> "How to spot the fake answers put there to fool you" == "how to see when an answer isn't even in the ballpark". That's a useful skill.

It's a probabilistic skill, and in so far as the test is designed to give a measure of what someone knows, and not how lucky they've been, it's gaming the system.

Is it a useful skill? Well, yes. To an extent. So is knowing your addition table, but we expect students to have moved somewhat beyond that by the time they're in secondary education. Just as we'd expect someone educated for five years, six or seven hours a week, 28-40 weeks a year, to have advanced somewhat beyond the need for discarding comedy answers as a viable test strategy.

By secondary level, we'd expect them to know, (or be capable of running the calculation,) to decide among those answers that are actually in the ball park. Approaches for which the cost is more or less constant regardless of how many answers are on the page: You trust your calculation or memory to have given you the answer and discard all others by default.

> But it seems the remedy ought to be "have better tests" instead of "don't test."

Nobody is saying "don't test". The only place that I know of that doesn't test in the traditional sense are Waldorf schools, and even they still evaluate their students.

Concerns are being raised about standardized testing in a NCLB-influenced environment, both in how that limits test design, tests for the wrong things, and how this kind of testing creates the wrong incentives.

> the AP tests have a significant multiple-choice component that resists simple trickery.

It isn't just about trickery. I remember encountering a pumping lemma question during the GRE that was simply easier to answer in multiple choice form because I didn't have to prove the correctness of the right answer, but only the incorrectness of the wrong ones (and even there I didn't have to work out the fiddly details, I just needed a modest amount of confidence).
The fact that price goes down as the application goes from server to desktop to embedded is very telling, in several ways.

One way is the commoditization of computing: actual computer power is now a commodity, with very low prices and standardized interfaces. Ethernet is the new pallet, and servers are trucks.

On the other extreme, the embedded landscape demands catering for each application, demanding a lot of GPIOs, specific hardware and hand work. It gets expensive.

Of course, the Parallella just shows this in such a nice way because it evens the (massive) computing power in all offerings, that differ only in interface. Actual consumer products will try to balance this, but it still tells us a history.
That's the same pie-in-the-sky "what if" that loser corps have been pursuing forever.

1) That's the same kind of half-baked wishful thinking that's been going around the Internet since before the web. 2) I'm not advocating doing what loser corps have been pursuing. I'm advocating flipping the economics around 180 degrees.

someone else breaks it shortly thereafter, whether it's DiVX, or DVD encryption, or BluRay encryption

It's wishful thinking to ascribe magical powers to anything, even hacking over the vast labor pool of the Internet. Modern content encryption based on VMs gets broken but takes labor to break, and only works as well as it does for mass-distributed media because enough people care about it. (I'm not talking about DVD encryption and earlier. Keeping a single symmetric key secret is fundamentally broken.) Flip around the economics, so equally powerful protections are applied to data only a few people care about, and the addition of a little legal support would be enough to form an effective deterrent.

It is fundamentally broken -- for corporate mass distribution. But that's not the only thing it can be used for.
The article you link indeed shows there's surprising spending levels in some states but this doesn't quite link spending to school performance.

I'm only making this statement because it's sometimes easy to cite a correlation to support a point when there's no causal relationship. Thus, irrespective of how much a school spends per-pupil, it's critical to relate spending to educational outcomes. You could imagine a case, for example, where schools on the East Coast necessarily spend more than schools on the West Coast to maintain old buildings (I'm not saying this is the case, of course).

I'm having trouble reconciling Feynman and Adleman's advice. Adelman would rather read a novel than work on anything but the most important problems whose time has come. Feynman got his mojo back by understanding spinning plates, and famously loved to goof around with physics problems. Hamming would probably agree with Adleman here.

Perhaps they would agree that one should have some ambition and do what's important, but Feynman would have you sneak up on it from behind, while keeping the juices flowing with playfulness. I'll go with that.

Instead of making the lazy connection that he used to be a lobbyist and he must still keep those views, why don't you read some of the stuff he's written over the years, or look at some of the companies he's backed to see if you think he's still beholden to the cable companies?

