FSF works with Los Alamos Computers to provide free computers
07-29-2008 11:00 AM
Finding hardware that works with GNU/Linux is hard enough. But if you also want a completely free system -- one that requires no proprietary drivers or firmware to run -- then the task is almost impossible. While resources like OpenPrinting and the SANE database for scanners offer guides to simple functionality, advice on free systems is almost non-existent. To fill this gap, the Free Software Foundation (FSF) has been developing its own hardware list, and, as the next logical step, has been working with Los Alamos Computers (LAC) to develop a line of free (as in speech) computers pre-installed with GNU/Linux.
Hi All, I am pretty new to unix type languages. At work we have a server room with about 50 windows computers in one system and 50 in a unix system. We sometimes have power outages and I don't like the power slam. I wrote a windows batch file using sysinternals help to shutdown the windows... (4 Replies)
Hi,
I need to rcp heavy files between 2 solaris 10/sparc M3000 computers. Currently theses 2 computers are linked via a switch/firewall and the rcp commands take a very long time, I have been told that this is because of the firewall (old one).
I asked my client to by a cross ethernet cable and... (2 Replies)
Here is an easy one.
Count the number of desktops and servers you have running at home, including your home office if you have one.
Don't count those that are in storage or you rarely use, count the ones that are powered on most, if not all, of the day (and night). (86 Replies)
Hello,
I would like to know if it is possible to communicate between two terminals on seperate computers for free - e.g. not using proprietary software or using the built in UNIX terminals on operating systems of the UNIX flavor.
Thanks,

Hello
I've wrote a C++ program which does some mathematical calculations, but the problem is that it takes way too long on any computer to finish.
Is there anyway to make more than 1 computer do the processing so it can process faster? (5 Replies)
i have a computer (sempron 2200+) with Suse 9.3 and another computer with windows 98 (PI 233 Mhz). I'm connect first computer (with Suse) on the Internet through ethernet but second computers in not connect. How can connect second computers on the internet (with 3 network card...two on the first... (8 Replies)

MINIMODEM(1) General Commands Manual MINIMODEM(1)NAME
minimodem - software audio Bell-type or RTTY FSK modem
SYNOPSIS
minimodem --tx [options] {baudmode}
minimodem --rx [options] {baudmode}
DESCRIPTION
minimodem is a command-line program which generates (or decodes) audio modem tones at any specified baud rate, emulating an old Bell-type
or radio-teletype FSK modem. The tones can be played to (or recorded from) the PulseAudio system or to an audio file.
minimodem can be used to transfer data between nearby computers using an audio cable (or just via sound waves), or between remote computers
using radio, telephone, or another audio communications medium.
TX /RX MODE
-t, --tx, --transmit, --write
transmit mode: generate audio tones
-r, --rx, --receive, --read
receive mode: decode audio tones
OPTIONS -a, --auto-carrier
automatically detect mark and space frequences from carrier
-c, --confidence threshold
set receive confidence threshold (0.0 to 1.0, default 0.6)
-8, --ascii
ASCII 8-N-1
-5, --baudot
Baudot 5-N-1.5
-f, --file filename.wav
encode or decode an audio file (extension sets audio format)
-b, --bandwidth {rx_bandwidth}
-M, --mark {mark_freq}
-S, --space {space_freq}
-T, --txstopbits {m.n}
-q, --quiet
Do not report CARRIER / NOCARRIER or signal analysis metrics.
-V, --version
print program version
{baudmode}
The required {baudmode} parameter may be any floating-point value to specify a baud rate, or the string "rtty". The {baudmode} also
implies certain other parameter defaults depending on the rate, including standard (or at least reasonable) default mark and space tone
frequencies.
1200 : Bell202 1200 bps --ascii
300 : Bell103 300 bps --ascii
rtty : RTTY 45.45 bps --baudot --txstopbits 1.5
{any floating point value N}
: Bell-like N bps --ascii
EXAMPLES
minimodem --tx 100
Transmit 100 baud tones from one computer ...
minimodem --rx 100
and receive 100 baud tones on another nearby computer.
minimodem --rx --auto-carrier rtty
Decode amateur radio RTTY signals (listen near 14.085 MHz).
minimodem --tx 0.5
Experiment with very low baud rates (works in noisy conditions).
minimodem --tx 12000
Experiment with very high baud rates works (works with audio files).
NOTES
minimodem does not decode AX.25 framed packets.
minimodem does not support modem control ("AT") commands, nor does it produce DTMF telephone dialing tones.
