Not detracting from this post, but has anyone else noticed there's a front page post about Quaternions or Kalman filters on about a monthly cadence? Wonder why that is?

In my experience in a university ECE program, you'd start with understanding the high level properties of transistors, then combining transistors to make AND and OR gates, then XOR and other gates, then MUXes and half/full adders, then flip-flops and eventually into synchronous (clocked) logic.

The lab component of such coursework did start with TTL chips but the timing of the coursework was such that you'd have most of the asynchronous logic theory taught by the time the chips came out.

Of course! A setup GUI is almost a required feature if you intend to sell or give it to a non-programmer. That just wasn't the case for me.

Very cool.

Looks similar to my own project. I think we even used the same case for the display.

Not sure you can eliminate it, but you can certainly reduce the impact and scale by fighting anti-competitive behavior . A major reason this sort of mass manipulation is so lucrative and effective is because you only have operate on a couple of platforms to reach a majority of eyeballs.

Reminded me of the Amazon show called Upload. Sort of a lighter, more humorous take than Black Mirror, but the darker philosophical complexities still surface regularly.

It almost did. There was a hostile takeover bid from Broadcom a few years back, and the US gov intervened to block it.

The key specifier word was "whitebox". They aren't speaking generally about cryptography.

Very cool. Shamelessly linking my own weather display: https://github.com/Mrjohns42/WeatherDash

Supporting EINK on mine could potentially help make it more visually compelling like yours, but I've done other EINK display projects in the past (see https://github.com/Mrjohns42/DoggieClock) and screen burn-in was definitely an issue.

Keeping it.

Every company all hands for the past year wouldn't be complete without an exec making comments about our eventual "return to work" policy, which has been delayed over and over again by surges and variants.

Asses in chairs is not a "company culture". I'm 10x more efficient in my home office than my open floor-plan desk next to the bathroom (with no sound-proofing) in a high traffic area. The 45-minute commute (each way) that I save largely ends up translating into more hours worked from me. With communications primarily happening over email and chat, we now have written records of decision making processes and we lose a lot less information along the way.

We're not a purely software company, so I understand some roles simply don't work remote, but I don't agree with a company-wide policy preventing regular remote work. I'm not looking forward to the struggle that is on the horizon.

New comment by matmann2001 in "California first state to require ethnic studies for high school graduation"

matmann2001 — Mon, 11 Oct 2021 17:31:50 +0000

High school history was awful for me as well. But a new course on ethnic studies doesn't have to fall prey to the same issues that have plagued US history education. Namely, who is defining the curriculum, what biases are they including (intentionally or not), how are educators trained to approach and teach the subject. If our education system hadn't failed so hard in these considerations for US history, it's arguable that a separate ethnic studies curriculum wouldn't be (as) necessary. Here's to hoping we can learn from our mistakes.

Well, this seems to be just about everything most people wanted Facebook to be. Yet all I see here is (mostly-warranted) doubt and criticism.

Makes me wonder if an ideal service ever does come along, would we even be able to give it enough of a chance for it to stick? Or have we just been burned so badly, we'll never trust again?

There are large rubber bands you can buy specifically to hold the filter in place on the box fan. I've seen them on Amazon.
