>"Way back in the 70s when I was building logic circuits, I was warned repeatedly that I'd have to get a few things right, or risk "locking up" or "burning out" the CMOS chips I was using. The bogeyman was "Signal Reflection", but no one could tell me what it was, or why it was so bad."

[...]

>"I remember hooking up a television, again, back in the 70s, and we had to change the cable connecting the aerial, because it was 75-Ohm, and we needed to use 300-Ohm.

I was confused.

It was wire, and certainly if you connected a meter to measure the resistance, you didn't get 75 Ohms, or 300 Ohms. You got effectively 0 Ohms. It was wire, after all, and wire didn't have resistance.

No, but it has impedance.

When you have a current flowing down the wire, you have electrons in motion (although not as much as you may think!). And if you have a moving charge, you have a magnetic field.

So when you start the current, it starts to create the [temporarily changing] magnetic field, and a changing magnetic field creates a voltage in the opposite direction.

So that opposes the current, giving a dynamic [instantaneous] resistance.

So starting the current off down the wire causes a [instantaneous] resistance, and we can then talk about how much resistance we experience. That depends on a lot of things, but it serves to show that

even just current on a wire is a complex thing."

Observation: Changing the current in an existing circuit might not result in an instantaneous change in the current -- that's because an instantaneous change in current results in a instantaneous change in the magnetic field surrounding the current, and an instantaneous change in the magnetic field surrounding a current may in turn act to influence the exact amount of current which can be carried in an infinitesimally short time period...

Over a very short, but not instantaneous amount of time, these forces balance, and the current does indeed flow, but that does not happen in an instantaneous / infintesimally small - unit of time...

Fascinating!
Focusing on revenue and revenue growth makes sense for some companies, especially ones where you can expect economies of scale to eventually become a major factor.

When the company's business model is this transparently an elaborate scheme to sell dollar bills for $0.75, though, focusing on revenue starts to seem like either committing or being taken in by a very elaborate version of lying by omission.
I’d call this a “rational” diet; unfortunately, most of the diet plans I find on reputable sources are for “constrained” people (vegans, vegetarians, or people that are allergic to something). Being unconstrained, I’d assume I’d have an easier time finding a sensible diet that has all the nutrients and energy I need while being reasonably eco-friendly and wouldn’t break the bank, but that’s not my experience. Would you recommend any sources that I could use to build such a diet plan?

Why do I ask for some reputable sources? My attempt to build a plan according to my “common sense” (similar to your advice actually: dropping most of red meat, eating more legumes etc) lead to me developing hypotension and iron-deficiency; of course I can adjust the diet now I know this, but I’d rather do it the proper way this time.
I don’t want to subsidize Walmart with my taxes. That’s exactly what you’re proposing, and in fact what happens. Companies underpay their workers, who end up needing government assistance. In the end my taxes go to supporting a company that I would never shop at.

Maybe we need a hippocratic oat for microsoft CEO's. Or maybe there already is one, like the one we have for bankers. But somehow they are still corrupt, big surprise.

It doesn't matter if it's a good freedom, the chances of the US repealing the 1st Amendment any time soon are basically nil. You'd have a better chance of getting Apple/Amazon/Google to voluntarily split up their own companies out of the goodness of their own hearts -- it just isn't going to happen.

The only argument that actually matters here is whether or not restrictions on corporate structure actually do violate freedom of association or not.

I'm reasonably skeptical that they do, given that the 1st Amendment hasn't stopped us from enforcing antitrust and monopoly legislation in the past. Yeah yeah, Citizens United and all that, but we regulate companies all the time.

But I'd still want an actual lawyer to weigh in on that, I wouldn't feel confident saying that there aren't limits on how far we can go in that direction.

It is definitely about cost. An SFP module for 1 gigabit copper ethernet is $20-30, and a typical consumer router has 5 ethernet ports. For $100-150 you can buy a consumer router with 5 ethernet ports, a wireless card, and even USB ports (to e.g. host a storage server or connect to a printer).

It’s reasonable, just hard to take seriously coming from a company that skirts around laws and regulation as a business model.
I feel like a lot of people here are missing the point of professional agreements or organizations like this: protecting the engineer from the consequence of saying "no" to something unethical. Almost every software engineer I talk to has a story about something they did early in their career that was ethically dubious. Hell, I work at a fairly senior level in medical software and I still feel like I'm taking risks by saying "no" to things that are clearly sketchy.

Also, it makes sure we have a ethical framework to work with. Right now, it's every engineer for themselves. You won't do something that sits in a legal gray area? Companies will find someone hungry enough to do it. If we're all staking our professional reputation on it, there will be fewer competent takers.

Personally, I think it will also be a step towards better legitimizing the profession and being more inclusive. Many folks have started equating Software Engineer with hyper-rationalist orthodox libertarianism and... the stereotype isn't far off from what's typically upvoted in these sorts of communities.

Anyway, them's my thoughts on this. I definitely support this sort of notion.
Of course. This is gate-keeping with a sprinkle of regulatory capture.

My favorite quote:

>Many of our critics, ..., believe that Uber and our gig economy peers have failed drivers by treating them as contractors, and that we will do anything to avoid the cost of employee benefits like health insurance. Given our company’s history, I can understand why they think that.

Pray tell, what is this company history you're talking about? Come on, be specific. And did those policies get you the market-share you have now?
It is very reasonable, even if it does benefit Uber. He should really be going the step further and saying, “Health Care shouldn’t even be tied to employment in a developed nation,” but that would be too political.

The fact that we have millions who just lost health care during a time when they need it most should be the nail in the coffin of our current system.

