Hegel li chiamava  &amp;#8220;personaggi cosmico-storici&amp;#8221;. Alcuni fondano dittature, altri salvano  vite umane, altri ancora, semplicemente, scoprendo o ideando portano  avanti la fiaccola dell&amp;#8217;umanità.&lt;/p&gt;
&lt;p&gt;Steve Jobs è uno dei tanti che hanno fatto avanzare quella fiamma con l&amp;#8217;immaginazione, l&amp;#8217;intuito e il coraggio.&lt;/p&gt;
&lt;p&gt;È  un uomo a cui Abilità e Caso hanno permesso di essere portavoce di  innumerevoli lampadine nascoste e mute nel torpore del nostro periodo  storico. Lampadine che vogliono cambiare il mondo e che, lentamente e  irreversibilmente, lo stanno illuminando.&lt;/p&gt;
&lt;p&gt;Non ho mai  apprezzato le sue strategie liturgiche, ma ho sempre, sempre rispettato  la sua intelligenza. Ogni cosa abbia toccato è diventata oro.&lt;/p&gt;
&lt;p&gt;E,  anche se forse non ce ne accorgiamo, da grande conoscitore di psicologia  delle masse, ci ha manipolati. Non tanto da venditore o da  imprenditore, quanto da capo spirituale, da Buddha. Un profeta che  indica la via.&lt;/p&gt;
&lt;p&gt;Quando vedremo l&amp;#8217;ennesimo film di  animazione in computer graphics, pensiamo alla sua Pixar, la prima a  compiere l&amp;#8217;ardito passo con Toy Story.&lt;/p&gt;
&lt;p&gt;Quando vedremo Samsung  annaspare a copiare perfino le strisicoline diagonali delle icone di  iPhone per i suoi tablet, pensiamo a lui.&lt;/p&gt;
&lt;p&gt;Quando ci verrà da dire &amp;#8220;One More Thing&amp;#8221;, sorridiamo, perché ci rendiamo conto di essere parte di un &amp;#8220;suo&amp;#8221; sistema.&lt;/p&gt;

&lt;p&gt;E, almeno una volta, ascoltiamo il suo manifesto-discorso a Stanford.&lt;br/&gt;Ne vale veramente la pena.&lt;/p&gt;
&lt;p&gt;&lt;em&gt; Stay hungry, Steve.&lt;/em&gt;&lt;/p&gt;

I mean really. You  can load music files into refreq, but also images (bitmaps, imgs, pngs).  When you load a song, first the program analyzes the track, then it  draws its &lt;a href="http://en.wikipedia.org/wiki/Musical_acoustics" target="_blank"&gt;frequency spectrum&lt;/a&gt;. After  tracking, you can generate the spectral image / bitmap back into music.&lt;/p&gt;
&lt;p&gt;At this point, it’s getting really interesting. After you have the  image of the track, how you want to play it depends on you, You can play  with the timeline, to play the sound from another aspect.&lt;/p&gt;</description><link>http://tumblr.spagnuolo.me/post/2143560872</link><guid>http://tumblr.spagnuolo.me/post/2143560872</guid><pubDate>Wed, 08 Dec 2010 15:44:00 +0100</pubDate></item><item><title>Visualization of QuickSort</title><description>&lt;iframe width="400" height="299" src="http://www.youtube.com/embed/vxENKlcs2Tw?wmode=transparent&amp;autohide=1&amp;egm=0&amp;hd=1&amp;iv_load_policy=3&amp;modestbranding=1&amp;rel=0&amp;showinfo=0&amp;showsearch=0" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;&lt;br/&gt;&lt;br/&gt;&lt;p&gt;&lt;strong&gt;Visualization of QuickSort&lt;/strong&gt;&lt;/p&gt;</description><link>http://tumblr.spagnuolo.me/post/2143454021</link><guid>http://tumblr.spagnuolo.me/post/2143454021</guid><pubDate>Wed, 08 Dec 2010 15:23:29 +0100</pubDate></item><item><title>The Sorter</title><description>&lt;iframe width="400" height="299" src="http://www.youtube.com/embed/2HjspVV0jK4?wmode=transparent&amp;autohide=1&amp;egm=0&amp;hd=1&amp;iv_load_policy=3&amp;modestbranding=1&amp;rel=0&amp;showinfo=0&amp;showsearch=0" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;&lt;br/&gt;&lt;br/&gt;&lt;p&gt;&lt;strong&gt;The Sorter&lt;/strong&gt;&lt;/p&gt;</description><link>http://tumblr.spagnuolo.me/post/2143449636</link><guid>http://tumblr.spagnuolo.me/post/2143449636</guid><pubDate>Wed, 08 Dec 2010 15:22:46 +0100</pubDate></item><item><title>Sorting Algorithm Animations, Code, Analysis, and Discussion</title><description>&lt;a href="http://www.sorting-algorithms.com/"&gt;Sorting Algorithm Animations, Code, Analysis, and Discussion&lt;/a&gt;: &lt;p&gt;These pages show 8 different sorting algorithms on 4 different  			initial conditions.  These visualizations are intended to:&lt;/p&gt;
&lt;ul&gt;&lt;li&gt; Show how each algorithm operates. &lt;/li&gt;
&lt;li&gt; Show that there is no best sorting algorithm. &lt;/li&gt;
&lt;li&gt; Show the advantages and disadvantages of each algorithm. &lt;/li&gt;
&lt;li&gt; Show that worse-case asymptotic behavior is not always the deciding 				factor in choosing an algorithm. &lt;/li&gt;
&lt;li&gt; Show that the initial condition (input order and key 				distribution) affects performance as much as the 				algorithm choice. &lt;/li&gt;
&lt;/ul&gt;&lt;p&gt;The ideal sorting algorithm would have the following properties:&lt;/p&gt;
&lt;ul&gt;&lt;li&gt; Stable: Equal keys aren’t reordered. &lt;/li&gt;
&lt;li&gt; Operates in place, requiring O(1) extra space. &lt;/li&gt;
&lt;li&gt; Worst-case O(n·lg(n)) key comparisons. &lt;/li&gt;
&lt;li&gt; Worst-case O(n) swaps. &lt;/li&gt;
&lt;li&gt; Adaptive: Speeds up to O(n) when data is nearly sorted or 				when there are few unique keys. &lt;/li&gt;
&lt;/ul&gt;&lt;p&gt;There is no algorithm that has all of these properties, and so the 			choice of sorting algorithm depends on the application.&lt;/p&gt;</description><link>http://tumblr.spagnuolo.me/post/1562525819</link><guid>http://tumblr.spagnuolo.me/post/1562525819</guid><pubDate>Sat, 13 Nov 2010 17:05:19 +0100</pubDate><category>sorting</category><category>algorithm</category></item><item><title>The sound of different sorting algorithms</title><description>&lt;iframe width="400" height="299" src="http://www.youtube.com/embed/t8g-iYGHpEA?wmode=transparent&amp;autohide=1&amp;egm=0&amp;hd=1&amp;iv_load_policy=3&amp;modestbranding=1&amp;rel=0&amp;showinfo=0&amp;showsearch=0" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;&lt;br/&gt;&lt;br/&gt;&lt;p&gt;&lt;strong&gt;The sound of different sorting algorithms&lt;/strong&gt;&lt;/p&gt;</description><link>http://tumblr.spagnuolo.me/post/1562448855</link><guid>http://tumblr.spagnuolo.me/post/1562448855</guid><pubDate>Sat, 13 Nov 2010 16:54:00 +0100</pubDate><category>sorting</category><category>algorithm</category></item></channel></rss>
