I've worked with all these guys, and the most plausible reason I observed boiled down to anti-counterfeiting: in their view, data sheets are a map to creating register- and pin-compatible clone parts.

While the knockoff market is very real, it always seemed far-fetched that NDAing data sheets would be that much of a protection. You would think a sophisticated shop has enough relationships to get the sheets via a close contact, friendly supplier, etc..

I'm not sure that there's much value in this article.

1) It doesn't really compare benchmarks on OSX vs Linux - you're dealing with different drivers, kernels and filesystems.

2) Then there's the matter of EXT3 - there is little to no value in benchmarking such an old filesystem with modern hardware, not to mention that EXT3 lacks native trim support thus major impacting performance over time (This is assuming the host OS is also using EXT3 and thus not passing through the discard IOCTL to the block device).

3) There's no mention of what Kernel version was being run, modern kernels (3.6+) are significantly more efficient with both disk and network I/O.

4) How much memory is being provided to the host and guest VMs and how much of the 'benchmarks' are being cached? What kind of disk / filesystem caching are they using? What is the IO scheduler for both the guest and the host machines?

5) What 'benchmarks' were actually run? I'd bet that it involves using dd which is by no means a benchmark - nor can it be trusted (especially without what commands were even being run) - if you're going to benchmark disks use fio or bonnie++ (although I think fio is more useful)

Here's a good article on how to perform a few kinds of useful benchmarks: https://www.binarylane.com.au/support/articles/1000055889-ho...

Beyond that, I'd also look at using PGBench to get an idea of the IOP/s in real world scenarios: http://www.westnet.com/~gsmith/content/postgresql/pgbench-sc...

That's a bastardisation of loyalty though. Yes, people volunteer, because they are expected to.

What about speaking up about a situation that is going to get people killed? What about the people who didn't volunteer, where they fine with the whole thing as long as they weren't affected? Is the commander visiting his guys after years and year when they are dealing with PTSD?

I used to joke that I had more bitcoins than I could spend in my lifetime. Not because I had a lot, but because there was fuck all to spend them on.

I just paid for my lunch in Bitcoin. Not as some evangelical, cryptanarchistic statement, but because I have bitcoins and I needed lunch. The mechanism for paying is on a par with credit cards, if not slightly above. I've watched the monetary value of my bitcoins plunge in the last year, but I've seen their practical value to me increase massively. A year ago I could buy precisely zero lunches for 1 BTC, now I'd get at least 50.

How about not reelecting a president to a second term when he started the war in the first term?

The reality is that had the opinion polls indicated that he would be resoundingly removed from office, he would never have gone in. He needed permission from a group of people who value re-election above almost all else. As he himself did. Even in the middle of a 4 year term the people have the power - the problem is that they approved.

To imply that the war was against the conscience of the majority of (voting) Americans is a falsehood. They were consulted, and their response sealed the national decision. As such the soldiers were respecting their oaths and their country.
Bitcoin gives you two currency exchange transactions to do where previously there was only one. I can't really see it taking off except for transactions that are banned from one of the other payment systems, and given that transactions are entirely public with persistent pseudonyms, that's not great either.

Bitcoin's transaction cost and risk is necessarily greater than any centralised solution, so as soon as it establishes a useful market it can be undercut. (Don't quote the minimum transaction fee in response to this, quote the miner electricity cost per transaction, the exchange bid/offer spread, and the escrow fees if relevant).

It's entirely trivial for value to be destroyed: this is what happened in the leveraged property downturn as recently as 2008.

"Just fix your current account deficit" is about as useful a piece of advice for countries as "just create jobs", ie not very.
Q-learning is not a lookup table from states to actions. It's a learned mapping (using any method you want, such as neural networks) from agent history (i.e. the agent is allowed to consider the past) & action pairs, to estimates of future reward, learned through temporal differences between the prediction at time step t, and the sum of new prediction plus immediate reward at time step t+1.

In this way, information can flow back in time as the agent learns that some observation is predictive of reward, and then learns some observation is predictive of that observation, and so on until it connects the reward with some action K time steps ago. So long-term planning is definitely possible.

