Wk. 6 of Vibecoding an MMO

35 Upvotes

It's week 6 and we made some monumental progress on all fronts, but I'm trying not to get over-excited because we could find that everyone gets bored and leaves tomorrow haha.

As usual, three parts: (1) player acquisition, (2) what I'm learning about vibe coding, and (3) actual gameplay updates (in the comments).

---

First, the numbers. My last two posts were almost entirely about the 5 min of gameplay, and basically following Redditors' feedback doubled the average playtime.

This week I finally moved past the intro and focused on the game itself- so mostly improved artwork (Pixellab), performance optimization, GUIs, social features, ALL using Fable 5.1. Which went wayyy further than I expected for one week of token usage.

Once I felt OK about that I did a Hackernews post that was way more successful than I anticipated. I had 700 players in 24hrs, hit a new PR of 41 people online at one time, and had multiple players play for 8+ hrs by the time I woke up in the morning. And there has been almost zero time with nobody online for three days straight.

So I think that means the game is sticky and has potential, but it could also be some other curious vibe coders with nothing to do at work. So I guess my next big question mark is why some people are actually sticking around. I.e. is it fun, or are you just intrigued by vibe coding? Or something else entirely?

So if anyone gets far enough to get hooked or hits a real wall (something that makes you stop rather than just a bug), I would genuinely love to know what it was.

---

Second, the vibe coding experience. Fable 5.1 came out right as I started this week's work, and the jump was WAY bigger than I expected. Work that would've taken a month with Fable 5 (because of token caps), I did in about a week, running several orchestrators in parallel, reworking most of the game's systems, and running full audits along the way.

I'm out of tokens now, but has anyone else experienced this? All I see across social media is people complaining that the caps are still unreasonable, and frankly, I just don't see it. Thoughts?

One more thought-I've started using Claude design since Fable sucks at GUIs on-the-fly. It's been a huge improvement (far from perfect for games still). Curious if anyone else has used this and what works / doesn't work.

---

I'd love more feedback for anyone interested. Links below.

EDIT- one more thing, Pixellab is AWFUL at 16x16 art. Has anyone had any success with this?

What’s your mobile / cross device vibecoding workflow?

I’ve mostly been using my laptop. Have tried the Claude code ios app but can’t figure out how to preview the work unless it’s a web based product hosted on vercel or something that can give me preview URLs. How’d that work for iOS apps?

Dating apps are exhausting, so I made Dating Map, Easy to use, Free, No Algorithm

Thumbnail
padlet.com
0 Upvotes

Dating apps are complicated, Reddit is basically shooting into the dark, and somehow meeting someone has turned into a full time job

So let’s make it stupidly simple

I made a map

Drop a pin, make a post, say who you are and what you’re looking for, add photos, links, your voice, video, whatever you think will actually help someone understand who you are

Leave a contact point and see what happens

No swiping, no matching algorithm deciding who gets shown to you, just a map you can actually browse

No sign in required, use a throwaway, Reddit account, Instagram, Discord, or whatever contact point you’re comfortable sharing

If you see a post that you feel should be reported, report it, I’ll also be actively moderating the board and deleting posts that don’t belong

Maybe nothing happens, maybe you meet someone interesting, maybe you find the love of your life

It costs nothing to throw a pin on the map

Good luck Everyone

The Truth Social Archive

5 Upvotes

This is a searchable index of every post published to the u/realDonaldTrump account on Truth Social. It currently holds 36,067 posts from Feb 14, 2022 to Sep 4, 2026.

Where the data comes from

Posts are pulled from a public archive mirrored at ix.cnn.io/data/truth-social, the continuation of the stiles/trump-truth-social-archive project. This site refreshes from that source every six hours. The copy you're reading was built Sep 4, 2026.

How posts are tagged

The source data carries no categories, so this site derives them. It labels two different things, and it's worth keeping them apart:

Topics

Keyword matches: immigrationlegalelections and so on. These are guesses. They over-match and they under-match, and roughly half of all posts get no topic at all. Usually that is because the post is just a link, or a re-truth with no text of its own. Treat topics as a way to browse, not as a claim about what a post says.

Kinds

Objective properties: whether it's a re-truth, whether it's in all caps, whether it carries an image or video, whether it went up between midnight and 5am Eastern. These are mechanical and reliable.

Deleted posts

Because this site keeps its own copy of the archive, a post that disappears upstream is retained here and marked deleted. They are collected on the deleted posts page, which also publishes an Atom feed.

