Brunetta spamma per vendere il suo libretto
Anche io ho ricevuto lo spam del ministro Brunetta che mi invitava ad acquistare il suo libretto sulla “Rivoluzione”. Forse ha letto la denuncia dei redditi di Obama, pubblicata pochi giorni fa, contenente milioni di dollari di guadagni dalla vendita dei suoi libri ed ha pensato “vojo anch’io”.
Ricordo che questo tipo di pubblicità è vietata per legge, dal testo unico per la privacy art 130:
1. L’uso di sistemi automatizzati di chiamata senza l’intervento di un operatore per l’invio di materiale pubblicitario o di vendita diretta o per il compimento di ricerche di mercato o di comunicazione commerciale e’ consentito con il consenso dell’interessato.
2. La disposizione di cui al comma 1 si applica anche alle comunicazioni elettroniche, effettuate per le finalita’ ivi indicate, mediante posta elettronica, telefax, messaggi del tipo Mms (Multimedia Messaging Service) o Sms (Short Message Service) o di altro tipo.
Lo spam non è una cosa di poco conto, perché tanto la posta indesiderata si cancella: se tutti facessero come il Brunetta, la posta elettronica non esisterebbe e torneremmo ai fax.

Linux Installation
I’ve installed a Gentoo, following the http://www.gentoo.org/doc/en/handbook/handbook-ppc.xml ppc handbook. After a base installation, you can use my conf files to make your iBook G4 a real lovely GNU/Linux (Gentoo) home.
Kernel Config
Copy my .config file into /usr/src/linux (or wherever you did copy the kernel source files) and do a
[sourcecode language=”java”]make oldconfig[/sourcecode]
Config-2.6.9-sleep
make.conf
This is my make.conf file:
make.conf
Xorg
I’ve managed to make 3D acceleration with DRI work and VGA out, also together.
So, If you want to use 3D acceleration without MergedFB or Xinerama, take my xorg.conf
This option make a faster 3D acceleration, but video output will not work.
But if you want to use Xinerama with dual head configuration, without 3D acceleration (both clone mode and one screen left of the other), you want to use that:
Xorg.conf.dual with a cvs or => 6.8.2 Xorg version (because you need these xorg radeon patches https://bugs.freedesktop.org/show_bug.cgi?id=2064, merged only in newer xorg versions. If you don’t want to overwrite your existing xorg version, you can build xorg from cvs as in this xorg-cvs-howto.txt , with my host.def.
NB: if you want to have the two screens spanning on OSX you must patch your iBook with that http://www.rutemoeller.com/mp/ibook/ibook_e.html Spanning Patch Ibook: I suggest you to do that if you know what you’re doing. It’s not necessary if you use only Linux.
I made MergedFB working, so now I have a clone mode (VGA out is the same of the TFT) with 3D DRI acceleration.
You must use this simple configuration:
xorg.conf.merged
NB: These 3 configurations are alternative, you can use one.
Make the Apple key works as Altgr and the keyboard more linux confortable
My Apple G4 12″ doesn’t have any Altgr Key, so it’s impossibile to write composed symbols as @ or #. To correct this problem, you can do this procedure on Gnome:
1. Computer -> Desktop Preferences -> Keyboard
2. “Layout Options” tab
3. In the right-hand list open the “Third level choosers” group
4. Highlight “Press Left Win-key to choose 3rd level”
5. Click “Add”
Or add this to keyboard section on /etc/X11/xorg.conf file:
[sourcecode language=”java”]”XkbOptions” “lv3:lwin_switch”[/sourcecode]
My xorg.conf file keyboard section is:
[sourcecode language=”java”]
Section “InputDevice”
Identifier “Keyboard0”
Driver “keyboard”
Option “XkbKeycodes” “macintosh”
Option “XkbSymbols” “macintosh/us”
Option “XkbGeometry” “macintosh”
Option “XkbOptions” “ctrl:nocaps, lv3:lwin_switch”
Option “XkbRules” “xfree86”
Option “XkbModel” “pc105”
Option “LeftAlt” “Meta”
Option “RightAlt” “LWin”
Option “XkbLayout” “it”
EndSection
[/sourcecode]
On the US keyboard, the ~ and +/- keys aren’t mapped correctly.
add these lines to a startup script:
[sourcecode language=”java”]
xmodmap -e “keycode 49 = section plusminus”
xmodmap -e “keycode 94 = quoteleft asciitilde”
[/sourcecode]
Three Button Mouse Emulation
I usually use an external USB three button mouse, but I want to have an alternative access to the middle and right button without the external mouse.
