I get thinking phones were to small of a market or margins were too thin back then. But you would think when the smart phone market got bigger and prices went up someone would have re-evaluated that decision.
Great insight.

Additionally, an attacker could gain long-term visibility of the cameras footage, simply by continuously capturing the broadcasted keys via a covertly placed device, either in close proximity to the camera or further away with high-gain directional antennas.
But that isn't what the term means. If your product isn't yet viable, you don't have an MVP. Being able to silver-tongue your way to clients doesn't change that.
I think the point here is that your MVP should behave like the actual product in the eyes of the customer, but you do not have to actually build the functionality. By providing a lot of the service manually, you can get your initial customers quickly. Having customers means getting feedback from the product's target audience. Getting this feedback before actually heavily investing in automating the product means when you do automate, you have a much better idea of what the final product should look like and which features you should prioritize, wasting less time and money on building the wrong things.
> The Fed is buying assets at a premium (otherwise counterparties wouldn't sell the assets to the Fed)

That's not necessarily true, economic transactions aren't necessarily zero-sum. I would assume for most of the assets being sold to the Fed, the banks need liquid cash more than they need the asset and so would be willing to take a haircut.

>The only way this ends is either a depression the scales of which we've never seen in history before[...], or a hyperinflationary collapse of the U.S. dollar

Why specifically do you think this will happen now when it didn't happen post 2008? Sure the scale so far seems bigger, but also the scale of the hit the "real" economy is taking is much bigger. And, in March, when some of these asset purchases had already started, CPI declined by 0.4%.
why is that hard to believe? It's clear that many (most) experience no symptoms, and if the size of the infected population doubles every ~3 days, well, you do the math...

This will work out fine until it doesn't. At that point, the US will face many "bad or worse" kinds of choices. It will be like the choice we face today: "close the economy or the morgues start overflowing everywhere." Except it will be every day, more or less forever. Inject still more money into the economy or the entire financial system collapses.

Whenever this balance sheet chart shows up, MMT boosters descend to explain why the Fed's balance sheet doesn't matter. It's interest we owe ourselves. Nobody in the real economy looks at that balance sheet when making actual financial decisions, they claim.

I think that misses the point. The point is that since the last financial crisis, the balance sheet has on net expanded. By a lot. When the current crisis hit, the balance sheet shot up from an already elevated level.

To put it another way, consider the size of the balance sheet relative to GDP (~$24 trillion):

https://fred.stlouisfed.org/series/GDP

At the current level, the balance sheet is about 25% of GDP. There's every reason to believe the Fed is far from done. It's bailouts as far as the eye can see at the moment. And those bailouts will be monetized by the Fed. We can't possibly pay for them at the current value of the dollar. Ever.

To the MMT boosters, what happens when the balance sheet approaches 1x GDP? 2x? 5x?

Nobody knows because this experiment has never been tried before. The reserve currency printer is also a net debtor. It runs very high, structural deficits with no end in sight. The currency is completely decoupled from gold, and as recent history shows, possibly industrially-critical commodities like oil.

I'd be very curious to hear from the MMT proponents on what signals they's look for that the Fed's balance sheet actually does matter in the real economy. Things that can only be explained by problems stemming from the size of that balance sheet. Problems whose only cure is a massive reduction in that balance sheet.

Of course, the balance sheet isn't going anywhere. Nor are deficits. When faced with such situations in the past, the answer has been devaluation.

The US did that back in the 70s when it closed the gold window. It will happen again. What the MMT proponents I've seen seem to ignore is what form that devaluation will take given the highly unusual circumstances around which it will be occurring.
Agreed, that would be even better. I wonder what happened to GitHub that their entire HA system didn't work.
Ask HN: Learning DSP witha software development background?
I notice that DSP is something normal taught in an electrical engineering background, however I see it in job listings for lower level software development roles.

I'm a software develope, both professionally and as a hobbyist for years. I have no formal education whatsoever, and am weak on mathematics, especially in subjects you would find in an engineering program as prerequisites to signals courses.

Is there a good way for someone with a software background to learn DSP, like a course taking that background into consideration? Would I have to work through the full equivalent of the math taught in a university setting? I don't mind paying for something as long as it's not several thousand dollars, but I dobt want to purchase something and realize in way over my head with no hope.
People also forget that Intel had a pretty decent line of ARM CPUs right before the time the iPhone was released (XScale). And they gave up on those too, just in time for the market for smartphone CPUs to explode.

It limits the rate at which you can dump energy without excessive temperature excursions.

Can you describe a little better what this box's purpose would be (scenarios most relevant to the development becoming a commercial success), because a cursory glance at the real-time audio part of Max/MSP (and the Pd (Pure Data) fork/clone) suggests that specialized audio DSP hardware would not be beneficial, compared to using a CPU/distributing it over multiple cores, or potentially even a GPU.

A monoid is an algebraic data structure that has a binary operation (+, *, ++, etc), and an empty element (0, 1, [], etc). In terms of relationship to other algebraic data structure, it "inherits" the binary operation from its Semigroup buddy, which is a very nice data structure to represent non-empty containers (and statically enforce that property).

Well, first, I suspect that Keynes would be ashamed of what post-keynesians have made of his insights.

Anyway, you are implying that the current system is Keynesian, and that there are people advocating to change to a MMT system. But the current system is already MMT.

So, to answer your question, for accountability, you could just keep in place the current way of doing things (or find some alternative) but recognize that "taxation and debt issuance are not required to fund spending". Let's recognize that public debt is irrelevant for instance, and that, yes, deficits can be inflationary, if the economy is already in full utilization but could not be in the proper circumstances.

