Run something like emerge --noreplace =gentoo-sources-2.6.38-r1 to add the kernel you want to keep to your world file, or just add the kernel with it's specific revision to the world file manually.

Yes; mdadm RAID-1, with LVM on top, as in the Gentoo how-to: http://www.gentoo.org/doc/en/gentoo-x86+raid+lvm2-quickinstall.xml Are you looking for a little redundancy or a lot of redundancy? I'm just speculating at the moment, from a dabbler's point of view; what benefits would accrue from switching from RAID-1 to RAID-5 or above? And, in particular, what are the comparative virtues of the Samsung disks? My understanding is there's nothing more reliable than RAID1. mdadm allows N-wide RAID1. My RAID1's are currently 3-drive. Typically the higher RAID numbers are for trading off storage space, redundancy and in some cases throughput. My 5-drive RAID6 gives me (again, my understanding) equivalent redundancy to a 3-drive RAID1. I can lose 2 drives in either RAID before I risk losing everything with a 3rd drive failure, but I only get the storage of 3-drives. A 5-drive RAID5 would lose everything with 2 drive failures but gets 4 drives of storage. As for Samsung drives I have no experience. However one common problem I read about again and again is a RAID user who loses 1 drive and then, while in the process of fixing the RAID, loses a second drive. Most of us (myself included) buy identical drives all at the same time from the same vendor. This means all the drives were likely from the same manufacturing batch and, if they are drives that will fail at all then the group will likely experience multiple drive failures. The underlying idea of RAID is that the drives are not likely to fail at the same time giving us time to fix the array. However, if /dev/sda fails the chances of /dev/sdb failing is higher if they were built at the same time in the same plant. Reading the mdadm list for the last couple of years it seems that many folks running data centers intentionally buy drives from multiple manufactures, or drives of different sizes from the same manufacturer, hoping to lower the chances of multiple failures at the same time. What I did myself was buy 5 drives initially, 3 from Amazon, 2 from NewEgg. For spares I then waited 2 months, bought one more drive, and waited another 2 months and got one more. In my case all my drives are WD RAID Edition drives which have higher reliability specs than the commercial drives. (And are more expensive and smaller) As for hardware RAID the risk I hear about there is that if the controller itself fails then you need an identical backup controller or you risk the possibility that you won't be able to recover anything. I don't know how true that is or whether it's just FUD. Cheers, Mark

The new meds aren't perfect but it is better. When I go back, he may change it to another med. He just wanted to try this first. It does sort of help me to get a better grasp on things tho. Sort of weird in a way. That part is like a side effect. :/ I'm just needing to find me a good LARGE drive to put in here. I'm checking out the reviews but it just seems most have issues. May just have to buy one, work the stuffing out of it with a script or something to see if it holds up. I see some of the large drives spin slower, some a lot slower. Given the density of the data, are they about as fast as a drive that spins at 7200? My main drives for my OS and the large drive I already have turn at 7200 rpms. I'm just curious if that would be slower or because of the density of the data, it doesn't matter. I get about 80 to 100Mb/sec on my current drives. I have 3gbs/sec drives which is what my mobo maxes out at. I thought about getting a 6Gb/sec just in case I upgrade my mobo later. My data drive mostly has audio/video stuff but does contain pictures I took with my camera and some documents, mostly saved web pages or OOo stuff. My 750Gb drives plays audio/video stuff just fine, even the HD stuff. I just wouldn't want to get a drive that is slow enough to cause pauses and such. I see newegg has 3Tb drives too. he he he he O_O Thoughts? Dale Good thread Dale. I've been busy this week so I finally read the whole thing, start to finish, this morning. Good LVM info which I expect I'll use one of these days myself. Personally II think one thing you might want to consider, given your concerns about not losing important personal data, is to investigate RAID with the same level of focus that you are doing with LVM. Instead of buying very large drives (3TB) you can build a large RAID6 or RAID5 out of smaller 500GB or 1TB drives. Personally my home compute server, which runs 4 copies of Windows 7 in VMWare and Virtualbox for trading in the futures market, is set up this way: - Five 500GB WD RAID Edition physical drives - /boot is just a 100MB partition on /dev/sda, but I've saved more partition space on other drives with various kernel images should /dev/sda fail. - Gentoo is on a 50GB 5-drive RAID1. That's a LOT of redundancy. I can technically lose 4 drives and the system continues to work fine. For the OS that's essentially unkillable short of someting like a power supply failure taking out all the drives or the MB. - /home is on a 5-drive RAID6 using 50GB partitions. That gives me a total of 150GB storage personally for my pictures, videos, code, etc., and allows 2 drives to fail without losing data. - /VirtualMachines is on a 5-drive RAID6 using the remaining 400GB on each drive, so that's 1.2TB with redundancy of a 2-drive loss being protected. I then have a few external eSATA hard drives that I use for backups. /home to one pair, /VirtualMachines to another pair. I think if I was to set up this system from scratch again I might consider one large RAID6 using 450GB and putting /home in one LV and /VirtualMachines in another. The advantage would be that over time, if my personal needs increased, I could resize the LVs more easily than resizing the RAIDs. (Which is also possible but beyond the scope of this thread...) Anyway, it's just another idea about how you can use the same hardware in a different configuration. Five 1TB drives as a RAID6 gives you both 3TB of storage as well as far more reliability. One 3TB drive by itself can die and everything is gone. Congrats on your learning experience and I hope it continues to be successful for you. Cheers, Mark

