  Setting a X property using xprop

I have spent quite some time figuring out how to use xprop -set as the man page is not really useful. I had a window with _NET_WM_WINDOW_TYPE(ATOM) = _NET_WM_WINDOW_TYPE_NORMAL and wanted to set this property to _NET_WM_WINDOW_TYPE_UTILITY.

[pterjan@plop tmp]$ xprop -set _NET_WM_WINDOW_TYPE _NET_WM_WINDOW_TYPE_UTILITY                            
xprop: error: unsupported conversion for _NET_WM_WINDOW_TYPE

So I thought that maybe it doesn't know how to resolve to atom:

[pterjan@plop tmp]$ xlsatoms |grep _NET_WM_WINDOW_TYPE_UTILITY
407 _NET_WM_WINDOW_TYPE_UTILITY
[pterjan@plop tmp]$ xprop -set _NET_WM_WINDOW_TYPE 407  
 xprop: error: unsupported conversion for _NET_WM_WINDOW_TYPE

At this point I started looking on google and could only find people asking and no answer...

Then a friend suggested me xprop -f _NET_WM_WINDOW_TYPE 32a -set _NET_WM_WINDOW_TYPE 407 which sort of worked but the result was _NET_WM_WINDOW_TYPE(ATOM) = 407. So I tried xprop -f _NET_WM_WINDOW_TYPE 32a -set _NET_WM_WINDOW_TYPE _NET_WM_WINDOW_TYPE_UTILITY and it worked!

So, when setting a property, you have to specify its format. I would have loved to read this in the man page.

  Terrorism

This is actually my second post with this title.

During this Week-End I have read Spook Country by William Gibson and one of the characters says something about terrorism which is so true but people tend to forget:

Are you really so scared of terrorists that you'll dismantle the structures that made America what it is?
[...]
If you are, you let the terrorist win. Because that is exactly, specifically, his goal, his only goal: to frighten you into surrending the rule of law. That's why they call him 'terrorist'. He uses terrifying threats to induce you to degrade your own society.