Read this article from Wheeler about SOPA, written long before he was at the FCC:

http://www.mobilemusings.net/2012/02/how-sop-was-undone-by-s...

> Backed by Hollywood and others whose business model requires controlled scarcity of product, SOPA in many ways echoed the cable fight of 40 years earlier. The policy matter is not whether copyright holders should receive recompense for their products (they should), but whether legislation to protect that right is aircover to perpetuate old practices at the expense of new networks. There is no doubt there are honest-to-God Web pirates operating in China, Russia, and elsewhere who are stealing copyrighted product. These pirates should be stopped. But SOPA’s effort to accomplish this – which also just happened to strengthen the hand of content companies in other regards – applied concepts more applicable to the command and control networks of yesterday than to the open access networks of today. The result was an unparalleled protest and a political train wreck.

Does that sound like some mustache-twirling lobbyist-in-disguise?

Or his thinking about net neutrality from 2009:

> So, in a world where spectrum licensees are unwilling to part with their assignments and the spectrum agency wants to help while at the same time increasing demand, why isn’t net neutrality an opportunity for the wireless industry? Viewing the current spectrum and net neutrality issues holistically rather than in isolation just might be an opportunity for both the wireless industry and the Administration.

> President Obama campaigned on his support for net neutrality. Thus, it should come as no surprise that his FCC chairman has moved promptly on the matter, or that a Democrat-controlled commission is likely to adopt it. How it is implemented thus becomes more important than whether it exists. Rules that recognize the unique characteristics of a spectrum-based service and allow for reasonable network management would seem to be more important than the philosophical debate over whether there should be rules at all. Similarly, a rule that allows for variable pricing is an opportunity for wireless carriers to change the revenue paradigm at a time when revenue per megabyte is in a freefall.

I think some resellers were grandfathered in when it was reclassified, but not many of them were left at that point anyway. And you're right, they probably did get some sort of commission: providing the service itself was so unprofitable (even with line sharing) the DSL ISPs had to find additional revenue channels.

Server vs. Client Side Rendering (AngularJS vs. Server Side MVC)
I agree, there's no real competition for the "last mile." (If there were real competition, ISPs would be trampling over each other to deliver the best Netflix experience and bragging about it in their advertising campaigns!)

Requiring the incumbent mono/duopolistic last-mile ISPs to lease their lines may improve the situation, but I'm not as sure as Sam Altman that it would bring about real competition, because of the difficulties inherent in enforcing "fair, transparent leasing." Incumbents surely would find lots of clever ways to game any leasing scheme imposed by the FCC while technically "complying" with it.

I expect it would be better for US consumers than the status quo, though.

> Most people aren't trying to steal an image without attribution, they just want to share something they liked.

As an amateur photographer you'd be amazed how many people think nothing of taking an image and slapping it on their website, or in their print media.

People routinely use services like imgur.com to rehost images they have no permission to use, and can and will strip watermarks and be silent when asked for attribution.

> It is fundamentally broken

What is fundamentally broken is the idea of overreaching preemptive policing (DRM). I.e. the one expressed by Sony execs in the past:

https://en.wikipedia.org/wiki/Sony_rootkit#Background

> "The industry will take whatever steps it needs to protect itself and protect its revenue streams... It will not lose that revenue stream, no matter what... Sony is going to take aggressive steps to stop this. We will develop technology that transcends the individual user. We will firewall Napster at source - we will block it at your cable company. We will block it at your phone company. We will block it at your ISP. We will firewall it at your PC... These strategies are being aggressively pursued because there is simply too much at stake."

It's as broken and crooked as it gets.

> If you want DSL-style line sharing to work in the US, the line owners will need to charge the ISPs on a per-gigabyte basis. This pretty much requires the ISPs to charge on a metered basis as well. This would be an overwhelmingly bad thing for companies doing business over the Internet.

