The article explains that AI Engineering involves building applications on top of large language models and addresses production concerns such as model cost, context optimization, and latency. ### Source excerpt I released a new course "AI Engineering Fundamentals". 👉 https://www.udemy.com/course/ai-engineering-fundamentals-build-real-llm-apps-in-python/?referralCode=D1BA2721D48381A98F83 Below you can find the story about my transition 👇 Many Android Developers know me as the "Coroutines & Flow Guy", since I have the most popular udemy course on that topic. What few people know is that I haven't worked as an Android Developer Read More The post From Android to AI Engineering first appeared on Lukas Lechner. ## Kotlin Coroutines Course Adds Kotlin Flow Modules for Android Development DevFeed: [Kotlin Coroutines Course Adds Kotlin Flow Modules for Android Development]() Original publisher: [Read original article]() Author: Lukas Lechner Published: 2022-11-21T14:57:43Z Content type: release Language: en Sources: [Lukas Lechner]() Topics: [Kotlin](), [kotlin-flow](), [Coroutines](), [kotlin-coroutines](), [android-development](), [Mobile]() Tags: [allgemein](), [android-development](), [coroutines](), [course](), [flow](), [kotlin](), [kotlin-coroutines](), [kotlin-flow]() ### AI overview The author announces an update to an existing Kotlin Coroutines course for Android, adding modules about Kotlin Flow. The update includes 6 hours of video content, bringing the course to 15 hours in total. ### Source excerpt Hi Readers 👋 There hasn't been a lot of news from my side lately, but today I can announce something big! I spent the last months extending my already existing Course about Kotlin Coroutines for Android with modules about Kotlin Flow! The result is an additional 6 hours of video content about Kotlin Flow, making Read More The post My Coroutines Course just got a BIG update: Kotlin Flow for Android Development first appeared on Lukas Lechner. ## 7 common mistakes you might be making when using Kotlin Coroutines DevFeed: [7 common mistakes you might be making when using Kotlin Coroutines]() Original publisher: [Read original article]() Author: Lukas Lechner Published: 2021-01-08T11:12:53Z Content type: tutorial Language: en Sources: [Lukas Lechner]() Topics: [Coroutines](), [kotlin-coroutines](), [Kotlin](), [Concurrency]() Tags: [allgemein](), [allgemein-kotlin](), [asynchronous](), [concurrency](), [concurrent](), [coroutine](), [coroutines](), [kotlin](), [kotlin-coroutines](), [mistakes](), [structured-concurrency]() ### AI overview A tutorial on common mistakes when using Kotlin Coroutines, including creating a separate Job that breaks structured concurrency and installing SupervisorJob incorrectly. It explains how coroutine scope cancellation and job hierarchies affect cancellation behavior. ### Source excerpt In my opinion, Kotlin Coroutines really simplify the way we write asynchronous and concurrent code. However, I identified some common mistakes that many developers make when using Coroutines. This way, our Coroutine now is cancelled when the Scope is cancelled: The suspend functions in the Kotlin standard library (like e.g. `delay()`) are all cooperative regarding Read More The post 7 common mistakes you might be making when using Kotlin Coroutines first appeared on Lukas Lechner. ## Kotlin Coroutines Exception Handling Cheat Sheet DevFeed: [Kotlin Coroutines Exception Handling Cheat Sheet]() Original publisher: [Read original article]() Author: Lukas Lechner Published: 2020-10-28T14:12:43Z Content type: article Language: en Sources: [Lukas Lechner]() Topics: [Coroutines](), [Exception](), [kotlin-coroutines](), [Kotlin]() Tags: [allgemein](), [allgemein-kotlin](), [cheat-sheet](), [coroutines](), [exception](), [exception-handling](), [kotlin](), [kotlin-coroutines]() ### AI overview A cheat sheet explains six key points about exception handling in Kotlin coroutines, including try-catch handling, exception propagation through job hierarchies, differences between launch and async, coroutineScope behavior, and cancellation exceptions. ### Source excerpt Exception Handling with Kotlin Coroutines is hard. I wrote an extensive article about it and gave talks about it at several conferences. Some developers suggested creating some kind of cheat sheet that could be helpful for implementing appropriate exception handling in coroutine-based code. Here it is 😉. It contains the six most important points.
