| Still working on my tool for creating custom Tailwind-style

|
| https://www.inclusivecolors.com/
|
| There's millions of tools that try to autogenerate colors for you
| using algorithms and AI, but they usually ignore WCAG accessible
| contrast requirements, don't let you customise the tints/shades,
| don't let you create a full palette of colors, and the colors
| often don't look right on actual designs.
|
| This tool is meant to make customising tints/shades intuitive and
| quick enough in a few clicks via a hue/saturation/lightness curve
| editing interface that you won't want to rely on autogeneration.
| There's also a live mockup showing how your palette looks on a UI
| design that checks pairings pass contrast requirements, to guide
| you as you tweak your colors and to teach you the WCAG rules.
|
| You can then export your palette to regular CSS variables,
| Tailwind, Figma or Adobe for use in your designs.
|
| Really open to any feedback on features that would be useful! I
| think the only way I can make it simpler to use is to make it
| more opinionated about how your palette should be designed so
| interested in any thoughts about that too.

|
| The general philosophy is to not assume any native controls,

| the default keyboard controller.
|
| The underlying API is defining operations from two

|
| The one limitation is that we have to convert a bunch of

|
| - References -- Named sets of components defined via Tag

|
| - Statements -- Architectural intent constraints that can be

|
| RespCode puts you back in control with 3 orchestration modes:
|
| Compete Mode -- Send your prompt to Claude, GPT-4o, DeepSeek, and
| Gemini simultaneously. See all 4 solutions side-by-side, compare
| approaches, and pick the winner. You're the judge.
|
| Collaborate Mode -- Chain models together in a refinement
| pipeline. DeepSeek drafts - Claude refines - GPT-4o polishes.
| Each model improves on the last, with full visibility into every
| stage.
|
| Consensus Mode -- All models generate independently, then Claude
| synthesizes the best parts into a merged solution. Democratic
| code generation.
|
| But here's what makes it actually useful: Every piece of
| generated code runs instantly in real sandboxes -- not simulated,
| not mocked. We support x86_64, ARM64, RISC-V, and ARM32
| architectures. You see compilation output, runtime results, and
| exit codes in seconds.
|
| Why "Human in the Loop" matters: AI models are powerful but
| imperfect. RespCode doesn't hide this -- it exposes it. When you
| see GPT-4o produce clean code while Gemini's version has a bug,
| you learn which models excel at what. When Collaborate mode shows
| how Claude fixed DeepSeek's edge case, you understand the
| refinement process.
|
| You're not just accepting AI output. You're supervising,

| So i split it into two groups of stuff im working on:
|
| Main Projects: 1. cyberbrain (
| https://github.com/voodooEntity/cyberbrain ) It is a golang based
| architecture to write event/data driven applications. It is based
| on an in-memory directed graph storage ( i also wrote
| https://github.com/voodooEntity/gits). The point of the system is
| that instead of writing code where A calls B calls C calls D ....
| you define single "actions". Each action has a
| requirement/dependency in form of a data structure. If a
| structure is mapped to the graph storage, it will automatically
| create singular payloads for such action executions. The
| architecture is multithreaded by default, meaning all "jobs" will
| be automatically parallel processed without the developer having
| to care about concurrency. Also, since every "thread/worker" also
| does "scheduling" new "jobs", the system scales very well with
| alot of worker.
|
| Why? Well it mainly developed this architecture for the next
| project im listing.
|
| 2. Ishikawa : an automated pentesting/recon tool Ishikawa does
| not try to reinvent well established pentesting/recon tools,
| instead it utilizes and orchestrates them. The tool consists of
| actions that either do very simple things like
| resolveIPFromDomain , or actions which utilize existing tools
| like nmap, wfuzz, etc.. - collects the info in the central graph
| and at the end you get a full mapping of your target. Compared to
| existing solutions it does alot less "useless scans" and just
| fires actions which make sense based of the already gathered data
| (we found a https port, we use sslscan to check the cert...).
|
| 3. Gits (as mentioned above) a graph in memory threadsafe
| storage. While i don't plan to many changes on it, it has been
| developed for cyberbrain so if i need any additions ill do them,
| also planing to reenable async persistence.
|
| Regarding ishikawa: while im still working on this project, it
| may be that i will shut it down. I had a rather expensive meeting
| with a lawyer that basically told me that open sourcing it while
| beeing a citizen of germany would just open up potentially ALOT
| of trouble. Right know im not sure what the future will bring - i
| basically spend 10 years developing it starting with gits, than
| cyberbrain to finally build the tool i was dreaming of. Just to
| hide it on my disk.
|
| Sideprojects:
|
| 1. go-tachicrypt ( https://github.com/voodooEntity/go-tachicrypt
| ) It started as a fun project/experiment - a very simple CLI tool
| which allows to encrypt file(s) / directory(ies) into multiple
| encrypted files so you can split them over multiple storages or
| send them via multiple channels. Im planing on hardening it a bit
| more and giving basic support.
|
| 2. ghost_trap ( https://github.com/voodooEntity/ghost_trap ) A
| very small project i recently put out, nothing to serious but
| kinda funny and maybe usefull to one or another. It provides - An
| github action that will inject polymorphic prompt injections to
| the bottom of your README.md so LLM scrapers may be fend off - An
| javascript that will inject polymorphic prompt injections into
| your html so more sophisticated crawlers like google etc which
| emulate javascript also may be fend off

