After a week of practically no hosting service (so my website were completely down) I decided to move from my free hosting to another low-cost one.
For just 20$ for 2 years I will be able to not only maintain my website but to upload again all my pictures (with less quality, but it's reasonable for >5gb of pictures) So this week www.bluegod.net/fotos will be back again!

Anyway expect the unexpected, as this is a very-low-cost hosting, I hope it works most of the time!

Yet another flight...

Hi!

First of all, sorry because of my server, although my website is online and running, even my projects hosted at www.bluegod.net/something, the pictures hosted at www.bluegod.net/fotos are not online yet.
The main reason is the long size of the albums, I am trying to upload them all to Shutterfly online service, so I hope finally all the pictures will stay online at bluegod.net/fotos approximately at January.

And.. I will go to UK (again) on day 22, december!

I love Christmas, and what is better than that.. an english Christmas!

Muchísimas gracias por dejarme las Fábulas de Esopo Laura y Ana.. A pesar de que lo tendréis de vuelta tarde...

Host & Domain changes...

Hi there!

Due to my increased financial crisis after my hawaiian adventure, I have to change my domain to another cheaper domain service and also I have to move my server files because I'll finish the service with my internet provider soon, so I have to shutdown my freebsd server (238 days without a restart now), and move my webpages to a free hosting service (I hope it works), then I'll turn my BSD server into a media center mythbuntu (what a cruel destiny). Anyway expect a lot of troubles accessing my web bluegod.net and subdomains, projects... etc hosted here.

What I'll do with my pictures is move them to another place (perhaps kodak gallery, that I have to pay but just a small few, it's better than pay for my server light & internet, it was a 12MB cable conexion with R and it hosted me near 10gb of files 24/7). So Galsel will have a black future too.

In short, expect website ups & downs during this week or two.

Hawaii is near

Because of my awful academic year, limited funds and a black future approaching, I have to realize and take hard decissions. That's why I took a grant of 1650 euros just for study 3 weeks hardly and improve my english. So.. the destiny have chosen Hawaii as my destination, and cheap flights like the one from London to Honolulu (return 570 euros only) too; but spanish people, don't have any doubt that I will use your money honestly and study hard all the time I will stay there. I keep you in touch.

How to backup your filesystem without an external program!

This is a tutorial for unix systems so you can have your own backup system with just a backup script and a tar utility.

The script is based on a script made by danny (at) freebsd.org but it was heavily modified so now you can use it more easily and also it has more features.

1. What does it do?
2. What can I do with this script?
3. How to configure it
4. Download and install
5. Source code

REMEMBER to ask on this forum if you have troubles installing this script or you want help:
Backron forum

What does it do?

- Full backup every Sunday of your directories and MySQL databases
- Incremental backup every day but Sunday
- Every month all full backups are deleted but last Sunday that is renamed to a 'backup of N month' file

What can I do with this script?

- Backup a directory or directories from your computer/mount points/network to another directory or to a network mount point
- Backup MySQL Databases
- Exclude pattern to ignore a directory and its subdirectories or a pattern of files
- Backup files compressed into tar.gz format so you gain performance and disk space

How to configure it

QUOTE CONFIGURATION:

Edit it with your favourite text editor and change its options:

COMPUTER=mypc

Change it to your computers name just for name your backup files so you can distinguish backup files from another computers on the same directory.

DIRECTORIES="/usr/local/etc /etc /var/www"

Name of the directories/directory (subdirectories are always included) you want to make the backup of.

XCLUDE="" # exclude pattern "" = none

#NOTE: From 1.2Beta (included) there's a file from which patterns are read!

You can exclude a pattern of files or a directory for example "phpMyAdmin" will ignore that and its subdirectories from the backup

BACKUPDIR="/BACKUP"

The place you want to store the backup compressed files, it can point to a network mount point.

TAR=/usr/bin/tar

You need to use tar to compress and package the backup directories, you can find where it's located running a "whereis tar" on the command line.

If you want to backup your MySQL databases set this variable to 1, else set it to 0 and the script will ignore this lines.

DBBACKUP="1"

DBUSER="username"

MySQL user name that must have privileges to do a dump of all your databases!

DBPASS="password"

The password

DBPATH="/usr/local/bin/mysqldump" #path to mysqldump binary

Path to mysqldump, locate it with "whereis mysqldump"

DBOPS="-A"

Options of Mysqldump, default is backup all the databases.

QUOTE DOWNLOAD AND INSTALL:

Backron 1.2Beta
-Changes from 1.1Beta: Multiple pattern exclude. (NOT YET TESTED)
Backron 1.1Beta

Remember to make it executable! (doing a chmod 770 backron.sh as root is a good idea for security reasons, also you can make a more restrictive chmod after configure it)

After you download it you have to add a cron job line so you are sure it will run every day at a specified time

How?

Add a line like this with tabs to the end of your /etc/crontab file:
(Remember to replace (tab) using the tab key of your keyboard).

CODE:

# Backron system backup - every day 10 (tab) 6 (tab) * (tab) * (tab) * (tab) root (tab) /location/to/backron.sh

It will run every day at 6:10 AM. Change it if you want.

Backup system

I had made an script based on one from danny (at) freebsd.org to have an easy backup system of my server, but I heavily modified it throughout time so now it is able to backup MySQL and it also runs the first time without the need to modify something.

So now I share it with a GPLv2 license on this page: http://www.bluegod.net/backron

It's available on both english and spanish!

Please share the link

Note: Only tested on my FreeBSD server with BSD tar ( != gnu tar) so it can be a bit buggy, anyway it should run on all unix because of tar compatibilities (Linux, Mac OS X...)

Yet another web...

puts("Hello world!");

Instead of all blog-centrism that I don't like, I would like to make my homepage a common point to all my projects, I mean I will put a link to the websites of all the projects I was/will be involved, as you can see in the right side of this web.

Ironically I will add entries about my life just because nowadays it's hard for me to meet all of my people; in fact I can't meet any friends for a year! Also I am travelling from a site to another every year, that's another reason why I will add entries about my adventures around the world.

Also I will add entries about my interests: Programming, astronomy, nature, philosophy and music.

Maybe I could define this blog as some kind of epic-centrism-geek blog... that's an epicenter geek blog? :S ok bad joke. See u folks!
