  DO NOT OPEN A .ppt
EVEN FROM A BROWSER
Check the bottom of the browser screen to be sure any link that you click on is not a .ppt file; a virus and/or trojan, vundo, may spread by opening or viewing a .ppt or powerpoint file with a browser; especially, Internet Explorer may have a security hole; there are 29 other forums ;   the latest   or other removal tool can   be downloaded. ;   further collaboration: also   etc.   Also, beware of .vbs .bat .exe .pif and .scr files. Since a reinstall may be required after infected system files are deleted, a backup of your setup would be invaluable. It can be done with Norton Ghost or without. The setup of the operating system in Windows can be saved for instance in XP:
  start
   all programs
    accessories
     system tools
      system restore
       system information
        export
Heretofore, I was under the impression that the browser was in a sandbox sufficiently deep to prevent malware from accessing anything on my computer, however ActiveX components if enabled can do that. ActiveX Components in Internet Explorer can spread trojans; so, for protection, disable ActiveX in

CONNECTIVITY AND PORTABILITY
The asix presto programmer supports PIC,   Atmel AVR,   PIC16fxxx, 89S51, Atmega128 ...   .
A sourceforge compiler targets   8051, Maxim80DS390, Z80, 68HC08, and will target PIC sometime.

or can retrofit from Allen-Bradley ladder logic.

COMPILE MULTIPLE LANGUAGES ON MULTIPLE PLATFORMS
lcc and gcc are open source compilers that compile multiple languages (Fortran, C, C++, Java, Ada)
and run on Linux or Windows systems
and can target Alpha, Sparc, MIPS R3000, Intel x86 microprocessors.
There is a curve plotting language tool set, dislin, that compiles on gcc

INSURE PORTABILITY TO THE FUTURE WITH CHARACTER BASED UNAMBIGUOUS ARCHIVES
mathematical    expressions     can be output to .pdf as well as the .ps superset .dvi ,    
Also formulas can be put in illustrations with scalar vector graphics, .svg
as well as output to dislin for curve plots.     The source .TeX was   first   output in .dvi files, an extension of PostScript .ps files;
many of the of the plethera of     formats    are supported.    Many other issues  are listed.
There are shortcomings with .doc   and   .rtf   formats.
It is difficult to express mathematical expressions in html, tools exist to do it however. It can be done with open source software in a portable format that can be stored in a human editable way. Plugins with MS IE for SVG and MathML or compilers are required; however, firefox has supported SVG and MathML since 1.5. Details and links are available. There is an example of an annotated Bezier curve in a transparnet layer over Tex transformed with asciiMath and rendered with MathML.
