I spent my last three years doing various roles at two e-commerces in Indonesia, both top 5 in terms of traffic and transaction. For my last two years, I am doing backend works, both implementing features, system design, tuning performance (both from apps and infrastructure perspective), and doing developer tools.

I'd be very interested in working at either developer tools or high performance/scale processing.

Feel free to contact me if it looks like my skills fill your need. Good luck in your search!

I've been reading the "How to pay for this book" page [1] and noticed that there the author said:

> I pro­grammed a new web-pub­lish­ing sys­tem.

I seem can't find any other reference to that, and still not sure about emailing the author directly yet. My google-fu failed me on this one. Anyone know if the author's system has been published or sold?

Thanks before.

I found out about this book because the author's tweet (saying he wrote it in Racket) was retweeted by @racketlang https://twitter.com/mbutterick/status/359768757733826560

Thanks! Much appriciated!

So no, it doesn't seem to be published.

It will be long before someone implement this in the real world (website). It needs 16MBs download for the standard libs. Even twitter only downloads around ~2MBs before showing page.

Yeah, and I'm not sure scala will be that useful without the standard libs, much like C# or Java.

Seeing the presentation, I'm thinking more of using it with something like node-webkit[1] though. Didn't LightTable use clojure-script or something? But then, why don't just use one of JVM's GUI framework?

I'm doing something for fun with Clojurescript and node-webkit and for me it's mostly that I want the fast start up time, but also to get to just work with html instead of having to learn a gui framework.

Also I just want to mention that Clojurescript compiles to javascript that's compatible with Google's Closure compiler, which can do dead code elimination and will remove the parts of the standard library that you don't use.

    Long before the Facebook age, 
    I noticed something very interesting about 
    the personalities of the most vocal people
    I would meet in chatrooms, instant messengers 
    and bulletin boards: They were mostly shy. 
    It took a while for me to realize that this should 
    have been expected. Shy people tend to prefer the 
    anonymity of the internet, where social cues from 
    body language, eye contact and tone of voice don't 
    apply—largely because they are invisible to all.

This hits right at home. When I'm active a lot on facebook / twitter, I am a typical shy guy with little social skills. Then I started going out a lot and meeting lots of people. Then boom. Less twitter and facebook.

This might applies to HN too, but sometimes I find it weird because some people on HN are successful, and I think you can't be successfull without good social skills. Maybe we grow to become good socially, but still attached to the community? I've never experienced that though.

wait, the article is not sarcasm? I thought the site is some kind of the Onion for programmers?

The main sarcasm is people missing the point, while it's there, in the first BLOODY line of the article.

It's in a box which has the effect of making it invisible.

Doesn't look like one.

"Andy ‘Wise Owl’ Brown decided to write a tongue-in-cheek rant".

First line in the article.

> Few jobs are now so arduous that 70 year olds cannot perform well.

I think it's mostly physical jobs that 70 year olds cannot perform well. And that kind of job can be automated by robots anyway. For job like programming or CEO, I kind of think that 70 year olds can do better than say 20 year olds.

Mental acuity is very much a physical quality. Yes, there are 70 year olds who can think and mentally adapt exceptionally well, just as there are 70 year olds who can do one arm push-ups and live till 100. But it doesn't mean that 70 year old are just like 30 year olds, but with more experience.

Most of the studies that showed rapid mental decline in old age have been debunked. A 70 year old with no actual problems (e.g., Alzheimer's) is very likely to function perfectly fine mentally.

A 2002 study (published in the Alzheimer's and Dementia Journal) found that ~91% of people 70 and older were capable of normal mental function.

Seriously? How many 70 year old people do you know? Let say you need to urgently take your child to a doctor and can choose between a 30 yo and a 70 yo. What would you do?

Parent cited an experiment that found 70 year-olds to have mental functioning on par with young people. Would you like to argue against the study's conclusion in a meaningful way? Or are you just pointing out that regardless of what is true, humans tend to act in a biased and ineffective manner?

That's a straw man right there. Why would it matter? In terms of the decision making, the one with more knowledge is better. In terms of driving, it depends on if the 70 year old still has the PHYSICAL ability and acuity to drive a car, which is exactly what we weren't talking about.

I'd say the 70 yo doctor is less likely to prescribe new 'fad meds' that cost more and perform worse than the classical drugs

Also, experience

If you look at a site/product like Lumosity.com, you can compare your results to other age groups. If you accept that the tests on Lumosity do test particular brain functions/areas then its clear to see that from the millions of user that take part, the performance average does decline with age. It's actually quite dramatic to see that a 40 year old that scores in the 90% in a test category, fits in at 50% among the 20 year olds.

You can't really get any meaningful results from a self selected sample.

Since there is no other evidence that a 40 year old in the 90th percentile for mental performance is equal to a 20 year old in the 50th percentile, it seems more than likely that the data is skewed.

Perhaps Lumosity.com attracts above average young people and below average older people (given those results, some variation on that theme is the likely explanation).

For what it's worth, top chess players decline in skill with age, so it matters for at least one mental activity.

An otherwise almost imperceptible decline in mental function could have have a huge impact on ranking among top chess players simply because at the top levels the margins between players are so small.

If chess Grandmasters dropped in mental acuity as fast as those Luminosity results suggested, a 60 year old Grandmaster could be beaten by any young novice.

Also worth mentioning is that competitive chess is favors very quick thinking and action in a way that most careers don't.

>>For job like programming or CEO, I kind of think that 70 year olds can do better than say 20 year olds.

Maybe in 50 years, but currently I'd say a 20-30 years old is the prime programmer age. Young people tend to learn new tech quicker, and be faster/more efficient at typing and using computers.

Are you so sure about that? I'm 53, and I believe I'm a far more effective programmer than I was in my 20's.

A 53 year old who has been programming for 30+ years is likely to be a good programmer because they managed to keep programming for all those years. How many of the less-talented people you started out with are still programming?

But I do agree that it without hard evidence, it's unfair to assume older programmers are slower or less capable. I have personally worked with some exceptional older programmers.

...typing and using computers? So you're comparing 20-30 year old programmers with 40 year old people who aren't even comfortable with computers? Yeah, I'd say apples are way better than oranges.

This is interesting. I live in Indonesia, where except on our capital (Jakarta and most Java), working 60 hours a week is the norm. I have noticed (and I think this has been proved over and over again) that people who works 60 hours a week is actually less productive and less happy than those who have a free weekends and work only 8 hours a day.

I wonder how much working time can we cut until the benefits disappear.

I agree with this from personal experience. And I have a US white collar job, 70/hr week average, and i'm way less productive than I used to be before that.

>>>working 60 hours a week is the norm

What kind of labor is that? White collar or factory assembly?

do you have extremely long days but 5 days a week or do you spread it out over 6 or 7 days?

In Japan, by the way, it is not uncommon to work 6 days a week (Saturdays). It depends on your contract.

I heard a story, perhaps apocryphal, that the national government commissioned a study a few years back to investigate ways to curb this practice.

The committee was disbanded after a minor scandal when it was discovered that they were making everyone come in on Saturdays to work.

> I actively develop for Android as well, and I can say that BlackBerry development has done so many things right. It is really a dream to develop apps for. As a user, it's fantastic too.

I haven't seen and tried BB's SDK, but could you elaboreate more? Didn't they still use Java ME (which sucks compared to Android's IMO)?

BB10 is nothing like the older platforms, which kinda sucked. You couldn't even run code on a test device without getting it signed by RIM, and the service crashed frequently.