I personally doubt that ext4 vs ext3 will make any difference. I use both myself. I wouldn't personally touch any new file system type when trying to learn to do RAID. Save that for some future date. Unfortunately neither link is responding as I write this, but my recent (last 6 months) experience with the Gentoo RAID documents is that none of them result in a completely working system first time through. (Again, I cannot look at these links right now so please excuse my not knowing about any recent changes.) 1) They are all based on the oldest SuperBlock 0.9 format which, if I remember correctly, is not the default SuperBlock format that mdadm creates these days. 2) I was able to build a SB-0.9 system using the same docs. I was only able to build a working SB-1.2 by also including an initramfs: http://en.gentoo-wiki.com/wiki/Initramfs Pay special attention to note about building certain things static or the initramfs won't work for you. Also, include all the tools you can that will help with debugging why you cannot mount the root file system. My experience is that you won't be able to for the first day and you'll find the tools invaluable in getting it worked out. 3) It might be frustrating, but I'd suggest some testing of the RAID before the actual install. Boot the install disk, build the RAID, then learn to use mdadm examine detail commands to understand then names your RAIDs have. Pay attention to what the name of the machine will eventually be. Consider renaming the RAIDs before the real Gentoo install so that when you boot the real install it can find them. I run RAID these days on almost all my machines.

James James, Depending on what you are putting onto your RAID watch carefully what choices you make for SuperBlock type as well as being aware of possible md name changes between the install environment and your first real boot. I cannot comment on BTRFS and whether it's a good thing to use with LVS. I've seen varying reports so if this is a learning install then do what you want and have fun. If it's intended to be an in-service machine ASAP then possibly look around for more info on that before starting. Good luck, Mark

After the emerge (list below) I also re-emerged the virtualbox-modules-3.2.12; logged out and rebooted. Now when I try to start virtualbox, it lists the guest machine as inaccessible; no other information is provided by the virtualbox startup window. I would appreciate inputs on how to fix this. Thanks, -- Valmor A couple of questions: 1) Is the machine on a RAID partition or some other form of storage which, for whatever reason, isn't mounted?

The Linux kernel guys haven't made my drive D E disk interfaces 100% reliable as of yet so in my case I might have to reboot once or twice to get the drives recognized. 2) What kernel are you using.

