In case you did not know, Android 2.1, Éclair, runs on the 2.6.29 Linux kernel. However, the user space it is built atop Dalvik, a Google-designed custom JVM (Java virtual machine).
This is pretty interesting, when you think about it. The core of Android is the linux kernel, and the standard... (5 Replies)
one of the thing that I think is great in android is that it bring linux to the end user.
Until now linux was used mainly on servers, super computer and embedded device.
However now with the smartphone and tablets, many people that never heard about linux use it without nowing it.

Hi guys :)
I've just switched from 32 bit to a 64 bit Arch Linux and I've installed the android SDK but, I can't run the emulator because some lib is missing ( ia32-libs ), if anyone have resolved this problem in a non Debian based GNU/Linux Distro let me know. I've search the web for that lib but... (2 Replies)

Hi,
I have a n android phone and just rooted it. I access it using 'terminal Emulator'. I performed many basic linux-like commands in the terminal like rm,ls,df,reboot etc and they are working fine. But many of them are not like man <something>, clear,du etc.
Can any of you please help to... (20 Replies)
I am looking for a way to run on top of the Linux kernel of an Android device. I want to use the existing configured Linux beneath Android rather than put a new Linux distribution onto a device.

ppmtosixel(1) General Commands Manual ppmtosixel(1)NAME
ppmtosixel - convert a portable pixmap into DEC sixel format
SYNOPSIS
ppmtosixel [-raw] [-margin] [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces sixel commands (SIX) as output. The output is formatted for color printing, e.g. for a DEC
LJ250 color inkjet printer.
If RGB values from the PPM file do not have maxval=100, the RGB values are rescaled. A printer control header and a color assignment table
begin the SIX file. Image data is written in a compressed format by default. A printer control footer ends the image file.
OPTIONS -raw If specified, each pixel will be explicitly described in the image file. If -raw is not specified, output will default to com-
pressed format in which identical adjacent pixels are replaced by "repeat pixel" commands. A raw file is often an order of magni-
tude larger than a compressed file and prints much slower.
-margin
If -margin is not specified, the image will be start at the left margin (of the window, paper, or whatever). If -margin is speci-
fied, a 1.5 inch left margin will offset the image.
PRINTING
Generally, sixel files must reach the printer unfiltered. Use the lpr -x option or cat filename > /dev/tty0?.
BUGS
Upon rescaling, truncation of the least significant bits of RGB values may result in poor color conversion. If the original PPM maxval was
greater than 100, rescaling also reduces the image depth. While the actual RGB values from the ppm file are more or less retained, the
color palette of the LJ250 may not match the colors on your screen. This seems to be a printer limitation.
