23.5 / 24.0 is an improvement to both tests - and a significant improvement to the Threaded one.

Nexus One Fails to Satisfy Expectations
If you are correct then the previous quote saying a woman would give birth on average 10 times, expecting 3 or 4 to survive, then wouldn't the e5 be around 90? That's far better than in almost all developed countries...
I agree that WSJ, Economist, FT etc are excellent. But they all see the world through a certain angle (a business executive's, to generalize).

Personally I often agree with that angle, but I think it wouldn't be ideal to have high quality journalism written only from that specific view point.
I used to check the site of the News Ltd paper in SA a number of times a day but a couple of months ago I deleted all related bookmarks and feeds and went cold turkey. I don't think I'm missing much. They bow down to the pageview gods and, subsequently, the quality of their material is woeful.
I suppose something like this would find much of its use in places where neither FCC nor patents have a lot of clout.

"You can't buy a full-priced phone in any US store"

Actually, I always buy full-priced phones in US stores. In reverse chronological order:

- Motorola Droid purchased in a Verizon store for $579
- G1 purchased in a T-Mobile store for $499
- HTC Shadow purchased in a T-Mobile store for $449
- Sidekick (forget which one) purchased in a T-Mobile store for about $500

Every carrier lets you buy an unsubsidized phone. It's really not hard. It's just that Americans don't do it, for some reason.
Understanding Rainwater Harvesting Systems
Though the term rain water harvesting system makes it sound complicated, it is nothing but collecting rainwater, storing it for later use. Water being one of the most important elements of survival we should make the best use of the resources that are at our disposal. Australia is notorious for its water scarcity problems and the government is encouraging people to go for rainwater harvesting systems to help themselves and the government.

As a lawyer who studied the public choice theory

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

perspective on legislation when I was in law school, I recommend that everyone interested in public policy take a look at this article.

After edit: the other member of my household who is a HN participant and I were just discussing the submitted article. That reminded me to mention here that although many states require judges to be "learned in the law" (which in practice is interpreted as "admitted to the bar," which in turn means in most places to be someone who has passed a bar examination, which is only open to someone who has completed an accredited law degree), there is no such requirement for the United States Supreme Court. In principle, the Chief Justice of the United States could be a nonlawyer. A President would have to dare to appoint such a person, and the Senate would have to vote to confirm the appointment, but if nine suitable nonlawyers came forward to accept the appointment and were confirmed, the Supreme Court could consist entirely of nonlawyers. (If that happened, they might rely heavily on the help of their law clerks, but they might make some rather different decisions from any previous Court.)

1.9.2 is very nice indeed. 1.9.1 mostly solved my long-running-process memory leak woes, 1.9.2 solves them completely - I can now use Ruby for daemons without a second thought. I find this utterly delightful.

Add to that the cool ~20% speedup over 1.9.1 and this latest version of Ruby is a very exciting and compelling release indeed. I am glad Rails Core is throwing their weight behind it.
SocialCaptcha, a new fun spam fighter
Looking for an innovative new security feature on your website? Today www.SocialCaptcha.com enters Beta. Based on the premise that current CAPTCHAs too often incorrectly identify humans as spam bots, SocialCaptcha provides a fun user experience that humans should never fail. SocialCaptcha prompts users to identify their information from the social web in order to prove they're human. You guys are literally the first to see this, so we'd love any constructive feedback.

This may be a sign of something I was hoping would happen after Google made their superb move last week: that it would raise the bar for other Western companies. Yahoo can't not "take Google's side" without making themselves look abject by comparison.

Dialogues with Doug Engelbart
Fascinating phenomenon, but terribly written article. Who is Eggert? The article says that he is the person who led the team that discovered the temperatures and pressures needed to make a diamond liquid, but it doesn't give his full name or where he works. Nor is there a citation to where the source article appears in Nature Physics.

