Your take sounds plausible, but there are several conceptual inaccuracies:

1. Financial derivatives have no relationship to derivatives in calculus. (The two concepts are just coincidental namesakes.) A financial derivative is called a "derivative" because the price of a financial derivatives is _derived_ from the price of an underlying something. However, the price of the underlying asset is just one of many inputs into the price of a derivative on that option, so nobody is taking a "first derivative with respect to price".

2. It would be impossible to make a billion dollar bet on a penny stock using "plain vanilla" (regular) derivatives like options, because stock options are not offered on thinly traded penny stocks (because nobody cares about the stock, so nobody will care about the stock option, so an exchange won't invest in offering that stock option). The only way you could make a billion dollar bet on a penny stock is if you found an large institution or billionaire to make a customized bet with you about that stock (or a coin toss). However, there is almost no liquidity for a non-exchange-traded option of this kind.

3. A stock option and its underlying stock have an intimate relationship. An options trader will often buy or short a stock to hedge the risk s/he has from owning the stock option (and vice versa). An options/derivative trader definitely has to worry about how "unwinding a position" in one market will affect the other market.

From what little this article gives away, it seems to me like AOL are getting ready to further upset the newspaper industry online.

Employing lots of journalists ( and their communities ) seems a pretty smart move.

I wonder out loud, if communities are behind their favourite journalist, do you think that would make the members of the communities happier about paying for the news content?

I guess it depends on how much you believe communities are important to the journalist and equally how valuable the communities feel the journalists contribution to their daily lives are.

That said, I love reading the news but don't pay too much attention to who writes the news. ( Perhaps I should )

Anyone else got any ideas of what AOL might be upto with their army of journalists?

this is now my default window manager :]
To be honest, I hope they never "improve" Notepad (either of them: http://blogs.msdn.com/oldnewthing/archive/2006/03/28/563008....). I think every operating system needs a totally-bare-bones text editor. Because of that, I think Notepad does exactly what it's meant to do, and "improving" Notepad would change that.

WordPad, on the other hand... They can keep Ribboning the shit out of that for all I care.
Eliezer Yudkowsky and Roger Ebert.

I've never met either of them. I kind of grew up without a father, so both functioned as surrogates who lovingly fostered two things I've dedicated a lot of my time to -- writing and understanding intelligence.

Thanks for being awesome, if either of you read this.
I was a long term ion user and contributed code over several years to the project before switching to xmonad.

As I remember it, with ion you basically created your own layout manually. You'd make horizontal or vertical splits to divide up your workspace and then manually move windows around in to the resulting frames. It worked brilliantly: with a few keystrokes you could get exactly the windows you wanted in the order you wanted.

xmonad manages the layout for you, you don't have to do it manually. This means that when you create a new window xmonad automatically creates a new frame for it. To contrast, ion would add the window as a new tab of the current frame. If you wanted a new frame in ion then you'd have to create it.

The automatic layouts of xmonad are what make it so interesting, but you do need to spend some time getting them set up for the way you work. xmonad is without a doubt the most customisable window manager ever (which is both a blessing and a curse).

xmonad also works much better with other software than ion. This is a reflection of the developers behind each window manager. The ion developer had very strong opinions about everything and told anything he didn't like (like anti-aliased fonts, automake, GNOME, etc.) to f'ck off. The xmonad team are super-friendly and play well with others. xmonad has great GNOME support, for example.

I think I still prefer ion's way of working, but I strongly suspect that it's possible to duplicate it in xmonad, I just haven't done it yet. Maybe now that 0.9 is out I'll review my xmonad configuration.
Donna Matthews from a band called Elastica in the early/mid '90s.

I was living on the streets as I turned 20, and a chance encounter led me to hang out with the band at one of their early gigs. Donna made me feel pretty welcome and off I went on tour with them.

During the tour I started a fanzine to make money and help keep me alive. That fanzine was assisted by her (providing material) and I sold it to the fans.

The bit where it became more was after the tour had finished. How now to find money for food? I still had the fanzine but Elastica were on the cover and Elastica were not playing. I removed the cover, and would make a new cover according to whoever was in town headlining that night. Having the band on the cover is the difference between selling 20 copies and selling 150 copies.

Something about that first transformation from being on the streets to earning a decent wage off my own back has pretty much influenced every action since: I won't go back to the street, and there are always new ways to approach existing problems.

I could cite many more that are related to what we do, are more recent, are more obvious, etc... but none provided an epiphany greater than that first one.

I like the ranked feed and I like to have an option to see it unranked (as live feed). I wonder if FB has an option to set the default to either rank/unranked.
In the past many of my friends have these annoying applications that fortunately are not showed in the ranked news (may be because the algorithm learnt that I did not like them as I use to hide them).
Maybe it's just involuntary reflex.

