Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci

Calendar App To Perform Date-Time Related Functions
Github - https://github.com/shivammathur/C-CPP-Calendar C-CPP Calendar app is a easy to use app to do all the functions that a calendar is used for. The app is very handy and extremely better than using a physical calendar. It is available as both x86 and a x64 versions. The app can display day of any date in the Gregorian calendar (1753 - 9999). It can be used to display calendar of a month of a year. The most awesome feature is that it displays the calendar of a year in a well formatted layout like a paper calendar and also generate a text file for the same. It is very handy when it displays the dates in a month on which a day occurs in that month. C-CPP Calendar provides personalized user account with password protection (MD5 based). C-CPP Calendar is compatible with Windows 2000 up-to Windows 10. Though no official support is there for Linux or mac, it was tested to be work
GridLAB-D is a new power system simulation tool that provides valuable information to users who design and operate electric power transmission and distribution systems, and to utilities that wish to take advantage of the latest smart grid technology. It incorporates advanced modeling techniques with high-performance algorithms to deliver the latest in end-use load modeling technology integrated with three-phase unbalanced power flow, and retail market systems. Historically, the inability to effectively model and evaluate smart grid technologies has been a barrier to adoption; GridLAB-D is designed to address this problem. User documentation can be found at: http://gridlab-d.shoutwiki.com/wiki/Quick_links The source code is available from GitHub. See https://github.com/gridlab-d/gridlab-d. Issue tracking is handled by GitHub. See https://github.com/gridlab-d/gridlab-d/issues.