To use an alternative key to emulate the mouse buttons, you must do:
[sourcecode language=”java”]
echo “1” > /proc/sys/dev/mac_hid/mouse_button_emulation
[/sourcecode]
The standard keys now are on Fn+CTRL for middle button and Fn+alt for right button.
If you want to change the keys, you must do:
[sourcecode language=”java”]
echo “68” > /proc/sys/dev/mac_hid/mouse_button2_keycode
echo “87” > /proc/sys/dev/mac_hid/mouse_button3_keycode
[/sourcecode]
Remember, you must do these commands every boot, so you can add to an init script.
You can change the keycodes 68 and 87 writing your own. To view what keycode is a button press you can use:
[sourcecode language=”java”]
xev
[sourcecode language=”java”]
If your distro supports /etc/sysctl.conf, you can add these lines to this file:
[sourcecode language=”java”]
# Mouse button emulation:
dev/mac_hid/mouse_button_emulation = 1
#dev/mac_hid/mouse_button2_keycode = 68
#dev/mac_hid/mouse_button3_keycode = 87
[/sourcecode]
Uncomment the last lines if you want to edit the keycodes.
Pbbuttons
In order to make the keyword and the power management more usable, i use pbbuttons:
[sourcecode language=”java”
emerge pbbuttonsd
rc-update add pbbuttonsd default
[/sourcecode]
Now you must configure the /etc/pbbuttons.conf file. Here is mine:
pbbuttonsd.conf
Sleep
Kernel 2.6.11 comes with support for putting the iBook G4 to sleep. However you still have to enable it when configuring the kernel.
Benh has released a patch that supports Apple iBook g4 sleep: you need it if you have a kernel version < 2.6.11.
http://forums.gentoo.org/viewtopic.php?t=254232&highlight=benh+patch
You can find the 2.6.9 patch version also here:
albook-ibookg4-sleep-5.diff
Just apply it to kernel source with
[sourcecode language=”java”]
cp ./albook-ibookg4-sleep-4.diff.gz /usr/src/linux
cd /usr/src/linux
gunzip ./albook-ibookg4-sleep-4.diff.gz
patch -p1 < albook-ibookg4-sleep-4.diff make menuconfig [/sourcecode] And add the Powerbook Power Management in the Drivers -> Macintosh kernel configuration section
After that, you can use pbbuttons to make the iBook sleep when the LCD is closed.
pbbuttonsd.conf
Power
Some problems with sleep function comes from modules loaded (usb, thermal, etc). You can solve them if you use powerprefs. Before going to sleep, your iBook must do:
[sourcecode language=”java”]
lsmod | cut -f 1 -d ” ” | grep -v Module | xargs > /tmp/modules.loaded
rmmod `cat /tmp/modules.loaded`
[/sourcecode]
and after resume it must do:
[sourcecode language=”java”]
for module in `cat /tmp/modules.loaded`
do
modprobe $module
done
[/sourcecode]
In gentoo you must install app-laptop/powerprefs and use my /etc/power/event.d/modules file.
CPU Variable Speed
To make you iBook a less battery user, you can alter automagically the cpu freq in order to use only the calculation power you need. So, when you use all the cpu, it works at the 100% of his speed, but when you don’t use it the cpu runs slower to get colder.
I’ve used speedfreq:
[sourcecode language=”java”]
emerge speedfreq
rc-update add speedfreqd default
[/sourcecode]
Fan speed
To get a better control of your iBook G4 temperature and fan speed, you can use the module therm_adt746x.
[sourcecode language=”java”]
modprobe therm_adt746x
[/sourcecode]
or put the module into your /etc/modules.autoload file
Modules
The module I use and I load at startup are written into a file called /etc/modules.autoload.d/kernel-2.6:
modules.autoload ( My /etc/modules.autoload.d/kernel-2.6 )
[sourcecode language=”java”] sungem
airport
ohci_hcd #usb 1
ehci_hcd #usb 2
ohci1394 #firewire
usb_storage #mp3 mplayer and Sony digital camera
snd-powermac #for sound
snd-pcm-oss #for sound
usb-serial #for GPRS using my sony ericsson phone
visor # for palm m125
#apm_emu #emulate APM (power management)
therm_adt746 #fan control (I use fan_speed=128)
uinput #for mouseemu
uninorth-agp #for DRI (agpgart will come with it)
radeon #for DRI 3D video acceleration
therm_adt746x # to control fan speed and temp
[/sourcecode]
Sound
You can configure the sound card with alsa modules and either using a sound daemon (i.e. arts), or by using oss emulation output. You can insert arts in USE flags, as I do.
