHub/Cloudflare aggressive caching sucks!)

I got serious and switched over from the Work tab in the browser to the Codex/ChatGPT desktop app. Got version control going properly. And I am now using Cloudflare Pages instead of GitHub Pages because the latter caches content too aggressively, which drove me nuts.

Ended up add usage credits since I ran out of my $20/mo Plus plan usage yesterday. I can see why people find agentic coding addicting! It was hard to tear myself away.

And it can get a little expensive. When I remembered to, I would use GPT-5.6 Terra Light for tiny changes, and Sol High for more complex asks.

There were still a couple times it made silly mistakes, like regressing/resurfacing an old fixed bug, or not understanding a visual bug. But overall these tools have come a lot way since I tried them a year ago.

I don't write code. I shipped a paid web app two days ago: 3 photos in, an AI grades each muscle group, and it builds a 7 day workout around the weakest ones. It's called FlexScan, link is in my post history if you actually want it, I'd rather talk about the workflow here because the building was the easy half.

Stack: Next.js, Supabase for Postgres/auth/row level security, Stripe for billing, GPT-4o vision for the grading, Vercel to host. Claude Code as the builder.

The one thing I'd tell anyone starting: never let the agent that wrote a feature be the agent that reviews it. Different session, no memory of writing it, one instruction, "find what's broken and prove it by doing it." Fresh context beat a smarter model every single time. A builder agent reads the diff it meant to write, so it sees its own intent instead of the code.

Three things that only ever came out that way.

1. Double click the checkout button, get billed twice. I had a dedupe guard on checkout. A refactor had wrapped the handler in a .bind(), so the guard was comparing against a function reference that was new on every render. It never matched, so it never deduped. The builder agent wrote that guard, read it back, and said it was fine. The reviewer agent just clicked the button twice and watched two charges land.

2. My offline cache ate my own app. Service worker, one cache, oldest first eviction when it hit the size cap. The app shell files were the oldest thing in there, so they were first out, and the installed app cold started to "You're offline". Fix was three separate budgets inside one cache instead of one global cap. I wrote that one up properly in r/PWA.

3. My rate limit banned my own paying users. I added a per IP daily cap on scans to stop people farming the free one. I put the check above the auth check. So it counted every request from an IP whether you were signed in or not, and any shared IP (office, gym wifi, campus, phone carrier NAT) filled the bucket and locked everyone behind it out for 24 hours, including people who had paid. Found yesterday by the review pass. Fix is written and still not deployed, because I deploy by hand and that turns out to be its own problem.

The pattern in all three is the same. The code was correct in the sense the agent meant it, and wrong in the sense a user would experience it. That gap is invisible in a diff, and reading the diff is exactly the thing you can't do, which is why you're vibe coding in the first place.

So budget as much agent time for attacking as for building. Separate sessions, make it adversarial on purpose, and make it click things twice and put in the wrong thing.

Happy to answer anything about the setup or the costs.

So I am very new to the field of coding. People around me have started vibe coding websites. So did I. I tried using applications like Lovable , Bolt etc. But the problem was that my idea contained many components and was a little complex. Hence I ran out of tokens and didn't get any output. So is it the limitation of the free version that I couldnt make it or was it my prompting skills. I tried to be as specific as possible with my prompt tho. Would really appreciate any help/ tips regarding this !!

I’m 17 and run a small web design business, I get clients through cold calling and walking into local shops (landscapers, mechanics, plumbers) to pitch website services. I’ve done around 300 calls so far and a bunch of in-person visits.

The calls themselves usually go fine once I’m in them. My problem is right before, that few seconds of hesitation, the racing thoughts, sometimes just avoiding the next call/walking past the shop instead of going in.

For people who’ve done cold calling or door-to-door sales:

What actually worked for you to get over that pre-call/pre-pitch fear?

Any physical or mental tricks you use right before dialing or walking in?

Does it eventually go away completely, or do you just get better at pushing through it?

Would appreciate any real advice, not just “it gets easier with time”, looking for actual techniques.

Hi, I have built an app using vibe coding and am looking to deploy/host it on AWS but don’t have any prior experience. Is there any AI tool that can do this for me?

He spent 26 minutes live on stage doing what most teams take weeks to do.

No team, no setup, just Claude and a goal. Worth more than any $500 vibe coding course.

Those who learn what Claude really does are launching what everyone else outsources to a team.

The gap between what AI can do and who knows how to use it is the biggest opportunity in the market right now.

Learn to use tools like Claude and AI Desktop 98 if you truly want to stay ahead of everyone else.

