SAPO en

The SAPO system history

SAPO is a set of powerful applications oriented to the CARTA 's implementation (transform artistic creation to technical drawing), designs blond curtains, lace , etc. ... These products are manufactured by the German company Karl Mayer 's textile machinery or in ancient looms leavers.
The SAPO system was originally created for HP's workstations with HP-UX operating system, because they were more powerful than any PC on the market. The personal computing progress make PC getting faster and cheaper, and became more interesting to migrate the code to the new and primitive Linux running on personal computers.

We choose Redhat distribution because was free and had a lot of similarities with directories and config files structure with HP-UX. Redhat became a commercial product, so we move to another open source alternative to maintain and improve the stability and security. This distribution isCentOS, which did not have the latest versions of software that other distributions derived from Redhat have like Fedora, but instead have a better stability .

We kept the maximum appearance with the idea to ​​avoid user adaptation to different environments that haven't used. For this reason, we install a linux compatible HP-UX workstations desktop called CDE, but now we are working to migrate SAPO system to any modern desktops integrated with current Linux versions like Gnome, or KDE, to improve the user experience and comfort as much as possible without losing security and stability.

SAPO system installation's notes

• Currently is needed to install SAPO on PCs, laptops and desktops, where you can install a CentOS Linux operating system. The recommended version up to date is CentOS 5.x, because the old CDE desktop is incompatible with the latest version (CentOS 6 when writing this manual).
• During the operating system installation, hard drive's data could be erased so you should have a backup of your existing user data.
• The setup editor used in this manual is vi. This file editor is very powerful, but not recommended if you don't have previous experience. In this case, there are other editors more intuitive like nano'.
• Remember that edit config files is critical and extremely delicate operation that can make the system won't boot properly.
• A new system installation have 4 stages:

1. Installing the Linux operating system 'CentOS 5.x'.
2. Installing the CDE desktop.
3. Installing the SAPO design system.
4. Installing additional applications.
