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.

Why not open the office back up on Halloween? It's be thematically cool to do so

I received a work email today, notifying everybody at the Ft. Lauderdale Office of the Corporation, that the office won't reopen until Monday, October 5TH. We were supposed to open in late June, maybe early July, but given that's it is now late July, the Powers That Be decided it might be better to just wait several more months than to continuously plan to open the office only to have to push the date back.

I can't say I'm upset at the decision.


And here I thought web bots were bad

I suppose it was only a matter of time, but the bad web robot behavior has finally reached Gemini. There's a bot out there that made 42,766 requests in the past 27 hours (so not quite one-per-second) until I got fed up with it and blocked it at the firewall. And according to my firewall, it's still trying to make requests. That tells me that whatever it is, it's running unattended. And several other people running Gemini servers have reported seeing the same client hammering their systems as well.

Now, while the requests average out to about one every two seconds, they actually come in bursts—a metric buttload pops in, a bunch fail to connect (probably because of some kernel limit) and all goes quiet for maybe half a minute before it starts up again. Had it actually limited the requests to one every two seconds (or even one per second) I probably wouldn't mind as much.

As it was though, quite a large number of the requests were malformed—it wasn't handling relative links properly, so I can only conclude it was written by the same set of geniuses that wrote the MJ12Bot.

Sigh.

On the plus side, it did reveal a small bug in the codebase, allowing some of the malformed requests to be successful when they shouldn't have been.


Well, the bugs start coming and they don't stop coming

As soon as I find one bug than I find another one.

In an unrelated program.

Sigh.

In this case, the bug was in my gopher server, or rather, the custom module for the gopher server that serves up my blog entries. Earlier this month, I rewrote parts of that module to convert HTML to text and I munged the part that serves up ancillary files like images. I found the bug as I was pulling links for the previous entry when I came across this entry from last year about the horrible job Lynx was doing converting HTML to text. In that post, I wrote what I would like to see and I decided to check how good of a job I did.

It's pretty much spot on, but I for some reason decided to view the image on that entry (via gopher), and that's when I found the bug.

The image never downloaded because the coroutine handling the request crashed, which triggered a call to assert() causing the server to stop running.

Oops.

The root cause was I forgot to prepend the storage path to the ancilliary files. And with that out of the way


No, seriously, the bugs start coming and they don't stop coming

One of the links on this entry won't work on gopher or Gemini. That's because I haven't implemented a very important feature from the web version of my blog—linking to an arbitrary portion of time! I don't even think that link will work on gopher or Gemini either, because of the way I “translate” links when generating the text from HTML.

HTML-to-text translation is hard, let's go shopping—oh, wait … I can't because of CODIV-19!

Sigh.

Update a few moments later …

Not all links break on Gemini.

Obligatory Miscellaneous

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

http://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.

It is assumed that every brand name, slogan, corporate name, symbol, design element, et cetera mentioned in these pages is a protected and/or trademarked entity, the sole property of its owner(s), and acknowledgement of this status is implied.
