If with Apache you’re getting this error when deploying multiple name-based domains using port 443, or 80 for that matter

VirtualHost overlap on port 443, the first has precedence

Just edit your ports.conf (or httpd.conf)

sudo nano ports.conf

And add these,

NameVirtualHost *:80
NameVirtualHost *:443

Save and test your config again

sudo apache2ctl configtest

This should now clear ok.

from Terminal

wget https://www.dropbox.com/download?dl=packages/debian/nautilus-dropbox_0.7.1_i386.deb -o nautilus.deb

next install the debian package, and grab any dependencies needed with apt-get

sudo dpkg -i nautilus.deb
sudo apt-get -f install

You will also need python-gpgme for the daemon

sudo aptitude install python-gpgme

If needed, now install the daemon

dropbox start -i

Do this again and you’ll be given a URL to authorize your machine with an account, afterwards there will be a Dropbox directory in your Home directory syncing with your account.

Final thing linux will complain about being unable to monitor the entire dropbox hierarchy, to fix this do

echo 100000 | sudo tee /proc/sys/fs/inotify/max_user_watches

Today was time well spent building & booting the latest Chromium operating system.

Chromium OS is an open-source project that aims to build an operating system that provides a fast, simple, and more secure computing experience for people who spend most of their time on the web.

I’ve uploaded an image of the successful build, it’s taken from an 8gb stick and is available here (downloadable size 530mb).

Build Info:

Chromium OS 0.11.231.2011._03_06_1150
Chromium 11.0.691.0

You should be able to use an image writer or DD to copy the image onto a suitable stick and then boot from it.

Introduction

Download here ~ https://github.com/johnantoni/vimfiles

What you see is my own personal VIM configuration, with all manner of plugins, color formats and cool status messages.

Feel free to fork and copy it as you want, you can even drop me a line to suggest improvements.

Best,

Install Config

git clone [url] ~/.vim
ln -nfs ~/.vim/vimrc ~/.vimrc
ln -nfs ~/.vim/gvimrc ~/.gvimrc

Install Command-T

cd ~/.vim/ruby/command-t
ruby extconf.rb
make

Afterwhich you’ll be able to use Command-T (aka Textmate Goto File) with \t

Build VIM from Source

Either download from vim.org and install with Mercurial or download from my github vim mirror with:

git clone git://github.com/johnantoni/vim.git
cd vim/src

Now if you’re in linux i’d recommend install vim with ruby support via

./configure --with-features=huge --enable-rubyinterp

But if your on OSX i’d recommend installing MacVIM as it’s got ruby support baked in (plus it’s a major pain to compile vim with ruby support in osx)

./configure --with-features=huge

Whatever you decide, compile and install with

make
sudo make install

If however you want to re-configure later, run this to clean the SRC directory before re-building:

make distclean

MacVim, HomeBrew and PeepOpen

For OSX users i’d recommend installing MacVIM rather than using the Terminal client. Along with that install HomeBrew, it’s a really efficient package manager for OSX.

And if you want the GoTo file that TextMate has (and CommandT provides) install PeepOpen from PeepCode, really awesome (and support already baked into this config)

Keys

\    leader key
i    switch to insert mode
esc  switch out of insert mode

With the CommandT plugin installed you can do a TextMate go-to file with \t After which you can start typing the file your after and it’ll zero in on it

Global .gitignore

Included with this git repository is a pretty decent .gitignore file which works quite well as the basis of your global ignore file.

To install the packaged .gitignore file to your global git config, do:

git config --global core.excludesfile ~/.vim/.gitignore

NERDTree

Open with :NERDTree Create new file pressing ‘a’ Switch windows with CTRL+ww

Rebuild Help Docs

:helptags ~/.vim/doc

Create, Read, Update, Delete = CRUD

The four basic functions of any persistent storage mechanism.

Refers to all of the major functions that need to be implemented in a relational database application to consider it complete. Each letter in the acronym can be mapped to a standard SQL statement:

• Create => INSERT
• Read (Retrieve) => SELECT
• Update => UPDATE
• Delete (Destroy) => DELETE

It’s really that simple and not only applies to databases but nearly any form of application.

CRONTAB and Cron Jobs

In simplest terms, a time-based scheduling service in Unix & Linux systems.

Driven by a configuration file named crontab that specifies shell commands to run periodically on a given schedule.

E.g. * Load the LighTPD web server when the server reboots

TAR is a linux command that makes it easy to wrap up entire files & directories and put them into one file that can be moved to another location. Basically it creates a tape archive (TARBALL) of your files, allowing you to extract them later on and even compress their contents via BZIP; plus it’s really fast!

Creating a .TAR

tar -cvvf backup.tar work

…creates a tar file named work.tar which contains everything in work directory and recursively everything beyond

tar -cjvf backup.tbz work

…adding -j enables tar to compress files & directories with bzip, backing up everything in the work directory and everything beyond. note the different extension used -> .tbz denoting it’s a compressed archive

Extracting a .TAR

tar -xvvf backup.tar

…extracts / untar’s everything from the work.tar tarball inside the directory your in

Extract TarBall

if bzipped, extract with…

tar -xjvf backup.tgz

or gzipped, extract with…

tar -xcvf backup.tar.gz

Gzipped ?

GZip is essentially a free version of winzip without the you-gotta-pay-for-it stamp. Now used on it’s own it works on single files turning them into gzipped .gz files, with TAR and it allows you to gzip tons of files (see examples above).

to gzip a file do…

gzip myfile.txt

…this gzips it to myfile.gz

to extract the gzipped file do…

gunzip myfile.gz

Or Simply…

Archive & Compress directory I’m in

tar -zcvf backup.tgz . 

…Then Extract it

tar -xzvf backup.tgz
