I am confused. What would you like about CF that needs to be open sourced? Is it the front end? The datacenter operations software? Their algorithms? How would that solve the problem of portability? If there is anything to cringe, it is emotional appeal to OSS without thinking it through. Cloudflare is a massive service provider, not a database engine. OSS has a huge significance in basic building blocks of software - things like openssl lib.
Based on one of the links within that article https://www.cnbc.com/2021/10/01/stocks-are-at-a-70-year-high... I think that by "U.S. stocks" they mean "stocks held by U.S. households", but I'm not 100% sure and I agree that's confusingly worded.

Payroll taxes are paid by the employer.
Rust is nice, it tries to solve certain kinds of memory bugs

But it introduce even bigger issues; slow build times

Being able to iterate SUPER QUICK is very important, you want to be able to test and see results as fast as possible, so you get to fix bugs or implement feature with ease

Imagine you get to work on super import product that needs super low latency and close to 0 downtime

You notice a bug, you have to deploy a fix ASAP

If your language makes you test/deploy the issue in hours, then it's very bad
I think there's something in the middle. One does not need to learn everything, of course, and it pays to learn many new key concepts. Groundbreaking concepts help us identify new problems and find simple solutions. Another advantage of learning key concepts is that we get to connect all those concepts, and connections beget breakthroughs.

As for what concepts to learn first, I think Feynman's method helps: "You have to keep a dozen of your favorite problems constantly present in your mind, although by and large they will lay in a dormant state. Every time you hear or read a new trick or a new result, test it against each of your twelve problems to see whether it helps. Every once in a while there will be a hit, and people will say: 'How did he do it? He must be a genius!'"

Well, the system is a patchwork of systems.

The top 50%ish get coverage through jobs that is mostly fine.

The bottom 25% get heavily subsidized plans (often free) from both state and federal programs.

There is a hole there in the middle, but it may be possible to tweak a few programs without throwing out everything. This is basically what ACA tried to do with the backing...
I liked your talk, and the talk you referenced by Timothy Roscoe [0]. My understanding of your talks is that the issue we seem to be running into with system architecture design is that OS and userspace developers are clinging desperately to a dead model of the system as a homogeneous array of cores attached to large bank of unified memory. This falsehood is so deep that systems basically lie to us about 95% of their internal structure just so that we can continue playing out our little fantasy in obliviousness.

The biggest component of that lie is the unified memory assumption. To be fair to OS & app developers, writing for NUMA is hard, there are enough invariants that must be continuously upheld that it's impossible to just expect authors to keep everything in their in their head at all times. And using a language like C, described as "portable assembler", does not help at all.

Enter Rust, where the novel ownership system and strong type system allows encapsulating special knowledge of the system and packaging it up into contained bundle that can't be misused. Now you can compose multiple of these un-misuse-able (it's a word now) lego bricks reliably because the compiler enforces these invariants, freeing the author from the burden of reflecting on their design from N! perspectives every time they add a line. (Well, they still reflect on it, but they are privileged to reflect on it right after they make a mistake when the compiler complains instead of in an hours-long debugging session using a debugger or, worse, a specialized hardware debugging device.)

---

Your talk focuses on no_std, which is really a foundational necessity of such a new OS (the term "Operating System" feels too small now, maybe "Operating Environment"/OE? idk). I think the next important component is a path out of UMA-land, which I don't think is fully solved in Rust at the moment (that's not a knock, it's not solved anywhere else either). There's an ongoing Internals thread that started as a discussion about usize vs size_t across different architectures and now has dug down to questions such as "what even is a pointer?", "how are pointers represented as data?", and "how should you convert a bucket of bytes into a usable pointer?" [1] -- these are exactly the type of questions that Timothy's talk reveals as important (and has hitherto remained unanswered) and that you hinted at.

During the discussion, Ralf Jung presented an interface that would enable constructing a pointer from an integer by also separately identifying its provenance; I feel like this is a good direction.

/// Returns a pointer pointing to `addr`, with the provenance
/// taken from `provenance`.
fn ptr_from_int<T>(addr: usize, provenance: *const T) -> *const T

---

What do you think of my summary? What do you think of the ongoing discussion on this Internals thread about the right way to construe Rust's memory model? What do you think of think of this idea presented by Ralf?

Two things I would add:

1. Think about any unwarranted assumptions you might be making about context. Is there some environment variable that needs to be set that has become unset or had its value change? Did the OS version change? Some config file?

2. If you can find a working version of whatever it is you're trying to fix, do an incremental search to find the differences between that and the broken version. If everything is in version control this is easy. If not, incrementally change the working version to be more like the broken version until the working version breaks. (This technique is especially useful when dealing with large legacy code bases that you are not intimately familiar with.)
Social security has never made sense to me. Not only do wealthy people get to collect social security, but they actually get paid more than less wealthy people, by design. All the money is going to the people who don't need it. Why would the left support something so unequal, and why would the right support a forced savings plan with such bad ROI?

