’s Wayback Machine is a utility that caches snapshots of a given website, and provides a permanent (in as much as anything on the internet is permanent) record of a site and it’s various versions.

In the current political climate, where a page’s content can be removed by executive order, it was suggested that built in support to archive content and bookmarked pages to automatically, would be desirable.

I’ve therefore written a plugin to do just that. Have a play…

So, it’s been a little while since I’ve posted anything, but, I’m back now, so here’s a quick Emoji plugin for Known.

I wrote this plugin (which is basically a Known wrapper around jloutsenhizer’s Javascript Emoji renderer) to scratch a particular itch of mine, whereby some Bridgy backported comments from Facebook were being rendered with Unicode placeholders.

Happy Christmas!

In my earlier post on this subject, I gave a brief overview of the Known API. I hope people found this useful.

Anyway, it is the nature of development that things change, and recently I pushed a patch that fixed a couple of potential security issues. I won’t bore you with the details, except to say that this might well have an effect on how you use the API.

Sessions are destroyed after page display

In the older instance of the API, once you had authenticated, HMAC validation was short circuited and you were treated as logged in on subsequent requests (provided you remembered to store cookies). This was really a workaround to handle the way that Known would forward you to a created object after creation, and since this was a new URL, you’d need a new HMAC, but the 302 would happen before you could generate one.

Now, you are only logged in for the duration of the page visit, and sessions are destroyed after the page has been sent. Each request must now be individually signed.

Which brings us to the next big change..

No more automatic forwards

Because each page request must be individually signed, it is no longer possible to forward you automatically to the created object. It is also no longer necessary for you to configure CURL to automatically handle 302 responses.

Instead, if you’re making an API request, instead of forwarding, Known will return some JSON containing a location for your next GET request, e.g.:

This also gives room for extension.
