All you have to do, is in the words of the BOFH - is to get DUMMY MODE ON. Then the luser will agree to pretty much anything. I thought BOFH was merely extreme fictional parody when I read it as a student. When I got into the real work world, it was shocking to find that it wasn't that far from the truth.
Actually, the MPAA (or whatever their British equivalent would be) *have* learned from the music industry. Instead of gouging on price for older releases, you can get DVDs of some very good films for 5.99 in a store - about 1/3rd of the price of a CD. For that price I won't even bother looking for a download even if it's free since it's worth it to have the physical disk.
Nitpick: you are thinking of asymmetric not asynchronous connections. Asymmetric is where download/upload speeds are not the same. Symmetric is where upload/download is the same. A symmetric connection can be asynchronous.
What sarcasm? There was none meant. I was expressing that it's genuinely a real shame if the quality of the excellent PowerBook has gone to the pits. Or don't you agree?
It couldn't have happened to a nicer bunch of charlatans^W people. Why people are so supportive of Kazaa, an ad/spyware peddler, I don't know. It's also obvious their business is built on copyright infringement.
That's a real shame. I bought a 12in PowerBook last year and it's by far the best laptop I've ever used. Not to mention the best looking laptop I've ever used.
For my uses for my Internet server, Xen has proven an _order of magnitude_ better performing than UML, although there were some other changes that helped (going from file-backed filesystems to partitions for each Xen domain). But even without that, in practise, in most every day loads, the performance overhead of Xen compared to native is only around 2%, where the overhead of UML+skas3 is greater than 50%.
The Xen website has a performance comparison which has been independently verified. Xen has also been compared against IBM's mainframe virtualization.
The A in PABX is redundant and most people no longer use it. They used to be called PABXs to differentiate them from manual switchboards. However, no one uses manual switchboards now so hardly anyone calls them PABXs any more because the A is assumed.

