Why exactly are felons not allowed to vote? They're citizens like the rest of you, aren't they? What if the government deems your freedom fighting ways a felony and you're unable to vote them out of office?
Danish prison inmates are allowed to vote by letter like anyone else who are unable to make it to the voting booth.

I'm reasonably certain that you'd be safer in most of the offerings from a certain swedish brand of cars recently bought by Ford than you'd ever be in an Escalade.
SUVs don't make you safe, it only makes you bigger and gives you more kinetic energy to get rid of. Sure, it'll trump a 1980s Ford Escort, but that's not because an SUV is safe, it's because the Escort is shitty. http://www.euroncap.com/ runs a good testing program and you might note that a Toyota Prius gets a better safety rating than a Jeep Grand Cherokee.
Well, if you go through all that to make your PC into a router, you've just created a Juniper M160:) From your initial post, i was thinking "a motherboard full of PCIe slots and GigE NICs".
If you start making all these fun crossbar backplanes and line cards with on-board intelligence, you're 90% of the way to a dedicated router appliance and the OS part has been reduced to mostly keeping the hardware alive. This is exactly how a cisco or juniper box works, it just doesn't run Linux (although the juniper one does run FreeBSD;)). Many older and/or smaller Cisco boxes even use PCI as their backplane.
I don't see how you'd offload the work to a line card without putting some dedicated hardware on there, which would usually come in the form of an ASIC (or FPGA perhaps).
> I can see how you would expect different treatment on/. though.
I was quite certain people would kill me for not joining the "OMG It runs teh linux!!!1" crowd;)
And when your "zero-downtime failover cluster" gets a bug up its ass and the two nodes decide to battle it out for control over the virtual addresses, taking your network down?
It happens. For Cisco, HP and Sun too. The difference is, you can call them and bug them about it instead of hoping that the open source project people realize there's a problem and have time to fix it - or that you can fix it yourself.
They wouldn't leave it for nine months if they didn't have a workaround (set MTU to less than 1500). We've often received engineering builds from TAC to fix various problems and if the excrement hits the fan, you can have TAC work on your case 24/7, moving it between their three main TAC centers.
> That's not quite true. There's no reason I can think of why you couldn't make a backplane for a PC that handles all the network traffic locally, without touching the PCI bus (or whatever bus). In fact, high speed interconnects used on clusters do that sort of thing already, and I suspect any high speed backplane for any platform would need to do the same.
I think you're missing the point. The backplane of the Cat6500 is pretty much what the PCI bus does for a PC. A 32bit/33mhz PCI bus gives you just about 1 Gbps while the Cat6500 backplane provides three buses of 256, 32 and 4 Gbps (not 720 GBps as the GP suggested - the "Sup720" refers to the 720 Mpps switching capacity). Switching to PCIE gives you 2.5 Gbps per lane, but how many motherboards provide the 100 PCIE lanes needed to compete?
> I'm not intimately familiar with ASICs, but if they add this type of functionality regardless of the clockspeed on the core chip, they probably handle all the traffic locally too.
ASICs offload the hard work from the CPU of the Cisco systems. Basically any kind of compute-intensive bulk work, switching (yes, it switches layer 3 too), filtering (access-lists) and so on, is handled by dedicated ASICs and require little or no CPU intervention. This enables the catalyst to handle high amounts of data with a quite small CPU. Things that do end up on the CPU is management work, route computation (BGP changes, for example) and logging. To handle 720 million packets per second, you'd need quite a lot of CPU in your PC.
> A backplane like that may not exist for a PC currently, but if their PC router is successful enough to get companies using it, somebody will create one. Engineering a high speed backplane for arbitrary hardware is a problem that has already been solved, all that's needed now is a market with enough demand to make it worthwhile to build.
Well, large Juniper routers are run by a FreeBSD service processor, but i doubt you can run your open source router on it...:)
One thing the GP doesn't mention is the availability of special service modules, which one again do their work mostly in hardware: firewalls, load balancing, intrusion detection, intrusion protection, voice gateways, etc. Also, it takes 4 port 10GigE and 48 port GigE blades, giving it up to 48 10GigE or 576 GigE ports in a 13 blade chassis (one slot goes to the supervisor), something you'd have a hard time stuffing into a PC:)
With regard to ease of use, within 15 minutes of powering it on for the first time, most Cisco admins could have it up and running, switching and routing - IOS is a fantastic OS for most things.
Either way, i doubt the catalyst 6500 is the intended target for an open source routing platform and i'm sure it'll do just fine competing with the 2800-sized routers.
Actually, NNTP is a horribly ineffective way of moving binaries. Once you're done with the encoding, you're using about 50% more bandwidth than the size of the actual file. It also places a large load on the NNTP server - much more than serving the same files with, say, apache.
What you'll really want is an akamai-approach, but that way the studios can't hand off the costs to the ISPs like a bittorrent download does.
This is why the child pornography filters employed by most Danish ISPs now will only redirect the user to an "Oops, you do know that this stuff is illegal, right?" page.
Then again, our filters are made mostly to protect the innocent from being subjected to CP by accident (and yes, it'll stop a few from ever getting into the stuff), not so much prevent someone who really wants it from getting it - they'll always find a way...
Surely there's no downside to running, as opposed to biking? Yes, it uses a bit more energy, but it will improve the fitness of the runner (probably more so than biking will for you), and there's no real shortage of that sort of energy anyway.
Even if the OS was naturally resistant to various malware, it doesn't remove the biggest security hole of them all; the millions of clueless users (my parents included) who happily click on attachments and install fun shareware they get when they slap the dancing monkey in the banners.
Never underestimate the stupidity of users looking for an easy way to get more porn.
I usually assume that all car drivers are morons, all bicyclists are morons, all pedestrians are morons, all motorcyclists are morons and that i, myself, am a moron.
They would be much cheaper to keep running than the thousands of 73G and 146G drives many of us are using now.
One of them could easily replace the 30ish EMC systems current running here - with 75% space left over - and save a fortune on service and power. 256G of cache isn't something terribly impressive, though, as both EMC and HDS has had that option for many years.

Does it run FreeBSD?
It's also a five year old platform.

I wonder if i could sell a 4-digit
Oh boy... Low UIDs hardly instill authority!
Of course it does - we're better than them.
I'm amazed they don't just find the lawyers that are organizing the class action lawsuit and declare them terrorists and send 'em to Gitmo.

If you read the article, you'd know that it wasn't the DRM that was broken, but just the file system layout.
It does open up the stage for people who actually want to start working on breaking DRM.
