Live Webinar and Q&A - Introducing MARA: A Reference Architecture for Kubernetes Microservices (Live Webinar Sept 29th, 2022) Save Your Seat

Facilitating the Spread of Knowledge and Innovation in Professional Software Development

Jordan Bragg discusses using entry-points, breadth-first scanning, and operation tagging to demystify the domain, see where to dive deeper, and uncover what technical debt may exist.

We are talking with Philip Howes about how to get value from your ML model as fast as possible. We will also talk about how to improve your deployed model, and what tools you can use when setting up ML projects. We conclude by discussing how stake holders should be involved, and what makes up a complete ML team.

In a web-based service, a slowdown in request processing can eventually make your service unavailable. Chances are, not all requests need to be processed right away. Some of them just need an acknowledgement of receipt. Have you ever asked yourself: “Would I benefit from asynchronous processing of requests? If so, how would I make such a change in a live, large-scale mission critical system?”

The panelists discuss teamwork from a variety of perspectives, from a traditional office setting to remote-first to a hybrid one, and how to be successful in a productive hybrid team.

At QCon Plus November 2021, Nora Jones, CEO and founder of Jeli, talked about how to build production readiness reviews (PRR) with emphasis on context and psychological safety. Her talk focused on the particulars of a PRR process that relates to incidents.

InfoQ Homepage News Jetpack Compose 1.2 Includes Lazy Grids, Support for Google Fonts, and More

Jetpack Compose 1.2 stabilizes a number of features, including lazy grids, nested scroll, easing curve for animations, and more. In addition, it brings several new experimental features, like custom layouts and downloadable fonts, and fixes many issues.

Lazy grids can be built using the LazyHorizontalGrid and LazyVerticalGrid APIs. Their behaviour is optimized so only visible items are actually presented, meaning only columns or rows that are visible are rendered in memory. The following partial snippet shows how you can define a vertical grid with several items:

Easing curves extends animation speed control, specifically to speed up or down the animating value either at the start or end of the animation. Easing can help to create smoother and more realistic animations. Beside the usual ease in and out curves, many other curves are available, e.g., to emphasize the animation at the end, to accelerate or decelerate it, and so on. The framework also allows to define custom easing curves, like in the following example:

Nested scroll enables embedding a scrollable view within another scrollable view. Nested scroll is usually tricky to get right and Compose provides a nestedScroll modifier that allows to define a scrolling hierarchy so scroll deltas are propagated from inner views to outer views when you reach scroll start or end bounds.

On the front of new experimental features, Compose 1.2 introduces lazy layouts, which could be seen as a generalization of lazy grids. As with lazy grids, lazy layouts only render those items that are actually visible to improve performance and increase efficiency.

Additionally, you can now use Google Fonts in your Android app using the GoogleFont class, which you can instantiate by providing a font name and then use to create a FontRequest.

As mentioned, Compose 1.2 fixes a number of bugs and implements many features requested by the community. For example, it now allows to disable scrolling of lazy layouts, unifies behaviour of TextField and EditText back button, ensures Compose animations honor the animation setting in developer options, and more.

As a final note, it is worth mentioning that updating Compose 1.2 requires Kotlin 1.7.0.
