If you ever worked with complex Stripe integrations, this will save you hours of your life spent combing through multi-storey JSON payloads and tracing sequences of requests that Stripe libraries make. Works with any backend, no changes to application code needed. Webhook support is on the way! submitted by /u/progapandist [link] [留言]

I’ve been improving imagor’s handling of streamed image sources and its libvips image loading path, and updated the benchmark page with current releases. If you work on image delivery, dynamic resizing, or URL-based image processing in web stacks, the updated benchmark summary is here: Benchmark page: https://docs.imagor.net/benchmarks imagor repo: https://github.com/cshum/imagor These results use released versions of imagor, imgproxy, and thumbor. The benchmark page includes summary charts, and the benchmark repo includes committed result summaries for anyone who wants to inspect the setup more closely. Happy to discuss the implementation changes, benchmark setup, or what additional scenarios would be useful to measure. submitted by /u/cshum [link] [留言]

You tweak the parameters and it updates the civilization count instantly, with a 3D Milky Way you can explore, charts, NASA exoplanet data, and bilingual EN/ES. Built with vanilla JS + Three.js, no frameworks. https://mendiak.github.io/drake.equation/ submitted by /u/mendiak_81 [link] [留言]

What I Built I'm thrilled to present Chrono Shift: Time Weaver – a time-bending puzzle platformer that challenges players to manipulate time itself to overcome obstacles and solve environmental puzzles. The Concept Imagine being able to see two versions of the same level simultaneously – the past and the present. In Chrono Shift, you don't just play through a level once; you play through it twice, switching between timelines to create pathways that wouldn't exist in either timeline alone. A bridge that collapsed in the present might be intact in the past. A door that's locked now might be open in the past. By strategically shifting between eras, you create a path forward that exists only through your mastery of time. What Makes It Special Dual-Timeline Mechanics : Switch between past and present with the press of a button, watching as the world transforms around you 10 Unique Levels : Each level introduces new mechanics and challenges, gradually building your time-weaving skills Pixel Art Beauty : Vibrant, hand-crafted pixel art with parallax scrolling backgrounds that bring each era to life Collectible Time Crystals : Find hidden crystals in each level to unlock challenges and achievements Responsive Controls : Smooth platforming with jump, dash, and time-shift abilities that feel tight and satisfying Ambient Soundtrack : Era-reactive music that shifts with your timeline changes, immersing you deeper in the experience Mobile-Friendly : Touch controls mean you can weave time on any device The Journey This game was born from a simple question: what if platformers could teach us about perspective? By forcing players to see the same space from two different temporal viewpoints, Chrono Shift becomes more than just a game – it's a meditation on how our choices in the past shape our present, and how understanding both can unlock possibilities we never saw before. Play it here: https://lovable.dev/projects/bcaa0de3-f14c-4bad-9616-405c896d19bc Video Demo While there's no vi

Modern applications depend on secrets. Every application requires: Database Passwords API Keys SSH Keys TLS Certificates Cloud Credentials OAuth Tokens Service Account Keys The biggest question is: Where should we store them securely? Unfortunately many organizations still store secrets in: Git Repository Docker Image Application Config Files Environment Variables Shared Documents Excel Sheets This creates a massive security risk. This is why Secret Management platforms like HashiCorp Vault became critical in modern cloud-native environments. 🔗 Resources ** Support the Journey on GitHub: If you're following along, consider starring and forking the repo:** https://github.com/17J/30-Days-Cloud-DevSecOps-Journey What is a Secret? A secret is any sensitive piece of information used to authenticate or authorize access. Examples: Database Password AWS Access Key JWT Signing Key API Token TLS Certificate Private Key OAuth Secret If a secret gets exposed: Attacker ↓ Application Access ↓ Database Access ↓ Infrastructure Compromise What is Secrets Management? Secrets Management is the process of: Store Protect Rotate Control Audit sensitive credentials securely. A modern secrets management platform provides: Centralized storage Encryption Access control Secret rotation Audit logs Dynamic credentials Why Secrets Management Matters Imagine this scenario: database : username : admin password : Password123 committed into GitHub. Result: Developer Pushes Code ↓ GitHub Repository ↓ Credential Leak ↓ Database Breach This happens more often than people realize. The Problem with Traditional Secret Storage Many teams use: .env Files Kubernetes Secrets Configuration Files Hardcoded Passwords Problems: Difficult rotation No audit trail Poor access control Risk of accidental exposure Compliance failures What is HashiCorp Vault? HashiCorp Vault is a centralized secrets management platform designed to securely store, access, and manage secrets. Think of Vault as: Central Secret Bank for you

