A while back I had a Win2k box with just one non-Administrator user, this user being mike. For some good reason I reinstalled the system while keeping all my data files. After the reinstall I found that the new mike user did not own any of the old mike's files. I was able to fix this by logging in as the Administrator then changing the ownership of all of my files. User IDs on Linux are I think 32-bit integers, with the first user that root ever creates typically getting UID 1000, then incrementing by one for each additional user. Samba must maintain a mapping between the nearly random 64-bit GUIDs and the very non-random *NIX UIDs. Maybe your problem is that that mapping got messed up somehow when you upgraded to F16. I'm quite certain that there must be some way to have Windows accept an explicitly assigned user GUID, but I have no clue how to do it. Possibly such a feature is only supported for Windows NT Domains, which I haven't much experience with, I've only used Workgroups on my own Samba setups. -- Don Quixote de la Mancha Dulcinea Technologies Corporation Software of Elegance and Beauty http://www.dulcineatech.com quix...@dulcineatech.com -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
Re: Fedora 16 on MacPro
Does Fedora 16 boot on UEFI computers that do not have the legacy 16-bit BIOS? If not, you will need to install Bootcamp under Mac OS X with the Boot Camp Assistant. It is in /Applications/Utilities under Mac OS X. Bootcamp installs a 16-bit BIOS emulation as a 32-bit UEFI application. rEFIt, among other things, creates a Master Boot Record with a partition table that can be synched with the UEFI GUID Partition Table. Linux knows all about GUID Partition Tables. I do not know whether or not GRUB does. I think your problem is that GRUB wants the 16-bit BIOS. There is a 32-bit UEFI boot loader that may work for you, that would not require either Bootcamp or rEFIt. I looked into it a couple years ago, but it was not then considered mature enough for production use. Possibly it is now. I don't recall what it is called, though. -- Don Quixote de la Mancha Dulcinea Technologies Corporation Software of Elegance and Beauty http://www.dulcineatech.com quix...@dulcineatech.com -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
Re: gnomebaker [WAS: Re: question(s) on Brasero (maybe bug)]
The find command will easily determine the longest path in your directory tree. If ~/foo is the root of the tree that you want to burn, try: $ cd ~/foo $ find . -print ../paths.txt I expect there is some simple combination of command-line tools that would yield the length of the longest line in paths.txt, but I don't know what they would be. Instead I suggest opening it in your favorite text editor, then scrolling from the top to the bottom of the file. Whenever you see that a line has wrapped, make your window wider. You will likely have to move the left edge of the window offscreen. Once you get to the bottom of the file, scroll back up to find the line that just touches the right edge of the window. Copy that line to the Clipboard, then paste it into a new file. The wc command - for word count - will tell you how many characters are in that new file. Suppose it is called longest.txt: $ wc longest.txt I was mistaken when I said that the UNIX maximum path length was given by the MAXPATH #include file macro. It's actually PATH_MAX. The chances are pretty good that PATH_MAX is defined by a C Standard Library header on Windows. While PATH_MAX is a UNIX operating system concept, the Windows C Standard Library more or less attempts to be source-compatible with the simpler kinds of UNIX source code. If PATH_MAX for Windows doesn't turn up in a Google search and you don't have Visual Studio, there is a free-as-in-beer version of Visual Studio, but that would be a lot of stuff to install just to look up one line in a header file. Instead look for PATH_MAX in the MinGW headers. MinGW is a port of the GNU toolchain that produces Win32 binaries that is Free as in Freedom. If PATH_MAX is defined for Windows some MinGW header would have it. Quite likely you could find that header where you could get at it with a web browser without having to actually install anything. In general, UNIX allows directories to be nested to arbitrary depths. It's just that the total length of an absolute pathname is limited. If your file and directory names are shorter, your directories can be nested more deeply. A while back I discovered a bug in Mac OS X which was quite similar to this, but rather than file paths, OS X has something called a device path. The device drivers in the OS X kernel are connected in a tree structure, just like a filesystem heirarchy. At the root of the tree is the motherboard driver, at the tip of a branch for a storage device is the name of a filesystem. The company I was working for developed a storage driver for a client. On PowerPC Macs, our driver worked great. The identical driver source when compiled for Intel would not work at all on Mac Pros, the high-end desktop Macs. It did work on less-powerful Intel Macs such as my MacBook Pro. A great deal of debugging as well as poring through much of what is fortunately open source determined that OS X' Disk Arbitration daemon - the OS X equivalent of the UNIX automounter - was asking the kernel for the device path for the volume it wanted to mount. On Mac Pros, but JUST Mac Pros, the hardware was so much more complex and there were so many more devices in the tree that the resulting path would not fit in the fixed-size buffer that the system call allowed. I think that was 512 bytes. There was absolutely no way that length could be increased without breaking binary compatibility with existing programs. I reported the bug to Apple. They fixed it in the next build of the system somehow, but without increasing the size of the buffer that system call could take. I never looked into it, but I expect they worked around it by asking for the path one component at a time. That would make Disk Arbitration work just fine, but any other userspace program that depended on retrieving the device path would still break on Mac Pros, and would have to use the same workaround that Apple used for DIsk Arbitration. -- Don Quixote de la Mancha Dulcinea Technologies Corporation Software of Elegance and Beauty http://www.dulcineatech.com quix...@dulcineatech.com -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
Re: A general history question
architecture, or just could not be ported at all. To enjoy the full power of the GNU software, one had to drop a lot of dollars on an expensive UNIX computer, only to replace the proprietary software - which you had no choice but to pay a lot of money for - with the GNU software. RMS by this time was well into the development of HURD, the GNU operating system kernel, but in his usual fashion he wanted it to be light-years ahead of existing UNIX kernel technology. It was a long, long time before HURD could do anything useful at all. While it was developed with portability in mind, a kernel is a very least portable of any kind of software, because its source code depends on all kinds of minute, picky, arbitrary and often downright disgusting ways on the hardware that operates the kernel. Quite a lot of those hardware details are only available to developers who sign non-disclosure agreements. Even when the hardware interface isn't a trade secret, it happens all the time that the document is just plain wrong, or doesn't even exist! Eventually a Finnish Computer Science undergraduate student by the name of Linus Torvalds got really tired of waiting around for HURD to be usable as well as ported to the 80386 PC clones, so he wrote from scratch, and more or less all by himself, just about the simplest possible operating system kernel that would work more or less like UNIX did, but ONLY on 80386 PCs. That kernel was called linux, and it still is. Without the work of Richard Stallman, his colleagues at The Free Software Foundation, as well as countless others who contributed to the GNU source code, the linux kernel all by itself would have been largely useless. The original distributions were little more than the Linux kernel and the GNU user space software. That's why they should be properly known as GNU/Linux. The distributions of today come with a great deal more software than the kernel and the original GNU stuff. There are some who argue that we should call it Mozilla Linux because most of us spend most of our time using the Firefox web browser, which was developed by the Mozilla project. But the essential core of all of our distributions - not just Fedora, but Ubuntu, Slackware, Debian, all the Live CDs - is the GNU software. If you don't want to call it GNU/Linux instead of just Linux, it would really be better not to call it Linux at all. Call it by a name that gives credit to ALL of its contributors. For us, that is just Fedora. On my MacBook Pro, it is Ubuntu. I'm really beat, so I'm not going to address your question about the package managers quite yet. The package management is an important part of creating a usable distribution that end-users or system administrators can easily install, upgrade and maintain. In particular the mind-numbingly idiotic way in which all UNIX-like operating systems spread vitally important programs, code libraries, configuration files and other data files such as national language localizations All Over Creation makes it damn near impossible for anyone but an expert to UNINSTALL a program without the use of a package manager. The package managers didn't used to work so well though. It's not as bad these days, but it used to happen all the time to just about everyone that installation, upgrading or uninstallations would totally break a system. Debian did a better job with the packaging at first. Red Hat with RPM - the Red Hat Package Manager - had a well-deserved reputation for being totally brain-damaged. But those days are largely behind us. Not completely though; for no reason I can fathom, just last night, without doing anything at all, the Ubuntu Natty Narwhale installation on my MacBook Pro started reporting that it had broken dependencies that so far I have been at a total loss to repair.

