Setting the T-Rex Replica's Delay Tempo

read in 3 min

Intro I was doing some tracking with a guitarist in my home studio the other day and we were laying down some overdubs using the T-Rex Replica delay pedal. He wanted to sync the tempo to a subdivision of the songs BPM, but had to do this manually. I noticed a MIDI in port on the side of the pedal, and thought surely there must be a way to set the tempo programatically.

Sentities Overview: Twitter->CoreNLP & Async Clojure

read in 5 min

Introduction Sentities is a Clojure project that connects to Twitter’s public and free streaming API and pulls the random-sample tweet stream. CoreNLP is applied to obtain the named entities and a sentiment score via my damionjunk.nlp Clojure library. There isn’t anything fancy going on here. The aim of this blog post, and the Sentities project is give a flavor for how one could go about doing these sorts of tasks with Clojure.

TL;DR Download my QSL card template, replace my info with yours, and send to printers. You’re QSL-card-good-to-go. Problem I recently went through the process of creating my own QSL card backs using Adobe’s InDesign, and printing “small” quantities using the 4x6 postcards at OvernightPrints.com. I have no affiliation with overnight prints, they just had an easy to use web interface and clear measurements for the postcard bleed / safe requirements. For some reason, I was unable to find any pre-existing high resolution QSL card back templates that were downloadable and customizable.

AWS, Immutant, Torquebox, and Clustering - Part 1

read in 6 min

note: these writeups assume you’ve got a working Clojure/JVM environment, know how to use the basics of AWS (ec2, AMI, S3), and have played with single-node Immutant Amazon Web Services + Immutant and Torquebox Immutant and Torquebox are completely awesome, as is the community support and responsiveness on the Freenode IRC channel #immutant. After lots of feedback, suggestions, and help, it seemed like it would be worthwhile to document the setup procedure for this stack running clustered on AWS.
