Since no one has successfully made a robot worthy of an Asimov story, I would say that no one knows what is easy vs hard when it comes to robotics. We can make guesses but in the end until someone has a working copy, we won't know which parts of the development process were the most painful.

You can get a prepaid phone. Without a monthly contract a phone really only costs as much as you use it.

If you're only using your phone for job calls, this should be fairly cheap.
the point was that putting any $computationally_expensive_fn in your event loop was a terrible idea.
in this case he then did
$computationally_expensive_fn = fib;

the point is, unless this event loop pretty much does nothing or hands off the work to a pool and returns immediately, it is utterly unscalable and needs a multiplexer to sit infront of it.

most servers do

while(1) {
$conn = accept_conn();
new EventThread($conn);
}

Thus it's simply multiplexed. Alternately most current other web languages take the approach of integrating with apache which does this one level [up/down?] and they don't have to worry about it at all.

The point is you can write safer code in other languages even if it is slower by it self. With node.js you can do some really dangerous things if you go it alone. You must deploy node with something else, but that's kind of an after thought left up to the dev, and loads won't because they are all under the mistaken impression that because node.js is faster than php/python etc that alone solves all problems and excuses them from sane scalable coding practices. At best it just puts it off a little further down the road. And anything built into a webserver doesn't have to worry, while node will.

No:

The round of new charges stems from a rule, which takes effect on Saturday, that limits the fees that banks can levy on merchants every time a consumer uses a debit card to make a purchase.

Given the low rate of fraud on debit card purchases, banks were previously making a killing on from debit card fees; with those fees reduced, they need to find an alternative revenue stream. US banks aren't exactly doing well these days, so their need to replace that revenue with something else is understandable.

Heck, I took a big pay cut to be happier. I was a .NET enterprise developer in the six figures.

There is something about building things outside the box instead of being part of an assembly line at corporate shops. The lack of politics and endless meetings is a bonus too. It's not always about the money.

I'd blame the implementation, not the platform in this case though, seeing how others have linked much faster JS raycasters.

Developers using many major frameworks/languages don't need to quote a single or even a set of "gods" of the framework/language to back up their point. This is one of the problems in Rails, imo. Everything is still about following celebrities like sheep. That is a bad road, my friend. I would much rather live in the midst of a thriving city or within a growing town that had promise than within a hippie cult commune (regardless of its size or the quality of its food or company). Think for yourself. What would you like to use, and why?
Lucky you! Between PGs essays and HN, you have such a massive competitive advantage over your local peers. :-)
A long time before ruby or python gained popularity, there was perl. Perl does not have a GIL.
I don't think we disagree about the fundamentals, but there are trade-offs there too. C extensions become harder to write for example. This is fine for something like the JVM where people stay in JVMland for the vast majority of things.

I don't see why people are so insistent that other languages need to go down this route. Use one that does if you really want that stuff. Hell, use ruby then you can switch between C ruby and JRuby depending on your needs.
What's really odd is that the folks who talk the most about the problems for lower-class American workers will get most offended the moment you suggest that competition for cheap labour from millions of illegal immigrants might have something to do with it.

It's not the Lump of Labor fallacy to say that the economy has a limited appetite for low-skilled workers. In Australia, where illegal immigration is quite limited, it's not a choice of Wal-Mart and the gas station for folks without white-collar skills, there's also farming jobs, cleaning jobs, and best of all, tradesman jobs like builder, electrician or plumber. You'll need an apprenticeship for some of those, but can quickly work your way up from earning very little as an apprentice to earning six figures as a competent and fully-qualified tradesman. But in America, all the job categories which I mentioned are dominated by illegals, so it really is true that the uneducated have a really rough time.
If you've been following this argument from the beginning (I'm very sorry to say that I have), you'll notice that Ted's point is not that you WILL do CPU bound tasks in Node, but that Ryan Dahl's misleading statements on Node.js's front page is absurd. Of course no one with any sense will put CPU bound jobs on the same process/thread/event queue as the one processing the request. But you do have to realize, it is exactly that no one will ever do the above that renders Node's existence rather pointless. Threads/processes or events, you'll still pass off the heavily computational stuff to a different processing queue. Events or threads, when that single process starts topping out, you'll still have to launch another process. What makes Node.js different from any other technology that have come before? Nothing except that it comes with a server and it's written in JS. If you like the Node REPL and JS, that's fine, just don't propagate the urban myth that's on Node's front page. I think this is Ted's point IMHO.
Another boring, silly "jumping the shark" post
I worked in .Net shops for a few years, back in the days before .Net MVC. Part of the reason people ended up (and maybe still end up) stuck in .Net might be because back then, as soon as you tried stepping outside of the .Net webforms box (i.e. tried to do anything remotely interesting) things because exponentially complex. Keeping all of the .Net classes and foibles in my brain during my day job was enough for me not to want to learn the intricacies of a different system in my off time.

