This is normal. Confirming hits gives your enemy valuable information about their accuracy.

I'm going to go with a "lol, Iran doesn't have access to Russian and Chinese state-based and public satellite imagery?"

Sure, "this is fine."


Why is it assumed that they cannot get that information in other ways? If only they had an ally with satellite imaging capabilities that have a vested interest in seeing the US struggle. Sure, they can tune into CNN and see what's being said there too, but to assume that's their sole source of information is just farcical.

Iran reportedly bought[1] a TEE-01B satellite from China in 2024, giving them quite detailed images directly with ~half meter (~1.7 feet) resolution[2]. Granted they reportedly also got help from Chinese ground stations.

So they could probably just check themselves how it was going, unless they wanted rapid feedback I suppose.

There's a limit to how many photos you can take with somebody else's satellite. Even if the russkies are complying with every Iranian request, that would at least serve to deny russia the ability to use their own surveillance resources to their fullest potential.

Don't satellites have very limited abilities to change their orbits? A request for Iran would be for Russia to photograph something when the Russian satellite is in the area anyway. Unless Russia happened to want to concentrate on something else in that area this shouldn't impede their own surveillance.

Also, I'd expect that everything Iran wants to see Russia also wants to see.


At this point, China would be interested as well. If Xi decides to get on the despot raiding party bus, he'd like to know how effective Iran's capabilities have been on US assets. At this point, North Korea might be looking south too.

Huh? Satellites follow fixed orbits, they don't get moved around to fly over a specific location. They can take images of everything they pass over.

Not everything at once. The lens needs to be angled.

If only other countries just gave away their sovereignty then we wouldn't have to preemptively take away their sovereignty because if we don't then they will do it to us. If we don't instigate war then it will come to us and our stocks won't go up and contracts dry up.

This allegedly ally has likely considered all the potential advantages and disadvantages and is acting accordingly. Sometimes the smartest move one can make is no move at all.

how's that working out in Ukraine?

What do you mean by "that?"

that = "no move at all"

You seem very confused. Who are you referring to as having made ‘no move’ in Ukraine?

There’s always a tension in democratic societies, however, where civilian oversight is important. Claiming the war is going really well until asking for $200,000,000,0000 because it isn’t has little military benefit compared to the political ramifications of preventing public oversight.

We learned from WikiLeaks that the US government classified (hid) significant information that was not relevant to national security, simply to conceal information about the war effort that would likely have turned public opinion against the war.

That is a clear abuse of power, which like most of the abuses revealed by Wikileaks, Snowden, etc., get solid bipartisan support.


It’s not 1943. They know they hit.

And so does every satellite operator.

Iran currently has tasking control of a single Chinese military spy satellite with sub meter resolution. They struck this arrangement before the war. This capability has provided them targeting/tasking info as well as post attack BDA capabilities.

The delay on commercial imagery purchase isn't to hinder Iran, it's to hinder our understanding of the conflict.


Yes, Iran's tactic is to take as many hostages as they can and then vilifying their opponent. Denying or just resisting that tactic, obviously, means denying as much of this as possible, while keeping general correct information about the conflict available.

Americans have a very low tolerance for the true cost of war (which I think is probably a good thing when they’re in the aggressor role).

The full truth of the situation going public is probably one of few ways to pull back on this unchecked government behaviour, given Congress seems all but dead.


>unchecked government behaviour //

It's not "government behaviour", it's unchecked dictator's behaviour. It's not democratic, and the former service personnel who are doing it know they're contravening the constitution, committing war crimes, and so breaking their vows and promises. And all seemingly to just be a lever for Trump and his cronies to pull on to steal multi-generational wealth from everyone invested in USA markets; to add to the multi-generational wealth they're stealing via contracts and just taking as bribes, clear as day, right under the noses of congress.

USAians who support Trump seemed to tolerate his militia and the former USA army being used against your own citizens, and tolerate war-crimes that are written as the definition of the types of orders that soldiers must refuse to carry out.

I wonder how long it took the provinces of Rome to realise Rome had fallen.


