Key evidence of this shift in interface design is the adoption of REST by mainstream Web 2.0 service providers—including Yahoo, Google, and Facebook—who have deprecated or passed on SOAP and WSDL-based interfaces in favor of an easier-to-use, resource-oriented model to expose their services. In this article, Alex Rodriguez introduces you to the basic principles of REST. REST defines a set of architectural principles by which you can design Web services that focus on a system's resources, including how resource states are addressed and transferred o

When all the features needed by the users at a given customer are available one could consider this a success. The users have their requirements met and the software vendor has a model that works for them. Unfortunately, there is a problem: All those features that are present in the software but that are not needed by a given user add overhead for the customer and their users. First and foremost, the features are visible and at best may just take up space in menus, toolbars, etc but at worst may confuse the users or make use of required features more complicated. This often translates to lost productivity and increased training effort. The additional features are also likely to result in a higher resource usage, such as memory and storage space as well as network utilisation, which translates into higher capital expenditure for hardware and increased operational costs. https://www.thoughtworks.com/insights/blog/buy-versus-build-shift-issues-buying-software An extreme case is Micros

Nginx do not load runtime lib like .so or binary. Install nodejs.

Not complex but changed frequently also be OK. OO vs complex (big) procedural code.

The main idea was that such a group could keep the practice going without senior engineering leadership bringing an authoritarian flavor to the meetings, and continually model the behavior the practice needed to encourage the multiple perspectives that departures needed. You might be thinking: “but where and when does a decision   get made?” The ARWG’s role was  not  to make a decision. The ARWG’s role was to  create and sustain the conditions where a dialogue can take place , with as many perspectives on both the proble