I met someone who said he works as admin and complained he can't find a job in the town he lives (he commutes more than 4 hours a day). I couldn't understand that, but later in conversation I learned that he's a windows admin. Then I had the eyebrow rising involuntary reflex and everything became clear to me. Windows admin skills are kinda useless in town where most companies can't afford to use MS solutions where good open source alternatives exists, let alone employ many windows admins.
Ask HN: do you feel Google search result quality has gone down?
Yesterday I was surprised to find myself trying Yahoo search because I couldn't get satisfactory search results in Google. It was the first time in years. I started thinking about this, and I realized that in the past few months I haven't been getting particularly good results from Google. I don't get spam or anything, but a lot of times I don't get useful results.

The thing is, I'm not sure if it's because I do a lot of very specialized stuff these days, or because the search quality really has gone down. Consider these two examples:

Search for "Linux asynchronous IO". You'll get a lot of articles, but most are four years old (which is an eternity in the Linux world). These results aren't very good - posix AIO is implemented in userspace threads, and io_submit and friends don't work in many cases. Which cases? Hard to tell - I couldn't find any information in the results no matter how long I searched. I couldn't find any benchmarks either.

Perhaps it's because there is no good info on this on the web (hard to believe). So let's try something else - search for "concurrent hashmap in C". After hours of searching and playing with keywords, I got almost no useful results (other than Intel's libs, but not too much info on that either). It's difficult to believe that there are no good implementations out there.

So, is it the specialized nature of my searches, or is it Google? What do you think?
xmonad is more like awesome than ion, but closer still to dwm (http://dwm.suckless.org/), which is written in C.
The three habits of highly irritating management gurus
Yep. I never used to use search operators unless I was looking for something really specific. Nowadays I get completely irrelevant results and I am forced to quote strings and explicitly specify term precedence, conditionals and other regexy stuff.

Last night I was searching for the syntax of DEFTYPE when used with various types (i.e. MEMBER, SATISFIES, OR, etc.) and the #1 his for "deftype member" was the personal MySpace page of some guy.

I think they're optimizing for "social" results now.

PC vs. Mac deathmatch: Snow Leopard beats Windows 7
Yes.

One thing I noticed is that searches no longer require that all words in the query be present in the search results. Adding a + before a word is now required to ensure that it's present in results. That frequently results in me having to do 2-3 searches to find something that could previously be found with one.
Yep, I agree. Notepad should be (and is) the simplest possible GUI text editor. All the devs that I know use either Notepad2 or Notepad++ for more complex general-purpose editing.
I use OS X because I can keep my dev workflow while getting much nicer applications for everything else.
This is marginally relevant to HN, but I went ahead and posted it since it takes aim at some of the "advice" floating around out there with a cynical look at it.
It's not that Yes/No dialogs "doesn't work" at all, it's just that they don't work as well.

Yes/No options are easy to get confused over as soon as there's a negative in the question. A question like "Do you want to cancel the delete" with "Yes" and "No" options is easy to get wrong - is that"Yes, delete" or "Yes, cancel". You can work it out if you try, but there will be an avoidable percentage of errors using it.

Two buttons with "delete" and "cancel delete" on them is better.

In both cases you are "presenting several actions", they're just better labelled in the second case, so there's no added complexity to the user. To the coder, maybe, but making good UI's is what coders are paid to do.
You can replace Mod-X with a key sequence, for example C-m X. I blogged about it here: http://versia.com/2009/10/18/xmonad-metacity-gnome/
It's a hook to get attention, that's all. Have a title that sounds surprising and counterintuitive, then explain how you really meant something related but different. Would this have been submitted to HN if it argued "Programmers should automate tasks and learn new things" without the pretense? Probably not. It's one of the oldest tricks in the book. See also "worse is better", among others.

In the case of this article, though, I have to say that Larry Wall has already done it better with the "three virtues of a programmer":

Laziness: The quality that makes you go to great effort to reduce overall energy expenditure. It makes you write labor-saving programs that other people will find useful, and document what you wrote so you don't have to answer so many questions about it. Hence, the first great virtue of a programmer.

Impatience: The anger you feel when the computer is being lazy. This makes you write programs that don't just react to your needs, but actually anticipate them. Or at least that pretend to. Hence, the second great virtue of a programmer.

Hubris: Excessive pride, the sort of thing Zeus zaps you for. Also the quality that makes you write (and maintain) programs that other people won't want to say bad things about. Hence, the third great virtue of a programmer.
See also the discussion here: http://news.ycombinator.com/item?id=803201.
It's also aggravating that quotes don't allow matching of specific symbols within the quotes.

And, yes, the results are different. I'd agree with you they seem enhanced (eg., classified results) and fresher for popular culture, but somewhat worse for domain specific queries.
Dell 27" sells for 879 USD. Dell's 30" for about 1200 USD.

