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.

It's probably a good thing some malformed URLs are considered “valid”

It seems it's all too easy to generate double slashes in the path component of a URL, because I received via email a report that my current feed files all had that issue.

Sigh.

I made a change a few months ago in how I internally store the base URL of my blog. It used to be that I did not store the trailing slash (so that "https://boston.conman.org/" would be stored as "https://bost.conman.org") so I had code to keep adding it back in when generating links. I changed the code to store the tailing slash, but missed one section of code because I don't subscribe to any of my feed files and didn't notice the issue.

I also fixed an actual crashing bug. All I have to say about that is that web robots are quite good at generating really garbage requests using a variety of methods—it's like free fuzz testing! Woo hoo! Sob!

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: https://boston.conman.org/, then add the date you are interested in, say 2000/08/01, so that would make the final URL:

https://boston.conman.org/2000/08/01

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.