That was years ago though... and since then I've happily moved on to being self-employed and using OSS.

I didn't mean to nitpick your post specifically. It was more of a comment on the attitude of many entrepreneurs. I really liked the your perspective and the idea of self-directed work in general.

I'm more frustrated with the idea that we're encouraging everyone with talent to be permanent generalists flitting from one idea to another, never getting a deep understanding of one organization or specialty. The "find smart people and figure it out" approach is great if your ambition is medium-sized, but you can't build the next amazon without eventually needing longevity and specialization.
I'm annoyed at this, but I probably won't switch. I rarely use my debit card to make purchases, since I have a BoA credit card with reward points - and I've heard that debit card fraud is more difficult to combat.

Do most people shop with their debit card?
I thought the point of stacking the deck was to show that broken homes and a failure to save are root causes of poverty, and not readily-reversible ones. That said, people generally don't choose to lose their adequately-paid job and spouse any more than they choose to be the target of a Cultural Revolution lynch mob; certain behaviours increase the chances of it happening but bad things happen to people who make good, or at least explicable, choices too.

Sure, China had terrible problems with revolutionaries, before reforms leading to a remarkable rate of economic growth that nevertheless still leaves the average person in living conditions that would appal the average debt-ridden member of the American underclass. Mostly they "pulled themselves up by their own bootstraps" by being able to work for (or employ people on) the sort of wages that would leave Americans unable to eat, never mind have houses, cars and mobile phone contracts to owe repayments on. So they didn't do it in isolation[] and their model doesn't work for the US unemployed. Perspective is useful, but deeming freedom of choice and support for the poor in a rich democracy to be adequate by comparison with a poor country rapidly recovering from internal chaos is like judging the adequacy of a government by how many gulags they operate. By the standards of first world countries, the poor in the US get a relatively rough deal.

Singapore, since you cite it as an example, is a million miles away from a society where people pulled themselves up by their bootstraps from capitalism. For a start, the government cleared the slums by building 85% of the country's housing stock and fixed the rents and prices far below private-sector levels. They might be extremely business-friendly, but governments in democratic states don't get much more paternalistic than Singapore's.

[]Arguably the American poor have benefited far more from the resulting availability of cheap consumer goods than they lose from cheap Chinese labour pulling down on the bootstraps of the US manufacturing industry. But the availability of those jobs is still reduced.
How is this different from Mint (that is free and syncs with all the accounts)?
Combining two incomplete proteins (rice, beans) to get a complete one. As opposed to eating generally more expensive complete proteins (meat, dairy).

This saves money, but it's actually pretty small compared to other ways to be more frugal. So I probably shouldn't have brought it up.
The whole target of his dissatisfaction is this quote on the Node home page: "Almost no function in Node directly performs I/O, so the process never blocks. Because nothing blocks, less-than-expert programmers are able to develop fast systems." That's bullshit. Evented programming isn't some magical fairy dust. If your request handler takes 500ms to run, you're not going to somehow serve more than two requests per second, node or no node. It's blocked on your request handling.

And all that stuff Apache does for you? Well, you get to have fun setting that up in front of the nodejs server. Your sysadmin will love you.

