GNU Emacs 24.4 Released Today

marcello_dl Re:Sounds nice (151 comments)

Emacs is neatly packaged so you can install only the things you like, just as debian does for python, ruby, and lots other environments (emacs is more like them than a mere editor).

Because, I repeat, it is not cancer.

'Microsoft Lumia' Will Replace the Nokia Brand

marcello_dl Re:Not a very exciting name (144 comments)

And for the funny part:
Being a "sega" is slang for being inept in Italy, so when the arcade machines displayed a full screen "Sega" some time after game was over, it was an insult to the guy who just lost the game, and was taunted by his fellows with that word.

Having said that, they market everything under the Sega name and people don't care much anymore.

Debian's Systemd Adoption Inspires Threat of Fork

marcello_dl Re:That's all we need ... (533 comments)

Debian goals are incompatible with a systemd-only system, that's the reason.
Removing mandatory systemd dependencies is what debian has to do. The technical committee can choose systemd as default init system, but from there to only init system means they can all go home and install redhat.

They won't react badly unless emacs gets pulled as a dependency and renames network interfaces. Which it won't do because it is not cancer.

GNU Emacs 24.4 Released Today

marcello_dl Re:do one thing and do it well (151 comments)

vi is pretty much the best example to push in the face of systemd apologists.

vi is default in every distribution, nobody bats an eye.
systemd tries to do the same and everybody lose their mind.
The reason is simple. You don't have to deal with vi at all if you don't choose so. And if you really really do not like it...

# aptitude search vi | grep ^i ...
i vim-common
i vim-tiny ...

# aptitude purge vim-tiny vim-common
The following packages will be REMOVED:
    vim-common{p} vim-tiny{p}
0 packages upgraded, 0 newly installed, 2 to remove and 1 not upgraded.
Need to get 0 B of archives. After unpacking 1093 kB will be freed.

vi is not cancer.

Apple Doesn't Design For Yesterday

marcello_dl Re:They are all going down the toilet (368 comments)

Ubuntu Unity seems to be the only cool-looking UI left.

I can't say it's not cool looking. As long as all you have to do is look at it, you're set.

My 2c on the topic. Apple knows what to do, the objective is not to make the best looking hi res desktop, it is to make the lower res desktop look like sh1t. Marketing 101.

Debian Talks About Systemd Once Again

marcello_dl Re:Remove It (519 comments)

In a way, Red Hat cares about linux users. You see, when linux users have a distro working perfectly out of the box, RH's business model crumbles.

A systemd based, never fully defined, never fully complete Linux, is what RH Canonical and hardware makers need to do the desktop linux transition. Devs who jump on the train will do like devs on win and osx, always work to adapt the new versions to the changes and fuck the old versions and its users.

New users are even more fucked up because they might look up howtos on the web that have worked for more than a decade, until systemd and similar projects obsoleted them for no compelling reason.

Ask Slashdot: Stop PulseAudio From Changing Sound Settings?

marcello_dl Re:are the debian support forums down? (282 comments)

Have you tried using pulseaudio just for skype? like identifying which libraries gets used, put them in (folder), starting manually the pulseaudio daemon if there is one, and invoke skype from terminal prefixing it with LD_LIBRARY_PATH=(folder)?
Failing that, I had 32 bit skype in a chroot because the rest of the system was 64 it worked. One day it keep failing authorization, and then i got an email telling me i was using an outdated skype version. That must be the microsoft way.

Lockheed Claims Breakthrough On Fusion Energy Project

They use radial coordinates to calculate the space needed for a reactor, because you gotta be taking radiation into account, of course.

Confidence Shaken In Open Source Security Idealism

marcello_dl Re:I don't buy it (264 comments)

a couple of years after Oracle assumed control of MySQL, people left in droves. Why? Because when it was open source it was better maintained, security flaws were patched faster and more often, etc.

It is not the best example, one could object that MySQL was bought to be eventually snuffed.
On the other hand this highlights the very problem with non-free software. All considerations, including security, are secondary to the corporation's mission. So, there needs to be free software no matter what, else security will get worse.

as the user whose desktop you want to share:

$ vncserver

setup passwords, a screen number is issued, usually 1

on local:

# aptitude install xtightvncviewer

First install usb-modeswitch package (debian squeeze - that is, testing at the moment - has it)
Then make sure that the udev initialization is correct:
# Sony Ericsson MD400
#
# This is experimental. Might switch back after some time. Please report!
# This might work too instead; subject to testing
# Vendor:Product id = 0x0fce:0xd0e1
SUBSYSTEM=="usb", SYSFS{idVendor}=="0fce", SYSFS{idProduct}=="d0e1", RUN+="/usr/sbin/usb_modeswitch --default-vendor 0x0fce --default-product 0xd0e1 -O 1"

Then plug the modem in, make sure it doesn't show up as usb disk, then install wvdial.

