IPF, NAT or NIC problem

Thu, 17 Sep 2009 09:13:22 -0700

I'm new in BSD, I installed FreeBSD 7.2 and want to use as gateway with IPF and NAT. I have 2 NIC's fxp0 and rl0. When i booted up my pc i got a message "gateway kernel: arp xxx.xxx.88.17 is on fxp0 but got reply from rl0". My configuration files looks like this:

----rc.conf----

Re: Crazy Idea

Tue, 24 Mar 2009 10:33:13 -0700

There have been some self learning robotics labs that have been working on a robot named Cog for a long time now. I'm not sure what state it's development is at. In the early stages it was just a head two simple camera's and they had to "train it" to follow a light.

If you really want to learn about this stuff, go to MIT. http://www.ai.mit.edu/projects/humanoid-robotics-group/cog/current-projects.html

I remember another where the robot did have the code to learn to walk, but the creators would spend 6-7 hours at a time helping 'teach' the robot to walk while it learned and adapted slowly like a child. Unfortunately at the time hard drive sizes were much smaller and the amount of data the robot learned in order to walk was so much that they didn't have storage for it and the robot would "forget" everything when they turned it off and they would have to train the robot from scratch the next time. This was 5-10 years ago so things have likely advanced quite a bit since then.

In terms of doing this with an operating system or a watchdog program that runs beside the operating system as a user and is allowed to make changes to it... well, that's a big task to get a program to understand the context of it's safety and the consequences of it's choices.

Personally I would start with game AI and pathfinding AI. And with getting your programs to make decisions based on weighing several educated assumptions as opposed to specific facts and static rule based decision making. You'll want to read up on Fuzzy Logic. To over simplify it, it's how to get a binary system that only understands yes and no to understand a 'maybe' or to get the computer to take an educated guess.

Bordeaux for FreeBSD coming soon

Tue, 19 Aug 2008 06:24:00 -0700

Hello,

Over the last couple day's I have been working on the Bordeaux for FreeBSD 7 port. We now have everything compiling and running but a lot more testing needs to be done before it's ready for a final release. Internet Explorer, Steam and Office 2003 are the only applications ive gotten around to testing thus far. The good news is everything that I have tested works fairly well on FreeBSD.

Shared Linux Library converted to FreeBSD one

Wed, 13 Aug 2008 06:24:17 -0700

Hi there,
I was wondering if one could do the following. I have some shared library mylib.so compiled natively in 64bit Linux with the gfortran compiler. I new this was not going to work but I took that library and try to write a simple code which calls it in FreeBSD. Then compile the main.cpp natively in FreeBSD and tried to link the main.o with the mylib.so which was compiled in Linux and it is a native Linux library. I could not link. I got errors.

Do not please tell me to compile the executable in Linux and run it in FreeBSD through the Linux compatibility ABI. I do not want to run a Linux executable in FreeBSD. I do not care. I want to be able to compile code in FreeBSD and link it with this Linux library. In order to do this I should be able to remove any code related to Linux and replace it with the corresponding code (from the object file) a freebsd library should have.

Anyways I could achieve that?

Hello crazy man. I think you watch a lot of movies. Maybe Terminator 2 and 3? How old are you by the way. If you want people to take you seriously then they should know to whom they are talking to.

Your idea is not that crazy. In fact, Solaris 10 has implemented some of your ambitious self-healing and self-learning mechanisms. However, although the filesystem of Solaris (I am referring to the new one) ZFS, has more than 40 patents related to its development Solaris 10 is far away of being a trustworthy platform for everyday development. It has bad compatibility with Laptops and wireless drivers. Bad compatibility with NVIDIA. Parallel performance in Multicore systems is worse than Linux. I have tested that with my own codes. Now take into account the people working on Solaris their number and the effort and the years.

You will change your mind.

If you want to work on something nice, take a look here:
www.menuetos.net

It is a new OS for 64bit and 32bit systems written entirely in Assembly. It is less or about 2 MB and includes too many applications. It is by far the best idea I have came across lately and it keeps evolving. What is missing from there to help it become a widespread is compatibility with the GNU compilers. If you want start working on that.

Any idea as how to make such a thing?, no one in the world has ever made a viable A.I.

hi,

Is there an equivalent command of /sbin/sysctl in linux on solaris 10. If it's "ndd" then please answer the next question below.

Also what are the equivalents parms for linux's tcp_rmem and tcp_wmen

user's terminal's last on modification time

Wed, 13 Oct 2004 08:59:39 -0700

Hello,

I would like to know if somebody can help me with a small program.
I'm writing a program that displays logged on users. Instead of displaying the entry time, I want to display the last modification time of the user's terminal. For example, when i type something on the keyboard and it is displayed on the terminal, the terminals modification time is immediately updated. I want to diplay that time.
how do i do it? which libraries i use.

Thanks you. please reply soon
