Is freeware safe?
Hi there,
I am posting this from my desktop (XP Home Edition) which has Norton I.S 2009 which will soon expire. I also have a laptop I was given which runs on vista home premium (recent clean install) which I have not yet used.
I have a LinkSys wireless-N ADSL2+ Gateway router and I was wondering if some of the free firewalls, anti-virus and anti-spyware software would be a suitable replacement for Norton and which ones to choose.
Sorry for the naive question as I am not a computer techie

Hi,
I am Solaris 9 developer and notice that the documentation does not provide a clear notion of the inherent concurrency in routines defined as "Async-Signal-Safe".
Routines defined as "MT-Safe" obviously have the best level of concurrency, compared to normal "Safe" interfaces.

pnmalias
pnmalias(1) General Commands Manual pnmalias(1)
NAME
pnmalias - antialias a portable anyumap.
SYNOPSIS
pnmalias [-bgcolor color] [-fgcolor color] [-bonly] [-fonly] [-balias] [-falias] [-weight w] [pnmfile]
DESCRIPTION
Reads a portable anymap as input, and applies anti-aliasing to background and foreground pixels. If the input file is a portable bitmap,
the output anti-aliased image is promoted to a graymap, and a message is printed informing the user of the change in format.
OPTIONS
-bgcolor colorb, -fgcolor colorf
set the background color to colorb, and the foreground to color to colorf. Pixels with these values will be anti-aliased. by
default, the background color is taken to be black, and foreground color is assumed to be white. The colors can be specified in
five ways:
o A name, assuming that a pointer to an X11-style color names file was compiled in.
o An X11-style hexadecimal specifier: rgb:r/g/b, where r g and b are each 1- to 4-digit hexadecimal numbers.
o An X11-style decimal specifier: rgbi:r/g/b, where r g and b are floating point numbers between 0 and 1.
o For backwards compatibility, an old-X11-style hexadecimal number: #rgb, #rrggbb, #rrrgggbbb, or #rrrrggggbbbb.
o For backwards compatibility, a triplet of numbers separated by commas: r,g,b, where r g and b are floating point numbers
between 0 and 1. (This style was added before MIT came up with the similar rgbi style.)
Note that even when dealing with graymaps, background and foreground colors need to be specified in the fashion described above. In
this case, background and foreground pixel values are taken to be the value of the red component for the given color.
-bonly, -fonly
Apply anti-aliasing only to background (-bonly), or foreground (-fonly) pixels.
-balias, -falias
Apply anti-aliasing to all pixels surrounding background (-balias), or foreground (-falias) pixels. By default, anti-aliasing takes
place only among neighboring background and foreground pixels.
-weight w
Use w as the central weight for the aliasing filter. W must be a real number in the range 0 < w < 1. The lower the value of w is,
the "blurrier" the output image is. The default is w = 1/3.