A working configuration for italian isp wind is the following:

[Dialer Defaults]
Init1 = ATX3
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CFUN=6
Init4 = AT+CGDCONT=1,"ip","internet.wind"
Phone = *99#
Modem Type = USB Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyACM0
ISDN = 0
Password = wind
Username = wind

Line init4 must be adapted to your ISP.
It is important to have the init3 line which turns the radio on. 6 means use HSDPA only, other values might be require if you don't have cover or other subscription, but beware the cost and speed. Why does a modem that works only with radio signals need to explicitly turn on its radio is beyond me. Good luck.

First of all, aptitude-upgrading, the debian image still has the random number gen. vulnerability. I went for lenny so i have a recent git and postgresql 8.3

Did tzsetup, and aptitude installed locales
added a normal user

Linode configures with DHCP his servers. Might have advantages but i prefer a static one

iface eth0old inet dhcp

iface eth0 inet static
        address (...)
        netmask 255.255.255.0
        gateway (...)
        dns-nameservers 207.192.69.4 207.192.69.5

and put a name in /etc/hostname

Then installed arno-iptables-firewall.
Opened ports 80 443 (it's gonna be a server)
FULL_ACCESS_HOSTS="(my machine domain name)"
FIREWALL_LOG=/var/log/firewall
LOGLEVEL=debug

then
touch /var/log/firewall

in /etc/syslog.conf kern.* must be changed to kern.!=debug
and the following added:
      # Logging for iptables
      kern.=debug -/var/log/firewall

then /etc/init.d/sysklogd restart

and restart arno firewall

To prevent firewall messages on lish console out add to /etc/init.d/klogd:

KLOGD="-c 4"

And restart that one too.

Better use logrotate too, see
http://linuxgazette.net/114/keeling.html

in /etc/logrotate/logrotate.d /var/log/firewall {
                      rotate 7
                      daily
                      compress
                      notifempty
                      create 0640 root adm
                      delaycompress
                      create
}

and start logrotate to see if it kinda works /usr/sbin/logrotate /etc/logrotate.conf

Note, this procedure involves some downtime for the server.
First dump existing databases, e.g.

# su - postgres -c 'pg_dump -C my_database > /tmp/my_database.sql'

If you have user putting content into database this step could be done later, just before importing the sql in the new cluster. Remember to take down db clients if you care for db consistency.

Then install new version, e.g.

# aptitude install postgresql-8.3

when one installs a new version of postgres under debian, the old version stays installed and a new cluster is automatically created. The new version server is configured for an alternative port (5433). Watch for the messages/logs from the package manager.

Then import old users into the new cluster, take into account the listening port run the updated client as the bash command "psql" defaults to the old version.

# su - postgres
# createuser a_user --port 5433

Then copy or update the pg_hba.conf settings to the one in the new cluster in /etc/postgresql/8.3/main/pg_hba.conf

Do not forget to reload the settings.
# /etc/init.d/postgresql-8.3 reload

Then import the databases
# su - postgres
$ /usr/lib/postgresql/8.3/bin/psql --port 5433

Then configure the new server for the existing server port, e.g.
# /etc/init.d/postgresql-8.3 stop
edit /etc/postgresql/8.3/main/postgresql.conf:
    port=5432

Then stop the db clients (eg. it's downtime for my dynamic sites hosted with lighttpd), take down old db, take up new one, restart db clients /etc/init.d/lighttpd stop /etc/init.d/postgresql-8.2 stop /etc/init.d/postgresql-8.3 start
    netstat -nat /etc/init.d/lighttpd start

test the db clients (restart your browser for webapps to avoid using stale session data), if all is well we must remove old postgresql else at reboot it is restarted, conflicting with the newest server version.

Since the debian remove scripts assume the server is up we must take the old server back up- we need to configure the old server for an alternative port so both versions can be up at the same time, e.g.

edit /etc/postgresql/8.3/main/postgresql.conf:
    port=5434

# /etc/init.d/postgresql-8.2 start
# aptitude purge postgresql-8.2

This is all.
Note. It is better to upgrade incrementally than doing it say, from 8.1 to 8.3
There might be ways to reduce downtime, with WAL for example.

aptitude install 915resolution

As the logged in user, with the graphical desktop already running:
SKIP_CHECKS=yes compiz --replace

One can also install emerald and emerald-themes, possibly purging and reinstalling at every update.