This does require that some relevant information be available at each intermediate time step to connect the actions with the ultimate reward. The nice thing about these Atari games is you can usually judge value just by what's immediately on the screen, and in this paper they only use the last three frames' worth of state. In a game requiring a memory for past sensory information (e.g. where information appears on the screen then disappears), this might not do so well, but that's more a matter of working memory than long-term planning, and a different Q-learning system could contain a working memory (e.g. if it was RNN-based).

It is an error to mention Microsoft in the context of Venture Capital backed firms except as a point of comparison. Microsoft was not VC funded. That's one reason why its IPO made the world's richest person and created 10,000+ millionaires.

I had to chime in here and congratulate you on your fine explanation of the concept Plato deemed the Noble Lie. I don't want to assume you know of its but I'll go ahead and do so anyway, since you seem the type.

For others, it's truly fascinating : https://en.wikipedia.org/wiki/Noble_lie

Humans so readily eat them for breakfast, lunch, dinner and in our dreams.

Not to say I am such a grand detective at the age of 23, but I feel as if the building software has taught me (and will continue to teach me,) many valuable logical lessons, which help me to methodically deconstruct things beyond programming (stories, my beliefs, other people's beliefs.) This would make sense since usual we build software by translating those things (stories and beliefs) into the fractal complexity necessary to achieve a real solution.

I can't think of any better substitution than teaching logic through programming since I happen to agree with one of the parents in that pure logic in philosophy is slightly harder to pin down concretely for younger minds. They are also less apt to pick up on and find existential value in philosophy.

In other words, I'm completely for programming literacy in middle, and high school. Especially for it's ineffectiveness with logic, but also to since they are just beginning to realize the complex programs in their very own mind (built by themselves... or others.)
I'd want them (and everyone) to know how to deconstruct and find roots, reasons, and rationale.
I think computer science has more to do with engineering than science. Like learning Latin, learning computer science has some side benefits in term of learning rigor, logic, etc. But that should not be a primary motivation.
It's relative, but yes. Spend some time with people who served under the UN and you'll hear all about it.
Interesting. These sorts of headlines bug me, in that they reject computation itself as a novel medium of expression or externalizations of mental models.

I think modeling is very important, but Chris seems confused on how to reason about education. The core message, that we want children with higher levels of cognition than mere factual knowledge, is good, but rather obvious. His core conclusion that we don't want a generation of people caring about code has nothing to do with this, and is very misguided. This basically rejects computation as an expressive medium outright in favor of the usual writing and mathematics ("writers and accountants"), rather than recognizing computation's new role in society and new jobs that leverage it (business analyst with his Excel macros, quantitative analyst or data scientist with his combination of statistics and scripting, software engineers, test engineers, architects).

It's almost like Chris took
Bloom's taxonomy (not actually a taxonomy, but useful) http://en.m.wikipedia.org/wiki/Bloom's_taxonomy of cognition and decided that the foundational element - knowledge - basic reading, writing, coding, math, and facts - is irrelevant. This is not irrelevant, it is the foundation on which we build comprehension, then application, then analysis, synthesis, and evaluation. This he calls specification, exploration, validation, and debugging. Good luck teaching someone how to apply a model, let along synthesize one, when they can't do the basics of expression. This gets into the philosophy of education, and perhaps this article is just a reflection of the current trend away from rote learning, but this is an active debate, not settled science. This trend may lead to some bizarre outcomes: I see 15 year olds that can't read a wall clock or understand basic techniques around fractions, though they can describe and do basic reasoning about them.

Secondly, I believe coding itself is a fundamentally new area of knowledge, and every debate about "coding is the new literacy" really comes down to whether you believe this or reject it. Rather than convince you, all I can do is quote from the preface of SICP http://mitpress.mit.edu/sicp/front/node3.html, one of the great examples of computing pedagogy we have:

'Underlying our approach to this subject is our conviction that "computer science" is not a science and that its significance has little to do with computers. The computer revolution is a revolution in the way we think and in the way we express what we think. The essence of this change is the emergence of what might best be called procedural epistemology ­ the study of the structure of knowledge from an imperative point of view, as opposed to the more declarative point of view taken by classical mathematical subjects. Mathematics provides a framework for dealing precisely with notions of "what is." Computation provides a framework for dealing precisely with notions of "how to."'

