You can find per-topic dictionaries from the מאגר המונחים of the Hebrew
Academy at the link below:
https://terms.hebrew-academy.org.il/Millonim
Most computers related dictionaries are marked with "טכנולוגיית המידע".
Or you can just search for English terms translation at

Given the nature of CGI you can write CGI programs in any language you like,
as long as it can write text to standard output file descriptor.

No, as long as you are an authenticated user it should pass whetever

it won't be your official smtp server, but you may be able to set
policies that declare that it is a trusted origin server. (
You can for instance also send you @gmail mail through a smarthost,
but it will result in a warning showing in gmail that the mail may
not be from the person since the mail came from a non-google smtp
server. Also note that the smart host will most likely not use TLS for
communication between smtp servers (it may use it for yousmarthost,
depending on how good your ISP is), but you would anyhow only be able
to do that if you are willing to shell out the required money to get
a signed certificate (self signed is nice for testing but 3rd parties
will never accept them [as they should]).
I have my certificate signed by CACert, but if that doesn't look like
enough then I'll probably decide if it's worth it based on the price.
CAcert's certificate are not generally trusted (see
http://lwn.net/Articles/590879/). A free alternative is StartCom's StartSSL.

According to Documentation/PCI/pci-iov-howto.txt newer SR-IOV supporting

I don't see support for either in mainline U-Boot. Barebox supports ubiformat

Your best option is to boot into RAM using a kernel combined with a minimal
Busybox based initramfs, and extract you tar from there. Note tough that
Busybox tar does not support extended attributes, so you must use GNU tar for
this. Buildroot can generate a minimal initramfs image for you quite easily.

I met of late, problems with using, with Hebrew texts, some latex

The first one was some time ago, when trying to make the text flow
around an image (plain Latex). It warked smoothly with English text but
issued an error message when the same commands were used with Hebrew text.
I do not recall the exact error message.
Lately, I tried to superpose text on a semitransparent image, using the
eso-pic and transparent packages (pdflatex): Worked smoothly with English
text, but with Hebrew I got the following error message:
pdfTeX warning: pdflatex: \pdfrestore: missing \pdfsave
!pdfTeX error: pdflatex: 1 unmatched \pdfsave after page shipout
== Fatal error occurred, no output PDF file produced!
shell returned 70
In an attempt to understand what is going on, I tried to define English as
the first language and put in some English text, before the Hebrew one. It
worked allright, as long there was enough English text to cover the first
page, on which the image appears, but balked, when this was too short.
One can, of course, achieve the desired result, by combining two pdfs,
but I would like to understand the problem -any references are welcome-. I
would also like to know if there is any workaround within latex.
Are there any good text or other references about latex in Hebrew?
Have you tried using xetex (xelatex)? I wasn't able to get working Hebrew from
ptflatex. xelatex works quite well for me.

I'm not looking to bypass power/frequency limitations, just to send

A Linux WiFi driver is meant to give you access to a network, not to let you
control the radio signal used to send network packets. Even if a WiFi hardware
that allows tweaking the radio signals did exist, I doubt a standard driver
would expose these capabilities to the user.
You may, however, have some luck with this:
https://github.com/qca/open-ath9k-htc-firmware. This is the source code of the
firmware running inside the WiFi hardware of some Atheros (now Qualcomm)
products. You'll have to tweak the firmware code to expose the desired
capabilities to the host machine. Then, you need to teach the kernel driver
(ath9k) how to use these capabilities.
I hope this helps.

I really don't think so. SSDs (IMHO) makes computer much faster due to the

data, instead of... reading it :)
Absolutely correct. However, there is a tiny fraction of the seek time
that is not always a waste, and I think it is worth mentioning. There
is, I believe, a consideration that is usually overlooked when SSDs
are considered for server use, including a desktop that is used as a
server, which is why I am mentioning it here. In a server, magnetic
disk rotation - or, rather the air turbulence generated between the
rotating disk and its enclosure - is the only source of entropy that
makes random numbers random (seek times have a tiny random component
due to the turbulence, and it is captured). This does not apply to
SSDs, and as a result your security may be compromised (attacks
exploiting not very random RNGs are well known).
Recent Intel CPUs introduced the RDRAND instruction that is essentially a
Random Number Generator. Recent kernels (v3.2 and later) added support for
this instruction. See http://git.kernel.org/linus/628c6246d4. See also the
related commit (from v3.6) at http://git.kernel.org/linus/c2557a303 (and note
the funny commit log).
These patches were backported to all supported stable kernel trees (back to
v2.6.32).
In a laptop or a desktop entropy is also generated by keyboard and
mouse (which may or may not be good enough). In a server that hardly
applies.

