If true, this would allow people to see, in three dimensions, everything from genome transcription to the progression of cancerous tissue. With the FM-SEM’s level of resolution, these real-time views could lead to new and better treatments.&lt;/span&gt;&lt;/blockquote&gt;

&lt;blockquote class=&quot;tr_bq&quot;&gt;
&lt;a href=&quot;http://en.wikipedia.org/wiki/Mechanism_design&quot;&gt;Mechanism design&lt;/a&gt; (sometimes called reverse game theory) is a field in game theory studying solution concepts for a class of private information games. Leonid Hurwicz explains that &#39;in a design problem, the goal function is the main “given,” while the mechanism is the unknown. Therefore, the design problem is the “inverse” of traditional economic theory, which is typically devoted to the analysis of the performance of a given mechanism.&#39;[1] So, two distinguishing features of these games are: that a game &quot;designer&quot; chooses the game structure rather than inheriting one that the designer is interested in the game&#39;s outcome&lt;/blockquote&gt;

&lt;br /&gt;
D&#39;abord, on exporte la liste des chansons sur iTunes en format XML.&lt;br /&gt;
&lt;br /&gt;
J&#39;utilise R pour importer le fichier XML, le parcourir et faire un tableau de données avec le nom des chansons et leurs ratings.&lt;br /&gt;
&lt;br /&gt;

    values &amp;lt;- xmlSApply(r[[i]], xmlValue)
    name &amp;lt;- values[which(values==&quot;Name&quot;)+1]

data2$id=(as.numeric(row.names(data2))-1)
&lt;/code&gt;&lt;/pre&gt;
&lt;br /&gt;
J&#39;écris une fonction pour demander à l&#39;utilisateur quelle est la meilleure chanson parmi deux chansons tirées au sort.&lt;br /&gt;
&lt;br /&gt;
&lt;pre class=&quot;prettyprint,&quot; style=&quot;background-color: #eeeeee; border: 1px dashed rgb(153, 153, 153); color: black; font-family: Andale Mono, Lucida Console, Monaco, fixed, monospace; font-size: 12px; line-height: 14px; overflow: auto; padding: 5px; width: 100%;&quot;&gt;&lt;code&gt;

    roi &amp;lt;-data2[sample(nrow(data), 2, replace=F),]
    cat(&quot;Who wins?\n&quot;)
    cat(&quot;1. &quot;, roi[1,1], &quot;,&quot;, roi[1,2], &quot;\n&quot;)
    cat(&quot;2. &quot;, roi[2,1], &quot;,&quot;, roi[2,2], &quot;\n&quot;)
    x &amp;lt;- as.integer(readline(&quot; &quot;)) 
    if (is.na(x)){x&amp;lt;-0.5}
    if ((x==1)){
      
    }else if(x==2){
      x &amp;lt;- 0;
    } else {
      x&amp;lt;-0.5
    }  
    temp &amp;lt;- data.frame(Time=time, Song1=roi[1,4], Song2=roi[2,4], Winner=x)
    elodata &amp;lt;- rbind(elodata, temp)
    return(elodata)
  }

#elodata &amp;lt;- ranksongs(data2, elodata, 1)
load(&quot;ranking.Rdata&quot;)
&lt;/code&gt;&lt;/pre&gt;
&lt;br /&gt;
Cette fonction tourne en boucle.&lt;br /&gt;
&lt;br /&gt;
&lt;pre class=&quot;prettyprint,&quot; style=&quot;background-color: #eeeeee; border: 1px dashed rgb(153, 153, 153); color: black; font-family: Andale Mono, Lucida Console, Monaco, fixed, monospace; font-size: 12px; line-height: 14px; overflow: auto; padding: 5px; width: 100%;&quot;&gt;&lt;code&gt;
while(1){
  elodata &amp;lt;- ranksongs(data2,elodata,2)
  save(elodata, file=&quot;ranking.Rdata&quot;)
}
&lt;/code&gt;&lt;/pre&gt;
&lt;br /&gt;
Cette fonction de la librairie PlayerRatings permet de classer les chansons en fonction des combats menés.

