Know anybody, how i can install NodeJS on dd-wrt, openwrt or freewrt system?
Or Maybe on any Router with one on these systems: http://en.wikipedia.org/wiki/List_of_router_or_firewall_distributions

I stumbled across one fellow on Twitter who claimed to have done so back in 2011 April and offered a high-level overview of the process. My research indicates that this will only be possible on little-endian chipsets (e.g. "mipsel", as on the ASUS RT-N16) as even the MIPS version of v8 does not support big-endian implementations of that architecture (e.g. as the Atheros chipset on the Buffalo WZR-HP-AG300H is using).

Sorry, couldn't find any references that indicate it's been done. I suggest checking out the dependencies for Node.
You will need at least the following:
gcc4-g++
git
make
pkg-config
zlib-devel
openssl-devel
openssl
python
Note, that is from the older Cygwin compile instructions so they might not be exactly right.
If you can find all of those for your router OS then it should be possible. Just note that it will take a LONG time to compile.
You may also struggle with memory as most routers are severely lacking. This question on Google has a bit of information.

I've been trying to update eglibc to fix a Debian 6 Squeeze system that is vulnerable to the GHOST exploit, but I haven't been able to so far.
I've gone through the relevant instructions here but my system still remains vulnerable. (I am checking vulnerability by running the script located here). My libc version after update is 2.11.3-4.
I notice that on Debian's Security Tracker that there is a fixed version of eglibc for eglibc on squeeze (lts), but not squeeze. I am running squeeze.
How can I fix my version of squeeze? Do I need to upgrade to squeeze (lts)? If so, is that a painful and involved process or a simple and easy process?
Much appreciated - thanks.
See a similar question on SO. You really do need to upgrade to Squeeze LTS, but it’s simple enough if you’re running i386 or amd64; the Debian wiki has all the info.
Get eglibc's source and compile to a .deb yourself.

Does anyone know any way how to port ZBar to NaCl? I'm making a pnacl project and need to read a QR code from a image.
I'm working on linux.
thank you for help!
The naclports project has many ports of libraries to Native Client, and some common infrastructure to do so. There isn't a port of zbar yet, but I've filed a bug for it here.
From the zbar README:
...
The scanner/decoder library itself only requires a few standard
library functions which should be avilable almost anywhere.
The zbarcam program uses the video4linux API (v4l1 or v4l2) to access
the video device. This interface is part of the linux kernel, a 2.6
kernel is recommended for full support. More information is available
at
http://www.linuxtv.org/wiki/
...
It sounds like it shouldn't be too difficult to get the scanner/decoder part ported. If you're interested in helping with the port, it's best to continue this conversation on the bug I linked above.

I am looking for a mini-pc compatible with Ubuntu. It is to be used as a "infoscreen" (displaying an activity list). By compatible i mean that drivers must be available, at least for graphics and wifi.
It must have the following capabilities:
Run MonoDevelop for C# compatibility*
Run LAMP (Apache, MySQL and PHP)*
Have wifi - preferably built-in.
Preferably resolution up to 1920x1080
Low price :-)
* I know this is possible with Ubuntu, but someone might suggest an Android mini-pc or some other kind, that i don't know of. As long as the above is possible, i don't care which brand or type it is.
Can anyone recommend a specific mini-pc or maybe a brand?
I've tried the Zotac Zbox Nano VD01 Plus, but that was no succes. Only old version of Ubuntu were supported and i never got the wifi driver fully working.
Thank you in advance!
I'd recommend a Raspberry Pi with Raspbian. it doesn't have wifi, but there are adapters.

I have my app working on OSX and Win, but am having a hard time tracking down all of the required dependencies for Linux. Ideally I'd like to be able to run it on Fedora, CentOS and possibly Ubuntu. Ubuntu is lower priority however.
Will someone help me figure this out? I can get my way around Linux decently well but am not a pro. This has me quite stumped.

Currently your tarball contains the binary .so files for Qt 5. This is usually not the way to do it on Linux. You can either provide the source code of your program and let the users build it for themselves, or you can kindly provide a pre-built package (.rpm or .deb) for the Linux distribution in question. This means building packages specifically for a certain release of Fedora, again for CentOS, and again for Ubuntu. These packages would depend on libqt5, a package provided by the Linux distribution itself.
For finding out more dependancies, use ldd:
$ ldd program
Running the same compiled binary across different Linuxes is usually a no-no because of differences in the versions of the underlying shared libraries, although some companies do it, namely for commercial games.
If you use static linking then it can work. Until they change something big in the kernel.
You should also take the target architecture into consideration: ia32, amd64, or maybe something else.
Maybe this question is better answered at ServerFault.

I would want to install a free Linux OS in my laptop. I am not a techie. I am looking for Linux OS which will have inbuilt features for Fn(Function) keys. Please suggest me if you know any particular Linux OS with these features.
This OS have a laptop version. Easy to use, and supports the newest hardwares:
http://www.ubuntu.com/download/desktop
There are so many choices. Ubuntu is the defacto first distro, although I don't really care for it ever since they went to Unity and Gnome 3. I would rather use Mint with Cinnamon.
A good start is to look at something like Linux Watch http://distrowatch.com/ and see what distros sound good to you, then burn the live disk and check it out. If you like it you can then install it.
