A honeypot is the cleanest way to drain a trading bot on Solana: the token lets you buy , but there is no way to sell . Your agent spends real USDC, receives tokens, and then discovers the exit is welded shut. The position is worth zero and there is nothing to do about it. Honeypots don't show up on a price chart — the chart looks great, because everyone can buy and nobody can sell. You only find out at exit. So the check has to happen before the buy. What makes a Solana token a honeypot No live sell route — there is simply no route back to USDC/SOL on any DEX. The most common case. Transfer restrictions — Token-2022 extensions like transferHook or pausable let the creator block transfers (and therefore sells). Freeze authority — the issuer can freeze your account so the tokens can't move. Detect it in one call RugCheck AI is a remote MCP server. Point your agent at the endpoint and ask before any buy: simulate_sell("<mint>") -> { sellable: true|false, verdict: "..." } A token with no live sell route comes back sellable:false — that's the honeypot, even when nothing on-chain formally blocks the sell yet. For the full picture in one shot: scan_token("<mint>") -> { verdict: SAFE|CAUTION|DANGER, safety_score, sellable, risks: [...] } Or simulate the whole round-trip at your real size: simulate_trade("<mint>", 100) -> { buyable, sellable, exit_usd, round_trip_loss_pct } A honeypot shows buyable:true, sellable:false. A healthy token shows a small round-trip loss (slippage) and sellable:true. A real one I scanned a fresh pump token on 2026-06-17 (re-run to verify): scan_token returned DANGER, score 20 — no live sell route, 100% of supply held by a single wallet, $0 liquidity. An agent that bought it could never get out. That verdict is available before the buy, even though the token is too new to be indexed anywhere else. Wire it into your agent It's a standard Streamable HTTP MCP server. In Cline / Claude Dev, add an mcpServers entry named rugcheck-ai pointing at the end

Building a high-performance Polymarket trading bot requires mastering its unique hybrid architecture:...

HiveTalk.space is a privacy focused chat app. HiveTalk.space should not be confused with hivetalk.org. While both platforms focus on communication, they are separate projects with different goals and feature sets. HiveTalk is closed source and cloud hosted, making it easy to start chatting without setting up your own server. Despite not being self-hosted, privacy remains a core focus. Private conversations are designed with privacy in mind, allowing users to communicate without unnecessary tracking or intrusive data collection. Every account includes generous free limits. Users can upload files and videos up to 1 GB each, send unlimited messages , and sign in using supported social login providers or a traditional account. Creating communities is simple, with the ability to make your own chat rooms for friends, gaming groups, project teams, schools, or fanbases in just a few clicks. HiveTalk also aims to provide a modern messaging experience with features such as polls, rich text formatting, media sharing, and room management tools, while keeping the interface simple and easy to use. Whether you want a private conversation, a small group chat, or a larger community, HiveTalk is designed to scale without placing artificial limits on everyday usage. Unlike many messaging platforms that reserve key features for paid subscriptions, HiveTalk offers its core functionality for free. The goal is to make private, feature-rich communication accessible without requiring users to pay just to unlock basic messaging features. As the platform continues to develop, new features and improvements are regularly added, with a focus on privacy, usability, and giving communities more control over how they communicate.

AI agents get better the more they run. Every conversation turn, every task completed, every prompt refined adds to a growing body of context that shapes the next output. The compounding effect is real: an agent with 100 turns of memory and a versioned prompt history behaves meaningfully differently from one starting cold. This post walks through using a structured, versioned, API-accessible store as the memory layer for AI agents, with TypeScript examples. Agent messages, system prompts, findings, and instructions are all stored as structured, versioned, API-accessible Objects. Each new turn adds to the record. Each prompt edit is tracked. What Agent Memory Actually Needs The compounding loop only works if the memory layer has the right properties. Most agent frameworks handle working memory well. The gap is episodic and semantic memory: what the agent learned, did, and produced across sessions. Researchers at Elastic recently published a breakdown of agent memory tiers : working memory (in-context), episodic memory (past interactions), semantic memory (knowledge), and procedural memory (learned behaviors). Good persistent agent memory needs four properties: Structured : queryable by type, status, date, or custom field, not just full-text search Versioned : you need to know what the agent wrote at each point in time, not just the latest state API-accessible : any model, any framework, any language should be able to read and write it Human-reviewable : agents make mistakes; a human needs to inspect and correct outputs without touching a database Objects as Agent Outputs When an agent produces output, storing it as a structured Object gives you a queryable record with typed fields, a draft/published workflow so a human can review before promoting to production, a full audit trail of every change, REST API access from any runtime, and a dashboard UI where non-technical team members can inspect, edit, or approve agent outputs. Here's a simple research agent that stores