&lt;br /&gt;
&lt;br /&gt;
&lt;pre class=&quot;prettyprint,&quot; style=&quot;background-color: #eeeeee; border: 1px dashed rgb(153, 153, 153); color: black; font-family: Andale Mono, Lucida Console, Monaco, fixed, monospace; font-size: 12px; line-height: 14px; overflow: auto; padding: 5px; width: 100%;&quot;&gt;&lt;code&gt;
music.rank &amp;lt;- steph(elodata, history=T)

&lt;/code&gt;&lt;/pre&gt;
&lt;br /&gt;
Je me demande combien de combats sont nécessaires pour bien classer les chansons. J&#39;ai hâte de voir si je vais arriver à classer mes chansons, modifier le fichier XML et réimporter les ratings dans iTunes...&lt;br /&gt;

Je vais essayer de coucher quelques idées sur le sujet. Voici d&#39;abord un petit vidéo d&#39;Andreas Schleicher sur TED.&lt;br /&gt;
&lt;br /&gt;
&amp;nbsp;
&lt;iframe allowfullscreen=&quot;&quot; frameborder=&quot;0&quot; height=&quot;360&quot; mozallowfullscreen=&quot;&quot; scrolling=&quot;no&quot; src=&quot;http://embed.ted.com/talks/andreas_schleicher_use_data_to_build_better_schools.html&quot; webkitallowfullscreen=&quot;&quot; width=&quot;640&quot;&gt;&lt;/iframe&gt;&lt;br /&gt;
&lt;br /&gt;
Voici quelques extraits qui me font réfléchir :&lt;br /&gt;
&lt;blockquote class=&quot;tr_bq&quot;&gt;
One way you can spend money is by paying teachers well, and you can see Korea investing a lot in attracting the best people into the teaching profession. And Korea also invests into long school days, which drives up costs further. Last but not least, Koreans want their teachers not only to teach but also to develop. They invest in professional development and collaboration and many other things. All that costs money. How can Korea afford all of this? The answer is, students in Korea learn in large classes. [...] You go to the next country on the list, Luxembourg, and you can see the red dot is exactly where it is for Korea, so Luxembourg spends the same per student as Korea does. But, you know, parents and teachers and policymakers in Luxembourg all like small classes. You know, it&#39;s very pleasant to walk into a small class. So they have invested all their money into there, and the blue bar, class size, is driving costs up. But even Luxembourg can spend its money only once, and the price for this is that teachers are not paid particularly well. Students don&#39;t have long hours of learning. And basically, teachers have little time to do anything else than teaching. So you can see two countries spent their money very differently, and actually how they spent their money matters a lot more than how much they invest in education.&lt;/blockquote&gt;
Il semble que que la taille des classes ne soit pas un facteur aussi important qu&#39;on pourrait le croire. C&#39;est plus nuancé que ça. Pourrions-nous imaginer un modèle plus éclaté? Pas de classe? Des classes de 100000 étudiants? Toutes ces réponses?&lt;br /&gt;
&lt;blockquote class=&quot;tr_bq&quot;&gt;
Everybody agrees that education is important. Everybody says that. But the test of truth is, how do you weigh that priority against other priorities? How do countries pay their teachers relative to other highly skilled workers? Would you want your child to become a teacher rather than a lawyer? How do the media talk about schools and teachers? Those are the critical questions, and what we have learned from PISA is that, in high-performing education systems, the leaders have convinced their citizens to make choices that value education, their future, more than consumption today. And you know what&#39;s interesting? You won&#39;t believe it, but there are countries in which the most attractive place to be is not the shopping center but the school. Those things really exist.
&lt;/blockquote&gt;
J&#39;espère que mes enfants vont grandir dans un monde où l&#39;on valorise plus les enseignants que les avocats.&lt;br /&gt;
&lt;blockquote class=&quot;tr_bq&quot;&gt;
