We run a big share of Xen virtual servers spanned over multiple servers and if you want to use the full or best capability of Xen, I would suggest LVM (Logical Volume Manager), it makes life a lot easier, especially for those who do not run a RAID setup (We run RAID10 on all VM nodes) as you can split the partition over multiple hard drives. I’m not going to cover setting up the LVM as there are loads of tutorials on how to do that but I will rather cover the best way to migrate a LVM volume.
I have recently had reason to convert an Access MDB file to CSV for use in a mysql database. I don't like the idea of an Access database on a production server and Microsoft has been agreeing since 1999.
As it turns out it is actually very easy, there is GPL software available for the job at http://mdbtools.sourceforge.net/. If you are using Ubuntu or Debian you can use apt-get install the mdbtools package.
To get the list of tables, you run the following command:
mdb-tables database.mdb
You can then get a CSV version for each table using:
mdb-export database.mdb table_name
You can also convert the mdb into a format required by MySQL. First you must get the put the table schema into the database using the following command:
mdb-schema database.mdb | mysql -u username -p database_name
You then import each table by running:
mdb-export -I database.mdb table_name | sed -e 's/)$/)\;/' | mysql -u username -p database_name
Sed is required as mdb-export doesn't put a semi-colon at the end of each insert statement, which MySQL definately doesn't like.
After running this, you can now be rid of the horror that are Access MDB files :)
Dieser Artikel beschreibt, wie man das Energiemesssystem EM 1000 mit einem EM 1000-WZ Strommesssensor unter Debian einrichtet und die Messwerte mit Hilfe von Cacti darstellt.

Brain.exe schützt vor Viren wie kein anderes Programm: Für den integrierten Filter gibt es tägliche kostenlose Updates. Auch noch unbekannte Variationen kann Brain.exe filtern. Das Programm trennt Spam von richtigen Mails und erreicht dabei eine Trefferquote von 99,99%. Dieser Wert kann selbstverständlich nur erreicht werden, wenn man täglich die Software auf den neusten Stand bringt. Auch eine Firewall ist Brain.exe. Es verhindert, dass schädliche Programme installiert werden und Dinge ausspionieren, die lieber privat bleiben sollten.
OOoLatex is a set of macros designed to bring the power of LaTeX into OpenOffice. It contains two main modules: the first one, Equation, allows to insert LaTeX equations into Writer and Impress documents as png or emf images while the second one, Expand, can be used for simpler equations to expand LaTeX code into appropriated symbol characters and insert them as regular text.
The Sleuth Kit and Autopsy Browser. Both are open source digital investigation tools (a.k.a. digital forensic tools) that run on Unix systems (such as Linux, OS X, FreeBSD, OpenBSD, and Solaris). They can be used to analyze NTFS, FAT, Ext2, Ext3, UFS1, and UFS2 file systems and several volume system types.

This HOWTO describes how to configure Snort version 1.8.3 to be used in conjunction with the statistical tools ACID (Analysis Console for Intrusion Databases) and SnortSnarf. It also intends to get some internal statistics out of snort, e.g. if there are packets dropped.
This is an attempt to add support for the E3 chipset based scanners such as the Genius Vivid Pro USB scanner. In theory it should support the following scanners as they use the same chipset. Can you please let me know if your scanner is supported.
* Genius Vivid Pro USB
* Primax Colorado USB 19200
* Visioneer OneTouch 7600
* Visioneer OneTouch 6100
* IBM IdeaScan 2000 USB
* LG Electronics Scanworks 600U
This site is the home for the libusb project. It's aim is to create a library for use by user level applications to access USB devices regardless of OS.
PhotoRec is file data recovery software designed to recover lost files including video, documents and archives from Hard Disks and CDRom and lost pictures (thus, its 'Photo Recovery' name) from digital camera memory. PhotoRec ignores the filesystem and goes after the underlying data, so it will still work even if your media's filesystem has been severely damaged or re-formatted.
TestDisk ist ein leistungsstarkes freies Daten-Wiederherstellungs-Utility! Es wurde in erster Linie erstellt um verlorene Partitionen wiederherzustellen und/oder nicht bootende Festplatten wieder bootfähig zu machen, wenn das Problem durch fehlerhafte Software, bestimmte Arten von Viren oder menschliche Fehler (wie versehentliches Löschen der Partitionstabelle) verursacht wird. Partitionstabellen wiederherstellen mit TestDisk ist wirklich einfach.
Are you sick of audio players that think they know how to organize your music for you? Do other media libraries choke and die after a mere 10,000 songs? Do you often find yourself thinking Boy, I wish I could just grep my music? Or are you just looking for something that can tag your audio files?