Re: corrupted MAC error using scp
You may have flaky hardware. I once had bad RAM that was sensitive to the particular way the memory was accessed. The only problem it ever caused was that FTP downloads to that machine were *always* corrupted. I never, ever had any other problems. Memtest86 discovered the bad memory module, but I had to let most of its tests run for a long time before one of the later tests found the problem. Memtest86 got forked; there is also Memtest86+. The two tests are somewhat different now, as development has continued independently on both of them. For complete coverage you probably want to run them both. The tests will take a long time, but let them run to completion. These tests not just your memory, but also your CPU, memory controller and motherboard. You might also have some bad data on your hard drive. Every hard drive vendor offers boot floppy and often also CD ISO images for low-level diagnostic tests. Download the image for each of your drive, make a disk from it, boot the disk, then run all the read-only tests for each of your drives. From time to time it's a good idea to do a complete backup, then also do the destructive tests on your drives, then restore the backups. It exercises the bits on the drives, you see, thereby preventing them from getting flabby and out of shape. -- Don Quixote de la Mancha Dulcinea Technologies Corporation Software of Elegance and Beauty http://www.dulcineatech.com quix...@dulcineatech.com -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
Re: Samsung ML1640
Apple's Mac OS X provides driverless installs for both printers and image input devices. Of course the printers must have drivers from somewhere. OS X bundles that Gutenprint drivers, that are obtained from the Open Source community. I'm pretty sure that Apple either requires or maybe somehow convinces the printer vendors to maintain their Gutenprint drivers. From time to time I manually update all my third-party software on OS X; when I went to get the latest Epson driver, it said to run Software Update from the Apple Menu in OS X. So it can be done. Steve Jobs and Richard Stallman haven't always been the best of friends, but in general Apple has contributed a great deal to the Open Source community. I don't know because I never checked, but I imaging that Apple contributes patches to the Gutenprint maintainers. I don't have a clue how the image input is done. That's for scanners and digital cameras. That part doesn't come from Linux and is quite likely under Non-Disclosure Agreement, as many color image input device vendors have all manner of trade secrets around color management. It's not so good for Open Source, but for the end-user like my Mom, I bought her a nice digital camera for Christmas and It Just Worked with iPhoto on her iMac. There was no software to install. Having to hunt down and install drivers for arcane hardware is a Windows thing. There are lots of driver search databases, as well as binary driver installer websites for Windows.

