Interesting article, however it seems to suggest that these 'Smart and social' people are not on equal footing when it comes to intelligence as the 'Smart and not social'.

However your box graph suggests they are.

The points you make a good and solid but it doesn't really bring out as to why the perception suggests there are many less 'smart and social' people than 'smart and not social' people
Hello world and hobby projects are not the target for the JVM. It may take a good chunk of RAM to fire it up at all but you can serve far more clients in that same chunk than you could with the number of Ruby processes, for example, you could run in the same memory. Look at how much more performance Lift/Scala can squeeze out of the same box than Rails.
I disagree. You can make and download and share stencils. There are great sets for different UI systems...

What am I missing?
deGrasse's observation was that when a scientist reaches a point where he can't explain, or understand something often he attributes it to God... And then years later someone else find it's explanation, until he stumbles onto the next problem.

It's all good. I gues it's okay to put God where your knowledge limits you, or the current more wide one, but just don't spread it that it's because of God.

e.g. God is "what we don't understand"
Let's say for the sake of argument that a typical congressman CANNOT represent 20,000 people.
I like the message - more innovation please. But the article contains some questionable passages. For example:

"Both wind and solar technologies require tremendous capital expenditures before they can be brought to the market and scale up to production. In contrast, a radically improved internal combustion engine could be easily produced with existing industrial capabilities and quickly dropped into the global car production cycle."

This seems to indicate that the author believes that a radical design change could be easily produced. But who's to say that a radical design change wouldn't require radically different capabilities? And as far as I can tell, the ICE has definitely seen improvements in efficiency not only in years where there was government involvement. Sure, it hasn't been "disrupted" with another technology, but that doesn't mean there is no innovation.

And what exactly is a "sexy technology"? How would a radical development in ICEs be less sexy than a radical development in battery tech or solar, or computing?

Uh. He didn't say that. He said that getting Balsamiq gratis meant something important to him, and that and Balsamiq itself (which is so much more awesome when you actually use it than you'd think a mockup tool could be) kept him from getting discouraged while building something.

This post put such a smile on my face, but then I read the comments and it's like, here's the guy who doesn't believe the letter, and here's the guy who sees this as an opportunity to harp on Adobe AIR, and I'm afraid to see what the next nasty comment is going to be.

Programming Interviews: What to Expect
TLDR: JVM uses too much memory for little/hobby projects.

Response: Learn to manually configure its memory useage, don't just go with the default.

Not really front-page worthy.
I am quite sympathetic to the deadweight loss arguments in this paper, but placing the blame on the trolls is a bit misguided. They’re responding to incentives, even if we don’t like them. I wish the paper were more oriented around the law and the practices of the patent office.

Also, again while sympathetic, this paper was clearly researched after the authors had taken a position on the issue (notice the book mention). They started with a position, and went looking for data ex post facto.

They make no distinction between more and less legitimate patents. If a company is infringing on what many of us might consider a legitimate patent, then yes they will suffer financially. The paper elides over such a distinction.

Using stock price as a proxy for future foregone profits is clever, but it’s a heck of an assumption. I don’t think it rises to the level of empiricism. It’s interesting for sure, but best understood as a statistical artifact.
I've run into lots of headaches trying to run multiple apps in the same container. It's been a while so maybe this has improved over time.
I've always wondered about the sales ratios of iSomething+ versus the other two. It seems to be that most people either want the cheapest, or the best, and that the mid-range exists primarily as a stepping stone to convert the former buyers into the latter.
I feel like the JVM has already proven its self to be viable as a production VM. The 'helloworld' argument doesn't really hold water because you would never run helloworld in a vm. If you care about fast setup/teardowns or small memory footprints then don't use ANY vm. If you want things like easier security policies, garbage collection and maybe more the point: scalability then the VM is a great platform to develop for.
Completely agreed! Thank you for checking out Quipol :)
Can you throw up a hello world project on github and tell me which arguments to pass it to get the memory lower? I've tried, but maybe I've missed something.
This is the kind of comment you write when you've never actually used Balsamiq. I use and adore OmniGraffle (though I'm back to doing more technical illustration in Illustrator), and it is nothing like Balsamiq. It's not a difference of stencils or downloading or anything like that; they are simply very different applications altogether.
There are some excellent example pages here. We had a lot of fun reading out selections from http://fleshlight.couponzor.com/

Have these companies signed up, or did it just seem like a particularly good idea to use Fleshlight as an example?

All of the most special people in history endured many failures. So while failure can teach us many things, "you're not special" is absolutely not one of them.
Well, except for the part where calculating income is still as difficult as it was. Somehow, I don't think the piecewise linear function that is progressive taxation is the cause of the difficult parts of the tax code.

While I see his point regarding excessive memory usage WRT the JVM, I don’t think this matters much. The fact is memory is cheap these days and the convenience of the JVM is something that’s tough to overlook. Furthermore, while a Hello World app may require 100MB when implemented on the JVM, much of that is overhead which will stay relatively constant as your process grows more complex (to a point, obviously). I can run multiple processes on the same JVM instance and stay within reasonable memory bounds.

