I always believe[d] that the number grew around the limit, not the other way around
Light dawns
Light travels at around 300,000 km per second. Why not faster? Why not slower? A new theory inches us closer to an answer

Yes, he's a humanoid robot

Yes, he's getting a hand-mounted laser

What's the worst that could happen?

This weekend: experiments with high voltage!

Nixie tubes, display technology of the 60s through the 80s, form a great contrast to the current state of display art, which I would say is programmable LEDs.

A cold cathode display (like a Nixie) takes high (165+) voltages whereas LEDs are 1-3 VDC. A Nixie tube has no "encoding" - if there are 12 different display values there are 12 pins to address each of them individually (and a common). Programmable LEDs typically sit on a (shared) bus and require 2 pins to set any value on each of some large number of elements.

The shift of complexity from a central point to distributed points, close to the components where it's needed, was only possible with the reduction in {size,power,cost} to implement the needed complexity.

In the end, this was a major effort to wire up and power - but just look at that crackle and glow!

I once told a recruiter from Uber that from what I'd heard I wouldn't be a good cultural fit at their firm and that they'd best not follow up with me.

I had no idea how good a decision that was.

Here's another... #DeleteUber

+Uber take a look at my ride and payment history: I spend a lot of money with you. Say goodbye to that. You're convenient but other things matter.

I just picked up an Orange Pi Plus and want to install Ubuntu on it - the Downloads page on their site has a dead Google Drive link and a Baidu link that wants me to install a Chinese language client to proceed.

The forum has some people asking questions about this but with no useful answers.

Does anyone here have a working link to the current Ubuntu/LXDE image for the PC plus?