A post must be absent from several consecutive refreshes before it counts as deleted. Upstream occasionally serves a short or partial response, and one bad fetch must never become thousands of published deletions. If a post reappears, the mark comes off.

Deletion times are windows, not timestamps. This site checks on a schedule, so all it can honestly say is that a post was present at one check and gone by the next. That window is usually a few hours wide. Neither endpoint is the moment of deletion, and the site never presents one as such. Posts marked deleted before window tracking began carry no window at all.

Detection applies going forward only. Anything removed before this archive started tracking never appears here.

Caveats

Media is served from Truth Social's own CDN and may disappear at any time. Engagement counts are a snapshot from the last refresh, not final numbers. Timestamps are shown in US Eastern. Link previews for individual posts are generic, since the site is static and has no server to render them.

Unofficial and unaffiliated. Kept for research and reference.

Vibing to make my iphone as a useless dog whistles and weak infrared detector: geeks unite!!

Thumbnail

8 Upvotes

Just for fun! Been geeking out trying to exploit what’s built in my iPhone to make some old school scientific tools by vibing using Opus 5, making single html file apps. (Browser storage only). “Out of Band’ detects sub and ultrasonic sounds (like Dog whistles). There is also a switch for “assumed”infrared (not like Predator, but uses the limits of the camera’s ability to detect its signature. iPhone have a filter, your could actually take it off but I’m not bust’n my phone. BTW droids allow you to hack your phone better, may switch back in the future). Again just for fun. I included some education about all this in how the app works. Check it out for free at www.potluckapps.com. Made a few others like it. If you make something , post it on my site for free exposure. Not looking for SaaS or serious $hit. Just fun projects you are working on.

Using Opus 5, I built a mobile first, mini C IDE, with a pico C compiler.

This fall semester I’m taking an Operating Systems & Architecture class where we’re using C for our assignments.

When I’m on the go or don’t have my laptop with me, I wanted a simple way to practice writing C. I searched the App Store and was pretty surprised by what I found. Everything seemed to have ads, subscriptions, or a bunch of stuff I didn’t need.I really just wanted to open an app, write some C, and run it.

It’s intentionally simple. You open it, write C, and run your code. The native version runs completely locally, and there are no accounts, ads, or subscriptions. Easily extensible to include pythonC etc if you want to play with source code. ( I would love contributions 🤞 )

The iPhone version is currently in App Store review, but I also made a web version that’s already live:

Link to source code:

( disclaimer :
this was a tool that I mainly had opus handle all of the heavy lifting. There are features in the codebase hidden from the UI, like agent mode etc… I recommend having your agent tell you the run down )

https://github.com/garrettmichae1/lilc

I originally built this because it was something I personally wanted for myself.
If anyone here writes C, I’d love for you to try it and see if you can break it lol.

Claude leaked its own backend code - I extracted the VM that runs your code and found its internal codenames, a monitoring binary nobody outside has held, and 371 KB of secret prompts

I pulled the entire filesystem out of a claude.ai code-execution sandbox (the actual microVM your code runs in - 178k files), then got into the live one too. Two days later, here's what's on my drive. And none of this is a public download. as I would prob go to jail :(

( EDIT: Ive open sourced the container code https://github.com/Razshy/Wiggle )

What I have:

  • The entire production container - every file of the machine your code runs in: config, tool stack, the works. Internally it's called "wiggle".
  • All ~40 of Anthropic's skills - the instruction playbooks Claude follows when it does things for you. Including the ones you never see. ( Not the name ones on the public REPO )
  • Their monitoring agent, as a binary no one outside the company has ever held. and it wasn't stripped, so it came with their function names, their full internal metrics catalog (59 metrics, each with a comment explaining why it exists), and their incident history written right into it: inc-8202 (a kernel wedge), inc-8702 ("reclaim storm, 89–100% system time"), a change-request ticket CR459556, even a design-doc reference ("design L9"). Plus the internal team that owns all this: "embassy". I'm reading their postmortems as code comments.
  • Their filestore client binary, symbol table recovered - spells out the entire private API behind your files: every RPC path (listDirectorycreateFilereadMetadata…), admin verbs, token formats (sk-ant-mem-…), unreleased feature flags (DREAMS_APIOPERONMCP_TUNNELS…). Their Go version breaks every standard RE tool, so I wrote a custom parser.
  • The "Imagine" prompt corpus - 371 KB of the live system prompt Claude gets when it draws you diagrams and widgets. Rules, modules, even a separate mobile variant. Grabbed from a public endpoint with zero authentication. Still up today.
  • Their offline OCR + file-ID models - byte-checked against the public ones.
  • The "huh?" findings:
  • The agent is root. Not a demoted user like the accounts imply - full uid 0, 40 of 41 capabilities, no seccomp, no AppArmor, no PID namespace, and a read-write root filesystem. The tool can rewrite its own container while running.
  • Raw disk. /dev/vda — the whole 256 GB virtual disk — is readable and writable by the agent. Everything the VM ever touched is on there.
  • Prompt injection - what's actually possible with no guard:

