DIY project to build a cover, flat panel or combo flip-flat panel
The DarkLight Cover/Calibrator (DLC) is a DIY project to build a motorized telescope cover, flat panel, or a combination flip-flat system. Its modular design supports various setups: a 12V light panel without a servo for a wall-mounted calibration panel, a servo-only cover for sky flats, or both integrated into a flip-flat mechanism. The DLC also includes optional dew heating to reduce extra equipment and cabling. With available drivers, it works with ASCOM or INDI.

JAVA project represents the realization of modern astronomical algorithms related to the orbital movement of planets, satellites and small bodies in the solar system by solving Kepler's equation and additional astronomical and mathematical libraries
...It represents optical systems as maps from a starting surface to an ending surface. The surfaces are themselves specified as truncated power series. The maps include path lengths; the library calculates interference as path length differences, and shearing is handled correctly through mixed-form maps. The library includes a rudimentary front end for interpreting a simple language for optical-system specification, a dll, and an optical glass library of commercial glasses.
Convert data file from fixed width format table to CSV
...I am using this utility to import astronomical catalogs provided as flat tables at CDS ftp-server into postgresql;
Build:
$ make all [cc={icc|gcc}]
Install:
$ make install [prefix=/path/to/your/bin/directory]
Example of usage:
$ gzip -dc table.dat.gz | fw2csv --stops=4,10,11,20,30,36 -d '|' -header 1 | psql wsdb -c "copy mytable from stdin with csv delimiter '|'"
For the list of available options call
$ fw2csv --help
PRTG Catches Network Issues Before They Cause Downtime
Threshold-based alerts flag problems early, so your team can act before users notice, not after.
Reactive troubleshooting usually means hearing about a problem from frustrated users, not your monitoring tool. PRTG sets threshold-based alerts across devices, servers and applications, notifying your team by email, SMS or push the moment a metric crosses a set limit. That means catching a failing disk or overloaded server before it becomes an outage and getting time back from firefighting. Start a free trial and set your first alerts today.
Univerx, a Solar System simulator in OpenGL 3D to show planet's translation and rotation. Includes phisical simulation of orbital movement, textured and lighted planet surfaces and customizable interactive view of the model.
