The article argues that tests should be considered an integral part of the codebase, rather than a separate entity. It discusses the benefits of this approach, including improved maintainability, better understanding of the system, and more effective refactoring.

The article discusses the Assemble project, an open-source tool that helps developers build and deploy web applications using a declarative configuration file. Assemble aims to simplify the development and deployment process by automating common tasks and providing a consistent infrastructure across different environments.

Built this in a morning with Claude Code.

Images auto-expire after 24h, keeps storage costs at zero. Burn-after-reading deletes on first view. No accounts, no tracking, no cookies.

Cloudflare free tier only (Workers, KV, R2). Domain is the only cost (~$10/yr). No plans to monetise, just wanted to build something with this fun domain.

hi! we're andrew, david, and manas, 3 engineers & ex-roommates. previously, we built things like meta’s self-serve ads platform, scale ai’s ml inference infra, and more.

we’re building Polymorph, which uses AI to help consumer and self-serve apps send the right message at the right time, through the right channel, to maximize conversion.

right now, if consumer apps want to send push notifications or emails to users, they have to write manual queries and build user segments themselves. even then, the message can only get so personalized.

this sucks for both sides:

1. end user gets content that's irrelevant or not helpful 2. builders annoy their users and then they churn

Polymorph is bringing targeting tech that's already in big tech to everyone.

in a few clicks, you could connect your existing analytics stack (PostHog, Datadog, Amplitude, etc), we then build per-user profiles that highlight when they're active, what features they like, and more, our AI agents then decide which channel and times are most likely to increase engagement, and continuously iterate.

we've already seen a 3.6x increase in re-engagement across one customer's churned users, while sending fewer total notifs / emails per person.

over the last month, we've help our customers profile and re-engage millions of users. we're still figuring out our cost structure, so if you're interested, reach out to founders@usepolymorph.com.

The article discusses the evolution of programming and how the concept of 'the loop' has transformed over time, from early programming languages to modern frameworks and architectures. It explores the various approaches to handling loops and control flow in software development, highlighting the importance of efficiency and readability in code.

I've posed this in a couple comments, but want to get a bigger thread going.

There are some opinions that using LLMs to write code is just a new high level language we are dealing in as engineers. However, this leads to a disconnect come code-review time, in that the reviewed code is an artifact of the process that created it. If we are now expressing ourselves via natural language, (prompting, planning, writing, as the new "programming language"), but only putting the generated artifact (the actual code) up for review, how do we review it completely?

I struggle with what feels like a missing piece these days of lacking the context around how the change was produced, the plans, the prompting, to understand how an engineer came to this specific code change as a result. Did they one-shot this? did they still spend hours prompting/iterating/etc.? something in-between?

The summary in the PR often says what the change is, but doesn't contain the full dialog or how we arrived at this specific change (tradeoffs, alternatives, etc.)

How do you review PRs in your organization given this? Any rules/automation/etc. you institute?

The article discusses Pact, a consumer-driven contract testing tool used in software development to ensure the compatibility between different components of a distributed system. It highlights Pact's key features, such as its ability to mock service interactions and verify expectations, as well as its use in facilitating collaboration between service providers and consumers.

Australians have seen a surge in VPN usage as the country begins mandatory age verification for accessing adult content online, raising privacy and security concerns among internet users.

Elon Musk's Xai company has obtained a permit to build a plant in Mississippi despite concerns over pollution, as the state grants the exemption citing economic benefits and job creation.

The article discusses the erosion of global order and the rise of authoritarianism, highlighting how the COVID-19 pandemic has exacerbated existing inequalities and contributed to the breakdown of international cooperation and stability.

This project is still in alpha, but other, more mature, alternatives exist, such as Tunic:

I felt frustrated finding high-signal discussions on HN, and I started this project to better understand how this community actually works.

That led me to build readhn, an MCP server that helps with three things:

- Discover: find relevant stories/comments by keyword, score, and time window

- Trust: identify credible voices using EigenTrust-style propagation from seed experts

- Understand: show why each result is ranked, with explicit signals instead of a black-box score

It includes 6 tools: discover_stories, search, find_experts, expert_brief, story_brief, and thread_analysis.

I also added readhn setup so AI agents can auto-configure it (Claude Code, Codex, Cursor, and others) after pip install.

I’d love feedback on:

1) whether these ranking signals match how you evaluate HN quality,

2) trust-model tradeoffs,

3) what would make this useful in your daily workflow.

If this is useful to you, starring the repo helps others discover it: https://github.com/xodn348/readhn

The article introduces CurlyPrompt, a novel command-line tool that simplifies the task of managing and executing complex shell scripts. CurlyPrompt provides a user-friendly interface, allowing users to easily create, modify, and execute scripts with a focus on maintainability and collaboration.

The article profiles Josh Wardle, the creator of the popular online word game Wordle, and his attempts to solve the challenging New York Times crossword puzzle, which he finds more difficult than creating his own game.

Microsoft's March 2026 Patch Tuesday release addresses a range of security vulnerabilities in its software, including ones in Windows, Microsoft Office, and various enterprise products. The update includes fixes for critical and important issues that could allow attackers to gain elevated privileges, execute remote code, or cause denial-of-service conditions.

The article encourages embracing uncertainty as a natural part of life, arguing that it can lead to personal growth and new opportunities. It suggests that by accepting the unknown and being open to change, individuals can find empowerment and adapt more effectively to the challenges they face.

This article series explores the concept of Automated Empirical Ontologies (AEO), a novel approach to building ontologies that leverages machine learning and automation to make the process more efficient and less time-consuming. The series covers the key aspects of AEO, including its benefits, challenges, and practical applications.

Apple is reportedly planning to return to a traditional scissor-switch keyboard design for its MacBook lineup, moving away from the controversial butterfly keyboard that was plagued by reliability issues. This change is expected to be implemented in future MacBook models, providing a more reliable and comfortable typing experience for users.

Encoding software engineering principles like Outside-in TDD to achieve higher quality tests and implementation.

Lynas Corporation has secured a long-term supply deal with a Japanese trading company to provide rare earth materials. The agreement ensures a stable supply of these critical resources as global demand for rare earths continues to grow.

I'm sure this has been asked a million times, but how can we reach a human at Facebook to plead a case?

Our small Indiana county has a Facebook group. Local news is limited here, so Facebook has become an enormously important means of communication. Some of the commentary in the group gets political, and heated, and that's fine, that's what we're there for. It's an important way for the 16,000 members in this county to know what's going on.

The group got banned, and no one knows why, and there's (practically) no appeal. Just some bot that is programmed to say no.

How can we reach someone to get it turned back on?

This is a big deal in a very small place.