I was building a feature that needed to say something useful about a stock — not just print its P/E, but actually read the situation: is this cheap or expensive, what's the bull case, is the insider buying real or routine. I went looking for an API. Every finance API I found sold me raw data . Alpha Vantage, Twelve Data, Yahoo Finance, FMP — they'll hand you fundamentals, prices, filings, all of it. Great. Now I get to write the part that turns 40 metrics into "this looks expensive but the moat is widening." That's the part that's actually hard, and the part I didn't want to own forever. So I'd be wiring three data providers, normalizing their conflicting field names, writing and tuning the LLM prompts, handling the rate limits and the caching, and then maintaining all of it as the upstreams change. For a feature, not a product. What I wanted instead A single endpoint. Ticker in, analysis out — already synthesized, already structured. That's what I ended up building for myself and then put on RapidAPI: Agent Toolbelt — AI Stock Research API . It pulls live fundamentals from Polygon, Finnhub, and Financial Modeling Prep, then returns a Motley-Fool-style read as typed JSON. The numbers are in there too, but the point is the verdict and the reasoning. Here's a real stock-thesis response: { "verdict" : "bullish" , "oneLiner" : "Nvidia owns the essential infrastructure for the AI revolution with a defensible software moat." , "keyStrengths" : [ "~80%+ data center GPU market share" , "CUDA moat creates switching costs" , "42 buy / 5 hold / 1 sell analyst consensus" ], "keyRisks" : [ "36.9x P/E leaves no margin for error" , "Competition from AMD and custom silicon" ], "insiderRead" : "Two executives bought ~47k shares each — meaningful open-market purchases, not routine grants." , "dataSnapshot" : { "currentPrice" : 180.4 , "peRatio" : 36.9 , "marketCapBillions" : 4452.2 } } That's one HTTP call. No data-provider accounts, no prompt engineering, no normalization layer. The

I launched Firefox this morning to find some new blocks on my home page.

Most SaaS ideas don’t fail because of bad ideas. They fail because the execution gets stuck in an endless setup loop. You start with energy, then slowly get buried in: auth systems, billing, dashboards, SEO, analytics, and infrastructure decisions. By the time the “real product” should begin, momentum is already gone. Here are 7 practical alternatives to building SaaS in a way that never gets finished. 1. Nexora (start with a working SaaS foundation) Instead of rebuilding everything, Nexora gives you a production-ready base so you can focus on actual features. Includes: Authentication system Stripe billing User dashboards SEO pages Blog + docs structure Clean Next.js architecture 🔗 https://nexora.collabtower.com/ 👉 Best for founders who want to ship instead of setup. 2. Build-from-scratch Next.js projects The most common approach. You get: Full control Flexible architecture But you also get: Weeks of setup Repeated boilerplate work High chance of burnout before launch 3. SaaS boilerplates (minimal versions) Lightweight starter kits with: Auth Basic UI Simple Stripe setup But usually missing: Real dashboards SEO systems Production-level structure 4. Supabase-first builds Backend-focused setups. You get: Database Auth APIs But still need to build: Billing UI system Marketing pages SaaS structure 5. Low-code SaaS tools Fast visual builders. Pros: Quick UI creation No heavy coding Cons: Limited flexibility Hard to scale complex SaaS logic Platform dependency 6. AI-generated starter apps AI tools can scaffold SaaS apps instantly. Pros: Fast starting point Cons: Inconsistent structure Requires cleanup Not production-ready out of the box 7. Tutorial-based SaaS builds Many developers still learn SaaS by following tutorials step-by-step. Pros: Educational Cons: Slow Fragmented Hard to turn into real production apps Final takeaway Most SaaS workflows fail before launch because they repeat the same mistake: They start from zero every single time. That creates unnecessary setup

