• Face and Voice Recognition on MCUs: The Edge AI Coffee Machine Challenge

  

  Imagine a scenario - it’s Monday and you just arrived at the office at 7:55 AM since you have a meeting at 8 AM. What kind of person schedules a meeting at 8 AM? Everything is a pain and a hardship. You can barely see, but your smart coffee machine is your friend. It knows who you are and what your favorite drink is, it understands you, but doesn’t judge. It can’t give you a hug, but it can quickly brew you a cup of warm and fresh cup of your preferred beverage, helping you survive that meeting and come back to the land of the living.

• REST Better with the Support of OpenAPI in Qt 6

  

  Some of you are following our works to improve connectivity of Qt-based apps. For example, in this blogpost we explained enhacements in the Qt's network stack for more efficient use of RESTful APIs starting with Qt 6.7. So, it might sound we are done with REST. Why bother about OpenAPI then? Well, while around 70% of all web services run on REST, around 20-30% of them use code generated from OpenAPI specification. How could Qt leave that out without helping our users to code less and create more? 

  The new Qt 6 OpenAPI module will become available with Qt 6.11 as a Technology Preview. The module introduces the Qt 6 OpenAPI generator, which generates Qt HTTP clients using Qt Network RESTful APIs.

  It is important to note here that an OpenAPI generator for Qt 5 has been originally developed by the OpenAPI community. We took it into Qt 6, refactored it, and extended it.

  In this blog post, you will learn about the new OpenAPI generator in Qt 6 and see how the new module can be used to implement a simple, Qt-based ChatGPT client application using specification of its API provided in the OpenAPI format.
