Booting Ubuntu To RAM is an article aims to document the process of creating a customized Ubuntu that loads an image from the hard disk to RAM, then boots an entire Ubuntu session out of RAM. It is intended for intermediate to advanced Ubuntu users who are familiar with the shell, and may have limited experience customizing the livecd (LiveCDCustomization) and shell scripting. We will customize a LiveCD and copy it to the hard drive, and make a few modifications to bootup scripts so that it copies to RAM via our good friend tmpfs.
WARNING: The author asserts that this procedure works for him, but cannot guarantee that this procedure works for anyone else. Although this procedure is meant to be 100% safe, it is feasible that there may be mistakes, or a chance of misunderstanding the instructions in a manner that causes loss of data. Please make a backup and do not attempt on mission critical systems. Read through this article thoroughly, and do not attempt if you do not comprehend or feel comfortable about any of the instructions!
CAUTION: I hope this is intuitively obvious, but Ill humor you and state it bluntly: Changes you make under the live session are NOT saved and WILL BE LOST when you reboot or shut down. Dont save anything important to the "home directory" and expect it to still be around! If you want to save data permanently, mount a permanent medium (such as your hard drive), plug in a thumbdrive, or use some network functionality built into Ubuntu to save your data to a non-volatile destination.
There are many cases where one would like to boot Ubuntu to RAM:
- Performance: The desktop performance is dramatically improved. A 400MB squashed filesystem in RAM, that holds 1200MB of data, is read back on a 1.6GHz Core Duo in about 3 seconds, including decompression time.
- Power, Noise, Durability: Although modern hard disks dont use much power compared to other system components, this may still be important for some. In laptops, hard disks are often the noisiest components, so this setup can reduce system noise. With the hard disk spun down, a laptop can potentially withstand greater shocks without damage.
- Abrupt poweroff: Since the hard disk is only momentarily used in read-only mode during boot, then never touched again, there are few or no negative consequences of an abrupt poweroff. If a system is used where power is inconsistent, or the system is regularly used in a context where fast shutoffs are required, this is very handy.
- Privacy: Anything you do in this session are lost when you reboot or power off. This is great for kiosks or other systems where permanent modification are not desired. (Note that by default the livecd user has full sudo access, so potentially a malicious user can still make permanent changes by mounting the hard drive and following this HOWTO)

Source Mage GNU/Linux distribution is based on a sorcerous metaphor of "casting" and "dispelling" packages, which we refer to as "spells".
This is a development ISO and potentially loaded with bugs and glitches. This is where you come in. We need your help to squash these bugs.
Please download, burn, and install this ISO to a spare partition, extra computer, or over your least favorite friends Windows partition. VMWare or bochs works too. Upon finding a glitch, please report it in bugzilla. No bug is too small, or too large.
Help shape the future of Source Mage! Download the Next Generation Testing ISO and install!
Enhancements:
- This is an updated release based on the 0.9.6 version of the ISOs.
- While it does not contain any changes in the actual installer scripts, it does have an updated set of packages/spells based on the 0.7 Stable Grimoire, including an updated version of the Linux kernel.

Heilan is a cross-platform OpenGL X3D browser written in C++ and designed for audio work. Specifically, it forms the environment within which I am developing an audiovisual instrument for my PhD. As such, it has a number of features not commonly found in X3D browsers:
Low latency audio courtesy of PortAudio (ASIO, DirectX, MME on Windows; Jack, ALSA, OSS on Linux; CoreAudio on OSX).
A 1st order B-format Ambisonic audio engine, allowing for full 3d sound, capable of accommodating virtually any speaker configuration (at the moment this is limited to preset configurations, but that will change in the future).
Open Sound Control support for all nodes, allowing a nodes attributes to be manipulated in realtime, potentially by multiple users.
A multi-threaded audio engine, able to split off different nodes audio processing into separate threads (and potentially, separate cpus/cores). This can be configured by the scene author.
Heilan aims to conform to the X3D Interchange profile, with additional support for certain nodes such as Sound and NurbsPatchSurface. It may be extended with libraries which can provide extra nodes, navigation types, and sound file loaders. It comes with a library containing my own experimental audiovisual nodes, and a couple of extra navigation types.
The browser itself is a command line program designed to be used offline (theres no browser plugin or http/ftp support), though there is a GUI frontend available as well (included in the binary package). Both are open source, licensed under the GPL.
Enhancements:
- This release has the EXAMINE navigation type implemented correctly for the first time, and multitexturing is now implemented.
- Basic support for GLSL shaders is also included via the ProgramShader and ShaderProgram X3D nodes.
- Some new nodes have been added to libheilanextras, and a number of minor bugs have been fixed.

