> In my snowboarding groups, there were usually about five students, no more than ten. We would spend a full day together, and I had time to spend quite a lot of time with each student individually. In my math "exercise" classes, there were up to 25 students. I would see them 3 hours a week (they had other teachers as well).

For the same hours of instruction block classes leads to poorer long term recall. Five students is the absolute upper limit of what can be considered tutoring. By the time you have ten students you’re into class teaching where the difference in learning between small and large class sizes exist but are not large enough to justify the greater expense in terms of learning.

> Snowboarding students have usually quite similar level of abilities. Of course, some learn faster than others but nobody improves 10 times faster than someone else (which happens in maths). If a student is better, she/he can move to another group the following week (something impossible in my math class).

We’ve known the solution to this problem since at minimum 1968 when Mastery based learning was named, and the first research on the topic dates from the 1920s. Don’t let students proceed to topic 2 until they’ve gotten 80 or 90% on a test on topic 1.

> As a math teacher, I'm also the one who evaluates them, and who stands between them and their degree. As a snowboarding coach, I'm the one who helps them achieving their goal. Different dynamic.

Again, this is a solved problem. AP tests exist. Math contests and the Putnam exist. The Royal Statistical Society used to set exams covering the first year, first two years and entire curriculum of a U.K. statistics degree, which latter was sufficient to get you onto a Master’s programme. They stopped due to lack of demand. Separating teaching and certification exams is not that hard.

Apart from differences in native ability Mastery learning and separating certification and teaching functions solves these problems. For whatever reason they’re not widely applied. In a developing nation context with very large classes the UK’s DfID has found that the most cost efficient method of improving education is teaching children by skill level, not age, which looks awfully like mastery based learning. There may be individual university departments that do this. I’m not aware of any. The only institution I know of that does Mastery based learning is Lambda School. It’s hard and requires complete institutional alignment. The closest universities come to it are weed out classes and prerequisites. An economics professor of my acquaintance started requiring calculus for his game theory classes, not because he uses calculus, but because it assured him that all students will be solid in algebra.

Looking at what institutions do instead of what they say their aims are they look much more like ranking institutions than teaching ones. Ebbinghaus’ forgetting curve research dates from 1885 and is an educational curiosity rather than a core part of instructional design. Most students forget most of what they’ve learned. If we wanted to teach instead of rank education would look enormously different from what we see in practice.
I want to believe me neither but lately I've researched some personal medical issues and the amount of well written absolutely not-scientific (while citing lot's of studies) blog posts / sites that sell you something and make you believe you have an non-existing disease that's easy to self diagnose (https://en.wikipedia.org/wiki/Adrenal_fatigue) is pretty high for any medical topic.

There's a description of the particular fault injection used for the Gameboy Color here: https://www.its.caltech.edu/~costis/sgb_hack/

Fault injection is a method to cause microprocessors to execute instructions "incorrectly" by manipulating external factors (clock frequency, input power, etc). Getting the CPU to fail to write to a memory address, or flipping the truth of a comparison instruction, and other "glitches" can influence execution of security-sensitive code and ultimately undermine security mechanisms.

The original Gameboy ROM was dumped by physically de-capping the chip and reading out the bits: https://dot-matrix-game.blogspot.com/2014/01/boot-roms.html
ADHD sucks. I mean, it ain't cancer, but it sucks. I was never officially diagnosed, but when my son was at 7 is when I realized what ADHD really is, and that I'm an ADHD guy. Some how I made it through 40+ years with it and never knew it. I struggled though college, took me 9 years to get my BA. Somehow got a masters. Somehow managed to get a series of better jobs after my degrees. And I've somehow succeeded in life (my definition of succeeded) with ADHD and without any help or anything. I struggle with it every day still. ADHD sucks, I have no idea how I got to where I am, but I know I'm lucky. It's also made me a better parent to my ADHD kid, I know what he's going through, it's taught me patience and kindness that I never had growing up. If you don't know much about ADHD , it's not what you think it is.
I agree it's not very prominent, but there are brief profiles of individual artists on the page for a specific product.

