Speaking from knowledge of search engine indexing; you can't search on regular expressions because the search index is heavily heavily optimised and the only way to search for a regex would be to generate all the possible expansions and search for them individually. You could do it, it would just fuck up everyone's processes.
If you've done anything with SQL think about how slow wildcard text searches are compared to an indexed primary key search, then multiply by a couple of orders of magnitude since search engines throw away generality for extreme performance on a particular kind of search.
I've recently been trying to do something similar in C# (the other Java), and that syntax would be really handy.
For instance, pulling values out of an XML object if you want parent.element("person").element("addresses").element("work").element("line3").Value... but when the XML was parsed the person might not have any addresses, a word addres, or whatever is meant to be on line3. You have to check each level individually for null, which is a damn lot of code for nothing useful, or you write a helper function which either returns the final value or null if any of the hierarchy is null.
They've just put that in the language directly, which is fine by me.
I'm not a biologist, but sexual reproduction stirs the gene pool more. Without genetic crossover you're limited to variation directly by random mutation which is really really slow compared to randomly splicing half your genome with another viable genome from your species.
I think there's something good about having your genome jump around to make it a moving target for parasites too, otherwise you get problems like with potatoes and more recently bananas where the crop varieties are all clones and a single disease can wipe out the lot.
Furthermore, bdelloid rotifers are a kind of microorganism which has evolved to only reproduce asexually, and nobody has quite figured out how that works for them when it doesn't for almost every other species. The wikipedia page is sparse, but it will get you started if you're interested.
Guido doesn't know the photo you took is of the ballot you put in the box. Sure, if Guido wants to buy my vote I'll take his money and vote how I like.
I'm sorry, but after being drug to several 3D movies...
You probably mean 'dragged', but I love the image of one of your friends whispering "hey, watch this, he'll do ANYTHING after this, I bet we can even get him into some shitty 3D movie!" before spiking your drink while your back is turned.
From my perspective the important difference is that Blizzard is in a monopoly position with respect to Starcraft accounts whereas news services are fairly fungible and you can get any old account (or none) for The News.
I'm not up on the details of the RealID thing, but doesn't the id requirement extend beyond forum posts to other game functions like matchmaking and support? That's where I see the rub; choose between privacy and Starcraft versus choose between privacy and the ability to comment on a news site which is like all the other new sites. One is more coercive than the other.
You have a low slashdot id and a decisive tone; I expect you're right but I'd love to know why. Can you provide a link?
My layman's knowledge of cryptography tells me that compression and encryption algorithms both increase the apparent randomness of their output data relative to the input. I thought that with a decent encryption algorithm you shouldn't be able to get any statistical information about the plaintext as that leads to attack vectors, but maybe I misunderstand and you just can't get much information.
The charitable way to look at it is that each vendor writes a benchmark for the aspects of the browser which they think are most important, and those aspects are also obviously what they've put the most development emphasis on since they're regarded as the most important.
If you write a benchmark against your top development priorities and a rival eats your lunch despite having a different set of development priorities, you're probably not a top-tier vendor.
Off the top of my head, there's often an XML site map which google hits frequently to see what pages have changed. I can't see one linked anywhere on slashdot, but I think you can make one and submit it to google in your own time.
There is also a robots.txt file which allows crawlers to fetch a page every 100 seconds - I wouldn't be surprised if google crawls the slashdot frontpage for new articles every 200 seconds or so.
Another option is that google might have subscribed to the slashdot RSS feed - it's also extremely indexable. I don't know what the latency would be like on RSS.
Just had a cool/dumb idea: could you steer it slightly using the same paint-one-side technique they talk about for asteroids? Drop black dust on one side and it will melt faster in the sun due to lower albedo, then that side will release more fresh water and lose mass faster.
I know just enough physics to know that I haven't got a clue what the practical result would be if you did that. Obviously the effect would be very small compared to ocean currents, but it might be enough of a nudge to reduce the risk to shipping which could be very profitable for some groups.
When there was concern about the condition of the ozone layer, we ignored the obvious causes in favor of reducing hair spray and refrigerant.
What do you mean by this? As I understand it hair spray and refrigerant were the obvious causes, and having replaced the CFCs with marginally more expensive substitutes the ozone layer is now on the long slow road to recovery.
On the one hand I agree with you; on the other hand I've bought great games for the same cost as my daily commute to work. At that price I don't care if I don't Really Own it.
Briefly (and wrongly, but it will do for a slashdot reply), NP complete problems require the computer to actually calculate all of the possible solutions and see which one is best rather than than using an algorithmic shortcut. For every extra item that has to be computed the complexity increases by quite a large amount relative to the difficulty of the smaller problem. The traveling salesman problem is the classic example - adding another town to visit means you have to recalculate all the routes because there just might be a better solution using the new town in any part of the route.
Anyway, there's nothing impossible about NP complete problems - the issue is that they get very hard very quickly as you make the problem space bigger. Quickly the time required to find the best solution (not just a good one) would take longer than the remaining lifetime of the universe.
One of the tricks with NP complete problems is that if you're looking for a merely good solution, not the absolute best, humans can often use some heuristic tricks to home in on a good solution quickly while a dumb computer algorithm would still be chugging away looking exhaustively for the best solution. Studying the kinds of guesses that humans make in these situations is a notable area of study in artificial intelligence.
In summary, a computer will kick you ass at minesweeper, but it still won't be able to solve a 10^14 x 10^14 board before the end of time.
What's the problem with that? It just means the search space is comprised of some possible terrain with opportunity cost values instead of a fixed grid with straightforward build or movement cost values. Have you thought about this problem more or less than me?

Do I have to do everything for you?
without making any value judgement, 117 male births for every 100 female probably isn't chance.
Easy, all the particles would have tiny pointy beards if that were the case.

Why do you think that I see. How do you feel about that?
You probably mean 'dragged', but I love the image of one of your friends whispering "hey, watch this, he'll do ANYTHING after this, I bet we can even get him into some shitty 3D movie!" before spiking your drink while your back is turned.
Exactly! We have a designated source of nonsense. Ad-libbing will not be tolerated.

You mean 'anthropogenic' warming. You shouldn't call the warming 'anthropomorphic', it hates that.
You can have them as long as you take Russell Crowe too ;)
That's just an assertion. It depends heavily on the definitions of "I", "think", and "am". "Therefore" is probably ok.

Women want security, but they want a stud to father a child. No reason not to have both...
I think you're conflating 'best' with 'fittest'.
What kind of company do you think is fittest to survive in a totally free market?