Programming Language by Kernighan and Ritchey that I bought from the

I had some trouble at first with C's lack of a Boolean type. The
result is that I still have Line 7 of Page 41 memorized verbatim - as
well as the advice's precise page and line numbers:
True just means non-zero.
I'm pretty sure the much weightier second edition, which covered ANSI
C, contains the exact same statement.
Kids These Days. You simply have not lived until you have written
KR C - as opposed to ANSI C. That is C without prototypes;
you're lucky if you get a forward reference.
The following is perfectly legal KR C:
#include stdio.h
main()
int argc;
char **argv;
{
printf( Hello, World!\n );
return 0;
}
There was a period of a couple years of my early career where a
significant portion of my work was going through huge codebases to add
ANSI C prototypes and to declare ints explicitly rather than having
them just assumed where such assumptions were legal.

My friends Dave Johnson and Bob Polaro were two of Atari's first seven video game coders. If I remember correctly the Atari 2600 had a 6502 eight-bit microprocessor. They didn't even bother with compilers; one couldn't get anywhere with those games without using tightly hand-rolled assembler. There was a single eight bit frame buffer in which the graphics were rendered by rapidly varying the value in that byte in synchronization with the electron beam sweeping across the TV screen. The actual game processing would take place in many very small chunks during the horizontal blanking intervals, during which the dimmed beam would be swept back to the other side for the next line, or in fewer longer chunks during the vertical blanking interval. The coders had a choice of 1 KB ROM cartridges or 2 KB. One could get richer, more complex graphics and gameplay into 2 KB, but because the ROMs were so expensive to manufacture, the per-unit royalty that the coders earned was twice as much for the 1 KB cartridges! Dave told me once that it happened all the time that a game would go over 1024 bytes by just a few bytes, but that any changes that made the code fit in the smaller cartridge would screw up the timing for the graphics. The result of that was that the coders would often go insane in the middle of their coding projects. I don't recall what game Dave wrote to make his fortune, but he invested it first in Greene, Johnson Inc., then after buying out MIke Greene, founded Working Software, where he gave me my first retail coding job, writing Mac software. CoreEdit, the word processing engine of our QuickLetter specialized word processor, was also written in tightly hand-optimized assembly, but for the 68000. It was also the text engine for Apple's MacWrite. The people who wrote CoreEdit must have done some really hard drugs, but on the other hand I learned quite a lot about software architecture by reading its source. Bob made his fortune on Defender for the Atari, and is still in the video game business. He operates a mail order business on the side, where you can buy games directly from him: http://www.polaro.com/ These days though his games aren't in assembly, but in Java, Javascript and C++.

Re: any way to control disk order?
You can label the filesystems on each of your partitions. Then you mount according to the label rather than by the device special file. Let me ask google... http://tldp.org/HOWTO/html_single/Partition/#labels For years the order of SCSI disks was stable, but there was never any particular guarantee that the order would be any particular way. Then a new release of the kernel appeared that reversed the order! Since then the best thing to do has been to label your partitions.

Why does a web browser need raw socket access? Raw sockets are for creating your own protocols on top of IP - that is, alternatives to TCP and UDP. It's also for protocols that don't normally offer userspace APIs. One way to implement ping is to use a raw socket tp send and receive ICMP packets. All a web browser should require is TCP and DNS!

Re: OTish :D Colors of Cases for Fedora was: Re: Open Letter
It is true that flat-black materials are the strongest radiators. If you know the reflectivity of a material, you can measure its temperature from the flux of light (or infrared, for normal conditions) emitted per unit area from its surface. For a given temperature, the higher reflectivity will emit less. Even if you don't know the reflectivity - say, if you're taking an aerial or satellite photo - you can still measure the temperature by using a spectroscope to find the wavelength (or color) of the emission peak. As materials grow warmer, their emission grows both brighter and bluer. Thus hot stoves glow deep red, while lightning bolts are blueish-white and colossally bright. Interestingly, the physicist Planck derived that emission spectrum from purely classical considerations of systems of harmonic oscillators. I'm afraid I don't recall the derivation, but it has the curious property that it explains a fundamentally quantum mechanical phenomenon without the use of any quantum mechanics in the derivation. Purely classical! Planck's Constant h is found in the function that describes that spectrum, and can be calculated from that derivation. What is really cool is that Planck's Constant is also found throughout quantum mechanics. In QM h is almost always divided by 2 * PI, so to save writing we write an h with a diagonal slash through it, then drop the 2 * PI. This is pronounced h bar. Now here is where it gets really bizarre: h bar divided by two is the spin of the electron! That is, when we say that electrons are spin one-half particles, we mean that their angular momentum is h bar divided by two. Spin one particles like photons have an angular momentum of one h bar. It took me a long, long, long time to come to grips with spin. Spin is angular momentum, and charged particles that have spin exhibit the magnetic fields that one would expect from rotating electric charges, but spin is NOT rotation. Spin is also quantized. If we subject an electron to a magnetic field, its magnetic pole will either line up with the applied field, or opposite to it. Only these two choices are permitted; nothing in between. Bound states of particles are individual particles themselves. They obey all the same laws as elementary particles, just in more complex ways. Thus rotation arises from systems of lots of particles that possess some kind of spin. A friend describes spin as an irreparable tear in the fabric of the Universe.

