			<content:encoded><![CDATA[<p>After several years some voicebox messages of a Vbox system I&#8217;m responsible for had to be changed. Although I left a README file in the MSG directory with the commands used in the past to convert WAV to ULAW, the result wasn&#8217;t what I expected. There was an ugly cracking sound at the beginning of each ULAW file. As it wasn&#8217;t there in the intermediate AU files, it must be autovbox &#8220;adding&#8221; it. </p>
<p>After some research it turned out, that it is easily possible to convert WAV to ULAW in directly using SOX. The following command works like charm:</p>
<p><code>find . -name \*.wav -exec sox -V {} -r 8000 -c 1 -t ul -w {}.ulaw \;</code></p>

			<content:encoded><![CDATA[<p>Today I debugged a Bacula backup issue at of the networks I support during spare time. Every backup terminated with an &#8220;i/o error reading loaded0 file on magazine in bay 1&#8243; error after the first virtual volume was full and a new one should be loaded. I quickly figured out that upon mounting, the loaded0 file was still empty and therefore every unmount request as well as new mount requests just fails.</p>
<p>In order to see what exactly is going on when vchanger tries to load a volume, I ran:</p>
<p><code><br />
strace -f vchanger /etc/bacula/vchanger.conf -u bacula -g disk load 8 usbchanger1 0<br />
</code></p>
<p>You&#8217;ll never guess what the problem was! I forgot to set the number of reserved blocks to zero when preparing the file system of the disks, so from a normal users perspective the disk was just out of space.</p>
<p>Here you can see the important lines of the strace call:<br />
<code>open("/mnt/vchanger/donnerstag/loaded0", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 5<br />
fstat64(5, {st_mode=S_IFREG|0644, st_size=0, ...}) = 0<br />
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0xb77c2000<br />
write(5, "usbchanger1_0004_0008\n"..., 22) = -1 ENOSPC (No space left on device)<br />
close(5) = 0</code></p>
<p>A <code>tune2fs -m 0 /dev/sdc1</code> solved the problem, but why isn&#8217;t vchanger&#8217;s first load failing with an error message that tells me that it was not possible to update the loaded0 file? I think I am going to write a patch for this now.</p>
<p><strong>UPDATE:</strong> Here is my patch to correctly interrupt loading and write useful log information: <a href='http://www.tuxevara.de/wp-content/uploads/2012/01/diskmanager.patch'>diskmanager.patch</a></p>

			<content:encoded><![CDATA[<p>Oder anders gesagt: Wo Schatten ist muss auch irgendwo Licht sein.<br />
Ich hab ja seit knapp einem Monat ein Samsung Galaxy Tab 10.1N mit 3G &#038; WIFI. Bzgl. einer zweiten SIM-Karte zur reinen Datennutzung mit dem Tab hatte ich vor drei Wochen bei der Telekom nachgefragt. Der Mitarbeiter an der Hotline hat mir nach mehrfachem Nachfragen versichert, dass bei Multi-SIM SMS/MMS und Datenverbindungen immer nur auf einem Geraet aktiv sein koennen. Fuer SMS/MMS kann ich das im Prinzip noch nachvollziehen, fuer Datenverbindungen eher weniger.<br />
Vor ein paar Tagen bekam ich einen Tipp, mal in einen Telekom-Shop zu gehen und dort anzufragen. Das habe ich heute getan (Im Rheinparkcenter Neuss) und siehe da: Kompetente Mitarbeiterin! Nach knapp 10 Minuten bin ich mit weitere SIM-Karte aus dem Laden raus und die Aktivierungs-SMS hatte ich auch schon bekommen bevor ich den Laden verlassen habe. Gleich zu Hause ausprobiert und siehe da: Geht doch!</p>
<p>Im uebrigen hat mich das Datenschutzsystem auch ueberzeugt. Um irgendwas bzgl. eines bestehenden Vertrags zu besprechen oder zu aendern, muss man dem Mitarbeiter die eigene Mobilfunknummer mitteilen. Darauf hin bekommt man einen Sicherheitscode per SMS geschickt. Diesen nennt man dem Mitarbeiter und erst dann hat er Zugriff auf die Vertragsdaten. Sicherheitshalber ist auch noch der Name abgefragt worden. Ich denke das ist vorbildlich.</p>

Wenn diese voellig unnoetige Praxis auf unglaublich unfaehige Richter in unserem voellig maroden und veralteten Rechtssystem trifft, ist das Ergebnis, dass in Deutschland<a href="http://www.spiegel.de/netzwelt/web/0,1518,804629,00.html" target="_blank"> ahnungslose Rentnerinnen zur Zahlung von Abmahnungen verurteilt werden</a>. Und jeder der mal Einblicke in die ISP Netzte und damit verbundenen Systeme und Logfiles hatte, weiss wie schnell dabei Fehler gemacht werden. In den USA ist doch vor ein paar Jahren auch mal von einem Sondereinsatzkommando ein Bauernhof gestuermt worden, weil bei einem ISP jemand die Zeitzone nicht beruecksichtigt hatte. Also, fang endlich an den Grundsatz der Datenvermeidung umzusetzen. </p>

			<content:encoded><![CDATA[<p>Apple seems to be successful in fighting Samsungs Galaxy Tab 10.1 here in Germany. Asked for the (especially for Germany) resigned version of the Samsungs Galaxy Tab 10.1N at a Saturn shop (German chain of electronic device selling shops) and after a phone call to an other department I was told that they refuse to order that device even on customer demand due to Apples restraining order. Although the judgement will be given on December 22nd they seem to fear, not being allowed to sell the modified version in Germany also.</p>
<p>I had a glimpse at a Motorola&#8217;s Xoom tablet and am really asking myself why Apple does not jerk Motorola to court for the Xoom tablet too. It also looks exactly like the design patent of <del datetime="2011-12-02T22:00:40+00:00">Apple&#8217;s iPad</del>any $TABLET_PC.</p>
<p><a href="http://www.droid-life.com/2011/09/14/fridge-vs-apples-ipad-banned/">Fridge vs. Apple&#8217;s iPad</a> seems to become true if our judges don&#8217;t start using their brains very soon. Ever asked yourselves how all the television manufacturers can survive if the devices look so similar!?</p>
<p>Finally I&#8217;ve got only two words for you, Apple: FUCK YOU!<br />
You can be sure I&#8217;ll never buy or use one of your devices.</p>
<p><strong>EDIT:</strong> One day later I bought my 10.1N at a nearby Media Markt store. Although both stores belong to the same group, they seem to deal differently with the Galaxy Tab issue. So I now own a 10.N for more than two weeks and haven&#8217;t regret it yet.   </p>
