+# Legacy of the great wall 
+
+One day while dismantling (some (tiny part) of) this wall I took a 
+(much needed) pause and pondered...
+
+![Old wall](/data/blogs/legacy-of-the-great-wall/legacy-of-the-great-wall.jpg)
+
+Working with legacy software can be much like
+breaking down a wall. Hard, sweaty work for real men and 
+you literally have to bang something against it (the wall). I
+would advise against using your head for that, in opposition to
+when you are working with legacy software, where you very much
+have to use your head. Metaphors have their uses but are rarely
+perfect.
+
+The dog did not help much apart from pointing to an obvious place
+to start: The other end. And, of course, occasionally distracting me with
+a ball. An important task for a dog!
+
+Looking for seams and fracture planes is an obvious way to 
+explore the software, ehm - wall, to (t)ease the it apart.
+
+I've also heard that it is like eating an elephant (which
+nowadays might be considered wildly politically incorrect): One bite
+at a time. But it is of course not entirely irrelevant where you start.
+If you eat the foot first the elephant might fall down and hurt you 
+quite badly. The same thing could happen with some walls! But clearly
+you shouldn't run around and eat walls... 
+
+There's probably a zillion metaphors for working with legacy
+software. Sometimes it's 
+[like reading a book](/blogs/code-encounters-of-the-legacy-kind).