But placing a high value on education is just part of the picture. The other part is the belief that all children are capable of success. You have some countries where students are segregated early in their ages. You know, students are divided up, reflecting the belief that only some children can achieve world-class standards. But usually that is linked to very strong social disparities. If you go to Japan in Asia, or Finland in Europe, parents and teachers in those countries expect every student to succeed, and you can see that actually mirrored in student behavior. When we asked students what counts for success in mathematics, students in North America would typically tell us, you know, it&#39;s all about talent. If I&#39;m not born as a genius in math, I&#39;d better study something else. Nine out of 10 Japanese students say that it depends on my own investment, on my own effort, and that tells you a lot about the system that is around them.
&lt;/blockquote&gt;
Il suffit de lire Outliers de Malcolm Gladwell pour saisir l&#39;impact d&#39;une ségrégation. Je suis si heureux d&#39;être né en février...&lt;br /&gt;
&lt;blockquote class=&quot;tr_bq&quot;&gt;
[...] what makes Finland so impressive is that only five percent of the performance variation amongst students lies between schools. Every school succeeds. This is where success is systemic. And how do they do that? They invest resources where they can make the most difference. They attract the strongest principals into the toughest schools, and the most talented teachers into the most challenging classroom.&lt;/blockquote&gt;
&lt;br /&gt;
Un pays où les plus forts choisissent les plus grands défis. Le Canada se classe bien en éducation comparativement aux autres pays. On a une bonne base, on est parmi les plus fort... il faut s&#39;attaquer au défi de l&#39;éducation!</description><link>http://fredcou.blogspot.com/2013/05/education.html</link><author>noreply@blogger.com (Frédéric Couet)</author><thr:total>0</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-1872584438799088071.post-1565117521226944140</guid><pubDate>Wed, 17 Apr 2013 00:54:00 +0000</pubDate><atom:updated>2013-04-16T20:54:56.444-04:00</atom:updated><category domain="http://www.blogger.com/atom/ns#">public</category><category domain="http://www.blogger.com/atom/ns#">R</category><category domain="http://www.blogger.com/atom/ns#">Science 2.0</category><category domain="http://www.blogger.com/atom/ns#">Visualisation</category><title>Les maisons à vendre sur Duproprio</title><description>Je me suis amusé à analyser les données sur &lt;a href=&quot;http://duproprio.com/&quot;&gt;Duproprio&lt;/a&gt;&amp;nbsp;pour les villes de Sainte-Foy, Sillery et Cap-Rouge. Voici d&#39;abord à quoi ressemble le prix des maisons et condos dans ces trois secteurs.&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: justify;&quot;&gt;
&lt;br /&gt;&lt;/div&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEinZdeKfOtxUcWJj9kW52aV9Y1_XQwehUX-SIe4hL30ky1A-RUmblj6nDBmXTJWfz1d8SG8xbECNCHM0jb4Qfbadmetp8y2ZLCHgt3MI3yJ4GVq5mSK8GI7lp-zx3EKe7TNTSB1P0axpMY/s1600/fig1.png&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEinZdeKfOtxUcWJj9kW52aV9Y1_XQwehUX-SIe4hL30ky1A-RUmblj6nDBmXTJWfz1d8SG8xbECNCHM0jb4Qfbadmetp8y2ZLCHgt3MI3yJ4GVq5mSK8GI7lp-zx3EKe7TNTSB1P0axpMY/s1600/fig1.png&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
&lt;br /&gt;
En moyenne, on vend sa maison ou condo à Sainte-Foy et Cap-Rouge pour 250000$ et Sillery pour 500000$...&lt;br /&gt;
&lt;br /&gt;
Maintenant, voyons voir si l&#39;on peut prédire le prix des maisons à partir de leurs descriptions. D&#39;abord, inspections les données.&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTFK7HQblotHKtHwBJORlc9CvGSA296bfAzjblMpGhCnYa0lwM3k3uQnGbcyPmCSPprh1ENdX5fDkWUP2dxT03xHDK9Q5XkeCaaqZf1ArD59uE2VEWAlyoDeSUSAjd-NYUGfb8EN1kZu8/s1600/fig3.png&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em; text-align: center;&quot;&gt;&lt;img border=&quot;0&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgTFK7HQblotHKtHwBJORlc9CvGSA296bfAzjblMpGhCnYa0lwM3k3uQnGbcyPmCSPprh1ENdX5fDkWUP2dxT03xHDK9Q5XkeCaaqZf1ArD59uE2VEWAlyoDeSUSAjd-NYUGfb8EN1kZu8/s1600/fig3.png&quot; /&gt;&lt;/a&gt;&lt;br /&gt;
On voit que le nombre de chambres, salle-de-bain et pièces sont les principaux indicateurs du prix des maisons. Quelques autres indicateurs sont disponibles, mais déjà la figure commence à être illisible...&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEggeVW9O_4GyDZdtPb-5xqlrlJz6B6oj7PfdZJzWiuzcgYtDy2SIQN3fIPdH3_xPWeD6pA7uDSs-jQYhTsxdXqnWy465PFTH235c4C17xfJmNilOZuC5dNd26mOmh7yrnZO6d03-H6iiiI/s1600/fig2.png&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEggeVW9O_4GyDZdtPb-5xqlrlJz6B6oj7PfdZJzWiuzcgYtDy2SIQN3fIPdH3_xPWeD6pA7uDSs-jQYhTsxdXqnWy465PFTH235c4C17xfJmNilOZuC5dNd26mOmh7yrnZO6d03-H6iiiI/s1600/fig2.png&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
