  1. Interesting, but not too exciting on The Emerging Science of DNA Cryptography · · Score: 5, Insightful

    Couple notes for people who haven't read the paper:

    1. Their scheme is not in-vivo (they're not actually working with DNA and proteins). It's a computational process that is based on the information transformations that occur inside a cell.

    2. It's kind of cute and nifty, but not particularly applicable. They discuss weaknesses in the attack, but in a pretty handwavey way. The core problem is that their "encrypted text" will include their entire plain text, just split up into pieces. Secondly, it doesn't seem to offer anything particularly new when compared to traditional block ciphers.

    3. Mathematically, this has nothing to do with biology. It's just loosely based on biological processes, and it's not really clear that these biological processes have anything particular to contribute to development of encryption. Transcription is just a mapping (from genomic DNA to mRNA), and translation is just a lossy mapping (from 3-tuples of mRNA to peptides). Mathematicians and cryptographers have been aware of generalized versions of these functions these for a long time (homomorphisms and reverse homomorphisms). There's not much new being introduced here.

  2. It's not that complicated on What Has Fox Got Against Its Own Sci-Fi Shows? · · Score: 0

    Let's say that Fox runs an awesome show that develops a dedicated fan following. That's bad for FOX, because they no longer have control over that market segment. Good shows take time and effort, and passion and dedication by good people who will in general expect to receive respect for their creative output. That's bad for FOX executives because they suddenly have to consider the opinions and needs of a bunch of plebes at the bottom.

    It's good to keep people hooked on perpetually churning set of "hot thing of the moment" shows based on replaceable talent and commodifiable appeal.

    I mean, who cares if the top star in American Idol has a beef with the producers and walks out? They'll just film it and make more money running a special "Sandra breaks down and leaves!" episode. It's beautiful.

    Good TV is a craft, not an assembly line. The assembly line is more efficient, it seems, and Fox has realized it.

  3. Re:Trouble is that even if you remove NULL-refs on Null References, the Billion Dollar Mistake · · Score: 2, Informative

    We're not talking about not having null references at all. Nullable references are in fact very useful in many situations, as you point out.

    The problem is that in many languages, it is not possible to describe a non-nullable type. I.e. a type that guarantees that the value it annotates is not null.

    This is useful because the vast majority of actual code doesn't really deal with 'null' references, and in fact will break if 'null' references are passed in. Right now, there are two ways to ensure your code is safe:

    1. make assertion-type checks everywhere. This is a pain in the ass to write and maintain compared to providing a non-nullable type. It's also slow to throw in unnecessary null checks everywhere during runtime.

    2. don't check aggressively, but ensure in an ad-hoc way that all not-null preconditions are met. Basically, you just make sure to never call the relevant methods with null values. This has the problem that you have to keep track of EVERY SINGLE PLACE a null may be introduced and eventually find its way into the method. This may be easy in simple applications, but can become very tedious in large applications.

    Providing a non-nullable type constructor saves all of those things. The compiler can ensure that a NULL never makes it into a variable marked not-null. You don't have to care about it. You can split your code up into the sections that are "pure" and sections that are "impure", and keep all your null-sanity-checking in the (what should be a relatively small) 'impure code', which calls into the pure code, with the compiler ensuring the calls are all valid.

    No work, just a simple type annotation. That's the potential.

    I realize it's somewhat cliche, but read the article. The current investigators were interested in this because hypothesized gas composition in volcanic eruptions would actually have been similar to the composition used by Miller. Furthermore, the article states that volcanoes often spur lightning strikes in the same area.

    So they're claiming that the atmospheric conditions near erupting volcanoes WOULD, in fact, be similar to Miller's original composition, and that this environment itself generates a diverse array of organic building blocks, as well as providing the context for lightning strikes that may have compounded these productions.

  9. Separate names for function versus physical device on Best DNS Naming Scheme For Small/Medium Businesses? · · Score: 2, Informative

    One thing we do in our internal network is to have two sets of names. One set is logically named and reflects a specific purpose. For example, "svn.internal.tld", "db.internal.tld", "web.internal.tld". 'svn' is the svn server, 'db' is the db server, and so on. The same machine can potentially be mapped to from many of these names (for example, 'svn' and 'db' may resolve to the same IP).

    When we write our internal scripts and configure our software, hostnames are ALWAYS specified using the logical function names.

    On top of this, each of the physical machines has a unique name for itself, following whatever arbitrary naming scheme we choose (in our case, it's fruits: lemon, orange, etc.). We use this name when talking about actual machines with problems (e.g. "lemon just went down").

    It works well enough for us. When we move services, we don't have to change our internal scripts or configuration at all, just change the dns reference for the given service. The nicknames allow us to talk about each individual machine easily.

  12. Re:There are many kinds of bananas on Bye Bye Bananas — the Return of Panama Disease · · Score: 1


    I grew up in Tamil Nadu.. close to the Kerala border (my family speaks a local dialect of Tamil mixed with Malayalam) and I just wanted to come in and nod my sad head at this fact.

    I remember at least 6 types of bananas directly. My favourites were the little tiny ones (like 3 inches long, yellow, and fat).

    Even discounting the bananas, there are dozens and dozens of fruit that I haven't had in years, and I miss dearly.

    Wandering around as 8-year old in my grandparents mango groves, picking ripe mangos straight from the tree, dried sap still fragrant on their skin, biting into it and scraping the flesh off the skin with my teeth.. that was pure fucking heaven.

