I work in a computer company which sells computer configurations and parts of them. And I want to give a choice to customers. If they want to buy a PC with Linux installed, not Windows.

Windows blows. I'm poor so unix is looking like a great alterative (expecially after my former roommate showed me most of the things it can do). Right now I'm looking at Debian or some other Unix kernel that would run nicley on my computer.
But the problem we had with installing it while he was... (3 Replies)

Hi,
I have a simulation program which creates two threads and I would like to know if I can measure the time of each individual thread. Threads communicate (I use pthread to manage them) and I want to measure communication time. I found a solution with clock_gettime and CLOCK_THREAD_CPUTIME_ID... (32 Replies)
Hi
For our load testing , we are using stubs (unix shell script) which send the response to the request coming from the application. As the unix stub is single threaded , it is responding to only one request whereas multiple requests come in parallely.

ppmtosixel
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.
