Euler's Partition Function Theory Finished 117

Posted by Soulskill
from the that-was-quick dept.
universegeek writes "Mathematician Ken Ono, from Emory, has solved a 250-year-old problem: how to exactly and explicitly generate partition numbers. Ono and colleagues were able to finally do this by realizing that the pattern of partition numbers is fractal (PDF). This pattern allowed them to find a finite, algebraic formula, which is like striking oil in mathematics."

This is a case of following the money. ICANN info isn't going to be helpful, so get back to the root of who paid for the domain registration, and make it clear that it is different from the listed registerer.

I am however somewhat surprised by/skeptical about this story. How did the poster's name and info get associated w/ this? This sounds like an inside job or there's additional info missing from this story (which may be due to just trying to remain anonymous-ish).

There are ideographic relationships between concepts and what's in the characters. Each of the elements in complex characters bears some of the meaning of the word. Dictionaries for Chinese and Japanese Kanji are in fact organized in this manner (by character radical). I can't recommend a particular manner of memorizing them (i failed abysmally at the task as a child, and am functionally illiterate as a result), however the relationships are there if you want to look for them.

Happy to see a Google acquisition which has not entirely abandoned their existing userbase, as they are assimilated. The company i work for has picked up using etherpads here and there, and was intending on doing so further, until the acquisition. I guess we'll probably give the code base a run, and try installing an internal copy :) Rock on Etherpad & Google guys.

Oh, naïveté.

Nothing will stop them from filing their patent unless you are aware of their filing, and object.

Then, if you were to do something w/ your idea, they may very well sue you, regardless of their patent's invalidity, making the gamble that you'd rather settle than deal with the legal proceedings required to invalidate their patent.

These guys aren't doing it cause they're smart. They're doing it because they think there's easy money to be made, and it's a pain in the ass to defend yourself in court.

This behavor is called patent trolling. I figure any careful reader of Slashdot would recognize this modus operandi, given it's frequency in News for Nerds.

So what can i say?

Bugatti's Latest Veyron, Most Ridiculous Car on the Planet? 790

Posted by ScuttleMonkey
from the gas-guzzlers-that-make-your-eyes-bleed dept.
Wired has an amusing writeup that accurately captures the most recent ridiculous addition to Bugatti's automobile catalog. The $2.1 million Veyron sports over 1,000 horsepower, a 16-cylinder engine, and a top speed of 245 mph. The guilty conscience comes for free. "That same cash-filled briefcase could buy seven Ferrari 599s or every single 2009 model Mercedes. You could snap up a top-shelf Maybach and employ a chauffeur until well past the apocalypse. Hell, in this economy, $2.1 million is probably enough to make you a one-man special-interest group with some serious Washington clout."

Al-Qaeda Used Basic Codes, Calling Cards, Hotmail 285

Posted by Soulskill
from the if-only-the-nsa-watched-the-wire dept.
jd writes "In startling revelations, convicted terrorist Ali Saleh Kahlah al-Marri admitted that Al Qaeda used public telephones, pre-paid calling cards, search engines and Hotmail. Al-Marri 'used a '10-code' to protect the [phone] numbers — subtracting the actual digits in the phone numbers from 10 to arrive at a coded number.' The real story behind all this is that the terrorists weren't using sophisticated methods to avoid detection or monitoring — which tells us just how crappy SIGINT really is right now. If the NSA needs to wiretap the whole of the US because they can't break into a Hotmail account, you know they've got problems. FindLaw has a copy of al-Marri's plea agreement (the tech-related information begins on page 12), and the LA Times has further details on his case."

The original post AND all these comments miss the point.

File sharing is a means of distribution , NOT marketing .

If you are trying to get popular by being the top download on The Pirate Bay, then you're doing it wrong. In my experience, there is very little horizontal movement between pieces of content on torrent trackers. You go to the torrent tracker with something mind, you find it, you download it, you're done. Other media like SoulSeek are much better as an exploratory sharing system.

Nor are popular bands popular just because they're signed to major labels (otherwise Poe one of my favorite artists would be considerably better known than she is). They are popular because major labels and other soul crushing pieces of media machinery market them heavily through all the things that people are connected to. Television shows, movies, radio, the blogosphere, etc.

If you want to be popular, make yourself notable AND easy to get. Torrent trackers take care of the second bit. You've gotta take care of the first bit.

Er, way to troll? If you'd like to do your ridiculous hello world you can stick to:

And it's really unclear what "it" you're referring to. Because Ruby, for me, is a good blend of the things i wanted from Perl and Lisp with a side of Object Orientation. I get all the laziness and conveniences of Perl, and i can do all the crazy stuff i'd want to do with Lisp. So imo, you're way off base.

MacRuby matters for a lot of reasons. Early benchmarks aren't one of them. http://blog.headius.com/2009/03/on-benchmarking.html

MacRuby's potential for Cocoa integration is fantastic and great, and something i very very much want to see.

It's not clear however what relationship benchmarks at this stage (with an incomplete implementation) will actually correspond to in the future. They are a total red herring for discussion.

Look at MacRuby on the merits! not the benchmarks!

Increase In Xbox 360 E74 Problems 346

from the revenge-of-the-red-ring dept.
Xbm360 writes "According to data collected by Joystiq as well as Google Trends, there's been a steady rise in reports and discussion of the so-called E74 error on Xbox 360 consoles since August of last year. The E74 error is related to video problems caused by either a faulty AV connector or, more often, a loosened ANA/HANA scaling chip. This is not the first time the Xbox 360 has experienced technical issues; in recent years many people have complained about scratched discs and over-heating consoles — the 'red ring of death.'"

Consumers don't care about apple rumors. They can't buy rumors.

The only care about what products are available. Only fanbois and panicky investors care about rumors (normal investors should be in it for the long haul anyway).

Sort of an interesting read on why we should ignore mac rumors (and mind you i own 4 macs in my house and use them for dev, so i love 'em just as much as anyone), but otherwise a pretty pointless piece of reading.

I guess it's still better than idle.

Of course I don't think any of them imagined that it would have any effect on the bitterness over at Slashdot.

And i'm sure that they, like myself, were totally shocked at the rising of the sun again today. Can you imagine the odds!

TBH, i'm surprised to find so many positive comments (i, semi-jokingly, wonder about astroturfing).