Basically if you're doing a lot of file/network IO that would normally block, node is great. You can do stuff while it's blocked, and callbacks are easier to pick up and handle than threads. But how often does that happen? Personally my Rails app spends about 10% of its time in the DB and the rest slowly generating views (and running GC, yay). AKA CPU-bound work. AKA stuff Node is just as slow at handling, with a silly deployment process to boot.
Yes, this is something people legitimately want. There are lots of occasions where I will go somewhere with friends/spouse and want to wander but occasionally sync up or know where someone else is. It sure beats SMSing "where R U" messages back and forth.

What surprises me about this is the reaction to the leak.

If the leak were about Apple, there's a vocal group that would be defending the leakers as doing the right thing, like they did something moral, and decrying Apple's efforts to keep things secret.

With Google, again there seems to be some sense of entitlement to internal Google emails, products and decisions, although the detractors aren't quite as fervent as they are in Google's case.

But Amazon? For some reason everyone seems to be all over whoever leaked this screenshot of an internal tool.

Why the double standard?

As for the numbers themselves, they look positive but not mind-blowing. This probably translates to selling 1M+ at launch, which is a good, solid start. I own an iPad 2 and am tempted to get one of these anyway, just as an impulse buy.
Well, but everyone's read "The Story of Mel" :)
In my experience, looking at it from the other side is even worse. In fact, it's so bad that as soon as they hear Microsoft their brain shuts down. They get this emotional reaction that makes any rational discussion difficult if not impossible.
I guess I edited my posting while your were answering, sorry about that.

I clarified that I am actually more worried about the public reaction to this rather than legitimate use cases. Not really worried, just, why not leave it at a third party app?

To answer my own question, Apple's solution has probably both more polish and more lock-in power, just as with iMessage vs WhatsApp & Co.

Bulldonkey. Javascript on client side will continue for the foreseeable future which means those developers would want to use the same language to do server-side. Just because it hasn't taken hold, doesn't mean it won't.
Someone looking to hire a secretary to temp for a week to cover a vacation cares that the temp will be productive. This means that that secretary can teach the temp what they need to do for the week, and the temp will be able to do it quickly and efficiently using the templates and tools that the office uses. If they keep track of accounts in excel, you need to be able to quickly enter data into excel to use their system. They're not going to switch to something better just so they can employ you for a week.

This doesn't mean you're unemployable outside of software, just that this heuristic suggets you are a poor candidate for a temporary secretarial position.

Sure, just like a lion's need to eat zebras is understandable. But the zebra is still going to be pissed, and will probably switch to another bank or credit union.
21% were looking for .NET developers with 8-10 years experience.

Wikipedia tells me that .NET 1.0 was released in February 2002, 8.5 years ago. Good to see recruitment companies and HR depts have such realistic requirements. (Still, at least they aren't asking for anyone with 10+ years experience)
> And those solutions certainly don't preclude the "think" option, they augment it (Also, I've already RTFM).

Most people don't do these steps at all anymore.
I have to agree. But I still think it's weird that we're giving up Flash, with the argument basically that 3D games aren't necessary in the browser, and then going back to the stone age to reproduce basic 1993-era functionality in Javascript of all things.
I've never had trouble (so far at least) with HN, but I frequently need to switch to my filter-avoidance proxy for various HN links. Ironically, I am using proxy-avoidance software to get around a "blocked - category: proxy avoidance" message.
You seem to be saying that "the best technical people", because they are so good technically, are, then, necessarily less good than others at "business/social skills".

It's an old myth used by people without technical expertise to put down technical people. The put down is quite general with a cute twist: The technical expert is painted as good ONLY at the technical topics and is poor at EVERYTHING else including even ordering lunch. It's just a put down to win in competition within the organization. The usual way to avoid such a put down is to 'fit in', 'go along', and 'don't stand out'.

BELIEVE me, becoming a technical expert does not somehow ruin a brain for other work.

It is true that some technical experts don't bother with 'social', etc., but the issue is desire and not ability.
I got one, and the only thing I'm worried about is that the touchscreen might be lame like the Nook Color's: http://www.youtube.com/watch?v=LiHH6mdH0WU

I guess this philosophy is why so many "web 2.0" companies make terrible iPhone apps. If testing and QA is responding to users experiencing bugs, then you will fail at making good packaged software.
In Canada we do.

