Free NVidia drivers by Debian does *not* exists. There is only a package
which installs NVidia's drivers.

The easier and simpler, if you do not need good 3D acceleration is to
install nouveau instead of NVidia, which is a driver made from reverse
engineering.
In last kernels (around 3.8), it seems that there is also support for
better 3D acceleration, however I did not tried it since Debian at the
moment only have that kernel in experimental (and when I tried it, few
things broke. Did not investigate though).

Nouveau have the very good feature of not needing any Xorg.conf file: you
install it, you boot with it, it detects everything alone.

In short:
_ nouveau: free software, perfect integration in the system, average and
unfinished support (in linux 3.2 kernel) of 3D harware acceleration,
support all cards: both new and old(nouveau-vieu is what you would want).
_ NVidia: proprietary software, bad integration in the system, support for
advanced 3D features, no support for old cards.

 2.  How do I determine the current color depth (e.g. 8/16/24 bits per
 pixel)?

IIRC:
xrandr --output port you used: VGA, HMDI, etc --list

 3.  How do I change the display settings -- resolution, refresh, color
 depth?

xrandr --output port you used --mode your parameters

Play with xrandr in a terminal emulator, and when you have what you want,
add the command to your DE's startup list (depends on your DEs)

It is not still not working like a charm, since I tried kernel 3.8 to try
a game (regnum online, bugged as hell, but at least it have a linux client
which is playable) which perfectly works with official NVidia. The result
with nouveau of 3.8 was only a black screen (for 3.2 the game simply said
that some features were lacking and closed).

Another problem I know by following linuxfr, is that automatic adjustment
of fan speed according to temperature is not functional. At least,
according to a guy who claimed to be a contributor of nouveau :) (I did
not checked his assertions, I have other things to do than mistrust people
which give fairly good technical explanations and are recognized by more
ancient people of the community than me)

There is still a lack of support for dual card configuration (I have such
configuration, but I do not use it anyway: my two cards are just cheap
ones and the second were bought after an error of mine about which
component of my computer was out of order...) and IIRC card switching that
we can find in some portable computers.

Of course, those features which are lacking are only for special cases,
and for all other stuff, nouveau is really good, my intent is not to deny
that fact, and I am waiting impatiently to see the 3.8 kernel in debian
testing, to get rid of that piece of crap named nvidia drivers, which only
give me problems and the ability to play one or two games I could not
otherwise play (nexuiz is still unplayable with nouveau 3.2 too, but it's
engine really became a PITA in performance point of view).

Wesnoth, unvanquished, openmw and so many other which have a free engine
works like a charm (on the graphic point of view, since I have real
problems with unvanquished, which I should try to solve, one day, because
this game is a really good -and different than average FPS- one).

Anyway, nouveau have always (since I know it, so, not so many time, maybe
2 years :D) be the best when you have no need for 3D features.
And now, 3D features are coming, so, I will profit from that message to
say Good job, guys, and thanks you a lot! to it's developers.

Re: debian-6.0.7-amd64 how to set resolution and refresh for free NVIDIA X drivers?

Yes, AFAIK all your claims a correct! I needed the nv driver for a long
time, because nouveau completely didn't work, today it can be possible
(but it also still can be impossible) to use 3D and even to use the
driver for real-time applications, even for cards that completely didn't
work in the past. It's much better than it was a long time ago.

At the moment I use my ATI, it seems to be less good supported than my
NVIDIA. I switch the cards from time to time, regarding to unusual
needs, in my case it's audio real-time.

I still use xorg.conf, but it could be that xrandr does work as good as
the xorg.conf does work.

wheezy still missing php5-suhosin

2013-04-10 Thread Andrew McGlashan

Hi,

I'm working on a server replacement, the old (current) server is running
latest stable release and the new server is running from this downloaded
installer ISO:

   debian-wheezy-DI-rc1-amd64-netinst.iso


Now, php5-suhosin provides some real protection against programming
problems that could very easily exist and it is not uncommon to see
messages from Debian stable installs reporting bugs / vulnerabilities
detected by suhosin

It seems to me that this is an essential package for most servers
running PHP5 and it's non-availability is a very serious concern.


