I analysed over a year’s worth of reddit posts to figure out what’s working for founders as far as online payment gateways are concerned. You can check the full thing out here. However, here’s a summary of what other founders on reddit recommend if your SaaS is still in its early stages. Chargebee: Free plan up to $100k ARR BillaBear: Free self-hosted option Lemon...

This hands-on guide walks you through a real production upgrade with clear steps, SQL scripts & troubleshooting tips.

This playbook exposes you to ideas on how to resuscitate a once vibrant web3 gaming community by focusing on intricate touchpoints such as user persona, strategy, incentive structure and timeline.

Unchecked AI could be the “Great Filter” for civilizations. Urgent global regulation is key to humanity’s-and the galaxy’s-long-term survival.

Global AI regulation is critical but faces huge challenges; unchecked, AI autonomy could pose existential risks for all technical civilizations.

Drake Equation analysis suggests tech civilizations’ communicative phases are brief, supporting rare SETI detections and a possible “Great Filter” from AI risks.

Spreading life (and AI) across planets boosts resilience to existential risks, but AI advances far outpace humanity’s slow progress toward multiplanetary living.

Digital twins have evolved across sectors—mobility, smart cities, health, and industry—each with unique implementations and challenges. This section reviews key variants, including spatial digital twins like mobility and urban twins, and analyzes their case studies. Also discussed: human twins for health management, industrial automation, and energy sector integration.

Want to reach over 400,000 tech-savvy readers without spending five figures? HackerNoon’s daily newsletter offers affordable, high-impact ad placements with 500 to 1000 leads per send, an average CPC of just $0.50, and access to a highly engaged, mostly US-based tech audience.

Spatial Digital Twins require four tech layers: (1) data acquisition/processing, (2) spatial data modeling & management, (3) GIS software & APIs, and (4) core functions (visualization, simulation, query). This paper distinguishes SDTs from traditional twins, proposes the layered framework, analyzes AI/ML and blockchain enablers, and outlines future research directions.

Respondents feel their privacy has improved under GDPR. ICO recognition rose (21%→38%) yet isn’t crucial. People see the ICO as a punisher, though few recall fines. Privacy gains drive “worth it” beliefs—especially among those confident in rights, aware of powers, and who’ve seen positive workplace changes. Implications span theory (risk of compliance decay), management (ongoing training), and policy (positioning the regulator and harnessing dual‑role...

Discussion shows employees are highly aware of GDPR, form opinions only after specific prompts, and recognize both the security benefits and bureaucratic costs—explaining strong overall support.

When asked, staff split on GDPR’s day‑to‑day drawbacks (bureaucracy, costs) but mostly see data‑security and clarity upsides. Almost everyone agrees GDPR benefits their company. A regression shows that feeling more private drives overall “worth it” approval (model R² = 0.687).

I have now built two apps using this stack, one of them being a browser-based party game. I want to keep things as simple as possible. This stack might not make sense for you.

Landed my job via LinkedIn, where companies often hire. Ghost jobs happen due to ATS rejections and no follow-up emails. To avoid ghosting, apply within hours of a posting.

Building data observability into a data pipeline should be a standard practice, but many engineering teams still don't spend enough time on it. In this article, I've presented a list of tried-and-tested tools that would help with building a data observability framework (including the not-so-obvious options) and explored both the practice's past and future.

Caching tiers were introduced because it was too slow for applications to read the required data directly from a relational database. Most relational databases were designed 50 years ago when an enterprise would run the database and any applications in a single data center. Fast forward to today, when enterprises and customers are spread worldwide, with everyone wanting to work with the same data.

In this article, we mainly focus on the paper, “Risk-Sensitive Compact Decision Trees for Autonomous Execution in Presence of Simulated Market Response”. We discuss how Machine Learning helps us get a better execution strategy.

⚫️ Founders who only listen to "stated reasons" from industry players are often playing a game where the real rules are kept hidden from them. ⚫️ 'Deep Dialogue' isn't about arguing or aggressive questioning; it’s about dissecting conversations until the actual unspoken logic and 'invisible rules' driving an industry finally surface. ⚫️ If you don't uncover the hidden playbooks of gatekeepers (like VCs), you'll...

The taskbar is an essential part of the Windows 11 experience, offering quick access to apps, settings, and system notifications. Some users prefer to hide this taskbar for an enhanced experience. The following are the different methods to automatically hide the taskbar on Windows 11.

DNA testing company 23andMe suffered a data breach in late 2023. The breach exposed deeply personal insights that are impossible to reset. It shattered assumptions about consumer genetics platforms and ignited regulatory scrutiny.
