I have increased my RAM from 2 MB to 4MB, Vista can see most of it(it can't see more because it is 32 bits)but when I run Virtual box I can only see up to 2MB of memory.Is there anything I can do to fix this?
View 14 RepliesI have this directory with multiple images 'pics' and the size is 20mb and I want to make a .zip or .rar package of this directory but with an increased size so the .zip/.rar file will be 100mb, and then when you extract it the file size is the original 20mb. I want to make the result file bigger, no compress it. I need to put all the directory in one single file .zip or .rar but it has to weight more (100mb), maybe it can be done with another application. By the way, I have a centos 5 from command line.

I understand that in linux, the increased disk space is not automatically reflected but as I am new to this topic, I am not sure how I can go about doing this. how to see what's the available space and how I can partition(?) this.

According to Phoronix [URL]... aspm&num=1 (which seems to only test Ubuntu kernels) the problems should affect all users of the affected kernels, including Debian's, but that article provides a fix. I don't remember anyone here mentioning lower battery life and increased heat on their mobile platforms, though.
View 1 Replies View RelatedUsing Openshot, flowblade, or Kdenlive, when video gets rendered into mp4, it comes out at increased speed, both audio and video (seems like double speed but could be a different ratio)
When I play the exported mp4 with VLC for example, it shows the proper video length, not shortened. The video plays at high speed and for the second half of the video it just shows the last frame of the video until it runs out of time.
I have used Openshot extensively and have never had this problem, so I installed all the other video editors I could, and the problem persists (pitivi has a dependency problem so I haven't been able to use it).
I have tried several video players as well, all doing the same (VLC and Smplayer)

I installed F13 on a few ACER desktops with 4 GB ram. Recently I tried to upgrade the RAM to 8 GB. But after I plugged in the extra two 2GB ram sticks inside, the system still feels 4 GB. I had double checked with ACER and confirmed that 8 GB is supported by the motherboard. Is there any shortcuts to let the system recognize all the 8GB ram rather than reinstall the whole system.

I'm using OpenSUSE 11.2 with all the released updates are installed. I've got an Windows Xp SP3 on the same hard drive and it's works fine. S.M.A.R.T. says the hdd is 100%. A few days ago I realized that the boot time increased and the hard drive operations takes way too much time. So currently the boot sequence takes 11-14 minutes.
I've already tried to solve this problem but no effect:
1.) cleaned up the root directory to create more free space
2.) plugged the sata cable to another port
3.) changed from AHCI to IDE and reverse in BIOS settings
4.) added ahci, sata_nv into the /etc/sysconfig/kernel file and created a new initrd
5.) searched for problems in the syslog
Just to imagine how slow is currently the system/hdd:
I've just noticed that "nicing" long running computationally intensive, I/O unintensive, single-threaded executables on my system increases the CPU run time of those executables (as reported by /usr/bin/time as well as by wall clock) by a factor of 2-3 even in the absence of any load, i.e., "top" tells me that my program is getting 100% of a CPU. For example:
%coot 248: /usr/bin/time -p ./a.out > out
real 97.47
user 85.64

My system is running Ubuntu 7.10. If I run the same executable on two other machines I have access to -- one running Fedora 5 and the other Ubuntu 9.10 -- I don't see any discrepancy between the runtimes using nice and not using nice.
This behavior is executable independent, compiler dependent, and language dependent -- I'm seeing it across the board. I'm assuming I've somehow configured my system to behave this way, but I have no idea what I may have done. Also, this was the first time I'd ever done timing runs with "nice" (actually, "at"), so I'm not sure how long my system's been configured (if configured is the right word) this way.
I have implemented level 5 software raid (of 4 partitions on a SINGLE external hard disk). Implementing it on a single hard disk doesn't serve much purpose, I understand, but I did it for demonstration purpose only. The problem is when I read from the raid device into my laptop's hard disk, the time taken to transfer a 900 MB file is about 4 minutes (4 GB RAM) whereas the rime taken to transfer it from a pen drive is 43 seconds. Isn't raid supposed to work faster. However, the write to the raid device is faster than to a pendrive. Shouldn't it be taking data in parallel from the 3 partitions (as even a single disk has multiple heads) ?
View 2 Replies View RelatedMy Ubuntu system is occasionally becoming very sluggish. I'm running many things simultaneously and it's very difficult to tell which program is the culprit.
I suspect that the sluggishness is due to disk activity since the CPU usage is consistently under 50% on each of the 4 cores of the CPU, and over 30% of the 6GB of RAM are free.
Is there a tool that can show me in real time the number of disk IO operations per second and the amount of data read/written per second? Can all this info be broken down and displayed per process?

