What operating system should i install on a VERY old computer?

Q. The computer again is extremely old, ie 5-6 years (integrated graphics, 1 gig ram, pentium processor, etc). Now i want to find an OS that is both simple to use and one that will run efficiently, especially for viewing photos and movies (obviously this is bottle-necked by hardware, but there should be differences in memory and cpu usage from OS to OS),

So what do you suggest? the new chrome OS, win XP, ubuntu?

A. Old machines run best on what they were designed for, But time marches on and computer os support runs out of steam. If your machine was designed for XP os then use it, upgrade as much of the hardware as economical and go from there. You may find it would be best to purchase a new machine rather then try to upgrade on your own. If that is not an option and you are determined then you should start with the memory, then the video card. If your machine is at least a P4 running at close to 2.0GHz then you will have a chance depending on your technical ability. If not then you should shop the internet for a used system that is within the price range of what you are going to spend on upgrading your machine. To answer your question Google Chrome OS is only to be used for the modern netbooks (condensed and stripped down laptop computers), Win XP was most likely the OS that was installed at the factory on your machine, and Linux Ubuntu is free and open source software.... XP is my choice

How to find my Linux System Information?
Q. I know how to find it on Windows. But how do I find my system information on Linux Operating system. Thanks.

A. Open the command prompt, it might be known as Terminal. The following commands will allow you to find your system information.

System Information
archPrint machine architecture.
df Shows disk free space.
duShows disk usage.
freeDisplay used and free memory on the system.
ipcrmProvide information on ipc facilities.
ipcsSame as ipcrm.
lsdevDisplay information about installed hardware via files in the /proc directory.
lsofList open files.
lspciList PCI devices .
pnpdumpLists ISA plug and play devices resource information.
procinfoDisplay system status gathered from proc.
pstreeDisplay a tree of processes.
runlevelFind the current and previous system runlevel.
straceTrace ssytem calls and signals for a binary program.
sttyChange and print terminal line settings.
tloadPrints a graphic representation of the system load average.
ttyPrint the filename of the terminal connected to standard input.
unamePrint system information, Prints Linux.
vmstatReport virtual memory statistics.
xcpustateDisplays CPU states (idle, nice, system, kernel) statistics. Runs in X?

Knowing what distribution you use would be helpful. If you need more help I'd recommend looking at the website of the distribution you use.

Should install Linux and get rid of Windows Vista?
Q. Ok So I have a laptop and have Installed Windows Home Premium; I am wondering what is Linux? I do not know yet but I am wondering if I should install Linux and un-install Windows Vista? Please, someone Help, Should I? Which one is Better?

A. Linux Ubuntu +++++++++++

I am so glad to get rid of the intrusiveness of Windows Vista. Linux belongs to the user. not the other way around. No agreements to sign, no automatic updates that pull the rug out from under your feet, so you are forced to buy new computers. No need for expensive protection systems. It is like having a brand new computer. After having most of my memory wasted with access systems, and then finding out that they not only did not work, but just took up space, and then being denied access to get rid of them.......

You can load Ubuntu through your Windows system and try it out for free, as a separate operating system on the same computer. If you are not impressed. Just delete it. Try doing that with Window. Windows is in charge of your usage with it's system. You are in charge of your system with Ubuntu, Lenox.

If you get the disc, which is absolutely free, including postage, you can erase windows and all of it's quirks from your computer, and have ten times as much memory available with the same number of programs.

How do you show the processes that are running in linux under a command line?

Q. And, how do you show how much memory and cpu each is using?

A. Check out the manpage for ps. The most common syntax is "ps auxww" which will show PID, CPU usage, Memory usage, process name, etc for each process that is running on your system. "top" shows real time information and ranks processes by their CPU/RAM usage.

What slows down computers besides memory usage?
Q. I just deleted a whole lot from my laptop, and I ran a 'defragmentation' on the hard-drive, but it's still going really slow. Any ideas?
More detail: It's slow to open programs or new windows. There's a delay between when I click an icon and when the window opens.

A. Are you familiar with the Task manager? (Ctrl+Alt+Delete) The task manager will show you which processes are using you processor power and how much virtual memory.

What version of Windozes? Have you tried using a registry cleaner? Do you have a reliable anti-virus?

When I used to use Windozes, I had to wipe it about every 6 months and start over. It just seemed to get unstable after prolonged use. I now use Ubuntu Linux.

How to measure the performance of an Linux C application?

Q. I have written a C code, which uses fread, fwrite,. I want to measure the performance like No_Of_Blocks read and written by the application. disk usage, memory usage etc. Is there any tool to measure the performance of an application in linux?

A. lets see:
You can measure CPU performance using /proc/cpu. You can measure ethernet performance by using /sbin/ifconfig <eth_port>. You can use df to track data written to a filesystem/mountpoint. Take a before and after snapshot using the tool of choice and determine the metric you wish to measure.

