Nope. In the F# version, the '+' is passed in as an argument. That is harder to do in c# without wrapping the operator in a function.

it's probably more like

applyBinaryOp(op, a, b) => op(a, b)).

Where op is a wrapper function, in the case of '+' it would be

Func<int, int, int> op = (a, b) => a + b;
I hope MS will up there release schedule just like Apple and Ubuntu. When OSX first landed most people didn't like it at all. But every year it was a bit better and at least since 10.4 one of the best if not the best desktop OS. Same thing go's for Ubuntu, the first incarnation of Unity was not good . But 12.04 is a really usable OS and for me (since I don't use OSX specific software) perfectly fine replacement for OSX. I'm really excited to see where they are going with it. So if MS is serious about there new desktop they should release a new version at least once a year. Perhaps they will need a LTS strategy for the Enterprise starting with windows 7. So by the time windows 8.4 comes a long Metro is matured and most workers will know how to use is.
I recently did some testing of PHP 5.4 and found pretty much the same thing. Its faster but not _that_ much faster.creating and serializing a huge object to YAML still take about the same time. The only thing I have found is that I get a little bit better performance out of mod_php, and memory usage is down about 20%

What separates Rothko and Pollock from the artists in the link is that other people have tried to capture what they captured, and failed. I never got it until I finally saw other rectangle blobs and other paint drippings. There is at least something there to be felt.

Indeed, I didn't mean to suggest realism is no longer an interesting art form. It is certainly well established, and perhaps this is a testament to the fact it has plenty to offer. I was simply attempting to bring across that many artists are more interested in less familiar uncharted territory in which to push the boundaries of new exciting ideas.

> I can't imagine how typing the name of the app you want to open is a design failure.

It's nice to have, but something is wrong if that's the fastest way to start a program. Even if you're a fast typer (most people are not btw), it's way to slow to use with commonly used applications.

My favorite ways to launch the apps I use all the time are:

- Keyboard shortcuts! Seriously, try it :) available on most linux/unix gui's.

- The launcher in Mac OS X, or "pin" in Win7: After logging in to my windows desktop I often start 3-5 programs in 3-5 clicks. Would be a pain to have to type the name of them all one-by-one >(

- Customized menus. Works ok, but still find it slower than the others. Never use the menus in fluxbox, I just use keyboard shortcuts for the common ones, or a terminal for the others (almost as fast as typing the name in gnome3)

- Typing the name. Use it on gnome 3 and kde sometimes. Mostely becuase I haven't bothered to set up keyboard shortcuts.
Yes, but I did make use of strong emotional story-like elements to make my point.
Yes, all information models are basically isomorphic. However, Neo4j for instance maintains referential integrity along the relationships, making sure there will never be a relationships without start- or endnode. In a K/V store or document store, there are no guarantees that your IDs pointing to other objects are updated as you change, delete or move the target data. Also, the graph structure is maintained on dics, meaning you can direct pointers on the storage level even in non-cached scenarios, while in a K/V or Document store you need to recreate the graph in memory before being able to do anything with it.

As for special indexes and queries, look at things like http://docs.neo4j.org/chunked/snapshot/cypher-query-lang.htm... expressing patterns and walks in graphs.

You can combine index lookups in e.g. Redis, MongoDB or Lucene with the core graph engine.

See http://docs.neo4j.org/chunked/snapshot/index.html for docs.

iOS devices do not support OpenVPN nor OpenSSH. You can use L2TP, PPTP or IPSec for VPNs.

So, I can either pay for tunnelr.com and have zero VPN support on my iOS devices, pay for two separate services, or switch to a provider that supports both. I suggested that while it's fine to tell people not to use PPTP, some of us will still want to use it, because it is better than nothing at all (please don't make me argue that it really is better than no VPN at all).

Here's a statement of fact: at present, the only reason tunnelr.com does not get my money is because it does not support PPTP alongside OpenVPN.
"But in the presence of statistical evidence, don’t tolerate contrarian anecdotes, and don’t make them yourself, knowing the exaggerated impact they can have."

When you start to design a statistical experiment, you have already made an important methodological choice. See

http://en.wikipedia.org/wiki/Positivism

http://en.wikipedia.org/wiki/Grounded_Theory

I've noticed that in my own field which is education, there appears to be a fondness for sophisticated statistics, even though no manager ever allocated students to teachers on a double blind random basis. An excellent example is the way the UK Education ministry has decided that 'phonics' is the way to teach reading.

http://www.bbc.co.uk/news/education-18462214

I think that this general tendency might be an example the 'white coat syndrome' in action; belief that using formal statistical techniques might increase the meaningfulness of the results. I suppose that is a form of cargo cult.

This is hacker news, a forum aimed at people with novel business proposals and new software to try out. Should you be trying to find 'the Truth' or should you be building some grounded theory that tells you what to do next, provisionally, now, today?

> Normally we fear expanding a home server because resizing a RAID always means copying terabytes of data off somewhere else, wiping the lot and constructing a new one including the original disks.

This is just wrong. Only last week I resized my RAID5 array from 2 drives (basically RAID1) to 4 drives. Reshaping and resizing the ext4 partition was all done online with minimal performance impact. The only bit that took a long time was the reshaping, and even then it managed to add a new 2TB drive in only a few hours.