Using the least number of layers of abstraction you can get away with is a perfectly valid criteria. What I was pointing out was that informal polls of users with a sad story to tell is not a very effective way to conduct research. People say all kinds of things that just aren't true. There's an elephant in this room. The number of actual layers is greater than just LVM plus FS. It's whatever the BIOS (or a reasonable substitute is doing), plus the drive firmware, kernel driver(s) - there's more than one of those - plus any RAID in use (hardware or software) and finally the file system. That's a lot of layers, a lot of code, a lot of opportunity for people to reveal the extent of their lack of knowledge. I've often heard it said that code like ZFS and brtfs eliminates several of these layers therefore it's technically a better option. That may be true, but let me just point out that whatever LVM+fs+other_stuff is doing as separate chunks of code also gets done by ZFS etc. You just don't see it, and just because it's abstracted away doesn't mean it's not there. I'll add this. Alan if I recall correctly runs a lot of systems. He has a boatload of experience using all sorts of software/hardware. Me, I don't. For the longest, I had one system and that was it. If I upgrade my kernel, LVM, or some package that LVM depends on and I can't boot, I'm screwed. If I can't boot, I can't google anything to find out how to fix it. I also don't know enough about LVM to fix it myself. Since there is so many layers of things that can already go wrong on a system, adding one more layer that can be complicated only makes a problem grow. I'm sure Alan and many others could go out and buy or build a new system and put LVM on it and fix about any problem that comes along. Thing is, there are others that can't. Add to this that when I was thinking about using it, I read where a lot of people, for whatever reason, couldn't get it back working again and lost data. For me, I don't care if it was LVM itself, the kernel or some combination of other things, if I can't boot or lose data, the result is the same. I can fix a kernel problem, a broken package but if LVM fails, I'm stuck. That said, I now have a second rig. I may at some point use LVM because I can always go to the other room and use my old rig to get help. I already have a 750Gb drive that is about full of pictures, I got a camera and get a little happy at times, and videos I have downloaded, everything from TV series to stuff off youtube. I may buy another large drive and use LVM or something to give me more room since I really don't want to have to break up my filing system across two separate drives. I won't consider putting the booting part of my OS on LVM tho. Of course, I did see a 3Tb drive on sale the other day at newegg. o_O That would last a while. ;-) Dale :-) :-) Dale, I understand your position and concerns. While I have a number of systems, I have little time or patience for dealing with a lot of this stuff and LVM has been one of them. One thing I'm considering to try out LVM is a second Gentoo installation on an already running system. It will either be a 50GB partition of its own, or a Virtualbox VM. I'd do the normal Gentoo install for LVM, figure out how it works, etc., and then decide if I want to use it in the future.

Walter, You have confused me. First you indicate that multilib is needed for WINE. Then you indicate that you had to use the 32 bit mixed mode (no multilib) under qemu-kvm, and and then install WINE under the 32 bit qemu. So if you were installing a system, just to run wine, would it be multilib or hybrid (64 and 32 bit) ? James James, 1) Wine is 32-bit 2) Walter had a 64-bit only system 3) Walter had 2 choices: a) Wipe the system and start over making it a multi-lib system b) Create a 32-bit chroot He chose b). It's not possible to 'install a system to ONLY run Wine', but if you want to run Windows apps you have 3 choices: 1) Install 32-bit Gentoo on your 64-bit hardware. Not very interesting to me. 2) Install 64-bit Gentoo with multi-lib support. This is what I do, although I don't run Wine anymore as I use Vbox VMware. 3) Install 64-bit Gentoo without multi-lib support and run which in a 32-bit chroot. Double the Gentoo maintenance because you are now required to keep both the 32-bit 64-bit installs up-to-date. Hope this help.

I suspect the purpose of the 32-bit DVD is to support those boxes. As evidence of the growth of 64-bit machines in at least the vocal part of the Gentoo users (those using the user's lists) I started running 64-bit Gentoo about 5-6 years and at this time no longer even own any (working) 32-bit machines. Up until about 3 years ago the Gentoo amd64 list had all the 64-bit specific question traffic. As of today that list is almost totally quiet implying that nearly all 64-bit users are just using this list and most folks see no distinction anymore.

I may be wrong but I think a default Gentoo 64-bit install to the level of @system booting the machine and little at all in /var/lib/portage/world won't install the 32-bit emulation libraries.

[gentoo-user] keyboard lighting control?
Is there either a kernel config option or additionally some application that allows me to turn on and off the lights underneath this groovy new laptop's keyboard? They flash on when booting, and work in Windows, but I don't know how to control them in Linux. I haven't found any function key that does it in hardware so I assume it's possibly an ACPI type thing or something else? Thanks, Mark

If at first you don't succeed, redefine success.
I see the same thing here. I'm in the middle of an install so I create
/dev/md3 to build my RAID1. I build it, install, chroot, do the work,
install grub, reboot and it's md126. The problem is that the machine
name changes between the install and the reboot.
The change apparently has something to do with a decision to only
assemble Version 1.+ superblocks with the right name when the name
field matches something in the superblock.
Apparently you can set up the naming as you wish using
mdadm --update=homehost
mdadm --update=name
but I don't feel confident enough yet to do it.