Re: partition customization ....how do I ???
if you write I know everything about Linux/Unix in your CV .. I think it will not be considerable I've been running Linux on my own boxes since 1994 or so, and not just on x86 machines, but Old World PowerPC Macintoshes as well, both Debian and MkLinux, which was an Apple-sponsored project which built the Linux kernel around the Mach microkernel. Since 1999 or so I had been building my own kernels. For almost that whole time I would download tarballs from The Series Of Tubes to build for my own boxes. Quite often, stuff wouldn't build out of the box, so I had to hack it until it did. All this time I had quite a lot of good coding experience on my resume, including work as a Senior Engineer at Apple Computer. But try as I might - and I did try, many times - I was completely unable to get any kind of job working on Linux. None whatsoever! And why? I had absolutely no *paid* Linux experience on my resume! Finally, the solution occurred to me: I have a Skills section right at the beginning of my resume, that lists all my programming languages and the like. I added an item that listed every single Linux distro I had ever installed myself. There were quite a lot of them. Now the typical headhunter would still pass on me, because I had no actual paid positions that said anything about Linux. But a software engineering manager who was actually familiar with Linux, would look at that fact that I listed Yggdrasil among my distros, and understand instantly that I really did have real-world Linux experience. Yggdrasil ceased publication maybe twelve years ago. These days, anyone who even knows there was such a thing as an Yggdrasil distro clearly must be an old-school Linux Guru. I now have a job at Sony Ericsson, where I am a member of one of their Men in Black teams. Us Men in Black specialize in isolating and fixing the very most obscure and arcane bugs and performance problems in Sony Ericsson's mobile phone software, which in the case of my particular project, is Sony Ericsson's port of Google Android ... which is Linux.

Re: F12-i386-DVD iso won't burn properly
Try burning it with wodim. It's a command-line tool; you'll need to read wodim's man page, which will require a bit of study. One reason is that wodim is likely to succeed where other burners fail. The other is that wodim will give extremely detailed error messages if something goes wrong. I don't recall the precise command line you will need, so please do look up the man page, but it will be something like: $ sudo wodim -v speed=1 dev=/dev/cdrw -sao Foo.iso -sao means Session at Once, which is what you want if you're burning the entire disc from a single ISO file. Replace /dev/cdrw with your burner's actual filename - but /dev/cdrw is probably what you want.

Re: F12-i386-DVD iso won't burn properly -- SOLVED
The Chicken and Egg Problem for checksums was solved for the IP header checksum, and the TCP payload checksum back during the 1970s. When calculating the checksum, set the checksum field itself to zero. When verifying the checksum, skip over the value that is actually present. Perform the calculation as if it was actually set to zero. CD and DVD images could do the same thing.

The most one could claim is that a drive with no remapped sectors was in some way better than one with, but disk drives have supported sector remapping since the beginning of time. The very first hard drive I ever owned was a 135 MB (MegaBytes, not GigaBytes!) full-height 5 1/4 Fujitsu SCSI-1 drive that I put in a shoebox case. It came with a hardcopy listing of the bad sectors. My business partner was completely outraged! How could they sell us a drive with sectors that they know are bad? An alternative to remapping, which is support by most filesystems, is not to remap at all, but to mark filesystem blocks that contain one or more bad sectors as unusable. More or less, when the filesystem is laid down, a small invisible file will be laid over each bad sector. Remapping preserves the total number of sectors on the drive, but marking bad sectors as simply unusable avoids the problem of ever running out of spare sectors, at the cost of losing some of the drive's total capacity.

Re: Which backup program should one use? Was Re: Risks of backing up live mounted filesystems using dump(8)
I realized a while back that if one's filesystem is a rat's nest, then one's backups will be a rat's nest as well, as will be any files restored from backup. So I devoted a great deal of time to organizing all of the filesystems on all of my computers, and getting rid of stuff that did not really need to be online. This had the added benefit from freeing up hundreds of gigabytes of disk space. Now I have a two-level backup scheme. Say for Dulcinea's files, I will make a tarball of Dulcinea's source code, Dulcinea's financial books and so on, with the tarballs having the date in their name: Dulcinea_Code_2010-03-01.tar.bz2 I use the -MM-DD date format because an alphabetical listing will be ordered by date as well. This makes it trivially easy to get back just what I need should I ever need it. I have three filesystems on my F11 box: /backup0, /backup1 and /backup2. /backup0 is a partition on my internal RAID. It's not a proper backup, but just a convenience. I always backup to /backup0, then immediately rsync /backup0 to either /backup1 or /backup2, whichever is actually connected at the time. One of those two drives is on my desk, the other is in a safe deposit box. Once a week, I switch them. The reason I have /backup0 on an internal partition is to avoid having to make two trips to the bank when I switch. This isn't all automated yet, but I'm not far from there. I already do have continuous, automated backup for my Subversion repository. Whenever I check in new code, the Subversion hot-backup script backs up the whole repository and drops the backup onto /backup0. A cron job later copies it to the external drive.

