The Boston Diaries

The ongoing saga of a programmer who doesn't live in Boston, nor does he even like Boston, but yet named his weblog/journal “The Boston Diaries.”

Go figure.

You know, we might as well just run every network service over HTTPS/2 and build another six layers on top of that to appease the OSI 7-layer burrito guys

I've seen the writing on the wall, and while for now you can configure Firefox not to use DoH, I'm not confident enough to think it will remain that way. To that end, I've finally set up my own DoH server for use at Chez Boca. It only involved setting up my own CA to generate the appropriate certificates, install my CA certificate into Firefox, configure Apache to run over HTTP/2 (THANK YOU SO VERY XXXXX­XX MUCH GOOGLE FOR SHOVING THIS HTTP/2 XXXXX­XXX DOWN OUR THROATS!—no, I'm not bitter) and write a 150 line script that just queries my own local DNS, because, you know, it's more XXXXX­XX secure or some XXXXX­XXX reason like that.


And then I had to reconfigure Firefox using the “advanced configuration page” to tweak the following:

Firefox configuration for DoH
variable value
variable value
network.trr.allow-rfc1918 true
network.trr.blacklist-duration 0
network.trr.confirmationNS skip
network.trr.custom_uri https://playground.local/cgi-bin/dns.cgi
network.trr.max-fails 15
network.trr.mode 3
network.trr.request-timeout 3000
network.trr.uri https://playground.local/cgi-bin/dns.cgi

I set network.trr.mode to “3” instead of “2” because it's coming. I know it's just coming so I might as well get ahead of the curve.

You have my permission to link freely to any entry here. Go ahead, I won't bite. I promise.

The dates are the permanent links to that day's entries (or entry, if there is only one entry). The titles are the permanent links to that entry only. The format for the links are simple: Start with the base link for this site:, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

You can also specify the entire month by leaving off the day portion. You can even select an arbitrary portion of time.

You may also note subtle shading of the links and that's intentional: the “closer” the link is (relative to the page) the “brighter” it appears. It's an experiment in using color shading to denote the distance a link is from here. If you don't notice it, don't worry; it's not all that important.