Une simple régression linéaire nous permet de faire certaines prédictions. Notons les maisons identifiées 83, 192, 196, 112 et 18 qui coûtent moins cher que la prédiction du modèle.&lt;br /&gt;
&lt;br /&gt;
Pour le fun, voyons voir les données traitées par un algorithme de classification en arbre (régression). J&#39;utilise ctree.&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6MQzmgD7E7uNmeSB1eDICHv4y1QBSX4JaIarLvwX4SnJg_hdN-KIioFW-F8HUXdjQVTDrkPop0KX8ZIe6rB_SLxx_EZMUlJk-dk81JBxmGuX933KCtSc6NaVJkIhPKEOSPNZhiG3RdtM/s1600/fig7.png&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em; text-align: center;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;640&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEg6MQzmgD7E7uNmeSB1eDICHv4y1QBSX4JaIarLvwX4SnJg_hdN-KIioFW-F8HUXdjQVTDrkPop0KX8ZIe6rB_SLxx_EZMUlJk-dk81JBxmGuX933KCtSc6NaVJkIhPKEOSPNZhiG3RdtM/s640/fig7.png&quot; width=&quot;550&quot; /&gt;&lt;/a&gt;&lt;br /&gt;
&lt;br /&gt;
Intéressant. Si on génère des centaines de ces arbres, on se retrouve avec une forêt... C&#39;est l&#39;algorithme de randomForest. Voici des candidats intéresants : 192, 20, 196, 40, 178, 18. Ces points coûtent moins cher que les caractéristiques le suggèrent.&lt;br /&gt;
&lt;div class=&quot;separator&quot; style=&quot;clear: both; text-align: center;&quot;&gt;
&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOILirwClLtwwAs7JH6VPD8rVt8AJxYUEY7mj_w1p9KkTUHZng5aMYeRD8AFlAY0MsvGg9w6CU9gIVjLOh7yeaIxKSzFfhNPXJvMZdEfq0E_6wX0ctV65s9SyV4fBUjGby3E5d4hBjbIc/s1600/fig4.png&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em;&quot;&gt;&lt;img border=&quot;0&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgOILirwClLtwwAs7JH6VPD8rVt8AJxYUEY7mj_w1p9KkTUHZng5aMYeRD8AFlAY0MsvGg9w6CU9gIVjLOh7yeaIxKSzFfhNPXJvMZdEfq0E_6wX0ctV65s9SyV4fBUjGby3E5d4hBjbIc/s1600/fig4.png&quot; /&gt;&lt;/a&gt;&lt;/div&gt;
On peut utiliser la &lt;a href=&quot;http://fr.wikipedia.org/wiki/For%C3%AAt_d%27arbres_d%C3%A9cisionnels&quot;&gt;forêt d&#39;arbres décisionnels&lt;/a&gt;&amp;nbsp;pour estimer l&#39;importance des facteurs explicatifs. L&#39;aire habitable est l&#39;un des facteurs qui a le plus d&#39;impact. Ça a de l&#39;allure...&lt;a href=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhV5do-Ar46JZWuz0sYcBrjtH7HK1Row-ev7oL-Udn8jnyuuQJpqDEZuJ3ZGB5mBeKuf8btMrTb_Bz1JcvH5eJObH8KZPdkjQsODyIKEo8sGLTBTAhOYucbg3q-4hEnd0KLDJUmF8w6PeU/s1600/fig5.png&quot; imageanchor=&quot;1&quot; style=&quot;margin-left: 1em; margin-right: 1em; text-align: center;&quot;&gt;&lt;img border=&quot;0&quot; height=&quot;447&quot; src=&quot;https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhV5do-Ar46JZWuz0sYcBrjtH7HK1Row-ev7oL-Udn8jnyuuQJpqDEZuJ3ZGB5mBeKuf8btMrTb_Bz1JcvH5eJObH8KZPdkjQsODyIKEo8sGLTBTAhOYucbg3q-4hEnd0KLDJUmF8w6PeU/s640/fig5.png&quot; width=&quot;640&quot; /&gt;&lt;/a&gt;&lt;br /&gt;
&lt;br /&gt;
Voyons voir ces maisons.&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;http://duproprio.com/maison-mobile-a-vendre-ste-foy-quebec-393932&quot;&gt;http://duproprio.com/maison-mobile-a-vendre-ste-foy-quebec-393932&lt;/a&gt;&lt;br /&gt;
&lt;br /&gt;
Une maison mobile, ça part mal ;-)&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;http://duproprio.com/maison-mobile-a-vendre-ste-foy-quebec-249605&quot;&gt;http://duproprio.com/maison-mobile-a-vendre-ste-foy-quebec-249605&lt;/a&gt;&lt;br /&gt;
&lt;br /&gt;
Une autre maison mobile dans le même secteur. Il va falloir que j&#39;intègre un facteur pour tenir compte de ça...&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;http://duproprio.com/condo-a-vendre-sillery-quebec-231654&quot;&gt;http://duproprio.com/condo-a-vendre-sillery-quebec-231654&lt;/a&gt;&lt;br /&gt;
&lt;br /&gt;
Un beau petit condo à Sillery. Ouf. Pas pire.&lt;br /&gt;
&lt;br /&gt;
&lt;a href=&quot;http://duproprio.com/maison-a-vendre-ste-foy-quebec-346172&quot;&gt;http://duproprio.com/maison-a-vendre-ste-foy-quebec-346172&lt;/a&gt;&lt;br /&gt;
&lt;br /&gt;
Finalement un bungalow à Sainte-Foy autour de 300 000$. Ok.&lt;br /&gt;
&lt;br /&gt;
Dans le futur, il faudrait que je tienne compte de la géolocalisation... Mais de façon générale, je trouve que c&#39;est un projet intéressant.&lt;br /&gt;

