  1. ggplot2 graphics library is fantastic on The Power of the R Programming Language · · Score: 1

    The power of R is in its libraries, which are often maintained by the best statistical researchers in that area.

    Recently I discovered the ggplot2 graphing library, which is a huge step forward for constructing graphs of all types in R. It's very well documented and very actively maintained.

  2. March 1991 Exploration and Exploitation? on The Curse of Knowledge Bogs Down Innovation · · Score: 2, Insightful

    If you like this stuff then you'll like this academic article:

    March, J. G. 1991, 'Exploration, and exploitation of organizational learning', Organization Science 2(1), 71-87.

    As I understand it March argues that new participants are required to learn new ways of doing things (just as the FTA does). March goes further though and argues that some kinds of organizations (often unconsciously) force 'rapid socialization' on new participants, bringing them in line with the groupthink quickly. He argues for a balanced socialization period, in which the organization can actually learn from the novel perspective (although not so long that the organization doesn't get back to exploiting its knowledge).

    There's lots of good literature citing this article too.

    @PDFPen and Preview re-opening, perhaps you should check out Skim.app:

    http://skim-app.sourceforge.net/

    It does auto re-reading for use in a LaTeX workflow, but it has a pile of other features, most obviously hugely improved PDF annotations and a great full-screen reading/note-taking mode. Persistent pop-ups for checking diagrams or screen-shots while reading text and roll-over pop-ups of link destinations (great for skiming and checking references in Scientific papers).

  5. Re:Only ourselves to blame on Australian PM Has Parody Site Shut Down · · Score: 1

    That's way to simplistic a take on Australian law.

    The Australian High(est) Court found an implied right to free speech in the Australian constitution. They ruled that since the constitution sets up a democracy, and free speech on political matters is crucial to a democracy, the Constitution therefore implies a right to free speech. I believe the case is known as Australian Capital Television v Commonwealth.

    I love a good implication as much as the next person, but an explicit protection would probably be of greater value, especially since the decision has been watered down by later court decisions, but the parent is still wrong.

    But study England's second innings totals (and the overs they used) and you see that they will need their longest innings yet to ensure the draw without the risk of seeing Langer and Hayden back in the middle (or would they open with Gillie? Not this summer I'm afraid). And if the aussies do get back in with at least a session England's going to want their highest second innings total too!

  8. End legal protection to get technical development on FCC to Reorganize 800mhz Band? · · Score: 1

    The situation with emergency services and interference is being approached the wrong way.

    These should be the services in which the message of open spectrum should be heard the loudest. Cognitive radios that cooperate to get the message through regardless of the environment of interference that they are in.

    Instead the FCC is doing the exact opposite---allocating more "don't interfere here, please" spectrum. Does making it illegal stop it? no, instead it makes the whole system vulnerable to people wanting to disrupt the emergency services. By the time the damage is done the legal process that enforces this is irrelevant.

    Think of this in a medical context and it gets scarier---a baddy with the right radio outside the hospital can effectively shut much of the hospital down.

    Gradually removing the protection for emergency services would properly motivate the development of cognitive and interference robust radio equipment. A well known phasing out of these 'protected bands' is the right way to do this.

  9. Re:Blame Homeland Security on U.S. Students Shun Computer Science, Engineering · · Score: 1

    This is true. Largely because there is lots of funding that requires that the employees be US citizens. Lots of defence and security work, but really work in all fields.

  10. is this the same thing as konspire2b (kast)? on RSS And BitTorrent, Together At Last · · Score: 3, Informative

    A million years ago (1998?) Wired published a whole edition on Push as the Next Big Thing. It was the first time I was really aware of them being totally wrong. Or perhaps just a bit ahead of their time.

    While I think this is a neater solution, there is another product that does exactly the same thing, allow you to subscribe to channels and received pushed content via incentive compatible (you get faster speeds if you upload more) swarms.

    It's called kast.

    So you are proposing an "intelligence" or "informedness" criteria on who should vote? So much for universal franchise ... Who, pray tell, should make this judgement?

    It is my experience that compulsory voting, as is done in Australia and some Scandinavian countries, results in a more politically engaged populace.

    When I say it is my experience I mean that---people in Australia are more engaged with the political process than they are in the states. I put this down to USians who don't vote ignoring politics in total, while Australians who know they are going to have to show up at the voting booth make at least some effect to know what they are doing when they vote.

    Frankly it ain't a complex decision---particularly in the first-past-the-post system in the States.

    It is not all about freedom---democracy requires some duties from citizens and voting should be one of those.

    James

    ps. Before you get all excited about being compelled to vote realize that in effect this means that you have to show up and have your name ticked off on the electoral role. They then give you a ballot which, if you'd like, you may smoke in the booth, or vote with.

    This reads as bizarre to me. I know nothing about the mechanics of Pinochet's rule but I fail to see how compulsory voting could do anything like this.

    Unless you are reading compulsory voting as "compelled to vote for one candidate" that is ...

    Compulsory voting doesn't mean that ... it simply means that every citizen must show up on voting day---and collect a ballot paper. You can smoke them in the booth if you'd like ...

    There is one wierdness.

    Due to the HFS filesystem not being case-sensitive if you install libwww-perl (which you will probably do when upgrading to 5.8) then it puts HEAD (a tool for manipulating http headers) in /usr/bin which stomps all over the familiar head.

    One to watch out for.

  19. .apps on OS X are folders. on iWarez · · Score: 1

    Applications are actually folders disgusied as double-clickable application icons.

    So you can store anything you would like within the (hidden) folder hierarchy that is the .app on OS X (think that this was present in NextStep as well)

    If you wanna see inside the folder, right-click (or cmd-click) and choose view contents. I'm sure that view contents is also in the menus as is usual for context menu items (nice to have but not neccessary).

    MS breaks the design metaphor by hiding SN away in other areas for their attempt at copy protection.

  22. Collaborative ontologies on The Google Effect And Domain Name Speculation · · Score: 1

    The human edited dmoz is very close to this. They give feeds to other directory packagers. Google packages the dmoz feed.

    They add value because dmoz is in alphabetical order not popularity or usefulness. Google restructures the order of the sites listed according to their page rank algorithm.

    I'd like to see a directory where you can customise the ontology (the structure of the categories). ie I drag a folder to another part of the tree and it fills up with different data which relates to that topic as it relates to the new category it is sitting under.

    To be more clear. Consider the topic "Interest Rates". Within the sphere of mainstream economics this should produce data on monetary policy and statistics. Within the sphere of consumer borrowing this should produce mostly comparative information on rates accessible to consumers. This is normally done by having two separate folders, one under each hierachy. But what if you get a site which is relevant to both. Do you duplicate or confine it to one? The hierarchy should be flexible metadata not a once and forever decision.

    And to go further one can then collaboratively filter ontologies. To use the most basic form (recommendations) "People who put ice cream under the category of "industry" also put milk under the category of supplier. People that think of capitalism as an "oppressive system" also think of "basketball shoes" under the category of Human rights.

    Hmmm. There's something here.

    Eloquence - do you think it would be possible to build a 'proof-of-concept' of a collaboratively filtered (well recommender-system) Google through a proxy server that routes one's Google searches.

    My itch is, rather than send an email when I find a page a friend might like, to have a way to 'flag' that page so that the next time my friend is searching on Google (and the flagged page would have shown up in the results anyway) it is high-lighted as having been recommended by me.

    I think that this could be built on a proxy server - has anyone tried this yet?
