Canonical offers paid support for every Ubuntu release. The difference between releases is only how long there will be security and bug fixes.
Ubuntu is supported (in terms of bug fixes) for 18 months for non-LTS releases. On an LTS it used to be 5 years support for Server and 3 years for desktop. 12.04 LTS will have 5 year engineering support for both Server and Desktop editions.
Since when is Gluster an OpenStack project? Gluster is merely one way people can store their EBS volumes. I expect plain old iSCSI to be one of the most common ways. Or you can use gluster, or ceph. None of these are official OpenStack projects.
And if you look at the feature set and roadmap of HekaFS (a Red Hat project which rides on top of gluster) it's pretty clear that if anything Red Hat will guide the development of gluster in ways that will make it even more suitable for an OpenStack deployment than it is now. They are adding things like multi-tenancy, stronger authentication, encryption etc.
Personally I'm more excited about ceph, but gluster just got more interesting for OpenStack, not less.
The article is a little stale (they are running over 7000 Ubuntu desktops today) but in terms of OOo, they migrated across the board from MS Office in 2005. We're talking well over 50,000 users, iirc.
a) my understanding is that newer versions of powerpath will detect kernel updates and recompile/reinstall themselves. don't know for sure. not a big fan of PP. b) yeah, how come Novell doesn't support EMC's software? what creeps. c) ocfs2 will be fine it's in the kernel. d) best solution: drop powerpath and use native linux mpio and never have to worry about that kind of shit again. the performance gains that powerpath provides are marginal in most scenarios. afaik, it really comes down to "true load balancing" (according to EMC) vs. "round robin". Usually not a an issue when most loads wouldn't saturate one HBA, much less two. For most cases, multipath is really more about failover. So why add the extra layer of support confustion?
Are you seriously using 11 on production servers? We've yet to upgrade to SP3 of 10. 11 breaks a lot of things. Where did HA go? Replaced by some proprietary package.
HA was not replaced by a proprietary package at all. It was moved out of the default SLES install into an "add-on product" called SLES 11 HAE (HA Extension). It's still based on 100% open source components. Of course, it's an enterprise release and subscriptions are licensed separately. That's really the big difference, it's not included with SLES any longer. I believe this is the same model RHEL/RHCS uses. For what it's worth, she HAE actually one of the best improvements in SLES 11. Now based on OpenAIS instead of HeartBeat and is much more functional and configurable compared to SLES 10 HA (or Red Hat Cluster Suite for that matter). And I'll just add that RHEL still doesn't offer a supported DRBD implementation.
Will VMware tools work with the 11 kernel? Nope, sorry.
VMware tools work fine with the 11 kernel. I can't tell you how many SLES 11 images I have set up with both VMware Workstation or ESX, dozens at least, and I installed VMware-tools on all of them. I have seen an issue with some ESX 3.5 tool package builds. It doesn't happen in every case, if I recall, but when it does you'll see an error enabling the "paravirtualized scsi driver". One fix for this I know will work is to update your ESX to version 4. I believe this only happens with certain builds of 3.5.
We've yet to upgrade to SP3 of 10. 11 breaks a lot of things.
On the subject of stability, you shouldn't be waiting to update your SLES 10 to SP3. Many stability improvements in SP3. Honestly 11 seems pretty rock solid to me, but it's hard to tell since a lot of customers wait for the first SP to be released and tested a little before deploying to production.
Good article, but it does one thing totally wrong in the title and throughout the article. Something thankfully the Slashdot title and blurb actually gets right. It's not a big deal, but I get tired of reading articles about "tech workers" and "IT workers" when they are about programmers. I sure a shit would love to know how this stuff applies to Admin, tech support, sales engineers, consultants, etc.
Don't get me wrong it's a minor--and essentially off-topic--point, but the article is riddled with phrases that equate IT with software development. No offense to programmers, I love you guys too, but damn it's annoying.
Yup. NetFlix dances around the issue (see: http://www.joystiq.com/2009/10/26/netflix-ps3-disc-must-remain-in-system-until-2010-update/ ). But it's pretty obvious this is the reason why.
I don't think firmware QA is the primary reason here. It's an app. There's not much difference between QAing an app loading from local storage vs. an app loading from disc.
Actually at this point, PS3 Netflix streaming is superior to the Xbox solution... you might need to put a disc in, but you don't need to fork over $50/year for an Xbox Live Gold membership.
Funny you should say that- it actually can run linux- and is a pretty straightforward process supported by Sony.
This was true for the first several generations of PS3s. But the "Install Other OS" feature has been removed in the PS3 Slim and is not expected to return.
I don't see how it had much to do with Windows. He could have blown out the NetWare server with a new copy of NetWare or Linux for that matter. I think the bigger point is that the guy installed a new OS on the network server. That's pretty dumb.
Not to mention, private schools and Catholic schools are allowed to kick out students much more easily than public schools. I don't think I have to explain why that makes a huge difference.
Therefore, disruptive or difficult students are simply expelled. On the other hand, a public school will sometimes have trouble expelling a violently disruptive student because such a child has a disability.
I'm not saying it's wrong. I'll leave the value judgement to you. But it does skew the statistics a hair.
two points (although probably for naught as this thread is getting old).
1) Did it occur to you that maybe this is only a debut, and will LIKELY spread to many other endeavors both sporting and otherwise? Only events this huge can justify this kind of inital investment. But in time this will obviously change. just hold your horses.
2) You shouldn't make a big deal out of how idiotic you think football is. as your links tell me, you happen to be obsessed by playing computer games over a LAN. Now I think that is fun too, I also like football. now a LOT of people make fun of computer game players, and so just as it is ignorant to say that pc games are stupid and mindless, your comments are equally silly. you just don't happen to like football, that's it. end of story.
I didn't like bozo jocks in high school either, but I like football. sorry you think I'm a moron.
3) The number one senator in favor of the monopoly ruling is Orrin Hatch, the Republican Senator from Utah who is also chairman of the Judiciary Committee. Recall Caldera is in Utah, and they've already had their case with DRDOS against Microsoft.
Whoa, the Caldera lawsuit may be instructive to Senator Hatch. However, I believe he has always been more interested in the fortunes of another Utah-based company, that is, Novell ($2.4 billion market cap) rather than Caldera ($89 million). He's just, I think, more practical. Interestingly, Novell was the last owner (after buying Digital Research) of DR-DOS before Caldera acquired it and filed suit.
Having said that, I completely agree with your comment.
I think for most system administrators who wanted (or were forced) to implement something like this it wouldn't really matter if it was perfect. Same goes with standard web blocking software, if it makes it very difficult and blocks 98-99% of the sites, that's just fine.
Sure it's possible to find ways around just about anything, but for your typical user it doesn't take much to stop them.
Where I work we have security software that we set to block the start button and running any appications named setup*.exe or install*.exe. That is ALL it does, and do you know how much that cut down on unauthorized installs? Good God!
You want to know how desperate MS is to get people using Windows 2000 server?
Go to Dell's web site and price out a PowerEdge server as if you were an educational institute. It's actually cheaper to get Windows 2000 Academic with 5 CALs than it is to get Red Hat 6.2 (without printed documentation!). Wow. I mean I know it's the educational discount, but how the fuck can it be cheaper than FREE ?!?
I have been using emusic.com for about 3 days now and have downloaded, oh, about 5 gigs already. But, on the other hand, they have music I want: they have almost the entire Amphetamine Reptile Records catalog (the cows!) and Frontier Records (every Thin White Rope album!!!!) and from what I can tell a pretty decent blues section with a decent amount of good old junky delta blues. It's extremely hit or miss because only some indie labels are participating. But in my case I got to scoop up some records that I know are already out of print and in the case of Amphetamine Reptile Records they are pretty much closing up shop. I am so happy to have gotten some of this stuff in a digital format before it's gone. And just for fuck's sake I have downloaded a LOT of stuff I've never heard.
I've been downloading so much I think I may single-handedly get emusic to reconsider the program;)
Seriously subscription services are the way to go... I get to pay the artists while retaining the freedom to sample music at will without watching my budget... Emusic also sells by the track (99 cents) but, shit I'd owe them about $1500 right now if I paid that way!
I highly recommend going to emusic and browsing around a little... in my case it took about 5 minutes to decide they had enough to justify $20 (you only get the 9.99 price if you commit for 1 year... if you commit for 3 months the price is $15). Sure it's one of those lame auto-renew unless you cancel it deals... but they are very upfront about it and have cancel button right at the top of the page when you log in.
Someone's going to think I work for them but I'm just a VERY satisfied consumer who can't quite get over the wierd feeling of getting MP3's legally:)

