(Note: we have a block schedule; not all classes meet each day)

The reality is that in a typical 1-hour class with 5 minute breaks between classes on a big campus you lose the first 5 minutes of class to people arriving late and the last 5 minutes to everyone packing up their books so they can rush our the door. So you get 50-minute classes, or about 5/6 of your nominal instruction time. And if you have to do a lab or something, you either have to do double-period classes or stick to labs that can be effectively completed in 40-45 minutes (because you need time to set up and clean up too).

So enter block scheduling: the idea is to lengthen the classes to 90 minutes or so and alternate days when they meet. You still lose 10 minutes of each class, but that's 8/9 of your nominal instruction time, not 5/6. And teachers get a bit more flexibility in terms of what things can be done with a class. The drawback is that if you lecture for the full 80 minutes, the outcome is typically not so great: it takes an exceptional lecturer, or an exceptional student, or for some sorts of material both, to pull off someone still being able to absorb information in a lecture that's longer than an hour.
Looking back at what I wrote I can understand your reaction - im wasnt trying to propose a new solution that someone hadn't considered. It was more a question of why couldn't it be that, which you answered quite well, thank you.

Bill Gate's answer was " You mean an API that you have a patent on?"

If the lawyer had said "Yes", he could have answered "No": Gates knows that patents don't really apply.

Otherwise the lawyer would have had to define it, which runs the clock down on how long Gates had to actually answer questions.
I never said it took away from the good. I said that the damage he caused doesn't disappear because he is doing good.
Neutral hydrogen in space is actually quite readily observed via radio telescopes as the famous spin-flip 21cm line. This signal has been very useful in mapping the distribution of neutral hydrogen within our own galaxy and those of our galactic neighbors.

In addition to this, there exist many arguments in favor of classifying normal matter and dark matter separately.

It's still vulnerable IF they can push a solid product that looks modern and offers many of the things that existing products offer, but that will require a pipeline of product managers and docs/nurses who already know the landscape because chances are, picking up developers already in this field will get you more of the same quality the industry has to offer.

Okay, not TOTALLY their fault. Programmers != designers necessarily, and designers are sometimes have their hands tied legally, but 2k line functions? Ugh.

"The system is working exactly as it is meant to.."

Oh, I don't doubt this. I just wonder if the "meant to" part means representing the will of the people and acting with the interest of the general public in mind.
Object thinking is actually a word (and also a book [1], but that is less important); and I agree. A definition of OOP and FP that focuses on how programmers are guided to solve problems would be much more useful. With OOP, you think in terms of objects and their interactions (names and naturalism rule). With FP, you are supposed to think more about the math of the program's universe (structure and equational reasoning rules), or maybe its just about the verbs and processes (for less pure styles).

Interesting. I sit, but I get up a lot and run around with the dog, etc. I wonder if standing really would make a difference in my case. I could imagine if you were working in an office all day, it might be a problem. Though I wonder if standing too much has its own troubles too. Maybe thats why the desks that easily go up/down would be nicer - that way never too much of one thing - standing or sitting.
How does this differ from what Google did with Android, effectively leading to "Java apps that can only run on Android"?

Microsoft was a Java licensee, and Sun claimed the license required them to implement the standardized Java interface. Sun sued over the license and antitrust issues.

Google isn't a Java licensee. Oracle sued over copyright issues.
It really depends on the class.

Lectures of any sort longer than an hour are pretty painful. Science lab classes shorter than an hour are likewise pretty painful. Designing a schedule that can accommodate both is not easy and people typically don't even try (though they should!).
Hey, glad to see you're here. Let me clarify.

As humble as your position is, I'm trying to say that you should be proud of your success, because there is probably good reason for it. I'm not one to tell you whether you actually believe that or not, but I would suspect it to be true.

But, I do totally agree about "quick tips, todos, or silver bullets". Regardless of that, I'm sure there is something reasonable special about you that has driven you in particular to create at least three moderately successful businesses. Something we could probably learn from.

