I have a Gmail account, and I played it with all of a few hours before I gave up on it. I realized how limited it's filter rule options are. Other just just flexibility in what it does have, it's biggest lacking is the ability to filter by e-mail headers.
Here is a good example. I want to give out unique to addresses to everyone. Which Gmail does nicely support with extensions, in the form of user+extension@gmail.com, aka bob+mailinglist@gmail.com. But then say I receive an e-mail to that address from a mailing list that replaces the To: with itself. Now how am I to filter out messages to my unique To:? Yes, I could filter the mailing list by it's To:, but then people often do silly things like To: bob@hotmail.com CC: mailinglist@mailing.com.
Another piece is how great everyone says Gmail's spam filter is. Well if it is go great, then why is my Gmail inbox full of spam? Plus it is completely uncustomizable. If I am having a problem with a certain type of spam, and I going to be able to get Gmail to add a new rule? Even if I could request one, is mine going to get done with the million other requests?
My office uses Thinkpads exclusively. I would say maybe the failure has gone up some since Lenovo took over, but depot times have always been fast. I just turned in a hard drive RMA today, and I will probably have it with advanced replacement by Monday.
They also seem to be having sales all the time these days. Which means prices have come down.
The second is reject_unverified_recipient. It is a way for it to check downstream MTA to see if it accepts the e-mail address. This is good for a filtering border MTA, which then passes to the the downstream server. It does this check before queueing. See http://www.postfix.org/ADDRESS_VERIFICATION_README.html#recipient for details.
I have been using them for years. They are cheap, their website is good enough, and never had a problem with them. In the beginning when I talked to their tech support for something they were very friendly and helpful.
Yeah, I understand the problem of allowing developers setup production boxes the way they want, instead of the proper way. I have to deal with the same thing at work. All the systems were setup by consultants/developers before I was hired. It has been a uphill battle to migrate the systems to a sane setup. I am getting there, but it is slow moving.
Mostly it is applications installed from tarballs instead of packages. Some of it is the choice of application and configuration.
The article seems like a good one, though I think it may be a little too cautious. I would need to hear some real world examples before I would give up on incremental backups. Being able to store months worth of data seems so much better than being only able to store weeks because you aren't doing incremental backups.
One thing not mentioned is encryption. The backups should be stored on a media or machine seperate from the source. In the case of the machine you will likely be backing up more than one system. If it is a centralized backup server then all someone has to do is break into that system and they have access to the data from all the systems. Hence encrypted are a must in my book. The servers should also push their data to the backup server, as a normal user on the backup server, instead of the backup server pulling it from the servers.
I used to use hdup2, but the developer abandoned it for rdup. The problem with rdup is it writes straight to the filesystem. Which brings up all kinds of problems, like the ones mentioned in the article. Lately I have been using duplicity. It does everything I want it to. I ran into a few bugs with it, but once I worked around them it has worked very well for me. I have been able to do restores on multiple occasions.
He claimed it was a USB wireless card in the Defcon talk. He was definitely lying about what exactly he used. I figure he either faked using an external card, or it was a new expresscard.
I did see a wired gigabit expresscard at Fry's the other day. So expresscards are out already.
There are plenty of howtos out there of how to get XP running in Xen. They were very helpful, but I did struggle for a few days to get it working.
The first hurdle was I was using noapic with the Xen kernel when I didn't need to. The reason I used it was that I have to use it for consistent booting with a normal kernel. The second problem I ran into is that Fedora's copy of the Xen kernel is broken for booting XP. Setup would boot, but would always hang at "Setup is starting Windows". Finally I took the suggestion I found online of using the raw upstream version. Then I fought with making a initrd until I remembered mkinitrd. Then it worked.
Then the mouse didn't work well, and the graphics were poor. People said the best method was to actually remote desktop into the XP in Xen. At that point I decided Xen needed a lot more work before I would want to run XP in it. So I went back to VMware Workstation. It was nice to see hardware virtualization working though.
The Core Duos have hardware virtualization, as do AMD's AM2 based Athlon 64s. So the Core 2 Duos aren't the first.
I have personally used Linux with Xen to run Windows XP on my Macbook Pro. The Macbook Pro has a Core Duo in it. Windows won't run in Xen without hardware virtualization, or a hacked copy that was never released.
I think Theo is crazy for wanting a compiler with little or no optimization. It would make his life easier for development, but completely screw the user. From everything I have heard gcc isn't good enough at optimization.
Nvidia is far from perfect, but they do a lot better than ATI when it comes to binary drivers and support.
Not sure why you are having a problem. I am using a 6200 on a x86_64(Intel in this case) system with the binary drivers, nvidia-glx-1.0.8178. I have a x86_64(Athlon X2) system at hoem with a 6600 using the binary drivers too.
My power bill a few months ago was around $175. Then I tweaked my computers for low consumpution and the next month it was $155. The problem was not the computers, but the electric heater. It wouldn't turn off, so was at least partially running all the time. I got it fixed and this month my power bill was around $105. During none winter months it has been $60-100 in the past.

