The announcement may make it 'official', but IBM has been selling turn-key style clusters for over a year now.
How do I know, and why do I care? 'Cause I work for IBM, and design and build Linux clusters for a living.
We rack purpose-built 1U's (x330's) built for easy large-scale mangement (built-in daisy-chain KVM capabilities, integrated service processor network, cool blinky lights, etc, etc), have internally developed mangement software and system imaging solutions, and ship them to customers at a point where all they need to do is plug them in and log on.
The only real issue is almost no one has a 'standard' cluster application. Almost every one uses a different IPC mechanism, and usually an app is only validated against one very specific software image. So to get the most out of a cluster, customers still need to spend time tweaking.
Maybe someday soon, we'll all be able to 'apt-get install damned_big_cluster', but until then... <shameless>just call IBM.</shameless>
Which actually makes Canadian health care a *regressive* taxation system. The poor pay more (a larger percentage of their income) for the same services as the rich. And would you suggest that rich in Canada cannot purchase better health care if they so desire? Of course they can.
Socialist government policies may raise the *minimum* standards for a group, but they surely do not remove the disparity between the rich and the poor.
Not only are roll-back's on the MySQL developers TODO list... they have been implemented!
That's right, the latest versions of MySQL support a new DB file format (based upon the well recognized Berkeley DB format), and has FULL COMMIT/ROLLBACK capabilities. So no more bitching about that. They've also incorporated support for HEAP tables (emminantly useful for *very* fast cache tables), added better stored function loading, and they almost have sub-selects at the (very fast) speed they want.
I like postgres, it's very powerful for more traditional DB work... but MySQL is still the DB to go to when you feel that need for speed. So check out the feature list of the 3.23.x series. You won't be dissapointed.
Run reliably for... lessee... 3.5 years (and counting) of heavy use without a reinstall, without a crash, and only about 15 reboots. (this is just my system of course... YMMV.)
There are a lot of home-user apps Linux can't run, that windows does reasonably well. But don't suggest that Windows is a serious Network Operating System. I know MSCE's who laugh at that idea.
There... you're NIC is identified as (If I recall the blocks correctly) the first network device cisco ever produced. Your MAC is as meaningless/meaningful as your IP. Just another convention to uniquely identify your computer to the network.
It's configurable via a parameter passed to the kernel on boot. Either add the following...
append="ramdisk=65536"
To your/etc/lilo.conf profile for the kernel image, or boot manually with...
lilo: linux ramdisk=65536
That will give you 64Mb RAMdisk's. You can change it to whatever quantity you may need. I don't believe that it even needs to divide evenly into your total RAM amount. That simple sets the maximum size of the RAMdisks on your box.
The usual disclaimers apply, you milge may vary, etc...but it's always worked for me.;-)
Unless there is a massive loss of productivity, or some untoward activites happening (both of which I doubt are very common), I don't see the harm in some personal use of the network.
Of course, the network is the company's, and most have explicit policies about owning anything and everything on it. So, really, there isn't much choice... scan for porn.
That said... I know that I generally work 10-12 hours a day, as do most people around me. Work is almost every waking hour. (sad, isn't it?;-p) I would not want to work for a company that did not recognise that with the volume of time being spent at work... some private business can and should be able to occur.
I've had a host of annoying small problems with RH 6.0. No the least of which has been an unstable X-server. I'd never had X crash before. Window manager or application, sure.. but not the server. it's too bad. I like the Gnome/KDE integration.
On a side note: has anyone else had problems with gtop after recent upgrades? (on 5.2 systems not just 6.0) I can't trace it to any one thing, but it's stopped working for me. it executes, but just sits there, display's no window, drops no errors. Recompilations, stack traces, nothing is fixing it, or showing me why! *whine*

AMD's yield's are just too low, and they have to mark chips they do produce with almost no safety margin on the MHz rating. (unlike Intel's chips, the majority of which you can overclock to 1.5x to 2x their rating.)
You can get more info here... http://office.microsoft.com/unix/ie/main.htm When I was working for Sun last August, I heard about Microsoft porting IE to Solaris, and out of morbid curiosity, decided to install it on a spare Ultra I had lying around. 60 megs of windows dll's, 48 meg's of regular IE install files later, I fired up my fresh new browser... Ten minutes later, my system started to crawl.. IE had consumed 80 megs of swap, and 60+ megs of RAM. For one browser window. It wasn't leaking memory either (well, not much, AFIK), that was simply what it required to load the COM environment for it to run in.

Ouch.
Timothy, that was a grade A troll! (Oh, if I had moderator points right now)
hehe... the SGI comment was just the right touch.
( For the not-in-the-loop: SGI's 2U servers are just repackaged VA Linux 2200's. )
Thanks for making my evening.

Because the BSD license is less restrictive than the GPL... where the QPL is *more* restrictive. It disallows certian types of distribution.
The GPL is perfectly happy to coexist with any other license, provided that license places no more restrictions on the code that the GPL itself.
So the BSD license, the Artistic license, etc... are fine, since they are actually more 'free' than the GPL is.
Anyhow... the QPL may be free (beer), but it ain't free (speech).

Fine, I'll bite. Not that anyone cares...
What Linux Can Do That Windows Can't:
- Run a stable and fast dynamic-content webserver.
- Useably Multitask under heavy load.
- Run reliably for... lessee... 3.5 years (and counting) of heavy use without a reinstall, without a crash, and only about 15 reboots. (this is just my system of course... YMMV.)

Here's an interesting graph. It may not be all that scientific, but it gives a good idea.