You're missing an important fine point here: I am not advocating buying options. These strategies are selling options. So implied volatility and theta decay are your very best friends.

This "options are too complex" language is just silly. Retail investing doesn't work as it's been taught! It underperforms the market and professional investors, and it doesn't have to. You don't have to run complex positions, selling a vertical spread is every bit as easy as buying stock (one transaction to open the position, one to close it, and sometimes you don't need to close it.)

Anybody who wants to tell me options are risky has to explain this: Suppose you want to capture upside in, say, Amazon. Why is it riskier to sell a put spread or buy a call spread, in either case risking just a few hundred dollars, than it is to buy shares when just 25 will cost you $7500 or more?

The fact that you mistook the value of theta decay and IV in my proposed scenario of selling a covered call makes me think you just don't understand some of these things. And that's not your fault, it's a huge fail IMO that the retail investor has had to learn the finer points of front load vs back load on some overpriced mutual fund but has been taught that options are scary.

Again, I do not advocate for taking long option positions and I definitely think you should check out TastyTrade.com to learn a bit more about the philosophy.
It is, plainly, a fairly stupid gimmick.

Hackers, engineers, and those of like mind should (and do) think about things honestly, not positively. Nearly every breakthrough you read about in the news is simply bunk.

If you didn't have this attitude, you'd be fairly disappointed because dozens of times every year cancer is cured, batteries increase capacity by 50%, cheap fusion is almost here, somebody's figured out a free-energy machine... on and on and on.

The world is full of scams, gimmicks, and overexcited news outlets (and self promoting individuals) touting breakthroughs in every field. If you get excited about each one you start to look foolish really quickly.

Some truly exciting things _do_ happen from time to time, but we're pessimistic (nay, realistic) about so many things because that's just how the world is.

Thanks for pointing this out. I've owned several Leicas, including pre-M models, IIIc and IIIf. Among M Leica cameras I once had an M-3, and have owned an M-6 since the 1980's ("Classic" according to the article).

Like many photographers, digital has been the medium for over a decade and haven't touched film over the last 10 years. When I see reminders like this article, I'm enticed to get the Leica out of storage. One of these days, I might even take some pictures with it. I do enjoy using the Leica lenses with my Olympus EM cameras in manual mode, it's great fun.

I agree with the comments that digital and film are distinct image-making methods. And because each has its unique esthetics, they really can't be compared. It's rather like oil vs. acrylic painting, one's not better than the other, just different, its own thing.

A store in town sells only film equipment, mostly used. I've visited the place often. One time I asked the owner about his customers thinking they were of more "mature" vintage like me. However he says most of the interest is among people under thirty who regard digital as "old hat".

Interesting. It makes sense though, artists still use oil paint (about ~700 year old technology), and egg tempera (>1000 years old), among many processes. On that basis it's safe to predict film will never die.

Though I'll likely never use it again, I'm glad film is still an option. With any luck, some day my M6 will again come alive, no doubt held by a photographer about as old as the camera itself.
They obviously have all sorts of quality metrics. What exactly do you mean? Driver density, time to pick up, time to deliver, routes taken, feedback ratings, car quality, etc.

No, it's not. If you read the exchange posted by the parent poster again, it's about MS's additional API hooks in Java that were meant to be used by Java developers, so they're definitely not undocumented.
I don't think the incentive structure of mining is fundamentally tied to a "currency", per se. A tradable asset of some sort, yes. But that's arguably a much lower bar to reach. (For instance, a Starbucks gift card makes a perfectly good tradable asset, but not a fabulous currency.)
Depends on the quality of the runtime. For instance, C# and Python are really good and well-documented. Your Java environment can vary quite a bit, but you probably have control over it.

Howlers like PowerBuilder and InstallShield are just hopeless amateurville and leave me giggling with awe at how fantastically bad they are; they are worth looking at if you want to get a sense of how lucky you are.
I like to stand while working, not alternate between standing and working. Pacing helps me think, and not having to sit down to use the computer each time I want to try something while working my way through a different problem is wonderful. Finally sitting down after finishing something that's taken long enough for my legs to get tired is pretty satisfying too. With a motorized desk I find I usually spend a bit under half the day standing.

