Well, you gain a lot of performance - as much as 10x depending on the complexity of your template. Also, Jinja is a lot less crippled than Django Templates (for example, you can't call a function/method with parameters in Django Templates).
Not that I disagree, but to inject some clarity: Python would be a perfect fit too. The major MTAs are written in C not because they need to be, but because C was the only serious option in the mid-late 1990s. Any modern language would work.

Your use or non-use of public services has no bearing on the amount you must pay in income tax.

Failure to pay taxes is illegal, not theft.

Theft is stealing the property of another. If income is the product of your physical labor, and the state owns your productive output (making tax avoidance theft, as you propose) then you are a slave.

Your source largely agrees with what he said. That is, you must either misappropriate the information or obtain it from a deliberate breach of duty by an insider for the insider's personal benefit.

If you e.g. count trucks leaving a company factory and feel you know nonpublic information about the company's finances as a result, feel free to trade based upon this info.

impl_X is your base class with most of your logic. interface is used to pull out just the parts of the data that you might work with while wanting to have it in SoA format. Then we specialize the vector template for the interface to give us a dummy class with the things we need, but that sends our writes back to the backing array.

If we need to get an individual struct out of it the conversion is automatic. If we just need to access some member vars it will (hopefully) optimize down to direct accesses. We do bear some complexity in implementation, but it's all confined here.

I'm now realizing I was a bit imprecise in my earlier comment. the specialized vector is not around <yourclass> but around an interface parent of your class. You could also just specialize yourclass vector, but then you don't have the ability to switch.
Thanks.

Sorry if I'm being thick, but I'm still having trouble seeing where the pattern for nops is coming from, in this example from the post:

/- eligible
| /- actual
mov rax, [rax] ; 0 0
nop ; 0 0
nop ; 0 0
add rax, 0 ; 1 1
nop ; 0 1
nop ; 1 1 <------ ?
nop ; 0 1
mov rax, [rax] ; 6 6

I would think that the fourth nop is eligible only at cycle 1 because only four uops can start each cycle, but then the fifth nop is also eligible at cycle 4. What's different about the fourth nop from the third and fifth?

sarcher's example of JLC. It does look like a faulty optimizer, which is a DC electronic for each panel.

As for Walmart, it's a lot to unpack.

> dozens showing hazardous problems such as loose wiring and “hot spots” on panels, according to court papers filed in New York State Supreme Court.

Loose wiring? A lot of setups are mostly plug and go. If they had to splice one wire, it's only a minute process to do and if they used their eyes for a few seconds (I'm describing the literal process of splicing a panel wire. I'm not demeaning the work. It's minutes. 3 max, if you brought the parts on the roof.) As for the other connections a solar installation may need, the time it takes it one minute for all connections on the roof. For the 244 panel setup of Walmart, 30 minutes tops (20.3 minutes to be closer to realistic because there might be 21 j-boxes, each connecting 12 panels to the main array).

Hot Spots? I have no idea about that one. It's too vague.

At a different location, this is what Walmart said:
>One of the fires happened months after the system was de-energized, Walmart said.

I don't understand this one at all. Tesla/SolarCity must be using very cheap electronics because this shouldn't happen. Each panel's optimizer should be equipped for the situation when they aren't producing usable power.

Ideas don’t have merit based on the number of parrots.
It seems like "Selecting trusted experts" alone would defer more to human subjectivity and biases than would be necessary if objective measures were utilized as much as possible.

Existing community/expertise based moderation and reputation systems might not be directly transferable or adequate. But it shows there are new ways to think about more decentralized measures of reputation that are new to this century and haven't been tried. New ways that may be preferable to a small group of kingmakers.

I think the biggest problem is leadership and cooperation of community to try something different. It's not just that there is no person who can mandate these things, it's that multiple constituencies have widely diverging interests, i.e. authors, universities, corporations, journals.
I believe this to be false. If the price for gas went to $30/gal in a city in the US there would be tanker trucks, boats, and hotshots with tanks in the bed lining up to get into town. Alternative means of transporting the gas into a disaster area would become economical if the price increases enough. The shortage is created by restricting the free market price.

> If your tax-agents aren’t needed, then downsize them,

I mean, maybe I could have put it more clearly, but I think it is fairly obvious that I wasn’t advocating for what you seem to think.

I’m just not sure what strawman you’re trying to prove wrong here, or who you’re even arguing against. Unlimited funds to tax-agencies is silly, everyone agrees on that, but in both the original and my example, the result of downsizing staff to save a few million on the budget ended up costing society billions.
This is why I love computer science but hate chemistry. Too much volume.
My understanding the primary reason for he developers using custom libraries is not so much performance but a) historically console compilers and expecially standard libraries have been extremely buggy and b) is good to have a single implementation across platforms instead of having to deal with quirks and implementation divergence.

I agree with you completely. I feel that if we rewrite the finance system we'll end up with a different mess. I'm only pointing to a problem not offering a solution.

It's all adhoc design with no theory. If finance consisted of a bunch of axioms and theorems then we could find a algorithm that can optimize such a system.

However finance like software is in the domain of design. As such we construct and create such systems with no quantitative formula for creating better systems or even defining what a better system is... What formula can quantitatively measure how much better capitalism is vs. communism? Or Vice versa. None.

So you, are basically fully correct. A rewrite without formal theory on what is a better "finance" is like throwing darts blind folded. We only know the previous iteration didn't work, and we have no idea if the new design will function. In terms of probability, likely it will be nowhere near the perfection we strive for.
Very interesting theory when it comes to the change in air circulation. But I can't imagine a situation where that would occur unless Walmart's claims are valid on 'poor installation'. The brackets, that hold up the rails, that go into the roof should lock in and shouldn't be any cause for concern.

