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 thought this would be the appropriate community to ask this question.
Back when Apple had their developer's conference over the summer, I was aware that they were going to make Swift open source.
I was under the impression that Xcode would not be ported to Linux, but I was under the understanding that some entity would create a development program to imitate Xcode.
Therefore, I am wondering about new developments in this situation.
Does anyone have any more current knowledge about this topic or any experiences with this?
There's a misunderstanding here.
Swift the programming language is open source.
It doesn't mean that iOS or OS X frameworks, like Cocoa, UIKit, etc, are available in Linux - Apple didn't announce that.
When you make an app for iOS using Swift, you have to import UIKit and other libraries - those are the iOS parts.
Swift is just the language - you can already make an iOS app with Ruby, Objective-C, JavaScript, etc, using these same libraries.

I would like to start a new Nodejs project soon, and I was wondering if I should try out Dart VM instead. I read that Dart VM is not finished yet, but I should already have everything I need (web server, sockets, files i/o), and I would enjoy discovering something new.
Does anyone have experience with both Node and DartVM, and can tell me what are the major differences/problems to expect, or if Dart VM is really not usable for real server side projects yet?
I'm not asking for your personal preferences, but for actual problems I might encounter based on your experience.
I worked on a small project, a few months ago, using Dart as a server side language. I really enjoyed it and didn't have any specific problem beside the occasional "there's no package for that" - there are way more packages for Node than for Dart. This could be something to consider for development speed (no need to reinvent the wheel). Other than that, everything went fine.
As a note, it is being used live by others: top 5 live websites already using Dart

Experienced Windows programmer wants to learn Linux programming.
I have a Windows 7 machine. No Linux installed yet.
I have to learn from scratch including installation and then programming.
I have been programming in C/C++ for lots of years - nothing to learn here.
Just the Linux stuff.
Any good tutorials that match the situation?
How long should it take?
To get used to a linux environement, I think you should first get a live CD/USB of any Linux distribution that you want. By example you can follow this tutorial for Ubuntu or this one for Fedora.
Then, you can open a terminal and follow another tutorial like this one, to start programming on Linux.
Finally, if you need to install the Linux distribution, you should know that nowadays every good Linux distribution have a very easy installer directly available from their live CD/USB. Just put your basic configuration and click next !

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.

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.
