Re: Company sued over comments in code 26 years, 3 months

Pete Ware

With any luck, the company will be bankrupted by the lawsuit. Of course, judging by the meaningful variable names (watermellon?) and the fact that they don't even know who wrote the code (great bug tracking and regression testing going on there -- not) they wouldn't be in business to long anyway. Actually, ignoring that I'm just a bleeding heart liberal, as a programmer I find the code really offensive. --pete

Hear, hear! I agree wholeheartedly. BTW, it's called NAS, not netaudio these days due to some conflict with Townsend Computers who has a netaudio product. Ray

[Success+Problem] "Finnish Landrace" `sparc-sun-solaris2.6' 26 years, 3 months

Christoph Wedler

Building was fine. Having the toolbar on the left side is still a problem (frame resizing, workaround in XEmacs-20.4 doesn't work with XEmacs-21.0). The placement should be probably be able to set with ~/.Xresources. Sometimes (well, I guess if all 256 colors are used), I get some strange lines in my shell where I've invoked XEmacs from: 118> allocate_nearest_color returned 0!!! Warning: Cannot allocate colormap entry for "Maroon" allocate_nearest_color returned 0!!! Warning: Cannot allocate colormap entry for "ForestGreen" allocate_nearest_color returned 0!!!