128 pixel icons, fat borders
Also, these can be configured as well. If by borders, you mean the fat drop shadow, that takes a little manual theme hacking:
cd /usr/share/themes/Ambiance/metacity-1
sudo $EDITOR metacity-theme-1.xml
Search for:
shadow radius=”45.0"
And change the shadow radius to a smaller number.
Like auto-hide, the size of the icons can be configured in CompizConfig Settings Manager (ccsm).
Add that to the stupid auto-hide (I HATE auto-hide!)
You can disable autohiding in ccsm (compizconfig settings manager) . I do.
Here's one example:

Whenever I had to admin a windows network, this is the one goddamn key I wish my users would have hit before picking up the phone.
And now they won't because they don't want to get virus?
I mean, I don't really care any more since I support Linux, but, shit man, I feel bad. That's just not right.

That was very polite of you. You could have gone with this:

Seems like a decent tradeoff.

Disabling telnetd is not the same thing as "disabling telnet".
You are correct that telnetd is almost never enabled on servers. That just means a telnetd server that allows insecure login isn't running on port 23.
You can easily use the telnet client (even on Win XP) to connect to services on other ports, like port 80. Just as was suggested above.
When I admin or support mail systems, I use telnet all the time to connect to port 25 to simulate a SMTP session.
Even in the US, metric is quite commonly used when measuring fizzy drinks or drugs.
I don't see how it had much to do with Windows. He could have blown out the NetWare server with a new copy of NetWare or Linux for that matter. I think the bigger point is that the guy installed a new OS on the network server. That's pretty dumb.
You should do what you are good at.
Two things Russians are very good at: hacking and organized crime.
When combined, it's a sight to see.
Therefore, disruptive or difficult students are simply expelled. On the other hand, a public school will sometimes have trouble expelling a violently disruptive student because such a child has a disability.
I'm not saying it's wrong. I'll leave the value judgement to you. But it does skew the statistics a hair.
Actually I believe they just scanned the digits of Pi until they found the right program.
Similarly Fark never gets Farked.
