hi
i was talking to a friend about my Slackware he told me to try Free BSD it is more powerful and a little hard
i asked why?
he send me that:http://people.freebsd.org/~murray/bsd_flier.html
and told me that linux and BSD are better that window$ but if we compare between Linux and BSD we will found that BSD is more powerful and stable
really i don't know what to say so i ask advice?

Yeah, right... First of all, it's a very recent document, as you can see from statements like this
Second of all, well, what would you like to say? Yes, in some areas FreeBSD is better performance-wise, but in yet some others, for example, in hardware support, the situation with BSD is worse. So, at the end it all comes to personal preferences. And, possibly, to licensing and philosophycal issues...To each his own.

then my conclusion is Linux has much support than BSD
am i right?

You're making a lot of subjective statements with no specifics. Try both (and give each a fair shot). See what suits you.

You can also say that the development of Linux is much faster. Even from the document you cited, Linux now has several journaling filesystems, while FreeBSD is still stuck with just one, which is not even journaling. Linux installs and runs on laptops, while FreeBSD on a laptop is still a masochist exercise... Linux offers more choises in about everything, changes and improvements happen very fast. A lot of things is ported from Linux to BSD, I don't hear about any ports the other way around. And of course, Linux community is much bigger...

Now FreeBSD enthusiasts will flame me to death...

I would consider myself a BSD guy after using OpenBSD. Everything is just so well done and designed that I only can tip my hat towards the developers.

It doesn't have same level of hardware support as Linux but it's close. And with wireless cards it's even better.

One noticable thing with OpenBSD is that everything either works or it is not included in the releases. This isn't true to chaotic ways of Linux as everything that seems to work somehow gets added to it in general. This is nice and keeps Linux on the bleeding edge but I prefer the OpenBSD way. Slow and steady

As others have said, both systems have their ups and downs but give both a fair try and then decide.

I wanted to stay away from that kind of talk, but I need to respond to that: FreeBSD on my laptop has been a breeze, and getting my wireless pcmcia (atheros chipset) card + WPA-PSK set up was trivial. Everything needed is included with the base system, and it's clearly documented in the handbook.

Contrast that with my experiences getting wireless set up on said laptop with two different Linux distros (CentOS, VectorLinux) -- what a ridiculous pain. As much as I appreciate the great efforts from the madwifi folks, the setup from start to finish felt like a clunky hack-job.

Yup. As predicted.
Now, I a lappie with an ATI card. The only choice FreeBSD would give me is vesa mode. True? True. For Linux I have at least maybe proprietary, half-baked, but working 3D drivers.
When I bought my previous laptop, it had a broadcom ethernet card. No support for such a thing existed in FreeBSD, peeps on mailing lists were just starting to talk about maybe porting the Linux driver sometime in the future... Now they did it, but now I have a new laptop...
Should I continue? In Linux everything is fast. If it's not here today, chances are it will be here tomorrow, literally tomorrow. With FreeBSD it's painfully slow...

Other than that, I said it in my first post. To each his own.

Actually, I don't think that is correct. But I don't require 3D, so I haven't spent a lot of time playing with xorg on FBSD. We have different priorities (i.e. I like easy to setup wireless, you like proprietary 3D drivers).

I'd rather have my workstation when it's ready and highly stable rather than 'literally tomorrow'. Again, different priorities.

Other than that, I said it in my first post to OP: Try both (and give each a fair shot). See what suits you.

I wouldn't get into too much of a fight there; use what works for you and let him use what works for him. You may want to point out, though, that in OS development, 7 years are a long time, and many things may have changed since the document he referred you to was written.
