New release of Costa – version 1.2.0

Once again I have released a new version of my MS-DOS based graphical shell, Costa.

The main feature in this new version is support for multiple profiles. It is now possible for several users to use the same installation of Costa, each with their own settings, theme and personal desktop. One user could also have separate profiles for work, play etc.

New release of Costa – version 1.1.0

Yesterday I released a new version of my long-time hobby coding project, the MS-DOS based graphical shell Costa.

There’s not much new to see. I added a “Tip of the Day” dialog, and some new icons for you to choose from when creating desktop links, but mostly it’s all about bugfixes and improved stability.

For those who are interested in development, visti GitHub to have a look at the source code. It’s not the most fancy codebase, as it has been coded on-and-off over the past decade, but it’s stable and fairly compact.

In support of Open Source

Over the past couple of years I have been using Open Source software increasingly. More and more of the applications I use everyday have been replaced by open source alternatives, and I now only have a handful of proprietary software left. Even my operating system has been replaced by Ubuntu Gnome.

Since I am using so much open source software, I figured I would live up to this ideal by releasing the source code to one of my own pieces of software, The Costa GUI.

As of September 2017, the full source code is available on Github:

This also fulfills a long overdue promise I made several years ago on my old GUI related website, where I declared that the code would be available once version 1.0 was released.

For more information on Costa, head over to the dedicated website.

The Costa GUI

A hobby coding project of mine, Costa is a program which runs on top of MS-DOS or compatible operating systems. The aim of it is to replace the DOS-prompt with a clean, user-friendly interface – a so called GUI (Graphical User Interface). Costa comes with full mouse and keyboard support, and a bunch of useful accessories.

Most development took place between 2004 and 2012, when version 1.0 was released. Since then I have moved on to other projects, and now rarely fire up the code editor to work on Costa.

Costa has it’s own homepage, where you can learn more and download the program free of charge.