For me, any long term health benefits from a standing desk is purely a nice bonus.
As I recall, Uber was picked up quickly in San Francisco. I recall Mike Arrington raving about it when it first launched. It had instant uptake in tech circles & early adopters.

Facebook was instant in the fact that when launched it took Harvard by storm and then grew like a weed thereafter.
They're different communities, with different standards.

I took a Lyft recently from a driver who had an excellent rating. He happened to also be an UberX driver and confessed he had almost been kicked out of Uber because he was getting bad ratings. All his feedback was along the lines of "driver is too chatty, tries to make unnecessary conversation". With Lyft, the whole point is that your driver is friendly and makes conversation.

Uber drivers seem to be strongly encouraged to offer water and gum where only the occasional Lyft will have either.

There are a couple other small differences but yes, drivers and passengers select which community they want to be a part of. Depending on which aspects of each you prefer, the qualities definitely differ.

Miners don't choose whether to mine based on whether the network is secure. They mine if it will be profitable to mine.

So we can expect the total cost of mining to be approximately equal to the total block rewards plus transaction fees. The more valuable Bitcoin becomes, the more valuable those rewards will be, and the more money will be spent on mining.

Some percentage of the mining cost will go to energy, and the rest to hardware. So it's possible to estimate the energy cost of mining at various price levels and times (since block rewards decrease over time).

Ignoring transaction fees, it's actually not terrible. I figured out a while back that it would be something like several gigawatts, if Bitcoin became a trillion-dollar currency in twenty years. But if transaction fees become significant it could get a lot worse. (Luckily there's some work in progress that could increase scalability enough to keep the fees low.)
It's a shame that Skurt didn't include their social media links on their own site.
I don't think it's a good idea. People don't really shop around Uber, Lyft or Sidecar. Most people make their decision to use one predominantly or exclusively. Same with drivers. People aren't going to Kayak through every $5-20 decision to save a buck. Especially when there are other important variables and brand promises.

And the premise is a little insulting in that I'm supposed to feel like an idiot for having picked one provider.

That's why most who have seen some success would say (or so I have heard from their mouths):

"The more you try, the luckier you get".

There may be an element of luck that may affect to a significant extent (think lottery) without or having little attempts but in the long run it pans out.
This highlights not only the importance of sticking it out, but sticking it out long enough, even after getting smashed many times over.

But of course, there has to be a specific and unique insight as a starting point, ala how can you make something better than whats out there now?

Its not surprising that people whom are passionate about their circle of competency, those who would venture in all directions from their initial locus/loci, seemingly random areas would pick up observations that others miss.

And only those with a genuine passion and interest will continue sticking out, even in the darkest times.
I've started reading the book, and it's an interesting read. I'm very, very interested in cryptocurrency, but he hits a lot of skeptical notes that resonate with thoughts I've had. Bitcoin is an awesome technology, and it's easy to accidentally assume that it must therefore also be useful and valuable. Unfortunately, those are actually three separate questions. Plenty of things are technically cool but not useful, or useful but not profitable.

Personally, I think there's a serious chance that cryptocurrencies will disrupt (in the original sense) a lot of economic and organizational systems, but I also think it will take a lot more than Bitcoin to get there.

EDIT: Probably worth saying that I don't unreservedly endorse the book. There's more than a bit of misunderstanding, exaggeration, and hyperbole. But it's a useful counterweight to the hype.
It might not be applicable anymore, as the compiler optimizations become more advanced to the point that it is hard to predict the translated machine-code. This is one of the most important points with regards to tool-chain specific knowledge. The other is proper usage of the debugger.

As one of my colleagues once told to one of people like you, "I celebrate your existence because it guarantees my job security".