What is the corresponding free command on an AIX machine?
Q. I'm programming on a machine running IBM AIX version 6.1. I'm trying to profile the memory usage so I'm looking for a command similar to the free command on Linux distributions. Help

A. svmon and vmstat

What Norton Antivirus product should I buy for protecting 6 server machines running windows 2003?
Q. I'd rather run Linux but.. some government people, probably don't know much about computers at all, are forcing us to use Windows.

They want Norton protecting all of them, despite only two of the machines being externally visible.

A. There is a corporate version of Norton Antivirus that has a much smaller memory/cpu usage footprint than the normal retail versions. Its just Symantec Antivirus 11.0. However, they now call it Symantec Endpoint Protection. I'd go with that to keep it simple.

Does vista use different amounts of RAM depending on how much there is?
Q. My vista laptop uses just under 50% when doing nothing and has 3gigs of RAM but my desktop uses also just under 50% when doing nothing and has 2 gigs of RAM. Does vista use the more RAM the more there is? Or is there another reson for the differences in RAM usage?

A. Yes. And this is true of all NT-derived versions of Windows (NT, 2000, XP, 2003, Vista), although Vista is a bit more proactive about prefetching (and this is why people think it's a "memory hog").

And all other modern virtual memory OSs too (MacOS, Linux, BSD, etc.

However the amount of "RAM used" is misleading. The "RAM used" does not mean there is a permanent commitment to the present uses. If something else needs the RAM, things that are "using" it now can be trimmed back and give it up very quickly.

In the case of the file cache, the RAM used by prefetched file data can be released for other use just as quickly as if the prefetching had not happened at all.

So a lot more RAM is really available to, say, a new app, or to meet a sudden need by an already-running app, than you might think.

edit - Windows Sidebar? Nah. At the moment, in my 8 GB (Vista x64) machine here, Sidebar is using all of 30 MB RAM. Granted I have no gadgets except the default MSN news thing. This is the "Working set (memory)" column in Task Manager - used to be called "Mem usage".

The biggest memory user in Vista that you can easily do without is dwm.exe, the "desktop window manager". You get rid of this by disabling Aero. This loses you the transparency at the edges of windows, the live windows displays in "cool task switching" (alt-tab) and in the taskbar, etc. Even so, though, dwm.exe is like nearly everything else - it's only allowed to bloat when there's plenty of free RAM to bloat into. If something else starts up and needs some RAM, dwm.exe and everything else get trimmed back to make room.

What Linux operating system can you use to install Windows-based software right away with no software used?

Q. For example, Ubuntu needs a program called Wine to install Windows-based software. So is there another Linux OS that can install them right away? And if so, whats the lowest Linux OS memory usage?

A. Linux is Linux, Windows is Windows, the code base are different so theres no such thing, if there were, one would think no one would buy Windows anymore wont you ?

Is there a free app to monitor your system activities on Windows 7?
Q. I would like to monitor my network activities, memory usage, and other processes.
Something like the activity monitor that Mac OS X and Linux have? Please and thank you :)

A. I'm not sure if this is what you mean but there is a task manager.
Press Ctrl>Alt>Delete then select start task manager
:)

What operating system should i install on a VERY old computer?
Q. The computer again is extremely old, ie 5-6 years (integrated graphics, 1 gig ram, pentium processor, etc). Now i want to find an OS that is both simple to use and one that will run efficiently, especially for viewing photos and movies (obviously this is bottle-necked by hardware, but there should be differences in memory and cpu usage from OS to OS),

So what do you suggest? the new chrome OS, win XP, ubuntu?

A. Old machines run best on what they were designed for, But time marches on and computer os support runs out of steam. If your machine was designed for XP os then use it, upgrade as much of the hardware as economical and go from there. You may find it would be best to purchase a new machine rather then try to upgrade on your own. If that is not an option and you are determined then you should start with the memory, then the video card. If your machine is at least a P4 running at close to 2.0GHz then you will have a chance depending on your technical ability. If not then you should shop the internet for a used system that is within the price range of what you are going to spend on upgrading your machine. To answer your question Google Chrome OS is only to be used for the modern netbooks (condensed and stripped down laptop computers), Win XP was most likely the OS that was installed at the factory on your machine, and Linux Ubuntu is free and open source software....

If your machine was designed for XP os then use it, upgrade as much of the hardware as economical and go from there. You may find it would be best to purchase a new machine rather then try to upgrade on your own. If that is not an option and you are determined then you should start with the memory, then the video card. If your machine is at least a P4 running at close to 2.0GHz then you will have a chance depending on your technical ability. If not then you should shop the internet for a used system that is within the price range of what you are going to spend on upgrading your machine. To answer your question Google Chrome OS is only to be used for the modern netbooks (condensed and stripped down laptop computers), Win XP was most likely the OS that was installed at the factory on your machine, and Linux Ubuntu is free and open source software.... XP is my choice

What is the corresponding free command on an AIX machine?

