OpenResty: a Swiss Army Proxy for Serverless WAL, Slack, Zapier and Auth

A while ago Tom Larkworthy started writing an identity aware proxy (IAP) to secure a binary with authentication. However, what started as a minimal auth layer has grown with features. What he has come to appreciate is that the reverse proxy is a great layer to do a variety of cross-cutting concerns like auth, at-least-once delivery and adapting. Furthermore, he found that OpenResty provides amazing performance and flexibility, AND it fits the serverless paradigm almost perfectly.

Data structures for fast autocomplete

Autocomplete is a feature that suggests a complete word or phrase after a user has typed just a few letters. The feature increases text input speed especially on mobile devices, because one doesn't have to type every letter in a word. Autocomplete functionality is commonly found on search engines and messaging apps.

A good autocompleter must be fast and update the list of suggestions immediately after the user types the next letter. This blog post studies algorithms and data structures that are necessary for attaining a satisfactory speed.

7 design principles for IoT

For designers focused on designing SW services and screen based interfaces or physical products, designing IoT solutions creates totally new design challenges. IoT solutions consist of multiple elements: physical devices like sensors, actuators and interactive devices, the network connecting these devices, the data gathered from these devices and analyzed to create a meaningful experience and last but definitely not least, the physical context in which user interacts with the solution.

You need to do various types of design, from industrial product design to service and business design. All of these factors have their impact on the total UX of the IoT system and the task of designing in this context may feel quite overwhelming. To make it a little easier, Heli Ihamäki has gathered her list of the 7 most important design principles for IoT.
