Whonix is an anonymous general-purpose operating system based on Virtual Box, Debian GNU/Linux, and Tor. By design, IP and DNS leaks are impossible. Not even malware with root rights can find out the user's real IP/location, because Whonix consists of two (virtual) machines. One machine solely runs Tor and acts as a gateway, called Whonix-Gateway. The other machine, Whonix-Workstation, is on a completely isolated network. Only connections through Tor are possible.
SHOGUN is a machine learning toolbox whose focus is on large scale kernel methods and especially on Support Vector Machines (SVM). It provides a generic SVM object interfacing to several different SVM implementations, all making use of the same underlying, efficient kernel implementations. Apart from SVMs and regression, SHOGUN also features a number of linear methods like Linear Discriminant Analysis (LDA), Linear Programming Machine (LPM), (Kernel) Perceptrons, and algorithms to train hidden Markov models. SHOGUN can be used from within C++, Matlab, R, Octave, and Python.
Super Grub2 Disk is a bootable floppy, CDROM, or USB system which lets you boot into your system. It is simply a Grub2 disk with a lot of useful menus. It can try to autodetect all of your operating systems, load your grub.cfg configuration file, and load grub2's core.img, even if the mbr is damaged. It has multi-language support.
Loadbars is a small script that can be used to observe CPU loads of several remote servers at once in real time. It connects with SSH (using SSH public/private key auth) to several servers at once and vizualizes all server CPUs and memory statistics right next each other (either summarized or each core separately). Loadbars is not a tool for collecting CPU loads and drawing graphs for later analysis. However, since such tools require a significant amount of time before producing results, Loadbars lets you observe the current state immediately. Loadbars does not remember or record any load information. It just shows the current CPU usages like top or vmstat does.
Vbackup is a modular backup utility that can be used to perform full or incremental system backups. It consists of a set of scripts that can be used to create backups using tar and xfsdump. It can also make backups of PostgreSQL, MySQL, and LDAP databases, keep a copy of the boot record, the partition table, or the LVM configuration, encrypt archives using x509 certificates, and back up the Debian package list and the RPM database. It can store the backups in a local or remote directory using either NFS or SCP. It is modular, and can be extended to perform other functions as well.
If you can't reconnect to your WiFi until you reboot your Froyo device, Wifix (lite) will probably help you. Just click the "Reassign" button, and about 8 seconds later you will be reconnected to your WiFi. You can use "Reconnect" if it doesn't work for you. There is also a "Keep Connection" checkbox that prevents your WiFi connection from been deactivated.
QMentat helps you practice mental arithmetic. It uses arbitrary-length fixed point arithmetic, and can handle any size numbers, only limited by the size of your screen (and in the case of division with an integer result, the speed at which the number can be factored). It is also quite configurable, allowing you to tailor the questions to your needs.