Also, we need to consider the alternative. Where would we go if we didn’t have the JVM? It’s not like .Net is much better in this regard. We could go without a system as heavyweight as these two but then we lose all the advantages that come along with that weight.

Certainly, those advantages are not needed for a lot of purposes. Looking at what he’s running I would say he probably doesn’t need the weight of the JVM.

That said, I’m pretty sure I couldn’t do my current project anywhere but the JVM (well, okay, they’re all Turing machines so technically I can, but bear with me). I’ll gladly fork over the cash for a beefier VPS if it that’s the cost of the JVM.

Full disclosure: I am considered a Scala evangelist.
@tptacek nailed it on the head. It wasn't a rational thing. It was emotional. All I'm trying to say is that Peldi's generosity affected me in a huge way. It was a tonic—a positive starting point that I've cherished ever since.
I don't think this started with the internet; the internet just made collective consciousness vastly more efficient. Just as information is processed algorithmically within the brain, information also passes from person to person via language, print, technological invention, etc.

We all want to believe that our consciousness is fully independent, but it's pretty hard to separate from our memetic history. Perhaps someday we'll be able to wire our brains together physically via wetware, and our philosophical questions about individually will take on a whole new level of complexity.
Due to the way the flashes scatter among the clouds, I'd say that they are lightning contained within thunderheads/conflicting air masses.
The JVM is the one part of Java that is actually Gaining more mindshare. Granted "hello world" is not the ideal usecase - but you are missing the point. The cost you pay for hello world still remains the same up to a moderately sized app, and the more the complexity of your app, the more benefits you start to see from the JVM's memory model.

A better comparison would be a real world app that scales to a number of users - tell me about JVM memory usage and performance then.
Looks like lightning.

You want to develop a server app and 100MB required by container is your concern? BTW This is year 2011 not 1996.
No, its true.

The Constitution originally let the states directly appoint senators. That gave state governments more power than they have now.

The Constitution also originally prohibited any taxes that were not proportional, making direct taxation of citizens very difficult. But when that was thrown out, the federal government was free to grab a huge percentage of your income.

Money is power. Now the states have to kiss up to the federal government to get money.
Yup, JVM takes up huge resources. But, when you put the app in production, you can be rest assured it will perform. JVM gives you piece of mind.
I guess you should just run a golang HTTP service behind nginx if memory is your biggest concern.

If that's not good enough go ahead and write the whole thing using C. You can get one hell of a small "Hello, World!" program using C.
This is certainly true when you have to scale at some high level, but I think that level is a lot higher than most people realize. I worked at yellowpages.com for a while and we were serving a large amount of traffic (the local ads on bing are from yellowpages) with native ruby. The JVM may have been a better option at that scale, but the vast majority of sites won't reach that scale. And ruby handled it just fine. The actual search logic was run on the JVM though.
Yes, Java uses a lot of memory. It uses a lot of memory mostly because it doesn't mmap static shared lib files. Most c library based systems (e.g PHP, Python, Ruby) do. When the system can mmap read only shared lib files, that uses a lot less memory because multiple processes can share them and they are only read in to memory as they are accessed thanks to the page fault mechanism of 386 protected-mode architecture.

Java can't do this because Java self-modifies code (JIT) to run faster while it's running. Once all your classes are loaded into ram though, the memory gets consumed at a much more leisurely pace. However, multiple apps can't reuse each other's already mapped into memory code like they can with PHP, etc. As far as appserver restarts, just pay the money for JRebel already and quit complaining. Your life will be so much better.
Apache Mahout: Scalable machine learning for everyone
If you’re launching your hello world project in the CLI, you’d just add -Xmx=64m or whatever size you need. 64 tends to be the default and I haven’t personally tried pushing it lower (for my work I actually have to push it up into the 3-6G range. Ah, language processing).
Oh man, that's hard to hear. I'm sorry that it comes off that way. While building Quipol, I was more of an onlooker. Maybe I should have been more active earlier.

Okay, 94 points and still no comments, I'll bite.

I think the difference here is, and I don't think this is a subject that has been thought about quite enough, is that mathematics typically describe calculation, while code describes a superset of calculation, computation.

When we spend all our time working with the more expansive set, computation, we sometimes forget that calculation is in many ways less expressive and has fewer ways to express a thing. Many of the ideas in the article seem to be about getting over things we take for granted in computation, and understanding how to operate in the more limited framework offered by calculation, and/or understanding that even if things look kind of alike (what's a good word for this concept? a homoscript?) in computation vs. calculation they can be subtly different with a range of pitfalls.
On the JVM it will take over 300MB with JRuby. A simple 'hello world' servlet on the JVM takes over 100MB (once you hit it with a little traffic).
The point is that it is too expensive RAM-wise to even serve as a gateway drug for hobbyists to venture into more serious JVM based projects.
Really fun reads. Great to give to people who think anything 'sciency' is stuffy:)

That doesn't mean they can't be arrested and charged with crimes they commit while in office, as long as the arrest and trial occurs after they leave, does it? Indeed they could even be charged in between sessions, couldn't they?
Try it, I did. I can't get a servlet to use under 100MB after getting hit with a moderate amount of traffic. It runs out of heap.
I'm also a huge fan of Peldi - I love that he personally responds to emails and tweets and seems to actually give a shit about his customers. (Very refreshing after my stint at Google, which is severely lacking in that department :).

