Let's Scrum

At work me and my colleague have started using Scrum. If this methodology is useful we will find out later.

Book Scrum and XP from the Trenches helped as to start Scumming. This book includes practical tips and tricks for most Scrum and XP practices. It can be downloaded for free from InfoQ website.

VsVim

I have started to use VsVim Visual Studio 2010 extension. It's vim emulation layer for Visual Studio 2010. VsVim is free and can be downloaded from here.

Scrum

Scrum is an agile approach to software development. Scrum doesn't provides complete, detailed descriptions of how everything is to be done on the project, much is left up to the software development team. This is done because the team will know best how to solve the problem they are presented. 

Scrum relies on a self-organizing, cross-functional team. The scrum team is self-organizing in that there is no overall team leader who decides which person will do which task or how a problem will be solved. Those are issues that are decided by the team as a whole. The team is cross-functional so that everyone necessary to take a feature from idea to implementation is involved.

These agile development teams are supported by two specific individuals: a scrum master and a product owner.

Scrum projects make progress in a series of sprints, which are timeboxed iterations no more than a month long.

Snippets in Vim

A snippet is a piece of often-typed text that you can insert into your document using a trigger word followed by a <Tab>. To have this functionality in my Vim I use snipMate plugin.

Vim file navigation

To navigate through directories and to open files I use NERDTree plugin. The plugin opens small buffer on the left which contains the file system tree.

If you want to pull up NERDTree so it's always visible docked to the left of your Vim window you can type:

:NERDTree

Also NERDTree allows to modify the file system tree. Hit key 'm' and it will open menu with some option.

To refresh the file system tree simple hit key 'r'.