One thing I do not understand is the sheer ridiculousness of the participation rate within the military. As you stated, many of these people in positions of command know exactly what they're violating, be it domestic law, international law, standards of decency, or their own morals. Enough of them seem to disagree with the current directions being given that they could refuse orders and draw down, effectively paralyzing the military with a sizable non-compliant command structure. And if they're all removed from their posts the ensuing chaos would ensure the implosion of the current operation and likely cripple the military for decades. There's a very powerful position these people are in, and they know as much. What's even more important from this entire interaction is that they stand to lose more than they would gain from continuing the war, while they would gain nothing but lose very little if they just stopped and refused. The continuation is actively detrimental to the military because it increases fear of petty or capricious reprisal, reduces trust, makes international cooperation during crises less likely, and pushes foreign militaries away from buying U.S. equipment.

So why continue listening to the order to punch the brick wall and break their knuckles? There's some deeper cultural issue at play here, likely that's been there since Vietnam and only grown over the last sixty years, where refusal of orders even if clearly detrimental is a betrayal of your country and fellow servicemen rather than an exercise in judgement and consideration of consequences.


> USAians

Americans. Please avoid this childish demonym unless you're going to commit to calling people from South African "SAians" too.


This is nonsense, they have the same information as everyone else right? Iran knows because Russia knows. Even the private sector has satellites. There is no secret.

Iran already has confirmation from Chinese satellites

It also gives them propaganda wins.

To me the propaganda win would be showing Hegseth saying the US is doing really well and not acknowledging losses while showing all of the damage the US has sustained. In this day and age, only the die hard loyal MAGA followers are unwilling to accept these bald-faced lies, and even their eagerness is waning.

Sigh, there would be no need for propaganda wins or worrying about enemy learning about their accuracy level if this elective war did not take place at all.

But none of it is a surprise, is it? Iran was on the list for a while now and last time I mentioned it on this forum, I was laughed, because "it didn't happen yet" either missing the concerted effort to make it happen or being part of the deflection campaign.


"This is actually good news for the US."

those satellite images are from the "enemy" lol

> Orion utilizes two Vehicle Management Computers, each containing two Flight Control Modules, for a total of four FCMs. But the redundancy goes even deeper: each FCM consists of a self-checking pair of processors.

Who sits down and determines that 8 is the correct number? Why not 4? Or 2? Or 16 or 32?


They probably set an acceptable total loss rate for the mission and worked backwards to determine how many replicas of each system they need to achieve that while minimizing total cost/weight.

So the answer is "some engineers sat down after talking to management".


This is correct.

Eight shall be the number thou shalt count, and the number of the counting shall be eight. Nine shalt thou not count, neither count thou seven, excepting that thou then proceed to eight.

Ten is right out!

Given a list of estimates of failure probabilities, finding the right mix of redundancy becomes a very tractable problem, maybe even freshman-level.

Getting the probabilities could be very difficult though, especially for issues that never occurred before.

The fault tolerance is mostly focused on background radiation flipping bits. We've got half a century of data on the frequency of those upsets and the extent to which they're correlated under different space conditions for that, not to mention the ability to irradiate prototypes of the flight computer with representative amounts of shielding in ground based facilities...

For issues that have never occurred before, probabilities are the wrong tool. The right thing to do is list all the behaviour the vehicle must never exhibit and think of ways it still might, despite all redundancies -- maybe even despite every single component working as intended.

Lots of mission failures in history were caused by unexpected interactions between fully functional components. Probabilities of failures don't help with that.


And why you test till failure (ideally under real/similar conditions): to surface the failures that have never occurred before, and start collecting data on them.

That is what you hire an army of engineers for.

Why use an even number? If they use a voting style consensus mechanism wouldn't an odd number make more sense?

Once you've lost more than ~2 processors, you're probably into the realm of common mode failures and voting won't save you. At that point, it's entirely possible you're just working with random data coming out of all your processors.

Only in that it's in a private equity fund, not one-time spending.

If this is run anything like the CPP, it will underperform both the market and their own benchmarks yet lead to executives awarding themselves huge bonuses.

Over the last decade (and even prior to that) CPPIB has been the best performing fund of its kind. National pension funds have different risk tolerances and investment guidelines that someone's personal portfolio or a family office.

Thanks to CPPIB, Canada does not have have a giant unfunded pension liability (unlike our neighbors to the south). It has been an enormous success story.


Yes, far better than how the UK runs its state pension system.

The Australians seem to have the best model overall though. Mandatory payments in to private investments has made them very wealthy.