The computers, excluding the laptop, are on at least three networks. They go out over their primary internet connection, but can be accessed over both cable and dsl. The dsl is mainly for the server and the cable is mainly for the other computers.
I don't see any Core Duos in my future if they have those bugs. Some of the ones they aren't going to fix do sound like they could easily crash programs. Though realistically it wouldn't surprise me if Athlons and P4s already had similar bugs I didn't know about.
I have been using 1.5rcX for a while and just upgraded to 1.5. I use it with imap and haven't experienced your terrible IMAP bugs. I have seen plenty of problems before when using evolution. It was always having some problem, but I haven't had any serious problems with thunderbird. What imap server software is running on the server you use?
I have been using 1.5rcX for a while, and just upgraded to 1.5. In both saving a draft to an imap server works fine. Maybe it relates to your configuration or imap server. I am using the default configuration and the server is cyrus-imapd.
I just tried it on a server using dovecot and it didn't work when the folder didn't already exist. The folder was create, but it just spun it's wheels. I hit cancel, and tried to save it again through the file menu. It acted like it saved, but didn't. Then I tried closing the window it asked if I wanted to save. I told it yes, and it did save it.
I completely agree with you about Norton. It just all around sucks. I spent a few hours the other day trying to get Norton Internet Security 2006 to install on an XP box when the client insisted. I finally just gave up and told them if they wanted Norton it would required a format and reinstall. As for McAfee, the home versions only suck a little bit less than Norton. At the office we use and sell McAfee ASAP. When it started it was Awesome. It didn't have a single popup, and even said that was the design goal in the help. Lately it has a little popup happy, but still isn't nearly as bad as the home product.
The worst example I can think of with the home version is that it would detect a virus, and popup saying I found a virus what would you like to do. You would like continue, and it would say would you like to start a virus scan now. You click Yes, and it starts a scan. Then you get another popup saying it detect another copy of the virus, you click continue, and even though a virus scan is already started it asks if you want to start a virus scan again. So if it found 200 copies of a virus you would have to click 400 times to shut it up.
I am a fan of AVG's free version. I was originally turned off by it a few years ago when I installed it on a Windows 98 computer and it would report that it found a virus by taking me to a fullscreen DOS screen. But recently I tried it again and that problem seems to be gone. I have been telling people about it regularly lately.
I am also a fan of clamav. I use it on my mail servers to help filter out the viruses. The mail reason I do it at home is to keep my mail folders a reasonable size. About a year and half ago I found probably 50mb of viruses in my spam and mailing list folders. Cleaned them out and installed clamav with amavisd-new. Haven't had a problem since.
Yeah, 6E040L0s, low profile drives, and OEM drives. My last one to fail was a refrubished drive that I had gotten back from RMA. It stopped spinning up. I had to drop it a few inches to get it to spin up so I could get my data off.

Postfix has plenty of options to deal with this issue.
The first is check_recipient_maps. See http://www.postfix.org/uce.html#smtpd_recipient_restrictions for details.

NetSol isn't stable in all cases. Don't let them host your domain on their dns servers, unless you like like regular problems.

Actually, retail x6800 extremes at least the easiest to find. They were avaliable a week before any of the others. But then the price was $1200+.
I personally bought a OEM E6600 on August 7th. The store, MicroCenter, only had four of them.

The problem being that even if it compiled cleanly, which isn't likely, it still may behave differently.

I not sure what distributions your are using, but the biggest users of ext3 are RHEL and Fedora, and they have had large file support for years.
I am pretty sure that ext3 fixed that with htree indexing. Htree has been around for a while.