Re: [gentoo-user] dual boot RAID

Dual boot linux with Windows7 all on a Raid (0) array? I found a bargain, MSI MS-7596 (760GM-E51) motherboard. But my only MSI motherboard experience, left a very bad taste in my mouth from years ago. BIOS nightmare Anyway the motherboard doc says it supports (Sata-II) RAID 0 1 0+1 or JBOD mode by AMD SB710. This does not sound like a good choice of MOBO and anyone with any raid/gentoo/ experience on a MSI motherboard (MS 7596) or such would be appreciated as to you opinion. I usually specify ASUS, as over the years, I've had very little trouble. Dual 2T RAID 0 drives with windows and gentoo is my goal; and any recommendations are most welcome. AMD is the only processor I use tia, James I use Asus also. Actually, I'm installing Gentoo on a 2-disk Asus laptop today. (G73JW) Seems pretty nice so far. I've left the original Win 7 installation on the first hard drive, but sized the partition down. I will set it up for dual boot later. For now I change the drive boot order. I boot from the second hard drive leaving the original Windows partitions completely alone, and then have RAID1 on both the drives where Gentoo is installed. I guess the one thing above I'm not clear about is your choice of what appears to be RAID 0? RAID 0 is hardly RAID as there's no redundancy. Lose 1 drive you lose all your data. Also, if you're doing Linux RAID then the MB chipset RAID stuff is immaterial. You're going to do it using mdadm software RAID which then has no impact on what Windows does. Processor choice makes little impact on how Linux RAID works. Faster is better. AMD or Intel is your choice. Good luck, Mark

[gentoo-user] mdadm --monitor email
Hi, I'm curious about setting up my compute server to monitor RAID array status and have it email me information at my GMail account. Does anyone have info on setting this up on Gentoo? In general I'm following: http://en.gentoo-wiki.com/wiki/RAID/Software but it seems there are a few holes in my understanding. 1) In the /etc/mdadm.conf file I see the following: # # When used in --follow (aka --monitor) mode, mdadm needs a # mail address and/or a program. This can be given with mailaddr # and program lines to that monitoring can be started using #mdadm --follow --scan echo $! /var/run/mdadm # If the lines are not found, mdadm will exit quietly #MAILADDR r...@mydomain.tld #PROGRAM /usr/sbin/handle-mdadm-events - Easy enough to change my email address, but how does it get mailed? Is this what ssmtp is for? ssmtp is installed as a dependency of sudo, but I don't use it explicitly. Do I have to have a real domain in my name to get GMail to accept this? - Currently have have no program called /usr/sbin/handle-mdadm-events. Is this just a placeholder for whatever program I choose as a mailer, or is this intended as some program that takes real action in case of a problem? 2) I'm making the assumption that running rc-update add mdadm boot, as shown in the link above, is the way to get this started once configured properly? 3) I note that the test command listed in the link above doesn't work: c2stable ~ # mdadm -Fslt mdadm: option -l not valid in monitor mode c2stable ~ # 4) Assuming I do get this working, while testing can i have the program email me every 60 minutes whether things are good or bad, just to test that it's actually working and getting results?

[gentoo-user] vmplayer not working after xorg upgrade
This morning I did an xorg-server upgrade which included IIRC 33 files
total on my system. After the upgrade I am unable to run the vmplayer
app. The GUI never comes up. If I run it in a terminal it seems to die
quietly after about 5 seconds. There are no additional messages in
dmesg. The machine is _mostly_ stable. The machine is emerge -DuN
@world/revdep-rebuild -i clean at this time.
I tried upgrading to 2.6.37 a month ago but had this same problem so I
fell back to 2.6.36-gentoo-r6 which has been working. At the time I
was using an ATI card so I'm going to try 2.6.37 again after I post
this.
All Virtualbox VMs are running fine.
Can anyone suggest other things to look at? The only purpose this
compute server has in life is to run many VMs for me so this is a big
killer to my afternoon.
I did install mailx/smtp stuff this morning prior to checking these
VMs. I doubt that's involved, but maybe who knows...
Let me know any questions or requests for more info.
Thanks in advance,
Mark

Dunno. So I poised this question on gentoo-doc and got this encouraging response from *JOSH* snip James Given that some folks on here have ran into USB drives changing the order of partitions, I think this is a good idea. If needed, they could at least introduce the subject then have it link to another page. Even if it is the simplest label of using boot, root and such labels and maybe a mention that there are other ways to accomplish the same thing. I ran into this issue a while back when I added a hard drive and it was not easy to work with. When I boot a CD/DVD, it sees them as hd* instead of sd* so that didn't help since the OS kernel sees them as sd*. It may be uphill to get this included or at least linked to something else explaining it but I think it is a good idea. I also added myself to the bug as well. I saw the post on -doc. Dale Following Walt's recent thread about his experiences using grub2 I think getting folks used to disk labels at installation time, be they names or even better UUID's, might fit in very well with installation instructions that cover using grub2 instead of grub as a boot loader. - Mark

