Harper 5.0 makes its core fully open source under Apache 2.0, adds RocksDB alongside LMDB, and doubles down on its unified runtime for agentic engineering. By combining database, cache, messaging, and logic into a single process, it reduces latency and simplifies deployment. Built for AI-driven development, it enables faster, cheaper, and more scalable applications.

App Switch architecture on iOS allows one app to hand off execution to another and resume the flow through callbacks, but reliable implementation requires treating the interaction as a distributed transaction rather than simple navigation. Strong state management, secure deep linking using Universal Links, strict callback validation, and backend verification are critical to prevent failures and security issues. Observability and transaction-level tracking further enable performance optimization and production reliability.

A new system automates the migration of legacy SAS scripts to PySpark for enterprise clients. The system was built with deterministic parsing to understand the source code. Structured pattern extraction to capture business-critical data. Validation pipelines to catch what the LLM gets wrong.

The term "cloud-native" has been diluted by marketing. Here's what it actually means and the honest checklist to find out where your stack stands.

This article argues that large context windows are not a substitute for proper memory in AI agents. Instead, effective systems rely on layered memory architectures—working, session, condensed, durable, and retrieval memory—to manage context growth, reduce cost, and improve accuracy. By focusing on memory lifecycle design rather than raw context size, developers can build more reliable, scalable agents that avoid common failures like repetition, context drift, and missed recall.

You know code coverage helps you see what code is running. But with mutation tests, you get to see what your tests are actually capable of catching. An AI-written code will pass any code coverage tool with ease, but 15-25% more code will pass a mutation test, indicating your tests are not as good as they look on a code coverage report.

Cayuse integrates PlayerZero across its 20+ apps to proactively identify and fix issues before they reach customers. The AI platform connects code, logs, and user sessions, reducing ticket resolution times by 80% and freeing engineers to focus on long-term improvements. By unifying support, product, and engineering teams, Cayuse boosts productivity, accountability, and customer satisfaction.

The shift from traditional search to AI-powered discovery is no longer future talk — it’s reshaping marketing right now.

A brilliant entomologist, Hapley, locked in a lifelong rivalry with Pawkins, becomes psychologically destabilized while studying moths. After Pawkins dies, Hapley's obsessive conflict finds a new target in an unknown moth that appears to only he can see. The insect becomes a projection of rivalry and obsession, driving him into violence and hallucination, ending in confinement.

In a Camberwell dynamo shed, Holroyd, a violent electrician, and Azuma-zi, an immigrant stoker, work amid roaring machines. Azuma-zi worships the largest dynamo as a living god, reading its noises as divine will. After abuse by Holroyd, he believes sacrifice is demanded. The machine kills Holroyd in an accident. Azuma-zi attacks a manager and dies by electrocution, ending the cult of machine worship in London.

After a lightning strike in a laboratory, Sidney Davidson loses normal sight and instead sees a remote island thousands of miles away in real time. Blind to his surroundings, he experiences another world overlapping reality. Weeks later he recovers—but evidence proves his visions were real, hinting at a terrifying possibility: sight can exist independent of the body across space.

Market timing receives 10% weight in Proof of Usefulness scoring — the second-lowest weighting in the framework. This is a deliberate choice that reflects a specific analytical judgment: timing is real, consequential, and mostly outside founder control. Penalizing teams heavily for factors they cannot meaningfully influence would make the framework less honest, not more rigorous. The 10% weight acknowledges timing without allowing it to dominate an evaluation that should primarily measure what teams actually built and whether it actually works.

Albania’s high yields may hide legal opacity, title disputes, and capital repatriation risk. Here’s what UHNI investors need to watch.

Israeli real estate investors face a brutal math problem: borrowing at 6% to earn just 3%, turning property into a speculative bet.

While the US treats AI payments as a retail novelty, China is building a state-backed, e-CNY-powered autonomous financial ecosystem to bypass Western systems and dominate global trade.

The AI identity crisis isn't about losing your job. It's about the job becoming hollow while you're still in it.

A solo founder with ADHD explains how seven half-built apps happened, why only two survived, and what systems actually made them work.

Plus: The FBI says a recent hack of its wiretap tools poses a national security risk, attackers stole Cisco source code as part of an ongoing supply chain hacking spree, and more.

The Quizlet flashcards, which WIRED found through basic Google searches, seem to include sensitive information about gate security at Customs and Border Protection locations.

More open-source developers are finding that, when used properly, AI can actually help current and long-neglected programs. However, legal and quality issues loom.

Why is the biggest name in AI late to the AI coding revolution?

But AI also creates bugs - about 1.7 times as many as humans, including critical and major issues.

AI has turned security triage into 'terror reporting,' draining time, attention, and the 'will to live.' But, used right, it can help. Here's how.

Linux kernel maintainers propose a less painful process for identifying developers. See how it can make Linux code safer than ever.

Postcodes After a pretty practical previous post about records and collections, this post is less likely to give anyone ideas about how they might tackle a problem in their own project, and doesn’t have any feature requests for Microsoft either. It’s an area I’ve found really fun though. An introduction to postcodes in the UK … Continue reading Election 2029: Postcodes →
