Mysterium Calendar and Journal

1. What is Mysterium?

Megabyte - Mysterium is a calendar that can display a high range of dates, from 9999 B.C to 9999 A.D. It’s not only a calendar, but also a journal and contains an integrated image manager, Ikonikos.

2. What does it feature?

  • Its databases are reliable. Mysterium uses sqlite3, which does atomic transactions. This translates in fewer chances of database corruption.
  • Mysterium executables are self-contained. Carry them with you, anywhere, using a pendrive.
  • Cross-platform: suports both Windows (2000 / XP / Vista) and Linux (any distribution).
  • No need to install any libraries. Just click-and-run.
  • Integrated image manager: slideshow your images, preview them and backup them up in two clicks.
  • Multiple journal entries per day. Add as many entries per Day you want, and assign each of them one photo.
  • Image recycling. Do you like a certain image and would like to use it in your journal 20 times in a row? No problem! Mysterium will point to the image you want to instead of mindlessy adding it repeatly in the database, resulting in a big space saving.
  • Introductory, offline and comprehensive beginner documentation. The basic features of the interface is explained in a pdf file.

6. Bug reporting and suggestions

Feel free to email me [L7 ].


In Mysterium version 1.0, a bug will prevent image recycling. The next version will have this fixed already, but you would need to delete the database and start over. This little program fixes your database so you can add the same image to any event without deleting your database.

How to use this.

1. Download the package from [L8 ]

2. Run the according Database fix program. For Windows, it is Database fix - Windows.exe. For Linux, it is Database fix - Linux.bin. If you have TCL, you can also run the source.

3. Point it to mysterium_database.db.

4. Apply the patch and you're done. Notice that you'll need to repeat the process for as many Mysterium databases you have or whenever a Mysterium database is created with version 1.0.
