I really can't stand these audio based ads that Slashdot has started running, I have no problem with advertisement I think it actually adds to the experience, lots of stuff that I use I've found via ads. So please slashdot stop running these Microsoft server 2012 or what ever, or at least make them pay more, I mean I do notice them more when they start playing in some background slashdot tab.

A great inebriate hacker once told me "I schould build a content provider service, where the content is in the URL"... It took me about two years to understand what he ment, I think he ment that you can store data in "the cloud" or in the ether between the tubes. So I give openssl and some perl to make it look better:

echo "oh man where is this stored really? The intertubes?" |openssl base64 | perl -pne 'BEGIN{print "data:text/plain;base64,"} chop; END {print "\n"}'

Result:

data:text/plain;base64,b2ggbWFuIHdoZXJlIGlzIHRoaXMgc3RvcmVkIHJlYWxseT8gVGhlIGludGVydHViZXM/Cg==

This will link one hash to one file, so if two files have the same hash the latter will overwrite the formers name. Thanks to Perl oneliners and lost+found recovery for inspiration.

find -type f -print0 |
xargs -0 openssl sha1 |
perl -ne '
sub parsesha1{
$sha1=substr($_,-41,40);
$filename=substr($_,5,-44)
}

&parsesha1;

$file_hashes{$sha1}=$filename;

END{
foreach $hash (keys %file_hashes){
print "$hash:",$file_hashes{$hash},"\n"}