Ask HN: What are the best links that we've missed?
It might have been a bad headline. Maybe it got buried on Erlang day. Whatever the reason, sometimes quality submissions slip through the cracks.

Sometimes we catch these: RiderOfGiraffes excellent greybeard stories ( http://news.ycombinator.com/item?id=1001279 ) is one example - Khan Academy is another ( http://news.ycombinator.com/item?id=1059076 ), sometimes we miss stuff.

So HN - What have been your favorite submissions (either from you or someone else) that the rest of us overlooked?

EDIT: Probably best to link to the HN submission (include a direct link as well if you like)
Keep in mind the GIL is only a problem when you a) use threads and b) perform CPU-bound operations (unless you need soft real time)

When writing CPU-bound code, there are many libraries like NumPy that can do your heavy lifting in native code (thus avoiding the GIL)

So it really isn't as bad as it seems. The reason this patch is good, is because it prevents performance from falling apart if one of your threads takes up too much CPU.
While I wouldn't pay if I were Google either, and I won't be subscribing to the NYT, I think it's Google that derives the most business value from being able to index NYT content: they get answers to give to their consumers, and they get something valuable for "free" that they sell a large volume of ads against.
We are thinking about Android, not sure however if we can achieve the same smooth performance with the Android NDK. We also have strong demand for a PSN/PSP from Amiga fans in Europe. I guess all that will depend on the outcome of the iPhone release.

That uhm, wasn't part of his argument, that was his argument. And it's a fair one.

That said, all startup successes are statistical anomalies. The implicit irrational assumption is that you can beat the odds. Some companies beat harder odds than others, and being outside the valley does set them up for that.

There are lots of reasons one might not want or be able to move -- visas, family, other attachment to a particular place -- and that just has to become part of the calculation, "This makes it x% more likely that I'm just wasting my time, but I'm still [irrationally] convinced I can beat those odds."

We know that this works because there are examples of it. We also know that it's harder because of how relatively few there are.

Link to English version is top right of the page, 7500 Kroons is $747 AUD. That price is monthly, also. I'm not sure if you're from Sydney or not but the difference in real estate prices / bang for the buck is utterly astounding to me. Probably not that big of a deal if you're someplace else here more sane, but, yeah. Also note the included amenities etc (internet, cable, phone) all in the base price.

I have to add my love for Liberation Mono. https://fedorahosted.org/liberation-fonts/ Releases: https://fedorahosted.org/releases/l/i/liberation-fonts/

I recently had one of those "time to tweak my environment" days where I spent the entire day trying out monospaced fonts (DejaVu Sans Mono, Bitstream Vera Sans Mono, Envy, Terminus... everything I could find) in various color schemes in multiple editors (Win). I've now pretty much set any program where I need a monospace font to Liberation Mono 10pt.

However, I think Consolas looks better if I'm trying to fit more onto the screen. It looks better at smaller sizes than Liberation.

So I've settled on using 2 editors most the time with pretty similar features (Notepad++ & Programmer's Notepad), one loaded with Liberation Mono, the other with Consolas for files where I'd like to squeeze more lines in and keep decent readability.

Maybe there's a better way of doing things, but I like having two sorta different workspaces that I can quickly open.
Or he hates it. I've used Exchange, and the main reason I'd have written this about GMail instead of Exchange is that Exchange does too many things, poorly.

It's fine for email, in the sense that I would never use it for personal email and I don't care if it occasionally loses a piece of work email. But its scheduling makes its email processing look reasonable, in that it only occasionally loses a random piece of email, but it loses schedule items constantly.

This is, again, fine, because I only use it at work, and so when you say "Exchange lost it", you're surrounded by sympathetic people who constantly have the same experience. If I were, say, running a startup, I would actually care about not having my email system lose things constantly, and so I would avoid Exchange scrupulously.

I mean, maybe it's just been misconfigured in two or three large companies where I've worked? Misconfigured by professional system administrators, who don't hate configuring Microsoft products the way I do? If so, then it's hard enough to configure that I should never do it for myself. I'm a good programmer, but only an indifferent Windows admin.

