Becoming concentrated again or: what are hackers drinking 2
<img src=”/img/beutelsbacher-lemon_juice.png “ alt=”“ align=“right” />Currently there are two most important liquids, which help me to survive in the jungle of living, hacking, going to school etc. The first thing is good dry red wine, the second thing is mineral water mixed with lemon juice.
The second thing is the reason for my post: just now, I’m feeling the ability of refreshing, which results of the consumption of mineral water with lemon juice. I approve to use hight quality lemon juice e.g. from a store, which sells ecological products (private tip: Beutelsbacher lemon juice). It tastes less acerbic and is more intensive in flavor and amount of vitamins.

Turandot by Puccini in the Opernhaus Stuttgart 0
<img src=”/img/turandot.png” alt=”“ align=“left” />Music is one of my subsidiary subject so it is a part of our school program to visit a opera performance. We plan to visit a classic opera and we decided to visit Turandot by Giacomo Puccini. It was really a bombastic firework of classical italian aria and subtle rezitations. The staging was adequate to the performed kind of music. It wasn’t disproportionate modern and also not too classical. The stage director seems to handle the contrast of historical story, which should be transported to a contemporary audience, quite well but until the end, the scenes get more and more drippy. But no problem, just close your eyes and enjoy the imposant music presented by famous artists.
It think its a good idea to prefer the opera sometimes, instead of watching a film in a cinema.

New useflags for glibc in Gentoo 0
glibc-2.3.4-20041102 comes with two useflags, I’ve never seen before. This could be a result of my blindness or the are really new. The first is nptlonly which disables the linuxthreads fallback option and build a glibc only with Native Posix Thread library. The second useflag is userlocales. It brings the possibility to specify in /etc/locales.build which locales should be build during the glibc-merge. This should increases the tempo of glibc build really much.
$ cat /etc/locales.build

New version of gmpc 0
<img src=”/img/gmpc-tooltip.png” alt=”“ align=“right” />gmpc (GNOME Music Player Client), a client for MPD (Music Player Daemon, I’ve reported) was released in version 0.11.2. The biggest visual change was the improvement ov the status-tooltip if you put the pointer over the tray icon. Nice work, guys!

Using tmpfs for /tmp 0
/tmp is often a place for a lot of garbage files. As a result, /tmp grows more and more and it would be a nice place, where race condition etc. can take place. Sascha Silbe pointed me on admin-issues@list.usrportage.de to use tmpfs for /tmp. This is quite a nice solution to prevent /tmp from being used as a sepulcher for data. tmpfs is a implementation which uses both, space in RAM and Swap, so there is no need to be afraid of performance problems.
Entry in /etc/fstab
none /tmp tmpfs size=30% 0 0

Encrypted swapspace 3
Since I’d found a solution to make my home-partition secure, I was bewilldered by another problem: whats about the swapspace? Swapspace is unsecure, if the attacker is in good luck, the key, which is used to encrypt the home-partition is clearly readable. Thats not a really secure thing, so I decided to encrypt swapspace too. I’ve used dm-crypt and a Key, which will be generated while booting the PC. The following init-script is a solution for Gentoo GNU/Linux.
#! /sbin/runscript
start() {
einfo “Generating random key and setting up encrypted swapspace”
head -c 50 /dev/random | uuencode –base64 /dev/stdout |
grep -v “^[begin|===]” | head -c 32 |
cryptsetup -c twofish -h plain create swap /dev/hda1
eend $?
einfo “Creating encrypted swapspace”
mkswap /dev/mapper/swap &>/dev/null
eend $?
einfo “Activating encrypted swapspace”
swapon /dev/mapper/swap
eend $?
}
stop() {
einfo “Deactivating encrypted swapspace”
sync
swapoff /dev/mapper/swap
eend $?
einfo “Unsetting encrypted swapspace”
cryptsetup remove swap
eend $?
}
Put the script above in /etc/init.d/encrypted-swap an do the following:
$ chmod +x /etc/init.d/encrypted-swap
$ /etc/init.d/encrypted-swap start
$ rc-update add encrypted-swap boot
The next thing to do is to make the RAM more secure. But currently I’ve no idea, which would be performant too.
