I'm interested in this too. What I've been wanting is a single chip solution.

I've designed various systems based on arm7 chips, but my naive lisp implementations barely fit any usable system into the onboard RAM (~90k).

I've been waiting for atmel or someone to put something like 1MB or so on chip, but the market for such devices isn't there.

FORTH seems better able to fit and has a little better fundamental underpinnings than BASIC.

I agree with what you are saying, but I was talking specifically about digital distribution. Closed platforms like Kindle definitely cause some lockdown, but Kindles are relatively cheap and replaced as often as yearly. If Amazon did start gouging on prices, a lot of people would switch to Kobo or Nook.

With digital distribution, you can guarantee that everything you're selling is always available for free (with the risk of legal fines) from other channels. Companies like Spotify, Netflix, and Amazon's digital distribution are aware that they are competing with free and tailor their services to be worth the cost. Physical goods that require factories and distribution centers will be a barrier to entry for a long time, at least until commodity 3d printers can compete with large-scale factories, which will take some time.

How David Braben's 1984 space game Elite inspired the Rasberry Pi
As someone inside the higher education machine and who is married to a long-time teacher, that's false; there is no conspiracy to keep kids dumb in schools.

The problem is that we're tasked with coming up with a universal system of education for an unbelievably varied skill set presented by students. So, we shoot for the middle (or just slightly below the middle when parents complain that it's too hard). Combine that with apathy and burn-out among the aging workforce in education, and you get the full picture.

There's no conspiracy, just an averaging out of student abilities and bitter, resigned teachers who are tired of being told how to do their jobs by politicians and loud-mouths in the media.

Whether or not critical thinking skills are being fostered in our current system in all classrooms, that's another question. But, there is no conspiracy.

As a side note; working in programming and engineering doesn't magically imbue a person with more or better critical thinking skills than English literature or art history.

Hypothetical question: is it possible that they did not copy it? The author here indicates that the original maze was generated by software, maybe Kraft stumbled upon the same algorithm, or a close variation of it (considering the minor differences between the two)?

Obviously, this is very out-of-left-field and I don't believe it either, but it's not impossible that Kraft didn't plagiarise anything.

One funny social dynamic to watch with the pi is you give people a little computer with specs that would be pretty good five or so years ago and you get some responses like:

"Humanity didn't use computers five years ago at all, for any purpose, being capable of doing anything that was done five years ago is inherently totally useless today and any thought of it should be abolished because I say so la la la I'm not listening to your real world examples la la la and that's somehow your problem not mine la la la". If you ram it past their self censorship to prove there exists a real world application for a five year old computer they get really angry. Its kind of funny to watch.

Maybe its astroturfing from people selling more powerful computers.
I think once you gain a more than superficial understanding, you'll be happy with Rust. :)

> the shared reads of an immutable value are embarrassingly parallelizable,

This is absolutely true, and Rust lets you do that. You just have to dot your is and cross your ts: https://gist.github.com/steveklabnik/8de9b9b0ae2e45383d85 Rc adds reference counting, to ensure that this reference will be okay for the duration of all of the threads. If you just used a regular old boxed value, one of the threads could invalidate the reference.

That's just one example. As you say, there'll be libraries eventually: people have been focused on the language itself, and given how easy Cargo makes it (will make it) to share libraries, I wouldn't be surprised to see an awesome persistent/immutable data structures library appear.
The numbers are referring to the wrong voltages entirely. It takes in 5V and down-converts that to 3.3V, 2.5V and 1.8V.

It is only "your god damned job" because you can't let go of the fact you're programming on some machine. You should be trying to abstract from that so your programs are more portable and less implementation-dependent. Will you also be obsessing about the internals of the next computing paradigm? I'd rather solve real-world problems in a general, machine-independent way, instead of focusing on the moving parts of a machine that is simply incidental to my job.
They may not have to license it, but for a reasonable price I'd rather use a well-implemented library that excels at what I need it to do and goes beyond, than spend time hacking up something equivalent but inferior (hey, I've got other stuff to do too).
Locks are not trivially pickable. It only looks that way if you watch a skilled person do it. It's much harder than many impressive juggling tricks, for example. Smashing in a window, now that's trivial.

Neither matters though, because a big purpose of locks is to show that you took reasonable precautions in order for your insurance to be valid. (YMMV, IANAL, etc. but that's the case here.)
Ignoring the obvious hyperbole of your first sentence, sure politics essentially sets the curriculum (for better or for worse). That doesn't excuse the political system also getting in the way of teaching it.

Mercifully in Australia we don't have standardized testing every year (yet), but enough importance is tied to the tests that do take place that a disproportionate amount of time is spent preparing kids for the style of tests administered, regardless of any gaming of the system, reducing the time spent on the rest of the curriculum.

I know we've argued education before and so I'm not expecting a hallelujah moment, but I figured it was a point that should also be made.
The low pulse of athletes is adaptively suppressed metabolism. It is not a good thing. The body deliberately reduces resting energy expenditure as a conservation measure because it anticipates the extreme energy demands of training.

Sprinters and strength athletes do no get a suppressed heart rate. It's only endurance athletes and others who train high volume.

This is well understood by a lot of trainers. Low pulse and low body temperature in the morning is an easy way to measure over-training.

People need to get it through their heads that highly trained "fit" athletes are not very healthy, as a general rule. They tend to develop problems relatively young. Marathon running is worst of all, each marathon run showing a statistical reduction in life span.
It could be useful to learn an "almost" functional version of Lisp, like Scheme/Racket or Clujure. (You can also try to write "almost" functional code in Common Lisp, but the usual idioms are more imperative.)