There is no mention of which driver it needs, and I strongly suspect
that the 1000 Mbit part requires nonconventional drivers as was the
case with Asus board's NIC. There wasn't even a legacy mode for 10
Mbit communications.
See the list of currently (as of version 3.8-rc1) supported PCI IDs of Atheros
GbE Ethernet devices in drivers/net/ethernet/atheros/atl1e/atl1e_main.c,
drivers/net/ethernet/atheros/atl1c/atl1c_hw.h and
drivers/net/ethernet/atheros/atlx/atl1.c. You'll need to access a running

You are right. This driver has not found its way to the mainline kernel yet.
Its homepage is at
http://www.linuxfoundation.org/collaborate/workgroups/networking/alx, and
although it has been posted for mainline inclusion back in August
(https://patchwork.kernel.org/patch/1376841/) the authors have not followed
up. It is somewhat strange that this driver has found a (temporary) home in
the compat-wireless package (https://lkml.org/lkml/2012/10/8/409), which is
where you installed it from. Maybe it is so because the compat-wireless
maintainer, Luis R. Rodriguez, is an Atheros/Qualcomm employee.

As far as I know the state letters come from the third field in the

Re: Possible Solution for Frequent Keyboard Hangups in KDE.
Hi Nadav,

On Fri, Sep 14, 2012, Shlomi Fish wrote about Possible Solution for Frequent
Keyboard Hangups in KDE.:
Hi all,
in case you are experiencing cases where the keyboard in KDE become
unresponsive sometimes, then I have discovered a way to predictably
reproduce this hang-up, and to avoid it. See this KDE bug here:
Sadly, this is a much bigger problem than you describe, which has
plagued various distributions for the last year: People have been reporting -
and it also repeatedly happened to me personally - that X Windows's
keyboard hangs while the rest of the computer (as well as the mouse)
continues to work normally. To some people, this hang happened several
times a week, bringing Linux's reliability close to that of 1990s MS
Windows :(
Further investigation revealed that the keyboard is NOT actually hung,
but rather in a little-known state called SlowKeys - if you press a
key for over a second, it *will* be accepted. If you care enough, you can
actually type something in this weird state. But clearly this state was
meant for people with very specific disabilities - and not for the
general population. So how and why is does one randomly get into this
state?
Continuing the investigation, you'll discover that when X is in a new
and little-known state called AccessX, it enables the dreaded
SlowKeys mode when you press the shift key for 10 seconds. Yes, that's
right - if you daydream with your hand on the shift, bye bye keyboard.
I just wanted to note that for me, at least, another 10 seconds Shift key
press toggles the keyboard to its normal non-SlowKeys state.
So, you might be asking, why is this AccessX state even turned on by
default? Apparently, it *shouldn't*. X does *not* turn it on by default.
But various buggy Gnome and KDE crap do. On my Fedora, it is GDM (the Gnome
login screen - which is used even if you end up running KDE) which turns it
on (apparently to help people with disabilities to log in) but forgets to
turn it back off when it starts the session. Various window managers also
turn this feature on - it should be off by default unless the user chooses
this feature, but apparently (as I can see from various bug reports in Fedora)
most window managers got this wrong in some way or another. For the GDM
bug (which I described above) is probably causing the problem for most users.
My solution was to install a utility called xkbset which knows about
these new X features, and turn them off. xkbset -a turns off AccessX,
which turns off that terrible
press-shift-for-10-seconds-and-your-keyboard-is-toast feature.
I run this xkbset -a as part of the session startup, and haven't had a
keyboard hang since.
Tanks for the tip. Adding to my ~/.xsession script.

For DNS resolution to work you need to have a valid 'nameserver' entry in your

On Thu, Jun 21, 2012, Nadav Har'El wrote about Re: Python question - first

My example program actually *forked* right before that first call.
It turns out that (at least, this is my understanding now) memory
allocation -
in Python but also in C - is significantly slower during this first call,
but
...
The short explanation is copy-on-write page faults.
I have since discovered that there's another reason for slow memory
allocation after a fork, even if we avoid copy-on-write by filling the
parent's malloc arena before the fork:
When the child allocates *new* memory with sbrk(), and later uses it, minor
page faults happen causing the kernel to zero the new pages before the
program can using it. This zeroing takes time, but is important (for
security reasons). What worries me more, though, are these minor page
faults. These happen lazily - only when I access a page, a page fault
happens, so I am getting one minor page fault per page, and these appear
to have significant overhead (page table locks, TLB flushes, or I don't
know what).
What I'd rather happen in the child is that when sbrk() allocates new
memory, the kernel immediately maps and zeros all these pages - and
doesn't wait until they are actually used (which I know they will).
Do anyone have any idea if this can be done, hopefully without modifying
the kernel? Is there some madvise() or other trick which can be used to
ensure that a large number of pages get mapped *now* instead of mapping
them one after another?
You may try using the kernel hugepage support, either transparent
(Documentation/vm/transhuge.txt), or non-transparent
(Documentation/vm/hugetlbpage.txt). When your allocated memory is on a single
huge page, the kernel must map and initialize it all in a single page fault.
You also get the benefit of smaller TLB pressure. I'm not sure whether you can
use huge pages with sbrk() though.