Re: User to set CPU scaling?
More seriously, if there is a command-line tool that root would use to adjust the CPU scaling, perhaps it would work to add that command to the /etc/sudoers file. You would still need to use the sudo command to run it, but once having entered your personal (not root) password, you could issue more sudo commands for fifteen minutes without having to enter your password again.

Re: rsync, vs Partimage, vs other backup
I don't have any command line examples to give you, but I once used PartImage and GParted to successfully migrate a three disk RAID 0 NTFS filesystem on a Windows Small Business Server 2003 to a RAID 5. My friend set up the RAID 0 in eager anticipation of blazingly fast storage I/O, only later to realize that he had made the most important computer in his whole business three times more likely to fail unrecoverably. He asked if I could change it to a RAID 5 somehow. I used GParted to resize the filesystem so that it was definitely smaller than the eventual RAID 5 would be. I then used PartImage to image the NTFS filesystem into a file on a large FireWire drive. I used the RAID controller's BIOS to reconfigure the RAID 0 to be a RAID 5, then used PartImage to restore the filesystem from the FireWire drive onto the RAID. Finally I used GParted once again to grow the filesystem to use all of the available space. And it actually worked! I was so dumbfounded. Our Dear Friend Microsoft Windows Small Business Server 2003 did not appear to notice anything had happened at all. As an added benefit, my friend was left with a full backup on that FireWire drive.

From the installer, start a shell, then mount the root filesystem of your VM. There are two ways to deal with it at that point: one would be to edit /etc/shadow with vi or nano, and just eliminate the root password, that is, remove the characters between the two colons that delimit encrypted password field, so that it becomes just ::. After booting your VM normally, and logging in with no password, go and set a password. Alternatively you can chroot into the mounted root filesystem, and from there you can use the adduser command to set up a user for yourself. Put that user into the /etc/sudoers files so you can administrate the VM during a normal boot.

[SOLVED] Skype can't find libXss.so.1
And yes, I know this is the only post in this thread. I reported this problem with the first Skype beta for Linux, and was dismayed that it happened with the second as well. It occurs with both the RPM and the statically linked version: $ skype skype: error while loading shared libraries: libXss.so.1: cannot open shared object file: No such file or directory yum list doesn't find anything resembling the desired library. I suggested on Skype's Linux forum that they provide an RPM specifically for Fedora 11, but they still only provide one for Ten and Up and it's only 32-bit. Ubuntu gets 64-bit debs, what is Fedora, chopped liver? I made sure I had the i586 versions of all the dependencies. Their download page says it wan't libasound2; am I correct that on Fedora, that is the alsa library? Anyway I installed the 32-bit alsa library, and didn't get any complaints about it when Skype ran. I really, really wanted to use Skype on Fedora so I tracked down the missing dependency: on Fedora it is called libXScrnSaver. If you're running 64-bit as I am, it's not enough to have the 64-bit libXScrnSaver installed, you need to do: # yum install libXScrnSaver.i586 Despite the totally different library filename, it satisfies the dynamic link, and Skype launches right up! The only thing I had to do to get it working after that was to go into the Options and select my Logitech USB headset as the input and output audio device. This was really important for me because my business partner is overseas, and is really into Skype for Mac OS X. I could have used another telephony package for Linux myself, but it would have been much harder for me to get my partner to set up an alternative package on his Mac.

Re: recommendations for version controlling /etc on a new f12 box?
Subversion can provide automated continuous backup with a post-commit hook that calls the hot-backup.py script. The hot backup makes a compressed tarball of the entire repository, placed in the directory of your choosing. The name of the tarball is taking from the repository's revision number. (A Subversion repository has a single revision number for the whole repository, or effectively, if it is at revision 42, and you check in just one file, then all the files that were at 42 will also now be at 43.) The hot backup will optionally delete older tarballs, so if you like you can keep just a fixed number of them around. I use this for my own personal source code, in addition to a cron job that runs rsync on the directory where I drop the Subversion tarballs, to copy them to an external drive. Once a week, I swap that drive with an identical drive that I keep in a bank safe deposit box. I expect that it would work to put your whole /etc directory in Subversion if you tried. Alternatively, you could have a mirror of the /etc tree somewhere else, then use rsync to deploy updates when you were sure they were ready. I Got Religion about backups a little over a year ago, when I lost the third hard drive of my career. I managed to recover most of the files, but some were a total loss. I recovered all the files from my first failure, but the drive itself was a goner. The second drive started making these loud clicks, and was an instant, total loss. I'm not where I want to be with my backup system, as it is still mostly manually-operated, but I'm getting close.

Re: Moblin is dead, Fedora on netbooks?
Perhaps the Ubuntu Netbook Remix would serve your needs. Ubuntu also support ARM microprocessors, which these days are commonly used for mobile phones, but which soon will also be used for netbooks. The ARM architecture is vastly superior to x86 when power consumption - or battery life - is an important consideration. The Ubuntu ARM distribution is not yet really ready for use by the typical end-user, but should be straightforward to install and use for experienced Linux users. If you don't own an actual ARM microprocessor, you can run it under QEMU, using the qemu-system-arm command.

