Roundtable – Linux User Net Notes – NCS – K7SAK – 10/28/19

News and Discussion: Adobe cancels all subscriptions in Venezuela without giving refunds (at first) after President Trump leveled sanctions. This raises the question: is software as a service a sustainable and healthy model for business?

WA9ONY Astronomy– image processing. Take many hours of photos, stack them, filter noise level, and find faint stars. Moved to GIMP. Why keep paying when there’s excellent open-source software available? Why make a student go get an expensive subscription?

N5NWI: discounted through student at Clark: uses premier.

KC7MM: Worked professionally as consultant- advised clients to evaluate your tolerance for losing software when using proprietary or commercial software. With open source, you can “freeze” it or “fork” it.

KG7GDB: imagej.nih.gov— Image processing for astronomy and 2d slices to 3D, stacks (bunches of imagery for noise-reduction), fractals, etc.

Blender is used in professional movie production nowadays.

KF7JFA: Does kernel and X11 driver development for wacom tablets. Professional animation– blender is well used and in-house developed software since early 90’s.

KJ7DED: Free as in speech doesn’t mean you can’t get paid for it. Example: Redhat linux.

KC7MM: Forking GPL software means it has to be re-done with GPL.


August 26, 2019: Pine64 Single Board Computers by NCS, KC7MM-Russ

A look at two Single Board Computers from Pine64 to see what potential they might have for operating as computers attached to our mesh net. Both boards are much like the Raspberry Pi.

* Rock64

  • Wiki page with OS images, technical details.
  • 2-3-4 GB ram: $25, $35, $45. Gigabit Ethernet, USB 3.0, eMMC slot up to 128 GB.
  • Runs Android as well as Linux, has a NextCloudPi image available.
  • Looks good as a server, not so much as a desktop.
  • ROCK64 OpenMediaVault NAS instructional video on YouTube.

* Pine H64 Model B

  • Wiki page with OS images, technical details.
  • $36 2GB, $45 3GB. Lots of I/O ports, Gigabit Ethernet, Wifi/Bluetooth, USB 3.0, eMMC slot up to 128 GB
  • Also runs Android
  • Looks like a good candidate for general use and development, server or desktop.

Pine64 is all Open Source. Doesn’t have the breadth of community support of the Raspberry Pi.

August 19, 2019: DistroTest, Pine64

July 15, 2019: Network bridging explained