I've found the following:

http://packages.qa.debian.org/p/php-suhosin/news/20120320T163911Z.html


Will php5-suhosin be re-instated any time soon?  And if not, what
measures can we take to protect Wheezy servers now?


Thanks
AndrewM

Forgive me if I'm not using the proper terminology or not explaining
this properly. This aspect of running a small business is foreign to me.

My wife and I run a small independent coffee shop and I'm the geek in
charge. I've got m0n0wall running great with the customer wifi on DMZ and
all our machines on a private LAN. We've got a recycled Pentium 4 running
Debian stable for our Music Player Daemon server. Motherboard is a Tyan
with real serial ports.

We have a mid-line Casio cash register setup that has 2 serial ports. 1
is dedicated to the credit card machine. The other can be connected to a
serial pole display. I understand that this second serial port outputs
formatted text of all buttons pressed and transactions processed.

This is also useful for overlaying this text with a CCTV camera connected
to a DVR. Though, this setup limits how you can search for mistakes or theft,
having to sift through hours of video.

I'd like to do the following with Debian: Use the text from the serial
port in conjunction with an IP network camera connected to our server. I'd
like to be able to search the text for particular triggers, e.g., look at
video whenever someone hits the NS (no sale) key to open the drawer.

I think I can connect the Casio to one of the serial ports on the server and
capture data through tty(?).

The text would not necessarily need to be overlayed but must sync with the 
video.
The Casio has a pretty accurate clock, running on 60Hz; the IP camera can
sync via NTP on our m0n0wall router.

I've Googled a few commercial solutions but they are very expensive and
are proprietary. One is this:
http://www.geovision.com.tw/english/Prod_GVDataV3E.asp

I'm thinking something like this must have been done with Linux for other
fields, e.g., scientific sensors outputting text on a live stream.

Any ideas or suggestions?

 Timemachine is the program:

 The idea is that you doodle away with whatever is kicking around in your

Integrating the two and searching based on triggers or text would be the key.

Maybe you can reuse the old package.
Check the dependencies, it is possible that there has been no changes in
them.
If there has been, take a look to applications' changelogs, to see if the
new versions are compatible with the existing dependencies.

As you might know, there is a more or less standard versioning scheme
named semantic versioning (it is quite easy to understand even for a
non-native english user like me. You can find it's description here:
http://semver.org/). If dependencies uses it, you will be able to check
compatibility quite quickly: if major number did not changed, then you are
fine.
Of course, since you are willing to use this tool on a production server,
I strongly encourage you to take a look into changelogs and/or ask to
their developers to ensure nothing should be broken.

Re: sync apt/dpkg state between systems?

2013-04-10 Thread Thilo Six

Hello Bob,


Excerpt from Bob Proulx:

-- snip --
 Let me tell you why i suggested etckeeper.
 Here i use it to commit /etc into $VCS on a regularly basis. This helps me to
 keep track of what is going on in /etc.
 Being able to compare my modifications with the original is a feature you 
 surely
 will not miss anymore, after you get used to it.
 
 This is where our strategy of attack on the problem is different.  I
 started from the idea that there are a lot of files in /etc but only a
 few of them need to be excluded from the restoration.  Therefore
 identify the files that should be excluded.  Then restore everything
 *except* for the files that should be excluded.  Whereas I think you
 were started from the idea that there a lot of files in /etc and only
 the known okay files to restore should be restored.  Identify the
 files that should be restored and only restore those files.
 
 Basically one strategy is include all but those excluded and the other
 strategy is exclude all but those included.
 
 I think we are in agreement that some files must be restored and some
 files must be excluded.  We differ on the technique to get there.

Excellent summary!
It is like positiv vs. negativ logic in bollean algebra. If you know the rules
with both you can reach your goal, just the way in between is different.


-- snip --
 Dpkg::Options {
 --force-confdef;
 --force-confold;
 --force-confmiss;
 }
 credits for this go to: http://raphaelhertzog.com
 
 That controls the behavior of dpkg when it would normally stop and
 interact with the user admin who is installing or upgrading a package
 about the handling of a conffile.  Should you install the new package
 file, keep the existing file, or merge them?  Or see the differences
 between them?  The above answers those questions globally so that it
 never stops to ask a question.
 