Mac On Linux
Mol runs correctly on my iBook, with networking enabled.
It’s necessary to add this use flag:
USE=”fbcon”
before emerging //MOL//.
Run
[sourcecode language=”java”]
molvconfig
[/sourcecode]
and now edit
/etc/mol/molrc.video
to get fullscreen with MOL. Now you have linux on CTRL+ALT+F7 an MacOSX on CTRL+ALT+F8
I use an external ADSL eth0 router with dhcp, so I’ve used tun.ko kernel module and this configuration for mol:
/etc/mol/molrc.net
I use the internal dhcp so in MOL I don’t have to specify an address.
hdparm
I use this settings for hdparm, to increase hard disk performances and decrease the hdd temperature:
[sourcecode language=”java”]
hdparm -S 1 -d1 -m16 -c1 -X udma5 /dev/hda
[/sourcecode]
Make sure to load this settings on every boot.
Time config
Since I have also MacOSX, I had a problem with my clock settings. The hardware clock is set to UTC time by MacOSX, and my Linux system on everyboot read the time from the hardware clock, thinking this is set against my local time (Europe/Rome, CEST).
To solve this problem, you must tell hwclock to use –utc when used to update your system time.
In a RedHat/Fedora system is really simple, once known the origin of the problem:
Simply write this few lines into /etc/sysconfig/clock
[sourcecode language=”java”]
ZONE=”Europe/Rome”
UTC=true
ARC=false
[/sourcecode]
Airport Extreme Wireless Driver
It seems (http://bcm43xx.berlios.de) someone has written a driver for the Broadcom 43xx wireless chip, the one inside AirPort Extreme included into our iBook G4. It needs 2.6.14 kernel, and I’ve uploaded my config file for the 2.6.14-rc4 (the latest 2.6.14 branch I’ve found at this time).
Now you must get the firmware of your driver. Let /media/macosx be the MacOSX partition mount point. then you must use the fwcutter utility in the package:
[sourcecode language=”java”]
./fwcutter /media/macosx/System/Library/Extensions/AppleAirPort2.kext/Contents/MacOS/AppleAirPort2
[/sourcecode]
and then copy the *.fw files on
[sourcecode language=”java”]
cp *.fw /lib/firmware/
[/sourcecode]
If you want, I’ve made a copy of the driver you can download:
broadcom43xx.tar.bz2
I loaded the bcm430x driver correctly, but I don’t have a wireless access point here, so I cannot try if it works.

Thanks to Harddrake for those informations :) ( you can download it at http://www.linux-mandrake.com/harddrake∞ )
Update (27-5-2002): I’ve corrected the Mouse cursor problem with Linux in a Compaq Presario
Sometimes, when the memory is full and linux swaps on hard drive, the mouse cursor leave his correct position and the mouse clicks 1 cm left from the pointer. To correct that problem, insert the line Option “sw_cursor” in the Section “Device” of /etc/X11/XF68Config-4 configuration file. That corrects the problem. I’ve updated the configuration files.
Update: Now also the Conexant winmodem works correctly!
Thanks to Mark Hopkins for this wimodem help
You can find a driver at the location:
http://www.mbsi.ca/hsflinux/
I’ve tested it with Red Hat 7.2, and it works correctly. Because I don’t live on US, after the installation with the rpm of the driver I’ve launched that command:
# hsfconfig –country
And then Selected “Italy”. You can select here your different country.
See those urls to get more information:
http://www.linmodems.org
http://www.geocities.com/SiliconValley/3217/Documents/WinModems.html
http://www.o2.net/~gromitkc/winmodem.html
http://walbran.org/sean/linux/linmodem-howto.html
I’ve installed a Mandrake 7.2 , a Red Hat 7.1 and a Red Hat 7.2 distribution. They don’t recognize our graphic card, but the only thing you have to do is to replace the /etc/X11/XF86Config or /etc/X11/XF86Config-4 with the one provided in this page. (Read the files table). I use the touchpad or an external ps2 mouse, there’s no problem with the configuration.
If you want to use an external ps2 wheel mouse you must disable the gpm daemon on console, because it makes the mouse on console crazy and flipping. If you want to use the wheel, you must edit the section “imputdevice” as follow
Section “InputDevice”
Identifier “Mouse0”
# Modified by mouseconfig
Driver “mouse”
Option “Device” “/dev/mouse”
Option “Protocol” “IMPS/2”
Option “Emulate3Buttons” “no”
Option “ZAxisMapping” “4 5”
EndSection
This notebook has a confortable little display that shows the battery status, so I have not installed any dock to show the apm status in my desktop. Just run “apm” on a console if you want the % of charge.
