On top of that, I am quite certain that this isn't going to affect upgrades at all.

The partition layout/filesystem types that you had before are going to be the ones you have after just like the vast majority of upgrades before now.

So no one's existing files are going to be affected.

There was already a yum plugin for this (yum-plugin-fs-shapshot) as far back as F13 as mentioned here: http://fedoraproject.org/wiki/Btrfs_in_Fedora_13

It will do an automatic btrfs snapshot of affected filesystems before every yum transaction so that you can go back to whatever point you want. Also, since it is partition dependent, you can rollback your system partition and not undo changes you may have made to your home directories if you have those on different partitions.

btrfs is quite powerful but I have found that the user/GUI tools have not come up to speed yet. I have been using btrfs from my F15 netbook and it seems to have caused no issues so far. However, enabling transparent compression and any tweaking has entailed editing /etc/fstab (never a thing to do lightly) and command lines.

Hopefully some of the GUI disk management tools will start to make available some of the capabilities of btrfs.

DD-WRT does support IPv6 and has some setup info here:
http://www.dd-wrt.com/wiki/index.php/IPv6

While the native firmware may not, OpenWRT and DD-WRT bring that support to a lot of routers.

When you sign up with a tunnel broker, you get a ridiculous number of IP addresses assigned to you (you get a whole subnet). So I think once people get the hang of it and their are rubber stamp solutions available, NAT will die off.

Unfortunately, the same is true for any peer to peer protocol. NAT breaks the Internet and there will never be a perfect workaround.

Never say never. NAT will mostly die out with IPv6 given that each person could have many directly routable IP addresses and there will still be lots left over. You switch over for free right now with a tunnel broker if you want.

The auxiliary security aspect of NAT will keep it around for a while I think. But there are better options and a simple firewall rule on the router can replicate the same thing if you only want outgoing connections.

Sadly, Google Voice is not available to non-US users. Also, even if you lived in the US and obtained a Google Voice account, it is not usable when abroad. I am in that situation now unfortunately. If I use a VPN to connect out of the US, the Call option shows up in the GMail interface but not otherwise. It is kind of bizarre for them to limit this since computer to computer GTalk is not limited and it wouldn't seem to use up any more resources.

Actually, Matt Domsch is from Dell ... not Redhat. So you can take the tinfoil-hat-of-conspiracy off (or put on another layer depending on your feelings towards Dell). This change is coming from an actual *need* from a certain segment of Linux users/admins. I suspect anyone who has had to deal with NIC failure/reconfiguration on a system with more than 2 cards will welcome this as it is trying to take advantage of newer BIOS technology to deterministically assign names to cards based on the actual physical location. Those with 2 or less will have to do little to no work in order to adapt to a change in nomenclature.

This change won't affect desktop people at all. The vast majority only have one NIC and they don't even know/care what it is called since Network Manager takes care of everything. Also, there are bug days being scheduled tomorrow to make sure that all the wrongly hard-coded scripts and programs are flushed out and fixed so hopefully we have a more manageable system going forward. If you care, participate in the bug days so that this change can be seamless:

The N900 is the way to go just for its flexibility:
- no complicated jail-breaking needed or fighting with upstream to keep control of your phone's internals
- can install a full Openssh stack or the lighter Dropbear if you don't need all features
- several VNC clients available
- full non-crippled browser
- custom kernel available enabling various networking and filesystem modules
- great contact manager with great VOIP connectivity (gtalk/SIP/Skype all even though 3G)
- recently available custom wireless driver that allows full security testing (packet injection, full moitor mode, etc.)
- and many more ...

While the N900 might be a bit too much of a power tool for someone looking for a simple phone that works well, it is ideal for a technical person with Linux knowledge that can really take advantage of the wide-open underlying Linux base.

My only gripe with this phone is the battery life. You have to charge it every single day. Not a huge deal since it can charge from any USB port but still annoying on extended trips.

Nominum Calls Open Source DNS "a Recipe For Problems" 237

Posted by Soulskill
from the dem's-fightin'-woids dept.
Raindeer writes "Commercial DNS software provider Nominum, in an effort to promote its new cloud-based DNS service, SKYE, has slandered all open source/freeware DNS packages. It said: 'Given all the nasty things that have happened this year, freeware is a recipe for problems, and it's just going to get worse. ... So, whether it's Eircom in Ireland or a Brazilian ISP that was attacked earlier this year, all of them were using some variant of freeware. Freeware is not akin to malware, but is opening up those customers to problems.' This has the DNS community fuming. Especially when you consider that Nominum was one of the companies affected by the DNS cache poisoning problem of last year, something PowerDNS, MaraDNS and DJBDNS (all open source) weren't vulnerable to."

Microsoft Says No TCP/IP Patches For XP 759

CWmike writes "Microsoft says it won't patch Windows XP for a pair of bugs it quashed Sept. 8 in Vista, Windows Server 2003 and Windows Server 2008. The news adds Windows XP Service Pack 2 (SP2) and SP3 to the no-patch list that previously included only Windows 2000 Server SP4. 'We're talking about code that is 12 to 15 years old in its origin, so backporting that level of code is essentially not feasible,' said security program manager Adrian Stone during Microsoft's monthly post-patch Webcast, referring to Windows 2000 and XP. 'An update for Windows XP will not be made available,' Stone and fellow program manager Jerry Bryant said during the Q&A portion of the Webcast (transcript here). Last Tuesday, Microsoft said that it wouldn't be patching Windows 2000 because creating a fix was 'infeasible.'"

The Orange Goo That Could Save Your Laptop 285

Barence writes "A British company has patented what can only be described as an orange goo that could save your laptop or iPod after a nasty fall. The amazing material is soft and malleable like putty, but the substance becomes solid instantly after impact. You can punch your fist into a ball of the material sitting on a desk and not feel a thing, according to the staff at PC Pro who have been testing the material, called 3do. It's being used by the military, the US downhill ski team, and motorcycle clothing manufacturers to provide impact protection in the event of a crash. However, it's also appearing in protective cases for laptops and MP3 players."

From the article: '"It's sort of like a swimming pool that hasn't been cleaned in a while." The blob, Konar said, is a microalgae made up of 'billions and billions of individuals.'"

Does Bing Have Google Running Scared? 560

Posted by kdawson
from the or-perhaps-maraschino dept.
suraj.sun alerts us to an anonymous-source story up at the NY Post, not what we would normally consider a leading source of tech news, claiming that Microsoft's introduction of Bing has alarmed Google. "...co-founder Sergey Brin is so rattled by the launch of Microsoft's rival search engine that he has assembled a team of top engineers to work on urgent upgrades to his Web service, The Post has learned. Brin, according to sources..., is himself leading the team of search-engine specialists in an effort to determine how Bing's crucial search algorithm differs from that used by [Google]. 'New search engines have come and gone in the past 10 years, but Bing seems to be of particular interest to Sergey,' said one insider, who spoke on the condition of anonymity. The move by Brin is unusual, as it is rare these days for the Google founders to have such hands-on involvement in day-to-day operations at the company, the source added." CNet's coverage of the rumor begins with the NY Post and adds in Search Engine Land's speculation on what the world of search would look like if Yahoo exited the field.
