Miscellaneous

I am discussing here some points that may be of interest to beginners in Tcl/tk. Please check this  guide .
If you have some questions to be answered, send to my    address, and I'll answer it here when time allows.
If you are unsecure of how to do some simple commands (well, not so simple sometimes), you can look on  how do I do.

Brazilian keyboard

If you write in portuguese (BTW, I'm brazilian), perhaps you find useful my  brazil.tar.gz  file. Put it in your
/usr/lib/kbd/keytables/ directory and change your rc.local to load it with loadkeys.  To key in accented characteres, you may type the accent with AltGr and then the vowel, or use directly AltGR + {a,s,d,f,e,r,u,i,o,p,l, and c} to see the shortcuts I've done. (I only use this last, faster way)

Some hardware projects

If you want to do something with hardware, specially microcontrollers, I would recommand you Microchip's PIC series. They are small things but very powerfull. I have submitted some projects of mine to  Picpoint.

Editing html

When I made the migration from Msdos to Linux, I used to work with wordstar-like text editors, so I found a very natural replacement with joe. Later, I discovered VIM (Vi IMproved), a really terrific text editor for all our programming tasks. I plan to write some notes about it later, but don't hold your breath! Find by yourself why I have dismissed Amaya, as my html editor.

Later I have discovered wpp (see links), a preprocessor for html files with macro capability. Combined with Vim this makes a very productive environment for maintaining a web site with several similar pages like this one.

I try to make this site compliant with html-4.0 and CSS, using the W3C validation services. This is impossible when writing with Frontpage(TM), Communicator(TM) and other commercial html editors. (try to validate your site if you don't trust me) If you don't feel comfortable with text editors like Vim, I suggest you try Amaya. It generates good html-4.0 code and it's fully visual and structured.
