Aren't you aware that copper also has limits on the radius you can bend it, based on the thickness of the bundle? You can damage copper by bending it, too.
I didn't think that Qwest was a CLEC anymore. Its main biz seems to be as an ILEC. Remember that it bought uswest, and then got Borg'd by it.

Good starter article, maybe

Understanding NFS
·
· Score: 2, Informative
I don't think this article qualifies as "understanding nfs". NFS is a hairy beast, and all this does is get you started from the userland point of view. What makes nfs so hairy is the numerous ways it can fail or at least not do what you expect.
I hate to enter the language debates, but here goes.
Smalltalk is nice - I like the language, and have had some fun being diverted by squeak - an environment I'm going to return to when I have more time.
However, even smalltalk is limited in how you can manipulate the language compared to the insanely cool things you can do in Common Lisp. Different people have different LISP expereinces, and mine are far from completely positive (I hate the common lisp builtin names - I much prefer scheme's!) but its the only environment I know of where all of the above buzzwords can co-exist, and have since the mid-80's before the buzzwords were mostly invented.
Object-oriented? CLOS, check.
Multiple-inheritence? With CLOS, check.
Intuitive GUI? Well, there's emacs and there's different IDEs, which I'm not familiar with. So a "maybe", coupled with the ominous "so what do you consider intuitive?" The IDE screenshots at www.franz.com for their Allegro CL doesn't make it look too painful. As long as there's a good class browseer, ala squeak, syntax highlighting and indentation, and good build tools and workflow tools, you're mostly there.
Full support for operator and function overloading? Oh yeah, you can re-define everything. CLOS' is very cool for the control it gives you in function overloading, too.
Portable? Depends on what platforms you're porting to. Windows and unix, definetely.
Anyway, its something you may want to consider, since if your boss really doesn't have a clue what he wants, he's probably going to get either Smalltalk or Common LISP with that list of requirements. So if he wants something, he'd better come out and say it before he finds himself cutting a check to franz for a copy of Allegr CL!
Nah, communism did that for itself. Come on - Marx wrote books to pay for his kids education, travel, etc. then on to Lenin, Stalin, and everything that made russia what it is today (which is: not a communist country).
Communism is a really interesting idea, and a very noble set of ideals. But what it comes down to is controlling people, and all it takes when you have power is one person to use it and all those lofty goals are subverted.
Final note: in business or in government, don't trust 5 year plans that don't have month-by-month goals. 'Cause no-one can procrastinate that much and still do the work.
As someone who has taken on the job of adding to a small, not often used, but personally very interesting driver, here's the advice I have:
1) Get used to rebooting a lot. You're better off if you can do this on a system that's not your main workstation, so you can, you know, still get work done.
2) Appreciate and treat very well anyone, I mean anyone, who gives you any useful advice at all. Because every little bit counts.
Amen brother. Its very common that when someone who has to justify the budget sees the price tag for even minimal security (a firewall and IDS between front end servers and database, and an OOB network to control firewall and IDS, plus a 3rd party audit on the code being run) they say "Nah. its secure. Someone told me it was secure enough. Go do something else now."
With a monopoly the rules are different because the reach of the monopolist is greater. One of the proposed remedies (sadly, not to be implemented) in the DOJ antitrust trial would end preferrential pricing, because of the vast leverage they have in making everything cheaper.
For instance, in the situation of the Australian brokerage, the pricing discounts given could easily have extended to a letter of credit towards all other M$ software for the next 2 years, on windows, or other deals that can't be offered by other vendors (that's what makes this made-up scenario an example of being anti-competative).
The above is just conjecture, but its not impossible, or even unlikely. But we don't know, because we won't ever see the contract.
This is debatable. The mainline netbsd may deal with many more, but its not like it's 5 or 10 times more afaik. AFAIK both the linux and netbsd kernels have been ported to most embdedded controllers, many makes of cel phones, networking gear, etc.
Don't be too dissapointed, its happened before. The release of 2.0 had massive issues, and almost daily patches to bring it stable. I still recall installing a kernel that caused apache to trigger an oops.
The swap has to be somewhere, and on critical systems you should mirror the swap, and it should be fast. So no matter where you put it (2 external raids, 2 internal disks, 2 silicon disks, whatever) you incurr a high cost for the additional and mostly useless swap space.
Haven't you heard of switches and VLAN's? You can overcome the issues you mention using moderately priced switches (assuming you're buying extreme or HP or Foundry, and not Cisco) and some not-too imaginative network configurations.
If you really need extra inter-segment security, throw in a transparent bridging linux firewall between segments and you've got a pretty tight setup.
<i>What most people seem to forget is that while Bush didn't see combat, he was trained in it.</i>
My recollection from pre-election rerporting is that Bush just decided to stop going to his training flights and his dad sheltered him. That doesn't seem like adequate preparation for a war.
So I'll join the crowd that's pinning its hopes on Powell.
The options presented above were "win or pull out". We've certianly not won the war in iraq, and we have pulled out. So you haven't really challenged the assertion, you've just blown off steam uselessly.
Many of us in New York would love to donate blood or otherwise help in any way possible, but this is apparently difficult right now.
The red cross does not seem to have anywhere I can donate blood in my area, so if anyone knows of any other resources that can use help from those of us sitting at home, wondering what we can do, please post links, phone numbers, whatever.
You'll notice that a lot of those debts are in the form of future business revenue that hasn't been realized yet. These won't be met if they go out of business. If those numbers are real, then many of those creditors still have an incentive to keep things running.

Actually, version 0.99pl11 and above ran pretty well. After that, 1.0 and above did what it promised. Quite a bit different from NT at the same time.

P.S. CLOS is the Common Lisp Object System
Quite impressive.

I can't find one of these on pricewatch, so its still vaporware.

Overcommit is an option.
/proc/sys/vm/overcommit_memory
Try:
$ cat
The default is 0 now, which means no overcommit. So its at the users discretion.

Right, but I got 200+k/sec with a ricochet setup in front of a crowd here at a NYLUG presentation.
It is amazing. I really hope it survives as it has more then made back the money I've put into it on my consulting gigs.

Yes, but the ricochet doo-hickeys get a couple of miles normally in a city.