I've been frustrated with SQL learning resources for a while. Most are either: Dry reference docs Toy exercises with no context ("SELECT * FROM employees") Paid platforms with paywalls after level 3 So I built SQLwak — a free, browser-based SQL game where you're hired as a Graduate Analyst at Lion City Bank , a fictional Singapore bank. How it works Instead of abstract exercises, every challenge is a real business request from a colleague: "The Operations team needs all Central region branches for an upcoming audit." "Risk wants customers with credit scores below 600 who have active loans." "Finance needs vessels ranked by cargo revenue — use window functions." You write actual SQL against a realistic 9-table banking database and get immediate feedback. 57 levels across 4 tiers Tier Skills 🟢 Foundational SELECT, WHERE, ORDER BY, LIMIT 🟡 Intermediate JOINs, GROUP BY, HAVING, subqueries 🔴 Advanced CTEs, multi-table aggregations ⚫ Expert Window functions (RANK/DENSE_RANK OVER PARTITION BY), UNION ALL, compound CTEs The database schema Lion City Bank has two divisions: Retail Banking: customers, accounts, transactions, loans, branches, products Maritime Trade Finance (Advanced/Expert levels): vessels, cargo_shipments, trade_finance_facilities — covering voyages between Singapore, Port Klang, Bangkok, Jakarta, and Ho Chi Minh City. The maritime division exists because Singapore is a major trade hub. It makes the Expert levels genuinely interesting — you're ranking vessels by cargo revenue and analyzing trade finance utilisation rates, not just counting rows. Technical details Next.js 15 + TypeScript + Tailwind CSS SQLite via WebAssembly — all query execution is client-side, no backend needed Deployed on Vercel Fully open source: github.com/martinl5/sqlwak No signup. No download. Just SQL. Open the link and start writing queries: sqlwak.vercel.app Would love feedback on difficulty progression, new level ideas, or schema additions.

Been DJing for years and always wanted a way to explore what people are playing in specific cities. Couldn't find anything like that, so I had a crack at it. Click a country, pick a city, and browse DJ sets recorded there. Uses Mixcloud sets and you can browse and play them in browser. https://setatlas.app Happy to hear any feedback or suggestions. submitted by /u/Leather_Catch2136 [link] [留言]

I've been building an image editor that basically lets you edit images, on the fly. Just paste the URL, and you can start editing the image pretty much instantly. Essentially removing the need to download, upload etc. It's very convenient for those who want to quickly make edits. Completely free to use, no login or signup required to use. You can see it here: canvix.me I officially got approved for by google for my official chrome extension, which allows you to right-click any supported image on the internet (png jpg webp etc), Edit image with Canvix option. Right away, you can start editing the image. You can see how it works by screenshot posted on the chrome extension page https://chromewebstore.google.com/detail/edit-image-with-canvix/akjooicgafjjcnpjdfnaajkipciedbco I especially made this for users who constantly need to edit images like me. This in beta testing still, any feedback would be greatly appreciated to improve it. submitted by /u/Filerax_com [link] [留言]

i deleted my earlier post because yeah, it sounded too ai/slop. fair criticism tbh. english is not my first language, so i used ai/translation to explain the project better, but it made the whole thing sound fake and too polished. my bad. so i’ll try to explain it myself this time. so, pardon the wording... i like tracking what i read. i like ratings, reviews, shelves, seeing what other people are reading, making lists, all that stuff. but goodreads always feels weird for me to use. not because the idea is bad, actually the idea is great, but the app/site feels old, messy and not really social enough for something that supposed to be about taste. so i started building my own book tracking app. it’s called Cilt (NOT CLIT!!!!!!!!) for now: https://cilt.app/ the basic idea is kind of “letterboxd for books”, but i know that sentence is overused as hell. what i mean is, i want logging books to feel simple and a bit fun, and after some time your profile should feel like an archive of your reading taste, not just random database list. right now / planned features are: - log the books you read -rate and review them -make shelves like reading, want to read, favorites etc. -create public lists -follow other readers -see what people with similar taste are reading -discover books from reviews/lists, not only generic ratings -track reading goals and stats -search books by title, author, isbn, publisher -have a profile that feels more personal i know there are already apps for this. i’m not saying i invented the wheel or anything. my problem is most alternatives either feels too old, too plain, or they don’t really have the social/taste part that makes letterboxd or even steam fun. also fyi: i didn’t use vibe coding for the whole project. i used it mostly on the frontend side, and when i use it i prefer to say it openly. it’s still very early, so feedback would be really useful. especially from people who still use goodreads even they hate it, or people who tried storygraph/fable