 I fully agree with confmiss.  I routinely set that too.  But I have
 seen heated arguments from people who have argued (apparently
 successfully because the change went in) that removing a required /etc
 file is a desired configuration and that it must be preserved.
 (Regarding the /etc/network/interfaces file.)  This adds yet another
 logical state to be considered.
 
 I use a system configuration management system similar to cfengine,
 puppet, chef that I have programmed to configure the system.  I have
 directed it to read-modify-write various configuration files to set
 them as desired.  In that type of environment it is advantageous to me
 to use confnew.  With confnew I will always get the package version of
 the file with the package default configuration.  Which will then
 immediately be reconfigured into my desired configuration by the
 system management tool.

I understand we do have a common understanding of handling such things.
As i do not have to administer a bulk of systems i differ in that i do not have
the need for an advanced configuration system as cfengine.
But apart from that my workflow to handle /etc is similar to yours.
With 'confold' dpkg by default keeps the configuration that is already in place
in production and installs new configurations from DMs as foo.dpkg-dist.
My VCS then notifies me about new or changed files and the i go through them and
merge them as i see fit.



-- snip --
   * Exclude /etc/fstab
   * Exclude /etc/lvm
   * Exclude /etc/mdadm

 + /etc/initramfs-tools/conf.d/resume
 
 Ha!  I always use lvm and so for me the names in the
 /etc/initramfs-tools/conf.d/resume file are always logical names and
 would be the same across systems.  But point taken.  If that is a UUID
 then it should be excluded from the restore.

here on my system it does:

$ grep -o 'RESUME=UUID=..' /etc/initramfs-tools/conf.d/resume
RESUME=UUID=7bb317c1-e


 Plus there is your note about ethernet addresses.  In addition to the
 70-persistent-net.rules file that may also affect people using
 guessnet or other such networking packages.
 
 ..and maybe some more. This is why i would look into the difference prior to
 rsyncing. After i had become confident i would use rsync, too.
 
 At the center between the strategies of include and exclude is the
 need to identify which files must be included in the restoration and
 which files must be excluded.  Having that list then we would restore
 what should be included and avoid those that should be excluded.
 
 I think you and I would both identify these files on-the-fly by seeing
 the files, by looking at the file contents, by other dynamic decision
 making.  But I fear that for many people that would be beyond their
 level of skill.  Our discussion shows that it isn't trivial.  It takes
 some experience.
 
 Can we document what we have learned from this discussion?  Would
 someone be able to follow that documentation and successfully peform a
 restoration as described?  Is it possible to create a script that
 would analyze the backup and the new system and would then identify
 the files that should be included and

The main interest of xrandr in my opinion is, that it is far easier to
play with than what I can easily name the ugly Xorg.conf.
Here are some examples:
_ user can configure his screen himself, no need to sudo or su
_ no need to restart anything, it's dynamic. You can
add/move/remove/resize screens without any problem at your will.
_ far easier to learn for a beginner: it took less than 10 minutes, while
Xorg.conf will require hours of web browsing. And web browsing without a
good resolution is a pain in...
_ if your multiple screens have different resolutions, there is no ghost
space, so you can not loose your mouse cursor.
_ it have nice GUI interfaces (I do not use them, but I think it is a
power to have some) like lxrandr. So if you want a normal user to use it,
he will not need to learn anything :)

Considering that my 2 computers are some of the cheapest I know about (an
eeepc laptop and a desktop repaired multiple times with 2 different
screens, and one which will blow it's 10th candle this year, with its
1024x768 max resolution :D) this power of the randr extension is really
comfortable.

And nouveau supports all of this out of the box since at least 2 years,
unlike NVidia.

I think you should take a look at this
http://nouveau.freedesktop.org/wiki/FeatureMatrix if you want to have a
good viewing of were it is for your GPU.

Just one question: what is the link between audio stuff and graphic card?

Re: Pioneer BDR-206 Internal Blu-Ray Disc DVD/CD writer and Debian

2013-04-10 Thread Thomas Schmitt

Hi,

 According to this[1] bug (found by searching the internet for Merging data
 is impossible with this disc), brasero doesn't support BluRay discs.
 [1]https://bugs.launchpad.net/ubuntu/+source/brasero/+bug/637379

Well, that bug seems somewhat outdated.
But of course, Debian packages are outdated too.
Maybe this bug is even too young for Brasero 2.30 as is
packaged in Debian 6.

