Our server environment previously consisted of about seven RS/6000s running AIX and a dozen NT/2K boxes scattered about.
We ran our first secret linux box in 2001, which was promptly replaced with an expensive BSD box less than 12 months later. We also had a secret Windows server, but that too was replaced this summer with another BSD box, skipping the linux step entirely.
In both cases, our vendor was more than happy to support well understood BSD versus the (at the time) more quickly evolving linux distributions. Since then, the number of Windows Server (2000 and 2003) installations in our building has increased five-fold (serving about 10,000 internal clients), we've done half a dozen OS X Server installs on core servers (~15,000 remote users per day), and I think someone has set up a rogue linux box in the south wing to serve internal forums or something fun like that.
As for browsers, we have IE, Moz, Opera, FireFox and Safari installed on Mac and Windows workstations. Given the choice, most people seem to use IE on both platforms, followed by Moz (although less and less as Thunderbird gets deployed).
If all I'm after is Internet access not tracable to me directly, I wouldn't need higher level access, just access at all. If I wanted to do something particularly nasty, I would want to do it from a source that looks just like every other source (your 98 per cent) rather than from the easily identifiable two per cent of "higher level" accounts in the subnet.

What really bugs me is the steady diet of junk science we get from the tree-hugger crowd these days. Take this article, for instance... it's a logical fallacy to assume that since there may or may not have been an ice age in the distant past, this automatically implies that we are about to have another one, or that we'll all bake to death due to global warming.
Here's an interesting article [predictweather.com] that gives a common-sense approach to understanding the reality about climate changes, from a sound scientific standpoint.
Oops, I just broke a rule... I just stated that the emperor has no clothes!
The most fascinating part about many of these arguments is that climate change should somehow be stopped (or the implication that it is stoppable by humans at all!). Climate change should no more be stopped than the ocean's currents.
For some reason, it has become easy to ignore that our environment naturally changes over geologic time (ice ages), during a year (seasons) and during the day (day/night). To say that we should outright stop climate change is to suggest that we have the ability and authority to arrest processes that have occurred for hundreds of millions of years without our influence. To put the earth at equilibrium would be a crime against nature far worse than the grossest perturbation of the atmosphere that can be alleged.
with melted polar ice caps, massive species extinctions, and catastrophic climatic change.
There is more evidence to suggest that such events occur naturally and periodically than there is to suggest that humans are the direct cause. The earth has undergone many ice ages, each of which caused massive species extinctions by virtue of catastrophic (to the non-adapting critters) climate change. But that's not to say that humans can't cause climate change, we just have fewer data linking us to climate change than we do for well-established natural causes.
this is a global warming right now, direct temperature measuring evidence is rather hard to disprove
And humans are necessarily responsible for any increase in temperature why?
Bear in mind that humans have only been part of the last few (two?) ice ages on this planet. What caused or contributed to the global warming to get us out of the ice age 25,000 years ago? Internal combustion engines certainly were not a contributing factor!
Two piles: Local in scope, interoperability with other nations desirable but not essential: Indoor plumbing - Locally regulated by officials and industry The electric light - Electricity is regionally regulated by officials and industry who are tied to the same grid. Light bulbs may meet standards set by UL, CSA and analogous bodies. Or not. The internal combustion engine - Voluntary international standards and professional bodies try for interoperability. Not regulated except as found in other regulated items (cars, aircraft).
International in scope, interoperability required for public safety or interest: The telephone - ITU (or someone) must set international standards for this to work. The jetliner - IATA (or someone) must set international standards for this to be useful and not harmful. Hobby (personal or state) aircraft nationally regulated.
None of these technologies appears to be hampered in their innovation by any pattern of regulatory influence, elected or otherwise.
I think his point was that TCO != f(users,license), and is substantially more complicated.
- Cultures. Hmmm, you're going to have to show me how cultural factors affect TCO from one vendor vs another. I'm not saying it isn't so but it does sound like you are flailing.
You've obviously never worked at a serious institutional help-desk. A desktop image rolled out to a front desk in Legal can cost much more to support than the same image on a front desk in Marketing because of different expectations of timeliness in those two different corporate cultures.
Compare the willingness of users in Minsk vs. users in Tucson to wait for IT. Generally, in areas where the physical infrastructure is shoddy, users are more willing to wait.
Also compare the willingness of vendors and buyers to haggle. In many Asian cultures, doing so is a way of life; less so in North America. I'll leave it to you to figure out how the ability to alter prices, and the time that process consumes, could affect TCO.
Note that none of these items are tied to FOSS or any other licensing scheme in particular.
- Timezones. Yep, you're flailing. Did you actually give this the slightest moment's thought?
Your helpdesk is not necessarily in the same timezone as you are! Staffing 50 desks in Canada is considerably cheaper than 50 desks in Liverpool, but during what time of day do your users in Brussels need tech support? If your vendor is headquartered in and ships from Palo Alto and you need a replacement foo ASAP in Brasilia, the shipping (vs. sending foo to Seattle, for example) will cost more for logistics, uptime, and business processes. What if your vendor only has a fully staffed helpdesk open 9-5 EST, and you're in GMT+11? Again, factors untied to FOSS or any other licensing scheme.

