Darik's Boot and Nuke ("DBAN") is a self-contained [Linux-based] boot disk that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.

Dstat: Versatile resource statistics tool Dstat is a versatile replacement for vmstat, iostat, netstat and ifstat. Dstat overcomes some of their limitations and adds some extra features, more counters and flexibility. Dstat is handy for monitoring systems during performance tuning tests, benchmarks or troubleshooting. Dstat allows you to view all of your system resources in real-time, you can eg. compare disk utilization in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval)

SD4L is a suite of Linux tools and a graphical user interface (GUI) which allow the creation of, and access to ScramDisk encrypted container files. In particular, SD4L provides a Linux driver which enables mounting ScramDisk containers. ScramDisk for Linux also encrypts partitions on a hard disk or storage media such as USB sticks or floppy disks entirely as devices. Version 2.0, moreover, opens and creates TrueCrypt containers from TrueCrypt version 4.1 to 6.1a.

netboot.me is a service that allows you to boot nearly any operating system or utility on any computer with a wired internet connection - without having to know ahead of time what you'll want to boot. Once you can netboot.me, you never need to update your boot disk again! In order for your computer to know where to find the netboot servers, you need to change your DHCP settings to return some extra information. The two relevant pieces of information: next-server, which should be "tftp.netboot.me", and "filename", which should be "netbootme.kpxe". How to set these settings depends on your DHCP server. For dhcpd, simply add the following to the relevant 'subnet' section of your configuration: next-server "tftp.netboot.me" filename "netbootme.kpxe" For dnsmasq, the following line in /etc/dnsmasq.conf will achieve the same effect: dhcp-boot=netbootme.kpxe,tftp.netboot.me netboot.me works through the magic of netbooting. There are a number of ways to boot a computer with netboot.me. The simplest is to download a bootable image and burn it to a CD, USB memory stick, or floppy disk. Boot off it on any networked computer, and it will automatically fetch the latest boot options from netboot.me and let you choose from dozens of installation, recovery, testing, portable desktop and other tools. You can also start netboot.me from any computer running gPXE, or from any netbootable computer with some simple tweaks to your DHCP server.

The disk's ITR rating and internal cache size can be critical when tuning maxcontig (maximum contiguous I/O size). Note: maxphys and maxcontig must be tuned at the same time. The unit of measurement for maxphys is bytes; maxcontig is in blocks. maxcontig can be changed via the mkfs, newfs or tunefs commands.

We both know that all of the current Linux distribution can automatically mount all of the external hard drive such as usb flash drives, CDROM, usb disk and so on.... However, another bsd systems ware still necessary to manually mount all of the device no matter FreeBSD or openBSD, but in fact there is a way to let you mount external devices automatically when you insert a flash drive in your FreeBSD system...

fix 4TB hard disk driver that cannot be formatted in Ubuntu 12.04 config GPT in Linux via terminal

The release 3.0 of Spring Framework added the Spring Module OXM which supports the marshalling and unmarshalling of Java objects and XML documents.In this post, we will be using Spring OXM to take a Java object, convert it to a XML-format and save it in the hard-disk as an XML file containing information of that Java object. We will also cover how to retrieve back the serialized state of that XML file and reconstruct it back to it's original state as a Java object.

Nice tips for doing small backups with rsync

Fascinating discussion over at Stack Overflow. Elucidates some of the subtle differences between dd and cat, and when and why you might want to use one over the other.

The cdcat is graphical (QT based) multiplatform (Linux/Windows/MacOS) catalog program which scans the directories/drives you want and memoryze the filesystem (including the tags of mp3's) and store it in a small file. Features: - Searching with regex or wildcards in file names/comments/tags/etc... - Read mp3 tags (if you enable it) - Autoload database on startup - Can mount/umount/eject the cd-drive on Linux - Read file content from the specified files (e.g: *.nfo) - Platform indepentent Gzipped XML format. - Import/Export functions for CSV/XML-gtktalog/HTML - Possibility to add comment for files or directories.