Lots of interesting ideas. I use apps so often I've never become very
strong at the command line and yet people built this whole Linux
empire using it. It's very powerful.
One thing I didn't make clear in my original post - it didn't seem
important to confuse my real question which was the copy itself and
not locating the files - but which likely changes how well some of
these commands would work in my specific case was that the Builder
directory actually has _many_ CSV files ut specifically I needed only
the ones in the Correlation directories. Additionally, being that this
is stock futures trading data, generally at a given time I need the
CSV files for a specific symbol, for instance in the original post:
c2stable ~ # locate Correlation | grep Builder | grep csv
/home/mark/Builder/TF/TF.D-17M-2009_06-2010_11/Correlation/TF.D-17M-2009_06-2010_11-V1.csv

/home/mark/Builder/TF/TF.D-31M-2009_06-2010_11/Correlation/TF.D-31M-2009_06-2010_11-V5.csv
c2stable ~ #
I knew I wanted the Correlation directory but it turned out I had
other directories with that name on the system, so I added the grep
Builder to get me into the right tree and CSV to find only the CSV
files. However at that point I only had Russell futures data (TF.D) so
I didn't have to go further. Now, however, as I bring in Dow futures
(YM, YM.D) , SP 500 futures (ES, ES.D), and NASDAQ futures (NQ, ND.D)
I just an an extra grep in and I'm there in terms of finding the files
I need for a certain test.
Additionally I have test results for other date ranges that will show
up soon, (2001-2005, or 2003-2011, etc. Additional greps are an easy
way to just winnow it down to a point where I'm finding what I need to
find.
This thread has given me a lot of new commands to go look at.

I started studying CUDA development recently too. While reading the
examples that come with the SDK, I found out that they're all C++ though.
The reason you can use C is that C is actually valid C++ (most of the
time.)
OK, I suspect I'm being limited by an include file which was supplied
with the exercises for the book CUDA By Design. Nice little book, easy
fun to read, good discussion of the basics for an entry level
programmer like me. Works fine if the file compiled is main.cu, but
fails if I rename that file main.cpp.
If I can figure out what is non-C++ in those files then I'll try to
focus on being C+ compatible because it seems all these IDE tools
expect that anyway.
I glazed over looking at the SDK examples myself because they are
frankly far beyond my programming skills without some text to
understand what they are trying to accomplish.
CUDA programming itself hasn't been all that hard. I'm luck that I
have a problem to solve that I think fits it pretty well.
That said, however, my understanding of what nvcc does is that what it
really does breaks apart the *.cu input files into portions that are

nvcc compiles into C++. The end result is then compiled with g++ and linked
with the CUDA libraries. This is normally done automatically by nvcc,
unless you use the --cuda option. For example, to suppress that automation,
you can compile a CUDA program with:
nvcc --cuda myprogram.cu
myprogram.cu can be something as simple as:
int main()
{ return 0; }
This will compile the program into myprogram.cu.cpp. This can then be
compiled manually with g++:
g++ myprogram.cu.cpp -L/opt/cuda/lib64/ -lcudart
It's just that nvcc does that automatically for you.
Really good info, thanks!
As for qt-creator, I tried the binary installer but after installing
it didn't run complaining that it cannot be mixed with the Qt
libraries that are on my system. I'll stick with the 1.3 version for
now and wait for portage to catch up.
Cheers,
Mark
P.S. - If you (or anyone else) wants to talk about CUDA, contact me

[gentoo-user] IDE recommendations for writing C?
Can someone recommend a good IDE to write C code in? 1) Something that can display multiple files in a project. 2) Something that have some sort of version control built into it? 3) If possible, I can compile right in the IDE. I've starting writing something. It's hundreds of lines long in 1 file and I just messed up a brace somewhere which I haven't been able to figure out in vi. Thanks, Mark