I've been building a static Astro site on Cloudflare Pages over the last few weeks. Sharing the 3 deployment bugs that cost me the most time, in case they save anyone else the same loop. Setup Astro 5 + Cloudflare Pages + Tailwind 4. Content lives in a few JSON files; each page is a dynamic route mapped over the data. Free-tier hosting, no backend. Standard static-first stack. Bug 1: Trailing-slash 307 chain I started with trailingSlash: 'never' in Astro config. Build output went to dist/foo/index.html . Result: Astro emitted canonical tags as /foo (no slash), but Cloudflare Pages served /foo/ (auto-adding the slash via 307). Google Search Console flagged pages as "Redirect error" because the canonical URL pointed at a redirect chain instead of a real 200. I first tried build.format: 'file' to get flat dist/foo.html output, hoping that would bypass the trailing slash. That made it worse — Cloudflare still 307-stripped, but now to a non-existent .html file → 404. Fix: stop fighting the platform. ​ js // astro.config.mjs export default defineConfig({ trailingSlash: 'always', // ... }); ​ trailingSlash: 'always' plus default directory build aligns the canonical URL with what Pages actually serves. The redirect errors resolved on next re-crawl. Bug 2: _redirects rejected at deploy I tried to do a www → apex 301 in public/_redirects : https://www.example.com/* https://example.com/:splat 301! Cloudflare rejected the deploy with three validation errors: ​ Line 13: Only relative URLs are allowed. Line 22: Duplicate rule for path /foo. Line 23: Duplicate rule for path /bar. ​ Pages tightened _redirects validation — absolute-URL sources aren't accepted anymore. The duplicate errors were because Astro's own redirects config in astro.config.mjs generates HTML meta-refresh files that Pages parses as implicit redirect rules — conflicting with my explicit ones. Fix: delete _redirects entirely. Use a Cloudflare Redirect Rule from the dashboard for cross-host 301s (Wildcard pattern,

I Benchmarked Lynkr Against LiteLLM on the Same Backends. Lynkr Was Cheaper for Tool-Heavy Workloads Founder disclosure: I built Lynkr, so take this as a technical benchmark write-up, not a neutral industry report. The numbers below come from the same backend providers on both gateways. If you're routing AI coding traffic through a gateway, just switching providers is not enough. The real savings come from reducing the tokens that ever reach the model in the first place. I ran Lynkr and LiteLLM against the same backends — Ollama locally, Moonshot, and Azure OpenAI — across 9 scenarios. On the scenarios that actually look like agentic coding work, Lynkr was cheaper because it does three things before forwarding the request upstream: smart tool selection, TOON compression, and semantic caching. The short version Lynkr was measurably better on the cost-sensitive parts of the workload: Smart tool selection: 53% fewer input tokens, 52% lower cost TOON JSON compression: 87.6% fewer billed tokens on a large tool result, 50% lower cost Semantic cache: 171ms cache-hit response vs 3,282ms on the repeat query path Tier routing: escalated hard prompts to stronger models instead of blindly sending everything to the cheapest route Area Lynkr result Why it mattered Tool selection 53% fewer tokens Removes irrelevant tool schemas TOON compression 87.6% fewer tokens Shrinks large JSON tool outputs Semantic cache 171ms cache hit Avoids repeat model calls Tier routing Escalates hard prompts Doesn’t over-optimize for cheapest path This matters if you're running Claude Code, Codex, Cursor, or similar agent workflows where tools, file reads, grep output, and repeated context dominate your token bill. Setup Same benchmark inputs, same providers, same request shape. Machine: macOS on Apple Silicon Lynkr: v9.3.2 on Node 20 LiteLLM: v1.87.1 on Python 3.12 Backends used: Ollama local, Moonshot, Azure OpenAI Scenarios: 9 total across simple prompts, tools, history, cache, and routing Each scena

Hi! I just created a project where people can interact with someone who has experienced the effects of the war in Ukraine. The project consisted of interviewing different families that suffered during the war to understand the situation on an emotional and day-to-day level. Then, using this information, I created an AI agent with the sole purpose of discussing what it is like to live through a conflict. The goal is to reach people who may have forgotten about the conflict and make them more sensitive about the ongoing war. You can find the access to the project here: War Owned Project Please, can you share your thoughts? Thank you and warm regards from Barcelona! submitted by /u/Budget-Cheesecake-19 [link] [留言]

noticed the AMC theatres site has had queue times of over an hour today… just to get onto the homepage. That’s a bit strange right? AMC has ~650 locations in the US. Assuming ~10 screens per location, ~5 showings per screen per day, and ~300 seats per auditorium (probably a generous estimate), that’s roughly 10 million available seats per day. Even if site traffic is 5x higher than actual ticket sales, we’re still talking about something in the ballpark of 50 million daily visitors. That’s obviously not nothing, but it also doesn’t seem like an absurd amount of traffic for a company this large. I’m curious what the technical/business rationale could be? submitted by /u/u16scharpf [link] [留言]

I am a web developer who specializes in dashboard-like web applications. Due to recent price hikes for GitHub Copilot, I have been considering running a local model to help out with debugging, multi-file edits, learning about the codebase, and small-medium tasks. I intend to continue using GitHub Copilot or Claude Code for more advanced tasks, but I want to minimize token costs. I cannot test a local model myself right now because I lack the hardware to do so, which is why I am asking here. If I decided on using a local model, I would likely need to upgrade my graphics card from a 3080 to a 3090. Has anyone here tried running a local AI model? Which one are you using? How well does it work compared to Claude Sonnet 4.5 or other AI models? I would appreciate any advice or feedback. submitted by /u/Various-Complex-1582 [link] [留言]