The idea is that you write "almost" all the code in small functional functions without side effects, but you can use side effect when the functional solution is very difficult.

Most of them are not typed (there is a Typed Racket version, but the type system is not similar to the Haskell type system).

We researched dark coating for astronomical telescope.

0.00035 albedo is pretty impressive. It does not reflect any light, nothing human eye could focus on, so it is impossible to judge distance and details. It is practically invisible and alien. So wall out of this material would appear as 'dark hole' and we would practically walk into it.

We did also experiment by covering room walls with dark cloth, so it would not reflect any light. It was strangely claustrophobic, you could only see light bulb filament and nothing else. Something like this picture:

I think it depends how absent light can be. In most blacks, its not entirely absent. What they are saying is that this black is the blackest so far, in that it creates the condition of near total absence of light - not easy, on this planet.

Interesting that its conductive qualities are so special .. I guess this means its the hotblack of all blacks. A kind of blackest of black. Or to put it lightly, black on black.

At any rate, this blog post provides the quote in question, from page 229 of "Omnivore's Dilemma" though it turns out it's the USDA, not the FDA that is mentioned.

http://www.businessweek.com/smallbiz/running_small_business/...

Here's the quote:
"The problem with current food-safety regulations, in [small farmer Joel Salatin’s view], is that they are one-size-fits-all rules designed to regulate giant slaughterhouses that are mindlessly applied to small farmers in such a way that “before I can sell my neighbor a T-bone steak I’ve got to wrap it up in a million dollars’ worth of quintuple-permitted processing plant.” For example, federal rules stipulate that every processing facility have a bathroom for the exclusive use of the USDA inspector. Such regulations favor the biggest industrial meatpackers, who can spread the costs of compliance over the millions of animals they process every year, at the expense of artisanal enterprises like Polyface [Salatin’s farm]."

I was born and raised in Atlanta, Marietta specifically. It is a wealthy area with some of the best public schools in Georgia. I went to Dickerson Middle School. The vast majority of my peers had 2 parent homes. Both parents worked and could afford a babysitter/nanny, or one parent's income was enough for the other to stay home. The area is incredibly safe. I rode my bike to school.

At Parks, as this article says, the majority of students have a single parent household, with drug abuse problems, and extreme poverty. 2 of Parks middle school students were raped in a single school year.

Comparing Dickerson's test scores to Parks's test scores is insane. Should Parks, and schools like it, be held to certain standards? Yes. Absolutely. But excellence in education is affected by far more factors than the quality of the school and its teachers. The article discusses how Lewis, a teacher, was operating almost as a social worker for many of these kids (doing laundry, driving them home at night, etc).

The solution isn't "throw more money at the school" or "hold them to a standard test metric." Its more complicated than you think. Education, crime, employment, these things are linked. We can't address these in isolation.

I defined gaming as "aspects which influence the test results other than proficiency in the subject matter."

I did not define it as "education in the course material". Please don't make that assumption.

It's impossible to evaluate your example without defining the pedagogical goal. Your example test question cannot distinguish between proficiency in multiplying two three-digit numbers, and proficiency in selecting from one of four possible answers, where two are obviously incorrect.

That said, this question is biased in favor of students who have been taught estimation techniques, in this case, round, compute 20 * 10, and look for the closest answer. They will be able to answer more of these types of questions than students who can actually multiply the numbers, but haven't learned the approximation methods.

Had the answers been "1) 257.24, 2) 256.24, 3) 247.34, 4) 248.34" then the other class of students would fare better. Then again, those who learned casting-out-nines would be able to reject two of these quickly.

It's clear that sometimes ballpark answers are better than exact ones. In bookkeeping, it's clear that exact answers are better. It's possible to teach students both ... by taking time away from other skills which are also part of mathematical proficiency. A standardized testing system encourages monoculture teaching, so that all students are primarily taught the method most likely to be on the test, on the assumption that the test defines proficiency.

It appears that you have defined "proficiency in the subject matter" as "ability to pass a standardized test." If so, then by definition it's impossible to game the system, making this discussion pointless. Is that your definition of proficiency?

As a Horizon user, it bugged me that so much of the image was cropped to ensure stability (portrait width in landscape orientation - grrr). The rotate-to-zoom effect isn't perfect, but at least it gives the option to use more pixels when available (and I'll take zoom over wobble). Otherwise you're using an HD camera to take stable SD video.

You do have the option of turning off rotate-to-zoom and stick with the prior low-res stabilized image.
More economical? Almost certainly. That day is already be here for many with services like ZipCar and existing taxi and taxi-esque services.

I don't see the current technology making car sharing/ride purchasing more convenient than owning a car anytime soon. It's hard to beat the zero waiting for a given trip, and even if you include the implied waiting time at the end of your prior trip (finding a parking place, etc), people get more annoyed waiting to begin doing something than they do if doing something takes a little longer.

By necessity, any test can realistically test only a subset of a student's knowledge. If the patterns that the tested subset follows are easily predictable or have a simpler structure than the actual knowledge, you can get better performance by teaching those patterns than by teaching the actual skills.

Multiple choice tests are particularly egregious examples, as for them you only have to be able to verify an answer instead of having to derive the answer.

Standardized tests are rife with multiple choice tests and questions that follow predictable patterns.
Did that actually happen? I know someone who worked at a shortwave (a.k.a. microwave) radio station when that almost happened. They had to shut down the transmitters occasionally to paint the radio towers, but someone had the bright idea that they could just power down long enough for the painters to climb on. Then, when they weren't grounded, they could power it back up during the painting. They actually did a test run with chickens before it dawned on anyone that they would be cooking anything up there!