Emacs. If you dare to go this way. The learning curve is high, but once you know how to use it, you probably will be glad. Eclipse is pretty cool, and I've heard good things about Kdevelop. I've starting writing something. It's hundreds of lines long in 1 file and I just messed up a brace somewhere which I haven't been able to figure out in vi. Just use the % key. Wonko I specifically _don't_ want a high learning curve. I want this to remain fun, if possible. After an hour and a half of llooking for the problem in vi KDevelop with it's color editor helped me find the problem in a few minutes. That's a big help. I haven't figured out how to tell Kdevelop to use a different compiler but that's not important right now. I can build in a terminal until I learn how. Thanks for the ideas. I also loaded up codeblocks which I read good things about. CodeLite is supposed to be good but I couldn't get it unmasked. Netbeans wanted to install too much Java stuff. Understandable as it's written in Java but I decided not to look at that one right now. For now I'm set. Thanks! Cheers, Mark
[gentoo-user] [Slightly OT] Linking to a non-standard library installed using portage
Hi,
This is going to be trivial for anyone who actually programs.
Thanks in advance.
How do I link to a library I installed using portage? If someone
could show me an example make file that would be great. I've no real
experience in C and what I did have was in Windows years ago so I'm
undertaking some study here. I wrote a simple little test program that
calculates a simple moving average using ta-lib:
mark@c2stable ~/CODE/CUDA/Mark $ cat ta-lib-ma.cu
#include stdlib.h
#include ta-lib/ta_libc.h
#define VECTOR_LEN 100
int main(int argc, char **argv)
{
int i;
double MyData[VECTOR_LEN];
double MySMA[VECTOR_LEN];
TA_Integer outBeg;
TA_Integer outNbElement;
for (i = 0; i VECTOR_LEN; i++)
{
MyData[i] = (i*i)/(10*i);
}
TA_SMA(0, VECTOR_LEN-1, MyData, 10, outBeg, outNbElement, MySMA);
for ( i=0; i outNbElement; i++ ) printf(Bar %d = %f\n, outBeg+1,
MySMA[i]);
return 0;
}
mark@c2stable ~/CODE/CUDA/Mark $
The program compiles fine using NVidia CUDA compiler nvcc creating an
object file ta-lib-ma.o:
mark@c2stable ~/CODE/CUDA/Mark $ nvcc -c ta-lib-ma.cu
mark@c2stable ~/CODE/CUDA/Mark $ ls -al ta-lib-ma.*
-rw-r--r-- 1 mark users 477 Feb 3 10:08 ta-lib-ma.cu
-rw-r--r-- 1 mark users 17184 Feb 3 10:12 ta-lib-ma.o
mark@c2stable ~/CODE/CUDA/Mark $
However I cannot figure out how to link it to the ta-lib files
installed by portage:
mark@c2stable ~/CODE/CUDA/Mark $ equery files ta-lib
[ Searching for packages matching ta-lib... ]
* Contents of sci-libs/ta-lib-0.4.0:

/usr/lib64/libta_lib.so.0.0.0
mark@c2stable ~/CODE/CUDA/Mark $
What do I link to?
I've tried various things like this but none seem to find the library correctly:
mark@c2stable ~/CODE/CUDA/Mark $ nvcc -L/usr/lib64/libta_lib
ta-lib-ma.cu -o ta-lib-ma
/tmp/tmpxft_0a8b_-13_ta-lib-ma.o: In function `main':

collect2: ld returned 1 exit status

Thanks in advance for any pointers.
Cheers,
Mark

[gentoo-user] BUG: using smp_processor_id() in preemptible [00000000] code: X/4018
Hi, I haven't used the closed source ATI driver for long but I don't remember seeing this dmesg error before. It's not high priority for me as I'll be switching out the graphics card to an NVidia card hopefully tomorrow, but is this something that should get reported somewhere, or is it just the nature of the fglrx driver? Or maybe I've not configured the kernel as well as it could before this driver? Kernel is 2.6.36-gentoo-r6, ati-drivers-10.11. I did do a modules-rebuild -X rebuild and reboot to ensure it's repeatable. I suspect the LKML doesn't want this report as it's a closed source driver. Do the XFree guys want it? AMD maybe?

Yeah, probably too much work for the time I have available right now, and if I remove the HD 5770 in favor of the new NVidia card tomorrow afternoon then it won't happen until I try the card in some system at a future date.

