My wife and I homeschool our kids. My wife and I were also both homeschooled. We both did Saxon math through highschool. For me it was hard, boring and great. After about 9th grade I basically just opened up the textbook and worked through the thirty or so problems every day. They were repetitive lessons with a short paragraph about the concept and how to do an example problem or two. There was not much detail or explanation in the textbook. This forced me to work out the underlying concepts myself and I knew trigonometry, algebra and basic mental math better than most of my peers by the time I went to college.

My wife is more of a visual hands on learner and suffered through the same text books. In college she had a series of bad professors (like, cancelling class because the professor had a hangover bad) and this just cemented her view that she was bad at math.

All that long exposition is to say that people learn different ways and a "bad" method may result in a good outcome. Learning is a complex interplay of teacher, student, material and presentation that can be different for every person.

When I teach my kids I like to have them all in the same lesson even though they are different ages and doing different levels of work. The primary purpose of this is to just talk about math, make it normal to think and reason about it and show that it's not scary. Math concepts are often taught as a series of ever increasing obstacles to be jumped over. You jump over them until you reach a ten foot wall that you just can't summon the mental power to leap over. Then you are bad at math.

But math is more like a hike. you start out in the foothills where even your 5 year old can keep up with the rest of the family. Each footstep is a little closer to the peak. You are making progress and learning even if you only make it to the first mile marker. You get fitter and accumulate some equipment and technical skills for the mountaineering sections higher up as you go. It's challenging but fun and you have a sense of accomplishment no matter how high you are. As you get higher the vistas opened up to you show you the world in ways you could never see lower down and give you motivation to go forward towards higher peaks and better views.
Even before you commit to a factory, you can get useful information out of their production engineers, who will often tell you a thing to change to make your part manufacturable, or cheaper. But you will burn them out if you don't commit.

Harder to burn out is ProtoLabs' automated quoting/DFM site. Upload your 3D file and it'll tell you what you're doing wrong in a few hours.
The infrastructure to connect them is widespread available. It is a relatively little step to connect them with each other. That might happen faster than you'd expect.
Thank you for the correction :)
Not all US economic activity is encompassed by US listed companies; not all sales by US listed companies are in the US; the stock market can go up due to multiple expansion as well as by increased earnings.
Reasoning by analogy is not a sound way to make an argument. In fact, reasoning by analogy is always wrong to some greater or lesser degree. It is much better to directly address an argument.

Markets are created by humans when humans exchange things. The current market price express the current knowledge of all participants about the value of some traded thing. This is a decentralized process that often involves millions of different people with skin-in-the-game.

The argument against government regulation follows from this: regulation distorts the market from an equilibrium price. If this is a temporary measure then regulation is only delaying the inevitable and you should let the market reach equilibrium sooner. If it is a permanent measure, then you have a situation where the market no longer reflects the current knowledge of all participants, and at this point you start to lose the core value of a market.

By the way: markets aren't analogous to smallpox and wildfires, and regulation is not analogous to doctors and firefighters. Although this is an interesting insight into your world-view ;)

I can testify to the quality of this course. I completed both Crypto 1 and Crypto 2. Both were very well presented.
Is VEGA an actual discrete CPU architecture or something they've licensed/copied from existing chips?

Azul made their money from selling high performance JVM's they have their "VEGA" compute appliances for Java applications but I've never actually seen their ISA documentation for the hardware which would be a very interesting thing to see....
I don't think that would be the case. At first there would be indignation, but then they'd conclude that despite the pervasiveness nothing bad had come of it to them (hauled down to the met office, say), therefore it cannot actually be bad and that on balance it was probably good since it allows "them" to catch the baddies.

It's something akin to the slow boil effect.

the last 3 pos i had i "created" them myself by reaching out to people who needed something. one i responded to a job ad and ended up being hired to build something different on much better terms ( essentially as a consultant ). one i emailed 110 people in the space i wanted to get paid to work, got 10 replies 3 interview and 2 offers. one i pitched a project and got funding for equity. in all 3 cases i ensured i got people to pay me for me learning something new. so it was definitely a case of me not knowing how to do it when i approached them, yet i knew i could do it. another way to say that is i knew i could work it out. you sound like someone who can teach themselves that too. getting the work is like getting dates, it works to ask a lot of people, then care for, manage and nurture those connections. or like fishing, you got to cast a lot of times to get a couple nibbles, to land the biggun. you got this.

I think it's a good idea for inexperienced creators to design before the Kickstarter launch, but I wouldn't want to exclude the genuinely riskier ideas that require funding for R&D. Kickstarter's a perfect venue for that, assuming everyone knows the risks.
Not really. That's called losing a war. In most cases, when a war is lost, one side agrees to the terms they would probably deem unfavorable before the war had started. That's why we say they 'lost' the war.
I would list it under my "Hobbies, Interests, Activities" section if I had taken it recently. It might be a good topic of light conversation during the interview.