For all of these reasons, it's possible that the OP didn't want to imply that "Exchange is solving the right problem" when he could instead be saying "GMail is solving the right problem." If it were me, that's what I'd be doing.
Is this surprising?

A Judge can't preside over suits against a company he's invested in. That's because we don't think anyone can render impartial answers to questions that affect them personally. But the average judge must have more invested in the legal profession than anywhere else.

Interesting follow-up questions:

- What goes on in a judge's mind when she rules on a question like this? Is she cynical about it? Does she just not think about it? Or does she rationalize with happytalk like "sacred ancient rights and traditions"? If she does rationalize, does that mean all such arguments are cynical at root, or are some power plays more cynical than others?

- What's kept this idea out of the journals until now?

- Does it bother you as much that doctors probably get better health care than the rest of us? That the children of teachers tend to get better grades? That airline pilots fly for free?
This is an excellent program, but I dislike that the presenter and one of the interviewees both say that chaotic systems are "inherently unpredictable". Chaotic (classical) systems are deterministic, so the same initial conditions will always give you the same result.

What makes them chaotic is that they are exponentially sensitive to initial conditions (i.e. "the butterfly effect"). This means that a difference that might go undetected in the initial condition can cause a potentially large change to the final result.
All I get is a google search results page. If there was a specific article, it would be a lot simpler if you just linked to it.
Most of what Bob says here is extraordinarily good advice, and goes for you whether you're selling software, a subscription service, or whatever. I've always been skeptical of one bit of it though:

Not being able to find a physical address, telephone number and business name within one click of the home page is a deal breaker for me when shopping for software: most people feel the same.

I trust Bob's gut right to the colon, but I need data to trust his gut after it, and he doesn't have it. Empirically, I sell to plenty of people without any of these things.

(Incidentally, the trouble with putting these trust signifiers one click from the home page is that normal users don't really care about any link from the home page aside from the ones which let them complete goals. If you're going to have a home number in the hopes of motivating people to believe you are a Real, Trustworthy Business, then put the thing prominently by decision points like your buy button.)

They may, but not everything is biased for lawyers.

For instance did you know that it is legal to discriminate against lawyers in housing? And not only is that discrimination legal, but it is actually common? You see lawyers tend to know what parts of the rental agreement are actually null and void, and can make themselves a PITA about it.

(I actually don't know how broadly this is the case. But I know it was the case in NYC several years ago. Based on the explanation I got from a friend who is a lawyer, I suspect that it is more generally true.)
I really like the code structure he advocates, and "midlayer mistake" is a terrible name for it. He names it by what it avoids.

My position is rather more stark than I made it out to be. I cannot agree with you that the decision between right and wrong must necessarily not be made with the rational mind.

Don't forget, emotions are just rationality in a different guise, in an evolutionary context. Take the extreme examples of love and hate: love help ensures the survival of genetic material close to your own lineage, while hate binds you to act - possibly violently (i.e. "irrationally") - if wronged, even if that is harmful to your own material position, in a kind of logic of mutually assured destruction. And of course, MAD is one of the more supremely rational approaches to the nuclear question, and is the primary reason why there hasn't been a WW3.

The problem with abandoning reason with respect to morals is that you will no longer be swayed by rational argument. For example, if you take your morals from the dead scripture of an old religion, you're locking yourself into a rational system of laws designed (largely) for agricultural societies which often didn't have an independent strong rule of law. If your attachment to this dead writing is strong, it will lead to profoundly unjust positions and outcomes, such as supporting the suppression of females in society, or discrimination against people "not like you" (gay, other religions, etc.).
Ahh, thanks for pointing that out. I am indeed on Ubuntu. And I'm obviously entirely clueless about fonts; ignorance is bliss. :)
Emotional arguments are rational arguments, but of a different kind. As I explain in my cousin posting to this (see reply to pingswept), emotions have rational reasons for existing. So we need not base our moral reasoning in emotions, but rather on the rational concepts behind those emotions, with no loss of generality.
Her article is wrong. NYC actually is missing engineers, or more accurately, missing internet-software-company-potential-employees. There are quantifiably more of these people in the Bay Area than there are in NYC. I don't have any numbers to back this up, but I actually think there are a higher percentage of "jack of all trades" programmers in NYC. In the Bay Area there are enough software engineers so that people can get much more specific about their areas of expertise. In NYC, there are fewer engineers, so people are forced to do a bit of everything.

