Sue Sheerin: Why self-assessment exciting?

eaquals

The document discusses why self-assessment is an exciting process for organizations. It notes that self-assessment encourages reflection, gives staff a voice, and engages and empowers them. When done properly through preparation, communication, and acting on feedback, self-assessment can foster a learning environment, improve team engagement, develop a culture of quality, and enhance performance. Survey results from organizations that underwent self-assessment showed mostly positive impacts and a willingness to repeat the process going forward.

This document summarizes recent simulations of cold forming processes using the DEFORMTM-3D software. It describes three case studies: 1) the coining of a heat sink with self-contacting surfaces, 2) the assembly of a nut and plate with mesh-to-mesh contact, and 3) the extrusion of a helical gear using rotational symmetry. It also discusses simulations of thread rolling and stress analysis of the threading dies. The case studies demonstrate capabilities for modeling multiple deforming objects, self-contact, and large rotational problems. Finite element simulation has become an integral part of process design in metal forming industries.

Role of Rest vs. Web Services and EI

WSO2

REST is a lightweight architecture for building client-server applications. It uses standard HTTP methods to allow requesting and modifying resource state representations. While SOAP and web services will continue to be used, REST is better suited for mobile and web applications. Organizations are realizing they cannot replace existing technologies and instead focus on integrating technologies to leverage their respective strengths. Exposing existing systems through a REST API gateway allows for coexistence while providing a clean interface. Security, caching, throttling and monitoring are important when managing REST APIs at an enterprise scale.

Craft Conference 2015 - Evolution of the PayPal API: Platform & Culture

Deepak Nadig

PayPal provides a faster, safer way to pay and get paid online, via mobile devices and in stores. With 143 million active accounts in 193 markets and 26 currencies around the world, PayPal enables global commerce, processing more than 9 million payments every day. From its initial product which enabled consumers to exchange money via PDA devices, PayPal has been enabling online merchants to accept secure payments via PayPal, helping users access money in their PayPal accounts via ATM machines and enabling consumers to pay at POS terminals in stores. From enabling simple HTML buttons for the web, PayPal APIs evolved over the last 14 years, and enabled integrations across a variety of channels including mobile, POS, ATMs and other connected devices like televisions and gaming consoles. Through the years, PayPal’s external APIs became increasingly inconsistent, complex and difficult to use, and its internal SOA built on proprietary approaches became tightly coupled and was crippling development. To address these issues, PayPal began developing a new API and Services Platform in 2012 basing it on principles such as API as a Product, API First and loosely coupled services. The new API Platform was initially launched in 2013 to external developers and partners, and is now being used by PayPal’s own developers to build PayPal’s new products and experiences in hours instead of weeks. In this talk, you will learn about how PayPal’s API Platform has evolved both internally and externally, as well as how the company’s culture has changed along with the new API Platform. In this presentation, you will learn about how PayPal’s API Platform has evolved both internally and externally, as well as how the company’s culture has changed along with the new API Platform.

Computational Patterns of the Cloud

The document summarizes a presentation about computational patterns for cloud applications. It discusses four key patterns: 1) Reclaimable resources, where cloud applications provision resources on demand and release them when not needed; 2) Harvesting services, where applications consume external services via APIs to simplify responsibilities; 3) Distributed systems, which are the foundation of infrastructure/services and require awareness of failure theory; and 4) Continuous everything, where the cloud enables continuous delivery through automation and testing. The presentation emphasizes leveraging cloud resources, services, and continuous delivery practices.

Distributed Affordance

Ruben Verborgh

The document proposes an approach called distributed affordance that uses semantic annotations and descriptions to dynamically generate appropriate actions or affordances for resources on the web. It argues that the traditional centralized approach cannot anticipate all possible next steps a client may want to take. Distributed affordance extracts semantic information from representations, matches it to descriptions of services, and instantiates actions based on the user's preferences to add appropriate affordances back to the representation. This allows affordances to be generated on demand for an open world of possibilities rather than being tightly coupled by the publisher.

