I once had an exercise in a business math class where half had calculators and the other had nothing. Calculator users *had* to use the calculator. The teacher then asked simple arithmetic questions - 2x2, 3 minus 1, etc. Of course, the people without calculators could answer first.
That shows that our fingers are slower than our brains. No surprise there.
The fastest computer in the world will always be limited to how quickly data may be fed to it. One way or another, a human will have to direct this operation - if only for safety and security considerations.
That's just silly. Computers can already prcess data much faster than you or I (or you and I) can follow.

That sounds like "Economies of scale, economies of scale, economies of scale". That wouldn't be bad if I hadn't mentioned economies of scale in my post.
Once the need for a service passes a given size, it's cheaper for a company to provide that service itself rather than outsource it. For large companies I'd guess that covers most services. For small companies maybe not.
Still, outsourced software provides real value in many cases, and companies want it dearly. For example, if you have any idea how expensive it is to pay IT staff simply to support MS Exchange for a medium to large-size company, the costs are huge. Several companies are currently making a living hosting Exchange, Oracle Financials, and other "hostable" commercial software packages because over time it is actually cheaper to pay someone else a flat monthly fee to manage it than to hire your own staff, especially if you are a large organization. Intermedia [intermedia.net] is one ISP I've seen that hosts Exchange, for example.
How can it be cheaper for you to to hire the staff than it is for me to hire the staff? We both need the same number of support staff to support my users. But now I have to pay for your proffit.
For small companies I can see where paying someone else to manage your email severs may be cheaper, but for a large company, where the need is large enough for economies of scale to kick in, I don't see how it is possible for you do do it cheaper and at a proffit.
Oh please. Can't you follow the topic? We were talking about the amount of time it took to get to 1ghz and then the smaller amout of time it took to get to 2 ghz.
The military has ALWAYS been the source of most technological innovation.
What are the three most important inventions of the last century? I'd list:
Automobile
microprocessor
Air Conditioning
None of these came from the military.
And then, you have to look at the cost of obtaining civillian advances via military projects.
Someday we may get civillian aircraft off-shoots of the Osprey (for example), but at what cost? They have been working on that thing for decades.
Justifying military projects with possible civillian off-shoots is absurd.
The first thing to do is take a look at the course for the two and see which ones seem most interesting to you.
Then take a look at some job listings, choose a few that seem interesting to you and see which degrees they require.
I have never seen a job listing that asked for a CIS degree that wouldn't accept a CS degree. But I have seen many interesting job postings that required a CS degree and would reject a CIS degree.
BTW, I don't have any degree and I'm not having trouble finding work. But I think I was lucky to begin with (it's easy to find work when you have experience, but hard to get experience without a degree).
In general a CIS course will teach you how do use something (database, OS, language, etc.) A CS couuse will teach you how to create that something.
Consider it a modern definition of an OS as well. Would we really want to separate the network functions from the basic OS these days? Should copy/paste functions be considered integral? How about Internet apps, or connectivity programs, calculators and simple text editors? Where is the line drawn?
While I agree with most of the reasoning in the brief, I don't agree that there is no good definition of an operating system. Pretty clearly the copy/past functions are part of the shell, not the OS. FTP and Telnet are utilities, not part of the OS.

Well, before Microsoft included a TCP/IP stack with Windows there was a thriving market for third party implimentations. Most of which were faster than Microsoft's.
You choose. Do you want all from one or best of breed?
Sorry, you can't choose. The third party market died when MS included the stack.
That's the problem the brief is trying to address.
Foo, the major problem with wireless Internet is that there is no content that is valuable on the tiny screens that most users have on their cell phones.
Perhaps, but I've worked where they went from several email systems to Exchange. Before there were no problems with email viruses. Most of the users were completely immune to them.
After the conversion email virus infections became a monthly event.
I don't care how well Exchange can be locked down after the fact, it has already cost them more in lost man hours than it can possibly save in productivity.
Are wiring diagrams for the Enigma rotors available? I have enough information to simulate an Enigma device, but I don't have enough to recreate an actual encoding.

C# is portable if you want to port it from one windows box to another. C & C++ are portable with a lot of work with the preprocessor.
When ypu've run the exact same Java on Windows and Unix then you know what portable is.

It's simple, the NSA is lying. You can't believe anything the spooks tell you, they lie for a living.
We didn't know anything before the show, and we still don't.
Oh please. Can't you follow the topic? We were talking about the amount of time it took to get to 1ghz and then the smaller amout of time it took to get to 2 ghz.
Do the math.
1.0ghz -> 2.0ghz is a 100% increase.
33mhz -> 950mhz is a 2700% increase.
IBM is a hardware company. They don't care what operating system you run as long as you run it on their hardware.
Sure they would be happy to drop AIX if (and only if) Linux became as good an option as AIX. So what? They'd run MS-DOS if that worked as well.

Wouldn't counter intelligence be a job for a national police force? Perhaps even counter terrorism.
And the advantage would be? Fiber is normally buried in the ground. Wireless uses antena towers that are very easy to get at.