&lt;br /&gt;
J&#39;ai écouté une présentation magistrale de&lt;a href=&quot;http://en.wikipedia.org/wiki/Lawrence_Lessig&quot;&gt; Lawrence Lessig&lt;/a&gt;. Son style de présentation est magnifique. C&#39;est l&#39;état de l&#39;art avec un mixte de rationnel et d&#39;émotion. Des diapositives qui ont l&#39;air faites par une équipe en communication. Un style où les diapos défilent rapidement pour créer un rythme entraînant. Un appel à l&#39;action puissant. Bref, c&#39;est très bien.&lt;br /&gt;
&lt;br /&gt;
Dans la présentation, on discute du &lt;a href=&quot;http://www2.publicationsduquebec.gouv.qc.ca/dynamicSearch/telecharge.php?type=2&amp;amp;file=/F_2/F2.html&quot;&gt;financement des partis politiques&lt;/a&gt;, un sujet assez&lt;a href=&quot;http://www.radio-canada.ca/nouvelles/Politique/2012/05/04/002-caq-financement-partis.shtml&quot;&gt; chaud au Québec&lt;/a&gt;. «Larry» discute du cas des États-Unis. Ce qui m&#39;accroche le plus, c&#39;est ce passage où il explique la place de l&#39;amour comme force motrice dans notre désir d&#39;améliorer les choses, même lorsque tout semble sans espoir.&lt;br /&gt;
&lt;br /&gt;
&lt;blockquote class=&quot;tr_bq&quot;&gt;
I spoke at Dartmouth once, and a woman stood up after I spoke, I write in my book, and she said to me, &quot;Professor, you&#39;ve convinced me this is hopeless. Hopeless. There&#39;s nothing we can do.&quot; When she said that, I scrambled. I tried to think, &quot;How do I respond to that hopelessness? What is that sense of hopelessness?&quot; And what hit me was an image of my six-year-old son. And I imagined a doctor coming to me and saying, &quot;Your son has terminal brain cancer, and there&#39;s nothing you can do. Nothing you can do.&quot; So would I do nothing? Would I just sit there? Accept it? Okay, nothing I can do? I&#39;m going off to build Google Glass. Of course not. I would do everything I could, and I would do everything I could because this is what love means, that the odds are irrelevant and that you do whatever the hell you can, the odds be damned.&lt;/blockquote&gt;
&lt;br /&gt;
Je pense qu&#39;on choisit d&#39;aimer. Quand on fait ce choix, ça change les gens et peut-être les sociétés.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
Un autre passage intéressant, c&#39;est lorsqu&#39;il explique l&#39;importance de son problème.&lt;br /&gt;
&lt;br /&gt;
&lt;blockquote class=&quot;tr_bq&quot;&gt;
So it&#39;s not that mine is the most important issue. It&#39;s not. Yours is the most important issue, but mine is the first issue, the issue we have to solve before we get to fix the issues you care about. No sensible reform, and we cannot afford a world, a future, with no sensible reform.&lt;/blockquote&gt;
&lt;br /&gt;
Certains sujets sont importants simplement parce qu&#39;ils représentent des fondations pour construire quelque chose de bien. Si le système est cassé, alors tous nos efforts peuvent paraître «definitely
and finally salao».&lt;br /&gt;