Even upgrading the entire array to use a larger size of disk is pretty easy. You do need all the disks to be the same size though :(

There might be some optimizations on top of that, but overloadable operators in C# do get compiled to a function call (a static method call, if you want to be pedantic): http://stackoverflow.com/questions/6587107/c-sharp-operator-...

See VMAtm's comment's bytecode, showing that "[Decimal] + [Decimal]" compiles to:

IL_0011: call valuetype [mscorlib]System.Decimal [mscorlib]System.Decimal::op_Addition(valuetype [mscorlib]System.Decimal,
valuetype [mscorlib]System.Decimal)

Non-overloadable operators (short-circuiting operators (|| and &&), ternaries and its ilk, field access and (of course) the assignment operator) are probably compiled straight to bytecode, but they're pretty special and (especially in a strict language) need special runtime support anyway[0].

To sum up: mquander is completely right, the CLR does not know anything about operators, language compilers will take whatever operator they have at a high level and compile them to method calls (usually). For more details, see http://www.amazon.com/dp/0735627045/

[0] other runtimes make different choices, Python encodes most of its operators into bytecode for instance: http://docs.python.org/library/dis.html#opcode-BINARY_POWER

Art is just communication.

The thing that sets art apart from mundane examples of communication (such as perhaps instructions for a tax form) is that art typically is evocative of emotions and feelings. Or perhaps complex thoughts that must be arrived at indirectly.

Art is really no more complicated than that. But there is so many different ways to achieve communication through different forms. Sometimes people are prone to over-simplify art, or to try to make art objective, or to try to make a firm boundary between "high art" and mundane art, but none of that is possible. Art is inter-personal, and can mean different things to different people. Guernica, for example, could have a different impact depending on ones personal exposure to warfare and violence. And that of course means that trying to put in place objective standards about subjective communication is fool-hardy at best, as is trying to create some sort of ranking.

You don't have to like all art and it's fine if not everyone likes the art you like.

It's fascinating to me that the same applies to cuisine and we accept it just fine. Some people like sushi, some people don't, some people like steak, some people are vegetarians. Art is the same way. Liking some types of art may make you appear more sophisticated in some circles (such as liking red wine and salmon vs twinkies and big macs) but in the end it's all just personal preference.
I understand your intent, but it reminds me a little of Ford's "... any colour so long as it is black" remark. The kudos button only caters to a single form of opinion, and at that it's a little vague. I appreciate the effort at simplifying the gauge of sentiment, that should be continued, however I'm weary of loosing out on the nuances of personal interaction. This discussion we're having here is a good example of that.

I think the Kudos button is an interesting idea, but I'm not sure it's the right one. Something a little more malleable, something that facilitates a broader spectrum of opinion while maintaining simplicity would be better, I feel.

I don't think anyone here will claim that art is about realism. And I think "indulging in a perceptual experience" is an absolutely brilliant definition of art.

The problem is that a lot of modern art, which includes some of the pieces in TFA, fails that definition as well because it relies too much on insider context. Art that is designed to be "understood" in a way that requires a 5-page explanation to someone not familiar with ideas and trends known only to people in the modern art industry is not a "perceptual experience", it's a riddle game with a very limited target audience.

Truly great art may have such aspects as well, but they take a backseat of the "perceptual experience" aspect, which makes it recognizable as art to almost everyone, even of they don't understand everything the artist did.

A few years back I was visiting MNCARS (Madrid) with a friend of mine who had no understanding of art whatsoever. He didn’t like my decision to visit the museum and I could tell he felt a bit uncomfortable. So I told him we should try something of an experiment. We would choose a painting, stare it for a while and then exchange opinions. And that was what we did, we chose a large painting and after watching it for a couple of minutes I asked him how he felt about it. “It makes me feel unease” he told me. “I don’t know why but it makes me sad, frustrated, in despair. I just want to take my eyes away”.

The painting was Picasso’s Guernica . Years after my friend told me that this single event had a significant impact on his life.

So my opinion is that if art needs explaining then it’s not art.

in C# you can't use operator sections so you'd have to wrap the operator in a lambda explicitly:

How To Silence A Computer

I wonder if Microsoft's numbers (which we're assuming they have and use) aren't skewed by the usage patterns that they create, with users taking the path of least resistance for the given options, which are themselves sometimes paths of a-fair-amount-of resistance.

For instance, I frequently switch windows in Win7 with Alt+Tab, but also dip into the task bar quite often to click the Word icon, then identify the correct Word document open, then move the mouse to the document... neither of which are particularly efficient.

The only approximate solution I can think of would be having a touchscreen above my F-keys to select apps with. I can imagine MS have no data on how well that would work.
Yeah it is horrible at knowing what you are more likely to want. Doesn't even require that much thought, just put applications first.

I believe modern art (which I am not into) suffers from an anti-intellectual approach anytime the subject pops-up in my circle of technical friends.

On the other hand I went to an art school for a year and met a lot of incredibly elitist wanna be into Klein and the like that would never show up in history of arts class where they could have learned why some weird paintings were important stepstones in art (but they were capable of admiring the piece for two hours in the museum, go figure).

One of the biggest problems Java faces for real adoption amongst tech people is still the perception (and I am not sure it is entirely flawed either) that it is insecure.
