I’ve recently becoming interested in porting legacy PHP sites to JSPs. It seemed to me that one of the hardest parts of this problem was parsing the PHP code. Once a parse tree was created, the next step would be to emit equivalent JSP code.
I went looking for an ANTL4 grammar for PHP, but could only find an ANTLR3 grammar, so I went to work updating the ANTLR3 grammar to ANTLR4 and writing a very simple validation suite. The github project is here, and the resulting grammar is here.
I’ve been interested in RIAK for a while, and ORM’s are nothing short of fascinating.

From there, I got a little interested in online trading, but since I prefer not to have to think about trading, I started thinking about a trading bot. Part of the work I needed to do was write a…

For example, one perspective on Organizations is that they are simply representable as people, systems and the information that flows between them. Those three building blocks are, in theory, enough to…

Back in the day, Paradox was a pretty amazing database. I recently had a reason to read some Paradox files for a friend, who had a client with a Paradox database. They needed their data out of the database to insert into something more modern. Googling for the file format of a Paradox DB didn’t…
