Although paper is a more environmentally friendly packaging material than plastic, it's often contaminated with additives, such as adhesives used to create a secure seal. That complicates the recycling process and reduces the quality of recycled paper. Now, German researchers at four Fraunhofer institutes have developed an alternative process that can seal paper packaging without […]
The launch of the Google Pixel 11 is still months away, but leaked renders shared by Android Headlines may give us an idea of what to expect. Based on the images, the Pixel 11 could come with slimmer bezels than its predecessor, along with a completely black rear camera bar. The Pixel 10, which launched […]

Amazon loves to manufacture an event. March is historically a dry spell for deals; however, with Amazon’s third annual Big Spring Sale, which runs through tomorrow, March 31st, the retail behemoth is hoping to lure in would-be shoppers with the promise of steep(ish) savings and discounts on more seasonal, spring-centric items to hold folks over […]
Hi HN - We've been working on Coasts (“containerized hosts”) to make it so you can run multiple localhost instances, and multiple docker-compose runtimes, across git worktrees on the same computer. Here’s a demo: https://www.youtube.com/watch?v=yRiySdGQZZA. There are also videos in our docs that give a good conceptual overview: https://coasts.dev/docs/learn-coasts-videos.
Agents can make code changes in different worktrees in isolation, but it's hard for them to test their changes without multiple localhost runtimes that are isolated and scoped to those worktrees as well. You can do it up to a point with port hacking tricks, but it becomes impractical when you have a complex docker-compose with many services and multiple volumes.
We started playing with Codex and Conductor in the beginning of this year and had to come up with a bunch of hacky workarounds to give the agents access to isolated runtimes. After bastardizing our own docker-compose setup, we came up with Coasts as a way for agents to have their own runtimes without having to change your original docker-compose.
A containerized host (from now on we’ll just say “coast” for short) is a representation of your project's runtime, like a devcontainer but without the IDE stuff—it’s just focused on the runtime. You create a Coastfile at your project root and usually point to your project's docker-compose from there. When you run `coast build` next to the Coastfile you will get a build (essentially a docker image) that can be used to spin up multiple Docker-in-Docker runtimes of your project.
Once you have a coast running, you can then do things like assign it to a worktree, with `coast assign dev-1 -w worktree-1`. The coast will then point at the worktree-1 root.
Under the hood the host project root and any external worktree directories are Docker-bind-mounted into the container at creation time but the /workspace dir, where we run the services of the coast from, is a separate Linux bind mount that we create inside the running container. When switching worktrees we basically just do umount -l /workspace, mount --bind The main idea is that the agents can continue to work host-side but then run exec commands against a specific coast instance if they need to test runtime changes or access runtime logs. This makes it so that we are harness agnostic and create interoperability around any agent or agent harness that runs host-side. Each coast comes with its own set of dynamic ports: you define the ports you wish to expose back to the host machine in the Coastfile. You're also able to "checkout" a coast. When you do that, socat binds the canonical ports of your coast (e.g. web 3000, db 5432) to the host machine. This is useful if you have hard coded ports in your project or need to do something like test webhooks. In your Coastfile you point to all the locations on your host-machine where you store your worktrees for your project (e.g. ~/.codex/worktrees). When an agent runs `coast lookup` from a host-side worktree directory, it is able to find the name of the coast instance it is running on, so it can do things like call `coast exec dev-1 make tests`. If your agent needs to do things like test with Playwright it can so that host-side by using the dynamic port of your frontend. You can also configure volume topologies, omit services and volumes that your agent doesn't need, as well as share certain services host-side so you don't add overhead to each coast instance. You can also do things like define strategies for how each service should behave after a worktree assignment change (e.g. none, hot, restart, rebuild). This helps you optimize switching worktrees so you don't have to do a whole docker-compose down and up cycle every time. We'd love to answer any questions and get your feedback!

Today, I’m talking with Todd McKinnon, who is co-founder and CEO of Okta, a platform that lets big companies manage security and identity across all the apps and services their employees use. Think of it like login management — actually, that’s a great way to think about it because the way most people encounter Okta […]
This is part of our package about Apple's 50th anniversary, read more here. It's 1989. To play a video, listen to a song, or show photos on a desktop computer requires bolting on expensive hardware, built by a different company, using different software. There are no standards, no portability, no sharing. Tyler Peppel, Apple product […]
