If you haven't seen it yet, check out the BBS Documentary. I was one of
the
pre-order folks who bought it on DVD... but you can find most of it online

under a creative commons license if you are interested.

Hate to one-up you so early in the game, but there are at least three people here who were *in* the BBS Documentary. :)

You're definitely among friends, though. There are a lot of old-skool BBSers here. We're keeping the tradition alive and moving it forward into the 21st century.

I'm interested in hearing more about OpenVZ. It looks like a great alternative to traditional virtualization if you're ok with everything being Linux. I could definitely see it being used in a situation where you want to have separate development/staging/production systems without having to set up a lot of hardware.

Greetings,

Hmm, I seem to be having some minor issues... with the system... as I didn't see the quote feature... and when I switch between Mail Folder view Bulletin Board view and then try to view all... I get a blank page.  This isn't the right place to mention this so nevermind.

Anyway, cool.  It has been a while since I watched the BBS Documentary and it is good to hear that some folks here were in it.

Regarding one uping or being early in the game... this isn't a competition.  I just enjoy the conversation.  Maybe my previous post sound like I was trying to impress people or something... which really wasn't the case.  It was more of a... I'm an old fart... and I remember BBSes... and I'm glad I've found this place.

I'll do a separate post about OpenVZ.

Subject: OpenVZ - OS Virtualization

[Reply] [ReplyQuoted] [Headers] [Print]

Greetings,

IGnatius T Foobar said he was a little interested in OpenVZ so I thought I'd post some additional info.

First of all, I have used and continue to use a number of virtualization products... the vast majority of which are catagorized as machine hardware virtualization.  They include the full line of VMware products, Xen, KVM, Parallels, and VirtualBox.  Each one of those work great and none of them suck in any significant way.  Virtualizing a whole machine gives you complete flexibility... you can run different OSes / kernels.  That is great but virtualizing a full machine is very resource intensive.

Most of the time though, I want to run Linux on Linux and another catagory of virtualzation comes in very handy... OS Virtualization.  Basically there is a single kernel on the machine and rather than a "virtual machine", OS Virtualizaiton provides a "container".  A container requires a lot less resources than a full virtual machine and as a result it allows for better performance and much higher density than virtual machines.  There are certainly some use cases where OS Virtualization is not suited but a lot where it is.

Most people associate a container with a simple, more traditional chroot'ed environment.  Containers are so much more.  For one thing, a container has its own file system structure that can be the same Linux distribution that is on the host node... or a completely different Linux distribution... with completely different libraries.  A container also has about 20 dynamicly configurable resource paramters... and resource management is much more flexible than with machine virtualization.

I have been using OpenVZ for over three years now and have been very active in the project's community.  During that time I've put together a few screencasts and given a few presentations.  Here are some links:

An Introduction to OpenVZ - http://www.montanalinux.org/openvz-brief-intro.html

OpenVZ Live Migration Demo - http://www.montanalinux.org/openvz-live-migration-demo.html

OS Virtualization vs. Hardware Virtualization - http://www.montanalinux.org/osvirt-vs-hwvirt-presenation.html

I have also conducted interviews with the head of the OpenVZ project and the head of the Linux-VServer project.

If you have any time or desire, check those out and let me know if you have any questions or comments.

TYL,

What's involved in replacing the kernel with an OpenVZ-enabled kernel? Does this make life difficult when you run updates on your Linux distribution, and you've got an OpenVZ kernel there instead of the stock one? (I'm running CentOS 5.2.)

IG T F,

Installing OpenVZ on CentOS is very easy.  I wrote a howto on the CentOS wiki:

Have a look and let me know if you have any questions.

There seems to be a lot of buzz surrounding the new 2.6.29 Linux kernel release.
Dunno why this one's getting so much press.

I see that we now support up to 4,096 processors. Hopefully that will be enough. :)

Btrfs is exciting though. I'm looking forward to that.

its primarily because of there are quiet some performance improvements...

sqlite has become 3 times as fast in some benchmarks

it will speed up firefox & friends who use this.

also SSL has doubled speed in some cases.

on my eee I was having the feeling after upgrading > 2.6.24 that someone hat forgotten the foot on the break.

