Great point about token ring. Was heavly used in these types of situations as well. Don't know about LAX but a lot of the airports have upgraded since then. Anybody get to use Switched 100Mb token ring?? To bad that didn't make it. Could have been cool. The advantages of both switching speed and the preformence under load that token ring has.
chimps make flat networks.. with hubs.. what are switches and routers? I agree run into this problem several times in my carrer but for real. Bad network design. But hey Ive also worked in wireling closests in airports most of which these days are community run by the airport authority and leased by the airlines or other tennets of the airports. Used to work for an airline. NOT suprised one bit.
I agree about AVG why wasnt it tested. I also use FSecure with some clients and have been very happy with it. Would have been nice to see it in the running as well. Anyone have any experiance with FSecure?
Talk about not seeing the big picture! Anyone that thinks.. Apple of all people should buy AMD!! Apple doesn't know anything about Enterprise Servers or real supportable hardware. That be great, sorry sir but your AMD power computer is broken. We are not going to give you any information on how to fix it but you can bring it our store and well do it fo $100. $50,000 to be a VAR with Apple. Apple is the worst.. worst than Microsoft. There I said it! Its true. Try supporting Linux, Windows and Apple. Which on doesn't play nice with the others? This would almost make me want to change professions.
Well that by it's self is enough. What? Chock this one up for, sorry folks but people are still.... stupid and have no idea what "good" is. We even talked about Bose a few weeks ago. COME ON PEOPLE! Think for yourselves!!!
"If you want to use Linux as your host OS, you'll definitely have to go with VMware."
What is he talking about? From this one sentence it is obvious that this person should have never written this article. VMWare ESX server is not Linux. VMWare ESX VMWare's own creation kernel and all. Not to say they could have barrowed parts from who knows where but it is not a 2.4.x Linux kernel or anything of that nature.
Now to the inexperienced user, installing and administration VMWare ESX you might get the impression that VMWare ESX is linux since the "service console" is based off of Red Hat. But this is not the hart of ESX, merely to local and remote configuration interface into ESX.
The fact that you can patent such broad ideas as people are allowed to, by itself COMPLETELY undermines the entire patent system. To make it worse all these patents are issues for the broad ideas (like "ecommerce payment") something that can be done a thousand different ways, and the kicker is half the time the people holding the patents havnt even made there idea work!!
In response to everyone's comments on Bill's office as seen in the photo(for which I too noticed right off the bat his cheap table etc. I have a nice desk in my cube at the Fed!) Anyway, anyone think that maybe this isn't Bill's office at all and was just set for them to take a photo real quick??? "Ok, we need three flat panels, a tablet pc, oh oh and he said he keeps is Outlook open on the left screen...."
All I have to ask.. is.. honestly... what did Apple ever do to you? Tell me, what is really going on? What in your life is really bothering you? Take your time....
This is so true, the name brand issue. First, I would buy Sony WAY before Bose... The audio market is probably one of the worse for brands being thought of in the main stream, almost in exact opposite order of reality. Bose, for the money is some of the WORST speakers you could buy! Finally some said it! Don't remeber what those crapy home speakers cost they sell but for the same price pick up some self powered "studio monitors" at your local music equipment store and youll be vary happy that you did!
Just last night this topic was brought up in my mind. I went to see a film on an IMAX screen. For two people it was $22 just for tickets. That was alright at that point, however by the end of the night it was a waste. About half way through the movie my Girlfriend and I decided we would be happier just leaving. The movie wasn't that good, seriously you can't be as comfertible at a theater as you can in your living room, on your couch, with a friend or whatever. Not only that you don't have people sitting behind you and you don't have to worry about bother others either. For me DVD is the thing. The "better experiance" you get at a theater (sound, screen) is not enough to over through personal space comfert, etc. That I have at home. Give me a big screen and A DVD player and a couch. Thank you. Maybe Ill buy a projector too, let's see? If you saw one movie a week you could buy a projector in a year.
This is simple, I already have these speeds and faster, during the wee hours of the morning my actual file download speeds in applications have been over 100KBy Sec. Slowest was 30KB a sec at peak times. This is for a lowly $20 a month for my Power Vision servers through my Sprint Samsung Phone. Love it. I could actually only be paying an extra $10 a month if I wanted. I opted for the bigger plan for for free streaming crap on my headset, not part of my unlimited net feed!
