Found myself setting up a new laptop recently and found it difficult to think of all the useful programs I'd be reached for down the road. Thought it would be nice to start a list... Here's what I've come up with so far. sACNView - Debugging tool for Streaming ACN Artnetominator - Debugging tool for artnet Wireshark - General Network data analyzer/logger OSC Data monitor (Looking for a better option here..) - OSC Monitor/debugger Various console offline software Vectorworks - Drafting Software. draw.ioFlow chart software/generator Lightwright - Until someone finally gets around to making something better... Office Net3 Concert - Configuration for ETC gateways/nodes/dimmer racks Pathscape - Configuration for pathport nodes/switches/etc Dimstat - Configuration of sensor+ dimmer racks IP Switcher - Small utility to switch between different ip configurations for public vs private networks/venues putty suite - ssh, telnet, and sftp clients for communication with switches/headless machines ultravnc - Most flexible windows vnc client i've found. What else do you find yourself using regularly? Previs I assume, probably adobe suite, etc... what else? Honorable mentions for mac: iTerm - terminal replacement homebrew (for telnet among other things... cmon apple).. basically a package manager for OSX virtualbox/vmware for windows. Edit: this looks like it got moved to the general forum, which is pretty cool, though I think that it will make it harder to filter down to what "useful software" might be for a specific usecase. For context, everything I posted above was software that I would desire on a computer focused on lighting. If the software you are adding below isn't immediately obvious as to what field it would be useful for please include that in your response. Some non-lighting software that I'll preemptively add to the list to get out of the way. Autocad - drafting software. Autocad and vectorworks are in a competition to see who can make a less appealing piece of software. sketchup - Quick drafting/modeling software. qlab/scs/similar - Sound/video playback Adobe Suite/Finalcut/etc - Video/Image editing Logic/similar - Audio Editing Isadora/Watchout/Resolume/VDMX/similar - Video/media playback Max - The swiss army knife that no one needs, but everyone loves to use... VLC - The swiss army knife that everyone wants, and everyone needs.
