Matt Dillon On FreeBSD 5.0 VM System And More
JigSaw writes: "OSNews features a very interesting interview regarding FreeBSD 5 with the guy responsible for the very good (technically) FreeBSD VM among other things. Matt Dillon talks about everything: FreeBSD 5, Linux, .NET and much more. Additionally, OSNews also includes two mini interviews with the NetBSD and OpenBSD head developers."
Consider one of Dillon's points: "A great deal of what people label as 'Linux' isn't actually Linux."
As a long-time FreeBSD user, I am fascinated when Linux users go to bat citing so many popular open source applications as Linux applications. Very few of the thousands of applications out there need to run in Linux "emulation" mode on FreeBSD. Almost all applications build and run similarly on FreeBSD as Linux.
I read print magazines such as Linux Journal and visit many Linux web sites, knowing that the content is very much applicable to my OS of choice.
I think Linux is going through a somewhat painful transition as it moves away from a Wild-West/Darwinist development methodology into something a bit more thoughtful. I will admit to wanting to take a clue-bat to some of the people arguing against Rik's VM work who simply do not understand the difference between optimizing a few nanoseconds out of a routine that is rarely called verses spending a few extra cpu cycles to choose the best pages to recycle in order to avoid disk I/O that would cost tens of millions of cpu cycles later on. It is an attitude I had when I was maybe 16 years old... that every clock cycle matters no matter how its spent. Bull!
This has got to be the BEST description of the Linux development to date that I've heard! (And it's got me rolling on the floor with laughter!)
Seriously, when are people (in Linux, Windows, C, C++, Java, etc. camps) going to learn that design is paramount? We don't design things because we are old farts who have no clue about "how to make a system fast", we design them to get the best tradeoff between performance, stability, structure, and maintainability. Anyone who says "I don't care about those things" is talking out of his ass and will not truely become a good programmer until (s)he can admit that code should be well designed.

The Linux VM can easily bring my system to a complete halt under high memory usage (by no means extreme). That is not to say FreeBSD's VM that great -- I've never tried it, but it has a good reputation. I mean to say that Linux's VM is disgraceful.
In regards to the desktop... well, I'm not sure exactly what you are asking. Both Linux and FreeBSD are in the same boat there... the only way to drive desktop acceptance is to ship machines pre-installed with the OS (whatever OS) and preconfigured with a desktop so when you turn the thing on, you are ready to rock. The only way to do that is for the PC vendors to pre-install Linux (or FreeBSD, or whatever).
I think this is bunk. As he pointed out earlier open source software is a poor candidate for commericial support. I think it is a poor candidate for pre-installation too. No self respecting sysadmin would want Dell to preload Linux or FreeBSD for their companies desktops (or servers). It is a far easier to support systems that are configured in the same manner and style and each sysadmin has their own preferences which become company policy. If we are talking about pre-installed systems for the home market than ok - it would be a selling point. But I think the market for such a system would be so low as to make it not worth the cost to a large company like Dell.
None of the open source operating systems are ready for the average home users desktop. The desktop environments need to be stable and established. The system update procedures as simple as Windows Update (apt is very close but not enough). There are too many rough edges right now for the average user. Compare the rate of change in the Windows desktop to that of KDE or Gnome. KDE and Gnome have to change because we demand and expect the same ease of use that the Windows desktop environment provides but in the same vain they won't be useful for the average user until they stabilize.
Can you imagine dumbed down debian with a graphical installer and a graphical web-based update like windows update? Instead of seeing all the package details we would only see the meta packages that hold all the updates for a particular component like KDE or X11 or the base system. A simple click and the download and upgrade begins... I'm sure some of us would be horrified by the idea of dumbing it all down so much but I think it will be neccessary - and I wouldn't mind running such a system as my stable desktop while running something a bit hairier on my development system.
No, you're not. I'm a Linux user, and this trend irritates the living hell out of me. I don't grok the need for 47 tiny libraries to write a mail client*, especially when nine times out of ten half of the required libs were written by the same guy for the same project, but distributed separately (never to be used by another project).
* For the truly anal retentive, that was a bit of hyperbole. But not much.
Just like all the Linux distros should?
