This kind of brute-forcing is common. The simplest way to deal with it is to set up SSH public key authentication, disable SSH password authentication, and forget about it.

The State of Ruby VMs — Ruby Renaissance 89

Posted by Soulskill on Sunday November 22, 2009 @11:59AM from the take-your-pick dept.

igrigorik writes "In the short span of just a couple of years, the Ruby VM space has evolved to more than just a handful of choices: MRI, JRuby, IronRuby, MacRuby, Rubinius, MagLev, REE and BlueRuby. Four of these VMs will hit 1.0 status in the upcoming year and will open up entirely new possibilities for the language — Mac apps via MacRuby, Ruby in the browser via Silverlight, object persistence via Smalltalk VM, and so forth. This article takes a detailed look at the past year, the progress of each project, and where the community is heading. It's an exciting time to be a Rubyist."

Comment Source code: sloppy or clean? (Score 1) 167

One method I use to assess software quality is to skim through the source code. If the source is clean, organized, elegant, and well thought out, I have greater confidence. If the source is sloppy, uses inconsistent indentation/spacing, and is generally a mess, then it's obvious the author(s) lacked attention to detail and didn't put much care into it.

This doesn't fully answer the question—notably, clean-looking code can still contain bugs—but it can yield surprising insight in a short time.

After all, security is part of correctness, which in turn is part of building software with ability and care.