Garmin International is hiring Elec Engineers. There right down the street, come to the home of Sprint, Hallmark, Applebee's, and the best damn BBQ in the world!
Indeed. This is not uncommon at all. I am aware of a huge Linux cluster installed at a research center at a major univeristy, NASA funded at times, spent about $1 Mil on hardware. In the end, one professor used it, and not all that often. It was sitting ideal with maybe 2% CPU unitilization for months and months while others where begging for time. The one professor, again, like a 3 year old with candy. What a terrible waste of resourses. Great motivator huh!
An AT&T 8086. Did have a 1200bps modem. Was super cool when we dialed two of these bad boys together and played some Jet Figher game against each other from across town! Yeah!
And I thought they where talking about spitting wars between flamers.
It would be a contest to see who could write something that could be taken two completely different ways. Then no conclusion.
Once again it has nothing to do with what I can or want to do. This should not be nessisary. Windows works out of the box in a VM. Also I'm using SuSE Enterprise Linux provided to my by my manager, shouldn't this be set to 100 if your saying servers are supposed to? Regardless it shouldn't need a kernel recompile. Tierd of that being the fix, just recompile the kernel! Starting to feel how Linux is slacking.
Getting it done an setup in a busy Enterprise company takes time that shouldn't be needed. They need to fix this in the virtualazation software. SuSE should work in a VM out of the box.
Anyone failure with virtualization and Linux guests will know about Time Sync issues that are around. I have experienced this with SuSE Enterprise Linux guest running on VMWare ESX Server. My question is does anyone know if this virtualization system has taken care of this issue.
Basicly put, Linux guests loose or gain time, up to hours a day. Major issue in the enterprise.
The issue is described below, this is taken from the VMWare knowledge base.
Linux guest operating systems keep time by counting timer interrupts. Unpatched 2.4 and earlier kernels program the virtual system timer to request clock interrupts at 100Hz (100 interrupts per second). 2.6 kernels, on the other hand, request interrupts at 1000Hz -- ten times as often. Some 2.4 kernels modified by distribution vendors to contain 2.6 features also request 1000Hz interrupts, or in some cases, interrupts at other rates, such as 512Hz.
Furthermore, an SMP-capable Linux kernel requests additional timer interrupts from the virtual local APIC timer. An SMP-capable kernel running on a one-CPU system generates twice as many total timer interrupts as the corresponding UP kernel, while such a kernel running on a two-CPU system requests three times as many. In general, an SMP-capable kernel running on CPUs requests times as many interrupts per second as a UP kernel. For example, an unmodified 2.6 Linux kernel running on a two-CPU virtual machine requests a total of 3000 clock interrupts per second.
When a guest asks for more than 1000 clock interrupts per second, it can be difficult for the virtual machine to keep up, especially if other applications are running on the host at the same time. This can cause the clock in the guest operating system to fall so far behind real time that it is unable to catch up. The overhead of delivering so many virtual clock interrupts can also hurt guest performance and increase host CPU consumption.
It can also be difficult for the guest operating system to field 1000 clock interrupts per second. Even on real hardware, clock interrupts are sometimes lost because the operating system is busy for more than 1 millsecond and another clock interrupt comes in before the previous one was handled. Linux 2.6 contains code to detect such "lost ticks" and correct for them. Unfortunately, this code can trigger the correction spuriously in some cases, resulting in the Linux clock running more quickly than real time. This problem happens more often in a virtual machine than on real hardware, and can cause noticeable time gains. In some cases, the guest clock has been observed to run more than 10% more quickly than real time.

How is that off topic. I was agreeing with this guys statement about a major communications issue in socitiy! WTF?
An AT&T 8086. Did have a 1200bps modem. Was super cool when we dialed two of these bad boys together and played some Jet Figher game against each other from across town! Yeah!
What a great button that was.. HAHAHA.. HAHAHAHAHAHA. Sorry. Just had forgot about that button. and Red Barron. HAh
And I thought they where talking about spitting wars between flamers. It would be a contest to see who could write something that could be taken two completely different ways. Then no conclusion.
For Sure! Yes Yes! Bravo!! *clapping*****
*clap* *clap*
Dad and the Girl are the worst! Come on people!! A little...... effort... pppp...lll..ease?
