Free to swap software for linux

The cryptoswap package supports building an encrypted swap partition when a system boots. This must be necessary on systems that use encrypted filesystems because plaintext secrets may be written to disk when memory is swapped to disk.
Cryptoswap.sh should be installed in /etc/init.d. During system boot, cryptoswap.sh should execute right before checkroot.sh. When shutting down, cryptoswap should execute after sysklogd.
This package also includes an initialization script for building loopback encrypted /tmp. This may be necessary if a system contains encrypted filesystems but / is not encrypted. A link from directories like /var/tmp to /tmp may be appropriate. There are a few other alternatives for systems such as these:
1. Tmpfs is a Linux kernel feature that allows /tmp to exist in memory. This is a good solution for systems with a lot of memory and/or (encrypted) swap.
2. If you have a system that uses encrypted home directories, per-user temporary directories inside $HOME could be used. This would ensure that users data is protected but would require that all applications use $HOME/tmp instead of /tmp.
Finally, the project may be used to create an encrypted root filesystem. Doing so requires two special partitions. First, create a small partition to hold your kernel and initrd image, /dev/hdaX. Second create a large partition to contain the root of your filesystem, /dev/hdaY.
Next configure and install an initrd-based boot system:
1. Ensure romfs is compiled in your kernel (not a module).
2. Create a kernel-supported filesystem on /dev/hdaX and copy your kernel to /vmlinux.
3. Download busybox and extract it as initrd/busybox.
4. Update initrd/src/etc/modules.initrd to include any modules needed to boot.
5. Build cryptoswaps initrd image (cd initrd && make initrd) and copy it to the filesystem on /dev/hdaX at /initrd.img.gz.
6. Make sure you use literal = "root=/dev/ram0 init=/linuxrc rw" or LILO equivalent.
Finally, create a proper encrypted filesystem on /dev/hdaY:
1. Randomize the partition: dd if=/dev/urandom of=/dev/hdaY.
2. Set up a loopback device: openssl enc -d -aes-256-ecb -in initrd/src/etc/efsk | losetup -p0 -e aes /dev/loop0 /dev/hdaY.
3. Create the root filesystem: mkfs.ext2 /dev/loop0.
4. Mount your new root filesystem: mount /dev/loop0 .
5. Populate your new root filesystem.
Enhancements:
- Added initrd build environment.
- Documentation update.

CookieSwap provides an extension that enables you to maintain numerous sets or profiles of cookies that you can quickly.
Main features:
- Changing your cookies/identity to web e-mail sites (like Yahoo, Gmail, Hotmail, etc) so that you can quickly look like different users. Nice if you maintain multiple accounts and are tired of logging out and then back in to switch accounts. Also nice if two people are using the same computer and want to switch between accounts quickly.
- Changing your cookies/identity to see how sites like Amazon and Google treat you differently depending on who you are. For example, if Amazon recognizes you as a returning shopper they give you a different looking page (and there were claims that they give you different prices also). Google has begun to use a feature called "Personalized Search", where they modify their search results based on your user identity. There is a question about this when you create your Google account. The results of Google searches are different depending on if Google knows you or not. Use CookieSwap to quickly swap between Google recognizing you and being anonymous. Run the same search and see the differences.
- If you design web sites, you can setup numerous cookie profiles to look like different types of users and swap between those users quickly and easily to test your site in numerous modes (you can hand edit the cookies to have distinct values in each profile using a nice extension like Add & Edit Cookies).

Atop project is an ASCII full-screen performance monitor, similar to the top command.
At regular intervals, it shows system-level activity related to the CPU, memory, swap, disks and network layers, and it shows for every active process the CPU utilization in system and user mode, the virtual and resident memory growth, priority, username, state, and exit code.
The process level activity is also shown for processes which finished during the last interval, to get a complete overview about the consumers of things such as CPU time.
Atop only shows the active system-resources and processes, and only shows the deviations since the previous interval.
Enhancements:
- A new command, atopsar, has been added to generate detailed system activity reports (similar to the UNIX command sar) using the compressed logfiles as written by atop.
- These reports can also be generated for the current situation by specifying an interval for atopsar on the command line.

tooLAME is an optimized Mpeg Audio 1/2 Layer 2 encoder.

