The step to Node is part of I-Tier, a larger project that will allow Groupon to horizontally scale applications by moving toward an SOA and to a more performant stack. As Groupon continues to converge, connect and globalize, Node.js will continue to play an important role. This talk will share key ideas and takeaways from these efforts and outline the resulting business impact. https://vimeo.com/nodesummit/review/85584666/dc3ce37dae
Catherine Hayes, David Malone - Questioning the Criteria for Evaluating Non-cryptographic Hash Functions
Although cryptographic and non-cryptographic hash functions are everywhere, there seems to be a gap in how they are designed. Lots of criteria exist for cryptographic hashes motivated by various security requirements, but on the non-cryptographic side there is a certain amount of folklore that, despite the long history of hash functions, has not been fully explored. While targeting a uniform distribution makes a lot of sense for real-world datasets, it can be a challenge when confronted by a dataset with particular patterns.
Nicole Forsgren, Eirini Kalliamvakou, Abi Noda, Michaela Greiler, Brian Houck, Margaret-Anne Storey - DevEx in Action
DevEx (developer experience) is garnering increased attention at many software organizations as leaders seek to optimize software delivery amid the backdrop of fiscal tightening and transformational technologies such as AI. Intuitively, there is acceptance among technical leaders that good developer experience enables more effective software delivery and developer happiness. Yet, at many organizations, proposed initiatives and investments to improve DevEx struggle to get buy-in as business stakeholders question the value proposition of improvements.
João Varajão, António Trigo, Miguel Almeida - Low-code Development Productivity
This article aims to provide new insights on the subject by presenting the results of laboratory experiments carried out with code-based, low-code, and extreme low-code technologies to study differences in productivity. Low-code technologies have clearly shown higher levels of productivity, providing strong arguments for low-code to dominate the software development mainstream in the short/medium term. The article reports the procedure and protocols, results, limitations, and opportunities for future research.
Ivar Jacobson, Alistair Cockburn - Use Cases are Essential
While the software industry is a fast-paced and exciting world in which new tools, technologies, and techniques are constantly being developed to serve business and society, it is also forgetful. In its haste for fast-forward motion, it is subject to the whims of fashion and can forget or ignore proven solutions to some of the eternal problems that it faces. Use cases, first introduced in 1986 and popularized later, are one of those proven solutions.
Driving Groupon's business to the next level is the move from Ruby on Rails to Node.js.
