@dalias I worked for a guy name Amar Bose for a while who got his start designing PWM-based power amps, then speakers. I'm just a SWE, but I like to tinker with HW interfacing too. Sounds like a fun project you have.

@dalias Yes. S/PDIF is the perfect example of opto-isolated self-clocking square waves. Depending on your bandwidth needs, I'd go with whatever is in common use for S/PDIF circuits.
But I'm just a SWE... -

@clive I already hear that Maine coastal rental businesses are seeing 90% of their Canadian visitors cancel summer plans, threatening the survival of their business. We all blame Trump, but many will not acknowledge it in public because of fear and shame.

@inthehands Did not realize Rupert Murdoch is on the Tesla board, just exercised and sold $13M worth of options a few days ago.

@inthehands Responsibly, I decided to add just $100.00 more of TSLZ and TSLQ to my portfolio, just to keep the scent of impending brand-death fresh...

@inthehands OK, my first #TeslaTuesday
My little portfolio has appreciated 20%, including about 10% today, though it's been quite volatile over the first week.
I'm not advising that anyone invest money they can't afford to lose in this way ! -

@inthehands I imagine the fund is "managed" by some traders doing the actual short trades, and this fund gains any profits, suffers any losses, but you are limited to losing your investment, as opposed to the actual short-traders, who have much more downside exposure, and I assume more upside potential as a reward. I'll do it on a very small scale.
My account tools show the history of the fund, so I could look, but why... -

@inthehands I don't really understand these "stocks", but I'd be willing to spend $200 to try it out, willing to lose it all. And I have an account...

@dangillmor @pluralistic I'm ready to join the software engineering counter-revolution. Jail-break is my middle name, and I have some rusty skills.

@gleick FWIW, I was with a medium size tech company about 15 years ago, and we had excellent human tech support, and it was rarely needed.
One big reason, IMHO, was that the support budget came out of the sales budget.
The dynamic this setup was that sales was forced to balance "requests for new features" with "cost of supporting poorly designed or executed products".
I think that's a very rare choice these days. -

@photomatt FWIW, in the US, we can't even keep kids and crazy people from getting military-grade weapons, so I'm suspicious of anything that says "let's start enforcing ID checks for social media".
I was a 16yo kid once. I know what happens when you tell them they can't do something.
Crazy idea - require the advertising-surveillance industry to report identities they suspect to be underage, trying to do underage-things. They track it, profit from it, model it. Make them share it, like a tax. -

@eff I've contacted my Senators King and Collins with the message you suggest.
Patent trolls are an abomination to all people who actually create things. -

@taylorlorenz I'm going to push back on this framing "Democrats become more comfortable embracing denialism"
You can wonder, for example, the effect of various voter suppression efforts. People who voted for an Abortion-rights question but not Harris ?
But there is not to my perception any denialism about what just happened.
It's clear. Half our neighbors, on average, wanted this. Deal with it. -