Pour avoir essayé les 3 programmes, je dois dire que c&#39;est de la bombe.&lt;br /&gt;
&lt;br /&gt;
Scilab est similaire à Matlab.&lt;br /&gt;
R est similaire à S pour les statistiques.&lt;br /&gt;
Maxima est similaire à Maple ou Mathematica.&lt;br /&gt;
&lt;br /&gt;
En équipe, ils peuvent faire des choses extra. Par exemple, on peut faire de la programmation génétique sur Matlab/Scilab, utiliser Maxima pour faire de la simplification algébrique et finalement utiliser R pour faire de la régression non linéaire.

&lt;br /&gt;
D&#39;abord, le gouvernement du Québec &lt;a href=&quot;http://www.radio-canada.ca/sujet/budget-quebec-2012/2012/11/21/004-hausse-taxes-cigarettes-reactions.shtml&quot;&gt;hausse les taxes sur le tabac&lt;/a&gt;.&lt;br /&gt;
&lt;br /&gt;
Ensuite, &lt;a href=&quot;http://blogs.hbr.org/cs/2012/11/americas_fiscal_cliff_can_be_a.html&quot;&gt;cet article&lt;/a&gt; pris sur le blogue du Harvard Business Review. Voici le passage que je trouve important :&lt;br /&gt;
&lt;blockquote class=&quot;tr_bq&quot;&gt;
The CDC (Center for Disease Control and Prevention) has estimated that the cost of smoking (estimated cost of smoking-related medical expenses and loss of productivity) exceeds $167 billion annually. The CDC has also estimated that 326 billion cigarettes (combustible tobacco, to be more precise) went up in smoke in 2011. In other words, every cigarette consumed costs the nation about 50 cents; every pack, $10.&lt;/blockquote&gt;
&lt;blockquote class=&quot;tr_bq&quot;&gt;
Put another way, while the smoker paid approximately $5 a pack up front, there was also an additional $10 secret surcharge — the cost of which is born by all of us (such as taxpayers, anyone who buys health insurance, even private companies who suffer from lower productivity as a result). It is as if we are telling the smoker, &quot;I know you can&#39;t afford to pay $15 for a pack. So we will give you $10 so you can afford to smoke.&quot; We are not this generous even with people who don&#39;t have one square meal a day.&lt;/blockquote&gt;
Si j&#39;interprète comme il faut, au Québec, 200 cigarettes coûtent autour de 80$. (Donc près de 8$ le paquet de 20 cigarettes?)&lt;br /&gt;
&lt;br /&gt;
L&#39;homme a un tel besoin d&#39;auto-destruction. &lt;a href=&quot;http://www.jarrete.qc.ca/&quot;&gt;J&#39;arrête&lt;/a&gt;.</description><link>http://fredcou.blogspot.com/2012/12/le-prix-des-cigarettes.html</link><author>noreply@blogger.com (Frédéric Couet)</author><thr:total>1</thr:total></item><item><guid isPermaLink="false">tag:blogger.com,1999:blog-1872584438799088071.post-6782966840955323676</guid><pubDate>Sat, 24 Nov 2012 01:39:00 +0000</pubDate><atom:updated>2012-11-23T20:39:51.419-05:00</atom:updated><category domain="http://www.blogger.com/atom/ns#">Physique</category><category domain="http://www.blogger.com/atom/ns#">Science</category><category domain="http://www.blogger.com/atom/ns#">Société</category><title>L&#39;émergence</title><description>L&#39;émergence m&#39;obsède.&lt;br /&gt;
&lt;blockquote&gt;
In philosophy, systems theory, science, and art, emergence is the way complex systems and patterns arise out of a multiplicity of relatively simple interactions. Emergence is central to the theories of integrative levels and of complex systems.&amp;nbsp;&lt;a href=&quot;http://en.wikipedia.org/wiki/Emergence&quot;&gt;Wikipedia&lt;/a&gt;.&lt;/blockquote&gt;
Certaines lois simples mènent à des structures complexes et magnifiques. Par exemple, à partir de quelques lois&amp;nbsp;d’interactions entre des cellules, on peut simuler la croissance de tissus et d&#39;organes.&amp;nbsp;À partir de quelques règles dans un réseau avec rétroaction, on peut créer des systèmes chaotiques très difficiles à prédire.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
&lt;blockquote&gt;
[...] while each of us will pursue our own individual dreams, we are an American family and we rise or fall together as one nation and as one people.&lt;/blockquote&gt;
Une touche sentimentale...
&lt;br /&gt;
&lt;blockquote&gt;
Michelle, I have never loved you more. I have never been prouder to watch the rest of America fall in love with you&lt;/blockquote&gt;
Un brin de vision...
&lt;br /&gt;
&lt;blockquote&gt;
But despite all our differences, most of us share certain hopes for America&#39;s future.  We want our kids to grow up in a country where they have access to the best schools and the best teachers.