Current Brasero source from git seems to have clue of BD media.

Other than xfburn, where BD media might work nevertheless,
because i cannot spot code for their rejection and because
libburn supports them in version 0.8.0 of Debian 6.


So there remains xorriso command line. Like

  xorriso -outdev /dev/sr0 -map ./my_disk_file /my_iso_file

which puts the file ./my_disk_file as /my_iso_file into a
ISO 9660 + Rock Ridge filesystem on the blank medium in /dev/sr0.
The BD-R medium will stay appendable, i.e. more files can be
added in further sessions until the medium is full.
For adding another session:

  xorriso -dev /dev/sr0 -map ./some_disk_directory /some_iso_directory

Good for about 300 sessions on the same BD-R. More than
one -map command can be used in one run to add multiple files
or directories. (Actually there are lots of commands available.)

This should work even with the frightening old xorriso-0.5.6 as
packaged for Debian 6.


After unfreezing of Debian, i hope for xorriso-tcltk to appear in
testing. It is half way between GUI and command line :))
  http://www.gnu.org/software/xorriso/xorriso-tcltk-screen.gif


Have a nice day :)

One claim is, that shared memory could cause issues. I own a card with  
it's own memory and currently I use an onboard device, that does share RAM

never caused issues for me.


Sometimes when getting xruns (audio glitches), they can go away when using  
another graphics or graphics driver.


Using proprietary drivers sometimes doesn't work with real-time patched  
kernels, regarding to licensing issues. There are workarounds to ignore  
the license, that often do not work. Instead of using a real-time kernl,  
it's possible to use a full preempted kernel and as boot option using  
threadirqs, however, a real-time patched kernel still could be a little  
bit better than a full preempted and since the hardware registers aren't  
accessible directly by PCs, as it is possible for the C64, Atari ST, PC  
anyway don't have that good real-time abilities, so IMO it's better to use  
a rt-patched kernel.


Last but not least, as for all hardware, the graphics could share the IRQ  
with the sound device, fortunately modern kernels seem to ensure that the  
graphics get it's own IRQ.


On my machine 2 USB ports, the graphics and my sound card share IRQ 18.  
With modern kernels, the graphics gets another IRQ and I wrote a script to  
unbind the USB ports.

RAID 6 mdadm

2013-04-10 Thread Muhammad Yousuf Khan

i was watch a person's video regarding RAID 6 with mdadm
his configuration was very low, some old system probably
2GB RAM, 3x8TB Hard Drives, 4port Ethernet card for channeling.
and the guy was giving review of his home server. he says he will channel
the 4 port Ethernet to achive 4Gbps network throughput. and 2 drive
redundancy with RAID6.

my question is
since i can not invest that huge money for testing so just asking from

That's an odd setup. Why use RAID6 with only 3 drives? He'd get better 
performance with RAID1 with only 3 drives.


However, your question is about performance. My RAID5 array with SATA 2 
drives gets about 200MBps. SATA 3 performance should be double that.


Caching is critical. Disk access is dramatically slower than memory 
access so that your real throughput will depend on how much disk access 
can be avoided or optimized.

Re: debian-6.0.7-amd64 how to set resolution and refresh for free NVIDIA X drivers?

David,

Since you are willing and able to reinstall from scratch, it may be worth
trying the next release of Debian, currently considered 'testing', known
as 'wheezy'. You can get wheezy Release Candidate 1 release installation
media from here:

http://www.debian.org/devel/debian-installer/

Wheezy is to be released imminently, so it should not be significantly more
unstable to use than you would expect from a stable release. However it is
much newer than squeeze, and the open source nouveau driver has been under
rapid development, so the version in wheezy is likely to have a much larger
set of supported cards, and many bugs squashed compared to squeeze.

Once you've done that, if you could try attaching a Xorg.0.log that results
in running X *without an xorg.conf*, that may be useful too.

Cheers

 From my current Ubuntu:

OP beware, please do not try something like Ralf's xorg.conf yourself.
For a start, it specifies the radeon driver; but it also declares modelines
that may not be appropriate to your monitor, which in extreme cases could
result in hardware damage, apparently.

