   <h1>Linux kernel</h1>

+      Started by Linus Torvalds in 1991 as a kernel for i386
+      PCs: <q>just a hobby, won't be big and professional like gnu</q>
+    </li>
+    <li>
+      Adopted as the kernel of the Debian system in 1993
+    </li>
+    <li>
+      After 20 years' development, supports more hardware
+      architectures and devices than anything else

+  <p>
+    The old model:
+  </p>
+  <ul class="incremental">
+    <li>
+      Each stable release had even second component.  Bug fixes and
+      minor features in stable releases with third component

+    </li>
+    <li>
+      Major development done separately, resulting in series of
+      unstable releases with odd second component (e.g. 2.5.50)
+    </li>
+    <li>
+      After a year or two, development resulted in a new stable
+      release
+    </li>
+    <li>
+      Problem: users waited years for new features, and then got many
+      more changes all at once.  Particularly bad in the 2.4-2.6
+      transition.

+	  git (and previously BitKeeper) made distributed development

+    <li>
+      Each 2.6.<var>x</var> release has stable update branch; releases
