Project Loom is a new Java-based platform that allows for the creation of virtual threads. These threads can be used to speed up workflow and improve scalability. The first preview of the project will be available in March 2019.

  • 00:00:00 Project Loom is designed to help developers write service-oriented applications more effectively, by providing a universal way to manage concurrent requests.
  • 00:05:00 Project Loom is a web application platform that uses a thread per request model, in which every request runs from start to finish on a thread. This allows for high throughput, but can be difficult to scale, due to the number of threads required. Asynchronous code allows for scalability by handling requests asynchronously and returning threads to the pool when i operations complete.
  • 00:10:00 Project Loom is a platform that allows developers to write simple code that is both harmonious with the platform and scalable.
  • 00:15:00 Project Loom is a platform that allows for the creation of virtual threads, which allow for increased throughput. Virtual threads have the same limitations as platform threads, in that they can only handle a certain number of concurrent requests.
  • 00:20:00 Project Loom is a new mesh networking technology that allows thousands of things to be done concurrently. Virtual threads are used to improve performance over platform threads, and there is no difference in performance between using virtual threads and using threads per request. However, at a larger scale, native monitors will block the underlying os thread, so if you need to do long-lived IO operations, you might want to switch to a JavaUtil concurrent lock.
  • 00:25:00 Project Loom is a woven fabric project that allows for the creation of custom designs using computer-generated instructions. The first preview of the project will be available in March 2019, and full GA will be released in September 2019.
  • 00:30:00 Project Loom is a Java development project that consists of three features: virtual threads, structure concurrency, and scope locals. The first two features are relatively new and are still in development, while the third, virtual friends, is a relatively minor change to the Java API.
  • 00:35:00 Project Loom is a Java-based framework for developing scalable, concurrent applications. Its goal is to make the codebase more understandable and easy to read, while also providing mechanisms for the runtime to understand what is happening.
  • 00:40:00 Project Loom is a software development platform that allows for the concurrent execution of multiple tasks. Structured concurrency is a feature of Project Loom that ensures that the threads spawned for a task are guaranteed to have completed by the time the task exits. If an error occurs during the execution of a task, the task's thread is automatically cancelled.
  • 00:45:00 Project Loom is a platform for creating threaded applications. It is similar to other programming languages in that it has user mode threads, but there are some differences. One important difference is that Go has no reference to threads, while Java has a thread object. Another difference is that Go does not have a sound protocol for communicating with threads, while Java does.
  • 00:50:00 Project Loom is a Java-based tool that allows users to create virtual threads to speed up their workflow. Users should use thread builders or executors to create new threads, and should avoid using new threads for every task.
  • 00:55:00 Project Loom is a virtual threading framework that allows for scalability and performance similar to reactive frameworks, but without the need for manual thread management.

Ron Pressler of Project Loom gives a quick overview of the platform and some of its features. He shares that his favorite language to work with on the platform is closure, and praises the App Store and Spaces for their usefulness in developing mobile apps.

  • 01:00:00 Project Loom is a new type of social network that allows users to share threads of text with one another. Virtual threads are not expensive, so there is no reason to pull them, but they can perform another task which is sort of accidental. If users have a pool of 100 threads, they know that at most it can do 100 things concurrently. Instead of using virtual threads, users can use semaphores to limit the number of concurrent calls to a specific method. This makes it safer and more appropriate for long-running tasks. Ron Pressler's favorite programming language is C++, and he has written message code in that language for several years ago. He currently writes most of his tests in VS Code, but sometimes he uses Netbeans and Intellij for longer tasks. His favorite drink is beer and his favorite programming language is fluent in c++, assembly, and zig.
  • 01:05:00 Project Loom is a platform that allows developers to create mobile apps in a variety of languages, including Haskell, Scala, Kotlin, and Matlab. Ron Pressler, the project's translator, tells the audience that his favorite language to work in is closure, and he enjoys using the App Store and Spaces as tabbed or space-based browsers.
