A couple weeks ago, I created @FISACourt, a Twitter account that automatically posts whenever the Foreign Intelligence Surveillance Court website is updated. I created it in about 5 minutes, using ChangeDetection.com and IFTTT, and blogged about how it works.
After I did that and @FISACourt got a few followers, I realized this would not be good enough. In my experience, IFTTT checks RSS feeds once an hour, and ChangeDetection’s FAQ says they check pages just once a day. That’s potentially a 25 hour delay — not so good for breaking news.
So I wrote some code to check the FISA Court myself, and set it to run every 5 minutes, using my web server (the same machine that serves this blog). You can find the code at github.com/konklone/fisa, along with instructions for setting it up yourself.
This new setup does more than check for changes and update a Twitter account — it also sends me an email and a text message so that I know an update just went out. This way, I can quickly figure out what changed and promptly add some human explanation of what the FISA Court just did [...]
