LightTPD nightmare

antonio lorusso — Thu, 13 Nov 2008 12:08:56 +0000

if are trying to use mod_evhost in lighttpd in a more advanced way like using deep subdomains or with particulars tld like “co.uk” aka 2tls, you should know that
$HTTP["host"] =~ “^([^.]+)\.([^.]+)\.babelclient\.photobox\.([^.]+)\.([^.]+)$”{ evhost.path-pattern = “/web/%5/%6/assets” }
will NEVER WORK but
$HTTP["host"] =~ “^([^.]+)\.([^.]+)\.babelclient\.photobox\.([^.]+)\.([^.]+)”{ evhost.path-pattern = “/web/%5/%6/assets/” }
WILL WORK.

compare the two pieces of code and start screaming like a mad!

.bashrc not executed

antonio lorusso — Mon, 20 Oct 2008 09:25:34 +0000

Me and my friend Antonello, are going to start an experimental testing server to improve our skills in Ruby, PHP and start with Python as well.
After the installation, Antonello provided me an access created with webmin but, after the login I noticed that bashrc, actually bash, was not executed!
Editing /etc/passwd file, I was able to re-enable bash at login instead of sh:
your user line should look like
loginname:x:1001:1001::/home/antonio:/bin/bash
and not
loginname:x:1001:1001::/home/antonio:/bin/sh

F*#king Eclipse (Parental Advisory : Explicit Content)

antonio lorusso — Thu, 09 Oct 2008 13:20:10 +0000

This morning I had a lot of problems with my Eclipse Ganymede installation: svn plugin (subversive) refused to work properly… well, actually, it didn’t worked at all!!

After some time trying to understand the source of the problem, I came out with a GREAT IDEA : “I can remove some file from my workspace folder!!!” So I went there, I displayed the hidden folders, I entered in the .metadata folder and deleted all folders related to svn and team plugins and … you know what?? It f#*king worked…

I love how Eclipse doesn’t help in solving this… F%£k IT!

But, in the end, is a good IDE…

svn: Entry has unexpectedly changed special status

antonio lorusso — Mon, 29 Sep 2008 17:08:51 +0000

If you have this error after tryin a commit, for sure you have replaced a standard file with a symlink or viceversa, haven’t you?

In that case, what you have to do is just svn add and svn will replace the file with the new one!

Were you already scared ?

Anyway, the correct procedure is to replace a real file with a link in svn is the following:

svn remove of the file you want to link
ln -s
svn add of the new link

proper nfs umount

antonio lorusso — Wed, 09 Jul 2008 10:09:53 +0000

if you try to umount an NFS mountpoint this way
root:~> umount /mountpoint
and your shell answer this way
umount: /mountpoint: device is busy umount: /mountpoint: device is busy
then try killing all processes using the mountpoint and update the nfs export fs
root:~> fuser -k -m /mountpoint root:~> exportfs -au
at this point, you can safely umount
root:~> umount /mountpoint

peace!

in_array() in Perl?

antonio lorusso — Wed, 09 Jul 2008 09:57:51 +0000

I was looking for this useful function I always use in php and found this simple article.
Basically, the function that permit you to do that is grep used in this way:
my $string = ‘fin_helm’; my @array = qw/full_plate manteau boots two_handed_sword fin_helm/; if(grep $_ eq $string, @array) { print “$string is in the array”; }
easy?

just a note for me: Perl references

antonio lorusso — Tue, 08 Jul 2008 16:32:46 +0000

I said not to jump the chapter 4 of the Camel book (the Dromedary one) otherwise you’ll not know what @{…} (literally: at plus curly brackets) do!!
As explained in page 252, that expression, dereferenciate an array reference returning the array itself.
Remember that arghh..

ps. why Perl should be so complicated?

quick solution to “svn: Checksum mismatch …”

antonio lorusso — Wed, 11 Jun 2008 14:50:30 +0000

If this error afflict your quiet development day, I’m sorry I had this problem today and I solved in few steps:

make a backup of the working copy in a different directory
delete only the corrupted directory from your working copy
make an svn update
copy back only the modified files you need from the backup copy to the current working copy
commit your changes

Now breath deeply and take a cold shower: I suppose you must be sweat!