The underbelly of the panels do run warm but they aren't hot, except in extreme heat. Nor is there any thought to the air circulation when designing a system, since the panels themselves don't have holes in the sides to encourage flow between an array.

Author of the animation here - glad you liked the tool.

I use data published by JPL/NASA HORIZONS interface which provides orbit data for all natural bodies and spacecraft. The "glitch" is because of the data I fetched and used - it has nothing to do with the animation per se.

As of now, the JPL site provides data only until 20th August - the time when I fetched the data a few days back, the data was available until 16th September. This was a "merge" of 3 orbit segments - the Earth bound orbits, the transfer orbit and lunar bound orbits. The former two fit the observed data. The latter was entirely based on predictions. This merged orbit has a discontinuity where the predictions start and that's why there seems to be a glitch.

Once revised data is available from JPL/HORIZONS, I presume the glitch will go away.
Well if you will notice all this framework are abstraction over WSGI or ASGI (these are standards in Python Language interface for web programming). So the situation is not same as PHP.

Moreover if you look at the framework code of many of them you can replace them easily, for example Flask and bottle.py can be completely replaced by your own code if your service or app grows the intended performance. The lowest common denominator in both is WSGI.
I liked a lot of things about qmail, but I found it annoying as a sysadmin, like in the 1.07 days, because you had to do all this patching. I eventually wrote a script that would take all the sources and patches that one needed to run a reasonable mail server, and turn them into an RPM that could be installed, because I couldn't just provide the patched, resulting RPMs.

There were a lot of great things about qmail. I really liked the envdir and how secure it was. But eventually I found the attitude behind it very tiring and switched to Postfix, which is a really great program.

Not really. For the weather model, instead of recording my state as (20,80), I could just store it in memory as (-sqrt(20),sqrt(80))/normalization, with the prescription that to regain probabilities, I must square each entry. The fact that there are negative or complex numbers in the state of a single particle is not concerning. Only when you have entanglement for two or more particles is when something non-classical happens. Please see my other comments under my parents comment.

> No. You are completely and utterly wrong. This is definitive and final.

One of the properties of complex systems [1] is emergent properties; the individuals may be simple but when they interact with other individuals, the overall system exhibits behavior that may no longer be simple due to the permutations and stochasticity. There is a complexity that is inherent. In complex systems, the whole is not the sum of its parts.

Take 2 people who trade with each other (barter). The interaction is fairly simple. Now blow that up to a village. And then to a city. Then to a megacity. And suppose the individuals are more or less autonomous (we call this freedom). And they react to things differently (feedback). And then add randomness and variation. Now you have an complex economy. Then they want to do things bigger than any individual is able to pay for, so the stock market came about. Then add the effect of the environment which can harm many facets of human endeavor, now people want insurance against crop failure, shipwrecks, etc. Now you have derivatives (though arguably the world hobbled along just fine without derivatives for a while).

Complexity in finance like other things has two components: irreducible complexity and reducible complexity. If I had to guess (and I could be wrong), I would say the irreducible complexity part of finance is much bigger than the reducible complexity.

Not to say there isn't any reducible complexity -- exotic derivatives etc. are a product of pure financial engineering and one wonders if we could do without these.

But many parts of the finance system are necessary complexity, or at least necessary to power the modern economy. Else, we'd be stuck in the early agrarian world.

Wharton is the business school of the University of Pennsylvania. He went to business school and got and completed all the same business requirements everyone else has to take. I studied accounting at university along side finance, business administration, supply chain, and economics students. I'm sure there are plenty of schools who offer a degree just called "business," but most people have a specific business degree. I'm looking at the degree requirements right now, it's all the same stuff everyone has to take: marketing, management, logistics, stats, finance. Unless things were really different back then, an economics degree from Wharton is definitely a business degree.
No need to preinitialize the list. When allocating an element you have two cases: a) the free list is non empty: you pop an element by making the head point to its successor; b) the free list is empty: you increase the size of the vector by one.

To deallocate an element you simply set the elemnt next to the whatever is the current head, then make head point to this element.

You start with an empty vector.

An element is either allocated or in a free list, that's why the next pointer can be kept in an union.

Ford got rid of Volvo, Aston Martin, Jaguar, and Land Rover. All of these brands have been doing poorly since Ford sold them.

Ford's relentless pursuit of cost cutting led them to keep many vehicles for far too long. Their former bread-and-butter model, the Ford Explorer, went 9 years in between platform changes. The ford Flex has been on the same platform for 11 years. The Ford Focus went 8 years without a change of platform.

Further, their cost-cutting initiatives have earned many of their vehicles poor reliability marks to such an extent that Ford Focus sales are less than half of what they were in just 4 short years.

I might add that Ford went upscale in price on a lot of its vehicles without an attendant increase in upscale features. The Ford Explorer sells about half of what it used to during its peak.

Selling off car companies was a good idea. However, poor products, poor product planning, poor reliability, and a spineless vision of the future has put them into a bad spot with no real light on the very distant horizon.
This is a news? I thought the Publish or Perish idiom made it obvious.

2 weeks of effort goes into doing something and you spend 2 months of writing a paper of the slightest of the result. Many of these papers introduce an infinitesimal increment to knowledge, at best and you can tell how long would it have taken to get it working. And this is Numerical Mathematics. There are clans of Mathematicians who just go around citing each other. And a quality paper comes around every 5 years or so.
Not at all. Obviously more to it but these are the 2 main reasons I see;

1) Walmart would have a procurement department. These guys probaly have no idea of the likely 1000's of investment companies the Walton family own.

2) As a listed company, Walmart procurement would contact jobs like this to the best offer, not to seperate companies that happen to be owned by shareholders.