Assuming that the distance between the bulldozer and the surface anomoly site is 100m, if this were a projectile, it would be moving at about 2 kilometres per second.
Note that the flight path appears slightly parabolic (bulges up), indicating that some non-gravity acceleration is involved.
Also, why are we assuming that this projectile originated from the sky and not from under the water?

Don't knock it. I just had 760E shipped to England for use as a student machine. Except for the lack of on-board USB, the thing blazes with Win98/2K, does wireless networking, and can be used to beat small animals (much like their Model M keyboards).

This won't replace the majority of sound or video editing uses due to hardware decoding/timing/response issues unless there's some wicked interface to the DSP/decoders on the PC hardware.
This won't replace print workstations since most of the the Adobe, Macromedia and Quark stacks run as well on PC as on Mac (some non-linear editing apps aren't dual-platform, but those don't really matter to print).
This may touch the education market if the OS X interface is a priority, but Windows XP or any XWM that supports themes would be cheaper.
This might be useful for cross-platform developers, but testing anything other than presentation should be done on real hardware anyway.
Still, this may be useful for not carrying two different laptops around to support MS Access and hypercard...
The lack of legacy PS/2 ports on the Mac would pose a problem, but KVM/IP or KVM/USB work fine.
iPhoto... is not useful for storing a digital photo album
Indeed. Real photographers use a 3rd party CMS/workflow solution anyway, while there are cuter solutions from Adobe and anyone else for consumers.

Autometic network printer discovery makes things easy. It begs you do do it the first time you print.
As far as the hardware itself, as I said it looks nice, but it's cheaply made
They come off the same production lines as many commodity PC laptops, so yes, they are cheaply made. But, unless you are using a PowerBook where you should be using a hardened unit, this isn't normally a problem for end users.
you have to snap off 4 of the function keys to get at screws just to start
The keyboard peels back as a unit by pressing two tabs. The structural screws are under the detachable keyboard itself, and on the lower chasis (you would know this if you're as good at servicing things as you later claim).
or $30 each if you try on your own
Not a user-servicable part unless you want to void warranty. Not a part that needs servicing unless you are attempting repairs in the field that should be done at the factory.
except for 2 design flaws
Please, fail to elaborate on this point when you criticise everything else in such detail...
Just like PCs, except that storage costs and speeds don't scale up quite the same way. A 50MP image will produce something like 60MB+ worth of sensor data or 10MB worth of JPEG per image. Transfering such from the sensor to the card, and from the card to a computer would require some hefty incrimental technology upgrades for speed. Shooting a four-shot burst in one second would require on-camera bus speeds of 4*60 MB*8 bits/Byte=2 gigabits per second (and a quarter gigabyte of cache before the CF card).
For comparison, a Sun e10k does 12.8 Gb/s on its Gigaplane interconnect...
In communications, there are more protocol issues to worry about. For modems, there's baud--the number of changes in sound per second (handwaving), the bitrate--each change in sound can represent more than one bit, compression--for example, e-mail and HTML don't often need more than 7 bits to represent its highly non-random content and can be compressed, bits for error-detection/correction--because there is always line noise, etc. so any given byte in a communication may take 6-12 bits (handwaving) to transmit.
Ethernet, token ring, and almost all other networks similarly add overhead to data in the form of headers describing the contents of packets which encapsulate user or application data.
Plus, your data is probably encapsulated in some kind of protocol (SLIP, PPP, IP, TCP, UDP, etc...) which add their own headers and other structure to your data. Individual applications usually need their own headers (content-type/HTTP negotiation for your web browser, SSL, etc), adding more overhead.
And of course, at each part of the communication stack, headers can be added or removed, packets repackaged and possibly reordered, etc. depending on what you are connecting to (the TCP/IP stack for an uplink is very special compared to the one in your Linksys). A poorly written TCP/IP stack in the OS does worse than a good one on the same network and network card (let's ignore PCI bus latency and software modems in the client machine).
In short, pulsing a piece of wire or a fiber x times a second can have very little to the actual data transfer rate as experienced by the user, hence data-link bitrate doesn't translate into experienced bitrate in a particularly quantitative sense. On a wired connection, it is generally safe (handwaving) to assume that it takes 10-15 bits of physical layer to transmit a byte of user data for many applications.
ATI Radeon 7000/32 on an Athlon 2500/512 gives me 1.3 (one point three) frames per second with one monster/NPC on screen. The communications tech guy and his friend almost killed me before I started shooting. With just walls, it feels more like 8 fps.
Isopropyl alcohol (CH3-[CHOH]-CH3)and ethanol (CH3-CH2-OH) are both light chain alcohols where the -OH group coveys enough hydrophylic properties to the molecule that it mixes well with water. That same -OH group on an alcohol like CH3-[CH2]12-CH2-OH doesn't overcome the hydrophobic qualities of the rest of the molecule, and will not cause it to mix well with water.
(heavy crude)-OH is an alcohol too, and that obviously doesn't mix well with water.