The UK system takes the national insurance contributions of workers but doesn’t invest them in anything on behalf of the individual. So despite decades of payments you technically have nothing at the end and survive on the goodwill of the government and current taxpayers. That works right now because of the population pyramid.

Canada definitely has a better system than that.


>The UK system takes the national insurance contributions of workers but doesn’t invest them in anything on behalf of the individual.

That's how Social Security works in the United States as well.


I believe it’s tied to your earnings in the US though, which it isn’t in the UK.

I also have a number of qualifying years in the UK when I didn’t work, and for decades you could buy a year contribution for about £150. The payout is £12,500 per year.


>That works right now because of the population pyramid.

Is it really a pyramid if the base is less wide than the top? I guess it would be an upside down pyramid, but not very useful for the intended purpose then.

I thought that honour belonged to the NZ super fund with an annualised return of 10% before tax since it's creation in 2003. I couldn't find a comparable figure for the CPPIB, but it looks to be lower.

https://nzsuperfund.nz/


That seems fine as long as they can show lower volatility than market while still being close in return?

Did they?


Why does it matter if volatility is lower than the market?

Future payments in the short term are covered by inflows.

You might as well maximize the returns now so that in the future when it's not covered by inflows you've acrewed a larger return.


> Why does it matter if volatility is lower than the market?

Because I can trivially beat the market by ~100% by going long on 3:1 margin.

The volatility is why that's a bad idea. One time out of five, the consequence of that investment strategy is 'The market had a crash and I lose everything'.

'Lol, YOLO' is not a great investment strategy for a well-ran country.


> One time out of five, the consequence of that investment strategy is 'The market had a crash and I lose everything'.

Which is why that strategy doesn't actually beat the market. Keep using it for 30 years and you're bankrupt.

Whereas if you put your money in a major index 30 years ago and left it there, or even 50 or more years ago, what result? Are you even in a bad place if you put all your money into the market in 1926 and left it there for 100 years?


Yes, if a retirement fund had put all their money into a stock index in 1926, it wouldn’t have been able to pay out pensions throughout the 1930s and 1940s and would have been bankrupt before the market eventually recovered.

Going full index is a great strategy for an individual person aged 20-50, but not a strategy for a pension fund which needs to continuously pay out.


> Going full index is a great strategy for an individual person aged 20-50, but not a strategy for a pension fund which needs to continuously pay out.

It's OK for a person in their 70s that has a few million in the bank.

This person (CPPIB) has 780 billion and has a sustainability rating for 75 years.


$780 billion divided by 6 million current recipients is a little over $100,000, which is hardly comparable to your wealth retiree example.

Did you realize that CPP's support isn't full income replacement? It's only 10-20k/year per person.

While your metric is common to compare pensions, it's not relevant for debunking ability to survive a recession.

6 million x $100k is 600 billion.

Whereas the annual benefits paid is ONLY 1/10th that at 60 billion/year.

Turn off 80 billion/year in contributions and the investment income (50-60 billion/year) can sustain.


During the Great Depression, the stock market stayed below 50% of its peak value for about 20 years. Imagine that the $600 billion turns into $300 billion overnight. It will only last 5-10 years without inflows, but the GDP has also dropped by 40% and inflows have plummeted.

I saw you say this in another comment.

It's still going back to the same assumptions that you're not only timing a depression but also

(a) don't have pre-funding (i.e., millions for an individual at the start of the depression),

(b) don't have CPPIB guardrails and auto-adjustment mechanisms,

(c) and it's not a partial income replacement scheme.

> It will only last 5-10 years without inflows

Without inflows? That's not realistic because people would still be contributing. In fact, CPPIB has triannual resets of contributions and in a recession, they'd up the contribution rate. In a recent actuarial audit, they found that if real returns dropped to 2.5%, then they'd only need to boost contributions from 9% to 11% to keep their 75-year sustainability target.

The advice that you need to taper off your investment portfolio risk as you get older doesn't really apply to people that have a nest egg. I know a lot of people that aren't necessarily living frugally and are told by their financial advisors that they might as well upgrade their cars, travel more, etc. They can cover their costs and don't have net worth > ~$3 million.


I have no idea what you’re talking about at this point. Do you have any interest in understanding why CPPIB invests the way they do and doesn’t seek the highest returns?

