Goodbye peewee, hello PonyORM

Posted Wednesday, September 19 at 2:27 AM (a year ago)

For a number of reasons, I have replaced the backing ORM. Previously I was using peewee, but now I’m using PonyORM. The primary reason for this is purely ideological; I do not want to use software which is maintained by someone with a track record of toxic behavior. peewee’s maintainer responds to issues and feature requests with shouting and dismissive snark; PonyORM’s maintainer responds with helpfulness and grace. I am a strong proponent of the latter.

PonyORM’s API is also significantly more Pythonic, and rather than abusing operator overloads for clever query building purposes, it abuses Python’s AST functionality to parse actual Python expressions into SQL queries. Seriously, look at this explanation of it and tell me that isn’t just amazing.

So much for Dreamhost

Posted Friday, May 25 at 9:42 PM (2 years ago)

One of the overarching reasons I decided to build Publ the way I did was in order to take advantage of Dreamhost’s support for Passenger WSGI. I was expecting that to be the primary means of hosting my main site (which is way too big for a Heroku instance) and given how smoothly things were working with this site on Dreamhost I figured it wouldn’t be a big deal.

However, there was a huge monkey wrench thrown into things when I switched my site’s configuration over to Passenger; despite all of my configuration being exactly the same between publ.beesbuzz.biz and beesbuzz.biz, the rendition cache on beesbuzz.biz was getting its permissions set wrong, and there was some rather weird behavior with how it was making the temporary files to begin with.

In investigating this I attempted to upgrade my packages on publ.beesbuzz.biz, and all h*ck broke loose.

Dates are hard

There’s an old joke in programming, that the two hardest things to do are naming things, cache invalidation, and off-by-one errors. But this doesn’t pay sufficient respect to one of the other hardest things, namely handling date and time.

The Trouble with PHP

Posted Tuesday, May 8 at 12:00 AM (2 years ago)

I’ve had people ask me why I’m not building Publ using PHP. While much has been written on this subject from a standpoint of what’s wrong with the language (and with which I agree quite a lot!), that isn’t, to me, the core of the problem with PHP on the web.

So, I want to talk a bit about some of the more fundamental issues with PHP, which actually goes back well before PHP even existed and is intractibly linked with the way PHP applications themselves are installed and run.

(I will be glossing over a lot of details here.)
