The only thing it doesn't have is a RTC, so I just polled a time server every so often.

That one is only a 2Kb though. They also make an 8Kb 4SFYU: https://www.digikey.com/products/en?keywords=M24SR64-YDW6T%2...

Backup: https://docs.nextcloud.com/server/stable/admin_manual/mainte... I haven't found it documented, but there are also a few occ commands to do the backup and restore that were added this year some time.

Security: https://docs.nextcloud.com/server/stable/admin_manual/instal...

But amazing to think how far technology has advanced.

Note that when a user is authenticated in this way [public key] the authentication happens without a password, as such the standard cockpit reauthorization mechanisms do not work. The user will only be able to obtain additional privileges if they do not require a password.

[Edit]: This diagram was really helpful: https://raw.githubusercontent.com/cockpit-project/cockpit/ma...

    The target server will need to have password based authentication enabled in sshd. When this is setup for the first time, Cockpit will ensure that the user connected to primary server has the same password on the secondary server.

One of the cooler things mentioned in one of the videos (https://www.youtube.com/watch?v=zmpl81WmFSo) was that they developed their own magnetic actuators that are a 10th of the cost (if you believe the marketing) of existing ones. I haven't verified any of those claims, but if true does mean their braille tablet could be an affordable reality.

The five dimensions are in the first paragraph:

More recently self - assembled nanogratings produced by ultrafast laser writing in glass were proposed for the polarization multiplexed optical memory, where the information encodi ng would be realized by means of two birefringence parameters, i.e. the slow axis orientation (4th dimension) and strength of retardance (5th dimension), in addition to three spatial coordinates [3,4] .

You then either solder on some headers and connect it to the breakout, program it, and then disconnect it when done or do some funky alligator clip madness to connect the breakout to the arduino.

Note that the pro already has the pins waiting for the breakout to be connected.

Now if you want it to do something you can see other than in the logs from within the IDE, that's when you start needing more stuff. Generally a breadboard, wires, and some components like leds and resistors come next; for making blinking lights, who doesn't like those?

As far as the computer, it can be best answered here but is just about anything you have: http://arduino.cc/en/Guide/HomePage in the getting started section.

For anyone who needs to look it up like me: http://en.wikipedia.org/wiki/Reference_(C%2B%2B)

You can do this, but if you want it to be maintainable, you'll also want to detail in the function comments this technical debt. If you don't, someone else will come along and see your sweet method (looking only at the comments) and use it where the input can be null.

Ex:

  /**
  * This does some stuff.
  * @param entry Does something with this
  * DEBT: Assumes the input entry is not null.
  */
  void doSomething(SomeObject entry) { }

[Edit] A grid would be killer too; great suggestion.

[Final Edit] Tooltips on the components/actions would help your goal of making electronic design simpler/easier to do.

  Selecting: Hold down shift and left click elements.
  Box select: Hold down shift and drag a box around the elements to be selected.
  Deselect All: Left click on the canvas.
  Move Element: Just drag it.
  Connect Terminals: Drag from schematic terminal to other  schematic terminal.
  Disconnect Terminal: Left click terminal. Click 'X' .
  Rotate Element: Select element and push 'r'.
  Remove Element: Select element and push 'del'.
  Flip Element Horizontally: Select element and push 'h'
  Flip Element Vertically: Select element and push 'v'
