I had a similar problem about a month ago. I solved it with BackupPC.
It's written in perl, open-source, runs on Linux. It can backup Windows and Linux clients. Windows clients don't need any special software on the client side, the backup is done using Windows sharing.
From the article:
The leading candidates for a possible congressional relocation are Charlotte and Memphis, both of which have long sought a major organization to raise their national profile. [...] Dallas, Seattle, and Toronto have also been mentioned as long shots.
The author says PowerMac G4 933MHz with a 60Gb hard drive, 256Mb of RAM, and a Super Drive (that's DVD and CD-RW people!). This is going to run me $2,299.00. At Dell's website (Dude, yer getting' a Dell) I can get a 1.8GHz Dimension with an 80Gb drive for $1,497.00. That's $800 dollars less for the same functionality, more hard drive space, twice the clock speed (I won't get into CPU architecture), and your required contribution to the Microsoft Empire in the form of Windows XP and Microsoft Works.
First, the superdrive is a DVD-R and CD-RW, it burns DVDs and CDs. The Dell doesn't have that, and guess what, it costs about 800$ to get one. The assembled-with-the-cheapest-possible-parts-PC doesn't have a warrantee, so it's not a fair comparaison.
Also, his whole argument about weither more MHz is better is quite stange. At first he says that only Joe Sixpack thinks that, and people who know computer architecture relalise that the MHz are only a part of a computer speed. Two lines later, he says that the Mac is slower because it has a lower frequency.
Let me tell you something, if you ever have two computers that have the same performances (time to do a task), always take the one with the lower frequency, you'll have a more stable system, it will produce less heat, etc.
Anyone contemplating objecting to CPCC's proposed statement must realize that the Copyright Act sets out a number of limits on what the Board may or may not do. No purpose is served by objecting to the proposed statement based on grounds about which the Board can do nothing. In the following paragraphs, we summarize some of the limits imposed on the Board's powers in this matter: (1) The Board must certify a tariff and set a levy. Those who own the rights to sound recordings of musical works (composers, authors, performers and producers) are entitled to be remunerated for private copies. No purpose is served by asking the Board to reject the tariff as a whole. (2) Only persons who own rights in sound recordings of musical works are entitled to share in the remuneration; owners of rights in other works (computer programs, movies, literary works) are not. (3) The remuneration must be paid by manufacturers and importers of blank audio recording media, in the form of a levy to be imposed on those media. The obligation to pay arises when the media are sold or otherwise disposed of in Canada by the manufacturer or importer. The Board cannot set the levy at the retail level. (4) The levy is payable on all media that qualify, without regard to end use. No purpose is served by asking that the tariff include a mechanism that would allow those who can prove that they use qualifying media for purposes other than reproducing musical works to be exempted from payment or to receive a refund. (5) The Copyright Act exempts from the levy recording media that are sold to a society, association or corporation that represents persons with perceptual disabilities. The Copyright Board cannot grant any other exemption.

Of course, if you were a little more thorough:
Dimension 4400
-- 2.0GHz P4 (should run circles around a 1GHz G4)
-- 512M DDR RAM
-- 80G ATA/100 (Mac only has ATA/66)
-- DVD-RW/CR-RW
-- 1yr warranty (Mac is only 90 days)
-- No monitor
-- Software options (ie Office) removed
-- GF3Ti200 (probably about equal to a GF4MX)
-- 56k winmodem
-- 10/100 NIC
$1,882
If you were a little more thorough, you'd have realised that he was talking about a dual processor! A 2 GHz P4 is NOT equivalent to two 1 GHz G4.
Don't get me wrong, I'm a Mac Lover, I'm writing this on a Mac G3, and I'll buy a G4 (or G5) this summer, but this is really dumb:
Shorter data pipeline
The performance advantage of the PowerPC G4 starts with its data pipeline. The term "processor pipeline" refers to the number of processing steps, or stages, it takes to accomplish a task. The fewer the steps, the shorter -- and more efficient -- the pipeline. Thanks to its efficient 7-stage design (versus 20 stages for the Pentium 4 processor) the G4 processor can accomplish a task with 13 fewer steps than the PC. You do the math.
That's really FUD, a longer pipeline is better, the Pentium4 can start 20 instructions before the first one is finished, while the G4 can only do 7. The G4 is faster than the P4 for other reasons.
SGML is the ISO standard for stocking information, and Docbook is the standard for writing books/documentation in SGML or XML. IMHO, it's the way to go.