Modern X should not require any xorg.conf at all, with all relevant information
automatically detected, and the goal here should be to get you to a desired

A home directory on removeable storage ...

2013-04-10 Thread peasthope

... is possible.  I understand the concept of mounting 
the filesystem.  

Additionally there can be a backup home directory which 
stays with the machine, on a hdd for example.  I imagine 
that when the machine powers up without the removeable 
storage, the backup home directory is instated.  When 
the removeable storage is connected, the backup is 
remounted as another directory in /home and the removeable 
is mounted as the home.  

So for example, without the removeable present /home/peter 
is on the hdd.  With the removeable present, /home/peter 
is on that and the hdd is /home/peter.bak with the same 
ownership and privilages as /home/peter.  With udev, it 
might be accomplished with one or two scripts.

This can't be an original idea.  Is it available?

Is pam_mount of any use to you? It's intended for mounting home

I'm not sure how you'd access the original /home/peter once you'd

You cannot get more than about 200MB/s out of a RAID1 setup, not even with 
15krpm SAS drives. the RAID1 will never be faster than a single disk. How 
would it.

If you want to saturate 4G*bit* ethernet (gigaBIT! not byte!) which comes down 
to 500MB/s raw across all interfaces, so 125MB/s on one nic you definetly do 
*not* want linux softraid 6. either patch up the kernel with ZFS or if you 
wanna cross the t's and dot the i's: get a HP Proliant N40L, put a 
KVR1333D3E9SK2/16G 2x8GB ECC mem kit in it, install FreeNAS, add 4 7k2 rpm 
drives of your choice and create a z-raid over it, you should see 400MB/s.
Has 2 slots, on pcie16x, one 1x so should take a 4xGBE card and there you go.
Due to the massive caching and whatnot zraid uses and hence the amount of data 
in the 16GB make sure it's UPS backed. So far we're looking at roundabout 450 
USD without disks and UPS, but you'll have one heck of a NAS.

Now, *this* totally is not debian anymore, so back on topic:

I have a 5x1500GB raid5 from 72krpm sata drives and without optimizations, 
LVM2 and xfs on top of it get about 80MB/s write speed. raid6 probably would 
slow to a crawl (platform is a core i5 quad @2.3GHz)

If you mount a new filesystem onto an mount point of an already mounted 
filesystem, processes which have their current working directory within the 
mount point will not recognize the change. The Linux kernel doesn´t take the 
original filesystem away from these processes unless the change their 
directory to outside of the mount point and then inside of it again.

 It's my first time meet this issue.
 
 So I wonder which may lead to this episode?
 

Without data, we can only speculate. Here's my wild speculation:

You thought you had multiple terminals open, but what you had
was a single master process with multiple sub-processes. A
failure of some kind happened in the master process and when it
died, it took all the children with it.

 I'm not sure how you'd access the original /home/peter once you'd
 mounted the removable home on top of it, ...

The removeable shouldn't be mounted over the non-removeable. 
First unmount the non-removeable and mount it on /home/peter1, 
for example.  Then mount the removeable on /home/peter.

 Is pam_mount of any use to you? It's intended for mounting home
 directories on login.

The remount-followed-by-mount should be independent of login.  
Similarly, if the removeable storage is removed, then the 
non-removeable filesystem should be moved back to /home/peter, 
for example.  Anything for mounting specifically at login does not 
appear to be appropriate.  I imagine a script invoked by udev where 
insertion of storage triggers remount-followed-by-mount and 
removal triggers the remount.  

Thanks,  ... Peter E.

Re: wheezy still missing php5-suhosin

 Now, php5-suhosin provides some real protection against programming

 The question isn't whether the suhosin patch did good with older PHP
 versions.  The question is whether newer PHP versions benefit as much
 from it.  Because in recent years AIUI many of the features of suhosin
 were merged into the mainline PHP.  And supporting suhosin isn't easy.
 At least some other distros have also stopped supporting it too.

I understand that Ubuntu have 12.10 locked in on 5.3.9 because of lack
of Suhosin patch / support.  Don't know what later Ubuntu will be doing.

 Will php5-suhosin be re-instated any time soon?  And if not, what
 measures can we take to protect Wheezy servers now?
 
