Baby’s First Database (bb1db) Link to heading

• A pure JavaScript database I made. Sometimes it’s good to build something from scratch to learn about it
• Data is stored in Red Black trees, grammar and lexer are done using ANTLR
• Table creation and inserts all work, got bored when I started on selects /shrug

hl7x - Domain Specific Language For Hl7 Translations Link to heading

• I got the idea in my head at some point that HL7 translations would benefit from a DSL
  • Specifically HL7 v2, “pipe and hat” formatted messages
• This is a proof of concept for that HL7 translation DSL
  • Called Hl7x as “x” is often used as an abbreviation for translate
• This:
  • Defines a grammar and lexicon for the DSL using ANTRL
  • Provides a multi-pass parser (written in Java) to read in scripts and run translations
  • Initializes itself with an HL7 xml dump of all 2.x versions
    • This file is provided by HL7
• This is a library I wrote, mostly on my own time, but as it was shared with work I will not include the source code
  • I’ll include a small sample of the langugage and the ANTLR file
    • Pretty useless without the parser
  • ANTLR File
  • Language Example

Neural Net Link to heading

• A toy neural network written in Go; building from scratch to learn
• This implements a forward pass neural network
• It’s got tests, etc, but I did not add in anything to train it, so all it can do is have a random “thought” right now :)

A Little PACS (Student Research Project From Long Ago) Link to heading

• This was a pure Java Picture Archiving and Communication System (PACS) that I built for our research lab…going on memory here, I no longer have access to the source
• It included:
  • Pure Java based on J2EE design principles
  • Custom DICOM network layer
    • Run as static code to be optimized for a single processor, we optimize things differently now :)
  • Custom DICOM header parser
  • DB2 storage with xml columns for meta-data
  • Used only Implicit VR Little Endian transfer syntax (good enough for a research tool)
  • Threaded GUI in Swing
• Tested against the St. Boniface Hospital PACS and eFilm DICOM viewer successfully

PACS Performance Monitor (Student Research Project From Long Ago) Link to heading

• This is a performance monitor for PACS networks…going on memory here, I no longer have access to the source
• This tool is much like other performance monitoring tools but uses the DICOM network layer of the PACS I created to send data
• Studies of known size are sent from a network of test devices
  • These are generated using a pre-determined distribution (random intervals, set intervals, Poisson)
  • Studies are sent and data is recorded
  • The master node then compiles statistics and outputs a report