Quick update to anyone interested in upcoming changes to the PAGI project (spiritual successor to Plack/PSGI). 1) Distribution split up: when we released PAGI, we initially released everything as one distribution. PAGI ( https://metacpan.org/pod/PAGI ) currently has a) the PAGI specification; b) the reference server and c) a bunch of ease of use tools, similar to the role that the Plack distribution played for PSGI. Putting everything into one place was just to make my life easier as in the early bunch of releases there was a lot of fixes and updates, most of which cut across all three parts of PAGI. Also I wanted to make it easy for people getting into PAGI to be able to explore the ecosystem. However now that code seems to be settling down having these in independent repos and releases makes more sense. Going forward the PAGI repo will only update if the spec itself changes; PAGI::Server and PAGI::Tools (where all the utilities and helpers now go) likewise. I think this will start to bring some stability to the ecosystem, especially now that PAGI::Server is functionally complete based on the goal chart I had for it initially. So I will only update it to fix bugs and security issues. PAGI::Tools will probably continue to see evolution over the summer as I start to nail down more common use cases and identify patterns worth encapsulating. 2) Specification clarifications and updates: The PAGI specification itself will move to v0.3 in the next release and it contains mostly clarifications and fixes. Biggest change will be a more detailed mechanism for controlling streaming output, especially around handling back pressure as well as new callbacks to notice when the output buffer is getting full and when it clears. Hopefully these changes will make it easier and more reliable to do streaming in PAGI. PAGI::Server has been updated to match, and the response helper in PAGI::Tools has some updates around that as well. Currently all this sits on Github: https://github.com/j

Disclosure up front: I'm affiliated with diagram.now — I'm connected to the product. I'm posting this to get developer feedback on diagram import/export interoperability, not to pitch an install. Most teams I've worked with don't have one source of truth for their diagrams. They have: a few Mermaid blocks living in READMEs and Markdown docs, an old Visio ( .vsdx ) or Lucidchart file someone made two reorgs ago, a SQL schema that is secretly the "real" ERD, and a pile of screenshots pasted into docs and tickets. The diagram is rarely the hard part. The hard part is that the same diagram lives in five formats and none of them stay in sync with the docs they're supposed to explain. I've been working on diagram.now , a browser-based editor for technical diagrams — flowcharts, UML, ERD, BPMN, cloud/network architecture, mind maps, wireframes. It's a free browser editor with no signup to start. There's an optional Confluence app for teams that want diagrams editable inside Confluence pages, but that's intentionally not what I want to talk about here. I want feedback on the editor itself, and specifically on the interoperability story. What it does today Import/insert from Mermaid and SQL — paste a Mermaid graph or a CREATE TABLE block to start an editable diagram instead of a static render. Import Lucidchart and Visio .vsdx files — this is migration-oriented, and honestly the part I most want real-world files to stress-test. Export to PNG, SVG, PDF, or a URL. Templates/shapes for the diagram categories above. I'm deliberately keeping the Confluence side secondary. The thing I actually want to learn is whether the browser editor plus import/export is useful on its own. Where I'd love feedback Imports: Which format matters most to you — Mermaid, SQL→ERD, .vsdx , Lucidchart, or something else (PlantUML, draw.io XML, Graphviz)? If you've ever tried to migrate diagrams between tools, where did it break? URL export: Is a shareable diagram URL genuinely useful in your workflow (

