Era of the Mega, Giga and Tera

In the 80’s we had megahertz speed processors, megabyte sized disks, and kilobit speed wans with megabit lans.

In the 90’s we still had megahertz processors, but gigabyte sized disks, megabit wans and 100 megabit lans. wireless was megabit.

Here we are in the 2000’s and we have gigahertz processors and soon, terabyte sized disks. On the wan side we are in the multiples of megabits still but lans are gigabit. wireless may reach the gigabit with UWB.

We may never have terahertz processor cores.

What will he do with terabyte disks and terabit lans?

VIM rc file stuff

vim

To be honest, I prefer a good GUI IDE for development projects. MSVC 6 with Visual Assist X rocks for C++. For the Rails development I do on my windows laptop, however, I just use a combination of Scite, standard Windows explorer, and a cmd window. It isn’t Textmate, but it isn’t bad either. I’ve tried Eclipse, but it usually lets me down. It is confusing to install. It can be confusing to import an existing project. It may not even do what I need. It is too complex to configure. It is also quite large (ie. slow). If it had a new killer feature, I might reconsider it in the future.

Occasionally, though, I need to work on the Unix box that has our code. This means that I need a decent editor under Unix. This means Vim.

Vim is really good at dealing with all the different file types out there and providing support for syntax highlighting as well as proper indentation and completion. Recently, I had to create a .vimrc file in order to edit some code and get the spacing properly set.

Here are some good links for that:

A great page on using VIM for Ruby and Ruby on Rails. Interesting sections on using VIM as and IDE (relevant for other languages as well) http://wiki.rubyonrails.org/rails/pages/HowtoUseVimWithRails

A nice small blog post on a vimrc http://www.quotedprintable.com/articles/2005/11/24/vimrc

A nice complicated example http://www.hermann-uwe.de/files/vimrc

When I setup my vimrc, I always turn off tabs for everything except makefiles. The vimrc is expressive enough to handle conditionals based on the file type involved. For example, here is one of my .vimrc files (I have several similar files on various accounts). Notice how it is setup for Python, but was easy to pull off the necessary differentiation just for ruby.

set nocompatible " We're running Vim, not Vi! syntax on " Enable syntax highlighting filetype on " Enable filetype detection filetype indent on " Enable filetype-specific indenting filetype plugin on " Enable filetype-specific plugins

set tabstop=4 ” tabs are 4 spaces! set shiftwidth=4 ” tabs are 4 spaces! set expandtab

set pastetoggle=

au BufNewFile,BufRead Makefile set noexpandtab au BufNewFile,BufRead makefile set noexpandtab

colorscheme elflord

augroup ruby autocmd BufReadPre,FileReadPre *.rb set tabstop=2 autocmd BufReadPre,FileReadPre *.rb set shiftwidth=2 augroup end

Hip Tip for Windows

When you want to get rid of a lot of startup crap that gets installed on a computer, just do:

start msconfig

It gives you a gui to change all the settings.