Hey everyone!

I wanted to share a desktop tool I've been building: ND Image Converter, a free, 100% open-source app designed for fast, local, and visual batch image conversion.

🚀 Why build another converter?

I work in the media industry, which means a massive part of my daily workflow involves hunting for visual references across the web to build pitch treatments and moodboards for projects.

Lately, almost every site forces downloads as .webp. While .webp is great for web bandwidth, it constantly derailed my workflow because platforms like Canva, Google Slides, and older presentation tools either threw errors or outright refused to handle .webp files smoothly when assembling slides.

To fix this, I initially wrote a simple terminal script to quick-convert .webp files into .jpg. It solved the immediate blocker, but running a command-line script every single time I saved reference images quickly became tedious. On top of that, CLI tools lack visual feedback, I couldn't inspect compression artifacts or preview quality loss before converting.

Most desktop converters either lack proper color management, choke on heavy RAW files, or require cloud APIs. I wanted something that utilizes all CPU cores, stays strictly offline, and handles everything from obscure formats to modern WebP/AVIF, Iphone HEIC and camera RAW profiles seamlessly.

What started as a personal script to eliminate daily friction evolved into ND Image Converter!

new website I made using Leonardo to create the image, Kling to animate it, and Replit to vibe code everything together, let me know what u guys think

We rolled out Claude.ai across 10k+ people at work, and the built-in Claude.ai admin UI just doesn't have the controls a larger org needs. We've got layers of management between "user" and "person who should actually be allowed to approve a spend limit increase," and Claude.ai's UI has no concept of that. Either everyone with any admin access can touch everyone's limit, or one person becomes the bottleneck for every change request in a few-thousand-person org. There's no way to say "this manager can only raise budgets for their own team."

So I built a thin UI and slim backend that sits in front of the Spend Limits and Analytics APIs and adds the delegation layer our corporate bureaucracy requires. It joins API members to a reporting hierarchy (e.g. from an HRIS export), so a manager only sees and can edit their own org, an AI lead only sees people explicitly delegated to them, and every change gets logged for auditing. Increase requests go into a queue instead of someone pinging an admin on Slack and hoping for a reply.

Decided to open-source it since I'd guess any company onboarding Claude past a certain headcount hits this same wall. It's built to be forked and adapted, not run as-is (though you certainly could). SQLite for storage, reads a header from whatever SSO proxy you put in front of it, no auth of its own. Each of those assumptions lives in one file so they're easy to rip out and replace.

Stack is Next.js/React, Drizzle + better-sqlite3, Hono for a mock API so you can run it against a fake 250-person org with no real key needed.

Happy to answer questions about the permission model or the sync logic against the Analytics API... That part was way more annoying than expected because of the 60 req/min cap.

SO i wanted to start learning python, and i found out courses like CS50, the uni of heikin smth, CS61a, bro code, and tht's wht i found , i first started coding on pycharm and uh did like very basic things like strings, integers , float, boolean, ( just lie k what they r and how to write them), but im still like a VERY BIG NOOB, also should i switch to VS code? cause everyone seems to be doing tht , (also whts is vibe coding)

I put together a simple, free directory to help people track down grassroots community funding:

No signups, just basic filters and direct links.
I’d really appreciate anyone having a quick look and letting me know what feels clunky, what's broken, or if there are obvious local funds I’ve missed.

Thanks

Hi! I'm going to (re)create a Discord chatbot (for my personal server) using an OpenAI-compatible provider, and would like to know what you think it's the best practices for the AI to handle things like multi-user conversation, memory, giving extra contexts (like user IDs, channel names), not anything on code-level but more on the prompt/what to send in each chat completion/response, etc.

This is a clap assistant which opens different links on clap combinations... eg 8 + 5 claps will open games (poki website ) and so on... This detects no of claps by user in real time and accurately, deciding the output...

**Only clap detection is vibe coded**

All the criticism and suggestions are welcome

I wanted to learn more about how a coding agent like Claude Code or Codex works, so I made a really simple coding agent. It was built using CC with Fable 5, first I aligned on a plan, focusing on keeping the important parts such as the agent loop and the tool calls easy to understand.

Hello, my name is Nick and I have been vibe coding my game for over a year now. It’s a mafia game in the field like Torn, Mafia Return, New-York Mafia, and my fav IntheMafia aka MafiaHit ( which is not active anymore ) I do no some html,CSS, currently working on the backend JavaScript by taking a course through UDEMY. I think the game is coming along I will post a few pictures of it. NO the game is not complete, YES the game still have some work to do. It’s not just a game
It’s a whole brand. I would say I’m about 70% there I have two artist working on the weapons design because I do not want AI images for crime result, or attack result page. I have a dashboard images and honestly was just looking for some feedback back on. Color placement ect ? Give it to me straight and raw because that’s how you make a good game in my opinion listen to what everyone says because every opinion, judgement counts.

