There are three ways to get the latest updates.
Note: The Subscribers feature in Ghost is in beta and doesn't support automatic emails on new posts. For now I send a manual email whenever I write a significant post (500+ words or so).
2. RSS Feed
You can follow the RSS feed which includes every post on Feedly or any other RSS reader.
You can also follow the feed for a specific tag, by substituting
foo with the tag's name:
For example, Python posts are at: http://blog.tedmiston.com/tag/python/rss/
Additionally, Python posts are aggregated into Planet Python, which I recommend subscribing to for any developer using the language.
3. Push Notifications
To receive push notifications for new posts, I recommend the app Boxcar for iOS. Once you have downloaded it, open the link below on your iOS device.
