RC5-64 Success!

As mentioned on Slashdot the Distributed.net effort has found the key in RSA’s RC5-64 challenge!

For those not familiar with the project, the security and encryption company RSA sponsored a contest to find a “key” to one of their cyphers. And, due to the nature of electronic cryptography, the only way to find the correct key was to try all the possible keys in the lock.

This technique would be similar to going to a Make-A-Key kiosk and having all the possible key combinations made for a padlock, then trying each key one-by-one. Eventually, you’ll find the right key to that lock. Because the method was only trial-and-error, even though you would have found the key to that particular padlock, the padlocks of the type would be no less secure.

RSA held this contest to demonstrate the power of a coordinated group of volunteers, and to encourage companies and governments to use the company’s more complicated cyphers. After all, you wouldn’t want your business’ secrets encrypted by an algorithm to which a group of volunteers found the key, eh? ;)

Omega-3 May Improve Mood

According to a recent study, eating foods in Omega-3 fatty acids may improve mood:

While additional research needs to be done to prove definitively omega-3s’ impact on different psychiatric disorders, some psychiatrists are now feeling confident enough to recommend that their depressed patients increase their consumption of these fatty acids. So, what are the best sources for omega-3s, and how much is needed to make a difference?

The best source for omega-3s is any type of seafood — including salmon, lobster and shrimp. For people who find seafood a bit fishy, walnuts and olive oil are also good sources for the fatty acid. […]

Hmm, I need to go to Sam’s Club this weekend anyhow to stock up on groceries, so maybe I should look into their fish entrees (instead of my usual chicken).

Frito-Lay to Make Snacks without Trans Fat

I first heard about this on NPR news during my drive to work yesterday, but I've finally been able to find an online citation as well. From MSNBC, “Frito-Lay to make reduced-fat snacks”:

Frito-Lay said that in early 2003 it will eliminate hydrogenated oils and convert to trans fat-free corn oil in Doritos, Tostitos and Cheetos. The company said the change will not compromise the taste of the snacks. […]

The company, the largest unit of Purchase, New York-based PepsiCo Inc., said it will launch Lay’s Reduced Fat chips and Cheetos Reduced Fat snacks in the near future. […]

The coming-addition of reduced-fat Lays and Cheetos is a nice bonus, though I’m especially pleased about their decision to switch to non-trans-fat oils. Maybe it’s becauase it’ll soon be required to list trans-fat on labels? ;)

Top Macro Beers

Through searching for more information on Michelob Ultra, I came across this page of the Best Macro Beers. That’s right — not the usual battle-of-the-micro-brews, but Macro Beers this time.

Not too surprisingly, Michelob Ultra isn’t anywhere on the list (though a few other Michelob brews are, which would explain the search-engine hit). In fact RateBeer’s reviews of Michelob Ultra are less than complimentary:

This was horrid. [&hellip]

would be good to drink while walking on a treadmill or at a health club […]

If you were to take 2.9 carbs worth of Michelob light [&hellip] then added 11 ounces of water, you would have Michelob ultra.

In addition to the Top Macro Beers list, RateBeer has several other useful top-lists:

  • Top Accessible Beers: This is different from the Top Macro category — Top Macro is based on brewery-size, while Top Accessible is based on the general availability of the beer.
  • Top American Beers: This list might be good to check out of curiosity’s sake, but good for little else. After all, why limit one’s self to only American beers?

Of the three (Top Macro, Top Accessible, and Top American), I think the most useful for everyday use would be Top Accessible. And, as is no surprise to me, Samuel Adams appears several times in that list :).
