Standford Class2go gives you half credits if you are late for all the quizzes and exercises but the final exam counted triple so you could skip a few things here and there and still work it out(you had to study them for the exams though!).

I love the fact that there is a due date, it forces me to do it and a certificate is very rewarding too (I tend to give up the courses that give me no "credits")...

I think in general,the schedule are too tight though.
I doubt that is the case in any great quantity. Many investors who buy gold do it because they think it is somehow safer than "paper money". They don't like to buy "paper gold" and that's why the biggest gold ETF (GLD) stores physical gold.

That said, there is of course a gold derivatives market. It seems to be rather small according to the survey cited in this article: http://www.ft.com/intl/cms/s/0/eb342ad4-daba-11e0-a58b-00144...

Also consider car dealerships where there is all sorts of special regulation, and even prevention of manufacturers selling direct to the public. (See litigation against Tesla for more details.)

Heck in California (I don't know about other states) the sales tax is paid based on the purchaser address, not the address where the sale takes place like for other goods.

Is this supposed to be a joke? I thought JetBrains was going to make a newsreader, but at the end of the page it says:

"Sounds great, doesn’t it?
We’d sure use a newsreader like this.
If you think so too, share this page to add your vote!
Hopefully someone listens and makes a proper newsreader for all of us soon!"
I would say no, because the cost of digging it up again is very low and it's going to happen eventually.
Because this is the price required to make the profit they wanted to make on the 60kWh option.

The fact that some cheap low performance version turned out to be infeasible because customers prefer expensive high performance version doesn't mean that you should (or could) reduce price of the expensive version.

Furthermore, some owners of crippled 60kWh units will probably end up paying for "upgrade" to 60kWh. In the end these units will sell for full 60kWh price even though the buyers initially wanted 45kWh version.

The sad, harsh reality is, no one would hire Steve Jobs today or almost no one.Why?Because times have changed (In a bad way).We live in a world full of arrogance, stupidity and ignorance.We no longer think how to change the world but how to make a lot of money.

Steve Jobs was a non-technical guy.We have 1 million topics on HN bashing these guys for 1 million reasons.Even on this one we have engineers talking about the same thing over and over.

How about being realistic at least once. We do not give these people any chance of working with us.Because we are so arrogant these days that we think the world belong to us and only we (programmers/engineers) can change it.

We cannot find a Steve Jobs when we are not willing to risk at all.How many of you helped a non-technical guy building a project without asking for a huge amount of money or 100% equity?Probably not many.Most of the help consists of telling the guy to find a cofounder or to quit the project.Not one programmer/engineer would say "hey you know what, you're crazy but I'll help you" or any other similar line.

The truth is we do not own the world and we are not all-knowing. We can be all-star programmers and yet have crap ideas.Nothing is set in stone.Someone out there is always better than you.And history shows us that small things count. Unbelievable things come from unexpected places.

I am not saying that every non-technical guy is a Steve Jobs because I had my own failures with these guys and yes, it's incredibly frustrating.But those were bad selections.A risk I was willing to take.I helped a non-technical guy with a startup 4 years ago.He had a weird idea and he asked me to help him in exchange for a fixed sum of 350K. He came to me with a damn paper and pen to talk about his idea. He had no money to hire a programmer only an ambition that could move mountains.And after 6 months I received the money in my account...the startup was a success...and that's when I changed my mentality.

So in conclusion, if we want to see a Steve Jobs, we have to take risks.Otherwise let's continue flipping the coin and wait for it.
Absolutely. People who add complexity to software development neeclessly have it completely backwards.

maybe i did not make myself very clear.

i tried to address the analogy which is implied by these two points. and it is true, that for coffeescript on javascript, coffeescript is not more constant and js is not more variable. but that's not the point of the argument javascript were the assembly of the web. the point is, that all these languages compile down to js. as c and c++ compile down to assembly.

and honestly the "c is constant" is not right some of the time either. consider small/big endianness, different libcs. heck, even the syntax changed (k&r surely looks and feels different).

my comment on simd instructions to assembly was an analogy to asm.js and javascript.

"making arguments based on metaphors rather than the thing itself is a classic trap"

Well, yes and no. I do agree that it often goes completely wrong and can be very misleading. But the JavaScript/assembly argument is more an analogy than it is a metaphor, and analogies are a very important function of intelligence and a tool for making important discoveries.

That said, I like your generalization "compile target" a lot more than calling JavaScript assembly.

