Hi,<br>
<br>
<br>
It has suddenly hit me, that there's no apparent reason to run most executables as 64 bits on a x86_64 machine. I mean, what for? It's not like I expect Firefox to address 1 GB of RAM. If it does, let it crash. On the other hand, plugins and other binaries for 64 bits is a headache. Flash player tops the list, I suppose.<br>
<br>
<br>
So it really makes me wonder: Why are the preinstalled binaries on a 64 bit machine, well, 64 bit executables? I run a 64 bit machine because I want the *overall* RAM to exceed 4 GB, but except for virtual machines, I don't expect any application to have problems with the 32 bit limitation.<br>
<br>

P.S. Just changed my Firefox to 32 bits. Had to install some libraries manually to get Flash Player going: yum install libpk-gtk-module.so libcanberra-gtk-module.so libcurl.i686 (thanks goes to strace as usual).<br><font color="#888888">