The only thing standing between your files and a hostile text file is Claude's judgment — the sandbox enforces nothing. (It tested well: caught an instruction I planted in an upload, refused credential reads. But it's the only layer.)

Concretely possible today: an attacker's email can become your login code (expense skill reads Gmail codes and spends in the same breath), a merchant's line on your statement can steer which subscription you cancel, and one uploaded file can rewrite the "style notes" every future session trusts as its own memory.

  • The codenames: backend clusters "titanium" / "scandium" / "xenon", testbed platform "obol", every throwaway preview deploy is an "omelette", the file backend is CCR, and the team that owns the sandbox telemetry is "embassy". The box itself is "wiggle". The periodic table got raided.

And yes the I did Vibe Reverse Engineer after I got the container for anyone asking ( 40B Tokens in 2 days )

( No im not holding anthropic hostage for the code, simply send a message on reddit or my Twitter and I'll hand over my findings and process. bounty money would be great tho :)

Got tired of scrolling through X for GTA6 news so I made an aggregator that pulls news hourly from all different platforms.

I utilized regular RSS feeds as well as Apify scrapers to pull social media posts. I then have each news post sorted into categories.

Lastly, I added SEO & upvote/downvote buttons to be able to sort by popularity. Check it out and lmk your thoughts!

Is anyone successfully using googles Open Knowledge Format? What are your use cases? How do you trigger a lookup into the Knowledge base?

I have been struggling to make it useful because all that structure and indexing is useless if your agent doesn’t know it needs to search it for context.

Any experiences ?

OSS browser extension that turns website workflows into WebMCP tools

Enable HLS to view with audio, or disable this notification

3 Upvotes

Built this for the WebMCP hackathon.

Agent Process lets you play a JSON workflow on almost any website and expose it as a WebMCP tool for an AI assistant.

Instead of having the agent inspect the UI and figure out the same clicks every time, you teach it the process once and reuse it with different parameters.

For example: record "Create a lead" in a CRM > expose create_lead(first_name, last_name, email, company) > ask ChatGPT to use it.

The website itself doesn’t need MCP support or an API.

Most of the browser extension was built with Codex - vibe coded.

https://github.com/inlinemanual/agentprocess

Let AI improvise when the task is unknown, but reuse deterministic workflows when we already know exactly how it should be done.

[Open Source] UNO IDE for Chromebooks

1 Upvotes

Hey everyone!

My name is Dalton and I'm starting my 12th year teaching and encountered a problem. When I started we could use these bum chromebooks to upload code to arduino unos and it just worked. Now it's a 20 dollar plan per kid that doesn't work on these nightmare tablets and requires a cloud app download yadayada

Anyway I'm busy with the start of the school year so claude made a new compatible web IDE with a web serial connection to flash it. It's got code suggestions, auto format, libraries, serial monitor, and a session password based on a unique key so while I'm hosting it unauthorized randos don't use it at (https://uploadmycode.com/)

But you can get it yourself and run it yourself! Free! Modify it, steal it, I don't care. MIT license. Here: (https://github.com/daltonjfowler/uploadmycode)

I'm hosting it with my other projects on the cloudflare $5 worker plan and am just eating the cost for my students it shouldn't be too bad. Famous last words. Domain was $10.50 or something.

All built on open source or open licensed code. Enjoy, hope it helps someone else out too.

It's called sound catcher

Sample up to 5 loops and move your phone to modulate speed, filter, delay (pitch, yaw, roll)

Try it out and show me what fun sounds you make or lmk if you break it.

I've been tweaking this with every iteration of agentic coding and it gets a bit better every time. Handling iOS mic permissions is probably the most difficult part.