>>" People aren't interested in MMT because it is a neat model; but because if we use that model then it becomes very hard to explain that policies are wasteful uses of time and stuff. It is very easy to make a taxpayer understand why government waste is bad. Quite hard to make people take an interest when nobody knows if they are net givers or takers"

So, basically, what you are saying is "let's lie to people" so we can have a smaller government.

They say that naming is one of the hard things of computer science, maybe it's also true for economics. Let's change the name "public debt" for "public investment" and discuss then how much public investment can we afford.

I had the same question a few weeks ago! Apparently, the delay between monetary stimulus and the time we'd notice inflation is estimated to be greater than 12 months. I found one of the sources whose abstract I scanned when I had this question[0].

Hedge: I'm not saying it's true or that I've verified any of the research, only saying that economists have studied the effects of central bank stimulus action on inflation rates and the economic response seems to take a while.

I’m pretty impressed with the depth of field the Quest is able to develop in Passthrough+ mode just using the 4 wide field tracking cameras and a smartphone processor from 3 years ago. A residual, after-thought capability like that on a $400 device is pretty impressive, IMHO.
actually that seems to be the default method of counting deaths. I find it questionable to attribute (100% of) a death to covid when 4 other conditions existed and contributed to the fatality but there you have it. The undercounting issue has been a result of deaths of untested patients, e.g people found dead at home in NY.

Belgium on the other hand reports all deaths that could plausibly be covid related.
I for one cannot wait for an ARM Macbook! Might be some pain early, but in the long run it will be great for laptops and computers in general.
What's a little confusing is that they are not testing the same versions of the software but (presumably) the distro default version. So these benchmarks are not useful to test kernel and lower level performance differences.
Too much software mindset. You can build a no-code solution, see how potential users interact with it, and learn from that. You can gage interest just by presenting something to a focus group in a somewhat interactive way. MVP could even just be a poll. No need for a "product" or even a demo.

If you can build a prototype fast and deliver fast, that could be valuable, but is often waay before evaluating what to build in the first place. There are success stories building something and iterating on that. If you yourself is multi-talented, have the time, clout and love your software, there might be some odds others might like/need it too. The latter is associated with most failures though.

So be a business, not a software delivery function.

Complexity guarantees for algorithms are often expressed explicitly in numbers of operations, not time [1].

Edit: actually, nth_element is a great example here:
https://eel.is/c++draft/alg.nth.element#5

The complexity requirements for container member functions are often more vague an implicit, but I believe those are also not expressed in terms of time either. It's some other implicitly implied operation. In [2] for example this operation is the construction of a single object.

An other tangentially related part of C++ is <chrono>, but I do not think that there are strict requirements there for precision. At most there is monotonic requirement for steady_clock[3].

Just to make sure I understand what you're saying, let me try to think of an example.

A number of AI companies start out by outsourcing the "AI" to something like Amazon Turk or remote contractors. From the customer perspective, the system is working as intended. The system transcribes their videos, or schedules their appointment, or whatever.

In the backend, the system doesn't exist. It's just a bunch of people manually transcribing videos and manually creating Calendar links. And those companies are validating that customers will want to use the fake version before they spend the time building an AI-driven real version.

Do I understand correctly, or is that different from what you were trying to say?

But in that case, you're still building a product that does a thing. It's just that the product doesn't currently scale, and the business isn't being up-front telling any of its customers what they're actually buying. I wouldn't say you built a mockup in that situation, I would say you built a call-center, and you're thinking about whether or not to automate it based on demand.

This really resonated with me. Distributed systems are _hard_ and tests (while valuable) are no substitute for being able to reason about what your application is doing and what might be affecting it.

In Chromium we do have integration tests for the sandbox functionality as a whole and unit testing but it doesn't cover things like this as we're testing Chromium's ability to sandbox not whether the OS's primitives have broken. We might notice if all of a sudden our sandbox stopped working, but for something which only exhibits a problem when it's being actively circumvented we won't.

I can't speak to what MS do testing wise, considering the age of some of this code it seems likely there's no test for this specific functionality otherwise you'd assume it would have been noticed. Testing for security defects is inherently difficult anyway, especially logical flaws where you don't get a nice crash. This case is different but in general you usually need some specific setup process to get the system into a vulnerable state which is hard to achieve without knowing ahead of time the bug you were trying to detect.

Hi,

I built CollabUML after the need to work on designing systems with my peers,
instead of screensharing, it's simpler to go into a website and start collaborating,
it saves bandwidth which can be a problem sometimes, and it allows your peers to do
edits instead of just telling you want to modify.

After thinking a bit and talking with people, looks like it can be useful for system design interviews.

I'm still thinking how to evolve it, if you have any ideas, let me know.

Be aware that anyone can go to any board, hence, avoid placing private information.

Thanks.
It fundamentally doesn't do what UIs need it to. That's why most web UI frameworks use a 'VDOM'. When a framework finds a clever way to avoid doing this (Svelte), we all applaud the accomplishment. I think that gives us our answer. </snark>
OK, not everyones individually, but look at all the major stock exchanges and their value is down. This is a good indicator that the vast majority, and therefore it means that most investors are affected similarly. Are pension funds down? Yes. Are most retail investors down? Yes. Anyone who is up is not up enough to make a difference to the market in general. So dont be disingenous, you know what i meant by 'everyone' in this instance.

I don't think the problem at the current time is inflation - it's deflation. There's less money chasing the same amount of goods and services. That was the case during the Great Depression - and the Fed exacerbated things at that time by not intervening in controlling the money supply because they were bound by rules which prevented them from doing so.

If inflation suddenly increases, then the Fed has tools to combat that. They can sell off some of their balance sheet or raise interest rates to reduce the amount of money in the system. Inflation only occurs because there's too much money chasing goods and services.
