RFC2324 posted:KDE is, and will remain till they gently caress up horribly, my favorite DE. They're in the middle of loving it up horribly for KDE 5  Kidding, honestly. The Plasma 5 libraries/interface look very nice, and by the time they become part of a new release of KDE (that then makes it into a stable Linux distribution), everything should be very polished. There were some serious regressions in 5.0 (missing functionality and broken features) but it's coming along quite nicely. It looks like that talk of "we know early KDE 4 is a mess but we're laying good foundation for the future" was actually true.

Crotch Fruit posted:Just curious, what happens with NTFS? First, there are several possible NTFS implementations. The one included in standard Linux kernels is safe but rather plain, feature-wise: according to the documentation in the ntfs.txt included in the kernel source package, you cannot create or delete any files or directories! (Writing into existing ones is fine, so it can be used if you're storing Linux filesystems as image files on NTFS volumes.) The FUSE-based NTFS-3G has a lot more features, particularly in terms of permissions handling. I guess most even partly desktop-oriented distributions will offer this when they talk about NTFS support. NTFS has its native ACLs, which can easily be used to store the standard Unix-style permission bits. The problem is user and group identification. Unix-style filesystems usually store file ownerships as simple numbers: the UID and GID numbers you can see with the "id" command or by peeking into /etc/passwd and /etc/group. Windows uses SIDs, which are similar to UUIDs: long strings of numbers like this: code:(The same thing would happen when moving a NTFS filesystem between Windows systems, if those systems are not both part of the same Active Directory domain tree/forest.) To minimize the potential to harm and nuisance, NTFS-3G won't use Windows-style ACLs to store file permissions unless you explicitly allow it to do that. There are two ways to do it: either by specifying some mount options ("permissions" or "acl" depending on exactly what you want), or by creating an "user mapping file" to identify which Linux users and groups correspond to which Windows SIDs. If the user mapping file is used, it is normally placed into ".NTFS-3G" directory in the root directory of each NTFS filesystem. In Linux, the directory is hidden because its name begins with a dot. In Windows, you can make it hidden if you wish: for Windows, it is just a data file with no particular meaning. There is a Linux command named "ntfs-3g.usermap" that can help you in creation of an user mapping file. It examines existing files on a NTFS filesystem, chooses some likely candidates and presents them to you for identification. You then either select the name of the Linux user or group that you want to match the user or group owning the file, or indicate "don't know". Then it gives you a user mapping file, which you can plop into the appropriate location on your NTFS filesystem(s). Then unmount & remount your NTFS filesystem(s) or just reboot so that NTFS-3G can detect the user mapping file at mount time and start presenting and storing the file ownerships and permissions in a sane manner. (Whew... again I've made a wall of text!)

Or is the sacred order of the I would pay attention to see if the job wants a Linux administrator or a Linux systems programmer, as they are vastly different positions. If it's an admin job you need to learn all about making Linux machine do things from a command prompt, like what commands to see what programs are running, process a bunch of log files, etc. If it's a systems programmer job you need to learn how to write Linux/POSIX code. There is some overlap between the two, but each is pretty specialized and can go very deep into knowledge particular to each field.

It means "we expect you to not be a bumbling fool with this totally different operating system, which almost always has other users on it and you can't get admin rights to try random poo poo from Google if you need something or get stuck. "NoSQL" is a buzzword. "Big Data" is. "Web 2.0" is. (All of these had and have meanings, but their use on adverts usually meant nothing. They don't feel like they need to put "Windows" on there because you almost certainly know enough to get around. Do you do systems programming on Windows? Like writing services in MFC C++? Or even .NET? Why would you do this in Linux if you don't know enough about it to feel comfortable asking for jobs that list Linux? Read a certification study guide (LPIC 1-2, RHCSA/RHCE, whatever) or the Centos/FreeBSD/Fedora deployment and admin guides. And learn how to use the shell enough to do daily stuff like listing/moving/copying files, listing and killing running processes, displaying text files, etc. Then pick a language. It can be C, but you'd be better off with Python or Go or whatever web language if you're a web guy. Learn how it basically works (if it's a new language, you'll be fine. If it's C/C++, learn how autotools/automake work) If you're an admin, you don't need to know a language right away, but you'll be a better one if you do, and you'll never advance if you don't learn one. Now you can apply for jobs that ask for "Linux".

Does anybody here use Virtual Private Clouds in AWS? I don't have a VPN configured with it so I have to assign every instance a public elastic IP in order to connect to it. I use a security group to ensure only the my IP address can hit ssh & https on the box. I was talking to the guy at work that can setup the VPN for me and he doesn't want to do a VPN to the VPC, he said it's better to do the security group & public IP address. This seems crazy to me, I don't know how to convince him otherwise though. Especially since AWS only gives me 5 elastic IPs (i'm sure I could request more) but I don't even need these machines to be publicly accessible, just the load balancer.

What's the output if you type sudo apt-get install --dry-run kubuntu-desktop into a console? The --dry-run means it will only show you what it would do, but it won't touch your system.

I want to use a USB wifi device, the Rosewill rnx-n180ube, on my 3.13 kernel Xubuntu laptop (64 bit). However, the only linux driver available from http://www.rosewill.com/products/1721/ProductDetail_Download.htm is for the 2.6 or 3.0 kernels. I tried make'ing it anyway from source but it didn't work because I assume my 3.13 kernel's development files are what's causing all the problems. I tried to apt-get some old 3.0 linux development files but that was a non-starter. A google search didn't turn up anything helpful. Am I totally out of luck here? I looked through the makefile but the only relevant option that is easily settable is to choose PC or Android or Arm. How can I compile a driver for a new kernel if it was only made for a really old one?

So is that the sort of thing Steam could solve? I mean, if instead of each game having to target each different distro for compatibility, they target Steam and then each distro works on making itself compatible with the steam libraries. Kind of like how Direct X is supposed to work under windows. I thought OpenGL was already supposed to be doing this but then I haven't really paid attention for a looong time, and then only from the windows side of things.