A few months ago I started building small tools as single HTML files - no npm, no React, no backend. Just one file that opens in a browser and works offline. I built 4 real products this way: DarkenAmber IT Tools - 17+ developer tools in 194KB ZeroOffice - PDF, image, AI tools in one file PrivacyKit - Photo privacy tools, no upload required ElectroKit - Electrical calculator + cost estimates for CIS market Every single one: one .html file. Works offline. Opens instantly. No server. The problem with AI coding assistants Every time I asked Claude or Copilot to build something simple, I got: A React project with src/ folder package.json with 12 dependencies webpack config TypeScript setup ...before writing a single line of actual logic. I kept manually correcting it. "No, one file. No npm. Vanilla JS." Then I realized - I should just teach it once and reuse that knowledge. What is a Claude Skill? A skill is a Markdown file with YAML frontmatter that changes how Claude thinks for a specific context. It is not a prompt. It is not a system message. It is a reusable set of rules that shapes how Claude reasons, what it prioritizes, and what it avoids. yaml--- name: single-file-app description: "Build complete web tools as a single HTML file - vanilla JS, inline CSS, localStorage, offline-first." tags: html vanilla-js offline version: 1.2 --- The two skills I built single-file-app Teaches Claude to build complete web tools in one HTML file. What changes: No React, no npm, no build tools unless truly justified Vanilla JS first, always localStorage for data persistence Dark/light theme with system preference detection Accessibility built in (labels, aria, keyboard nav) XSS prevention for user input Export/import for user data Anti-patterns it prevents: ❌ "Let me set up a React project" ❌ Creating src/ folder for a simple tool ❌ Suggesting npm install for a calculator ✅ "Here is your complete HTML file" ship-it Teaches Claude to bias toward shipping over planning for early-stag

Ky 2.0 is an open-source JavaScript HTTP client built on the Fetch API, featuring significant updates such as consolidated hook handling, enhanced timeout management, and improved URL processing. The release includes response validation through schema validation libraries and addresses migration from earlier versions. It aims to provide a lightweight alternative to axios. By Daniel Curtis

The problem I kept running into I'm a chronic tab hoarder. At any given time I've got 40–80 tabs open across two windows. Chrome's built-in Memory Saver is aggressive in the wrong ways — it hibernates tabs I'm actively referencing. And the built-in task manager is a two-step detour that still doesn't tell me which tabs I should actually close. So I built Tab Memory Manager. What it does Per-tab memory estimates — A live MB count next to every open tab. Sorted by memory usage by default. There's a live total on the toolbar icon so you always know what Chrome is consuming right now. Smart suggestions — The extension flags your biggest, stalest tabs: ones that are idle the longest and consuming the most. It never suggests your active tab, pinned tabs, tabs playing audio, or domains you've whitelisted. Hibernate, don't close — This was the core design decision. Hibernating frees the memory but keeps the tab alive in your strip — it reloads when you click it. Much safer than closing, especially mid-research. Bulk cleanup — Select multiple tabs or hit Apply on the suggestions panel. See the total memory you'll reclaim before you commit. Undo list — Closed something by mistake? There's a "Recently cleaned" panel. One click to restore. Tab grouping — Groups all your open tabs by domain into color-coded Chrome tab groups, instantly. The interesting technical bit: memory estimates Chrome's stable extension API doesn't expose exact per-tab memory. The chrome.processes API that does exists only on Dev and Canary builds — not the Chrome that 99% of people use. So Tab Memory Manager uses calibrated estimates based on tab state, domain patterns, and known Chrome process overhead. These are clearly labeled "est." in the UI. If you're on Dev or Canary, you can switch on real per-tab memory in settings. The warning Chrome shows about "processes requires dev channel" is a Chrome-generated note about that optional API — the extension works completely normally without it. It's not a bug

