  • Favourite Podcasts

    Over the last while I’ve been collecting wonderful podcast episodes from the hundreds of hours I’ve listened to. I’ve even workshopped some of my favourites with colleagues and friends (they all approve!).

    In Python, BytesIO is the way to store binary data in memory. Most examples you’ll see using zip files in memory is to store string data and indeed the most common example you’ll find online from the zipfile module is zipfile.writestr(file_name, "Text Data").

The reason for this is simple: for a web request or for a test case, you shouldn’t need to store any files on disk.

  • Slack Bots for Work

    In a previous post, I mentioned how I get notified of the restaurant menu via a Ruby script. Recently I’ve moved to a totally different product area and the main communication channel we use is Slack. Naturally enough, I ported the Ruby code I wrote, and it now posts the menu every day to our Slack channel.
