DeMicrosoft Your Life
How are you?
In this list I bring you a variety of alternative software to those from Microsoft, and also that these free and open source programs
So enjoy this list!
(I will be updating it every day)

AI Slopfree Software Catalog
A more optimistic homage to the slopware catalog https://alternativeto.net/lists/44427/slopware/, this list is designed to showcase projects, both FOSS and proprietary, which reject contributions from Generative AI LLM slop machines. The most pessimistic thing about this list is how short it is and how so many commonly used software solutions and websites are not included.
I have to give it up to the following sites for providing references:
https://codeberg.org/brib/slopfree-software-index
https://github.com/melissawm/open-source-ai-contribution-policies
There are a lot more projects on this list which I didn't include because they aren't on AlternativeTo (yet). I'll be adding more entries to this site (and removing those who fold to the AI overlords) on a regular basis. I'm including references, which are all first-hand declarations from the development teams for each entry to ensure items aren't included based on hearsay or conjecture.

QEMU (manager) is the only solution against EGPFault in Win87EM.dll with newer Intel-CPUs
QEMU Manager is the very good Windows GUI for QEMU. In difference to VirtualBox or VMware Player you can emulate several CPUs, which is necessary for old 16bit applications with EGPFault in Win87EM.dll with newer Intel-CPUs (from 2013 and later) in all other virtual machines except QEMU.
So only with QEMU (not with VMware or VirtualBox or Windows XP Mode) you can use and compile Delphi 1.6 programs, when you have a newer Host-CPU from Intel. Without QEMU you must buy another computer with an AMD-CPU, because VirtualBox or VMware Player cannot emulate various CPUs, as QEMU can.
Details see:
This together with AQEMU (for GUI) works as well as VirtualBox and VMware on my Linux system.
The website for QEMU says to install via the Homebrew or MacPorts package managers. I haven't used either of these. Is it possible to install without a package manager?
https://www.qemu.org/download/
İts good but only linux and mac officially supported (there is no executable file for windows but some 3.rd party person compile for windows) additionally GUI does not exist soo long learning curve exist because you need to learn QEMU parameters. Not user friendly.
GPU acceleration with VirGL.

Strengths:
• Drop-in replacement for VirtualBox. Assuming for the most frequently use features of VirtualBox. • Easy to use Graphical User Interface (GUI). Multiple GUI to choose from at https://wiki.qemu.org/Links#GUIs_and_management_tools.2Fsystems • Open source. If you are not familiar with "open source", it means this software is more secure. Because its code is publicly available for review and contributions at https://www.qemu.org/contribute • Attractive GNU General Public License version 2. This means the software code of this extension is owned and supported by a friendly not-for-profit community. Instead of a for-profit corporation. https://metadata.ftp-master.debian.org/changelogs//main/q/qemu/qemu_5.0-14~bpo10+1_copyright • QEMU is a member of Software Freedom Conservancy. Which is a not-for-profit organization that provides legal and administrative assistance to open source projects. https://sfconservancy.org/projects/current/ • Large & friendly community of contributors • Emulate Linux, macOS, Microsoft Windows, UNIX, and other platforms • Fast. Often faster than VirtualBox. • Full-system emulation • Support a wide range of disk image formats. Such as, but not limited to, .dmg, .img, .iso, .vdi, .vmdk • QEMU can save and restore the state of the virtual machine with all programs running. • Guest operating systems do not need patching in order to run inside QEMU. • Access a directory on the host filesystem from the guest using virtiofsd • Available on Debian 10 Buster. With an optional Backport. So that you get the most recent version of QEMU at https://packages.debian.org/buster-backports/qemu • QEMU can also do emulation for user-level processes, allowing applications compiled for one architecture to run on another.
Challenges:
• Documentation is available on the web. But for newcomers it is limited, hard to find, and navigate. Any volunteer to contribute to improving QEMU documentation? Find https://wiki.qemu.org or https://www.qemu.org/contribute/ Alternatively, after installing QEMU, some documentation are available within QEMU
Using:
• QEMU: version 5 • Host: Debian 10 Buster
the best virtual machine I ever used for its performance and speed, unlike other VMs QEMU made it easier all you have to do is to bring the ISO and run it directly without any configuration, because yes it uses the real hardware you have, enjoy your distributions with your real speed.