Do yourself a favor and study what you're actually interested in, seriously. Avoid places where you have to or even can coast, because it wastes your time and gets you used to wrong things. Also, such positions are usually dead-ends career-wise.

/* To tell the truth, I spent little time in university classes because they were too slow. I learned the same topics, and some more, myself, and worked a lot with professors on actual research. So I had pretty high [equivalent of] GPA and graduated well without much 'coasting'. */
It's utterly amazing what nationalism can cause people to do and say in the face of criticism.

It's also very disappointing that, for quite some time, Snowden was labeled a "traitor". Even now, although the polls are showing that the majority of Americans surveyed state he is a whistleblower and not a traitor, that what he did was bad for, or an action against, America.

If what Snowden has said is true regarding the level of access he had when working in the CIA, then it is absolute proof, if any more is ever needed, that his actions were taken in the interest of the public and not himself, and especially not against America.

It's likewise very disappointing how little has come about as a result of what was shown by his leaks through the Guardian.

Besides that, the customers buying their flag-ship product will find it useful to buy this product alongside

Is the reverse of this also true? That is, is your competitor's (new) product _less useful_ if I don't have their flagship product?

Is that a large enough niche for your to be targeting?

Is there a big competitor to their flagship product? Could you target your product at companies that have chosen that suite?
my dad used to 'cheap-out' as i'd call it for most of my life, "why waste the money?" he'd say. Now in his later years he buys luxury - a new boat instead of fixing up the old one, a 'comfort' car instead of something that fits better to function, etc. His reasoning now is, "I've got the money, I might as well enjoy it cause I can't take it with me when I die. A bit more money for me not having grief is well worth the investment." Like your statement, it has nothing to do with envy, he'd just rather splurge a little to have the piece of mind that what he has is going to work in the way he wants it to.
I'd love to see a pragmatic play in the FP space.

A related quote attributed to Orwell: "In a time of universal deceit, telling the truth is a revolutionary act"
Yes, Bill Gates answer was the question I was referring to as a good one. My formatting of the quoted content was a little messed up in the first line.

>If the lawyer had said "Yes", he could have answered "No":

No to what? The original question was whether Gates was indifferent to developer usage pure vs. proprietary APIs.

This was an attempt by the lawyer to color the APIs as proprietary while asking about pure Java vs. Microsoft's API functions and Gates wanted to know exactly he meant by that term before giving an answer to the question which could imply that was agreeing with the lawyer that the API was "proprietary", which could mean different things to different people.

It's like a lawyer asking "Do you like the brand of the beer you stole?",

The proper answer is "What do you mean, stole?".

Not, "No, I don't like Budweiser".

I took traning like a decade ago to become Epic systems admin. They use Caché database, a hierarchical db. MUMPS and visual basic are a couple of languages they use.

Kaiser permanente is a big customer of Epic. At one point, Kaiser wanted equity in privately held Epic systems, because Kaiser thought it is the market maker for Epic systms. Epic systems did not budge to Kaiser's demands.

Unless salesforce comes with a solid product to compete with Epic, no big hospital would buyt Salesforce product. If I were the decision maker, I would rather go with a product that can be successfully implemented; otherwise, I would end up loosing the job like those bad $1B SAP implementations.

What is the impact of cloud in healthcare EHR. Not much, healthcare is like banks, finance. Lots of regulations like HIPAA, audits, etc.

Yes, Epic and non-epic systems can be interfaces via HL7, which is like XML.

When banks move to cloud, thats when we expect healthcare IT to move to clound. Until then, it is gonna be in the datacenters managed by hospitals.

Almost everyone in today's world confuses love and attachment. They misunderstand love as attachment, and attachment as love.

However, the term love contains a very important meaning. We can't say that we really live properly as humans without understanding what love is.

That's why I'd like to ask you something. I hope you don't mind my question. When you say "love", what do you mean by that term? What do you indicate?
There are plenty of mature pragmatic FP languages out there, like OCaml, ML, F#, or even a disciplined subset of Scala.