I hope this will fix that.

yeah, those were the days. Linux actually was BETTER than MS Windows 3.11 in EVERY respect save memory consumption. I too ran it on a 4MB PC for the first little while, and it stank, but you could tell that it had the potential to actually do much more that was useful.

Shortly thereafter, I either upgraded to 8MB or bought another machine that had 8MB. There was an X distribution called "TinyX" that included a version of the X server that was fairly gentle on memory use (perhaps on older version of XFree86), a minimalist configuration of fvwm, and rxvt, which used less memory than xterm. It even went so far as to change the last line of the various X startup scripts to use "exec", because on machines of that era, keeping the extra instance of bash in memory was actually somewhat significant.

This ran pretty well for a while, and was enough to handle Netscape.

Early versions of X really didn't cope well with memory constraints. I had an actual "X Terminal" and it wasn't very useful until I upgraded the 4 MB memory to 16 MB (by swapping out the four 30-pinn SIMM's).

True. It really didn't get modernized until 2003 or so, when the people who knew what they were doing (Keith Packard and Jim Gettys) broke away and did the things they knew needed to be done (such as the Render extension, client-side fonts, etc.)

Subject: Fedora 10 remixes

[Reply] [ReplyQuoted] [Headers] [Print]

Greetings,

I've had quite a bit of fun over the past few months... periodically rebuilding my own remix of Fedora 10.  They actually make it fairly easy.

Somewhat against the spirit of the project my respin includes all of the audio and video codecs that Fedora refuses to ship with (and rightfully so) as well as the Adobe Flash plugin and Acrobat Reader... along with about 10 desktop environments / managers.  With all of that, yes... it is a LiveDVD but it will fit nicely on a 2GB USB thumbdrive.  If you have a 4GB or larger USB thumbdrive it is easy to add persistant storage as well as an encrypted home directory although the maximum size for those is 2047MB.

If anyone is interested in a copy, just email me and I'll reply back with the URL.  I don't really promote it because I don't do much real customization and because of the questionably legal codecs that are included.

If anyone is interesested in learning how to make your own just ask... as I made a screencast on the subject.

I also rebuild the stock GNOME and KDE Fedora LiveCDs just so they are all current with updates as the images provided by Fedora get very outdated very quickly.

Does anyone else here rebuild any other distros?  I'd be interested in learning about that.

TYL,

I had thought Red Hat would put MP3 back into the build after Alan Cox bailed out. Oh well.

Does Fedora require that you install the codecs manually? (Ubuntu just makes you click through a screen that says that you're certifying that you are in a location where it's legal to use them.)

I'm not sure what Alan Cox has to do with it but obviously you had something concrete in mind.  Please fill me in.

No, you will not see Red Hat add mp3 (or any other patent encumbered software) playback (much less encoding) until after the patents on mp3 have expired... which I'm not even sure when that is.  The reason is because... people sue.  Microsoft paid millions in royalties to various mp3 patent holders so they could include mp3 playback and encoding in their products... but some patent holder came out of the woodwork (don't recall who) and sued them... and won the intial case with a settlement over a billion dollars... but of course they are taking it to a higher court.  Acutally that happened several years back and my info is a bit outdated.  I wonder how it turned out.

Red Hat knows they have a big target on their back because they are (about) the only financially successful Linux oriented company.

So far as how Fedora 10 handles third-party codec installs... if you are using a PackageKit powered package manager application supposedly it is aware of the stuff in rpmfusion and will ask you if you want to install a third-party package.  I always add the additional repos and manually install stuff with yum... and haven't given that a try.  Supposedly in the upcoming Fedora 11 they have expanded it beyond just codecs and are now doing fonts as well as applications to handle document types you might now have apps installed for.  We'll see how that works out.  Well actually, now that I have my own LiveDVD rebuild... I just install that and I'm done in about 5 minutes... a fresh, up-to-date install with all of the software I want already there. :)

Alan Cox used to work for Red Hat. He was the one who originally made the push to remove all traces of MP3 support from the distribution.
