Code

I most­ly work in Lean and Rack­et. Like most web de­vel­op­ers, I also work with JavaScript and the var­i­ous lan­guages & tools found in the web space. (This site is made with Pollen.) Some of my Rack­et work that I’m most proud of:

• laramieRack­etpack­age—HTML5 pars­er for Rack­et
• argoRack­etpack­age—JSON Schema ad­ven­tures in Rack­et
• ri­posteRack­etpack­age—Script­ing lan­guage for JSON-backed HTTP APIs

(A com­plete list of my Rack­et work is avail­able here.)

Com­mu­ni­ty

I’m the or­ga­niz­er of Rack­et­fest, a cel­e­bra­tion of Rack­et and lan­guage-ori­ent­ed pro­gram­ming. Think of it as an rogue, unau­tho­rized coun­ter­part of the of­fi­cial Rack­et­Con.

Writ­ing

I’ve writ­ten a few books on Rack­et:

• Serv­er: Rack­et—Prac­ti­cal Web De­vel­op­ment with the Rack­et HTTP Serv­er
• Rack­et Week­end
• Lan­guage-ori­ent­ed Pro­gram­ming in Rack­et: A Cul­tur­al An­thro­pol­o­gy