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?

View 1 Replies View RelatedII'm a front-end web developer, I've always developed on Windows with technologies like XHTML, CSS, Javascript and Flash, I've dabbled with PHP and MySQL. I am well used to Windows workflows and tools, from Photoshop to Notepad++, Filezilla and WAMP server stacks to After Effects, and a swathe more - but always on Windows.I'm at a point where I think I need to start seriously developing on a Linux box, specifically at the moment to create web apps based on Node.js, but compiling tools and programs has become a task I'm more frequently required to do.
My question? I need to get my hands on a user-friendly install of Linux, but which one? I need common interface developer tools (lists welcome) to replace... well as many tools I have on Windows as possible.I need to be readily connected to the internet, I need OS updates to not destroy my workflow by crashing the OS, as I've seen Ubuntu do to various friends. I want efficiency, I need to be able to customise what I need to in order to perform development tasks.I guess this could be a long list, but - I don't have practical working knowledge of the Linux OS, nor how it "compares" to Windows (excuse my faux pas). I'm obviously willing to learn, but I'm far, far more keen to just... continue interface development, just on Linux instead of Windows.
A friend of mine helped me set up a server which includes Squirrel Mail.It?s CentOS 5.3.I have a person who would like to access Squirrel Mail at remote sites.My questions is, I can create an account on the server which has KDE and the usual general applications and he would have the remote access Squirrel Mail but he doesn?t need nor does he want to access KDE or anything else on my server. He just want an account so he can use Squirrel Mail.
View 1 Replies View RelatedI have the impression that not that many people understand the scope and limitations of GNU General Public License. This is somehow my basic understanding of it. If I take a program covered under the GNU license, first of all I have the right to get the source code. Second, I can modify it at will. Third, I can redistribute it as will too but the new code will necessarily will have the same GNU license. This made me wonder how people actually can charge for software derived from Linux, for instance, Red Hat. Well, my impression is that they really make profit only out of services. In this thread [URL] I think I found a lot of confusion, even from a moderator (not intended to offend). Red Hat is based on Linux and it is necessarily covered under GNU. Somebody probably bought the program from RHE and can make it available at no cost.
Nevertheless, the moderator decided to warn the user. In this article [URL] it says the following:"Our training is not designed to promote vendor lock-in. Though these courses are based on Red Hat Enterprise Linux, the source code for [RHEL] is available to the community via the GPL [GNU General Public License]," said Red Hat spokewoman Leigh Day. This thread [URL] shows yet more confused people. Is there is a glitch in this type of license that prevents programs like RHEL to be redistributed for free? Why their license page doesn't mention GNU license? Or the problem is just that people get overwhelmed by this license and are afraid to be penalized and get paralyzed? By the way, RHEL is just the example. The key question is about the license!!

View 2 Replies View RelatedWhat is the general opinion of the Mandriva and Debian distros? Mainly asking what kind of user you consider the distro to be for (beginners, advanced, total newb, whatever), and whether you think they offer as much to an extremely experienced user as they would to a newb.Those are my two favorite distros, and I really like Mandriva a lot. I'm trying to pick one to stick with throughout, but I'm not really sure if Mandriva is too automated and Windows-user oriented like Ubuntu (I haven't really delved into the deeper aspects of Linux so I have zero experience in this area now). This might sound a little elitist but I don't want to be using Mandriva and just be automatically dismissed as a newb on first impression just because I'm using Mandriva (although admittedly I am a bit of a newb at the moment, I don't plan on staying one).
