As mentioned above - for a general purpose OS - you have to take priority into account. I can keep a machine at 100% CPU utilization - and it will have 99+% available to anyone that comes along with a higher priority.
What are those priorities, Interupt handling, high priority applications, ???
What this person might be considering is some kind of batch job scheduling environment - where you want to schedule an incoming job on the system with the greatest current capacity to process it. ie. using free resources around the network to do useful work.
Well, first off - it is CPU available above a certain priority. I may be running a 100% cpu usage process at a very low priority - so there is no "left over" cpu to utilize, but an application can come in and get 100% of the CPU.
I am not even sure there is a way of measuring what you want. There are so many variables (Disk I/O, memory bandwidth, etc.) that you can't get a reasonable measurement of how much CPU is left over to do useful work for your process.
The other thing is that many things can take down a CPU as well - a huge burst of network traffic can take an "idle" CPU and peg it at 100% in kernal usage.
Your best bet would probably be to hook into the various schedulers and get deep knowledge of what is really going on - pain in the butt, but doable
And what is stopping them from pointing the DNS entry for www.hackiis6.com to something like 207.46.20.30 instead of 66.133.110.84 ?
Would be a really fun site to watch being exploited, and when I was done say Oppps, someone hacked my DNS server, sorry about that - it is beyond my control... those naughty naughty hackers
Companies are now legally required to publically disclose breaches... 5 years ago there was no such requirement - so they didn't bother.
That said - the cracker population is getting significantly more sophisticated with more resources available to them (think a zombie network for solving distributed problems rather than simply launching a DDoS).
That would be like me annoucing on Dec 24th, 2006 that my company, Longhorn Computers, is suing Microsoft to cease and desist from sales of Windows Longhorn. I (and everyone else) knows that Microsoft has called it Longhorn for who know s how long... its unfair to last minute try to torpedo Microsoft.
Not quite - first off, I will place a bet today that Microsoft will never market an operating system named Longhorn. Much like they have never marketed operating systems called Chicago, Memphis, Cairo, etc. It will be called something like Windows 2007, Windows Advanced, ???.
Apples mistake is trying to take advantage of the "code name" and tie it to a marketted release. Tiger wouldn't have a leg to stand on if Apple simply released OS X 10.4 (or what ever the official name is) and let the trade press report the tiger name.
Apple really can't get their codename strategy in order - why is it that only apple seems to have these problems and not companies like AMD (The Athlon toilet partitions) - Intel (love the Cease and Desist orders on the Merced project) - Microsoft (pick your favorite city here)
While it is an interesting excersize - it is far from prime time. First you have the overhead of extra packet scheduling (and making sure that each RSVP'd stream stays within its reservation) - then there is the whole problem of what to do with packets that fall outside the reservation. Lets not even get into the policy questions on how a router decides if a reservation should be honored or not (much less who to charge for the bandwidth commitment)
All in all - over provisioning is still your friend
DUAL PCIe x16 with FULL SPEED x16 lanes... no, those are PCI-X slots, not PCIe.
Try again. Those are dual PCI-Express x16 slots. You will notice 3 chips on the motherboard (well, you didn't since you obviously didn't go to the website where these claims are made in plain english - with a picture that shows the slots as well) - two chips are HT-PCI express chipsets, the 3rd is a HT-legacy chipset giving you an additional set of 2 PCI-X 100 and 1 PCI-X 133 slots
Thank you for playing - come again
Re:I don't think that will work

Custom Motherboards?
·
· Score: 2, Informative
Actually - the PCI-Express Chipset for AMD (The NForce) IS just a HyperTransport - Device chip... It will work for either a single, a dual, a quad, or for that matter an 8 way motherboard.
You can have two of them in your dual proc system (or 4 of them for that matter) and get your multi 16x.
Don't look for any manufacturer to produce such a thing, and frankly - doing a custom motherboard is probably out of your reach unless your first name is Bill and you don't mind throwing down a few million for a custom job
So, this guys claim to fame is he worked at Excite@Home and was the CIO of the state of Utah... Well, and maybe having his own website up there at phil.whendley.com.
Seems kind of far from a Nationally recognized expert to me. I'd never heard of him - why do I associate his name with a talk that Vint Cerf gave and apparently this guy gave no value too, other than driving there and listening
So - robotics/electronics is about two things...
1) Embedded programming models
2) Funky I/O devices
So which one do you want to focus on - from your post, I am guessing it is the later. So what you want is a brain dead easy programming model - then build the I/O devices (ie. Sensors, motor controls, all the fun things to manipulate the physical world) to fit into the programming model.
The alternative is to get a canned hardware model (ie. Mindstorm) and then present interesting project in having the hardware manipulate the real world.
Leave it to VERY seasoned profesionals to manipulate both of these environments at the same time, and even then - there are hardware people and there are software people... and they tend not to mix
A connection ???
A modem link to a BBS ? Well, that goes back 25 years now. God the days of Compuserve (remember them, they didn't get the internet and lost out to AOL)
And frankly the whole Capital I thing is stupid, if I wasn't talking about the internet, I would have said, LAN, BBS, or other technology .
Actually 84 - Remember the great switchover of 84... What a day that was. Of course I only got to hear about it as I didn't get on until a couple months later
Just wondering how little work I could get done without a network connection
Think about it

Frankly, I'm suprised you even can get people to work for you, I mean - wow, I haven't worked somewhere without an internet connection on my development machine for almost 15 years now. And it has been north of 20 since I haven't had an internet connection
Frankly, it is much easier to protect your IP, and go after the people that steal it... I mean really what is stopping someone from bringing in a micro hard drive and just taking the whole thing out.
Looking out at the parking lot - there are 2 H2 Hummers, my Prius, a few sports cars, 4-5 SUVs and a bunch of mid-sized cars. I will bet the fuel economy of the parking lot here is somewhere around 24-25 - which actually isn't too bad for the US.
Go look at a lot in Europe, and I will bet the average gas milage is 5-6 MPG higher, add higher gas prices - and I could see average gas milage raising to 35.
That doesn't even get into things like people giving up cars for public transportation, alternatives like biking (my favorite), or moving closer to their office (I've known people that drive 100 miles a day - usually in low milage cars, lets see what happens when it costs 40-50 dollars a day to get to work), or many other alternatives
Keep the government out of my healthcare and retirement...
Yeah - gas prices are way to low... Lets make sure and tax gas consumption more, maybe getting gas up to European levels (oh about 6 bucks a gallon)... Makes me glad I have a Prius instead of one of those gas guzzling H2s - and frankly living 3 miles from work doesn't hurt either... He He He
Don't forget that the 500mA is shared between ALL of the devices connected to the port. So if you plug into an unpowered USB hub sharing with a few other peripherals, the 500mA goes down from there
When will these groups stop giving awards for bad music to artists that sell out so their fans can't even access their music if the artist wants to let them
Also, you may get bugfixes, and other contributions from the community of contractors and users.
Except not even the GPL would require anyone in the community that is using your code inhouse to give you back any code - so you have gained nothing, except maybe giving a competitive edge to your competitors. If your app really is worthless, then sure give it away - but then, why did you waste your time and effort on it.
Corporations use this all the time. Have you watched any large company (Boeing, Intel, etc.) talk about building their next plant. Let the municipal/state bidding start on who can offer the lowest tax rolls. I hope this works out well for the lowly peon as well, let the corps move to low corp tax states, and all their worker bees move to low individual tax states - that way no one pays any taxes and the governments can hold a bake sale to hire the next police officer

Online is a scary place to be isn't it ?
I guess in the grand scheme of things - this whole time should count as negative
