It's hard to describe how cool this new release is. :-) If you have not done so already, please make sure to go to the new ChezWEB landing page:

While this may not come as a surprise for some of you who are well versed in the command line world, but I was just recently informed that the mailx mail program, which is often the default program linked to mail(1) in many Linux systems, including my personal favorite, Slackware, actually supports IMAP! Not only does it support IMAP, but for my uses, it supports it rather well. Amazingly enough, it also supports a host of other interesting things, and this means that I am now happily enjoying using mailx as my main mail client. This probably will not last long, as I rarely stick for too long to a single mail program, but for the moment, it's really neat to be able to add this little program, elegant in its simplicity, to my ring of mail clients to use and rotate.

People often think that adding more lines of code is the same thing as making progress on a project. I often find the opposite to be true. On my recent research for example, reducing the size of an implementation and improving its performance at the same time is a lot better than having this massive program.
Let's all remember the pursuit of simplicity and elegance in our solutions, while we pursue the latest and greatest features.

It is a sad day. I really like the Monotone VCS. I like it more than the others I have used. Yet, today I believe I take a different path. Monotone has served me well, but I can fight the unwavering popularity of Git no longer. I simply fail to have enough justification to use Monotone over Git now, despite my personal preference: simply put, I want to make it easier for others to work on my code.
Farewell, Monotone, and begrudge me not my betrayal of thee for greener pastures.