You know what I'd really, really like? I don't actually want those big fat pixels I went on so much about. Not At All! No, what I want are lots and lots of really *tiny* pixels, say 200 of them per inch. But I want my application software to still be able to get the sizes of things right, both on the display and on printed pages. That would require that drawing be done in terms of ruler measurements, and not in terms of pixel measurements. For type, the text size would be specified in points or picas. For everything else it would be specified in inches or centimetres. Cocoa on Mac OS X can do this; Cocoa drawing is always done using floating-point measurements, and not integer pixel dimensions at all. I eagerly look forward to the day that Apple starts shipping Mac laptops with 200 DPI LCD screens. Such screens are already being manufactured, but are only economical for small devices such as smartphones, because they are very expensive. But Wait! There's More! If Cocoa can do it on Mac OS X, then GnuStep can do it on Linux too. GnuStep is a source code-compatible clone on Cocoa. Both frameworks use the Objective-C programming language. On both platforms, the Objective-C compiler is - and always has been - GCC with the addition of the Objective-C front end. But Wait! There's Less! GnuStep isn't supported on Fedora because of some manner of Political Insanity. Cocoa and GnuStep software is always packaged in small directory trees known as bundles; all of the files that on a traditional *NIX box are spewed all over God's Creation and Then Some are, with GnuStep and Cocoa, all kept neatly in one small tree. To cleanly uninstall a GnuStep or Cocoa application, one just uses rm -r on the bundle directory, or drags it to the trash. But I'm afraid that just isn't acceptable to the Fedora Powers That Be. Until they can find some way to package GnuStep applications so that they too are spread all over God's Creation and Them Some, those who decide what software is to be included in Fedora, will not allow GnuStep applications of any kind on a Fedora box.

Hard-Wire GDM X11 Resolution?
I have a problem with my IOGear DVI/USB KVM switch, in which it fails to correctly emulate the connected monitor on DVI ports that aren't selected for display. That is, if my monitor is showing my MacBook Pro's screen, then Fedora gets the wrong display info from the KVM. If it is displaying Fedora, then the Mac gets the wrong info. In both cases it is easy to correct, but really annoying. It means that I can't boot both computers simultaneously, because the video on one of them will surely get screwed up. The problem that I have when the KVM is showing the Mac screen, is that the X11 for the Gnome Display Manager - the Fedora graphical login - has a much lower resolution than my LCD monitor possesses. You know what happens when you lower the resolution on an LCD - its get all blurry. Logging in and then trying to set the resolution with Gnome's display preference does not work at all. What does work is to log in, then immediately log back out. The new instance of GDM that is created after logout will have the correct resolution. Now my question for all of you: Is there some rational way that I can just hard-wire my X11 resolution to a single, fixed value? I have an LCD display, and I don't use any other monitors. I have no reason to ever want any resolution than the fixed resolution of that one display. Now and then I check IOGear's website for KVM firmware updates, but so far they haven't released any. Some day I'll contact their tech support. What is really odd is that Mac OS X has a completely *different* problem: OS X sets the display resolution correctly even if the KVM is showing Fedora, but the OS X login user interface will be on my MacBook Pro's internal screen. If my Mac boots with the KVM connected to it and not Fedora, the login UI is correctly displayed on my external LCD display. To fix the Mac problem, I yank the DVI cable off the Mac, wait for the the built-in screen to readjust itself, then plug the DVI cable back in. At that point the login screen will switch from the internal screen to the external one. Thanks!

Re: Help Diagnose Slow Disc Access
All of the hard drive vendors provide disk drive diagnostic tools, that are able to access vendor-specific - and undocumented - firmware in their drives. This diagnostic firmware is able to diagnose drive hardware problems in a much more thorough way than the vendor-neutral S.M.A.R.T. is able to. These utilities are always provided in the form of DOS boot disk images; one generally has a choice of making a floppy or a CD-ROM. Some of the vendors also provide diagnostics that can run under Windows. But the advantage of the DOS boot disks (besides not having to run Windows), is that you can test your boot drive without having to disconnect it, and the test is performed on a completely quiescent system. The diagnostics are all quite easy to use. Generally there is a short test that just queries the diagnostic firmware, and a long test that does a non-destructive test by reading every sector on your drive. Some of the diagnostics also include a drive exerciser which tests the drive more rigorously by reading random sectors all over the drive. Finally they all have a destructive test, in which the diagnostic writes zeroes to every sector of the drive. No matter what, if you think one of your drives might be flaky, back them both up at once, before doing anything else. Being fully backed up also gives you the advantage that you can then run the destructive sector-zeroing test. I feel it's a good thing to do in any case, just to exercise the bits. A while back I downloaded all the diagnostics from all the drive vendors, and burned a CD for each one. I also keep them around on a filesystem where I archive all my software installers. They're good things to have on hand. I realize that you're using a parallel cable. But a note for anyone else reading this, who wants to test an SATA drive. Recent versions of these utilities do support SATA, but they are only able to do so by embedded device drivers for every SATA controller in existence, in an executable that starts up from 16-bit DOS. My experience with the use of these for SATA drives, is that the diagnostics worked just fine for SATA controllers that were integrated with the motherboard. But when I tried to use a PCI SATA controller, the diagnostic couldn't find the drive.