It's quite interesting how emotionally involved I got watching a couple of these. I had to stop because it was making me angry.

When I first read about the Prisoner's Dilemma in a Douglas Hofstadter book (probably Godel, Escher and Bach although I'm not sure) I went around reading everything I could about it as I felt it was saying something important about society. Today I'm not entirely sure that's the case but it still fascinates me...
This is an extreme example of my previous point: when is it a good choice to learn vs a complete waste of time.

I don't think anyone would write a web server unless they were in that business. But if they were, they wouldn't simply pick up Apache just because they can.

There are always at least two correct sides to every argument.
Can't agree more. Let's hope in the future we can choose to search for tech-specific results.
I have always had the habit of quickly editing the query if the top 5 results aren't what I was looking for, up to the point where I don't even really think about it, just adding some more keywords or sprinking a couple pluses, minuses or quotes. So I can't really tell if it has deteriorated in the past years.

However, I do think it could be possible that the pagerank algorithm does not scales good enough for the growth of Web pages, and especially with the "SEOs" out there always trying to come up with new ways to game the system.

Wow, not sure how I didn't even know that this existed! Thanks!
It has certainly gone waaaay south since day 1, that much is undeniable. Of course, a large part of that is that the internet has gotten a lot more useless filler in those years, and this has of course made 'relevant search' an astronomically harder problem than it was in 1998.

On the more important metric of 'has quality gotten worse in the last couple of years', I would say 'sort of'. The direct quality of results HAS suffered, but on the other hand, google have implemented the user-wiki thing that allows you to modify, to a degree, which sites are less relevant.

I will add that I think google needs to rethink it's keyword fuzziness, in the past it used to be acceptable if the results didn't exactly match what you were searching for, but these days that is becoming more of a problem. If I search for a bunch of words, I typically know I want those words, by all means suggest 'did you mean ... ?' but the fuzziness in the results needs to be pulled back.
Regarding the dumb thing, I think this quote says the same thing a bit more succinctly:

"In the beginner's mind there are many possibilities, in the expert's there are few" (Suzuki-roshi)
Apple plans to embed ads in operating system
The dell 27" is much lower-resolution, though.
They'd probably do well to have a seperate 'technical search' for searching for things related to technical matters, eg programming languages, physics, chemistry, medicine, engineering, etc. And remove the casual stuff (facebook, myspace, pages that are clearly not about a technical subject, etc) from that index.

It would probably be a highly praised feature to seperate off a second index like that, as specifically searching for programming language concepts and documentation can be difficult (the C# and .NET problem).
As I understand it Jackson disregards any data that wasn't gathered via a randomized, double-blinded, placebo controlled trial (RCT). Performing a trial with a placebo for flu vaccines has ethical implications because the flu vaccine has been proven effective. Possibly causing harm by not preventing the flu in subjects.

Another point in the critique is that Jackson's findings are based on seasonal flu and not pandemic flu. His findings are for people 60 and older, an age group not particularly targeted by the H1N1 flu.
Great, a new resolution with even _less_ vertical pixels.

You can modify the window client area colour, but relatively few applications respect it. Even Firefox running under Win7 switches to white text backgrounds in text entry areas like this very comment box; with theming disabled (and only when theming is disabled), it respects the user's choice of background colour.

I disagree, I use emacs with vertical splits (ie 1|2|3 layout) and 16:10 and 16:9 is great for that, also it means that spreading over onto the second (16:10) monitor isn't a change in layout policy.

I could never go back to 4:3 layout for programming, as I discovered last year when one of my 16:10s died and I had to use an old 4:3 I had laying around.
It's one of the reasons I'm switching back to Linux (from OS X) with my next computer purchase. Xmonad controlling my X-apps and the native OS X window manager controlling everything else is just unpleasant.

Ah - I'd always used the browser launch version, I wasn't aware they had .exe downloads.

I'm looking at it from a distance, trying to find some free time to play. A couple of questions:

2. On some screenshots you can clearly see overlapping windows, i.e. not all of them are always tiled?

Well, support for unix-style line ends would not hurt...
One good reason to run OS X is that there are several decent outliners (OmniOutliner, etc.). There are no good outliners for Windows, and I know of none for Linux either. There's the cross-platform JOE (Java Outline Editor), but it's not as good as OmniOutliner or the old Mac OS outliners (MORE, ThinkTank, Acta, INControl, etc.).

Conceivably, it could use bayesian logic to rank new submissions based on your previous upvotes and generate a list of submissions that you may be interested in.

It has been expressed in the past that HN explicitly makes the front page look the same for everybody because the moment you start hiding some items for some people, then community and voting become far less effective at maintaining the level of content.
