Hello, I won't argue for / against Linux / BSDs but there is a reason why Linux Powers 95% of the World's fastest Supercomputers [ http://www.top500.org/stats/list/34/osfam ] even though its arguably the youngest entrant into the *NIX family. It is also steadily finding its way into the smart-phone arena (android /meego / Maemo / WebOs / etc; I understand there is some vanilla BSD on the iPhone) — not to mention everything in between. I admire both set of systems and would use the most appropriate one to get the job done. Someone posted an in-depth article about the variances of FreeBSD to Linux users [ http://www.over-yonder.net/~fullermd/rants/bsd4linux/bsd4linux1.php ] Another guy also tried to put FreeBSD in Perspective and this is what he had to say: " Everyone will have a different opinion, and they are all right. I'm going to offer my FreeBSD-slanted opinion as one view. NetBSD Coke, original formula. Hard to argue with that. NetBSD has a long and noble history. The NetBSD team does a great job of covering the hardware world. No, not the WinTel hardware world, that's Linux. They cover platforms. By running on so many platforms it is a great platform if you have a lot of different (and/or old :-) sorts of hardware. Unfortunately, it is this platform compatability that slows their progress. I have nothing bad to say about NetBSD. unfortunately, I have nothing good (feature wise) to say about it when it comes to getting real work done. Anything you buy these days has "better" choices that run on it. I will continue to be a big NetBSD supporter though, as it's the only choices for some of my older machines that still deserve a real operating system. OpenBSD I'd tell you about it, but then I would have to kill you. :-) Actually, it's not that bad. OpenBSD is security focused, and so they do go a few extra steps in that direction. About 60% of what they do can be done on NetBSD simply by intelligently securing the box. The other 40% is good security add on work. Most of the good stuff the OpenBSD folks come up with make it into the other BSD's and Linux shortly afterwards, although not all. I'm not sure on security alone OpenBSD is "better", assuming you have a clueful admin who understands the issues.IMHO the best thing for the BSD community is if the OpenBSD guys and the NetBSD guys could get together. Unfortunately, the inability to do that is the very reason they are apart. FreeBSD The FreeBSD folks want to get real work done. Early on, that resulted in an Intel focus, as that was the only affordable platform available. Now the Alpha is included, and hopefully more soon. When they day is done though they are interested in bang-for-the buck, not on RC5 or quake, but applications like web, ftp, and news. Bread and butter network stuff, rooted deep in the Unix world. This shows in several places. The VM subsystem they implemented several years back was one of the first of it's kind in the free OS world. The port subsystem is an efficient way to distribute and build tools that may still have compile-time dependancies and configuration without creating a packaging nightmare. The installer is simple, clean, fast, and good for the novice and the expert. Put simply, FreeBSD makes the admin and the machine the most productive when trying to do Internet application "stuff". Linux I'll offer my Linux opinion, to complete my perspective. Linux wants to be everything to everybody. As such, it supports more "options" to everything. There are more device drivers, more supported file systems, and more "applications" than any other free unix. In many cases, this is good, but when it comes to getting real work done, it is questionable at best. The quality of both some of the "supported" hardware and the drivers are to be questioned, but how are you to know what is good, and what is bad? The releases are more frequent, both to fix bugs, and introduce features. There are often all sorts of new things added you don't need that may affect what you're trying to do. Summary Any of them will probably do what you want. All of the BSD's have a very different structure than Linux, not only in code, but in how they are designed, built, and released. They all have core teams, rigid code review and testing procedures, and an emphasis on being correct rather than being first, best, or fastest. For the most part, if there is a feature in a released version, it works, reliably. Linux emulation on FreeBSD works like a dream. If RealPlayer G2 and acroread will run fine under it, anything will. The penality for this stability and reliability is that you're doing to have to pick from the "approved" hardware list, and do without some of the wizbang stuff. Finally, I have one recommendation. Learn the way each OS wants you to do things. Unix is Unix, unless you're an admin or a programmer. The worst thing anyone switching OS's can do is try to impose one OS's / designers view on another. It's usually a poor fit. Just because one OS does something completely different than another does not automatically make it better or worse, what matters is what you are able to do with it at the end of the day. " Good luck with whatever you choose (to the guy who was asking which *BSD flavour to choose in another Skunkworks thread). Regards, Martin.