And here is my configuration files:
Kernel Configuration (version 2.2.4-test11).
The soundcard works with the Via kernel driver, just do a modprobe to load the modules (Red Hat 7.2 does it automatically): .config
Xfree Configuration (for version 3.3.6)
It’s with italian keyboard, so if you want an other country map just modify the keyboard section and substitute the “it” with your keymap.
I used there 8 Mb for the videoram, setted from the bios. To use the mtrr acceleration, execute this command (after recompiling the kernel, with my .config file or with mtrr enabled):
echo “base=0xF5000000 size=8192k type=write-combining” >/proc/mtrr
XF86Config
Xfree Configuration (for version 4.*) (NEW)
The only way to make the new Xfree working with our laptop is to change first the /etc/lilo.conf file, adding a line with the VGA mode. If not, launching the Xfree server you will get working section of video, but not centered and moved on the right (if you can correct this error, send the solution to me). So change the lilo.conf file like this:
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
vga=791 <-------- That line is fundamental
lba32
prompt
timeout=30
message=/boot/message
default=Windows
image=/boot/vmlinuz-2.4.2-2
label=linux
read-only
root=/dev/hda7
append="ide=ata66 idebus=66"
vga=788 <--------# That line is fundamental
image=/boot/vmlinuz-2.4.2-2 <----- this section is the same
# that above, but without the vga line. Add it to be
#sure when you will
#reboot to have at least one lilo image working.
label=linuxtext
read-only
root=/dev/hda7
append="idebus=66 ide0=ata66 ide0=dma hda=autotune ide0=autotune"
other=/dev/hda1 <--- this is not fundamental :)
optional
label=Windows
Then you must be sure to use the Xfree 4 version. In modern distribution (like Mandrake 7.2, 8, Red Hat 7.1 and so on) you have the choice at the installation time. After that, you can change the Xfree version running on your machine by changing the /etc/X11/X simbolic link. If it brings to /usr/bin/X11/XFree86 then you're using the 4.* version. If it link to a /usr/bin/X11/XF86_* then you're using the 3.3.6 one. Just change that link to the one you want!!
So now you can put my configuration file XF86Config-4 in your /etc/X11 dir.
It's with italian keyboard, so if you want an other country map just modify the keyboard section and substitute the "it" with your keymap.
I used there 4 Mb for the videoram, setted from the bios. To use the mtrr acceleration, se the relative documentation in the kernel source tree.

Clima: Matteoli, Accordo di Kyoto non basta, fare di più
E fin qui siamo tutti d’accordo. Certo che se almeno venisse ratificato questo protocollo da parte degli Stati Uniti, che impone solamente una riduzione del 6% delle emissioni e che quindi è inadeguato ed insufficiente (ma è sempre un primo passo), allora potrebbe partire almeno questo progetto.
Ricordo che il protocollo di Kyoto per andare in porto dev’essere ratificato da un insieme di paesi che coprano almeno il 55% delle emissioni attuali, e che Stati Uniti e Russia non hanno ancora accettato (se uno qualsiasi dei due firmasse, il progetto potrebbe partire).
Quindi la notizia del progetto portato avanti dal nostro ministro dell’ambiente mi può stare anche bene, ma prima di pensare a nuovi finanziamenti si potrebbe cercare un accordo per portare a termine quelli precedenti.
Oltre a questo problema, bisognerà vedere su quali ambiti andranno a finire i finanziamenti di 30 milioni di euro previsti per questo progetto a due mani, e mi piacerebbe sapere perché Italia e Stati Uniti prendano strade diverse da quelle degli accordi internazionali già stabiliti ed in itinere per portare avanti le soluzioni ambientali.