[gentoo-user] Paste into vim keeping indention or original?
What is the solution to begin able to paste code I find on the web
into a file in vim and being able to keep the indentation from
changing?
For instance, here's the first few lines of code from a web page:
#define ARRAYSIZE(x) (sizeof(x)/sizeof(*(x)))
int main(void)
{
const char filename[] = file.csv;
/*
* Open the file.
*/
The indentation on the code from const down is consistently 3 spaces:
Pasted into vi:
#define ARRAYSIZE(x) (sizeof(x)/sizeof(*(x)))
int main(void)
{
const char filename[] = file.csv;
/*
* Open the file.
*/
In this case const is correct, but the next line is 6 spaces, then 9
spaces, then 12 spaces.
If it matters, I'm using KDE using Konsole, but I've seen this in
other WMs. I looked at the Tab settings in my Konsole profile but
nothing seems to matter.
Thanks,
Mark

I solved it by creating a .vimrc file and putting

Since no one else has given you the bad news, this is basically impossible if you care that the two programs behave the same. For any particular program, the best you can do is rewrite it by hand after creating a battery of unit tests. The alternative is to compile your source language to a common low-level language, and then decompile back to your target language.

The 'battery of tests' would be, I think, the trading program being executed on a certain market, producing a certainly list of buy sell operations and a specific gain or loss. It would be quite easy to compare the outcome because it's nothing more than a list of trades. If the translated code generates the same list then it works. If not, I dig into why. This part of the task seems relatively straight forward to me. I was mainly hoping to find a tool that might generate _reasonable_ C code, even if it's not perfect.

If you don't even have a common low-level language, what you're
essentially doing is creating a compiler for EasyLanguage. Take a small
example, adding two integers in E.L. I won't pretend to know the syntax,
but let's just assume that you have two integers (or numbers or
whatever) 'a' and 'b' declared.
How do you translate a+b to C code? You can declare two ints 'a' and
'b' in C, of course. But these are 32- or 64-bit integers. So if 'a' and
'b' are large, a+b will overflow. Do EasyLanguage integers work that
way? Probably not...
How about a/b? Does EasyLanguage do integer division, or does it treat
them like floats? If it does treat them like floats, do the rounding and
precision agree with C floats? Probably not, so floats are out too.
If you try to fix all of these problems, what you'll end up with is
something like a struct EasyLanguageInteger {...} with associated
functions add_easylanguage_integers, divide_easylanguage_integers, etc.
Then, you can translate a+b into add_easylanguage_integers(a, b) where
'a' and 'b' are now structs instead of just ints or floats.
Then, you'll have to write a parser that understands the rules of
precedence, looping constructs, functions, and everything else so that
they can be converted into the appropriate structs and function calls.
At the end, if it works, you'll have an EasyLanguage compiler.
Without a spec (the language is proprietary?), you'd have to guess at
most of that stuff anyway, so the chances you'd get it all right are
about zero.
Your best bet[1] is to create a ton of test data, and feed it to the
E.L. program. Make sure the test data triggers any edge cases. Then you
can attempt to rewrite the code in C, and compare the output. You as a
human who understands what the code does can take a lot of shortcuts
that a translator couldn't.
[1] I'm assuming you want to do this for a relatively small number of
programs, and that writing a compiler would not actually be less
time-consuming.
OK - this is probably WAY too off topic for this list. If folks
strongly want me to stop the thread I will but I appreciate the
technical adeptness of folks on this list quite a lot and the eventual
outcome would be the use of this thing on Gentoo, so I hope folks
won't mind too much if we continue a little further.
REALLY great points about the math issues. Thanks.
As for testing it _may_ be a slight bit easier than having to get to
that level. There is a library in portage called ta-lib which
implements lots of standard technical analysis constructs. After it's
installed I don't seem to have the C code for the actual functions
anymore. What I have is a compiled library as well as some header
files to look at. I suspect I can install the library again using
portage bt not getting rid of the functions which I could then use as
an example for my coding.
I have not used this library myself, but I've read enough on the web
to be reasonably sure it's results are very consistent with what
TradeStation functions of the same type do.
For a simple function call like a moving average EasyLanguage would write:
Inputs:
Price(Close),
Length(10)
;
variable:
MA1(0)
;
MA1 = Average(Price,Length);
Here is what I see for a similar moving average function from ta-lib:
/*
* TA_MA - Moving average
*
* Input = double
* Output = double
*
* Optional Parameters
* ---
* optInTimePeriod:(From 1 to 10)
*Number of period
*
* optInMAType:
*Type of Moving Average
*
*
*/

