They talk in this article about the complexity of Scala. Odersky typically combats that accusation by saying that Scala's not so complicated. He did that in this article, and I've seen him and others do the same in other places.

But the fact is, it's pretty damn complicated. At least it was, to me, but I realize now that's just because I didn't grok functional programming in the slightest. Scala seriously turned me off at first, and I found it very hard to learn. There's a lot of little tricks it does, and special rules. Like how there are many different ways do progressively shorten inline function definitions. For example: you can either say: "args.foreach(arg => println(arg))", or you can say "args.foreach((arg:String) => println(arg))", or you can just say "args.foreach(println)". And the books I have explain that in kind of a complicated way that explains partial functions way sooner than I was ready to understand. All those different options of ways to do things made me have a hard time understanding what the "right" way to do things was. Similarly, the ability to do ultra-shortcuts on inline function definitions really confused me at first, for example being able to say map(_ + _) instead of (a,b => a + b).

For loops were also kind of bizarre to me. I remember thinking, "Jeez, would it kill you to just let me write a frickin loop for goodness sake?"

I perceived all this as excessive trickery and complexity in the language, and decided to bite the bullet and learn Erlang, instead. Erlang is a far, far easier language to learn. It was a breeze, actually, once I relaxed and forced myself to embrace it instead of hate it. (I failed to do so on a previous attempt to learn it.) In the process, something amazing happened: I started wishing that I had access to a lot of those things that I initially hated so much about Scala. I started wishing that I could write map(_ + _) instead of writing map(fun(A,B) => A + B end, L) like Erlang was forcing me to do.

Point is, if you're finding Scala off-putting or overly complex, like I did, then consider taking the time to learn functional programming with Erlang. You may even decide you like Erlang better. Erlang is better for some kinds of applications and situations. But for me, I found it way easier to learn Erlang first. Because until I was forced to do pure functional programming, I didn't appreciate the value of it. It prepared me to really appreciate Scala.

You're wrong in many ways.

1) They have principles. I know the GC personally and he is a very principled guy. So are ev and biz.

2) Having principles isn't counter to the ability to recognize gains. In fact, the idealist in me hopes and has seen how they are intimately connected.

Also, remember that if you start giving into every request like this without a fight, they'll end up looking like a patsy. They fight and they know that they'll be taken seriously by law enforcement and by their users. I'm glad twitter did this.
I've met people that were raised like that and they're broken.

They lack the volition to do things by themselves and are unable to make their own choices. I used to converse a lot with a girl brought up in this manner and if you asked the question: "why" a lot about the things she did or was about to do (like planning to go to a particular college) you would ultimately end up with: "I don't know".

Also I would bet that those kids are bullied to at least some extent at school. They would have been at mine at least. :D

Where to get a list of US company names?
I am working on a web application that needs a list of US company names. Any suggestion on where to get it? There are couple websites that sell the names for couple hundred dollars. Not sure if they are legit. Thanks.
For me it's fine to think they did it out of pure greed (i.e. they realize they are direct competitors to news companies so if they show themselves to bow to this pressure no one will use them for anything controversial again). That way they're more likely to keep doing it in the future, even under new management.
Twitter's still small enough that they can make decisions out of principle, without them being diluted by a corporate structure. This strikes me as something Google might have done a few years ago.

I was raised like this as well and surrounded by Asian parents who do this. I see a few of my Asian peers, as young parents, exercising the totalitarian technique as well.

I supposed, in the end, my dad did it. I accomplished all his goals at relatively young age. But that comes with a huge cost. I never see him as a loving caring dad. He is always the target to beat. Sucks to be him now, old and alone.

This article and other Asians who follow Amy Chua's style of parenting rarely see this one perspective:

The oppressive technique is cargo-culted to death among Asian parents. It is used by Asian parents who themselves, are not successful like some sort of miracle drugs.

This technique only works IF the parents themselves are successful. If the parents are lazy, glutton, and messy, there is no way this technique will make the kids dapper and discipline.

For those of you who suffer/ed Asian parents oppression, there's always the satirical: http://highexpectationsasianfather.tumblr.com
This is basically what is called "tethering", using the 3G internet connection of the phone for other devices (such as your laptop), except that the "tether" is no a physical connection but just a wifi connection. In other words, you put your phone into this mode and you can connect to it through wifi and have wireless internet anywhere you have 3G coverage. AT&T does not offer the same service.
Agreed. It's all relative.

You get the whole Java ecosystem at your fingers.
It's faster than MRI (1.8.7ish) and a contender (maybe even faster now) against MRI 1.9.2.
It interops with other JVM languages.
It plays nicely with uptight IT departments (you only need to download the jars).
I am currently evaluating alternatives for a new architecture at my company. Clojure on the JVM is on my list, but I'm really nervous about Oracle. I realize the community can fork the VM (or just move down the Harmony road), but I don't want to get caught in the middle of the battle.