It seems so wasteful. Its a terrible deal for everyone involved, really. Those who made a lot of money and had to pay a lot into SS made terrible returns and would have been better off investing the money. Those who only made a little, and only paid in a little, do not get paid enough to live off of anyway and would have been better off seeing that money in their paycheck.

The only people who benefited from SS were the people retiring soon after is was implemented. Everyone else is worse off, but nobody wants to get rid of it because then they won't get to collect.

Hey all! I'm building a BI environment for software teams. As a manager, my biggest frustration with comparable tools is 1) they're built for product managers as "software delivery metrics" and 2) their metrics are prescriptive and dictate process.

BLDBTR is a BI environment that gives teams full control over their data. It decouples performance metrics from process and structure so that as your org or code structure changes, your metrics can change with you. At one org, we moved from functional teams to a project based, matrix type org structure and only needed to adjust a few group by queries in the chart builder.

Having this tool has also allowed me to see stats that I otherwise wouldn't have or would need to manually compile. For instance, how much do my managers code? Are my contractors worth the investment? How long does it take a new engineer to ramp up - and what does the ramp up look like? Whether you're an engineer, manager, or executive, you can see the metrics that are the most meaningful to you.

Right now, it's integrated with Github, but I'd love to talk to more people about the tool before opening it up. Let me know what you think!

That advantage is going away as health networks are allowed to slurp up all of the doctors.

Where I live, 95% of medical practices belong to 2 networks. Step two after consolidation is reduce costs. Long story short, if you don’t have cancer, you’re looking at 90+ days for an appointment.

Dermatologists are a little different in that they can make money selling bullshit spa services. So you may see more variance by region as being cut out of hospital networks isn’t as big of a deal.
At the Federal level, it is more useful to talk about net taxes of all types. That is, taxes of all types paid to the Federal government (income, excise, payroll/social, etc) after subtracting all transfers and distributions to the taxpayer. This is a more accurate accounting of the situation. It paints a slightly different picture, but not that different.

It turns out that only about 20% of taxpayers send more money to the government than they receive in aggregate across all forms of taxation and transfers. Another 20% of taxpayers roughly pay their own way, providing about as much tax revenue as they receive in transfers. 60% of taxpayers receive more in transfer payments and other distributions than they pay in taxes (not that surprising with things like Social Security).

tl;dr: across all Federal taxes and transfer payments taken as net, 20% of taxpayers are paying taxes that are transferred to 60% of taxpayers.

Individual States have diverse taxation structures, so the net taxpayer statistics likely vary widely.
For real this is almost unusable. Would be curious to see what's going on here, the rest of this tool looks well-designed.

Following logic like this is why so many aspiring entrepreneurs don't have more paying customers, and it's _the_ source of ad-supported everything.

Want a healthy online economy of individual consumers that isn't bifurcated between people who might pay because it's related to their one main hobby/business vs the masses who do everything else on Facebook and YouTube? Then let them have a way to give you 20 bucks for what they would have consumed over the next year on your free tier.

Instead of letting me give you 20 bucks one time to try something that looks interesting, which is an easy decision to make, you demand that your customer base divide themselves between casual users who will never leave the forever free tier because your prices won't let them and your billing plan immediately† brings to mind thoughts about the overhead of trying to cancel something that turns out not to be worth the price tag, vs wantrepreneurs who can rationalize a recurring expense at the same price as a year of Amazon Prime because they see it as the cost of doing business since they "know" they're eventually going to win the startup lottery.

† Autopay availability should feel like an easter egg that people can seek out and enable and get a sense of satisfaction from because it makes them feel productive. If you're handling it in a way that makes it a source of anxiety, then you're fucking up. Don't look around and say "everyone else is doing it". If there's a known problem (like "it's really hard converting people into paying customers" is a problem) and everyone else is doing the same thing, that's your signal to not do that thing. (How do so many aspiring capitalists not get this?)

> low out of pocket costs.

Are you factoring in premiums? Once you factor premiums from both sides (employer and employee), healthcare in the USA is far from low out-of-pocket. Good family coverage is on the order of $2,000 or so a month.

That's not even getting into the garbage plans offered at some places. I've had plans that covered visits to exactly one region hospital system, any other hospitals needed preauthorization, and even those had the potential for rejected claims.

