I still run kde 3.4.2 on many slackware ran machines, patched to 12.2 . I run kde4 on my ubuntu laptop after giving a fair try to unity. KDE 3 is fine if you do not need all the pnp stuff for wireless, sound etc that used to take weeks to set up on a linux laptop. I used to run fvwm on slackware 1.2.3 and back then, I had a hard time moving to kde because of the awful resource consumed. Same old, same old.
Well, even Linus says kde ain't in such a bad state. I always instinctively stayed away from gnome since it first came out and it had your workspace switching interface in a 3d cube and what not. So, fvwm, xfce, kde. On Ubuntu, install Kubuntu-Low-Fat-Settings.
Kde4 still seems like a pig to me but it ain't as bad as most people pretend. You have to know how to read how much resources your programs really use. Below, in the top output, palsma only uses 28 megs RAM for itself really. My laptop is a thinkpad T43 with one Gig RAM and the total of my workload is about 6 Gigs if you look at the first column that says 300m. Do not let this fool you !

No? it's about getting a 15 millions $ first price instead of a 20 millions $ one. It makes a difference for the one that pays the price at the very least. In the end it's always about the money;-)
ILast I looked, the wiki said a standard Falcon 9 launch starts at $55 million.
SpaceShipOne cost something like $25 million. The prize they won was $10. It's about doing the thing and winning the challenge, not about make stacks of prize cash for it.
I believe a government funded projects won't get the money. It says that the first private group to land a rover on the lunar surface will only get 15 millions $ instead of 20 millions $ should a government funded rover land first.
So if China lands first, they get nothing and first private group to land a rover on the lunar surface afterward only gets 15 millions $.
This post is completely off-topic on this thread./duck. I couldn't reply to any of your replies on Ask Slashdot because there wasn't any from you and I posted late so I just wanted to make sure you read my reply on your question about AD. I almost fell off my chair reading your instructor reply !
Basically, AD is like all Microsoft product. The mentally is that, ultimately, the secretary should be able to admin the system. It is a stronghold for MS products. In 90% of the case, read small to average businesses, AD will be cheaper. In the big iron world, we view AD as a toy although. It cost us a lot less to follow the LDAP standard. Openldap is pretty mature IMHO. Just have samba use openldap or fedora389 as the back end and you will be in business. Expect to spend more time getting a grip on it and configuring it than you would with AD although. Once configured and the knowledge acquired, it cost a lot less than AD for us.

Didn't you notice the modern miniaturized version of on board Beowulf cluster integrated in a chip chips they put it there? I would guess they put about 50 of them in the rack but since it was in fast forward, I couldn't count accurately. Anyway, if they build a Beowulf cluster of those, we will end up with a Beowulf cluster of Beowulf clusters.
Not everybody is time maniacs. I have seen many cell towers off 1000ms. They have highly accurate oscillator but the ntp time sources go out and nobody updates the cell tower ntp client for a year or more. They usually update it when it gets above the 1000ms threshold although because things start to screw up.
Are you guys are saying I could still use them as a tick source even if they are off? Sounds interesting...
Not to mention VMs that will pass through access to a high-precision timing source even if the virtualized tick clock is unreliable.
That was my point 1, although I should instead have written:
"The VM has access to an hardware oscillator".
1) The VM has raw access to the system clock or a pretty good abstraction of it. VMware has had problems with that.
I do not care how it is abstracted or if it is called the system clock. I assume that it might be desirable in VM environments to keep both functionalities separated and that is the point you are making.
An average board with an slightly above average above oscillator work fine for me at +/- 5 ms because I am cheap. Search ntp forums for motherboards with reliable oscillators. I would like VMs to use my oscillator, I do not care if the VM views it as the system clock and or CPU time source or whatever one may call it;-)
Accurate ntp installs indeed use the system clock and rely on it. They just change the frequency on how often OS time is ticked based on information received through the network from other ntp servers.
Ntp in a VM could work under 2 conditions: 1) The VM has raw access to the system clock or a pretty good abstraction of it. VMware has had problems with that. 2) The ntp guest VM process runs at nice -10 to nice -15, and ionice RT while at it;-)
Nevertheless, no ntp will run accurately with a poor physical system clock, more commonly called an oscillator.
I run ntpd on bare metal along with other apps but I run ntpd in a jail (chroot like), just in case. I do reply to public requests but I do not allow queries, ntpdate and other stratum servers requests work fine but you can't ntpq -pn me for example. From ntp.conf:
restrict default noquery
By the way, I am a maniac but I am still satisfied at +/-5 ms. Please do not close my door to hard so it generates a gust of wind towards my ntp server and make it go above +/- 5ms error margin. Not maniac enough to buy a GPS although...

Fuck proprietary AD calls. LDAP is the standard to code apps with. AD has an LDAP interface by the way.

It supports Crysis 3 only. Crysis 1 and 2 are not supported because of some input problems related to the complexity of game controls in 1 and 2.

"The VM has access to an hardware oscillator".
And it can't miss a tick. By tick, I mean a relaxed version of it. Think about dialups where the tick occurs every second.
Simple on paper, harder to implement.
Not to mention VMs that will pass through access to a high-precision timing source even if the virtualized tick clock is unreliable.
That was my point 1, although I should instead have written:

ESXi is a very nice tool, it isn't a panacea. Look at jails and other alternatives and always use the best toll for the job.

Jails work fine too, better IMHO.

I forgot: play with adjtimex to see how ntpd plays with the frequency.
man adjtimex
Accurate ntp installs indeed use the system clock and rely on it. They just change the frequency on how often OS time is ticked based on information received through the network from other ntp servers.