|
| So over the last few days I've been tinkering with a project I

|
| How it works (high level):
|
| * The iOS app discovers nearby Macs using MultipeerConnectivity
|
| * Keyboard input and touch gestures are streamed directly to
| macOS
|
| * The macOS app injects events at the system level (requires
| Accessibility permissions)
|
| * No shared Wi-Fi network required; devices connect peer-to-peer
|
| It's very early, but already supports basic typing and cursor
| control--especially useful in cramped spaces like planes.

| Here's the TestFlight link for the brave. You'll need to install

|

| party roundtrips (summaries, labelling, embedding etc..) which
| breaks the "instant" system. We're experimenting with ways to
| design those flows so the system still feels fast. Currently we
| only have one "loading" request in the entire system.
|
| Having all data available on the client has also lead to some
| neat benefits. No need to compose or build your typical GET
| endpoints in the API. You just query the client DB directly!

| I'm working on https://aero.zip, a file transfer service designed

| or browser crashes.
|
| The goal was to build something as fast as a native app but with
| the convenience of a web link. Some of the technical bits:
|
| * Instant Streaming: Recipients can start downloading a file the
| moment the first chunk leaves the sender's computer. No waiting
| for the full upload to finish.
|
| * Bespoke Chunking Protocol: To handle "unlimited" file counts
| (tested into the millions), we group small files into larger
| chunks and split massive files down, so many small files and a
| few large files can get transferred at similar speeds.
|
| * Auto-Resume: Both uploads and downloads automatically resume
| from the exact byte where they left off, even if you switch
| networks or close/reopen your laptop.
|
| * E2EE via Web Crypto API: Everything is AES-GCM-256 encrypted.
| The secret key stays in the URL fragment (after the #), so it
| never gets sent to our servers.
|
| * Zero-Knowledge Auth: We use the OPAQUE protocol for logins,
| meaning we can authenticate users and store their encrypted Data
| Encryption Keys (DEKs) without ever seeing their password or
| having the ability to decrypt their files.
|
| * Passkey + PRF: We support the WebAuthn PRF extension. If your
| passkey supports it (like iCloud Keychain or YubiKeys), you can
| decrypt your account's metadata without the password.
|
| * On-the-fly Zipping: When a recipient selects multiple files,
| the browser decrypts and zips them locally in real-time as they
| stream from our server.
|
| * Performance: Optimized to saturate gigabit connections (up to
| 250 MB/s) by maintaining persistent streams and minimizing
| protocol overhead.
|
| Everything is hosted in Germany (EU) for GDPR compliance. I'd
| love to hear any feedback on the streaming architecture or the
| OPAQUE implementation!
