nik4nix

Main idea here is that you can use Nik Plugins stand-alone without officially supported 3rd party host application (Lightroom, Photoshop, Spark, Portfolio). On Windows or Linux. Source code can be compiled natively for Linux or for Windows with Lazarus IDE. The program is dedicated to Ubuntu users, where you can install Nik Collection using wine. On Ubuntu you can either use native Linux version, or native Windows version running via wine. In fact, currently the latter is recommended, because there are some UI glitches related to gtk widgetset if you compile for Linux - the UI looks better in native Windows version (this can be fixed in the future). Even if you use native Windows version on Linux via wine, the app will be aware of wine and will still be integrated with your Ubuntu desktop and will be integrated with supported apps on it, like Gimp, Pinta, Darktable, Nautilus, etc. It will still talk to your shell, and provide all the integration with your Linux.

Multi Icon

Create stunning, high quality (256 x 256) multi-resolution icons (.ico) and "mainicon" resources (.res) with ease and reliability. Open an image from file, or paste one in with transparency, or drag and drop an image directly onto the corresponding icon resolutions, then save. The multi-resolution icon stores a 256 x 256 image in PNG format, and five images at 64 x 64, 48 x 48, 32 x 32, 24 x 24 and 16 x 16 in native Windows icon format for maximum compatibility, back to Windows 95. Use a single Master image for the complete set of images, or separately individualise each image resolution for complete control over appearance. Support for 32 bit images with 8 bit alpha mask, and built-in common mask shapes to instantly transform a basic, square image into an alpha-transparent shape with one click. Save as a multi-resolution icon in either the standard Windows icon (.ico) format, or as a Windows resource (.res) in the "mainicon" format.

transmission-daemon-cygwin

Feb. 7, 2019 Transmission is a respected Fast, Easy, and Free BitTorrent Client, as from their site https://transmissionbt.com/about Unofficial Windows build runs perfect either Windows service or daemon. 32 bit and 64 bit versions. 32 (runs everywhere), 64 only 64-bit Windows. Decision made to maintain choice 2.7x core rather than somewhat buggy 2.8x-2.9x cores. That's why you will see infrequent and less bug fixes than official branches. All the features of 2.8x-2.9x (except rename). Run this solid 2.77+ port for extended days, it doesn't crash or lock. Prime for seedbox use. The included remote GUI port is fine tuned to the daemon released here. Temporary piece support. https://trac.transmissionbt.com/ticket/532 plus many featured enhancements! Tested, stable enhancements users requested. Specifically modified and bug tested for Linux GCC and Windows (cygwin gcc/g++) compilers. Current release 14734-18 020619 https://github.com/cfpp2p/transmission/releases
