Nginx Workshop AftermathDenis Zhdanov

This document summarizes Denis Zhdanov's presentation on optimizing and securing Nginx configurations. Some key points include: - Nginx is more scalable than Apache because it uses an event-driven model instead of preforking separate processes per request. - Locations, variables, and directives like proxy_pass, root, and alias allow complex routing and rewriting of requests. Care must be taken to avoid security issues when passing variables to backends. - Caching can be optimized for large static files and many small files through tuning buffers, caches, and disk settings. - Light DDoS attacks can be mitigated using rate limiting, geo blocking, and aggressive caching

PyCon Russia 2014 - Auto Scale in the CloudSimone Soldateschi

Horizontal scaling in the Cloud is the way to adapt resources to load of systems. The Cloud allows users to scale virtually indefinitely, or enough for their needs. This way the number of servers follows trend of requests, and TCO (Total Cost of Owneship) of IT infrastructure can be reduced. Nonetheless companies can avoid dealing with capacity planning and pre-provisioning issues. This talk will show how to use Python and Rackspace/OpenStack API and SDK to implement an event-based scaling solution (software released under the open-source Apache License: stay tuned).

Dark Dynamism: drones, dark factories and deurbanizationJakub Šimek

Startup villages are the next frontier on the road to network states. This book aims to serve as a practical guide to bootstrap a desired future that is both definite and optimistic, to quote Peter Thiel’s framework. Dark Dynamism is my second book, a kind of sequel to Bespoke Balajisms I published on Kindle in 2024. The first book was about 90 ideas of Balaji Srinivasan and 10 of my own concepts, I built on top of his thinking. In Dark Dynamism, I focus on my ideas I played with over the last 8 years, inspired by Balaji Srinivasan, Alexander Bard and many people from the Game B and IDW scenes.

Bepents tech services - a premier cybersecurity consulting firmBenard76

Introduction Bepents Tech Services is a premier cybersecurity consulting firm dedicated to protecting digital infrastructure, data, and business continuity. We partner with organizations of all sizes to defend against today’s evolving cyber threats through expert testing, strategic advisory, and managed services. 🔎 Why You Need us Cyberattacks are no longer a question of “if”—they are a question of “when.” Businesses of all sizes are under constant threat from ransomware, data breaches, phishing attacks, insider threats, and targeted exploits. While most companies focus on growth and operations, security is often overlooked—until it’s too late. At Bepents Tech, we bridge that gap by being your trusted cybersecurity partner. 🚨 Real-World Threats. Real-Time Defense. Sophisticated Attackers: Hackers now use advanced tools and techniques to evade detection. Off-the-shelf antivirus isn’t enough. Human Error: Over 90% of breaches involve employee mistakes. We help build a "human firewall" through training and simulations. Exposed APIs & Apps: Modern businesses rely heavily on web and mobile apps. We find hidden vulnerabilities before attackers do. Cloud Misconfigurations: Cloud platforms like AWS and Azure are powerful but complex—and one misstep can expose your entire infrastructure. 💡 What Sets Us Apart Hands-On Experts: Our team includes certified ethical hackers (OSCP, CEH), cloud architects, red teamers, and security engineers with real-world breach response experience. Custom, Not Cookie-Cutter: We don’t offer generic solutions. Every engagement is tailored to your environment, risk profile, and industry. End-to-End Support: From proactive testing to incident response, we support your full cybersecurity lifecycle. Business-Aligned Security: We help you balance protection with performance—so security becomes a business enabler, not a roadblock. 📊 Risk is Expensive. Prevention is Profitable. A single data breach costs businesses an average of $4.45 million (IBM, 2023). Regulatory fines, loss of trust, downtime, and legal exposure can cripple your reputation. Investing in cybersecurity isn’t just a technical decision—it’s a business strategy. 🔐 When You Choose Bepents Tech, You Get: Peace of Mind – We monitor, detect, and respond before damage occurs. Resilience – Your systems, apps, cloud, and team will be ready to withstand real attacks. Confidence – You’ll meet compliance mandates and pass audits without stress.

Crazy Incentives and How They Kill Security. How Do You Turn the Wheel?Christian Folini

Everybody is driven by incentives. Good incentives persuade us to do the right thing and patch our servers. Bad incentives make us eat unhealthy food and follow stupid security practices. There is a huge resource problem in IT, especially in the IT security industry. Therefore, you would expect people to pay attention to the existing incentives and the ones they create with their budget allocation, their awareness training, their security reports, etc. But reality paints a different picture: Bad incentives all around! We see insane security practices eating valuable time and online training annoying corporate users. But it's even worse. I've come across incentives that lure companies into creating bad products, and I've seen companies create products that incentivize their customers to waste their time. It takes people like you and me to say "NO" and stand up for real security!