Every time Oracle does something like this, it pushes further away from selecting it. Guess I need to brush up on my Erlang.
It's a limitation to CDMA, so if the same feature were allowed by AT&T you wouldn't have a service interruption due to voice usage (GSM can do voice and data simultaneously).
I'm not including him in that group; I'm not convinced that he left for financial reasons.
Types and the Web
Verizon iPhone can't handle data and voice simultaneously
I mentioned this above, but I'll expand on it here:

What does Twitter have to offer, really? Do we really care about Paris offering links to her friend's vagina? I mean, that, "Shit my dad says" and so on are entertaining and maybe worth a little bit but Twitter's real value is as a news service. If you're following the right place you can get instant news in a way not possible almost anywhere else. Would we have even heard about the Iran riots without Twitter? If they're going to be the place for scoops for the world they can't show themselves as someone who will give you up the first time the US asks.
If people wanted an iPhone, they could have just gone to AT&T and bought an iPhone. While this will probably reduce sales of Android phones through Verizon, I certainly don't think it means it is 'all over'. I agree prices may drop on Android phones, and manufacturers may have to step up their game a bit more especially in terms of software.

With Android phones you have a choice of prices, different hardware configurations including physical keyboards, easily replacable batteries, expandable memories (i.e. buy a 32GB card for $50 vs. paying Apple an extra $100) and not least, the freedom to run whatever software you choose. While some nice things like game emulators are available for Android, though, it's true that iOS has a wider range of software for now. Another issues is that many people are turned off by the Apple brand, for one reason or another.

HTC, Samsung and Motorola have some impressive offerings of their own, hardware wise, and I'm sure they'll continue to sell plenty of phones.
The theme of all four of those methods of breaking from the 200-300K/yr income level is: leverage other people to work on your behalf. The most direct way to do that is to start a business. A slightly less direct way is to invest in existing businesses.
Microsoft investigates Windows Phone 7 data usage issues
From the Wired article:

Much of it is likely attributable to Twitter’s general counsel Alexander Macgillivray. As security and privacy blogger Christopher Soghoian notes, Macgillivray was one of the first law students at Harvards’ Berkman internet law center and at in his previous job at Google “played a major role in getting the company to contribute takedown requests to chillingeffects.org.”
Good idea, thank you.
so you don't believe people are ever principled, or are very rarely pricipled? Or do you believe that the people at twitter specifically aren't principled; and if so why?
Intel Announces New Patent Cross License Agreement with Nvidia
Hello HN,
I've been working for a year on this project called 9folds: a platform which allows creating websites, and templates.. on top of Google AppEngine.

I'd appreciate and comments and opinions
Looking at their map, it's highly misleading, implying there's CDMA 3G coverage in a bunch of places where there is no, or minimal coverage. (They're a trade body promoting CDMA -- what would you do in their shoes?)

CDMA2000 aka EV-DO isn't compatible with W-CDMA, aka UMTS -- the 3G standard used just about everywhere -- and has about 10% of the market worldwide:

https://secure.wikimedia.org/wikipedia/en/wiki/Comparison_of...

Here's a list of CDMA2000 operators. You'll notice a lot in the Americas, especially the USA, plus others scattered elsewhere:

https://secure.wikimedia.org/wikipedia/en/wiki/List_of_CDMA2...

And here's the giant table of UMTS (aka W-CDMA) operators worldwide:

https://secure.wikimedia.org/wikipedia/en/wiki/List_of_UMTS_...

If you're American and don't have a passport, then by all means get a Verizon iPhone 4. But if you expect to travel widely it'd be much more sensible to get a GSM/UMTS iPhone 4, even if it means putting up with AT&T at home. (More sensibly, buy an unlocked one from Apple on a trip to, say, the UK or Ireland: claim back the VAT and buy a micro-SIM on the network of your choice and you're golden.)

I don't understand how this gets dropped in every single article on this. They don't differentiate between different types of education. Patio wrote a great blog post about this recently, and there was a ton of HN discussion about it. The shortest answer is that not all the degrees are the same. All these studies really show that a lot of engineers, doctors, lawyers, and yes people in finance, make a good salary and are less likely to be unemployed. That does not mean that college is a good value for everyone. Many people would more likely benefit greatly from learning to be a plumber, mechanic, or other trade than getting a degree in american history. Sure, if you have the money to burn on the experience, fine. But, the idea that a degree in a non-professional field (especially if financed via loans) is worth it should be over.

All teas contain L-theanine. I too am skeptical about all of the health-information swirling around about teas these days, which is why I researched this topic and wrote about it.
Dear guy who doesn't allow comments on his site,

Maybe you should ponderate by total received content weight. It's not perfect but still give you a clue.
I mean, not just page size but images and css as well.
It depends not just on each tea, but each harvest of each tea since theanine levels are affected by levels of sunlight the leaves have received.

While your point is theoretically valid, the evidence in the academic literature suggests that the causal effect of education on earnings is roughly the same as one would get by doing a naive regression of earnings on education at the individual level. There's a bias with respect to ability, but it's on the order of 10 percent, and measurement error in education variables attenuates the naive estimates, balancing things out.

There are a number of natural experiments that caused specific groups to get more education than others. This evidence has led to a pretty broad consensus that the returns to one additional year of education are about 10 percent. See:

http://www.demog.berkeley.edu/~ebenstei/litreview/Handbooks/...
I think you are, perhaps, playing with the definition of causation in a strange way.