Not as impressive as the 10,000 line PBXs (or PABXs as they were called then - Private Automatic Branch Exchange - to differentiate them from the ones where a telephonist would manually route your calls on a switchboard) of the last generation.
The previous generation was massively electromechanical - many many Strowger switches consisiting of relays, uniselectors and bi-directional selectors. The racket of thousands of relays moving and switches stepping must have been quite impressive. One of my co-workers is a former telephone engineer who used to work on this kind of kit for a telco. It took 20 engineers to keep a 10,000 line exchange unit operational. One engineer can now look after 6 10,000 line digital exchanges. He told me about one evening how he was on shift, in the exchange (a telco exchange rather than a PABX), and all was quiet. Then at 8pm, the sound started - all the switches started operating and the noise moved across the exchange, until it became a crechendo of noise. The cause? No, not World War 3 starting, but a soap opera having a dramatic ending on TV.
Some trivia: PBXs used to be known as PABXs, when it was new and highly advanced for a company to have a private AUTOMATIC branch exchange, rather than one where a switchboard operator would plug plugs into the right holes to manually route calls. The original PABXs were electromechanical - some large companies had Strowger private exchanges the size of a typical telco exchange unit.
I'm fortunate that the games I like are all running on native Linux - things like Doom3, Unreal Tourney, Enemy Territory (actually, it's ET I play the most, I enjoy the team-based online games). It's doubly fortunate since I don't have Windows.
ET also has a great mod - True Combat Elite - which is a complete mod of the game in the vein of Counterstrike. TCE is a bit more 'serious' than ET is - it's less cartooney and much more strategic (and a good set of headphones is helpful because sound is more important than ever). Both ET and the TCE mod are free. You can get them from http://www.truecombat.com/
I don't own a TV and regularly get letters from TV Licensing. I don't think they are threatening at all. I find them mildly amusing. Of course, it helps I live outside of the UK and the last time TV Licensing came, they got turned back at the port for not having work permits.
I really want them to visit so I can look in the detector van. I suspect it's an empty van with a list of households that don't have a TV license on a clip board.
But you still can't drink if you're in drafting^W selective service age. They shouldn't have it both ways; either you can drink at 18 or you don't have to register for selective service until you're 21.
A blanket license on computers instead of TVs seems a bit silly.
What they can do is this. Keep the TV license as it stands. However, if you want to watch BBC TV content on the Internet, you must log into the BBC website, providing your TV license details. This shows you have a TV license, and then you can go and watch BBC TV on the Internet.
This means people with TVs only are paying and people with no TV but a computer and broadband get to support the BBC too if they are using BBC content. And people with both a TV and a computer don't end up paying twice since they supply their TV license details to the BBC website when creating their account.
Actually, it's not collected from anyone who purchases a TV or radio. It is collected from anyone who _uses_ a TV. It's perfectly possible to buy a TV (say, to use in a training room at work) without a TV license. Also, the radio license disappeared decades ago. I don't have a TV but I do listen to the radio - but I don't have to pay a license fee.
It's part of the reason I haven't bothered installing a TV in my house - there are just so many pointless soaps on. I wish EastEnders had an 'off season' much like good tv programmes on - say, EastEnders was only shown once a week for 3 months per year.
BBC Radio on the other hand is second to none. There's always something interesting to listen to on the radio (well, with the exception of Radio 1 which is mostly bubblegum). It's even better now with the new digital channels. Sadly, I don't think we will have DAB in my area for decades, but I can at least get them over the internet.
I suspect the TV detector vans were nothing more than a van and a guy with a list of addresses without a TV license.
I don't have a TV license (I don't have a TV - not even an antenna), and I'm gleefully waiting for the detector van to turn up - so I can have a look inside.
Palm pilots, iPods et al. are not really in the domain of the kernel developers - they are all strictly userland issues. So it would be up to distro makers and people writing KDE/Gnome programs to interface with things like palm pilots or iPods.
USB 'plug and play' (USB hotplug) has been supported and has been working for years. I've never had a problem with USB devices where there's been a program to use them (or a driver, for example USB mass storage).
My response was really pointing out that the author was incorrect in saying that Xen had a high overhead - it does not - its overhead is incredibly low.
Xen can also use copy-on-write (and UML can too) filesystems for the common stuff between operating systems (so if you have five identical Xen domains, they can all mount the same copy-on-write fileystem), so you don't need five installs of the same OS.
Personally, I don't think Xen (or UML) and Solaris zones are really comparable - they are different tools for different jobs (the real comparison would be between Solaris zones and FreeBSD jails). My contention is merely that it's inaccurate to say Xen has a high overhead because it doesn't. Also, the characterization of the way Xen works (i.e. a host Linux with guest domains) was also incorrect since all domains running under Xen are run by the small Xen kernel rather than a large Linux kernel. (Indeed, domain0 can be NetBSD, and the domU can be Linux if you so desire).
Actually...if Solaris does get open sourced, wouldn't it be nice to have a Xenised Solaris?
TFA says that unlike Xen and UML, Zones have a very small overhead.
This isn't quite accurate - Xen does NOT have a large performance penalty (UML does, especially for I/O intensive workloads). Xen domains have almost the same performance as the native OS. Additionally, Xen VMs are not Linux kernels housed in a Linux host machine like UML, every Xen domain including domain0 runs under Xen itself. The only special thing about domain0 is that Xen passes off hardware access to domain0 rather than implementing all the device drivers itself.
Xen is more like IBM's mainframe logical partitions (LPARs) than UML or Solaris's zones or BSD jails. It serves a different purpose to zones or BSD jails (but a similar purpose to UML).
And Xen has very very good performance. I've been testing it recently and it blows away any other virtualization tools I've used on x86 including VMWare and UML.

Especially since 'expert' often means 'ex' as in former, and 'spurt' as in drip under pressure.
They are too dead to consider themselves anything, let alone lucky or unlucky. What kind of an idiotic post was that?

I wonder when OpenBSD 'pf' will normalize the tcp timestamp on packets passing through an OpenBSD firewall. Probably with OpenBSD 3.7 no doubt.