Why? It seems to me that metered internet could work just fine, if the prices are at least somewhat connected with reality (meaning cents per gigabyte at most, with a base cost not more than about $20/month). The form of metering we currently have in the US is usually punitive overage charges for data in excess of some unrealistically low monthly quota, and is applied on top of $60+/month subscription fees. That's obviously bad for internet content providers (since their whole point is to deter further usage), but I think reasonable prices are possible.
Investment dollars are definitely not coupled with profit. They haven't been for almost 100 years in the US.
Caveat: In this context, "confident" means "updates their belief less after learning the group opinion" -- i.e. continues to believe what they did before even after knowing the group disagrees.

EDIT: per klochner's correction, the following is wrong, and they did get a monetary incentive, though it's not mentioned in the linked article (only the paper), which is a pretty significant difference!

Note that they did not provide a material incentive for accurate guesses, so I'm honestly surprised that this kind of confidence correlates with correctness. It requires that this feeling of confidence is more likely to happen in people who really do know better compared to those two don't know better. (Per the writeup, if you weight each guess in the average by confidence per this metric, then you get even more accurate answers than the simple mean).
That makes sense if your services do not follow the request-response pattern (e.g. background workers). But what if they do? In Polyglot, the services very clearly follow a request/response pattern because they're handling web traffic. What sense, then, does it make to use a message queue?

Persistence? Makes no sense for web traffic. Even if the message is persisted to disk, it's useful for a few minutes at most before the user gives up and closes the tab.

Language-independence? You don't need a message queue for that. You can do that with regular HTTP.

Scaling and load balancing? Ditto.

Thanks for those links. There seem to be some good concepts in there for formulating a solution to my present personal challenge: integrating multiple disparate sources of real-time events, some transient and being delivered with low latency, and some persistent but retrieved with high latency (up to 30min!), which needs to be analyzed (and potentially replayed and reanalyzed), producing a best-effort real-time feature stream while populating (and repopulating) a reliable data warehouse. It's taking me a long time to break the problem down to the right level of components.

> As soon as a queue tries to have durable messages it is becoming a database and has all of the problems a database has to deal with. Instead you could keep data storage being solved by the data storage provider and let queues focus on passing messages.

Yes; mind you, that doesn't exclude the queue from having a persistent backing store (to reduce the instances where your application has to be involved in replay), it just means applications shouldn't use queues as the golden source of events.
I'm not sure it's the same here -- the write-up doesn't mention providing a reward based on correctness. It just says they're weighted based on how little their opinion moves when learning the group's beliefs.

EDIT: I stand corrected. As klochner points out, there was a monetary incentive to get it right, so this is like prediction markets. Not sure why the article doesn't mention this critical part. https://news.ycombinator.com/item?id=8032493

> [0] And even then - I live in Manhattan and several buildings on my block have FiOS, but mine does not (thanks to TWC's exclusive agreement with the building owner).

This is a problem with MDUs and why the big telecoms have dedicated sales teams assigned to make these kinds of deals. The more likely scenario is that Verizon was working on getting these kinds of deals set up, then they halted FiOS expansion and stopped adding new buildings before they got to yours.

I don't think contractual exclusivity is legal, but a building owner does have to set up agreements with a company like Verizon or TWC to allow them access to the building, provide a contractual basis as to who owns what wiring, etc. So if Verizon doesn't reach out to the building and set that up, FiOS isn't going to be offered.

For what type of programming? Building an embedded system is very different from building a database engine is very different from building a webapp or computer game.

I've found that dynamic languages are significantly more productive for prototyping and green-field development, at the cost of being significantly less productive for maintaining large existing software systems. And they are significantly more productive for uses where the main data types are strings, tables, and dictionaries (eg. webapps, CRUDScreen reports, command-line scripts) than uses where you need significant structured data (eg. business logic, hardware design).

Usually this means that you will need to use both - a static language forms the underlying substrate for the program, but a dynamic language lets you script and manipulate those components easily to quickly try out new features.

The issue you describe is a learning-curve one, not one specific to dynamic languages. Once you get familiar with Gradle you'll memorize most of the elements that you need on a regular basis. If instead of learning one particular popular software package, though, you had to learn the whole innards of a complex proprietary application, dynamic languages wouldn't save you any time.
