Amazingly enough, I _do_ use Linux. I also use FreeBSD and Windows. Linux has crashed on me several times, in 2.0.x, 2.2.x, and 2.4.x. FreeBSD has crashed on me in 2.2.6 and 3.0.
I was not claiming Linux was less stable than Windows. I was more concerned with an operating system that crashed for no apparent reason, and the apparent lack of concern for it.
These were pretty uninteresting - just sitting there watching the kernel compile. Except that at one point, while running the 2.4.13 kernel, the hard drive started grinding away with the drive light pegged on continuously, the display became extremely sluggish and quickly froze up entirely, and about ten minutes later, the hard drive light went off but the machine remained unresponsive, requiring a hard reboot. I don't think this was related to anything I was doing as I wasn't actually doing a compile run at the time - probably just a random occurance, but worth mentioning.
So the machine essentially BSoD'd, but it's not interesting?
The US courts have agreed that they ARE behaving in an anti-competitive manner. They just disagreed that breaking up the company was an appropriate remedy.
I worked for a VoIP company until recently. The product we were using was _significantly_ cheaper than a DMS, and would provide ALL the same facilities as a 250(at class 4 level). Total price for a box capable of 7392 DS0s: $1M. Significantly cheaper than a DMS 100 or 250. Note that you'd have to provide your own channel banks, but that's normal. IIRC(and I'm probably wrong), the 250 doesn't have loop capability, so you'd have that cost anyway.
The major problem with traditional telco is the single cable from the telephone to the switch, as well as the stupidity of the phone. MGCP/Megaco/SIP solve the stupidity problem, but don't resolve the one cable problem. At a higher level, SS7 is just plain stupid WRT routing and access. If interested, I'd be happy to elaborate on it.
As background, I used to work for a LD carrier. One of our customers did mass-calling.
The tones mentioned are commonly called a "tri-tone" message. They don't have to be there, so it's not a valid measure of a phone number working or not.
Most all mass-dialers use T1 or higher CAS(channel associated signaling) interfaces to dial out. When connecting a call at the T1 level, there are 2(4 on ESF systems) signaling bits, known as A and B bits. When the customer places a call, the first thing they do is set the A bit(s) high(to 1). Then various digit signaling happens, and the call is attempted via the carrier. If the phone number is valid and answred, the carrier sets the B bit(s) high. The customer now knows they have a valid phone number and a valid call, and will begin playing their spam. They never listen for a tri-tone message.
The other common way to dial out is via ISDN. The caller sends a connection request and receives a completion or error. They once again will not listen for a tri-tone.
I've never known a customer to pay attention to tri-tones.
Sure, the Replay doesn't have a subscription requirement. But how much you wanna bet there's going to be more intrusive information sent up that ethernet connection about your viewing habits?
While the glossy is definately light in details, this sounds like yet another(ok, probably the third or forth to actually work) SIP phone. I've used these devices before. The idea is good, but the two implementations I've seen that got even close to working were not up to snuff yet.
I don't know about the non-fiber portion of Cisco, but the last guy I talked to got $800 or so just for taking our call at 3am. This is on top of whatever they're being payed to answer the phone.
This company is right up the road from me. There was an article in the paper the other day saying they had to let people go and were having problems getting funding.
The funny thing is, until I saw that article in the paper, I'd drive by every day and try and figure out what the *hell* they could possibly sell: acryllic office furniture? Now I know.
Have you ever looked at an apartment contract? How about electricity/gas? I believe Time Warner even has a "we can enter your premises even if you aren't here" item in their TOS.
On the flipside, you have to consider Sprint's side. If you've got a tranceiver blowing up your entire area, what are they gonna do? Cut off your electricity? Build a giant EMF shield around your house?
My SoftSwitch running on a Sun Netra begs to differ with you on the "real-time, tight-to-the-hardware" statement. Note that the ANSI standard for SS7 calls for 56 or 64K links. Not exactly hard to keep up with, mind you.
A CO is a Central Office. It is were the wires go when they leave your house and head for the phone company. Most likely there is a CO closer to your home than the office you can "see." They're pretty easy to spot, as they are hardened for weather and civil unrest -- usually housed in a large building, maybe with a bill Bell logo on it(if it's pre-divestiture). Interestingly, just because you can get ISDN doesn't mean you can get DSL. ISDN can be repeated, DSL cannot(there's your useless fact for the day!)
Haven't you ever heard the "any portion of this broadcast may not be reproduced..." message towards the end of any pro sports game? MLB(Major League Baseball), et al can sue the rebroadcaster for the offense. This is similar to pay-per-view "events" held in many bars.
I hope they don't, that's how my employer stays in business...VOIP baby! It actually works really well. You'd be amazed how many carriers actually use it for overflow calls.
Here's my proposal: Make Microsoft release the source to all their products(Where disclosure agreements allow it). Use a modified GPL, where only Microsoft is allowed to distribute binaries compiled directly from those sources. In other words, everyone can see how it's done, only Microsoft can release "Windows." Everyone else gets to integrate MS code into their software, thus ensuring competition.
OK, boot messages are one thing. But here's a scenario for you: I write a really cool filesystem driver. To support its developement, Microsoft gives me $5000. They stipulate that I have to advertise that they supported it by inserting a "sponsored by Microsoft" message in the write() system call. When the message pops up(it's full-screen of course!), the kernel spinlocks for 15 seconds. This seems like the logical path for advertisements to take, at least from an advertiser's point of view. Force the user to see the message.
Actually, Quantum crypto relies on the only encryption algorithm proven to be unbreakable: one-time pad. The quantum channel is used only to create the pad. An unsecure link can be used to transmit the encoded message.
IIRC, the data laser doesn't lie in the visible range. It has a low-power visible light laser to aim with. We're actually thinking of using this product to bridge two buildings together where I work. I'll check and see if we've started evaling the product yet. It's much cheaper than the equivilant SONET equipment.
It's far more likely that China is blobking "everything" and allowing some things through. I work for a company that has several boxes in China. I have access to them only through a few sights that are specifically allowed through. If we add a management box, we have to phone up a guy in China and ask for it to be allowed through.

IMAP is a better protocol. Seriously. And it's just as open as POP[23]. For more info, see the RFC.
So now, just because MS likes a protocol, we're not allowed to like/use it?

In the directory, there's a 4.4-mini.iso. It's 184M. Is that small enough for you?
It most definately does. I use it at home with a Dell and two seperate Cardbus network cards.

The location of the bug cannot be determined.
This is by no means new, and has been covered on Slashdot before.
You can find out quite a bit about quantum encryption and cryptography at acm.org or any good library.