You know you're not being fair with that take.

Clearly, I am aware of the CPPIB's structure even citing the Office of Chief Actuary's report regarding downside scenarios and health scores. [0]

edit:

> if a retirement fund had put all their money into a stock index in 1926, it wouldn’t have been able to pay out pensions throughout the 1930s and 1940s

Point was that this/your rationale doesn't apply to CPPIB's situation.


> Future payments in the short term are covered by inflows.

That wouldn’t work in a major depression when there is high unemployment and inflows drop.


Well, it could absorb it because its horizon is past the depression.

Let's not forget, CPPIB underperformed a passive benchmark during the Great Financial Crisis and lost 18.8% in FY09.


> Future payments in the short term are covered by inflows.

is that similar to the Ponzi scheme pattern, though?


Ponzi schemes always make current payments out of current inflows. The first 10 people get paid from the inflows from the next 100 people who get paid from the next 1000 people and so on, until you run out of people to sign up and the last group is left holding the bag. This is how Social Security works in the US because it started out by making payments to people who never paid in and was premised on the early 20th century fertility rate of >3.5 instead of the current ~1.6 to keep the system from collapsing, which is why the "trust fund" is running out of money -- it never had enough to cover future payments to begin with.

Whereas having individual years when the fund pays out more than it collected in interest is not a problem as long as that's not what happens on average.


kudos for a thoughtful and clear explanation: useful indeed as my question was genuine, not snarky.


This youtuber appears to be anti-active management. CPPIB is underperforming their own benchmarks and charging substantial active fees.

> Where 20 years ago the CPPIB had just 150 employees and total costs of $118-million, it now has more than 2,100 employees and total expenses (not including taxes or financing costs) in excess of $6-billion.

But...they don't appear to be terrible v. their peers, but that might be an indictment of pension funds.


"We achieved superior risk-adjusted returns" as an excuse for sovereign fund underperformance is nonsense. PE (depending on how levered it is) inherently has lower volatility than buying public stocks.

If your fund gets consistently lower returns than if you had just stuck everything in a 60/40 portfolio, the whole endeavor has failed.


I really like the ideal of just chucking it all in VTI (or, since it's Canada, some other equivalent). But does it still work at that scale? Or does the fund exert its own gravitational field on the index in question?

The gravitational field of indexes that large is one of the reasons why it works. The stock price of a company will generally increase when it's added to a major index because there are now so many more people trying to buy it as part of the index.

The risk is nominally that if you ever wanted to move a fund that large into some other investments, the act of selling would lower the price of the assets in the fund. But that's what happens no matter what you invest that amount of money in. But then widely distributed whole-market indexes would tend to mitigate that.

The real problem with this is that it disconnects what people invest in from the fundamentals of the companies. Promising companies don't get as much investment if they're not in an index, and mismanaged companies get too much if they are.


> The gravitational field of indexes that large is one of the reasons why it works

I'm confused because my question was whether a sovereign wealth fund could move an index by too much. Not about the issues with index investing (which IMO are mostly overblown).


Not Canada, but Bank of Japan and the equivalent JP pension fund have juiced the crap out of domestic JP stocks with ETF purchases.

In contrast, the PSPF (federal public sector pension) has over-performed.

different risk profile

They've underperformed their risk-adjusted benchmarks.

> But the CPP fund didn’t just underperform the indexes last year. It has done so, on average, ever since it switched to active management. That’s the admission you find buried on page 41 (it was on page 39 last year): since fiscal 2007, “the Fund generated an annualized value added of negative 0.2 per cent.” Compound that 0.2 per cent annual shortfall over 19 years, and it adds up to more than $70-billion in forgone income, on assets that now total $714-billion.

> The cost of passenger rail is high in America, because America doesn't build enough rail.

The cost of passenger rail is high in America because America has 11% of the population (read: customer) density of Japan.

(For cities, NYC has 25% lower population density than Tokyo.)


Dividing population by total land area is a horribly misleading way to understand density. There are alternatives, like population-weighted density, that give you a better picture: https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3119965 Here's a blog post where somebody re-invented the concept and analyzed density in Europe: https://theconversation.com/think-your-country-is-crowded-th...

The population-weighted density of the US is roughly similar to continental Europe.