I don't think there's any way to know for certain post-mortem; but at least in all the descriptions I've read of strokes, causing a sudden fall within a split-second seems unusually abrupt, while falling is an extremely common and ordinary event in the elderly and having a stroke after hitting your head so hard as to break your nose doesn't seem like too surprising a thing.

>>> I would hope he was at least comfortable on his bedroll.

Most humans on this planet don't sleep in the big fluffy beds that are the norm in the USA. Many, myself included, find them too hot and generally too soft to be comfortable. An inch or two of dense foam over a hard floor is fine for me.
Your other responses are excellent.

But I want to say this is another TANSTAAFL. You worked, had skills, and otherwise "worked" for your loan.

If loans are "free" like student loans, the costs can end up being even higher.

What will happen is that once there's enough examples like your biologist friend, the government will forgive them with a TARP like exercise. That might be OK if the underlying system changed and we stopped loaning out money to people unlikely to hand it back.

And the money ends up bloating the academic bureaucracy anyway. Not enough ends up improving or providing education.
Or we could just use that valuable fuel and put it into nuclear reactors to make energy and other useful stuff. But that seem to be a totally crazy idea.
Reminds me of one Computer Science professor I had whose degree was in Philosophy - of course he predated computer science degrees. He is part of the older branch of "self-taught" as opposed to degree trained in programming - it is now rarer for someone new to get into the field at a higher level without formal training.
With serverless, you can have your functions running on machines all over the world, at the network edge closest to your end user.

You can do that with containers and VMs too. Potentially with fewer worries about cold start latency (at least with Lambda).
Hmm; would I rather Google have access to my data, or the Chinese Government?
We were talking about lock in. And my argument was that making it harder to get your pictures onto another device without using another apple service is a form of lock in. It is a computer you should be able to connect it via USB and drag files over.
I guess the most prominent counterexample is Germany, which has basically free tuition. They also have different kinds of high schools preparing people for universities or trades, not everyone needs to go to university.
That does not sound unreasonable.
I slept on the floor like this too. I read about why we invented beds and it was to lift ourselves up away from insects on the ground.

Then we invented floors. Then carpet and only poor people had wood floors. Now rich people have wood floors and carpet is cheaper so "less high class."

Point is: A lot of our style/design choices are made with the explicit intention of costing more money as a way to separate the financial classes.

Thus, it's not just to protect their right to live normally, but to protect their status in society.
K12 Mathematics education is mostly a giant waste of time, teaching children things they’re just barely capable of learning now that they can pick up in a fraction of the time a few years later. Sudbury and other democratic schools can teach the entire primary school math curriculum to 12 year olds in around 40 hours. You can teach a nine year old to read to grade level in about the same amount of time. Primary school education works wonders at teaching children to sit still, do what they’re told and doing complex, boring tasks on command but as education it leaves a huge amount to be desired.
"Carbon-free" is a standard industry lie. Uranium mining and processing produces massive amounts of carbon and pollutes the earth with tailings.

The nuclear industry externalizes their costs so that they don't ever hit the balance sheet.

What is "insurance for global warming?" That isn't even a thing. But government insurance for nuclear plants is very much a thing.
This sounds amazing because it shifts blame for poor performance from lack of simplistic analogy to easier examples to a lack of preparation, but I don't think what you're saying is true. Some people are born with a higher ability for some things, I genuinely doubt that people in math majors not as quick on the uptake can just be brushed aside because they didn't "prepare" as well as they should have.
Von Neumann had the full-time 1:1 attention of a (presumably brilliant) nanny and significant 1:1 time from several additional expert private tutors starting from an early age, as well as a ton of parental support. That is way more useful than sitting in any classroom. Then he was the kind of kid who liked to walk around town doing arithmetic calculations in his head, and was passionately curious about everything and spent tons of time reading throughout his childhood. By the time he got to school he was several years more prepared than most of the other students.

The dude was obviously very clever, but it’s not like you can learn to speak several languages and understand advanced mathematics from scratch just by staring at the wall with no input or feedback.