Q. I'm programming on a machine running IBM AIX version 6.1. I'm trying to profile the memory usage so I'm looking for a command similar to the free command on Linux distributions. Help

A. svmon and vmstat

How do you show the processes that are running in linux under a command line?
Q. And, how do you show how much memory and cpu each is using?

A. Check out the manpage for ps. The most common syntax is "ps auxww" which will show PID, CPU usage, Memory usage, process name, etc for each process that is running on your system. "top" shows real time information and ranks processes by their CPU/RAM usage.

What slows down computers besides memory usage?
Q. I just deleted a whole lot from my laptop, and I ran a 'defragmentation' on the hard-drive, but it's still going really slow. Any ideas?
More detail: It's slow to open programs or new windows. There's a delay between when I click an icon and when the window opens.

A. Are you familiar with the Task manager? (Ctrl+Alt+Delete) The task manager will show you which processes are using you processor power and how much virtual memory.

What version of Windozes? Have you tried using a registry cleaner? Do you have a reliable anti-virus?

When I used to use Windozes, I had to wipe it about every 6 months and start over. It just seemed to get unstable after prolonged use. I now use Ubuntu Linux.

How to measure the performance of an Linux C application?

Q. I have written a C code, which uses fread, fwrite,. I want to measure the performance like No_Of_Blocks read and written by the application. disk usage, memory usage etc. Is there any tool to measure the performance of an application in linux?

A. lets see:
You can measure CPU performance using /proc/cpu. You can measure ethernet performance by using /sbin/ifconfig <eth_port>. You can use df to track data written to a filesystem/mountpoint. Take a before and after snapshot using the tool of choice and determine the metric you wish to measure.

How to find my Linux System Information?

Q. I know how to find it on Windows. But how do I find my system information on Linux Operating system. Thanks.

A. Open the command prompt, it might be known as Terminal. The following commands will allow you to find your system information.

System Information
archPrint machine architecture.
df Shows disk free space.
duShows disk usage.
freeDisplay used and free memory on the system.
ipcrmProvide information on ipc facilities.
ipcsSame as ipcrm.
lsdevDisplay information about installed hardware via files in the /proc directory.
lsofList open files.
lspciList PCI devices .
pnpdumpLists ISA plug and play devices resource information.
procinfoDisplay system status gathered from proc.
pstreeDisplay a tree of processes.
runlevelFind the current and previous system runlevel.
straceTrace ssytem calls and signals for a binary program.
sttyChange and print terminal line settings.
tloadPrints a graphic representation of the system load average.
ttyPrint the filename of the terminal connected to standard input.
unamePrint system information, Prints Linux.
vmstatReport virtual memory statistics.
xcpustateDisplays CPU states (idle, nice, system, kernel) statistics. Runs in X?

Knowing what distribution you use would be helpful. If you need more help I'd recommend looking at the website of the distribution you use.

Should install Linux and get rid of Windows Vista?
Q. Ok So I have a laptop and have Installed Windows Home Premium; I am wondering what is Linux? I do not know yet but I am wondering if I should install Linux and un-install Windows Vista? Please, someone Help, Should I? Which one is Better?

A. Linux Ubuntu +++++++++++

I am so glad to get rid of the intrusiveness of Windows Vista. Linux belongs to the user. not the other way around. No agreements to sign, no automatic updates that pull the rug out from under your feet, so you are forced to buy new computers. No need for expensive protection systems. It is like having a brand new computer. After having most of my memory wasted with access systems, and then finding out that they not only did not work, but just took up space, and then being denied access to get rid of them.......

You can load Ubuntu through your Windows system and try it out for free, as a separate operating system on the same computer. If you are not impressed. Just delete it. Try doing that with Window. Windows is in charge of your usage with it's system. You are in charge of your system with Ubuntu, Lenox.

If you get the disc, which is absolutely free, including postage, you can erase windows and all of it's quirks from your computer, and have ten times as much memory available with the same number of programs.

What Norton Antivirus product should I buy for protecting 6 server machines running windows 2003?
Q. I'd rather run Linux but.. some government people, probably don't know much about computers at all, are forcing us to use Windows.

They want Norton protecting all of them, despite only two of the machines being externally visible.

A. There is a corporate version of Norton Antivirus that has a much smaller memory/cpu usage footprint than the normal retail versions. Its just Symantec Antivirus 11.0. However, they now call it Symantec Endpoint Protection. I'd go with that to keep it simple.

What operating system should i install on a VERY old computer?
Q. The computer again is extremely old, ie 5-6 years (integrated graphics, 1 gig ram, pentium processor, etc). Now i want to find an OS that is both simple to use and one that will run efficiently, especially for viewing photos and movies (obviously this is bottle-necked by hardware, but there should be differences in memory and cpu usage from OS to OS),

So what do you suggest? the new chrome OS, win XP, ubuntu?

A. Old machines run best on what they were designed for, But time marches on and computer os support runs out of steam.