That's not really true. The UK led the world in aerospace until the mid-50s. If the lead had been kept rather than squandered it would have provided a huge boost to the economy.

The UK could have owned the launch business, and also owned much of the satellite business. It would also have been the first country with ICBMs, which would have changed the balance of power significantly.

There was a serious failure of imagination in Whitehall. Or possibly serious pressure from Washington.

And it happened again and again - as with the cancelled TSR2 project, and more recently with the bizarre decision to buy the F35 for the UK's new carriers, which means they'll have no planes on them for a good 5-10 years.

It's also fair to say the Nazi engineers were even further ahead. By the end of WWII German aerospace was maybe ten years in front of everyone else, with not entirely unrealistic plans for ocean-crossing jets and ICBMs.

If Germany hadn't been run by a psychopath, German technology might be where the US is today.
No, they lost a war. That's the reason someone accepts terms they don't like.

My experience, at least in Glasgow, is that often the criminals are known to the owner of the small shop the crime was committed outside, because they're often small local shops serving small local communities… and they'll just drag their feet on handing any evidence over the police, and sometimes "forget" they were meant to and just delete it as part of their ongoing fortnightly (or monthly) cycle. Showing this was deliberate and not negligence is hard.

They don't care about providing evidence to the police, because their customers might stop going if they're going to be ratted out on, they only care about protecting their own shop.

It doesn't matter if you have the best security solution because in the end, the human factor is the most vulnerable part of any computer.
Which is a good thing. It means if you get mugged, if your kid gets abducted, if you get stabbed, there may well be some garage or shop with CCTV who will have some useful evidence.

It's one of the reasons there's very little crime in the UK.

I've been lifting for a few years now and I really dislike the cargo cult mentality when it comes to heavy lifts, mainly barbell deadlift and squats. If you're not trying to become an olympic lifter, barbell squats and deadlifts will do more harm than good. There is a significant chance of injury if you perform these lifts improperly, and it's hard to know when you're doing them right. There are good alternatives to each (goblet/dumbbell split squats) which are safer.

Why not go ask Matthew Green if EKR is "corrupted"?

I feel like yours is the kind of critique you can only write after not having read my piece, as it suggests I think that Margaret Salter, an employee of the NSA, is "uncorrupted".

If you feel like suggestions that EKR might be an NSA plant are greeted with derision, the level of research and insight people bring with that very serious accusation would be why. EKR helped write Dual_EC!, they suggest. EKR's defenders think Margaret Salter is just fine! they assert.

Can you find any professional cryptographer or crypto engineer that has publicly suggested EKR is working for NSA?

That's not going to be solved by replacing flash. Or, in my opinion solved by update computer security.

Computers will get hacked. Any dominating pc OS, once found a security hole, will add thousands to the bonet.

This is really a fact. Also means, if you are targeted by some hacker, you will get DDOSed. Requiring all user to be security aware is not practical.
"for gluing together my data pipeline"

Yep. This is exactly why I gravitated toward python and scikit-learn. So much of data science is just getting the data into the right format. Grab it from this file, and this database, and this web service, then get it formatted into this table structure, and then clean it with this filter, and then plug these holes this way and those other holes that way, and now you're finally ready for a random forest baseline.

Python is a really good language for merging and parsing data from lots of different sources. For many problems, a general purpose language with very good data science library may actually be the better choice than a dedicated data science language/environment.

Please watch the first 5 mins of this interview (or all of it) with him:
https://www.youtube.com/watch?v=ehXxoUH1AlM

"Antifragile systems like volatility"

He is literally advocating the opposite of what you said. Governments are centralized and fragile (don't like volatility) hence their propensity to regulate volatility. He directly blames (large) government for the GFC - see 4:40 in the video.
Agreed. The courses seem to lack depth. And the video-only method of instruction makes it feel like an infomercial. It's a shame, because the Coursera platform has a lot of potential. Andrew Ng's machine learning course was as good as a real university course.

To be fair, the specialization I was on included a final project which could have been cool.
The major market indexes are not representative of the overall economy. They are representative of the economic winners.

First, public companies tend to be very large. They are the companies that grew at the expense of their competitors. Second, the companies in the major indexes tend to be the winner among public companies. Third, a lot of these larger companies expand overseas, sometimes in higher growth emerging economies.

Finally, IIRC, the long-term growth rate of the S&P 500 is 7% or 8% per year. That's about a 2% to 3% premium over GDP growth + inflation. That premium is the "winner" premium.

> does it cover Estrin's?

Knuth, page 488:

Another attractive method for parallel computation has been suggested by G. Estrin [Proc. Western Joint Computing Conf. 17 (1960), 33–44]; for n = 7, Estrin’s method is:

Processor 1: Processor 2: Processor 3:
a1 = u7*x + u6 b1 = u5*x + u4 c1 = u3*x + u2
a2 = a1*x^2 + b1 c2 = c1*x^2 + d1
a3 = a2*x^4 + c2

Processor 4: Processor 5:
d1 = u1*x + u0 x^2
x^4

Here a3 = u(x). However, an interesting analysis by W. S. Dorn [IBM J. Res. and Devel. 6 (1962) 239–245] shows that these methods might not actually be an improvement over the second-order rule, if each arithmetic unit must access a memory that communicates with only one processor at a time.

