For software engineering, yes, at least most people will say yes. For software development, yes and no. To communicate with those software engineers who do use UML, yes. To use tools which require UML, yes. To make those pillow-thick specifications full of design diagrams as demanded by some large companies, yes. Otherwise, no.

But considering UML is just a way, albeit commonly agreed, to modeling, provided you can communicate your design to others, I see no reason to reject any usage of some variations of UML or even something totally different for representation.

I'm somewhat a software engineer. I have not formally learned UML (actually I have scratched the surface - that was when I was still in university some years ago) but over time I found myself not totally adhering to UML most of the time. Frankly I don't do diagrammatic modeling and design that much. Most of the time, I just build class interfaces as prototypes directly and then fill in the code without using any modeling tools (I don't have money to ever touch any of them). I may also choose to prototype in a language that I know best (that will most likely be some scripting language such as PHP or Perl), and then porting that design eventually to the platform I need to support (such as Java, or C[++]).

If one day you somehow get the chance to use some RAD toolts like Rational Rose, then UML will be a must because that's what it uses.

NAME
pianobooster - learn the piano just by playing a game DESCRIPTION
Piano Booster is piano teaching software that can provide piano lessons for beginners as well as for advanced players. It can be used for teaching music theory and is useful for piano practice and learning piano technique. SYNOPSIS

-d Increase the debug level -q Quick start -h, --help Display a help message -v Display the version number and exit USAGE
Piano Booster is a fun way of playing along with a musical accompaniment and at the same time learning the basics of reading musical nota- tion. The difference between playing along to a CD or a standard midi file is that Piano Booster listens and follows what you are playing on a midi piano keyboard. The program has been designed to allow you to play along on a midi piano keyboard with the scrolling notes shown on the screen. The notes you press on the keyboard appear as coloured lines on the musical stave, the colour of which depends whether you have pressed the right or wrong note. A different musical instrument sound is used for your playing depending whether you are playing the right or wrong notes. This feature also allows Piano Booster to be used with printed sheet music so you can hear if you are playing the right notes while at the same time keeping your eyes on the printed score. The music accompaniment will automatically wait for you to find and play the correct notes in the piece. Timing markers show whether you are playing ahead or behind of the beat. They appear as white crosses that are drawn over the note. FEATURES
- Piano Booster follows you when playing along to a musical accompaniment. If you stop, then so does the music. - Play a single hand and Piano Booster will play the other hand, as well as the rest of instruments, in time with you. - Change the speed of playback to match your playing ability. - Transpose +/- 12 semitones without stopping the play back. - Change the Key Signature of the piece. - Plays any standard midi or kar file. - Play along to any instrument in the midi file. - Adjust the volume of the current part or the volume your piano part. - See how accurate you're playing. - Change the start bar to start playing from any bar in the music. The repeat bars allows you to practice just a few difficult bars contin- uously. - Timing markers are white crosses that are drawn over each note and show if you are playing ahead or behind the beat. - A different instrument sound is used for the right and wrong notes that you play.