Yes, modeling is important - it's a a higher level of cognitive reasoning. We still should teach kids to code.
Or the algorithm that found your face will just learn to find these.
Tesserace 3D Path Tracing Test (WebGL)
Can Big Data Measure Livability in Cities?
Why would this situation be disanalogous to when we prove anything else in mathematics? There's always a chance that anything we believe (well, almost anything) could be wrong.

If you think that disqualifies any man-made proof from being worthy of the name "proof"... perhaps you would be interested in studying philosophy of mathematics? :)
What It’s Like to Need Hardly Any Sleep
>Why not teach with philosophy?

That sounds great but almost nobody teaches philosophy to children right now, and that does not seem likely to change in the near future. Our utilitarian ideas about education (you know, workforce training) make it easier to support teaching of subjects that are more directly relate-able to work.
> As a value exchange mechanism... Certainly.

I'm working on a side project at the moment, and one of the fantastic parts of dealing with crypto coins is that going from nothing to being able to take payments is down to installing bitcoind (or the equivalent for other coins) and issuing jsonrpc commands to it.

Especially in countries where signing up to take payments by cards is cumbersome/slow, that's fantastic.
On a day-to-day basis, bitcoin takes ages to confirm that payment has been received, supports somewhere around 3 [three] transactions per second, and shifts risk from sellers to buyers (e.g. compare refund possibilities with credit cards).

There are various hacks that are being proposed to increase the number of transactions per second, and reduce confirmation time. Ultimately, they're just that, though: hacks on a proof-of-concept.

What I'm really interested in is whether it's possible to have a cryptocurrency that doesn't rely on e.g. blockchain technology.

How you'd fix the issue of double-spending ("I can just copy-and-paste my money - yippee!") without a blockchain or equivalent is beyond me.

I'm just really intrigued by the idea of being able to cryptographically sign over a digital $5-equivalent -note to someone else, instantaneously, and without relying on a third party saying "Hmm, yep, that note looks legit to me".

Sadly, a lot of bitcoin's popularity seems to come from people who sincerely hope and believe that it's their lottery ticket to millions in the future. Whilst these people are vocal, it's probably a good idea to be aware of and filter out their voices.
I'm not an expert in this subject but IMHO:

1-Bitcoin is just an huge ponzi scheme.

The early birds to got into the system are the ones that will have HUGE profits. So I want to create my own currency and be able to get an advantage also.

2-Bitcoin is unfair.

Besides everything governments taking care of currency seems the most fair and democratic way of dealing with it. With Bitcoin technical people have advantage over non-technical people. It remembers me Nietzsche when he writes something like:

"There are only 3 types of people: the rich that wants to keep being rich; the poor that wants to be rich; the intelectual, that using his ideals (advantages) wants to be rich."

I had to look up what the "Wason-test" is[1] -- and I'm not convinced it proves people do not have a good grasp of basic logic. I think it shows that people don't see logic as a useful tool in determining the classification of a grand total of four real-world objects.

I think people are just better at optimizing their brain power than that, with just four cards, why not look on both sides of all of them? You examine twice as many cards, but you'll probably complete the task quicker than if you think carefully about the wording of the question.

Bitcoin is here to stay for at least this one reason: gambling.

I have bought and sold more bitcoin since I started sportsbooking and playing poker with it than I ever had before.

With services like circle and bitcoin-friendly gambling sites, I am able to instantly deposit and withdraw to my gaming site, and then within 2-3 days have my winnings back into my bank account in my native currency.

It is really a better system than I have experienced gambling online with fiat previously.
I would say that their competitors have failed to provide a better alternative.

It's logical sentiments that have faded to the unconscious. If the society you are within has the same elements in their unconsciousness, information bandwidth to convey a message is reduced for all parties, with An unknown amount of subtle complexities (within messages) still successfully conveyed.
