file server

The company I'm working at the moment (Lozej d.o.o.) was using some old Novel OS on their server. Server was really useless except for the data storage. So i convinced the boss that it should be replaced with linux OS. At first they were skeptic, not trusting some free software, but when i found that one disk from so called data mirroring was dead for along time and no one know about it, they agreed to replace the OS. Old disks were replace with two new Seagate 70Gb SCSI. I installed it with Slackware linux distribution with disks in software RAID 1.

Noise influence area

vplivna_obmocja.jpgI made this software for the company (Lozej d.o.o.) that's doing measurements and studies of noise influence area. I wrote it in Delphi. For calculation it needs ground plan in jpeg format, from which you have to know at least one real dimension for scale calculation. With mouse you place noise sources and then define them the level in dB. After all this placed the program can calculate and draw the boundary of where to certain height of noise extends. Simple said program calculates on which distance form the source noise level drop to certain level.

Unfortunately i lost the source code, so i not developing it any more.
