			<title>Tiny Core Linux 4.5</title>

						<description>&lt;p&gt;Es ist schon eine Weile her seit ich das letzte Mal mit &lt;a href=&quot;http://distro.ibiblio.org/tinycorelinux/welcome.html&quot;&gt;Tiny Core Linux&lt;/a&gt; gespielt habe. Nach der Installation startet Tiny Core Linux extrem schnell. Als Vergleich ein Start von &lt;a href=&quot;http://alpinelinux.org/&quot;&gt;Alpine Linux&lt;/a&gt; und einer von Tiny Core Linux in einer virtuellen Maschine.&lt;/p&gt;

&lt;p&gt;Alpine Linux: 12 s (bis Login)&lt;br /&gt;
Tiny Core Linux: 6 s&lt;/p&gt;

&lt;p&gt;Die Messung ist nicht ganz fair, denn eine Alpine Linux-Instalaltion ist etwas umfangreicher als die von Tiny Core Linux. Der Start von Fedora dauert aber in jedem Fall um einiges l&amp;#228;nger. Ausser ich verzichte auf den Start der grafischen Oberfl&amp;#228;che...der Vollst&amp;#228;ndigkeithalber muss ich mal die Zeit messen bis eine Minimalinstallation von Fedora bereit ist. Dem Gef&amp;#252;hl nach wird so sich etwa in der Gr&amp;#246;ssenordnung von Alpine Linux bewegen&lt;/p&gt;

&lt;p&gt;Sehr sch&amp;#246;n ist, dass bei Start von Tiny Core Linux eine Auswahl mit Window-Manager zur Verf&amp;#252;gung steht.&lt;/p&gt;</description>

						<description>&lt;p&gt;Wieder einmal hat jemand eine &lt;a href=&quot;http://lifehacker.com/5904069/five-best-linux-distributions&quot;&gt;Umfrage&lt;/a&gt; gemacht...repr&amp;#228;sentativ? Wohl kaum. Erstaunliches Ergebnis? Nein. Langweilig? Ja, sehr. &lt;/p&gt;

&lt;blockquote&gt;&lt;p&gt;Arch Linux  14.56%  (1,669 votes)  &lt;br /&gt;
Ubuntu (and variants)  51.15%  (5,863 votes)  &lt;br /&gt;
Linux Mint  15.78%  (1,809 votes)  &lt;br /&gt;
Fedora  8.44%  (967 votes)  &lt;br /&gt;
Debian  10.08%  (1,155 votes)  &lt;br /&gt;
 &lt;br /&gt;
Total Votes: 11,463&lt;/p&gt;&lt;/blockquote&gt;

&lt;p&gt;Fazit: Trau keiner Statistik aus einer Umfrage, welche du nicht selber &quot;optimiert&quot; hast, resp. stell einer Gruppe die richtige Frage und daraus resultiert das richtige Resultat.&lt;/p&gt;</description>

			<title>crunch and Fedora</title>

						<description>&lt;p&gt;&lt;a href=&quot;http://sourceforge.net/projects/crunch-wordlist/&quot;&gt;crunch&lt;/a&gt; is a wordlist generator. For test cases and demonstarations it&#039;s very useful to have a simple wordlist prepared to show how it works. I think that generating worklists is a missing feature for the &lt;a href=&quot;https://fedorahosted.org/security-spin/&quot;&gt;Fedora Security Lab&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;While compiling &lt;code&gt;crunch&lt;/code&gt; on Fedora 16 x86_64 I ran into an issue.&lt;/p&gt;

&lt;p&gt;&lt;code&gt;/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory&lt;/code&gt;&lt;/p&gt;

&lt;p&gt;Installing the corresponding package for 32 bit solves it.&lt;/p&gt;

&lt;p&gt;&lt;code&gt;sudo yum install -y glibc-devel.i686&lt;/code&gt;&lt;/p&gt;

&lt;p&gt;Be aware, the Makefile of &lt;code&gt;crunch&lt;/code&gt; will install the binary at a non-standard location.&lt;/p&gt;

&lt;p&gt;Let&#039;s generate some numbers&lt;/p&gt;

&lt;p&gt;&lt;code&gt;./crunch 9 9 0123456789&lt;/code&gt;&lt;/p&gt;</description>
