Hey hackers!  If you’ve ever wondered why some of your submissions take a while before they get published, it’s probably because you’re submitting incomplete articles.  While most contributors focus on the content and the headline, we often receive submissions that are missing their meta, TL;dr, and keyword sections. Worse yet, sometimes contributors will add some … Read more

In an environment of perpetual digital noise, geopolitical friction, and algorithmic manipulation, many users have lost faith in the integrity of the information they see. The information landscape is saturated, blurring the lines between ordinary discourse and strategic misinformation by companies or states. If high-stakes decisions (from investment strategies to international security choices) are based … Read more

Data engineering exists because production databases are built for fast transactions (rows), while analytics requires massive scans (columns); trying to do both on one system can crash your business and cost millions.

Crypto contract verification is the definitive proof of identity in the DeFi ecosystem, transforming opaque bytecode into trusted logic. However, the process is often misunderstood, leading to frustration when the “Deterministic Black Box” of the compiler produces mismatching fingerprints. This article demystifies verification by visualizing it as a “Mirror Mechanism,” where local compilation environments must … Read more

I. The “Complete System” Fallacy 1.1 The Problem The pursuit of ethical Artificial Intelligence (AI) has been defined by a single, implicit ambition: the creation of a “complete” ethical machine. This is the dream of building an autonomous system whose internal logic, training data, and reward functions are comprehensive enough to resolve any moral dilemma … Read more

Marcus Briggs has walked into gold vaults on three continents. The first time, in Dubai nearly fifteen years ago, I expected armed guards, heavy doors, maybe a few cameras. What I found was something closer to science fiction. Retinal scanners, mantrap airlocks, pressure-sensitive flooring that could detect an extra kilogram of weight. The gold itself … Read more

Why Innovators, Builders, and Workplaces Need to Operate at the “Edge of Chaos” Innovation doesn’t emerge from perfectly controlled systems. Builders and entrepreneurs thrive in environments where assumptions are challenged, information is incomplete, and outcomes are inherently unpredictable. This is the state known as the “edge of chaos.” Builders operate under uncertainty by default. Progress … Read more

In Part 1, a smart account was deployed and the first UserOperation successfully executed through the EntryPoint. At that point, everything worked — but a critical part of the system stayed mostly invisible: the bundler. Bundlers are the bridge between account abstraction and the Ethereum execution layer. They take UserOperations from a separate mempool, pay … Read more

A few years ago, AI in marketing seemed like a luxury for big companies. Now, startups without AI are often at a disadvantage. There are approximately 333.34 million companies worldwide. According to research, over 90% of companies are either using or exploring the use of AI. This means that over 300 million companies are using or exploring AI … Read more

Meta’s Scam Ads Are Finally Being Challenged — And It’s Long Overdue After years of warnings from consumer advocates, regulators and defrauded users, Meta Platforms is finally being dragged into court over what critics say has been an open-secret business model: knowingly allowing scam advertisements to run across Facebook and Instagram in the name of … Read more

When you go to the doctor, one thing you may have noticed is how trash is handled. Usually, there are multiple trash cans for regular waste and biohazard waste. While this is done to prevent contamination to other individuals, it is also very costly for medical providers if they fail to properly dispose of their … Read more

The crypto market is no longer driven purely by hype. As investors look ahead to 2026, the focus has shifted toward timing, utility, and long-term sustainability. In this article, we take a closer look at Dogecoin (DOGE) and Mutuum Finance (MUTM)—two very different cryptocurrencies at very different stages—to assess which may offer the stronger investment … Read more

In a year where politics and technology are increasingly intertwined, enterprise software firms face a new kind of reckoning—not just with regulation or competition, but with identity. As the market sorts itself between values-driven and mission-driven clients, the question isn’t who’s right. It’s who’s clear. The Sorting, Not the Shift Project 2025, a policy blueprint … Read more

Last month, I spent 3 hours trying to write a decent cold email template. Three. Whole. Hours. The AI kept spitting out generic garbage that sounded like every other “Hey [FIRST_NAME], hope this email finds you well”… Then I changed one thing in my prompt. One thing. Suddenly, the AI was writing emails that actually … Read more

This document was adapted from Dagger Directives for a monorepo that uses Bazel Build, and is provided for ease of use in other organizations. Contents This document is extensive, and while each directive is simple, the broader architecture they promote may be unclear; therefore, an end-to-end example is provided to aid comprehension, and the underlying … Read more

After spending months studying transformer architectures and building LLM applications, I realized something: most explanations are overwhelming or missing out some details. This article is my attempt to bridge that gap — explaining transformers the way I wish someone had explained them to me. For an intro into what Large language model (LLM) means, refer … Read more

We interviewed a dozen(ish) expert tech bloggers over the past year to share perspectives and tips beyond Writing for Developers. The idea: ask everyone the same set of questions and hopefully see an interesting range of responses emerge. They did. You can read all the interviews here. We’ll continue the interview series (and maybe publish some book … Read more

There’s a strange feeling that washes over you when you witness something you’ve created take on a life of its own. It’s not just pride; it’s a deep, almost philosophical resonance. That’s the feeling I’ve carried since my “Auto-Painter Robot Brain” completed its first masterpiece. What began as a simple coding exercise evolved into a … Read more

A leading Shenzhen manufacturing enterprise uses #ApacheDolphinScheduler to standardize data pipelines and deploy dozens of factories in a single day—with visual DAGs, template-based workflows, and decentralized scheduling.

Internal API platforms are no longer plumbing. This article explains how a platform-led API strategy reduces complexity, governs AI execution, and accelerates business velocity.

AI features don’t fail at launch, but they perform the best on day one. Unlike traditional software, AI systems deteriorate due to model drift, stale data, and evolving user behaviour. Early launch metrics do not quite capture the nuances of AI features and can create a false sense of success. After launch, PMs are likely … Read more

IAM often creates a false sense of security. Hidden anti-patterns like excessive privileges, shared identities, and stale credentials silently grow, increasing breach risk unless continuously monitored and governed.

AI is no longer a future consideration in marketing. It is already embedded across workflows, quietly shaping how campaigns are created, optimized, and scaled. For many teams, AI has become part of the default operating model rather than an experimental layer. Yet despite similar access to tools, outcomes vary widely. Some teams use AI to … Read more

Cloud migrations break in places that dashboards do not measure. AI exposes every inconsistency your architecture has accumulated and the next phase belongs to teams that tighten the weak links, steady the routing paths, and keep the system coherent when the pressure rises.
