I'm trying to figure out what ROS2 is -- judging by the docs and tutorials it seems like a very low level and abstract piece of complex software but I'm struggling to understand its practicality.

Can someone provide an ELI5 or like a few sentences of a "pitch" style overview?
I'm going to point something out that MKBHD mentioned in his first impressions I don't see anyone talking about: the "smart case" is the only way to turn the headphones off If you walk away from your desk or whatever without putting them into the case, they'll die after a few hours. There's no of button, they don't turn off when you disconnect from bluetooth, they don't turn off after a certain amount of inactivity.

This'd be an instant killer for me.
Oh yeah stubbornness isn’t one of the traits I meant as good. I only meant that stubbornness is all that allowed me to keep certain good traits from being stamped out.

It can just as easily (and in my case also sometimes has) prevented some bad traits from being stamped out. So I need to consciously go way overboard with “I could just as well be wrong” to balance out my natural stubbornness.

Sales tax and VAT are equivalent assuming everyone plays by the rules, this is economy 101.
The difference is in the implementation and where places for abuse are. With VAT you charge it everywhere in the chain and then apply for refunds if the total you paid is higher than the total you collected. The argument is that this makes VAT more difficult to game but this doesn't sound very convincing seeing how the whole criminal industry was created around gaming governments for fraudulent VAT returns. This caused the governments to create more and more reporting requirements making life more difficult for honest businesses. VAT also causes liquidity problems if you rely on fast refunds. This makes it difficult for small businesses because liquidity is a bigger problem for them. What often ends up happening is that they just have higher prices to make up for delated VAT returns.

Living in a VAT country I am not a fan of it. I think taxing consumption is a good idea in general but the burden of the current implementation is too high.
It is not being left to die because you can’t afford treatment. It is bad enough that we don’t need to exaggerate.
"All of racism fits into that paradigm. Racism is a system for causing poor black folks and poor white folks to fight against each other instead of fighting with each other against the systems oppressing both of them."

Your statement contradicts itself. If in fact the oppressors are targeting both white and black people to maintain power, then they are by definition not targeting only one race and would instead be classist/elitist.

Also, not all racism is about people getting richer. Some of it was done on their (misguided) principles without financial benefit, or even to their detriment as the civil rights movement grew.

I fail to see how the citizenship test would lead to the rich getting richer.

Well I have some bad news for you, they don't believe they lost the election.
So you're born 15 years into the reset.

When you're 18, you're about halfway through. If you work hard for 10 years to accumulate wealth, add value, whatever, by the time you're ~40, it's about to all get taken away. What's the point?
Why do you?
That's my understanding too. But if the RSU was granted at $50 and the price drops to $30, the employee is going to be quite upset (this could've happened to me at a different company if I had taken a certain offer). That's why I said that the share price continues to matter to the company, even post-IPO.

New Amiga Game ‘Scourge of the Underkind’ Coming Soon
For your self-fulfilling prophecy theory to be valid, venture capital would have to be able to ensure that your contribution margin is staying constant. Eg: if you make $1 per sale in CM at $1m in revenue in 2020, will you also make $1 per sale in CM at $100m in revenue in 2025? The reality is that unit economics change massively with scale and with time, and only a select few companies get the contribution margin to be constant (and even fewer achieve a constant contribution margin that's in the right ballpark). Therefore, venture capital can accelerate a successful company or delay the demise of an unsuccessful one, but it won't change the eventual outcome.

If you need mathematical proof for this, just ask yourself how many net new customers would you have to add to a business every year if you are at $100m in revenue and have an annual churn of 10%. Yep - you'll be running out of your TAM pretty quickly at that rate. And then add to that the fact that each new net customer will likely keep getting more expensive to acquire [1]. To get to $100m and stay there of even grow beyond that figure, the business fundamentals (first and foremost: churn) need to be good.

You can also think about it from this angle: why is it so rare for the same founder to continuously churn out one IPO after another? With each next attempt, they should be getting better at it and have more people willing to support them. The answer is - it takes a ton of stars to align correctly, and money alone won't fix your unit economics at a moment in time, let alone over many years and 100x growth in revenue.

> Storage costs, despite being in freefall still are still in the hundreds of dollars per kilowatt hour range. And it's kind of moot since the total amount of storage produced globally is still a fraction of what is necessary to make renewables feasible as a primary source of power.

Funny that you also fail to mention that although storage levels are very low, we are still very far from reaching the market penetration of requiring storage. Transitioning a world's electric grid takes take, decades, plenty of time for storage to drop.
Are you trying to refute physics of breathing? Most of the virus spreads by air. The world of physics goods can be accomplished without breathing on other people hence the physical distancing. What world are you living in?