* * *

Personally this seems like a lot of implementation trouble and communication overhead, and I suspect it will lose out badly to a GPU cranking out evaluations at separate points.
The project is the Triggertrap Ada. https://www.kickstarter.com/projects/triggertrap/triggertrap...

The product could've easily been made on their budget. Their problem was outsourcing much of the development work, so they paid consultants too much money to make something that was overdesigned and way too expensive to make. When you're starting in hardware, you need to immerse yourself in the whole chain to be able to make good decisions. Shame, I liked the guys.

More practical discussion of their missteps:

SoCs with 8GB onboard is a pretty niche chip, but other than that it's all out there. The Raspberry Pi/2 is actually a pretty poor offering - you can do better, even at the same price, The Pi Foundation just does a better job of marketing.

Specific models are the ODroid XU4, the CubieBoard or Cubietruck, the Banana Pi, etc.

They're not cheap, but the Jetson TK1 is an extremely powerful offering for this category based on the Tegra K1 SoC. You get SATA, USB 3.0, mPCIE, 1GigE, GPU with 192 Kepler cores, etc. If you need some grunt you can even do CUDA compute. Again, I'm still waiting for my Tegra-X1 based Jetson, NVIDIA :<
I think it's just that - the type system gives you so much, most hackers see a text editor with minimal type checking as good enough. Also IDEs tend to be commercial and I don't think any of the big companies see Haskellers as a good chunk of change. There's also quite a stigma many developers carry around regarding Haskell, though I don't understand that.

> Zwicky's work was largely forgotten until the 1970s, when astronomer Vera Rubin discovered that nearby galaxies were not spinning in the right way.

What Vera observed was that the stars in distant galaxies were all spinning "together". One would expect some stars in the galaxy to spin at a faster speed than others at varying distances from the center. What she observed is akin to a single "galaxy" bitmap rotating all at once, where the relative positions of the stars in the galaxy "image" being in lockstep with each other.

Dark matter. Hehe.

Surveillance is worse. In 1984 there was one camera and one microphone per room. Now we carry multiple cameras and microphones and tracking devices everywhere we go. In 1984 the party had to break into an apartment to read a person's journal. Now our most private thoughts are stored in text messages, private Facebook posts, and Evernote, within easy and undetectable reach of governments. Behavioral analysis can tell surveillance operators things about us that we don't even know about ourselves. Every person we talk to on the phone, every page we like, every link we share on our blogs can be wired together into a graph of our identity, ideas, and social networks (see software like Palantir).

Not to mention that the phones aren't always listening, always recording, and always reporting my location any way. I they were, my battery would last 3 hours tops.
and these large "private sector" companies, are they actually private sector or are they really just a front to make them look like they're private sector companies, when in reality are owned wholly or in part by entities specifically for the purpose of dragnet surveillance by intelligence services whilst selling their services "as a convenience" to other companies?

Given how we've been sold devices for convenience that it turns out are being used against us for many years, I would say that it's just as likely that this is happening on all levels.

With what we're gradually finding out since the Snowden Revelations, one can naturally assume: Any mass market product which appears to make life easier for a large enough percentage of the market whilst potentially compromising privacy/security is almost certain to be used in such a manner - that goes for consumer products as well as commercial.
I have seen folks who have done this to get some sleep in a warm area, the '22' bus route on El Camino in the Bay Area is sometimes called the 'hotel 22' by folks who buy a ticket and ride from one end of the run to the other and sleep on the bus the whole way.
The deadlift will get you the most results for the amount of time you put in. It directly strengthens all the muscles involved in keeping you upright and in a normal anatomical position. A barbell and plates will put you back about $250-$300. Then, if you spend 20 minutes every Monday, Wednesday, & Friday deadlifting and just increase the weight on the bar by 5-10 pounds each workout, you'll be a totally different (better, stronger) person in about 2 months.
Kelly Starret has a great quote about this: "your best position is your next position".

Which is really another way of staying that you should be moving and changing positions frequently. Sitting to standing, on a stool, one foot up, then the other, etc.

You can really run in to problems when you are sitting in the same horrible posture for hours on end. One side benefit of a standing desk is that it makes it a lot harder to stay in one position for hours because you can't slump back against a char. So you actively have to find ways to support your own weight, or at least you realize you are slumping forward in an awkward way onto the standing desk and you change position.
Hence why learning proper form is key.

I do understand where you're coming from though. We often times see guys at the gym quarter squatting or pulling with a rounded back which is indeed doing more harm than good.
I would like to see how a system like this would fare against something like the Einstein puzzle. And how it would fare against a human when it comes to real-world tasks and descriptions.
