555 days in a black-white world

Very long time no post here and is about time for an update.I setup a web server in my home machine register an account in dydns and created a personal website here.The site is in it’s early stage of development and it needs a lot of work to be done but feel free to comment and propose suggestions for it.Next week starts the new semester in my university which i am looking forward to it because i will attend two very interesting courses one in object-oriented programming using java and an another in cryptography and security of information systems.In other news i got added among with other great people in planet hellug which is an aggregation of blogs from the Greek community of open source.

I found a very interesting article here talking about what GPUs and drivers is needed to run Beryl in Linux.

As i wrote in my last post i wanted to find a way so that ath0 will start automatically on boot and dhcpcd configure it then.The solution to this is quite easy.The only thing i have to do is first create the script file with ln -s /etc/init.d/net.lo /etc/init.d/net.ath0 then add to /etc/conf.d/net this line config_ath0=( “dhcp” ) and last add it to the default runlevel with rc-update add net.ath0 default.

Recently i bought a D-Link AirPlus DWL-G520 Wireless PCI Adapter for one desktop machine i have.I manage to get it working in gentoo with wpa-psk following these steps.
First after i insert the card in the box i run update-pciids so lspci list the card
# lspci |grep Ethernet
01:08.0 Ethernet controller: Atheros Communications, Inc. AR5212 802.11abg NIC (rev 01)

Then i emerged net-wireless/madwifi-ng and net-wireless/madwifi-ng-tools to provide me the driver for the card.So with modprobe ath_pci the module is loaded.
# lsmod |grep ath
ath_rate_sample 12288 1
ath_pci 88416 0
wlan 188932 4 wlan_scan_sta,ath_rate_sample,ath_pci
ath_hal 189712 3 ath_rate_sample,ath_pci

Next as i read in the handbook here i have to emerge net-wireless/wpa_supplicant and edit /etc/conf.d/net as follows
modules=( “wpa_supplicant” )
wpa_supplicant_ath0=”-Dmadwifi”
and /etc/wpa_supplicant/wpa_supplicant.conf like that
# This is a network block that connects to any unsecured access point.
# We give it a low priority so any defined blocks are preferred.
network={
key_mgmt=NONE
priority=-9999999
}
# The below line not be changed otherwise we refuse to work
ctrl_interface=/var/run/wpa_supplicant
# Ensure that only root can read the WPA configuration
ctrl_interface_group=0
# Let wpa_supplicant take care of scanning and AP selection
ap_scan=1
# Simple case: WPA-PSK, PSK as an ASCII passphrase, allow all valid ciphers
network={
ssid=”**********”
psk=”**********”
# The higher the priority the sooner we are matched
priority=5
}

After that i run wpa_supplicant -c/etc/wpa_supplicant/wpa_supplicant.conf -iath0 -Dmadwifi -B to start the wpa_supplicant daemon and last i run dhcpcd -n ath0 so that ath0 interface takes an ip.
So far so good but now i have to find a way so ath0 will start automatically on boot and dhcpcd configure it then.Does anyone have any hint?(for the solution see my later post )

A good argument to switch to linux and to find where is your mind

Το site arstechnica έχει ένα ενδιαφέρον άρθρο στο οποίο παρουσιάζει την καινούργια έκδοση του firefox 2.0 RC2.Διαβάζοντάς το αποφάσισα να τον εγκαταστήσω.Μου πήρε βέβαια 1 ώρα(compilation γαρ) αλλά απο το τελικό αποτέλεσμα πιστεύω οτι άξιζε τον κόπο.Το καινούργιο default theme είναι απλά πολύ καλό το tab management πιο εύχρηστο και υπάρχουν και άλλες μικρές αλλαγές όπως ο καινούργιος add-on manager που βελτιώνουν τον firefox στα σημεία.Περισσότερες λεπτομέρειες υπάρχουν στα release notes του firefox.