This is such an empty criticism. Universities are not job training facilities. You want people who have the exactly right skillset? Hire smart kids and train them, you know, the way it's been done for hundreds of years.
How are you "giving up control"? Having stuffed published in literally any sort of journal, newspaper or anything has certain formatting and layout requirements. Just because you format it in the "stories" layout doesn't mean you're giving up control over your content.

AMP also still properly directs both ads and analytics metrics, and in some cases can be hosted on caches you own, but even if not, having it hosted in a different cache is also not giving up control.

At no point in this process are you losing control of your content. If you don't want to participate, then don't. Creators decide to put their content on TikTok, Youtube, Instagram, Twitter, and now this is yet another avenue they can put their contents on. How is it any different?
> There are people in FAANG the dont even have any post secondary making > 500k a year as "Software Engineers". How this works without total chaos is that each company has a rigorous testing procedure for candidates.

That's what I expect from a credible credentialing organization, to be able to tell me that person X meets a minimum bar. Right now they get a bad press because, especially in the medical field, it's more about gate keeping and lobbying than actually enforcing standards and protecting the public.

I would argue that surely someone making that type of money at a world class organization like Google would have no problem passing any engineering exam.

I think that's being uncharitable to "business-school leaders".

Ignoring the people who are going to business school for a two year vacation, which a lot of M.B.A.s do, there's a growing contingent of people who are going in with technical skills and experience. I think business schools deserve some credit for that.

There are still plenty of people from non-technical backgrounds hoping to be your traditional M.B.A.s, but the culture is shifting in the right (IMO) direction.

Australia is not targeting 100% renewables by 2032. Your own link says 'could be'.

Australia is currently at ~24% renewables. Note this is also because Australia has substantial amounts of hydro power that can be used in conjunction with solar.

Haha, I'm the wrong person to ask. I was fortunate enough to be in a hands on senior role, and I promoted a very light Java++ style, to be learned in a 2 hours seminar: immutable collections, case classes, pure functions, impure logging & exceptions, sparingly used interface polymorphism, recursion, filter/map/flatmap/fold. Scala: The Good Parts. To this day I have not learned the first thing about implicits or type variance, and probably there are many many many more Scala features I haven't even heard of. The biggest challenge was helping the rest of the team avoid writing inscrutable sbt plugins. The plus side, it makes little difference Scala2 vs. Scala3. The downside, some teams may scoff at such a mundane approach.
That's not a challenge right now, but yes could become more of one.

No, you must pay VAT on intra-EU B2B transactions too. The accounting is more complicated because the buyer pays rather than the seller, but it is still there.
> Can you build a nuclear reactor in less than a decade cheaper then storage and renewables? The evidence indicates no. But if you can, the world would love that, just demonstrate it's possible.

Sure, the USA got to the moon in less time, in the 60s. As a technical problem it's easily doable. Even in quantity it could probably be done. (There are some questions of making many of the larger parts at once, such as the containment vessel, and if enough factories remain which are capable of it - in the USA. If it was worldwide, that's not an issue because China now has that capability.)

On the political side, it's either impossible or pretty easy, depending on the motivation. It's currently impossible because of the nuclear boogeyman and all of the obstacles that opponents can throw out. (It is implied that these obstacles have no ultimate merit.)

However, if we had a focus on pollution-related deaths, which are like a never-ending global pandemic - 10k deaths per week from coal pollution alone - then we'd probably find the will to fix it.

Considering that (estimated lifetime) deaths by all Nuclear (including Chernobyl and Fukushima, but excluding bombs) are less than one week of pollution deaths, it'd be an easy sell if we actually looked at numbers.

In the Lazard study, do you see what they budgeted for non-panel costs in utility-grade solar? In residential the cost of the panels is often quite a lot less than the total system cost.

> Until then, it's hydro, batteries, renewables, and demand response full speed ahead.

Hydro is almost tapped out, and not carbon neutral. But I agree we should build it everywhere possible because it is dependable, and comparatively cheap.

Batteries are not gonna happen for grid-scale power. A few terawatt hours (a minimal estimate for the USA's storage needs) would be every battery produced in ten years, even with a ramp-up, and the pollution from the mining and manufacture would be huge. They're a great solution for certain storage solutions though because they're solid state unlike flywheels and pumped hydro storage. Places where convenience weighs heavily will adopt batteries.

Renewables are absolutely the answer - as much as they are. Any generation that can be peaky, should be solar and wind if possible. Like if we built desalination plants they'd be a great use of intermittent power. Or if they're just charging the storage layer. Neither is free of pollution though, like batteries they merely front-load it and appear green when operating.

