To stopping top-posting

by ao2, February 26, 2010

I am still fighting my little personal battle against mindless-forwarding in chain-letters (I call that Wild-CC) and top-posting in e-mails.

Today I've had another confirmation (as if I needed any) that top-posting is a bad way to reply to a message.

Added a howto about using your (Drupal) site as an OpenID over SSL, on the wiki.

Starting by now http://ao2.it is also my OpenID.

As I am running my own Identity server, if you trust me more than others, and need an OpenID provider —and I know you—: try asking me.

Branding patches with git and vim

In linux kernel development there are informal, and yet quite solid, conventions which apply when sharing patches and collaborating during the —public and undisclosed— phase of code peer-review.

As some of you may know, all the communications about kernel development happen via e-mail, and there are some tools to ease the task of preparing and sending patches; these tools allow some degree of customization, or “branding” like I am calling it in this case.