There's this one neat trick where you only build the rail where the people go!


The first link you posted says that 29% of the land is used for pasture and 15% is used for crops (which will include both human and animal).

So yes, most cows are eating grass like a wandering herd.


The data doesn't prove either point. For all we know, a very low number of cattle are being grazed on those 29%. Or a lot of them. We don't know.


That doesn't follow. The chart is counting the number of acres of land which are used for specific purposes, not the number of cattle being raised on that land. And the category you're counting as "pasture" encompasses rangeland as well, which is used at an extremely low density (often as low as 1 head of cattle per 10 acres).


> To feed a growing population, it is essential that the global agri-food system be managed to efficiently convert crop production into calories for human consumption.

It's really not. Efficiency is the enemy of redundancy. Countries want food security, so they must therefore produce excess calories.


It’s really, really not. Crop land per capita has been going down for decades despite richer diets, and all the biofuels and livestock feed [1]. Let’s not forget that advanced drugs to stop people from overeating the abundant food are a $60 billion and rapidly growing market.

[1] https://ourworldindata.org/grapher/cropland-per-person-over-...


I think it's important to a point, to be pedantic. But yes, global food production is well over the hurdle of production volume to "feed everyone", even for highly redundant crop yields. The remaining challenge is purely logistical and of course combating unchecked profit motive that's become malignant.


Global food production now produces more than enough calories to feed everyone, but still hasn't figured out how to produce enough nutrients to feed everyone.


I'm not really sure that holds. Carb-heavy grains form the bulk of global food production, but meats, legumes, fruits, etc. are still massively overproduced. Of course, I think you get at something very important to recognize which is that modern industrial variants of vegetables/fruits are bred in favor of crop yield, size, shelf-stability and visual appeal/consistency. Many of those contribute to lower nutrient densities.

I don't think it matters as far as getting enough micronutrients is concerned, but speaking from a lot of experience, "heirloom" produce is absolutely superior in terms of texture and flavor. It's not even close. I think we could really stand to put more effort into making robust food supply chains without turning everything into bland mush.


If you ignore waste then it is likely that we also produce enough nutrients. That isn't a useful way to look at it, however, as, just with all things in life, losses are inherit. A 100% efficient system will never exist. Calories, though, we produce enough of even accounting for all the waste.


Well, the Moon, Sun, and Earth are all flatter than most surfaces in my house, and I call those surfaces flat, so yeah...


1.8kg of common food is 5000 Calories-ish. I can only imagine that dried food is more calories per weight. So yeah, a lot.


> So all of a sudden the nice town clinic has $2,500,000 in debt, raise prices accordingly...

From a financial engineering perspective this is wrong.

Both equity and debt have costs of capital. Debtholders expect interest, capital holders expect RoE. The money going to debt interest is money that would previously have gone to equity, but now does not because the equity is replaced with debt.

Crucially, the costs of debt is lower than the cost of equity because of the interest tax shield. Therefore, the vet clinic now requires less revenue to maintain or even increase its return to equity.


Technically true, but RoE expectations from a PE firm are typically a lot higher than from the original owners of a small business.

And the LBO model is much less resilient to economic headwind. Let's assume a 25% EBITDA margin business, with most costs fixed (like the clinic example). Unfortunately revenue drops 20% because of external factors. It would maybe have a tiny profit left, tax would also be tiny and there is no interest to pay. The shareholders receive near zero, absorbing most of the problem for a year waiting for times to get better.

Now the same business, same reported EBITDA, but paying a large interest sum every year to the bank. If revenue drops 20% they can't pay their interest, and banks don't just wait for next year. Now the business has the restructure, agree with the banks what that looks like, or face a bankruptcy risk.

While the new PE shareholder has a better RoE due to leverage in the upside scenario, the business (and the PE) could be completely cooked in a downside scenario. For the PE this is a calculated risk, they optimise the overall portfolio. But for the employees and customers this isn't a great scenario.


> the vet clinic now requires less revenue to maintain or even increase its return to equity

The small-town vet would have probably accepted a lower RoE. More critically, they’d have been more willing to absorb shocks to said RoE than a lender will to their debt payments.


Small businesses are notoriously bad about calculating RoE; bookstores that own a building that would rent for way more than they ever make in a month, etc.