Caterina Fake's real complaint is that she can't find one person to do three jobs at once for her at Hunch, which isn't surprising.
Random sampling for measuring performance
No, it's the specified behavior of a Unix pipe or socket[1]. If you want it not to block, you should set the O_NONBLOCK flag using fcntl(). Being "write ready" just means that it can take at least one byte in a buffer; it can't possibly be a promise not to block if you feed it a 2G buffer.

[1] But not disk files. Local disk storage isn't considered "blocking" if it simply needs to do a disk seek before returning the data. Most unix geeks end up finding this out experimentally at some point in their careers and using strong language. No, I don't know what they were thinking either...
True, but if it's impossible to measure the initial conditions to the necessary degree of accuracy, then it is quite legitimate to describe the system's behavior as "unpredictable."
Google: World-class PR. That's it. When something really hits their bottom line they will literally have no choice but to behave like every other corporation.

I agree with your assessment, but it kind of bothers me that it's the status quo that medical technology has such a high barrier to entry. IMO, it should be that if a doctor thinks that a tool is useful, then he should be able to use it. Just about any other professional would be granted this freedom.

I think however that this becomes more understandable in terms of pharmaceuticals, where there is clearly an element of danger associated with a lack of testing.
I was actually thinking of making a predictive model which would rate the new stories automatically. There are a lot of features that can be used in learning the prediction model: text length, content, etc. I already have the infrastructure more or less ready: http://www.wingify.com/contextsense/

In my opinion automatically rating posts will provide a useful filter to find stories that the community may have missed due to timezone/title issues.

What do you think about the idea?

You know, the world runs on oil, reserves of which are estimated by various parties with wild inconsistencies. And yet, people publish oil reserve figures over and over again, all around the world, and policy makers base the plans of their nations on that.

Glaciers in the world, and yes, in the Himalayas, are in retreat. (http://en.wikipedia.org/wiki/Retreat_of_glaciers_since_1850) The rate of retreat, given the seriousness and the surprise of the sound bite, may have been seriously and widely overestimated, and, yes, misrepresented. But in just the same way as the available reserves of oil are misrepresented to government officials everywhere (for they must be misrepresented some of the time, estimates being inconsistent, and varying over time: e.g. http://en.wikipedia.org/wiki/Oil_reserves#OPEC_countries)

Yes, it is a case study in the spread of alarmist claims, it should be a rallying call for more scientific integrity, but to emphasize the existence of a widely-cited, less than supported claim as evidence of systemic scientific malfeasance, when it is but one amid a sea of measurements, predictions and threats, seems to me to be falsely elevating the form of scientific inquiry above its function: to understand the world better than we other wise would, perhaps to make better decisions, perhaps just to wonder. It is, in other words, to miss the avalanche for the snowflake.
Women's Laptop Bags – Trendy and Stylish
This is good advice and a good indicator of why starting your own startup is the only sure fire way of making off like a founder.

I was offered to join the team for an early stage startup a few months ago and they offered 1% with salary upon funding. According to this article, all that risk and working for nothing for a few months until they got funding would have been a waste - I now have a few contract gigs that are paying me above market value (adjusted for sole proprietorship expenses like health &c...) for my work.

I basically work for a few months, then take a few off and do what I want - much more ideal than 9-to-5 and/or a high risk venture in which I'm not a founder...