The driver automatically loads the firmware, which in you case seems to be

In theory cscope f t (find text) can do it, but it won't be very

Per your requirements, I'd suggest you consider using grep to filter

Not that I know of. The minimal versions of everything needed are in

I would be very much surprised if the kernel could not be built with

Maybe not on PowerPC, though
Recent kernel versions surely have all these warnings fixed. The kernel in

Re: More RAM than MemTotal

I am missing 180MB, and would like to know where they are. The problem
really interests me in the context of virtual machines, but it also exists
on my laptop (bare metal installation).
The size depends on the installation: on my laptop180MB are missing, in two
virtual machine images the numbers are 134 and 384.
The difference is between the RAM I know I physically have (or that I know
KVM was told to allocate the VM):
ladypine@alice:~/phd/c/moc$ grep RAM /var/log/kern.log
Mar 26 10:24:45 alice kernel: [34324.028293] 1048576 pages RAM
This is exactly 4G, since each page is 4k: 1048576*4/1024=4096.
and the total memory that /proc/meminfo and top think the system has:
ladypine@alice:~/phd/c/moc$ grep MemTotal /proc/meminfo
MemTotal:4009628 kB
which is a bit less: 4009628/1024=3915.65
and the gap is:
4096-4009628/1024=180.35
So: 180Mb lost, a reward for an honest finder?
Do 'dmesg |grep Memory:' on your machine. Here is the output of mine:
Memory: 3967520k/5240832k available (3402k kernel code, 1137484k absent,
135828k reserved, 3330k data, 568k init)
The sum of 'absent' and 'reserved' should account for most of the missing RAM.
See the mem_init() routine in arch/x86/mm/init_64.c (assuming that your laptop
is x86_64 based).
The (huge) absent figure comes from absent_pages_in_range() in
mm/page_alloc.c which, according to the comment there returns number of page
frames in holes within the entire RAM. I'm not sure what that means exactly.

Your kernel has probably filled its cyclic dmesg buffer. Do you see your boot

Anyway, these messages should be written somewhere under /var/log. On my

Run your target program under gdbserver like:

In the past week I had several bugs that while gdb pointed to a place X,
the actual place was several instructions prior to that position.
For example the following error message I had to an off by one bug:

0x01ddad50 ***
The instruction set that I was at, when glibc raised this exception was a
lot further then the original position of the function that caused it have
been executed.
Only by using valgrind, that I could find the exact location and figure
out, that it was another function that had the problem.
How does the modern memory management system is working then, that it takes
so much time for the problem to surface ?
This problem has nothing to do with Linux (in the sense of the kernel used).
The malloc() routine is implemented in glibc. For its malloc() implementation
glibc uses its own set of data structures to keep track of free memory chunks
and the size of allocated chunks. Note that the free() routing accepts just
one parameter, the pointer to free. glibc must then figure out what was the
size of the memory chunk that this pointer points to.
Now, if you corrupt the internal glibc data structure, glibc won't notice
until you try to call one of malloc(), free(), etc.

Some more nitpicking.
Bitrate is the number of bits per second (usually measured in kilo bits
per second, or kbps, or sometimes mbps). This means that bit rate and
bandwidth are, for all practical purposes, one and the same.
Not exactly. Bandwidth is a signal processing term. Udi, thus, refers to the
spectral bandwidth. See
http://en.wikipedia.org/wiki/Bandwidth_%28signal_processing%29.
What you (probably) meant to say was that the new encoding allows
transferring the same video quality for 30% less bit rate.
I think Udi meant to say that with the new encoding you can have 30% more bps,
or digital bandwidth, while using the same spectral bandwidth, or RF
bandwidth.

If you look for stability, and you can stand its old age, I'd recommend kernel
version 2.6.32. This version is the base for enterprise versions of both
RedHat and SuSE distributions, as well as Debian and Ubuntu LTS. The -longterm
kernel branch maintains v2.6.32 (now at v2.6.32.48, from last week), and will

I have STFW, but have been unable to find such a tool for EXT3 or below.
Is anyone aware of such a tool readily available?
Just fetch genext2fs from your local Debian mirror.