Verify you have the modules (recent 2.6 kernel needed stock lenny works)
modprobe -v udf
modprobe -v pktcdvd

aptitude install udftools
put your cdrom device in /etc/default/udftools
e.g. dev/hdX /etc/init.d/udftools restart

cdrwtool -d /dev/hda -q for a cdrw
dvd+rw-format /dev/hdd
and mkudffs /dev/hdd for dvd+rw

mount -t udf -o noauto,noatime,sync,rw,users /dev/pktcdvd/0 /mnt/

Now root is able to write on device, adjust permissions.

A spare laptop with no working cdrom and seemingly unable to boot from usb... but with a realtek boot agent. So it's netboot time. Another option is using wuby and install ubuntu right on the ntfs partition along with windows, but then you're back to square one if something happens to the windows installation.

On a debian box used as server:
aptitude install tftpd-hpa dhcp3-server
if you have another dhcp server installed skip dhcp3-server but you have to find the proper config yourself.

edit /etc/default/tftpd-hpa

RUN_DAEMON="yes"
OPTIONS="-l -s /var/lib/tftpboot"

from your fave debian mirror in dists/etch/main/installer-i386/current/images/netboot/

downloaded netboot.tar.gz, expanded it in /var/lib/tftpboot

For /etc/dhcp3/dhcpd.conf let's assume the tftpd box is in 192.168.0.1, I have to specify "filename" and "next-server" options- all other options depend on your subnet:

subnet 192.168.0.0 netmask 255.255.255.0 {
    range 192.168.0.5 192.168.0.15;
        filename "pxelinux.0";
        next-server 192.168.0.1;
    option subnet-mask 255.255.255.0;
    option routers 192.168.0.1;
    option broadcast-address 192.168.0.255;
    option domain-name-servers [ put here DNS addresses, space separated];
}

Then restart the services to make changes effective /etc/init.d/tftpd-hpa restart /etc/init.d/dhcp3-server restart

Make sure machines on the subnet can freely access the net to download packages, else the installation won't be very straightforward.

On the box that needs the reinstall chose net boot (usually selectable in the bios and or among boot options menu).

If all goes well the debian boot installer prompt should appear. Only after installation is complete you can stop tftpd server.

BTW on the laptop HAL had to ignore the broken device: put this in /etc/hal/fdi/preprobe , as this blog entry says

<?xml version="1.0" encoding="UTF-8">
<deviceinfo version="0.2">
<device>
<match key="block.device" string="/dev/[DEVICE]">
<merge key="info.ignore" type="bool">true</merge>
</match>
</device>
</deviceinfo>

I already had the setup for 802.11b with my home lan

Note this setup is quite sub-optimal as the password is saved in plaintext
The wext driver is for recent 2.6 kernels, works for my ndiswrapper

add to /etc/network/interfaces:

iface wlan0 inet dhcp
                wpa-driver wext
                wpa-ssid "ZyXEL XXXYYY"
                wpa-psk [password plaintext]
# wpa-bssid 00:1a:2b:3c:4d:5e -> not necessary but likely safer
                wpa-key-mgmt WPA-PSK
                wpa-pairwise TKIP CCMP
                wpa-group TKIP CCMP
                wpa-proto WPA RSN

while git-svnimport can be used for proper subversion repositories, I had issues with it and a personal svn repository which didn't follow the traditional svn layout with trunk branches tags (shame on me). Well why not simply iterate over the revisions and importing them? Seems to work. Here's how I did it:

first run
svn info [URL of the svn repository you want to migrate]
to discover how many revisions it has till now.

then let's get the commit messages so we can recycle them:

for i in `seq 1 [number of revisions]`; do svn log -r $i [URL of svn repository] > /tmp/svnlog$i.txt; done

then:
svn co --revision 1 [path to the svn repository you want to migrate]
so that a dir with a working copy is created, we'll call it [target git repository]. Now let's migrate all changes:


cd [target git repository]/
git-init
echo *.svn >> .git/info/exclude
for i in `seq 1 [number of revisions]`; do cd .. ; svn co --revision=$i [URL of source svn repository] ; cd $OLDPWD ; git add . ; git-commit -a -F /tmp/svnlog$i.txt; done

That should do it. Better do a
git-gc --prune --aggressive
(Do it when nobody else is accessing the new git repository!!!) so that you save space on disk, and a
git clean -d
to get rid of now useless .svn dirs.

