This article argues that Substack is structurally designed to prevent guru-style power concentration. By aligning incentives around paid subscriptions instead of advertising, enabling peer-driven discovery, prioritizing ownership and exit rights, and building around long-form, trust-based relationships, Substack creates a distributed “garden” ecosystem. In an era where AI can mass-produce authoritative content, platforms that reward originality, … Read more

When Competition Becomes Clarity I’ve attended dozens of tech festivals. Most follow a familiar rhythm: morning keynotes, afternoon workshops, evening networking with samosas. You leave inspired, maybe connected, but rarely changed. Walking into AI FEST 2026 at Chandigarh University in February, I expected more of the same. What I witnessed instead was something I haven’t … Read more

A new study suggests AGENTS.md-style repo context files can reduce coding-agent success while raising inference cost. Here’s why—and what to do instead.

Safety Is Not a Switch, It Is a Process For a long time, AI safety seemed like something you could install. You specified constraints, tested for edge cases, built guardrails, and deployed with confidence. This paradigm was fine when systems were largely static. It starts to break when systems change. Today, AI systems do not … Read more

Unprocessed emotions act like background apps hogging your brain’s limited working memory, slowing you down even in quiet moments. This fresh lens recasts cognitive overload as emotional RAM drain—and introduces introspection as the ultimate cleaner. Some cognitive models suggest that unprocessed emotions can waste 20–30% of our thinking bandwidth. It’s like trying to ship code … Read more

When you build a thing, especially a software thing, you can always make it more complicated with the hope of making it better.

I Built ArtemisFlow: A Local-First Job Tracker for Tech Candidates Modern hiring processes often involve multiple companies, stages, and timelines happening in parallel. At some point, keeping track of everything becomes harder than it should be. Like many developers, I initially used spreadsheets. They worked well enough in the beginning. But over time, they became … Read more

Most Web3 projects don’t have a community problem. They have a trust problem. And the fastest way to destroy trust is to treat the community like a growth tactic. In crypto, it’s easy to confuse noise for health. A Discord full of messages. A Telegram that never sleeps. A timeline full of engagement. But anyone … Read more

Price localization—charging different amounts by country—can unlock meaningful global growth, but only when grounded in purchasing power rather than GDP. While it increases operational complexity, SaaS companies with product-market fit and scalable channels should consider tiered international pricing once unlocking new markets could drive at least 15–20% incremental revenue. The key is grouping countries by … Read more

When revenue slows, most founders default to shipping more features. But subscription growth only comes from three levers: acquiring more users, increasing revenue per user, or extending retention. The true ceiling on revenue is determined by the underlying problem you solve and how valuable that problem is to different user personas. Instead of building more … Read more

The transition marks a pivotal stage in the platform’s growth trajectory, … Read more

Subscription businesses compound monthly, which makes sequencing more important than volume. Instead of launching multiple projects at once, teams should prioritize low-risk, fast, bottom-layer optimizations—like churn reduction and payment flow fixes—before tackling high-uncertainty initiatives such as pricing or new feature bets. By focusing on quality, clarity, and best practices first, companies can bank reliable wins, … Read more

Subscription products benefit from recurring revenue, durable cash flows, and historically strong valuation multiples, but they face structural challenges: unpredictable lifetime value, natural churn ceilings, and slower revenue scaling compared to high-ticket B2B or e-commerce models. The winners don’t chase silver bullets—they compound small product and acquisition improvements over time.

Remember that moment you watched an AI generate text token-by-token? It felt like magic. You could see the thought process unfold, the sentences building in real-time. It was a huge leap from the static, wait-for-the-whole-message experience. But let’s be honest — it was also a bit like watching someone else use a computer. The AI was a … Read more

When a user picks up a smartphone or camera and takes a quick shot in “auto mode,” a perfectly exposed, color-accurate, and sharply focused photo is instantly generated. Behind this magical moment lies the camera’s Image Signal Processor (ISP) and its core “decision intelligence” ‒ the 3A algorithms ‒ working tirelessly. 3A refers to Auto … Read more

If a two-week sprint costs $50K, it must pay for itself. This article outlines four low-effort, high-impact product changes—improving checkout error clarity, activating payment recovery systems, defaulting to annual plans, and disabling monthly receipts—that can drive immediate revenue gains and compound over time for subscription businesses.

The system prompt for Claude Opus 4.6 is out in the wild, and it’s more than just a list of “don’ts.” For developers and security engineers, it’s a blueprint for how frontier models are evolving from simple chatbots into autonomous agents capable of navigating GUIs, executing code, and managing complex workflows. n While the industry … Read more