Samhain is a multiplatform, open source solution for centralized file integrity checking / host-based intrusion detection on POSIX systems (Unix, Linux, Cygwin/Windows).
samhain project has been designed to monitor multiple hosts with potentially different operating systems from a central location, although it can also be used as standalone application on a single host.
Main features:
Centralized monitoring
- Samhain clients (or agents) can connect to a central log server via secure (encrypted and authenticated) TCP connections. This allows central logging to the server, central storage of baseline databases and client configuration data, and central updates of baseline databases.
Web-based management console
- For client/server installations, a web-based console - Beltane - is available as separate package. Beltane allows to monitor server and client activity, view client reports, and update the baseline databases on the server side.
Multiple logging facilities
- Samhain supports multiple logging facilities, each of which can be configured individually. Supported logging facilities include (but are not limited to) tamper-resistant logfile, syslog, email, relational databases (MySQL, PostgreSQL, Oracle, or unixODBC) and the Prelude IDS.
Tamper resistance
- Samhain offers PGP-signed database and configuration files, a stealth mode, and several more features to protect against attempts to subvert the integrity of the samhain client / agent.
Enhancements:
- This release fixes some minor bugs.
- The portcheck module tears down connections for some common protocols more gracefully.

Tresys Brickwall software makes it easy to manage the power of SELinux. Tresys Brickwall is built on an enhanced version of the Reference Policy that "targets" network facing applications for containment. SELinux forms a firewall around each application, protecting applications from each other and preventing an application from damaging the kernel. Tresys Brickwall provides an intuitive graphical user interface (GUI) that allows administrators to configure access to network resources at the application level. Security options (SELinux Booleans) can also be set on a per-application basis. Advanced users can even include raw SELinux policy for additional customization.

The Tresys Brickwall Professional and Enterprise Editions add targets for several applications not covered by the standard Reference Policy, and they allow administrators to define custom targets for applications not in the built-in target list. These editions also allow administrators to extend targets file access permissions.

The Tresys Brickwall Enterprise Edition adds a first-ever network management capability to SELinux. A central Tresys Enterprise Manager securely manages the configuration for all of the SELinux machines across an enterprise. Groups of client machines can be defined and a configuration can be managed and applied to all of the machines in that group. The Tresys Enterprise Manager also works with Tresys Razor™ products to manage enterprise applications like IBMs WebSphere and DB2.

xor-analyze provides a program for cryptanalyzing xor "encryption" with variable key length.
Main features:
- Could possibly crack bad implementations of one-time pads
- Check ftp://ftp.habets.pp.se/pub/synscan/ for windows binaries
To find out what length the password is the ciphertext is XOR-ed against itself with different shifts (see XOR_analyze::coincidence() in analyze.cc) and the number of zeroes (equal bytes) are counted. This is called counting coincidences. When the number of zeroes is high the shift value is potentially a multiple of the key length. The one that stands out most is checked with statistics (with a frequency table) to get the key. To check with statistics on all key-lengths in key-length interval (-m and -M) use the -a switch (with -v for one key per keylength)
Compiling
Type make. Mail me if it doesnt compile and dont forget to tell me what kind of system you have.