I think the reliance on credit cards is largely an American phenomenon.
So Jobs is idea/credit snatcher Edison, and Tesla owns them all. I can agree with this.

The one things Jobs has done that no one has is changed how the masses use technology in such a short period of time. I don't think many fall into that category.
I did for the first five or so years after I moved to the US. At first they wouldn't let me have one because they had no way of checking my existing credit history, and after that I mostly continued out of spite. Eventually I gave in and got one for the cashback, though.

Whoa, whoa. "Just as slow at handling?" It's most likely an order of magnitude faster at handling those.

But you're right, deployment isn't a totally solved problem. Unless you just use Heroku: http://devcenter.heroku.com/articles/node-js

I mean, Node was created in 2009. I don't see anybody bragging about how easy it is to deploy yet; just that it's fast and easy to understand.
scarmig, not that I disbelieve you, but can you provide citations to help me understand when and how often this occurs?

Labor regulation is massively skewed toward the employer compared to any other developed country.

I'm not interested in comparisons to other countries. My interest is in both sides playing on a level field. When, for example, the government is trying to prosecute Boeing for simply deciding to open a new plant in a non-union state so that it won't have to deal with the union [1], it's clear that the playing field is slanted. I'm not asking for businesses to have an upper hand, just that the situation be handled with as much fairness as possible.

labor consultants known affectionately as "union busters" who spend their time and efforts intimidating employees.

I've never encountered such a thing. My understanding is that this kind of thing disappeared decades ago (although these days I don't tend to work near unionized people, so may have missed something). But: how can you explain the insistence on the particulars of "card check", other than that the unions want to be able to intimidate workers into signing up (which they'd be able to do, since their votes wouldn't be secret)?

Disclosure(s): I've had my parents tell me that we won't have very much to eat for a while, because my step-father is being forced to go out on a strike that he voted against. I've been forced to pay union dues myself, even though (as a temporary employee) I wasn't entitled to union benefits or representation. I've been forbidden from helping customers by a simple 1-minute effort, because only union workers are allowed to do that task (although the union workers were not doing their duty by performing that task). My employer had union protesters [2] fake a picketer being hit by a bus, those picketers claiming that justified their attacking the bus with bats and pipes.

[1] http://www.bloomberg.com/news/2011-04-20/boeing-should-move-...

[2] The protest was simply that one of the building contractors my employer was using for a renovation was not a union shop; there was no concrete grievance. And the bus that was attacked was carrying the non-union workers to keep them safe from the union animals.
This is about how many iPads Apple sells, just at a much lower price point. I imagine these numbers are going to grow rapidly once people actually see the hardware. The market isn't even close to tapped.

This seems to sum up the article (and your response) pretty well:

"Why the shortage? ....NET developers earn around $83,000 per year, but Java developers typically make more than $91,000."
Not true. Most of them go on regional or national tours several times a year, so if they have a job on the side it must be very lenient.

Another thing to consider is the basic IQ requirements of modern high quality jobs. You don't need to be a genius to be a Doctor or Programmer but good luck finding them with subs 80 IQ's (~16% of the population). It may have been more dangerous and paid less to build the Model T but it was also reasonable to send just about anyone to that type of work. Now add to that Illegal immigration which results in fairly intelligent people doing manual labor for low pay it's even harder for people that are a little slow to compete.

Slower than what?

The great thing about HN, and similar discussion systems you'll find on the internet, is that you can read the conversation. So when I say "slower", and reference "antrix", a sentient (or even a reasonable AI) could infer that I was referring to this statement, by antrix:

>If I replace my memcache logic with an in-memory thread-safe hashmap, it will always be faster. I can't see how it can be slow.

And that you replied to by quoting it.

Clearly, by reading the english therein, antrix is comparing the memcache logic with a thread-safe hashmap. So in case you still aren't getting it, the answer to your question "Slower than what?" is "than a thread-safe hashmap". That you are not aware that this was antrix's assertion would explain why your subsequent posts fail to refute it.

So your behavior is not merely that of a response factory, but a response factory with a 1 deep context buffer.