I agree 100% with you, and I'm thinking specifically of Usenet. I can imagine a Usenet where everyone has a certificate signed by a trusted authority, or signed by someone who was signed by a trusted authority.
I think that this is a great idea, but I don't see how it would be managed? Would the thrusted authorities sign the certificates for free or for a charge? If they charge something for the signing, the number of people on usenet would drop. And if this is free, how could any kind of verification of the authentity be made?
Also you would loose a lot of Usenet's privacy, since everything is signed by the sender. The evil-corporation/NSA/Ashcroft/MPAA could prove that you send a specific usenet message and beat you with a big stick.
But I agree that it would help a lot in making usenet a bit like it was in the pre-1995 era -- that is, before I discovered usenet... 8)
okay, let's say we allow backdoors in crypto devices:
1) Bin Laden & co. will continue to use their own RSA implementations.
2) All !US compagnies will continue to use non backdoored implementations.
3) US compagnies will use backdoored implementations.
4) !US Intelligences agencies will find out the backdoor key
5) US compagnies will start loosing international contracts because !US compagnies get to know their secrets
6) US just shot itseft in the foot.
As for the complete ban of cryptography, it's so dumb, I don't know what to say. The FBI will raid my house because I have a floppy with Netscape 1.1 (with SSL) at home? E-Commerce will stop? I guess this was proposed by people who don't know what cryptography means...
Am I the only one beleiving that the NSA is actually able to break RSA?
Think about it:
1) The only role of the NSA is working with cryptography, and help the CIA deal with crypto.
2) The NSA is the institution that hire the biggest number of mathematicians in the world (that's a lot of brains!)
3) The NSA has been receiving requests from the CIA to break RSA for what, 20 years?
I'm not saying that they can decrypt RSA in real time, but when looking at the past, the British secret services were breaking Enigma every day when everyone was absolutely sure this was unbreakable (heck, they invented the computer!). I'm pretty sure that 20 years from now, we'll learn that in the 2000's the NSA was able to break a RSA encrypted message in a few days.
That would also help Echelon make a lot more sense; Echelon without a RSA breaking technique is much like a car with flat tires; it works but it's pretty lame.
Here's a french translation of their Sample Letter, so that Québécois don't have to translate it again.
Subject: Réforme sur les droits d'auteurs
Je vous écris pour vous exprimer mes craintes face aux mesures extrèmes contenues dans les documents de consultation sur les questions ayant trait au droits d'auteur sur Internet (DCQDAI).
Ces mesures, inspirées du Digital Millennium Copyright Act (DMCA) américain, donnent beaucoup trop de pouvoir aux producteurs par rapport aux citoyens. En fait, le DMCA est déjà remis en question aux États-Unis, car il a été utilisé pour censurer la publication de recherches universitaires. À travers le monde, les chercheurs en sécurité informatique refusent de présenter les résultats de leurs recherches aux États-Unis par peur de représailles criminelles, comme il est arrivé au programmeur russe Dmitry Sklyarov. Sklyarov a été arrêté par le FBI pour avoir présenté le résultat de ces recherches sur la sécurité des livres électroniques (eBook). Ces mesures, ne servent que les intérêts des corporations américaines, et ne peuvent que nuire au canadiens.
Ces mesures ammenderaient la Loi sur le droit d'auteur dans le but de banir la quasi totalité des logiciels et autres outils qui permettent de surmonter les technologies de prévention de la copie. Ce qui rendrait la Loi sur le droit d'auteur en violation avec la Charte Canadienne des droits de la personne, et du même coup la déclaration universelle des droits de l'homme de ONU, car ces outils sont nécessaire à l'exercise des lois sur le droit d'auteur et au visionnement des produits protégés par les droits d'auteurs pour les personne ayant un handicape visuel ou auditif.
Je vous demande donc d'enlever ces mesures controversées et discriminatoires du texte du DCQDAI. Le DMCA est déjà un échec international; il ne devrait pas être importé au Canada.

A couple of months ago, they were all crying: "Come on NS release your browser now! We can't wait, you'll lose everything if you don't." Netscape decided to hurry up in the process, yes some bugs are marked rtm-, but this doesn't mean that this won't be in the RTM, this means that this is not top priority for RTM.
This means that at worst these bugs will be corrected in Netscape 6.1. Hey they start to listen to you, they start to behave like M$!