My 2-year-old has a bigger vocabulary and better grammar than any kids his age at the local playground. That’s because we read challenging books together 2+ hours per day, not because he is some kind of superhuman genius. He also runs faster and with more stamina – because he gets a ton more practice than most running and playing outside. On the other hand, he doesn’t fluently speak 4 languages like the kids whose parents speak 4 languages to them daily, he isn’t so good yet at climbing or throwing or drawing since he isn’t very excited about those skills/activities yet and doesn’t practice them regularly. It’s not a priority for me, but I would not be at all surprised if he ends up learning basic calculus before age 10.
Here's the authoritative summary of the capabilities of transmutation and partitioning [1].

Thorium reactors do indeed produce fewer transuranics, since Thorium-232 is 6 AMUs lower down the chain than Uranium-238. Used nuclear fuel is generally 95% U-238, 1% Pu and minor actinides, and 4% fission products. If you do chemical separation to partition the transuranics you can then try to burn them in a variety of reactors. In slow-neutron reactors using Thorium or Uranium fuel, they'll burn ok if they're well partitioned. In fast-neutron reactors, you can burn them with out as aggressive of partitioning. So it's probably easier and cheaper to reprocess UNF for fast reactors. They're far less sensitive to neutron-poisons and fertile species (e.g. fission products and U-238).

Any breeder reactor will make 2 orders of magnitude less TOTAL waste than a non-breeder. Thorium can breed with slow neutrons (which requires continuous removal of the neutron poisons via online chemistry, usually requiring fluid fuel). Uranium can breed with fast neutrons in solid fuel or in fluid fuel. Note I say total waste, not high level waste. High-level waste is proportional only to the burnup (fraction of the fuel you put in that gets fissioned) and doesn't include any process waste from before that (e.g. enrichment or reprocessing waste like U-238).

In a fast neutron uranium-fueled reactor, you can transmute the hell out of all actinides, leading to waste that decays to low levels in a few hundred years. See the link below.

Thorium's only true physical advantage is that it alone allows breeding with slow neutrons, which can be done with low fissile densities. Other than that, Uranium and Thorium have pretty similar characteristics and capabilities in advanced reactors.

I have no relevant knowledge or experience, and also not a lawyer to discuss it in any more details. But just small correction for you and others who might follow: such broadcast does not imply that both sides are involved in the actual transfer of money. In general case they are involved in the propagation of the transaction, and direct payment between two HAM participants is just one of the possible uses.

Google has been doing this with Google Photos since its inception, the only difference being that Google actually uses it (in my opinion) for good by auto-tagging and offering search across your entire life of taking photos.
You are describing a bubble, not a pyramid scheme. A pyramid scheme uses N people to pay for 1, and collapses when the supply of people runs out. There's no imagination that something's value is constantly increasing. A bubble uses one person paying extra to pay one other person, and collapses when people stop believing that there is a richer sucker.
I still see myself as a junior dev since I am still self-teaching a lot of stuff. While running my own business, working on projects with my customer.

I’m not a good dev. But I am good at working with others and getting stuff done. So, there’s that going for me I guess.

I probably wouldn’t be employable if I had to go through coding tests. But I can fix problems since I study and research a lot.
I'm not disagreeing, but I think the implication is that the bootcamps tend to leave their students without the fundamental knowledge to progress further in their career.

Not saying you need a full 4 year program and a CS degree. I don't have a CS degree, but 2 degrees in electrical engineering and computer engineering. That gave me a very solid and low level concept of computing that most CS grads dont get. Programming languages are a dime a dozen. Some are better suited for certain tasks than others.

Someone going to a Ruby on Rails or Node/JS boot camp isn't going to get that exposure to multuple languages. They're not going to know that, say Python is a better language/ecosystem than JavaScript for scientific analysis. They're not going to be exposed to C, C++, C#, Java, Rust or Go. Personally, I wouldnt even interview someone that's taken a boot camp in C or C++. The languages are too nuanced and complex to even get a foothold in 3 months.

