                Today I started integrating @benhencke|s MicroModSynth into .

                So far you can dynamically create synthesizers with a given number of voices and nodes and it plays the example from the GitHub repo fine on DOSBox.

                Next step: come up with a nice interface to create voices and nodes and play some notes...

                        BCC - a "barely ANSI" C compiler, but generates small binaries (64+64 com). Great if I'm making something small, like a retro implementation of something.

                        Edlin - great no frills editor that I use without irony to edit files like batch files and makefiles. I've sometimes written entire readme files in it.

                        OpenWatcom FORTRAN 77 - I sometimes write a little FORTRAN, and this goes a long way.

                                                        @vga256 I dug out the source code and put a small HTML wrapper around it to explain it.

                                                        This version of the code is the last version, dating back to October 1988. It includes buffering blocks in RAM to avoid the performance problem with writing each 128 byte block to disk, and two different ways to cheat and abort a perfectly good transfer to avoid getting charged.

                                                        38 years later I'm proud of the cleverness, but not proud of the cheating. ;-)

                                                          Ugliest and most poorly hidden #EasterEgg in #OperatingSystem history? Literally an executable - `\OS2\BITMAPS\AAAAA.EXE` - on the boot drive. CW: your eyes may bleed. Boost to people you don't like.

                                                          Don't get me wrong - I really like OS/2. But IBM never really made pretty things, did they?

                                                          And the alt text needs to be forced upon y'all in this one:

                                                          Short video clip showing a vector drawing of a green field with a road leading past some purple mountains in the background. There's a small blob of water next to the road. There are gradients everywhere: background, mountains, road, water..
                                                          The sun is orange (also gradient) with a drop shadow like only late 80s vector drawing software could. Corel Draw maybe? It reads "OS/2 Warp" in the top right corner.

                                                          There is an absurdly large metal pole with an even larger white sign full of names printed in a horribly-rendered font (probably System Proportional). The background of the sign is white and, thankfully, not gradient. I suspect this is due to technical limitation, not artistic ones.