You're 100% right though about full speed ahead. I'd rather start on solar today, which I don't fully believe in, than spend years arguing and be stuck where we are today.
It might be naive, but I would have expected that there is some approval process for stuff like that. It's an inherently dangerous thing to incapacitate people without harming them. An example of how this went horribly wrong was the Moscow hostage crisis, where a gas designed to incapacitate people ended up killing a lot of them.

I don't see any acceptable reason to introduce new agents here unless they are properly studied and considered less harmful than the existing ones.
There are many reports of people self-rationing insulin and dying as a result. That's as close to "left to die because you can't afford treatment" as it's possible to get without murder charges.

Sticking your fingers in your ears and saying, "Ah ha!", does not an argument make.

I spent 6 years in the solar industry, working at both a start up and a fully vertically integrated behemoth that manufactured panels and built plants and while I'm no longer in the industry today, I'm confident I am up-to-date on utility-scale storage progress and it is not summed up by, "electric car batteries!"

Auto-suspend on lid close is a feature that I hate. Even on my work Windows laptop, I can never be sure that it will suspend, and half the time you wish it wouldn't because then your VPN connection will time out, etc. Thus people walking around with their laptop open a couple of inches. Much better to completely disable auto-suspend and get used to just pushing the suspend button and waiting the couple of seconds for it to react and then closing the lid.

That's the main reason I can't even be bothered to configure this (as in from the GUI) on my Linux machines.
I might be wrong because I'm not an American, but the way I understand the free speech is that it guarantees the government can't punish you for saying something. It doesn't guarantee your speech a right to have instant reach to millions of people. Facebook "censoring" someone is no different than a newspaper in the 20th century deciding to not publish your letter, or a book publisher refusing to publish your book, or a store owner removing your graffiti from their window. You had a right in 20th century to say anything you want to whomever you wanted. If you wanted to reach a ton of people at the same time, you either built that reach manually or you had to convince someone (TV, radio, book publisher) to help you. And it is the same today. You can say whatever you want to a friend, coworker, family member. And you can also say whatever you want to every citizen in the USA. But you're not guaranteed a right of any company to help you in that endeavor. If Facebook, Youtube, Amazon, Paypal don't want to help you in reaching people it is their right to do so. Youtube blocked you? Make your own website. Amazon doesn't want to sell your book? Print it yourself.

Claiming that Facebook or Twitter deleting someone's content is censorship because you have a right for your speech to have a huge reach would mean that there was no free speech anytime in history, except for a brief period of time when social media appeared before they started "censoring"
So I have an iPad Pro that has a degraded battery life after 4 years. Really, that's the only issue with it and we've determined that it's not software. It just lasts much, much less than it did a year ago. So I tried to get the battery replaced as I was willing to pay Apple for it. An Apple tech hooked it up and got a battery health report and basically came back and said, the battery wasn't degraded enough to qualify for the battery replacement service ($99). So my only option is, full device replacement ($375-ish).

I was told that the battery has to qualify for battery replacement on some devices. That's because they don't replace batteries on an iPad Pro - they always replace the entire device so unless you quality for the battery program, your only option is device replacement. Which they will do if I want but at a much greater cost. That's almost 1/2 the cost of what I originally paid for it.

I was told this directly by an Apple store employee this week. He said he literally can't select the battery replacement option unless he can prove that it is the battery and without the health report saying so, he doesn't know any way he could.
Yeah that's the exact reason I asked, especially where some of the jobs are remote.

Salary is a metric to compare jobs where the skills required and roles are identical, not to mention important for basic survival.
This is interesting. But the first thing that pops out is that there are PGE2 blocking medicines specifically related to treating nerve pain.

So it seems as if this works in humans, there might need to be caveats as to when you should and should not be taking drugs that increase PGE2 levels.
Well, a tax on profit or wealth doesn't do that.
Large part yes. But not The reason. It’s fast because of many things like that. TSO doesn’t affect single core perf much so it’s not really a factor there, and yet it’s blazingly fast. However the multicore perf is really great too.

I haven’t verified the exact numbers myself. And it will depend on the exact thing you’re running. It’s just on the order of low tens of percents.

TSO cannot be enabled outside of rosetta as it’s not exactly a good arm extension. Perhaps you could do some trickery but Apple likely prevents that.

However you can test it by making something where you know rosetta generates comparable arm assembly from the X86 one and just run comparison that way. Some sort of parallel lockfree algorithm would be the best candidate.
