Wireless LAN Deployment Best Practices

Michael Boman

Aruba AP 270 Series Installation Guide

Aruba, a Hewlett Packard Enterprise company

As presented at the 4G Wireless Evolution conference in Miami, January 22, 2010. WiFI has been at the heart of the change to OFDM and MIMO solutions. It is not suprising that WiFi is a hotbed of innovation in today’s marketplace. This discussion looks at the current and future opportunities associated with WIFI and the implications for new kinds of deployment and adaptation by the LTE and WiMAX community.

Wi-Fi is the new 4G

Brough Turner

Brough’s keynote address at the October 2010 4G Wireless Evolution Conference. In it, he argues: 1. All key 4G technologies are pioneered by Wi-Fi (3-5 year lead!). 2. Wi-Fi will be the dominant solution for mobile data offload. 3. 4G technologies represent a wireless tipping point with the result they will revolutionize backhaul and eventually the first mile (via wireless ISPs). He closes with two slides on his new wireless ISP, netBlazr.

Hadoop: A Hands-on Introduction

Claudio Martella

Building A Scalable Open Source Storage Solution

Phil Cryer

The Biodiversity Heritage Library (BHL), like many other projects within biodiversity informatics, maintains terabytes of data that must be safeguarded against loss. Further, a scalable and resilient infrastructure is required to enable continuous data interoperability, as BHL provides unique services to its community of users. This volume of data and associated availability requirements present significant challenges to a distributed organization like BHL, not only in funding capital equipment purchases, but also in ongoing system administration and maintenance. A new standardized system is required to bring new opportunities to collaborate on distributed services and processing across what will be geographically dispersed nodes. Such services and processing include taxon name finding, indexes or GUID/LSID services, distributed text mining, names reconciliation and other computationally intensive tasks, or tasks with high availability requirements.

Elevating Tactical DDD Patterns Through Object Calisthenics

Dorra BARTAGUIZ

After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!

Why You Should Replace Windows 11 with Nitrux Linux 3.5.0 for enhanced perfor...

SOFTTECHHUB

The choice of an operating system plays a pivotal role in shaping our computing experience. For decades, Microsoft's Windows has dominated the market, offering a familiar and widely adopted platform for personal and professional use. However, as technological advancements continue to push the boundaries of innovation, alternative operating systems have emerged, challenging the status quo and offering users a fresh perspective on computing. One such alternative that has garnered significant attention and acclaim is Nitrux Linux 3.5.0, a sleek, powerful, and user-friendly Linux distribution that promises to redefine the way we interact with our devices. With its focus on performance, security, and customization, Nitrux Linux presents a compelling case for those seeking to break free from the constraints of proprietary software and embrace the freedom and flexibility of open-source computing.

James Anderson

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
