It seems that this cluster can run both windows and rhel4... I would like to see the comparative performance between the two OS's running on the same hardware, and configuration of each (ie is it 64bit redhat, windows hpc is 64bit only i believe).
You don't actually need cellphone service to make emergency calls... You can typically make such calls just from a handset without even a simcard, it will pick up the first available network, and the networks should all route emergency calls for free.
The spec would dictate functionality, not performance... The x86 instruction set is well defined, and implemented by multiple vendors, yet they don't all perform the same. Extensions to the instruction set come out from time to time, and are published, subsequently implemented by the other vendors and become part of the standard. New instructions are typically not used very widely until all the vendors have implemented them.
The trouble is, the existence of closed source drivers which are "good enough" for many people divert a lot of resources away from producing open drivers.
IF you can spoof mybank.com.au's DNS then you can apply for a certificate to that domain yourself... Most certificate authorities just send you an email to confirm, and if you control the DNS you can control the MX records to ensure you receive that mail.
It may not have been done many times that we know of, but i've not heard of DNS spoofing attacks for such sites either.
Your browser would not know the difference between the certificate for www.mybank.com.au owned by the bank and signed by CA1, and the certificate for www.mybank.com.au owned by evilhacker and signed by CA2. As for revocation, how exactly does your browser get to know that a particular cert is revoked?
What really should be done, especially in the case of banks where they are already in contact with their customers... The customer has to authenticate to the bank's webserver, but why shouldn't the webserver authenticate to the bank's customer? The way SSH works is good, the user has the public key of the host and verifies it each time they connect, the bank could supply you the public key when you sign up for online banking.
What I'm interested in, is seeing how this compares to a Linux based cluster using the same hardware... Last time i saw a windows cluster in the top500 list, it was 150 places behind a redhat cluster using the same hardware but with less nodes (around 5% less if i remember).
XP SP3 is considered an obsolete version of windows that is being phased out.... Good luck getting your 8 year old nvidia card working in vista.
To contrast that, i have a printer/scanner combo of similar age... It works with XP and OSX 10.4/PPC... The HP drivers don't work in Leopard either on PPC or x86, nor do they work with vista. There are open source drivers for this device that do work in the latest linux distros (this printer/scanner works out of the box on ubuntu 8.04). There are also no drivers for 64bit xp, but 64bit linux handles it just fine.
I can also use it on linux running on exotic hardware (sparc, mips, ia64, alpha, ppc) without issue, and there's no reason the drivers couldn't be ported to other platforms.
Closed source drivers limit what you can do... As we move to 64bit hardware, what happens to all those old devices which never had 64bit drivers written? What if IA64 had taken off instead of x86... What if those mips based laptops from china take off? What if i want to connect a printer to my phone or some other handheld device? I don't want to be at the mercy of hardware developers any more than i have to (ie inherent physical limitations of the hardware).
Yeah, HP really should provide HPLIP on the CD with the printer, and a link to the latest version, and mention linux support on the box... With the current crop of linux based mini laptops, it might help sale for printers and such like to explicitly advertise compatibility with linux.
The RadeonHD driver is relatively new, and the documentation from ATI has been coming out fairly slow (some of the 3d specs were only released a few weeks ago), all things considered the driver is coming along just fine. Aside from that, many linux users have been buying intel (open drivers) or nvidia (better drivers than ati's) cards... As radeonhd matures you can expect linux users to choose ati cards instead, which will serve to increase interest in the drivers.
An older example would be the Matrox video drivers, which were open sourced and ended up outperforming the windows drivers written by matrox quite considerably. To the point that Matrox cards using the open drivers were outperforming theoretically faster cards (with inferior drivers).
I haven't tried their windows drivers, but the mac ones were pretty bad. The open source ones on the other hand, really are just drivers that interface with cups and/or sane, and other than that pretty much just get out of your way. No stupid utility programs, no background services... Seeing as they're open source, if such user hostile functionality ever existed in them, someone would soon strip it out anyway.
