MC Fruit Stripe posted:I tried it with Gentoo a while back but it poo poo out because it needed exact and precise access to the system, but how about Linux in VMware? Is there anything keeping me from slapping Ubuntu, Mandriva, Debian etc on a virtual machine? Is it going to work as intended, or is it going to have too many bugs? Linux works great with vmware as the host and/or vm. I'm not sure what problems you had before, but Linux is solidly the most stable OS for running on top of or underneath a virtualization system.

I have three different distributions installed currently, and it works like a charm. The only thing that initially bugged me was that the integrated VMware desktop lags quite a bit. Installing tightvncserver on the linux machine and accessing it by TightVNC instead of the VMware interface helped a lot here - same is for Putty for easy, SSH encrypted shell access

Running it in a VM sounds really good though, I can throw a few distros on there and really mess around. I can't believe I never thought of that before. Every other time I've tried Linux it was on my laptop which I hardly ever use and it's all inconvenient. Now I can mess around with it on my main box. Whee!, and such. I'm thinking Gentoo (always a special place in my heart), Ubuntu and... hmm, maybe one or two more.

MC Fruit Stripe posted:I think the problem was that Gentoo (and keep in mind this was back in the day of stage 1 installs) required I believe two reboots during the install, including one with the OS not fully installed yet. VM threw an absolute fit about that one. I'm confused about what the problem you had was. Installing any linux ontop of vmware should be the same proccess as installing it onto a regular old box... With only exception, that I can think of, being that instead of inserting/removind CD/DVD media you are going to be checking unchecking a box to mount/unmount an iso on the host system's FS. Although I guess oyu can use actual physical media too if you wanted...

MC Fruit Stripe posted:Should. Isn't. Stage 3 worked fine, but stage 1 got nervous on me because it has to reboot and compile the kernel and all that. I couldn't get past that point. I'm still confused about this. Rebooting, compiling, all the rest of the gentoo-isms don't do anything that would be broken inside a VM.. did you perhaps have the wrong target arch selected or something?

Yeah, I wish they were though. There's something so romantic about the whole thing. I know a lot of it was just the placebo effect, but everyone really believed that their gentoo install was so amazingly fast. I'm sure the real gains were microscopic (hence eliminating stage 1 entirely), but drat what a cool idea.

I'm having some trouble debugging a C++ program in GDB:code:This started happening suddenly the other day, but I don't know what I might have changed. The program compiles and runs correctly with the functionality I've added, so the object files must be working correctly. I'm using 'gcc -g', I've recompiled the program and all its needed libraries, etc., and it doesn't help. What's going on?

I was just curious if it's just me or are Linux developers much more expensive? I'm trying to get a Linux project started and it's simply an application set that actually utilizes existing open source Linux projects. I tried the exact same project for Windows and got quotes around $450; the Linux version had quotes of $6500+ for the EXACT same thing.

Where are you getting the quotes and what is the nature of the project? Most programmers on any system won't even start a development project for $450 -- this is a price of something like a php script for a web site.

A guy from my local LUG was recently complaining about this same issue on our mailing list. Good Linux developers seem to be few, and given that if you're a Linux developer you're a hot commodity to the right customer you can tend to overcharge.

I can not for the life of me get my new monitor to display its native resolution in Ubuntu. I have edited the xorg.conf file to add the native res, and it always comes back at 1280x1024 at 75hz. The native resolution is 1400x1050 at I assume 60hz. The manual doesn't state what the refresh rate should be. Manually editing the "VertRefresh" line to say "50-60" doesn't do anything... X restarts at 1280x1024 at 75hz. I went through Xwindows config program, as well as manually changing the xorg.conf. Here's what I have in my xorg.conf: code:

teapot posted:It is looking for file in the directory where the compiler took it from. Unfortunately, I think the problem is deeper. That's the only TimeSeriesDisplay.h around, and GDB knows about it - maybe. It CAN set breakpoints in that header file, and in the other files the program is compiled with - but it acts as if those are older versions of the files, somehow? Let me give an example of how it's behaving: Suppose I have a function threeFifty() at line 350 of Header.h. I start up GDB, and set a breakpoint at Header.h:350, and it works fine. Now, I add some code near the beginning of Header.h, so that threeFifty() happens to be bumped down to line 400 of the file, and I recompile. Running it indicates that the new code is operational. But now I load it up in GDB, and again type "break Header.h:350", expecting that the breakpoint will be at a different place - but 'info breakpoints' indicates the breakpoint is at threeFifty() still. What the hell? And when I make the longer than the old version, GDB doesn't recognize the new lines - it won't let me set breakpoints beyond the EOF of the old version. In these cases, the "old version" is apparently the same as the CVS version. Maybe it has something to do with that, but I'm not sure. I can't imagine that GDB would be looking files up elsewhere, though I'm sure I'm overlooking something dumb here.