 Here is a good place to read up on the current state of PHP plus
 suhosin in Debian.

 It is a long thread with a lot of references to research.  Grab a
 comfortable chair and a stimulating beverage.

Great, thank you very much for your post and the reference.

To cut a long story short, if PHP upstream has incorporated the features
of Suhosin, then we should be fine; is it the final conclusion from that
long thread and all the references from it, that we are in good shape
with 5.4.4 -- better than pre 5.4 with Suhosin?

To be honest I have not read through all of that information myself
yet in enough detail to know one way or the other.  It really needs
the skills of an upstream interpreter developer to know.  I would love
to hear from someone who is familiar with the code well enough to make
an intelligent summary.

What I have read (caution unverified) is that the PHP interpreter
isn't intrinsically insecure.  It only becomes that way when used with
insecure php code.  Which makes sense.  Any upstream interpreter
vulnerability would have a CVE number associated with it that would be
tracked.  I see people calling for those reports but none are being
provided for any current vulnerabilities.

You cannot get more than about 200MB/s out of a RAID1 setup, not even
with
15krpm SAS drives. the RAID1 will never be faster than a single disk.
How
would it.

It can read faster than a single disk by combining reads from different
sectors on different disks.  I think your assertion is incorrect for
reading, though  not for writing.

Ross Boylan
Exactly. Most data is read more often than it is written so that read 
performance is critical.


In the particular setup of RAID6 with only 3 drives, each drive gets the 
same amount of information as they would in RAID1 so that write 
performance also does not change. However RAID1 requires less CPU time 
and is arguably more reliable (please let's not start a debate on this - 
it's not a big issue).


The advantage of RAID6 comes when you have 4 or more disks. Because each 
disk then gets only part of the data, write performance can improve.

Uhm...  Are you sure you were looking at info pages?  AFAIK the
dpkg-dev package which includes dpkg-scanpackages does not provide any
info pages.  It only provides man pages.  I think you must have been
looking at the man page in the info viewer which falls back to man

I think this entire subthread talking about info pages is a red

I remember there was a (commercial, MS Windows) Russian OCR software 
some years ago, really good working then; probably it could handle 
handwriting to some extent:

I never used it for handwritten text though.
Another option is to hire some teenagers or students who'd like to earn 
some additional money if you have funds for that - both ways need 
proof-reading afterwards.


Not sure which database would be good for storing images; is MySQL 
capable of managing it in an efficient way; perhaps Postgress SQL or 
another solution is better. You could also store the images on the drive 
and keep links (paths) to the images in the database.


Did you try contacting other institutions which might have similar needs

 actually what i need is 4GB LAN throughput with teaming (802.3ad) for data
 storage to backup VMs and same huge data manipulations will be done. so
 just confused if it going to work or not.

Addressing the bonded ethernet issue:

802.3ad LACP configured at the switch and within the Linux bonding
driver will facilitate TRANSMIT TCP stream load balancing.  However, it
does nothing to address RECEIVE load balancing.  Your application is a
~100% receive workload.  So LACP is out.  Linux balance-alb is required
to achieve any level of receive load balancing.  It does not require
bonding support in the switch.  And it only works with IPv4.

See:  https://www.kernel.org/doc/Documentation/networking/bonding.txt


Addressing the storage issue:

RAID6 only has good write performance in a single scenario: large single
streaming writes, such as video recording, large file backup, etc.  If
your writes are smaller than stripe width you incur read-modify-write
cycles.  These can triple (or more) the number of heads seeks per drive
required to complete the write, and you suffer the extra rotational
latency in between the seeks.  Thus if you're performing multiple
partial stripe width writes in parallel, then your performance, even
with expensive hardware, will drop into the teens of MB/s.  And if
you're doing multiple streams RAID6 isn't suitable simply due to the
extra head seek and rotational latency of double rotating parity writes.

So if you're serious about achieving an aggregate 400MB/s of write
throughput to the array, with this workload, you're very likely not
going to get there with 8x 7.2K SATA drives in RAID6.  Depending on how
many concurrent backup streams you're running, and what filesystem
you're using, you might get close to 400MB/s using 10 drives in RAID10.
 The more concurrent jobs, the more spindles you need to mitigate the
extra seeks.  This will also greatly depend on your backup job write
pattern, and thus the chunk/stripe width you select for the array.  The
RAID parameters must match the application write pattern or performance
may be horrible.

