The "stdlib" approach to agent engineering is a way to teach a new engineer how to use a tool. The approach is similar to what some companies have as an engineering rulebook. It involves writing down rules/guidelines that could be applied to your project.

DAYS function in Excel is used to calculate the number of days between two dates. The result will be a positive or negative number depending on the order of dates. It is supported in all modern versions of Excel.

how to automate Rust build customization using Cargo metadata and a build script—ideal for projects needing many runtime-configurable variants without duplicating code.

Stablecoins are big in crypto, but earning good, stable returns is tricky. CAP Money is a new project on MegaETH aiming to fix this with a unique "self-enforcing" system where institutions borrow your stablecoins to generate yield, with built-in security for users. You can think of it as easier access to professional investment returns with less risk.

OpenAI announced GPT-4.1, featuring a staggering 1M-token context window and perfect needle-in-a-haystack accuracy. As the founder of a RAG-as-A-service startup, my inbox quickly filled with messages claiming this was the end of Retrieval-Augmented Generation (RAG)

The AI toy box trend exploded online, but most of what I saw was prompted for vibes not engineered for meaning. I decided to do something different. I was going to build a visual artifact’s engineered, iterated, and designed to hold a story.

Several reasons prevent universal access to quality education, and technology has tried to bridge the gap to a large extent.

Many common growth hacks used by Subscription-based businesses are under regulatory fire worldwide. This article talks about which growth hacks will no longer be ethical and what should companies focus on.

eBPF is a Linux technology that allows small, high-performance programs to run directly inside the kernel. The solution was developed to handle spikes of over 300,000 requests per second. The result was lower latency, reduced infrastructure usage, and a more consistent experience.

Cloud companies can't afford to treat AI hardware like traditional infrastructure. The new game is proactive, AI-powered diagnostics—run in-house, at scale, and in real time.

Instead of forcing every team or process to use the same tech stack, build a modular, interoperable pipeline where each function operates independently—but in harmony—via smart orchestration and format-agnostic data adapters.

Lean Tech Stack is a minimalist approach to selecting and using technologies aimed at optimising the development and maintenance of digital products. The main idea is to minimise redundancy and focus on the efficient use of resources — time, money, and human effort. This approach is especially beneficial for startups, which need to quickly enter the market.

This section focuses on the key security parameter—primary committee size—within the Discrepancy Detection (DD) protocol for blockchain security. By estimating the number of faulty participants and committee formations, it ensures that the probability of an entirely faulty committee remains negligibly small, offering a robust security model. DR backup committees are used sparingly with simple majority voting schemes, while an honest majority is crucial for...

Section 6 – Related Work dives into various AI training approaches, categorizing them by whether they use SFT or contrastive losses in offline or online settings.

2 weeks left to participate in the HackerNoon survey and win big prizes! Today, let's look at some of the heartfelt feedback we've received so far.

Artificial intelligence is changing the way we think about art. ChatGPT, DALL·E, and Midjourney all use AI to create works of art. But who owns AI-generated art?

Abhaya Uprety co-founded ParkStash, a startup that makes parking reservations work in a way similar to short-term rental platforms. The company initially focused on a business-to-consumer (B2C) model. By late 2022, it decided on a major pivot: from catering directly to individual drivers to providing a streamlined software solution for parking lot owners, property managers and commercial sites.

The paper emphasizes transaction order finality as key to determining blockchain state. It outlines different finality types—log, transaction order, state, and checkpoint finality—and their role in fault handling. A preliminary Layer 2 design is sketched, discussing trade-offs in achieving these finalities for optimal scalability and security.

Cursor is an AI coding assistant that can be used by developers to speed up their work. In a test project, Cursor built a fully interactive game prototype in under an hour. Cursor is built on language models trained on millions of public code snippets, documentation and developer forums.

Prompt Injection is a top threat to GenAI Large Language Models (LLMs) applications. Tips on how to find these vulnerabilities and protect against them.