I also love Balsamiq - I use it both to prototype web/mobile apps and also for diagrams in presentations (http://client-side-apis.appspot.com/). The sketchy feel makes the prototypes feel more flexible, perfect for encouraging iteration.

I've been using myBalsamiq (the online version) for a while, and though it is Flash-based, and Flash is the devil, it works pretty well and I recommend it.

What Bill Gates Says About Drug Companies
The JVM (at least the Oracle/Sun version) has some scary seeming memory allocation policies. One of the biggest offenders is its complete unwillingness to ever shrink the system allocated memory, even if the heap is 95% empty. For instance, if your application has a huge peak allocation period (whether your fault or an issue with soft references sticking about when you really don't want them), it will put memory pressure on the OS for the rest of its (process) life. If the JVM has an option of garbage collecting large amounts of objects or growing the heap, it generally prefers growing the heap. You can run quite a few Java applications with amazingly small heaps at everything will be fine (except for performance due to GC overhead).

The abstraction breaker here is that your application often has a set of ideal GC settings, which need to be set. You cannot forget about the garbage collector when using the JVM.

I'm inclined not to believe you, if you need someone to argue with you that OmniGraffle has a similar approach to UI mockups.

Perhaps you downloaded it, dragged some things onto a canvas, and then never picked it up again. You missed a lot of great stuff. It's a thoughtfully designed (and very nerdy) app.

This would be a mostly ineffective and impressively devious way to increase ad bids when Google could just, you know, refuse to fill orders at prices below a reserve price chosen to maximize their own revenue.

You know they do that, right?

AdWords is not an auction. AdWords incorporates an auction-like mechanic in part of its pricing strategy. There are numerous other ingredients in the secret sauce. We don't know what they are, but some of the public ones are explicitly chosen to make understanding auction mechanics less lucrative. (That one is called "Quality Score", which is a wonderfully Orwellian coinage for "Maximizing Google Revenue Heuristic.")

In an auction you are competing against other bidders. On AdWords, you are competing against Google. In aggregate, Google is winning.

(n.b. I like AdWords, but it would be an impressively bad time to assume corporate fluffy-bunnyhood when managing one's AdWords account.)
A blanket statement for a fairly specific use case seems irresponsible.
Agreed all the way. The fact that you can email him and expect to hear back is too cool.

I've used Balsamiq for design projects, too. It just feels authentic.
I can't agree with you more, on one hand the technical detail is somewhat increasing in American shows, but the over production and gimmicky nature certainly overshadows it. I'm always impressed by the technical level of BBC shows in comparison, but the best content is online, usually in lectures, and not TED.
We don't have civilian super-sonic flight or manned space flight anymore. I'd say in some ways we're slipping backwards as far as technological progress is concerned. Progress in energy technology is particularly pathetic. Nuclear energy was discovered in the 30s and no significant new source of power has been developed since (Solar isn't significant).
I had a very similar experience with the Balsamiq crew. Early on I didn't have much to offer other than this budding Web testing service I was working on. As it turns out, they have a Web site and saw value in it and accepted my barter offer. I was completely shocked. The outcome was two fortified notions: it never hurts to ask and the Balsamiq guys are great.

The author is falling victim to the Confirmation Bias. There are only two experiments, yet the author is content to over-generalize and conclude that "no matter what price we choose, we always make the same revenue." Why not reduce the price 3/4? Increase it by 50%? Increase it by a 100%?
Burner superfast 2.0
I think you kind of missed my point, for example if you are on the cc list for a series of emails that you are not directly involved in this strategy assumes that instead of you taking responsibility for catching up on this interaction when you return one or more people that are a part of this interaction need to take on that responsibility for you. This is effectively making them serve you in order to have your attention after you return from vacation.

That strikes me as casting yourself as more important than everyone else (not with respect to the interaction but as a person and/or employee).

I've seen that statistic as well, and wondered if someone would point it out when I wrote that. Apparently it's more than the Tea Party, for all the media bullshit about the two.

At any rate that's still a large portion of it unemployed, being around a quarter, compared to the population-wide unemployment rate of 9%. And surely you would find overrepresented among the movement folks who are underemployed or otherwise frustrated by the lack of mobility in the current market. So (I think) my point stands.

Great comment:

You can allocate as much or as little memory as your application needs. I run many personal web projects on a JVM sitting on top of a free-tier AWS EC2 micro-instance. I have tomcat6 instances running with <32MB footprint.

Perhaps you need to better understand what you're putting on the JVM and why it needs what it does
My memories of "Web2.0" began with the heavy use of AJAX and the design decisions that went with it. Such as creating websites that behaved as applications.

I'm not saying that Web3.0 is an appropriate term. I just would have preferred that a more general term was used to describe all the technologies as a whole. Referring to all of them by the name of one of them is a mistake. Especially since it seems that some are pushing the notion that HTML shouldn't have a version number to begin with.
