most companies do zero or nearly zero research before ordering a $4K dollar workstation, they just ask what can they get for $4k that will run $CAD_OR_ENGINEERING_APP of choice. Trust me I have ordered probably a million worth of workstations over the last 3 years or so and other than ram amount and disk subsystem size I almost never ask what cpu is in it, I just order whatever HP or Dell is in the pricerange the manager has in mind and is certified on their divisions applications. We did order some oddball systems for one group that tends to order a large number of systems (asic synthesis and routing are major cpu users) just to see what we could do on price/performance but that's only because they tend to order 20+ workstations at a time for their work farms and it made sense to buy like 3-4 alternatives before getting a large order.
What are you on? Intel has in fact depened the pipe to get an architecture that scales to higher speeds, but except in invalid branches and cache stalls this works pretty darn well (it's nothing like wait states), and a lot of the impact from cache stalls can be minimized by having a second set of instructions flying in the hyperthreading unit (assuming it doesn't need data that will be staled out of cache so that it too stalls). The fact is that average case Intel's aproach works pretty well, best case it flies (see media apps), and worst case it can really be slammed, not bad tradeoffs on average. Just because AMD did not choose to go down the same road does not mean that it was an invalid design decision, in fact since most of the applications that actually stress a modern cpu have a similar profile to the media apps it seems to be a pretty good decision overall.
Yes there are bad benchmarks but SPEC's benchmarks are pretty good baseline indicators (there have been some exceptions when people wrote specific optimizations into their compilers for the SPEC suite, but those companies got pretty trashed in the computer press for it)
Depend on the app, pointers aren't the only datatypes that are extended to 64 bits, int types are too. Also because of more numerous registers a simple recompile with no code changes can give a 30-40% performance increases. Look at the results for Unreal 2003, no code changes and they got a pretty nice performance jump =)
Oh I can't believe this didn't get modded up, I guess the joke went right over the head of all the mods with points =) What great subtle humor, though I guess it was a little too subtle for the great unwashed.

Well here is a quote from the TOS for Verizon's data service and I have found that most of the good cellular data plans include similar exclusions (IE those that don't charge for every MB over some rediclulously low amount, wtf would I want fast data rates if I have to pay for everything over 20MB???).
Unlimited Express Network cannot be used with server devices or with host computer applications. Examples of such prohibited uses include, without limitation, web camera posts or broadcasts, continuous jpeg file transfers, automatic data feeds, telemetry applications, automated functions or any other machine-to-machine applications.

Most cell networks have explicit sections in their data provider agreements that forbid applications like security cameras. Trust me they have already thought of how much of a drain a bunch of cameras constantly sending pics would be on their network and made it so they can shut your service off if they find you doing something like this.
Often explained as the velocity need for an object to reach infinite distance from another object.
Not really, in the case of a multibody system you only need to achieve a point where the gravitational pulls of the bodies are balanced so that you aren't moving towards any of them.
Well in my position yes, but I actually saw our IT security folks do basically this (the letter wasn't blackmail material, I would do that just to pound it into their thick skulls =). In addition they hid their badges and tailgated in, then walked off with unsecured laptops. At the end of the week they gave a presentation to the whole building on their finding and boy did things change for a while, of course I think the lesson needs to be repeated once in a while to be truely effective (you know the whole Pavlov thing)
I bet that's a password gatherer and you've just been waiting for slashdot to run a story on something related so you could gather tons of passwords =)
The way I would do it if I was serious about raising awareness would be to go around gathering passwords, make a blackmailable letter and send it to myself from each of the guilty parties. I would then go to them with said letter and say "see what someone can do if you just leave your password around or give it out freely."
One reason this doesn't work is the old "remember X old passwords" thing. If people are comfortable with their current password and are rushed for time most of them would much rather give the local help their password then change it and be forced to remember a new one. If people asked I told them honostly I would not remember it later and that I really had no desire to know it, I already had local root for all machines and domain admin for the local domain so its not like I couldn't get to everything already. The only thing their individual password might have gained me would be the ability to spoof their identity, and if I wasn't trusted after two background checks and a couple years working there then who could they trust?
Actually for once Bush might have got the budget numbers right. The cost so far has been 20 Billion, with about another 20 Billion needed over the next 4 months or so for the remaining military actions and the following police actions. This is not a very large cost and only about 12% of last years military budget. In other words it is far from a budget breaker and will probably be offset by decreased energy costs over the next year or two.
That looks good, with the 1150mAh battery it looks like it might actually make him happy =) Now I just have to find out if it is available in N. America and if so can I get it working on AT&T's network easily.
Is there a bluetooth capable phone that has over 3 hours realworld talktime? My dad uses his phone an insane amount and absolutly goes crazy if his phone's battery dies during the day. I would love to get him a bluetooth phone so I can put to gether a CE based invoicing program and have it fax the invoice through the cellphone.
What they don't implement traverse folder, list contents, read/write attributes and extended attributes, delete subfolders, and delete permissions? These are all NTFS permissions that are part of CIFS from what I remember.
Windows in the datacenter, hahahahaha, maybe for the branch office datacenter to handle logins and dynamic dns but that's about it. Any real corporate datacenter will be mostly unix and Z series (nee S/390) machines with maybe some VMS or other legacy systems.
exactly, it is much, much harder to get an NFS system properly secured then a CIFS system. Since CIFS is now an open standard I don't see much reason not to use it. I just wish there was a better way to map unix permissions and CIFS permissions onto a single filesystem, this is one of the most frustrating thing about admining our netapps.
actually our fileservers are netapps =)
And no we can't force them to keep all their doc's on the fileserver. They are engineers and corp policy is all business critical files must have at least one recent copy on a backed up fileserver. Other than that we have no say and if we bug them about it we get yelled at for not being customer friendly. Of course when the managers have to pay thousands for HDD recovery service they generally get on their employees about running the backup software and trying to keep things on the server, but that lasts for about a quarter until they get their new budget and forget about the cost.
You assume everything is kept on the fileservers, not in most environments. Yes you want to save thing off to the fileservers for distribution and backup but most people work on their files on their local pc's. This is the situation at almost every shop I have been to.
I believe the two major compressed X packages are DXPC and LBX of which I have only used DXCP (it made X barable over a 28.8 dialup but latency was an issue)
Why would this use anymore network banwidth???? This is an X Server, as in the display path. It will take the same X networked primitives and render them using local 3D accelerated hardware, it doesn't change the networking part of the X protocol at all. As for getting term services like network compression for X why don't you try one of the compressed X extensions, they are usable over dialup (if a bit slow due to higher latency) so they should be super over even 10Mb ethernet. Then again I was on a campus with thousands of people doing remote X sessions over 100Mb switched ethernet almost 7 years ago so if 10 diskless terminals is slowing down your network I would look elsewhere for the culprit.

Yep, ipblue was the (unofficially) recomended solution inside Cisco as Cisco's own softphone kind of sucks =)
I assume they use LEAP which authenticates to a number of different RADIUS servers including of course Cisco's.
