GE Critical Power’s new GP100 Power Supply: Balanced Power. Unparalleled Density. 3-Phase Power. 1RU. Does energy use in your data center keep you up at night? It should. Your customers rely on you to keep networks flowing and transactions moving 24 hours a day, seven days a week, 365 days a year. Your data center can’t afford not to be highly reliable and energy efficient. It’s a tall order. And one we don’t take lightly. Never Balance a Load Again. At GE Critical Power, we understand the issues your data center faces. Chief among these is the burden of balancing the load on the AC grid. Not only does this require a vast amount of resources, but it can add operational costs and the need for additional equipment. Enter the GP100, an innovative new technology that powers the future success of mission critical data centers, telecommunications and supercomputing industries by eliminating single-phase balancing issues and ensuring electrical phases grow in equal increments. More Power. Less Space. GP100 is also extremely compact: four times smaller than competing products on the market today. The most efficient, most compact, and first 3-Phase 1RU Power Supply for 19" Rack Mount Applications Ever Created. Great Power, Great Performance, Great Innovation, Great Reliability and Great Value. All from the engineers and experienced design teams at GE Critical Power.

What If You Never Had to Balance a Load Again? GE’s New GP100 Line of 6-Kilowatt Rectifiers Provides Data-Hungry Applications with Industry-Leading Power Conversion Efficiency Ideal for high-density data and communications settings, the new GP100 AC-to-DC rectifiers feature a power capacity of 6 kW and take up less than half of the space required to install similar products—enabling two GP100s to be mounted together in 1U of rack space. This combination of power capacity and reduced footprint enables GE to provide an industry-leading power density of 12 kW per 1U, making the GP100 the highest density three-phase power supply available today. The GP100 rectifiers also can be paralleled into packaged systems ranging from 12 kW to 432 kW, providing efficient power to high-density and high-capacity applications such as 48-kW power bays and cabinets. This enables these applications to implement three-phase power supplies instead of being limited to less-efficient, single-phase options due to space requirements. With an energy conversion efficiency level of up to 96.5 percent, the GP100 line provides benefits of both operational cost savings and improved total cost of ownership. The new rectifier product line also helps eliminate potential single-phase balancing issues as power requirements grow by ensuring that electrical phases grow in equal increments. GP100: The first 3-Phase 1RU Power Supply for 19" Rack Mount Applications Ever Created. Balanced Load. Unparalleled Density.

The LightConnectTM Fabric V-POD Data Center Architecture

CALIENT Technologies

CALIENT’s LightConnect™ Fabric is a new approach to improving server and storage utilization rates in data centers. It achieves this by allowing Pod resources to be flexibly shared and reassigned at the optical layer in response to the needs of workloads. This is achieved through a new virtual Pod or V-Pod architecture. In a typical V-Pod, some resources are static while others are dynamic – connected through OCS-enabled LightConnect™ Fabric paths to the spine switches rather than directly or through manual patch panels.

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.

PHP Frameworks: I want to break free (IPC Berlin 2024)

Ralf Eggert

In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development. This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

My slides at Nordic Testing Days 6.6.2024 Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.
