Another approach is to use Access Control Lists, a superset of file permissions.
First of all, we have to install the acl package:

You cannot reward users for their edits, but the system (AU) rewards them with 2 reps, so there's no need to do that. If you still feel you want to do something for them, you can upvote their posts.
@msPeachy But via edits it is very hard to get the points you have. You must have edited hundreds of answers.... Also, this way, you are not able to earn points in the future with something you did in the past....
As Compiz Grid is not supported in ubuntu-2d, I am looking for alternative to tile windows.
This video shows that xfce4 and xfwm4 can snap windows to a part of the screen. I would like to do that by keyboard shortcuts.
I have already installed xfce4and xfwm4, but I don't see which one in the fo...
@jokerdino I see no need. If you choose to delete it, I'll delete mine. But as things stand, it's clear that the <!-- ... --> method has been tested and works. There's arguably something beneficial in that. I don't feel skittish about having been mistaken or anything. :-)
Oh, yeah, I figured there was enough info without it. But your answer is self-contained--I think there's nothing wrong with you deleting your comment. Whatever you prefer. I really don't have a position on this. :-)
Hello! I asked this question http://askubuntu.com/questions/173386/problem-with-the-logitec-orbicam-webcam-how-to-troubleshoot-it and although it has a nice amount of views (46 so far) I haven't received any answers yet. Any suggestions on what could I do to improve my question and get an answer? Thank you! :-)
Ok, so there's the buzz of Canonical (wanting to) switch for new Ubuntu version from the GNOME default desktop to their own Unity shell. (I hope that's accurate.)
It seems I can not totally fathom what Unity actually is. For looking at its homepage it currently is firmly targeted at netbooks and...

I haven't used Ubuntu since like version 9 or something. Now that I just downloaded and installed v12, I want to know what all the talk about "Unity 3D" is about? Am I right to assume that Ubuntu now uses the Unity 3D? And am I right to assume that Unity is just the theming scheme of Ubuntu? (Pre...
@jokerdino Coz he just made the exciting discovery, that he thinks is a discovery of the decade? Or maybe he's hinting that he likes things a li'l kinky :P
It could be X/env, it could be an assert i'm not running as root somewhere (which seems google-y to me), it could be part of it tries to drop privileges and part of it doesn't...

I am trying to troubleshoot my webcam and make it work with skype.
One workaround that is often suggested is to LD_PRELOAD the v4l1compat.so file. But when trying that, I get an error message:

@Mahesh why would you have your avd and your sdk installed as two different users? running things as root...fine in some situations, but this isn't one of them
@nitstorm That guy, @ObsessiveFOSS and @jokerdino had quite the debate trying to solve this question in chat yesterday. Then again, he claims to run "the one stop shop for technology and gadget information", so this seems like a silly question to ask :P
@EliahKagan: what exactly do you mean by "many commercial routers expose their WAN IP's on both their WAN and LAN interfaces" :/ (and I agree re nmap, was just pointing out the one-liner :)
btw, how can we shout to the community to pls not flag/ or cast close votes without leaving a comment, coz then it makes you wonder why this thing got into the close vote queue
yeah, but sometimes, it's plain crazy, some guy wants to nuke Ubuntu and go back to the dark side, so it got marked as not a real question instead of a dupe
@izx Suppose you forward a port from a machine on LAN, through your NAT router. Then the service running on the machine on LAN is accessible from the WAN side of the NAT router (i.e., the Internet), by connecting to that port on the router's WAN interface's IP address. That's what it means to be port forwarding.
Have you noticed that there are some very usual problems? For example the one that the internet connection disconnects after some time and the blinking cursor on startup and it is not possible to boot......
But suppose you try to access that port from inside the LAN, by entering the IP address of the router's WAN interface. There is no reason to expect that this would work, and on NAT routers people set up themselves hosted on GNU/Linux, FreeBSD, OpenBSD, it usually doesn't. But on most commercial home / small office routers, special rules are present to make this work seamlessly (including ones that are Linux based).
@izx When people switch from commercial home routers to solutions like IPCop, SmoothWall, or m0n0wall, they are often surprised that this doesn't work (since connecting to the WAN side of the router from on the LAN is often used to test if port forwarding or DMZ is correctly configured).
@izx I'm talking about when the port is forwarded. Even when the port is forwarded, that doesn't necessarily mean you can access it through the port forward from inside the LAN.
@EliahKagan I think that's still convoluted, e.g. it may mis-imply that e.g. port 646 should be open on the router's LAN IP (192.168.1.1, etc) as well, if forwarded
Funnily enough, port 646 also appears to be used by rpc.statd, an NFS child file-locking daemon...
@izx i think that whole debate is solved with "if you're using port forwarding and local services, you should set up internal dns properly. problem solved"
@izx Well it's the IP that's exposed on/through both interfaces; that's not the same thing as saying the port is exposed through both interfaces' IPs. :-)
@izx I actually was not aware of that. Thanks. However, since the other ports were "green" in the scan, it's probably the router that was being scanned, and it's unlikely that port was forwarded either automatically or manually.
I previously asked this when I was using Ubuntu through Wubi. I was told that Wubi didn't support hibernation, so I ignored the issue and restarted the computer whenever it tried to go into hibernation.
Last night I decided to install Ubuntu and use it as my main OS. One of the first things I ch...
@hakermania If you really ask hard to find questions, you better be prepared to follow-up and help people help you -- like this one guy who had an odd network-PulseAudio issue, and allowed me to screen-share to solve it. If you hit-and-run, well, that's @jokerdino's domain right now :)
Well, in most cases if you know how you fixed it you can just write it out in an answer. It's the troubleshooting/testing that's much easier assuming you can't independently replicate the problem...