ScyllaDB Topology on Raft: An Inside Look

Corporate Open Source Anti-Patterns: A Decade Later

A little over a decade ago, I gave a talk on corporate open source anti-patterns, vowing that I would return in ten years to give an update. Much has changed in the last decade: open source is pervasive in infrastructure software, with many companies (like our hosts!) having significant open source components from their inception. But just as open source has changed, the corporate anti-patterns around open source have changed too: where the challenges of the previous decade were all around how to open source existing products (and how to engage with existing communities), the challenges now seem to revolve around how to thrive as a business without betraying the community that made it one in the first place. Open source remains one of humanity's most important collective achievements and one that all companies should seek to engage with at some level; in this talk, we will describe the changes that open source has seen in the last decade, and provide updated guidance for corporations for ways not to do it!

The Strategy Behind ReversingLabs’ Massive Key-Value Migration

ReversingLabs recently completed the largest migration in their history: migrating more than 300 TB of data, more than 400 services, and data models from their internally-developed key-value database to ScyllaDB seamlessly, and with ZERO downtime. Services using multiple tables — reading, writing, and deleting data, and even using transactions — needed to go through a fast and seamless switch. So how did they pull it off? Martina shares their strategy, including service migration, data modeling changes, the actual data migration, and how they addressed distributed locking.

Move Auth, Policy, and Resilience to the Platform

Christian Posta

Developer's time is the most crucial resource in an enterprise IT organization. Too much time is spent on undifferentiated heavy lifting and in the world of APIs and microservices much of that is spent on non-functional, cross-cutting networking requirements like security, observability, and resilience. As organizations reconcile their DevOps practices into Platform Engineering, tools like Istio help alleviate developer pain. In this talk we dig into what that pain looks like, how much it costs, and how Istio has solved these concerns by examining three real-life use cases. As this space continues to emerge, and innovation has not slowed, we will also discuss the recently announced Istio sidecar-less mode which significantly reduces the hurdles to adopt Istio within Kubernetes or outside Kubernetes.

MongoDB vs ScyllaDB: Tractian’s Experience with Real-Time ML

Tractian, an AI-driven industrial monitoring company, recently discovered that their real-time ML environment needed to handle a tenfold increase in data throughput. In this session, JP Voltani (Head of Engineering at Tractian), details why and how they moved to ScyllaDB to scale their data pipeline for this challenge. JP compares ScyllaDB, MongoDB, and PostgreSQL, evaluating their data models, query languages, sharding and replication, and benchmark results. Attendees will gain practical insights into the MongoDB to ScyllaDB migration process, including challenges, lessons learned, and the impact on product performance.

Radically Outperforming DynamoDB @ Digital Turbine with SADA and Google Cloud

Digital Turbine, the Leading Mobile Growth & Monetization Platform, did the analysis and made the leap from DynamoDB to ScyllaDB Cloud on GCP. Suffice it to say, they stuck the landing. We'll introduce Joseph Shorter, VP, Platform Architecture at DT, who lead the charge for change and can speak first-hand to the performance, reliability, and cost benefits of this move. Miles Ward, CTO @ SADA will help explore what this move looks like behind the scenes, in the Scylla Cloud SaaS platform. We'll walk you through before and after, and what it took to get there (easier than you'd guess I bet!).

The "Zen" of Python Exemplars - OTel Community Day

Paige Cruz

The Zen of Python states "There should be one-- and preferably only one --obvious way to do it." OpenTelemetry is the obvious choice for traces but bad news for Pythonistas when it comes to metrics because both Prometheus and OpenTelemetry offer compelling choices. Let's look at all of the ways you can tie metrics and traces together with exemplars whether you're working with OTel metrics, Prom metrics, Prom-turned-OTel metrics, or OTel-turned-Prom metrics!

TrustArc Webinar - Your Guide for Smooth Cross-Border Data Transfers and Glob...

TrustArc

Global data transfers can be tricky due to different regulations and individual protections in each country. Sharing data with vendors has become such a normal part of business operations that some may not even realize they’re conducting a cross-border data transfer! The Global CBPR Forum launched the new Global Cross-Border Privacy Rules framework in May 2024 to ensure that privacy compliance and regulatory differences across participating jurisdictions do not block a business's ability to deliver its products and services worldwide. To benefit consumers and businesses, Global CBPRs promote trust and accountability while moving toward a future where consumer privacy is honored and data can be transferred responsibly across borders. This webinar will review: - What is a data transfer and its related risks - How to manage and mitigate your data transfer risks - How do different data transfer mechanisms like the EU-US DPF and Global CBPR benefit your business globally - Globally what are the cross-border data transfer regulations and guidelines
