I've figured out how to make a version of AWS lamda that can bootup in less than 20ms (user code transfer + start, excluding user code bootup time) have any of you had issues with cold starts? Would this kind of concept be useful to you?

I've been playing chess for a few years with my ELO stuck around 1600 on Lichess. I wanted an app that combined puzzle training, interactive lessons, game analysis, and AI coaching in one place. But all the apps I used over the years either felt overwhelming, had UX that wasn't up to my expectations for a modern app or were lacking some fundamental features that I really wanted. So, I built LearnChess.ai.

The technical angle I'm most excited about: it's built local-first using LiveStore (event-sourced, SQLite on-device), which means zero loading delays for user data and full offline support. Sync to the cloud happens in the background for cross-device usage. The stack is TanStack Start (web), Expo (mobile), and it runs entirely on Cloudflare.

Features in the current beta: - Puzzle trainer with community submissions - Guided lessons for openings and endgames - Game import and analysis from Lichess & Chess.com - Opening explorer based on your own game history - Stockfish running on a dedicated Hetzner server (faster than in-browser WASM) - AI coaching integrated directly in the analysis board - Coordinate training, beginner track, leaderboards, ...

Available on web, iOS (TestFlight), and Android (nearly ready).

Would love your feedback — both on the product and the architecture choices!

The article explores the challenges and decision-making process faced by pilots when their flights encounter missile activity, including options to divert, turn back, or fly around the conflict zone to ensure the safety of passengers and crew.

I built zmod because running jscodeshift on a large enterprise monorepo was taking 4-5+ minutes.

It's 100% API compatible with jscodeshift — just swap the import — but powered by Rust + oxc under the hood.

Benchmarked at 8x faster on average, up to 11.7x on small files. 21 react-codemod transforms passing.

Still early. Feedback welcome.

The article discusses the challenges faced by a company during a major software migration, including technical issues, communication breakdowns, and the impact on customers. It highlights the importance of thorough planning, effective communication, and a well-executed rollout strategy to ensure a successful technology transition.

I’m a solo developer from New Zealand and have been building a project called iQWEB over the past few months.

The idea came from a pattern I kept seeing when talking to web designers: tools like Lighthouse and PageSpeed produce a lot of metrics, but turning those signals into something meaningful for client conversations is difficult.

I started experimenting with a deterministic scoring model that analyses performance, structure and security signals and tries to identify the primary constraint affecting a site.

The output is a structured diagnostic report that highlights:

• the primary constraint affecting the site • the fixes most likely to produce the biggest improvement • explanations developers can use when discussing issues with clients

The goal isn’t to replace Lighthouse or PSI but to interpret those signals into something closer to a technical diagnosis.

Curious to hear whether developers think this kind of prioritisation model makes sense or if it misses the point.

The article discusses a case study where a website was able to index 225 pages on Google, with 18% of those pages ranking on the first page, through the use of programmatic SEO techniques. It highlights the effectiveness of this approach in driving organic traffic and visibility for the website.

FairCoding is a platform that provides AI-powered tools and resources to help developers build ethical and responsible AI applications. The article discusses the company's mission to promote fair and transparent AI practices through open-source software, tutorials, and a community-driven approach.

Hey HN, I'm a solopreneur, and I've been banging my head against my keyboard for weeks trying to solve a problem that was driving me crazy: I couldn't scale my YouTube channels.

I have multiple channels, and the workflow was a nightmare: - Recording videos took 20% of my time - Editing, optimizing, scheduling... the other 80% - And still, growth was painfully slow

So I did what any obsessed developer would do: I built something to fix it.

Shortgram takes your long-form content and turns it into optimized short-form clips automatically. Think of it as your video editing co-pilot that actually understands what makes content go viral.

The stack: - Supabase (postgresql + edge functions + jobs) - Using Gemini and Claude - Google Cloud Run to compose the videos

This is the tool I wish I had when I started. I've been using it for my own channels and finally decided to ship it publicly.

Would love your feedback. What features would make this a no-brainer for you?

The article discusses the concept of 'attention capital' and how digital attention should be treated as a valuable, scarce resource. It argues that a micropayment model where users pay a small fee to access content could help address the negative impacts of the attention economy and incentivize the creation of higher-quality, more valuable digital experiences.

I'm a developer looking for well-designed native Mac apps for inspiration.

One example is Pixelmator. It feels so Apple-like that Apple's acquisition of it almost felt inevitable.

I'm curious what other third-party Mac apps people think look and feel like they could have been made by Apple.

The article discusses the emergence of AI liability insurance, which aims to help companies mitigate risks associated with the use of AI systems. It explores the need for such insurance as AI becomes more prevalent in various industries and the challenges in assessing and underwriting AI-related risks.

The article discusses the rise of large tech companies, known as 'Big Tech', and their growing influence on the global economy, politics, and society. It examines the potential risks and challenges posed by the dominance of these companies, including concerns around privacy, competition, and the concentration of power.

The article explores the evolution of human societies, arguing that the Dunbar number, which suggests a cognitive limit on group size, may not fully explain the rise of large-scale civilizations. It suggests that social technologies and cultural innovations have enabled humans to transcend this limit and establish complex, interconnected societies.

Stripe's built-in dashboard doesn't show MRR, churn rate, or LTV. I built a simple dashboard that does.

  You paste your Stripe API key, it pulls your data and shows everything on one clean page:
  - MRR & ARR
  - Churn rate
  - Customer LTV
  - Failed payments
  - Revenue chart (last 6 months)

  Baremetrics charges $129/mo. ChartMogul $199/mo. I'm thinking $19/mo.

  Would you pay for this? Looking for honest feedback before I build more.

As a hobbyist embedded coder, I used a Claude Pro subscription to help with unfamiliar programming tasks. In late May 2025, out of the blue I received an account suspension notice.

The only recourse is to submit a Google Form, which I did. After weeks of waiting, I submitted another. Then over the ensuing weeks and months of silence from Anthropic, I’ve submitted several more of these forms, which enter a black hole, never to emerge. At one point I was able to message with a real, but ultimately unhelpful human. They have since closed that support channel; and now you can only dialogue with an AI chatbot.

Nothing I do is sketchy. At the time of the ban, I was traveling in the U.S. and may have been on a VPN. Possibly that triggered a security issue?

Has anyone successfully reinstated their access? How? Is there some way to talk to an actual human at Anthropic? It’s very dystopian.
