Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

RSS and ATOM are just a way to format an XML file that can be downloaded from a server. There is nothing special about it otherwise and it is strictly one way as its just downloading a file.
One important thing if you are building a RSS application is that the server should support conditional requests (the
If-Modified-Sinceheader). This way, a client does not have to download the entire feed on every update. It simply sends the last update date with its request and the server returns an empty response if the feed is up to date.There are some applications (for example YouTube) which dont support this, resulting in higher-than-necessery data usage, especially on mobile.
