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.

The experiments evaluate the DNO algorithm (specifically, DNO-Prct) using an iterative training process that combines GPT-4-Turbo scoring with curated pairwise comparisons. UltraFeedback forms the core dataset, with additional large-scale trials. Evaluation is done using AlpacaEval 2.0, MT-Bench, and OpenLLM Leaderboard. The results highlight how DNO approaches state-of-the-art performance through efficient, scalable preference modeling.

ShopCTL lets you easily manage your Shopify store via the command line, offering quick commands to access your store’s data right from your terminal.

A full-stack guide to building a secure, real-time polling app with authentication, per-user permissions, and dynamic policy checks—using Supabase + Permit.io.

When I joined my last company, we were just 20 people, figuring things out as we went. Three years later, we had over 200 employees, thousands of paying customers, and a growing list of features, expectations, and bugs. How we navigated fast growth without losing clarity, culture, or product quality.

In Layer 2 rollups, data availability is crucial for transaction processing. CallData is stored on-chain, while state representations use cryptographic commitments. The system integrates garbage collection mechanisms, efficiently reclaiming older data post-checkpoint finality. A decentralized scheduler can enhance transaction ordering and state finality while ensuring low-cost, high-security operations. Checkpoints balance failure recovery with efficient data storage management.

Last week, Google introduced its AI copilot Firebase Studio, and I decided to give it a try. It got me thinking about what I want to do next.

The article explores the environmental challenges posed by traditional cryptocurrencies and delves into the potential of CBDCs to mitigate such issues. By analyzing the energy consumption, technological designs, and regulatory frameworks, the article sheds light on the prospects and challenges of implementing sustainable CBDCs.

This section introduces DNO-Prct, a practical and scalable implementation of Direct Nash Optimization. It leverages iterative contrastive learning—similar to DPO—but is designed for batched on-policy training with general preferences. By implicitly using reward signals and structuring pairwise comparisons, DNO-Prct enables efficient self-improvement and approaches Nash equilibrium in complex AI preference models.

This story talks about how to determine right goals for your systems and explains them through SLI,SLO and SLAs

P2P lending platforms are fast becoming the way forward. People can now easily borrow and lend money to others without middlemen receiving a massive cut or the loan disbursement taking forever to happen. Despite these improvements, the coast still isn’t clear. Some P2P platforms are still clunky, loan processing is still slow, and *Mr. Fraud* still says hello.