Use FEATURES=noclean and the patched source will be left under /var/tmp/portage. The unpatched source is probably in your /usr/portage/distfiles already. (I don't know if there *are* any patches for ta-lib, but if there are, you usually want them applied). Actually, the tar.gz file in distfiles was easily expanded and I found the code within for all the functions. I hadn't considered patches but fortunately there aren't any applied so it seems I get off lucky this time. SNIP If you can figure out what all those parameters mean -- that will be the hard part. What type of moving average is EasyLanguage doing? Which TA_MAType does it match up to? Can the E.L. version fail if it runs off the end of the prices array, or does it just add zeros at the end? Is there a way to make TA_MA do the same? Sorry I have nothing but discouragement to offer =) This isn't an easy problem. I don't consider this discouragement at all. In fact it's _very_ helpful. Documentation: I've found this much: Online at the following links: http://ta-lib.org/d_api/d_api.html http://ta-lib.org/function.html I haven't yet found a nice PDF that tells me the exact meaning of every parameter but I suspect it's out there somewhere. There's a forum for the library where people ask questions. I just noticed someone asking about writing documentation to be put in a Wiki so there's something going on. I'm not overly worried about matching up ta-lib functionality with what I use today in EL. Functionality: Software for real-time stock trading tends to be a little more restrictive than more general programming 1) First, we are operating on price data that has date time attached to every value. Think of a price chart for any stock. This stuff (in general) just operates across time in a forward direction. 2) When doing a moving average, for example, we are calculating from the current bar _backwards_. The only way to run off the end of the array is to try to reference too far back, so a 20 period moving average cannot be calculated before bar #20. As I go through a price data array, I just start at the length parameter into the array N[20] and keep going until the end. The way I see this is there's an upper layer that reads the price data in, puts it in an array and the calls the strategy bar-by-bar. (row-by-row in the array) When it gets to the last bar of data (last row with date and time) then it knows it's done. Pretty much all this stuff seems to work that way. At this point I feel like I've imposed on gentoo-user far too much. I was hoping maybe there was some program in portage for doing translations that might work but I guess there isn't. I'll let this thread drift asleep unless someone responds back. I think I've got enough info to sort of play around at this point, and I suspect my next set of questions are better addressed at someplace like StackOverflow as I can hardly program beyond Hello World at this point! ;-) Again, THANKS for your help and insights! Anyone interested in this subject matter is always welcome to contact me off-list. Cheers, Mark

[gentoo-user] [OT] - Code translation tools?
Hello, I'm wondering if there are any generic sorts of code translation tools in portage wherein I could translate from an 'uncommon' language no one here is likely to use (EasyLanguage) into C? As an example I've attached a little EL function that takes buy/sell command data an puts it away in an array for safe keeping. What tools are out there, if any, that might allow me to describe how EL works and then the tool does the conversion? Thanks, Mark Inputs: Array1[A1,AA1](NumericArrayRef), EType(StringSimple), EQty(NumericSimple), ESPrice(NumericSimple), ELPrice(NumericSimple), MyDate(NumericSimple), MyTime(NumericSimple) ; Switch (EType) Begin Case Buy: Value1 = 1; Case Sell:Value1 = 2; Case SellShort: Value1 = 3; Case BuyToCover: Value1 = 4; End ; If ((EQty = 1) and (ESPrice = 0) and (ELPrice = 0)) then //Implies Market order Begin Array1[Value1,1] = Value1-1; Array1[Value1,2] = EQty; Array1[Value1,7] = MyDate; Array1[Value1,8] = MyTime; End else if ((EQty = 1) and (ESPrice 0) and (ELPrice = 0)) then //Implies Stop order Begin Array1[Value1,1] = Value1-1; Array1[Value1,3] = EQty; Array1[Value1,4] = ESPrice; Array1[Value1,7] = MyDate; Array1[Value1,8] = MyTime; End else if ((EQty = 1) and (ESPrice = 0) and (ELPrice 0)) then //Implies Limit order Begin Array1[Value1,1] = Value1-1; Array1[Value1,5] = EQty; Array1[Value1,6] = ELPrice; Array1[Value1,7] = MyDate; Array1[Value1,8] = MyTime; End ; MWK.ADE_SaveSysTraderTrades3_ = 0;

Do you believe the results you get are meaningful? If you want another good experiment, remove -e and make the files much larger, like 2g if you have an 8GB or DRAM. Again, explain to yourself why this makes a difference. If you do this experiment you _really_ should just do the -i 0 test only your first time through... ;-) (HINT: You might want to open another terminal, run top and when in top hit iz and maybe m if you're not showing memory usage...)

Devices that have their driver compiled in do not have the line 'Kernel modules:' Devices that have neither line are controlled by the kernel but don't need anything from the driver section.