I will however look at Brother printers, since someone pointed out they also make open source drivers available.
Why does hardware need to be so non standard and proprietary requiring its own drivers?
Take for example USB1, all USB controllers from many different manufacturers work with generic UHCI or OHCI drivers.
USB2 is even better, since all controllers support EHCI.
SATA potentially has AHCI, tho not all controllers support it.
Most CPUs have the x86 instruction set.
Video cards have VGA/SVGA/VESA, tho these specs are obviously far too old to be useful today.
Sound cards have soundblaster compatibility, and more recently AC97.
Proper modems have the Hayes command set, not counting some software modems.
Printers have postscript, tho typically only higher end printers support it.
If you have standards in hardware then the issue of drivers goes away... Your OS can provide drivers for the standard hardware, and thus not have third party driver code in the kernel... This would cure the Linux driver problem, and cure a majority of Windows crashes.
Then maybe the manufacturers should stop ripping their customers off like this...
Selling exactly the same card at twice the price? That's ridiculous... If they want to charge twice as much for a card, put twice as many shaders on it or whatever... Actually earn that money.
When it comes to buying printers, i typically look towards HP... They provide open source drivers for their printers and even the all in one printer/scanner combo devices.
Aside from HP i would consider postscript network printers, i recently had such a device from Samsung and it worked well.
I actively avoid Lexmark and Epson due to their lack of open drivers.
Incidentally, my old HP scanner/printer combo only works as a printer with OSX Leopard and Windows Vista due to the closed source drivers having not been ported. It works perfectly with an up to date Linux installation since it was possible to just recompile the drivers. On the other hand, i'm having major trouble using saned (network scanner support) with my macbook as a client to the linux print/scan server, local scanning on the linux box is flawless.
Game review sites/magazines these days are sponsored by the very companies producing the games they review... They rely on those companies to provide review copies (review items often differ from the actual item on sale), and rely on their advertising to keep their publications afloat. And if they become popular, they pressure games companies by threatening them with poor reviews if they don't get their freebies and advertising revenue. It all makes a very poor environment for creating unbiased reviews.
Perhaps the released version has onerous copy protection schemes which the pirated version does not, and thus the game would receive an even lower score when reviewed. It has been known for special "review copies" to be sent out with consumer hostile copy protection schemes removed so as not to attract a negative review.
What we need is a w3c site, like validator (validator.w3.org), but one which processes a given page and renders it according to standards, and produces an image of it.
No, what's good about Linux, and to a slightly lesser extend OSX, is that Unix is an incredibly simple system at it's core, so there are relatively few possible exploitation vectors and they are all well understood.
No, they just monitor it instead... You don't know if someone is doing something they shouldn't if you stop them from doing it... If you let them do it and keep watch, you can punish them for it later.
That's fine, China has sufficient population to fill the stadiums anyway. Expensive oil just means that only the rich will go, and they wont need to fight through crowds of "peasants" to get there.
The code seriously inconveniences me, it will be a very minor inconvenience, if that, to a thief...
The door lock on the other hand is a much greater inconvenience to a thief... He will need to try and pick the lock, or break the door down, which is likely to generate noise (for the neighbors to hear). It's much harder than simply walking in.
What's more likely to prevent the car radio being stolen is.... It's the factory fit, identical to thousands of others which are available in scrap yards. It's the factory fit and only fits this type of car, anyone who has use for this radio already has one. It's riveted and bolted in place, taking considerable work to remove (i know this because i had to take it out to get it recoded, had to take half the center console trim apart and drill rivets out).
Well, for me the cost of replacing the radio (with an identical one from a scrap car) is lower than the cost of recovering the code... The same radio was used on several different models over the space of over 10 years, there are plenty of them rusting away in scrap yards these days.
How can i set it not to demand the code again? There is nothing in the manual that explains how to do this. The radio is the factory fit on a 1995 Jaguar XJ12, not sure who made the actual unit.

Advfs is certainly a lot more mature, having been around on digital unix, later tru64, for many years...
