Geraldo spotted that "Nagy Daniel has opensourced aefdisk that has many features: - Creating all types of partitions, with absolute or relative size - Deleting partitions based on their type or place in the table - Formatting FAT partitions quickly - Hiding and unhiding FAT, NTFS/HPFS partitions - Changing a partition's type ID - Activating a partition - Installing standard loader code in the Master Boot Record - Displaying partition information - Displaying logical characteristics information - Completely command line driven - Automatic calculation of free space and available partition entry - Handling as many harddisks as your hardware and BIOS supports - Support for max 8 GB harddisk without Extended BIOS - Support for max 2 TB harddisks if Extended BIOS is present. And masterbooter that seems to used in pair with aefdisk." Requires Borland C/TASM.

Robert Riebisch let us know that Chris Kirmse recently open-sourced his popular directory lister ZDir from the early 1990s. ZDir is now under the GNU GPL v3. The ZDir home page is still at tipovers, but you can get the source from ZDir Github. Source code is for A86, but you need version 3.22 to build out of the box. Source code for ZDirCfg (to configure colors and other behavior) is currently not included, but a binary is included in zdir21.zip.

Gene Buckle writes: "On October 26th, 2018 I purchased the software assets of Full Moon Software. Full Moon Software used to be known as Crescent Software. They produced a line of excellent development libraries for MS-DOS. The supported environments were QuickBASIC 4.x, Microsoft Professional Development System v7.x, and Visual Basic for DOS. The idea behind obtaining these products was to release them to the public domain to ensure that people could still access these things in the future. While most developers will have no use for these products in a modern develoment environment, they still have value as an example of "how it was done" back in the heyday of x86 DOS development. The software in this repository hasn't been modified from how I received it from Ethan Winer, the original author. While all the source files carry some kind of Copyright notice, the software is now in the public domain." The home page for Full Moon Software can be found here. Gene's archive is at Crescent Software Archive.

Gene has posted a huge trove of classic PC software. "This area contains various file collection CD-ROMs from the late 80's and 90's as well as archives of popular, but no longer active public FTP sites." You can browse within each CD-ROM for specific files, or download an entire CD-ROM image. Find it at Retro Archive.

Lzip is a lossless data compressor with a user interface similar to the one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip -0), or compress most files more than bzip2 (lzip -9). Binaries, user manuals in ASCII format, and fully configured sources plus some simple instructions on how to rebuild are available at DOS lzip.