Ecco la notizia Ansa:
(ANSA) – SACRAMENTO (CALIFORNIA) – Il protocollo di Kyoto non basta piu’. Per proteggere il clima ”diventa indispensabile definire una strategia e attuare misure con orizzonti ed effetti molto piu’ significativi di quelli definiti dal Protocollo” A lanciare una nuova sfida anti-emissioni nocive e’ il ministro dell’ambiente Altero Matteoli giunto a Sacramento in California per firmare un accordo di partnership con il governo statunitense in funzione della ricerca e dell’attuazione di nuove tecnologie per affrontare i cambiamenti climatici. Un accordo che si inserisce nell’ambito della due giorni di workshop che mettera’ a confronto le aziende statunitesni e italiane e che si e’ aperto oggi nella citta’ californiana. Se venisse confermato il trend attuale, entro il 2030 la domanda di energia aumentera’ piu’ del 50% e le relative emissioni di Co2 cresceranno piu’ del 60% rispetto ai livelli attuali a causa dell’incremento degli usi energetici dei combustibili fossili soprattutto nelle economie emergenti di Cina, India e altri Paesi in via di sviluppo con rischi per gli equilibri climatici. Proprio ”per garantire la stabilizzazione della concentrazione di Co2 a livelli di sicurezza entro la fine del secolo – ha detto Matteoli – gli scenari internazionali prevedono che sara’ necessario avviare, in un periodo compreso tra il 2020 e il 2050, una riduzione globale delle emissioni pari ad almeno il 50-60 per cento rispetto ai livelli del ’90”. Una percentuale che supera di gran lunga l’attuale 5,2% previsto dal protocollo di Kyoto solo per i Paesi maggiormente sviluppati. Ecco perche’, secondo il ministro, ”a cominciare dal 2020 la risposta alla domanda di energia dovra’ essere basata anche su un impiego sempre piu’ diffuso delle fonti rinnovabili, delle tecnologie collegate all’utilizzo dell’idrogeno e delle celle a combustibile, delle tecnologie ‘pulite’ e ad alta efficienza per l’impiego dei combustibili fossili e delle tecnologie per la ‘sequestration’ del carbonio”. In particolare, secondo il piano del ministero dell’ambiente, saranno necessari uno sforzo straordinario di ricerca e innovazione nel senso, ha spiegato Matteoli ”di un vero e proprio shock” tecnologico per rendere economicamente conveniente l’utilizzo di nuove fonti energetiche ‘pulite’ e sicure e, contemporaneamente, favorire la diversificazione dell’offerta rispetto ai combustibili fossili”. Accanto a questo, indispensabile un impegno generalizzato di tutti i Paesi, sviluppati e in via di sviluppo, al fine di ridurre le emissioni e giungere a una stabilizzazione della concentrazione di anidride carbonica in atmosfera. Terreno comune di questa sfida e’ la Convenzione quadro sui cambiamenti climatici sottoscritta a Rio ’92 che gli Usa ”non hanno mai rinnegato”, sottolinea il ministro Matteoli. Convenzione e ‘ponte’ della cooperazione tecnologica costituiscono in sostanza la base per costruire ”un nuovo partenariato tra Unione Europea e Usa sui cambiamenti climatici”. In tal senso il programma di cooperazione tecnologica e scientifica Italia-Usa rappresenta il primo mattone di questo nuovo impegno internazionale che non e’ alternativo a Kyoto ma va oltre quel protocollo. ”Questa riunione bilaterale – ha spiegato Matteoli – rappresenta in modo concreto la volonta’ dell’Italia e degli Usa di dare attuazione alla visione comune dei presidenti Bush e Berlusconi contenuta nella dichiarazione del luglio 2001, che impegna i nostri due Paesi a lavorare insieme sia per rafforzare la ricerca sui cambiamenti climatici sia per sviluppare tecnologie a basse emissioni”. A rispondere a queste esigenze diverse aziende italiane sbarcate in California per confrontarsi con i partner statunitensi. Cattura di Co2, celle a combustibile e micro turbine, produzione di idrogeno energie rinnovabili ed efficienza energetica i macro-argomenti sui quali verte il workshop di Sacramento al quale porteranno il loro contributo tra gli altri, Eni, Enel, Fiat, Enea, Politecnico di Milano, Ansaldo, Solvay. Ma per lanciare questa iniziativa globale Governi-imprese, e’ necessario, ha spiegato Corrado Clini, direttore generale del ministero dell’Ambiente e responsabile tecnico dei negoziati con gli Usa, garantire un sistema in grado di dare priorita- ai finanziamenti sulla ricerca tecnologica; di realizzare un quadro di standard internazionali per codificare i vantaggi ambientali ed energetici delle diverse opzioni; riorientare i fondi per il sostegno di questi progetti; introdurre il ‘free-trade’, ovvero il libero commercio delle tecnologie energetiche. Il tutto secondo una prospettiva che abolisca la logica fondata su obblighi e sanzioni, il command and control, e invece abbia come punto di riferimento accordi commerciali comuni”. (ANSA). GU
