Myopie et intelligence.

Il a été montré par de nombreuses études sur les vrais jumeaux que la myopie est une pathologie qui dans la majorité des cas est déterminée génétiquement. On trouve une corrélation d’à peu près 0,25 entre la myopie et l’intelligence. Cette corrélation a été trouvée dans de nombreuses études menées par Sanford Cohn, Catherine Cohn et Arthur Jensen qui a montré que c’était une corrélation intrinsèque retrouvée au sein des familles de sorte que les adolescents à hauts Q.I avaient une plus grande prévalence de myopie que leur frères ou sœurs au Q.I moins élevé. Jensen a proposé que la raison de cette relation était pleiotropique, à savoir que les gènes responsables de la myopie augmentent également l’intelligence en augmentant la myélinisation du système nerveux.

La relation entre l’intelligence et la myopie fut déjà notée par Karl Pearson et Margaret Moul.

The open source authentication system OpenID is falling down on its knees. MyOpenID, a major registrar of free OpenID accounts will be closed on February 1st next year. The myOpenID service was launched in 2006 as a means for users to login to many sites by using a single account, their OpenID one, thus removing [...]

The post myOpenID to be shut down in 2014 appeared first on SecurEncrypt - HIPAA/HITECH File Encryption Software.

I wanted to reach out personally to let you know that we have made the decision to end of life the myOpenID service. myOpenID will be turned off on February 1, 2014.

So beginnt die E-Mail von Janrain CEO Larry Drebes an die Nutzer des von Janrain betriebenen OpenID Providers myOpenID. Weiter schreibt Drebes:

By 2009 it had become obvious that the vast majority of consumers would prefer to utilize an existing identity from a recognized provider rather than create their own myOpenID account.

Damit endet eine Entwicklung, die sich mit dem Launch von Facebook Connect Ende 2008 angekündigt hatte. Ich kann zwar nicht sagen, wie viele OpenID Provider noch existieren, aber ich behaupte mal kühn, dass es keine Hand voll mehr ist. Es verbleiben nur noch die großen Provider wie Google, die aber niemand mehr als solche erkennt.

Wouldn't it be great if you could use the same account to log in to multiple sites and applications, without having to trust them all with your password? Wouldn't it be even better if you could do this without having to hand ownership of your online identity over to some monolithic third party? (I'm looking at you, .NET Passport Microsoft Passport Windows Live ID.)

The good news is, you can! OpenID is a decentralised authentication system invented by LiveJournal but now being developed as an open standard under the careful mentorship of the Apache Software Foundation. Anyone can create an OpenID, and the number of sites which let you log in with one is growing by the day.

An OpenID is simply a URL. My OpenID is simonwillison.net, the address of my weblog. I can use it to sign in to any site that supports OpenID, and because I'm the only person with control over my weblog's homepage I'm the only person who can use that identity.

If you want your own OpenID (and you should), here's how to get one.

1. Sign up with an OpenID provider

OpenID is decentralised, which means that anyone can set themselves up as an OpenID provider. You can run your own server if you want to (phpMyID is one way of doing that) but there are a number of free services that will host an ID for you. Those include:

LiveJournal. They invented it, and if you have a LiveJournal account you already have an OpenID - it's the URL of your journal. I'm swillison.livejournal.com.

Vox - Six Apart's sexy new social network thang. I'm simon.vox.com.

VeriSign Labs, who have done some excellent work around OpenID and run a provider as part of their Personal Identity Provider service. I'm swillison.pip.verisignlabs.com.

MyOpenID, run by JanRain, authors of the most widely used OpenID libraries. I'm swillison.myopenid.com.

If you already have an account with Vox or LiveJournal you can skip straight to step 2. If not, pick the provider that you trust the most and create an account there. This isn't a permanent decision: you can move provider at any time without losing your account, provided you follow step 2.

2. Point your own site at your new OpenID

Here comes the magic. Having picked your provider and created an OpenID there, edit the HTML of your weblog's homepage (or indeed whichever URL you want to use as your personal OpenID) and add the following to the document <head>:

<link rel="openid.server" href="http://www.livejournal.com/openid/server.bml"> <link rel="openid.delegate" href="http://swillison.livejournal.com/">

Replace the openid.delegate href with the OpenID at your provider, and the openid.server href with that provider's OpenID server. You can find the server by viewing source on your OpenID page there, or by using this table:

OpenID ProviderServer URL LiveJournal http://www.livejournal.com/openid/server.bml Vox http://www.vox.com/services/openid/server VeriSign https://pip.verisignlabs.com/server MyOpenID http://www.myopenid.com/server

This delegation mechanism is key to OpenID's status as a truly decentralised authentication system. If you decide you no longer trust your identity provider you can switch to another one by just editing a couple of lines of HTML - your OpenID will stay the same.

3. Log in to something!

Now that you have an OpenID, you can use it to log in to all sorts of sites. Find their OpenID login form and enter your new OpenID - that's the URL of your weblog. You will be redirected to a page on your identity provider which will either ask you to log in or ask you to authorize the site to use your identity. Click "Yes" and you'll be sent back to the original site and magically logged in - no password required.

I've been collecting a list of sites that allow you to log in using OpenID under the openidconsumer tag; sites you may have heard of include Ma.gnolia, Zooomr and Wikitravel.

OpenID on simonwillison.net

This whole entry is a round-about way of announcing the addition of OpenID support to my weblog engine. You can sign in here; once signed in you'll be able to leave comments with a pretty OpenID logo (proving that they came from you) and track recent comments that you've posted on the Your Comments page. I'm working on adding other functionality for logged-in users such as the ability to edit your own comments or for trusted users to flag comment spam.

This kind of light-weight account mechanism is one of the things that makes OpenID so interesting. I doubt I could convince anyone to create a new account just to access a few features on my weblog, but if they already have an OpenID the overhead of logging in is small enough that I'm hopeful at least a few people will give it a go.

As always, report any bugs in the comments.
