NoteBook FanControl (NBFC)
Cross-platform fan control service for notebooks
NoteBook FanControl (NBFC) is a cross-platform fan control service for notebooks. It comes with a powerful configuration system, which allows to adjust it to many different notebook models. Currently, there are no pre-built releases for Linux, but you can easily build NBFC yourself. In general the NBFC Wiki is the first place to go if you have any questions. If you want to build NBFC from source, the first thing you have to do is to download the source code. You can easily clone the NBFC repository via git. Make sure the Mono runtime + development tools are installed on your machine (Debian based distros: mono-complete, Arch based distros: mono). Config files are an integral part of NBFC, because they define how NBFC interacts with your notebook's embedded controller (EC). The EC monitors your system's temperatures and controls the fan(s). It sits on the motherboard or is integrated into a Super I/O chip & is connected to the Southbridge via the Low Pin Count (LPC) bus. -

The interface aims for simplicity: it stays out of the way when not needed, only intercepting input when window actions are explicitly triggered, so it doesn’t disrupt regular typing or focus. Winslop also supports multi-monitor configurations, enabling users to manage windows across screens with consistent behavior and predictable layouts. -

OpenTabletDriver
Open source, cross-platform, user-mode tablet driver
OpenTabletDriver is an open-source, cross-platform, user mode tablet driver. The goal of OpenTabletDriver is to be cross-platform as possible with the highest compatibility in an easily configurable graphical user interface. OpenTabletDriver functions as two separate processes that interact with each other seamlessly. The active program that does all of the tablet data handling is OpenTabletDriver.Daemon. The daemon must be started in order for anything to work, however, the GUI is unnecessary. If you have existing settings, they should apply when the daemon starts. The requirements to build OpenTabletDriver are consistent across all platforms. Running OpenTabletDriver on each platform requires different dependencies. Run build.ps1 to produce binary builds to 'bin' folder. These builds will run in portable mode by default. -

QuickLook
Bring macOS “Quick Look” feature to Windows
Bring macOS “Quick Look” feature to Windows. One of the few features I missed from macOS is Quick Look. It allows users to peek into a file's content at lightning speed by just pressing the Space key. Windows, on the other hand, does not have this handy feature, until now! I am aware that several alternatives are already available on the Internet (e.g. WinQuickLook and Seer). Despite these options, I still decided to craft another one by myself, because they are either not being actively developed, lack variety, or ask for some. Tons of supported file types. Fluent design. Touchscreen friendly. HiDPI support. Preview from the open and save file dialog. Preview from 3rd-party file managers. Easily extended by plugins. Strict GPL license to keep it free forever. Preview next file by clicking on it or using arrow-keys (arrow-keys move selection in the background if the preview window is not in focus). -