ATI Radeon vs nVidia 3D accelleration
How well is radeonhd's 3D accelleration expected to work in Fedora 11? I did a yum update recently. My box at work and my box at home are both Core 2 Quad Xeons. My work box runs Ubuntu 8.10 and has an nVidia card - lspci says: nVidia Corporation Device 0658 (rev a1) lsmod shows that it's using the nvidia driver. Is that the closed-source driver? My box at home runs Fedora 11, with an ATI Radeon card. I don't recall the model, but it has 1 GB of RAM and occupies the space of two PCI slots, with a big fan, so it should be a fancy, powerful card. However while the nVideo card at work can run glxgears at a frame rate of 5000 FPS, my Radeon can only do 300! lsmod tells me that the DRI drivers are loaded. Is there something I can tweak to get faster 3D, or is this the expected performance for the current radeonhd driver? Thanks!

So you should not expect the performance of accelerated graphics to depend on the CPU model. Not too much, anyway. That depends on the application. Some 3D accelleration is implemented by having the CPU optimize the input to the GPU, so that there is less for the GPU to render. lsmod shows that it's using the nvidia driver. Is that the closed-source driver? Yes. Ah that is why my work box has such a high framerate - the closed-source nVidia driver can use undocumented features that have not yet been reversed-engineered for Open Source use. However while the nVideo card at work can run glxgears at a frame rate of 5000 FPS, my Radeon can only do 300! The glxgears utility is not a good benchmark. Better try out some real life stuff like quake3, nexuiz, extremetuxracer, or such. :-) Or those more dull things like googleearth and compiz (if your reflexes are too bad for gaming). Heh. Actually I did know that, as I came across this page just a couple weeks ago: http://wiki.cchtml.com/index.php/Glxgears_is_not_a_Benchmark On my nVidia work box, Extreme Tux Racer had a framerate of 100 to 130 at 1280x1024 (in a window, not full screen). I won't be able to try my Radeon home box until this evening. Is 3D actually turned on? You can have both hardware and drivers which support 3D, but have xorg.conf that disables it, or something like that. You can check for direct rendering like this: glxinfo | grep direct If it says yes, then all should be well. :-) Ah, I didn't know about that - thanks. When I try glxinfo | less on my nVidia work box, it lists a whole slew of GLX extensions. Even if my Radeon has 3D turned on, it probably doesn't support as many such extensions as the proprietary nVidia driver does. There are probably some tools out there which measure frame rate and do proper serious benchmarking, but I don't know any. Actually there is a very good 3D benchmarking tool for Linux, which I've been intending to try: http://www.phoronix-test-suite.com/ My understanding is that the Phoronix Test Suite doesn't do the 3D in itself, but serves as a test harness for running lots of other video software. The installation instructions says that Fedora has a phoronix-test-suite package, if you want to try it out yourself: http://www.phoronix-test-suite.com/documentation/2.4/install.html Don Quixote -- Don Quixote de la Mancha quix...@dulcineatech.com http://www.dulcineatech.com Dulcinea Technologies Corporation: Software of Elegance and Beauty. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
Re: Zen kernel, what are advantages if any?
As for TuxOnIce, you can hardly blame people for wanting software which will not only suspend but includes resume. Suspend/Hibernate are pretty broken, for many people TOI works. How true! Thanks for pointing out TuxOnIce. I have been very frustrated by the stock hibernate on my F11 box. I can hibernate OK, and resume mostly works, but after resuming I am unable to use the network. Fiddling with ifconfig (down, up and explicitly configuring it) doesn't help at all. So I just have to shut down completely rather than hibernate. And for many people ndiswrapper works (for some values of works). That doesn't make it the right way to solve the problem for everyone. Ideally whatever TuxOnIce has done to make hibernate work reliably will be merged into the kernel.org source. But that takes time, and work.

Core 2 Duos are 64-bit processors, so you can install the 64-bit Fedora. However, all the x86_64 (aka AMD64) CPUs can run in 32-bit mode. So you can install the 32-bit Fedora instead if you choose. My MacBook Pro is a Core Duo, but not a Core 2 Duo. The Non-Two Core Duos are 32-bit only, so when I finally get around to Linuxizing my laptop, it will have to be 32-bit only. When one has a choice of either 32-bit or 64-bit, there are certain advantages and disadvantages to each choice. The main advantage of 64-bit is that, if your motherboard supports it, you can install more than 4 GB of memory. That would enable you to run lots of programs simultaneously without any virtual memory paging. I have 16 GB in my F11 Core 2 Quad Xeon box, and I never, ever have to hit the swap file. Even with less then 4 GB of memory, it is possible for software to run faster in 64-bit mode than 32-bit mode, because the x86_64 Instruction Set Architecture adds some general purpose registers that aren't present in 32-bit. Whether that helps your particular situation would depend very much on the software you use. (Tastes Great! Less Filling!)

Obsessive geek types could set the resolution very high to fit more source code on the screen... ... while those with poor eyesight could set the resolution very low, to make text larger and so easier to read. It doesn't make any sense at all of LCD displays though. One just about always wants to use the physical resolution of the LCD pixels. What I've been looking for, for a long time, yet am unable to find, is a very large, yet LOW resolution LCD display. What I would like to see are great big fat square sharp pixels, with great big, sharply defined and completely non-antialiased text. I spend all day long working in front of a monitor.

