Dependence on the PC speaker
Some computers (including mine) don't have a configured/enabled PC speaker. Consider specifically allowing any sound output device instead. --Michael Mol 07:48, 24 August 2010 (UTC)
Multiple roles
This task covers at least three things:
- File I/O
- Encoding (characters to Morse)
- Notably limited to Latin characters.
- Sound output.
At the very least, I think these separate components should be specced in the task description as being modular components, so that there is a readable boundary in code between roles. There are some other examples of such elsewhere on the wiki. --Michael Mol 07:55, 24 August 2010 (UTC)
- So let's simplify it to a direct string output. This omits the issue of File I/O, and the Python solution did that anyway. --Abu 09:46, 24 August 2010 (UTC)
- String input? --Paddy3118 13:39, 24 August 2010 (UTC)
- No, I meant indeed output, in the sense of "output a given string in Morse code". Anyway, the task itself says "Send a string ..." :) --Abu 13:51, 24 August 2010 (UTC)
- Interesting. Now it simplifies to an encoding map. --Michael Mol 14:18, 24 August 2010 (UTC)