One of the challenges I faced while building my LaTeX Writer project was implementing version control and project forking in a storage-efficient way. A typical LaTeX project contains multiple files. Even a simple project usually has a "main.tex" file, bibliography files, images, style files, and other supporting documents. If I stored a complete copy of every file for every version or fork, storage requirements would grow rapidly. Imagine a project with four files and ten versions. Storing the entire project for every version would mean storing the same files repeatedly, even when only one line changed. Forking would create an even bigger problem because every fork would require another complete copy of the project. Instead of accepting this inefficiency, I started researching how large platforms solve the same problem. GitHub was the obvious inspiration. Learning from GitHub GitHub does not store a complete copy of a repository every time a change is made. Instead, it stores content separately and uses references to connect files, commits, and repositories. This idea became the foundation for my own implementation. Project Structure Whenever a new project is created, a default file called "main.tex" is generated automatically. The project itself does not directly contain file contents. Instead, it stores metadata such as: Project ID Owner ID Root Folder ID File References Each file also has its own metadata record containing: File ID File Name Blob ID Project ID Owner ID Folder ID The actual content is not stored inside the file metadata. Instead, the content lives inside a separate entity called a Blob. Loading a Project When the editor loads a project, it reconstructs the directory structure using metadata. The process works like this: Retrieve the project's Root Folder ID. Find all folders belonging to that folder hierarchy. Find all files belonging to each folder. Build the directory tree for the frontend. Because files and folders are stored independently, the

Have you ever tried to track your calories by manually searching for "half-eaten avocado toast" in a database? It’s a nightmare. While basic AI Computer Vision can identify an "apple," traditional models often fail at the granular level—distinguishing between 100g and 250g of pasta or identifying hidden toppings in a complex salad. In this tutorial, we are building a high-precision food nutrition AI engine. By combining the Segment Anything Model (SAM) for pixel-perfect object isolation and GPT-4o Vision for multi-modal reasoning and volume estimation, we can transform a simple smartphone photo into a detailed nutritional report. If you’re looking to dive deeper into production-grade AI patterns, I highly recommend checking out the advanced engineering guides at WellAlly Blog , which served as a major inspiration for this architecture. 🏗️ The Architecture: A Hybrid Vision Pipeline To achieve high accuracy, we don't just throw an image at an LLM. We use a "Segment-then-Analyze" pipeline. This ensures the LLM focuses on specific regions of interest (ROIs) rather than getting distracted by the background. graph TD A[User Uploads Food Image] --> B[Pre-processing with OpenCV] B --> C[SAM: Segment Anything Model] C --> D{Multi-Object Masking} D -->|Mask 1: Protein| E[GPT-4o Vision Reasoning] D -->|Mask 2: Carbs| E D -->|Mask 3: Veggies| E E --> F[Nutrient Mapping & Volume Estimation] F --> G[FastAPI Response: JSON Schema] G --> H[Final Dashboard] 🛠️ Prerequisites Before we start, ensure you have your environment ready: Python 3.10+ GPT-4o API Key (OpenAI) SAM Weights ( sam_vit_h_4b8939.pth ) Tech Stack : FastAPI , OpenCV , PyTorch , segment-anything 🚀 Step-by-Step Implementation 1.

(Without Fighting upload_max_filesize ) You deploy your app. A user picks a 400 MB video. They hit upload. The progress bar freezes. Then — nothing. You check the logs. POST Content-Length exceeded post_max_size . Again. We've all been there. The fix is usually "raise PHP limits" or "use S3." Both work — until you're on shared hosting, a legacy VPS, or a client who won't touch php.ini . That's the problem Pinion solves. What is Pinion? Pinion is an open-source resumable chunked upload protocol for PHP. Instead of one giant multipart/form-data request, the browser sends the file in small parts (default: 5 MB). The server stores each part, then assembles the final file on disk. Three steps. That's the whole contract: init → upload parts → complete Package Registry Role pinoox/pinion Packagist PHP server engine @pinooxhq/pinion-client npm Browser client Protocol id: pinion · version: 2 Why not just use S3? Object storage is great. But sometimes you need files on your server : A CMS media library on local disk A Laravel app without cloud budget Shared hosting with no S3 SDK An admin panel behind a simple PHP API Pinion isn't a CDN or a storage service. It's a protocol — a stable HTTP contract that works in plain PHP, Laravel, or Pinoox.

