Why is it bad style to `rescue Exception => e` in Ruby?
TL;DR: Use StandardError instead for general exception catching. When the original exception is re-raised (e.g. when rescuing to log the exception only), rescuing Exception is probably okay. Exception is the root of Ruby's exception hierarchy, so when you rescue Exception you rescue from everything, including subclasses such as SyntaxError, LoadError, and Interrupt. Rescuing Interrupt prevents the

The parseexcel-gem does not support the celltype ‘percentage’ but uses ‘float’ instead. This is not a big deal as you can also use ‘float’ to do calculations with these cells. Old .sxc OpenOffice files are currently not supported – please load these files and save it as an “OpenDocument Spreadsheet (.ods)â€. Instead of a filename the Google#new method needs the ‘key’ of a Google-Spreadsheet. This k

Build your own compiler in Ruby with LLVM
I’ve been reading and playing with VMs for a couple months now. I’ve silently created my own Ruby VM in C, running YARV bytecode. But that was an excuse to better understand the internals of Ruby, since it doesn’t have a parser, emitter and GC yet. I might blog about some of my findings later but today I want to write about another experiment I’ve been working on. LLVM is an awesome tool and I’ve
