Big Data in Memory - SpringOne 2014
Big Data in Memory - SpringOne 2014John Davies A presentation from SpringOne (Dallas) 2014, the abstract was...
OK so everyone’s into big data but they’re usually talking about persistence, disk or more recently SSD, how about memory? We could simply add a few terabytes of RAM but even at $100 per GB that’s going to cost a LOT. What if we could reduce the size of the data by 50 fold and effectively bring the cost RAM down towards cost of disk? Keep Spring Integration, Spring Batch, GemFire in-memory cache, RabbitMQ messaging but reduce your data down to binary, yes bits and bytes rather than objects. Less garbage, less network overhead, same APIs but big-data in memory. John will show a Spring work-flow consuming 7.4kB XML messages, binding them to 25kB Java but storing them in just 450 bytes each, 10 million derivative contracts in-memory on a laptop.
These slides include some of the code that was demonstrated at the conference but you may find it easier to download it and other papers etc. from http://sdo.c24.biz

Rails Conf Europe 2007 Notes
Rails Conf Europe 2007 NotesRoss Lawley This document summarizes notes from several talks and discussions about scaling Ruby on Rails applications. Some key points include:
- To scale a Rails app, focus on load balancing and separating application tiers (front-end servers, application servers, databases). Use caching, database replication, and queuing systems.
- Monitoring tools like Munin and Nagios are important for tracking performance bottlenecks. Metrics like requests per second help determine capacity.
- Scaling the database is critical; techniques include sharding, replication, and optimizing queries with indexing. Caching data in Memcached also helps scale performance.
- Virtualization allows consolidating servers. Software load balancers like Nginx can route
The Yin and Yang of Software
The Yin and Yang of Softwareelliando dias The document discusses emerging trends in software and services including:
1) Software as a Service and cloud computing which allows software to be delivered and consumed "as a service" with service level agreements.
2) The growth of massive data centers which are becoming large physical assets requiring significant capital expenditures.
3) The rise of "Dev-signers" or designer-developers who are combining development and design skills.
4) The integration of software and services will be key as local software interacts with internet services to provide combined capabilities.

Expecto Performa! The Magic and Reality of Performance Tuning
Expecto Performa! The Magic and Reality of Performance TuningAtlassian In the enterprise there are rarely simple solutions to highly nuanced problems that satisfy all needs. Several customers might each ask "How do I make Jira/Confluence faster?" and each require a different answer. Using this example, this talk will pick apart the inputs, outputs, concerns, and realities of answering a short question with a long answer. We'll then discuss real-world examples from our own internal instances, to give you a taste of the process we've gone through to solve our own performance problems, and to show why there is no simple playbook; "it depends" on a lot! The key takeaways are:
* The importance of having a shared definition of performance
* The importance of having agreed-upon priorities, including what isn't important
* The importance of measuring (allthethings) and understanding them
* The thing you think is the problem might not be the problem, and vice versa.
* The real world and the ideal world tend to look nothing alike!

fennec fox optimization algorithm for optimal solution
fennec fox optimization algorithm for optimal solutionshallal2 Imagine you have a group of fennec foxes searching for the best spot to find food (the optimal solution to a problem). Each fox represents a possible solution and carries a unique "strategy" (set of parameters) to find food. These strategies are organized in a table (matrix X), where each row is a fox, and each column is a parameter they adjust, like digging depth or speed.

GDG Cloud Southlake #42: Suresh Mathew: Autonomous Resource Optimization: How...James Anderson Autonomous Resource Optimization: How AI is Solving the Overprovisioning Problem
In this session, Suresh Mathew will explore how autonomous AI is revolutionizing cloud resource management for DevOps, SRE, and Platform Engineering teams.
Traditional cloud infrastructure typically suffers from significant overprovisioning—a "better safe than sorry" approach that leads to wasted resources and inflated costs. This presentation will demonstrate how AI-powered autonomous systems are eliminating this problem through continuous, real-time optimization.
Key topics include:
Why manual and rule-based optimization approaches fall short in dynamic cloud environments
How machine learning predicts workload patterns to right-size resources before they're needed
Real-world implementation strategies that don't compromise reliability or performance
Featured case study: Learn how Palo Alto Networks implemented autonomous resource optimization to save $3.5M in cloud costs while maintaining strict performance SLAs across their global security infrastructure.
Bio:
Suresh Mathew is the CEO and Founder of Sedai, an autonomous cloud management platform. Previously, as Sr. MTS Architect at PayPal, he built an AI/ML platform that autonomously resolved performance and availability issues—executing over 2 million remediations annually and becoming the only system trusted to operate independently during peak holiday traffic.
How analogue intelligence complements AI
How analogue intelligence complements AIPaul Rowe
Artificial Intelligence is providing benefits in many areas of work within the heritage sector, from image analysis, to ideas generation, and new research tools. However, it is more critical than ever for people, with analogue intelligence, to ensure the integrity and ethical use of AI. Including real people can improve the use of AI by identifying potential biases, cross-checking results, refining workflows, and providing contextual relevance to AI-driven results.
News about the impact of AI often paints a rosy picture. In practice, there are many potential pitfalls. This presentation discusses these issues and looks at the role of analogue intelligence and analogue interfaces in providing the best results to our audiences. How do we deal with factually incorrect results? How do we get content generated that better reflects the diversity of our communities? What roles are there for physical, in-person experiences in the digital world?

Bepents tech services - a premier cybersecurity consulting firm
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.
Expert Guidance – Our team becomes an extension of yours, keeping you ahead of the threat curve.
Security isn’t a product. It’s a partnership.
Let Bepents tech be your shield in a world full of cyber threats.