It is based heavily on:

- the ISO dist10 code
- improvement to algorithms as part of the LAME project

Installation:

1. edit Makefile
at least change the architecture type (ARCH) to suit your machine.
2. make

Usage:

./toolame [options] < input > < output >

Input File
tooLAME parses AIFF and WAV files for file info
raw PCM is assumed if no header is found
for stdin use a -

Output File
file is automatically renamed from *.* to *.mp2
for stdout use a -

Input Options
-s [int]
if inputting raw PCM sound, you must specify the sample rate
default sample rate is 44.1khz.

-a
downmix from stereo to mono
if the incoming file is stereo, combine the audio into
a single channel

-x
force byte-swapping of the input. (current endian detection is dodgy,
so if toolame produces only noise, use -x )

-g
swap the LR channels of a stereo file

Output Options
-m [char]
the encoding mode (default j)
s stereo
d dual channel
j joint stereo
m mono

-p [int]
which psy model to use (default 1)
Different models for the psychoacoustics
Models: -1 to 4

-b [int]
the total bitrate
For 48/44.1/32kHz default = 192
For 24/22.05/16kHz default = 96

-v [int]
Switch on VBR mode.
The higher the number the better the quality.
Useful range -10 to 10.
See README.VBR for details.

Operation
-f
fast mode turns off calculation of the psychoacoustic model.
Instead a set of default values are assumed

-q [int]
quick mode calculates the psy model every num frames.

Misc
-d emp
de-emphasis (default n)
-c
mark as copyright
-o
mark as original
-e
add error protection
-r
force padding bits off
-D
add DAB extensions
-t [int]
talkativity setting. 0 = no message. 3 = too much information

Planetoids is a game similar to bejeweled. The player must swap jewels to create combinations, including power and hyper jewels.

It includes a top score board to keep track of high player scores. Planetoids game also includes a hint feature, various jewel types, custom board sizes, and more.

SystemXInfo is a Karamba theme, and requires superkaramba 0.37+. SystemXInfo displays:

- Kernel and KDE versions
- CPU Model + Clock (Mhz)
- CPU Performance Graph
- CPU & Case Temperature
- Ethernet Connection Statistcs
- WiFi Connection Statistics
- RAM & Swap Usage
- 3 Partitions Usage
- Uptime and Date

This is made for systems that have 1 Ethernet and 1 WiFi Connections enabled and running.

My Linux box is running SuSE 10.0 + KDE 3.5.1

For WiFi, replace "ra0" with your module name (ex. wlan0)

Under CPU INFO:

I got text "O/C @2700Mhz", as mine is. You can change the text to your o/c specs, or delete it ... as you wish.

To show CPU and Case temperatures use the correct config line to sensors result.

Also you can modify this script further to suit your system configurations.

Thanks to the creator of original Talv 0.1 applet, that was modified further by me.

btfs can be used as /init for constructing a run-time environment before running the real init.

The project supports extracting compressed (*.cgz, *.cbz2) and uncompressed (*.co) cpios located on a compile-defined directory (/).

Also, it creates a tmpfs filesystem as the new root, if / isnt one already and the purpose of the initramfs isnt for starting a system in another location (disk, network, etc.). That will allow for the data on / to be swapped to disk when swap devices are activated later.

Usage: install as /init on an initramfs.

Boot description:

1. if / isnt a tmpfs or a ramfs or the program isnt init (pid == 1), it refuses to run

2a. if / isnt a tmpfs:
i. mounts a tmpfs on an empty /newroot*;
ii. extracts all cpio files (*.co *.cgz *.cbz2) under ARCHIVE_DIR (/) to the tmpfs;
iii. moves all other files on / to the tmpfs;
iv. remounts /newroot as the root filesystem;
v. chroots;
2b. extracts all cpio files (*.co *.cgz *.cbz2) under ARCHIVE_DIR (/) to /;

3. opens /dev/console;

4a. if theres a root= argument to the kernel, and it isnt /dev/ram*, executes /sbin/boot_other as init (change with option boot_other=).
4b. executes /sbin/init (change with option init=).