It’s been hugely flawed for years, and now it’s just a joke. Some problems have very simple, but very big and different from American status quo solutions.

People who love markets would still be able to pay a premium for what they want, just like they do now with all the care providers who have totally bailed on taking even the best insurance.
Yeah, that's also interesting to think about. Like, when you forbid something to plebs, you don't really want to cut off the ability for yourself too—there's that ‘research agency’ which needs to run things on Twitter, or whatever comes up tomorrow. So you'd think sysadmins would come up with something so others can't use Tor but you and buddies can.

But maybe that would mean giving the sysadmins too much inside info.

I also discovered recently that the FSB and company aren't considered monolithic, and a few departments are doing their own things in a sort of ‘competition’. So yeah, it might be that some of them want Tor and don't want the hassle of setting up the exclusions.

PSA: I've worked disaster relief/reconstruction in Houston, New Orleans, and a few other places. If you come across a fridge with the doors taped shut DO NOT OPEN IT. If you come home after power was lost for more than a day or so, TAPE THE DOORS OF YOUR FRIDGE SHUT AND DO NOT OPEN IT.

It's not worth it. You will never make the fridge use-able again.

If you have to leave ahead of a disaster, consider emptying your fridges/freezer and propping the doors open.

== You can tell it's a conspiracy theory because it's filled with stupid internal contradictions, like that Times article which claims the Russian accounts are both human and "cyborg", which they define as "automated but with human involvement" (which is it and why automate if you still need human involvement), or that the posts are simultaneously pro-Brexit and also pro-Remain==

Processes being “automated with human involvement” is not new or a hoax. It happens all the time, all over the world, in all types of industries. Ask someone who works in manufacturing, writing bots, or in customer service.

And yes, the posts can be contradictory. Especially because the motive (as outlined by a bi-partisan Senate Intelligence Committee report) is to sow chaos. Promoting two extremes certainly helps do that.

FYI, I’m not going to respond to this thread any further. You have clearly dug in to your stance and don’t seem open to other views. You are literally creating a new, unfounded conspiracy to de-bunk an established, documented conspiracy.

I don't know how much you know about payments in India, but they are, from what I have heard, fairly evolved and advance.

In fact, in India there are 4 different ways in which you can do online transfers across the banks (NEFT, RTGS, IMPS, and UPI). The latest iteration, UPI, is indeed state-of-art. It lets even companies like Amazon, Google, and PhonePe, which are not traditionally banks, to offer ability for people to do transfers from their Bank account. QR Code for UPI apps are very commonplace at least in metros and it enables nano transactions without really a fee to small merchants and users. There are lot of fail safe mechanisms and safety features built into the protocol and a user is not really hostage to the bank or the payment app as you can switch both at your will.

I hate to say it but based on this source it looks like global power sourced from coal power has gone UP every year since 2011. I found this source on google and am know nothing about its political agenda, however the slider it provides to see total coal power by year seemed very handy.

https://www.carbonbrief.org/mapped-worlds-coal-power-plants

2011: 1.679 .MW
2012: 1.740 .MW
2013: 1.799 .MW
2014: 1.848 .MW
2015: 1.917 .MW
2016: 1.969 .MW
2017: 2.002 .MW
2018: 2.018 .MW
2019: 2.044 .MW

The growth appears to be coming from new plants coming online in each of those years primary in India and China.
Rephrase the second point as "everyone must work for a living", and it becomes clearer. Your second point becomes a corollary: people can only be cared for if they work. Your last paragraph is only possible if we want to allow people to live without working.

But many would see that as morally repugnant. Not everyone, but a majority, and especially a politically powerful plurality. That is what you will need to deal with to make a change.

I think this is more about lack of coordination (i.e. political reasons) than something like a natural first mover disadvantage.

That is not a fair characterization of the discourse.

30% for matching buy/sell orders? Do you have any idea how insane that is relative to what NYSE charges?
You’re not subsidizing Walmart. You’ve decided that workers should enjoy some standard of living but are unwilling to shoulder the costs of providing it (e.g. through taxes). Instead, you’ve kicked those costs to Walmart. Walmart is subsidizing you.
You had your freezer on a switched outlet?
I think that this is the tip of the iceberg. Its not just about Uber. Its not just about the gig economy in general. Its about the entire economy.

There are multiple forces at work. One aspect is the actual long-term debt cycle which people don't realize puts pressure on everything. The other thing is the effective de-regulation and loosening of employee protections.

Another part is tech monopolization.

We actually need an entirely new high tech global economic paradigm. We need to re-invent money and government with advanced distributed protocols. That will allow us to holistically and locally track and regulate resources with a universal basic income (or hopefully even a bit more than basic) while we scale-up deployment of automation.

Huh? I completely disagree with the premise of the article.

I will start by saying that monopolies are bad and we could do away with them. That said, current actions have little to do with their legal and market position, but rather geopolitical place US is in today.

There is a clear indication that US executive branch decided to go after China. And if history is an any kind of teacher, the rest of the government will eventually fall in line ( especially since it is hard to argue that China is a benevolent dictatorship ).

US does not have a TikTok problem, because of tech monopolies. Monopolies just may end up benefiting from US foreign policy.

Didn't Uber disrupt an industry that was already very well protected by government regulation, and seems much more exploitative?

It costs around $100,000[1] to be allowed (by the city) to drive a taxi in New York ($1.3MM in 2014), for a job that pays on average $43,000[2] per year - which involves driving an average of 70,000 miles per year - which at an average speed of 4.7mph[3] works out to $3/hr (not counting waiting time).

It's still not a living wage, but making $9/hr[4] just by owning a decent car seems like progress.