It is absolutely true that everything about 2013 is superior to 2007 for SaaS businesses, with the debatable exception of the amount of competition in any niche/vertical. It is also true that the best time to start a SaaS business for the 2013 market was 2007 (or as earlier as you can push it). You get a head start on the learning curve, which is formidable, even with lots of people generously sharing what they know about customer acquisition, technical topics, etc etc etc. It is virtually impossible to read your way to scalable customer acquisition (or any other very worthwhile business goal). Past the high-basic/low-intermediate level you have to put things into practice in your own business and see how they work out. In 2007, virtually anybody doing that was breaking new ground for the industry. In 2013, only most people doing that will break new ground for the industry. It's ridiculous how much we don't know yet.

2018 is going to be superior to 2013 in pretty much every way, but don't wait until 2018 to start, if you're on the fence about it.

I'm very familiar with this game, but I've never played it! I randomly found a channel on TwitchTV where someone was playing it and had a really active commenting community. I watched him a few times in the background while I was doing something else, and even commented a little. This was months ago. Perhaps he was playing a beta or something. It baffles me slightly that now this is on the front page of HN but I love that there's that join-up with a coincidental channel I watched. What a funny age we live in :)

Google treasure maps, april fools prank
I suspect gold will prove a lot harder to manufacture than diamonds.

Gold is created in the explosion of a large supernova that was formed from the remnants of generations of supernova before, each explosion creating heavier and sometimes totally different elements.

All the Silver in the world was formed in a different chain of supernovae to the one that formed all the Gold in the world.

(A fact that blows my mind when I think too hard about it.)

http://www.world-science.net/othernews/120906_silver.htm

Diamonds need carbon and a fast-moving object to strike it. They are therefore relatively common and relatively easy to make. There is one meteor crater in Russia that contains 3000 years-worth of diamonds (at current consumption rates). It is considered uneconomical to mine for them.
I noticed an uptick in hellbanned after the PyCon incident. It seems several otherwise rational individuals turned into violently woman-hating psychopaths during that whole debacle.

I agree with many of your points but the main reason I use Coursera is because it's an actual course, with structure and quizzes and assignments. I personally find Khan Academy to be useless, and I've tried to use it (Edit: useless for me, but I do think what he has created is fantastic). I think I would find it useful as a supplement to an existing course, and that's what it was originally designed as. Very few people learn anything of moderate complexity without doing exercises throughout.

Another quite interesting article on gold - http://www.telegraph.co.uk/culture/qi/8667421/QI-Quite-inter... - points out that electronic equipment is actually one of the best sources of gold nowdays. One ton of electronic scrap yields more gold than 17 tons of gold ore.

There most likely is. Even when the USD was on the gold standard, there were far more of these gold claim certificates we called dollars than the US had in gold reserves. This is the nature of fractional reserve banking, and it no doubt still takes place with gold.
It's also recycling's greatest success story. Think of that. While other resources are consumed, gold isn't, and it's far from useless. It's simply more useful, at the price, at being a store of value.

The longer quote from Warren Buffett is very interesting

Today the world’s gold stock is about 170,000 metric tons. If all of this gold were melded together, it would form a cube of about 68 feet per side. (Picture it fitting comfortably within a baseball infield.) At $1,750 per ounce – gold’s price as I write this – its value would be $9.6 trillion. Call this cube pile A.

Let’s now create a pile B costing an equal amount. For that, we could buy all U.S. cropland (400 million acres with output of about $200 billion annually), plus 16 Exxon Mobils (the world’s most profitable company, one earning more than $40 billion annually). After these purchases, we would have about $1 trillion left over for walking-around money (no sense feeling strapped after this buying binge). Can you imagine an investor with $9.6 trillion selecting pile A over pile B?

Beyond the staggering valuation given the existing stock of gold, current prices make today’s annual production of gold command about $160 billion. Buyers – whether jewelry and industrial users, frightened individuals, or speculators – must continually absorb this additional supply to merely maintain an equilibrium at present prices.

A century from now the 400 million acres of farmland will have produced staggering amounts of corn, wheat, cotton, and other crops – and will continue to produce that valuable bounty, whatever the currency may be. Exxon Mobil will probably have delivered trillions of dollars in dividends to its owners and will also hold assets worth many more trillions (and, remember, you get 16 Exxons). The 170,000 tons of gold will be unchanged in size and still incapable of producing anything.

You can fondle the cube, but it will not respond.
