  1. Can you please be more precise while asking this? What are you talking about?Looks like a question your teacher asks you in order to se if you were sleeping during last course, isn't it?More precisely, the DBMS is the database system, or what were you talking about?


  2. I will try out the Opera portable sometime this week and see if the issue exists on it... it's most probably just an issue with Opera on Windows XP...

    If the issue is inside your PC, the portable version will experience the same issue.The main advantage in this situation is that the portable version will remain the same one when you move it to another machine, so you can test if the problem is inside the machine or remote.

  3. agree... tutorials are some of the reasons why i'm using youtube

    This is a funny and paradoxal situation. A lot of supposed serious websites are actually used for entertainment. And Youtube, which is known as an entertainment website, is also used by a lot of people for storing very technical tutorials.
    That's an example of the free world evolution, you think that something will happen a given way, and free users push it in another direction. Nice example of chaos theory example.

  4. We need to know how these F1-12 keys are handled on your computer.Probably a daemon task is running on your computer, trapping these keystokes.If this is the case, simply kill the program and restart it when you stop playing on the computer.And if it's a service, just stop the service.If you have enough cpu and memory, another way could be playing games on a virtual machine hosted on the same computer. So, you don't need to change your physical computer settings. Should work, when you will be on the virtual system the F1-F12 keys should be passed to the virtual OS, and not to the physical system.


  5. exactly... and that's why i said there's a lag problem... yordan seems to think otherwise - that's its a VM issue

    We should not mix the problem.When my Windows host has 2 gigs free, this means that I can give 2 gigs to a virtual machine. As long as there is a lot of memory free, we are testing the cpu performance.
    The disks in the PC can be accessed by a single process which exhaust the whole disk bandwidth. This means that you can comfortable work on your native host, or on your VM machine, but not simultaneously on both - except if you have fiberchannel adapters connected to a decent SAN.
    So, do not mix cpu-access problems and lack of memory problem.
    My friend has a 8-core laptop with 64 gigs memory, on a virtual machine he opens a big Excel file ten times faster than I do on my native XP laptop. Of course this will not make me switch to a bigger laptop, I simply know that if I had far more money, I could work far more efficiently. Simply waiting one hour costs less than finding $1000.00 in order to buy a bigger hardware!

  6. And the probloem with

    that I did a fresh install, the problem still exists.

    "Fresh install" is different from "first install". After the first install on a Crosoft DoDows machine, a lot of things are written on the registry and in the system settings places.a Of course, this is also the case on Linux machines, simply the storage places are different.
    So, what you think being a "fresh" install is replacing some file by other ones, but system settings don't change.
    That's why, each time it's possible, I use a portable version of FireFox (or chrome), in case of trouble I remove my folder and uncompress the portable software again so that I'm back to the initial settings. ;)

  7. so you're saying that running a Guest OS will be no different in performance (including lags) then actually installing it on the drive itself?I think the opposite

    I think that there should be at least a small effect.
    Vmware people claim that there is no difference in perfomance between a virtual machine using a given hardware, and the same operating system using the same hardware.
    Some colleagues claim the same thing. Else, the whole cloud thing could not work, if too much power would be lost.
    And, of course, if the thing is made correctly, this could be true.
    Crosoft Windows uses a driver of the native machine in order to access the disk.
    The OS inside the virtual machine sends requests to the vmware daemons, which pass the request to the native system drivers. So, at the end, the same drivers are used the same way to access the same devices.
    There could be a bug making a need of retry on the SCSI or IDE channel, which would make a loss of performance, but the bug will be solved in the next vmware release.
    There could be a very simple test.
    Create a 10 gig partition on a native hard drive, and make a disk benchmark test on it.
    Then give that partition to a virtual machine and perform the same test.
    These two tests should give the same result.
    Of course, in order to be valid, the test should not be performed on a partition, but on a full disk, using the same full disk for the native system and for the virtual machine system.
    If you see a difference, you are rich : you sell your test to the VM designers and help them solving the problem, and you will receive a lot of of money for that very good job. :wacko:

    -- EDIT --
    forget this, I will contact them and I will become very rich

  8. hehe quite true... i presume it would run alot better if it is installed on hard-drive

    If it's a VM, it's on the hard drive! It's supposed to be as fast as the hard drive of your physical machine. The only difference could be if the vm hard drive does not correctly manage the Windows8 disks.
    If this is really the case, it will be fixed in the next vmware release, because Windows 8 will the one of the major releases for the professional systems clouded by vmware.

  9. for me three buttons is enough...
    i had a mouse that came with a laptop i use to own few years back (a ASUS G1S or GS1)... it had 5 extra buttons

    In my opinion, a standard guy has five fingers, so he can efficiently use no more than five buttons.
    Moreover, if he wants to be able to move the mouse, he needs two fingers dedicated to mouse moving, so only three fingers are available for buttons.
    Of course, this statement does not apply to fps shooting games nor to space-rockets adventure games, where you keep the mouse with two hands for more precision, and then you have ten fingers available, then you can devote each finger to each of the weapons you acquired. You needed so many time for earning the money in order to acquire that weapon, you have plenty of time for deciding which finger will use this new weapon and which movement will better optimize your placement for using it.
    So, my definite opinion is :
    For stand one-hand mouse users, a two or three button mouse is enough.
    For two-hands mouse users, up to ten buttons can be managed. But you will lose time when switching from mouse-handling to keyboard-typing. So, if ten buttons is not enough for your game, switching from mouse to keyboard will be really time-consuming and you will suffer a tremendous lack of performance.

  10. are you saying it can hold 60 copies of the web? i'm sure the web is way more than 120million Gigabytes by now

    OK, Bob said "the biggest backup". And, of course, the web is not a single website, each system needs to have a backup, and we can imagine that the biggest single backup somewhere is 20 terabytes, which of course needs to be multiplied by the number of single copies (monday backup, wednesday backup, week-end backup, monthly backup at least).

  11. That's a modern feature.Some tens of years ago, it was normal to wait until three other persons are free for playing cards.Today, if I want to play, I want to do it right now. It's possible with online games, without waiting.It's a modern times feature : we want everything immediately.I still think we can mix both : playing online as soon as I want, and playing around a table with my friends as soon as they are available, maybe next month.


  12. i would like a run command for getting to a Connections Properties... especially if its only one Network Connection available

    You want to know or to change the properties ?
    To know the properties, just type
    ipconfig /all
    Of course, it's "ifconfig -a" if you are on a Unix or a Linux system! :D
    And, to change the properties on a windows system, what about righ-click or left-click on the small network icon? Or right click on the "network" icon on your desktop? That's what is done by most of the sytem administrators which happen to be as lazy as I am! :wub:
