posted by

Preamble As I wrote a few weeks ago, I am currently developing an open-souce ithare::obf library. And apparently, to make sure it works more or less consistently, a Damn Lot(tm) of randomized testing (and preferably under different compilers) is necessary. As a result, last week I found myself in a search for a cheap Linux box […]
