About The Author

My name is Jonhnny Weslley. At the time of writing I’m twenty-three. I’ve lived in Campina Grande, Brazil, since 2008. Previously, I lived for most of my life in Caxias, Brazil.

Research

I am M.Sc. candidate in the Federal University of Campina Grande, Brazil, working as research assistant with Francisco Brasileiro in the Distributed Systems Laboratory. My current research concentrates on the design and implementation of the distributed file system BeeFS which focuses on the specific setting of corporate desktop networks, while remaining flexible to add easily new machines to a running system. Previously, I have focused on challenges in implementation of Nodewiz's improvements. Nodewiz is a scalable peer-to-peer and fault-tolerant resource and service discovery for overlay networks and grids that supports multi-attribute and range queries.

My research interests include parallel programming, MapReduce, distributed data storage and distributed file systems.

Feel free to contact me.

Scala Shell

Scala Shell (scalash) is a shell for programming in Scala. Scalash is run from the command line and allows the programmer to experiment with code in real time. It allows you to enter Scala commands at the prompt and have the interpreter respond immediately.
A quick summary of the features present:

  • colourized output (highlighting)
  • auto-completion, aka Tab-completion
  • start script support - when an interactive shell is started, Scala Shell reads and executes commands from ~/.scalarc, if that file exists.
  • persistent history (~/.scala_history)
  • command history
  • command load




You can install the current release directly with Scala Bazaar:

sbaz update
sbaz install scalashell-scala

Scala API lookup with Ubiquity

A quickly hacked up Scala API lookup for Ubiquity, the first prototype of a natural language web service connector created by Mozilla Labs. It basically prepends a google search with the site: parameter pointing to the Scala API. Click here to install it.