O Event Loop é o mecanismo responsável por decidir quando callbacks e continuidades de operações assíncronas devem ser executados. Ele não executa operações de I/O diretamente, mas organiza a ordem em que elas retornam para o JavaScript. Essa arquitetura permite que o Node.js mantenha uma única thread de execução para JavaScript, enquanto delega operações de rede, disco e sistema operacional para componentes especializados do runtime e do próprio sistema operacional. Início Quando iniciamos um processo Node.js, o runtime carrega o arquivo de entrada da aplicação e executa todo o código síncrono disponível na Call Stack. Somente após essa etapa o Event Loop passa a assumir o controle do fluxo da aplicação, verificando continuamente quais callbacks estão prontos para execução. │ timers │ └─────────────┬─────────────┘ │ v ┌───────────────────────────┐ ┌─>│ pending callbacks │ │ └─────────────┬─────────────┘ │ ┌─────────────┴─────────────┐ │ │ idle, prepare │ │ └─────────────┬─────────────┘ ┌───────────────┐ │ ┌─────────────┴─────────────┐ │ incoming: │ │ │ poll │<─────┤ connections, │ │ └─────────────┬─────────────┘ │ data, etc. │ │ ┌─────────────┴─────────────┐ └───────────────┘ │ │ check │ │ └─────────────┬─────────────┘ │ ┌─────────────┴─────────────┐ │ │ close callbacks │ │ └─────────────┬─────────────┘ │ ┌─────────────┴─────────────┐ └──┤ timers │ └───────────────────────────┘ Trecho retirado da documentação principal. Sobre o Event Loop Durante muito tempo tratei o Event Loop como um dos conceitos mais complexos do Node.js. Depois de estudar a documentação oficial com mais calma, percebi que a dificuldade não está no Event Loop em si, mas na quantidade de conceitos diferentes que normalmente são apresentados ao mesmo tempo: libuv, Call Stack, Promises, Microtasks, Sistema Operacional e I/O. Quando isolamos o papel do Event Loop, ele se torna surpreendentemente simples. Definindo os passos e apresentando o iceberg 🧊 O Event Loop não executa trabalho. Ele agenda tr

Most dashboard icon problems do not come from bad icons. They come from good icons used with the wrong meaning. You search for users , pick a clean SVG icon, place it in the sidebar, and move on. Then later you need another icon for: Customers Team members Account owners Permissions Audiences Invited users Admins Suddenly, the same “user” metaphor has to carry too many meanings. That is where SaaS dashboards often start to feel noisy. Not because the icons are ugly. Not because the SVGs are technically wrong. Not because the design system is broken. Because the icon choices were made by keyword instead of meaning. Keyword search is only the first step Most developers choose icons like this: Need an icon for billing? Search billing . Need an icon for users? Search users . Need an icon for analytics? Search chart . Need an icon for settings? Search settings . That works for finding candidates. But it does not solve the real UI problem. A keyword tells you what the icon is related to. It does not tell you what the icon means in your product. For example, search for settings . You might find: A gear Sliders A wrench Control knobs A preferences panel A tune icon They all match the keyword. But they do not say the same thing. A gear usually means global settings. Sliders suggest adjustable preferences or filters. A wrench feels technical or maintenance-oriented. Control knobs suggest fine tuning. A panel icon may suggest a configuration screen. The same keyword can point to different mental models. And in a dashboard, mental models matter more than decorative accuracy. SaaS dashboards are meaning-dense interfaces A marketing website can sometimes get away with decorative icons. A SaaS dashboard cannot. Dashboards are dense. They contain navigation, actions, status indicators, tables, filters, empty states, permissions, billing screens, integrations, reports, and settings. Users do not look at each icon in isolation. They scan. They compare. They move quickly. They expect