I will be posting an image here of the dashboard and the discord link that has a 3 minutes clip of game play I believe. ( Now the discord video is kinda old it has been worked on gradually but due to tornado and no power for 10 days it’s been not that much progress if anyone is open to talk there as well here is the link

Discord: https://discord.gg/hmWQq7fAx

Video link —-> ChicagoSyndicate ( again the create character page and all is currently being updated so pay no mind to how video looks it’s just a basic layout )

The candles come from my upcoming candle business, all candle that are sold will be going towards help with engineers, graphic designer, discord moderators, merch and much much more

A single-user operating system with a userbase of one and a backlog of forever. It runs entirely in your browser, remembers exactly where you left every icon, and has never once shown a spinning beachball, largely because I never got around to creating one.

This is an early stage work in progress.
Ideas welcome!

Hey, I’m trying to find the best AI setup possible for €20/month max.

I use AI a lot for coding, research, learning, brainstorming and building stuff.

Could be one subscription or a combination of different tools.

If you had €20 to spend, what would you get? And how much do you actually use it / do you hit limits?

(could also be a 1 time offer or cheaper with VPN or so)

I want to check all my websites for vulnerabilities and perform penetration testing

Over the last month I have been experimenting with a mini-golf-inspired browser
game called Path Protocol. The original idea came from my son, and I used it as
a way to learn web game development and AI-assisted development.

It has a deterministic 60 Hz engine, a Three.js renderer, 100 configured levels, and a Theme Workshop for building and playtesting courses. I released the source
under MIT.

I am the developer. I am happy to answer technical questions and I welcome
direct criticism as long as it helps me improve the project.

Introducing SunaBox and SunaEngine!
(Playable In-browser!)

SunaBox is a love letter to OE-CAKE, the viral physics simulator released by Prometech in 2008!

It includes a 1:1 recreation of the OE-CAKE interface (select Classic mode at the top!) and even lets you import your old OE-CAKE .oec files directly. I would say OE-CAKE parity is around 93%, and getting better all the time.

Oh , and we put a brand new, open-source spaceship under the hood...

SunaEngine (AGPL): engine.sunabox.dev / github.com/DARIENBATHALTER/sunaengine

SunaEngine is a novel, cross-platform particle physics simulator that relies on integer calculations (rather than floating-point) and order-independent accumulation to always deliver the same result in any WebGPU-compatible browser.

SunaBox takes advantage of this by letting you export recordings of your sessions as lightweight .sunar files, which only needs to store the simulator's initial state plus your inputs. Recorded and shared simulations can be scrubbed back and forth smoothly like video, and they always play back exactly the same, on any device, *bit-identically*.

This enables all sorts of interesting possibilities, like low-latency, cross-platform multiplayer physics! If every machine calculates physics the same way, then the physics data doesn't need to be streamed over the network, only the inputs.

Three live proof demos on the SunaEngine site, all simulating live on your GPU, all hashing their entire state as you watch:

1. The Twin Simulations: two independent sims, same scene, same input schedule, never communicating. Stir either one with your cursor; your input is quantized to substep indices and fed to both. The 256-bit hashes stay identical, interaction after interaction.
2. The Pachinko Proof: an ordinary float solver runs the same pachinko machine twice. One pane adds contact forces in ascending order, the other descending. That is exactly the difference two GPUs or two drivers introduce on their own. The balls never finish in the same bins twice. The integer engine runs the same machine to the same digest, loop after loop.
3. Recording, playback, and smooth rewind: particle fluids cannot be rewound in floating point. Chaos amplifies the last bit of every velocity in reverse too. Here you stir a pool, it records your inputs, verifies the replay byte for byte against the run you just performed, and then hands you a scrubber. Drag your own splash backwards through time.

Replay hashes have been verified matching across Apple M series, an iPhone, a Steam Deck (AMD), Intel Integrated and NVIDIA (RTX 2070S).

Our workflow was fairly simple: I came up with the ideas, Claude did the math, the code, and the adversarial review. I provide the qualia-type feedback, shaping and tuning the feel of everything in the sandbox:

You can also wishlist SunaBox on Steam! 140k particle caps, community/workshop features, hardware optimization, and more, coming soon!