The cam (an old trust spycam 300) worked under ekiga or gqcam without problems, once the proper stv680 kernel module is installed.

for mplayer one must use the v4l driver specifying outfmt width and height, like this example

mplayer tv:// -tv driver=v4l:device=/dev/video1:outfmt=bgr24:width=320:height=240

Well the pic is upside down, can use -flip option or dunno turn the webcam upside down :)

"webcam" package is quite useful as a poor man cctv. here's a sample config

[ftp]
host = localhost
user = nobody
pass = xxxxxx
dir = /tmp
file = webcam.jpg
tmp = imageup.jpg
local = 1

[grab]
device = /dev/video1
width = 320
height = 240
delay = 1
wait= 1
norm = pal
quality = 75
trigger = 0

For complex stuff zoneminder.com ought to be the choice.

Nota: lascio libero chiunque di copiare modificare e riutilizzare il seguente articolo, che rilascio nel pubblico dominio. E' probabile che sul sito del produttore (www.empiremedia.it) si trovino ulteriori informazioni.

La usb pen mi funziona subito come analogico, dopo un po' funziona anche la parte digitale. Presumo sia una questione di caricare il firmware piu' adatto (v. sotto) o di aspettare che il driver maturi.

Per avere a disposizione la usb pen sotto linux bisogna compilarsi i moduli relativi. Quello disponibile con il kernel di etch non la riconosce.

Ho seguito le istruzioni in inglese su
http://www.marcushellberg.com/pages/projects/digital-tv-in-linux.php

Se non lo si sa, scoprire con
    uname -r
quale versione del kernel si sta usando, nel mio caso
    2.6.18-4-686

Usare questa informazione per scaricare la versione giusta degli headers:
    aptitude install mercurial linux-headers-2.6.18-4-686 build-essential

Fare copia di sicurezza dei moduli attualmente installati, casomai qualcosa andasse storto

    tar zcvf modulesbackup.tgz -C /lib/modules/ 2.6.18-4-686/

Scaricarsi e installare i moduli aggiornati usando mercurial

    mkdir dvbdriver
    cd dvbdriver/
    hg clone http://mcentral.de/hg/~mrec/v4l-dvb-kernel
    cd v4l-dvb-kernel/v4l/
    make
    sudo make install

Scaricarsi il firmware dal sito http://konstantin.filtschew.de/v4l-firmware/ (non va aggiornato il firmware della penna, va solo scaricato, viene usato dal modulo), a me va anche la versione 4, teoricamente andrebbe la versione 3.

una volta scaricato, scompattarlo in /lib/firmware, es:

    tar xvzf firmware_v4.tgz -C /lib/firmware/

a questo punto riavviare il PC inserendo la usb pen: i messaggi, ottenibili anche col comando dmsg, dovrebbero annunciare che la penna e' riconosciuta ed i moduli relativi caricati, ad esempio:

Si può regolare il volume con:

  alsamixer -c 1

premendo tab per scegliere l' input screen

A questo punto la scheda e' pronta, usando ad esempio mplayer, dopo aver verificato che mplayer funzioni con un file video (scelta del -vo adatto, verifica dei permessi per sentire l'audio ecc), per vedere la tv si usa

mplayer -vo xv tv:// -tv chanlist=italy:driver=v4l2:input=0:norm=2:device=/dev/video0:alsa=yes:audiorate=48000:amode=0:forceaudio=yes:adevice=hw.1,0:volume=80:immediatemode=0

(attenzione, inserire tutto su una riga e da chanlist= in poi senza spazi, in caso di dubbi vedersi l'help di mplayer- c'e' anche in italiano)

e usare h e k per provare tutti i canali fino a trovare qualche emittente.

Dopo qualche minuto di ricezione segnale analogico che a quanto pare sblocca la situazione, si puo' provare con il digitale. Consiglio di installare kaffeine, che ha una funzione di scansione canali. L'antennina in dotazione non ha fatto molto per me, collegando all'impianto antenna di casa (n.b. mai adattato al digitale terrestre) invece spuntano i canali, se la zona è servita.

Kaffeine permette di fare pausa del segnale video, registrarlo in mpeg2 (serve spazio su disco), e a quanto mi pare registrare un canale e vederne un'altro purche' appartenga allo stesso "stream".

Una stranezza, appena avviato kaffeine il segnale e' piu' debole, cambiando canale un po' la ricezione migliora. Ritengo sia qualche problema con i comandi dati al sintonizzatore.

Per la tv analogica riesco con mplayer a registrare in divx a 2000kbit e qualche filtro per incrementare la qualita' con un celeron a 1.7 giga. Registrando in mpeg2 o salvando direttamente lo stream (mai provato) si ha minor consumo di cpu e lievemente maggior qualità a scapito della dimensione del file.
