In this episode we are going to take a quick look at how to setup and use the NCover code coverage and analysis tool.Having the knowledge of the state of your code, is key to understanding the potential success and failures in your code. If having this knowledge is key to you, NCover is a great tool to help you better gain this knowledge

Summary In this presentation from the JVM Languages Summit 2008, Charles Nutter discusses bringing JRuby to the JVM, why Ruby is hard to implement, JIT compilation, precompilation, core Ruby implementation, Java library method access, method call semantics, scopes, open classes, heap-based frames, library challenges, strings, regexps, I/O, green threads, POSIX features, C lib support and future...

Attempts to dereference null result in an exception or a segmentation fault. Hence it is important to know those program points where this might occur and prove the others (or the entire program) safe. Nullness analysis of computer programs checks or infers non-null annotations for variables and object fields. Most nullness analyses currently use run-time checks or are simply syntactical (as in...

Summary In this RubyFringe talk, Reginald Braithwaite shows how to write Ruby that reads, writes, and rewrites Ruby. The demos include extending the Ruby language with conditional expressions, new forms of evaluation such as call-by-name and call-by-need, and more. Bio Reginald Braithwaite was the tech lead on the team that created JProbe Threadalyzer, a tool that did automatic detection of pot...

Summary In this presentation from the JVM Languages Summit 2008, Cliff Click discusses how to optimize generated bytecode for running on the JVM. Click analyzes and reports on Java, Scala, Clojure, JRuby, JPC and JavaScript/Rhino and points out several places where each of them could increase their performance such as elimination of FixNums, escape analysis and best practices for testing byteco...

Summary Creating secure code requires more than just good intentions. Programmers need to know how to make their code safe in an almost infinite number of scenarios and configurations. Static source code analysis can uncover the kinds of errors that lead directly to vulnerabilities and in this talk, Brian Chess frames the software security problem and shows how static analysis is part of the so...

Summary Google Web Toolkit (GWT) tech lead Bruce Johnson discusses the design of GWT, how GWT converts Java into JavaScript, community involvement with GWT, new features in GWT 1.4, and the philosophy behind GWT. Bio Bruce Johnson is a Google Software Engineer and tech lead of the Google Web Toolkit (GWT). Prior to joining Google, Bruce cut his product teeth as lead developer of AppForge's Mobi...

Normally I would have gone through this many times already, however I have the good fortune of all your comments :). Even so, it's always a good idea to take a timeout and make sure you're not going off the deep end. In this episode I do a code review with Ayende and Steve Harman and have a really nice AHA! moment. by Rob Conery
