Linux is only free if your time has no value.

Funny, relatively few people have problems like these in Linux compared
to Windows. But we all know about the problems Windows has so nobody
bothers mention them any more, while people like you think it's fun to
point the finger at Linux and rave about how bad it is, because of what
happens in a much smaller minority of cases than Windows. )

Would you listen to Micoshaft sponsored fraudsters pounding
their asstroturfing sock puppets that claim something as big
as Linux has no value just because Linux is a direct threat to their
business?


Certainly NOT!

You would go try some free Linux out first.

If Linux is so bad, then how come something like GParted liveCD
can boot a dead PC and repair a hosed hard disk on a WINDUMMY PC?

And how come Sabayon Linux just boots from CD and has a 3D desktop
with 3D games like Nexuiz?

Also the freeze experience of real life Micoshaft WINDUMMY PCs is that
they freeze more often in every office, every day, every minute of every
day.


Switching to Linux helps prevent freezing PCs in the office (TM).

[Ignoramus2031]

I am administering linux installed on approximately 20 machines (home
and work). Out of them about 16 are Ubuntu. One experiences periodic
freezes (once a week), and that one runs Ubuntu Hardy. I have
approximately 7 or so more Ubuntu Hardy machines (desktops and
laptops) and they do not freeze, in the last 2 months or so at least.

Everything running Gutsy is totally rock solid. However, I feel that
installing Hardy on anything where big money is at stake, is premature
at this point.

I try to make sure that these Gutsy machines are upgradeable. I have a
feeling that Hardy is improving and in several months I will start
deploying it to some production servers.

Somewhat contrary to this, I installed Hardy on my replacement
personal webserver a while ago and it seems to be in good shape, I
will take it to the data center soon.

Well I think it interesting that when Vista goes belly up the fanboys
blame the hardware, the drivers, the OEMs or whatever but when Linux
machines have a problem it's "Linux sucks".

Lets be fair here, I have had several identical machines and one froze
randomly no matter what OS it was running.

Most people live with Windows the way some people live with arthritis.

Could be. Just make sure you actually diagnose the problem.

All too many problem-threads found on the internet consist of various
blind men making stabs at guessing the problem, and offering
superstitious advice such as "switch distros" or "reinstall Windows".

Both operating systems have many diagnostic tools. Everyone who cares
about system maintenance should try to learn to use them.

Just keep remembering to give your Windows machine its medication (aka.
anti-virus and firewall updates) and everything will be fine... ish.

Yep ... and yet, for many years, "reboot" was the help desk's helpful answer
to almost all windows problems.
Thankfully, this is no longer true (or as necessary ) with XP. No data on
Vista, other than multiple lock ups on a lap top while trying to play DVDs.

 

[Igoramus6286]

Here's another one. Today a Gutsy server locked up.

I had this happen a while ago on another server where the disk was
bad, and there were bad sectors in the swap file. The data in bad
sectors confused the kernel (no surprise) and it started doing
oom-killer. Replacing the hard drive cured the problem.

So I want to look at HP Proliant SmartArray disks, but unfortunately,
they are behind hardware SCSI. So smartmontools does not support them,
per Bruce Allen.

So what do I do? How can I diagnoze these disks?

Yeah, I had audacious (audio player) crash on me. Segfault.

And how do I "strace" a system lockup?

Alternatively, has anyone tried running a kernel watchdog?