    You saw where EVERYTHING you ate came from. I'd go play out on the beach and watch the fisherfolk bring in their catch on their tiny boats. Dragging their nets flopping full of fish back onto the beach from their boats. There'd be kids running around playing with the fish (myself included).

    The butchers we went to for mutton was a shack on the side of the street, fresh cuts of meat lying bleeding out in the open. If a cut wasn't available, they'd get a goat out from behind the shed and slaughter it right there.

    One sad things about north america is how the people in general are so profoundly disconnected from their food - particularly urbanites (I'm no different, I get my veggies and meat at the supermarket too). I think it makes a big difference in how you feel about your food, and how you treat your food habits. The few places where it's preserved on this content are on the ranches and farms - but that culture is slowly dying out.

    So it goes.

    By the way, it's still possible to find some good fruit in north america, you just have to change your fruit. Apples in India (esp. south india) are shit. All the ones I ever had were mealy and nasty. You get a superb apple selection in most supermarkets, from tart to sweet to crisp to fleshy. If you are attentive, you can find really nice quality: apples, pears, pineapple, oranges, grapes, plums, melons (canteloups to watermelon). Some of the melons are really hit and miss - sometimes it's shit sometimes its awesome.. I haven't been able to figure out how to tell if a melon is sweet before I buy it.

    I'm thinking a charge of manslaughter would be tenable as well. The persona she created was a weapon (whether it was physical or not, it was the instrument used to do the damage) she used against the girl. The question of intent, whether she consciously attempted to get the girl to commit suicide or not, is more muddled. The motive may have been just pure sociopathic glee she was deriving from torturing the girl.

    It's clear enough to any reasonable person that there was a high risk of injury or death as the result of the woman's actions, and she should have known that. At the very least, her intentional recklessness led to the forseeable death of another person. That sounds like solid basis for a charge of manslaughter.

    There's a fundamental difference you're missing. The application of logic in law is always with a presupposed conclusion.

    A defense lawer applying the logic of law MUST apply that logic in a way that it shows his client innocent or deserving of leniency - and that's his job. A prosecutor MUST apply the law's logic such that it shows that the defendant is guilty, and deserving of the punishment being sought. The conclusions are predefined.

    Science is not (at least ostensibly) supposed to be like that. You apply logic and you get the conclusions you get. If you're trying to bend it and twist it to somehow fit your hypothesis, or take you to some predefined conclusions, then you're fundamentally subverting the process.

  19. Re:yay! on Cracking Go · · Score: 2, Interesting


    True, but the richness of Go comes from the interplay of the moves permitted by an extremely SIMPLE set of moves. There are exactly 2 major rules and one minor rule in Go:

    1. you take turns placing pieces.
    2. pieces or groups of pieces "surrounded" by other pieces are captured.
    3. the board state cannot be repeated in two successive moves.

    From this simple specification emerges an amazingly beautiful game. There are particular structures and patterns which emerge with concrete properties, advantages and disadvantages. Watching interplay between these structures as a game evolves is like watching a dance.

    Now, this is all true for chess as well, but the ruleset for chess obfuscates it and hides it. Go takes the idea of a strategy game and strips it down to the barest essentials. That's what makes it so amazing for me. The sheer purity of it, the intuitiveness of the rules, and the depth of play that emerges from that.

    I'm an Indian. Chess is what I grew up playing. I love chess. I played it very frequently as a child and into my teens (and stopped playing after I got busy with school and also found it hard to find opponents in high school). I've spent hundreds of dollars on chess sets carved from ebony and sandalwood.

    All that said, Go blew me away when I learned it. I suck at the game, but every play is intense. At the end of every game I feel like I've participated in something majestic. More so than I ever felt with chess. Go is certainly a richer experience than chess.

    Here's the thing, there's probably not much that you need to personally apologize for (I'm guessing here.. I don't know you, who knows). What's missing is a national, formal acceptance of fault. Many in your country need to let go of the idea that accepting a mistake on the part of their country is tantamount to pissing on their graves of their ancestors.

    Without an explicit acceptance of what your country ended up doing wrong, there is little hope of avoiding a repeat of the exact same thing in some other context. How are you, as a nation, going to educate your children so that they don't fall for the exact same trap when some tragedy strikes their country when THEY are the electorate? How is it possible to do this when every single time someone brings up a criticism, some weasel pops out of the waxwork to distract attention towards irrelevant actions by others? How is your personal apology going to combat that?

    Your attitude seems to be one of putting things behind you and moving on.. which is understandable considering the embarassing trauma I'm sure you are suffering from.. but this is the wrong reaction to have. At the very least, your country owes it to the millions of people whose lives were ruined in part because of its actions, to examine what went wrong, reconcile with it, and put in place measures to avoid it. And don't for a second let yourself think that this expectation is somehow limited to just America. Every country has that obligation. Some may live up to that obligation, and others may not, but whether or not some other country holds itself up to a high standard shouldn't be a basis for excusing your own. It may seem to many that America receives an unfair amount of attention on this front.. but for christ's sake.. you're the most powerful nation in the world. Your influence affects EVERYBODY.. so OF COURSE people are going to scrutinize your actions more than the actions of others. You should welcome that, and rise to the challenge, and not run up a tree like a flayed cat.

    Now, I'm not sure abut your claim about America being the world's "greatest country", but I'd agree that your country has a many qualities that others could learn from, and that you have great potential.. for both good and bad. Your history is full of examples of both, and pointing out the bad does not detract from the good. Likewise, pointing out the good does not excuse the bad (and neither does pointing out the bad in others), and does not excuse the need for an honest self-appraisal amongst your citizens on the role their country plays in the world.