Sorry this ended up very rantish, and I didn't mean for it to be so. I'm trying to make the point that while, yes, boot camps serve a purpose and may be useful to some folks, they will not and are not designed to give you enough knowledge to truly excel in the industry with the knowledge gleaned from the boot camp alone. It will take an extremely passionate and aggressive self learner to be more than a junior after a boot camp.
I'm only comparing what happens in the world we have, where Uber & Lyft exist, vs. what would happen if they didn't, or would've happened back when they didn't. Obviously some of this is guesswork kind of like "Gee what would've happened if I'd married my high school crush" or whatnot. But in general if you would've walked or biked to transit before, and now you take Uber & Lyft, that makes congestion worse. If you would have driven to transit, using Uber/Lyft has no effect. If you would have driven the whole way, it's a partial improvement (by riding transit for that one segment).
High school is a guided path, there are choices to be made but everyone comes out of it with a similar set of skills and knowledge. College is self-guided and people can choose the degree they want to pursue.

The problem today is that there are a lot of people who pursue degrees with little regard for the cost and the applicability of the degree they're pursuing. If they do that now, when they have some skin in the game, how will that improve if college is "free". I think you'll see more people getting degrees in fields that have no job market. Sure, they don't have debt (the rest of us will foot the bill), but they have no job prospects either.

The people I see on Facebook and other social media complaining about the cost of college and the job prospects they have all have one thing in common: they bought into the "pursue your passion" lie and came out of college with a degree that they can't use.
And, as far as deaths go, you can't get numbers for something you didn't count. No real accounting has ever been made of the number of people who got cancer and/or died from nuclear activities, starting with the activities at the Hanford Site on through atmospheric testing and today's nightmares like Fukushima.

The nuclear industry regularly uses this technique of "nothing to see here" to hide the fact that all nuclear plants leak and discharge radiation. All produce waste with an un-fixable lifecycle.

As far as your Wikipedia link, it was uploaded by an individual person. No references there.

Helen Caldicott is widely respected and far more of an authority on the subject that you or I or the journalist at the Guardian whom you cite.
No. Execution actually starts at 0x0 like most architectures, but the boot loader fits in the first 256 bytes, so after the last instruction executes, execution continues on at 0x100
U.S., Burma and Liberia the only three countries NOT using metric.
Juniors are great when their inexperience is correlated with youth, fresh outlook on the world, a burning passion for the subject, lack of fear with new ideas that seem controversial to the old guard, and frankly fewer family commitments such that succeeding at their job and learning and growing is their number one priority.

Very little of this applies to people on their second career doing bootcamps for a leg up.
haha games "journalism"
A self motivated person can break into CS but that's not what he's talking about. A 16 week class isn't enough to prepare a dispassionate person looking for anything.

The problem with these camps is they help those who don't need it.
how is that related to targeted ads?
> Yeah but there’s nothing physiological or neurological there

That's, IMO, an unwarranted (and, taken strictly, almost implausible) assumption. (Especially on the interest side.)

Also wtf should we pay attention to snowden's opinion. the guy is no "security guru". His name is only relevent because he uses it... so what?
Since BTC's security is dependent on hashing power, and you need money to purchase hashing power and run mining machines, the floor must be high enough that rogue parties cannot easily perform 51% attacks. If the price were to dip to say, $100, then the incentives for miners to mine for new coin would dissipate along with it. It would cost more to mine a coin than a coin sells for on the market. Presumably, network hashing power would drop until profitability was met. Problem is, since all that idle hashing power would exist, there would be a feasible attack vector to take down BTC. I can't venture to guess where that imaginary floor is without some in depth research and analysis, but I would guess it's got to be at least $1K if not higher. And it will continue to rise as the network gets more valuable.

I know that it's worked elsewhere, but that doesn't mean it will work here (without some cultural changes). I'm not saying college shouldn't be free - maybe it should - but I'm saying that the problems we have today with underemployment aren't going to be fixed by free tuition.

We first have to undo decades of treating trades as a lesser class of work, and telling everyone they have to go to college and "follow their passion".

I was under the impression that private collection agencies work on commission from the amount they recover. Is that not the case?