I'm running Ubuntu (Feisty) and I can't figure out how to kill the "init" process. I initially tried "sudo kill 1", but that didn't work. Then I read in the kill man pages that it sends the signal SIGTERM by default and that processes could catch it. That's no good, maybe "init" is catching it. It then explained that the SIGKILL signal could not be caught. So I tried "sudo kill -s SIGKILL 1", but that didn't work either. Is "init" catching SIGKILL? Why won't "init" die?

Seaneseor posted:I'm running Ubuntu (Feisty) and I can't figure out how to kill the "init" process. Yes, init is allowed to ignore kill signals. Given that all processes ultimately derive from init, and killing a process generally kills its children, you can probably guess why that is.

KaeseEs posted:Why in the world do you want to kill init? If you want to turn off or reboot the computer via the terminal, try 'man shutdown'. I was just reading man pages and playing around with commands. It claims SIGKILL can't be blocked, so I tested out how dangerous this command could be by trying to assassinate the head honcho. Is there something about how 'kill' works that would logically prevent it from killing 'init'? Not because "it's a bad idea", but because "it's not actually possible"?

I have some files in a personal subversion repository, and I want to place them in a shared subversion repository - how can I do this while retaining the revision history for these files? I know there will be no conflicts between the files and anything that already exists in the destination repository. Is there a way to insert my files into the target repository so that if the current revision of the target repository is x, then revision y of the source repository becomes revision x+y of the source repository? I know I could script this if need be, but I'm hoping that subversion has some kind of built-in facility for this that I haven't been able to find yet.

Actually nothing cares about parent process dying, however process may be killed if its session ends, or if a pipe or socket closes as a result of another process dying. init's role of wait()'ing for orphaned processes is to prevent them from becoming zombies when they exit.

Seaneseor posted:I was just reading man pages and playing around with commands. There isn't anything "standard" the OS is supposed to do when init is killed, and there are some situations in Linux when kernel has to "spontaneously" execute a script that configures devices, what would be problematic without init being available. I guess, it would make sense to perform shutdown when someone with sufficient permissions tried to kill init, but even that usually requires init to do something, so it won't be immediately killed anyway.

teapot posted:Killing init... One can kill init with a live kernel debugger, other than that I do not think its possible with standard system utilities. From my experience of killing init on a Solaris 9 system, you end up with hundreds of zombie processes. Eventually you run out of free pids (due to zombies) and.. well you're pretty stuffed then.

This might be a pretty specific question, but I've googled around with no results. Has anyone gotten one of those PSX->USB controllers to work? I have one of those devices that can let you use two playstation controllers at the same time. Ubuntu Feisty gets the device at /dev/input/js0, js1 but doesn't detect any input. Really just throwing it out there, but hopefully someone has tried setting one of these up.

mirror123 posted:This might be a pretty specific question, but I've googled around with no results. This is totally unhelpful, but I got mine to work... sort of. In Edgy, I could get it to detect the controller automatically, but neither the analog sticks or the directional pad would work. When I upgraded to Feisty, everything automatically worked without my changing anything, except some programs will not recognize it, where others recognize everything on the controller perfectly. I remember there being quite a bit of info about this issue on the Ubuntu forums, so maybe there is something there that can help. Also, make sure the programs you use know to look at /dev/input/js0 or 1, and there are a couple calibration programs you can grab through Synaptic that may help.

While I like amarok, I find that it tends to not fully download my podcasts, usually cutting off the last five minutes or so for some reason. I've been looking for an alternate podcast fetcher, and I've tried hpodder and gpodder, but for some reason when I transfer podcasts downloaded with those programs, my ipod doesn't remember the track position (ie if I listen to another track, it begins the podcast at the very beginning). When I transfer podcasts downloaded by amarok to the device, track position is remembered, but even if I use amarok to transfer the podcasts downloaded by other clients, the position is not remembered. I see no option for either of these programs that would affect this, and I don't see any way to use amarok to manually set the "remember track position" option like you can in itunes. I've tried googling, reading documentation for these programs but I seem to be unable to find the answer. I assume I'm just not using the right phrase for "track position," but I'm kind of at my wit's end at this point. Any advice would be appreciated. edit: Also: the podcasts are showing up in the "podcast" option on the ipod, just not remembering track position. edit2: the magic phrase seems to be "remember playback position," but still no luck Pangaea Ultima fucked around with this message at 19:40 on Jun 4, 2007 |

Here's on that'll likely cause a fight: I need a linux distro that can host MediaWiki(and the stuff it depends on to run). The catch being is that the distro needs to be as lightweight as possible as I'll be running it in VMWare along with several other Virtual Machines(I'm thinking about ditching X server and all the toys it brings just to cut down on the headroom). Also it has to fit on one CD. If anyone has done something similar I'd love to hear from you.