Re: 32bit support on 64bit Linux
There is a single yum target, that will bring in all (or most) of the 32bit libraries and things that are needed to run 32bit applications on 64bit Fedora. It is also possible to install just the specific 32-bit libraries that you need. That's what I did when I built ZooLib for 32-bit under 64-bit Fedora. (http://www.zoolib.org/) If you're building a 32-bit program from source, just try to build it before installing any 32-bit libraries. The link will fail because it can't find a bunch of stuff. Try to figure out what 32-bit yum packages satisfy just the first few complaints, then install the packages and try again. After a few rounds of this you'll have pretty close to just the bare minimum of libraries needed for that one program. If you have a binary executable, and not the source, then ry running it. It won't run because it can't find a bunch of libraries. Install the first two or three libraries that it complains about, then Lather, Rinse, Repeat. In general a runtime library named libfoo.so will have a yum package called libfoo.i386 or some such, and a development library named something like libfoo-dev.i386. You only need the -dev libraries if you're developing from source - these include the header files, that aren't needed for runtime support. I'll send you my bill in the mail.

Re: How do I put Multiple live distro's on a USB flash drive.
On Sat, Jan 30, 2010 at 8:27 AM, tux t...@pantherfish.com wrote: I have an 8GB flash drive that I would like to put multiple Fedora Live CD's on. (KDE,Gnome,LXDE,XFCE, FEL, Games and Edu,Third party spins, etc. ) Does anyone have any advice on how to do this I think it should be straightforward to do this, but you'll need to do it carefully and methodically. I do something like this with my VirtualBox disk images. I put them in physical partitions for efficiency, but sometimes copy them out to regular, uncompressed files then convert them to sparse images then compress them with bzip2 for backup. I works real well, but is tedious and error-prone. I need to automate it or Imma gonna overwrite my /home with some WinXP disk image. Anyway what you need is a Master Boot Record on the first 512-byte sector of your USB stick. Make one small ext2 primary partition for /boot, then a logical partition for each of your live CDs. The MBR only allows four primary partitions, but only /boot needs to be a primary. So you can make one primary, then one extended. Within the extended you can make as many logical partitions as you like. The primary and extended partitions are stored directly in the MBR, towards the end of that first sector. The extended is divided up into logical partitions, with their positions and sizes specified in a linked list that is also inside the extended. I don't know the details but I would imagine each partition link element is just before each logical partition. Use ls -s to get the size of each of your LiveCD images in kilobytes. If they are compressed, decompress them first. Multiply the size in kilobytes by two to get the size in 512-byte sectors. When you partition your stick, use GNU parted - NOT GParted! Not the GUI partitioner, just parted, the command-line tool. Set the size unit to sectors. Use parted's help to get the exact syntax but I think you just use: unit s Create a /boot partition as I said with ext2. I don't think it needs to be very big - a megabyte or two would be plenty. It won't contain a kernel as /boots usually do. Create a logical partition for each of your LiveCDs. Make each partition EXACTLY the same number of sectors as the LiveCD image that will go into it. It's OK if the partition is bigger - it just wastes some space. Make sure it's not smaller. It's really best to be careful and methodical and get the size exactly the same. You'll need to figure out the /dev entry for your USB stick. Chances are that it is /dev/sdb though - the second SCSI drive. USB Mass Storage is built on the SCSI Architectural Model. /dev/sda would be your boot disk if you're using SATA, SAS or Parallel SCSI. If your boot disk is /dev/hda, then it is Parallel IDE. If that's the case then your USB stick is probably /dev/sda not sdb. *** Get It Right Or You'll Be Sorry! *** If your stick is /dev/sdb, then the stick's /boot partition is /dev/sdb1. Your LiveCD partitions are numbered starting with 5, because they are logical partitions - /dev/sdb5, /dev/sdb6, /dev/sdb7 and so on. Partition numbers 1 through 4 are reserved for primary and extended partitions. Now use the dd command to copy a LiveCD image into a partition: $ dd if=FedoraLive.iso of=/dev/sdb5 bs=512 That copies the FedoraLive.iso input file to the first logical partition as the output file with a block size of 512 bytes. Most storage devices have physical sector sizes of 512 bytes, so you are required to read or write them in integral multiples of 512. There's a couple pieces remaining though that I can't explain for you, but I can give you some hints: It *should* work to set up grub to chainload each of the LiveCD partitions. That should work just the same as if you were booting MS Windows. Grub would load the first sector out of the desired partition then run the boot loader found therein. What I don't have a clue about though is that booting a CD uses a package called ISOLINUX. You don't want ISOLINUX to boot a USB stick. There is another package for that, but you'll have to dig it up somehow as I don't remember. Basically what you need to do is replace the ISOLINUX on each partition with whatever the equivalent is for a USB stick. If I recall correctly the way ISOLINUX works is that it finds a Linux filesystem image in a single file on the CD, then it loads it as if it were a filesystem on a real hard disk. You should be able to use that same image file, but you will have to use some other software than ISOLINUX to load it. Hope That Help!
