Easily Start and Stop Docker Compose Projects with Captain

Jens Segers has created a handy shell script to easily start/stop Docker Compose based projects:

Captain searches for docker-compose projects in your $HOME folder and allows you to start and stop those projects by passing a part of the parent directory name.

Let this small recording of Captain in action convince you:

JavaScript Object and Array Explorers

If you’re starting out with object and array manipulations in JavaScript these handy tools by Sarah Drasner might come in handy. The reason they work so well is that it’s one page, and it’s driven by natural language.

Do not however that the yielded code mutate the original arrays/objects (thus aren’t immutable) … I feel a PR coming up 😉

Keynote Extractor


Great tool by the folks at Mono. Just a drag a presention made in Keynote on the app and it’ll generate a neat HTML output containing both your slides and presenter notes.

We thought the default HTML export in Keynote didn’t fit our needs. Extract your slides alongside your notes using our super easy drag ‘n drop application for macOS.

Works great. It’d be handy if the generated images were resized though, as the end result can become quite large.

Be sure to read the introductory blogpost too, as it’ll give you some more background and highlight why the app can not be found on the App Store.

HTTPie – Command line HTTP client


HTTPie (pronounced aych-tee-tee-pie) is a command line HTTP client. Its goal is to make CLI interaction with web services as human-friendly as possible. It provides a simple http command that allows for sending arbitrary HTTP requests using a simple and natural syntax, and displays colorized output. HTTPie can be used for testing, debugging, and generally interacting with HTTP servers.
