I recently had a reason to parse a large data set, for another project. I decided that an ideal “large data set” would be my Outlook mail saved archives. Sadly, Outlook for Mac doesn’t output PST files, it outputs OLM archives, which are, essentially, giant zip files full of XML. I was coding this all in Java, so I needed a Java library to parse OLM files.
The resulting source code is here. Schema for OLM XML is here.
I’ve recently been quite interested in Graph languages, not for Graph Databases, but for representing information, in code that is essentially “things” and “relationships”. 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…
When building database ORM code, I prefer to use ebean, and I prefer to use DAO‘s. Since DAO’s are simple to make generic, I have a Generic DAO I use for all projects. I’ve finally decided to open-source my DAO code, and you can find it here https://github.com/teverett/ebean-dao.
I’ve been interested in RIAK for a while, and ORM’s are nothing short of fascinating. I decided to try writing an ORM for Riak, and the results are here: https://github.com/teverett/cbean My ORM is not an ORM of course, because RIAK is not relational. However it is ORM-like; I can store POJO’s and retrieve them. The…
I’ve tried a couple different mp3 taggers to tag my mp3 library, however, most seem to have trouble with large mp3 libraries. So, after doing some reading about AcoustID and MusicBrainz I decided to quickly code up my own tagger, MusicBrainzTagger. MusicBrainzTagger is a command-line application which recurses a directory of mp3 files and tags…
I’ve recently become very interested in blockchain, and that, naturally led me to Ethereum and Bitcoin. 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…