And lastly, select the right filesystem for the job.  EXT3/4 are not
suitable for large parallel streaming writes.  You will likely need XFS
for this workload for optimal performance, and you'll need to align the
filesystem to the md/RAID stripe parameters during mkfs.  If you're
directly formatting the md/RAID device, mkfs.xfs will query the kernel
and configure proper alignment automatically.  If you use LVM between
md/RAID and XFS then you'll need to do manual alignment during mkfs.xfs.

Parting thought:  It's very easy to get 400MB/s write throughput from an
8 SATA drive md/RAID6 array when doing single streaming writes from 'dd'
or other simple one dimensional tests.  However, achieving 400MB/s with
real workloads is a completely different matter and much more demanding.
 Most of the md/RAID throughput data you'll find via Google comes from
these one dimensional simplistic tests.  Don't trust this information.
Look for specific workload tests or synthetic benchmark data from
bonnie, iozone, etc.  While these won't precisely mimic your workload,
they give a much better picture of potential real world performance.
And the numbers will always be much, much smaller than 'dd' numbers.

 Then dm would have to manage/combine the reads from the involved disks.
 I do not know better, but I doubt this is done. 
 I'll ask the raid list for curiousity's sake.

It's not necessary to ask on linux-raid, and as you have not yet done
so, I'll clarify this now:

Both the md RAID1 and RAID10 personalities will read sectors in parallel
from both disks in a mirror pair in most circumstances.  This has been
the case for many years.  This is a read optimization only.  Writes
occur in parallel as well, obviously, but as it's the same data the net
data throughput isn't doubled, only the raw device throughput.  This
should be obvious to anyone.  I'm merely being complete in my description.

You have a monitor which can do 1600x1200 but xorg can only see fit
to give you 1024x768. This may be because the monitor is not
providing suitable information to xorg, so it serves up 1024x768 so
as not to disappoint you. Look at the Xorg log in /var/log and search
in particular for 'EDID'. Is there anything like that or references
to monitor resolution there?

 My xrandr apparently has no --output X --list option:

First test the display resolution you want to have as described by

yours:

I used 'cvt 1280 1024' to get the Modeline.

Since the issuance of the Accounting and Auditing Report on the Observance of 
Standards and Codes in 2005, Indonesia has made significant efforts to improve 
the quality of corporate financial reporting. Considerable progress has been 
made to strengthen the institutional framework of accounting and auditing and 
to move toward convergence with International Financial Reporting Standards 
(IFRS) and adoption of International Standards of Auditing (ISA). Investors and 
companies with operations in Indonesia need to be aware of these standards as 
they may have major effects on their financial statements and structures.

This one-day seminar led by Saptoto Agustomo, Partner from RSM AAJ Associates 
Indonesia will provide participants with essential knowledge about the 
IFRS-based Indonesian Financial Reporting Standards and its implications on 
their businesses.
 
Highlights:
- Learn about the recent developments in the Indonesian Financial Accounting 
Standards framework
- Understand the key differences between IFAS and IFRS
- Discover the tax implications and other issues that may arise from the IFAS
- Pose questions to the expert from Indonesia and network with other 
professionals

Registration Fees: 
Regular fee - RM1,200.00 
Early bird fee - RM1,100.00 (for registrations received by 12 April 2013)
All fees include lunch, documentation and refreshments

Yes, but insecure code is so easy to make and even the so called experts

properly patched servers shouldn't be part of the problem.  PHP needs

that is what Suhosin aims to achieve.  Bad code will be there, we need

Starting Iceweasel

Dear list -

Thanks for all your help.

Finally, I can start Iceweasel from the command line [sort of]: 
iceweasel -no-remote localhost/choice.php width $1280 height $800


The above works.

But ... in a store.desktop multiple windows are opened.

FYI Iceweasel is NOT running when I issue the command or click on the icon.

PS
The suggestions on migrating icedove to Thunderbird look excellent.

I'm reasonably good at three things at one time, but six is a little 
much.  As soon as I can climb out of the hole I am in, I'll do the 
migration and give a detailed answer.