Causation is constant conjunction of events; that these things are correlative, and that there are other mitigating factors possibly leading to both at the same time, does not mean that there is not a causal relationship between them.

Correlation does not imply causation, but it also doesn't prohibit causation. None of the things that you listed really have an effect on a causative relationship between education and income (even though they might be contributing factors to both).

From a common sense perspective, quite a number of high paying jobs require a technical or professional degree. When you post a job listing, there are often educational requirements. If you don't have a college degree, the highest paying fields, such as doctor, lawyer, engineer... are completely closed off to you. With the industrialization of HR in modern companies, certain things, like years of education, are certainly used to 'weed out' candidates. (Try applying to an engineering job with just a GED).

Aside from that, the author isn't really implying a causal relation, he is just stating a strong statistical correlation. If you want to make a boatload of cash, chances are that getting an education is a good idea.
and he often beat me :)
I thought this was going to be about response time to a support request–which would be just as (or more) interesting.
My personal experience was that after trying to set up a connection to Sql Server 2000 for 2 days I tried to access via JRuby and had everything working in minutes.

Very pleasant surprise indeed.
Yes, that does seem a bit over-the-top, compared to the usual configure/make routine for Free software packages.

But is that the right contrast class?

I wonder how you feel about software that:

- refuses to run if it detects that it's running on a virtual machine (OS X)

- refuses to run if it detects that it's running under a debugger (iTunes)

- refuses to execute programs that aren't cryptographically signed by a particular vendor (iOS)

To me, a preachy message that doesn't actually interfere with running the program looks downright friendly by comparison.
Read the literal sense of the phrase.
The positrons (antimatter electrons) detected in this study are fairly easy to produce on Earth--certainly more cheaply than building satellites. http://en.wikipedia.org/wiki/Positron#Production Positrons are also produced in some radioactive decays as well as in accelerator experiments.
CEOs are a good example.

I like that you made a distinction between large and extremely profitable companies, because large companies often still pay their CEOs extreme salaries even when performance falters.

Case in point, Robert Nardelli at Home Depot made $123.7 million, excluding stock option grants, over 5 years from 2002 to 2007, while the company's stock price faltered. He was essentially fired and still got a severance package of $210 million. (http://en.wikipedia.org/wiki/The_Home_Depot)

Dick Grasso is another that comes to mind.

This is a huge and awesome milestone for the Cassandra project, and a big win for all its users. Congratulations all around for getting it out the door!
Unfortunately, I think the parent commenter is right -- your numbers are (currently) meaningless. Statistically, your sample size for estimating response time is 1 for each of those sites. You need at least a dozen or so monitor sites, preferably distributed in the same way that Internet users are, for anything meaningful information to be gained. Ideally, you'd also want to distribute your monitors taking peering agreements of the ISP, etc. into account for a truly representative picture of response times.

As it stands, you're doing a disservice to startups that aren't on EC2, for no good reason. You solution "works" on a technical level, but the data is statistically meaningless.
Despite my reading of HN, I've never really paid much attention to YC, but this data makes me ask:

To put this into practice, set a timer to go off every 60 seconds. At the end of this period, reflect back over the previous 60 seconds. By the end of the day you'll have become so good at reflecting that whenever you stay still in public long enough, random women will use you to apply their makeup.
$172,000 per year is not a yacht level income. It's a good salary (some might say great), but you're not going to have a mansion and a yacht.
For anyone serious about image production the cost of the software, like the cost of the camera and lenses is insignificant. For most photographers bit depth is only something they give much thought to when a client dictates (like a stock agency requiring a 16bit tiff, for example). For the vast majority of people just making images, 8 bit depth is perfectly fine. Most sensors in digital cameras are not anywhere near 16 bit anyway, more likely 12 or sometimes 14.

The photoshopessentails links below will obviously illustrate a difference (but not one that is very striking considering the destructive editing applied) - its a classic dynamic range compress/expand to show the benefits of higher quantization levels. Obviously that will degrade an image. Nobody, I suspect, is willing to show a side by side comparison of an image showing ordinary editing with rounding errors that make the slightest different to the image.

Most output is computer screens anyway where there is so much more impacting the image than rounding errors in editing stage. When you print an image that also introduces its own set of transforms, some have the benefit of making much that is visible on the screen (like moderate chroma noise) largely go away.

I dislike GIMP because it lacks the polish and sophistication of Photoshop but good photographs are good photographs, regardless of rounding errors in adjustment layers. When you look back at the last century of images, how many of those photos do you say would be improved had they more resolution, or less banding or whatever technical nonsense metric you want to apply.
I'm seriously debating pre-ordering one on February 3rd as I'm an existing Verizon customer. My only hold-up is whether or not they'll release and LTE version in June. Assuming Apple does have the hardware ready by then, what's the likelyhood of Verizon having a substantial LTE presence by then as well?

Does anyone know what their LTE coverage looks like or how soon it'll match their 3G coverage? I'm under the impression LTE is only in major cities at the moment.