A country that lives up to its legacy as the global leader in technology and discovery and innovation, with all the good jobs and new businesses that follow.

We want our children to live in an America that isn&#39;t burdened by debt, that isn&#39;t weakened by inequality, that isn&#39;t threatened by the destructive power of a warming planet.&lt;/blockquote&gt;
C&#39;est ce que j&#39;aimerais voir au Québec :
&lt;br /&gt;
&lt;blockquote&gt;
Tonight you voted for action, not politics as usual.&lt;/blockquote&gt;
&lt;blockquote&gt;
The role of citizen in our democracy does not end with your vote. America&#39;s never been about what can be done for us.  It&#39;s about what can be done by us together through the hard and frustrating, but necessary work of self- government.
&lt;/blockquote&gt;
Un peu d&#39;émotion :
&lt;br /&gt;
&lt;blockquote&gt;
I&#39;ve seen it in the family business whose owners would rather cut their own pay than lay off their neighbors, and in the workers who would rather cut back their hours than see a friend lose a job.&lt;/blockquote&gt;
Obama croit, je souhaite...
&lt;br /&gt;
&lt;blockquote&gt;
I believe we can seize this future together because we are not as divided as our politics suggests.  We&#39;re not as cynical as the pundits believe.  We are greater than the sum of our individual ambitions&lt;/blockquote&gt;
&lt;br /&gt;

&lt;br /&gt;
J&#39;avais commencé à explorer l&#39;acquisition vidéo avec un petit programme en Java et je disposais d&#39;un code 2D d&#39;éléments finis que j&#39;avais écrit pendant ma maîtrise.&lt;br /&gt;
&lt;br /&gt;
Entre temps, j&#39;ai eu d&#39;autres idées.&lt;br /&gt;
&lt;br /&gt;
Aujourd&#39;hui, je suis heureux de découvrir &lt;a href=&quot;http://creativemachines.cornell.edu/research/sketch/index.html&quot;&gt;cet outil &lt;/a&gt;de l&#39;Université Cornell. Un professeur pourrait faire un dessin 3D en quelques minutes devant la classe, appliquer des forces et des conditions limites pour visualiser les contraintes dans le matériau. Ce &lt;a href=&quot;http://creativemachines.cornell.edu/research/sketch/videos/video2Big.wmv&quot;&gt;vidéo &lt;/a&gt;(12 MB) en fait une démo très intéressante.&lt;br /&gt;
&lt;br /&gt;
L&#39;éducation du futur sera très puissante...</description><link>http://fredcou.blogspot.com/2012/10/realite-augmentee.html</link><author>noreply@blogger.com (Frédéric Couet)</author><thr:total>0</thr:total></item></channel></rss>