I don't know of a specific tool like this, but it sounds like something
which can easily be done with a few line shell script.

The advantage of genext2fs over a fsck wrapper is that it lets you create
device nodes in the ext2 image without having root privileges. This feature is
very convenient when generating root filesystem images.

Can you help locating the MS statement that you describe?
The MS response on this issue is at
http://blogs.msdn.com/b/b8/archive/2011/09/22/protecting-the-pre-os-environment-with-uefi.aspx.
Matthew then responded to this at http://mjg59.dreamwidth.org/6503.html.
baruch
Some relevant details, described in Mathew Garett's post (thanks Tzafrir for
the link), and some of the replies there:
1. Problems with the proposed UEFI boot standard boil down to the fact that
it lacks any means to allow the *owner of the hardware* to edit the list of
trusted keys (load new keys, delete old ones).
2. It seems to me that some aspects of this are in fact a security issue,
which should also be in the interest of Microsoft to solve (e.g. they would
probably want some means to recover in case one of their keys get stolen).
3. Some solution to the problem (a mechanism for loading keys from specially
formatted removable media) will be (is being) suggested by Garrett to UEFI
during this week's plugfest http://www.uefi.org/events/
4. Readers of this group should be interested to know that this solution
(whatever other advantages/disadvantages it might have) would allow you to
end up being able to boot kernels (or bootloaders) that you compiled
yourself and signed with your own private key.
Hence: if that MS statement contained some indication that Microsoft would
support such a solution, indeed I see no serious reason to worry.
Either way, we should follow closely for reports from the plugfest
conclusions next week.

This works up to and including gcc 4.4, but it does not work with gcc
4.5.1 or gcc 4.6.1 (the ident part does not show any keywords). The
reason seems to be that the optimizer realizes that the static const
is not used and eliminates it (remove -O2 and ident works fine).
The -O2, as well as -O and -Os, gcc options enable a set of specific
optimizations that can each be turned off. The full list is at
http://gcc.gnu.org/onlinedocs/gcc-4.6.1/gcc/Optimize-Options.html. Just go
over this list and disable each optimization, until you find the one removing
your static string.

I've encountered the opposite problem.
Files I create in a Linux text editor (Kwrite) don't open properly in
Windows Notepad. I get the entire file on one line.
Maybe there's something strange going on behind the scenes in KDE?
That's something else and relates to the way Unix and Windows define
newline.
You could run your file through the unix2dos utility prior to moving it to
Windows, and it will most probably solve your issue.
Alternatively, if you'll be using Kate (which I think is better than
KWrite), you have Tools - End of Line - UNIX (and you can change there to
Windows/DOS)

A VPN client may do one-to-one NAT of one (or more) remote hosts, and map

what does that do ?
Cancels tab expansion for files that are identified as makefiles.
how would be the inverse syntax (i.e. expand type for all that is not

set expandtab

THANK YOU
You're welcome.
Now, I just need to see how to make vi disable tab expansion for C
files if, and only if, I am editing the Linux kernel source code
My solution is to put a local .vimrc at the Linux tree top level directory
with:
set noexpandtab
set ts=8
set shiftwidth=8
and set 'exrc' in my main .vimrc. To mitigate the security implications of
this change I also set 'secure'.
The limitation of this solution is that I must edit kernel files with the top
directory as my PWD.
baruch
Either way, I edit makefiles at the same time I am editing
C/C++/Java files, but when I'm editing kernel files, that's all I'm
doing. As such, this is a much less urgent matter for me.

The closest thing to server in the ARM world is probably a NAS box. See

Mostly processing, although storage is also interesting.
Then you should go for the Coretx-A8/A9 based chips. You can have a

Does anybody know a site that lists or reviews Linux children games and their

Or can anyone recommend a specific game for a 4 year old?

If so, which udev rule would configure the mount points to be as they are

Thanks. I have some scripts that depend on the device being found at a
particular tty. How can I disable scanning so that I won't have to
change the scripts? Or, how can I tell what device is on which tty in
my scripts?
The right solution IMO is to use udev rules that instruct udev to create those
tty devices at a persistent location. To get the full information you need to
write these rules do something like the following for each tty device:
# udevadm info -a -p $(udevadm info -q path -n /dev/ttyXXX)
Then, use the info you get to write the rules according to
http://reactivated.net/writing_udev_rules.html. (Note that udevinfo that's
mention in this document is now 'udevadm info'). Put the udev rules in a file
(say, '70-persistent-tty.rules') under /etc/udev/rules.d/, and you're done.