Which brings up another often missed point. When dealing with the lower cost plans, there's a huge risk of having a claim denied. I know for a fact that at least one major insurance provider has a policy to deny every claim and make the hospital rejustify it. If the hospital fails to justify the claim (to the insurance company standards), either the hospital system has to eat the cost, or they bill the patient instead. This is used to get around those "out-of-pocket maximums" cheap insurance is sold on. So you may only have to pay the first $8,000 of the bill, but that only applies to the first $8,000 of what the insurance company agrees is covered.
The report says that the % of people(tax units) who didn't pay either in 2020 was 20.5%.

The 43.3% was the % of tax units that had a net negative income and payroll taxes (thought I doubt this included the employer side of the tax which for economics purposes falls on the worker). But that was also the Covid year.

Most years it's 25%-22%, which doesn't seem high for the poor, the disabled, and the retired.

There's also reginal variability in this.

My experience with a dermatologist (in the US) ended up being the same as you anticipated it being. Trying to book a new patient appointment myself I was getting quoted availability 2-3 months out.

I was able to get that sped up a bit by having my primary doctor refer me (which my insurance didn't require) and set up the appointment on my behalf. But even then, it ended up being almost 6 weeks out.

I've also had to book GI appointments in a few different locations, and have had some get me in within a week and others that had a multi-month wait.

And some insurance plans in the use are HMO plans[1], which generally have the requirement of going through your primary care doctor for everything and requiring a referral from them to see other physicians.

The biggest gripe I have about the US healthcare system is how impacted it is by employer decisions. Having decent coverage today doesn't mean the coverage will stay decent, even if you stay with the same employer. I've had awesome insurance unexpected swapped out for crap insurance due to an acquisition, had good plans that I took into account when determining whether to take a job disappear the year after during open enrollment season, had the "same" plan change year to year in subtle but impactful ways (like keeping per-person deductibles the same, but adding a condition to meet a minimum family-level deductible in addition to any individual before you actually hit the threshold).

Sorry, not Hauerwas, Lesslie Newbign, probably in his Foolishness of the Greeks from '86, but I suspect he wrote earlier on the topic as well. See: https://www.pastortheologians.com/articles/2020/10/28/politi...
I thought he owned over 19% from the get go before any awards.

I also read he was getting the equivalent of near 1% of the company’s total stock in the first or second award

> he is getting paid 10% of the market cap in a year

So is my previous statement incorrect? Where is he getting $60-90B in a year from?

Here is a link listing his awards so far:

https://observer.com/2020/10/elon-musk-tesla-performance-bon...

It adds up to a bit under $9B when the market cap was more than 2x lower. We are still talking about around 3% of the market cap.

—-

If you mean to say he will get 10% if he meets every tranche. I don’t see why that is such a big deal. Tesla’s absurd market cap is where it is because of him.

> loans..$69bn

Is there any source for this? This seems incredibly insane. A couple billion in loans makes perfect sense. Why would he even want double digit billion dollar loans?
Whenever I see stats like this that don't account for age, I ignore them. They are worthless.

It compares a recent Stanford grad from a wealthy family to a 55-year-old who was scraping through the first 35-40 years of life, but now makes $190k/yr as a successful tradesman during boom time. The former will count as "poor" and the latter will count as "top 10%".

In other words, no, it's not comparing Americans of different classes. It's comparing Americans at different stages of life. Or just the ebb and flow of income over and individual's life (selling a house even in a modest area can easily put you into the top 10% for a year).

You need to follow individuals over their lives to get a better picture of who is struggling and who is thriving.

Governments should be forced to choose between collecting income taxes _or_ taxing everyone through the general monetary inflation (a.k.a. money printing). They currently practice both - the income tax taxes the non-rich, and the inflation also only taxes the non-rich, because the freshly-printed money goes to the rich.
As someone who wrote a post on tempering expectations with GPT-3 (https://news.ycombinator.com/item?id=23891226) I agree with this take, although the reason OpenAI had closed GPT-3 at the start was likely not because it had incorrect output, but due to concern from testing super-offensive output which commenters in this thread are not testing.

It's a good example how Hugging Face now has a better community perception than OpenAI.
That is a good point, but I believe that those programs did not add much to the recovery. They helped but not as much as commonly assumed. Rather, look how much profits multinationals generated. I think it had more to do with increased productivity and efficiency. Much of the stimulus was spent on administrative stuff, paying down debts, or saved, as opposed to consumer spending.
I think it would complement, not replace. There are missions that nicely fit the capabilities of UAS, there are missions that nicely fit the capability of satellites, and there are in-between missions that could benefit from long-duration aircraft like this. I live in the east side of Washington DC. We regularly have police helos flying overhead. I wonder if this kind of platform could supplement their efforts for things like tracking escaping vehicles when the police call off pursuit (car chases are frowned upon here due to the fact that they're so dangerous).
